Reflected upward toward the other side.

  Further, the infrared rays radiated downward from the lower surface of the carbon fiber portion 46 are reflected upward toward the portions other than the bottom central portion of the rice cooker 2 by the mountain-shaped reflective surfaces 83 and 84 of the reflective bottom plate 42.

  As a result, the entire bottom plate portion 7 of the rice cooker 2, that is, the entire bottom surface of the rice cooker 2 is uniform by the direct infrared rays from the carbon heater 3 and the indirect infrared rays from the reflecting surfaces 83 and 84 of the reflecting bottom plate 42. To be heated.

  In particular, since a part of infrared rays from the carbon heater 3 toward the bottom center portion of the rice cooker 2 is reflected by the reflector 101, heat is more likely to stagnate than the portion other than the center portion of the bottom surface of the rice cooker 2. Only the central portion of the bottom surface that is easily heated is prevented from being intensively heated. Moreover, since the mountain-shaped reflective surfaces 83 and 84 of the reflective bottom plate 42 reflect infrared rays toward the portion other than the bottom center portion of the rice cooker 2, only the bottom center portion of the rice cooker 2 is intensively heated. Is prevented.

  When rice is cooked using the rice cooker 2 in this way, in order to cook rice evenly, the temperature difference between the central portion that is strongly heated at the bottom of the rice cooker 2 and other portions is eliminated, and the entire bottom is made uniform. It needs to be heated.

  The left and right side plate portions 9 on both sides in the conveying direction of the rice cooker 2 are reflected by the reflection surfaces 72 of the left and right reflection side plates 71 supported by the support 43 of the heating unit 41 and the longitudinal member 35 of the apparatus body 16. Heated by infrared rays.

  And from the upper surface opening part of the rice cooker 2 which moves in the conveyance direction while being heated in the heating chamber 15, spilling occurs, and the juice receiving member 61 which is the reflective bottom plate 42 is transmitted through the side plate part 9. The juice falls to the top and spills from the top opening of the rice cooker 2 and at the same time the splashed juice adheres to the reflection side plate 71.

  Thus, the rice cooker 2 is heated by the carbon heater 3 to complete the rice cooking, and the rice cooker 2 after the completion of the rice cooking is sequentially discharged out of the heating chamber 15 from the discharge port 18.

  On the other hand, after the cooking operation, for example, when removing the reflective bottom plate 42 for cleaning, the operator puts his hand into the entrance / exit opening 50, lifts the reflective bottom plate 42 slightly, and pulls it slightly forward to engage. The hole 66 is removed from the engagement receiving portion 55 of the support 43, and then the reflecting bottom plate 42 is tilted so that substantially the entire sliding surface 69 of the guided portion 70 is placed on the inclined guide portion 60. Then, while supporting the reflective bottom plate 42 by hand, the sliding surface 69 of the guided portion 70 is slid on the guide portion 60, and the reflective bottom plate 42 is slid down by its own weight and is taken out from the apparatus main body 16.

  Although not shown, for example, when the juice in the reflective bottom plate 42 may be spilled when the reflective bottom plate 42 is tilted, the operator can catch the engagement hole 66 and the engagement receiving portion 55. After the engagement is released, the longitudinal end portion of the sliding surface 69 of the guided portion 70 (the end on the rising plate portion 64 side facing the upright plate portion 65 while facing the horizontal direction) with the reflection bottom plate 42 held horizontally. Part) is slid on the guide part 60, and the reflection bottom plate 42 is pulled out obliquely downward and taken out from the apparatus main body 16.

  For example, when removing the reflective side plate 71 for cleaning, the operator removes the cover 19 from the apparatus main body 16 and opens the upper surface of the heating chamber 15, and then grips and lifts each reflective side plate 71 by hand. As a result, the engagement between the supported portion 77 and the support portion 39 of the longitudinal member 35 and the engagement between the positioning hole portion 78 and the protruding portion 54 of the support body 43 are released, and the device body 16 is taken out.

  At this time, the carbon heater protection net 81 attached to the protective net attachment hole 80 of the reflection side plate 71 is also taken out from the apparatus main body 16 together with the reflection side plate 71. Further, since the reflecting plate 101 of the infrared reflecting means 100 is attached to the carbon heater protection net 81, it is taken out from the apparatus main body 16 simultaneously with the carbon heater protection net 81.

  And according to such a continuous rice cooking apparatus 1, the strip | belt-shaped reflecting plate 101 of the infrared reflective means 100 reflects the infrared rays radiated | emitted toward the bottom face center part of the rice cooking pot 2 toward the downward side. Therefore, only the central portion of the bottom surface of the rice cooker 2 does not become hot as compared with other portions, and uneven heating is less likely to occur. Therefore, the rice cooker 2 can be appropriately heated and efficiently and continuously heated. I can cook.

  Further, since the reflector 101 of the infrared reflecting means 100 is provided on the carbon heater protection net 81, the configuration is simpler than the case where the reflector 101 is provided separately from the carbon heater protection net 81, and The carbon heater protection net 81 and the reflector 101 can prevent the carbon heater 3 from being damaged.

