Description

[Detailed description of the invention] (Field of industrial application) This invention is a simple gas stove that supplies gas to a gas burner from a gas cylinder that is removably attached to a part of the appliance body. This invention relates to a gas cylinder setting device that connects to a cylinder connection port provided in a gas cylinder.

(Prior art and its problems) Conventionally, in order to simplify the structure and assembly, this type of device was held directly at the bottom of the container so that it could move forward and backward, and the gas cylinder was pressed and connected to the cylinder connection port by moving forward and backward. It is common to use a direct-mounted cylinder pressing slide member that releases the pressure, and to move it forward and backward from the outside using a cylinder set lever. On the other hand, for ease of operation, the cylinder set lever is a vertically operated type that rotates in an arc around a horizontal axis. In order to make the direct-mounted cylinder pressing slide member as easy to operate as possible using this vertically operated cylinder set lever, a gear and a lever are used, as is known from, for example, Japanese Utility Model Application Publication No. 56-85799. - Various methods have been adopted, such as connecting the two via a link mechanism or through engagement between a cam hole and a pin.

In both simple operation formats, the cylinder pressing slide member is stably advanced and retreated in order to convert the vertical operating force into the forward and backward movement of the cylinder pressing slide member, and is installed in the middle of its movement route, for example, in the gas supply path. If the perpendicular distance to the cylinder set lever pivot point on the instrument block fixed to the bottom plate of the container is not maintained constant at all times, the cylinder pressing slide member may become twisted, rattled, or escape from the vertical operating force. This results in decreased operational efficiency and unstable operation, and also produces squeaking and rattling noises.

If we look at this in the aforementioned public proposal as a conventional example,
The cylinder pressing slide member has a general simple direct-mounting structure in which the center part goes under the bottom plate of the container and slides on the back side of the bottom plate through windows opened at two places on the front and back of the bottom plate, and both ends slide on the top surface of the bottom plate of the container. However, the operation force in the cylinder pressing connection direction, which requires a large operating force, causes the passive end of the cylinder pressing slide member to press the passive end of the cylinder pressing slide member against the bottom plate of the container body. The cylinder pressing slide member is stabilized with respect to the container bottom plate by the gripping action.

However, even if the cylinder pressing slide member is stabilized against the container bottom plate, the container bottom plate itself has weak rigidity in the thickness direction, that is, in the vertical direction, so it bends downward due to the pressing force of the cylinder pressing slide member. This deforms and causes the cylinder pressing slide member to escape relatively largely against the cylinder pressing connection direction operation force from the cylinder set lever on the instrument block, resulting in poor operation efficiency for cylinder setting operations with large resistance, and the cylinder pressing force against cylinder setting operations. A delay in the connection operation causes a feeling of discomfort in operation, and the safe and secure connection of the cylinder is inhibited, or a large operation stroke must be set in anticipation of the escape in order to ensure a safe and secure connection, etc.
There are various drawbacks.

As known from Japanese Utility Model Publication No. 58-10881, a cylinder set lever is pivotally supported and a cylinder pressing slide member operated by the lever is slid against a vertical wall erected on the bottom plate of the container. The cylinder set lever is held movably and the operating force is transmitted from the cylinder set lever to the cylinder pressing slide member in the plane direction where the cylinder set lever and the vertical wall have greater rigidity. A gas cylinder setting device has also been provided that does not have problems with the transmission of operating force.

However, in this device, a vertical wall dedicated to the gas cylinder setting device is purposely erected on the bottom plate of the container body, and necessary parts such as a cylinder setting lever and a cylinder pressing slide member are installed on this vertical wall. Compared to a type that employs a cylinder pressing slide member, not only the structure and assembly are more complicated, but also the weight of the simple gas stove increases by the vertical wall. Vertical walls also have low rigidity in the thickness direction and are particularly prone to tilting when simply installed upright. Due to the directional distance and the deflection distance of the pressure receiving point at the rear end of the gas cylinder from the center line of the gas cylinder, the cylinder connection resistance is perpendicular to the cylinder pressing slide member's tendency to release the cylinder pressing side end to the side. The wall cannot resist. For this reason, similar to the above-mentioned direct-mounted cylinder pressure slide member, there are problems such as poor operational efficiency, resulting in discomfort during operation, and impediment to the safety and reliability of gas cylinder connection. This is a bigger problem than in the case of employing a direct-mounted cylinder pressing slide member because the vertical wall becomes slow to return to its upright state and gradually tilts.

