It is easy to use.

  In addition, since an estimate of the time required for heating cooking of the automatic cooking menu by the sensor is understood, it is convenient to calculate back when cooking is to be started by calculating backward from the time when the user wants to start eating.

  Hereinafter, an embodiment showing a heating cooking device of the present invention will be described with reference to the drawings.

  FIG. 1 is a block diagram showing an electrical configuration of an embodiment of the present invention. An AC power supply 1 from a commercial AC power supply or the like is supplied to a cooking device 12 of a microwave oven via a breaker 2. In the cooking device (microwave oven) 12, a microwave generation source 11 having a magnetron as a heating means is provided in the vicinity of the cooking chamber 3. As a result, the food placed in the cooking chamber 3 is cooked by dielectric heating using high-frequency microwaves from a magnetron.

  The humidity sensor 8 detects water vapor generated from the food when the food placed in the cooking chamber 3 is heated by the microwave generation source 11. Then, the signal of the humidity sensor 8 is input to the processing circuit 6 via the amplification circuit 5, and the processing circuit 6 (control means) obtains the heating state of the food.

  Further, a display means 9 is connected to the processing circuit 6, and information on the cooking time and the food cooking state calculated by the processing circuit 6 is displayed on the display means 9. The processing circuit 6 realized by a microcomputer or the like includes a read only memory (ROM) and a random access memory (RAM).

  The ROM stores a program for heating and cooking the food by the microwave generation source 11 based on the cooking time corresponding to the automatic cooking menu or the like selected by the input means 7, and further, the program is selected by the input means 7. When the time required for heating the automatic cooking menu by the sensor and the approximate heating time from the start of the heating of the automatic cooking menu by the sensor to the stop or the halfway stop are input to indicate the approximate required time, the approximate required time is displayed. A program to be displayed on the means is also stored.

  The switch circuit 10 switches whether to energize the microwave generation source 11 based on a signal provided from the processing circuit 6.

  FIG. 2 is a flowchart for explaining the display operation of the required cooking time in the present embodiment. After selecting a desired cooking menu (automatic sensor cooking, cooking with designated heating time, etc.) in advance, pressing the start key in step n1 and proceeding to step n2, the input means 7 determines whether the sensor automatic cooking menu has been selected. Is done. The sensor automatic cooking menu is selected by a sensor automatic cooking key provided on the input means 7.

  If the determination in step n2 is negative, the process ends, and the process proceeds to the heating time designation cooking or the like. On the other hand, if the determination in step n2 is affirmative, the process proceeds to step n3. At step n3, it is determined whether or not the display of the required heating time of the sensor automatic cooking menu is requested by a predetermined key input. If affirmative, the process proceeds to step n4.

  In step n4, the approximate heating time of the selected sensor automatic cooking menu is displayed on the display means 9 based on the value programmed in the ROM of the processing circuit 6 in advance. For example, if the selected cooking menu is "BAKED POTATO" and the heating time per piece is about 3 minutes, "3.00 / 1PC" or the like is displayed for a predetermined time.

  Further, the number and weight of BAKED POTATO can be detected by a position sensor or a weight sensor, and the required heating time can be displayed based on the detected values. For example, if there are three, it is possible to display such as "9.00 / 3PC".

  In step n5, the display of the time required from the start of heating of the predetermined sensor automatic cooking menu selected by the input means 7 to the halfway stop for "turning over the heated food", "adding new food", and the like is displayed. It is determined whether the request has been made, and if not, the process ends. If affirmative, the process proceeds to step n6.

  In step n6, based on the values preprogrammed in the ROM of the processing circuit 6, "turning over the food being heated" and "adding new food" from the start of heating of the sensor automatic cooking menu selected on the display means 9 are started. The estimated time required to stop halfway through "add" etc. is displayed. For example, if the menu selected is a meat dish and the required time from the start of heating per 0.1 kg to the halfway stop of “turning over food during heating” is about 5 minutes, “5.00 / 0.1KG” Is displayed.

  Here, the weight of the food can be obtained by the weight sensor, and the time required for the stoppage halfway can be changed and displayed based on the weight.

  In the present embodiment, at the start of heating of the sensor automatic cooking menu, the time until the end of heating and the time until the halfway stop are displayed.
