  As the notification means 30 for notifying the operation heating state of each heating element 2, the light emitting element 22 lights up in the individual state display part of each heating element 2 provided in front of the pan placement position display part 20 of each heating element 2. Is displayed.

  Further, in the present embodiment, as shown in FIG. 1, an individual operation switch 7 including a single heating on / off switch 7a and a heating power adjustment switch 7b is arranged in front of the individual state display section.

  In addition, the bridging notification means 8 for displaying the bridging state is provided by the light emitter 23 in the bridging display unit provided in front of the two mounting position display units 20 constituting the heating element pair 10. Lights up.

  A bridging heating on / off switch 6 is disposed in front of the bridging notification means 8 on the stove top 12.

  As the heating element upper pan detecting means 4 and the heating element pan detecting means 5 for detecting the presence or absence of the heated body 3, the presence or absence of the heated body 3 is conventionally known in a non-contact type or a contact type. Although various technologies for detection can be employed, the embodiment shown in FIGS. 1 to 7 shows an example in which the heating element upper pan detection means 4 is configured by a pair of electromagnetic induction coils 14 constituting the heating element 2. is there.

  In this example, when a weak output is given to the electromagnetic induction coil 14, a coil eddy current is generated when there is a pan on the electromagnetic induction coil 14. Therefore, by detecting this coil eddy current, it is determined that there is a pan. If no coil eddy current is generated, it is determined that there is no pan.

  Moreover, in embodiment shown in FIG. 1 thru | or FIG. 7, the example which comprised the heating element between-pans detection means 5 with the reflection type photoelectric (infrared) sensor is shown.

  This reflective photoelectric (infrared) sensor is configured by arranging a light emitting element that emits infrared rays and a light receiving element in the main body 18, and the infrared rays emitted from the light emitting elements pass through the stovetop 12. Then, the light is reflected on the bottom surface of the heated body 3, passes again through the stove top plate 12, is received by the light receiving element, and the received light output is input to the control unit 11. To come to judge.

  In addition, in the embodiment shown in FIGS. 1 to 7, an infrared radiation sensor is used as the heating element upper temperature detection means 9 a and the heating element inter-temperature detection means 9 b, and in the area of each placement position display unit 20, and It arrange | positions in the main-body part 18 of the position between the two heat generating bodies 2 used as the pair which comprises the heat generating body pair 10. FIG.

  The stove device 1 of the present invention having the above-described configuration is a single heating operation mode in which the thermal power output control of each heating element 2 is independently performed, and the two heating elements 2 forming a pair constituting the heating element pair 10 are bridged. It has a heating operation mode.

  That is, by operating the bridging heating on / off switch 6, the two heating elements 2 forming a pair constituting the heating element pair 10 as shown in the flowchart shown in FIG. 3 are heated in the bridging heating operation mode. The output is synchronized and controlled.

  Further, by operating each individual operation switch 7, each heating element 2 is controlled independently in the single heating operation mode to perform the single heating operation as shown in the flowchart shown in FIG.

  Hereinafter, the transfer heating operation mode will be described with reference to FIG. 1 and 2 are a plan view and a schematic cross-sectional view in the state of the bridging heating operation mode, and FIG. 4 is a notification example by the individual notifying means 30 and the bridging notifying means 8 in each stage of the bridging heating operation mode. Show.

  First, when a power switch (not shown) provided in the stove device 1 is turned on, a standby state is entered.

  In the case of performing the overheating operation, the overheating heating on / off switch 6 is turned on in the standby state.

  When the bridging heating on / off switch 6 is turned on, it is detected whether or not there is a pan in the middle of the heating element pair 1 by a reflection type photoelectric (infrared) sensor constituting the heating element inter-pan detection means 5. At this time, it is displayed at the same time by the bridging notification means 8 that the bridging state is being determined (for example, as shown in FIG. 4A, a part of the bridging notification means 8 and the adjacent individual notifying means 30. Part of is flashing).

