Abstract

본 발명은 세탁기 도어의 자동 개폐장치 및 방법에 관한 것으로, 종래에는 세탁시 세탁기 도어률 손으로 직접 열거나 닫아야 하는 불편함이 있고, 도어가 접혀지는 방식을 사용함으로써 도어가 열린 상태에서 주위의 충격에 의해 도어가 저절로 닫혀져 도어파손의 우려가 있으며, 장시간 사용할 경우엔 이음매가 낡아서 도어가 열린 상태에서 저절로 닫혀버리는 등의 문제점이 있었다.The present invention relates to an automatic opening and closing device and method of the washing machine door, conventionally has the inconvenience of directly opening or closing the washing machine door rate when washing, by using a method that the door is folded, the impact of the surroundings in the open state of the door The door is closed by itself and there is a risk of door breakage, and when used for a long time, there is a problem such that the seam is old and closed by itself in the open state.

따라서 종래의 문제점을 해결하기 위하여 본 발명은 세탁기 도어를 구동하는 도어구동용 모터를 도어하부 및 세탁기 몸체에 설치하여 세탁하기전이나 세탁완료시에 자동으로 도어를 열고 세탁시에 자동으로 도어를 닫도록 하거나, 세탁기 전면에 적외선 감지센서를 설치하여 사용자가 세탁하고자 세탁기 앞에서면 그 사용자로부터 적외선을 감지하거나 세탁완료시엔 자동으로 도어를 열어 주고 세탁시엔 자동으로 도어를 닫아주도록 함으로써 사용자에게 괸리함을 제공한 효과가 있다.Therefore, in order to solve the conventional problems, the present invention is to install the door driving motor for driving the washing machine door in the lower door and the washing machine body to automatically open the door before washing or at the completion of washing to automatically close the door at the time of washing. Alternatively, by installing an infrared sensor on the front of the washing machine, the user can detect infrared rays from the user in front of the washing machine or automatically open the door when the washing is completed, and automatically close the door when washing to provide the user with convenience. It works.
