具体实施方式
下面参考附图来描述根据本发明实施例的冰箱。
如图1～6所示，本发明一实施例的冰箱100，包括：箱体10，门体，制冷***以及风道***。需要说明的是，虽然本说明书中以附图冰箱为例进行了说明，但本发明并不限于此，本发明还可以应用于其他结构的冰箱。
箱体10定义冰箱100的外部边界，其限定有用于存储食品的存储间室，具体地，所述存储间室包括用于冷藏食品的冷藏室20、用于冷冻食品的冷冻室、以及变温室等。
在本实施例中，冷藏室20设置于所述冷冻室的上方。冷藏室20具有内胆，定义靠近冷藏室20的存储空间的一侧为内，定义远离冷藏室20的存储空间的一侧为外，所述内胆包括相对设置的内表面和外表面，所述内表面围成冷藏室20的所述存储空间，所述外表面远离冷藏室20的所述存储空间设置。另外，所述内胆还包括上下相对设置的顶壁和底壁、左右相对设置的两侧壁202、以及后壁201。
所述门体活动配合至箱体10的前方，以用于开闭所述存储间室。具体地，所述门体包括冷藏门体31和冷冻门体32：冷藏门体31铰接于箱体10上，以用于开启和关闭冷藏 室20；冷冻门体32滑动设置于箱体10前方，以用于开启和关闭所述冷冻室。
在本实施例中，冷藏门体31上限定有制冰间室40，制冰间室40具体可设置于冷藏门体31的内侧(也即当冷藏门体31关闭时的后部)，其内布设有制冰机、冰盒等构件，水在制冰间室40内可被制作成冰块；冷藏门体31的外侧还设置有分配器90，分配器90用于在保持冷藏门体31关闭的情况下即可从冰箱100的外部取出制冰间室40内的冰块。
在本实施例中，冰箱100设置为三***冰箱，具体地，所述制冷***包括冷冻蒸发器、冷藏蒸发器、制冰蒸发器51。其中，所述冷冻蒸发器设置于所述冷冻室处并用于为所述冷冻室提供冷量，以使所述冷冻室维持其冷冻存储温度；所述冷藏蒸发器设置于冷藏室20处并用于为冷藏室20提供冷量，以使冷藏室20维持其冷藏存储温度；制冰蒸发器51设置于冷藏室20处并用于为制冰间室40提供冷量，以满足制冰间室40的制冰需求。这样，所述冷冻室、冷藏室20、制冰间室40分别由相应的独立蒸发器提供冷量，避免共用蒸发器造成的结霜严重问题，而且制冰间室40的供冷时机可独立控制而不受到所述冷冻室和冷藏室20供冷的影响，便于使用且节能降耗。
所述风道***包括连通制冰间室40以便于形成循环风路径的制冰风道***，所述制冰风道***包括制冰蒸发器间室61、制冰送风道62以及制冰回风道63。其中，制冰蒸发器间室61设置于冷藏室20的内胆后壁201处，且其内部容置有制冰蒸发器51；制冰送风道62、制冰回风道63均设置于冷藏室20的内胆侧壁202处，并连通制冰蒸发器间室61和制冰间室40。当需要制作冰块时，流经制冰蒸发器51的制冷剂可与制冰蒸发器间室61内的空气进行冷量交换，以使制冰蒸发器间室61内形成低温空气，而制冰蒸发器间室61内的空气可通过制冰送风道62进入制冰间室40，而后通过制冰回风道3返回制冰蒸发器间室61。
根据本发明实施例的冰箱100，制冰间室40采用独立的蒸发器提供冷量，避免与冷藏室20和所述冷冻室共用蒸发器造成的结霜严重问题，而且制冰间室40的供冷时机可独立控制而不受到所述冷冻室和冷藏室20供冷的影响，便于使用且节能降耗；同时，采用独立的风道***为制冰间室40供风，空气不与冷藏室20、所述冷冻室的空气混杂，有效解决串味问题，使制得的冰块用户食用感受更佳；而且，制冰蒸发器间室61设于冷藏室20的内胆后壁201处，制冰送风道62、制冰回风道63设于冷藏室20的内胆侧壁202处，大大缩短空气流动的路径长度，减小风流的阻力，有效降低能耗损失，提升制冰效率。
