[0007] Patent Document 2: Japanese Patent Application Publication No. 2014-202414 Summary of the invention

[0008] The present disclosure provides a heating cooker that determines whether to heat an object that is not suitable for heating based on an index indicating the degree to which the object is not suitable for heating. The index is determined based on the type of the object. Hereinafter, the index is referred to as the heating unsuitability.

[0009] The heating cooker disclosed in the present invention comprises a heating chamber, a detector and a control unit. The heating chamber can accommodate objects. The detector is arranged in the heating chamber. The control unit determines whether the object is a heatable object or a non-heatable object based on the detection information detected by the detector. When the object is determined to be a heatable object, the control unit heats the object accommodated in the heating chamber. When the object is determined to be a non-heatable object, the control unit avoids heating according to the heating unsuitability of the object.

[0016] (Insights, etc. that form the basis of this disclosure)

[0017] In the past, there was a microwave oven that had the following technology: when heating an object, the type of the object stored in the heating chamber was determined based on an image captured in the heating chamber, and the object was automatically heated based on the result. If the object was determined to be unsuitable for heating based on the image, the microwave oven avoided heating.

[0018] However, in this technology, even if the object is actually a heatable object, it cannot be heated if it is erroneously determined to be a non-heatable object. The inventors of the present application have devised the subject matter of the present disclosure in order to solve this problem.

[0019] The present disclosure provides a heating cooker capable of improving the safety and convenience of the heating cooker by avoiding heating according to the heating unsuitability of an object.

[0020] Hereinafter, the embodiments will be described in detail with reference to the drawings, but for example, detailed description of known matters or repeated description of substantially the same configuration may be omitted.

[0021] (Implementation Method 1)

[0022] Hereinafter, Embodiment 1 of the present disclosure will be described with reference to the drawings.

[0023] [1-1. Structure]

[0024] [1-1-1. Structure of the heating cooker]

[0025] Figure 1 2 is a perspective view of the heating cooker 1 according to the present embodiment. Figure 1As shown, the heating cooker 1 includes a box-shaped housing 10. An opening 11 is formed on the front surface of the housing 10. The housing 10 includes a heating chamber 12 disposed therein and capable of storing an object 2. The heating chamber 12 includes an illumination unit 13 disposed on the inner side. The illumination unit 13 illuminates the entire interior of the heating chamber 12 from the inner side.

[0026] The heating chamber 12 has a camera 14 disposed on the inner upper surface. By disposing the camera 14 on the inner upper surface of the heating chamber 12, the entire interior of the heating chamber 12 can be photographed.

[0027] The cooking device 1 is configured to detect heating information related to the object 2 based on image information of the object 2 accommodated in the heating chamber 12 captured by the camera 14. The camera 14 can also read code information such as a barcode or QR code (registered trademark) provided on the object 2.

[0028] A door 15 that can be opened and closed left and right around one side of the opening 11 is mounted on the front surface of the housing 10. An operation panel 20 including a display unit 21 and an operation unit 22 is arranged above the opening 11 and the door 15 on the front surface of the housing 10.

[0029] Figure 2 20 is a top view of the operation panel 20. Figure 2 As shown, the operation panel 20 includes a display unit 21 and an operation unit 22. The display unit 21 includes an LED (Light Emitting Diode) display element for displaying heating control information. The operation unit 22 includes numeric buttons for setting various cooking menus and special operations and a start button for starting the heating process of the object 2.

[0030] [1-1-2. Control structure]

[0031] Figure 3 1 is a block diagram showing the functional structure of the heating cooker 1 of this embodiment. Figure 3 As shown, the cooking device 1 includes a control unit 30 and a storage unit 34. The control unit 30 includes a processor such as a CPU (Central Processing Unit) and a semiconductor memory. The control unit 30 executes various processes by the processor executing processes according to a control program stored in the semiconductor memory.

[0032] The control unit 30 includes a recognition unit 31, a determination unit 32, and an operation control unit 33. The storage unit 34 stores, for example, image information of the object 2, code information, and size information and weight information of the object 2.

