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

[0036] Embodiment one, cook rice with pressure cooker. Turn on the controller, connect the power supply, and initialize the system. Press the key switch S2 pressure cooker rice cooking function key, the integrated circuit IC4 inquires that the key switch S2 has been pressed, and immediately sends the key value of the key switch S2 to the integrated circuit IC3 of the microprocessor 4, and the 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. At the same time, the integrated circuit IC3 sends an ignition command to the electronic igniter 6, and the electronic igniter 6 opens the first electromagnetic valve 7 and the second electromagnetic valve 8, and the gas flows through the pipeline of the electromagnetic valve ...

Embodiment 2

[0037] Embodiment 2, boiling water: turn on the controller, connect the power supply, and initialize the system. Press the key switch S1 to boil the water function key, the integrated circuit IC4 inquires that the key switch S1 has been pressed, and immediately sends the key value of the key switch S1 to the integrated circuit IC3 of the microprocessor 4, and the integrated circuit IC3 calls the boiling water function subroutine. At the same time, the integrated circuit IC3 sends an ignition command to the electronic igniter 6, and the electronic igniter 6 opens the first electromagnetic valve 7 and the second electromagnetic valve 8, and the flame is lit. 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 th...

Embodiment 3

[0038] Embodiment 3, steaming, boiling and stewing dishes with a pressure cooker: open the controller, connect the power supply, and initialize the system. Press the key switch S3 pressure cooker steaming, boiling, stewing function key, the integrated circuit IC4 inquires that the key switch S3 is pressed, and immediately sends the key value of the key switch S3 to the integrated circuit IC3 of the microprocessor 4, and the integrated circuit IC3 calls the 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 the key switches S11 and S12. At the same time, the integrated circuit IC3 sends an ignition command to the electronic igniter 6, and the electronic ign...

Abstract

An intelligent controller for a gas stove comprises a thermocouple temperature sensor, an operational amplifier, an A / D converter, a microprocessor, a keyboard display circuit, an electronic igniter, and two solenoid valves electrically connected. Electromagnetic valve is installed on the air inlet of kitchen range body, and its effect is the flow of controlling gas. The temperature signal measured by the thermocouple temperature sensor is sent to the remote computing amplifier for amplification, and the temperature compensation is corrected. The signal is converted into a digital signal by the A / D converter and then sent to the microprocessor for processing. The electronic igniter, the keyboard display circuit and the A / D converter are controlled by the control program compiled in the microprocessor, and the data sent by the A / D converter and the keyboard display circuit are simultaneously received. The electronic igniter opens or closes the solenoid valve under the control of the microprocessor, thereby controlling the flow of gas intake and realizing the function of automatic flame adjustment. Automatic fire adjustment and temperature control, reducing the labor intensity of the operator, easy to operate, safe and reliable to use, suitable for use as a controller on a 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...
