Fig. 1 and Fig. 2 is referred to, this utility model provides a kind of wind cooling refrigerator, and the wind cooling refrigerator includes casing 100, with And the refrigeration and defrosting system in the casing 100, the refrigeration and defrosting system include:
Refrigeration cycle, compressor 10 that the refrigeration cycle includes being sequentially connected in series by refrigeration pipe, freeze it is cold Condenser 20, refrigeration restricting element 30 and refrigerating evaporator 40;And,
Defrost pipeline, the gas outlet and gas returning port for connecting the compressor 10 are arranged, and are sequentially provided with the defrost pipeline Defrost condenser 50, defrost restricting element 60 and defrosting evaporator 70, the defrost condenser 50 and the refrigerating evaporator 40 are finned heat exchanger, and the defrost condenser 50 is in be arranged side by side with the refrigerating evaporator 40;And,
Multiple switching devices, located at the defrost pipeline and the refrigeration cycle junction, to control describedization White pipeline is connected with the refrigeration cycle.
In the present embodiment, the casing 100 is provided with refrigerating chamber 110 and cold room 120, as shown in figure 3, the casing 100 are provided with refrigerating chamber 110 and cold room 120, as shown in Figure 3 and Figure 5, are provided with blower fan 130 in the side wall of the casing 100 And air channel 140, the air channel 140 includes refrigerating chamber air delivery duct(It is not shown)With refrigerating chamber air -return duct(It is not shown), and cold preservation Room air delivery duct 141 and cold room air -return duct 142, when the blower fan 130 works, drive the air-flow of 130 circumference of blower fan in institute Flowing in air channel 140 is stated, heat exchange is carried out with the refrigerating chamber 110 and cold room 120 for the refrigeration cycle.
As shown in Figure 2(Wherein, solid arrow is kind of refrigeration cycle direction, and dotted arrow is defrost loop direction), the wind The refrigerative circle system of cold refrigerator is:After having cold-producing medium, cold-producing medium to be compressed in the compressor 10 in refrigeration pipe, from which Gas outlet escapes and enter the refrigerant condenser 20, after being exchanged heat in the refrigerant condenser 20, refrigeration section described in Jing 30 reducing pressure by regulating flow of fluid element, subsequently into released cold quantity in the refrigerating evaporator 40, finally from the return-air of the compressor 10 Mouth is returned in the compressor 10, so as to complete a kind of refrigeration cycle, and carries out next round circulation.Wherein, cold-producing medium is described When carrying out heat exchange in refrigerating evaporator 40, air channel 140 described in the cold Jing of generation flows to the refrigerating chamber 110 of the casing 100 Or cold room 120, for storing food.
As the refrigerating evaporator 40 is to carry out heat exchange, the fin of the refrigerating evaporator 40 using convection type Surface frosting is very fast, can affect the refrigerating efficiency of the refrigerating evaporator 40, therefore needs to change the refrigerating evaporator 40 Frost.In the present embodiment, the defrost pipeline to the process that the refrigerating evaporator 40 carries out defrost is:In the refrigeration evaporator When device 40 occurs frosting, after cold-producing medium is compressed in the compressor 10, discharge from its gas outlet, through the switching device When, part of refrigerant enters the refrigerant condenser 20, starts above-mentioned refrigerative circle system;And another part cold-producing medium is entered The defrost condenser 50, the release heat in the defrost condenser 50,60 reducing pressure by regulating flow of defrost restricting element described in Jing, so Heat exchange is carried out in the defrosting evaporator 70 afterwards, is finally converged with front portion cold-producing medium, and from the compressor 10 Gas returning port return in the compressor 10.Wherein, release heat when cold-producing medium carries out heat exchange in the defrost condenser 50 Amount, due to the defrost condenser 50 with the refrigerating evaporator 40 in being arranged side by side, so as to using the defrost condenser 50 The heat for the being discharged air-flow circumferential to the fin of the refrigerating evaporator 40 heats up, so that the refrigerating evaporator Frost thawing on 40 fin, realizes the defrost process to the refrigerating evaporator 40 with this.
With being carried out continuously for above-mentioned process of refrigerastion and defrost process, in 40 continuous released cold quantity of the refrigerating evaporator, To be supplied to the refrigerating chamber 110 or cold room 120 to preserve food, and the defrost condenser 50 constantly discharges heat, to institute The air-flow for stating the fin circumference of refrigerating evaporator 40 is heated up, to melt the frost of the fin of the refrigerating evaporator 40, so as to Realization can also carry out defrost to the refrigerating evaporator 40 while the wind cooling refrigerator persistently carries out process of refrigerastion.
Technical solutions of the utility model, by connecting the defrost pipe in the gas outlet of the compressor 10 and gas returning port Road, and be in be arranged side by side by the defrost condenser 50 and the refrigerating evaporator 40, directly condensed using the defrost with this The heat discharged by device 50 air-flow circumferential to the fin of the refrigerating evaporator 40 heats up so that the refrigerating evaporator Frost thawing on 40 fin, so as to realize can also be to the refrigeration while wind cooling refrigerator persistently carries out process of refrigerastion Vaporizer 40 carries out defrost.
Fig. 4 and Fig. 5 is referred to, in the present embodiment, the defrost condenser 50 and the refrigerating evaporator 40 are located at In the side wall of the refrigerating chamber 110, the defrosting evaporator 70 is arranged in the side wall of the cold room 120.
Specifically, the defrost condenser 50 and the refrigerating evaporator 40 are located at the rear wall of the refrigerating chamber 110, The defrosting evaporator 70 is arranged at the upper side wall of the cold room 120.
When the wind cooling refrigerator carries out process of refrigerastion and defrost process simultaneously:The defrost condenser 50 discharges heat pair The refrigerating evaporator 40 carries out defrost;Refrigerating chamber air delivery duct described in a part of Jing of cold of the release of the refrigerating evaporator 40 supplies To the refrigerating chamber 110, cold room air delivery duct 141 described in another part cold Jing is flowed in the cold room 120;It is described 70 released cold quantity of defrosting evaporator, and the cold room 120 is supplied to, make the cold room 120 lower the temperature.Arranged with this, fully Make use of during defrost is carried out, the cold of the release of the defrosting evaporator 70 is lowered the temperature to the cold room 120, it is to avoid The waste of defrost energy, reduces the energy consumption of the wind cooling refrigerator.
Further, the heat for producing the cold room 120 using the cold room air -return duct 142, is supplied to institute Stating refrigerating evaporator 40 carries out defrost, to strengthen the defrost effect to the refrigerating evaporator 40, and in order to maximally utilize The heat of the generation of cold room 120 is stated, in defrost, the cold room air delivery duct 141 is closed so that the refrigerating evaporator 40 is released The cold put can not enter the cold room 120, cold room air -return duct described in the heat Jing produced so as to the cold room 120 142 are sent on the refrigerating evaporator 40, carry out defrost to the refrigerating evaporator 40.
The defrost condenser 50 is various in the mode being arranged side by side with the refrigerating evaporator 40, such as described defrost is cold Condenser 50 is arranged side by side in ectonexine with the heat exchanger tube of the refrigerating evaporator 40, and the defrost condenser 50 and the refrigeration The fin of vaporizer 40 can be in side by side or being stacked, also or the defrost condenser 50 is passed through with the refrigerating evaporator 40 Same fins set connection.
