Abstract
The invention provides a control system for an exhaust fan of a bathroom. A water heater gas flow measuring unit is arranged at the position of a gas connector of a gas water heater so as to sense the gas flow speed of water at the position of the gas connector. A control unit starts the exhaust fan of the bathroom by sending a first signal to the exhaust fan of the bathroom and stops the exhaust fan of the bathroom by sending a second signal to the exhaust fan of the bathroom. The water heater gas flow measuring unit sends a third signal to the control unit when continuously sensing that the gas flow speed is higher than a first preset speed in a first preset waiting time period. The water heater gas flow measuring unit sends a fourth signal to the control unit when continuously sensing that the gas flow speed is lower than a second preset gas flow speed during a second preset waiting time period. When receiving the fourth signal from the water heater gas flow measuring unit, the control unit sends the second signal to the exhaust fan of the bathroom to stop the exhaust fan of the bathroom.

According to the present invention, provide a kind of bathroom ventilating fan control system, it comprises: control unit and bathroom ventilating fan; Wherein, described control unit is for controlling the opening and closing of described bathroom ventilating fan.
Preferably, described bathroom ventilating fan control system also comprises: gas water-heater and water heater fuel gas flow measuring unit;
Wherein, described water heater fuel gas flow measuring unit is arranged in the combustion gas interface place of described gas water-heater, to sense the airspeed of combustion gas interface place water;
Described gas water-heater is used for using combustion gas as fuel, to be delivered to by heat in the cold water of the heat exchanger flowing through described gas water-heater to prepare hot water by combustion heating mode;
Wherein, described control unit states bathroom ventilating fan by sending the first signal to open to described bathroom ventilating fan, and states bathroom ventilating fan by closing to described bathroom ventilating fan transmission secondary signal;
Described water outlet of water heater measuring unit continue to sense within the first scheduled wait time fuel gas flow speed higher than during predetermined first airspeed to described control single transmit the 3rd signal;
Described water heater fuel gas flow measuring unit continues to sense fuel gas flow speed and sends the 4th signal lower than during the second predetermined air flow speed to described control unit within the second scheduled wait time;
Described control unit is closed to described bathroom ventilating fan transmission secondary signal when receiving the 4th signal from described water heater fuel gas flow measuring unit and is stated bathroom ventilating fan.
Preferably, the described first scheduled wait time is one minute.
Preferably, the described second scheduled wait time is five minutes.
State on the invention in preferred embodiment, gas water-heater is after cut out a period of time, and the fuel gas flow speed of its water heater combustion gas interface starts to become large; Like this, measure airspeed by water outlet of water heater measuring unit 30, then represent that user has opened gas water-heater a period of time when airspeed increases on certain airspeed; If bathroom ventilating fan is not still opened, then represent that user probably forgets and open bathroom ventilating fan, thus system opens bathroom ventilating fan automatically.
Gas water-heater is after cut out a period of time, and the fuel gas flow speed of its water heater combustion gas interface can diminish, close to zero; Like this, measure fuel gas flow speed by water heater fuel gas flow measuring unit, be down under certain airspeed when fuel gas flow speed and then represent that user has closed gas water-heater a period of time; If bathroom ventilating fan is still opened, then represent that user probably forgets and close bathroom ventilating fan, thus system closes bathroom ventilating fan automatically.
Thus, the invention provides and a kind ofly automatically open bathroom ventilating fan when having a bath and forgetting out bathroom ventilating fan and the bathroom ventilating fan control system of a large amount of electric energy of avoiding waste when after a bath to forget afterwards and close bathroom ventilating fan.
Accompanying drawing explanation
By reference to the accompanying drawings, and by reference to detailed description below, will more easily there is more complete understanding to the present invention and more easily understand its adjoint advantage and feature, wherein:
Fig. 1 schematically shows the functional block diagram of bathroom ventilating fan control system according to the preferred embodiment of the invention.
It should be noted that, accompanying drawing is for illustration of the present invention, and unrestricted the present invention.Note, represent that the accompanying drawing of structure may not be draw in proportion.Further, in accompanying drawing, identical or similar element indicates identical or similar label.
Embodiment
In order to make content of the present invention clearly with understandable, below in conjunction with specific embodiments and the drawings, content of the present invention is described in detail.
Fig. 1 schematically shows the functional block diagram of bathroom ventilating fan control system according to the preferred embodiment of the invention.
Specifically, as shown in Figure 1, ventilating fan control system in bathroom comprises according to the preferred embodiment of the invention: control unit 10 and bathroom ventilating fan 20; Wherein, described control unit 10 is for controlling the opening and closing of described bathroom ventilating fan 20.
And as shown in Figure 1, ventilating fan control system in bathroom also comprises according to the preferred embodiment of the invention: gas water-heater 40 and water heater fuel gas flow measuring unit 30.
Wherein, described water heater fuel gas flow measuring unit 30 is arranged in the combustion gas interface place of described gas water-heater 40, to sense the airspeed of combustion gas interface place water.
