Description

洗衣机外筒及洗衣机 技术领域
本公开涉及洗衣机技术领域，例如涉及一种洗衣机外筒及具有该洗衣机外筒的洗衣机。
背景技术
如图1所示，洗衣机外筒1′的外形普遍为圆形，外筒1′一般通过外筒筒体上方的两侧挂簧2′悬挂在洗衣机壳体3′的两侧，并通过外筒筒体下方的两根减震器4′支撑并降低振动振幅，共同稳定外筒1′筒体。在不增加外筒直径的情况下外筒限制了内筒的直径大小，也就限制了洗衣机的洗涤容量。在壳体结构与尺寸不改变的情况下，增大外筒的直径会减少壳体与外筒之间的空间，可能造成外筒在工作过程中碰撞壳体造成壳体变形等问题，因此，洗衣机在壳体空间固定的情况下，为避免洗衣机工作过程中外筒碰撞和干涉壳体的两侧板，洗衣机外筒筒体与壳体必须保持一定的空间，相关技术普遍采取的措施是减小外筒直径，这样会减少内筒的容量，从而约束了洗衣机洗涤容量的提升。
基于以上描述，需要一种新的洗衣机外筒，以解决洗衣机在壳体空间固定的情况下，因增大外筒直径而使得工作过程中外筒碰撞壳体造成壳体变形的问题，或为避免洗衣机工作过程中外筒碰撞壳体而减小外筒直径，造成洗衣机洗涤容量减小等问题。
发明内容
本公开提出一种洗衣机外筒，该洗衣机外筒在洗衣机壳体不变的情况下，充分利用了洗衣机的内部空间，增大了直径，提高了洗衣机的洗涤容量，同时 有效避免了洗衣机工作过程中外筒与壳体发生碰撞和干涉的问题。
为达此目的，本公开采用以下技术方案：
本公开提供了一种洗衣机外筒，所述外筒两相对的侧壁设置为非圆面，避免与壳体侧板发生碰撞。
作为一种洗衣机外筒的可选方案，所述非圆面为平面或由不同曲率的弧形曲面所拼接而成的曲面。
作为一种洗衣机外筒的可选方案，所述外筒的外侧壁和外底壁上设置有网状加强筋。此网状加强筋结构的设计在不增加外筒的壁厚并且节省了原材料的同时，可以提高外筒的整体强度，节省制造原材料。
作为一种洗衣机外筒的可选方案，所述外筒的内底壁为与内筒后法兰形状相匹配的光滑弧面。该光滑弧面设计可以减少外筒筒内污垢的附着，同时，可以合理节省装配空间，提升内筒容积。
作为一种洗衣机外筒的可选方案，所述外筒的外周面上设置有至少两个定位孔，所述定位孔的轴线方向与所述外筒的轴线方向相同，所述定位孔用于穿设定位支撑杆，以通过所述定位支撑杆将所述外筒固定在壳体上。该洗衣机外筒在运输过程中采用上述结构的运输固定装置来支撑并固定筒体，可以对外筒筒体的上下位移进行限定，有效提升外筒的包装运输装配结构，提高运输装配的安全可靠性。
作为一种洗衣机外筒的可选方案，所述外筒的外周面上设置有与所述定位孔数量相匹配的加强筋，每条加强筋设置在与每条加强筋相对应的定位孔四周。
作为一种洗衣机外筒的可选方案，所述外筒的端部设置有至少三个螺钉柱，所述螺钉柱用于通过螺栓将外筒固定在洗衣机壳体上。
作为一种洗衣机外筒的可选方案，所述外筒的端部设置有与所述螺钉柱数量相匹配的导向加强筋，每条导向加强筋设置在与每条导向加强筋相对应的螺钉柱四周，所述导向加强筋用于加强螺钉柱的结构强度并防止螺栓错位连接螺钉柱。
作为一种洗衣机外筒的可选方案，所述外筒的筒体上设置有用于固定通气管的卡槽。该卡槽可以卡住洗衣机压力开关的通气管，有效减少装配工时，提高装配效率，同时，可以避免洗衣机在工作状态下壳体振动对通气管的磨损。
本公开还提出一种洗衣机，该洗衣机具有本公开任一实施例提供的洗衣机外筒。
本公开的有益效果为：
(1)本公开提供了一种洗衣机外筒，该洗衣机外筒两相对的侧壁设置为非圆面，避免与壳体侧板发生碰撞。在保证洗衣机壳体不变的情况下，充分利用了洗衣机的内部空间，增大外筒直径，有效避免了洗衣机工作过程中外筒与壳体发生碰撞和干涉，提高了洗衣机的洗涤容量。
