[0001]
[Field of the Invention]
The present invention relates to a cooking device for cooking grilled fish and the like.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, there is known a gas table provided with a gas stove, for example, and a grill device for cooking a grilled fish or the like. The grill device is composed of a heating chamber (grill chamber) for storing cooked food such as fish and a gas burner (grill burner) provided in the grill chamber. The cooked food is cooked (baked food) by heating.
[0003]
According to the gas table, the user can cook the baked goods such as fish with the grill device at the same time while cooking the simmered food using the gas stove. However, when cooking grilled food with the grill device, the food once stored in the grill cabinet is not easily noticeable by the user, so the user is distracted by the cooked food and forgets to extinguish the grill burner. There is a problem that the food in the grill is likely to be overbaked.
[0004]
In order to solve this problem, a timer is provided to measure the combustion continuation time from the time when the grill burner is ignited, and when the time measured by the timer exceeds a predetermined extinction judgment time, the user forgets to turn off the grill burner. There is known a grill device that performs a forgetting-to-extinguish prevention process that forcibly extinguishes a grill burner. In such a grill apparatus, the forgetting-off determination time is a time range normally required for cooking the grill so that the forgetting-off prevention process is performed during the cooking of the grill and the grill burner is extinguished and the cooking of the grill is not stopped. It was set with a margin for a longer time than the upper limit.
[0005]
However, the actual time required for cooking the grill differs depending on the size and type of the cooked food. Therefore, if the user forgets to extinguish the grill burner after starting the cooking of dried fish, etc., where the cooking of the grill ends in a relatively short time, the grilled food is forcibly extinguished before the grill burner is forcibly extinguished by the forgetting to extinguish process. The time required for cooking was exceeded, and the possibility of overcooking the food was high.
[0006]
[Problems to be solved by the invention]
In view of the above background, an object of the present invention is to provide a cooking device that reduces the possibility of overcooking of a cooked product when the user forgets to stop the heating means.
[0007]
[Means for Solving the Problems]
The present invention has been made in order to achieve the above object, and includes a heating means for heating the food contained in the heating chamber, and a time measuring means for measuring the operation continuation time from the start of operation of the heating means. And an improvement of the heating cooker provided with a forget-to-turn-off preventing means for stopping the operation of the heating means when the operation continuation time of the heating means timed by the time-counting means exceeds a predetermined forgetting-off determination time. .
[0008]
The time required for the cooked product to be baked after the cooked food is cooked by the heating means (hereinafter referred to as necessary heating time) varies depending on the size, amount, or type of the cooked product. For this reason, the determination time for forgetting to turn off is set as the required heating time variation range corresponding to general cooking (raw round fish, raw fillet, dried fish, etc.) means When the cooking time such as dried fish with a short required heating time is cooked, the forgetting to turn off determination time is shorter than the necessary heating time. It can happen that it is much longer.
[0009]
And in this case, if the user forgets to stop the heating means after the start of cooking, it takes a long time to reach the forgetting to turn off time after the necessary heating time of the cooked food, There is an inconvenience that the cooked food is overbaked before the operation of the heating means is stopped by the forgetting-off prevention means.
[0010]
Therefore, in order to prevent such inconvenience, the present invention provides a determination time selection means for instructing selection of the forgetting-off determination time in accordance with a user operation, and in response to an instruction from the determination time selection means. , The time to forget to erase The required heating time variation range corresponding to a general cooked food is a time required for the cooked food to be baked after the cooking by the heating means is started. Determination time setting means for switching between a first determination time longer than the upper limit and a second determination time shorter than the first determination time is provided.
[0011]
According to this invention, when cooking, the user can select the determination time to forget to turn off according to the required heating time of the food by operating the determination time selection means. And when cooking the food with a short required heating time, by setting the second determination time as the forgetting-off determination time, the forgetting-off determination time is set close to the required heating time. Thus, when the user forgets to stop the heating means, the possibility of overcooking the food can be reduced.
[0012]
In addition, when the user forgets to select the forgetting-off determination time by the determination time selection means and performs cooking of the food having a short required heating time, the forgetting-off determination time is set to the first determination time. When the state is set, the forgetting to turn off determination time may be much longer than the necessary heating time. In this case, if the user forgets to stop the operation of the heating means after the start of cooking, the cooking is continued even after the necessary heating time has elapsed, and the heating means is operated by the forgetting to turn off preventing means. There is the inconvenience that the food is over-baked before it is stopped.
[0013]
Therefore, in order to deal with such inconvenience, the present invention provides the determination time setting means that sets the forgetting to turn off determination time regardless of whether or not there is an instruction from the determination time selection means at the start of operation of the heating means. 2 is forcibly set to a determination time.
