The present invention relates to a washing machine, and more particularly, to a complex drum washing machine employing a spiral winding stirrer configured to be suitable for a drum washing machine.

Conventional drum washing machine, when the drum rotates, the laundry hangs on the lifter formed on the inner wall of the drum and rises, and when the drum is pushed down by the protrusion of the water-soaked laundry and falls to the drum floor by repeated exaggeration falling to the drum floor. Washing proceeds under the influence of impact and pressure, but there is almost no problem of cloth damage or non-uniform washing, but the washing effect per unit time is low, so it is not possible to satisfy the desire of consumers to wash rapidly because washing is necessary only for a long time. There are disadvantages.

Accordingly, an object of the present invention is to add a pulsate type configuration to a conventional drum type washing machine in order to eliminate the above problems, and the object of the present invention is to provide a drum (17) wall surface. The stirrer 20 is rotatably installed, and the drive plate 12 capable of driving the stirrer 20 is connected to each other with the stirrer 20, and the drum rotary shaft 4 is piped to drive therein. The plate rotating shaft (3) is supported by two bearings (6) and is achieved by providing a combined drum washing machine having a stirrer drive motor (32) for driving the drive plate rotating shaft (3).

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of the drum washing machine of the present invention, the tub 1 is connected to the inside of the washing machine cabinet by a support spring as in the prior art, but the support spring is not shown in the drawing. In the center of the tub support (2) of the tub (1), the drive plate rotating shaft (3) and the drum rotating shaft (4) is located, the drum rotating shaft (4) is rotatable with respect to the tub support (2) by the bearing (5) Is supported.

Referring to FIG. 2, the drive plate rotating shaft 3 passes through the drum rotating shaft 4 and is rotatably supported by the metal bearing 6, and is sealed to prevent penetration of water or moisture by the seal 7. In the meantime, grooves 8 and 9 are formed at both sides of the drive plate rotation shaft 3 so that the ring 10 is inserted into the grooves 8 and 9 so that the drive plate rotation shaft 3 is in the axial direction. To prevent it from moving.

An agitator drive pulley 11 is fastened to one end of the drive plate rotating shaft 3, and an agitator drive plate 12 is fastened to the end of the drive plate rotating shaft 3 with a washer 14 and a nut 15 via a peace washer 13. It is.

The drum drive pulley 16 is fastened to one end other than the drum rotation shaft 4, and the drum support 18 of the drum 17 is coupled to the insert molding by the other end.

Referring again to FIG. 1, the vortex winding stirrer 20 is attached to the wall surface of the drum 17 up and down, and FIG. 3 shows the attachment state of the vortex winding stirrer 20 in detail.

Referring to FIG. 3, a separate bracket 21 is installed on the wall of the drum 17, and the stirrer shaft housing 22 is fixed to the wall of the drum 17 and the bracket 21 by bolts and nuts. In the stirrer shaft housing 22, the stirrer shaft 23 is rotatably supported by the metal bearing 24, and a ring 25 is fitted above and below the stirrer shaft 23, so that the stirrer shaft 23 is made of copper. To prevent. The stirrer 20 is fixed to the upper end of the stirrer shaft 23 by the screw 26.

Referring to FIG. 1, a stirrer drive plate 12 is shown in engagement with the stirrer 20, the connections of which are shown in FIG. 4 and FIG.

Referring to FIG. 4, a gear 19 is formed in the circumference of the stirrer drive plate 12. Also shown in this figure are two projections 37 provided at an angle of 90 degrees.

Referring to FIG. 5, the gears 27 are also formed at the circumference of the stirrer 20 so that the gears 19 of the stirrer drive plate 12 and the gears 27 of the stirrer 20 are engaged with each other. In addition, a protective wall 36 is installed at the edge of the stirrer 20 to prevent laundry from being inserted under the stirrer 20 during washing.

Referring back to FIG. 1, the stirrer drive pulley 11 connected to the end of the drive plate rotating shaft 3 is connected to the stirrer drive motor pulley 30 by a belt 31, and the stirrer drive motor pulley 30. ) Is connected to the stirrer drive motor 32 attached to the tub (1). Meanwhile, the drum drive pulley 16 fastened to the end of the drum rotation shaft 4 is connected to the motor pulley 33 by a belt 34, and the motor pulley 33 is a tub opposite the stirrer drive motor 32. It is connected to the drum drive motor 35 attached to (1).

Referring to the operation of the drum washing machine of the present invention configured as described above are as follows. When power is supplied to the washing machine and starts to operate, the drum driving motor 35 is operated, and the rotating shaft 4 rotates through the pulley 16 to rotate the drum 17. In addition, when the stirring mechanism driving motor 32 is operated, the driving plate rotating shaft 3 rotates the pulley 11, and accordingly, the driving plate 12 rotates and is engaged with the gear 19 formed around the driving plate 12. The gear 27 of the stirrer 20 is rotated, so that two opposite stirrers 20 are rotated.

Therefore, the complex drum washing machine according to the present invention is intended to rotate the drum 17 by driving the drum drive motor 35 like the conventional drum type washing machine, in order to carry out the laundry washing or the washing of the laundry with less contamination. When laundry inside is lifted and lifted by the lifter 37, the laundry is heavily contaminated, and when the laundry is highly polluted or rapid washing is required, the stirrer 20 is rotated by driving the stirrer driving motor 32 to form a pulsator type. I can wash it. In addition, when uniform and rapid washing is required, the two motors 32 and 35 are simultaneously driven to simultaneously rotate the drum 17 and the stirrer 20 to achieve the desired purpose.

Therefore, according to the present invention, the laundry can be washed without damaging delicate laundry, and the drum washing method and the pulsator washing method can be selected or used in parallel for washing the drum and the pulsator washing method. There is an effect that can all be taken.
