The refrigerator further comprises a refrigeration cycle system, wherein the refrigeration cycle system is installed on the refrigerator body 1 and is used for providing cool air for the storage chamber 122 so that the storage chamber 122 forms a low-temperature environment to store articles; the refrigeration cycle generally includes a compressor, a condenser, a dry filter, a throttle device, an evaporator, etc. in communication with a refrigerant pipe, and the operation of the refrigeration cycle includes a compression process, a condensation process, a throttle process, and an evaporation process.

The compression process is as follows: after the power line of the refrigerator is inserted, the compressor is opened to work under the condition that the contact of the temperature controller is connected, the low-temperature low-pressure refrigerant from the evaporator is sucked by the compressor, compressed into high-temperature high-pressure refrigerant gas by the action of the compressor and then discharged into the condenser.

The condensation process is as follows: the high-temperature and high-pressure refrigerant gas is cooled by the condenser to dissipate heat, the temperature is reduced, and the refrigerant gas is gradually cooled into normal-temperature and high-pressure refrigerant saturated vapor and is cooled into refrigerant saturated liquid.

The throttling process is as follows: the condensed saturated liquid and liquid of the refrigerant are filtered by a drying filter to remove moisture and impurities, and then flow into a throttling device, throttling and depressurization are carried out by the throttling device, and the refrigerant is changed into wet vapor at normal temperature and low pressure.

The evaporation process comprises the following steps: the wet vapor with normal temperature and low pressure enters the evaporator, and absorbs heat to gasify, so that the temperature of the evaporator and the surrounding temperature are reduced, the refrigeration chamber of the evaporator is refrigerated, and the refrigerant is changed into low-temperature and low-pressure gas.

The refrigerant from the evaporator returns to the compressor, the above process is repeated, energy conversion is carried out through the state change of the refrigerant, and the heat in the refrigerator is transferred to the air outside the refrigerator, so that the refrigeration cycle of the refrigerator is realized.

Because the compressor also needs to work when the refrigeration cycle system works, vibration is inevitably generated in the working process of the compressor, the vibration can be transmitted to the layer frame 3 along the transmission path through the cabinet body 1, the quality of the articles placed on the layer frame 3 can be reduced after the articles are vibrated, and particularly, the quality of red wine is greatly affected by the vibration; therefore, as shown in fig. 5 and 8, the refrigerator is provided with a buffer member 4 between the shelf 3 and the supporting portion 121, so that the shelf 3 is suspended in the storage chamber 122, and the buffer member 4 buffers and absorbs the shock transferred from the cabinet 1 to the shelf 3, thereby reducing the shock received by the shelf 3; the buffer member 4 is disposed in the transmission path to reduce the transmission effect of the vibration, so as to reduce the vibration received by the shelf 3; it should be further noted that, the cushioning members 4 are generally configured to be four, and the four cushioning members 4 are correspondingly disposed at four corners of the layer frame 3, so that the layer frame 3 can be uniformly stressed.

Specifically, as shown in fig. 11 and 12, the cushion member 4 is internally defined with a cushion chamber 44, and the cushion chamber 44 is filled with air; when vibration generated by the operation of the compressor is transmitted to the layer frame 3 through the buffer member 4, the vibration is buffered and absorbed by the buffer cavity 44, so that the vibration suffered by the layer frame 3 can be reduced; it should be noted that, the buffer cavity 44 is a closed cavity, and the buffer member 4 is made of soft rubber or silica gel; it should be noted that, when the cushioning member 4 is subjected to vibration, the cushioning member 4 may be compressed or stretched, and since the cushioning chamber 44 is a closed chamber, the layer frame 3 and the supporting portion 121 are not in rigid contact in general no matter whether the cushioning member 4 is compressed or stretched; in addition, it should be noted that, the buffer cavity 44 is filled with air and is a closed cavity, on one hand, the air can buffer the vibration, and when the buffer member 4 is subjected to the vibration, the air in the buffer cavity 44 can be adaptively adjusted under the vibration action so as to buffer and absorb the vibration; on the other hand, the effect of air on vibration transmission is inferior to that of solid, and therefore, the buffer 4 is provided on the vibration transmission path to reduce the effect of vibration transmission.

As shown in fig. 6, the first connecting plate 33 and the second connecting plate 34 are respectively provided with a connecting hole 31 at both ends in the width direction of the cabinet 1, and the buffer member 4 is provided in the connecting hole 31 so that the shelf 3 is connected with the buffer member 4; the other end of the buffer 4 is abutted against the supporting part 121, so that the buffer 4 is reliably arranged between the layer frame 3 and the supporting part 121; the buffer member 4 has a gap between an end extending into the connecting hole 31 and an inner wall of the connecting hole 31 facing the opening of the connecting hole.

