Description

[Technical field]

[0001] The present invention relates to a cooking appliance such as a stove or grill, and more particularly to a cooking appliance that can be operated by voice. [Background technology]

[0002] 2. Description of the Related Art Among cooking appliances used for cooking food such as meat and fish, there are cooking appliances that are configured to be operable by voice.

[0003] As such a cooking device, Patent Document 1 discloses a sound signal controlled stove in which the operation of a heater is controlled by a sound signal.

[0004] The sound signal controlled stove in Patent Document 1 is a sound signal controlled stove equipped with a heater and a control unit that controls the operation of the heater in response to an external signal, in which a sound signal control unit is attached to the control unit, and the sound signal control unit stores at least one control sound signal corresponding to a specified operation of the heater, and is also provided with a sound signal input section, a sound signal recognition section that recognizes a sound signal input via the sound signal input section, and a sound signal comparison section that compares the recognized sound signal with the stored control sound signal, and is configured so that when the sound signal recognized by the sound signal recognition section matches the stored sound signal through comparison in the sound signal comparison section, the control unit controls the operation of the heater in response to that sound signal.

[0005] The sound signal controlled stove in Patent Document 1 is said to have the advantage that it is not necessary to manually operate the control unit, and the specified operation of the heater can be controlled even when the cook (user) has both hands full or is in a remote location. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] JP 2001-263669 A Summary of the Invention [Problem to be solved by the invention]

[0007] However, in the case of the sound signal controlled stove of Patent Document 1, in order to adjust the heat strength to the intended strength during the cooking process, the user needs to give specific instructions for the heat strength by voice. For example, it may be necessary to repeatedly recite voice instructions such as (1) "Right burner power 9" ⇒ "Right burner power 7" ⇒ "Right burner power 8" or (2) "Turn up the heat" ⇒ "Turn up the heat" ⇒ "Turn down the heat" etc. This is not only cumbersome, but in some cases the heat may be stronger than expected, resulting in cooking failure or the risk of burns.

[0008] The present invention is devised to solve the above-mentioned problems, and aims to provide a heating cooker that allows the user to adjust the heat output by voice operation, is highly convenient, and provides a sense of security regarding voice operation. [Means for solving the problem]

[0009] In order to achieve the above-mentioned object, the heating cooker of the present invention comprises a heating means for heating the food to be cooked, a manual operation means for manually adjusting the heat power of the heating means, and a control means for controlling the heat power of the heating means so that the heat power is the heat power specified by the voice when the heat power of the heating means is specified by voice, wherein the control means is configured to execute an ignition operation of the heating means at a predetermined heat power (ignition heat power) when a user executes an ignition operation by the manual operation means, and is configured to execute heat power control of the heating means in accordance with the voice instruction when the heat power of the heating means is specified by voice, with the predetermined heat power (ignition heat power) as an upper limit.

[0010] In addition, in the heating cooker of the present invention, it is preferable that the maximum heating power is set to the highest heating power among multiple types of heating power that are manually set by the manual operation means and are used continuously for a predetermined period of time or more. Effect of the Invention

[0011] The cooking device of the present invention is configured as described above, and the control means controls the heating power of the heating means according to voice instructions with a predetermined heating power (ignition power) as the upper limit, so that when the heating power is increased by voice operation, the heating power of the heating means does not exceed the heating power that the user expects to use during cooking, providing safety and a sense of security regarding voice operation. As a result, a cooking device that can be voice operated, is highly convenient, and has high reliability in response to voice operation can be provided.

[0012] Furthermore, the cooking device of the present invention is manually set by the manual operation means, and the highest of multiple types of heating power that are used continuously for a predetermined period of time or more becomes the maximum heating power. Therefore, even if the heating power of the heating means is temporarily adjusted to a heating power that is too high during manual operation, such an excessively high heating power will not be set to the maximum heating power, making it possible to provide a cooking device that is more convenient and safer.

[0014] The features of the present invention will be described in more detail below with reference to the embodiments of the present invention. [Embodiment 1] In this embodiment 1, the cooking appliance will be described taking as an example a so-called built-in type gas stove with a grill, which is inserted from above into a stove mounting port formed in a kitchen counter and assembled thereto.

