Description

Technical Field

[0001] This utility model relates to the field of outdoor stove technology, and more specifically, to a retractable multifunctional outdoor cooking set. Background Technology

[0002] Existing outdoor cooking kits typically have only one fixed support method and height, making it impossible to adjust the height of the cookware according to different cookware, cooking methods (such as frying or boiling), and flame height. This not only results in low applicability and an inability to meet diverse customer needs, but also affects cooking time and cooking results.

[0003] Furthermore, existing outdoor cooking kits typically use a one-piece stove shell, housing a single fuel (such as alcohol or combustible gas) within the shell, and then adding extra accessories (such as wind deflectors) to increase wind resistance. This method of adding extra accessories is not only difficult to store, but the accessories are also prone to being lost, making them inconvenient to use; moreover, while providing wind protection, the poor air intake results in a smaller flame, making it difficult for food to cook thoroughly; furthermore, a single fuel type and a single type of cookware cannot meet the diverse needs of users. Utility Model Content

[0004] To address at least one of the aforementioned problems, this utility model first provides a retractable multifunctional outdoor cooking kit, including a support frame, a stove shell assembly, and a cookware assembly for holding food. The support frame is detachably snapped into the stove shell assembly. The support frame includes a forward state housed within the stove shell assembly and a reverse state protruding from the stove shell assembly to accommodate different cookware sizes and / or flame heights.

[0005] Optionally, the inner wall of the furnace shell assembly is provided with a support block, and the bracket is provided with a support lug, which abuts against and limits the support block; the support lug is provided with a first arc-shaped part and a second arc-shaped part, the arc opening of the first arc-shaped part and the arc opening of the second arc-shaped part are opposite in orientation; when the bracket is in the forward state, the support block is adapted to engage with the first arc-shaped part; when the bracket is in the reverse state, the support block is adapted to engage with the second arc-shaped part.

[0006] Optionally, the support ear is further provided with a third arc-shaped portion, the arc opening of the first arc-shaped portion and the arc opening of the third arc-shaped portion are oriented in the same direction, the two ends of the second arc-shaped portion are respectively connected to the first arc-shaped portion and the third arc-shaped portion, the depth of the first arc-shaped portion is greater than the depth of the third arc-shaped portion, so as to adapt to different cookware sizes and / or flame heights; when the support is in the positive state, the support block is suitable for engaging with the first arc-shaped portion or the third arc-shaped portion.

[0007] Optionally, the furnace shell assembly includes an upper furnace shell and a lower furnace shell, both of which are vertically connected. The lower furnace shell has a forward state with the furnace opening facing upward and a reverse state with the furnace opening facing downward. When the lower furnace shell is in the forward state, the upper furnace shell and the lower furnace shell can be nested together, and the cooking utensil assembly can be stored on the upper furnace shell. When the lower furnace shell is in the reverse state and supported below the upper furnace shell, a windproof cavity suitable for accommodating flames is formed between the upper furnace shell, the lower furnace shell, and the ground. The cooking utensil assembly is placed on the furnace shell assembly, and food is cooked by flames.

[0008] Optionally, the lower furnace shell is provided with a plurality of first air holes and a plurality of second air holes. The first air holes are concentrated on one half of the outer side wall of the lower furnace shell. The axis of the first air hole is parallel to the horizontal plane, and the axis of the second air hole is perpendicular to the horizontal plane. Both the first air holes and the second air holes are connected to the windproof cavity. The first air holes and the second air holes are used for air intake to provide air for flame combustion. The upper furnace shell is provided with a fire observation port. The fire observation port facilitates observation of the flame status and adjustment of the flame size. The fire observation port is located on the side of the upper furnace shell away from the first air holes.

[0009] Optionally, it also includes an elastic strap with hooks at both ends and a handle on the outer wall of the lower furnace shell; when in the storage state, the hooks and the handle are hooked together.

