[0009] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings, the same or corresponding parts are designated by the same reference characters and description thereof will not be repeated.

[0010] A cooking system 1 according to this embodiment will be described with reference to Figures 1 and 2. Figure 1 is a diagram showing the cooking system 1 according to this embodiment. Figure 2 is a functional block diagram of the cooking system 1 according to this embodiment.

[0011] The cooking system 1 includes an oven 10 and a microwave oven 20. The microwave oven 20 is an example of a range. In this embodiment, the side of the oven 10 on which an opening / closing door 11D (described later) is located is defined as the front side of the oven 10 (cooking system 1), and the side opposite the front side (the rear side) is defined as the rear side of the oven 10 (cooking system 1). Furthermore, the right side of the oven 10 (cooking system 1) when viewed from the front side is defined as the right side of the oven 10 (cooking system 1), and the side opposite the right side is defined as the left side of the oven 10 (cooking system 1). Furthermore, in a direction perpendicular to the front-to-rear and left-to-right directions of the oven 10 (cooking system 1), the side on which a display unit 14 and an operating unit 15 (described later) are located is defined as the top side of the oven 10 (cooking system 1), and the side opposite the top side (the bottom side) is defined as the bottom side of the oven 10 (cooking system 1). These orientations do not limit the orientation of the oven 10 (cooking system 1) of the present invention during use.

[0012] In this embodiment, oven 10 and microwave oven 20 are arranged next to each other in a vertical direction. Specifically, oven 10 is arranged above microwave oven 20. Oven 10 and microwave oven 20 are examples of cooking appliances.

[0013] [Oven 10] Oven 10 includes cooking chamber 11, openable / closable door 11D, heating section 12, control section 13, display section 14, operation section 15, and housing 16.

[0014] As shown in FIG. 1, housing 16 has, for example, a substantially rectangular parallelepiped shape with an open front. Cooking chamber 11 is provided inside housing 16. Cooking chamber 11 accommodates an object to be cooked (not shown). Cooking chamber 11 is an example of a first cooking chamber. Typically, housing 16 is formed of a metal chassis. For example, cooking chamber 11 and housing 16 are formed integrally. Cooking chamber 11 is formed inside housing 16 and is covered with a heat-resistant insulator. Cooking chamber 11 is an example of a first cooking chamber.

[0015] The door 11D is a vertical-opening door. Specifically, the lower front edge of the housing 16 is set as a horizontal axis, and the door 11D is attached to the housing 16 so as to be rotatable around this horizontal axis. However, the door 11D of this embodiment is not limited to a vertical-opening door. For example, the door 11D may be a horizontal-opening door that is rotatable around the vertical axis, with the left side edge of the housing 16 set as a vertical axis.

[0016] The heating unit 12 heats the food item placed in the cooking chamber 11. As an example, the heating unit 12 includes a grill heater (not shown) and a blower fan (not shown). Typically, the grill heaters are located above and below the cooking chamber 11. Specifically, the grill heaters are attached to the ceiling and bottom (floor) of the cooking chamber 11, respectively. The blower fan is located on the rear wall of the cooking chamber 11. The grill heater and the blower fan perform convection cooking on the food item. The grill heater bakes or grills the food item. Baking is a cooking method in which the food item is indirectly cooked by heating the air in the cooking chamber 11. Grilling is a cooking method in which the food item is directly cooked by the heat of the grill heater.

[0017] The display unit 14 is disposed on the front side of the housing 16, above the opening and closing door 11D. The display unit 14 is a liquid crystal display, an organic EL display, or the like, that has the function of displaying a screen related to the preparation of the cooking target. The operation unit 15 accepts user operations. The display unit 14 and the operation unit 15 are typically formed integrally as a touch panel display. For example, the operation unit 15 is a touch sensor provided on the touch panel display. The touch sensor is, for example, a capacitance-type touch sensor. The touch sensor accepts touch operations, slide operations, or the like by the user. When the touch sensor detects a touch operation or slide operation, it outputs a signal indicating the detection result to the control unit 13. Note that the operation unit 15 may be a touch sensor provided on the touch panel display, or may be a physical button or a pressure-sensitive touch panel switch provided separately from the display unit 14.