[0033] The storage unit 34 stores heating unsuitability and processing to be performed for each type of object 2. For example, the storage unit 34 stores information that the heating unsuitability of a PET (Polyethylene Terephthalate) bottle is high and heating should be avoided, and information that the heating unsuitability of Worcestershire sauce is low and only the user is notified.

[0034] The code information includes information on whether the object 2 is a heatable object or an unheatable object. When the object 2 is an unheatable object, the code information includes the heating unsuitability of the object 2, the heating output and the heating time for the type of the object 2, etc. The information on the heating output and the heating time for the type of the object 2 is, for example, heating for 1 minute and 30 seconds at a heating output of 1200 W.

[0035] The control unit 30 is connected to the notification unit 24, the operation unit 22, the heating unit 25, the camera 14, and the sensors 35. The notification unit 24 includes a display unit 21 and a sound generating unit 23. The sound generating unit 23 includes, for example, an element for generating sound, such as a buzzer or a speaker, which is arranged in the heating cooker 1. The heating unit 25 is an element capable of heating the object 2. The heating unit 25 includes, for example, a magnetron for dielectric heating and a sheathed heater for radiation heating.

[0036] The control unit 30 is connected to the operation unit 22 and the heating unit 25. The control unit 30 receives the operation information of the operation unit 22 from the operation unit 22. The control unit 30 (specifically, the operation control unit 33) controls the heating unit 25 based on the operation information of the operation unit 22. The operation control unit 33 controls the camera 14, the notification unit 24, and the heating unit 25.

[0037] In this embodiment, the camera 14 functions as a main sensor, and the sensors 35 function as other sensors. The sensors 35 include a temperature sensor, a weight sensor, and an infrared sensor.

[0038] The control unit 30 receives the image information of the object 2 captured by the camera 14 . The control unit 30 receives the detection information detected by the sensors 35 .

[0039] Hereinafter, the detection information detected by the sensors 35 will be referred to as the detection information of the sensors 35. The detection information of the sensors 35 includes, for example, the internal temperature of the heating chamber 12, the weight of the object 2, and the temperature of the object 2.

[0040] The detector of this embodiment includes the camera 14 and the sensors 35. That is, in this embodiment, the detection information detected by the detector refers to both or one of the image information of the object 2 and the detection information of the sensors 35.

[0041] In the control unit 30, the recognition unit 31 recognizes the object 2 stored in the heating chamber 12 based on the image information of the object 2. The determination unit 32 compares the object 2 recognized by the recognition unit 31 with the image information of the object 2 stored in the storage unit 34. Thus, the determination unit 32 determines whether the object 2 recognized by the recognition unit 31 and included in the image is a heatable object or a non-heatable object.

[0042] For example, when the judgment criterion of the judgment unit 32 for a PET bottle is set to a probability of "90%", if the judgment unit 32 judges that the probability that the object 2 recognized by the recognition unit 31 is a PET bottle is "95%," the object 2 is judged to be a PET bottle. The judgment criterion of the judgment unit 32 is a threshold value (%) for the probability of being the judgment result of the judgment unit 32. The storage unit 34 stores the predetermined judgment criterion.

[0043] When it is determined that the image contains multiple objects 2, the determination unit 32 applies the respective determination criteria to the multiple objects 2. For example, the determination criteria for the certainty of Worcestershire sauce and lunchbox are assumed to be "50%" and "90%", respectively. In this case, when the determination unit 32 determines that the probability of lunchbox is "95%" and the probability of Worcestershire sauce is "55%", it is determined that the multiple objects 2 are lunchbox and Worcestershire sauce.

[0044] Since Worcestershire sauce often adheres to the upper surface of the bento, according to this embodiment, the bento and the Worcestershire sauce adhered to the upper surface of the bento can be distinguished.

[0045] In addition, the determination unit 32 may determine the probability (%) associated with the type of the object 2 by artificial intelligence, machine learning, deep learning, etc. These thresholds based on the determination of the determination unit 32 can be set arbitrarily.

