Description

  The present invention relates to a water seal pan.

  Conventionally, clay pots have been widely used in Japan as heating cookers because of the softness of the fire and high heat retention. In recent years, IH-type earthen pots that can be cooked with an electromagnetic cooker (hereinafter referred to as IH (Induction Heater) cooker) and IH-type rice pots that are dedicated to cooking rice have been developed. The IH type pan and the IH type rice pan have a structure that can be heated on the IH cooker by the principle of electromagnetic induction.

  For example, when cooking rice in a clay pot, it is possible to cook delicious rice with a plump texture by increasing the pressure inside. In addition, even when cooking boiled dishes in an earthenware pot, meat and vegetables can be boiled softly by keeping the inside at high pressure.

  However, conventional earthenware pots, IH type earthenware pots, and IH type rice pots have a problem that it is difficult to keep the inside at high pressure because the inside airtightness is low even when the lid is covered.

  Then, an object of this invention is to provide the water seal pan which can keep an inside higher pressure.

  In order to solve the above-mentioned problems, a water seal pan according to the present invention includes a pan body, a lid that covers the pan body, and a ring-shaped water reservoir that makes a round around the opening edge of the pan body that the lid contacts. A water seal is formed by the water reservoir groove.

  According to the water seal pan of the present invention, the inside can be kept at a higher pressure.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

<First embodiment>
FIG. 1 is a front view of a water seal pan 100 according to a first embodiment of the present invention. As shown in the figure, the water seal pan 100 includes a clay pot main body 1 that is a container main body and a lid body 2.

  The earthenware pot main body 1 is made of ceramics (including both ceramic and porcelain cases) and has a substantially cylindrical shape that accommodates cooking materials as a heatable water seal pot.

  FIG. 2 is a side view of the water seal pan 100. FIG. 3 is a bottom view of the water seal pan 100. Moreover, FIG. 4 is sectional drawing at the time of cut | disconnecting the earthenware pan main body 1 and the cover body 2 by the line AA of FIG. As shown in FIG. 2, the side surface of the earthenware pot main body 1 has a wavy contour shape from the pot bottom 3 side toward the lid 2 side. Such a side surface shape is formed by providing a plurality of steps at predetermined intervals t (for example, 1 cm to 2 cm intervals) from the pot bottom 3 side of the clay pot body 1 toward the lid body 2 side, as shown in FIG. It has been done. The earthenware pot main body 1 can maintain high strength against impact from the lateral direction due to such a step. Moreover, it is hard to slip when holding the earthenware pot main body 1 by hand by formation of a level | step difference, and it can prevent falling on a floor etc.

  In addition, in order to improve the heat retention inside a clay pot, the side surface of the clay pot main body 1 is formed with a thickness of about 6 mm to 10 mm, for example.

  Moreover, the fluorine processing is given to the inner bottom face vicinity (only a bottom face may be sufficient) of the earthenware pot main body 1. Thereby, when rice is cooked with the water seal pan 100, it is possible to prevent strong burns and to make an appropriate boil. In addition, it is possible to prevent scorching even when making boiled dishes.

  The earthenware pot main body 1 has a pot bottom 3, an opening edge 4, and a handle 5.

  The pot bottom 3 is a part that comes into contact with a heat source such as a gas cooker or an IH cooker when the clay pot body 1 is heated, and is attached to a ceramic bottom surface that is a part of the clay pot body 1 and the bottom surface. And a metal plate such as aluminum or stainless steel. In addition, such a metal plate may be embedded in the outer side and inner side of the pan bottom 3, and also inside the bottom. Further, when embedding the metal plate, the metal plate may be formed in a net shape, or may be a belt-like body that stretches and contracts by applying fine waves. Moreover, it is good also as a some board and a bar piece. Thereby, it can prevent that a metal plate isolate | separates from a ceramic by the shrinkage | contraction at the time of sintering of a clay pot, and the expansion-contraction by a temperature change.

