본 발명은 세탁기덮개의 개폐 감지장치에 관한 것으로, 특히 덮개의 개폐 감지에 따른 오동작을 방지하고, 사용수명을 반영구적으로 할 수 있게 한 세탁기덮개의 개폐 감지장치에 관한 것이다.The present invention relates to an opening and closing detection device for a washing machine cover, and more particularly, to an opening and closing detection device for a washing machine cover, which prevents a malfunction due to the opening and closing detection of a cover and makes the service life semipermanent.
일반적인 세탁기는, 제 1 도에 도시한 바와같이, 본체(1)의 상면에 복개고정되는 상면판(top cover)(2)의 내부에 안전스위치(3)가 설치되어 덮개(2)의 개폐 동작을 감지하도록 구성되어 있다.In the general washing machine, as shown in FIG. 1, the safety switch 3 is installed inside the top cover 2 which is fixed to the upper surface of the main body 1 to open and close the operation of the cover 2. It is configured to detect.
상기 안전스위치(3)는 제 2 도 및 제 3 도에 도시한 바와같이, 덮개(2)에 의하여 눌려지는 덮개 개폐 감지레버(4)와, 탈수시 세탁조(7)의 불균형(unbalance) 회전을 감지하는 불균형 회전감지레버(5)로 구성되어, 세탁기의 덮개(2)가 개방될 경우, 그 덮개(2)가 덮개 개폐 감지레버(4)를 도시한 화살표 A 방향으로 눌러 안전스위치(3)의 내부 접점을 오프(off)시키거나, 또는 탈수시 세탁조(7)가 회전되면서 불균형으로 인하여 불균형 회전감지레버(5)를 도시한 화살표 B 방향으로 밀 경우, 상기 불균형 회전감지레버(5)가 밀려지는 동안 안전스위치(3)의 내부 접점을 오프시키도록 되어 있다.As shown in FIGS. 2 and 3, the safety switch 3 is configured to prevent the unbalanced rotation of the cover opening / closing detection lever 4 pressed by the cover 2 and the washing tub 7 when dewatering. When the cover 2 of the washing machine is opened, the cover 2 is pushed in the direction of the arrow A showing the cover opening and closing detection lever 4 when the cover 2 of the washing machine is opened. When the internal contact of the off (off), or when the washing tank 7 is rotated during dehydration, when the imbalance rotation detection lever 5 is pushed in the direction of the arrow B shown by the imbalance, the imbalance rotation detection lever 5 is The internal contact of the safety switch 3 is turned off while being pushed.
상기 안전스위치(3)의 회로적인 접속관계는 제 4 도에 도시한 바와 같다.The circuit connection relationship of the safety switch 3 is as shown in FIG.
예를들어, 안전스위치(3)의 접점이 오프가 되면, 마이콤(6)의 P1 포트(port)에서는 고전위(high)가 인식되며, 반대로 접점이 온(on)되면, 마이콤(6)의 P1 포트에서는 저전위(low)가 인식하도록 한다.For example, when the contact point of the safety switch 3 is turned off, the high potential is recognized at the P1 port of the microcomputer 6, and conversely, when the contact point is turned on, the Low potential is recognized on the P1 port.
상기 안전스위치(3)의 작용을 보다 상세하게 설명하면, 덮개(2)를 열었을 경우에는 안전스위치(3)의 접점이 200ms 이상되었을 경우, 마이콤(6)에서 덮개(2)가 열린 것으로 인식하게 되며, 또한 탈수시 세탁조(7)가 불균형 회전하여 불균형 회전감지레버(5)를 칠 경우, 이때 안전스위치(3)의 접점이 66ms-200ms 동안 오프되면, 마이콤(6)에서 세탁조(7)의 불균형 회전을 감지하게 되는 것이다.The operation of the safety switch 3 will be described in more detail. When the cover 2 is opened, if the contact of the safety switch 3 is 200 ms or more, the microcomputer 6 recognizes that the cover 2 is open. In addition, when the washing tank (7) unbalanced rotation and hit the imbalance rotation detection lever (5) during dehydration, if the contact of the safety switch (3) is off for 66ms-200ms, the microcomputer (6) of the washing tank (7) It will detect an unbalanced rotation.
