Description

Gas control apparatus

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gas control device, and more particularly, to a gas control device installed in a gas appliance such as a gas furnace to control a fuel gas supply to a gas burner.

A gas control device of this kind is shown, for example, in Japanese Patent No. 2742356. It has, for example, a fire-extinguishing button installed on the front panel of the gas stove and freely moving in the front-rear direction, and the gas passage leading to the gas burner is located at the other three positions in the front-back direction of the fire-extinguishing button. The open position to hold open, the ignition position to operate the ignition means of a gas burner, and the closed position to close a gas passage are provided.

Pressing the ignition button in the closed position moves the ignition button to the ignition position to open the gas passage and operate the ignition means of the gas burner. When the gas burner is confirmed to be ignited and the pressure of the ignition button is released, the ignition button is protruded and moved to the opening position.

In the open position, the gas power control is performed by a ring-shaped power control dial provided around the ignition button. The thermal power control dial is interlocked with the gas flow rate adjusting means which is installed in the gas passage to change the opening area of 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, the gas passage is closed and the gas burner is extinguished by pushing the ignition button at the opening position to the closed position.

Here, for ignition operation of the gas burner, it is preferable to supply the fuel gas to the mixing pipe of the gas burner so that the ignition of the fuel gas is ensured, for example, so that the heat power of the gas burner is strong or heavy.

To this end, in the above, when extinguishing the gas burner, the reset is performed by forcibly rotating the fire control dial to a position where the fire power of the gas burner becomes strong, in conjunction with the pressurization operation of the ignition button. (reset) means are provided.

Recently, in consideration of safety, a so-called child lock mechanism is installed on the ignition button so that the gas burner does not operate even if a child or the like accidentally touches the ignition button, and the ignition button is ignited, for example, at the closed position. Many restrict movement to position and prevent the ignition means from working.

Here, when the child lock mechanism is provided in the above-described manner, since the reset means is provided, the fire control dial cannot be rotated at the closed position of the ignition button.

Therefore, it is desirable to separately install the child lock control unit so that the ignition means do not operate at the closed position, but the installation of the separate control unit not only deteriorates the operability during the ignition operation of the gas burner but also increases the number of parts, Causes an increase.

The present invention has been made to solve this problem, it is an object of the present invention to provide a gas control device capable of child lock in the closed position without installing a separate child lock control unit.

16: gas outlet portion 5: ignition button

7: Fire control dial

The gas control apparatus of the present invention for achieving the above object is provided with a ignition button that is free to move back and forth between the opening position to maintain the gas passage leading to the gas burner and the closed position closing the gas passage. And a fire extinguishing power for supplying a minimum gas flow rate to the gas burner to weaken the fire power, and a reinforcing power for supplying the maximum gas flow rate to the gas burner at the opening position of the fire extinguishing button around the fire extinguishing button. In a gas control apparatus provided with a ring-shaped thermal power control dial which is free to rotate in at least the thermal power control range therebetween, the thermal power control dial is free to rotate beyond the thermal power control range at the closed position of the ignition button. If the fire control dial is rotated beyond the fire control range, the ignition means of the gas burner will not operate. Characterized in that a value.

According to the present invention, when the ignition button is moved to one side by operating the ignition button in the closed position, the gas passage is opened and the fuel gas flows into the gas burner to operate the ignition means. When the ignition operation is terminated by the ignition means and the operation of the ignition button is canceled, the ignition button reaches the opening position. In this case, the gas passage is kept open.

When the thermal power control dial is rotated within the thermal power control range at the opening position, the gas flow rate of the fuel gas supplied to the gas burner may be increased or decreased, thereby controlling the thermal power. Then, by operating the ignition button to extinguish the gas burner and moving from the open position to the closed position, the gas passage is closed to stop the supply of fuel gas to the gas burner.

In the closed position, the thermal control dial can be rotated beyond the thermal control range. Rotating the fire control dial to the lock position results in a so-called child lock and the ignition means does not work.

Here, in the case of a child lock, an ignition position for operating the ignition means of the gas burner in the middle of the movement path, for example, from the closed position to the open position, and the ignition position at the closed position of the fire button You may want to limit movement to a location.

