Abstract

To provide an oven cooking device which reduces unnecessary energy consumption.SOLUTION: In an oven cooking device, when a specified time elapses after last input of an operation input from an operation panel during an operation period (S32; YES), a controller of the operation panel forcibly terminates heating control of lower and upper heaters by power-off processing of step 34. For example, even if a user forgets to turn off the power by operating an operation on / off button of the oven cooking device after business end or the like, when the specified time elapses after last input of the operation input from the operation panel, heating control of the upper and lower heaters is forcibly terminated by the controller. Accordingly, it is possible to prevent power consumption by the upper and lower heaters which are relatively large in power consumption. Therefore, it is possible to reduce unnecessary energy consumption.SELECTED DRAWING: Figure 16

Description

Technical Field

[0001] The present invention relates to an oven cooking apparatus for baking food to be cooked such as bread dough.

Background Art

[0002] Patent Document 1 discloses a deck oven (oven cooking apparatus) for baking bread dough. This type of deck oven is often used for business purposes such as bakeries. Also, before using the deck oven, it is necessary to raise the temperature inside the oven to a set temperature suitable for baking by means of a preheating function, which takes about several tens of minutes. Furthermore, when loading food to be cooked such as bread dough into the oven or unloading the cooked food from the oven, opening and closing the oven door is always accompanied, so a temporary drop in the temperature inside the oven is inevitable. Therefore, after once raising the temperature inside the oven to the set temperature, there are many cases where the oven is continuously heated until near the closing time of the store.

Summary of the Invention

Problems to be Solved by the Invention

[0004] As described above, in the case of a deck oven for business use, once the heating of the oven is started, the product specifications are often set on the premise that the inside of the oven is continuously heated almost during business hours. Therefore, for example, when the user forgets to turn off the power of the deck oven around the closing time of business, there is a possibility that the heating inside the oven will continue until the next business day. In such a case, there is a problem of causing unnecessary energy consumption. An object of the present invention is to provide an oven cooking apparatus that is less likely to cause unnecessary energy consumption.

Means for Solving the Problems

[0005] In order to solve the above problems, the present invention provides a baking oven for baking an object to be cooked, a heater disposed in the baking oven so as to be heatable, an input unit for receiving an operation input from a user, A door that opens and closes the opening of a baking furnace used for loading and unloading the object to be processed, and and a control unit for performing heating control of the heater based on the operation input. During the operation period from when operation start information for instructing the control unit to start the heating control is input from the input unit as an operation input until operation end information for instructing the control unit to end the heating control is input from the input unit as an operation input, the control unit continuously performs the heating control. ri During the operation period, when a predetermined time has elapsed since the last operation input, the control unit forcibly ends the heating control of the heater. An oven cooking device, wherein the operation input to be input during the operation period is, in addition to the information received by the input unit, the opening / closing information of the door indicating the state of being closed after the door is opened, and while the information input by the input unit or the opening / closing information of the door is being input, the control unit continuously performs heating control, and when a predetermined time has elapsed since the information input by the input unit or the opening / closing information of the door was last input, the control unit forcibly terminates the heating control of the heater An oven cooking apparatus is provided, which is characterized by the above.

[0006] In the oven cooking apparatus configured as described above, during the operation period, when a predetermined time has elapsed since the last operation input, the control unit forcibly ends the heating control of the heater. For example, even when a user forgets to turn off the power of the oven cooking apparatus after business hours or the like, when a predetermined time has elapsed since the last operation input, the heating control of the heater is forcibly ended by the control unit. This makes it possible to prevent power consumption by the heater, which consumes relatively large amounts of power. Therefore, unnecessary energy consumption can be made less likely to occur. Also, The operation input to be input during the operation period is, in addition to the information received by the input unit, the opening / closing information of the door indicating the state of being closed after the door is opened, and while the information input by the input unit or the opening / closing information of the door is being input, the control unit continuously performs heating control, and when a predetermined time has elapsed since the information input by the input unit or the opening / closing information of the door was last input, the control unit forcibly terminates the heating control of the heater. For example, during the use of the oven cooking device, the user inputs by operating the input unit, opens and closes the door to load an object to be processed such as bread dough into the baking furnace or unload the object to be processed after baking from the baking furnace, and the information by the input unit or the opening / closing information of the door is input as the operation input. As a result, during the use of the oven cooking device, the time until the heating control of the heater is forcibly terminated is extended each time the input unit is operated or the door is opened and closed. Thereby, it is possible to prevent the occurrence of a situation in which the heating control is interrupted while the user is using the oven cooking device.

[0007] In order to solve the above problems, the present invention provides an oven cooking device comprising a baking furnace for baking an object to be cooked, a heater disposed in the baking furnace so as to be heatable, an input unit for receiving an operation input from a user, and a control unit for performing heating control of the heater based on the operation input. During an operation period from when operation start information for instructing the control unit to start the heating control is input from the input unit as an operation input until operation end information for instructing the control unit to end the heating control is input from the input unit as an operation input, the control unit continuously performs the heating control. During the operation period, when a predetermined time has elapsed since the operation input was last input, the control unit forcibly ends the heating control of the heater. The operation input to be input during the operation period is, in addition to the information received by the input unit, operation start information input from a dough conditioner that is configured to be interlocked with the oven cooking device and performs a pre-stage process of heating the object to be cooked in the baking furnace. While the information input by the input unit or the operation start information input from the dough conditioner is being input, the control unit continuously performs the heating control. When a predetermined time has elapsed since the information input by the input unit or the operation start information input from the dough conditioner was last input, the control unit forcibly ends the heating control of the heater. The present invention provides an oven cooking device characterized by the above.

[0008] In the oven cooking device configured as described above, during the operation period, when a predetermined time has elapsed since the last operation input was made, the control unit forcibly terminates the heating control of the heater. For example, even if the user forgets to turn off the power of the oven cooking device after business hours or the like, when a predetermined time has elapsed since the last operation input was made, the heating control of the heater is forcibly terminated by the control unit. This makes it possible to prevent power consumption by the heater, which has a relatively high power consumption. Therefore, it is possible to make it difficult for unnecessary energy consumption to occur. Also, the operation input to be made during the operation period is, in addition to the information received by the input unit, operation start information input from a dough conditioner that is configured to be interlocked with the oven cooking device and performs a pre-stage process of heating the object to be cooked in the firing furnace. While the information input by the input unit or the operation start information input from the dough conditioner is being input, the control unit continuously performs the heating control. When a predetermined time has elapsed since the information input by the input unit or the operation start information input from the dough conditioner was last input, the control unit forcibly terminates the heating control of the heater. For example, during the use of the oven cooking device, when the user makes an input by operating the input unit or executes a pre-stage process of heating the object to be cooked in the firing path with the dough conditioner, the information by the input unit or the operation start information is input from the dough conditioner. As a result, during the use of the oven cooking device, the time until the heating control of the heater is forcibly terminated is extended each time the input unit is operated or the dough conditioner is used. This can prevent the occurrence of a situation where the heating control is interrupted while the user is using the oven cooking device.

