  In addition, the central portion of the bottom plate portion 73 in the front-rear direction has a left-right longitudinal shape and an inverted V-shaped cross-section that is positioned to be orthogonal to a plurality of carbon heaters 42 (for example, three as a whole) in plan view. The chevron 80 is integrally formed by bending. That is, the bottom plate portion 73 is composed of two flat portions 78 and 79 that are horizontally positioned, and an upwardly convex chevron portion 80 that is located between the two flat portions 78 and 79. Yes.

  A mountain-shaped portion 80 is disposed below the central portion in the longitudinal direction of the carbon heater 42, and the longitudinal direction of the mountain-shaped portion 80 and the longitudinal directions of the plurality of carbon heaters 42 are orthogonal to each other in plan view. And the mountain-shaped part 80 is arrange | positioned under the center part of the front-back direction of the baseplate part 5 of the rice cooker 2 in the heating chamber 3. As shown in FIG. Further, the mountain-shaped portion 80 has a plurality of outside air introduction holes 70 for introducing outside air supplied from the opening 63 side into the heating chamber 3. That is, a slit-like outside air introduction hole 70 is formed in the left-right direction at the longitudinal center portion and the longitudinal inner end side of the apex portion, which is the apex portion of the mountain-shaped portion 80, respectively. The outside air introduction hole 70 is located at least below the center portion of the bottom plate portion 5 of the rice cooker 2.

  And the mountain-shaped part 80 mainly transmits the infrared rays radiated downward from the carbon heater 42 toward the part located above the front end side, which is one end side in the longitudinal direction of the carbon heater 42, in the bottom plate part 5 of the rice cooker 2.

  That is, the inner surface of each side plate portion 16 is located on the side of the left and right side plate portions 7 of the rice cooker 2, and when the infrared rays from the carbon heater 42 are radiated toward the inner surface of each side plate portion 16, the infrared rays are emitted. It is composed of side reflection surfaces 91 that reflect toward the left and right side plate portions 7. The inner surface of the rear plate portion 18 is located behind the side plate portion 7 on the rear side of the rice cooker 2, and when infrared rays from the carbon heater 42 are radiated toward the inner surface of the rear plate portion 18, the infrared rays are converted into the rice cooker 2. The rear reflection surface 92 reflects toward the rear side plate portion 7. The inner surface of the door body 12 is located in front of the side plate portion 7 on the front side of the rice cooker 2, and when the infrared rays from the carbon heater 42 are emitted toward the inner surface of the door body 12, the infrared rays are transmitted to the front side of the rice cooker 2. It is composed of a front reflection surface 93 that reflects toward the side plate portion 7.

  Next, the operation and the like of the cooking device 1 will be described.

  When cooking using the cooking device 1, the operator uses the roller bodies 23, 34, and 39 to put the rice cooker 2 in a closed state into which rice washes, water, and the like have been set and the lid is set. While moving, it is put into the heating chamber 3 through the opened front opening 4.

  Next, the operator rotates the door 12 upward about the shaft 13 to switch from the open state to the closed state, thereby closing the front opening 4 at the door 12.

  At this time, a portion of the heating chamber 3 below the bowl 8 of the rice cooker 2 includes a front door 12 adjacent to the bowl 8, a rear juice receiving member 31 and both side plates adjacent to the bowl 8. Since it is surrounded by the right and left juice receiving members 33 adjacent to the vicinity of the upper part of the portion 7, it becomes a substantially hermetically sealed space that can be filled with hot air so as to be surrounded by hot air.

  When the operator operates the rice cooking start operation portion of the operation setting means, current flows in the inclined carbon fiber portion 44 of the heat generating portion inclined carbon heater 42 and the horizontal carbon fiber portion 44 of the heat generating portion horizontal carbon heater 42, respectively. Flows.

  Then, the carbon fiber portion 44 instantaneously reaches a predetermined temperature (for example, filament temperature: about 1100 ° C.), and infrared rays (mainly mid-infrared rays and far-infrared rays) are directed upward and downward from the upper and lower surfaces of the carbon fiber portion 44, respectively. As a result, the rice cooker 2 is heated.

