Description

[Technical Field]

[0001] The technology disclosed in this specification relates to a cooking device. [Background technology]

[0002] Patent Document 1 discloses a cooking device that includes a heating unit for heating an object to be heated and an operation unit for setting a cooking mode. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2020-186880 Summary of the Invention [Problem to be solved by the invention]

[0004] In the cooking appliance of Patent Document 1, the user sets the cooking mode by, for example, manually operating an operation panel provided on the cooking appliance. However, this configuration has the problem that, for example, the setting screen on the operation panel is repeatedly switched, making the operation cumbersome and making it difficult for the user to use. Therefore, instead of operating the operation panel, it is conceivable that the user could specify the cooking mode and setting values ​​by voice, but it is difficult for the user to remember all the patterns of cooking modes and setting values, and it is conceivable that the user's voice instructions would be incomplete.

[0005] This specification provides a technology that enables a cooking device that performs a heating operation based on a user's voice instruction to perform the heating operation even if the user's voice instruction is incomplete. [Means for solving the problem]

[0006] In a first aspect of the present technology, a cooking appliance may include a plurality of heating units capable of heating an object to be heated, a voice acquisition unit capable of acquiring user voices, and a control unit. Each heating unit may be capable of heating the object to be heated through a heating operation specified by a cooking mode and a set value. The voice acquisition unit may be capable of acquiring a heating unit-specific voice that identifies the heating unit, a cooking mode-specific voice that identifies the cooking mode, and a set value-specific voice that identifies the set value. The control unit may be capable of identifying one of the plurality of heating units and of identifying the cooking mode and set value for the heating operation of the identified heating unit based on the heating unit-specific voice, cooking mode-specific voice, and set value-specific voice acquired by the voice acquisition unit. Even if the voice acquisition unit does not acquire at least one of the heating unit-specific voice, cooking mode-specific voice, and setting value-specific voice, the control unit may identify one of the multiple heating units based on at least one of the heating unit-specific voice, cooking mode-specific voice, and setting value-specific voice acquired by the voice acquisition unit, and may identify the cooking mode and setting value for the heating operation at the identified heating unit.

[0007] According to this configuration, even if at least one of the heating unit-specific sound, cooking mode-specific sound, and setting value-specific sound is missing, the heating operation can be performed by specifying the heating unit, cooking mode, and setting value. Therefore, in a cooking device that performs a heating operation based on a user's voice instruction, the heating operation can be performed even if the user's voice instruction is incomplete.

[0008] In a second aspect, in the first aspect described above, when the voice acquisition unit does not acquire a heating unit-specific voice but acquires a cooking mode-specific voice, if it is possible to identify one of the multiple heating units based on the cooking mode-specific voice acquired by the voice acquisition unit, the control unit may identify the heating unit based on the cooking mode-specific voice acquired by the voice acquisition unit.

[0009] With this configuration, even if the heating unit identification sound is insufficient, the heating operation can be performed by identifying the heating unit based on the cooking mode identification sound, thereby improving usability for the user.

[0010] In a third aspect, in the first aspect, when the voice acquisition unit does not acquire a cooking mode identification voice but acquires a setting value identification voice, if the cooking mode can be identified based on the setting value identification voice acquired by the voice acquisition unit, the control unit may identify the cooking mode based on the setting value identification voice acquired by the voice acquisition unit.

[0011] With this configuration, even if the cooking mode specifying sound is insufficient, the heating operation can be performed by specifying the cooking mode based on the setting value specifying sound, thereby improving usability for the user.

[0012] In a fourth aspect, in the third aspect described above, when the voice acquisition unit does not acquire a heating unit-specific voice and a cooking mode-specific voice but acquires a setting value-specific voice, if the heating unit and cooking mode can be identified based on the setting value-specific voice acquired by the voice acquisition unit, the control unit may identify the heating unit and cooking mode based on the setting value-specific voice acquired by the voice acquisition unit.

[0013] With this configuration, even if the heating unit specific sound and cooking mode specific sound are insufficient, the heating operation can be performed by identifying the heating unit and cooking mode based on the heating unit specific sound and setting value specific sound, thereby improving usability for the user.

[0014] In a fifth aspect, in the first aspect, when the voice acquisition unit acquires a cooking mode-specific voice but does not acquire a setting value-specific voice, the control unit may set the setting value in the cooking mode identified based on the cooking mode-specific voice acquired by the voice acquisition unit to the setting value when the previous heating operation was performed in the same cooking mode, or to the setting value set as the initial value for the same cooking mode.

[0015] According to this configuration, when the setting value identification sound is insufficient, the setting value in the cooking mode can be set to the previous setting value or the initial value, which makes the setting less uncomfortable for the user and improves usability for the user.

[0016] In a sixth aspect, in the first aspect described above, the heating cooker may further include an audio output unit that outputs a request sound, which is a sound requesting the user to emit a heating unit identification sound, when the control unit is unable to identify the heating unit.

[0017] According to this configuration, the user can be notified that the heating unit specific sound is insufficient, and the user can be prompted to emit the missing sound, thereby improving usability for the user.

[0018] In a seventh aspect, in the first aspect, the cooking device may further include an operation unit that accepts a user operation to identify the heating unit that will perform a heating operation. When the cooking mode is identified based on the cooking mode identifying sound or the setting value identifying sound acquired by the sound acquisition unit, and the control unit is unable to identify the heating unit, if there are multiple heating units that can execute the identified cooking mode, when the operation unit accepts a user operation to identify the heating unit, the control unit may identify the heating unit identified by the user operation accepted by the operation unit as the heating unit that will perform the heating operation.

[0019] With this configuration, when there are multiple heating units capable of executing the same cooking mode, even if the user does not issue a heating unit identification sound, the heating unit can be identified by user operation on the operation unit, and the heating operation can be executed. This improves usability for the user.

[0020] In an eighth aspect, in any one of the first to seventh aspects, the heating cooker may switch to an audio standby state when the power is turned on, when the audio acquisition unit acquires a predetermined wake-up audio, or when an ignition operation is performed on one of the multiple heating units, and when the heating cooker is in the audio standby state, the audio acquisition unit may be able to acquire at least one of a heating unit-specific audio, a cooking mode-specific audio, and a setting value-specific audio.

