[0069] (Insights etc. that form the basis of the present disclosure)

[0070] When the inventors came up with the present disclosure, there was a heating cooker that stops cooking by operating a key, like the rice cooker described in Patent Document 1. However, in a structure like the rice cooker of Patent Document 1 where cooking is immediately stopped when a key is operated, when the user accidentally operates the key, cooking is stopped inadvertently regardless of the way the key is operated. Here, in order to provide the user with a period to confirm whether the key has been intentionally operated, a structure in which cooking is not immediately stopped after the key is operated was considered, but the inventors found the following problem: During the period from when the key is operated to when cooking is stopped, it is necessary to ensure the safety of the user from actions related to the cooking of the heating cooker. To solve this problem, the subject of the present disclosure was formed.

[0071] Therefore, the present disclosure provides a heating cooker, a control method for a heating cooker, and a recording medium that can suppress the interruption of cooking inadvertently by the user while ensuring the safety of the user.

[0072] Hereinafter, the implementation mode will be described in detail with reference to the drawings. However, sometimes the description that is more detailed than necessary is omitted. For example, sometimes the detailed description of matters that are already known, or the repeated description of substantially the same structure, is omitted.

[0073] In addition, the drawings and the following description are provided for those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims by these.

[0117] [1-1-2. Structure of the screen displayed by the control unit]

[0118] Here, the screen displayed by the control unit 100 on the display 201 will be described.

[0119] In the description of the screen displayed by the control unit 100, the case where the heating cooker 1 performs normal cooking and the case where it performs pressure cooking will be described separately.

[0120] [1-1-2-1. Case of normal cooking]

[0121] Figure 5 It is a diagram showing an example of the screen displayed by the control unit 100.

[0122] In the case of performing normal cooking by the cooking unit 102, the control unit 100 displays the normal cooking screen G1 on the display 201.

[0123] The normal cooking screen G1 is a screen showing that the heating cooker 1 is performing normal cooking. The normal cooking screen G1 has a first area A1, a second area A2, a third area A3, a fourth area A4, a fifth area A5, a sixth area A6, and a seventh area A7.

[0124] The first area A1 is an area for displaying the type of dish made by the heating cooker 1 through normal cooking. Figure 5The first area A1 shows that the variety of the dish made by the heating cooker 1 through normal cooking is "Mapo Tofu" by means of string display. Additionally, the first area A1 can also display, instead of or together with the variety of the dish, the type of normal cooking (boiling, steaming, frying, heating, etc.) being performed by the heating cooker 1. Moreover, the first area A1 can display the variety of the dish not by string but by icon.

[0125] The second area A2 is the area that shows what kind of normal cooking the heating cooker 1 is performing. When the normal cooking being performed by the heating cooker 1 is cooking accompanied by the use of a stirring component, the second area A2 shows by icon that the normal cooking being performed by the heating cooker 1 is cooking using the stirring component. And when the normal cooking being performed by the heating cooker 1 is cooking accompanied by the use of a steaming plate, the second area A2 shows by icon that the normal cooking being performed by the heating cooker 1 is cooking using the steaming plate. And when the normal cooking being performed by the heating cooker 1 is boiling, the second area A2 shows by icon that the normal cooking being performed by the heating cooker 1 is boiling. Additionally, according to the type of normal cooking being performed by the heating cooker 1, the variety of the dish made through normal cooking, etc., the number of icons shown in the second area A2 can also be multiple. Moreover, the second area A2 can show what kind of normal cooking the heating cooker 1 is performing not by icon but by string.

[0126] The third area A3 is the area that shows the heating cooker 1 is performing normal cooking. Figure 5 The third area A3 of shows that the heating cooker 1 is performing normal cooking by displaying a string such as "Cooking". Additionally, the third area A3 can show that the heating cooker 1 is performing normal cooking not by string but by icon.

[0127] The fourth area A4 is the area that shows by string that the time shown in the seventh area A7 is the remaining time until the end of cooking. The remaining time until the end of cooking is the remaining time until the end of the cooking being performed by the heating cooker 1. Figure 5 The fourth area A4 of shows that the time shown in the seventh area A7 is the remaining time until the end of cooking by means of a string such as "Remaining". Additionally, the fourth area A4 can show that the time shown in the seventh area A7 is the remaining time until the end of cooking not by string but by icon.

[0128] The fifth area A5 is the area that shows how many servings of cooking the heating cooker 1 is performing. Figure 5 The fifth area A5 of shows how many servings of cooking the heating cooker 1 is performing by displaying a combination of an icon imitating a person and a number. Figure 5The fifth area A5 shows that the heating cooker 1 is performing cooking for four people. Additionally, the fifth area A5 can also show the number of people for which the heating cooker 1 is performing cooking, either only by a string or only by an icon.

[0129] The sixth area A6 is an area that shows what kind of normal cooking the heating cooker 1 is performing. When the normal cooking being performed by the heating cooker 1 is cooking accompanied by the use of a stirring member, the sixth area A6 shows by an icon that the normal cooking being performed by the heating cooker 1 is cooking using the stirring member. Also, when the normal cooking being performed by the heating cooker 1 is cooking accompanied by the use of a steaming plate, the sixth area A6 shows by an icon that the normal cooking being performed by the heating cooker 1 is cooking using the steaming plate. And, when the normal cooking being performed by the heating cooker 1 is boiling, the sixth area A6 shows by an icon that the cooking being performed by the heating cooker 1 is boiling.

[0130] The seventh area A7 is an area that indicates the remaining time until the end of cooking. The control unit 100 measures the remaining time until the end of cooking during the execution of cooking by the cooking unit 102. The control unit 100 displays the measured remaining time until the end of cooking in the seventh area A7. More specifically, in the present embodiment, when starting the cooking by the cooking unit 102, the control unit 100 starts a countdown in a prescribed unit (for example, in units of 1 second) from the cooking time specified by the cooking conditions, and measures the remaining time until the end of cooking during the execution of cooking by the cooking unit 102. The control unit 100 displays the measured remaining time until the end of cooking in the seventh area A7 at the timing when the countdown reaches 1 minute.