[0015] As shown in FIG. 3, an electric control box 17 for housing electrical components (electronic components constituting a control device 70 and the like described later) that control the lower and upper heaters 41, 42, the water supply valve 48 of the steam generation unit 47, etc., which will be described later, is provided in the machine room 12 in the casing 11. Electrical wiring and the like are provided so that AC power supplied from an external commercial power source can be supplied to the lower and upper heaters 41, 42, and DC power converted from AC can be supplied to the electric control box 17. The electric control box 17 has a substantially rectangular parallelepiped shape with electrical components housed inside, and leg portions 17a are provided at the front and rear of the lower part of the electric control box 17.

[0016] As shown in FIGS. 2 and 5, the baking furnace 20 bakes objects to be cooked such as bread dough and confectionery dough, and has a substantially rectangular parallelepiped shape with a front opening 20a for loading and unloading the objects to be cooked formed on the front surface. A heat insulating material 22 made of glass wool is provided on the outer peripheral surface of the baking furnace 20, and an outer plate 23 made of a stainless steel sheet metal member is further provided on the outer peripheral surface of the heat insulating material 22 (see FIG. 3). The heat inside the baking furnace 20 is less likely to be transmitted to the surroundings including the casing 11 and the machine room 12 by the heat insulating material 22. As shown in FIG. 3, a groove portion 22a extending in the front-rear direction is formed on the left side portion of the upper surface of the heat insulating material 22 covering the upper side of the baking furnace 20, and various components of the exhaust mechanism 30 of the baking furnace 20 described later are disposed in this groove portion 22a.

[0017] An illumination window (not shown) is provided at substantially the center in the vertical and front-rear directions on the right side surface of the baking furnace 20 on the machine room 12 side, and a recess (not shown) is formed in the heat insulating material 22 covering the right outer peripheral surface on the machine room 12 side of the baking furnace 20 at a position facing the illumination window. As shown in FIG. 3, an in-furnace lamp 24 using LED illumination for illuminating the inside of the baking furnace 20 is attached to the outer plate 23 using a bracket 25. The on-off of the in-furnace lamp 24 is controlled by a controller of an operation panel 50 described later. In this embodiment, the in-furnace lamp 24 lights up from after the power of the oven cooking apparatus 10 is turned on until it is turned off.

[0018] As shown in FIGS. 1 and 2, a door 21 is provided on the front side of the baking furnace 20 so as to be openable and closable, and the door 21 is rotatably supported around a horizontal axis by a bracket 16 provided at the lower part of the front panel 15a. As shown in FIGS. 2, 4, and 5, a ceramic furnace floor plate 27 is provided at the lower part of the baking furnace 20, and a tray containing an object to be cooked can be placed above the furnace floor plate 27 inside the baking furnace 20. Left and right guides 28 extending in the front-rear direction are provided at both left and right edge portions of the furnace floor plate 27, and a guide 29 extending in the left-right direction is provided at the rear edge portion of the furnace floor plate 27.

[0019] As shown in FIGS. 3 and 5, an opening / closing mechanism 34 for opening and closing an exhaust passage 31 is provided above the firing furnace 20. The opening / closing mechanism 34 includes a shutter 35 provided so as to be movable back and forth above the upper end opening of the exhaust pipe 32, an operation bar 36 provided in the groove portion 22a of the heat insulating material 22 for moving the shutter 35 back and forth, and an operation knob 37 provided at the front end portion of the operation bar 36 on the front side of the casing 11. The shutter 35 covers the upper end opening of the exhaust pipe 32 in such a manner that the opening degree can be adjusted. At the position of the shutter 35 shown in FIG. 5, the upper end opening of the exhaust pipe 32 is in a completely closed state. When the shutter 35 is moved forward to a position not directly above the upper end opening of the exhaust pipe 32, the upper end opening of the exhaust pipe 32 is completely opened.

[0020] As shown in FIG. 5, a heater 40 is provided in the firing furnace 20. In this embodiment, a lower heater 41 is provided below the furnace floor plate 27 at the lower part of the firing furnace 20, and an upper heater 42 is provided at the upper part of the firing furnace 20. The lower and upper heaters 41 and 42 are formed of heater elements made of substantially U-shaped sheathed heaters with open right sides. The lower heater 41 is arranged by arranging three heater elements side by side in the front-rear direction, and the upper heater 42 is arranged by arranging four heater elements side by side in the front-rear direction. The AC power supplied to the lower and upper heaters 41 and 42 is controlled to be turned on and off by semiconductor switches, and the control is performed by a control device 70 described later.

[0021] A lower temperature sensor 43 is provided at the lower part of the right side surface inside the firing furnace 20, and an upper temperature sensor 44 is provided at the upper part of the right side surface inside the firing furnace 20. The lower temperature sensor 43 is disposed between the foremost heater element and the second heater element from the front of the lower heater 41, and is used to control the lower heater 41. Further, the upper temperature sensor 44 is disposed at a position between the second heater element and the third heater element from the front below the upper heater 42, and is used to control the upper heater 42. A guard member (not shown) is provided in front of the upper temperature sensor 44 on the upper part of the right side surface of the firing furnace 20. In FIG. 5, since the upper heater 42 and the upper temperature sensor 44 appear in front of the A-A cross-section line shown in FIG. 1, they are represented by imaginary lines (two-dot chain lines).

[0022] A steam generation part 47 is provided at the upper part inside the firing furnace 20, and the steam generation part 47 is disposed above the upper heater 42 inside the firing furnace 20. The steam generation part 47 heats the water supplied from a water supply source through a water supply pipe 49 by the upper heater 42 to vaporize it and generate steam inside the firing furnace 20. The steam generation part 47 is mainly composed of a steam generation dish, a heat storage plate, a water supply part (all not shown), etc. The water from the water supply source is sent to the upper side of the heat storage plate and vaporizes by contacting the heat storage plate and the steam generation dish to become steam. The vaporized steam rises upward, hits the ceiling surface of the firing furnace 20, and then flows into the lower part of the firing furnace 20 or the front part of the firing furnace 20 through the passage between the steam generation dish and the inner side surface of the firing furnace 20. A water supply valve 48 is installed in the machine room 12 in the water supply pipe 49, and the water from the water supply source is sent to the upper side of the heat storage plate through the water supply pipe 49 when the water supply valve 48 is opened.

