Impeller 300 is rotatably disposed in inner cylinder 200, and impeller 300 is limited in inner cylinder 200 above impeller 300 Washing cavities 220 and water containing chamber 230 positioned at the lower section of impeller 300, it can be understood as, the space in inner cylinder 200 is with impeller 300 Boundary is divided into two parts, is washing cavities 220 above impeller 300, and being located at 300 lower section of impeller is water containing chamber 230, i.e., Water containing chamber 230 is limited between the lower surface of impeller 300 and the inner bottom surface of inner cylinder 200.Water containing chamber 230 by chip removal mouth 210 with Spatia 120 is connected to, and impeller 300 is equipped with several fill holes 310 of connection washing cavities 220 and water containing chamber 230, the bottom of impeller 300 Portion is equipped with several draining muscle 320 for protruding into water containing chamber 230.Draining muscle 320 pushes the stream in water containing chamber 230 when impeller 300 rotates Body enters spatia 120 by chip removal mouth 210, and the fluid in washing cavities 220 fills into water containing chamber 230 by fill hole 310.

Wherein, the cross-sectional area (i.e. circulation area) of single fill hole 310 is 10mm²~20mm²。

The chip removal process of washing machine 1 according to an embodiment of the present invention is described below with reference to Fig. 2.

When being washed, impeller 300 rotates washing machine 1, and draining muscle 320 is rotated with impeller 300, in water containing chamber 230 Water is done centrifugal movement by the exclusion for draining muscle 320, is entered in spatia 120 to push water flow by chip removal mouth 210, will Line bits in inner cylinder 200 are emitted between inner cylinder 200 and outer barrel 100 with water flow.In the process, generate in water containing chamber 230 compared with Big negative pressure promotes the water flow in washing cavities 220 to be flowed from fill hole 310 to water containing chamber 230, is subtracted with supplementing in water containing chamber 230 Few water maintains entire water circulation.After impeller 300 stops rotating, into spatia 120 in line bits in water can gradually settle To the bottom of outer barrel 100, in draining, the line bits in spatia 120 are automatically drained out with water flow by discharge outlet 110.

For the side wall of inner cylinder 200 is equipped with the washing machine of permeable hole, after impeller 300 stops rotating, in spatia 120 Water flow can be entered in washing cavities 220 by permeable hole, and since the cross-sectional area of permeable hole is smaller, there is certain filtering line The ability of bits, line bits will not return to washing cavities 220 with water flow, but gradually be precipitated to the bottom of outer barrel 100.

Washing machine 1 according to an embodiment of the present invention that is, in washing, makes line bits pass through chip removal by temporal separation principle Mouth 210 enters spatia 120 by washing cavities 220, and in draining, dehydration, the line bits in spatia 120 are driven using washing water It is discharged from discharge outlet 110, to complete the automatic cleaning of line bits, is promoted in washing cavities 220 in such a way that water flow is squeezed in centrifugation Water flow flow into spatia 120 in flow, significantly increase line consider to be worth doing discharge rate.

Also, the efficiency that whether can be discharged and be discharged is considered to be worth doing since the parameter setting of fill hole 310 is directly related to line, By limiting the cross-sectional area of fill hole on impeller, i.e., the cross-sectional area of single fill hole 310 is 10mm²~20mm², preferably 13mm²~18mm², and the maximum span that can further limit the cross section of fill hole 310 is not more than 6mm.

It on the one hand can make fill hole 310 that there is sufficiently large cross-sectional area as a result, be generated when being rotated in conjunction with impeller 300 Resistance, guarantee fill hole 310 at whole resistance to water-flow the water flow in washing cavities 220 can be enable to can smoothly enter into water containing chamber 230, to guarantee that line bits can smoothly enter into water containing chamber 230；

On the other hand the cross-sectional area that can be avoided fill hole 310 is excessive, prevents remaining coin and button etc. in clothes Foreign matter falls into fill hole 310, these foreign matters is avoided to enter water containing chamber 230 or spatia 120, to eliminate the fiber crops for being difficult to take out It is tired.

It is experimentally confirmed, the corresponding relationship of the cross-sectional area and line bits discharge rate of single fill hole 310 is as follows:

7mm², line bits discharge rate 30%；

10mm², line bits discharge rate 60%；

13mm², line bits discharge rate 69%；

16mm², line bits discharge rate 77%；

19mm², line bits discharge rate 81%.
