AI Technical Summary

Technical Problem

During the stove manufacturing process, installation errors in the magnetic coding chip can cause knob angle deviations. In particular, stoves powered by dry batteries cannot be manually calibrated when the power is off, making it impossible for users to accurately obtain the initial position of the knob.

Method used

By acquiring the start and finish times when the magnetic encoder is powered on, calculating the rotational angular velocity and deviation angle, determining the standard angle of the stove knob's off position, and setting a calibration mark, the knob angle is calibrated.

Benefits of technology

When powered by dry cell batteries, the initial position of the stove knob is accurately calibrated, solving the problem of magnetic encoder installation error and ensuring the accuracy of the stove knob angle.

Abstract

This application relates to a method for calibrating the knob angle of a gas stove and a gas stove, belonging to the field of gas stove technology. The method includes: acquiring the power-on start time of the magnetic encoder when it is powered on; acquiring the power-on completion time and a first knob angle corresponding to the power-on completion time when the magnetic encoder is powered on; and acquiring the current operating time of the magnetic encoder when the difference between the second knob angle output by the magnetic encoder and the first knob angle is detected to be a preset angle threshold; determining the deviation angle of the magnetic encoder based on the power-on start time, the power-on completion time, the angle threshold, and the current operating time; determining the standard angle of the off position of the gas stove knob based on the first knob angle and the deviation angle, and setting a calibrated mark for the standard angle of the off position. This application can be used to calibrate the knob angle of a gas stove.