In the ignition operation of the gas burner, the ignition of the fuel gas is surely performed, for example, the fuel gas may be supplied so that the fire power of the gas burner is strong or heavy. In this case, when the ignition operation of the ignition button is carried out, a forced rotation means for forcibly rotating the thermal control dial to provide a predetermined thermal power of the gas burner may be provided.

And, the ignition operation is to press the operation button is moved from the closed position to the ignition position by the pressurization operation of the ignition button, the pressing force during the pressurization operation can be used for the rotation of the thermal control dial by the forced rotation means, For example, the structure of the device can be simplified.

In addition, the rotation range of the thermal control dial is limited to the thermal power control range at the opening position of the ignition button so that the thermal power control dial does not rotate beyond the thermal control range.

On the other hand, if the soup overflows from cooking utensils such as a pot during cooking, for example, if the gas burner can be stopped quickly by pressing the ignition button to stop the combustion of the gas burner. The method of use can be improved.

In this case, the fire control dial at the opening position of the fire-extinguishing button is free to rotate to the fire power side beyond the fire control range, and if the fire control dial is rotated beyond the fire-extinguishing position, it is forcibly moved to the closing position. It is good to install a transportation means.

In addition, the display means for recognizing that the ignition means does not operate when the fire control dial is in the lock position so that the cooker can easily recognize that the child lock has been made.

With reference to FIG. 1, the gas control apparatus 1 which concerns on 1st Embodiment is assembled to the gas furnace 2, for example. In this case, the gas cooker 2 has a box-shaped cooker body 21 and two gas burners 23a which face the two openings provided in the top plate 22 covering the upper surface of the cooker body 21. 23b is provided.

The grill furnace body 21 is further provided with a grill 25 located between the front panels 24 provided at both ends of the front face and provided with a ceramic plate burner (not shown). The gas control device 1 of the present invention controls the supply of fuel gas to the two gas burners 23a and 23b and the ceramic plate burner.

Referring to FIG. 2, the gas control device 1 has a valve casing composed of two parts 11a and 11b which are connected to each other in the vertical direction. The first inlet portion 11a of the valve casing positioned below is provided with a first inner passage 12a extending along the longitudinal direction of the valve casing, and a gas inflow portion 13 communicating with the first inner passage 12a. Opened.

The solenoid valve 3 is provided in the 1st inner passage 12a located downstream of the gas inflow part 13. As shown in FIG. The solenoid valve 3 has a magnet case 31 which is excited on the magnet case 3 based on a signal from a control unit (not shown) installed in the main body 21, for example. An electromagnet and an adsorption plate adsorbed to it are housed.

The adsorption plate is connected with a first valve body 32 protruding from the magnet case 31 toward the downstream side of the first inner passage 12a. In the closed state of the solenoid valve 3, the 1st valve body 32 is sealed by the repulsive force of the spring 33 built up between this 1st valve body 32 and the magnet case 31. It is seated on the valve base 43 of the valve base member 34 provided in the first inner passage 12a via 34a).

The opening and closing operation of the solenoid valve 3 is inserted into the first inner passage 12a through the actual material 41 and is performed by the operation rod 4 freely moving back and forth along the longitudinal direction of the first inner passage 12a. All.

Moreover, the 2nd valve body 42 is provided in the operation rod 4, and the 2nd valve body 42 comprises a far side with the valve base 43 provided in the 1st internal passage 12a. do. In the closed state of a far side, the 2nd valve body 42 is seated on the valve base 43 by the spring 44 extended between this 2nd valve body 42 and the valve base member 34. As shown in FIG.

The movement of the training rod 4 in the front-rear direction is performed by pressing operation of the ignition button 5 provided so as to protrude from the front panel 24 (see FIG. 1). The ignition button 5 is formed in a cylindrical shape, and a pressure rod 5a for pressurizing the operation rod 4 according to the movement of the ignition button 5 is connected to the end surface of the first inner passage 12a. It is.

In addition, one end of the pressure rod 5a is connected to the heart cam mechanism 5b provided below the first portion 11a. In this case, in order to perform ignition operation in the closed position (state shown in FIG. 1) which closes the 1st internal passage 12a which protruded from the front end surface of the above-mentioned thermal power control dial, pressurization operation of the ignition button 5 is performed. On the other hand, after the operating rod 4 is opened by the pressurizing rod 5a to change the far side pressurized in the rear direction (right side in FIG. 2), the valve body 32 can be pressurized to the suction piece side, and at the same time, the discharge unit serving as the ignition means. Move to ignition position (not shown).

