  However, the conventional configuration has a plurality of overlapping operation units of the first operation unit 21 and the second operation unit 23 to control the heating unit 18, and this is an expensive configuration. Had. In addition, when an input operation is prohibited by the second operation unit 23 below the top plate 17, a heating operation cannot be started by operating a switch on the same surface as the top plate. Also had.

  The present invention solves the above-described conventional problem, and when a predetermined time elapses without heating operation or switch input, a standby mode for prohibiting inputs other than the specific switch arranged on the top plate is set for each of the plurality of heating means. Even when the device is in the standby mode, it is easy to use and can be heated only by a switch on the top plate, and the first operation part of the conventional example is not required and inexpensive. It is an object of the present invention to satisfy both the configuration and the erroneous input suppression of the switch input of the top plate arrangement.

In order to solve the above-described conventional problems, a heating cooker according to the present invention heats a body constituting an outer shell, a top plate provided on an upper surface of the main body, and an object to be heated placed on the top plate. a first heating means and second pressure heat means, the first input switch group for controlling the first pressure heat means provided on the top plate and substantially flush, provided on the top plate and substantially flush the a second input switch group for controlling the second pressurizing heat means, a first heating mode in which the heating operation of the first heating means, and a second heating mode in which the heating operation of the second heating means, said first A first initial mode capable of stopping the heating operation of the heating means and shifting to the first heating mode by the input of the first input switch group; and the heating operation of the second heating means is stopped and the second input switch A second initial mode that can be shifted to the second heating mode by group input. Comprising a de, and input to the the mode of said first input switch group said first input invalid and vital first specific switch input switch group except for a single one first specific switch in the a first standby mode and releasing operation is performed to shift to the first initial mode, before Symbol second except for single second specific switch in the input switch group invalidates the input of the second input switch group and the second when the input of a specific switch-mode release operation is performed to have a, a second standby mode to shift to the second initial mode transition after the first heating means to said first initial mode Shifts to the first standby mode when it does not shift to the first heating mode for a predetermined time, and shifts to the second standby mode when it does not shift to the second heating mode for a predetermined time after shifting to the second initial mode. And the first specific scan Pitch is also used input functions other than release of the first standby mode, the second specific switch is obtained by alternate input function other than release of the second standby mode.

Further, during the standby mode, the number of switch inputs that can be made is limited to a single number, so that unintended operation mode transition can be suppressed. In addition, even when the device enters a standby mode in which the operation of the input switch on the top plate is suppressed to prevent erroneous input, the standby mode can be canceled only by the switch on the top plate and the heating operation can be performed. Can provide a good cooker.

In addition, in order to release the operation prohibition state of the switch on the top plate, the input switch for operating the heating means is conventionally arranged overlappingly on the top plate and further not on the top plate. In this case, since the return from the machine mode is performed by a specific switch on the top board, a switch for operating the heating means in a place not on the top board becomes unnecessary and the construction becomes inexpensive. In addition, since the switch that performs the release operation is also used as another function, it is not necessary to provide a dedicated switch, and the configuration is inexpensive.

The cooker of the invention, when a predetermined time has elapsed with no heating operation, by providing the standby mode for prohibiting an input except for certain switch located on the top board, with one erroneous input in a standby mode not be moved to a heating operation, it is useful from the viewpoint of safety, released and allowed to heating operation standby mode only a switch which is also used with other functions on the top plate even if the device is in standby mode In addition to improving usability, there is no need to provide a dedicated switch for canceling the standby mode, and there is a standby mode for each heating means, which improves the effect of suppressing incorrect input of switch inputs on the top panel. Can be made.