[0023] As shown in FIGS. 1 to 4, a machine room panel 18 is provided on the right side of the front surface of the casing 11. The machine room panel 18 includes an operation panel 50 and a buzzer unit 19. As shown in FIG. 6, the operation panel 50 includes a display unit 51, six operation buttons (steam button 52, home button 53, return button 54, operation on / off button 55, start / stop button 56, timer extension button 57, jog dial 58), and a controller (not shown). The controller is a microcomputer having a CPU, a RAM, a ROM (including an EEPROM), a clock function (timing unit), etc., similar to the microcomputer of the control device 70, for example, and functions as a control unit in this embodiment.

[0024] In this embodiment, the display unit 51 uses a liquid crystal panel (LCD panel) and is controlled by the controller to appropriately display the operating state of the oven cooking device 10, various setting states, the detected temperature in the baking furnace 20, etc. The six operation buttons 52 to 57 and the jog dial 58 are also connected to this controller, and based on their inputs, the controller is configured to control normal operations (manual operation and program operation), reservation operation, and various settings related thereto, which will be described later. In this embodiment, the input information of these operation buttons 52 to 57 and the jog dial 58 is input to the controller by hardware interruption. The buzzer unit 19 is also connected to the controller of the operation panel 50 and is controlled to output a predetermined buzzer sound in association with operation control, etc. Further, an external device such as a doucon 90 is connected to the controller of the operation panel 50 via an external input terminal 59.

[0025] As shown in FIG. 7, the oven cooking apparatus 10 includes a control device 70, and the control device 70 is connected to a lower heater 41, an upper heater 42, a lower temperature sensor 43, an upper temperature sensor 44, a water supply valve 48, and an operation panel 50. The control device 70 has a microcomputer (not shown), and the microcomputer includes a CPU, a RAM, a ROM (including an EEPROM), a timer, and a clock function (timekeeping unit) (all not shown) that are respectively connected via a bus. In this embodiment, the control device 70 mainly controls the power supply to the lower and upper heaters 41 and 42.

[0026] 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 according to the main program shown in FIG. 8. In this embodiment, the case where the controller of the operation panel 50 executes the main program will be exemplified and described. Note that this main program is stored in the ROM of the controller. Also, the commercial power supplied to the oven cooking apparatus 10 is converted into DC power and supplied to the operation panel 50 and the control device 70 even in the power-off state by operating the operation panel 50 (standby state). Therefore, it should be noted that in this specification, turning on or off the power of the oven cooking apparatus 10 means turning on or off the AC power supplied to the lower and upper heaters 41 and 42.

[0027] [Main Control Process] As shown in FIG. 8, when the controller of the operation panel 50 is activated in the standby state, first, by the initialization process in step 10, the work area, flags, etc. secured in the RAM are set to the initial values, or each setting information regarding the manual operation stored in the previous power-off process (S24) is read from a non-volatile memory such as an EEPROM. After that, in step 11, the controller determines whether there is an operation start input (operation start information). The operation start input is information input, for example, when the user continuously presses the operation on / off button 55 of the operation panel 50 for 1 second or more. If there is an operation start input, after determining "YES", the power switch that supplies power to the lower heater 41 and the upper heater 42 is turned on by the power-on process in step 12. That is, the oven cooking device 10 is powered on. After that, after starting the monitoring timer process in step 13, the process proceeds to the normal operation process in step 14. The monitoring timer process is a process for monitoring the non-operation time in the normal operation process after power-on, and will be described later with reference to FIGS. 16 and 17. Also, the normal operation process (S100) will be described later with reference to FIGS. 9 to 14.

[0028] On the one hand, if there is no operation start input in step 11, since the user has not yet operated the operation input / switch button 55 of the operation panel 50 (because the oven cooking device 10 is powered off), the controller of the operation panel 50 determines "NO" and in step 15, it determines whether there is a reserved operation, that is, whether the setting of "performing" the operation reservation is made. The reserved operation is an operation mode in which the oven cooking device 10 performs the following manual operation process (S200) at the preset start date and time and end time of the operation, and is performed when the operation reservation "is performed" is set in the operation reservation setting process (S430) of the device setting process (S400) described later. If there is a reserved operation, after determining "YES" in step 15, it further determines in step 16 whether the set reserved date and time has arrived. In this determination process of step 16, the current date and time information output from the clock function of the controller of the operation panel 50 is compared with the reserved date and time information. When the current date and time matches the reserved date and time or has passed the reserved date and time, it determines "YES", performs the power-on process in step 17, and then starts the monitoring timer process in step 18 and transfers to the reserved operation process in step 19. The power-on process in step 17 is the same as the aforementioned power-on process (S12). The monitoring timer process in step 18 is a process for monitoring the non-operation time in the reserved operation process, and the algorithm is the same as the monitoring timer process in step 13.

[0029] If there is no reserved operation in step 15 or the current date and time has not reached the reserved date and time in step 16, it determines "NO" in those steps and transfers the process to step 20. In step 20, it determines whether there is a tofu maker interlock. The tofu maker interlock is an operation mode in which operation information is directly input (hardware interruption) from the tofu maker 90 to the controller of the operation panel 50 via the external input terminal 59, so that the tofu maker 90 can operate the oven cooking device 10 in the same way as the user operates the operation panel 50. The presence or absence of the tofu maker interlock can be set in the tofu maker interlock setting process (S410) of the device setting process (S400) described later. Note that the tofu maker 90 is an example of an external device, and a device that can interlock the oven cooking device 10 like this may be other kitchen appliances other than the tofu maker.

[0030] If there is a rice cooker interlock, after determining "YES" in step 20, it is further determined in step 21 whether there is an input of operation information (rice cooker input) from the rice cooker 90. If there is a rice cooker input, it is determined "YES", and after performing the power-on process in step 22, the monitoring timer process is started in step 23 and the process proceeds to the rice cooker interlock process in step 24. The power-on process in step 22 is the same as the above-described power-on process (S12), and the monitoring timer process in step 23 (monitoring the non-operation time in the rice cooker interlock process) is the same as the monitoring timer process in step 13.