  At this time, the infrared radiation radiated upward from the upper surface of the carbon fiber portion 44 directly hits the bottom plate portion 5 of the rice cooker 2 as it is, but the infrared radiation radiated downward from the lower surface of the carbon fiber portion 44 is reflected by the reflector 51. After being reflected by (mainly a pair of left and right reflecting members 52), it hits the bottom plate portion 5 of the rice cooker 2. That is, the entire bottom plate portion 5 of the rice cooker 2 is uniformly heated by the direct infrared rays from the carbon heater 42 and the indirect infrared rays from the reflector 51.

  In particular, since infrared rays radiated upward from the inclined carbon fiber portion 44 of the heat generating portion inclined carbon heater 42 are directed obliquely upward on the left and right, compared to other portions other than the central portion of the bottom plate portion 5. Only the central part of the bottom plate part 5 that is easily heated is prevented from being heated intensively.

  Further, since the pair of left and right reflecting members 52 of the reflector 51 has the mountain-shaped portion 80, the infrared rays emitted from the mountain-shaped portion 80 are directed obliquely upward and backward, so that the bottom plate portion 5 of the rice cooker 2 It is prevented that only the central part of is heated intensively.

  Further, the mountain-shaped portion 80 of each reflecting member 52 has an outside air introduction hole 70, and the outside air is introduced from the outside air introduction hole 70 to the vicinity of the center portion of the bottom plate portion 5 of the rice cooker 2 in the heating chamber 3. Only the central part of the bottom plate part 5 of the rice cooker 2 is prevented from being heated intensively.

  That is, the outside air introduction hole 70 of the mountain-shaped portion 80 introduces the outside air into the central portion of the bottom plate portion 5 where the hot air easily drifts and the temperature is likely to be higher than the other portions, thereby causing the hot air to flow, 5 The heating temperature in the central part is made the same as in the other parts, and hot air is induced to the side surface and the upper surface side of the rice cooker 2, and the whole rice cooker 2 is heated and heated, and then the hot air is It is discharged from the exhaust hole 27. The outside air introduction hole 70 is formed at the top of the mountain-shaped portion 80 because the reflecting member 52 also serves as a juice receiving tray, so that the juice spilled from the rice cooker 2 is less likely to spill from the outside air introduction hole 70. .

  When rice is cooked using the rice cooker 2 in this way, in order to cook rice evenly, the temperature difference between the central part and other parts that are likely to be heated and accumulated in the bottom plate part 5 of the rice cooker 2 is eliminated. It is necessary to heat the entire bottom plate portion 5 uniformly.

  On the other hand, the four side plate portions 7 of the rice cooker 2 are heated by infrared rays reflected by the side reflection surface 91, the rear reflection surface 92 and the front reflection surface 93 that cover the periphery of the side plate portions 7.

  Thus, after the rice cooker 2 is heated by the carbon heater 42 and rice cooking is completed and steamed for a predetermined time, the operator opens the front opening 4 of the apparatus main body 11 by switching the door body 12 from the closed state to the open state. Then, the rice cooker 2 is taken out from the heating chamber 3.

  And according to such a heating cooking apparatus 1, the carbon fiber part 44 of the exothermic part inclination carbon heater 42 is arrange | positioned in inclination, and the carbon fiber part 44 of the exothermic part horizontal carbon heater 42 is arrange | positioned horizontally. Therefore, only the central part of the bottom plate part 5 of the rice cooker 2 can be effectively prevented from being heated intensively, and the entire bottom plate part 5 can be heated uniformly, so that the rice cooker 2 is heated appropriately. Can be cooked efficiently.

  In addition, the reflector 51 has a mountain-shaped portion 80 having a longitudinal V-shaped cross section that is positioned so as to be orthogonal to the central portion in the longitudinal direction of the rod-shaped carbon heater 42 in plan view. Since it comprises the side inclined surface 81 and the other side inclined surface 82, it can further prevent that only the center part of the baseplate part 5 of the rice cooking pot 2 is heated intensively. It can heat more appropriately and can cook rice efficiently.