[0046] When determining whether the object 2 is a heatable object or a non-heatable object, the camera 14 may read code information provided to the object 2, and the determination unit 32 may obtain information about the object 2 stored in the storage unit 34 based on the code information.

[0047] Based on the code information and the information of the object 2, the determination unit 32 can determine whether the object 2 is a heatable object or an unheatable object, and if the object 2 is an unheatable object, whether its heating unsuitability is high or low.

[0048] When acquiring the image information of the object 2 , the acquisition of the image information and the determination by the determination unit 32 can be performed simultaneously by acquiring the code information.

[0049] First, the judgment unit 32 can judge whether the object 2 is an unheatable object based on the image information of the object 2, and whether the heating unsuitability is high or low if the object 2 is an unheatable object. Thereafter, the judgment unit 32 can verify whether the judgment is correct or incorrect based on the code information.

[0050] The determination unit 32 can obtain detection information such as temperature information and weight information of the object 2 detected by the sensor 35 together with the image information of the object 2. Based on this information, the determination unit 32 can identify the type of the object 2, determine whether the object 2 is an unheatable object, and determine the heating unsuitability if the object 2 is an unheatable object.

[0051] In this case, the judgment unit 32 can make a judgment using both the image information of the object 2 and the detection information of the sensor 35. In order to supplement the judgment based on the image information of the object 2, the judgment unit 32 can use the detection information of the sensor 35. By making a judgment on the object 2 based on multiple information as described above, the judgment accuracy of the judgment unit 32 can be improved.

[0052] The sensors 35 include, for example, infrared sensors, temperature detection sensors such as thermistors, sensors for detecting incident waves and reflected waves of microwaves, and weight sensors.

[0053] The determination unit 32 makes an initial determination of the type of the object 2 based on the image information. Then, the determination unit 32 can determine whether to use other information and which information to use among other information based on the initial determination.

[0054] For example, the determination unit 32 may determine which information to use as the second information based on the initial determination, and determine the third information based on the determination using the second information.

[0055] When a plurality of results are obtained by determination based on the image information and code information of the object 2 and the detection information of the sensor 35 , the determination unit 32 may adopt the largest number of determination results that are the same.

[0056] The determination unit 32 can implement various methods for determining the object 2 using the image information. For example, the determination unit 32 can use a plurality of deep learning methods or learning models, or deep learning and detection based on image processing.

[0057] When the determination unit 32 cannot determine the type of the object 2 using any information, it may be considered that the determination of the object 2 has failed. By such processing, the recognition rate in determining the type of the object 2 can be improved.

[0058] The determination unit 32 may use other information only when determining that the object 2 is an unheatable object after acquiring the image information.

[0059] When the determination unit 32 determines that the object 2 is not an unheatable object, it is possible to immediately heat the object 2. In this case, by omitting the determination of the heating unsuitability, the processing speed can be increased.

[0060] When using image information, the judgment unit 32 can make a judgment based on a sticker or mark attached to the object 2, the overall shape of the object 2, the partial shape of the object 2, or the color information of the object 2. By using a part of the image information instead of the entirety, the judgment accuracy can be improved and the processing time can be shortened.

[0061] When the determination unit 32 determines that the object 2 is not heatable, the control unit 30 determines whether to heat it according to its heating unsuitability. For example, the heating unsuitability is high for objects 2 that are not suitable for dielectric heating, such as metal canned beverages, PET bottled beverages, and eggs.

[0062] For example, if the object 2 is a lunch box or the like and a bag containing condiments such as Worcestershire sauce, soy sauce, or mayonnaise is attached to the outside thereof, the bag containing the condiments needs to be removed from the object 2 when heating. Such an object 2 is equivalent to an unheatable object and has a low degree of unsuitability for heating.

[0063] The heating unsuitability of the object 2 is not preset and can be set arbitrarily by the user.