  As described above, when it is detected that the pan between the heating elements 2 is detected by the heating element pan detection means 5, the electromagnetic induction coil 14 (that is, the pair of the heating elements 2 constituting the adjacent heating element 2 (that is, the electromagnetic induction coil 14). A weak output is output to each heating element upper pan detection means 4) to determine the presence or absence of the pan.

  When the presence of the pan is detected at the three places of the heating element pan detecting means 5 and the left and right heating element upper pot detecting means 4 in this way, the bridging heating operation mode is determined and the bridging notification means 8 A notification is displayed that the transfer is confirmed. For example, as shown in FIG. 4B, a part of the light emitting body 23 of the crossing notification means 8 and a part of one of the individual notification means 30 of the heating element pair 10 are always lit and “crossing confirmation notification”. Is displayed.

  On the other hand, when the pan is not detected by the heating element pan detection means 5, or when the left and right of the heating element pair 10 or both the heating element upper pot detection means 4 does not detect the pan, it is assumed that the bridging has failed. Then, the “crossover failure warning” is notified by the crossover notification means 8.

  For example, as shown in FIG. 4D, all the light emitters 23 of the bridging notification means 8 are blinked, and a part of the light emitters 22 of the individual notification means 30 on the side where an abnormality is detected is blinked.

  Further, as described above, the “crossover failure warning” is notified, and at the same time, the output of the heating element pair 10 to the left and right electromagnetic induction coils 14 is stopped, and the standby state is entered.

  Thus, in the present invention, when the pan is not correctly bridged between the left and right heating elements 2 constituting the pair of heating elements 10, that is, the pot is placed only on one heating element 2. If a different pan is placed on each of the heating elements 2 that are paired with the heating element pair 10 and no pan is detected between the heating elements 2, the pair constituting the heating element pair 10 Heat is not output to both of the heating elements 2 that have become, and safety is ensured by shifting to standby.

  As described above, the present invention enters the bridging heating operation mode only when the presence of the pan is detected at three locations by the heating element pan detection means 5 and the adjacent left and right heating element upper pot detection means 4.

  When the bridge heating operation mode is determined, one of the left and right individual operation switches 7 of the heating element pair 10 (right side in the figure) and the individual notification switch 30 are invalidated and the other (left side in the figure). The thermal power adjustment switch 7b of the individual operation switch 7) is controlled to substitute for the thermal power adjustment switch in the bridge heating operation mode.

  In the embodiment, the individual heating on / off switch 7a of the other individual operation switch 7 (left side in the figure) is invalidated. At this time, the fact that the other thermal power control switch 7b substitutes for the thermal power control switch in the bridge heating operation mode indicates that a part of the other (not shown in the figure) individual notification means 30 as shown in FIG. 4B. Display by turning on.

  Next, the heating power adjustment of the left and right heating elements 2 can be performed by operating the other heating power control switch 7b (the left side in the figure) that has been substituted, and the heating power outputs of the left and right heating elements 2 are controlled synchronously. Then, heating operation is performed.

  As shown in FIG. 4C, the thermal power adjustment display in the bridging heating operation mode is level-displayed by a plurality of light emitters 23 of the bridging notification means 8.

  As described above, the heating operation is performed by heating over a large or horizontally long heated object such as a large pan, a large iron plate, or a horizontally long fish roasting pan.

  During this bridging heating operation, the left and right heating element upper pan detecting means 4 detects the presence or absence of the object to be heated 3, and the heating element between the adjacent heating elements 2 by the heating element pan detecting means 5 is detected. 3, and the temperature at the bottom of the pot positioned on each heating element 2 of the heated body 3 that is being heated by heating and the temperature at the bottom of the pot between the heating elements 2 are respectively detected on the heating element temperature detecting means 9 a, The temperature is detected by the heating element temperature detection means 9b.

