- the perspective window portion 21 has a heat ray blocking space CR and a heat insulating space DR.
- the air in the heat ray blocking space CR and the air in the heat insulating space DR function as a heat insulating material.
- the heat ray blocking space CR blocks the transmission of heat rays. Therefore, the heat rays are less likely to reach the front glass plate 211 than in the case where the heat ray reflecting glass 212 is not provided. Therefore, the front glass plate 211 is less likely to generate heat due to absorption of heat rays. That is, the temperature of the front glass plate 211 is lower than that in the case where the heat ray reflecting glass 212 is not provided.

- the cooking cooker 1 can maintain the outer surface temperature of the lid portion 20 at about 80 degrees even if the temperature inside the accommodation space 1A is about 240 degrees.
- the rear glass plate 213 is located on the most accommodation space 1A side of the three glass plates 210.
- the heat ray reflecting glass 212 is located next to the rear glass plate 213. Therefore, the heat ray blocking space CR is located next to the rear glass plate 213.
- the temperature of the front glass plate 211 is lower than, for example, the case where the heat insulating space DR is located next to the rear glass plate 213.
- the cooking cooker 1 can further reduce the rise in the outer surface temperature of the lid portion 20.
- the heat ray reflecting glass 212 has a glass substrate 212A and a heat ray reflecting film 212B.
- the heat ray reflective film 212B is formed on one side of the glass substrate 212A.
- the heat ray reflecting glass 212 is arranged so that the heat ray reflecting film 212B is on the accommodation space 1A side.
- the heat rays are less likely to reach the glass substrate 212A of the heat ray reflecting glass 212 than when the heat ray reflecting glass 212 is arranged so that the heat ray reflecting film 212B is on the opposite side of the accommodation space 1A. Therefore, the glass substrate 212A is less likely to generate heat due to absorption of heat rays.
- the cooking cooker 1 can further reduce the rise in the outer surface temperature of the lid portion 20.

- the cooking cooker 1 can cool the lid portion 20 which has become hot due to the drive of the first blower portion 31, the second blower portion 32, or the grill portion 34. As a result, the cooking cooker 1 can further reduce the rise in the outer surface temperature of the lid portion 20.
- the cooking cooker 1 includes a grill portion 34.
- the cooking device 1 can be cooked by radiant heat.
- the cooking cooker 1 includes a first blower unit 31 and a second blower unit 32. As a result, the cooking device 1 can be cooked with hot air. Further, the heating cooker 1 can cook the object to be heated by using hot air having different heating conditions.
- the cooking cooker 1 includes a microwave supply unit 33.
- the heating cooker 1 can be cooked by microwaves.
- the cooking cooker 1 includes a partition plate 41.

- the heating cooker 1 can efficiently cool the parts to be cooled.
- the intake hole portion 11BA is arranged below the opening 11A.
- the exhaust hole portion 11C is arranged above the opening 11A. Hot air is more likely to rise than cold air. Therefore, the high-temperature air exhausted from the exhaust hole portion 11C is less likely to be taken in from the intake hole portion 11BA. As a result, the heating cooker 1 can cool the parts to be cooled more efficiently. Further, the cooking cooker 1 can efficiently suppress an increase in the temperature of the cooling target component even if there is no space for arranging the intake hole portion 11BA and the exhaust hole portion 11C on the right side and the left side of the opening 11A.
- the cooling fan 40 is located at the same height as the intake hole portion 11BA.

As a result, the heating cooker 1 can cool the parts to be cooled more efficiently.
- the cooling fan 40 is located behind the cooking chamber 10. As a result, the cooling fan 40 can blow air from the rear side of the cooking chamber 10. As a result, the heating cooker 1 can easily guide the blown airflow BF to each of the cooling target parts. As a result, the heating cooker 1 can cool the parts to be cooled more efficiently.
- the cooling fan 40 has a cross flow fan. Compared to a centrifugal blower, a cross-flow fan can take in air over a wide range in the left-right direction (horizontal direction). Therefore, the heating cooker 1 can efficiently take in air from the intake hole portion 11BA and cool the cooling target component more efficiently.
- Centrifugal blowers include sirocco fans.
