[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 prevents the eccentricity of the shaft 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 rotary shaft of the electric motor in a two-chamber washing machine using a single motor and at the same time vibrate due to the rotation of the eccentric shaft It relates to a shaft assembly structure formed by dividing the rotating shaft into an upper shaft and a lower shaft to prevent them and connecting them with at least three springs of high tension.

[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 one water tank, and for this purpose, a pulsator (3) rotatably fixed with respect to the water tank at the bottom of the water tank fixed to the inside of the outer shell of the washing machine. Washing process can be performed by the rotation of the water tank, and a plurality of water outlets are formed on the side wall of the water tank separately from the water tank, and has a dewatering tank 2 to dehydrate the laundry by the rotation thereof. It is configured to perform the dehydration process. These pulsator (3) and dehydration tank (2) receives the rotational force of the electric motor and the electric motor fixed to the outer lower surface of the water reservoir to reduce the rotational force of the high speed small torque of the electric motor to the rotational force of the low speed large torque Since it is connected to the main shaft of the reduction gear, it is configured to allow complete washing by rotating only the pulsator (3) in the washing process and only the dehydrating tank (2) in the dehydration process according to the rotation of the electric motor.

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, a simple switch and a timer cannot be used to perform sufficient washing. Therefore, a circuit for controlling a series of pre-programmed operations such as a microprocessor is required. As a result, the price of the product itself is increased. , 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 consisting of two separate tanks, pulsator (3) in the inner bottom of each tank, that is, the inner lower end of the washing tank (1) and also inside the dehydrating tank (2) on the side wall A plurality of water outlets are formed so that each of the dehydrating tanks 4 formed therein can be rotatably rotated, and the electric motors and reduction gears for rotating the pulsator 3 and the dehydrating barrel 4 are fixed to these tubes and traumas. Directly mounted on the lower base of the washing machine is configured to transmit the 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 capacitor required to drive them in one washing machine than the one-screw 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 repair and maintenance are simple, inexpensive, and the production process is relatively simple, resulting in high productivity. There is this.

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 belt and the pulleys (17) fixed to the pulsator (3) and the dehydrator (4), The motor uses a single electric motor to transfer the rotational force to the belt so that the pulsator 3 in the washing tank 1 and the dehydrating tank 4 in the dehydrating tank 2 can be selectively rotated by clutches, respectively. This is shown in FIG. However, in the transmission mechanism by the belt, the belt itself is transmitted to the pulley 17 fixed to the lower end of the rotation shaft of the dehydration tube 4, so that the shaft itself is dehydrated due to the tension of the belt. Since it is inclined toward the electric motor on the basis of the fixed point fixed to the lower end, considerable vibration occurs due to the non-uniform rotation of the dehydrator (4). In the case of the conventional two-chamber washing machine, a separate electric motor connected to the shaft of the dehydration container 4 is fixed directly below the dehydration container 4 to provide a rotational force for rotating the dehydration container 4. Since the dehydration tube (4) and the electric motor are in a straight line, the shaft is not inclined. The electric motor itself has a cushion structure (6) consisting of a combination of coil spring and anti-vibration rubber, and the lower part of the washing machine on which the electric motor is seated. Since it is mounted on the base first and the electric motor is fixed on the upper end, no separate dustproof device is needed.

The present inventors effectively fixed the two-type washing machine using a single motor to receive the rotational force from the electric motor by the pulley 17 so that vibration does not occur due to eccentricity of the dewatering shaft 5 due to the tension of the belt. The dehydration shaft 5 is divided into two axes of the upper shaft 11 and the lower shaft 12, and a spring fixing plate 13 is formed at the lower end of the upper shaft 11 and the upper end of the lower shaft 12, respectively. (1) and the lower shaft (12) of the celebration housing (15) surrounding at least three high-strength springs (14) and surrounding the dehydration shaft (5) divided into the upper shaft (11) and the lower shaft (12). A shaft assembly is formed by placing a bearing 16 at a contact portion between a lower end portion and a lower end portion of the lower shaft 12 so that the pulley 17 is connected to the lower end portion of the lower shaft 12 protruding from the celebration housing 15. Develop a structure to solve the above problems And it completed the present invention;
