The invention will be described in detail below by describing preferred embodiments of the invention with reference to the accompanying drawings. Identical reference numerals in each drawing indicate identical components.

[0030] FIG. 1 is a partially exploded perspective view of a multi-functional camping stove according to the first embodiment of the present invention.

[0031] As illustrated in FIG. 1, a multifunctional camping stove according to the first embodiment of the present invention may include a stove body (100) and a cooking section (210) for heat utilization.

[0032] As illustrated in FIG. 1, the stove body (100) is a general camping stove that generates heat through a predetermined means, and a separate description is omitted.

[0033] In the present invention, the heat utilization unit may include various devices and is coupled to the upper part of the stove body (100) to utilize the heat generated from the stove body (100) to provide various functions to the user. In the embodiment illustrated in FIG. 1, the heat utilization unit may include a cooking unit (210) coupled to the upper part of the stove body (100).

[0034] As shown in FIG. 1, the cooking unit (210) may be a device on which cooking tools such as a pan, a camping pot, or a wok are mounted on the top.

[0035] As shown in FIG. 1, a hole is formed through the center of the cooking section (210). The hole formed in the center of the cooking section (210) is intended to allow the flame or heat generated from the stove body (100) to be transferred to a cooking tool located at the top.

[0036] As shown in FIG. 1, a support may be formed on the upper surface of the cooking section (210) so that a cooking tool can be mounted at a certain distance apart. It is preferable to install at least three supports, but the shape and number of supports in the present invention are not limited to those shown in the drawings, and the shape and number of supports may be changed as needed.

[0037] The cooking unit (210) can be placed on the upper part of the stove body (100). However, if the cooking unit (210) is placed on the upper part of the stove body (100), both the stove body (100) and the cooking unit (210) will be heated. Therefore, if the cooking unit (210) falls off the upper part of the stove body (100), it may be dangerous. Accordingly, it is desirable for the cooking unit (210) to be placed more stably on the upper part of the stove body (100). To solve the technical problems described above, the present invention may further include a coupling auxiliary part (240) formed in the heat utilization part.

[0038] FIG. 2 is a partially exploded cross-sectional view of a multi-functional camping stove according to the first embodiment of the present invention.

[0039] As shown in FIG. 2, the coupling aid (240) is formed at the bottom of the cooking section (210) to make the coupling with the stove body (100) more stable. More specifically, the coupling aid (240) protrudes downward from the outer part of the lower surface of the cooking section (210).

[0040] The inner diameter of the connecting auxiliary part (240) may be equal to or larger than the upper outer diameter of the stove body (100).

[0041] As shown in FIG. 2, when the inner diameter of the coupling aid (240) is equal to the upper outer diameter of the stove body (100), the coupling aid (240) can be more stably coupled to the upper part of the stove body (100) when the coupling aid (240) and the stove body (100) are coupled to each other. However, if the inner diameter of the coupling aid (240) and the upper outer diameter of the stove body (100) are equal, the coupling aid (240) and the upper part of the stove body (100) must be precisely aligned, so the coupling of the coupling aid (240) and the stove body (100) itself may be difficult.

[0042] Conversely, if the inner diameter of the coupling aid (240) is larger than the upper outer diameter of the stove body (100), the coupling aid (240) does not need to be accurately positioned on the upper part of the stove body (100), so the coupling aid (240) can be more easily coupled to the upper part of the stove body (100), but there may be a disadvantage of reduced stability as the coupling aid (240) can move after coupling.

[0044] FIG. 3 is a partially exploded cross-sectional view of a multi-functional camping stove according to a second embodiment of the present invention.

