Description

洗衣机 技术领域
本发明涉及一种洗衣机。
背景技术
例如专利文献1中公开了一种洗衣机，其具有：支承体，配置于能蓄水的外桶内，并以垂直的支承体旋转轴为中心自由旋转；以及球状的洗涤桶，由支承体以水平的洗涤桶旋转轴为中心自由旋转地支承，洗涤桶能向水平方向和垂直方向双方旋转。
专利文献1的洗衣机中，支承体由电机旋转驱动。在外桶的内侧设置有环状的洗涤桶转动导轨，在洗涤桶旋转轴设置有洗涤桶旋转轮。当洗涤桶通过电机的旋转而与支承体一起向水平方向旋转时，洗涤桶旋转轮在洗涤桶转动导轨上转动，洗涤桶也向垂直方向旋转。

发明内容
发明所要解决的问题
专利文献1的洗衣机也能不设置外桶而在支承体的内侧蓄水。即，也能使支承体作为能蓄水的外桶发挥作用。这种情况下，在作为支承体的外桶，设置有使水不会从形成于其上表面的洗涤物的投入口漏出地堵住投入口的外桶盖。
但是，在这样的结构中，在外桶盖相对于外桶只能单向打开的情况下，如果不确定使外桶的旋转停止的位置，则根据该停止位置，敞开的外桶盖可能会造成阻碍而不能顺利进行洗涤物向外桶内即洗涤桶内的投取。
另一方面，在采用使外桶停止在固定位置的结构的情况下，可能会使得驱动外桶的电机的控制变得复杂，或者使停止外桶所需的时间变长。
本发明是鉴于该问题而完成的发明，其目的在于，提供一种洗衣机，即使 不确定外桶的停止位置，也能良好地向外桶内投取洗涤物。
用于解决问题的方案
本发明的主要方式所涉及的洗衣机具备：外桶，以沿着垂直方向或相对于垂直方向倾斜的第一旋转轴为中心能旋转地配置于机壳内并能蓄水；内桶，以沿着水平方向或相对于水平方向倾斜的第二旋转轴为中心能旋转地配置于所述外桶内并容纳洗涤物；投入口，形成于所述外桶的上部，供洗涤物投入；外桶盖，覆盖所述投入口；以及连结机构部，以能使所述外桶盖相对于所述投入口至少向前侧、后侧、右侧以及左侧这周围四个方向敞开的方式连结所述外桶盖和所述外桶。
根据上述结构，无论外桶停止在什么位置，使用者都能将外桶盖向不影响往外桶内投取洗涤物的方向敞开。因此，可以顺畅地投取洗涤物。
本方案的洗衣机中，可以采用如下结构：所述连结机构部包括平行连杆机构部，所述平行连杆机构部以能使所述外桶盖相对于所述投入口向周围360°任意方向敞开的方式连结所述外桶盖和所述外桶。
根据上述结构，能将外桶盖相对于投入口向周围360°喜欢的方向敞开，可以更顺畅地投取洗涤物。
发明效果
根据本发明，能提供一种洗衣机，即使不确定外桶的停止位置，也能良好地向外桶内投取洗涤物。
本发明的效果以及意义通过以下所示的实施方式的说明会进一步明确。但是，以下的实施方式只是实施本发明时的一个例示，本发明不受以下的实施方式中记载的内容的任何限制。

在机壳10内，外桶20以相对于垂直方向稍微向前方倾斜的纵旋转轴R1为中心自由旋转地配置。在外桶20内，球状的内桶30以相对于水平方向稍微向前方倾斜的横旋转轴R2为中心自由旋转地配置。内桶30内容纳有洗涤物。内桶30为进行洗涤物的洗涤和脱水的洗涤脱水桶。需要说明的是，纵旋转轴R1与横旋转轴R2正交。此外，纵旋转轴R1相对于垂直方向的倾斜角度以及横旋转轴R2相对于水平方向的倾斜角度设定为例如10度至20度左右。需要说明的是，纵旋转轴R1相当于本发明的第一旋转轴，横旋转轴R2相当于本发明的第二旋转轴。
内桶30包括桶主体31和内盖32。桶主体31由例如不锈钢等耐腐蚀性优异的金属材料形成。在桶主体31，形成有许多脱水孔33。此外，在桶主体31，设置有圆形的内侧投入口34，内侧投入口34由内盖32开闭。内盖32由例如树脂形成，具有凸弯曲的形状。在内盖32的中央部，形成有可指握的把手部(未图示)。桶主体31的内侧投入口34的部分平坦，当内侧投入口34被内盖32关闭时，内桶30整体呈球体形状。
