Description
Technical field
The present invention relates to household appliance technical field, it is more particularly related to a kind of bathroom exhaust fan controls system。
Background technology
Exhaust fan is to be driven fan blade to rotate by motor to drive air-flow, make the spacelike controlled atmosphere electricity-saving appliance that indoor-outdoor air exchanges。Exhaust fan is also known as ventilating fan, ventilation fan etc.。
The purpose of exhaust fan air draft seeks to remove indoor air pollution, regulates temperature, humidity and sensory 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 general all significantly high, this is because the special air-exhausting function of the environment of toilet is critically important。
But, user is when using bathroom exhaust fan, it is possible to there will be the situation after a bath forgetting to close bathroom exhaust fan afterwards。So, if after a bath forgetting afterwards to close bathroom exhaust fan, much electricity can be wasted。
Accordingly, it is desirable to provide the technical scheme of a kind of a large amount of electric energy of avoiding waste when after a bath forgetting to close bathroom exhaust fan afterwards。
Summary of the invention
The technical problem to be solved is for there is drawbacks described above in prior art, it is provided that a kind of bathroom exhaust fan avoiding waste a large amount of electric energy when after a bath forgetting to close bathroom exhaust fan afterwards controls system。
According to the present invention, it is provided that a kind of bathroom exhaust fan controls 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 outlet of water heater measuring unit；
Wherein, described water outlet of water heater measuring unit is arranged in the hot water outlet place of described gas heater, in order to the water velocity at sensing hot water outlet place；
Described gas heater for using combustion gas as fuel, transfers heat to by combustion heating mode to flow through in the cold water of the heat exchanger of described gas heater to prepare hot water；
Wherein, described control unit opens described bathroom exhaust fan by sending the first signal to described bathroom exhaust fan, and closes described bathroom exhaust fan by sending secondary signal to described bathroom exhaust fan；
Described control unit is opening described bathroom exhaust fan and after the first scheduled wait time by sending the first signal to described bathroom exhaust fan, sends the 3rd signal to described water outlet of water heater measuring unit and opens described water outlet of water heater measuring unit；
The 4th signal is sent to described control unit when described water outlet of water heater measuring unit continues to sense water velocity lower than predetermined water velocity within the second scheduled wait time；
Described control unit sends secondary signal when receiving four signals from described water outlet of water heater measuring unit to described bathroom exhaust fan and closes described bathroom exhaust fan。
Preferably, the described first scheduled wait time is one minute。
Preferably, the described second scheduled wait time is five minutes。
Preferably, described hot water outlet place includes and water heater storage cylinder of water is to any position on the flow path between shower head。
In above preferred embodiment of the present invention, gas heater is after cutting out a period of time, and the water velocity of its water heater hot-water outlet can become almost nil；So, measure water velocity by water outlet of water heater measuring unit, be down under certain water velocity when water velocity and then represent that user has been switched off gas heater a period of time；If bathroom exhaust fan is still opened, then it represents that user probably forgets to close bathroom exhaust fan, thus system is automatically switched off bathroom exhaust fan。
Thus, the invention provides a kind of bathroom exhaust fan avoiding waste a large amount of electric energy when after a bath forgetting to close bathroom exhaust fan afterwards and 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 understanding and its adjoint advantage and feature is more easily understood, wherein:
Fig. 1 schematically shows bathroom exhaust fan according to the preferred embodiment of the invention and controls the functional block diagram of system。
It should be noted that accompanying drawing is used for illustrating the present invention, and the unrestricted present invention。Note, represent that the accompanying drawing of structure is likely to be not necessarily drawn to scale。Further, in accompanying drawing, same or like element indicates same or like label。
Detailed description of the invention
In order to make present disclosure clearly with understandable, below in conjunction with specific embodiments and the drawings, present disclosure is described in detail。
Fig. 1 schematically shows bathroom exhaust fan according to the preferred embodiment of the invention and controls the functional block diagram of system。
Specifically, as it is shown in figure 1, according to the preferred embodiment of the invention bathroom exhaust fan control system include: control unit 10 and bathroom exhaust fan 20；Wherein, described control unit 10 is 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 also includes according to the preferred embodiment of the invention: 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 outlet place of described gas heater 40, in order to the water velocity at sensing hot water outlet place。
Wherein it is preferred to, described hot water outlet place includes and water heater storage cylinder of water is to any position on the flow path between shower head。
Described gas heater 40 for using combustion gas as fuel, transfers heat to by combustion heating mode to flow through in the cold water of the heat exchanger of described gas heater 40 to prepare hot water。
Wherein, described control unit 10 opens described bathroom exhaust fan 20 by sending the first signal to described bathroom exhaust fan 20, and closes described bathroom exhaust fan 20 by sending secondary signal to described bathroom exhaust fan 20。
Described control unit 10 is opening described bathroom exhaust fan 20 and through (such as one minute the first scheduled wait time by sending the first signal to described bathroom exhaust fan 20, for waiting that cold water is fully flowed, to prevent follow-up erroneous judgement) after, send the 3rd signal to open described water outlet of water heater measuring unit 30 to described water outlet of water heater measuring unit 30。
