(Hereinafter referred to as the back stove 6) is provided. At the center of each of the right stove 4, the left stove 5, and the back stove 6 (hereinafter collectively referred to as stoves 4 to 6), a sensor assembly 20 that abuts on the bottom of the pot and detects the temperature of the cooking pot is provided. Be done. The sensor assembly 20 is provided so as to be able to move in and out in the vertical direction, and houses the thermistor 40 (see FIG. 2). A thermocouple 50 (see FIG. 2) for detecting a misfire and an ignition electrode (not shown) of an igniter 60 (see FIG. 2) for igniting are provided in the vicinity of each of the stoves 4 to 6. An exhaust port 7 of a grill storage (not shown) installed in the stove 1 is provided at the rear portion of the top plate 3.

On the upper surface of the top plate 3, a pair of left and right display units 22 and 23 having a substantially rectangular shape in a plan view are provided on the central front side between the right stove 4 and the left stove 5. The display units 22 and 23 are electronic papers, which can hold the displayed contents and can be electrically updated. The electronic paper of the present embodiment adopts a well-known microcup (registered trademark) method of displaying with three-color electronic ink, but other than this method, for example, Advanced Color ePaper (registered trademark) capable of displaying colors is adopted. You may. In addition to color, electronic paper capable of displaying monochrome in two colors, white and black, may be used.

Information and the like for customization settings, which will be described later, are displayed on the display unit 22 on the left side (see FIG. 9). Information indicating the completion or incompleteness of the automatic function, which will be described later, is displayed on the display unit 23 on the right side (see FIGS. 10 to 12). The various information displayed on the display units 22 and 23 is basically displayed in two colors, black and white, but as described later, by displaying a specific part in red, that part can be displayed to the user. It can be noticed. The specific display contents of the display units 22 and 23 will be described later.

A power button 25 is provided at the upper right portion of the front surface 15 of the stove 1 and directly above the operation knob 11 described later. By pressing the power button 25, the power of the stove 1 is turned on or off. A grill door 8 is provided at substantially the center of the front surface of the stove 1. The grill door 8 is movably supported toward the front side, and opens and closes an opening on the front side of the grill storage (not shown) provided inside the stove 1. A grill burner (not shown) is provided in the grill chamber. Ignition electrodes for the thermocouple 50 and the igniter 60 are also provided in the vicinity of the grill burner. In the area on the right side of the grill door 8, in order from the right side to the left side, front view circular operation knobs 11 and 12 are provided side by side in a horizontal row. Also in the area on the left side of the grill door 8, operation knobs 13 and 14 having the same circular shape are provided at the same height positions as the operation knobs 11 and 12.

The operation knob 11 is pressed to ignite or extinguish the right stove 4, the operation knob 12 is pressed to ignite or extinguish the grill burner, the operation knob 13 is pressed to ignite or extinguish the back stove 6, and the operation knob 14 is pressed to ignite or extinguish the left stove 5. The operation knobs 11 to 14 are substantially flush with the front surface 15 of the stove 1 when the corresponding burner is extinguished (see FIG. 1). When pressed for ignition, the control circuit 70 described later executes ignition processing for the corresponding burner, and a known push-push mechanism (not shown) causes the operation knobs 11 to 14 to be moved from the front surface of the stove 1. It protrudes forward in a substantially columnar shape, and the rotation operation is possible in the protruding state. When the operation knobs 11 to 14 are rotated, the control circuit 70 adjusts the gas supply amount to the corresponding burner so that the gas amount corresponds to the rotation operation amount.

Inside the stove 1, four gas amount adjusting mechanisms 30 (see FIG. 2) are provided. The gas amount adjusting mechanism 30 adjusts the gas supply amount to the corresponding stoves 4 to 6 and the grill burner. The gas amount adjusting mechanism 30 includes a valve mechanism portion 31 and a motor 32 (see FIG. 2). The valve mechanism 31 includes various valves such as a needle valve and a solenoid valve that adjust the amount of gas flowing through the gas flow path, for example. The motor 32 drives the valve of the valve mechanism unit 31 to adjust the gas flow rate flowing through the gas flow path. The drive of the motor 32 is controlled by the control circuit 70.