Although this problem in transmitting operating force between the cylinder pressing slide member and the gas cylinder can be solved to some extent by increasing the thickness of the vertical wall sufficiently or by ensuring support, the problem becomes even heavier and more complicated.

On the other hand, it has recently become desirable to incorporate an abnormal pressure safety mechanism into the instrument block, which shuts off the gas supply path in response to abnormal pressure of the supplied gas. However, once the abnormal pressure safety mechanism is activated, it is advantageous for safety to be able to use it without resetting it to the state before activation, but it is inconvenient to perform the reset operation separately. be.

(Purpose) This invention uses a cylinder pressing slide member that is provided to move forward and backward along the bottom plate of the container, and skillfully connects the cylinder set lever, the cylinder pressing slide member, and the reset member of the abnormal pressure safety mechanism. Therefore, it is an object of the present invention to provide a gas cylinder setting device for a simple gas stove, which does not have the drawbacks of the conventional ones.

(Means for Solving the Problems) The present invention comprises a cylinder pressing slide member which is provided so as to be freely movable along the bottom plate of the container body and presses and connects a gas cylinder to a cylinder connection port by moving back and forth and releases the pressing; A cylinder set lever that is connected to the slide member and moves the cylinder pressing slide member forward and backward with vertical arc rotation, and an abnormal pressure safety mechanism that is fixed to the bottom plate of the container and that shuts off the gas supply path in response to abnormal pressure of the gas to be supplied. and an instrument block incorporating the reset cam, a cylinder set lever is pivotally attached to the side of the instrument block, and the cylinder set lever is connected to a reset rod protruding from the reset cam to the side of the instrument block to set the cylinder. The reset cam should be in a position to reset the abnormal pressure safety mechanism only during operation, and the passive end of the cylinder pressing slide member relative to the cylinder set lever should face the lower part of the instrument block, and be placed between the instrument block and the bottom plate of the container body. It is characterized by being wedged in to guide advancement and retreat.

(Function) The present invention has the above-mentioned structure, and the instrument block itself is solid and can firmly support the cylinder set lever. The passive ends of the sandwiched cylinder pressing slide members can be guided between them and moved forward and backward in a stable manner.

Therefore, although the operation is performed by vertical arc rotation, which causes unreasonable movement conversion, stable and nimble operation can be achieved by firmly supporting the operating side, where the unreasonable movement conversion is performed, and guiding the forward and backward movement of the passive side. can be made possible.

In addition, the cylinder set lever is firmly pivoted to the instrument block and connected to the reset lever provided on the instrument block, so that it can be easily and firmly connected to the reset lever, and the cylinder setting and resetting operations can be performed easily. The abnormal pressure safety mechanism can be reset without any special operation through the reset rod and reset cam in conjunction with the cylinder reset operation without affecting the cylinder reset operation.

(Embodiment) To explain the embodiment shown in FIGS. 1 to 4, 1 is a box-shaped container, and a burner chamber 19 in which a gas burner 2 is installed and A small capacity gas cylinder 5 faces the cylinder connection port 4 of the gas supply path 3 and is attached to and detached from the connection port 4.
A cylinder chamber 6 into which the gas is taken in and taken out is formed adjacent to the cylinder chamber 6. An appliance pot 7 and a gas pressure regulator 8 are sequentially provided in the gas supply path 3 from the burner 2 side. The gas pressure regulator 8 is a die-cast product with a cylinder connection port 4 integrally formed therein, and is installed in the cylinder chamber 6 at a position on the front side of the container body 1 with the cylinder connection port 4 facing the rear side of the container body 1. The device block 71 is integrated with the device block 7 made of the same die-cast product, and is fixed to the bottom plate 6a of the cylinder chamber 6 with screws 72 or the like.

