Description

Washing machine provided with roller for mixing the washing water}

The present invention relates to a washing machine, and more particularly, a plurality of rotary rollers interlocked with a pulsator to be installed around the bottom of the washing tank to be incidental to the flow of washing water stagnated at the lower edge of the washing tank when the pulsator is rotated. The present invention relates to a washing machine having a washing water mixing roller which further activates the washing water flow inside the washing tank by generating water flow, thereby ultimately improving washing power and rinsing degree of the laundry.

In general, a washing machine includes a pulsator type using water flow due to the rotation of the pulsator, a rod type using contact with the laundry due to the rotation of the laundry rod, and a drum type using vertical dropping of the laundry due to the rotation of the drum. Type washing machines are the most widely used.

Here, the pulsator type washing machine, as shown in Figure 1, the cabinet 103 to form the outer body, the reservoir 105 is provided inside the cabinet 103 to accommodate a predetermined amount of the washing liquid, A plurality of washing liquid distribution holes 107 are formed at a side thereof, and a washing tank 109 installed inside the water storage tank 105, a pulsator 111 installed at the bottom of the washing tank 109 to generate water flow, and , A driving unit 113 for generating rotational force of the washing tank 109 and the pulsator 111.

The lid 117 is rotatably connected to one side of the opening of the upper panel 115 of the cabinet 103 by a hinge 119, and the operation of the washing machine 101 is controlled inside the upper panel 115. The control unit 121 is built in. In addition, a drain pipe 123 for discharging turbid water after washing is connected to one lower end side of the reservoir 105. And a detergent tank 127 connected to the water supply hose 125 is installed on one side of the upper end of the reservoir 105.

Therefore, the washing machine 101 configured as described above basically washes laundry through the following process. First, the laundry is put into the washing tank 109, and then a suitable amount of detergent is put into the detergent container 127, and when the water source such as a faucet connected to the water supply hose 125 is opened, the detergent container 127 is passed through the water supply valve 131. The water flowing into the) becomes a washing liquid mixed with a detergent and is filled to a predetermined height in the washing tank 109. Then, when the driving unit 113 is operated by the user's operation, the rotation of the pulsator 111 is started and rotational water flow is generated inside the washing tank 109 while repeating the forward and reverse rotation to wash the laundry. After the rinsing and dehydration are complete, all washing is finished.

As such, the washing force of the washing machine 101 originates from the driving unit 113 mounted on the lower portion of the washing machine 101, and the driving unit 113 again rotates the driving shaft 135 of the driving motor 135 and the pulsator 111 to generate the rotational driving force. It is composed of a reduction gear assembly 137 coupled to the transmission belt 139 for transmitting the rotational driving force of the drive motor 135 to the reduction gear assembly 137.

Here, as schematically shown in FIG. 2, the laundry 106 is put into the washing tank 109, the washing water is supplied to the reservoir 105, and then the washing tank is rotated to rotate the washing water and the laundry 106. When the driving unit 113 of the lower end is driven, the pulsator 111 rotates to generate rotational water flow as shown in FIG. 3 inside the washing tank 109.

However, the twisting and tangling phenomenon occurs in the laundry 106 during the operation of the washing machine 101 as described above, because the center rotation occurs at the rotation center of the pulsator 111 during washing as shown in FIG. 3. This is because the rotational direction of the water flow and the peripheral rotational water generated around the lower pulsator 111 of the washing tank 109 are opposite.

As the rotation directions of the central rotational water and the surrounding rotational water are different from each other, the laundry is twisted or tangled with each other near the center of the washing tank, so that the laundry is severely wrinkled or damaged. Furthermore, the impact force caused by the water flow during the washing process There was a problem that the washing power is reduced because the twisted or entangled of the strong portion can not be delivered strongly.

In order to solve this problem, a washing machine 200 in which a water jetting device as disclosed in Korean Utility Model Registration Application No. 98-25074 has been proposed.

As shown in FIG. 4, the washing machine 200 has a suction pipe 211 connected in communication with the bottom side surface at the bottom of the reservoir 201 and a discharge connected in communication with the bottom center at the bottom of the reservoir 201. The pump 215 and the upper end of the discharge pipe 213 to suck the wash water of the reservoir 201 through the pipe 213, the suction pipe 211 and discharge it back to the reservoir 201 through the discharge pipe 213 The water flow ejection device 210 is composed of a nozzle 117 for ejecting the washing water discharged to the upper center of the pulsator 203, characterized in that the laundry tank 102 is filled with laundry When the washing machine 200 is operated in a state in which the water is stored in the water tank 201 by a predetermined amount, the washing process proceeds. At this time, the driving unit 204 and the pump 215 are driven by predetermined control means.

