Abstract

A condenser assembly for a refrigerator includes a condenser arranged in a frame. The condenser is configured for a flow of a refrigerant therethrough. The frame has at least one evaporation tray that is arranged above the condenser and one evaporation tray that is arranged below the condenser.

Claims

1. A condenser module for a refrigeration appliance, the condenser module comprising:

a frame;

a condenser arranged on the frame, the condenser being configured for a flow of a refrigerant therethrough; and

a plurality of evaporation trays including at least an upper evaporation tray supported via the frame above the condenser and a lower evaporation tray supported via the frame below the condenser, wherein the upper evaporation tray has an overflow via which water passes from the upper evaporation tray into the lower evaporation tray, the frame having

a side wall extending between the upper evaporation tray and the lower evaporation tray, the side wall having a surface facing the condenser, wherein the overflow cooperates with the surface of the side wall to form a flow path guiding water from the overflow across the surface of the side wall and into the lower evaporation tray, the side wall conducting a stream of air through the condenser.

2. The condenser module as claimed in claim 1, wherein a drip edge lying above the lower evaporation tray forms a portion of the flow path on the side wall.

3. The condenser module as claimed in claim 1, wherein the condenser is connected in series with a refrigerant line running through at least one of the evaporation trays.

4. The condenser module as claimed in claim 1, wherein at least the lower evaporation tray has a latching element for locking engagement with the condenser.

5. The condenser module as claimed in claim 1, wherein the upper evaporation tray is held in a releasable and removable manner on a structure connected to the lower evaporation tray.

6. The condenser module as claimed in claim 1, wherein the frame has a front wall with an opening in which is arranged an impeller of a fan.

7. The condenser module as claimed in claim 6, wherein the opening in the front wall is configured with a nozzle geometry having a portion with a first cross section and another portion with a relatively smaller cross section and positioned intermediate the portion with the first cross section and the condenser.

8. The condenser module as claimed in claim 6, wherein the impeller of the fan is disposed in the opening in the front wall.

9. The condenser module of claim 1,

wherein the side wall includes a drip edge disposed above the lower evaporation tray, the drip edge preventing the water from flowing down the side wall beyond the drip edge, and the drip edge forming part of the flow path for guiding the water from the upper evaporation tray into the lower evaporation tray.

10. The condenser module as claimed in claim 1, wherein the condenser is a wire tube condenser with a plurality of heat exchanger elements, which are connected in series and arranged to form a plurality of planes.

11. The condenser module of claim 10, further comprising:

a first stabilization element for stabilizing the plurality of heat exchanger elements,

the first stabilization element including means for abutting a portion of the side wall and preventing the stream of air through the condenser from flowing between a portion of the first stabilization element and a portion of the side wall.

12. The condenser module of claim 11, further comprising:

a second stabilization element for stabilizing the plurality of heat exchanger elements,

the second stabilization element including second means for abutting a portion of a recess of a refrigeration appliance and preventing the stream of air through the condenser from flowing between a portion of the first stabilization element and a portion of the side wall.

13. The condenser module of claim 10, further comprising:

a first stabilization element for stabilizing the plurality of heat exchanger elements,

the first stabilization element including a first projection abutting a portion of the side wall and preventing the stream of air through the condenser from flowing between a portion of the first stabilization element and a portion of the side wall.

14. The condenser module of claim 13, wherein the first projection has a contour matching a contour of the portion of the side wall.

15. The condenser module as claimed in claim 10, wherein the condenser includes a first stabilization element with a plurality of grooves, and wherein each respective edge of the plurality of heat exchanger elements in each of the plurality of planes engages in a respective groove of the plurality of grooves of the first stabilization element.

16. The condenser module as claimed in claim 15, wherein the plurality of heat exchanger elements are arranged one above another.

17. The condenser module as claimed in claim 16, wherein the first stabilization element is a columnar stabilization element having a face either touching the side wall of the frame or projecting into a recess of the refrigeration appliance accommodating the condenser module therein.

18. The condenser module as claimed in claim 16, wherein the first stabilization element includes pairs of grooves lying opposite one another and at the same height with respect to one another, wherein sections of piping of each heat exchanger element engage in a pair of grooves.

19. The condenser module as claimed in claim 16, wherein the condenser includes a second stabilization element, and

wherein the first stabilization element and the second stabilization element are on opposite sides of the condenser.

20. The condenser module as claimed in claim 16, wherein the first stabilization element is formed from foamed plastic that is one of a plastic that is a foamed polystyrene and a plastic that is not a foamed polystyrene.

21. A refrigeration appliance comprising:

a compartment for retaining an item to be cooled; and

a condenser module having a frame, a condenser arranged on the frame, the condenser being configured for a flow of a refrigerant therethrough, and

a plurality of evaporation trays including at least an upper evaporation tray supported via the frame above the condenser and a lower evaporation tray supported via the frame below the condenser, wherein the upper evaporation tray has an overflow via which water passes from the upper evaporation tray into the lower evaporation tray, the frame having a side wall

extending between the upper evaporation tray and the lower evaporation tray, the side wall having a surface facing the condenser, wherein the overflow cooperates with the surface of the side wall to form a flow path guiding water from the overflow across the surface of the side wall and into the lower evaporation tray, the side wall conducting a stream of air through the condenser.

22. The refrigeration appliance as claimed in claim 21 further comprising damping elements, wherein the condenser module is secured in a compressor recess on a rear wall of the refrigeration appliance and the damping elements are located between the condenser module and the refrigeration appliance for assisting with securement of the condenser module in position.