한편, 안전스위치(3)의 접점이 66ms 이하일 경우에는 노이즈(noise)로 인식하고 마이콤(6)에서 이를 무시하게 된다.On the other hand, when the contact of the safety switch 3 is 66ms or less, it is recognized as noise and ignored by the microcomputer 6.
그러나, 상기한 바와같은 종래 기술에 의하면, 안전스위치(3)의 기능이 덮개(2)의 개폐 감지동작과, 세탁조(7)의 불균형 회전감지동작을 겸용하도록 되어 있으므로 오동작이 발생되는 문제점이 있는 것이었다.However, according to the prior art as described above, since the function of the safety switch 3 is to use the opening and closing detection operation of the lid 2 and the unbalanced rotation detection operation of the washing tank 7 there is a problem that a malfunction occurs Was.
즉, 덮개(2)를 살짝 들었다 놓게 되면, 이때의 안전스위치(3)의 접점이 66ms-200ms 동안 오프되었다가 온이 됨으로써 마이콤(6)에서는 세탁조(7)의 불균형 회전이라고 인식하게 되는 단점이 있었다.That is, when the cover 2 is slightly lifted and released, the contact point of the safety switch 3 at this time is turned off for 66ms-200ms and then turned on so that the microcomputer 6 recognizes that the washing tank 7 is unbalanced rotation. there was.
이와같이 마이콤(6)이 세탁조(7)의 불균형 회전을 감지하게 되면, 통상의 방법대로 세탁조(7)의 세탁물을 고르게 하기 위하여 헹굼공정을 일정시간 동안 실시한 후, 즉 세탁수를 일정시간 동안 공급한 후에 탈수공정을 수행하는 오동작이 발생하게 되는 것이다.When the microcomputer 6 detects an unbalanced rotation of the washing tank 7, the rinsing process is performed for a predetermined time to uniformly wash the laundry of the washing tank 7, that is, the washing water is supplied for a predetermined time. After that, a malfunction occurs to perform the dehydration process.
또한, 통상적으로 덮개(2)를 8cm 정도 열었을 경우, 안전스위치(3)의 접점이 오프되도록 되어 있는 바, 사용자가 덮개(2)를 8cm 정도 열고서 가만히 손으로 잡고 있으며, 안전스위치(3)의 접점이 온/오프를 계속 반복하는 채터링(chattering)을 일으켜 마이콤(6)에서 세탁조(7)의 불균형 회전으로 인식하여 헹굼공정을 진행하기 위하여 급수를 하는 오동작이 발생되기도 한다.In addition, when the cover 2 is opened by about 8 cm, the contacts of the safety switch 3 are normally turned off, and the user opens the cover 2 by about 8 cm and gently holds the cover by the hand. The contact point of the continually repeats the chattering (chattering) to recognize the imbalanced rotation of the washing tank 7 in the microcomputer 6 may cause a malfunction of water supply to proceed with the rinsing process.
뿐만 아니라, 탈수공정을 수행하기 위하여 세탁조(7)가 회전될 경우, 초기에는 속도(PRM)가 매우 느린 상태에서 불균형 회전에 의하여 안전스위치(3)의 불균형 회전감지레버(5)를 치게 되면, 안전스위치(3)의 접점시간이 200ms 이상이 되는데, 이와같은 경우에는 세탁조(7)의 불균형 회전으로 인식하지 못하고 「도어 에러(DOOR ERROR)」, 즉 덮개(2)가 개방된 것으로 인식하게 되는 단점이 있었다.In addition, when the washing tank (7) is rotated to perform the dehydration process, initially hit the imbalance rotation detection lever (5) of the safety switch (3) by the imbalance rotation in a very slow state (PRM), The contact time of the safety switch 3 is 200 ms or more. In this case, the door is not recognized as an unbalanced rotation of the washing tub 7 and the door 2 is recognized as being open. There was a downside.
