The gas control device G is provided in a gas supply path 12 extending from the outlet of the cock 4 to the main nozzle 6c.
For example, the structure is as shown in FIG.

The gas control device G includes an upper portion communicating with a gas inlet pipe 15 connected to an outlet side passage 12a of the cock 4 in a gas supply path 12 of the rotary cock type blinker E through a gas inlet hole 16.

A valve housing F having a structure in which a liquid sealing chamber 34 is formed in a cylindrical portion 23 between a lower end surface of a needle valve and the partition wall 26, which will be described later, and is vertically connected with a partition wall 26 having a slow timing adjusting hole 25 interposed therebetween. Is established,

A needle valve V is vertically slidably provided in the upper and lower valve chambers 17 and 20 of the valve housing F. When the needle valve V moves up and down, the oblique valve portion 27 and the valve seat 21 are moved.
The needle valve V is provided with an orifice hole 29 for restricting the flow rate to a predetermined medium heat gas amount,
When the needle valve V is fully closed at the upper limit position in the figure, the gas flowing from the gas inflow pipe 15 through the gas inflow hole 16 into the upper valve chamber 17 passes through the inflow hole 28 of the needle valve V through the central vertical hole 28a and the orifice hole 29. Thus, the gas amount is reduced to about medium fire and flows from the gas outlet hole 19 to the gas outlet pipe 18.

A sliding cylinder 30 is integrally provided above the needle valve V, and a pushing shaft 31 is provided in the sliding cylinder 30.
And pushes the pushing shaft 31 upward by a first spring 32 having a predetermined spring force mounted in the sliding cylinder 30 to push the pushing shaft 31 against the sliding cylinder 30. The sliding cylinder 30 is inserted into the tubular portion 22 integral with the upper valve chamber 17 of the valve housing F so as to slide freely. Penetrates the upper part of the cylindrical part 22 and projects upward,

It has become.

With reference to FIG. 3, a specific operation when the cooking device according to the present invention is applied to a gas stove provided with a rotating cock type flickering device in the above configuration will be described below.

In the ignition operation, when the ignition knob 1 is pushed by a predetermined stroke and then turned to the "open" position, the main burner 6 is ignited. At this time, the cock shaft 13 is fixedly provided only in the rotational direction. Operating cam 14
First, the push shaft 31 of the gas control device G is pushed down by a predetermined stroke (a → b) between the inclined cam surfaces A → B, and the first spring 32 is compressed by the push shaft 31. At this time, the needle valve V is regulated by the restraining force of the liquid damper H and does not immediately move, and the opening of the needle valve V is in a fully closed state (see the state from the state A to the state B in FIG. 3). Therefore,
When the cam surface changes from A to B, the opening degree of the cock 4 is set to medium heat, but the cock 4 continues to rotate. However, the gas from the gas inlet to the gas inflow pipe 15 through the outlet side passage 12a of the cock 4 is supplied to the gas inflow hole 16 → the upper valve chamber 1
7 → the inflow hole 28 of the needle valve V → the middle vertical hole 28a and the orifice hole 29 restricts the gas amount to a medium fireable gas amount which can be ignited, and the gas outflow hole 19 → gas outflow from the lower valve chamber 20. Since the main burner 6 is supplied from the main nozzle 6c to the main burner 6 via the pipe 18 → the gas passage 12b, the main burner 6 is ignited with a gas amount of about medium heat.

