Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oven cooking apparatus for baking food such as bread dough.

Patent Literature 1 discloses a deck oven (oven cooking apparatus) for baking bread dough. This type of deck oven has a preheating function that raises the temperature inside the furnace to a set temperature suitable for baking as a step before using the furnace. Some even have a scheduling feature that automatically starts on time. Deck ovens are often used for business purposes, so in daily work such as bakeries, the reservation function is used to set the temperature inside the oven to the appropriate temperature for baking at the timing when the bread dough to be baked first of the day is ready. be.

A deck oven with a reservation function is generally configured so that a user inputs a time to start preheating, and preheating starts when the current time coincides with the start time. This makes it possible, for example, to start preheating at 6 o'clock every morning. In addition, there is also a configuration in which the number of days to wait until the next business day (waiting days) and the start time of preheating on the next business day can be entered in consideration of the store's closed days. As a result, it is possible to make a reservation for preheating of the deck oven for the next business day on the day before the holiday, with several holidays (waiting days) in between.

Japanese Patent Application Laid-Open No. 2004-267104

Of the above-mentioned deck ovens with a reservation function, for those in which the number of days off work (waiting days) is entered, the timing of setting the reservation for preheating and the start time of preheating on the next business day task to be attempted] column), there is a risk that the number of waiting days may be counted incorrectly.

When configuring the reservation function to start preheating when the current time coincides with the reserved time, for example, instead of calculating the remaining time including the number of standby days by converting the number of standby days into hours, The algorithm is simpler to find the number of remaining days by subtracting one day when the reserved time is reached. Therefore, for example, if the preheating reservation is set at 7:00 a.m. on the day before the holiday and the reservation time is 6:00 a.m. on the next business day, the first day will be 23 hours from the reservation setting. It is decremented after the hour (6 o'clock the next day). On the other hand, for example, if the preheating reservation is set at 5:00 a.m. on the day before the holiday and the reservation time is 6:00 a.m. on the next business day, the reservation for the first day will be 1 hour later (6 o'clock on the day).

In other words, if the reservation function is configured to start preheating when the current time coincides with the reserved time, the timing of the reservation setting may differ from the reserved time (only the time, ignoring the date). ), the date on which preheating is started is changed, which may lead to a problem of incorrect setting. SUMMARY OF THE INVENTION It is an object of the present invention to provide an oven cooking apparatus in which erroneous settings are less likely to occur in the reservation function.

In order to solve the above problems, the present invention provides a baking furnace for baking an object to be cooked, a heater arranged so as to be able to heat the inside of the baking furnace, a control unit for controlling heating of the heater, and a start of heating. A reservation unit that allows the user to set the timing using month/day information and time information, and a clock unit that outputs the current month/day information and time information to the control unit. Provided is an oven cooking apparatus characterized by starting heating of a heater when it is determined that the start timing has arrived based on date information and time information.

In the oven cooking apparatus configured as described above, the user can set the timing to start heating by using the date information and the time information by the reservation unit. Heating of the heater is started when it is determined that the start timing has arrived based on the date information and the time information. When using the reservation function, the user can directly set the heating start timing based on the month and day information and the time information, thereby making it difficult for erroneous settings to occur in the reservation function. For example, it is difficult to make a mistake even if you make a reservation for the next day or later.

In the oven cooking apparatus configured as described above, the reservation unit allows the user to set the end timing of heating using time information. Based on this, it is preferable to terminate the heating of the heater when it is determined that the end timing for the month and day of the start timing has arrived. When configured in this way, in addition to the start timing of heating, the end timing of heating can also be set in advance. Therefore, even if the user forgets to turn off the heating switch of the oven cooking apparatus at the end of business hours of the store, the reservation function can be used. By doing so, the heating can be automatically terminated.

In the oven cooking apparatus configured as described above, the reservation unit uses the (24+X) time system as the time information of the end timing when the time information indicates the time from midnight to the predetermined time X, Alternatively, it is preferable to receive the setting with the time information expressed in 12-hour format with the next day information added. When configured in this way, in the 24-hour system, the time from 0:00 to 6:00 after 24:00 can be expressed as, for example, "24:00 to 30:00", and the 12-hour system In , the time from 00:00 to 06:00 after 24:00 can be expressed as, for example, "00:00 the next day to 06:00 the next day". By representing the time information for setting the end timing of heating such as "24:00 to 30:00" or "00:00 to 06:00 on the following day", the time information can be displayed to the user on the next day. It is possible to clearly convey that it is time.

