Description

用于制冷设备的箱体及制冷设备 技术领域
本发明涉及及制冷技术领域，尤其涉及一种用于制冷设备的箱体及制冷设备。
背景技术
由于对较大制冷间室的需求，有些制冷设备省去了制冷间室内中梁的使用。但是没有中梁的制冷设备在使用过程中，制冷设备的内部冷冻温度达到零下18℃以下，而制冷设备外面的温度基本上在20℃，夏季时甚至达到35℃以上，箱体内侧的内胆为塑料板材，内胆和发泡料受冷收缩，而外侧钢板受热膨胀，二者的受热膨胀冷缩的形变量和形变方向不同就会造成箱体的侧部内凹的现象。目前有厂家采用在制冷设备内部增加加强板的解决方案，但是箱体内增加加强板会带来生产成本的增加，而且会影响制冷设备内胆的优化设计。
有鉴于此，有必要对现有的箱体进行改进，以解决上述技术问题。

具体实施方式
为了使本领域的技术人员更好地理解本发明中的技术方案，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、 完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都应当属于本发明保护的范围。
需要说明的是，术语“上”、“下”等指示的方位或位置关系为基于辅图所示的方位或位置关系，仅是为了便于简化描述本发明，而不是指示或暗示所指的装置必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明保护范围的限制。具体地，在本发明中，以用户的操作面为前面，以朝向地面的方向为下，相反地，远离地面的方向为上，其他表示方位的描述均是以“上”、“下”为基准定义的。
在本发明的各个图示中，为了便于图示，结构或部分的某些尺寸会相对于其它结构部分夸大，因此，仅用于图示本发明主题的基本结构。
一种用于制冷设备的箱体，如图1至图5所示，包括内胆(未图示)、位于所述内胆外侧的外壳10，本发明通过改变外壳的设计，来解决箱体内外温差较大时，外壳10遇热膨胀、内胆遇冷收缩产生的形变量和形变方向不同进而出现的箱体变形的问题。
具体地，如图1所示，所述外壳10上设有沿所述外壳10的高度方向分布的至少一个阻断槽20；所述阻断槽20沿所述外壳10的宽度方向延伸，所述阻断槽20沿内外方向贯穿所述外壳10，所述阻断槽20可有效地阻断所述外壳10遇热膨胀产生的形变，使得所述外壳10和内胆的形变差异变小，避免箱体出现向内凹陷的问题，进而提升制冷设备的使 用寿命及用户体验。
具体地，使用过程中，箱体形变最大出现的区域位于其高度方向的中间位置处，本发明通过将所述阻断槽20设置在所述外壳20高度方向上的中间区域，使得所述阻断槽20的位置与制冷设备的箱体形变量最大的位置相匹配，以能最大程度地避免所述外壳10产生的形变。
在一些实施例中，所述外壳10上也可以设有两个所述阻断槽20，两个所述阻断槽20沿所述外壳10高度方向均匀分布在所述外壳10上，两个所述阻断槽20共同解决所述外壳10遇热膨胀所导致的形变问题。
进一步地，所述外壳10具有一对侧壁11，由于所述侧壁11与箱体的开口相邻，所述侧壁容易出现向内凹陷的问题，所以，所述阻断槽20位于所述外壳10的侧壁11上。
作为本发明一个较佳实施例，如图3、图4所示，所述阻断槽20前端在所述外壳10的高度方向上的宽度大于后端在外壳10高度方向上的宽度。由于箱体前端设有门体，所述箱体靠近门体的前端的支撑强度小于箱体的后端，因此，外壳10的前端预热膨胀所导致的形变量比外壳10的后端大，本实施例通过所述阻断槽20两端设计不同的尺寸，以解决外壳10的前端形变量大于外壳10后端形变量的问题，提升外壳10的适应性。
当然，所述阻断槽20的前端至所述外壳10前端的距离小于所述阻断槽20的后端至所述外壳10后端的距离，也即所述阻断槽20设置于所述侧壁上靠前的位置处，也可以解决外壳10前端形变量大于外壳10后端形变量的问题。
一般来说，所述阻断槽20在所述外壳10高度方向上的尺寸由内胆的形变量和所述外壳10的形变量共同决定，例如，箱体内胆内缩形变量为X，外壳10膨胀形变量为Y,由于外壳10和内胆的形变方向相反，所以，箱体的总的形变量为X+Y，阻断槽20的宽度至少为X+Y才能抵消外壳10和内胆之间总的形变量。
进一步地，所述阻断槽20包括第一阻断槽21，所述第一阻断槽21位于侧壁的中间区域，以能调节所述外壳10上下两部分产生的形变。
优选地，所述第一阻断槽在所述外壳10高度方向上的前后宽度一致，且所述第一阻断槽21在所述外壳10的高度方向上的内径尺寸范围为2mm～9mm，以使得所述第一阻断槽20更好地阻断所述外壳10的形变。本实施例中，所述第一阻断槽21的宽度在结合材料的性质和工作温度得到的最佳的宽度范围，使得外壳10和内胆的形变差异变小，有效地解决制冷设备的箱体变形的问题。
所述第一阻断槽21在所述外壳10的宽度方向上的内径尺寸介于所述外壳10宽度的三分之一至三分之二之间，所述第一阻断槽21合适的尺寸既可以阻断所述外壳10受热膨胀导致的在其宽度方向上的形变，又不影响所述外壳10整体的结构强度。
