Example Embodiment

[0024] Example: As shown in Figure 1, the refrigerator anti-condensation heating control device of the present invention includes a heater arranged at the anti-condensation position, and also includes an ambient temperature sensor, a temperature sensor in the box and a control unit. The control unit is based on the environment. The output parameters of the temperature sensor and the temperature sensor in the box are used to control the heater to work.

[0025] The heater power is selected as a constant value according to the size of the anti-condensation part and the heat preservation effect. During production, the heater is pasted on the inner surface of the anti-condensation part, and the ambient temperature sensor is set on the outer surface of the refrigerator, such as the inside of the hinge cover and the top cover. Indoor, door display window, etc., real-time acquisition of current ambient temperature parameters. The temperature sensor in the box is set on the side of th...

Abstract

The invention discloses a refrigerator condensation preventing heating control device and a control method. The heating control device comprises an environmental temperature sensor, a box inner temperature sensor, a control unit and a heater arranged on a condensation preventing position, wherein the control unit utilizes the environmental temperature collected by the environmental temperature sensor as one parameter to control the working state of the heater, and further utilizes the box inner temperature collected by the box inner temperature sensor as an auxiliary parameter to control the the working state of the heater. The refrigerator condensation preventing heating control device disclosed by the invention adopts the environmental temperature sensor and the box inner temperature sensor to control the condensation preventing heater according to the variation of two parameters of the environmental temperature and the box inner temperature, extra cost increase is not needed, and the control program is simplified and meanwhile, the reliability and stability of the system are guaranteed.

Description

Technical field: [0001] The invention relates to a refrigerator anti-condensation heating control device and a control method. Background technique: [0002] French side-by-side refrigerators currently on the market are generally designed with vertical beams between the two refrigerating chamber doors, and multi-door refrigerators are designed with a beam structure between the two freezing chambers. Due to the limitations of the structure and materials, the local insulation performance is poor, and the surface temperature of this part is low when the refrigerator is normally cooled, and condensation is likely to occur. In order to prevent condensation, an electric heater is usually pasted on its inner surface, and the surface temperature is raised by electric heating. [0003] As for the heating control rules of the heater, each manufacturer is slightly different. Generally, there are two heating methods as follows: 1. Use a constant heating ratio; 2. Turn on the heater syn...
