Description

Gas control apparatus

The present invention relates to a gas control device for controlling the supply of fuel gas, for example, to a gas burner installed in a gas stove.

These gas control devices each have a fire extinguishing button for igniting and extinguishing the gas burner and a fire control dial for adjusting the amount of fuel gas supplied to the gas burner in order to ignite the gas burner so as to make the fire power of the gas burner a predetermined fire power. It is known that the thermal power control dial is rotated to a predetermined position by moving the front and rear direction of the ignition button (Patent Document 1-Japanese Patent No. 2742356 (for example, the contents described in the claims)).

In this case, the ignition button is formed in a cylindrical shape, and is freely moved in the front-back direction, for example, on the operation panel on the front of the stove. Then, when the fire button is pressed in the valve closing position for closing the gas passage, the fire button is moved to the ignition position, the gas passage is opened, and the ignition means of the gas burner is operated. When the gas burner is confirmed to be ignited and the pressure of the ignition button is released, the ignition button protrudes from the operation panel and moves to the valve open position.

The thermal control of the gas burner in the valve open position is performed by a ring-shaped thermal control dial provided around the ignition button. The thermal control dial is interlocked with a gas flow rate adjusting means for changing the opening area of the gas passage installed in the gas passage to control the gas flow rate of the fuel gas to the gas burner. When the combustion of the gas burner is stopped, when the ignition button located at the valve open position is pressed to move to the valve closed position, the gas passage is closed to extinguish the gas burner. In this case, a reset means for forcibly rotating the thermal control dial to the reinforcement position is provided according to the pressurization operation of the ignition button. It is not possible to rotate the thermal power control dial in the valve closing position of the ignition button by the reset means.

Therefore, the ignition button is configured to move from the valve closing position protruding from the operation panel to the ignition position through the valve opening position by the pressurization operation during the ignition operation, and in conjunction with the pressurization operation during the ignition operation of the ignition operation. It is contemplated to provide a mechanism for forcibly rotating the thermal control dial so that the amount of combustion gas supplied to the gas burner is a predetermined amount. By the way, when this forced rotation is performed from the closed button position to the valve open position, the fire-extinguishing button for rotating the fire control dial to a predetermined position between the valve closed position and the valve open position is performed. It is necessary to secure the movement distance, and as a result, the movement distance in the front-back direction of the ignition button of the ignition operation becomes long, resulting in a problem that the use becomes inconvenient.

Herein, in view of the above, the present invention has a short and easy moving distance in the front and rear directions of the ignition button even when the fire control dial is forcibly rotated by the pressurization operation of the ignition button during ignition operation. An object of the present invention is to provide a control device.

In order to solve the above problems, the gas control device of the present invention is provided with a ignition button which is free to move in the front and rear directions, and closes the valve opening position and the gas passage to keep the gas passage leading to the gas burner at the position in the front and rear directions. The valve closing position and the ignition position for operating the ignition means of the gas burner are provided, and the ring-shaped fire control dial is freely rotated to adjust the amount of fuel gas supplied to the gas burner around the ignition button. In the installed gas control device, the ignition button is configured to move from the valve closing position protruding by the pressurization operation during the ignition operation to the ignition position via the valve opening position, and during the ignition operation of the ignition operation. When forcibly rotating the thermal control dial so that the combustion gas supply amount of the gas burner is linked to the pressurized operation. The key is provided with a forced rotation means, and the forced rotation of the fire control dial by the forced rotation means is characterized in that the ignition button proceeds from the valve open position to the ignition position.

According to the present invention, when the ignition button is pressed in the valve closing position for ignition operation, the gas passage is opened and fuel gas flows through the gas burner. When the ignition button reaches the valve opening position, the rotation of the thermal control dial is started by the forced rotation means, and when the ignition position is reached, the ignition operation of the gas burner is performed. In this case, when the ignition position is reached, the rotation of the thermal power control dial to the predetermined position has already been completed. When the ignition of the gas burner is confirmed and the pressurization of the ignition button is released, the ignition button is returned to the front side to reach the valve opening position. When the thermal control dial is rotated in the valve open position, the gas flow rate of the combustion gas supplied to the gas burner may be increased or decreased, thereby controlling the thermal power of the gas burner.

