The imaging range of the camera 92 also includes the surroundings of the stove burners 10a, 10b, and 10c. Further, the camera 92 continuously images the above-mentioned imaging range.

The LED 96a is connected to the front surface 94a of the light guide plate 94, and the LED 96b is connected to the rear surface 94b of the light guide plate 94. Light emitted from the LEDs 96a and 96b enters the light guide plate 94 via the front surface 94a and rear surface 94b of the light guide plate 94. The light incident on the light guide plate 94 is guided to the upper surface 94c of the light guide plate 94, and is emitted from the upper surface 94c. Light emitted from the upper surface 94c of the light guide plate 94 passes through the transmission window 90. As a result, a three-dimensional image 150 is formed in the space above the transmission window 90, for example, as shown in FIG. 4(b). Note that the three-dimensional image displayed in the space above the transmission window 90 is semitransparent.

As shown in FIG. 1, sensors 12a, 12b, 12c are provided corresponding to each stove burner 10a, 10b, 10c. The sensors 12a, 12b, and 12c detect the presence of the object to be heated and the temperature of the object to be heated. The sensors 12a, 12b, 12c can detect an object to be heated (for example, a pot or a frying pan) when it is placed on the stove burner 10a, 10b, 10c. When an object to be heated (pot or frying pan) is placed on the stove burner 10a, 10b, 10c, the sensors 12a, 12b, 12c are pressed by the object to be heated. When pressed by the object to be heated, the sensors 12a, 12b, 12c detect that the object to be heated is placed on the stove burner 10a, 10b, 10c. When no object to be heated is placed on the stove burners 10a, 10b, 10c, the sensors 12a, 12b, 12c are not pressed.

The panel operation section 44 includes a stove display section 46 and stove operation sections 48a, 48b, and 48c. The operating status of each stove burner 10a, 10b, and 10c is displayed on the stove display section 46. The user can set automatic cooking and the like by operating the stove operation section 48a. The stove operation sections 48b and 48c have the same functions as the stove operation section 48a, except that they are operation sections corresponding to the stove burners 10b and 10c, respectively.

The grill operation section 26 includes a heating amount operation section 60 and a panel operation section 62. By operating the heating amount operation unit 60, the user turns on and off the grill burner 20a (see FIG. 3) and adjusts the heating amount (hereinafter sometimes referred to as "firepower") of the grill burner 20a. be able to. The structure of the heating amount operating section 60 is similar to the heating amount operating section 42a of the stove operating section 24.

The panel operation section 62 includes a grill display section 64 and a grill operation section 66. The grill display section 64 displays the operating state of the grill burner 20a and the like. The function of the grill operation section 66 is similar to that of the stove operation section 48a, except that it is an operation section corresponding to the grill burner 20a.

Next, the control configuration of the cooking device 2 will be described with reference to FIG. 3. In addition, in FIG. 3, illustration of the stove burners 10b, 10c, sensors 12b, 12c, heating amount operation parts 42b, 42c, stove operation parts 48b, 48c, and LED 96b is omitted to make the explanation easy to understand. . Further, below, description of the configuration described in FIG. 1 will be omitted.

The heating cooker 2 includes a control section 80. The control unit 80 controls the operation of each component of the cooking device 2. The control unit 80 includes a memory 82. The control unit 80 executes various processes (for example, the setting process in FIG. 6, the detection process in FIG. 7, etc.) according to the program 84 stored in the memory 82. The memory 82 is composed of volatile memory, nonvolatile memory, and the like. The memory 82 also stores reference range information 86 (see FIG. 4), gesture list 88 (see FIG. 5), and a counter value N. The counter value N is information used in the setting process (FIG. 6) described later.