在内桶30的一侧即图2的状态下的后侧，用螺钉等安装有第一内桶轴35。此外，在内桶30的另一侧即图2的状态下的前侧，在隔着内桶30的中心与第一内桶轴35相反的一侧用螺钉等安装有第二内桶轴36。第一内桶轴35以及第二内桶轴36构成横旋转轴R2。
外桶20由例如树脂材料形成，并具有将内桶30覆盖到一半以上的球状。 在外桶20，以将其上部沿水平方向切断的方式形成有圆形的外侧投入口21。在外桶20，在隔着其中心对置的位置，形成有圆形的第一轴承装接口22以及第二轴承装接口23。
外桶20通过组合上外桶构件20a和下外桶构件20b而构成。上外桶构件20a与下外桶构件20b的分割面S穿过外桶20的中心部并且不与第一轴承装接口22以及第二轴承装接口23接触。即，外桶20以从比第二轴承装接口23更靠上的位置朝向比第一轴承装接口22更靠下的位置的方式，相对于横旋转轴R2被倾斜地分割。由此，在上外桶构件20a形成有第一轴承装接口22，在下外桶构件20b形成有第二轴承装接口23。
在上外桶构件20a的第一轴承装接口22装接有第一轴承部41。第一轴承部41包括圆筒状的轴承箱41a和容纳于轴承箱41a的滚动轴承41b，从外侧插入第一轴承装接口22，并通过螺钉等固定于外桶20。此外，在下外桶构件20b的第二轴承装接口23装接有第二轴承部42。第二轴承部42包括圆筒状的轴承箱42a和容纳于轴承箱42a的滚动轴承42b，从外侧插入第二轴承装接口23，并通过螺钉等固定于外桶20。
内桶30在通过上外桶构件20a与下外桶构件20b的组合来组装外桶20时容纳于外桶20内。此时，第一内桶轴35以及第二内桶轴36分别被插入第一轴承部41以及第二轴承部42。第一内桶轴35由第一轴承部41自由旋转地支承，第二内桶轴36由第二轴承部42自由旋转地支承。
外桶20的外侧投入口21由用例如树脂材料形成的外盖50可开闭地覆盖。外盖50穿过开口部11向机壳10的上方露出。外侧投入口21相当于本发明的投入口，外盖50相当于本发明的外桶盖。外盖50和外桶20通过平行连杆机构部60连结。平行连杆机构部60相当于本发明的连结机构部。关于平行连杆机构部60的详细结构在后面进行说明。
内桶30被内桶电机70旋转驱动。内桶电机70为例如外转子型电机，包括转子71和定子72。转子71固定于向外桶20的外侧突出的第一内桶轴35的顶端部，定子72固定于第一轴承部41的外表面。
在外桶20的底部中央，形成有圆板状的轴安装部24，在轴安装部24的侧面形成有排水口25。在轴安装部24，固定有具有规定形状的安装板80，外桶轴90经由安装板80固定于轴安装部24。外桶轴90构成纵旋转轴R1。此外，在安 装板80，固定有用于从外桶20内进行排水的排水装置100。排水装置100包括连接于排水口25的排水管101和设置于排水管101的排水阀102。在排水管101，连接有未图示的排水软管。
外桶轴90由外桶轴承部110自由旋转地支承。外桶轴承部110包括轴承箱111；以沿上下方向隔开规定间隔的方式配置于轴承箱111内的上滚动轴承112和下滚动轴承113。外桶轴承部110安装于配置在机壳10的底部的方形板状的外桶安装板120。外桶安装板120由安装于其四角的防振装置130弹性地支承。
外桶20被外桶电机140旋转驱动。外桶电机140为例如外转子型电机，包括转子141和定子142。转子141固定于从外桶轴承部110向下方突出的外桶轴90的顶端部，定子142固定于外桶轴承部110的下部。
接着，就根据平行连杆机构部60的外盖50的开闭构造进行说明。
