Description

Technical Field

[0001] This utility model relates to the field of oven equipment technology, and in particular to a smokeless barbecue oven. Background Technology

[0002] Barbecue, a long-standing and popular cooking method, is enjoyed by people for family gatherings, meals with friends, and outdoor picnics. The resulting food is crispy on the outside and tender on the inside, with an irresistible aroma that whets the appetite.

[0003] Current barbecue methods typically involve open flame grilling or electric grilling, with open flame grilling being favored by many for its unique flavor. However, when using open flame grilling, the heat source (such as charcoal, gas, or electric heating elements) is placed directly inside the grill, with a metal grill rack above. Under the high temperature of the food, oil and seasonings continuously drip onto the heat source. These dripping oils and sauces burn rapidly under the intense heat, producing not only large amounts of pungent smoke but also potent carcinogens such as benzopyrene and polycyclic aromatic hydrocarbons. This pollutes the environment and may harm the health of the grill operator and those around them. Long-term inhalation of such smoke may cause respiratory diseases and even increase the risk of cancer. Utility Model Content

[0018] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0019] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the technical solution of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] The present invention will be described below through several specific embodiments. To keep the following description of the embodiments of the present invention clear and concise, detailed descriptions of known functions and components may be omitted. When any component of an embodiment of the present invention appears in more than one drawing, the component may be represented by the same reference numerals in each drawing.

[0021] like Figure 1 and Figure 6 As shown, this utility model embodiment provides a smokeless barbecue grill, including: a grill body 1, multiple heat source racks 3 and an oil separator 4; the top of the grill body 1 is open; the multiple heat source racks 3 and the oil separator 4 are connected inside the grill body 1, and the oil separator 4 is detachably connected to the top of the heat source racks 3; the oil separator 4 includes multiple inclined oil guiding units 41, with longitudinal gaps formed between the multiple oil guiding units 41, and the covering surface formed by the multiple oil guiding units 41 covers the horizontal plane of the heat source racks 3, and an oil guiding groove is provided on the oil guiding unit 41, the oil guiding groove is inclined, and a first oil outlet 4104 is provided on the lower side of the oil guiding groove; the heat source racks 3 are provided with a second oil outlet 32, and the second oil outlet 32 ​​is located below the first oil outlet 4104.

[0022] Specifically, the oven body 1 is a square shell. When grilling, the grill rack 6 is placed above the oven body 1, and the skewers are placed on the grill rack 6 for grilling. The oil-separating layer 4 covers the entire heat source area.

[0023] This utility model provides a smokeless barbecue grill with optimized structure and convenient use, mainly composed of a grill body 1, support legs 2, a heat source rack 3, and an oil-separating layer 4. The top of the grill body 1 adopts an open design, which is convenient for placing food and observing the grilling status; the heat source rack 3 is set inside the grill body 1 and can be used with various heat sources such as charcoal, bamboo charcoal, and electric heating elements; the oil-separating layer 4 is installed on top of the heat source rack 3 in a detachable manner, which is convenient for daily cleaning and maintenance. The oil-separating layer 4 adopts a modular design, which consists of multiple oil-guiding units 41 arranged side by side, and the number of oil-guiding units 41 can be installed according to the size of the grill body 1.

[0024] Specifically, the second oil outlet 32 ​​is larger than the first oil outlet 4104.

[0025] Each oil guiding unit 41 is equipped with an oil guiding groove with varying heights. A first oil outlet 4104 is located on its lower side, and a corresponding second oil outlet 32 ​​is located below the first oil outlet 4104, ensuring that oil droplets can flow out automatically by gravity. The oil separator 4 covers the entire heat source area, ensuring that all falling oil droplets are effectively collected. This design achieves sufficient heat exchange while preventing oil droplets from dripping directly from the unit gaps to the heat source. During use, the generated grease first falls onto the surface of the oil guiding unit 41, then flows along the inclined oil guiding groove from the higher side to the lower side, and finally, the oil droplets pass sequentially through the first oil outlet 4104 and the second oil outlet 32 ​​to a location outside the heat source of the heat source frame 3. Specifically, a longitudinal gap is formed between adjacent oil-guiding units 41: the edges of each oil-guiding unit 41 have overlapping joints, meaning the upper end of the front oil-guiding unit 41 covers the lower end of the adjacent rear oil-guiding unit 41. This ensures a 3-8mm ventilation gap for even heat conduction and forms a continuous leak-proof covering surface, ensuring that all falling oil droplets are effectively collected. This design avoids the problem of oil dripping onto high-temperature heat sources and producing fumes, achieving smokeless grilling. This invention solves the problem of excessive fumes in traditional grilling, improving the user experience and environmental friendliness; the oil-separating layer 4 is removable for easy cleaning and storage; it is compatible with multiple heat sources, offering flexible use; the structure is simple and reliable, and the production cost is low. It is particularly suitable for outdoor camping, backyard parties, commercial catering, and other occasions.