The first invention includes a body constituting an outer shell, a top plate provided on an upper surface of the main body, and a first heating means and second pressure heat means for heating the object to be heated placed on the top plate a second input switch for controlling the first input switch group, the second pressurizing heat means provided on the top plate and substantially flush for controlling said first pressure heat means provided on the top plate and substantially flush A group , a first heating mode for performing the heating operation of the first heating means, a second heating mode for performing the heating operation of the second heating means, and stopping the heating operation of the first heating means to perform the first input. A first initial mode capable of shifting to the first heating mode by an input of a switch group, and a heating operation of the second heating means are stopped, and a transition to the second heating mode is performed by an input of the second input switch group. it and a second initial mode which may, of said first input switch group The to the input of the disabled and vital first specific switch input of the first except for the specific switch said first input switch group of single is mode releasing operation is performed the transition to the first initial mode a first standby mode, the input of the pre-Symbol second input switch group and the second input disables the vital second particular switch input switch group except for a single one second specific switch in is the mode of a second standby mode in which the cancellation operation is performed to shift to the second initial mode, have a, when the said rear transition to the first initial mode first heating means does not shift a predetermined time in the first heating mode, the When shifting to the first standby mode and not shifting to the second heating mode for a predetermined time after shifting to the second initial mode, the mode shifts to the second standby mode, and the first specific switch moves to the first standby mode. Other than canceling Also serves as a force function, said second particular switch by alternate input function other than release of the second standby mode in the standby mode, not be moved to a heating operation in a single erroneous input, safety It is useful from the standpoint of ensuring safety. Further, during the standby mode, the number of switch inputs that can be made is limited to a single number, so that unintended operation mode transition can be suppressed. In addition, even when the device enters a standby mode in which the operation of the input switch on the top plate is suppressed to prevent erroneous input, the cooking mode is easy to use so that the standby mode can be canceled only with the switch on the top plate. Can be provided.

In addition, in order to release the operation prohibition state of the switch on the top plate, the input switch for operating the heating means is conventionally arranged overlappingly on the top plate and further not on the top plate. In this case, since the return from the standby mode is performed by a specific switch on the top board, a switch for operating the heating means in a place not on the top board becomes unnecessary and the construction becomes inexpensive. In addition, since the switch that performs the release operation is also used as another function, it is not necessary to provide a dedicated switch, and the configuration is inexpensive. Furthermore, by having the first and second standby modes individually, for example, even when the first heating means is heating, if the second heating means is not heated, the second heating means is set after a predetermined time. It shifts to the 2nd standby mode which suppressed the input concerned, and the possibility of the erroneous input of the switch on a top plate can be controlled. On the contrary to the above-mentioned operation, even when the second heating means is heating, if the first heating means is not heated, after a predetermined time, it shifts to the first standby mode in which the input related to the first heating means is suppressed. In this way, by having a stand-by mode for each heating means, it is possible to suppress the operation of the switch on the top panel according to actual use, and it is possible to prevent erroneous input of the top panel switch without impairing usability. Can be suppressed.

2nd invention, the main body which comprises an outer shell, the top plate provided in the upper surface of the said main body, the 1st heating means and the 2nd heating means which heat the to-be-heated object mounted on the said top plate, A first input switch group that is provided on substantially the same plane as the top plate and controls the first heating means; a second input switch group that is provided on substantially the same plane as the top board and controls the second heating means; A first heating mode in which the heating operation of the first heating means is performed; a second heating mode in which the heating operation of the second heating means is performed; and the heating operation of the first heating means is stopped and the first input switch group The first initial mode that can be shifted to the first heating mode by input, and the heating operation of the second heating means can be stopped and the second heating mode can be shifted to by the input of the second input switch group. A second initial mode, wherein the first input switch group Except for the plurality of first specific switches, when the input of the first input switch group is invalidated and when the input of the first specific switch is input, a mode canceling operation is performed and a transition to the first initial mode is made. When the input of the second input switch group is invalidated and the input of the second specific switch is made invalid except for the mode and a plurality of second specific switches in the second input switch group, the mode release operation is performed. A second standby mode for shifting to the second initial mode, and when the first heating means does not shift to the first heating mode for a predetermined time after shifting to the first initial mode, the first standby mode is entered. When the transition to the second initial mode does not proceed to the second heating mode for a predetermined time, the transition to the second standby mode is made and the first specific switch is turned on except for the release of the first standby mode. Since the second specific switch is a heating cooker that also functions as an input function other than the release of the second standby mode, it is possible to shift to a heating operation with a single erroneous input in the standby mode. It is useful from the viewpoint of ensuring safety. In addition, since the switch that performs the release operation is also used as another function, it is not necessary to provide a dedicated switch, and the configuration is inexpensive. In addition, even when the device enters a standby mode in which the operation of the input switch on the top plate is suppressed to prevent erroneous input, the standby mode can be canceled only by the switch on the top plate and the heating operation can be performed. Can provide a good cooker.