作为本发明另一个较佳实施例，如图2所示，所述阻断槽20还包括位于所述第一阻断槽21上方和/或下方的第二阻断槽22，所述第二阻断槽22的内径尺寸小于所述第一阻断槽20的内径尺寸，所述第二阻断槽22用来辅助所述第一阻断槽21来阻断所述外壳由于遇热膨胀导致形变的问题。
本实施例中，在所述外壳10的高度方向上，所述外壳10上设有两个第二阻断槽22。在制冷设备较高的情况下，所述第一阻断槽21到外壳10上端或者所述第一阻断槽21到外壳10下端距离较大，也就是在所述第一阻断槽21的上方区域或下方区域仍然存在外壳10产生形变的情况，本实施例利用第二阻断槽22来进一步阻断或调整所述第一阻断槽21上方和下方区域因热膨胀所产生的形变。
进一步地，所述第二阻断槽22距所述侧壁11的前端的距离小于所述第二阻断槽22距所述侧壁11的后端的距离。也就是所述第二阻断槽22更靠近侧壁11的前端，使得侧壁11前端部分在热胀时的形变同时被第一阻断槽21和第二阻断槽22阻断，而侧壁11的后端部分在热胀时的形变被第一阻断槽21阻断，以此来解决靠近制冷设备门体的外壳10前端形变量大于外壳10后端形变量的问题。
在制冷设备较高的情况下，在所述外壳的高度方向上，所述外壳10容易遇热产生形变的区域也较大，优选地，其中一个所述第二阻断槽22位于所述第一阻断槽21到所述外壳10上端的中间，另一个所述第二阻断槽22位于所述第一阻断槽21到所述外壳10下端的中间，使得所述第一阻断槽21和所述第二阻断槽22处于所述外壳10出现形变的区域，所述第二阻断槽22辅助配合所述第一阻断槽21将外壳10的形变阻断，以解决较高制冷设备的外壳10产生形变较大的问题。
优选地，在所述外壳10的高度方向上，所述第二阻断槽22的内径尺寸范围为1mm-3mm，在所述外壳10的宽度方向上，所述第二阻断槽22的内径尺寸不大于所述外壳10宽度的二分之一，以确保所述第二阻断槽 22不影响所述外壳10的整体强度。
可以理解的是，在所述第一阻断槽21的上方或者下方只设置一个所述第二阻断槽22或者在所述第一阻断槽21的上方、下方均设置多个第二阻断槽22，同样能实现相同的技术问题，均在本发明的保护范围之内。
在一些具体的实施过程中，所述第一阻断槽21和/或第二阻断槽22的在所述外壳的高度方向上的前后宽度一致，也可以是第一阻断槽21和/或第二阻断槽22所述外壳的高度方向上的相邻侧壁前端的宽度大于相邻后端的宽度，均在本实施例的保护范围之内。
进一步地，如图5所示，所述外壳10还包括用于遮盖所述阻断槽20的盖体40，所述盖体40包括用于遮蔽所述阻断槽20的基座41、自所述基座41向内突伸以能够与所述阻断槽20相卡接的卡接结构42。利用盖体40遮盖所述阻断槽20，一方面，所述外壳10的外观比较整齐，且所述阻断槽20处的强度得到了补偿，另一方面，用来保护所述外壳10内的结构，提升制冷设备的美观性和安全性。
具体地，所述卡接结构42包括连接所述基座41的一对连接部421、分别连接于一对所述连接部421远离所述基座41的一端且相对向外凸伸的一对限位部422、连接于每一所述限位部422远离所述连接部421的一端的插接部423，在所述阻断槽20的长度或者宽度方向上，一对所述限位部422最大处的尺寸大于所述阻断槽20的内径尺寸。所述基座41、连接部421和限位部422之间形成卡槽424，相邻所述阻断槽20的外壳10端部被限制在所述卡槽424内，将所述盖体40固定在所述外壳10上。
可以理解的是，所述限位部422的凸伸方向可以沿着所述阻断槽20 的宽度方向也可以沿着所述阻断槽20的长度方向，均能实现对所述盖体40的固定，为了所述卡接结构42与外壳10更好地配合，所述限位部422的凸伸方向优选为沿着所述阻断槽20的长度方向。
可以理解的是，所述基座41的大小及具体形状和与之相匹配的第一阻断槽21和第二阻断槽22内径尺寸和形状相匹配，所述限位部422最大处的尺寸大于所述第一阻断槽21和第二阻断槽22的内径尺寸，以更好的实现对盖体40的固定。
在所述外壳10安装在内胆的外侧形成箱体的过程中，将所述盖体40预安装在所述外壳10上，再进行发泡，使得所述卡接结构42处于发泡层内，对盖体40做进一步地固定，同时，所述卡接结构42特有的结构形态可以承受外壳10产生形变时对外壳10内部发泡层的挤压，对箱体整体的形变起到缓冲的作用。
本发明还涉及一种制冷设备，其中，所述制冷设备包括上述的箱体、打开或闭合所述箱体的门体。所述阻断槽20设于所述箱体侧部的外壳10上，所述阻断槽20可有效地阻断所述外壳10遇热膨胀产生的形变，使得所述外壳10和内胆的形变差异变小，避免制冷设备的箱体出现向内凹陷的问题，进而提升制冷设备的使用寿命及用户体验。
综上所述，本发明用于制冷设备的箱体，在外壳10高度方向上设置至少一个沿内外方向贯穿所述外壳10的阻断槽20，通过利用所述阻断槽20来阻断所述外壳10遇热膨胀产生的形变，使得所述外壳10和内胆的形变差异变小，避免箱体出现向内凹陷的问题，进而提升制冷设备的使用寿命及用户体验
