Description

[Detailed description of the invention] [Technical field of the invention] The present invention is a dehydrating and washing tub that improves the conventional stirring blade installed at the center of the bottom of the inner tub that serves as both a dehydrating tub and a washing tub to prevent damage to laundry. Regarding washing machines.

[Technical background of the invention]

Conventional dehydrating and washing machines are 1/3 to 1/2 of the inner diameter of the inner tub.
A stirring blade with a high protrusion of about 15 mm in diameter was rotated at high speed to create a strong stream of water, which rotated the laundry and carried out the washing action.

[Problems with background technology]

However, since the above-mentioned type generates a strong water flow in the center of the tank, the laundry tends to get twisted, especially when the laundry is small. It had flaws that hurt it.

[Purpose of invention]

This invention was developed with the above points in mind.
The purpose is to provide a dehydrating and washing machine that causes less fabric damage and has high cleaning efficiency.

[Summary of the idea]

This invention rotates a rotating plate that occupies more than 65% of the bottom of the inner tub, and rotates the laundry placed on the rotating plate along with the generated water flow. It is characterized by friction on the uneven striped wall surface, which allows for highly efficient cleaning with less damage to the cloth.

[Example of idea]

Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 1 to 3. 1 is an outer box, 2 is an outer tank that is elastically suspended from the outer box 1 and has a drive transmission mechanism 3 attached to its lower part; 4 is an inner tank that has an annular balance weight 5 fixed to its upper part; A large number of protrusions 4a and drain holes 4b are provided on the inner wall surface to form the same shape, and the bottom surface is provided with a recess for accommodating a rotary plate 7, which will be described later. It is rotatably provided through. 8 is a tank cover, 9 is a top lid with a laundry inlet in the center, 10 is an inner lid, 11 is a motor, 12 is a belt transmission mechanism, 13 is a panel attached to the rear of the outer box, 14 is a timer It is.

Next, the rotating plate 7 will be explained in detail. Rotating plate 7
The outer diameter is approximately the same as the inner diameter of the balance weight 5, and occupies more than 65% of most of the bottom area of the inner tank. The washing shaft 15 has a substantially trapezoidal cross-sectional shape, has a flat or gently sloped surface, and is connected at the center to a washing shaft 15 supported by the drive transmission mechanism 3 with a screw 16. As shown in the sectional view of FIG. 3, several recesses are provided near the outer periphery of the back surface, and a spring 18 and a ball 19 as a rotating body are inserted so as to be elastically supported by the spring 18, and the ball 19 is prevented from coming off. A presser foot 17 is attached so that the ball 19 can rotate.

Next, the operation of the above configuration will be explained. Since the rotary plate 7 occupies most of the bottom area of the inner tub 4, most of the laundry is placed on the rotary plate 7. Therefore, the laundry begins to rotate approximately in synchronization with the rotation of the rotary plate 7. When the laundry floats due to the water flow generated by the rotation of the rotary plate 7 and is no longer in contact with the rotary plate 7, the laundry rotates due to the action of the water flow. When the laundry sinks and is placed on the rotary plate, the laundry is energized by the rotation of the rotary plate 7 and can continue rotating without stagnation. The cleaning action is effectively performed by friction between the laundry and the convex strips 4a on the inner wall of the inner tub 4 as the laundry rotates. Since the rotary plate 7 has a large diameter and most of the laundry is placed on the upper part, the outer peripheral end portion tends to move up and down due to unbalanced load, but if it moves downward, the balls 19 and the bottom of the inner tub 4 will Upon contact, the balls 19 roll and do not damage the bottom of the tank, and the rotary plate 7 can continue to rotate smoothly.

According to the above embodiment, since the rotary plate 7 has a large diameter, the laundry is rotated over the entire area of the tub, so there is less twisting and therefore less damage to the laundry. Moreover, since there is little unevenness in rotation regardless of the magnitude of the load, the cleaning effect can be enhanced. In addition, it has the same performance as conventional products in terms of ease of assembly, serviceability, installation of the rotary plate 7, cleaning of the back surface, etc. That is, by making the rotary plate 7 have approximately the same diameter as the inner diameter of the balance weight 5, it is possible to remove the rotary plate 7 from the tank for inspection work, etc.
The rotary plate 7 can be made as large in diameter as possible while making it easy to reinstall.

[Effect of idea]

As described above, the present invention provides a large-diameter rotary plate in the center of the inner tank, which has approximately the same diameter as the inner diameter of the balance weight and has an area of 65% or more of the bottom surface of the inner tank. Through the synergistic action of the above, it is possible to provide a dehydrating/washing machine that has a high cleaning effect and causes less fabric damage.
