Abstract

The invention provides a bathroom exhaust fan control system. A control unit transmits a first signal to a bathroom exhaust fan to start the bathroom exhaust fan, and transmits a second signal to the bathroom exhaust fan to stop the bathroom exhaust fan. After the control unit transmits the first signal to the bathroom exhaust fan to start the bathroom exhaust fan and waits for preset time, the control unit transmits a third signal to a water heater water outlet temperature measurement unit to start the water heater water outlet temperature measurement unit; the water heater water outlet temperature measurement unit transmits a fourth signal to the control unit when continuously sensing that water temperature is lower than preset temperature within second preset waiting time; the control unit transmits the second signal to the bathroom exhaust fan to stop the bathroom exhaust fan when receiving the fourth signal from the water heater water outlet temperature measurement unit.

Description

technical field [0001] The invention relates to the field of household electrical appliances, and more specifically, the invention relates to a bathroom exhaust fan control system. Background technique [0002] The exhaust fan is a type of air-conditioning appliance that is driven by a motor to rotate the fan blades to drive the airflow to exchange indoor and outdoor air. Exhaust fans are also called ventilation fans, ventilation fans, etc. [0003] The purpose of the exhaust fan is to remove the dirty air in the room and adjust the temperature, humidity and sensory effect.
