Hereinafter, embodiments of the present invention will be described. Unless otherwise specified, the device configuration, control processing, etc. described below are not intended to be limited thereto, but are merely explanatory examples. The drawings are used to illustrate the technical features that can be adopted by the present invention.

The structure of the stove 1 will be described with reference to FIG. The stove 1 is a built-in stove. A top plate 3 is installed on the upper surface of the stove 1. In the top plate 3, the right stove burner 4 (hereinafter referred to as right stove 4) is in front of the right side, the left stove burner 5 (hereinafter referred to as left stove 5) is in front of the left side, and the back stove burner 6 is in the center back side. (Hereinafter referred to as the back stove 6) is provided. In 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. At the rear portion of the top plate 3, an exhaust port 7 of a grill storage (not shown) installed in the stove 1 is provided.

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

On the display unit 22, the right stove 4, the left stove 5, the back stove 6, the number of times the stove has been used so far, the location of the heating unit used last time, the usage time (combustion time), etc. Is displayed (see FIG. 7). Various information displayed on the display unit 22 is basically displayed in two colors, black and white, but as described later, by displaying a specific part in red, the user can pay attention to that part. Can be done. The specific display contents of the display unit 22 will be described later.

A power button 25 is provided on the upper right portion of the front surface 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 the grill burner, the operation knob 13 is the back stove 6, and the operation knob 14 is the left stove 5. The operation knobs 11 to 14 are almost flush with the front surface 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) allows the operation knobs 11 to 14 to be moved from the front surface of the stove 1. It protrudes in a substantially columnar shape toward the front, 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. The valve mechanism portion 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 portion 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 portion 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.

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, press and hold the power button 25 for 3 seconds or longer to release 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 comprehensively controls various operations of the stove 1. The ROM 72 stores various programs such as a display control program. The display control program executes the display control process (see FIG. 5) 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 thermista input circuit 82, a thermocouple input circuit 83, an igniter circuit 84, an operation panel 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 battery 17 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 circuit 81 cuts off the power supply to the various circuits, so that the power 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 panel 24 is housed in a lower right portion of the front panel of the stove 1, and is pulled out toward the front side by pushing the portion. The operation panel 24 accepts input operations such as timer setting by the user and selection of thermal power control according to the cooking menu, 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 unit 22 based on the control signal from the CPU 71. The sensor 19 is provided on each of the operation knobs 11 to 14, detects the rotation direction and the rotation angle of the operation knobs 11 to 14, and inputs 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 power information storage area 742, a usage history information storage area 743, a usage count 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 usage history information storage area 743 stores the usage history information 75, which will be described later. The number-of-use storage area 744 stores the number of times of use for each heating unit.

The usage history information 75 will be described with reference to FIG. The usage history information 75 is information on the usage history of the four heating units in the stove 1. The usage history information 75 includes various information such as a history No., a place, and a burning time for each use of the heating unit. The history No. is given every time the heating unit is used. The location is the location of the heating section used. The burning time is the burning time of the heated part used. The combustion time from ignition to extinguishing of the heating unit is recorded according to the use of each of the heating units, and both the locations of the heating units are stored in the usage history information 75 as the usage history information 75.

The display 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 display control program from the ROM 72 and executes this process.

The CPU 71 determines whether or not the initialization operation has been accepted (S11). The initialization operation is an operation of erasing the caution mark 911 (FIG. 7 (2)) and the caution message displayed on the display unit 22. The caution mark 911 and the caution message are indications prompting maintenance of a specific heating unit. The initialization operation is performed on the operation panel 24. If there is no initialization operation (S11), the CPU 71 determines whether or not the history display operation has been accepted (S21). When the user wants to confirm the usage history of the stove 1 so far, the user performs a history display operation on the operation panel 24. The history display will also be described later.

When the history display operation is not accepted (S21: NO), the CPU 71 determines whether or not there is an ignited heating unit (S14). The CPU 71 determines the presence or absence of an ignited heating unit based on the detection signal from the thermocouple 50. When there is no ignited heating unit (S14: NO), the CPU 71 determines whether or not the power has been turned off by the user (S20). If the power is not turned off (S20: NO), the CPU 71 returns to S11.

