The heat sensitive luminous element can be PTC (Positive Temperature Coefficient) ceramic luminous element for heating air temperature. The ultraviolet light emitting element is used for air sterilization.
The control method of the lower air outlet air conditioner comprises the following steps:
step S1: the temperature sensor acquires the air temperature in the middle of the bottom of the room, and if the air temperature in the middle of the bottom of the room is at the preset temperature, the number of the luminous bulbs is controlled according to the air temperature in the middle of the bottom of the room.
Step S2: if the air temperature in the middle of the bottom of the room is lower than the preset temperature, the temperature sensor acquires the air temperature at the lower end of the bottom of the room, and the number of the luminous bulbs is increased according to the air temperature at the lower end of the bottom of the room.
Step S3: if the air temperature in the middle of the bottom of the room is higher than the preset temperature, the temperature sensor acquires the air temperature at the upper end of the bottom of the room, and the number of the luminous bulbs is reduced according to the air temperature at the upper end of the bottom of the room.
After the user selects the warm air function, the main control module 4 sends a signal to the warm air control module 2, and after receiving the signal, the warm air control module 2 can control all the temperature sensors 1 to simultaneously start measuring the air temperature of the room, and each temperature sensor 1 can acquire the air temperature of different heights of the room.

The heat sensitive light emitting element in the light emitting bulb 3 can effectively heat the air, and the ultraviolet light emitting element can sterilize the air.
According to the distribution characteristic of the air temperature, the air temperature at the lower end of the bottom of the room is reduced from top to bottom in sequence when no other factors influence, so that the temperature of the whole bottom is maintained stable and the temperature of the bottom of the room is prevented from being too low. In the control process, if the air temperature in the middle of the bottom of the room is at the preset temperature, the number of the light-emitting bulbs 3 is controlled to be started according to the air temperature in the middle of the bottom of the room. If the air temperature in the middle of the bottom of the room is lower than the preset temperature, the air temperature at the lower end of the bottom of the room is obtained, and the number of the luminous bulbs 3 is increased according to the air temperature at the lower end of the bottom of the room.
