冰箱及其制造方法 技术领域
本发明涉及一种冰箱，尤其涉及一种具有横梁的冰箱及其制造方法。
背景技术
冰箱作为一种可使食物或其他物品保持恒定低温冷态的容器已成为现代家庭不可缺少家用电器之一。冰箱通常包括上下分离设置的冷藏室和冷冻室，以用于分别存放需在不同温度下保存的物品。为了方便部分物品的放置，冷藏室和冷冻室通常会设置有抽屉，上下相邻的抽屉间设置有支撑抽屉的横梁。该横梁内部通常填充有泡沫或海绵等填充物，并通过两侧延伸出卡持片与冰箱的内胆相定位。传统的该种横梁要先进行泡沫填充，然后再安装到冰箱上，组装过程较为麻烦；并且由于泡沫的导热率较大，横梁内部的泡沫或海绵的组装精度较低、密封性能较差，以及横梁两侧与内胆安装后存在缝隙且稳定度较低等，均容易影响冰箱的整体保温性能。
因此，有必要提供一种改进的冰箱及其制造方法以解决上述问题。

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。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。
图1至图6示出了本发明冰箱的一较佳实施方式。本发明冰箱包括内胆1、围设在内胆1外侧的冰箱外壳(图中未示出)、固定在内胆1上的横梁2、填充在内胆1与冰箱外壳之间以及横梁2内侧的发泡料(图中未示出)。
如图1及图3所示，内胆1具有左右相对设置的两个侧壁11、连接两个侧壁11下端的底壁12、以及连接两个侧壁11和底壁12的后壁13。在本发明中，左右方向对应人体朝向冰箱的内胆1的开口处站立时的左右方向，上下方向也为与之对应的上下方向，内胆1开口处为前、后壁13处为后。
侧壁11上靠近开口的位置处设置有左右贯通侧壁11的插接口111，并且在本实施方式中，两个侧壁11上均设置有插接口111。在替代性实施方式中，也可仅在一个侧壁11上设置插接口111。此外，两个侧壁11的前侧缘还分别向后凹设有一定位槽112。定位槽112与插接口111前后对应。
如图1至图4所示，横梁2固定在内胆1的前侧，并具有本体21及自本体21向外延伸穿入插接口111的插接部22。在本实施方式中，横梁2由沿前后方向相互扣持的第一横梁3和第二横梁4组成。
如图1至图5所示，在本实施方式中，第一横梁3具有第一本体31、自第一本体31的一端前侧向外延伸的定位片32、以及自第一本体31的另一端前侧向外延伸的抵持片33。定位片32和抵持片33分别固定在内胆1前侧的两个定位槽112内。其中，抵持片33成对设置，并沿上下方向相互间隔，以分别抵持在定位槽12的上下内壁上，从而将横梁2定位在内胆1上。
第二横梁4具有与第一本体31相扣持的第二本体41及自第二本体41两端分别向外延伸的两个前述插接部22。该两个插接部22分别对应穿过内胆1的两个侧壁11上的插接口111。
第一本体31和第二本体41相互扣持形成横梁2的本体21。
如图4至图6所示，具体来说，第一本体31具有第一前壁311、自第一前壁311左右两端分别向第二本体41方向延伸的两个第一端壁312、自第一前壁311的上下两端分别向第二本体41方向延伸的第一顶壁313和第一底壁314。第一前壁311、两个第一端壁312、第一顶壁313和第一底壁314之间形成收容发泡料的第一注料腔310。定位片32和抵持片33分别自两个第一端壁312向外延伸形成。
第一顶壁313和第一底壁314靠近第二本体41的一侧分别形成有上下相对的第一子壁315以及位于上下相对的第一子壁315之间的固持槽316。固持槽316朝向第二本体41方向开放设置。
第一顶壁313和第一底壁314中与第一注料腔310相邻的第一子壁315上分别凹设有多个间隔设置的扣持槽3151，扣持槽3151朝向固持槽316内开放。在本实施方式中，扣持槽3151贯穿第一子壁315。
