In above-described embodiment, since drip ring 220 is connected to the bucket wall 211 of the keg 210, increase in keg 210 Clothing and water limitation height, and the osculum 223 on drip ring 220 is then conducive to the discharge of water, in 210 low speed of keg When rotation, the smaller internal diameter in 220 middle part of drip ring can avoid water from throwing away, and avoid causing water resource waste, in 210 high speed of keg When rotation, drip ring 220 since the internal diameter at middle part is smaller, and the bucket wall 211 of drip ring 220 and keg 210 connect into it is higher Highly, clothing can be effectively prevent to be thrown out of, and water can then be discharged along osculum 223, effectively increase drainage efficiency, in turn So that the washing of keg 210 and dehydrating effect are more preferably.

For example, the cross section of osculum 223 is circle, for example, the inwardly protruding setting in the Drainage Division 222 has hollow-core construction Columned drainage column, osculum 223 is offered in the middle part of the drainage column, for example, as shown in figure 4, the axial direction of the osculum 223 It is parallel to the axial direction of the ring body 221, in the present embodiment, ring body 221 is identical as the axial direction of keg 210, and is arranged concentrically, then should The axial direction of osculum 223 is parallel with the axial direction of keg 210, and when 210 high-speed rotation of keg, water is under the action of the centrifugal along bucket wall 211 move upwards, since the axial direction of osculum 223 is identical as the direction of bucket wall 211, so that water can be along osculum 223 quickly discharges, and then effectively increase drainage efficiency.

In order to avoid clothing is thrown out of, the ring body 221 in the present embodiment is from both ends to medial recess, i.e., ring body 221 is interior Diameter is reduced from both ends to middle part so that the internal diameter at middle part is smaller, is conducive to carry out blocking limitation to clothing, for example, please referring to figure 4, ring body 221 has C-shaped section or the section similar to C-shaped；For example, the middle part of the ring body is the centre position of C-shaped, The first end and the second end are the end positions of C-shaped；The ring body 221 forms arc surface from both ends to medial recess Outer surface, for example, as shown in Figure 3 and Figure 4, the ring body 221 has an arc section, i.e. the outer surface of the ring body 221 Section is arc-shaped, is flowed along the inner surface of the ring body 221 in this way, being conducive to water, and since the ring body 221 is far from barrel wall The internal diameter of 211 one end is larger, is conducive to clothing and is put into keg 210 or is taken out from keg 210.

In order to enable the water in keg 210 can efficiently be discharged, it is in one embodiment, described incorporated by reference to Fig. 3 and Fig. 4 The internal diameter of Drainage Division 222 is greater than or equal to the internal diameter of the first end 228 of the ring body 221.It is noted that the draining Hole 223 is opened in along the axial direction of Drainage Division 222 on the Drainage Division 222, then the drainage direction of the osculum 223 is along Drainage Division The axial discharge of 222 axial direction i.e. ring body 221, at this point, the internal diameter due to Drainage Division 222 is more than 221 first end 228 of ring body Internal diameter, in this way, each osculum 223 then be located at ring body 221 first end 228 periphery, that is, the circle of each osculum 223 Circular diameter where the heart is more than the internal diameter of 221 first end 228 of ring body, then the circle where the osculum 223 is located at ring body The outside of 221 first ends 228, in this way, when osculum 223 drains, the water of discharge will be discharged by the outside of ring body 221, draining The water that hole 223 is discharged will not be stopped by ring body 221, so that the water of keg 210 can efficiently be arranged by osculum 223 Go out.

