Description

TECHNICAL FIELD The present invention relates to a rice-cooking auxiliary container that is installed in a rice-cooking container and used.

A rice cooker provided with an inner pot and an outer pot has been proposed. A large number of through holes are formed in the inner pot so that water can pass through the through holes. The inner pot can be moved up and down by an elevating device, and by raising the inner pot, the inner pot is separated from the water while leaving the water in the outer pot (see, for example, Patent Document 1).

When this rice cooker is used to cook rice, the water containing sugar is separated from the rice by raising the inner pot during cooking. By continuing to cook rice in this state, part of the saccharides can be discharged from the inner pot and received by the outer pot. As a result, it is possible to obtain rice from which part of the sugar has been cut.

Utility Model Registration No. 3220558

However, the rice cooker itself has a complicated structure, and the inner pot must be controlled to move up and down in order to cut sugar, resulting in high cost. In addition, since the rice cannot be cooked using an existing rice cooker or earthenware pot, the convenience is inferior.

The present invention has been made in view of the above circumstances, and an auxiliary container for rice cooking that can easily remove part of the sugar even when rice is cooked using an existing rice cooker or earthenware pot. intended to provide

The auxiliary container for rice cooking to achieve the above purpose is
When rice and water are placed in a rice cooking container and the rice is cooked by heating with the rice cooking container covered, the rice is stored in the rice cooking container and used, and the rice dissolves into the water when the rice is cooked. An auxiliary rice-cooking container that collects part of the sugar,
a dish portion having a constant depth opening upward and having a storage portion inside thereof for storing hot water boiled during rice cooking;
A protruding portion provided on the outer peripheral portion of the upper end of the plate portion, protruding to the outer peripheral side above the storage portion , placed on the upper end of the rice cooking container, and sandwiched between the upper end of the rice cooking container and the lid. and,
with
The outer peripheral side and the inner peripheral side of the rice-cooking auxiliary container are communicated with each other on the peripheral surface of the plate portion , and the hot water that has boiled and moved upward in the rice-cooking container is transferred to the outer peripheral side of the rice-cooking auxiliary container. A communication path is provided to guide from to the storage unit,
The storage portion is formed in a region below the lower end of the communication passage inside the plate portion,
The peripheral surface is inclined so that the plate portion narrows downward,
The communication path is characterized by having a shape that widens from the lower end toward the upper end so that the width of the lower end is the narrowest and the width of the upper end is the widest.

By placing the projecting portion of the auxiliary rice-cooking container on the upper end of the rice-cooking container such as a pot, the storage portion is arranged in the rice-cooking container. When rice is cooked in this state, boiling hot water is blown out to the top of the rice cooking container, and the hot water is guided to the reservoir through the communication passage, and a certain amount of hot water is stored in the reservoir. Since the hot water contains sugar dissolved from the rice, it is possible to cut some of the sugar in the rice.

Further, when rice is cooked, boiling water imparts a force to move the rice cooking auxiliary container. If the rice-cooking auxiliary container is overturned by the force, the hot water stored in the reservoir will be returned to the rice. In this regard, since the projecting portion is sandwiched between the rice cooking container and the lid, the rice cooking auxiliary container can be stabilized in a state in which the opening of the storage portion faces upward. As a result, it is possible to reduce the possibility that the hot water once stored in the storage part is returned to the bottom side of the rice cooking container.

Therefore, even when rice is cooked using an existing rice cooker, clay pot, or the like, part of the sugar can be easily removed.

In addition, since the plate part is shaped to narrow downward, the communication path provided on the peripheral surface can be inclined, and the hot water moving upward in the rice cooking container can be well guided to the communication path. can be done. Furthermore, in the communication path, the width of the lower end is the narrowest and the width of the upper end is the widest, so that the hot water once stored in the reservoir can be used to cook rice. It is possible to suitably take the hot water boiled in the rice cooking container into the communication passage while reducing the possibility of returning from the rice cooking auxiliary container to the rice cooking container.

The figure which shows the other example of the auxiliary container for rice cooking.

An embodiment embodying a rice cooking auxiliary container according to the present invention will be described below with reference to FIGS. 1 to 3. FIG.

<Overview of rice cooking auxiliary container 10>
First, the rice-cooking auxiliary container 10 according to the present embodiment will be schematically described. The rice-cooking auxiliary container 10 is used when rice is cooked. In the present embodiment, a case where an earthenware pot 11 is used as a rice-cooking appliance will be described as an example.

