  • the cooling air from the cooling fan 53 flows above the heating chamber 2 along the heater chamber in which the upper heaters 14, 14 for heating the inside of the heating chamber 2 are accommodated, and the exhaust passage P 1 of the exhaust duct 30. , The outside of the heater chamber can be efficiently cooled, and the temperature rise on the upper surface side of the main casing 1 can be suppressed.
  • the cooling air from the cooling fan 53 flows through at least one side surface of the heating chamber 2 after passing through the electrical component chamber S in which the electrical components are disposed, and joins the exhaust passage P1, thereby the electrical component chamber S.
  • the electrical component inside is cooled first, and then the cooling air flows at least along one side of the heating chamber 2, so that the electrical component is cooled by the air before the temperature rises due to the heat of the heating chamber 2.
  • the cooling effect is enhanced and the reliability is improved.
  • the heating cooker using the cooling fan 53 as a fan for sending a part of the wind to the exhaust air outlet or the dry air air outlet has been described. You may apply this invention to the heating cooker using the exhaust fan which sends an air to an air blower outlet.
  • the heating cooker provided with the exhaust duct 30 was demonstrated, not only this but an end is connected to the exhaust port of a heating chamber, a part of air from a fan, and a heating chamber
  • a heating cooker provided with a dry air passage that blows out from the dry air outlet so as to flow on the outer peripheral side of the main casing may be used.
  • Examples of the cooking device of the present invention include not only an oven range using superheated steam but also an oven using superheated steam, an oven range not using superheated steam, and an oven not using superheated steam.
  • healthy cooking can be performed by using superheated steam or saturated steam in a microwave oven or the like.
  • superheated steam or saturated steam having a temperature of 100 ° C. or higher is supplied to the food surface, and the superheated steam or saturated steam adhered to the food surface is condensed to give a large amount of condensation latent heat to the food. So it can efficiently transfer heat to food.
  • condensed water adheres to the food surface and salt and oil are dropped together with condensed water, salt and oil in the food can be reduced.
  • the inside of the heating chamber is filled with superheated steam or saturated steam to be in a low oxygen state, thereby enabling cooking while suppressing food oxidation.
  • the low oxygen state refers to a state in which the volume percentage of oxygen in the heating chamber is 10% or less (for example, 0.5 to 3%).
