Description

A kind of photo-electric control automatic lifting clothes hanger

Technical field:

The utility model relates to the full-automatic lifting clothes airing device that a kind of family, laundry, hospital, hotel are used for airing clothes, particularly a kind of photo-electric control automatic lifting clothes hanger.

Technical background:

The hoisting clothes-horse of switching regulator electric clothes hanger and IR remote controller except that traditional clothes hanger, recent years appearred the hand-rail type hoisting clothes-horse, in existing clothes hanger.Existing these clothing equipment that dries in the air all needs to have brought great inconvenience with the lifting of the direct touch controls clothes hanger of hand to the user, has especially just washed the clothes hand when also wetting as people, and is not only unhygienic but also also have the danger of getting an electric shock for the switching regulator clothes hanger.At present, some have also occurred and utilized wet quick and light sensor work and sunflower-type clothes hanger, but these product structure complexity, cost is higher, and common application is low.In a word, also there is certain defective in its practicality in existing clothes hanger product in general generalization and the security.Especially when higher resident family of floor or architectural airing clothes, directly also there is unsafe factor during the human body operation, will just can finishes the airing action by pole and other objects sometimes.

Summary of the invention:

The purpose of this utility model is to overcome existing clothes hanger needs staff directly to control clothes hanger lifting, easily electric shock, unhygienic and not easy-operating shortcoming, seek a kind of by the contactless control of staff, receive infrared light information by Thermoelectric Infrared Sensor, and utilize timing circuit to control the time that stops when clothes hanger descends, the clothes airing device that shrinks automatically subsequently.

In order to realize the foregoing invention purpose, agent structure of the present utility model comprises inductor, timing control circuit, relay, motor, X type expansion link, halliard and clothes hanger, and wherein timing control circuit is made up of signal amplifier, comparator and electronic control circuit three parts; Rectangular frame formula clothes hanger two ends are shaped on X type expansion link respectively, the upper end of X type expansion link is fixed on ceiling or the supporter, can be wound with halliard on the motor of two-way rotation, lie on the clothes hanger by two X type expansion links respectively, motor is by relay and timing control circuit and inductor electric connection, it rotates to realize control, and the difference that turns to of motor can rise or descend clothes hanger.Timing control circuit comprises devices such as two-stage calculation amplifier, comparator, output control circuit, relay and resistance, electric capacity, transistor, combine by the electrical principles electric connection, its input is connected to inductor, and output is controlled motor operation through relay.Consider actual conditions simultaneously, avoid the people to be not intended to enter into balcony and cause the clothes hanger induction; Inductor is installed in people crown top in the distance of an arm as signal receive section, with guarantee to have only when the people lift hand and hand is placed on half meter of vertical direction with interior induction zone in, inductor just can be sensed infrared ray, starts working; After inductor receives photosignal, it is passed out to operational amplifier, after amplifying through two-stage, again signal is carried out rectifying and wave-filtering and handle, then signal is sent into timing control circuit; The main effect of timing control circuit part is the time lengthening that useful signal is continued, and promptly can stay for some time after clothes hanger drops to certain altitude, to guarantee the user dry in the air article or collect article of time enough is arranged; Timing control circuit is given circuit for controlling motor with useful signal, and circuit for controlling motor mainly contains relay and either-rotation motor is formed, and useful signal is armature of relay adhesive, the motor main story; When having surpassed official hour, useful signal lost efficacy, and movable contact is got back to original position, the motor counter-rotating.

The utility model adopts the IR inductor, place wall to be higher than the people top of the head inductor circuit, when having only the people to stretch out one's hand hand placed in the induction zone (in half meter zone of vertical range), the infrared waves induction that inductor just gives off the people is delivered to timing circuit with signal by filtering, after amplifying then; The inhibit signal of output is succeeded electrical equipment, and by the unlatching of relay control motor, motor load termination expansion link drives the clothes hanger lifting by expansion link; Avoided the people to be not intended to cause the maloperation of inductor through balcony; Adopt the not only steady but also saving space of X type expansion link, expansion link is cast the wave slot type, avoids the clothes move left and right.

Operation principle of the present utility model is that frontend amplifying circuit connects+5V voltage, operational amplifier A 1 and A2 are respectively the one-level amplification and secondary amplifies, A3 is a comparator, when induced signal, after amplifying, signal process A1 and A2 two-stage deliver to comparator A3, this moment, in-phase end voltage was greater than end of oppisite phase, comparator A3 is output as high level, controller CD4538 can export the signal of setting-up time, it is effective that the B pin of controller CD4538 receives the signal of will remaining valid in required time behind the signal, and send it to relay, in the relay because electromagnetic induction, movable contact SA with just changeing a grade adhesive, photodiode VD1 gets the electric signal that sends, the electronic switch KE1 conducting of relay, and motor M obtains three-phase positive phase sequence alternating voltage and starts, and by being rotated in the forward operation, it is minimum that expansion link is dropped to; Behind the blackout, armature is got back to original position, i.e. anti-converting, at this moment, photodiode VD2 gets the electric signal that sends, relay electronic switch KE2 conducting, and motor M obtains three-phase negative-phase sequence alternating voltage and starts, and by the reverse rotation operation, expansion link shrinks, and gets back to original position, and motor quits work.

The utility model compared with prior art has novel structure, and circuit is simple, safe ready, succinct characteristics such as attractive in appearance have avoided human body to contact with the direct of controller, have broad application prospects in family, hospital, dining room, hotel etc., especially have bigger application space in the family expenses field.
