The first partition is formed of a light transmissive high heat resistant material.

  With this configuration, the first grill heating means is disposed outside the grill chamber, and the first partition that forms the ceiling of the grill chamber is formed of a light transmissive high heat-resistant material. Heat is transmitted to the grill room by heat radiation due to the light-transmitting effect of the partition wall, and the food placed on the grill pan can be heated and cooked, so that the ceiling part of the grill room is a protrusion etc. while ensuring cooking performance It can be made smooth without any problem, and the cleaning property is remarkably improved.

  According to a second aspect of the invention, in the first aspect of the invention, the first partition that forms the ceiling of the grill chamber is formed of crystallized glass.

  With this configuration, it is possible to greatly improve the reliability of long-term use due to the heat resistance of the crystallized glass while maintaining light transmittance. In addition, crystallized glass has a higher hardness than general metals, so even if it is rubbed during cleaning, it is difficult to be scratched, and a smooth surface can be maintained over a long period of time. Furthermore, since the thermal expansion is much smaller than that of metal, there is less dimensional change when not in use, that is, when it is cold, and when it is in use, that is, when it is hot. Occurrence of squeak noise and the like can be reliably prevented.

  In a third aspect of the invention, in particular, in the first or second aspect of the invention, the first partition that forms the ceiling of the grill chamber is printed with a paint having a light shielding property higher than that of the material.

Can be prevented. The adjustment to make the temperature distribution in the grill chamber more uniform is, for example, by modifying the mold when a hole is formed in the sheet metal member to transmit the radiant heat of the grill heating means to the grill chamber. Although it is necessary to change the hole shape and arrangement, in the case of this configuration, the adjustment can be made inexpensively and easily because it can be performed by changing the printing pattern.

  In addition, the portion outside the grill chamber can be seen through the first partition that forms the ceiling of the grill chamber by printing with a highly light-shielding paint on the portion that does not significantly affect the heating of the cooked food. It can be reduced and looks good, and it is possible to realize a clean and visually elegant grill room.

  In a fourth aspect of the invention, in particular, in any one of the first to third aspects of the invention, the first grill is formed on the opposite side of the first partition that forms the ceiling of the grill chamber in the vicinity of the first grill heating means. A reflector for reflecting the radiant heat of the grill heating means is arranged.

  With this configuration, the heat radiated from the first grill heating unit to the opposite side of the grill chamber is directed toward the grill chamber, and the heat from the first grill heating unit is effectively applied to the food in the grill chamber. It can be added and more efficient heating can be performed.

  According to a fifth invention, in particular, in any one of the first to fourth inventions, in addition to the first grill heating means, second grill heating means for heating the cooked food from below is arranged, and the grill is provided. The dish and the second grill heating means are separated by a second partition that forms the bottom surface of the grill chamber.

  With this configuration, since the fat content from the cooked product does not drip onto the heat generating part of the second grill heating means, it is possible to prevent smoke generation and the like, reduce indoor dirt caused by exhausting outside the main body, and cooked product. Since it is not exposed to the smoke, it does not impair the finished taste. In addition, when removing the dirt adhered to the wall surface of the grill room from the splashes from the cooked food during heating, the second grill heating means is located outside the grill room, so that it is much easier to clean. Since the second grill heating means itself is not soiled, the labor of cleaning can be saved.

  According to a sixth aspect of the invention, in the fifth aspect of the invention, the second partition wall forming the bottom surface of the grill chamber is formed of a light transmissive high heat resistant material.

  With this configuration, for example, by using crystallized glass as a high heat-resistant material, the light transmittance is maintained around the second grill heating means as in the effect around the first grill heating means in the second invention. However, the properties of crystallized glass such as heat resistance, high hardness, and low thermal expansion can improve reliability, maintain a smooth surface for a long period of time, and prevent squeak noise.

  In the seventh invention, in particular, in the fifth or sixth invention, the second partition wall forming the bottom surface of the grill chamber is printed with a paint having a light shielding property higher than that of the material.

