Description
본 고안은 세탁기의 도어개폐 감지장치에 관한 것으로서, 보다 상세하게는 세탁기의 탈수조가 고속으로 회전하는 탈수행정시 도어의 개폐상태를 정확히 감지하여 도어가 열리면 탈수행정을 정지시켜 안전사고를 사전에 방지할 수 있도록 한 도어개폐 감지장치에 관한 것이다.The present invention relates to a door opening and closing detection device of the washing machine, and more particularly, to accurately detect the opening and closing state of the door when the dehydration tank of the washing machine rotates at high speed to stop the dehydration stroke when the door is opened to prevent safety accidents in advance. It relates to a door open and close detection device to enable.
일반적으로 도어개폐 감지장치는 탈수행정중 도어가 열리면, 열림상태를 감지하고 전원을 자동으로 차단시켜 고속으로 회전되는 세탁조에 의한 안전사고를 사전에 방지할 수 있도록 하는 곳을 일컫는다.In general, the door opening and closing detection device refers to a place that detects an open state and automatically cuts off the power when the door is opened during the dehydration operation so as to prevent a safety accident caused by the washing tank rotating at high speed in advance.
이러한 종래의 도어개폐 감지장치는 안전스위치가 탑커어버의 후방측 내면 일측에 고정 설치되어 있고, 도어의 후방측에 구성된 누름레버가 안전스위치의 전방측으로 돌설된 작동레버를 하부에서 상부로 눌러주게 되도록 구성되어 있다.The conventional door open / close detection device has a safety switch fixedly installed on one side of the inner surface of the rear side of the top cover, and a push lever configured at the rear side of the door presses the operation lever protruding toward the front side of the safety switch from the bottom to the top. Consists of.
또한, 종래의 도어개폐 감지장치는 탑커어버에 힌지축으로 결합된 도어가 힌지축을 중심으로 닫히면, 도어의 후방측에 돌설되어 있는 누름레버가 안전스의치의 작동레버의 하면에 접지된 상태에서 이를 상부로 상승시키므로 스위치의 접점이 접지되어 도어의 닫힘을 감지하고, 이와 반대로 도어가 힌지축을 중심으로 열리면 도어의 후방측에 돌설되어 있는 누름레버가 하부로 회동함에 따라 이에의해 상승되어있던 작동레버가 하부로 떨어지므로 스위치의 점검이 떨어져 도어의 열림을 감지하게 된다.In addition, in the conventional door opening and closing detection device, when the door coupled to the hinge shaft by the top cover is closed around the hinge shaft, the push lever protruding from the rear side of the door is grounded on the lower surface of the operating lever of the safety switch. Since the contact point of the switch is grounded to detect the closing of the door, and on the contrary, when the door is opened around the hinge axis, as the push lever protruding from the rear side of the door rotates to the lower side, the operating lever raised by As it falls to the bottom, the inspection of the switch is dropped and the door is opened.
그러나 상기와 같은 종래의 도어개폐 감지장치는 도어의 후방측에 탑커어버와 힌지축으로 결합된 상태로, 상기의 힌지축을 중심으로 도어가 개폐되는 바, 이때 상기 안전스위치의 작동레버를 눌러주는 누름레버가 도어의 후방측에 설치되어 있으므로, 도어의 전방측 개폐거리에 비해 후방측의 개폐거리가 상대적으로 적기 때문에 도어의 열림상태를 정확히 감지하지 못하는 단점이 있었다.However, the conventional door opening and closing detection device as described above is coupled to the top cover and the hinge shaft on the rear side of the door, the door is opened and closed around the hinge shaft, and at this time, pressing the operating lever of the safety switch Since the lever is installed at the rear side of the door, the opening and closing distance of the rear side is relatively small compared to the front opening and closing distance of the door, so that the opening state of the door cannot be accurately detected.
즉 도어는 후방측에 위치하는 힌지축을 중심으로 개폐가 이루어 지는 바, 탈수행정중 도어의 전방측이 힌지축을 중심으로 열리면 힌지축을 중심으로 후방측이 하부로 회동을 하게 되며, 이때 상기 도어의 전방측이 열리는 간격에 비해 후방측의 회동거리가 상대적으로 적기 때문에 도어의 전방측이 일정한 간격으로 열리기까지는 누름레버에 의해 상승되어 있는 작동레버가 하부로 떨어지지 않아 도어의 열림상태를 감지하지 못하고 탈수행정이 수행되어, 이런 상태에서 사용자의 신체일부 또는 기타 물품이 투입구내로 들어가면 고속 회전되는 세탁통의 회전력에 의해 안전사고가 발생하는 등의 제반 문제점이 있었다.In other words, the door is opened and closed about the hinge shaft located at the rear side, and when the front side of the door is opened around the hinge shaft during the dehydration operation, the rear side rotates to the lower side about the hinge shaft, and the front of the door Since the rotational distance of the rear side is relatively small compared to the opening interval of the side, the operating lever that is raised by the push lever does not fall to the lower side until the front side of the door is opened at regular intervals, so that the opening state of the door cannot be detected and the dehydration stroke In this state, when a part of the user's body or other items enters the inlet in this state, there is a general problem such as a safety accident occurs due to the rotational force of the laundry container being rotated at high speed.
본 고안은 상기한 바와 같은 종래의 제반 문제점을 해결하기 위하여 안출된 것으로서, 본 고안의 목적은 안전스위치를 탑커어버의 전방일측에 설치하여 세탁도중 도어의 열림상태를 정확히 감지하고, 도어가 열리면 전원을 차단시켜 안전사고를 사전에 방지할 수 있는 세탁기의 도어개폐 감지장치를 제공하는 데 있다.The present invention is conceived to solve the conventional problems as described above, the object of the present invention is to install a safety switch on the front side of the top cover to accurately detect the open state of the door during washing, when the door is open It is to provide a door opening and closing detection device of the washing machine that can prevent the safety accident by blocking the.
