즉, 세탁기(1)의 아웃터브(3) 일측에 세탁수의 수위를 감지하도록 수위감지센서(9)와 연결관(8)으로 연결된 에어쳄버(7)와, 상기 에어쳄버(7)의 연장관(10)과 결합하는 에어쳄버캡(11)과, 상기 에어챔버캡(11)이 결합된 아웃터브(3)의 저면에 세탁수를 배출시키기 위하여 형성되는 배수공(12)과, 상기 배수공(12)으로부터 세탁수를 공급받는 배수하우징(13)에 형성된 배수관(21)과, 상기 배수관(21)을 아웃터브(3)에 결합시키기 위하여 아웃터브(3)에 형성된 나사공(13)과, 상기 나사공(13)과 일치되도록 배수관(21)의 플랜지(23)에 형성된 삽입공(24)과, 상기 삽입공(24)으로 삽입되어 나사공(13)과 체결되는 비스(28)와, 상기 비스(28)의 체결에 의해 배수관(21)으로 공급된 세탁수를 개폐밸브(18)의 개폐작용에 의해 공급받는 배수호스(22)와, 상기 배수호스(22)로 세탁수를 공급하기 위하여 개폐밸브(18)를 작동시키는 피봇링크(15)와 연결된 배수모우터(14)를 구비한 구성이다.That is, the air chamber 7 connected to the water level sensor 9 and the connection pipe 8 so as to detect the level of the wash water on one side of the tub 3 of the washing machine 1, and the extension pipe of the air chamber 7 Air chamber cap 11 to be coupled to the (10), a drain hole (12) formed to discharge the wash water on the bottom surface of the outer tub (3) to which the air chamber cap 11 is coupled, and the drain hole (12) Drain pipe 21 formed in the drainage housing 13 receives the wash water from the), the screw hole 13 formed in the outer tub 3 to couple the drain pipe 21 to the outer tub 3, and An insertion hole 24 formed in the flange 23 of the drain pipe 21 so as to coincide with the screw hole 13, a screw 28 inserted into the insertion hole 24 and fastened to the screw hole 13, and Supplying the wash water to the drain hose 22, which receives the wash water supplied to the drain pipe 21 by the fastening of the vis 28 by the opening / closing action of the opening / closing valve 18, and the drain hose 22. To a structure having a multiple Motor 14 is connected to the pivot link 15 to operate the closing valve (18).
상기와 같은 종래 세탁기(1)의 구성에 따른 작용효과를 설명하면 다음과 같다.Referring to the operation and effect according to the configuration of the conventional washing machine 1 as described above are as follows.
먼저, 세탁기(1)는 모우터(6)가 구동축(5)을 회전시키고 상기 구동축(5)은 인너터브(2)의 저부에 결합된 세탁날개(4)를 회전시킴으로써 인너터브(2) 내부에 있는 세탁물을 세탁하게 된다.First, in the washing machine 1, the motor 6 rotates the driving shaft 5, and the driving shaft 5 rotates the washing blade 4 coupled to the bottom of the inner tub 2, thereby forming the inner tub 2. You will be washing the laundry in.
그리고, 상기 세탁물을 세탁시 배수공정때에는 배수모우터(14)가 작동하여 배수공(12)으로부터 공급받은 세탁수를 배수호스(22)에 의해 세탁기(1)의 외부로 배출하게 된다.In addition, during the washing process of the laundry, the draining motor 14 operates to discharge the washing water supplied from the drain hole 12 to the outside of the washing machine 1 by the drain hose 22.
이때, 상기 세탁수는 전원이 공급된 배수모우터(14)가 작동하여 피봇링크(15)를 당기게 되면 상기 피봇링크(15)와 제1탄성부재(16)로 연결된 결합관(20) 내부에 있는 개폐밸브(18)는 배수모우터(14) 방향으로 후퇴하게 된다.At this time, the washing water is supplied to the inside of the coupling pipe 20 connected to the pivot link 15 and the first elastic member 16 when the power supply drainage motor 14 is operated to pull the pivot link 15. The open / close valve 18 is retracted toward the drain motor 14.
