In the following, movement, the effect to the washing machine constituted as described above are illustrated.In washing operating, scavenger Sequence is following process: into outer groove 1, supply is dissolved with the washing water of detergent, beat washing by the rotation of sink 4 on one side The dirt of washings 5 is washed off on one side.Rinsing process is carried out after cleaning process.In the rinsing process, it such as carries out in first Between dehydration procedure, the first rinsing process, the second intermediate dehydration procedure, the second rinsing process.Then, dehydration procedure is finally executed.

Firstly, user opens the door 11 that the front surface of shell 2 is arranged in, washings is put into from opening portion 6 to sink 4 5.Then, the power switch (not shown) that the operation display part 25 on front surface top of shell 2 is set is connected, operation starting is opened (not shown) is closed to start to carry out washing operating.

Due to the beginning of washing operating, control unit 21 most starts with the detection of cloth amount test section 22 and is put to sink 4 The amount of interior washings 5.According to the amount of torque or motor 10 applied to motor 10 when rotating with making 4 low speed of sink Current value etc. detects the amount of washings 5.

Control unit 21 and the amount of the washings 5 detected correspondingly set each work of cleaning process, rinsing process, dehydration procedure The time of sequence and the amount of washing water.Correspondingly, make that correspondingly preset detergent amount is shown in behaviour with the amount of washings 5 Make display unit 25.User extracts detergent throw-in part 15a out from detergent box 15, and what is shown according to operation display part 25 washes The target for washing dosage has been put into after detergent, moves detergent throw-in part 15a into detergent box 15.

Feed water valve 14 is opened when detergent investment is completed in the estimation of control unit 21.When opening feed water valve 14, washing Water flows into detergent box 15 from feed water inlet 13, as indicated by arrow B to outer groove 1 while dissolving input detergent It supplies water.The washing water that bottom in outer groove 1 is accumulated flows into sink 4 from the aperture 9 for being formed in sink 4.Water consumption detection Detect the washing water accumulated in outer groove 1 in portion 23.When being supplied with and the amount of washings 5 correspondingly preset specified amount When washing water, control unit 21 closes feed water valve 14.

When supply water complete when, control unit 21 drive motor 10 rotates sink 4.When sink 4 is revolved When turning, the washings 5 in sink 4 is lifted and is fallen from above towards direction of rotation by protruding body 8, to wash to being trapped in The washings 5 for washing the bottom surface of slot 4 or the bottom of sink 4 beat washing.In this way, the chemistry generated by detergent is being utilized Beat washing using the mechanical force while power.The revolving speed that washings 5 is beaten the sink 4 washed is, for example, 45rpm, every regulation Time is inverted to carry out forward and reverse rotation driving.

When carrying out the cleaning process of stipulated time, control unit 21 opens drain valve 18 by the washing water in outer groove 1 It is discharged to outside machine.After the completion of draining, become rinsing process, the first rinsing process is carried out after the first intermediate dehydration procedure. In the same manner as cleaning process, the washing water of specified amount is also supplied into outer groove 1 in the rinsing process, rotates sink 4 To carry out the rinsing of washings 5.

In the dehydration procedure finally carried out, drain valve 18 is being opened come after going out the washing water in outer groove 1 to machine outlet, Rotate the sink for being put into washings 54 at high speed by motor 10, to be dehydrated to washings.Work as dehydration procedure When completion, control unit 21 terminates washing operating.

Then, the effect of the purification and washing water in centrifuge separation portion 20 is illustrated.

In cleaning process, washing water includes the various foreign matters such as fouling material.For example, fouling material includes such as sandstone, fibre Dirt of the specific gravity like that such as bits, hair, cutin dirt than water weight is tieed up, although and as using sebum as rouge ingredient of representative etc. It is lighter than water but as broken the end of a thread etc. specific gravity can be attached to than the fouling material etc. on the dirt of water weight.

