본 고안은 세탁기의 도어개폐장치에 관한 것으로, 특히 도어의 개폐를 정확히 감지하여 탈수도중 발생되는 안전사고를 미연에 방지하여 줄 수 있도록 한 세탁기의 도어개폐장치에 관한 것이다.The present invention relates to a door opening and closing device of the washing machine, and more particularly, to a door opening and closing device of the washing machine to accurately detect the opening and closing of the door to prevent a safety accident occurring during dehydration in advance.

일반적으로 도어의 개폐감지는 도어의 후방 일측으로 돌출된 작동편이 안전스위치의 도어감지레버를 상승시켜 주어 마이크로스위치의 접점이 접지되도록 한 상태에서 도어가 열리게 되면 작동편이 힌지를 중심으로 하여 하향으로 회동되므로서 이에 의해 상승되어 있는 안전스위치의 도어감지레버가 떨어지면서 마이크로스위치의 접점이 떨어져 도어가 열린 것을 감지하도록 되어 있는 것이다.In general, the opening and closing detection of the door is rotated downwardly around the hinge when the door is opened while the operation piece protruding to the rear side of the door raises the door detection lever of the safety switch so that the contact of the micro switch is grounded. As a result, the door detection lever of the safety switch, which is raised, is dropped, and the contact of the micro switch is dropped to detect that the door is opened.

이러한, 종래의 도어개폐 감지장치는 도어의 후방 일측에 구성되어 소정의 길이를 갖고 돌출되어 안전스위치의 감지레버의 선단하부로 절곡된 절곡면을 눌러주도록 구성되어 힌지축을 중심으로 하여 도어가 닫히게 되면 작동편이 안전스위치의 감지 레버의 하부를 눌러주어 감지레버가 상승을 하므로서, 마이크로스위치의 접점을 접지하여 주게 되므로서, 도어가 닫혀있음을 인지하게 된다.Such a conventional door opening and closing detection device is configured to press the bent surface bent to the lower end of the detection lever of the safety switch is configured to the rear side of the door and protrudes with a predetermined length when the door is closed around the hinge axis. As the operating piece presses the lower part of the sensing lever of the safety switch, the sensing lever is raised, thereby grounding the contact of the micro switch, thereby recognizing that the door is closed.

상기와 같은 상태에서 탈수도중 도어가 열리게 되면 이의 후방에 구성된 작동편이 열리는 도어의 힌지축을 중심으로 하여 하향 회동됨에 따라 이에의해 상승되어 있던 감지레버가 떨어지므로서 접점이 떨어져 도어가 열림을 인지하여 탈수행정을 일시적으로 정지시켜 주어 안전사고를 방지하도록 되어있는 것이다.When the door is opened during the dehydration in the above state, the operating lever configured at the rear thereof is rotated downwardly around the hinge axis of the door, whereby the sensing lever that has been raised is dropped, thereby recognizing that the door is opened and dewatering. Temporary stops to prevent accidents.

그러한, 종래의 도어개폐감지장치는 힌지를 중심으로 하여 개폐되는 도어에 의해 이의 후방 일측에 구성된 누름편에 의하여 안전스위치의 감지레버를 상,하로 작동시켜 주어 접점을 단락시켜 주도록 하고있어 기계적인 구성에 의해 작동되는 안전스위치의 고장이 발생되었을 경우 도어가 열리더라도 이의 열림을 인지하지 못하게 되는 결함이 있으며, 특히 탈수행정도중 도어가 열리는 경우에 감지를 하지 못해 탈수행정이 수행되면 고속회전되는 세탁조에 의해 안전사고를 당하게 되는 등의 제반결함이 있었던 것이다.Such a conventional door opening / closing detection device operates a detection lever of a safety switch up and down by a pressing piece configured at a rear side thereof by a door opened and closed around a hinge, thereby shorting a contact. If the safety switch operated by the fault occurs, even if the door is opened, the opening is not recognized.In particular, when the door is opened during the dehydration process, it is not detected. There were various defects such as being caused to safety accidents.

따라서, 본 고안의 목적은 도어의 개폐시 오동작이 없이 정확히 감지할 수 있도록 하는 안전사고를 미연에 방지할 수 있도록 하는 세탁기의 도어개폐장치를 제공함에 있다.Accordingly, an object of the present invention is to provide a door opening and closing device of a washing machine to prevent a safety accident that can be accurately detected without malfunction when opening and closing the door.

이러한, 목적을 달성하기 위한 본 고안은 탑커어버의 상면에 얹혀져 투입구를 개폐시켜 주는 도어로 구성된 세탁기에 있어서, 탑커어버의 전방 투입구측에 외부로부터의 충격을 가하게 되면 기계적인 진동이 전기적인 진동으로 변환되어 전류를 인가시켜 주어 도어의 개폐를 감지하여 줄 수 있도록 하는 감지수단을 갖추어진 것을 특징으로 하는 것이다.The present invention for achieving the object is a washing machine consisting of a door that is placed on the top surface of the top cover to open and close the inlet, the mechanical vibration is an electrical vibration when an external shock is applied to the front inlet side of the top cover It is characterized in that it is equipped with a sensing means to convert the applied current to detect the opening and closing of the door.

이하, 첨부된 도면에 의거하여 본 고안 실시예의 구성을 설명하면 다음과 같다.Hereinafter, the configuration of the embodiment of the present invention based on the accompanying drawings.

