Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating body positioning / falling prevention structure applied to a stove equipped with a cassette cylinder.

[0002]

2. Description of the Related Art A stove used in a camp or the like generally uses a cassette cylinder.
In this type of stove, the cassette cylinder itself is cooled by the heat of vaporization accompanying the consumption of the liquefied gas in the cassette cylinder. For this reason, there is a problem that the temperature is lowered to near the boiling point of the liquefied gas and the vaporization ability is lowered. Therefore, conventionally, a heating element has been used, and the heat of combustion is used to heat the cassette cylinder to solve the above problem.

As the heating body, there are a type fixed to the stove body and a type fixed to the cassette cylinder itself. The former heating element has a structure in which a part of the heating element can be fixed to the upper surface of the stove body by screwing or fitting, while the latter heating element has locking parts at its upper and lower ends. The both locking portions are configured to be locked so as to sandwich the upper and lower edge portions of the cassette cylinder.

[0004]

However, in the former heating body, since the heating body is in direct contact with the stove body, the combustion heat is radiated through the stove body, and the heat transfer efficiency is not good. Further, in the latter heating body, it is possible to make it not in contact with the main body of the stove, but the mounting work of the cassette cylinder is troublesome. In the latter case, the heating element may fall, so a preventive structure is required.

Therefore, it is an object of the present invention to provide a heating body positioning / falling prevention structure which can effectively transfer combustion heat to a cassette cylinder and which can be easily mounted.

[0006]

In order to achieve the above object, in the present invention, there is provided a heating rod which penetrates through a through hole formed in a stove body without contacting the stove body and has an upper end located in a combustion section. A heating surface is provided with a curved surface that comes into contact with a side surface of a cassette cylinder detachably attached to the stove body, and the curved surface has a magnet attracted to the cassette cylinder so as to maintain the contact state. A portion is provided, and a lock receiving portion for locking the lower end edge portion of the cassette cylinder is formed at the lower end portion.

It is preferable that the curved surfaces of the heating body are formed on both sides of the heating body, and the side surfaces of the cassette cylinders juxtaposed in contact with the respective curved portions.

The through-hole of the stove body is formed of a small hole through which the heating rod can penetrate and a large hole through which a hooking portion provided on the heating rod can penetrate. When locked, the hooking portion is above the eyelet portion,
Moreover, it is more preferable that the centers thereof do not coincide in the vertical direction.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in FIG. 1, the heating body 14 having the positioning / falling prevention structure according to the present invention is attached to a cassette cylinder 2 attached to the stove body 1.

The stove body 1 has a structure in which a top plate 4 is provided on a substantially rectangular frame body 3. Communication holes 5 are formed in the top plate 4 at two positions on the left and right, and burners 6 are provided therein. A cassette cylinder attachment portion 7 is formed below the burner 6, and the cassette cylinder 2 is detachably attached thereto. Reference numeral 25 denotes an ignition device that also serves as a valve. By igniting the ignition device, the gas in the cassette cylinder 2 can be supplied to the burner 6 through a pipe (not shown) and burned above it. The top plate 4 has a shape capable of forming a recess on the upper surface of the stove body 1, and a plurality of wire rods 4a are bridged between both side edges. Further, a substantially keyhole-shaped through hole 8 is formed in the top plate 4 adjacent to each of the communication holes 5 (see FIG. 2B). Large hole 9
Is a size through which the fastener 22 provided on the heating rod 20 described below can be inserted, and the small hole portion 10 is a size through which the heating rod 20 can be inserted without contact but the fastener 22 cannot be inserted. . Further, foldable leg portions 11 are provided from both sides of the frame body 3, respectively, and when the leg portions 11 are extended downward, the mounted cassette cylinder 2 does not come into contact with the ground. In addition, 12 is a cover and a windshield,
Reference numeral 13 denotes an auxiliary windshield plate rotatably attached to both edges of the cover / windshield plate 12. The auxiliary windshield plate 13 can be folded toward the cover / windshield plate 12 side, and the cover / windshield plate 13 can be further folded toward the frame body 3 side.