进一步地，所述风道***还包括冷藏风道***和冷冻风道***。所述冷藏风道***包括容置所述冷藏蒸发器的冷藏蒸发器间室、连通所述冷藏蒸发器间室和冷藏室20的冷藏 送风道和冷藏回风道，以实现冷风于所述冷藏蒸发器间室、所述冷藏送风道、冷藏室20、所述冷藏回风道之间循环；所述冷冻风道***包括容置所述冷冻蒸发器的冷冻蒸发器间室、连通所述冷冻蒸发器间室和所述冷冻室的冷冻送风道和冷冻回风道，以实现冷风于所述冷冻蒸发器间室、所述冷冻送风道、所述冷冻室、所述冷冻回风道之间循环。
在本实施例中，所述制冰风道***设置于冷藏室20的内胆外侧，也就是说，所述制冰风道***设置于冷藏室20的所述内胆的所述外表面与箱体10之间。具体地，制冰蒸发器间室61设置于冷藏室20的内胆后壁201的外侧，也即设置于内胆后壁201处所述外表面与箱体10之间，也即设置于内胆后壁201的后方；制冰送风道62和制冰回风道63设置于冷藏室20的内胆侧壁202的外侧，也即设置于内胆侧壁202处所述外表面与箱体10之间，在图中也即设置于内胆侧壁202的左方。这样，一方面可增加冷藏室20内的美观与整洁度，另一方面可使制冰送风道62和制冰回风道63的布局不受到冷藏室20内搁架/抽屉等的影响，进而制冰送风道62和制冰回风道63设置为从制冰蒸发器间室61到制冰间室40呈大致直线延伸，大大减小冷量损耗。
进一步地，冷藏门体31包括门体本体、安装于所述门体本体的内壁的门封311、安装于所述门体本体的内壁的门衬312、以及活动连接于门衬312上的制冰间室门体313。当冷藏门体31开启时，通过开闭制冰间室门体313，可开闭制冰间室40。在本实施例中，制冰间室40形成于冷藏门体31的内侧，且所述门体本体的内壁、门衬312、制冰间室门体313共同限定出制冰间室40的边界。
制冰间室40包括形成于门衬312上的第一开口41和第二开口42；相对应的，制冰送风道62具有形成于内胆侧壁202处的送风口621，制冰回风道63具有形成于内胆侧壁202处的回风口631。当冷藏门体31关闭时，第一开口41和送风口621位置相对应且彼此相连通，从而使制冰送风道62与制冰间室40相连通，第二开口42和回风口631位置相对应且彼此相连通，从而使制冰回风道63与制冰间室40相连通；当冷藏门体31开启时，第一开口41和送风口621分开，同时，第二开口42和回风口631分开。
优选地，冰箱100还包括加热丝91，加热丝91设置于送风口621、回风口631周围，当加热丝91通电时可产热，从而对送风口621、回风口631进行化霜，从而避免霜在送风口621、回风口631周围凝结。
进一步地，内胆侧壁202包括胆本体、以及盖板2021。具体地，所述胆本体具有凹槽2022，该凹槽2022设置为自所述胆本体的内表面向外凹陷，加热丝91布设于凹槽2022内；盖板2021可拆卸地组装在凹槽2022内，以用于遮蔽加热丝91，达到美观效果，且 保护加热丝91不受损伤。
另外，盖板2021可设置为导热材质，这样，当加热丝91通电产热时，可同时对第一开口41、第二开口42处进行化霜，提升化霜效率。
盖板2021包括相对靠近凹槽2022设置的外侧面以及相对靠近冷藏室20的存储空间设置的内侧面。优选地，当盖板2021组装于凹槽2022内时，盖板2021的所述内侧面与所述胆本体的内表面相齐平，也就是，从冷藏室20内看，盖板2021的所述内侧面与所述胆本体的内表面大致上共平面。
进一步地，在本实施例中，冰箱100还包括两个密封件80，分别设置于第一开口41和第二开口42处。当冷藏门体31关闭时，密封件80抵接于内胆侧壁202以使第一开口41与送风口621、第二开口42与回风口631分别密封连通，从而避免冷量从第一开口41与送风口621之间、或者第二开口42与回风口631之间流失入冷藏室20内，保证制冰效率，而且还可避免冷藏室20内的空气进入制冰间室40内而造成串味。
