Description of the Related Art Generally, when supplying gas to a burner of a gas appliance, the gas is injected at high speed from a nozzle into a mixing pipe located upstream of the burner, and the ejector effect of the injection of the gas surrounds the nozzle. The air is sucked into the mixing pipe, the gas and the air are mixed in the mixing pipe at an appropriate ratio, and the mixture is supplied to the burner. In such a type of gas appliance, the amount of injection of gas is controlled to be increased or decreased to adjust the thermal power, but when the amount of injection of gas is increased or decreased, the intake amount of air also changes accordingly. That is, if the injection amount of gas decreases, the intake amount of air also decreases, and conversely, if the injection amount of gas increases, the intake amount of air also increases, and the air-fuel ratio of the air-fuel mixture increases regardless of the injection amount of gas. Is kept constant.

によりバーナにおいて失火するおそれがある。However, if the thermal power is adjusted suddenly, the air-fuel ratio may deviate from the normal value transiently. In particular, when the heat power is suddenly reduced from high to low, the rate of gas decrease becomes faster than the rate of air decrease, the mixing ratio of gas to air decreases, and the air-fuel mixture itself also decreases. There is a risk of fire.

スの減少速度が遅くなりバーナでの失火が防止される。Since the throttle valve is biased toward the low heat position by the biasing means, when the operating mechanism is rapidly operated to the low heat operating position, the throttle valve tends to move to the low heat position by the biasing means. When the throttle valve is moved to the low heat position, high speed movement is restricted by the restriction means, so the throttle valve cannot follow the operating speed of the operating mechanism, and at least when the operating mechanism reaches the low heat operating position. The throttle valve reaches only the position where the heat power is stronger than the low heat position. From this position, the high-speed movement is restricted by the restricting means, and the gas is moved to the low-fire position by the urging force of the urging means, whereby the reduction rate of the gas is slowed and misfire in the burner is prevented.

る。The restriction means may be any means as long as it restricts the high speed movement of the throttle valve. For example, in the case of the structure described in claim 2, when the throttle valve moves toward the low heat position. The protrusion comes into contact with the inclined portion, and a frictional force is generated between the protrusion and the inclined portion as the throttle valve moves to the low heat position.
The frictional force reduces the speed and restricts the high-speed movement of the throttle valve.

る。Alternatively, when the restricting means is composed of a fixing member and a viscous body that fills the sliding clearance, shear stress acts on the viscous body due to the movement of the throttle valve so that the viscous body is dashed. Acts as a pot. That is,
Since the force acting from the viscous body on the throttle valve in the deceleration direction increases in proportion to the moving speed of the throttle valve, even if an attempt is made to rapidly move the throttle valve toward the low heat position by the biasing force of the elastic means. The force of the viscous body in the deceleration direction brakes the movement of the throttle valve, and slowly moves toward the low heat position.

If the intermediate member is allowed to move as described in claim 5, the displacement of the throttle valve with respect to the fixed member can be absorbed by the movement of the intermediate member with respect to the fixed member.

置まで移動する。According to the sixth aspect of the present invention, when the operating mechanism is rapidly operated to the low heat operating position, the viscous force of the viscous body causes the intermediate member to slide integrally with the throttle valve toward the low heat position of the throttle valve. As a result, the operation mechanism can be operated lightly. Then, after that, the reaction force of the urging means causes the intermediate member to slide back toward the high-fire position of the throttle valve, and when the stopper stops the movement of the intermediate member, all the urging force of the urging means. It acts on the throttle valve and slowly moves to the low-fire position while the high-speed movement is restricted by the restriction means.

にした。According to the fourth aspect of the invention, when the throttle valve is returned from the low heat position to the high heat position, the restriction force by the restriction means acts. Therefore, a differential member is provided as described in claim 7, and the differential member is moved relative to the intermediate member together with the throttle valve by the restricting force of the restricting means that acts when the throttle valve moves to the high-fire position. The throttle valve is moved to the high-fire position only by the operating force that can withstand the second biasing force.

Gas supplied from a main port 11 is supplied from a supply passage 12 to a nozzle. It is configured to supply to the burner a mixture of ambient air and gas that is injected into the mixing pipe 42 via 41 and sucked by the ejector effect. This device is a well-known device in which the electromagnetic safety valve 15 is opened when the fire extinguisher 13 for extinguishing the burner is pushed, and the main valve 16 is held open by the push-push mechanism 14.

