Description

洗衣机 技术领域
本发明涉及洗衣机。
背景技术
以往，提出了一种抽屉式洗衣机，该洗衣机以如下方式配置：将上侧敞开的箱柜以可从前方抽出的方式收容于前表面敞开的外壳内，并在箱柜中内置能储存洗涤水并能进行洗涤、脱水的洗涤桶(参照专利文献1)。洗涤桶经由具有缓冲功能的悬架支承于箱柜的底面。而且，箱柜能通过设于箱柜与外壳之间的滑动部沿前后方向直线移动。
该抽屉式洗衣机可通过尽量减小滑动部内部的阻力即专利文献1的结构中滚轮与导轨之间的阻力，来轻松地进行箱柜从外壳抽出的动作。但是，当箱柜相对于外壳容易沿前后方向移动时，在脱水时等发生的洗涤桶的振动还未被悬架完全减振就传递给箱柜的情况下，箱柜变得容易沿前后方向剧烈振动。
通常，在被封闭的箱柜的前表面部即门部与外壳的前表面之间安装有闩锁，门部以不会打开的方式被锁住。但是，由于闩锁设有一定程度的游隙，因此存在以下的隐患：当箱柜沿前后方向剧烈振动时，门部与外壳的前表面之间会反复发生轻微碰撞，导致产生噪音或门部等发生破损。

发明内容
发明所要解决的问题
本发明是鉴于该问题而完成的发明，其目的在于，抑制在从外装壳内抽出 洗涤桶的结构的洗衣机中由于洗涤桶的振动导致门部与外装壳之间反复发生轻微碰撞而引发噪音、门部等破损的情况发生。
用于解决问题的方案
本发明的主要方式的洗衣机具备：外装壳，在前表面具有出入口；洗涤桶，可通过所述出入口出入于所述外装壳，进行洗涤物的洗涤和脱水；保持部，配置于所述洗涤桶的下方，经由悬架来保持所述洗涤桶；门部，在所述洗涤桶的前方固定于所述保持部，在所述洗涤桶收容于所述外装壳的状态下堵住所述出入口；滑动机构部，设置于所述保持部与所述外装壳之间，使所述保持部与所述洗涤桶和门部一起沿前后方向直线移动；以及连结部，连结所述悬架和所述保持部。在此，所述连结部具有防振部，所述防振部抑制所述洗涤桶的前后方向的振动经由所述悬架向所述保持部传递。
通过上述结构，由于能抑制保持部的前后方向的振动，因此能抑制由洗涤桶的振动引起的门部与外装壳之间反复发生轻微碰撞的情况发生，能抑制噪音、门部等的破损的产生。
本方式的洗衣机可以采用如下结构：所述防振部包括移动路和移动体，所述移动路设置于所述保持部侧，所述移动体设置于所述悬架侧并沿前后方向在所述移动路移动。在这种情况下，所述移动体在所述移动路上移动时的摩擦阻力小于所述滑动机构部使所述保持部移动时的摩擦阻力。
通过上述结构，由于移动体比起保持部更容易在前后方向上移动，因此能通过防振部有效地抑制保持部的前后方向的振动。
在采用上述结构的情况下，可以进一步采用如下结构：所述移动体以在左右方向上不动的方式由所述移动路引导。
当采用这样的结构时，洗涤桶在左右方向上不会发生比前后方向上更大幅的振动，外装壳的左右方向的尺寸不会大到超出必要。
本方式的洗衣机可以采用如下结构：所述门部经由缓冲构件固定于所述保持部。
通过上述结构，由于能通过缓冲构件吸收保持部的振动，因此振动难以传递至门部，门部与外装壳之前的轻微碰撞更加难以发生。
发明效果
根据本发明，能抑制在从外装壳内抽出洗涤桶的结构的洗衣机中由于洗涤桶的振动导致门部与外装壳之间反复发生轻微碰撞而引发噪音、门部等破损的情况发生。
本发明的效果以及意义通过如下所示的实施方式的说明来进一步明确。不过，以下的实施方式只是实施本发明时的一个示例，本发明不受以下的实施方式所记载的内容的任何限制。

具体实施方式
以下，参照附图对作为本发明的洗衣机的一实施方式的全自动洗衣机1加以说明。
图1(a)是全自动洗衣机1的前方立体图，图1(b)是表示上下层叠了两个全自动洗衣机1的状态的前方立体图。图2是示出洗涤桶20被往外装壳10的前方抽出的状态的全自动洗衣机1的后方立体图。图3是图1(a)的沿A-A’线剖开的全自动洗衣机1的侧面剖视图。
