The device body comprises a gas stove, an induction cooker, an electromagnetic heating pressure cooker, an electromagnetic heating electric cooker, a water heater, a wall-mounted stove and the like, but is not limited to; the adjusting device comprises a fixing part 1 arranged in the electric appliance body and a rotating part 2 which is arranged outside the equipment body and is connected with the fixing part 1 in a rotatable magnetic attraction manner, and the rotating part 2 can be placed outside the equipment body and is magnetically attracted to the fixing part 1 or taken down from the equipment body.

Example two

Referring to fig. 1-3, specifically, a fixed member 1 is provided with Y hall elements 3, Y is greater than or equal to 3 and is an integer, a rotating member 2 is rotatably magnetically attracted and connected to the fixed member 1, X first magnets 4 are uniformly distributed on the rotating member 2 in the circumferential direction, X is greater than or equal to 2 and is an integer, the first magnets 4 can positively correspond to the hall elements and generate sensing signals, an included angle from two adjacent hall elements 3 to the center of a circle is set as W, an included angle from two adjacent first magnets 4 to the center of a circle is set as Z, Y included angles W are not equal to integer multiples of the included angle Z, and the value of at least one included angle W is not equal to the value of the remaining included angles W, when the rotary member 2 rotates, y Hall element 3 just corresponds with first magnet 4 and forms Y induction signal that has the phase difference, and further, adjusting device still includes controller 9, and controller 9 is connected with Y Hall element 3 respectively and is used for detecting the direction of rotation of rotating member 2 according to Y induction signal.

The rotating part 2 is magnetically attracted with the fixing part 1, so that mechanical connection between the rotating part 2 and the fixing part 1 can be avoided, mechanical loss is caused, and the surface structural integrity of the fixing part 1 and the rotating part 2 can be kept. When the rotating member 2 rotates, the rotating member 2 drives the X first magnets 4 to rotate, and the first magnets 4 can be opposite to the Y Hall elements 3 to generate Y induction signals, because the Y included angles W are not equal to the integral multiple of the included angle Z and the value of at least one included angle W is not equal to the value of other included angles W, therefore, when the rotating member 2 rotates, the X first magnets 4 are opposite to the Y induction signals with the phase difference generated by the Y Hall elements 3, during use, the rotating direction of the rotating member 2 can be identified according to the Y induction signals by respectively connecting with the Y Hall elements 3 through the controller 9, the size is adjusted, in addition, the values of all the included angles W can also be unequal, thereby the difficulty of laying the Hall elements 3 is reduced, and the production efficiency is improved. The utility model provides an adjusting device, simple structure, control is simple, accurate.

Referring to fig. 6, in this embodiment, Y hall elements 3 may correspond to two adjacent first magnets 4, so that Y hall elements 3 meeting the angle requirement may be quickly set, and the sequence of the sensing signals of Y hall elements 3 may be accurately known during rotation, so as to facilitate the design of program work by personnel. Of course, in addition to this arrangement, the Y hall elements 3 may be distributed and arranged correspondingly between the intervals of a plurality of sets of two adjacent first magnets 4 (see fig. 4).

In this embodiment, the controller 9 is an editable logic controller capable of controlling the execution elements to perform actions according to computer program execution instructions.

Further, the rotating member 2 is magnetically connected with the fixing member 1, when the rotating member 2 is placed on the fixing member 1, one of the hall elements 3 of the Y hall elements 3 positively corresponds to one of the first magnets 4 of the X first magnets 4 and generates an induction signal, and the induction signal is transmitted to the controller 9. So, can guarantee to place hall element 3 and first magnet 4 quick accurate location when mounting 1 at rotating member 2 for controller 9 can detect out rotating member 2 according to this induced signal very first time and place on mounting 1, improves the user experience effect in the adjusting device use. In the present embodiment, the S-pole of the first magnet 4 is disposed toward the fixing member 1, so that the relative positions of the hall element 3 and the first magnet 4 are uniquely determined when the controller 9 acquires an induction signal. If the N-pole of the first magnet 4 is directed downward, a high level is always generated when the hall element 3 is not provided with a magnet, even if the hall element 3 generates a high level in the positive correspondence with the first magnet 4, the hall element 3 needs to correspond between two adjacent first magnets 4 in order to be able to acquire a low level different from the high level to detect a signal output by the controller 9, and thus, when the distance between two adjacent first magnets 4 is too large, the rotating member 2 needs to be rotated to a proper position when being placed on the fixed member 1, that is, the hall element 3 needs to be located between two adjacent first magnets 4 and is influenced by the reverse magnetic force of the first magnets 4 to the hall element 3 to output a low level, therefore, the signal that the rotating member 2 is placed on the fixed member 1 cannot be detected quickly at the first time, and the purpose of quickly detecting whether the rotating member 2 is placed on the rotating member 2 cannot be achieved.

