The illuminator 21 is attached to the heat-insulating metal plate 12c with a heat-shielding metal plate 23 interposed between the illuminator 21 and the metal plate 12c. Specifically, the illuminators 21 a and 21 b are each attached to the metal plate 12 via the metal plate 23. The metal plate 12 is of a size that protrudes somewhat from the outer periphery of the illuminators 21a and 21b. The metal plate 12 has a flange 23c bent outward from the upper edge of the metal plate 12, and a flange 23d bent outward from the front edge of the metal plate 12.

  Reference is now made to FIG. FIG. 5 is an exploded perspective view around the side wall on the other side in the longitudinal direction of the heating chamber. In order from the side wall 5c side of the heating chamber 5, the cover part 27, the translucent member 25, the heat insulating metal plate 12c, the heat shielding metal plate 23, and the illuminator 21 are arranged in this order.

  The heat insulating metal plate 12c includes a hole 12ca through which light emitted from the illuminator 21 passes, and a hook 12cb formed by bending outward from the front end and the rear end of the hole 12ca. The metal plate 12c has a flange 12cc bent inward from the upper edge and the lower edge. The side wall 5c of the heating chamber 5 has a flange 5cc bent outward from the upper and lower edges of the side wall 5c.

The cover part 27 is attached to the front upper part of the side wall 5c on the other side of the heating chamber 5, for example, by caulking. The translucent member 25 has a rectangular shape that is longer in the vertical direction than in the front-rear direction in a side view.

  Reference is now made to FIGS. FIG. 7 is a front perspective view of the cover portion to which the translucent member is attached. FIG. 8 is a front perspective view of the cover part with the translucent member removed. The cover portion 27 has a first stop portion 27g cut and raised outward from the center portion in the height direction of the outer surface of the cover portion 27. The first stopper 27g has an L-shaped cross section and extends in the vertical direction, and has two protrusions on the inner side. Further, the cover portion 27 has a semicircular protrusion 27h in a side view. A part of the rear side surface of the translucent member 25 is in contact with the first stopper 27g, and a part of the front side surface of the translucent member 25 is in contact with the protrusion 27h. As described above, the translucent member 25 is engaged with the first stoppers 27g and the protrusions 27h, so that the movement of the translucent member 25 in the front-rear direction is restricted.

  Moreover, the cover part 27 has two 2nd stop parts 27k bent by the nail | claw shape toward the outer side from the upper end. The cover part 27 has a third stopper part 27m cut and raised outward from the front lower part of the outer surface. The third stopper 27m has an L-shaped cross section and extends in the front-rear direction, and has a protrusion on the inside. Furthermore, the cover part 27 has the 4th stop part 27n bent in the shape of a nail | claw toward the outer side from the lower end center part. The upper side surface of the translucent member 25 abuts against the two second stoppers 27k, and the lower side surface of the translucent member 25 abuts the third stopper part 27m and the fourth stopper part 27n. Thereby, the vertical movement of the translucent member 25 is restricted.

  The translucent member 25 attached to the cover portion 27 can be disengaged from the protrusion 27h by being pulled outward (X direction). Thereby, the translucent member 25 can be slid forward, and the translucent member 25 can be removed from the cover portion 27. Further, when the translucent member 25 is attached to the cover portion 27, the rear end of the translucent member 25 is pressed against the first stopper 27g, and the front end of the translucent member 25 is pushed inward. It can be fitted with the protrusion 27h. Further, since the translucent member 25 is pressed against the flat portions 27c and 27d by the two projections formed inside the first stopper 27g and the projection inside the third stopper 27m, the translucent member 25 is fixed to the cover portion 27.

  The cover portion 27 is a metal plate for attaching the light transmissive member 25. The cover portion 27 has concave portions 27a and 27b protruding outward. The concave portion 27a and the concave portion 27b are arranged at an interval in the vertical direction. A flat portion 27c is provided on the bottom (outer side) of the recess 27a. A hole 27e is formed in the flat portion 27c. Accordingly, a flat region is formed around the hole 27e by the flat portion 27c. The light from the illuminator 21a passes through the hole 27e.

  Moreover, the flat part 27d is provided in the bottom (outer part) of the recessed part 27b. A hole 27f is formed in the flat portion 27d. Therefore, a flat region is formed around the hole 27f by the flat portion 27c. The light from the illuminator 21b passes through the hole 27f.

  Reference is now made to FIG. FIG. 9 is a cross-sectional view around the illuminators 21a and 21b. The side wall 5c of the heating chamber 5 has a hole 5ca for irradiating the light from the illuminator 21 into the heating chamber. Further, the side wall 5c has a bent portion 5cb around the hole 5ca, in which the side wall 5c is cut and raised outside the hole 5ca. The bent portion 5cb reduces radio waves leaking from the inside of the heating chamber 5 to the outside of the hole 5ca.