In cleaning process, control unit 21 drives rotating cylinder motor 20c so that washing in outer groove 1 comprising fouling material Water is washed to be recycled to centrifuge separation portion 20.When driving rotating cylinder motor 20c, rotating cylinder 20b and pump blade 20k are revolved Turn, by the pumping action generated by pump blade 20k, the washing water in outer groove 1 flows into swirling flow generating unit 20h through 19a by water. The washing of swirling flow generating unit 20h is flowed into from the water route 19a for being connected to connection in a manner of the side for being biased to swirling flow generating unit 20h Water is applied convolution ingredient and flows into rotating cylinder 20b from washing water inlet 20e.Rotating cylinder 20b passes through rotating cylinder motor 20c And it is rotated.Therefore, be directed to the washing water in rotating cylinder 20b becomes the swirling flow of high speed in rotating cylinder 20b.

Washing water is flowing out after washing water inlet 20e importing by rotating cylinder 20b, and from washing water out 20f.This When, the strong centrifugal force specific gravity that makes washing water be included that is generated by the swirling flow of high speed than washing water weight foreign matter towards rotating cylinder The inner peripheral surface 20d of 20b.In this way, the distinctive fouling material of washings that can included by washing water is separated and is removed.

On the other hand, full of in rotating cylinder 20b compared with the recycle stream near the rotary shaft 20g by rotating cylinder 20b The washing water of position in the outer part and compared with the inner peripheral surface 20d of rotating cylinder 20b in the inner part, in addition to occupying rotation by recycle stream Other than the washing water inlet 20e and washing water out 20f of cylinder 20b, the inner peripheral surface of rotating cylinder 20b is also partially toward by recycle stream 20d acts on strong centrifugal force.Thus, it is isolated by centrifugal force from washing water and the dirt of the inner peripheral surface 20d towards rotating cylinder 20b Substance will not be attracted by the recycle stream by rotating cylinder 20b to be returned.

In addition, washing water is fromed bottom to top while circling round to be passed through in the rotating cylinder 20b in centrifuge separation portion 20.At this point, Bubble in the bubble generated in washing water by detergent and water route 19 enters sometimes in rotating cylinder 20b.Even if at this In the case of kind, firstly, the central part that the bubble lighter than water flows to rotating cylinder 20b also with convolution is concentrated, also, it is intended on upwards The flowing of floating effect and washing water from bottom to top interacts, so that the bubble lighter than water is easily from washing water out 20f It is discharged to outside rotating cylinder 20b.The rotation that thereby, it is possible to prevent from generating in rotating cylinder 20b due to the bubble residence lighter than water The imbalance of water and bubble distribution in rotating cylinder 20b can inhibit the variation for making rotating cylinder 20b rotate required torque In minimum limit.In addition, can also prevent the rotation speed change of the rotating cylinder 20b generated by cogging.In addition, due to can The whirling vibration as caused by imbalance is prevented, therefore even if reducing the interval of shell 20a and rotating cylinder 20b, can also be prevented outer The contact of shell 20a and rotating cylinder 20b can larger constitute rotating cylinder 20b.Also, it eliminates since the bubble lighter than water is stagnant Stay in the movement disorder in the rotating cylinder 20b generated in rotating cylinder 20b.It is temporary because of the disorder of flowing thereby, it is possible to prevent It is separated and the foreign matter kept returns in washing water.

The washing water that fouling material is separated in rotating cylinder 20b is flowed out from washing water out 20f to pump chamber 20i.By The pumping action that pump blade 20k is generated makes the washing water for flowing into pump chamber 20i flow into outer groove 1 by water route 19b.Washing in outer groove 1 The pumping function that water has by centrifuge separation portion 20 is recycling between centrifuge separation portion 20 in outer groove 1 through by water 19, To carry out the purification of washing water.Thereby, it is possible to the fouling materials prevented separation out to be again attached to washings 5, make washing machine Cleaning strength improves.

The foreign matter for being collected into inner peripheral surface 20d is flowed in water route 19 to the direction opposite with when sending water in draining Washing water flowing, be discharged via the drain valve 18 being opened to outside machine.The washing water for being set as to be cleaned is not needed as a result, The structure that is discarded in centrifuge separation of a part.

In addition, being also able to carry out the separation for the foreign matter that washing water is included in the rinsing process other than cleaning process. Make to wash out from washings 5 to the foreign matter of washing water in the rinsing process by centrifuge separation portion 20 and separate, thus, it is possible to improve drift Wash effect.In the rinsing process, zeolite of the specific gravity in the cleaning adjuvant that detergent is included than water weight can also be removed (zeolite), improve rinsing performance.
