In the above-mentioned conventional gas stove device, when the burner is ignited in a state where cooking utensils are not placed on the burner, the burner is not ignited even when a normal ignition operation is performed, and then the burner is ignited by pressing the forced ignition switch. . For this reason, the burner is not ignited by the habitual ignition operation of pressing the ignition button, and the burner is ignited by pressing the forced ignition switch, which is completely different from the normal ignition operation, so it is very inconvenient. . In particular, since the cookware is not placed on the burner, it is felt as if a spark generated by ignition is suddenly generated, so that the feeling of use is very bad.

Then, in view of the above problems, an object of the present invention is to provide a gas stove device in which the burner is ignited without inconvenience when no cooking utensils are placed on the burner.

In order to solve the above problem, the gas stove device according to the present invention includes a pot bottom sensor for detecting that the cooking utensils are placed on the burner, and the pan bottom sensor does not detect that the cooking utensils are placed on the burner. A gas stove apparatus provided with ignition prohibition means for prohibiting ignition of a burner when an ignition operation is performed on a burner, comprising: a control unit for controlling ignition of the burner; and a power switch turned on during the ignition operation A forced ignition switch is installed, which is configured to start energization to the control unit when the power switch is turned on, and a forced ignition switch is installed that turns on only while a pressing operation is performed in a energized state, and the forced ignition switch is pressed When the ignition operation is performed in a continuous state, and the forced ignition switch is in the on state when the control unit is energized by turning on the power switch, the ignition prohibition is released by the ignition prohibition means to release the ignition prohibition. It is characterized in that it permits ignition of the burner.

The forced ignition switch is not ignited by the forced ignition switch alone, but is operated by pushing the forced ignition switch as a thorough aid to the ignition operation, and the same operation as the normal ignition operation is performed while the forced ignition switch is being pressed. energization is started, and the control unit permits ignition of the burner when the forced ignition switch is in the on state at the time when the energization is started.

And, after ignition, the pot bottom sensor is provided with a temperature sensor for detecting the pot bottom temperature of the cooking utensil, and increases or decreases the heat of the burner to set the pot bottom temperature to any one of a plurality of preset temperatures. High temperature mode that has a control function and sets the pot bottom temperature to the highest temperature within the plurality of set temperatures by continuously pressing and operating the forced ignition switch for a predetermined time after ignition is ignited while the forced ignition switch is pressed It may be configured to implement

At that time, when the ignition operation is performed without pressing the forced ignition switch while the cooking utensils are placed on the burner, the pot bottom temperature is set to the set temperature for normal cooking within the preset temperature. As set, if the pressing operation of the forced ignition switch is released before the predetermined time elapses after ignition is performed in a state in which the forced ignition switch is pressed, the normal mode may be set.

On the other hand, it is also possible to perform the ignition operation in a state in which the forced ignition switch is pressed, and to ignite the burner when a predetermined time has elapsed while the pressing operation of the forced ignition switch is continued.

As described above, the present invention permits ignition of a burner by performing a normal ignition operation while the forced ignition switch is pressed. The burner is ignited without any delay.

Fig. 2 is a block diagram showing a gas pipeline to a burner.
Fig. 3 is a block diagram showing the configuration around the control unit.
4 is a diagram illustrating a control process by a control unit.

Referring to Figure 1, 1 is a gas stove apparatus according to the present invention. The top plate 11 of this gas stove apparatus 1 is provided with two left and right burners 12. As shown in FIG. Both burners 12 have an annular shape, and a pot bottom sensor 13 extending from below to upward is provided in the central space. A temperature sensor is built in the upper end of the pot bottom sensor 13, and it is maintained to freely move in the vertical direction while being biased upward. When, for example, a frying pan FP is placed above the burner 12 as a cooking utensil, the upper end of the pot bottom sensor 13 moves downward while being in close contact with the pot bottom B of the frying pan FP by the bias force. will be pressed down

In this way, when cooking is started while the frying pan FP is placed, the ignition button 2 is pressed. Then, the burner 12 is ignited and cooking can be started. In addition, a thermocouple 14 is disposed in the vicinity of the burner 12, and by detecting the flame of the burner 12 with the thermocouple 14, the ignition of the burner 12 and the occurrence of burnout can be detected. can In addition, reference numeral 10 denotes a battery box, and is configured to supply operating power of the gas stove device 1 to a battery housed in the battery box 10 .

