Description

Stirring device of the washing machine

The present invention relates to a stirrer of a washing machine, and more particularly, to a stirrer of a washing machine capable of maximizing washing efficiency while preventing laundry from being entangled at the top of the stirrer when the stirring device is rotated.

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 water generated in the process, which is installed hanging inside the main body 1 by a hook rod (not shown).

In addition, the cylindrical washing tank 3 is installed inside the water storage tank 2 in a rotatable state, and the washing tank 3 has a myriad of through holes 3a passing through the inner and outer circumferential surfaces thereof, and these through holes 3a are formed. 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 circulation of the washing tank 3 and water, and the storage tank 2 is elastically inside the main body 1 through a hook rod. Vibration is alleviated by hanging up.

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 in the process of washing by using the rotational water generated when the rotating body 4 is rotated forward and backward, and thus washing efficiency is reduced. This is extremely degraded.

That is, when the rotational water flow is generated by the rotating body 4, the laundry is rotated by the rotating water and rubbed with each other in this process, and the washing proceeds. At this time, the laundry is twisted to the center by the rotational water and twisted with each other. Twisted, the twisted laundry is not easily rubbed by the rotational flow, so the washability is greatly reduced and thus the washing time is long.

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

Therefore, the present invention has been made in view of the above problems, while generating a rotary water flow as a blade of the stirring device and at the same time forming a jet wing therein so that water is jetted to the center of the stirring device, twisting the laundry On the other hand, an object of the present invention is to provide a stirring device of a washing machine, which greatly improves washing efficiency by tapping laundry by hydraulic power ejected by the jetting wing.
