1. Field of the Disclosure
The present disclosure relates to a burner, and particularly, to a hose burner having a folding type supporting leg capable of being easily stored by having a reduced entire size through transformation.
2. Background of the Disclosure
The conventional portable burner, which has been used in the outdoor field for cooking, etc., may be classified into a gas burner and an oil burner. The oil burner has complicated setting procedures, and causes a novice to use it with a difficulty. As the oil burner should be preheated by alcohol, etc., a user's portability is lowered, a preheating process is inconvenient, etc. Further, if the oil burner is preheated at an improper time, soot is generated to block a nozzle. This may cause a user to clean the nozzle after cooling the oil burner, and then to preheat the oil burner again.
Further, as flame is controlled by an air valve, it is difficult to properly control the flame. If there remains a pressure inside an oil container, oil is emitted to outside. Accordingly, upon completion of usage of the oil bur, air should be discharged. Further, the oil burner should be compressed whenever it is used.
On the other hand, the gas burner may have the following disadvantages despite its simple usage.
Firstly, the gas burner is expensive, and uses butane gas having small calories, etc. Accordingly, a user should prepare a container filled with a large amount of gas during a long travel. Secondly, a one-time container should be abandoned after it is used one time. This may lower an economic characteristic, and may cause a user not to carry the gas burner during a long travel.
In order to solve such problems, a burner, which can be used simply and enhance a user's portability by having a minimized entire size through transformation after usage, is required in recent years.
SUMMARY OF THE DISCLOSURETherefore, an aspect of the detailed description is to provide a hose burner having a folding type supporting leg, capable of being used through simple manipulations and enhancing a user's portability by having a minimized entire size through transformation after usage.

The accompanying drawings, which are included to provide a further understanding of the disclosure and are incorporated in and constitute a part of this specification, illustrate exemplary embodiments and together with the description serve to explain the principles of the disclosure.
In the drawings:
Description will now be given in detail of the exemplary embodiments, with reference to the accompanying drawings. For the sake of brief description with reference to the drawings, the same or equivalent components will be provided with the same reference numbers, and description thereof will not be repeated.
Hereinafter, a hose burner having a folding type supporting leg according to an embodiment of the present invention will be explained in more detail with reference to the attached drawings.
As shown, the hose burner having a folding type supporting leg according to an embodiment of the present invention comprises: a body unit 100 including a cylindrical body 110 having an open upper surface and having an insertion opening 111 penetratingly-formed at one side thereof, and including an air mixture container 120 having a mixture pipe 123, the air mixture container 120 accommodated in the body 110 and configured to mix injected fuel and air to combust the fuel; a fuel supply pipe 200 having a fuel supply opening 210 at one end thereof, bent to pass through an upper surface of the body unit 100, and having a fuel injection nozzle 220 at another end thereof, the fuel supply opening 210 inserted into the insertion opening 111 of the body 110 and protruding toward the mixture pipe 123; and a folding type supporting leg 400 configured to support the body unit 100 installed with a predetermined gap from an installation surface, the folding type supporting leg 400 rotatably provided at the body unit 100 so as to overlap the fuel supply pipe 200, and foldably installed so as to enclose an upper surface and a lower surface of the body unit 100.
Preferably, the body unit 100, a member for providing heat to an object by igniting flame when using the hose burner, is configured to provide a user's desired amount of heat to an object by supplied fuel.
As aforementioned, the body unit 100 is composed of a body 110 which forms the appearance of the body unit 100, and an air mixture container 120 accommodated in the body 110.
The body 110 is provided with the insertion opening 111 penetratingly-formed at one side thereof, the insertion opening 111 configured to insert the fuel supply opening 210 thereinto to thus protrude the fuel supply opening 210 toward inside of the body 110. The body 110 has an open upper surface, and has a predetermined inner space for accommodating the air mixture container 120.
A bottom surface of the body 110 is formed to protrude in a wedge shape, and a body supporting member 310 of the supporting unit 300 to be explained later is rotatably coupled to a circumference of the bottom surface outward-protruding in a convexed manner.
Mounting grooves 112 configured to mount the air mixture container 120 when the air mixture container 120 is accommodated in the body 110, are concaved from upper regions of a plate surface in a facing manner.
The air mixture container 120 accommodated in the body 110 is a member configured to mix supplied fuel with external air so that the fuel can be completely combusted for prevention of exhaust gas. The air mixture container 120 has the same cylindrical shape as the body 110.
The air mixture container 120 is provided with a mixture pipe 123 through which external air is introduced to be supplied when fuel is combusted. The mixture pipe 123 allows external air to be mixed with fuel for complete combustion of the fuel, thereby preventing occurrence of exhaust gas.
