본 고안은 전자동 세탁기의 세탁상태 검출장치에 관한 것으로서, 더욱 상세하게는 세탁이 행해질때 센서가 세탁조 내의 각종 상태를 직접 감지하여 검출할 수 있도록 한 것이다.The present invention relates to an apparatus for detecting a washing state of a fully automatic washing machine, and more particularly, to allow a sensor to directly detect and detect various states in a washing tank when washing is performed.

종래의 전자동 세탁기는 제1도에 나타낸 바와같이, 세탁물과 세탁수 및 세제가 투입되어 직접세탁이 행해지는 통인 세탁조(2)와, 그 외부에서 세탁수가 새지 않도록 보호하게 되는 외조(10), 그리고 맥동적으로 회전하여 세탁수의 와류를 형성시키고 세탁물과 부딪치기도 하여 세탁을 행하는 펄세이터(Pulsator)와, 상기 펄세이터(8) 및 펄세이터(8)가 설치되는 구동축(11)을 회전시키기 위한 모터(6)가 케이스 하부에 장착된다.In the conventional fully automatic washing machine, as shown in FIG. 1, laundry, washing tub 2 into which laundry and washing water and detergent are put into direct washing, and outer tub 10 which protects the washing water from leaking from the outside thereof, and Pulsator (Pulsator) to rotate by pulsating to form the vortex of the wash water and also to wash the laundry, and to rotate the drive shaft 11 is installed the pulsator (8) and the pulsator (8) The motor 6 is mounted at the bottom of the case.

한편, 세탁기능이 수행될 경우 세탁기의 세탁조(2)내부의 세탁물 및 세탁수 등의 각종 상태를 검출하여 콘트롤러(7a)가 검출된 정보를 처리하도록 해주는 센서박스(1)가 외조(10)에 장착되어 구성된다.On the other hand, when the washing function is performed, the sensor box 1 which detects various conditions such as laundry and washing water in the washing tank 2 of the washing machine and processes the detected information on the outer tank 10 is detected. It is configured to be mounted.

따라서, 사용자가 세탁물을 세탁조(2)에 넣고 콘트롤러(7a)의 스타트버튼을 누르면, 모터(6)는 서서히 회전하고 이때 센서박스(1)의 각종센서가 작동되어 세탁상태를 검출하고 이 검출량을 다시 콘트롤러(7a)에 피드백(Feedback)시키면 콘트롤러(7a)는 세탁물의 양과 오염도 등을 감안하여 세탁할 물의 높이 및 세탁코스 등을 결정하고 상기 모터(6)에 신호를 인가하여 세탁상태 및 기능모드에 알맞은 RPM으로 모터(6)를 구동시키게 되므로 세탁이 진행된다.Therefore, when the user puts the laundry into the washing tank 2 and presses the start button of the controller 7a, the motor 6 rotates slowly, and various sensors of the sensor box 1 operate to detect the washing state and detect the detected amount. When the feedback is fed back to the controller 7a, the controller 7a determines the height of the water to be washed, the washing course, etc. in consideration of the amount of the laundry and the degree of contamination, and applies a signal to the motor 6 to wash the state and the function mode. Since the motor 6 is driven at an appropriate RPM, the washing proceeds.

이때, 세탁조(2)내의 각종 상태는 센서박스(1)의 센서에 의해 수시로 감지되어 그 센싱신호가 신호선(3)을 통해 콘트롤러(7a)에 전송되는 과정이 반복됨에 따라 세탁이 수행된다.At this time, the various conditions in the washing tank 2 is often detected by the sensor of the sensor box 1 and washing is performed as the sensing signal is transmitted to the controller 7a through the signal line 3.

즉, 세탁시에는 세탁조(2)는 정지한채 펄세이터(8)만 회전하여 세탁이 행해지지만, 탈수시에는 상기 세탁조(2)가 고속회전 되도록 하므로써 원심력에 의해 탈수가 행해지게 된다.That is, in washing, washing is performed by rotating only the pulsator 8 while the washing tank 2 is stopped, but in dewatering, the washing tank 2 is rotated at a high speed so that dehydration is performed by centrifugal force.

