Description

Induction pipe of washing machine

The present invention relates to a washing machine, and more particularly, to a rising induction pipe of a washing machine installed on the wall of the washing tank to induce a part of the washing water during rotation of the pulsator and eject it back into the washing tank.

In general, the washing machine has a program of washing, rinsing and draining and dehydrating the washing machine in the washing machine control unit. The washing and rinsing dehydrating stroke is automatically performed by the user's selective driving control.

The conventional washing machine having such a function includes a main body forming an outline, a water tank installed in the main body through a suspension device, and a washing tank rotatably provided in the water tank. And at the bottom of the washing tank is arranged pulsator rotatable forward and backward to form the washing water flow during the washing stroke.

In addition, the lower outer side of the tank is equipped with a motor for generating power, a power transmission device for separately transmitting the power of the motor to a washing tank or a pulsator, and a drain hose disposed in communication with the inside of the washing tank.

Meanwhile, referring to FIGS. 4 and 5, a balancer in which a separate chamber is partitioned so that a constant space is formed in the circumferential direction is formed inside the upper end of the washing tank 10 in which the plurality of dehydration holes 11 are drilled, and the brine is filled in the chamber. (12) is provided. And the wall surface of the washing tank 10 is provided with a rising induction pipe 20 for guiding a part of the washing water to rise in the rotation radius direction when the pulsator (not shown) to the upper side.

A pair of the induction pipe 20 is configured to be attached to the inner wall surface of the washing tank 10 so as to face each other, spaced apart from the inner surface of the washing tank 10 to form a flow path, the lower and upper ends are respectively opened and the wash water flows in. The inlet part 21 and the outlet part 22 which are discharged are comprised. In addition, the outlet 22 is equipped with a strainer 23.

In the conventional washing machine configured as described above, when the laundry and washing water are put into the washing tank 10 and the washing operation is performed, power is applied to the motor so that the pulsator rotates forward and backward. As a result, washing water flow is formed in the washing tank 10, and the laundry is washed by friction with the inner wall of the washing tank 10 and the washing water.

In addition, a part of the washing water that is pushed out in the radial direction by the rotation of the pulsator (not shown) enters the inlet portion 21 of the rising induction pipe 20. Subsequently, the washing water introduced into the inlet part 21 is led upward along the flow path of the induction pipe 20 and is ejected to the center side of the washing tank 10 through the outlet part 22. This jet washing water beats the laundry to improve the washing performance, foreign matter contained in the wash water is filtered by the strainer (23).

However, in the structure of the induction pipe 23 of the conventional washing machine, the amount of washing water rising is considerably lost due to gravity, and thus, there is a disadvantage in that a sufficient amount of the washing water cannot be provided. In addition, since the drop washing water falls only toward the center of the washing tank 10, a strong impact is applied only to the laundry located in the upper center of the washing tank 10, and almost no impact is applied to the laundry located in the inner circumference and the lower space. Therefore, the uniform washing is not made, there is a limit to improving the washing performance.

The present invention is to solve this problem, an object of the present invention is to improve the induction pipe to the inlet to the washing water to be discharged at the same time as the drop from the upper side and the rising induction pipe of the washing machine that can further improve the washing efficiency To provide.

The discharge port is formed so that the washing water is discharged into the washing tank.

In addition, the side flow passage is configured to be inclined upward through guide ribs on both lower sides of the upward flow passage.

Hereinafter, one preferred embodiment according to the present invention will be described in detail with reference to the accompanying drawings. Briefly the accompanying drawings, Figure 1 shows the overall structure of the washing machine according to the invention, Figure 2 and Figure 3 is an exploded perspective view of the washing tank according to the present invention and the back structure of the riser induction pipe is shown.

Washing machine according to the present invention, as shown in Figure 1, the main body 100 of the enclosure shape forming an overall appearance, and a cylindrical water tank 110 is suspended through a plurality of suspension devices in the interior of the main body 100 and In addition, the washing tank 120 is disposed in the water tank 110 so as to be rotatable and has a pulsator 130 at the bottom thereof. In addition, the lower side of the water tank 110 receives the power of the motor 140 and the power of the motor 140 via the belt 160, the washing tank 120 and the pulsator 130 at the same time or pulsator A power transmission device 150 for selectively rotating only the data 130 is installed. Unexplained reference numeral “170” is a drain hose having one end connected to the bottom of the water tank 110 and the other end extending outside the main body 100.

