Description
[0001] The present invention relates to a household appliance for
storing at least one bottle containing a beverage and having a neck
that is open, in particular a bottle of wine that has been uncorked
and/or partially consumed.
[0002] In order to preserve wine, or more generally any beverage,
in an open bottle, it is well known that it is necessary to prevent
the beverage from coming into contact with the oxygen of the air,
since otherwise its taste and organoleptic properties in particular
will deteriorate rapidly. Furthermore, it is preferable to keep the
bottle at a given temperature, depending on the quality of the
wine, this temperature generally being lower than room temperature
in rooms that are occupied on a daily basis.
[0003] In the field of professional wine service, in particular in
restaurants, there exist appliances for this purpose that make use
of a first pipe that opens out into the top portion of the bottle
so as to apply a continuous pressure of a gas that is inert, such
as nitrogen, this pressure advantageously being used to drive wine
out through a second pipe so as to serve the wine without it being
necessary to remove the system that supports the first and second
pipes and that is fitted in leaktight manner to the neck of the
bottle. Appliances of that kind require the second pipe to be
immersed in the volume of wine down to the bottom of the bottle,
such that the appliance must normally be cleaned each time the
bottle is changed. Such handling is time-consuming and in any event
completely ill-suited to domestic use, which by definition must be
simple and easy for a non-professional user. In addition, the cost
of that kind of appliance remains high.
[0004] The invention thus applies to household appliances, i.e. to
appliances that seek to increase comfort and make life easier at
home, and in particular it relates to household appliances for
preservation purposes. In this field, a first known solution,
derived from the above-mentioned professional solution, consists in
injecting an inert and/or heavy gas into an uncorked wine bottle
prior to reclosing the bottle with its original cork. Using an
inert gas requires the air that was previously contained in the
bottle to be expelled therefrom, while using a heavy gas does not
require the entire bottle to be filled with the gas, since the
presence of a "gas buffer" on the free surface of the wine
suffices, in principle, to prevent the wine oxidizing. Once the
bottle has been recorked, it is then stored in a cabinet or in a
container, preferably having its inside temperature adjusted to the
quality of the wine stored in this way. It can be understood that
the handling operations needed to preserve the wine in an open
bottle are thus numerous and fiddly for the user, and that they
take a long time, which means that they are perceived as being
similar to household chores, far removed from the pleasure a user
seeks in having a good wine available for consumption over several
days.
[0005] Another known solution consists in using a suction head for
evacuating the bottle, and in known appliances this is presented in
the form of a special stopper incorporating a valve: after the
special stopper has been fitted to the neck of the bottle in which
wine is to be preserved, the user actuates a vacuum pump, either
manually or using electrical power, so as to suck the air contained
in the top portion of the bottle out through a passage that is
defined in the special stopper. Once a satisfactory level of vacuum
has been reached, the vacuum pump is separated and the special
stopper is left in place, with its valve preventing outside air
from penetrating into the top portion of the bottle. The bottle is
then put away in a cabinet or a container, which is preferably
refrigerated. Evacuating the bottle thus avoids the need to make
use of an inert and/or heavy gas, which would present significant
cost, which might not be harmless in terms of health and long-term
effects on the environment, and in any event which presents a
"chemical" aspect that some users find unpleasant. In addition, in
order to reach a satisfactory level of vacuum inside the bottle,
handling such suction heads can be particularly troublesome because
of the length of time it takes the user and because of the sealing
difficulties involved.
[0006] Furthermore, both with appliances using inert and/or heavy
gases and with appliances that enable the bottle to be evacuated,
the quality with which the wine is preserved generally falls off
rapidly since, insofar as the free surface of the wine is greater
inside a partially consumed bottle than in a full bottle, where the
free surface of the wine is in the neck, outside air tends
naturally to be drawn back in through the stopper closing the
bottle.
[0007] The object of the present invention is to propose a
household appliance for storing at least one uncorked bottle, which
appliance is extremely easy and quick to use, while guaranteeing
high quality preservation that is stable over time.
[0008] To this end, the invention provides a household appliance
for preserving a beverage contained in at least one bottle that has
already been opened, such as an uncorked bottle of wine, the
appliance being as defined in claim 1.
[0009] The idea underlying the invention is to seek great
simplification in the handling that a user needs to perform, so
that the user needs to perform only the natural and agreeable
actions of taking hold of an opened bottle and pouring out the
liquid it contains, where necessary several times over, and then
placing the bottle in or returning it to a predetermined location
in which the appliance in accordance with the invention guarantees
that the liquid remaining in the bottle is preserved. For this
purpose, the idea on which the invention is based is to avoid any
need for the user to move the neck of the bottle manually up to the
suction head for evacuating the bottle, by making provision for
this movement to take place automatically, or at least for it to be
assisted by the appliance, by virtue of its means for moving the
suction head. In practice, the head is mounted to be movable
relative to the case of the appliance, with the path followed by
the head in movement being predetermined so that when the user
places or returns the opened bottle in a predetermined stationary
location relative to the case, the above-mentioned means for moving
the head guide it effectively to the neck of the bottle, regardless
of the height of the bottle. Furthermore, the above means for
moving the head are designed, in accordance with the invention, to
press and hold the head against the neck of the bottle so as to
guarantee good sealing between the head and the neck. A vacuum can
then pass effectively through the suction passage defined by the
head so as to evacuate the bottle, i.e. reduce its inside pressure
to a level that is satisfactory for preserving the liquid it
contains. Typically, in order to preserve wine, the level of the
vacuum needs to reach more than 0.1 bar less than atmospheric
pressure. In addition, the way these means for moving the head
press the head in leaktight manner against the neck of the bottle
is reproducible and stable over time, thereby guaranteeing a high
level of preservation for the liquid contained in the bottle.