  Furthermore, since the mountain-shaped portion 80 of the reflector 51 has the outside air introduction hole 70 at the top, it is possible to further prevent only the central portion of the bottom plate portion 5 of the rice cooker 2 from being heated intensively. The kettle 2 can be heated more appropriately and the rice cooker 2 can be heated more appropriately, and the rice can be cooked efficiently.

  Moreover, since the reflector 51 has a reflecting member 52 that also serves as a saucer for receiving juice from the rice cooker 2, not only can the infrared rays be reflected by the reflecting member 52, but also the juice blown out from the rice cooker 2, that is, spilled over. You can receive soup.

  Further, since the reflecting member 52 is detachable from the apparatus main body 11, the reflecting member 52 can be removed from the apparatus main body 11 and cleaned, and in particular, the dirt on the reflecting surface of the mountain-shaped portion 80 can be easily removed. it can.

  In addition, since the carbon heater 42 itself is easy to heat and cool, it is hardly affected by the residual heat of the heating means 41 disposed in the heating chamber 3. For example, in the steaming process, the temperature of the heating chamber 3 can be adjusted by turning the power on and off. It is possible to prevent the problem of excessive steaming due to the residual heat in the heating chamber 3.

  In the above embodiment, the carbon fiber portions 44 of the two heat generating portion inclined carbon heaters 42 are arranged in an inclined manner, and the carbon fiber portions 44 of the four heat generating portion horizontal carbon heaters 42 are arranged in a horizontal shape. Although the above-described configuration has been described, it is only necessary that the carbon fiber portion 44 is disposed in an inclined manner with respect to the carbon heater positioned at least below the central portion of the bottom plate portion 5 among the plurality of carbon heaters.

  That is, for example, the structure in which the carbon fiber portions 44 of all six carbon heaters 42 are disposed in an inclined manner may be employed. In the case of this configuration, for example, the carbon fiber portions 44 of the three carbon heaters 42 located on the left side of the heating chamber 3 are arranged in an inclined shape that gradually descends toward the left side, and is positioned on the right side of the heating chamber 3. The carbon fiber portions 44 of the three carbon heaters 42 are arranged so as to be inclined downward gradually toward the right side.

  Further, the inclination angle α of the inclined carbon fiber part 44 may be changed according to the heating conditions, such as which part of the bottom plate part 5 is strongly heated. That is, for example, a configuration in which the carbon heater 42 is attached to the apparatus main body 11 so as to be rotatable about the axis of the carbon heater 42 is also possible.

  The reflector 51 is not limited to the one having the reflecting member 52 and the sensor support member 53. For example, the reflector 51 may not have the sensor support member 53 and may be composed of only one reflecting member.

  Further, the mountain-shaped portion 80 is not limited to a reverse V-shaped cross section, and may be a reverse U-shaped cross section, a semicircular cross section, etc. .

  Further, for example, in the reflecting member 52, a mountain-shaped portion 80 that is integrally formed with the flat portions 78, 79 is formed separately, and the mountain-shaped portion 80 is brought close to the carbon heater 42 and downward from the carbon heater 42. The radiated infrared rays may be scattered and reflected by the peak portion 80 before being scattered.

  Further, for example, a configuration in which the distance between the mountain-shaped portion 80 and the carbon heater 42 can be adjusted, or a configuration in which the inclination angles of the inclined surfaces 81 and 82 of the mountain-shaped portion 80 can be adjusted, etc. For example, the distance between the mountain-shaped portion 80 and the carbon heater 42 and the distance between the carbon heater 42 and the bottom plate portion 5 may be the same.

  Further, an infrared shielding means such as a shielding plate having a V-shaped cross section located between the center portion of the bottom plate portion 5 of the rice cooker 2 and the heating means 41 may be provided.

