Description

Technical Field

[0001] This utility model relates to the field of outdoor equipment technology, and in particular to a portable folding gas barbecue grill. Background Technology

[0002] With the increasing demand for outdoor leisure activities such as picnics, camping, and road trips, portable barbecue grills have become widely popular due to their portability and ability to enjoy barbecues anytime, anywhere. Among the many portable barbecue grills available, gas-fired barbecue grills are gradually becoming one of the mainstream choices in the market due to their advantages such as rapid ignition, convenient heat adjustment, and relatively easy cleaning.

[0003] However, existing portable barbecue grills have simplified their features for portability, resulting in relatively limited functionality that fails to meet users' diverse needs for convenient operation, stable use, and easy maintenance.

[0004] Many portable stoves only retain the core combustion and grilling areas, neglecting the user's need for temporary storage space during actual grilling. This makes it inconvenient for users to place food, seasonings, or grilling tools, affecting the smoothness of operation and the user experience. Some portable stoves, in order to simplify their structure, require the use of external ignition devices such as lighters, increasing the difficulty of operation and potential safety risks. In pursuit of extreme lightweighting and miniaturization, some products have flimsy support leg structures, lacking effective lateral stability and deployment limiting mechanisms, resulting in poor stability when used on uneven outdoor ground, posing a risk of tipping over.

[0005] Therefore, existing portable barbecue grills need to be improved to overcome the shortcomings of the existing technology. Utility Model Content

[0006] To overcome the problems existing in related technologies, the purpose of this utility model is to provide a portable folding gas barbecue grill. This portable folding gas barbecue grill has core connecting parts on both sides of its lower furnace chamber. These connecting parts are used to pivotally connect foldable support leg assemblies with angle limits and lateral stabilizing bars, side storage platforms that can be flattened and unfolded, and the ignition button of a piezoelectric igniter. At the same time, an oil collection assembly with sliding rails is set at the bottom of the lower furnace chamber, and an inverted V-shaped heat spreader is set above the gas burner. This integrated structural design overcomes the problems of existing portable barbecue grills, such as limited functionality, lack of convenient storage space, need for external ignition, insufficient stability of the support legs, and inconvenience in collecting and cleaning oil stains.

[0007] A portable folding gas grill includes:

[0008] The furnace body includes a lower furnace chamber and an upper furnace cover. The rear edges of the lower furnace chamber and the upper furnace cover are hinged together. The front edges of the lower furnace chamber and the upper furnace cover are provided with interlocking locking mechanisms. The top of the upper furnace cover is provided with a handle. Several ventilation holes are opened on the side wall of the lower furnace chamber. Connectors are fixed on both sides of the lower furnace chamber. An oil drain opening is provided at the bottom of the lower furnace chamber. An oil collecting assembly is provided at the bottom of the lower furnace chamber. The oil collecting assembly includes a slide rail and an oil collecting box fixed to the bottom of the lower furnace chamber. The oil collecting box is positioned directly opposite the oil drain opening. The two sides of the oil collecting box are slidably engaged with the slide rail.

[0009] A gas burner, wherein the gas burner is a hollow elongated tube, the gas burner is installed in the lower furnace along the width direction of the lower furnace, and at least two rows of flame holes are evenly opened on the tube wall of the gas burner along the length direction.

[0010] A piezoelectric igniter, the piezoelectric igniter including an ignition button fixed on the connector and an ignition needle extending from the ignition button to the gas burner;

[0011] A heat spreader plate is mounted above the gas burner. The heat spreader plate has an inverted V-shaped cross-section and multiple upward-protruding guide strips on its upper surface.

[0012] A baking rack is placed above the heat spreader.

[0013] Two pairs of outrigger assemblies, each outrigger assembly including two outrigger rods and a lateral stabilizing rod connecting the two outrigger rods, the outrigger rods being pivotally connected to the connecting member and being foldable or unfoldable relative to the connecting member; the connecting member is provided with an angle limiting block, the angle limiting block being used to limit the unfolding range of the outrigger rod;

[0014] Two side shelves are pivotally connected to the connector via a pivot, and can be folded up or unfolded relative to the connector.

