  In recent years, it is often preferred to cook using a pot such as a clay pot instead of an electric rice cooker. In order to cook properly, it is considered preferable to efficiently circulate the steam inside the pan. However, since the general cooking container like the said patent document 1 is a hemispherical shape in which the inner surface of a cover body becomes high gradually toward a center part from a peripheral edge, when the vapor | steam inside a pan can always be circulated efficiently. Is hard to say.

  This invention was made paying attention to such a subject, and the objective is to provide the cooking pot which has the shape which can circulate the vapor | steam inside a container appropriately.

  In order to achieve this object, the present invention takes the following measures.

  That is, the rice cooking pan of the present invention comprises a container main body for containing foodstuffs, and a lid body that closes the opening of the container main body, and is provided below the inner surface of the lid body that faces the foodstuffs. A plurality of projections projecting from each other are formed.

  According to this configuration, when the steam is convective along the inner surface of the lid, the steam is diffused by colliding with the protrusion protruding downward, and the steam is not formed as compared with the case where the protrusion is not formed. Circulation can be promoted.

  In order to avoid obstructing the circulation of the steam and appropriately exhibit the effect of promoting the circulation of the steam, the projection is a spherical projection, the diameter thereof is 2 mm or more and 9 mm or less, and the height is 1 It is preferable that it is 5 mm or more and 4 mm or less.

  As a preferred application example of the present invention, the spherical protrusion has a diameter of 5 mm or 6 mm and a height of 2 mm.

  In order to promote the circulation of the steam, an annular ridge is formed on the inner surface of the lid body by raising the peripheral edge upward from the central portion, and the plurality of the ridges are formed on the top surface of the annular ridge. It is preferable that the protrusions are arranged along the circumferential direction.

  In order to be able to cook rice better, it is preferable that the lid and the container body are formed of aluminum cast.

  Since this invention is the structure demonstrated above, a vapor | steam is spread | diffused and it becomes possible to promote the circulation of a vapor | steam. Therefore, it is possible to provide a high-quality cooking pot.

The perspective view which shows the pan for rice cooking which concerns on one Embodiment of this invention. The bottom view which shows a cover body. AA site | part sectional drawing of FIG.

  Hereinafter, a cooking pot according to an embodiment of the present invention will be described with reference to the drawings.

  As shown in FIG. 1, the cooking pot of this embodiment has the container main body 1 for accommodating a foodstuff, and the cover body 2 which obstruct | occludes opening of this container main body.

  The container main body 1 is a pan for holding both hands having a bottomed cylindrical main body 10 and a pair of grips 11 provided on the main body 10. The container body 1 may be made of earth, ceramic, or metal coated with resin. In this embodiment, the container main body 1 and the lid body 2 are formed of aluminum cast. In this way, by forming the main body and the lid body with an aluminum cast excellent in heat conductivity, food (such as rice) can be heated in the whole pan, and rice can be cooked well.

  The lid 2 closes the opening of the container body 1, and a handle 20 is attached to the central portion Ce. As shown in FIG. 2, the handle 20 is screwed into a hole 21 formed in the center of the lid body 2. The lid 2 is made of the same material as the container body 1.

  On the inner surface of the lid body 2, an annular raised portion 22 is formed by the peripheral portion Ri rising upward from the center portion Ce. A part of the annular ridge 22 is formed with vent holes 23 for releasing steam (four in this embodiment). The vent is 4 mm in diameter. Moreover, the inner surface in the center part Ce of the lid body 2 becomes higher from the radially outer side toward the inner side.

  When the container main body 1 is sealed, the inner surface of the lid 2 faces the foodstuff inside. A plurality of projections 3 projecting downward are formed on the inner surface of the lid 2. The protrusion 3 is a spherical protrusion having a diameter of 5 mm or 6 mm and a height of 2 mm. Of course, the shape of the protrusion is not limited to a spherical shape, and various modifications such as a triangle, a quadrangle, and an ellipse can be made. Further, the size of the protrusion can be variously changed, but the diameter is preferably 2 mm or more and 9 mm or less, and the height is preferably 1.5 mm or more and 4 mm or less. If it is smaller or lower than the above, the effect of promoting the circulation of steam cannot be sufficiently exerted, and conversely if it is larger or higher than the above, there is a possibility of inhibiting the circulation of steam, so the above range is appropriate. .

  The plurality of protrusions 3 are arranged along the circumferential direction on the top surface 22a of the annular ridge portion 22, and are also arranged along the circumferential direction at the center portion Ce. In the present embodiment, the plurality of protrusions 3 are arranged on the same virtual circle at regular intervals, but the present invention is not limited to this. For example, the arrangement interval may not be constant, and may not be arranged on the same virtual circle.

  Although not shown, a heating plate that generates heat when a magnetic field is generated is provided on the bottom surface of the main body 10 in order to cope with IH (electromagnetic induction heating).

  As mentioned above, the cooking pot of this embodiment is provided with the container main body 1 for accommodating a foodstuff, and the cover body 2 which obstruct | occludes opening of this container main body 1, and is a lid which opposes a foodstuff. A plurality of protrusions 3 projecting downward are formed on the inner surface of the body 2.

  According to this configuration, when the steam tries to convect along the inner surface of the lid body 2, the steam is directed downward by colliding with the protrusion 3 protruding downward, so that the protrusion 3 is not formed. Compared to the case, the circulation of steam can be promoted.

  In the present embodiment, the protrusion 3 is a spherical protrusion having a diameter of 2 mm to 9 mm and a height of 1.5 mm to 4 mm.

  According to this configuration, it is possible to prevent the steam circulation from being hindered and to appropriately exert the effect of promoting the steam circulation.

  In this embodiment, the spherical protrusion 3 has a diameter of 5 mm or 6 mm and a height of 2 mm, which is preferable.

  In the present embodiment, the annular ridge 22 is formed on the inner surface of the lid 2 by the peripheral edge Ri rising upward from the central portion Ce, and a plurality of protrusions 3 are formed on the top surface 22 a of the annular ridge 22. Are arranged along the circumferential direction.

  According to this configuration, the steam tries to convect in the radial direction along the annular ridge 22, and the steam to convect along the annular ridge 22 can be appropriately stirred to promote the circulation of the steam. It becomes possible to make it.

  In this embodiment, since the said cover body and the said container main body are formed with the aluminum cast, a foodstuff can be heated with the whole pan with the aluminum excellent in heat conductivity, and can cook rice more skillfully.

  As mentioned above, although embodiment of this invention was described based on drawing, it should be thought that a specific structure is not limited to these embodiment. The scope of the present invention is shown not only by the description of the above-described embodiment but also by the scope of claims, and further includes meanings equivalent to the scope of claims and all modifications within the scope.