[0010] In practice, actuating the vacuum source, such as a vacuum
pump, and acquiring the means for moving the head, in particular
the portion of said means linked to move with the head, can be
controlled in different ways. Advantageously, user participation in
these actions is minimal, the user doing no more, for example, than
to press directly on a switch, or to close a door, the door
co-operating with the case to define a compartment for storing the
bottle, and the compartment preferably being refrigerated, or to
apply a very simple drive force to the head, e.g. pushing it
downwards. Sensors for identifying the presence of a bottle in its
predetermined position relative to the case may even be provided
for controlling the above-mentioned actions, thereby further
reducing the contribution of the user in said actions. In any
event, it will be understood that once these actions have started,
the user can move away quickly from the appliance in accordance
with the invention, since the appliance can advantageously move the
head automatically until it makes leaktight contact against the
neck of the bottle and then, likewise automatically, it can
evacuate the bottle without any need for the user to take further
action. In other words, the appliance of the invention operates, at
least to a large extent, in time while the user can be doing
something else.
[0011] Additional characteristics of the appliance of the invention
that are advantageous taken in isolation or in any technical
feasible combination are specified in dependent claims 2 to 15.

refrigerator element, analogous to FIG. 3.
[0029] FIGS. 1 to 3 show a household appliance 1 for conserving two
bottles of wine 2 and 3. Each bottle 2, 3 includes a neck 4, 5 at
its top end enabling the wine to be taken, i.e. enabling the wine
contained in the bottle to be poured out therefrom. The necks 4 and
5 are uncorked, i.e. they do not have their own stoppers, typically
made of cork, that serve originally to keep the bottle closed in
leaktight manner to enable it to be transported from a bottling
site to an uncorking site where the consumer removes the original
cork, in order to consume the wine contained in the bottle.
[0030] The appliance 1 comprises a case 10 for storing bottles 2
and 3. In the example shown in the figures, the case advantageously
presents an outside shape that is generally cylindrical, on a
circular base and centered on a vertical axis X-X. The inside
volume of the case 10 is subdivided into two main sub-volumes,
considered as being located respectively at the front and at the
rear, it being understood that when the appliance 1 is in normal
operation, the front sub-volume faces towards the user while the
rear sub-volume 12 faces the other way. These front and rear
sub-volumes are separated from each other by a vertical partition
14 permanently incorporated in the case 10 and extending in a
diametral plane thereof, i.e. in a plane containing the axis X-X.
The front sub-volume is thus defined, at its rear, by the partition
14, towards the top, by a ceiling wall 16, and towards the bottom
by a floor wall 18. In addition, the front sub-volume is subdivided
into two lateral compartments, respectively a left compartment 20
and a right compartment 22 as seen by the user looking at the
appliance 1 from in front. For this purpose, the compartments 20
and 22 are separated by a vertical partition 24 lying in a
diametral plane of the case 10, and forming a plane of symmetry for
the compartments 20 and 22 in this example. On its side remote from
the partition 24, the compartment 20 is closed by a side wall 26
which, in this example, corresponds to a portion of the cylindrical
shape of the case 10. Symmetrically about the partition 24, the
side wall 28 closes the right compartment on its side remote from
the partition 24.
[0031] The compartments 20 and 22 are dimensioned to receive
respective ones of the bottles 2 and 3 in a vertical configuration,
with their bottoms bearing in stable manner on the floor wall 18
and their necks 4, 5 directed towards the ceiling wall 16. For this
purpose, at the front of the case 10, the partition 24 and the
walls 16 and 18 define firstly in co-operation with the wall 26 an
opening 30 giving access to the compartment 20 for the bottle 2,
and secondly in co-operation with the wall 28 an opening 32 giving
access to the compartment 22 for the bottle 3.
[0032] In optional but preferred manner, the compartments 20 and 22
are refrigerated, i.e. they are associated with refrigerator means
adapted to lower the temperatures inside the compartments compared
with ambient temperature outside the case 10. The refrigerator
means may be of any known type, and preferably, as shown, it is in
the form of a single Peltier element 34, i.e. a single
thermoelectric element suitable for converting electrical energy
into a flow of heat. As shown in FIGS. 1, 3, and 4, the Peltier
element 34 comprises a main body 36 generally in the form of a
rectangular block and permanently fastened to the partition 14,
passing through it and extending over substantially the entire
horizontal dimension thereof. In a manner that is not shown in the
figures, the body 36 contains thermoelectric components suitable
for generating a flow of heat between the cold front face 38 and
the hot rear face 40 of the body 36. For this purpose, each of its
faces 38 and 40 is constituted by an air heat exchanger, in
particular in the form of a metal radiator structure.
[0033] On its rear face 40, the body 36 is fitted with a fan unit
42 that stirs the air in the rear sub-volume 12. On its front face
38, the body 36 has two fan units 44 and 46, serving to stir the
air contained in the compartments 20 and 22, respectively. For this
purpose, the front face 38 is split in its middle portion by a
vertical groove for receiving the partition 24, as can clearly be
seen in FIG. 3. In operation, the partition 24 thus isolates the
compartments 20 and 22 thermally from each other.
