HOUSEHOLD APPLIANCE, IN PARTICULAR REFRIGERATION DEVICE
A household appliance, in particular a refrigeration device, in which ice bodies can be made of supplied water, includes a hose and/or tube assembly for supply of water to a receiving container, and a valve connected to the hose and/or tube assembly and constructed to release or suppress the water supply to the receiving container. The hose and/or tube assembly has zones in which a physical condition changes, wherein the valve is disposed in the hose and/or tube assembly in a region which has not yet encountered a change in the physical condition after water has been supplied into the hose and/or tube assembly.

The present invention relates to a household appliance, in particular a refrigeration device, in which ice pieces can be produced from supplied water, having a hose and/or tube assembly for supplying the water to a receiving container, and having a valve which is connected to the hose and/or tube assembly and by actuation of which a delivery of water to the receiving container can be released or suppressed.
In the construction of a household appliance of the aforementioned type, also described as an ice maker, a conventional design, as shown schematically in
After a relatively short period of operating the household appliance depicted schematically in its basic construction in
As a result of this discovery, using a test setup corresponding to the layout shown in
The object of the invention is therefore to demonstrate a way in which it can be ensured in the case of a household appliance, and in particular of a refrigeration device of the type described in the introduction, in a relatively simple manner that no fine particle deposits occur in the valve, leading to the described operational malfunctions.
According to the invention the above-cited object is achieved in the case of a household appliance, and in particular of a refrigeration device of the type described in the introduction, in that in the case of a hose and/or tube assembly passing through zones having different physical conditions, in particular having different temperatures and/or different water pressures and/or different active electromagnetic fields, the valve is inserted in the region of the hose and/or tube assembly which after the supply of water into the hose and/or tube assembly, remains without any alteration and/or change in the physical conditions.
The invention provides the advantage that solely by way of an altered placement of the valve as opposed to the arrangement according to
At this point it should be pointed out that in household washing machines it is in fact usual for a controllable inlet valve to be disposed in the respective water intake area. In the hose and/or tube assembly connected directly after said water intake area, however, there exists in practice only one and the same physical condition with regard to temperature or pressure of the supplied water or with regard to the electromagnetic field present. In that application there is therefore no hose and/or tube assembly passing through zones having different physical conditions.
A filter, in particular a fine particle filter, is beneficially disposed upstream of the valve in the hose and/or tube assembly on the input side. This advantageously enables otherwise occurring fine particle deposits to be prevented as far as possible.
Preferably the filter is an activated-carbon filter or a fabric filter. The advantage in this case is that relatively easily obtainable filters can be utilized.
The invention is explained by way of example below with reference to drawings, in which:

Claims
1-4. (canceled)
5. A household appliance, comprising:
- a hose and/or tube assembly for supply of water to a receiving container, said hose and/or tube assembly having zones in which a physical condition changes; and
- a valve constructed to release or suppress a delivery of water to the receiving container, said valve being disposed in the hose and/or tube assembly in a region which has not yet encountered a change in the physical condition after water has been supplied into the hose and/or tube assembly.
6. The household appliance of claim 5, constructed in the form of a refrigeration device in which ice pieces can be produced from supplied water.
7. The household appliance of claim 5, wherein the physical condition is at least a member selected from the group consisting of water temperature, water pressure, and active electromagnetic field.
8. The household appliance of claim 5, further comprising a filter disposed upstream of the valve in the hose and/or tube assembly.
9. The household appliance of claim 8, wherein the filter is a fine particle filter.
10. The household appliance of claim 8, wherein the filter is an activated-carbon filter.
11. The household appliance of claim 8, wherein the filter is a fabric filter.