Thereafter, the cam surface of the operating cam 14 is changed from B → C.
→ The first spring 3 compressed by the pushing shaft 31 during the period from D to D
The needle valve V is pushed down by a constant pushing force due to the spring force of No. 2, but at this time, the needle valve V descends slowly due to the suppressing force by the liquid damper H. That is, the first
When the needle valve V is depressed with a constant pressing force by the spring force of the spring 32, the liquid 36 having a small thermal expansion coefficient sealed in the liquid enclosing chamber 35 is depressed by the depressing force.
Flows into the pressure regulation chamber 24 from the slow timing adjustment hole 25 and pushes down the pressure regulation valve against the second spring 39. Therefore, since the constant pressing force by the first spring 32 is suppressed by the liquid damper H, the pressing speed of the needle valve V by the spring force of the first spring 32 becomes slow,
The opening between the bevel valve portion 27 of the needle valve V and the valve seat 21 gradually widens (see the state from C to D in FIG. 3). Therefore, after ignition is performed with a gas amount of about medium fire by the orifice hole 29 at the time of closing the needle valve, the gas amount due to the opening degree of the needle valve V gradually expanding to the gas amount of about medium fire also causes a slow timing. Finally, when the cock 4 is fully opened, the amount of gas reaches a high-fire level, and the main burner 6 shifts from medium-fire combustion to high-fire combustion.

In the fire extinguishing operation, the ignition knob 1 is turned off.
Is turned to the position shown in FIG.
4 also rotates and its cam surface is displaced in the order of D → C → B → A, so that the pushing force of the pushing shaft 31 is released. Accordingly, the pushing shaft 31 is raised together with the needle valve V via the liquid damper H by the spring force of the second spring 39 and moves to the original position (FIG. 3).
A) to prepare for the next ignition operation.

Next, in the embodiment shown in FIGS. 4 and 5, in a gas stove provided with a push / push type flashing device, the gas control device G is changed by a change in a use state such as loading and unloading of a pot in use. The gas stove, which is operated to ensure safety, is equipped with a push and push-type flasher. When the ignition button 101 is fully pressed at the time of ignition, the main valve 102 and the magnet valve 103 are simultaneously opened, and the When the switch S is turned on, an igniter (not shown) operates to ignite the main burner 104. Thermocouple 105
Detects the burner flame f, the magnet valve 103 is attracted and held in an open state by the electromagnet 106 '. Thereafter, when the ignition button 101 is released, the ignition button 101 is slightly returned and locked, and the main valve 102, the magnet valve 103
Is open, and the main burner 104 continues combustion.

At the time of fire extinguishing, when the ignition button 101 is pressed again,
The lock is released and returns to the original position, the main valve 102 closes, and the main burner 104 extinguishes. When the thermocouple 105 senses that the main burner 104 has extinguished, the magnet valve 103 is also closed. Note that the heating power of the main burner 104 is adjusted by moving the heating power adjustment lever 106 left and right, and the needle valve 107 moves to adjust the amount of gas supplied to the main burner 104.
The minimum gas amount is the bypass hole 10 provided in the needle valve 107.
8 and the thermal power adjustment lever 106 is "weak"
When the ignition operation is performed in the state described above, the return lever 109 moves the heating power adjustment lever 106 to the "medium" position to ignite with the "medium" heating power. In the above gas stove,
Reference numeral 110 denotes a burner main body of the main burner 104, 111 denotes a burner head, 112 denotes a burner, 113 denotes a main nozzle, 114 denotes a gas inlet, and 115 denotes a pot.

In the gas stove provided with the push / push type flickering device, the gas control device G is installed in the central secondary air hole 116 of the burner head of the main burner 104, and the pushing shaft 31 of the gas stove 112 is When the pan 115 is put on and unloaded, it is arranged so as to move up and down by a certain stroke by pushing down and releasing the pushing down by the bottom of the pot, and the gas passage 11 from the blinker 117
8 is connected to a gas inflow pipe 15, and a gas passage 119 to the main nozzle 113 is connected to a gas outflow pipe 18. The structure of the gas control device G is the same as that of the gas control device G except that the orifice hole 29 that restricts the flow rate of the gas provided in the needle valve V to a predetermined flow rate has an opening area that reduces the gas amount to about a low heat. Since the other structures are the same as those of the gas control device of the previous embodiment, the same parts are denoted by the same reference numerals and description thereof will be omitted.

