  On the other hand, the surface facing the heating chamber 3 for heating the rice cooker 2, that is, the inner surface of the apparatus main body 11 and the inner surface of the door body 12 is coated with aluminum, for example, and, like the reflector 51, the bottom plate carbon heater 42 And it is a reflective surface that reflects infrared rays from the carbon heater 101 for the side plate.

  That is, the inner surface of each side plate 16, that is, the left and right inner surfaces of the apparatus main body 11 are located on the sides of the left and right side plates 7 of the rice cooker 2 in the heating chamber 3. The side reflection surface 91 is configured to reflect the infrared rays toward the left and right side plate portions 7 when emitted toward the side. The surface of each concave portion 102 of the apparatus main body 11 is a reflection having a substantially rectangular cross section that reflects mainly infrared rays from the side plate carbon heater 101 toward the lower end side of the side plate portion 7 of the rice cooker 2 in the heating chamber 3. It is a surface. That is, the reflecting surface is formed in a substantially square shape in cross section that opens toward the curved plate portion 7 a side of the side plate portion 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 in the heating chamber 3. When infrared rays are radiated toward the inner surface of the rear plate portion 18, the infrared rays are radiated to 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 7 on the front side of the rice cooker 2 in the heating chamber 3. When infrared rays 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.

  The carbon fiber portions 44 of the carbon heaters 42 and 101 are electrically controlled by a control means (not shown) that can control the amount of heat generated by the carbon heaters 42 and 101, power on / off, etc. via lead wires or the like. An operation setting means (not shown) for setting a heat generation amount and the like is electrically connected to the control means.

  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, a current flows through each carbon fiber portion 44 of the bottom plate carbon heater 42 and the side plate carbon heater 101.

  Then, the carbon fiber portion 44 instantaneously reaches a predetermined temperature (for example, filament temperature: about 1100 ° C.), and infrared rays (mainly middle infrared rays and far infrared rays) are radiated from the carbon fiber portion 44. As a result, the rice cooker 2 is heated. Is done.

  At this time, the infrared rays radiated upward from the upper surface of the carbon fiber portion 44 of the carbon heater 42 for the bottom plate directly hit the bottom plate portion 5 of the rice cooker 2 as they are, but were radiated downward from the lower surface of the carbon fiber portion 44. Infrared rays are reflected by the reflector 51 (mainly a pair of left and right reflecting members 52) and then strike the bottom plate portion 5 of the rice cooker 2.

  Further, infrared rays radiated from the surface of the carbon fiber portion 44 of the side plate carbon heater 101 on the side of the rice cooker 2 directly strikes the curved plate portion 7 a on the lower end side of the side plate portion 7 of the rice cooker 2. Infrared radiation emitted from the surface of the carbon fiber portion 44 of the side plate carbon heater 101 opposite to the rice cooker 2 side is reflected by the concave portion 102 and then strikes the curved plate portion 7a.

  Thus, the entire bottom plate portion 5 of the rice cooker 2 is uniformly heated by the infrared rays emitted from the bottom plate carbon heater 42 and the side plate carbon heater 101.

  At this time, since the pair of left and right reflecting members 52 of the reflector 51 has the mountain-shaped portion 80, the infrared rays radiated from the mountain-shaped portion 80 are directed obliquely upward and backward, so the bottom plate portion of the rice cooker 2 Only the central part of 5 is prevented from being heated intensively.

  Further, the mountain-shaped portion 80 of each reflecting member 52 has an outside air introduction hole 70, and 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.

It can heat more appropriately and can cook rice efficiently.

  Further, since the mountain-shaped portion 80 of the reflector 51 has the outside air introduction hole 70 at the top, only the central portion of the bottom plate portion 5 of the rice cooker 2 can be further prevented from being intensively heated. 2 can be heated even more appropriately, and rice can be cooked efficiently.

  Further, since the reflector 51 has a reflecting member 52 that also serves as a saucer for receiving the juice from the rice cooker 2, not only can the reflecting member 52 reflect infrared rays, but also the juice blown out from the rice cooker 2, that is, the spilled water. 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.

  Furthermore, since the carbon heaters 42 and 101 themselves are easy to heat and cool, the carbon heaters 42 and 101 are not easily affected by the residual heat of the carbon heaters 42 and 101. For example, in the steaming process, the temperature of the heating chamber 3 can be adjusted by turning the power on and off. The problem of excessive steaming due to the residual heat in the heating chamber 3 can be prevented.

  In the above-described embodiment, the configuration in which one side plate carbon heater 101 is provided on each of the left and right sides of the heating chamber 3 has been described. For example, the side plate carbon heater 101 is provided on both the left and right sides of the heating chamber 3. A configuration may be adopted in which a plurality of each is provided.

  Further, for example, the upper surface of the flat carbon fiber portion 44 of the bottom plate carbon heater 42 may be inclined so as to be directed to the portion of the bottom plate portion 5 of the rice cooker 2 to be heated.

  Further, for example, the flat carbon fiber portion 44 of the side plate carbon heater 101 may be positioned in a horizontal or inclined manner in the same manner as the bottom plate carbon heater 42.

  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.
