Double-temperature air cooling refrigerator

Abstract

The invention relates to the technical field of refrigerators, and in particular relates to a double-temperature air cooling refrigerator. The double-temperature air cooling refrigerator comprises a cabinet body and a refrigeration system, wherein a door body is arranged at an opening of the cabinet body, a baffle is arranged in the cabinet body, the baffle divides the inner part of the cabinet body into a freezing chamber and a refrigerating chamber, and the freezing chamber and the refrigerating chamber are communicated by an air guide opening; the refrigeration system comprises a compressor, a condenser, a throttling device and an evaporator, which are sequentially connected in series, an accommodation cavity is arranged in the baffle, the evaporator is arranged in the accommodation cavity, a draught fan is arranged in the accommodation cavity, and an air outlet communicated with the freezing chamber is formed in one side of the accommodation cavity close to the freezing chamber. According to the double-temperature air cooling refrigerator provided by the invention, the evaporator and the draught fan for only blowing cold air to the freezing chamber and arranged between the freezing chamber and the refrigerating chamber accelerate the cooling speed of the freezing chamber, cold air is injected into the refrigerating chamber through the air guide opening so as to cool the refrigerating chamber, both of the freezing chamber and the refrigerating chamber adopt air cooling, so frost is not generated on the inner wall of the cabinet body easily, and moreover as the air flow speed is high, the temperatures in the freezing chamber and the refrigerating chamber are quite uniform.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to a dual-temperature air-cooled refrigerator. Background technique [0002] With the development of today's society, people's requirements for refrigeration products are getting higher and higher. Existing freezers are mainly single-temperature freezers, and coiled tube evaporators are usually installed around the freezer. The coiled tube evaporators are arranged on the side walls. When the evaporator absorbs heat, the air near the evaporator cools down quickly. Natural convection is formed in the freezer to reduce the temperature in the freezer. The coiled tube evaporator is used to directly cool the inside of the freezer, the cooling speed is slow, and the inside of the freezer is prone to frost and the temperature is uneven. A small number of dual-temperature freezers also use part of the pipeline of the coiled evaporator to bypass the outer wall of the refrigerator. The...