参照图1至图3，全自动洗衣机1具备：外装壳10、洗涤桶20、驱动单元30、排水单元40、给水单元50、前后左右四个悬架60、前后左右四个连结部70、左右两个保持板80、门部90、以及左右一组滑动导轨100。保持板80相当于本发明的保持部，滑动导轨100相当于本发明的滑动机构部。
全自动洗衣机1是所谓的抽屉式洗衣机，用户将洗涤桶20从外装壳10朝向前方抽出，并从上方将洗涤物投入被抽出的洗涤桶20，再重新将洗涤桶20收容于外装壳10内，对洗涤物进行洗涤。如图1(b)所示，由于能将两个全自动洗衣机1上下层叠并设置于洗手间等的地板内，因此能有效地利用设置空间进行洗涤物的分洗。
外装壳10具有大致长方体的箱状，其前表面几乎整体作为出入口11开口。在外装壳10的左右的内侧面，在出入口11的附近上部设置有卡合部12。此外，在外装壳10的后表面，在上部形成有给水连接口13，在下部形成有排水连接口14。在排水连接口14设置有排水接头15。进而，在外装壳10的底面，于四角设置有脚部16。
洗涤桶20包括外桶21和洗涤脱水桶22。在外桶21的上表面形成有洗涤物的投入口23，并且在投入口23的后方形成有注水口24。投入口23由开闭自如的内盖25覆盖。在外桶21的外周面，在前侧的右端和左端的位置、以及后侧的右端和左端的位置，分别设置有悬架安装部26。悬架安装部26可以与外桶21一体形成，也可以与外桶21分体形成并固定于外桶21。需要说明的是，在外装壳10内，洗涤桶20与外装壳10之间的间隙取为前后方向上比左右方向上大。
在外桶21内配置有洗涤脱水桶22。洗涤脱水桶22在外桶21内以沿着铅直方向延伸的旋转轴为中心进行旋转。在洗涤脱水桶22的内周面，遍及整周地形成有许多脱水孔22a。此外，在洗涤脱水桶22的上部设有平衡环27。进而，在洗涤脱水桶22的底部配置有波轮28。在波轮28的表面呈放射状地设有多个叶片28a。
在外桶21的外底部配置有驱动单元30和排水单元40。驱动单元30产生驱动洗涤脱水桶22和波轮28的转矩。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，通过该离合器机构所进行的切换操作，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28而仅使波轮28旋转，在脱水过程中，将驱动电机31的转矩传递给波轮28和洗涤脱水桶22而使波轮28和洗涤脱水桶22一体旋转。
排水单元40包括：排水阀41、排水管42以及内部排水软管43。在排水阀41的一端连接有排水管42，在排水阀41的另一端连接有内部排水软管43。排水管42与形成于外桶21的底部的排水口(未图示)连接。内部排水软管43从内侧连接于排水连接口14的排水接头15。外部排水软管(未图示)从外侧连接于排水接头15。当排水阀41打开时，蓄积于洗涤脱水桶22和外桶21的水通过排水管42、内部排水软管43以及外部排水软管排出机外。
内部排水软管43在洗涤桶20收容于外装壳10的状态下被配置成左右蛇形并收纳于外装壳10的后部。当洗涤桶20被抽出外装壳10时，内部排水软管43被洗涤桶20抽拉，从蛇形状态变形成笔直状态。
在外装壳10内的上部后方配置有给水单元50。给水单元50包括：给水阀51、给水管52以及连接管53。在给水阀51的一端连接有给水管52，在给水阀51的另一端连接有连接管53。在洗涤桶20收容于外装壳10的状态下，给水管52的流出口52a面向外桶21的注水口24。连接管53在给水连接口13内面向外部，连接于延伸自水龙头的给水软管(未图示)。当给水阀51打开时，自来水通过给水管52和注水口24被供给至外桶21内。
