Description

一种洗衣机波轮及其洗衣机Washing machine pulsator and washing machine thereof 技术领域Technical field
本发明属于洗衣机装置领域,具体地说,涉及一种洗衣机波轮及其洗衣机。The invention belongs to the field of washing machine devices, and in particular to a washing machine pulsator and a washing machine thereof.
背景技术Background technique
当前社会中,家用电器的洗衣机已经成为了人们生活中不可或缺的一部分,洗衣机的种类也开始变得越来越多,包括波轮洗衣机、滚筒洗衣机、洗干一体机等等。其中波轮洗衣机依然被大量的客户使用着,也开发了洗干一体的波轮洗衣机,同时客户对使用波轮洗衣机的要求也越来越高。现有的波轮洗衣机的波轮,一般设有3-6个搅拌叶结构,各搅拌叶的面积相对较小,且一般造型较平,洗涤性能不高,同时也不利于衣物的翻转,对于洗干一体机来说,干衣时间,干衣效果差且不均匀,还产生大量褶皱。In the current society, washing machines for household appliances have become an indispensable part of people's lives, and the types of washing machines have begun to become more and more, including pulsator washing machines, drum washing machines, washing and drying machines, and so on. Among them, the pulsator washing machine is still used by a large number of customers, and the washing machine is also developed. At the same time, the requirements for the use of the pulsator washing machine are getting higher and higher. The pulsator of the existing pulsator washing machine generally has 3-6 stirring blade structures, and the area of each stirring blade is relatively small, and the general shape is relatively flat, the washing performance is not high, and it is also unfavorable for the turning of the clothes. In the case of the washing and drying machine, the drying time is poor and uneven, and a large amount of wrinkles are generated.
此外,波轮洗衣机主要靠波轮的搅拌来带动衣物洗涤,为了防止缠绕,一般会在波轮中间设置自由旋转的转轮,目前转轮多数是沿波轮上设置的中心轴旋转,或者沿和波轮连接的中心轴旋转,底部旋转时在重力作用下和波轮的表面接触,在转动时受到摩擦力,塑料之间的摩擦系数比较大,时间长了有损坏的隐患;此外,中心转轮底部与波轮表面之间存在空隙,中心转轮旋转时容易产生偏离,导致中心转轮与波轮表面局部摩擦频繁,产生磨损或者其他方向产生更大空隙,容易卡衣物或者毛絮等,使得中心转轮摩擦力更大、更易损坏。In addition, the pulsator washing machine mainly relies on the agitation of the pulsator to drive the laundry to wash. In order to prevent the entanglement, a freely rotating wheel is generally arranged in the middle of the pulsator. At present, most of the runners are rotated along the central axis provided on the pulsator, or along the The central axis connected to the pulsator rotates, and when the bottom rotates, it is in contact with the surface of the pulsator under the action of gravity, and is subjected to friction during rotation. The friction coefficient between the plastics is relatively large, and the time is long and there is a hidden danger of damage; There is a gap between the bottom of the runner and the surface of the pulsator. When the center wheel rotates, it is easy to deviate, resulting in frequent local friction between the center wheel and the pulsator surface, resulting in wear or other gaps in other directions, and it is easy to get clothes or batt. This makes the center wheel more frictional and more susceptible to damage.
有鉴于此特提出本发明。The present invention has been made in view of the above.

具体实施方式Detailed ways
为使本发明实施例的目的、技术方案和优点更加清楚,下面将结合本发明实施例中的附图,对实施例中的技术方案进行清楚、完整地描述,以下实施例用于说明本发明,但不用来限制本发明的范围。The embodiments of the present invention will be clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is not intended to limit the scope of the invention.
如图1-图6所示,本发明提供一种洗衣机波轮,包括波轮本体1,该波轮本体1的中心设置可自由转动的中心转轮3和设置在中心转轮3下降低中心转轮和波轮之间摩擦的光滑支撑结构。As shown in FIG. 1 to FIG. 6 , the present invention provides a washing machine pulsator comprising a pulsator body 1 , a centrally rotatable center wheel 3 disposed at a center of the pulsator body 1 and a lower center disposed under the center wheel 3 A smooth support structure that rubs between the runner and the pulsator.