(2)外筒的外侧壁和外底壁上设置有网状加强筋。可选的，设置在外筒外侧壁上的网状加强筋由垂直于筒体轴线的径向环加强筋和平行于筒体轴线的轴向加强筋固定连接而成；设置在外筒外底壁上的网状加强筋由垂直于筒体轴线的环形周向加强筋和垂直于筒体轴线的发射状径向加强筋固定连接而成。网状加强筋的设置在不增加外筒的壁厚并且节省了原材料的同时，提高了整个外筒筒体的结构强度。
(3)外筒的内底壁为与内筒后法兰形状相匹配的光滑弧面，可以有效减少外筒内污垢的附着，清洁卫生，同时合理的节省了装配空间，提升了内筒容积。
(4)外筒的外周面上设置有至少两个定位孔，定位孔的轴线方向与外筒的轴线方向相同，定位孔用于穿设定位支撑杆以通过定位支撑杆将外筒固定在壳体上。在洗衣机的运输过程中，由于外筒被定位支撑杆牢固固定在洗衣机中，外筒不会因振动而上下运动，从而有效避免外筒因振动而与洗衣机中的部件发生碰撞，提高洗衣机在运输过程中的可靠性。
(5)外筒的外周面上设置有与定位孔数量相匹配的加强筋，每条加强筋设置在与每条加强筋相对应的定位孔四周。加强筋的设置能够有效避免定位支撑杆在穿过定位孔对外筒进行定位时对定位孔施力的冲击和损坏，增强定位孔的结构强度。
(6)外筒的端部设置有至少三个螺钉柱，螺钉柱用于通过螺栓将外筒固定在洗衣机壳体上。在洗衣机的搬运过程中，由于外筒的轴线方向被螺栓定位，外筒不会因为振动而沿轴向方向移动，从而有效避免外筒因振动而与洗衣机中的部件发生碰撞，更有利于提高洗衣机在运输过程中的可靠性。
(7)外筒的端部设置有与螺钉柱数量相匹配的导向加强筋，每条导向加强筋设置在与每条导向加强筋相对应的螺钉柱四周，导向加强筋的设置不仅可以有效防止螺栓错位连接螺钉柱，起到导向作用，而且还可以加强螺钉柱的结构强度。
(8)外筒的筒体上设置有用于固定通气管的卡槽，采用无螺钉设计，可以减少装配工时，同时有效避免洗衣机在工作状态下振动对通气管的磨损，延长通气管的使用寿命。
(9)本公开还提供了一种洗衣机，该洗衣机具有如以上任一项所述的洗衣机外筒，该洗衣机可以具有以上任一项洗衣机外筒带来的有益效果。

具体实施方式
下面将结合附图对本公开实施例的技术方案作进一步的详细描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
实施例一
图2是本实施例一提供的洗衣机外筒的结构示意图。如图2所示，本实施例洗衣机外筒1两相对的侧壁设置为非圆面，避免与壳体2侧板21发生碰撞，即洗衣机外筒1靠近洗衣机壳体2两侧侧板21的筒壁设置为非圆面，避免与壳体侧板21发生碰撞。
在本实施例中，非圆面可选为平面，该平面可为与壳体2的侧板21之间具有一定预留间隙且具有一定长度的直边20。可选的，如图2所示，本实施例的直边20与壳体2的侧板21之间预留了15mm的间隙(即图2中的L1)，直边20的长度L2为230mm。直边20与壳体2的侧板21之间的预留间隙L1和直边20的长度L2可根据外筒1的运动轨迹情况进行设计，可以满足避免外筒1在振动过程中碰撞和干涉壳体侧板21的要求即可。
其中，在洗衣机壳体2及预留空隙L1不变的情况下，为充分利用洗衣机的 内部空间，而增大外筒1直径，并根据洗衣机内筒的运动轨迹及多次试验得出结论：外筒1的直径越大，直边20的长度L2也应越大。
其中，外筒1除靠近壳体2两侧侧板21的侧壁部分外的其他筒壁部分与相关技术中洗衣机外筒筒壁的形状相同，均为具有相同曲率的圆面。
本实施例提供的洗衣机外筒，在保证洗衣机壳体不变的情况下，充分利用了洗衣机的内部空间，增大外筒直径，有效避免了洗衣机工作过程中外筒与壳体发生碰撞和干涉，提高了洗衣机的洗涤容量。
实施例二