图3的(a)是表示本实施方式的外盖50关闭状态的外桶20的上部的图，图3的(b)是表示本实施方式的外盖50打开状态的外桶20的上部的图。图4的(a)是本实施方式的连杆机构部200的立体图，图4的(b)是本实施方式的连杆机构部200的分解立体图。图5的(a)和(b)是用于对本实施方式的连杆机构部200的动作进行说明的图，分别是连杆机构部200的侧视图和俯视图。
在外盖50的中央部，形成有使用者开闭外盖50时所持的把手部51。此外，在外盖50的周缘部，由铁等磁体构成的四个吸附板52隔开大致90°的间隔安装于背侧。在外桶20的外侧投入口21的开口缘部，在外盖50关闭时与各个吸附板52匹配的位置，安装有磁铁26。吸附板52通过磁力吸附于磁铁26，由此保持外盖50对外侧投入口21的关闭状态。
平行连杆机构部60由以大致120°的间隔并列设置于外盖50与外桶20之间的三个连杆机构部200构成。
如图4的(a)和(b)所示，各个连杆机构部200由第一连杆210、第二连杆220、第三连杆230、第四连杆240、第一运动副(joint)250、第二运动副260、以及第三运动副270构成。这些第一连杆210、第二连杆220、第三连杆230、第四连杆240、第一运动副250、第二运动副260以及第三运动副270只要其强度适当，可以由金属或树脂中的任何材料形成。
第一连杆210和第二连杆220由第一运动副250连结。第一运动副250包 括设置于第一连杆210的旋转轴251和设置于第二连杆220并供旋转轴251插入的轴孔252。需要说明的是，可以在旋转轴251和轴孔252之间置入轴承。
第二连杆220和第三连杆230由第二运动副260连结。第三连杆230由两根杆231构成。第二运动副260是所谓的球节，包括形成于第三连杆230的各个杆231的端部的球状的球头(ring ball)261和设置于第二连杆220并与各个球头261球面接触的两个球头座262。
第三连杆230和第四连杆240由第三运动副270连结。第三运动副270与第二运动副260相同，为所谓的球节，包括形成于第三连杆230的各杆231的端部的球状的球头271和设置于第四连杆240并与各个球头271球面接触的两个球头座272。
如图5的(a)的箭头A所示，第二连杆220能相对于第一连杆210绕旋转轴251转动。此外，如图5的(a)的箭头B所示，第三连杆230能相对于第二连杆220向与两根杆231的排列方向垂直的面内方向转动。进而，如图5的(b)的箭头G所示，第三连杆230也能相对于第二连杆220，向与两根杆231的排列方向平行的面内方向转动。此处，因为第三连杆230由两根杆231构成，所以第四连杆240不能相对于第三连杆230向图5的(a)的箭头C以外的方向旋转运动。
但是，如图5的(a)的箭头D以及图5的(b)的箭头E、F所示，第四连杆240能向任意的三维方向平行移动。这意味着因为第四连杆240与外盖50一体活动，所以外盖50也能向任意的三维方向平行移动。
连杆机构部200的第一连杆210通过螺钉等固定于外桶20，第四连杆240通过螺钉等固定于外盖50。需要说明的是，第一连杆210也可以与外桶20一体形成，第四连杆240也可以与外盖50一体形成。
在向外桶20内的内桶30进行洗涤物的投取时，使用者为了将外侧投入口21敞开，抓住把手部51并使外盖50朝向外侧投入口21的周围移动。此时，由于外盖50通过平行连杆机构部60连结于外桶20，因而使用者能使外盖50相对于外侧投入口21向周围360°任意方向移动，并能使外盖50向任何方向敞开。
需要说明的是，为了在外盖50最大程度敞开时，具有至少外侧投入口21的一半以上，理想的是全部敞开的可动区域，平行连杆机构部60配置有三个连杆机构部200。