[0131] When the remaining time until the end of cooking is measured to be zero seconds, the control unit 100 ends the normal cooking of the cooking unit 102. When the heating cooker 1 ends the normal cooking, the control unit 100 switches the screen displayed on the display 201 from the normal cooking screen G1 to the home screen HG.

[0132] When the cancel key Ky2 is long-pressed (for example, an operation of continuously pressing for 0.4 seconds or more) while the display 201 is displaying the normal cooking screen G1, the control unit 100 switches the screen displayed on the display 201 from the normal cooking screen G1 to the normal cooking cancellation confirmation screen G2. In addition, during one cooking (from the start of cooking to the end of cooking), when the cancel key Ky2 is long-pressed four times, the control unit 100 switches the screen displayed on the display 201 from the normal cooking screen G1 to the main screen HG. That is, when the cancel key Ky2 is long-pressed, if the long-press operation is equivalent to any of the first, second, or third long-press operations during one cooking, the control unit 100 switches the screen displayed on the display 201 from the normal cooking screen G1 to the normal cooking cancellation confirmation screen G2.

[0133] In addition, these three times are an example of the "prescribed number of times".

[0134] The normal cooking cancellation confirmation screen G2 is a screen for the user to confirm the cancellation of normal cooking. The normal cooking cancellation confirmation screen G2 includes a normal cooking restart guidance screen G21 and a normal cooking cancellation guidance screen G22.

[0135] The normal cooking restart guidance screen G21 is a screen for the user to confirm the cancellation of normal cooking and is a screen that guides that normal cooking can be restarted by operating the start key Ky6.

[0136] The normal cooking restart guidance screen G21 has a first area A1, a second area A2, an eighth area A8, a ninth area A9, and a tenth area A10.

[0137] The eighth area A8 is an area for displaying a string asking whether to cancel cooking. Figure 5 The eighth area A8 of displays a string such as "Cancel cooking?".

[0138] The ninth area A9 is an area for displaying that cooking can be restarted by operating the start key Ky6. Figure 5 The ninth area A9 of displays that cooking can be restarted by operating the start key Ky6 by displaying a string such as "Restart cooking by [Start]".

[0139] The tenth area A10 is an area for displaying the remaining time for canceling cooking. The remaining time for canceling cooking is the remaining time until the heating cooker 1 cancels cooking.

[0140] The normal cooking cancellation guidance screen G22 is a screen for the user to confirm the cancellation of normal cooking and is a screen that guides that normal cooking can be canceled by operating the cancel key Ky2.

[0141] Normally, the cooking cancellation guidance screen G22 has a first area A1, a second area A2, an eighth area A8, an eleventh area A11, and a tenth area A10.

[0142] The eleventh area A11 is an area that displays that cooking can be cancelled by operating the cancel key Ky2. Figure 5 The eleventh area A11 of the displays that cooking can be cancelled by operating the cancel key Ky2 by displaying a string such as "Cancel cooking by [Cancel]".

[0143] During the period when the normal cooking cancellation confirmation screen G2 is being displayed on the display 201, the control unit 100 temporarily stops the cooking of the cooking unit 102. During this temporary stop, the control unit 100 controls the power supply unit 103 to stop the power supply to the load 115. Also, during this temporary stop, the control unit 100 also stops the counting of the remaining cooking time. In addition, the so-called temporary stop of cooking means a state in which cooking can be restarted from the time point of the temporary stop by operating the start key Ky6 described later. When starting the temporary stop of cooking, the control unit 100 outputs a sound indicating the start of the temporary stop through the sound output unit 104.

[0144] Also, when starting the temporary stop of cooking of the cooking unit 102, the control unit 100 starts counting the remaining cooking cancellation time. Specifically, when starting the temporary stop of cooking, the control unit 100 starts a countdown in units of 1 second from a predetermined specified time (for example, 15 seconds), thereby starting the counting of the remaining cooking cancellation time. Every time the specified time is counted down by 1 second, in other words, every time the remaining cooking cancellation time counted decreases by 1 second, the control unit 100 alternately switches the display between the normal cooking restart guidance screen G21 and the normal cooking cancellation guidance screen G22. Also, every time the remaining cooking cancellation time decreases by 1 second, the control unit 100 displays the remaining cooking time obtained by counting on the tenth area A10. Thus, the control unit 100 alternately switches the screens, for example, as follows: the normal cooking restart guidance screen G21 showing 15 seconds of remaining cooking cancellation time → the normal cooking cancellation guidance screen G22 showing 14 seconds of remaining cooking cancellation time → the normal cooking restart guidance screen G21 showing 13 seconds of remaining cooking cancellation time →...

[0145] In addition, in the present embodiment, the display switching interval between the normal cooking restart guidance screen G21 and the normal cooking cancellation guidance screen G22 is 1 second, but it may also be greater than 1 second or less than 1 second.

[0146] In addition, the control unit 100 can output a sound through the sound output unit 104 every time the timer counts during the countdown of the remaining time of the cooking interruption, or can output a sound through the sound output unit 104 every time the timer counts starting from a timing when the remaining time of the cooking interruption is, for example, only 5 seconds.

[0147] When the start key Ky6 is operated while the normal cooking interruption confirmation screen G2 is being displayed on the display 201, the control unit 100 switches the screen displayed on the display 201 from the normal cooking interruption confirmation screen G2 to the normal cooking screen G1. Also, when the start key Ky6 is operated while the normal cooking interruption confirmation screen G2 is being displayed on the display 201, the control unit 100 resumes the temporarily stopped cooking and also resumes the countdown of the remaining time of the stopped cooking.

