Description

  The present invention relates to a structure of a measuring cup for measuring the amount of rice cooking raw material such as rice cooked with a rice cooker.

  Conventionally, there are measuring cups for measuring rice to be cooked with a rice cooker. In this measuring cup, place the measuring cup in the rice bottle and scoop up the rice, and the rice protruding from the upper end of the measuring cup is almost flat (horizontally) aligned with the upper end without shaking the measuring cup. It is used to measure the amount of rice that you want to cook. At the time of cooking, if the ratio of the amount of rice and the amount of water changes, the quality of rice at the time of cooking will change greatly. Therefore, it is necessary to accurately measure the amount of rice during cooking. In Patent Document 1, one rice is weighed by scraping the rice at the upper end of the measuring cup.

  Recently, an increasing number of users cook rice by adjusting the amount of rice in 0.5 go units (for example, 0.5 go, 1.5 go, 2.5 go ...). If you want to adjust the amount of rice by 0.5 unit using the above measuring cup, measure the amount of rice by the scale, or measure or cup with the 0.5 unit scale printed or engraved on it. Is used to measure the amount of rice.

JP 2011-106865 A

  In measuring cups such as those described above, when measuring rice cooking ingredients such as 0.5-price rice, the rice cooking ingredients cannot be scraped off according to the upper end of the measuring cup. There was no choice but to set the scale. In order to adjust to the graduation line of the measuring cup, the rice cooking material scooped up more than the amount to be measured is gradually spilled out of the measuring cup by tilting the measuring cup, and the amount is adjusted. At that time, there was a problem that the user tilted the measuring cup too much and spilled the rice cooking raw material too much, and the rice cooking raw material had to be scooped again.

  The present invention has been made to solve the above-described problems, and provides a measuring cup that can easily adjust rice cooking raw materials such as rice even when the measuring cup is not fully cut. For the purpose.

  The measuring cup according to the present invention includes a measuring portion that closes one end of a cylindrical body and uses the other end as an open portion, an opening surface that is a plane formed by the opening, and the opening. A center axis that is a straight line passing through the center of gravity of the shape of the opening when viewed from the direction perpendicular to the surface and the center of gravity of the shape of the bottom when viewed from the direction perpendicular to the bottom. The surface is inclined with respect to the central axis, and the bottom is formed in parallel with the opening surface.

  According to the present invention, the opening is inclined with respect to the cylinder, and the rice cooking material inside the measuring cup is spilled from the point where the angle formed by the plane formed by the opening end surface and the cylinder is the largest. The amount of spilled rice cooking material with respect to the angle at which the measuring cup is tilted is reduced, and the adjustment of the cooking rice cooking material to be measured becomes easy.

Embodiment 1 FIG.
FIG. 1 is a perspective view showing a measuring cup 100 according to Embodiment 1 of the present invention. FIG. 2 is an explanatory view showing an AA cross section of the measuring cup 100 of FIG.
The measuring cup 100 in the first embodiment includes a measuring unit 10. The measuring unit 10 includes a cylinder 11 and a bottom 14 that closes one end of the cylinder 11. An end of the cylinder 11 on the opened side is an opening 15 of the measuring unit 10. The opening 15 and the bottom 14 are parallel to each other. More specifically, the opening surface 21 which is a virtual plane formed by the opening 15 is parallel to the bottom 14. Moreover, the opening surface 21 is parallel to the bottom surface 13 which is a surface in the measuring unit 10 of the bottom portion 14. However, the bottom surface 13 may be a curved surface protruding upward in FIG. In that case, the opening surface 21 and the plane including the curve 17 formed by the bottom surface 13 and the inner peripheral surface 16 of the cylindrical body 11 intersect with each other are formed in parallel.

  In the first embodiment, the cylindrical body 11 has an elliptical cross section parallel to the opening 15. Further, the cylindrical body 11 is inclined with respect to the opening surface 21. That is, the central axis 22 of the cylinder 11 is inclined with respect to the normal line 23 of the opening surface 21. As shown in FIG. 2, in the first embodiment, the cylindrical body 11 is configured with the same cross section parallel to the opening 15 from the bottom 14 to the opening 15. You may be comprised so that it may become large gradually as it goes to the opening part 15 from 14. FIG. In addition, the cross section parallel to the opening part 15 of the cylinder 11 does not necessarily need to be elliptical, and can be changed as appropriate. Whatever the cross-sectional shape of the cylindrical body 11, the central axis 22 is defined as follows. The central axis 22 passes through the center of gravity of the shape of the opening 15 when viewed from the direction perpendicular to the opening surface 21, and passes through the center of gravity of the shape of the bottom 14 when viewed from the direction perpendicular to the bottom 14.