  The pan bottom 3 has a structure in which a metal plate in contact with the IH cooker self-heats by induction heating, and the heat is transmitted to the bottom surface of the earthenware pot body 1. In addition, in order to make the thickness of a bottom face easy to transmit the heat from a metal plate, it is formed with the thickness of about 3 mm-5 mm, for example.

  The opening edge 4 is an edge having a predetermined width (for example, 5 mm to 1 cm width) provided around the opening of the earthenware pot body 1, and is a part on which the end 7 of the lid body 2 is placed.

  The handle 5 is a part that is gripped when the earthenware pot main body 1 is lifted, and is provided in a shape protruding from the outer side surface of the earthenware pot main body 1.

  On the back surface of the handle 5, a convex portion 6 that protrudes toward the pan bottom 3 side is formed. The convex portion 6 is provided to make it difficult for the finger to slip when the handle 5 is gripped. In addition, the convex part 6 may be integrally formed with the earthenware pot main body 1 made of ceramics, or may be one obtained by bonding and fixing a rubber material or a silicone material.

  The lid 2 is a ceramic lid that covers the opening of the clay pot body 1 and has a dome shape (or conical shape). FIG. 5 is a plan view of the water seal pan 100 as viewed from above. The lid 2 has an end portion (end surface) 7 and a grip portion 8.

  The end 7 is located at the opening end of the lid 2 opposite to the gripping portion 8, and is a part that abuts the opening edge 4 of the clay pot body 1 when the lid 2 is put on the clay pot body 1. Further, a packing is fitted into the end portion 7 so that the airtightness inside the earthenware pot is enhanced when the lid body 2 is covered. Details of the packing will be described later.

  The grip portion 8 is a portion that is gripped when the lid body 2 is lifted, and is provided in the vicinity of the dome apex opposite to the end portion 7.

  FIG. 6A is a partially enlarged view showing the opening edge 4 of the earthenware pot main body 1 and the end 7 of the lid body 2. As shown in the drawing, a packing 10 that goes around the open end is fitted into the end 7 of the lid 2. The packing 10 has a groove-shaped (concave) cross-sectional shape into which the end 7 of the lid body 2 is fitted, and is formed in a ring shape that goes around the open end.

  In addition, the packing 10 is formed from the elastic body (elastomer) which has heat resistance, such as a silicone material and a rubber material, for example.

  When such a lid body 2 with packing 10 is put on the opening edge 4 of the earthenware pot body 1, the airtightness inside the earthenware pot body 1 is enhanced. Therefore, the inside of the earthenware pot main body 1 can be made into a high pressure by heating. Therefore, IH-style clay pots can be used to cook plump and delicious rice and to make soft stewed dishes. Furthermore, when making a simmered dish over time by low heat, since heat is not missed by the packing 10, energy saving can be achieved. In addition, the opening edge 4 forms a peripheral wall surface with a rounded corner at the outer periphery of the bottom so as to leave a gap between the end 7 and a height of about 1 cm or more. Thereby, the opening edge 4 not only plays a role of receiving the end portion 7, but also suppresses the spillage of steam and broth that jumps out from the end portion 7 to the outside of the main body.

  Moreover, FIG.6 (b) is the elements on larger scale which showed the edge part 7 of the earthenware pot main body 1 and the cover body 2 which concern on the 1st modification of above-mentioned embodiment. As shown in the drawing, in the first modified example, the packing 11 is attached to the opening edge 4 of the earthenware pot main body 1 at a position where the end 7 of the lid 2 abuts. The packing 11 has a rectangular or elliptical cross-sectional shape and is formed in a ring shape that goes around the opening edge 4.

  In addition, such a packing 11 may be attached to the contact surface by the side of the cover body edge part 7 contact | abutted to the opening edge 4 of the earthenware pot main body 1. FIG.

  Also by such a 1st modification, the airtightness inside the earthenware pot main body 1 is improved moderately. Therefore, the inside of the earthenware pot main body 1 can be made into a high pressure by heating.

