Description

Induction pipe of washing machine

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

In general, the washing machine is configured to program the washing, rinsing, draining and dehydration strokes in advance in the washing machine control unit, and the user can selectively control the washing. The laundry is automatically washed, rinsed, and dehydrated. This is done continuously.

As shown in FIG. 1, the washing machine having such a function is fixedly installed in the housing 10 constituting the exterior body to store a predetermined amount of washing water required for washing, and a plurality of tanks in the tank 20. The washing tank 30 in which the dehydration hole 31 is formed is rotatably provided. And the inner bottom surface of the washing tub 30 is configured to be pulsator 40 that can be rotated forward and backward to form the washing water flow during the washing administration.

The driving unit 50 is configured at the outer lower portion of the water tank 20, and the driving unit 50 transmits the driving force of the motor 51 and the motor 51 which generate power by receiving power through the belt 52. It consists of a power transmission device 53 for driving the washing tank 30 and the pulsator 40. Therefore, the power is selectively transmitted to the pulsator 40 and the washing tank 30 or the pulsator 40 by the rotation shaft 54 of the power transmission device 53 to wash and dehydrate the laundry.

Inside the upper end of the washing tank 30, a separate chamber is partitioned so that a constant space portion is formed in the circumferential direction, and a balancer 60 filled with saline is provided therein. The balancer 60 performs a function of buffering the vibrations and the resulting vibration transmitted to the washing tank 30 side by a wave of salt water during washing and rinsing stroke of the washing machine, and when the washing tank 30 rotates at high speed. The wash tub 30 serves to maintain the balance of the wash tub 30 by attenuating by using the centrifugal force pulled by the balancer 60 relatively to the action to escape to the outside.

The pulsator 40 which performs washing by rotating forward and reverse is formed in a disc shape, and a plurality of radially oriented radially faces the upper surface of the body 43 and the body 43 that are combined with the rotating shaft 54. It is formed of a wing 42 for generating water flow and a laundry rod 41 protruding in the center of the upper surface. And the lower surface of the pulsator 40 body 43 is provided with an impeller 44 made of a plurality of feathers to push the wash water outward.

On the other hand, on the wall surface of the washing tank 30, a rising induction pipe 70 for guiding the washing water left by the impeller 44 at the time of rotation of the pulsator 40 is installed upright. Ascending induction pipe 70 is a pair is attached to the inner wall surface of the washing tank 30, the rear is opened to form a flow path (70a) spaced apart from the inner surface of the washing tank 30, the bottom and top Are each formed of an inlet end 71 into which the washing water is introduced and an outlet end 72 discharged. At this time, the outlet end 72 is curved to the inside of the center of the washing tank 30, so that the discharged washing water falls like a waterfall to the center of the washing tank 30.

In the conventional washing machine configured as described above, when laundry and washing water are put into the washing tank 30 and the washing operation is performed, power is applied to the motor 51 so that the pulsator 40 is rotated forward and backward. Accordingly, the washing water flow is formed in the washing tank 30, and the washing water and the laundry rotate forward and backward together by the friction force between the pulsator 40 and the wing 42, and the inner wall of the washing tank 30 and washing by the washing water flow. Washed by friction with water.

In addition, because the impeller 44 is provided on the lower surface of the pulsator 40 in the forward and reverse rotation, a portion of the wash water is pushed into the inlet end 71 of the rising induction pipe 70 during its rotation. Subsequently, the washing water introduced into the inlet end 71 is led upward along the flow path 70a of the rising induction pipe 70 and is ejected to the center of the washing tank 30 through the curved outlet end 72. This jet washing water beats the laundry to improve the washing performance. This process is repeated for a time programmed in advance in the controller (not shown).

However, in the conventional washing machine, the outlet end 72 of each of the rising induction pipes 70 is curved toward the center of the washing tub 30, and the following problems occur.

That is, according to the forward and reverse rotation of the pulsator 40 provided with the impeller 44, a part of the washing water is introduced through the inlet end 71 of the rising induction pipe 70 and the washing tank 30 again through the outlet end 72. It is ejected to, the outlet end 72 is formed to be curved at the upper end of the induction pipe 70 is ejected only toward the center of the washing tank (30). Accordingly, a strong impact is applied only to the laundry located in the center of the washing tank 30, and almost no impact is applied to the laundry located on the inner circumferential side, thereby preventing uniform washing. Therefore, there is a limitation in improving the washing performance.

The present invention is to solve this problem, an object of the present invention is to provide a rise induction pipe for guiding a portion of the wash water from the lower side to the upper side of the washing tank to fall back to the center of the washing tank, By providing the main outlet and the sub outlet having different heights at the upper end portions, the washing water is uniformly dropped in the entire washing tank to provide a rising induction pipe of the washing machine in which washing performance is improved.