그리고, 상기 개폐밸브(18)의 후퇴로 인하여 배수호스(22)의 입구가 개방되고 상기 개방된 배수호스(22)의 입구로 배수관(21)으로부터 세탁수가 공급되어 세탁기(1)의 외부로 세탁수를 배출시키게 된다. In addition, the inlet of the drain hose 22 is opened due to the retraction of the on-off valve 18, and the washing water is supplied from the drain pipe 21 to the inlet of the open drain hose 22 to be washed outside of the washing machine 1.

즉, 상기의 에어챔버(7)에는 일정량의 공기가 차 있고 상기 에어챔버(7)의 공기에는 세탁수의 수위에 따른 압력이 작용하게 된다.That is, the air chamber 7 is filled with a predetermined amount of air, and the pressure of the water level of the washing water acts on the air of the air chamber 7.
그리고, 상기 에어챔버(7) 내부의 공기로 전달된 압력은 에어챔버(7)의 상부와 연결관(8)로 연결된 수위감지센서(9)로 전달됨으로써 공기의 압력을 감지하여 세탁수의 수위를 감지하게 된다.In addition, the pressure delivered to the air inside the air chamber 7 is transferred to the water level sensor 9 connected to the upper portion of the air chamber 7 and the connection pipe 8 to sense the pressure of the air to level the wash water. Will be detected.
그러나, 상기와 같이 세탁수의 수위를 감지하는 에어챔버(7)의 저부에는 제작공정시 에어챔버(7)를 형성하기 위한 금형이 빠져나오는 연장관(10)이 형성되었다.However, an extension tube 10 through which a mold for forming the air chamber 7 exits is formed at the bottom of the air chamber 7 for detecting the level of the wash water as described above.
그리고, 상기 연장관(10)으로 세탁수가 빠져나가는 것을 방지하기 위해 에어챔버캡(11)을 형성하여 에어챔버(7)의 연장관(10)과 용착하여 결합하였었다.In order to prevent the wash water from escaping into the extension tube 10, an air chamber cap 11 was formed and welded to the extension tube 10 of the air chamber 7.
또한, 상기 세탁수를 세탁기(1)의 외부로 배수시키기 위하여 배수공(12)을 따로 제작하였었다.In addition, to drain the wash water to the outside of the washing machine (1) was made separately to the drain hole (12).
따라서, 상기 에어챔버캡(11)을 형성하는 공정과 상기 연장관(10)과 에어챔버캡(11)을 결합시키는 용착공정 및 상기 배수공(12)을 따로 형성해야 하는 제작공정등으로 인하여 아웃터브(3)를 제작시 불편하고 번거로운 문제점등을 가지고 있었다.Therefore, due to the process of forming the air chamber cap 11, the welding process of coupling the extension tube 10 and the air chamber cap 11, and the manufacturing process of forming the drain hole 12 separately, etc. 3) had an uncomfortable and cumbersome problem when making.
이러한 종래의 문제점 등을 해결 보완하기 위한 본 발명의 목적은,An object of the present invention for solving and solving such a conventional problem,

또한, 상기 연장관(112)과 배수관(134)의 결합부위로 세탁수가 누수되는 것을 방지하기 위하여 연장관(112)과 배수관(134)의 플랜지(135) 사이에 결합되는 밀폐부재(144)를 더 구비하였다.In addition, the sealing member 144 is further provided between the extension pipe 112 and the flange 135 of the drain pipe 134 in order to prevent the wash water leakage to the coupling portion of the extension pipe 112 and the drain pipe 134. It was.
이와같이된 본 발명의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention as described above is as follows.
먼저, 세탁기(101)는 모우터(106)가 구동축(105)을 회전시키고 상기 구동축(105)은 인너터브(102)의 저부에 결합된 세탁날개(104)를 회전시킴으로써 인너터브(102) 내부에 있는 세탁물을 세탁하게 된다.First, in the washing machine 101, the motor 106 rotates the drive shaft 105, and the drive shaft 105 rotates the washing blade 104 coupled to the bottom of the inner tub 102, thereby forming the inner tub 102. You will be washing the laundry in.