[0148] When the cancel key Ky2 is operated while the normal cooking interruption confirmation screen G2 is being displayed on the display 201, the control unit 100 switches the screen displayed on the display 201 from the normal cooking interruption confirmation screen G2 to the home screen HG. Along with this switch, the control unit 100 determines the interruption of the temporarily stopped cooking and aborts the temporarily stopped cooking. Also, when the interruption of the cooking is determined, the control unit 100 outputs a sound indicating the determination of the cooking interruption through the sound output unit 104. In addition, aborting the cooking means a state where the temporarily stopped cooking cannot be resumed again, and is a state where the power supply to the load 115 is stopped and the cooking conditions referred to before the temporary stop are discarded.

[0149] When the remaining time of the cooking interruption counts down to zero seconds, the control unit 100 switches the screen displayed on the display 201 from the normal cooking interruption confirmation screen G2 to the home screen HG. Also, the control unit 100 determines the interruption of the temporarily stopped cooking and aborts the temporarily stopped cooking.

[0150] [1-1-2-2. Case of pressure cooking]

[0151] Next, the screen displayed by the control unit 100 in the case of performing pressure cooking will be described.

[0152] Figure 6 It is a diagram showing an example of the screen displayed by the control unit 100.

[0153] When pressure cooking is being performed by the cooking unit 102, the control unit 100 displays a pressure cooking screen G3 on the display 201.

[0154] During pressure cooking, the screen G3 indicates that the heating cooker 1 is performing pressure cooking. The pressure cooking screen G3 has a twelfth area A12, a thirteenth area A13, a fourteenth area A14, a fourth area A4, a fifteenth area A15, a sixteenth area A16, and a seventh area A7.

[0155] The twelfth area A12 is an area that shows the variety of dishes made by the heating cooker 1 through pressure cooking. Figure 6 The twelfth area A12 of shows that the variety of dishes made by the heating cooker 1 through pressure cooking is "stewed meat chunks" by displaying a string. Additionally, the twelfth area A12 may also show the variety of dishes not by a string but by an icon.

[0156] The thirteenth area A13 is an area that shows what kind of cooking the heating cooker 1 is performing during pressure cooking. Since the pressure cooking screen G3 indicates that pressure cooking is being performed, the thirteenth area A13 shows by an icon that the cooking being performed by the heating cooker 1 is pressure cooking. When the cooking being performed by the heating cooker 1 is a cooking that involves the use of a stirring component, the thirteenth area A13 also shows by an icon that the pressure cooking being performed by the heating cooker 1 is a cooking that uses a stirring component. Additionally, the thirteenth area A13 may also show what kind of cooking the heating cooker 1 is performing during pressure cooking not by an icon but by a string.

[0157] The fourteenth area A14 is an area that shows that the heating cooker 1 is under pressure. Figure 6 The fourteenth area A14 of shows that the heating cooker 1 is under pressure by displaying a string such as "under pressure". Additionally, the fourteenth area A14 may also show that the heating cooker 1 is under pressure not by a string but by an icon.

[0158] The fifteenth area A15 is an area that shows that the lid 11 is locked (fixed) in the closed state. Figure 6 The fifteenth area A15 of shows that the lid 11 is locked in the closed state by displaying a combination of an icon imitating a key in the locked state and a string such as "locked". Additionally, the fifteenth area A15 may also show that the lid 11 is locked in the closed state only by a string or only by an icon.

[0159] The sixteenth area A16 is an area that shows that the cooking being performed by the heating cooker 1 is pressure cooking. The sixteenth area A16 shows by an icon that the cooking being performed by the heating cooker 1 is pressure cooking. Additionally, the sixteenth area A16 may also show that the cooking being performed by the heating cooker 1 is pressure cooking not by an icon but by a string.

[0160] The control unit 100, in the same way as in normal cooking, measures the remaining cooking time while performing pressure cooking through the cooking unit 102. When the remaining cooking time reaches zero seconds, the control unit 100 ends the pressure cooking and starts decompressing the cooking space S through the cooking unit 102. During this decompression, the pressure regulating valve 182 is set to a specified opening degree, and the pressure in the cooking space S is reduced to one atmosphere. Along with the start of this decompression, the control unit 100 switches the screen displayed on the display 201 from the pressure cooking screen G3 to the first decompression screen G4.

[0161] Alternatively, the time required for decompression can be included in the remaining cooking time. In the case of this structure, when the remaining cooking time reaches zero seconds, the control unit 100 does not display the first decompression screen G4, but switches the display from the pressure cooking screen G3 to the home screen HG.

[0162] The first decompression screen G4 is a screen indicating that the pressure in the cooking space S is being decompressed. The first decompression screen G4 has a twelfth area A12, a thirteenth area A13, a fifteenth area A15, a seventeenth area A17, an eighteenth area A18, and a nineteenth area A19.

[0163] The seventeenth area A17 is an area that displays that the heating cooker 1 is in decompression. Figure 6 The seventeenth area A17 of the displays that the heating cooker 1 is in decompression by showing a string such as "in decompression". Alternatively, the seventeenth area A17 can display that the heating cooker 1 is in decompression not by a string but by an icon.

[0164] The eighteenth area A18 is an area that displays that the cooking has ended. Figure 6 The eighteenth area A18 of the displays that the heating cooker 1 has ended the cooking by showing a string such as "cooking ended". Alternatively, the eighteenth area A18 can display that the cooking has ended not by a string but by an icon.

[0165] The nineteenth area A19 is an area that displays that manual exhaust can be performed by a long press operation of the confirmation key Ky4. The nineteenth area A19 shows that manual exhaust can be performed by a long press operation of the confirmation key Ky4 by displaying a string such as "manually exhaust by long pressing [OK]".

