Description

  The present invention relates to a cooking device such as a gas stove having a plurality of stove heat sources.

  Conventionally, as this type of heating cooker, a temperature sensor that detects the temperature of an object to be heated that is heated by one specific heat source of a plurality of stove heat sources is provided, and the specific heat source is controlled by a control unit that includes a timer. It is known that control is possible in a plurality of modes including a temperature control mode based on a temperature detected by a temperature sensor and a temperature timer combined control mode based on a temperature detected by the temperature sensor and a timer (for example, Patent Documents) 1). Here, a typical temperature control mode is a frying mode that controls the heat source so that the oil temperature is maintained at a set temperature, and a rice cooking mode that controls the amount of heating according to the temperature during rice cooking. Also, a representative example of the temperature timer combined control mode is a hot water mode in which the heat source is kept warm for a predetermined time after boiling and the operation of the heat source is stopped. Further, control in the timer mode based on the timer, that is, control for stopping the operation of the heat source after a predetermined set time has elapsed can be performed.

Here, in the conventional example, only the specific heat source can be controlled in the timer mode among the heat sources for the stove, but if the control in the timer mode for all the stove heat sources becomes possible, the usability is improved. In the above-mentioned Patent Document 1, the control means includes a timer for the grill in addition to the timer for the specific heat source so that the grill timer can control the grill heat source in the timer mode. Yes. Using this technique, it is conceivable to incorporate a timer for the stove heat source other than the specific heat source in the control means, and to control the corresponding stove heat source in the timer mode by each timer. However, this increases the number of timers built in the control means, complicating the control and increasing the cost.
JP-A-11-294777 (0037-0044, FIG. 3)

  In view of the above, the present invention makes it possible to control all the stove heat sources in the timer mode using a timer used for control in the temperature timer combined control mode of the specific heat source, and is easy to use at low cost. The problem is to provide a cooking device.

  In order to solve the above-described problems, the present invention includes a plurality of stove heat sources, a temperature sensor that detects the temperature of an object to be heated that is heated by one specific heat source of the stove heat sources, and a timer. A cooking device comprising: a control means capable of controlling the specific heat source in a plurality of modes including a temperature control mode based on the temperature detected by the temperature sensor and a temperature timer combined control mode based on the temperature detected by the temperature sensor and a timer. The control means is configured to be able to control any one of the plurality of stove heat sources in a timer mode based on the timer, and includes all the stove heat sources including the specific heat source in use. A heat source selecting means for selecting one of the stove heat sources and controlling the selected stove heat source in the timer mode by the control means. , During control of the temperature timer combination control mode for a specific heat source, characterized in that it is configured to also be unselectable any stove heat source other than the at least a specific heat source.

  ADVANTAGE OF THE INVENTION According to this invention, control in a timer mode can be performed with respect to the heat source for stoves selected by the heat source selection means using the timer used for control in the temperature timer combined use control mode of a specific heat source. Here, the stove heat source selected by the heat source selecting means is one of all the stove heat sources including the specific heat source in use. As a result, even if the control means does not include a plurality of timers, Control in the timer mode can be selectively performed with respect to the heat source for the stove (including the specific heat source), and an easy-to-use heating cooker can be obtained at low cost.

  However, if the timer is used for the control in the timer mode while the control is performed in the temperature timer combined control mode for the specific heat source, the temperature timer combined control cannot be executed. In the present invention, at the time of control in the temperature timer combined control mode of the specific heat source, at least any of the stove heat sources other than the specific heat source is not selected as the control target of the timer mode, thereby preventing the temperature timer combined control from being disabled. it can. In order to prevent the control mode of the specific heat source from being accidentally changed to the timer mode during control in the temperature timer combined control mode of the specific heat source, select the heat source during control in the temperature timer combined control mode of the specific heat source. You may make it impossible to select all the stove heat sources including the specific heat source by means. On the other hand, when it is desired that the control mode of the specific heat source can be changed from the temperature timer combined control mode to the timer mode, when the specific heat source is controlled in the temperature timer combined control mode, the heat source selection means other than the specific heat source is used. It is only necessary to disable the selection of the stove heat source.

