Abstract

The present invention discloses a method for controlling unbalance of a washing machine. A water flow raised by a centrifugal force sprays in an inner tank again through an outer cylinder cover and rotates with a high speed in the inner tank along the same direction. When the centrifugal permeating washing or the rinse is carried out, the stage of the unbalance value of a washing tank can be sensed. When the sensed unbalance value of the washing tank is more than a set value, washings in the inner tank can be distributed uniformly to execute a rinsing stroke. When the sensed unbalance value of the washing tank is smaller than the set value, a water-draining stroke or a dewatering stroke is executed after the centrifugal permeating washing or the rinse is finished. The method for controlling unbalance of the washing machine provided by the present invention has the following effects: in the process of the washing stroke and the rinsing stroke, the unbalance condition of the washing tank can be sensed during the finally centrifugal permeating washing and rinse. The further water supply driving during executing the rinsing stroke can be omitted. Therefore, not only the washing time is shortened, but also the washing water consumption is saved.

Description

The unbalance of washing machine control method

Technical field

The invention relates to washing machine, particularly be the unbalance of washing machine control method.

Background technology

Fig. 1 is the cut-away view of general erect type washing machine.As shown in Figure 1, the driving vertical type washing machine of inside groove has following structure: casing 50 is shells of washing machine; Sink 60 is to be made of water jacket 61 and inside groove 65, carries out cleaning of washings in sink 60, and sink 60 is arranged on the inside of casing 50; Be provided with and can make sink 60 hang over four hook parts 55 on the casing 50, hook part 55 is carried out the air disk performances; Drive motors 57 is arranged on the bottom of sink 60, and drive motors 57 drives the rotation of inside groove 65.

In order to achieve the above object, the present invention implements by following scheme, by the current of centrifugal force rising, again spray into to the inside of inside groove through outer bung, rotate at a high speed to a direction at inside groove, carry out centrifugal when seeing through washing and rinsing, stage that can perception sink unbalance amount; In the unbalance amount of perception sink when setting value is above, in order to make the washings in the inside groove can access even distribution execution rinsing stroke, if the unbalance amount of the sink of perception setting value finish when following centrifugal see through washing or rinsing after, carry out draining or the stroke that dewaters.

In the unbalance amount of perception sink when setting value is above, by inside groove within a certain period of time carry out left rotation and right rotation repeatedly, carry out the rinsing stroke.

After the rinsing stroke finishes, carry out centrifugal see through washing or rinsing again.

The unbalance control method of washing machine provided by the invention can be brought following effect.

In washing and rinsing stroke, can be last centrifugal when seeing through washing (rinsing), the imbalance state of perception sink, make when carrying out the rinsing stroke, can save supplies water again drives, thus not only shortened wash time, but also the use amount that can save washings.

The specific embodiment

The present invention is described in detail below in conjunction with the drawings and specific embodiments.Fig. 3 is the cut-away view of tilt washer of the present invention.As shown in Figure 3, the washing machine that sink tilts has following structure: being arranged on casing 50 inside for the vertical direction of gravity effect obliquely with specific angle O has sink 60, sink 60 is to be made of water jacket 61 and inside groove 65, carries out cleaning of washings in sink 60; A plurality of hook parts 55 can make sink 60 hang over obliquely on the casing 50; Drive motors 57 is arranged on the downside of sink 60, and drive motors 57 drives inside groove 65 rotations.

The water jacket 61 of sink 60 is round barrel shapes, by hook part 55 water jacket 61 of heeling condition is hung in the casing 50, stores washings in water jacket 61; Inside groove 65 can be arranged in the water jacket 61 rotatably, carries out cleaning of washings in inside groove 65.

Particularly, the top of water jacket 61 is provided with the outer bung 70 of disk ring-type, the current that the centrifugal force that rotation by inside groove 65 produces rises along water jacket 61 walls can make current again in waterfall water is fallen inside groove 65 through outer bung 70, carry out centrifugal see through washing or rinsing.Washing machine washs or during the rinsing stroke in heeling condition, drive by drive motors 57, directly make cleaning of inside groove 65 rotations carrying out washings, after washing or the end of rinsing stroke, carry out draining or dehydration driving repeatedly, after last dehydration running finished, the clean driving of washings finished.

Fig. 4 is the precedence diagram of the unbalance control method of washing machine of the present invention, Fig. 5 is the chart of sink rotary speed in washing of the present invention and the rinse cycle, be exactly agitator treating or the revolutions per minute speed perception chart that sees through the inside groove of washing, Fig. 6 is Fig. 5 " A " part details drawing, points out out revolutions per minute speed perception chart when seeing through washing.

After the water supply of tilt washer is finished, by the rotation that hockets about inside groove 65, carry out the agitator treating of washing, the current that rise by centrifugal force are carried out centrifugal seeing through and are washed through the ejection of outer bung 70.

Agitator treating is, by the left and right sides positive rotation and the contrary rotation of inside groove 65, makes generation frictional force between the wall of washings and inside groove 65 and washings and the washings clean the washing methods of washings.

Centrifugally see through washing and be, inside groove 65 rotates with certain speed continuously to a direction, can produce centrifugal force in it, along the current that rise between inside groove 65 and the water jacket 61, in inside groove 65, spray into the washing methods of cleaning washings again by centrifugal force through outer bung 70.

As mentioned above, before draining that enters washing stroke and dehydration stroke, agitator treating and centrifugally see through washing and hocket, last centrifugal seeing through in the washing process, when inside groove 65 rotates at a high speed to a direction, unbalance amount that can perception sink 60.

Sense of imbalance perception method to sink 60 has two kinds.A kind of is identical with common washing machine, the sensor senses sink 60 by being arranged on water jacket 61 outsides unbalance; Another kind is according to the perception to the actual rotary speed of drive motors 57, by with the voltage-contrast of confirming, whether sink 60 is measured in the variation of actual rotary speed unbalance, revolutions per minute speed perception method perception sink 60 unbalance.

Particularly, owing to sink 60 is provided with obliquely with special angle,, has improved to unbalance ability to see things in their true light for comparing with the ability to see things in their true light that straight power is provided with sink because of the unbalance ability to see things in their true light of the loading of washings, so in relative low speed rotation, also can easily perceive the unbalance amount of washings.

In addition because the proportionate relationship of shock momentum when possessing the unbalance perception amount of measuring before washings in the sink 60 are discharged from fully and driving with dehydration, so can be before discharging washings the discharge rate of the unbalance back control of perception washings.

By cognitive method, the unbalance amount that perceives sink 60 when the following situation of setting value, finish washing stroke after, can carry out draining or the stroke that dewaters.

If the unbalance amount that perceives sink 60 can access even distribution execution rinsing stroke in order to make the washings in the inside groove 65 when the above situation of setting value.

That is to say only in sink 60, have under the state of washings, just can carry out the centrifugal washing that sees through, so, can carry out the rinsing stroke by inside groove 65 left rotation and right rotation repeatedly within a certain period of time perceiving when unbalance.

During through the end of said method rinsing stroke, re-execute the centrifugal washing while that sees through, the unbalance of groove 60 washed in perception, and be at this moment centrifugal through after the washing if the unbalance amount of the sink of perception 60 when setting value is following, is finished, and finishes washing stroke.

Though top is that the center is illustrated with the washing stroke, the rinsing stroke also is same.

As mentioned above, after washing or rinsing stroke finished, the open row penstock carried out the draining stroke, rotated the stroke that dewaters by the high speed of inside groove afterwards.