As shown in FIG. 1(a), the rice-cooking auxiliary container 10 is placed above the rice and water before cooking in an earthenware pot 11 for use. The rice-cooking auxiliary container 10 is formed with a through-hole 12 (FIG. 2(a)), and inside the rice-cooking auxiliary container 10, a reservoir 13 (FIG. 3(b)) capable of storing water is provided. )) is provided.

When rice is cooked, a film of starch is formed on the surface of the hot water, impeding evaporation. At that time, when the auxiliary rice-cooking container 10 is set in the earthenware pot 11 , the rising hot water 21 flows into the auxiliary rice-cooking container 10 through the through holes 12 . Since the hot water 22 that has flowed in contains carbohydrates dissolved from the rice 23 , the carbohydrates are separated from the rice 23 by storing the hot water 22 in the storage unit 13 . As a result, rice with reduced sugar content can be cooked.

<Detailed Configuration of Rice Cooking Auxiliary Container 10>
Next, the rice cooking auxiliary container 10 will be described in detail. As shown in FIG. 2, the rice-cooking auxiliary container 10 has a container-like main body 14 that opens upward. The body portion 14 is formed in a dish shape having a substantially circular shape in a plan view, and has a certain depth.

A bottom portion 15 of the main body portion 14 has a flat plate shape, and a peripheral wall portion 16 extends obliquely upward from the peripheral portion of the bottom portion 15 toward the outside (FIG. 3(b)). That is, the body portion 14 has a shape that widens upward (narrows downward). The outer diameter dimension D1 at the upper end of the main body 14 is set to be smaller than the opening diameter at the upper end of the rice cooking container (earthen pot main body 11a).

The through hole 12 described above is provided in the peripheral wall portion 16 . The through hole 12 is formed so as to pass through the outer peripheral side and the inner peripheral side of the peripheral wall portion 16 , thereby communicating the outside and the inside of the main body portion 14 through the through hole 12 .

As shown in FIG. 2(b), a plurality of through holes 12 are formed along the circumferential direction, and the through holes 12 are arranged at regular intervals. Thereby, even if the flow of the hot water 21 rising in the earthenware pot 11 is uneven, the boiling hot water 21 can be favorably guided to the inside of the rice-cooking auxiliary container 10 . The number of through holes 12 is not limited to four, and may be three or less or five or more. Moreover, the number of through holes 12 does not necessarily have to be plural, and a configuration having only one through hole 12 may be employed.

As shown in FIGS. 2A and 3A, each through-hole 12 is formed in the peripheral wall portion 16 near the upper portion of the main body portion 14. It is formed so as to extend in the vertical direction up to the height position of . The vertical dimension L (FIG. 3B) from the upper end portion 12b (FIG. 3C) of the through hole 12 to the lower end portion 12a is common to each through hole 12. In other words, each through hole The lower end positions of the holes 12 are all at the same height position.

Then, as shown in FIG. 3B, a space having a depth D2 from the lower end of each through-hole 12 to the surface of the bottom portion 15 from the lower end of each through-hole 12 inside the body portion 14 . 17 is the storage part 13 mentioned above. In other words, the volume of the space 17 is an effective volume capable of storing the hot water 21 that has moved upward within the clay pot 11 .

As shown in FIG. 3(c), each through-hole 12 has a generally inverted triangular shape when viewed from the front. That is, the width W1 of the opening of the lower end portion 12a is the smallest, and the shape widens upward. With such a configuration, it is possible to suppress the saccharides separated from the rice 23 from returning to the rice 23 side again. That is, when the amount of hot water in the reservoir 13 increases and the water surface rises, the force of the newly flowing hot water 21 tends to disturb the water surface. In this case, for example, in a structure in which the opening width in the vertical direction of the through holes 12 is constant or a structure in which the opening width increases downward, the hot water 22 in the reservoir 13 may easily flow out from the through holes 12. . In this regard, in the present embodiment, since the opening width of the through hole 12 is narrow at the lower end portion 12a closest to the water surface, it is possible to suitably suppress the hot water 22 from jumping out as described above.

