FIG. 2 is a diagram illustrating a state in which the hot plate 100 of FIG. 1 is disassembled. 3 is a cross-sectional view taken along the line AA in FIG.

  As shown in FIGS. 1 to 3, the hot plate 100 according to the present embodiment includes an iron plate part 110 having a high thermal conductivity, a glass part 120 having a low thermal conductivity, a heating material 130 as a heat source, and heat insulation. A mechanism 140 and an outer frame 150 are mainly provided. The size of the hot plate 100 may be arbitrary. For example, the outer dimension (or outer diameter) is about 50 to 60 cm for home use, and the outer dimension (or outer diameter) is 1 m or more for business use. Then, it demonstrates without distinguishing this point. Hereinafter, the components of the hot plate 100 will be described in order.

(Iron plate part 110)
The iron plate part 110 is an example that constitutes the first region of the present invention, and may be referred to as a heating region because of the properties described below. The iron plate part 110 comprises a part of cooking surface, and is heated with the heat from the heat generating part 130 mentioned later. The iron plate part 110 is made of a material having higher thermal conductivity than a glass part 120 described later, for example, a metal such as aluminum, stainless steel, or iron. The cooking surface side of the iron plate part 110 can perform surface treatment processing. In addition, although the area | region actively heated among cooking surfaces is called an iron plate part, this is only using conventional expression (teppanyaki etc.) for convenience of explanation. The material of the iron plate part 110 is not necessarily a steel material.

  The shape of the iron plate portion 110 is circular (infinite square) in the example shown in FIGS. 1 and 2, but may be any shape. For example, it may be a polygon such as a triangle, a rectangle, a pentagon, or a hexagon. Moreover, if the number of users of the hot plate 110 is specified, the shape of the iron plate portion 110 may be an n-gon according to the number of users n. Moreover, the edge part of the iron plate part 110 is good also as a raised shape in order to prevent that a foodstuff spills from a cooking surface.

  As shown in FIGS. 1 and 2, the iron plate part 110 can be separated into four parts 110a to 110d, and these four parts 110a to 110d are in a combined state when used. It is convenient to divide into a plurality of parts 110a to 110d when the iron plate part 110 is stored, maintained, or moved. The number of parts is not limited to four and may be arbitrary.

  In addition, the type of the iron plate part 110 varies depending on the use, and in addition to the flat type shown in FIGS. 1 to 3, various shapes such as a deep pan type, a pancake type or a takoyaki type can be exchanged and used. It is. The thickness, size, and the like of the iron plate portion 110 can be the same as those of these general cooking devices.

(Glass part 120)
The glass part 120 is an example which comprises the 2nd area | region of this invention, and may be called a non-heating area | region on the property described below. The glass part 120 has a lower thermal conductivity than the iron plate part 110 described above. That is, the thermal conductivity of glass is 1 watt per meter Kelvin (W / (m · K)), and the thermal conductivity of iron is 8 watts per meter Kelvin (W / (m · K)). For this reason, since the temperature rise of the glass part 120 is suppressed, containers, such as glass for foodstuff installation and ceramics, can be mounted in the glass part 120. FIG. These containers can be used with various shapes such as a flat dish type, a deep dish type, and a bowl type.

  The glass part 120 is comprised as an area | region including the center part of a cooking surface. In the example shown in FIGS. 1 and 2, the shape of the glass portion 120 is the same circle as the iron plate portion 110, and the diameter thereof can be about 1/3 to 1/2 of the iron plate portion 110. However, this is only an example, and the shape and size of the glass part 120 may be arbitrary.

  As shown in FIG. 1, the iron plate part 110 and the glass part 120 constitute a substantially flat surface when all the components are accommodated in the outer frame 150, that is, constitute a cooking surface. The iron plate part 110 and the glass part 120 can be configured to be flush with each other. When the cooking surface becomes a flat surface, when the food material is placed directly on the glass portion 120, the food material is easily moved to the iron plate portion 110, and cooking is easy. It is also easy to clean and care. Furthermore, it is also possible to use the food in the glass portion 120 so that the food is not heated too much during cooking.

(Heat generating material 130)
The heat generating material 130 generates heat by electric power supplied from the outside. In addition, in FIG. 1, although the heat generating material 130 is shown schematically, the specific structure of the heat generating material 130 may be arbitrary, for example, a heating wire.

  As shown in FIGS. 2 and 3, the shape of the heat generating material 130 is a shape that matches the iron plate part 110. That is, the heat generating material 130 is disposed only in a portion corresponding to the iron plate portion 110. The heat generating material 130 generates heat in a space between the heat generating material 130 and the iron plate portion 110, and cooking is possible by heating the iron plate portion 110.

