The present invention relates to a washing tank of a fully automatic washing machine, and more particularly, it is possible to smoothly flow up and down laundry when washing in a fully automatic washing machine, and to increase the washing effective area to improve washing efficiency.

In the conventional fully automatic washing machine, as shown in FIG. 1, the top cover 15 is installed on the upper portion of the main body 14, and rotatably inside the outer tub 5 installed and supported in the main body 14. A washing tank 1a formed of a cylindrical portion 2a and a base 4a is installed, and a base 4a is mounted below the motor 11 and the washing tank 1a, which are mounted at the bottom center of the outer tank 5 to generate power. Between the shaft 12 penetrating the housing 16 is installed in the center of the lower end in the outer tub 5, the shaft receiving the power of the motor 11 on the shaft 12, the lower portion in the housing 16 A bearing 17 for smoothly rotating the 12 is provided.

In addition, a fluid balancer 18 is installed on the inner circumferential surface of the upper end of the cylindrical portion 2a of the washing tank 1a to maintain the balance of the washing tank 1a during washing and dehydration, and protrudes in the vertical direction on the inner circumferential surface of the cylindrical portion 2a. A plurality of washing protrusions 19 are formed, and a plurality of washing wings 13 are radially installed on a bottom surface of the base 4a coupled to the bottom of the cylindrical portion 2a by seaming. A hub 7 having a plurality of wings 7a radially is installed at the lower end of the base 4a, and a cap 20 is installed at the center of the lower end of the base 4a.

Therefore, when laundry is put into the washing tank 1a during washing, water supply is started by a predetermined algorithm, and when the predetermined water level is reached, the motor 11 mounted at the lower center of the outer tank 5 is driven, thereby driving the motor 11. The power is transmitted to the washing tank (1a) through the shaft 12, the washing tank (1a) is rotated forward and reverse to wash, and when dehydration, after draining the water in the outer tank (5) washing tank (1a) Spinning in one direction at a high speed gives centrifugal force to the laundry to perform dehydration.

However, when washing in such a conventional fully automatic washing machine, washing water in the circumferential direction is generated by the washing vanes 13 radially provided on the bottom surface of the base 4a in the washing tank 1a. In (1a), the upper and lower portions of the cylindrical portion (2a) is a pressure difference caused by the flow rate difference generates a force to pull down from the upper portion, but a plurality of formed in the vertical direction in the vertical direction to the inner peripheral surface of the cylindrical portion (2a) Since the washing flow in the circumferential direction generated by the washing projections 19 is generated at the same time to weaken the force pulling down to the lower portion, the up and down flow of the laundry is not made smoothly, and the load is caused by the washing projections 19. Generated and the washing efficiency was lowered.

In addition, water flow is generated by the rotation of the washing protrusion 19 in the cylindrical portion 2a and the hub 7 installed at the lower end of the base 4a in the washing tank 1a, and thus, between the outer tank 5 and the washing tank 1a. As the water rises, the water level in the washing tank 1a is lowered from A to B so that the flow space of the washing is reduced, and the outer water level of the washing tank 1a rises to C, so that the washing water overflows to the outside of the outer tank 5 There have been many problems, such as overflow.

The present invention is to solve the above problems, it is possible to smooth the up and down flow of the laundry when washing in a full automatic washing machine to reduce the deviation of the laundry, and to increase the effective volume of the laundry by introducing water outside the washing tank to the inside The purpose of the present invention is to provide a washing tub of a fully automatic washing machine that can improve washing performance and prevent water from being scattered during washing.

In order to achieve the above object, the present invention is a cylindrical portion of the washing tank in which a plurality of dehydration holes are formed, and the base is coupled to the cylindrical portion is equipped with a pumping means for introducing the water of the outer tank and the washing irradiation into the inside of the washing tank during washing. It is a washing tank of a fully automatic washing machine.

Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 2 to 4.

FIG. 2 is a longitudinal sectional view showing a washing machine in which the present invention is installed, FIG. 3 is a perspective view showing the washing tank of FIG. 2, and FIG. 4 is a perspective view showing the pumping means of FIG. The inner circumferential surface of the cylindrical portion 2 is formed flat so that the upper and lower flows of the laundry smoothly during washing, and a plurality of dehydration holes 3 are formed on the inner circumferential surface of the cylindrical portion 2, and the cylindrical portion ( At the bottom of the base 4 coupled to the lower part of 2), pumping means 6 for introducing water between the outer tub 5 and the washing tub 1 into the washing tub 1 during washing is provided with the base 4. It is provided to insulate between the hubs 7.

In addition, the pumping means 6 is formed with a cylindrical wall 9 in the circumferential direction on a disc 8 forming an inclined surface from the outside to the inside, and a plurality of wings 10 are radially attached to the disc 8. It is composed.

In the present invention configured as described above, as shown in FIGS. 2 to 4, when laundry is put into the washing tank 1 during washing in a fully automatic washing machine, water is started by a predetermined algorithm, and after predetermined water is supplied by a predetermined level, As the motor 11 mounted at the bottom center of the outer tub 5 is driven, the power of the motor 11 is transmitted to the washing tub 1 through the shaft 12 so that the washing tub 1 rotates forward and backward. Washing begins.

When washing is started, washing water flows in the circumferential direction by a plurality of washing vanes 13 radially installed on the bottom surface of the base 4 in the washing tank 1, wherein the upper and lower portions of the washing tank 1 are The pressure difference occurs due to the flow rate difference (i.e., the flow velocity of the lower portion is faster than the upper portion) and the force acts from the upper portion to the lower portion, and in particular, the inner circumferential surface of the cylindrical portion 2 of the washing tank 10 smoothly moves up and down the laundry. Because it is formed to be flat so that the flow of the laundry smoothly from the top to the bottom is made efficient washing.

In addition, a cylindrical wall 9 is formed in the circumferential direction on the disc 8 which is installed at the lower end of the base 4 to insulate between the base 4 and the hub 7 and forms an inclined surface from the outside to the inside. The water between the outer tub 5 and the washing tub 1 is introduced into the washing tub 1 by the chucking means 6 to which the plurality of wings 10 are radially mounted on the disc 8. Since the internal water level rises from B to B within the water level, the effective space for washing the laundry can be expanded, and the water level of the outer tank 5 drops to C, so that the water overflows out of the outer tank 5. The phenomenon can be prevented.

When the washing stroke is completed in this way, the rinsing and dehydration stroke is performed by a predetermined algorithm, and then washing of the laundry can be completed.

As described above, the present invention, since the inner circumferential surface of the cylindrical portion 2 of the washing tub 1 installed in the fully automatic washing machine is formed without the irregular shape, it is possible to smooth the up and down flow of the laundry during washing, the cylindrical portion Since the pumping means 6 is installed at the bottom of the bottom part 2, the external water flows into the inside of the washing tank 1 to increase the washing effective volume, thereby improving washing performance and preventing water from being scattered. And very useful invention which greatly improved the reliability.