在上述方案中,一般情况下波轮洗衣机主要靠波轮的搅拌来带动衣物洗涤,但衣物在中心处不容易被打散,且十分容易缠绕在一起,为了解决缠绕的问题,一般会在波轮中心设置自由旋转的转轮,本发明在波轮中心设置了自由转动的中心转轮3,使得衣物容易被打散且不会缠绕,增强洗涤效果。但是,由于中心转轮3是沿波轮上的中心轴旋转的,或者沿和波轮连接的中心轴旋转,中心转轮3底部在重力作用下和波轮的表面接触,在转动时受到摩擦力,塑料之间的摩擦系数比较大,时间长了有损坏的隐患;此外,传统的中心转轮底部与波轮表面之间存在空隙,中心转轮旋转时容易产生偏离,导致中心转轮与波轮表面局部摩擦频繁,产生磨损或者其他方向产生更大空隙,容易卡衣物或者毛絮等,使得中心转轮摩擦力更大、更易损坏。而波轮的拆卸和更换又需要专业人士操作,客户很难自行拆卸更换,这就为客户增添了烦恼。本发明设置光滑支撑结构,降低中心转轮与波轮之间的摩擦,使中心处水流简单规律,衣物不缠绕,增强洗涤效果,还减小了中心转轮3摩擦波轮表面导致的损坏。所述光滑支撑结构可设置在波轮上,也可设置在中心转轮3上,优选设置在波轮上。In the above scheme, in general, the pulsator washing machine mainly relies on the agitation of the pulsator to drive the laundry to be washed, but the laundry is not easily broken at the center, and is easily entangled together, in order to solve the problem of entanglement, generally in the wave The center of the wheel is provided with a freely rotating wheel. The present invention is provided with a freely rotating center wheel 3 at the center of the wheel, so that the clothes are easily broken up and not entangled, enhancing the washing effect. However, since the center wheel 3 is rotated along the central axis on the pulsator or rotates along the central axis connected to the pulsator, the bottom of the center wheel 3 is in contact with the surface of the pulsator under the action of gravity, and is subjected to friction during rotation. The friction coefficient between the force and the plastic is relatively large, and the time is long and there is a hidden danger. In addition, there is a gap between the bottom of the traditional center wheel and the surface of the pulsator, and the center wheel is prone to deviation when rotating, resulting in the center wheel and The surface of the pulsator is frequently rubbed locally, causing wear or other voids in other directions, and it is easy to get clothes or batt, which makes the center wheel more frictional and more susceptible to damage. The disassembly and replacement of the pulsator requires professional operation, and it is difficult for the customer to disassemble and replace it, which adds trouble to the customer. The invention provides a smooth support structure, reduces the friction between the center runner and the pulsator, makes the water flow at the center simple, the clothes are not entangled, enhances the washing effect, and reduces the damage caused by the friction wheel surface of the center runner 3. The smooth support structure may be disposed on the pulsator or on the center wheel 3, preferably on the pulsator.
进一步的,所述光滑支撑结构可拆卸的连接在波轮本体1上,所述中心转轮3可旋转的设置在光滑支撑结构上方。Further, the smooth support structure is detachably coupled to the pulsator body 1, and the center wheel 3 is rotatably disposed above the smooth support structure.
进一步的,所述光滑支撑结构外边缘直径大于等于中心转轮3底部外直径。Further, the outer edge diameter of the smooth support structure is greater than or equal to the outer diameter of the bottom of the center runner 3.
在上述方案中,所述光滑支撑结构外边缘直径大于等于中心转轮3底部外直径,防止中心转轮3底部接触到波轮。所述光滑支撑结构将中心转轮3底部与波轮本体1隔离开。In the above solution, the outer edge diameter of the smooth support structure is greater than or equal to the outer diameter of the bottom of the center runner 3, and the bottom of the center runner 3 is prevented from contacting the pulsator. The smooth support structure isolates the bottom of the center wheel 3 from the pulsator body 1.
进一步的,所述光滑支撑结构为金属垫片4,该金属垫片4卡接或者螺纹连接或者通过 螺钉41连接在波轮本体1上。Further, the smooth support structure is a metal spacer 4 that is snapped or screwed or connected to the pulsator body 1 by screws 41.
