The invention provides an automatic clothes dryer control circuit, which comprises a starting unit, a humidity detection and comparison unit, an or logic unit and a power switch unit, wherein the starting unit can delay time and can be reset automatically; output ends of the starting unit and the humidity detection and comparison unit are respectively connected with two input ends of the or logic unit; the output end of the or logic unit controls the power switch unit; and on and off of the main circuit of the clothes dryer are controlled by the switch of the power switch unit. Through detecting humidity of the air outlet at the top part of the clothes dryer, whether the clothes are totally dried can be judged, and when the humidity is lower than a set value, the circuit can automatically disconnect power supply of the clothes dryer, and purposes of automatic time setting and electric energy conservation can be achieved.
Description
Technical field
The present invention relates to a kind of dryer automatic control circuit, belong to electronic technology field.
Background technology
Dryer is a kind of electrical equipment being used for drying clothes, in the common use of southern family.The control circuit of the dryer on market is fairly simple, is generally only to provide a mechanical timer, by user's sets itself dryer working time, then automatically terminates.But this simple control mode of dryer but brings inconvenience to user, due to impact that is different by dryness level of clothes, the not equal factor of clothes quantity, time needed for each drying clothes is different, general user is difficult to accurately estimate needs the setting how long working time just to make clothing dry completely, if timing is too short, then clothes can not parch, if timing is long, causes again unnecessary waste of energy.
Summary of the invention
In order to solve the problem, the invention provides a kind of dryer automatic control circuit, detect the humidity of dryer top outlet inlet with it, when humidity is lower than setting value, automatically disconnects the power supply of dryer, thus reach self-timing and saves energy object.
The concrete technical scheme that the present invention takes is as follows:
A kind of dryer automatic control circuit, it is characterized in that: this circuit comprises start unit, Humidity Detection and comparing unit or logical block and power switch unit, wherein said start unit be one can the automatically reset start unit of time delay, the output terminal of start unit and Humidity Detection and comparing unit accesses or two input ends of logical block respectively, or the output terminal of logical block controls power switch unit, by the break-make of the switch control rule dryer main circuit of power switch unit.
When the present invention uses, Non-follow control start unit, make it to export " 1 " logic state, and then make or logical block output " 1 " logic state, the switch of power switch unit closes, dryer main circuit is connected and is started to carry out drying work, and Humidity Detection and comparing unit also export " 1 " logic state when clothes is not dried, start unit is after certain time-delay, recover to export " 0 " logic state, " 1 " logic state is exported because Humidity Detection and comparing unit maintain, or logical block still exports " 1 " logic state, dryer still normally carries out drying work, pledge clothes after drying, Humidity Detection and comparing unit overturn and export " 0 " logic state, or logical block also overturns output " 0 " logic state, now the switch of power switch unit disconnects automatically, dryer quits work.
Beneficial effect of the present invention is: by the humidity detecting dryer top outlet inlet, this dryer automatic control circuit judges whether clothes dries completely, when humidity is lower than setting value, this circuit can disconnect the power supply of dryer automatically, thus reaches self-timing and saves energy object.
