  In Patent Literature 1, the sharpening juice cannot be rapidly moved to the outside through a plurality of intermittent long holes formed at intervals. As a result, the drainage was bad and the rice bran was sometimes smelled. In addition, it is conceivable that the sharpening juice is moved quickly by increasing the number of long holes formed in the colander, but when the number of long holes increases, the strength decreases, and the number of long holes formed also increases. There is a limit and early improvement is required.

  Then, this invention was made in view of such a situation, and makes it a subject to provide the colander and the colander bowl set which can discharge a sharpening juice to the outside quickly.

The monkey according to the present invention is a monkey used for sharpening rice, comprising a circular side wall having an open upper end and a bottom wall closing a lower end of the side wall, and an upper end of the side wall. A large number of slits for discharging water downward from below are formed at intervals in the horizontal direction, and annular reinforcing ribs connecting the side wall portions located between the slits adjacent in the horizontal direction in the horizontal direction are formed in the vertical direction. A plurality of slits are provided at intervals, and the slit is formed to have the same width from the upper end to the lower end of the side wall portion, and the width of the slit is 0.5 to 1.5 mm depending on the size of rice grains. Set to an arbitrary size within the range, the outer surface of the reinforcing rib projects outside the outer surface of the side wall portion, and the inner surface of the portion of the reinforcing rib straddling the slit is larger than the inner surface of the side wall portion. Is also located outside, so that the slit Are connected by the direction, the bottom wall portion is configured in a mountain-type shape becomes higher central portion includes an inner portion located inside and an outer portion located outside of the inner side, the inner portion Is constituted by a wall portion serving as a non-drainage portion, and the outer portion is constituted by a water discharge portion formed by extending the slit radially from the lower end of the side wall portion to the inner portion with the same width. It is characterized by.

According to the present invention, since the slits are connected without interruption by the reinforcing ribs in the vertical direction, for example, the sharpening juice that could not be discharged at the upper part of the slits extends to the lower part of the slits. , It can be quickly moved without any obstacles, and can be discharged from the lower part of the slit where no reinforcing ribs are present, and the sharpening juice can be discharged quickly. In addition, by reinforcing the side wall with a plurality of annular reinforcing ribs, the thickness of the side wall can be reduced, so that the weight can be reduced.
In addition, the sharpening liquid that has accumulated in the shape of a mountain, which has become higher toward the center, smoothly flows down to the outer side, which is lower, and is quickly discharged to the outside from the outer water discharge part that extends radially with the same width. You. In addition, by providing the inner portion including the wall portion serving as the non-drainage portion, the shape retaining strength of the bottom wall portion can be increased.

And an outer portion 5B located outside the portion 5A. The inner portion 5A is constituted by a wall portion (slightly thicker than the thickness of the side wall portion 4) serving as a non-drainage portion, and the outer portion 5B is formed by a slit 6 formed in the side wall portion 4 at a lower end of the side wall portion 4. And a water discharge portion extending radially toward the center from the water discharge portion. The slit 6 of the water discharge part is also formed with the same width (constant width). Thus, by providing the inner portion 5A constituted by the wall portion, the shape retaining strength of the bottom wall portion 5 can be increased. Then, the sharpening liquid accumulated in the shape of a mountain that becomes higher toward the center portion smoothly flows down to the lower outer portion 5B side and radially extends to the outer water discharge portion (a large number of slits 6 of the outer portion 5B). ) Is quickly discharged outside.

  The side wall portion 4 is formed in a constricted shape in which the outer diameter decreases toward the lower end, and the width of the slit 6 is changed from the upper end (one end) of the side wall portion 4 to the inner portion of the water discharge portion of the bottom wall portion 5. It has the same width up to the end (the other end). With this configuration, the area of the slit 6 per unit area can be increased from the upper end of the side wall portion 4 toward the inner end of the bottom wall portion 5 of the water discharge portion. In other words, as shown in FIGS. 2 and 4, the width of all the side wall portions 4A, 4A adjacent to each other across the slit 6 having the same width (constant width) decreases toward the lower side of the side wall portion 4 as shown in FIGS. By making it narrow, the area of the slit 6 per unit area is increased. As described above, since the area of the slit 6 per unit area increases from the upper end of the side wall portion 4 toward the inner end of the bottom wall portion 5 of the water discharge portion, the lower side of the sharpening juice is efficiently discharged. By doing so, the sharpening juice can be discharged to the outside more quickly. The width of the slit 6 is set to 1 mm, but may be set to any size in the range of 0.5 mm to 1.5 mm according to the size of rice grains, for example.

  The colander 2 and the bowl 1 configured as described above are prepared, the colander 2 is housed in the prepared bowl 1, and white rice and water are added thereto, and then the mixture is agitated by hand stirring. After the sharpening, as shown in FIG. 9, the colander 2 is lifted obliquely upward from the bowl 1 and the sharpened juice of the colander 2 is discharged into the bowl 1. After the sharpening juice is discharged to the bowl 1, the bowl 1 is tilted and discharged to the sink. This is repeated a plurality of times to finish the sharpening operation.

  The colander and colander bowl set according to the present invention are not limited to the embodiment, and various modifications can be made without departing from the gist of the present invention.

  In the above embodiment, the outer shape of the colander 2 is circular, but may be elliptical, heart-shaped, polygonal such as a triangle or more depending on the case. In this case, the shape of the bowl 1 may be slightly larger and similar to the shape of the colander 2.

  Further, in the above-described embodiment, the water discharge section is provided in a part of the bottom wall section 5. However, the entire bottom wall section 5 may be constituted by a water discharge section, or may be constituted by a wall section having no water discharge section. May be.

  In the above-described embodiment, the slit 6 is formed so as to extend from the side wall 4 to a part of the bottom wall 5, but may be a slit extending to the lower end of the side wall 4.

  Further, in the above-described embodiment, the bottom wall portion 5 is formed in a mountain shape that becomes higher toward the center, but may be a flat bottom wall portion.

  Further, in the above embodiment, the width of the slit 6 is set to be the same at any position in the longitudinal direction, so that the width of the unit is increased from the upper end of the side wall 4 toward the inner end of the bottom wall 5 of the water discharge unit. Although the area of the slit 6 per area is increased, the width of the slit 6 is made wider toward the lower end side of the side wall 4 so that the slit 6 per unit area at the lower end where water is easily discharged is provided.
