In addition, the same code | symbol is attached | subjected to the same part as FIG. 1, and the overlapping description is abbreviate | omitted.
제2도 및 제3도에 도시한 바와 같이, 세탁기본체(1)내에 다수개의 서스펜션 바(2)를 매개로 일정 높이에 매달려서 세탁 및 탈수시 진동이 방지되도록 장착된 세탁조(3)와, 상기 세탁조(3)의 외측 바닥면에 장착되어 전원을 인가받아 구동되는 구동수단(9)과, 상기 구동수단(9)으로부터 벨트(10)를 매개로 구동력을 전달받아 구동되도록 상기 세탁조(3)의 외측 바닥면에 장착된 동력전달수단(11)과, 상기 동력전달수단(11)의 회전에 의한 원심력에 의해 세탁물을 탈수하도록 상기 세탁조(3)내에 회전가능케 장착된 탈수조(12)와, 상기 동력전달수단(11)을 매개로 구동수단(9)의 동력을 전달받아 반전되면서 탈수조(12)내에 수용된 세탁수에 수류를 형성시켜 세탁을 행하도록 상기 탈수조(12)내의 바닥면에 회전가능케 장착된 펄세이터(13)와, 상기 세탁조(3)에 장착되어 세탁조(3)내에 급수되는 세탁수의 압력을 급수수단(4)에 전달하여 수위를 제어하는 수위감지수단(20)으로 이루어져 있다.As shown in FIG. 2 and FIG. 3, the washing tank 3 mounted on the washing machine main body 1 by a plurality of suspension bars 2 so as to prevent vibration during washing and dehydration, and A driving means 9 mounted on an outer bottom surface of the washing tank 3 and driven by power, and receiving the driving force from the driving means 9 through the belt 10 to be driven. A power transmission means (11) mounted on an outer bottom surface, a dehydration tank (12) rotatably mounted in the washing tank (3) so as to dehydrate laundry by centrifugal force by the rotation of the power transmission means (11), and Rotates on the bottom surface of the dehydration tank 12 to perform washing by forming a water flow in the wash water contained in the dehydration tank 12 while receiving power from the driving means 9 through the power transmission means 11. The pulsator 13 and the washing tank 3, Takjo consists of a water level sensing means (20) for controlling the water level by passing the pressure of the wash water to the water supply means 4 are in the water supply (3).
즉, 상기 수위감지수단(20)은 상기 세탁조(3)의 외측 하단과 연통되게 장착되고 그 측방향으로 에어유출구(21a)가 형성된 에어챔버(21)와, 상기 에어챔버(21)의 에어유출구(21a)에 장착되어서 세탁수의 수압에 의한 압축공기에 의해 급수수단(4)을 제어하여 세탁조(3)내의 수위량을 조절하는 압력센서(22)로 이루어져 있다.That is, the water level detecting means 20 is mounted in communication with the outer lower end of the washing tank 3, the air chamber 21 is formed with an air outlet 21a in the lateral direction, and the air outlet of the air chamber 21 And a pressure sensor 22 mounted on the 21a to control the water supply means 4 by the compressed air by the water pressure of the washing water to adjust the water level in the washing tank 3.
한편, 도면중 미 설명부호 14는 배수수단이고, 15는 톱카바부재이며, 16은 뚜껑이다.In the drawings, reference numeral 14 denotes a drain means, 15 a top cover member, and 16 a lid.
다음에는, 이와 같이 구성된 본 고안의 작용 및 효과를 설명한다.Next, the operation and effects of the present invention configured as described above will be described.
제2도 및 제3도에 도시한 바와 같이, 세탁기는 탈수조(12)내에 세탁물 및 세제를 일정량 투입하고 전원을 인가시킴과 동시에 세탁조건을 선택하게 되면, 급수수단(4)을 통하여 온수 또는 냉수가 선택적으로 상기 탈수조(12)내에 급수된다.As shown in FIG. 2 and FIG. 3, when the washing machine puts a certain amount of laundry and detergent into the dehydration tank 12 and applies power to the washing machine and selects washing conditions, hot water or water is supplied through the water supply means 4. Cold water is optionally supplied to the dewatering tank 12.
즉, 상기 세탁조(3)내에 세탁수가 급수되어 수위감지수단(20)의 에어챔버(21)내에 일정량의 세탁수가 유입되면 이 유입된 세척수의 체적만큼 에어챔버(21)내의 공기는 압축되고, 상기 공기는 에어유출구(21a)에 직접 취부된 압력센서(22)를 눌려줌에 따라 상기 압력센서(22)는 급수수단(4)을 제어하게 되므로써 세탁조(3) 및 탈수조(12)내에는 일정량 프로세스된 값만큼 세탁수가 급수되어 진다.That is, when washing water is supplied into the washing tank 3 and a predetermined amount of washing water flows into the air chamber 21 of the water level sensing means 20, the air in the air chamber 21 is compressed by the volume of the introduced washing water. As the air presses the pressure sensor 22 directly attached to the air outlet 21a, the pressure sensor 22 controls the water supply means 4, so that the washing tank 3 and the dewatering tank 12 have a predetermined amount. Washing water is supplied by the processed value.
