Description

드럼세탁기의 드럼과 스파이더의 결합구조{Structure for engaging spider to drum of drum type washer}Structure for engaging spider to drum of drum type washer}

본 발명은 드럼세탁기에 관한 것으로서, 특히 드럼의 구동을 위한 구동축이 고정되는 스파이더를 드럼의 후벽부에 고정되게 결합하기 위한 결합구조를 개선하여 고속 회전시에도 스파이더와 드럼 간의 고정상태가 안정되게 유지될 수 있도록 한 드럼세탁기의 드럼과 스파이더의 결합구조에 관한 것이다.The present invention relates to a drum washing machine, and in particular, to improve the coupling structure for fixing the spider fixed to the rear wall of the drum fixed drive shaft for driving the drum to maintain a stable state between the spider and the drum even at high speed rotation And a coupling structure of a drum and a spider of a drum washing machine.

일반적으로 드럼세탁기는 세제와 세탁수 및 세탁물이 드럼 내에 투입된 상태에서 구동부의 구동력을 전달받아 회전하는 드럼과 세탁물의 마찰력을 이용하여 세탁이 이루어지도록 한 장치로서, 세탁물의 손상이 적고, 세탁물이 잘 엉키지 않으며, 두드리고 비벼 빠는 세탁효과를 낼 수 있도록 한 것이다.In general, a drum washing machine is a device in which washing is performed by using a friction force of a rotating drum and laundry by receiving a driving force of a driving unit while detergent, washing water, and laundry are put in a drum. It does not get tangled, and it is designed to produce a laundry effect by tapping and rubbing.

도 1은 종래 일반적인 드럼세탁기의 구조를 개략적으로 나타낸 도면이고, 도 2는 종래의 드럼세탁기에 적용되는 드럼과 스파이더 간의 결합구조를 나타낸 것으로, 도 1과 도 2를 참조하여 종래의 일반적인 드럼세탁기의 구조 및 이에 채용되는 드럼과 스파이더의 결합구조에 대해 설명하면 다음과 같다.1 is a view schematically showing a structure of a conventional drum washing machine, and FIG. 2 is a view illustrating a coupling structure between a drum and a spider applied to a conventional drum washing machine, and referring to FIGS. 1 and 2 of a conventional drum washing machine. The structure and the coupling structure of the drum and the spider employed therein will be described as follows.

아웃케이스(100) 내측에는 원통형의 터브(10; tub)가 눕혀진 상태 즉, 터브(10)의 축방향과 세탁기가 설치되는 설치공간의 바닥면(이하 세탁기의 설치면이라함)이 평행하도록 설치되고, 상기 터브(10)의 내측에는 원통형의 드럼(20)이 드럼축(40)을 통해 구동모터(30)의 구동력을 전달받아 회전 가능하도록 상기 터브(10)와 동축으로 설치된다.In the outer case 100, a cylindrical tub 10 is laid down, that is, the axial direction of the tub 10 and the bottom surface of the installation space in which the washing machine is installed (hereinafter referred to as the installation surface of the washing machine) are parallel. A tubular drum 20 is installed coaxially with the tub 10 so as to be rotatable by receiving a driving force of the driving motor 30 through the drum shaft 40.

그리고, 상기 드럼(20) 후벽부에는 중앙에 상기 드럼축(40)의 끝단부가 고정되는 스파이더(50)가 고정되게 결합된다.Then, the spider 50 is fixed to the rear wall portion of the drum 20, the end portion of the drum shaft 40 is fixed to the center.

상기 스파이더(50)는 전술한 것과 같이 드럼축(40)의 일단을 결합시키는 역할과 함께 드럼(20) 후벽부의 강도를 보강하는 역할을 한다.The spider 50 serves to couple one end of the drum shaft 40 as described above, and serves to reinforce the strength of the rear wall of the drum 20.

한편, 도 2에 도시된 바와 같이 종래의 드럼세탁기는 상기 스파이더(50)의 세 끝단에 형성된 체결공(51)과 드럼(20) 후단부의 외주연부에 후방으로 연장된 연장부(21)에 형성된 체결공(22)들을 상호 정렬시킨 다음, 이들 체결공(51, 22)들을 통해 스크류(55)를 삽입함으로써 스파이더(50)를 드럼(20)의 후벽부에 고정시킨다.Meanwhile, as shown in FIG. 2, the conventional drum washing machine is formed in the fastening hole 51 formed at the three ends of the spider 50 and the extension part 21 extending rearward at the outer periphery of the rear end of the drum 20. After the fastening holes 22 are aligned with each other, the spider 50 is fixed to the rear wall of the drum 20 by inserting the screw 55 through the fastening holes 51 and 22.

그러나, 상기와 같은 종래의 드럼세탁기의 드럼과 스파이더 간의 결합구조는 탈수행정시 드럼 속도가 점차 고속화되어 가고 있는 추세에서 충분한 지지강도를 보장하지 못하는 문제가 있다.However, the coupling structure between the drum and the spider of the conventional drum washing machine as described above, there is a problem that does not ensure sufficient support strength in the trend that the drum speed is gradually increased during dehydration administration.

좀 더 구체적으로 설명하면, 전술한 바와 같이 종래에는 스파이더의 각 끝단부에 하나의 체결공만이 형성되고, 이 체결공을 통해 하나의 스크류가 체결되어 고정되므로, 드럼축(40)의 회전에 의한 스파이더(50)의 회전시 회전력은 드럼(20)과 스파이더(50) 간의 각 결합부, 즉 각 스크류(55)를 통해서 드럼(20)에 전달된다.More specifically, as described above, in the related art, only one fastening hole is formed at each end of the spider, and one screw is fastened and fixed through the fastening hole, so that the rotation of the drum shaft 40 is prevented. The rotational force when the spider 50 rotates is transmitted to the drum 20 through each coupling portion, that is, each screw 55, between the drum 20 and the spider 50.

따라서, 상기 스파이더(50) 및 드럼(20)이 회전할 때에는 상기 각각의 스크류(55)에 부하가 집중되는 현상이 발생하는데, 세탁 행정과 같은 저속 회전 상태에서는 각각의 스크류(55)가 이러한 하중을 충분히 견딜수 있으나, 16000rpm 등의 고속 회전수로 탈수 행정을 수행할 경우에는 스크류(55)가 이러한 원심력에 의한 하중을 견디지 못해 부러지거나 스크류(55)가 관통하는 드럼(20)의 체결공(22) 주변부위가 파손되는 등의 문제가 발생하게 된다.Therefore, when the spider 50 and the drum 20 rotate, a phenomenon occurs in which the load is concentrated on the respective screws 55. In the low-speed rotation state such as the washing stroke, each screw 55 carries such a load. Although it can withstand enough, when performing a dehydration stroke at a high speed, such as 16000 rpm, the screw 55 is unable to withstand the load by the centrifugal force or is broken or the fastening hole 22 of the drum 20 through which the screw 55 passes. Problems such as damage to the peripheral portion will occur.

이에 본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로, 회전시 드럼과 스파이더의 결합부위에 가해지는 하중을 적절히 분산시켜 고속 회전시에도 안정적인 고정 상태를 유지할 수 있도록 한 드럼세탁기의 드럼과 스파이더의 결합구조를 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems, the drum and spider of the drum washing machine to maintain a stable fixed state even at high speed by properly distributing the load applied to the coupling portion of the drum and the spider during rotation The purpose is to provide a coupling structure of.