According to a third aspect of the present invention, in particular, in the first aspect, when the first heating means does not shift to the first heating mode for a predetermined time after shifting to the first initial mode, the first standby mode is shifted to the second initial mode. Instead of shifting to the second standby mode when not shifting to the second heating mode after shifting to the second heating mode, the first heating means does not shift to the first heating mode for a predetermined time after shifting to the first initial mode. when there is no input from the time the first input switch group, prior SL shifts to the first standby mode, wherein the migration post the second heating mode the second initial mode without going predetermined time and a predetermined time second input switch group when there is no input from, by pre SL shifts to the second standby mode in the standby mode, not be moved to a heating operation in a single erroneous input is useful from the viewpoint of safety. An easy-to-use cooking device that can release the standby mode only with the switch on the top plate even when the device enters the standby mode in which the operation of the input switch on the top plate is suppressed to prevent erroneous input. Can be provided.

In addition, in order to release the operation prohibition state of the switch on the top plate, the input switch for operating the heating means is conventionally arranged overlappingly on the top plate and further not on the top plate. in, by causing the return from the standby mode in particular switch on the top plate, the switch becomes a low-cost structure becomes unnecessary to operate the heating means to a location not on the top plate. In addition, since the switch that performs the release operation is also used as another function, it is not necessary to provide a dedicated switch, and the configuration is inexpensive.

  Furthermore, by separately having the first and second standby modes, for example, even when the first heating means is heating or operating the first input switch, the second heating means is kept in the non-heated state and the second input is performed. If the switch is not operated, after a predetermined time, the mode is shifted to the second standby mode in which the input related to the second heating means is suppressed, and the possibility of erroneous input of the switch on the top plate can be suppressed. Contrary to the above operation, when the second heating means is heating or operating the second input switch, the first heating means is not heated and the first input switch is not operated. The process shifts to the first standby mode in which the input related to the first heating means is suppressed. In this way, by having a stand-by mode for each heating means, it is possible to suppress the operation of the switch on the top panel according to actual use, and it is possible to prevent erroneous input of the top panel switch without impairing usability. Can be suppressed.

The fourth invention is the first display means for displaying the fact when the first standby mode is in the first standby mode, and the second standby mode, in any one of the first to third inventions, By having the second display means for displaying that, it is possible to easily let the user know which of the first heating means and the second heating means suppresses the input by the top switch. In addition, usability is further improved.

A fifth invention is, in particular, in the first to fourth one of the invention, comprise other heating means for heating the object to be heated placed on the top plate, provided on the top plate and substantially flush said other heating and other input switches that control means, said other other heating mode for heating operation of the heating means and the other heating at the input of the heating operation was stopped the first other input switches of the other heating means is The other initial mode that can be shifted to the mode, and the input of the other input switch group is invalidated except the input of the other specific switch in the other input switch group and the other specific switch is input. and other standby mode to shift to the initial mode, by as having other display means for displaying the fact when in the other standby mode, even in the heating cooker having a heating means or a three-necked, waiting In mode Not be moved to a heating operation at times of input errors, it is useful from the viewpoint of safety. In addition, when the device is in standby mode, the standby mode can be canceled and heated by using only the switch on the top plate, improving usability and providing a standby mode for each heating means. The effect of suppressing erroneous input of the switch input can be improved.

  A cooking device having the configuration of FIG. 1 will be described below with reference to the drawings.

FIG. 2 shows a detailed configuration of the left switch portion, which is the first switch group , and a switch detection signal. Each switch includes a conductive front electrode and a back electrode, and an insulator (here, glass). It is a capacitor | condenser structure which pinched | interposed the top plate 2 comprised by these. The surface electrode is formed on the same surface as the outer surface of the top plate 2 so that the user can easily operate it. When a person's finger touches the surface electrode, the charge stored in the capacitor structure described above is transferred to the human body. As shown in FIG. 2, the switch detection signal varies from v1 (4V here) to v2 (2V here) as shown in FIG. Acceptance of the switch is valid when a fluctuation voltage exceeding a preset voltage fluctuation threshold Vθ (here 1V) is continuously input for a preset time tθ, and the left down switch 5a, The up switch 5b, the left heating off / on switch 5c, the left timer switch 5d, and the left cancellation switch 5e output an effective signal to the control means 7.

