In a further embodiment, the Drainage Division 222 is connected to the interior sidewall surface of the bucket wall 211 so that drip ring 220 It is fixed in keg 210.

For example, the Drainage Division 222 is arranged on the lower section of the ring body 221, the osculum 223 is multiple, the row Water hole 223 and in a ring arranged for interval are on the Drainage Division 222 near the position of the bucket wall 211.

For example, the radial section of the Drainage Division 222 is annular, for example, the Drainage Division 222 is annular Drainage Division, for example, The Drainage Division 222 is coaxially disposed with the described ring body 221, for example, the inside of the inside of the Drainage Division 222 and the ring body 221 Connection, the inside connection of the inside, the inside of ring body 221 and the keg 210 of the Drainage Division 222, so, clothing can be through the gear Water ring 220 takes out into keg 210 or from keg 210 through drip ring 220.In order to improve the intensity of drip ring 220, for example, The ring body 221 and the integrally connected of the Drainage Division 222, due to ring body 221 and the integrally connected of the Drainage Division 222, effectively carry The intensity of drip ring 220 high, and because the Drainage Division 222 has larger thickness, ring body 221 can be effectively supported, therefore, When with 210 high-speed rotation of keg, the drip ring 220 is not likely to produce deformation.

In above-described embodiment, the bucket wall 211 of the keg 210 is connected to due to drip ring 220, increased 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 the low speed of keg 210 During rotation, the less internal diameter in the middle part of drip ring 220 can avoid water from throwing away, it is to avoid cause water resource waste, in keg 210 at a high speed During rotation, drip ring 220 is smaller due to the internal diameter at middle part, and drip ring 220 and keg 210 bucket wall 211 connect into it is higher Highly, clothing can be effectively prevented to be thrown out of, and water can then be discharged along osculum 223, effectively increase drainage efficiency, and then 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, inwardly protruding setting the in the Drainage Division 222 has hollow-core construction Columned drainage column, the drainage column middle part offer osculum 223, for example, as shown in figure 4, the axial direction of the osculum 223 Parallel to the axial direction of the ring body 221, in the present embodiment, ring body 221 is identical with the axial direction of keg 210, and is arranged concentrically, then should The axial direction of osculum 223 is axially in parallel with keg 210, and when 210 high-speed rotation of keg, water is under the action of the centrifugal along bucket wall 211 motions upwards, because the axial direction of osculum 223 is identical with the direction of bucket wall 211, therefore so that water energy is enough along osculum 223 quick discharges, and then effectively increase drainage efficiency.

In order to avoid clothing is thrown out of, from two ends to medial recess, i.e., ring body 221 is interior for the ring body 221 in the present embodiment Footpath is reduced from two ends to middle part so that the internal diameter at middle part is smaller, is conducive to carrying out stop limitation to clothing, for example, refer 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 second end are the end positions of C-shaped；The ring body 221 forms arc surface from two ends to medial recess Outer surface, for example, as shown in Figure 3 and Figure 4, the ring body 221 has arc section, the i.e. outer surface of the ring body 221 Section is curved, so, is conducive to water to be flowed along the inner surface of the ring body 221, and because the ring body 221 is away from bucket wall The internal diameter of 211 one end is larger, is conducive to clothing to be put into keg 210 or taken out from keg 210.

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

In order to improve the sealing between drip ring 220 and bucket wall 211, it is to avoid water is between drip ring 220 and bucket wall 211 Discharge, in one embodiment, as shown in Figures 2 and 3, small tub assembly 200 also includes sealing ring 240, the Drainage Division 222 Outer circumference surface is provided with an annular groove 224 extended along the circumferencial direction of the Drainage Division 222, and the sealing ring 240 is set In the annular groove 224, and the sealing ring 240 is abutted with the bucket wall 211, i.e., described sealing ring 240 is sheathed on institute Periphery of the ring body 221 near the first end 228 is stated, for example, the inner side 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 is supported 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 quality of rubber materials has favorable elasticity, enable to drip ring 220 can be brought into close contact in bucket wall 211 On, and then cause sealing between drip ring 220 and bucket wall 211 more preferably.