[0015] Furthermore, a windproof and storage plate is provided on the rear side of the lower furnace chamber. The windproof and storage plate is pivotally connected to the lower furnace chamber. Support rods are provided on both sides of the windproof and storage plate. The support rods are movably connected to the windproof and storage plate. The end of the support rod is provided with a latch for engaging the side storage platform.

[0016] In windy conditions, the windbreak and storage panel can be erected to effectively block side and rear drafts, reducing the impact of wind on the fire and preventing it from swaying or going out, thus ensuring combustion stability and heat concentration, and improving grilling efficiency. When the windbreak function is not in use, it can provide additional storage space or stabilize its position when erected by using support rods (e.g., the support rods are clipped onto the side storage platform, forming an additional platform or slope) or its own structure. The clipping between the support rods and the side storage platform utilizes existing structures to enhance the stability of the windbreak when erected or expand its storage function.

[0017] Furthermore, the side shelf includes a support frame and a movable base plate. The support frame is provided with a support net. The movable base plate and the support frame are both pivotally connected to the connector. The movable base plate and the support frame can rotate independently. The movable base plate and the support frame are detachably connected.

[0018] When the movable base plate is connected to the support frame, it forms a shelf surface with a partial mesh (support mesh) and a partial solid structure (movable base plate), or the movable base plate can act as a support under the support mesh to prevent small items from falling through the mesh. Since both can be rotated and disassembled independently, users can choose to use only the support frame with the support mesh (e.g., when ventilation or drainage is needed), or rotate the movable base plate to different positions as needed.

[0019] Furthermore, the movable base plate is snapped into the support frame.

[0020] This quick connection method, achieved through elastic deformation or specific structural embedding, requires no additional tools. Users can easily fix the movable base plate to the support frame by simply pressing or aligning it, and disassembly is equally convenient. It provides a quick, stable, and tool-free connection and separation method between the movable base plate and the support frame, further enhancing the ease of switching functions and cleaning and maintenance of the side shelf.

[0021] Furthermore, a ground stake rope is fixed to the bottom of the outrigger rod, and the ground stake rope is used to connect to the ground through ground stake accessories.

[0022] Ground stake ropes are fixed to the bottom of the outriggers, used to connect the outriggers to the ground via ground stake accessories. On soft or uneven ground, or in windy conditions, ground stakes are driven into the ground, and then the outriggers are connected and secured to the ground stakes using the ground stake ropes. The outriggers of the barbecue grill are then firmly anchored to the ground. This significantly enhances the stability of the barbecue grill in complex outdoor ground conditions or windy environments, effectively preventing tipping or displacement due to uneven ground or external disturbances, thus improving safety during use.

[0023] Furthermore, a heat spreader support is provided on one side wall of the lower furnace chamber, and the heat spreader support is connected to one end of the heat spreader. An adjustment opening is opened on the opposite side wall of the lower furnace chamber, and a screw is provided on the other end of the heat spreader. The screw passes through the adjustment opening into the lower furnace chamber and is connected to the lower furnace chamber through a nut connector.

[0024] One end of the heat spreader is fixed by a bracket (or serves as a pivot point), while the other end is connected to the lower furnace chamber via a screw and nut connector. By rotating the nut connector, the screw can be moved up and down within the adjustment opening (or the heat spreader can be rotated around the bracket end), thereby changing the height or tilt angle of the heat spreader relative to the gas burner. Adjusting the position of the heat spreader changes its distance and relative posture to the burner flame and the upper grill rack, thus affecting the heat conduction efficiency and the uniformity of heat distribution. Users can adjust the position according to the needs of the food being grilled (e.g., whether high heat for quick grilling or low heat for slow grilling).

[0025] Furthermore, the gas burner includes a closed end and an open end, the open end being used to connect to a gas source;

[0026] The closed end of the gas burner is fixedly connected to one side wall of the lower furnace chamber, and a fixing hole is opened on the opposite side wall of the lower furnace chamber. The open end of the gas burner passes through the fixing hole and exits the lower furnace chamber.

[0027] The closed end of the gas burner is fixed to one side wall of the lower furnace, while its open end (the part connecting to the gas pipeline) protrudes through a fixing hole on the other side wall. This two-point fixing method ensures that the burner is accurately and stably positioned within the furnace, preventing displacement due to vibration or handling. The open end protruding from the furnace facilitates connection to an external gas source, while the fixing hole design also provides positioning and protection for the protruding part, ensuring precise positioning of the burner within the furnace. This promotes stable flame output and efficient heat utilization, while also facilitating the connection of external gas pipelines.

