Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Gear code switch structure chart of the present utility model as shown in Figure 2, include guidance panel 3 and be installed in the knob assembly 1 of guidance panel 3 one sides, wherein knob assembly 1 includes knob lid 12 and is inlaid on the knob lid 12 and rotates with the knob lid, thereby the magnet 13 in the magnetic field that changes, and the opposite side of guidance panel 3 is equiped with shift inductor 2, and shift inductor 2 comprises circuit board 23 and is contained in some on the circuit board and produces conducting along with the rotation of magnet 13 successively one by one and disconnect action, to regulate the Hall switch 22 of household electrical appliance firepower size and identification firepower gear.
For ease of installing, also be fixed with positioning element 14 on the above-mentioned knob lid 12, be equiped with first magnet 11 on the positioning element 14, be equiped with on the circuit board 23 and can produce the power that attracts each other to realize second magnet 21 of location with first magnet 11, the position of first magnet 11 is corresponding with the position of second magnet 21, and first magnet 11 end relative with second magnet 21 magnetic pole is different each other.
In the present embodiment, above-mentioned Hall switch 22 is provided with n, n＞=2, and it is evenly distributed on the same circumference.
In addition, for reaching result of use preferably, the diameter of the periphery at above-mentioned magnet 13 places that are embedded in 12 li of swivelling covers is identical with the diameter of the periphery at Hall switch 22 places.
In the present embodiment, above-mentioned positioning element 14 is provided with the rotating shaft 141 that can be installed in the inner set shrinkage pools 121 of swivelling cover 12, and cooperating between rotating shaft 141 and the shrinkage pool 121 is matched in clearance.
Being provided with 10 with Hall switch 22 below is that example further specifies:
The guidance panel 3 here is the crystallite panel, and guidance panel 3 belows are shift inductors 2, is the center of circle with circuit board 23 centers, and radius is to be uniform-distribution with 10 Hall switch 22 on the circumference of 20mm, is numbered: S1, S2, S3,,,,, S10.The center position of circuit board 23 has second magnet 21, is the N utmost point up.
The top of guidance panel 3 is knob assemblies 1, and positioning element 14 centers are embedded with first magnet 11, are the S utmost point down, be used for attracting each other with second magnet 21, thus the fixation of playing.
Positioning element 14 is provided with a rotating shaft 141, and it is the 360 ° of rotations in center with this rotating shaft afterwards that knob lid 12 is enclosed within the rotating shaft by its inner shrinkage pool 121.Axle center with rotating shaft 141 is the center of circle, and radius is that the knob of 20mm covers 12 circumference and is provided with magnet 13, and magnetizing direction is a vertical direction.
Operation principle of the present utility model is: the user rotates the knob lid 12 that is installed on the positioning element 14 by hand, and magnet 13 is also followed together and rotated, thus the magnetic field that changes.Be fixed on 10 Hall switch 22 on the circuit board 23 and be in the variation that detects magnetic field intensity in the magnetic field of variation, correspondingly Hall switch S1, S2, S3,,,,, S10 will produce the action of conducting, disconnection successively one by one.By Hall switch S1, S2, S3,,,,, conducting between the S10 and the sequencing of disconnection regulate firepower size and identification firepower gear.
This shows and since magnet 13 can 10 Hall switch S1, S2, S3,,,,, process successively above the S10, thereby so the Hall switch changes of magnetic field that can sense magnet 13 export corresponding level and change.Such as, when magnet 13 rotates to Hall switch S1 when top, Hall switch S1 conducting output high level, other Hall switch S2, S3, S4,,,, the S10 output low level; When magnet 13 leaves S1 top and arrives the S2 top, Hall switch S2 conducting output high level, other Hall switch S1, S3, S4,,,, the S10 output low level, the rest may be inferred goes down.
When rotating counterclockwise knob and cover 12, the Hall switch 22 on the circuit board 23 is by the order of S1 → S2 → S3 → S4 → S5 → S6 → S7 → S8 → S9 → S10 → S1 circulate successively conducting or disconnection.Oscillogram as shown in Figure 5.
When clockwise rotating knob when covering 12, the Hall switch 22 on the circuit board 23 is by the order of S10 → S9 → S8 → S7 → S6 → S5 → S4 → S3 → S2 → S1 → S10 circulate successively conducting or disconnection.Oscillogram as shown in Figure 5.
When magnet 13 rotate in place between S1 and S2, S2 and S3, S3 and S4, S4 and S5, S5 and S6, S6 and S7, S7 and S8, S8 and S9, S9 and S10, S10 and S1, each Hall switch S1, S2, S3,,,, S10 disconnects output low level.
Utilize above-mentioned this rule just can judge the residing firepower gear of electromagnetic oven.
