- the superheated steam blown out from the plurality of second ceiling steam blowing holes 102 is guided by the heat medium guiding portion 391 provided on the left and right side surfaces, and is heated on the rack 324 placed on the upper tray 302. Efficiently supplied to the underside of the object 390.
- the superheated steam blown from the side steam outlet 322 is branched obliquely downward and obliquely upward. .
- overheating blown obliquely upward from the side steam outlet 322 The steam is supplied to the upper side of the heated object 390 on the rack 324 placed on the lower tray 301, while the superheated steam blown obliquely downward from the side steam outlet 322 is placed on the lower tray 301. It is supplied to the lower side of the heated object 390 on the placed rack 324.
- the steam The superheated steam from the heating device 50 is supplied to the space between the side steam outlet 322 and the trays 301 and 302 via the steam supply passage 323 that connects the steam heating device 50 and the side steam outlet 322. .
- the superheated steam supplied through the first ceiling steam outlet hole 101 and the second ceiling steam outlet hole 102 on the ceiling side is supplied to the heated object 390 placed on the upper tray 302.
- the superheated steam supplied through the side steam outlet 322 provided on the side surface of the cooking chamber 320 is supplied to the object to be heated 390 placed on the lower tray 301.
- the tray structure of the stage can be cooked with good finish without uneven heating.
- the heating cooker of the third embodiment has the same effect as the heating cooker of the first embodiment.
- the superheated steam obtained by superheating the steam generated by the steam generating device 40 by the steam heating device 50 as an example of the heat medium supply unit is used in the cooking chamber 20.
- the steam generator 40 does not generate steam, but the air in the cooking chamber 20, 220, 320 is sucked from the suction port 25 by the blower fan 28, and then sent to the steam heating device 50 again.
