Description

  The present invention relates to an earthenware pan, and more particularly to an earthenware pan that can be used for both an electromagnetic cooker and an open fire.

  In recent years, as a cooking heat source, an electromagnetic cooker (IH) that generates an eddy current by electromagnetic induction in addition to a heating source by direct fire of gas or the like and thereby heats a cooking container has been widely spread. .

  Generally, an iron cooking container with high permeability and conductivity is used as a cooking container used in an electromagnetic cooker, and an earthen pot not having such characteristics can be cooked using an electromagnetic cooker. It is supposed to be impossible. However, when cooking using an earthenware pan, it has high heat retention due to the far-infrared effect and can be heated slowly, so when cooking using an iron cooking container such as improving the flavor of the cooked food There are no advantageous aspects. For this reason, development of a clay pot that can also be used in an electromagnetic cooker has been desired.

  Therefore, a clay pot in which aluminum is sprayed on the outer bottom surface of the pot body has been proposed so that the pot can be heated using an electromagnetic cooker. According to this earthenware pan, the aluminum sprayed layer formed on the outer bottom surface is heated by the electromagnetic induction eddy current, so that it can be heated using an electromagnetic cooker (see Patent Document 1).

JP-A 64-002287

  However, in the clay pot described in Patent Document 1, when the pan body is heated by direct fire, the aluminum sprayed layer may be peeled off from the pan body due to thermal expansion due to the rapid heating, or when heated by direct fire. There was a problem that it was not possible to cook with an electromagnetic cooker.

  In addition, in the earthenware pot, the portion that is heated by electromagnetic induction of the electromagnetic cooker is limited only to the bottom of the earthenware pot, so when cooking using an electromagnetic cooker, it takes a lot of cooking time, In some cases, there has been a disadvantage that the moisture of the cooked food cannot be boiled.

  The present invention has been made to solve the above inconveniences, and the purpose thereof can be used both for an electromagnetic cooker and for an open fire, particularly when cooking using an electromagnetic cooker. It is to provide a clay pot that can be shortened.

  In the earthenware pot provided with the pan body which has an inner bottom face part, an inner wall face part continuously extended from the circumference of the inner bottom face part, and a lid body which covers the upper opening of the pan body The problem can be solved by forming a heating element layer made of aluminum and a coating layer made of ceramic on the heating element layer at least over the entire upper surface of the inner bottom surface and the inner wall surface.

  As described above, in the above configuration, the heating element layer is formed on the upper surface of the inner bottom surface portion and the inner wall surface portion of the pan body, that is, the entire inner surface of the pan body. That is, even when the pan body is heated by direct fire, the heating element layer is not heated directly, and rapid thermal expansion can be prevented, so the heating element layer is peeled off from the inner surface of the pot body. It is possible to prevent harmful effects such as On the other hand, when the pan body is heated by the electromagnetic cooker, the heating element layer formed on the inner bottom surface generates heat due to the eddy current of electromagnetic induction, so that the pan body can be heated. As described above, in the earthenware pot according to the present invention, any heating source can be used after heating with an open flame or an electromagnetic cooker. A heating source for direct fire can be selected as appropriate.

  Further, in the above configuration, since the heating element layer made of aluminum having an extremely excellent heat transfer property is formed over the entire inner surface of the pan body, the electromagnetic induction vortex is generated when the earthen pan is heated by the electromagnetic cooker. When the heating element layer formed on the inner bottom surface portion generates heat due to the current, the thermal energy is quickly transmitted to the heating element layer formed on the inner wall surface portion. Thus, since the whole inner surface of the pan body can be heated in a very short time, the cooking time required for cooking and the like can be dramatically shortened.

  Furthermore, since the heating element layer is formed of aluminum, its input value can be stabilized as compared with that formed of an aluminum alloy containing other substances such as nickel. When heated, the heating element layer can generate heat uniformly and satisfactorily. In addition, the heating element layer made of aluminum has a higher expansion rate than that made of an aluminum alloy, and can be expanded together with the pan body that expands greatly when heated. Can prevent adverse effects such as peeling from the inner bottom surface and inner wall surface of the pan body.

  Moreover, since aluminum has extremely high corrosion resistance, it is possible to suppress breakage and damage such as cracks due to corrosion.

  In the above configuration, since the ceramic having a certain degree of hardness is coated on the upper surface of the heating element layer, the heating element layer can be well protected from external impacts and the like. Moreover, since ceramic has low water permeability, it becomes possible to suppress the leaching of moisture to the pan body side, and it is possible to suppress the soaking of boiled juice into the pan body and the damage due to the corrosion of the heating element layer. .

