本申请要求合肥华凌股份有限公司、合肥美的电冰箱有限公司、美的集团股份有限公司于2018年11月28日提交的、实用新型名称为“冰箱”的、中国专利申请号“201821979292.8”的优先权。
技术领域
本申请涉及制冷领域，尤其是涉及一种冰箱。
背景技术
相关技术的一些冰箱设有制冰装置，制冰装置一般放置在门体或者是冷藏间室内。当制冰装置放置在门体上时，通过风道将冷冻蒸发器产生的冷气引入到制冰装置中进行制冰。由于冷冻蒸发器的主要冷量要供应冷冻室，且从冷冻蒸发器到制冷装置的进风距离长，冷量途中损失较大，最终到达制冷装置的冷量有限，导致制冰量偏小，冰箱能效偏低。
当制冰装置放置在冷藏间室内时，制冰装置包括制冰蒸发器，制冰蒸发器通常放置于箱胆内的冷藏风道盖板后方，由于制冰蒸发器温度非常低(约零下25度)，而冷藏间室的温度一般在5度左右，制冰蒸发器工作时，容易通过制冰蒸发器周围的密封搭接处漏冷至冷藏室，造成冷藏室结冰，并影响冷藏室内的温度造成冷藏室控温故障。
申请内容

如图1-图5所示，根据本申请实施例的冰箱100，包括：箱体1、制冰机2、固定支架3、制冰进风管4、制冰回风管5和制冰蒸发器6。其中箱体1包括箱壳10和箱胆11，箱胆11设在箱壳10内，箱壳10和箱胆11之间设有发泡层。具体地，箱壳10和箱胆11之间限定出发泡空间，通过对发泡空间进行发泡以形成发泡层。
箱胆11内设有冷藏间室，箱壳10上设有装配口12和用于打开或封闭装配口12的装配盖13。具体地，箱胆11内还可以设有与冷藏间室间隔的冷冻间室。装配盖13用于打开或封闭箱壳10上的装配口12。在本申请的具体示例中，装配口12位于箱壳10的后侧壁上，从而可以提高冰箱100的外观美观性。
制冰机2设在冷藏间室内，制冰机2上设有风道入口和风道出口20。可以理解的是，制冰机2包括用于制冰的制冰室，制冰机2还包括制冰风机21，风道入口和风道出口20分别与制冰室连通，制冰风机21转动时，冷气从风道入口进入到制冰室内以对液体进行制冰，制冰室内的空气可以从风道出口20排出制冰室，从而在制冰室内可以形成冷气循环以达到制冰需求。具体地，制冰机2还可以包括储冰桶，储冰桶用于储存冰块。在图2所示的示例中，制冰机2位于冷藏间室的左上方。
具体地，冷藏间室内还设有冷藏风道盖板16、冷藏蒸发器9和冷藏风道组件17，冷藏风道盖板16设在冷藏间室的内壁上，冷藏风道盖板16和冷藏间室的内壁之间限定出安装空间，冷藏风道组件17和冷藏蒸发器9安装在安装空间内，冷藏风道组件17将冷藏蒸发器9产生的冷空气传送至冷藏间室内。
固定支架3、制冰进风管4和制冰回风管5分别预埋在发泡层内，固定支架3内设有风道空间30，制冰进风管4分别与风道入口和风道空间30连通，制冰回风管5分别与风道出口20和风道空间30连通。制冰蒸发器6通过装配口12装配至风道空间30内。优选地，制冰进风管4连接至风道空间30的顶壁，制冰回风管5连接至风道空间30的下部。从而可以充分利用风道空间30内的冷量。
在本申请的具体示例中，箱胆11上设有制冰机进风槽口18和制冰机回风槽口19， 风道入口与制冰机进风槽口18密封配合，制冰机回风槽口19与风道出口20密封配合。制冰进风管4与制冰机进风槽口18密封配合，制冰回风管5与制冰机回风槽口19密封配合。具体地，上述的密封配合均可以是采用密封海绵进行密封。
具体而言，装配口12与风道空间30在前后方向正对或者是斜对设置，通过装配口12将制冰蒸发器6装配到风道空间30内，可以理解的是，发泡层内预埋有与制冰蒸发器6相连的冷媒管。制冰蒸发器6可以对风道空间30的空气进行制冷，冷气通过制冰进风管4流向风道入口，冷气从风道入口进入到制冰机2内进行制冰。
制冰机2内的冷气通过风道出口20排向制冰回风管5，冷气通过制冰回风管5排回到风道空间30内进行继续制冷，从而制冰机2、风道空间30、制冰进风管4和制冰回风管5之间可以形成冷气的循环风道，保证了制冰蒸发器6产生的冷气可以进入到制冰机2内，保证了制冰机2的冷量需求。
根据本申请实施例的冰箱100，在装配时，将固定支架3、制冰进风管4和制冰回风管5预定位在发泡空间内，然后箱体1发泡即对发泡空间进行发泡后可以将固定支架3、制冰进风管4和制冰回风管5固定在发泡层内。待箱体1发泡完成后，将制冰蒸发器6通过装配口12装配在固定支架3的风道空间30内，然后通过装配盖13封闭装配口12以避免冷量泄露。