  Moreover, Fig.7 (a) is the elements on larger scale which showed the edge part 7 of the earthenware pot main body 1 and the cover body 2 which concern on the 2nd modification of above-mentioned embodiment. As shown in the drawing, the opening edge 4 of the earthenware pot body 1 according to the second modification is formed with a recess 20 (groove) that goes around the opening edge 4. In addition, a ring-shaped packing 12 having a rectangular or elliptical cross-sectional shape and surrounding the opening edge 4 is attached to the bottom 21 of the recess 20 of the opening edge 4.

  Here, the thickness of the packing 12 is set to a thickness that is lower than the upper end 22 of the recess 20. That is, the depth of the recess 20 is set to be larger than the thickness of the packing 12. With such a configuration, the water 23 can be stored in the recess 20 above the contact surface between the packing 12 and the lid end 7. The water 23 accumulated in the dent 20 forms a water seal and improves the airtightness inside the clay pot body 1.

  In addition, you may make it form a water seal by the dent 20 provided in the opening edge 4 of the clay pot main body 1 without providing the packing 12. FIG. 7B is a partially enlarged view showing the earthenware pot main body 1 and the lid end 7 in a state where the packing 12 is not provided in the recess 20 of the opening edge 4.

  As shown in the figure, the lid end 7 abuts the recessed bottom 21 at a position lower than the recessed upper end 22. With such a configuration, the water 23 can be stored in the recess 20 to the upper side than the contact surface between the lid end 7 and the recess bottom 21. In addition, it is not necessary to intentionally store the water 23 in the dent 20, and water vapor generated from the inside of the earthenware pot body 1 by heating becomes water and accumulates in the dent 20. The water 23 accumulated in the dent 20 forms a water seal and improves the airtightness inside the clay pot body 1.

  FIG. 8 is a partially enlarged view showing the earthenware pot main body 1 and the lid end portion 7 according to the third modification of the embodiment described above. As shown in the drawing, a packing 13 (ring seal, lip seal) is attached to the opening edge 4 of the earthenware pot body 1 according to the third modified example at a position where the lid end 7 abuts. The packing 13 has a substantially square cross-sectional shape and is formed in a ring shape that goes around the opening edge 4.

  The packing 13 includes a thick portion 14 that contacts the side wall of the opening edge 4 and a thin portion 15 that contacts the lid end 7. As shown in the figure, when the lid body 2 is put on the opening edge 4 of the earthenware pot main body 1, the thin portion 15 is pushed and bent in the direction of the thick portion 14 so as to be crushed by the lid body end portion 7. Due to such deformation of the packing 13, the airtightness inside the earthenware pot main body 1 is enhanced in a state where the lid 2 is covered.

  Moreover, you may make it improve the adhesiveness of the packing 13 and a side wall by providing a level | step difference in the side wall of the opening edge 4. FIG. FIG. 9 is a view showing a state in which the packing 13 is tightly fixed to the side wall provided with the step 30. By providing such a step, it is difficult for the packing 13 to come off from the side wall, and the airtightness inside the earthenware pot main body 1 can be enhanced in a state where the lid 2 is covered.

  The water seal pan according to the present embodiment is not limited to a clay pan, and may be a metal pan (for example, aluminum or stainless steel) or a pan. The cooking container may be a clay pot or a pan that can be heated by an IH cooker.

  In that case, the pot bottom 3 should just have the ceramic bottom face which is a part of the earthenware pot main body 1, and metal plates, such as aluminum and stainless steel, affixed on this bottom face. In addition, such a metal plate may be embedded in the outer side and inner side of the pan bottom 3, and also inside the bottom. A metal plate formed in a net shape is used. Thereby, it can prevent that a metal plate will isolate | separate by shrinkage | contraction at the time of sintering of a clay pot.

  The pan bottom 3 has a structure in which a metal plate in contact with the IH cooker self-heats by induction heating, and the heat is transmitted to the bottom surface of the earthenware pot body 1. In addition, in order to make the thickness of a bottom face easy to transmit the heat from a metal plate, it is formed with the thickness of about 3 mm-5 mm, for example.
