The casing 1 is provided with a blowing means 5 that is a fan for forced circulation for blowing air to the interior 1 a and is driven by an external motor 6.

  A boiler 7 that generates superheated steam and water supply means 8 that is a pump that feeds water from below the boiler 7 are provided outside the housing 1. The water supply means 8 is configured to be supplied with water from a tank 9. The superheated steam generated in the upper part of the boiler 7 is sent to the interior 1 a through the steam induction duct 10, and the interior circulation suction port 11 is configured at the outlet of the steam induction duct 10. On the outlet side of the air blowing means 5 provided at the rear part of the internal circulation suction port 11, a follower heating means 12 as a heater is configured. The housing 1 is provided with a plurality of internal circulation outlets 13 for circulating the air blown from the air blowing means 5 to the interior 1a. 14 is a boiler heater provided in the boiler 7, and 15 is a plurality of guide plates configured in the boiler 7.

  As an operation according to this configuration, first, water is sent from the tank 9 to the boiler 7 by the water supply means 8. Inside the boiler 7, when water touches the boiler heater 14, it is heated and begins to evaporate. The steam is heated while rising as indicated by an arrow A along the plurality of guide plates 15 inside the boiler 7 to become superheated steam, and is guided to the steam induction duct 10. When the superheated steam exits from the steam induction duct 10, it is sucked in by the blower means 5 from the internal circulation suction port 11 as indicated by arrow B, heated by the follower heating means 12, and then heated in a plurality of internal circulation airflows as indicated by arrow C. It is sent to the inside 1a from the outlet 13, and the inside 1a is filled with superheated steam. Air and excess steam in the chamber are expelled from the opening 2 below the side surface and cooled inside the cooling duct 3. The condensed water at this time is collected in the lower water tray 4.

  Next, the effect will be described. Since superheated steam is lighter than air, it is located above the interior 1a. If an exhaust opening is provided at the upper side, the steam escapes, and air remains in the interior 1a and the superheated steam cannot be used well, but the interior 1a is filled with the superheated steam by providing the opening 2 below the side surface. Can do. Moreover, since the superheated steam that has entered from the steam induction duct 10 is immediately applied to the follow-up superheating means 12 by the blower means 5, it is possible to realize a stable cooking state with little fluctuation of the internal temperature. Furthermore, the cooling duct 3 is safe because heated air and steam are not directly blown out of the warehouse.

(Example 2)
FIG. 2 shows the configuration of the second embodiment. In the figure, a temperature detection means 20 is provided inside the steam induction duct 10, a temperature detection means 21 is provided on the wall surface below the interior 1 a, and a temperature detection means is provided in the vicinity of the circulation circulation inlet 11 on the suction side of the blower means 5. 22 and a temperature detecting means 23 at the position of the opening 2 below the side surface, and temperature detecting means at a total of four locations. Since other configurations are the same as those of the first embodiment, the description thereof is omitted.

  As an effect of providing these four temperature detection means 20 to 23, the generated steam temperature according to the cooking content can be detected by the temperature detection means 20, and the warehouse wall temperature for preventing condensation on the warehouse wall is the warehouse wall temperature. The temperature detecting means 21 provided at the lowest position can detect the temperature of the steam stirred in the warehouse, and the temperature detecting means 22 can detect the temperature of the steam. This can be confirmed by the temperature detecting means 23.
