Description

  The present invention relates to a cooking device.

  2. Description of the Related Art Conventionally, there is known a cooking device that can perform cooking in a grill using a cooking container such as a Dutch oven. When performing cooking by heating, a cooking container containing an object to be cooked is stored in a grill, and the upper and lower burners are ignited and burned. Then, the cooking in the cooking container proceeds by being heated from above and below by the upper fire burner and the lower fire burner. However, when the upper fire burner and the lower fire burner continue to burn, the upper temperature in the heating chamber rises higher than the lower temperature. As a result, the temperature becomes uneven at the upper and lower parts of the cooking container, and when the food to be cooked accommodated in the cooking container is a baked product such as bread or cake, the baked product cannot be baked well. There was a point.

  Therefore, an initial heating time shorter than the cooking time is calculated based on the cooking time set manually, and after the initial heating time has elapsed after the ignition means is activated and the upper and lower burners burn, There has been proposed a gas cooker that extinguishes only the fire burner and then burns only the lower fire burner with low heating power until the timer counts the input cooking time (for example, see Patent Document 1).

  With reference to FIG. 3 and FIG. 4, cooking using a Dutch oven will be described. In this embodiment, DO cooking using a Dutch oven (hereinafter simply referred to as DO) is possible. DO is a pan with a metal lid, and is generally made of cast iron. For example, an aluminum alloy, steel plate, or stainless steel can also be used. DO cooking has the advantage that the pan is thick, so there is little temperature change and the entire pan is kept at a uniform temperature, and the cooked item is thoroughly ignited. Moreover, the water vapor | steam from the to-be-cooked object fills the clearance gap between a lid and a pan, and also becomes a sealed state with the weight of a lid. If it continues to be heated in this state, the internal atmospheric pressure rises and it can be in the same state as the pressure cooker. And since water | moisture content does not escape as a vapor | steam, there also exists an advantage that the anhydrous cooking using the water | moisture content of a to-be-cooked object is easy.

  In the stove 1 of the present embodiment, a deep pan 101 (see FIG. 3) and a shallow pan 102 (see FIG. 4) as examples of DO can be used. The deep pan 101 has a deep bottom, and is a pan having a capacity of 800 ml as an example. The shallow pan 102 is shallower than the deep pan 101.

  In the upper fire burner 26, the amount of gas flowing through the upper fire burner 26 can be adjusted in two steps by opening and closing the heating power switching valve 94. When the thermal power switching valve 94 is closed, the upper fire burner 26 burns with low thermal power, and when the thermal power switching valve 94 is opened, the upper fire burner 26 burns with high thermal power. As a result, the heating power of the upper fire burner 26 can be controlled in two stages, a weak heating power and a strong heating power. As described above, in the stove 1, the thermal powers of the lower fire burner 25 and the upper fire burner 26 can be adjusted independently in two stages of strong fire power and weak fire power.

  Further, as shown in FIG. 5, the lower fire burner 25A is provided with an igniter 51 and a thermocouple 45, and the lower fire burner 25B is provided with an igniter 52 and a thermocouple 46, respectively.

When the power switch 10 is turned on by the user, the power of the dry battery is supplied to the power circuit 81 via the switch input circuit 82, and the transistor switch of the power circuit 81 is turned on. Thereby, current flows from the power supply circuit 81 to various circuits, and the power supply of the stove 1 is turned on. In the stove 1, the power source of the main body is automatically turned off when there is no operation for 3 minutes or more after the power switch 10 is turned on. Thereby, consumption of battery power can be prevented.

  The operation panel circuit 83 detects various operations of the stove operation panel 18 and the grill operation panel 19 and inputs them to the control circuit 70. The ignition button operation circuit 84 detects pressing and rotation operations of the ignition buttons 11 to 14 and inputs them to the control circuit 70.

The DO cooking table 741 has an initial heating time T1, a double-fire high-heat power heating time T2, a double-fire low-heat power heating time T3, and a single-fire low-heat power heating time T4 with respect to a plurality of patterns of the DO cooking set time P, respectively. Store it in association. The set time P corresponds to the “heating time” of the present invention.

  The set time P is a heating time when cooking the food to be cooked using the deep pan 101 or the shallow pan 102, and is a time that can be set manually by the user using the grill operation panel 19. In the grill operation panel 19, the set time P can be set in units of “minutes” in consideration of ease of setting by the user.