When the operation knobs 11 to 14 are pushed in and projected toward the front, the control circuit 70 energizes the motor 32 of the gas amount adjusting mechanism 30. As a result, the valve mechanism portion 31 is driven and the gas flow path is opened, so that gas is supplied to the corresponding burner. Then, the control circuit 70 rotates the motor 32 in the forward and reverse directions according to the rotation direction and the rotation angle of the operation knobs 11 to 14, and adjusts the opening degree of the valve in the valve mechanism portion 31. As a result, the amount of gas flowing through the gas flow path is adjusted, so that the thermal power of the corresponding burner is adjusted. Further, when the operation knobs 11 to 14 are pushed into the stove 1 and accommodated, the control circuit 70 rotates the motor 32 in the reverse direction. As a result, the valve of the valve mechanism unit 31 is driven in the opposite direction, and the gas flow path is closed, so that the supply of gas to the corresponding burner is cut off.

On the front surface 15, a panel 16 is provided below the right operation knobs 11 and 12, and a panel 17 is provided below the left operation knobs 13 and 14. When the panel 16 is pushed in with a finger, the operation unit 24A (see FIG. 2) fixed to the back surface of the panel 16 is rotated forward from the lower part and pulled out by a well-known push-on / push-off mechanism (not shown). Is done. When the panel 17 is pushed in with a finger, the operation unit 24B (see FIG. 2) fixed to the back surface of the panel 17 is rotated forward and pulled out from the lower part by the same mechanism. By pushing the panels 16 and 17 back toward the housing 2, the operation units 24A and 24B are housed in the housing 2, and the panels 16 and 17 are flush with the front surface 15.

The operation unit 24A can set the automatic functions of the right stove 4 and the grill. The operation unit 24B can set the automatic functions of the left stove 5 and the back stove 6. The automatic function is a function that automatically heats using a heating unit. For example, an automatic cooking function that automatically controls the heating temperature according to the type of cooking during cooking, and a built-in timer for a predetermined time. It has a timer function that automatically extinguishes the gas burner when it is determined that it has passed, a temperature keeping function that keeps the heating temperature at a constant temperature, and a boiling function that performs boiling. The automatic function differs for each heating unit. The types of automatic functions that can be set for each heating unit will be described later. In the following description, when the operation units 24A and 24B are collectively referred to, they are referred to as "operation unit 24".

When the power button 25 is pressed and held for 3 seconds or longer while the power of the stove 1 is on, the child lock is set. When the child lock is set, the child lock mechanism (not shown) provided inside the stove 1 is activated, and the operation knobs 11 to 14 cannot be operated. Since the child lock mechanism is well known, the description thereof will be omitted. The child lock limits the ignition operation of each stove 4-6 and the grill burner. With the child lock set, pressing and holding the power button 25 for 3 seconds or longer releases the child lock.

The electrical configuration of the stove 1 will be described with reference to FIG. The stove 1 includes a control circuit 70. The control circuit 70 includes a CPU 71, a ROM 72, a RAM 73, a non-volatile memory 74, and the like. The CPU 71 controls various operations of the stove 1 in an integrated manner. The ROM 72 stores various programs such as a heating control program and a display control program. The heating control program is a program that executes a heating control process (see FIG. 6) described later. The display control program is a program that executes display control processing (see FIGS. 7 and 8) described later. The RAM 73 temporarily stores various types of information. The non-volatile memory 74 stores various data described later.

The control circuit 70 includes a power supply circuit 81, a thermistor input circuit 82, a thermocouple input circuit 83, an igniter circuit 84, an operation unit 24, a motor control circuit 85, a child lock control circuit 86, an audio output circuit 87, a buzzer circuit 88, and a display. The control circuit 89, the sensor 19, and the like are electrically connected to each other. When the power button 25 is pressed by the user, the power circuit 81 supplies the electric power supplied from the dry cell 18 to various circuits, so that the power of the stove 1 is turned on. When the power button 25 is pressed again by the user, the power supply circuit 81 cuts off the power supply to the various circuits, so that the power supply of the stove 1 is turned off.