[0018] The control unit 13 controls the heating unit 12, the display unit 14, and the operation unit 15. Specifically, the control unit 13 includes a processor such as a CPU (Central Processing Unit) or an MCU (Micro Controller Unit). The control unit 13 is mounted on a control board 13B. The control board 13B is a multilayer board in which multiple conductive layers and multiple insulating layers are alternately stacked.

[0019] In addition to the control unit 13, a power supply circuit or various circuit elements (not shown) are arranged on the control board 13B. For example, a memory unit 13M is arranged on the control board 13B. The memory unit 13M stores various programs, data, and the like. Specifically, the memory unit 13M includes semiconductor memory such as a read-only memory (ROM) and a random access memory (RAM), a solid-state drive (SSD), or a hard disk drive (HDD). The control unit 13 controls the heating unit 12 and the display of the display unit 14 by reading and executing various programs from the memory unit 13M. Note that the memory unit 13M may be provided on the control board 13B separately from the control unit 13, or may be provided in the control unit 13. Specifically, the memory unit 13M may be formed as a memory area included in the control unit 13.

[0020] [Microwave 20] The microwave oven 20 includes a cooking chamber 21, a heating unit 22, a control unit 23, a drawer body 24, and a housing 26.

[0021] Housing 26 has, for example, a substantially rectangular parallelepiped shape with an open front. Cooking chamber 21 is provided inside housing 26. Cooking chamber 21 has a predetermined volume as a space capable of accommodating an object to be cooked (not shown). Cooking chamber 21 is an example of a second cooking chamber. Typically, housing 26 is formed of a metal chassis. Cooking chamber 21 is an example of a second cooking chamber.

[0022] The drawer body 24 can be drawn out in the front-to-rear direction relative to the cooking chamber 21. The drawer body 24 is an example of a drawer section. In this embodiment, the drawer body 24 includes a drive mechanism 25, such as a motor, that drives the drawer body 24. The drive mechanism 25 is housed, for example, in the space between the bottom wall of the housing 26 and the bottom wall of the cooking chamber 21. The drive mechanism switches between a drawn-out state in which the drawer body 24 is drawn out from the cooking chamber 21 and a retracted state in which the drawer body 24 is retracted into the cooking chamber 21 under the control of the control unit 23 (described later). A door is provided in front of the drawer body 24 that can open and close the front opening of the cooking chamber 21. In the drawn-out state, the door opens the front opening of the cooking chamber 21, and in the retracted state, the door closes the front opening of the cooking chamber 21.

[0023] Heating unit 22 has a magnetron. The magnetron supplies microwaves to cooking chamber 21 to heat an object to be cooked placed in cooking chamber 21.

[0024] The control unit 23 controls the heating unit 22 and the drawer 24. Specifically, the control unit 23 includes a processor such as a CPU (Central Processing Unit) or an MCU (Micro Controller Unit). The control unit 23 is mounted on a control board 23B. The control board 23B is a multilayer board in which multiple conductive layers and multiple insulating layers are alternately stacked.

[0025] In addition to the control unit 23, a power supply circuit or various circuit elements (not shown) are arranged on the control board 23B. For example, a memory unit 23M is arranged on the control board 23B. The memory unit 23M stores various programs, data, and the like. Specifically, the memory unit 23M includes semiconductor memory such as a read-only memory (ROM) and a random access memory (RAM), a solid-state drive (SSD), or a hard disk drive (HDD). The control unit 23 reads and executes various programs from the memory unit 23M to control the heating unit 22 and the drive mechanism that drives the drawer body 24. The memory unit 23M may be provided on the control board 23B separately from the control unit 23, or may be provided in the control unit 23. Specifically, the memory unit 23M may be formed as a memory area included in the control unit 23.