当洗涤物向外桶20内的投取结束时，使用者将敞开的外盖50复位并关闭外侧投入口21。此时，外盖50返回与敞开前相同的位置。
全自动洗衣机1中，进行各种运转模式的洗涤运转。洗涤运转中，按顺序执行洗涤过程、中间脱水过程、漂洗过程以及最终脱水过程。
洗涤过程以及漂洗过程中，外桶20内蓄水至规定水位。规定水位为内桶30浸在水中的位置，可以设定为低于内桶30的中心位置即横旋转轴R2的位置的位置。需要说明的是，洗涤过程中，蓄积的水中含有洗涤剂。
在外桶20内蓄有水的状态下，外桶电机140以单向旋转的方式被驱动，外桶20以纵旋转轴R1为中心单向旋转，内桶30与外桶20一体地旋转。此外，内桶电机70以向正方向以及反方向交替旋转的方式被驱动，内桶30有别于外桶20的动作，以横旋转轴R2为中心向正方向以及反方向交替旋转。
通过外桶20的旋转而在外桶20内产生水流。此外，在产生了水流的外桶20内，通过使内桶30横向旋转同时纵向进行反转旋转，在内桶30内被搅拌的洗涤物进行复杂的运动。由此，外桶20内产生的水流和洗涤物的复杂运动相辅相成，洗涤物被良好地清洗或者漂洗。
此外，在内桶30为球状的情况下，因为横旋转轴R2的方向上的圆周面也是圆弧状，所以位于内桶30内的两端部分的洗涤物变得容易得到高于水面的位置，两端部分的洗涤物难以浸入水中。但是，在本实施方式中，因为外桶20横向旋转，所以外周侧的水通过离心力上升，两端部分的洗涤物也变得容易浸水。
需要说明的是，也可以通过使外桶电机140向正反方向反转旋转，使得外桶20向正方向和反方向交替旋转。进而，也可以使外桶电机140即外桶20的旋转速度变化，使外桶20内的水流的速度变化。
中间脱水过程以及最终脱水过程中，在从外桶20内进行排水之后，在外桶20停止的状态下，内桶30单向高速垂直旋转。洗涤物通过内桶30所产生的离心力的作用而被脱水。
本实施方式的全自动洗衣机1中，虽然不仅内桶30，外桶20也进行旋转，但是外桶20停止的位置不确定。不过，因为无论外桶20在什么位置停止，外盖50都可以相对于外侧投入口21向周围360°任意方向敞开，所以使用者能使外盖50向不影响往外桶20内投取洗涤物的合适方向敞开。因此，可以顺畅地投取洗涤物。
以上，对本发明的实施方式进行了说明，但本发明不受上述实施方式的任何限制，另外，本发明的实施方式也可以进行上述以外的各种变更。
例如，上述实施方式中，外盖50和外桶20由平行连杆机构部60连结，由此，外盖50能相对于外侧投入口21向周围360°任意方向敞开。但是，外盖50只要能相对于外侧投入口21向至少前侧、后侧、右侧以及左侧这周围四个方向敞开即可，如果能实现这样敞开外盖50的话，也可以使用平行连杆机构部60之外的连结机构部。
此外，上述实施方式中，连杆机构部200的第二运动副260以及第三运动副270采用所谓的球节。但是，第二运动副260以及第三运动副270也可以采用所谓的万向节。
进而，上述实施方式中，外桶20以相对于垂直方向倾斜的纵旋转轴R1为中心进行旋转，内桶30以相对于水平方向倾斜的横旋转轴R2为中心进行旋转。但是，也可以采用外桶20以沿着垂直方向的纵旋转轴为中心进行旋转的结构。同样，也可以采用内桶30以沿着水平方向的横旋转轴为中心进行旋转的结构。
进而，上述实施方式中，虽然外桶电机140以及内桶电机70采用外转子型电机，但是也可以采用内转子型电机。
进而，上述实施方式中，虽然例示出了全自动洗衣机1，但是本发明也可以用于除了洗涤功能之外还具有烘干功能的全自动洗干一体机。
此外，本发明的实施方式在权利要求书所展现的技术思想范围内，能适当地进行各种变更。
