Abstract

PURPOSE: To provide a fully automatic washing machine, by which mechanical force required for washing can be obtained, by putting materials to be washed on a shelf removably installed in the interior of a spinning basket, and passing the vertical circulating wafer jet generated by high-speed rotation of a pulsator through the materials to be washed. CONSTITUTION: A shelf 33 is arbitrarily removably installed in a spinning basket 21. In washing and rinsing processes, materials to be washed are fixed on the shelf 33. A pulsator 26 fitted to a washing shaft 23 is rotated by a driving motor 27. Thus, a pump blade 29 is rotated in a pump chamber 28 to generate pumping action. Water discharged from a discharge opening 32 by the pumping action passes through a water passage 30 and jetted from an opening part 31. The vertical circulating water at this time is passed while passing through the materials to be washed on the shelf 33. Accordingly, the stains on the materials to be washed can be removed evenly. Further, it is possible to prevent damage of materials to be washed due to the excessive mechanical force of the pulsator 26 and mutual entanglement of materials to be washed.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fully automatic washing machine which is used in general households, in which washing and rinsing of clothes are performed by a pulsator rotating at a low speed and dehydration is performed by rotating a dehydrating tank at a high speed.

[0002]

2. Description of the Related Art A conventional fully automatic washing machine has a structure as shown in FIG. That is, the main body 1, a water tank 3 supported by the suspension 2 in the main body 1, a dehydration tank 5 having a hollow dehydration shaft 4 on the top surface and a hollow bottom surface, and a water tank 3 supporting the dehydration shaft 4. It is composed of a bearing 6 provided on the bottom surface. 8 is a bearing 7 inside the dehydration shaft 4.
The washing shaft supported by the rotator drives the pulsator 9 inside the dehydration tub 5. Further, the washing shaft 8 is linked with the drive motor 10. 11 is a dehydration shaft 4 and a washing shaft 8
It is a clutch that disconnects with. Reference numeral 12 is a drain cock.

[0003]

In such a structure, the power of the drive motor 10 is transmitted to the pulsator 9 through the washing shaft 8 in the washing and rinsing steps, and the mechanical force is applied to the article to be washed. This mechanical force causes the items to be laundered in the water tank 5 to rub each other when they are moved by the pulsator 9 or the water flow, or to the wall surface of the dehydration tank 5 or the like. Has too much mechanical power to be damaged or shrink. Although the rotation speed of the pulsator 9 is reduced as a countermeasure against this, the mechanical force necessary for cleaning cannot be obtained, and there is a burden to reduce the rotation speed electrically.

The present invention is intended to solve the above problems,
We provide a fully automatic washing machine that puts the laundry on the shelf at the time of washing and causes the pump action by rotating the pulsator at high speed to cause the upper and lower circulating water flows to penetrate into the laundry to obtain the washing power. The first purpose is to do.

Further, according to the present invention, the washing power obtained by placing an article to be washed on a shelf at the time of washing and penetrating an upper and lower circulating water flow through the article to be washed is arbitrarily changed by changing the rotation speed of the pulsator. A second object is to provide a fully automatic washing machine in which the water flow pressure can be set according to the type of item and the degree of dirt.

Further, according to the present invention, when the laundry is washed, the laundry is put on a shelf and the pulsator is rotated at a high speed to cause a pumping action, so that a plurality of powerful jets from the nozzles generated thereby are exposed to the laundry. A third object is to provide a fully-automatic washing machine that further obtains detergency.

Further, the present invention provides a fully automatic washing machine in which a dehydration tub is rotated during washing to cause a pumping action, and an upper and lower circulating water flow generated thereby is passed through an article to be washed to obtain washing power. Is the fourth purpose.

A fifth object of the present invention is to provide a fully-automatic washing machine which dries items to be washed on the shelf after washing and spin-drying with a tornado-like wind generated by rotating the pulsator at a high speed.

[0009]

[Means for Solving the Problems] To achieve the above first object, a first means is a water tub which includes a main body of a washing machine and a dehydration tub for washing and dehydrating, and is supported by the main body via a suspension. And a water passage that connects the pump chamber formed by the pulsator and the bottom of the dehydration tank and the injection port at the top of the dehydration tank, and is detachably mounted inside the dehydration tank. When a laundry is placed on the shelf, the pump is operated by rotating the pulsator at a high speed during washing, and the circulating water flow from the injection port that is generated by this causes the washing power to penetrate the laundry. It will be obtained.

The second means for achieving the second object of the present invention is to change the rotation speed of the pulsator by changing the number of revolutions of the pulsator, which is the detergency obtained by passing the circulating water flow through the object to be washed. The water pressure should be adjusted according to the type of laundry and the degree of dirt.

Further, a third means for achieving the third object of the present invention comprises a nozzle having a plurality of holes at the injection port.

Further, a fourth means for achieving the fourth object of the present invention is to provide an opening in the upper part of the water tub for dropping washing water toward the inside of the dehydration tub, and removing the opening during washing. A pump action is caused by rotating the water tank, and the circulating water flow generated by this is dropped from the opening and penetrated into the article to be washed to obtain a washing force.

A fifth means for achieving the fifth object of the present invention is to wash the articles to be washed on the shelves after washing and dehydration.
It is configured to be dried by a tornado-like wind generated by rotating the pulsator at high speed.

[0014]

The operation of the first means is that the pulsator attached to the washing shaft is rotated by the drive motor in the washing and rinsing steps, and the pump action is caused by the pump vanes formed in the pump chamber. At this time, the upper and lower circulating water circulates while penetrating the article to be washed fixed on the shelf installed in advance in the dehydration tank. The force of this water flow cleans up the dirt evenly, and it can be washed without excessive mechanical force caused by the pulsator or damage or shrinkage caused by the entanglement between the items to be washed.

In the second means, during the washing and rinsing strokes, the pulsator attached to the washing shaft is rotated by the drive motor and the pump blades formed in the pump chamber cause a pumping action. At this time, the upper and lower circulating water circulates while penetrating the article to be washed fixed on the shelf installed in advance in the dehydration tank. By removing the dirt evenly by the force of this water flow, and further changing the rotation speed of the pulsator arbitrarily, the flow rate can be adjusted and the water flow pressure can be adjusted according to the type of the object to be washed and the degree of dirt.

In the third means, in the washing and rinsing strokes, the pulsator attached to the washing shaft is rotated by the drive motor, and the pump blades formed in the pump chamber cause a pumping action. At this time, the upper and lower circulating water circulate while penetrating through the article to be washed fixed on the shelf installed in advance in the dehydration tank, but at this time, the nozzle provided at the outlet of the water passage makes the entire article to be washed. You can effectively spray water.

The fourth means is that, in the washing and rinsing steps, by rotating the dehydration tank, the water in the water tank is lifted up by the centrifugal force of the dehydration tank to lift up the gap formed by the dehydration tank and the water tank. It is injected from the top into the dehydration tank to form a series of circulating water streams. This circulating water flow makes it possible to wash the article to be washed, or to perform effective rinsing with a synergistic effect of centrifugal force and circulating water when rinsing.

In the fifth means, during the washing and rinsing strokes, the pulsator attached to the washing shaft is rotated by the drive motor, and the pump vanes formed in the pump chamber cause a pumping action. At this time, the upper and lower circulating water circulates while penetrating an object to be washed which is fixed on a shelf installed in advance in the dehydration tank, and uniformly removes dirt by the force of this water flow. Further, after the spin-drying, the laundry can be dried by the tornado-like wind generated by rotating the pulsator at a high speed while the laundry is placed on the shelf.
