- the mixing means 55 is provided with a louver 103 for regulating the wind direction downstream of the baffle plate 101.
- a louver 103 for regulating the wind direction downstream of the baffle plate 101.
- the outside air is sucked by the blowing means 51 to generate the cooling air C, and each heat flow (main heat flow) is first generated in the upper heat storage chamber 53 above the heating chamber 23.
- the first heat flow passage 57 through which the main heat flow Q flows is cooled by the heat flow around the heating room q whose temperature is lower than the main heat flow Q, and the heat flows are mixed.
- the main heat flow Q is cooled. Furthermore, it is located upstream of the exhaust port 29.
- the cooling air CA 1 is mixed with the mixed heat flow (Q + q) of the upper heat reservoir 53 by the mixing means 55, and the high-temperature air and the cooling air are efficiently separated by the small blowing means 51. Mixing becomes possible, and the mixing part volume can be reduced. For example, when the heating chamber is heated to 300 ° C., the inside of the third heat flow passage 61 becomes hot air exceeding 100 ° C., but the cooling air CA from the first cooling air passage 79 Due to 1, the air is exhausted from the exhaust port 29 as hot air of about 60 ° C.
- the blowing means for sucking the outside air to generate the cooling air, and the upper heat storage chamber for collecting each heat flow above the heating chamber And a mixing means arranged upstream of the exhaust port for mixing the heat flow in the upper heat storage chamber and the cooling air, so that high-temperature air and cooling air can be efficiently mixed with a small amount of blowing means.
- the volume of the mixing section can be reduced. Therefore, it is not necessary to secure the exhaust port over the entire width of the cooker, and the heating chamber and the heating operation unit can be arranged above. As a result, a built-in type cooking device excellent in workability and operability can be obtained.