  By the way, a timer is not used when controlling the specific heat source in the temperature control mode. Therefore, when controlling the specific heat source in the temperature control mode, if the heat source selection means is configured so that only the stove heat source other than the specific heat source can be selected, when the specific heat source is controlled in the temperature control mode, The stove heat source can be selected and controlled in the timer mode, and the timer can be fully utilized to improve usability as much as possible.

  Further, when the stove heat source other than the specific heat source is selected by the heat source selection means, it is desirable that the control of the specific heat source in the temperature timer combined control mode is prohibited. According to this, it is possible to prevent the control in the timer mode of the stove heat source other than the specific heat source from being disabled by the control in the temperature timer combined control mode for the specific heat source. In order to prevent the control mode of the specific heat source from being erroneously changed to the temperature timer combined mode when controlling the specific heat source in the timer mode, the temperature timer of the specific heat source is also controlled during the control of the specific heat source in the timer mode. Control in the combined control mode may be prohibited. On the other hand, when it is desired that the control mode of the specific heat source can be changed from the timer mode to the temperature timer combined control mode, when the specific heat source is selected by the heat source selection means, the temperature timer of the specific heat source is combined. Control in the control mode may be allowed.

  FIG. 1 shows a drop-in cooking device incorporated in a counter top (not shown) of a system kitchen. The cooker body 1 of the heating cooker is provided with three stove burners 2, 3, 4 and a grill 5 on the right side, the left side, and the rear side, which are heat sources for the stove. Then, on the top plate 6 that covers the cooker main body 1 from above, three burner openings for opening the stove burners 2, 3, and 4 are opened, and each burner opening is surrounded on the top plate 6. Each of the five virtues 7 is arranged so that an object to be heated such as a pan placed on each of the five virtues 7 can be heated by each of the stove burners 2, 3, 4. The right stove burner 2 is composed of an external flame type burner that forms an outward flame, and a temperature sensor 8 that detects the temperature of the heated object in contact with the bottom surface of the heated object in its inner circumferential space. Is provided. Further, the left stove burner 3 and the rear stove burner 4 are constituted by annular internal flame type burners that form an inward flame, and these burners 3 and 4 are not provided with temperature sensors.

  On the front surface of the cooker body 1, a central grill door 5a, a front panel 1a on the right side of the grill door 5a, and a front panel 1b on the left side of the grill door 5a are provided. A fire extinguisher button 51 and a fire power adjustment lever 52 for the grill 5 and a fire extinguishing button 21 and a fire power adjustment lever 22 for the right stove burner 2 are arranged on the lower and upper parts of the right front panel 1a. At the lower part and the upper part, a point-extinguishing button 31 and a thermal power adjusting lever 32 for the left stove burner 3 and a point-extinguishing button 41 and a thermal power adjusting lever 42 for the rear stove burner 4 are arranged. Further, the right front panel 1a is provided with an operation panel unit 9 on which switches for selecting various modes to be described in detail later are arranged.

  Referring to FIG. 2, each of the burner burners 2, 3, 4 and the grill burner 5 b provided on the grill 5 has electromagnetic valves 23, 33, 43, 53 controlled by a controller 10 composed of a microcomputer as control means. Then, gas is supplied through the gas amount adjusting valves 24, 34, 44, 54 operated by the heating power adjusting levers 22, 32, 42, 52. Here, each point fire extinguishing button 21, 31, 41, 51 can be pushed from the projecting position (fire extinguishing position) to the pushing position (ignition position). The mechanism is locked at the combustion position between the ignition position and the fire extinguishing position, and when it is pushed again from the combustion position, the locking at the combustion position is released and the fire extinguishing position is restored. And the signal from detectors (not shown), such as a limit switch which detects the position of the point fire extinguishing button 21, 31, 41, 51, is inputted into the controller 10. When each point-extinguishing button 21, 31, 41, 51 is pushed into the ignition position, the corresponding burner solenoid valve 23 via a push rod (not shown) linked to the point-extinguishing button 21, 31, 41, 51. , 33, 43, 53 are forcibly opened, and an igniter (not shown) is operated by the controller 10, and the corresponding burner is ignited by a spark discharge at a spark plug (not shown) attached to each burner. The After ignition, the controller 10 monitors the output of each of the thermocouples 25, 35, 45, 55 for flame detection attached to each of the burners 2, 3, 4, 5, and each thermocouple 25, 35, 45, When the output of 55 falls below a predetermined threshold value, the corresponding burner solenoid valves 23, 33, 43, 53 are closed to prevent the release of raw gas. When the point fire extinguishing buttons 21, 31, 41, 51 are returned to the fire extinguishing position, the controller 10 closes the corresponding solenoid valves 23, 33, 43, 53 of the burner to extinguish the burner. A bypass solenoid valve 26 for automatically adjusting the heating power is provided in the gas supply path for the right stove burner 2.

