In order to further fix the sealing ring 240, for example, circumferential surface of the groove 224 along Drainage Division 222 is set, example Such as, the groove 224 is annular groove 224, for example, the minimum diameter of the annular groove 224 is more than the interior of the sealing ring 240 Footpath, because the sealing ring 240 is flexible, therefore, 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 enclosed in 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 sealing effectiveness to drip ring 220 and bucket wall 211 of sealing ring 240 not good, in order to avoid Not good to the sealing effectiveness of drip ring 220 and 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 in the diameter in the section of the sealing ring 240, 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 are entirely sealed The diameter of closed loop.Specifically, because the thickness of sealing ring 240 in the present embodiment is more than the depth of groove 224, therefore so that should When sealing ring 240 is placed in the groove 224, at least part is exposed or is raised in the groove 224, and then causes the sealing ring 240 effectively increase with the contact area of bucket wall 211, and then closely to abut 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 to which in 210 high-speed rotation of keg, water can be discharged efficiently, and 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, some osculums 223 are uniformly arranged around the center of circle of the circular cross-section of the Drainage Division 222, so, when Drainage Division 222 During with 210 high-speed rotation of keg, the water in keg 210 can be discharged along equally distributed osculum 223, and then be caused small Water in bucket 210 efficiently, can be discharged equably so that dehydrating effect is more preferably.

In order that osculum 223 drainage effect more preferably, for example, the aperture of the osculum 223 be 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 causes draining to be discharged from osculum 223 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 discharge from osculum 223 so that clean result more preferably, on the other hand, then causes keg 210 to exist 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 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 Chamber 201 is flowed, 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 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 outer circumferential surface of the sealing ring 240 along Drainage Division 222 is set, so, when Drainage Division 222 passes through sealing ring 240 are connected to inside barrel wall 211, keg 210 and are 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 close to 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 make it that dewatering efficiency is higher, for example, referring again to Fig. 5, the draining The distance that portion 222 abuts position to the edge of bung 213 of the interior sidewall surface of the bucket wall 211 is 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, in other words, during the depth of the back cavity 201 is 50mm, the present embodiment, back cavity 201 Highly it is sealing ring 240 and bung 213 apart from L.It is noted that the height of the back cavity 201 is unsuitable excessive, backflow The height of chamber 201 is excessive then to cause keg 210 when high-speed rotation, and the water in back cavity 201 is not easy to get rid of from bung 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 cause 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 is not good.Therefore, in the present embodiment, the drip ring 220 is connected to the position of the bucket wall 211 and the bung 213 It is preferably 50mm apart from L, i.e., the depth of the back cavity 201 is 50mm, 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 can be fast Bung 213 is thrown away fastly.