제1도는 본 고안이 적용된 상태를 보인 세탁기의 부분절개측면도이고, 제2도는 본 고안의 구성을 보인 요부확대 단면도로서, 외체(100)의 상부에 세탁물이 투입되는 투입구(210)가 구성되고 전,후방에 각종 전장품들이 내장된 탑커어버(200)와, 상기 탑커어버의 상면에 안치되어 힌지축을 중심으로 하여 투입구를 개폐시켜 주는 도어(300)로 구성된 세탁기에 있어서, 상기 탑커어버(200)의 전방 투입구(210)측에 외부로부터의 충격을 가하게되면 기계적인 진동이 전기적인 진동으로 변환되어 전류를 인가시켜 주어 도어의 개폐를 감지하여 줄 수 있도록 하는 감지수단(400)을 갖추어되는 것이다.1 is a partial cutaway side view of a washing machine showing a state of the present invention, Figure 2 is an enlarged cross-sectional view of the main portion showing the configuration of the present invention, the injection hole 210 is configured to put the laundry in the upper portion of the outer body 100 In the washing machine consisting of a top cover 200 with various electric appliances built in the rear, and a door 300 which is placed on the top surface of the top cover and opens and closes the inlet around a hinge axis, the top cover 200 of the top cover 200 When an impact from the outside is applied to the front inlet 210 side, the mechanical vibration is converted into electrical vibration, thereby applying a current to detect the opening and closing of the door.

이때, 상기의 감지수단(400)은 탑커어버(200)의 내측에서 투입구(210)측으로 소정의 길이를 갖고 돌출되는 연질의 피에조센서(410)를 구성하고, 도어의 전면에 상기 피에조센서가 요입될 수 있도록 하는 요입부(420)로 구성하여 되는 것이다.At this time, the sensing means 400 constitutes a soft piezo sensor 410 protruding with a predetermined length from the inside of the top cover 200 toward the inlet 210 side, the piezo sensor is recessed in the front of the door It is to be configured as a concave inlet portion 420 to be.

상기와 같은 구성으로 하는 본 고안의 작용 및 효과를 설명하면 다음과 같다.Referring to the operation and effects of the present invention to the above configuration as follows.

먼저, 도어(300)가 힌지축(310)을 중심으로 하여 닫히게 되면 상기 도어(300)의 전면에 구성된 요입부(420)에 탑커어버에 매몰된 상태에서 투입구(210)측으로 소정의 길이를 갖고 돌출된 피에조센서(410) 자체의 탄성력에 의해 늘리다가 요입부(420)내로 요입되어 있게 된다.First, when the door 300 is closed about the hinge shaft 310, the door 300 has a predetermined length toward the inlet 210 in the state of being buried in the top cover in the recess 420 formed in the front of the door 300. Increasing by the elastic force of the protruded piezoelectric sensor 410 itself is to be indented into the recess 420.

이때, 도어가 열려있는 상태에서 닫힐때에는 전원이 인가되지 않는 상태에서 피에조센서에 충격이 가해짐에 따라 전류가 통전되지 않게 되는 것이다.At this time, when the door is closed in the open state, the current is not energized as a shock is applied to the piezo sensor in a state where power is not applied.

상기와 같은 상태에서 세탁물이 투입되고 전원이 인가되어 세탁물을 세탁하여 주게 되면 상기 감지수단(400)에도 전원이 인가된 상태이다.When the laundry is put in the above state and the power is applied to wash the laundry, power is also applied to the sensing means 400.

상기와 같은 상태로 하여 세탁행정을 수행하는도중 닫혀있다가 사용자의 부주의나 어린이들의 장난으로 인해 도어(300)가 열리게 되면 상기 도어의 열림에 의해 전면에 구성된 요입부(420)내에 요입되어 있는 피에조센서(410)가 도어의 열림에 의해 자체의 탄성력에 의해 휘어지면서 충격이 가해지게 되어 상기 충격에 의한 진동기 전기적 진동으로 변환되면서 전류가 통전되어 세탁행정도중 도어의 열림으로 인지하여 전원을 일시적으로 차단시켜 세탁행정을 정지시켜 주게 되는 것이다.When the door 300 is opened due to carelessness or mischief of the user while being closed while performing the washing operation in the above state, the piezo is inserted into the indentation part 420 formed at the front by the opening of the door. When the sensor 410 is bent by its elastic force by the opening of the door, an impact is applied, and the electric current is energized as the vibrator is converted into electrical vibration due to the impact, and the power is temporarily recognized as the door is opened during washing. It will stop the washing administration.

이는 탈수행정도중 도어의 열림을 정확히 감지하여 주어 전원을 차단시켜 주므로서, 고속회전되는 세탁조가 일시적으로 정지하므로서, 세탁조에 의해 손이나 기타 신체부위를 다치지 않도록 하여 안전사고를 미연에 방지할 수 있게 되는 것이다.This prevents power accidents by accurately detecting the opening of the door during dehydration, and temporarily stops the washing tank that rotates at a high speed, thus avoiding injury to hands or other body parts by the washing tank. Will be.

따라서, 본 고안은 탈수행정도중 외부로부터의 충격이나 자체의 진동에 의해 일시적이나마 도어가 미세한 범위내에서 열릴 경우 이를 정확히 감지하여 전원을 차단시켜 주므로서, 탈수 행정시 고속회전되는 세탁조에 의해 발생되는 안전사고를 미연에 방지하여 줄 수 있게 되는 효과가 있는 것이다.Therefore, the present invention, when the door is opened in a minute range by the impact from the outside or its own vibration during the dehydration degree, and accurately detects it to cut off the power, generated by the washing tank rotates at high speed during the dehydration stroke It is effective to prevent safety accidents in advance.