As shown in FIGS. 2A and 3A, a flange portion 18 is provided at the upper end of the peripheral wall portion 16 so as to protrude outward. The flange portion 18 plays a role of supporting the rice cooking auxiliary container 10 in the earthenware pot 11 . Specifically, as shown in FIG. 1(a), when cooking rice, the flange portion 18 is sandwiched between the upper end of the earthenware pot body (rice-cooking container) 11a and the lid portion 11b, and the weight of the lid portion 11b (downward The rice cooking auxiliary container 10 is set so that the flange portion 18 is sandwiched by the pressing force of .

For example, in a configuration in which the auxiliary rice-cooking container is placed on the rice in the earthenware pot body 11a or floated on water without the flange portion 18, the rice-cooking auxiliary container is lifted by the rise of the hot water surface. is overturned, and the saccharides stored in the storage part may return to the rice side again. In this regard, in the present embodiment, since the flange portion 18 is sandwiched between the upper end of the earthenware pot body 11a and the lid portion 11b, the rice cooking auxiliary container 10 is supported in a stable state. This prevents the rice cooking auxiliary container 10 from wobbling or overturning due to the boiling water 21, and prevents the hot water 22 in the reservoir 13 from spilling. In particular, in the present embodiment, since the flange portion 18 is formed over the entire circumferential direction, the rice cooking auxiliary container 10 is supported more strongly during rice cooking, and the rice cooking auxiliary container 10 is supported inside the clay pot 11. You can stabilize your posture.

Here, the body portion 14 (the bottom portion 15 and the peripheral wall portion 16) and the flange portion 18 are integrally formed of heat-resistant silicone resin that can withstand the heat during rice cooking. That is, the flange portion 18 is made of a soft material and is deformable. Therefore, the flange portion 18 functions as a sealing member that seals the upper opening of the earthenware pot main body 11a, and boiling over from the earthenware pot main body 11a can be suppressed. In order for the flange portion 18 to function as a sealing member, the entire body portion 14 including the flange portion 18 does not necessarily need to be flexible, and at least the flange portion 18 should be flexible.

The size of the projection of the flange portion 18 is not particularly limited, and may be large enough to hook the rice-cooking auxiliary container 10 to the upper end of the earthenware pot body 11a. Specifically, the outer diameter of the flange portion 18 may be larger than the diameter of the opening at the upper end of the rice cooking container (earthen pot main body 11a). By increasing the projection dimension of the flange portion 18 (the outer diameter of the flange portion 18), the rice cooking auxiliary container 10 can be used even in a rice cooking container having a large opening diameter, and the application range of the rice cooking auxiliary container 10 can be expanded. can be expanded.

As shown in FIG. 2( b ), a pair of handle portions 19 are provided on the outer peripheral portion of the flange portion 18 so as to face each other in the radial direction of the body portion 14 . These handle portions 19 are formed integrally with the flange portion 18 and made of a deformable soft material.

Each handle portion 19 is formed to protrude outward from the outer peripheral end of the flange portion 18 . Therefore, when the flange portion 18 is sandwiched between the lid portion 11b and the earthenware pot body 11a, at least a portion of each handle portion 19 protrudes outside the earthenware pot 11. As shown in FIG. As a result, when taking out the rice-cooking auxiliary container 10 after rice-cooking, the user's hands holding the handles 19 can be positioned outside the earthenware pot main body 11a. Therefore, the user's hands are prevented from being exposed to the high-temperature steam blown out from the earthenware pot body 11a, and the user's burns and dropping of the rice-cooking auxiliary container 10 can be prevented.

Further, each handle portion 19 extends horizontally from the outer peripheral end of the flange portion 18 , and more specifically, the upper surface thereof is flush with the upper surface of the flange portion 18 . As a result, when the lid portion 11b is placed on the flange portion 18 to close the earthenware pot 11, it is possible to prevent the handle portion 19 from interfering with the lid portion 11b to prevent the lid portion 11b from being properly closed.

Each handle 19 is annular and has a hole 19a large enough to insert a finger. Therefore, when taking out the rice-cooking auxiliary container 10, fingers can be hooked on the handles 19, and the taking-out operation can be easily performed.