[0021] According to this configuration, the voice standby state is switched to at an appropriate timing, which improves usability for the user.

[0022] In a ninth aspect, in any one of the first to eighth aspects, the control unit may be able to identify one of the multiple heating units based on the heating unit-specific sound, cooking mode-specific sound, and setting value-specific sound acquired by the sound acquisition unit, even if the sound acquisition unit acquires the heating unit-specific sound, cooking mode-specific sound, and setting value-specific sound in any order, and may be able to identify the cooking mode and setting value for the heating operation at the identified heating unit.

[0023] According to this configuration, the user can utter the heating unit specific sound, cooking mode specific sound, and setting value specific sound in any order, thereby improving usability for the user.

[0024] In a tenth aspect, the cooking device of the first aspect may further include an operation unit that accepts a user operation to identify the heating unit that will perform a heating operation. When the operation unit accepts a user operation to identify the heating unit before the voice acquisition unit acquires at least one of a heating unit-identifying voice, a cooking mode-identifying voice, and a setting value-identifying voice, the control unit may identify the heating unit identified by the user operation accepted by the operation unit as the heating unit that will perform a heating operation, and then may identify a cooking mode and a setting value for the heating operation in the identified heating unit based on at least one of the cooking mode-identifying voice and the setting value-identifying voice acquired by the voice acquisition unit.

[0025] According to this configuration, even if the heating unit identification sound is insufficient, the heating unit can be identified by the user's operation on the operation unit, and the heating operation can be performed. This improves usability for the user. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0027] (Configuration of cooking device 10) As shown in FIG. 1, the cooking appliance 10 of the embodiment is a built-in gas-fired stove that is incorporated into, for example, a system kitchen. The cooking appliance 10 includes a main body 12, a top plate 14 disposed on top of the main body 12, and three burners 16 (a left burner 16a, a right burner 16b, and a rear burner 16c) exposed from the top plate 14. The left burner 16a is a burner for heating an object to be heated (e.g., a cooking vessel). A gas supply path (not shown) is connected to the left burner 16a. The gas supply path is provided with a flow rate adjustment valve (not shown) for adjusting the amount of gas supplied to the left burner 16a. The left burner 16a is ignited by operating an igniter (not shown) while gas is being supplied to the left burner 16a. The amount of heat generated by the left burner 16a can be adjusted by adjusting the amount of gas supplied to the left burner 16a. When the gas supply to the left burner 16a is stopped, the left burner 16a is extinguished. The right burner 16b and the rear burner 16c have the same structure as the left burner 16a.

[0028] The cooking appliance 10 further includes a grill chamber 20 and a grill door 22. The grill chamber 20 is provided inside the main body 12 and accommodates an object to be heated. The grill door 22 is disposed on the front side of the main body 12 and opens and closes the grill chamber 20. A grill burner 24 (see FIG. 2) is provided inside the grill chamber 20 to heat the object to be heated accommodated in the grill chamber 20.

[0029] Cooking appliance 10 further includes a stove operation unit 28, a stove display unit 30, a grill operation unit 32, a grill display unit 34, and a power switch 36. ...

[0030] The stove operation unit 28 includes three heating amount operation units 38a, 38b, and 38c and three panel operation units 40a, 40b, and 40c. The heating amount operation units 38a, 38b, and 38c are operation units for igniting and extinguishing the corresponding stove burners 16a, 16b, and 16c and adjusting the heating amount of the corresponding stove burners 16a, 16b, and 16c. The panel operation units 40a, 40b, and 40c are operation units for setting automatic cooking on the corresponding stove burners 16a, 16b, and 16c. The stove display unit 30 displays the operating status of each stove burner 16a, 16b, and 16c, information related to automatic cooking, and the like.

[0031] The grill operation unit 32 includes a heat amount operation unit 42 and a panel operation unit 44. The heat amount operation unit 42 is an operation unit for turning on and off the grill burner 24 and adjusting the heat amount of the grill burner 24. The panel operation unit 44 is an operation unit for setting automatic cooking on the grill burner 24. The grill display unit 34 displays the operating status of the grill burner 24, information related to automatic cooking, and the like.

[0032] In the following description, the stove burner 16 may be simply referred to as the "stove 16," and the grill burner 24 may be simply referred to as the "grill 24." The stove burner 16 and the grill burner 24 may be collectively referred to as the "heating unit 17" (see FIG. 2).

[0033] The cooking appliance 10 further includes a microphone 60 and a speaker 62. The microphone 60 and the speaker 62 are provided on the front surface of the main body 12. The microphone 60 acquires sounds uttered by the user (for example, a heating unit-specific sound, a cooking mode-specific sound, and a setting value-specific sound, which will be described later). The speaker 62 outputs a predetermined sound (for example, a request sound, which will be described later) to the user.

[0034] 2, the cooking appliance 10 further includes a control unit 48 and a storage unit 50. The control unit 48 includes a CPU, a ROM, a RAM, etc., and controls the operation of each component of the cooking appliance 10. The storage unit 50 includes an EEPROM, a flash memory, etc., and stores various data used by the control unit 48 when executing processing.

[0035] (Relationship between the heating unit 17, cooking mode, and setting value; Figure 3) Next, the relationship between the heating units 17, cooking modes, and setting values ​​will be described. As shown in Fig. 3, each of the multiple heating units 17 (left burner 16a, right burner 16b, rear burner 16c, and grill 24) can execute one or more cooking modes. For example, the left burner 16a and right burner 16b can execute cooking modes such as timer and temperature setting. The rear burner 16c can execute cooking modes such as timer and rice. The grill 24 can execute cooking modes such as toast and steamed vegetables.

