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 상부방향으로 에어유츨구(21a)가 형성된 에어챔버(21)와, 상기 에어챔버(21)의 에어유출구(21a)에 일측단이 연결고정됨과 동시에 그 길이단은 상기 세탁조(3)의 외주연에 일체로 형성된 다수개의 고정돌기(3a)에 의해 일정간격으로 지지고정된 에어호스(22)와, 상기 에어호스(22)의 타측단과 연결고정되어서 에어챔버(21)을 통해 일정량 유입된 세탁수의 압력을 전달받아 압축되는 공기에 의해 작동되어 상기 급수수단(4)을 제어하도록 상기 세탁기본체(1)에 장착된 압력센서(23)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 upper direction and the air of the air chamber 21 One end is fixed to the outlet 21a and at the same time the length end is an air hose 22 which is supported and fixed at regular intervals by a plurality of fixing protrusions 3a integrally formed on the outer periphery of the washing tank 3, The washing machine body 1 is fixed to the other end of the air hose 22 and is operated by air compressed by receiving a pressure of the washing water introduced through the air chamber 21 to control the water supply means 4. It consists of a pressure sensor 23 mounted on).

이때, 상기 고정돌기(3a)는 상기 에어호스(22)가 착탈가능케 탄성체로 형성되어 있다.At this time, the fixing protrusion (3a) is formed of an elastic body so that the air hose 22 is detachable.

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) 및 탈수조(12)내에 세탁수가 급수되어 수위감지수단(20)의 에어챔버(21)에 일정량의 세탁수가 유입되면 이 유입된 세척수의 체적만큼 에어챔버(21)내의 공기는 압축되고, 상기 공기는 에어유출구(21a)에 일단이 연결된 에어호스(22)를 통해 압축됨과 동시에 그 에어호스(22)에 연결된 압력센서(23)를 눌려줌에 따라 상기 압력센서(23)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 the dewatering tank 12 and a predetermined amount of washing water flows into the air chamber 21 of the water level sensing means 20, the volume of the washing water flows into the air chamber 21. The air is compressed and the air is compressed through the air hose 22 having one end connected to the air outlet 21a and the pressure sensor 23 connected to the air hose 22 is pressed. By controlling the water supply means 4) in the washing tank 3 and the dewatering tank 12, the washing water is supplied by a predetermined amount.

이때, 상기 압력센서(23)에 의한 급수량의 측정은 압력센서(23)의 압축력에 따른 변화량이 미리 설정된 세탁수의 수압에 의한 공기압축력 프로세스에 의해 산출함으로써 급수량을 측정할 수 있게 되어 진다.At this time, the measurement of the water supply amount by the pressure sensor 23 can be measured by calculating the amount of change according to the compression force of the pressure sensor 23 by the air compression force process by the water pressure of the preset wash water.

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(23)는 원위치되고, 다시 세탁기본체(1)내에 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 the 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 main body 1 by the operation of the drainage means 14, the pressure sensor 23 returns to the original position. After the washing water rinsing and dewatering course, which is programmed in the washing machine body 1, new washing water is supplied to the water through the water supply means 4 and the rinsing course process is performed several times. (12) receives the power of the drive means (9) via the power transmission means 11 is rotated at a high speed to repeat the dehydration course for a certain time to repeat all course processes of the washing machine (for example, washing → rinsing → dehydration process) ) To complete the washing.

이때, 상기 수위감지수단(20)은 그 에어챔버(21)의 에어유출구(21a)가 상부쪽을 향하도록 형성되어 있고, 상기 에어유출구(21a)에 일단이 연결되는 에어호스(22)는 상기 세탁조(3)에 일체로 돌출형성된 고정돌기(3a)에 의해 견고히 지지고정되는 구조로 되어 있기 때문에 세탁조(3)가 심하게 진동되더라도 에어호스(22)는 세탁조(3)와 함께 진동되면서 에어챔버(21)로부터 탈착 및 꺽임이 방지되고, 또한 수위감지의 오동작이 미연에 방지되어지는 것이다.At this time, the water level detecting means 20 is formed so that the air outlet 21a of the air chamber 21 is directed upward, the air hose 22, one end of which is connected to the air outlet 21a is Since the washing tub 3 is firmly supported and fixed by the fixing protrusion 3a integrally formed in the washing tub 3, the air hose 22 vibrates with the washing tub 3 while the washing tub 3 is vibrated. Detachment and bending from 21) are prevented and malfunction of the water level detection is prevented in advance.

이상에서 설명한 바와 같이 본 고안에 의한 세탁기의 수위센서용 호스취부장치에 의하면, 수위감지수단의 에어호스가 세탁조에 장착되는 구조로 되어 있기 때문에 세탁조가 심하게 진동되더라도 에어챔버와 에어호스와의 연결부분이 탈착 및 꺽이지 않게 되어 수위감지의 오동작을 미연에 방지할 수 있음과 동시에 제품에 대한 신뢰감을 한층 더 향상시킬 수 있게 되는 효과를 갖는다.As described above, according to the hose mounting device for the water level sensor of the washing machine according to the present invention, since the air hose of the water level sensing means is mounted in the washing tank, the connection portion between the air chamber and the air hose even if the washing tank vibrates violently. It is possible to prevent the desorption and breakage of the water level detection in advance, and at the same time improve the reliability of the product.
