Description

一种洗衣机内桶底法兰盘结构及洗衣机 技术领域
本发明涉及洗衣机领域，特别涉及一种洗衣机内桶底部的法兰盘安装结构及具有该法兰盘安装结构的洗衣机。
背景技术
现有的洗衣机内桶、外桶之间是一个封闭的环境，只有水流可以通过，洗衣机内桶底为环形结构，内桶底下部安装有六角形法兰盘，包括本体和向外延伸的六个安装脚，圆盘本体与内桶轴连接，安装脚上设有螺钉安装脚，与内桶底配合螺钉固定连接，如申请号为200820038868.0的中国专利公开的一种套缸洗衣机脱水桶法兰安装结构。
由于洗衣机内外桶之间结构的局限性和使用环境的特殊性，因此在使用3-5个月之后，内桶外壁和外桶内壁上会粘附污垢，从而滋生不同程度的细菌，而滋生的细菌绝大部分是对人体有害的。
随着人们生活水平的提高和对生活质量要求的提高，洗衣机的卫生问题解决已经显的很迫切。相关科研机构对洗衣机内部环境的调查情况显示，洗衣机内部污染的严重性已经越来越受到消费者的重视。为了从根本上避免洗衣机对洗涤物的二次污垢，并且更好地对用户的健康负责，洗衣机内部环境的清洁难题已经是一个迫切需要攻克的问题。
申请人在中国申请201010160548.4中公开了一种使用柔性颗粒清洗洗衣机内外桶之间的洗衣机及方法,该洗衣机采用在洗衣机内外桶之间放置柔性颗粒,通过衣物洗涤过程中水的规律性流动带动柔性颗粒撞击和摩擦洗衣机内外桶壁,实现洗衣机内外桶之间的清洁。
但现有的波轮洗衣机内桶底结构，法兰盘通过安装脚固定在内桶底部，内桶底部中心开口区域与法兰盘主体同轴安装的位置保留有很大的透水空隙，即法兰盘主体的直径小于内桶底部中心开口区域的内径，该透水空隙能够使洗涤水在内桶和外桶之间流通，但也使得内外桶之间的柔性颗粒由此进入内桶，进而减少内外桶之间柔性颗粒的数量，影响了清洗内外桶壁的效果。
申请号为201210189616.9的中国专利公开了一种洗衣机内桶底部的法兰盘安装结构及洗衣机，该洗衣机具有清洁桶壁的功能，包括外桶和内桶，在外桶和内桶之间设有随水流浮动的清洗颗粒以清洁桶壁，内桶底部安装有能阻止清洗颗粒由底部进入内桶的法兰盘。法兰 盘包括主体和分布在主体周围与内桶固定的安装脚，内桶底部中心对应法兰盘主体的区域为上下相通的开口，所述的法兰盘主体直径大于等于开口的内径，或者法兰盘主体直径小于开口的内径，且法兰盘主体外边沿与开口的内边沿之间的缝隙大小满足能阻止清洗颗粒由该缝隙进入内桶。
上述结构通过扩大法兰盘主体尺寸封堵内桶底开口区域以避免清洗颗粒进入内桶，但该结构不利于水流的流动，包括洗涤时内外桶之间水流的流动和排水时排水的速度，并且在排水到最后时，线屑容易堆积在内桶底，不利于排出，从而滋生细菌。
有鉴于此特提出本发明。
发明内容
本发明要解决的技术问题在于克服现有技术的不足，提供一种能够在洗涤时阻止设置在内外桶之间的物体随水流由内桶底部中空开口进入内桶且在排水时不影响水流和线屑排出的法兰盘结构。
本发明的另一目的在于提供一种具有该法兰盘的洗衣机。
为解决上述技术问题，本发明采用技术方案的基本构思是：一种洗衣机内桶底法兰盘结构，法兰盘包括位于法兰盘中心的轴接部和位于轴接部外周与洗衣机内桶底固定连接的环形的安装部，安装部与轴接部之间设有多个连接部，连接部包括由安装部延伸至轴接部的主肋和分别设于主肋两侧沿主肋延伸方向依次排列的多个横筋，多个连接部配合构成安装部和轴接部之间区域的过滤部。
进一步的，所述的连接部自主肋沿横筋延伸方向向两侧渐低，两两相邻连接部之间构成V形凹部，V形凹部底端为两主肋的横筋之间间距形成的法兰盘上下通水的缺口。