[0015] <Basic configuration of the cooking device (gas stove) according to the first embodiment> As shown in Figs. 12 and 3, the gas stove according to the first embodiment is equipped with three burners (a standard burner 1a, a high-power burner 1b, and a small burner 1c) as heating means for heating the food to be cooked (usually a cooking vessel in which the food to be cooked is accommodated).

[0016] The gas stove according to the first embodiment also includes a grill section 4 on which food to be cooked, such as fish, is placed, and a grill burner 2 (see FIG. 2) is disposed within the grill section 4.

[0017] The standard burner 1 (1a) is also provided with a temperature sensor (pot bottom temperature sensor) 9 for contacting the cooking vessel to detect its temperature. It is also possible to provide similar temperature sensors on the high heat burner 1b and the small burner 1c.

[0018] On the front side of the gas stove, there are arranged the above-mentioned stove burner 1, burner operation units 21 (standard burner operation unit 21a, high-power burner operation unit 21b, small burner operation unit 21c) for manually igniting and extinguishing the grill burner 2 provided in the grill section 4, and adjusting the flame power, as well as a grill burner operation unit 22 (Figure 1) for manually igniting and extinguishing the grill burner 2, and adjusting the flame power, etc.

[0019] The above-mentioned burner operation unit 21 (standard burner operation unit 21a, high-power burner operation unit 21b, small burner operation unit 21c) is configured to function as a manual operation means for manually adjusting the heat of each stove burner (heating means) 1 in the present invention.

[0020] Also, as shown in FIG. 2, each of the stove burners 1 (standard burner 1a, high-power burner 1b, small burner 1c) is provided with an ignition plug 7 as an ignition device that performs ignition operation and a thermocouple 8 for detecting the ignition state, and each of the grill burners 2 (upper burner 2a, lower burners 2b, 2c) is also provided with an ignition plug 7 as an ignition device that performs ignition operation and a thermocouple 8 for detecting the ignition state.

[0021] The configuration for gas supply to the stove burner 1 and the grill burner 2 is as follows. As shown in FIG. 2, a main gas solenoid valve 12 (which functions as a main gas shut-off valve that is kept open when either the stove burner 1 or the grill burner 2 is used, and kept closed when neither is used) is provided in the main gas supply passage (main gas piping) 11, and the main gas supply passage 11 branches into a branch passage 13a for a standard burner, a branch passage 13b for a high-power burner, a branch passage 13c for a small burner, and a branch passage 13d for a grill burner.

[0022] Each of these branch paths is provided with a flow control valve (gas amount adjustment valve driven by a stepping motor) 3 that adjusts the amount of gas and thereby the amount of heat of each burner, and a position sensor 19 that detects its opening position.

[0023] The front side of the gas stove is provided with a power switch 24 and a power lamp 25 that indicates when the power switch 24 is turned on.

[0024] In addition, five combustion indicator lamps L1, L2, L3, L4, and L5 are arranged near the periphery of the burner operation unit 21 (standard burner operation unit 21a, high-power burner operation unit 21b, and small burner operation unit 21c) as a heat power display means 23 for displaying the amount of heat (see Figure 3). In the gas stove of this embodiment, an LED is used as the combustion indicator lamp (heat amount indicator).

[0025] This gas stove is also configured so that the flame power of the stove burner 1 is adjusted based on commands from the burner operation unit 21 described above.

[0026] In addition, the gas stove (heating cooker) of embodiment 1 is equipped with a control means (operation control means) 50 (Figure 2) that controls the combustion of the stove burner 1, and this control means is configured to execute combustion control that starts the combustion of the stove burner 1 based on a combustion start command and stops the combustion of the stove burner 1 based on a combustion stop command.

[0027] <Characteristic composition> As described above, the gas stove (heating cooker) of embodiment 1 is equipped with a heating means (burner) 1, a manual operation means (burner operation section) 21 (Figures 1, 2, and 3), a flame power display means 23 (Figure 3) consisting of combustion indicator lamps L1, L2, L3, L4, L5, etc., and a control means (operation control means) (Figure 2) 50 that controls the combustion of the burner 1.

