Refrigerator provided with air channel assembly and control method thereof

Abstract

The invention discloses a refrigerator provided with an air channel assembly and a control method thereof, and relates to the technical field of refrigerators. The refrigerator provided with the air channel assembly comprises a refrigerator body in which the air channel assembly is arranged, wherein the air channel assembly comprises a fan assembly, a front cover plate of an air channel, and a rear cover of the air channel; the rear cover of the air channel covers the front cover plate of the air channel; an air channel chamber is formed between the front cover plate of the air channel and therear cover of the air channel; a plurality of freezing air outlets are formed in one surface of the front cover plate of the air channel; at least one interlayer chamber body which is filled with a phase-changed coolant is arranged on the front cover plate of the air channel; a controller is arranged in the refrigerator body and is correspondingly connected to a variable-frequency compressor, thefan assembly and a room temperature sensor. According to the refrigerator provided with the air channel assembly and the control method thereof, an empty chamber which is filled with the coolant is designed in the front cover plate of the air channel; the controller is arranged in the refrigerator body and is used for controlling the rotating speed of the fan assembly and the variable-frequency compressor; and the coolant is used for storing cold, and thus the problem that the temperature of a freezing chamber of an air-cooled refrigerator increases again while a defrosting heater performs heating, resulting in the spoilage of foods in the freezing chamber, can be avoided.

Description

technical field [0001] The invention belongs to the technical field of refrigerators, in particular to a refrigerator with an air duct assembly and a control method thereof. Background technique [0002] Air-cooled refrigerators use fans to force convection to exchange heat between the hot air in the compartment and the evaporator, thereby achieving the purpose of cooling the box. After a long period of cooling, the air-cooled refrigerator needs to be defrosted. Generally, it is judged according to the running time and sensor temperature. The defrosting heater is used to heat the evaporator, and the defrosting is stopped after reaching a certain temperature. [0003] However, when the existing air-cooled refrigerator is heated by the defrosting heater, the temperature of the freezer is also easy to rise, and in some cases the temperature in some positions may even rise above zero, which is unfavorable for food storage in the freezer.

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide an air duct assembly of a refrigerator and the refrigerator thereof. A cavity is designed in the front cover of the air duct, and the interior is filled with a cool storage agent. A controller is arranged in the box, and the fan assembly and frequency conversion compression are controlled by the controller. The rotation speed of the machine makes the cold storage agent store cold, which solves the problem that the temperature of the freezing chamber rises when the defrosting heater heats up the existing air-cooled refrigerator, which leads to the deterioration of the food in the freezing chamber
