Description

Technical Field

[0001] This utility model relates to the field of barbecue equipment technology, and in particular to a dual-purpose gas and charcoal barbecue grill. Background Technology

[0002] Barbecue, as a popular outdoor cooking method, is loved by consumers for its unique cooking experience and flavor, which has led to the emergence of many barbecue grills on the market.

[0003] Currently, most mainstream gas-charcoal dual-purpose barbecue grills on the market are gas-fired or gas-charcoal dual-purpose grills. They use metal burners and heat food by injecting high-temperature flames from burning propane or natural gas. Although they heat up quickly and are very easy to operate, they have two major drawbacks:

[0004] Firstly, gas and charcoal dual-purpose barbecue grills cannot produce a similar smoky aroma when burning, which greatly diminishes the flavor of the grilled food and makes it taste rather bland.

[0005] Secondly, existing gas / charcoal dual-purpose grills have a limited range of spit placement, with a fixed distance between the spit and the charcoal pan, lacking flexibility. In actual cooking, different types of food have varying grilling requirements: some foods need to be close to the heat source for rapid grilling, while others are better suited for slow grilling further away. However, the design of existing gas / charcoal dual-purpose grills clearly cannot meet these diverse grilling needs, which limits their applicability and cooking results to some extent.

[0006] Therefore, improvements to existing technologies are necessary. Utility Model Content

[0007] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a gas-charcoal dual-purpose barbecue grill, which solves the problems of existing gas-charcoal dual-purpose barbecue grills failing to produce smoky aromas, resulting in poor food flavor and texture, and the fixed distance between the grill fork and the charcoal pan failing to meet diverse grilling needs.

[0035] Reference Figures 1-4 An embodiment of this utility model provides a gas and charcoal dual-purpose barbecue grill, including a grill body, a roasting fork, a gas furnace assembly, and a charcoal basin 12 for holding charcoal blocks. The grill body includes two opposing side plates 40, with at least two sets of roller assemblies spaced apart along the height direction between the two side plates 40. The roasting fork is used to fix the food to be roasted. The axial direction of the roller assembly is parallel to the axial direction of the roasting fork, and the roasting fork is supported by any set of roller assemblies and can rotate on them. The charcoal basin 12 and the gas furnace assembly are both located inside the grill body, and the gas furnace assembly works in conjunction with the charcoal blocks to roast the food.

[0036] Both the gas stove assembly and the charcoal pan 12 are located within the main body of the oven. The gas stove assembly works in conjunction with the charcoal to roast food. The gas stove assembly can quickly provide a high-temperature flame for initial heating and rapid roasting of the food, ensuring roasting efficiency. Meanwhile, the charcoal continues to burn, releasing smoky aromas, which, together with the high-temperature flame of the gas stove assembly, allow the food to fully absorb the unique flavor of the charcoal fire while being roasted quickly. This collaborative working method retains the advantages of a gas / charcoal dual-purpose grill—fast heating and easy operation—while incorporating the flavor characteristics of charcoal grilling, effectively improving the flavor and texture of the roasted food. At least two sets of roller assemblies are spaced along the height between the two side panels 40. Users can place the skewers on either set of roller assemblies according to the needs of the food being roasted, meeting diverse roasting requirements. For example, for food that needs to be roasted quickly, the skewers can be placed on the roller assembly closer to the charcoal pan 12; while for food that needs to be roasted slowly, the skewers can be placed on the roller assembly farther from the charcoal pan 12.

[0037] According to some embodiments of the present invention, the gas furnace assembly includes a fixing frame 20, which is detachably installed between the two side plates 40 of the oven body. The fixing frame 20 is connected to a burner assembly on the side facing the roasting fork. The burner assembly is connected to a gas supply pipe assembly, and a main control valve assembly is provided on the gas supply pipe assembly.

[0038] According to some embodiments of the present invention, the burner assembly includes a first burner 21 and a second burner 22, the gas supply pipe assembly includes a first gas supply pipe and a second gas supply pipe, and the main control valve assembly includes a first main control valve 23 and a second main control valve 24. The first gas supply pipe and the second gas supply pipe are respectively connected to the first burner 21 and the second burner 22. The first main control valve 23 is disposed on the first gas supply pipe, and the second main control valve 24 is disposed on the second gas supply pipe. The first main control valve 23 and the second main control valve 24 respectively adjust the heating power of the corresponding burner.