Sliding body 13 pushed against spring 13a by pushing
The rod 15a of the electromagnetic safety valve 15 and the rod 16a of the original valve 16 are pushed from the tip surface of b, and both the electromagnetic safety valve 15 and the original valve 16 are opened. Here, when the push operation on the fire extinguisher 13 is released, the sliding body 13b is pushed back by the urging force of the spring 13a, but the locking pin 14b is locked at the intermediate locking position of the heart cam groove 14a formed in the sliding body 13b. As a result, the sliding body 13b is temporarily locked at an intermediate locking position on the way. At this time, the rod 16a of the main valve 16 is in contact with the tip end surface of the sliding body 13b and is in the open state.
On the other hand, although the rod 15a of the electromagnetic safety valve 15 is separated from the above-mentioned tip end surface, it is adsorbed by the thermoelectromotive force of a thermocouple (not shown) and held open. Further, when extinguishing the fire, by pushing the fire extinguisher button 13 again, the locking pin 14b is released.
Moves from the intermediate locking position of the heart cam groove 14a, and the sliding body 13b returns to the original position by the urging force of the spring 13a.
As a result, the main valve 16 is closed and gas is not supplied to the burner to extinguish the fire. Then, the thermoelectromotive force from the thermocouple disappears and the electromagnetic safety valve 15 is not held open and is closed.

溝22にも挿通されている。The increase / decrease control of the amount of gas supplied from the supply passage 12 to the burner is performed by moving the throttle valve 17 up and down. It is set so that when the throttle valve 17 rises, the gas passage area of the portion where the throttle valve 17 is provided expands, and conversely when the throttle valve 17 descends, the passage area narrows. The throttle valve 17 is provided with a pin 17a protruding therefrom. The pin 17a is inserted into a cam window 19 formed in a guide plate 18 which is a fixing member. The throttle valve 17 is contracted between the guide plate 18 and the throttle plate 17. It is urged downward by the spring 3, which is the urging means.

に沿って位置aまで上昇移動する。The shape of the cam window 19 is as shown in FIG. 2, and when the lever 2 is in the high-fire operation position and the pin 17a is in the position a corresponding to the high-fire position of the throttle valve 17, the lever 2 is slowly and gently fired. When operated to the operation position, one side edge 22b of the long groove 22 moves the pin 17a to the left side in the drawing. At this time, the throttle valve 17 is biased downward by the spring 3, so that the pin 17a moves along the hypotenuse b of the cam window 19, and when the lever 2 is operated to the low heat operation position, the low heat position of the throttle valve 17 is reached. To position c corresponding to. However, when the lever 2 is rapidly operated from the high heat operation position to the low heat operation position, the throttle valve 17 is urged downward by the spring 3, but the pin 17a passes through the locus away from the hypotenuse b to the side edge 22b. When the pushed pin 17a comes into contact with the vertical side e of the cam window 19 and the lever 2 is operated to the low heat operation position, it passes through the position c and reaches the position g on the high heat side of the low heat position of the throttle valve 17, After that, the oblique side d, which is the restricting means by the biasing force of the spring 3,
Position c corresponding to the low heat position of the throttle valve 17 while still in contact with
Descend to. At this time, the pin 17a is decelerated by the frictional force generated between the pin 17a and the hypotenuse d, and reaches the c relatively slowly without descending at a high speed. When the pin 17a moves slightly from the position d to the position c in the lateral direction and the side edge 22b of the lever 2 does not hinder the returning operation of the pin 17a, the relief portion 22d is inclined below the long groove 22 as shown in the drawing. It was formed. That is, although the throttle valve 17 is urged downward by the spring 3, the urging force is not so strong as to move the lever 2, and thus the escape portion 22d is formed in this way, so that the pin 17a is at the intermediate position. The lever 2 is not moved by the spring 3 even if the hand is released from the lever 2 while being in contact with the oblique side b. By the way, when the lower portion of the long groove 22 is slanted, the oblique side 22a is formed, but the oblique side d of the cam window 19 is formed.
May be cut off and the oblique side 22a may be used as the regulation means. In order to change the heat power from low heat to high heat, the lever 2 is operated from the low heat position to the high heat position side.
a is pushed by the other side edge 22c of the long groove 22, and the oblique side b
Along the line, move up to the position a.