Further, in the oven cooking apparatus configured as described above, the reservation unit accepts setting of month and day information from the current date to predetermined N weeks exceeding one week as the start timing month and day information. is preferred. When configured in this way, for example, even when the store is closed continuously for more than one week (seven days) (for example, a long-term closure of two weeks), the user can start heating. Timing can be directly set by date information and time information, and a reservation function can be used.

(illustration omitted). In this embodiment, the controller 70 primarily controls the lower and upper heaters 41,42.

By configuring the hardware of the oven cooking apparatus 10 in this way, the controller of the operation panel 50 or the control device 70 executes the main control process by the main program shown in FIG. In this embodiment, a case where the controller of the operation panel 50 executes the main program will be described as an example. This main program is stored in the ROM of the controller. AC power is supplied to the oven cooking apparatus 10 from the outside, and even when the operation panel 50 is operated to turn off the power, driving power converted to DC is supplied to the operation panel 50 and the control device 70. (standby state).

[Main control process]
As shown in FIG. 8, when the controller of the operation panel 50 is started in the standby state, first, the work area and flags secured in the RAM are set to initial values by the initialization processing in step 10, and the power is turned off last time. In the off process (S21), each setting information related to manual operation stored is read from a non-volatile memory such as EEPROM. After that, the controller determines in step 11 whether there is an operation start input. The operation start input is, for example, information input by the user continuously pressing the operation on/off button 55 of the operation panel 50 for one second or longer. , the power switch and the like for supplying power to the lower heater 41 and the upper heater 42 are turned on by the power-on process of step 12 . After that, the normal operation process of step 13 is performed. This normal operation process (S100) will be described later with reference to FIGS. 9 to 15. FIG.

On the other hand, if there is no operation start input in step 11, the user has not yet operated the operation on/off button 55 of the operation panel 50, so the controller of the operation panel 50 determines "NO" and the reserved operation is performed in step 14. It is determined whether or not there is, that is, whether or not the operation reservation is set to "Yes". The reserved operation is an operation mode in which the oven cooking apparatus 10 performs a manual operation process (S200) described later at the preset operation start date and time and end time. S430), this is performed when the operation reservation is set to "Yes". If there is a reserved operation, after determining "YES" in step 14, it is further determined in step 15 whether or not the set reservation date and time has arrived. In the determination process of step 15, the current date and time information output from the clock function of the controller of the operation panel 50 is compared with the reservation date and time information. , and the process proceeds to the reserved operation process of step 16. This reserved operation process (S150) will be described later with reference to FIGS. 16 and 17. FIG.

If there is no reserved operation in step 14, or if the current date and time has not reached the reserved date and time in step 15, it is determined "NO" in these steps and the process proceeds to step 17. At step 17, it is determined whether or not there is an operation interlock. The operation interlocking is an operation mode in which the operation information is directly input to the oven cooking apparatus 10 from the operator and the operator can operate the oven cooking apparatus 10. can be set. If there is operation interlocking, after determining "YES" in step 17, it is further determined in step 18 whether there is an input of operation information from the operation (operation input). Then, if there is an up-down input, the determination is "YES", and the process moves to the up-down interlocking process of step 19 that follows. Note that the control is an example of an external device, and the control input is an example of an external input.

On the other hand, if there is no operation interlocking in step 17 or if there is no operation input in step 18, it is determined "NO" in these steps, and in step 20 it is determined that there is an operation end input. The operation end input is operation end information that is input when the operation end processing (S140, S153, S158) is performed in the normal operation processing (S100) or the reserved operation processing (S150), which will be described later. If there is (operation end information), after determining "YES", the power supply switch or the like for supplying power to the lower heater 41 and the upper heater 42 is turned off by the power-off processing of step 21 . Then, after each setting information (set temperature, timer time, etc.) related to the currently set manual operation is stored in a non-volatile memory such as EEPROM, the process returns to step 11 .

