Description

Direct Drive Washing Machine {DIRECT DRIVE WASHING MACHINE}

The present invention relates to a direct-type washing machine, and more particularly, it is possible to improve the washing effect of the fabric by enabling the formation of a variety of washing water, as well as to reduce the damage of the fabric and load of the electric motor. It relates to a direct type washing machine.

1 is a longitudinal sectional view of a conventional direct type washing machine. As illustrated, the direct type washing machine includes a casing 101 having an upwardly open tubular shape, a tub 103 that is suspended on the inside of the casing 101 to accommodate washing water therein, and a tub 103. It is coupled to a cylindrical spin basket (105) rotatably received in the interior of the spin basket 105, and coupled to the rotating shaft of the spin basket (105) coupled downwardly extending from the bottom region of the spin basket (105) to rotate and drive the spin basket (105). The motor 109 is provided.

In the inner bottom region of the spin basket 105, a washing water flow forming member 107, called a pulsator or edge data, is rotatably formed so as to form washing water flow.

By the way, in such a conventional direct-type washing machine, the washing water flow forming member 107 and the spin basket 105 are rotated integrally regardless of the kind and quantity of washing water, so that the amount of water and washing water When relatively small, the fabric is rotated in the same direction as the spin basket 105 during the rotation of the spin basket 105 has a problem that the washing of the fabric is insufficient. Accordingly, even when the amount is relatively small, it is not possible to reduce the number of washes, thereby increasing the amount of washing water and detergent used.

In addition, in the conventional direct-type washing machine, the inertia of the spin basket 105 is relatively inertial relative to a pulsator or agitator that is installed to be rotatable relative to the spin basket 105 to form a water stream. Inertia is designed to reversely rotate the large spin basket 105, thereby increasing the load of the electric motor 109 and hindering driving efficiency.

Accordingly, it is an object of the present invention to provide a direct washing machine that enables not only to improve the washing effect of the fabric by allowing the formation of various washing water flows, but also to reduce the damage of the fabric and the load of the electric motor.

The distal region of the drive lever 49 is connected to the connecting rod 61 disposed on the bottom surface of the tub 13 so as to be relatively movable, and connects the lever spring 48 to one side of the drive lever 49. Let's do it. The clutch member 31 is coupled to the spin basket rotary shaft 17, the stator 53 is coupled to the bottom surface of the lower bearing housing 67, and the serration bushing 27 is interposed on the laundry flow forming member rotary shaft 23. So that the rotor 55 is coupled.

When the coupling is completed, the tub 13 is accommodated in the casing 11 so as to be suspended and supported by the support rod 12, and the spin basket 15 is accommodated in the tub 13 so that the spin basket rotating shaft ( 17) to be integrally rotatable. When the washing water flow forming member 21 is accommodated in the spin basket 15 to fix the washing water flow forming member 21 to the washing water flow forming member rotating shaft 23, the coupling is completed.

Referring to the operation of the present direct type washing machine having such a device characteristics as follows.

When water is supplied, power is applied to the drain motor 59 so that the connecting rod 61 is moved to the first position. As a result, the first clutch lift lever member 41 connected to the connecting rod 61 is rotated such that the inclined surface 42d is spaced apart from the clutch member 31 about the rotation shaft 45.

When the first clutch lift lever member 41 rotates about the first pivot 45, the second arm 58 hinged through the first arm 52 and the hinge pin 71 may be a second one. The inclined surface 44c is rotated so as to be spaced apart from the inclined rib 32c about the rotation shaft 47.

Accordingly, the clutch member 31 which is in contact with each of the inclined surfaces 42c and 44c of the first and second clutch lift lever members 41 and 43 has a first outer tooth portion 19 of the spin basket rotary shaft 17. It descends along and engages with the serration bushing 27. At this time, when the rotor 55 is rotated at a low speed, the rotational force of the rotor 55 is transmitted to the spin basket rotation shaft 17 through the clutch member 31, and the spin basket 15 is the laundry flow forming member 21. By rotating together with the washing water to be quickly and evenly penetrated into the fabric.

In this state, when the rotational speed of the rotor 55 is increased, the washing water moves outward by centrifugal force, moves upward through the gap between the spin basket 15 and the tub 13, and descends to the center area and circulates. The so-called permeation washing is performed to accelerate the dissolution of the detergent and to carry out the washing operation through the cloth.

When the rotor 55 is rotated forward and backward at a relatively fast speed in the state in which the clutch member 31 is lowered, the laundry flow forming member 21 and the laundry flow forming member 21 integrally rotate and wash the laundry. So-called laundering will be performed.

On the other hand, when you want to wash using only the washing water flow forming member 21, the power supplied to the drain motor 59 is cut off. Then, the first and second clutch lifting lever members 41 and 43 which are hinged to each other via the hinge pins 71 have the inclined surfaces 42c and 44c by the elastic force of the lever springs 48. It will rotate in the direction approaching 31).

At this time, the upper guide portion 38a and the lower guide portion 38b support the vertical portion 72a and the horizontal portion 72b of the hinge pin 71 so as to be slidable, respectively, so that the hinge pins 71 move upward and downward. This prevents flow along.

When the inclined surfaces 42c and 44c come into contact with the inclined ribs 32c of the clutch member 31, the inclined ribs 32c move upward along the corresponding inclined surfaces 42c and 44c so that the inner teeth thereof are the serration bushings 27. It is in a state separated from the outer teeth of the. The projection 33 formed on the upper surface of the clutch member 31 is accommodated in the depression 36 formed on the bottom surface of the fixed bracket 35, whereby the clutch member 31 is in a rotational restraint state. In this state, when the rotor 55 is rotated forward and backward at a predetermined speed, the spin basket 15 performs the washing operation while only the washing water flow forming member 21 rotates forward and backward while the rotation is suppressed.

When dehydration is to be performed, when the power is applied to the drain motor 59, the inclined surfaces 42c and 44c are inclined at the first and second clutch lift lever members 41 and 43 which are tooth-coupled to each other at the first position. It rotates in the direction away from the rib 32c, and the clutch member 31 descends along the axial direction by the self-weight and the elastic force of the spring member 37 to be in engagement with the serration bushing 27.

When the drain motor 59 continues to rotate and the connecting rod 61 moves to the second position, the drain valve 57 is opened, and the first and second clutch lift lever members 41 and 43 have respective inclined surfaces clutched. In a state further spaced apart from the member 31, when the rotor 55 is rotated at a relatively high speed, the spin basket 15 and the washing water flow forming member 21 are integrally rotated to perform dehydration.

In the above-described and illustrated embodiments, the case in which the first and second clutch lift lever members are configured to be driven by the drain motor is explained by way of example, but separate driving means, for example, a separate electric motor. Alternatively, it may be configured to rotate with a solenoid or the like.

As described above, according to the present invention, the washing water flow forming member coupled to the inside of the spin basket so as to be relatively rotatable, and the spin basket rotating shaft and the washing water flow forming member rotating shaft are arranged concentrically to move up and down unevenness with respect to the direction of rotation.
