  As shown in FIG. 11, a heating chamber 112 that houses the tray 108 is disposed on the left side of the front panel 110 of the casing 101. Further, on the right side of the front panel 110, a drawer-type front operation panel 280 having an operation unit 280a that also serves as a display unit is arranged. This front operation panel 280 is for operating the heating chamber 112 and is supported so as to be rotatable in the front-rear direction with the lower end side as an axis. When the heating chamber 112 is not used, the front operation panel 280 is housed in the casing 101.

  FIG. 12 is a schematic plan view showing the arrangement of the main part of the IH cooking heater 100E. In FIG. 12, the lower side is the front side, and the upper side is the rear side.

  As shown in FIGS. 11 and 12, the water tank 430 (see the schematic diagram in FIG. 15) is detachable from the front side of the casing 101. The water stored in the water tank 430 is supplied to the steam generator 122 via a pump 199 as shown in FIG. The front operation panel 280 and the drive circuit block 210 constitute a control circuit for controlling the cooking heating device (IH heater). Further, an air passage through which cooling air flows is provided between the heating chamber 112 in which the water tank 430 in the casing 101 is disposed and the control circuit (280, 210). A cooling fan 236 is arranged on the rear side of the wind passage in the casing 101.

  According to the above configuration, the water tank storage portion 421 is disposed in the casing 101 so that the insertion port 421a of the water tank storage portion 421 opens forward from the lower side of the operation panel 280, and from the front side of the casing 101. Since the water tank 430 is inserted and attached to the insertion port 421a of the water tank storage part 421 below the operation panel 280, the horizontal width of the heating chamber 112 and the front operation panel 180 is not restricted by the water tank 430. The tank 430 can be easily mounted in the casing 101 from the front side.

  Therefore, in the IH cooking heater 100E which is a heating cooker provided with the cooking heating device (103A, 103B, 103C) and the heating chamber 112, the horizontal width of the heating chamber 112 and the front operation panel 180 is reduced without a simple configuration.

  Moreover, the water tank 430 can be attached and detached without interfering with the door 113 with a handle that opens and closes the opening of the heating chamber 112, and the operability is improved.

  In the fifth embodiment, the water tank storage part 421 is disposed below the operation panel 280. However, the present invention is not limited thereto, and the water tank storage part may be disposed above the operation panel.

  In the first to fifth embodiments, three IH heaters are used as cooking heaters. However, the present invention may be applied to a heating cooker using one or two IH heaters. You may apply this invention to the heating cooker which used not a heater but the electric stove, the gas stove, etc. as a heating apparatus for cooking.

  In the cooking device of the present invention, healthy cooking can be performed by using steam or superheated steam in a cooking heater (including an electric stove such as an IH heater or an electric heater or a gas stove). 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 attached to the food surface is condensed to give a large amount of condensation latent heat to the food. As a result, heat can be efficiently transferred to the food, and the food surface is baked crisply so that it can be cooked more than the finished product. 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. Furthermore, the inside of the heating chamber is filled with superheated steam or saturated steam and becomes oxygen-free, thereby enabling cooking while suppressing oxidation of food.

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