[0012] [Embodiment 1] An embodiment of the present invention will be described in detail below. Fig. 1 is a perspective view of the cooking device 1 of this embodiment with the front door 12 closed, as viewed from diagonally above the front. Fig. 2 is a perspective view of the cooking device 1 shown in Fig. 1 with the front door 12 open, as viewed from diagonally below right. Fig. 3 is a perspective view of the cooking device 1 shown in Fig. 1 with the front door 12 open, as viewed from diagonally below right.

[0013] (Overview of Cooker 1) 1 to 3, cooking appliance 1 is, for example, a microwave oven, and has an operation panel (reception unit) 11 at the top of the front face, and a front door 12 below operation panel 11. Front door 12 is a door that opens and closes heating chamber 13 provided behind front door 12, and covers front opening 13b of heating chamber 13 when closed. In this embodiment, front door 12 is of a side-opening type that rotates around the end on the left side as viewed from the front, and has a handle 14 near the right end.

[0014] The operation panel 11 is provided on the front surface of the control frame (board housing section) 15, and the front position of the operation panel 11 is substantially the same as the front position of the front door 12 in the front-rear direction of the cooking appliance 1.

[0015] Inside the control frame 15, a control board (not shown) is provided that controls the display unit of the operation panel 11 and accepts user operations on the input keys and the like.

[0016] (Reader 16) 4 is a vertical cross-sectional view of the control frame 15 showing the installation state of the reading device 16. FIG.

[0017] As shown in Fig. 4, control frame 15 is provided so as to protrude forward from cooking appliance 1. Reading device 16 is attached to the underside of reading device board (circuit board) 17, and is provided at the bottom inside control frame 15. Reading device board 17 is equipped with a drive circuit for reading device 16. That is, reading device 16 is installed outside heating chamber 13, above front opening 13b of heating chamber 13 (on the top wall 13a side), and is installed so as to have reading area 19 below the installation position.

[0018] The reading device 16 is, for example, a barcode reader, and is configured to read an information code (for example, a barcode) attached to the food to be heated in the cooking appliance 1 or to a container for the food.

[0019] As shown in FIG. 5, the area below the reader 16 is a reading area 19, and the control frame 15 has a transparent reading window 18 in the lower wall portion facing the reader 16.

[0020] The reading area 19 of the reading device 16 is indicated by, for example, red light so that the user can visually recognize the reading area 19. This red light is emitted by a reading area illumination unit 21 (see FIG. 7). For example, a red LED (Light Emitting Diode) is used as the reading area illumination unit 21. Note that the light indicating the reading area 19 is not limited to red, and may be other light visible to the user, such as a laser. Furthermore, the number of red LEDs may be one or more.

[0021] 2 and 3, the reading window 18 is provided at the center of the front opening 13b of the heating chamber 13 in the width direction (left and right direction).

[0022] (Information Code) FIG. 6(a) is an explanatory diagram showing an example of an information code consisting of a two-dimensional code (QR (Quick Response) Code (registered trademark)), and FIG. 6(b) is an explanatory diagram showing an example of an information code consisting of a one-dimensional barcode.

[0023] The information code is information indicating the type of food and is attached to the food or its container by, for example, printing or a sticker. The information code is information indicating the type of food, for example, that the food is a bento (or even a type of bento) or that the food is a rice ball (or even a type of rice ball).

[0024] The information code may be, for example, a two-dimensional code as shown in (a) of Figure 6, or a one-dimensional barcode as shown in (b) of Figure 6. Note that the information code is not limited to a barcode or the like as long as it can indicate the type of food.

[0025] The operation panel 11 displays a guidance display 20 for the user to enable the reader 16 to smoothly read the information code. For example, the guidance display 20 may say, "Open the door and hold the information code over the red light." Alternatively, the guidance display 20 may say, "Open the door and hold the red light over the information code." Note that these guidance displays 20 are merely examples and are not particularly limited to these.

