Description

制冰组件及冰箱 技术领域
本发明涉及制冷电器领域，尤其涉及一种制冰组件及冰箱。
背景技术
制冰机通常设置在冰箱的冷冻室，以借助冷冻室的冷气进行制冰。而对于冷藏室和冷冻室上下分布的冰箱，用户取冰的时候需要弯腰打开冷冻室的门体。为了能够实现方便用户取冰，现有的一些冰箱在冷藏室或者冷藏室门体设置独立的制冰室，制冰机设置于制冰室内，在门体的外侧设置与制冰机关联的分配器，通过风道将冷冻室或者蒸发器室的冷气引入制冰室从而实现给制冰机供冷。这种制冰方式也称之为风冷制冰。
但是，风冷制冰的制冰效率低，且风道占用空间大，这样会占用冰箱本身的储存空间。为此，出现了一种通过制冷管路与制冰机直接接触进行制冰的方式，称之为直冷制冰，直冷制冰有制冰快，占用空间小等优点，但是又因为制冰间室的空间小，制冰机本身的结构复杂，导致安装制冰机时非常麻烦，而且直冷的局限性，制冷剂管的冷量无法最大限度的传递出去，导致制冰间室冷量不足，因此，需要对现有技术进一步的改进。

具体实施方式
以下将结合附图所示的具体实施方式对本发明进行详细描述。但这些实施方式并不限制本发明，本领域的普通技术人员根据这些实施方式所做出的结构、方法、或功能上的变换均包含在本发明的保护范围内。
应该理解，本文使用的例如“上”、“下、”“外”、“内”等表示空间相对位置的术语是出于便于说明的目的来描述如附图中所示的一个单元或特征相对于另一个单元或特征的关系。空间相对位置的术语可以旨在包括设备在使用或工作中除了图中所示方位以外的不同方位。
参考图1到图5所示，本发明的优选的实施方式提供的一种制冰组件100，包括冰模10以及位于冰模10底部的制冷剂管20和加热丝30，冰模10具有多个用于盛装制冰水的冰格，制冷剂管20自冰模10的一端延伸到另一端，加热丝30与制冷剂管20间隔，优选的，可以沿着垂直于冰模20的延伸方向与制冷剂管20间隔，即制冷剂管20与加热丝30错开排布，分别接触冰模20底部的不同位置。制冷剂管20用于给冰模10提供冷量以使冰格中的水冻结，加热丝30用于给冰模10提供热量以 方便冰块从冰模10中释放。本实施例中，以冰模自一端到另一端的纵长的延伸方向为横向，冰块从冰模中释放的一侧为前侧，相对的另一侧为后侧，与横向和前后方向垂直的为竖直方向。
继续参照图2和图3所示，制冰组件100还包括固定于冰模10的下方的排水盘45，排水盘45的一端形成出水口451，排水盘45上设有至少两个向上凸伸的支撑筋452，支撑筋452与加热丝30导热接触并将加热丝30的一部分固定到冰模10。本实施例中，制冷剂管20在冰模10的底部呈U型设置，加热丝30也构造为U型，制冷剂管20和加热丝30相反布置，即U型的开口相反，并且加热丝30位于制冷剂管20的U型的外侧。支撑筋452与排水盘45一体设置并且可以由导热材料构成，比如金属材料，优选为铝制排水盘，可以同时吸收加热丝30的热量以给排水盘45化霜。支撑筋452优选的设置4个，4个支撑筋沿着横向和前后方向分别间隔布置，这样在排水盘45和冰模10底部之间留有空间，形成自冰模10一端到另一端贯通的气流腔44，空气流过气流腔44时可以与制冷剂管20和冰模10进行热交换，形成的冷气可以给设置于制冰组件100下方的储冰盒供冷，以防止储存的冰块融化。无论是制冷剂管20还是加热丝30，通过直接接触的方式进行热交换，冷量和热量传递的效率更高，从而极大的提升了制冰的效率。
制冰组件100还包括用于把制冷剂管固定于冰模的散热件40，散热件40包括连接制冷剂管20的接合部41以及自接合部41向下延伸的翅片，接合部41沿着制冷剂管20延伸的方向与制冷剂管20直接接触，翅片包括间隔设置的多片，每片翅片从冰模10的一端向另一端延伸并且向下延伸到气流腔44内。通过设置散热件40，能够吸收制冷剂管20和冰模10的冷量，并与气流腔44内的空气进行热交换，充分利用制冷剂管20的冷量，并且无需在冰模10的底部设置筋板，只需在安装制冷剂管20到冰模10时把散热件40固定连接于冰模10，整体的结构更加紧凑，从而能够节省制冰室内的空间。
