BACKGROUND OF THE INVENTION The present invention relates to a cassette stove,
It is suitable for carrying on a tabletop stove at home or outdoors, and is used with a replaceable cassette cylinder in which a flammable gas is press-fitted.

[0002]

2. Description of the Related Art Conventionally, there has been a replaceable cassette cylinder as a stove having a relatively simple structure for use in a tabletop stove at home. As shown in FIGS. 5 to 7, a cylinder housing portion 4 for housing a cassette cylinder A in which a liquefied gas is press-fitted is provided inside one side of a case 2'having a substantially rectangular plane, and the case 2'is formed. The combustible gas supplied from the cassette cylinder A is moved by the governor 5 when the dial knob 3 rotatably mounted on the front of the cassette is rotated.
The burner 6 which is ignited or extinguished via the
It is a structure provided in the approximate center of the inside.

In use, when the dial knob 3 is rotated, the combustible gas press-fitted into the cassette cylinder A is supplied to the burner 6 through a valve provided in the governor 5. In addition, when the dial knob 3 is rotated,
The combustible gas is ignited by the function of the piezoelectric element and the combustible gas from the cassette cylinder A is used for combustion. When the cassette stove is extinguished during combustion, when the dial knob 3 is rotated in the opposite direction to that at the time of ignition, the valve provided in the governor 5 is closed, and the cassette cylinder A
The supply of the combustible gas from the burner 6 to the burner 6 is stopped and the fire is extinguished.

[0004]

However, the conventional cassette stove shown in FIGS. 5 to 7 is provided with a cylinder storage portion 4 inside one side of a case 2'which is formed in a substantially rectangular shape in plan view. The structure is such that the cassette cylinder A is housed in the portion 4 for use, and since the Gotoku 8 is placed on the upper surface of the burner 6 for use, its height is relatively high and the stove itself becomes large. It was difficult to transport, and it was necessary to secure a large installation area during use and storage.

Moreover, the cassette cylinder A is stored in the cylinder storage unit 4
If the dial knob 3 is erroneously operated after being loaded inside, the combustible gas may leak from the burner 6 or may be ignited, which is dangerous. Therefore, in order to prevent this danger, it is necessary to provide a safety device, but the structure is complicated and the manufacturing and assembling cannot be easily performed, and the manufacturing cost is high.

In view of the above, the present invention makes the stove itself compact and easy to carry, saves space during use and storage, and even if the dial knob is erroneously operated, combustible gas is emitted from the burner. The object of the present invention is to ensure high safety without leakage, to simplify the structure without providing a special safety device, and to reduce the manufacturing cost.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 is a stove main body, A is a cassette cylinder in which a flammable gas is press-fitted, and this cassette cylinder A
Is exchangeably housed in the stove body 1. The stove body 1 has a dial knob 3 rotatably mounted on the front surface thereof, and a case 2 formed of a thin metal plate or the like.
And a cylinder housing portion 4 for housing the cassette cylinder A in a replaceable manner inside the case 2, and a combustible gas supplied from the cassette cylinder A by a turning operation of the dial knob 3 via a governor 5. A burner 6 having a large number of gas ejection holes for substantially igniting or extinguishing the interior of the case 2 and a hole 7a disposed above the burner 6 and facing the burner 6 are provided. The soup tray 7 and the Gotoku 8 placed on the upper surface of the soup tray 7 for use have the same structure as the conventional cassette stove shown in FIGS. 5 to 7.

However, in the present embodiment, the case 2 is formed in a substantially square shape in a plane having a depth dimension l ₁ substantially the same as that of the conventional case 2 ', and the juice receiving tray 7 is also made in a substantially square shape in the plane. Gokutoku 8 is attached to the upper surface of the soup saucer while being provided over substantially the entire area of the case 2. Moreover, the juice receiving tray and the Gotoku 8 are different from the above-described embodiment in that they are placed on the upper surface of the case 2 so as to be reversible when not in use, and that the cylinder storing section 4 is provided below the juice receiving tray 7.
To attach the soup saucer 7 of Gotoku 8
Adhesion may be performed using an adhesive, fitting, caulking, or the like.

Reference numeral 9 denotes the soup tray 7 and the cassette storage section 4
Is a heat shield plate provided in the case 2 between the heat shield plate 9 and the heat shield plate 9. The heat shield plate 9 is formed of a metal plate and blocks direct heating by the heat from the burner 6.

Reference numeral 9a designates two flat, oblong insertion holes provided at an angle K on the diagonal lines I and I'of the soup saucer 7, and the Gotoku attached to the soup saucer is inverted when not in use. By being mounted on the upper surface of the case 2 as much as possible, a part of the fitting hole 9a, for example, two mounting parts 8a having a substantially L-shaped side surface can project into the cylinder housing part 4.