[0036] Furthermore, one or more setting values ​​can be set for each of one or more cooking modes in each heating unit 17. Setting values ​​include, for example, time, temperature, amount, intensity, type, etc. For example, the timer cooking mode can be set to a setting value of 1 minute, 3 minutes, etc. The temperature setting cooking mode can be set to a setting value of 130°C, 140°C, etc. The rice cooking mode can be set to a setting value of 1 cup, 2 cups, etc. The toast cooking mode can be set to a setting value of, for example, standard, strong, weak, etc. The steamed vegetable cooking mode can be set to settings for root vegetables, leafy vegetables, etc.

[0037] The one or more cooking modes executable by the heating unit 17 include cooking modes that can be executed "only" by a specific heating unit 17. For example, the cooking mode for steamed vegetables can be executed "only" by the grill 24. Furthermore, the one or more setting values ​​that can be set in a cooking mode include setting values ​​that can be set "only" in a specific cooking mode. For example, setting values ​​for root vegetables, leafy vegetables, etc. can be set "only" in the cooking mode for steamed vegetables.

[0038] (Explanation of the registered voice; Figure 4) Next, the registered sounds will be described. As shown in Fig. 4, the storage unit 50 pre-stores a plurality of registered sounds. The plurality of registered sounds includes a plurality of heating unit-specific sounds, a plurality of cooking mode-specific sounds, and a plurality of setting value-specific sounds.

[0039] The heating unit specifying sound is a sound that specifies one of the heating units 17 in the cooker 10, such as "left burner" or "grill." The cooking mode specifying sound is a sound that specifies one of the cooking modes in the cooker 10, such as "timer" or "steamed vegetables." The setting value specifying sound is a sound that specifies one of the setting values ​​in the cooker 10, such as "1 minute" or "root vegetables."

[0040] The storage unit 50 stores a plurality of registered sounds (heating unit specific sounds, cooking mode specific sounds, and setting value specific sounds) after categorizing them. In the following description, the heating unit specific sounds may be categorized as type 1, the cooking mode specific sounds as type 2, and the setting value specific sounds as type 3.

[0041] (Audio acquisition process; Figure 5) Next, a voice acquisition process for acquiring voice uttered by the user will be described. The voice acquisition process of the embodiment starts, for example, when the power of the cooking appliance 10 is turned on. As shown in FIG. 5, in S2 of the voice acquisition process, the control unit 48 determines whether the current state of the cooking appliance 10 is in a voice standby state. The cooking appliance 10 switches from the normal state to the voice standby state, for example, when the power is switched from off to on. In a modified example, the cooking appliance 10 may be configured to switch from the normal state to the voice standby state when the microphone 60 acquires a predetermined wake-up voice. Furthermore, the cooking appliance 10 may be configured to switch from the normal state to the voice standby state when an ignition operation is performed on any of the burners 16a, 16b, 16c, and 24 in any of the heat amount operation units 38a, 38b, 38c, and 42. When the cooking appliance 10 is in the voice standby state, the microphone 60 of the cooking appliance 10 can acquire voices uttered by the user to identify the heating unit 17, cooking mode, and setting values. If the cooking appliance 10 is in the voice standby state (YES in S2), the process proceeds to S4. If the cooking appliance 10 is not in the voice standby state (NO in S2), the process of S2 is repeated.

[0042] When the cooker 10 is in a voice standby state, the user of the cooker 10 makes a sound to identify the heating unit 17, cooking mode, and setting value. That is, the user makes a heating unit-specific sound, a cooking mode-specific sound, and a setting value-specific sound. For example, the user makes a sound such as "left burner, timer, 1 minute." At this time, the user may make a sound such as "left burner, timer, 1 minute," in any order. For example, the user may make a sound such as "left burner, timer, 1 minute, left burner."

[0043] Furthermore, the user does not have to utter all of the heating unit specific sound, cooking mode specific sound, and setting value specific sound, and may utter only two of these sounds. For example, the user may utter "left burner, timer." In this case, the user may utter two of the heating unit specific sound, cooking mode specific sound, and setting value specific sound in any order. For example, the user may utter "timer, left burner."

[0044] Alternatively, the user may utter only one of the heating unit specific sound, cooking mode specific sound, and setting value specific sound. For example, the user may utter "left burner." The user may utter at least one of the heating unit specific sound, cooking mode specific sound, and setting value specific sound.

[0045] Furthermore, when uttering at least one of the heating unit-specific sound, cooking mode-specific sound, and setting value-specific sound, the user may utter a different sound unrelated to these sounds. For example, the user may utter a different sound unrelated to these sounds before, after, or between these sounds. For example, the user may utter "AA, left burner, BB, timer, CC, 1 minute."

[0046] The voice uttered by the user is picked up by the microphone 60 of the cooking appliance 10. The microphone 60 picks up the voice in the order in which the user utters the voice. For example, if the user utters "AA, left burner, BB, timer, CC, 1 minute," the microphone 60 picks up the voice in the order "AA," "left burner," "BB," "timer," "CC," and "1 minute."

[0047] In S4 of the voice acquisition process (see FIG. 5), the control unit 48 determines whether or not the microphone 60 has acquired a voice uttered by the user (for example, "AA"). If the microphone 60 has acquired a voice uttered by the user (YES in S4), the process proceeds to S6. If the microphone 60 has not acquired a voice (NO in S4), the process proceeds to S10.

[0048] In S6, the control unit 48 determines whether the voice (e.g., "AA") acquired by the microphone 60 in S4 matches any one of the multiple registered voices (see FIG. 4) stored in the storage unit 50. If the voices match (YES in S6), the process proceeds to S8, and if they do not match (NO in S6), the process returns to S4. In a modified example, the voice acquisition process may end if NO in S6.

[0049] In S4 after NO in S6, the control unit 48 again determines whether the microphone 60 has acquired the voice uttered by the user. With respect to the voice uttered by the user (e.g., "AA, left burner, BB, timer, CC, 1 minute"), the control unit 48 determines whether the microphone 60 has acquired the voice (e.g., "left burner") that follows the voice (e.g., "AA") processed in the previous step of S4. The microphone 60 acquires the voices in the order in which the user utters the voices, and the control unit 48 processes the voices in the order in which the microphone 60 acquires them. If YES in S4, the process proceeds to S6, and if NO in S4, the process proceeds to S10.