Here, the gas passage is generally provided with an electronic safety valve, and opening the electronic safety valve does not require setting a long distance of the ignition button between the valve open position and the ignition position when the ignition button is pressurized. have. In this case, in the present invention, since the moving distance of the ignition button is long between the valve opening position and the ignition position for forced rotation of the thermal control dial, the required valve closing position and the valve opening position are short. The operation distance is good and easy to use because the movement distance of the ignition button can be shortened rather than adding the movement distance for forced rotation of the fire control dial to the movement distance of the ignition button between positions. In addition, since the operation of returning from the ignition position to the valve opening position is used for disengagement of the forced rotation means, there is no need to install a mechanism that does not interfere with the thermal control dial at the valve opening position. There is no need to increase.

Then, the forced rotation means is composed of a projection piece provided on the pressure rod for moving the inside of the thermal power control dial in the front and rear direction by pressing the ignition button, and a cam groove provided on the inner circumferential surface of the thermal power control dial, As the ignition button moves to the ignition position, the projection piece engages with the cam groove.When the ignition button is released and the ignition button is released from the ignition position to the valve open position, the projection piece does not engage with the cam groove. In this case, there is no need to increase the number of parts, the operability of the thermal power control dial in the valve open position is not degraded, and it does not adversely affect the cooking operation of the cooker.

In addition, when the thermal power control dial is rotated in the valve open position, the projection piece abuts on the inner side of the thermal power control dial in which the cam groove is formed, and an iron part is provided to limit the rotation range of the thermal power control dial. There is no need to install a stopper for limiting the rotation range of the thermal control dial, and the number of parts is reduced, thereby reducing the cost.

When the thermal power control dial is rotated to a predetermined position beyond the rotation range at the valve closing position, the front surface of the convex part faces the projection piece, and locks to prevent the pressure operation of the ignition button. You may also install a location.

It is. Front panels 24, which are operating panels, are provided at both ends of the front surface of the stove body 21. In addition, the grill body 21 is provided with a grill 25 positioned between both front panels 24 and provided with a ceramic plate burner (not shown). The supply of fuel gas to the three gas burners 23 and the ceramic plate type burners is controlled by the gas control device 1 of the present invention.

Referring to FIG. 2, the gas control device 1 has a valve casing composed of two parts 11a and 11b connected up and down. A first inner passage 12a extending along the longitudinal direction of the valve casing is provided in the first portion 11a of the valve casing positioned below, and the gas inflow portion 13 communicating with the first inner passage 12a. Is established. An electromagnetic safety valve 3 is provided in the first inner passage 12a located downstream of the gas inflow portion 13. The electromagnetic safety valve 3 has a magnet case 31, which includes, for example, an electromagnet which is intended to be subjected to a signal of a control unit (not shown) installed in the stove body 21. The adsorption piece adsorb | sucked to this is accommodated.

The first valve body 32 protruding from the magnet case 31 toward the downstream side of the first inner passage 12a is connected to the suction piece. When the solenoid safety valve 3 is in the closed state, the first valve body 32 is elastically supported by the repulsive force of the spring 33 built up between the first valve body 32 and the magnet case 31. Then, it is seated on the valve base of the valve base member 34 provided in the first inner passage 12a through the actual material 34a. The operation of opening the solenoid safety valve 3 is inserted into the first inner passage 12a through the actual material 41 and is freely movable in the front-rear direction along the long axis direction of the first inner passage 12a. ) Is performed. The operation rod 4 is provided with a second valve body 42, and the second valve body 42 forms a one-way valve together with the valve base 43 provided in the first inner passage 12a. In the valve-closed state of the original valve, the second valve body 42 is attached to the valve base 43 by a spring 44 which is built up between the second valve body 42 and the valve base member 34. .

The movement of the training rod 4 in the front-rear direction is performed by the pressing operation of the ignition button 5 provided on the front panel 24. The ignition button 5 is formed in a cylindrical shape, and a pressure rod 51 for pressurizing the operation rod 4 in accordance with the movement of the ignition button 5 is connected to a cross section of the first inner passage 12a side. It is. A guide portion 51a is connected to the lower side of the pressure rod 51, and one end of the guide portion 51a is connected to a hard cam mechanism 52 provided below the first portion 11a.