图3为本实施例二提供的一种洗衣机外筒的结构示意图，如图3所示，该实施例所述的洗衣机外筒的结构与实施例一所述的洗衣机外筒的结构的区别之处在于：
洗衣机外筒1两相对的侧壁设置为非圆面，可选的，非圆面为由不同曲率的弧形曲面所拼接而成的曲面，在本实施例中，可选的，不同曲率的弧形曲面均为向壳体2的侧板21方向凸起的弧面。
其中，非圆面之所以设计成上述形状而并非由不同曲率且向外筒1中心凹陷的弧面所拼接而成的曲面，主要考虑两方面的原因：一方面是在增大外筒1和内筒直径的情况下，有效避免外筒1在振动过程中与壳体侧板21发生碰撞和干涉；另一方面是在增大外筒1和内筒直径的情况下，有效避免外筒1在振动过程中与内筒发生碰撞和干涉。基于以上所述，非圆面无法设计成由不同曲率且向外筒1中心凹陷的弧面所拼接而成的曲面，仅能设计成由不同曲率且向壳体2侧板21方向凸起的弧面所拼接而成的曲面。
在本实施例中，非圆面可选为由两个不同曲率且向壳体2侧板21方向凸起 的弧面所拼接而成的曲面。两个弧面分别为图3中由虚线分隔开的第一弧面9(图3中上短实线与中短虚线之间的弧面)和第二弧面10(图3中的下短实线与中短虚线之间的弧面)。上述两个弧面的曲率大小可根据外筒1的运动轨迹情况进行选择，能够实现避免外筒1在振动过程中碰撞和干涉壳体侧板21的效果即可。
本实施例外筒1的其他筒壁部分结构与实施例一所述的外筒1其他筒壁部分的结构相似或相同，故在此不再赘述。
可选的，为了提高具有如上所述洗衣机外筒1的洗衣机(干衣机或洗干一体机)的冷凝效果，如图3和图4所示，洗衣机还设置有水冷式冷凝器，所述水冷式冷凝器包括设置在外筒1底端的冷凝器接口121，在冷凝器接口121处设置有V型导流槽122，能够方便烘干的冷凝水流出。
本实施例提供的洗衣机外筒，在保证洗衣机壳体不变的情况下，充分利用了洗衣机的内部空间，增大外筒直径，有效避免了洗衣机工作过程中外筒与壳体发生碰撞和干涉，提高了洗衣机的洗涤容量。
实施例三
图5为本实施例三提供的一种洗衣机外筒的结构示意图，如图5所示，在如实施例一所述的洗衣机外筒结构(即靠近洗衣机壳体2两侧侧板的筒壁设置为平面，避免与壳体侧板21发生碰撞)的基础上，该实施例的外筒1的外侧壁11和外底壁12上设置有网状加强筋。
在本实施例中，可选的，设置在外筒1的外侧壁11上的网状加强筋由多条垂直于筒体轴线的径向环加强筋5和多条平行于筒体轴线的轴向加强筋6固定连接而成。设置在外筒1外底壁12上的网状加强筋由多条垂直于筒体轴线的环 形轴向加强筋7和多条平行于筒体轴线的发射状径向加强筋8固定连接而成。相邻两条径向环加强筋5之间的间距、相邻两条轴向加强筋6之间的间距、相邻两条环形轴向加强筋7之间的间距和相邻两条发射状径向加强筋8之间的间距大小可从生产成本和结构强度等方面进行考虑设计。
本实施例提供的洗衣机外筒，在洗衣机外筒的外侧壁11和外底壁12上分别设置的上述网状加强筋，在不增加外筒的壁厚并且节省了原材料的同时，提高了整个外筒筒体的结构强度。
实施例四
相关技术中的洗衣机外筒的内底壁普遍采用平底面设计，但是平底面的结构不仅容易使得外筒内附着大量的污垢，不便于清洗，而且需要预留出一定的内筒装配空间，装配空间占用面积大，内筒的容积也相对较小。
为了解决上述问题，本实施例四提供了一种新的洗衣机外筒结构，如图6所示，本实施例的洗衣机外筒1的内底壁13采用向外筒底壁方向凹陷的光滑弧面设计，且光滑弧面与内筒的后法兰形状相匹配。也就是说，光滑弧面的曲率大小由内筒的后法兰形状决定。
本实施例提供的洗衣机外筒的内底壁设置为凹陷的光滑弧面结构，既能够保证内筒的正常转动运行，而且有效减少了外筒内污垢的附着，清洁卫生，同时合理的节省了装配空间，提升了内筒容积。
实施例五