[0028] In addition, the gas stove (heating cooker) according to the embodiment of the present invention is configured to be able to display the heat level from heat level 1 (low flame) to heat level 9 (high flame) by turning on, blinking, or turning off the combustion indicator lamps (heat amount display means) L1, L2, L3, L4, and L5 in the manner shown in Figure 4.

[0029] It also includes a sound collecting microphone (FIG. 2) 51 for picking up voice instructions when they are given, a speaker (notification means) 52 (FIG. 2) for notifying the user when a voice instruction on heating power is given, and the like.

[0030] In the gas stove (heating cooker) of embodiment 1, the control means 50 is configured to be able to execute heat control of the heating means (stove burner) 1 in accordance with voice instructions, with the maximum heat among the heat levels manually adjusted by the user using the manual operation means (burner operation unit) 21 as the upper limit. The gas stove (heating cooker) according to the first embodiment is provided with a sound collecting microphone (FIG. 2) 51 for reliably recognizing voice instructions when they are given.

[0031] Furthermore, in the gas stove (heating cooker) of embodiment 1, the heating power is manually set by the manual operation means (burner operation unit) 21, and the highest heating power among multiple types of heating power used continuously for a predetermined period of time or more is configured to be the maximum heating power described above.

[0032] In addition, the control means 50 is configured to execute automatic cooking control that automatically performs heating and cooking using the heating means (cooktop burner) 1, and is configured not to execute heat control in accordance with voice instructions even if voice instructions are given while the automatic cooking control is being executed.

[0033] In addition, the gas stove (heating cooker) of embodiment 1 is equipped with a speaker 52 (Figure 2) which is an informing means for informing that the control means 50 has executed heat power control of the heating means (stove burner) 1 in accordance with voice instructions.

[0034] Furthermore, the gas stove (heating cooker) of embodiment 1 is equipped with multiple heating means (burner) 1, and is configured so that when the voice instruction is for a specific heating means among the multiple heating means (burner) 1, heat control is executed for the specific heating means (burner) 1 so that the heat is the heat instructed by voice, and when the instruction is not for a specific heating means (burner) 1, heat control is executed for all heating means (burner) 1 under heating control so that the heat is the heat instructed by voice.

[0035] Next, with reference to the flowchart in FIG. 5, the operation of the main parts of the gas stove (heat cooker) according to the first embodiment when performing automatic cooking will be described.

[0036] In step S1, when the user operates the manual operation means (burner operation unit) 21 to perform an ignition operation, in step S2, an ignition operation is performed on the heating means (stove burner) 1. Specifically, the flow control valve (gas amount adjustment valve) 3, which also functions as a shutoff valve, opens to a degree that provides a predetermined flame power (ignition flame power), and the igniter turns ON, causing discharge from the ignition plug 7 to ignite the heating means (stove burner) 1.

[0037] Then, in step S3, ignition of the heating means (stove burner) 1 is confirmed. That is, when the electromotive force value V of the thermocouple 8 for detecting ignition is equal to or greater than the electromotive force value Vs for ignition judgment, ignition of the heating means (stove burner) 1 is confirmed.

[0038] If ignition of the heating means (burner) 1 is not confirmed in step S3, the process proceeds to step S11, the flow control valve (gas amount adjustment valve) 3 is closed, the igniter is turned OFF, an error message is displayed in step S12, and cooking ends.

[0039] When the ignition of the heating means (stove burner) 1 is confirmed in step S3, the heating power (ignition heating power) at that time is stored as the maximum heating power (step S4).

[0040] Next, in step S5, it is determined whether or not an automatic cooking instruction has been given. If an automatic cooking instruction has been given, automatic cooking control is executed in step S6.

[0041] Then, in step S7, it is confirmed whether there is a voice instruction (fire instruction) regarding the fire power of the heating means (cooktop burner) 1, and if there is a voice instruction, in step S8, it is notified that the voice instruction is not accepted. This is because if a voice instruction is accepted while automatic cooking control is being executed, it becomes impossible to continue appropriate automatic cooking.

[0042] Next, in step S9, it is determined whether or not an instruction to end the automatic cooking has been given, and if an instruction to end the automatic cooking has been given, the process returns to step S5.

[0043] If there is no voice instruction to increase the heat in step S7 above, the process proceeds to step S9.