A forced ignition switch 3 is installed above the ignition button 2 . This forced ignition switch 3 is a switch for permitting ignition of the burner 12 even when no cooking utensils are placed on the burner 12, and is operated by pressing, for example, when "roasting" is performed. . "Roasting" refers to an operation such as, for example, baking seaweed in a state where cooking utensils are not placed. In addition, this forced ignition switch 3 is operated by pressing even during "high-temperature stir-fry" cooking.

"High-temperature stir-fry" cooking is cooking in which the temperature of the bottom of the pot (B) is usually high enough to boil without water. This applies to fried foods, etc. And, 31 is an LED.

Referring to FIG. 2 , when the fire extinguishing button 2 is pressed, the operation lever 22a of the heat control device 22 is pushed into the heat control device 22 . Two micro switches (SW1, SW2) not shown in the figure are installed in the heat control device 22, and SW1 is turned on in advance while the operation lever 22a is moved, and then the fire extinguishing button (2) SW2 is turned on in the pressed position of Then, in the pressed position where SW2 is turned on, the valve body of the electromagnetic safety valve 23 is forcibly started, and in that state, the valve body is adsorbed and held in the valve open state by the electromagnet in the electromagnetic safety valve 23 .

When the electronic safety valve 23 is opened, gas flows into the heat control device 22 and flows out toward the burner 12 through the inside of the heat control device 22 . The outflow flow rate is increased or decreased by operating the thermal power control lever 21 .

The gas discharged from the thermal power control device 22 flows to the first opening/closing valve 24 . An orifice 25 is connected in parallel to the first on-off valve 24, and when the first on-off valve 24 is in the valve open state, the gas flows downstream without being tightened at all, but the first on-off valve When (24) is closed, a small amount of gas defined by the orifice (25) flows downstream. A second on-off valve 26 is installed downstream, and when the second on-off valve 26 is closed, gas is never supplied to the burner 12 . Further, the pot bottom sensor 13 is provided with a micro switch 13a. As described above, when a cooking utensil such as a frying pan FP is placed and the pot bottom sensor 13 is depressed, the micro switch 13a ) is turned on, and it can be detected that the cooking utensils are placed on the burner 12 .

Referring to FIG. 3 , a control unit 4 is installed in the gas stove device 1 , and the electronic safety valve 23 maintains the valve open and the first on/off valve 24 and the second on/off valve 26 . At the same time as the opening and closing of the igniter 15, the input of the on signal of the micro switch SW2 and the micro switch 13a, and the temperature detection signal by the pot bottom sensor 13 or the thermocouple 14 input is made.

With reference to FIG. 4, the control contents by the control part 4 are demonstrated. When performing the ignition operation, press the ignition button (2) in the case of normal cooking, and when the ignition is performed in a state where cooking utensils are not placed, the forced ignition switch (3) ( Press and operate the ignition button (2) in the state in which the roasted high-temperature stir-fry SW) is pressed (above, PS). In either case, since the control part 4 is not energized, the control part 4 cannot detect what kind of operation is made|formed by PS.

When the ignition button 2 is pressed, SW1 is turned on during the pressing operation, and power from the battery is supplied to the control unit 4 at that point. Then, the control unit 4 immediately checks whether the forced ignition switch 3 (roasted hot stir-fry SW) is in the on state (S1). This forced ignition switch (3) (roasted and roasted SW) is a non-lock switch that operates momentarily, and turns on only while pressing, and turns off when pressing is stopped. will come back In normal cooking, as described above, the forced ignition switch 3 (roasted and fried SW) is not turned on, so proceed to S2 and check whether the microswitch 13a (no-pot detection switch) is on. Check it. In addition, for example, even if the forced ignition switch 3 (roasted high-temperature SW) is continuously pressed, if the hand is released during the ignition operation, the ignition operation is performed without pressing the forced ignition switch 3 (roasted high-temperature stir-fry SW). Since it is performed in the same way as the normal ignition operation, the process proceeds to S2. Here, if the microswitch 13a (no-pot detection switch) is off, the ignition operation is performed without placing the cooking utensils, so the burner 12 is not ignited and ignition is prohibited (S3). . This corresponds to the ignition prohibition means.

