Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 provides the working principle diagram in the utility model embodiment.
In figure, compressor 1, evaporator 2, condenser 3, first pipe 4, second pipe 501, solenoid valve 502, control circuit
Plate 503, tee tube 504, air filter 6, throttling element 7, liquid storage cylinder 8.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing and by embodiment, and following embodiment is pair
The explanation of the utility model and the utility model is not limited to following embodiment.
As shown in Figure 1, this has the refrigeration system of refrigerator of defrosting function, including compressor 1, condenser 3 and evaporator 2,
The outlet end of the input end of compressor 1 and evaporator 2, the input end of the outlet end of compressor 1 and condenser 3, condenser 3 go out
It is connected between mouth end and the input end of evaporator 2 by first pipe 4, it is characterised in that: the outlet end of compressor 1 and evaporator
The defroster subsystem for removing the frost accumulated in refrigerator cabinet body is equipped between 2, defroster subsystem includes being connected to going out for compressor 1
The second pipe 501 at mouth end and evaporator 2, second pipe 501 are equipped with solenoid valve 502, solenoid valve 502 and control circuit board
503 connections, a part of high temperature and high pressure gas that compressor 1 is discharged is flowed into evaporator 2 by second pipe 501, thus fastly
Speed improves the temperature of refrigerator cabinet body, so that the intracorporal frost layer of cabinet is quickly melted, eliminates in this way in order to defrost and need first to break
Electricity, then the method melted naturally solve the problems, such as defrosting, realize the function that can be defrosted under energization refrigerating state, eliminate
It needs the intracorporal refrigeration object of refrigerator cabinet to move out to be put into other refrigerator in refrigerating state, wait defrost when original defrosting
The trouble that Cheng Houzai is reentered into.
Specifically, solenoid valve 502 here is solenoid directional control valve, facilitates quickly circulation or stops high temperature and high pressure gas
Flowing, improves control speed；Here second pipe 501 by tee tube 504 with and the outlet end of compressor 1 be connected to
First pipe 4 connect, the setting of tee tube 504 facilitates the connection of second pipe 501, also reduces to 1 needs of compressor