[0026] The position where the guidance display 20 is displayed is not limited to a position approximately in the center of the operation panel 11, but may be any position on the operation panel 11, or may be a position other than the operation panel 11 (in front of the cooking appliance 1) as long as it can guide the user through the operation of reading the information code using the reading device 16. A preferred position that improves usability for the user is a position on the operation panel 11 that is sure to be noticeable when operating the cooking appliance 1. Furthermore, a position near (above) the reading window 18 is even more preferable.

[0027] (Guide sign) The guidance display 20 is realized by printing on the operation panel 11 content that guides the user on how to operate the device. For example, a sticker with the guidance display 20 printed on it may be affixed to the operation panel 11. However, the method of realizing the guidance display 20 is not limited to printing on the operation panel 11. Alternatively, the operation panel 11 may be provided with a liquid crystal panel, and the guidance display 20 may be displayed on the liquid crystal panel. In this case, the backlight of the liquid crystal panel is controlled to be turned on in conjunction with the opening and closing of the front door 12. For example, when the front door opening / closing detection unit 25 ( FIG. 7 ) detects that the front door 12 is open, the backlight of the liquid crystal panel on which the guidance display 20 is displayed is turned on in conjunction with the opening of the front door 12. This makes the guidance display 20 easier for the user to see. Alternatively, the content of the guidance display 20 may be notified by voice in addition to the display of the guidance display 20. In this case, even users who have difficulty reading the characters displayed on the guidance display 20 can confirm the information by voice, allowing for smooth operation.

[0028] (Control device) 7 is a block diagram showing the configuration of a control device provided in the cooking appliance 1. The control device includes a control unit 22 that controls the operation of the cooking appliance 1. The control unit 22 is made up of, for example, a microcomputer, and has a CPU (Central Processing Unit), ROM (Read Only Memory), and RAM (Random Access Memory).

[0029] 7, control unit 22 is connected to operation panel 11, heating operation unit 23, reading device 16, reading area illumination unit 21, reading result notification unit 24, front door open / close detection unit 25, heating information change unit 26, memory (storage unit) 32, and heating information change table 33. Front door open / close detection unit 25 is made up of, for example, a switch that turns on when front door 12 is closed, and detects whether front door 12 is open or closed.

[0030] The heating operation unit 23 is an operation unit, such as a microwave output device or a heater, that heats the food placed in the heating chamber 13. The reading result notification unit 24 is a buzzer or a sound generating unit that is controlled by the control unit 22 and notifies the user of the success or failure of the reading of the information code by the reading device 16.

[0031] The control unit 22 can communicate with the server 31, for example, using an internet line. Heating information corresponding to various types of food is registered in the server 31. The control unit 22 acquires heating information corresponding to the type of food from the server 31, which is acquired by the reading device 16 reading the information code, and controls the heating operation unit 23 so that the food is heated in accordance with the acquired heating information. The heating information corresponding to the type of food may be stored in the cooking appliance 1 itself. In this case, the cooking appliance 1 does not need to communicate with the server 31.

[0032] The control unit 22 also controls the operation of the read result notification unit 24 to notify the user of the success or failure of the reading of the information code by the reading device 16.

[0033] Furthermore, memory 32 stores heating information included in the information code read by reader 16. As a result, for a food item whose information code has been read once, the heating information is registered in memory 32 of cooker 1, eliminating the need to acquire heating information each time the information code is read from outside cooker 1. Therefore, when one information code is read by reader 16, and the food item identified by that information code is stored in memory 32, control unit 22 reads out the heating information associated with that food item. Control unit 22 then performs cooking based on the heating information.

[0034] When multiple information codes are read by reader 16, heating information change unit 26, instead of obtaining heating information corresponding to each information code, obtains changed heating information corresponding to the multiple information codes by referring to heating information change table 33. Control unit 22 performs cooking based on the heating information changed by heating information change unit 26.

[0035] Appropriate heating information corresponding to a combination of multiple information codes is pre-registered in the heating information change table 33. For example, if two foods are rice balls, appropriate heating information (500 W, 1 minute 20 seconds) is registered. This is a longer heating time than the heating information (500 W, 1 minute) for one rice ball.

