Microwave is a kind of electromagnetic wave.Micro-wave oven is made up of power supply, magnetron, the part such as control circuit and cooking cavity.Power supply
About 4000 volts of high pressures are provided to magnetron, magnetron continuously generates microwave under power supply excitation, then by Wave guide system, coupling
Close in cooking cavity.Near the entrance of cooking cavity, there is a rotatable agitator, because agitator is the gold of fan-shaped
Category, has the reflection of all directions, so microwave energy can be evenly distributed in cooking cavity to microwave after rotating
It is interior, so as to heat food.The power bracket of micro-wave oven is generally 500~1000 watts.
Certain defect during use be present in existing microwave oven control system：It is micro- with the continuous development of society
Processor technology（MCU）It has been similarly obtained and has been widely applied in microwave oven control system, it can makes the control system of micro-wave oven
Intellectuality is realized, to meet demand of the modern to intelligent life style.But microwave oven control system in the market
There is no creepage protection function, and micro-wave oven belongs to high power electrical equipment, it, can be to making once in use occur drain conditions
The security of the lives and property of user brings great harm.
The content of the invention
It is an object of the invention to provide a kind of micro-wave oven earth leakage protective control system, to solve to carry in above-mentioned background technology
The problem of going out.
To achieve the above object, the present invention provides following technical scheme：A kind of micro-wave oven earth leakage protective control system, including
Keyboard, display, microprocessor, heater circuit module, leakage protection module and control and detection circuit module, the heating electricity
On the microprocessor, the first input end of the microprocessor is connected with keyboard, and the microprocessor for road module output end connection
Second input of device is connected with display screen, and the 3rd input of the microprocessor is connected with leakage protection module, the leakage
The output end of electric protection module is connected with control and detection circuit module.
Preferably, the display is LCDs, and the size of the LCDs is 4 inches.
Preferably, the microprocessor is single-chip microcomputer, the model AT89S52 of the single-chip microcomputer.
Preferably, the detection upper voltage limit value of the leakage protection module is 36V.
Compared with prior art, the beneficial effects of the invention are as follows：
The control system for the micro-wave oven that invention obtains, the leakage protection module in its structure can check micro- in work
For ripple stove with the presence or absence of the situation of electric leakage, leakage protection module once detects drain conditions, and when electrical leakage voltage exceedes setting value,
It feeds back to microprocessor module immediately, and microprocessor module sends electric signal and automatically cuts off electricity to control and detection circuit module
Road, micro-wave oven are just stopped, and effectively ensure use of microwave ovens security, avoid people from getting an electric shock and contingency occur, use
It is more safe and reliable.