进一步的，所述任一主肋同一侧的两两相邻横筋之间设有间隙。
进一步的，所述的主肋上表面为一弧形表面，从中心向两侧圆弧过渡降低，与两侧的横筋平滑过渡连接。
进一步的，所述的横筋一端与主肋平滑过渡连接，另一端为弧形端部，横筋上表面为一中心高向两侧平滑降低的弧形面，从与主肋连接的一端沿其延伸方向向另一端倾斜渐低。
进一步的，所述的主肋沿法兰盘的径向设置，各横筋由主肋向侧部延伸方向呈弧形，对应所在法兰盘圆周位置的曲率设置。
进一步的，每个主肋上的两侧横筋依次间隔交错设置，处于不同的圆周上，或者，同一主肋两侧的横筋一一对应每两个一组处于同一圆周上。
进一步的，两相邻主肋之间的两列横筋一一对应每两个一组处于同一圆周上，或者，依次间隔交错设置，处于不同的圆周上。
进一步的，每组主肋上的横筋沿主肋延伸方向由轴接部连接端向安装部连接端方向长度依次递增，横筋上表面的倾斜角度变小。
本发明另一种洗衣机内桶底法兰盘结构，法兰盘包括位于法兰盘中心的轴接部和位于轴接部外周与洗衣机内桶底固定连接的环形的安装部，安装部与轴接部之间设有多个连接部，连接部包括：主肋，由安装部延伸至轴接部，多个横筋，分别设于主肋两侧沿主肋延伸方向依次排列，加强肋，设于两相邻主肋之间，一端与安装部连接且另一端向轴接部自由延伸，多个加强筋，分别设于加强肋两侧沿加强肋延伸方向依次排列，相邻主肋的横筋与横筋之间及相邻主肋和加强肋的横筋和加强筋之间共同配合构成安装部和轴接部之间区域的过滤部。
进一步的，所述的主肋沿横筋延伸方向向两侧渐低，相邻主肋之间的两列横筋之间构成V形凹部，V形凹部底端为横筋间距形成的法兰盘上下通水的缺口，和/或所述的加强肋沿加强筋延伸方向向两侧渐低，相邻的每列横筋与每列加强筋之间具有间距形成的缝隙。
进一步的，所述主肋同一侧的两两相邻横筋之间设有间隙，和/或，加强肋同一侧的两两相邻横筋之间设有间隙。
进一步的，所述的主肋/加强肋上表面为一弧形表面，从中心向两侧圆弧过渡降低，与两侧的横筋/加强筋平滑过渡连接。
进一步的，所述的横筋/加强筋一端与主肋/加强肋平滑过渡连接，另一端为弧形端部，横筋/加强筋上表面为一中心高向两侧平滑降低的弧形面，从与主肋/加强肋连接的一端沿其延伸方向向另一端倾斜渐低。加强肋、加强筋的上表面分别和主肋、横筋的上表面一样为中心高向两侧渐低的弧形面，利于线屑滑动脱落、避免缠绕，造成堵塞。
进一步的，所述的主肋/加强肋沿法兰盘的径向设置，各横筋/加强筋由主肋/加强肋向侧部延伸方向呈弧形，对应所在法兰盘圆周位置的曲率设置。
进一步的，每个主肋/加强肋上的两侧横筋/加强筋依次间隔交错设置，处于不同的圆周上，或者，同一主肋/加强肋两侧的横筋/加强筋一一对应每两个一组处于同一圆周上。
进一步的，两相邻主肋之间的两列横筋一一对应每两个一组处于同一圆周上，或者，依 次间隔交错设置，处于不同的圆周上。
进一步的，相邻主肋和加强肋之间的横筋与加强筋一一对应，每两个一组处于同一圆周上，或者，依次间隔交错设置，处于不同的圆周上。
进一步的，所述的加强肋的长度小于主肋的长度，优选为小于主肋的一半长度；加强筋的长度对应与相邻主肋上横筋的长度变化对应改变，加强筋与相邻横筋之间配合形成过滤结构。
一般的变化为，主肋上的横筋长度自轴接部一端向另一端逐渐变大，至与加强肋自由端在同一圆周位置，横筋长度与加强肋上的加强筋长度互相配合变化以阻止设置在内外桶之间的物体进入内桶。
