FIG. 8 is a perspective view of the internal structure as seen from the left side with the exterior plate 10 removed from the heating cooker 100 according to Embodiment 1 of the present invention. FIG. 9 is a side view of the internal structure as seen from the left side when the exterior plate 10 is removed from the heating cooker 100 according to Embodiment 1 of the present invention. FIG. 10 is a longitudinal sectional view of the internal structure showing a state in which the exterior plate 10 is removed from the heating cooker 100 according to Embodiment 1 of the present invention. FIG. 11 is a longitudinal sectional view of the internal structure showing a state in which the exterior plate 10 is removed from the heating cooker 100 according to Embodiment 1 of the present invention, and is a partially enlarged view of FIG.

  As shown in FIG. 7, on the left side of the cooking device 100, the reflector 43, the connecting rod 44, the first motor 45, the first connecting plate 46, the connecting pin 46a, the reflecting plate holder 47, and the rotating shaft 48 is provided. Further, as shown in FIG. 8, a second connection plate 49 and a second motor 50 are provided on the left side surface side of the cooking device 100. The configuration of each member will be described later.

  As shown in FIG. 9, the light emitting unit 42 includes a light emitting element 41a, a substrate 41b, a condensing part 41c, and a reflecting cylinder 41d. As shown in FIG. 10, the light emitting element 41 a is an illuminating unit that illuminates the inside of the heating chamber 11 through a reflection plate 43 described later, and is configured by a light emitting diode, for example. In addition, the light emitting element 41a is arranged so that the light emitting surface thereof does not face the outside of the wall surface of the heating chamber 11, and is installed so as to emit light upward, for example. In addition, the light emitting element 41 a is disposed, for example, below the lowermost side of the punching hole 40 formed in the side plate 12 b and below at least half of the heating chamber 11 in the height direction. Further, the light emitting element 41a is arranged to be separated from the heating chamber 11 by a side plate 12b. The illumination means for illuminating the heating chamber 11 is not limited to the light emitting element 41a such as the light emitting diode described above, and an organic EL element, a halogen lamp, or the like may be used.

  The substrate 41b is a member for mounting the light emitting element 41a. An electric wire (not shown) is connected to the substrate 41b, and power is supplied from the substrate 41b to the light emitting element 41a via the electric wire. The condensing part 41c is a site | part for collecting the light of the light emitting element 41a. The reflecting cylinder 41d is a member that reflects the light of the light emitting element 41a and diffuses it upward. The reflecting cylinder 41d is processed to reflect light (plating, sputtering, etc.).

  As shown in FIGS. 10 and 11, the reflection plate 43 extends above the light emitting element 41a, specifically, in the direction in which the light is emitted from the light emitting element 41a emitted by the light collecting portion 41c and the reflecting cylinder 41d. Is placed on top. The reflection plate 43 is disposed so as to be inclined so as to reflect the illumination light of the light emitting element 41 a and illuminate the inside of the heating chamber 11. The reflection plate 43 is rotatable about the shaft 43a as a rotation center. For this reason, when it is not necessary to illuminate the inside of the heating chamber 11 during cooking, for example, when the energy saving mode or the like is being executed, the reflecting plate 43 can be moved away from the side plate 12b. Hereinafter, the control of the reflecting plate 43 will be specifically described.

  The heating cooker 100 includes a reflector control unit (not shown) that controls at least one of the position and angle of the reflector 43. The reflector control unit controls the first motor 45 and the second motor 50 based on information such as operation information of the operation unit 14 to change at least one of the position and angle of the reflector 43. For example, when the user operates the operation unit 14 to execute the energy saving mode, operation information of the operation unit 14 is input to the reflector control unit. Then, the reflection plate control means controls the reflection plate 43 so as to move away from the side plate 12b based on this operation information. In this way, the influence of heat and contaminants in the heating chamber 11 on the reflector 43 can be reduced. Therefore, the surface of the reflecting plate 43 can be kept clean for a long period of time, and a decrease in illuminance in the heating chamber 11 can be reduced.

  Note that the above-described reflection plate 43 is moved away, for example, by rotating the reflection plate 43 so that the illumination light of the light emitting element 41a is guided to the exterior plate 10 side, and less affected by the heat in the heating chamber 11. And moving the reflector 43 to the exterior plate 10 side. That is, it means that the reflecting plate 43 is driven so as not to guide the light of the light emitting element 41 a into the heating chamber 11. Further, the illumination light of the light emitting element 41a may be configured to be guided to the heating chamber 11 via the reflector 43. As described above, the light emitting surface of the light emitting element 41a is upward, and the reflector 43 is the light emitting element. It is not limited to being arranged above 41a.