根据本申请实施例的冰箱100，通过将固定支架3、制冰进风管4和制冰回风管5预埋在发泡层内，制冰蒸发器6安装在固定支架3内，使得制冰蒸发器6与冷藏间室之间通过发泡层间隔开，可以避免制冰蒸发器6漏冷到冷藏间室内，不仅可以保证制冰机2的冷量需求，还可以避免因漏冷而发生冷藏间室温控故障。同时通过将制冰机2设在冷藏间室内且将制冰蒸发器6设在发泡层内，可以减少冷量传输路径，减少冷量损失。又由于通过打开装配盖13就可以对制冰蒸发器6进行维修，提高了维修便利性。
在本申请的一些实施例中，如图1和图3所示，冰箱100还包括保温件7，保温件7设在装配盖13和制冰蒸发器6之间。也就是说，制冰蒸发器6和装配盖13之间设有保温件7，从而可以进一步避免冷量泄露。具体地，保温件7可以为发泡件、VIP保温板或者海绵。
具体地，保温件7与装配盖13为独立加工件，保温件7放置在装配口12内。也就是说，保温件7和装配盖13为两个独立的元件，在装配冰箱100时，先将保温件7放置在装配口12内，然后将装配盖13安装至箱壳10上。从而当保温件7和装配盖13中的其中一个出现损坏时，可以仅更换出现损坏的部件，降低维修成本。
当然可以理解的是，保温件7也可以固定在装配盖13的朝向制冰蒸发器6的端面 上，从而便于冰箱100的装配。在本申请的具体示例中，装配盖13通过固定连接件例如螺钉安装至箱壳10上。更具体地，箱壳10上设有容纳槽，装配盖13装配在容纳槽内使得装配盖13与箱壳10的其余部分平齐，从而可以提高冰箱100的外观美观性。
如图1所示，在本申请的一些实施例中，装配口12内设有止挡板14，保温件7的朝向制冰蒸发器6的端面与止挡板14接触。从而可以避免保温件7从装配口12内脱落。
根据本申请的一些实施例中，如图1所示，箱胆11的外表面设有凹槽15，固定支架3设有支撑脚31，支撑脚31伸入支撑在凹槽15内。从而通过支撑脚31与凹槽15的配合实现将固定支架3预定位在箱胆11上，避免在发泡过程中，固定支架3的位置发生偏移。具体地，支撑脚31形成为平板状，凹槽15的形状与支撑脚31的形状相同。
进一步地，支撑脚31为多个且在上下方向上间隔设置，凹槽15为多个，多个支撑脚31一一对应地支撑在多个凹槽15内。从而通过设置多个支撑脚31与多个凹槽15一一对应配合，可以提高固定支架3的固定牢靠性。在本申请的一些具体示例中，如图1所述，支撑脚31为两个，从而可以节约成本。
如图1所示，在本申请的一些实施例中，风道空间30的底壁设有盛水空间32，盛水空间32设有排水口33，冰箱100还包括预埋在发泡层内的排水管(图未示出)，排水管与排水口33连通。具体而言，制冰蒸发器6在制冷过程中会产生冷凝水，产生的冷凝水会滴落到盛水空间32内，冷凝水通过排水口33和排水管排出。从而可以避免因制冰蒸发器6产生冷凝水而使得箱体1出现水滴而降低用户的使用舒适性。需要进行说明的是，排水管排出的水可以直接排向压缩机仓内的接水盘或者是直接排向冷藏间室的冷藏排水孔。
在本申请的一些具体示例中，如图1所示，风道空间30的底壁向下凹入限定出盛水空间32，排水口33位于盛水空间32的最低处。从而使得固定支架3的结构简单，且保证冷凝水可以完全排出盛水空间32。当然可以理解的是，可以在风道空间30的底壁放置接水盘以限定出盛水空间32。
根据本申请的一些实施例，如图1所示，冰箱100还包括用于对制冰蒸发器6进行加热的加热装置8，加热装置8设在风道空间30内。具体而言，当制冰蒸发器6发生结霜现象时，可以利用加热装置8进行加热，以使得制冰蒸发器6发生化霜现象，避免制冰蒸发器6因结霜现象而影响制冰效果。具体地，加热装置8可以为电加热器。在图1所示的具体示例中，加热装置8设在制冰蒸发器6的下部。
根据本申请实施例的冰箱100100，由于制冰蒸发器6设在发泡层内，因此加热装 置8远离制冰机设置，加热装置8可以远离制冰机的制冰室和储冰桶设置，减少了加热装置8对制冰蒸发器6加热除霜时往制冰室内的传热，特别是往储冰桶内的传热，避免了储冰桶内的冰块在制冰蒸发器6加热除霜时发生融化现象。
根据本申请实施例的冰箱100的其他构成例如压缩机和温控部分等以及操作对于本领域普通技术人员而言都是已知的，这里不再详细描述。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示意性实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本申请的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
尽管已经示出和描述了本申请的实施例，本领域的普通技术人员可以理解：在不脱离本申请的原理和宗旨的情况下可以对这些实施例进行多种变化、修改、替换和变型，本申请的范围由权利要求及其等同物限定。
