is shown.

(c) Problems to be solved by the invention In the conventional example, the brushes are provided along the vertical direction of the tank, so the shoes can move within this vertical range. Therefore, a large amount of water was required, and the shoes sometimes floated out of the brush area.

In view of these problems, the present invention provides a washing machine that can wash shoes as well as clothes, and also aims to save water and improve the cleaning effect when washing shoes.

(d) Means for solving the problem The washing machine of the present invention has an aileron removably disposed on the upper part of a rotary vane disposed at the bottom of the washing tub, and on the back side of the aileron. It is equipped with a brush.

(E) Function: When washing clothes, remove the ailerons and
When washing shoes (mainly sneakers), at the same time an aileron is attached to the rotor, the shoes are placed between the rotor and the aileron, and the rotor and the aileron rotate together to scrub the shoes with a brush. wash.

In addition to shoes, you can also wash heavily soiled accessories such as work gloves and socks.

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

In FIGS. 1 to 3, 1 is a washing machine frame, 2 is a washing tub installed inside the machine frame 1, and 3 is installed at the rear of the upper part of the machine frame 1, including various devices such as a timer. The operating section 4, which includes electrical components, is a drive motor, and the rotational force of the drive motor 4 is reduced in speed via pulleys 5, 6 and a belt 7, and is transmitted to the blade shaft 8. A rotary blade 9 is attached to the blade shaft 8. The rotary blade 9 has a large diameter that occupies most of the bottom surface of the washing tub 2, has an upper-shaped shape, and has three blades 10 every 120 degrees along the ridge line. 11 is an overflow filter, and the water level is displayed as high, medium, and low to serve as a guide when washing clothes.

Now, reference numeral 12 denotes an auxiliary blade having a smaller diameter than the rotary blade 9, and has a radial brush group 13 arranged on the lower surface, and a fitting hole 14 in the center that fits into the top of the rotary blade 9. is formed. Further, the upper surface of the aileron wing 12 is sloped downward by C from the center to the peripheral edge. The upper hole edge of the fitting hole 14 provided in the auxiliary wing 13 is threaded, and the top of the rotary wing 9 is also threaded, so that the auxiliary wing 12 can be rotated. Wings 9
After fitting onto the top of the holder, the two are connected using a bolt-type fitting 15. Here, the aileron 12 and the rotary blade 9 are such that during washing, the upper surface of the aileron 12 is located below the low water level surface, and shoes such as sneakers are placed between the aileron 12 and the rotary blade 9. Their heights are adjusted so that they are positioned at a distance D that allows A to fit in.

In such a washing machine, in order to wash shoes, the shoes are placed between the rotary blade 9 and the auxiliary blade 12, and the rotary blade 9, together with the auxiliary blade 12, is rotated left and right at low speed and in a short cycle. let Then, the brush groups 13 of the auxiliary blades 12 and the blades 10 of the rotary blades 9 can scrub strongly.

Furthermore, since the upper surface of the aileron 12 is inclined, even if the shoes are placed on the upper surface of the aileron 12, the small items will fall along the upper surface and be removed from between the aileron 12 and the washing tub 2. It can be quickly guided between the ailerons 12 and the rotary blades 9.

Figures 5 and 6 show the second part of the rotor and ailerons.
This is an example in which the shape of the blades and the connection mechanism between the blades are changed. That is, the rotor blade 16 is
A wing boss 18 in the shape of a triangular prism, which has a planar shape and is connected to the wing shaft 8 at the center and into which the aileron 17 is fitted.
is installed protrudingly.

On the other hand, an outer fitting part 19 is integrally provided on the auxiliary wing 17 from the periphery of an opening 17a provided at the center thereof, and further, the wing boss 18 continues from the end of the outer fitting part 19. An inner fitting part 20 having an inverted U-shaped cross section is formed to be fitted into the inner fitting part 20. A fixing member 21 having a convex cross section from above the opening 17a is attached to the outer surface of the inner fitting part 20 to hold the spring 2.
It is fitted through 2. 23 is the opening 17
a, and the spring 2
A cylindrical portion 23a, into which the protrusion 21a of the fixing member 21 is inserted, is provided to restrict the upward movement of the fixing member 21 biased by the fixing member 21.