[0034] By having bottles 2 and 3 that contain respective wines
having different qualities, associated with respective different
preservation temperatures in storage, the structure of the Peltier
element 34 presents a particular advantage. Since the compartments
20 and 22 then need to present different internal temperatures, the
thermal stresses on the front face 38 of the element 34 are
asymmetrical on opposite sides of the partition 24. In other words,
assuming by way of example that the compartment 20 needs to be
refrigerated more than the compartment 22, then the portion of the
front face 38 carrying the fan unit 44 is stressed thermally to a
greater extent than the portion of said face 38 carrying the fan
unit 46. This leads to large refrigeration capacity for the
compartment 20, in particular to refrigeration capacity that is
greater than that that would be obtained by a standard Peltier
element having only one fan on its cold side, for constant
electricity consumption.
[0035] To maintain substantially constant temperatures in the
compartments 20 and 22, the case 10 is fitted with two movable
doors 50 and 52. Each door 50 and 52 is movable relative to the
case between a position where it closes the corresponding opening
30, 32, as shown for the right compartment 22 in FIGS. 1 and 2, and
an open position where it releases access to the opening, as shown
for the left compartment 20 in the figures. Advantageously, as can
clearly be seen in FIG. 2 where numerous components of the
appliance including the Peltier element 34 are omitted for reasons
of clarity, each door 50, 52 is generally in the form of a portion
of a cylinder that matches the cylindrical outside shape of the
case 10 and that is centered on the axis X-X. As a result, each
door 50, 52 is mounted on the case 10 so as to pass between its
closed and open positions by moving generally in rotation about the
axis X-X. This movement in rotation is represented by an arrow 54
for the door 50 passing from its open position towards its closed
position, whereas the door 52 passing from its closed position to
its open position is represented by an arrow 56.
[0036] Each compartment 20, 22 is fitted internally with a head 60,
62 making it possible, as explained in greater detail below, to
evacuate the corresponding bottle 2,3, i.e. to extract a large
fraction of the air present in the top portion of the bottle,
between the free surface of the wine it contains and the top end of
its neck 4, 5. The heads 60 and 62 are identical to each other, the
head 60 being shown in greater detail in FIGS. 5 to 8, such that
only the head 60 is described in detail below, it being understood
that the head 62 presents the same arrangement.
[0037] As shown in FIGS. 5 and 6, the head 60 comprises a main
tubular body 64 of longitudinal central axis Z-Z that extends
vertically, in operation. At its bottom end, the body 64 is
surrounded by an outer edge 66 extended in diametrically opposite
directions relative to the axis Z-Z by two horizontal branches 68.
The top end of the body 64 forms a tube 70 for connection to a
flexible hose 72 (FIGS. 1 and 2) connected at its end remote from
the head 60 to an electrically-driven vacuum pump 6. The hose
connecting the head 62 to the same vacuum pump 6 is referenced 74
in FIGS. 1 and 2. In the figures, the vacuum pump 6 is shown in
highly diagrammatic manner for the purpose of understanding the
invention, it being understood that in practice it is arranged and
hidden in the rear sub-volume 12 of the case 10 where it is powered
electrically.
[0038] In its main portion, the body 64 is provided internally with
a valve 76 that is permanently fitted, e.g. by screwing an outside
thread of the valve into inside tapping of the body 64. The valve
76 is a commercially available component and it is not shown in
detail in the figures, it being specified that it is partially
hollowed so as to put its top and bottom ends into fluid flow
communication therethrough when used under specific conditions
described in detail below.
[0039] The head 60 also includes a base 78 arranged essentially
beneath the body 64 and presenting a generally tubular shape,
centered on the axis Z-Z. The bottom end of this base 78 is shaped
as a truncated cone, thereby defining a frustoconical outside
structure 80 centered on the axis Z-Z and flaring towards the body
64.
[0040] In its main portion, the base 78 is provided with an annular
outside flange 82 extending around the entire periphery of the
base. On its bottom side, the flange 82 is permanently secured to a
flat gasket 84 centered on the axis Z-Z, with the top end of the
frustoconical surface 80 terminating thereat. On its top side, the
flange 82 is provided with an O-ring 86 centered on the axis Z-Z
and fitted around the tubular body of the base 78.
[0041] At its top end, the flange 82 is also provided, in permanent
manner, with two vertical pegs 88 that are diametrically opposite
about the axis Z-Z. The pegs 88 enable the base 78 to be assembled
to the body 64, and for this purpose they are slidably received in
two complementary holes 90 passing vertically through the branches
78. The base 78 is thus movable in translation along the axis Z-Z
relative to the body 64, by each peg 88 slidably co-operating with
its hole 90. The movements in translation between the body 64 and
the base 78 are limited, downwards, by the flange 82 against which
the bottom faces of the branches 78 can come into abutment, and,
upwards, by screws 92 permanently fastened to the top ends of the
pegs 88 and having heads that can come into abutment against the
top faces of the branches 78, with respective washers being
interposed therebetween.
[0042] The base 78 is thus movable relative to the body 64 between
a low extreme position shown in FIG. 6 in which the base and the
body are spaced apart from each other, with the top end of the base
being received in non-leaktight manner in the bottom opening of the
body 64, and a high extreme position shown in FIG. 7 in which the
base and the body press vertically one against the other, with the
O-ring 86 being interposed between them, thereby sealing the
connection between the top opening of the base 78 and the bottom
opening of the body 64. In this high position, the bottom end of
the valve 76 presses against a horizontal bridge of material 94
extending across the top opening of the base 78, such that via
internal arrangements of the valve 76 that are not shown, the
central through orifice 96 of the body 64 is put into fluid flow
communication via the valve with the through central orifice 98 in
the base 78. These two orifices 96 and 98 then form an air suction
passage 100 between the bottom end of the base 78 and the top end
of the body 64. In the low position of the base 78, the bottom end
of the valve 76 is spaced apart from the bridge 94, such that by
means of the above-mentioned internal arrangements, the valve 76
isolates the orifices 96 and 98 hermetically from each other, which
amounts to closing the passage 100.