It should be noted that, in this embodiment, the present invention mainly protects the mechanical structure of the whole adjusting device, and the software control program part related to the controller does not serve as the protection scope of the present invention.

Referring to fig. 4 to 8, in order to explain in further detail the process of the controller 9 recognizing the rotation direction of the rotary member 2, the present embodiment is exemplified by three hall elements 3 and six first magnets 4:

three Hall elements 3 (see figure 4) are arranged on the fixed part 1, when one end of the first magnet 4 facing the fixed part 1 is set to be an N pole, the Hall elements 3 output low levels when not facing the first magnet 4, six first magnets 4 (see figure 6) are uniformly distributed on the rotating part 2, figure 6 is a schematic diagram of correspondingly mapping the Hall elements 3 on the fixed part 1 to the rotating part 2, when the rotating part 2 rotates from a point A to a point B, waveforms output by the three Hall elements 3 of No. 1 to No. 3 are shown in figure 7, because the values of Y included angles W are not equal to integral multiples of an included angle Z and the value of at least one included angle W is not equal to the value of the rest included angles W, the three Hall elements 3 can be ensured to be sequentially facing the first magnet 4 to generate 3 high levels, namely, the Hall element 3 of No. 1 is firstly facing the first magnet 4 to generate high levels, when the rotating member 2 rotates from point B to point a, the waveforms output by the three hall elements 3 are as shown in fig. 8, that is, the hall element 3 No. 3 and the first magnet 4 generate a high level, the hall element 3 No. 2 in the middle is used as a reference, and when the waveform jumping edge of the hall element 3 No. 2 comes, the controller 9 judges the high-low level state of 1 and 3, that is, the forward and reverse rotation of the rotating member 2 can be judged.

It should be noted that the three hall elements 3 may be sequentially and positively corresponding to the same first magnet 4 to generate an induction signal, or the three hall elements 3 may be sequentially and positively corresponding to different first magnets 4 to generate an induction signal, and may be arranged according to actual requirements of the hall elements 3 and the first magnets 4.

When one end of the first magnet 4 facing the fixing part 1 is set to be an S pole, the Hall element 3 outputs a high level all the time when the first magnet 4 is not opposite to the first magnet 4, when the rotating part 2 rotates, the rotating part 2 drives the first magnet 4 to rotate right above the Hall element 3, the Hall element 3 still outputs the high level, after the first magnet 4 leaves the upper part of the Hall element 3 after the rotating part 2 rotates continuously, the Hall element 3 outputs the low level, the controller 9 can judge the forward and reverse rotation of the rotating part 2 according to the same judging method of the N pole setting, and the detection principle is not repeated herein.

The first magnet 4 is described only in the case where the N-pole and the S-pole are set to the stator 1, and the level is generated when the hall element 3 does not correspond to the first magnet 4 when the initial rotor 2 is set in the stator 1. In addition, when the initial rotating member 2 is placed on the fixed member, the hall elements 3 correspond to the first magnets 4, the hall elements 3 can generate waveforms with phase differences in the rotating process of the rotating member 2, and the controller 9 can also temporarily acquire the high and low level states of the two hall elements 3 adjacent to the middle hall element 3 according to the waveform jumping edge of the middle hall element 3, so that the rotating direction of the rotating member 1 can be judged.

Wherein, when the rotating member 2 is placed on the fixed member 1, the controller 9 simultaneously obtains the sensing signals. In this step, one of the hall elements 3 may be aligned with one of the first magnets 4, and at this time, the first magnet 4 should have its S-pole facing the fixing member 1, so that it is ensured that the controller 9 can quickly acquire the sensing signal when the rotating member 2 is placed on the fixing member 1, thereby implementing the positioning function.
