Detailed Description
The present invention is illustrated by the following examples, but the present invention is not limited to these examples. Modifications to the embodiments of the invention or equivalent substitutions of parts of technical features without departing from the spirit of the invention are intended to be covered by the scope of the claims of the invention.
Referring to the attached drawing 1, the gear judgment method of a stove disclosed by the invention comprises a valve body, a magnetic encoder and a controller, wherein the valve body is provided with a valve core and a rotating shaft connected with the valve core, a magnet is arranged on the valve core, the magnetic encoder is matched with the magnet to read an angle value of the valve core, the controller is electrically connected with the magnetic encoder, and the gear judgment method comprises the following steps: reading a calibration initial angle value S1 of a set gear of the valve body; reading an absolute angle value S2 of a current gear of the valve body; calculating a relative angle value S3 of the current gear of the valve body according to the calibration initial angle value and the absolute angle value; and judging the current gear S4 of the valve body according to the relative angle value. Because the positions of north and south poles of each magnet may be different, and different batches of magnets may also be different, one magnet is installed in the valve body, and the rotation angle and the corresponding gear are set as a standard gear distribution, referring to the figure, the standard gear distribution in the embodiment is shown, and the distribution of each gear in the standard gear distribution is: first gear corresponds to 0 degree, second gear corresponds to 30 degrees, third gear corresponds to 60 degrees, fourth gear corresponds to 90 degrees, fifth gear corresponds to 120 degrees, sixth gear corresponds to 150 degrees, seventh gear corresponds to 180 degrees, 75 degrees are arranged between seventh gear and OFF gear, 255 degrees are arranged between OFF gear and first gear, and 105 degrees are arranged between OFF gear and first gear. Wherein there is no fire between OFF and first gear. After the valve body is fired, when the valve body passes through a first gear clockwise, namely, the firepower output is a first gear until the valve body passes through a second gear, when the valve body is between the first gear and the second gear, the firepower output is still the first gear without passing through the second gear, and if the valve body passes through the second gear clockwise, the firepower is changed into the second gear.
In this embodiment, the difference of the fire gears represents the difference of the fire power, and the fire power can be gradually increased from the first gear to the seventh gear or gradually decreased from the first gear to the seventh gear.
The calibration initial angle value of the set gear of the valve body is obtained by the following steps: entering a gear calibration mode, and rotating the valve body to a set gear; the controller reads the angle value read by the magnetic encoder; the controller records and saves the angle value of the set gear as a calibration initial angle value.
The set gear may be any of first to seventh gears, and in the present embodiment, the set gear is first gear. And before leaving the factory, calibrating the valve body. Entering a calibration mode, rotating the valve body to a set gear, reading a calibration initial angle value of the set gear of the valve body by the controller, reading an angle value of a first gear in the embodiment, and recording and storing the calibration initial angle value of the first gear by the controller if the angle value of the first gear read by the controller is 30 degrees, namely the calibration initial angle value of the first gear is 30 degrees. That is, the valve body has a deviation of 30 degrees with respect to 0 degrees corresponding to the first gear in the standard gear distribution.
When a user uses the cooker, the valve body is twisted to an absolute angle value, and if the user rotates the valve body to 100 degrees, the absolute angle value is 100 degrees.
The step of calculating the relative angle value of the current gear of the valve body specifically comprises the following steps: judging whether the absolute angle value is larger than the calibration initial angle value; if the absolute angle value is greater than the calibration initial angle value, the relative angle value is equal to an absolute angle value-a calibration initial angle value; if the absolute angle value is smaller than the calibration initial angle value, the relative angle value is equal to the absolute angle value +360 degrees-the calibration initial angle value. If the calibration initial angle value is 30 degrees, the absolute angle value is 100 degrees, the absolute angle value is larger than the calibration initial angle value, and the relative angle value is 70 degrees to 100-30 degrees. If the initial calibration angle value is 100 degrees, the absolute angle value is 30 degrees, and the absolute angle value is smaller than the initial calibration angle value, the relative angle value is 30+ 360-100-290 degrees.
And judging the current gear of the valve body according to the relative angle value and the angle range of the calibration initial angle value in the preset deviation. The gear shifting device is characterized by further comprising a display module, wherein the display module is electrically connected with the controller and used for displaying the current gear of the valve body.
The relative angle may have a deviation within an allowable range. In this embodiment, the relative angle has a deviation of plus or minus 5 degrees. Namely, when the valve body gear is calculated, the relative angle value is greater than or equal to 355 degrees and less than or equal to 360 degrees, the valve body gear is the first gear; when the relative angle value is more than or equal to 25 degrees and less than or equal to 35 degrees, the second gear is selected; when the relative angle value is greater than or equal to 55 degrees and less than or equal to 65 degrees, the gear is three; when the relative angle value is greater than or equal to 85 degrees and less than or equal to 95 degrees, the gear is four; when the relative angle value is more than or equal to 115 degrees and less than or equal to 125 degrees, the gear is fifth gear; when the relative angle value is more than or equal to 145 degrees and less than or equal to 155 degrees, the gear is six; when the relative angle value is greater than or equal to 175 degrees and less than or equal to 185 degrees, the gear is seven.
If the valve body is calibrated before leaving the factory, the first gear is used as a set gear, and the initial calibration angle value is 30 degrees. The valve body is rotated to 100 degrees during the use process of a user, namely the absolute angle value is 100 degrees. And the absolute angle value is greater than the calibration initial angle value, so that the initial relative angle value is calculated to be 100-30 degrees to 70 degrees, the relative angle value is compared with the standard gear distribution, and the 70 degrees fall between the second gear and the third gear, so that the fact that the current output firepower is the second gear can be known.
If the valve body is calibrated before leaving the factory, the first gear is used as a set gear, and the initial calibration angle value is 100 degrees. When the valve body is rotated to 30 degrees in the using process of a user, namely the absolute angle value is 30 degrees, the absolute angle value is smaller than the calibration initial angle value, so that the initial relative angle value is calculated to be 30+ 360-100-290 degrees, the initial relative angle value falls between an OFF gear and a first gear, and no firepower is obtained currently.
The above preferred embodiments should be considered as examples of the embodiments of the present application, and technical deductions, substitutions, improvements and the like similar to, similar to or based on the embodiments of the present application should be considered as the protection scope of the present patent.
