Hereinafter, an integrated drum shake device for a drum washing machine according to an embodiment of the present invention will be described in detail. Figure 4 is a block diagram of a drum fixing device of the present invention. Figure 5 is a conventional forced threaded drum fixing part.

도 4에 도시된 바와 같이, 본 고안의 일실시예에 따른 드럼세탁기용 일체형 드럼흔들림 방지장치는 고정용볼트(B)와 드럼지지구(100)로 구성된 드럼세탁기용 일체형 드럼흔들림 방지장치에 관한 것이다.
As shown in Figure 4, the integrated drum shake prevention device for a drum washing machine according to an embodiment of the present invention relates to an integrated drum shake prevention device for a drum washing machine consisting of a fixing bolt (B) and the drum support (100). will be.

도 4에 도시된 바와 같이, 본 고안의 일실시예에 따른 드럼세탁기용 일체형 드럼흔들림 방지장치에 있어서, 드럼지지구(100)는 중공의 드럼지지편(10)과 확장편(20)으로 구성된다. 드럼지지편(10)은 상단이 세탁기 드럼 하부를 지지하고 중심에 중공부(中空剖)가 구비되며 원통형상이다. 확장편(20)은 드럼지지편(10) 하부에 위치하며 드럼지지편(10)보다 큰 직경으로 확장형성되고, 드럼지지편(10)과 확장편(20)이 플라스틱 재질로 일체로 형성되는 것이 특징이다.
As shown in Figure 4, in the integrated drum shake prevention device for a drum washing machine according to an embodiment of the present invention, the drum support 100 is composed of a hollow drum support piece 10 and the expansion piece 20 do. The drum support piece 10 has an upper end supporting the lower part of the washing machine drum, and a hollow part is provided at the center thereof and has a cylindrical shape. The expansion piece 20 is located below the drum support piece 10 and is expanded to a larger diameter than the drum support piece 10, and the drum support piece 10 and the expansion piece 20 are integrally formed of a plastic material. Is characteristic.

도 4에 도시된 바와 같이, 본 고안의 일실시예에 따른 드럼세탁기용 일체형 드럼흔들림 방지장치에 있어서, 드럼지지편(10)의 내면으로부터 중공부(中空剖)의 향하여 내측으로 돌출된 걸림날개(30)가 더 형성되는 것이 바람직하다. 걸림날개(30)는 2~4 조각으로 구성되고 하나의 원을 그리면서 서로 이격되게 구비되는 것이 바람직하다.
As shown in Figure 4, in the integrated drum shake prevention device for a drum washing machine according to an embodiment of the present invention, the locking blade protruding inward toward the hollow portion from the inner surface of the drum support piece (10) It is preferable that 30 is further formed. Hanging wing 30 is preferably composed of 2 to 4 pieces and is spaced apart from each other while drawing one circle.

본 고안의 일실시예에 따른 드럼세탁기용 일체형 드럼흔들림 방지장치에 있어서, 드럼지지구(100)가 플라스틱 사출로 제조되는 것이 바람직하다. 드럼지지구(100)는 폴리에틸렌(polyethylene, PE)와 폴리프로필렌(polypropylene, PP) 혼합체에 EPDM rubber(ethylene propylene diene Monomer rubber)를 더 함유되어 구성되는 것이 바랍직하다.
In the integrated drum shake prevention device for a drum washing machine according to an embodiment of the present invention, it is preferable that the drum support 100 is manufactured by plastic injection. Drum support 100 is preferably composed of a polyethylene (polyethylene, PE) and polypropylene (polypropylene, PP) mixture further contains EPDM rubber (ethylene propylene diene Monomer rubber).

본 고안의 일실시예에 따른 드럼세탁기용 일체형 드럼흔들림 방지장치에 있어서, 드럼지지구(100)는 100 중량%에 3~10 중량%의 EPDM rubber(ethylene propylene diene Monomer rubber)가 함유하는 것이 바람직하다. EPDM rubber가 3 중량% 미만의 경우 너무 경도가 높아 걸림날개(30)의 파손이 발생하거나 충격흡수효과가 떨어지는 문제가 있다. EPDM rubber가 10 중량% 초과의 경우 너무 경도가 낮고 소프트하여 드럼 지지력이 약하지고 원가가 상승하는 문제가 있다. 따라서, EPDM rubber는 3~10 중량%가 적당함을 시제품 테스트 결과 알 수 있었다.
In the integrated drum shake prevention device for a drum washing machine according to an embodiment of the present invention, the drum support 100 preferably contains 3 to 10% by weight of EPDM rubber (ethylene propylene diene monomer rubber) in 100% by weight. Do. If the EPDM rubber is less than 3% by weight, the hardness is too high, there is a problem that the breakage of the wing 30 occurs or the impact absorption effect is lowered. If the EPDM rubber is more than 10% by weight, the hardness is too low and soft, so there is a problem of weak drum support and increased cost. Therefore, it was found that EPDM rubber was suitable for 3 ~ 10% by weight.