[0043] The appliance 1 also includes mechanical means 110 for
moving the head 60 relative to the case 10, and shown in FIG. 1 but
not in FIG. 2. In practice, the means 110 are duplicated for moving
the respective heads 60 and 62 independently of each other, it
being understood that each set of means 110 presents a structure
that is identical, being arranged in a respective one of the
compartments 20 and 22. The means 110 associated with the
compartment 20 are described in detail below, it being understood
that the means 110 associated with the compartment 22 are
constituted by the same components as those described below and are
given the same numerical references in the figures.
[0044] As shown in FIG. 1, the means 110 comprise a horizontal bar
112 having its longitudinal ends received in respective vertical
slideways 114 and 116, that are fastened respectively to the wall
26 and to the partition 24. Co-operation between the longitudinal
ends of the bar 112 and these slideways 114 and 116 enables the bar
112 to be guided vertically relative to the case 10.
[0045] In order to drive the bar 112 mechanically relative to the
case 10, the means 110 include movement transmission elements
between the bar and the corresponding door 50. In particular, in
the embodiment described, these transmission elements are designed
to transform the rotary movement of the door 50 about the axis X-X
between its open and closed positions into vertical movement in
translation. For this purpose, the above-mentioned transmission
elements include, for example, a vertical wormscrew 118: that is
driven in rotation about its axis by the door 50; that meshes with
a tapped nut 120 secured to the case 10; and that has one end
secured to the bar 112. As a result, when the door 50 goes from its
open position to its closed position, the screw 118 moves in
translation so as to move the bar 112 from a high position, as
shown in the compartment 20, to a low position, as shown in the
compartment 22. Conversely, when the door 50 goes from its closed
position to its open position, the bar 112 is moved from its low
position to its high position, because the transmission of movement
by the screw 118 is reversible. Naturally, other embodiments of the
transmission elements can be envisaged.
[0046] The means 110 for moving the head further include two
vertical rods 130 and 132 connecting the bar 112 to the head 60.
Each rod 130, 132 is mounted to slide vertically both through the
bar 112 and through one of the branches 68 of the body 64. Means
for stopping movement in translation, such as clips 134, prevent
each rod from disengaging downwards from the bar 112 and from
disengaging upwards from the branches 68. The bar 112 and the body
64 are normally spaced apart vertically from each other by a spring
136 interposed between them, advantageously being arranged around
one of the rods 130 and 132.
[0047] There follows a description of how the appliance 1 is
used.
[0048] Initially, it is assumed that the compartment 20 is empty,
with the corresponding door 50 open. The user who has uncorked the
bottle 2 and has consumed only a fraction of the wine it contained,
places the bottle manually in the compartment 20, vertically under
the head 60. The user is advantageously assisted in appropriately
positioning the bottle relative to the head by an element 140 that
is secured to the case 10 and that is shaped for this purpose. In
the embodiment shown in the figures, this positioning element 140
is in the form of a fork with the bottle 2 being inserted between
the front ends of its branches, thereby being progressively
centered between the branches when the user pushes the bottle
rearwards, until it comes into abutment against the end where the
branches meet each other, as shown in FIGS. 1 and 2. In this
predetermined stationary position for the bottle 2, the neck 4 is
situated vertically beneath the base 78 of the head 60, as shown in
FIGS. 1 and 6.
[0049] After letting go the bottle 2, which remains in stable
manner with its bottom standing on the floor wall 18, the user
causes the door 50 to go into its closed position. In practice, the
user pushes the door manually, in particular using the same hand as
was previously used for putting the bottle in the compartment 20,
or in a variant the user presses a finger of that hand on a switch
for controlling motor drive, in particular electrical drive of the
door 50. The door thus goes from its open position to its closed
position by moving in rotation about the axis X-X, as represented
by arrow 54. This rotary movement is transmitted to the bar 112, in
particular by the screw 118, which converts it into downward
movement in translation, thereby moving said bar from its high
position to its low position. This downward movement in translation
of the bar 112 is transmitted by the spring 136 to the body 64 of
the head 60, as represented by arrows 150 in FIGS. 2 and 6. The
downward movement of the body 64 causes the base 78 to move in
corresponding manner by the inside faces of the branches 68 bearing
against the top face of the flange 82, until the base 78 is pressed
against the neck 4 of the bottle 2, as shown in FIG. 7. More
precisely, when the base 78 comes into the immediate vicinity of
the neck 4, its frustoconical surface 80 penetrates vertically
downwards inside the neck so that by sliding contact between said
surface 80 and the inside face of the neck, the neck becomes
progressively centered relative to the head 60, i.e. its
longitudinal axis tends to become aligned with the axis Z-Z. In the
configuration of FIG. 7, the head 60 and the bottle 2 are thus
centered one relative to the other, with the gasket 84 vertically
interposed and squeezed between the neck 4 and the flange 82 of the
base 78.
[0050] It should be understood that the spring 136 presents
considerable stiffness, in the sense that it transmits the downward
drive force between the bar 112 and the body 64 so as to press the
base 78 firmly against the neck 4, without itself being
significantly compressed. Where appropriate, the downward movement
of the rods 130 and 132 may continue, particularly so long as the
door 50 has not reached its closed position. The spring 136 then
compresses to accommodate the extra stroke of the bar 112 relative
to the base 78. The head 60 is thus effectively put into place on
the neck 4 regardless of the height of the bottle 2, i.e. the
vertical distance between the top end of its neck and the floor
wall 18. The appliance 1 thus automatically handles bottles of
different heights.
