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，其中，被弹性支承于外箱内的水桶的上表面的开口由中央具有开口部的桶罩闭塞，开口部由内盖来开闭。在专利文献1的洗衣机中，在内盖设置有被转动操作的把手。把手上设置有具有爪部的挂钩构件。当内盖被闭塞时，挂钩构件的爪部会与设置于桶罩侧的卡定构件的爪部卡合，内盖保持闭塞状态。
这样，在采用通过爪部使内盖保持闭塞状态的构造的情况下，内盖敞开时爪部的构造会露出到外部，用户看到敞开的内盖时不一定会觉得美观。
因此，为了使内盖美观，可以考虑采用一种使用磁铁并通过磁铁的吸附力来使内盖保持闭塞状态的构造。
例如，专利文献2中公开了在洗衣机中为了保持洗涤剂供给装置的盖的闭塞而使用磁铁。
在像专利文献2那样为了保持洗涤剂供给装置的盖的闭塞而使用磁铁的情况下，由于其吸附力可以较弱，因此用户容易顺利进行盖的开闭操作。
另一方面，容易因脱水时可能产生的水桶的上下振动、清洗时等情况下可能产生的洗涤物对内盖的撞击，而对内盖施加向敞开方向的较大的力。因此，在为了保持内盖的闭塞而使用磁铁的情况下，要求较强的吸附力。由此，这种情况下，用户的开闭操作恐怕不容易进行。

发明内容
发明所要解决的问题
因此，本发明的目的在于提供一种洗衣机，其在通过使用了磁铁的构造来保持覆盖外桶上表面的开口部的外桶盖的闭塞的情况下，用户能容易地进行外桶盖的开闭操作。
用于解决问题的方案
本发明的主要方案的洗衣机具备：外桶，弹性地支承于机壳内；洗涤脱水桶，可旋转地配置于所述外桶内，收容洗涤物；以及外桶盖，将设置于所述外桶的上表面的开口部闭塞。在此，所述外桶盖在其一端部具有第一旋转轴，通过以所述第一旋转轴为中心相对于所述外桶转动来进行开闭，在其另一端部具有能以与所述第一旋转轴平行的第二旋转轴为中心旋转的把手。所述把手包括：第一配置面，在所述外桶盖将所述开口部闭塞的状态下与所述外桶的上表面对置；第一吸附面，配置在所述第一配置面内；以及拉把部，以在所述第一旋转轴和所述第二旋转轴的排列方向上远离所述第一吸附面的方式设置，供用户的手勾住。所述外桶的上表面包括：第二配置面，与所述第一配置面对应；以及第二吸附面，配置在所述第二配置面内，在所述外桶盖将所述开口部的闭塞状态下与所述第一吸附面接触。所述第一吸附面和所述第二吸附面当中，一方的面产生磁铁的磁力，另一方的面通过所产生的磁力被拉向所述一方的面。当在所述外桶盖将所述开口部闭塞的状态下抬起所述拉把部时，在隔着所述第一配置面的所述第一吸附面与所述拉把部相反侧的位置形成有支点，所述第一配置面以该支点为中心转动，所述第一吸附面脱离所述第二吸附面。
根据上述的结构，通过以拉把部为力点并以第一吸附面中与第二吸附面的接触区域为作用点的杠杆原理，能将第一吸附面容易地从第二吸附面拉开。由此，用户能容易地进行外桶盖的开闭操作。
在本方案的洗衣机中，可以采用如下结构：所述第二配置面构成为高于所 述外桶的上表面，所述第一配置面在与所述拉把部的方向相反的方向上比所述第二配置面更突出，在突出的面部分与所述外桶的上表面之间形成有空间。
根据上述的结构，由于能在第一配置面靠近第一吸附面的部分，而不是在第一配置面的端部形成支点，因此，能缩短从支点到作为作用点的第一吸附面的接触区域的距离。由此，容易对第一吸附面的接触区域施加向上的大的力，能更容易地将第一吸附面从第二吸附面拉开。
在采用上述结构的情况下，可以进一步在所述第一配置面，在相对于所述第一吸附面与所述拉把部相反的一侧，设置向所述外桶的上表面侧突出并作为所述支点的突起部。这种情况下，在所述外桶的上表面，设置有以从所述第二配置面连续的方式向所述空间侧下降并与所述突起部相接的倾斜面。
当通过抬起拉把部转动把手时，第二旋转轴会随之向上方移动，外桶盖以第一旋转轴为中心转动而稍稍敞开。通过打开外桶盖，对把手施加将把手向水平方向拉的力。在上述的结构中，当把手向水平方向被拉动时，倾斜面通过突起部被推向水平方向，这个水平方向的力会被转换为朝向上方的力而作用于突起部。由此，突起部会沿着倾斜面上升，与把手的转动同时上升，因此，能更容易地将第一吸附面从第二吸附面拉开。