  The presence of the pan is confirmed by all of the right and left heating element upper pan detection means 4 and the heating element inter-pan detection means 5, and it is detected that the spanning state is maintained. In addition, three temperature detection means The temperature of the left and right side portions and the middle portion of the pan 3 of the heated body 3 that is being heated over the heating is detected by the (heating element upper temperature detection means 9a, inter-heating element temperature detection means 9b), and the above three detected temperatures Is within the set temperature range, the above-described overheating operation is continued until the overheating heating on / off switch 6 is turned off.

  Further, although not shown in the flow diagram, the correlation between the temperature detection values of the two heating element temperature detection means 9a and the temperature detection means 9b between the heating elements located between them is a value within a preset range. When the deviation is detected, it is determined that the heating unevenness due to the influence of ingredients in the pan, etc., and in order to correct this unevenness, the output to any one of the heating elements 2 of the heating element pair 10 is increased or decreased, It is also possible to control the deviation of the heating amount of the heating element pair 10 so as to eliminate the uneven heating.

  On the other hand, during the bridging heating operation, the presence of the pan (object) is not detected by at least one of the adjacent left and right heating element upper pan detection means 4 and the heating element inter-pan detection means 5, or three places Of the temperatures detected by the temperature detecting means 9 (heating element upper temperature detecting means 9a, inter-heating element temperature detecting means 9b), if at least one temperature is outside the set range, the heating element pair 10 Each output to the heating element 2 that forms a pair is stopped and a standby state is entered. As a result, when the pan is moved during the overheating operation or when abnormal heating occurs, the output is stopped to ensure safety.

  In the present embodiment, one of the thermal power adjustment switches 7b that individually adjusts the thermal power of the two heating elements 2 is used as a thermal power adjustment switch in the bridge heating operation mode, so that the number of switches can be reduced. Thus, the structure can be simplified. Of course, a dedicated switch may be provided as a heating power adjustment switch in the bridge heating operation mode.

  Next, the single heating operation mode will be described with reference to FIG. 5 shows a schematic cross-sectional view in the single heating operation mode state, and FIG. 7 shows a notification example by the individual notification means and the bridging notification means in each stage of the single heating operation mode.

  A power switch (not shown) provided in the stove device 1 is turned on to enter a standby state, and then the single heating on / off switch 7a of the heating element 2 to be used is turned on.

  When the single heating on / off switch 7a is turned on, it is detected whether or not an object such as a pan exists between the adjacent heating elements 2 by the reflection type photoelectric (infrared) sensor constituting the heating element pan detecting means 5.

  At this time, the corresponding individual notification means 30 notifies that the individual heating on / off switch 7a is turned on (for example, a part of the corresponding individual notification means 30 blinks as shown in FIG. 7A). Display).

  When it is detected by the heating element pan detecting means 5 that an object such as a pan is present, the stand-by state is returned to the state that it is abnormal as single heating. In this case, for example, as shown in FIG. 7 (e), the corresponding individual notification means 30 blinks entirely, and a part of the transfer notification means 8 blinks, so that the pan is alone on the corresponding heating element 2. Notify that it is not placed correctly.

  Compared to a conventional stove, even when the heating element 2 is used alone, safety alerts are also given to the presence of an inadvertent object around the heating element 2, that is, between the two heating elements 2. Notification can be performed, which is more preferable.

  On the other hand, when there is no pan in the heating element pan detection means 5, there is a pan by weakly outputting to the electromagnetic induction coil 14 (which respectively constitutes the heating element upper pan detection means 4) constituting the heating element 2 to be used. Determine whether or not. When it is detected that there is a pan on each heating element 2, the single heating operation mode is confirmed.

  When the single heating operation mode is determined as described above, the pan detection determination is notified by the individual notification means 30. In this case, for example, as shown in FIG. 7B, a part of the individual notification means 30 is turned on to notify “pan detection confirmation”.

  Next, the heating power adjustment switch 7b is operated to adjust the heating power of the heating element 2, and a single heating operation is performed. The display of the heating power adjustment in the single heating operation mode is displayed by the individual notification means 30 as shown in FIG.