In order to improve the leakproofness between drip ring 220 and bucket wall 211, avoid water between drip ring 220 and bucket wall 211 Discharge, in one embodiment, as shown in Figures 2 and 3, small tub assembly 200 further includes sealing ring 240, the Drainage Division 222 It is set on outer circumference surface there are one the annular groove 224 extended along 222 circumferencial direction of the Drainage Division, the sealing ring 240 is arranged In the annular groove 224, and the sealing ring 240 is abutted with the bucket wall 211, i.e., the sealing ring 240 is sheathed on institute Periphery of the ring body 221 close to the first end 228 is stated, for example, the inside of the sealing ring 240 is connected to the ring body 221 First end 228, the outside of the sealing ring 240 is used to abut the bucket wall 211 of keg 210, for example, the sealing ring 240 supports It is connected between the first end 228 of the ring body 221 and the bucket wall 211 of the keg 210, for example, the sealing ring 240 is rubber Circle, the sealing ring 240 of rubber material have favorable elasticity, enable to drip ring 220 can fit closely in bucket wall 211 On, so that the leakproofness between drip ring 220 and bucket wall 211 is more preferably.

In order to fix sealing ring 240, in one embodiment, as shown in Figure 3 and Figure 4, the Drainage Division 222 is circumferentially Groove 224 is arranged in surface indentation, and the sealing ring 240 is sheathed in the groove 224, and in the present embodiment, Drainage Division 222 connects In in 221 first end 228 of ring body and being connected on the outside of first end 228 of ring body 221, and the Drainage Division 222 have it is larger Thickness, outer surface is recessed to form groove 224, and the groove 224 is for housing the sealing ring 240, therefore, the sealing ring 240 can be fixed in the groove 224, not easily to fall off.For example, the osculum 223 runs through the upper and lower surface of Drainage Division 222, And outer circumferential surface recess of the groove 224 along Drainage Division 222 is arranged, in this way, the sealing ring 240 in groove 224 is connected to Bucket wall 211, osculum 223 still are able to so that being connected to outside.

In order to further fix the sealing ring 240, for example, circumferential surface of the groove 224 along Drainage Division 222 is arranged, example Such as, which is annular groove 224, for example, the minimum diameter of the annular groove 224 is more than the interior of the sealing ring 240 Diameter, since the sealing ring 240 has elasticity, even if the diameter of the annular groove 224 is more than the internal diameter of the sealing ring 240, The sealing ring 240 still is able to be supportted big and be sleeved in groove 224 by the groove 224, at this point, sealing ring 240 and the formation of groove 224 Interference fit, which is closely affixed under the elastic force effect of itself in groove 224, so that 240 quilt of sealing ring It is tightly secured in groove 224.

It is noted that when sealing ring 240 is placed in groove 224, it is possible to lead to sealing ring 240 and bucket wall 211 contact area reduces, and causes the bad to drip ring 220 and the sealing effect of bucket wall 211 of sealing ring 240, in order to avoid Bad to drip ring 220 and the sealing effect of bucket wall 211, in one embodiment, the depth of the groove 224 is less than described close The thickness of seal 240, for example, the depth of the groove 224 is less than the diameter in the section of the sealing ring 240, in the present embodiment, The diameter in a certain section of section on a diameter of sealing ring 240 in the section of sealing ring 240, rather than sealing ring 240 entirely seals The diameter of closed loop.Specifically, the depth of groove 224 is more than by the thickness of sealing ring 240 in this present embodiment, therefore so that should It is at least partly exposed or be raised in the groove 224 when sealing ring 240 is placed in the groove 224, so that the sealing ring 240 effectively increase with the contact area of bucket wall 211, so that can closely be abutted between sealing ring 240 and bucket wall 211, make Sealing effect that must be between drip ring 220 and bucket wall 211 is more preferably.

In order to which in 210 high-speed rotation of keg, water can efficiently be discharged, and be uniformly discharged from each osculum 223, In one embodiment, as shown in Figure 3 and Figure 4, several osculums 223 are uniformly arranged around the center of circle of the Drainage Division 222, example Such as, the center of circle of circular cross-section of several osculums 223 around the Drainage Division 222 is uniformly arranged, in this way, working as Drainage Division 222 When with 210 high-speed rotation of keg, the water in keg 210 can be discharged along equally distributed osculum 223, so that small Water in bucket 210 can efficiently, equably be discharged so that dehydrating effect is more preferably.