  As shown in FIGS. 10 and 11, the connecting rod 44 is connected to the first motor 45 through the first connection plate 46 by a connection pin 46 a. The length of the connecting pin 46a is longer than the width of the connecting rod 44, and the connecting rod 44 is slidable in the axial direction of the connecting pin 46a. An elongated hole 46b is formed in the connecting portion on the connecting rod 44 side of the first connecting plate 46, and the connecting rod 44 can be slid along the elongated hole 46b. The reflection plate holder 47 is fixed to a rotation shaft 48 that is disposed vertically from the bottom floor plate 38. The output of the second motor 50 described above is transmitted to the rotary shaft 48 via the second connection plate 49, and the reflector 43 can be moved together with the reflector holder 47 in the front-rear direction of the heating cooker 100.

  As shown in FIG. 10, an infrared sensor 39 is disposed closer to the electric chamber 13 than the side plate 12 b on the electric chamber side (the right side of the heating chamber 11). The infrared sensor 39 is temperature detection means for detecting the temperature of the object to be heated. The temperature of the object to be heated placed in the heating chamber 11 is detected through a through hole provided in the side plate 12b.

  The detection information of the infrared sensor 39 is transmitted to a heating control means (not shown) that controls the upper heating unit 16 and the lower heating unit 17. The heating control unit controls the upper heating unit 16 and the lower heating unit 17 based on the detection information of the infrared sensor 39. For example, the heating control unit determines whether or not a predetermined threshold temperature has been exceeded based on the detection information of the infrared sensor 39, and when it exceeds, the operation of the upper heating unit 16 and the lower heating unit 17 is stopped. In the first embodiment, the example in which the infrared sensor 39 is provided as the temperature detection unit has been described. However, the same operation may be performed using another temperature detection unit. Further, the reflector control unit and the heating control unit described above may be configured by the same control unit. That is, the reflector control unit may control the upper heating unit 16 and the lower heating unit 17 based on the detection information of the infrared sensor 39.

  FIG. 12 is a perspective view of reflecting plate 43 of heating cooker 100 according to Embodiment 1 of the present invention, and shows an example in which the surface is concave. FIG. 13 is a perspective view of the reflection plate 43 of the cooking device 100 according to the present invention, and shows an example of a convex surface and a concave surface.

  As shown in FIGS. 12 and 13, the reflector 43 has a shaft 43a. The reflection plate 43 is attached to the reflection plate holder 47 and is rotatable about a shaft 43a. The shaft 43a is disposed horizontally in the longitudinal direction of the reflecting plate 43, and a protrusion 43b connected to the connecting rod 44 is provided at the lower portion of the short side surface. The protrusion 43b is, for example, a spherical protrusion and can be connected to a ball joint. Here, as described above, the connecting rod 44 is connected to the first motor 45 by the connection pin 46 a via the first connection plate 46. For this reason, the output of the first motor 45 described above is transmitted to the connecting rod 44 via the first connecting plate 46, and the reflecting plate 43 can be changed in the vertical direction. The surface shape of the reflecting plate 43 may be a flat portion 43c, a convex portion 43d, a concave portion 43e, or a combination of these types depending on the purpose.

  If the reflecting plate 43 is configured in a concave shape, light can be collected in the heating chamber 11 and the inside of the heating chamber 11 can be illuminated more brightly. Moreover, if the reflecting plate 43 is formed in a convex shape, the inside of the heating chamber 11 can be illuminated in a wide range. Further, if the reflecting plate 43 is configured such that a part of the convex shape is a concave shape, the irradiation light of the light emitting element 41 a is irradiated over a wide area in the heating chamber 11 without using the plurality of reflecting plates 43. In addition, light can be collected in a spot manner.

  As described above, the heating cooker 100 according to the first embodiment of the present invention includes the main body 1 having the heating chamber 11, and the light emitting element 41a disposed inside the main body 1 and separated from the heating chamber 11. A reflecting plate 43 that reflects the illumination light of the light emitting element 41a and illuminates the inside of the heating chamber 11. For this reason, the illumination light of the light emitting element 41a can be introduced into the heating chamber 11 via the reflector, and the inside of the heating chamber 11 can be illuminated as in the conventional case. Therefore, it becomes difficult to be affected by heat and contaminants generated in the heating chamber 11 at the time of cooking, the life of the light emitting element 41a can be prevented from being lowered, and the object to be heated in the heating chamber 11 at the time of cooking can be kept for a long time. Can be illuminated.