  The initial heating time T1 is a time required for the initial heating in which the lower-burner burner 25 and the upper-burner burner 26 are first burned with high heat and the deep pot 101 or the shallow pot 102 itself is heated. Regardless of the time, the same fixed time is assumed. The method for determining the initial heating time T1 will be described later. In this embodiment, it is set to 180 seconds. The both-fire high-heat power heating time T2 is a time during which the lower fire burner 25 and the upper fire burner 26 are both burned with strong heat after the initial heating, and differs depending on the set time P. The both-fire low-heating power heating time T3 is a time for both the lower-burner burner 25 and the upper-burner burner 26 to be switched to the lower heating power after both the two-fire high heating power heating, and varies depending on the set time P. The one-flame low heating power heating time T4 is a time for extinguishing the upper fire burner 26 and burning only the lower fire burner 25 with a low heating power after the two fire weak heating power heating, and differs depending on the set time P. In the following description, the initial heating time T1, the two-fire high heating power heating time T2, the both-fire low heating power heating time T3, and the one-fire low heating power heating time T4 are referred to as times T1, T2, T3, and T4, respectively.

The first data area 741A is a data area for the set time P = 1 to 10 minutes, and the second data area 741B is a data area for the set time P = 11 to 30 minutes. The first data area 741A and the second data area 741B have different allocation methods for the times T1 to T4.

  First, a method for distributing the times T1 to T4 in the first data area 741A will be described. In the first data area 741A, in principle, the remaining time obtained by subtracting the time T1 (180 seconds in the present embodiment) from ½ hour of the set time P is defined as time T2, and ½ hour of the other set time P. To time T3. For example, when the set time P is 10 minutes, the half time of the set time P is 300 seconds, so the remaining 120 seconds obtained by subtracting 180 seconds, which is the time T1, from 300 seconds is the time T2, and the time T3 is It becomes 300 seconds as it is.

  However, when ½ time of the set time P does not reach the time T1, the following processing is performed. When the set time P is 5 minutes, the half time of the set time P is 150 seconds, and therefore does not reach the time T1, which is 180 seconds. In this case, the time T2 is set to 0 seconds, and the remaining time of -30 seconds obtained by subtracting 180 seconds, which is the time T1, from 150 seconds is added to the other 150 seconds, which is 1/2 of the set time P. As a result, the obtained 120 seconds is defined as time T3.

  In the present embodiment, in consideration of the convenience of the user, the set time P can be set to 3 minutes or less in the first data area 741A. In this case, the time T1 is set to the same time as the set time P, but when the time T1 elapses after ignition, the timer is increased as it is, so that the time T2 to T4 is necessarily set to 0.

Next, a method for distributing the times T1 to T4 in the second data area 741B will be described. In the second data area 741B, in principle, the remaining time obtained by subtracting the time T1 from the set time P is divided into three equal parts and assigned to the times T2 to T4, respectively. When the remaining time cannot be divided into three equal parts, the remaining time is distributed according to the following method.
When the set time P = 21 minutes, it is assigned to 3 + 6 + 6 + 6, and time T1 = 3 minutes, time T2 = 6 minutes, time T3 = 6 minutes, and time T4 = 6 minutes.
When the set time P = 22 minutes, it is assigned to 3 + 6 + 6 + 7, and the time T1 = 3 minutes, the time T2 = 6 minutes, the time T3 = 6 minutes, and the time T4 = 7 minutes.
When the set time P = 23 minutes, it is assigned to 3 + 6 + 7 + 7, and time T1 = 3 minutes, time T2 = 6 minutes, time T3 = 7 minutes, and time T4 = 7 minutes.
When the set time P = 24 minutes, it is assigned to 3 + 7 + 7 + 7, and the time T1 = 3 minutes, the time T2 = 7 minutes, the time T3 = 7 minutes, and the time T4 = 7 minutes.

  In the above example, the remaining time is divided into three equal parts, and the time that cannot be divided is distributed in the order of time T4 and time T3. The method of distributing the time that cannot be divided is not limited to the above example, but by distributing as in the above example, the thermal power is shifted to the low thermal power side, so that the gas consumption in the stove 1 can be saved.