  Alternatively, the apparatus main body 11 may have a plurality of, for example, three upper and lower heating chambers 3, and a heating unit 41, a reflector 51, and the like may be provided for each heating chamber 3.

  Furthermore, the heat cooking apparatus 1 is not limited to a batch type rice cooking apparatus, For example, the continuous type rice cooking apparatus which cooks rice, conveying the rice cooker 2 with a conveyance means may be sufficient.

  Moreover, what heat-cooks other than rice cooking may be used, for example, In this case, to-be-heated containers other than a rice cooker are used.

  For example, as shown in FIG. 5 and FIG. 6, in order to be able to accurately detect the temperature of the bottom plate portion 5 of the rice cooker 2 with the temperature sensor 54, the bottom plate comes into contact with the bottom plate portion 5 of the rice cooker 2. The shaft-shaped temperature detection member (temperature detection unit) 100 that detects the temperature of the unit 5 may be covered with a cylindrical inner cylinder member 101 and an outer cylinder member 102, respectively.

  The inner cylinder member 101 has a storage portion 103 in which an upper surface opening 99 is formed, and the temperature detection member 100 is stored in the storage portion 103 in a state of being biased upward by a spring 104 that is a biasing member. The outer surface of the temperature detection member 100 is covered with the inner cylinder member 101. The upper end portion of the temperature detection member 100 is inserted into the upper surface opening 99. Further, the upper end portion of the elevating shaft member 107 is fixed to the lower surface of the inner cylinder member 101, and the elevating shaft member 107 is inserted into the shaft insertion portion 108 so as to be movable up and down. Further, interlocking means (not shown) is connected to the lower end portion of the elevating shaft member 107 for elevating the elevating shaft member 107 in accordance with the vertical rotation of the door body 12. When the door body 12 shown in FIG. 5A is in the closed state (when the door is closed), the temperature detection member 100 and the inner cylinder member 101 are in direct contact with the lower surface of the bottom plate portion 5 of the rice cooker 2, and FIG. When the door 12 shown in (b) is in the open state (when the door is open), the temperature detection member 100 and the inner cylinder member 101 are separated from the lower surface of the bottom plate portion 5 of the rice cooker 2.

  The outer cylinder member 102 is fixedly erected on the connecting plate portion 58 of the sensor support member 53, and the outer surface of the inner cylinder member 101 is covered with the outer cylinder member 102. In the vicinity of the outer surface of the outer cylinder member 102, a heating portion inclined carbon heater 42 is disposed. A spring 105, which is a biasing member that biases the inner cylinder member 101 upward, is disposed between the lower surface of the inner cylinder member 101 and the upper surface of the fixing member 106. Furthermore, both the inner cylinder member 101 and the outer cylinder member 102 are formed of a metal material (for example, aluminum or stainless steel) that reflects infrared rays from the carbon heater 42. The temperature detection member 100, the inner cylinder member 101, the outer cylinder member 102, the elevating shaft member 107, the springs 104 and 105, and the like constitute a temperature sensor 54 as temperature detection means.

  And in the structure provided with such a temperature sensor 54, the temperature detection member 100 which contacted the lower surface of the baseplate part 5 of the rice cooking pot 2 in the heating chamber 3 is this temperature at the time of the rice cooking which is the time of the closed state of the door body 12. The detection member 100 is completely covered and covered with the inner cylinder member 101 that reflects infrared rays so that the infrared ray does not directly hit the detection member 100, and the inner cylinder member 101 is covered with the outer cylinder member 102 that reflects infrared rays. Even if the temperature detection member 100 is located in the vicinity of the carbon heater 42, it is not easily affected by infrared rays, so that the temperature sensor 54 can accurately detect the temperature of the bottom plate portion 5 of the rice cooker 2 and the rice cooker 2 is appropriately used. Can be cooked efficiently and can be cooked efficiently. As a related technique, in the configuration including the temperature sensor 54, the carbon fiber portions 44 of all the carbon heaters 42 may be disposed horizontally.