[0051] As explained above, in the FIG. 7 configuration, the valve
76 opens the suction passage 100. By then actuating the vacuum pump
6, the air contained in the top portion of the bottle 2 is sucked
out through this passage, as represented by arrows 152 in FIG. 7,
so that the top of the bottle is evacuated. In practice, the level
of vacuum achieved in the bottle, compared with atmospheric
pressure, needs to be greater than 0.1 bar, so as to be situated
around 0.3 bar.
[0052] It could also be observed that the vacuum pump 6 may
advantageously be actuated under the control of the door 50, in
particular when the door reaches its closed position, as identified
by an end-of-stroke switch that is electrically connected to the
pump. In a variant, the pump may be controlled by means of sensors
that detect the opposition to downward movement of the head 60 when
it presses against the neck 4.
[0053] It can be understood that the user does not need to wait for
a vacuum to become established in the bottle 2 in the sense that
once the user has set closure of the door 50 into operation, the
user is free to go away from the appliance 1 to do something
else.
[0054] The bottle 2 is then effectively stored by the appliance 1
with its head 60 being held firmly in leaktight manner against the
neck 4 by the means 110. Optionally, the vacuum pump 6 is
reactivated on a regular basis. Preservation by the bottle is
further improved by cooling the atmosphere inside the compartment
20.
[0055] When the user desires to consume the wine remaining in the
bottle 2, the user opens the door 50, either by moving it manually
or by operating a switch to cause it to be moved by an associated
motor. The movement of the door in rotation about the axis X-X from
its closed position to its open position, in the opposite direction
to arrow 54, causes the bar 112 to be driven upwards, as
represented by arrows 154 in FIG. 8. Initially, and where necessary
after decompressing the over-stroke spring 136, the body 64 is
driven upwards by the bar 112 by means of the rods 130 and 132
without the base 78 being driven upwards correspondingly, as shown
in FIG. 8. As explained above, the valve 76 then closes while the
outside air goes around the O-ring 86 to penetrate into the orifice
98 and thus reestablish pressure inside the bottle 2, as
represented by arrows 156 in FIG. 8. As a result, raising the head
60 does not lead to the bottle 2 being raised correspondingly by a
suction cup effect, and a vacuum is maintained in the hoses 72 and
74, and also in the bottle 3.
[0056] Continuing its upward movement, the bar 112 acts via the
rods 130 and 132 to move the body 64 upwards, and then, when the
top faces on the branches 68 come into abutment against the heads
of the screws 92, it moves the base 78 upwards. The head 60 is thus
driven upwards so as to return to its initial configuration. The
user can then take hold of the bottle 2 and extract it from the
compartment 20.
[0057] FIG. 9 shows a variant of the appliance 1 which differs from
that of FIGS. 1 to 8 only in the shape of its means 160 for moving
each head 60, 62 relative to the case 10, as a replacement for the
means 110. As shown in FIG. 9, these means 160 comprise, for each
compartment 20, 22, a pneumatic actuator 162 having its stationary
portion 164 secured to the case, e.g. to the ceiling wall 16, and
its moving rod 166 secured to the bar 112. The advantage of this
variant is that each actuator 162 can be controlled by the vacuum
pump 6, its stationary portion 164 being connected to the pump via
a specific duct 168 and incorporating a return spring that is not
shown in the figures. In practice, the actuators 162 may
advantageously be actuated under the control of the opening/closing
action of the doors 50 and 52.
[0058] FIGS. 10A and 10B show another variant 170 of the means for
moving each head 60, 62 relative to the case 10 of the appliance 1.
Instead of providing mechanical or pneumatic drive for the bar 112,
as with the above-described means 110 and 160, a compression spring
172 is interposed vertically between the bar 112 and the case 10,
in particular its ceiling 16. This spring 172 is suitable for being
compressed by the user on inserting the bottle 2 in the compartment
20, by bringing the neck 4 of the bottle around the surface 80 of
the head 60. The case 10 is dimensioned so that the user is obliged
to compress the spring 172 in order to be able to place the bottom
of the bottle so that it presses against the floor wall 18. For
this purpose, and as shown in FIG. 10A, the user inserts the bottle
2 into the compartment 20 at an angle inclined relative to the
vertical, and then while moving the bottle upwards to compress the
spring 172, as represented by arrow 174, the user also tilts it
towards the rear, as represented by arrow 176, so as to cause it to
stand up vertically. Once the bottle is thus standing vertically
with its bottom resting on the floor wall 18, the spring 172
expands partially, as represented by arrow 178, while continuing to
keep the head 60 pressed in leaktight manner against the neck 4, as
shown in FIG. 10B.
[0059] The bottle 2 is extracted by acting in the opposite manner,
it being observed that the need to tilt the bottom of the bottle
forwards relative to the neck 4 makes it easier for air to return
into the neck and thus limits the suction cup effect.
[0060] FIGS. 11 to 18 show another example of a household appliance
201 that differs from the appliance 1 described above, and that
also enables two bottles of wine to be conserved, analogous to the
bottles 2 and 3 described above. The appliance 201 comprises a case
210 for storing these bottles, and unlike the case 10 of the
appliance 1, it presents an outside shape that is more complex than
a cylindrical shape, thereby illustrating the multiplicity of case
shapes that are covered by the present invention. Overall, and
using the same conventions for directions as used above for the
case 10, the inside volume of the case 210 is subdivided into a
rear sub-volume (not shown in the figures) and a front sub-volume
that is itself subdivided into a left compartment 220 and a right
compartment 222. As can clearly be seen in FIGS. 12 and 13, the
compartments 220 and 222 are separated by a vertical partition 224
extending from a floor wall 218 to a ceiling wall 216 along an
intermediate partition 214 between the rear and front sub-volumes.