[0026] Optional, see reference Figure 3 and Figure 5 The oil guiding unit 41 includes an oil receiving plate 410 and a first oil guiding plate 412. The two first oil guiding plates 412 are arranged symmetrically on the left and right and are inclined towards the center. The oil receiving plate 410 and the first oil guiding plate 412 are connected to form an oil guiding groove.

[0027] This invention provides an arrangement of an oil-separating layer 4. Two first oil-guiding plates 412 are symmetrically arranged and connected to an oil-receiving plate 410 to form two V-shaped oil-guiding channels. The first oil outlet 4104 of the two oil-guiding channels is located at the center. Multiple oil-guiding units 41 are arranged side-by-side to form the oil-separating layer 4. After the two first oil-guiding plates 412 catch the oil droplets, the droplets slide down under gravity to the first oil outlet 4104 at the bottom center of the oil-guiding unit 41. The first oil outlet 4104 is located in the middle of the oven body 1, suitable for situations where the grill rack 6 is wide and there are gaps in the middle of the heat source rack 3. The symmetrical structure effectively expands the oil-receiving area, ensuring that oil droplets dripping from the wide grill rack 6 are fully captured. The modular design of the multiple oil-guiding units 41 allows for flexible adaptation to oven bodies 1 of different sizes. This design not only achieves centralized collection of waste oil, preventing oil droplets from scattering and contaminating the heat source, but also prevents oil droplets from overflowing through the oil-guiding channels, significantly improving the convenience of cleaning and maintenance.

[0028] Or refer to Figure 6As shown, a single first oil guide plate 412 is arranged at an angle to form an oil guide unit 41 with an oil receiving plate 410. Multiple oil guide units 41 are arranged side by side. Oil droplets slide down to the first oil outlet 4104 at the bottom of the oil trough under the action of gravity. The first oil outlet 4104 is located on one side of the oven body 1 and is suitable for situations where the width of the baking rack 6 is short and there are gaps on both sides of the heat source rack 3.

[0029] Or refer to Figure 7 As shown, two first oil guide plates 412 are symmetrically connected to the oil receiving plate 410 to form an inverted V-shaped oil guiding unit 41. After the two first oil guide plates 412 catch the oil droplets, the oil droplets slide down under the action of gravity to the first oil outlets 4104 at both ends of the inverted V-shaped oil guiding unit 41. The first oil outlets 4104 are located on both sides of the oven body 1, which is suitable for situations where the width of the baking rack 6 is relatively wide and there are gaps on both sides of the heat source rack 3. Of course, the oil guiding unit 41 can also be arranged in other ways, and this utility model does not make any special limitations on this.

[0030] Or refer to Figure 8 As shown, the cross-section of the oil guiding unit 41 is arc-shaped, and the oil receiving plate 410 is S-shaped.

[0031] Or refer to Figure 9 As shown, the oil guiding unit 41 is formed by connecting an inclined oil receiving plate 410 and a vertical first oil guiding plate 412, without an oil guiding groove. Of course, the first oil guiding plate 412 can also be other structures, and this utility model does not impose any special limitations on it.

[0032] Optionally, in the vertical projection direction, the upper end of each oil receiving plate 410 coincides with the lower end of the adjacent oil receiving plate 410.

[0033] This arrangement ensures that the grease barrier 4 forms a continuous and uninterrupted anti-drip coverage, preventing grease from dripping directly from the unit joints to the heat source, and effectively reducing the generation of oil fumes.

[0034] In the above embodiment, grease may slide onto the back of the oil receiving plate 410 and then onto the heat source, forming fumes.

[0035] Therefore, this embodiment provides an improved method.

[0036] Optional, see reference Figure 6 The upper end of the oil receiving plate 410 is inclinedly connected to the second oil guide plate 414, and the angle between the second oil guide plate 414 and the oil receiving plate 410 is an acute angle.