[0026] In cooking system 1, control unit 13 of oven 10 and control unit 23 of microwave oven 20 can communicate with each other. For example, control unit 13 and control unit 23 are electrically and mechanically connected to each other via a communication harness. As a result, control unit 13 can control control unit 23, and can control heating unit 22 and drawer body 24 via control unit 23. Control unit 23 can also control control unit 13, and can control heating unit 12, display unit 14, and operation unit 15 via control unit 13. In other words, microwave oven 20 communicates with oven 10 via a wired connection. Note that oven 10 and microwave oven 20 may communicate with each other via a wired connection via a communication harness, or may communicate with each other via wireless communication, for example.

[0027] In cooking system 1, housing 16 of oven 10 and housing 26 of microwave oven 20 are mechanically connected to each other by a connecting member P1 made of a conductive metal. Specifically, connecting member P1 is attached to the lower right side of housing 16 and the upper right side of housing 26, as well as to the lower left side of housing 16 and the upper left side of housing 26 (not shown in FIG. 1).

[0028] The cooking system 1 can operate in a normal mode in which all functions related to the heating process of the cooking object by the heating unit 12 and the heating unit 22 are available, or in a limited mode (Sabbath MODE) in which some functions of the heating process of the cooking object by the heating unit 12 and the heating unit 22 are limited. In the cooking system 1, the normal mode and the limited mode (Sabbath MODE) can be switched between each other.

[0029] The restricted mode (Sabbath MODE) restricts functions related to heating that correspond to activities restricted during the Jewish Sabbath. For example, strict Orthodox Jewish law prohibits work, which also prohibits the use of fire and electrical appliances. While keeping cooked food warm using a lit stove or a preheated oven is sometimes permitted, not being able to use electrical appliances can be extremely inconvenient. Therefore, the restricted mode (Sabbath MODE) allows secular Jews to use only some functions, although not all functions, thereby improving convenience during the Jewish Sabbath. Therefore, the restricted mode (Sabbath MODE) of the present invention does not address all activities restricted during the Jewish Sabbath. For example, it does not completely restrict the on / off of the heating unit, lighting device (interior light), display unit (backlight), etc.

[0030] Next, operation of the cooking system 1 in the restricted mode will be described with reference to Figs. 3 to 9. Fig. 3 shows a main menu screen V1 displayed on the display unit 14 of the cooking system 1. Fig. 4 shows an example of a switching screen V2 displayed on the display unit 14 of the cooking system 1. Fig. 5 shows another example of the switching screen V2 displayed on the display unit 14 of the cooking system 1. Fig. 6 shows a temperature setting screen V3 displayed on the display unit 14 of the cooking system 1. Fig. 7 shows a heating period setting screen V4 displayed on the display unit 14 of the cooking system 1. Fig. 8 shows a preheating screen V5 displayed on the display unit 14 of the cooking system 1. Fig. 9 shows a heating screen V6 displayed on the display unit 14 of the cooking system 1.

[0031] In the cooking system 1, for example, when an operation is input to the operation unit 15 or the opening / closing door 11D is opened, the control unit 13 controls the display unit 14 to display the main menu screen V1.

[0032] 3 includes a first area R1 and a second area R2. In the first area R1, a plurality of icons S corresponding to various functions of the cooking system 1 are arranged. The plurality of icons S includes, as an example, an icon S1 corresponding to a setting function for setting various setting items of the cooking system 1.

[0033] In the second area R2, content corresponding to an icon S selected by the user from among the multiple icons S arranged in the first area R1 is displayed. Hereinafter, in this embodiment, a state in which the user performs a touch operation or a slide operation on an icon S displayed on the display unit 14 will be described as "selected."

