본 고안은 2조식 세탁기의 세탁축 결합구조에 관한 것으로 특히 세탁축의 기울어짐을 방지하기 위해 축하우징 지지점을 축하우징으로부터 멀리한 세탁조와 축하우징의 결합구조에 관한 것이다.The present invention relates to a laundry shaft coupling structure of a two-chamber washing machine, and more particularly, to a coupling structure of a laundry tank and a celebratory housing away from the celebratory housing to prevent the tilting of the laundry shaft.

종래 2조식 세탁기는 두개의 별도의 조가 구성된 하나의 튜브를 형성하여, 각 조의 내부 즉, 세탁조의 내부 하단부에는 펄세이터를, 그리고 탈수조의 내부에는 역시 측벽에 다수개의 통수구가 형성된 탈수통을 각각 회전가능하게 고정시키고, 이들 펄세이터 및 탈수통을 회전시키기 위한 전동모터 및 감속기어 등은 이들 튜브 및 외상이 고정되어지는 세탁기의 하부베이스에 직접 취부되어 축에 의하여 회전력을 전달토록 구성되어 있다. 따라서, 이러한 2조식 세탁기는 하나의 세탁기내에 각각 2개의 전동모터와 감속기어 및 이들을 구동시키는데 필요한 콘덴서 등과 같은 각종의 전장품들이 1조식 세탁기에 비하여 훨씬 많이 소요되며, 또한 전동모터와 감속기어 등 기계적 회전을 제공하는 부품들이 직접 하부베이스에 고정되어 있어 이들의 회전에 따라 발생되어지는 진동 및 소음 등이 바닥을 통하여 직접 외부로 전달되어지는 등의 단점이 있으나, 각 전동모터는 정해진 한정된 회전만을 수행하여도 전체 세탁이 이루어질 수 있으므르 비교적 가격이 저렴한 단순한 기계식의 스위치 및 타이머 등의 조합에 의하여 세탁기를 제어할 수 있으므로 수리 및 유지가 간단하고, 가격이 저렴하며 생산 공정이 비교적 단순하여 생산성이 높다는 장점이 있다.Conventional two-chamber washing machine forms a single tube consisting of two separate tanks, each of the dehydration canisters inside the tank, that is, a pulsator in the inner lower end of the washing tank, and a plurality of drains formed in the side wall in the dehydration tank, respectively The motor and the reduction gear for rotating the pulsator and the dehydrating container, which are rotatably fixed, are mounted directly on the lower base of the washing machine to which these tubes and the outer box are fixed, and are configured to transmit rotational force by the shaft. Therefore, the two-chamber washing machine takes much more electric equipment such as two electric motors and reduction gears and a capacitor required to drive them in one washing machine than the one-chamber washing machine, and also mechanical rotation such as electric motors and reduction gears. There are disadvantages such that the parts providing the direct is fixed to the lower base, such that the vibration and noise generated by their rotation is transmitted directly to the outside through the floor, but each electric motor performs only a limited rotation Since the whole washing can be done, the washing machine can be controlled by a combination of simple mechanical switches and timers, which are relatively inexpensive, so the repair and maintenance are simple, the price is low, the production process is relatively simple, and the productivity is high. There is this.