[0045] As with the multi-functional camping stove according to the first embodiment of the present invention described above, if the inner diameter of the coupling auxiliary part (240) is larger than or equal to the upper outer diameter of the stove body (100) but constant, there may be disadvantages such as difficulty in coupling the coupling auxiliary part (240) to the upper part of the stove body (100), or even if coupled, the heat utilization part on which the coupling auxiliary part (240) is formed moves. To solve these problems, the coupling auxiliary part (240) of the present embodiment may have a guide section (241) formed such that the inner diameter of the lower part is formed to be larger than the upper part of the stove body (100), the inner diameter narrows as it goes upward, and finally the inner diameter is formed to be equal to that of the stove body (100).

[0046] This embodiment has the effect of allowing the user to more stably connect the heat utilization part to the top of the stove body (100) through the guide section, and to maintain a stably connected state even after connecting.

[0048] FIG. 4 is a partially exploded perspective view of a multi-functional camping stove according to the third embodiment of the present invention.

[0049] As shown in FIG. 4, the heat utilization unit of the multi-functional camping stove according to the third embodiment of the present invention includes a hot water generating unit (220).

[0050] The hot water generating unit (220) is connected to the top of the stove body (100) and is intended to heat the water inside by the heat generated from the stove body (100) and supply the heated water. As shown in FIG. 4, it includes a hot water generating unit (221), a water supply pipe (222), a water discharge pipe (223), a pump (224), and a water storage unit (225).

[0051] A space is formed inside the hot water generating body (221), and the water supply pipe (222) and the water discharge pipe (223) are each connected to the space formed inside the hot water generating body (221). Water flows in through the water supply pipe (222), and after the water is heated inside the hot water generating body (221), it is discharged through the water discharge pipe (223).

[0052] The hot water generating body (221) has a circular cross-section. However, the present invention is not limited thereto, and the cross-sectional shape of the hot water generating body (221) is not limited to a circular shape; the cross-section of the hot water generating body (221) may have various shapes such as a polygon, a circle, or an ellipse.

[0053] The internal space of the hot water generating body (221) may not be simply U-shaped, but may be in a circular shape wound at least once. This is because water has a high specific heat, so a certain amount of time is required to heat the water; if a U-shaped flow path is formed inside the hot water generating body (221), it may be difficult to secure the time required to heat the water. Therefore, the internal space of the hot water generating body (221) may have a shape in which the flow path is stacked in the height direction by rotating at least once, and both ends of the space may be connected to a water supply pipe (222) and a water discharge pipe (223), respectively.

[0054] A pump (224) is installed in at least one of the water supply pipe (222) and the water discharge pipe (223) to regulate the flow of water in the hot water generating unit (220). The pump (224) may be installed in the water supply pipe (222) because operating the pump (224) in a relatively low-temperature environment can ensure the reliability of the pump (224). However, if the pump (224) has specifications that allow it to operate in a high-temperature environment, the pump (224) may be installed in either the water supply pipe (222) or the water discharge pipe (223), and there may also be an embodiment in which two or more pumps (224) are installed in at least one of the water supply pipe (222) and the water discharge pipe (223).

[0055] The water storage section (225) is installed in the water supply pipe (222) and is a part where water supplied through the pump (224) is stored.

[0056] In the camping multi-functional stove according to the third embodiment of the present invention, the hot water generating unit (220) may be a component necessary for using a hot water mat. However, the present invention is not limited to the use of the hot water generating unit (220) as a hot water mat, and the hot water generated through the hot water generating unit (220) may be used for various purposes.

[0057] Although not shown in the drawing, the coupling auxiliary part (240) described above in the camping multi-functional stove according to the first and second embodiments of the present invention may also be applied to the lower surface of the hot water generating part (220).

[0058] Although not illustrated in the drawing, the water supply pipe (222) and water discharge pipe (223) described above may have flexible characteristics as a type of hose. In order for the water supply pipe (222) and water discharge pipe (223) to have flexible characteristics, the water supply pipe (222) and water discharge pipe (223) may be manufactured including synthetic resin and may have a corrugated structure such as a bellows as needed, so that their length can be adjusted by extending or contracting.