And the control means 7 controls the left heating coil 3 and the left liquid crystal display device 8a based on an effective switch input. The configuration of the right switch section that is the second switch group is also the same as that of the left switch section described above, and the description thereof is omitted.

  FIG. 3 is an operation mode state transition diagram of the left heating unit, and will be described below with reference to the drawings.

  When power is supplied to the device, the left heating unit shifts to the left initial mode, which is the first initial mode. In the left initial mode, the counter inside the control means is operated, and the inputs of the left heating off / on switch and the left timer switch are enabled.

  When the left heating off / on switch is accepted during the left initial mode, the left heating mode is turned on when the left heating unit is turned on. When the left timer switch is accepted, the mode is shifted to the left timer setting mode where the timer is set to limit the heating time. To do.

  In the left heating mode, the counter is cleared and stopped, the left heating operation is turned on, and heating display is performed on the left liquid crystal display device. During the left heating mode, the left heating off / on switch, left timer switch, left up switch, and left down switch inputs are enabled. When the left heating off / on switch is accepted, the mode shifts to the left initial mode. Is received, the left timer heating mode for performing the left heating operation for a limited time is entered, and when the left up switch and the left down switch are received, the heating output is increased or decreased while the left heating mode is maintained.

  In the left timer adjustment mode, the counter is operated and the set time is displayed on the left liquid crystal display device, and inputs of the left heating off / on switch, the left timer switch, and the left cancel switch are made valid. When the left heating off / on switch is accepted during the left timer adjustment mode, the mode shifts to the left timer heating mode. When the left cancel switch is accepted, the mode shifts to the left initial mode. When the left timer switch is received, the left timer alignment mode is maintained. Change the time.

  In the left timer heating mode, the counter is cleared and stopped, the left heating operation is turned on, and a limited time display and heating display are performed on the left liquid crystal display device. During the left timer heating mode, the left heating off / on switch, left timer switch, left up switch, left down switch, and left down switch inputs are enabled. When the left heating off / on switch is received, the left initial mode is entered. When the transition and left cancel switch are accepted, the mode is shifted to the left heating mode. When the left up switch and the left down switch are accepted, the heating output is increased or decreased while the left timer heating mode is maintained. When the left timer switch is received during the left timer heating mode, the set time is changed while the left timer heating mode is maintained.

  In the state transition described above, when the counter elapses for a predetermined time (here, 3 minutes), the device shifts to the left standby mode in which the operation of the left input switch is limited. The counter continues to operate during the left initial mode without heating and the left timer alignment mode, and clears and stops during the left heating mode and left timer alignment mode when heating is on. Counting and shifting to the standby mode in which the operation of the left input switch is restricted does not impair usability.

  In the left standby mode, the counter is cleared and stopped, and the left liquid crystal display device displays a standby state, and the left input switch is valid only for the left cancel switch and restricts the switch input operation. If the left cancel switch is input during the left standby mode, the mode shifts to the left initial mode and the standby state is released.

  In the left standby mode, input switch reception is limited to the left cancel switch as described above. The number of switches that can be input even if a user makes an incorrect input or a cooking utensil is placed on the switch. Since it is limited, unintended operation mode transition can be suppressed. Based on the detection principle of the capacitive touch switch, placing physical stress on highly conductive seasonings and water, spoons, knives, pans, highly conductive PET bottle seasonings, etc. will cause physical stress. Although there is a possibility that an input will be detected without being accompanied, the number of switch inputs that can be made in the left standby mode is limited, so that an unintended operation mode transition can be suppressed.

As described above, according to the present embodiment, when a predetermined time elapses in a state where there is no heating operation, the apparatus enters the standby mode by providing a standby mode that prohibits input except for a specific switch arranged on the top plate. In this case, it is possible to cancel the standby mode only with the switch on the top plate and to operate it by heating. Can be improved.

  Also, for example, even if the left cancel switch is received during the left standby mode, the transition destination is an initial mode that does not involve heating, so there is no possibility of performing a heating operation that is not intended by the user, thus improving safety. High consideration. Further, even after the transition to the unintended initial mode, the transition to the standby state is made again after 3 minutes, so that the erroneous input suppression effect can be maintained.

