Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

Referring to FIG. 1 , it is a schematic structural diagram of a refrigerator provided in an embodiment of the present invention under the first preferred embodiment. An embodiment of the present invention provides a refrigerator 10 , which includes a box body and a box door, and the box body is provided with an article accommodating cavity 11 . The article accommodating cavity 11 may be divided into a plurality of storage compartments, such as a refrigerating compartment and/or a freezing compartment, for storing articles with fresh-keeping or freezing requirements.

The refrigerator 10 further includes a refrigeration system for performing a refrigeration operation of the refrigerator. It should be noted that, the refrigerator performs a refrigeration operation through the refrigeration system to provide cold energy and transmit it to the storage compartment, so as to maintain the storage compartment in a constant low temperature state. Specifically, the refrigeration system of the refrigerator according to the embodiment of the present invention is composed of components such as a compressor, a condenser, a drying filter, a capillary tube, an evaporator, and the like. The working composition of the refrigeration system includes a compression process, a condensation process, and a throttling process. and evaporation process.

Among them, the compression process is: plug in the power cord of the refrigerator, and when the box has a cooling demand, the compressor starts to work, and the low-temperature, low-pressure refrigerant is sucked by the compressor, and is compressed into high-temperature, high-pressure refrigerant in the compressor cylinder. The superheated gas is discharged into the condenser; the condensation process is: the high-temperature, high-pressure refrigerant gas dissipates heat through the condenser, the temperature continues to drop, and is gradually cooled to normal temperature, high-pressure saturated vapor, and further cooled to saturated liquid. If it drops further, the temperature at this time is called the condensing temperature. The pressure of the refrigerant in the entire condensation process is almost unchanged; the throttling process is: the saturated refrigerant liquid after condensation is filtered by the drying filter to remove moisture and impurities, and then flows into the capillary tube, through which throttling and depressurization are performed, and the refrigerant changes. It is normal temperature, low pressure wet vapor; the evaporation process is: then start to absorb heat in the evaporator for vaporization, which not only reduces the temperature of the evaporator and its surroundings, but also turns the refrigerant into a low temperature, low pressure gas. The refrigerant from the evaporator is returned to the compressor again, and the above process is repeated to transfer the heat in the refrigerator to the air outside the box, thereby achieving the purpose of refrigeration.

Further, an adjustable shelf system 12 and a door switch detection device 13 are also provided inside the box. The adjustable shelf system 12 includes an adjustable shelf and a drive mechanism for driving the adjustable shelf to ascend or descend. It is composed of components such as the support of the leveling frame. Through the adjustable shelf system, the user can flexibly control the adjustable shelf to ascend or descend to a suitable height to meet the demand for the storage volume of the items. The door switch detection device 13 is used to detect the working state of the box door, and the working state is an open state or a closed door state.
