Abstract

The utility model discloses a control system and particularly relates to a control system of an induction cooker. The control system comprises a microprocessor module and a heater circuit module, wherein the output of the heater circuit module is connected onto the microprocessor module; a keyboard module is in input connection to the microprocessor module and a display module is in output connection to the microprocessor module at the same time; and an electric leakage protection module is in input connection to the microprocessor module. The technical disadvantage that control systems of induction cookers sold in the market at present do not have an electric leakage protection function is overcome. According to the control system of the induction cooker, the electric leakage protection module in the structure can detect whether an electric leakage condition exists in the induction cooker during working, once the electric leakage protection module detects the electric leakage condition and when the leakage current exceeds a preset value, the electric leakage condition is fed back to the microprocessor module immediately, the microprocessor module can automatically cut off the circuit, the induction cooker stops working, and the usage safety of the induction cooker can be effectively guaranteed.

Description

The control system of electromagnetic oven

Technical field

The utility model relates to the control system of a kind of control system, particularly a kind of electromagnetic oven.

Background technology

Electromagnetic oven has another name called electromagnetic stove, is the product of modern kitchen revolution, and it need not naked light or conduction-type heats and allow heat directly produce in the bottom of a pan, so the thermal efficiency is greatly improved.Be a kind of energy-efficient kitchen utensils, be different from all fire being arranged or heat kitchen tools without the fire conduction of tradition fully.Electromagnetic oven is the electric cooking apparatus that utilizes electromagnetic inductive heating principle to make.Partly formed by high-frequency induction heating coil (being magnet exciting coil), RF power conversion equipment, controller and ferromagnetic material the bottom of a pan cooker etc.During use, pass into alternating current in the heater coil, just produce an alternating magnetic field around the coil, the magnetic line of force of alternating magnetic field is most of by metal pan, produces a large amount of eddy current in the bottom of a pan, thereby produces the required heat of culinary art.In heating process, there is not naked light, so safety, health.

Along with the development of society, microprocessor technology (MCU) is widely used in electromagnetic stove control system equally, and it is intelligent that it can make the control system of electromagnetic oven realize, to meet the modern to the demand of intelligent life style.But electromagnetic stove control system does not in the market all have creepage protection function, and electromagnetic oven belongs to high power electrical equipment, and in a single day it electric leakage situation in use occurs, can bring great harm to user's the security of the lives and property.

Summary of the invention

The purpose of this utility model is to provide a kind of control system with electromagnetic oven of creepage protection function in order to solve above-mentioned the deficiencies in the prior art.

To achieve these goals; the control system of a kind of electromagnetic oven that the utility model is designed; comprise microprocessor module and heater circuit module; the output of heater circuit module is connected on the microprocessor module; simultaneously be connected with Keysheet module and output is connected with display module in the microprocessor module input, also input is connected with leakage protection module on microprocessor module.

Whether the electromagnetic oven in the leakage protection module energy inspection work in the said structure exists the situation of electric leakage; in a single day leakage protection module detects the electric leakage situation; and when leakage current surpasses setting value; it feeds back to microprocessor module immediately; the microprocessor module automatic shutdown circuit, electromagnetic oven just quits work.

For so that the operative intelligence of this control system, the timing that the realizes electromagnetic oven function that boils, also comprise the timing control circuit module in the control system that the utility model provides, be connected by communications serial interface between described timing control circuit module and the microprocessor module, the output of described timing control circuit module connects the heater circuit module.

Also be provided with USB interface described in the utility model on the microprocessor module, cooker can be cooked some e-course and is input in the microprocessor module of this control system, then show by display module, so that the person of boiling can cook according to cooking course, and need not by any other electronic product or culinary art books.

The control system of the electromagnetic oven that the utility model obtains, whether the electromagnetic oven in the leakage protection module energy inspection work in its structure exists the situation of electric leakage, in a single day leakage protection module detects the electric leakage situation, and when leakage current surpasses setting value, it feeds back to microprocessor module immediately, the microprocessor module automatic shutdown circuit, electromagnetic oven just quits work, and effectively guarantees the safety in utilization of electromagnetic oven; The control system of electromagnetic oven in while the utility model, its intelligent degree is high, can realize regularly culinary art, bring convenience to people's life, also have and to input some culinary art e-courses in the microprocessor module in this control system, then show by display module, so that cooker can seen cooking course on one side, cook on one side, but also need not by any other electronic product or books, tradition can not occur and see when TV or books are cooked, cooker is in a rush situation easily.
