Anti-condensation method and device for glass door and refrigerator

Abstract

The invention provides an anti-condensation method for a glass door. The anti-condensation method includes the following steps of: determining an average temperature of the outer surface of the glass door and an environment dew point temperature based on an environment temperature acquisition value, an environment humidity acquisition value, an in-cabinet temperature acquisition value and a preset parameter value; comparing the average temperature of the outer surface of the glass door with the environment dew point temperature, and determining the required power of an electric heater when the average temperature of the outer surface of the glass door is lower than or equal to the environment dew point temperature; adjusting the electric heater to run for a heating period at the required power; and acquiring the data are again, updating the required power of the electric heater, and controlling the electric heater to run for a next heating period. The invention further provides an anti-condensation device adopting the method and a refrigerator. The anti-condensation device can conduct variable-power operation according to a change of an environment temperature, thereby completely eradicating generation of condensation on a glass door body and also avoiding the problem of high energy consumption caused by excessive heating.

Description

technical field [0001] The invention belongs to the technical field of refrigerators, and in particular relates to a method and device for preventing condensation on a glass door and a refrigerator. Background technique [0002] In order to undertake the task of freezing and refrigerating food, the freezer needs to run all day or even all year round, so its power consumption cannot be underestimated. However, there is condensation on the glass door. The condensation on the glass door not only hinders the sight of consumers, but also increases the heat load of the refrigerator. [0003] At present, the most commonly used anti-condensation device for glass doors is an electric heater, but there are contradictions in setting up the electric heater: on the one hand, the electric heater is used to heat the glass, so that the temperature of the outer surface of the glass door is higher than the dew point temperature of the air , to prevent condensation and reduce the thermal load...
