The clothes opening of the inner drum of the top-loading drum washing machine is set on the inner cylinder. Both inner cylinder caps are closed. It has smaller flanges and main shafts, and the left and right sides of the inner drum have main shaft support. Therefore, the support structure of the inner drum is stronger than the front drum washing machine inner drum, and it also has the water saving and high performance of the drum washing machine. The washing ratio and the advantages of the pulsator washing machine without having to bend over to get clothes. At the same capacity, the top-loading drum washing machine has a thinner body and saves space. Therefore, the top-loading drum washing machine has received greater attention. Europe and other places are more popular and have a certain market size.
为了提高洗涤效果,现有技术存在一种洗衣机,其在筒体的前盖和/或后盖设置拨水筋,并将拨水筋在前盖和/或后盖的径向延伸,从而利用拨水筋进行衣物及水流的提升、摩擦作用,进而提高洗涤效果;但该种现有技术的拨水筋的设置会导致筒体整体强度的下降,这不利于洗衣机的结构稳定。In order to improve the washing effect, there is a washing machine in the prior art, which is provided with a water repellent rib on the front cover and / or the rear cover of the drum body, and the water repellent rib is extended in the radial direction of the front cover and / or the rear cover, thereby utilizing The water repellent ribs perform the lifting and friction of clothes and water flow, thereby improving the washing effect.

下面参考图1-图8描述根据本公开实施例的内筒组件400。The inner cylinder assembly 400 according to an embodiment of the present disclosure is described below with reference to FIGS. 1 to 8.
如图1-图8所示,根据本公开一个实施例的内筒组件400包括:筒体40和至少一个端盖。As shown in FIGS. 1 to 8, the inner cylinder assembly 400 according to an embodiment of the present disclosure includes a cylinder 40 and at least one end cover.
筒体40具有开口,端盖用于封闭筒体40的至少一个开口,其中,端盖包括至少一个加强面,加强面设有至少一个朝向筒体40内凸出的拨水筋47,且拨水筋47不超出加强面的边缘,即拨水筋47不跨出加强面的边缘。The cylinder 40 has an opening, and the end cover is used to close at least one opening of the cylinder 40, wherein the end cover includes at least one reinforcing surface, and the reinforcing surface is provided with at least one water repellent rib 47 protruding toward the inside of the cylinder 40, and The water rib 47 does not exceed the edge of the reinforcing surface, that is, the water repellent rib 47 does not step beyond the edge of the reinforcing surface.
根据本公开实施例的内筒组件400,通过在端盖上设置加强面,并在加强面上设置朝向筒体40内凸出的拨水筋47,拨水筋47可以增加水流冲刷衣物的效果,从而提高了洗涤性能;且由于拨水筋47不超出加强面的边缘,提高了内筒组件400的一阶模态频率,在不增加成本的情况下加强了内筒组件400的刚度和强度,使其可以满足大容量、高转速滚筒洗衣机100的刚度和强度需求,同时结构更加美观,提高了用户的使用体验。According to the inner tube assembly 400 according to the embodiment of the present disclosure, by providing a reinforcing surface on the end cover, and providing a water-repellent rib 47 protruding toward the inside of the cylinder 40 on the reinforcing surface, the water-repellent rib 47 can increase the effect of water flowing over the clothes. Therefore, the washing performance is improved; and because the water repellent rib 47 does not exceed the edge of the reinforcing surface, the first-order modal frequency of the inner tube assembly 400 is increased, and the rigidity and strength of the inner tube assembly 400 are enhanced without increasing costs. It can meet the rigidity and strength requirements of the large-capacity, high-speed drum washing machine 100, meanwhile, the structure is more beautiful, and the user experience is improved.

By stamping and forming the structure of the water-repellent ribs 47 on the end cap, the structural strength of the end cap can be increased to a certain extent without thickening the end. The thickness of the cover does not increase additional material costs, and only adds a stamping step on the basis of the existing end cover. The operation is simple, the molding is convenient, and it is easy to promote the use.