[0064] The control unit 30 avoids heating when the heating unsuitability of the object 2 is high, and on the other hand, notifies the user through the notification unit 24 when the heating unsuitability of the object 2 is low. In this case, the notification unit 24 performs visual notification using the display unit 21 and audio notification using the audio unit 23 upon receiving an instruction signal from the control unit 30.

[0065] The control unit 30 reminds the user to pay attention to the object 2 with a low heating unsuitability, and avoids heating the object 2 with a high heating unsuitability.

[0066] Even when the object 2 is judged to be an unheatable object and its heating unsuitability is high, the control unit 30 can forcibly heat it under the prescribed conditions. Thus, heating can be performed even when the judgment of the heating unsuitability of the object 2 is wrong, which can improve the operability of the user. Hereinafter, forced heating is referred to as forced heating.

[0067] When forced heating is performed, for example, the output may be lowered compared to normal. In order to enable forced heating, the threshold value for determining heating unsuitability may be changed. Depending on the type of the object 2, forced heating may not be performed.

[0068] For forced heating, for example, the operation unit 22 may have a button capable of forced heating. For example, forced heating may be performed by performing a specific operation on the operation unit 22.

[0069] In this case, the notification unit 24 may be used to notify the user that forced heating is being performed. In this case, the notification unit 24 may be used to provide a notification different from that of normal heating.

[0070] During the forced heating, the forced heating may be terminated by the user performing a specific operation on the operation unit 22. The forced heating may also be terminated automatically when a predetermined heating time has elapsed.

[0071] [1-2. Action]

[0072] Next, the operation of the cooking device 1 according to the present embodiment will be described. Figure 4 1 is a flowchart showing the operation of the heating cooker 1 according to the present embodiment. Figure 4 As shown, when the cooking device 1 starts operating, it acquires both or one of the image information of the object 2 and the detection information of the sensor 35 (step SA1). Based on the information, the control unit 30 recognizes the type of the object 2 (step SA2).

[0073] The control unit 30 determines whether the object 2 is a heatable object or an unheatable object based on the image information and the detection information (step SA3). The processing of step SA3 may be omitted.

[0074] When it is determined that the object 2 is an unheatable object (YES in step SA3 ), the control unit 30 determines whether the degree of heating unsuitability of the object 2 is higher than a threshold value (step SA4 ).

[0075] When the heating unsuitability is higher than the threshold value (YES in step SA4 ), control unit 30 causes notification unit 24 to notify that the heating unsuitability is higher than the threshold value (step SA5 ), and then avoids heating of object 2 (step SA6 ).

[0076] When it is determined that the object 2 is not an unheatable object (No in step SA3), the control unit 30 starts heating the object 2 (step SA8). The control unit 30 determines whether a predetermined heating time has passed (step SA9). When the predetermined heating time has passed (Yes in step SA9), the control unit 30 ends the heating (step SA10).

[0077] When it is determined that the degree of unsuitability in heating is not higher than the threshold value (NO in step SA4 ), control unit 30 causes notification unit 24 to notify that the degree of unsuitability in heating is lower than the threshold value (step SA7 ).

[0078] In this case, the control unit 30 can open and close the door 15 through the notification of the notification unit 24, for example, to prompt the user to remove the bag of condiments such as Worcestershire sauce and mayonnaise attached to the outside of the lunch box.

[0079] When it is determined that the degree of heating unsuitability is not higher than the threshold value (NO in step SA4), control unit 30 may start heating different from normal heating after notification by notification unit 24 (step SA8).

[0080] For example, for a "grilled meat bento", it is assumed that the heating is set to be performed at a normal heating output of 1200 W and a heating time of 1 minute and 30 seconds. In this case, when a bag containing seasoning is attached to the bento, the control unit 30 may perform heating at a predetermined heating output lower than normal and a predetermined heating time shorter than normal, or at least one of the two. The predetermined heating output lower than normal and the predetermined heating time shorter than normal are, for example, 600 W and 45 seconds, respectively.