The thermistor input circuit 82 inputs a detection signal from the thermistor 40 stored in the sensor assembly 20 provided in each burner to the control circuit 70. The thermocouple input circuit 83 inputs the detection value (signal corresponding to the thermoelectromotive force) from the thermocouple 50 to the control circuit 70. The igniter circuit 84 drives the igniter 60 of the corresponding burner based on the control signal from the CPU 71. The operation unit 24 receives an input by the user and inputs the input signal to the control circuit 70. The motor control circuit 85 controls the driving of the motors 32 of the four gas amount adjusting mechanisms 30 based on the control signals from the CPU 71. The child lock control circuit 86 controls the drive of the child lock mechanism based on the control signal from the CPU 71.

The voice output circuit 87 converts a digital voice signal into an analog signal based on the control signal from the CPU 71, and outputs the digital signal to the speaker 77. The buzzer circuit 88 drives the piezoelectric buzzer 78 based on the control signal of the CPU 71. The display control circuit 89 displays various information described later on the display units 22 and 23 based on the control signal from the CPU 71. The sensors 19 are provided on the operation knobs 11 to 14, respectively, detect the rotation direction and the rotation angle of the operation knobs 11 to 14, and input the detection signal to the control circuit 70. Based on the detection signal from the sensor 19, the CPU 71 rotates the output shaft of the motor 32 so as to correspond to the rotation direction and the rotation angle of the operation knobs 11 to 14 to drive the valve mechanism unit 31. As a result, the amount of gas flowing through the gas flow path is adjusted, and the thermal power of the corresponding burner is adjusted.

The gas amount adjusting mechanism 30 is provided with a position sensor 35. The position sensor 35 detects the rotation angle of the output shaft of the motor 32 and inputs the detection signal to the control circuit 70. Since the CPU 71 can recognize the rotation angle of the output shaft of the motor 32 based on the detection signal from the position sensor 35, the corresponding burner thermal power can be specified by referring to the burner thermal power information stored in the non-volatile memory 74.

Various storage areas of the non-volatile memory 74 will be described with reference to FIG. The non-volatile memory 74 includes a parameter storage area 741, a thermal information storage area 742, an automatic function table storage area 743, a customized table storage area 744, and the like. The parameter storage area 741 stores various parameters such as temperature control. The thermal power information storage area 742 stores various data such as burner thermal power information. The burner thermal power information is information in which the rotation angle of the output shaft of the motor 32 is associated with the burner thermal power. In the present embodiment, the thermal power from small to large is divided into 10 stages from 1 to 10, and the rotation angle of the motor 32 is assigned to each stage. Thereby, the CPU 71 can specify the corresponding burner thermal power based on the rotation angle of the output shaft of the motor 32. The automatic function table storage area 743 stores the automatic function table 7431 (see FIG. 4) described later. The customized table storage area 744 stores the customized table 7441 (see FIG. 5) described later.

The automatic function table 7431 will be described with reference to FIG. The automatic function table 7431 stores an automatic function type that can be set for each heating unit and an automatic flag indicating whether or not each automatic function is currently being executed. The automatic functions that can be set on the right stove 4 and the left stove 5 are boiling, boiling water, temperature keeping, high temperature frying, and timer. Boil is a function that reduces the heat when it boils and adjusts the heat when the temperature drops to maintain a temperature of around 100 ° C, and automatically extinguishes the fire when the set time elapses. The water heater is a function that notifies you with a buzzer when the water boils and automatically extinguishes the fire. It is also possible to set the heat retention to 90 minutes (in 1-minute increments) after boiling. Temperature keeping is a function of keeping the temperature of oil constant in any of seven stages (140 to 200 ° C.). High-temperature stir-fry is a function of cooking at a higher temperature than usual while repeating high and low heat. If the temperature becomes too high, the fire will be extinguished automatically for safety. The timer is a function that notifies with a buzzer when the set time has elapsed and automatically extinguishes the fire.