[0034] 3, when icon S1 is selected, icons corresponding to multiple setting items are arranged in second area R2. The multiple icons arranged in second area R2 include icon S2 indicating restricted mode (Sabbath MODE).

[0035] When the user selects the icon S2, the control unit 13 controls the display unit 14 to display the switching screen V2. The switching screen V2 is a screen that guides the user to switch between normal mode and restricted mode. The display content of the second area R2 of the switching screen V2 is different from that of the main menu screen V1. In other words, the control unit 13 changes the display content of the second area R2 of the main menu screen V1 and causes the display unit 14 to display the switching screen V2.

[0036] The second area R2 of the switching screen V2 includes a message window W1 containing an explanation of the restricted mode (Sabbath MODE). The message window W1 includes a switch icon S3 that indicates whether the restricted mode (Sabbath MODE) is selected (ON) or not selected (OFF). The switch icon S3 switches between a first display (FIG. 4) and a second display (FIG. 5) depending on whether the restricted mode (Sabbath MODE) is selected (ON) or not selected (OFF).

[0037] 4 shows the switching screen V2 when the restricted mode (Sabbath MODE) is not selected (OFF). At this time, the control unit 13 controls the cooking system 1 in the normal mode. That is, the switch icon S3 in the first display indicates that the cooking system 1 is in the normal mode.

[0038] In this embodiment, the switch icon S3 is a toggle switch. The first display of the switch icon S3 indicates, for example, a state in which the switch is located at the left end of a slide bar and the slide bar is displayed in the same color as the background color of the second region R2. The switch icon S3 is an example of a switching image.

[0039] Furthermore, an icon S4 is arranged in the second area R2 of the switching screen V2. For example, the icon S4 is located below the message window W1 in the second area R2. The icon S4 indicates a transition to the temperature setting screen V3 or the heating period setting screen V4. The temperature setting screen V3 and the heating period setting screen V4 are screens that are displayed on the display unit 14 in the restricted mode (Sabbath MODE), and are examples of screens that are displayed when a heating process is performed by the heating unit 12 with some of its functions restricted.

[0040] In the normal mode (FIG. 4), icon S4 is controlled so that touch operations or slide operations on icon S4 are disabled. At this time, for example, control unit 13 controls display unit 14 to gray out icon S4. In FIG. 4, the grayed-out icon S4 is indicated by a dashed line.

[0041] In this state, when the user selects the switch icon S3, in other words, when the operation unit 15 accepts an operation to switch to restrict some functions, the control unit 13 switches the cooking system 1 from normal mode to restricted mode (Sabbath MODE) and controls the display unit 14 to switch the switch icon S3 on the switching screen V2 to the second display (FIG. 5). The second display of the switch icon S3 indicates, for example, a state in which the switch is located at the right end of the slide bar and the slide bar is displayed in a color different from the background color of the second region R2. In FIG. 5, the color of the slide bar that is different from the background color of the second region R2 is indicated by hatching.

[0042] In this way, in the cooking system 1, by displaying the switch icon S3, it is possible to notify the user that switching between the normal mode and the restricted mode (Sabbath MODE) is possible based on the user's operation. Therefore, the user can switch between the normal mode and the restricted mode (Sabbath MODE) at will. This improves the convenience of the cooking system 1 for secular Jews. Furthermore, if switching between the normal mode and the restricted mode (Sabbath MODE) is possible by timer control, even if the clock or timer is inaccurate, the influence of the inaccuracy of the clock or timer can be reduced by switching between the normal mode and the restricted mode (Sabbath MODE) based on the user's operation.

[0043] At this time, the control unit 13 also controls the display unit 14 to enable the icon S4. Specifically, the control unit 13 controls the display unit 14 to cancel the grayed-out display of the icon S4 and display it normally (FIG. 5). The control unit 13 may control the display unit 14 not to display the icon S4 in the second area R2 in the normal mode, but to display the icon S4 in the second area R2 in the restricted mode (Sabbath MODE). In this embodiment, the icon S4 is an example of a transition image. This makes it possible to impress upon the user that the mode has been switched to the restricted mode (Sabbath MODE).