洗涤桶20经由前后左右四个悬架60，保持于配置在洗涤桶20的下方的左右两侧的保持板80。悬架60的上端部固定于洗涤桶20的悬架安装部26，悬架60的下端部经由连结部70固定于保持板80。悬架60以可缓冲的方式支持洗涤 桶20。保持板80在前后方向上为长边，右侧的保持板80承接右侧的前后两个悬架60，左侧的保持板80承接左侧的前后两个悬架60。连结部70通过具有防振装置500，从而具有抑制洗涤桶20的前后方向的振动经由悬架60向保持板80传递的功能。
对悬架60和连结部70的详细结构追加说明。
门部90通过L字形的安装金属件81固定于左右的保持板80的前端部。在门部90的上部设置有锁定装置91，该锁定装置91用于使门部90相对于外装壳10保持关闭状态。
锁定装置91包括：操作杆92、联杆机构93以及左右两个闩锁94。如图3所示，当门部90关闭时，闩锁94卡合于外装壳10的卡合部12。当门部90要向前方移动时，闩锁94挂在卡合部12，由此，门部90保持关闭状态。当用户将操作杆92朝向解除方向操作时，通过联杆机构93的动作，闩锁94向上方移动，解除闩锁94与卡合部12的卡合。由此，呈洗涤桶20与门部90一起从外装壳10抽出的状态。需要说明的是，在闩锁94卡合于卡合部12的状态下，闩锁94与卡合部12之间设有少许作为游隙的间隙。
左右的保持板80能分别通过左右的滑动导轨100与洗涤桶20和门部90一起沿着前后方向直线移动。滑动导轨100包括前后方向尺寸长的固定导轨101和可动导轨102。固定导轨101固定于外装壳10的内侧面的下部，可动导轨102固定于保持板80的与外装壳10的内侧面对置的面。在固定导轨101的内部设置有滚轮(未图示)，可动导轨102以被滚轮传送的方式在固定导轨101内沿前后方向移动。由此，固定于可动导轨102的保持板80与洗涤桶20和门部90一起沿着前后方向顺利地移动。
全自动洗衣机1进行各种运转模式的洗涤运转。洗涤运转依次执行洗涤过程、中间脱水过程、漂洗过程以及最终脱水过程。
在洗涤过程和漂洗过程中，在洗涤脱水桶22内蓄有水的状态下，波轮28向右方和左方旋转。通过波轮28的旋转在洗涤脱水桶22内产生水流。在洗涤过程中，通过产生的水流和水中所含的洗涤剂对洗涤物进行洗涤。在漂洗过程中，通过产生的水流对洗涤物进行漂洗。
在中间脱水过程和最终脱水过程中，洗涤脱水桶22和波轮28一体地高速旋转。通过在洗涤脱水桶22产生的离心力的作用，对洗涤物进行脱水。
接着，对悬架60和连结部70的详细结构进行说明。
图4(a)至(c)是表示悬架60和连结部70的结构的图。图4(a)是从后方观察右前方的悬架60和连结部70的立体图，图4(b)是将悬架60和连结部70在前后方向的中央部剖开的正面剖视图。图4(c)是设置于连结部70的防振装置500的侧面剖视图。图4(a)、(b)中描出了外桶21的右前方的悬架安装部26，省略了外桶21的其他部分的图示。
悬架60包括阻尼器部200和弹簧部300。阻尼器部200具备：阻尼器210、上部安装部220以及下部安装部230。
阻尼器210包括：缸体211、活塞杆212以及上部杆213。在缸体211内封入有油。活塞杆212在上端部具有活塞(未图示)，当活塞杆212上下移动时，活塞一边滑动接触缸体211的内周面，一边在缸体211内上下移动。上部杆213在缸体211的上端部与缸体211一体设置。需要说明的是，虽然在本实施方式中，阻尼器210是缸体211内封入有油的液压阻尼器，但阻尼器210也可以是缸体211内封入有空气的空气阻尼器。
上部安装部220包括：上部第一缓冲体221、上部第二缓冲体222以及上部安装板223。上部第一缓冲体221和上部第二缓冲体222具有大致圆筒状，由橡胶等弹性材料形成。上部第一缓冲体221和上部第二缓冲体222以上下夹持的方式固定于上部安装板223。上部杆213经由上部第一缓冲体221和上部第二缓冲体222固定于上部安装板223。