  With this configuration, the heat radiation from the second grill heating means for heating the cooked food from below is strong around the second grill heating means, similarly to the effect around the first grill heating means in the third invention. By blocking the excessive portion with this printing, uneven heating can be reduced and the cooked food can be prevented from being burned locally. Adjustment and the like for making the temperature distribution in the grill chamber more uniform can be performed easily and inexpensively by changing the printing pattern.

  In addition, the portion outside the grill chamber can be seen through the second partition wall forming the bottom of the grill chamber by printing with a light-shielding paint on the portion that does not affect the heating of the cooked food. A grill room with reduced quality can be realized.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments. Here, the description order of the embodiments may be different from the order of the invention described above. In some cases, a plurality of inventions are comprehensively described.

(Embodiment 1)
FIG.1 and FIG.2 shows schematic structure of the heating cooker in 1st Embodiment in this invention. However, components that are not necessary for the description of the embodiment are omitted even if they are main components. Hereinafter, it demonstrates using drawing.

  A top plate 2 on which a cooking utensil such as a pan is placed is arranged on the top surface of the main body 1. The heating method of the cooking utensil such as a pan in this embodiment is electromagnetic induction heating, and the top plate 2 is made of a material that is not heated by electromagnetic induction, such as highly heat-resistant crystallized glass, Below the top plate 2, an induction heating coil 3 is provided in close proximity. Here, the heating method of the cooking utensil placed on the top plate 2 is not limited to the electromagnetic induction heating method, and may be, for example, a halogen heater.

  A grill chamber 4 having a substantially box shape and an open front is disposed in the main body 1, and the opening is covered with a grill door 5 that is movable in the front-rear direction. One end of an exhaust tube 6 for discharging smoke generated in the grill chamber 4 to the outside of the main body 1 is connected to the rear portion of the grill chamber 4, and the other end of the exhaust tube 6 is connected to the opening of the top plate 2. It is connected. A grill pan 8 on which the food 7 is placed is housed in the grill chamber 4, and a coating film such as a fluororesin is formed on the surface of the grill pan 8. Improvements are being made.

  A notch 9 formed at the front of the grill pan 8 is fitted to an arm 10 attached to the grill door 5 so that it can move in the grill chamber 4 in conjunction with the movement of the grill door 5. It has become. A sliding member 11 is attached to the rear lower surface of the grill pan 8. When the grill pan 8 is moved, only the sliding member 11 is in sliding contact with the bottom surface 12 of the grill chamber 4, and the coating film on the surface of the grill pan 8 is rubbed. To prevent peeling. The entire grill pan 8 is accommodated in the grill chamber 4 with a clearance from the bottom surface 12 of the grill chamber 4 by the support by the sliding member 11 and the fitting to the arm 10.

  Above the grill chamber 4, a first grill heating means 13 for heating the food 7 from above is disposed, and the first grill heating means 13 and the grill pan 8 form the ceiling of the grill chamber 4. It is isolated by one partition wall 14. That is, the first grill heating means 13 is disposed outside the grill chamber 4. The first partition 14 is made of crystallized glass, which is a light transmissive high heat resistant material.

  As a result, the radiant heat of the first grill heating means 13 passes through the first partition itself made of a light-transmitting material and heats the food 7 on the grill pan 8 for cooking. Since it is not necessary to form a hole or the like for allowing heat to pass through 14, the ceiling portion of the grill chamber 4 can be made a smooth surface without unevenness while ensuring the cooking performance, and the cleaning performance is greatly improved. The problem with the grill configuration is that the ceiling surface is harder to see unless viewed from below, and the heater is in the way, making it difficult to clean and dirt is easily left unattended. As a result, no dirt is accumulated.

  In addition, by forming the first partition wall using crystallized glass, the reliability of long-term use can be greatly improved due to the heat resistance of the crystallized glass. In addition, crystallized glass has a higher hardness than general metals, so even if it is rubbed during cleaning, it is difficult to be scratched, and a smooth surface can be maintained over a long period of time. Furthermore, since the thermal expansion is much smaller than that of metal, there is less dimensional change when not in use, that is, when it is cold, and when it is in use, that is, when it is hot. Occurrence of squeak noise and the like can be reliably prevented.

