Description

세탁기의 절수장치Water Saving Device of Washing Machine

본발명은 세탁기에 관한 것으로서, 특히 소량의 세탁물을 세탁시에 세탁수사용을 극소화 하기 위한 세탁기의 절수 장치에 관한 것이다.The present invention relates to a washing machine, and more particularly to a water-saving device of the washing machine for minimizing the use of the washing water when washing a small amount of laundry.

종래의 세탁기 구조는 도 1 에 나타내었다.The conventional washing machine structure is shown in FIG.

상기 종래의 세탁기(1)는 세탁물을 허브(7)에 지지되어있는 세탁내조(3)에 담아 세탁수를 받은 뒤 모우터(11)와 클러치(12)의 작동에 의해 세탁내조(3)하부의 세탁날개(5) 및 회전날개(6)를 회전시켜서 세탁을 수행 하게 된다.The conventional washing machine (1) is to put the laundry in the washing tank (3) that is supported by the hub (7) to receive the wash water, the lower part of the washing tank (3) by the operation of the motor 11 and the clutch 12 The washing blades 5 and the rotary blades 6 are rotated to perform the washing.

세탁과정은 우선 세탁물을 세탁내조(3)에 넣고 세탁내조(3)에 세탁수가 급수 되면 세탁수는 세탁내조(3)의 통공(4)을 통해 세탁외조(2)로 흘러 나가게 되고 세탁외조(2)하단부 바깥쪽에 설치된 수위측정용 본체챔버(8)에 채워지는 상태가 된다.In the washing process, the laundry is first placed in the washing tub 3, and when the washing water is supplied to the washing tub 3, the washing water flows out into the washing tub 2 through the through hole 4 of the washing tub 3. 2) It is in a state filled with the body chamber for water level measurement (8) installed outside the lower end.

상기의 본체챔버(8)에 채워지는 적정한 수위레벨을 수위센서(도시안됨)가 판단하여 급수장치를 차단하게 된다.The water level sensor (not shown) determines the appropriate level of water to be filled in the main body chamber 8 to shut off the water supply.

상기의 급수가 완료되고 세탁행정이 시작되면 모우터(11)와 클러치(12)에 의해 세탁날개(5) 및 회전날개(6)가 정,역회전을 하면서 세탁을 하게 된다.When the above water supply is completed and the washing administration starts, the washing blade 5 and the rotary blade 6 are washed by the motor 11 and the clutch 12 while rotating forward and reverse.

상기와 같은 세탁과정중에 발생되는 세탁내조(3)와 세탁외조(2)하부의 세탁수 흐름을 설명 하기로 한다.The washing water flow of the washing inner tank 3 and the washing outer tank 2 generated during the washing process as described above will be described.

먼저, 세탁날개(5)의 저면부에는 여러개의 리브(10)들이 원형 또는 반원형상으로 형성되어 있다.First, a plurality of ribs 10 are formed in a circular or semicircular shape at the bottom of the washing blade 5.

상기 리브(10)들에 의해 세탁날개(5) 밑의 세탁수는 중심에서 외곽으로 원심력을 받게되고 외곽으로 유체속도가 빨라지므로 중심부의 압력이 높고 외곽이 낮아져 세탁수들이 외곽으로 밀려 나가게 된다.The wash water under the washing wing 5 is subjected to centrifugal force from the center to the outside by the ribs 10 and the fluid speed is increased to the outside, so the pressure of the center is high and the outside is lowered, so the washing water is pushed out.

상기의 과정에서 세탁내조(3)의 벽면에 수직방향으로 설치된 유로(15)로 세탁수가 올라가 실밥채집구(14)에 의해 세탁수가 걸러지게 된다.In the above process, the washing water rises to the flow path 15 installed in the vertical direction on the wall surface of the washing tub 3, and the washing water is filtered by the seam collecting hole 14.

상기 세탁날개(5)에 형성된 회전날개(6)에 의해 밀려나가는 세탁수는 유체의 연속성에 의해 중심부의 부족한 유량 만큼 회전날개(6)의 저부에 결합되어있는 허브(7)의 허브홀(9)을 통하여 세탁외조(2)바닥면에 차여 있는 세탁수를 흡입하는 상태가된다.The washing water pushed out by the rotary blade 6 formed in the washing blade 5 is the hub hole 9 of the hub 7 coupled to the bottom of the rotary blade 6 by a flow rate insufficient at the center due to the continuity of the fluid. Through the wash tub 2 is in a state to suck the wash water filled in the bottom surface.