On the other hand, if there is no operation end input in step 20, the oven cooking apparatus 10 is not in operation (before operation is started), so it is determined "NO" and the process returns to step 11 to input operation start. It is determined whether or not there is That is, the controller of the operation panel 50 performs the above-described determination processes of steps 11, 14, and 17 until it shifts to any of the normal operation process of step 13, the reserved operation process of step 16, and the down control interlocking process of step 19. Repeat.

[Normal operation process]
Next, normal operation processing by the normal operation program will be described with reference to FIG. Incidentally, in this embodiment, the normal operation program is stored in the ROM of the controller of the operation panel 50. FIG. As shown in FIG. 9, the controller first displays the home menu on the display section 51 of the operation panel 50 at step 110 . As shown in FIG. 6, the home menu display screen 60aa includes, for example, a home icon 61, a manual operation bar 62, a program operation bar 63, an equipment setting bar 64, and an inspection bar 65. 12:34 displayed on the upper left of the display screen 60aa is the current time (12:34) displayed in the 24-hour system by the clock function of the controller.

The home icon 61 is a pictogram that visually and intuitively indicates to the user that the display screen 60aa is the home menu. The manual operation bar 62, the program operation bar 63, the device setting bar 64, and the inspection bar 65 are item bars that can be selected by the user by rotating the jog dial 58 of the operation panel 50 in the circumferential direction. A white frame is displayed around the selected item bar (the manual operation bar 62 is selected in FIG. 6). When the user presses the jog dial 58 in the axial direction, the item bar in the selected state is selected.

When the controller of the operation panel 50 determines that the manual operation bar 62 has been selected and determined by the user's operation of the jog dial 58 (S110; "manual operation"), the manual operation process of step 200 is performed. The manual operation process (S200) will be described later with reference to FIGS. When the manual operation process of step 200 ends, it is determined in the next step 120 whether or not the operation is off. . If the operation is turned off, the determination is "YES" and the process proceeds to operation end processing at step 140 . Operation off information is input when the user presses the operation on/off button 55 continuously for one second or more. Although not shown, if it is determined in step 120 that the home button 53 or return button 54 has been pressed by the user, the process returns to step 110 to display the home menu on the display unit 51 .

When the controller of the operation panel 50 determines that the program operation bar 63 has been selected and determined by the user's operation of the jog dial 58 (S110; "program operation"), the program operation process of step 300 is performed. While the manual operation process inherits the operating conditions such as the set temperature and timer time from the previous manual operation, in this program operation process (S300), multiple set temperatures and timer times preset by the user are performed. An arbitrary operating condition is selected from such as, and processing is performed based on it. In other words, the programmed operation process (S300) performs the same process as the manual operation process (S200), which will be described later, except that the user can select the operating conditions in advance. When the program operation process ends, it is determined in the next step 130 whether or not the operation is turned off. If the operation is not turned off, it is determined "NO", and the program operation process (S300) is performed again. If the operation is turned off, the determination is "YES" and the process proceeds to operation end processing at step 140 . Although not shown, if it is determined in step 130 that the home button 53 or return button 54 has been pressed by the user, the process returns to step 110 to display the home menu on the display unit 51 .

In the operation end processing (S140), an operation end input (operation end information) is output to the main control processing by the main program described above. When the operation end process (S140) ends, the normal operation process ends and the process returns to the main control process (FIG. 8) by the main program.

When the controller of the operation panel 50 determines that the device setting bar 64 has been selected and determined by the user's operation of the jog dial 58 (S110; "Device setting"), the process proceeds to step 400 for device setting processing. This device setting process (S400) will be described later with reference to FIG. At step 400, the device setting process is repeatedly executed until the home button 53 of the operation panel 50 is pressed, as will be described later.

When the controller of the operation panel 50 determines that the inspection bar 65 has been selected and determined by the user's operation of the jog dial 58 (S110; "inspection"), the inspection process of step 500 is performed. In this inspection process (S500), for example, a list of error information and notification information currently occurring in the oven cooking apparatus 10 is displayed on the display unit 51 as inspection items. The error information is, for example, abnormality information of the lower temperature sensor 43, the upper temperature sensor 44, the controller board, or the like. Further, the notification information includes detailed content of error information, a message prompting the user to contact a service company or the like, and the like. At step 500, the display screen for inspection processing is repeatedly executed until the home button 53 of the operation panel 50 is pressed.

