Abstract
A refrigerator cabinet having a dividing partition with the top
freezer compartment having an ice piece dispenser in communication
with an upper passageway normally closed by a counterweighted ramp
closure on the underside of the partition while the lower
compartment door has an enclosure including a lower ice piece
passageway forwardly offset from the upper passageway communicating
with an exterior ice service area in the lower door. The lower
passageway is closed by a closure member which when actuated to an
upwardly and rearwardly inclined position engages a follower to
pivot the ramp closure to downwardly and forwardly inclined
position defining a connecting channel between the passageways. The
closure member has delay means to allow all the dispensed ice
pieces time to enter the lower passageway before closing
thereof.

Description
This invention relates to a domestic refrigerator and particularly
to a refrigerator having a partition dividing the cabinet into
upper and lower compartments with an ice piece dispensing
arrangement for delivering ice pieces from a dispenser in the upper
freezer compartment through both the partition and the lower
compartment door to an exterior recessed ice service area in the
door.
It is therefore an object of this invention to provide means in a
refrigerator having a partition dividing the cabinet into upper and
lower compartments with an automatic ice piece dispenser in the
upper compartment for dispensing ice pieces through an upper
passageway in the partition and a forwardly off-set lower
passageway through the lower compartment door wherein the dispenser
may be located in the rear area of the top freezer compartment such
that a pair of oppositely swinging closure members for the
passsageways are moved in sequence to their open positions in
parallel inclined relation by actuator means from an exterior
recessed ice service area in the lower door to define a connecting
channel between the off-set passageways.
It is another object of the present invention to provide an upper
and lower compartmental refrigerator having an ice maker including
an ice piece dispenser in the upper freezer with an ice piece
discharge chute device on the underside of the horizontal divider
partition separating the compartments operative to deliver ice
pieces from an upper passageway in the partition to a forwardly
off-set lower passageway in the lower compartment door whereby the
chute device includes an upper closure member maintained in closed
position by counterweight follower and lever mechanism operative to
pivot the upper closure member to a downwardly and outwardly
inclined open position actuated from an ice service area in the
outer face of the lower compartment door in conjunction with the
pivotal movement of a lower passageway closure member to an
upwardly and inwardly inclined open position arranged in parallel
channel forming relation to the lower closure member and whereby
air operated delay means are provided to retard the closing of the
closure members until all the ice pieces dispensed into the upper
passageway have passed into the lower passageway for dispensing
into the service area.
Further objects and advantages will become more apparent from the
following specification, reference being had to the accompanying
drawings of which:
FIG. 1 is a perspective view of a refrigerator cabinet
incorporating the present invention with the upper and lower
compartment doors shown in an open position;
FIG. 2 is a fragmentary front elevational view of the ice service
area of the present invention incorporated in the outer wall of the
lower compartment door;
FIG. 3 is an enlarged horizontal sectional view taken along line
3--3 of FIG. 2;
FIG. 4 is an enlarged vertical sectional view taken generally along
the line 4--4 of FIG. 2;
FIG. 5 is a perspective view of the underside of the horizontal
partition separating the upper and lower compartments showing the
ice piece dispensing chute unit in closed position;
FIG. 6 is a fragmentary vertical sectional view taken generally
along line 6--6 of FIG. 3;
FIG. 7 is a fragmentary vertical sectional view taken generally
along line 7--7 of FIG. 3.
Referring now to the drawings, especially FIG. 1, there is shown a
refrigerator cabinet 10 having an upper freezing compartment 11 and
a lower fresh-food storage compartment 12. The cabinet includes an
insulated top outer wall 13, insulated side walls 14 and 15, the
inner surfaces of which extend rearwardly from the cabinet front
opening, and having disposed therebetween in the lower compartment
a plurality of shelves 16 and lower storage pans 17 and 18 above
compartment insulated bottom wall 19. The top freezer compartment
11 has an access opening 20 thereto closed by an upper insulated
door 21 while the lower compartment 12 has an access opening 23
closed by main insulated door 24. The lower door 24 includes an
outer sheet metal wall 25 while the inner wall of the door is
provided with an inner door pan 26 preferably of sheet plastic
material such as high impact polystyrene or ABS copolymer. The door
pan 26 is bordered by a peripheral rib 27 having shelves 28
extending between the vertical portions of the rib. A breaker strip
29 of plastic material joins the door outer wall and inner panel.
