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.

In addition, a stirring device 4 having a plurality of wings 4a on the inner bottom of the washing tank 3 is installed to be capable of forward and reverse rotation, and the stirring device 4 is rotated forward and backward in the washing process, and the washing tank 3 ) Wash the water supplied to the inside, and the laundry is washed as if the laundry is rubbed by 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 stirring device 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 stirring device 4 is rotated, the wash water is circulated by each of the blades 4a radially projecting on the upper part of the stirring device 4, and in the process, the laundry is rotated by the rotating flesh. This rubs against each other.

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

However, in the conventional washing machine, washing is deteriorated because the 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 stirring device 4 is rotated forward and backward. However, 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 disadvantage that the washability is greatly reduced and thus the washing time is long.

In addition, since the stirring device 4 washes the laundry using only a simple rotary water flow, there is a problem such that washing efficiency is lowered.

The present invention has been made in view of the above problems, the laundry tank wall is installed in the at least one vortex generating means driven by the rotating body of the stirring device to the tangled laundry to be entangled in its center The purpose of the present invention is to provide an agitator of the washing machine to prevent washing, shortening the washing time and maximizing washing efficiency.
