Description

세탁기의 제어방법Washing machine control method

본 발명은 세탁기의 제어방법에 관한 것으로, 특히 세탁기주위로의 인체의 접근을 감지하면 행정을 일시 중지하도록 세탁기의 제어방법에 관한 것이다.The present invention relates to a control method of a washing machine, and more particularly, to a control method of a washing machine to pause the stroke when sensing the human body approaching the washing machine.

일반적인 세탁기는, 도 1에 도시된 바와 같이, 본체(1)와, 상기 본체내부의 세탁조(2)와 상기 세탁조의 내부에 회전가능하게 설치된 탈수조(3)와, 탈수조내의 하부 중앙에 설치되어 세탁 및 탈수시 좌.우 교반하는 세탁날개(4)와, 세탁조의 하부에 설치되어 세탁기전체시스템을 제어하는 제어부(미도시)의 제어신호에 의해 동력을 발생하는 모터(8)와, 상기 모터(8)에서 발생된 동력을 전달하기 위한 벨트(9)와, 상기 모터의 동력을 벨트를 통해 전달받아 상기 탈수조와 세탁날개를 회전시키는 클러치(5)와, 제어부의 제어신호에 의해 세탁조 내부로 세탁수를 공급하는 급수밸브(12)와, 세탁조내의 세탁수를 배출하는 배수 밸브(14)로 구성되어 있다.As shown in FIG. 1, a general washing machine includes a main body 1, a washing tank 2 inside the main body, a dehydration tank 3 rotatably installed inside the washing tank, and a lower center in the dewatering tank. And washing blades 4 for stirring left and right during washing and dehydration, a motor 8 installed at the lower part of the washing tank and generating power by a control signal of a controller (not shown) for controlling the whole washing machine system; Belt 9 for transmitting power generated from the motor 8, clutch 5 for receiving the power of the motor through the belt to rotate the dehydration tank and the washing blade, and the inside of the washing tank by the control signal of the control unit And a drain valve 14 for discharging the washing water in the washing tank.

이와 같이 구성된 세탁기의 세탁과정을 설명한다.The washing process of the washing machine configured as described above will be described.

먼저, 사용자가 세탁물을 투입한 상태에서 전원을 공급하고 시작키를 누르게 되면 제어부는 세탁모터를 좌,우로 반전 구동시켜 포량을 감지한 후 그 감지된 포량에 대응되는 수위를 설정하고, 급수밸브를 턴온시켜 급수를 행한다. 급수가 완료가 되면, 세탁모터(8)을 구동시켜 세탁날개(4)를 좌,우로 일정주기를 갖고 회전시키어 세탁행정을 진행한다. 세탁행정이 완료되면, 배수밸브(14)를 턴온시키어 배수를 행하고, 배수가 완료되면 탈수행정을 위해 상기 세탁모터(8)를 재기동시키어 탈수조를 회전시키어 세탁물내의 잔수를 배수밸브를 통해 배수하여 탈수한다. 이후 상기 세탁수위와 동일한 재급수를 행하고, 세탁모터를 재기동시키어 세탁날개를 좌,우로 반전시키어 헹굼행정을 진행하고, 헹굼행정이 완료되면 상기와 같이 배수를 행하고, 탈수행정을 반복한 후 세탁과정을 종료하게 된다.First, if the user supplies power while the laundry is put in and presses the start key, the controller reversely drives the washing motor to the left and right to detect the quantity and sets the water level corresponding to the detected quantity. Turn on to supply water. When the water supply is completed, the washing motor 8 is driven to rotate the washing blades 4 at regular intervals to the left and right to perform the washing operation. When the washing stroke is completed, the drain valve 14 is turned on to drain the water, and when the draining is completed, the washing motor 8 is restarted to rotate the dewatering tank for the dehydrating stroke to drain the remaining water in the laundry through the drain valve. Dehydrate After the same water level as the wash water, restart the washing motor to reverse the washing blades left and right to proceed with the rinsing stroke, draining as described above when the rinsing stroke is completed, the washing process after repeating the dehydration stroke Will end.

한편, 탈수 중에 세탁기 뚜껑(19)를 열면 탈수 행정이 일시 중지되고, 상기 뚜껑(19)을 닫으면 탈수 행정이 계속 진행되도록 되어 있다.On the other hand, when the washing machine lid 19 is opened during dehydration, the dehydration stroke is suspended, and when the lid 19 is closed, the dehydration stroke is continued.

그러나, 탈수중 뚜껑이 열려 행정이 중시되더라도 회전하던 탈수조는 회전관성력에 의해 바로 정지되지 않으므로, 뚜껑을 여는 경우는 사용자가, 특히 어린이가 부상당할 염려가 있었다.However, even when the lid is opened during the dehydration and the administration is important, the rotating dehydration tank does not stop immediately due to the rotational inertia, so when the lid is opened, the user, especially a child, may be injured.