[0044] If there is no command to end the automatic cooking in step S9, the process proceeds to step S10, where it is determined whether or not the fire has been turned off, and if there has been no fire-turning operation, the process returns to step S6.

[0045] If an extinguishing operation has been performed in step S10, the process proceeds to step S21, where the extinguishing operation is carried out, thereby ending the cooking.

[0046] Also, if there is no instruction for automatic cooking in step S5, the process proceeds to step S13, where the opening of the flow control valve (gas amount regulating valve) 3 is adjusted so that the heat is adjusted by the manual operation means (burner operation unit) 21, and cooking begins with the heat adjusted by the manual operation means (burner operation unit) 21.

[0047] In step S14, it is determined whether the specified fire power adjusted by the manual operation means (burner operation unit) 21 has continued for 5 seconds or more. If it is determined in step S14 that the specified fire power has continued for 5 seconds or more, the maximum fire power is updated in step S15, and the specified fire power that has continued for 5 seconds or more is stored as the maximum fire power.

[0048] Then, in step S16, it is determined whether or not there is an audio instruction to change the heat level of the heating means (cooktop burner 1), and if there is an audio instruction, in step S17, a notification is made that the audio instruction has been received, and then in step S18, the heat level is adjusted according to the audio instruction, and in step S19, a notification is made that the heat level adjustment has been completed. This notification is made by sound from the notification means (speaker) 52.

[0049] If it is not determined in step S14 that the predetermined heating power has continued for 5 seconds or more, the process proceeds to step S16.

[0050] Thereafter, in step S20, it is determined whether or not a fire-extinguishing operation has been performed, and if a fire-extinguishing operation has been performed, the fire-extinguishing action is executed in step S21, thereby ending the cooking. If a fire-extinguishing operation has not been performed in step S20, the process returns to step S5.

[0051] If there is no voice instruction in step S16, the process proceeds to step S20.

[0052] The cooking device (gas stove) according to the first embodiment is configured as described above, and the control means 50 controls the heat of the heating means (burner) 1 according to voice instructions, with a predetermined heat (ignition heat) as the upper limit, so that when the heat is increased by voice operation, the heat of the heating means (burner) 1 does not exceed the heat expected by the user during cooking, improving the sense of security regarding voice operation. As a result, it is possible to realize a gas stove (cooking device) that can be operated by voice, is highly convenient, and has high reliability in response to voice operation.

[0053] Furthermore, the highest heating power among multiple types of heating power that are manually set by the manual operation means (burner operation unit) 21 and used continuously for a specified period of time or more becomes the maximum heating power. Therefore, even if the heating power of the heating means is temporarily adjusted to a heating power that is too high during manual operation, such an excessively high heating power will not be set to the maximum heating power, making it possible to provide a gas stove (heating cooker) that is more reliable in terms of voice operation.

[0054] In addition, the control means 50 is configured to execute automatic cooking control that automatically performs heating cooking using the heating means (cooker burner) 1, and is configured not to execute heat control in accordance with voice instructions even if voice instructions are given while the automatic cooking control is being executed. Therefore, heat adjustment by voice operation is not performed during automatic cooking, and cooking can be performed reliably using automatic cooking, providing a gas stove (heating cooker) that does not cause cooking errors.

[0055] In addition, the control means 50 is equipped with a speaker (notification means) 52 for notifying that heat control of the heating means (cooktop burner) 1 has been carried out in accordance with voice instructions, so that the user can be sure that the voice operation has been accepted and that heat adjustment has been carried out, making it possible to provide a more convenient heating cooker.

[0056] Next, a method for controlling the heat of the heating means (burner) 1 when using the multiple heating means (burner) 1 provided in the gas stove of this embodiment 1, i.e., the standard burner 1a, the high-power burner 1b, and the small burner 1c, will be described with reference to the flowchart of Figure 6.

[0057] When cooking starts and a voice command to control the heat is given in step S101, it is determined in step S102 whether a specific heating means 1 is specified among the multiple heating means 1, i.e., the standard burner 1a, the high heat burner 1b, and the small burner 1c. There is no restriction on the number of specific heating means 1 that can be specified.

[0058] In step S102, if a specific heating means 1 (either the standard burner 1a, the high-power burner 1b, or the small burner 1c) is specified, in step S103, it is determined whether automatic cooking control is being performed for the specified heating means 1.