As shown in Figs. 2 to 4, the ignition button 5 is protruded from the front panel 24 together with the thermal control dial to be described later, and the valve closing position for closing the first inner passage 12a (see Fig. 2). In order to perform the ignition operation in the direction of the stove body 21 toward the back side (the right side in Fig. 2) to the ignition button 5 to operate the pressure control button (4) through the pressure rod 51 After pressurizing to the rear side and opening the one-valve, it presses the valve body 32 to the suction piece side and moves to the ignition position which the discharge unit (not shown) which is an ignition means operates (refer FIG. 3). When the pressure of the ignition button 5 is released at the ignition position, the hard cam mechanism 52 is guided and moved to the front side (the left side in FIG. 3) in the direction toward the outside of the stove body 21 to maintain the one-valve opening. The valve opening position is reached with the first inner passage 12a open (see FIG. 4). Pressing the ignition button 5 in the valve open position to perform the ignition operation resets the hard cam mechanism 52 to return to the ignition position (states shown in Figs. 1 and 2).

The gas outlet 14 is provided in the 1st part 11a located upstream of a one-valve, and this gas outlet 14 is provided of the substantially L-shaped 2nd inner passage 12B provided in the 2nd part 11b. Consistent with one end, each of the first and second inner passages 12a and 12b constitute a gas passage. Four first, second, third and fourth communication paths 15a, 15b, 15c and 15d are spaced apart from each other on the outer circumferential surface of the second portion 11b at predetermined intervals. The gas outlet 16 and the second inner passage 12b connected to the upper portion of the second portion 11b communicate with each other through the communicating passages 15a, 15b, 15c, and 15d. The fuel gas flowing out of the gas outlet 16 is supplied to a gas nozzle (not shown) for injecting fuel gas into each of the mixing tubes of the gas burners 23 and the ceramic plate burners. In this case, in order to adjust the gas supply amount of the fuel gas to the gas nozzle, the flow control valve 6 is provided in the second inner passage 12b.

2 and 5, the flow regulating valve 6 has a cylindrical rotor 61 rotatably inserted into the second inner passage 12b. Four circumferential first, second, third, and fourth long grooves 62a, 62b, 62c, and 62d are formed on the outer circumferential surface of the rotating body 61, respectively. Are formed to correspond to the communication paths 15a, 15b, 15c, and 15d, respectively. In this case, the width dimensions of each of the long grooves 62a, 62b, 62c, and 62d coincide with the hole diameters of the communication paths 15a, 15b, 15c, and 15d, respectively, and are formed so as not to overlap in the circumferential direction. In this case, four orifice holes 63a, 63b, 63c, and 63d for controlling the gas flow rate of the fuel gas flowing through the communication paths 15a, 15b, 15c, and 15d to the gas outlet 16 to a predetermined amount. The orifice member 63, which has been formed in accordance with the communication paths 15a, 15b, 15c, and 15d, is mounted on the upper surface of the second portion 11b. Then, the gas flow rate of the fuel gas flowing to the gas outlet portion 16 by rotating the rotor 61 to match the long grooves 62a, 62b, 62c, and 62d with the communication paths 15a, 15b, 15c, and 15d, respectively. Let this be adjusted. Adjustment of the rotation angle of the rotating body 61 is performed by the ring-shaped thermal power control dial 7 provided around the ignition button 5.

By the way, the fire button 5 and the fire control dial 7 are installed on the front panel 24 of the stove body 21, but the fire button 5 protrudes from the fire control dial 7 at the valve open position. As a result, for example, boiled broth generated during cooking and debris contaminated by grilling 25 etc. are attached. Moreover, when it boils over at the time of cooking, the broth flows into the ignition button 5, and may penetrate into the stove 2 through this ignition button 5, and may adversely affect an electric substrate and a switch.

2 and 6, in the present embodiment, the ignition button 5 and the fire control dial 7 are disposed so that the outer circumferential surface of the fire ignition button 5 is concealed in the fire control dial 7 and the front panel 24. The cross section on the front side of the front side is substantially coincided with the space, and a space S is provided over the entire edge between the outer circumferential surface of the ignition button 5 and the inner circumferential surface of the thermal power control dial 7. Then, in the valve closing position, the ignition button 5 and the thermal power control dial 7 are integrally projected toward the front side from the front panel 24, and the ignition button 5 is moved to the valve opening position through the pressurizing operation. In this case, the fire control dial 7 was moved to the rear side. In this case, the thermal power control dial 7 protrudes from the front panel 24 only a length through which the cooker can control the thermal power of the gas burner 23 by operating the thermal power control dial 7.

As a result, the fire ignition button 5 and the fire control dial 7 are press-fitted to the rear side of the valve closing position and the outer circumferential surface of the fire ignition button 5 is always concealed by the fire control dial 7. Even when boiling occurs during cooking, the broth is hard to approach the fire control dial (7), and even if the broth is stuck on the fire control dial (7), the broth will fall downward along the periphery and the outer peripheral surface of the fire button (5) The broth does not break in. Therefore, the broth is prevented from entering the microwave 2 along the ignition button 5. In addition, since the space (S) is provided, the residue is stuck between the ignition button (5) and the thermal control dial (7) to smoothly rotate the thermal control dial (7) by pressurizing the ignition button (5). The movement can be prevented from being inhibited.