[0044] In addition, in FIGS. 4 and 5, the switch icon S3 is depicted as a toggle switch, but the type of the switch icon S3 is not particularly limited.

[0045] Furthermore, when the control unit 13 switches the cooking system 1 from normal mode to restricted mode (Sabbath MODE), the control unit 13 controls the display unit 14 to gray out or hide icons S corresponding to restricted functions among the multiple icons S arranged in the first area R1. For example, the control unit 13 controls the display unit 14 to gray out or hide an icon Sa displaying the home screen, an icon Sb corresponding to grill cooking, and an icon Sc corresponding to range (microwave) cooking. In the following figures, grayed-out icons S are indicated by dashed lines. At this time, the operation unit 15 rejects touch operations or slide operations on the grayed-out icons S. In other words, in restricted mode (Sabbath MODE), the operation unit 15 accepts only operations related to functions other than the limited functions. As an example, the limited functions in restricted mode (Sabbath MODE) include turning on the backlight of the display unit 14, controlling the air blower fan, and supplying microwaves.

[0046] In this way, according to the cooking system 1, in the restricted mode (Sabbath MODE), it is possible to prevent the erroneous activation of functions corresponding to activities that are restricted on the Jewish Sabbath.

[0047] In particular, you will no longer choose to cook in the microwave, which has little to do with keeping the fire lit.

[0048] When the normally displayed icon S4 is selected, the control unit 13 controls the display unit 14 to display the temperature setting screen V3. However, when the icon S4 is selected, the heating period setting screen V4 may also be displayed. Also, the user may be able to set in advance which of the temperature setting screen V3 and the heating period setting screen V4 will be displayed when the icon S4 is selected. The following describes, as a representative example, the case when the switching screen V2 is switched to the temperature setting screen V3. Typically, the temperature setting screen V3 and the heating period setting screen V4 are dedicated screens for the limited mode (Sabbath MODE), but they may also be used in common with the normal mode.

[0049] 6, the temperature setting screen V3 differs from the switching screen V2 in the display content of the second area R2. That is, the control unit 13 changes the display content of the second area R2 of the switching screen V2 and causes the display unit 14 to display the temperature setting screen V3.

[0050] The second area R2 of the temperature setting screen V3 displays information about bake cooking, which is an example of a function available in the restricted mode (Sabbath MODE). Specifically, the second area R2 of the temperature setting screen V3 includes a temperature setting window W2 that shows the temperature setting of the heating cooking chamber 11 during bake cooking. The temperature setting window W2 is an example of a heating temperature setting image that shows the temperature setting for heating by the heating unit 12 (grill heater).

[0051] For example, the temperature setting window W2 includes a temperature display showing the set temperature for baking and a slide bar for changing the set temperature. When the user selects the slide bar and stops it at a predetermined position, the temperature corresponding to the stop position is set as the set temperature.

[0052] Furthermore, in addition to the temperature setting window W2, the second area R2 of the temperature setting screen V3 includes an icon S51 indicating the start of bake cooking, an icon S6 indicating transition to the heating period setting screen V4, and an icon S71 for turning on or off an interior light (not shown) disposed in the cooking chamber 11. For example, the icons S51, S6, and S71 are arranged side by side below the temperature setting window W2. Note that the arrangement of the temperature setting window W2, the icon S51, the icon S6, and the icon S71 in the second area R2 of the temperature setting screen V3 is not limited to the arrangement shown in FIG. 5.

[0053] For example, when icon S6 on the temperature setting screen V3 is selected, control unit 13 controls display unit 14 to display heating period setting screen V4 (FIG. 7) instead of temperature setting screen V3. As shown in FIG. 7, the heating period setting screen V4 differs from the temperature setting screen V3 in the display content of second region R2. That is, control unit 13 changes the display content of second region R2 on temperature setting screen V3 and causes display unit 14 to display heating period setting screen V4.