[0028] Furthermore, the connector is provided with a first pin hole, and the support rod is provided with a second pin hole. When the support rod is extended to a preset angle, the first pin hole and the second pin hole are concentric. The first pin hole and the second pin hole are used to insert a pin to fix the support rod to the connector.

[0029] When the outrigger extends to the preset working angle determined by the angle limiting block, the first pin hole on the connector aligns with the second pin hole on the outrigger. Inserting the pin at this point rigidly locks the outrigger to the connector. This pin locking method provides stronger resistance to deformation and accidental folding than simple angle limiting blocks (usually surface or line contact limiting), especially when the grill is carrying heavy items or subjected to lateral forces, effectively preventing the outrigger from wobbling or accidentally retracting. This significantly enhances the stability and load-bearing capacity of the outrigger, prevents accidental folding, and improves safety during use.

[0030] Furthermore, the outrigger rod is provided with a protruding spring, and the connector is provided with a positioning hole. When the outrigger rod is extended to a preset angle, the protruding spring is engaged with the positioning hole.

[0031] As the outrigger extends, its protruding spring (a spring-loaded pin or ball) slides across the surface of the connector. When the outrigger reaches the preset extension angle, the protruding spring aligns precisely with the positioning hole on the connector and automatically engages in the hole under the spring force. This locking method is simple to operate; users can confirm the lock by the "click" sound or tactile feedback of the protruding spring engaging the positioning hole when extending the outrigger, simplifying the locking operation and effectively preventing the outrigger from accidentally retracting, thus ensuring stability during use.

[0032] Furthermore, the connector is provided with a third pin hole, and the side shelf is provided with a fourth pin hole. When the side shelf is in a flattened state, the third pin hole and the fourth pin hole are concentric. The third pin hole and the fourth pin hole are used to insert a pin to fix the side shelf to the connector.

[0033] When the side shelf is flipped to its horizontal, flat working position, the third pin hole on the connector aligns with the fourth pin hole on the side shelf. Inserting the pin at this point will rigidly lock the side shelf to the connector. This locking method effectively prevents the side shelf from accidentally tipping over or shaking due to accidental contact or excessive weight (within a certain range), ensuring the safety of items placed on it. It ensures the side shelf is securely locked in a horizontal working position when unfolded, improving its load-bearing stability and safety, and preventing items from falling due to accidental contact.

[0034] The beneficial effects of this utility model are as follows:

[0035] This utility model provides a portable folding gas grill. The grill body is designed to include hinged upper and lower lids, a front locking mechanism, a top handle, and a lower chamber with ventilation holes. Connecting members are fixed to both sides of the lower chamber, and these connecting members form the core to pivotally connect two pairs of foldable support legs equipped with lateral stabilizing rods and angle limiting blocks, as well as two side shelves that can be folded flat. A gas burner is horizontally mounted inside the lower chamber, with a heat spreader and grill rack arranged above it. An oil drain opening and oil collection assembly are located at the bottom of the lower chamber. A piezoelectric igniter is used, activated by an ignition button and ignition needle. When carried, the upper and lower lids are tightly closed by the locking mechanism, and the handle is easy to grip. The support legs and side shelves can be folded and stored on both sides of the grill body. Upon arrival at the location of use, the support legs can be quickly unfolded, with angle limiting blocks ensuring a stable support angle and lateral stabilizing rods enhancing structural stability; simultaneously, the side shelves can be folded flat. The piezoelectric igniter is triggered by an ignition button located on the connector. The ignition needle ignites the horizontally mounted gas burner, whose multiple flame holes ensure a wide flame coverage. The flame heats the inverted V-shaped heat spreader, and the guide strips on the heat spreader guide the hot airflow evenly onto the grill rack above, achieving uniform heating of the food. Ventilation holes in the lower chamber ensure complete combustion. Users can conveniently place ingredients, seasonings, and tools on the unfolded side shelf. Some of the grease and residue produced during grilling will drip into the oil collection assembly through the oil drain opening at the bottom of the lower chamber, guided by the grill rack and heat spreader. The oil collection box, due to its sliding engagement with the rails, can be easily pulled out from the bottom of the oven for emptying and cleaning. This invention organically combines portability, a stable unfolding structure, convenient ignition and operation, uniform heating performance, and an easy-to-clean oil stain treatment system, thereby overcoming the shortcomings of existing portable stoves such as limited functionality, inconvenient operation, or insufficient stability. It provides users with a portable folding gas grill solution that is comprehensive in function, convenient to use, offers a superior user experience, and is easy to maintain.

