Description

Hand dryer
Technical field
The present invention relates to a kind of lavatory Assisted Facilty, particularly relate to a kind of device that may be used for dry hands.
Background technology
Hand dryer is for drying both hands or drying up the sanitary equipment electrical equipment of both hands between a kind of bathroom, is advanced person, preferably defends Raw cleaning appliance and equipment.It mainly applies to defending of hotel, restaurant, station, airport, scientific research institution, hospital and each family Between life.After washing one's hands, being stretched by both hands under the air outlet of automatic hand dryer, hand dryer can send comfortable wind automatically, makes rapidly Both hands dry exsiccation, and after leaving away, machine is automatically stopped work, it is not necessary to use towel moisture on hand, can prevent disease from intersecting Infect, instead of the utilization of paper simultaneously, there is environmental-protection function.
The basic structure of hand dryer include support, case, motor, heater element, wind wheel (or fan), control circuit plate and Automatically sensing element, case is located on support and constitutes an internally installed space with support, and motor can drive wind wheel to rotate, it is provided that Wind-force, control circuit plate controls to be connected with motor, heater element and automatic sensing element;Aforesaid motor, heater element, electricity Machine, wind wheel and control circuit plate are respectively positioned in case.
The exhaust apparatus of major part hand dryer is to realize heating function by electrical heating, and the wind of motor blowout is through electric power Blow out through exhaust apparatus again after mouth thermal element heating.The i.e. heater element overwhelming majority is all located at air outlet, the acceleration that wind wheel produces Air discharges case through the heater element of air outlet.This kind of design is referred to following patent documentation:
Chinese utility model patent " the constant temp. hand dryer " (Authorization Notice No. of patent No. ZL01252275.9 CN2502305Y), in this patent, heater is located at air outlet.
The Chinese utility model patent " low-noise strong blast volume ultrathin type is done in machine " of Patent No. ZL 200420019768.5 (Authorization Notice No. CN 2673262Y), the air outlet of this patent built with the intersecting parallels calandria woven by heating wire,
Patent No. ZL201220230807.0 " a kind of rustless steel dries sub-device " (Authorization Notice No. CN 202589418 U), The heater of this patent is located in the air-out passage of classification, and air-out passage connects air outlet.
Can Chinese utility model patent " hand dryer " (Granted publication with referenced patent number as ZL201320248414.7 Number it is CN203354447U), in this patent, heating wire is located at air outlet;The China of Patent No. ZL+201320531549.4 is real With new patent " hand dryer high speed ultrathin exhaust apparatus " (Authorization Notice No. is CN 203591216 U), electric power mouth in this patent Thermal element, is arranged between motor and air outlet.
Technique scheme exists following not enough: firstly, since air is quickly through heater, heat time heating time is comparatively short, Integrated air is not heated completely, and air heating out is not very uniform, and some regions are hotter, some regions Temperature is relatively low, to the uncomfortable sensation of people;Secondly, the wind produced by boasting by resistance, thus produces the biggest at heater Noise, and energy loss is bigger;Again, owing to windage is relatively big, hot blast wind speed is slow, and wind-force is little, and the time that dry hands needs is long, In-convenience in use;Finally, when public product institute flow of the people is more, for accelerating to air-dry, user returns close proximity to air outlet, due to Heater is located at air outlet, and careless user exists the risk that finger is burned, and safety has much room for improvement.
It addition, in prior art, generally there is internal structure and arrange it is not quite reasonable in hand dryer, causes volume heavy, account for Problem that is big with locus, that install inconvenience, is shown in the Chinese utility model patent " one is done in device " of ZL 200820084504.6 Authorization Notice No. CN 201164420Y, this patent middle infrared (Mid-IR) wiring board and master control circuit plate are all laid on support, take relatively Big installing space.
Summary of the invention
The technical problem to be solved be provide for the above-mentioned state of the art a kind of leaving air temp uniformly, hands Feel comfortable hand dryer.
To be solved by this invention another technical problem is that provide a kind of noise low for the above-mentioned state of the art and Safe and reliable hand dryer.
The present invention solves the technical scheme that above-mentioned technical problem used: a kind of hand dryer, including
