Description
[0001] The invention relates to an arrangement applicable to a
certain type of one-armed batteries provided with a shut-off valve.
In these batteries, elements regulating the amount and ratio of
cold and warm water are built together into a single battery
cartridge. On the bottom plane of this cartridge, inlet and oulet
holes are developed for passing through the cold and warm water,
whereas on its upper part the operating element of the battery arm
is to be found.
BACKGROUND OF THE INVENTION
[0002] It is known that in fields where sterile circumstances are
required, e.g. in hospitals or laboratories, batteries operating
without touching them are used. They function by sensing the
closeness of the user's hand. The operating principle of such
batteries is--independently of their construction--that the amount
and mixing ratio of cold and warm water is adjusted previously by
traditional control elements, and an electromagnetic valve unit is
placed either before them, into the inlet pipe of cold and warm
water, or behind them, into the outlet pipe leading out the mixed
water. The electromagnet is operated by a heat sensor built into
the battery.
[0003] In batteries where the control elements are built together
into a single cartridge, as mentioned above, the manufacturers
tried to arrange the electromagnetic valve unit so that the unified
cartridges applicable in various batteries preserve their unified
character with the electromagnetic valve in them, as well. This was
the principle at designing the battery cartridge according to the
patent No. DE-198.46.720.
[0004] In the bottom part of the housing of this battery, below the
inlet disc, a fixed controlling element, i.e. a mixed water space
is developed connected to the outlet disc of the battery via a side
duct. Under the mixed water space a valve space is situated, which
is connected to the outlet duct by an independent duct passing
beside the mixed water space. The outlet channel of the valve space
opening into the mixed water space is surrounded by an inwardly
directed tube closed by a membrane valve. The membrane valve is
operated by an electromagnet built into the bottom part of the
housing, under the membrane valve.
[0005] It should be noticed that this battery cartridge can be
operated both manually, and by an electromagnet, thus an additional
outlet hole is developed in the inlet disc opening directly to the
mixed water space. The two outlet holes can be controlled
alternatively by the moving control element, i.e. open and close by
the control disc. At manual operation, the outlet hole opening
directly into the mixed water space is open, whereas at
electromagnetic operation the outlet hole connected to the valve
space is open.
[0006] It is seen that this battery cartridge can be built into the
battery as a single unit, but only together with the electromagnet.
Thus, separate battery cartridges should be developed for different
battery types, to which only part of the elements can be
utilized.
OBJECTIVE OF THE INVENTION
[0007] The objective of the present invention is to provide an
arrangement to one-armed batteries provided with an electromagnetic
shut-off valve capable of utilizing the normal battery cartridge
without any change.
BRIEF DESCRIPTION OF THE INVENTION
[0008] Solution of the problem is based on the recognition that the
housing of the battery cartridge described can be divided into two
parts under the inlet disc by a parallel plane. The upper part of
these two parts may be the same as that in normal battery
cartridges, whereas the valve space needed for the operation of the
electromagnet, the valve and the operating electromagnet can be
situated only in the bottom part.
[0009] Thus, the invention relates to an arrangement for one-armed
batteries provided with an electromagnetic shut-off valve in which
the amount and the mixing ration of cold and warm water is
controlled by a battery cartridge. The inlet and outlet holes for
introducing the cold and warm water and letting out the mixed water
are formed on the bottom plane of the battery cartridge, and the
operating element connected to the arm of the battery is situated
in the upper part. It is characteristic for the arrangement that to
the bottom of the battery cartridge a cylindrical socket with two
circumpositioned sealing is fitted. The socket has three channels
connected in a sealed manner to the inlet holes and to the outlet
hole of the battery cartridge, the channel connected to the outlet
hole opens to a window cut into the cylinder jacket between the
seals, whereas the channels connected to the inlet holes connect
the two frontal areas of the socket. In built-in position, the
window is in a water-transporting connection with the outlet duct
of the battery, whereas the flow-through channels communicate with
the cold and warm water network. In the socket, opposite to the
channel leading to the window, a coaxial seating (nest) is
developed to which an electromagnetic valve unit is fixed from the
opposite side of the battery cartridge overriding the window and
fitted to the channel.
[0010] It can be seen that correspondingly to the aim set,
according to the solution comprised in the invention, the battery
cartridge forms a single unit, which may be any normal cartridge,
and another self-contained unit is the assembly ensuring
electromagnetic operation.
[0011] The supporting element of the assembly ensuring
electromagnetic operation is the socket. Similar elements have been
already applied in batteries. Such an element is shown e.g. in the
patent description No. DE-0.780.523. This element is provided with
two tilted, passing bore-holes connected to the inlet holes of the
battery cartridge, whereas a third boring connects the outlet hole
with the window cut into the middle third of the element. This
boring runs from the upper front plane of the element only as far
as the window, and has a uniform diameter in its whole length. The
task of the element is to fix and seal the inlet tubes for cold and
warm water applicable only in a tilted manner due to the design of
the armature body of the battery; thus the socket according to the
invention differs in both its form and its function from this
element.

[0014] FIG. 2 illustrates the top view of the socket according to
the invention,
[0015] FIG. 3 shows the section of the socket along III-III line of
FIG. 2,
[0016] FIG. 4 shows the section of the socket along line IV-IV of
FIG. 2.
DETAILED DESCRIPTION OF THE INVENTION
[0017] FIG. 1 illustrates an embodiment of the battery according to
the arrangement in the present invention. In the armature body 2 of
battery 1, there are a cylindrical space 3 open at the tope and a
space 4 open at the bottom and having a smaller diameter than that
of the cylindrical space 3, divided by a flange 5. The outlet tube
6 of the battery is connected to the cylindrical space 3 from the
side.
