The present invention relates to a washing machine, and in particular, a plurality of induction pipes are installed in the rotary bath to guide a part of the washing water to rise during the rotation of the pulsator, the height of the washing water is increased even at low water level or minority It relates to a washing machine to improve the cleaning power and washing efficiency by making it fall.

In general, the washing machine has pre-programmed the washing, rinsing, draining and dehydration strokes in the washing machine control part and allows the user to selectively control the driving of the washing machine so that the laundry can be washed automatically. have.

Such a washing machine is generally as shown in FIG. 1 and is rotatably installed in the water tank 11 and the water tank 11 which are fixedly installed inside the washing machine main body 10 and store a certain amount of washing water required for washing. It is comprised with the pulsator 13 provided in the rotating tank 12 and the inner bottom face of the rotating tank 12, and the drive part 20 which drives the rotating tank 12 and the pulsator 13. As shown in FIG. The driving unit 20 receives the power of the motor 21 and the motor 21 installed in the outer lower side of the water tank 11 and selectively transmits the power to the pulsator 13 or the pulsator 13 and the rotating tank 12. It consists of a clutch 22.

In addition, the guide flow (1) for guiding the washing water is installed by forming only a portion of the section so that the induction is formed in the inside and outside of the rotating tank (12), the upper and lower side of the guide flow (1) is rotated The inflow hole 2 and the drainage hole 3 communicating with the inside of the tank 12 are respectively formed so that the washing water flows into the lower side and is discharged upward when the washing and rinsing administration is performed. At this time, the front filter of the drain hole 3, the mesh filter member 4 is detachably installed to filter foreign matter contained in the wash water drained through the drain hole (3).

In the washing machine configured as described above, when the washing and rinsing stroke, the pulsator 13 receives the forward and reverse rotation of the motor 21 through the clutch 22 and performs the washing and rinsing stroke.

At this time, the forward and reverse pulsator 13 acts as an impeller and forces a part of the wash water into the inlet hole 2 of the guide flow 1, and the wash water introduced through the inlet hole 2 is the guide flow (1). Drained through the volleyball transport (3) on the upper side. This process is repeatedly performed for a pre-programmed time, and the washing and rinsing stroke is performed. At this time, the foreign matter contained in the wash water drained through the drain hole (3) It is filtered from the filter member (4).

In such a washing machine, in particular, the washing and rinsing strokes have an excellent effect by filtering foreign substances contained in the wash water during washing and rinsing administration.

In other words, when washing and rinsing, the pulsator 13 is inverted to form a water stream in the wash water, and the wash water generated in the water flows into the inlet hole 2 of the guide flow 1 formed only at one side of the rotary tub 12. In order to flow in, particularly severe vortex phenomena occurred in the inlet hole (2) site installed in the lower side of the guide flow (1) of the rotary tub (12).

Therefore, when the washing and rinsing administration at the inlet hole 2 side of the guide flow 1 in which the vortices of the wash water are concentrated, the laundry is entangled or twisted.

In addition, since the washing water is not circulated sufficiently, the washing process is performed in a state in which the detergent contained in the washing water is not sufficiently dissolved. Thus, the washing efficiency is lowered and the detergent is naturally drained together with the washing water drained during the draining process. Was a source of waste and environmental pollution.

In addition, the washing water is swirled toward the center by the pulsator 13 is inverted to form a washing water flow.

Therefore, the laundry according to the washing and rinsing administration rotates with the vortex gingival water flow and is exposed to the upper side of the pulsator, that is, the upper side of the center of the rotating tub, so that the laundry is not sufficiently immersed in the washing water, thereby causing a problem of lowering the washing efficiency.

There is a patent application No. 94-21824 which is a prior application of the present applicant to solve the above problems. As shown in FIG. 2, the rotating water tank 12 washes the washing water left by the impeller 40 having a plurality of feathers 41 at the lower side of the pulsator 13 which rotates forward and backward during washing and rinsing stroke. Ascending induction pipe (30) to guide the upper side of the rotating tub 12 is installed in pairs to face each other.

Ascending induction pipe 30 is attached to the inner surface of the rotating tub 12, the rear is opened so as to form a flow path 36 spaced apart from the inner surface of the rotating tub 12, the lower and upper openings, respectively It becomes the inlet 34 and the outlet 35 which wash water flows into. At this time, the outlet 35 is formed to be separated up and down to form the first and second outlets 35b, and a strainer 14 is mounted on the lower outlet 35b to filter out impurities in the wash water. In addition, the first outlet (35a) located in the upper side is formed to be bent inward so that the wash water drained falls like a waterfall to the center of the rotating tub (12).

In this way, a part of the washing water at the time of rotation of the pulsator 13 flows into the inlet 34 and is elevated along the induction pipe 30 so that a part of the rotating tub 12 is curved through the first outlet 35A. Falling to the center of the laundry to beat the laundry to improve the washing performance, the remaining portion is passed through the filter net 14 installed in the second outlet (35b) formed on the lower side to filter the laundry.

As described above, the washing machine pours a part of the washing water toward the center of the rotating tank during the washing and rinsing operation to form a waterfall, and the washing water formed with the waterfall flows on the laundry that rises due to the reversal of the pulsator. There is an advantage of improving the washing efficiency and completely dissolving the detergent by impacting the laundry while the laundry is immersed in the wash water, but the amount of wash water falls like a waterfall, depending on the water level of the wash water changes to low water level or a small number In the above case, it was a weak problem to beat or make a random number. That is, in the case of low water level or minority water, the amount of washing water that is pushed when the pulsator is rotated is smaller than that of the high water level, and the amount of washing water that falls due to the high height to be raised is small, causing the above problem.

Therefore, the present invention is to solve the above-mentioned problems, the object of the present invention is to lower the height of the washing water is raised at low or minor water level to increase the washing performance by dropping a sufficient amount of wash water even at low or minor water position. It is to provide a washing machine that can form a stream of water to prevent the laundry from twisting.