The inside of the door 24 includes an enclosure 30 positioned with
its top surface 31 in downwardly off-set relation with the upper
face of the rib 27 while its outer side surface is in inwardly
off-set relation with the outer face of the vertical portion of the
rib 27.
As seen in FIG. 4, the upper freezer compartment 11 and the lower
compartment 12 are separated by a horizontal divider or partition
32, filled with foamed resin insulating material 33, providing
upper passageway means 34 in the form of a rectangular cross
section ice piece or ice cube passageway having its entrance 36 in
the upper surface 38 of the partition 32 for receiving ice pieces
from the discharge opening 40 of suitable automatic ice dispensing
means 42, such as the screw conveyor disclosed in U.S. Pat. No.
3,387,743 for example, including a receptacle or bin 44 for
receiving and storing ice pieces produced by an automatic ice maker
positioned thereabove in casing 46. It will be noted that the ice
maker casing 46 and subjacent bin 44 are positioned in their
conventional location in the rearward area of the upper compartment
11 such that applicants' invention can be incorporated in a
conventional refrigerator with a minimal amount of structural
alteration. An example of one type of ice maker suitable for use
with applicants' invention is disclosed in U.S. Pat. No. 3,540,227,
assigned to the assignee of the instant application.
As seen in FIGS. 1 and 4, a guide housing 50 having triangular side
walls 51 joined by a sloping front wall 52 is provided in the upper
compartment whereby the guide 50 encloses the discharge opening 40
of the ice dispensing means 42 and the entrance 36 of the upper
passage 34 to provqde communication of the ice pieces therebetween
upon actuation of the dispenser 42. it will be noted that
applicants' structure allows sufficient space forward of the
dispenser 42 for the upper passageway 34 with minimal interference
with the refrigerated air inlet slots 53 in divider 32. The exit 54
of passageway 34 is provided with a peripheral gasket 56
therearound for sealing engagement by a pivoted ramp closure 58 of
a discharge chute housing, indicated generally at 60 in FIG. 5,
having an inwardly curved rear wall 61 suitably affixed on the
underside of the divider 32. The ramp closure 58 is mounted in the
chute housing by horizontally reciprocating or sliding pivot means
consisting of studs 62 located on either side of the rear edge 63
of ramp closure 58 slidably received in rearwardly extending slots
64 located in opposed relation on respective inner faces of chute
unit side walls 66, 67. In this way the studs 62 are moved to a
location at the rear open ended portion of the slots with the ramp
closure 58 pivoted to its solid line horizontal closed position as
seen in FIG. 4.
Counterweight lever means in the form of a pair of bellcrank levers
68, 69 are pivotally mounted on either side wall 66 and 67 of the
chute housing 60 by respective pivot pins 70, 71 intermediate their
ends. The bellcrank levers are provided with forwardly and
downwardly extending portions 72 and with rearwardly and downwardly
extending portions 73. The side walls 66, 67 each have respective
elongaged arcuate slots or tracks 74 and 75 for reception of the
outer ends of horizontal bail yoke 76 extending through ramp
closure 58 intermediate the forward 65 and rear 63 edges thereof.
Chute follower means in the form of tubular roller 77 is rotatably
supported on a transverse pin 78 joining the lower ends of lever
portions 72 and functions as a counterweight to normally bias the
closure member 58 in its horizontal closed position as shown in
FIG. 4. Stop means in the form of structural crossbrace 79 is also
provided above the follower 78 to integrally join the lower ends of
lever portions 72. The arcuate slots 74 in cooperation with the
bail yoke 76 and slidable studs 62 pivot the closure member 58 to a
predetermined downwardly and outwardly inclined position, shown in
FIG. 4 in phantom lines, which preferably is an angle of about 50
degrees below the horizontal.