[0166] When the decompression ends, the control unit 100 switches the screen displayed on the display 201 from the first decompression screen G4 to the home screen HG.

[0167] When the cancel key Ky2 is long-pressed (for example, an operation of continuously pressing for 0.4 seconds or more) while the pressure cooking screen G3 is being displayed on the display 201, the control unit 100 switches the screen displayed on the display 201 from the pressure cooking screen G3 to the pressure cooking cancellation confirmation screen G5. In addition, in one cooking (from the start of cooking to the end of cooking), when the cancel key Ky2 is long-pressed four times, the control unit 100 aborts the cooking and starts decompression, and switches the screen displayed on the display 201 from the normal cooking screen G1 to the second decompression screen G6. That is, when the cancel key Ky2 is long-pressed and this long-press operation is equivalent to any of the first, second, or third long-press operations in one cooking, the control unit 100 switches the screen displayed on the display 201 from the pressure cooking screen G3 to the pressure cooking cancellation confirmation screen G5.

[0168] In addition, these three times are an example of the "specified number of times".

[0169] The pressure cooking cancellation confirmation screen G5 is a screen for confirming the cancellation of pressure cooking to the user. The pressure cooking cancellation confirmation screen G5 includes a pressure cooking restart guidance screen G51 and a pressure cooking cancellation guidance screen G52.

[0170] Hereinafter, when not distinguishing between the normal cooking restart guidance screen G21 and the pressure cooking restart guidance screen G51, the label "G20" is marked and it is called the "second screen G20". And when not distinguishing between the normal cooking cancellation guidance screen G22 and the pressure cooking cancellation guidance screen G52, the label "G10" is marked and it is called the "first screen G10".

[0171] The pressure cooking restart guidance screen G51 is a screen for confirming the cancellation of pressure cooking to the user, and is a screen for guiding that pressure cooking can be restarted by operating the start key Ky6.

[0172] The pressure cooking restart guidance screen G51 has a twelfth area A12, a thirteenth area A13, an eighth area A8, a ninth area A9, and a tenth area A10.

[0173] The pressure cooking cancellation guidance screen G52 is a screen for confirming the cancellation of pressure cooking to the user, and is a screen for guiding that pressure cooking can be cancelled by operating the cancel key Ky2.

[0174] The pressure cooking cancellation guidance screen G52 has a twelfth area A12, a thirteenth area A13, an eighth area A8, an eleventh area A11, and a tenth area A10.

[0175] While the pressure cooking cancellation confirmation screen G5 is being displayed on the display 201, the control unit 100 temporarily stops the cooking of the cooking unit 102. During this temporary stop, the control unit 100 controls the power supply unit 103 to stop the power supply to the load 115. Also, during this temporary stop, the control unit 100 also stops the counting of the remaining cooking time. And when starting the temporary stop of cooking, the control unit 100 outputs a sound indicating the start of the temporary stop through the sound output unit 104.

[0176] Also, when starting the temporary stop of the cooking of the cooking unit 102, the control unit 100 starts counting the remaining cooking cancellation time. Specifically, when starting the temporary stop of cooking, the control unit 100 starts a countdown in units of 1 second from a predetermined time (for example, 15 seconds) to start counting the remaining cooking cancellation time. Every time the predetermined time is counted down by 1 second, in other words, every time the remaining cooking cancellation time obtained by counting decreases by 1 second, the control unit 100 alternately switches the display between the pressure cooking restart guidance screen G51 and the pressure cooking cancellation guidance screen G52. And every time the remaining cooking cancellation time decreases by 1 second, the control unit 100 displays the remaining cooking time obtained by counting in the tenth area A10. Thus, the control unit 100 alternately switches the screen such as the pressure cooking restart guidance screen G51 showing 15 seconds of remaining cooking cancellation time → the pressure cooking cancellation guidance screen G52 showing 14 seconds of remaining cooking cancellation time → the pressure cooking restart guidance screen G51 showing 13 seconds of remaining cooking cancellation time →...

[0177] In addition, in the present embodiment, the display switching interval between the pressure cooking restart guidance screen G51 and the pressure cooking cancellation guidance screen G52 is 1 second, but it can also be greater than 1 second or less than 1 second.

[0178] In addition, the control unit 100 can either output a sound through the sound output unit 104 every time it counts during the counting of the remaining cooking cancellation time, or start outputting a sound through the sound output unit 104 every time it counts from the timing when the remaining cooking cancellation time is only, for example, 5 seconds.

[0179] When the start key Ky6 is operated while the pressure cooking cancellation confirmation screen G5 is being displayed on the display 201, the control unit 100 switches the screen displayed on the display 201 from the pressure cooking cancellation confirmation screen G5 to the pressure cooking in progress screen G3. And when the start key Ky6 is operated while the pressure cooking cancellation confirmation screen G5 is being displayed on the display 201, the control unit 100 restarts the temporarily stopped pressure cooking and also restarts the counting of the remaining cooking time that has been stopped.

[0180] When the cancel key Ky2 is operated while the pressure cooking cancellation confirmation screen G5 is being displayed on the display 201, the control unit 100 switches the screen displayed on the display 201 from the pressure cooking cancellation confirmation screen G5 to the second pressure reduction in progress screen G6. Also, when the cancel key Ky2 is operated while the pressure cooking cancellation confirmation screen G5 is being displayed on the display 201, the control unit 100 determines the cancellation of the temporarily stopped cooking, cancels the cooking, and starts the pressure reduction. In addition, when the cancellation of the cooking is determined, the control unit 100 outputs a sound indicating the determination of the cancellation of the cooking through the sound output unit 104.