The automatic functions that can be set on the back stove 6 are cooking, porridge, rice, and simmering fire. Takikomi gohan, rice porridge, and rice are rice cooking functions, and one of them can be selected. The heating power and heating time are automatically controlled according to the type of rice cooked selected. Melting fire is a function to hold the weakest fire (melting fire).

The automatic functions that can be set on the grill are toast, warming, grilled fish, dried fish, and fillets. Toast is a function that automatically bake bread by setting the degree of baking. Warming is a function to warm cold ingredients. Figure-grilled fish, dried fish, and fillets are the types of fish. It is a function to automatically bake by selecting one of these and setting the degree of baking.

The automatic flag is a flag set in the heating control process (see FIG. 6) described later, and 1 is stored in the automatic function currently being executed and 0 is stored in the automatic function that is not currently being executed.

The customization table 7441 will be described with reference to FIG. On the stove 1, the operating specifications can be customized within a predetermined range. The customization table 7441 stores customizable adaptive functions and their initial settings and current settings, respectively. Adaptation functions include a stove forgetting function, a range hood interlocking function, a rice cooking function, a water heater function, an auto menu function, and a thermal power switching notification function. With the stove forgetting function, the time until the fire is automatically extinguished on the right stove 4, the left stove 5, and the back stove 6 can be changed. The initial setting is "120 minutes". With the range hood interlocking function, it is possible to change the stove 1 side so that the kitchen range hood (not shown) is not interlocked. The initial setting is "linked". With the rice-cooking function, you can change the cooking time so that it is cooked to the desired hardness and degree of charring. The default setting is the standard "3" and can be adjusted in 5 steps. With the water heater function, you can change the timing of the boiling notification buzzer. The default setting is the standard "3" and can be adjusted in 5 steps. With the auto menu function, you can change the degree of grilling of the grill's automatic function so that it can be adjusted more finely. The initial setting is 3 steps and can be adjusted up to 5 steps. The thermal power switching notification function can turn off the buzzer sound that notifies when the thermal power automatically increases. The default setting is "with sound".

The heating control process will be described with reference to FIG. When the user presses the power button 25 and the power of the stove 1 is turned on, the CPU 71 reads the heating control program from the ROM 72 and executes this process. The CPU 71 initializes the automatic flags to all 0s (S1). The CPU 71 determines whether or not the ignition operation has been accepted (S2). In the ignition operation, when the ignition operation is not accepted by the operation knobs 11 to 13 (S2: NO), the CPU 71 determines whether or not the power is turned off (S12). If the power is not turned off (S12: NO), the CPU 71 returns to S2 and continues to monitor the ignition operation of the operation knobs 11 to 14.

When the ignition operation is accepted (S2: YES), the CPU 71 ignites the burner of the heating unit that has been ignited (S3). The CPU 71 determines whether or not the automatic function is set in the ignited heating unit (S4). When the automatic function is not set (S4: NO), the CPU 71 holds the combustion of the burner in the heating unit and determines whether or not there is a fire extinguishing operation (S9). If there is no fire extinguishing operation (S9: NO), the CPU 71 returns to S4 and repeats the above process.

When the automatic function is set (S4: YES), the CPU 71 determines whether or not the automatic function is being executed (S5). If it is not executed (S4: NO), the CPU 71 starts the set automatic function (S6). The CPU 71 sets the automatic flag of the automatic function of the heating unit that has started execution to 1 in the automatic function table 7431 (see FIG. 4) (S7). The CPU 71 determines whether or not the automatic function is completed (S8). When the automatic function is not completed (S8: NO), the CPU 71 determines whether or not the fire extinguishing operation has been performed (S13). If there is no fire extinguishing operation (S13: NO), the CPU 71 returns to S4.

If the automatic function is set (S4: YES) and the automatic function is being executed (S5: YES), the CPU 71 redetermines whether or not the automatic function is completed (S8). When the automatic function is completed (S8: YES), the CPU 71 extinguishes the burner (S10) and returns the corresponding automatic flag to 0 (S11). In addition, among the plurality of automatic functions, there is one that continues the combustion of the burner after the automatic function is completed. In that case, the CPU 71 may hold the combustion of the burner and proceed to S9.