  The controller 10 includes a timer 10a. Then, the controller 10 controls the right control burner 2 provided with the temperature sensor 8 in a temperature control mode based on the temperature detected by the temperature sensor 8, a temperature timer combined control mode based on the temperature detected by the temperature sensor 8 and the timer 10a, a timer The control in the timer mode based on 10a can be selectively executed. As shown in FIG. 3, the operation panel 9 has a deep-fried food switch 91 for selecting a deep-fried food mode, which is one of the temperature control modes, and a rice-cooking switch 92 for selecting a rice cooking mode, which is another temperature control mode. And a water heater switch 93 for selecting the temperature timer combined control mode, a timer switch 94 for selecting the timer mode, an up / down switch 95 for changing the remaining time of the timer 10a, and the remaining time of the timer 10a. A display unit 96 is provided.

  The fried food mode is a mode in which the bypass solenoid valve 26 is opened and closed to control the heating power of the right stove burner 2 so that the temperature of the heated object detected by the temperature sensor 8 is maintained at a predetermined target temperature. . Each time the deep-fried food switch 91 is pressed, the target temperature is sequentially switched to 180 ° C., 200 ° C., and 160 ° C. When the deep-fried food switch 91 is further pressed, the selection of the deep-fried food mode is cancelled. In order to display the target temperature, LEDs 91a, 91b, 91c corresponding to temperatures of 200 ° C., 180 ° C., and 160 ° C. are provided, and the LEDs 91a, 91b, 91c corresponding to the switched target temperatures are turned on. The

  The rice cooking mode is a mode for controlling the heating power of the right burner 2 by opening and closing the bypass electromagnetic valve 26 so that the temperature of the heated object detected by the temperature sensor 8 matches a predetermined rice cooking control sequence. Then, each time the rice cooking switch 92 is pressed, the rice cooking control sequence is sequentially switched to the immediately-washed rice sequence, the rice-washing sequence, and the rice porridge sequence. When the rice cooking switch 92 is further pressed, the selection of the rice cooking mode is cancelled. Further, LEDs 92a, 92b and 92c corresponding to the respective sequences of rice porridge, rice washing immediately and every other rice washing are provided, and the LEDs 92a, 92b and 92c corresponding to the switched sequences are turned on.

  The hot water mode setting includes a heat retention setting and a fire extinguishing setting. In the heat retention setting, after the boiling of the object to be heated is detected from the temperature detected by the temperature sensor 8, the bypass solenoid valve 26 is closed to reduce the heating power of the right combustor 2 to a low level, and a specified time (for example, 5 minutes) from the boiling detection. Control is performed to extinguish the right combustor 2 after the elapse of time. In the fire extinguishing setting, control is performed to extinguish the right hob burner 2 after the elapse of a set time from the detection of boiling without causing low heat even if boiling is detected. Each time the hot water switch 93 is pressed, the setting of the hot water mode is switched in the order of the warming setting and the fire extinguishing setting. When the hot water switch 93 is further pressed, the selection of the hot water mode is canceled. Further, LEDs 93a and 93b corresponding to each setting of fire extinguishing and heat insulation are provided, and the LEDs 93a and 93b corresponding to the switched settings are turned on. When the fire extinguishing setting is selected, the set time is displayed on the display unit 96, and the set time can be changed by operating the up / down switch 95.

  The timer mode is a control mode in which the fire is extinguished when the remaining time of the timer 10a becomes zero, and the control in the timer mode can be performed not only for the right combustor 2 but also for the left combustor 3 and the rear conburner 4. To be able to Then, LEDs 94a, 94b, and 94c corresponding to the left and right conburners 4, 2, and 3 are provided, and the LEDs 94a, 94b, and 94c corresponding to the control burner selected as the control target in the timer mode are turned on. The remaining time of the timer 10a is displayed on the display unit 96, and the remaining time is changed by the up / down switch 95 so that the control burner to be controlled in the timer mode can be burned for the required time. In this embodiment, LEDs 91a to 94c are provided beside numbers and characters representing the setting of temperature, etc. in each mode of fried food, cooked rice, hot water, and timer, but the numbers and characters are formed as a watermark, You may arrange | position LED on the back surface.