The compartments 220 and 222 are closed on their sides remote from
the partition 224 by respective side walls 226 and 228, and in
front by respective doors 250 and 252. In FIG. 12, the door 252 and
the bottles 2 and 3 are omitted for reasons of visibility.
[0061] Each compartment 220, 222 is associated with a suction head
260, 262 for evacuating a bottle. As in the appliance 1, the heads
260 and 262 of the appliance 201 are identical to each other, the
head 260 being shown in greater detail in FIGS. 15 and 16.
[0062] In the same manner as the compartments 20 and 22 of the
appliance 1, the compartments 220 and 222 are dimensioned to enable
the respective bottles 2 and 3 to gain access thereto and to stand
vertically therein, with their bottoms bearing stably against the
floor wall 218. This floor wall 218 optionally presents an
arrangement that could also be implemented in the appliance 1 and
that consists in shaping the top face of the wall 218 with concave
spherical cap-shaped depressions 218A and 218B associated with the
compartments 220 and 222 respectively. As can be seen clearly in
FIG. 13, each depression 218A, 218B presents an axis of revolution
X.sub.A-X.sub.A, X.sub.B-X.sub.B that is substantially vertical.
The geometrical center C.sub.A, C.sub.B of each depression 218A,
218B is situated in the zone occupied by the neck 4, 5 of the
bottle 2, 3 when it is standing on the floor wall 218. In other
words, the radius of curvature of each depression is substantially
equal to the height of the bottles 2 and 3. In this way, if the
bottle is not put down centrally about the axis X.sub.A-X.sub.A or
X.sub.B-X.sub.B, as shown for the bottle 2 in FIG. 13, then the
bottle bears against the depression 218A, 218B in a manner that is
inclined a little relative to the above-mentioned axis such that
its neck 4, 5 is substantially generally centered on the center
C.sub.A, C.sub.B. Thus, whatever the exact position of the bottle
2, 3 on the depression 218A, 218B, the neck 4, 5 of the bottle
occupies the same position relative to the case 210, so that the
corresponding suction head 260, 262, described in detail below, is
capable of co-operating therewith in effective and reliable manner.
In particular, by providing for the axes X.sub.A-X.sub.A and
X.sub.B-X.sub.B to be substantially in alignment with the
respective central axes Z-Z of the heads 260 and 262, each head can
be pressed against the corresponding bottle in effective manner,
regardless of the exact position of the bottle on the corresponding
depression 218A, 218B.
[0063] As shown in detail in FIG. 16, the head 260 comprises a main
tubular body 264 of substantially vertical longitudinal central
axis Z-Z. In its intermediate portion, the body 264 is provided
internally with a horizontal wall 266 that occupies a diametral
plane of the body. This wall 266 is provided with vertical arms 268
projecting downwards from the bottom face of the wall 266, these
arms 268 being distributed in regular manner around the axis Z-Z.
The top end of the body 264 forms a tube 270 for connection to a
flexible hose 272 having its end remote from the head 260 connected
to a vacuum pump analogous to the vacuum pump 6 described with
reference to the appliance 1. For convenience, this pump is
likewise referenced 6 for the appliance 201, as can be seen in FIG.
15, it being understood that this pump can be arranged in the same
manner as described above for the appliance 1.
[0064] In its main portion the body 264 is provided internally with
a valve 276 analogous to the above-described valve 76.
[0065] The head 260 also includes a base 278 essentially arranged
beneath the body 264 and presenting a generally tubular shape
centered on the axis Z-Z.
[0066] The bottom end of the base 278 is shaped analogously to the
base 78, i.e. as a truncated cone, thereby defining a frustoconical
outside surface 280 centered on the axis Z-Z and diverging towards
the body 264, with the same advantages as those explained above for
the appliance 1.
[0067] The base 278 is provided on the outside with two annular
rims extending around the entire periphery of the base, namely a
bottom rim 282 and a top rim 283. A compression spring 285 is
interposed along the direction of the axis Z-Z between the rim 282
and the wall 266. The rim 283 is adapted to bear downwards against
the free ends of the arms 268, under drive from the spring 285,
thereby tending to move the base 278 downwards relative to the body
264.
[0068] At its bottom end, the base 278 is permanently secured to an
essentially flat gasket 284 centered on the axis Z-Z and at which
the top of the frustoconical surface 280 terminates. Unlike the
gasket 84 of the appliance 1, having its entire top face in contact
with the base 78, substantially all of the top face of the gasket
284 is spaced apart from the base 278, thereby leaving between them
a non-negligible axial space, except at the central portion of the
gasket. In this way, by making the gasket 284 out of elastic
material, the gasket forms a flexible lip suitable for being
deformed to a greater or lesser extend around its periphery by the
top end face of the neck 4, 5 of the bottle 2, 3 when the head 260,
262 is pressed in leaktight manner against the neck. This shaping
of the gasket 284 as a flexible sealing lip enables the heads 260
and 262 to adapt to the various diameters of bottle necks without
degrading the quality of the leaktight contact in operation between
said heads and the bottle necks.
[0069] An O-ring 286 centered on the axis Z-Z is interposed between
the top end face of the base 278 and the wall 266 of the body 264.
In the embodiment shown in the figures, the O-ring 286 is fastened
to the bottom face of the wall 266, being received in a
complementary groove. The O-ring 286 is functionally analogous to
the O-ring 86 of the heads 60 and 62 of the appliance 1.
