Abstract
The utility model provides a washing machine inner bucket dehydration rotating speed detection apparatus comprising an outer bucket and an inner bucket of a washing machine, wherein an inner wall of the outer bucket is provided with a Hall sensor, an output end of the Hall sensor is electrically connected with an input end of a microprocessor on a washing machine control panel, an outer wall of the inner bucket is provided with at least a permanent magnet body, and the permanent magnet body and the Hall sensor are on the same horizontal face. When the inner bucket is rotating without stop, a MCU on the washing machine control panel obtains a series of high and low electrical level pulse incoming signals, and actual data of washing machine inner bucket rotating speed can be obtained after the high and low electrical level pulse incoming signals are processed by the MCU. The washing machine inner bucket dehydration rotating speed detection apparatus is characterized by simple structure, small number of investment devices, and good detection effects.
Description
Technical field
The utility model relates to washing machine manufacturing technology field, is specifically related to a kind of pick-up unit of common inner barrel of wave wheel washing machine dehydrating speed.
Background technology
Washing machine is one of indispensable household electrical appliance during people live, and washing machine is cleaned the cleaning that clothes will lean on washing agent on the one hand, in the time of on the other hand exactly will be by dehydration the washings that contain booty be broken away from clothes and comes, thereby reach the purpose of cleaning clothes.Be that bucket is made high speed rotating in it during laundry machine dehydration, produce bigger centrifugal force, moisture is separated with clothing, moisture content aperture by dehydration barrel under action of centrifugal force throw away logical outside outflow, thereby reach the purpose of dehydration.
Rotary drum washing machine is vertical spin dryer, and centrifugal dehydrating speed is generally 500 rev/mins-1500 rev/mins, relies on action of centrifugal force the water in the clothing can be got rid of.Acceleration=0.011N2 R (N represents the per minute rotating speed) during according to dehydration comes theoretical calculation, promotes the rotating speed of washing machine inner tub dehydration, can promote the laundry performance of washing machine to a certain extent.How the laundry performance of washing machine is decided by bucket dehydrating speed in it on the one hand thus.
At present, the common rotary drum washing machine of the non-frequency on the market does not substantially all have the pick-up unit of dehydrating speed, and whether the rotating speed when being unable to find out the washing machine inner tub dehydration when user uses satisfies the requirement of washing most clothes.
The utility model content
In order to solve above-mentioned deficiency, the utility model provides a kind of pick-up unit of common inner barrel of wave wheel washing machine dehydrating speed, reaches the purpose of bucket dehydrating speed in the reflection intuitively.
For achieving the above object, the utility model has adopted following technical scheme:
A kind of pick-up unit of washing machine inner tub dehydrating speed comprises the outer bucket and interior bucket of washing machine, and the outer wall of described outer bucket is provided with Hall element, and the output terminal of described Hall element is electrically connected with microprocessor input end on the washing machine control panel; The outer wall of bucket is provided with at least one permanent magnet in described, and described permanent magnet and Hall element are on same surface level.
Described permanent magnet has three, and their annulars are arranged on the outer wall of interior bucket equally spacedly.
Described Hall element is full polarity Hall element.
Full polarity Hall element is called full polarity switch again, is a kind ofly all to work the latch-type switch of digital quantity output under strong southern magnetic field and strong northern magnetic field.Can not consider that the polarity of magnet installs, one has enough ferromagnetic homopolar magnet and just can make the work of full polarity Hall element.After the full polarity Hall element conducting, will keep conducting state always, be removed, just recover the state that turn-offs up to magnetic field.Device latchs the state after changing, and keeps turn-offing always, arrives again up to a new enough strong magnetic field.
Pick-up unit of the present utility model be respectively Hall element is installed on the outer wall of outer bucket of washing machine, on the outer wall of interior bucket that permanent magnet is installed in washing machine, one that Hall element is electrically connected to microprocessor (MCU) in the computer control panel of washing machine interrupts on amount device port or the I/O port again.When washing machine inner tub rotated, permanent magnet was near Hall element, made the Hall element conducting, and the MCU input signal is set to low level after the conducting; And be rotated further when interior bucket, permanent magnet is during away from Hall element, not conducting of Hall element, this moment MCU input signal by on pull into high level, make its conducting up to next permanent magnet near Hall element, produce one group of low level signal again.So circulation, interior bucket is when not stall is moving, and the input signal that MCU obtains is exactly a series of high and low level pulse, handles the real data of the interior bucket rotating speed that just can obtain washing machine by MCU.
So that this device has is simple in structure, used device is few, detects effective characteristics.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is a vertical view of the present utility model;
Fig. 2 is the C-C cut-open view among Fig. 1;
Fig. 3 is circuit theory diagrams of the present utility model.
Among the figure: the outer bucket of 1-, bucket in the 2-, 3-permanent magnet, the full polarity Hall element of 4-.
Embodiment
As shown in Figure 1 and Figure 2, a kind of pick-up unit of washing machine inner tub dehydrating speed, the outer bucket 1 and interior bucket 2 that comprise washing machine, the outer wall of described outer bucket 1 is provided with full polarity Hall element 4, and the output terminal of described full polarity Hall element 4 is electrically connected with microprocessor input end on the washing machine control panel; Annular is furnished with three permanent magnets 3 equally spacedly on the outer wall of described interior bucket 2, and described permanent magnet 3 and full polarity Hall element 4 are on same surface level.
As shown in Figure 3, the detection principle of this pick-up unit is: interrupt on amount device port or the I/O port because full polarity Hall element is connected electrically in of microprocessor (MCU) in the computer control panel of washing machine.When washing machine inner tub rotated, permanent magnet was near Hall element, made the Hall element conducting, and the MCU input signal is set to low level after the conducting; And be rotated further when interior bucket, permanent magnet is during away from Hall element, not conducting of Hall element, this moment MCU input signal by on pull into high level, make its conducting up to next permanent magnet near Hall element, produce one group of low level signal again.So circulation, interior bucket is when not stall is moving, and the input signal that MCU obtains is exactly a series of high and low level pulse, handles the real data of the interior bucket rotating speed that just can obtain washing machine by MCU.
Above embodiment is not limited only to protection domain of the present utility model, all make amendment based on basic thought of the present utility model or change all belong to protection domain of the present utility model.