상기와같은 허브홀(9)을 통한 흡입작용에 의해 세탁내조(3)와 세탁외조(2)의 수위는 내려가게 되고 다시 세탁내조(3)의 통공(4)을 통해 세탁외조(2)로 빠져 나가게 된다.By the suction action through the hub hole 9 as described above, the water level of the washing tub 3 and the washing tub 2 is lowered, and again to the washing tub 2 through the through hole 4 of the washing tub 3. You will exit.

상기와같은 일련의 과정은 세탁날개(5) 및 회전날개(6)가 회전 함으로서 발생되며 이들이 정지시에는 발생하지 않게 된다.Such a series of processes are generated by rotating the washing blade 5 and the rotary blade 6, they do not occur when stopped.

상기의 세탁과정이 완료되면 탈수과정이 시작 되어진다.When the washing process is completed, the dehydration process is started.

상기 탈수과정은 클러치(12)의 동작에의해 세탁날개(5)의 회전은 중지되고 세탁내조(3)가 회전을 하게된다.In the dehydration process, the rotation of the washing blade 5 is stopped by the operation of the clutch 12, and the washing inner tub 3 is rotated.

상기 세탁내조(3)는 세탁시보다 빠른 속도로 회전 되어지며 세탁내조(3)의 세탁물에 스며있는 세탁수를 여러개의 통공(4)을 통해 세탁외조(2)로 뽑아내게 되고 이들은 배수밸브(13)를 통해 외부로 배수 되어진다.The washing tub (3) is rotated at a faster speed than washing, and the wash water permeating the laundry of the washing tub (3) is drawn out to the washing tub (2) through a plurality of through holes (4) and these drain valves ( It is drained to the outside through 13).

상기와같은 종래의 세탁기는 세탁내조(3)와 세탁외조(2)사이에 세탁수가 항상 채워져 있어 실제 세탁하는 세탁수 이외의 물이 낭비되고 있다.In the conventional washing machine as described above, the washing water is always filled between the washing tub 3 and the washing tub 2, and water other than the washing water actually washed is wasted.

상기의 세탁수들은 초기에는 수위를 결정하고 세탁중에는 실밥채집구(14)로 이송을 하기 위해 대기하는 수량이 된다.The wash water is initially determined to the water level during the laundry is a quantity to wait for the transfer to the seam collecting port (14).

상기의 잉여 수량은 세탁내조(3)의 크기에 따라 약간의 차이는 있으나 도1에 표시된 수위(M)이상에서는 0.25 l/cm이고 수위(M)이하에서는 평균 1.2 l/cm의 양이 된다.The surplus water is slightly different depending on the size of the washing tub 3, but 0.25 l / cm above the water level (M) shown in Figure 1 and 1.2 l / cm on average below the water level (M).

따라서, 세탁시의 물의 낭비가 많았으며 세탁시간이 길어지게 되는 문제점 등을 가지고 있었다.Therefore, there was a lot of waste of water at the time of washing and the problem of longer washing time.

이러한 종래의 문제점 등을 해결보완 하기위하여 본발명은,In order to solve such a conventional problem, the present invention,

소량의 세탁물을 세탁시에 세탁시간의 단축과 물의 절약을 할수 있도록 하여 경제적인 세탁이 이루어질수 도록하는 목적을 제공 한다.When washing a small amount of laundry, it is possible to shorten the washing time and save water, thereby providing an economical laundry.

Drainage 110 and the hub hole 109 of the hub chamber 108 is supplied with the washing water rising from the washing outer tub 102 by the centrifugal force generated by the rotation of the rotary blade 106 to wash the inner tank ( Backflow prevention means installed to supply the washing water only in the direction of the rotary blade 106 of the 103, and in the washing inner tank 103, a certain amount of washing water is confined at the time of water supply and the washing water overflows when dewatering It was provided with a wash water storage means to be supplied to 102.

