본 고안은 세탁기 및 탈수기의 제동장치에 관한 것으로 특히 커플링과 브레이크슈의 마찰면에 외선형 돌기부와 요홈부를 형성하여 가동중 필요에 의해 고속회전하는 탈수통이 단시간내에 재동될수 있도록함과 제동시 탈수통의 불균형 원심력에 따른 잡음 및 진동이 발생되지 않도록 된 세탁기 및 탈수기의 제동장치에 관한 것이다.The present invention relates to a braking device for a washing machine and a dehydrator, and in particular, an external protrusion and a recess are formed on the friction surface of the coupling and the brake shoe so that the dewatering container rotating at high speed as needed during operation can be restarted within a short time. The present invention relates to a brake of a washing machine and a dehydrator, in which noise and vibration are not generated due to an unbalanced centrifugal force of a dehydration container.

종래의 경우 탈수하고자하는 세탁물을 세탁기의 탈수통 혹은 탈수기의 탈수통에 장입한후, 소정의 탈수작업이 완료되면 사용자가 탈수통 뚜껑을 개방함으로서 구동모터의 구동축과 탈수통의 탈수통축간에 장착된 커플링부에 소정의 브레이크슈우가 부설된 아암이 탈수통뚜껑 개방에 따라 작동와이어에 작용되어 커플링의 하단면에 브레이크슈우가 밀착되면서 마찰력에 의해 제동되었으나, 그 제동력에 있어서는 장시간의 제동시간이 요구되었고, 또한, 탈수통에 장입되는 세탁물이 많을 경우에는 더욱 제동시간이 연장되는 결함이 발생됨에 따라 최근에는 도면 제 5 도에 도시된 바와같이 커플링(90)과 브레이크슈우(11)의 마찰에 의해 제동될 수 있도록 축 연결장치인 커플링 (9)의 하단면에 블록하에 원추형 마찰면(90a)이 형성되고, 브레이크슈우(11)의 상면이 오목하게 원추형 마찰면(11a)이 형성되어 있는 원추형 제동마찰면을 갖는 제동장치구조를 개발사용하고 있으나 이는 마찰제동면으로 되어 있으므로 회전제동력에 있어 그 한계가 있으며 또한 제동시 탈수통(8)이 회전되면서 불균형분포된 세탁물에 의해 불균형 원심력이 야기되어 소음 및 심한 진동이 발생되는등 여러 결점이 있었다.In the conventional case, the laundry to be dewatered is loaded into the dehydrating container of the washing machine or the dehydrating container of the dehydrator, and when a predetermined dehydration operation is completed, the user opens the dehydration container lid to install it between the drive shaft of the drive motor and the dehydration container of the dehydration container. An arm with a predetermined brake shoe attached to the coupling part was applied to the actuation wire according to the opening of the dehydration lid, and the brake shoe was brought into close contact with the lower end of the coupling, and the brake shoe was braked by the frictional force. In addition, when there is a lot of laundry loaded into the dehydration container, a defect that extends the braking time occurs more recently. As shown in FIG. 5, the friction between the coupling 90 and the brake shoe 11 is shown. The conical friction surface 90a is formed under the block on the lower end surface of the coupling 9, which is an axial connection device, so that the brake shoe 11 can be braked by the brake shoe 11. Brake device structure having conical braking friction surface with concave friction surface 11a is concave in upper surface is developed, but it has a limitation in rotational braking force because it is a friction braking surface. Rotating) causes uneven centrifugal force due to unbalanced laundry, causing noise and severe vibration.