[0081] When a predetermined heating time has elapsed (step SA9 ), control unit 30 ends the heating (step SA10 ).

[0082] In this embodiment, the control unit 30 determines whether to end heating based on the elapse of the heating time (step SA9 ). Alternatively or simultaneously, the control unit 30 may determine whether to end heating based on the temperature information of the object 2 detected by the sensor 35 .

[0083] [1-3. Effects, etc.]

[0084] The cooking device 1 of the present embodiment includes a heating chamber 12 capable of storing an object 2, a detector, and a control unit 30. The detector is disposed in the heating chamber 12. The detector is both or one of the camera 14 and the sensor 35.

[0085] The control unit 30 determines whether the object 2 stored in the heating chamber 12 is a heatable object or an unheatable object based on the detection information detected by the detector. When the object 2 is determined to be a heatable object, the control unit 30 heats the object 2. When the object 2 is determined to be an unheatable object, the control unit 30 avoids heating the object according to the unsuitability of heating the object 2 for an unheatable object.

[0086] According to this embodiment, heating can be avoided when the object 2 is a non-heatable object, and the heating cooker 1 can be appropriately used. When the object 2 is a heatable object, it is not necessary to determine whether the object 2 is a non-heatable object. That is, the processing speed of the control unit 30 can be increased, and the safety and convenience of the heating cooker can be improved.

[0087] In this embodiment, when the object 2 is a non-heatable object and its heating unsuitability is low, the control unit 30 performs a notification process to the user. Thereafter, the control unit 30 heats the object 2 by a normal heating method or by a heating method different from the normal heating method.

[0088] Thus, even if the object 2 is an unheatable object, only the notification process is performed when the heating unsuitability is low, or the object 2 is heated by a heating method different from the usual heating method after the notification process is performed. That is, the heating process can be performed according to the user's judgment, which can improve the convenience of the heating cooker.

[0089] In this embodiment, the control unit 30 determines whether to perform a judgment based on the detection information of the sensor 35 based on the judgment of whether the object 2 is a heatable object or a non-heatable object based on the image information of the object 2. That is, the control unit 30 does not always have to perform all the processing. As a result, the processing speed of the control unit 30 can be increased, and the convenience of the heating cooker can be improved.

[0090] In this embodiment, when the object 2 is judged to be a non-heatable object, the control unit 30 can perform forced heating through the user's operation. Thus, when the control unit 30 mistakenly judges that the object 2 is a non-heatable object, forced heating can be performed according to the user's judgment, which can improve the convenience of the heating cooker.

[0091] In the present embodiment, when forced heating is performed, the control unit 30 notifies the user of the execution of forced heating. Thus, the user can recognize whether forced heating is being performed or normal heating is being performed.

[0092] In the present embodiment, when forced heating is performed, the control unit 30 performs heating different from normal heating. When forced heating is performed, for example, by performing heating at a lower output than normal, the safety and convenience of the cooking device can be improved.

[0093] (Implementation Method 2)

[0094] [2-1. Structure]

[0095] Next, the cooking device 1 according to the second embodiment of the present disclosure will be described.

[0096] The heating cooker 1 of this embodiment has the same structure as the heating cooker 1 of the first embodiment, but performs a process different from that of the first embodiment. Figure 1 to Figure 3 Similarly, detailed description of its elements is omitted.

[0097] [2-2. Action]

[0098] Figure 5 1 is a flowchart showing the operation of the heating cooker 1 of the present embodiment. The present embodiment is different from the first embodiment in that the determination of whether the object 2 is a heatable object or an unheatable object is also performed during the heating process.

[0099] In the cooking device 1 of the present embodiment, when automatic heating is started, image information of the object 2 and detection information of the sensors 35 are acquired (step SB1). Based on these information, the control unit 30 recognizes the type of the object 2 (step SB2).

[0100] The control unit 30 determines whether the object 2 is a heatable object or an unheatable object based on the image information and the detection information (step SB3). The processing of step SB3 may be omitted.