根据本公开的一个实施例,加强面的纵截面轮廓线与筒体40的轴线不垂直,即加强面的至少一部分凸出端盖,加强面相对于竖直平面不平行布置,进而使端盖上具有一定的斜度,通过对加强面的优化,使得端盖的刚度和强度得到提升,以使其应用在大容 量、高转速滚筒洗衣机100上,满足高刚度和强度需求。According to an embodiment of the present disclosure, the longitudinal profile of the reinforcing surface is not perpendicular to the axis of the cylinder 40, that is, at least a part of the reinforcing surface protrudes from the end cover, and the reinforcing surface is arranged non-parallel with respect to the vertical plane. With a certain slope, the rigidity and strength of the end cover can be improved by optimizing the reinforcing surface, so that it can be applied to a large-capacity, high-speed drum washing machine 100 to meet high rigidity and strength requirements.
如图5-图7所示,根据本公开的一个实施例,加强面包括第一加强面421和第二加强面422,第一加强面421和第二加强面422分别形成环形,且第一加强面421位于第二加强面422的外侧,第一加强面421和第二加强面422不共面,从而在端盖的外表面的与第一加强面421和第二加强面422连接处对应的位置形成环状的倾斜台阶,使得端盖的刚度和强度得到提升,在第一加强面421或第二加强面422上单独设置拨水筋47,即设在第一加强面421上的拨水筋47不跨设到第二加强面422,设在第二加强面422上的拨水筋47不跨设到第一加强面421,使得端盖的刚度和强度可以得到进一步的提升,以使其应用在大容量、高转速滚筒洗衣机100上,满足高刚度和强度需求。As shown in FIGS. 5-7, according to an embodiment of the present disclosure, the reinforcing surface includes a first reinforcing surface 421 and a second reinforcing surface 422, the first reinforcing surface 421 and the second reinforcing surface 422 form a ring shape, respectively, and the first The reinforcing surface 421 is located outside the second reinforcing surface 422, and the first reinforcing surface 421 and the second reinforcing surface 422 are not coplanar, so that the outer surface of the end cap corresponds to the connection between the first reinforcing surface 421 and the second reinforcing surface 422. An annular inclined step is formed at the position to increase the rigidity and strength of the end cap. A water-repellent rib 47 is separately provided on the first reinforcing surface 421 or the second reinforcing surface 422, that is, the dial provided on the first reinforcing surface 421. Water ribs 47 do not cross to the second reinforcing surface 422, and the water repellent ribs 47 provided on the second reinforcing surface 422 do not cross to the first reinforcing surface 421, so that the rigidity and strength of the end cap can be further improved. It is applied to a large-capacity, high-speed drum washing machine 100 to meet the requirements of high rigidity and strength.
在一些示例中,拨水筋47包括多个第一拨水筋,第一拨水筋沿第一加强面421的周向间隔布置,每个第一拨水筋单独形成在第一加强面421上,多个第一拨水筋不连通,且第一拨水筋不超出第一加强面421的内外边缘,从而可以避免设置多个第一拨水筋对第一加强面421刚度和强度造成影响。In some examples, the water-repellent ribs 47 include a plurality of first water-repellent ribs. The first water-repellent ribs are arranged at intervals along the circumferential direction of the first reinforcing surface 421, and each of the first water-repellent ribs is separately formed on the first reinforcing surface 421. In the above, the plurality of first water-repellent ribs are not connected, and the first water-repellent ribs do not exceed the inner and outer edges of the first reinforcing surface 421, so that the plurality of first water-repellent ribs can be prevented from causing stiffness and strength of the first reinforcing surface 421. influences.
在另一些示例中,拨水筋47包括多个第二拨水筋(图中未示出),多个第二拨水筋沿第二加强面422的周向间隔布置,每个第二拨水筋也单独形成在第二加强面422上,且第二拨水筋不超出第二加强面422的内外边缘,从而避免降低第二加强面422的刚度和强度。In other examples, the water-repellent ribs 47 include a plurality of second water-repellent ribs (not shown in the figure).