在采用上述结构的情况下，可以进一步采用所述突起部具有与所述倾斜面平行的面的结构。
当采用这种结构时，由于突起部的平行的面与倾斜面大体上进行面接触，因此，能通过突起部顺利地将倾斜面向后方推，能将通过倾斜面被转换后的向上方的力充分地施加于突起部。由此，能使把手容易上升，能更加容易地将第一吸附面从第二吸附面拉开。
在采用上述结构的情况下，进而，所述突起部的顶端部可以具有圆弧形状。
在采用这样的结构的情况下，当把手继续转动时，顶端部不容易卡在倾斜面，能顺利地转动把手。
在本方案的洗衣机中，所述一方的面可以由所述磁铁的表面构成。这种情况下，所述另一方的面由磁性体的表面构成。
根据上述的结构，能强力吸附第一吸附面与第二吸附面，能通过外桶盖可 靠地闭塞开口部。

根据本发明，在通过使用了磁铁的构造来保持覆盖外桶上表面的开口部的外桶盖的闭塞的情况下，用户能容易地进行外桶盖的开闭操作。

具体实施方式
以下，参照附图，对本发明的实施方式进行说明。
图1是本实施方式的全自动洗衣干衣机1的侧剖图。图2是本实施方式的全自动洗衣干衣机1的上部的后视立体图。
全自动洗衣干衣机1具备构成外观的机壳10。机壳10包括：方形筒状的机身部11，上下表面敞开；上面板12，覆盖机身部11的上表面；以及脚台13，支承机身部11。在上面板12形成有用于投入洗涤物的外侧投入口14。外侧投入口14由开闭自如的上盖15覆盖。
在机壳10内，外桶20通过具有防振装置的四根吊棒21弹性地悬吊支承。外桶20包括上表面敞开的大致圆筒状的外桶主体22、和通过覆盖外桶主体22的上表面而构成外桶20的上表面的外桶罩100。在外桶20的上表面即外桶罩100，在与外侧投入口14对应的位置形成有用于投入洗涤物的内侧投入口101。内侧投入口101由外桶盖23可开闭地覆盖。
在外桶20内，配置有上表面敞开的大致圆筒状的洗涤脱水桶24。在洗涤脱水桶24的内周面，遍及整周地形成有许多脱水孔24a。在洗涤脱水桶24的上部设置有平衡环25。在洗涤脱水桶24的底部配置有波轮26。在波轮26的表面，呈放射状地设置有多个叶片26a。
在外桶20的外底部配置有产生驱动洗涤脱水桶24以及波轮26的转矩的驱动单元30。驱动单元30包括驱动电机31和传递机构部32。传递机构部32具有离合器机构，通过该离合器机构的切换操作，在洗涤过程以及漂洗过程中将 驱动电机31的转矩仅传递给波轮26而仅使波轮26旋转，并在脱水过程中将驱动电机31的转矩传递给波轮26以及洗涤脱水桶24而使波轮26以及洗涤脱水桶24一体旋转。
在外桶20的外底部形成有排水口部20a。在排水口部20a设置有排水阀40。排水阀40与排水软管41连接。当排水阀40打开时，蓄于洗涤脱水桶24以及外桶20的水通过排水软管41向机体外排出。
在机壳10内的后部，在外桶20的上方配置有烘干装置50和供水装置60。烘干装置50和供水装置60安装于配置在机身部11的上表面后部的固定板16，被上面板12覆盖。
烘干装置50将收容在洗涤脱水桶24内的洗涤物烘干。烘干装置50包括加热器和配置有鼓风扇的循环风路50a，循环风路50a通过吸气管道71以及排气管道72与外桶20的内部连接。吸气管道71以及排气管道72是柔性管道，由橡胶等弹性材料形成，中间部分具有未图示的蛇纹部。通过加热器以及鼓风扇的工作而生成的暖风从循环风路50a排出，并通过吸气管道71导入外桶20内。进而，从外桶20排出的暖风通过排气管道72导入循环风路50a内。这样，暖风在循环风路50a与外桶20之间循环。
烘干装置50进行由暖风的循环实现的循环烘干动作和接下来将循环的暖风的一部分向外部排出的排气烘干动作。在上面板12设置有排气口51，排气口由许多排气孔构成，供暖风排出。
供水装置60的露出至外部的供水口61与从水龙头延伸出的未图示的外部供水软管连接。供水装置60包括供水阀以及洗涤剂容器，通过打开供水阀，来自水龙头的自来水与收容在洗涤剂容器内的洗涤剂一起被供给至外桶20内。供水装置60可以包括洗澡水泵。