  And in this embodiment, the set time P which the stove 1 recommends is predetermined according to the kind of pan used for DO cooking. The deep pan 101 is used for, for example, a thing with much moisture such as a stew, a bread, a cake, or the like, so that it is estimated that the heating time is relatively long. On the other hand, the shallow pan 102 is used for grilling vegetables, cooking pizza, fried foods, finishing of grilled foods, etc., so it is estimated that the heating time is relatively short. Therefore, when using the shallow pan 102, setting within the range of the set time P = 1 to 10 minutes is recommended, and when cooking using the deep pan 101, the set time P is within the range of 11 to 30 minutes. Setting in is recommended. These recommended times can be notified to the user, for example, in the manual or instruction manual of the stove 1. Therefore, the user decides and sets the set time P within the range of the recommended set time P according to the type of pot used for DO cooking. Cooking can be done.

  Next, a method for determining the time T1 will be described. DO cooking is an indirect dish in which an object to be cooked is cooked using the deep pan 101 or the shallow pan 102. When performing indirect cooking, since the heat capacity of the pan is large, the influence of the amount of heat required to heat the pan itself in addition to the amount of heat required to heat the cooking object cannot be ignored. When the amount of heat for heating the pan itself is not sufficient, heat is not sufficiently transmitted to the cooking object in the pan, and the cooking object is likely to be burnt. Therefore, it is necessary to sufficiently consider the time required for heating the pan itself as the time T1. Therefore, the time T1 is determined by performing the following experiment in the present embodiment.

  First, the experimental method will be described. Using a pan 101 having a capacity of 800 ml, a plurality of pans with different amounts of water were prepared, and for each of these pans, the lower fire burner 25 and the upper fire burner 26 were both burned with strong heat in the grill cabinet 20. The rise in water temperature when heated in a state was measured with a temperature sensor (thermocouple), and the time to reach 100 ° C. was measured. The measurement position is the center of the space in the pan. And the temperature data of five typical pots were extracted from the temperature data measured with each pot, and were put together in the graph shown in FIG.

  The experimental results will be described. As shown in FIG. 8, the boiling time of each pan is about 13 minutes for 800 ml of water, about 8 minutes for 400 ml of water, about 5.5 minutes for 200 ml of water, and about 5 minutes for 100 ml of water. In the case of 4.3 minutes and 50 ml of water, it was about 3.6 minutes. From these results, as the amount of water in the pot decreases by half, the interval of boiling required time is also shortened by about half, so it can be estimated that the time required to reach 100 ° C in the pot without water is about 3 minutes. . And these 3 minutes can be considered as the heat capacity inherent to the pan as it is. Accordingly, the time T1 is determined to be 3 minutes (180 seconds) when the set time P recommended when using the deep pan 101 is in the range of 11 to 30 minutes.

  Further, as described above, cooking with a relatively short heating time is assumed for the shallow pan 102, and therefore, in this embodiment, the set time P is set to a maximum of 10 minutes. Therefore, even if the capacity of the shallow pan 102 is small and heat is easily transmitted, it is considered that the cooking object is not easily burned due to residual heat. Therefore, even when the set time P is in the range of 1 to 10 minutes, the time T1. The same 3 minutes as the deep pot 101. In addition, about time T1 of the shallow pot 102, you may determine time T1 intrinsic | native to the shallow pot 102 by performing said experiment similarly to the deep pot 101. FIG.

  The DO cooking process executed by the CPU 71 will be described with reference to the flowcharts of FIGS. 9 and 10. When the user turns on the power switch 10, the CPU 71 periodically reads out the “DO cooking program” from the ROM 72 and executes this processing.

  First, the CPU 71 determines whether or not the set time P has been set (S1). The user inputs the set time P using the grill operation panel 19 and finally presses a DO cooking start button (not shown). The CPU 71 stores the input set time P in the RAM 73 and completes the setting of the set time P. If the set time P is not set (S1: NO), this process is terminated.

  When a user intends to cook DO using the shallow pan 102, the set time P suitable for the cooking object to be cooked from the set time P = 1 to 10 minutes recommended for the shallow pan 102. Enter to set. If you are going to cook DO using the pan 101, enter the set time P that is appropriate for the food to be cooked from the set time P = 11 to 30 minutes recommended for the pan 101. Set.