[0050] In S10 after NO in S4, the control unit 48 determines whether a predetermined waiting time (for example, 10 seconds) has elapsed since determining YES in S2 (or since determining NO in S6). If the predetermined waiting time has not elapsed (NO in S10), the process returns to S4. On the other hand, if the predetermined waiting time has elapsed (YES in S10), the voice acquisition process ends. In this case, the voice acquisition process ends without the first voice being determined. Furthermore, the voice acquisition process ends without the second voice and the third voice, which will be described later, being determined.

[0051] In S8 after YES in S6 above, the control unit 48 determines the voice that matches the registered voice in S6 (for example, "left burner") as the first voice. The control unit 48 stores the determined first voice in the storage unit 50.

[0052] In S12 after S8, the control unit 48 again determines whether the microphone 60 has acquired a voice uttered by the user. With respect to a voice uttered by the user (e.g., "AA, left burner, BB, timer, CC, 1 minute"), the control unit 48 determines whether the microphone 60 has acquired the voice (e.g., "BB") following the voice (e.g., "left burner") processed in the previous step of S4. The microphone 60 acquires the voices in the order in which the user utters the voices, and the control unit 48 processes the voices in the order in which the microphone 60 acquires them. If YES in S12, the process proceeds to S14, and if NO in S12, the process proceeds to S18.

[0053] In S14, the control unit 48 determines whether the voice (e.g., "BB") acquired by the microphone 60 in S12 matches any one of the multiple registered voices (see FIG. 4) stored in the storage unit 50. In S14, the control unit 48 makes the determination based on the multiple registered voices stored in the storage unit 50 that belong to a different class (e.g., class 2 and class 3) from the class (e.g., class 1) to which the first voice (e.g., "left burner") determined in S8 above belongs. The control unit 48 determines whether the voice acquired by the microphone 60 matches any one of the multiple registered voices that belong to a different class from the class to which the first voice determined in S8 belongs. If the voices match (YES in S14), the process proceeds to S16. If they do not match (NO in S14), the process returns to S12. In a modified example, the voice acquisition process may end if the result in S14 is NO.

[0054] In S12 after NO in S14, the control unit 48 again determines whether the microphone 60 has acquired a voice uttered by the user. With respect to a voice uttered by the user (for example, "AA, left burner, BB, timer, CC, 1 minute"), the control unit 48 determines whether the microphone 60 has acquired the voice (for example, "timer") following the voice (for example, "BB") processed in the previous step of S12. The microphone 60 acquires the voices in the order in which the user utters the voices, and the control unit 48 processes the voices in the order in which the microphone 60 acquires them. If YES in S12, the process proceeds to S14, and if NO in S12, the process proceeds to S18.

[0055] In S18 after NO in S12, the control unit 48 determines whether a predetermined waiting time (for example, 10 seconds) has elapsed since determining YES in S6 above (or since determining NO in S14). If the predetermined waiting time has not elapsed (NO in S18), the process returns to S12. On the other hand, if the predetermined waiting time has elapsed (YES in S18), the voice acquisition process ends. In this case, the voice acquisition process ends without the second voice being determined. Furthermore, the voice acquisition process ends without the third voice, which will be described later, being determined. Note that the first voice is determined in S8 above.

[0056] In S16 after YES in S14 above, the control unit 48 determines the voice (e.g., "timer") that matches the registered voice in S14 as the second voice. The control unit 48 stores the determined second voice in the storage unit 50.

[0057] In S20 after S16, the control unit 48 again determines whether the microphone 60 has acquired a voice uttered by the user. With respect to a voice uttered by the user (for example, "AA, left burner, BB, timer, CC, 1 minute"), the control unit 48 determines whether the microphone 60 has acquired the voice (for example, "CC") that follows the voice (for example, "timer") processed in the previous step of S12. The microphone 60 acquires the voices in the order in which the user utters the voices, and the control unit 48 processes the voices in the order in which the microphone 60 acquires them. If the answer is YES in S20, the process proceeds to S22, and if the answer is NO in S20, the process proceeds to S26.

[0058] In S22, the control unit 48 determines whether the voice (e.g., "CC") acquired by the microphone 60 in S20 matches any one of the multiple registered voices (see FIG. 4) stored in the storage unit 50. In S22, the control unit 48 makes a determination based on the multiple registered voices stored in the storage unit 50 that belong to a different class (e.g., class 3) from the classes (e.g., class 1 and class 2) to which the first voice (e.g., "left burner") determined in S8 and the second voice (e.g., "timer") determined in S16 belong. The control unit 48 determines whether the voice acquired by the microphone 60 matches any one of the multiple registered voices that belong to a class (e.g., class 3) different from the classes to which the first voice determined in S8 and the second voice determined in S16 belong. If the voices match (YES in S22), the process proceeds to S24. If they do not match (NO in S22), the process returns to S20. In a modified example, if the answer is NO in S22, the voice acquisition process may end.

[0059] In S20 after NO in S22, the control unit 48 again determines whether the microphone 60 has acquired a voice uttered by the user. With respect to a voice uttered by the user (for example, "AA, left burner, BB, timer, CC, 1 minute"), the control unit 48 determines whether the microphone 60 has acquired the voice (for example, "1 minute") following the voice (for example, "CC") processed in the previous step of S20. The microphone 60 acquires the voices in the order in which the user utters the voices, and the control unit 48 processes the voices in the order in which the microphone 60 acquires them. If YES in S20, the process proceeds to S22, and if NO in S20, the process proceeds to S26.

[0060] In S26 after NO in S20, the control unit 48 determines whether a predetermined waiting time (e.g., 10 seconds) has elapsed since determining YES in S14 above (or since determining NO in S22). If the predetermined waiting time has not elapsed (NO in S26), the process returns to S20. On the other hand, if the predetermined waiting time has elapsed (YES in S26), the voice acquisition process ends. In this case, the voice acquisition process ends without the third voice being determined. Note that the first voice is determined in S8 above, and the second voice is determined in S16 above.