The reference range information 86 is information used in the setting process (FIG. 6) described later. As shown in FIG. 4A, the reference range information 86 includes a gesture detection range 110, a first intrusion detection range 120a, a second intrusion detection range 120b, and a third intrusion detection range 120c. The intrusion detection ranges 120a, 120b, and 120c are ranges for detecting that an object has entered the intrusion detection ranges 120a, 120b, and 120c. The intrusion detection ranges 120a, 120b, and 120c are provided around the stove burners 10a, 10b, and 10c, respectively. The gesture detection range 110 is provided above the top plate 6 between the first intrusion detection range 120a and the second intrusion detection range 120b, and on the near side of the third intrusion detection range 120c. The gesture detection range 110 is a range for extracting user actions (i.e. gestures). The gesture detection range 110 and the intrusion detection ranges 120a, 120b, and 120c are all included in the imaging range of the camera 92. Note that in this embodiment, the gesture execution range in which the user should perform a gesture is configured to match the gesture detection range.

As shown in FIG. 5, the gesture list 88 includes five gestures and a process corresponding to each gesture. Each gesture in FIG. 5 shows a plan view of the user's hand movements.

The gesture of moving the hand back and forth in FIG. 5(a) corresponds to "igniting" the stove burner 10. The stove burner 10 to be lit by the gesture is the stove burner 10 closest to the location where the gesture was made. Hereinafter, the stove burner 10 to which the process corresponding to the gesture is to be performed (that is, the stove burner closest to the position where the gesture was performed) may be referred to as the "target stove burner". The gesture of waving the hand left and right in FIG. 5(b) corresponds to "extinguishing" the target stove burner. The gesture of rotating the hand clockwise in FIG. 5(c) corresponds to "increasing the firepower" of the target stove burner. The gesture of rotating the hand counterclockwise in FIG. 5(d) corresponds to "reducing the firepower" of the target stove burner. The gesture shown in FIG. 5(e) in which the hand is repeatedly held and opened corresponds to "all fire extinguishing". "All extinguishing" means to extinguish all operating stove burners 10a, 10b, and 10c including the target stove burner.

(Setting process; Figure 6)
Next, with reference to FIG. 6, the setting process executed by the control unit 80 of the cooking device 2 will be described. The setting process is a process for setting the gesture detection range and the intrusion detection range according to the operating state of the cooking device 2. When the power switch 40 of the cooking device 2 is operated to turn on the cooking device 2, the control unit 80 starts the process shown in FIG. Note that at the start of the process in FIG. 6, "1" is stored in the counter value N in the memory 82.

In S10, the control unit 80 identifies the N-th stove burner as a specific stove burner based on the counter value N in the memory 82.

In S20, the control unit 80 determines whether the object to be heated is placed on the trivet 8 corresponding to the specific cooking stove burner. If the object to be heated is placed on the trivet 8, the control unit 80 determines YES in S20, and the process proceeds to S22. On the other hand, if the object to be heated is not placed on the trivet 8, the control unit 80 determines NO in S20, and the process proceeds to S30.

In S22, the control unit 80 determines the vicinity of the specific cooking stove burner to be excluded from the gesture detection range 110 (see FIG. 4) based on the size of the heating object placed on the trivet 8 corresponding to the specific cooking stove burner. The first exclusion range is specified. The control unit 80 uses the image captured by the camera 92 to identify the first exclusion range. For example, the control unit 80 specifies the first exclusion range such that the interval between the heating target object and the gesture detection range is a first predetermined interval (for example, 5 cm).

In S24, the control unit 80 determines whether the temperature of the object to be heated detected by the sensor 12 corresponding to the specific cooking stove burner is equal to or higher than a predetermined temperature (for example, 100 [° C.]). If the temperature of the object to be heated is equal to or higher than the predetermined temperature, the control unit 80 determines YES in S24, and the process proceeds to S26. On the other hand, if the temperature of the object to be heated is less than the predetermined temperature, the control unit 80 determines NO in S24, and the process proceeds to S30.

In S26, the control unit 80 specifies a second exclusion range that is a range near the specific stove barna to be excluded from the gesture detection range 110 (see FIG. 4). For example, the control unit 80 specifies the second exclusion range such that the distance between the heating target object and the gesture detection range is a second predetermined distance (for example, 10 cm).

In S30, the control unit 80 determines whether the specific stove burner is in operation. If the specific stove burner is in operation, the control unit 80 determines YES in S30, and the process proceeds to S32. On the other hand, if the specific stove burner is stopped, the control unit 80 determines NO in S30, and proceeds to S40.

