  The configuration of the menu selection dial 84 and the menu determination button 85 is not limited to the above configuration. The menu selection dial 84 and the menu determination button 85 may be separately disposed and may be configured by a single dial that can be rotated and pressed.

  Hereinafter, the steam heating operation of the heating cooker 1 having the above configuration will be described with reference to FIGS.

  A screen as shown in FIG. 6 or 7 is displayed on the display unit 81 of the operation panel 11. Here, in the display example shown in FIG. 6, based on the ON signal from each of the micro switches 91 to 93, the control device 80 does not place the square tray 58 on all the locking portions 74 to 79. This is the display when judged. In this case, the character string “no corner tray” is displayed in the tray display area 82 of the display unit 81 of the operation panel 11. Furthermore, all the cooking menus are displayed in the menu display area 83, and the microwave cooking menu can be selected from the steam cooking menu. On the other hand, in the display example shown in FIG. 7, the control device 80 determines that the square tray 58 is placed on any one of the locking portions 74 to 79 based on the ON signals from the micro switches 91 to 93. It is a display of the case. In this case, the character string “with corner tray” is displayed in the tray display area 82. Further, in the menu display area 83, the name of the microwave oven menu is displayed at a lighter concentration than the name of the steam cooking menu. Further, even if the user operates the menu selection dial 84 to select the microwave oven menu and operates the menu determination button 85 to determine the microwave oven menu, the control device 80 accepts the selection of the microwave oven menu. There is no.

  This menu display restriction is performed at least when the menu is selected before cooking, and if the cooking operation is being performed, the menu display area 83 displays the operation content of the menu currently being cooked (the remaining time of cooking time). And the temperature in the heating chamber 20) are displayed.

  When the operation panel 11 is operated by the user on the display screen of the operation panel 11 as shown in FIG. 6 or 7 and the start key (not shown) is pressed after the steam cooking menu is determined, steam heating is performed. Cooking operation is started. Then, first, the control device 80 starts the operation of the pump 35. Then, water is supplied from the water tank 30 into the steam generator 40 via the water supply pipe 33 by the pump 35. Thereafter, when the water level in the steam generator 40 reaches a predetermined water level, the pump 35 is stopped to stop water supply.

  After that, the blower fan 28 and the damper 68 are controlled to perform the exhaust operation in the heating chamber 20. Thus, before starting the cooking, the steam in the heating chamber 20 is exhausted, so that the temperature or humidity in the heating chamber 20 is lower than the initial temperature or lower than the initial humidity determined by the cooking program. is there.

  Next, the steam generating heater 42 is energized, and a predetermined amount of water accumulated in the steam generating apparatus 40 is heated by the steam generating heater 42. Thus, when the water in the steam generator 40 boils, saturated steam is generated. When the steam generating heater 42 is energized or when the temperature of the water in the steam generating apparatus 40 reaches a predetermined temperature, the blower fan 28 is turned on and the steam heater 52 in the steam heating chamber 50 is energized. Then, the blower fan 28 sucks the gas (including steam) in the heating chamber 20 from the suction port 25 and sucks saturated steam generated in the steam generation device 40 from the steam supply port 62 to enter the external circulation path 60. It sends out gas (including steam). Thus, the steam from the heating chamber 20 and the steam from the steam generator 40 sent out by the blower fan 28 flow into the steam heating chamber 50 through the external circulation path 60 at a high speed.

  The steam that has flowed into the steam heating chamber 50 is heated by the steam heater 52 and becomes superheated steam at approximately 300 ° C. (depending on the cooking content). A part of this superheated steam is ejected downward from the plurality of ceiling steam outlets 55 provided in the lower ceiling panel 54 in the heating chamber 20. Further, another part of the superheated steam is ejected from the side surface steam outlets 22 on both side surfaces of the heating chamber 20 through the steam supply passages 23 provided on the left and right sides of the steam heating chamber 50.

  Thus, the superheated steam ejected from the ceiling side of the heating chamber 20 is vigorously supplied toward the heated object side in the center, and the superheated steam ejected from the left and right side surfaces of the heating chamber 20 collides with the receiving tray 21. Then, it is supplied while being lifted so as to wrap the object to be heated from below the object to be heated. As a result, in the heating chamber 20, convection occurs in such a manner that it blows down at the center and rises outside thereof.

