Description

Stirring device of the washing machine

The present invention relates to a washing machine, and more particularly, to an agitator of a washing machine, which is installed in a washing tank and washes laundry therein while flowing washing water.

In general, a washing machine is a washing process that is set in advance, for example, a water supply stroke for supplying washing water to a washing tank, a washing stroke for washing laundry through the wash water supplied through the water supply stroke, and a rinsing rinsing for the laundry washed through the washing stroke. And a dehydration stroke for dewatering the laundry washed cleanly through the rinsing stroke.

In the conventional washing machine configuration having a series of washing process described above, as shown in FIG. 1, a storage tank 2 in which a certain amount of washing water is freshly installed is installed inside the rectangular body 1, and the storage tank 2 is washed. It is configured in a cylindrical shape so as not to interfere with the rotational flow generated in the process, which is suspended from the inside of the main body 1 by the hook rod 7.

In addition, the cylindrical washing tank 3 is installed inside the water storage tank 2 in a rotatable state. The washing tank 3 is formed with a myriad of through holes 3a penetrating the inner and outer circumferential surfaces thereof, and these through holes 3a are Washing water supplied into the washing tank (3) flows into the water storage tank (2), whereby the water level of the washing tank (3) and the water storage tank (2) is matched, and these through holes (3a) to the wet laundry in the dehydration process Contaminated washing water and debris generated from the discharge to the reservoir (2).

On the other hand, a balance weight (not shown) is installed on the upper inner circumferential surface of the washing tank 3 to mitigate the vibration of the washing tank 3 when dewatering.

Then, the rotating body 4 of the stirring device having a plurality of wings (4a) on the inner bottom of the washing tank (3) is installed so that the forward and reverse rotation, the rotating body (4) is to be forward and reverse rotation in the washing process, The washing water supplied into the washing tank 3 is circulated, and the laundry is washed as if the laundry is rubbed with each other.

In addition, a power switching means 6 is installed in the center of the bottom surface of the water storage tank 2, the power switching means 6 is a washing shaft (6a) and dewatering shaft (6b) is formed on the upper, respectively, the washing The shaft 6a is coupled to the rotating body 4 inside the washing tub 3, the dehydration shaft 6b is coupled to the bottom of the washing tub 3, and the power switching means 6 is Forward and reverse rotation by the motor (5) combined with the bottom surface.

In other words, when the disk-shaped rotating body 4 is rotated, the washing water is circulated by each of the blades 4a, which are radially projected on the upper part of the rotating body 4, and the laundry is rotated by the rotating flesh in the process. This rubs against each other.

In addition, when the rotating body 4 is rotated forward and reverse during the washing process, the storage tank 2 is vibrated by the rotation of the washing tank 3 and water, the storage tank 2 is the main body (1) through the hook rod (7) Vibration is alleviated by resilient hanging inside.

In the conventional washing machine, washing is not only deteriorated because laundry is twisted with each other while the laundry is moved to the center as shown in the arrow of FIG. 1 while using the rotating water flow generated when the rotating body 4 is reversely rotated. This leads to extremely low washing efficiency. That is, when the rotational water flows, the laundry is rotated by the rotating water and rubs each other in this process, and the washing proceeds. At this time, the laundry is twisted and twisted at the same time as the laundry is moved to the center. This twisted laundry is not rubbed well by the rotational flow, so there is a problem that the washability is greatly reduced and thus the washing time is long.

The present invention was created in view of the above problems, by installing a punch rod operated by a rotating body on one side of the washing tank to generate a vortex in the heart-shaped water flow generated by the rotating body, thereby preventing the twist of the laundry At the same time, the object of the present invention is to provide a stirring device for washing the laundry by applying a direct impact on the laundry to greatly improve the washing power.

In addition, the reservoir 11 is provided with a damper (16a) formed on all four sides of the lower portion of the outer peripheral surface is suspended in the interior of the body 10, which is a plurality of hook rods in all directions on the inner upper portion of the body (10) It is coupled and the lower end of each hook rod 16 is connected to the upper portion of the damper (16a). When vibration occurs in the reservoir 11 in this state, each damper (16a) is to mitigate it.

In addition, the washing tank 12 containing the washing water and the laundry is rotatably installed in the water storage tank 11, and the washing tank 12 has a large number of through-holes 12a communicating with the water storage tank 11 on the side surface. And the wash water to be supplied into the washing tank 12 flows to the reservoir (11). That is, when the wash water is supplied to the inside of the washing tank 12, the washing water flows toward the water storage tank 11 through each through hole 12a so that the water level of the washing tank 12 and the water storage tank 11 coincide.

Next, an agitator 20 corresponding to the washing shaft 15a of the power switching means 15 that is operated by receiving power of the motor 15b is installed in the washing tank 12, and the washing shaft 15a is provided. A disk-shaped rotating body 21 is formed to be coupled to the upper surface of the rotating body 21, a plurality of wings (21a) for generating a rotational flow is formed, between the reservoir 11 and the washing tank 12 The drive cam 15c is coupled to the washing shaft 15a.