In S32, the control unit 80 specifies a third exclusion range, which is a range near the specific cooking stove burner to be excluded from the gesture detection range 110 (see FIG. 4), based on the firepower of the specific cooking stove burner. The control unit 80 sets the size of the third exclusion range based on the firepower of the specific stove burner. In this embodiment, the third exclusion range increases in the order of "large", "medium", and "small" firepower of the specific stove burner.

In S40, the control unit 80 determines whether the counter value N is "3". When the counter value N is "3", the control unit 80 determines YES in S40, and the process proceeds to S50. Note that the case where the counter value N is "3" is the case where the processes of S10 to S32 have been executed for all the stove burners 10a to 10c. On the other hand, if the counter value N is "2" or less, the control unit 80 determines NO in S40, and the process proceeds to S42.

In S42, the control unit 80 increments the counter value N by one. When S42 ends, the process returns to S10.

Further, in S50, the control unit 80 determines whether one or more exclusion ranges have been specified. If one or more exclusion ranges have been specified, the control unit 80 determines YES in S50, and the process proceeds to S52. On the other hand, if the exclusion range has not been specified, the control unit 80 determines NO in S50, and the process proceeds to S56.

In S52, the control unit 80 resets the gesture detection range and the intrusion detection range using the reference range information 86 in the memory 82 and the exclusion ranges specified in S10 to S32. The control unit 80 sets a new gesture detection range by excluding the exclusion range specified in S10 to S32 from the gesture detection range 110 set in the reference range information 86. Further, the control unit 80 adds the exclusion range specified in S10 to S32 to the intrusion detection range set in the reference range information 86 to set a new intrusion detection range. Note that when two or more exclusion ranges corresponding to one stove burner 10 are specified, the control unit 80 uses the largest exclusion range among the two or more exclusion ranges.

In S54, the control unit 80 drives the LEDs 96a and 96b, and uses the gesture detection range and intrusion detection range set in S52 to display a three-dimensional image showing the gesture execution range in the space above the transparent window 90. . For example, as shown in FIG. 8B, the control unit 80 turns on the LEDs 96a and 96b so that the three-dimensional image 152 is formed on the boundary line of the intrusion detection range and the gesture detection range reset in S52. drive.

Further, in S56, the control unit 80 drives the LEDs 96a and 96b, and uses the gesture detection range 110 and the intrusion detection ranges 120a, 120b, and 120c of the reference range information 86 in the memory 82 to detect the space above the transparent window 90. A three-dimensional image 150 showing the gesture execution range is displayed (see FIG. 4(b)).

In S60, the control unit 80 changes the counter value N to "1". When S60 ends, the process returns to S10.

(Detection processing; Figure 7)
Next, with reference to FIG. 7, the detection process executed by the control unit 80 of the cooking device 2 will be described. The detection process is a process for performing a process related to the stove burners 10a, 10b, and 10c based on the user's gesture within the gesture detection range set in the setting process of FIG. In addition, the detection process narrows down the firepower (i.e. reduces the firepower) when an object different from the object to be heated (for example, a human body or clothing) enters the intrusion detection range set in the setting process of FIG. or extinguish a fire). When the power switch 40 of the cooking device 2 is operated and the power of the cooking device 2 is turned on, the control unit 80 starts the process shown in FIG. 7 .

In S70, the control unit 80 monitors whether an object other than the object to be heated enters the intrusion detection range set in the setting process of FIG. If the camera 92 captures an image showing an object such as the user's clothing intruding into the intrusion detection range, the control unit 80 determines YES in S70, and the process proceeds to S72. On the other hand, if an image of an object such as the user's clothing intruding into the intrusion detection range is not captured, the control unit 80 determines NO in S70, and the process proceeds to S90.

In S72, the control unit 80 identifies the stove burner corresponding to the intrusion detection range into which the object has entered. For example, when an object enters the first intrusion detection range, the control unit 80 specifies the first cooking stove burner 10a. Hereinafter, the stove burner specified in S72 may be referred to as a "specific stove burner."