  When the presence of the pan is confirmed by the heating element upper pan detection means 4 and when the temperature of the bottom of the heated body 3 is detected by the heating element upper temperature detection means 9a, the temperature is within the set temperature range. The single heating operation is continued until the heating on / off switch 7a is turned off.

  On the other hand, when the presence of the pan is not detected by the heating element upper pan detection means 4 during the single heating operation, or the temperature detected by the heating element upper temperature detection means 9a is outside the set temperature range. For example, as shown in FIG. 7 (d), the individual notification means 30 blinks completely to notify that the pan is “no pan / non-conformity”, stops the output to the heating element 3 and shifts to a standby state. .

  Further, during the single heating operation, if it is determined that the pan between the heating elements detecting means 5 or the temperature detecting means 9b between the heating elements is abnormal, there is no problem even if the control for stopping the coil output of the heating element 2 is used. Absent.

  In addition, the content of the display in the bridge | bridging alerting | reporting means 8 and the separate alerting | reporting means 30 in each step of the bridging heating operation mode and the individual heating operation mode is not limited to the above-described example.

  Moreover, you may provide not only a visual display means but an audio | voice alerting | reporting means collectively.

  Next, another embodiment of the present invention will be described with reference to FIGS.

  In each of the above-described embodiments, the example in which the heating element 2 is configured by the electromagnetic induction coil 14 has been shown, but this embodiment shows an example of a so-called gas stove in which the heating element 2 is configured by the combustion burner 16.

  As shown in FIGS. 8, 9, and 11, a plurality (three in the figure) of combustion burners 16 and their five virtues 26 are arranged in parallel in the left-right direction so as to be exposed to the stove top 12.

  The heating element upper pan detection means 4 in the present embodiment uses a contact type that detects the presence or absence of the heated body 3 by contacting the bottom surface (pan bottom) of the heated body 3. The heating element upper pan detection means 4 is composed of a movable part 27 that is vertically movable and spring-biased upward and a limit switch (not shown) that is turned on / off by the vertical movement of the movable part 27. Is configured.

  When the heated object 3 is placed on the virtues 26 and the heated object 3 comes into contact with the movable part 27, the heating element upper pan detecting means 4 is pushed down against the spring force and the limit switch is turned on. When it is turned on and the signal is input to the control unit 11, it is determined that the heated body 3 exists, and when the heated body 3 is separated from the virtues 26, the movable unit 27 moves upward by a spring force. Thus, the limit switch is turned off and it is determined that the heated object 3 does not exist.

  In addition, as the heating element pan detecting means 5 in the present embodiment, for example, a proximity sensor or a distance measuring sensor is used.

  Further, in the present embodiment, a contact type thermistor is provided on the movable portion 27 as the heating element temperature detecting means 9a for detecting the temperature of the pan bottom located on each heating element 2 corresponding to each heating element 2. It consists of that. An infrared radiation sensor is used as the inter-heating element temperature detecting means 9b for detecting the temperature of the pan bottom above the pair of heating elements 2 constituting the heating element pair 10.

  FIG. 10 shows a flow in the bridge heating operation mode in the present embodiment, and FIG. 12 shows a flow in the single heating operation mode in the present embodiment.

  In the present embodiment, as shown in FIG. 10, the pan detection is simultaneously performed by the pan between the heating element detecting means 5 using the non-contact type sensor and the two heating element upper pot detecting means 4 using the contact type sensor.

  Although the above points are different, the rest is controlled by the same flow as the flow of the bridge heating operation mode in the above-described embodiment shown in FIG.

  Further, in the case of a gas stove, both flames are mixed in the middle of the pair of heating elements 10, that is, between both combustion burners 16, and only a single radiant type inter-heating element temperature detection means 9b is used. Due to the difficulty in detecting the temperature, the temperature detecting means for contact with the heated body 3 used on each heating element 2, the means for detecting the flame temperature, or the waste gas components around the flame are detected. It is also preferable to provide a combination of means for monitoring combustion abnormality.

