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，而如何实现制冷管路和制冰机冰模有效组合显得尤为重要，既要实现制冰安装方便，又要实现制冰机制冰稳定，且制冰机底部无化霜水或者化霜水能及时排走。因此，需要对现有技术进一步的改进。
发明内容

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4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，可以沿着大致垂直于冰模20的延伸方向上与制冷剂管20间隔。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的方向为前侧，相对的另一侧为后侧，与横向和前后方向垂直的为竖直。
制冰组件100还包括导热件40以及围设于导热件40外侧的底罩50，导热件40设置于冰模10和底罩50之间，制冷剂管20和加热丝30位于冰模10和导热件40之间，导热件40支撑制冷剂管20的至少一部分和加热丝30的至少一部分，使得制冷剂管20的至少一部分和加热丝30的 至少一部分与冰模10直接接触而将冷量和热量传递给冰模10。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。
具体的，导热件40包括与冰模10相邻的顶壁41、相对的底壁42以及连接顶壁41和底壁42的两个侧壁43，顶壁41、底壁42以及两个侧壁43围成有沿着冰模10的一端到另一端的方向贯通的气流腔44，气流腔44内设有自顶壁41延伸到底壁42的散热筋45，底壁42的一端形成有出水口421，底罩50包围底壁42以及两个侧壁43，导热件40通过底罩50固定于冰模10。这样，组装时只需把制冷剂管20和加热丝30置于冰模10和导热件40之间，底罩50与冰模10连接，即可实现制冷剂管20和加热丝30对冰模10的热传递，安装非常方便，同时导热件40及其散热筋45也能够实现与气流腔内的空气进行热交换，方便给其它部分供冷，例如制冰组件100下方的储冰盒，以防止储存的冰块融化。另外，脱冰时，导热件40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421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。
参照图3所示，导热件40的顶壁41上设有分别与制冷剂管20和加热丝30的外形匹配的第一凹槽411和第二凹槽412，制冷剂管20的一部分收容于第一凹槽411，加热丝30的一部分收容于第二凹槽412。其中制冷剂管20与冰模10接触的部分构造为U型，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，并且制冷剂管20位于加热丝30U型的内侧。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。为加快冷量的传导，散热筋45设置成与第一凹槽411的位置对应，这样散热筋42距离制冷剂管20的距离更近，利于吸收制冷剂管20的冷量，从而提升制冷效率。导热件40优选为金属制成，如一体成型的铝制件，制造方便同时热传导率高。
另外，为了进一步提升制冷剂管20与冰模10的热交换效率，导热件10的顶壁41上还设有沿着冰模10的一端到另一端的方向延伸的凸部413，凸部413与冰模10的底部直接接触，凸部413位于制冷剂管的U型内部，导热件40接收制冷剂管20上的冷量并进一步通过凸部413再传导给冰模10，加快冷量的传导，从而提升制冰效率。而且凸部413对应气流腔44的表面形成凹槽414，也就是说，导热件10的顶壁41的壁厚大致是一致的，如此能够增大与气流接触的表面积，从而提升热交换效率。制冷剂管20被冰模10和导热件40包裹，导热件40的气流腔44内的表面上会产生结霜，随着加热丝30启动脱冰，导热件40同时也会吸热进行化霜，化霜水会直接沿着气流腔44内的表面流到底壁42，为加快排水，底壁42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α约0.5-2.5度之间，并且底壁42沿着由前向后的方向向下倾斜，倾斜的角度β约3-5度之间，出水口421设置在底壁42远离驱动机构60的一端，并且位于导热40件的后端，即底壁42的最低处，以使化霜水能够充分排出。而且，在底壁42远离驱动机构60的一端的端部设有挡水沿423，防止化霜水过多时溢出。
继续参照图2和图3，底罩50包括对应两个侧壁的第一围壁51和第二围壁52，每个围壁与对应的侧壁两者之一上设有卡凸511，每个围壁与对应的侧壁两者之另一上设有卡槽431，导热件40和底罩50通过卡凸511和卡槽431固定连接。优选的，本实施方式中，每个侧壁43上沿着冰模10从一端到另一端的延伸方向上间隔设置三个卡槽431，第一围壁51和第二围壁52上分别设置与卡槽431对应的卡凸511，安装时，只需将导热件40与底罩50位置对应，将导热件40压入第一围壁51和 第二围壁52之间，听到卡合声即安装到位。底罩50和导热件40的底壁之间可以设置隔热板55，用于隔绝导热件40到底罩50的热传递，防止底罩50上结霜。
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，导热件40卡在两个凸沿54之间，第一围壁51、第二围壁52以及两个凸沿54实现了导热件40相对于底罩50在两个方向上的准确定位，导热件40的位置固定更加可靠。
制冰组件100还包括与冰模10固定的壳体15，壳体15具有分别与第一围壁51和第二围壁52对应的第一边沿151和第二边沿152，第一边沿151和第二边沿152分别延伸出设有卡勾或勾槽的凸耳153，两个围壁上分别设有勾槽或卡勾，底罩50和壳体15通过勾槽和卡勾固定连接。如此，导热件40可以保持在相对固定的位置，从而能够使制冷剂管20和加热丝30保持与冰模10接触，热传递更加可靠。本实施例中优选的，第一边沿151和第二边沿152分别向下延伸出两个凸耳153，即冰模10的前端设有两个凸耳153，冰模10的后端设有两个凸耳153，凸耳153上设置勾槽，两个围壁51、52上对应设置卡勾，冰模10的前端固定连接导冰件16，为了防止脱冰时掉落的冰块碰到卡勾或者勾槽，导冰件16向下延伸至与卡勾平齐的位置。
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的后端形成向上延伸的背板155，背板155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156，端板156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，无需在冰模的底部设置散热翅片，安装时只需将各部件位置对准，将底罩相对于冰模卡合固定，冰模在导热件的作用下可直接接触制冷剂管和加热丝，缩小了制冰的安装空间，又可增大制冷管路的蒸发面积，且无需额外加热丝加热导热件以化霜排水，安装非常方便，而且成本更低。
参照图5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。