[0054] The second area R2 of the heating period setting screen V4 includes a heating period setting window W31 that indicates the setting of the heating period by the heating unit 12 (grill heater) during bake cooking, and a temperature setting window W32 that corresponds to the temperature setting window W2 of the temperature setting screen V3. The temperature setting window W32 displays the same content as the temperature setting window W2 except that the temperature setting operation differs from the operation for the temperature setting window W2, so a description of the temperature setting window W32 will be omitted.

[0055] The heating period setting window W31 displays the heating period selectable in a drum roll display. For example, the heating period that can be set in the heating period setting window W31 may exceed 12 hours. The heating period setting window W31 is an example of a heating period setting image that indicates the period setting for heating by the heating unit 12.

[0056] Furthermore, in addition to the heating period setting window W31 and the temperature setting window W32, the second area R2 of the heating period setting screen V4 also includes an icon S52 corresponding to the function of icon S51 on the temperature setting screen V3 (start bake cooking) and an icon S72 corresponding to the function of icon S71 on the temperature setting screen V3 (turn the interior light on and off). For example, the icons S52 and S72 are arranged side by side below the heating period setting window W31 and the temperature setting window W32.

[0057] The temperature setting screen V3 and the heating period setting screen V4 may each include an icon (not shown) for returning to the screen that was previously displayed on the display unit 14.

[0058] When icon S51 on the temperature setting screen V3 or icon S52 on the heating period setting screen V4 is selected, control unit 13 controls heating unit 12 (grill heater) based on the set temperature and heating period set on at least one of temperature setting screen V3 and heating period setting screen V4. At this time, control unit 13 controls display unit 14 to display preheating screen V5 (FIG. 8) or heating screen V6 (FIG. 9). Typically, preheating screen V5 and heating screen V6 are dedicated screens for limited mode (Sabbath MODE), but they may also be used in normal mode.

[0059] For example, if only the set temperature is set on the temperature setting screen V3 and icon S51 is selected, control unit 13 controls display unit 14 to display preheating screen V5. As shown in FIG. 8, the display content of second region R2 on preheating screen V5 is different from that on temperature setting screen V3. That is, control unit 13 changes the display content of second region R2 on temperature setting screen V3 and causes display unit 14 to display preheating screen V5. Second region R2 on preheating screen V5 includes a temperature display window W4 that shows the set temperature for bake cooking and the current temperature in cooking chamber 11. In temperature display window W4, the set temperature and the current temperature in cooking chamber 11 are indicated by a progress bar.

[0060] On the other hand, when the set temperature and heating period are set and icon S52 is selected on the heating period setting screen V4, the control unit 13 controls the display unit 14 to display a heating screen V6. As shown in FIG. 9, the display content of the second region R2 of the heating screen V6 is different from that of the heating period setting screen V4. That is, the control unit 13 changes the display content of the second region R2 of the heating period setting screen V4 and causes the display unit 14 to display the heating screen V6. The second region R2 of the heating screen V6 includes a temperature-time display window W5 that shows the set temperature for bake cooking and the time remaining until the end of bake cooking. Note that when the set temperature and heating period are set and icon S52 is selected on the heating period setting screen V4, the control unit 13 may also control the display unit 14 to display a preheating screen V5 before displaying the heating screen V6.

[0061] As described above, the display unit 14 displays the temperature setting window W2 and at least one of the heating period setting window W31 and the temperature setting window W32. Therefore, the user can easily recognize the functions available in the limited mode (Sabbath MODE).