  At this time, as in claim 2, the pan body has a locking step portion formed continuously from the periphery of the inner wall surface portion, on which the lid body can be placed, and the locking step portion is It is preferable that the heating element layer and the coating layer are laminated on the entire upper surface. If comprised in this way, a heat generating body layer will be formed in the latching step part of a pan main body, and a cover body will be mounted above this heat generating body layer. That is, when the heating element layer is heated by an electromagnetic cooker or the like, the heat energy is transmitted to the lid body, and thus the lid body can be heated well. Therefore, after cooking with the lid placed on the pan body, the entire earthenware pan (pan body and lid body) is well heated and stored even if heating with an electromagnetic cooker or the like is stopped. The heat retaining function of the earthenware pot can further prevent the food from being cooled.

  At this time, as in claim 3, it is preferable that the heating element layer is formed as an uneven pattern. If comprised in this way, in the inner surface side of a pan main body, since patterns, such as a character and a design, can be formed in three dimensions, it can be set as the design excellent in the design. In addition, since it is possible to directly touch the uneven pattern with the hand, it is possible to satisfy the user's tactile sensation (feel). Furthermore, since such uneven | corrugated shape can also be formed simultaneously, for example, when forming a heat generating body layer on the inner bottom face part or inner wall surface part of a pan main body, in such a case, without increasing an operation process. It becomes possible to form.

  According to a fourth aspect of the present invention, it is preferable that the heating element layer is formed by thermal spraying. If comprised in this way, it will become possible to adhere | attach a heat generating body layer firmly on upper surfaces, such as an inner bottom face part and an inner wall face part of a pan main body. Therefore, even if the earthenware pan is used for a long period of time, it is possible to prevent a decrease in heat transfer performance, peeling and breakage due to thermal expansion, and the like.

At this time, as in claim 5, it is preferable that a finishing layer containing ceramic or fluorocarbon resin as a component is further laminated on the upper surface of the coating layer. If comprised in this way, since the finishing layer which consists of ceramics etc. will be further formed in the upper surface of a coating layer, in addition to the effect by the said coating layer, furthermore, a heat generating body layer is protected effectively from an external impact. In addition, it is possible to surely prevent moisture from leaching to the pan body side. In addition, by forming the finishing layer with a fluorocarbon resin or the like, it becomes possible to suppress scorching or sticking during cooking, and maintenance such as washing after cooking can be simplified.
In addition, the finish layer can contain a colorant such as a pigment, for example, and can be colored, or a pattern such as a letter or design can be applied. In such a case, a clay pot having an excellent design in design is provided. can do.

  As described above, according to the earthenware pot according to the present invention, it is possible to use any heating source after heating with an open flame or an electromagnetic cooker with a simple configuration. During cooking, cooking time can be dramatically reduced.

It is a principal part expanded sectional view of FIG.

  As shown in FIG. 1 thru | or FIG. 6, the earthenware pot 1 which concerns on this embodiment is a container for cooking used in order to cook foodstuff etc., and is comprised from the pan main body 10 and the cover body 50. As shown in FIG. The pan body 10 is formed in a substantially semicircular cross section, and is formed by expanding the inner bottom surface portion 11, the inner wall surface portion 12 rising continuously from the inner bottom surface portion 11, and the upper edge portion of the inner wall surface portion 12. And a locking step 13. The lid body 50 is formed in a substantially arc shape in cross section, and is configured to be fitted and placed in the locking step portion 13 of the pan body 10.

  The pan body 10 is formed by molding using a heat-resistant material that can withstand heat during cooking, and firing at a temperature of about 1200 degrees. The material used for the pan body 10 only needs to have heat resistance capable of withstanding the heat during cooking. For example, it may be formed of a material used in the manufacture of clay pots, such as ceramic stone, lime, and clay. Is possible.

  Moreover, as shown in FIG.5 and FIG.6, in the outer peripheral surface except the inner bottom face part 11, the inner wall face part 12, the latching step part 13, and an outer bottom face part among the pan bodies 10, for example, a fluorocarbon resin (PolyTetraFluorEthylene) is used. The outer surface finishing layer 14 made of an organic paint containing PTFE) is formed by a method such as brushing, spraying or spraying. The outer surface finishing layer 14 can also be formed using the same material as the finishing layer 40 in the step of forming the finishing layer 40 described later.

