Accordingly, the size of the main body portion is excessively large, causing inconvenience in carrying the gas stove, but the portable gas stove 1000 of the present invention is heat-blocking by the heat insulating portion 400 installed in the main body portion 100, which will be described later. Possibly, by inserting the gas container 1 under the stove 300, that is, in the center of the main body 100, the area of the main body 100 is formed to have a size similar to that of the stove 300. can do. Therefore, since the body portion 100 and the stove portion 300 are vertically stacked, the size of the body portion 100 can be minimized to increase the portability of the portable gas stove 1000 .

In addition, the body portion 100 is provided in the insertion hole H of the body portion 100 to protect the gas container 1 protruding out of the body portion 100 after being accommodated in the accommodation space A1. It may include a gas container cover 110 formed in a cylindrical shape with one side open and coupled to accommodate the other part of the gas container 1 .

For example, the gas container cover 110 may be formed in a cylindrical shape with one side open, and a plurality of coupling protrusions 111 may be formed at an open end. Accordingly, the gas container cover 110 may be rotated and coupled to the insertion hole H of the main body 100 to be coupled and fixed to the main body 100 by engaging the plurality of coupling protrusions 111 .

In addition, the cover part 200 is formed in an upwardly concave bowl shape in which a lower part is opened and at least a part of the upper surface is formed flat, so that the open upper part of the main body part 100 can be closed.

For example, the cover part 200 has a bowl shape that is recessed in the opposite direction to the body part 100, and the open lower part is formed in a shape corresponding to the open upper part of the body part 100, so that the body part 100 ) When seated on the upper end of the main body portion 100, the open top of the body portion 100 can be completely closed.

In addition, the cover part 200 is formed of a metal material so that the stove part 300, which will be described later, is easily supported on the flat part of the upper surface and is not easily deformed by the heat of the stove part 300. Similar to the body portion 100, a plurality of through-holes may be formed in the side wall to discharge heat inside the heat insulation space A2 to the outside.

As shown in FIGS. 1 to 5 , the stove unit 300 is installed on a flat portion of the upper surface of the cover unit 200 and burns fuel supplied from the gas container 1 accommodated in the body unit 100. and the heat generated during combustion can be released to the outside.

More specifically, as shown in FIGS. 5 and 6, the stove unit 300 is installed on the upper surface of the blocking member 420 included in the heat insulating unit 400 to be described later, and accommodated in the accommodation space A1. The venturi member 310, which diffuses the fuel supplied from the gas container 1 upward by the venturi structure, and at least a part of the upper portion penetrates the cover part 200 and protrudes upward from the cover part 200. A combustion unit 320 installed on the upper side of the venturi member 310 to generate a flame by burning the fuel diffused through the venturi member 310, and an "L" character installed in the combustion unit 320. It is installed to be located on one side of the combustion unit 320 by the bracket 331 of the form, the ignition unit 330 for igniting the fuel and the cover unit 200 to be located on the upper side of the combustion unit 320 It may include a heat dissipation unit 340 installed on the upper surface and formed in a double cylindrical structure to store and dissipate heat generated by the flame generated in the combustion unit 320 .

For example, the venturi member 310 of the stove unit 300 is formed in a shape in which the cross-sectional area gradually narrows upward, and the combustion unit 320 coupled to the upper side of the venturi member 310 is a venturi member 310 It may be formed to have a larger cross-sectional area than the largest cross-sectional area of the part.

Accordingly, the gas introduced from the gas container 1 through the gas connection pipe (not shown) to the lower end of the venturi member 310 moves upward where the combustion unit 320 is installed, causing a venturi effect to burn the gas. The gas entering the unit 320 may spread evenly while being diffused in the combustion unit 320 . At this time, the ignition unit 330 installed on one side of the combustion unit 320 ignites the initial flame, so that the combustion unit 320 is ignited by the gas and causes a flame to occur.

