[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a ball for polishing a rice.

[0002]

[Problems to be solved by the device]

 In the conventional rice-polishing ball, a large number of drainage holes are provided on one side above the peripheral wall portion of the ball body, and water is discharged from this drainage hole after polishing the rice. However, when the water flows upward from the drainage hole during this drainage, the rice that has been sharpened is also guided and is discharged along with the water over the upper end of the ball. This is because the ball surface, which has a large number of drain holes, and the other ball surface are formed in the same plane, so that when the water is drained, the sharpened rice crosses the hole surface and slips toward the upper end of the ball. to cause.

An object of the present invention is to prevent the polished rice from being guided to the hole surface of the ball by sliding with water as described above, and to suppress the discharge of the polished rice.

[0004]

[Means for Solving the Problems]

 According to the first aspect of the present invention, a large number of drainage holes are formed on one side of the peripheral wall portion of the ball body, and the recessed portions are formed by outwardly projecting the inside of the drainage holes or the vicinity thereof. The rice stays in the recess and does not flow out together with the water.

Further, in the invention of claim 2, since the recess is formed inside the outermost drainage hole, the outermost drainage hole is formed in an L shape in cross section, It is easier to get rid of the water and is more restrained from being discharged to the outside of the ball with water.

Further, according to the invention of claim 3, the recessed portion is formed inside the draining holes leaving one or several rows including the outermost periphery of the draining holes. The holes on the outer side of the outer peripheral drainage holes promote drainage, and the drainers formed in the recesses inside the outermost peripheral drainage holes can catch rice to promote retention.

Further, in the invention of claim 4, since the concave portion is formed in a deep taper shape on the upper end edge side, although the polished rice flows smoothly into the concave portion along the tapered surface. Since the upper edge of the recess is formed high, the rice that has been ground remains in the recess and does not flow out of the ball.

【Example】

 Hereinafter, a sharpened rice ball of the present invention will be described with reference to the accompanying drawings. 1 to 4 show a first embodiment of the present invention, in which 1 is a bottomed ball having an opening on the top surface, and the ball 1 gradually expands from the bottom to the opening on the top surface. It has a mortar-shaped peripheral wall portion 2, and a large number of drainage holes 3 are formed on one side of the peripheral wall portion 2 and upward. Then, the inside of the outer peripheral edge of the large number of drainage holes 3 is projected outward from the peripheral wall portion 2 by about 2 to 3 mm to form a concave portion 4 in which rice R is accumulated.

In the present invention configured as described above, rice R is put in the ball 1, and when the rice R is finished to be ground, the water is drained by tilting the ball 1 with the drain hole 3 facing downward. However, at this time, the water after polishing the rice R is drained from the large number of drain holes 3 formed in the peripheral wall portion 2, and at the same time, the rice R also follows the water and flows out along the inner surface of the peripheral wall portion 2. However, by forming the drainage holes 3 in the recessed portion 4, the polished rice R is also collected in the recessed portion 4 and stays in the recessed portion 4 due to the step of the recessed portion 4, so that the polished rice R is Only water does not flow from the upper edge of the ball 1 and is drained from the drain hole 3.

Therefore, the polished rice R stays in the recess 4 without flowing out of the ball 1 together with the water, and the rice R can be ground very efficiently.

FIG. 5 and FIG. 6 show a second embodiment of the present invention. The parts having the same functions as those of the first embodiment are designated by the same reference numerals, and the description of the overlapping parts will be omitted. .

In the above-described embodiment, an example in which the outer peripheral edge portion of the drainage hole 3 is projected to form all the drainage holes 3 in the concave portion 4, but in this embodiment, the outermost drainage hole 3A is recessed. It is formed at the base end of the recess 4.

That is, in the present embodiment, the outermost drainage hole 3A has an L-shaped cross section as shown in the cross-sectional view of FIG. 5 by projecting the concave portion 4 from the central portion of the outermost drainage hole 3A. The peripheral edge portion of the recessed portion 4 that retains the rice R that has been sharpened and has been sharpened is made uneven by the drainage holes 3 and the rice R is reliably caught, and the effect of suppressing the rice R can be further enhanced. .

FIG. 7 shows a third embodiment of the present invention. The parts having the same functions as those of the first and second embodiments are designated by the same reference numerals, and the description of the overlapping parts will be omitted.

In the present embodiment, the drainage holes 3A from the second row are formed in the depression 4 while leaving the outermost drainage holes 3A in one row.

Therefore, in the present embodiment, the outermost drainage hole 3A is formed in the peripheral wall surface 2 of the ball 1, and the recessed portion 4 is formed in the drainage holes 3 in the second and subsequent rows other than the outermost drainage hole 3A. The rice R can be retained in the water 4 and the water can be satisfactorily drained by the water draining hole 3A formed in the outer contour of the depression 4 in which the rice R is accumulated.

FIG. 8 shows a fourth embodiment of the present invention. The parts having the same functions as those of the above-mentioned embodiments are designated by the same reference numerals, and the description of the overlapping parts will be omitted.

In each of the above-mentioned embodiments, the recessed portion 4 for storing the rice R is formed with a uniform depth, but in this embodiment, the recessed portion 4A has a tapered shape in which the lower end side is shallow and the upper end edge side is deep. Is formed.

That is, in the present embodiment, the polished rice R smoothly flows into the recess 4A along the tapered surface of the recess 4A, but since the upper edge of the recess 4A is formed high, Rice R introduced into the portion 4A stays well in the recess 4A and does not flow out of the bowl.

Although the embodiments of the present invention have been described in detail above, the present invention is not limited to the above-mentioned embodiments, but various modifications can be made within the scope of the present invention. For example, the number and shape of the drain holes or the overall shape of the ball 1 may be set appropriately. In addition, in the third embodiment of the present invention, an example is shown in which the outermost periphery of the drainage hole is left in one row to form the recess, but one or more rows may be left to form the recess. In addition, if a protruding portion is formed so as to project inward on the upper edge side of the recessed portion, the rice that has been ground can be retained in the recessed portion more effectively.