[0061] In S24 after YES in S22 above, the control unit 48 determines the voice (e.g., "1 minute") that matches the registered voice in S22 as the third voice. The control unit 48 stores the determined third voice in the storage unit 50. After the third voice is determined, the voice acquisition process ends.

[0062] In the above-described voice acquisition process, if the microphone 60 acquires all of the heating unit-specific voice, cooking mode-specific voice, and setting value-specific voice, the first voice, the second voice, and the third voice are determined. In this case, the first identification process (see FIGS. 6 and 7) described later is executed.

[0063] On the other hand, if the microphone 60 acquires any two of the heating unit-specific sound, cooking mode-specific sound, and setting value-specific sound during the sound acquisition process, but does not acquire the remaining sound, the first and second sounds are determined, but the third sound is not determined. In this case, the second determination process (see FIGS. 8 and 9) described below is executed.

[0064] Furthermore, if the microphone 60 acquires one of the heating unit-specific sound, cooking mode-specific sound, and setting value-specific sound during the sound acquisition process but does not acquire the remaining two sounds, the first sound is determined, and the second and third sounds are not determined. In this case, the third determination process (see FIG. 11) described below is executed.

[0065] The control unit 48 can identify one of the multiple heating units 17 based on the heating unit-specific sound, cooking mode-specific sound, and set value-specific sound acquired by the microphone 60, and can also identify the cooking mode and set value for the heating operation at the identified heating unit 17. Furthermore, even if the microphone 60 does not acquire at least one of the heating unit-specific sound, cooking mode-specific sound, and set value-specific sound, the control unit 48 can identify one of the multiple heating units 17 based on at least one of the heating unit-specific sound, cooking mode-specific sound, and set value-specific sound acquired by the microphone 60, and can also identify the cooking mode and set value for the heating operation at the identified heating unit 17.

[0066] The following describes the heating unit 17 that performs the heating operation, and the process for identifying the cooking mode and set values ​​for the heating operation.

[0067] (First identification process; Figures 6 and 7) The first identification process of the embodiment will be described. The first identification process is executed when the microphone 60 acquires all of the heating unit specific sound, cooking mode specific sound, and setting value specific sound in the above-mentioned sound acquisition process (see FIG. 5). The first identification process is started, for example, when the sound acquisition process ends.

[0068] 6 and 7, in S30 of the first identification process, the control unit 48 determines whether the first voice confirmed in S8 of the voice acquisition process is a heating unit-specific voice. If the first voice is a heating unit-specific voice, the control unit 48 identifies the heating unit 17 (e.g., the left burner 16a) identified by the heating unit-specific voice (first voice) among the multiple heating units 17 of the cooking appliance 10 as the heating unit 17 that will perform the heating operation. If YES in S30, the process proceeds to S32, and if NO in S30, the process proceeds to S40.

[0069] In S32 after YES in S30, the control unit 48 determines whether the second voice confirmed in S16 of the voice acquisition process is a cooking mode-specific voice that identifies a cooking mode (e.g., a timer) that can be executed by the heating unit 17 (e.g., the left burner 16a) identified in S30. If the second voice is a cooking mode-specific voice that identifies a cooking mode that can be executed by the heating unit 17 identified in S30 (YES in S32), the control unit 48 identifies the cooking mode identified by the cooking mode-specific voice (second voice) as the cooking mode for the heating operation. If YES in S32, the process proceeds to S34, and if NO in S32, the process proceeds to S36.

[0070] In S34 after YES in S32, the control unit 48 determines whether the third voice confirmed in S24 of the voice acquisition process is a setting value specifying voice that specifies a setting value (e.g., 1 minute) that can be set in the cooking mode (e.g., timer) identified in S32. If the third voice is a setting value specifying voice that specifies a setting value that can be set in the cooking mode identified in S32 (YES in S34), the control unit 48 specifies the setting value specified by the setting value specifying voice (third voice) as the setting value for the heating operation. If YES in S34, the process proceeds to S39; if NO in S34, the first identification process ends.

[0071] On the other hand, in S36 after NO in S32 above, the control unit 48 determines whether the third voice confirmed in S24 of the voice acquisition process is a cooking mode-specific voice that identifies a cooking mode (e.g., a timer) that can be executed by the heating unit 17 (e.g., the left burner 16a) identified in S30 above. If the third voice is a cooking mode-specific voice that identifies a cooking mode that can be executed by the heating unit 17 identified in S30 (YES in S36), the control unit 48 identifies the cooking mode identified by the cooking mode-specific voice (third voice) as the cooking mode for the heating operation. If YES in S36, the process proceeds to S38; if NO in S36, the first identification process ends.

[0072] In S38 after YES in S36, the control unit 48 determines whether the second voice confirmed in S16 of the voice acquisition process is a setting value specifying voice specifying a setting value (e.g., 1 minute) that can be set in the cooking mode (e.g., timer) identified in S36. If the second voice is a setting value specifying voice specifying a setting value that can be set in the cooking mode identified in S36 (YES in S38), the control unit 48 specifies the setting value specified by the setting value specifying voice (second voice) as the setting value for the heating operation. If YES in S38, the process proceeds to S39, and if NO in S38, the first specification process ends.

[0073] The above steps S30, S32, S34, S36, and S38 determine the heating unit 17 that will perform the heating operation, and the cooking mode and set values ​​for the heating operation (S39). After identifying the heating unit 17, cooking mode, and set values, the control unit 48 causes the identified heating unit 17 to perform the heating operation identified by the identified cooking mode and set values.

[0074] Next, the process after NO in S30 above will be described. If the process after NO in S30 is the same as the process described above, a detailed description of it may be omitted.

[0075] In S40 after NO in S30, the control unit 48 executes the same process as S30 for the second voice determined in S16 of the voice acquisition process. If YES in S40, the process proceeds to S42, and if NO in S40, the process proceeds to S50.

[0076] In S42, the control unit 48 executes the same process as S32 described above for the first voice determined in S8 of the voice acquisition process. If YES in S42, the process proceeds to S44, and if NO in S42, the process proceeds to S46.

