And from the dry air blower outlet 29 provided in the outer peripheral side of the main body casing 1 with respect to the exhaust blower outlet 28 of the exhaust passage P1 of the exhaust duct 30, along the blowout air from the exhaust blower outlet 28 of the exhaust passage P1. Then, another part of the cooling air from the cooling fan 53 is blown out as dry air so as to flow on the outer peripheral side of the main casing 1. As a result, even if the exhaust from the heating chamber 2 is blown out from the exhaust outlet 28 without being sufficiently diluted, the exhaust stream is discharged from the exhaust outlet 28 to the side of the heating cooker body by the air flow blown out from the dry air outlet 29. In addition, the exhaust flow is diffused from the exhaust outlet 28, and the wall surface can be kept dry. Therefore, it is possible to effectively prevent condensation on the wall surface in the vicinity of the main body of the heating cooker.

  In addition, since the exhaust duct 30 is integrally formed with an exhaust passage P1, a dry air passage P2, and a partition wall 34 that partitions the exhaust passage P1 and the dry air passage P2, the exhaust duct 30 can be connected to a wall near the heating cooker body. The exhaust structure that effectively prevents the dew condensation can be simplified, and the cost can be reduced.

  Further, the exhaust air outlet 28 and the dry air outlet 29 that open toward the front side are each provided with a wind direction control blade 32 that controls the air direction, and the wind direction blown from the rear side toward the front side is forward and oblique. Try to face the direction. As a result, the exhaust blown from the rear side toward the front side on the upper side of the main body of the heating cooker does not directly reach the front side, so that the user can be prevented from directly hitting the exhaust when the door is opened or closed. In addition, with a simple configuration, the air blown from the dry air outlet 29 of the dry air passage P2 of the exhaust duct 30 flows outside along the blowout air from the exhaust outlet 28 of the exhaust passage P1. Can do.

  Further, 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.

  In addition, 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.

  In the above-described embodiment, 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.

  Moreover, in the said embodiment, although 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 An exhaust passage that mixes exhaust gas and blows out from the exhaust outlet, and is provided on the outer peripheral side of the main body casing with respect to the exhaust passage, and another part of the air from the fan follows the blowout air from the exhaust outlet. 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 according to 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.

  In the cooking device of the present invention, healthy cooking can be performed by using superheated steam or saturated steam in a microwave oven or the like. For example, in the cooking device of the present invention, 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. Moreover, when 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. Further, 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. Here, the low oxygen state refers to a state where the volume% of oxygen is 10% or less (for example, 0.5 to 3%) in the heating chamber.

  Although specific embodiments of the present invention have been described, the present invention is not limited to the above embodiments, and various modifications can be made within the scope of the present invention.