[0101] When it is determined that the object 2 is an unheatable object (YES in step SB3 ), the control unit 30 determines whether the degree of heating unsuitability of the object 2 is higher than a threshold value (step SB4 ).

[0102] When the heating unsuitability is higher than the threshold value (YES in step SB4 ), control unit 30 causes notification unit 24 to notify that the heating unsuitability is higher than the threshold value (step SB5 ), and avoids heating of object 2 (step SB6 ).

[0103] When it is determined that the object 2 is not an unheatable object (No in step SB3), the control unit 30 starts heating the object 2 (step SB8), and moves the process to step SB9. Step SB9 will be described later.

[0104] When determining that the heating unsuitability of the object 2 is not higher than the threshold value (NO in step SB4 ), the control unit 30 causes the notification unit 24 to notify that the heating unsuitability is lower than the threshold value (step SB7 ).

[0105] In this case, the control unit 30 can open and close the door 15 through the notification of the notification unit 24, for example, to prompt the user to remove the bag of condiments such as Worcestershire sauce and mayonnaise attached to the outside of the lunch box.

[0106] When it is determined that the degree of heating unsuitability is not higher than the threshold value (No in step SB4 ), the control unit 30 may start heating different from normal heating after the notification from the notification unit 24 (step SB8 ).

[0107] For example, for a "grilled meat bento", it is assumed that the heating is normally set to be performed at a heating output of 1200 W and a heating time of 1 minute and 30 seconds. In this case, when a bag containing seasoning is attached to the bento, the control unit 30 may perform heating at a predetermined heating output lower than normal and a predetermined heating time shorter than normal, or at least one of the two. The predetermined heating output lower than normal and the predetermined heating time shorter than normal are, for example, 600 W and 45 seconds, respectively.

[0108] When the object 2 is heated, the shape or characteristics of the object 2 may change. If the shape or characteristics of the object 2 change, the result of the determination of whether the object 2 is a heatable object or an unheatable object may change. Even if the determination that the object 2 is an unheatable object does not change, the heating unsuitability of the object 2 may change. In this embodiment, in order to cope with the change in the shape or characteristics of the object 2 caused by heating, the control unit 30 performs the following processing.

[0109] After starting to heat the object 2 (step SB8), the control unit 30 obtains both or one of the image information of the object 2 and the detection information of the sensor 35 (step SB9). The control unit 30 determines whether to stop heating the object 2 (step SB10). That is, the control unit 30 determines whether the object 2 is a heatable object or an unheatable object, and whether the heating unsuitability of the object 2 is higher than a threshold value.

[0110] When the object 2 is determined to be an unheatable object and the heating unsuitability is higher than the threshold value (Yes in step SB10), the control unit 30 stops heating the object 2 (step SB13). At the same time, the control unit 30 causes the notification unit 24 to notify that the heating unsuitability of the object 2 is high.

[0111] When it is determined that object 2 is not an unheatable object, or when it is determined that object 2 is an unheatable object but its heating unsuitability is lower than the threshold value (No in step SB10), the control unit 30 determines whether the prescribed heating time has passed while continuing the heating (step SB11).

[0112] When the predetermined heating time has elapsed (YES in step SB11), control unit 30 ends heating (step SB12). When the predetermined heating time has not elapsed, control unit 30 returns the process to step SB9 (NO in step SB11).

[0113] In this embodiment, the control unit 30 determines whether to end heating based on the elapse of the heating time (step SB11 ). Alternatively or simultaneously, the control unit 30 may determine whether to end heating based on the temperature information of the object 2 detected by the sensor 35 .

[0114] [2-3. Effects, etc.]

[0115] In this embodiment, the control unit 30 uses both or one of the camera 14 and the sensor 35 (detector) to determine whether the heating of the object 2 should be stopped during the heating and cooking of the object 2. When it is determined that the heating of the object 2 should be stopped, the control unit 30 stops the heating and notifies the user of the stop of the heating. Thus, the safety and convenience of the heating cooker 1 can be improved.

[0116] (Other embodiments)
