Description

Pulsator in washing machine

The present invention relates to a pulsator of a washing machine. More specifically, the washing water is sprayed to both sides of the pulsator, which repeats the normal and reverse rotation during the washing process, so that the laundry is not concentrated on the upper center of the pulsator. The present invention relates to a pulsator of a washing machine that greatly improves 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.

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. Washing stroke to form a heart-shaped up and down water flow descending to the center is in progress.

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. In accordance with the driving force of the clutch unit 5 received the driving force of the motor member 3 as in one washing stroke, the pulsator 8 rotates clockwise and counterclockwise in the forward and reverse directions to remove contaminants and detergents from the laundry. Rinsing rinse stroke is in progress.

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, such a conventional washing machine is not only deteriorate in washability because laundry is twisted with each other while the laundry is moved to the center in the process of washing using the rotational water generated when the pulsator 8 is reversely rotated. The washing efficiency is extremely low. That is, when the rotational water flows, the laundry is rotated by the rotational water and is rubbed with each other in this process, and 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 was a lot of problems, such as the washability is greatly reduced and the washing time is long accordingly.

The present invention is to solve the above problems, to form a spout so that the washing water sucked into the interior from the inlet hole in the upper center of the rotating body of the pulsator to the upper side of the dehydration tank, washing in the spout By forming two jet holes so that the water can be ejected in both directions, the laundry is jetted from the two jet holes to prevent the laundry from being entangled, as well as from the jets to the laundry being circulated by the rotor blades. The object of the present invention is to provide a washing machine pulsator which greatly improves washing efficiency by hitting laundry by colliding the jetted washing water.
