  At both ends in the longitudinal direction of each second rod-shaped portion 93, protruding insertion end portions 94 that are removably inserted into the protective mesh mounting hole 80 of the reflection side plate 71 are outward from the annular portion 91. It is formed to protrude. The carbon heater protection net 81 is detachably attached to the both reflection side plates 71 by inserting these insertion end portions 94 into the protection mesh attachment holes 80 of the both reflection side plates 71.

  As a result, even if a fallen object falls toward the carbon heater 3, damage due to direct contact with the glass tube portion 45 of the carbon heater 3 is prevented.

  Moreover, as shown in FIGS. 2 and 8 to 10, the continuous rice cooker 1 is disposed in the vicinity of the conveyance start end side of the conveyance means 31, that is, in the vicinity of the inlet 17 of the heating chamber 15. There is provided an entrance gate 101 which is a reverse gate-shaped deformed container stop for stopping the rice cooker 2 by abutting against the unusually shaped rice cooker 2 which is greatly deformed downward. Incidentally, the entrance gate 101 can be taken in and out of the apparatus main body 16 like the reflection side plate 71 and the like.

  The entrance gate 101 has a rectangular contact plate portion 102 that is elongated in a direction orthogonal to the transport direction and is horizontal.

  The rising plate portion 103 rises from both longitudinal ends of the contact plate portion 102, and is supported on the upper outer surface side of the rising plate portion 103 by a support portion 39 of the longitudinal member 35 of the apparatus main body 16 so as to be detachable. A plate-like supported portion 104 is fixed. Each of the left and right rising plate portions 103 includes an upper inclined plate 103a positioned on the inner side toward the upper end, a lower inclined plate 103b positioned on the inner side toward the lower end, and the upper inclined plate 103a and the lower inclined plate 103b.

  Further, a protruding plate portion 105 protrudes downward from an end portion of the contact plate portion 102 on the downstream side in the transport direction. The protruding plate portion 105 is provided with a mounting step portion 106 that is mounted on the mounting portion 110 of the apparatus main body 16.

  Then, as shown in FIGS. 9 and 10, for example, when the irregular shaped rice cooker 2 in which the bottom plate portion 7 is greatly deformed downwardly is placed and conveyed by the chain 32 of the conveying means 31, The bottom surface of the bottom bulge 7 of the rice cooker 2 is in contact with the contact plate 102 of the entry gate 101, and movement of the rice cooker 2 in the transport direction is restricted by this contact.

  As a result, the chain 32 of the conveying means 31 slides with respect to the bowl portion 10 of the rice cooker 2, and stops in a state where the irregularly shaped rice cooker 2 is in contact with the contact plate portion 102. Thus, the entrance gate 101 can stop the deformation of the deformed rice cooker 2 into the heating chamber 15, and the deformed rice cooker 2 moves in the heating chamber 15. The bottom plate portion 7 swelled downward contacts the carbon heater protection net 81 and further prevents damage caused by pressing the carbon heater 3 from above. In the case of the rice cooker 2 that can pass through the entrance gate 101, even if the bottom plate portion 7 is deformed and swells downward by being heated by the carbon heater 3 in the heating chamber 15, the carbon heater 3 is damaged. The inside of the heating chamber 15 is transported without being deformed.

  Of the constituent members of the continuous rice cooker 1, at least the reflective bottom plate 42, the support body 43, and the reflective side plate 71 are formed of a metal material (for example, aluminum or stainless steel) that reflects infrared rays from the carbon heater 3. 2 is the width dimension of one heating unit 41, and b in FIG. 2 is the width dimension of one reflection side plate 71.

  Next, the operation of the continuous rice cooker 1 will be described.

  For example, a plurality of rice cookers 2 in which rice washing, water, and the like are introduced into the pot body 5 and the lid body 6 is set are sequentially put into the heating chamber 15 from the input port 17 while being in contact with each other. Then, the plurality of rice cookers 2 are moved in the moving direction in the heating chamber 15 by the conveying means 31 in the conveying direction.

  The movement of the rice cooker 2 may be tact movement (intermittent operation) that stops every elapse of a predetermined time, or may be continuous movement that continues to move. Further, for example, the irregular rice cooker 2 in which the bottom plate portion 7 is greatly deformed in a downward bulging state is stopped by contact with the entry gate 101. In this case, the operator removes the irregular rice cooker 2 from the conveying line.

  And the normal-shaped rice cooker 2 thrown in in the heating chamber 15 is heated by the plurality of carbon heaters 3 positioned below during the movement in the heating chamber 15, and the cooked rice that is cooked is heated. Done continuously.

  That is, when power is supplied from the power source to the carbon fiber portion 46 of each carbon heater 3 of each heating unit 41 and the current flows, the carbon fiber portion 46 instantaneously reaches a predetermined temperature (for example, filament temperature: about 1100 ° C.). A large amount of infrared rays (mainly mid-infrared rays and far-infrared rays) are radiated upward and downward from the carbon fiber portion 46, and 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 46 of each carbon heater 3 directly hits the bottom plate portion 7 of the rice cooker 2 as it is, but the infrared radiation radiated downward from the lower surface of the carbon fiber portion 46. Is reflected upward by the reflecting surface 62 of the reflecting bottom plate 42 and then hits the bottom plate portion 7 of the rice cooker 2. That is, the entire bottom plate portion 7 of the rice cooker 2 is uniformly heated by the direct infrared rays from the carbon heater 3 and the indirect infrared rays from the reflection surface 62 of the reflection bottom plate 42.

