Description

一种具有对开门的冰箱 技术领域
本发明涉及冰箱的制造领域，特别涉及一种具有对开门的冰箱的竖梁电热丝的电连接结构。
背景技术
现有具有对开门的冰箱的左、右两个门体之间的间隙会造成冷量的流失，业内普遍采用的是安装至一侧门体且可翻转的竖梁以实现两侧门体的搭接与密封。但竖梁本身的厚度较小，其表面温度相对较低；并且竖梁位于左、右门体之间，空气流通性较差，因此，竖梁上容易产生凝露。通常地，会在竖梁的内侧设置一加热部件以解决其表面凝露问题。目前的设计均是通过门体发泡前预装布线，加热部件通过门体内的导线连通电源以完成取电加热。其中，专利CN203443225U公开了一种导线预埋盒用以收纳竖梁加热导线，避免门体中的导线受发泡工艺的影响。但，并未解决门体布线所带来的工艺复杂、成本增加的问题，且门体的反复开启/关闭亦会影响线束的稳定性。
鉴于此，有必要提供一种新的具有对开门的冰箱。
发明内容
本发明目的在于提供一种具有对开门的冰箱，无需对门体进行预装布线，简化工艺，提高效率。

作为本发明的进一步改进，所述第一导电端子设置于所述导向柱朝向所述导向槽的一端；所述第二导电端子设置于所述导向槽的末端。
作为本发明的进一步改进，所述导向柱包括主体部及自主体部朝向所述导向槽的一端形成的呈弧形的端部，所述第一导电端子设置于所述端部与主体部的连接处。
作为本发明的进一步改进，所述导向槽形成有弯折延伸的侧壁，所述第二导电端子突伸设置于所述侧壁上。
作为本发明的进一步改进，所述导向槽还具有自开口处朝向两侧延伸形成的导引部。
作为本发明的进一步改进，所述导向槽设置于所述竖梁的上端面，所述竖梁的内侧还设有电热丝，所述电热丝与第二导电端子电性连接；所述导向柱设置于所述箱体的上方开口处，所述第一导电端子与所述冰箱的电源端电连接。
作为本发明的进一步改进，所述箱体的上方开口处还设有一基座，所述导向柱固定于所述基座上。
作为本发明的进一步改进，所述第一导电端子与所述冰箱的电源端之间还连接设置有一开关，所述开关设置为在第一导电端子与第二导电端子相接触时导通，并在第一导电端子与第二导电端子相分离时断开。