[Manual operation processing]
Next, manual operation processing by the manual operation program will be described with reference to FIGS. 10 and 11. FIG. In this embodiment, the manual operation program is stored in the ROM of the controller of the operation panel 50. FIG.

As shown in FIG. 10, the controller of the operation panel 50 first sends instruction information (heating start information) to the control device 70 to start heating by the lower and upper heaters 41 and 42 by starting preheating in step 201. to send out. This heating start information includes each setting information (setting temperature, timer time, etc.) related to the previous manual operation stored in the non-volatile memory by the controller in the power-off process (S21 in FIG. 8). Each of these setting information is read from the non-volatile memory by the controller. The heating start information includes the heating power levels of the lower and upper heaters 41 and 42, the set temperature, the set time of the timer, and the like. The heating power level is a step display in which the output can be set discontinuously for each of the lower and upper heaters 41 and 42. In this embodiment, the ratio of the maximum output of the heater (0%, 20%, 40%, 60%, 80%, 100%) can be set in six levels from level 0 (0%) to level 5 (100%).

When receiving such heating start information, the control device 70 turns on the power switch that controls the power supply to the lower and upper heaters 41 and 42 to supply power corresponding to a preset heating power level to these heaters 41 . , 42 and start temperature control for the lower and upper heaters 41 , 42 . As a result, the temperature inside the firing furnace 20 begins to rise, so that the lower temperature information and the upper temperature information output from the lower temperature sensor 43 and the upper temperature sensor 44 by the upper and lower temperature detection in step 202 are sent to the controller 70. to get via. Then, the lower and upper temperature information and the like acquired in step 202 are output and displayed on the display section 51 of the operation panel 50 in step 203 .

At step 203, the controller of the operation panel 50 displays, for example, the display screen 60ma shown in FIG. On this display screen 60ma, as information immediately after the start of preheating, "preheating", "M manual operation", the current temperature of the upper heat (the upper part of the furnace) of 30 ° C., the set temperature of 200 ° C., and the thermal power level of 5, The current temperature of the bottom heat (the lower part of the furnace) of 30° C., the set temperature of 200° C., the thermal power level of 3, the timer time of 10 minutes and 00 seconds, etc. are displayed.

Then, in step 204, the controller of the operation panel 50 determines whether the temperature inside the firing furnace 20 has reached the set temperature. Since the firing furnace 20 of this embodiment is provided with the lower and upper heaters 41 and 42 in the furnace, the temperatures detected by the corresponding lower and upper temperature sensors 43 and 44, that is, the lower temperature and When all the upper temperatures are equal to or higher than the set temperature, the controller determines that the temperature inside the firing furnace 20 has reached the set temperature.

When both the lower temperature information and the upper temperature information output from the lower temperature sensor 43 and the upper temperature sensor 44 reach the respective set temperatures or higher and the controller determines "YES", the preheating ends. Therefore, in step 205, for example, the "standby" display screen 60mb shown in FIG. notify the user. On the other hand, if either the lower temperature information or the upper temperature information has not reached the set temperature or higher and the controller determines "NO", the process returns to step 202 again.

When the preheating is finished and the main heating is started, it is determined in step 206 whether there is an input from the start/stop button 56 . That is, since the temperature in the baking furnace 20 has reached the set temperature, the user opens the door 21 of the oven cooking apparatus 10 and carries a tray containing the food to be cooked such as bread dough into the baking furnace 20.例文帳に追加Then, when the door 21 is closed, the user presses the start/stop button 56 on the operation panel 50 in order to start a timer that measures a preset baking time (10 minutes and 00 seconds in the example of FIG. 11(c)). do.

If there is an input from the start/stop button 56 at step 206 and it is judged as "YES", the timer countdown is started and at the next step 207, for example, "cooking" shown in FIG. 11(c) is displayed. The display screen 60mc is displayed on the display unit 51 . In this example of the display screen 60mc, the lower temperature information, the upper temperature information, and the remaining time information are successively updated and displayed until the timer's remaining time of 9 minutes and 59 seconds reaches zero, that is, until the time expires (in S208, " NO").