When there is an ignited heating unit (S14: YES), the CPU 71 identifies the location of the ignited heating unit based on the detected value from the thermocouple 50 (S15), and uses a timer (not shown) to burn the combustion time. The measurement of (S16) is started. Next, the CPU 71 determines whether or not there is a fire-extinguished heating unit (S17). If there is no extinguished heating unit (S17: NO), the CPU 71 returns to S11. When there is a heating unit whose fire has been extinguished (S17: YES), the CPU 71 executes a display process (S18).

The display process will be described with reference to FIG. The CPU 71 identifies the location of the extinguished heating unit based on the detection signal from the thermocouple 50 (S31). The CPU 71 ends the measurement of the combustion time of the extinguished heating unit (S32). The CPU 71 assigns a history number as a usage history of the extinguished heating unit in ascending order, and stores the location of the extinguished heating unit and the measured combustion time in the non-volatile memory 74 as the usage history information 75 (S33).

The CPU 71 calculates the number of times of use so far for each heating unit based on the usage history information 75 stored in the non-volatile memory 74 (S34). The CPU 71 temporarily stores the calculated number of times of use in the number of times of use storage area 744 of the non-volatile memory 74, and creates graph information 91 based on the stored number of times of use. As shown in FIG. 7 (1), the CPU 71 displays the created graph information 91 on the left side of the display unit 22 (S35). The graph information 91 shows, in order from the right, the number of times the right stove, the back stove, and the left stove have been used so far by a numerical value and a bar graph.

The CPU 71 displays the combustion time of the extinguished heating unit as the previous usage information 92 on the right side of the display unit 22 (S36). Further, the CPU 71 displays a stove pattern 921 showing the location of the heating portion of the stove 1 below the previous usage information 92, and highlights the extinguished heating portion in red (S37). Note that FIG. 7 (1) shows the display unit 22 when the right stove 4 is extinguished. At this time, "3 minutes 25 seconds", which is the burning time of the right stove 4, is displayed, and below that, the right stove portion of the stove pattern 921 is displayed in red (indicated in bold in the figure).

Next, the CPU 71 refers to the usage history information 75 and determines whether or not there is a heating unit whose number of uses has reached a predetermined number of times (S38). The specified number of times is set for each heating unit, and it is preferable to set the number of times for which maintenance is desirable (for example, every 100 times). When there is no heating unit that has reached the specified number of times (S38: NO), the CPU 71 proceeds with the process to S41 described later.

On the other hand, when there is a heating unit whose number of uses has reached the specified number of times (S38: YES), as shown in FIG. 7 (2), the CPU 71 has reached the specified number of times in the graph information 91 displayed on the display unit 22. A caution mark 911 is displayed and emphasized on the heating unit (S39), and a caution message "Please perform maintenance on the right stove" is displayed below the display unit 22 (S40). As a result, the user who sees the display unit 22 can quickly recognize that the maintenance of the right stove 4 is necessary.

Next, the CPU 71 calculates the usage ratio (%) of each of the right stove 4 and the left stove 5 on the upper surface of the top plate 3 (S41). For example, when both the right stove 4 and the left stove 5 are high-heat burners, there may be a large difference in the usage ratio depending on the installation environment of the stove 1 and the preference of the user. From the viewpoint of the durability of the stove 1, it is desirable that the ratio of each of the right stove 4 and the left stove 5 is equal. Therefore, the CPU 71 determines whether or not the difference in the calculated usage ratio is equal to or greater than the threshold value (S42). The threshold is, for example, 50%, but can be freely changed.

When the difference in the usage ratio is equal to or greater than the threshold value (S42: YES), the CPU 71 displays and highlights the guide mark 912, which is an arrow, on the heating portion having the smaller usage ratio in the graph information 91 (S45). ), A guide message "It is recommended to use the left stove" is displayed on the lower side of the display unit 22 (S46). As a result, the user who sees the display unit 22 can recognize that the right stove 4 is preferentially used among the right stove 4 and the left stove 5, so that the usage ratio is equalized from the next time onward. , The left stove 5 can also be used.

When the difference in the usage ratio is less than the threshold value (S42: NO), the CPU 71 determines whether or not the graph information 91 is being highlighted by the guide mark 912 (S43). If it is not highlighted (S43: NO), the CPU 71 ends this process and proceeds to S19, which will be described later in the display control process of FIG. When highlighted (S43: YES), the CPU 71 erases the guide mark 912 and the guide message to cancel the highlighting (S44). The CPU 71 ends this process, and proceeds to S19, which will be described later, in the display control process of FIG.

