Description

[Detailed explanation of the idea] (b) Industrial application fields The present invention relates to a washing machine.

(b) Conventional technology Generally, in a washing machine, a rotary blade is disposed at the bottom of the washing tub, and the laundry is agitated by a spiral upward water flow generated by the rotation of the rotary blade. .

However, when the washing tub is large or there is a large amount of laundry, the laundry moves slowly, resulting in poor cleaning power. Therefore, in order to improve this problem, there is a washing machine in which a plurality of rotary blades are disposed inside the washing tub.

A conventional example of this type is shown in Japanese Utility Model Application Publication No. 55-101585, in which two rotary blades 52 and 53 are arranged at the bottom of a washing tub 51, as shown in FIG. By simultaneously rotating these rotary blades 52 and 53 in the same direction, a complex upward water flow is generated in the center of the washing tub 51, and the movement of the laundry becomes active.

However, in the case where the two rotary blades 52 and 53 are arranged side by side at the bottom, the water flow becomes stronger and the laundry moves faster, but basically the water flow generated in the washing tub 51 Since the main flow is upward water flow, the movement of the laundry is the same as that of a washing machine with one rotary blade, and the effect of loosening the laundry cannot be obtained much. Therefore, the cleaning power is reduced, such as the formation of washing spots.

(c) Problems to be solved by the invention This invention aims to improve the cleaning power of washing machines.

(d) Means for solving the problem The present invention rotatably supports a cylindrical body having ribs in an auxiliary chamber formed by protruding the wall surface of the washing tub, and a part of the cylindrical body The cylindrical body is placed in the washing tub, and the cylindrical body is forcibly rotated by a motor.

(E) Effect: In other words, the water flow accompanying the rotation of the cylinder and the cylinder body is added to the water flow accompanying the rotation of the rotor, making the movement of the laundry irregular, which loosens the laundry and loosens the laundry. It is something that becomes more active.

(f) Examples Embodiments of the present invention will be described based on the drawings.

1 is a machine frame of a two-tub type washing machine, 2 is an operation unit installed at the rear upper part of this machine frame 1, 3 is a washing tank installed inside the machine frame 1, 4 is also an outer dewatering tank, and 5 is a A dehydration tank disposed in the outer dehydration tank 4; 6 a dehydration motor for rotating the dehydration tank 5; 7 a rotary blade pivotally supported at the bottom of the washing tub 3; A washing motor 9 is rotated by a washing machine, and a reference numeral 9 is an overflow chamber formed by protruding one corner of the washing tub 3. Also, 10 is an auxiliary chamber formed by protruding another corner of the washing tub 3.

Reference numeral 11 denotes a hollow cylindrical body, from which a large number of ribs 12 integrally protrude in the vertical direction so as to have a gear-shaped cross section. And this cylinder 11
is rotatably supported in the auxiliary chamber 10 so that a portion thereof protrudes into the washing tub 3.

The shaft of the cylindrical body 11 is connected to the drive motor 8 via a bearing 13, a pulley 14, etc., and the cylindrical body 11 is forcibly rotated by the drive motor 8.

The operation will be explained based on the above configuration.

The rotary blades 7 in the washing tub 3 are driven by the drive motor 8.
and the cylindrical body 11 rotate at the same time. As shown in the mechanism shown in FIG. 3, the rotary blades 7 and the cylindrical body 11 rotate in opposite directions. First, the rotary blade 7 functions to rotate and wash the laundry as usual, and the cylindrical body 11 uses its ribs 12 and the water flow generated by the ribs 12 to rub against the laundry and to prevent the rotation of the laundry. By applying acceleration, the movement of the laundry is made more active. Furthermore, since the water flow caused by the cylinder 11 (horizontal rotating water flow) has a different form from the water flow caused by the rotor 7 (spiral rising water flow), both water flows are combined and flow into the washing tub 3.
It works to loosen the laundry by creating a complex water flow inside and changing the movement of the laundry.

In this embodiment, the ribs 12 of the cylindrical body 11 are provided in the vertical direction, but they may be provided in a spiral shape, for example. Push it up. Various other shapes are possible, and the shape of the ribs 12 causes a unique water flow.

Further, the rotary blade 7 and the cylinder body 11 may be alternately rotated, and the cylinder body 11 may be rotated by a dedicated motor.

Next, another embodiment is shown in FIG.

This is a cylinder body 11 with a bottom and an aileron 15 provided inside.If the lid 16 is opened and small items such as thin items are placed inside the cylinder body 11, the cylinder body 11 Since the aileron 15 also rotates with the rotation of
The cylindrical body 11 becomes an auxiliary tank for washing small items.

The rotary blade 7 of the above embodiment has a large diameter conical shape and rotates in a short period and at low speed to suppress cloth entanglement, but the rotation of the cylindrical body 11 further improves the cloth entanglement prevention effect and cleaning efficiency. This will improve the results.

(g) Effects of the invention The present invention provides a washing machine with a rotationally driven cylindrical body on the wall of the washing tub. The water flow that occurs as the washing machine rotates is added, creating a complicated water flow inside the washing tub. Therefore, the cleaning power is improved by suppressing and loosening the cloth tangles in the laundry, and further increasing the movement of the laundry.