在上述方案中,所述光滑支撑结构为金属垫片4,因为金属与塑料之间的摩擦系数低,金属垫片4在防止中心转轮3底部磨损波轮的同时,不增加中心转轮3的阻力,使得中心转轮3的转动不受影响。In the above solution, the smooth support structure is a metal gasket 4, because the friction coefficient between the metal and the plastic is low, and the metal gasket 4 does not increase the center runner 3 while preventing the bottom of the center runner 3 from wearing the pulsator 3 The resistance makes the rotation of the center wheel 3 unaffected.
进一步的,所述中心转轮3为半球状结构,中心转轮3表面设有若干凸块31,优选的,所述凸块31均匀周向设置在中心转轮3表面。优选的,所述中心转轮3为中空的球状结构,内部设有若干增加强度和起到支撑作用的筋,中心转轮3顶部21可拆卸的设有转轮盖32。Further, the center wheel 3 has a hemispherical structure, and the surface of the center wheel 3 is provided with a plurality of protrusions 31. Preferably, the protrusions 31 are uniformly circumferentially disposed on the surface of the center wheel 3. Preferably, the center wheel 3 has a hollow spherical structure, and a plurality of ribs for increasing strength and supporting functions are disposed inside, and a top cover 21 of the center wheel 3 is detachably provided with a wheel cover 32.
在上述方案中,所述中心转轮3上设有凸块31,增强了中心转轮3对衣物的翻转作用,防止衣物在中心处堆积缠绕。所述凸块31沿中心转轮3表面均匀周向延伸,在中心转轮3表面设置两周或以上该凸块31。中空的中心转轮3减轻了质量。同时为金属垫片4的安装提供了空间,与金属垫片4的接触面积也不大。所述转轮盖32卡接在中心转轮3上。In the above solution, the center wheel 3 is provided with a bump 31, which enhances the turning effect of the center wheel 3 on the clothes, and prevents the clothes from being entangled at the center. The bump 31 extends uniformly circumferentially along the surface of the center wheel 3, and the bump 31 is provided on the surface of the center wheel 3 for two weeks or more. The hollow center wheel 3 reduces the mass. At the same time, space is provided for the installation of the metal spacer 4, and the contact area with the metal spacer 4 is not large. The wheel cover 32 is snapped onto the center wheel 3.
进一步的,包括波轮本体1,所述波轮本体1上设置两个从中心沿波轮本体1的径向延伸的凸起的搅拌叶2,两个搅拌叶2径向延伸在同一直径上。Further, the pulsator body 1 is provided, and the pulsator body 1 is provided with two protruding stirring blades 2 extending from the center along the radial direction of the pulsator body 1. The two stirring blades 2 extend radially on the same diameter. .
在上述方案中,因为现有的洗衣机波轮一般设置3-6个搅拌叶2,导致搅拌叶2的大小相对来说偏小,且造型受限,一般造型比较平,不利于衣物的翻转,容易导致衣物缠绕,洗涤效果不佳。传统洗衣机波轮为了增强洗涤效果,设置多个搅拌叶2,但增加搅拌叶2在增多水流与衣物摩擦的同时也使水流变得复杂,加之增多的搅拌叶2减小了衣物分布的空间,使得衣物容易缠绕,导致洗涤效果差。本发明设置两个从中心沿波轮本体1的径向延伸的凸起的搅拌叶2,两个搅拌叶2径向延伸在同一直径上,为衣物的水平翻转提供了空间的同时也使得搅拌叶2更容易将衣物打散,更容易将衣物翻转,增加了洗涤效果,同时也为洗干一体的波轮洗衣机增加烘干均匀度和烘干效果,同时避免缠绕,干衣后衣物上的皱褶少;本发明所述的波轮搅拌叶2既能保证洗涤水流的方向简单强度高,同时又为衣物增加了分布的空间,使得简单的高强度水流与衣物之间充分摩擦接触,且衣物散开不易缠绕,大大提高了洗涤和/或烘干效果;在脱水时,可供衣物分布的空间大,衣物更容易散开,不缠绕,脱水效果好。再者,本发明的搅拌叶2相对普通波轮搅拌叶2高,增加了搅拌叶2对水流的冲击和搅拌作用,使洗涤剂等可以与水充分混合,提高洗衣机的清洗效果。In the above solution, since the existing washing machine pulsator is generally provided with 3-6 stirring blades 2, the size of the stirring blade 2 is relatively small, and the shape is limited, and the general shape is relatively flat, which is not conducive to the turning of the clothes. It is easy to cause the clothes to entangle and the washing effect is not good. In order to enhance the washing effect, the conventional washing machine pulsator is provided with a plurality of stirring blades 2, but increasing the stirring blade 2 complicates the water flow while increasing the water flow and the friction of the clothes, and the increased stirring blade 2 reduces