Abstract

The invention discloses a control system and control method of a refrigerator. A condensation metal plate is arranged in a drawer of the refrigerator, a dehumidifying fan used for enabling air in the drawer to flow to the condensation metal plate is arranged in the drawer, and a groove used for collecting condensation is formed in the drawer; the refrigerator further comprises a drain pipe and a water pan, the drain pipe comprises a U-shaped pipe part and a heating wire, and the two ends of the drain pipe communicate with the groove and the water pan correspondingly; the control system comprises a main control panel and a humidity sensor arranged in the drawer and used for monitoring the humidity in the drawer, and the main control panel is electrically connected with the humidity sensor to obtain the humidity value monitored by the humidity sensor and then conduct treatment; and the main control panel controls opening or closing of an air door and the dehumidifying fan, and the main control panel is electrically connected with the heating wire to control heating or stopping of heating of the heating wire. According to the control system and control method of the refrigerator, the dehumidifying effect of the drawer in a refrigerating chamber is more excellent.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a control system and a control method for a refrigerator. Background technique [0002] Usually, the refrigerator includes a temperature-changing room, and a circulating air duct is arranged inside or outside the temperature-changing room. At least a fan, an evaporator, a heating wire, and a temperature sensor are arranged on the circulating air channel; Return to the return air outlet after the variable room, the humid air in the variable room enters the evaporator, the humid air is condensed or frozen by the evaporator, and becomes dry air, and then sent to the variable room through the air supply port to complete the air circulation transmission, at the same time, Realize the dehumidification control of the variable room. However, in this technology, the dehumidification effect is very poor. Contents of the invention [0003] The purpose of the present inventi...