[0010] Optionally, the bottom of the upper furnace shell is provided with a connecting port, and the bottom of the lower furnace shell is provided with a connecting seat. The connecting seat is provided with a radially protruding limiting block and a limiting opening axially aligned with the limiting block. The inner wall of the connecting port is provided with a clearance opening for avoiding the limiting block. The clearance opening and the limiting block are slidably connected vertically, and the inner wall of the connecting port and the limiting opening are rotatably connected. When the lower furnace shell is in the reverse state, the clearance opening passes through the limiting block and rotates after reaching the clearance opening, so that the clearance opening and the limiting block are misaligned, and the bottom limiting of the upper furnace shell is installed in the clearance opening.

[0011] Optionally, the cooking utensil assembly includes at least one of a pot, a kettle, and a frying pan, wherein the pot, the kettle, and the frying pan can be nested and stored together; the pot includes a pot body and a pot lid, the height of the pot body is greater than the height of the kettle, the kettle can be stored in the pot body, and the pot lid is placed on the pot body; when stored, the pot is housed in the oven shell assembly, and the frying pan is placed on the oven shell assembly in the opposite direction.

[0012] Optionally, it also includes a fuel assembly, wherein the furnace shell assembly, the support, and the cooking appliance assembly can be nested together. The furnace shell assembly is provided with a fuel installation port suitable for installing the fuel assembly. The fuel assembly is an alcohol stove or a gas stove. The alcohol stove is provided with an alcohol chamber for containing alcohol. The gas stove includes a valve, a coil, a preheating pipe, and a stove plate. The valve is used to connect to an external gas cylinder / canister. The two ends of the coil are respectively connected to the valve and the preheating pipe. The preheating pipe is connected to the stove plate and is used to preheat and vaporize the liquefied gas in the gas cylinder / canister and then deliver it to the stove plate.

[0013] Optionally, the outer wall of the alcohol furnace is provided with a flange, the diameter of which is larger than the diameter of the fuel installation port, and the flange abuts against the fuel installation port vertically; the gas furnace also includes a snap-fit ​​component, which is coaxially fixed to the bottom of the furnace plate, and the snap-fit ​​component is provided with a plurality of elastic snap-fit ​​arms, which are arranged around the furnace plate, and the snap-fit ​​arms are provided with snap-fit ​​grooves, which snap into the inner wall of the fuel installation port.

[0014] Compared to existing technologies, the collapsible, multi-functional outdoor cooking kit of this invention features a reversible stand design that provides two different support heights. The height of the cookware can be adjusted according to different cookware, cooking methods (such as frying or boiling), and flame heights, making it highly adaptable, meeting diverse customer needs, and reducing cooking time.

[0015] The limiting structure of the support block and lugs ensures that the bracket can be stably locked in both states, preventing slippage or tipping during use and improving operational safety and reliability. When using a pot or kettle, the bracket is in the upright position, supporting the bottom of the pot or kettle. This prevents the pot or kettle from directly contacting the combustion components inside the upper furnace shell, which could extinguish the flame. At the same time, it allows the pot or kettle to be almost completely contained within the upper furnace shell, maximizing heat conduction and wind protection, thus speeding up the boiling time or cooking time.

[0016] Because the frying pan is placed on the upper oven shell when stored, the diameter of the frying pan is larger than that of the upper oven shell. When cooking, the frying pan is placed on the upper oven shell, and the support is in the reverse position. The support supports the bottom of the frying pan and raises the height of the frying pan, avoiding direct contact between the frying pan and the upper part of the upper oven shell. This prevents the upper part of the upper oven shell from being sealed, thus avoiding insufficient oxygen intake that could lead to incomplete combustion or flameout.

