Refrigeration system can be made of compressor set 100, condenser 202, restricting element 300 and evaporative component 600 etc.
Cooling cycle system.Evaporative component 600 is configured to directly or indirectly provide cold into storing compartment 410.For example, when this is cold
When hiding refrigerating plant as household compression direct cooling refrigerator, evaporative component 600 may be disposed on the outside of the rear surface of inner container of icebox or interior
Side.When the refrigerating device is household compression wind cooling refrigerator, also there is evaporator room in babinet 400, evaporator room leads to
It crosses air path system to connect with storing compartment 410, and evaporative component 600 is set in evaporator room, exit is provided with wind turbine, with
Circularly cooling is carried out to storing compartment 410.Since such babinet 400, door body 500, refrigeration system are people in the art in itself
Member is known and is easily achieved, in order not to cover and obscure the inventive point of the present embodiment, hereinafter to babinet 400, door body 500, system
Cooling system does not repeat in itself.
Referring to Fig. 1, a kind of refrigerator is present embodiments provided, including：Babinet 400, door body 500 and refrigeration system.Babinet
Storing compartment 410 is defined in 400.Door body 500 is connected to 400 forepart of babinet, to be opened and closed storing compartment 410.Fig. 2 is the present invention
One pipeline connection diagram of the condensation of refrigerator, referring to Fig. 2, refrigeration system is used to provide cold to storing compartment 410,
And refrigeration system is included by the sequentially connected compressor set 100 of refrigerant line, condensation, restricting element 300, Yi Jizheng
Send out component 600.And evaporative component 600 is connected with compressor 100 by refrigerant line.Wherein, condensation includes：It is anti-condensation
Reveal pipe 201 and condenser 202.Anti-condensation pipe 201 is set at least part region that babinet 400 is contacted with door body 500, profit
Prevent region from condensation occur with the heat of itself.Condenser 202 fits in the shell of babinet 400, to utilize shell to ice
Heat is distributed outside case.Refrigeration system further includes bypass pipe 203 and refrigerant flow direction switching device, one end of bypass pipe 203 with it is cold
Condenser 202 connects, and the other end is connect after passing through 600 inside of evaporative component with restricting element 300.Refrigerant flow direction switching device
It is connect respectively with bypass pipe 203 and anti-condensation pipe 201, and is configured to that refrigerant selection is made to flow through bypass pipe 203 or anti-condensation
Pipe 201.
It was found by the inventors of the present invention that refrigerator is in use that will press there are a main cause of loss of refrigeration capacity
When the refrigerant that contracting unit 100 is discharged is directly accessed evaporative component 600 and is defrosted, the refrigerant temperature is excessively high, in defrosting
A large amount of losses of cold in refrigerator are caused simultaneously.So as to which the energy consumption of refrigerator be caused to increase.Also, if refrigerant temperature is too low,
Although the loss of refrigerator cold can be reduced, its defrosting effect is unsatisfactory, seriously affects user and uses body to refrigerator
It tests.
And in the present embodiment, it is connect using one end and condenser 202 of bypass pipe 203, the other end passes through evaporative component
Inside 600.Refrigerant its moderate temperature flowed out by condenser 202, can either fully defrost, and can prevent temperature is excessively high to make
Into refrigerator loss of refrigeration capacity.Therefore, while ensureing to defrost, the effect for reducing refrigerator loss of refrigeration capacity is had also achieved, so as to reduce
Refrigerator energy loss.
In addition, existing refrigerator is mostly the main power source for using compressor set 100 as defrosting, refrigerator should be used for
Refrigeration defrosts again for heat production, therefore the pressure imbalance of refrigerator refrigeration system is caused in the mutual handoff procedure of function, makes
Obtain refrigeration system fluctuation of service.And since one end of bypass pipe 203 is connect with condenser 202 in the present embodiment, the other end
It is connect after across 600 inside of evaporative component with restricting element 300.So as to make entire refrigeration system pressure using restricting element 300
Balance.
Referring to Fig. 2, further, refrigerant flow direction switching device includes triple valve 204, first end to third end point
Entrance not with the outlet of condenser 202, one end of bypass pipe 203 and anti-condensation pipe 201 is connect, so that refrigerant selection flows through
Bypass pipe 203 or anti-condensation pipe 201.
When the first end of triple valve 204 is connected with second end, refrigerant flows through bypass pipe 203 by the outlet of condenser 202
Into evaporative component 600, subsequently into restricting element 300；When the first end of triple valve 204 is connected with third end, refrigerant
Anti-condensation pipe 201 is flowed through by the outlet of condenser 202 and enters restricting element 300.
Referring to Fig. 2, further, refrigerant flow direction switching device is configured to：In the case where refrigerator is defrosted, make three
The first end of port valve 204 is connected with second end；In the case of the non-defrosting of refrigerator, make the first end of triple valve 204 and third end
Conducting.
It is it should be noted that refrigerator defrosts it may is that button by being arranged on refrigerator, is touched by user
It touches so that refrigerator defrosts.Alternatively, refrigerator carries out defrosting forms gearing cooperation, such as refrigerator door with other component in refrigerator
500 opening and closing is corresponding with the startup of dew removing and stopping.
Referring to Fig. 2, further, refrigerant flow direction switching device is configured to：In the situation that compressor set 100 is out of service
Under, the first end of triple valve 204 is made to be connected with second end；In the case where compressor set 100 is run, make the of triple valve 204
One end is connected with third end.
Since compressor set 100 is when shutting down, if the refrigerant in condenser 202 is vacant, will cause to waste, and at this time
Frost is formed in refrigerator and easily, so in the case where compressor set 100 is out of service, makes the first end of triple valve 204 and the
Three ends are connected；The refrigerant in condenser 202 can be made full use of, prevents from causing to waste, while also eliminates in refrigerator and is formed
Frost.
Further, triple valve 204 is solenoid valve.
Referring to Fig. 2, further, the entrance front end of restricting element 300 is equipped with device for drying and filtering 700, device for drying and filtering
700 entrance is connect simultaneously with the outlet of the other end and anti-condensation pipe 201 of bypass pipe 203.Evaporative component 600 and compressor set
The pipeline of 100 connections is passed through in restricting element 300；Evaporative component 600 and the pipeline that compressor set 100 is connect are from restricting element
It is passed through in 300, evaporative component 600 is equipped with liquid storage packet 800 with the pipeline that compressor set 100 is connect, so that evaporative component 600
The refrigerant of outflow is followed by liquid storage packet 800, in restricting element 300 and compressor set 100.
So far, although those skilled in the art will appreciate that detailed herein have shown and described multiple showing for the present invention
