[Gas circuit for gas burner 2]

7 is an explanatory diagram of a gas circuit 21 and a control circuit thereof to the gas burner 2.

In the gas circuit 21, the solenoid safety valve 22, the one-way valve 23, the on-off valve 29, and the flow regulating valve 24 are sequentially arranged on the upstream side, and at the same time, the on-off valve 29 is closed. When the heat setting valve 26 is opened, it is possible to supply more gas to the gas burner 2 than the maximum amount of gas that can be supplied by the flow rate control valve 24 alone in the open / close valve 29. Specifically, when the on-off valve 29 is opened and the flow rate control valve 24 is set to the maximum opening degree, an amount of gas capable of burning the gas burner 2 at 3500 Kcal / h can be supplied. On the other hand, in a state where the special thermal power setting valve 26 is opened by closing the on-off valve 29, an amount of gas capable of burning the gas burner 2 at 4000 Kcal / h can be supplied.

In addition, the control device 36 for controlling the electronic safety valve 22, the special fire power setting valve 26, etc., burns the ignition button 11 and the special fire power setting operator 14, or the gas burner 2. The thermocouple 35 which monitors a state is connected. In the present embodiment, the one-way valve 23 correspondingly opens and closes each time by the push-pushing mechanism described later each time the ignition button 11 is pressed. Further, whenever the special thermal power setting operator 14 is pressurized, the special thermal power setting valve 26 is opened and closed correspondingly by the control device 36. Then, the control device 36 controls the opening / closing state of the opening / closing valve 29 for supplying gas to the flow rate control valve 24 in the open / closed state opposite to the special thermal power setting valve 26, thereby setting the special thermal power. When the valve 26 is opened, the on-off valve 29 is closed so that the gas amount regulating function is not operated by the flow regulating valve 24.

[Valve Unit]

The electromagnetic safety valve 22, the original valve 23, and the flow regulating valve 24 are assembled to the valve unit 8 shown in Figs.

The front end of the casing 81 of the valve unit 8 is provided with a mover 83 in contact with the back side of the above-mentioned ignition button 11, and the mover 83 passes through the spring 82. It is elastically supported in the fire button 11 direction. The rod 84 is pressed against the elastic bearing force of the spring 85 by the movable element 83, and the rear end of the rod 84 is the valve body 22a of the electromagnetic safety valve 22. In the middle of the rod 84, the valve body 23a of the one-valve 23 is provided.

The mover 83 is reciprocated between the rear final position in the pressing direction and the initial position before pressing by the push-pushing mechanism 86, and the return operation at the final position is stopped at the intermediate position. It is. Therefore, when the ignition button 11 is pressed, the rod 84 is pushed back through the mover 83, and the one-way valve 23 is opened and at the same time the electronic safety valve 22 is opened. maintain. When the pressing operation of the ignition button 11 is released in this state, the mover 83 is returned to the intermediate position in the pressing direction by the push-pushing mechanism 86. In this intermediate position, the pressurization of the solenoid safety valve 22 is released, but the solenoid safety valve 22 is kept open by the electromotive force of the thermocouple 35 as described above, and the original valve 23 is the rod 84. To keep the pressure open.

As a result, the gas burner 2 maintains a combustion state. When the ignition button 11 is pressed again, the locking at the intermediate position of the mover 83 is released. As a result, the mover 83 is returned to the initial position, and the original valve 23 is closed to close the gas burner 2. ) Is extinguished, and the electromagnetic safety valve 22 is also closed because the electromotive force of the thermocouple 35 is lost.

Then, the push-push mechanism 86 is composed of a cam mechanism 860 having a substantially hard shape, as shown in FIG. 5, which is formed on the mover 83, and an engaging member 861 engaged with it. The known hard cam type is adopted. When the movable member 83 moves from the initial position to the final position by the one-turn pressing operation (ignition operation) of the ignition button 11, the engaging member 861 moves from the a point of the cam mechanism 860 to the b point. When the pressing force is released at the final position, the engaging member 861 moves from point b of the cam mechanism 860 to point c so that the mover 83 is locked at the intermediate position. Further, when the engaging member 861 moves from the point c of the cam mechanism 860 to the point d by the two-turn pressing operation (digestion operation) of the ignition button 11, and the release force is released in this state, the engaging member 861 ) Is returned to point a, and the mover 83 is returned to the initial position. Further, the cam mechanism 860 moves the ignition device to the gas burner 2 when the front and rear distances of the points a and d are moved to positions corresponding to the points a and b. Therefore, the gas burner does not pass through the position corresponding to the point b when the mover 83 moves in the path corresponding to the point c-> d point-> a point. The ignition to furnace (2) does not work.

In this embodiment, when the ignition button 11 is pressed during the ignition operation and the fire extinguishing operation, a limit switch (not shown) is operated to output an opening signal for opening the special thermal power setting valve 26. Therefore, if the ignition button 11 is pressurized (it becomes a ignition operation) in the state in which the special thermal power setting valve 26 is open, the special thermal power setting valve 26 will close by the said closing signal, and heat control by this will be performed. The firepower set by the handle S is returned.