  When the set time P is set (S1: YES), the CPU 71 refers to the DO cooking table 741 (see FIG. 7) stored in the flash memory 74, and time T1, time T2 corresponding to the set time P. , Time T3 and time T4 are read (S2). Various read data are written in the RAM 73.

  For example, in the case of DO cooking using the shallow pan 102, when the set time P = 5 minutes is set, the time T1 = 180 seconds, the time T2 = 0 seconds, the time T3 = 120 seconds, and the time T4 = 0 seconds are read. , Written in the RAM 73. When the set time P = 10 minutes is set, the time T1 = 180 seconds, the time T2 = 120 seconds, the time T3 = 300 seconds, and the time T4 = 0 seconds are read and written to the RAM 73, respectively. In addition, when the set time P = 20 minutes is set for DO cooking using the deep pan 101, time T1 = 180 seconds, time T2 = 300 seconds, time T3 = 360 seconds, and time T4 = 360 seconds are read. Then, the data is written in the RAM 73.

  Next, it is determined whether or not an ignition operation has been performed (S3). The user installs the shallow pan 102 or the deep pan 101 containing the food to be cooked in the grill cabinet 20, closes the grill door 8, and then presses the ignition button 14 to perform the ignition operation. Until there is an ignition operation (S3: NO), the process returns to S3 and enters a standby state.

  When the ignition operation is performed (S3: YES), as shown in FIG. 5, the igniters 51 to 51 are opened after the original solenoid valve 91, the safety valve 92, the thermal power switching valves 93 and 94, and the upper fire cutoff valve 95 are opened. The lower fire burner 25 and the upper fire burner 26 are ignited by driving 53 (S4). After ignition, both the lower fire burner 25 and the upper fire burner 26 are in a combustion state with both fires and strong heat that burns with strong heat, and DO cooking starts. In addition, this process is complete | finished when the misfire of the lower fire burner 25 and the upper fire burner 26 is detected by the thermocouples 45-47.

  Next, the CPU 71 starts another program and starts counting the cooking time t using the output from the timer 75 (see FIG. 3) (S5). The count value is stored in the RAM 73. The count value is reset when the program is started.

  Next, it is determined whether or not the set time P is 3 minutes or longer (S7). When the set time P is less than 3 minutes (S7: NO), it is determined whether or not the cooking time t has reached the time T1 in the combustion state of both fires and strong heating power (S11). For example, when the set time P is 2 minutes, since the time T1 is 120 seconds (see FIG. 7), it is determined whether or not the cooking time t has reached 120 seconds. Until the cooking time t reaches the time T1 (S11: NO), the process returns to S11 and the combustion state of the two fires is continued. Then, when the cooking time t reaches time T1 (S11: YES), the lower solenoid burner 25 and the upper flame burner 26 are extinguished together as shown in FIG. 10 by closing the original solenoid valve 91 and the safety valve 92. (S19), this process is terminated.

  On the other hand, returning to FIG. 9, when the set time P is 3 minutes or more (S7: YES), it is determined whether the cooking time t has reached the time T1 (S8). Until the cooking time t reaches time T1 (S8: NO), the combustion state of both fires is continued, and the process returns to S8 and enters a standby state. During this time, the deep pan 101 or the shallow pan 102 is heated, and the temperature of the whole pan rises. When the cooking time t reaches time T1 (S8: YES), it is determined whether or not the time T2 is 0 with reference to the time T2 stored in the RAM 73 (S9). For example, when the set time P is 5 minutes, the time T2 is 0, and when the set time P is 20 minutes, the time T2 is 300 seconds.

  When the time T2 is 0 (S9: YES), the process proceeds to S12 shown in FIG. When the time T2 is not 0 (S9: NO), it is determined whether the cooking time t has reached the sum of the time T1 and the time T2 (S10). For example, when the set time P is 20 minutes, referring to the times T1 and T2 stored in the RAM 73, since the time T1 is 180 seconds and the time T2 is 300 seconds, has the cooking time t reached 180 + 300 = 480 seconds? Judge whether or not. Until the cooking time t reaches the sum of the time T1 and the time T2 (S10: NO), the process returns to S10, and the combustion state of both fires is continued.

