Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Embodiments of the present invention provide a refrigerator 10 that includes at least one storage compartment, such as a refrigerator compartment and/or freezer compartment, for storing items that have a fresh or frozen demand. The refrigerator further includes a refrigerating system for performing a refrigerating operation of the refrigerator.
The refrigerator performs a refrigerating operation through the refrigerating system, and provides cold energy to be transferred into the storage chamber so as to maintain the storage chamber in a constant low-temperature state. Specifically, the refrigerating system of the refrigerator provided by the embodiment of the invention comprises a compressor, a condenser, a drying filter, a capillary tube and an evaporator, and the working composition of the refrigerating system comprises a compression process, a condensation process, a throttling process and an evaporation process.
The compression process comprises the following steps: when the contact of the temperature controller is connected, the compressor starts to work, the low-temperature and low-pressure refrigerant is sucked by the compressor, compressed into high-temperature and high-pressure overheat gas in the compressor cylinder and discharged to the condenser; the condensation process is as follows: the high-temperature and high-pressure refrigerant gas is radiated by a condenser, the temperature is continuously reduced, the refrigerant gas is gradually cooled into normal-temperature and high-pressure saturated vapor, the saturated vapor is further cooled into 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 unchanged in the whole condensation process; the throttling process is as follows: the condensed refrigerant saturated liquid is filtered by a drying filter to remove moisture and impurities, and then flows into a capillary tube, throttling and depressurization are carried out through the capillary tube, and the refrigerant is changed into wet vapor at normal temperature and low pressure; the evaporation process is as follows: the subsequent vaporization begins by absorbing heat within 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 process is repeated, so that the heat in the refrigerator is transferred to the air outside the refrigerator, and the purpose of refrigeration is achieved.
Referring to fig. 1, a schematic structure of a refrigerator according to an embodiment of the present invention is shown in a preferred embodiment. In the embodiment of the present invention, the storage chamber of the refrigerator 10 further includes a vacuum storage chamber 11 for storing food materials, medicines, and the like.

The controller 15 is respectively connected with the refrigerating system 12, the vacuumizing system 13 and the heating system 14, and is used for controlling the operation of the above systems, so that the vacuum storage chamber can form a low-temperature drying environment, and a user can store dry food materials conveniently.

Then, the vacuumizing system 13 is started to vacuumize the vacuum storage chamber 11 so as to suck redundant air and steam in the vacuum storage chamber 11, and the heating system 14 is controlled to perform heating operation on the vacuum storage chamber 11, so that sublimation of ice in the food stored in the vacuum storage chamber 11 is accelerated, and the indoor humidity of the vacuum storage chamber 11 is reduced.
