BACKGROUND OF THE INVENTION
The present invention relates to a gas cooker having a cooking time timer.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, in a gas stove grill, a grill with a timer that automatically extinguishes after a set cooking time has been known. In general, such a grill with a timer is provided with a display panel for displaying the remaining time (or elapsed time) of the timer, and a + switch and a-switch for setting the cooking time to be increased or decreased in minutes. By setting the desired time at the start of the combustion, the fire is automatically extinguished after the set time has elapsed, so that it is possible to reduce the trouble of checking the baking condition during cooking and to constantly stabilize the heating.
[0003]
In addition, such a grill with a timer stores a predetermined cooking time as an initial value in advance, and displays the initial value on the display unit at the start of combustion of the burner, and increases or decreases it using the + switch and the-switch. There are things such as changing the cooking time by correcting. The time required for cooking on the grill is about 4 to 10 minutes without much difference depending on the food to be cooked and its amount, so the initial cooking time is stored as 7 minutes, for example. 7 ”is displayed. Since the cook sets the desired cooking time by operating the + and-switches from the initial value displayed at the start of cooking, the number of operations is less than when the time is set from the state without the initial value, and it takes a setting. Time and effort can be reduced. For example, if you want to set the cooking time to 5 minutes, if there is no initial value, you must press the + button five times, such as 0 → 1 → 2 → 3 → 4 → 5, while the initial value is “ If “7” is displayed, you only need to press the-button twice, such as 7 → 6 → 5.
[0004]
[Problems to be solved by the invention]
However, even if the initial cooking time is stored in advance as described above, the initial cooking time is not always optimal for all users. For example, the initial cooking time is stored as 7 minutes. Regardless, in practice, when the cooking time is frequently used for 5 minutes, it takes time to change the setting, such as reducing the cooking time by 2 minutes each time the food is used.
[0005]
The gas cooker of the present invention has an object to solve the above-described problems and to reduce the labor required for setting the cooking time regardless of the use conditions.

DETAILED DESCRIPTION OF THE INVENTION
In order to further clarify the configuration and operation of the present invention described above, preferred embodiments of the gas cooker of the present invention will be described below. FIG. 1 is an external view of a gas stove as an embodiment of the present invention. This gas stove is provided with an opening / closing door 11 in the approximate center of the front panel 10 and a grill burner 12 for burning and heating cooked food such as fish. Further, on the right side of the front panel 10, an ignition button 13 for igniting and extinguishing the grill burner 12, a heating power adjusting lever 14 for adjusting the amount of combustion of the grill burner 12, and a setting and display of a combustion time timer of the grill part And an operation unit 15 for performing the operation. A battery case 17 that houses the dry battery 16 is provided on the left side of the front panel 10.
[0009]
Next, the structure of the grill part of this gas stove is demonstrated. FIG. 2 is a schematic configuration diagram of the grill portion. The grill portion is sparked by application of a high voltage from the igniter 19, a grill burner 12 that burns gas, a gas supply path 18 for supplying gas to the grill burner 12, an igniter 19 that generates a high voltage. In order to perform notification by the buzzer, the thermocouple 21 that detects misfire of the electrode 20, the grill burner 12, the controller 22 that controls the combustion control, the operation unit 15 that includes the display panel 15a, the + switch 15b, and the -switch 15c. And a dry battery 16 serving as a power source for the igniter 19 and the controller 22. Further, the gas supply path 18 is opened by pressing the ignition button 13 and closed by the next pressing operation. The adsorption valve is opened by being pushed by the ignition button 13 and opened. And a magnet valve 24 for holding the valve. In addition, a switch S1 that is turned on only when the ignition button 13 is pressed during ignition and a switch S2 that is turned on when the ignition button is pressed and turned off when the ignition button 13 is pressed are provided.
