Problems solved by technology

In the case of a slide valve there is the danger that the slide valve will freeze on the wall surface delimiting the air passage opening and thus be unable to perform its task at least temporarily
In a suitably structured flap, although the problem of freezing can be reduced, this flap has the disadvantage that in order to turn it over it requires a considerable depth of space, which takes up the effective space of the storage room
Although it is conceivable to reduce this space requirement by replacing a single wide flap with multiple narrow flaps, this involves durability of the refrigeration appliance and increases its manufacturing costs

Embodiment Construction

[0025] figure 1 with 2 A three-dimensional exploded view of a structural component is shown respectively. The structural component is used to be assembled on a channel or in a channel of the intermediate wall between the storage chamber and the evaporator chamber of a frost-free refrigeration appliance, preferably directly assembled in The bottom of the storage compartment cover is used to form an air through hole with an adjustable cross section. figure 1 More positive and figure 2 The structural components are shown more to the back. The titles of the front and back are randomly chosen here. The structural components can be assembled in the middle wall using the front face facing the evaporator chamber and the back face facing the storage chamber, and vice versa, but for the embodiment shown here, it is preferably arranged by the back face facing the storage chamber.

[0026] The structural component is assembled by a substantially flat cylindrical shell-like element 1 open ...

Abstract

The invention relates to a no-frost refrigerator wherein a control element (13) is arranged in an opening (3) for the through-passage of air in a separating wall between the storage chamber and the refrigeratory chamber. Said control element can be displaced between positions in which it covers the free cross-section of the opening (3) for the through-passage of air to different extents. The control body (13) can be rotated about an axis which is perpendicular in relation to the separating wall. The opening (3) for the through-passage of air can be formed in a shell (1) which is part of the separating wall.

Description

Technical field [0001] The invention relates to a frost-free refrigeration appliance. This kind of refrigeration appliance includes a storage room for accommodating refrigerated items and an evaporator room in a heat-insulating shell in a common way, an evaporator is arranged therein and the evaporator room is connected to the storage room through an air channel . In order to cool the storage compartment, air is circulated between the two compartments through an air channel. Separating the storage compartment from the evaporator compartment allows the evaporator to be defrosted when needed, and this does not necessarily lead to heating of the storage compartment. Background technique [0002] In order to adjust the intensity of air exchange between the evaporator room and the storage room, and to suppress the air exchange as completely as possible when defrosting the evaporator, there is usually a regulating body in the air passage of this type of equipment, which can be differen...