In addition, a horizontal cam 22 corresponding to the driving cam 15c is installed at a bottom portion between the washing tank 12 and the water storage tank 11, and the horizontal cam 22 is provided with a washing shaft 15a by a spring 22a. ) Is always in contact with the drive cam (15c) of the) to continuously move the left and right.

In other words, while the washing tub 12 rotates, the outer cam drive cam 15c moves the horizontal cam 22 to the left and right, and the horizontal cam 22 vertically operates the vertical cam 23 at the upper portion thereof. The vertical cam 23 generates turbulence in the water in the washing tank 12 by horizontally reciprocating the punch rod 26 on one side of the washing tank 12.

In addition, when the punch rods 26 of the stirring device 20 are installed at all sides of the washing tank 12, the water is more effective in turbulent water flow.

The above description is only one embodiment of the present invention, the configuration of the present invention can be changed as many within the scope of the invention.

Referring to the operation of the present invention configured as described above in detail.

In the washing machine configured as described above, laundry is contained in the washing tank 12 and a water supply administration is performed. When water is stored by the amount specified in the water storage tank 11, the washing administration is continuously performed for a predetermined time. When the forward and reverse rotations (15b), the rotational force thereof is transmitted to the power switching means 15 and at the same time decelerated at a predetermined speed in the power switching means 15, then the reverse rotational power is rotated through the washing shaft (15a) It is transmitted toward the whole 21, and when the rotating body 21 is rotated forward and reverse, the washing water causes a rotational flow and washing proceeds as if the laundry is rubbed with each other by the rotational flow.

In other words, when the disk-shaped rotating body 21 is rotated, the washing water is circulated by the respective blades 21a protruding radially on the upper part of the rotating body 21, and the laundry is rotated by the rotating flesh in this process. Washing proceeds as if this is rubbed together.

On the other hand, while the washing shaft 15a of the power switching means 15 is rotated and the driving cam 15c coupled thereto is rotated, and the driving cam 15c moves the horizontal cam 22 of one side to the left and right. The horizontal cam 22 vertically operates the vertical cam 23 of the upper portion thereof, and the vertical cam 23 reciprocates the punch rod 26 on one side of the washing tank 12 horizontally. In addition, the turbulence is generated in the water in the washing tank 12 to disperse the laundry concentrated in the center by the rotating body 21 and at the same time, the laundry is impacted to maximize the washing effect.

In addition, when the rotating body 21 is reversely rotated in the washing process, the storage tank 11 is vibrated by the circulation of the washing tank 12 and water, and the storage tank 11 is the main body 10 through the hook rod 16. Vibration is alleviated by resilient hanging inside.

After the washing stroke is completed, the washing water is first drained, and then a rinsing stroke is performed. During the rinsing cycle, the normal water supply stroke is progressed and the motor 15b is reversely rotated, and its rotational force is transmitted to the power switching means 15. At the same time, after decelerating in the power switching means 15, the forward and reverse rotational power is transmitted to the rotating body 21 through the washing shaft 15a. At this time, as the rotating body 21 is reversed and rotating, the washing water flows to rinse the laundry cleanly. After a predetermined time, the contaminated water is drained to the outside through the drainage means.

On the other hand, while the washing shaft 15a of the power switching means 15 is rotated and the driving cam 15c, the horizontal cam 22, and the vertical cam 23, which are coupled thereto, are sequentially linked to one side of the washing tank 12. By reciprocating the punch rod 26 horizontally to generate turbulence in the water in the washing tank 12, the laundry concentrated in the center by the rotating body 21 is dispersed in all directions and the shock is transmitted to the laundry. The rinsing effect is maximized.

In the rinsing cycle, the above process is repeated several times, so that the laundry detergent is completely removed.

After the rinsing cycle is repeatedly completed, the dehydration stroke proceeds. When the motor 15b is rotated at a high speed in one direction in the dehydration process, the washing shaft 15a and the dewatering shaft are rotated together by the power switching means 15 at a high speed. The washing tub 12 is rotated at high speed. When the washing tank 12 is rotated at a high speed, centrifugal force is applied to the laundry to spread the laundry toward the inner circumferential surface of the washing tank 12, and the washing water contained in the laundry is dehydrated. In addition, the dewatered wash water is discharged toward the water storage tank 11 along a plurality of through-holes 12a formed on the inner and outer circumferential surfaces of the washing tank 12, and the wash water thus discharged is drained to the outside through the drainage means.

The present invention by installing a punch rod 26 is operated by a plurality of cam means on one side of the washing tank 12 to generate turbulence in the heart-shaped water flow generated by the rotating body 21, laundry in the washing stroke and rinsing stroke It prevents twisting and at the same time directly impacts the laundry, which greatly improves the washing power of the laundry.