이하에서 본 고안의 작용에 대하여 좀더 살펴본다. 걸림날개(30)는 볼트 조립후 볼트 빠짐 방지역활을 하며, 고정용볼트(B) 조립시 강제 압입 방식으로 조립되는데 본 고안의 경우 작은 힘으로도 조립이 가능하며 파손 방지 형상으로 파손 원천적으로 방지되는 효과가 있음을 알 수 있었다.
Hereinafter, look at the operation of the present invention more. The locking wing 30 serves to prevent the bolt from falling after assembling the bolt, and is assembled by a forced press method when assembling the fixing bolt (B). In the case of the present design, it can be assembled with a small force. It was found that there is an effect.

종래 기술의 제품은 드럼고정부와 충격 흡수용 고무를 조립후 고정용 볼트를 돌려 조립하여 강제적으로 드럼 고정부에 나사산을 강제적으로 생성시켜 조립하는 타입으로 제품 생산시 조립 시간이 증가하여 작업성이 떨어진다. 또한, 분리형으로 시간당 생산량 증대에 어려움이 있다.
The prior art product is a type in which the drum fixing part and the shock absorbing rubber are assembled and then assembled by turning the fixing bolt to forcibly create a screw thread in the drum fixing part. Falls. In addition, there is a difficulty in increasing the output per hour as a separate type.

하지만, 본 출원인 의해 사용되는 본 고안은 월 사용량 약 100만개 정도 인데, 본 고안은 종래의 드럼고정부와 충격흡수용고무를 일체형으로 구성하였고, PP와 PE 혼합체에 EPDM 고무를 함유한 복합 원재료를 개발하여 충격흡수용고무의 경도값과 거의 유사한 물성의 일체형 제품을 구현하였다. 또한, 볼트를 조립시 강제로 돌려서 나사산을 생성하는 방식이 아닌 고정용볼트 손쉽게 조립할 수 있으면서도 빠지지 않는 방법으로 개선하여 생산성을 향상시켰다. 종래에는 도 5와 같이 드럼고정부에 볼트를 강제로 조립하면서 돌출부를 깍아 나사산을 강제로 형성시키는 방법을 사용하였다.
However, the present invention used by the applicant is about 1 million monthly usage, the present invention is composed of a conventional drum fixing part and the shock-absorbing rubber in one piece, the composite raw material containing EPDM rubber in the PP and PE mixture This product was developed to realize an integrated product with physical properties almost similar to the hardness of shock absorbing rubber. In addition, instead of forcibly turning the bolt when assembling to create a thread, the fixing bolt can be easily assembled but not removed, thereby improving productivity. In the related art, a method of forcibly forming a screw by forcibly cutting a protrusion while assembling a bolt to a drum fixing part as shown in FIG. 5 is used.

본 고안은 상기에서 언급한 바람직한 실시예와 관련하여 설명됐지만, 본 고안의 범위가 이러한 실시예에 한정되는 것은 아니며, 본 고안의 범위는 이하의 실용신안등록청구범위에 의하여 정하여지는 것으로 본 고안과 균등 범위에 속하는 다양한 수정 및 변형을 포함할 것이다.Although the present invention has been described with reference to the above-mentioned preferred embodiments, the scope of the present invention is not limited to these embodiments, the scope of the present invention is defined by the following utility model registration claims to the present invention and It will include various modifications and variations that fall within the scope of equivalents.

아래의 실용신안등록청구범위에 기재된 도면부호는 단순히 고안의 이해를 보조하기 위한 것으로 권리범위의 해석에 영향을 미치지 아니함을 밝히며 기재된 도면부호에 의해 권리범위가 좁게 해석되어서는 안될 것이다.The reference numerals described in the utility model registration claims below are merely to aid the understanding of the design and do not affect the interpretation of the scope of rights, and the scope of rights shall not be construed narrowly by the reference numerals described.