[0018] A socket 7, and above it a battery cartridge 8 is placed
into the bottom part of the cylindrical space 3. The cylindrical
space 3 is closed from above by a lid 9, which, at the same time,
clamps the battery cartridge 8 and socket 7 to flange 5. The arm of
the battery is situated above the lid 9, and this arm is fixed to
the operating element of the battery cartridge 8.
[0019] The inlet holes for cold and warm water (not seen in this
Figure), and the outlet hole of the mixed water are to be found at
the bottom of the battery cartridge 8. The battery cartridge 8 has
the traditional arrangement, it is not part of the invention, thus
it is not necessary to describe it in more detail.
[0020] Socket 7, as shown in FIGS. 2, 3 and 4 in more detail, is a
cylindrical body. In the jacket of socket 7, about in its middle, a
window 11 is to be found, which is essentially a seizing limited by
plane surfaces.
[0021] In socket 7, three channels are developed in a manner shown
in FIG. 2. They are arranged so that the openings of channels 13
and 14 being in the upper front surface 12 of the socket 7 are in
coverage with the inlet holes of battery cartridge 8, whereas the
opening of channel 15 is in coverage with the outlet hole 10 of the
cartridge. Channels 13 and 14 are through-holes extending from the
upper front plane 12 to the lower front plane 16. Channel 15 is
also a boring connecting the upper front plane 12 with the window
11. Channels 13, 14 and 15 are not interconnected.
[0022] Opposite to channel 15, on the other side of window 11, a
nest 17 is situated. Nest 17 is a threaded bore having a common
axis with channel 15 and connecting window 11 with the lower front
plane 16. An electromagnetic valve 18 is fixed into nest 17, which
valve overrides window 11 and fits into channel 15. Since the
diameter of the electromagnetic valve unit 18 is larger than that
of channel 15, in channel 15 a section of larger diameter is
developed from the direction of the window 11, to which the
electromagnetic valve unit 18 fits in a sealed manner.
[0023] In the jacket of socket 7, beside window 11, two
circumpositioned grooves 19 are running around having fitting seals
10, in the present case O-rings. The diameter of socket 7 fits the
diameter of the cylindrical space 3.
[0024] In this embodiment the window 11 is situated on socket 7
opposite to the outlet tube 6, thus in the remaining part of the
jacket of body 7, a circumpositioned groove 21 is connected to
window 11, further this groove is also connected to window 11 by
means of a boring 22.
[0025] Between the battery cartridge 8 and socket 7, a sealing disc
23 is placed. This could be prepared from the usual, totally
elastic material, however, in our case it is a plastic disc having
nests at the appropriate places for sealings 24, which are
expediently O-rings. Sealing disc 23 is adjusted to battery
cartridge 8 by claws being on its flange.
[0026] Adjustment of the battery cartridge 8 and socket 7 occurs by
pins (not shown in the Figures), which are fitted into the two
blind holes 25 situated in the upper front plane 12 of socket 7,
and they are also fitted into similar blind holes (not shown) in
the bottom of battery cartridge 8.
[0027] It follows from the above that socket 7 fits sealed to the
cylindrical part 3 of armature body 2 so that the space between the
two seals 20, and thus also window 11, is connected to the outlet
tube 6. Network transport pipes transporting cold and warm water,
26 and 27 are placed into the armature body 2 from below into space
4, said pipes fit sealed to the channels 13 and 14 of socket 7 at
flange 5.
[0028] The electromagnetic valve unit 18 is coupled to a heat
sensor 28, and is connected to an energy source 29. The system also
contains a control circuit, which can be built together either with
the electromagnetic valve unit 18 or with the heat sensor 28.
Energy source 29 is in the present case a 9 Volt battery. Heat
sensor 28 should be situated so that it could sense the hand under
the outlet tube 6. The most appropriate site is the lower part of
outlet tube 6 seen in FIG. 1, but it can also be situated in the
armature body 2, below outlet tube 6.
[0029] The functioning of battery 1 is as follows:
[0030] When out of use, the electromagnetic valve unit 18 keeps
channel 15 closed, thus the mixed water cannot leave battery
cartridge 8, independently whether the control elements of battery
cartridge 8 are in an opened or in closed position.
[0031] As soon as the user holds his/her hand under outlet tube 6,
the electromagnetic valve unit 18 opens as a response for the
signal from the heat sensor 28. If the amount and temperature of
the water mixed by battery cartridge 8 is previously adjusted, then
mixed water corresponding to these requirements will leave through
the outlet hole 10 of battery cartridge 8, which flows from channel
15 of socket 7 via the electromagnetic valve unit 18 to window 11,
from here into the outlet tube 6 of battery 1. If battery cartridge
8 was still closed at the opening of the electromagnetic valve unit
18, or it was not adjusted properly, it can be opened in the
traditional manner, and the temperature of the mixed water can be
adjusted in the same way.
[0032] When the user takes his/her hand away from below the outlet
tube 6, the signal from the heat sensor 28 ceases to exist, and the
electromagnetic valve unit 18 closes.
[0033] Concerning the installation of the battery according to the
invention it should be noticed that in case if flange 5 is of
proper size, and the connecting joints of the electromagnet are not
on its side, but on its ends, socket 7, together with the
electromagnetic valve unit 18 can be pushed into the cylindrical
space 3 on its bottom. For installing the embodiment shown here,
the electromagnet should be taken out from the electromagnetic
valve unit 18, and after pushing in the socket 7, it can be
installed. The valve unit without socket 7 and the electromagnet
makes a complete assembly as well.
