According to the method for automatically controlling the air-out state of the air conditioner, the light sensor and the temperature sensor are arranged on the outdoor unit, the image recognition module and the temperature and humidity sensor are arranged on the indoor unit, the data information is collected by the microprocessor module and is correspondingly judged and processed to form a control logic, the control instruction is output, and the control module is driven to receive the control instruction sent by the microprocessor, so that the air-out state of the air conditioner is controlled. The respective steps of the present embodiment are described in detail below.
In step S1, judge daytime and night through outdoor light intensity, confirm the wind guide angle of air conditioner air-out, include: a light intensity detection circuit is added on an outdoor unit of an air conditioner, the intensity of light in outdoor environment is converted into a corresponding voltage value or current value through the light intensity detection circuit, a threshold value H is set for the voltage value or the current value, when the voltage value or the current value in the circuit is larger than H, the circuit is judged to be in the daytime, and when the voltage value or the current value is smaller than H, the circuit is judged to be in the night. In some embodiments, the light intensity detection circuit is a light sensitive sensor.
In some embodiments, an image recognition module is added near the air outlet of the air conditioner, so that the direction or the angle V of a human body relative to the air outlet of the air conditioner can be detected, and after the day and night conditions are judged, if the day is in the daytime, namely the voltage value or the current value corresponding to the light intensity is greater than H, the wind guide angle of the air outlet of the air conditioner is determined to be equal to V, and the air outlet of the air conditioner is directly blown to a user; and if the air conditioner is at night, namely the voltage value or the current value corresponding to the light intensity is less than or equal to H, determining that the air guide angle of the air outlet of the air conditioner is not equal to V, and the air outlet of the air conditioner is not blown to a user.
In step S2, the seasonal state is determined according to the outdoor temperature, and the boundary value of the set temperature of the air conditioner is determined, including detecting the outdoor ambient temperature by an ambient temperature sensor of the outdoor unit of the air conditioner, and adding two preset values TSummer (summer)And TWinter season；TSummer (summer)Is an outdoor excessive temperature in summer, TWinter seasonThe temperature is the outdoor supercooling temperature in winter.

when the temperature difference is greater than TA, if the voltage value or the current value corresponding to the light intensity is greater than H, the air conditioner blows high wind; if the voltage value or the current value corresponding to the light intensity is less than or equal to H, the air conditioner blows air;
when the temperature difference is greater than TB and less than or equal to TA, the air conditioner blows air;
when the temperature difference is greater than TC and less than or equal to TB, the air conditioner blows medium and low wind; when the temperature difference is less than TC, the air conditioner blows low wind.
5. The method as claimed in claim 1, further comprising a step S4 of determining whether the air conditioner performs a dehumidifying or humidifying operation according to the indoor humidity condition, comprising:
the humidity sensor is additionally arranged on the indoor unit to detect the humidity of the indoor environment, and the humidity range for human body comfort is set to be H1-H2:
when the humidity is higher than H2, the air conditioner automatically executes the dehumidification operation, and when the indoor humidity HR is (H1+ H2)/2, the dehumidification function is automatically exited;
when the humidity is less than H1, the air conditioner automatically performs the humidification operation, and when the indoor humidity HR is (H1+ H2)/2, the humidification function is automatically exited.
6. The method as claimed in claim 5, wherein the humidification or dehumidification function is preferentially performed when the humidification or dehumidification function conflicts with the air-conditioning cooling or heating mode.
7. The method of claim 1, further comprising:
and step S0, detecting the state of the outdoor light sensor, and judging that the light sensor is in failure when the duration of the state of the outdoor light sensor in daytime or at night is longer than T0 hours, and exiting the day and night detection function.
8. The method according to claim 7, characterized in that self-failover is implemented in case the following conditions are met:
a) the remote controller is used for setting the automatic control function of the air outlet state of the air conditioner again;
b) the abnormality is caused by the duration of the day being longer than T0 hours, and the day and night detection function is recovered when the light sensor detects the night again;
c) the abnormality is caused by the duration of the night being longer than T0 hours, and the day and night detection function is resumed when the light sensor detects a day again.