The gas cylinder 5 has a nozzle 9 protruding from a small-diameter protrusion 5a at its tip so that it can move forward and backward, and a gas outlet valve 10 that opens and closes in conjunction with the movement of the nozzle 9 into and out of the cylinder 5 is provided in the small-diameter protrusion 5a. It is provided.
On the other hand, the cylinder connection port 4 tightly fits the small-diameter protrusion 5a of the cylinder 5 through the O-ring 11 on the inner circumference, thereby forming an auxiliary seal at the outermost position of the connection port 4 and firmly holding the cylinder 5. cylinder holding hole 12
A nozzle receiving hole 13, which is concentrically opened at the inner part of the holding hole 12 and has a much smaller diameter than the holding hole 12, is provided in two stages. The nozzle 9 of the cylinder 5 is tightly fitted into the nozzle receiving hole 13 via an O-ring 14 on the inner periphery to form an inner seal, and a spring 15 is installed in the inner part.
The nozzle receiving hole 13 of the nozzle 9 is normally closed when
A normally closed check valve 16 is provided (FIG. 4) which is pushed open upon entry into the vehicle.

An annular stepped portion 17 is formed between the cylinder holding hole 12 and the nozzle receiving hole 13, and is formed into an inclined guide surface that slopes inward from the outer diameter side toward the inner diameter side. As a result, when the gas cylinder 5 fitted in the cylinder chamber 6 is pressed and connected to the cylinder connection port 4 by the forward operation of the cylinder pressing slide member 18 provided at the bottom of the cylinder chamber 6 so as to be slidable back and forth, Even if the nozzle 9 were to get caught on the annular step 17, it would be guided to slide into the nozzle receiving hole 13 due to its slope, and would automatically fit into the nozzle receiving hole 13 due to this sliding action. , connection failures like in the past do not occur.

The cylinder pressing slide member 18 is applied to the lower surface of the bottom plate 6a of the cylinder chamber 6, and is held so as to be freely movable back and forth, with both ends 18a and 18b facing the bottom plate 6a through windows 20 at two locations on the front and rear of the bottom plate 6a. One side cover plate 73 of the pressure regulator 8 is attached to the upper cylinder shaft 2 in the part 18a.
A cylinder set lever 22, which is pivotally supported on the cylinder 1, is connected through engagement between an arcuate cam hole 23 and a shaft 24, and is moved back and forth by rotating the lever 22. The lever 22 has an operating portion 22 thereof.
a is made to project to the outside through a vertical slit 25 formed on the front surface of the container body 1, and is moved by a cylinder pressing slide by a spring 26 acting between the cylinder pressing slide member 18 and the raised piece 6b of the bottom plate 6a. Together with the member 18, it is biased in the direction of releasing the pressure on the cylinder 5. The connection between the cam hole 23 and the shaft 24 is achieved by connecting the lever 22 to the spring 2.
6 in the cylinder pressing connection direction (downward), the cylinder pressing slide member 18 is lifted and moved forward while applying force thereto, and by the forward movement of this member 18, The cylinder 5 is pressed by the upward pressing piece 18c at the rear end.
is pushed toward the cylinder connection port 4 for connection. In this connected state, the shaft 24 engages with the engagement recess 27 on the side edge of the end of the cam hole 23, so that the operating lever 22 is moved to the cylinder pressing slide member 1.
Together with 8, the spring 26 is biased in the direction of releasing the pressure on the cylinder, thereby making it more stable. This stability can be sufficiently achieved even without the spring 26 by the restoring force of the cylinder nozzle 9 and the cylinder connection port check valve 16 acting in the cylinder disconnection direction.