상기와 같은 세탁기(101)는 아웃터브(103) 일측에 형성된 에어챔버(111)에 의해 세탁수의 수위를 감지하게 된다.The washing machine 101 as described above detects the level of the wash water by the air chamber 111 formed on one side of the tub 103.
즉, 상기의 에어챔버(111)로 공급된 세탁수는 에어챔버(111) 내부에 있는 공기로 세탁수의 수위에 따른 압력을 전달하게 된다.That is, the wash water supplied to the air chamber 111 transmits the pressure according to the level of the wash water to the air inside the air chamber 111.
그리고, 상기 세탁수의 압력을 전달받은 공기는 연결관(107)을 통과하여 수위감지센서(108)로 압력을 전달함으로써 수위감지센서(108)에 의해 세탁수의 수위가 감지된다.Then, the air received the pressure of the wash water is passed through the connection pipe 107 to transfer the pressure to the water level sensor 108, the water level of the wash water is sensed by the water level sensor 108.
상기와 같이 수위를 감지하기 위하여 세탁수를 공급받는 에어챔버(111)에는 아웃터브(103) 제작시 형성되는 연장관(112)으로 배수호스(133)와 개폐밸브(125)가 조립된 배수하우징(131)이 결합되어 배수공정을 하게 된다.In order to detect the water level as described above, the air chamber 111 is supplied with the washing water to the extension tube 112 formed when manufacturing the outer tub 103, the drain hose 133 and the opening and closing valve 125 assembled as a drain housing ( 131) is combined to the drainage process.
즉, 상기의 연장관(112)으로 공급된 세탁수는 배수하우징(131)의 배수관(134)으로 공급되고 상기 배수관(134)으로 공급된 세탁수는 개폐밸브(125)의 개폐작용에 의해 배수호스(133)로 공급되어 세탁기(101)의 외부로 배출된다.That is, the wash water supplied to the extension pipe 112 is supplied to the drain pipe 134 of the drain housing 131 and the wash water supplied to the drain pipe 134 is drained by an opening / closing action of the on / off valve 125. Supplied to 133 is discharged to the outside of the washing machine 101.
그리고, 상기 배수호스(133)의 입구를 개폐시키는 개폐밸브(125)는 배수모우터(121)가 작동하여 피봇링크(122)를 당기게 되면 상기 개폐밸브(125)는 제1탄성부재(123)에 의해 피봇링크(122)와 연결되어 있으므로 배수모우터(121) 방향으로 후퇴하게 된다.Then, the opening and closing valve 125 for opening and closing the inlet of the drain hose 133 is the opening and closing valve 125 is the first elastic member 123 when the drain motor 121 is operated to pull the pivot link 122. It is connected to the pivot link 122 by the retracted in the direction of the drain motor 121.
이때, 상기 개폐밸브(125)가 후퇴하게 되면 상기 배수호스(133)의 입구가 개방되어 배수관(134)으로 부터 세탁수를 공급받아 외부로 세탁수를 배출시키게 되는 것이다.At this time, when the on-off valve 125 is retracted, the inlet of the drain hose 133 is opened to receive the wash water from the drain pipe 134 to discharge the wash water to the outside.
또한, 상기 세탁수의 배수가 완료되면 배수모우터(121)가 작동을 멈추어 당겼던 피봇링크(122)를 놓게되고 상기 개폐밸브(125)를 당기는 피봇링크(122)의 힘이 없어지면 제2탄성부재(124)의 복원력으로 인하여 개폐밸브(125)는 배수호스(133)의 입구를 다시 밀폐시키게 된다.In addition, when the drainage of the wash water is completed, the draining motor 121 releases the pivot link 122 that has stopped the operation, and when the force of the pivot link 122 pulling the on / off valve 125 disappears, the second elasticity is lost. Due to the restoring force of the member 124, the on-off valve 125 closes the inlet of the drain hose 133 again.
