Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a portable gas stove to be used outdoors, by providing a slide mechanism on a gas burner,
It is designed to obtain a large firepower.

[Prior Art] In recent years, outdoor activities such as camping have become popular, and there are many opportunities to use a gas stove outdoors. As such a gas stove, a table type gas stove 1 as shown in FIG. 16 is conventionally known. The gas stove 1 includes gas burners 3 and 3 arranged side by side in a casing 2. On the front surface of the casing 2, the heat power adjusting knobs 4 and 4 of the gas burners 3 and 3 are arranged, respectively, and a carrying handle 5 is arranged. Further, a grill 6 and a soup tray 7 are placed on the upper opening of the casing 2. In the soup saucer 7, crater outlets 11, 11 are formed,
The crater of the gas burner 3 can be taken out. A lid plate 8 for closing the upper opening of the casing 2 is rotatably connected to the rear edge of the upper surface of the casing 2. Side plates 10 and 10 that cover both sides of the upper opening of the casing 2 are rotatably connected to the inner surfaces of both ends of the cover plate 8 so that the cover plate 8 and the side plates 10 and 10 can be opened respectively. It is configured to act as a windshield in the state.

[Problems to be solved by the invention] By the way, in the gas stove shown in Fig. 16, generally, liquefied petroleum gas, white gasoline, kerosene, etc. are used as the fuel. Among them, liquefied petroleum gas is widely used because it is light in weight and is filled in a cartridge, so that it is extremely portable.
However, the gas stove using this liquefied petroleum gas has a problem that its fire power is weaker than that using white gasoline or kerosene. Further, a gas stove using liquefied petroleum gas as a fuel has a problem that its thermal power becomes weaker due to continuous use. This is because the latent heat when the liquefied petroleum gas vaporizes cools the cartridge and the liquefied gas, and the vaporization amount of the fuel gas from the cartridge decreases.

The present invention has been made to solve the above problems, and an object thereof is to provide a gas stove that is excellent in portability and has a high heating power.

[Means for Solving the Problems] A portable gas stove according to the present invention is a portable gas stove in which a plurality of gas burners are vertically arranged in a casing, and a liquefied gas fuel cartridge is connected and fixed to each gas burner. At least one of the lined gas burners is provided with a slide mechanism capable of sliding the crater of the gas burner, and a plurality of gas burners can be used in close proximity or in contact with each other.

[Operation] Even if each gas burner has a weak heating power,
Since each crater is slidable by the slide mechanism, a plurality of craters can be assembled to obtain a strong firepower.

[Example] Hereinafter, the present invention will be described in detail with reference to specific examples.
The portable gas stove of the present invention is not limited to these examples.

(Embodiment 1) FIG. 1 shows an embodiment of a portable gas stove according to the present invention. The difference between the one shown in FIG. 1 and the conventional one shown in FIG. 16 is that an elliptical crater outlet 9 is formed in the soup tray 7 and a slide mechanism 11 (not shown) is attached to the gas burner 3. The crater of the gas burner 3 is slidable inside the crater outlet 9. The crater outlet 9 is formed so that the crater of the gas burner 3 which is slidable by the slide mechanism 11 can be taken out from any portion of the juice tray 7, and in the example shown in FIG. Is formed in an oval shape because the gas burner 3 is slid linearly toward both end portions of the casing 2. As shown in FIGS. 2 to 6, the slide mechanism 11 is generally composed of a slide plate 12 attached to the gas burner 3 and slide plate guides 13 and 13 attached to the casing 2. is there.

A gas burner 3 suitably used in the portable gas stove of the present invention is shown in FIG. The gas burner 3 includes a gas cartridge 14, an instrument plug block 15, a gas pipe 16, an air-fuel mixing pipe 17, and a crater forming member 18. The gas cartridge 14 is a closed container filled with gas fuel in a liquefied state. For example, liquefied petroleum gas or the like can be preferably used. Further, the instrument plug block 15 is for supplying the gas pipe 16 while vaporizing the liquefied gas from the gas cartridge 14, and the gas pipe 16 is provided via a valve body (not shown) which is interlocked with the thermal power adjustment knob 4. Are lined up.
The gas pipe 16 is a pipe body that is erected from the side surface of the instrument plug block 15, and is an air-fuel mixing pipe that mixes gas fuel and air.
It communicates with the cap-shaped crater forming member 18 via 17. A slide plate 12 is provided on the bottom surface of the gas pipe 16 along the sliding direction of the gas burner 3. The slide plate 12 is a rectangular plate body that is inserted into two pairs of slide plate guides 13 and 13 'extending on the inner surface of the casing 2.
As shown in FIGS. 4 and 5, the slide plate guide 13,
Slide the gas burner 3 between the 13 'and the casing 2
It can be freely moved inside. The slide plate guides 13 and 13 ′ are composed of two pairs of plate bodies that are parallel to each other, and extend on the inner side surface of the casing 3 along the sliding direction of the gas burner 3. These two pairs of slide plate guides 13 and 13 'face each other with a width slightly larger than the thickness of the slide plate 12, and the slide plate 12 is inserted therebetween. Furthermore, this slide plate guide 13, 1
As shown in FIG. 4, stoppers 19 and 19 ′ are provided at 3 ′ so as to be perpendicular to the sliding direction of the gas burner 3.
Is provided. The stoppers 19 and 19 'are not particularly limited as long as they are members for restricting the moving range of the gas burner 3. However, as shown in FIGS. 5 and 6, for example, a bar shape such as an angle bar is used. You can use your body. As shown in FIG. 5, the stoppers 19 and 19 are prevented from being damaged by the contact between the crater forming members 18 and 18 when they are slid so that the craters of the gas burners 3 and 3 come into contact with each other. In order to prevent it, it is arranged at a distance longer than the diameter of the crater forming member 18. In addition, the stopper 19 '
As shown in FIG. 6, 19 ′ is provided to prevent the gas burners 3 and 3 from falling off from the casing 2 when they are slid.