Although not shown in FIG. 10, an algorithm may be configured so that the input determination of the start/stop button 56 can be performed even after the start of preheating and until the end of preheating. In this case, even before the temperature in the firing furnace 20 reaches the set temperature, when it is determined that there is an input from the start/stop button 56, the countdown of the timer is started and at step 207, for example, as shown in FIG. 11(c). The algorithm is configured so as to display the display screen 60mc showing "cooking" on the display unit 51 .

When the controller of the operation panel 50 determines "YES" in step 208 because the remaining time of the timer becomes zero, in step 209, the display screen 60md of "cooking completed" shown in FIG. , or the buzzer unit 19 is sounded with a predetermined beep to inform the user that the cooking has been completed. As a result, it is highly probable that the food to be cooked in the baking furnace 20 has been completely baked, so the user opens the door 21 of the oven cooking apparatus 10 and removes the tray containing the food to be cooked, such as baked bread. Take out from the firing furnace 20 .

Thereafter, the controller finishes this manual operation process and returns to the normal operation process (FIG. 9), determines "NO" if the operation is not turned off in step 120, and shifts to the manual operation process (S200) again. That is, when the user does not press the operation ON/OFF button 55 on the "cooking completed" display screen 60md, the manual operation process (S200) is executed again. As a result, when the temperature in the baking furnace 20 drops below the set temperature due to the opening and closing of the door 21 due to the unloading of the food to be cooked, etc., preheating is continued until the set temperature is reached after the start of preheating in step 201. Therefore (S202 to S204), the display screen 60ma is displayed on the display unit 51 (FIG. 11(a)), and when the set temperature is reached, the display screen 60mb is displayed (FIG. 11(b)).

[Device setting process]
Next, device setting processing by the device setting program will be described with reference to FIGS. 12 and 14. FIG. In this embodiment, the device setting program is stored in the ROM of the controller of the operation panel 50. FIG. As shown in FIG. 14A, when the device setting bar 64 is selected and determined by operating the jog dial 58 on the home menu display screen 60ab, as shown in FIG. to display the device setting menu on the display unit 51 of the operation panel 50 .

As shown in FIG. 14(b), on the display screen 60sa of the device setting menu, for example, on the first page, "interlocking control", "operation reservation", "steam time", "rapid preheating mode", "timer extension Setting items such as "time" are displayed. The second and subsequent pages are hidden at the bottom of the screen and are not shown, but by switching pages, "screen brightness", "buzzer volume", "end buzzer type", "end buzzer interval", "end buzzer length" , etc. are also displayed.

When the controller of the operation panel 50 determines that the item "down control interlock" has been selected and determined by the user's operation of the jog dial 58 (S401; "down control interlock"), the process proceeds to the down control interlock setting process of step 410. In this operation interlocking setting process (S410), it is set whether or not to operate the oven cooking apparatus 10 by the operation (in conjunction with operation) (not in operation).

When the controller of the operation panel 50 determines that the user has operated the jog dial 58 to select and confirm the item "operation reservation" (S401; "operation reservation"), the process proceeds to operation reservation setting processing in step 430. This operation reservation setting process (S430) will be described later with reference to FIGS. 13 to 15. FIG.

When the controller of the operation panel 50 determines that the item "steam time" has been selected and determined by the user operating the jog dial 58 (S401; "steam time"), the process proceeds to step 450 for setting the steam time. In this steam time setting process (S450), the time (steam time) for generating steam from the steam generator 47 when the user presses the steam button 52 on the operation panel 50 is set within the range of 1 to 5 seconds.

When the controller of the operation panel 50 determines that the item "rapid preheating mode" has been selected and determined by the user operating the jog dial 58 (S401; "rapid preheating mode"), the process proceeds to the rapid preheating mode setting process of step 470. Transition. In this rapid preheating mode setting process (S470), preheating is performed by setting the outputs of the lower and upper heaters 41 and 42 to the maximum during the initial (initial) preheating after the power of the oven cooking apparatus 10 is turned on (rapid preheating). Preheat mode) or not (no rapid preheat mode).

When the controller of the operation panel 50 determines that the item "timer extension time" has been selected and determined by the user operating the jog dial 58 (S401; "timer extension time"), the timer extension time setting process of step 490 is executed. Transition. In this timer extension time setting process (S490), the time for extending the timer time (timer extension time) when the user presses the timer extension button 57 of the operation panel 50 is set within a range of 10 seconds to 60 seconds.

