Description

The present invention relates to a refrigerator with a heating section.

During operation of the refrigerant circuit of a refrigerator, the interior of the refrigerator is cooled. Since a heat conduction takes place between the interior of the refrigerator and the device outer wall of the refrigerator, the device outer wall of the refrigerator is cooled. At a high humidity water can condense on the cooled device outer wall of the refrigerator. In a water condensation on the device outer wall water can run down to the refrigerator and possibly cause damage in the installation room of the refrigerator.

It is the object of the present invention to provide a refrigeration device in which the condensation of water on the device outer wall of the refrigeration device is reduced.

This object is achieved by an article having the features according to the independent claim. Advantageous embodiments are the subject of the dependent claims, the description and the drawings.

According to one aspect, the object according to the invention is achieved by a refrigeration device having an outer device wall, a first heat exchanger, and a heating circuit for heating the device outer wall, wherein the heat cycle comprises a second heat exchanger, wherein the first heat exchanger and the second heat exchanger are thermally coupled, wherein the second Heat exchanger is adapted to receive heat emitted from the first heat exchanger, and wherein the heat circuit comprises a heating section which is thermally coupled to the second heat exchanger and adapted to deliver the heat absorbed by the second heat exchanger to the device outer wall of the refrigerator.

As a result, for example, the technical advantage is achieved that a condensation of water on the device outer wall of the refrigerator is prevented. In order to avoid condensation of water on the device outer wall, refrigerators often require separate heating of the device outer wall of the refrigerator. This heating can be provided conventionally by an extension of the condenser in a refrigerant circuit of the refrigerator, whereby, however, an increased amount of refrigerant in the refrigerant circuit of the refrigerator is required, which leads to an increased resource consumption of the refrigerator.

The device outer wall is the area of the refrigeration device which separates the refrigerator interior from the outside of the refrigerator. The device outer wall comprises in particular the top, back, and / or the long sides of the refrigerator, which complete the refrigerator interior. In particular, the device outer wall does not comprise the front side of the refrigeration device with the opening region of the refrigeration device. Since the user receives access to the refrigeration device interior through the opening region, which can be closed by the refrigeration device door, the front side of the refrigeration device does not close the refrigerator interior when the refrigeration device door is open.

Since only a small amount of heating is required for the reduction of the water condensation on the device outer wall of the refrigeration device, the use of a heating circuit, such as e.g. a thermosyphon or a heating tube, sufficient to achieve sufficient heating of the device outer wall. Hereby, reference is made to a first heat exchanger, e.g. resorted to the condenser of the refrigerant circuit, which gives off heat which is transmitted through the second heat exchanger to the heat cycle. The heating section of the heating circuit in turn outputs the heat absorbed to the device outer wall of the refrigeration device.

The heating section is the area of the heating circuit, that is, for example, the area of a tube of the thermosyphon or the heating tube, which is in thermal contact with the device outer wall. The heating section can be arranged in particular under the surface of the device outer wall.

In addition, the size of the refrigerant circuit of the refrigerator can be reduced, whereby the amount of refrigerant in the refrigerator can be reduced. In addition, the heat circulation effectively removes heat from the first heat exchanger, e.g. Condenser, achieved, which increases the efficiency of the refrigerant circuit.

A refrigeration appliance is understood in particular to mean a domestic refrigeration appliance, that is to say a refrigeration appliance that is used for household management or in the gastronomy sector, and in particular for storing food and / or drinks at specific temperatures, such as, for example, a refrigerator, a freezer, a refrigerated freezer combination, a freezer or a wine fridge.