[0070] In the same manner as the base 78 being movable relative to
the body 64 in the heads 60 and 62 of the appliance 1, the base 278
is movable relative to the body 264 between a low extreme position,
shown in FIG. 16, in which the base and the body are spaced apart
from each other under the action of the compression spring 285, and
a high extreme position (not shown) in which the base and the body
are pressed vertically one against the other with the O-ring 286
interposed between them, thereby sealing the connection between the
bottom opening of the body 264 and the top opening of the base 278.
The valve 276 acts in the same manner as the valve 76: in the
above-mentioned high position, the through central orifices 296 and
298, respectively defined by the body 264 and the base 278, are put
into fluid flow communication through the valve and then form an
air suction passage 300 between the bottom and top ends of the head
260, 262, whereas in the above-mentioned low position, the valve
276 isolates the orifices 296 and 298 hermetically from each other,
thereby closing the passage 300.
[0071] Furthermore, compared with the means 110, 160, or 170 for
moving the heads 60 and 62 in the appliance 1, the appliance 201
has other means 310 for moving each of the heads 260 and 262
relative to the case 210. Each head 260, 262 is thus associated
with a cylindrical housing 312 centered on the axis Z-Z. The body
264 of the head 260 or 262 is located inside the housing 312, being
pressed in abutment against a bottom end internal rim 313 by a
compression spring 336 interposed between the wall 266 of the body
264 and a top end portion of the housing 312. Each housing 312 is
assembled to the case 210 so as to be movable in a vertical
direction. In the embodiment described, each housing 312 is
slidingly received in a vertical sheath 314 secured to the sealing
wall 216. Each sheath presents an inside diameter that matches the
outside diameter of the housing 312, so as to guide the cylinder
effectively as it moves relative to the case 210.
[0072] In addition, at its rear side, each cylinder 312 is
permanently provided with a rack 318 meshing with a toothed wheel
320 carried by the end of a shaft 322 supported by the top side of
the ceiling wall 216. The opposite end of the shaft 322 carries a
toothed wheel 324 meshing with a horizontal rack 326. The rack 326
is supported by the top side of the ceiling wall 216 so as to move
in horizontal translation between front and back. A traction spring
328 is interposed between the rack 326 and a stationary portion of
the ceiling wall 216 so that when the housing 312 is moved
downwards in translation, its movement is transmitted to the spring
328 successively via the wheel 320, the shaft 322, the wheel 324,
and the rack 326, thereby tensioning the spring 328. In other
words, the spring 328 tends to hold the housing 312 mechanically in
a position where it is moved in translation upwards relative to the
case 210.
[0073] In order to keep the housing 312 in a position in which it
has been moved in translation downwards, i.e. in order to counter
the action of the spring 328, the case 210 is provided, for each
housing 312, with a rocker arm 330 having one end 331 inserted by a
compression spring 332 in a complementary notch 334 defined in the
top portion of the housing 312, as can clearly be seen in FIG.
15.
[0074] The appliance 201 is used in a manner that is substantially
analogous to the appliance 1. Below, the description relates more
particularly to the differences in the way the two appliances are
used.
[0075] Initially, it is assumed for example that the compartment
220 is empty, with its corresponding door 250 open. The user places
the bottle 2 manually in the compartment 220, causing it to rest on
the depression 218A, with the neck 4 of the bottle thus being
substantially centered on the center C.sub.A regardless of any tilt
the bottle might have relative to the axis Z-Z, as explained above.
The head 260 and its housing 312 are then configured relative to
the case 210 and the bottle 1 in the manner shown in FIG. 16.
[0076] Thereafter, the user causes the door 250 to take up its
closed position, and then pushes the housing 312 manually downwards
as represented by arrow 350 in FIG. 16. This downward movement in
translation of the housing 312 is transmitted by the spring 336 to
the body 264 of the head 260, the body in turn entraining the base
278 by the downward movement in translation being transmitted by
the spring 285, until said base is pressed against the neck 4 of
the bottle 2, as described in detail above for the head 60 of the
appliance 1.
[0077] The user continues moving the housing 312 downwards until
the end 331 of the arm 330 is inserted in the notch 334 under drive
from the spring 332. The arm 330 thus holds the housing 312 in its
position where it is moved downwardly in translation relative to
the case 210, as shown in FIGS. 11 to 13. The spring 336 compresses
to accommodate the corresponding extra stroke of the housing 312
relative to the base 278.
[0078] By then actuating the vacuum pump 6, the air contained in
the top portion of the bottle 2 is sucked out through the passage
300 so that the bottle is evacuated. In practice, actuation of the
vacuum pump 6 may be controlled in the various manners mentioned
above for the appliance 1.
[0079] When the user desires to consume the wine remaining in the
bottle 2, the user opens the door 250. Advantageously, moving the
door to its open position causes the arm 330 to be disengage
automatically from the notch 334 by means of a cam 338 linked to
the door. If such an arrangement is not provided, then the user
needs to tilt the arm 330 under manual control, e.g. by means of a
button (not shown) that is easily accessible to one of the user's
fingers when the door 250 is open. The spring 328 then relaxes,
driving the housing 312 upwards successively via the rack 326, the
wheel 324, the shaft 322, the wheel 320, and the rack 318. The
appliance 210 is then in the initial configuration described
above.
[0080] Comparing the way the appliances 1 and 201 are used shows
that with the appliance 1, the movement of the heads 60 and 62 is
mechanically coupled to opening and closing the doors 50 and 52,
whereas with the appliance 201, the movement of the heads 260 and
262 is decoupled from the opening and closing of the doors 250 and
252, except concerning possible automatic unlocking of the housing
312 by drive from the optional cams 338.