[0181] When the remaining time for cooking cancellation counts down to zero seconds, the control unit 100 switches the screen displayed on the display 201 from the pressure cooking cancellation confirmation screen G5 to the second pressure reduction in progress screen G6. Also, the control unit 100 determines the cancellation of the temporarily stopped cooking, cancels the cooking, and starts the pressure reduction.

[0182] The second pressure reduction in progress screen G6 is a screen indicating that the pressure in the cooking space S is being reduced. The second pressure reduction in progress screen G6 has a twelfth area A12, a thirteenth area A13, a fifteenth area A15, a seventeenth area A17, a twentieth area A20, and a nineteenth area A19.

[0183] The twentieth area A20 is an area for displaying the cancelled cooking. Figure 6 The twentieth area A20 of displays that the heating cooker 1 has cancelled the cooking by displaying a string such as "Cooking cancelled". Alternatively, the twentieth area A20 may display the end of cooking not by a string but by an icon.

[0184] When the pressure reduction is completed, the control unit 100 switches the screen displayed on the display 201 from the second pressure reduction in progress screen G6 to the main screen HG.

[0185] [1-2. Operations]

[0186] Next, the operations of the heating cooker 1 of the present embodiment will be described.

[0187] In the description of the operations of the heating cooker 1, the operations related to normal cooking and the operations related to pressure cooking will be described separately.

[0188] [1-2-1. Operations related to normal cooking]

[0189] First, refer to Figure 7 The operations of the heating cooker 1 related to normal cooking will be described.

[0190] Figure 7 is a flowchart showing the operations of the heating cooker 1.

[0191] When normal cooking starts through the cooking unit 102 (step SA1), the control unit 100 starts counting down the remaining time until cooking ends (step SA2). In step SA2, the control unit 100 starts counting down from the cooking time specified by the cooking conditions in a specified unit, thereby starting to count down the remaining time until cooking ends.

[0192] Next, the control unit 100 starts displaying the normal cooking screen G1 on the display 201 (step SA3).

[0193] The control unit 100 determines whether a long press operation of the cancel key Ky2 has been performed (step SA4).

[0194] When it is determined that the cancel key Ky2 has not been long pressed (step SA4: No), the control unit 100 determines whether the remaining time until cooking ends has been counted down to zero seconds (step SA5).

[0195] When it is determined that the remaining time until cooking ends has not been counted down to zero seconds (step SA5: No), the control unit 100 returns the process to step SA4 and makes the determination of step SA4 again.

[0196] When it is determined that the remaining time until cooking ends has been counted down to zero seconds (step SA5: Yes), the control unit 100 ends the cooking of the cooking unit 102 (step SA6). Then, the control unit 100 displays the main screen HG on the display 201 (step SA7).

[0197] Returning to the description of step SA4, when it is determined that the cancel key Ky2 has been long pressed for a specified period (step SA4: Yes), the control unit 100 determines whether the long press operation of the cancel key Ky2 is the fourth long press operation of the cancel key Ky2 in one cooking (step SA8).

[0198] When it is determined that the long press operation of the cancel key Ky2 is the fourth long press operation (step SA8: Yes), the control unit 100 transfers the process to step SA15 and executes the processes after step SA15.

[0199] On the other hand, when it is determined that the long press operation of the cancel key Ky2 is not the fourth long press operation (step SA8: No), the control unit 100 stops the power supply to the load 115 and temporarily stops the cooking of the cooking unit 102 (step SA9).

[0200] Next, the control unit 100 starts displaying the normal cooking suspension confirmation screen G2 on the display 201 (step SA10).

[0201] Next, the control unit 100 starts counting down the remaining time for cooking cancellation (step SA11). When a predetermined time, for example 15 seconds, is set, in step SA11, the countdown starts from 15 seconds.

[0202] The control unit 100 determines whether the start key Ky6 has been operated (step SA12).

[0203] When it is determined that the start key Ky6 has not been operated (step SA12: No), the control unit 100 determines whether the cancel key Ky2 has been operated (step SA13).

[0204] When it is determined that the cancel key Ky2 has not been operated (step SA13: No), the control unit 100 determines whether the countdown has reached zero seconds for the remaining cooking cancellation time (step SA14).

[0205] When it is determined that the countdown has not reached zero seconds for the remaining cooking cancellation time (step SA14: No), the control unit 100 returns the process to step SA12 and makes the determination of step SA12 again.

[0206] On the other hand, when it is determined that the countdown has reached zero seconds for the remaining cooking cancellation time (step SA14: Yes), the control unit 100 cancels the cooking of the cooking unit 102 (step SA15) and displays the main screen HG on the display 201 (step SA16).

[0207] Returning to the explanation of step SA12, when it is determined that the start key Ky6 has been operated (step SA12: Yes), the control unit 100 resumes displaying the normal cooking screen G1 on the display 201 (step SA17) and resumes the temporarily stopped cooking (step SA18).

[0208] Returning to the explanation of step SA13, when it is determined that the cancel key Ky2 has been operated (step SA13: Yes), the control unit 100 cancels the cooking of the cooking unit 102 (step SA15) and displays the main screen HG on the display 201 (step SA16).

[0209] [1-2-2. Operations related to pressure cooking]

[0210] First, refer to Figure 8 The operation of the heating cooker 1 related to pressure cooking will be described.

[0211] Figure 8 is a flowchart showing the operation of the heating cooker 1.

[0212] When starting pressure cooking by the cooking unit 102 (step SB1), the control unit 100 starts counting down the remaining time until cooking ends (step SB2). In step SB2, the control unit 100 starts counting down from the cooking time specified by the cooking conditions in a specified unit, thereby starting to count down the remaining time until cooking ends.

[0213] Next, the control unit 100 starts displaying the in-pressure-cooking screen G3 on the display 201 (step SB3).

[0214] Next, the control unit 100 determines whether the cancel key Ky2 is long-pressed (step SB4).

