Embodiment Construction

[0043] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0044] Such as Figure 1A As shown, in one embodiment, a kind of anti-dew heating control method is provided, comprising:

[0045] Step 102, detecting the ambient humidity.

[0046] In this embodiment, this step detects the ambient humidity of the preset area, specifically, detects the humidity on the surface of the flip beam of the refrigerator. If the surface humidity of the flip beam is high, it is easy to cause condensation on the flip beam. One em...

Abstract

The invention relates to a dewdrop-proof heating control method and device. The method comprises the following steps: detecting environment humidity; obtaining a corresponding first humidity interval according to the environment humidity; controlling a controller to work at a corresponding first operation rate according to the first humidity interval; when the environment humidity changes from the first humidity interval to a second humidity interval, detecting the length of time that the environment humidity is maintained in the second humidity interval; and when the length of time is greater than a preset length of time, controlling a heater to work at a second operation rate corresponding to the second humidity interval. According to the invention, when the humidity changes from one humidity interval to the other humidity interval, the length of time that the humidity is maintained in the latter humidity interval is detected, and whether a heating wire changes the operation ratio to work is controlled according to the length of time; and since the heating wire changes the operation rate only when the length of time is large, the phenomenon that the heating wire changes the operation rate frequently in a short time due to humidity change can be effectively avoided, abnormal working of the heating wire is effectively avoided, and the service life of the heating wire is prolonged.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to a dewdrop prevention heating control method and device. Background technique [0002] Because the inner side of the refrigerator is affected by the cold air in the refrigerator or freezer, the heat on the outer side is absorbed by the inner side, resulting in a lower temperature on the outer side of the refrigerator, and the water vapor around the refrigerator meets some parts with a lower temperature on the outer side of the refrigerator. Water droplets, such as the flip beam on a side-by-side refrigerator, the temperature of the outer surface of the flip beam is relatively low due to internal heat transfer, making it easy to condense water droplets on the outer surface. [0003] In order to avoid dewdrops on the surface of the flip beam, the traditional refrigerator uses a humidity sensor combined with a heating wire to evaporate the dew. The humidity sensor detects the h...