또한, 상기 안전스위치(3)는 기계식 접점식을 적용함으로써 수명이 단축되는 등의 여러 문제점이 있었다.In addition, the safety switch 3 has a number of problems such as shortening the life by applying a mechanical contact type.

상기 발광부(14)는 일예로, 적외선 발광다이오드(LED)를 사용하고, 수광부(15)는 수광 트랜지스터(TR)를 사용할 수 있으나, 꼭 이에 한정하는 것은 아니다.For example, the light emitting unit 14 may use an infrared light emitting diode (LED), and the light receiving unit 15 may use a light receiving transistor TR, but is not limited thereto.
상기 광센서(16)는 본체(11)의 상면판(12)에 설치하고, 상기 광반사판(17)은 광센서(16)에 대응되는 덮개(13)의 하면 일정부위에 형성하는 것이 바람직하다.The optical sensor 16 is installed on the upper surface plate 12 of the main body 11, the light reflection plate 17 is preferably formed at a predetermined portion of the lower surface of the cover 13 corresponding to the optical sensor 16. .
그러나, 꼭 이에 한정하는 것은 아니며, 본체(11)의 상면판(12)에 광반사판(17)을 형성하고, 덮개(13)에 광센서(16)를 설치하여도 무방하다.However, the present invention is not limited thereto, and the light reflection plate 17 may be formed on the upper surface plate 12 of the main body 11, and the optical sensor 16 may be provided on the cover 13.
제 7 도는 본 발명에 의한 세탁기덮개의 개폐 감지장치를 구성하는 광센서(16)의 회로 결선도로서, 수광부(15)의 한 단자와 마이콤(18)의 사이에 회로를 연결하여 수광부(15)가 온/오프되는 것을 마이콤(18)이 감지하도록 되어 있다.7 is a circuit connection diagram of the optical sensor 16 constituting the opening and closing detection device of the washing machine cover according to the present invention, wherein the light receiving unit 15 is connected by connecting a circuit between one terminal of the light receiving unit 15 and the microcomputer 18. The microcomputer 18 is configured to detect the on / off.
한편, 본 발명의 세탁기덮개 개폐 감지장치가 구비된 세탁기의 안전스위치(제 1 도 내지 제 4 도에 도시)(3)는 세탁조(7)이 불균형 회전만을 감지하는 독립된 기능을 수행하도록 구성되며, 접점이 66ms 이상 오프되면, 전용마이콤에서 세탁조(7)의 불균형 회전을 감지하게 된다.On the other hand, the safety switch (shown in FIGS. 1 to 4) 3 of the washing machine equipped with a washing machine cover opening and closing detection device of the present invention is configured to perform an independent function of the washing tank 7 detects only an unbalanced rotation. When the contact is off for more than 66ms, the dedicated microcomputer detects an unbalanced rotation of the washing tub 7.
이와같이 구성되는 본 발명에 의한 세탁기덮개의 개폐 감지장치의 작용효과를 설명하면 다음과 같다.Referring to the effect of the opening and closing detection device of the washing machine cover according to the present invention configured as described above are as follows.
제 6 도에 도시한 바와 같이, 본체(11)에 덮개(13)가 닫혀져 있는 상태에서는 발광부(14)에서 방사되는 적외선이 덮개(13)의 내측면에 형성된 광반사판(17)에 반사되어 수광부(15)로 입사하게 된다.As shown in FIG. 6, in the state in which the cover 13 is closed on the main body 11, infrared rays emitted from the light emitting part 14 are reflected by the light reflecting plate 17 formed on the inner surface of the cover 13. It enters into the light receiving unit 15.
이와같이 수량부(15)에 발광부(14)의 적외선이 입사되면, 온(on)이 되어 마이콤(18)의 P1 포트에서 저전위(low) 신호가 인가되며, 따라서 덮개(13)가 닫혀져 있는 것으로 마이콤(18)이 인식하게 되는 것이다.When the infrared ray of the light emitting unit 14 enters the water quantity unit 15 in this manner, the signal is turned on and a low potential signal is applied from the P1 port of the microcomputer 18, so that the lid 13 is closed. The microcomputer 18 recognizes this.
