Low-temperature cryogenic refrigerator with unfreezing function

Abstract

The invention relates to a low-temperature cryogenic refrigerator with an unfreezing function. A heating box is arranged at the upper end of a refrigerator body. An equipment box is arranged at the lower end of the refrigerator body. A partition plate is arranged between the refrigerator body and the heating box. A partition plate is arranged between the refrigerator body and the equipment box. A heater is fixedly mounted on the rear side wall in the heating box. Storage plates are horizontally mounted in the refrigerator body at intervals. A compressor, a transmission motor and an evaporation box are fixedly mounted on the lower bottom surface in the equipment box in sequence from left to right. A transmission shaft is horizontally mounted at the front end of the transmission motor. An exhaust fan is fixedly mounted at the front end of the transmission shaft. Evaporation pipes are uniformly mounted in the evaporation box at intervals. A protective cover is fixedly mounted on the front side wall of the equipment box. The low-temperature cryogenic refrigerator with the unfreezing function is good in heat insulation effect of the refrigerator body, high in sealing performance and rapid and convenient to heat and unfreeze.

Description

technical field [0001] The invention belongs to the technical field related to refrigeration equipment, and in particular relates to a low-temperature cryogenic freezer with a defrosting function. Background technique [0002] With the development of science and technology and the improvement of people's living standards, refrigerators have gradually entered thousands of households. There are also various types of refrigerators, such as horizontal, vertical, freezing, and refrigeration. Types of freezers, they all bring great convenience to people. The freezers in the existing industry only have the single function of refrigeration. If you want to thaw the frozen items, you need to use other heating equipment to heat and thaw them. Additional purchased heating equipment will also take up a certain amount of storage space; refrigerators in the industry usually have poor thermal insulation effects, which will cause the refrigerator to operate for a long time to cool down, whi...

Problems solved by technology

The freezers in the existing industry only have the single function of refrigeration. If you want to thaw the frozen items, you need to use other heating equipment to heat and thaw them. Additional purchased heating equipment will also take up a certain amount of storage space; refrigerators in the industry usually have poor thermal insulation effects, which will cause the refrigerator to operate for a long time to cool down, which will also cause waste of electricity, and a long time operation will also reduce the service life of the freezer
