본 고안은 세탁기의 투웨이(Two-Way)펌프내에서 유체통로를 개폐함에 제공되는 개폐볼에 관한 것이로, 특히 볼의 외 표면을 탄성물질로 구성하여 이동시 유체통로와의 마찰소음이 없게한 세탁기의 투웨이 펌프용 개폐볼에 관한 것이다.The present invention relates to an opening / closing ball provided to open and close a fluid passage in a two-way pump of a washing machine. In particular, the outer surface of the ball is made of an elastic material so that there is no friction noise with the fluid passage during movement. It relates to a two-way pump opening and closing ball.

일반적으로 세탁기에는 세탁용수를 배수하거나 혹은 헹굼용으로 순환시킴에 사용되는 투웨이펌프가 구비되어 있다. 이에 대한 구조 일예를 제1도에 도시하였다.In general, a washing machine is provided with a two-way pump used for draining washing water or circulating for rinsing. An example of the structure thereof is shown in FIG.

제1도는 투웨이펌프의 분리사시도로서, 그 구성을 간단하게 설명하면 다음과 같다. 투웨이펌프는 적어도 2개의 유체통로를(4a, 4b)가 대향 설치되어 있으며, 내부에는 소정넓이의 수용실(4)가 형성되어 있는 케이싱(3)과, 그 케이싱(3)을 착탈 가능하게 덮도록 설치되어 폐쇄된 수용실(4)를 형성되게 하고, 중앙에는 수용실(4)와 연락되는 유체유입공(2)가 형성된 덮개판(1)을 구비하고 있다.1 is an exploded perspective view of a two-way pump, the configuration of which is briefly described as follows. The two-way pump has at least two fluid passages 4a and 4b opposed to each other, and includes a casing 3 having a storage chamber 4 having a predetermined width therein and a detachable cover of the casing 3. The cover plate 1 is formed so as to form a closed accommodating chamber 4, and a fluid inlet hole 2 in contact with the accommodating chamber 4 is formed at the center thereof.

상기 유체통로들(4a, 4b) 의 사이에는 유동가능하게 위치된 개폐볼(8)이 위치되어 있고, 그 개폐볼(8)의 직상방에는 개폐용볼(8)이 어느 하나의 유체통로들(4a, 4b)를 선택적으로 개폐함에 필요한 유통압력을 부여하는 구동휀(7)이 설치되어 있다. 도면부호(9)는 가이드판이다.Between the fluid passages 4a and 4b, an opening and closing ball 8 is positioned to be flowable, and an opening and closing ball 8 is directly above the opening and closing ball 8 so that any one of the fluid passages ( A drive wheel 7 is provided to impart a flow pressure necessary for selectively opening and closing 4a and 4b. Reference numeral 9 is a guide plate.

이러한 구성으로, 미도시한 모우터구동으로 인한 구동휀(7)이 구동하면, 이때의 구동력이 유체유입공(2)를 통해 수용실(4)의 내부로 기히 유입되어져 있던 세탁용수에 가해지게 하여 세탁용수가 구동압력을 갖고 임의 방향으로 이송되게 한다. 이때의 유체압력은 개폐볼(8)에 가해지게 되고, 개폐볼(8)은 그 유체압력이 미치는 방향에 따라서 유체통로(4a)나 혹은 (4b)를 폐쇄하게 된다. 따라서 유체유입공(2)를 통해 그 케이싱(3)의 수용실(4)의 내부로 유입되는 물은 개폐볼(8)의 개폐에 다라서 유체통로(4a)나 혹은 유체통로(4b)를 통해 유출된다.With this configuration, when the driving wheel 7 due to the motor driving (not shown) is driven, the driving force at this time is applied to the washing water which has already flowed into the interior of the storage chamber 4 through the fluid inlet hole 2. Thus, the washing water is transferred in an arbitrary direction with the driving pressure. At this time, the fluid pressure is applied to the opening and closing ball 8, and the opening and closing ball 8 closes the fluid passage 4a or 4b depending on the direction in which the fluid pressure is applied. Accordingly, the water flowing into the interior of the housing chamber 4 of the casing 3 through the fluid inlet hole 2 may open or close the fluid passage 4a or the fluid passage 4b according to the opening and closing of the opening / closing ball 8. Spills through.