일반적으로, 탈수기능을 수행하기 위한 세탁조(2)의 회전은 클러치(도시는 생략함)등의 작용에 의해 모터(6)의 회전시 구동축(11)의 회전력이 세탁조(2)에만 전달되므로써 행해진다.In general, the rotation of the washing tub 2 for performing the dehydration function is performed by the rotational force of the drive shaft 11 is transmitted only to the washing tub 2 when the motor 6 rotates by the action of a clutch (not shown). All.

그러나, 이와같은 종래의 세탁기는 탈수시 세탁조(2)가 회전하도록 되어 있으므로 센서박스(1)가 세탁조(2)에 장착될 경우 신호선(3)을 외부의 톤크롤러(7a)와 연결하기가 곤란하여 외조(10)에 장착할 수 밖에 없었다.However, such a conventional washing machine is difficult to connect the signal line 3 to the external tone crawler 7a when the sensor box 1 is mounted on the washing tank 2 because the washing tank 2 is rotated when dewatering. There was no choice but to mount it on the outer tub 10.

그러므로, 세탁물의 세탁상태를 직접 감지할 수 없어 간접적인 방법(예: 세탁물의 포량감지는 모터의 전류량 감지로, 세탁물 및 세탁수의 오염도 감지는 광센서의 광투과율 감지를 통해 간접적으로 측정한다)으로 감지하여 검출하였다.Therefore, it is not possible to directly detect the washing state of laundry, so indirect method (e.g., laundry quantity detection is measured by motor current amount, and contamination detection of laundry and washing water is indirectly measured by light transmittance detection of light sensor). It was detected by detecting.

이에따라 세탁물의 상태를 직접 감지할 수 없어 센서의 활용범위가 줄어들고, 세탁물의 상태를 간접적인 방법으로 감지하여 검출하는데 따른 검출오차가 커서 모드별 기능 수행에 있어서 세탁상태에 따른 정확한 기능수행이 될수 없는 등의 문제점이 있었다.Accordingly, the scope of use of the sensor is reduced because it is not able to directly detect the state of the laundry, and the detection error caused by detecting and detecting the state of the laundry indirectly is so large that it cannot be performed correctly according to the washing state in performing the functions by mode. There was a problem.

본 고안은 상기한 제반 문제점을 해결하기 위한 것으로서, 세탁조 내의 세탁물의 상태를 직접적으로 감지하고 그 신호를 검출하여 콘트롤러에 전달하므로써 검출시 그 정확도를 향상시킬 수 있는 전자동 세탁기의 세탁상태 검출장치를 제공하는데 그 목적이 있다.The present invention is to solve the above problems, and provides a washing state detection apparatus of a full automatic washing machine that can directly detect the state of the laundry in the washing tank and detect the signal and transmit the signal to the controller to improve its accuracy upon detection Its purpose is to.

상기한 목적을 달성하기 위해, 본 고안은 세탁조에 장착되는 센서박스와, 상기 센서박스의 신호선이 접촉되는 +,-접촉선을 가지며 세탁조 하부에 회전 가능하도록 설치되는 세탁조 연결부와, 상기 세탁조 연결부와 동일형상으로 세탁조 연결부의 하부에서 미끄럼 상대운동 하면서 전류가 도통하도록 된 외조연결부와, 상기 외조연결부에 접속되어 모터를 구동하기 위한 센서신호를 제어하는 콘트롤러로 구성되어 직접적으로 세탁물의 상태를 검출하도록 된 전자동 세탁기의 세탁상태 검출장치이다.In order to achieve the above object, the present invention has a sensor box mounted on the washing tank, a washing tank connection portion having a +,-contact line in contact with the signal line of the sensor box and rotatably installed at the lower portion of the washing tank, and the washing tank connecting portion; In the same shape, it consists of an outer tubular connection part which is connected to the outer tubular connection part and controls a sensor signal to drive a motor while the current is conducted while sliding relative movement in the lower part of the tub connection part to directly detect the state of the laundry. It is a washing state detection device of a fully automatic washing machine.

이하, 본 고안의 일실시예를 첨부도면 제2도 및 제3도를 참조하여 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 2 and 3 of the accompanying drawings.