  Also, the left standby mode is easy to use because the release means can be done with a switch on the same surface as the top board, and the switch that performs the release operation also functions as another function (here, canceling the timer time setting) Therefore, there is no need to provide a dedicated switch, and the structure is inexpensive.

  FIG. 4 is an operation mode state transition diagram of the right heating unit, which has a right initial mode, a right timer adjustment mode, a right heating mode, a right timer heating mode, and a right standby mode, similarly to the left heating unit. The state transition by the right heating off / on switch, right down switch, right up switch, right timer switch, right cancel switch, and counter operation is the same, and the explanation of the operation is omitted.

  As shown in FIG. 3 and FIG. 4, by allowing the left heating unit and the right heating unit to independently hold the standby mode, it is possible to shift to the right standby mode during left heating, and also during left heating. Transition to the standby mode is possible, and the possibility of erroneous input of the input switch can be further suppressed.

  As described above, in the present embodiment, after considering the use conditions of normal heating and auto cooking, switching the switch detection time when heating is turned off, the convenience of providing a switch on the top plate, and auto The performance of cooking can be ensured at the same time.

  By providing a standby mode that prohibits input except for a specific switch placed on the top board after a predetermined time has passed without any heating operation or switch input, only the switch on the top board can be used even when the equipment enters standby mode. In addition to improving the usability by releasing the standby mode and improving the usability, it is possible to improve the effect of suppressing erroneous input of the switch input of the top plate arrangement by having the standby mode for each heating means.

  In this embodiment, the operation switch unit such as the first switch and the second switch and the liquid crystal display device are related to the heating of the object to be heated placed on the left side of the main body, and the object placed on the center of the main body. It is individually and independently related to the heating of the heated object and to the heating of the object to be heated placed on the right side of the main body, so that the user can easily know the operating status of each heating means It is easy to use.

  In the present embodiment, since the operation switch section such as the first switch and the second switch and the liquid crystal display device are independently arranged in front of each heating means, the operation status of each heating means can be easily achieved. It is possible to let the user know and it is easy to use.

  In addition, the operation switches such as the first switch and the second switch of the present embodiment are capacitive touch switches, and the touch switch accepts the switch just by touching in principle, so it has excellent operational feeling and is easy to use. Is good.

  In the present embodiment, the display means is described as a liquid crystal display device, but the same effect can be obtained even with a light emitting element such as an LED or a backlight unit.

In the present embodiment, the specific switch that releases the standby mode and shifts to the initial mode has been described as only the cancel switch, but even if other switches or a plurality of switches are effective as the release means, It is useful from the viewpoint of ensuring safety without shifting to the heating operation by one erroneous input.

  In addition, as shown in FIG. 7, even in a heating cooker having a configuration in which the heating unit according to the present embodiment has three units instead of two units, a stand-by mode independent from the left middle right is maintained, so that It is possible to improve the effect of suppressing erroneous input of the switch input of the plate arrangement.

  In addition, although the input switch has been described as a capacitive touch switch, even if a part or all of the input switch is a switch that converts physical stress into an electrical signal, the device is in a standby mode. In this case, it is possible to release the standby mode only with the switch on the top plate and to start heating operation. In addition to improving the usability, the heating mode has a standby mode for each heating means to suppress erroneous input of switch inputs on the top plate. Can be improved.

(Embodiment 2)
FIG. 5 is an operation mode state transition diagram of the left heating unit in the second embodiment of the present invention.

  In this embodiment, the state transition operation excluding the configuration diagram, the switch configuration diagram, and the timer count operation is the same as that of the first embodiment, and the description thereof is omitted. When power is supplied to the device, the left heating unit shifts to the left initial mode, which is the first initial mode, and after the counter is cleared at the mode shift, the counter operation is performed again. Initial mode with left cancel switch input during left standby mode, left heating off / on switch input during left heating mode, left cancel switch input during left timer alignment mode, left heating off / on switch input during left timer heating mode When shifting to, once the timer is cleared, the timer is restarted.

  Even when the left timer switch is input during the left initial mode and the mode shifts to the left timer alignment mode, the counter operation is performed again after the counter is cleared at the time of mode transition. In the left heating mode, the left timer heating mode, and the left standby mode, the counter is stopped after being cleared, as in the first embodiment.