[0031] On the other hand, if there is no rice cooker interlock in step 20 or there is no rice cooker input in step 21, it is determined "NO" in those steps and it is determined in step 25 whether there is an operation end input. The operation end input is operation end information input when operation end processing (S140, S173, S177) is performed in the normal operation process (S100) or the rice cooker interlock process (S170) described later. If there is an operation end input (operation end information), it is determined "YES", and then the power switch or the like that supplies power to the lower heater 41 and the upper heater 42 is turned off by the power-off process in step 26. That is, the oven cooking device 10 is turned off. Then, after storing (storing) each setting information (set temperature, timer time, etc.) regarding the currently set manual operation in a non-volatile memory such as an EEPROM, the process returns to step 11.

[0032] On the contrary, if there is no operation end input in step 25, since the oven cooking device 10 is not operating (before the start of operation), it is determined "NO" and the process returns to step 11 to determine whether there is an operation start input. That is, the controller of the operation panel 50 repeatedly performs the determination processes in steps 11, 15, and 20 described above until it proceeds to any one of the normal operation process in step 14, the reservation operation process in step 19, and the rice cooker interlock process in step 24.

[0033] [Normal operation process] Next, while referring to FIG. 9, the normal operation process by the normal operation program will be described. In this embodiment, the normal operation program is stored in the ROM of the controller of the operation panel 50. As shown in FIG. 9, first, in step 110, the controller displays a home menu on the display unit 51 of the operation panel 50. As shown in FIG. 6, the display screen 60aa of the home menu is composed of, for example, a home icon 61, a manual operation bar 62, a program operation bar 63, a device setting bar 64, and an inspection bar 65. Note that 12:34 shown at the upper left of the display screen 60aa is a 24-hour format display of the current time (12:34) by the clock function of the controller. Although not shown, in the state where the home menu is displayed on the display unit 51, similar to step 20 of the main control process, it is determined whether there is an input of operation information (dokon input) from the dokon 90. Therefore, when it is determined that there is a dokon input, the process shifts from the state where the home menu is displayed to the dokon interlock process (S170) described later.

[0034] 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 turning the jog dial 58 of the operation panel 50 in the circumferential direction. A white frame is displayed around the item bar in the selected state (in FIG. 6, the manual operation bar 62 is in the selected state). For the item bar in the selected state, the selection of the item bar is determined when the user presses the jog dial 58 in the axial direction.

[0035] When the controller of the operation panel 50 determines that the manual operation bar 62 has been selected and determined by the operation of the jog dial 58 by the user (S110; "manual operation"), the process proceeds to the manual operation process in step 200. The manual operation process (S200) will be described later with reference to FIGS. 10 and 11. Then, when the manual operation process in step 200 ends, it is determined in the next step 120 whether the operation is turned off. If it is determined that the operation is not turned off, it is determined as "NO", and the process returns to the manual operation process (S200) again. If the operation is turned off, it is determined as "YES" and the process proceeds to the operation end process in step 140. The operation being turned off, that is, the operation end input (operation end information), is input when the user continuously presses the operation on / off button 55 for 1 second or more. That is, it is input when the user operates to turn off the power of the oven cooking device 10. Although not shown, when it is determined in step 120 that the user has pressed the home button 53 or the return button 54, the process returns to step 110 and the home menu is displayed on the display unit 51.

[0036] When the controller of the operation panel 50 determines that the program operation bar 63 has been selected and determined by the operation of the jog dial 58 by the user (S110; "Program operation"), the process proceeds to the program operation process in step 300. While the manual operation process is carried out while inheriting the operation conditions such as the set temperature and timer time at the previous manual operation, in this program operation process (S300), an arbitrary operation condition (cooking setting program) is selected from a plurality of set temperatures and timer times set in advance by the user, and the process is carried out based on it. That is, except that the user can select a cooking setting program in advance, in the program operation process (S300), the same process as the manual operation process (S200) described later is carried out. When the program operation process ends, it is determined in the next step 130 whether the operation is turned off. If it is not determined that the operation is turned off, it is determined as "NO", and the process returns to the program operation process (S300) again. If the operation is turned off, it is determined as "YES", and the process proceeds to the operation end process in step 140. Although not shown, when it is determined in step 130 that the home button 53 or the return button 54 has been pressed by the user, the process returns to step 110 and the home menu is displayed on the display unit 51.

[0037] In the operation end process (S140), an operation end input (operation end information) is output to the main control process by the main program described above. When the operation end process (S140) ends, this normal operation process ends and the process returns to the main control process (FIG. 8) by the main program.

[0038] When the controller of the operation panel 50 determines that the device setting bar 64 has been selected and determined by the operation of the jog dial 58 by the user (S110; "Device setting"), the process proceeds to the device setting process in step 400. This device setting process (S400) will be described later with reference to FIG. 12. In step 400, as will be described later, the device setting process is repeatedly executed until the home button 53 of the operation panel 50 is pressed.

[0039] 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 process proceeds to the inspection process in step 500. In this inspection process (S500), for example, error information and notification information currently occurring in the oven cooking device 10 are listed and displayed on the display unit 51 as inspection items. The error information is, for example, abnormal information of the lower temperature sensor 43, the upper temperature sensor 44, the controller board, etc. The notification information is, for example, detailed contents of the error information, a message prompting the user to contact a service company, etc. In step 500, the display screen by the inspection process is repeatedly executed until the home button 53 of the operation panel 50 is pressed.

[0040] [Manual operation process] Next, referring to FIGS. 10 and 11, the manual operation process by the manual operation program will be described. In this embodiment, the manual operation program is stored in the ROM of the controller of the operation panel 50.

[0041] As shown in FIG. 10, the controller of the operation panel 50 first sends instruction information (heating start information) to start heating by the lower and upper heaters 41 and 42 to the control device 70 by starting the preheating in step 201. This heating start information includes each setting information (set temperature, timer time, etc.) regarding the previous manual operation stored in the non-volatile memory by the controller in the power-off process (S26 in FIG. 8), and the controller reads out these each setting information from the non-volatile memory. The heating start information is the heating level of the lower and upper heaters 41 and 42, the set temperature, the set time of the timer, etc. The heating level is a step display in which the output can be set discontinuously for each of the lower and upper heaters 41 and 42, and in this embodiment, the ratio (0%, 20%, 40%, 60%, 80%, 100%) to the maximum output of the heater can be set in 6 steps from level 0 (0%) to level 5 (100%).