[0062] In this embodiment, the preheating screen V5 includes an icon S91 along with the temperature display window W4. The icon S91 provides guidance for releasing the restricted mode (Sabbath MODE). When the icon S91 is selected, the control unit 13 controls the display unit 14 to display the switching screen V2. When the switch icon S3 is selected on the switching screen V2, the control unit 13 ends the restricted mode (Sabbath MODE) and switches to normal mode. The icon S91 is an example of a restriction release image that provides guidance for releasing restrictions on some functions in the restricted mode (Sabbath MODE).

[0063] On the other hand, the heating screen V6 includes an icon S92 along with the temperature and time display window W5. The icon S92, like the icon S91, provides a guide to cancel the restricted mode (Sabbath mode).

[0064] By providing icons S91 and S92 on the preheating screen V5 and the heating screen V6, respectively, which indicate instructions for canceling the restricted mode (Sabbath MODE), it is possible to switch to the switching screen V2 even during the heating process by the heating unit 12 in the restricted mode (Sabbath MODE), and to exit the restricted mode (Sabbath MODE) midway.

[0065] Note that the icon S91 on the preheating screen V5 and the icon S92 on the heating screen V6 may indicate an instruction to cancel the restricted mode (Sabbath MODE). In this case, when the icon S91 or the icon S92 is selected, the control unit 13 ends the restricted mode (Sabbath MODE) of the cooking system 1 and switches it to the normal mode. For example, when the control unit 13 cancels the restricted mode (Sabbath MODE), it controls the display unit 14 to display the main menu screen V1.

[0066] In this embodiment, when a predetermined period of time has elapsed while the temperature setting screen V3, the heating period setting screen V4, the preheating screen V5, or the heating screen V6 is displayed on the display unit 14, the control unit 13 controls the display unit 14 to turn off the backlight and put the display unit 14 in a non-display state. Next, when an operation is input to the operation unit 15 or the opening / closing door 11D is opened, the control unit 13 controls the display unit 14 to display the screen that was displayed on the display unit 14 before the backlight was turned off, from among the temperature setting screen V3, the heating period setting screen V4, the preheating screen V5, and the heating screen V6.

[0067] Next, the operation when the mode is changed to the restricted mode (Sabbath mode) will be described with reference to Fig. 10. Fig. 10 is a diagram showing the cooking system 1 when the drawer body 24 is in the drawn state.

[0068] When the cooking system 1 switches from the normal mode to the limited mode (Sabbath MODE), if the drawer body 24 is in the drawn state, the control unit 13 controls the drawer body 24 to be pushed into the cooking chamber 21.

[0069] For example, an open / close sensor that detects whether the drawer body 24 is pushed in or pulled out is provided in the drawer body 24 or the cooking chamber 21. When the cooking system 1 is switched from the normal mode to the restricted mode (Sabbath mode), the control unit 13 determines whether the drawer body 24 is pushed in or pulled out based on the detection result of the open / close sensor.

[0070] When the control unit 13 determines that the drawer body 24 is in the drawn state, it switches the switch icon S3 on the switching screen V2 to the second display (FIG. 5) and controls the drive mechanism 25 to store the drawer body 24 in the cooking chamber 21.

[0071] The cooking system 1 also includes an interior light 27 that illuminates the cooking chamber 21. The interior light 27 is an example of a lighting device. The control unit 13 controls the interior light 27 to turn on when the drawer body 24 is in the drawn-out position, and to turn off when the drawer body 24 is in the retracted position. Therefore, when the cooking system 1 switches from the normal mode to the restricted mode (Sabbath mode), if the interior light 27 is on, the control unit 13 controls the interior light 27 to turn off.

[0072] In detail, when the cooking system 1 switches from the normal mode to the restricted mode (Sabbath MODE), if the control unit 13 determines that the drawer body 24 is in the drawn state, it controls the drive mechanism 25 so that the drawer body 24 is stored in the cooking chamber 21, and also controls the interior light 27 so that the interior light 27 is turned off.

