Inductive multistratum control system of hand dryer

Abstract

The invention relates to an inductive multistratum control system of a hand dryer, in particular to a control system which is usually arranged in a toilet, generates heat and wind through power to dry hands of a human and improves the hand dryer incapable of controlling the wind rate and the temperature in real time. The hand dryer comprises a heater, a blade motor and an induction unit and is characterized in that the induction unit is at least provided with two groups of induction sets arranged at an air outlet of the hand dryer and is electrically connected with a control circuit capable of turning on and off the heater and the blade motor and controlling the temperature of the heater and the rotation speed of the blade motor, thereby forming the inductive multistratum control system. The over two groups of induction sets are matched with a comparing and logic processor to process a signal, thus the control circuit has the function of the multistratum control of the temperature of the heater and the rotation speed of the blade motor, and the aim that the user can easily, rapidly, hygienically and safely operates the wind rate and the temperature can be achieved.

Description

technical field [0001] The invention relates to a device for drying wet objects, in particular to a hand dryer control system permanently installed in a bathroom to dry human hands by generating heat and wind through electricity. Background technique [0002] In daily life, after washing your hands in public spaces such as stations, office buildings, companies, factories, hotels, restaurants, or hypermarkets, you often dry your hands with paper towels provided by public toilets or with your own paper towels or handkerchiefs ; But in fact, often because the tissues provided by the public toilets are exhausted or they forget to bring them by themselves, they have to let the hands dry naturally or dry in the shade, which is more likely to be contaminated with bacteria and unhygienic for wet hands Therefore, based on the above-mentioned needs, some operators have developed a "hand dryer" product to respond to the user's need to quickly dry their hands after washing their hands i...

AI Technical Summary

Problems solved by technology

[0004] 1. The control method is not safe; since the user's hands are wet before drying, they have excellent electrical conductivity and the possibility of electric shock, so wet hands can easily form good conductors and cause the risk of electric shock

[0005] 2. The control method does not meet the hygienic requirements of modern people; since the hand dryer is operated by pressing the touch switch, it is very likely that there will be a chance of infection due to contact with the touch switch.

[0008] 1. There is no function to control the air volume and temperature of the hand dryer; because the installation of the hand dryer will vary from time to place and from person to person, there will be different requirements for air volume and temperature, most obviously in winter and summer Temperature changes, which means that users have obvious differences in temperature requirements; therefore, if the hand dryer cannot control its air volume and temperature, it does not meet the needs of users

[0009] 2. Because there is no function to control the air volume and temperature of the hand dryer, it will not have the additional function of prompting the air volume and temperature