[0017] Different fuels produce different flame heights, and the outer flame temperature is higher. The height of the cookware can be fine-tuned by adjusting the locking mechanism of the support bracket to accommodate these different flame heights. Specifically, the flame height of an alcohol stove is lower than that of a gas stove. Therefore, when using an alcohol stove and the support bracket is in the forward position, the support block can be engaged with the first arc-shaped part, lowering the support surface height to match the outer flame height of the alcohol stove. When using a gas stove and the support bracket is in the forward position, the support block can be engaged with the third arc-shaped part, relatively raising the support surface height to match the outer flame height of the gas stove. When the support bracket is in the reverse position, because it is farther from the flame, no height adjustment is needed; simply engaging the support block with the second arc-shaped part is sufficient.

[0032] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0033] This utility model embodiment provides a retractable, multi-functional outdoor cooking kit, combined with... Figures 1 to 12 As shown, the device includes a furnace shell assembly, a fuel assembly, and a cooking utensil assembly for containing food. The furnace shell assembly, the fuel assembly, and the cooking utensil assembly can be nested together. The furnace shell assembly includes an upper furnace shell 1 and a lower furnace shell 2, both of which are vertically connected. The lower furnace shell 2 has a forward state with the furnace opening facing upwards and a reverse state with the furnace opening facing downwards. When the lower furnace shell 2 is in the forward state, the upper furnace shell 1 and the lower furnace shell 2 can be nested together. When the lower furnace shell 2 is in the reverse state and supported below the upper furnace shell 1, a windproof cavity suitable for containing the fuel assembly is formed between the upper furnace shell 1, the lower furnace shell 2, and the ground. The flame generated by the combustion of the fuel assembly is located in the windproof cavity, and the cooking utensil assembly is placed on the furnace shell assembly to cook food by the flame.

[0034] like Figure 1 and Figure 11 As shown, in this embodiment, the diameter of the lower furnace shell 2 is larger than that of the upper furnace shell 1. This not only allows the upper furnace shell 1 to be nested and stored within the lower furnace shell 2, but also provides more stable support for the lower furnace shell 2 during cooking. By designing the lower furnace shell 2 to have both forward and reverse orientations, a clever unification of "use" and "storage" modes is achieved. Both the upper furnace shell 1 and the lower furnace shell 2 are made of hard anodized aluminum alloy. Hard anodized aluminum alloy is wear-resistant, heat-resistant, and corrosion-resistant, making it sturdy and wear-resistant, suitable for outdoor use.

[0035] When used in the forward orientation, the lower furnace shell 2 fits over the upper furnace shell 1, reducing the overall size and making it easier to store and carry. When used in the reverse orientation, no additional independent windbreak accessories are needed. The upper furnace shell 1, the reversed lower furnace shell 2, and the ground naturally form a complete "windproof cavity," protecting the flame inside. This fundamentally solves the pain points of traditional outdoor stove windbreak accessories being easily lost and difficult to store. The formed "windproof cavity" not only effectively resists the direct impact of side winds on the flame, preventing heat loss, but also makes the flame more stable and the heat more concentrated on the bottom of the cookware, thus significantly shortening the heating time and solving the problems of insufficient heat and food not cooking properly.

[0036] like Figures 1 to 3 As shown, optionally, the cooking utensil assembly includes at least one of a pot 5, a kettle 6, and a frying pan 7, wherein the pot 5, the kettle 6, and the frying pan 7 can be nested and stored together.

[0037] In this embodiment, by providing a variety of cooking utensils—a pot 5, a kettle 6, and a frying pan 7—and ensuring that they can be nested together, the system greatly satisfies the diverse cooking needs of users in outdoor scenarios. It can handle tasks such as boiling water with the kettle 6, cooking with the pot 5, and frying with the frying pan 7. This multi-functional design avoids the hassle of carrying multiple sets of separate utensils for different cooking tasks. By designing mutually adaptable diameters and heights, all the utensils are integrated into a compact cylinder when stored, minimizing space occupation and improving the portability of the entire set.

[0038] like Figure 2 and Figure 3 As shown, optionally, the cookware 5 includes a pot body 51 and a pot lid 52. The height of the pot body 51 is greater than the height of the kettle 6. The kettle 6 can be stored in the pot body 51. The pot lid 52 is placed on the pot body 51. When stored, the cookware 5 is housed in the upper furnace shell 1, and the frying pan 7 is placed on the upper furnace shell 1 in reverse.

