Embodiment Construction

[0011] The present invention will be further described below in conjunction with the accompanying drawings.

[0012] Such as figure 1 As shown, the control circuit of this clothes dryer adopts 220V mains electricity transformed by transformer T1 and full-wave rectified by rectifier bridge D1~D4, then filtered by capacitor C1 in turn, stabilized by three-terminal voltage regulator 7812, and filtered by capacitor C2, A DC 12V power supply is obtained for power supply; the 12V power supply is converted by a three-terminal voltage regulator 7805 to obtain a DC 5V power supply for power supply.

[0013] Connect pin 1 of humidity sensor HIH3610 to 5V power supply, pin 2 to one end of resistor R1, and pin 3 to ground; the other end of resistor R1 to one end of capacitor C3 and the positive input end of pin 3 of op amp LM358 chip, and the other end of capacitor C3 to ground ; One end of the adjustable resistor RP is connected to the 5V power supply, the other end is grounded, and the...

Abstract

The invention provides a control circuit with a clothes dryer with a sterilization function. Whether clothes are completely dried or not is judged by arranging a humidity sensor to detect the humidity of an air outlet in the top of the clothes dryer, when the humidity is smaller than a set value, it is shown that the clothes are completely dried, the circuit can automatically switch off power supply of the clothes dryer, and therefore the purposes of automatic timing and electric energy saving are achieved. In the electric heating drying process, an ultraviolet lamp tube is arranged to carry out ultraviolet irradiation sterilization on the wet clothes in the clothes dryer, and therefore the phenomenon that bacteria are bred in wet clothes can be effectively eradicated.

Description

technical field [0001] The invention relates to a control circuit of a clothes dryer, in particular to a control circuit of a clothes dryer with a sterilization function, and belongs to the field of electronic technology. Background technique [0002] A clothes dryer is a cleaning household appliance that uses electric heating to evaporate and dry the moisture in the washed clothes in time. It is especially necessary for the winter in the north and the "returning to the south" in the south where the clothes are difficult to dry. The control circuit of the clothes dryers on the market is relatively simple. Generally, it only provides a mechanical timer, and the user sets the working time of the clothes dryer by himself, and it will end automatically when the time comes. However, this simple control method of the clothes dryer brings a lot of inconvenience to the user. Due to the influence of factors such as different degrees of dryness and wetness of the clothes and the numb...