Here, it is assumed that, for example, the heating unit is extinguished by spilling from the pot while the automatic function is being executed, or another person accidentally extinguishes the heating unit and leaves. If there is a fire extinguishing operation during execution of the automatic function (S8: NO, S13: YES), the CPU 71 interrupts the automatic function and extinguishes the corresponding burner (S14). The CPU 71 stores the remaining information of the interrupted automatic function in the RAM 73 (S15). The remaining information is progress information of the interrupted automatic function, for example, the state of the automatic function at the time of interruption, the estimated remaining time from the time of interruption to the completion, and the like. Next, the CPU 71 sets the corresponding automatic flag to 0 (S11). The CPU 71 determines whether or not the power is turned off (S12), and if the power is turned off (S12: YES), ends this process.

The display control process will be described with reference to FIGS. 7 and 8. When the user presses the power button 25 and the power of the stove 1 is turned on, the CPU 71 reads the display control program from the ROM 72 and executes this process. The CPU 71 initializes and erases the displays of the display units 22 and 23 (S21). The CPU 71 determines whether or not the customize mode is set (S22). When the user wants to change the operating specifications of the stove 1, the user sets the customization mode on the operation unit 24. When the customize mode is not set (S22: NO), the CPU 71 advances the process to S28 (see FIG. 8) described later.

When the customize mode is set (S22: YES), the CPU 71 displays the operation specification information 221 on the display unit 22 based on the customization table 7441 (see FIG. 4) as shown in FIG. 9 (S23). The user confirms the current setting by looking at the operation specification information 221 displayed on the display unit 22. For example, when the user wants to change the specifications of the rice cooking function, the user can change the setting of the current specifications by moving the cursor 222 to the item of the rice cooking function on the operation unit 24.

The CPU 71 determines whether or not the operating specifications have been changed (S24). When changed (S24: YES), the CPU 71 updates the operation specification information 221 displayed on the display unit 22 (S25). The CPU 71 determines whether or not the customization mode setting is completed (S26). If the setting is not completed (S26: NO), the CPU 71 returns to S24 and repeats the above process. When the setting of the customize mode is completed (S26: YES), as shown in FIG. 8, the CPU 71 determines whether or not there is a heating portion during combustion in the stove 1 (S28).

When there is no heating unit during combustion (S28: NO), the CPU 71 determines whether or not the power is turned off (S37). If the power is not turned off (S37: NO), the CPU 71 returns to S22 in FIG. 7 and repeats the above process. When there is a heating unit during combustion (S28: YES), the CPU 71 refers to the automatic function table 7431 (see FIG. 4) and determines whether or not there is a heating unit during automatic function execution (S29). If the automatic flags are all 0 and there is no heating unit during automatic function execution (S29: NO), the CPU 71 returns to S22 in FIG. 7 and repeats the above process unless the power is turned off (S37: NO).

With reference to the automatic function table 7431, if there is a heating unit having an automatic flag of 1, since there is a heating unit in which the automatic function is being executed (S29: YES), the CPU 71 determines whether or not the burner of the heating unit has been extinguished. Judgment (S30). When the fire is not extinguished (S30: NO), the CPU 71 returns to S29 and repeats the above process. When the fire is extinguished (S30: YES), the CPU 71 specifies the location of the extinguished heating unit (S31). The CPU 71 determines whether or not the automatic function of the specified heating unit is normally completed (S32). Whether or not the automatic function is normally completed may be determined, for example, by whether or not the remaining information of the heating unit corresponding to the RAM 73 is stored.

When the automatic function is normally completed (S32: YES), the CPU 71 displays the completion information 231 on the display unit 23 (S35), as shown in FIG. Completion information 231 includes the location of the heating unit, the type of automatic function, the completion message, and the like. As an example of the completion message, for example, "The automatic function (water heater) has been completed." May be used. In addition, by adding "○" in front of the completion message, it is possible to intuitively recognize that the automatic function is successful. By visually recognizing the completion information 231 displayed on the display unit 23, the user can grasp that the automatic function has been completed normally. In addition to this, when the automatic function (rice) of the back stove 6 is completed, the CPU 71 adds the completion information 232 to the display unit 23 and displays it below the completion information 231 as shown in FIG.