이때, 상기 압력센서(22)에 의한 급수량의 측정은 압력센서(22)의 압축력에 따른 변화량을 미리 설정된 세탁수의 수압에 의한 공기압축력 프로세스에 의해 산출함으로써 급수량을 측정할 수 있게 되어 있다.At this time, the measurement of the amount of water supplied by the pressure sensor 22 is able to measure the amount of water supply by calculating the amount of change according to the compressive force of the pressure sensor 22 by the air compression force process by the water pressure of the washing water set in advance.
한편, 상기와 같이 일정량의 세탁수가 급수되면 시간 프로세스에 의해 수초 후 구동수단(9)의 작동에 따라 동력전달수단(11)을 매개로 탈수조(12)내에 장착된 펄세이터(13)가 반전을 행하여 수류를 형성시켜 세탁을 행하게 된다.On the other hand, when a certain amount of washing water is supplied as described above, the pulsator 13 mounted in the dehydration tank 12 is inverted through the power transmission means 11 according to the operation of the driving means 9 after a few seconds by a time process. To form a stream of water to wash.
그리고, 상기 세탁코스 공정에 따라 세탁이 완료되어 배수수단(14)의 작동에 의해 세탁수(예컨대, 오염수)가 세탁기본체(1)내에서 외부로 배수되면, 압력센서(22)는 원위치되고, 다시 세탁기본체(1)에 프로그램화된 세탁→헹굼→탈수코스 공정에 의해 급수수단(4)을 통하여 상술한 바와 같이 새로운 세탁수가 급수되어짐과 동시에 헹굼코스 공정을 수회 행한 후, 상기 탈수조(12)가 구동수단(9)의 동력을 동력전달수단(11)을 매개로 전달받아 고속으로 회전됨으로써 탈수코스 공정을 일정시간동안 반복하여 세탁기의 모든 코스공정(예컨대, 세탁→헹굼→탈수공정)을 거쳐 세탁을 완료하게 된다.When washing is completed according to the washing course process and the washing water (eg, contaminated water) is drained to the outside in the washing machine body 1 by the operation of the drainage means 14, the pressure sensor 22 is returned to its original position. After the washing → rinsing → dehydration course process programmed in the washing machine main body 1 again, the new washing water is supplied to the water through the water supply means 4 and the rinsing course process is performed several times. 12) the power of the driving means 9 is transmitted through the power transmission means 11 to rotate at a high speed, so that the dehydration course is repeated for a predetermined time and all the course processes of the washing machine (for example, washing → rinsing → dehydration) After washing is completed.
한편, 상기 수위감지수단(20)은 그 에어챔버(21)의 에어유출구(21a)에 압력센서(22)가 직접 취부되는 구조로 되어 있기 때문에 종래와 같이 에어호스의 취부에 따른 조립불량을 없앨 수 있으며, 또한 세탁조(3)가 심하게 진동시 세탁조(3)와 함께 진동되는 에어챔버(21)로부터 압력센서(22)가 탈착될 염려가 없음은 물론, 수위감지의 오동작 및 수위감지의 부정확도를 미연에 방지할 수 있는 것이다.On the other hand, since the water level detecting means 20 has a structure in which the pressure sensor 22 is directly attached to the air outlet 21a of the air chamber 21, eliminating the assembly failure caused by the mounting of the air hose as in the prior art. In addition, there is no fear that the pressure sensor 22 may be detached from the air chamber 21 which vibrates with the washing tank 3 when the washing tank 3 vibrates violently, as well as the malfunction of the water level detection and the inaccuracy of the water level detection. This can be prevented in advance.
이상에서 설명한 바와 같이 본 고안에 의한 세탁기의 수위감지취부장치에 의하면, 수위감지수단에서 에어호스를 없애고 에어챔버에 직접 압력센서를 취부하는 구조로 되어 있기 때문에 조립불량을 없앨 수 있음은 물론, 수위감지의 오동작 및 수위감지의 부정확도를 미연에 방지할 수 있음과 동시에, 제품에 대한 신뢰감을 한층 더 향상시킬 수 있는 효과를 갖는다.As described above, according to the water level detecting unit of the washing machine according to the present invention, since the air hose is removed from the water level detecting means and a pressure sensor is directly attached to the air chamber, the assembly failure can be eliminated. It is possible to prevent the malfunction of the detection and the inaccuracy of the water level detection in advance, and at the same time, it has the effect of further improving the reliability of the product.