In addition, the flow regulating valve 24 assembled to the valve unit 8 includes a needle-type valve body 240 in which rotation and shank-dong are freely inserted into the upper end of the vertical path 87 formed in the casing 81. ). The cap 88 (refer FIG. 3, FIG. 4) is attached to the upper end of the vertical path 87, and the elongate inclined guide hole 88a is formed in the left and right walls of this cap 88. As shown in FIG. A pin 88b protruding from the upper left and right walls of the flow regulating valve 24 is inserted into the guide hole 88a.

In addition, a fire control lever 51 is attached to the shaft 91 at the top of the cap 88, and the pins 88b are interposed between both side portions of the base end of the fire control lever 51. Fork portion 51a is bent downward. As a result, when the thermal power control lever 51 is rotated, the pin 88b is integrally rotated with the flow rate control valve 24 to be guided to the guide hole 88a to move up and down, and the gas supply amount to the gas burner 2 is increased or decreased. And, at the distal end of the thermal control lever 51, a thermal control knob S, which is the above-described operation handle for sliding along the slit 12 formed on the front surface of the stove body 1, is mounted.

On the other hand, when the ignition button 11 for igniting the gas burner 2 is pressed, the thermal control lever 51 is turned to the ignition position (in this embodiment, the thermal control lever 51 is a slit 12 for sliding. A mechanism for forcibly moving to the reinforcement position, which is the left end portion of, is assembled to the valve unit 8. This mechanism is comprised by the interlocking lever 80a by which the rotation was freely attached to the support shaft 90 on one side of the phase part 89 of the casing 81, as shown to FIG. The interlocking lever 80a has a pin penetrating the transverse portion 80c and the flow regulating valve 24 opposite to the projection 83b (see Fig. 6) projecting rearward on the upper part of the movable member 83 in the transverse direction. An action point portion 80d opposite to 88b is formed. According to this, when pressurizing the ignition button 11 for burning the gas burner 2, when the movable element 83 is pressed back to the back from the position corresponding to point d of FIG. 5 described, the protrusion 83b ) Is in contact with the stationary portion 80c of the interlocking lever 80a and the interlocking lever 80a swings. Thereby, the working point part 80d of the interlocking lever 80a contacts the pin 88b, and the pin 88b rotates simultaneously with the flow regulating valve 24. As shown in FIG. Then, the pin 88b is guided to the guide hole 88a shown in Figs. 3 and 4 and ascends, thereby moving the flow rate adjusting valve 24 to the reinforcement position, which is the ignition position.

[actual use]

Next, the actual use state of the gas stove will be described.

First, when the pot 9 is placed on the pedestal G and the ignition button 11 is pressed, the thermal power adjusting knob S is ignited by the mechanism of the valve device 8 (in this embodiment, thermal power control). The handle S is forcibly moved to the reinforcement position, which is the left end of the slide slit 12, and the solenoid safety valve 22 and the one-way valve 23 are opened. In addition, when the ignition button 11 is pressed, the special thermal power setting valve 26 is closed and the on-off valve 29 is opened by the closing signal of the limit switch (not shown). Therefore, when the special thermal power setting valve 26 is opened before the ignition button 11 is pressurized, it is closed and the on-off valve 29 is opened, whereby the amount of gas suitable for the ignition (this embodiment In the form, the gas amount corresponding to the reinforcement is supplied to the gas burner 2, and in this state, an ignition device (not shown) is operated, and the gas burner 2 starts combustion. Then, the solenoid safety valve 22 is kept open by the output of the thermocouple 35 which monitors the flame of the gas burner 2, and combustion of the gas burner 2 is continued by this.

In this state, the thermal power control knob S is slid so that the heat 9 when the pot 9 placed on the pedestal G is heated can be set to the highest thermal power.

Specifically, when heating the pot 9 made of flat bottom stainless steel having a diameter of 30 cm, the thermal power adjusting knob S is set to the first size indication 63a. Then, as mentioned above, the gas burner 2 is burned by the thermal power which can raise the thermal efficiency at the time of heating the pot 9 made of the flat bottom stainless steel of diameter 30cm. In addition, in the case of heating the aluminum pot 9 which is different from the pot 9 and the material only, the thermal power control knob S is fitted to the material mark 64 adjacent to the first size mark 63a. And when heating the round bottom aluminum pot 9 of 30 cm in diameter, the thermal power control knob S is matched with the material display 64 of the adjacent part of the 1st size display 63a. In the case of heating the round bottom stainless pan 9 having a diameter of 30 cm, the thermal power adjustment knob S is placed on the shape display 65 of the adjacent portion of the first size display 63a provided below the slit 12. Fit. In the same manner, even when the pot 9 having a diameter of 15 cm to 25 cm is used, the second to fourth size marks 63b to 63d correspond to the combination of the diameter (pot size), the material, and the bottom shape of the pot. The heat control knob S is fitted to the material display 64 and the shape display 65 provided in these adjacent parts. Thereby, the gas burner 2 burns with the thermal power which can raise the said thermal efficiency of the pot used to the maximum, and the gas stove with high thermal efficiency can be obtained.

On the other hand, when the special thermal power setting operator 14 is inputted, the special thermal power setting valve 26 shown in Fig. 7 opens and the on-off valve 29 is closed, thereby exceeding the amount of gas that can be supplied to the flow regulating valve 24. An amount of gas is supplied from the special thermal power setting valve 26 to the gas burner 2, and the gas burner 2 is burned with a special thermal power exceeding the maximum force settable by the thermal power control knob S. Therefore, the thermal power setting which can heat especially the large pot 9 is possible.