Washing tub 120 is made of a circular shape, the wall surface thereof is provided with a plurality of dehydration holes (120a, see also FIG. 2) and the uneven portion for increasing the friction between the laundry during the laundry administration. In addition, a balance 180 is provided on the inside of the opened upper end of the washing tub 120 to balance the washing tub 120 when washing and dehydrating. In addition, the pulsator 130 receives power from the rotating shaft of the power transmission device 150 to form a washing water flow by forward and reverse rotation during the washing stroke, which is a plurality of radially provided upper blades (130a) and the rising induction described later The lower wing 130b for washing the washing water toward the tube 200 side. Accordingly, the washing water flow is formed when the pulsator 130 rotates, and part of the washing water at the bottom of the washing tank 120 is left in the rotation radius direction by the lower wing 130b.

On the other hand, on the inner wall of the washing tank 120, the induction pipe 200 for guiding the washing water pushed by the lower wing 130b of the pulsator 130 to the upper side and then ejected to the washing tank 120 is composed of a pair Its detailed structure is as follows.

Referring to FIGS. 2 and 3, each of the induction pipes 200 has a flow path formed therein, and a lower end and an upper end thereof are respectively opened so that the inlet 210 through which the wash water flows in and the wash water introduced therefrom. Consists of an outlet portion 220 for guiding the ejection into 120.

The outlet portion 220 of the rising induction pipe 200 is provided with a mesh-shaped strainer 190, to filter foreign matter contained in the washing water sprayed through the outlet portion 220.

And the inlet 210 of the rising induction pipe 200 is the rising flow path 230 for guiding the washing water to the outlet 220 side of the rising induction pipe 200, and guides on both sides of the rising flow path 230 The side flow path 240 branched by the rib 260 is provided. The lateral flow path 240 is formed symmetrically on both lower sides of the upward flow path 230, and is configured to be inclined outward toward the upper direction and has an elongated outlet 250 formed at an upper end thereof. Therefore, the washing water guided upward through the side flow path 240 is discharged back into the washing tank 120. The lateral flow path 240 and the discharge port 250 improves the washing efficiency with the pulsator 130 by using the washing water sprayed to the side as well as the washing water dropped by the rising induction pipe 200 during the washing stroke. To do so. In addition, the side channel 240 is formed to be inclined outwardly so that the washing water is more easily introduced into the side channel 240 when the washing water flow changes due to the forward and reverse rotation of the pulsator 130.

Next will be described the operation and effect of the washing machine induction pipe 200 configured as described above.

First, when a user puts laundry and detergent into the washing tank 120 and operates a washing machine by operating a control unit (not shown), power is applied to the motor 140 after a suitable amount of washing water is supplied. Accordingly, the power transmission device 150 which receives the rotational force of the motor 140 through the belt 160 during the washing stroke again rotates the pulsator 130 forward and backward through the rotation shaft.

Accordingly, the washing water flow is generated by the upper wing 130a of the pulsator 130, whereby the laundry is washed while continuously rubbing the inner wall of the washing tank 120 and the like.

In addition, a part of the washing water is driven in the direction of the rotation radius by the lower wing 130b of the pulsator 130, which is introduced into the rising induction pipe 200 through the inlet 210. A portion of the washing water introduced into the rising induction pipe 200 rises in the vertical direction through the rising passage 230, and the remaining portion of the washing water branches off toward the side passage 240.

The washing water rising through the rising passage 230 falls back into the washing tank 120 through the outlet 220 of the rising induction pipe 200 and collides with the laundry, thereby improving washing performance. In addition, the wash water guided to the side flow path 240 is discharged toward the center from the side wall of the washing tank 120 through the discharge port 250. Due to this, the laundry is three-dimensionally washed by the friction force and washing water flow by the pulsator 130, the lateral jet water flow and the falling water through the greecho rising induction pipe 200.

And when the washing administration is completed, the washing water is discharged through the drain hose 170, the dehydration administration for a predetermined time is in progress. The dehydration stroke is a washing tank 120 and the pulsator 130 is rotated in one direction at a high speed in the state in which the drain hose 170 is opened, the water contained in the laundry is separated by centrifugal force and the water tank through the dehydration hole (120a) Out of the main body 100 through the 110 and the drain hose 170.

Thereafter, after the water is supplied into the water tank 110 again, several rinsing cycles are performed. The rinsing stroke is made up of a similar stroke to the washing stroke and is divided according to the detergent input and the driving time. In addition, when the rinsing cycle is completed, the dehydration stroke proceeds again.

As described above in detail, according to the rising induction pipe of the washing machine according to the present invention, the inlet portion of the rising induction pipe has a rising flow passage for guiding a part of the washing water to the exit side and a side flow passage for guiding the remaining washing water to the side. It is provided to be branched, the discharge port for guiding the discharge of the wash water guided through the side flow path into the washing tank is formed on the upper side of the side flow path. Accordingly, the washing efficiency is more three-dimensionally washed by washing the water through the pulsator's friction force, the washing water flow, and the washing water falling from the outlet through the rising flow path of the rising guide plate, and the washing water through the outlet of the side flow path. There is an improving effect.