In addition, as shown in FIGS. 5 and 6, the heat dissipation unit 340 installed above the combustion unit 320 to store and dissipate heat generated by the flame generated in the combustion unit 320 has a first diameter A first body 341 formed in a cylindrical shape with upper and lower portions open to receive heat from the flame of the combustion unit 320 and store heat, and an upper portion having a second diameter larger than the first diameter, and The second body 342 and the combustion unit 320 are formed in a cylindrical shape with an open bottom to surround the first body 341 and release heat stored by the first body 341 to the outside. The first body 341 and the second body are installed on the upper part of the first body 341 and the second body 342 so that the heat generated by the flame is not released into the atmosphere and can be stored in the first body 341. A cover 343 closing the open top of 342 may be included.

For example, the first body 341 may be installed to be positioned above the combustion unit 320 by the support bracket 344 installed on the upper surface of the cover unit 200 . Accordingly, the first body 341 can receive and store heat from the flame of the combustion unit 320 through the open lower part, and the upper part opened by the cover 343 is closed to store the stored heat. may be blocked from being discharged to the outside through the open top. At this time, a plurality of heat storage holes 341a having a circular shape are formed on the outer circumferential surface of the first body 341, so that more heat conduction from the combustion unit 320 can be stored.

Also, the second body 342 may be installed to be positioned above the combustion unit 320 while surrounding the first body 341 by the support bracket 344 . In addition, the second body 342 may have a plurality of heat dissipation holes 342a having a slot hole shape along the outer circumferential surface so as to release heat stored in the first body 341 to the outside. there is.

Therefore, the first body 341 receiving heat from the flame of the combustion unit 320 is heated and maintained at a high temperature, and in particular, a plurality of heat storage holes 341a formed along the outer circumferential surface of the first body 341. ), the heat can be accumulated, so a higher temperature can be maintained.

In this way, the heat stored in the first body 341 is discharged to the side of the heat radiating part 340 through the plurality of heat radiating holes 342a formed along the outer circumferential surface of the second body 342, so that the portable gas stove ( 1000), it is possible to perform heating by evenly transferring heat to all users located around. At this time, since the main purpose of the plurality of heat radiation holes 342a formed in the second body 342 is to radiate heat, the plurality of heat storage holes 341a of the first body 341 formed for the purpose of storing heat It may be desirable to form a larger size.

In addition, the open tops of the first body 341 and the second body 342 of the heat dissipation unit 340 are closed by the above-described cover 343 to reduce the release of heat upward to some extent, but , Since it is impossible for the cover 343 to completely block the heat, the heat emitted to the top of the first body 341 and the second body 342 must exist without spreading to the side of the heat dissipation unit 340. .

Accordingly, the stove unit 300 of the portable gas stove 1000 of the present invention includes a rotating fan 351 and is installed on the upper side of the heat dissipating unit 340, and the rotating fan 351 rotates the heat dissipating unit. A heat spreader 350 may further include a heat dissipation unit 350 that diffuses heat dissipated upward from the 340 to a side of the heat dissipation unit 340 .

For example, the heat diffusion unit 350 is formed in a circular cap shape and coupled to the upper side of the cover 343, and a heat dissipation bracket 352 having a plurality of heat dissipation holes formed on the upper surface, and the heat dissipation bracket 352 It may include a rotating shaft 353 installed at the center of the rotating shaft 353 and a rotating fan 351 rotatably installed on the rotating shaft 353 and rotating by hot air rising through the heat dissipating bracket 352.

More specifically, the rotating fan 351 is a fan capable of converting and spreading the direction of the rising heat while rotating by the heat rising through the heat dissipating bracket 352 to the side of the heat dissipating unit 340, It may be a propeller-type impeller having a streamlined airfoil-shaped helical rotary blade.