[0036] Furthermore, when the two foods are of different types, for example, when a rice ball and a boxed lunch are combined, appropriate heating information (500W, 2 minutes 20 seconds) is registered in the heating information change table 33. This is a longer heating time than the heating information (500W, 2 minutes) for a single boxed lunch. In this way, the heating information is changed to something different from the heating information for any of the foods of different types (information codes).

[0037] In this way, appropriate heating information for each combination of multiple foods is pre-registered in the heating information change table 33, and the heating information change unit 26 can obtain appropriate heating information by searching the heating information change table 33 for each combination of multiple foods. Although the above description deals with cases where there are one or two types of food, the heating information change table 33 may also register heating information corresponding to combinations of three or more foods.

[0038] In addition, the control unit 22 may receive heating information corresponding to a combination of multiple foods from the server 31 using an internet connection, store it in the heating information change table 33, and the heating information change unit 26 may use that information to obtain the heating information.

[0039] In addition, multiple programs corresponding to multiple food combinations may be stored in memory 32, and control unit 22 may fetch and execute the instruction codes of the programs corresponding to multiple food combinations, thereby cooking the food with appropriate heating information.

[0040] (Operation of cooking device 1) In the above configuration, the operation of the cooking device 1 will be described below. Here, a case where the cooking device 1 is used to heat a rice ball or a boxed lunch with an information code attached to the top surface of the container will be described.

[0041] First, the user checks the guidance display 20 on the operation panel 11 (for example, "Open the door and hold the information code over the red light"). Then, the user opens the front door 12 in accordance with the guidance display 20. When the front door open / close detection unit 25 detects that the front door 12 is open, the control unit 22 activates the reading device 16 and the reading area illumination unit 21.

[0042] Next, the user follows the guide display 20 on the operation panel 11 and moves the rice ball or lunch box so that the information code is in the reading area 19 of the reading device 16 (so that the red light hits the information code).

[0043] Through this operation, the reader 16 reads the information code attached to the rice ball or bento. When the reader 16 successfully reads the information code, the control unit 22 notifies the user of the reading result via the reading result notification unit 24. In this case, the reading result notification unit 24 may, for example, emit a continuous beep, or emit a voice message saying "The information code has been successfully read," or both.

[0044] In this embodiment, it is assumed that a plurality of information codes are read, such as a rice ball and a boxed lunch, etc. In this case, the read result is notified each time a plurality of information codes are read.

[0045] When the user is notified by the read result notification unit 24 that the multiple information codes have been successfully read, he or she places the rice balls or lunch boxes inside the heating chamber 13, closes the front door 12, and presses the start button on the operation panel 11.

[0046] On the other hand, if the reading device 16 fails to read the information code, the control unit 22 notifies the user of the reading result by the reading result notification unit 24. In this case, the operation of the reading result notification unit 24 is, for example, to emit an intermittent sound such as "beep, beep, beep," to emit a voice saying "reading of the information code has failed," or to do both.

[0047] When the user is notified by the read result notification unit 24 that the information code has not been read, he or she moves the rice ball or lunch box again so that the information code is in the reading area 19 of the reader 16 (so that the red light hits the information code). As a result, if the information code is successfully read, the operation is as described above.

[0048] 8 is a flowchart for explaining the processing procedure of the cooking device 1 according to the first embodiment of the present invention. As described above, first, the reader 16 reads the information code attached to the food (S1). Then, the control unit 22 determines whether or not a plurality of information codes have been read by the reader 16 (S2).

[0049] If only one information code is read (S2, No), control unit 22 obtains heating information corresponding to that information code from memory 32 (S4) and controls heating operation unit 23 to cook the food (S5).

[0050] If two or more information codes are read (S2, Yes), heating information change unit 26 acquires changed heating information corresponding to the combination of the multiple information codes from heating information change table 33 (S3). Then, control unit 22 controls heating operation unit 23 according to the changed heating information to cook the food (S5).

[0051] For example, if the changed heating information is 500 W for 30 seconds, the control unit 22 may display several variations, such as 500 W for 25 seconds or 500 W for 35 seconds, on the guidance display 20, allowing the user to select the heating information they prefer. In this way, cooking can be performed at a higher or lower temperature than the set temperature, further improving user convenience.

