Problems solved by technology

[0003] When the pot with the bottom diameter between the large pot and the small pot is placed on the induction cooker, the induction cooker may misjudge, which may cause the induction cooker to adjust the power and heat
That is to say, during the heating process, if the induction cooker is judged to be a small pot, stop heating, and if it is judged to be a large pot when the pot is checked again, it will be heated. When the above process is repeated, it may form a power adjustment phenomenon of heating for a while and not heating for a while. , it is difficult to carry out normal heating, which is not conducive to the use of users
In addition, the method of pulse detection will be affected by the interference of the environment (such as electromagnetic field, working voltage, etc.), resulting in inaccurate detection results

Embodiment approach 1

[0079] Such as Figure 3A As shown, a sensor 306 is set at the center point in the pot heating area 304 on the induction cooker panel 302, and set on the circumference 312 of the first circular area with the center point as the center and the first preset distance as the radius at least one sensor, Figure 3A There are two sensors, namely sensor 308 and sensor 310 . Wherein, the first preset distance may be the critical radius of a standard small pot, such as 30 mm, to determine whether the pot is a small pot.

Embodiment approach 2

[0081] Such as Figure 3B As shown, a sensor 306 is set at the center point in the pot heating area 304 on the induction cooker panel 302, and set on the circumference 312 of the first circular area with the center point as the center and the first preset distance as the radius at least one sensor, Figure 3A There are two sensors, namely sensor 308 and sensor 310, and one sensor 314 is set inside the first circular area. Wherein, the first preset distance may be the critical radius of a standard small pot, such as 30 mm, to determine whether the pot is a small pot.

[0082] Certainly, the number of sensors arranged inside the first circular area may be any number, and the positions may also be set arbitrarily, for example, the sensor 314 may only be arranged inside the first circular area.

Embodiment approach 3

[0084] Such as Figure 3C shown in Figure 3A On the basis of the setting method, at least one sensor is set on the circumference 316 of the second circular area with the center point as the center and the second preset distance as the radius, Figure 3C Only one sensor 318 is provided on the circumference 316 of the second circular area. Wherein, the first preset distance can be the critical radius of a standard small pot, such as 30mm, to determine whether the pot is a small pot, and the second preset distance can be the critical radius of a standard large pot, such as 50mm , to determine whether the pot is a large pot, and whether it is between a large pot and a small pot.

[0085] Of course, in order to judge the size of the pot more accurately, a plurality of sensors can be set at different distances from the center of the pot heating area in the pot heating area, so as to detect the The obtained value judges the size of the pot.

[0086] In addition, the technical so...

Abstract

The invention provides an induction cooker and a method for judging the size of a pan of the induction cooker. The method for judging the size of a pan comprises an obtaining step and a judging step, wherein induction values of multiple sensors for detecting a pan state at different positions in a heating region are obtained when a pan is arranged on a pan heating region of the induction cooker; and according to the induction values of the multiple sensors, the size of the pan is judged. According to the technical scheme, the induction cooker and the method provided by the invention have the advantage that a condition that the size of the pan arranged on the induction cooker is accurately detected is realized, and the accuracy of a judging result on the size of the pan is improved.

Description

technical field [0001] The invention relates to the technical field of induction cooker, in particular to a method for judging the size of a pan used in an induction cooker and an induction cooker. Background technique [0002] At present, the method for judging the size of the pan used in the induction cooker proposed in the related art is mainly by calculating the number of pulses generated by the pan during the pan inspection process, that is, the number of pulses generated by pans of different sizes is different, and the pan is distinguished according to the number of pulses. The size of the bottom dimension. Specifically, when the number of pulses generated by the pot is less than a predetermined value, it is judged as a small pot, and the induction cooker does not heat it; when the number of pulses generated by the pot is greater than another predetermined value, it is judged as a large pot, and the induction cooker Heat it up. [0003] When the pot with the bottom d...