Returning to FIG. 5, after the display processing is completed (S18), the CPU 71 determines whether or not there is a heating unit during combustion (S19). When there is a heating portion during combustion (S19: YES), the CPU 71 returns to S17 and repeats the above process. When there is no heating unit during combustion (S19: NO), the CPU 71 determines whether or not the power is turned off (S2). When the power is turned off (S20: YES), the CPU 71 ends this process.

In the graph information 91 displayed on the display unit 22, the bar graph extends upward according to the number of times of use. Therefore, as shown in FIG. 8 (2), the most frequently used number of times is a predetermined number of times (for example, 100 times). Each time the graph is exceeded, the scale of the number of times of use, which is the vertical axis, may be changed so that the entire four graphs are displayed.

Further, as shown in FIG. 7 (2), when the caution mark 911 is displayed on the right stove 4 of the graph information 91, the user cleans the right stove 4. After cleaning, the user needs to turn on the power and erase the caution mark 911 and the caution message displayed on the display unit 22. Therefore, the user performs an initialization operation on the operation panel 24 in order to cancel the highlighting of these maintenances. As shown in FIG. 5, when the CPU 71 accepts the initialization operation (S11: YES), the maintenance highlighting is canceled by erasing the caution mark 911 and the caution message (S12). As a result, the user can erase the caution mark 911 and the caution message displayed on the display unit 22. Hereinafter, the CPU 71 executes the above process.

In addition, the user may want to check the past usage history of the stove 1. In that case, the user performs a history display operation on the operation panel 24. As shown in FIG. 5, when the history display operation is accepted on the operation panel 24 with the power of the stove 1 turned on (S11: NO, S21: YES), the CPU 71 stores the usage history information of the non-volatile memory 74. The usage history information 75 (see FIG. 4) is read out from the area 743 and displayed on the display unit 22 as shown in FIG. 9 (S22). At this time, if the usage history information 75 does not fit on the screen of the display unit 22, it may be divided and displayed, or it may be scrolled. By confirming the usage history information 75 displayed on the display unit 22, the user can grasp the usage status of the heating unit used so far in more detail. The CPU 71 determines whether or not the power is turned off (S20), and if the power is on (S20: NO), returns to S11 and repeats the above process.

As described above, in the stove 1 of the present embodiment, the graph information 91 and the previous usage information 92 are displayed on the display unit 22. Since the display unit 22 is an electronic paper, the display content is maintained without power consumption even after the power is turned off. As a result, the user can easily grasp the past usage status of the stove 1 for each heating unit by checking the graph information 91 displayed on the display unit 22 and the previous usage information 92 before turning on the power. can.

Since the graph information 91 shows the number of times of use for each heating unit so far as a bar graph, the user can instantly recognize the number of times of use for each heating unit. Further, since the bar graph is shown, the user can easily grasp the magnitude of the frequency of use with an image, so that the heating unit of the stove 1 can be appropriately used so that the frequency of use is even. Thereby, this embodiment can improve the durability of the stove 1.

Further, when the power is off, the previous usage information 92 is displayed on the display unit 22, so that, for example, when the right stove 4 is used most recently, the surroundings of the right stove 4 are still hot without being cooled. It may be. When the power is off, all the heating parts are extinguished, so you cannot tell by just looking at the heating parts, but by checking the previous usage information 92 displayed on the display unit 22, you used it last time. You can grasp the location of the heating part. Further, in the present embodiment, the previously used heating portion of the stove pattern 921 is displayed in red, so that the previously used heating portion can be intuitively recognized. As a result, it is possible to be careful not to touch the heating part used last time.

In addition, some users of the stove 1 use the right stove 4, the left stove 5, and the back stove 6, but do not want to use the grill. In this case, the user can easily recognize that the grill is not used by checking the graph information 91 displayed on the display unit 22.

As described above, the stove 1 of the present embodiment is battery-powered and includes a plurality of heating units for heating the food to be cooked. The plurality of heating units are a right stove 4, a left stove 5, a back stove 6, and a grill. A display unit 22 is provided on the top plate 3 of the stove 1. The display unit 22 is 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 unit 22. The CPU 71 stores the usage history information 75. The usage history information 75 is information on the usage history of the plurality of heating units. The CPU 71 displays the graph information 91 and the previous usage information 92 on the display unit 22 based on the usage history information 75. The graph information 91 is a bar graph showing the number of times each of the plurality of heating units is used.