The cylinder pressing slide member 18 has a front end 1 which is a passive end with respect to the cylinder set lever 22.
The shaft 2 is attached to the rising passive piece 18d that is bent on the side edge of 8a opposite to the gas burner 2 side.
4 and is engaged with a cam hole 23 formed at the operating end of the cylinder set lever 22, and the front end 18a faces and slides against the lower part of the gas pressure regulator 8 to receive the lifting force. By being guided when the cylinder is moved in the cylinder pressure connection direction, the perpendicular distance of the movement path line to the cylinder set lever pivot point on the gas pressure regulator 8 is kept constant, and the cylinder pressure by the cylinder set lever 22 is maintained constant. The operation in the connection direction is reliably received without any escape, and the operation in the cylinder press connection direction, which requires a large operating force, is achieved efficiently, safely and reliably, and there is no discomfort during operation.

The gas pressure regulator 8 has a plurality of legs 8e that are integrally provided vertically on the bottom surface 8d, and are fixed by screws 72 that are inserted into the bottom plate 6a from below.
d is the part floating from the bottom plate 6a, and the bottom plate 8d and the bottom plate 6
The front end portion 18a of the cylinder pressing slide member is inserted between the
is sandwiched. The front end portion 18a slides on the upper surface of the bottom plate 6a and has an escape window 18e for the leg 8e, and the edge of the escape window 18e slides on a downward step 8f formed on the outer periphery of the lower end of the leg 8e. Then, the gas pressure regulator 8 guides the front end 18a during the operation in the cylinder press connection direction.

Also, when operating in the cylinder pressure release direction, the front end 1
8a is moved in the cylinder pressure release direction while receiving a downward force from the cylinder set lever 22, but the cylinder pressure slide member 18 is moved independently by the biasing force acting in the movement direction. Reduce the push-down force to a level where it has no effect. Even if a large downward force is applied, the front end 18a will be able to secure the legs 8e of the bottom plate 6a to the screws 72.
Since it is firmly guided by the part attracted to the gas pressure regulator 8, there is no escape from the operating force.

The gas pressure regulator 8 is provided with a cylinder connection port 4 on the side opposite to the gas burner 2 side,
And by pivoting the cylinder set lever 22 on the side opposite to the gas burner 2 side,
The connecting point of the lever 22 to the cylinder pressing slide member 18, whose center line coincides with the cylinder connection port 4 when viewed from above, is very close to the center line of the member 18, and the operating force is transmitted from the lever 22 to the member 18. Moreover, it is possible to suppress the member 18 from twisting or wobbling in the horizontal plane direction.

On the front surface of the gas pressure regulator 8, there is a cylinder set prevention stopper 32 which is held movably left and right by fitting elongated holes 30 and 31 into the operating shaft 28 of the instrument handle and the protruding shaft 29 on the front surface of the gas pressure regulator 8. is provided. The stopper 32 is operated by a spring 34 stretched between a protrusion 33 formed on the front surface of the gas pressure regulator 8 so as to fit into the elongated hole 31 and the left side edge of the elongated hole 31. As shown in FIGS. 1 to 3, the tip locking portion 32a enters the downward movement locus of the cylinder set lever 22 and moves the cylinder 5 to the right due to the urging. A downward movement operation to press and connect the connection port 4, that is, a cylinder setting operation is prevented.

A passive bending piece 37 is formed on the stopper 32 and faces a protrusion 36 formed on the back side of the operating knob 35 of the instrument handle 7. Passive bending piece 3
7, when the operation knob 35 has returned to the extinguishing position, it is pushed leftward by the projection 36 to stabilize the stopper 32 in the leftward movement position, and the tip locking portion 32a prevents the operation lever 22 from moving downward. If the operating knob 35 is in the operating position to open the stopper 7 even slightly, the passive bending piece 37 is released from the push by the projection 36 and the stopper 3 is moved out of the trajectory.
2 is moved to the right by a spring 34.

As a result, the cylinder setting lever 22 can be operated to set the cylinder when the appliance pot operating knob 35 is in the extinguishing position, that is, when the appliance pot 7 is closed. When the cylinder is connected, the cylinder setting operation is blocked and the cylinder 5 is connected to the cylinder connection port 4 without knowing that the cooker 7 is opened, causing gas to inadvertently flow out from the burner 2 at the same time as the connection. This will eliminate any inconvenience.