따라서 본 고안은 상기와 같은 종래의 결점을 해소시키기 위해 커플링의 볼록원추형 마찰면에 외선형돌기부를 형성하고 브레이크슈우의 오목원추형 마찰면에 외선형 요홈부를 형성하여 브레이크 장치로 제동되면서 외선형의 돌기부와 요홈부의 체결력으로 제동력을 증대시켜 고속회전하고 있는 탈수통이 단시간내에 제동될 수 있도록함과 제동시 발생되는 진동 및 소음을 방지할 수 있도록 안출된 것으로 첨부된 도면에 의하여 그 구성과 작용효과를 상세히 설명하면 다음과 같다.Therefore, in order to solve the above-mentioned drawbacks, the present invention forms an outer projection on the convex conical friction surface of the coupling and an outer groove on the concave conical friction surface of the brake shoe to brake with a brake device. The braking force is increased by the clamping force of the protrusion and the recess, so that the dehydrating tank rotating at high speed can be braked within a short time, and it is designed to prevent vibration and noise generated during braking. When described in detail as follows.

The brake shoe 11 which is fastened via 11b is separated from the cuff ring 9.

이때 체결된 돌기부(9b)와 요홈부(11b)는 수직으로 용이하게 분리될 수 있도록 된 구조이다.At this time, the fastening protrusion 9b and the recess 11b are structured to be easily separated vertically.

이 상태에서 사용자가 별도의 전기적 장치에 의한 스위치 (도시되지 않음)를 조작하여 가동시키게되면 세탁기 및 탈수기의 본체(1) 바닥면에 진동방지 고무스프링(6)을 통해 장착된 모터(7)의 구동으로 모터축(7a)과 탈수통(8)에 조립된 탈수통축(8a)이 커플링(9)을 통해 체결된 구조로 되어 있기 때문에 모터(7)구동에 의해 탈수통(8)이 회전하므로서 탈수과정을 거치게되며 계속적인 회전력에 의해 탈수가 완료된 다음 사용자가 세탁물을 빼내기 위해 탈수조뚜껑(3)을 개방하게 되면, 별도의 전기적인 장치에 의해 전원공급이 차단되면서 탈수조뚜껑(3) 후단부에 작동와이어 (5)를 통해 연결된 작동레버(4)가 아래로 내려오면서 작동와이어(5)는 느슨해지게되며, 이는 브레이크슈우(11)가 안착되면서 안내봉(12)을 따라 상하 이동될 수 있도록 본체(1)에 고정설치된 탈수조(2)의 하단부와 다수의 인장스프링(12)을 통해 탄력설치된 프레임(10)하단에 작동와이어(5)가 묶여져있기 때문에 탈수조뚜껑(3)을 닫았을때는 작동와이어(5)가 프레임(10)을 하향으로 당기게되어 다수의 인장스프링(12)을 당기고 있는 상태이면서 브레이크슈우(11)의 원추형 마찰면(11a)과 커플링 (9)의 원추형마찰면(9a)과는 이격되어 있는 상태로 탈수작용을 하는 과정에서 상기한 바와같이 탈수조뚜껑(3)을 개방하게되면 작동와이어(5)가 느슨해짐과 동시에 다수의 인장스프링(12) 복원력에 의해 브레이크슈우(11)가 안착된 프레임(10)은 안내봉(13)의 안내를 받으며 상향 이동되면서 인장스프링(12)의 복원력으로 브레이크슈우(11)의 원추형 마찰면(11a)과, 커플링(9)의 원추형 마찰면(9a)과의 밀착력으로 작용되며 이는 탈수동작에 따른 탈수통(8)의 제동력으로 되는 것이다.In this state, when the user operates and operates a switch (not shown) by a separate electrical device, the motor 7 mounted on the bottom surface of the main body 1 of the washing machine and the dehydrator through the anti-vibration rubber spring 6 Since the dehydration cylinder shaft 8a assembled to the motor shaft 7a and the dehydration cylinder 8 by the drive is fastened through the coupling 9, the dehydration cylinder 8 rotates by driving the motor 7. As it goes through the dehydration process and after the dehydration is completed by the continuous rotation force, the user opens the dehydration tank lid (3) to remove the laundry, the power supply is cut off by a separate electrical device, the dehydration tank lid (3) As the operation lever 4 connected to the rear end through the operation wire 5 is lowered, the operation wire 5 is loosened, which moves up and down along the guide rod 12 as the brake shoe 11 is seated. Fixed to the body (1) Since the operation wire 5 is tied to the lower end of the dehydration tank 2 and the lower end of the frame 10 that is elastically installed through the plurality of tension springs 12, the operation wire 5 is closed when the dehydration tank lid 3 is closed. The frame 10 is pulled downward to draw a plurality of tension springs 12 while being spaced apart from the conical friction surface 11a of the brake shoe 11 and the conical friction surface 9a of the coupling 9. When the dehydration tank lid 3 is opened as described above in the process of dehydration, the brake shoe 11 is seated by the restoring force of the tension springs 12 and at the same time the working wire 5 is loosened. The frame 10 is moved upward while being guided by the guide rod 13 to the conical friction surface 11a of the brake shoe 11 and the conical friction surface of the coupling 9 by the restoring force of the tension spring 12. It acts as an adhesion force with 9a), which is a braking force of the dehydration container 8 according to the dehydration operation. Will be.