  When the cooking time t reaches the total of time T1 + time T2 (S10: YES), as shown in FIG. 10, the time T3 stored in the RAM 73 is referenced to determine whether the time T3 is 0 (S12). ). When the time T3 is 0 (S12: YES), the original solenoid valve 91 and the safety valve 92 are closed, the lower fire burner 25 and the upper fire burner 26 are extinguished together (S19), and this process is terminated.

  On the other hand, when the time T3 is not 0 (S12: NO), the lower power burner 25 and the upper fire burner 26 are switched from the strong heat power to the low heat power by closing the heat power switching valves 93 and 94 shown in FIG. It is set as the combustion state of a low heat power (S13). And it is judged whether the cooking time t reached the sum total of time T1 + time T2 + time T3 in the combustion state of both fire weak thermal powers (S14). For example, when the set time P is 20 minutes, referring to the times T1, T2, and T3 stored in the RAM 73, the time T1 is 180 seconds, the time T2 is 300 seconds, and the time T3 is 360 seconds. It is determined whether or not 180 + 300 + 360 = 840 seconds. Until the cooking time t reaches the sum of time T1 + time T2 + time T3 (S14: NO), the process returns to S14 to continue the combustion state of both fires and low heat.

  When the cooking time t reaches the sum of time T1 + time T2 + time T3 (S14: YES), the time T4 stored in the RAM 73 is referenced to determine whether the time T4 is 0 (S15). In the present embodiment, as shown in FIG. 7, when the set time P is within the range of 1 to 10 minutes (first data area 741A), all the times T4 are set to 0. When the time T4 is 0 (S15: YES), the original solenoid valve 91 and the safety valve 92 are closed, the lower fire burner 25 and the upper fire burner 26 are extinguished together (S19), and this process is terminated.

  On the other hand, when the time T4 is not 0 (S15: NO), the upper fire burner 26 is extinguished by closing the upper fire cutoff valve 95 shown in FIG. 5 (S16), and only the lower fire burner 25 is weakly heated. Set the combustion state to a one-fire low heat power to burn. In the present embodiment, only the set time P is within the range of 11 to 30 minutes (second data area 741B), and the time T4 is set to 180 to 540 seconds. Therefore, in the DO cooking using the deep pan 101, in principle, it is possible to set the combustion state to one-sided low heat power in the second half of cooking. Thus, when the whole inside of the grill cabinet 20 is heated to a temperature suitable for cooking, the upper fire burner 26 is extinguished and the lower fire burner 25 is maintained with a low heating power, so that the lower portion of the deep pan 101 is overheated. Can be suppressed. Therefore, since the baking unevenness of the upper and lower parts of the cooking object in the deep pan 101 is reduced, a high-quality cake or bread can be baked. Furthermore, since the upper fire burner 26 is extinguished and heated only by the lower fire burner 25 when the entire inside of the grill cabinet 20 is heated to a temperature suitable for cooking, the gas consumption of the stove 1 can be saved.

  Next, it is determined whether or not the cooking time t has reached the sum of time T1 + time T2 + time T3 + time T4 in the combustion state of one-sided low heat power (S17). For example, when the set time P is 20 minutes, referring to the times T1, T2, T3, and T4 stored in the RAM 73, the time T1 is 180 seconds, the time T2 is 300 seconds, the time T3 is 360 seconds, and the time T4 is 360 seconds. Therefore, it is determined whether the cooking time t has reached 180 + 300 + 360 + 360 = 1200 seconds. Until the cooking time t reaches the sum of time T1 + time T2 + time T3 + time T4 (S17: NO), the process returns to S17 to continue the combustion state of one-sided low heat power.

  When the cooking time t reaches the sum of time T1 + time T2 + time T3 + time T4 (S17: YES), the lower solenoid burner 25 that has been burned with low heat until now is closed by closing the original solenoid valve 91 and the safety valve 92. Is extinguished (S19), and this process is terminated.

  As described above, DO cooking using the grill cabinet 20 is possible with the stove 1 of the present embodiment. DO cooking is cooking which heats the to-be-cooked material in a pan by heating the pan (for example, the deep pan 101 or the shallow pan 102) which put the to-be-cooked object in the grill cabinet 20. FIG. In DO cooking, in addition to the amount of heat required for heating the cooking object, the amount of heat required to heat the pan itself is affected. Therefore, in the present embodiment, after ignition and combustion start, initial heating is performed in which the upper fire burner 26 and the lower fire burner 25 are burned for a time T1 required for heating the pan itself. Thereby, even if the heat capacity of the pan is large, the pan itself can be heated sufficiently. Then, after the initial heating, each combustion operation of the upper fire burner 26 and the lower fire burner 25 is controlled in a combustion mode corresponding to the set time P set on the grill operation panel 19. Thereby, it can fully heat, without the to-be-cooked thing in a pan becoming raw-burning.