The gas pressure regulator 8 includes a primary side chamber 8a that communicates with the cylinder connection port 4 side of the gas supply path 3, and an instrument pot 7.
and a secondary side chamber 8b communicating with the burner 2 side are partitioned by a diaphragm 38, and a primary side chamber 8a
The gas outlet 8c from the diaphragm 38 to the secondary side chamber 8b is connected to the valve 4 at the tip of the lever 39 which is linked to the diaphragm 38.
0, the cylinder 5 acting in the primary side chamber 8a
The opening degree is adjusted according to the supply gas pressure from the secondary side chamber 8b, so that gas at a constant pressure always flows into the secondary side chamber 8b and is supplied to the burner 2. When the liquefied gas flows out and evaporates, the gas cylinder 5 cools down by being deprived of the heat of vaporization, but in order to provide a stable gas supply, the gas cylinder 5 receives the combustion heat from the burner 2 and is kept at room temperature. Depending on the conditions of use, such as the condition, outside temperature, or direct sunlight,
Excessive temperature rise may occur.

Such excessive temperature rise is extremely dangerous, as it can cause the internal pressure of the cylinder 5 to abnormally increase, exceeding the pressure regulation capacity of the gas pressure regulator 8, causing abnormal combustion, or even causing the cylinder to explode. be. Therefore, when the gas supplied from the cylinder 5 has an abnormal pressure, the gas pressure regulator 8 closes the gas supply path 3 and controls the waste burner 2.
The supply to burner 2 is stopped, and cylinder 5 is now switched to burner 2.
An abnormal pressure safety mechanism 41 is provided to prevent the engine from receiving combustion heat.

The abnormal pressure safety mechanism 41 includes a pressure sensitive chamber 43 into which the primary gas before pressure regulation is introduced through a pilot passage 42 branched from the primary side of the gas supply channel 3, and a pressure sensitive chamber 43 into which the pressure-regulated secondary gas of the gas supply channel 3 is introduced. A diaphragm 45 separates the valve chamber 44 from the valve chamber 44 that passes through the valve chamber 44. On the valve chamber 44 side of the diaphragm 45, a reversing spring 46, which is attached together with the diaphragm 45 and is normally curved in a convex manner toward the pressure sensitive chamber 43 side, is provided. A normally open valve body is provided in the valve chamber 44 with its one end 48a pressed against the reversal spring 46 in the normal position by the biasing force of a spring 47 to maintain an open state away from the valve seat 49 in the middle of the gas supply path 3. 48 is provided, and when abnormal pressure of the supply gas acts on the pressure sensitive chamber 43, the diaphragm 45
is pressed toward the valve chamber 44, causing the reversal spring 46 to move toward the valve chamber 4.
4 side to a convex curved state, and this inverted spring 4
6 is reversed, the valve body 48 is pressed against the valve seat 49 against the bias of the spring 47, and the gas supply path 3 is closed. Reference numeral 50 denotes an O-ring attached to the seating portion of the valve body 48 against the valve seat 49.

A valve body 4 is placed on the opposite side of the valve chamber 44 from the pressure sensitive chamber 43.
8 is a reset rod 5 whose axis is perpendicular to the center of the protruding shaft 21 and whose one end operating portion 51a protrudes to the outside.
1 is fitted and held rotatably. The reset rod 51 has the other end 48b of the valve body 48 on the other end 51b side.
A cam portion 51c is formed opposite to the cam portion 51c. The cam portion 51c is in a flat state with a circular shaft cut off from both sides. One end 51 of the reset rod 51
a is equipped with a passive lever 52 as a non-circular shaft,
By engaging the raised protrusion 22b of the cylinder set lever 22 into the passive window 52a at the tip of the passive lever 52, the lever 22 and the passive lever 52 are rotated integrally.