Descriptions of the cases where items such as "screen brightness", "buzzer volume", "end buzzer type", "end buzzer interval", and "end buzzer length" are omitted will be omitted. When these setting processes (S410, S430, S450, S470, S490, etc.) are completed, the process returns to step 401, and the device setting menu display screen 60sa is displayed again. When the home button 53 is pressed, a home menu display screen 60ab is displayed.

[Operation reservation setting process]
Next, operation reservation setting processing by the operation reservation setting program will be described with reference to FIGS. 13 to 15. FIG. In this embodiment, the operation reservation setting program is stored in the ROM of the controller of the operation panel 50. FIG.

As shown in FIGS. 14(b) to 14(d), when the item "operation reservation" is selected and determined by operating the jog dial 58 in the device setting menu, the display of the display unit 51 changes to the display screen 60sa. A transition is made from the display screen 60sb to the display screen 60sc. After that, as shown in FIG. 13 , the controller of the operation panel 50 displays setting items for operation reservation on the display section 51 of the operation panel 50 in step 431 . As shown in FIG. 14(e), on the display screen 60ra of setting items for operation reservation, setting items such as "operation start date and time", "operation start time", "operation stop time", and "confirm" are displayed. These are selected and determined by operating the jog dial 58 . "Start date and time of operation" is information on the date and time of the start of heating. "Operation start time" is time information of the start timing of heating. "Operation off time" is time information of the end timing of heating.

When the controller determines that the user has operated the jog dial 58 to select and determine the item "Date of driving" (S432; "Date of driving"), the display screen 60ra as shown in FIG. is displayed, and step 433 enables the input of the date for starting the reserved operation (operation start date). If "-- / --" is displayed as the date, it means that the date is not set as the default value and is not entered. As shown in the display screen 60rb shown in FIG. 14(f), the date to be input can be selected by turning the jog dial 58 left or right (clockwise to advance the date after the operation date, counterclockwise to return the date to the range after the operation date). ) (S434; NO), and the date selected by the user is determined by pressing the jog dial 58 (S434; YES).

The dates that can be selected are, for example, 10 days or 20 days ahead from the operation date (current date) on which the user is performing the operation, or a predetermined N weeks exceeding one week (seven days) (for example, two weeks). 3 weeks) in the previous range. Thus, even when the store is scheduled to be closed for a long period of two weeks from the day after the operation day, the date of the next business day after the closed period can be selected and determined. Such date information is acquired from calendar information created based on the clock function (clock section) of the controller of operation panel 50 .

When the controller determines that the item "operation start time" has been selected and determined by the user's operation of the jog dial 58 (S432; "operation start time"), the display screen 60rc shown in FIG. is displayed, and step 435 enables the input of the time to start the reserved operation (operation start time). If "--:--" is displayed as the time, it means that the time has not been set as the default value and has not been input. The time to be input can be selected by turning the jog dial 58 left and right (clockwise to advance the time and counterclockwise to return the time) (S436; NO). (S436; YES). After the determination, the display returns to the display of the setting items, and the display screen 60rd as shown in FIG. 15(h) is displayed.

When the controller determines that the item "operation off time" has been selected and determined by the user's operation of the jog dial 58 (S432; "operation off time"), the item "operation on time" has been selected and determined. In the same way as in the case above, step 437 enables the input of the time to end the reserved operation (running-off time), and enables the selection and determination of the time using the jog dial 58 (S438). After the determination, the display returns to the display of the setting items and is displayed like the display screen 60re shown in FIG. 15(i).

In this embodiment, when the time is displayed in the 24-hour system, the operation start time and operation stop time can be input in the range of 00:00 to 23:59. It may be configured to allow input in the range of 00. That is, the time from 00:00 to 06:00 after 24:00 may be expressed as "24:00 to 30:00". In addition, when the time is displayed in the 12-hour system, the operation start time and operation stop time can be entered in the range from 00:00 am to 11:59 pm. It may be configured to allow input within the range of 06:00. That is, the time from 0:00 am to 6:00 am after 0:00 am may be expressed as, for example, "00:00 the next day to 06:00 the next day." This allows the user to intuitively and easily understand that the time information is the time of the next day. It should be noted that after 24:00, for example, it may be configured so that it can be input within a range such as 00:00 to 36:00 or 00:00 to 12:00 the next day.