[0037] The top of the oil receiving plate 410 is connected to a second oil guide plate 414 forming an acute angle with its long side. This guide plate directs dripping grease to the first oil guide plate 412 of the adjacent oil guiding unit 41 or to a location without a heat source. When multiple oil guiding units 41 are arranged together, the second oil guide plate 414 can guide the grease to the oil receiving plate 410 of the next oil guiding unit 41, ensuring that the grease flows along the preset V-shaped oil guiding groove path and is finally discharged from the first oil outlet 4104 in the middle. This design effectively prevents grease from sliding off the back of the oil receiving plate 410 to the heat source, avoiding the resulting oil fume problem, while also improving the reliability and cleanliness of the oil guiding unit 41.

[0038] This embodiment of the utility model improves the structure of the oven body 1, reduces the overlapping area between the heat source rack 3 and the baking rack 6, so that the oil guiding unit 41 only needs to cover the overlapping area between the heat source rack 3 and the baking rack 6, further reducing the number of oil guiding units 41.

[0039] Optional, see reference Figure 1 The furnace body 1 includes: a furnace frame 13, two side plates 14, two heat source boxes 15 and two connecting plates 16. The two heat source boxes 15 are symmetrically slidably connected inside the furnace frame 13. One side of each heat source box 15 is hinged to the corresponding side plate 14. The two connecting plates 16 are symmetrically connected to the two side plates 14. The heat source frame 3 is connected inside the heat source box 15. A third oil outlet 152 corresponding to the second oil outlet 32 ​​is opened on the heat source box 15.

[0040] This utility model embodiment provides a hinged connection method between the components of the furnace body 1. Specifically, the side plate 14 adopts an inclined design to optimize the structural layout. The connecting plate 16 has symmetrically arranged perforated ear plates on both sides, with a first insertion groove machined below each hole. The first end of the side plate 14 has multiple equidistantly arranged first hinge holes, and the second end is equipped with a rotating shaft. The rotating shaft also has second insertion grooves on both sides, and a rotatable connection is achieved through the rotating shaft and the ear holes on the ear plates. Simultaneously, one side of the heat source box 15 has multiple second hinge holes corresponding to the first end of the side plate 14. When the hinge shaft passes sequentially through the first hinge holes of the side plate 14 and the second hinge holes of the heat source box 15, the hinged assembly of the heat source box 15 and the side plate 14 is completed. The rotation angle between the heat source box 15 and the side plate 14 does not exceed 180°. In actual operation, by synchronously pushing the heat source boxes 15 on both sides to slide relative to each other, the hinged side plate 14 can be gradually adjusted from an initial inclined state to a vertical state. During this process, the connecting plate 16 is raised accordingly. After the side plate 14 is completely vertical, the connecting plate 16 is pulled out along the rotation axis, so that its first insertion slot is precisely aligned with the second insertion slots on both sides of the rotation axis and inserted and locked, thereby achieving a stable fixation of the side plate 14. This hinge mechanism realizes flexible adjustment and reliable positioning of the furnace structure through the linkage between the heat source box 15 and the side plate 14.

[0041] Furthermore, the furnace frame 13 is hollow in the middle, and the top of the vertical plates on both ends is fixed with limiting plates. One end of the limiting plate is placed inside the furnace frame 13, and the other end extends out of the furnace frame 13. The part placed inside the furnace frame 13 restricts the movement of the connecting plate 16 in the vertical direction, thereby restricting the movement of the heat source box 15.

[0042] Furthermore, this utility model provides a connection method between the side plate 14, the connecting plate 16, and the heat source box 15. The ear plate has threaded holes and is threaded with fixing bolts. When the side plate 14 is in an inclined state, the fixing bolts are tightened to prevent relative rotation between the side plate 14 and the connecting plate 16. When it is necessary to turn the side plate 14 into a vertical state, the fixing bolts are loosened, allowing rotation between the side plate 14 and the connecting plate 16. A handle is fixed to the outside of the heat source box 15 for easy pulling and deforming. Of course, there are other connection and deformation methods between them, which this utility model does not specifically limit.

[0043] Furthermore, the heat source box 15 has multiple ventilation openings on its outer side to facilitate the introduction of external oxygen into the heat source box 15, so that the heat source can burn completely.

[0044] The side plate 14 is arranged at an angle, and the front projection of the side plate 14 covers part of the heat source rack 3. There is no need to set the oil guiding unit 41 above the covered part. At the same time, there is no need to set the oil guiding unit 41 in the hollow part between the two heat source boxes 15. The oil droplets in the middle part drip directly into the water tank 5 below. Therefore, it is only necessary to set the oil guiding unit 41 above the part of the heat source rack 3 that is not covered by the projection of the side plate 14, further reducing the number of oil guiding units 41.