[0039] In this embodiment, the pot body 51 serves as the main container, housing the kettle 6. The pot lid 52 is placed on top of the kettle 6, and finally, the frying pan 7 serves as the "top cover" to complete the final sealing. The upper oven shell 1, pot body 51, and kettle 6 are nested between the lower oven shell 2 and the frying pan 7. This layered nesting structure allows cookware of various shapes and functions to be stored and integrated together, not only maximizing space utilization but also forming a sturdy whole, effectively preventing collisions and wear between components during transportation or carrying.

[0040] Both the pot body 51 and the frying pan 7 are equipped with rotatable and foldable handles, and both the pot lid 52 and the kettle 6 are equipped with rotatable and foldable handles.

[0041] like Figure 4 , Figure 5 , Figure 12 As shown, optionally, it also includes a bracket 8, which includes a forward state accommodated in the upper furnace shell 1 and a reverse state protruding from the upper furnace shell 1 to adapt to different cookware sizes. The inner wall of the upper furnace shell 1 is provided with a support block 14, and the bracket 8 is provided with a support ear 81, which abuts against and limits the support block 14 in both directions.

[0042] In this embodiment, the flip-up support 8 is designed to provide two different support heights. The height at which the cookware is placed can be adjusted according to different cookware, cooking methods (such as frying or boiling), and flame heights. This not only makes it highly adaptable and meets diverse customer needs, but also reduces cooking time.

[0043] There are two or more support blocks 14. The limiting structure of the support blocks 14 and the lugs 81 ensures that the bracket 8 can be stably locked in both states, preventing slippage or tipping during use and improving the safety and reliability of operation. When using the pot 5 or kettle 6, the bracket 8 is in the positive state, supporting the bottom of the pot 5 or kettle 6, preventing the pot 5 or kettle 6 from directly contacting the combustion components inside the upper furnace shell 1, which would cause the flame to be extinguished. At the same time, it allows the pot 5 or kettle 6 to be almost completely contained in the upper furnace shell 1, achieving maximum heat conduction and wind protection, and speeding up the boiling time or cooking time of water or food.

[0044] Because the frying pan 7 is placed on top of the upper oven shell 1 during storage, the diameter of the frying pan 7 is larger than the diameter of the upper oven shell 1. When cooking, the frying pan 7 is placed on the upper oven shell 1, at which point the support 8 is in the reverse position. The support 8 supports the bottom of the frying pan 7, raising its height and preventing direct contact between the frying pan 7 and the upper part of the upper oven shell 1, thus sealing the upper part of the upper oven shell 1 and preventing incomplete combustion or flameout due to insufficient oxygen. When the support 8 is in the reverse position, the diameter of the cookware that can be supported on the support 8 is not limited by the diameter of the upper oven shell 1, making it compatible with a wider range of cookware diameters available on the market, thus broadening its applicability.

[0045] like Figure 4 , Figure 11 , Figure 12As shown, optionally, the support lug 81 is provided with a first arc-shaped portion 82, a second arc-shaped portion 83, and a third arc-shaped portion 84. The arc opening of the first arc-shaped portion 82 and the arc opening of the third arc-shaped portion 84 face the same direction, while the arc opening of the second arc-shaped portion 83 faces the opposite direction to the arc opening of the first arc-shaped portion 82. The two ends of the second arc-shaped portion 83 are respectively connected to the first arc-shaped portion 82 and the third arc-shaped portion 84. The depth of the first arc-shaped portion 82 is greater than the depth of the third arc-shaped portion 84. When the bracket 8 is in the forward state, the support block 14 is adapted to engage with the first arc-shaped portion 82 or the third arc-shaped portion 84. When the bracket 8 is in the reverse state, the support block 14 is adapted to engage with the second arc-shaped portion 83.