Then, if at least the operation start date, the operation start time, or the operation stop time of the operation start date, the operation start time, and the operation stop time are input (S439; YES), The display screen 60rf as shown is displayed, and "OK" can be selected. That is, if either one of the driving-on information (driving-on date and driving-on time) or driving-off information (driving-off time) is input, it is possible to select "determine". As reserved operation, only the operation start date and time or only the operation end time can be set.

When the controller determines that the item "determination" is selected by the user operating the jog dial 58 (S432; "determination") and has been determined (S440; YES), the entered and determined reservation information is stepped. 441 saves (stores) in the non-volatile memory of the controller (S441). After that, after displaying the display screen 60rg as shown in FIG. 15(k) (S442), the process returns to the device setting process (S401 in FIG. 12) to display the device setting menu as shown in FIG. 15(m). Display the screen 60sd. This makes it possible to confirm that the operation reservation has been set to "Yes".

[Reserved operation processing]
Next, reserved operation processing by the reserved operation program will be described with reference to FIGS. 16 and 17. FIG. In this embodiment, the reserved operation program is stored in the ROM of the controller of the operation panel 50. FIG. In the reserved operation process, the normal operation process is not performed (S11; NO in FIG. 8), and the operation reservation is set to "Yes"(S14; YES ) and when the reserved date and time has arrived (S15; YES). In this embodiment, the two reserved operation processes S150a and S150b shown in FIGS. 16(a) and 16(b) are executed in parallel. The reserved operation is an operation mode in which the oven cooking apparatus 10 performs manual operation at a preset operation start date and time and end time. This is because it is necessary to end the manual driving process when the driving end time arrives while the manual driving process is being started.

First, the reserved operation process S150a in FIG. 16(a) will be described. The controller of the operation panel 50 first performs processing for starting manual operation in step 151 . Manual operation is thereby started. Since the details of the manual operation have already been explained with reference to FIGS. 10 and 11, they are omitted here. The manual operation process at step 151 is repeated until the user presses the operation on/off button 55 continuously for one second or more to input information to turn off the operation (S152; NO). When the information is input (S152; YES), the operation end processing (S153) is performed, and then the reserved operation processing S150a is finished and the main control processing (FIG. 8) is returned to. In the operation end process (S153), an operation end input (operation end information) is output to the above-described main control process.

On the other hand, in the reserved operation process S150b of FIG. 16(b), the controller of the operation panel 50 first calculates the remaining time until the shutdown time in step 154, and then checks whether the remaining time is 3 minutes. judge. If the remaining time is 3 minutes, the determination is YES, and the display screen 60rx shown in FIG. On this display screen 60rx, as information of "notice", it is displayed that the reserved operation has been shifted to the "operation reservation setting", and that "3 minutes and 00 seconds remain until the operation is turned off" due to the reserved operation. is displayed. Also displayed is a button (the default is "No") for selecting whether or not to cancel the driving reservation.

The selection of whether or not to cancel the operation reservation is made by turning the jog dial 58 to alternately select "do not" and "do" like the display screens 60rx and 60ry shown in FIGS. 17(a) and 17(b). , and confirmation of the selection, that is, determination is performed by pressing the jog dial 58 . If the controller determines that "No" has been selected and determined by the user operating the jog dial 58 (S156; YES), the operation reservation will not be canceled, so when the remaining time becomes zero (S157; YES). , the operation end processing (S158) is performed, and the reserved operation processing S150b is finished, and the process returns to the main control processing (FIG. 8). In the operation end process (S158), an operation end input (operation end information) is output to the above-described main control process.

On the other hand, if the controller determines that "Yes" has been selected and determined by the user's operation of the jog dial 58 before the remaining time until the shutdown time becomes zero (S156; NO) (S156; NO), the driving reservation will be canceled, so the display screen 60rz shown in FIG. Then, after finishing the reserved operation process S150b, the process returns to the main control process (FIG. 8). After the operation reservation is canceled, as in the case of normal manual operation (S120, S140 in FIG. 9), the user operates the operation ON/OFF button 55 to input operation OFF information (S152; YES), the manual operation process (S151) is repeatedly performed by the reserved operation process S150a (S152; NO).

