Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with various embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, method, or functional changes made by those skilled in the art according to these embodiments are included in the protection scope of the present invention.

[0019] Such as figure 1 As shown, the direct cooling refrigerator according to one embodiment of the present invention includes a main refrigeration cycle system and a defrosting control system. The main refrigeration cycle system is sequentially connected with a compressor 1 , a condenser 2 , a capillary tube 3 of the main refrigeration cycle, an evaporator 4 in the freezing chamber, and a refrigerating and refrigerating evaporation tube 5 according to the flow direction of the refrigerant. The defrosting control system includes a defrosting refrigeration cycle system, a first switch device 6 and a se...

Abstract

The invention provides a method for controlling the defrosting system of a direct cooling refrigerator, comprising the following steps: starting the main refrigeration cycle system, at this time the first switch device is connected to the compressor and the condenser, and the second switch device is connected to the compressor and the refrigerating Refrigeration evaporator tube; according to the degree of frosting, judge whether to defrost; if so, start the defrost thermostat, the defrost thermostat switches the first switch device to connect the compressor and the freezer evaporator, and the second The switching device is switched to connect the compressor and the defrosting refrigeration evaporator tube, thereby starting the defrosting refrigeration cycle system. The present invention realizes switching between the main refrigeration cycle system and the defrosting refrigeration cycle system through the switching of the first and second switch devices, so that the freezing chamber realizes automatic defrosting.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to a method for controlling a defrosting system of a direct cooling refrigerator. Background technique [0002] At present, there are two ways of cooling refrigerators: direct cooling and air cooling. The two refrigeration methods have their own advantages and disadvantages. The direct cooling refrigerator is easy to frost, and the food is not easy to dry and smell; the air-cooled refrigerator does not frost, but the food is easy to dry and smell. For the frosting problem of direct cooling refrigerators, the existing defrosting technology generally uses automatic compensation heating wires to defrost the refrigerator compartment, while the freezer compartment requires users to defrost manually periodically. Manual defrosting is time-consuming and laborious, and has become an annoyance to many users. Contents of the invention [0003] The object of the present invention is ...