  By the way, when the control in the timer mode is performed on the left and second rear burners 3 and 4 during the control of the right hot burner 2 in the hot water warming mode, the timer 10a cannot be used for the hot water warming mode control of the right hot burner 2. Further, when the control in the hot water mode is performed on the right conburner 2 during the control of the left conburner 3 and the rear conburner 4 in the timer mode, the timer 10a is switched to the timer mode control of the left conburner 3 and the rear conburner 4. Unusable. Therefore, in the present embodiment, selection of a control burner to be controlled in the timer mode and selection of the control mode of the right control burner 2 can be appropriately performed with correlation.

  Details of the control mode selection processing of the control burner and the right control burner 2 to be controlled in the timer mode are as shown in FIG. In the selection process, first, in step S1 to S5, a process of discriminating a currently used combustor is performed. If it is determined in step S1 that all the right, left, and rear conburners 2, 3, and 4 are in use (combustion), the left conburner 3 or It is determined whether or not the rear burner 4 is selected. If the left control burner 3 or the rear control burner 4 is not selected as the timer mode control object, it is determined whether or not any of the fried food switch 91, the rice cooking switch 92, and the hot water switch 93 is pressed in step S102. If it has been pressed, the process proceeds to step S103 to select a mode corresponding to the pressed switch as the control mode of the right burner 2, and control is performed in this mode. On the other hand, when the left conburner 3 or the rear conburner 4 is selected as the control object in the timer mode, after determining whether the fried food switch 91 or the rice cooking switch 92 is pressed in step S104 , The process proceeds to step S103.

  Therefore, when the left conburner 3 or the rear conburner 4 is selected as the control target of the timer mode, even if the hot water switch 93 is pressed, it is ignored, and the hot water mode is selected as the control mode of the right conburner 2. Absent. Therefore, it is possible to prevent the timer 10a from being used for the control in the hot water mode, and the control in the timer mode of the left stove burner 3 or the rear stove burner 4 from being disabled. When the right cooker 2 is selected as the timer mode control target, the control mode of the right cooker 2 is switched to the hot water mode when the hot water switch 93 is pressed. The reason for this is that even if control in the timer mode becomes impossible, there is no particular problem because the control mode is switched by the right-handed combustor 2 that is the same target. This is because it is easier to use.

  When the selection process of the control mode of the right stove burner 2 is performed as described above, the process proceeds to step S105, and whether a mode other than the frying mode, the rice cooking mode, and the hot water mode is selected as the control mode of the right stove burner 2 That is, it is determined whether the timer mode is selected or no mode is selected. When a mode other than the fried food mode, the rice cooking mode, and the hot water mode is selected, it is determined in step S106 whether any of the combustors is selected as the control target of the timer mode. If there is no control burner selected as the timer mode control target, when it is determined in step S107 that the timer switch 94 has been pressed, the right control burner 2 is selected as the timer mode control target in step S108. Then, the control in the timer mode is executed for the right burner 2. If there is a control burner selected as the timer mode control target, it is determined in step S109 whether the timer mode control target is the right control burner 2 or not. If the control object in the timer mode is the right control burner 2, when it is determined in step S110 that the timer switch 94 has been pressed, the left control burner 3 is selected as the control object in the timer mode in step S111. The control in the timer mode is executed for the burner 3. On the other hand, if the control object in the timer mode is not the right control burner 2, it is determined in step S112 whether or not the control object in the timer mode is the left control burner 3. If the control object in the timer mode is the left control burner 3, when it is determined in step S113 that the timer switch 94 has been pressed, the rear control burner 4 is selected as the control object in the timer mode in step S114. The control in the timer mode is executed for the burner 4. If the control object in the timer mode is not the left control burner 3, that is, if the control object in the timer mode is the rear control burner 4, when it is determined in step S115 that the timer switch 94 has been pressed, step S116 is performed. Thus, the timer mode is canceled, and no control in the timer mode is performed for any of the burners.