FIG. 4 shows the outer wall 25 of lower cabinet door 24 including a
housing member 80 preferably of plastic material located therein
defining a recessed service area 82 for receiving a drinking glass
(not shown) above a liquid overflow tray 83 to receive ice pieces
delivered exteriorly of the cabinet from the ice dispenser 42. The
enclosure 30 is located substantially coextensive with the service
area 82 such that its upper surface 31 is located in vertically
spaced relation a defined distance below the overlying bottom wall
90 of the partition 32. It will be noted that the enclosure 30
extends inwardly into compartment 12 to a position wherein its rear
wall 96 lies in a vertical plane, the extension of which intersects
the divider partition 32 substantially along the forward edge of
the upper passageway exit 54.
The lower passageway 86 is in the form of a downwardly inclined
right angled elbow with its upper entrance 98 located in recessed
portion 100 in horizontal enclosure surface 31 and includes closure
means in the form of an insulated closure member 110 operable when
in its horizontal position to seat on peripheral gasket member 112
to close in a sealed manner the entrance 98 of the lower
passageway. As seen in FIG. 6, the upper wall 114 of door member
110 is shown as sheet metal having downwardly formed flanges
engaging the edges of a bottom panel 115 preferably of plastic
material having hinge means at its outer pivotal edge in the form
of a pair of forwardly extending integral spaced ears 116 having
aligned apertures for receiving a transverse pin 118 the ends of
which are pivotally received in the opposed side walls of recess
100. The closure member 110 hinge means thus allows the member to
swing to an upwardly and rearwardly inclined position, shown in
phantom lines in FIG. 4, in parallel inclined relation to
oppositely swinging closure member 58.
The closure member 110 actuating means includes a pair of arcuate
arms 120, 121 integrally formed on either side of the door panel
115 and extend through an arc of about 90 degrees within the lower
passageway 86 so as to project outwardly beyond the rear wall 122
of the service area 82 for pivotal attachment to spaced parallel
legs 126, 127 of a U-shaped metal actuator 130 movably supported in
service area housing 80. The U-shaped actuator legs 126 and 127 are
slidably received for reciprocal movement in opposed longitudinal
slots 128, 129 formed in the inner face of side walls 132, 133 of
the housing 80.
As seen in FIG. 7 the arcuate arms 120, 121 each has integral
outwardly projecting studs 134, 135 received in vertically oriented
elongated apertures 136, 137 in respective actuator legs 126, 127.
In this way pivotal movement between the arcuate arms and their
associated actuator legs is achieved resulting in the movement of
closure member 110 to its upwardly and rearwardly inclined open
position upon the user pushing in on the U-shaped actuator
operating bar portion 138 suitably affixed to its base 139 such as
by screws 140.
A cover plate 141, suitably affixed on the front of housing 80 as
by screws 142, includes a rectangular bearing 143 for guiding the
reciprocal movement of the actuator 130 while a downwardly
extending lip portion 144 serves to deflect ice pieces into the
service area through the exit 84 of lower passageway 86. A face
plate 146 may be used to provide a decorative finish for the
serivce area including suitable nomenclature thereon to identify
the actuators. As indicated in FIG. 2 the service area could also
include water dispensing means 147 operated by a suitable actuator
148 in a manner disclosed by U.S. Pat. No. 2,786,338, for example.
Further, a horizontally sliding panel 149 could be provided for
tracking movement in upper and lower door guides 151, 152, if
desired, to conceal the service area when not in use.