The thermal power control dial 7 is provided with the handle part 71 which is free to rotate to move simultaneously with the front-back direction of the ignition button 5, and the dial member 72 which rotates the rotating body 61. As shown in FIG. The end of the dial member 72 on the first inner passage 11a side has teeth formed with a predetermined pinch, and the toothed portion 72a is fitted to one end of the rotating body 61 which protrudes from the second portion 11b. It is engaged with the gear G which was put together. Thereby, the other end of the dial member 72 is provided in two places with the concave part 72b which protruded radially outer side and mutually opposed.

The handle member 71 concealing the outer circumferential surface of the ignition button 5 is made of a transparent resin material, and a protruding piece 71a extending toward the first inner passage 11a side at an end portion of the first inner passage 11a side. It is installed in two places facing each other. And the handle member 71 and the reflecting member 73 which correspond substantially to the internal shape of the dial member 71 which are engaged so that each protrusion piece 71a slides freely in each recess part 72b are attached, have. On the outer surface of the reflective member 73, a reflective layer is formed by coating aluminum. The reflecting member 73 is further provided with a shading portion 73a which abuts against an end portion 5a formed on the outer circumferential surface of the ignition button 5 and an end portion 71b formed on the inner circumferential surface of the handle member 71. The reflection member 73 is elastically supported to the front side by the spring 74 arranged between the shade portion 73a and the dial portion 72.

Thereby, when the handle member 71 is pressed against the ignition button 5 by the repulsive force of the spring 74, and pressurizes the ignition button 5, the handle member 71 moves to the rear side by this, and a valve opening opens. In the position, when the handle member 71 is rotated, the dial member 72 is rotated through the recessed portion 72b engaged with the protruding piece 71a. On the other hand, in the valve closing position of the ignition button (5) it is possible to move alone in the direction in which the thermal power control dial 7 exposes the outer circumferential surface of the ignition button (5). In this case, when the handle portion 71 is moved in the valve closing position, the outer circumferential surface of the ignition button 5 is exposed and the debris attached thereto can be cleaned. In addition, since the ignition button 5 does not move even when the power control dial 7 is gripped and pressed, the forced rotation means described later is not damaged. In addition, the reflection member 73 is concealed by the reflection member 73 even if debris or the like adheres to the outer circumferential surface of the ignition button 5.

Referring to FIG. 7, inside the front panel 24, a light source E such as an LED for irradiating light toward the reflective member 73 from above the transparent handle member 71 is provided, and the ignition button 5 is provided. The handle member 71 is radiated by irradiating the light of the light source at the valve open position of the). Thereby, the operation | movement state of the microwave oven 2 can be visually confirmed. In this case, when the edge of the front side of the said thermal power control dial 7 is made into the chamfer C, this chamfer C is irradiated to the dial member 71 by the light of the light source E. In FIG. ) To shine in a ring shape. Moreover, the iron part 73b extended in the long axis direction is formed in the surface of the reflecting member 73 (refer FIG. 6), and this iron part 73b is the accommodating part of the long axis direction provided in the handle part 71. FIG. It is housed in 71c and constitutes an index portion indicating the thermal power of the gas burner 23 by matching the thermal position of the gas burner displayed on the front panel 24 with the convex portion 73b. In addition, since the indicator part does not shine even when light from the light source E is irradiated, the indicator part has an effect that stands out with respect to the shining surroundings, and the cook is likely to recognize the coincidence of the fire position and the indicator part.

8 to 12, a cam groove 72c is formed on the inner circumferential surface of the rear side of the dial member 72, and a cam groove on the outer circumferential surface of the pressure rod 51 for moving the inside of the dial member 72 in the front-rear direction. Two projection pieces 51b mating with 72c are provided (see Fig. 6), and the cam groove 72c and the projection pieces 51b constitute a forced rotation means. In this case, the height of the wall surface of the cam groove 72c is formed so that it may become low from one side to the other according to the pressurization operation of the ignition button 5. When the gas burner 23 reaches the valve opening position by pressurizing the ignition button 5 at the valve closing position to ignite the gas burner 23, the projection piece 51b is engaged with the cam groove 72c. The projection piece 51b is driven to rotate the dial member 72 having the cam groove 72c as the driven shaft, and the fuel gas at a flow rate that ensures ignition when the ignition button 5 reaches the ignition position is gas. It rotates to the position supplied to the burner 23. In this embodiment, by the forced rotation means 51b and the cam groove 72c, the thermal power control dial 7 is forcibly rotated to the center position by pressurizing the ignition button 5.