When the pressurization of the ignition button 5 is opened in the ignition position, it moves in the omnidirectional direction (left side of FIG. 2) guided by the heart cam mechanism 5b to maintain the original side and open the first inner passage 12a. The opening position of is reached. Pressing the ignition button 5 in the open position to perform the extinguishing operation resets the heart cam mechanism 5b to return to the extinguishing position.

In addition, a gas outlet 14 is provided in the first portion 11a located on the upstream side of the far side, and the gas outlet 14 is a substantially needle-shaped second inner passage 12b provided in the second portion 11b. Coincides with one end of the first and second internal passages 12a and 12b and constitutes a gas passage.

On the outer circumferential surface of the second portion 11b, four first, second, third, and fourth communication paths 15a, 15b, 15c, and 15d are spaced apart from each other at predetermined intervals. The gas outlet portion 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. In this case, the diameters of the communication paths 15a, 15b, 15c, and 15d are formed large in sequence in the forward direction.

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 23a and 23b and the ceramic plate burner. In this case, in order to adjust the gas amount of the fuel gas to the gas nozzle, the flow rate regulating valve 6 is provided in the 2nd internal passage 12b.

As shown in FIG. 2 and FIG. 3, the flow regulating valve 6 has a cylindrical rotating body 61 which is freely rotatable in the second inner passage 12b via the actual member 61a. On the outer circumferential surface of the rotating body 61, four circumferential first, second, three, and four long grooves 62a, 62b, 62c, and 62d are formed in the first, second, third, and fourth 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 correspond to the diameters of the communication paths 15a, 15b, 15c, and 15d, respectively, and are formed so as not to overlap in the circumferential direction. .

In the present embodiment, four orifice holes 63a for adjusting 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 in which 63b, 63c, 63d was formed is matched with each communication path 15a, 15b, 15c, 15d, and is attached to the outer peripheral surface of the 2nd part 11b.

Then, the rotating body 61 is rotated so that the respective long grooves 62a, 62b, 62c and 62d are appropriately matched with the communication paths 15a, 15b, 15c and 15d to the gas outlet 16. Adjust the gas flow rate of the fuel gas flowing into the furnace.

Adjustment of the rotation angle of the rotating body 61 is performed by the thermal power control dial 7 provided around the ignition button 5. As shown in Fig. 4, the thermal control dial 7 is constructed by attaching a ring-shaped cap 70b to a hollow cylindrical base 70a.

The end part of the 1st internal passage 11a side of the thermal power control dial 7 is provided with the tooth | gear at a predetermined pitch, and the tooth | gear part 71 is connected to the one end of the rotating body 61 which protruded from the 2nd part 11b. It meshes with the fitted tooth 72. As a result, the rotating body 61 is rotated in synchronization with the rotation operation of the thermal power control dial 7.

Here, in order to reliably ignite the fuel gas during the ignition operation of the gas burners 23a and 23b, for example, the fuel gas is supplied to the gas burner 23a so that the thermal power of the gas burners 23a and 23b is strong or heavy. It is good to supply to (23b).

In addition, in consideration of safety, it is recommended to install a so-called child lock mechanism so that the discharge unit does not operate even if a child or the like touches the ignition button 5 incorrectly. It leads to a cost increase.

2 to 6, in the present embodiment, the cam groove 73 is formed on the inner circumferential surface of the front direction of the thermal power control dial protruding from the front panel 24 and the inside of the hollow thermal power control dial 7 is moved forward and backward. The first projection piece 51 corresponding to the cam groove 73 is installed on the outer circumferential surface of the ignition button 5 moving to constitute a forced rotation means. In this case, the first protruding piece 51 is provided in the radial hole 52 provided in the outer peripheral surface of the ignition button in the state which has the repulsive force by the spring 53 toward radially outer side.

As a result, when pressurizing the ignition button 5 at the closed position for ignition of the gas burners 23a and 23b, the first protruding piece 51 becomes the prime mover and the cam groove 73 as the driven joint is formed. The adjustment dial 7 is rotated to a predetermined position.