[0042] When the control device 70 receives such heating start information, it turns on the power switch that controls the power supply to the lower and upper heaters 41 and 42, supplies power equivalent to a preset heating level to these heaters 41 and 42, and starts temperature control for the lower and upper heaters 41 and 42. As a result, since the temperature in the firing furnace 20 begins to rise, the lower temperature information and the upper temperature information output from the lower temperature sensor 43 and the upper temperature sensor 44 are obtained via the control device 70 by detecting the upper and lower temperatures in step 202. Then, the lower and upper temperature information and the like obtained in step 202 are output to and displayed on the display unit 51 of the operation panel 50 in step 203.

[0043] In step 203, the controller of the operation panel 50 displays, for example, the display screen 60ma shown in FIG. 11(a) on the display unit 51. On this display screen 60ma, as information immediately after the start of preheating, "Preheating", "M Manual Operation", the current temperature of 30°C and the set temperature of 200°C and the heating level of 5 for the upper fire (the upper part inside the furnace), the current temperature of 30°C and the set temperature of 200°C and the heating level of 3 for the lower fire (the lower part inside the furnace), the timer time of 10 minutes 00 seconds, etc. are displayed.

[0044] Then, the controller of the operation panel 50 determines in step 204 whether the temperature in the firing furnace 20 has reached the set temperature. In the firing furnace 20 of this embodiment, since the lower and upper heaters 41 and 42 are provided in the furnace, when the temperatures detected by the corresponding lower and upper temperature sensors 43 and 44, that is, both the lower temperature and the upper temperature are equal to or higher than the set temperature, the controller determines that the temperature in the firing furnace 20 has reached the set temperature.

[0045] 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 their respective set temperatures and the controller determines "YES", the preheating ends. Therefore, in step 205, for example, the display screen 60mb of "Standby" shown in FIG. 11(b) is displayed on the display unit 51, or the buzzer unit 19 is sounded with a predetermined beep sound to inform the user that the preheating has ended. On the other hand, when either the lower temperature information or the upper temperature information has not reached the set temperature and the controller determines "NO", the process returns to step 202 again.

[0046] When the preheating ends and the main heating starts, step 206 determines whether there is an input to the start / stop button 56. That is, since the temperature in the firing furnace 20 has reached the set temperature, the user opens the door 21 of the oven cooking apparatus 10 and carries a tray containing an object to be cooked such as bread dough into the firing furnace 20. Then, when the door 21 is closed, a timer that measures the preset firing time (10 minutes and 00 seconds in the example of FIG. 11(c)) is started, so the user presses the start / stop button 56 on the operation panel 50.

[0047] When there is an input to the start / stop button 56 in step 206 and it is determined "YES", the countdown of the timer is started, and in the next step 207, for example, the display screen 60mc of "Cooking" shown in FIG. 11(c) is displayed on the display unit 51. In this example of the display screen 60mc, until the remaining time of the timer, 9 minutes and 59 seconds, reaches zero, that is, until the time runs out, the lower temperature information, the upper temperature information, and the remaining time information are sequentially updated and the display continues (when "NO" in S209).

[0048] Although not shown in FIG. 10, the algorithm may be configured so that the input determination of the start / stop button 56 can be performed even during the period from the start of preheating to the end of preheating described above. In this case, even before the temperature in the firing furnace 20 reaches the set temperature, when it is determined that the start / stop button 56 has been input, the countdown of the timer is started and, by step 207, for example, the algorithm is configured so that the display screen 60mc of "Cooking" shown in FIG. 11(c) is displayed on the display unit 51.

[0049] When the controller of the operation panel 50 determines "YES" in step 208 that the remaining time of the timer has become zero, in step 209, for example, the display screen 60md of "Cooking Completed" shown in FIG. 11(d) is displayed on the display unit 51 or the buzzer unit 19 is sounded with a predetermined beep sound to notify the user that the cooking has been completed. As a result, since it is highly probable that the object to be cooked in the firing furnace 20 has been fired, the user opens the door 21 of the oven cooking apparatus 10 and takes out the tray containing the cooked object such as the baked bread from the firing furnace 20.

[0050] Thereafter, the controller returns to the normal operation process (FIG. 9) after finishing this manual operation process, and if it is determined "NO" in step 120 that the operation is not turned off, it shifts to the manual operation process (S200) again. That is, when the user does not press the operation on / off button 55 on the display screen 60md of "Cooking Completed" (when the user does not perform an operation to turn off the power of the oven cooking apparatus 10), the manual operation process (S200) is executed again. As a result, when the temperature in the firing furnace 20 drops below the set temperature due to the opening and closing of the door 21 by carrying out the object to be cooked, etc., after the start of preheating in step 201, it is preheated until it reaches the set temperature (S202 to S204), and the display screen 60ma is displayed on the display unit 51 (FIG. 11(a)), and when it reaches the set temperature, the display screen 60mb is displayed (FIG. 11(b)).

[0051] [Equipment Setting Process] Next, with reference to FIGS. 12 and 14, the device setting process by the device setting program will be described. In this embodiment, the device setting program is stored in the ROM of the controller of the operation panel 50. As shown in FIG. 14(a), when the device setting bar 64 is selected and determined by operating the jog dial 58 on the display screen 60ab of the home menu, as shown in FIG. 12, the controller first displays a device setting menu on the display unit 51 of the operation panel 50 in step 401.

[0052] As shown in FIG. 14(b), on the display screen 60sa of the device setting menu, for example, setting items such as "Doucon linkage", "Operation reservation", "Steam time", "Rapid preheating mode", and "Timer extension time" are displayed on the first page. Although the pages after the second page are hidden below the screen and not shown, items such as "Screen brightness", "Buzzer volume", "Buzzer type at end", "Buzzer interval at end", and "Buzzer length at end" are also displayed by page switching.

[0053] When the controller of the operation panel 50 determines that the item "Doucon linkage" has been selected and determined by the user's operation of the jog dial 58 (S401; "Doucon linkage"), the process proceeds to the Doucon linkage setting process in step 410. This Doucon linkage setting process (S410) will be described later with reference to FIGS. 13 and 14.

[0054] When the controller of the operation panel 50 determines that the item "Operation reservation" has been selected and determined by the user's operation of the jog dial 58 (S401; "Operation reservation"), the process proceeds to the operation reservation setting process in step 430. In this operation reservation setting process (S430), the date information (operation start date and time), time information (operation start time), and time information (operation end time) of the start timing of heating are set.

