Description

  The present invention relates to a cooking device in which a cooking surface is heated by a heat source.

  A hot plate is known as one of the cooking devices in which the cooking surface is heated by a heat source such as electric or magnetic. In the place of the meal using a hot plate, the place of the meal of the participatory type by the participant who eats together originally is assumed and expected (for example, refer patent document 1). In view of such assumptions and expectations, in the conventional hot plate, the hot plate is placed in the center of the table, and dishes and bowls such as ingredients are placed together in the hands of the cooking leader, not in the center of the table.

JP 2002-153386 A

  However, in a conventional hot plate, only the person who leads the cooking often cooks due to its physical structure. As a result, participants other than those who lead cooking only eat what is cooked. Assuming that there are four participants, three people other than those who lead cooking only watch the cooking process and only eat what the cooking leader has shared.

  This is not much different from a normal meal without a hot plate, and is almost the same as simply moving the kitchen counter to the table. In this case, there is not much sense of participation-type meals, and it may only increase labor. As a result, there is a problem that the significance of using a hot plate is reduced and the use frequency of the hot plate is reduced. Such a problem is not limited to the hot plate, but is a problem common to all cooking apparatuses that assume a participatory type.

  Therefore, the present invention has been made in view of such problems, and the object of the present invention is to provide a new and improved cooking device capable of producing a place for everyone to participate in a meal. There is to do.

  In order to solve the above-described problem, according to a first aspect of the present invention, there is provided a cooking device in which a cooking surface is heated by a heat source, wherein the cooking surface includes a first region composed of a first material and There is provided a cooking device characterized by comprising: a second region composed of a second material having a lower thermal conductivity than the first material.

  According to such a configuration, by setting a part of the cooking surface as the second region composed of the second material having a relatively low thermal conductivity, the dish or bowl on which food or the like can be placed in the second region. It can be placed or food can be placed directly. 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 .

  In order to solve the above problem, according to a second aspect of the present invention, a cooking device in which a cooking surface is heated by a heat source, wherein the cooking surface includes a first region and a second region, A heat cooking apparatus is provided, wherein a heat insulating mechanism is provided between the first region and the second region, and between the second region and the heat source.

  According to such a configuration, by providing a heat insulating mechanism around the second region for heat insulation, it is possible to place a dish or bowl on which food or the like can be placed in the second region, or directly place the food. 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 .

  In the present invention, the first region may be composed of a first material, and the second region may be composed of a second material having a lower thermal conductivity than the first material. In this way, the temperature rise in the second region can be further suppressed.

  The heat source may be disposed only in a portion corresponding to the first region. By arranging the heat source only in the portion corresponding to the first region and not in the portion corresponding to the second region, the temperature rise in the second region can be further suppressed.

  The first area and the second area may be flush with each other. When the foodstuff is directly placed in the second region, the foodstuff is easy to move to the first region and cooking is easy. It is also easy to clean and care. In addition, it is possible to use the food in the second area so that the food is not heated too much during cooking.

  The cooking surface may be a polygon or a circle, and the second region may be a region including a central portion of the cooking surface. By setting the second region as the region including the central portion, ingredients and the like can be placed in the central portion of the cooking surface, and all the participants can easily take the ingredients and cook easily.

  In order to solve the above-mentioned problem, according to a third aspect of the present invention, a cooking device in which a cooking surface is heated by a heat source, wherein the cooking surface has a donut shape, and the heat source has the donut shape. A cooking device is provided, which is arranged only in a portion corresponding to a cooking surface.

  According to such a configuration, the cooking surface has a donut shape, and the central portion of the cooking surface is hollowed out so that a dish or bowl on which the food can be placed is placed in the central portion of the cooking surface. Can be placed directly. 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 .

  In the present invention, the cooking surface may be separable into a plurality of surfaces. It is convenient to divide the cooking device into a plurality of parts when storing, cleaning and moving the cooking device.