Accordingly, the pulsator 203 once received with the rotational force of the driving unit 204 rotates at the bottom of the washing tank 202 to form a central triangular water flow in the washing water. At the same time, the pump 215 sucks the washing water in the side portion of the lower portion of the water tank 201 through the suction pipe 211, and discharges the sucked washing water through the discharge pipe 213.

At this time, the nozzle 217 installed at the upper end of the discharge pipe 213 discharges the washing water discharged to the upper center through the discharge hole 204 of the pulsator 203, and the water flow discharged in this way is the pulsator 203. Impacting the lower end of the center rotational water flow formed by the) to form a water flow of a uniform shape. That is, the jet stream from the nozzle 217 disperses the lower end of the central rotational flow by the pulsator 203 to suppress the occurrence of peripheral rotational flow according to the central rotational flow, thereby forming a uniform water flow as a whole. .

However, in the case of the washing machine 200 in which the water jetting device is installed, the suction pipe 211 for suctioning the washing water at the bottom of the washing machine for discharging the water flow, and the discharge pipe 213 for ejecting the pressurized water from the center of the washing tank 202. Since a plurality of devices for generating and jetting jetting water flows, such as a pump 215 for circulating jetting water, must be installed, the structure of the washing machine is complicated, and the flow of water is jetted only by the discharge pipe. Because it is limited to not enough to scramble the laundry, there is a problem in that the maintenance cost of the washing machine is increased because additional power is consumed to operate the separate pump 215.

Therefore, the present invention was conceived to solve the problems caused by the tangling of laundry and lowering the washing power of the conventional washing machine as described above, and a plurality of rollers interlocked with the rotation of the pulsator around the pulsator around the bottom of the washing tank. The purpose of the present invention is to provide sufficient kinetic energy to the laundry located outside of the pulsator by rotating the roller together with the pulsator during mounting and washing to improve washing power and rinsing degree of the laundry.

Here, the housing (3) is to form the outer body of the washing machine (1), the water tank (5) is installed inside the housing (3) is supplied through the water supply line (25) and the water supply valve (31) The laundry container is accommodated in the wash water, and the detergent container 27 connected to the water supply valve 31 mixes the detergent and the wash water supplied from the water supply valve 31 to form a washing liquid. And the lower side of the reservoir (5) is connected to the drain pipe 23 for discharging turbidity after the washing is finished, the washing tank (9) installed inside the reservoir (5) to accommodate the laundry loaded The side wall of the washing tub 9 is formed with a plurality of flow holes 7 through which washing water is discharged.

In addition, in the washing machine 1 of the present invention, a plurality of tooth rollers 51 are arranged in the circumferential direction around the pulsator 11 at the bottom edge of the washing tank 9, and the outer circumference of the pulsator 11 is provided. The large diameter serration part 55 which engages with the toothed roller 51 is processed in the edge part.

In addition, each tooth roller 51 may be formed in a cylindrical shape or may be formed in a truncated cone shape so as to more securely engage the large serration portion 55, the rotary pin 59 is fitted along the axis Small diameter serrations are radially arranged on the bottom edge of the washing tank 9 so as to be rotatable, and are engaged with the large-diameter serrations 55 of the outer peripheral edge of the pulsator 11 on the outer circumferential surface of each tooth roller 51. The part 53 is formed.

At this time, in order to mount the toothed roller 51, the bottom surface edge of the washing tank 9 is formed in the circumferential direction of the mounting groove 57 having a cross-sectional shape in the shape of a c as shown in FIG. The mounting groove 57 is inclined by a predetermined angle with respect to the horizontal plane so as to mount the roller roller 51.

Therefore, according to the washing machine 1 according to the present invention having the above configuration, when the laundry is filled in the washing tank 9 and the washing solution in which the detergent is dissolved is stored in the water storage tank 5 in a predetermined amount, washing is started. As the process proceeds, the driving unit 13 is driven according to the driving signal input from the control unit 21.

As the driving unit 13 starts, the pulsator 11 receiving the rotational force rotates forward in the direction of the arrow A, for example, as shown in FIG. 6. At this time, the washing tank 9 by turning the small diameter serration portion 53 of the roller 51 engaged with the large diameter serration portion 55 formed in the inclined state on the outer peripheral edge of the pulsator 11 in the form of a bevel gear.