本发明上述两种法兰盘结构中的主肋、加强肋、横筋和加强筋的结构均利于排水时线屑通过，防止线屑缠绕在各部件上，减少了堵塞的可能性。
进一步的，上述两种法兰盘结构中的主肋或主肋和加强肋的数量分别为6-18个，但不限制在该范围内，该数量与法兰盘的尺寸和需求强度有关，法兰盘越大、强度要求越高则需要的主肋数量越多。
进一步的，安装部上设有与内桶底配合的螺钉安装孔，优选的还设有定位柱。
本发明具有上述法兰盘结构的洗衣机，具有清洁桶壁的功能，包括外桶和设于外桶内的内桶，内桶底部安装有所述的法兰盘，通过安装部和轴接部之间的多个连接部配合形成过滤部，该过滤部能够阻止洗涤过程内外桶之间的异物进入内桶。
采用上述技术方案后，本发明与现有技术相比具有以下有益效果。
由于内桶底部中空，本发明法兰盘连接部的各部件之间配合形成该中空位置的过滤装置，该过滤装置的作用是便于使不小心进入内桶的硬币、纽扣等杂物及线屑随排水内桶，又能防止其它需要设置在内外桶之间的物体例如清洗球在洗涤时随水流进入内桶；本发明法兰盘虽然是过滤内桶外部的异物进入内桶，但不影响排水时线屑的顺利排出，不会造成堵塞。
本发明法兰盘设计新颖、美观，采用一体成型结构，加工工艺简单，安装方便。
附图说明
图1是本发明所述的洗衣机内桶底和法兰盘安装结构断面示意图；
图2是本发明所述的法兰盘结构示意图；
图3是图2中的A部放大示意图；
图4是本发明所述的法兰盘另一结构示意图；

具体实施方式
下面结合附图对本发明的具体实施方式作进一步详细的描述。
如图1所示，波轮洗衣机包括外桶1和内桶2，内桶底4为一中空的环形结构，内桶底4下部安装有本发明所述的法兰盘5，以阻挡内外桶之间的异物洗涤时随水流运动进入内桶内，且不阻挡线屑的通过使其很容易排水时通过法兰盘进入内外桶之间，最后由外桶排水口排出。本发明所述的法兰盘与现有的法兰盘相比作出较大的改进，不再设有向外延伸的安装腿，而是整体呈一圆盘形状，圆盘上同圆心设有环形的中空区域，在该中空区域一体设有过滤结构(参阅图2和图4)。
如图2和图4所示，本发明所述法兰盘5包括位于法兰盘中心的轴接部6和位于轴接部6外周与洗衣机内桶底4固定连接的环形的安装部7，安装部6与轴接部7之间设有多个连接部8，连接部8包括由安装部7延伸至轴接部6的主肋81和分别设于主肋81两侧沿主肋81延伸方向依次排列的多个横筋82，多个连接部8配合构成安装部7和轴接部6之间区域的过滤部。安装部7上设有与内桶底4配合的螺钉安装孔9和定位柱10。
进一步的，所述的连接部8自主肋81沿横筋82延伸方向向两侧渐低，两两相邻连接部8之间构成V形凹部83，V形凹部83底端为两相邻主肋的横筋82之间间距形成的法兰盘上下通水的缺口84，内桶内的线屑、纽扣等杂物沿横筋82滑动由该缺口84通过进入外桶。
进一步的，所述任一主肋81同一侧的两两相邻横筋82之间设有间隙85，该间隙85结构利于水流的流动和线屑的通过。如图6所示，所述的主肋81上表面为一弧形表面，从中心向两侧圆弧过渡降低，与两侧的横筋82平滑过渡连接。所述的横筋82一端与主肋81平滑过渡连接，另一端为弧形端部(参阅图3)，横筋82上表面也为一中心高向两侧平滑降低的弧形面，从与主肋81连接的一端沿其延伸方向向另一端倾斜渐低。
优选的，所述的主肋81沿法兰盘的径向设置，各横筋82由主肋81向侧部延伸方向呈弧形，对应所在法兰盘圆周位置的曲率设置，横筋82位于不同半径的同心圆圆周上，其对应的弧形曲率不同。
实施例一