[0014]
According to this invention, when the user forgets to select the forgetting to turn off determination time when starting cooking, the forgetting to turn off determination time is forcibly set to the second determination time. Kept in a state. For this reason, when cooking a cooked food having a short required heating time, the possibility of the forgetting to turn off determination time being extremely longer than the required heating time is reduced, thereby allowing the user to use the heating means. When the stop operation is forgotten, the possibility of overcooking the food can be reduced.
[0015]
In addition, the user does not realize that the determination time forgetting to be erased is forcibly set to the second determination time by the determination time setting means, and the required heating time is longer than the second determination time. When cooking an object, the operation of the heating means is stopped by the forgetting-off preventing means during the cooking, and the cooking is terminated in the middle of the user's will. Arise.
[0016]
Therefore, there is provided an informing means for notifying a user that the forgetting-off determination time is set to the second determination time by the determination time setting means.
[0017]
According to the present invention, the notification means notifies the user that the determination time for forgetting to be erased is forcibly set to the second determination time. The user can be prompted to set the forgetting-off determination time according to the required heating time. When the user cooks the cooked food whose required heating time is longer than the second determination time, the determination time selection means changes the forgetting-off determination time from the second determination time to the first determination. By switching to the time, it is possible to prevent the inconvenience that the operation of the heating unit is stopped by the forgetting-off preventing unit during cooking.
[0018]
Further, immediately after the cooking is finished and the operation of the heating means is stopped, the temperature in the heating chamber is in a raised state. And when heating cooking is started in a state where the temperature in the heating chamber is increased in this way, the necessary heating of the cooked food is required compared to when cooking is started in a state where the temperature in the heating chamber is lowered (about room temperature). Time is shortened.
[0019]
Therefore, the present invention provides a determination time for performing correction to shorten the first determination time and the second determination time when the operation of the heating unit is resumed within a predetermined time after the operation of the heating unit is stopped. A correction means is provided.
[0020]
According to the present invention, after the operation of the heating unit is stopped, when the operation of the heating unit is resumed within the predetermined time, that is, the temperature in the heating chamber is increased and the required heating time is shortened. When the operation of the heating unit is resumed, the first determination time and the second determination time are shortened by the determination time correction unit. Therefore, when cooking is started in a state where the temperature in the heating chamber has risen and the required heating time has been reduced, the possibility of the forgetting to turn off determination time being longer than the required heating time is reduced. Thus, when the user forgets to stop the heating means, the possibility of the cooked food being overbaked can be reduced.
[0021]
The heating means includes an upper heating means for heating the food contained in the heating chamber from above and a lower heating means for heating the food from below, and the food is heated with the upper heating means and the Selection to selectively execute one-sided heating for heating one of the lower heating means and double-sided heating for heating the cooked food by both the upper heating means and the lower heating means in accordance with a user instruction A heating control unit, wherein the determination time setting unit determines the first determination time and the second determination time when the double-sided heating is performed as the first determination time and the second determination time when the single-sided heating is performed. It is characterized in that each is set to a shorter time.
[0022]
When performing the double-sided cooking, the amount of heating for the cooked food is greater than when performing the single-sided cooking, and thus the required heating time is shortened. Therefore, by the determination time setting means, the first determination time and the second determination time when the double-sided heating is performed are shorter than the first determination time and the second determination time when the single-sided heating is performed. By doing so, the possibility that the forgetting to turn off determination time may be longer than the required heating time when performing the double-sided heating can be reduced. Thereby, when a user forgets the stop operation of the said heating means, possibility that this cooked food will be overbaked can be reduced.
[0023]

[0031]
The upper burner 21, the lower burner 22, the left stove burner 26, and the right stove burner 27 include ignition electrodes 34, 35, 36, and 37, and thermocouples 38 for detecting the combustion state of each burner, respectively. 39, 40, and 41 are provided.
[0032]
The gas table 1 includes a left stove 2, a right stove 3, and a controller 50 that controls the combustion operation of the grill device 4. The controller 50 is an electronic unit composed of a CPU, ROM, RAM and the like, and includes a combustion control means 51 (including the function of the selective heating control means of the present invention), a timer 52 (corresponding to the time measuring means of the present invention), A forgetting-off prevention unit 53, a determination time setting unit 54, and a determination time correction unit 55 are provided.
