Water seal pot

The present invention relates to a water seal pan. The present invention claims the priority of the Japanese utility model registration application number 2013-509 filed on January 31, 2013, and the designated countries that are allowed to be incorporated by reference to the documents are described in the application. The contents are incorporated into this application by reference.

Traditionally, 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, by making the inside high-pressure, you can cook delicious rice with a plump texture. 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 internal airtightness is low even when the lid is covered.

Therefore, an object of the present invention is to provide a water seal pan that can keep the inside at a higher pressure.

In order to solve the above-described 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 goes around the opening edge of the pan body that the lid contacts. A water seal is formed by the water reservoir groove.

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 the 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. FIG. 4 is a cross-sectional view of the earthenware pot body 1 and the lid body 2 taken along the line AA in 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 a predetermined interval t (for example, 1 cm to 2 cm intervals) from the bottom 3 side of the earthenware pot body 1 to the lid 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, the side surface of the clay pot body 1 is formed with a thickness of about 6 mm to 10 mm, for example, in order to enhance the heat retention inside the clay pot.

In addition, near the inner bottom surface of the earthenware pot body 1 (only the bottom surface may be used) is subjected to fluorine processing. 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.

Moreover, 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 earthenware pot body 1 is heated. 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. Furthermore, the surface of the metal surface may be coated or baked with ceramics for protecting the metal surface. 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 clay pot main body 1. In order to make it easier to conduct heat from the metal plate, the thickness of the bottom surface is, for example, about 3 mm to 5 mm in a pan for normal cooking, and prevents burning in a pan for cooking rice. In order to achieve this, it is desirable to form with a thickness of about 6 mm to 10 mm.

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 main body 1, and is a part on which the end 7 of the lid 2 is placed.

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

The convex part 6 which protrudes toward the pan bottom 3 side is formed in the back surface of the handle 5. 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 earthenware 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 portion 7 is located at the opening end of the lid body 2 on the side opposite to the gripping portion 8, and is a portion that comes into contact with the opening edge 4 of the clay pot body 1 when the lid body 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. 6 (a) is a partially enlarged view showing the opening edge 4 of the earthenware pot body 1 and the end 7 of the lid 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.

The packing 10 is made of an elastic body (elastomer) having heat resistance such as a silicone material or a rubber material.

When the lid 2 with the 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 on the side of the lid end 7 that contacts the opening edge 4 of the clay pot body 1.

Even with such a first modification, the airtightness inside the earthenware pot body 1 is moderately increased. Therefore, the inside of the earthenware pot main body 1 can be made into a high pressure by heating.

FIG. 7A is a partial enlarged view showing the end portion 7 of the earthenware pot body 1 and the lid body 2 according to the second modification of the above-described 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 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 on the concave bottom 21 at a position lower than the concave 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 has 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.

Further, by providing a step on the side wall of the opening edge 4, the adhesion between the packing 13 and the side wall may be improved. 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.

In addition, the water seal pan according to the present embodiment is not limited to the earthen pan, and may be a metal pan (for example, aluminum or stainless steel) or a frying 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 only needs to have a ceramic bottom surface, which is a part of the clay pot body 1, and a metal plate such as aluminum or stainless steel attached to the bottom surface. 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 clay pot main body 1. The bottom surface has a thickness of, for example, about 3 mm to 5 mm so that heat from the metal plate can be easily transmitted.

<Second embodiment>
