Abstract

The invention provides a control system of a bathroom exhaust fan. A control unit sends a first signal to the bathroom exhaust fan to turn on the bathroom exhaust fan and sends a second signal to the bathroom exhaust fan to turn off the bathroom exhaust fan. The control unit sends the first signal to the bathroom exhaust fan to turn on the bathroom exhaust fan, and after a first preset waiting time, the control unit sends a third signal to a water heater water outlet temperature measuring unit to start the water heater water outlet temperature measuring unit; when detecting that the water temperature is always lower than a preset temperature in a second preset waiting time, the water heater water outlet temperature measuring unit sends a fourth signal to the control unit; when receiving the fourth signal from the water heater water outlet temperature measuring unit, the control unit sends the second signal to the bathroom exhaust fan to turn off the bathroom exhaust fan.

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.
