Description

冰箱 技术领域
本发明涉及一种冰箱的制冰用供水单元、冰箱、及冰箱的组装方法。
背景技术
常用的冰箱包括内箱、外箱及填充在它们之间的发泡隔热材料，内箱形成冰箱内的冷藏室、冷冻室等箱内空间，外箱形成外廓，且大多数包括制冰构件，该制冰构件包括制冰用储水槽、供水泵、制冰盘等，用于制冰。
作为制冰构件，例如已知有专利文献JP特开2008-151389号公报所示的构件，在冷藏室等设置制冰用储水槽，从制冰用储水槽经由供水泵及供水管而向制冰盘供给制冰用水。
此外，具体来说，已知有图7所示的制冰装置的供水管及其周边结构。供水泵组件110包括：供水泵112；泵壳体116，支撑供水泵112并将其固定；以及排出管114，将供水泵112排出的制冰用水供给至供水管124。
此外，供水管组件120包括：供水管124、供水管壳体122及供水管承接构件(至少上构件130a)，所述供水管124将排出管114的制冰用水供给至未图示的制冰盘，所述供水管承接构件设置在供水管124与供水管壳体122之间。

发明要解决的问题
如图7及图8所示的现有构成中，受到供水管通道131的成型精度等因素影响，供水口124a在制冰盘方向的长度并不固定。若供水口124a在制冰盘方向过于突出，则使用者将手伸进制冰室后部时可能会受伤。
此外，以往是在形成供水管通道131的下构件130b上组装供水管组件120后，在其上组装供水泵组件110，然后利用接合部115将排出管114与供水管124接合，供水管124的上方位置在组装之前并不固定，导致了难以调整供水口124a在制冰盘方向上的长度。
此外，如上所述，在图7及图8所示的现有例中，将供水管组件120组装至冰箱内箱等后，在其上方组装供水泵组件110，组装步骤数较多。

具体实施方式
以下，参考附图，详细地说明本发明的一实施方式所涉及的冰箱。如图1所示，本实施方式所涉及的供水单元1例如组装在单元安装部32，其设置在冰箱的箱内底30的规定位置上。
另外，以下说明中，前后、左右、上下方向分别指图1所示的箭头方向，供水单元1也以图1为基准，箭头所示方向分别为前后、左右、上下方向。
如图1及图2所示，供水泵12经由流入部13从未图示的制冰用储水罐吸入制冰用水，并将吸入的制冰用水经由排出管14排出至供水管24侧。供水泵12利用固定构件11固定于泵壳10，以覆盖供水泵12的方式设置盖体15及泵壳10，利用内部设置的卡止爪及支撑构件20的卡止槽25，将泵壳10组装至支撑构件20。
如下文所述，通过支撑构件20定位并支撑供水管24。支撑构件20包括供水管插入孔22，用于插入供水管24，经由衬垫21而安装在单元安装部32，其设置在冰箱内箱等的规定位置上。
供水管24上安装有加热器24b，用于用于防止供水管24内部冻结。此外，供水管24上安装有冷气阻挡构件23a、23b，用于防止冷冻室的冷气流入供水泵12侧及冷藏室内。供水管24与排出管14接合，形成制冰用水供给路径，用于将供水泵12供给的制冰用水供给至制冰盘。
如图3及图4所示，支撑构件20包括第一肋20a、第二肋20b、第三肋20c、第 四肋20d，用于在下方底面侧引导并支撑供水管24。肋20a、20b、20c、20d中，肋20a与肋20b相对地位于上游侧，以供水管24为基准相对地接近供水泵12侧。
肋20a具有大致钩状的形状，从支撑构件20向下方延伸，且其下方大致垂直地向供水管24侧弯曲。肋20b设置在与肋20a一同夹持供水管24的位置上。
利用肋20a的大致钩状形状，卡止供水管24，限制供水管24向下方移动，利用肋20a及肋20b，限制供水管24在宽度方向上的移动，从而在下方及宽度方向定位供水管24。
相比肋20a及20b，肋20c及肋20d相对设置在下游侧。肋20c在供水管24的长度方向上延伸，大致平行地设置一对，两者的间隔与供水管24的直径大致相同、或者略大。利用肋20c，可限制供水口24a侧的供水管24在宽度方向上移动。
肋20d设置在供水管24向下游侧的制冰盘方向弯曲的弯曲位置24c的上方附近，沿着供水管24的宽度方向延伸。利用肋20d抵接供水管24的供水口24a侧的弯曲位置24c附近，限制供水管24在供水口24a侧向上方移动。
所述肋20a、20b、20c、20d定位供水管24的下游侧，起到第一定位构件的作用。
此外，如图5及图6所示，支撑构件20具有供水管插入孔22，用于将供水管24连通于供水泵14侧。在供水管插入孔22内，形成有供水管嵌入部22a，其沿着供水管24长度方向延伸。
供水管嵌入部22a可以使供水管24凸状地嵌入供水管插入孔22内。供水管24嵌入供水管嵌入部22a，在规定位置被支撑，可插入且可拉出，但比较困难。
供水管嵌入部22a在第一定位构件的相对上游侧支撑供水管24，对其进行定位，起到第二定位构件的作用。
如图2至图6所示，按前述那样组装供水单元1，并如图1所示将其组装到冰箱的箱内底面30的供水单元安装部32。像这样，在组装至箱内底面30前，供水单元1一体地包括现有泵组件及供水管组件，只要将该供水单元1组装至箱内底面30即可，可省略或简化将供水管组件组装至箱内底面然后再组装泵组件的工序。
此外，在组装了供水单元1的状态下，供水口24a侧的供水管24长度固定。即，供水管24首先从供水泵14侧通过供水管插入孔22内的供水管嵌入部22a不易移动地嵌入规定位置，供水管24不会向制冰盘侧掉落或者向供水泵14侧上升，并利用肋20a、20b、20c、20d限制供水管24向供水管嵌入部22a的下游侧的移动，从而可以保持供水口24a的长度始终固定。
如果像现有技术那样，先组装供水管组件110，然后组装泵组件120，接着将供水管124与排出管114接合等，供水口在制冰盘方向的长度不会受到供水口124a的长度影响，或者受到供水管承接构件130a、130b的供水管通道131的形状、成型精度偏差等影响，利用本实施方式所涉及的供水单元1可以消除这些影响，。
肋20a、20b、20c、20d并不限定于所述说明及附图所示的形状，可以采用如下定位构件：设置于支撑构件20，在供水管24与供水泵12的排出管14的接合部附近支撑供水管24，在供水管24的供水口24a附近限制上下方向的移动，采用以此为核心的各种形状及构成，支撑供水管24并限制其移动，从而将供给口24a的长度固定。
此外，在所述说明中，供水泵12是利用固定构件11固定于泵壳10，但只要泵壳10与支撑构件20卡止，供水泵12也可以直接固定于支撑构件20。
上述说明并不意图限定本发明的主旨。在不脱离本发明的主旨的情况下，本发明包括各种变更、改良。此外，本发明包括其等价物。
