Abstract
An automatic temperature-adjustment, infrared induction device for drying hands comprises a core control circuit of microprocessor, an infrared induction element, a fan and an electric heating element. A temperature sensor (a thermal resistor) is added on the side of the core control circuit of microprocessor, a temperature-adjustment circuit is added on the side of the fan and is connected to the electric heating element. The utility model can automatically adjust the temperature of the hot wind according to the temperature change of the environment, and the hot wind can be adjusted once again after 30 seconds of wind-out to reduce the temperature of the hot wind. As a result, the user has the feeling of warm all the way, and this device embodies a more humanistic design.
Description
[technical field] the utility model relates to a kind of hand dryer, particularly relates to a kind of non-contacting go out automatically warm braw and the infrared induction hand dryer that closes warm braw and energy automatic temperature-control automatically.
[background technology] is present, and the hand dryer on the market is mostly mainly by air blast, and electroheat member and infrared induction control circuit three parts are formed.The course of work be hot outer control circuit inductance to have object near the time, mainly be meant hand, unlatching air blast and electroheat member power supply, air-flow blows out and acts on hand downwards after heating, to reach the purpose of dried hand.But because of the power of electroheat member is fixed, so the temperature of hot blast does not have too big variation, this point makes that when variation of ambient temperature is big hot blast just can make a world of difference for people's sensation, that is to say, when environment temperature is high, as 6.7 months, hot blast temperature is higher, and sensation scalds one's hand, otherwise as, then feel somewhat cold again in 11.12 months.In addition, in air-dry process, hot blast can not be according to the temperature of the different and appropriate adjustment hot blast of the degree that staff dries up.
[utility model content] task of the present utility model provides a kind of automatic temperature-control infrared induction hand dryer, reaches at different environment temperatures and staff to do the function that wet degree is regulated temperature automatically.
For achieving the above object, the solution that the utility model adopts is, infrared induction parts one side of microcontroller core control circuit has been set up temperature sensor i.e. (thermistor), air blast one side has been set up temperature regulation circuit, this temperature regulation circuit links to each other with described electroheat member, and sensor i.e. (thermistor) links to each other with described microcontroller core control circuit.
The utility model can be regulated hot blast temperature automatically according to the variation of environment temperature, and air-out is after 30 seconds continuously, and hot blast temperature is adjusted once more, reduces hot blast temperature.Allow the user that warm sensation is only arranged from start to finish, embodied more humane design.
[description of drawings]
Each functional module of Fig. 1 automatic temperature-control infrared induction hand dryer.
[specific embodiment] figure one is each functional module of automatic temperature-control infrared induction hand dryer: when the power supply input 200V of automatic temperature-control infrared induction hand dryer alternating current, entire product just is in holding state, the microcontroller core control circuit begins to detect by the infrared induction parts whether object is arranged, mainly be meant hand, near air outlet, just do not continue to detect, if any, the microprocessor reading temperature sensor i.e. (thermistor) detected respective environment temperature and resistance value, read and divide three kinds of situations after the environment temperature: one. when environment temperature is below 5 ℃ the time, microcontroller core control circuit notice temperature regulation circuit removes to drive electroheat member with top grade, and opens air blast simultaneously.Make leaving air temp about 65 ℃; Two. when environment temperature is more than 5 ℃ below 20 ℃ the time, microcontroller core control circuit notice temperature regulation circuit removes to drive electroheat member with middle-grade, and opens air blast simultaneously; Make leaving air temp about 50 ℃; Three. when environment temperature is more than 20 ℃ the time, microcontroller core control circuit notice temperature regulation circuit removes to drive electroheat member with low grade, and opens air blast simultaneously, makes leaving air temp about 35 ℃.This moment, the microcontroller core control circuit continued mainly to be meant hand by infrared induction parts inspected object, whether left air outlet.And pick up counting, when continuous air-out after 30 seconds, hot blast temperature is adjusted once more, reduces hot blast temperature.When detecting object, mainly be meant hand, when leaving air outlet, automatic temperature-control infrared induction hand dryer quits work, and comes back to holding state.