[0055] When the controller of the operation panel 50 determines that the item of "steam time" has been selected and determined by the user's operation of the jog dial 58 (S401; "steam time"), the process proceeds to the steam time setting process in step 450. In this steam time setting process (S450), when the user presses the steam button 52 of the operation panel 50, the time (steam time) for generating steam from the steam generation unit 47 is set within the range of 1 second to 5 seconds.

[0056] When the controller of the operation panel 50 determines that the item of "rapid preheating mode" has been selected and determined by the user's operation of the jog dial 58 (S401; "rapid preheating mode"), the process proceeds to the rapid preheating mode setting process in step 470. In this rapid preheating mode setting process (S470), after the power of the oven cooking device 10 is turned on, it is set whether to perform preliminary heating (in the rapid preheating mode) by setting the outputs of the lower and upper heaters 41 and 42 to the maximum during the first (initial) preheating (whether to perform the rapid preheating mode or not).

[0057] When the controller of the operation panel 50 determines that the item of "timer extension time" has been selected and determined by the user's operation of the jog dial 58 (S401; "timer extension time"), the process proceeds to the timer extension time setting process in step 490. In this timer extension time setting process (S490), when the user presses the timer extension button 57 of the operation panel 50, the time (timer extension time) for extending the timer time is set within the range of 10 seconds to 60 seconds.

[0058] Note that the description is omitted for the cases where items such as "screen brightness", "buzzer volume", "end buzzer type", "end buzzer interval", and "end buzzer length" are selected. When each of these setting processes (S410, S430, S450, S470, S490, etc.) is completed, the process returns to step 401, and the display screen 60sa of the device setting menu is displayed again. When the home button 53 is pressed, the display screen 60ab of the home menu is displayed.

[0059] [Doukong Interlock Setting Process] Next, with reference to FIGS. 13 and 14, the doikon interlock setting process by the doikon interlock setting program will be described. In this embodiment, the doikon interlock setting program is stored in the ROM of the controller of the operation panel 50.

[0060] As shown in FIGS. 14(b) and 14(c), when the item of "doikon interlock" is selected and determined by operating the jog dial 58 in the device setting menu, the display on the display unit 51 transitions from the display screen sa to the display screen sb. As shown in FIG. 13, after the controller of the operation panel 50 displays the doikon interlock setting on the display unit 51 of the operation panel 50 in step 411, if it is determined in step 412 that doikon interlock is to be performed (S412; YES), after selecting "do" for interlock in step 413, the operation menu is displayed in step 415. On the other hand, if it is determined in step 412 that doikon interlock is not to be performed (S412; NO), after selecting "do not" for interlock in step 414, it is determined in step 419 whether to determine the setting content.

[0061] As shown in FIG. 14(d), on the display screen 60da of the operation menu, "M manual operation" and "P program operation" are displayed. When the controller of the operation panel 50 determines that the item of "M manual operation" has been selected and determined by the user's operation of the jog dial 58 (S416; YES), manual operation is selected in step 417, and when the controller of the operation panel 50 determines that the item of "P program operation" has been selected and determined (S415; NO), program operation is selected in step 418. When "P program operation" is selected, the user selects an arbitrary one from up to nine pre-registered cooking setting programs by operating the jog dial 58.

[0062] After the selection of whether to link with the doorknob and the selection of the operation items are completed, the user selects whether to determine the set content (selected content) by pressing the jog dial 58. When the controller of the operation panel 50 determines in step 419 that the set content has been determined (S419; YES), in step 420, the information (set information) of the set content is stored (memorized) in a non-volatile memory such as the EEPROM of the controller. Also, when it is determined that the set content has not been determined even after a predetermined time has elapsed (S419; NO), the process returns to step 411 and the display screen 60sb shown in FIG. 14(c) is displayed again.

[0063] When it is determined in step 419 that the set content has been determined (S419; YES), the display screen 60db shown in FIG. 14(e) is displayed on the display unit 51 in step 421. An example of the display when the set content is "linked with the doorknob" is shown on the display screen 60da. Then, the process returns to the device setting process (S401 in FIG. 12), and the display screen 60sc of the device setting menu as shown in FIG. 14(f) is displayed. Thereby, it can be confirmed that the setting to link with the doorknob is "enabled".

[0064] [Door Knob Linkage Process] Next, referring to FIG. 15, the door knob linkage process by the door knob linkage program will be described. In this embodiment, the door knob linkage program is stored in the ROM of the controller of the operation panel 50. The door knob linkage process is activated when the normal operation process is not performed (S11 in FIG. 8; NO), the operation reservation is set to "not" (S15 in FIG. 8; NO), and the door knob linkage is set to "enabled" (S20 in FIG. 8; YES) and there is a door knob input (S21 in FIG. 8; YES) by the main control process (FIG. 8) by the main program described above.

[0065] In this embodiment, one of the two Doukong interlocking processes S170a and S170b shown in FIGS. 15(a) and 15(b) is executed. That is, on the display screen 60da of the operation menu displayed on the display unit 51 by the Doukong interlocking setting process (S410 in FIG. 13), when the item selected and determined by the user's operation of the jog dial 58 is "M manual operation", the Doukong interlocking process S170a in FIG. 15(a) is executed, and when it is "P program operation", the Doukong interlocking process S170b in FIG. 15(b) is executed.

[0066] First, the Doukong interlocking process S170a in the case of manual operation shown in FIG. 15(a) will be described. The controller of the operation panel 50 first performs a process of starting the manual operation in step 171. Thereby, the manual operation is started. The details of the manual operation have already been described with reference to FIGS. 10 and 11, so they will be omitted here. Then, the manual operation process in this step 171 is repeatedly performed until the user continuously presses the operation on / off button 55 for 1 second or more and the operation-off information is input (S172; NO). When the operation-off information is input (S172; YES), after performing the operation end process (S173), this Doukong interlocking S170a is terminated and the main control process (FIG. 8) is returned to. In the operation end process (S173), an operation end input (operation end information) is output to the aforementioned main control process.

[0067] The Doukong interlocking process S170b in the case of program operation shown in FIG. 15(b) also performs substantially the same process as the Doukong interlocking process S170a in the case of manual operation, but the only difference is that the program operation process is started in the first step 175. Therefore, the program operation process (S175) is repeatedly performed until the operation-off information is input in step 176 (S176; NO), and when the operation-off information is input (S176; YES), after performing the operation end process (S177), this Doukong interlocking S170b is terminated and the main control process (FIG. 8) is returned to, which is the same as in the case of manual operation.

