Description

箱体及冰箱 技术领域
本发明涉及制冷装置领域，尤其涉及一种能够防止因发泡料热胀冷缩导致外壳变形的箱体及冰箱。

冰箱一般包括间隔设置的冷藏室以及冷冻室，具体地，所述冰箱包括箱体、与所述箱体围设形成制冷间室的门体，所述箱体包括外壳、设于所述外壳内且间隔设置的冷藏内胆以及冷冻内胆、设于所述冷藏内胆与所述冷冻内胆外周且位于所述外壳内的保温层，所述冷藏内胆与所述门体围设形成所述冷藏室，所述冷冻内胆与所述门体围设形成所述冷冻室。
所述冷冻内胆与所述外壳之间的间隙大于所述冷藏内胆与所述外壳之间的间隙，即，所述冷冻内胆与所述外壳之间的保温层的厚度大于所述冷藏内胆与所述外壳之间的保温层的厚度，以保证所述冷冻室的保温效果。
可以看出，所述保温层的厚度在所述冷冻内胆与所述冷藏内胆之间存在较大的差异，箱体在发泡时，发泡料热胀导致外壳膨胀，脱模后，温度冷却，发泡料收缩，因其厚度不同会导致收缩不一致，或者在冰箱正常工作时，因为冷藏室与冷冻室的制冷温度不同，也会使保温层收缩不一致，导致所述外壳上与所述冷冻内胆与所述冷藏内胆之间的间隔区相对应的位置处易出现凹坑、波浪纹等变形的情况，造成所述冰箱的外观较差，影响产品质量和用户体验。
为解决上述问题，现有的部分箱体，在外壳上与所述间隔区相对应的位置处贴附加强铁以加强所述外壳的强度，避免所述外壳变形，但是，设置加强铁的成本较高，且，一般采用双面胶将加强铁贴附至外壳上，有掉落的风险。
有鉴于此，有必要提供一种新的箱体及冰箱以解决上述问题。
发明内容
本发明的目的在于提供一种能够防止因发泡料热胀冷缩导致外壳变形的箱体及冰箱。
为实现上述发明目的，本发明采用如下技术方案：一种箱体，包括外壳、于所述外壳内间隔设置的两个内胆，两个所述内胆与所述外壳的间隙不同；所述箱体还包括贴设于所述外壳内侧的第一应力消除件，所述第一应力消除件位于所述外壳与两个所述内胆之间的间隔区相对应的位置处。

作为本发明进一步改进的技术方案，所述箱体还包括开口、位于所述开口处且位于两个所述内胆之间的分割梁，所述第一应力消除件的前端与所述分割梁之间具有间隙。
作为本发明进一步改进的技术方案，所述外壳包括后壁、自所述后壁向前延伸的两个侧壁；所述箱体还包括于所述间隔区连接两个所述内胆的第二应力消除件，所述第二应力消除件设于所述内胆上与所述侧壁相对应的一侧。
为实现上述发明目的，本发明还提供一种冰箱，包括上述的箱体。
本发明的有益效果是：本发明中的箱体，在外壳内侧与两个所述内胆之间的间隔区相对应的位置处贴设第一应力消除件，在发泡形成保温层后，所述第一应力消除件位于所述保温层与所述外壳之间，在所述保温层发生热胀冷缩时，所述第一应力消除件能够缓冲两个所述内胆外周的保温层对外壳产生的应力差，从而能够防止所述外壳变形。
附图说明
图1是本发明中的箱体的结构示意图。
图2是图1所示的箱体的俯视图。
图3是图2中A-A向的剖视图。
具体实施方式
以下将结合附图所示的各实施方式对本发明进行详细描述，请参照图1-图3所示，为本发明的较佳实施方式。但应当说明的是，这些实施方式并非对本发明的限制，本领域普通技术人员根据这些实施方式所作的功能、方法上的等效变换或替代，均属于本发明的保护范围之内。
请参图1-图3所示，本发明提供一种箱体100，包括外壳1、于所述外壳1内间隔设置的两个内胆2，两个所述内胆2与所述外壳1的间隙不同。所述外壳1具有开口，两个所述内胆2位于所述开口处的边缘与所述外壳1密封连接，所述外壳1与两个所述内胆2之间形成发泡腔，通过向所述发泡腔内注入液态的发泡料，液态的发泡料固化形成保温层，同时通过所述保温层将所述外壳1与两个所述内胆2坚固的连接在一起。
