Description

烤箱用门铰链
技术领域
本发明涉及门铰链，更详细地说，涉及一种烤箱用门铰链，使得烤箱门可以向前方打开且完成打开操作后的门高度低于烤箱内部空间的底面。
背景技术
众所周知，门铰链是在门框上实现门的开闭操作的装置，这种门铰链具有两种开闭方式，一种是以门的一侧为起点而向左、右推拉的方式，另一种是以门的上端为起点而向上、下推拉(即，向前拉开的方式)。
此外，上述的另一种门铰链用于家电产品即燃气烤箱或微波炉等的门，举例来说，具有代表性的现有技术为韩国专利厅注册专利公报注册号第10-1480240号(以下简称现有技术)。
所述现有技术公开了一种门向前侧突出的状态下使其向前方卧倒而无干扰地稳定开门的门铰链。
但是，若将现有技术的门铰链结构应用到烤箱，门通过门铰链向前侧突出一定距离的状态下，实现打开操作，从而防止门与门框互相干扰，但现有技术中，门向前方完全卧倒，完成打开操作后，门的高度将高于烤箱的烹饪空间底面，在从烹饪空间取出烹饪好的食物的过程中，频繁发生因盛放食物的托盘碰到所述门而食物掉落等安全事故。
尤其，现有技术的门铰链因采用打开过程中速度逐渐增加的结构，除非另外设置减速装置，否则门开得太快所导致的冲击力会引发噪音及破损。
发明内容
(要解决的技术问题)
因此，用于解决上述问题的本发明的目的在于，提供一种烤箱用门铰链，向前方卧倒而完成打开操作后的门高度低于烤箱的内部空间底面。
(解决问题的手段)
为了实现该目的，本发明提供一种门铰链，其由被固定到烤箱的门框的固定部件以及可旋转地连接到所述固定部件且在被固定到门的状态下对所述门进行打开及关闭操作的操作框架构成，其特征在于，包括铰链支架，该铰链支架包括：板，在贴紧所述操作框架的下端内侧的状态下，通过螺栓连接；及间隙保持件，截面形状为"匚"形，其中心形成空间，前端与所述板的下端结合，其末端在向所述操作框架的下端露出的状态下，通过铰链轴连接到固定部件的下端。
优选地，还设置有连杆装置，其包括：连杆，其末端连接到所述固定部件；连接滑块，通过销连接到所述连杆的前端，被插入到形成在所述操作框架内侧的导向长槽的状态下，根据所述操作框架的旋转操作而随着所述导向长槽移动，从而引导所述操作框架的旋转。
优选地，在所述连接滑块的上端突出形成突起，在所述操作框架的内侧上端，形成根据所述操作框架的旋转操作而与所述突起碰撞的阻挡部。
(发明的效果)
本发明的效果在于，通过铰链轴来连接设置在门上的操作框架与设置在门框的固定部件时,以铰链支架为媒介而连接，从而能够向前方卧倒，完成打开操作后的门的高度低于烤箱的内部空间底面，因此从烤箱取出盛放食物的托盘的过程中，不会碰到门而安全地取出。
并且，在实现门的关闭操作时，可以降低门的关闭速度，防止门与烤箱的门框发生碰撞而破损或产生严重噪音的问题。
附图说明
图1示出本发明的优选实施例的门铰链的结构。
图2立体地示出图1的门铰链主要构件。
图3示出本发明中门正在关闭的状态。
图4示出通过本发明的门铰链进行打开操作的状态。
具体实施方式
在下文中，将参考附图描述本发明的实施例。后述的详细说明中，为了解决上述技术问题，将示出代表本发明的两个实施例。并且，本发明的其他实施例将在本发明的结构中体现。
图1示出本发明的优选实施例的门铰链的结构，图2立体地示出门铰链的主要构件。
如图1及图2所示，本发明的门铰链设置在以门200的上端为起点而向上、下推拉(即，向前拉开的方式)开闭的各种家电产品(烤箱)，包括：固定部件10，安装在门框100；操作框架20，安装在门200上，通过铰链支架40而与所述固定部件10连接；以及连杆装置30，连接所述固定部件10与所述操作框架20，引导所述操作框架20的旋转操作而使其稳定地实现操作。
所述操作框架20在被安装到所述门200的状态下，通过铰链支架40而与所述固定部件10连接，以连接所述铰链支架40与所述固定部件10的铰链轴48为中心而实现旋转操作，支撑门200而能够使其打开。
所述连杆装置30起到引导作用，从而基于门200的打开的操作框架20的旋转操作能够稳定地实现。
所述连杆装置30包括：连杆32，其末端销34连接到所述固定部件10；连接滑块36，销38连接到所述连杆32的前端，被插入到形成在所述操作框架20内侧的导向长槽22的状态下，根据所述操作框架20的旋转操作而随着所述导向长槽22移动，从而引导所述操作框架20的旋转。
在所述连接滑块36的上端突出形成突起37，形成在所述操作框架20的内侧上端的阻挡部24与所述突起37碰撞，从而降低门200的关闭速度，使得门200不会突然关闭。
即，为了关闭打开的门200而往上提所述门200，则所述操作框架20向与门200的打开方向相反的方向旋转，从而关闭门200，此时，操作框架20的旋转从门200的打开起点达到大约70°时，所述连接滑块36的突起37与形成在所述操作框架20的内侧上端的阻挡部24发生碰撞，从而降低门200的关闭速度，防止门200与烤箱400的门框100发生碰撞而破损或产生严重噪音。
所述主弹簧50的一端固定到操作框架20，另一端连接到所述连接滑块36，从而弹性支撑所述操作框架20的旋转操作。
所述铰链支架40将所述操作框架20可旋转地连接到所述固定部件10。
所述铰链支架40包括：板42，在贴紧所述操作框架20的下端内侧的状态下，通过螺栓连接；及间隙保持件46，截面形状为"匚"形，其中心形成空间44，前端与所述板42的下端结合，其末端在向所述操作框架20的下端外部露出的状态下，通过铰链轴48连接到形成在所述固定部件10下端两侧的固定销12。
所述间隙保持件46基于形成在中心的空间44所具有的距离，将铰链轴48以最大限度往下地结合到固定部件10上，从而操作框架20以所述铰链轴48为中心旋转而打开门200的过程中，使得所述门200完全向前方卧倒，完成打开操作的时点，使门200的高度低于烤箱400的烹饪空间底面410，在从烹饪空间取出盛放食物的托盘420的过程中，防止托盘420与门200发生碰撞而食物掉落等安全事故。
即，将操作框架20的下端直接通过铰链轴48连接到固定部件10时，因门200本身的厚度而即使完成所述门200的打开操作，门200的高度也将在烤箱400的烹饪容器底面410之上，这种情况下，从烤箱400取出食物托盘420的过程中，存在托盘420与门200相撞而食物掉落的危险。
但是，如本发明，通过铰链轴48连接操作框架20与固定部件10时，使铰链支架40的间隙保持件46介于两者之间，基于所述间隙保持件46的空间44所具有的距离，将铰链轴48以最大限度往下地结合到固定部件10上，从而与门200的厚度无关地，使完成打开操作的门200的高度低于烤箱400的烹饪空间底面410，防止门200与托盘420相撞。