在全自动洗衣干衣机1中，进行各种运转模式的洗涤运转、洗涤烘干运转或烘干运转。洗涤运转是仅进行洗涤的运转，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。洗涤烘干运转是连续进行洗涤到烘干的运转，在最终脱水过程之后，接着执行烘干过程。烘干运转是仅进行烘干的运转，仅执行烘干过程。
在洗涤过程以及漂洗过程中，在洗涤脱水桶24内蓄有水的状态下，波轮26向右以及向左旋转。通过波轮26的旋转在洗涤脱水桶24内产生水流。在洗涤过程中，洗涤物通过所产生的水流和水中所含的洗涤剂而被清洗。在漂洗过程中，洗涤物通过所产生的水流而被漂洗。
在中间脱水过程以及最终脱水过程中，洗涤脱水桶24以及波轮26一体地高速旋转。洗涤物通过在洗涤脱水桶24产生的离心力的作用而被脱水。
在烘干过程中，首先进行内部空气循环烘干过程，接着进行外部空气导入烘干过程。在内部空气循环烘干过程中，通过烘干装置50来进行循环烘干动作，暖风在循环风路50a与外桶20之间循环。通过烘干风的循环，洗涤脱水桶24内的温度迅速上升。波轮26旋转，洗涤物在被搅拌的同时被循环的暖风烘干。当洗涤脱水桶24内的温度继续上升，水分从洗涤物蒸发而暖风中含有大量水分时，切换至外部空气导入烘干过程。在外部空气导入烘干过程中，通过烘干装置50来进行排气烘干动作，向循环风路50a导入外部空气的同时从循环风路50a排出一部分循环的暖风。从洗涤物蒸发的水分被有效地从外桶20内排出到机壳10外，容易进行外桶20内的除湿，因此，促进了洗涤物的烘干。
接着，参照图3的(a)至图7，对外桶罩100以及外桶盖23的结构进行详细说明。
图3的(a)是本实施方式的内侧投入口101被外桶盖23闭塞的状态下的外桶罩100的立体图，图3的(b)是本实施方式的卸下外桶盖23的状态下的外桶罩100的立体图。图4是对本实施方式的磁铁160分离后的状态下的吸附台150的周边进行了表示的外桶罩100的主要部分的立体图。

在盖主体200，在背面的外缘部设置有环状的衬垫230。衬垫230由橡胶材 料形成，具有中央部分向外侧鼓出的形状。在外桶盖23将内侧投入口101闭塞的状态下，衬垫230与外桶罩100的内侧投入口101的外周部分接触并被紧压。由此，外桶盖23与外桶罩100之间通过衬垫230来密封。

在左壁面部313以及右壁面部314，在它们的前下部形成有轴孔316。如图3的(a)所示，盖主体200的对应的支承板220的支轴部221插入各个轴孔316。通过左右的轴孔316以及一对支轴部221而形成把手旋转轴R2。把手旋转轴R2与盖旋转轴R1平行。把手300能以把手旋转轴R2为中心相对于盖主体200转动。在前壁面部311以及上壁面部312的背侧，以左右方向排列的方式设置有多个按压肋317。需要说明的是，把手旋转轴R2相当于本发明的第二旋转轴。
吸附金属件320由铁等磁性材料形成，左右的端部具有顶部稍细的长方形的板状。在吸附金属件320的左右端部形成有孔部321。吸附金属件320的下表面构成通过外桶侧吸附面161所产生的磁力而被拉扯的把手侧吸附面322。需要说明的是，吸附金属件320相当于本发明的磁性体，把手侧吸附面322相当于本发明的第一吸附面。
金属件保持体330由树脂材料形成，上表面开口，具有左右尺寸长且上下较薄的长方形的箱状。在金属件保持体330，在底壁面部331的内面形成有形成为吸附金属件320的形状的收容凹部332。在金属件保持体330，在收容凹部332的前侧和后侧，分别设置有两个爪部333a、333b，在收容凹部332的左侧和右侧，分别设置有一个爪部333c。当收容凹部332收容吸附金属件320时，吸附金属件320的上表面的周缘部被这些爪部333a、333b、333c按压。
在金属件保持体330的底壁面部331，在收容凹部332的中央部形成有长圆形的开口部334。收容于收容凹部332的吸附金属件320的下表面即把手侧吸附面322从开口部334面向外部。通过底壁面部331的外表面和把手主体310的前壁面部311的下端面，构成与外桶罩100对置的把手侧配置面335，把手侧吸附面322呈配置于该把手侧配置面335内的状态。在把手侧配置面335，在开口部334的前方即相对于把手侧吸附面322与拉把部315相反的一侧，设置有左右尺寸长的突起部336。突起部336的左右的长度与吸附台150的左右方向的长度大致相等。在突起部336，在开口部334侧形成有把手侧倾斜面337。把手侧倾斜面337相对于把手侧配置面335的倾斜角度例如设置为大致45度。在把手侧吸附面322和外桶侧吸附面161吸附的状态下，把手侧倾斜面337与外桶侧倾斜面152平行。而且，突起部336的顶端部338设置为圆弧形。需要说明的是，把手侧配置面335相当于本发明的第一配置面，把手侧倾斜面337相当于本发明的平行的面。