[0215] When it is determined that the cancel key Ky2 is not long-pressed (step SB4: No), the control unit 100 determines whether the countdown reaches zero seconds for the remaining time until cooking ends (step SB5).

[0216] When it is determined that the countdown does not reach zero seconds for the remaining time until cooking ends (step SB5: No), the control unit 100 returns the process to step SB4 and makes the determination in step SB4 again.

[0217] When it is determined that the countdown reaches zero seconds for the remaining time until cooking ends (step SB5: Yes), the control unit 100 ends the pressure cooking of the cooking unit 102 and starts decompression (step SB6).

[0218] Next, the control unit 100 displays the first-in-decompression screen G4 on the display 201 (step SB7). Then, when the decompression ends, the control unit 100 displays the main screen HG on the display 201 (step SB8).

[0219] Returning to the description of step SB4, when it is determined that the cancel key Ky2 is long-pressed (step SB4: Yes), the control unit 100 determines whether the long-press operation of the cancel key Ky2 is the fourth long-press operation of the cancel key Ky2 in one cooking (step SB9).

[0220] When it is determined that the long-press operation of the cancel key Ky2 is the fourth long-press operation (step SB9: Yes), the control unit 100 transfers the process to step SB16 and executes the processes after step SB16.

[0221] On the other hand, when it is determined that the long-press operation of the cancel key Ky2 is not the fourth long-press operation (step SB9: No), the control unit 100 stops the power supply to the load 115 and temporarily stops the cooking of the cooking unit 102 (step SB10).

[0222] Next, the control unit 100 starts displaying the pressure-cooking cancellation confirmation screen G5 on the display 201 (step SB11).

[0223] Next, the control unit 100 starts counting down the remaining time for cooking cancellation (step SB12). When a predetermined period, for example 15 seconds, is set, in step SB12, the countdown starts from 15 seconds.

[0224] The control unit 100 determines whether the start key Ky6 has been operated (step SB13).

[0225] When it is determined that the start key Ky6 has not been operated (step SB13: NO), the control unit 100 determines whether the cancel key Ky2 has been operated (step SB14).

[0226] When it is determined that the cancel key Ky2 has not been operated (step SB14: NO), the control unit 100 determines whether the countdown has reached zero seconds for the remaining cooking cancellation time (step SB15).

[0227] When it is determined that the countdown has not reached zero seconds for the remaining cooking cancellation time (step SB15: NO), the control unit 100 returns the process to step SB13 and makes the determination of step SB13 again.

[0228] On the other hand, when it is determined that the countdown has reached zero seconds for the remaining cooking cancellation time (step SB15: YES), the control unit 100 ends the pressure cooking of the cooking unit 102 and starts decompression (step SB16).

[0229] Next, the control unit 100 displays the second decompression in - progress screen G6 on the display 201 (step SB17). Then, when the decompression is completed, the control unit 100 displays the main screen HG on the display 201 (step SB18).

[0230] Returning to the description of step SB13, when it is determined that the start key Ky6 has been operated (step SB13: YES), the control unit 100 resumes displaying the pressure - cooking in - progress screen G3 on the display 201 (step SB19) and resumes the temporarily - stopped cooking (step SB20).

[0231] Returning to the description of step SB14, when it is determined that the cancel key Ky2 has been operated (step SB14: YES), the control unit 100 executes the processes after step SB16.

[0232] [1 - 3. Effects, etc.]

[0233] The heating cooker 1 includes a cooking unit 102 that cooks by means of a load 115 related to cooking, and a control unit 100. When the cancel key Ky2 of the operation keys Ky of the heating cooker 1 is operated during the cooking of the cooking unit 102, the control unit 100 stops the power supply to the load 115, temporarily stops the cooking of the cooking unit 102, and when a specified time has elapsed during the temporarily stopped cooking, the cooking of the cooking unit 102 is aborted.

[0234] Thereby, even if the cancel key Ky2 is operated, the cooking is not immediately aborted. Therefore, a period during which the user can confirm whether the cancel key Ky2 has been inadvertently operated can be provided to the user, and inadvertent cooking abortion by the user can be suppressed. Also, during the temporary stop of cooking, the power supply to the load 115 related to cooking is stopped, so the safety of the user during the temporary stop of cooking can be ensured. Therefore, inadvertent cooking abortion by the user can be suppressed while ensuring the safety of the user.

[0235] When the cancel key Ky2 is operated during the period of temporarily stopping the cooking of the cooking unit 102, even before the specified time has elapsed, the control unit 100 aborts the cooking of the cooking unit 102.

[0236] Thereby, in the case of intentionally operating the cancel key Ky2, by operating the cancel key Ky2 again, the cooking can be aborted without waiting for the specified time to elapse. Therefore, a heating cooker 1 that is convenient for the user can be provided.

[0237] When the start key Ky6 is operated during the period of temporarily stopping the cooking of the cooking unit 102, the control unit 100 resumes the cooking of the temporarily stopped cooking unit 102.

[0238] Thereby, in the case of inadvertently operating the cancel key Ky2, the cooking can be resumed by operating the start key Ky6. Therefore, even in the case of an inadvertent temporary stop of cooking, the cooking can be easily resumed.

[0239] During one cooking of the cooking unit 102, the cooking can be temporarily stopped three times based on the operation of the cancel key Ky2. If the cancel key Ky2 is operated more than three times during one cooking of the cooking unit 102, the control unit 100 aborts the cooking of the cooking unit 102 without temporarily stopping the cooking of the cooking unit 102.

[0240] Since power is not supplied to the load 115 during the temporary stop, if the cooking can be temporarily stopped indefinitely, it may not be possible to maintain the quality of the dish after cooking. Therefore, by setting a limit on the number of times the cooking can be temporarily stopped, inadvertent cooking abortion by the user can be suppressed, and a decrease in the quality of the dish after cooking can be suppressed.