本实施例中优选的，翅片包括与制冷剂管20的U型的两直边位置对应的第一翅片421和第二翅片422，以及位于第一翅片421和第二翅片422之间的第三翅片423，接合部41对应第三翅片423的位置与冰模10直接接触。如此，在制冷的时候可以使更多的冷量传递到翅片，提升冷量利用率；在加热脱冰的时候，也可以从冰模10上吸收热量以用于化霜。接合部41上间隔设置有多个排水孔411，多个排水孔411相对于第三翅片423对称设置，并且制冷剂管20的一部分从多个排水孔411中露出，从而可以使制冷剂管20和冰模10上的结霜能够完全的在加热时化水排出，防止在制冷剂管20和接合部41的接触面上形成冰瘤，影响正常制冰。排水孔411可以沿着自冰模10一端到另一端的方向均匀间隔设置，排水孔10沿着横向的宽度大致与两个排水孔之间的间距相同。其中，散热件40可以通过螺钉或螺栓等固定件安装于冰模10上，或者通过卡扣与冰模卡合，当然，也可以是其它连接方式。
进一步的，制冰组件100还包括固定连接冰模10的底罩50，底罩50包括底壁51以及沿着底壁51的前后分别向上延伸的第一侧壁52和第二侧壁53，排水盘45固定在第一侧壁52和第二侧壁53之间，底罩50沿着冰模10的一端到另一端的方向上，两个端部均设有向上凸伸的凸沿54，排水盘45卡在两个凸沿54之间，第一侧壁52、第二侧壁53以及两个凸沿54实现了排水盘45相对于底罩50在两个方向上的准确定位，排水盘45的位置固定更加可靠。另外，排水盘45的边缘具有向上延伸的边缘455，第一侧壁53和第二侧壁53上分别设有多个倒勾535，排水45盘通过边缘455卡接于多个倒勾535与底罩50固定。另外，底罩50和排水盘45之间可以设置隔热板55，用于隔绝排水盘45到底罩50的热传递，防止底罩50上结霜。
制冰组件100还包括与冰模10固定的壳体15，壳体15具有分别与第一侧壁52和第二侧壁53对应的第一边沿151和第二边沿152，底罩50的一端连接于第一边沿151和第二边沿152；至少两个支撑筋452包 括两个临近底罩50另一端的第一支撑筋453，即临近出水口451的一端，两个第一支撑筋453分别连接于第一边沿151和第二边沿152。具体的，底罩50与第一边沿151通过螺钉16穿过连接，底罩50与第二边沿152卡接，优选的在第二边沿152的一端设置挂钩1521，对应的第二侧壁53的一端设置卡块531，组装时卡块531卡接在挂钩1521上以实现底罩50与第二边沿152的卡接。两个第一支撑筋453相背的一侧分别伸出有支柱4531，第一边沿151和第二边沿152分别延伸出勾部155，支柱4531能够伸入勾部155并且在勾部155内旋转和移动。组装时先通过散热件40把制冷剂管20固定于冰模10，底罩50和排水盘45是预先组装在一起的，将支柱4531与勾部155对接，使得底罩50和排水盘45一起先围绕支柱旋转4531，再沿着勾部155移动，使底罩50的与第二边沿卡接，最后通过螺钉16穿过底罩50和第一边沿151而将底罩50与冰模10固定，即可实现制冰组件100的安装，整个过程非常方便快捷，而且能够可靠的实现制冷剂管20和加热丝30对冰模10的热传递，同时制冷剂管20及冰模10也能够实现与气流腔44内的空气进行热交换，方便给其它部分供冷。另外，脱冰时，排水盘45也可以借助加热丝30的热量进行化霜，化霜水可以直接通过出水口451排出。制冷剂管20和加热丝30同时接触冰模10和导热件40的方式，使得冷量和热量的利用率更高，热传递更快，从而能够提升制冰效率。另外，如需清洗冰模，无论拆卸或者安装，只需将相关部件位置对应，将冰模与底罩连接即可，因此安装非常方便。