  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 part 66 is removed from the engagement receiving part 55 of the support body 43, and then the reflective bottom plate 42 is tilted so that substantially the entire sliding surface 69 of the guided part 70 is placed on the inclined guide part 60. Then, while the reflective bottom plate 42 is supported by hand, the sliding surface 69 of the guided portion 70 is slid on the guide portion 60 while the reflective bottom plate 42 is slid down by its own weight, and is taken out from the apparatus main body 16 ( (See FIG. 4).

  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 engages with the engagement portion 66 and the engagement receiving portion 55. After releasing the alignment, the longitudinal end portion of the sliding surface 69 of the guided portion 70 (the end portion on the rising plate portion 64 side facing and spaced from the standing plate portion 65 while holding the reflective bottom plate 42 horizontally) ) Is slid on the guide portion 60, and the reflection bottom plate 42 is pulled out obliquely downward and taken out from the inside of 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.

  And according to such a continuous rice cooker 1, the infrared rays (radiant heat) from the carbon heater 3 are directed to the bottom plate portion 7 of the rice cooker 2 so that the entire bottom plate portion 7 of the rice cooker 2 is uniformly heated. Therefore, the rice cooking pot (heated container) 2 can be heated appropriately and can be cooked efficiently and continuously (heat cooking).

  Further, 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, the adhered matter such as dirt attached to the reflective bottom plate 42 can be easily obtained. Therefore, the reflecting surface 62 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.

  Furthermore, since the reflection side plate 71 can be removed from the support body 43 and the elongated member 35 by lifting the reflection side plate 71 upward, deposits such as dirt attached to the reflection side plate 71 can be easily removed. Thus, the reflecting surface 72 is kept smooth, and an efficient reflection state by the reflecting side plate 71 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 engaging portion 66 is engaged with the engaging receiving portion 55 and the guided portion 70 is supported by the guiding portion 60, whereby the reflective bottom plate 42 is attached to the support body 43 and is engaged with the engaging portion 66. Since the reflection bottom plate 42 is removed from the support body 43 when the engagement with the receiving portion 55 is released and the guided portion 70 is guided by the guide portion 60, the reflection bottom plate 42 can be easily attached and detached. Thus, the deposit on the reflective bottom plate 42 can be more easily removed.

  Further, since both the reflecting surface 62 of the reflecting bottom plate 42 and the reflecting surface 72 of the reflecting side plate 71 are formed as smooth surfaces, not only can infrared rays be efficiently reflected, but also the cleaning can be easily performed. , 72 can be removed easily and appropriately.

  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 is provided below the moving area of the rice cooker 2 and above the carbon heater 3 and covers the upper portion of the carbon heater 3, for example, an object is directed to the carbon heater 3 for some reason. Even if it falls, the fallen object is received by the carbon heater protection net 81, so that it does not collide with the carbon heater 3 and damage to the carbon heater 3 can be prevented.

  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.

  Moreover, since the entrance gate 101 which stops this irregular-shaped rice cooker 2 by contact | abutting with the bottom plate part 7 of the deformed irregular-shaped rice cooker 2 is provided, the deformed irregular-shaped rice cooker 2 is conveyed, and the downward bulging form is carried out. This prevents the bottom plate portion 7 from colliding with the carbon heater 3 and prevents the carbon heater 3 from being damaged. The entrance gate 101 disposed near the inlet 17 of the heating chamber 15 not only prevents the deformed rice cooker 2 from being introduced into the heating chamber 15, but also prevents the entrance gate 101. By forming the contact plate portion 102 and the rising plate portion 103 close to the bottom plate portion 7 and the side plate portion 9 of the rice cooker 2, the rice cooker 2 faces the entrance gate 101 and the entrance gate 101 When located above, the inflow of outside air into the heating chamber 15 and the outflow of hot air in the heating chamber 15 are also prevented.

  The reflective bottom plate 42, which is the juice receiving member 61, is not limited to the one having the planar reflective surface (smooth surface) 62 positioned along the horizontal plane. For example, as shown in FIGS. It may have planar reflecting surfaces (smooth surfaces) 83 and 84 that are inclined with respect to the horizontal direction so as to have a mold shape.

  A top portion 85, which is a connecting portion between the reflection surface 83 on one side and the reflection surface 84 on the other side, is a longitudinal horizontal side portion along the conveying direction of the rice cooker 2, and is located at the center in the longitudinal direction of the carbon heater 3. It is arranged below.

  And the left reflective surface 83 which is one side reflects the infrared rays from the carbon heater 3 obliquely upward toward the left end side which is one end side of the bottom plate portion 7 of the rice cooker 2. The right reflecting surface 84 which is the other side reflects the infrared rays from the carbon heater 3 obliquely upward toward the right end side which is the other end side of the bottom plate portion 7 of the rice cooker 2.

  By doing in this way, when the rod-shaped carbon heater 3 is arrange | positioned in the lower part of the heating chamber 15, in the longitudinal direction of the carbon heater 3, there exists a possibility that temperature may become high compared with another part in the center part. On the other hand, the direction in which the infrared rays radiated downward from the carbon heater 3 are reflected by the reflecting surfaces 83 and 84 in an oblique direction, that is, toward the curved plate portion 8 side of the rice cooker 2, and as a result, moves. Only the central portion along the conveying direction of the bottom plate portion 7 of the rice cooker 2 is prevented from being intensively heated, and the entire bottom plate portion 7 of the rice cooker 2 is thereby heated more uniformly.

  The reflective bottom plate 42 shown in FIGS. 11 to 13 is a plate-shaped reflective plate 86 having an inverted V-shaped cross section placed on the bottom 63 of the reflective bottom plate 42 shown in FIG. is there. For example, although not shown, the reflector 86 may have a mountain shape having an inverted U-shaped cross section, a semicircular cross section, or the like.

  Further, for example, a configuration in which the heating unit 41 can adjust the height position with respect to the rice cooker 2 may be used.

  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. .