如图2和3所示，本实施例同一主肋81两侧的每列横筋82一一对应，每两个横筋为一组处于同一圆周上。或者，每个主肋81上的两侧横筋82依次间隔交错设置，处于不同的圆周上(图中未示出)。
实施例二
如图2和3所示，本实施例两相邻主肋81之间的两列横筋82依次间隔交错设置，处于不同的圆周。或者，如图4和5所示，两相邻主肋相邻两列的横筋82一一对应每两个一组处于同一圆周上。
实施例三
如图2和3所示，本实施例所述的连接部呈鱼骨结构，即主肋为椎骨，两侧横筋为横刺，每组主肋81上的横筋82沿主肋81延伸方向由轴接部6连接端向安装部7连接端方向长度依次递增，横筋82上表面的倾斜角度变小。
实施例四
如图4和5所示，本实施例在上述实施例三的基础上增加了悬梁结构，即于两两相邻主肋81之间设有加强肋86，加强肋86一端与安装部7连接另一端向轴接部6方向延伸，为自由端；加强肋86的两侧沿加强肋86延伸方向设有依次排列的多个加强筋87，每侧加强筋形成一列，每列加强筋87与相邻的主肋81上的一列横筋82之间具有间距形成的缝隙88，其结构与作用与两相邻主肋横筋之间的缺口84相同。
由于在两相邻主肋81之间增加加强肋86结构，加强肋86不完全连接安装部7和轴接部6，因此，加强肋86的长度小于主肋81的长度，优选为小于主肋81的一半长度；进而，加强筋87的长度对应与相邻主肋81上横筋82的长度变化对应改变，加强筋87与相邻横筋82之间配合形成过滤结构，同样阻挡内外桶之间异物的穿过，但能让内桶内的线屑在排水时通过。
一般的变化为，主肋81上的横筋82长度自轴接部6一端向另一端逐渐变大，至与加强肋87自由端在同一圆周位置，横筋82长度与加强肋86上的加强筋87长度互相配合以形成过滤部。
进一步的，加强肋86与安装部7连接的一端平滑过渡，另一端为光滑端部；加强肋86、加强筋87的上表面分别和主肋81、横筋82的上表面一样为中心高向两侧渐低的弧形面，利 于线屑滑动脱落、避免缠绕。
实施例五
如图4和5所示，与主肋81上横筋82的结构相同，加强肋上同一侧加强筋87之间也设有间隙89，作用与横筋之间的间隙85相同，两侧的加强筋87依次间隔交错设置，处于不同的圆周上，或者，一一对应每两个一组处于同一圆周上。
实施例六
如图4和5所示，加强肋86上同侧的一列加强筋87与相邻的主肋81上的一列横筋82一一对应，每两个一组，即一个加强筋和一个横筋为一组，处于同一圆周上；或者，依次间隔交错设置，处于不同的圆周上。
实施例七
本发明所述的洗衣机具有清洁桶壁的功能，即，在外桶1和内桶2之间设有随水流浮动碰撞摩擦桶壁的清洗颗粒3以清洁外桶内壁和内桶外壁(参阅图1)，利用上述的法兰盘结构可以阻挡清洗颗粒3进入内桶。但本发明所述的洗衣机并不限定在上述洗衣机范围内，安装有上述法兰盘结构的洗衣机均在本发明保护范围内。
本发明所述的主肋、加强肋、横筋和加强筋的结构均利于排水时线屑通过，防止线屑缠绕在各部件上，减少了堵塞的可能性。同时该结构能使硬币、钮扣等杂物由横筋、加强筋之间的间隙及缺口、缝隙内通过，减少了堵塞的可能性。
上述的主肋81和加强肋86数量分别为12个，但不限制在该范围内，该数量与法兰盘的尺寸和需求强度有关，法兰盘越大、强度要求越高则需要的主肋数量越多。
上述实施例中的实施方案可以进一步组合或者替换，且实施例仅仅是对本发明的优选实施例进行描述，并非对本发明的构思和范围进行限定，在不脱离本发明设计思想的前提下，本领域中专业技术人员对本发明的技术方案作出的各种变化和改进，均属于本发明的保护范围。
