Abstract
The utility model discloses an exhaust fan control device, which is characterized by comprising a microprocessor, an approach switch and a relay. The approach switch is used for detecting the action of a flush switch; the relay is used for controlling starting and closing of an exhaust fan; both the approach switch and the relay are connected with the microprocessor; and the microprocessor includes a timer used for controlling working time of the exhaust fan. The device has the advantages of automatically starting the exhaust fan after detecting the action of the flush switch and saving energy.
Description
Technical field
The utility model belongs to electronic technology field, relates to a kind of vent fan control device.
Background technology
In average family and the hotel, the vent fan of toilet is by independently circuit control, start and close and all need manual operation, open if when using the toilet, forget, then can not well keep the circulation of air in the toilet, if forget in time after opening and close that then exhaust fan is in and opens and duty, causes energy dissipation always.Therefore, be necessary existing exhaust fan control circuit is transformed.
The utility model content
The utility model wants the technical solution problem to provide a kind of vent fan control device, and this device has and detects the function that automatically starts vent fan after the bath switch motion, also has power saving function.
The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be:
A kind of vent fan control device is characterized in that, comprise microprocessor, be used to detect the bath switch motion near switch, be used to control the relay of vent fan opening and closing; Describedly be connected with microprocessor near switch; The coil of described relay is connected with the output terminal of microprocessor; The normally opened contact of described relay is linked in the current supply circuit of vent fan, and described microprocessor comprises that one is used to control the timer of vent fan working time.
Described near switch be mechanical type near switch or capacitive approach switch, described microprocessor is 51 single-chip microcomputers.
The beneficial effects of the utility model:
The vent fan control device that the utility model provides can be opened exhaust fan by microprocessor by starting relay automatically according to the action of bath switch, also can control exhaust fan by microprocessor and close after time-delay a period of time after the unlatching.Not only can open automatically, can also close automatically, so this vent fan control device having easy to use, energy-conservation effect, is the very useful improvement of carrying out on the basis of existing manual vent fan control circuit.
Description of drawings
Fig. 1 is the theory diagram of vent fan control device.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Embodiment 1:
As Fig. 1, a kind of vent fan control device is characterized in that, comprise microprocessor, be used to detect the bath switch motion near switch, be used to control the relay of vent fan opening and closing; Describedly all be connected with relay with microprocessor near switch; Described microprocessor comprises that one is used to control the timer of vent fan working time.Described near switch be mechanical type near switch or capacitive approach switch, described microprocessor is 51 single-chip microcomputers; The coil of described relay is connected with the output terminal of microprocessor; The normally opened contact of described relay is linked in the current supply circuit of vent fan.
During use, can also connect several buttons, be used to set the parameter of time-delay to microprocessor.Such as being set at 1 minute or 5 minutes.
For this vent fan control device, be that the normally opened contact of relay is inserted in the loop of vent fan, and the switch in parallel of the normally opened contact of this relay and existing vent fan, make manual operation and automatic control to play a role, further facilitate the user and use.
Principle of work of the present utility model is as follows:
Will near switch be installed in the bath switch near, make the action of bath switch can start near switch, the level signal of exporting near switch sends to microprocessor, microprocessor is then by the work of relay startup vent fan, and starts timer work simultaneously.The time of timer setting by the time arrives, and is then closed by relay control vent fan by microprocessor.The coil of microprocessor by the driving circuit pilot relay whether electric, the normally opened contact of relay is concatenated in the loop of exhaust fan, is the technique known that this area is used always.
Claims (2)
1. a vent fan control device is characterized in that, comprise microprocessor, be used to detect the bath switch motion near switch, be used to control the relay of vent fan opening and closing; Describedly be connected with microprocessor near switch; The coil of described relay is connected with the output terminal of microprocessor; The normally opened contact of described relay is linked in the current supply circuit of vent fan, and described microprocessor comprises that one is used to control the timer of vent fan working time.
2. vent fan control device according to claim 1 is characterized in that, described near switch be mechanical type near switch or capacitive approach switch, described microprocessor is 51 single-chip microcomputers.
