Abstract

A no-frost refrigeration device includes at least one storage chamber for items to be cooled; and an evaporator chamber which is formed by a two-part first housing having first and second housing parts. The first housing part has, at least locally, a flexible surface, and the second housing part has formed thereon a rib which is pressed in a sealing manner into the flexible surface. A ventilator is located in the evaporator chamber for driving air circulation running through the storage chamber and the evaporator chamber.

First claim

The invention claimed is:

1. A no-frost refrigeration device, comprising:
at least one storage chamber for items to be cooled;
an evaporator chamber formed by a two-part first housing having first and second housing parts, said first housing part having, at least locally, a flexible surface, and said second housing part having formed thereon a rib which is pressed in a sealing manner into the flexible surface; and
a ventilator located in the evaporator chamber for driving air circulation running through the storage chamber and the evaporator chamber,
wherein the first housing part is disposed such that a first surface thereof directly opposes a wall of the storage chamber, the first housing part including a second surface opposite the first surface, the second surface at least at least partially delimiting an interior of the evaporator chamber.

2. The no-frost refrigeration device of claim 1 , constructed in the form of a no-frost domestic refrigeration device.

3. The no-frost refrigeration device of claim 1 , wherein the second housing part is an intermediate wall which separates the evaporator chamber from the storage chamber.

4. The no-frost refrigeration device of claim 1 , further comprising a second housing in surrounding relationship to the storage chamber and the evaporator chamber, said flexible surface being mounted on the second housing.

5. The no-frost refrigeration device of claim 1 , wherein the flexible surface is part of a covering element which is mounted internally on a common inner container of the storage chamber and the evaporator chamber.

6. The no-frost refrigeration device of claim 1 , wherein the flexible surface is made from a closed-pore foam material.

7. The no-frost refrigeration device of claim 6 , wherein the closed-pore foam material is expanded polystyrene (EPS).

8. The no-frost refrigeration device of claim 1 , wherein the first housing part is a rigid integral molded part.

9. The no-frost refrigeration device of claim 1 , further comprising an evaporator arranged in the evaporator chamber, said ventilator being arranged downstream from the evaporator, with the rib sealing an intermediate space of the evaporator chamber lying, in a direction of flow, between the evaporator and the ventilator.

10. The no-frost refrigeration device of claim 1 , further comprising a mount provided on the second housing part for the ventilator.

11. The no-frost refrigeration device of claim 1 , wherein the rib extends around a suction aperture of the ventilator formed in the second housing part.

12. A no-frost refrigeration device, comprising:
at least one storage chamber for items to be cooled;
an evaporator chamber formed by first and second housing parts, said first housing part having, at least locally, a flexible surface, and said second housing part having formed thereon a rib which is pressed in a sealing manner into the flexible surface; and
a ventilator located in the evaporator chamber for driving air circulation running through the storage chamber and the evaporator chamber,
wherein one of the first and second housing parts forms an open compartment configured to receive an evaporator and the other of the first and second housing parts forms a cover which closes the open compartment to form the evaporator chamber when the rib is pressed into the flexible surface.

13. The no-frost refrigeration device of claim 12 , constructed in the form of a no-frost domestic refrigeration device.

14. The no-frost refrigeration device of claim 12 , wherein the second housing part is an intermediate wall which separates the evaporator chamber from the storage chamber.

15. The no-frost refrigeration device of claim 12 , further comprising a second housing in surrounding relationship to the storage chamber and the evaporator chamber, said flexible surface being mounted on the second housing.

16. The no-frost refrigeration device of claim 12 , wherein the flexible surface is made from a closed-pore foam material.

17. The no-frost refrigeration device of claim 16 , wherein the closed-pore foam material is expanded polystyrene (EPS).

18. The no-frost refrigeration device of claim 12 , wherein the first housing part is a rigid integral molded part.

19. The no-frost refrigeration device of claim 12 , further comprising an evaporator arranged in the evaporator chamber, said ventilator being arranged downstream from the evaporator, with the rib sealing an intermediate space of the evaporator chamber lying, in a direction of flow, between the evaporator and the ventilator.

20. The no-frost refrigeration device of claim 12 , wherein the rib extends around a suction aperture of the ventilator formed in the second housing part.