제2도는 본 고안을 나타낸 종단면도이고 제3도는 제2도의 A-A선 횡단면도로서, 센서박스(1)가 세탁조(2)에 장착되고, 센서박스(1)의 신호선(3)이 접속되도록 원형의 +,-접촉선(4a, 4b)(5a, 5b)을 가지는 세탁조 연결부(4)가 세탁조(2)하부에 회전가능하도록 설치되며, 세탁조 연결부(4)와 동일형상으로 전도 및 미끄럼운동을 하는 외조연결부(5)가 세탁조 연결부(4)의 하부에 미끄럼 회전이 가능하게 설치되고, 외조연결부(5)와 신호선(3)에 의해 연결되어 센서박스(1)로 부터의 센싱신호를 처리하여 모터(6)를 구동하는 콘트롤러(7)가 설치되어 구성된다.2 is a longitudinal cross-sectional view of the present invention and FIG. 3 is a cross-sectional view taken along line AA of FIG. 2, in which a sensor box 1 is mounted on the washing tank 2 and a signal line 3 of the sensor box 1 is connected. Washing tub connecting portion (4) having +,-contact lines (4a, 4b) (5a, 5b) is installed to be rotatable under the washing tank (2), and conducts and slides in the same shape as the washing tank connecting portion (4) The outer tub connecting part 5 is slidably rotated at the lower part of the washing tub connecting part 4, and is connected by the outer tub connecting part 5 and the signal line 3 to process a sensing signal from the sensor box 1 to the motor. The controller 7 which drives (6) is provided and comprised.

이와같이 구성된 본 고안은 제2도 및 제3도에 나타낸 바와같이, 사용자의 선택에 의해 세탁기능이 수행될 때에는 사용자가 더러워진 세탁물을 세탁조(2)에 넣고 콘트롤러(7)의 시작버튼을 누르면 모터(6)는 서서히 회전하게 된다.2 and 3, when the washing function is performed by the user's selection, the user puts the dirty laundry into the washing tank 2 and presses the start button of the controller 7. 6) rotates slowly.

이때 세탁조(2)에 장착된 센서박스(1)의 각종센서가 작동되어 세탁상태를 검출한 후, 다시 콘트롤러(7)에 신싱신호가 피드백되면 콘트롤러(7)는 세탁물의 양과 오염도 등의 센싱신호에 실려온 각종 정보를 처리하여 세탁수의 양 및 세탁의 코스등을 결정하고 모터(6)에 신호를 인가하여 모터(6)가 알맞은 RPM으로 회전하도록 제어하게 된다.At this time, after the various sensors of the sensor box (1) mounted on the washing tank (2) is activated to detect the washing state, if the synching signal is fed back to the controller (7), the controller (7) senses the amount of laundry and the degree of contamination Various information carried in the process is processed to determine the amount of wash water and the course of washing, and to apply a signal to the motor 6 to control the motor 6 to rotate at an appropriate RPM.

이때, 센서박스(1)의 각종센서는 수시로 세탁조(2)내의 세탁상태를 검출하여 신호선(3)을 통해 콘트롤러(7)에 전송하는 과정을 반복하며 세탁을 수행하게 된다.At this time, the various sensors of the sensor box 1 performs the washing by repeatedly detecting the washing state in the washing tank 2 and transmitting the signal to the controller 7 through the signal line 3.

이렇게 세탁을 수행하는 과정에서 세탁조(2)는 정지한 상태에서 펄세이터(8)만이 회전하므로 센서박스(1)의 센서에 의해 검출된 센싱신호는 신호선(3)을 거쳐 세탁조 연결부(4)와 외조연결부(5)의 +,-접촉선(4a, 4b)(5a, 5b)을 통과하여 콘트롤러(7)에 전달된다.Since the washing tank 2 rotates only while the washing tank 2 is stopped in the process of washing, the sensing signal detected by the sensor of the sensor box 1 passes through the signal line 3 and the connecting portion 4 of the washing tank. It is transmitted to the controller 7 through the +,-contact lines 4a, 4b (5a, 5b) of the outer tubular connector 5.

