Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the embodiments and accompanying drawings.

[0021] Such as figure 1 , figure 2 As shown, the present invention discloses a defrosting control system for an air-cooled refrigerator, including a defrosting heater 1, a finned evaporator 2, a water receiving tray 4 and a water receiving tray heater 3, and the defrosting heater 1 is embedded in the On the fin evaporator 2, a temperature sensor is arranged on the fin evaporator. The water receiving tray heater 3 is pasted on the surface of the water receiving tray 4 with aluminum foil.

[0022] The present invention also discloses a control method for the defrosting control system of the above-mentioned air-cooled refrigerator, which includes the following steps: when the refrigerator meets the defrosting requirements, turn on the defrosting heater 1, and then turn on the water tray heater 3 after a delay of n1 minutes, When the temperature sens...

Abstract

The invention relates to a defrosting control system for an air-cooled refrigerator and a control method for the same. The defrosting control system comprises a defrosting heater (1), finned evaporators (2), a defrosting tray and a defrosting tray heater (3), wherein the defrosting heater (1) is embedded in the finned evaporators (2); the defrosting tray heater (3) is fixed on the surface of the defrosting tray; and temperature sensors are arranged on the finned evaporators (2). When a defrosting requirement of the refrigerator is met, the defrosting heater (1) is turned on, and the defrosting tray heater (3) is turned on after time delay n1; and when the temperature sensor on the finned evaporator (2) reaches a set temperature value, the defrosting heater (1) is turned off, and the defrosting tray heater (3) is turned off after time delay n2. The defrosting tray is defrosted through delayed turn-on/off of the defrosting tray heater (3), so that the defrosting efficiency is improved, the energy consumption is reduced, and the problem of an ice barrier of a drainage pipe is radically solved.

Description

technical field [0001] The invention belongs to the technical field of refrigerator equipment, and in particular relates to an air-cooled refrigerator defrosting control system and a control method. Background technique [0002] Air-cooled refrigerators are commonly known as frost-free refrigerators. The frost formed on the evaporator is automatically defrosted by the defrost heater, and manual defrosting is not required. [0003] The defrosting system in an air-cooled refrigerator generally includes: evaporator, defrosting heater, defrosting controller, high temperature fuse, water tray, water tray heater, drain pipe and other components. [0004] Frosting process: Start the compressor, the evaporator is refrigerated, absorbs the water vapor in the box, and forms a thin layer of frost on the surface of the evaporator. After a period of on-off cooling, the frost layer of the evaporator thickens and fills the entire evaporator. At this time, the frost on the evaporator needs...
