Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The embodiment of the invention provides a refrigerator 10 which comprises a refrigerator body and a refrigerator door, wherein an article accommodating cavity 11 is formed in the refrigerator body. The article receiving chamber 11 may be divided into a plurality of storage compartments, such as a refrigerating compartment and/or a freezing compartment, for storing articles having freshness-retaining or freezing requirements.
The refrigerator 10 further includes a cooling system for performing a cooling operation of the refrigerator. It should be noted that the refrigerator performs a cooling operation by the cooling system, and provides cooling energy to be transmitted to the storage compartment, so that the storage compartment is maintained in a constant low temperature state. Specifically, the refrigeration system of the refrigerator according to the embodiment of the present invention includes a compressor, a condenser, a dry filter, a capillary tube, an evaporator, and the like, and the operation of the refrigeration system includes a compression process, a condensation process, a throttling process, and an evaporation process.
Wherein, the compression process is as follows: the power cord of the refrigerator is plugged, the compressor starts to work under the condition that the box body has a refrigeration requirement, a low-temperature and low-pressure refrigerant is sucked by the compressor, and is compressed into high-temperature and high-pressure superheated gas in a cylinder of the compressor and then is discharged into the condenser; the condensation process is as follows: the high-temperature and high-pressure refrigerant gas is radiated by the condenser, the temperature is continuously reduced, the refrigerant gas is gradually cooled to be normal-temperature and high-pressure saturated vapor and further cooled to be saturated liquid, the temperature is not reduced any more, and the temperature at the moment is called as condensation temperature. The pressure of the refrigerant is almost constant throughout the condensation process; the throttling process is as follows: the condensed refrigerant saturated liquid flows into a capillary tube after being filtered by a drying filter to remove moisture and impurities, throttling and pressure reduction are carried out through the capillary tube, and the refrigerant is changed into normal-temperature low-pressure wet vapor; the evaporation process is as follows: the subsequent vaporization begins by absorbing heat in the evaporator, not only reducing the temperature of the evaporator and its surroundings, but also turning the refrigerant into a low temperature, low pressure gas. The refrigerant from the evaporator returns to the compressor again, and the above processes are repeated to transfer the heat in the refrigerator to the air outside the refrigerator, thereby achieving the purpose of refrigeration.
Further, an adjustable shelf system 12 and a door switch detection device 13 are arranged inside the box body. The adjustable shelf system 12 comprises an adjustable shelf and a driving mechanism for driving the adjustable shelf to ascend or descend, wherein the driving mechanism comprises a driving motor, a guide rail fixed in the article accommodating cavity, a supporting piece for supporting the adjustable shelf and the like.