Now, several cone-shaped recesses 24 are formed along the peripheral wall of the wing boss 18, and
Holes 25 are formed in the inner fitting portion 20 at positions corresponding to the recesses 24, and the diameters of the holes 25 are gradually reduced from the outside to the inside. Further, recesses 26 are also formed in the inner peripheral wall of the fixing member 21 slightly above the holes 25. Therefore, normally, the outside of the hole 25 is closed by the inner circumferential wall 21b of the fixing member 21.

27 is a sphere disposed within the hole 25, and its diameter is set slightly larger than the inner diameter of the hole 25 and the wall thickness of the inner fitting part 20, so that Normally, a portion of the hole protrudes inward from the hole 25.

In order to attach the auxiliary blade 17 to the rotary blade 16, first, the fixing member 21 is pushed down so that the recesses 26 correspond to the holes 25. Then, the spheres 27 move into the recesses 26 along the inclinations of the inner surfaces of the holes 25, so that the inner fitting portions 20 are fitted into the wing bosses 18 in this state. Then, when the hand is released, the fixing member 21 returns upward due to the bias of the spring 22, so the recess 26 also moves upward, and the spheres 27 are moved to the left by the inner circumferential wall 21b of the fixing member 21. A portion thereof protrudes inward from the hole 25, that is, into the recess 24. In this way, the spheres 27...
4, the ailerons 17 are prevented from coming off upward.

To remove the auxiliary blades 17, the reverse operation may be performed, and by pushing down the fixing member 21, the engagement of the spheres 27 with the recesses 24 is released.

In such an embodiment, the attachment and detachment of the ailerons 17 becomes easier, and the rotary blades 16 to 17 can be easily removed after washing.
It is easy to take out the laundry in between.

FIG. 7 shows a third embodiment, in which when the aileron 28 is installed by increasing the diameter of the aileron 28 or reducing the diameter of the lower area of the washing tub 2, the aileron 28
The peripheral edge of the washing tub 2 is placed close to the inner wall of the washing tub 2 to prevent shoes from entering or exiting. By doing this, the shoes will not fly out above the aileron 28 (outside the brush area) during the cleaning of the shoes. Furthermore, groups of short-haired brushes 29 are provided radially on the upper surface of the aileron 28, so that while washing shoes, lightly soiled shoes, jeans, shirts, etc. can be scrubbed even above the aileron 28. can.

FIG. 8 shows the above-mentioned second embodiment (b in the figure: solid line)
The results of experimentally cleaning shoes using the configurations of Example 3 and Example 3 (C in the figure: dashed-dotted line) are shown, and as is clear from the results, an excellent cleaning ratio can be obtained by using the aileron. I understand. Incidentally, the cleaning ratio is the ratio of the reflectance when light is irradiated to the object to be cleaned before it gets dirty to the reflectance of the object after cleaning, and it is said to be good if it is 1.0 or more or around 1.0. .

Further, the second embodiment and the third embodiment show almost the same cleaning effect, but the second embodiment can guide the shoes on the upper surface of the aileron 17 between the aileron 17 and the rotor 16, while There is a possibility that the shoes may fly out above the ailerons 17, but there is no such concern in the third embodiment. In any case, if you are just washing shoes, the amount of water is sufficient to reach the upper surface of the ailerons, so it is advisable to display this water level line inside the washing tub 2.

Now, if you want to do normal laundry, please use the fourth
As shown in the figure, remove the auxiliary blade 12 and remove the rotary blade 9.
A holding sheet 30 is made of an elastic rubber material and is placed over the top of the laundry during washing to prevent the laundry from lifting up. Further, the presser sheet 30 is
Ribs 31 are provided radially on the lower surface, and since the sheet itself has a rectangular shape that matches the shape of the washing tub 2, the laundry does not rotate along with the water flow, and the laundry rubs against the ribs 31, reducing the degree of cleaning. strengthened.

(g) Effects of the invention The washing machine of the invention is extremely convenient because it has the function of washing shoes in addition to the function of washing ordinary clothes.

Moreover, when cleaning the shoes, the aileron prevents the shoes from floating and scrubs them with a small amount of water, so the cleaning effect on the shoes is good.

Furthermore, instead of shoes, it is possible to wash heavily soiled accessories such as socks and work gloves, making it easy to use.
