In the embodiment, the duty ratio of the power-on voltage of the heating device is adjusted in real time by monitoring the temperature and the humidity of the environment, so that the problem that a camera in a refrigerator forms water vapor on a lens to cause an image blur due to the influence of temperature difference when the camera takes a picture in motion can be effectively solved, the resolution and the image recognition rate of the camera are improved, and the power consumption of the camera is reduced. For example, when the temperature and humidity sensor detects that the external environment temperature of the refrigerator is 25 ℃ and the external environment relative humidity is 70%, as can be seen from table 1, the current external environment temperature range is 10 ℃ < Th ≤ 28 ℃, the humidity range is 65% < RH ≤ 75%, and the heating wire energization duty ratio corresponding to the temperature range and the humidity range is 60%, then the display control board can directly obtain a command for controlling the heating wire to operate at an energization duty ratio of 60%, adjust the energization duty ratio of the heating wire in real time, and further control the camera surface temperature, so that the camera surface temperature and the refrigerator external temperature are always kept approximately balanced, and when the refrigerator door is opened for photographing, the problem of fogging of the camera surface is effectively avoided.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