[0052] As described above, according to the cooking device of the first embodiment of the present invention, when multiple information codes are read by the reading device 16, the heating information changing unit 26 obtains heating information corresponding to the combination of the multiple information codes from the heating information changing table 33. Therefore, even in the case of a combination of rice balls and boxed lunches, for example, cooking can be performed using appropriate heating information, making it possible to provide a cooking device that is easy for users to use.

[0053] [Embodiment 2] The functional configuration of the cooking device 1 according to the second embodiment of the present invention is similar to the functional configuration of the cooking device 1 according to the first embodiment of Fig. 7. Therefore, detailed description of the overlapping configurations and functions will not be repeated.

[0054] In the first embodiment, when multiple information codes are read by the reading device 16, the heating information change unit 26 changes the heating information, but if the information code of one food item is read multiple times by mistake, incorrect heating information will be set. In the cooking device 1 according to the second embodiment of the present invention, even if the information code of one food item is read multiple times by mistake, appropriate heating information can be set and cooking can be performed.

[0055] In this embodiment, the information code includes the serial number of the food product in addition to the type of food product. The control unit 22 obtains and compares the serial numbers from the multiple information codes read by the reading device 16 to determine whether the information code of the same food product has been read multiple times.

[0056] 9 is a flowchart for explaining the processing procedure of the cooking device 1 according to the second embodiment of the present invention. First, the reader 16 reads the information code attached to the food (S11). Then, the control unit 22 determines whether or not a plurality of information codes have been read by the reader 16 (S12).

[0057] If only one information code is read (S12, No), control unit 22 obtains heating information corresponding to that information code from memory 32 (S15) and controls heating operation unit 23 to cook the food (S16).

[0058] If two or more information codes are read (S12, Yes), it is determined whether the serial numbers included in the information codes are the same (S13). If the serial numbers are the same (S13, Yes), it is determined that the information code for the same food item has been read multiple times, and control unit 22 obtains heating information corresponding to the information code from memory 32 (S15) and controls heating operation unit 23 to cook the food (S16).

[0059] If the serial numbers included in the information codes are not the same (S13, No), heating information change unit 26 acquires heating information corresponding to the combination of the multiple information codes from heating information change table 33 (S14). Then, control unit 22 controls heating operation unit 23 in accordance with the heating information to cook the food (S16).

[0060] As described above, according to the cooking device 1 of the second embodiment of the present invention, when the serial numbers included in multiple information codes are the same, the control unit 22 processes the information codes as if only one information code has been read. This prevents incorrect heating information from being set, making it possible to provide a cooking device that is easy for users to use.

[0061] [Embodiment 3] The functional configuration of the cooking device 1 according to the third embodiment of the present invention is similar to the functional configuration of the cooking device 1 according to the first embodiment of Fig. 7. Therefore, detailed description of the overlapping configurations and functions will not be repeated.

[0062] In the first embodiment, when multiple information codes are read by the reading device 16, the heating information change unit 26 changes the heating information. However, in the case of a food combination that may not be heated properly, there is a possibility that one of the foods may become too hot. In the cooking device 1 according to the third embodiment of the invention, when a combination does not satisfy a predetermined condition, cooking is not performed and a warning is given to the user by an alarm sound or the like. For example, if the multiple information codes are a combination of a bento box and soup, the soup will become too hot if the heating time is long. In the case of such a combination, cooking is not performed.

[0063] In this embodiment, for example, combinations that do not satisfy predetermined conditions, i.e., food combinations that may not be properly heated, are stored in memory 32 or the like. Then, when the combination of multiple information codes read by reader 16 matches a food combination stored in memory 32, control unit 22 warns the user by outputting an alarm sound without performing cooking using heating operation unit 23. Note that in this embodiment, control unit 22 outputs the alarm sound using read result alarm unit 24.

[0064] Furthermore, if the combination of multiple information codes read by the reader 16 is not registered in the heating information change table 33, the control unit 22 may determine that the combination does not satisfy the predetermined condition.

