A hand dryer is a kind of sensor-activated hand drying and cleaning appliance used in bathrooms.
Hand dryers are advanced and ideal hygiene cleaning appliances and equipment in modern times. It is mainly used in hotels, restaurants, scientific research institutions, hospitals, public entertainment venues and bathrooms in every household, etc. After washing your hands, place them under the air outlet of the automatic hand dryer. The automatic hand dryer will automatically send out comfortable warm air to quickly dehumidify and dry your hands. And as soon as you leave the air outlet of the automatic hand dryer, it will automatically stop the air flow and turn off the machine. It can meet the requirements of not drying hands with a towel and preventing cross-infection of diseases.
The hand dryer overcomes the shortcomings of the existing hand dryers that cannot exhaust air in multiple directions and are prone to causing the skin temperature of the hands to be too high. It aims to provide a hand dryer that circulates air in multiple directions. It adopts a technical solution of setting a wind guiding device at the air outlet of the hand dryer, with wind guiding plates on the wind guiding device. Through the rotation of the wind guiding device or the swing of the wind guiding plates, the hand dryer circulates air in an irregular direction.
Working principle
The working principle of a hand dryer is generally that the sensor detects a signal (hand), and this signal controls the opening of the heating circuit relay and the air-blowing circuit relay to start heating and air-blowing. When the signal detected by the sensor disappears, release the contact, and the relays of the heating circuit and the blowing circuit will open, stopping the heating and blowing.
