Feel effect.Exhaust fan is widely used in family, public place and industrial premises.
The exhaust fan in toilet or bathroom is critically important, and exhaust fan installation site is the highest, this
The special air-exhausting function of environment being because toilet is critically important.
But, user, when having a bath, may forget open bathroom exhaust fan, thus the use having a bath
Family may feel that airtight etc sense of discomfort.
Secondly, user is when using bathroom exhaust fan, it is possible that forget the most afterwards to close bathroom
The situation of exhaust fan.So, if forgetting the most afterwards to close bathroom exhaust fan, a lot of electricity can be wasted
Energy.
Accordingly, it is desirable to provide one automatically turns on bathroom exhaust fan when having a bath and forgetting out bathroom exhaust fan
And the technology of a large amount of electric energy of avoiding waste in the case of forgetting the most afterwards to close bathroom exhaust fan
Scheme.
Summary of the invention
The technical problem to be solved is for there is drawbacks described above in prior art, it is provided that one
Plant and automatically turn on bathroom exhaust fan when having a bath and forgetting out bathroom exhaust fan and forgetting the most afterwards
Avoid waste in the case of closing bathroom exhaust fan the bathroom exhaust fan control system of a large amount of electric energy.
According to the present invention, it is provided that a kind of bathroom exhaust fan control system, comprising: control unit and
Bathroom exhaust fan；Wherein, described control unit is for controlling the opening and closing of described bathroom exhaust fan.
Preferably, described bathroom exhaust fan control system also includes: gas heater and water heater go out
Water gaging unit；
Wherein, described water outlet of water heater measuring unit is arranged in the hot water outlet of described gas heater
Place, in order to the water velocity at sensing hot water outlet；
Described gas heater is for using combustion gas as fuel, transmitting heat by combustion heating mode
To prepare hot water in the cold water of the heat exchanger flowing through described gas heater；
Wherein, described control unit is opened described by sending the first signal to described bathroom exhaust fan
Bathroom exhaust fan, and close described bathroom row by sending secondary signal to described bathroom exhaust fan
Fan；
Described water outlet of water heater measuring unit persistently senses water flow velocity within the first scheduled wait time
Degree sends the 3rd signal higher than during predetermined water velocity to described control unit；
Described water outlet of water heater measuring unit persistently senses water flow velocity within the second scheduled wait time
Degree sends the 4th signal less than during predetermined water velocity to described control unit；
Described control unit from described water outlet of water heater measuring unit receive three signals time to described
Bathroom exhaust fan sends the first signal to open described bathroom exhaust fan；
Described control unit from described water outlet of water heater measuring unit receive four signals time to described
Bathroom exhaust fan sends secondary signal and closes described bathroom exhaust fan.
Preferably, include at described hot water outlet and water heater storage cylinder of water is to the current between shower head
Any position on path.
Preferably, the first scheduled wait time was five minutes.
Preferably, the second scheduled wait time was five minutes.
In the present invention, gas heater opening after a period of time, its water heater hot-water outlet
Water velocity start to become big；So, measure water velocity by water outlet of water heater measuring unit, when
Water velocity increases to then represent on certain water velocity that user has been switched on gas heater one section
Time；If bathroom exhaust fan is still not turned on, then it represents that user probably forgets to turn on
Bathroom exhaust fan, thus system automatically turns on bathroom exhaust fan.
And, gas heater closing after a period of time, the current of its water heater hot-water outlet
Speed can become almost nil；So, measure water velocity by water outlet of water heater measuring unit, when
Water velocity is down under certain water velocity then represent when user has been switched off gas heater one section
Between；If bathroom exhaust fan is still opened, then it represents that user probably forgets to close bathroom row
Fan, thus system is automatically switched off bathroom exhaust fan.
Thus, the invention provides a kind of bathroom that automatically turns on when having a bath and forgetting out bathroom exhaust fan to arrange
Fan and a large amount of electric energy of avoiding waste in the case of forgetting the most afterwards to close bathroom exhaust fan
Bathroom exhaust fan control system.
Accompanying drawing explanation
In conjunction with accompanying drawing, and by with reference to detailed description below, it will more easily the present invention is had more
Complete understands and its adjoint advantage and feature is more easily understood, wherein:
Fig. 1 schematically shows bathroom exhaust fan control system according to the preferred embodiment of the invention
Functional block diagram.
It should be noted that accompanying drawing is used for illustrating the present invention, and the unrestricted present invention.Note, represent
The accompanying drawing of structure may be not necessarily drawn to scale.Further, in accompanying drawing, same or like element mark
There is same or like label.
Detailed description of the invention
In order to make present disclosure more clear and understandable, below in conjunction with specific embodiments and the drawings pair
Present disclosure is described in detail.
Fig. 1 schematically shows bathroom exhaust fan control system according to the preferred embodiment of the invention
Functional block diagram.
Specifically, as it is shown in figure 1, according to the preferred embodiment of the invention bathroom exhaust fan control system
System includes: control unit 10 and bathroom exhaust fan 20；Wherein, described control unit 10 is used for controlling
The opening and closing of described bathroom exhaust fan 20.
And, as it is shown in figure 1, bathroom exhaust fan control system is also according to the preferred embodiment of the invention
Including: gas heater 40 and water outlet of water heater measuring unit 30.
Wherein, described water outlet of water heater measuring unit 30 is arranged in the hot water of described gas heater 40
Water outlet, in order to the water velocity at sensing hot water outlet.
Wherein it is preferred to, include at described hot water outlet and water heater storage cylinder of water is between shower head
Flow path on any position.
