Description

A kind of air conditioner electronic speed-regulating switch

The utility model relates to a kind of speed-regulating switch, and refering in particular to is a kind of air conditioner electronic speed-regulating switch.

The central air conditioner system that hotel, dormitory, office building etc. are located, because the user is many, the unified control of inconvenience temperature, therefore, be equipped with a speed-regulating switch to satisfy the needs of user at each user place to indoor temperature control, the present air-conditioning speed-regulating switch that uses, the traditional mechanical type interlock switch of general employing, four knobs are set on switch panel, control power supply respectively, high, medium and low third gear, this switch is because the inner mechanical type that adopts is chain, the contact is many, and reliable in action is poor, brings certain inconvenience to the user; Simultaneously, owing to be to adopt mechanical switch, feel is not good during use.

The purpose of this utility model is to overcome the deficiency of prior art and provides a kind of simple and reasonable, and dependable performance is easy to use, the air conditioner electronic speed-regulating switch that touch feeling is good.

The utility model is to adopt following proposal to realize, it provides pulse signal by anti-flutter pulse generation circuit for integrated package, integrated package is deciphered by the input pulse order, pulse number is distributed three external bidirectional triode thyristor conductings successively of control successively, reach the purpose of control air-conditioning work state.

Concrete structure of the present utility model describes in detail below in conjunction with accompanying drawing:

Accompanying drawing 1 is the utility model electricity theory diagram;

Accompanying drawing 2 is the utility model electrical schematic diagram;

See accompanying drawing 1,2, the utility model is by power circuit 1, anti-flutter pulse generation circuit 2, control circuit 3, switching circuit 4 is formed, 16 pin of ic chip in the one termination control circuit 3 of described power circuit 1, the other end are taken over control shake pulse generating circuit 2,2 pin of ic chip in the output one termination control circuit 3 of anti-flutter pulse generation circuit 2,14 pin of another termination ic chip, the output pin 4,7 of ic chip in the switching circuit 4 difference connection control circuits 3,10, and power circuit 1 is by resistance R 1, R5, diode D1, D2, D3, capacitor C 1 is formed, and anti-flutter pulse generation circuit 2 is turned round K by connecing, resistance R 2, R3, R4, capacitor C 2 is formed, control circuit 3 is made up of ic chip, switching circuit 4 is by resistance R 6, R7, R8, light-emitting diode D4, D5, D6, bidirectional triode thyristor T1, T2, T3 forms.

The model of ic chip is CD4017 in the utility model.

The utility model operation principle is sketched in following: when meeting knob K, to there be pulse signal to act on the counting input end of ic chip, at this moment, ic chip is deciphered according to the order of input pulse, and control successively its 2,4,7,10 pin are exported trigger impulse successively, make light-emitting diode D3, D4, D5, D6 conducting successively is luminous, make bidirectional triode thyristor T1 simultaneously, T2, T3 be conducting successively also, make the sequential loop work of entire circuit by power supply → top gear → mid ranger → low or first gear → shutdown, reach the purpose of control air-conditioning work state, simultaneously, because paired pulses generation circuit has advanced anti-shake processing, when making the utility model work, reliable in action improves greatly, and no misoperation occurs, and has guaranteed the fail safe of using.

In sum, the utility model is simple in structure, dependable performance, and touch feeling is good, convenient processing and manufacture, failure rate is low, can realize industrialized production, is suitable for being particularly suitable for using as the air-conditioning speed governing as the central air conditioner system user as various household electrical appliances speed governing usefulness.