[0045] Optionally, this utility model embodiment provides another connection method between the components of the furnace body 1. Specifically, the side plate 14 is inclined and hinged to the heat source box 15. The side plate 14 is bent on both sides, and movable holes are opened on the bent plates on both sides. The movable holes are arc-shaped. Positioning pins are installed at both ends of the top of the connecting plate 16. In actual use, the connecting plate 16 is connected to the limiting plate of the furnace frame 13 by splicing. The positioning pins at both ends of the connecting plate 16 are slidably connected to the movable holes on the bent plates on both sides of the side plate 14. By synchronously pushing the heat source boxes 15 on both sides to slide relative to each other, the hinged side plate 14 can be gradually adjusted from the initial inclined state to the vertical state. This connection method realizes the flexible adjustment and reliable positioning of the furnace body structure through the linkage between the heat source box 15 and the side plate 14.

[0046] To facilitate quick installation and disassembly of the oil separator 4 while ensuring a stable connection of multiple oil guiding units 41, this invention further optimizes the fixing structure of the oil guiding units 41. Specifically, multiple fixing posts 413 are provided on both sides of the oil guiding unit 41, and two rows of parallel mounting holes matching the fixing posts 413 are correspondingly opened on the connecting plate 16. During installation, the fixing posts on the same side of the oil guiding unit 41 are staggered left and right, allowing the oil guiding unit 41 to maintain a certain tilt angle. This design enhances the stability of the overall structure. During installation, simply align the multiple fixing posts 413 of the oil guiding unit 41 with the mounting holes on the connecting plates 16 on both sides. This improvement not only increases the efficiency of installing and disassembling the oil separator 4 but also optimizes the oil guiding effect through the tilted overlap, ensuring that the grease can flow smoothly along the oil guiding groove to the first oil outlet 4104.

[0047] Optional, see reference Figure 10 The stove frame 13 has shelves 131 rotatably connected to both sides.

[0048] The grill rack 13 has lockable bidirectional rotating shafts on both sides to connect to shelves 131, supporting 180° horizontal rotation and 90° vertical folding. It can be unfolded during grilling to serve as a work platform for placing seasonings, oil brushes, and other items, or folded away for storage to save space. The shelf 131 features a non-slip textured surface and a partitioned design. The wet area has a leak-proof groove for sauce bottles, while the dry area is flat for tools. Hooks are also provided along the edges for hanging clips or gloves. It can be made of high-temperature resistant aluminum alloy or stainless steel and is equipped with a heat insulation plate to prevent heat conduction. It also features a child safety lock and a load-bearing warning label. It is easy to clean and maintain. Whether for home barbecues or outdoor camping, this design flexibly adapts to various usage scenarios, balancing safety, functionality, and space efficiency.

[0049] In the above-described embodiments of the utility model, the oil-separating layer 4 has a certain ventilation gap to transfer heat. However, some baked goods still require high heat to be roasted, so the distance between the heat source and the baked goods needs to be shortened. Therefore, this utility model embodiment provides an improved method.

[0050] Optional, see reference Figure 4 The heat source frame 3 is characterized by further including an adjustment tag 31, which is detachably connected to the lower end of the heat source frame 3. Multiple adjustment holes 12 matching the adjustment tag 31 are vertically opened on both sides of the heat source box 15. The adjustment tag 31 passes through the adjustment holes 12 to the outside of the heat source box 15.

[0051] Specifically, the lower end of the heat source rack 3 is provided with an adjustment tag 31 slot, the adjustment tag 31 can be inserted and fixed, and the handle of the adjustment tag 31 is made of a low thermal conductivity material.

[0052] To further improve the adjustability of the heat source rack 3, this invention adds adjustment tabs 31 at both ends of the heat source rack 3. Specifically, the adjustment tabs 31 are detachably connected to the lower end of the heat source rack 3, and multiple sets of adjustment holes 12 matching the adjustment tabs 31 are vertically opened at both ends of the heat source box. When adjusting the height of the heat source rack 3, the adjustment tabs 31 are extended through the corresponding adjustment holes 12 to the outside of the heat source box 15. By selecting and fixing the adjustment holes 12 at different heights, the vertical position of the heat source rack 3 can be adjusted. This design allows users to quickly adjust the distance between the heat source rack 3 and the grill rack 6 according to cooking needs, thereby optimizing the heat radiation efficiency. At the same time, the external adjustment tabs 31 are intuitive and convenient to operate, and can complete the height adjustment, significantly improving the practicality of the equipment and the user experience. Furthermore, the detachable adjustment tabs 31 can be removed when adjustment is not needed to prevent heat from the heat source rack 3 from being transferred to the adjustment tabs 31, causing them to overheat and burn the user.