  The flat portions 27c and 27d of the cover portion 27 are in contact with the translucent member 25 outside the bent portion 5cb. Therefore, the bent part 5cb of the side wall 5c and the translucent member 25 do not contact directly. Further, the flat portions 27c and 27d and the translucent member 25 are in contact with each other at the surfaces. Thereby, it can prevent that the translucent member 25 is damaged by the bending part 5cb by a vibration, or is cracked. Further, since the surfaces are in contact with each other, the leakage of steam from between the flat portions 27c and 27d and the translucent member 25 can be significantly reduced. Furthermore, since the translucent member 25 is not scratched, the vapor in the heating chamber 5 does not leak through the hole 5ca from the gap between the scratches.

  A cooling fan (not shown) is disposed in the machine room below the heating chamber 5. On the metal plate 12c, the cooling air from the cooling fan (not shown) flows from below to above, so that the cooling air flows through the back of the LED illuminators 21a and 21b. Therefore, since the LED elements 21aa and 21ba are cooled from the back side of the substrate, the influence of heat from the heating chamber 5 can be reduced.

  Moreover, the translucent member 25 and the cover part 27, and the metal plate 12c are arrange | positioned by non-contact, respectively. Since there are gaps between the translucent member 25 and the cover part 27 and the metal plate 12c, it is possible to reduce the conduction of heat from the translucent member 25 and the cover part 27 to the metal plate 12c. Thereby, the influence of the heat | fever to LED element 21aa and 21ba can be reduced.

  The heating cooker 1 includes a heating chamber 5, a side wall 5c that defines one surface of the inner surface of the heating chamber 5, and a hole 5ca formed in the side wall 5c. Moreover, the heating cooker 1 is provided with the cover part 27 which is arrange | positioned on the outer side of the hole 5ca, and has the hole 27e which overlaps with the hole 5ca, and the flat part 27c formed along the circumference | surroundings of the hole 23e. Furthermore, the heating cooker 1 faces the hole 5ca and the hole 27e, passes through the translucent member 25 attached to the cover portion 27 in contact with the flat portion 27c, and the heating chamber through the hole 5ca, the hole 23e, and the translucent member 25. 5 is provided, and at least one of light emission to 5 and light reception from the heating chamber 5 is performed, and an illuminator 21 disposed outside the cover portion 27 is provided. Further, the side wall 5c has a bent portion 5cb cut and raised to the outside around the hole 5ca. From this configuration, the following effects can be obtained.

  Around the hole 5ca opened in the side wall 5c, there is a bent portion 5cb cut and raised toward the outside of the side wall 5c, so that radio waves in the heating chamber 5 leak out of the heating chamber 5 from the hole 5ca. Can be prevented. In addition, the translucent member 25 is disposed through the cover portion 27 instead of directly contacting the translucent member 25 to the hole 5 ca formed in the side wall 5 c of the heating chamber 5. Thereby, when the inside of the heating chamber 5 vibrates, it can prevent that the bending part 5cb which vibrates damages the translucent member 25. FIG. Moreover, since the flat part 27c of the cover part 27 and the translucent member 25 are in contact with each other, the translucent member 25 is hardly damaged. Further, since the translucent member 25 is in contact with the cover portion 27, it is possible to prevent the steam from leaking out of the heating chamber 5 through the hole 5ca.

  The metal plate 12c arrange | positioned on the outer side of the translucent member 25 is provided, and the illuminator 21 is attached to the metal plate 12c. Since the heat insulation effect can be obtained by the metal plate 12 c, the ambient temperature of the illuminator 21 can be lowered than the temperature in the heating chamber 5. Thereby, it can reduce that the illuminator 21 receives a thermal influence.

  A metal plate 23 is provided between the illuminator 21 and the metal plate 12 c, and the illuminator 21 is attached to the metal plate 12 c via the metal plate 23. By further including a metal plate 23 different from the metal plate 12c, a heat shielding effect can be obtained. Thereby, it can further reduce that the illuminator 21 receives a thermal influence.

  The side wall 5c has two holes 5ca, and the cover portion 27 has two holes 27e and 27f and two flat portions 27c and 27d corresponding to the two holes 5ca, respectively. The translucent member 25 is disposed so as to face the two holes 5ca and the two holes 27e and 27f and to contact the two flat portions 27c and 27d. Thereby, since the one translucent member 25 is arrange | positioned with respect to the two holes 27e and 27f of the cover part 27, the magnitude | size of the translucent member 25 is larger than the two holes 27e and 27f, and a cover The size can be easily attached to the portion 27.

  The cover portion 27 includes a first stop portion 27g and a protrusion 27h that restrict movement of the translucent member 25 in the width direction (Y-axis direction), and a second stop portion 27k that restricts movement of the translucent member 25 in the height direction. And a third stop portion 27m. With these configurations, the translucent member 25 can be appropriately attached to the cover portion 27.

  The present disclosure is not limited to the above embodiment, and can be modified as follows.

  In the said embodiment, you may arrange | position optical devices other than the illuminator 21 as a light emitting element. For example, an imaging element or a light receiving element may be arranged as an optical device. Moreover, you may arrange | position these combinations. Examples of the image sensor include a CMOS image sensor and a CCD image sensor. An example of the light receiving element is an infrared temperature sensor.

  In addition, it can be made to show the effect which each has by combining suitably any embodiment among the said various embodiment and modifications.