[0065] 10 is a flowchart for explaining the processing procedure of the cooking device 1 according to the third embodiment of the present invention. First, the reader 16 reads the information code attached to the food (S21). Then, the control unit 22 determines whether or not a plurality of information codes have been read by the reader 16 (S22).

[0066] If only one information code is read (S22, No), control unit 22 obtains heating information corresponding to that information code from memory 32 (S25) and controls heating operation unit 23 to cook the food (S26).

[0067] If two or more information codes are read (S22, Yes), it is determined whether the combination of information codes matches the food combination that may not be properly heated stored in memory 32 (S23). If the food combination is one that may not be properly heated (S23, Yes), control unit 22 does not perform cooking using heating operation unit 23, but instead causes read result notification unit 24 to output a notification sound to issue a warning (S27), and the process ends.

[0068] If the food combination is not one that may not be properly heated (S23, No), the heating information change unit 26 acquires heating information corresponding to the combination of multiple information codes from the heating information change table 33 (S24). Then, the control unit 22 controls the heating operation unit 23 in accordance with the heating information to cook the food (S26).

[0069] As described above, according to the cooking device 1 of the third embodiment of the present invention, when a combination of multiple information codes matches a combination of foods that may not be properly heated and is stored in the memory 32, cooking is not performed by the heating operation unit 23, and an alarm is output by the read result notification unit 24 to warn the user. This prevents one of the foods from becoming too hot, making it possible to provide a cooking device that is easy for the user to use.

[0070] [Software implementation example] The control block of the cooking appliance 1 (particularly the control unit 22) may be realized by a logic circuit (hardware) formed in an integrated circuit (IC chip) or the like, or may be realized by software.

[0071] In the latter case, the cooking appliance 1 includes a computer that executes instructions of a program, which is software that realizes each function. This computer includes, for example, at least one processor (controller) and at least one computer-readable recording medium storing the program. The object of the present invention is achieved when the processor in the computer reads and executes the program from the recording medium. The processor may be, for example, a CPU. The recording medium may be a "non-transitory tangible medium," such as a ROM, tape, disk, card, semiconductor memory, or programmable logic circuit. The cooking appliance 1 may also include a RAM for expanding the program. The program may be supplied to the computer via any transmission medium capable of transmitting the program (such as a communication network or broadcast waves). Note that one aspect of the present invention may also be realized in the form of a data signal embedded in a carrier wave, in which the program is embodied by electronic transmission.

[0072] 〔summary〕 A heating cooker according to aspect 1 of the present invention comprises a heating chamber, a reading device that reads information codes of food, a heating information change unit that, if there are multiple information codes of food read by the reading device, changes the heating information to heating information different from any of the heating information corresponding to the multiple information codes depending on the combination of the multiple information codes, and a control unit that controls the heating cooking of food in the heating chamber using the heating information changed by the heating information change unit.

[0073] According to the above configuration, the heating information change unit changes the heating information according to the combination of multiple information codes, so that even in the case of a combination of rice balls and bento lunches, for example, cooking can be performed using appropriate heating information, making it possible to provide a heating cooker that is easy for users to use.

[0076] In a heating cooker according to aspect 3 of the present invention, in the above-mentioned aspect 1 or 2, the information code includes the serial number of the food, and if the serial numbers included in the multiple information codes are the same, the control unit controls the heating and cooking of the food in the heating chamber using heating information corresponding to the information code.

[0077] According to the above configuration, incorrect heating information is not set, and it is possible to provide a cooking device that is easy for the user to use.

[0078] In a cooking device according to aspect 4 of the present invention, in any of aspects 1 to 3 above, the control unit outputs a warning to the user if there are multiple information codes of the food read by the reading device and the combination of the multiple information codes does not satisfy a predetermined condition.

[0079] According to the above configuration, it is possible to provide a cooking device that is user-friendly, since it is possible to prevent one food from becoming too hot.

[0080] In a heating cooker according to aspect 5 of the present invention, in the above aspect 2, if there are multiple information codes of the food read by the reading device and the combination of the multiple information codes is not in the heating information change table, the control unit outputs a warning to the user.