An embodiment of the present invention has the above-mentioned configuration,
The case 2 is formed in a substantially square shape in a plane having a depth dimension l ₁ which is substantially the same as that of the conventional case 2'shown in FIGS. 5 to 7, and the juice tray 7 is also formed in a substantially square shape in a plane. Since the cylinder container 4 is provided over substantially the entire area of the container and below the juice tray 7, the cylinder container 4 is provided on one side of the case 2'which is substantially rectangular in plan view as shown in FIGS. It is smaller than the conventional cassette stove in which the above is provided, and the installation area during use or storage is reduced (see FIGS. 1 and 2).

Further, when not in use, the soup tray 7 to which the Gotoku 8 is attached is placed on the upper surface of the case 2 in an inverted state, so that the flat horizontal oblong shape provided on the heat shield plate 9 on the diagonal lines I and I '. Inside the two fitting holes 9a of
The two mounting portions 8a having substantially L-shaped side surfaces having the
While protruding below the heat shield plate 9 inside, the two mounting portions 8a, 8a provided on the cylinder housing portion 4 side project into the cylinder housing portion 4 on one side of the stove body 1 ( (See FIG. 3).

As described above, when the cassette stove is not used, the two mounting portions 8a of the Gotoku 8 are accommodated in the case 2 in the inverted state. It is more compact and more compact than a cassette stove. For this reason, for example, in the case of camping, hiking, etc., the cassette stove can be easily transported and stored without taking up a lot of space and can be handled easily. Moreover, the tops of the burner 6 and the Gotoku 8 are soup saucers 7
Foreign matter such as dust will not enter the cassette stove.

Further, the cassette cylinder A is stored in the regular position in the cylinder storage 4 by being obstructed by the two mounting portions 8a, 8a protruding inward from the fitting holes 9a provided in the heat shield plate 9. Can not be set. As a result,
Even if the dial knob 3 is accidentally rotated by mistake, the risk that flammable gas is supplied from the cassette cylinder A to the cylinder and leaks out, or the flammable gas is ignited and suddenly ignites is prevented. .

When using the cassette stove, first, the Gotoku 8 which is inverted and placed on the upper surface of the case 2 when not in use or during storage is pulled out of the placing portion 8a from the fitting hole 9a. As a result, the soup tray 7 and the Gotoku 8 are placed upright and placed on the upper surface of the case 2 for use (see FIG. 4). Then, by storing the cassette cylinder A in the cassette storage portion 4 of the case 2, the cassette cylinder A is set to the regular position and is ready for use.

Further, since the heat shield plate 9 is provided between the juice receiving tray 7 and the cassette housing portion 4, the heat shield plate 9 reflects or blocks the heat from the burner 6. The cassette cylinder A is prevented from being directly heated.

At this time, the installation distance of the cassette cylinder A housed in the cassette housing section 4 is closer to the burner 6 than before, but the heat radiated from the burner 6 is blocked by the heat shield plate 9. As a result, most of it is prevented from being directly transmitted to the cassette cylinder A, so that the cassette cylinder A is prevented from exploding due to high temperature, which is safe. However, in the cassette cylinder A, the combustion gas enclosed in the cassette cylinder A is warmed to some extent by being heated by the heat from the burner 6 to heat the combustion gas in the cassette cylinder A. However, due to the latent heat of vaporization that occurs when the gas is supplied into the burner 6 via the governor 5, the cassette cylinder A itself is cooled, and the amount of combustion gas supplied to the burner 6 is reduced, and there is no inconvenience that the thermal power is reduced. A quantity of combustion gas can be supplied.

In the drawing, when the cassette stove 1 is not used, the juice tray 7 and the Gotoku 8 are turned over so that two of the four mounting portions 8a are fitted to the heat shield plate 9 by two fittings. Although it is fitted in the hole 9a, the mounting portion 8a of the Gotoku 8 is not limited to the shape shown in the figure, and the number of the mounting portions may be three or more, and the mounting portion 8a can be inserted. Fitting holes 9a for projecting the same can be provided in the number corresponding to the position corresponding to the mounting portion 8a. Moreover, by adjusting the height h of the mounting portion 8a of the Gotoku 8 it is possible to adjust the protrusion degree according to the set position of the cassette cylinder A stored in the cassette storage portion 4.

[0021]

As described above, according to the present invention, since the hob itself is small and compact, it is easy to carry, and it does not take up any space during use or storage. Moreover, even if the dial knob is misoperated, combustible gas does not leak from the burner, and the safety is high. Moreover, unlike the conventional case, it is not necessary to provide a special safety device, so that the structure of the cassette stove itself is simplified and the manufacturing cost is reduced.