[0046] In this embodiment, multiple arc-shaped portions on the support lug 81 form a clever "multi-position" positioning mechanism. The first arc-shaped portion 82 and the third arc-shaped portion 84 provide two different engagement depths for the forward position, which can be freely adjusted by the user according to the size of the cookware, making it more versatile and meeting different usage needs. The second arc-shaped portion 83 provides a solid support point for the reverse position. This design is simple in structure and low in cost, making the state transition of the support 8 simple and convenient, and ensuring stable engagement.

[0047] like Figure 2 As shown, optionally, it also includes an elastic strap 9, with hooks 91 at both ends of the strap 9, and a handle 26 on the outer wall of the lower furnace shell 2; when in the storage state, the hooks 91 and the handle 26 are hooked together.

[0048] In this embodiment, the combination of the elastic strap 9 and the handle 26 provides a simple and effective securing solution for the entire set of equipment in its stored state. The elastic strap 9 can adapt to slightly different storage volumes and apply continuous tightening force to prevent the nested components from loosening or separating due to bumps during transport. The hook-and-lock connection between the hook lock 91 and the handle 26 is simple to operate and easy to understand, further enhancing the integrity and portability of the entire cooking set and avoiding the risk of it falling apart. At the same time, the handle 26 also makes it easy to lift the lower oven shell 2 for flipping operations or to lift the entire cooking set.

[0049] like Figure 9 and Figure 10As shown, optionally, the bottom of the lower furnace shell 2 is provided with a fuel installation port 27 suitable for installing the fuel assembly. The fuel assembly is an alcohol furnace 3 or a gas furnace 4. The alcohol furnace 3 is provided with an alcohol chamber for containing alcohol. The gas furnace 4 includes a valve 41, a coil 42, a preheating pipe 43, and a furnace plate 44. The valve 41 is used to connect to an external gas cylinder / canister. The two ends of the coil 42 are respectively connected to the valve 41 and the preheating pipe 43. The preheating pipe 43 is connected to the furnace plate 44. The preheating pipe 43 is used to preheat and vaporize the liquefied gas in the gas cylinder / canister and then transport it to the furnace plate 44.

[0050] In this embodiment, a single fuel installation port 27 is compatible with both alcohol stove 3 and gas stove 4, two mainstream outdoor fuel systems, solving the problem of limited fuel variety and meeting diverse user needs. The alcohol stove 3 or gas stove 4 can be stored in a kettle 6. The preheating tube 43 utilizes the heat generated by combustion to preheat and vaporize the liquefied gas. After being sprayed from the burner plate 44, it mixes better with oxygen for more complete combustion. Simultaneously, as the internal pressure of the gas canister gradually decreases during use, the preheating tube 43 maintains a stable power output during combustion on the burner plate 44, even with pressure changes. This ensures stable and efficient gas combustion even in low-temperature environments, maintaining a stable flame output.

[0051] When using different fuels, the flame height varies, and the outer flame temperature is higher. The height of the cookware can be fine-tuned by adjusting the locking mechanism of the support 8 to accommodate different flame heights. Specifically, the flame height produced by the alcohol stove 3 is lower than that produced by the gas stove 4. Therefore, when the alcohol stove 3 is used and the support 8 is in the forward position, the support block 14 can be engaged with the first arc-shaped part 82, lowering the support surface height of the support 8 to match the outer flame height of the alcohol stove 3. When the gas stove 4 is used and the support 8 is in the forward position, the support block 14 can be engaged with the third arc-shaped part 84, relatively raising the support surface height of the support 8 to match the outer flame height of the gas stove 4. When the support 8 is in the reverse position, because it is farther from the flame, no height adjustment is needed; simply engaging the support block 14 with the second arc-shaped part 83 is sufficient.