  In the present embodiment, the DO cooking table 741 is stored in the flash memory 74. The DO cooking table 741 is table information in which the heating power and the combustion time of each of the upper fire burner 26 and the lower fire burner 25 are associated with each other according to a plurality of patterns of the set time P set on the grill operation panel 19. is there. Based on the DO cooking table 741, the CPU 71 of the stove 1 determines the respective heating power and combustion time of the upper fire burner 26 and the lower fire burner 25 corresponding to the set time P set on the grill operation panel 19. Each combustion operation of the burner 26 and the lower fire burner 25 is controlled. Thereby, heat cooking can be performed with the heating power and combustion time appropriate for the set time P. In addition, regarding the DO cooking table 741, specific cooking power and combustion time are associated with each other in accordance with a plurality of patterns of the set time P, so that cooking suitable for actual cooking can be appropriately performed.

  Further, in the present embodiment, the DO cooking table 741 stores an initial heating time T1, a double-fire high-heat power heating time T2, and a double-fire low-heat power heating time T3 respectively associated with a plurality of patterns of the set time P. Both-fire high-heat power heating time T2 is a time for burning both the upper fire burner 26 and the lower fire burner 25 with strong heat. Both fires low heating power heating time T3 is a time for burning both the upper fire burner 26 and the lower fire burner 25 with low heat power. Accordingly, the CPU 71 determines the times T1 to T3 based on the DO cooking table 741, so that the upper fire burner 26 and the lower fire burner 25 are set in the combustion mode suitable for the set time P set on the operation panel 19 for grill. Can be burned. In addition, after the initial heating, both the upper fire burner 26 and the lower fire burner 25 are burned with a strong heating power, so that the cooking object can be efficiently heated in a short time. By using a low heating power for both, the food in the pan can be prevented from being burned by overheating.

  Moreover, in this embodiment, DO cooking table 741 memorize | stores the one-flame low heat power heating time T4 in addition to time T1-T3. Time T4 is a time for extinguishing the upper fire burner 26 and burning only the lower fire burner 25 with low heat power. The CPU 71 determines times T1 to T4 corresponding to the set time P set on the grill operation panel 19 based on the DO cooking table 741. By burning the upper fire burner 26 and the lower fire burner 25 with both fires at time T <b> 1 to T <b> 3, hot air moves to the upper side in the grill cabinet 20. Then, after burning the upper fire burner 26 and the lower fire burner 25, at time T4, the upper fire burner 26 is extinguished and only the lower fire burner 25 is burned, so that the temperature in the grill box 20 is made uniform. The Therefore, the stove 1 can heat the cooking object in the pan satisfactorily and uniformly.

  In the present embodiment, the DO cooking table 741 includes a first data area 741A corresponding to DO cooking using the shallow pot 102 and a second data area 741B corresponding to DO cooking using the deep pot 101. . The recommended range of the set time P is determined according to the type of pan used for DO cooking. The user sets the set time P on the grill operation panel 19 in accordance with the type of pan used for DO cooking. Since CPU71 determines time T1-T4 corresponding to set time P based on DO cooking table 741, it can heat a pan in the combustion mode according to the kind of pan used for DO cooking.

For example, in the DO cooking table 741 shown in FIG. 7, the times T2 to T4 are allocated to a plurality of patterns of the set time P based on the above-described predetermined rules, but can be freely set according to the set time P. It is also possible to allocate to. Since the times T2 to T4 of the DO cooking table 741 can be rewritten freely, it is possible to distribute the time corresponding to the actual cooking.

  Moreover, in the said embodiment, although 180 second is derived | led-out by the experimental result about the initial heating time T1, 180 second is an example, Comprising: Time required for the heating of the pan itself which is DO used with the grill warehouse 20 at least If it is. Further, the time T1 may be different between the first data area 741A and the second data area 741B.