[0010]
The controller 22 includes a CPU, RAM, and ROM that form a well-known arithmetic logic circuit (not shown), an input interface that inputs signals from various sensors, an output interface that outputs drive signals to various actuators, and the like. Further, when the thermoelectromotive force generated from the thermocouple 21 exceeds a predetermined value, it is determined that there is ignition, and the magnet valve 24 is energized. When the thermoelectromotive force is below the predetermined value, it is determined that there is no ignition and the energization is stopped. A valve drive circuit is provided. Furthermore, the cooking time timer which starts the countdown from initial cooking time simultaneously with pushing operation by the ignition button 13 is provided. Note that the controller 22 is always energized from the dry battery 16, and enters a sleep state when the appliance is not in use to reduce power consumption.
[0011]
The operation unit 15 displays the initial cooking time on the display panel 15a simultaneously with the pressing operation of the ignition button 13, and then displays the remaining time (minutes) of the cooking time timer corresponding to the passage of time. Also, the cooking time can be adjusted in minutes by the + switch 15b and the-switch 15c.
[0012]
Next, the operation of the gas stove of the present embodiment will be described using the flowchart of FIG. When the ignition button 13 is pressed (S1), the main valve 23 and the magnet valve 24 are mechanically pushed open and gas flows into the grill burner 12, and at the same time, the switches S1 and S2 are turned ON, and the electrode 20 sparks to the grill burner 12. Ignite. Simultaneously with the pressing operation of the ignition button, the initial cooking time (7 minutes) is displayed on the display panel 15a (S2), and the countdown of the cooking time timer is started (S3). When the grill burner 12 starts combustion, the thermocouple 21 is heated to generate a thermoelectromotive force, and when the controller 22 detects a thermoelectromotive force of a predetermined value or more, it is determined that there is ignition and the magnet valve 24 is energized and adsorbed. By maintaining the valve open state, combustion continues even when the ignition button 13 is released. If the thermoelectromotive force of the thermocouple 21 has not risen to a predetermined value or more when the ignition button 13 is released (S4: NO), the magnet valve is not energized and combustion is not continued, causing an error in the display panel 15a. “E” representing that the sound is displayed (S5) and a buzzer is sounded (S16).
[0013]
If the desired cooking time differs from the initial cooking time (7 minutes) displayed on the display panel 15a at the start of cooking, the cooking time is lengthened by pressing the + switch 15b, and the-switch 15c is pressed. The cooking time is adjusted to be short (S6: YES). In this way, the setting mode for setting the current cooking time by increasing or decreasing the cooking time displayed on the display panel 15a corresponds to the first setting mode of the present invention. As soon as the cooking time is adjusted, the cooking time setting timer starts counting down from the set value.
[0014]
When the + switch 15b and the-switch 15c are simultaneously pressed for 10 seconds (S8: YES, S9: YES), the mode changes to the initial cooking time change mode (corresponding to the second setting mode of the present invention). (S10) The initial cooking time (7 minutes) stored in the controller 22 is displayed on the display panel 15a (S11). Here, the displayed value of the initial cooking time can be adjusted by increasing / decreasing it with the + switch 15b and -switch 15c (S12). After the initial cooking time is adjusted, the + switch 15b and the -switch 15c are simultaneously pressed again (S13: YES), and the displayed initial cooking time is newly stored in the controller 22 as the initial cooking time (S14). ). By performing such an operation, the changed initial cooking time is displayed on the display panel 15a from the next cooking. Such a change in the initial cooking time is not limited to during the combustion operation, and the initial cooking time change mode can be achieved by simultaneously pressing the + switch 15b and the -switch 15c for 10 seconds while the combustion operation is stopped. Can enter.
[0015]
When the combustion operation continues and the cooking time timer reaches 0 (S15), a buzzer notifies (S16), and the magnet valve is closed to stop combustion (S17).
[0016]
As described above, according to the gas stove of the present embodiment, since the initial cooking time can be changed to a favorite time, the number of operations required for changing the cooking time when cooking is started can be reduced, which is convenient. . Further, since the change of the initial cooking time shares the operation switches 15b and 15c for adjusting the conventional cooking time, it is not necessary to provide a new switch, and the cost can be reduced. In addition, since the initial cooking time change mode requires that the + switch 15b and the -switch 15c are simultaneously pressed for 10 seconds, it is possible to prevent the initial cooking time from being accidentally changed during normal use. it can.
[0017]