下部安装部230包括：下部第一缓冲体231、下部第二缓冲体232以及下部安装板233。下部第一缓冲体231和下部第二缓冲体232具有大致圆筒状，由橡胶等弹性材料形成。下部第一缓冲体231和下部第二缓冲体232以上下夹持的方式固定于下部安装板233。活塞杆212的下端部经由下部第一缓冲体231和下部第二缓冲体232固定于下部安装板233。
弹簧部300包括：螺旋弹簧301、上部承接部302以及下部承接部303。上部承接部302固定于缸体211的下端部，承接螺旋弹簧301的上端部。下部承 接部303在下部安装部230的上端部的位置固定于活塞杆212，承接螺旋弹簧301的下端部。
连结部70具备安装台400和防振装置500。安装台400形成为上下扁平的大致长方体形状，在其中央部具有圆筒状的收容孔401。
防振装置500包括滑块510和导轨520。防振装置500相当于本发明的防振部。滑块510相当于本发明的移动体，导轨520相当于本发明的移动路。
滑块510形成为上下扁平的大致长方体形状，在其下表面的中央部具有沿前后方向延伸的截面长方形的槽部511。在滑块510的上表面，通过螺钉402固定有安装台400。滑块510在槽部511附近的四个部位以沿前后方向按规定间隔排列的方式转动自如地内置有球体512。球体512局部露出至槽部511内。
导轨520具有前后方向上细长的大致长方体形状。导轨520的前后尺寸长于滑块510的前后尺寸。导轨520通过螺钉521固定于保持板80的上表面。
当滑块510的槽部511嵌入导轨520时，四个部位的球体512抵接于导轨520的左右侧面和上表面。由此，当滑块510在导轨520上沿前后方向移动时，由于与导轨520接触的球体512滚动，因此滑块510与导轨520之间的摩擦阻力变小。需要说明的是，设置成滑块510与导轨520之间的摩擦阻力在可动导轨102相对于固定导轨101沿前后方向移动时小于可动导轨102与固定导轨101之间产生的摩擦阻力。此外，滑块510由于是槽部511嵌入导轨520的结构，因此被导轨520沿前后方向引导，沿左右方向不能移动。
悬架60的上端部通过使上部安装板223由螺钉240固定于悬架安装部26的下表面，从而固定于悬架安装部26。在悬架安装部26形成有圆筒状的收容孔26a，在该收容孔26a收容有上部安装部220的上部。此外，悬架60的下端部通过使下部安装板233由螺钉250固定于安装台400的上表面，从而固定于连结部70。这时，在安装台400的收容孔401收容有下部安装部230的下部。
悬架60通过弹簧部300弹性支承洗涤桶20，并通过阻尼器部200使弹簧部300的振动衰减。在脱水过程中，虽然洗涤桶20因洗涤脱水桶22内的洗涤物的偏置等而在前后、左右以及上下方向上发生振动，但这样的洗涤桶20的振动通过悬架60被吸收。但是，悬架60无法完全吸收振动，一部分振动会经由悬架 60传递给连结部70。
如上所述，防振装置500设置于连结部70，传递至连结部70的前后方向上的振动通过滑块510随着振动在导轨520上沿前后方向移动而被吸收。由此，前后方向上的振动传递给保持板80的情况得到抑制。在此，由于滑块510与导轨520之间的摩擦阻力小于滑动导轨100的可动导轨102与固定导轨101之间的摩擦阻力，滑块510比可动导轨102更容易沿前后方向移动，因此，由防振装置500吸收后传递至保持板80的振动变成无法使可动导轨102移动的极微弱的力。因此，保持板80不管是否装配于滑动导轨100，在洗涤桶20振动时都难以在前后方向上振动。如此一来，在全自动洗衣机1中防止了由于洗涤桶20的振动而导致固定于保持板80的门部90与外装壳10的出入口11的周缘之间反复发生轻微碰撞的情况发生。
(实施方式的效果)
以上，根据本实施方式，由于设计成通过设置于连结部70的防振装置500来抑制洗涤桶20的前后方向上的振动通过悬架60向保持板80传递，因此能抑制容易通过滑动导轨100进行移动的保持板80在前后方向上的振动。由此，能抑制由洗涤桶20的振动引起的门部90与外装壳10之间反复发生轻微碰撞的情况发生，能抑制噪音、门部90等的破损的产生。