The air mixture container 120 may include a ring-shaped outer container 121 having a predetermined diameter and a predetermined height, and formed to contact an inner surface of the body 110; an inner container 122 having a smaller diameter than the outer container 121, spaced from the outer container 121, and forming a space where the fuel is discharged; and a fuel discharge portion 124 formed between the outer container 121 and the inner container 122, and configured to discharge fuel.
The outer container 121 is a ring-shaped member having an open upper surface and formed to have a predetermined height. The outer container 121 has a diameter large enough to contact an inner wall surface of the body 110, thereby being accommodated in the body 110.
Mounting protrusions 121a, which are inserted into the mounting grooves 112, are protruding from upper regions of the outer container 121 facing each other with a constant interval therebetween, so that the outer container 121 can be mounted at the mounting grooves 112 of the body 110 when the outer container 121 is accommodated in the body 110.
The inner container 122 is formed to have a smaller diameter than the outer container 121, and is provided in the outer container 121 with a spacing distance from the outer container 121. Due to the spacing distance between the outer container 121 and the inner container 122, flame is combusted by the fuel discharge portion 124 formed at the spacing distance.
The air supply cut-out surface 125, configured to supply external air into the air mixture container 120, may be formed at a plate surface of each of the outer container 121 and the inner container 122 where the fuel supply opening 210 is disposed when the air mixture container 120 is accommodated in the body 110.
More specifically, the air supply cut-out surface 125 is provided at a plate surface of each of the outer container 121 and the inner container 122 facing each other.
An outer surface 123a is formed to enclose a circumference of the air supply cut-out surface 125 formed at the outer container 121, and to enclose a circumference of the air supply cut-out surface 125 formed at the inner container 122. Under such configuration, the mixture pipe 123 is formed.
Preferably, a bottom surface of the mixture pipe 123 is formed to be inclined toward the fuel supply opening 210. The reason is in order to prevent fuel supplied from the fuel supply portion 210, from being provided to the fuel discharge portion 124 temporarily and excessively.
A burner cap 130, which has a plurality of slits 131 penetratingly-formed in a circumferential direction of the air mixture container 120 such that flame generated when the fuel is combusted is uniformly arranged along a circumference of the air mixture container 120, may be mounted to an upper surface of the air mixture container 120.
The burner cap 130 is installed at an upper surface of a space between the outer container 121 and the inner container 122, thereby guiding flame generated by fuel supplied toward the fuel discharge portion 124 to be uniformly ignited along the upper surface of the space.
A shielding cover 140, configured to shield part of an upper surface of the mixture pipe 123 from outside for prevention of excessive mixture between the fuel and air, may be provided at an upper surface of the air mixture container 120 between the air mixture container 120 and the burner cap 130.
The shielding cover 140 may include a ring-shaped member 141 having a predetermined area and configured to shield part of an upper surface of the fuel discharge portion 124 in a horizontal direction; and a protruding member 142 protruding from an inner surface of the ring-shaped member 141 by a predetermined length in a height direction, and disposed to be spaced from a circumferential surface of the inner container 122.
Under such configuration, external air is introduced into the mixture pipe 123 through the gap between the inner container 122 and the protruding member 142, and is mixed with fuel. Accordingly, excessive mixture between air and fuel can be prevented by the shielding cover 140.
The fuel supply opening 210 to be inserted into the insertion opening 111 of the body 110 is provided at one end of the fuel supply pipe 200. The fuel injection nozzle 220, connected to the extended pipe 510 and configured to inject fuel from the fuel box 500 to the fuel supply pipe 200, is formed at another end of the fuel supply pipe 200.
The fuel injection nozzle 220 is rotatably coupled to another end of the fuel supply pipe 200 without being protruded toward outside of the hose burner when the hose burner is in a stored status or a carried status. The fuel injection nozzle 220 is rotated so that its protruded region can be toward the body unit 100 when the hose burner is in a stored status or a carried status.
Preferably, the fuel supply pipe 200 is bent so as to pass through an upper surface of the body unit 100, so that the hose burner can be automatically preheated without an additional manipulation for preheating.
The folding type supporting leg 300 includes a plurality of body supporting members 310 extending from a bottom surface of the body unit 100 by a predetermined length in a diameter direction of the body unit 100, and rotatably coupled to the body unit 100; and a plurality of supporting legs 320 rotatably provided at end portions of the body supporting members 310, mounted to an installation surface, and configured to support the body unit 100.
Preferably, the body supporting members 310 are rotatably coupled to a bottom surface of the body unit 100 in a state where some regions thereof overlap each other, so that the hose burner having a folding type supporting leg can be easily stored with a decreased volume as the plurality of supporting legs 320 are assembled together to one side.
A stopper 311, which contacts one side surface of a neighboring body supporting member 310, may be provided on one side surface of the overlapped regions, so that a rotation angle of the body supporting members 310 can be restricted.
