- the laser includes two raised portions 101a and 101b formed with the rotation axis P of the pulsator 100 interposed therebetween, and two valleys B 102a and 102b formed between the raised portions 101.
- the protruding portion 101 has a shape that gradually protrudes in the outer circumferential direction from the rotation axis P.
- a cross-sectional shape at a position separated by a predetermined distance L1 from the rotation axis P is developed, the surface of the pulsator 100 (C) As shown in the figure, it gradually rises from valley 102a to ridge 101a, gradually descends from ridge 101a to valley 102b, and gradually rises again from valley 102b.
- it has a wave shape that reaches the raised portion 101b, and then gradually descends again from the raised portion 101b to the valley portion 102a.

Accordingly, the curved surface of the waveform constituting the upper surface of the pulsator 100 is arranged almost continuously on the inner wall surface of the rotary tank 40.
- a ring-shaped edge 44 is left on the outer periphery of the bottom of the rotary tub 40, and the inside of the edge 44 is The pulsator 100 is arranged in the pulsator receiver 45.
- the pulsator 100 for example, clothing existing near the rotation axis P of the pulsator 100 moves outward from the vicinity of the rotation axis P due to the centrifugal force generated by the rotation of the pulsator 100.
- the clothing present on the pulsator 100 moves on the corrugated surface formed by the ridges 101 and the valleys 102 of the pulsator 100. That is, the garment tries to stop at that position due to the inertial force, and moves while sliding on the undulating surface of the pulsator 100.

- the difference (step) L2 between the raised portion 101 and the valley portion 102 constituting the surface of the waveform of the pulsator 100 becomes smaller as it goes closer to the outer periphery in the vicinity of the rotation axis P. Therefore, looking at the vertical movement of the garment moving from the center of the pulsator 100 to the outer periphery due to the centrifugal force, the upward and downward movement gradually increases as the garment moves from the rotation axis P to the outer periphery.
- the clothing that increases the up-and-down movement moves due to the inner ring difference (difference between the circumference of the rotation axis P and the circumference of the outer circumference (speed difference)), that is, the clothing moves with the motion of reversing the clothing.
- the clothing that has reached the outer periphery rises on the inner wall surface of the rotating tub 40 by another clothing sent one after another, and moves again to the vicinity of the rotation axis P.

- FIGS. 2A and 2B are schematic diagrams of the operation principle according to this embodiment, in which FIG. 2A is a perspective view in section of a rotating tub, and FIG. 2B is a graph showing a vibration operation of clothing.
- ridges 101 and valleys 102 formed on the upper surface of pulsator 100 are alternately arranged at equal intervals.
- the folded portions (ridges) of the ridges 101 and the valleys 102 are shown by straight lines for easy understanding.
- the ridge 101 and the valley 102 are symmetrical with respect to the rotation axis P, so that even when the pulsator 100 is rotated at a high speed, the rotation axis does not move.
- the upper surface of the disk is turned up from a line (valley) passing through the rotation axis P, and a flat inclined surface gradually rising toward both sides.
- the two semicircular surfaces forming the upper surface of the pulsator 100 have a shape that is folded back in a V-shape.
- the protruding portion 101 has a shape that gradually protrudes from the rotation axis P in the outer circumferential direction
- the valley portion 102 has a shape that extends substantially horizontally from the rotation axis P to the outer circumference.
- the valleys 102 are illustrated at an acute angle in the drawing, but are continuous with small rounds or flat surfaces.
- the valley 102 may have a shape that is gradually raised in the outer circumferential direction of the force formed horizontally. What is important here is the step L2 between the ridge 101 and the valley 102 at a point equidistant from the rotation axis P.
- the washing power is improved by vibrating the clothes up and down by the rotation of the pulsator 100, so that the level difference L2 substantially becomes the vibration width L2 of the clothes.
- the upper surface of the pulsator 100 is formed of a curved surface having a waveform that gradually increases the amplitude width L2 from the rotation axis P toward the outer periphery.
- the vertical movement of the laundry is expressed as the inclination. It increased in proportion to the inclination angle of the surface, peaked at a certain angle, and decreased after that. From this, it was found that there was an optimum tilt angle. This is because if the inclination angle is too large, the laundry will be pushed by the inclined surface, making it difficult for the laundry to slip on the pulsator surface, and making it difficult to move above the inclined surface.
- the inclination angle ⁇ is preferably 15 to 25 °, and the height difference of the inclined surface is about 0.13 to 0.22 times the pulsator diameter.

Since the clothing near the rotation axis P becomes empty due to the movement of the clothing, the next clothing is supplied near the rotation axis P from above. Clothes that have moved to the outer periphery first will be And rises along the inner wall. Then, the raised garment is sent out to the vicinity of the upper rotation axis P and further descends along the rotation axis P. Thus, the clothing circulates by the rotation of the pulsator 100.
- the major feature of this embodiment is that, in the process of moving from the rotation axis P of the pulsator 100 in the outer peripheral direction, the garment force existing on the pulsator 100 and the bulge 101 and the valley 102 of the pulsator 100 The point is that the amplitude in the vertical direction gradually increases by sliding while moving on the surface of the waveform formed by. That is, the garment located on the surface of the pulsator 100 tries to stop at that position due to the inertial force, and moves while sliding on the undulating surface of the pulsator 100. Looking up and down, clothing moves up and down along the shape of the waveform.
- step L2 the difference between the raised portion 101 and the valley portion 102 (step L2) increases nearer the rotation axis P and becomes smaller toward the outer periphery. Therefore, looking at the vertical movement of the clothing moving from the rotation axis P of the pulsator 100 to the outer circumference due to the centrifugal force, the vertical movement gradually increases as the clothing moves from the rotation axis to the outer circumference.
- FIG. (B) schematically shows the movement of the garment in which the amplitude width L2 in the vertical direction is gradually increased.
- the X axis shows the distance from the center position
- the Y axis shows the upper and lower amplitude width L2 (height) of the clothing.

- the clothing that has reached the position rises along the inner wall surface of the rotating tub 40, and repeats a circulation cycle reaching the vicinity of the rotation axis P again.
- the clothing that increases this vertical movement moves with the rotational motion, that is, the motion of reversing the clothing, due to the inner ring difference between the outer circumference and the inner circumference. Therefore, the clothes circulating in the rotating tub 40 repeatedly perform the washing in which the up-and-down movement is gradually increased while being inverted, so that the same effect can be obtained as in the case of performing the tap washing.

- the clothes change on the pulsator while the clothes rotate in the rotation direction.
- the clothes were uniformly spread on the pulsator, and the twisting of the clothes occurred due to the difference in the rotation speed between the inner circumference and the outer circumference. Therefore, in the conventional pulsator, the clothes tend to be in the shape of a dumpling, and fabric entanglement tends to occur. Moreover, due to the twisting phenomenon, problems remain in wrinkling, drying finish, drying time, and the like.
- the problem of the conventional example can be reduced by the movement of the garment in the same manner as in the above-described washing. That is, in this embodiment, Since the upper surface of the lucator 110 is formed as a gently continuous smooth surface, the rotation of the pulsator 110 causes the centrifugal force to cause the clothes to slide on the pulsator 110 toward the outer periphery as shown in B-1. Move.

Repeat the cycle leading to. Since the garment is appropriately inverted due to the difference in speed between the inside and the outside, the fabric is not easily entangled, and twisting and wrinkling hardly occur. In addition, the clothing is loosened by the vertical vibration, and warm air can easily enter into the gap, so that the drying time S can be reduced.