[0059] When the automatic cooking control is being executed, in step S104, a notification is given that the heating means 1 for which the automatic cooking control is being executed will not accept a voice instruction on heating power.

[0060] If it is determined in step S103 that automatic cooking control is not being performed for the designated heating means 1, a response notification is made in step S114 to the effect that a heat instruction is accepted, and in step S115, the heat adjustment is performed for the designated heating means 1.

[0061] Thereafter, in step S105, it is determined whether or not a fire-extinguishing operation has been performed. If a fire-extinguishing operation has been performed, the fire-extinguishing action is carried out in step S106, thereby ending the cooking.

[0062] If no fire extinguishing operation has been performed in step S105, the process returns to step S101.

[0063] If there is no voice instruction in step S101, the process proceeds to step S104.

[0064] If a specific heating means 1 (either the standard burner 1a, the high-power burner 1b, or the small burner 1c) is not specified in step S102, it is determined in step S107 whether a heating means 1 that is performing automatic cooking control is included.

[0065] If it is determined in step S107 that the heating means 1 (any of the standard burner 1a, high-power burner 1b, and small burner 1c) that is executing automatic cooking control is included, a notification is issued in step S108 that the heating means 1 (any of the standard burner 1a, high-power burner 1b, and small burner 1c) that is executing automatic cooking control will not accept voice instructions regarding the heating power.

[0066] On the other hand, for the heating means 1 for which automatic cooking control is not being executed (the heating means 1 subject to manual cooking control), a notification is given in step S109 that a voice instruction on heat has been received, and then in step S110, the heat is adjusted in accordance with the voice instruction.

[0067] If in step S107 there is no heating means 1 performing automatic cooking control, in step S112, a voice notification is given for all heating means 1 (standard burner 1a, high-power burner 1b, and small burner 1c) that a power instruction has been received.

[0068] Then, in step S113, the heating power of all the heating means 1 (the standard burner 1a, the high-power burner 1b, and the small burner 1c) is adjusted, and the process proceeds to step S111.

[0069] Then, in step S111, a notice is given that the heating power adjustment has been completed, and the process proceeds to step S105.

[0070] As explained using the flowchart in Figure 6, if the device is equipped with multiple heating means 1 (standard burner 1a, high-power burner 1b, and small burner 1c) and is configured so that if a voice instruction is for a specific heating means among the multiple heating means 1, heat control is performed for that specific heating means, and if the instruction is not for a specific heating means, heat control is performed for all heating means under heating control, it becomes possible to voice-control the heat of the multiple heating means 1 simultaneously as necessary, thereby providing a highly convenient heating cooker.

[0071] Specifically, for example, when it is necessary to temporarily leave the cooking appliance due to a visitor or phone call, it becomes possible to turn off all heating means 1 with a single command or adjust the heat to the specified level, thereby improving convenience. On the other hand, as the heating means performing the automatic cooking control does not accept voice instructions, the automatic cooking control is performed reliably, there is no risk of automatic cooking failure, and the reliability of the automatic cooking control can be ensured.

[0072] [Embodiment 2] Next, a gas stove (heating cooker) according to a second aspect of the present invention (Embodiment 2) will be described.

[0073] The gas stove (heating cooker) according to the second embodiment has a basic configuration similar to that of the gas stove (heating cooker) according to the first embodiment described above with reference to Figs. 1 to 4.

[0074] The following description will focus on the differences from embodiment 1. The reference numerals used to describe each part below are the same as those used in Figs. 1 to 4 to describe the gas stove (heating cooker) according to embodiment 1.

[0075] In the gas stove (heating cooker) of this embodiment 2, the control means 50 is configured to be able to execute (a) a first heat control (the same control as the heat control in the gas stove (heating cooker) of the above-mentioned embodiment 1) that controls the heat of the heating means (burner burner) 1 with the maximum heat manually adjusted by the user using the manual operation means (burner operation unit) 21 as an upper limit, and (b) a second heat control (heat control unique to the gas stove (heating cooker) of the second invention of the present application) that switches the heat of the heating means (burner burner) 1 to a predetermined heat stage among a plurality of heat stages predetermined in a range between a minimum stage and a maximum stage to perform stepped heat control.