In addition, in the stove unit 300, a plurality of wires are formed on the upper surface of the cover unit 200 to surround the heat dissipation unit 340 so as to prevent a user from being injured by directly contacting the heat dissipation unit 340. A protective grill 360 and a cap 370 installed on the top of the protective grill 360 to block the heat dissipation of the heat dissipation part 340 upward, and the user can easily use the portable gas stove 1000 It is formed in an arc shape to selectively block heat transmitted to the side of the handle 380 and the heat dissipation part 340 installed on the cap part 370 so as to be movable, and can be attached to or detached from the protective grill 360 at any position. It may further include a heat blocking plate 390 that is installed in such a way.

At this time, the cap part 370 can guide the direction of diffusion of the hot air by the rotation of the rotating fan 351 installed in the heat spreading part 350 to the side of the heat dissipating part 340, so that the heat on the lower surface of the cap part 370 A diffusion member 371 formed in a dome shape may be installed at a position corresponding to the diffusion part 350 .

In this way, the diffusion member 371 of the cap portion 370 is formed in a dome shape to surround the rotation fan 351 on the upper side of the rotation fan 351 of the heat diffusion portion 350, and the heat dissipation portion 350 It may have an effect of further activating the action of the rotating fan 351 that spreads the heat rising upward to the side of the stove 300 by rotation.

In addition, as shown in FIGS. 7 and 8 , the heat insulator 400 maintains the heat of vaporization required to vaporize the liquefied gas inside the gas container 1 accommodated in the accommodating space A1 of the main body 100. It is installed in the internal space (A) of the body part 100 to block direct transfer of heat generated in the stove part 300 to the gas container 1, and to set the temperature of the gas container 1 above. It can be maintained at a temperature higher than the vaporization temperature of the liquefied gas.

For example, the liquefied gas contained in the gas container 1 may be vaporized inside the gas container 1 and then discharged to the outside of the gas container 1 . At this time, when the heat required for vaporization of the liquefied gas is absorbed by the gas container 1, the temperature of the gas container 1 gradually decreases due to an endothermic reaction, and dew is formed on the outer surface of the gas container 1 due to the difference from the external temperature. Condensation and the like may occur.

As such, heat of vaporization is required for vaporization of the liquefied gas. When using a gas stove, the above-described endothermic reaction continues to occur according to the consumption of gas, and the temperature of the gas container 1 gradually decreases, and the gas container 1 ) As the temperature decreases, the vaporization of the liquefied gas inside the gas container 1 is not sufficiently provided, and the gas pressure decreases, causing a problem in that firearms become weak. Such a phenomenon may be more severe when a gas stove is used outside in winter when the temperature is low.

However, the portable gas stove 1000 of the present invention can easily solve the above problems due to the heat insulation unit 400 installed in the body unit 100.

For example, as shown in FIGS. 7 and 8 , the heat insulator 400 is installed inside the main body 100 to protect the internal space A of the main body 100 from at least a portion of the gas container 1. The heat insulating member 410 divided into a receiving space (A1) for accommodating the gas container (1) and a heat insulating space (A2) for keeping the gas container 1 warm, and installed in the heat insulating space (A2) inside the main body, in the stove unit 300 A blocking member 420 that blocks the direct transfer of generated heat toward the gas container 1 and a heat insulating member 410 inside the main body 100 are formed to pass through, and one end is formed in the heat insulating space A2. is connected to the blocking member 420, and at least a portion of the other end is formed to surround at least a portion of the gas container 1 in the accommodating space A1, and the blocking member heated by the heat generated from the stove 300 ( It may include a heat transfer member 430 that transfers some of the heat of the gas container 1 (420).

More specifically, the heat insulating member 410 is supported at a predetermined height by a plurality of support bosses 120 formed on the flat bottom surface of the body portion 100 in the internal space A of the body portion 100, The inner space (A) of the body portion 100 may be divided into an accommodation space (A1) and an insulation space (A2).

