Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a heating cooker having a timer cooking function for a grill, which operates a heating means provided in a grill cabinet for a predetermined time to cook a grilled food.
[0002]
[Prior art]
For example, a composite gas stove equipped with a grill has a so-called timer cooking function that burns a grill burner according to a time set in a timer.
[0003]
In this type of gas stove, the user can set the heating time corresponding to the cooking time of the food to the timer, and grill cooking with a desired heating time can be performed.
[0004]
By the way, an upper limit is set for the time that the user can set in the timer, and it cannot be set beyond the upper limit time (for example, 15 minutes). In grill cooking of normal food such as raw fish, it is said that cooking can be performed by heating for a relatively short time (for example, about 8 minutes). This is because the overheating of the object may cause excessive burning and cause a cooking failure.
[0005]
However, in rare cases, a cooked food (for example, a shochu) that needs to be heated for a relatively long time exceeding the upper limit of the timer setting time described above may be cooked. In this case, annoying operations such as unintentionally setting the timer setting time to the upper limit at the start of cooking and setting the grill burner ignition and timer time again after the grill burner has been extinguished at the upper limit time. There was an inconvenience that the grill had to be used during cooking and the usability of the grill was poor.
[0006]
[Problems to be solved by the invention]
In order to eliminate such inconvenience, the present invention can extend the set time of the timer in advance corresponding to a cooked food having a relatively long cooking time, and an object thereof is to provide a user-friendly heating cooker, It is another object of the present invention to provide a cooking device capable of suppressing an excessive temperature rise in the grill box even if the operation time of the heating means is extended according to the set time of the extended timer.
[0007]
[Means for Solving the Problems]
In order to achieve such an object, the present invention provides a grill for cooking a cooked food in a cabinet, a heating means for heating the cooked food provided in the grill cabinet, and operating the heating means for a set time. In a heating cooker comprising a timer and timer setting means for setting a time measurement time of the timer with the first predetermined time as an upper limit, the first predetermined time by the timer setting means is extended and a second predetermined time is set. Rutotomoni provided a timer time extension means for setting the count time of the timer time as an upper limit, when by extending the first predetermined time has timed time of the timer set by the timer time extension unit, the heating unit A heating control means for reducing the amount of heating is provided .
[0008]
The timer setting means sets a time measuring time with the first predetermined time as an upper limit. The timer time extending means sets a time measuring time by extending the first predetermined time and setting the second predetermined time as an upper limit. The heating means stops heating the cooked food after operating for the set time according to the set time of the timer by the timer setting means or the timer time extending means.
[0009]
In general, the first predetermined time is a maximum heating time in which a cooked food (eg, raw fish) that performs normal grill cooking does not fail due to excessive burning due to overheating. On the other hand, the second predetermined time differs from a cooked food (eg, raw fish) that performs normal grill cooking when the cooked food (eg, grilled salmon) that requires a longer time than the first predetermined time is used. This is the maximum time during which the cooked product does not fail due to overheating due to overheating.
[0010]
By providing the timer time extension means, it is possible to set the timer time corresponding to the food whose cooking time exceeds the first predetermined time at the start of cooking. The trouble of re-setting can be eliminated. Even when the timer time is extended by the timer time extension means, the extended time can be grilled with the second predetermined time as an upper limit, and is longer than the first predetermined time. Can be cooked (e.g., baked rice cake), and cooking failure of the cooked product (e.g., baked rice cake) can be prevented.
Furthermore, in the present invention, even when the timer time extension means is set to extend the time count of the timer, and the heating means is operated for a relatively long time, the heating control means controls the heating amount of the heating means. Since it is reduced, it can suppress that the inside of a grill warehouse becomes high temperature too much, and can prevent the overheating of a foodstuff.
[0011]
In the present invention, the timer setting means can set the time by performing an operation to increase or decrease the time of the timer by an operation switch for setting the time of the timer, and the timer time extension means can set the time When a predetermined operation different from the operation of increasing or decreasing the time measured by the switch is performed, the first predetermined time can be extended to set the time measured by the timer.
[0012]
According to the present invention, when the user performs an increase / decrease operation of the timer time by the operation switch (hereinafter referred to as normal operation), the timer setting means sets the timer time according to the operation of the operation switch. Set. When the user performs a predetermined operation different from the operation of increasing or decreasing the time measured by the timer using the operation switch (hereinafter referred to as a special operation), the timer time extending means sets the first predetermined time. It is possible to set a timer counting time that exceeds.
[0013]
As described above, since the timer time exceeding the first predetermined time cannot be set unless a special operation is performed by the operation switch, the timer time exceeding the first predetermined time cannot be set carelessly. It can be prevented from being performed.
