Description

Hand dryer
Technical field
The utility model is related to a kind of lavatory Assisted Facilty, more particularly to a kind of device that can be used for dry hand.
Background technology
Hand dryer is to be used between a kind of bathroom dry both hands or dry up the sanitary equipment electrical equipment of both hands, is advanced, preferably defends Raw cleaning appliance and equipment.It mainly applies to defending for hotel, restaurant, station, airport, scientific research institution, hospital and each family Between life.After washing one's hands, both hands are stretched under the air outlet of automatic hand dryer, hand dryer can send out comfortable wind automatically, make rapidly Both hands dry exsiccation, and after leaving away, machine is automatically stopped work, without using towel moisture on hand, can prevent disease from intersecting Infection, while the utilization of paper is instead of, with environmental-protection function.
The basic structure of hand dryer include support, case, motor, heater element, wind wheel (or fan), control board and Automatic sensing element, case on the support and constitutes an inside installing space with support, motor can drive wind wheel rotate there is provided Wind-force, control board is connected with the control of motor, heater element and automatic sensing element;Foregoing motor, heater element, electricity Machine, wind wheel and control board are respectively positioned in case.
The exhaust apparatus of most of hand dryer is that heating function is realized by electrical heating, and the wind of motor blowout is through electric power Blown out again through exhaust apparatus after mouth thermal element heating.I.e. the heater element overwhelming majority is all located at air outlet, the acceleration that wind wheel is produced Heater element discharge case of the air through air outlet.This kind of design may be referred to following patent document:
Patent No. ZL01252275.9 Chinese utility model patent《Constant temperature hand dryer》(Authorization Notice No. CN2502305Y), heater is located at air outlet in the patent.
Patent No. ZL 200420019768.5 Chinese utility model patent《Low-noise strong blast volume ultrathin type is done in machine》 (Authorization Notice No. CN 2673262Y), the air outlet of the patent built with the intersecting parallels calandria woven by heating wire,
Patent No. ZL201220230807.0《A kind of stainless steel dries sub- device》(U of Authorization Notice No. CN 202589418), The heater of the patent is located in the air-out passage of classification, air-out passage connection air outlet.
Can be with Chinese utility model patent of the referenced patent number for ZL201320248414.7《Hand dryer》(Granted publication Number it is CN203354447U), heating wire is located at air outlet in the patent;Patent No. ZL 201320531549.4 China is real Use new patent《Hand dryer high speed ultrathin exhaust apparatus》Electric power mouthful in (Authorization Notice No. is the U of CN 203591216), the patent Thermal element, is arranged between motor and air outlet.
Above-mentioned technical proposal exists following not enough:Firstly, since air is quickly through heater, the heat time is shorter, Integrated air is not heated completely, and the air heating come out is not that very uniformly some regions are hotter, some regions Temperature is relatively low, gives people uncomfortable sensation;Secondly, the wind produced by boasting, by resistance, is thus produced very big at heater Noise, and energy loss is than larger;Again, because windage is larger, hot blast wind speed is slow, and wind-force is small, and the time that dry hand needs is long, In-convenience in use;Finally, when public production institute flow of the people is more, to accelerate to air-dry, user is returned close proximity to air outlet, due to Heater is located at air outlet, and careless user has the risk that finger is burned, and security has much room for improvement.
In addition, in the prior art, hand dryer generally existing internal structure arrangement is not quite reasonable, causes volume heavy, accounts for Big with locus, the problem of installing inconvenience sees ZL 200820084504.6 Chinese utility model patent《One kind is done in device》 Authorization Notice No. CN 201164420Y, the patent middle infrared (Mid-IR) wiring board and master control circuit plate are laid on support, take compared with Big installing space.
Utility model content
Technical problem to be solved in the utility model is that to provide a kind of leaving air temp equal for the above-mentioned state of the art Even, comfortable feel hand dryer.
Another technical problem to be solved in the utility model is to provide a kind of noise for the above-mentioned state of the art Low and safe and reliable hand dryer.
The utility model solve the technical scheme that is used of above-mentioned technical problem for:A kind of hand dryer, including