[0033]
The combustion control means 51 controls the combustion operation of the left stove 2, the right stove 3, and the grill device 4. Further, the forgetting-off prevention means 53, together with the timer 52, the determination time setting means 54, the determination time correction means 55, and the combustion control means 51, within the above-mentioned forgetting to turn-off determination time after the grill device 4 starts the combustion operation. When the user does not perform the fire extinguishing operation of the grill device 4, the forget-to-extinguishment prevention process is performed in which the combustion operation of the grill device 4 is forcibly stopped at the end of the forgetting-off determination time.
[0034]
The controller 50 is connected to ignition / fire extinguishing switches 70, 71, 72 and thermocouples 38, 39, 40, 41 that are turned on / off in response to the pressing operation of the ignition / fire extinguishing buttons 7, 8, 9 by the user. The The combustion control means 51 recognizes the operation state of the ignition / fire extinguishing buttons 7, 8, 9 by detecting the ON / OFF state of the ignition / fire extinguishing switches 70, 71, 72.
[0035]
Further, the controller 50 is connected to the electromagnetic valves 30, 32, 33 and the ignition electrodes 34, 35, 36, 37. Then, the combustion control means 51 performs opening / closing control of the electromagnetic valves 30, 32, 33 by switching between energization and cutoff of the electromagnetic valves 30, 32, 33.
[0036]
When using the grill device 4, the user first presses the ignition / fire extinguishing button 7 to perform the ignition operation of the grill device 4. In response to this ignition operation, the ignition / fire extinguishing switch 70 is turned on, and the combustion control means 51, which has recognized that it has been turned on, applies a high voltage to the ignition electrodes 34 and 35 to cause spark discharge, By opening the solenoid valve 30 and starting the supply of fuel gas to the upper burner 21 and the lower burner 22, the upper burner 21 and the lower burner 22 are ignited.
[0037]
When the user operates the thermal power adjustment knobs 10a and 10b, the opening degree of the thermal power control valves 31a and 31b is changed accordingly, and the thermal powers of the upper burner 21 and the lower burner 22 are respectively three of strong thermal power, weak thermal power, and fire extinguishing. Adjusted to the stage. When the heating power adjustment knob 10a is operated to the fire extinguishing position, the one side of the food F is heated only by the lower burner 22, and when the heating power adjustment knob 10b is operated to the fire extinguishing position, the food only by the upper burner 21 is used. One side heating of F is performed.
[0038]
Further, when both of the heating power adjustment knobs 10a and 10b are operated to the strong heating power position or the low heating power position, both-side heating of the cooked food (fish F) by the upper burner 21 and the lower burner 22 is performed. The heating power adjustment knobs 10a and 10b are configured such that when one is in the fire extinguishing position, the other cannot be operated to the fire extinguishing position.
[0039]
Further, the thermal power adjustment knobs 10a and 10b have switches 73 and 74 that are turned on when the thermal power adjustment knobs 10a and 10b are at the fire extinguishing position and are turned off when the thermal power adjustment knobs 10a and 10b are at positions other than the fire extinguishing position (low thermal power, strong thermal power). Each is built-in. The switches 73 and 74 are connected to the controller 50. The controller 50 detects the ON / OFF state of the switches 73 and 74, so that the heating state of the grill device 4 is either double-sided heating or single-sided heating. Recognize
[0040]
When the user presses the ignition / extinguishing button again to perform the extinguishing operation, the ignition / extinguishing switch 70 is turned off, and the combustion control means 51 that recognizes the off state closes the electromagnetic valve 30. The supply of the fuel gas to the upper burner 21 and the lower burner 22 is stopped, and the combustion of the upper burner 21 and the lower burner 22 is stopped.
[0041]
Here, the user usually starts cooking on both sides of the food F such as fish by the grill device 4 or heating cooking (baked food cooking) by single-sided heating, and then cooks the food while checking the cooking condition of the food F. When it is determined that the food F has been baked, the ignition / extinguishing button 7 is pressed to perform a fire extinguishing operation, and the combustion operation of the grill device 4 is stopped.
[0042]
However, as shown in FIG. 1, since the inside of the grill device 4 is difficult to see, especially when the left stove 2 and the right stove 3 are used together with the grill device 4, the user places the left stove 2 on the left stove 2. It is easy to forget that the cooked food is cooked by the grill device 4 while being distracted by the cooked food. And when forgetting that cooking is performed by the grill device 4 and failing to stop the combustion of the grill device 4, there is an inconvenience that the food F is baked too much.
[0043]
Therefore, the controller 50 according to the present embodiment prevents the overcooking of the food F when the user forgets to stop the combustion of the grill device 4 as described above. It is carried out.