[0014]
In addition, when cooking food (for example, raw fish etc.) as normal grill cooking, the user should just perform normal operation by the said operation switch, and the food which requires time longer than 1st predetermined time. When cooking (for example, grilled rice cake), a special operation by the operation switch may be performed, so that a timer can be easily set according to the food.
[0017]
Further, in the present invention, temperature detection means for detecting the heating temperature of the cooked food is provided, and the heating control means is operable within the operation time by the timer when the temperature detected by the temperature detection means exceeds a predetermined temperature. Even so, the heating of the heating means is stopped.
[0018]
By providing the temperature detecting means, it is possible to easily detect that the inside of the grill has become excessively hot. And, if the heating control means stops heating the heating means when the temperature detected by the temperature detection means becomes excessively high, overheating of the food can be reliably prevented. .
[0019]

The operation panel 8 is provided with a timer remaining time indicator 31 for displaying the remaining time of the grill timer 25 by the output of the display control means 22. Although not shown, in addition to the + key switch 29, the -key switch 30 and the timer remaining time indicator 31, the operation panel 8 is provided with various operation switches for instructing the operation of the burner burners 2 and 3. I'm.
[0027]
Next, the operation | movement in the timer cooking of the grill 4 is demonstrated. The timer control means 21 executes the processing flow of FIG. 3 when the user performs an ignition operation on the grill knob 4 (see FIGS. 1 and 2) and the ignition processing for the grill 4 is performed. On the other hand, the grill control means 20 executes the processing flow of FIG. 4 from the start of operation of the grill 4.
[0028]
First, as shown in FIG. 3, when the ignition process for the grill 4 is performed, the timer control unit 21 recognizes that the grill burner 9 has been ignited by the output from the grill control unit 20, and then the steps 1 to 6 are performed. Perform initial processing. That is, the setting flag Fa is reset (= 0) in STEP1, and the extension flag Fb is reset (= 0) in STEP2. Next, proceeding to STEP 3, 15 minutes (first predetermined time) is set as the upper limit L of the set time of the grill timer 25. In STEP 4, 8 minutes within the first predetermined time is initially set as the remaining time of the set time of the grill timer 25 (denoted as GTM in the flowchart), and the count down of the grill timer 25 is started in STEP 5. Remaining time of the 8 minutes is a standard cooking time in the cooking by grill 4, by the initial remaining time of such standard cooking time in advance grill timer 25, timer cooking time of a user This is for convenience of setting. The time of 15 minutes was made the upper limit L is in conducting standard grill is the time to prevent cooking failure caused by excessive heating of the food A. In subsequent STEP 6, the remaining time of the grill timer 25 (8 minutes at this time) is displayed on the timer remaining time display 31.
[0029]
The following STEP 7 to STEP 11 are processes when the user operates the + key switch 29 (shown in FIG. 2). When the operation of the + key switch 29 by the user is detected in STEP 7, the process proceeds to STEP 8, and when the remaining time of the grill timer 25 is not the upper limit L, the remaining time of the grill timer 25 is increased by 1 minute in STEP 9. In subsequent STEP 10, if the remaining time of the grill timer 25 exceeds 15 minutes, the process proceeds to STEP 11, and if not, the process proceeds to STEP 15 described later. This STEP 10 determines whether or not the timer time has been extended by a special operation, and the extension of the timer time will be described later. In STEP 11, the setting flag Fb is set (= 1) and the process proceeds to STEP 15 described later.
[0030]
STEP 12 to STEP 14 are processes when the user operates the -key switch 30 (shown in FIG. 2). If the operation of the + key switch 29 is not detected in STEP7, the process branches to STEP12. If the operation of the -key switch 30 by the user is detected in STEP12, the process proceeds to STEP13. In STEP13, when the remaining time of the grill timer 25 at this time is 1 minute which is the minimum, the process proceeds to STEP15. Otherwise, in STEP14, the remaining time of the grill timer 25 is decreased in units of 1 minute.
[0031]
In STEP15, when the extension flag Fb is not set, the process proceeds to STEP18. When it is detected at STEP 15 that the extension flag Fb is set, the extension flag Fb is reset at STEP 16, and further at STEP 17, the timer 25 for grill 25 is displayed by the timer remaining time display 31 via the display control means 22. Is displayed and the process proceeds to STEP18.
[0032]
In STEP 18, it is determined that an operation (special operation) different from the operation of increasing or decreasing the remaining time of the grill timer 25 is performed by the user using the + key switch 29 and the −key switch 30. In the present embodiment, when the special operation detecting means 28 detects that the + key switch 29 and the -key switch 30 are simultaneously operated (pressed) for 1 second or more in STEP 18 and the special operation is confirmed, steps 19 to 19 are performed. The process of STEP 22 is performed, and if no special operation is detected by the special operation detecting means 28, the process proceeds to STEP 23.