  In the first embodiment, the inclination direction of the opening surface 21 with respect to the cylinder 11 is inclined in the direction along the long axis of the ellipse that is the cross-sectional shape of the cylinder 11, but is not limited thereto. What is necessary is just to set the inclination direction of the opening surface 21 with respect to the cylinder 11 suitably in arbitrary directions.

  As shown in FIG. 2, a measuring line 60 is provided on the cylinder 11. The measuring line 60 is formed on the cylindrical body 11 by means such as engraving or printing. The measuring line 60 is oriented in the longitudinal direction from the bottom 14 toward the opening 15 when the bottom 14 is placed horizontally. Here, the arrangement of the measuring lines 60 will be described in detail. A plane including the central axis 22 of the cylindrical body 11 and the normal line 23 of the opening surface 21 is defined as a central surface 20. Two intersections between the center plane and the opening 15 are defined as opening intersections 31 and 32. Two intersections of the curve 17 and the central surface 20 where the inner peripheral surface 16 of the cylindrical body 11 intersects the bottom surface 13 are defined as bottom intersections 33 and 34. A square 26 is formed by connecting the opening intersection points 31 and 32 and the bottom intersection points 33 and 34. In the first embodiment, the quadrangle 26 is represented by a parallelogram, and the shorter diagonal line 24 of the diagonal lines 24 and 25 of the parallelogram is connected to the cylindrical body 11 from the direction perpendicular to the central surface 20. A measuring line 60 is provided along the projected line. Note that the rectangle 26 is not limited to a parallelogram. For example, when the cylinder 11 is formed so that the cross-sectional shape increases from the bottom 14 toward the opening 15, the quadrangle 26 has a trapezoidal shape. Thus, even when the square 26 is trapezoidal, the measurement line 60 may be formed along a line obtained by projecting the shorter diagonal line 24 onto the cylindrical body 11 from the direction perpendicular to the central surface 20.

<Weighing with measuring cup 100>
The measurement of cereals such as rice and wheat, which are rice cooking ingredients using the measuring cup 100 according to the first embodiment, will be described. In the following description, a case where rice is weighed will be described as an example.

  In the first embodiment, in the measuring cup 100, the volume of the measuring unit 10 from the bottom 14 to the opening 15 is set to, for example, 1 unit. However, the volume can be changed as appropriate. The user inserts the measuring cup 100 into the rice stored in the rice bin, and scoops up the rice so that the measuring unit 10 can be accommodated in the rice. When the measuring cup 100 is inserted into the rice, if it is inserted into the rice from the opening intersection 31 side where the cross-sectional shape shown in FIG. 2 is an acute angle, the opening 15 of the measuring cup 100 is easily inserted into the rice. be able to. In addition, since the opening part 15 of the opening part intersection 31 becomes an acute angle, so that the inclination | tilt angle 27 of the opening surface 21 with respect to the central axis 22 of the cylinder 11 becomes large, it becomes easy to insert the measuring cup 100 in a rice.

  When the rice that has been scooped up into the measuring cup 100 at the end of the opening 15 is rubbed into the measuring cup 100, one total amount of rice can be obtained.

  In addition, in order to measure rice in 0.5 unit, which is desired by users in recent years, weigh in the following procedure. First, the measuring cup 100 is inserted into the rice stored in the rice bin, and the rice is sprinkled. At this time, the amount of rice to be sprinkled may be more than half that of the weighing unit 10. Then, the rice is spilled from the opening 15 so that the rice in the weighing unit 10 becomes 0.5 go, that is, half of the volume from the bottom 14 to the opening 15 of the weighing unit 10. When spilling rice from the weighing unit 10, the rice is spilled from the side of the opening intersection 32 that is symmetrical to the opening intersection 31 about the central axis 22 of the cylinder 11. In this way, compared to the measuring cup 101 in which the opening 15 and the bottom 14 are not inclined with respect to the cylindrical body 11, the amount of rice spilled per unit angle for tilting the measuring cup 100 is reduced. Therefore, the user can easily finely adjust the amount of spilled rice, and there is an advantage that the amount of rice contained in the weighing unit 10 can be easily adjusted to the measuring line 60.

  The point that the fine adjustment of the amount of spilled rice in the measuring cup 100 according to Embodiment 1 is facilitated will be described below. The measuring cup 101 in which the opening 15 and the bottom part 14 are not inclined with respect to the cylindrical body 11 will be described as a comparative example in comparison with the measuring cup 100.