保持有吸附金属件320的金属件保持体330从下方装配于把手主体310，通过粘接、螺纹固定等固定方法固定于把手主体310。吸附金属件320的上表面被多个按压肋317按压。此外，从把手主体310的上壁面部312向下方延伸的未图示的凸台被插入吸附金属件320的孔部321。这样，吸附金属件320通过多个爪部333a、333b、333c、多个按压肋317等固定于金属件保持体330的收容凹部332内。
接着，对外桶盖23的开闭动作进行说明。
图7的(a)是本实施方式的对外桶盖23关闭的状态下的把手300的周边进行了表示的外桶罩100以及外桶盖23的主要部分的剖面图，图7的(b)是本实施方式的对为了打开外桶盖23而转动把手300的状态下的把手300的周边进行了表示的外桶罩100以及外桶盖23的主要部分的剖面图。需要说明的是，在图7的(a)和(b)中，虽然示出了未被紧压的状态下的衬垫230，但实际上，衬垫230被紧压并与外桶罩100的表面接触。
如图7的(a)所示，当外桶盖23关闭而内侧投入口101被外桶盖23闭塞时，把手300的把手侧吸附面322与外桶罩100的外桶侧吸附面161接触，把手侧吸附面322通过外桶侧吸附面161所产生的磁铁160的磁力而吸附于外桶 侧吸附面161。在此，把手侧吸附面322与外桶侧吸附面161之间的吸附力可以是比衬垫230的弹力更强并且比可能因脱水时外桶20的上下振动、清洗时等情况下洗涤物对外桶盖23的撞击而对外桶盖23产生的向上的力更强的力。
把手侧配置面335向外桶侧配置面151的前方即与把手300的拉把部315相反的方向突出，在突出的面部分与外桶罩100即外桶20的上表面之间形成有空间S。而且，设置于把手侧配置面335的突起部336的把手侧倾斜面337呈与外桶侧倾斜面152平行且几乎相接的状态。
在打开外桶盖23时，用户的手指勾住把手300的拉把部315，将拉把部315向斜前上方抬起。如图7的(b)所示，当抬起拉把部315时，突起部336的把手侧倾斜面337与外桶侧倾斜面152相接，把手300以突起部336为支点向前方转动。由此，把手侧配置面335转动，把手侧吸附面322被从外桶侧吸附面161拉开。此时，拉把部315为力点，突起部336为支点，把手侧吸附面322的与外桶侧吸附面161的接触区域为作用点，根据杠杆原理，会对把手侧吸附面322的接触区域作用向上的大的力，因此，把手侧吸附面322容易被从外桶侧吸附面161拉开。
当把手300向前方转动时，把手旋转轴R2会随之向上方移动，盖主体200即外桶盖23以盖旋转轴R1为中心转动并向上方移动，稍微打开。在外桶盖23转动时，把手旋转轴R2不是向正上方而是向斜后上方移动，因此，会对把手300施加将把手300向后方拉的力。在把手300中，突起部336与外桶侧倾斜面152相接，因此，外桶侧倾斜面152被突起部336向后推，该向后的力被转换为向上的力并作用于突起部336。由此，突起部336沿外桶侧倾斜面152上升，与把手300的转动同时抬升，因此，更容易将把手侧吸附面322从外桶侧吸附面161拉开。
在此，在突起部336形成有与外桶侧倾斜面152平行的把手侧倾斜面337，在突起部336最初与外桶侧倾斜面152相接时，把手侧倾斜面337与外桶侧倾斜面152大体上面接触。因此，能通过把手侧倾斜面337将外桶侧倾斜面152顺利地向后推，通过外桶侧倾斜面152被转换后的向上的力顺利地施加给突起部336。此外，当继续向前方转动把手300时，突起部336的顶端部338会与外桶侧倾斜面152相接。由于突起部336的顶端部338设定为圆弧形，因此，把 手300会顺利转动而不容易卡在外桶侧倾斜面152。
