Problems solved by technology

Such a structure has the disadvantages of being unsightly, difficult to install, and difficult to clean.
Moreover, the temperature sensor measures the temperature by contacting the cooker. Such a structure is difficult to touch the cooker, resulting in inaccurate temperature measurement.
[0005] 2. The semiconductor temperature sensor has the disadvantages of large measurement temperature error, slow response, short service life, inability to measure high temperature, and easy aging of devices when measuring relatively high temperature.

Embodiment 1

[0038] Embodiment one, cook rice with pressure cooker. Turn on the controller, connect the power supply, and initialize the system. Press button S2 pressure cooker to cook rice function key, integrated circuit IC4 checks that button S2 has been pressed, and immediately sends the key value of S2 to integrated circuit IC3 of microprocessor 4, and integrated circuit IC3 calls the rice cooking function subroutine. The integrated circuit IC3 returns a data to the integrated circuit IC4, and the integrated circuit IC4 drives the nixie tube LED according to the data sent by the integrated circuit IC3 to display the time required for cooking rice for 12 minutes. Simultaneously integrated circuit IC3 sends ignition instruction to electronic igniter (6), and electronic igniter (6) opens solenoid valve (7) and solenoid valve (8), and gas flows to burner through the pipeline of solenoid valve, and flame ignites. At the same time, the integrated circuit IC3 sends an instruction to start t...

Embodiment 2

[0039] Embodiment 2, boiling water: turn on the controller, connect the power supply, and initialize the system. Press the button S1 to boil the water function key, the integrated circuit IC4 inquires that S1 has been pressed, and immediately sends the key value of S1 to the integrated circuit IC3 of the microprocessor 4, and the integrated circuit IC3 calls the boiled water function subroutine. Simultaneously integrated circuit IC3 sends ignition instruction to electronic igniter (6), and electronic igniter (6) opens solenoid valve (7) and solenoid valve (8), and flame is ignited. At the same time, the integrated circuit IC3 sends an instruction to start the A / D converter (3). The thermocouple temperature sensor (1) sends the variation of the water temperature to the operational amplifier (2) for amplification, and then to the A / D converter (3) for analog-to-digital conversion. The microprocessor (4) reads the data change of the A / D converter (3), processes and judges the da...

Embodiment 3

[0040] Embodiment 3, steaming, boiling and stewing dishes with a pressure cooker: open the controller, connect the power supply, and initialize the system. Press button S3 pressure cooker steam, boil, stew function key, integrated circuit IC4 checks button S3 is pressed, immediately sends the key value of button S3 to integrated circuit IC3 of microprocessor 4, integrated circuit IC3 invokes pressure cooker to steam, boil, stew Function key subroutine. The integrated circuit IC3 returns a data to the integrated circuit IC4 of the keyboard display circuit 5, and the integrated circuit IC4 drives the nixie tube LED according to the data sent by the integrated circuit IC3 to display the default required time of 10 minutes. The required time can also be set through S11 and S12. Simultaneously integrated circuit IC3 sends ignition instruction to electronic igniter (6), and electronic igniter (6) opens solenoid valve (7) and solenoid valve (8), and flame is ignited. At the same ti...

Abstract

The invention relates to an intelligent controller used for a gas stove, comprising a thermocouple temperature sensor, a calculation amplifier, an A / D converter, an MPU, a keyboard display circuit, an electronic igniter and two solenoid valve which are electrically connected together. The solenoid valves are arranged on a gas inlet of the stove so as to control the gas flow. Measured temperature signals is sent to the calculation amplifier for amplification by the thermocouple temperature sensor, and after temperature compensating and correcting, the signals are converted into digital signals by the A / D converter and then are sent to the MPU for a treatment. A control program fixed in the MPU controls the electronic igniter, the keyboard display circuit and the A / D converter and simultaneously receives the data coming from the keyboard display circuit and the A / D converter. The solenoid valves are opened or closed by the electronic igniter under the control of the MPU so as to control the gas feeding flow to realize an automatic regulation function of the flame. The automatic flame regulation and temperature control reduce the labor intensity of the user so as to lead the operation to be easy and the using process to be safe and reliable. The invention is suitable for being used as a controller on the gas stove.

Description

technical field [0001] The invention relates to an intelligent controller for controlling a combustion system, especially a gas stove, through an electric device. Background technique [0002] At present, the gas stoves used by people do not have an automatic control device. Therefore, when cooking, stewing or boiling water, people need to pay attention to observation from time to time. When cooking, it is easy to overheat and burn. When stewing, if you don't pay attention a little, you will easily burn the cooking utensils, and the liquid will overflow and drown the flames. Seriously, it will cause safety accidents and bring great inconvenience to people. [0003] According to existing patent technology, temperature sensor is installed on the side of the top gas burner of range body mostly, and adopts semiconductor temperature sensor (as patent CN02254766.5) mostly. There is following deficiency like this: [0004] 1. The temperature sensor is installed on the side of the...