On the other hand, if the micro switch 13a (no-pot detection switch) is on, since the cooking utensils are placed on the burner 12, the first on-off valve 24 is opened to increase the heat, and the second on-off valve at the same time By opening (26), the igniter 15 is further operated to ignite the burner 12 (S4). When ignition of the burner 12 is confirmed by the detection signal from the thermocouple 14 (S5), the normal thermal power control (ND) is shifted. In this normal thermal power control (ND), the microswitch 13a (no-pot detection switch) is always monitored (S6), and when the cookware is lifted and the microswitch 13a (no-pot detection switch) is turned off, , out of the normal thermal power control (ND), open the first on/off valve 24, and take out the gas flow through the orifice 25 to reduce the thermal power (S8). In addition, in normal thermal power control (ND), the forced ignition switch 3 (roasted hot SW) is always monitored, and if the forced ignition switch 3 (roasted hot SW) is continuously pressed for 3 seconds, It shifts to high-temperature thermal power control (HD) which will be described later (S7).

Then, when the cooking utensil is lifted by normal thermal power control (ND) and the state continues for 60 seconds (S9), the burner 12 is extinguished as a pot no error (S12), but the cooking utensil is again within 60 seconds When placed, the first on/off valve 24 is opened to return the thermal power to a strong fire, and the normal thermal power control (ND) is returned (S10, S11).

Returning to the beginning of this flow, if the forced ignition switch 3 (roasted high-temperature stir-fry SW) is on at the time when power is supplied to the control unit 4, proceed to S100 and the first on-off valve 24 in the open state ignition is carried out. And, in this state, the oil overheat prevention function is still set to the normal mode. This oil overheat prevention function is a function of monitoring the pot bottom temperature of cooking utensils with the pot bottom sensor 13, and controlling the heat by opening and closing the first on/off valve 24 so that the pot bottom temperature does not exceed the overheating temperature. .

Subsequently, if the forced ignition switch 3 (roasting high-temperature stir-fry SW) is on for more than 3 seconds (S101, S102), raising the temperature controlled by the oil overheat prevention function, and performing high-temperature stir-frying It is switched to a possible high-temperature mode (S103). Then, when the microswitch 13a (no-pot detection switch) is turned off, the function of reducing the heat to low heat is released to maintain the high heat as it is (S104). Although not shown in this flow, such high-temperature thermal power control (HD) automatically extinguishes the burner 12 if it continues for 30 minutes. In addition, while shifting to the high-temperature thermal power control (HD), the LED 31 is turned on or flashed to notify that the high-temperature thermal power control (HD) state is entered.

When the forced ignition switch 3 (roasted high-temperature stir-fry SW) is pressed in the high-temperature heat control (HD) state (S105), the high-temperature heat control (HD) escapes and the oil overheat prevention function returns to the normal mode. After that (S106), the process shifts to the above-described normal thermal power control (ND).

In addition, in S101, if the forced ignition switch 3 (roasted high-temperature stir-fry SW) is turned off before 3 seconds have elapsed, ignition is confirmed in S5, and then the normal heat control (ND) is performed.

Incidentally, in this case, instead of proceeding to S5, it may proceed to S3 only at the time of the ignition operation and control so that ignition is prohibited.

By the way, in the flow shown in FIG. 4, before confirming that the forced ignition switch 3 (roasted high-temperature stir-fry SW) is continuously pressed for 3 seconds in S102, the burner 12 was ignited in S100 beforehand, but this The timing may be changed to ignite the burner 12 after confirming that the forced ignition switch 3 (roasted hot stir-fry SW) is continuously pressed for 3 seconds in S102 without igniting the ignition.

In addition, this invention is not limited to an above-mentioned form, You may make various changes within the range which does not deviate from the summary of this invention.
