Abstract

A refrigeration device including a heat-insulated housing, which contains a storage compartment, a water tank, a fan for propelling a stream of cold air that passes through an evaporator and a distribution unit for the controlled distribution of the stream of cold air along at least two circulation paths, the first of which is in closer thermal contact with the water tank than the second.

First claim

The invention claimed is:

1. A refrigeration appliance comprising:
a heat-insulating housing;
a storage compartment for refrigerated items, the storage compartment being located in the heat-insulating housing;
a water reservoir;
a blower for propelling a cold air stream sourced from an evaporator; and
a distributor device, the distributor device being operable to distribute the cold air stream in a controlled manner between at least two circulation paths with a first circulation path of the circulation paths being in closer thermal contact with the water reservoir than a second circulation path of the circulation paths,
wherein the water reservoir is disposed outside of the storage compartment and an upstream section of the first circulation path is a duct that runs via the water reservoir, and
a downstream section of the first circulation path is configured to return the cold air stream to the evaporator without disbursing the cold air stream throughout the storage compartment.

2. The refrigeration appliance according to claim 1 , wherein the second circulation path includes a plurality of apertures configured to distribute cooling air in the storage compartment.

3. The refrigeration appliance according to claim 1 , wherein the duct is insulated from the storage compartment.

4. The refrigeration appliance according to claim 1 , further comprising a carcass and a door, wherein a first portion of the duct runs through the carcass and a second portion of the duct runs through the door.

5. The refrigeration appliance according to claim 4 , wherein the first portion and the second portion are sealingly engaged with one another when the door is in a closed position and disengaged when the door is in an open position.

6. The refrigeration appliance according to claim 1 , wherein all of the first circulation path is insulated from the storage compartment.

7. A refrigeration appliance comprising:
a heat-insulating housing including a carcass and a door;
a storage compartment for refrigerated items, the storage compartment being located in the heat-insulating housing;
a water reservoir;
a blower for propelling a cold air stream sourced from an evaporator; and
a distributor device, the distributor device being operable to distribute the cold air stream in a controlled manner between at least two circulation paths with a first circulation path of the circulation paths being in closer thermal contact with the water reservoir than a second circulation path of the circulation paths; wherein
the water reservoir is disposed outside of the storage compartment;
an upstream section of the first circulation path is a duct that runs via the water reservoir;
a first portion of the duct runs through the carcass;
a second portion of the duct runs through the door; and
a portion of the second circulation path runs through the door.

8. The refrigeration appliance according to claim 7 , wherein the second circulation path includes a plurality of apertures configured to distribute cooling air in the storage compartment.

9. The refrigeration appliance according to claim 7 , wherein the duct is insulated from the storage compartment.

10. The refrigeration appliance according to claim 7 , wherein the first portion and the second portion are sealingly engaged with one another when the door is in a closed position and disengaged when the door is in an open position.

11. The refrigeration appliance according to claim 7 , wherein a downstream section of the first circulation path is configured to return the cold air stream to the evaporator without disbursing the cold air stream throughout the storage compartment.

12. A refrigeration appliance comprising:
a heat-insulating housing;
a storage compartment for refrigerated items, the storage compartment being located in the heat-insulating housing;
a water reservoir;
a blower for propelling a cold air stream sourced from an evaporator; and
a distributor device, the distributor device being operable to distribute the cold air stream in a controlled manner between at least two circulation paths with a first circulation path of the circulation paths being in closer thermal contact with the water reservoir than a second circulation path of the circulation paths; wherein
the water reservoir is disposed outside of the storage compartment, an upstream section of the first circulation path is a duct that runs via the water reservoir, and
the second circulation path includes an entrance to the storage compartment on a first side of the storage compartment and an exit from the storage compartment on a second side opposite to the first side.

13. The refrigeration appliance according to claim 12 , wherein the second circulation path includes a plurality of apertures configured to distribute cooling air in the storage compartment.

14. The refrigeration appliance according to claim 12 , wherein the duct is insulated from the storage compartment.

15. The refrigeration appliance according to claim 12 , further comprising a carcass and a door, wherein a first portion of the duct runs through the carcass and a second portion of the duct runs through the door.

16. The refrigeration appliance according to claim 15 , wherein the first portion and the second portion are sealingly engaged with one another when the door is in a closed position and disengaged when the door is in an open position.

17. The refrigeration appliance according to claim 12 , wherein all of the first circulation path is insulated from the storage compartment.