In S74, the control unit 80 determines whether the specific stove burner is in operation. If the specific stove burner is not operating, the control unit 80 determines NO in S74, and the process returns to S70. On the other hand, if the specific stove burner is in operation, the control unit 80 determines YES in S74, and the process proceeds to S76.

In S76, the control unit 80 determines whether the thermal power of the specific cooking stove burner is greater than a predetermined minimum thermal power. The minimum firepower of a specific stove burner is the firepower when the firepower is reduced to the minimum. If the thermal power of the specific stove burner is greater than the minimum thermal power, the control unit 80 determines YES in S76, and the process proceeds to S78. On the other hand, if the thermal power of the specific stove burner is the minimum thermal power, the control unit 80 determines NO in S76, and the process proceeds to S80.

In S78, the control unit 80 reduces the firepower of the specific stove burner. When S78 ends, the process returns to S70.

In S80, the control unit 80 extinguishes the specific stove burner. When S80 ends, the process returns to S70.

Further, in S90, the control unit 80 monitors whether an object enters the gesture detection range. Specifically, the control unit 80 monitors, based on the image taken by the camera 92, whether an object other than the heated object enters the gesture detection range set in the setting process of FIG. If the camera 92 captures an image in which an object such as the user's clothing has entered the gesture detection range, the control unit 80 determines YES in S90, and the process proceeds to S92. On the other hand, if the camera 92 does not capture an image of an object such as the user's clothing entering the gesture detection range, the control unit 80 determines NO in S90, and the process returns to S70.

In S92, the control unit 80 extracts the motion (i.e. gesture) of the object that has entered the gesture detection range. Specifically, the control unit 80 extracts gestures of objects within the gesture detection range based on images continuously captured by the camera 92.

In S94, the control unit 80 uses the gesture list 88 in the memory 82 to perform processing according to the gesture extracted in S92 (for example, ignition of one of the cooking stove burners, extinguishing of the cooking stove burner in operation, (increase/decrease, etc.). When S94 ends, the process returns to S70.

(Specific cases A1 to A3)
Next, specific cases A1 to A3 realized by the process in FIG. 6 will be described with reference to FIGS. 8 to 10.

(Case A1)
In case A1, the object to be heated 180 is placed on the trivet 8a while the cooking device 2 is powered on. Moreover, all the stove burners 10a, 10b, and 10c are not operating. Further, the temperature of the heating target 180 is lower than the predetermined temperature.

The cooking device 2 first identifies the first cooking stove burner 10a as a specific cooking stove burner (S10 in FIG. 6). Next, the cooking device 2 determines that the object to be heated 180 is placed on the trivet 8a (YES in S20), and the interval between the object to be heated 180 and the gesture detection range is the first predetermined interval. The first exclusion range 132a is specified (S22). Next, the cooking device 2 determines that the temperature of the object to be heated 180 is less than the predetermined temperature (NO in S24), and does not specify the second exclusion range. Next, the cooking device 2 determines that the first stove burner 10a is not in operation (NO in S30), and does not specify the third exclusion range. Next, the cooking device 2 determines that the counter value N is not "3" (NO in S40), and counts up the counter value N to "2" (S42).

Next, the cooking device 2 identifies the second stove burner 10b (S10), determines that no object to be heated is placed on the trivet 8b (NO in S20), and determines that the second stove burner 10b is in operation. It is determined that this is not the case (NO in S30). In this case, the first exclusion range, the second exclusion range, and the third exclusion range corresponding to the second stove burner 10b are not specified. Next, the cooking device 2 determines that the counter value N is not "3" (NO in S40), and counts up the counter value N to "3" (S42).

Next, the cooking device 2 identifies the third stove burner 10c (S10), determines that no object to be heated is placed on the trivet 8c (NO in S20), and determines that the third stove burner 10c is in operation. It is determined that this is not the case (NO in S30). As in the case of the second stove burner 10b, the first exclusion range, second exclusion range, and third exclusion range corresponding to the third stove burner 10c are not specified. Next, the cooking device 2 determines that the counter value N is "3" (YES in S40).