如图1至图5所示，第一本体31的第一顶壁313两端还分别设有向上延伸的限位突起317。限位突起317抵持在内胆1的两个侧壁11内侧，以防止横梁2在安装后左右晃动。
如图4至图6所示，第二本体41对应第一本体31设置有第二后壁411、自第二后壁411左右两端分别向第一本体31方向延伸的两个第二端壁412、以及自第二后壁411的上下两端分别向第一本体31方向延伸的第二顶壁413和第二底壁414。第二后壁411、两个第二端壁412、第二顶壁413和第二底壁414之间形成收容发泡料的第二注料腔410。
第二顶壁413和第二底壁414靠近第一本体31的一侧分别收容在第一顶壁313和第一底壁314的固持槽316内，并且第二顶壁413和第二底壁414分别向内突设有多个扣持块417，扣持块417与第一子壁315上的扣持槽316相扣持，以将第一本体31和第二本体41固定在一起。在第一本体31和第二本体41相互扣合后，第一注料腔310和第二注料腔410相互连通而形成横梁2的注料腔。
如图1至图5所示，横梁2上的插接部22自第二端壁412向外延伸形成，并形成有向插接口111外侧暴露且与注料腔连通的注料口221。注料口221向插接口111外侧暴露，即意味着注料口221暴露于内胆侧壁11的外侧。在进行发泡料的填充时，发泡料通过注料口221进入至注料腔内并填充注料腔和注料口221。在本实施方式中，插接部22穿出插接口111，意味着注料口221延伸到内胆侧壁11的外侧。注料口221朝向内胆1开口方向开放设置，插接部22除注料口221之外其余的部分均形成有挡板222。
此外，在本实施方式中，横梁2由沿前后方向相互扣持的第一横梁3和第二横梁4组成；当然，横梁2也可为一体连接的整体式结构，此时，定位片32、抵持片33及限位突起317均自一体连接本体21上突伸形成，并与内胆1的侧壁11相配合以将横梁2定位在内胆1上。
本发明冰箱在成型时，先将横梁2安装在内胆1上，使得插接部22自插接口111伸出至内胆1外侧，并通过插接部22、定位片32和抵持片33分别与内胆1的插接口111和定位槽112相配合，限位突起317抵持内胆1的侧壁11内侧等结构而使横梁2定位在内胆1上，并且在发泡料填充时不会晃动；然后再进行发泡料的填充，由此使得内胆1与冰箱外壳之间的发泡料和横梁2的注料腔和注料口221内的发泡料能够一次性填充完成，并且通过发泡料将横梁2和内胆1稳固连接在一起，提高横梁2的强度和稳定性。
由以上可知，本发明还涉及一种冰箱的制造方法，其包括以下步骤：
提供上述内胆1；
提供上述横梁2；
将横梁2固定在内胆1上，使本体21位于内胆1的两个侧壁11之间，插接部22穿入插接口111而使注料口221向插接口111外侧暴露；
提供一冰箱外壳并将冰箱外壳安装在内胆1外围；
提供发泡料并进行发泡料的填充，使发泡料填充至冰箱外壳与内胆1之间并自注料口221填充至注料腔和注料口221内。
综上所述，本发明通过在横梁2的两侧设置穿入内胆1侧壁11上插接口111的插接部22，并在插接部22设置与横梁2内侧的注料腔连通的注料口221，使得本发明冰箱在进行发泡料的填充时，可将发泡料通过注料口221进入至注料腔内并填充注料腔和注料口221，从而使得横梁2与冰箱内胆1外侧的发泡同时进行，成型方便；并且通过利用发泡料填满横梁2的注料腔，使得冰箱的保温性能和密封效果较好；此外，发泡料还可将横梁2与内胆1稳固地连接在一起，使得横梁2的强度及稳定性得以进一步提高。
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。