Here, in the present embodiment, the handle portion 19 is positioned between the through holes 12 adjacent in the circumferential direction of the main body portion 14 so that the through holes 12 and the handle portions 19 are not aligned in the radial direction. For example, in a configuration in which the through-hole 12 and the handle portion 19 are arranged in the radial direction, the portion of the flange portion 18 where the through-hole 12 is located is weaker than the other portions, so when the handle portion 19 is held, There is a concern that the flange portion 18 may be torn off due to the tensile force of , or the main body portion 14 may be excessively deformed by the tensile force and the weight of the hot water 22 in the storage portion 13, causing the hot water 22 in the storage portion 13 to spill out. . In this regard, in the present embodiment, since the handle portion 19 is provided at a portion where the through hole 12 is not arranged (a portion having a higher strength in the flange portion 18), the flange portion when the rice cooking auxiliary container 10 is lifted 18 and excessive deformation of the body portion 14 can be suitably suppressed.

<About the rice cooking method>
Next, a rice cooking method using the rice cooking auxiliary container 10 will be described with reference to FIGS. 1 and 4. FIG.

When cooking rice, first, as shown in FIG. 4(a), rice 23 and water 24 are placed in the earthenware pot body 11a (first step). The amount of water at that time is made larger than the normal amount used with respect to the amount of rice, considering that part of the water is stored in the storage part 13 of the rice cooking auxiliary container 10 and is not absorbed by the rice. Specifically, the amount of water is obtained by adding the volume of the reservoir 13 to the amount of water when the rice-cooking auxiliary container 10 is not used.

After that, the flange portion 18 of the auxiliary rice-cooking container 10 is placed on the upper end of the earthenware pot main body 11a, and the storage portion 13 of the auxiliary rice-cooking container 10 is arranged in the earthenware pot main body 11a. is set on the upper part of the earthenware pot main body 11a (second step). Next, as shown in FIG. 4(b), the cover portion 11b is placed over the rice-cooking auxiliary container 10, and the flange portion 18 of the rice-cooking auxiliary container 10 is sandwiched between the cover portion 11b and the upper end of the earthenware pot main body 11a ( 3rd step).

Then, the clay pot body 11a is heated to cook the rice 23 (fourth step). After a certain amount of time has passed since the start of cooking, as shown in FIG. Moving.

As already described, in the present embodiment, the main body portion 14 of the rice-cooking auxiliary container 10 has a shape that widens upward (FIG. 3(a)). Therefore, inside the earthenware pot body 11a, as shown in FIG. 1(b), a gap dimension W2 between the inner surface of the earthenware pot body 11a on the side of the body portion 14 is smaller upward and larger downward. In other words, the above-mentioned gap, which serves as a flow path for the boiling water 21, gradually narrows toward the through hole 12 of the rice cooking auxiliary container 10. As shown in FIG. As a result, the boiling water (hot water containing carbohydrates) 21 is easily guided to the through holes 12, and the carbohydrates dissolved from the rice 23 can be efficiently recovered.

After the rice 23 is cooked, the lid portion 11b is removed from above the rice cooking auxiliary container 10, as shown in FIG. 4(c). After that, a finger is hooked on the handle portion 19 to take out the rice cooking auxiliary container 10 from the clay pot 11 while preventing the hot water 22 stored in the storage portion 13 from spilling (fifth step).

According to the present embodiment described in detail above, the following excellent effects can be obtained.

In the rice-cooking auxiliary container 10, a storage portion 13 for storing water that has risen due to boiling during rice cooking; and a through-hole 12 that takes in the rising moisture and guides it to the reservoir 13 .

In this auxiliary rice-cooking container 10, the storage portion 13 is arranged in the earthenware pot body 11a by placing the flange portion 18 on the upper end of the earthenware pot body 11a. When rice is cooked in this state, boiling hot water 21 is blown out to the upper part of the earthenware pot main body 11a, and the hot water 21 is guided to the reservoir 13 through the through hole 12, and a certain amount of hot water 22 is stored in the reservoir 13. be. Since the hot water 22 contains saccharides dissolved from the rice 23, the rice from which some of the saccharides have been removed can be cooked.

Further, when rice is cooked, the boiling water 21 imparts a force to move the rice cooking auxiliary container 10 . When the rice cooking auxiliary container 10 is overturned by the force, the hot water 22 stored in the storage part 13 is returned to the rice 23.例文帳に追加In this regard, since the flange portion 18 is sandwiched between the earthenware pot body 11a and the lid portion 11b, the rice cooking auxiliary container 10 can be stabilized in a state in which the opening of the storage portion 13 faces upward. As a result, it is possible to reduce the possibility that the hot water 22 once stored in the storage part 13 is returned to the bottom side of the earthenware pot main body 11a.

