[Field of design]

The present invention relates to a shaft assembly structure for fixing the rotating shaft of the dehydration tank in the dehydration tank in a two-chamber washing machine.

In particular, the present invention in the two tank type washing machine using a single motor in the power transmission structure by the belt between the pulley fixed to the lower end of the rotary shaft of the dehydration container and the rotating shaft of the electric motor in the dehydration shaft rotatably fixed to the vibration damping spring and dehydration shaft It relates to a shaft assembly structure to absorb the flow shock of the shaft due to the imbalance that can occur during dehydration by the combination of the bearing to make.

[Design background]

The washing machine which is widely used at present can be roughly divided into two types, one tank washing machine and two tank washing machine.

One tank washing machine can perform both washing and dehydration in a single reservoir, and for this purpose, the rotation of the pulsator, which is rotatably fixed to the reservoir, is fixed to the lower portion of the reservoir fixed by hanging inside the outer casing of the washing machine. Washing process can be carried out by the dehydration process, and also having a single dehydration tank (1) to form a plurality of water outlets on the side wall in the water tank separately from the water storage tank to dehydrate the laundry by the rotation It is configured to do this. These pulsator and dewatering tank (1) receives the rotational force of the electric motor and the electric motor fixed to the outer lower surface of the water storage tank and reduces the rotational force of the high speed small torque of the electric motor to the rotational force of the low speed large torque. It is connected to the main shaft so that only the pulsator in the washing process and only the dehydration tank (1) in the dehydration process according to the rotation of the electric motor is configured to enable complete washing.

One tank washing machine of such a configuration is configured to wash and dewater in one water tank, which greatly reduces the volume of the entire washing machine, and the electric motor and the reduction gear are suspended at the lower end of the water tank so that vibration and noise are greatly increased. Although it has the advantage of being reduced, a variety of rotational forces required for the whole washing such as the forward rotation, the stop, the reverse rotation and the rotation for a certain time in one direction during dehydration by a single electric motor and the reduction gear connected thereto In order to control the rotation of the electric motor in various ways, it is not possible to perform sufficient washing by simple switches and timers. Therefore, a circuit for controlling a series of pre-programmed operations such as a microprocessor is required. , The price of the product itself increases accordingly. , Also the production process, such as suspending the reservoir, etc. The entire electric motor and the reduction gear suspended inside the washing machine trauma productivity drops difficult.

In addition, the two-chamber washing machine forms a tube composed of two separate tanks, ie, a pulsator inside each tank, that is, an inner lower end of the washing tank, and a plurality of water holes on the side wall of the dewatering tank 1 are also provided. The dehydrator (2) formed is rotatably fixed, respectively, the pulsator and the electric motor and the reduction gear for rotating the dehydrator (2) are mounted directly on the lower base of the washing machine to which these tubes and trauma are fixed. It is configured to transmit rotational force by the shaft. Therefore, this two-screw washing machine takes much more electric equipment such as two electric motors and reduction gears and a condenser required to drive them in one washing machine, and requires much more than l-type washing machines, 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, and the production process is relatively simple, the productivity is high. have.

Therefore, there is a need for a new washing machine having both the advantages of a conventional one-chamber washing machine and a two-chamber washing machine. Accordingly, the present inventors use one motor instead of two motors in the conventional two-chamber washing machine. , Developed a washing machine configured to rotate by rotating the rotating shaft of one motor by the pulleys (4) and the belt (10) fixed to the pulsator and the dehydrator (2), in a two-type washing machine of such a single motor The motor uses one electric motor to transmit the external power to the belt 10 so that the pulsator in the washing tank and the dehydrating tank 2 in the dehydrating tank 1 can be selectively rotated by the clutch, respectively. However, in the transmission mechanism by the belt 10, the belt 10 is transmitted to the pulley 4 fixed to the lower end of the rotary shaft of the dehydration container 2, so that power is transmitted. Due to the shaft itself is inclined toward the electric motor on the basis of the fixed point that is fixed to the lower end of the dehydration tank (1) significant vibration occurs due to the non-uniform rotation of the dehydration container (2). In the case of the conventional two-chamber washing machine, a separate electric motor connected to the shaft of the dehydration container 2 is fixed directly below the dehydration container 2 in order to provide a rotational force for rotating the dehydration container 2. Since the dehydration container (2) and the electric motor are located in a straight line, the shaft is not inclined. The electric motor itself has a cushion structure composed of a combination of the coil spring (7) and the anti-vibration rubber, and the lower part of the washing machine on which the electric motor is seated. Since it is attached to the base first and the electric motor is fixed to the upper end, a separate dustproof device is not necessary.

In this regard, the inventors of the dehydration shaft for rotating the dehydration container (2) of the dehydration container fixing shaft (5) fixed to the bottom portion of the dehydration container (2) and the pulley (4) fixed to one side end of the unwinding fixed shaft (3) A cylindrical shaft fixing rib (9) formed on the lower surface of the dewatering tank (1) in which the dewatering tank (2) is mounted, by separating the two shafts, and using the at least two sets of bearings (6). The spring line, which is rotatably fixed in the dehydration tube fixing shaft 5 and the decoupling shaft 3, is unevenly pitched so that the spring line that runs the pitch is interviewed on the side of the adjacent spring line, or is almost close to the interview. To solve the above problems and to complete the present invention by developing a shaft assembly structure to absorb the flow shock of the shaft due to the imbalance that can occur when dewatering by mechanically connecting by using a cylindrical spring (7) of the wound high tension.

It is to provide a shaft assembly structure to absorb the flow shock of the shaft due to the imbalance that may occur during dehydration by a combination of bearings to secure.