그리고, 상기의 역류방지 수단은 허브홀(109)로 유입되는 세탁수가 허브챔버(108)로의 유입이 용이토록하는 반면 허브챔버(108)내의 세탁수는 허브홀(109)로 역류 하지 못하 도록 하기 위하여 허브챔버(108)의 삽입공(111)에 후크(113)를 결합하여 개별적으로 개폐작용을 하는 다수개의 체크밸브(112)를 구비 하였다In addition, the countercurrent prevention means allows the washing water flowing into the hub hole 109 to be easily introduced into the hub chamber 108 while preventing the washing water in the hub chamber 108 from flowing back into the hub hole 109. In order to combine the hook 113 to the insertion hole 111 of the hub chamber 108 was provided with a plurality of check valves 112 for individually opening and closing action.

또한,상기의 체크밸브(112)는 허브챔버(108)에 방사상으로 형성된 여러개의 허브홀(109)을 동시에 개폐할수 있도록 한 개의 띠원판형 체크밸브(120)을 구비하였다.In addition, the check valve 112 is provided with a band disk-shaped check valve 120 to open and close the plurality of hub holes 109 radially formed in the hub chamber 108 at the same time.

그리고,상기의 세탁수보관수단은 세탁에 필요한 일정량의 세탁수가 일정수위만큼 세탁내조(103)에 차이도록 하기 위하여 세탁내조(103)의 저부에 결합되어 통공(104)들을 차단밀폐 시켜서 세탁수를 가둬 놓을수 있는 밀폐부재(116)를 구비하였다.And, the washing water storage means is coupled to the bottom of the washing tub 103 in order to make a certain amount of washing water required for washing to be different from the washing tub 103 by a certain level to block and seal the through-hole 104 to wash the water. It was provided with a sealing member 116 that can be trapped.

또한,상기의 세탁수보관수단은 세탁에 필요한 일정량의 세탁수가 일정수위 만큼 세탁내조(103)에 차이도록 하기 위하여 세탁내조(103)의 하측부에 형성된 일정구간(N)의 통공(104)들을 삭제하여 세탁수를 가둬 놓을수 있도록 구비하였다.In addition, the washing water storage means is a certain amount of washing water required for washing the predetermined number (N) through the holes 104 formed in the lower portion of the washing tub 103 in order to be different from the washing tub 103 by a certain level. Equipped to remove and lock up the wash water.

그리고,상기 밀폐수단은 허브(107와 세탁내조의 결합부에 누수를 방지 하기 위하여 세탁외조(102)의 플랜지(114)와 허브(107)의 사이에 시일링(115)을 더 구비하였다.The sealing means further includes a sealing ring 115 between the flange 114 of the laundry outer tub 102 and the hub 107 to prevent leakage of the coupling portion of the hub 107 and the washing tub.

또한,상기 세탁내조(103)를 일정한 속도로 회전시켜서 급수되는 세탁수를 세탁외조(102)로 넘치게한 뒤 세탁내조(103)의 부족한 양이 세탁외조(102)에 채워질때까지 급수를 계속하여 세탁외조(102)의 수위가 일정수위에 도달하면 센서에 의해 급수를 중단 시킬수 있는 급수수단을 더 구비하였다.In addition, by rotating the washing tub 103 at a constant speed to overflow the wash water supplied to the washing tub 102, the water is continued until the insufficient amount of the washing tub 103 is filled in the washing tub 102 It was further provided with a water supply means that can stop the water supply by the sensor when the water level of the washing tub 102 reaches a certain level.

이와같이된 본발명의 작용을 설명 하기로한다.The operation of the present invention thus described will be described.

먼저, 세탁동작과정을 보면 세탁물이 소량 투입되고 급수기 시작되면 세탁수가 세탁내조(103)로 들어오기 시작한다.First, looking at the washing operation process, when a small amount of laundry is added and the water supply starts, the washing water starts to enter the washing tank 103.

상기의 세탁수는 세탁내조(103)를 채우지만 도2의 K 높이 이하에서는 본체챔버(121)에 세탁수를 채울수 없게된다.The washing water fills the washing inner tank 103, but the washing water cannot be filled in the main body chamber 121 below the K height of FIG.