[0051] Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.

[0052] Example 1

[0053] like Figures 1 to 5 As shown, this embodiment provides a portable folding gas grill, which includes an openable and foldable metal grill body 100.

[0054] The furnace body 100 consists of a lower furnace chamber 110 and an upper furnace cover 120 that can be closed onto it. The rear long sides of the lower furnace chamber 110 and the upper furnace cover 120 are connected by a set of hinges, allowing the upper furnace cover 120 to be opened and closed. To keep the furnace body 100 closed when carried or not in use, the front long sides of the lower furnace chamber 110 and the upper furnace cover 120 are each provided with a set of interlocking locking mechanisms 130, such as latch-type locks. A handle 140 is installed at the top center of the upper furnace cover 120 for easy lifting and moving of the entire furnace. Multiple rows of ventilation holes 111 are distributed on the left and right side walls of the lower furnace chamber 110. These holes can be elongated or elliptical, and their function is to ensure air supply during combustion and to help regulate the temperature inside the furnace.

[0055] On the left and right outer surfaces of the lower furnace chamber 110, connectors 200 serving as connecting platforms are fixed. These connectors 200 can be extensions integrally formed with the side walls of the furnace body 100, or additional riveted or welded metal plates. The inner bottom surface of the lower furnace chamber 110 is designed with a slope, allowing excess grease generated during grilling to flow to the lowest point. At the lowest point, one or more grease drain openings 112 are provided. Correspondingly, on the outer bottom surface of the lower furnace chamber 110, a pull-out grease collection assembly 300 is integrated. This assembly consists of a pair of parallel metal slide rails 310 and a shallow, disc-shaped grease collection box 320 that can be embedded in and move along the slide rails 310. During use, the grease collection box 320 is located below the grease drain openings 112 to collect dripping grease and food residue, and can be pulled out for cleaning after use.

[0056] The heating element inside the furnace is a gas burner 400. This is a horizontally arranged, elongated, hollow metal tube, the length of which roughly matches the internal width of the lower furnace chamber 110. On both sides of the burner tube, along its length, at least two rows of small flame outlet holes 410 are evenly drilled, a design that helps the flame to form a wider coverage area.

[0057] In this embodiment, one end of the gas burner 400 is sealed, while the other end remains open for connection to an external gas supply. The sealed end is fixed to the inner wall of one side of the lower furnace chamber 110 via a clamp or screws. On the opposite side wall of the lower furnace chamber 110, a fixing hole matching the burner's pipe diameter is provided. The open port of the burner extends out of the furnace body 100 through this hole, facilitating connection of the gas cylinder's pressure regulating valve and hose. This installation method ensures a relatively stable position of the burner within the furnace chamber and facilitates easy operation of the gas interface.

[0058] To ignite the gas, the stove is equipped with a piezoelectric igniter 500. The ignition button of the igniter is mounted on the connector 200, or in an easily accessible location on the side wall of the stove body 100. The button is connected via an internal wire to an ignition needle with ceramic insulation. The discharge tip of the ignition needle is aligned with the area of ​​the flame outlet 410 on the gas burner 400. When the user presses the button, an electric spark is generated at the end of the ignition needle to ignite the gas.

[0059] A metal heat spreader 600 is mounted at regular intervals directly above the gas burner 400. The heat spreader 600 has an inverted V-shaped cross-section, with the middle arching upwards and the sides sloping downwards. Multiple parallel, slightly upward-convex guide strips are formed on the two sloping surfaces of the heat spreader 600 facing the upper grill 700. One side of each guide strip has an opening. These guide strips help to disperse the heat transferred from the burner below, distributing it more evenly across the entire grill 700 area. Simultaneously, this structure also helps to guide dripping grease towards the edge of the heat spreader 600, reducing its direct dripping into the flame.

