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 for drying clothes, commonly used in southern family.The control of the dryer of in the market
Circuit processed is fairly simple, typically just provides a mechanical timer, by user's sets itself dryer working time, then from
It is dynamic to terminate.But this simple control mode of dryer but brings inconvenience to user, due to by dryness level of clothes not
The influence of the factors such as same, clothes quantity difference, the time needed for each drying clothes is different, and general user is difficult accurately to estimate
Amount needs to set that the working time how long just could be such that clothing dries completely, if timing is too short, clothes can not parch, if fixed
When it is long, cause unnecessary waste of energy again.
The content of the invention
In order to solve the above problems, the invention provides a kind of dryer automatic control circuit, and dryer top is detected with it
The humidity of portion's air outlet, when humidity is less than setting value, the automatic power supply for disconnecting dryer, so as to reach self-timing and saving
Electric energy purpose.
The concrete technical scheme that the present invention is taken is as follows：
A kind of dryer automatic control circuit, it is characterized in that：It is single compared with that the circuit includes start unit, Humidity Detection
Member or logic unit and power switch unit, wherein the start unit is the automatically reset start unit that can be delayed, are opened
Moving cell and Humidity Detection and the output end of comparing unit are respectively connected to or two inputs of logic unit, or logic unit
Output end controls power switch unit, and the break-make of dryer main circuit is controlled by the switch of power switch unit.
The present invention is allowed to export " 1 " logic state in use, control start unit manually, and then makes or logic unit is defeated
Go out " 1 " logic state, the switch closure of power switch unit, dryer main circuit, which is connected, proceeds by drying work, and humidity
Detection also exports " 1 " logic state when clothes is not dried with comparing unit, and start unit recovers output after certain time-delay
" 0 " logic state, because Humidity Detection and comparing unit maintain output " 1 " logic state, or logic unit still to export " 1 " and patrol
The state of collecting, dryer is still normally carried out drying work, after drying of pledging clothes, Humidity Detection and comparing unit upset output " 0 "
Logic state, or logic unit also overturn output " 0 " logic state, and now the switch of power switch unit disconnects automatically, drying
Machine is stopped.
Beneficial effects of the present invention are：This dryer automatic control circuit is by detecting the humidity of dryer top outlet inlet
To judge whether clothes dries completely, when humidity is less than setting value, this circuit can disconnect the power supply of dryer automatically, so as to reach
To self-timing and save electric energy purpose.
Brief description of the drawings
Fig. 1 is the theory diagram of the present invention.
Fig. 2 is the physical circuit figure of the present invention.
Embodiment
The present invention will be further described below in conjunction with the accompanying drawings.
As shown in figure 1, this dryer automatic control circuit includes start unit, Humidity Detection and comparing unit or logic