[0044]
Hereinafter, the forgetting to turn off prevention process of the grill device 4 will be described in detail with reference to the flowcharts of FIGS. 4 and 5.
[0045]
Referring to FIG. 4, STEP 1 to STEP 2 are processes by determination time setting means 54. When the combustion control means 51 performs ignition processing of the upper burner 21 and the lower burner 22 and the combustion operation of the grill device 4 is started, the determination time setting means 54 proceeds from STEP1 to STEP2 and proceeds to the first determination time and the first determination time. 2 The determination time is set to a time corresponding to double-sided heating according to the data table of FIG. When performing double-sided heating, the amount of heating is greater than when performing single-sided heating, and naturally the required heating time is shortened.
[0046]
Therefore, as shown in the data table of FIG. 3A, the determination time setting means 54 has a shorter forgetting-off prevention determination time when double-sided heating is performed than a forget-to-delete determination time when single-sided heating is performed. Set to time. In addition, in the data table of FIG. 3A, the first determination time is to prevent the cooking process from being forgotten by executing the forgetting to erase process in the middle of the cooking process. Fluctuation range of required heating time corresponding to general cooked food (raw raw fish, fillet fish, dried fish, etc.) Go It is set with a margin for a time longer than the upper limit. On the other hand, the second determination time is shorter than the first determination time, and is set on the assumption that the necessary time such as dried fish is relatively short.
[0047]
The subsequent STEP 20 to STEP 21 branched from STEP 3 to STEP 4 and STEP 3 are processes by the determination time correction means 55. The determination time correction means 55 branches from STEP 3 to STEP 20 when the ignition process of the grill device 4 is performed within a predetermined time T (minutes) from the previous combustion stop. Then, the determination time correction unit 55 performs correction for reducing the first determination time and the second determination time in STEP 20.
[0048]
In this correction, when cooking time is started with the elapsed time from the previous combustion stop being short and the temperature in the grill cabinet 20 still high, the cooking is performed with the temperature in the grill cabinet 20 being at room temperature. This is done in consideration of the fact that the required heating time is shorter than when it was started. Specifically, the determination time correction unit 55 shortens the first determination time and the second determination time by resetting the first determination time and the second determination time in accordance with the data table shown in FIG. To do.
[0049]
Thus, the determination time correction means 55 performs correction to shorten the first determination time and the second determination time, so that the first determination time and the second determination time are set according to the actual change in the required heating time. Can be changed. Then, the determination time correction means 55 sets (= 1) the correction flag (correction F in the figure) at STEP 21 when the first determination time and the second determination time are corrected, and STEP 4 when no correction is performed. To reset the correction flag (= 0).
[0050]
Subsequent STEP 5 to STEP 7 are processes by the determination time setting means 54. The determination time setting means 54 sets the initial setting of the forgetting-off determination time in STEP 5 as the second determination time set to a short time, and notifies the user that the forgetting-off determination time is set as the second determination time in STEP 6. In order to do this, the short-time lamp 14 is turned on, and a short-time flag (short-time F in the figure) indicating that the forgetting-to-turn-off determination time is set to the second determination time is set (= 1).
[0051]
Thus, when the user forgets to select the forgetting to turn off determination time by setting the initial setting of the forgetting to turn off determination time to the second determination time shorter than the first determination time, the necessary heating of the cooked food The possibility that the forgetting to turn-off determination time becomes longer than the time is reduced, thereby reducing the possibility of overcooking of the cooked food when the user forgets to extinguish the grill device 4. .
[0052]
Further, by turning on the short-time lamp 14, it is possible to notify the user that the forgetting to turn off determination time is set to the second determination time, and to prompt the user to select the forgetting to turn off determination time. Then, the determination time setting means 54 starts the timer 52 at STEP8, and thereafter, the loop of STEP9 to STEP12 exceeds the determination time for the timer 42 to forget to turn off at STEP11, or the user ignites / extinguishes at STEP12. It is repeatedly executed until it is recognized that the button 7 (see FIG. 1) has been extinguished.
[0053]
STEP 30 to STEP 36 branched from STEP 9 and STEP 9 are processing of the determination time setting means 54 when the selection switch 13 is operated by the user. The determination time setting unit 54 switches and sets the forgetting-off determination time between the first determination time and the second determination time every time the user operates the selection switch 13 for determining the forgetting-off determination time.
[0054]
That is, when the user operates the selection switch 13 for determining whether to forget to erase, the process branches from STEP 9 to STEP 30, and the determination time setting means 54 is set when the short time flag (short time F) is set (= 1) ( When the forgetting-off determination time is set to the second determination time), the process branches from STEP 30 to STEP 34, the forgetting-off determination time is switched to the first determination time, and the short time lamp 14 is turned off at STEP 35. In step 36, the short time flag is reset (= 0).
