Pulsator in washing machine

The present invention relates to a pulsator of a washing machine, and more particularly, to wash the washing water upward of the pulsator repeating the normal and reverse rotation during the washing process to prevent the laundry from concentrating on the center of the pulsator while washing It relates to a pulsator in a washing machine that maximizes efficiency.

In general, a washing machine is a product for removing various contaminants attached to clothes, bedding, etc. by using the emulsion action of the detergent and the friction action of the water flow due to the rotation of the pulsator and the impact action of the pulsator on the laundry. By detecting the amount and type of the laundry by the sensor, the washing method is automatically set, the washing water is supplied to the appropriate level according to the amount and type of the laundry, and the washing is performed under the control of the microcomputer.

In the conventional fully automatic washing machine, as illustrated in FIG. 1, an outer tub 2 for storing wash water is installed inside the main body 1 forming an outer appearance, and the outer bottom of the outer tub 2 is driven by power. A motor member 3 is installed, and a clutch unit for driving a pulsator or a washing / dehydration tank to be described later by receiving a driving force from the motor member 3 through the belt 4 on the outer bottom of the outer tub 2 ( 5) is mounted, the inside of the outer tub (2) is combined with a washing combined dehydration tank (6) rotatably so that the laundry can be dewatered by the centrifugal force due to the rotation of the clutch (5).

In addition, a balancer 7 for maintaining a horizontal state of the combined laundry dehydration tank 6 is installed on the upper side of the combined laundry dehydration tank 6 so that the laundry rotates even when the laundry is depressed to one side. On the bottom surface of the tank 6, a pulsator 8 is rotatably installed to form a water stream in the wash water contained in the combined washing and dehydration tank 6 to perform the washing process.

Here, when looking at the structure of the pulsator 8, as shown in Fig. 2 is formed a circular rotating body 8a which is interlocked with the washing shaft 5a of the clutch portion 5, the upper surface of the rotating body 8a At least one wing 8b is formed therein and a plurality of jet holes 8c through which washing water is jetted to the periphery thereof are formed.

In addition, the water supply for detecting the water level of the wash water stored in the outer tank (2) by the water level sensor (not shown) in the upper portion of the main body 1 to supply the wash water according to the laundry in the outer tank (2) The device 9 is installed.

In addition, a drainage means 10 for discharging the contaminated washing water generated at the time of washing and rinsing is installed at one lower side of the outer tub 2, and a pulsator 8 is disposed inside the washing / dehydration tank 6. A guide tube 11 for guiding the water flow upward as the rotation is provided is provided.

In the conventional fully automatic washing machine configured as described above, laundry and detergent are put in the dehydration tank 6, and operation conditions are selected by an operation unit (not shown), and then the washing machine is operated to wash the water into the tub 2 through the water supply device 9. When the water supply stroke to be supplied is progressed and the wash water supplied to the outer tub 2 is completed by the designated amount, the motor member 3 starts to rotate, and the rotational force of the motor member 3 causes the belt 4 to rotate. It is transmitted to the clutch unit 5 through the clutch unit 5, and the clutch unit 5 receives the rotational force of the motor member 3 to decelerate at a predetermined speed, and then rotates the pulsator 8 to wash in the dehydration tank 6. When the number is returned, the laundry administration proceeds.

That is, as the pulsator 8 rotates, the washing water in the dehydration tank 6 rises at the edge of the rotor 8a by the vanes 8b of the rotor 8a. While forming a heart-shaped up and down water flow descending to the center portion, the washing stroke is discharged upward through the jet hole (8c) of the rotating body (8a) is sprayed upward.

Then, when the washing operation is finished, the solenoid valve (not shown) installed in the lower part of the outer tank 2 is turned on (opened) and the contaminated washing water stored in the outer tank 2 and the dehydration tank 6 is removed. The drainage stroke discharged to the outside through the drainage means 10 is in progress.

Thereafter, when the drainage stroke of the washing water is completed, the solenoid valve is turned off and the rinsing water is supplied to the inside of the outer tub 2 through the water supply means 9 to reach the water level required for rinsing the laundry. Like the washing stroke, the pulsator 8 rotates clockwise and counterclockwise in the clockwise and counterclockwise directions according to the driving force of the clutch unit 5 that receives the driving force of the motor member 3 to remove contaminants and detergents from the laundry. Rinsing rinse stroke is in progress. At this time, the washing water is discharged to the laundry through the jet hole (8c) of the rotary body (8a) to effectively rinse the contaminants and detergent of the laundry.

When the final rinsing stroke is repeated by repeating the above rinsing cycle several times, the rinsing-completed wash water stored in the outer tank 2 and the dehydrating tank 6 is discharged to the outside through the drainage means 10, wherein the clutch As the dehydration tank 6 rotates in one direction according to the driving force of (5), a dehydration stroke for dewatering the wash water in the dehydration tank 6 and the wash water permeating the laundry proceeds.

However, in the conventional washing machine, since the ejection hole 8c of the pulsator 8 is formed in the entire upper surface of the rotating body 8a, the ejection power of the washing water is extremely weak, so that the washing machine cannot penetrate into the laundry. As a result, there was a problem that can not effectively wash the contaminants and detergent in the laundry.

The present invention is to solve the above problems, by forming a spout of a predetermined diameter in the central portion of the pulsator, by rinsing the washing water downward through the spout to the top, maximizing the discharge power of the wash water It is an object of the present invention to provide a pulsator of a washing machine that can effectively wash and rinse contaminants and detergents in laundry.