当从外桶侧吸附面161拉开把手侧吸附面322时，用户抓着把手300直接向后方转动外桶盖23，大幅打开外桶盖23。由此，内侧投入口101敞开。
<实施方式的效果>
以上，根据本实施方式，通过以突起部336为支点、以拉把部315为力点、以把手侧吸附面322的与外桶侧吸附面161的接触区域为作用点的杠杆原理，能将把手侧吸附面322容易地从外桶侧吸附面161拉开。由此，用户能容易地进行外桶盖23的开闭操作。
此外，根据本实施方式，由于在把手侧吸附面322的前方，在把手侧配置面335与外桶罩100之间形成有空间S，因此，能在把手侧配置面335靠近把手侧吸附面322的部分，而不是在把手侧配置面335的前端部形成作为支点的突起部336。由此，能缩短从作为支点的突起部336到作为作用点的把手侧吸附面322的接触区域的距离，因此，容易对把手侧吸附面322的接触区域施加向上的较大的力。因此，能更容易地将把手侧吸附面322从外桶侧吸附面161拉开。
而且，根据本实施方式，采用在把手300转动后突起部336与外桶侧倾斜面152相接的结构，将转动把手300后产生的使把手300向后方移动的力转换为向上方的力而作用于突起部336，因此，能使突起部336沿外桶侧倾斜面152上升，能使把手300在转动的同时上升。由此，能更容易地将把手侧吸附面322从外桶侧吸附面161拉开。
而且，根据本实施方式，通过使形成于突起部336的把手侧倾斜面337与外桶侧倾斜面152大体上面接触，能通过把手侧倾斜面337将外桶侧倾斜面152顺利地向后推，能将通过外桶侧倾斜面152转换后的向上的力充分施加于突起部336。由此，能容易地使把手300上升，能更容易地将把手侧吸附面322从外桶侧吸附面161拉开。
而且，根据本实施方式，突起部336的顶端部338设置为圆弧形，因此，在把手300继续向前方转动时，顶端部338不容易卡在外桶侧倾斜面152，能顺利地转动把手300。
而且，根据本实施方式，由于采用了把手侧吸附面322由吸附金属件320 的下表面构成、外桶侧吸附面161由磁铁160的上端面160a构成，即吸附金属件320与磁铁160直接接触的结构，因此，能强力吸附把手侧吸附面322和外桶侧吸附面161。因此，能通过外桶盖23可靠地闭塞内侧投入口101。
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等的任何限制，此外，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，采用了吸附金属件320与磁铁160直接接触的结构。但是，也可以如图8的(a)所示采用如下结构：不在金属件保持体330的底壁面部331设置开口部334，并且用罩154来覆盖磁铁160的上端面160a，由此，吸附金属件320与磁铁160不直接接触。这种情况下，位于金属件保持体330的底壁面部331的外表面的、吸附金属件320的下表面的投影范围成为把手侧吸附面322，位于罩154的上表面的、磁铁160的上端面160a的投影范围成为外桶侧吸附面161。需要说明的是，可以采用在金属件保持体330的底壁面部331设置开口部334并用罩154来覆盖磁铁160的上端面160a的结构，也可以采用不在金属件保持体330的底壁面部331设置开口部334且不用罩154来覆盖磁铁160的上端面160a的结构。在采用上述结构的情况下，理想的是，磁铁160的磁力比上述实施方式的情况下的磁力强。
此外，上述实施方式中，在外桶罩100侧配置有磁铁160，在把手300侧配置有吸附金属件320。但是，也可以如图8的(b)所示，在外桶罩100侧配置吸附金属件170，并在把手300侧配置磁铁340。这种情况下，磁铁340的下端面成为把手侧吸附面341，吸附金属件170的上表面成为外桶侧吸附面171。
而且，在上述实施方式中，示出了将本发明应用于搭载有衣物的烘干功能的全自动洗衣干衣机1的例子。但是，只要是设置有覆盖外桶20的上表面的内侧投入口101的外桶盖23的结构，本发明也能应用于不搭载衣物的烘干功能的全自动洗衣机。
除此之外，本发明的实施方式可以在技术方案所示的技术思想的范围内适当地进行各种变更。
