The invention discloses a bathroom exhaust fan control system. A water heater gas flow measurement unit is distributed at the gas connector of a gas water heater, so as to sense the gas flow speed at the gas connector. A control unit starts a bathroom exhaust fan by sending first signals to the bathroom exhaust fan, and closes the bathroom exhaust fan by sending second signals to the bathroom exhaust fan; after the control unit starts the bathroom exhaust fan by sending the first signals to the bathroom exhaust fan and first preset waiting time later, the control unit sends third signals to the water heater gas flow measurement unit, so as to start the water heater gas flow measurement unit; when the water heater gas flow measurement unit continuously senses that the gas flow speed is lower than a preset gas flow speed during second waiting time, the water heater gas flow measurement unit sends fourth singles to the control unit; the control unit sends the second signals to the bathroom exhaust fan to close the bathroom exhaust fan when receiving the fourth signals from the water heater gas flow measurement unit.
Description
technical field [0001] The present invention relates to the field of household appliances, and more particularly, 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 drive the fan blades to rotate and 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 feeling effect. Exhaust fans are widely used in homes, public places and industrial plants. [0004] The exhaust fan in the bathroom or bathroom is very important, and the installation position of the exhaust fan is generally high, because the special ventilation function of the bathroom environment is very important. [0005] However, when users use the bathroom exhaust fan, they may forget to turn off the bathroom exhaust fan afte...