  FIG. 6 is an operation mode state transition diagram of the right heating unit, which has a right initial mode, a right timer adjustment mode, a right heating mode, a right timer heating mode, and a right standby mode, similarly to the left heating unit. The state transition by the right heating off / on switch, right down switch, right up switch, right timer switch, right cancel switch, and counter operation is the same, and the explanation of the operation is omitted.

  As described above, in this embodiment, the counting operation is performed in the non-heating state, and once the switch is input, the timer is cleared once, so that there is no heating and no input operation for a predetermined time (here 3 minutes), the standby mode for restricting the operation of the input switch can be entered. By adding the input signal of the input switch to the standby mode as well as the heating state, it is easy to use so that the device does not shift to the standby mode during operation with the user's intention to use. Become.

  Also, during standby mode, the input switch acceptance is limited to only the cancel switch. Even if a user makes an incorrect input or a cooking utensil is placed on the switch, the number of switches that can be input is limited. Therefore, unintended operation mode transition can be suppressed. Based on the detection principle of the capacitive touch switch, placing physical stress on highly conductive seasonings and water, spoons, knives, pans, highly conductive PET bottle seasonings, etc. will cause physical stress. Although there is a possibility that an input will be detected even if it is not accompanied, since the number of switch inputs that can be performed in the standby mode is limited, unintended operation mode transition can be suppressed.

For example, even if a cancel switch is received during the standby mode, the transition destination is an initial mode that does not involve heating, so there is no possibility of performing a heating operation not intended by the user, and there is no concern for safety. high. In addition, even after the transition to the unintended initial mode described above, the transition to the standby state occurs again after 3 minutes, so that the erroneous input suppression effect can be maintained.

  In addition, the standby mode is easy to use because the release means can be operated by a switch on the same surface as the top board, and the switch for performing the release operation is also used for other functions (here, canceling the timer time setting). Therefore, there is no need to provide a dedicated switch, and the configuration is inexpensive.

  As shown in FIG. 5 and FIG. 6, by allowing the left heating unit and the right heating unit to independently hold the standby mode, it is possible to shift to the right standby mode during left heating, and also during left heating. Transition to the standby mode is possible, and the possibility of erroneous input of the input switch can be further suppressed.

  In this embodiment, the operation switch unit such as the first switch and the second switch and the liquid crystal display device are related to the heating of the object to be heated placed on the left side of the main body, and the object placed on the center of the main body. It is individually and independently related to the heating of the heated object and to the heating of the object to be heated placed on the right side of the main body, so that the user can easily know the operating status of each heating means It is easy to use.

  In the present embodiment, since the operation switch section such as the first switch and the second switch and the liquid crystal display device are independently arranged in front of each heating means, the operation status of each heating means can be easily achieved. It is possible to let the user know and it is easy to use.

  In addition, the operation switches such as the first switch and the second switch of the present embodiment are capacitive touch switches, and the touch switch accepts the switch just by touching in principle, so it has excellent operational feeling and is easy to use. Is good.

  In the present embodiment, the display means is described as a liquid crystal display device, but the same effect can be obtained even with a light emitting element such as an LED or a backlight unit.

  In the present embodiment, the specific switch that releases the standby mode and shifts to the initial mode has been described as only the cancel switch, but even if other switches or a plurality of switches are effective as the release means, It is useful from the viewpoint of ensuring safety without shifting to the heating operation by one erroneous input. In addition, as shown in FIG. 7, in the heating cooker having the configuration in which the heating unit according to the present embodiment has three ports instead of two, similarly, the first third corresponding to the left middle right heating coil. By causing the second switch group to maintain independent standby modes, it is possible to improve the erroneous input suppression effect of the switch input of the top panel arrangement.

  In addition, although the input switch has been described as a capacitive touch switch, even if a part or all of the input switch is a switch that converts physical stress into an electrical signal, the device is in a standby mode. In this case, it is possible to release the standby mode only with the switch on the top plate and to start heating operation. In addition to improving the usability, the heating mode has a standby mode for each heating means to suppress erroneous input of switch inputs on the top plate. Can be improved.

  As described above, the heating cooker according to the present invention can be used for heating operation by releasing the standby mode only with the switch on the top plate even when the device is in the standby mode. By having a standby mode for each means, the effect of suppressing erroneous input of the switch input of the top plate arrangement can be improved, so that it can be applied not only to electric heating and induction heating but also to uses such as a gas cooking device.