[0081] FIGS. 17 and 18 show the refrigerator means of the appliance
201 in detail, it being understood that these refrigerator means
could be arranged in the appliance 1 instead of the Peltier element
34. In this embodiment, the refrigerator means are in the form of a
double Peltier element 234. More precisely, two Peltier main bodies
236 and 237 are secured side by side permanently to the partition
214, and they pass through said partition. Each cold front face
238, 239 of the bodies 236 and 237 is fitted with a respective fan
unit 244, 246, the partition 224 being arranged between them.
Advantageously, the hot rear faces 240 and 241 of the bodies 236
and 237 are fitted with a common fan unit 242.
[0082] Using a double Peltier element 234 presents a genuine
advantage in limiting electricity consumption when the two
compartments 220 and 222 need to present different internal
temperatures. Under such circumstances, it may suffice to power
only one of the two bodies 236 and 237 electrically, i.e. the body
that is associated with the compartment that is to have the lower
temperature. The low temperature produced in that compartment then
tends to spread into the other compartment through the partition
224, and by stirring the air with the fan unit 224 or 246 in the
warmer compartment, the temperature desired for that compartment
may be reached without it being necessary to power the
corresponding Peltier element body electrically.
[0083] It is possible to envisage various modifications and
variants for the above-described appliances 1 and 201. By way of
example:
[0084] the doors 50 and 52 or 250 and 252 may present shapes other
than those shown in the figures, while being suitable for being
moved in a variety of ways, it being possible, for example, for
them to be swing doors, lift doors, sliding doors, telescopic
doors, etc.;
[0085] in a simplified version of the appliance 1 or 201, the
appliance need not have its own refrigerator means such as the
Peltier element 34 or the double Peltier element 234, and need not
have its doors 50 and 52 or 250 and 252, so that it does not have
bottle storage compartments; under such circumstances, the
movements of the suction heads 60 and 62 or 260 and 262 are
controlled by actuation taking the place of opening and closing the
doors, in particular by actuating specific control means carried by
the case 10 or 210, the case then presenting the simplified shape
of a bracket for supporting the heads and the means for moving
them;
[0086] in another version, the appliance 1 may be incorporated
inside a cabinet for storing bottles, in particular wine bottles;
the case 10 is then incorporated in a specific zone of the inside
volume of the cabinet, preferably in the optionally curved inside
portion of the door that gives access to said internal volume;
thus, if the door is transparent, the user can see directly and
clearly the or each bottle that has its neck engaged in one of the
suction heads: the vacuum is provided by a pump situated outside
the cabinet, e.g. in a compartment dedicated to the compressor for
the cold circuit of the cabinet, and it is taken to the head by one
or more ducts internal to the cabinet, and located in part in the
hinge region of the door; under such circumstances, the heads are
preferably driven by the vacuum, as in the embodiment of FIG. 9, so
as to avoid providing a supply of electricity in the door of the
cabinet, thereby limiting safety risks associated with an electric
cord being subjected to flexing when the door is opened and closed;
the heads may be connected to the atmosphere either under the
control of the door being open, or by pressing on a button inside
or outside the cabinet;
[0087] in addition to being used for moving the heads 60 and 62 as
in the variant of FIG. 9, the vacuum delivered by the pump 6 may be
used for driving movement of the doors 50 and 52;
[0088] other forms of means 110, 160, and 170 for moving the heads
are possible and may for example comprise actuators, such as an
electrical jack;
[0089] in a variant that is not shown, the flat gasket 84 or the
lip gasket 284 of each suction head may include a gasket
constituted by an inflatable tube that, when deflated, is easily
inserted inside the neck of a bottle while the head is moving
downwards, and that, once inflated, fits in leaktight manner
against the inside periphery of the neck of the bottle; the tube is
inflated by providing a fluid flow connection between the tube and
a cylindrical chamber having an inside volume that is compressed by
a piston, advantageously a piston driven by the vacuum coming from
the pump 6;
[0090] the appliance may also be fitted with a system for
neutralizing each of its heads 60 and 62 so as to enable it to
store, in particular at a cooled temperature, one or more bottles
without evacuating it/them, in particular bottles that have not yet
been opened, it being observed that it is possible to store such
bottles in the appliance 201 without making any additional
arrangements thereto, since it is the user who causes the heads 260
and 262 to move down by acting directly on them;
[0091] the vacuum pump 6 and/or motor drive for the doors 50 and 52
or 250 and 252 may be controlled, in part or entirely, by detectors
for detecting the presence of bottles 2 and 3 in the corresponding
compartments 20 and 22 and/or by detectors for detecting the hand
of the user coming close or going away;
[0092] it is possible to envisage positioning elements other than
the fork 140, such as a defined indentation in the floor wall 18 or
218, such as the depressions 218A and 218B, or a centering V,
etc.;
[0093] the Peltier element 34 may be replaced by other refrigerator
means, such as a system using a compressor, a system for
circulating cold water, an atmospheric refrigeration system, etc.;
in addition, the temperature of the cold air obtained by these
various refrigerator means may either be predetermined, in
particular depending on whether the bottle of wine for cooling
contains a white wine or a red wine, or else it may be set by the
user adjusting a setpoint knob or the like;
[0094] generally speaking, the vacuum pump 6 may be replaced by a
vacuum source, such as a vacuum network;
[0095] the case 10 or 210 could define only a single storage
compartment, and likewise it could equally well delimit three or
even more storage compartments; and/or
[0096] the appliance may incorporate photocells making it possible
to recognize automatically a red wine or a white wine by the
difference in transparency, i.e. not only to detect the presence of
the bottle, but also to adjust the refrigeration temperature
setpoint as a function of the wine.