1 to 5 show the gas cylinder 5 in a reset state. In this state, the cylinder set lever 22 is stabilized at the rotational position shown in the figure, in which the operating portion 22a thereof is at the uppermost position. This stability is achieved as the cylinder pressing slide member 18 is moved to the retreat position by the bias of the spring 26, resulting in a positional relationship in which no rotational force is applied to the cylinder set lever 22 via the shaft 24 and the cam hole 23. It depends.

At this time, the reset rod 51 is rotated together with the cylinder set lever 22 via the passive lever 52, so that the scraped surface _51c1 of the cam portion 51 is oriented horizontally (solid line in FIGS. 2 and 5). Therefore, the non-scraped surface 51c ₂ of the cam portion 51 of the reset rod 51 faces the other end 48b of the valve body 48.
The non-scraped surface 51c ₂ is the outer diameter surface of the reset rod 51, and the distance from the center of the reset rod 51 is much larger than that of the shaved surface 51c ₁ .

Therefore, the non-scraped surface _51c2 is the pressure sensitive chamber 43.
A spring 47 is attached to the reversing spring 46 which is in a curved state convex to the side.
The normally open valve body 4 is pressed by the valve and is in the open position.
8 (solid line in FIG. 2).

In the cylinder non-set state as described above, when the cylinder set lever 22 is moved downward in the direction of the arrow shown in FIG. 5 to move the cylinder pressing slide member 18 to the front side so that the cylinder 5 is set, the cylinder 5 is reset. The rod 51 is also rotated together with the cylinder set lever 22 through the passive lever 52 and rotated approximately 90 degrees. As a result, the cam portion 51 of the reset rod 51 can be turned approximately 90 degrees from the cylinder non-set state, as shown by imaginary lines in FIGS. 2 and 5.

As a result, the cam portion 51 of the reset rod 51
The scraped surface 51c ₁ is the other end 48 of the normally open valve body 48
The direction is opposite to b. This scraped surface 51c ₁
is the one in which the outer diameter surface of the reset rod 51 is shaved off, and the distance from the center line of the reset rod 51 is smaller than that of the unscraped surface _51c2 , so the second
As shown by the imaginary line in the figure, the other end 48b of the normally open valve body 48
A space S necessary and sufficient for the normally open valve body 48 to close is created between the two.

Normally, the normally open valve body 48 is in an open position where it is pressed against a spring 47 by a reversing spring 46 which is curved in a convex manner toward the pressure sensitive chamber 43 side. On the other hand, the reversal spring 4
6 is reversed to a curved state convex to the valve chamber 44 side in response to an abnormal rise in gas pressure for some reason while the cylinder 5 is set and in use, and the normally open valve body 48 is held by the spring 47. trying to resist and retreat. At this time, the other end 48a of the normally open valve body 48
Since the space S is created between the cam portion 51c of the reset rod 51, the normally open valve body 48 can be retracted, and does not interfere with the reversing action of the reversing spring 46. As a result, it is retreated to the closed position to prevent gas from flowing out in the event of an abnormal pressure increase, thereby ensuring safety in use.

Once the reversal spring 46 is reversed to the curved state convex toward the valve chamber 44 side, it will not return to the original curved state convex toward the pressure sensitive chamber 43 side. Therefore, it is impossible to resume use.

To return the reversing spring 46, press the reset lever 5.
Perform a reset operation using 1. This will be explained. Move the cylinder set lever 22 upward to return to the cylinder set position shown in the figure. At this time, the reset rod 51 is also rotated together with the reset rod 51 and returned to the position indicated by the solid line in FIGS. 2 and 5.

As a result, the cam portion 51 of the reset rod 51
The non-shaved surface 51c ₂ comes to face the other end 48b of the reset rod 51, and the scraped surface 51
It protrudes toward the normally open valve element 48 by an amount equal to or close to the space S than _c1 , and pushes the normally open valve element 48 toward the reversing spring 46. At this time, the normally open valve body 48
pushes back the reversing spring 46, which has been inverted to the curved state convex toward the valve chamber 44 side, toward the pressure-sensitive chamber 43 side, and returns the reversing spring 46 to the curved state convex toward the pressure-sensitive chamber 43 side. In this state, when the cylinder set lever 22 is operated downward to set the cylinder 5, the cylinder will be in the normal operating state as shown by the phantom lines in FIGS. 2 and 5.

