The present invention relates to a roller-type stirrer type washing machine, and in particular, by installing a roller-type stirrer having a roller for generating water flow and rolling motion of the laundry in a dehydration tank, so as to improve cleaning power during large-sized washing, object washing and small-sized washing. One roller type stirrer type washing machine is provided.

Conventional washing machines can be divided into a rotary blade method, a stirring blade method and a semi-wash bath method as shown in FIGS. 10, 11 and 12 according to the type of laundry stirrer.

In the dual rotation method, washing is performed by the flexing effect of the laundry due to the water flow and the frictional contact between the rotary blade 41 of the rotor blade 40 and the laundry. Although good, the damage to the laundry is severe by frequent contact with the rotary blade (41).

And when washing large capacity, the water flow is reduced and the laundry circulation is very poor, so that some parts contacting the rotor blades 41 near the rotor blades 40 are well washed, but the laundry is hardly washed away from the rotor blades 40. The parts that are washed will also be very damaged.

Stirring blade washing method is a rotary blade washing method to raise the rod 52 in the middle of the stirring blade 50, the rotary blade 51 and the rod 52 by the rotational flow and up and down circulation water to smooth the laundry circulation and rotation The mechanical effect between the blade 51 and the rod 52 and the laundry to improve the cleaning effect, but the cleaning effect is smaller than the rotor blade method, and the rod 52 is cumbersome to input and take out the laundry and the rod ( 52) is in the middle, which is disadvantageous for large capacity and object washing.

In the semi-wash tank system, the washing water rotates by the main wall portion 61 and the viscous friction of the semi-wash tank 60, and accordingly, the laundry is rotated together with the main wall portion 71 of the dehydration tank 70 and the laundry at the time of contact friction and reverse rotation. Washing is performed due to the difference in the relative speed between the wash and the wash water, but even during reverse rotation, there is a slight difference in relative speed between the wash and the wash water for a short time until the rotation speed reaches the forward rotation speed. Since only the cleaning effect is small, and in the case of a large capacity, the laundry circulation is not better, so the cleaning effect is further reduced.

As described above, the conventional washing machine has a low washing degree, uneven washing, large capacity washing failure, poor washing of objects (foam, blanket, blanket, etc.), and defects such as damage at small doses.

The present invention was devised to solve the above-mentioned conventional defects, and installed in the dehydration tank with a stirrer having a roller for generating water flow and laundry rolling motion, and having a plurality of washing protrusions on the dehydration tank. With the installation of an auto balancer, it is possible to obtain a uniformly high cleaning effect without foam damage when washing large-capacity and small-capacity laundry, and it is also excellent in washing objects (foams, blankets, blankets, etc.). To provide a roller-type stirrer type washing machine capable of compacting the size of the dehydration tank, the present invention will be described in detail with reference to the attached drawings 1 to 12 as follows.

1 is an overall configuration diagram of a washing machine according to the present invention, the roller-type stirrer type washing machine of the present invention shown therein is a case 1, an outer tub 2 installed inside the case 1, and rotatable therein. Laundry dehydration tank (hereinafter referred to as "dehydration tank") (3), a roller-type stirrer (10) rotatably installed at the bottom thereof, and an auto balancer (20) installed above the dehydration tank (3). And a rotation driving unit 30 for rotating the stirrer 10 and the dehydration tank 3.

The stirrer 10 is at least one roller 14 is condensed between the central journal 12 and the peripheral journal 13 formed in the center of the rotor 11, the roller 14 is cylindrical (□), Conical ( ) Or a spherical shape (?) And various shapes thereof, and a plurality of convex fine washing protrusions 14a may be formed on the surface thereof.

The rotary drive unit 30 is provided with a clutch 33 having a washing shaft 31 and a dehydration shaft 32 in the middle of the outer tub (2) and fixing the motor 34 to one side of the motor pulley (35) And the clutch pulley 36 by a belt 37, the central shaft 12 is coupled to the washing shaft 31 of the clutch 33, the dehydration tank (3) is the bottom surface of the dehydration shaft (32) The washing shaft 31 or the dewatering shaft 32 rotates as the clutch 33 transfers the driving force of the motor 34 by combining the radial reinforcement 3a fixed to the roller agitator 10. Or the dewatering tank 3 is selectively rotated.

In the figure, 4 is an outer tub cover, 3b is an annular protrusion formed on the inner circumferential surface of the dehydration tank 3, 5 is a top cover, 6 is a door, 7 is a drain pipe, and 8 is a drain valve.

Washing machine according to an embodiment of the present invention as described above is different in the washing mechanism during large-sized washing and small capacity washing, and will be described below separately as follows.

First, when washing large-capacity laundry, as shown in FIG. 9, the laundry (C) and the washing water are contained in the dehydration tank (3) and the roller-type stirrer (10) receives the vertical force by the weight of the laundry. Therefore, the roller 14 and the laundry (C) is in direct contact. And when washing the laundry (C) is caught in the roller 14 of the rotating roller stirrer 10, the moving speed is large at the bottom of the rotating and very small at the upper part in contact with the auto balancer 20, which is an auto balancer ( This is caused by contact friction with the washing projection 21 of 20) and the inertia force caused by the weight of the laundry C. In this way, the laundry C does not move and the roller-type stirrer 10 tries to rotate, so the roller 14 of the stirrer 10 performs rolling motion in a direction opposite to the rotational direction of the stirrer 10 by contact frictional force. . At this time, the laundry (C) is subjected to severe flexion due to the contact friction force with the roller (14) and the difference in the transport speed of the laundry (C) in the upper and lower, for example, one point (P) of the laundry (C) is a → b → c → The position changes to d, and rolls around the roller 14 to circulate. And because the moving speed of the laundry (C) is greater than the central part of the outer portion, the cloud (C) cloud phenomenon is also larger than the central part. Therefore, the circulation of the laundry (C), which was active only in the vicinity of the roller (14) of the stirrer (10), gradually spreads to the entire laundry (C) so that the entire laundry (C) circulated well, and the reverse rotation of the stirrer (10) As the laundry (C) stuck to the loosen laundry (C) in the deep coming out and the laundry (C) in the outside into the inside can be obtained uniform and excellent cleaning effect throughout the laundry.

In the case of small-sized laundry, the laundry (C) is pulled out at the time of the forward rotation of the stirrer 16 by the stirrer 14 to form a strong water flow compared to the conventional rotorcraft method, stirring method and semi-wash tank method. The laundry (C) that rotated in the part floats for a short time without being energized by the interaction between the forward and reverse streams when the agitator 10 reverses, and then the laundry (C) is pulled down again as the reverse streams become stronger. Since the laundry (C) circulation up and down occurs, and during the reverse rotation, the laundry (C) is released and circulation occurs inside and outside, that is, to the left and right to obtain a uniform and excellent cleaning effect throughout the laundry (C). It becomes possible.

As described above, the washing machine of the present invention can obtain a uniform and excellent cleaning effect over the entire laundry without damage caused by rolling motion of the roller 14 regardless of the size of the laundry.