In order to sealing ring 240 is fixed, in one embodiment, as shown in Figure 3 and Figure 4, the Drainage Division 222 is circumferentially Surface indentation sets groove 224, and the sealing ring 240 is sheathed in the groove 224, and in the present embodiment, Drainage Division 222 connects In in the first end 228 of ring body 221 and being connected on the outside of first end 228 of ring body 221, and the Drainage Division 222 have it is larger Thickness, its outer surface is recessed to form groove 224, and the groove 224 is used to house the sealing ring 240, therefore, the sealing ring 240 can be fixed in the groove 224, difficult for drop-off.For example, upper and lower surface of the osculum 223 through Drainage Division 222, And groove 224 is set along the outer circumferential surface depression of Drainage Division 222, so, when the sealing ring 240 in groove 224 is connected to Bucket wall 211, osculum 223 still is able to so that and ft connection.

In order to further fix the sealing ring 240, for example, the groove 224 is set along the circumferential surface of Drainage Division 222, example Such as, the groove 224 is annular groove 224, for example, the minimum diameter of the annular groove 224 is interior more than the sealing ring 240 Footpath, because the sealing ring 240 has elasticity, therefore, even if the internal diameter with diameter greater than the sealing ring 240 of the annular groove 224, The sealing ring 240 still is able to be supportted big and be enclosed within groove 224 by the groove 224, and now, sealing ring 240 is formed with groove 224 Interference fit, the sealing ring 240 is closely affixed in groove 224 under the elastic force effect of itself, and then causes the quilt of sealing ring 240 It is tightly secured in groove 224.

It is noted that when sealing ring 240 is placed in groove 224, it is possible to cause sealing ring 240 and bucket wall 211 contact area reduces, and causes the not good with the sealing effectiveness of bucket wall 211 to drip ring 220 of sealing ring 240, in order to avoid Not good with the sealing effectiveness of bucket wall 211 to drip ring 220, in one embodiment, the depth of the groove 224 is less than described close The thickness of seal 240, for example, diameter of the depth of the groove 224 less than 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, entirely seals rather than sealing ring 240 The diameter of closed loop.Specifically, due to the depth of the thickness more than groove 224 of sealing ring 240 in the present embodiment, therefore so that should Sealing ring 240 is placed in when in the groove 224, at least partly exposes or be raised in the groove 224, and then cause the sealing ring 240 effectively increase with the contact area of bucket wall 211, and then cause closely be abutted between sealing ring 240 and bucket wall 211, make Sealing effectiveness that must be between drip ring 220 and bucket wall 211 is more preferably.

In order in 210 high-speed rotation of keg, water energy is enough efficiently discharged, and is uniformly discharged from each osculum 223, In one embodiment, as shown in Figure 3 and Figure 4, some 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 some osculums 223 around the Drainage Division 222 is uniformly arranged, so, when Drainage Division 222 During with 210 high-speed rotation of keg, the water energy in keg 210 is enough discharged along equally distributed osculum 223, and then is caused small Water energy in bucket 210 enough efficiently, is equably discharged so that dehydrating effect is more preferably.

In order that obtain the drainage effect of osculum 223 more preferably, for example, the aperture of the osculum 223 is 1mm~5mm, preferably Ground, the aperture of 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, the water capacity flows out easily from osculum 223, causes clean result not good, When the aperture of osculum 223 is too small, during 210 high-speed rotation draining of keg, shipwreck is discharged with from osculum 223, causes draining Inefficiency, therefore, in the present embodiment, the aperture of osculum 223 is preferably 3mm, on the one hand, enable to keg 210 low When speed is rotated, water is not easy to be discharged from osculum 223 so that clean result more preferably, on the other hand, then causes that keg 210 exists During high-speed rotation, drainage efficiency is higher.

In order to further avoid the loss of the washings in washing, in one embodiment, as shown in figure 5, the dash Back cavity 201 is formed between ring 220 and bucket wall 211, the osculum 223 is connected with the back cavity 201, for example, the gear The bottom of water ring 220 is connected with the interior sidewall surface of the bucket wall 211, the remainder of the drip ring 220 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 Stream chamber 201, for example, the osculum runs through the Drainage Division 222, the upper end outlet connection institute of the osculum 223 about 223 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 Drainage Division 222 can also be drip ring first end 228.Example Such as, the middle part of the drip ring 220 and bucket wall 211 form back cavity 201 between one end of bung 213, for example, the dash Ring 220, sealing ring 240 and bucket wall 211 are connected, and are internally formed back cavity 201.Because osculum 223 is through Drainage Division 222 Upper and lower surface, and sealing ring 240 is set along the outer circumferential surface of Drainage Division 222, so, when Drainage Division 222 passes through sealing ring 240 are connected to barrel wall 211, and the inside of keg 210 is connected by osculum 223 with the back cavity 201.