[0241] When the control unit 100 aborts the pressure cooking of the cooking unit 102, it reduces the pressure in the cooking space S.

[0242] Accordingly, when aborting the pressure cooking, the pressure in the cooking space S is reduced. Therefore, it is possible to abort the pressure cooking while ensuring the safety of the user.

[0243] The control unit 100 measures the remaining cooking time during the cooking of the cooking unit 102, and stops measuring the remaining cooking time during the period when the cooking of the cooking unit 102 is temporarily stopped.

[0244] Accordingly, the measurement of the remaining cooking time stops along with the temporary stop of the cooking. Therefore, it is possible to execute the temporary stop of the cooking in such a way that the time of the temporary stop of the cooking is not reflected in the cooking end time. And when restarting the cooking, it is possible to start measuring the time again from the correct remaining cooking time that was not counted down during the temporarily stopped time and restart the cooking.

[0245] The heating cooker 1 includes a display 201. During the period when the cooking of the cooking unit 102 is temporarily stopped, the control unit 100 alternately switches the display of the first screen G10 and the second screen G20 through the display 201. The first screen G10 guides that the cooking can be aborted by operating the cancel key Ky2, and the second screen G20 guides that the cooking can be restarted by operating the start key Ky6.

[0246] Accordingly, the user can easily grasp which operation key Ky can be used to abort the cooking and which operation key Ky can be used to restart the cooking. Therefore, it is possible to improve the convenience of the user when aborting the cooking or restarting the cooking. And even when the two screens cannot be simultaneously displayed in the display area of the display 201, the user can easily grasp which operation key Ky can be used to abort the cooking and which operation key Ky can be used to restart the cooking.

[0247] The load 115 includes at least one of a motor 113 that drives a stirring member for stirring the food to be cooked and a heater 112 that heats the food to be cooked.

[0248] Accordingly, during the temporary stop of the cooking, even if the lid 11 is opened, the stirring member is not driven. Therefore, it is possible to prevent the food to be cooked, which is heated by the driving of the stirring member, from splashing onto the user. And during the temporary stop of the cooking, the heater does not heat the food to be cooked. Therefore, it is possible to suppress the blowing out of the heated moisture from the heating cooker 1. Thus, the safety of the user can be ensured.

[0249] The heating cooker 1 is provided with an operation key Ky.

[0250] Accordingly, even when the user accidentally touches the heating cooker 1 and erroneously operates the cancel key Ky2, it is possible to suppress an accidental interruption of cooking while ensuring the safety of the user.

[0251] The operation key Ky is a key constituted by a capacitive touch sensor.

[0252] When the operation key Ky is a key constituted by a capacitive touch sensor, there is a high possibility of erroneously operating the cancel key Ky2 even if the user accidentally touches the heating cooker 1, for example, touches the cancel key Ky2 when touching the cancel key Ky2 or wiping the heating cooker 1 with a wet cloth. However, even when there is a high possibility of erroneously operating the cancel key Ky2, the heating cooker 1 can suppress an accidental interruption of cooking while ensuring the safety of the user.

[0253] Regarding a control method of the heating cooker 1 having a load 115 related to cooking, when the cancel key Ky2, which is an operation key Ky of the heating cooker 1, is operated during cooking, the power supply to the load 115 is stopped to temporarily stop cooking, and when a predetermined time has elapsed during the temporary stop of cooking, the cooking is aborted.

[0254] Accordingly, the same effect as that of the above-described heating cooker 1 is achieved.

[0255] The control program 121 causes the control unit 100 of the heating cooker 1 to perform the following control: during cooking, when the cancel key Ky2, which is an operation key Ky of the heating cooker 1, is operated, the power supply to the load 115 is stopped to temporarily stop the cooking of the load 115, and when a predetermined time has elapsed during the temporary stop of cooking, the cooking is aborted.

[0256] Accordingly, the same effect as that of the above-described heating cooker 1 is achieved.

[0275] (Supplementary Note)

[0276] Through the description of the above embodiment, the following technology is disclosed.

[0277] (Technology 1) A heating cooker, comprising: a cooking unit that cooks by means of a load related to cooking; and a control unit that, during the cooking of the cooking unit, when a first key serving as an operation key of the heating cooker is operated, the control unit stops the power supply to the load and temporarily stops the cooking of the cooking unit, and when a specified time has elapsed after the temporary stop of cooking, the control unit aborts the cooking of the cooking unit.

[0278] Thus, even if the first key is operated, the cooking is not immediately aborted. Therefore, a period can be given to the user to confirm whether the first key has been inadvertently operated, and the inadvertent abortion of cooking by the user can be suppressed. Also, during the temporary stop of cooking, the power supply to the load related to cooking is stopped, so the safety of the user during the temporary stop of cooking can be ensured. Thus, the inadvertent abortion of cooking by the user can be suppressed while ensuring the safety of the user.

[0279] (Technology 2) The heating cooker according to Technology 1, wherein, during the period of temporarily stopping the cooking of the cooking unit, when the first key or a second key serving as an operation key different from the first key is operated, even before the specified time has elapsed, the control unit aborts the cooking of the cooking unit.

[0280] Thus, in the case of intentionally operating the first key, by operating the first key again, the cooking can be aborted without waiting for the elapse of the specified time. Therefore, a heating cooker that is convenient for the user to use can be provided.

[0281] (Technology 3) The heating cooker according to Technology 2, wherein, during the period of temporarily stopping the cooking of the cooking unit, when a third key serving as an operation key different from the first key and the second key is operated, the control unit resumes the cooking of the temporarily stopped cooking unit.

[0282] Thus, in the case of inadvertently operating the first key, the cooking can be resumed by operating the third key. Therefore, even in the case of an inadvertent temporary stop of cooking, the cooking can be easily resumed.