本实施例中，密封件80通过卡接组装于门衬312上。具体地，门衬312具有分别环绕第一开口41和第二开口42设置的第一卡接部3121；密封件80包括密封件本体82及连接于密封件本体82的第二卡接部81。其中，第一卡接部3121和第二卡接部81可沿第一方向X彼此插接，以使所述密封件80组装于门衬312上。这种组装方式简单方便，节省组装时间。
如本实施例，第一卡接部3121可设置为凹设在门衬312的卡接槽，对应的，第二卡接部81凸伸出密封件本体82设置，组装时，第二卡接部81配合至所述卡接槽内。当然，在变换的实施例中，第一卡接部3121可设置为凸伸出门衬312的凸起，相对应的，第二卡接部81凹设于密封件本体82上。
进一步地，第二卡接部81和所述卡接槽之间还设置有引导结构。具体地，所述引导结构包括设置于第二卡接部81上的第一引导斜面811、以及设置于所述卡接槽上的第二引导斜面31211，当第二卡接部81向所述卡接槽内组装时，第一引导斜面811和第二引导斜面31211可引导第二卡接部81沿所述第一方向X运动以顺利进入所述卡接槽内。
第二卡接部81和所述卡接槽之间还设置有锁止结构。具体地，所述锁止结构包括设置于第二卡接部81上的第一抵持面812、以及设置于所述卡接槽上的第二抵持面31212。当第二卡接部81配合至所述卡接槽内后，若施加于密封件80上一沿第二方向的拉力，所述第二方向与所述第一方向相反，第二抵持面31212可施加于第一抵持面812一沿所述第二方向的抵持力，从而限制第二卡接部81脱出所述卡接槽外。
另外，在本实施例中，密封件本体82围成一中部开孔801，当密封件80组装至门衬312上的第一开口41处时，开孔801与第一开口41相对应，从而便于空气从第一开口41流入；当密封件80组装至门衬312上的第二开口42处时，开孔801与第二开口42相对应，从而便于空气从第二开口42流出。
密封件本体82包括相对设置的固定端821及活动端822。其中，固定端821连接于第二卡接部81并远离开孔801设置，活动端822围成开孔801。当冷藏门体31关闭时，密封件本体82抵持内胆侧壁202且活动端822可脱离其初始位置，从而保证密封性。这样，密封件本体82可于门衬312和内胆侧壁202之间过盈配合，通过活动端822的运动而增强密封性，同时避免密封件80长期受挤压而损坏；而且活动端822向开孔801处形变，进一步保证冷气***露。
优选地，在本实施例中，密封件本体82自固定端821呈弧形向活动端822延伸，密封件本体82设置为半球形。当然，在替代的实施例中，密封件本体82还可呈其他方式延伸。
与现有技术相比，本实施例的冰箱100具有以下有益效果：1)制冰间室40采用独立的蒸发器提供冷量，避免与冷藏室20和所述冷冻室共用蒸发器造成的结霜严重问题，而且制冰间室40的供冷时机可独立控制而不受到所述冷冻室和冷藏室20供冷的影响，便于使用且节能降耗；2)采用独立的风道***为制冰间室40供风，空气不与冷藏室20、所述冷冻室的空气混杂，有效解决串味问题，使制得的冰块用户食用感受更佳；3)制冰蒸发器间室61设于冷藏室20的内胆后壁201处，制冰送风道62、制冰回风道63设于冷藏室20的内胆侧壁202处，大大缩短空气流动的路径长度，减小风流的阻力，有效降低能耗损失，提升制冰效率；4)加热丝91被盖板2021所遮蔽，避免损坏几率，且化霜效率高；5)密封件的组装结构简便，且本身结构稳定性强。