继续参照图1到3，冰模10的前端固定连接导冰件17，底罩50的第一侧壁51外侧设有沿其纵长方向延伸的引导筋511，导冰件17向下延伸至与引导筋511平齐的位置，可以在安装底罩50时方便用户了解大致的安装位置，另外为了方便连接导冰件17，可以先将导冰件17连接于冰模10上，导冰件17上可以设置避让孔171，方便螺钉16穿过以连接底罩50和冰模10。制冰组件100还包括位于冰模10一端的驱动机构 60，驱动机构60用于带动设置于冰模10上的排冰器70旋转以进行脱冰。加热丝30的U型的开口端朝向驱动机构60，方便进行电路连接。制冷剂管20的U型的开口端背向驱动机构60，方便与制冷管路连接。
制冷剂管20和冰模10的底部会产生结霜，随着加热丝30启动脱冰，排水盘45同时也会吸热进行化霜，化霜水会直接落入排水盘15，为加快排水，排水盘45可以设置成沿着冰模10连接驱动机构60一端到另一端的方向向下倾斜，倾斜的角度约0.5-2.5度之间，并且排水盘沿着由前向后的方向向下倾斜，倾斜的角度约3-5度之间，为了更高的提升制冷剂管的冷量利用率，多片翅片向下延伸的高度可以沿着与排水盘的倾斜方向匹配，也就是说，沿着横向和前后方向，各个翅片的底部的排水盘的距离大致相同，即多个翅片的底部也与排水盘一致的倾斜，从而翅片与气流腔44内的空气的接触面积更大。出水口451设置在排水盘远离驱动机构60的一端，并且位于排水盘45的后端，即排水盘45的最低处，以使化霜水能够充分排出。而且，在排水盘45远离驱动机构60的一端的端部设有挡水沿456，防止化霜水过多时溢出。
壳体15和冰模10一体成型，以简化制冰组件100整体的安装。壳体15具有前端以及相对的后端，壳体15的后端一体的形成向上延伸的背板157，背板157上设置安装结构，用于将制冰组件100安装于冰箱的内部，驱动机构60可以安装于壳体15上，这样只需将壳体15固定连接于冰箱，组装更加方便。另外，壳体15远离驱动机构60的一端形成向上延伸的端板158，端板158相对冰模10的外侧设置注水槽18，注水槽18临近冰模10的位置设有与冰模10的内腔连通的注水口，也就是说，注水槽18与冰格连通，注水槽18与冰模10也是一体成型，避免了注水过程中的漏水问题。
上述实施方式中的制冰组件，在安装和分离制冷剂管20与冰模10时无需使用工具，安装时只需将散热件40旋转到与制冷剂管20结合的位置，制冷剂管20即相对于冰模10固定，安装非常方便，而且成本更 低。
参照图6所示，本发明提供的实施方式中的冰箱，包括箱体910、活动连接于箱体的门体920以及制冷系统，箱体910限定有制冷间室，箱体内还设有用于将冷风引入制冷间室的风机，制冷间室包括冷藏室91和冷冻室92，冷藏室91和冷冻室92自上而下设置，门体920用于打开和关闭冷藏室91，冷藏室91或门体920设置有制冰室，制冰室内设有制冰组件100(图未示)，制冰组件的下方设置储冰盒200，门体920上设有可选择连通制冰室的分配器(图未示)，经制冰组件100制得的冰块落入储冰盒200进行储存，并能够从分配器排出。本实施例中，制冰室优选设置于冷藏室的门体920上，制冷间室包括冷冻室和冷藏室，当然也可以包括更多的间室，如变温室。
其中，制冷系统包括压缩机913以及连接于压缩机913出口侧的冷凝器，上述制冰组件100的制冷剂管20连接于制冷系统，压缩机913设置于箱体910的底部，用于给冷冻室92和冷藏室91供冷的蒸发器912设置于冷冻室的后部，蒸发器912可以和制冰供冷的制冷剂管20串联或者并联与压缩机和冷凝器的两侧。由于制冰组件100本身的安装更加方便，从而使得冰箱整体的组装也更加方便，从而减小冰箱的制造成本。