즉, 유체통로(4a)측과 미도시한 배수관이 접속되어 있다고 하면, 개폐볼(8)이 유체통로(4b)를 폐쇄하고 있는 동안 세탁용수는 유체통로(4a)를 통해 외부로 배수되고, 반면에 개페볼(8)이 유체통로(4a)를 폐쇄하면 세탁용수는 유체통로(4b)측으로 접속된 샤워호스(미도시)를 통해 다시 헹굼용으로 공급되어지게 되는 것이다.That is, if the fluid passage 4a side and the drain pipe not shown are connected, the washing water is drained to the outside through the fluid passage 4a while the opening / closing ball 8 is closing the fluid passage 4b. On the other hand, when the dog ball 8 closes the fluid passage 4a, the washing water is supplied for rinsing again through a shower hose (not shown) connected to the fluid passage 4b.

이러한 투웨이펌프에 있어서, 유체통로들(4a, 4b)의 변환용 개폐볼(8)은 제2도 표시와 같이, 전체가 강성체(鋼性體)로 이루어져 있다. 이 때문에 구동휀(7)에 의한 수압작용으로 유동되는 개폐볼(8)은 덮개판(2)와 케이싱(3)의 내벽부위와 접촉시 마찰음을 발생되게 한다. 즉, 개폐볼(8)은 그 케이싱(3)과 덮개판(2)의 내벽부위와 심하게 부딪치면서 이동되므로, 세탁기의 외부로는 그 개폐볼(8)의 이동시마다 심한 마차음이 전달되어 사용자들로 하여금 그다지 좋지 않은 인상을 갖게 함이 현실정이다.In such a two-way pump, the opening and closing ball 8 for converting the fluid passages 4a and 4b is made of a rigid body as shown in FIG. For this reason, the opening / closing ball 8 which flows by the hydraulic action by the drive wheel 7 causes friction sound at the time of contact with the inner wall part of the cover plate 2 and the casing 3. That is, since the opening and closing ball 8 is moved while colliding with the inner wall of the casing 3 and the cover plate 2 severely, the outside of the washing machine is delivered with a serious carriage sound every time the opening and closing ball 8 is moved. It is a reality that makes them feel very bad.

따라서 본 고안의 목적은 상기 결점들을 해소하고, 개폐볼의 내부는 금속 물질을 이루게 형성하되 그 이상과 맞닿게되는 외 표면부위는 부드러운 탄성물질로 형성한 것에 의해, 볼의 이동시 마찰에 의한 소음발생이 전연 없도록 한 세탁기의 투웨이펌프용 개페볼을 제공하는 데에 있다.Therefore, the object of the present invention is to solve the above-mentioned defects, the inside of the opening and closing ball is formed of a metal material, but the outer surface portion which is in contact with the above is formed of a soft elastic material, the noise generated by the friction when moving the ball It is to provide a dog ball for a two-way pump of a washing machine without this leading edge.

상기 목적을 달성하게 위한 본 고안에 특징은, 저수조로 부터 배출되는 세탁용수를 배수하거나 혹은 헹굼용수로 순환되게하는 적어도 2개의 유체통로들을 갖는 케이싱과, 그 케이싱의 내부에 회전가능하게 위치되어 유체통로들을 선택적으로 개폐시킴에 제공되는 세탁용수의 수압이 작용되게 한 구동휀을 갖는 세탁기용 투웨이펌프에 있어서, 상기 케이싱내의 유체통로 사이에서 이동 가능하게 위치되어 구동휀에 의한 수압작용시 유체통로와의 마찰음발생이 없이 유체통로를 개페하는 구형상의 금속물질과, 그 금속물질의 전 표면을 감싸는 형태로서 소정의 두께를 이루며 일체로 형성된 탄성물질을 포함하는 세탁기의 투웨이펌프용 개폐볼에 있다.A feature of the present invention for achieving the above object is a casing having at least two fluid passages for draining the washing water discharged from the reservoir or allowing it to be circulated to the rinsing water, and the fluid passage being rotatably positioned inside the casing. A two-way pump for a washing machine having a driving fan for allowing hydraulic pressure of washing water provided to selectively open and close the valves, the two-way pump being positioned so as to be movable between the fluid passages in the casing and being connected to the fluid passage during the hydraulic operation by the driving fan.