  In each of the embodiments described above, the heating element upper pan detection means 4 and the heating element pan detection means 5 which are means for detecting whether or not the heated body 3 is placed are the electromagnetic induction coil 14 or the movable part. Although an example of a pan detection switch that is turned on and off by a vertical movement of 27, a reflection photoelectric (infrared) sensor, a proximity sensor, or a distance measuring sensor is shown, it is not necessarily limited to the above example. Instead, the presence / absence of the object to be heated 3 may be detected by the amount of light received by the stove top 12.

  In order to detect the amount of light received by the stove top plate 12, a light reception amount sensor is provided immediately below each mounting position display unit 20 or between adjacent mounting position display units 20 on the stove top plate 12, and a stove device is provided. The amount of light received from the surrounding environment where the stovetop 1 is installed is detected by the above-mentioned received light amount sensor. If the heated body 3 is present at a position between the placement position display units 20 and the light amount is blocked, it is determined that the heated body 3 is placed at a predetermined position of the stove top 12 and the light amount is blocked. First, when a predetermined amount of light is received by the light receiving sensor, it is determined that the heated object 3 is not placed.

  In particular, in the case of an electric stove such as an electromagnetic induction heating (IH) type, since the pot and the stove top 12 are in close contact with each other, the above method is simple and effective.

  Of course, in addition to those exemplified above, the presence / absence of an object to be heated may be detected using a conventionally known pan detecting means. Further, a plurality of these examples may be combined. In this case, the presence or absence of the heated body 3 can be detected more accurately.

  In any of the above embodiments, in performing the synchronous interlocking control of the heating elements 2 constituting the heating element pair 10 in the heating operation in the bridge heating operation mode, the outputs of both the heating elements 2 are not changed. And the same output synchronization mode for synchronously controlling the same output and different output synchronization for controlling the output of one of the left and right heating elements 2 to be larger or smaller than the output of either the left or right heating element 2 A control mode, and the output synchronization mode and the different output synchronization control mode may be selectable.

  Here, when the bridge heating operation mode is operated in the different output synchronous control mode, when the heating operation is performed in the bridge heating operation mode, deviation heating of the left and right heating elements 2 can be performed, for example, the head of the fish is strongly heated. Or the foodstuff which is easy to pass heat with the same to-be-heated body 3, and the foodstuff which is hard to pass heat can be cooked simultaneously.

  In any of the above-described embodiments, as shown in FIGS. 1, 4, 6, 8, and 13, three heating elements 2 are arranged in parallel in the left-right direction, and one heating element located on one side. 2 is a large thermal power and has a large area, and the other two adjacent heating elements 2 have a small thermal power and a smaller area than the above-mentioned large thermal power. The heating element 2 may have the same heating power, one may be a medium heating power smaller than the above large heating power, and the other may be a small heating power smaller than the medium heating power). The example which comprises the body pair 10 is shown. Then, the adjacent small-fired heating elements constituting the heating-element pair 10 that enables the bridge heating than the pitch between the large-fired heating element 2 and the intermediate small-fired heating element 2 adjacent thereto. The pitch between the two is made small, and it is constructed so as to be convenient for bridging the heated body 3 between two adjacent heating elements 2 of small thermal power.

  In these embodiments, the rear ends of the heating element 2 with a large thermal power and a large area and the heating element 2 with a small thermal power and a small area are aligned or substantially aligned on an imaginary line parallel to the front edge of the stovetop 12. With this, a large space in front of the heating element 2 with a small heating power and a small area can be secured, and in particular, it can be used for various purposes such as temporarily placing a horizontally long pan used for overcooking cooking in the space in front. It is like that.

  In each of the above-described embodiments, an example in which three heating elements 2 are arranged in parallel has been shown. However, in the present invention, even when two heating elements 2 are arranged in parallel, four or more heating elements 2 are arranged in parallel. Of course, things can be used.