즉, 상기의 세탁내조(103)를 받쳐주고있는 허브(106)의 허브챔버(108)에는 체크 밸브(112)가 차단을 하고 있고 세탁내조(103)의 저면 플랜지(114)와 허브(107)의 상면 사이에는 시일링(115)이 설치되어 있으므로 누수가 있을수 없게된다.That is, the check valve 112 is blocked in the hub chamber 108 of the hub 106 supporting the washing tub 103, and the bottom flange 114 and the hub 107 of the washing tub 103 are blocked. Since the sealing ring 115 is installed between the upper surface of the can not be leaked.

또한, 상기 세탁내조(103)의 일정구간은 밀폐부재(116)에 의해 통공(104)들이 차단되어 있는 상태이므로 수위조절을 위한 본체챔버(121)에 세탁수를 공급할수 없는 상태가 된다.In addition, the predetermined period of the washing inner tub 103 is in a state in which the through holes 104 are blocked by the sealing member 116, so that washing water cannot be supplied to the main body chamber 121 for adjusting the water level.

따라서, 본발명에서는 허브(107)의 허브홀(109)주변부에 작은 배수공(110)을 천공시키고 있다.Therefore, in the present invention, the small drain hole 110 is drilled in the periphery of the hub hole 109 of the hub 107.

상기의 배수공(110)을 통하여 세탁수가 세탁외조(102)의 바닥면으로 흘러 나오게 되고 이 세탁수는 본체챔버(121)로 모이게 된다The wash water flows out to the bottom surface of the wash tub 102 through the drain hole 110, and the wash water is collected in the main body chamber 121.

그리고, 상기의 작은 배수공(110)으로 흘러나온 세탁수만으로도 세탁내조(103)와 세탁외조(102)사이의 부피가 적기 때문에 세탁내조(103)의 부피와 동일한 수위를 맞출수 있게된다.In addition, since only the wash water flowing out into the small drain hole 110 has a small volume between the washing tub 103 and the washing tub 102, the same water level as the volume of the washing tub 103 can be achieved.

그러나, 본발명의 급수 수위는 세탁내조(103)와 세탁외조(102)사이의 세탁수가 세탁내조(103)로 유입되므로 도2의 P위치까지 급수가 되면 중지되어진다.(종래에는 K위치까지 급수)However, the water supply level of the present invention is stopped when water is supplied to the P position of FIG. 2 since the washing water between the washing tub 103 and the washing tub 102 flows into the washing tub 103. rating)

세탁이 시작되면 세탁내조(103)와 세탁외조(102)사이의 세탁수는 회전날개(106)의 회전에 따른 흡입력으로 인해 허브챔버(108)의 허브홀(109)입구에 결합된 첵크밸브(112)를 밀은 뒤 허브챔버(108)내로 유입되면서 세탁내조(103)로 들어오게 된다.When the washing starts, the wash water between the washing tub 103 and the washing tub 102 is a check valve coupled to the inlet of the hub hole 109 of the hub chamber 108 due to the suction force caused by the rotation of the rotary blade 106 ( After pushing 112, it enters into the washing chamber 103 while flowing into the hub chamber 108.

상기의 세탁내조(103)로 들어온 세탁수는 체크밸브(112)에 의해 다시 세탁외조(102)로 나갈수 없으며 세탁내조(103)의 저부 플랜지(114)와 허브(107)의 상면 사이에 설치된 시일링(115)에의해 역류가 방지되어 세탁을 위해서만 사용되어진다.The washing water introduced into the washing tub 103 cannot go back to the washing tub 102 by the check valve 112 and is installed between the bottom flange 114 of the washing tub 103 and the upper surface of the hub 107. Backflow is prevented by the ring 115 and is used only for washing.

그리고, 상기의 체크밸브(112)는 후크(113)에 의해 허브챔버(108)내의 삽입공(111)으로 결합된 구성이므로 한 번 결합되면 분리가 안되기 때문에 견고한 구조를 갖게 된다.Since the check valve 112 is coupled to the insertion hole 111 in the hub chamber 108 by the hook 113, the check valve 112 has a rigid structure because it cannot be separated once combined.