  In order to solve the above-described problem, according to a fourth aspect of the present invention, there is provided a cooking device, a first member, a second member made of the same or different material as the first member, and the A heat source for heating the first member, an outer frame that houses the first member, the second member, and the heat source, and a first member provided between the second member, the first member, and the heat source. And the second heat insulating material provided on the entire bottom surface of the second member and the entire bottom surface of the heat source, and the thermal conductivity of the first heat insulating material and the second heat insulating material is There is provided a cooking device characterized by being below the thermal conductivity of still air at room temperature.

  In the Japanese Industrial Standard, “normal temperature” is defined as a range of 20 degrees Celsius plus or minus 15 degrees (5 degrees Celsius to 35 degrees Celsius) (JIS Z 8703). Most Japanese products such as industry, daily necessities, food, etc., and the standards and regulations of products, this temperature range is normal temperature. “Normal temperature” in this specification is also as defined. The second heat insulating material may also be provided between the first member, the heat source, and the outer frame.

  According to such a configuration, since the thermal conductivity of the first heat insulating material and the second heat insulating material is lower than the thermal conductivity of still air at room temperature, there is no need to provide a space for forming an air layer for heat insulation. Or even if provided, it can be lowered. Therefore, the height of the cooking device can be reduced. For this reason, it can reduce that a heat cooking apparatus obstructs a visual field at the time of use, and can eliminate the feeling of pressure received from a heat cooking apparatus.

  The said invention WHEREIN: You may provide the ventilation fan for cooling the heat from the said heat source by the convection of air. Even if the heat insulating material is used, the cooling fan forcibly cools the heat transmitted slightly from each member, so that the cooling efficiency is improved as compared with the conventional cooling that relies on natural convection of air. Therefore, the clearance gap between each member can be made small and the height of a heating cooking apparatus can be made still lower.

  The heat source may be a sheet type heater. Since the thickness of the heat source itself can be reduced by using the sheet heater, the height of the cooking device can be further reduced.

  The heat source may be a sheet type heater whose entire upper surface is covered with a covering member. By using a sheet-type heater whose entire upper surface is covered with a covering member, for example, a heater that is easily broken by impact, such as a mica heater, can be protected by the covering member. Therefore, since a heater with a small thickness can be used, the height of the cooking device can be further reduced. In addition, it is not necessary to cover the lower surface of the heat source with a covering member because there is a heat insulating material. Also in this respect, the height of the cooking device can be reduced.

  Further, the height from the installation surface to the upper end of the outer frame may be 6 cm or less. More preferably, the height from the installation surface to the upper end of the outer frame can be 5 to 6 cm. The point where the finger supports chopsticks, forks, etc. is about 5-6 cm above the desktop. Therefore, when using a cooking device on the table, hold the chopsticks or fork in your hand to pick up the ingredients, lift the hand placed on the table and take the ingredients on the cooking device, and cook The height to the upper end of the outer frame of the apparatus is the same height. Therefore, the user can feel “easy to use”.

  Further, the height from the installation surface to the cooking surface of the first member may be 5 cm or less. More preferably, the height from the installation surface to the cooking surface of the first member can be 4 to 5 cm. When placing food on the cooking surface or picking up food prepared from the cooking surface, the height of lifting the hand is 5 cm or less. For this reason, since the user's finger can work at a height of about 5 to 6 cm above the desktop, which is a point that supports chopsticks, forks, etc., the user can feel "easy to use". .

  According to the cooking device of the present invention, it is possible to produce a place for all-participant meals. The other effects of the present invention will be described in the section for carrying out the invention below.

In addition, in this specification and drawing, about the component which has the substantially same function structure, duplication description is abbreviate | omitted by attaching | subjecting the same code | symbol. In the following embodiment, a hot plate will be described as an example of a cooking device, but the present invention is not limited to the hot plate.

(First embodiment)
A first embodiment of the present invention will be described. FIG. 1 is a diagram schematically showing a configuration of a hot plate 100 according to the present embodiment. 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 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 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. It is convenient to divide the heat generating part 130 into a plurality of parts 130a, 130b when storing, cleaning, moving, or the like. The number of parts is not limited to two and may be arbitrary. Moreover, it may be the same as the number of parts of the heat generating part 110 mentioned above, and may differ.