  Here, for example, when lithium-containing petalite (trade name) is mixed with the material of the pan body 10, it becomes possible to suppress the coefficient of thermal expansion of the pan body (becomes strong against heat shock), and suddenly in an empty fired state. It is extremely suitable because it can prevent adverse effects such as cracking in the pan body due to the difference in thermal expansion, and can enhance the heat storage effect of the pan body by improving the thermal conductivity.

  The heating element layer 20, the coating layer 30, and the finishing layer 40 are provided on the inner bottom surface portion 11, the inner wall surface portion 12, and the locking step portion 13 of the pan body 10 according to the present invention, that is, on the entire inner surface of the pot body 10. Are sequentially laminated.

  The heating element layer 20 is formed in a thin film by spraying fine powders of heated aluminum in a semi-dissolved state so as to have a thickness of about 100 μm or less, preferably about 20 μm to 60 μm. By forming the heating element layer 20 to such a thickness, the heating element layer 20 can be heated favorably by an electromagnetic induction eddy current generated by an electromagnetic induction cooker having a rated voltage of 200 V and an output of 500 to 3000 W. The spraying can be realized by, for example, conventionally used arc spraying, plasma spraying, gas spraying, or the like, or by spraying by spraying.

  Further, the heating element layer 20 is not limited to being formed by aluminum spraying, but can be formed by applying aluminum by brushing or the like and then baking at a temperature of about 400 to 600 degrees. It is.

  The coating layer 30 is formed in a thin film shape on the entire upper surface of the heating element layer 20 by melting or thermally spraying ceramic. Such thermal spraying can be realized by conventionally used arc spraying, plasma spraying, gas spraying, spray spraying, and the like, similarly to the heating element layer 20.

  The finishing layer 40 is formed on the entire upper surface of the coating layer 30 using a technique such as brushing, spraying, or spraying a material made of ceramic. In the present invention, the finishing layer 40 is formed using white ceramic white with the least yellowing. Thus, by using ceramic white for the finishing layer 40, it becomes possible to make the color of the inner surface of the pan body 10 a beautiful white finish without containing a colorant such as a pigment or paint. ing.

  In addition, although the ceramic white was used for the finishing layer 40, it is also possible to form the finishing layer 40 using ceramics other than white containing coloring materials, such as a pigment. Further, the finishing layer 40 has heat resistance such as the above-mentioned ceramic containing a fluorocarbon resin, the other material such as glaze, and the glaze etc. containing ceramic or fluorocarbon resin. If it exists, it can be formed using various materials.

  Thus, according to the clay pot 1 according to the first embodiment, the inner bottom surface portion 11, the inner wall surface portion 12 and the upper surface of the locking step portion 13 of the pot body 10, that is, the entire inner surface of the pot body 20. Since the aluminum is sprayed, when the pan body 10 is heated by an electromagnetic cooker, first, the heating element layer 20 formed on the inner bottom surface portion 11 of the pan body 10 generates heat by electromagnetic induction eddy current. Since the heating element layer 20 is made of aluminum having an extremely excellent heat transfer property, when the heating element layer 20 on the inner bottom surface portion 11 generates heat, the heat energy is then efficiently transferred to the inner wall surface portion 12 and the locking step. It is sequentially transmitted to the heating element layer 20 on the part 13. That is, the entire inner surface of the pan body 10 can be heated in a very short time by the heating action of the heating element layer 20 formed on the inner bottom surface portion 11, the inner wall surface portion 12 and the locking step portion 13 of the pan body 10. Therefore, it is possible to dramatically shorten the cooking time required for cooking.

  Further, since the heating element layer 20 is formed by aluminum spraying, the heating element layer 20 can be firmly attached to the pan body 10. For this reason, even if the earthenware pot 1 is used for a long period of time, it is possible to prevent the heat transferability from being reduced, peeling or breakage due to thermal expansion, and the like.

  Furthermore, since the heating element layer 20 is formed using a material made of aluminum, the current value can be increased, and the heating element layer 20 generates heat well when heated by an electromagnetic cooker. It becomes possible to make it. Moreover, since the heat generating body layer 20 made of aluminum has a high expansion coefficient and can be expanded together with the pan body 10 that expands greatly when heated, the heat generating body layer 20 is the inner bottom surface of the clay pot 1. It is possible to suppress adverse effects such as peeling from the portion 11 and the inner wall surface portion 12.

