Description
Technical field
The utility model relates to a kind of improvement of hand dryer.
Background technology
Automatic hand dryer is advanced and desirable hygiene utensil and equipment.It mainly applies to the toilet etc. of hotel, restaurant, scientific research institution, hospital, place of public amusement and each family.After washing one's hands, stretched by both hands under the air outlet of automatic hand dryer, automatic hand dryer can send comfortable warm braw automatically, makes rapidly your both hands dry exsiccation, and its blowing-out shutdown automatically when you leave hand one in automatic hand dryer air port.Not towel moisture and the requirement preventing cross infection of disease on hand can be reached.
Be applied to now the hand dryer on market, mainly by the effect of sensor, control blower fan high temperature operation, our wet hand is dried rapidly.But because sensor is very easy to damage under long-term humidity effect, cause the life-span of hand dryer not long.
Summary of the invention
The utility model is exactly for the problems referred to above, provides the automatic hand-dryer that a kind of life-span is long.
For achieving the above object, the utility model adopts following technical scheme, the utility model comprises, circuit breaker Q F, time relay KT, transformer T, sensor SQ2, travel switch SQ1, auxiliary reclay KA, fan M, it is characterized in that: the input of circuit breaker Q F connects zero line N and the live wire L of civil power, the fire wire output end of circuit breaker Q F connects normally opened contact end and the transformer T outprimary of auxiliary reclay, the coil-end of the zero line output connect hours relay K T of circuit breaker Q F and primary of transformer end, time relay coil end connects the normally opened contact end of auxiliary reclay KA, one end connecting sensor SQ2 coil-end of transformer T secondary coil, auxiliary reclay KA coil-end and motor M, the motor M other end connect auxiliary reclay KA normally opened contact end, transformer T secondary coil other end connecting sensor SQ2, normally opened contact end travel switch SQ1 one end and auxiliary reclay normally opened contact end, the normally-closed contact end of sensor SQ2 normally opened contact end other end connect hours relay, the normally-closed contact end of the other end connect hours relay of travel switch SQ1.
As a kind of preferred version, described auxiliary reclay is electric current relay.
As another kind of preferred version, described circuit breaker Q F is air switch.
The utility model beneficial effect.
The utility model in use, when sensor SQ2 detects object time, SQ2 normally opened contact closes, then auxiliary reclay KA coil obtains electric, and meanwhile time relay KT is energized and starts timing, the blowing and air blast is started working, when after the time reaching timer, KT normally-closed contact disconnects, KA coil blackout, timer reset, blower fan power-off quits work.When sensor SQ2 is malfunctioning or moisture damage, can time relay KT's closing stroke switch S Q1 be worked.Thus reach and also can use when sensor SQ2 loses efficacy.Thus extend the service life of hand dryer.
Accompanying drawing explanation
The technical problem solved to make the utility model, technical scheme and beneficial effect are clearly understood, below in conjunction with the drawings and the specific embodiments, are further elaborated to the utility model.Should be appreciated that detailed description of the invention described herein only in order to explain the utility model, and be not used in restriction the utility model.
Fig. 1 is the utility model circuit theory diagrams.
Detailed description of the invention
As shown in Figure 1, the utility model comprises, circuit breaker Q F, time relay KT, transformer T, sensor SQ2, travel switch SQ1, auxiliary reclay KA, fan M, it is characterized in that: the input of circuit breaker Q F connects zero line N and the live wire L of civil power, the fire wire output end of circuit breaker Q F connects normally opened contact end and the transformer T outprimary of auxiliary reclay, the coil-end of the zero line output connect hours relay K T of circuit breaker Q F and primary of transformer end, time relay coil end connects the normally opened contact end of auxiliary reclay KA; One end connecting sensor SQ2 coil-end of transformer T secondary coil, auxiliary reclay KA coil-end and motor M, the motor M other end connect auxiliary reclay KA normally opened contact end; Transformer T secondary coil other end connecting sensor SQ2, normally opened contact end travel switch SQ1 one end and auxiliary reclay normally opened contact end, the normally-closed contact end of sensor SQ2 normally opened contact end other end connect hours relay, the normally-closed contact end of the other end connect hours relay of travel switch SQ1.
As a kind of preferred version, described auxiliary reclay is electric current relay.
As another kind of preferred version, described circuit breaker Q F is air switch.
In use, when sensor SQ2 detects object time, SQ2 normally opened contact closes, then auxiliary reclay KA coil obtains electric, and meanwhile time relay KT is energized and starts timing, the blowing and air blast is started working, when after the time reaching timer, KT normally-closed contact disconnects, KA coil blackout, timer reset, blower fan power-off quits work.When sensor SQ2 is malfunctioning or moisture damage, can time relay KT's closing stroke switch S Q1 be worked.
Above content is the further description done the utility model in conjunction with concrete preferred embodiment; can not assert that concrete enforcement of the present utility model is confined to these explanations; for the utility model person of an ordinary skill in the technical field; without departing from the concept of the premise utility; some simple deduction or replace can also be made, all should be considered as belonging to the protection domain that claims that the utility model submits to are determined.