  Therefore, when a mode other than the deep-fried food mode, the rice cooking mode, or the hot water mode is selected as the control mode of the right burner 2, each time the timer switch 94 is pressed, the right control burner 2 is sequentially controlled as the timer mode control target. When the left conburner 3 and the rear conburner 4 are selected and the timer switch 94 is further pressed, the timer mode is canceled. When the control burner to be controlled in the timer mode is switched, the remaining time of the timer 10a becomes zero, and the remaining time of the timer 10a is changed during a predetermined time (for example, 15 seconds) from the switching time. If the timer is not performed, the timer mode is cancelled, and the burner that has been switched to the timer mode control target is extinguished in a certain time after a predetermined time has elapsed.

  When any one of the fried food mode, the rice cooking mode, and the hot water mode is selected as the control mode of the right stove burner 2, the fried food mode or the rice cooking mode is selected as the control mode of the right stove burner 2 in step S117. It is determined whether or not. If the fried food mode or the rice cooking mode is selected, it is determined in step S118 whether any one of the burners is selected as the control target of the timer mode. If there is no control burner selected as the control target in the timer mode, when it is determined in step S119 that the timer switch 94 has been pressed, the left control burner 3 is selected as the control target in the timer mode in step S120. Then, the control in the timer mode is executed for the left stove burner 3. If there is a control burner selected as the timer mode control target, it is determined in step S121 whether the timer mode control target is the left control burner 3 or not. If the control object in the timer mode is the left control burner 3, when it is determined in step S122 that the timer switch 94 has been pressed, the rear control burner 4 is selected as the control object in the timer mode in step S123. The control in the timer mode is executed for the burner 3. If the timer mode control target is not the left control burner 3, that is, if the timer mode control target is the rear control burner 4, when it is determined in step S124 that the timer switch 94 has been pressed, the process proceeds to S125. Cancel the timer mode in step.

  Therefore, when the fried food mode or the rice cooking mode is selected as the control mode of the right stove burner 2, every time the timer switch 94 is pressed, the control target of the timer mode is switched in the order of the left stove burner 3 and the rear stove burner 4. When the timer switch 94 is further pressed, the timer mode is canceled. And the right stove burner 2 is not selected as a control object of the timer mode, and it is prevented that the fried food mode or the rice cooking mode cannot be executed. Further, when “NO” is determined in the step S117, that is, when the control in the hot water pouring mode is being performed by the right stove burner 2, the operation of the timer switch 94 is ignored, and any of the combustors is not operated. However, the control in the timer mode cannot be executed. If there is no problem to the left even if the control mode of the right burner 2 can be switched from the hot water spray mode to the timer mode, the timer mode 94 can be controlled by operating the timer switch 94 when the right control burner 2 is controlled in the hot water warmer mode. As an alternative, it is possible to select only the right burner 2.

  In the case where one burner of the left burner 3 and the rear burner 4 is used in addition to the right burner 2, the process proceeds from the step S2 to the steps after S201 shown in FIG. The processing in the steps after S201 is substantially the same as the processing in the steps after S101 in FIG. 4 described above. For the steps similar to those in FIG. 4, the last two digits attached thereto are shown in FIG. This is the same as the last two digits of the step, and detailed description thereof is omitted. The difference between the selection process shown in FIG. 5 and the process shown in FIG. 4 is that the processes corresponding to steps S112 to S114 and steps S121 to S123 in FIG. 4 are not performed, and S211 corresponding to S111 and S120. The point is that one of the left burner 3 and the rear burner 4 in use is selected in step S220.

  Therefore, when a mode other than the deep-fried food mode, the rice cooking mode, and the hot water mode is selected as the control mode of the right stove burner 2, every time the timer switch 94 is pressed, the right control burner 2 is used as the control object of the timer mode. When the middle left burner 3 or the rear burner 4 is sequentially selected and the timer switch 94 is further pressed, the timer mode is canceled. In addition, when the fried food mode or the rice cooking mode is selected as the control mode of the right stove burner 2, when the timer switch 94 is pressed, the left stove burner 3 or the rear stove burner 4 being used as the control target of the timer mode is displayed. When selected and the timer switch 94 is further pressed, the timer mode is canceled. When the right hot-burner 2 is controlled in the hot water mode, the operation of the timer switch 94 is ignored, and the control in the timer mode cannot be performed for any of the hot-burners.