The back cavity 201 is used to collect the water 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, now, by the Outboard Sections of drip ring 220 and logical wall near port The back cavity 201 of part composition will stop and collect the washings of this part discharge, and cause washings through osculum 223 times Keg 210 is flow to, so as to avoid the loss of washings during washing, it is to avoid the waste of washings so that clean result is more preferably；And In the hull-borne of keg 210, during 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 the part of back cavity 201 rises, until back cavity 201 is thrown away, so as to realize keg 210 dehydration.

In order to realize preferably clean result, and cause that dewatering efficiency is higher, for example, referring again to Fig. 5, the draining Portion 222 abut the position of the interior sidewall surface of the bucket wall 211 to the distance at the edge of the bung 213 be 40mm~60mm, for example, Sealing ring 240 is 40mm~60mm apart from L with bung 213, for example, the Drainage Division 222 abuts the inner side of the bucket wall 211 The position of wall is 50mm apart from L with the bung 213, for example, sealing ring 240 is 50mm apart from L with bung 213, 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 Sealing ring 240 is highly with bung 213 apart from L.It is noted that the height of the back cavity 201 is unsuitable excessive, backflow Even if the highly excessive of chamber 201 then causes keg 210 in high-speed rotation, the water in back cavity 201 is not easy to be got rid of from bung 213 Go out, and the height of back cavity 201 is also unsuitable too small, the highly too small of back cavity 201 then causes back cavity 201 in the washing condition The washings of collection are also easily thrown out of, and the collecting effect of washings is not good during to washing, and washings are easily lost in, and causes washing Effect on driving birds is not good.Therefore, in the present embodiment, the drip ring 220 is connected to position and the bung 213 of the bucket wall 211 50mm, the i.e. depth of the back cavity 201 are preferably for 50mm apart from L, on the one hand can effectively prevent from slowly running in keg 210 When washings loss, it is to avoid the waste of washings, on the other hand, then cause keg 210 in high-speed rotation, water energy is enough fast Bung 213 is thrown away fastly.

It is in one embodiment, described in order in 210 high-speed rotation of keg so that washings can be discharged efficiently 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 the place plane of bucket bottom 212, it is worth mentioning at this point that, the angle between bucket wall 211 and bucket bottom 212 It is bigger, i.e., bucket wall 211 more tend to outwards it is flat, so, in 210 high-speed rotation of keg, water is easier in centrifugal action It is lower towards bucket wall 211 away from bucket bottom 212 an end motion, i.e., water is easier moves to drip ring 220, so, the discharge of water effect Rate is higher, but is washed when being unfavorable for that keg 210 slowly runs, and easily causes current water more when keg 210 slowly runs, So that clean result is not good, therefore, the angle between bucket wall 211 and the bucket bottom 212 is unsuitable excessive, 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 °, so, is made 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 are not easily runed off keg 210, and are made Obtaining washings can more concentrate on the middle part of keg 210, and then cause clean result more preferably.It should be noted that for general Logical washing machine 10, through manufacturing experimently comparisons repeatedly, using with 91 ° of bucket walls 211 of angle and bucket bottom 212, and aperture is 3mm Osculum 223, both are engaged, and have taken into account clean result of the keg 210 when slowly running and keg 210 in high-speed rotation When drainage efficiency so that 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 in subsequent washing process, through osculum 223 again Flow into keg 210, it is to avoid the waste of washings so that clean result is more preferably；Under dewatering state, keg 210 rotates at a high speed, small The rapid bucket wall 211 along 91 ° of water in bucket 210 climbs upwards, enters back cavity 201 by osculum 223, and revolve in high speed Thrown away to keg 210 from bung 213 from back cavity 201 under the centrifugal action for turning, realize dehydration.Due to keg 210 Barrel and the integrally connected at bucket bottom 212 so that keg 210 is isolated from the outside, " draining " and " dehydration " by a high speed rotate to Upper " getting rid of " goes out outside keg 210, into interior bucket 100, is discharged through the drainage system of interior bucket 100, has effectively prevented keg 210 The cross pollution of inside and outside water.
