[0046] The smartphone 50 is equipped with a smartphone controller 60 that controls the overall operation of the smartphone 50. The smartphone controller 60 is an electronic circuit unit composed of a CPU, memory, various interface circuits, etc., and functions as a data acquisition unit 61 that controls the acquisition of cooking recipe data, a terminal-side storage unit 62 that stores the acquired cooking recipe data, a cooking recipe selection unit 63, a terminal-side display control unit 64 that controls the display of a display image displayed on the touch panel 51, and a terminal-side communication control unit 65 by executing a control program for the smartphone 50 stored in the memory by the CPU.

[0047] The smartphone 50 also includes a touch panel 51 that is touched by the user and displays various display images, a terminal speaker 52 that outputs sound and the like, and a terminal communication circuit 53 (terminal communication unit) that communicates with an external server and the gas stove 1. Thus, the touch panel 51 constitutes a terminal display unit and a terminal operation unit. As will be described later, the cooking recipe displayed on the touch panel 51 includes cooking conditions such as ingredients to be used, cooking utensils to be used, cooking steps, and cooking time.

[0048] The smartphone controller 60 receives touch operation signals from the touch panel 51 and signals received by the terminal-side communication circuit 53. In addition, a control signal transmitted from the smartphone controller 60 controls the display image on the touch panel 51, the audio output from the terminal-side speaker 52, and the transmission of signals by the terminal-side communication circuit 53.

[0049] 4 to 8, the user's operations and the display on touch panel 51 when operating stove operation panel 13 of gas stove 1 in the cooking system of this embodiment to give instructions to gas stove 1 related to a cooking recipe displayed on touch panel 51 of smartphone 50 and change a display image related to a cooking recipe displayed on touch panel 51 of smartphone 50 will be described using the noodle boiling process for cooking pasta as an example. Note that the user's operations when cooking based on a different cooking recipe in another heating unit are similar to these.

[0050] When a user operates the smartphone 50 to start a recipe selection app while wireless communication 81 is established between the gas stove 1 and the smartphone 50, the smartphone controller 60 starts processing, and a recipe search screen D1 shown in Fig. 4(a) is displayed on the touch panel 51. Then, when the user selects a desired cooking recipe, a recipe selection screen D2 shown in Fig. 4(b) is displayed on the touch panel 51.

[0051] The recipe selection screen D2 displays, for example, a recipe name 100, a recipe dish image 101, cooking utensils to be used 102, cooking time 103, recipe comments 104, and a display image of a "Send recipe" button 105 that instructs the gas stove 1 to send cooking condition data.

[0052] Since ingredients and cooking steps are not displayed on recipe selection screen D2 in FIG. 4(b), if the user wants to scroll recipe selection screen D2 upwards on stove operation panel 13 to view them instead of operating touch panel 51, the user presses "smartphone operation" switch 36 to switch from stove operation mode to smartphone operation mode. At this time, indicator lamp 37 provided on "smartphone operation" switch 36 etc. lights up. This allows the user to recognize which switches on stove operation panel 13 can be operated.

[0053] Next, instead of operating the touch panel 51, the user presses the "up" switch 32 once, and a control signal including instruction information for moving the display image on the touch panel 51 upward is transmitted from the gas stove 1 to the smartphone 50. The smartphone 50 then receives the instruction information and controls the touch panel 51 to scroll the recipe selection screen D2 upward a predetermined distance based on the instruction information. As a result, the display images of the ingredient list 106, cooking instructions 107, and video 108 shown in FIG. 5(a) are displayed on the touch panel 51. If the user wants to scroll the recipe selection screen D2 on the touch panel 51 downward, the user similarly presses the "down" switch 33 once.

[0054] Furthermore, when the user scrolls recipe selection screen D2 upward and the display image of video 108 is displayed below, instead of operating touch panel 51, the user presses "OK" switch 34 once, and a control signal including instruction information to play video 108 is transmitted from gas stove 1 to smartphone 50. Then, smartphone 50, which has received the instruction information, plays video 108 based on the instruction information. When the user wants to stop video 108, the user similarly presses "OK" switch 34 once again.