(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. It is comprised with the heat insulating material 144 distribute | arranged between.

  As shown in FIG. 3, the heat insulating material 142 insulates between the iron plate part 110 and the glass part 120 and also insulates between the glass part 120 and the heat generating material 130. 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 .

  In addition, the cooking surface is circular and the glass portion 120 is an area including the center of the cooking surface, so that ingredients can be placed in the center of the cooking surface, making it easy for all participants to take the food and cooking. Cheap.

  Further, since the cooking surface can be separated into a plurality of surfaces, it can be conveniently divided into a plurality of parts when the hot plate 100 is stored, maintained, or moved.

  A thin sheet heater is used for the heat generating material 730 of the present embodiment. As shown in FIG. 13, the heat generating member 730 is covered with a covering member 732 on the entire upper surface of the flat heater 731. As the flat heater 731, for example, a mica heater is used. Although the mica heater is easily broken by an impact, the upper surface of the flat heater 731 can be protected by the covering member 732 even when the flat heater 731 that is easily broken by an impact like the mica heater is used. In addition, it is not necessary to cover the lower surface of the flat heater 731 with a covering member. This is because a high-performance heat insulating mechanism 740 (heat insulating material 744) described below is provided on the lower surface of the flat heater 731.

  The heat insulating mechanism 740 includes a heat insulating material 742 disposed between the iron plate portion 710 and the heat generating material 730 and the glass portion 720, and a heat insulating material 744 disposed between the iron plate portion 710 and the heat generating material 730 and the outer frame 750. Consists of. Note that the heat insulating material may be provided only on the bottom surface of the heat generating material 730 instead of the structure of the heat insulating material 744. That is, the heat insulating material may not be provided between the iron plate portion 710 and the heat generating material 730 and the outer frame 750. This is because the heat generating material 730 is a thin sheet-type heater, and therefore, the influence of heat on the side of the heat generating material 730 is small.

  The heat insulating materials 742 and 744 are configured such that the thermal conductivity is lower than the thermal conductivity of still air at normal temperature (20 degrees Celsius plus or minus 15 degrees). Specifically, for example, Porextherm XPS (registered trademark) of Kurosaki Harima Co., Ltd. can be adopted as a material for the heat insulating materials 742 and 744 (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).

  Thus, the hot plate 700 of this embodiment uses the heat insulating materials 742 and 744 whose thermal conductivity is lower than the thermal conductivity of still air at normal temperature (20 degrees Celsius plus or minus 15 degrees). For this reason, an air layer for heat insulation is not required between the heat generating material 730 and the outer frame 750, or even if it is provided, it can be lowered.

  Further, the hot plate 700 uses a heating material 730 of a sheet type heater in which the entire upper surface of the flat heater 731 is covered with a covering member 732. Thus, the thickness of the heat generating material 730 itself is also thin.

  Further, the hot plate 700 includes a blower fan (not shown) between the outer frame 750 and the heat insulation mechanism 740 for cooling the heat from the heat generating material 730 by air convection. As a result, even if the heat insulating materials 742 and 744 are used, the cooling fan forcibly cools the heat that is slightly transmitted from each member, so that the cooling efficiency is lower than the cooling that relies on the natural convection of air as in the past. Will improve. Therefore, the clearance gap between each member can be made small. In the present embodiment, the blower fan is provided between the outer frame 750 and the heat insulating mechanism 740, but the present invention is not limited to this example. The blower fan can be provided at an appropriate position on the hot plate 700 as long as it can be blown into the gaps between the members.

(Effect of the third embodiment)
As described above, according to the present embodiment, the height when the hot plate 700 of the present embodiment is installed on a table can be reduced. That is, when the hot plate 700 is placed on the table 770 so that the back surface 752 of the outer frame 750 contacts the table 770 as shown in FIG. The height a can be within about 6 cm (preferably about 5-6 cm). Moreover, the height from the table 770 to the cooking surface 712 of the iron plate part 710 can be within 5 cm (preferably about 4 to 5 cm).