Next, the heating cooker 2 determines that the first exclusion range 132a corresponding to the first cooking stove burner 10a has been specified (YES in S50), and selects the first exclusion range 132a from the gesture detection range 110 of the reference range information 86. A new gesture detection range 112 is set by excluding (S52). Further, the cooking device 2 adds the first exclusion range 132a to the first intrusion detection range 120a of the reference range information 86, and sets a new first intrusion detection range 122a (S52). In this case, the second intrusion detection range 120b and the third intrusion detection range 120c are not changed. Next, the cooking device 2 forms a three-dimensional image 152 on the boundary between the intrusion detection ranges 122a, 120b, and 120c and the gesture detection range 112, as shown in FIG. 8(b). The range within the three-dimensional image 152 is the gesture execution range when the heating target 180 is placed on the stove burner 10a.

(Case A2; Figure 9)
Case A2 in FIG. 9 is a state after case A1 in FIG. 8, and is a state immediately after the user ignites the first stove burner 10a and changes the thermal power of the first stove burner 10a to "high". . Note that at this point, the temperature of the heating object 180 is lower than the predetermined temperature.

The cooking device 2 first identifies the first cooking stove burner 10a as a specific cooking stove burner (S10 in FIG. 6). Next, the cooking device 2 determines that the object to be heated 180 is placed on the trivet 8a (YES in S20), and the interval between the object to be heated 180 and the gesture detection range is the first predetermined interval. The first exclusion range 132a is specified (S22). Next, the cooking device 2 determines that the temperature of the object to be heated 180 is less than the predetermined temperature (NO in S24), and does not specify the second exclusion range. Next, the cooking device 2 determines that the first stove burner 10a is in operation (YES in S30), specifies that the heat power of the first stove burner 10a is "high", and changes the heat power to "high". The corresponding third exclusion range 134a is identified (S32). Next, the cooking device 2 determines that the counter value N is not "3" (NO in S40), and counts up the counter value N to "2" (S42). After that, the same process as in case A1 is performed on the second stove burner 10b and the third stove burner 10c.

When the cooking device 2 determines that the counter value N is "3" (YES in S40), it determines that the first exclusion range 132a and the third exclusion range 134a corresponding to the first stove burner 10a have been specified. (YES in S50). In this case, since the third exclusion range 134a is larger than the first exclusion range 132a, the gesture detection range and the first intrusion detection range are reset using the third exclusion range 134a. The cooking device 2 excludes the third exclusion range 134a from the gesture detection range 110 in the reference range information 86 and sets a new gesture detection range 114 (S52). Further, the cooking device 2 adds the third exclusion range 134a to the first intrusion detection range 120a in the reference range information 86, and sets a new first intrusion detection range 124a (S52). Similar to case A1, the second intrusion detection range 120b and the third intrusion detection range 120c are not changed. Next, the heating cooker 2 forms a three-dimensional image 154 on the boundary between the intrusion detection ranges 124a, 120b, and 120c and the gesture detection range 114, as shown in FIG. 9(b). The range within the three-dimensional image 154 is the gesture execution range when the object to be heated 180 is placed on the cooking stove burner 10a and the cooking stove burner 10a is operating at "high" heating power.

(Case A3; Figure 10)
Case A3 is a state after case A2 in FIG. 9, and is a state after the user extinguishes the first stove burner 10a. Note that the temperature of the heating object 180 is higher than a predetermined temperature.

The cooking device 2 first identifies the first cooking stove burner 10a as a specific cooking stove burner (S10 in FIG. 6). Next, the cooking device 2 determines that the object to be heated 180 is placed on the trivet 8a (YES in S20), and the interval between the object to be heated 180 and the gesture detection range is the first predetermined interval. The first exclusion range 132a is specified (S22). Next, the cooking device 2 determines that the temperature of the object to be heated 180 is equal to or higher than a predetermined temperature (YES in S22), and specifies the second exclusion range 136a (S24). Next, the cooking device 2 determines that the first stove burner 10a is not in operation (NO in S30), and does not specify the third exclusion range. Next, the cooking device 2 determines that the counter value N is not "3" (NO in S40), and counts up the counter value N to "2" (S42). After that, the same process as in case A1 is performed on the second stove burner 10b and the third stove burner 10c.