[0033]
In STEP 19, the extension flag Fb is set, and the routine proceeds to STEP 20, where the one-minute timer 32 (shown in FIG. 2) provided in the timer time extension means 27 is started. As will be described later, if the + key switch 29 is operated before the 1-minute timer 32 times out, the remaining time of the grill timer 25 that exceeds the upper limit of 15 minutes in the initial setting can be set.
[0034]
In subsequent STEP 21, 30 minutes (second predetermined time) is set as the upper limit L of the set time of the grill timer 25, and the process proceeds to STEP 22 where the remaining time of the grill timer 25 is flashed and displayed by the timer remaining time display 31. . The upper limit L at this time, which is 30 minutes, is the maximum time during which the grill burner 9 can be used. If this time is exceeded, the temperature in the grill box becomes extremely high, which is not preferable.
[0035]
By now by blinking indication according to the timer remaining time indicator 31 is made, the user can confirm that the special operation is enabled.
[0036]
Subsequently, in STEP23, when the remaining time of the counted down timer 25 is 0, the process proceeds to STEP29, where the grilling control means 20 closes the original electromagnetic valve 10 and the fire extinguishing process is performed. I do.
[0037]
On the other hand, if the remaining time of the grill timer 25 is not yet 0 in STEP 23, the process branches to STEP 7. When neither the operation of the + key switch 29 nor the operation of the −key switch 30 is detected in STEP7 and STEP12, the process proceeds to STEP24. In STEP 24, if the extension flag Fb is set, the process proceeds to STEP 25. If the one-minute timer 32 provided in the timer time extending means 27 has not expired, the process proceeds to STEP 18. When the time-up of the 1-minute timer 32 is detected in STEP 25, the extension flag Fb is reset in STEP 26, and 15 minutes (first predetermined time) is set as the upper limit L of the setting time of the grill timer 25 in STEP 27. To do. Next, in STEP 28, the current remaining time of the grill timer 25 is displayed from the timer remaining time display 31, and the process proceeds to STEP 18.
[0038]
When the operation of the + key switch 29 is detected in STEP 7 before the time-up of the one-minute timer 32 is detected in STEP 25, the remaining time of the grill timer 25 is the upper limit L of the set time in STEP 21. If it is 30 minutes or less, the remaining time of the grill timer 25 can be set by the timer time extension means 27. That is, in Step 10, since the remaining time of the grill timer 25 exceeds 15 minutes, the process proceeds to STEP11, the setting flag Fa is set, and the process proceeds to the above-described STEP18 and subsequent steps.
[0039]
On the other hand, as shown in FIG. 4, when the operation of the grill 4 is started, the grill control means 20 first performs a process of opening the bypass solenoid valve 12 by STEP 31 if the setting flag Fa is set, by STEP 31. If the setting flag Fa is not set, STEP 33 performs processing to close the bypass solenoid valve 12. As shown in FIG. 2, when the bypass solenoid valve 12 is closed, the combustion amount of the grill burner 9 becomes small. The setting flag Fa is set in the above-described STEP 11 (shown in FIG. 3) when the setting of the remaining time of the grill timer 25 exceeding 15 minutes (extension of the setting time) is performed. That is, when the remaining time of the grill timer 25 is extended beyond 15 minutes, the combustion time of the grill burner 9 exceeds 15 minutes, and the risk of overheating of the food A increases. Therefore, the grill control means 20 confirms that the remaining time of the grill timer 25 has been extended by the setting flag Fa, and if the setting flag Fa is set, to prevent overheating of the food A. Further, it is assumed that the combustion amount of the grill burner 9 is small.
[0040]
As shown in FIG. 2, the grill control means 20 monitors the temperature of the food A by the temperature sensor 18, and as shown in FIG. 4, the detected temperature (TH) of the temperature sensor 18 in STEP 34. When the temperature becomes abnormal, that is, excessively high, the fire extinguishing process is performed at STEP 35, and then the buzzer 24 is notified at STEP 36 to stop grill cooking.
[0041]
In this embodiment, when the + key switch 29 and the -key switch 30 are simultaneously pressed for 1 second or longer, the special operation detecting unit 28 detects the special operation as a special operation. As described above, the special operation detecting means 28 may be used.
[0042]
In the present embodiment, the heating cooker that employs the grill burner 9 that heats the cooked food A by burning fuel gas as the heating means has been described. However, heating using other types of heating means, for example, an electric heater, is shown. The present invention can also be applied to a cooking device.