而且，根据本实施方式，防振装置500包括导轨520和在导轨520上沿前后方向移动的滑块510，滑块510与导轨520之间的摩擦阻力小于滑动导轨100的可动导轨102与固定导轨101之间的摩擦阻力。因此，滑块510比可动导轨102更容易沿前后方向移动，由此，能通过防振装置500有效地抑制保持板80的前后方向上的振动。
而且，根据本实施方式，由于防振装置500构成为滑块510通过导轨520以在左右方向上不动的方式进行引导，因此，洗涤桶20不会在左右方向上比前后方向上更大幅地振动，外装壳10的左右方向的尺寸不会大到超出必要。
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，此外，本发明的实施方式也可以在上述之外进行各种变更。
(变更例1)
图5是表示变更例1所涉及的全自动洗衣机1的结构的主要部分的剖视图。需要说明的是，在图5中，省略了悬架60和连结部70的图示。
在上述实施方式中，门部90通过安装金属件81直接安装于左右的保持板80的前端部。与此相对，在本变更例中，门部90经由由橡胶等弹性材料形成的缓冲构件110固定于左右的保持板80。更详细地，在固定于保持板80的安装金属件81的前表面与门部90的后表面之间夹有缓冲构件110的状态下，安装金属件81和门部90由凸肩螺钉120来固定。
当采用这样的结构时，由于能通过缓冲构件110来吸收保持板80的振动，因此振动难以传递至门部90，门部90与外装壳10的出入口11的周缘之间的轻微碰撞越发难以产生。
进而，在本变更例中，在门部90的后表面与外装壳10的前表面的出入口11的周缘部之间设置有由橡胶等弹性构件形成的缓冲垫构件130。
当采用这样的结构时，即使在门部90与外装壳10的出入口11的周缘之间稍微产生轻微碰撞，对门部90和外装壳10的冲击也会通过缓冲垫构件130被缓释，越发难以产生噪音、破损。
(其他变更例)
在上述实施方式中，洗涤桶20由左右两个保持板80保持。但是，保持洗涤桶20的保持部的结构不限于此，例如如图6(a)所示，也可以采用设有前后左右四个保持板80A且左侧的两个保持板80A安装于左侧的可动导轨102的结构。或者，如图6(b)所示，也可以采用设有一个保持板80B且在该保持板80B的左右的侧面安装有左右的可动导轨102的结构。进而，作为保持部，也可以采用如图6(c)所示的、设有上表面敞开的箱柜80C并在该箱柜80C的左右的侧面下部安装有可动导轨102的结构。
此外，在上述实施方式中，防振装置500由滑块510和导轨520构成。但不限于此，如图7所示，防振装置500可以采用如下结构：具有滚轮531的移动块530固定于安装台400的下表面，该移动块530在槽状的导轨540上沿前后方向移动。在该情况下，滚轮31与导轨540之间的摩擦阻力小于在可动导轨102相对于固定导轨101沿前后方向移动时可动导轨102与固定导轨101之间产 生的摩擦阻力。
进而，在上述实施方式中，为了使保持有洗涤桶20的保持板80沿前后方向移动，使用了包括固定导轨101和可动导轨102的滑动导轨100。但不限于此，例如，作为滑动机构部，也可以采用如下结构：在外装壳10的左右的内侧面的下部设有滚轮，该滚轮与设于左右的保持板80的底面的导轨接触并旋转，由此使导轨被沿前后方向传送。
进而，在上述实施方式中，悬架60由阻尼器部200和弹簧部300构成。但是，悬架60也可以只由阻尼器部200或弹簧部300来构成。
进而，在上述实施方式中，示例了全自动洗衣机1，但本发明也可以适用于除了洗衣功能以外还具有干衣功能的全自动洗衣干衣机。
除此之外，本发明的实施方式可以在权利要求书中所公开的技术思想的范围内适当地进行各种变更。