[0077] In S44 after YES in S42, the control unit 48 executes the same process as S34 described above for the third voice determined in S24 of the voice acquisition process. If YES in S44, the process proceeds to S39, and if NO in S44, the first identification process ends.

[0078] In S46 after NO in S42, the control unit 48 executes the same process as S36 described above for the third voice determined in S24 of the voice acquisition process. If YES in S46, the process proceeds to S48, and if NO in S46, the first identification process ends.

[0079] In S48 after YES in S46, the control unit 48 executes the same process as S38 described above for the first voice determined in S8 of the voice acquisition process. If YES in S48, the process proceeds to S39, and if NO in S48, the first identification process ends.

[0080] The heating unit 17 that will perform the heating operation, and the cooking mode and set values ​​for the heating operation are determined by the processes of S40, S42, S44, S46, and S48 (S39). After identifying the heating unit 17, cooking mode, and set values, the control unit 48 causes the identified heating unit 17 to perform the heating operation identified by the identified cooking mode and set values.

[0081] Next, the process after NO in S40 above will be described. If NO in S40, the third voice determined in S24 of the voice acquisition process is a heating unit-specific voice (S50). The control unit 48 identifies the heating unit 17 (e.g., left burner 16a) identified by the heating unit-specific voice (third voice) among the multiple heating units 17 of the cooking appliance 10 as the heating unit 17 that will perform the heating operation.

[0082] In the next S52, the control unit 48 executes the same process as S32 described above for the first voice determined in S8 of the voice acquisition process. If YES in S52, the process proceeds to S54, and if NO in S52, the process proceeds to S56.

[0083] In S54 after YES in S52, the control unit 48 executes the same process as S34 described above for the second voice determined in S16 of the voice acquisition process. If YES in S54, the process proceeds to S39, and if NO in S54, the first identification process ends.

[0084] In S56 after NO in S52, the control unit 48 executes the same process as S36 described above for the second voice determined in S16 of the voice acquisition process. If YES in S56, the process proceeds to S58, and if NO in S56, the first identification process ends.

[0085] In S58 after YES in S56, the control unit 48 executes the same process as S38 described above for the first voice determined in S8 of the voice acquisition process. If YES in S58, the process proceeds to S39, and if NO in S58, the first identification process ends.

[0086] The heating unit 17 that will perform the heating operation, and the cooking mode and set values ​​for the heating operation are determined by the processes of S50, S52, S54, S56, and S58 (S39). After identifying the heating unit 17, cooking mode, and set values, the control unit 48 causes the identified heating unit 17 to perform the heating operation identified by the identified cooking mode and set values.

[0087] (Second identification process: Figures 8 and 9) Next, the second identification process of the embodiment will be described. The second identification process is executed when the microphone 60 acquires any two of the heating unit specific sound, cooking mode specific sound, and setting value specific sound in the above-mentioned sound acquisition process (see FIG. 5), but does not acquire the remaining sound. The second identification process is started, for example, when the sound acquisition process ends.

[0088] 8 and 9, in S60 of the second identification process, the control unit 48 determines whether the first voice confirmed in S8 of the voice acquisition process is a heating unit-specific voice. If the first voice is a heating unit-specific voice (YES in S60), the control unit 48 identifies the heating unit 17 (e.g., left burner 16a) identified by the heating unit-specific voice (first voice) among the multiple heating units 17 of the cooking appliance 10 as the heating unit 17 that will perform the heating operation. If YES in S60, the process proceeds to S62, and if NO in S60, the process proceeds to S70.

[0089] In S62 after YES in S60, the control unit 48 determines whether the second voice confirmed in S16 of the voice acquisition process is a cooking mode-specific voice that identifies a cooking mode (e.g., a timer) that can be executed by the heating unit 17 (e.g., the left burner 16a) identified in S60. If the second voice is a cooking mode-specific voice that identifies a cooking mode that can be executed by the heating unit 17 identified in S60 (YES in S62), the control unit 48 identifies the cooking mode identified by the cooking mode-specific voice (second voice) as the cooking mode for the heating operation. If YES in S62, the process proceeds to S64, and if NO in S62, the process proceeds to S66.

[0090] The second identification process is executed when the third voice is not confirmed in the voice acquisition process (see FIG. 5). Therefore, the control unit 48 cannot identify the setting values ​​for the heating operation based on the third voice. Therefore, in S64 after YES in S62, the control unit 48 sets the setting values ​​for the current heating operation to the same setting values ​​as the setting values ​​for the previous (most recent) heating operation of heating operations previously performed in the same cooking mode as the cooking mode identified in S62. The setting values ​​for the previously performed heating operations are stored in the memory unit 50.

[0091] In a modified example, in S64, the control unit 48 may set the setting value for the current heating operation to the setting value that is set as the initial value (for example, the setting value at the time of shipment from the factory) in the cooking mode identified in S62.

[0092] On the other hand, in S66 after NO in S62 above, the control unit 48 determines whether the second voice confirmed in S16 of the voice acquisition process is a setting value specifying voice that specifies a setting value that can be set "only" in the "specific" cooking mode among the cooking modes that can be executed by the heating unit 17 identified in S60 above. If the second voice is a setting value specifying voice that specifies a setting value that can be set "only" in the "specific" cooking mode among the cooking modes that can be executed by the heating unit 17 identified in S60 (YES in S66), the control unit 48 specifies the setting value specified by the setting value specifying voice (second voice) as the setting value for the heating operation, and specifies the "specific" cooking mode in which the setting value can be set as the cooking mode for the heating operation.

[0093] For example, if the heating unit 17 identified in S60 is the grill 24 and the second voice is a setting value identification voice that identifies a setting value (e.g., root vegetables) that can be set "only" in a "specific" cooking mode (e.g., steamed vegetables) among the cooking modes executable on the grill 24, the control unit 48 identifies the setting value (e.g., root vegetables) identified by the setting value identification voice (second voice) as the setting value for the heating operation. The control unit 48 also identifies the "specific" cooking mode (e.g., steamed vegetables) among the cooking modes in which the setting value (e.g., root vegetables) can be set as the cooking mode for the heating operation. If YES in S66, the process proceeds to S69, and if NO in S66, the second identification process ends.