이하, 첨부된 도면을 참조하여 본 고안에 다른 투웨이펌프용 개폐볼의 보다 바람직한 실시예를 상세하게 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail a more preferred embodiment of the opening and closing ball for another two-way pump in the present invention.

제3도는 본 고안에 의한 투웨이펌프용 개폐볼의 단면도를 나타낸 것이다.Figure 3 shows a cross-sectional view of the opening and closing ball for two-way pump according to the present invention.

도면표시와 같이 개폐용볼(10)은 내부에 위치한 구형상(球形狀)의 금속물질(12)와, 그 금속물질(12)를 감싸는 형태로서 수정의 두께(t)를 이루며 일체로 형성된 탄성물질(14)로 구성되어 있다.As shown in the drawing, the opening and closing ball 10 is a spherical metal material 12 located therein, and an elastic material formed integrally in a shape that encloses the metal material 12 and forms a thickness t of crystals. It consists of (14).

상기에서 개폐용볼(10)의 전체를 탄성물질(14)로 형성하지 않고, 일부는 금속물질(12)로 형성한 것은, 개폐용볼(10)의 중력(重力)를 유지하기 위해서이다.In the above, the entire opening and closing ball 10 is not formed of the elastic material 14, and part of the opening and closing ball 10 is formed of the metal material 12 to maintain gravity of the opening and closing ball 10.

상기 탄성물질(14)는 소음발생이 적은 고무로 함이 바람직하다.The elastic material 14 is preferably made of rubber with less noise.

이상과 같은 구성을 갖는 본 고안의 작용효과를 다시 제1도 및 제3를 참조하여 상세하게 설명한다. 제1도 표시와 같이, 구동휀(7)로 부터 유도되는 압력으로 인해 볼(10)이 유동하게 되면, 이 볼(10)은 종래와 같이 유체통로를(4a, 4b)를 선택적으로 개폐되게 하지만, 개폐용볼(10)의 이동시 덮개판(2)과 케이싱(3)의 내벽과 부딪치게 되더라도 그 표면에 설치한 쿠션력을 갖는 탄성물질(14)에 의하여 소음발생이 되는 일은 전연 없이 부드럽게 작용하면서 유체통로들(4a, 4b)를 개폐하게 된다.Effects of the present invention having the above configuration will be described in detail with reference to FIGS. 1 and 3 again. As shown in FIG. 1, when the ball 10 flows due to the pressure induced from the driving wheel 7, the ball 10 is made to selectively open and close the fluid passages 4a and 4b as in the prior art. However, even when the opening and closing the ball 10 is bumped into the inner wall of the cover plate (2) and the casing (3) while the noise generated by the elastic material 14 having a cushioning force installed on the surface smoothly without leading edge The fluid passages 4a and 4b are opened and closed.

이상과 같이 본 고안에 의하면 내부는 금속물질로된 강성체로 형성함과 아울로 그 강성체의 외 표면으로는 소정의 두께를 갖는 탄성물질로서 일체로 형성한 것에 의해, 유동시 케이싱의 내벽과 부딪치게 되더다로 마찰소음이 전연없게한 효과를 갖게 한 것이다.As described above, according to the present invention, the inside is formed of a rigid body made of a metal material, and the outer surface of the rigid body is formed integrally as an elastic material having a predetermined thickness so as to hit the inner wall of the casing during flow. In addition, friction noise had the effect of eliminating the leading edge.

또한, 내부에 설치한 금속물질로 인해 기존 강구(鋼球)와 같은 하중을 갖게 하는 효과를 갖게 한 것이다.In addition, due to the metal material installed inside it has the effect of having the same load as the existing steel ball (鋼球).