  As shown in FIG. 2, the heat generating part 130 can be separated into two parts 130a and 130b, and these two parts 130a and 130b are combined in use. Here, the “combined state” may be combined using structural or mechanical means, or may be simply arranged adjacent to each other.

(Insulation mechanism 140)
As shown in FIGS. 2 and 3, the heat insulating mechanism 140 includes a heat insulating material 142 disposed between the iron plate portion 110 and the heat generating material 130 and the glass portion 120, the iron plate portion 110 and the heat generating material 130, and the outer frame 150.

On the other hand, the heat insulating material 144 insulates between the iron plate part 110 and the outer frame 150 and also insulates between the heat generating material 130 and the outer frame 150. The heat insulating material 144 is for protecting the outer frame 150 from heat. However, depending on the heat resistance of the outer frame 150, the heat insulating material 144 is not necessarily provided.

  The heat insulating materials 142 and 144 may be formed integrally with other components. The heat insulating materials 142 and 144 may be integrated (integrated).

  As a material of the heat insulating materials 142 and 144, for example, Porextherm XPS (registered trademark) manufactured by Kurosaki Harima Co., Ltd. can be used (http://krosaki-fc.com/wds/index.html). The heat insulation performance is about 0.025 in an environment of 400 degrees Celsius, which is better than air (http://krosaki-fc.com/wds/wds2.html).

  A general hot plate is provided with a cooling mechanism. As the cooling mechanism, an air cooling mechanism that convects air is employed. For this reason, in order to ensure sufficient air convection space, the total height of the hot plate tends to be high. In the hot plate 100 of this embodiment, it is not necessary to provide such an air convection type air cooling mechanism by providing the heat insulation mechanism 140, or even if an air convection type air cooling mechanism is provided, the air convection Space can be kept small. For this reason, compared with a general hot plate, the total height of the hot plate 100 can be lowered. The hot plate 100 is placed on the table and is easy to use for small children and the elderly, and it is easy for everyone to cook.

  In this embodiment, the example using a heat insulating material was demonstrated as a simple and suitable example of a heat insulation mechanism, but this invention is not limited to this. Any mechanism that can achieve heat insulation is not necessarily limited to a mechanism that uses what is called a heat insulating material. For example, a mechanism using air (gas), water (fluid), gel, vacuum (reduced pressure), or the like may be used.

(Outer frame 150)
As shown in FIGS. 1 and 2, the outer frame 150 accommodates the above-described iron plate part 110, glass part 120, heating material 130, heat insulation mechanism 140, and the like in its inner part, and the shape maintaining function of the hot plate 100.

The outer shape of the outer frame 150 may be matched to the shape of the iron plate portion 110 as shown in FIGS. 1 and 2, or may be a shape (polygon, circle, etc.) different from the iron plate portion 110.

  In addition, the outer frame 150 has a temperature adjustment switch, an air supply fan necessary for the air cooling mechanism, a current supply mechanism, a temperature adjustment measurement mechanism, and an air supply fan, as in a general hot plate. Necessary ones such as a mechanism for supplying current to the can be provided.

  In addition, although not shown, a lid for assisting cooking can be provided in the same manner as a general hot plate. The lid can be made of metal, glass, resin, or the like. Such a lid may be a lid that matches the shape of the outer frame 150, or may be a lid that matches the shape of the iron plate portion 110 or a lid that matches the shape of the glass portion 120.

  The configuration of the hot plate 100 according to the present embodiment has been described above. Hereinafter, a method of using the hot plate 100 will be described.

  As shown in FIG. 4, foodstuff, glass for placing foodstuff, or a ceramic container can be placed on the glass portion 120 of the hot plate 100. Since ingredients and the like are placed in the central portion of the hot plate 100, all the participants can easily cook. It is possible to prevent foods and the like from being placed only at the hands of a specific person, to realize a situation where many people can easily cook, and it is possible to produce a place where everyone can participate.

  Since the iron plate part 110 and the glass part 120 which are cooking surfaces are the same, it is easy to move ingredients during cooking. Moreover, the temperature rise of the glass part 120 is suppressed and it will be in a non-heating state substantially. For this reason, the foodstuff which was heated too much can also be evacuated.

(Effects of the first embodiment)
As described above, according to the present embodiment, a part of the cooking surface is the glass part 120 having a relatively low thermal conductivity, or a heat insulating material is provided around the glass part 120 for heat insulation. Thus, by suppressing the temperature rise of the glass portion 120, it is possible to place a dish or bowl on which the food material or the like can be placed on the glass portion 120, or to directly place the food material. In this way, it is possible to prevent foods and the like from being placed only at the hands of a specific person, to realize a situation where many people can easily cook, and it is possible to produce a place where everyone can participate .