[0068] Incidentally, the program operation process in step 175 is slightly different from the program operation process in step 300 described with reference to FIG. 9 in the normal operation process (S100). In the program operation process in step 300, the process is performed based on any one selected by the user from the pre-registered maximum of nine cooking setting programs, whereas the program operation process executed in step 175 is performed based on the cooking setting program selected in the above-described doukon interlock setting process. To clarify such a difference, in FIG. 15(b), the program operation process in step 175 is given the symbol S300' in parentheses.

[0069] As described above, in the oven cooking apparatus 10 of this embodiment, when the user operates the operation on / off button 55 to turn on the power (S11; YES → S12), the normal operation process (S14) is performed. Even when the user does not operate the operation on / off button 55 (S11; NO), the power may be automatically turned on (S17, S22), and the reservation operation process (S19) or the doukon interlock process (S24) may be performed (see FIG. 8).

[0070] The functions of reservation operation and doukon interlock are assumed for the oven cooking apparatus 10 to be used for business purposes in a store, a workshop, or the like. While the oven cooking apparatus 10 has such a convenient function that the power is automatically turned on, since it is necessary to maintain the temperature in the baking furnace 20 at a set temperature suitable for baking during business hours, there are not a few cases where the power is not turned off until around the business closing time once the power is turned on. Therefore, if the user forgets to turn off the power, the power may remain on until the next business day.

[0071] Therefore, in the oven cooking apparatus 10 of this embodiment, even when a situation occurs where the user forgets to turn off the power of the oven cooking apparatus 10 after business hours or the like, it is provided with a safety control timer function that can automatically turn off the power of the oven cooking apparatus 10 when a predetermined time has elapsed. The monitoring timer process for realizing this function will be described with reference to FIGS. 16 and 17.

[0072] [Monitoring Timer Process] As described above, the monitoring timer process is appropriately activated in the main control process in the controller of the operation panel 50 and executed in parallel with the main control process. In this embodiment, the monitoring timer process is activated (S13, S18, S23) before the normal operation process (S14), the reservation operation process (S19), and the Doucon interlock process (S24) are executed respectively. The monitoring timer program that enables the execution of the monitoring timer process is stored in the ROM of the controller of the operation panel 50.

[0073] As shown in FIG. 16, when the controller of the operation panel 50 activates the monitoring timer process, first, by the initialization process in step 30, the counter value of the timer for timing is set to a predetermined value (for example, a value capable of timing for 3 hours), or the work area, flag, etc. secured in the RAM are set to the initial values. Then, in step 31, the timing starts, that is, the countdown of the timer for timing begins.

[0074] Then, in step 32, it is determined whether a predetermined time has elapsed. If the counter value has not become zero, it is determined as "NO", and then in step 33, it is determined whether there is an operation input to the operation panel 50. The operation input is the input information input from the six operation buttons 52 to 57 and the jog dial 58 provided on the operation panel 50, and the operation information input (Doucon input) from the Doucon 90 connected to the external input terminal 59.

[0075] In this embodiment, since all of these input information and operation information are input to the controller by hardware interrupts, in the determination process of step 33, it is determined whether there is a hardware interrupt due to the input information and operation information during the predetermined period. If there is a hardware interrupt from now on, it is determined as "YES", and if there is no hardware interrupt, it is determined as "NO". For example, when the user presses the steam button 52 or the home button 53 or turns the jog dial 58, it is determined as "YES".

[0076] When there is an operation input and it is determined as "YES", return to step 30, and again set (reset) the counter value to a predetermined value (S30) and restart the countdown (S31). On the contrary, when there is no operation input and it is determined as "NO", return to step 32 to determine whether a predetermined time has elapsed. The predetermined time is set to, for example, 3 hours. Therefore, when 3 hours have elapsed since the user last operated the home button 53, jog dial 58, etc. of the oven cooking apparatus 10 or an operation input was received from the doucon 90, the process proceeds to step 34.

[0077] The power-off process in step 34, similar to the power-off process of the main control process (S26), turns off the power switch etc. that supplies power to the lower heater 41 and the upper heater 42, and stores (stores) each setting information (set temperature, timer time, etc.) regarding the currently set manual operation in a non-volatile memory such as an EEPROM. When the process of step 34 is completed, this monitoring timer process ends. As a result, in the normal operation process (S14), reservation operation process (S19), or doucon interlock process (S24), when the no-operation time without an operation such as the operation of the home button 53 etc. or doucon input continues for a predetermined period or more, the power supply to the lower heater 41 and the upper heater 42 is automatically stopped, so that it becomes possible to prevent wasteful power consumption by the lower and upper heaters 41, 42.

[0078] Note that as described above, when the temperature in the firing furnace 20 is maintained at a predetermined set temperature, the opening / closing information of the door 21 provided so as to be able to open and close the front opening 20a of the firing furnace 20 may be added as an operation input. In this case, for example, a new processing step is added before or after step 33, and in that step, the opening / closing information is acquired to determine whether the door 21 is opened or closed. As a result, during the use of the oven cooking apparatus 10, the time until the heating control of the lower and upper heaters 41, 42 is forcibly terminated is extended each time the door is opened and closed.

[0079] That is, as shown in FIG. 17, the inventors of the present application have confirmed that the temperature inside the baking furnace 20 temporarily decreases when the door 21 is opened and closed. In this example, inside the baking furnace 20, the heating by the lower and upper heaters 41 and 42 is controlled by the control device 70 so that the upper fire (the upper side inside the furnace) is 220° C. and the lower fire (the lower side inside the furnace) is 190° C. as the set temperatures, respectively.

[0080] In FIG. 17, the solid curve indicates the characteristics of the upper fire temperature inside the baking furnace 20 detected by the upper temperature sensor 44, and the dashed curve indicates the characteristics of the lower fire temperature inside the baking furnace 20 detected by the lower temperature sensor 43. The door 21 is opened and closed twice at the timings of time ta and time tc. From the characteristics of the upper fire temperature, it can be confirmed that the temperature decreases by about 7° C. to 10° C. during the period from ta to tb (about 7 minutes) due to the first opening and closing, and during the period from tc to td (about 5 minutes) due to the second opening and closing.