In this case, since the thermal power control dial 7 is rotated using the pressurization operation of the ignition button 5, for example, of the spring 17 built up between the pressure rod 51 and the first portion 11a. It is not necessary to increase the repulsive force, and the structure of the gas control device 1 can be simplified. In addition, it is useful for forcibly rotating the thermal control dial 7 between the valve opening position and the ignition position, in which the ignition button 5 is set to have a long moving distance to open the electronic safety valve 3. Of the fire-extinguishing button 5 by adding a distance for forced rotation of the fire control dial 7 to the moving distance of the fire-extinguishing button 5 between the valve closing position and the valve-opening position. The movement distance in the front and rear direction can be shortened, so the operation feeling is good and the use is easy

In the ignition position, the gas burner 23 is ignited by operating the discharge unit. Then, when the pressurization of the ignition button 5 is released, it is guided to the hard cam mechanism 52, and is slightly returned by the pressing force of the spring 17, and the ignition button 5 reaches the valve opening position. In the valve open position, the engagement of the projection piece 51b and the cam groove 72c is released so that the dial member 72 is free to rotate clockwise or counterclockwise. In this case, when the thermal power control dial 7 is rotated in the clockwise direction, the gas flow rate is reduced, and when the counterclockwise rotation is performed, the rotor 61 is rotated so that the gas flow rate is increased. As a result, the operability of the thermal power control dial 7 in the valve opening position is not deteriorated and does not adversely affect the cooking operation of the cooker. In addition, since the engagement of the projection piece 51b and the cam groove 72c is released by the return of the ignition button 5 when the pressurization of the ignition button 5 is released, a forced rotation is performed at the valve opening position. Since the mechanism 51b does not need to be designed separately so that the means 51b does not interfere with the cam groove 72c of the thermal power control dial 7, there is no need to increase the number of parts.

In order to limit the rotation range of the thermal power control dial 7, two convex portions 72d are formed which face each other at the position where the cam groove 72c of the dial member 72 is formed. When the thermal power control dial 7 is rotated and rotated counterclockwise until each projection piece 51b abuts on the convex portion 72d, the second, third, and fourth long grooves ( 62b, 62c, and 62d correspond to the second, third, and fourth communication paths 15b, 15c, and 15d, respectively, so that the rotor 61 is disposed so that the amount of gas to the gas outlet 16 is increased. have. On the other hand, when the projection pieces 51b are rotated clockwise until the projections 51b abut on the convex portion 72d, the first long groove 62a coincides only with the first communication path 15a. The amount of gas to 16 is minimized. As a result, in the valve opening position, the thermal power control dial 7 minimizes the gas flow rate to the gas outlet 16 and minimizes the fire power of the gas burner 23 to the maximum. The rotation is free only within the thermal power control range between the thermal power of the gas burner 23 and the strong thermal power. Thereby, there is no need to separately install a stopper or the like for limiting the rotation range of the thermal power control dial 7, and the number of parts is reduced, thereby reducing the cost.

As shown in FIG. 13, in the valve closing position of the ignition button 5, the projection piece 51b is located in the front side rather than the position which formed the cam groove 72c of the dial member 72. As shown in FIG. In this case, in the valve closing position, the thermal power control dial 7 is rotated counterclockwise over the thermal power control range, and in this position, the projection piece 51b faces the convex portion 72d. As a result, even when the ignition button 5 is pressed, the projection piece 51b abuts against the front panel 24 front side surface of the convex portion 72b and moves from the valve closing position to the ignition position. The lock position is formed so that the fire extinguishing button 5 is not moved, which is a child lock. In this case, when the protrusion part E is provided in the outer peripheral surface of the dial member 72 (refer FIG. 8), and this protrusion part E contact | connects the stopper (not shown) provided in the 1st part 11a, The lock position is reached.

