  The room temperature sensor 74 is for detecting the room temperature, and the steam temperature sensor 75 is for detecting the temperature in the steam generator 28, and is composed of, for example, a thermistor. The limit switch 54 is for detecting the insertion / removal state of the water storage container 48 described above.

  The magnetron drive circuit 76, the heater drive circuit 77, the steam supply device heater drive circuit 78, and the feed pump drive circuit 79 are circuits for driving the magnetron 17, the heater 12 in the hot air oven unit 11, and the feed pump 27, respectively. is there.

  In addition to this, the heating cooker 1 is provided with a motor 22 for a rotating antenna, a fan motor 14 for a hot air oven unit 11, a motor for a cooling fan of a cooling fan device 15, a door switch, a planar heater 10, and the like. Since these are not directly related to the operation of the present invention which is controlled by the control circuit 71, they are omitted in FIG.

  As described above, all the dew condensation water generated by condensation of the heated steam supplied from the steam supply device 25 is collected in the water storage container 48 of the water reservoir 47. If the water accumulated in the water reservoir 47 is left as it is, the water will eventually overflow and the floor surface will be soiled. Therefore, in the heating cooker 1 of the present embodiment, it is determined that water has accumulated in the water reservoir 47, and a warning (notification) that prompts the user to discard the water is performed.

  This warning for discarding water is given by one of the following methods. The first method is a method that always gives a warning at the end of cooking when the steam supply device 25 is operated. When a cooking menu for cooking while using heated steam is executed, the steam supply device 25 is also automatically started to operate. In addition to the automatic operation based on the selection of the cooking menu, the steam supply device 25 may be operated manually.

  Since the steam supply device 25 operates according to an instruction from the control circuit 71, the control circuit 71 knows whether or not the steam supply device 25 has operated. When the steam supply device 25 is operated, it is estimated that water has accumulated in the water reservoir 47, so that a warning is given at the end of cooking. The warning is performed by blinking the “water catcher” character 91 in the display portion 8a of FIG.

  The second method is a method in which the time during which the steam supply device 25 is operated is integrated and a warning is given at the end of cooking after the integrated value reaches a predetermined value. Even if the steam supply device 25 is operated, the amount of water that must be thrown away is not always collected by one-time cooking. Therefore, the amount of water accumulated in the water reservoir 47 is estimated from the operation time of the steam supply device 25, and a warning is given when it is determined that the predetermined amount has been reached. The operation of the steam supply device 25 is performed according to an instruction from the control circuit 71. Accordingly, a timer is provided in the control circuit 71 to accumulate the operation time, and a warning is given at the end of cooking after the value reaches a predetermined value.

  The third method is a method in which the amount of heated steam supplied to the heating chamber 4 is estimated and a warning is given at the end of cooking after the value reaches a predetermined value. The supply amount of the heating steam is proportional to the amount of water supplied from the feed water pump 27 to the steam generator 28, and the amount of water is proportional to the operation time of the feed water pump 27. The feed water pump 27 is operated intermittently at a constant rotational speed. Therefore, if the time during which the feed water pump 27 is operated is integrated, the amount of heating steam supplied to the heating chamber 4 can be determined. The water supply pump 27 is also operated by an instruction from the control circuit 71. Accordingly, a timer is provided in the control circuit 71 to accumulate the operation time, and a warning is given at the end of cooking after the value reaches a predetermined value.

  By such a method, it is possible to determine when to give a warning prompting to throw away water. In the second and third methods, the warning timing is determined when the integrated value reaches a predetermined value. However, the amount of dew condensation water varies with room temperature. When the room temperature is low, the amount of condensed water tends to increase. For this reason, even if the integration time is the same, the amount of water stored in the water reservoir 47 varies depending on the room temperature. Accordingly, if the predetermined value is corrected to a small value when the room temperature detected by the room temperature sensor 74 is low and is determined to be a large value when the room temperature is high, the accuracy of the timing for issuing a warning can be improved. .

  Note that the warning prompting the user to discard the water may be made by blinking the “water catcher” character 91 in the display portion 8a of FIG. You may use together. In addition, artificial voice by the voice output device 83 may be used together.

  Further, after the warning, if the water reservoir 47 is not removed even after a predetermined time has passed, it is preferable to issue a warning again with a buzzer sound or artificial voice. Whether or not the water reservoir 47 has been removed can be detected by the limit switch 54. Further, the warning is stopped when it is determined by the detection signal from the limit switch 54 that the water reservoir 47 has been removed.

Further, in the second and third methods, even after issuing a warning, the integration may be continued until it is detected that the water reservoir 47 has been removed.
As described above, in the heating cooker 1 of the present embodiment, all the condensed water formed by condensation of the heated steam is collected in the water reservoir 47 that can be inserted and removed. Then, the control circuit 71 determines the amount of water accumulated in the water reservoir 47 and issues a warning for urging the user to discard the water. Therefore, there is an effect of preventing the condensed water from spilling on the floor surface when the user discards the water according to the warning.