[0052] like Figure 9 and Figure 10As shown, optionally, the outer wall of the alcohol furnace 3 is provided with a flange 31, the diameter of which is larger than the diameter of the fuel installation port 27. When the lower furnace shell 2 is in the reverse state, the bottom of the flange 31 abuts against the bottom of the fuel installation port 27. The gas furnace 4 also includes a snap-fit ​​member 45, which is coaxially fixed to the bottom of the furnace plate 44. The snap-fit ​​member 45 is provided with a plurality of elastic snap-fit ​​arms 46, which are arranged around the furnace plate 44. The snap-fit ​​arms 46 are provided with snap-fit ​​grooves 47, which snap into the inner wall of the fuel installation port 27.

[0053] In this embodiment, specific fixing methods were designed to address the structural characteristics of different fuel assemblies. The alcohol furnace 3 uses a simple flange 31 for contact and positioning, ensuring a reliable structure. The gas furnace 4 employs a flexible snap-fit ​​mechanism, achieving quick installation and locking with a "click" sound through the deformation of the snap-fit ​​arm 46. Both methods ensure that the fuel assembly is securely positioned within the furnace shell assembly during combustion and use, making installation convenient and quick.

[0054] like Figure 7 and Figure 8 As shown, optionally, the bottom of the upper furnace shell 1 is provided with a connecting port 11, and the bottom of the lower furnace shell 2 is provided with a connecting seat 21. The connecting seat 21 is provided with a radially protruding limiting block 22 and a limiting port 23 axially aligned with the limiting block 22. The inner wall of the connecting port 11 is provided with a clearance port 12 for avoiding the limiting block 22. The clearance port 12 and the limiting block 22 are slidably connected vertically, and the inner wall of the connecting port 11 and the limiting port 23 are rotatably connected. When the lower furnace shell 2 is in the reverse state, the clearance port 12 passes through the limiting block 22 and rotates after reaching the clearance port 12, so that the clearance port 12 and the limiting block 22 are misaligned, and the bottom of the upper furnace shell 1 is limited and installed in the clearance port 12.

[0055] In this embodiment, the upper furnace shell 1 and the lower furnace shell 2 are connected by a rotating snap-fit ​​mechanism, enabling rapid assembly and disassembly. Users do not need any tools; they only need to align, insert, and rotate to complete the stable assembly of the furnace body. The misalignment design of the limiting block 22 and the clearance opening 12 forms a mechanical interlock, which can reliably withstand the weight of the cookware and the stress generated during operation, ensuring the rigidity and stability of the entire furnace structure during use.

[0056] like Figure 7 and Figure 8As shown, optionally, the outer wall of the lower furnace shell 2 is provided with a plurality of first air holes 24, and the connecting seat 21 is provided with a plurality of second air holes 25. The hole axis of the first air holes 24 is parallel to the horizontal plane, and the hole axis of the second air holes 25 is perpendicular to the horizontal plane. The first air holes 24 and the second air holes 25 are both connected to the windproof cavity. The first air holes 24 and the second air holes 25 are used for air intake to provide air for the combustion of the fuel assembly. The upper furnace shell 1 is provided with a fire observation port 13. The fire observation port 13 facilitates the observation of the flame state and adjustment of the flame size. The fire observation port 13 is located on the side of the upper furnace shell 1 away from the first air holes 24.

[0057] In this embodiment, the first vent 24, concentrated on one side of the lower furnace shell, prevents direct horizontal airflow, thus preventing the flame from being blown out and resulting in poor combustion. The first vent 24 and the second vent 25 work together to form a "chimney effect," optimizing airflow and creating a stable and sufficient airflow channel for combustion within the windproof chamber, ensuring complete fuel combustion and a vigorous flame. The observation port 13 allows the user to observe the flame color and height without lifting the cooking appliance, facilitating timely adjustment of the gas valve or the ventilation cover of the alcohol stove 3 to control the firepower. Simultaneously, the observation port 13 is connected to the ventilation chamber, further enhancing airflow, ensuring complete combustion, and reducing carbon monoxide concentration.

[0058] Similarly, the components included in the "components," "mechanisms," and "devices" of this disclosure can also be flexibly combined.