[0283] (Technology 4) The heating cooker according to any one of Technologies 1 to 3, wherein, in one cooking performed by the cooking unit, the control unit can execute the temporary stop of cooking based on the operation of the first key a specified number of times, and in one cooking performed by the cooking unit, when the first key is operated more than the specified number of times, the control unit does not temporarily stop the cooking of the cooking unit but aborts the cooking of the cooking unit.

[0284] Since power is not supplied to the load during the temporary stop, if the cooking can be temporarily stopped indefinitely, it may not be possible to maintain the quality of the dish after cooking is completed. Therefore, by setting a limit on the number of times of temporary stop, it is possible to suppress the interruption of cooking by the user inadvertently and to suppress the deterioration of the quality of the dish after cooking is completed.

[0285] (Technology 5) The heating cooker according to any one of Technologies 1 to 4, wherein when the control unit aborts the pressure cooking of the cooking unit, the cooking space for cooking the food to be cooked is depressurized.

[0286] Thus, since the cooking space is depressurized when the pressure cooking is aborted, it is possible to abort the pressure cooking while ensuring the safety of the user.

[0287] (Technology 6) The heating cooker according to any one of Technologies 1 to 6, wherein during the cooking of the cooking unit, the control unit measures the remaining time until the end of cooking, that is, the remaining cooking time, and during the period when the cooking of the cooking unit is temporarily stopped, the control unit stops measuring the remaining cooking time.

[0288] Thus, the remaining cooking time is stopped along with the temporary stop of cooking, so that the temporary stop of cooking can be executed in such a way that the time of the temporary stop of cooking is not reflected in the cooking end time. And when cooking is restarted, it is possible to start counting from the correct remaining cooking time at which the time of the temporary stop has not been counted down and restart cooking.

[0289] (Technology 7) The heating cooker according to any one of Technologies 1 to 6, wherein the heating cooker includes a display, and during the period when the cooking of the cooking unit is temporarily stopped, the control unit alternately switches and displays a first screen and a second screen on the display, the first screen guiding that cooking can be aborted by operating the first key, and the second screen guiding that cooking can be restarted by operating a third key which is an operation key different from the first key.

[0290] Thus, the user can easily grasp which operation key to operate to abort cooking and which operation key to operate to restart cooking, so that the convenience of the user when aborting cooking or restarting cooking can be improved. And even when the two screens cannot be simultaneously displayed in the display area of the display, the user can easily grasp which operation key to operate to abort cooking and which operation key to operate to restart cooking.

[0291] (Technology 8) The heating cooker according to any one of Technologies 1 to 7, wherein the heating cooker includes one or more LEDs, and during a temporary stop of cooking by the cooking unit, the control unit counts down the specified time and notifies the specified time obtained by the countdown through the LEDs.

[0292] Thereby, it is possible to report to the user how much of the specified time remains via the LEDs.

[0293] (Technology 9) The heating cooker according to any one of Technologies 1 to 8, wherein the heating cooker includes a sound output unit, and during a temporary stop of cooking by the cooking unit, the control unit counts down the specified time and reports the specified time obtained by the countdown through the sound output unit.

[0294] Thereby, it is possible to report to the user how much of the specified time remains via the output of sound.

[0295] (Technology 10) The heating cooker according to any one of Technologies 1 to 9, wherein the load includes at least one of a motor that drives a stirring member for stirring the food to be cooked and a heater that heats the food to be cooked.

[0296] Thereby, during a temporary stop of cooking, the stirring member is not driven, and thus, it is possible to prevent the food to be cooked, which is heated by the driving of the stirring member, from splashing onto the user. Also, during a temporary stop of cooking, the heater does not heat the food to be cooked, and thus, it is possible to suppress the blown-out heated moisture from the heating cooker. Therefore, the safety of the user can be ensured.

[0297] (Technology 11) The heating cooker according to any one of Technologies 1 to 10, wherein the heating cooker includes the operation key.

[0298] Thereby, when the heating cooker is accidentally touched without intending to operate it, even if the first key is operated, it is possible to suppress the accidental interruption of cooking by the user while ensuring the safety of the user.

[0299] (Technology 12) The heating cooker according to Technology 11, wherein the operation key is a key constituted by a capacitive touch sensor.

[0300] When the operation key is a key constituted by a capacitive touch sensor, although there are accidental operations of the heating cooker such as touching the first key or touching the first key when wiping the heating cooker with a wet cloth, the possibility of erroneously operating the first key is high. However, the heating cooker can suppress the accidental interruption of cooking by the user while ensuring the safety of the user even when the possibility of erroneously operating the first key is high.

[0301] (Technology 13) A control method for a heating cooker, wherein the heating cooker cooks by means of a load related to cooking. When a first key, which is an operation key of the heating cooker during cooking, is operated, the power supply to the load is stopped to temporarily stop cooking, and when a specified time has elapsed during the temporary stop of cooking, the cooking is aborted.

[0302] Thereby, the same effect as that of the heating cooker of Technology 1 is achieved.

[0303] (Technology 14) A recording medium that records a program which causes a control unit of a heating cooker that cooks by means of a load related to cooking to perform the following control: when a first key, which is an operation key of the heating cooker during cooking, is operated, the power supply to the load is stopped to temporarily stop cooking, and when a specified time has elapsed during the temporary stop of cooking, the cooking is aborted.

[0304] Thereby, the same effect as that of the heating cooker of Technology 1 is achieved.

[0305] Industrial applicability

[0306] As described above, the heating cooker, the control method for the heating cooker, and the recording medium of the present invention can be used for applications such as a rice cooker, an automatic cooking pot, etc., which are heating cookers capable of aborting cooking by operating an operation key of the heating cooker.