When the cooking device 2 determines that the counter value N is "3" (YES in S40), it determines that the first exclusion range 132a and the second exclusion range 136a corresponding to the first stove burner 10a have been specified. (YES in S50). In this case, since the second exclusion range 136a is larger than the first exclusion range 132a, the gesture detection range and the first intrusion detection range are reset using the second exclusion range 136a. The cooking device 2 excludes the second exclusion range 136a from the gesture detection range 110 in the reference range information 86 and sets a new gesture detection range 116 (S52). Further, the cooking device 2 adds the second exclusion range 136a to the first intrusion detection range 120a in the reference range information 86, and sets a new first intrusion detection range 126a (S52). As in cases A1 and A2, the second intrusion detection range 120b and the third intrusion detection range 120c are not changed. Next, the cooking device 2 forms a three-dimensional image 156 on the boundary between the intrusion detection ranges 126a, 120b, and 120c and the gesture detection range 116, as shown in FIG. 10(b). The range within the three-dimensional image 156 is the gesture execution range when the heating target 180 is placed on the stove burner 10a and the temperature of the heating target 180 is equal to or higher than a predetermined temperature.

As described above, the heating cooker 2 includes the main body 4, the stove burner 10a that is provided on the upper part of the main body 4 and heats the object to be heated 180, and the camera that detects the user's movement in the gesture detection range on the main body 4. 92, LEDs 96a and 96b for displaying an image on the main body 4 indicating the gesture detection range in which the user should perform an action, and LEDs 96a and 96b for displaying an image on the main body 4 indicating the gesture detection range in which the user should perform an action, The control unit 80 is capable of controlling the operation and is also capable of controlling the operation of the LEDs 96a and 96b. The user using the heating cooker 2 can know the range in which the gesture should be executed by the three-dimensional image displayed on the main body 4. Therefore, it is possible to prevent the user from making a gesture near the cooking stove burner 10a and from touching the heating object 180 or the like with the user's hand. Therefore, the safety of the user who uses the heating cooker 2 can be improved.

In addition, the control unit 80 causes the LEDs 96a and 96b to display a three-dimensional image 150 indicating the gesture detection range 110 when the stove burner 10a is stopped (see FIG. 4(b)), and causes the stove burner 10 to operate. In this state, the LEDs 96a and 96b are configured to display a three-dimensional image 154 showing the gesture detection range 114 excluding the third exclusion range 134a near the stove burner 10a from the gesture detection range 110 (see FIG. 9(b)). According to the above configuration, the user does not perform a gesture in the third exclusion range 134a near the stove burner 10a while the stove burner 10a is in operation. Therefore, it is possible to prevent the user's hands from coming into contact with the heating object 180 and the like while the stove burner 10a is operating. Therefore, the safety of the user who uses the heating cooker 2 can be further improved.

Furthermore, the greater the firepower of the stove burner 10a, the greater the third exclusion range 134a. According to the above configuration, the greater the thermal power of the stove burner 10a, the larger the third exclusion range 134a near the stove burner 10a. For this reason, it is possible to further suppress the user's hands from coming into contact with the object to be heated 180 and the like while the stove burner 10a is operating. Therefore, the safety of the user who uses the heating cooker 2 can be further improved.

Further, the control unit 80 is configured to reduce the firepower of the stove burner 10a when a user's gesture is detected in the third exclusion range 134a while the stove burner 10a is operating. S78 in FIG. 7). According to the above configuration, when the user's hand enters the third exclusion range 134a, the heating power of the heating section is reduced. Therefore, when the user's hand enters the third exclusion range 134a, which is a high temperature area, the temperature in the third exclusion range 134a can be lowered. Therefore, the safety of the user who uses the heating cooker 2 can be further improved.

Further, the cooking device 2 may further include a camera 92 that can detect the size of the object to be heated 180. The control unit 80 displays a three-dimensional image 150 indicating the gesture detection range 110 on the LEDs 96a and 96b (see FIG. 4(b)) in a state where the object to be heated 180 is not placed on the stove burner 10a. In a state where the heated object 180 is placed on the burner 10a, a three-dimensional image 152 showing the gesture detection range 112 excluding the first exclusion range 132a near the stove burner 10a from the gesture detection range 110 is displayed by the LED 96a, 96b (see FIG. 8(b)). The larger the heated object 180 is, the larger the first exclusion range 132a is. According to the above configuration, the larger the heating target 180 is, the larger the first exclusion range 132a becomes, so that it is possible to suppress the user's hand from coming into contact with the heating target 180. Therefore, the safety of the user who uses the heating cooker 2 can be further improved.

