Abstract

A refrigeration appliance includes a water pipe inside the refrigeration appliance. A collecting tray collects leakage water and an empty conduit conducts the leakage water from the water pipe inside the empty conduit to the collecting tray.

First claim

The invention claimed is:

1. A refrigeration appliance, comprising:
a water pipe inside the refrigeration appliance;
an evaporation tray;
a valve housing;
a collecting tray disposed in said valve housing for collecting leakage water, said collecting tray including an overflow for diverting the leakage water to said evaporation tray;
a function valve disposed in said valve housing for controllably dispensing water; and
an empty conduit for conducting the leakage water from said water pipe inside said empty conduit to said collecting tray.

2. The refrigeration appliance according to claim 1 , which further comprises a refrigeration appliance wall, and foam disposed in said wall, said empty conduit being incorporated by said foam in said wall.

3. The refrigeration appliance according to claim 1 , wherein said evaporation tray is disposed below said valve housing.

4. The refrigeration appliance according to claim 1 , which further comprises a compressor, said evaporation tray being disposed in thermal contact with said compressor.

5. The refrigeration appliance according to claim 1 , wherein said valve housing includes a connector for said empty conduit.

6. The refrigeration appliance according to claim 1 , which further comprises:
a water supply connection; and
an inlet hose connected to said water supply connection, said inlet hose including an outer hose and an inner hose;
said valve housing having a connection for said inlet hose.

7. The refrigeration appliance according to claim 6 , which further comprises a safety valve for shutting off said water supply connection.

8. The refrigeration appliance according to claim 1 , wherein said collecting tray is integrated in said valve housing.

9. The refrigeration appliance according to claim 1 , wherein said valve housing includes a leakage detection device for detecting leakage in a water circuit.

10. The refrigeration appliance according to claim 9 , wherein said leakage detection device includes a micro switch for interrupting a power supply in an event of a detected leak.

11. The refrigeration appliance according to claim 10 , wherein said leakage detection device includes a float for actuating said micro switch.

12. The refrigeration appliance according to claim 6 , wherein said valve housing includes a non-return valve disposed between said connection for said inlet hose and said function valve.

13. The refrigeration appliance according to claim 1 , wherein said evaporation tray is formed of a thermally conductive material.

14. The refrigeration appliance according to claim 1 , wherein said water pipe is disposed inside said empty conduit.