  FIG. 3 is an explanatory view schematically showing the measuring cup 100 of FIG. FIG. 4 is an explanatory view schematically showing a measuring cup 101 as a comparative example. 3A is a view of the state in which the opening 15 is horizontal, FIG. 3B is a view of the state in which the opening 15 is inclined by about 40 ° from the state of FIG. 3A, and FIG. It is a figure of the state which 60 inclined about 40 degrees from horizontal. 4A is a view of the state in which the opening 15 is horizontal, FIG. 4B is a view of the state in which the opening 15 is inclined by about 40 ° from the state of FIG. 4A, and FIG. It is a figure of the state which 60 inclined about 40 degrees from horizontal. In addition, in the measuring cup 100 and the measuring cup 101, what represents the same or equivalent part in each drawing shall be displayed with the same reference numeral. In the measuring cup 101, the cross-sectional shape of the cylinder 11 from the bottom 14 to the opening 15 is the same as that of the measuring cup 100, and the bottom 14 and the opening 15 are not inclined with respect to the cylinder 11.

  Consider a case in which the measuring cups 100 and 101 are tilted to spill rice from the state where the rice is filled up to the opening 15 of the measuring unit 10 of the measuring cups 100 and 101. The rice surface 80 accommodated in the measuring unit 10 of the measuring cups 100 and 101 collapses when tilted by about 40 ° from the horizontal, and rice grains begin to flow. Therefore, when the state of (b) in FIG. 3 and (b) in FIG. 4 is reached, the rice grains begin to flow down from the surface 80 of the rice in the measuring cups 100, 101.

  If the measuring cups 100 and 101 are further tilted, and rice grains are further poured, and the rice grains are poured until the surface 80 of the rice meets the measuring line 60, half of the volume of the measuring cups 100 and 101 can be measured. 3 (c) and 4 (c) are views showing a state in which the measuring line 60 of the measuring cups 100, 101 is inclined by about 40 ° with respect to the horizontal, and the rice grains on the surface 80 of the rice at this time are shown in FIG. It flows in the direction of the white arrow in the middle, and finally the surface 80 of rice comes along the measuring line 60.

  FIG. 3C shows a state in which the measuring line 60 of the measuring cup 100 is tilted by about 40 ° with respect to the horizontal, an initial state of the measuring cup 100, and an initial state of the measuring cup 101. It is represented. The angle θ shown in FIG. 3C indicates an angle at which the measuring cup 100 is tilted from the initial state until the measuring line 60 is tilted by about 40 ° with respect to the horizontal. The angle φ shown in FIG. 3C indicates an angle at which the measuring cup 101 is tilted from the initial state until the measuring line 60 is tilted by about 40 ° with respect to the horizontal. According to this figure, it can be seen that the measuring cup 100 has a larger angle for tilting the measuring cups 100, 101 in order to make the rice in the measuring cups 100, 101 half the volume of the measuring unit 10. That is, the relationship of angle θ> angle φ is satisfied.

  Since the measuring cup 100 and the measuring cup 101 have the same volume, the amount of rice grains spilled to halve the rice in the measuring cups 100 and 101 is the same. The amount that the measuring cups 100 and 101 are tilted to spill the same amount of rice is large. The amount of rice grains that spill when the measuring cup 100 and the measuring cup 101 are tilted by the same amount is smaller in the measuring cup 100. That's what it means. That is, it can be said that the measuring cup 100 has a wider adjustment range of the tilting amount of the measuring cup 100 when spilling the same amount of rice than the measuring cup 101, and it can be said that fine adjustment to match the measuring line 60 is easy.

<Effect of Embodiment 1>

Opening intersection points 31 and 32, an intersection line 17 between the inner peripheral surface 16 of the cylindrical body 11 and the bottom surface 13 of the measuring unit 10, and a bottom intersection point 33 and 34 that are two intersection points of the intersection line 17 and the central surface 20 Have. The cylinder 11 includes a measuring line 60. The measuring line 60 is a direction in which the shorter diagonal line 24 of the diagonal lines 24 and 25 of the square 26 formed by connecting the opening intersection points 31 and 32 and the bottom intersection points 33 and 34 is perpendicular to the central surface 20 on the cylinder 11. It is formed along a line formed by projecting from.
By being configured in this manner, the measuring cup 100 can align the surface of the rice cooking raw material inside the measuring unit 10 with the measuring line 60 while tilting and spilling rice from the measuring unit 10. As described in (1) above, the measuring cup 100 can easily adjust the amount of the rice cooking raw material to be spilled.