In the figure, 53 is a mounting screw for the stopper 32;
4 is a snap spring for preventing the passive lever 52 from coming off.

Furthermore, the burner 2 has a main body 2a having an annular gas receiving chamber 55 opened upward at the upper end.
The main body 2 is fitted into the upward opening portion 55a of the annular gas receiving chamber 55 and secured with screws 56 to the main body 2a.
The head 2b has an outer flame hole 57 formed between it and the head 2b, and the head 2b is provided with an inner flame hole 57a. In the main body 2a, a mixing pipe 58 communicating with the annular gas receiving chamber 55 is integrally formed at the lower part of the annular gas receiving chamber 55. The mixing tube 58 is provided sufficiently long so as to cross the lower part of the main body 2a so that the amount of protrusion from the main body 2a is small, and
A connecting end 58a with the gas supply path 3 protruding from the
The diameter gradually increases from 1 to 58b to the communication part 58b with the annular gas receiving chamber 55, and within the long mixing pipe 58 with this gradual increase in diameter, the gas supplied to the burner 2 weakens as it reaches the communication part 58b. At the same time, the air is sufficiently mixed with the outside air which is sucked in under negative pressure at the connecting end 58a.

In addition, the communication portion 58b of the mixing tube 58 with the gas receiving chamber 55 is far away from the ignition position where the ignition plug 59 of the burner outer flame hole 57 is disposed close to, due to the length of the mixing tube 58. The outflow of the supply gas from the outer flame hole 57 located at the ignition position is delayed compared to the outflow from other parts, and the ignition operation is delayed accordingly. This has the disadvantage that the ignition may be delayed for a while, or the ignition may not ignite during the first opening operation, and the user must realize this and hastily perform the opening operation to ignite the ignition. In order to solve this problem, a bypass path 60 is provided from the mixing pipe 58 to the gas receiving chamber 55 on the side where the ignition of the main body 2a is performed.
is formed to speed up the outflow of gas from the flame hole 57 on the side of the ignition part, so that ignition is not delayed.

61 is a lid that closes the punching hole 58c for forming the mixing tube 58, 62 is a soup saucer, 63 is a trivet, 64 is a cylinder chamber lid, 65 is a pivot of the lid 64, and 66 is an air intake passage for the inner flame of the burner 2. It is.

(Effect of the invention) According to this invention, the cylinder set lever is pivotally attached to the side of the instrument block, and the cylinder press operated by the cylinder set lever is provided between the instrument block and the bottom plate of the container to which it is attached. The slide member is sandwiched with its passive end facing toward the cylinder set lever to guide the forward and backward movement of the passive end, and the instrument block itself is solid and can firmly support the cylinder set lever. In addition, it is possible to guide the passive end portion of the cylinder pressing slide member firmly attached to the container bottom plate and sandwiched between the container bottom plate and move it forward and backward in a stable manner.

Therefore, when the cylinder pressing slide member, which moves forward and backward along the bottom plate of the container body, is moved forward and backward along the bottom plate of the container by means of an easy-to-operate cylinder set lever which is rotated vertically in an arc, the cylinder pressing slide member is moved forward and backward with movement conversion. Although it is operated by arc rotation, stable and nimble operation is possible by firmly supporting the operating side, where the foregoing forced movement conversion is performed, and guiding the passive side forward and backward.

Furthermore, since the cylinder set lever is firmly pivoted to the instrument block and connected to the reset rod extending from the reset cam of the abnormal pressure safety mechanism provided in the instrument block, it can be easily and firmly connected to the reset rod. The abnormal pressure safety mechanism can be reset without any special operation through the reset rod and reset cam in conjunction with the cylinder reset operation without affecting the cylinder setting and resetting operations.

The cylinder set lever, the cylinder pressing slide member, and the reset rod can be easily connected, and the structure does not become complicated and does not cause an increase in cost.