[0039] The fixed frame 20 is bolted to the side plate 40. When the gas / charcoal dual-purpose grill is needed, the main control valve assembly (first main control valve 23 and second main control valve 24) is opened, and gas is delivered to the burner assembly (first burner 21 and second burner 22) through the gas supply pipe assembly (first gas supply pipe and second gas supply pipe). The gas burns on the burner assembly, producing a high-temperature flame that heats the food fixed on the skewers. Because there are two burners (first burner 21 and second burner 22) and corresponding main control valves (first main control valve 23 and second main control valve 24), the user can independently adjust the heating power of each burner. This allows the gas / charcoal dual-purpose grill to flexibly adjust the heating method according to different types, sizes, and grilling needs, avoiding the situation where the food is burnt or undercooked. For example, for larger foods that need to be heated evenly, both burners can be turned on simultaneously and the same heating power can be maintained; for foods that need to be heated in specific areas, only one burner can be turned on or the power difference between the two burners can be adjusted.

[0040] According to some embodiments of the present invention, the gas and charcoal dual-purpose barbecue grill also includes a bottom frame 10, which abuts against the bottom surface of the gas stove assembly and is detachably installed between the two side plates 40 of the grill body by bolts. The top of the bottom frame 10 is open, and the side of the bottom frame 10 facing the roasting fork is hollow to accommodate the charcoal basin 12. The side wall of the bottom frame 10 is provided with an air inlet 11, and several air inlets 11 are distributed at intervals.

[0041] The base frame 10 provides a stable space for the charcoal brazier 12. The charcoal brazier 12 is placed inside the base frame 10. The open top of the base frame 10 facilitates the placement and removal of the charcoal brazier 12. Air inlets 11 are located on the side walls of the base frame 10. During grilling, outside air enters the base frame 10 through these air inlets 11, providing ample oxygen for the combustion of the charcoal. With sufficient oxygen, the charcoal burns fully, producing high temperatures and smoky aromas. These aromas diffuse directly upwards to the food, allowing it to fully absorb the smoky aromas and resulting in a more authentic charcoal grilling flavor. The spaced air inlets 11 create a reasonable airflow path, ensuring a more even distribution of smoke within the base frame 10, preventing areas from being too dense or too light, and guaranteeing a uniform smoking effect on the food.

[0042] According to some embodiments of the present invention, the gas and charcoal dual-purpose barbecue grill also includes a motor 43, and the side plates 40 are provided with through holes. The two ends of the roasting fork pass through the through holes respectively. The motor 43 is fixedly installed on the outside of the side plates 40, and its output end is connected to one end of the roasting fork. The motor 43 drives the roasting fork to rotate around its central axis.

[0043] When motor 43 is started, the output end of motor 43 drives the roasting fork to rotate, and the food skewered on the roasting fork can continuously change position. There is no need to frequently manually flip the food, which reduces the time and effort of manual operation, avoids local overheating or undercooling, and ensures that all parts of the food are heated evenly, resulting in more consistent taste and more even cooking.

[0044] According to some embodiments of the present invention, the roasting fork includes a fixing tube 50, roasting skewers 52 and at least one connecting block 51. The fixing tube 50 is connected to the output end of the motor 43, and the connecting block 51 is connected to the fixing tube 50 by bolts. A number of roasting skewers 52 are evenly spaced and fixedly arranged on the connecting block 51.

[0045] The grill fork uses a connecting block 51 connected to the fixing tube 50 by bolts, and several skewers 52 are evenly spaced and fixed to the connecting block 51. This modular design allows users to flexibly adjust the number and layout of the connecting blocks 51 and skewers 52 according to actual grilling needs. Whether it's a small family barbecue party where a small amount of delicate food needs to be grilled, or a large barbecue event where a large amount of food needs to be grilled simultaneously, different combinations of connecting blocks 51 and skewers 52 can be easily adapted to different grilling scenarios, improving the versatility and practicality of the gas and charcoal grill. Furthermore, if a component is damaged, such as a broken skewer 52 or a loose connecting block 51, the user can quickly replace the damaged part without needing extensive repairs to the entire grill fork, extending its lifespan and reducing operating costs.

