Embodiment Construction

[0021] figure 1 A refrigerator of a domestic refrigeration appliance with a freezer compartment 1 and a standard refrigerator compartment 2 is shown. The compartments 1 , 2 are assigned an evaporator 3 or 4 . The injection points 5 , 6 of the evaporators 3 , 4 are each connected to the output of a bistable magnetic valve 7 . The output of the evaporator 4 of the standard refrigerator compartment 2 is connected to the input of the evaporator 3 of the freezer compartment 1 so that together with the evaporator 4 the evaporator 3 is also always cooled. In the evaporator 3 separate lines as far as possible can be provided for the refrigerant injected at the injection point 5 and for the refrigerant originating from the evaporator 4 , which only meet each other near the output of the evaporator 3 , Alternatively, essentially a single line can be provided at the evaporator 3 , into which line the refrigerant flows from the evaporator 4 directly after the injection point 5 .

Abstract

The invention relates to a refrigeration device for a combination refrigerating appliance such as a household refrigerator-freezer combination, comprising a condenser (8) and at least two evaporators (3, 4) which are connected in parallel circuitry to an electrically controlled, multistable selector valve (7) and can be selectively supplied with coolant via the selector valve (7). According to the invention, a series circuit of a first current-controlled switch (18; 19) having PTC resistor characteristics and of the selector valve (7) is connected electrically parallel to the condenser (8).

Description

technical field [0001] The invention relates to a refrigerator for a combined domestic refrigeration appliance, ie for a refrigeration appliance having at least two storage compartments which can be kept at different temperatures, and to the refrigeration appliance itself. Background technique [0002] Different types of refrigerators are known for such combined refrigeration equipment. In the simplest type, the compressor, freezer compartment evaporator and standard refrigerated compartment evaporator are connected in series in a single refrigerant cycle. Refrigerators of this type enable a very simple control in that an electromagnetic switch controlled by a temperature sensor, such as a bimetallic element, is applied to one of these compartments, as in conventional refrigeration equipment with a single compartment, in order to The supply circuit of the compressor is closed when the temperature in the compartment exceeds a predetermined limit value. Such refrigerators on...