[0081] Therefore, for example, at a predetermined timing, when the upper fire temperature Tu detected by the upper temperature sensor 44 drops to (the set temperature Su of the upper fire - a predetermined threshold temperature Th) or lower (Tu ≦ (Su - Th)), it becomes possible to estimate that the door 21 of the baking furnace 20 has been opened and closed. For example, the predetermined threshold temperature Th is set to 5° C. (4 to 6° C.).

[0082] When the temperature of the baking furnace 20 drops by a predetermined threshold temperature (for example, 10° C.) or more from the set temperature, the heating by the upper heater 42 starts and the temperature rises in a short period. Therefore, although there is a possibility that it may be detected and estimated that the door 21 has been opened and closed even though the door 21 has not been opened and closed, the opening and closing information of the door 21 by such detection is only used as an operation input for resetting the counter value of the timer in the above-described monitoring timer process. Further, when the temperature inside the baking furnace 20 rises, it is highly probable that the user is using the oven cooking apparatus 10 for cooking or the like. Therefore, even if such false detection occurs, it does not affect the operation of the oven cooking apparatus 10.

[0083] Also, as described above, instead of the algorithm that detects the opening and closing of the door 21 based on whether the temperature drop within a predetermined period is equal to or higher than a predetermined threshold temperature (equal to or higher than the predetermined threshold temperature → there is opening and closing, lower than the predetermined threshold temperature → there is no opening and closing) and outputs the opening and closing information, the algorithm may be configured to detect the opening and closing of the door 21 based on whether the temperature gradient per unit time is equal to or higher than a predetermined threshold (equal to or higher than the predetermined threshold temperature → there is opening and closing, lower than the predetermined threshold temperature → there is no opening and closing) and output the opening and closing information.

[0084] Furthermore, a sensor capable of detecting the opening and closing of the door 21 (for example, a micro switch, a reed switch, etc.) may be used for detection, and the output of the sensor may be used as the opening and closing information and as an operation input in the above-described monitoring timer process. As a result, it becomes possible to detect the opening and closing of the door 21 with high precision in terms of hardware, so that the reset of the timer in the monitoring timer process can be performed more reliably.

[0085] In the oven cooking apparatus 10 configured as described above, during the operation period, when a predetermined time has elapsed since the last operation input was made from the operation panel 50 (S32; YES), the controller of the operation panel 50 forcibly terminates the heating control of the lower and upper heaters 41 and 42 by the control device 70 through the power-off process in step 34. The operation period is the period during which power is supplied to the lower and upper heaters 41 and 42. For example, even if a situation occurs where the user forgets to turn off the power by operating the operation on / off button 55 of the oven cooking apparatus 10 after business hours or the like, when a predetermined time has elapsed since the last operation input was made from the operation panel 50, the heating control of the lower and upper heaters 41 and 42 is forcibly terminated by the controller. As a result, it becomes possible to prevent power consumption by the lower and upper heaters 41 and 42, which consume relatively large amounts of power. Therefore, it is possible to reduce the occurrence of unnecessary energy consumption.

[0086] In addition, in the oven cooking device 10 configured as described above, since the operation start information as the operation input is also input from the yeast 90, the starting point of the elapse of the predetermined time is when the input is received from the yeast 90. As a result, the time until the heating control of the lower and upper heaters 41 and 42 is forcibly terminated is extended. Therefore, it is possible to prevent the occurrence of a situation in which the heating control in conjunction with the yeast 90 is interrupted.

[0087] In addition, in the oven cooking device 10 configured as described above, the opening / closing information indicating that the door 21 of the baking furnace 20 is opened / closed is also received by the operation panel 50. Thereby, for example, during the use of the oven cooking device 10, the user loads an object to be cooked such as bread dough into the baking furnace 20 or unloads the cooked object from the baking furnace 20. Along with this, the opening / closing information of the door 21 is input to the input unit as an operation input due to the opening and closing of the door 21. Therefore, during the use of the oven cooking device 10, the time until the heating control of the lower and upper heaters 41 and 42 is forcibly terminated is extended each time the door 21 is opened and closed. Therefore, it is possible to prevent the occurrence of a situation in which the heating control is interrupted while the user is using the oven cooking device 10.

[0088] Note that, in the above oven cooking device 10, the case where the controller of the operation panel 50 executes each of the above control processes and the like has been described as an example. However, the main control process (FIG. 8), the normal operation process (FIG. 9), the manual operation process (FIG. 10), the device setting process (FIG. 12), the yeast interlock setting process (FIG. 13), the yeast interlock process (FIG. 15), the monitoring timer process (FIG. 16), etc. may be configured to be executed by the control device 70. Even in such a configuration, similar to the controller of the operation panel 50 described above, the technical actions and effects obtained by executing each of the above control processes and the like can be obtained.

[0089] In addition, in the oven cooking apparatus 10 of this embodiment, although the case where two upper and lower lower and upper heaters 41 and 42 are provided as heaters for heating the inside of the baking furnace has been described as an example, it may be configured to heat the inside of the baking furnace 20 with one heater (lower heater 41 or upper heater 42). Also, regarding the sensor (temperature detection unit) for detecting the temperature inside the baking furnace 20, although the case where two upper and lower lower temperature sensors 43 and upper temperature sensors 44 are provided has been described as an example, it may be configured to detect the temperature inside the baking furnace 20 with one sensor (lower temperature sensor 43 or upper temperature sensor 44). Even in such a configuration, technical actions and effects substantially the same as those described above can be obtained.

[0090] Furthermore, in the oven cooking apparatus 10 of this embodiment, power supply to the lower and upper heaters 41 and 42 is started in each power-on process of steps 12, 17, and 23 of the main control process (FIG. 8), and the monitoring timer process (FIG. 16) is started by each monitoring timer start process of steps 13, 18, and 24 immediately after that, and the algorithm is configured to monitor the non-operation time in the normal operation process (S100), reservation operation process (S19), and doucon interlock process (S170) after power-on. However, it is not limited to this. For example, the monitoring timer process (FIG. 16) is started immediately before the start of preheating (S201) of the manual operation process (S200) executed in the normal operation process (S100), reservation operation process (S19), or doucon interlock process (S170), or immediately before starting preheating in the program operation process (S300'), and the algorithm may be configured to monitor the time (non-operation time) when there is no operation such as pressing the home button 53 or doucon input in the manual operation process (S200) or program operation process (S300'). Even in such a configuration, technical actions and effects substantially the same as those described above can be obtained.