6 and 14, the first, second, and third recessed portions 72e, 72f, 72g are disposed on the inner circumferential surface of the front side of the dial member 72 at predetermined intervals on the same circumferential direction. ) Is formed. A radial hole 5b is formed at the rear end of the ignition button 5, and in this hole 5b a cylindrical creek member C is directed toward the inner circumferential surface of the dial member 72 to the spring C1. It is stored in a supported state. When the thermal power control dial 7 is rotated at the valve open position to reach a predetermined position, the creek member 52 is fitted to the recesses 72e, 72f, and 72g to generate a creek.

Next, the operation of the gas control device 1 of the present invention will be described. When pressing the ignition button 5 in the valve closing position shown in FIG. 2, the operation rod 4 is pushed to the rear side through the pressure rod 51 to open the one-way valve, and the valve shown in FIG. When the opening position is reached, the projection piece 51b and the cam groove 72c are engaged with each other, and the thermal power control dial 7 is neutralized before reaching the ignition position for pressing the valve body 32 toward the suction piece side. Rotate to the fire position. In this case, the rotating body 61 is rotated through the gear G, and in this position, the first, second, and third long grooves 62a, 62b, 62c are formed in the first, second, and third directions. The fuel gas of the gas flow volume which matches each communication path 15a, 15b, 15c and puts the thermal power of the gas burner 23 into the gas outflow part 16 (refer FIG. 5). In addition, the creek member C is fitted to the second recessed portion 72f (see FIG. 14).

When the ignition position is reached, the ignition operation of the gas burner 23 is performed by the discharge unit. When the flame detection element (not shown) provided near the gas burner 23 detects the flame of the gas burner 23, the solenoid valve 3 is activated by a signal from the control unit to maintain the valve open. do. When confirming that the gas burner 23 has ignited and releasing the pressurization of the ignition button 5, the ignition button 5 is guided to the hard cam mechanism 52 to reach the valve opening position shown in FIG.

When the creek member C is fitted to the third recessed portion 72g by rotating the gas burner 23 in a counterclockwise direction at a neutralized position to make the firepower strong, the convex portion 72d. Each projection piece 51b abuts. In this case, the second, third, and fourth long grooves 62b, 62c, and 62d correspond to the second, third, and fourth communication paths 15b, 15c, and 15d, respectively, so that the gas burner ( The fuel gas of the gas flow rate which uses the thermal power of 23) flows into the gas outflow part 16 (refer FIG. 15).

On the other hand, in order to reduce the thermal power of the gas burner 23 in the neutralization, when the thermal power control dial 7 is rotated clockwise to fit the creek member C to the first recessed portion 72e, the first and the second Each of the long grooves 62a and 62b of the coincides with the first and second communication paths 15a and 15b, respectively, so that the fuel gas having a gas flow rate that weakens the thermal power of the gas burner 23 is the gas outlet 16. (See Fig. 16). Then, when the thermal power control dial 7 is rotated clockwise until each projection piece 51b abuts on the convex portion 72d, the first chapter 62a coincides only with the first communication path 15a. Then, the fuel gas of the minimum gas flow rate which makes the thermal power of the gas burner 23 weak is flowing to the gas outlet part 16 (refer FIG. 17).

When the gas burner 23 is extinguished, the hard cam mechanism 52 is reset by pressing the fire button 5 toward the rear side from the valve open position, and the fire button 5 is the spring 17. Receives the repulsive force of and reverses to the valve closed position shown in FIG. In this case, the operation rod 4 in which the pressure of the pressure rod 51 is released is moved to the front side under the repulsive force of the spring 34 to close the one valve. When the original valve is closed, the supply of fuel gas to the gas burner 23 is stopped and extinguished. When the control unit recognizes that the flame has been extinguished by the flame detection element, the electronic safety valve 3 is closed.

Incidentally, although the reflective layer is formed in the reflective member 73 in the present embodiment, the present invention is not limited thereto, and a reflective layer may be formed inside the dial member 72, for example. In addition, although the case where the ignition is performed in the neutralization position has been described in the present embodiment, the cam groove may be formed so that the ignition operation is possible, for example, without being limited to this. In the present embodiment, the case where the ignition button 5 and the gas adjusting dial 7 are provided on the front panel 24 of the gas stove 2 has been described. However, other gas cooking appliances such as an oven and a grill are described. The gas control apparatus of the present invention having an ignition button and a fire control dial may be used. For example, the gas stove having the operation panel mounted on the upper plate covering the stove body may have a fire button and a fire control dial. A gas control device may be applied.

As described above, the gas control apparatus of the present invention shortens the child distance in the front and rear directions of the ignition button even if the fire control dial is forcibly rotated by the pressurization operation of the ignition button during the ignition operation. The effect becomes easy.
