Problems solved by technology

Although the photosensitive function is an additional function, if the photosensitive sensor fails, it will cause abnormal operation of the home appliance system. For example, the photosensitive sensor may break down and short circuit during work, which will directly affect the normal operation of the home appliance.
However, related technologies cannot judge whether the photosensitive sensor is faulty

Abstract

The invention discloses an air conditioner and a self-detection device and a self-detection method for a photosensitive sensor in the air conditioner. The self-detection device comprises the photosensitive sensor, a first switch, a first resistor, a second switch, a second resistor and a controller, wherein one end of the photosensitive sensor is connected with a power supply; one end of the first switch is connected with the other end of the photosensitive sensor; one end of the first resistor is grounded, and the other end of the first resistor is connected with the other end of the first switch; one end of the second switch is connected with the other end of the photosensitive sensor; one end of the second resistor is grounded, and the other end of the second resistor is connected with the other end of the second switch; the controller is connected with a control end of the first switch, a control end of the second switch and the other end of the photosensitive sensor, and is used for controlling closing of the first switch and opening of the second switch, acquiring second detection voltage and judging whether the photosensitive sensor fails according to the second detection voltage. Thus, whether the photosensitive sensor fails is effectively judged through self-detection on hardware.

Description

technical field [0001] The invention relates to the technical field of electric appliances, in particular to a self-checking device of a photosensitive sensor in an air conditioner, an air conditioner and a self-checking method of the photosensitive sensor in the air conditioner. Background technique [0002] Light-sensitive sensors are widely used in mobile phones to adjust the brightness of the display screen. With the gradual improvement of the functions of the home appliance industry, photosensitive sensors are also applied to home appliances. Although the photosensitive function is an additional function, if the photosensitive sensor fails, it will cause abnormal operation of the home appliance system. For example, the photosensitive sensor may break down and short circuit during work, which will directly affect the normal operation of the home appliance. However, related technologies cannot determine whether the photosensitive sensor is malfunctioning. Contents of t...
