Refrigerator with anti-condensation device and anti-condensation control method

Abstract

The invention discloses a refrigerator with an anti-condensation device and an anti-condensation control method, and relates to the technical field of refrigerators. The refrigerator comprises the anti-condensation device, wherein the anti-condensation device comprises a temperature sensor, a temperature and humidity sensor and a heating device; the temperature sensor is used for detecting the temperature on the surface of an overturning beam; the temperature and humidity sensor is used for detecting the ambient temperature and humidity; the heating device is used for heating; the temperaturesensor, the temperature and humidity sensor and the heating device are electrically connected to a control module; the control module converts the collected ambient temperature and humidity data intothe ambient dew point temperature; and when the temperature, collected by the temperature sensor, at the surface position of the overturning beam reaches a target temperature, the control module controls the heating device to start heating. By means of the anti-condensation device and the anti-condensation control method, the anti-condensation heating device can be controlled to be turned on and off more intelligently, the problem that the overturning beam of the refrigerator is prone to condensing is greatly relieved, and the energy consumption of the refrigerator is reduced.

Description

technical field [0001] The invention belongs to the technical field of refrigerators, in particular to a refrigerator with an anti-condensation device and an anti-condensation control method. Background technique [0002] Condensation is a phenomenon in which a high-temperature, high-humidity gas liquefies into a liquid on its surface when it reaches the dew point temperature when it encounters a low-temperature object. Since the temperature inside the refrigerator is much lower than the temperature outside the box, the cooling capacity in the box will leak to the outside, especially in the parts that are in contact with the box and the door, the gas is easy to condense and condense into dew, resulting in condensation. [0003] In the prior art, the problem of condensation in refrigerators is solved by arranging heating devices at places prone to condensation, collecting ambient temperature and humidity through humidity sensors, determining the dew point temperature of the a...

AI Technical Summary

Problems solved by technology

This method can effectively judge the dew point temperature, but the start-stop ratio requires a lot of test data; at the same time, the start-stop ratio of the heating device is fixed, and it cannot be effectively controlled adaptively according to the surface temperature of the rotating beam