[0073] As described above, by making the cooking system 1 closer to a typical standby state when switching from normal mode to restricted mode (Sabbath MODE), it becomes less likely that a user will operate the cooking system 1 on the Sabbath in restricted mode (Sabbath MODE).

[0074] Next, a mode switching method in the cooking system 1 according to this embodiment will be described with reference to Fig. 11. Fig. 11 is a flowchart showing the mode switching method in the cooking system 1 according to this embodiment.

[0075] The control unit 13 controls the display unit 14 to display the main menu screen V1 (step S11).

[0076] The control unit 13 controls the display unit 14 to continue displaying the main menu screen V1 until an icon S2 indicating the restricted mode (Sabbath MODE) is selected on the main menu screen V1 (No in step S12). On the other hand, when the icon S2 is selected (Yes in step S12), the control unit 13 controls the display unit 14 to display the switching screen V2 (step S13).

[0077] On the switching screen V2, each time the switch icon S3 is selected, the selection state (ON) or non-selection state (OFF) of the restricted mode (Sabbath MODE) is switched (Step S14). When the selection state (ON) of the restricted mode (Sabbath MODE) is selected (Yes in Step S14), the control unit 13 switches the cooking system 1 to the restricted mode (Sabbath MODE) and controls the display unit 14 to switch and display the switch icon S3 on the switching screen V2 to the second display (Step S15).

[0078] Furthermore, the control unit 13 controls the display unit 14 to cancel the grayed-out display of the icon S4 (transition image) and display it normally, thereby enabling the icon S4 (transition image) (step S16).

[0079] When the valid icon S4 is selected, the control unit 13 controls the display unit 14 to display a dedicated screen for the restricted mode (Sabbath MODE) (step S17).

[0080] The control unit 13 controls the display unit 14 to continue displaying the dedicated screen until the icon S91 or icon S92 (restriction release image) included in the dedicated screen is selected (No in step S18). On the other hand, when the icon S91 or icon S92 is selected (Yes in step S18), the control unit 13 controls the display unit 14 to display the switching screen V2 (step S13).

[0081] On the other hand, when the non-selected state (OFF) of the restricted mode (Sabbath MODE) is selected on the switching screen V2 (No in step S14), the control unit 13 switches the cooking system 1 to the normal mode (step S19) and controls the display unit 14 to switch the switch icon S3 on the switching screen V2 to the first display (step S20). The control unit 13 controls the display unit 14 to display the main menu screen V1 (step S11).

[0082] The embodiments of the present invention have been described above with reference to the drawings. However, the present invention is not limited to the above embodiments and can be implemented in various forms without departing from the spirit of the present invention. Furthermore, the components disclosed in the above embodiments can be modified as appropriate. For example, some of the components shown in one embodiment may be added to the components of another embodiment, or some of the components shown in one embodiment may be deleted from the embodiment.

[0083] In this embodiment, the cooking system 1 includes the oven 10 and the microwave oven 20, but the cooking system 1 may include only one of the oven 10 and the microwave oven 20. The cooking system 1 may also include an oven range in which the oven and the microwave oven are integrated.

[0084] In this embodiment, if the cooking system 1 is powered off in the restricted mode (Sabbath MODE), when the cooking system 1 is powered on again, the control unit 13 starts the cooking system 1 in the restricted mode (Sabbath MODE). For example, if the cooking system 1 is powered off while the temperature setting screen V3, the heating period setting screen V4, the preheating screen V5, or the heating screen V6 is displayed on the display unit 14, when the cooking system 1 is powered on again, the control unit 13 controls the display unit 14 to display one of the temperature setting screen V3, the heating period setting screen V4, the preheating screen V5, or the heating screen V6 that was displayed on the display unit 14 before the power was turned off.

[0085] Furthermore, the drawings mainly show each component in a schematic manner to facilitate understanding of the invention, and the thickness, length, number, spacing, etc. of each component shown in the drawings may differ from the actual ones due to the convenience of creating the drawings.