In the oven cooking apparatus 10 configured as described above, the user can set the timing to start heating from the operation panel 50 as month/day information (operation start date and time) and time information (operation start time) as shown in FIGS. When the controller of the operation panel 50 determines that the start timing has arrived based on the current month/day information and time information (S15 in FIG. 8; YES), the lower and upper heaters Heating of 41 and 42 is started (S201 in FIG. 10). As a result, the user can directly set the heating start timing based on the month and day information and the time information when using the operation reservation (reservation function), thereby making it difficult for the user to make an erroneous setting in the operation reservation. Therefore, for example, even reservations for the next day or later are less likely to be mistaken.

In addition, in the oven cooking apparatus 10 configured as described above, the user can set the end timing of heating with time information (operation-off time) from the operation panel 50 as shown in FIGS. 14 and 15. If the controller of the operation panel 50 determines that the end timing of the start timing has arrived based on the current month and day information and time information (S157 in FIG. 16(b); YES), the lower and upper Heating of the heaters 41 and 42 is ended (S158 in FIG. 16B, S20 in FIG. 8; YES, S21). As a result, in addition to the start timing of heating, the end timing of heating can also be set in advance. By using the operation reservation (reservation function), the heating of the lower and upper heaters 41 and 42 can be automatically terminated.

Further, in the oven cooking apparatus 10 configured as described above, the operation panel 50 displays (24+X) as the time information of the end timing when the time information indicates the time between midnight and the predetermined time X. It is also possible to accept settings in terms of time information represented by the hour system or the 12-hour system with information for the next day added. For example, in the 24-hour system, the time from midnight to 6:00 or 12:00 after 24:00 is expressed as "24:00 to 30:00" or "24:00 to 36:00". In the 12-hour system, the time from 0:00 to 6:00 or 12:00 after 24:00 can be expressed as "00:00 the next day to 06:00 the next day" or "00:00 the next day to 12:00 the next day." :00". This allows the user to intuitively and easily understand that the time information is the time of the next day.

Further, in the oven cooking apparatus 10 configured as described above, the operation panel 50 displays, as the start timing date information, a predetermined N weeks exceeding one week from the current date (for example, a range of 10 days ahead or 20 days ahead). ) can be accepted. As a result, for example, even when the store is closed continuously for more than one week (seven days) (for example, a long two-week long holiday), the user can set the heating start timing on the month and day. Information and time information can be set directly, and an operation reservation (reservation function) can be used.

The above oven cooking apparatus 10 naturally accepts setting of month and day information within one week (seven days) from the current date as the start timing month and day information. The oven cooking apparatus 10 may be configured to accept only the setting of month and day information and not to accept the setting of month and day information exceeding one week. As a result, since the reservation function can be used only for the most recent one week, it is possible to provide a reservation function that meets the needs of users who cannot set a holiday period exceeding one week due to the business mode of the store.

Further, in the oven cooking apparatus 10 of this embodiment, a case where the controller of the operation panel 50 executes each of the above control processes has been described as an example. ), manual operation processing (FIG. 10), device setting processing (FIG. 12), operation reservation setting processing (FIG. 13), reserved operation processing (FIG. 16), etc. may be executed by the control device 70. Even in such a configuration, it is possible to obtain technical actions and effects by executing each of the above-described control processes and the like in substantially the same manner as the controller of the operation panel 50 described above.

Further, in the oven cooking apparatus 10 of this embodiment, the case in which the two upper and lower heaters 41 and 42 are provided as heaters for heating the inside of the baking furnace has been described as an example. 41 or the upper heater 42) may be configured to heat the inside of the firing furnace 20. FIG. Also, regarding the sensor (temperature detection unit) that detects the temperature in the firing furnace 20, the case where two upper and lower lower temperature sensors 43 and 44 are provided has been described as an example, but only one sensor (lower The temperature sensor 43 or the upper temperature sensor 44 may be configured to detect the temperature inside the firing furnace 20 . Even in such a configuration, substantially the same technical actions and effects as described above can be obtained.