[0094] If NO in S60 above, in S70, the control unit 48 determines whether the first voice confirmed in S8 of the voice acquisition process is a cooking mode-specific voice that identifies a cooking mode (e.g., steamed vegetables) that can be performed "only" by the "specific" heating unit 17 (e.g., the grill 24). If the first voice is a cooking mode-specific voice that identifies a cooking mode that can be performed "only" by the "specific" heating unit 17 (YES in S70), the control unit 48 identifies the cooking mode identified by the cooking mode-specific voice (first voice) as the cooking mode for the heating operation, and identifies the "specific" heating unit 17 that can perform that cooking mode as the heating unit 17 that will perform the heating operation. If YES in S70, the process proceeds to S72; if NO in S70, the process proceeds to S74.

[0095] In S72 after YES in S70, the control unit 48 determines whether the second voice confirmed in S16 of the voice acquisition process is a setting value specifying voice that specifies a setting value (e.g., root vegetables) that can be set in the cooking mode (e.g., steamed vegetables) specified in S70. If the second voice is a setting value specifying voice that specifies a setting value that can be set in the cooking mode specified in S70 (YES in S72), the control unit 48 specifies the setting value specified by the setting value specifying voice (second voice) as the setting value for the heating operation. If YES in S72, the process proceeds to S69; if NO in S72, the second specification process ends.

[0096] In S74 after NO in S70 above, the control unit 48 determines whether the first voice confirmed in S8 of the voice acquisition process is a cooking mode-specific voice that identifies a cooking mode (e.g., a timer). If the first voice is a cooking mode-specific voice (YES in S74), the control unit 48 identifies the cooking mode identified by the cooking mode-specific voice (first voice) as the cooking mode for the heating operation. If YES in S74, the process proceeds to S76, and if NO in S74, the process proceeds to S82.

[0097] In S76 after YES in S74, the control unit 48 determines whether the second voice confirmed in S16 of the voice acquisition process is a heating unit-specific voice that identifies a heating unit 17 (e.g., left burner 16a) that can execute the cooking mode (e.g., timer) identified in S74 above. If the second voice is a heating unit-specific voice that identifies a heating unit 17 that can execute the cooking mode identified in S74 (YES in S76), the control unit 48 identifies the heating unit 17 identified by the heating unit-specific voice (second voice) as the heating unit 17 that will perform the heating operation. If YES in S76, the process proceeds to S78, and if NO in S76, the process proceeds to S80.

[0098] The second identification process is executed when the third voice is not confirmed in the voice acquisition process (see FIG. 5). Therefore, the control unit 48 cannot identify the setting values ​​for the heating operation based on the third voice. Therefore, in S78 after YES in S76, the control unit 48 sets the setting values ​​for the current heating operation to the same setting values ​​as the setting values ​​for the previous (most recent) heating operation of heating operations previously performed in the same cooking mode as the cooking mode identified in S74. The setting values ​​for the previously performed heating operations are stored in the memory unit 50.

[0099] In the second identification process, the heating unit 17 that performs the heating operation, and the cooking mode and set values ​​for the heating operation are determined by the processes of S60, S62, S64, S66, S70, S72, S74, S76, and S78 (S69).

[0100] On the other hand, in S80 after NO in S76 above, the control unit 48 determines whether the second voice confirmed in S16 of the voice acquisition process is a setting value specifying voice that specifies a setting value (e.g., 1 minute) that can be set in the cooking mode (e.g., timer) specified in S74 above. If the second voice is a setting value specifying voice that specifies a setting value that can be set in the cooking mode specified in S74 (YES in S80), the control unit 48 specifies the setting value specified by the setting value specifying voice (second voice) as the setting value for the heating operation. If YES in S80, the process proceeds to S89, and if NO in S80, the second specification process ends.

[0101] If the answer is NO in S74 above, the first sound confirmed in S8 of the sound acquisition process is a setting value specifying sound (S82). The control unit 48 specifies the setting value (for example, 1 minute) specified by the setting value specifying sound (first sound) as the setting value for the heating operation.

[0102] In the next S84, the control unit 48 determines whether the second voice confirmed in S16 of the voice acquisition process is a cooking mode-specific voice that identifies a cooking mode (e.g., a timer) in which the setting value identified in S82 (e.g., 1 minute) can be set. If the second voice is a cooking mode-specific voice that identifies a cooking mode in which the setting value identified in S82 can be set (YES in S84), the control unit 48 identifies the cooking mode identified by the cooking mode-specific voice (second voice) as the cooking mode for the heating operation. If YES in S84, the process proceeds to S89, and if NO in S84, the process proceeds to S86.

[0103] In S86 after NO in S84, the control unit 48 determines whether the setting value identified in S82 above is a setting value (e.g., root vegetables) that can be set "only" in a "specific" cooking mode (e.g., steamed vegetables). In addition, in S86, the control unit 48 determines whether the second voice confirmed in S16 of the voice acquisition process is a heating unit-specific voice that identifies a heating unit 17 (e.g., grill 24) that can execute a "specific" cooking mode (e.g., steamed vegetables) to which the setting value identified in S82 above can be set. If YES in S86, the control unit 48 identifies the "specific" cooking mode as the cooking mode for the heating operation, and identifies the heating unit 17 identified by the heating unit-specific voice (second voice) (the heating unit 17 that can execute the "specific" cooking mode) as the heating unit 17 that will execute the heating operation. If YES in S86, the process proceeds to S69. If NO in S86, the second identification process ends.

[0104] In the second identification process, the cooking mode and setting values ​​for the heating operation are determined by the processes of S74, S80, S82, and S84 (S89). However, these processes do not determine the heating unit 17 that will perform the heating operation. In S90 after S89, the control unit 48 executes a heating unit identification process to identify the heating unit 17 that will perform the heating operation.

