Problems solved by technology

Therefore, in this case, the laundry tends to be washed unevenly, or more cleaning power is given to the laundry staying on the lower side, which causes cloth damage to the laundry.
[0005] Therefore, in the existing washing machine, by changing the operation time of the pulsator or changing the strength of the water flow generated by the pulsator, for example, when the pulsator rotates to the right direction and to the left direction, the movement of the laundry becomes less. Regular or complex for easy up and down interchange of laundry

change example 1

[0121] The pulsator 26A of this modified example can be used instead of the pulsator 26 of the said embodiment.

[0122] Figure 11 (a) and (b) are the perspective views which looked at the pulsator 26A of the modification 1 from above. Figure 11 (a) shows the form when the pulsator 26A rotates to the left when viewed from above, Figure 11 (b) shows the form when the pulsator 26A rotates clockwise as seen from above. Figure 12 It is a perspective view of the rotation part 310 which comprises the variable mechanism part 300 in Modification 1. As shown in FIG.

[0123] In the pulsator 26A of this modified example, as Figure 11 As shown in (a) and (b), the orientations of the first movable blade portion 200A and the first fixed blade portion 130A are the same as those of the first movable blade portion 200A and the first fixed blade portion 130A in the above embodiment. facing the opposite. In addition, if Figure 12 As shown, in the rotation unit 310 constituting the v...

[0132] Figure 13(a) and (b) are cross-sectional views of the pulsator 26 around the first movable vane portion 200A of Modification 2. FIG.

[0133] In this modification example, if Figure 13 As shown in (a), on the sides of the two arm parts 312 of the rotating part 310 that are in contact with each of the first barrier ribs 116 and each of the second barrier ribs 117, rubber, polyurethane, sponge and other materials are respectively attached. Buffer members 381,382. In addition, in this modification example, if Figure 13 As shown in (b), each of the first barrier ribs 116 and each of the second barrier ribs 117 can also be respectively attached with cushioning materials including rubber, polyurethane, sponge, etc. Members 141,142. The buffer members 381 , 382 , 141 , 142 moderate the impact when each arm portion 312 of the rotating portion 310 comes into contact with the corresponding first barrier rib 116 and second barrier rib 117 . Thereby, the impact sound is red...

Abstract

The present invention provides a washing machine capable of reducing uneven washing and cloth damage and improving washing performance. The pulsator includes: a base; a movable blade protruding from an arrangement surface of the base; a variable mechanism capable of changing a protruding height of the movable blade according to a rotation direction of the pulsator; a drive motor; and a control unit. The variable mechanism part includes: a rotating part rotatable relative to the base part; and a moving cam that moves the movable blade part to a protruding position as the rotating part rotates, and the base part includes a first blocking rib that when the movable blade part moves to The rotating part is in contact with the first barrier rib in the protruding position. The control unit performs rotation start-up control on the drive motor so that the rising section up to the target rotation speed includes the first section and the second section following the first section, and the speed is set to be constant in the first section, and the speed is set to be constant in the first section. The rotating part is in contact with the first barrier rib, and the rotating part is integrally rotated with the base part.

Description

technical field [0001] The invention relates to a washing machine. Background technique [0002] Conventionally, a so-called scroll type washing machine has a pulsator rotatably provided at the bottom of the washing and dehydrating tub. The rotation of the pulsator generates a water flow in the washing and dehydrating tub, and the laundry is stirred by the water flow. In addition, the laundry is agitated or rubbed by the pulsator itself in contact with the laundry. In this way, washing is carried out in the washing and dehydrating tub. During washing, the pulsator repeatedly rotates to the right and to the left. [0003] In the lower part of the washing and dehydrating tub close to the pulsator, the laundry is easily subjected to strong water flow and is easily in contact with the pulsator. Therefore, when a lot of laundry is put into the washing and dehydrating tub, the laundry on the lower side is easily washed and the laundry on the upper side is not easily washed. ...
