Abstract
The invention relates to a single-tube washing machine and in particular to the improvement of a single tube of a single-tube washing machine. No washing water exists between an outer tube and the single tube of the single-tube washing machine, so that energy and water can be saved; and moreover, no interlayer pollution exists between the outer tube and the single tube. The existing single-tube washing machine adopting opening-closing devices to correspond to dehydrating holes one by one is provided with few dehydrating holes because of worrying about the water leakage problem, and the wall nearby the dehydrating holes is inclined insufficiently, so that the dehydrating effect is generally poor. The single-tube washing machine is characterized in that the wall of the single tube 1 is provided with 3*12 dehydrating holes, wherein an opening-closing device 3 is respectively arranged outside each dehydrating hole, and tube walls 2 and 5 at each dehydrating hole are protruded towards the outside of the single tube so as to gather the washing water to the dehydrating hole in dehydration. An angle alpha of tube walls at each dehydrating hole is about 160 DEG, thus the tube wall at the dehydrating hole can be sufficiently inclined when protruding towards the outside of the single tube, and a plurality of dehydrating holes are provided, so that the dehydrating effect is good.
Description
Technical field
The present invention relates to the particularly a kind of improvement of Washing dewatering tub of single container washing machine of a kind of washing machine.
Background technology
Single container washing machine generally includes the outer barrel of collecting washings and is rotatably installed in and integrates single barrel of washing dehydration function in the described outer barrel.Since between single barrel and the outer barrel without washings, therefore it not only energy-saving and water-saving but also the more important thing is do not have outer barrel with single barrel between the interlayer pollution, but the dewatering hole of single container washing machine is generally than dewatering hole much less on the sleeve type washing machine dehydration barrel, the strength towards the dewatering hole place that is subject to during from the local washings dehydration of dewatering hole away from is not enough, the problem of ubiquity costs and poor dehydration results.For example, number of patent application is that 200610087784.1 Chinese patent has disclosed a kind of roller washing machine, it comprises outer barrel (shell) and is rotatably installed in described outer barrel interior rotatingcylindrical drum and opening and closing device, opening and closing device is comprised of elastomeric element (elastic webbing) and switching parts (bead) with suitable weight, on the cylinder bucket wall a plurality of dewatering holes are arranged, open and close parts between dewatering hole and elastomeric element, opening and closing device opens or closes dewatering hole according to the centrifugal force intensity that drum rotating produces.The problem that this invention exists is: because the bucket wall between dewatering hole and the dewatering hole is circular arc, therefore flow to " centrifugal force " that barrel washings at wall place are subject to when dewatering and do not have tangential component, be difficult to flow to the dewatering hole place, therefore the dewatering hole spacing of this invention is established littlely, close with the dewatering hole spacing of sleeve type washing machine dehydration barrel, thereby quantity is more and concentrated setting is anterior to cylinder, thereby the clothes dewatering effect of cylinder postmedian is relatively poor.And for example, publication number is that the WTO patent of invention of WO0204734A1 has disclosed a kind of improved roller washing machine, its principle as shown in Figure 1, single barrel of 1(cylinder) sidewall roughly is cydariform, Fig. 1 is single barrel of 1 sidewall middle part (convex camber) diagrammatic cross-sectional view in a circumferential direction, be many (eight) limit shape in the place that single barrel of 1 sidewall bloats, establish dewatering hole 4 and opening and closing device 3 at polygonal each place, angle.Washings are pooled to first bloating of middle part during dehydration from the cylinder front and rear part, are pooled to each dewatering hole 4 place by polygonal limit again and discharge.Bucket wall 2 between the dewatering hole 4 of this invention, 5 is straight line or planar shaped (be that groove or plane decide on the place that bloats), angle β is 180 degree between the bucket outer wall 2 and 5 in other words, therefore flowing to " centrifugal force " that the washings at two dewatering hole mid portion bucket wall c places are subject to when dewatering does not have tangential component, is difficult to dewatering hole 4 places diffluence.Although " centrifugal force " tangential component that 4 place's washings are subject to from c to dewatering hole increases gradually, but the degree that increases is also not obvious and can not free adjustment " centrifugal force " tangential component, moreover also has the obstruct of clothing, thereby washings also are difficult to flow to dewatering hole 4 places, therefore dehydrating effect is still bad, is difficult to satisfy customer requirements.
Summary of the invention
In order to overcome the problem of the single barrel of costs and poor dehydration results that has single container washing machine now, the invention provides a kind of single container washing machine, it can freely improve " centrifugal force " tangential component that washings are subject within the specific limits, thus dehydrating effect is good.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of single container washing machine shown in Fig. 2,3, comprises single barrel 1, and a plurality of dewatering holes 4 are arranged on the single barrel of wall, and dewatering hole 4 outer wall places are provided with opening and closing device 3, and opening and closing device 3 is closed dewatering hole 4 when washing, open dewatering hole 4 when dehydration.Improvement project of the present invention is: dewatering hole 4 place's bucket walls 2,5 take dewatering hole 4 as the top to single barrel of 1 outer protrusion and so that between the adjacent dewatering hole 4 the angle α between the bucket wall outer wall 2,5 less than 180 degree, the bucket wall 2,5 that protrudes can be the plane, it also can be curved surface, if curved surface as shown in Figure 4, then the angle between the bucket wall outer wall 2,5 refers to the angle α that section, each point place consists of on barrel wall outer wall 2,5.Dewatering hole 4 is evenly distributed on single barrel of 1 barrel of wall, and dewatering hole 4 quantity generally are made as 2～5(fore-and-aft direction) * 9～15(circumferencial direction) individual, very little dehydrating effect bad, the too many probability that leaks increases and cost increases.Bucket wall outer wall 2,5 angle α generally can be chosen for 90～170 degree between the adjacent dewatering hole 4, and α is too large, and dehydrating effect is bad, and too little then so that single barrel of appearance and size increases, and the clothing distortion is serious after the dehydration.For the sake of simplicity, dewatering hole 4 place's bucket walls are outwardly generally tapered, and the bucket wall of this protrusion and former barrel of wall intersection form rectangle, and 0～3 centimetre of rectangle spacing, the purpose of choosing rectangle are the distances that reduces between the bucket wall 2,5, improve dehydrating effect.But, bucket wall 2 when single barrel 1,5 when being the plane, bucket wall 2,5 go up in the circumferential direction of the circle that washings everywhere are subject to towards " centrifugal force " component of dewatering hole 4 and different, O point place " centrifugal force " component is minimum, " centrifugal force " component is maximum near the dewatering hole 4, thereby cause dehydration inhomogeneous, we can allow the bucket wall 2 on single barrel of 1 dewatering hole, 4 place's circumferencial directions, 5 increase gradually near dewatering hole 4 places to the O place curvature of close single barrel of inside everywhere, as shown in Figure 4, thereby make the bucket wall 2 on dewatering hole 4 place's circumferencial directions, " centrifugal force " that is subject to during 5 washings dehydration everywhere equates towards the component of dewatering hole 4 directions, and all equals barrel wall 2,5 " centrifugal force " that are subject to during with the washings dehydration of place, centre position, O place for dewatering hole in the situation of plane 4 are towards the component of dewatering hole 4 directions.
The invention has the beneficial effects as follows: the present invention is owing to the angle α between the bucket wall outer wall 2,5 between the adjacent dewatering hole 4 spends less than 180, and can design arbitrarily within the specific limits as required the size of angle α, thereby can improve easily " centrifugal force " tangential component that washings are subject to, improved dehydrating effect, the quantity of dewatering hole 4 rationally is set, can further improve dehydrating effect.
