Description
Technical field
The utility model relates to the electric fan technical field, specifically, is a kind ofly can carry out air draft automatically or regulate the ventilating fan of air draft power automatically according to indoor (kitchen or lavatory) air quality.
Background technique
Ventilating fan is a kind of electrical equipment that generally uses at present.People in the more public place of the stream of people, at home kitchen or lavatory all can install ventilating fan.Because purposes is different, use occasion has difference, so ventilating fan has multiple model, not only power is different, and outward appearance also is distinguishing.
The major function of ventilating fan is to increase the circulation of air in a room, and improves the livable quality of indoor air by " ventilation ".The ventilating fan that is installed in the public place is bigger usually, is mainly used in improving the air quality of public place.The ventilating fan that is installed in the kitchen, house is smaller, is mainly used in getting rid of oil smoke.Be installed in the similar ventilating fan for kitchen use of ventilating fan of lavatory, be mainly used in getting rid of peculiar smell.At present, people to the basic demand of ventilating fan are air draft great efforts, low, the continuous operation for a long time of noise.Present ventilating fan product has satisfied these requirements basically.But problem is that present people just done other things (back especially goes to toilet) after opening ventilating fan, and ventilating fan is heading straight for regard to one often.Ventilate of room do not have any harm to the house certainly yet, but of long duration, can cause waste of electric energy to a certain extent.Therefore, can control the ventilating fan that opens and closes ventilation automatically according to the indoor air situation is that some Consumers welcome.
The model utility content
The purpose of this utility model is to address the above problem, a kind of ventilating fan that can carry out air draft according to IAQ is provided, it utilizes existing sensors technology and electric control technology, monitor IAQ with sensor, pass through the opening and closing of photoelectric conversion structure control ventilating fan again, thereby make ventilating fan can also regulate the power of air draft according to indoor air situation automatic on-off automatically.
For achieving the above object, the utility model has been taked following technological scheme.
A kind of ventilating fan contains ventilating fan, connecting line, switch, it is characterized in that, described ventilating fan is connected with controller by first connecting line; The control and the regulating circuit that the amplification circuit that is made of amplifier and power amplifier are set in described controller, are connected and control by single-chip microcomputer, the gas sensing member that is electrically connected with regulating circuit in the setting of the outside of described controller and described amplification circuit and described control; Described controller is connected with described switch by second connecting line, the automatic control of the controlled and regulating circuit of described switch.
Further, described controller is arranged in the pedestal of ventilating fan, and described gas sensing member is arranged on the outside of ventilating fan pedestal, and described gas sensing member is electrically connected with described controller.
Further, described ventilating fan is by the 220V mains-supplied.
The good effect of a kind of ventilating fan of the utility model is:
(1) because controller can or be installed separately with ventilating fan, so, the mounting point of ventilating fan and highly unrestricted, controller and gas sensing member can be installed in the place that can effectively detect IAQ.
(2) ventilating fan has hand switch and two kinds of control modes of recloser, and two kinds of control modes can intersect automatically and carry out, that is, both can manually open the back and close automatically, can open automatically also that the back is artificial closes.
(3) simple in structure, make easily, easy to use, practical, can satisfy market to the corresponding demand of automatic ventilating fan product.
Description of drawings
Accompanying drawing 1 is the structural representation of a kind of ventilating fan of the utility model.
Accompanying drawing 2 is the electricity work theory diagram of a kind of ventilating fan of the utility model.
Label among the figure is respectively:
1, ventilating fan; 2, first connecting line; 3, controller;
4, gas sensing member; 5, second connecting line; 6, switch.
Embodiment
Provide the embodiment of a kind of ventilating fan of the utility model below in conjunction with accompanying drawing, still, enforcement of the present utility model is not limited to following mode of execution.
Embodiment 1
Referring to accompanying drawing 1, a kind of ventilating fan, contain ventilating fan 1, first connecting line 2, controller 3, gas sensing member 4, second connecting line 5 and switch 6, described ventilating fan 1 can adopt existing ventilating fan structural member, and described first connecting line 2 and second connecting line 5 can be selected existing electric wire for use.Described ventilating fan 1 is connected with controller 3 by first connecting line 2.The length of described first connecting line 2 can be used at random according to actual conditions.Described controller 3 is made of shell and internal structure, the control and the regulating circuit that the amplification circuit that is made of amplifier and power amplifier are set in controller 3 shells, are connected and control by single-chip microcomputer, the gas sensing member 4 that is electrically connected with regulating circuit in the setting of the outside of described controller 3 shells and described amplification circuit and described control.Described controller 3 is connected with described switch 6 by second connecting line 5, the controlled control with regulating circuit of described switch 6, that is and, described switch 6 has manually with controller 3 is automatic controls two kinds of switching modes.
