Embodiment Construction

[0018] In this example, if figure 1 As shown, an air duct heating control system for an air-cooled refrigerator includes a defrosting heater 5, an ambient temperature sensor, a refrigeration sensor 2, a temperature fuse, a fan 6, a potentiometer and a control board, and controls the entire refrigerator together with the refrigeration system . The defrosting heater 5 is arranged on the surface of the evaporator accumulator; the refrigeration sensor 2 is arranged at the lower right part of the refrigeration air duct of the refrigerator; the fan 6 is arranged at the middle and upper part of the refrigerator; at the air inlet of the refrigerator refrigerator, and A compensation heater is provided at a position 4 close to the freezer; the compensation heater is used to realize the control structure of the air duct from the freezer to the refrigerator.

[0019] Refrigeration and freezing require refrigeration is controlled by the control board based on the data collected by the tem...

Abstract

The invention discloses an air-cooling refrigerator air flue heating system and a control method thereof. The air-cooling refrigerator air flue heating system is characterized in that the system is installed on an air inlet of a refrigerating chamber of a refrigerator, and the position, close to a freezing chamber, of the refrigerator is provided with a compensation heater; and the compensation heater is used for obtaining a control structure of an air-cooling refrigerator air flue. The air-cooling refrigerator air flue heating system can avoid the risk that the refrigerator may not carry out refrigeration under the condition that the refrigerator is at low circumstance temperature.

Description

technical field [0001] The invention relates to an air duct heating system of a two-door air-cooled electric-controlled refrigerator and a control method thereof, belonging to the field of automatic control of electric-controlled air-cooled refrigerators. Background technique [0002] At present, two-door air-cooled electric-controlled refrigerators operate at low ambient temperatures. Due to the air blowing from the freezer to the refrigerator, the design of the air outlet structure is unreasonable. In the running cycle, there is a situation that the freezer is blocked and blown to the air duct of the refrigerator, resulting in the risk of no refrigeration in the refrigerator. Contents of the invention [0003] The present invention aims to improve the deficiencies in the existing structural design, and provides an air-cooled refrigerator air duct heating system and its control method, in order to solve the problem that the refrigerator room may The risk of non-refrigera...