具体地，两个所述内胆2中的一个为冷藏内胆21，另一个为冷冻内胆22，所述冷藏内胆21与所述外壳1之间的间隙小于所述冷冻内胆22与所述外壳1之间的间隙，从而，形成的所述冷冻内胆22外周的保温层的厚度大于所述冷藏内胆21外周的保温层的厚度，即，所 述内胆2设定的制冷温度越低，其外周的保温层的厚度越厚，从而，能够达到相应的保温效果。
可以理解的是，所述冷冻内胆22对应的保温层的厚度与所述冷藏内胆21对应的保温层的厚度不同，在保温层发生热胀冷缩时，它们对对应的外壳1产生的应力也不同，即，对应的外壳1产生的应变不同，就会使所述外壳1与两个所述内胆2之间的间隔区相对应的位置处产生变形，如波浪纹或者凹坑不平。
进一步地，所述箱体100还包括贴设于所述外壳1内侧的第一应力消除件3，所述第一应力消除件3位于所述外壳1与两个所述内胆2之间的间隔区相对应的位置处，可以理解的是，在发泡形成保温层后，所述第一应力消除件3位于所述保温层与所述外壳1之间，在所述保温层发生热胀冷缩时，所述第一应力消除件3能够缓冲两个所述内胆2外周的保温层对外壳1产生的应力差，从而能够防止所述外壳1变形。
本实施方式中，所述第一应力消除件3为软质发泡件，在发泡形成保温层后，所述第一应力消除件3能够与保温层紧密结合在一起，防止所述第一应力消除件3与所述保温层分层，从而防止因所述保温层冷缩，导致所述外壳1与所述第一应力消除件3对应的位置处出现空鼓，同时，在所述保温层发生热胀冷缩时，软质的所述第一应力消除件3能够缓冲两个所述内胆2外周的保温层对所述外壳1产生的应力差，从而能够防止所述外壳1变形。当然，并不以此为限，所述第一应力消除件3也可以采用软质胶带直接贴附于外壳1的内侧。
具体地，在所述第一应力消除件3为软质发泡件的实施方式中，所述第一消除件可以选用发泡PE件、发泡PP件、发泡PVC件、发泡三聚氰胺泡沫件、发泡橡胶件等。
可以理解的是，在所述第一应力消除件3为软质发泡件时，可以采用双面胶或者胶水等将其贴附于所述外壳1的内侧。
进一步地，所述第一应力消除件3的厚度为0.1mm～5mm，所述第一应力消除件3的导热系数高于形成保温层的发泡料的导热系数，即，所述第一应力消除件3的保温性能低于形成保温层的发泡料的保温性能，故，限制所述第一应力消除件3的厚度，能够保证所述箱体100的保温性能，防止因所述第一应力消除件3的厚度较厚影响所述箱体100的保温性能。
进一步地，所述第一应力消除件3的熔点大于70℃，可以理解的是，在向所述发泡腔内填充发泡料前，先将所述第一应力消除件3贴附于所述外壳1的内侧，从而，限定所述第一应力消除件3的熔点大于70℃，能够防止温度较高的发泡料接触所述第一应力消除件3导致所述第一应力消除件3熔化。
进一步地，所述第一应力消除件3的密度为10kg/m3～30kg/m3，保证其柔韧性，从而，在所述保温层发生热胀冷缩时，所述第一应力消除件3能够很好地缓冲两个所述内胆2外周的保温层对外壳1产生的应力差，从而能够防止所述外壳1变形。
可以理解的是，若所述第一应力消除件3的密度较大，则其柔韧性较差，达不到要求的缓冲应力差的效果；若所述第一应力消除件3的密度较小，则其较轻且内部的发泡孔很大， 受到保温层的应力时，易产生断裂，导致失效。
进一步地，沿两个所述内胆2的排布方向上，所述第一应力消除件3的两端分别位于所述间隔区的两侧，以使靠近所述间隔区的外壳1也不易产生变形，即，在所述保温层热胀冷缩时，所述第一应力消除件3也能缓冲所述间隔区的保温层与各内胆2保温层因厚度差对所述外壳1产生的应力差，扩大所述第一应力消除件3的作用范围，进一步防止所述外壳1产生变形。
