Field of the Invention The present invention relates to a washing machine for washing clothes and the like, and more particularly to a washing machine for circulating water by forcibly circulating water stored in a lower portion of a washing tub to an upper portion of the washing tub and ejecting the water. The present invention relates to a washing machine that has made it possible.

[0002]

2. Description of the Related Art FIG. 25 is a diagram showing the internal structure of a conventional washing machine driven by an inner tub. In general, as shown in FIG. 1, a motor-directly-connected washing machine includes a washing machine case 10, a washing tub 20 provided inside the washing machine case 10 for washing laundry, and a washing tub 20. The washing machine case 1
0 and four suspension members 30 functioning as a damper, and provided at a lower portion of the washing tub 20,
3 and a drive motor 40 for rotatingly driving the drive motor 3.

The washing tub 20 is fixed so as to be hung inside the washing machine case 10 via the hanging member 30 and stores washing water.
2 and an inner tank 23 connected to the drive motor 40 and rotated.

A drain hose 26 and a drain valve 27 for draining washing water are provided below the outer tub 22, and a pulsator 25 for increasing washing efficiency is provided on the bottom of the inner tub 23. Provided. Therefore, the washing tub 20 rotates while the inner tub 23 is rotated by the operation of the drive motor 40 in a state where the outer tub 22 is fixed to be suspended from the washing machine 10 via the suspending member 30. This is what washing does.

The operation of the conventional washing machine driven by the inner tub constructed as described above will be described as follows.
First, when the user opens the door 11 of the washing machine case 10 and then puts laundry and detergent into the inner tub 23 and then operates the washing machine, water is supplied into the washing tub 20. The outer tub 22 and the inner tub 23 are filled to a certain height, and then the driving motor 40 operates to rotate the pulsator 25 and the inner tub 23 to perform washing.

[0006] As described above, when a predetermined time has elapsed after washing, the drive motor 40 stops operating, the drain valve 27 provided at the lower part of the outer tub 22 is opened, and the washing tub 20 is opened. Is drained to the outside through a drain hose 26. When drainage is completed in this way,
After water is supplied to the washing tub 20 again and is filled to a certain height, a rinsing operation is performed. The rinsing operation is usually performed two to three times, and is performed in the same operation as the washing operation, but the time for operating the drive motor 40 is shortened.

As described above, when the washing and rinsing operations are completed, only the inner tub 23 rotates at a high speed, and a dehydrating operation for removing water contained in the laundry proceeds. That is, when the inner tub 23 rotates at a high speed, the water contained in the laundry is centrifugally applied to cause the inner tub 23 to rotate.
After moving to the outer tank 22 through the small hole formed in
The water is drained to the outside through the drain hose 26.

However, in the above-described conventional washing machine, when the inner tub 23 is driven to rotate, the washing water bubbles are generated when the inner tub 23 is driven to rotate while the washing tub 20 is rotated forward or backward in a vertical state. There is a problem that the flow occurs in a symmetrical manner, causing the laundry to be entangled with the laundry, and the secondary water flow generated by the pulsator 25 is not complicated, so that a uniform washing operation cannot be performed and the washing performance is deteriorated.

The washing machine according to the prior art as described above can perform agitation rinsing only when the washing tub 20 is filled with washing water up to a certain height to perform a rinsing process. Of course, water is used,
As a result, there is a problem that the time for water supply and drainage becomes longer, and the whole washing time becomes longer.

[0010] Further, the prior art washing machine as described above,
Because there is no filtration device to collect lint,
Since lint or fluff generated in the washing process remains on the laundry as it is, there is also a problem that there is a limit in realizing high detergency.

[0011]

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 shows a washing machine according to a first embodiment of the present invention. FIG. 1 is a sectional view showing the structure of the washing machine, FIG. 2 is a sectional view showing operating states of a pump and a three-way valve, and FIG. It is sectional drawing which shows the use condition of a body type pump.

The washing machine according to the first embodiment of the present invention has a washing machine case 50 having a door 55 provided on an upper portion thereof, and is mounted in the washing machine case 50 at a predetermined angle (θ) with respect to a vertical direction. A washing tub 60 for washing the laundry in the inner tub 65;
A suspending member 57 whose upper end is fixed in the washing machine case 50 and whose lower end is fixed to the washing tub 60 so as to be obliquely positioned therein, and is provided below the washing tub 60, And a drive motor 75 for driving the inner tub 65 of the washing tub 60.