[0076] That is, the gas stove (heating cooker) of the second embodiment is configured to perform stepwise firepower control (second firepower control) by switching the firepower of the stove burner (heating means) 1 to a predetermined firepower level among a plurality of firepower levels (9 firepower levels) that are preset within the range of firepower 1 (minimum level) and firepower 9 (maximum level) as shown in Fig. 4. For example, by giving a voice command of "firepower 5," the firepower of the stove burner (heating means) 1 is configured to be adjusted to firepower 5, which is the magnitude of the stepwise firepower.

[0077] When the voice instruction is an instruction to execute the first heat power control, the first heat power control is executed, which sets the heat power of the heating means to the heat power instructed by voice, and when the voice instruction is an instruction to execute the second heat power control, the second heat power control is executed, which sets the heat power of the heating means (cooktop burner) 1 to the heat power level instructed by voice, even if the heat power level instructed by voice exceeds the maximum heat power manually adjusted by the user using the manual operation means.

[0078] Next, with reference to the flow chart of FIG. 7, the operation of the main parts of the gas stove (heat cooker) according to the second embodiment when performing automatic cooking will be described.

[0079] In the flowchart of FIG. 7, steps S201, S202, and S203 provided between steps S17 and S19 are steps specific to the gas stove (heating cooker) according to the second embodiment.

[0080] In addition, since the steps other than step S201, step S202, and step S203 in the flowchart of FIG. 7 are similar to the steps in the case of the gas stove (heating cooker) of embodiment 1 shown in the flowchart of FIG. 5, the explanation thereof will be omitted here.

[0081] In the gas stove (heating cooker) of embodiment 2, if a voice instruction to perform a first heat control is received in step S16 (more specifically, a voice instruction to perform a first heat control in which the heat of the heating means (stove burner) 1 is set to the voice-instructed heat, with the maximum heat adjusted manually by the user using the manual operation means (burner operation unit) 21 as the upper limit), or a voice instruction to perform a second heat control is received (more specifically, a voice instruction to perform a second heat control in which the heat is switched to a predetermined heat step among a plurality of heat steps predetermined in the range between a minimum step and a maximum step, and step-by-step heat control is performed), the process proceeds to step S201.

[0082] In step S201, if the voice instruction is a voice instruction for performing a second heat control (for example, "Set the heat level of the right burner to level 9"), in step S202, the above-mentioned second heat control is executed, in which the heat level of the heating means (burner burner) 1 is set to the heat level instructed by voice.

[0083] Then, in step S202 of executing the second heat control, when executing the second heat control in which the heat of the heating means (burner) 1 is set to the heat level specified by voice, even if the heat level specified by voice exceeds the maximum heat level manually adjusted by the user using the manual operation means, the second heat control is configured to be executed in which the heat of the heating means (burner) 1 is set to the heat level specified by voice.

[0084] When the second heating power control is executed in step S202, a notification is made in step S19 to the effect that the heating power adjustment (second heating power control) of the heating means (stove burner) 1 has been completed. This notification is made by sound from the notification means (speaker) 52.

[0085] Furthermore, if in step S201 the voice instruction is a voice instruction for performing the first heat control (for example, "Turn down the heat of the left burner" or "Maximize the heat of the left burner"), then in step 203 the first heat control (heat control in which the heat of the heating means is set to the heat instructed by voice, with the manually adjusted maximum heat as the upper limit) is executed.

[0086] When the first heat power control is executed in step S203, a notification is made in step S19 to the effect that the heat power adjustment (first heat power control) of the heating means (stove burner) 1 has been completed. This notification is made by sound from the notification means (speaker) 52.

[0087] As described above, the other steps are similar to those in the case of the gas stove (heating cooker) of the first embodiment.

[0088] The gas stove (heating cooker) of embodiment 2 is configured as described above, and when the audio heat instruction is an instruction to execute the second heat control, the control means 50 is capable of increasing the heat of the heating means (stove burner) 1 to a value greater than the maximum heat adjusted by manual operation.

[0089] Therefore, it becomes possible to cook with even greater heat when necessary without being restricted by the maximum heat adjusted by manual operation, making it possible to provide a more convenient heating cooker.