본 발명은 이러한 종래기술의 문제점을 해결하기 위한 것으로, 세탁기 본체 주위로 인체가 감지되면 세탁기의 행정을 일시 정지할 수 있는 세탁기의 제어방법의 제공을 목적으로 한다.The present invention is to solve the problems of the prior art, it is an object of the present invention to provide a control method of the washing machine that can pause the stroke of the washing machine when the human body is sensed around the washing machine body.

상기 목적을 달성하기 위하여, 본 발명의 세탁기의 제어방법은, 행정 진행중에 세탁기 주위로 인체의 접근을 감지하면, 행정을 일시 중단하는 것을 특징으로 한다.In order to achieve the above object, the control method of the washing machine of the present invention is characterized in that the stroke is suspended when the human body approaches the washing machine while the stroke is in progress.

이하, 첨부도면에 의거하여 본 발명을 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

본 발명의 세탁기에는, 도 3에 도시된 바와 같이, 인체로부터 나오는 적외선을 감지하여 감지신호를 제어부에 입력하는 인체감지부(15)가 본체(1)의 상부의 소정위치에, 특히, 어린이의 키의 위치에, 설치되어 있다.In the washing machine of the present invention, as shown in Figure 3, the human body sensing unit 15 for sensing the infrared rays from the human body and inputting the detection signal to the control unit, in a predetermined position of the upper portion of the main body 1, in particular, of children It is installed at the key position.

상기 인체감지부(15)는, 도 4 및 도 5에 도시된 바와 같이, 인체로부터 나오는 적외선을 감지하는 초전형 적외선 센서모듈(17)과, 상기 모듈의 감지신호를 좌/우로 분할입력받아 인체가 위치한 영역을 감지하는 프라즈넬 렌즈(18)로 구성되고, 상기 프라즈넬렌즈(18)는 볼록렌즈로 하고, 상기 렌즈를 통해 좌측으로부터 들어온 적외선은 우측의 제2초전형센서(16b)로 입사될 수 없고, 우측으로부터 들어온 적외선의 좌측의 제1초전형센서(16a)로 입사될 수 없도록, 상기 렌즈의 볼록면을 칸막이(20)로 분할하여 각 분할면마다의 굴절각도를 달리하여 초전형 적외선모듈(17)에 촛점을 맞추도록 구성한다.As shown in FIGS. 4 and 5, the human body detecting unit 15 receives a pyroelectric infrared sensor module 17 that detects infrared rays emitted from the human body, and receives a detection signal of the module in left / right directions. It consists of a Prasnel lens 18 for detecting the area where the position is located, the Prasnel lens 18 is a convex lens, the infrared ray from the left through the lens is incident to the second pyroelectric sensor 16b on the right. The convex surface of the lens is divided into partitions 20 so as not to be incident to the first pyroelectric sensor 16a on the left side of the infrared ray coming from the right side, and thus the refractive angle of each divided surface is varied so as to be pyroelectric. It is configured to focus on the infrared module (17).

이하, 본 발명의 세탁기의 제어방법의 작용을 설명한다.Hereinafter, the operation of the control method of the washing machine of the present invention will be described.

먼저, 세탁 또는 헹굼 행정시 시작되면 제어부 명령에 의해 급수밸브를 동작시키어 급수를 행하고, 급수행정이 완료된 후 모터가 기동되어 세탁행정, 헹굼행정, 탈수행정을 진행한다. 한편, 상기 행정진행중에, 세탁기 본체(1) 앞에 인체가 나타나면, 상기 인체감지부(15)는, 인체로부터의 적외선을 감지하여 감지 신호를 제어부를 보내고, 상기 신호를 받은 제어부는, 행정을 일시 중지시키고, 인체의 접근이 사라질 때까지 경보를 알린다. 상기 인체가 없어지면, 상기 인체감지부(15)는, 인체로부터의 적외선의 사라짐을 감지하여 감지 신호를 제어부를 보내고, 상기 신호를 받은 제어부는, 행정을 다시 진행시킨다.First, when the washing or rinsing stroke starts, the water supply valve is operated by the control unit command to supply water, and after the water supply stroke is completed, the motor is started to perform the washing stroke, the rinsing stroke, and the dehydration stroke. On the other hand, when the human body appears in front of the washing machine main body 1 during the administration, the human body detecting unit 15 detects infrared rays from the human body and sends a detection signal to the control unit, the control unit receiving the signal is temporarily suspended Stop and alert until the human body disappears. When the human body disappears, the human body detecting unit 15 detects the disappearance of the infrared rays from the human body and sends a control signal to the control unit, and the control unit which receives the signal advances the stroke again.

이상, 설명한 바와 같이, 본 발명에 따르면, 행정진행중에, 세탁기에 인체가 접근하면, 행정을 일시 중지시키어, 세탁기에 의한 인체의 상해를 방지할 수 있다.As described above, according to the present invention, when the human body approaches the washing machine during the administration, the administration can be paused to prevent injury to the human body by the washing machine.