[0046] According to some embodiments of the present invention, the roller assembly includes a first roller 44 and a second roller 45, the first roller 44 and the second roller 45 are respectively disposed on both sides of the fixed tube 50, and both are tangentially fitted to the fixed tube 50.

[0047] The first roller 44 and the second roller 45 effectively limit the radial wobble of the fixed tube 50 during rotation. This makes the rotisserie fork rotate more smoothly and steadily, avoiding problems such as food falling off or uneven roasting caused by wobble. Secondly, the first roller 44 and the second roller 45 reduce the direct friction between the fixed tube 50 and the side plate 40, reducing the wear rate of the fixed tube 50 and extending the service life of the rotisserie fork. At the same time, it reduces the noise generated by friction, improving the user comfort of the gas and charcoal grill.

[0048] According to some embodiments of the present invention, the gas and charcoal dual-purpose barbecue grill also includes a lid 30 and a hinge assembly 33. The two ends of the hinge assembly 33 are respectively connected to the lid 30 and the side plate 40. The lid 30 can rotate relative to the side plate 40. When the lid 30 is rotated to the closed position, its edge seals against the upper edge of the bottom frame 10. The bottom frame 10, the side plate 40, the lid 30 and the gas stove assembly enclose a cooking chamber, which is connected to the outside through the air inlet 11.

[0049] According to some embodiments of the present invention, the cover 30 is provided with an observation window and connected to a handle 32, and a transparent plate 31 is provided at the observation window.

[0050] The hinge assembly 33 connects the lid 30 and the side plate 40 at its two ends, allowing the lid 30 to rotate relative to the side plate 40. When preparing to grill, the lid 30 is rotated to the open position, making it easy to place the food to be grilled on the grill fork, as well as to add charcoal and light the fire.

[0051] Once the food is placed and the charcoal and gas stove components are activated, rotate the lid 30 to the closed position. At this point, the edge of the lid 30 seals against the upper edge of the base frame 10, and the base frame 10, side panels 40, lid 30, and gas stove components together form a relatively enclosed cooking chamber. The cooking chamber is connected to the outside environment through the air inlet 11, allowing outside air to enter and provide oxygen for the charcoal combustion while simultaneously carrying away exhaust gases. The lid 30 has an observation window with a handle 32 attached, and a transparent panel 31 is located at the observation window. During grilling, the user can observe the food's cooking progress through the transparent panel 31 without frequently opening the lid 30. The handle 32 facilitates opening and closing the lid 30, improving user comfort.

[0052] According to some embodiments of the present invention, the gas and charcoal dual-purpose barbecue grill also includes a caster wheel 42. The bottom of the support leg 41 of the side plate 40 is provided with an axially extending connecting cavity. The inner peripheral wall of the connecting cavity is provided with a first thread. The caster wheel 42 is connected to a fixed seat 46 on the side facing the support leg 41. The fixed seat 46 is provided with a second thread that matches the first thread. The caster wheel 42 is detachably installed on the bottom of the support leg 41 through the threaded engagement between the fixed seat 46 and the connecting cavity.

[0053] When assembling the gas / charcoal dual-purpose barbecue grill, align the mounting base 46 of the universal wheel 42 with the connecting cavity at the bottom of the support leg 41 on the side plate 40. Since the mounting base 46 has a second thread that matches the first thread on the inner circumferential wall of the connecting cavity, rotate the mounting base 46 to achieve threaded engagement with the connecting cavity. Continue rotating the mounting base 46 until the universal wheel 42 is securely installed at the bottom of the support leg 41, completing the installation process of the universal wheel 42. Because the universal wheel 42 has multi-directional rotation characteristics, users can easily push the gas / charcoal dual-purpose barbecue grill, moving it in different directions, facilitating position adjustments without strenuous handling, and greatly improving the flexibility of use.

[0054] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