In order to enable the drainage effect of osculum 223 is more preferably, for example, the aperture of the osculum 223 is 1mm~5mm, preferably The aperture on ground, the osculum 223 is 2.5mm~3.5mm, it is preferable that the aperture of the osculum 223 is 3mm, when osculum 223 Aperture it is excessive, keg 210 slowly run washing when, water be easy is flowed out from osculum 223, cause washing effect bad, When the aperture of osculum 223 is too small, and 210 high-speed rotation of keg drains, shipwreck causes to drain to be discharged from osculum 223 Inefficiency, therefore, in the present embodiment, the aperture of osculum 223 is preferably 3mm, on the one hand, enables to keg 210 low When speed rotation, water is not easy to be discharged from osculum 223 so that washing effect more preferably, on the other hand, then makes keg 210 exist When high-speed rotation, drainage efficiency higher.

In order to further avoid the loss of the washings in washing, in one embodiment, as shown in figure 5, the water blocking Back cavity 201 is formed between ring 220 and bucket wall 211, the osculum 223 is connected to the back cavity 201, for example, the gear The bottom of water ring 220 is connect with the interior sidewall surface of the bucket wall 211,220 rest part of the drip ring and the bucket wall 211 Interior sidewall surface is spaced apart so that described a time in a ring is formed between the drip ring 220 and the bucket wall 211 Chamber 201 is flowed, for example, about 223 osculum runs through the Drainage Division 222, the upper end outlet of the osculum 223 is connected to institute Back cavity 201 is stated, the lower end of the osculum 223 is exported towards the bucket bottom 212.

In the present embodiment, the bottom of drip ring 220 can be the first end 228 that Drainage Division 222 can also be drip ring.Example Such as, 220 middle part of the drip ring and bucket wall 211 form back cavity 201 between one end of bung hole 213, for example, the water blocking Ring 220, sealing ring 240 and bucket wall 211 connect, and inside forms back cavity 201.Since osculum 223 is through Drainage Division 222 Upper and lower surface, and outer circumferential surface of the sealing ring 240 along Drainage Division 222 is arranged, in this way, when Drainage Division 222 passes through sealing ring 240 are connected to barrel wall 211, are connected to the back cavity 201 by osculum 223 inside keg 210.

The back cavity 201 is for collecting the water being discharged when keg 210 slowly runs so that the water of discharge is along osculum 223 flow into keg 210.Specifically, when keg 210 is in washing state, keg 210 slowly runs, and portion of washing water is along logical Wall rises to drip ring 220, and is discharged from osculum 223, at this point, by 220 exterior portion of drip ring and logical wall close to port Part composition back cavity 201 will stop and collect this part discharge washings, and make washings returned through osculum 223 It is flow to keg 210, so as to avoid the loss of washings when washing, avoids the waste of washings so that washing effect is more preferably；And In 210 hull-borne of keg, 210 high-speed rotation of keg, water flows out to back cavity 201 through osculum 223, and in high-speed rotation Under centrifugal action, the bucket wall 211 for continuing on 201 part of back cavity rises, until back cavity 201 is thrown away, to realize keg 210 dehydration.