- The body part 14 has a dish shape, the flange part 18 is provided on the outer periphery of the upper end, and the through hole 12 is provided in the upper part of the peripheral surface of the body part 14 . By forming the flange portion 18 and the through hole 12 based on the dish shape, it is possible to prevent the shape and structure of the rice cooking auxiliary container 10 from becoming complicated, and to easily form the rice cooking auxiliary container 10.例文帳に追加Become.

- The body portion 14 has a shape that narrows downward (Fig. 3(a)). As a result, the hot water 21 moving upward in the earthenware pot body 11a can be well guided to the through hole 12 of the rice cooking auxiliary container 10, and the saccharide dissolved out of the rice 23 can be recovered efficiently.

- In the through-hole 12, the opening width W1 of the lower end portion 12a is the smallest and has a shape that widens upward (Fig. 3(c)). As a result, the hot water 22 once stored in the storage part 13 can be less likely to return from the rice cooking auxiliary container 10 to the bottom side of the earthenware pot main body 11a. On the other hand, since the position above the lower end 12a is wider than the lower end 12a, the efficiency of guiding the hot water 21 flowing into the reservoir 13 can be kept high.

- The flange portion 18 is formed over the entire circumference (Fig. 2(b)). In this case, a gap is less likely to form between the upper end of the earthenware pot body 11a and the lid portion 11b, and the sealing effect of the flange portion 18 can be enhanced. As a result, the hot water 21 is less likely to spill out of the earthenware pot main body 11a during rice cooking. In addition, since the flange portion 18 is provided on the entire circumference, the stability of the rice cooking auxiliary container 10 during rice cooking is greatly improved.

- A handle portion 19 is provided on the flange portion 18, and the handle portion 19 is formed so as to protrude from the flange portion 18 to the outer peripheral side (Fig. 2(b)). In this case, the handle portion 19 can protrude from the earthenware pot main body 11a, and it is possible to prevent the user's hands from being exposed to the high temperature caused by the rice cooking.

<Other embodiments>

In this case, the outer diameter dimension D1 of the body portion 14 may be smaller than the opening diameter at the upper end portion of the rice cooking pot (container for rice cooking). Moreover, by increasing the overhanging dimension (width in the radial direction) of the flange portion 18, it is possible to flexibly cope with rice cookers having different diameters to some extent.

When a rice cooker such as an electronic jar is used, the handle portion 19 of the rice cooking auxiliary container 10 may become an obstacle. The handle portion 19 can be deformed according to the shape of (a lid of a rice cooker, an outer container, etc.). Therefore, it is possible to avoid interference with the obstacle or reduce the degree of interference. In this case, at least the handle portion 19 should be made of a deformable soft material.

(3) In the above embodiment, each handle portion 19 is configured to extend in the horizontal direction, but may be configured to extend upward from the bottom portion 15 of the body portion 14, for example. At that time, the height position of the upper end of the handle portion is aligned with the height position of the upper end of the main body portion 14 (the height dimension of the handle portion is equal to the depth dimension of the main body portion 14), or the upper end of the storage portion 13 If it is configured to be lower than the upper end of the body portion 14 within a range that does not lower the lid, it is possible to suppress the interference of the handle portion 19 when the lid is closed. Alternatively, the handle portion may extend upward from the flange portion 18 . Since the rice cooking auxiliary container 10 can be lifted by gripping the flange portion 18, the handle portion 19 may be omitted.

(4) In the above embodiment, each through hole 12 extends downward from the upper end of the peripheral wall portion 16. However, as shown in FIGS. 16 may be provided in the middle position. However, when each through-hole 12 is formed from the upper end portion of the peripheral wall portion 16, the lower end position of each through-hole 12 can be raised. has the advantage of being kept small.

(5) In the above-described embodiment, each through-hole 12 has an inverted triangular shape, and the opening width of the lower end portion 12a is the smallest and the opening width of the upper end portion 12b is the largest. do not have. For example, a circular shape (FIG. 5(b)), a heart shape (FIG. 5(c)), a rectangular shape, a star shape, etc. may be used. Any width smaller than the opening width (for example, the opening width W3 in FIGS. 5B and 5C) may be used. In this case, in the vertical direction of the through-hole 12, the opening width of the lower end portion does not necessarily have to be the smallest, and the opening width may be smaller than that of the lower end portion above the lower end portion.