具体地，所述间隔区沿两个所述内胆2的排布方向的宽度为h，所述第一应力消除件3沿所述排布方向的两端距所述间隔区的距离均不小于h/2。
进一步地，所述箱体100还包括位于所述开口处且位于两个所述内胆2之间的分割梁4，所述第一应力消除件3的前端与所述分割梁4之间具有间隙，从而，所述第一应力消除件3不会堵住所述分割梁4上的发泡孔，发泡时，所述发泡料能够顺利流进所述分割梁4内并固化形成保温层，能够保证所述分割梁4的保温效果。
可以理解的是，沿两个所述内胆2的排布方向，所述分割梁4的宽度与所述间隔区的宽度一般设置为一致。
具体地，所述外壳1包括后壁、自所述后壁向前延伸的两个侧壁11，两个所述内胆2沿所述侧壁11的长度延伸方向间隔设置，所述第一应力消除件3设于所述侧壁11上，在所述保温层发生热胀冷缩时，所述第一应力消除件3能够缓冲两个所述内胆2外周的保温层对侧壁11产生的应力差，从而能够防止易被用户看到的所述侧壁11变形；当然，并不以此为限，于其他实施方式中，所述第一应力消除件3也能够同步设置于所述后壁上与所述间隔区相对应的位置处。
进一步地，所述第一应力消除件3沿前后方向的长度与所述侧壁11沿前后方向上的宽度相同，使所述侧壁11沿前后方向的宽度上均不会产生变形，增强用户的使用体验。
于一具体实施方式中，两个所述内胆2沿上下方向间隔设置，可以理解的是，此时，所述两个侧壁11分别指左侧壁以及右侧壁；当然，并不以此为限。
进一步地，所述箱体100还包括于所述间隔区连接两个所述内胆2的第二应力消除件5，所述第二应力消除件5设于所述内胆2上与所述侧壁11相对应的一侧，可以理解的是，所述第二应力消除件5将所述间隔区的保温层与其他的保温层分隔开，从而，所述第二应力消除件5能够缓冲所述间隔区的保温层因两个内胆2内的温度差距较大导致收缩不一致时产生的应力，且所述间隔区的保温层因两个内胆2内的温度差距较大导致收缩不一致时产生的应力也不会传至其他位置处的保温层，从而，进一步防止所述外壳1变形。
所述第二应力消除件5与所述第一应力消除件3除设置位置不同外，其他方面，如所述第二应力消除件5的材料、厚度、密度、熔点、贴附方式等特征均可沿用所述第一应力消除件3的相应特征，于此，不再赘述。
进一步地，本发明还提供一种冰箱，所述冰箱包括上述的箱体100，所述箱体100的结 构已在上文中作了详尽的阐述，于此不再赘述，同时，所述冰箱除上述的箱体100外，其他结构均可沿用现有的冰箱的结构，于此不再赘述。
综上所述，本发明中的箱体100，在外壳1内侧与两个所述内胆2之间的间隔区相对应的位置处贴设第一应力消除件3，在发泡形成保温层后，所述第一应力消除件3位于所述保温层与所述外壳1之间，在所述保温层发生热胀冷缩时，所述第一应力消除件3能够缓冲两个所述内胆2外周的保温层对外壳1产生的应力差，从而能够防止所述外壳1变形。
应当理解，虽然本说明书按照实施方式加以描述，但并非每个实施方式仅包含一个独立的技术方案，说明书的这种叙述方式仅仅是为清楚起见，本领域技术人员应当将说明书作为一个整体，各实施方式中的技术方案也可以经适当组合，形成本领域技术人员可以理解的其他实施方式。
上文所列出的一系列的详细说明仅仅是针对本发明的可行性实施方式的具体说明，它们并非用以限制本发明的保护范围，凡未脱离本发明技艺精神所作的等效实施方式或变更均应包含在本发明的保护范围之内。