[0060] A removable baking rack 700 is placed above the heat spreader 600. The baking rack 700 is made of high-temperature resistant metal wire welded together to form a mesh structure, which is used to directly support food.

[0061] The oven body 100 is supported by two pairs of foldable support leg assemblies 800. Each pair of support leg assemblies 800 is mounted on connectors 200 on the left and right sides of the oven body 100. A pair of support leg assemblies 800 typically includes two metal support legs 810 and one or two lateral stabilizing rods 820 connecting the two support legs 810. The upper end of each support leg 810 is pivotally connected to the corresponding connector 200 via a pivot. The connector 200 is designed with angle limiting stops, which can be protrusions or grooves on the edge of the connector 200. When the support leg 810 is extended outward, specific parts of it abut against these stops, thereby limiting its extension angle within a preset range and preventing over-extension. When the oven is not in use, these support leg assemblies 800 can be folded inward and fitted against the side wall of the oven body 100.

[0062] To enhance ease of operation, a foldable side shelf 900 is pivotally connected to the connectors 200 on both sides of the oven body 100. Each shelf is connected to the connector 200 via a pivot and can be flipped down from a vertical storage state to a horizontal working state, forming a platform. Users can temporarily place ingredients, sauces, or grilling tools on this platform. The surface material of the shelf can be a perforated metal plate or a grid structure to reduce weight and facilitate cleaning.

[0063] In this embodiment, to enhance the stability of the outriggers in the extended state, a first set of pin holes is provided on the connector 200 near the pivot connection point of the outrigger rod 810. Simultaneously, on each outrigger rod 810 itself, when it is extended to a preset working angle, the second set of pin holes at the corresponding position aligns with the first set of pin holes. At this time, the user can manually insert a metal pin through both holes to lock the outrigger rod 810 to the connector 200, helping to prevent the outriggers from wobbling or retracting under force. This combination of angle limiting blocks and pin locking improves the stability of the barbecue grill during use.

[0064] Through the aforementioned structural components and their combination, the portable folding gas grill of this embodiment achieves the functions of portability, ease of setup, heating, and cleaning. The installation method of the gas burner 400 contributes to its reliable operation, while the locking mechanism of the support legs provides safety for user operation.

[0065] The portable folding gas grill of this embodiment integrates the grill body 100, the foldable support leg assembly 800 with angle limiting blocks and locking mechanisms, the foldable side shelf 900, the built-in gas burner 400 with a specific installation and fixing method, the piezoelectric igniter 500, the inverted V-shaped heat spreader 600, and the slide rail 310 type oil collection assembly 300 into a single design. This achieves a comprehensive effect of compact and portable structure, quick and stable deployment, stable combustion and uniform heating, safe and convenient operation, and relatively labor-saving cleaning and maintenance, providing users with a reliable and practical outdoor barbecue solution.

[0066] Example 2

[0067] This embodiment is based on the portable folding gas grill described in Embodiment 1, with a series of functional and detailed improvements. The basic structure and working principle shared with Embodiment 1 will not be repeated here; the focus is on describing the differentiated design and added features of this embodiment.

[0068] Along the rear long side of the lower furnace chamber 110, in addition to the existing hinges connecting to the upper furnace cover 120, a foldable windbreak and storage panel is additionally hinged. When not in use, this panel can be flat against the rear wall of the furnace body 100 or folded away for storage. When outdoor winds are strong, the user can flip this panel upwards, making it stand upright behind the furnace body 100, forming a windbreak barrier. This barrier reduces the disturbance of the burner flame by side and rear winds, contributing to stable combustion. To further stabilize the windbreak panel in its upright position, a movable, slender support rod is hinged to each of its left and right edges. The free ends of these support rods are designed with latches or hooks. When the windbreak panel is upright and the side storage platforms 900 on both sides are unfolded, the latches or hooks of the support rods can be engaged with the outer edge or specific grooves of the side storage platforms 900, thereby stabilizing the windbreak panel and potentially creating an additional storage surface.

[0069] This embodiment improves the structure of the side shelves 900 on both sides of the furnace body 100. Each side shelf 900 consists of a metal support frame and a movable base plate. The support frame itself is fixed with a metal wire mesh or a perforated grid plate to form a load-bearing surface. The movable base plate is a flat, thin metal plate or a heat-resistant plastic plate. The support frame and the movable base plate are both pivotally connected to the same pivot joint 200 connected to the furnace body 100, or each has an independent but coaxial pivot joint, and both can be independently rotated relative to the pivot joint 200.