[0060] FIG. 5 is a partially exploded perspective view of a multi-functional camping stove according to the fourth embodiment of the present invention.

[0061] As illustrated in FIG. 5, the heat utilization unit of the multi-functional camping stove according to the fourth embodiment of the present invention includes a hot air generating unit (230).

[0062] The hot air generating unit (230) is connected to the top of the stove body (100) and generates and supplies heated air.

[0063] As shown in FIG. 5, the hot air generating unit (230) includes a hot air generating body (231), an air inlet pipe (232), an air outlet pipe (233), and a fan (234).

[0064] The hot air generating body (231) has a space formed inside, similar to the hot water generating body (221) described earlier. The air inlet pipe (232) and the air outlet pipe (233) can each be installed to be connected to the internal space of the hot water generating body (221).

[0065] The internal space of the hot air generating body (231) may be connected in a U-shape, but there may also be an embodiment in which the flow path is stacked in the height direction by rotating at least once, similar to the hot water generating body (221) described above.

[0066] A fan (234) is installed in an air inlet pipe (232) to regulate the flow of air in the hot air generating unit (230). Since the fan (234) ensures the reliability of the fan (234) itself by flowing low-temperature air, it may be preferable to install it in an air inlet pipe (232) through which relatively low-temperature air passes rather than in an air outlet pipe (233) through which relatively high-temperature air passes; however, if the operational reliability of the fan (234) is ensured in a high-temperature environment, there may also be an embodiment in which the fan (234) is installed in an air outlet pipe (233).

[0067] The air inlet pipe (232) and the air outlet pipe (233) may have flexible characteristics, similar to the water supply pipe (222) and the water outlet pipe (223) described earlier. To this end, the air inlet pipe (232) and the air outlet pipe (233) may be manufactured from a material having flexible characteristics to a certain degree, such as a synthetic resin material, and may have a corrugated structure.

[0068] The multi-functional camping stove according to the present embodiment has the effect of preventing carbon monoxide poisoning accidents caused by the stove body (100) when air heated from the outside is supplied into the tent by placing the stove body (100), the hot air generating body (231), and the air inlet pipe (232) outside and the air outlet pipe (233) inside the tent.

[0069] In this embodiment, the hot air generating part (230) also has a coupling auxiliary part (240) formed on its lower surface so that it can be stably coupled with the stove body (100).

[0071] FIG. 6 is a partially exploded perspective view of a multi-functional camping stove according to the fifth embodiment of the present invention.

[0072] As illustrated in FIG. 6, the multi-functional camping stove according to the fifth embodiment of the present invention includes a heat utilization unit that comprises the previously described cooking unit (210), hot water generating unit (220), and hot air generating unit (230). That is, as in this embodiment, the multi-functional camping stove according to the present invention means that the heat utilization unit may include at least two of the cooking unit (210), hot water generating unit (220), and hot air generating unit (230). In this embodiment, the heat utilization unit is described as including the cooking unit (210), hot water generating unit (220), and hot air generating unit (230).

[0073] As shown in FIG. 6, the heat utilization unit includes a cooking unit (210), a hot water generating unit (220), and a hot air generating unit (230) so that all of the cooking unit (210), the hot water generating unit (220), and the hot air generating unit (230) can be used with a single stove body (100).

[0074] Although the order in which the hot water generating unit (220) and the hot air generating unit (230) are arranged does not matter significantly, since more energy is required to heat the water, it may be preferable for the hot water generating unit (220) to be located lower than the hot air generating unit (230) when considering heat loss and heat transfer efficiency.