[0105] (Heated part identification process; Figure 10) The heating unit specifying process of the embodiment will be described. As shown in Fig. 10, when the heating unit specifying process is started, in S92, the control unit 48 outputs a request voice from the speaker 62, which is a voice requesting the user to utter a heating unit specifying voice for specifying a heating unit 17. The speaker 62 outputs the request voice, for example, "Please specify a heating unit." When the speaker 62 outputs the request voice, the cooking appliance 10 enters a voice standby state. At this time, all heating units 17 capable of executing the cooking modes specified in S74 and S84 above may be configured to be set to a standby state.

[0106] In the next step S94, the control unit 48 determines whether the microphone 60 has picked up the user's voice (for example, "left burner"). If the microphone 60 has picked up the user's voice (YES in S94), the process proceeds to S96. If the microphone 60 has not picked up the user's voice (NO in S94), the process proceeds to S98.

[0107] In S96, the control unit 48 determines whether the sound acquired by the microphone 60 in S94 is a heating unit-specific sound that identifies a heating unit 17 (e.g., the left burner 16a) that can execute the cooking mode (e.g., a timer) identified in S74 or S84 of the second identification process (see FIGS. 8 and 9). If the acquired sound is a heating unit-specific sound that identifies a heating unit 17 that can execute the cooking mode identified in S74 or S84 (YES in S96), the control unit 48 identifies the heating unit 17 identified by the heating unit-specific sound (acquired sound) as the heating unit 17 that will perform the heating operation. If the answer is YES in S96, the process proceeds to S102, and if the answer is NO in S96, the process returns to S94.

[0108] On the other hand, in S98 after NO in S94 above, the control unit 48 determines whether any one of the plurality of heat amount operation units 38a, 38b, 38c, 42 of the cooking appliance 10 (for example, the heat amount operation unit 38a corresponding to the left burner 16a) has been ignited. If any one of the plurality of heat amount operation units 38a, 38b, 38c, 42 has been ignited (YES in S98), the control unit 48 identifies the heating unit 17 (for example, the left burner 16a) corresponding to that heat amount operation unit (for example, 38a) as the heating unit 17 that will perform the heating operation. If YES in S98, the process proceeds to S102, and if NO in S98, the process proceeds to S100.

[0109] In S100 after NO in S98, the control unit 48 determines whether a predetermined waiting time (e.g., 20 seconds) has elapsed since the speaker 62 output the request sound in S92 (or since NO was determined in S96). If the predetermined waiting time has not elapsed (NO in S100), the process returns to S94. On the other hand, if the predetermined waiting time has elapsed (YES in S100), the heating unit specification process ends. In this case, the heating unit specification process ends with the heating unit 17 not being determined. If YES in S100, the control unit 48 may output an error sound from the speaker 62.

[0110] In the heating unit identification process, the heating unit 17 that will perform the heating operation is determined by the processes of S94, S96, and S98 (S102). At this time, the standby state of the other heating units 17 that have not been identified may be canceled. When the heating unit identification process (S90) ends, the second identification process ends (see FIGS. 8 and 9).

[0111] (Third specific process; Figure 11) Next, a third identification process of the embodiment will be described. The third identification process is executed when the microphone 60 acquires any one of the heating unit specific sound, cooking mode specific sound, and setting value specific sound in the above-mentioned sound acquisition process (see FIG. 5). The third identification process is started, for example, when the sound acquisition process ends.

[0112] As shown in FIG. 11 , in S110 of the third identification process, the control unit 48 determines whether the first voice confirmed in S8 of the voice acquisition process is a setting value identification voice that identifies a setting value (e.g., root vegetables) that can be set “only” in a “specific” cooking mode (e.g., steamed vegetables) among cooking modes that can be “only” executed by the “specific” heating unit 17 (e.g., grill 24). If the first voice is a setting value identification voice that identifies a setting value that can be “only” executed by the “specific” cooking mode among cooking modes that can “only” executed by the “specific” heating unit 17 (YES in S110), the control unit 48 identifies the setting value identified by the setting value identification voice (first voice) as the setting value for the heating operation, identifies the “specific” cooking mode in which the setting value can be set as the cooking mode for the heating operation, and identifies the “specific” heating unit 17 that can execute the cooking mode as the heating unit 17 that will execute the heating operation. If the answer is YES in S110, the process proceeds to S112. If NO in S110, the third identification process ends.

[0113] In the third identification process, the heating unit 17 that performs the heating operation, and the cooking mode and set value for the heating operation are determined by the above process (S112). After identifying the heating unit 17, the cooking mode, and the set value, the control unit 48 causes the identified heating unit 17 to perform the heating operation identified by the identified cooking mode and set value.

[0114] (Correspondence) The microphone 60 is an example of an "audio acquisition unit," the speaker 60 is an example of an "audio output unit," and the heating amount operation units 38a, 38b, 38c, and 42 are examples of an "operation unit."

[0115] (Variation) In a modified example, the heating unit 17 may be identified by a user operation before the microphone 60 acquires the sound. More specifically, before the microphone 60 acquires at least one of the heating unit-identifying sound, the cooking mode-identifying sound, and the setting value-identifying sound, one of the heating amount operation units 38a, 38b, 38c, 42 receives a user operation (e.g., an ignition operation) for identifying the heating unit 17 (e.g., the left burner 16a) that will perform the heating operation. The control unit 48 identifies the heating unit 17 (e.g., the left burner 16a) identified by the user operation received by the heating amount operation unit (e.g., 38a) as the heating unit 17 that will perform the heating operation.

[0116] Then, the microphone 60 acquires at least one of the cooking mode identification sound and the setting value identification sound. The control unit 48 identifies the cooking mode and the setting value for the heating operation based on the at least one of the cooking mode identification sound and the setting value identification sound acquired by the microphone 60.

The technology described in the claims includes various modifications and variations of the specific examples exemplified above. The technical elements described in this specification or drawings exhibit technical utility alone or in various combinations, and are not limited to the combinations described in the claims at the time of filing.