  Thus, in this embodiment, the height from the table 770 to the upper end of the outer frame 750 can be within about 6 cm (preferably about 5 to 6 cm). The point where the finger supports chopsticks, forks, etc. is about 5-6 cm above the desktop. Therefore, when using the hot plate 700 on the table 770, hold the chopsticks and fork in the hand to take the food, lift the hand placed on the table 770 and take the food on the hot plate 700, The height to the upper end of the outer frame 750 of the hot plate 700 is the same height. Therefore, the user can feel “easy to use”.

  Moreover, the height from the table 770 to the cooking surface 712 of the iron plate part 710 can be within 5 cm (preferably about 4-5 cm). When placing food on the cooking surface 712 or picking up food prepared from the cooking surface 712, the height of lifting a hand is 5 cm or less. For this reason, since the user's finger can work at a height of about 5 to 6 cm above the desktop, which is a point that supports chopsticks, forks, etc., the user can feel "easy to use". .

  The hot plate 700 of the present embodiment uses heat insulating materials 742 and 744 whose thermal conductivity is lower than the thermal conductivity of still air at normal temperature (20 degrees Celsius plus or minus 15 degrees). For this reason, an air layer for heat insulation is not required between the heat generating material 730 and the outer frame 750, or even if it is provided, it can be lowered. Therefore, the height of the hot plate 700 can be reduced. For this reason, it can reduce that the heating-cooking apparatus hotplate 700 obstruct | occludes a visual field at the time of use, and the feeling of pressure received from the hotplate 700 can be eliminated.

  In addition, if a blower fan for cooling the heat from the heat generating material 730 by air convection is provided, the blower fan forcibly cools the heat transmitted slightly from each member even if the heat insulating materials 742 and 744 are used. By doing so, the cooling efficiency is improved as compared with the conventional cooling that relies on natural convection of air. Therefore, the gap between the members can be reduced, and the height of the hot plate 700 can be further reduced.

  Moreover, since the thickness of the heat source itself can be reduced by using the heating material 730 as a sheet heater, the height of the hot plate 700 can be further reduced.

  Further, the heating material 730 is a sheet-type heater in which the entire upper surface of the flat heater 731 is covered with the covering member 732, thereby protecting the flat heater 731 that is easily broken by an impact, such as a mica heater, with the covering member 732. can do. Therefore, since a heater with a small thickness can be used, the height of the hot plate 700 can be further reduced. Note that the lower surface of the heat generating material 730 is not required to be covered with the covering member 732 because the heat insulating material 744 is provided. Also in this respect, the height of the hot plate 700 can be reduced.

The basic functions of the heat insulating materials 842 and 844 are the same as those of the heat insulating materials 742 and 744 of the third embodiment.

  As shown in FIG. 16, the heat insulating material 843 on which the glass portion 820 is placed has a substantially disk shape. Further, the heat insulating material 844 on which the iron plate portion 810 heat generating material 830 is placed is configured in a donut shape. As shown in FIG. 15, the upper portion of the heat insulating material 844 fits into the housing portion 832 a of the covering material 832 so as to sandwich the flat heater 831 between the ceiling surface of the covering material 832.

As described above, according to the present embodiment, in addition to the effects of the third embodiment, the covering is performed such that the upper portion of the heat insulating material 844 sandwiches the flat heater 831 between the ceiling surface of the covering material 832. By adopting a configuration that fits into the housing portion 832a of the material 832, the gap between the heat generating material 844 and the heat insulating material 844 can be minimized. Therefore, it can be suppressed as much as possible that the heat of the heat generating material 844 is transmitted to a portion other than the iron plate portion 810. For this reason, the heat conduction to the iron plate part 810 can be significantly improved.

  In the present embodiment, no heat insulating material is provided between the side portions of the iron plate portion 810 and the covering material 832 and the outer frame 850, but the present invention is not limited to this example. For example, a heat insulating material may be provided between the side portions of the iron plate portion 810 and the covering material 832 and the outer frame 850.