[0075] Additionally, among the cooking unit (210), hot water generating unit (220), and hot air generating unit (230), it is preferable that the cooking unit (210) be located at the very top. This is because, since a separate cooking tool is mounted on the upper part of the cooking unit (210) and cooking is performed thereon, if the hot water generating unit (220) and the hot air generating unit (230) are located on the upper part of the cooking tool, various foreign substances generated during the cooking process may contaminate the hot water generating unit (220) or the hot air generating unit (230). However, there may also be an embodiment in which a separate lid is formed on the cooking tool mounted on the cooking unit (210) as needed, and the hot water generating unit (220) or the hot air generating unit (230) is stacked on the upper part of the lid.

[0076] Additionally, there may also be an embodiment in which the lower surface of the hot water generating unit (220) or the hot air generating unit (230) acts as the lid of the cooking unit (210) depending on the situation.

[0077] The upper portions of the hot water generating portion (220) and the hot air generating portion (230) may have a connecting step portion (250) formed therein for connection with other components located above.

[0078] The combined step portion (250) is for combining the lower component and the upper component stacked thereon, and refers to a portion where the diameter becomes smaller.

[0079] For example, a hot air generating unit (230) is located above the hot water generating unit (220), and the connection between the hot water generating unit (220) and the hot air generating unit (230) needs to be stable. A connecting support unit (240) is formed below the hot air generating unit (230), and a connecting step (250) is formed on the upper surface of the hot water generating unit (220) so that the connection between the connecting support units (240) can be stable. To this end, the diameter of the connecting step (250) may be equal to or smaller than the lower inner diameter of the connecting support unit (240).

[0080] The aforementioned connecting step portion (250) is also formed on the upper part of the hot air generating portion (230), so that the connection with the cooking portion (210) located on the upper part of the hot air generating portion (230) can also be made more stable.

[0082] FIG. 7 is a lower perspective view of the cooking section of a multi-functional camping stove according to the 6th embodiment of the present invention.

[0083] As illustrated in FIG. 7, in this embodiment, the cooking unit (210) may include a heating control unit (260).

[0084] As illustrated in FIG. 7, the cooking section (210) in the present invention has a hole formed in the center. The formation of a hole may mean that the heat generated from the stove body (100) located at the bottom is not fully transferred to the cooking section (210). The heating control section (260) is configured to control the degree to which the heat generated from the stove body (100) is transferred to the cooking section (210), and is configured to partially or completely block the hole formed in the cooking section (210).

[0085] The heating control unit (260) can be implemented in various forms, and in the embodiment shown in FIG. 7, the heating control unit (260) may be formed by including a sliding member (262) which is inserted into the sliding space (261) and slid to partially block, completely open, or completely cover a hole formed in the cooking unit (210), wherein a sliding space (261) is formed on the lower surface of the cooking unit (210).

[0086] With reference to FIG. 7, in this embodiment, the heating control unit (260) is described as being formed in the cooking unit (210), but the heating control unit (260) can also be implemented in any component included in the heat utilization unit, such as the hot water generating unit (220), the hot air generating unit (230), etc.

[0087] In the various embodiments of the present invention described above, the cooking unit (210), hot water generating unit (220), and hot air generating unit (230) included in the heat utilization unit were all described as being separated from and combined with the stove body (100). However, the present invention is not limited to the cooking unit (210), hot water generating unit (220), and hot air generating unit (230) included in the heat utilization unit being separated from and combined with the stove body (100); there may also be embodiments in which at least one of the cooking unit (210), hot water generating unit (220), and hot air generating unit (230) included in the heat utilization unit is integrated with the stove body (100) as needed.

[0089] Although preferred embodiments of the present invention have been described above, the embodiments disclosed in the present invention are intended only to illustrate, not to limit, the technical scope of the present invention. Accordingly, the technical scope of the present invention includes not only each disclosed embodiment but also combinations of the disclosed embodiments, and furthermore, the scope of the technical scope of the present invention is not limited by such embodiments. In addition, a person skilled in the art to which the present invention pertains can make numerous changes and modifications to the present invention without departing from the spirit and scope of the appended claims, and all such appropriate changes and modifications should be deemed to fall within the scope of the present invention as equivalents.