the space for the distribution of the clothes. The clothes are easily entangled, resulting in poor washing performance. The present invention provides two raised agitating blades 2 extending from the center along the radial direction of the pulsator body 1, the two agitating blades 2 extending radially on the same diameter, providing space for the horizontal inversion of the laundry while also agitating Leaf 2 makes it easier to break up the clothes, it is easier to turn the clothes over, which increases the washing effect. At the same time, it also increases the drying uniformity and drying effect for the washing machine, while avoiding entanglement and drying on clothes. The wrinkle agitating blade 2 of the present invention can ensure the direction of the washing water flow to be simple and high, and at the same time increase the distribution space for the laundry, so that the simple high-intensity water flow and the laundry are in sufficient frictional contact, and The clothes are not easily entangled, which greatly improves the washing and/or drying effect; when dewatering, the space for the clothes to be distributed is large, the clothes are more easily scattered, the entanglement is not performed, and the dehydration effect is good. Furthermore, the stirring blade 2 of the present invention is higher than the ordinary pulsator stirring blade 2, and increases the impact and agitation of the stirring blade 2 on the water flow, so that the detergent or the like can be sufficiently mixed with the water to improve the washing effect of the washing machine.
进一步的,所述搅拌叶2底部宽,向顶部逐渐收窄,所述搅拌叶2包括从顶部21开始向波轮底盘11延伸的第一侧面22和第二侧面23,所述第一侧面22和第二侧面23位于搅拌叶2的径向两侧,所述第一侧面22和第二侧面23与波轮本体1相交的曲线基本与该搅拌叶2 的径向平行。所述第一侧面22和第二侧面23与波轮本体1相交的曲线与该搅拌叶的径向之间的偏离角度小于等于6°,且两者偏离方向沿径向相反。Further, the agitating blade 2 is wide at the bottom and gradually narrows toward the top, and the agitating blade 2 includes a first side 22 and a second side 23 extending from the top 21 toward the pulsator chassis 11, the first side 22 The second side face 23 is located on both sides of the radial direction of the stirring blade 2, and the curve of the first side face 22 and the second side face 23 intersecting the pulsator body 1 is substantially parallel to the radial direction of the stirring blade 2.

在上述方案中,传统的波轮搅拌叶设计成从中心到外边缘逐渐变宽的造型,但这种类型的搅拌叶占用波轮空间大,水流顺着搅拌叶的延伸方向不断改变方向形成不同的水流,容易造成水流紊乱,且各方向水流之间互相作用削弱水流强度,衣物在中心处极易缠绕打结,水流与衣物之间的摩擦也不强,产生的水流弱且方向均不同,可供衣物翻转的空间小,衣物易在中心区域缠绕打结。本发明设置两个径向延伸且在同一直径上的搅拌叶2,且搅拌叶2第一侧面22和第二侧面23与波轮本体1相交的曲线基本与该搅拌叶2的径向平行,使得搅拌叶2带动水流自中心向外逐渐增强,且水流方向简单基本不变,产生同一方向逐渐增强的纯净水流,增强洗涤效果的同时使得衣物不易堆积在中心位置发生缠绕打结。第一侧面22和第二侧面23向底盘11平滑过渡,使得搅拌叶2表面不会有刮擦衣物的凸起的同时保持了可翻转衣物的形状,还减小了搅拌叶2对衣物的阻力。In the above scheme, the conventional pulsator stirring blade is designed to gradually widen from the center to the outer edge, but this type of stirring blade occupies a large space of the pulsator, and the water flow continuously changes direction along the extending direction of the stirring blade to form a different shape. The water flow is easy to cause water flow disorder, and the interaction between the water flows in all directions weakens the water flow intensity. The clothes are easily entangled and knotted at the center, the friction between the water flow and the clothes is not strong, and the generated water flow is weak and the directions are different.

