Problems solved by technology

Moreover, existing refrigerators cannot detect such valve leakage
[0006] In addition, the existing refrigerator does not have a structure for removing the garbage attached to the three-way valve when such a valve leakage phenomenon occurs.

Embodiment Construction

[0042] Hereinafter, a refrigerator 10 according to an embodiment of the present invention will be described based on the drawings.

[0043] Fig. 1 is a schematic longitudinal sectional view of a refrigerator 10, which also serves as an explanatory diagram of the electrical system. In addition, FIG. 2 is an explanatory diagram of the freezing cycle of the refrigerator 10.

[0044] First, description will be made based on FIG. 1.

[0045] The cabinet 12 of the refrigerator 10 is provided with a refrigerating compartment 14, a vegetable compartment 16, and a freezing compartment 18 from the upper level. An ice making device not shown in the figure is provided in the freezer compartment.

[0046]A machine room 22 in which the compressor 20 is arranged is provided at the bottom of the back of the freezer compartment 18. In addition, a freezer compartment evaporator (hereinafter referred to as F evaporator) 24 is arranged behind the freezer compartment 18, and a freezer compartment for ...

Abstract

A refrigerator capable of sensing a valve leakage and removing refuse adhered to a valve mechanism. The refrigerator 10 switches via a three-way valve 68 in supplying a refrigerant to an R evaporator 34 and an F evaporator 24. In the case of sensing a valve leakage of the three-way valve 68, the three-way valve 68 is forcibly operated to remove refuse thereby releasing the leakage.

Description

Technical field [0001] The present invention relates to a refrigerator with two evaporators. Background technique [0002] Regarding the recent refrigerators, in order to effectively cool the refrigerator compartment and the freezer compartment separately, some people have proposed a refrigerator with an evaporator for refrigeration and an evaporator for freezing. [0003] In order to efficiently cool the two evaporators with the refrigerant sent from one compressor, a three-way valve is installed in the middle of the refrigerant flow path, and the three-way valve is switched to determine whether the refrigerant is sent to the evaporator for refrigeration or refrigeration. Evaporator. [0004] However, in the refrigerant flow path, garbage may be mixed in during manufacturing and the like. If the garbage is clogged in the three-way valve, the three-way valve will not work properly, and so-called valve leakage will occur. [0005] The so-called valve leakage refers to the phenomen...