In this case, since the thermal power control dial 7 is rotated using the pressurization operation of the ignition button 5, for example, the spring 17 which is built up between the ignition button 5 and the first portion 11a. It is not necessary to increase the repulsive force of) and the structure of the gas control device can be simplified.

In addition, the wall height of the cam groove 73 is formed so as to become low from one side to the other side according to the pressurization operation of the ignition button 5. Then, when the pressing operation of the ignition button 5 in the closed position is performed, the first projection piece 51 is accommodated in the hole 52 in the longitudinal direction in the cam groove 73 in accordance with the movement of the ignition button 5. Reach the extended flat portion 74.

Then, when the ignition button 5 is pressed, the first protrusion piece 51 accommodated in the hole 52 moves along the flat portion 74 to reach the ignition position. Then, after igniting the gas burners 23a and 23b by activating the discharge unit and releasing the pressurization of the ignition button 5, it is guided to the heart cam mechanism 5b and returned slightly by the repulsive force of the spring 5c. The ignition button 5 reaches the opening position.

The inner circumferential surface of the thermal power control dial 7 is formed on the inner circumferential surface of the thermal control dial 7 in the same plane as the flat portion 74, and the thermal power control dial 7 is clockwise along the rotary guide path 75. Alternatively, rotation is freely counterclockwise.

In this case, the first protrusion piece 51 accommodated in the hole 52 is not engaged with the cam groove 73. Then, when the thermal power control dial 7 is rotated in the clockwise direction, the gas flow rate decreases. When the thermal control dial 7 rotates in the counterclockwise direction, the rotary body 61 is rotated so that the gas flow rate increases.

In this case, in order to limit the rotation range of the thermal power control dial 7, a stopper (not shown) provided on the outer circumferential wall of the base 70a of the thermal power control dial 7 is installed on the main body 21. When rotated counterclockwise until engaging, the second, third and fourth grooves 62b, 62c and 62d coincide with the second, third and fourth communication paths 15b, 15c and 15d, respectively. Thus, the rotor 61 is disposed so that the amount of gas to the gas outlet 16 is increased.

On the other hand, the rotation stop part 76 which the protrusion part 56 provided in the end of the ignition button 5 contacts the rotation guide path 75 in the position where the 1st sheet | seat 62a matches only the 1st communication path 15a. ) (See FIG. 6).

As a result, at the 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 burners 23a and 23b, and maximizes the gas flow rate. Rotation is free only in the thermal power control range between the reinforcement forces that make the thermal power of the gas burners 23a and 23b strong, so that one end of the rotary guide path 75 and the rotary stop portion 76 constitute a rotation range limiting means. do.

Here, for example, a click may be generated at a position where the thermal power of the gas burners 23a and 23b becomes weak and medium so that the cooking power can be easily adjusted by the cooker.

As shown in FIG. 3, the 2nd protrusion piece 54 is provided in the outer peripheral surface of the ignition button 5 facing the 1st protrusion piece 51. As shown in FIG. In this case, the second projection piece 54 having a smaller diameter than the first projection piece 51 is radially outwardly directed to the radial hole 55 provided in the outer circumferential surface of the ignition button 5. By the elastic support.

In addition, radially first and second recessed portions 77 and 78 are formed, respectively, in the engaged state at the predetermined position of the rotation guide path 75. Then, for example, the thermal power control dial 7 is rotated counterclockwise at the minimum flow rate (in this case, the thermal power of the gas burners 23a and 23b is about), so that the second protrusion 54 is the first recess 77. When clicked, a click occurs. In this case, in addition to the first long groove 62a, the second long groove 62b coincides with the second communication path 15b so that the gas flow rate to the gas outlet 16 increases and the thermal power of the gas burners 23a and 23b is increased. Becomes weak.

Then, when the thermal adjustment dial 7 is rotated counterclockwise, when the second recess 78 and the second protrusion 54 are engaged, a click occurs. In this case, in addition to the first and second long grooves 62a and 62b, the third long groove 62c coincides with the third communication path 15c so that the gas flow rate to the gas outlet 16 increases and the gas burner 23a is increased. The thermal power of) 23b is in a medium state.