  Furthermore, since the reflective bottom plate 42 which is the juice receiving member 61 is disengaged and can be detached from the support body 43 by sliding on the guide portion 60, dirt and other deposits attached to the reflective bottom plate 42 can be easily removed. Therefore, the reflecting surface that reflects the infrared rays emitted from the carbon heater 3 is kept smooth, and an efficient reflection state by the reflecting bottom plate 42 can be maintained.

  Further, by lifting the reflection side plate 71 upward, the reflection side plate 71 can be detached from the support body 43 and the elongated member 35 together with the carbon heater protection net 81 and the reflection plate 101. Therefore, the reflection side plate 71, the reflection plate 101, etc. As a result, the reflective surface 72 and the reflective surface 105 are kept smooth as the reflective bottom plate 42, and the reflective side plate 71 and the reflective plate 101 are efficient. The reflection state can be maintained.

  Further, since the support member 43 that supports the carbon heater 3 can be removed from the longitudinal member 49 by lifting the support member 43 upward, it is possible to easily remove deposits such as dirt attached to the support member 43, and Exchange etc. can also be performed easily.

  Further, the engagement hole 66 is engaged with the engagement receiving portion 55 and the guided portion 70 is supported by the guide portion 60, whereby the reflective bottom plate 42 is attached to the support body 43. Since the reflection bottom plate 42 is removed from the support body 43 when the engagement with the engagement receiving portion 55 is released and the guided portion 70 is guided by the guide portion 60, the reflection bottom plate 42 is attached and detached. The deposits on the reflective bottom plate 42 can be more easily removed.

  Further, since the reflecting surfaces 72, 83, 84, and 105 are all formed as smooth surfaces, the reflecting surfaces 72, 83, 84, and 105 can be easily cleaned as well as efficiently reflecting infrared rays. It is possible to easily and appropriately remove deposits attached to the surface.

  Furthermore, since the carbon heater 3 is used as a heating means that is a heat source, when the infrared heating is stopped, unlike the sheathed heater, no residual heat remains in the carbon heater 3 itself. When radiated, heating is performed only by heat, and appropriate heating adjustment can be performed.

  In addition, since the carbon heater protection net 81 and the reflector 101 are disposed below the moving area of the rice cooker 2 and above the carbon heater 3 to cover the upper portion of the carbon heater 3, for example, the object is carbon Even if it falls to the heater 3, the fallen object is received by the carbon heater protection net 81 and the reflector 101, so that it does not collide with the carbon heater 3 and can prevent damage to the carbon heater 3. .

  Further, since the carbon heater 3 is inserted into the carbon heater protection pipe 48, even if a small fallen object passes through the mesh of the carbon heater protection net 81, for example, the carbon heater 3 does not collide with the carbon heater 3. 3 damage can be prevented.

  The shape of the reflecting plate 101 of the infrared reflecting means 100 is not limited to a planar shape, and may be, for example, a V shape or a U shape.

  It should be noted that the reflector 101 is fixed to all the carbon heater protection nets 81 of each heating unit 41 and the reflector 101 is disposed above the carbon heater 3 provided in the heating chamber 15. First, depending on the heating state of the rice cooker 2 being transported, for example, a carbon heater to which the reflector 101 is not fixed, for example, near the inlet 17 side in the heating chamber 15 or near the outlet 18 side in the heating chamber 15. You may make it arrange | position a protective net | network and the infrared rays from the carbon heater 3 may be directly radiated | emitted to the bottom center part of the rice cooking pot 2. FIG.

  Further, the configuration is not limited to the configuration in which the reflection plate 101 is fixed to the carbon heater protection net 81. For example, the configuration in which the reflection plate 101 is detachably provided on the carbon heater protection net 81 may be used.

  Furthermore, for example, a configuration in which one reflector is provided in one carbon heater protection net, a configuration in which three reflectors are provided in one carbon heater protection net, or the like may be used.

  In addition, the shape of the infrared reflecting portion 62 of the reflective bottom plate 42 is not limited to the inverted V shape, and may be a flat shape.

  Furthermore, for example, the heating unit 41 may be configured such that the height position of the heating unit 41 can be adjusted with respect to the rice cooker 2.

  Further, for example, the apparatus main body 16 may have a steaming chamber above the heating chamber 15.

  Furthermore, the heating cooking apparatus is not limited to the continuous rice cooking apparatus 1 and may be, for example, a cooking apparatus that performs cooking other than rice cooking. In this case, a heated container other than the rice cooking pot is used.

  The carbon heater 3 is not limited to a straight longitudinal shape (linear longitudinal shape), but is a curved longitudinal shape (curved longitudinal shape), for example, a disc shape of a round rice cooker (heated container). A circular shape or the like corresponding to the bottom plate portion may be used, and the carbon heater 3 does not necessarily have a longitudinal shape.

  Further, the carbon heater protective body is not limited to the net-plate-shaped carbon heater protective net 81, and may be any one that can catch a fallen object, such as a flat-plate protective plate or a protective sheet.

  Further, the configuration is not limited to the configuration in which the carbon heater protection tube 48 through which the carbon heater 3 can be inserted is fixed to the support body 43. For example, the carbon heater protection tube 48 may be detachably attached to the support body or the like. .