In addition, the middle portion of the heat insulating member 410 includes an arc portion 411 formed in an arc shape spaced apart by a predetermined distance along the outer circumferential surface of the gas container 1, and the gas container 1 inserted into the body portion 100. As at least a portion of the outer circumferential surface of the gas container 1 is surrounded by the circular arc portion 411 at a predetermined distance apart, the gas container 1 may have a warming effect.

In addition, the blocking member 420 is supported by a plurality of support bosses 412 formed on the upper surface of the arc portion 411 of the heat insulating member 410, and is positioned in the heat insulating space A2 of the body portion 100. can For example, the blocking member 420 is formed in the shape of a plate having an outwardly inclined wall portion, and is positioned above the gas container 1 kept warm by the heat insulating member 410 to prevent the hearth portion 300 from being heated. It is possible to prevent heat from being directly transmitted to the gas container 1, thereby preventing an explosion due to excessive heating of the gas container 1.

The blocking member 420 has an area that can sufficiently cover the gas container 1 inserted into the main body 100 so as to effectively block the heat of the stove 300 transmitted to the gas container 1. For ventilation of the heat insulating space A2 of the main body 100, it may be formed with a smaller cross-sectional area than the cross-sectional area of the heat insulating space A2.

In addition, the above-described heat insulation member 410 is preferably formed of a synthetic resin material for the main purpose of keeping the gas container 1 warm at an appropriate temperature, and the blocking member 420 directly into the gas container 1 It may be preferable to be formed of a metal material for the main purpose of blocking the heat of the stove unit 300 that is transmitted.

In addition, the heat transfer member 430 may be formed in an “L” shape as a whole including the vertical portion 431 and the horizontal portion 432, and the vertical portion 431 may be formed to pass through the heat insulating member 410. there is.

For example, in the heat transfer member 430, an end portion of a vertical portion 431 penetrating the heat insulating member 410 and located in the heat insulating space A2 of the body portion 100 is coupled to the lower surface of the blocking member 420, and is accommodated. The horizontal portion 432 located in the space A1 may support at least a portion of the gas container 1 inserted into the body portion 100 . At this time, at least a portion of the horizontal portion 432 is formed in an arc shape to surround the outer circumferential surface of the gas container 1 to increase the contact area with the gas container 1, thereby smoothly inducing heat transfer to the gas container 1. can do.

Accordingly, some of the heated heat of the blocking member 420 is transferred to the horizontal portion 432 through the vertical portion 431 of the heat transfer member 430 while blocking the downward heat generated in the stove portion 300, The gas container 1 in contact with the horizontal portion 432 can be appropriately heated.

In this way, the gas container 1 inserted into the body portion 100 is prevented from being excessively heated by the heat of the stove portion 300 by the heat insulating portion 400, while the liquefied gas contained therein is vaporized. By appropriately supplying the required heat of vaporization, it is possible to prevent the liquefied gas from being excessively cooled due to an endothermic reaction caused by the vaporization of the liquefied gas, thereby reducing the vaporization of the liquefied gas.

Therefore, according to the portable gas stove 1000 according to an embodiment of the present invention, the gas container 1 inserted into the main body 100 and the stove 300 have a straight structure in the vertical direction, thereby providing a portable gas Since the structure of the stove 1000 is formed compactly, it is easy to carry, and it may have an effect of reducing a required area for installation of the portable gas stove 1000.

In addition, the portable gas stove 1000 includes a heat diffusion unit 350 that diffuses heat dissipated upward to the side of the heat dissipation unit 340 by using a rotating fan 351 on the top of the stove unit 300. Heating efficiency can be increased by diffusing the flame of the sideways.

In addition, by providing appropriate heat of vaporization to the gas container 1 and keeping it warm through the heat insulator 400 installed in the main body 100, evaporation of the liquefied gas occurs actively in the gas container 1, It may have the effect of preventing the gas pressure from falling and thus preventing the firearm from weakening.