The throttle valve 17 moves to the position c corresponding to the low heat position, and the throttle valve 17 changes from the state shown in (i) of FIG. 6 to the state shown in (iii) of FIG. When the lever 2 is rapidly operated, the pin 17a leaves the hypotenuse b,
It is forcibly lowered to a midway position h at a high speed until it comes into contact with the vertical side e along a substantially parallel oblique side f with a predetermined distance from the oblique side b. At this time, since the relative speed between the throttle valve 17 and the bush 4 is restricted by the adhesive grease, the bush 4
Is lowered together with the throttle valve 17, and the lever 2 can be lightly operated, resulting in the state shown in FIG. 6 (ii). In this state, there is nothing to restrain the upward movement of the bush 4, so that the bush 4 is pushed up by the urging force of the spring 3 and the flange 42 contacts the guide plate 18. Then, since the bush 4 is prevented from further rising, the urging force of the spring 3 acts on the throttle valve 17, and the throttle valve 17 uses the force obtained by subtracting the deceleration force by the adhesive grease from the urging force of the spring 3 to the intermediate position h. Slowly descends to the position c corresponding to the low heat position. The cam window 1 having the shape shown in FIG.
When 9 is used, it is possible to squeeze at a high speed up to a position where misfire does not occur, which is convenient for squeezing operation.

Means that the pipe 5, which is a differential member, is interposed between the bush 4 and the cylindrical protrusion 32, with the sliding clearances 41 and 51 interposed between both the bush 4 and the cylindrical protrusion 32. Fill only 51 with adhesive grease. It should be noted that the bush 4 is provided with a flange 42 as in the case of FIG. 6, the pipe 5 is provided with a spring receiving portion 52 at one end, and the other end is an engaging means for engaging with the bush 4. The claws 53 are formed on the same circumference at intervals, for example, at four positions in this embodiment, and when the pipe 5 is assembled to the bush 4, the claws 53 are temporarily bent inward and inserted. Further, the spring 31, which is the second urging means, is contracted between the flange 42 and the spring receiving portion 52. In this case, the cam groove 19 and the long groove 22 have the same shapes as those shown in FIG.

れる。With this structure, when the lever 2 is slowly operated from the high-fire operating position toward the low-fire operating position, the pin 17a in the cam window 19 moves from the position a corresponding to the high-fire position of the throttle valve 17 to the hypotenuse b. Along with this, the throttle valve 17 moves to the position c corresponding to the low heat position, and the throttle valve 17 changes from the state shown in (i) of FIG. 8 to the state shown in (iii).
When the lever 2 is suddenly operated, since the claw 53 is engaged with the bush 4, the bush 4 and the pipe 5 move as a unit, and the throttle valve 17 changes from the state shown in (i) of FIG. 8 to (ii). Move to the state shown. Then, the bush 4 and the pipe 5 are integrally pushed up by the urging force of the spring 3, and the flange 42 of the bush 4 contacts the guide plate 18,
After that, the throttle valve 17 slowly descends to the low heat position by a small force obtained by subtracting the deceleration force by the adhesive grease filled in the sliding clearance 51 from the urging force of the spring 3. Next, when the lever 2 is operated from the low heat operation position to the high heat operation position to raise the throttle valve 17 in the low heat position toward the high heat position, as shown in FIG. The pipe 5 ascends together with the throttle valve 17 while compressing the spring 31 due to the restriction force of the adhesive grease. At this time, since the sliding clearance 41 is not filled with the adhesive grease, the restriction force by the adhesive grease does not act on the lever 2 but only the compression force of the spring 31 acts, and therefore the biasing force of the spring 31 is extremely high. If it is set to a small value, the lever 2 can be operated from the low heat operation position toward the high heat operation position with a smaller force than in the case of the configuration shown in FIG. Then, after the lever 2 is operated to the high-fire operating position and the throttle valve 17 is moved to the high-fire position, the restoring force of the spring 31 causes the pipe 5 to engage the claw 53 with the upper end of the bush 4 in the state shown in (i). Returned to.