In addition, the cam groove 73 is formed in the closed position of the ignition button 5 so that the thermal power control dial 7 can rotate clockwise beyond the thermal power control range. When the thermal power control dial 7 is rotated to one end of the cam groove 73 beyond the thermal control range, the first protrusion piece 51 is perpendicular to the pressing direction of the operation button 5 formed at one end of the cam groove 73. It engages with the phosphorus wall part 73a.

This makes it impossible to pressurize and move the ignition button 5 from the closed position to the ignition position without installing a separate operation unit for the child lock mechanism, and a lock position in which the ignition means of the gas burner does not operate is formed. do.

And, when the child lock mechanism is installed, it is good to make it easy for the cook to recognize that the child lock is operating. In this embodiment, as shown in FIG. 7, the window part 7a is installed in the upper part of the thermal power control dial 7 so that a cook may be outstanding, and a red color is displayed at the predetermined position of the rotating body 61 at the same time. . When the thermal control dial 7 was rotated to the locked position, the red display was made to coincide with the window 7a.

Next, the operation of the gas control device 1 of the present invention using the gas burner 23a will be described.

When pressing operation of the ignition button 5 in the closed position shown in Fig. 2, the thermal power control dial 7 is rotated by the action of the first projection piece 51 and the cam groove 73.

In this case, the rotating body 61 is rotated via the gear 72, and in this position, the first, second, and third long grooves 62a, 62b, 62c are the first, second, and third communication paths 15a ( The fuel gas of the gas flow volume which matches each of 15b and 15c and which puts the thermal power of the gas burner 23a into flows to the gas outflow part 16 (refer FIG. 6 (d) and FIG. 11).

If the pressure operation of the ignition button 5 is continued, as shown in Fig. 8, the operation rod 4 is pushed backward through the pressure rod 5a to change the far side and the valve body 32 to the suction piece side. Push to reach the ignition position.

When the ignition position is reached, the ignition operation of the gas burner 23a is performed by the discharge unit. When the flame detection element 26 (see Fig. 1) provided near the gas burner 23a detects the flame of the gas burner 23a, the solenoid valve 3 is excited by a signal from the control unit. Alteration is maintained.

When confirming that the gas burner 23a is ignited and releasing the pressurization of the ignition button 5, the ignition button 5 is guided to the heart cam mechanism 5b to reach the opening position shown in FIG. In the opening position, the far side is maintained open by the pressing action of the operating rod (4) while the thermal power control dial (7) is free to rotate within the thermal power control range.

And counterclockwise until the iron part provided in the outer peripheral wall of the base 70a of the thermal power control dial 7 is engaged with the stopper body 21 in the neutralization position in order to strengthen the thermal power of the gas burner. Direction, the second, third and fourth grooves 62b, 62c and 62d coincide with the second, third and fourth communication paths 1b, 15c and 15d, respectively, and the thermal power of the gas burner 23a is increased. A fuel gas having a gas flow rate of having a steel flows into the gas outlet 16 (see FIGS. 6E and 10).

On the other hand, if the second projection piece 54 is engaged with the first recess 77 to generate a click in order to reduce the thermal power of the gas burner 23a during neutralization, the thermal control dial 7 is rotated clockwise. The gas outflowing part 16 has a gas flow rate in which one or two grooves 62a and 62b coincide with the first and second communication paths 15a and 15b, respectively, and the thermal power of the gas burner 23a is weak. (See FIGS. 6C and 3).

Next, when the thermal power control dial 7 is rotated clockwise until the first projection piece 51 comes in contact with the rotation stop portion 76, the first long groove 62a is provided only in the first communication path 15a. In accordance with this, the fuel gas of the minimum gas flow rate, which makes the thermal power of the gas burner 23a weak, flows to the gas outlet 16 (see Figs. 12 and 6 (b)).

In the case of extinguishing the gas burner 23a, when the ignition button 5 is pressed in the rearward direction from the opening position, the heart cam mechanism 5b is reset, and the ignition button 5 is the repulsive force of the spring 5c. Receives and retreats to the closed position protruding from the thermal control dial (7) shown in FIG.