한편, 제 5 도에 도시한 바와같이, 본체(11)로부터 덮개(13)를 열었을 경우에는 광반사판(17)이 본체(11)로 부터 멀어지게 되므로 발광부(14)의 적외선이 수광부(15)로 입사되지 않게 되는 것이며, 따라서 수광부(15)는 오프(off)가 되어 마이콤(18)의 P1 포트에는 고전위(high) 신호가 인가됨으로써 덮개(13)가 열려져 있는 것으로 마이콤(18)이 인식하게 되는 것이다.On the other hand, as shown in FIG. 5, when the cover 13 is opened from the main body 11, the light reflecting plate 17 moves away from the main body 11, so that the infrared rays of the light emitting portion 14 receive the light receiving portion 15. Therefore, the light receiving unit 15 is turned off, and the cover 13 is opened by applying a high potential signal to the P1 port of the microcomputer 18 so that the microcomputer 18 is opened. It will be recognized.
상기한 덮개(13)의 개폐상태 감지동작과 무관하게 기존의 안전스위치(3)는 세탁기의 불균형 회전 동작만을 감지하게 된다.Regardless of the opening / closing state detection operation of the cover 13, the existing safety switch 3 detects only an unbalanced rotation operation of the washing machine.
즉, 세탁시 세탁조(7)가 불균형 회전을 하여 불균형 회전감지레버(5)를 치게 될 경우, 안전스위치(3)의 접점이 66ms 이상 동안 오프되면, 전용마이콤에서 세탁조(7)의 불균형 회전을 감지하게 되는 것이다.That is, when the washing tank 7 is unbalanced during the washing and hits the imbalance rotation detection lever 5, when the contact of the safety switch 3 is turned off for more than 66 ms, the unbalanced rotation of the washing tank 7 is performed in the dedicated microcomputer. Will be detected.
이상에서 설명한 바와같이, 본 발명에 의한 세탁기덮개의 개폐 감지장치는, 덮개의 개폐 동작을 무접점식 스위치의 일종인 광센서와 광반사판을 사용하여 감지하도록 함으로써 덮개의 개폐 감지에 따른 오동작을 방지하고, 사용수명을 반영구적으로 늘이는 등의 효과가 있다.As described above, the opening and closing detection device of the washing machine cover according to the present invention, by detecting the opening and closing operation of the cover by using an optical sensor and a light reflector that is a kind of a contactless switch to prevent the malfunction due to the opening and closing detection of the cover. It is effective in semi-permanently extending the service life.
즉, 덮개의 개폐 감지동작을 광센서를 이용함으로써 탈수증 덮개를 열었다 닫았다 하거나, 또는 기존 안전스위치의 채터링 현상에 의한 세탁조 불균형 회전으로 오인식하는 현상을 완전하게 배제할 수 있는 것이다.In other words, the opening and closing of the dehydration cover by using an optical sensor for the opening and closing detection of the cover, or the misrecognition of the washing tank imbalance rotation due to the chattering phenomenon of the existing safety switch can be completely excluded.
또한, 기존의 안전스위치를 세탁조의 불균형 회전을 감지하기 위한 전용스위치로 사용함으로써 그 안정스위치의 접점시간을 66ms 이상으로 설정할 수 있으므로 탈수 초기에 속도가 느릴 경우에도 세탁조의 불균형을 정확하게 인실할 수 있으며, 탈수 초기에 헹굼공정을 통하여 세탁물을 고르게 하는 등의 효과가 있다.In addition, by using the existing safety switch as a dedicated switch to detect the unbalanced rotation of the washing tank, the contact time of the stability switch can be set to 66 ms or more, so that the imbalance of the washing tank can be accurately corrected even when the speed is slow at the beginning of dehydration. In the initial stage of dehydration, there is an effect of evening the laundry through a rinsing process.