이때 프레임(10)에 안착된 브레이크슈우(11)의 상면에 오목하게 형성되어 있는 원추형마찰면(11a)에 외선형 요홈부(11b)가 형성됨과 이와 밀착체결되는 커플링(9)하면에 볼록하게 형성되어 있는 원추형마찰면(9a)에 외선형 돌기부(9b)가 형성되어 있어 원추형마찰면으로서의 제동작용은 물론 상호 조합 밀착상태가 돌기부(9b)와 요홈부(11b)에 의해 상호 체결되면서 쐐기형태로 작용됨에 따라 상호간에 작용되는 제동력은 더욱 증대되어 제동효과를 크게되는 것이다.At this time, the outer concave groove portion 11b is formed on the conical friction surface 11a formed concave on the upper surface of the brake shoe 11 seated on the frame 10, and convex on the lower surface of the coupling 9 which is tightly coupled thereto. The outer projections 9b are formed on the conical friction surface 9a which is formed so that the braking action as the conical friction surface as well as the mutually close contact state are mutually fastened by the projections 9b and the recesses 11b. As it acts in the form, the braking force applied to each other is further increased to increase the braking effect.

따라서 탈수하고자하는 세탁물의 양에 관계없이 제동시간을 단축시킬 수 있으며 또한 체결되면서 제동되기 때문에 제동시, 세탁물의 장입상태가 불균형하게 장입되었다 하더라도 탈수조(2)와 탈수통(8)과의 충돌과같은 결함을 해소시킴에 따라 소음 및 진동발생을 방지할 수 있는 것이다.Therefore, the braking time can be shortened regardless of the amount of laundry to be dehydrated, and the braking time can be reduced by tightening, so that the collision between the dehydration tank (2) and the dehydration tank (8), even if the loading state of the laundry is unbalanced, is prevented. By eliminating such defects, it is possible to prevent the occurrence of noise and vibration.

이상에서 본 바와같이 본 고안은 커플링(9)의 원추형마찰면(9a)에 외선형 돌기부(9b)를 형성하고 브레이크슈우(11)의 원추형마찰면(11a)에 외선형 요홈부(11b)를 형성하여 상기 돌기부(9b)및 요홈부(11b)를 형성하여 상기 돌기부(9b)및 요홈부(11b)의 체결에 따른 체결력으로 제동될 수 있게 하여 최대의 제동력을 지니게함은 물론 제동시 발생되는 소음 및 진동을 제거시킴으로서 안전한 탈수작업을 실시할 수 있도록 된 것이다.As described above, the present invention forms the outer projection 9b on the conical friction surface 9a of the coupling 9 and the outer groove 11b on the conical friction surface 11a of the brake shoe 11. To form the protrusions 9b and the recesses 11b so that the protrusions 9b and the recesses 11b can be braked by a fastening force according to the fastening of the protrusions 9b and the recesses 11b, and thus have a maximum braking force as well as occurrence during braking.