[0055] Also, when the user wants to enlarge the recipe selection screen D2 of FIG. 4(b) on the stove operation panel 13 instead of operating the touch panel 51, in the smartphone operation mode, the user presses the "up" switch 32 twice in succession in the same manner as described above, and a control signal including instruction information for enlarging the display image of the touch panel 51 is transmitted from the gas stove 1 to the smartphone 50. Then, the smartphone 50 that has received the instruction information controls the touch panel 51 to enlarge the recipe selection screen D2 based on the instruction information. As a result, the enlarged recipe selection screen D2 shown in FIG. 5(b) is displayed on the touch panel 51. At this time, the user can perform the above-mentioned scrolling as necessary. When the user wants to reduce the recipe selection screen D2 and return it to the standard size, the user similarly presses the "down" switch 33 twice in succession. Although not shown, when the display screen of the touch panel 51 is automatically forwarded, the next display screen is displayed on the touch panel 51 by pressing and holding the "OK" switch 34 of the stove operation panel 13. Therefore, when scrolling, enlarging and reducing, automatically forwarding, and playing and stopping videos on the display image of the smartphone 50 described above, the display image relating to the cooking recipe displayed on the touch panel 51 of the smartphone 50 is changed by operating the stove operation panel 13 of the gas stove 1 without the user having to operate the smartphone 50.

[0056] When the user checks a cooking recipe and instructs the gas stove 1 to transmit cooking condition data from the smartphone 50 to the gas stove 1 on the stove operation panel 13 instead of operating the touch panel 51, when the user presses the "OK" switch 34 once on the recipe selection screen D2 shown in Fig. 4(b), the gas stove 1 transmits a control signal including input of recipe transmission on the touch panel 51 and instruction information for changing the display image of the "Recipe Transmission" button 105 to the smartphone 50. Then, based on the instruction information, the smartphone 50 that has received the instruction information changes the display image of the "Recipe Transmission" button 105 shown in Fig. 6(a) to an image to which a pseudo instruction has been input (for example, a change in display color), and transmits cooking condition data corresponding to the selected cooking recipe from the smartphone 50 to the gas stove 1.

[0057] When the recipe transmission from the smartphone 50 to the gas stove 1 is normally completed, the smartphone 50 transitions the touch panel 51 from the recipe selection screen D2 to a stove selection screen D3 shown in Fig. 6(b). On the stove selection screen D3, display images of selection buttons 110, 111, 112 for the left, right, and rear stoves and an "OK" button 113 are displayed.

[0058] When the user selects the stove to be used on stove operation panel 13 instead of operating touch panel 51, in smartphone operation mode, each time the user presses "up" switch 32 once, a control signal including instruction information for moving the selected position of the stove is transmitted from gas stove 1 to smartphone 50. In response, smartphone 50, which has received the instruction information, changes the display image of one of the stove selection buttons to one displayed in a predetermined selection state (for example, by changing the display color) based on the instruction information (not shown).

[0059] When the user presses the "OK" switch 34 once while the display mode of the stove used by the user (for example, the left stove 10a) has been changed, a control signal including input of stove selection transmission on the touch panel 51 and instruction information for changing the display image of the "OK" button 113 is transmitted from the gas stove 1 to the smartphone 50. In response to the instruction information, the smartphone 50 changes the "OK" button 113 to a display image (not shown) to which a pseudo instruction has been input (for example, a change in display color) based on the instruction information, and transmits stove selection information from the smartphone 50 to the gas stove 1. As a result, automatic heating cooking corresponding to the selected cooking recipe is performed on the stove selected by the user.

[0060] When the transmission of the stove selection information from the smartphone 50 to the gas stove 1 is completed successfully, the smartphone 50 transitions the touch panel 51 from the stove selection screen D3 to the ignition waiting state screen D4 including an ignition instruction display image shown in FIG. 7(a).

[0061] When the user places cooking utensils containing water on the left burner 10a and then operates the left burner operation switch 11a to turn on the left burner 10a, a control signal including ignition status information is transmitted from the gas stove 1 to the smartphone 50. In response to the ignition status information, the smartphone 50 transitions the touch panel 51 from the ignition standby status screen D4 to a heating status screen D5 including a display image showing the heating status shown in FIG. 7(b) based on the ignition status information.

[0062] Next, when boiling is detected by the temperature sensor 15a of the left burner 10a, the heat of the left burner 10a is reduced, and a control signal including heating status information indicating the boiling state of the water based on the temperature detected by the temperature sensor 15a is sent from the gas stove 1 to the smartphone 50. Then, based on the heating status information, the smartphone 50 transitions the touch panel 51 from the heating screen D5 to a noodle-adding work screen D6 including a display image of a work instruction 122 for adding noodles and an "OK" button 123 shown in FIG.