한편, 상기 연장관(112)으로 부터 세탁수를 공급받는 배수관(134)은 결합구(141)의 체결력에 의해 연장관(112)과 결합하여 세탁수를 세탁기(101)의 외부로 배수시키게 된다.On the other hand, the drain pipe 134 receiving the wash water from the extension pipe 112 is coupled to the extension pipe 112 by the fastening force of the coupling port 141 to drain the wash water to the outside of the washing machine 101.
즉, 상기 연장관(112)과 배수관(134)에 형성된 플랜지(135)가 접촉하고 상기 플랜지(135)로 걸림턱(142)이 형성된 결합구(141)가 결합하게 된다.That is, the flange 135 formed on the extension pipe 112 and the drain pipe 134 is in contact with each other, and the coupling hole 141 having the locking jaw 142 is coupled to the flange 135.
그리고, 상기 결합구(141)에 형성된 암나사부(143)와 연장관(112)에 형성된 숫나사부(113)가 회전하며 체결하게 되어 연장관(112)과 배수관(134)이 결합하게 되는 것이다.In addition, the female screw portion 143 and the male screw portion 113 formed on the extension pipe 112 are rotated and coupled to each other so that the extension pipe 112 and the drain pipe 134 are coupled to each other.
이때, 상기 결합구(141)에 형성된 걸림턱(142)에 의해 배수관(134)의 플랜지(135)가 밀착되면서 연장관(112)과 배수관(134)을 밀착결합시키게 되는 것이다.At this time, the flange 135 of the drain pipe 134 is in close contact with the engaging jaw 142 formed in the coupling hole 141 to closely couple the extension pipe 112 and the drain pipe 134.
또한, 상기 연장관(112)과 배수관(134)의 플랜지(135) 사이에 결합된 밀폐부재(144)에 의해 결합부위로 세탁수가 누수되는 것이 방지된다.In addition, by the sealing member 144 coupled between the extension pipe 112 and the flange 135 of the drain pipe 134 to prevent the wash water leakage to the coupling portion.
상기와 같이 세탁수의 수위를 감지하고 배수공정을 하는 본 발명 에어챔버(111)가 형성된 아웃터브(103)에는 연장관(112)으로 종래의 에어챔버캡을 형성하여 밀폐시킬 필요가 없게 된다.As described above, the outer tube 103 in which the air chamber 111 of the present invention detects the water level of the washing water and performs the drainage process does not need to be sealed by forming a conventional air chamber cap with an extension tube 112.
즉, 상기 배수하우징(131)에 조립된 배수호스(133)의 입구를 밀폐시키는 개폐밸브(125)에 의해 밀폐가 되기 때문에 종래의 에어챔버캡과 용착공정이 필요가 없는 것이다. That is, since it is sealed by the opening and closing valve 125 for sealing the inlet of the drain hose 133 assembled to the drain housing 131, there is no need for a conventional air chamber cap and welding process.
또한, 상기 아웃터브(103)에 세탁수를 배수시키기 위한 배수공을 따로 형성할 필요도 없게 된다.In addition, it is not necessary to form a separate drain hole for draining the wash water in the outer tub (103).
이와같이된 본 발명은 에어챔버의 연장관에 숫나사부를 형성하고 배수하우징의 배수관에 플랜지를 형성하여 암나사부가 형성된 결합구로 연장관과 배수관을 결합함으로써 에어챔버의 연장관으로 배수하우징의 배수관을 결합하여 에어챔버로 공급된 세탁수를 배수하우징의 배수호스에 의해 외부로 배수시킬 수 있는 동시에 에어챔버와 연결관으로 연결된 수위감지센서에 의해 세탁수의 수위를 감지할 수 있는 유용한 효과를 갖는다.According to the present invention, a male screw portion is formed in the extension pipe of the air chamber, and a flange is formed in the drain pipe of the drainage housing. The wash water can be drained to the outside by the drainage hose of the drainage housing, and at the same time, the water level sensor connected to the air chamber and the connection pipe has a useful effect of detecting the wash water level.