[0070] Furthermore, a snap-fit ​​connection mechanism is designed between the movable base plate and the support frame. For example, the edges of the movable base plate can be machined with latches or flanges, while the corresponding edges of the support frame have matching slots or recesses. When a flat surface is needed, the movable base plate can be flipped to a position parallel to the support frame and pressed down, causing its latches to engage with the slots in the support frame, thus combining the two into a shelf. When ventilation, drainage, or easy cleaning is required, the movable base plate can be unlocked and removed, or flipped to a position that does not interfere with the use of the support frame. This design enhances the versatility and ease of cleaning of the Side Shelf 900.

[0071] Considering that the stability of the barbecue grill may be affected in outdoor environments, this embodiment includes a loop webbing, or ground stake rope, fixed at the bottom of each support leg 810 near its anti-slip pad. Users can carry additional ground stakes. When additional anchoring is needed, the stakes are driven into the ground, and the ground stake rope is then looped through or tightened to anchor the barbecue grill to the ground, helping to prevent tipping.

[0072] To meet the different grilling temperature requirements of various ingredients, this embodiment improves the installation method of the heat spreader 600, making its height or tilt angle adjustable. Specifically, one end of the heat spreader 600 is pivotally connected to a bracket fixed to the inner wall of the lower oven chamber 110. On the other side wall of the lower oven chamber 110, corresponding to the other end of the heat spreader 600, an adjustment opening is provided. A short threaded rod is fixedly connected to this end of the heat spreader 600, extending out of the oven chamber through the adjustment opening. A nut (serving as a nut connector 200) is screwed onto the rod outside the oven chamber. By rotating this external nut, the user can move the rod within the adjustment opening, thereby causing the entire heat spreader 600 to rotate around its pivot point, changing the distance or tilt angle between the heat spreader 600 and the gas burner 400 and the upper grill rack 700, thus adjusting the temperature and heat distribution of the grilling area.

[0073] As a supplement to the stability of the outrigger assembly 800 after deployment (or a solution coexisting with pin locking), this embodiment integrates one or more protruding spring devices near the pivot point of each outrigger rod 810 where it connects to the furnace body 100 connector 200. This is typically a small steel ball or round-headed pin with a spring inside, its head slightly protruding from the surface of the outrigger rod 810. Corresponding positioning holes are machined on the furnace body 100 connector 200 at positions corresponding to the outrigger rod 810 when deployed to a predetermined working angle. When the user deploys the outrigger rod 810 outwards, the protruding spring slides along the surface of the connector 200. Once the outrigger rod 810 reaches its working deployment angle, the protruding spring engages with the positioning hole under spring force, forming a positioning mechanism. This design is relatively convenient to operate and provides the user with feedback that the rod is locked in place. When folding is required, applying a certain force will disengage the protruding spring from the positioning hole.

[0074] To ensure that the unfolded side shelf 900 can support items without accidentally tipping over, this embodiment incorporates a pin locking mechanism. A third set of pin holes is pre-drilled on the connectors 200 on both sides of the furnace body 100, near the pivot connection point of the side shelf 900. Simultaneously, a fourth set of pin holes is correspondingly drilled on each side shelf 900 itself near its pivot connection point. When the user flips the side shelf 900 upwards to a horizontal working position, the third set of pin holes on the connectors 200 and the fourth set of pin holes on the side shelf 900 will be coaxially aligned. At this point, the user can insert a metal pin that passes through both holes to lock the side shelf 900 to the furnace body 100 connectors 200, improving its operational stability.

[0075] Based on Example 1, this embodiment improves the grill's adaptability and overall stability in varying outdoor environments by adding a windproof and storage dual-purpose plate, adopting a modular, snap-fit ​​side storage platform 900, equipping the legs with ground stake ropes, enabling height / angle adjustment of the heat spreader 600, introducing spring positioning for extended legs, and locking pins for the extended side storage platform 900. It also enhances the flexibility of heat control, ease of operation, and safety, optimizes the variability of storage space and ease of cleaning, providing users with a more comprehensive and superior outdoor grilling experience.
