In this locked state, when the cylinder 15 is inserted and the stopper 37 is pushed in by the flange 23 of the cylinder 15 against the urging force of the spring 36, the stopper 37 retreats from the advance / retreat movement passage of the operating body 21, and the stopper 37 stops. The locked state of 37 and the lock engagement piece 25 is released.

This embodiment is configured as described above.
Next, the operation will be described. First, in a state where the cylinder 15 is not accommodated in the cylinder holes of the cylinder bodies 11 and 12 which are the cylinder accommodating portions (a state where the operation knob 17 is at the combustion stop position),
The sliding rod 34 of the stopper device 30 advances into the forward / backward sliding passage of the operating body 21 by the urging force of the spring 36, and the stopper 37
The operation knob 17 is fixed to the combustion stop position, and cannot rotate in the ignition direction since the operation member 21 is prevented from moving in the advance direction by being locked by the lock locking piece 25.

In this state, the lid 13 is inserted from the inlet side of the cylindrical holes 11 and 12.
When the cylinder 15 is opened and the cylinder 15 is inserted, the flange 23 of the cylinder 15 abuts against the distal end surface 38 of the stopper 37 and the sliding rod 34 is pushed in the retreating direction. At the same time, the cylinder 15 is stored in a predetermined position, and the lid 13 is closed. In this state, since the locked state of the stopper 37 and the lock engagement piece 25 has been released, the operation knob 17 can be operated in the ignition direction, and when the operation knob 17 is turned in the ignition direction, the operation knob 17 is released. The driving wall portion 28a of the power transmission portion 28 provided is a link portion of the operating body 21.
As shown in FIG. 3B, the locking claw 24 is moved from the cylinder 15
And the cylinder 15 is locked. In this state, the burning operation of the burner 5 is performed. However, even if the cylinder 15 is to be taken out while the stove is in use, the cylinder 15 cannot be removed because the flange 23 is locked by the locking claw 24 as described above. Thus, the danger caused by removing the cylinder during combustion is reliably prevented.

To extinguish the burner 5, the operation knob
Turn 17 to the combustion stop position. Due to the rotation of the operation knob 17 in the return direction, the drive wall portion 28b of the operation knob 17 is locked to the linking portion 27 and slides the operating body 21 in the retreating direction. By this retreating, the locking claw 24 moves to a position separated from the flange 23 of the cylinder 15, so that the locked state of the locking claw 24 and the flange 23 is released, and the cylinder 15 can be pulled out.

When the cylinder 15 is pulled out, the sliding rod 34 of the stopper 30 is pushed by the spring 36 to enter the advance / retreat movement area of the operating body 21, and the stopper 37 is locked by the lock locking piece 25 to be in a locked state. Then, the movement of the operating body 21 in the advance direction is prevented, and the operation knob 17 is fixed so as not to rotate in the ignition direction.

According to the present embodiment, when the cylinder 15 is removed from the accommodation portion of the cylindrical bodies 11 and 12, the stopper 37 is
Since the operation knob 17 is locked, the operation knob 17 does not rotate in the ignition direction. Therefore, when the cylinder 15 is inserted, the operation knob 17 is always in the combustion stop position, so that it is very safe.

When the operation knob 17 is turned in the ignition direction, the engaging claw 24 is engaged with the flange 23 of the cylinder 15 to prevent the cylinder 15 from coming off. Therefore, the problem that the gas leaked from the removed cylinder catches fire is reliably prevented.

Further, when the operation knob 17 is set to the combustion stop position and the lid 13 is opened to take out the cylinder 15, the cylinder 15 is pushed in the removal direction by the stopper 37 by the urging force of the spring 36. The projecting portions 11 and 12 project outward from the entrances, and the projecting portions can be gripped, so that the cylinder 15 can be easily extracted.

Further, the cylinders 11 and 12 of this embodiment are

Even when the stopper device 30 is omitted, even if the operation knob 17 is turned in the ignition direction, even if the cylinder 15 is to be
24 enters the insertion passage of the cylinder 15, and as shown in FIG. 3A, the locking claw 24 locks on the front end surface of the flange 23 of the cylinder 15 to prevent further insertion of the cylinder 15. Therefore, the cylinder 15 cannot be stored in a predetermined position, and after the operation knob 17 is set to the combustion stop position and the cylinder 15 is stored,
Attempting to remove the cylinder 15 during ignition and combustion operation,
As shown in (b), the locking claw 24 is locked on the back surface of the flange 23 of the cylinder 15 so that the cylinder 15 cannot be pulled out. Therefore, the cylinder 15 is always put in and taken out when the operation knob 17 is at the combustion stop position, that is, in a state where the locking claw 24 is retracted from the insertion passage of the cylinder 15, which is very safe for use on the stove. . However, when the stopper device 30 is omitted, with the cylinder 15 removed,
You can no longer lock 21.

In the above embodiment, a pair of cylinders 11 and 12 are provided on the left and right sides of the frame 7 of the cassette stove. However, one of these cylinders may be provided on one side of the frame 7; May be provided with three or more cylinders. Also, the shape of the cylinders 11 and 12 is not necessarily limited to a cylindrical shape, and may be an arbitrary shape such as a square.

[0027]

According to the present invention, when the operation knob is turned in the ignition direction, the cylinder cannot be stored, and the stored cylinder cannot be taken out. Is performed when the fuel is in the combustion stop position, and is very safe in handling.

Further, the safety operation such as prevention of the cylinder from coming off when the operation knob is turned in the ignition direction is configured to be performed in conjunction with the operation knob. Since a complicated mechanism linked to the operation of the lever is not required, the simplification of the device configuration is achieved, and the manufacture of the device becomes very easy. Further, the operation of the safety operation is also very easy.

Furthermore, in the configuration provided with a stopper for locking the operating body when the cylinder is removed, the operation knob does not turn in the ignition direction when the cylinder is not stored. When doing so, it is necessary to ensure that the operation knob is in the combustion stop position, so that the safety when the cylinder is stored can be further improved.