Further, the cooking device 2 may further include a sensor 12a that detects the temperature of the object to be heated 180 placed on the stove burner 10a. The control unit 80 causes the LEDs 96a and 96b to display a three-dimensional image 150 showing the gesture detection range 110 in a state where the stove burner 10a is stopped and the temperature of the heating object 180 is less than a predetermined temperature (see FIG. 4(b)), when the stove burner 10a is stopped and the temperature of the object to be heated 180 is above the predetermined temperature, the second exclusion range 136a near the stove burner 10a is detected from the gesture detection range 110. The LEDs 96a and 96b are configured to display a three-dimensional image 156 showing the gesture detection range 116 excluding the gesture detection range 116 (see FIG. 10(b)). According to the above configuration, when the temperature of the heated object 180 is equal to or higher than the predetermined temperature, the three-dimensional image 156 showing the gesture detection range 116 excluding the second exclusion range 136a is displayed on the main body 4. Therefore, it is possible to suppress the user's hand from coming into contact with the heating target 180 in a state where the temperature of the heating target 180 is equal to or higher than the predetermined temperature. Therefore, the safety of the user who uses the heating cooker 2 can be further improved.

Furthermore, the image displayed on the main body 4 is a three-dimensional image formed on the main body. According to the above configuration, the user can more accurately grasp the gesture detection range. Therefore, the safety of the user who uses the heating cooker 2 can be further improved.

The stove burner 10, the camera 92, the LEDs 96a and 96b, and the sensor 12 are examples of a "heating section," an "operation detection section," a "display section," and a "detection section," respectively. The gesture detection range is an example of a "detection range". Gesture detection range 110, gesture detection range 114, gesture detection range 112, and gesture detection range 116 are respectively "first motion execution range", "second motion execution range", and "third motion execution range", This is an example of the "fourth action execution range." The third exclusion range, the first exclusion range, and the second exclusion range are examples of the "first specific range,""second specific range," and "third specific range," respectively.

(Second example)
With reference to FIGS. 11 to 13, the heating cooker 202 of the second embodiment will be described, focusing on the differences from the heating cooker 2 of the first embodiment. As shown in FIG. 11, the cooking device 202 of this embodiment differs from the cooking device 2 of the first embodiment in that it includes a speaker 294 (an example of a "notification section"). Moreover, the control unit 80 of the heating cooker 202 executes the process shown in FIG. 12 instead of the process shown in FIG. 6 . It should be noted that the same step numbers are given to processes that are common between the embodiments, and the description thereof will be omitted.

(Setting process; Figure 12)
In S50 of FIG. 12, the control unit 80 determines whether one or more exclusion ranges have been specified. If one or more exclusion ranges have been specified, the control unit 80 determines YES in S50, and the process proceeds to S52. On the other hand, if the exclusion range has not been specified, the control unit 80 determines NO in S50, and the process proceeds to S256.

In S256, the control unit 80 sets the gesture detection range 110 (see FIG. 4(a)) of the reference range information 86 in the memory 82 as the gesture detection range.

In S260, the control unit 80 determines whether the gesture detection range has been changed. If the previous gesture detection range and the current gesture detection range are different, the control unit 80 determines YES in S260, and the process proceeds to S262. On the other hand, if the previous gesture detection range and the current gesture detection range are the same, the control unit 80 determines NO in S262, and the process proceeds to S264.

In S262, the control unit 80 uses the speaker 294 to notify that the gesture detection range has been changed.

In S264, the control unit 80 changes the counter value N to "1". When S264 ends, the process returns to S10.

(Specific case B; Figure 13)
Next, with reference to FIG. 13, a specific case B realized by the process of FIG. 12 will be described. Case B is a state immediately after the user changes the heat power of the first stove burner 10a to "high". Note that at this point, the temperature of the heating object 180 is lower than the predetermined temperature.