When the automatic function is interrupted for some reason and the fire is extinguished in an incomplete state (S32: NO), the CPU 71 reads the remaining information stored in the RAM 73 (S33) and the display unit 23 is incomplete. Information 233 is displayed in red (S35). For example, if the automatic function (water heater) of the right stove 4 is completed normally, but the fire is extinguished before the automatic function (rice) of the back stove 6 is completed, as shown in FIG. 12, the CPU 71 is in the back. The incomplete information 233 of the stove 6 is displayed on the display unit 23. The incomplete information 233 includes the location of the heating unit, the type of the automatic function, the incomplete message, the remaining time until completion, and the like. As an example of the incomplete message, for example, "The fire was extinguished before the automatic function (rice) was completed." In addition, by adding an "x" in front of the incomplete message, it is possible to intuitively recognize that the automatic function has failed. The remaining time is displayed below the incomplete message and may be displayed as an estimated remaining time to complete. Since these incomplete information 233 are displayed in red, it is possible to strongly impress the user that the automatic function is in an incomplete state.

By visually recognizing the incomplete information 233 displayed on the display unit 23, the user can recognize that the fire has been extinguished before the automatic function is completed. Furthermore, by checking the remaining time, it is possible to grasp to what stage the automatic function has progressed. For example, in the case of the automatic function (rice), it is possible to grasp to what stage the rice cooking has progressed. For example, if it is interrupted in the steaming process, it may be steamed as it is, and if it is interrupted in the initial process, rice cooking can be tried again. In this way, by grasping to what stage the automatic function has progressed, it can be used as a guide for subsequent measures.

The CPU 71 determines whether or not there is a heating unit during automatic function execution (S36). If there is a heating unit during automatic function execution (S36: YES), the CPU 71 returns to S30 and repeats the above process. When there is no heating unit during automatic function execution (S36: NO), the CPU 71 determines whether or not the power is turned off (S37). When the power is turned off (S37: YES), the CPU 71 ends this process.

As described above, in the stove 1 of the present embodiment, when the automatic function is set and used, the completion information 231 is displayed on the display unit 23 when the automatic function is completed, and the fire is extinguished in an incomplete state. In that case, the incomplete information 233 is displayed on the display unit 23. Since the display unit 23 is an electronic paper, the display content is retained without power consumption even after the power is turned off. As a result, even when the power is off, the user can grasp whether or not the automatic function is normally completed by checking the completion information 231 or the incomplete information 233 displayed on the display unit 23. Therefore, the user can take appropriate measures such as reheating the food to be cooked for which the automatic function has not been completed.

Further, in the stove 1 of the present embodiment, the operation specification information 221 is displayed on the display unit 22 by setting the customize mode. Since the display unit 22 is also electronic paper, the display content is retained without power consumption even after the power is turned off. As a result, the user can easily grasp the operating specifications currently set on the stove 1 even when the power is off.

As described above, the stove 1 of the present embodiment is battery-powered and includes an operation unit 24 for setting the operation mode of the stove 1 when the power is turned on. The operation mode is, for example, an automatic function set in the heating unit, an operation specification of the stove 1, and the like. Display units 22 and 23 are provided on the top plate 3 of the stove 1. The display units 22 and 23 are made of electronic paper, can hold the displayed contents, and can be electrically updated. The CPU 71 of the stove 1 displays and updates various information on the display units 22 and 23. The CPU 71 displays the state of the stove 1 whose operation mode is set by the operation unit 24 on the display units 22 and 23. Therefore, the stove 1 can continue to display the operation mode of the stove 1 without power consumption even when the power is turned off. As a result, the user can check the state of the stove 1 before turning on the power, so that the cooking can be started promptly after turning on the power.

In the above description, the operation unit 24 (24A, 24B) is an example of the "setting unit" of the present invention. The CPU 71 that executes the process of S29 in FIG. 8 is an example of the "execution determination unit" of the present invention. The CPU 71 that executes the process of S32 is an example of the "completion determination unit" of the present invention.