  In the present embodiment, since the coating layer 30 made of ceramic is formed on the upper surface of the heating element layer 20, the heating element layer 20 is externally impacted by a ceramic having a certain degree of hardness and low water permeability. It is possible to prevent the moisture from leaching to the pan body 10 side. In addition, since the coating layer 30 is formed by thermal spraying, the degree of adhesion to the heating element layer 20 becomes strong, and the coating layer 30 can be prevented from peeling off from the heating element layer 20. Furthermore, since the thickness of the coating layer 30 can be made substantially uniform with respect to the heating element layer 20 by such thermal spraying, the inner surface side of the pan body 10 can be made into a smooth flat shape.

  Further, since a finishing layer 40 made of a material containing ceramic or fluorocarbon resin is further formed on the upper surface of the coating layer 30 made of ceramic, in addition to the function and effect of the coating layer 30, The heating element layer 20 can be protected from external impacts, and moisture can be prevented from leaching to the pan body 10 side. Moreover, since the finishing layer 40 is formed of a material containing a ceramic or a fluorocarbon resin, it is possible to suppress scorching, sticking, etc. during cooking and simplify cleaning such as washing after cooking. It becomes possible.

  Next, a second embodiment according to the present invention will be described with reference to FIG. FIG. 7 is a sectional view of a pan body according to the second embodiment of the present invention. In addition, the second embodiment shown in FIG. 7 is a heating element formed by sequentially laminating on the inner bottom surface portion, inner wall surface portion, and upper surface of the locking step portion of the pan body in comparison with the first embodiment. The only difference is in the form of the layers, the coating layer, and the finishing layer, and the rest of the configuration is the same as that of the first embodiment, so the same reference numerals are assigned and redundant description is omitted.

  As shown in FIG. 7, the earthenware pan 100 according to the present embodiment has a pot body 10 as in the first embodiment, and includes an inner surface bottom portion 11, an inner wall surface portion 12, and a locking step portion 13. On the upper surface, the heating element layer 120, the coating layer 130, and the finishing layer 140 are sequentially laminated.

  The heating element layer 120 is formed so as to protrude in a concavo-convex shape from the upper surface of the inner bottom surface portion 11 and the inner wall surface portion 12 of the pan body 10, and in this embodiment, due to the concavo-convex shape, Patterns such as letters and figures can be formed in three dimensions. Such a concavo-convex shape can be formed by, for example, a conventionally used intaglio printing or tampo printing using a material made of aluminum as a printing liquid, and, similarly to the first embodiment, It can also be formed by performing the above intaglio printing or tampo printing after aluminum spraying. In addition, the said uneven | corrugated shape is not restricted to the case where it forms in the whole region of the inner bottom face part 11 and the inner wall face part 12, You may form only in the inner bottom face part 11, and it is also possible to form only in the inner wall face part 12. is there.

  As in the first embodiment, the coating layer 130 is formed by spraying ceramic over the entire upper surface of the heating element layer 120, and the surface shape thereof has substantially the same uneven shape as the heating element layer 120. ing.

  As in the first embodiment, the finishing layer 140 is coated with ceramic or the like on the entire upper surface of the coating layer 130, and the surface shape thereof has substantially the same uneven shape as the heating element layer 120 and the coating layer 130. ing.

  As described above, according to the second embodiment, it is possible to form a pattern such as a character or a figure three-dimensionally due to the uneven shape of the heating element layer 120. In addition to the effects of the first embodiment, Since the design can be made extremely excellent, and a pattern having a concavo-convex shape can be directly touched with a hand, it is also possible to satisfy the user's tactile feeling (feel).

  Such a concavo-convex shape can be directly formed on the inner bottom surface portion 11 and the upper surface of the inner wall surface portion 12 of the pan body 10 by intaglio printing, tampo printing, or the like when the heating element layer 120 is formed. The heating element layer 120 can be formed without increasing the number of steps.

  In the first embodiment and the second embodiment, the coating layers 30 and 130 are formed on the upper surfaces of the heating element layers 20 and 120, and the finishing layers 40 and 140 are formed on the upper surfaces. However, the finishing layers 40 and 140 may be omitted, and the coating layers 30 and 130 may be used as the finishing surface, or a layer that becomes the finishing surface may be further laminated on the top surface of the finishing layers 40 and 140. .

  Further, although the heating element layers 20 and 120 are formed on the inner bottom surface portion 11, the inner wall surface portion 12 and the locking step portion 13 of the pan body 10, they are formed only on the inner bottom surface portion 11 and the inner wall surface portion 12 of the pot body 10.