As seen in FIG. 4 the closure member 110 has a forward free cam
edge 160 downwardly sloped such that upon an initial small upward
movement of the member 110 its cam edge 160 will sequentially
engage the follower roller 77 and overcome the counterbalancing
downward gravity bias of the roller to initiate downward movement
of the closure member 58. Continued upward movement of the member
110 will cause the crossbrace stop member 79 to depress a plunger
161, protruding downward from the under-surface of partition 32,
for upward movement within switch housing 162 to thereby actuate
button 163 of a microswitch 164 which in turn closes a circuit to
energize an electrical drive motor (not shown) of the ice dispenser
42. Thus, the ice dispenser will deliver ice pieces through opening
40 only upon the closure member 110 attaining its upwardly and
rearwardly inclined position (shown in phantom in FIG. 4) defining
the angle of about 50.degree. with the horizontal so as to be in
substantially parallel relation with downwardly and outwardly
inclined closure member 58 and together defining a connecting
channel between the upper and lower vertical off-set passageways 34
and 86 for transfer of the ice pieces therebetween. It will be
noted that cross brace structural member 79 engages the switch
housing 162 lower surface after depressing plunger 161 to thereby
serve as stop means for both upper and lower closure members 58 and
110.
The service area housing 80 has molded in each side wall tubular
cylinder 172, 173 the axes of which extend in parallel horizontal
fashion whereby each encloses a resilient damping or retarding
means in the form of corrugated bellows diaphragm members 176, 177
which can be made of rubber, metal or plastic material each
operable for reciprocable movement within its respective cylinder.
Each bellows member 176, 177 has its outer end affixed to its
outermost fold juncture by respective encircling rings 178, 179 of
L-shaped brackets 182, 183 suitably attached to actuator legs 126,
127 while the inner ends of each bellows are anchored by means of
concentric restricted inner openings 184, 185 which releasably
engage the innermost fold juncture of its respective bellows in
snap-in fashion.
As seen in FIG. 3 each bellows has a reduced connector 186, 187
which sealingly receives therein an associated flexible tube 188,
189, the opposite ends of which are sealingly connected to valve
means 190 in the form of a common valve chamber 191 having opposed
side inlets 192, 193 positioned symmetrically between the parallel
axes of tubes 172, 173 within embossment 194. The valve includes a
circular disc 195 which is adapted to close the valve outlet port
196 and to cut off communication between the interior of each of
the bellows and the atmosphere. The valve disc 195 is normally
urged inwardly to its seated position by a helical coil spring 198
positioned around valve stem 199 and bearing against the outer end
of the valve chamber 191 and at the face of valve stem plate 200.
The valve chamber 191 has a relatively small air inlet port 202
which allows air to bleed into the chamber 191 and the interior of
each of the bellows.
Thus, in operation when the actuator 130 is depressed by the
operator, both of the bellows 176, 177 are simultaneously operated
causing the air therein to be compressed responsive to the
contraction of the bellows and thereby force air from the valve
chamber 191 through outlet port 196 by overcoming the spring 198
and moving the valve disc 195 out of engagement with its valve seat
to its open position. In this manner the closure members 110 and 58
are radially moved to their inclined open position as explained
above to allow immediate dispensing of ice pieces. After the
release of the actuator and with the valve disc returned by spring
198 to sealingly close the outlet port 196 air will slowly bleed
back into the bellows through the small inlet port 202 allowing the
bellows to slowly expand under the influence of the gravity biased
counterweight follower 77 moving to its normal downward position
resulting in a delayed closing of the closure members 110 and 58.
This delayed closure of the members 110, 58 insures that the
dispensed ice pieces have had sufficient time to clear or pass from
the upper passageway 34 into the lower passageway 86 and not be
caught-up by the closure members to prevent their full return to a
horizontal closed position. It will be noted that the chute housing
side walls 66, 67 cooperate with the opened closure member 58 to
form a discharge chute and properly direct the ice pieces into the
entrance of the lower passageway and prevent the ice pieces from
exiting into the lower compartment.
While the embodiment of the present invention as herein disclosed
constitutes a preferred form, it is to be understood that other
forms might be adopted.