  Further, the exterior plate 10 and the rear exterior plate 10a are not formed with exhaust holes for releasing the heat inside the main body. For this reason, the temperature rise of the wall etc. of the peripheral part of a main body installation place can be suppressed. In addition, it is possible to suppress the entry, insertion, and liquid intrusion of foreign matters from the exhaust hole, and it is possible to suppress problems such as a short circuit of electrical components. Furthermore, it is possible to improve safety such as suppression of injuries due to burrs on the exhaust hole end face, failure due to damage to internal wiring of the main body, and suppression of electric shock. In addition, since no exhaust hole is formed, the design can be improved, and the options for the location in the diversifying kitchen can be expanded.

  In addition, the light emitting element 41 a is disposed below half of the heating chamber 11 in the height direction. For this reason, the light emitting element 41a is not easily affected by heat, contaminants, and the like, and the life of the light emitting element 41a can be made longer than before.

  Further, a reflection plate control means for controlling at least one of the position and angle of the reflection plate 43 is provided. For this reason, the illumination light of the light emitting element 41 a can be guided to an arbitrary position in the heating chamber 11. Therefore, when it is not necessary to illuminate the inside of the heating chamber 11, the reflecting plate 43 can be moved away from the wall surface of the heating chamber 11, and the reflecting surface of the reflecting plate 43 can be contaminated, condensed, clouded, discolored, etc. Can be suppressed.

  The reflector control unit may control at least one of the position and the angle of the reflector 43 based on the detection information of the operation unit 14 and the infrared sensor 39. For example, when the user operates the operation unit 14 to execute the energy saving mode in which the lighting inside the heating chamber 11 is not necessary, and the infrared sensor 39 has a temperature equal to or higher than a certain threshold temperature. In other words, the reflection plate control means can move the reflection plate 43 away from the wall surface of the heating chamber 11, and can suppress contamination and discoloration of the reflection surface.

  Moreover, although the example which arrange | positions the 1st motor 45 in the position away from the reflecting plate 43 in order to compactize the periphery of the reflecting plate 43 from the restrictions of the space in the main body 1 was demonstrated, it is not limited to this. For example, if there is room in the space in the main body 1, the output shaft of the first motor 45 may be directly connected to the shaft 43 a of the reflection plate 43 and the first motor 45 may be fixed to the reflection plate holder 47. In this way, it is not necessary to use the connecting rod 44 and the first connection plate 46, so the number of parts of the heating cooker 100 can be reduced.

  In addition, although the example in which the light emitting element 41a is arranged to be separated from the heating chamber 11 by the side plate 12b has been described, it may be arranged to be separated from the heating chamber 11 by another partition. For example, the light emitting element 41a may be provided not on the outside of the side plate 12b but on the outside (back side) of the rear plate 12c.

Modification 1
Modification 1 is an example provided with a plurality of weight detection means (not shown). Here, the plurality of weight detecting means are respectively provided below the mounting plate 28 for detecting the weight of the object to be heated, and support the mounting plate 28 at three or more points.

  The reflection plate control means calculates the weight of the object to be heated and the position of the object to be heated placed on the placement plate 28 based on the detection information of the plurality of weight detection means, and determines the position and angle of the reflection plate 43. Control at least one. For this reason, the reflecting plate control means can control the reflecting plate 43 to illuminate the object to be heated so as to irradiate the light of the light emitting element 41a to the place where the object to be heated is assumed to be placed. Therefore, the user can easily confirm the cooking progress of the object to be heated regardless of the position of the object to be heated.

Modification 2
Modification 2 includes an antenna motor 20 that can rotate forward, reverse, and stop, and rotation control means (not shown) that controls the operation of the antenna motor 20 and changes the electric field intensity distribution in the heating chamber 11. It is an example.

  The rotation control unit controls the position of the antenna 18 based on the detection information of the plurality of weight detection units so that the electric field strength distribution is good at the position where the object to be heated is placed. Therefore, uneven heating of the article to be heated can be suppressed, and the finished state can be made uniform.

  In addition, since the detection information of the plurality of weight detection units is input to the reflection plate control unit, the shape of the reflection plate 43 and the recess 43e (provided in the reflection plate 43 using the movement of the reflection plate 43). 12), spot-like light obtained by condensing can be irradiated to a region where a desired electric field strength is generated. For this reason, a to-be-heated object can be mounted in the place with the favorable heating characteristic according to the cooking characteristic of the to-be-heated object. Note that the rotation control means may control the reflector 43 based on the detection information of the temperature detection means such as the infrared sensor 39.