The washing tub 60 has an outer tub 61 obliquely fixed in the washing machine case 50 via the hanging member 57.
And an inner tub 65 rotatably connected to the drive motor 75 in the outer tub 61 and provided with a pulsator 66 for increasing washing efficiency. in this way,
The washing tub 60 including the outer tub 61 and the inner tub 65 is attached obliquely in the vertical direction at an inclination angle (θ) in the range of 0 ° <θ <30 °.

As described above, when the washing tub 60 is installed obliquely, the washing degree is improved and the washing deviation is reduced. When the inner tub 65 rotates, the internal water flow is caused by gravity, centrifugal force, The asymmetrical configuration of the inclined inner tub surface is used to generate a complicated foam flow, thereby improving the detergency of the laundry.

On the other hand, an inner tank 65 is provided above the outer tank 61.
A tab cover 62 made of an annular disk is provided so that the centrifugal force caused by the rotation of the 槽 can cause centrifugal permeation washing in which the water flow rising along the wall surface of the outer tub 61 falls again to the inner tub 65 like waterfall. A drain outlet 63 is located on the lower side of the bottom of the outer tub 61, and a drain hose 64 is connected to the outside of the washing machine case 50 from the drain outlet 63.

In particular, at the tip of the drain hose 64,
In order to force the water in the washing tub 60 to circulate to the upper side of the washing tub 60, a circulation hose 70 connected to an upper side of the inner tub 65 is branched. That is, at the time of washing or rinsing, the washing water is circulated through the circulation hose 70 so that water can be supplied from the upper part of the washing tub 60 to the inside of the inner tub 65, and at the time of drainage, the washing water is drained through the drain hose 64 side. It has become.

The circulating hose 70 is connected to the outer tub 6
1 is connected to the lower side of the tab cover 62 along a circulation passage 71 formed integrally with the side surface of the inner tank 6.
In order to allow the washing water to pass through the inside of the
Is fixedly connected to the nozzle 74. Of course, the circulation passage 71 may be connected to the outer tub 61 without being formed integrally with the outer tub 61 by fixing the circulation passage 71 to the side surface.

At the point where the drain hose 64 and the circulation hose 70 are branched, a drain hose 64 or a circulation hose 70 is provided.
A three-way valve for selectively opening one of the two is provided, and a pump 73 for forcibly circulating or discharging the washing water is provided upstream of the three-way valve.

FIG. 2 is a schematic diagram showing the pump 73 and the three-way valve 72. As shown in FIG.
Is a centrifugal pump into which washing water flows into the center of the impeller 73a, and the three-way valve 72 is provided at the outlet side of the casing 73b where the drain hose 64 and the circulation hose 70 are branched.

The three-way valve 72 switches the flow path by rotating a valve plate 72b by a solenoid actuator 72a operated by electronic control. Therefore, the pump 73 forcibly circulates water through the circulation hose 70 and the circulation passage 71 during permeation washing or permeation rinsing,
During the draining process, water is discharged through the drain hose 64.

FIG. 3 is a configuration diagram when an integrated pump is used. As shown in the figure, the integrated pump 80 is composed of a centrifugal pump 83 and an axial pump 84 in one casing 8.
1 is rotatably connected to one motor shaft 82, so that suction and discharge pressure is generated on the centrifugal pump 83 side during forward rotation, and suction and discharge pressure is generated on the axial flow pump 84 side during reverse rotation. You.

When a circulation hose 85 is connected to the centrifugal pump 83 to circulate the washing water, a drain hose 86 is connected to the axial pump 84. Therefore, when the integral pump 80 rotates forward, pressure is generated by the centrifugal pump 83, so that the washing water flows to the upper side of the washing tub through the circulation hose 85. Since pressure is generated on the side, the washing water is discharged to the outside through the drain hose 86.

When such an integrated pump 80 is used, it is not necessary to provide a separate three-way valve as in the above embodiment, and the two suction side hoses 87 are respectively connected to the bottom of the outer tank. Alternatively, a branch may be provided from one hose connected to the bottom surface of the outer tank. Also, without using the centrifugal pump of FIG. 2 or the integrated pump of FIG. 3, a circulation hose and a drainage hose are separately connected to the bottom of the outer tank, and a circulation pump or a drainage pump is separately provided for each hose. Can also.