  As an application example of this embodiment, the form of the temperature adjustment unit 770 may be arbitrary. For example, a controller fixed to the side surface of the outer frame 750, a controller provided in the middle of an electric cord led out from the outer frame 750, and the like can be considered. Such a controller may be provided separately for each of the heat generating portions 730a to 730d of the heat generating material 730, or the temperature of all the heat generating portions 730a to 730d may be adjusted in one place.

  Further, the number of parts 710a to 710d of the iron plate portion 710, the heat generating portions 730a to 730d of the heat generating material 730, and the number of sensors 760 are not limited to four, and may be arbitrary. Further, the number may not be a corresponding number.

  As mentioned above, although preferred embodiment of this invention was described referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to this example. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are naturally within the technical scope of the present invention. Understood.

  For example, in the above embodiment, the cooking surface and the outer diameter are circular, but the present invention is not limited to this. As shown in FIG. 9, the cooking surface and outer diameter may be a polygon such as a quadrangle. In the example of the hot plate 300 shown in FIG. 9, the cooking surface has a rectangular outer shape. And the glass part 320 which is a 2nd area | region (non-heating area | region) was made into the strip | belt shape covering the left-right whole including the center part of a cooking surface, and shall consist of three parts 320a-320c. And the upper and lower sides were made into the iron plate part 310 which is a 1st area | region (heating area | region), and shall consist of two parts 310a and 310b.

  10 and 11 illustrate other variations. The hot plate 400 of FIG. 10 has a cooking surface with a circular outer shape, a glass portion 420 that is a second region (non-heated region) having a square shape, and an iron plate portion 410 that is a first region (heating region). Is. A hot plate 500 in FIG. 11 has a cooking surface having a quadrangular shape, a steel plate portion 510 serving as a first region (heating region) having a cross shape including a central portion of the cooking surface, and a second region (non-heating region) around the periphery. ) Are provided with four glass portions 520. As described above, the second region (non-heated region) may not necessarily be a region including the center portion of the cooking surface.

  Moreover, in the said embodiment, although the iron plate part (1st area | region) and the glass part (2nd area | region) gave and demonstrated the example which is the same, this invention is not limited to this. As shown in the hot plate 600 of FIG. 12, the glass portion 620 that is the second region (non-heated region) is made higher than the iron plate portion 610 that is the first region (heated region), or glass The part 620 may be made lower than the iron plate part 610. Moreover, the shape of the iron plate part 610 and the glass part 620 is not limited to a flat surface, and irregularities may be provided.

  Moreover, although the said embodiment demonstrated that a cooking surface was comprised with an iron plate part (1st area | region) with high heat conductivity, and a glass part (2nd area | region) with low heat conductivity, this invention is this. It is not limited to. By providing a heat insulating mechanism between the first region and the second region and between the second region and the heat source, the temperature increase in the second region can be suppressed. By doing in this way, the 2nd field does not necessarily need to be constituted with a material with comparatively low thermal conductivity. For example, the first region and the second region are composed of the same material (for example, the entire surface is an iron plate, the entire surface is a glass plate, etc.), or the second region is composed of a material having higher thermal conductivity than the first region (for example, It is also possible to use an iron plate at the center and a glass plate at the periphery.

  Moreover, although the said embodiment demonstrated that a heat source was arrange | positioned only in the part corresponding to an iron plate part (1st area | region), this invention is not limited to this. For example, by providing a heat insulating material between the first region and the second region and between the second region and the heat source, the temperature increase in the second region can be suppressed. In this way, the heat source may be provided on the entire surface.

  Moreover, although the said embodiment demonstrated the example which can isolate | separate an iron plate part and a heat-emitting part into plurality, this invention is not limited to this. Either or both of the iron plate part and the heat generating part may be inseparable. Moreover, even if it can be separated, the number of separation may be arbitrary. The number of separation of the iron plate portion and the heat generating portion may be different.

  Moreover, in the said embodiment, various forms, such as circular and a polygon, were demonstrated as a shape of the cooking surface of a heat cooking apparatus. You may match the shape of the cooking surface of a heating cooking apparatus with the shape of the table which installs a heating cooking apparatus. For example, a cooking device having a hexagonal (n-gonal) cooking surface or outer shape can be installed in the center of a hexagonal (n-square) table. It can be used as a table for 6 people (n people) at restaurants such as okonomiyaki and yakiniku restaurants.
