Embodiment Construction

[0038] figure 1 The body of the refrigerator or freezer according to the invention is shown at 10 .

[0039] The body can be constructed with a full vacuum insulation system. This is understood to mean that there is a full vacuum insulation 20 between the inside or inner vessel of the device and the outer skin or enclosure. The full vacuum insulation can consist of a film bag in which a core material, such as perlite, is present. The film bag is vacuum-tightly welded on its open side. There is a vacuum in the interior of the film bag, so that the greatest possible thermal resistance is provided in the body. Alternatively or in addition thereto, corresponding full vacuum insulation can be present in the closure element, ie in the door, flap or drawer of the appliance.

[0040] In this case, full vacuum insulation is preferably understood within the scope of the present invention to mean that the body and / or the closure element of the device is formed by a continuous vacuum ...

Abstract

The invention relates to a refrigerator and / or freezer device having at least one body and at least one cooled inner chamber arranged inside said body, said device comprising at least one coolant circuit which cools the inner chamber, and the coolant circuit comprising at least one evaporator, at least one compressor, at least one condenser and at least one throttle, wherein at least one bypass tothe throttle is provided which extends from the condenser directly or indirectly to the evaporator and in which at least one valve is arranged for shutting off said bypass. The evaporator and the bypass are arranged and designed such that a heat pipe effect is present in the bypass and / or in components arranged upstream and / or downstream thereof in the direction of flow.

Description

technical field [0001] The invention relates to a refrigerating and / or freezing device having at least one body and at least one refrigerated interior arranged in the body, wherein the device has at least one refrigerant circuit, The refrigerant circuit serves to cool the interior, wherein the refrigerant circuit has at least one evaporator, at least one compressor, at least one liquefier and at least one throttle or capillary. Background technique [0002] Such refrigerators and / or freezers are known in various embodiments from the prior art. [0003] During the operation of such refrigerators or freezers, icing occurs on the evaporator, which leads to a decrease in the efficiency of the evaporator. It is therefore necessary to defrost the evaporator at certain time intervals or at least when a certain amount of ice is present on the evaporator. [0004] For this purpose, it is known from the prior art to arrange a heating device directly on the evaporator, wherein the he...