When heating two different pans using the portable gas stove 1 as described above, as shown in FIG.
The gas burners 3 and 3 are used in a separated state. That is, it can be used exactly like a conventional portable gas stove. Further, when heating with strong heat power is required, at least one gas burner 3 is slid toward the other gas burner 3 and, as shown in FIG.
To be in the proximity state. At this time, since the slidable range of each gas burner 3, 3 is regulated by the stoppers 19, 19, the respective crater forming members 18, 18 do not overlap with each other.
In this way, the craters of a plurality of gas burners can be easily gathered in one place. Therefore, even if the thermal power of each gas burner 3 is weak, the thermal power as the sum of the thermal power of each gas burner can be obtained, so that a strong thermal power can be obtained.

(Embodiment 2) FIG. 9 shows a second embodiment of the portable gas stove according to the present invention. What is shown in FIG. 9 is different from that shown in FIG. 1 in the shape of the crater outlet 9 and the slide mechanism 20 of the gas burner 3. For short.

In this example, three gas burners 31, 32, 33 are arranged in parallel, and the slide mechanisms 20, 20 are attached to the two gas burners 32, 33 adjacent to each other. The slide mechanism 20 is fixed to the front inner surface of the casing 2 and serves to fix the gas burners 32 and 33 and to slide the crater. The slide mechanism 20 includes a clamp portion that holds the gas pipe 16, a vertical rotation shaft that extends vertically from the clamp portion, and a bearing portion that is fixed to the lower surface of the juice receiving tray 7 to receive the vertical rotation shaft. Consists of. By such a slide mechanism 20, the gas burners 32, 33 are axially supported on the lower surface of the soup tray 7 so as to be rotatable in the horizontal direction about the vertical rotation axis. Gas burner 3 supported by such a slide mechanism 20
Both 2 and 33 can be slid so as to draw an arc with the vertical axis as the center and the gas pipe 16 as the radius.
Therefore, the soup tray 7 is formed with a curved crater outlet 9 formed by bending an oval according to this locus. As shown in FIGS. 10 and 11, the stoppers 21 and 21 'are composed of two pairs of angle bars separated by the rotation angle of the gas pipe 16, and the gas is formed by the angle formed by each angle bar. The tube 16 is rotatable.

In such a portable gas stove, in normal use, as shown in FIG. 10, the gas pipes 16 are kept parallel to each other, but when a large heating power is to be obtained, as shown in FIG. , Each of the gas pipes 16, 16 of the gas burners 32, 33 is rotated in the direction of the other gas burner to form a crater forming member.
Place 18 and 18 in close proximity or in contact.

The shape of the crater forming member of the portable gas stove shown in FIG. 1 and FIG. 9 was a substantially annular cap shape, but the portable gas stove of the present invention is not limited to these. For example, an oval type, a concavo-convex type, a nested type or the like can be used.

FIGS. 12 to 15 show a preferred example of these crater forming members in a state where each gas burner is separated from each other,
The figure also shows the state of proximity or contact. The crater forming members 18, 18 shown in FIG. 12 and FIG. 13 are all oval, and the crater forming members 18, 18 are
Since the integral crater is formed in the state where they are brought close to or brought into contact with each other, it is possible to obtain a larger heating power than that shown in FIGS. 1 and 9.

Further, the examples shown in FIG. 14 and FIG. 15 are designed so that a larger fire power can be obtained when the gas burners 3, 3 are brought close to or brought into contact with each other. The example shown in FIG. 14 is a circular crater forming member 18 and an arc-shaped crater forming member 18 ′ that surrounds the outer periphery of the crater forming member 18. Further, FIG. 15 shows that the crater forming members engage with each other when they are brought close to each other or brought into contact with each other.
This is an example in which a generally U-shaped nesting type is used. When the crater forming member having such a shape is used, when the gas burners 3 and 3 are brought close to or brought into contact with each other, the crater forming members 18 and 18 'are combined with each other to form a circular or rectangular crater. The crater can be further concentrated toward the bottom of the pan or the like to be heated, and a large amount of heat can be efficiently used.

[Effects of the Invention] As described above, the portable gas stove of the present invention is provided with a slide mechanism on at least one of the gas burners, so that a plurality of gas burners can be used in the proximity or contact state. Even if the heating power of each gas burner is weak, a strong heating power can be obtained by assembling a plurality of burners.