图7至图9为本实施例五提供的一种洗衣机外筒的结构示意图，图10为本实施例的洗衣机的结构示意图。如图7至图10所示，可选的，本公开的洗衣机 外筒1的外周面上设置有至少两个定位孔，定位孔的轴线方向与外筒1的轴线方向相同，定位孔用于穿设定位支撑杆3以通过定位支撑杆3将外筒1固定在洗衣机壳体2上。
在本实施例中，可选的，外筒1靠近外筒前后两端的外周面(外筒1的前法兰和后法兰)上分别设置有并列排布的两个定位孔(图7未示出外筒1前端的两个定位孔)，且前后端的定位孔位置一一对应，组成两组定位孔(4个定位孔)，位于同一端的两个定位孔之间形成的圆周角度在60度到110度的范围内。可选的，两组定位孔分别为一组第一定位孔91和一组第二定位孔92，一组第一定位孔91和一组第二定位孔92中可分别穿设一根定位支撑杆3，洗衣机壳体2上开设有与两组定位孔一一对应的两组第一安装孔18，将定位支撑杆3穿过第一安装孔18和定位孔，实现通过定位支撑杆3将外筒1牢固定位在壳体2上。在洗衣机的运输过程中，由于外筒1被定位支撑杆3牢固固定在洗衣机中，外筒1不会因振动而上下运动，从而有效避免外筒1因振动而与洗衣机中的部件发生碰撞，提高洗衣机在运输过程中的可靠性。
可选的，为了方便在外筒1上设置定位孔，并有效的对定位孔的结构强度进行增强，外筒1的外周面上设置有与定位孔数量相匹配的加强筋15，在本实施例中，外筒1靠近外筒前后两端的外周面上分别设置有两条加强筋15，也就是说加强筋15共有两组(包括4条加强筋15)，每个第一定位孔91设置在一条加强筋15上，每个第二定位孔92设置在一条加强筋15上。如图8所示，每条加强筋15包括一条环形加强筋151、多条径向加强筋152和一圈封闭环筋153，环形加强筋151和多条径向加强筋152均垂直于外筒1侧壁设置，多条径向加强筋152呈发射状设置在环形加强筋151与外筒1侧壁围成的空间中，每条径向加强筋152的第一端均与环形加强筋151固定连接，第二端与形成定位 孔的封闭环筋153固定连接。加强筋15的设置有效避免了定位支撑杆3在穿过定位孔对外筒1进行定位时对定位孔施力的冲击和损坏，从而增强了定位孔的结构强度。
可选的，如图7-图10所示，为了有效防止外筒1因振动而沿轴线方向移动，本公开的洗衣机外筒1的后端部设置有至少三个螺钉柱14，螺钉柱14用于通过螺栓16将外筒1固定在洗衣机壳体2上。
在本实施例中，可选的，洗衣机外筒1的筒底端部均布有四个螺钉柱14，四个螺钉柱14对称设置，其中两个螺钉柱14设置在筒底上方，另两个螺钉柱14设置在筒底下方，位于筒底下方的两个螺钉柱14分别靠近第一定位孔91和第二定位孔92设置。洗衣机壳体2上开设有与四个螺钉柱14一一对应的第二安装孔19，四个螺钉柱14用于与穿设在第二安装孔19中的螺栓16进行螺接。每个螺栓16能够穿过一第二安装孔19与一螺钉柱14螺接，实现通过螺栓16对外筒1的轴线方向进行定位。在洗衣机的搬运过程中，由于外筒1的轴线方向被螺栓16定位，外筒1不会因为振动而沿轴向方向移动，从而有效避免外筒1因振动而与洗衣机中的部件发生碰撞，更有利于提高洗衣机在运输过程中的可靠性。
可选的，为了方便在外筒1上设置螺钉柱14，并有效的对螺钉柱14的结构强度进行增强，外筒1的筒底端部设置有与螺钉柱14数量相匹配的导向加强筋17，在本实施例中，外筒1的筒底端部设置有四条导向加强筋17，每条导向加强筋17设置在与每条导向加强筋17相对应的螺钉柱14四周。
