Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a combustion cylinder structure of an oil stove, and is particularly suitable for outdoor use such as camping.

[0002]

[Prior Art]

 Since the stove used for outdoor camping requires wind resistance, even if liquid fuel is used, the fuel is pressurized and sent to a high temperature part to produce vaporized gas, and a gas cylinder such as LPG is used. Like the ones used, those that burn with a gas burner are common, and those that use a double-cylinder combustion cylinder, such as a petroleum hob for home use, have not been commercialized.

[0003]

[Problems to be solved by the device]

 The conventional technology described above, which gasifies and burns liquid fuel, has the drawback that the manufacturing cost is high because the vaporization part and the like require structural accuracy, and the selling price is also high for the amount of combustion. ..

Therefore, if a petroleum hob using a core with a proven track record for household use is used, the amount of combustion is large because of its cost, but it is preferable if the effect of wind is taken into consideration when it is used outdoors. Of course, currently available oil stoves can only be used in tents where the conditions are almost the same as at home.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, in this invention, the combustion core 3 is seen in the lower part of the gap between the inner flame cylinder 1 and the outer flame cylinder 2, and the outer cylinder 4 is concentrically arranged outside the inner and outer flame cylinders 1 and 2. In the provided combustion cylinder, the core outer cylinder 5 provided outside the combustion core 3 is provided with a large diameter portion 5a having an enlarged diameter, and the large diameter portion of the core outer cylinder 5 is provided from the lower edge portion of the outer cylinder 4. A porous inner windshield 6 is hung toward 5a, and a porous outer side connected to the outer cylinder 4 and the inner windshield 6 on the large-diameter portion 5a of the core outer cylinder 5 with a gap. A windshield plate 7 is provided, and an outer cylinder top plate 8 provided at the upper edge of the outer cylinder 4 is extended outward from the upper portion of the outer windshield plate 7, and a handle 9 is attached to the outer cylinder top plate 8. is there.

Further, each of the inner windshield 6 and the outer windshield 7 is provided with one ignition hole 6a for inserting an ignition tool into the combustion wick 3, and each of the outer windshield 7 has an ignition hole 7a. 3 is opened at approximately the same height as the upper end, and the ignition hole 6a of the inner windshield 6 is shifted downward from the ignition hole 7a of the outer windshield 7 to facilitate insertion of the igniter. is there.

[0007]

[Action]

 In the multi-cylinder combustion cylinder, the fuel vaporized from the combustion wick 3 is combusting in the space between the inner and outer flame cylinders 6a and 7a, and the combustion air enters from the lower space between the outer cylinder 4 and the outer flame cylinder 4. Used for combustion.

In this invention, a porous inner windshield 6 is hung from the lower edge of the outer casing 4 toward the large-diameter portion 5 a of the core outer casing 5. Since the porous outer windshield 7 connected to the large-diameter portion 5a of the core outer cylinder 5 through the gap is provided, when wind blows on the combustion cylinder, the outer windshield 7a and the inner windshield 6a are doubled. The air is now supplied through the windshield, and the combustibility is improved.

Further, when the handle 9 is lifted, the outer cylinder top plate 8, the outer cylinder 4, the inner flame cylinder 1, and the outer flame cylinder 2 other than the outer windshield 7 are lifted up on the handle 9 side, so that the ignition holes of the inner windshield 6 are ignited. 6a and the ignition hole 3 of the outer windshield 7 can be aligned at substantially the same position, and the combustion wick 3 is exposed through the two ignition holes 6a and 7a. It is possible to ignite by approaching the combustion wick 3 through the a. After that, when the handle 9 is returned and the inner and outer flame cylinders 6a and 7a are returned, air is sucked from the inner and outer flame cylinders 6a and 7a to continue combustion.

Embodiments Next, the structure will be described with reference to the drawings showing an embodiment. 1 is an inner flame cylinder having a large number of ventilation holes, 2 is an outer flame cylinder having a large number of ventilation holes, and 3 is an inner / outer flame cylinder 1.・ The combustion wicks 4, which are seen in the lower part of the gap of 2, are outer cylinders provided outside the outer flame cylinder 2 with a gap, and generally have no holes, and the inner and outer flame cylinders 1 and 2 The outer cylinder 4 and the outer cylinder 4 are integrally held by a cross pin 10 to form a combustion cylinder.

Reference numeral 5 denotes a core outer cylinder provided in contact with the outside of the combustion core 3 and forming a large diameter portion 5 a having a diameter enlarged in the middle of the core outer cylinder 5, and the large diameter portion 5 a Inside, a core up-and-down mechanism 11 is installed. 6 is a porous inner windshield that hangs from the lower edge of the non-perforated outer cylinder 4 toward the large diameter portion 5a of the core outer cylinder 5, and 7 is a gap outside the outer cylinder 4 and the inner windshield 6. The outer windshield is a porous outer windshield provided upright from the large diameter portion 5a of the outer core tube 5. Then, the wind blown to the combustion cylinder is controlled by the outer windshield 7 and the inner windshield 6.

Reference numeral 6a denotes a lower portion of the inner windshield plate 6, which is an ignition hole opened below the upper end of the combustion wick 3, and has a diameter of 8 to 10 mm in the embodiment. Further, 7a is a lower portion of the outer windshield 7, which is an ignition hole opened at substantially the same height as the upper end of the combustion wick 3, and is constituted by a hole having a diameter of 10 to 15 mm in the embodiment.

Reference numeral 8 denotes an outer cylinder top plate provided outwardly from the upper edge of the outer cylinder 4 in a brim shape. The outer edge of the outer cylinder top plate 8 is extended outward while being close to the upper end of the outer windshield 7. There is. Reference numeral 9 is a handle integrally attached to the outer cylinder top plate 8 and is used for rotating and lifting the combustion cylinder. Reference numeral 13 denotes an inner core cylinder that contacts the inside of the combustion core 3, and the combustion core 3 is sandwiched between the outer core cylinder 5 and the inner core cylinder 12. Reference numeral 13 denotes a core up / down knob for operating the core up / down device 11.

As described above, not only are the positions of the ignition holes 6a and 7a displaced relative to the height of the combustion wick 3, but also when the handle 9 is positioned in the front when using a through-hole, If the ignition hole 6a of the inner windshield 6 is not located directly below the ignition hole 7a of the windshield 7 and the two ignition holes 6a and 7a are aligned only when the handle 9 is lifted while rotating, the two The distance between the ignition holes 6a and 7a is further increased, and the influence of wind can be reliably prevented.

[0015]

[Effect of the device]

 Since the present invention has the above-described structure and operation, the inner windshield 6 and the outer windshield 7 do not cause a flame to rise or smoke due to the wind blown to the combustion cylinder.

Further, since the inner and outer windshields 6 and 7 are both porous, the air supplied to the combustion cylinder is rectified and sent, so that good combustion can be performed.

Further, since the inner and outer windshield plates 6 and 7 are provided with large-diameter ignition holes 6a and 7a, respectively, even if the windshield measures are taken, the ignition holes 6a and 7a will be opened when the handle 9 is operated. They are in communication with each other and can be easily ignited by a match or the like.

Further, since the position of the ignition hole 6a7a is provided so as to be displaced with respect to the height of the combustion wick 3, even if the ignition holes 6a and 7a have a large diameter, the wind does not pass straight into the combustion cylinder, The effect of wind caused by the ignition holes 6a and 7a can be prevented.
