In a specific embodiment, the n=3, that is, the integrated function module 2 is controlled to rotate forward and reverse alternately, for a total of 3 rotations, so as to scrape off the condensation on the glass cover 23 .

Further, after "driving the integrated function module 2 to move", the control method further includes the following steps: controlling the heating wire on the glass cover 23 to start.

After "controlling the heating wire on the glass cover 23 to start", the user can directly perform a touch operation on the touch interface of the projection area for human-computer interaction.

Further, after the user touch operation is completed, the control method of the cooling device 100 further includes the following steps: driving the integrated function module 2 to move to the lighting module 6 and starting the lighting module 6 after one of the multiple windows 4 is exposed .

Specifically, the aforementioned "one of the plurality of windows 4" specifically refers to the window 4 among the plurality of windows 4 corresponding to the area to be lit.

In the state of opening the door, the above-mentioned area to be lit is the area to be accessed. That is, the area to be accessed is obtained according to the user's touch operation, and after the user's touch operation is completed, the integrated function module 2 is driven to move to the lighting module 6 to be exposed from the window 4 corresponding to the area to be accessed.

Further, "starting the lighting module 6" specifically includes the following steps:

Control the lighting module 6 to light up with the first luminous power;

Judging whether the light in the area to be lit meets the requirements; if not, then controlling the luminous power of the lighting module 6 to switch to a second luminous power, wherein the second luminous power is greater than the first luminous power.

In the state of opening the door, the above-mentioned "judging whether the light in the area to be lit meets the requirements" is specifically to judge whether the light in the area to be lit meets the user's viewing requirements. It is known that the light is too dark for the user to clearly Seeing the situation of the area to be accessed, at this time, it is necessary to control the luminous power of the lighting module 6 to switch to the second luminous power, so as to increase the luminous brightness of the lighting module 6, which is convenient for the user to view and access items.