또한, 세탁기의 탈수기능이 이루어질 때에는 일단 클러치 등의 동력 단속장치에 의해 모터(6)의 동력이 펄세이터(8)로 전달되지 않고 세탁조(2)로 전달되어 세탁조(2) 및 세탁조(2)에 결합된 세탁조 연결부(4)가 회전하게 된다.In addition, when the washing machine is dewatered, the power of the motor 6 is transmitted to the washing tank 2 instead of the pulsator 8 by a power control device such as a clutch, so that the washing tank 2 and the washing tank 2 are provided. Connecting to the washing tub 4 is rotated.

이 경우 세탁조(2)와 세탁조 연결부(4)의 회전각속도가 같으므로 신호선(3)의 꼬임이나 단락등이 발생하지 않게된다.In this case, since the rotational angular speeds of the washing tub 2 and the washing tub connecting portion 4 are the same, a kink or a short circuit of the signal line 3 does not occur.

한편, 세탁조 연결부(4) 및 외조 연결부(5)의 +,-접촉선(4a, 4b)(5a, 5b)은 제3도에 나타낸 바와같이, 고리모양으로 구성되어 있고 외조연결부(5)의 상면을 세탁조 연결부(4)의 하면이 미끄러지면서 회전하게 되는데 +,-접촉선(4a, 4b)(5a, 5b)이 원형으로 되어 두 연결부(4)(5)의 전기적 접속은 지속적으로 이루어 지게된다.On the other hand, the +,-contact lines (4a, 4b) (5a, 5b) of the washing tub connecting portion (4) and the outer tub connecting portion (5) is formed in a ring shape, as shown in Figure 3 and the outer tub connecting portion (5) The upper surface rotates while the lower surface of the tub connection part 4 slides, and the +,-contact lines 4a, 4b (5a, 5b) are circular, so that the electrical connection between the two connection parts 4, 5 is made continuously. do.

여기에서, 세탁조 연결부(4)와 외조연결부(5)의 +,-접촉선(4a, 4b)(5a, 5b) 사이에는 세탁조 연결부(4)의 회전 및 전기적 연결이 원활하게 이루어 지도록 전도성이 좋은 재질의 베어링(9)을 설치하여 사용할 수 있게 된다.Here, the conductive connection between the washing tub connecting portion 4 and the +,-contact lines (4a, 4b) (5a, 5b) of the tub connecting portion (5) so that the rotation and electrical connection of the washing tub connecting portion 4 is made smoothly The bearing 9 made of material can be installed and used.

이와같이 세탁조(2)내에 센서박스(1)가 장착되면 세탁물의 세탁상태를 간접적인 방법으로 감지할 때와는 달리 센서박스(1)의 센서가 세탁물의 상태를 직접 검출하므로써 검출오차를 대폭 감소시켜 세탁기의 세탁기능이 정확하게 수행될 수 있다.When the sensor box 1 is installed in the washing tank 2 as described above, unlike the case of indirectly detecting the washing state of the laundry, the sensor of the sensor box 1 directly detects the laundry state, thereby greatly reducing the detection error. The washing function of the washing machine can be performed accurately.

이상에서와 같이, 본 고안은 센서박스(1)가 세탁조(2)에 장착되고, 세탁조(2)와 함께 회전 가능하며 +,-접촉선(4a, 4b)(5a, 5b)을 가지는 세탁조 연결부(4) 및 외조(10)에 고정되는 외조연결부(5)가 설치되어 세탁 및 탈수시 신호선(3)이 보호되면서 세탁조(2)내의 상태를 직접검출하여 콘트롤러(7)에 전달하므로써 검출의 정확도를 대폭 향상시켜 세탁 및 탈수기능이 보다 정확하게 제어되므로 인해 세탁기의 성능을 향상시킨 매우 유용한 고안이다.As described above, the subject innovation is that the sensor box 1 is mounted on the washing tank 2, rotatable with the washing tank 2, the washing tank connection portion having +,-contact lines (4a, 4b) (5a, 5b) (4) and the outer tubular connection part 5 fixed to the outer tub 10 is installed so that the signal line 3 is protected during washing and dehydration while the state in the washing tub 2 is directly detected and transmitted to the controller 7 for accuracy of detection. It is a very useful design that improves the performance of the washing machine due to the drastically improved washing and dehydration function is more accurately controlled.