[0063] When the user completes the noodle-adding task of adding noodles to the cooking utensil and instead of operating the touch panel 51, input is made to the "OK" button 123 on the stove operation panel 13. In the smartphone operation mode, when the user presses the "OK" switch 34 once, a control signal including an input of sending the completion of adding noodles on the touch panel 51 and instruction information for changing the display image of the "OK" button 123 is transmitted from the gas stove 1 to the smartphone 50. Then, the smartphone 50 that has received the instruction information changes the "OK" button 123 to a display image (not shown) to which a pseudo instruction has been input (for example, a change in display color) based on the instruction information, and transmits a control signal including information on the completion of adding noodles from the smartphone 50 to the gas stove 1. Therefore, in the above-mentioned cooking condition data transmission process, stove selection process, ignition process, and noodle-adding task process, the user operates the stove operation panel 13 of the gas stove 1 without operating the smartphone 50, and inputs an instruction to the gas stove 1 regarding the cooking recipe displayed on the touch panel 51 of the smartphone 50 and changes the display image regarding the cooking recipe displayed on the touch panel 51 of the smartphone 50.

[0064] The gas stove 1, which has received the information that the noodles have been added, controls the heat and continues to boil the noodles for the set predetermined time. At this time, the gas stove 1 controls the heat based on the cooking condition data, and executes a process to detect when the state inside the cooker into which the noodles have been added is a sign of an overflow (a state in which overflow is about to occur), and a process to detect when the sign of overflow has disappeared. When the predetermined time has passed, the gas stove 1 notifies the cooker speaker 46 that the noodles are done.

[0065] As described above in detail, according to the present embodiment, the user can operate the stove operation panel 13 without directly touching the smartphone 50, thereby executing instructions to the gas stove 1 regarding the cooking recipe displayed on the touch panel 51. Therefore, the smartphone 50 is not operated with wet or dirty hands, so that malfunctions and failures of the smartphone 50 can be prevented. In addition, the gas stove 1, which is generally installed in the kitchen and is assumed to come into contact with water, food ingredients, detergent, etc., is more water-resistant and stain-resistant than the smartphone 50, so that even if the stove operation panel 13 gets wet or dirty due to the user's operation, malfunctions and failures are unlikely to occur. In addition, the stove operation panel 13 can be cleaned more easily than the touch panel 51. Therefore, there is less need to wipe or wash your hands after each operation. This can improve usability.

[0066] Furthermore, according to this embodiment, before or during cooking, when the user's hands are often wet or dirty due to preparing ingredients, the user can operate the stove operation panel 13 to execute instructions to the gas stove 1 regarding the cooking recipe displayed on the touch panel 51 of the smartphone 50, without directly touching the smartphone 50.

[0067] Furthermore, according to this embodiment, the user can view the required display image on the touch panel 51 by operating the stove operation panel 13 without operating the touch panel 51 of the smartphone 50. This improves the convenience of operation and the viewability of the cooking recipe.

[0068] Furthermore, according to this embodiment, the user can input instructions to the gas stove 1 regarding the cooking recipe displayed on the touch panel 51 of the smartphone 50 and change the display image by operating the stove operation panel 13 without operating the smartphone 50, thereby allowing the user to recognize that the input of instructions to the gas stove 1 is being executed reliably.

[0069] Furthermore, according to this embodiment, the user cannot switch from the stove operation mode to the smartphone operation mode unless he or she operates the "smartphone operation" switch 36, which is the switching unit, so it is possible to reliably prevent instructions to the gas stove 1 or changes to the display image on the touch panel 51 from being executed due to erroneous operation.

[0070] Therefore, according to the present embodiment, it is possible to provide a cooking system that is easy for a user to use when performing automatic cooking corresponding to a cooking recipe, and a cooking appliance that constitutes this cooking system.

[0071] (Other embodiments) (1) In the above embodiment, a gas stove is used as the cooking appliance. However, the present invention can be applied to other cooking appliances such as a gas grill, an electric grill, an oven, an induction cooking appliance, etc.

[0072] (2) In the above embodiment, a smartphone is used as the external terminal. However, the present invention can also be applied to other external terminals such as a mobile phone, a tablet, or a personal computer.

[0073] (3) In the above embodiment, the cooking recipe data is acquired from an external server. However, the cooking recipe data may be stored in advance in an external terminal.

[0074] (4) In the above embodiment, the stove operation panel is provided with an operation switch that can be used for both the stove operation mode and the smartphone operation mode. However, an operation switch dedicated to the smartphone operation mode may be provided.

[0075] (5) In the above embodiment, the image is scrolled up and down. However, the image may be scrolled left and right, or the direction of the scroll may be set arbitrarily, depending on the format of the displayed image. The speed of the automatic scroll may be changed arbitrarily, the image may be stopped when a specific operation button is displayed, or the image may be automatically scrolled for a certain period of time.