  Further, the first partition 14, that is, the surface of the crystallized glass on the first grill heating means 13 side is partially printed with a paint 15 having a light shielding property higher than the material of the first partition 14. Yes. There are two types of print locations depending on the purpose. One is a print location 16 for adjusting the heating applied to a portion to be shielded from heat radiation from the heating means, and the other is a print location 17 for blindfolding. By these printings, the portion of the heat radiation from the first grill heating means 13 that heats the cooked food 7 from above is shielded by the printing of this paint to reduce heating unevenness. Can be prevented from being burned. The adjustment for making the temperature distribution in the grill chamber 4 more uniform is, for example, when a hole is formed in the sheet metal member to transmit the radiant heat of the grill heating means to the grill chamber. Although it is necessary to change the hole shape and arrangement by remodeling, this configuration can be done by changing the printing pattern, so that adjustment is inexpensive and easy.

  Further, by printing with a highly light-shielding paint on the portion that does not affect the heating of the cooked food 7, the structure outside the grill chamber 4 is seen through the first partition wall 14 that forms the ceiling of the grill chamber 4. This makes it possible to reduce the appearance of the grill room and improve its appearance.

  A reflector 18 that reflects the radiant heat of the first grill heating means 13 is disposed on the opposite side of the first partition 14. This reflector 18 effectively directs the heat radiated from the first grill heating means 13 toward the opposite side of the grill chamber 4 toward the grill chamber 4 so that the heat from the first grill heating means 13 is effective. It can be added to the cooked food 7 in the grill room 4, and more efficient heating can be performed.

  Below the grill chamber 4, second grill heating means 19 for heating the food 7 placed on the grill pan 8 from below is disposed. The second grill heating means 19 and the grill pan 8 are composed of grills. The chamber 4 is isolated by a second partition wall 20 that forms the bottom surface of the chamber 4. That is, the second grill heating means 19 is disposed outside the grill chamber 4. Similar to the first partition 14, the second partition 20 is formed of crystallized glass, which is a light transmissive high heat resistant material.

  As a result, the fat from the cooked product 7 does not drip onto the heat generating part of the second grill heating means 19, so that it is possible to prevent smoke generation and the like, and the indoor dirt due to the exhaust coming out of the main body 1 through the exhaust pipe 6. Since the cooked food 7 is not exposed to the smoke, the finished taste is not impaired. Further, when removing the dirt adhered to the wall surface of the grill chamber 4 by splashes and the like scattered from the cooked food 7 during heating, the second grill heating means 19 is outside the grill chamber 4 so that it does not get in the way and is cleanable. Since the second grill heating means 19 itself is not dirty, it is possible to save the trouble of cleaning.

  Further, similar to the effect around the first grill heating means 13, the crystallized glass has characteristics such as heat resistance, high hardness, and low thermal expansion while maintaining light transmission around the second grill heating means 19. Therefore, it is possible to improve reliability, maintain a smooth surface for a long time, and prevent squeak noise.

  Furthermore, since it has high hardness and good wear resistance, there is little fear of wear due to the sliding member 11 attached to the rear lower surface of the grill pan 8, and slidability can be maintained.

  Similarly to the first partition 14, the second partition 20, that is, the surface of the crystallized glass on the second grill heating means 19 side is coated with a paint 15 having a light shielding property higher than the material of the second partition 20. Partially printed. As in the case of the first partition 14, printing is provided with a printing portion 21 for adjusting heating and a printing portion 22 for blindfolding, thereby making the temperature distribution in the grill chamber 4 uniform and visually. Quality improvement can be easily achieved at low cost.

  As described above, the present invention can realize a grill function with a simple structure and greatly improved cleaning properties, so that it can be used in a general household kitchen, a commercial kitchen, etc. For example, it can be applied to a tabletop cooking device other than the cooking device.
