Description

Direct type washing machine {DIRECT ERIVE 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.

Drives between a first position where the clutch member 31 supported in the state is lowered and a second position where the connecting rod 61 is further moved from the first position toward the drain motor 61 to open the drain valve 57. It is configured to do so.

By this configuration, the washing water flow forming member rotating shaft 23 and the spin basket rotating shaft 17 are coupled to each other via a pair of bearings, and the upper region of the spin basket rotating shaft 17 is coupled to the upper bearing housing 63. . The lower bearing housing 67 is coupled to the bottom surface of the upper bearing housing 63, and a combination thereof is fixedly coupled to the bottom surface of the tub 13.

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 rotates so that the inclined surface 42d is spaced apart from the clutch member 31 about the rotation shaft 45, and at the same time, the first clutch lift lever member 41 The second clutch lifting lever member 43 which is tooth-coupled with the member 41 is rotated about the pivot shaft 47.

Accordingly, the clutch member 31 which is in contact with each of the inclined surfaces 42d and 44d 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 lift lever members 41 and 43 which are tooth-coupled to each other rotate in a direction in which the corresponding operation section 42c approaches the clutch member 31 by the elastic force of the lever spring 48. Done. When the inclined surfaces of the respective working sections 42c and 44c come into contact with the inclined ribs 32c of the clutch member 31, the inclined ribs 32c move the inclined surfaces 42d and 44d of the corresponding working sections 42c and 44c. As a result, the inner tooth portion is separated from the outer tooth portion of the serration bushing 27. At this time, the projecting portion 33 formed on the upper surface of the clutch member 31 is accommodated in the recessed portion 36 formed on the bottom surface of the fixing bracket 35, whereby the clutch member 31 is in a rotational restraint state. At this time, 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 carried out, when the power is applied to the drain motor 59, the first and second clutch lift lever members 41 and 43 which are tooth-coupled to each other at the first position have a corresponding working section including the clutch member 31. The clutch member 31 is lowered along the axial direction by the self-weight and the elastic force of the spring member 37 to be engaged with the serration bushing 27.

When the drain motor 59 is continuously rotated and the connecting rod 61 is moved to the second position, the drain valve 57 is opened, and the first and second clutch lift lever members 41 and 43 are formed in the respective operating sections. 42c and 44c are further spaced apart from the clutch member 31, and 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 and dehydrated. Will perform the action.