[0055]
When the short-time flag is reset (= 0) in STEP 30 (when the forgetting-off determination time is set to the first determination time), the process proceeds from STEP 30 to STEP 31, and the determination time setting means 54 The forgetting to turn off determination time is set as the second determination time, the short time lamp 14 is turned on in STEP 32, and the short time flag is set (= 1) in STEP 33.
[0056]
Thus, by selecting the forgetting-off determination time according to the required heating time of the food, the forgetting-off determination time closer to the required heating time of the food to be cooked is set. It is possible to reduce the possibility that over-baking will occur or that the combustion operation of the grill device 4 is stopped due to execution of the forget-to-extinguish prevention process during cooking. In addition, by allowing the user to select the forgetting to turn-off determination time in this manner, it is possible to make the user aware of performing the combustion stop operation of the grill device 4, thereby causing the user to forget the combustion stop operation of the grill device 4. The effect which prevents is obtained.
[0057]
STEP 40, STEP 41, STEP 45, STEP 43, STEP 44, and STEP 47 branched from the subsequent STEP 10 and STEP 10 are processes by the determination time setting means 54, and STEP 42 and STEP 46 are processes by the determination time correction means 55.
[0058]
In STEP 10, when the heating state of the grill device 4 is changed from double-sided heating to single-sided heating, or from single-sided heating to double-sided heating, it is recognized from the ON / OFF state of the switches 73 and 74 built in the thermal power adjustment knobs 10a and 10b. The determination time setting means 54 branches from STEP 10 to STEP 40. Then, when the heating state of the grill device 4 changes from single-sided heating to double-sided heating, the determination time setting unit 54 branches from STEP40 to STEP45, and the first determination time according to the data table shown in FIG. Is set to 9 minutes, and the second determination time is set to 15 minutes.
[0059]
On the other hand, when the heating state of the grill device 4 changes from double-sided heating to single-sided heating, the process proceeds from STEP 40 to STEP 41, and the determination time setting means 54 sets the first determination time to 24 according to the data table shown in FIG. Minutes, and the second determination time is set to 15 minutes.
[0060]
Then, when the correction flag (correction F) is set (= 1) in the next STEP 42, that is, the heating cooking being performed is started before the predetermined time T (minutes) has elapsed since the previous combustion stop. If it is, the process branches to STEP 46, and the determination time correction means 55 determines the first determination time and the second determination time according to the data table shown in FIG. Make corrections to shorten.
[0061]
The next STEP 11 and STEP 50 branched from STEP 11 are processing by the forgetting to erase preventing means 53. The forgetting-off prevention means 53 determines whether or not the measurement time of the timer 42 after the start of the timing operation in STEP 8 has exceeded the forgetting-off determination time, and the measurement time of the timer 42 has exceeded the forgetting-off determination time. At that time, the process branches to STEP 50 and instructs the combustion control means 51 to stop the combustion of the grill device 4.
[0062]
Then, the combustion control means 51 closes the electromagnetic valve 30 in response to the combustion stop instruction from the forgetting to turn off prevention means 53 to stop the supply of fuel gas to the upper burner 21 and the lower burner 22, and the grill device 4 Stop the combustion operation. Thereby, when the user forgets to stop the combustion operation of the grill device 4, the combustion operation of the grill device is forcibly stopped.
[0063]
Here, as described above, the forgetting to turn off determination time is selected by the user according to the necessary heating time of the food to be cooked, and also according to the temperature in the grill 20 at the start of the double-sided / single-sided heating and cooking. Since it is set and corrected, the forgetting to turn off determination time is set in the vicinity of the necessary heating time of the food. For this reason, the possibility that the forgetting to turn off determination time is set to a time extremely longer than the necessary heating time of the food is reduced, and when the user forgets to stop the combustion of the grill device 4, the forgetting to turn off preventing means 53. Therefore, the possibility that the cooked food will be overbaked before the combustion stop instruction of the grill device 4 is given can be reduced.
[0064]
Further, when the combustion control means 51 detects in STEP 12 that the switch 70 has been turned off and recognizes that the ignition / extinguishing operation of the ignition / extinguishing button 7 of the grill device 4 has been performed, the combustion control means 51 turns on the solenoid valve 30. The supply of fuel gas to the upper burner 21 and the lower burner 22 is stopped by closing the valve, the upper burner 21 and the lower burner 22 are extinguished, and the combustion operation of the grill device 4 is stopped.
