Detailed Description

The following description of the embodiments of the present utility model 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 utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The present application is described in further detail below in conjunction with fig. 1.

A quick freezing cabinet comprises a cabinet body 1, a refrigerating unit 2 and a defroster 3.

The refrigeration unit 2 includes a compressor 4, an evaporator 5, and a condenser 6, and the defroster 3 includes a liquid storage tank 7, a connection pipe 8, and a heating coil 9. The liquid storage tank 7 is added with sodium chloride aqueous solution. The refrigeration unit 2 contains a refrigerant. The evaporator 5, the condenser 6, the liquid storage tank 7 and the connecting pipe 8 are all made of copper alloy. The compressor 4, the condenser 6 and the liquid storage tank 7 are placed outside the cabinet 1.

The condenser 6 is arranged on the liquid storage tank 7, and a radiating fin 10 is arranged on one side of the condenser 6 away from the liquid storage tank 7; the heat radiation fin 10 is provided with an exhaust fan 11, the liquid storage tank 7 is provided with a temperature sensor 12, and the temperature sensor 12 is electrically connected to the exhaust fan 11. The heat emitted by the condenser 6 when condensing and liquefying the refrigerant is absorbed by the liquid in the liquid storage tank 7 for subsequent use; the heat radiation fins 10 and the exhaust fan 11 ensure that the temperature of the condenser 6 and the liquid storage tank 7 is not too high to influence the condensation of the condenser 6.

The connecting pipe 8 is abutted on the evaporator 5, the heating coil 9 is placed in the connecting pipe 8, the connecting pipe 8 is connected on the liquid storage tank 7 in a head-tail mode, a water pump 13 is arranged at the bottom of the liquid storage tank 7, a water outlet of the water pump 13 is connected at one end of the connecting pipe 8, a pressure sensor 14 is arranged on the water pump 13, and the pressure sensor 14 is electrically connected on the heating coil 9. During defrosting, the water pump 13 is driven to work, liquid in the liquid storage tank 7 circulates in the connecting pipe 8, the liquid in the connecting pipe 8 releases heat, ice cubes condensed on the evaporator 5 are defrosted, and the aim of defrosting is achieved; when the connecting pipe 8 is blocked, the pressure of the water pump 13 rises, the heating coil 9 in the connecting pipe 8 works to defrost the ice cubes blocked in the connecting pipe 8, so that the defrosting efficiency is ensured.

The implementation principle of the embodiment is as follows: during refrigeration, the liquid in the liquid storage tank 7 is heated up by the liquid storage tank 7 through absorbing heat emitted by the condenser 6; during defrosting, the water pump 13 is driven to work so as to circulate the heated liquid through the connecting pipe 8, and the heat of the heated liquid is used for defrosting the ice cubes condensed on the evaporator 5 through the connecting pipe 8, so that the aim of defrosting is fulfilled; when the temperature of the liquid storage tank 7 is too high, the air exhaust fan 11 is driven to work, so that the temperatures of the liquid storage tank 7 and the condenser 6 are reduced, and the refrigeration effect is prevented from being reduced due to the too high temperature of the condenser 6; when connecting pipe 8 takes place to block up during the defrosting, heating coil 9 unfreezes the ice-cube that blocks up in connecting pipe 8, has guaranteed the efficiency of defrosting.

The heat emitted by the condenser 6 is absorbed through the liquid storage tank 7, and the water pump 13 is driven to work so as to circulate the heated liquid in the connecting pipe 8, thereby achieving the defrosting effect and having the advantage of higher defrosting speed; meanwhile, the temperature of the condenser 6 is controlled not to be too high to influence refrigeration by the arrangement of the temperature sensor 12 and the pressure sensor 14, and the defrosting effect is prevented from being influenced by the blocking of the connecting pipe 8, so that the function of the defroster 3 can be better exerted.
