Air-cooled refrigerator

Abstract

The invention discloses an air-cooled refrigerator, and relates to the technical field of refrigeration equipment. An air channel front plate and an air channel rear plate are connected in a matched manner. A freezing chamber air channel and a refrigerating chamber air channel communicating with the top of the freezing chamber air channel are formed on the left side of the inner portion. A cavity is formed in the right side of the inner portion. Heat preservation foam is connected in the cavity in a matched manner, and an air channel structure is formed by the heat preservation foam, the air channel front plate and the air channel rear plate. A variable-temperature chamber air channel independent from the refrigerating chamber air channel and the freezing chamber air channel is arranged on the heat preservation foam. An independent fan is arranged in the variable-temperature chamber air channel, and a fan is arranged in the freezing chamber air channel. According to the air-cooled refrigerator, on the basis of a single evaporator, the refrigerating chamber air channel, the freezing chamber air channel and the variable-temperature chamber air channel are arranged, wherein the refrigerating chamber air channel communicates with the freezing chamber air channel, and the variable-temperature chamber air channel is independent from the refrigerating chamber air channel and the freezing chamber air channel, and therefore independent temperature control of a variable-temperature chamber of the refrigerator is achieved, and the temperature control efficiency is high; a heater is further arranged at the bottom of the variable-temperature chamber, free switching of the variable-temperature chamber at a refrigerating temperature interval and a freezing temperature interval is achieved, adaptability is good, and flexibility is high; and the structure is simple, the occupied size is small, and refrigeration efficiency is high.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a refrigerator. Background technique [0002] A refrigerator is a refrigeration device that maintains a constant low temperature. It is a common electrical appliance used for low-temperature preservation of food or other items in daily life. It is widely used in life and industry. With the development of technology in the refrigerator industry and the improvement of residents' living standards, large-volume air-cooled refrigerators have gradually become products favored by consumers. At present, the air-cooled refrigerator with single evaporator adopts a single fan structure, the air supply duct system is installed in the room where the evaporator is located, the damper is installed on the air supply duct, and the temperature sensors are arranged in each compartment, and the temperature of different compartments is realized through the damper. control. However, ...