The operation of the washing machine according to the first embodiment of the present invention will be described as follows. When the washing machine is operated, an appropriate amount of washing water is supplied to the washing tub 60. At this time, since the washing tub 60 is inclined, the washing water is inherently asymmetric with respect to the vertical direction.

When the drive motor 75 is operated in such a state, the inner tank 65 is driven to rotate. At this time, since the inner tank 65 is disposed obliquely with respect to the vertical direction in which gravity acts, the water flow is formed in an asymmetric form due to the interrelationship of gravity, centrifugal force, and the inclined inner tank surface, and is complicated. A primary water stream with a smooth foam flow is generated. In addition, since the pulsator 66 in the inner tub 65 is also positioned obliquely, not only the centrifugal force but also the lift force is simultaneously generated in the washing water, so that the primary water flow and the secondary water flow are combined in a complex asymmetric form. Flowed.

When the inner tub 65 rotates at a certain speed or higher, the tub cover 62 is provided on the upper portion of the outer tub 61, so that centrifugal permeation washing can be performed by rotating the inner tub 65. That is, the water flow that has risen along the wall surface of the outer tub 61 falls through the tub cover 62 into the inner tub 65 like waterfall, and at the same time, a complicated bubble flowing water flow is generated in the inner tub 65, By increasing the frictional force between water and the laundry, the washing power can be increased.

When the pump 73 is driven at the same time,
Since the washing water can also be forcibly circulated to the circulation hose side, a higher washing power can be expected by spraying water into the inner tub 65 through the nozzle 74 after the centrifugally transmitted water flow. .

Therefore, when the washing process is performed by the washing machine of the first embodiment, the washing tub 60, that is, the inner tub 65 is inclined, so that a complicated asymmetric foam flow is generated and the inner tub 65 is rotated. Since both the centrifugal permeation washing and the circulation permeation washing by the operation of the pump 73 are possible, the generation of a symmetrical water flow in a certain direction is minimized, and the cloth is not entangled with the laundry. Since the frictional force acts evenly, the washing power of the laundry can be improved after all.

On the other hand, the operation of spraying the washing water from above through the circulation hose as described above can exert a higher effect during the rinsing process. That is, unlike the related art, the washing rinsing can be simultaneously performed without spraying the washing water from the upper portion of the washing tub 60 without depending on the stirring rinsing by the rotation drive of the inner tub. The effect will be even higher.

In the state where the washing tub 60 is inclined, stirring and permeation rinsing can be performed while circulating the washing water continuously from the lowermost surface of the washing tub 60 to the upper side. A rinsing effect can be expected.

That is, in the case where the inner tub 65 is driven to rotate to perform only stirring rinsing, sufficient water is supplied to the height of the laundry, and then the rinsing process is performed using the frictional force between the washing water and the laundry. However, in addition, in the present invention, the washing tub 60 is inclined and the water in the lower part is circulated to the upper part and the stirring rinsing and the permeation rinsing are simultaneously performed while spraying water. The rinsing power can be improved.

Therefore, if it is assumed that 160 L of water is used in the case of ordinary stirring and rinsing, when the stirring rinsing and the permeation rinsing are simultaneously performed as in the above embodiment, the rinsing power is about 10% while using 50 L of water. Can be raised.

As described above, since the rinsing process is performed using a small amount of washing water, the water supply time is shortened,
Since the drainage is completed in a shorter time at the time of drainage, the time required for washing can be shortened, and the number of times of rinsing can be increased within the same time to increase the rinsing effect.

FIG. 4 is a block diagram showing a washing machine according to a second embodiment of the present invention. In the first embodiment of the present invention, the circulation channel is provided on the washing tub 60 side.

Although FIG. 6 shows the tab cover 180 provided with two nozzles 183, the tab cover 180 may be formed symmetrically with four or six if necessary.

In the third embodiment of the present invention, since the washing tub 160 is obliquely mounted at a certain angle, when the inner tub 165 is driven to rotate, a complicated asymmetric bubble flow is generated. Further, when the inner tub 165 rotates at a certain speed or higher, centrifugal transmission washing can be performed through the inner surface of the tub cover 180. When the pump 173 is driven, the circulation hose 170, the circulation pipe 172, and the tab cover 18