In order to realize preferably washing effect, and make dehydration efficiency higher, for example, referring again to Fig. 5, the draining The distance that portion 222 abuts position to 213 edge of the bung hole of the interior sidewall surface of the bucket wall 211 is 40mm~60mm, for example, Sealing ring 240 and 213 distance L of bung hole is 40mm~60mm, for example, the Drainage Division 222 abuts the inside of the bucket wall 211 The position of wall surface is 50mm with 213 distance L of the bung hole, for example, sealing ring 240 and 213 distance L of bung hole is 50mm, i.e., The height of the back cavity 201 is 50mm, and in other words, the depth of the back cavity 201 is 50mm, in the present embodiment, back cavity 201 Height is sealing ring 240 and 213 distance L of bung hole.It is noted that the height of the back cavity 201 should not be too large, reflux Even if the height of chamber 201 is excessive then so that keg 210 is in high-speed rotation, the water in back cavity 201 is not easy to get rid of from bung hole 213 Go out, and the height of back cavity 201 is also unsuitable too small, the height of back cavity 201 is too small then to make back cavity 201 in the washing condition The washings of collection are also easy to be thrown out of, and the collecting effect of washings is bad when to washing, and washings are easy to be lost in, and cause to wash It is ineffective.Therefore, in the present embodiment, the drip ring 220 is connected to position and the bung hole 213 of the bucket wall 211 Distance L is preferably 50mm, i.e., the depth of the back cavity 201 is 50mm, on the one hand can effectively prevent slowly running in keg 210 When washings loss, avoid the waste of washings, on the other hand, then so that keg 210 in high-speed rotation, water can be fast Bung hole 213 is thrown away fastly.

In order in 210 high-speed rotation of keg so that washings can efficiently be discharged, in one embodiment, described Angle between bucket wall 211 and the bucket bottom 212 is 90 °~100 °, it should be understood that between bucket wall 211 and bucket bottom 212 Angle is the angle of barrel wall 211 and 212 place plane of bucket bottom, it is worth mentioning at this point that, the angle between bucket wall 211 and bucket bottom 212 Bigger, i.e., bucket wall 211 more tends to flat outward, in this way, in 210 high-speed rotation of keg, water is easier in centrifugal action Lower towards an end motion of the bucket wall 211 far from barrel bottom 212, that is, water is easier moves to drip ring 220, in this way, the discharge effect of water Rate is higher, but is unfavorable for washing when keg 210 slowly runs, and is easy to cause flow water more when keg 210 slowly runs, So that washing effect is bad, therefore, the angle between bucket wall 211 and the bucket bottom 212 should not be too large, in the present embodiment, institute It is 90 °~100 ° to state the angle between barrel wall 211 and the bucket bottom 212, for example, between the bucket wall 211 and the bucket bottom 212 Angle be 91 °~93 °, in the present embodiment, the angle between the bucket wall 211 and the bucket bottom 212 is 91 °, in this way, making Water is obtained in 210 high-speed rotation of keg, relatively efficiently drip ring 220 can be risen to along logical wall and be discharged, and due to bucket wall Angle between 211 and the bucket bottom 212 is unlikely to excessive so that in washing, washings not easily run off keg 210, and make The middle part of keg 210 can more be concentrated on by obtaining washings, so that washing effect is more preferably.It should be noted that for general Logical washing machine 10, through manufacturing experimently comparisons repeatedly, using with 91 ° of angles bucket wall 211 and bucket bottom 212 and aperture be 3mm Osculum 223, the two matches, and has taken into account washing effect of the keg 210 when slowly running and keg 210 in high-speed rotation When drainage efficiency, to have preferable laundry effect.

Under washing state, keg 210 slowly runs, and portion of washing water can rise to drip ring 220 along bucket wall 211, And be expelled in back cavity 201 by osculum 223, this portion of washing water is in subsequent washing process, again through osculum 223 It flows into keg 210, avoids the waste of washings so that washing effect is more preferably；Under dewatering state, 210 high speed rotation of keg is small Water in bucket 210 climbs along 91 ° of bucket wall 211 rapidly upwards, enters back cavity 201 by osculum 223, and revolve in high speed It is thrown away from bung hole 213 to keg 210 out of back cavity 201 under the centrifugal action turned, realizes dehydration.Due to keg 210 The integrally connected of barrel and bucket bottom 212 so that keg 210 is isolated from the outside, " draining " and " dehydration " by high speed rotation to Upper " getting rid of " goes out outside keg 210, and into interior bucket 100, the drainage system discharge through interior bucket 100 has effectively prevented keg 210 The cross contamination of inside and outside water.