In this case, the operation rod 4 in which the pressure of the pressure rod 5a is released is moved in the rear direction under the repulsive force of the spring 34 and closes the far side. When the far side is closed, the supply of fuel gas to the gas burner 23a is stopped and extinguished. When the control unit recognizes that the flame is turned off by the flame detection element 26, the solenoid valve 3 is closed.

Finally, when the thermal power control dial 7 is rotated clockwise along the cam groove 73 in the closed position beyond the thermal power control range, the first protrusion piece 51 engages with the wall portion 73a of the cam groove 73 to form a point. The fire extinguishing button (5) becomes unable to pressurize and becomes a child lock.

With reference to FIGS. 13-15, 100 shows the control apparatus which concerns on 2nd Embodiment. For example, when the cooking apparatus overflows from a cooking utensil such as a pot during cooking, each gas controller 100 stops the combustion of the gas burners 23a and 23b by rotating the thermal control dial 7 to one side. It differs from the said 1st Embodiment in the point which it is possible to do so.

In this case, a first projection 501 having a substantially triangular cross section is formed at a predetermined position of the ignition button 5 and at the inner circumferential surface of the thermal power control dial 7 corresponding to the first projection 501. The second protrusion 502 is formed to protrude toward the inside.

The second projection 502 is formed to abut on the first projection 501 when the thermal power control dial 7 is rotated clockwise at the opening position of the ignition button 5 (see Fig. 15 (a)).

In this case, the first long hole 62a of the rotating body 61 coincides only with the first communication path 15a. Therefore, the second projection 502 serves as a rotation stop of the thermal power control dial 7 for setting the minimum gas flow rate to the gas outlet 16.

When the second projection 502 rotates the thermal power control dial 7 clockwise in a position where the second projection 502 abuts on the first projection 501, the second projection 502 is on the inclined surface 501a of the first projection 501. Slides (see Fig. 15 (b)).

In this case, when the ignition button 5 is pressed in all directions and the second projection 502 passes through the inclined surface 501a of the first projection 501, the heart cam mechanism 5b is simultaneously reset (Fig. 15). (c)). In this case, the ignition button 5 receives the repulsive force of the spring 5c and returns to the closed position (see Fig. 15 (d)).

As a result, in addition to extinguishing the gas burners 23a and 23b by pressurizing the ignition button 5, the first and second protrusions 501 and 502 are forcibly moved by the ignition button 5; As a result, the flame of the gas burners 23a and 23b can be extinguished by rotating the fire control dial 7 to one side, thereby improving the use of the gas appliance.

Incidentally, in the first and second embodiments, the thermal power control dial 7 and the rotary body 61 are rotated in synchronization through the gear mechanisms 71 and 72, but the thermal power control dial is not limited to this. The rotating body 61 may be rotated in synchronization with (7).

In addition, as shown in FIG. 16, the motor 8 is provided, the gear 81 attached to the rotating shaft of this motor and the rotating body 61 are engaged, and the rotating body 61 rotates with the motor 8. You may make it possible.

As shown in Fig. 17, the gas burners 23a and 23b may not be extinguished when the gas flow rate is drastically reduced by operating the thermal control dial 7. In this case, the second inner passage 12b between the gas outlet 14 and the flow control valve 6 is partitioned by a diaphragm 9 elastically supported by the spring 91 in the gas outlet 14 direction. The bypass 93 is provided between the chamber 92 in which the partition is separated and the gas outlet 16a of the gas outlet 16.

Then, the diaphragm 9 is moved by the pressure difference between the gas outlet 16a and the gas outlet 14 generated when the gas flow rate is drastically reduced, and the gas staying in the chamber 92 is passed through the bypass passage 93. By supplying to the outlet 16a, misfire of the gas burners 23a and 23b can be prevented.

As shown in FIG. 18, the governor valve 200 which matches the gas pressure of fuel gas between the gas outlet 14 and the flow regulating valve 6 is provided, and as shown in FIG. A solenoid valve 210 separate from the solenoid valve 3 may be added between the outlet 14 and the flow regulating valve 6.

As described above, the gas control apparatus of the present invention can improve the usage method because the gas control device can restrict the movement of the ignition button by rotating the fire control dial to one side without installing a separate child lock control unit. The effect is that the number of parts can be reduced and the cost can be reduced.