The heating body 14 has curved surfaces 15 on both sides, the curved surfaces 15 having a shape along the side surface of the cassette cylinder 2. A rectangular hole 16 is formed in the curved surface 15 so as to open on both sides, and a permanent magnet 17 is embedded therein by a magnet holding portion 17a. A yoke 18 made of a rectangular magnetic plate is arranged on both sides of the permanent magnet 17.
Both edges of 8 are flush with each curved surface 15. Also,
A locking groove 19 that opens laterally is formed at the lower end of the heating body 14 along the curved surface 15. The locking groove 19 is formed to have a width and a depth so that the curling portion 2a formed on the lower end edge of the cassette cylinder 2 can be locked. Further, a heating rod 20 extends upward from the upper end of the heating body 14. The heating rod 20 is made of, for example, a material having a high thermal conductivity, such as copper, and has a groove portion 21 formed in the circumference at the upper end thereof, and a substantially C-shaped fastener 22 is attached thereto. Has been.

The heating element 14 having the above structure is mounted between the cassette cylinders 2 and 2 mounted on the cassette cylinder mounting portion 7 of the stove body 1 as follows. That is, the heating rod 20 and the fastener 22 are made to project upward from below with respect to the large hole portion 9 of the through hole 8 formed in the top plate 4. After that, the cassette cylinders 2 and 2 are brought into contact with the curved surfaces 15 formed on the side surfaces of the heating body 14 to be positioned, and are attached to the cassette cylinder attachment portion 7. In this state, the center of the fastener 22 and the center of the large hole 9 are vertically displaced, the yoke 18 is attracted to the side surface of the cassette cylinder 2, and the curling portion 2a of the cassette cylinder 2 is engaged with the locking groove 19. Stop. As a result, the mounting state of the heating element 14 becomes strong, and it does not fall off during normal use. Further, even if the heating body 14 comes off due to the action of external force or the replacement of the cassette cylinder 2, the fastener 22 provided on the heating rod 20 is adapted to be caught in the small hole portion 10 of the through hole 8. Therefore, the heating body 14 does not fall off from the stove body 1, and an accident such as the heating body 14 dropping and hitting a foot does not occur.

The heating element 14 attached in this way
Then, when the heating of the object to be heated is started by ejecting and burning the gas in the cassette cylinders 2 and 2 from the burner 6, the combustion heat is transferred from the heating body 14 to the cassette cylinder 2 via the heating rod 20. To be As described above, the heating body 14 does not come into contact with the top plate 4 of the stove body 1 through the through hole 8 in the state where the heating body 14 is attached to the cassette cylinder 2, so that the combustion heat is smoothly transferred to the cassette cylinder 2. It does not cause problems such as poor combustion due to the low temperature of the cylinder.

In the above embodiment, the case where the heating element 14 is attached to the side surfaces of the two cassette cylinders 2 has been described, but it goes without saying that the present invention can be applied to the case where one cassette cylinder 2 is attached. In that case, the curved surface 15 may be provided on only one side.

[0016]

As is clear from the above description, according to the heating element positioning / falling prevention structure of the present invention, the heating element can be locked to the stove body without contact.
The combustion heat can be effectively transferred to the cassette cylinder,
It is possible to supply a desired amount of fuel gas to the combustion section and perform appropriate heating.

Further, since the curved surfaces are formed on both sides of the heating element and the magnet portion is exposed on each curved surface, it is possible to heat two cassette cylinders together, which is efficient.

Further, since the heating rod is provided with a hooking portion, even if the heating body is detached from the cassette cylinder, the hooking portion is caught by the key hole formed in the stove body and does not fall. . Therefore, there is no need to worry about dropping onto the foot, which is excellent in safety.