The cooking device 2 first identifies the first cooking stove burner 10a as a specific cooking stove burner (S10 in FIG. 12). Next, the cooking device 202 determines that the object to be heated 180 is placed on the trivet 8a (YES in S20), and the interval between the object to be heated 180 and the gesture detection range is the first predetermined interval. The first exclusion range 132a is specified (S22). Next, the cooking device 202 determines that the temperature of the object to be heated 180 is less than the predetermined temperature (NO in S24), and does not specify the second exclusion range. Next, the cooking device 202 determines that the first stove burner 10a is in operation (YES in S30), specifies that the heat power of the first stove burner 10a is "high", and changes the heat power to "high". The corresponding third exclusion range 334a is identified (S32). Next, the cooking device 202 determines that the counter value N is not "3" (NO in S40), and counts up the counter value N to "2" (S42). After that, the same process as in case A1 is performed on the second stove burner 10b and the third stove burner 10c.

When the cooking device 202 determines that the counter value N is "3" (YES in S40), it determines that the first exclusion range 132a and the third exclusion range 334a corresponding to the first cooking stove burner 10a have been specified. (YES in S50). In this case, since the third exclusion range 334a is larger than the first exclusion range 132a, the gesture detection range and the first intrusion detection range are reset using the third exclusion range 334a. The heating cooker 202 excludes the third exclusion range 334a from the gesture detection range 110 in the reference range information 86 and sets a new gesture detection range 314 (S52). Further, the cooking device 2 adds the third exclusion range 334a to the first intrusion detection range 120a in the reference range information 86, and sets a new first intrusion detection range 324a (S52). Similar to case A1, the second intrusion detection range 120b and the third intrusion detection range 120c are not changed. Next, the cooking device 202 uses the speaker 294 to notify that the gesture detection range has been changed (S262). Specifically, the cooking device 202 notifies that the gesture detection range on the first cooking stove burner 10a side has become narrower. This allows the user to know that the gesture detection range has been changed.

As described above, the heating cooker 202 includes the main body 4, the stove burner 10a that is provided on the upper part of the main body 4 and heats the object to be heated 180, and the camera that detects the user's movement in the gesture detection range on the main body 4. 92, and a control unit 80 capable of controlling the operation of the stove burner 10a based on the user's movement within the gesture detection range, and the control unit 80 is configured to control the operation of the stove burner 10a when the stove burner 10a is stopped. , the gesture detection range 110 is set (see FIG. 4(a)), and when the stove burner 10a is operating, gesture detection is performed by excluding the third exclusion range 334a near the stove burner 10a from the gesture detection range 110. It is configured to set a range 314 (see FIG. 13). According to the above configuration, when the stove burner 10a is operating, even if the user's gesture is executed in the third exclusion range 334a, the cooking device 202 does not operate the stove burner 10a based on the user's gesture. not control. Therefore, the user no longer performs gestures in the third exclusion range 334a. Therefore, it is possible to prevent the user's hands from coming into contact with the object to be heated 180 and the like while the stove burner 10a is in operation. As a result, the safety of the user who uses the heating cooker 202 can be further improved.

Furthermore, the greater the firepower of the stove burner 10a, the greater the third exclusion range 334a. According to the above configuration, the greater the thermal power of the stove burner 10a, the larger the third exclusion range 334a near the stove burner 10a. For this reason, it is possible to further suppress the user's hands from coming into contact with the object to be heated 180 and the like while the stove burner 10a is operating. Therefore, the safety of the user who uses the heating cooker 202 can be further improved.

The cooking device 202 further includes a speaker 294, and the control unit 80 can control the operation of the speaker 294. The control unit 80 is configured to, when the size of the gesture detection range is changed (YES in S260 of FIG. 12), make the speaker 294 notify that the size of the gesture detection range has been changed ( S262). According to the above configuration, the user can know that the size of the gesture detection range has been changed. Therefore, the user can be prevented from performing gestures in the third exclusion range 334a at an early stage. Therefore, the safety of the user who uses the heating cooker 202 can be further improved.
