Therefore, desirable to provide a kind of technological scheme of a large amount of electric energy of avoiding waste when after a bath forgetting afterwards and close bathroom ventilating fan.
Summary of the invention
Technical problem to be solved by this invention is for there is above-mentioned defect in prior art, provides a kind of bathroom ventilating fan control system of a large amount of electric energy of avoiding waste when after a bath forgetting afterwards and close bathroom ventilating fan.
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 control unit is being opened described bathroom ventilating fan by sending the first signal to described bathroom ventilating fan and after the first scheduled wait time, is sending the 3rd signal open described water heater fuel gas flow measuring unit to described water heater fuel gas flow measuring unit;
Described water heater fuel gas flow measuring unit continues to sense fuel gas flow speed and sends the 4th signal lower than during 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 can turn cold; 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 a kind of bathroom ventilating fan control system of a large amount of electric energy of avoiding waste when after a bath forgetting 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.
Heat for using combustion gas as fuel, to be delivered to by combustion heating mode in the cold water of the heat exchanger flowing through described gas water-heater 40 to prepare hot water by described gas water-heater 40.
Wherein, described control unit 10 states bathroom ventilating fan 20 by sending the first signal to open to described bathroom ventilating fan 20, and states bathroom ventilating fan 20 by sending secondary signal to close to described bathroom ventilating fan 20.