상기의 과정에서 배수공(110)에서는 회전날개(106)가 회전하는 동안은 회전날개(106)쪽 하단이 허브(107)상면보다 속도가 빨라 압력이 낮아지게 되므로 세탁수를 허브챔버(108)내부로 뽑아 올릴수 있게된다.In the above process, while the rotor blade 106 is rotated in the drain hole 110, the lower edge of the rotor blade 106 side is faster than the hub 107 upper surface so that the pressure is lowered, the washing water inside the hub chamber 108 You can pull up.

그리고, 상기의 회전날개(106)가 정지 했을 경우에는 높이차에 의한 압력의 증가로인해 세탁수가 허브챔버(108)내에서 세탁외조(102)의 바닥면으로 흐르게 된다.Then, when the rotary blade 106 is stopped, the washing water flows to the bottom surface of the outer tub 102 in the hub chamber 108 due to the increase in pressure due to the height difference.

그러나, 상기 배수공(110)에 의한 세탁수의 유동량은 배수공(110)에 의한 유입량 보다 1/20이상 작기 때문에 세탁외조(102)로 세탁수가 역류되는 현상은 발생되지 않게된다.However, since the flow rate of the wash water by the drain hole 110 is 1/20 or more smaller than the inflow amount by the drain hole 110, the phenomenon that the wash water flows back into the wash tub 102 is not generated.

세탁과정이 진행되면 세탁내조(103)와 세탁외조(102)사이의 세탁수는 허브(107)의 하단부 L 높이까지 내려가게 되어 P위치에서 L위치까지의 세탁수가 절감되어진다.When the washing process proceeds, the washing water between the washing tub 103 and the washing tub 102 is lowered to the lower end L height of the hub 107, thereby reducing the washing water from the P position to the L position.

배수시에는 배수밸브(122)를 열고 세탁내조(103)를 느린 속도로 서서히 회전시키게 된다.When draining, the drain valve 122 is opened to slowly rotate the washing tub 103 at a slow speed.

상기 세탁내조(103)의 벽면은 아래에서 위로 갈수록 넓어지는 약간의 경사를 가지고 있으므로 세탁수는 벽면에서의 속도가 중심부에서의 속도보다 따른 상태가 되는 동시에 중심부보다 낮은 압력을 갖게 된다.Since the wall surface of the washing tub 103 has a slight inclination from the bottom to the top, the washing water has a pressure lower than that of the center at the same time as the speed at the wall is higher than the speed at the center.

따라서, 상기 중심부의 세탁수가 세탁내조(103)의 벽면으로 움직이면 벽면에서는 위로 올라가는 상태가 되어 세탁내조(103)의 통공(104)들을 통해 세탁외조(102)로 빠져나가 배수밸브(122)를 통해 외부로 배출되어진다.Therefore, when the washing water in the central part moves to the wall surface of the washing tub 103, the state is raised upward from the wall surface and exits to the washing tub 102 through the through holes 104 of the washing tub 103 through the drain valve 122. It is discharged to the outside.

그리고,상기 세탁내조(103)의 세탁수량이 줄어듬에 따라 세탁내조(103)의 회전속도를 증가시켜서 배수와 동시에 탈수를 진행하게된다.As the amount of washing water in the washing tub 103 decreases, the rotation speed of the washing tub 103 is increased to drain and simultaneously drain.

상기의 배수와 탈수시에는 세탁날개(105) 및 회전날개(106)가 정지해 있는 상태이기 때문에 세탁내조(103)에서 세탁외조(102)방향으로 계속해서 세탁수가 빠져나가는 과정이 진행된다.In the above drainage and dehydration, since the washing blade 105 and the rotary blade 106 are in a stopped state, a process of continuously washing the washing water from the washing inner tank 103 toward the washing outer tank 102 proceeds.

또한, 허브(107)의 저부는 중심부가 낮은 쪽으로 외곽에서 기울어져 있으므로 허브챔버(108)내에 세탁수가 남는 것을 방지 할수 있게된다.In addition, since the bottom of the hub 107 is inclined from the outside toward the lower portion of the hub 107, the washing water can be prevented from remaining in the hub chamber 108.

