10. The method of claim 5,
the first duration and the second duration are equal, or,
the first duration and the second duration are unequal.
11. The method of any of claims 4 to 10, wherein said adjusting the transmittance of said light shielding device behind the panel through hole comprises:
when the light shielding device is started, the light transmittance of the light shielding device behind the through hole of the panel is adjusted to be maximum.
12. An air conditioner, comprising:
a processor;
a memory for storing processor-executable instructions;
a panel with a through hole is arranged on the panel,
the infrared receiving head is arranged behind the through hole and used for sensing infrared remote control signals;
the light-shielding device with adjustable light transmittance is arranged between the through hole and the infrared receiving head;
wherein the processor is configured to:
and adjusting the light transmittance of the light shielding device behind the through hole of the panel according to the infrared remote control signal so as to shield invalid infrared interference signals.
