    • PURPOSE:To improve the uniform heating function by providing suction holes at the center of the upper surface of a heating chamber having square-shaped upper surface and blow-off holes at four corners, connecting the section hole to the blow-off holes by means of a cross air guide, and accommodating therein a heater and a fan. CONSTITUTION:Foodstuff placing shelves 37 formed by a wire material are provided in a substantially square heating chamber 21 having a horizontal section, and suction holes 38 are formed at the substantially central part of the heating chamber 21 and blow-off holes are formed at four corners thereof. These suction holes and blow-off holes are connected to each other by an air guide 22, and the fan 23 and the heater 24 are accommodated in a space surrounded by the air guide 22 and the upper surface wall of the heat chamber 21. The fan 23 is positioned on the suction hole 38, and the center of the rotation of the fan is set at the substantially central part of the upper surface of the heating chamber 21. As a result, as the uniform heating function is maintained excellently, simultaneous cooking at two upper and lower stages, even a large cake having a size in such a degree as contacting the fan wall surfaces of the heating chamber, can be baked at least on its upper and lower surfaces.

    • PURPOSE:To improve the operation of the heating cooker which can perform heating by heater and heating by high frequency by a method wherein a cooking chamber cooling time is operated and displayed by a microcomputer based on an initial temperature of the cooking chamber being heated, a desired temperature of the cooking chamber and a heat time constant necessary for cooling the inside of the cooking chamber. CONSTITUTION:In the heating by high frequency after the heating by heater, a microcomputer 26 stores the cooking chamber temperature T1 at the completion of the heater heating inputted from a heat sensitive element 17 and also the desired cooking chamber temperature inputted from a keyboard 20. The microcomputer 26 operates the cooling time of the inside of the cooking chamber along a particular program on the base of said inputs from the element 17 and keyboard 20 as well as the heat time constant K necessary for cooling the chamber inside which is preliminarily stored therein and displays the result in a display tube 21. Then, maintaining the stop condition of signal outputs to various electric parts, discounting the cooling time, the microcomputer 26 informs, when the time is discounted up, of this effect. Such an arrangement makes the heating cooker to be easy to use.