在上述方案中,所述第一侧面22和第二侧面23为非对称的形状,第一侧面22和第二侧面23的陡度不同,且所述搅拌叶2中心对称,使得洗衣机波轮在正反转的过程中,搅拌叶2对衣物产生两种不同的作用,搅拌叶2之间的衣物也受到两种不同的作用,防止衣物缠绕,同时更加容易翻转衣物。第一侧面22和第二侧面23可以均为斜面或者均为曲面或者一个为曲面一个为斜面。In the above solution, the first side surface 22 and the second side surface 23 have an asymmetrical shape, the steepness of the first side surface 22 and the second side surface 23 are different, and the stirring blade 2 is center-symmetrical, so that the washing machine pulsator is In the process of reversing, the stirring blade 2 exerts two different effects on the laundry, and the laundry between the stirring blades 2 is also subjected to two different functions, preventing the clothing from being entangled, and at the same time, it is easier to turn the laundry. The first side 22 and the second side 23 may both be beveled or both curved or one curved and one beveled.
进一步的,所述搅拌叶2还包括从顶部21开始向波轮底盘11延伸的内侧面24和外侧面25,所述内侧面24向波轮中心方向延伸,所述外侧面25向波轮外边缘延伸,所述内侧面24和外侧面25与波轮本体1相交的曲线形成搅拌叶内边缘和搅拌叶外边缘,两者的长度基本相同。所述内侧面24和外侧面25分别与第一侧面22和第二侧面23圆滑过渡。所述内侧面24自顶部21开始迅速向波轮中心区的底盘11延伸,所述外侧面25自顶部21开始迅速向底盘11外边缘延伸。所述搅拌叶2外边缘的长度为波轮底盘11外圆周长的5%-30%。所述搅拌叶2内边缘包裹中心转轮3的长度大于搅拌叶2外边缘长度的20%,所述搅拌叶2外边缘与底盘11外边缘之间的距离小于10mm,每个搅拌叶2的面积占整个波轮底盘11面积的百分比大于10%。Further, the agitating blade 2 further includes an inner side surface 24 and an outer side surface 25 extending from the top portion 21 toward the pulsator chassis 11, the inner side surface 24 extending toward the pulsator center direction, and the outer side surface 25 facing the pulsator The edges extend, and the curve intersecting the inner side 24 and the outer side 25 with the pulsator body 1 forms the inner edge of the stirring blade and the outer edge of the stirring blade, both of which are substantially the same length.

Compared with the stirring blade 2 which is far smaller than the outer edge, the stirring blade 2 of the invention obviously enhances the water flow intensity at the inner edge of the stirring blade 2, and the water flow is simple and does not cause entanglement. When drying, the stirring blade 2 of the present invention is very It is easy to spread the clothes in the upper and lower, middle and other spaces to avoid entanglement, and the drying effect is good and the wrinkles are less.

The outer side surface 25 rapidly extends from the top portion 21 toward the outer edge of the chassis 11, the angle of inclination of the outer side surface 25 is large, and as close as possible to the outer edge of the chassis 11, enhancing the flipping action of the laundry at the edge of the washing tub to prevent the laundry from being in the washing tub. The edges remain or accumulate, increasing the washing and/or drying effect. The inner side surface 24 and the outer side surface 25 may both be beveled or curved or one beveled and curved. The distance between the outer edge of the stirring blade 2 and the outer edge of the chassis 11 is less than 10 mm, which enhances the flipping action of the laundry at the edge of the washing tub, prevents the laundry from remaining or accumulating at the edge of the washing tub, and increases the washing and drying effect.

在上述方案中,所述通孔既可作为通水孔增加洗涤时内外桶之间的水循环量,又可作为烘干风进风口提高烘干作用,还增强了波轮的美观效果。再者,洗涤时,离心渐开分布的通孔产生若干离心渐开方向的小水流,防止衣物缠绕,同时增加水流与衣物的接触摩擦面积,洗涤效果更好。In the above solution, the through hole can be used as a water passage hole to increase the water circulation between the inner and outer barrels during washing, and can also be used as a drying air inlet to improve the drying effect, and also enhance the aesthetic effect of the pulsator. Moreover, during washing, the centrifugally inflated through-holes generate a small flow of water in a centrifugally involute direction to prevent the clothes from being entangled, and at the same time increase the contact friction area between the water flow and the laundry, and the washing effect is better.