  Thus, by forming the convection of the superheated steam in the heating chamber 20, the superheated steam from the steam heating chamber 50 is sent to the ceiling steam outlet 55 while maintaining the temperature / humidity distribution in the heating chamber 20 uniform. And the side surface steam outlet 22 to efficiently collide with the object to be heated placed on the corner tray 58, and the object to be heated is heated by the collision of the superheated steam. .

  Further, when time elapses during the cooking operation, the amount of steam in the heating chamber 20 increases, and the surplus amount of steam is discharged from the discharge port 27 to the discharge passage 64 and the first exhaust duct. The air is exhausted from the first exhaust port 66 through 65. The water condensed in the discharge passage 64 flows down in the discharge passage 64 and is guided to the receiving tray 21, and is processed together with the water generated by cooking after the cooking.

  Thus, when a predetermined time before the end of cooking (“1 minute before” in the present embodiment) is reached, the damper 68 of the external circulation path 60 is opened. Then, the external circulation path 60 communicates with the second exhaust duct 69, and the steam in the heating chamber 20 is blown by the blower fan 28 via the suction port 25, the external circulation path 60, the exhaust path 67 and the second exhaust duct 69. And is discharged from the second exhaust port 70. By doing so, the steam in the heating chamber 20 at the end of cooking is reduced, and the time until the start of the next cooking can be shortened.

  Further, the above-described damper operation functions in the same manner when the user opens the door 12 during cooking. That is, when the user opens the door 12, the control device 80 detects that the door 12 has been opened by a sensor (not shown), and instantly opens the damper 68 of the external circulation path 60. Therefore, it is possible to prevent the user from being exposed to steam.

  After cooking, the control device 80 displays a cooking end message on the operation panel 11, and a buzzer (not shown) provided on the operation panel 11 sounds a signal.

  Even when a user who knows the end of cooking by these messages and buzzer opens the door 12, the damper 68 and the blower fan 28 may be controlled to perform the exhaust operation. In that case, the user can take out the object to be heated from the heating chamber 20 more safely without being exposed to steam.

  The above description is for the steam heating operation.

  On the other hand, in the case of the microwave heating operation, the start key is displayed after the user operates the operation panel 11 and the microwave cooking menu is determined on the display screen of the operation panel 11 as shown in FIG. When (not shown) is pressed, the microwave heating cooking operation is started. Then, the controller 80 drives the magnetron 71 to supply microwaves to the object to be heated via the waveguide 72 and the rotating antenna 73 to heat the object to be heated. In this case, a non-metal receiving tray that transmits the microwave on which the object to be heated is placed is laid on, for example, the bottom plate of the heating chamber 20.

  As described above, in the above embodiment, in order to lay the square tray 58 made of stainless steel on the side walls 56 and 57 of the heating chamber 20, the locking portions 74 and 75 are arranged in the upper stage, and the locking parts 76 are arranged in the middle stage. 77, and locking portions 78, 79 are arranged in the lower stage. Further, the first micro switch 91 is installed in the upper locking portion 74, the second micro switch 92 is installed in the middle locking portion 76, and the third micro switch 93 is installed in the lower locking portion 78. It is installed.

  When the control device 80 determines that the square trays 58 are not placed on all the locking portions 74 to 79 based on the ON signals from the micro switches 91 to 93, As shown in FIG. 6, a character string “no corner tray” is displayed in the tray display area 82 of the display unit 81 of the operation panel 11, and all cooking menus are displayed in the menu display area 83, and steam is displayed. The cooking menu can be selected from the microwave menu.

  On the other hand, if the control device 80 determines that the square tray 58 is placed on any of the locking portions 74 to 79 based on the ON signals from the micro switches 91 to 93, the tray 80 In the display area 82, the character string “with corner tray” is displayed, and in the menu display area 83, the name of the microwave oven menu is displayed at a lighter concentration than the name of the steam cooking menu. And the control apparatus 80 does not accept selection of a microwave oven menu.

  Therefore, according to the above-described embodiment, in the cooking device using superheated steam and microwaves, it is possible to prevent forgetting to remove the metal corner tray 58 when performing cooking using the microwave oven menu. Heat cooking can be performed. That is, the corner tray 58 can be taken out of the heating chamber 20 without forgetting in the warming mode even in a household where the warming mode using microwaves is less frequently used.

  In the above embodiment, when the control device 80 determines that the square tray 58 is placed on any of the locking portions 74 to 79, as shown in FIG.