  When two burners, the left stove burner 3 and the rear stove burner 4, are used, the process proceeds from step S3 to step S301 and subsequent steps shown in FIG. In step S301, it is determined whether or not any combo burner is selected as a control object in the timer mode. If there is no control burner selected as the control object in the timer mode, the left control burner 3 is selected as the control object in the timer mode in step S303 when it is determined in step S302 that the timer switch 94 has been pressed. Then, the control in the timer mode is executed for the left stove burner 3. If there is a control burner selected as the timer mode control target, it is determined in step S304 whether the timer mode control target is the left control burner 3 or not. If the control object in the timer mode is the left control burner 3, when it is determined in step S305 that the timer switch 94 has been pressed, the rear control burner 4 is selected as the control object in the timer mode in step S306. The control in the timer mode is executed for the burner 4. If the control object in the timer mode is not the left control burner 3, that is, if the control object in the timer mode is the rear control burner 4, when it is determined in step S307 that the timer switch 94 has been pressed, step S308 is performed. To cancel the timer mode.

  Therefore, when using the two burners of the left and second burners 3 and 4, the left and third burners 3 and 4 are sequentially controlled as timer mode control targets each time the timer switch 94 is pressed. When selected and the timer switch 94 is further pressed, the timer mode is canceled.

  If only the right burner 2 is used, the process proceeds from step S4 to step S401 and subsequent steps shown in FIG. 7. In step S401, any one of the deep-fried food switch 91, the rice cooking switch 92, and the hot water switch 93 is pressed. If it has been pressed, the process proceeds to step S402 to select a mode corresponding to the pressed switch as the control mode of the right burner 2, and control is performed in this mode. Next, it progresses to the step of S403 and it is discriminate | determined whether modes other than the fried food mode, the rice cooking mode, and the hot water mode are selected as a control mode of the right stove burner 2. FIG. When a mode other than the deep-fried food mode, the rice cooking mode, and the hot water mode is selected, it is determined in step S404 whether or not any of the combo burners is selected as the control target of the timer mode. If there is no control burner selected as the timer mode control target, when it is determined in step S405 that the timer switch 94 is pressed, the right control burner 2 is selected as the timer mode control target in step S406. Then, the control in the timer mode is executed for the right burner 2. If there is a control burner selected as the timer mode control target, that is, if the right control burner 2 has already been selected as the timer mode control target, it is determined that the timer switch 94 has been pressed in step S407. The timer mode is canceled in step S408.

  Therefore, when only the right stove burner 2 is used, the corresponding control mode is selected by pressing the deep-fried food switch 91, the rice cooking switch 92, and the hot water switch 93. Moreover, when control in each control mode of fried food, rice cooking, and hot water is not performed, control in timer mode is performed by pushing the timer switch 94.

  When only one burner of the left stove burner 3 and the rear stove burner 4 is used, the process proceeds from step S5 to step S501 and subsequent steps shown in FIG. In step S501, it is determined whether or not any combo burner is selected as a control object in the timer mode. If there is no control burner selected as the control target in the timer mode, it is determined in step S502 that the timer switch 94 has been pressed, and the left control burner 3 and the rear control burner 4 are selected in step S503. One burner in use is selected as a control object in the timer mode, and the control in the timer mode is executed for the one burner. If there is a control burner selected as the timer mode control target, that is, if one of the burners has already been selected as the timer mode control target, it is determined in step S504 that the timer switch 94 has been pressed. The timer mode is canceled in step S505.

  Therefore, when only one burner of the left burner 3 and the rear burner 4 is used, each time the timer switch 94 is pressed, the control of the one burner in the timer mode and the release thereof are performed. .

  As described above, in this embodiment, the timer switch 94 and the control burner to be controlled in the timer mode by the processing in steps S105 to S125, S205 to S225, S301 to S308, S403 to S408, and S501 to S505 are provided. The burner selection means (heat source selection means) to be selected is configured. During the control of the right hot burner 2 in the hot water washing mode, any of the hot burners 2, 3 and 4 that are being used as control objects in the timer mode cannot be selected, and the hot water warming mode of the right hot burner 2 (temperature timer combined control) is disabled. It is possible to prevent the control in the mode) from being disabled.