In some embodiments, as shown in fig. 9 and 10, a positioning portion 311 is disposed at an opening of the connection hole 31, the buffer member 4 is provided with a positioning cavity 421, the positioning cavity 421 is disposed at an outer periphery of the buffer member 4 and near one end of the buffer member 4 extending into the connection hole 31, and the positioning portion 311 is disposed in the positioning cavity 421 to position a connection position of the buffer member 4 and the connection hole 31, so as to increase reliability of connection between the buffer member 4 and the layer frame 3.

As shown in fig. 11 and 12, the cushion 4 includes a connecting portion 41, an intermediate portion 42, and a contact portion 43, the connecting portion 41 being connected to the layer frame 3, the contact portion 43 being connected to the supporting portion 121, one end of the intermediate portion 42 being connected to one end of the connecting portion 41 remote from the layer frame 3, the other end of the intermediate portion 42 being connected to the contact portion 43 so as to interconnect the connecting portion 41 and the contact portion 43; it should be noted that, in some embodiments, the buffer cavity 44 is disposed through the middle portion 42 and extends to the connecting portion 41 and the contact portion 43, so that the size of the buffer cavity 44 is as large as possible, thereby increasing the shock absorbing effect of the buffer 4 on the shelf 3.

In some embodiments, since the positioning portion 311 is disposed at the opening of the connecting hole, the inner diameter of the opening of the connecting hole is smaller than the inner diameter of the connecting hole, so that the connecting portion 41 is extended into the connecting hole 31, and the outer diameter of the connecting portion 41 is gradually increased from the end of the connecting portion extending into the connecting hole 31 to the end connected with the middle portion 42; the maximum value of the outer diameter dimension range of the connecting portion 41 is the inner diameter dimension of the connecting hole 31; it should be noted that, an outer diameter of an end of the connecting portion 41 connected to the middle portion 42 is larger than an outer diameter of the middle portion 42, and an outer diameter of an end of the contacting portion 43 connected to the middle portion 42 is larger than an outer diameter of the middle portion 42, so that the connecting portion 41, the middle portion 42 and the contacting portion 43 together define a positioning cavity 421; when the positioning portion 311 is disposed in the positioning cavity 421, the side wall of the positioning portion 311 facing the connecting hole 31 is abutted against the side of the connecting portion 41 facing the positioning cavity 421, and the side wall of the positioning portion 311 facing away from the connecting hole 31 is abutted against the side of the contact portion 43 facing the positioning cavity 421, so as to prevent the positioning portion 311 from moving randomly in the positioning cavity 421, thereby increasing the connection firmness of the buffer 4 and the shelf 3; in addition, the outer diameter of the contact portion 43 is larger, so that the contact area between the contact portion 43 and the supporting portion 121 can be increased, and the stress area of the buffer member 4 can be increased, and the pressure applied to the buffer member 4 can be reduced, in addition to the positioning cavity 421 defined by the contact portion 43 and the connecting portion 41.

The installation method and the working principle of the buffer piece 4 in the refrigerator are as follows: the connecting part 41 is arranged in the connecting hole 31, the positioning part 311 is clamped into the positioning cavity 421 so as to connect the buffer 4 with the shelf 3, and the contact part 43 is abutted against the supporting part 121 so as to mount the shelf 3 in the storage chamber 122; when the refrigeration cycle system supplies cold for the storage chamber 122, the compressor generates vibration, the vibration is transmitted to the layer frame 3 through the cabinet body 1 along the transmission path through the buffer piece 4, when the vibration passes through the buffer piece 4, the vibration is transmitted by air in the buffer cavity 44, on one hand, the air in the buffer cavity 44 absorbs the vibration, on the other hand, the air in the buffer cavity 44 has weak transmission effect on the non-absorbed vibration, and the vibration transmitted to the layer frame 3 is reduced, so that the layer frame 3 is kept stable; it should be noted that, since the buffer member 4 is made of soft rubber or silica gel, the soft rubber or silica gel itself can also absorb shock.

The refrigerator is provided with the buffer piece 4, so that vibration generated during operation of the refrigerator is transmitted to the layer frame 3 through the buffer piece 4, and the buffer cavity 44 is arranged in the buffer piece 4 to buffer and absorb the vibration, so that the vibration suffered by the layer frame 3 is reduced, the layer frame 3 is kept stable, and the influence of the vibration on the quality of an object placed on the layer frame 3 is reduced; the buffer cavity 44 is filled with air, and vibration is absorbed by utilizing the air for buffering, so that the effect is good, the structure is simple, and the assembly and the disassembly are convenient; and the refrigerator has good storage effect on wine bodies.
