Description

[Detailed description of the invention] The superimposed uA is a washing tub with a rotary blade in the center of the 611
Concerning a washing machine that performs @.

Conventionally, in a washing tub that has a rotary blade in the center of the bottom, which also serves as a dehydration tank, during washing, the -transfer is caused by a high interruption of 7001 gJ per minute, creating a water flow, but the -transfer is caused by the ψ center of the washing tub. Because the laundry is in the horizontal direction, it does not move much in the vertical direction, and the same place is Ai4.
Cloths were damaged by rubbing against the rotating rotor blades, and uneven washing also occurred.

The present invention has been made in view of the above problems, and an object thereof is to provide a washing machine that can reduce cloth damage caused by the rotary blade and also reduce uneven washing.

That is, in the present invention, the rotational speed of the rotary blade is relatively low at 250 revolutions per minute or less (instead, the diameter is increased to weaken the friction between the rotary blade and the laundry to reduce fabric damage, and to reduce fabric damage. The rotation of laundry is promoted by pushing the laundry around with rotary blades, and the washing tub is provided with a plurality of vertical baffles from the bottom of its side wall so that the rotating laundry is scrubbed by these baffles. The water flow discharged by the pump action of the back blade is raised by the baffle and then directed towards the center, promoting the up-down, in-out and in-out reversal of the laundry.
<It is baffled to allow scrubbing and reduce uneven washing.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be explained below based on figures showing one embodiment. (1) is a washing tank that also serves as a dehydration tank, and its side 411 is provided with a large number of feng shui water holes (2), and a balance ring (3) filled with liquid is attached to its upper edge.
A rotary blade (4) is provided at the center of the bottom, and a 1° washing tub (1) is provided inside an outer tub (5), and the outer tub (5) is suspended from the top of a horizontal frame (not shown) for vibration isolation. has been done. Outer tank ((
At the bottom of the washing machine, there is a dewatering motor (6) that rotates the washing tub (1) and a washing motor (7) that rotates the rotary blades (4).
is installed.

The rotating JIIt4) has a large diameter and extends to the vicinity of the side wall of the washing tub (1), and is provided with a plurality of blades (8) radially. This blade (8) has a protruding tip (-). A low-height auxiliary blade protrudes between the blades (8) and the blade (8). This rotation 1L14) The washing motor (7) rotates at a relatively low speed of 250 revolutions per minute or less. Also, rotor blades (4
) are provided with back blades (to) in a radial manner, and when the rotor blade (4) rotates, the pumping action of this back blade I causes the liquid between the washing tub (l) and the outer tub (5) to flow. The liquid (which will eventually become the liquid in the washing tank (1)) is provided at the bottom of the washing tank, and is sucked from the water passage hole (2) into the washing tank from between the rotary blade periphery and the washing tank bell. Discharge the liquid. In the eccentric arrangement of the washing tub (11), a plurality of carpet baffles close to the rotary blade periphery are forced inward from the bottom to the middle, and between these baffles is a back blade l. The discharged liquid rises and then heads toward the center of the washing tub.
Arrows in the figure indicate the flow of liquid.

In such a configuration, the rotary blade (4) for storing the laundry
When rotating, the rotary blades rotate relatively slowly and the diameter of the rotary blades is large, so that the washed pieces rotate more sn-sn to rub against the rotary blades. Therefore, the laundry is rubbed and scrubbed by the vertical baffles. In addition, since the water flow discharged by the back printing II (11) rises as described above and then returns to the center, the fcFl material is often exchanged up and down, inside and out, and is rubbed against the baffle. *Sounds.

3 and 4 show other embodiments of the rotor (4),
In place of the auxiliary blades shown in Figure 2 (with grooves I), this groove α attracts the laundry to the rotation, making it easier for the blades to rotate around the inside of the washing tank along with the rotary blades. .

As mentioned above (according to Fukka@), by lowering the -turning force and suppressing the damage to the fabric that occurs when laundry is wrapped in 4 clothes, the diameter of the rotor blade is increased. It promotes the rotation of the laundry, compensates for the decrease in cleaning power due to the decrease in friction with the rotary blades by scrubbing the laundry as it rotates and rubs vertically and against the baffle, and by the pumping action of the back blade. The discharged water flow is raised by the vertical baffle and then directed towards the center, which promotes the alternation of the laundry from top to bottom and inside and out, making it possible to wash the laundry all at once. Although the tank has a large number of dehydration holes (2) on the shoulder wall, it may be possible to have no dehydration holes. do it.