在本实施例中，可选的，如图9所示，每条导向加强筋17包括多条径向导向加强筋171和一圈封闭导向环筋172，多条径向导向加强筋171呈发射状设置且均垂直于外筒1筒底。径向导向加强筋171的第一端与形成螺钉柱14的封闭 导向环筋172固定连接，径向导向加强筋171的第二端具有凸出于螺钉柱14上端面的凸起结构1711，该凸起结构1711的内侧为一斜面1712，该斜面1712用于螺栓16插入螺钉柱14时的导向。可选的，上述斜面1712的底端与螺钉柱14中心线的距离小于斜面1712的顶端与螺钉柱14中心线的距离，也就是说，所有径向导向加强筋171的凸起结构1711的斜面1712共同形成上宽下窄的圆锥体空腔，该圆锥体空腔可用于对包装螺栓组件的固定支撑件161进行限位。如此，上述结构的导向加强筋17不仅可以有效防止螺栓16错位连接螺钉柱14，起到导向作用，而且还可以加强螺钉柱14的结构强度。
为了更方便快捷的装配螺栓16，可通过包装螺栓组件对螺栓16进行装配。如图11和图12所示，所述包装螺栓组件包括固定支撑件161、固定套管162、垫片163和缓冲垫164，通过螺栓16将垫片163、缓冲垫164、固定套管162和固定支撑件161固定。在螺栓16装配包装螺栓组件过程中，螺栓16依次穿过垫片163、缓冲垫164、固定套管162、壳体2上的第二安装孔19、固定支撑件161和螺钉柱14螺接。垫片163、缓冲垫164、固定套管162处于洗衣机壳体2的外侧，固定支撑件161则处于壳体2与外筒1之间的空间内，且固定支撑件161端部至少部分限位在外筒1上设置的导向加强筋17的圆锥体空腔中。如此，实现对外筒1在径向方向上例如在轴向方向上的牢固固定。
可选的，为了方便拆卸装配的螺栓16，固定套管162上设置有对称设置的两个拉环扣1621，通过拉动两个拉环扣1621可方便快捷的拆除螺栓16及包装螺栓组件，节省了拆卸工时，提高了拆卸效率。
本实施例中的外筒1不局限于设置有两组定位孔，还可以设置有三组定位孔，与定位孔相匹配设置的加强筋15的数量也相应为三组，位于外筒1同一端的三个定位孔的圆心形成一稳固的三角形，洗衣机外壳2上开设有与三组定位 孔一一对应的三组第一安装孔18，通过三根定位支撑杆3穿设上述的三组第一安装孔18和三组定位孔，也能够实现对外筒1的径向方向进行定位。
本实施例中的外筒1不局限于设置有四个螺钉柱14，还可以设置有三个螺钉柱14，与螺钉柱14相匹配设置的导向加强筋17的数量也相应为三条，三个螺钉柱14的圆心形成一稳固的三角形，洗衣机外壳2上开设有与三个螺钉柱14一一对应的第二安装孔19，通过三根螺栓16穿设上述的三个第二安装孔19和三个螺钉柱14，也能够实现对外筒1的轴向方向进行定位。
实施例六
图13和图14为本实施例六提供的一种洗衣机外筒的结构示意图，如图13和图14所示，本实施例的洗衣机外筒1的筒体上设置有用于固定通气管的卡槽4，在本实施例中，卡槽4可选为卡勾，卡勾的开口大小与通气管的直径大小相匹配。本实施例的卡槽4采用无螺钉设计，减少了装配工时，有效避免了洗衣机在工作状态下壳体2振动对通气管的磨损，延长了通气管的使用寿命。
另外，洗衣机外筒1采用至少三根减震器进行支撑，在本实施例中，可选的，采用对称设置的四根减震器对外筒1进行支撑稳固。可选的，每两根减震器分别设置在外筒1的两侧，每一侧相对前后分别设置有一根减震器，如此，在四根减震器的支撑作用下，外筒1筒体受力均匀，大大减小了外筒1的振动振幅，提高了外筒1的振动稳定性。
实施例七
本实施例七提出一种具有如本实施例一至六任一实施例所述的洗衣机外筒的洗衣机，该洗衣机可以具有上述任一实施例提供的洗衣机外筒带来的有益效 果。
注意，本领域技术人员会理解，本公开不限于这里所述的特定实施例，对本领域技术人员来说能够进行各种变化、重新调整和替代而不会脱离本公开的保护范围。因此，虽然通过以上实施例对本公开进行了较为详细的说明，但是本公开不仅仅限于以上实施例。
