Level；When the second detection zone detects magnet 2, the second Hall element 32 exports high level；When third detection zone detects
When to magnet 2, third Hall element 33 exports high level.
As shown in figure 3, when magnet 2 turns to the regions a with belt pulley 1, the first Hall element 31 output high level, second
Hall element 32 exports low level, and third Hall element 33 exports low level, and Hall subassembly 3 exports low level.
When magnet 2 turns to the regions b with belt pulley 1, the first Hall element 31 exports high level, the second Hall element 32
High level is exported, third Hall element 33 exports low level, and Hall subassembly 3 exports low level.
When magnet 2 turns to the regions c with belt pulley 1, the first Hall element 31 exports low level, the second Hall element 32
High level is exported, third Hall element 33 exports low level, and Hall subassembly 3 exports high level.
When magnet 2 turns to the regions d with belt pulley 1, the first Hall element 31 exports low level, the second Hall element 32
High level is exported, third Hall element 33 exports high level, and Hall subassembly 3 exports low level.
When magnet 2 turns to the regions e with belt pulley 1, the first Hall element 31 exports low level, the second Hall element 32
Low level is exported, third Hall element 33 exports high level, and Hall subassembly 3 exports low level.
When Hall subassembly 3 exports high level, i.e., when magnet 2 turns to position shown in Fig. 2 with belt pulley 1, judge belt
Wheel 1 and inner cylinder rotating are to target location, i.e., the position that inside drum cover is aligned with outer cover.
Further, although not showed that in figure, the washing machine of the utility model further includes controller, which uses
In the output level for acquiring each Hall element, and combine the output level judgement Hall subassembly 3 of each Hall element
Output level.When Hall subassembly 3 exports high level, driving motor is made to stop operating.Or those skilled in the art can also
Processing unit is set on Hall subassembly 3, the output level of three Hall elements is acquired and judges the defeated of Hall subassembly 3
Go out level, the output level of Hall subassembly 3 is then sent to controller.
It should be noted that the first Hall sensor 31, the second Hall sensor 32 and third Hall sensor 33 are examined
What is surveyed is the magnetic field that magnet 2 generates, and the L in attached drawing 2 is intended merely to facilitate the operation principle for illustrating the utility model, and indicate
Length, therefore, those skilled in the art should be interpreted broadly L.
In addition, it will be appreciated to those of skill in the art that the washing machine of the utility model may be omitted with belt pulley, and
Driving motor is arranged between inner cylinder and outer barrel.The driving motor has outer rotor and inner stator, and the outer rotor and inner cylinder are same
Axis is fixedly connected, which is fixedly connected with outer barrel.Further, magnet 2 is arranged on the excircle of outer rotor, by Hall
Component 3 is arranged on the outer barrel that the rotating path with the magnet 2 aligns.
Skilled artisans will appreciate that the three Hoare logic locating and detecting devices of the utility model are in addition to can be by
It applies on above-mentioned top opening barrel washing machine, is also applied on the object of other any twos relative movement, example
Such as, rolling screen door, hoistable platform, lifting machine etc..Illustratively, magnet 2 is arranged onto the free end of the door body of rolling screen door, it will suddenly
In your setting to doorframe of component 3.
In conclusion the signal of the c region detections magnet 2 by the Hall subassembly 3 of the utility model, can accurately sentence
The information in place for determining magnet 2 facilitates user that will throw clothing to belt pulley 1 and inner cylinder accurately position and lock
Enter in inner cylinder, and takes out clothing from inner cylinder.Further, by change the first Hall element 31 and the second Hall element 32 it
Between distance and change the and the distance between Hall element 32 and third Hall element 33, the length of L can be adjusted, Jin Erneng
Enough effective distances of adjustment c region detections magnet 2.Distance L is smaller, the position for the magnet 2 that the second Hall element 32 detects
Information is more accurate.Therefore, the utility model detected by three Hall elements the technical solution of the position signal of magnet 2 with it is existing
The technical solution for detecting the position signal of magnet 2 in technology by Hall element is compared, precision higher, enable inner cylinder by
Accurate lock is in place.
So far, it has been combined preferred embodiment shown in the drawings and describes the technical solution of the utility model, still, this
Field technology personnel are it is easily understood that the scope of protection of the utility model is expressly not limited to these specific implementation modes.
Under the premise of the principles of the present invention, those skilled in the art can make the relevant technologies feature equivalent change
Or replace, the technical solution after these changes or replacement is fallen within the scope of protection of the utility model.