Preferably, the stoppers 311 are provided on one side surface of the body supporting members 310 where the supporting legs 320 are spaced from each other with the same interval when the body unit 310 is installed. Under such configuration, the supporting legs 320 are radially widened with an angle of 120°, so that the body unit 100 can be stably supported.
Preferably, the supporting legs 320 are rotatably coupled to one side of the body supporting members 310, so that the hose burner having a folding type supporting leg can have a decreased volume for storage.
The supporting legs 320 are bent to have a ‘’ shape, so as to enclose an outer surface of the body unit 100 of the hose burner, when the hose burner having a folding type supporting leg is stored. Restriction protrusions 321, which contact one side of extended members 410 to be explained later, are provided on one plate surface of the supporting legs 320, so as to maintain a supported status of the body unit 100 by restricting a rotation angle of the supporting legs 320 when the supporting legs 320 are folded from the body supporting members 310.
Extended members 410, upward extending by a predetermined length in a height direction of the body unit 100, are fixedly-coupled to one side of the body supporting members 310 to which the supporting legs 320 are rotatably coupled.
Heating object supporting plates 400, configured to heat an object using the hose burner by mounting the object on the body unit 100, is rotatably coupled to the end of the extended members 410.
Preferably, the heating object supporting plates 400 are configured as three members radially widened by 120° so that a heating object mounted thereon can be stably supported, like the body supporting members 310.
Like the supporting legs 320, the heating object supporting plates 400 are preferably rotatably coupled to the end of the extended members 410 so that the hose burner having a folding type supporting leg can have a decreased entire size when stored without being used.
Supporting protrusions 411, configured to support the object to be heated when the object to be heated is mounted on the heating object supporting plates 400, may be protruded from one side of the extended members 410. Inserting grooves 401, configured to insert the supporting protrusions 411 therein, may be concaved from one side of the heating object supporting plates 400.
A method for using the hose burner having a folding type supporting leg according to an embodiment of the present invention will be explained as follows.
Firstly, the plurality of body supporting members 310 are rotated so as to be radially disposed by being widened at 120°, thereby making the supporting legs 320 spaced from each other.
A maximum widening angle of the body supporting members 310 is limited to 120° due to the stoppers 311 formed at one side of the body supporting members 310 overlapped one another. Accordingly, once a user rotates the body supporting members 310 to a maximum angle, the body supporting members 310 are automatically widened by 120°.
Once the supporting legs 320 are rotated to a maximum angle, the restriction protrusions 321 provided at one plate surface of the supporting legs 320 come in contact with one side of the extended members 410. As a result, the supporting legs 320 are in a status to support the body unit 100, without being rotated any longer.
Then, the heating object supporting plates 400, rotatably coupled to the end of the extended members 410, are widened by being outward rotated from the center of the hose burner. As a result, the inserting grooves 401 are inserted into the supporting protrusions 411 to thus be supported. Accordingly, an object to be heated can be stably mounted to the heating object supporting plates 400.
Then, the end of the extended pipe 510, to which the fuel container 500 has been connected, is fitted into the fuel injection nozzle 220 for communication. As a result, fuel inside the fuel container 500 is supplied through the fuel supply opening 210, and the supplied fuel is mixed with air at the mixture pipe 123 of the air mixture container 120.
In case of initial ignition using a match, a lighter, etc., the fuel mixed with air is combusted, and the fuel which passes through inside of the fuel supply opening 210 which passes through an upper surface of the body unit 100 is vaporized. As the vaporized fuel is continuously supplied through the fuel supply opening 210, heat is supplied to an object to be heated for cooking.
After the hose burner having a folding type supporting leg is used up, the body supporting members 310 of the supporting unit 300 are rotated so that the plurality of supporting legs 320 can be assembled one another. Then, the supporting legs 320 and the heating object supporting plates 400 are folded to enclose an outer surface of the body unit 100. And the fuel injection nozzle 220 rotatably provided at another side of the fuel supply pipe 200 is rotated toward the body unit 100, so that the hose burner can be stored or carried with a minimized size.
The foregoing embodiments and advantages are merely exemplary and are not to be considered as limiting the present disclosure. The present teachings can be readily applied to other types of apparatuses. This description is intended to be illustrative, and not to limit the scope of the claims. Many alternatives, modifications, and variations will be apparent to those skilled in the art. The features, structures, methods, and other characteristics of the exemplary embodiments described herein may be combined in various ways to obtain additional and/or alternative exemplary embodiments.
As the present features may be embodied in several forms without departing from the characteristics thereof, it should also be understood that the above-described embodiments are not limited by any of the details of the foregoing description, unless otherwise specified, but rather should be considered broadly within its scope as defined in the appended claims, and therefore all changes and modifications that fall within the metes and bounds of the claims, or equivalents of such metes and bounds are therefore intended to be embraced by the appended claims.