With reference to FIG. 5, a specific operation when the cooking device according to the present invention is applied to a gas stove provided with a push / push flashing device in the above configuration will be described below.

When the pot 115 is placed on the gotoku 112 and the stove is used by the heat of the high heat, the pushing shaft 31 of the gas control device G is pushed down by a fixed stroke (a → b) on the bottom of the pot 115. As a result, the opening of the needle valve V is fully opened as shown in FIG.

[0033] Then, with the stove on fire, Gotoku 1
When the pan 115 on the top 12 is moved from above or removed from the cooking stove, the pushing of the pushing shaft 31 of the gas control device G by the bottom of the pot is released. , Quickly rises together with the needle valve V via the liquid damper H and returns to the original position (see the state A in FIG. 5), so that the opening of the needle valve V is fully closed and the orifice hole 2
The main burner 104 burns only with the gas amount of about 9 to 9 which is a low heat. Therefore, the main burner 104 has a heating power of about low heat.

When the pot 115 is put on the gotoku 112 again,
On the bottom surface of the pan 115, the pushing shaft 31 of the gas control device G is pushed down by a fixed stroke (a → b), and the pushing shaft 31 compresses the first spring 32. At this time, the needle valve V does not move immediately due to the restraining force of the liquid damper H,
The opening of the needle valve V is in a fully closed state (see the state from the state A to the state B in FIG. 5). Therefore, the main burner 10
No. 4 burns at a low heat level when the pot 115 is placed on the gotoku 112.

That is, the gas from the gas inlet 114 flows from the gas passage 118 of the blinker 117 to the gas control device G via the gas inflow pipe 15, and the gas inflow hole 16 → the upper valve chamber 17
→ The inflow hole 28 of the needle valve V → follows the path of the central vertical hole 28a and the orifice hole 29 narrows the gas amount to a gas amount of low heat, and the gas outlet hole 19 → the gas outlet pipe 18 → the gas passage from the lower valve chamber 20. 119 and the main nozzle 11
Since the main burner 104 is supplied to the main burner 104 from the third, the main burner 104 burns with a heating power of about a low heat when the pot 115 is placed on the stove.

After that, the first compressed shaft 31
The needle valve V is pushed down by a constant pushing force by the spring force of the spring 32, but at this time, the needle valve V slowly descends by the suppressing force of the liquid damper H. That is,
When the needle valve V is pushed with a constant pushing force by the first spring 32, the liquid 3 having a small coefficient of thermal expansion in the liquid sealing chamber 35
6 flows into the pressure regulation chamber 24 from the slow timing adjustment hole 25 of the partition wall 26 and pushes down the pressure regulation valve 37 against the second spring 39. Therefore, the constant pressing force of the first spring 32 is suppressed by the liquid damper H, and the speed at which the needle valve V is pressed down by the spring force of the first spring 32 is performed slowly against the suppressing force of the liquid damper H. ,
The degree of opening between the bevel valve portion 27 of the needle valve V and the valve seat 21 is gradually widened (see the state from C to D in FIG. 5). Therefore, if the pot 115 is placed again on the gas stove 112 during use, the pot power is initially about low heat, but then gradually becomes high heat combustion power.

The operation of the gas control device G described above for slowly increasing the heat after medium-ignition ignition and the operation of moving the pot from the stove during use or removing the pot quickly with a low heat when the pot is re-mounted and The operation of slowly setting a high heat is performed by continuous operation for a short time, so that there is no problem in use.

The suppression force of the liquid damper H is determined by the opening area of the slow timing adjusting hole 25. As a result of an experiment, in the case of the liquid sealing chamber 35 of 8φ, the slow timing adjusting hole 25 has a diameter of about 0.25. It was appropriate. The allowable spring force of the first spring 32 and the second spring 39 is set to a spring force that can reliably perform each of the above gas controls.