한편, 도5는 본발명의 급수 및 단수수단을 설명하기 위하여 나타낸 도면으로서On the other hand, Figure 5 is a view showing for explaining the water supply and singular means of the present invention

세탁내조(103)를 일정한 속도로 회전시키면서 급수를 하여 세탁수를 내조바닥면 에서 h0높이까지 받은 상태에서 세탁내조(103)가 회전을 하면 h1 의 높이까지 별면이 올러가 통공(104)들을 통해 세탁외조(102)로 넘치게 된다.While rotating the washing tub 103 at a constant speed, the water is supplied to the bottom of the tub, and the washing tub 103 is rotated in the state where the washing water is received from the bottom of the tub, whereby a separate surface is raised to the height of h1 through the through holes 104. The washing tub 102 is overflowed.

상기 세탁외조(102)로 넘친 물은 바닥에서 차오르면서 수위조절용 본체챔버(121)내부로 채워지게 되고 허브(107)의 하부에서 h2까지의 부피가 세탁내조(103)에서 모자란 물의 량(h1-h0)과 같아지면 수위센서(도시안됨)로부터 급수가 중단되어지게된다.The water overflowed to the washing tub 102 is filled from the bottom to the inside of the water level adjusting body chamber 121 and the volume of water from the bottom of the hub 107 to h2 is insufficient in the washing tub 103 (h1). -h0), the water supply from the water level sensor (not shown) is stopped.

상기의 상태에서 세탁이 시작되면 세탁외조(102)의 수위는 h2=0 까지 내려오게되고 세탁내조(103)는 목적했던 h1의 높이로 올라가게된다When washing starts in the above state, the water level of the washing tub 102 is lowered to h2 = 0 and the washing tub 103 is raised to the height of the desired h1.

이때, 배수공(110)은 상기한 구조의 크기보다 줄어들게 되어 세탁내조(103)의 잔수제거용으로만 사용을 하게된다.At this time, the drain hole 110 is reduced than the size of the structure is to be used only for removing the residual water of the washing inner tank (103).

그리고,본발명의 도6에 나타낸 바와같이 본발명에서 여러개로 개별적인 결합을 이루고 있는 첵크밸브(112)를 단일체의 띠원판형체크밸브(120)로 대체하여 사용 하여도 동일한 목적과 작용효과 등을 얻을수 있게된다.And, as shown in Figure 6 of the present invention, even if the check valve 112, which constitutes a plurality of individual combinations in the present invention can be replaced by a single band disk-shaped check valve 120, the same purpose and effect can be obtained. Will be.

이때, 상기 띠원판형 체크밸브(120)를 장착시에는 허브(107)의 허브챔버(108)도 원통형상으로 가공하여야 한다.At this time, when the band disk-shaped check valve 120 is mounted, the hub chamber 108 of the hub 107 should also be processed into a cylindrical shape.

또한,도7에 나타낸 바와같이 본발명의 세탁내조(103)의 통공(104)들을 막기 위하여 사용되는 밀폐부재(116)대신에 세탁내조(103)자체에 일정구간(N)을 통공(104)이 없는 밀폐된 상태로 가공하여 사용 하여도 본발명에 부합되어진다.In addition, instead of the sealing member 116 used to prevent the through holes 104 of the washing tub 103 of the present invention, as shown in Figure 7 through a certain period (N) through the washing tub 103 itself (104). Even if it is processed and used in a sealed state, it is in accordance with the present invention.

이와같이된 본발명은 일반가정에서 사용자들이 보통 수행하는 세탁량에 해당하는 소량(3kg내외)의 세탁량을 세탁함에 있어서 옷감대 세탁수량의 비율을 줄이지 않고 잉여 세탁수의 양을 절감하여 세탁성능은 동일한 반면 세탁수량은 30-40%를 절감할수 있게된다.In the present invention, in the case of washing a small amount (about 3kg) of laundry, which is usually performed by users in a general household, the washing performance is the same by reducing the amount of excess washing water without reducing the ratio of the cloth washing amount. Washing quantity can save 30-40%.

그리고, 세제량도 수량에 비례하여 30-40%가 줄어 들기 때문에 에너지절약과 신속한 세탁이 이루어질수 있는 유용한 효과를 갖는다.In addition, since the amount of detergent is reduced in proportion to the amount of 30-40% has the useful effect that can be energy-saving and rapid washing.