[0053] Furthermore, an adjustment hole 12 (not shown in the figure) is also provided on the side plate 14. When the side plate 14 is vertical and the distance between the heat source and the grill 6 is far, the heat source rack 3 can be adjusted to the adjustment hole 12 on the side plate 14 and fixed.

[0054] In the above embodiment, the oil guide groove directs the grease to the outside of the heat source frame 3, that is, the bottom of the furnace frame 13. This causes the grease to accumulate at the bottom of the furnace frame 13, making it difficult to clean.

[0055] Therefore, this embodiment provides an improved method.

[0056] Optional, see reference Figure 10 It also includes a water tank 5, which is located below the heat source rack 3.

[0057] Specifically, the furnace frame 13 has a water tank 5, and plates are fixed around the upper surface of the water tank 5 to support the heat source box 15 and allow the heat source box 15 to slide.

[0058] This invention further optimizes grease collection by adding a water tank 5 inside the grill frame 13. The water tank 5 is fixedly installed directly below the first oil outlet 4104, the second oil outlet 32, and the third oil outlet 152 of the oil guide channel. Its width is designed to completely cover the width of the third oil outlet 152, ensuring complete collection of the discharged grease. Before use, an appropriate amount of water can be injected into the water tank 5 to form a water seal. During operation, the grease flows out along the oil guide channel and falls directly into the water tank 5, where it quickly cools and solidifies upon contact with water, preventing grease evaporation and odor. Cleaning is simple; just pour out the condensed grease. The water seal effectively blocks grease evaporation, reducing the amount of smoke generated. The widened design of the water tank 5 ensures complete oil collection, and the detachable structure facilitates cleaning and maintenance. It is particularly suitable for long-term grilling or commercial use, maintaining a clean environment while significantly reducing maintenance difficulty.

[0059] In the above embodiments, it is mostly used for grilling skewers or other small grilled items. In actual use, it may be necessary to grill some large grilled items, such as lamb legs.

[0060] Therefore, this embodiment provides an improved method.

[0061] Optional, see reference Figure 1 and Figure 11 It also includes a rotating grill 7, which is rotatably connected to the top of the oven body 1.

[0062] Specifically, this utility model embodiment illustrates a connection method between a rotating grill 7 and a stove frame 13. The rotating grill 7 includes two plug-in plates 71 and a rotating frame 72. The rotating frame 72 is rotatably connected between the two plug-in plates 71. The plug-in plates 71 are provided with grooves 711, which are inserted into and cooperate with the side wall of the stove frame 13. There are many other connection methods for the rotating grill 7, which will not be listed here.

[0063] To accommodate the baking needs of large items, this invention adds a rotating grill 7 to the existing structure. The rotating grill 7 is detachably installed on top of the oven body 1 and consists of two insertion plates 71 and a central rotating frame 72. The rotating frame 72 is rotatably connected between the two insertion plates 71 via a bearing structure, achieving a uniform 15° rotation. The insertion plates 71 have special grooves 711 that precisely engage with the limiting plates on the side wall of the oven body 1, ensuring stable installation. During use, simply align the grooves 711 of the insertion plates 71 with the corresponding positions on the side wall of the oven body 1 for quick installation; disassembly is done by reversing the process. This modular design retains the original cooking function for small items while expanding support for larger ingredients through the detachable rotating grill 7. The rotating grilling method ensures more even heating of the food and avoids the hassle of manual flipping. Specifically, the connection between the rotating frame 72 and the plug-in plate 71 uses a high-temperature resistant bearing to ensure reliability during long-term rotation. The groove 711 of the plug-in plate 71 ensures stable installation while facilitating one-handed disassembly. Furthermore, the plug-in plate 71 is equipped with a motor and a rotating handle on both sides, allowing for motor-driven rotation or hand-cranked rotation. This improvement significantly enhances the versatility of the equipment's cooking functions, meeting users' baking needs for ingredients of different sizes.

[0064] Optional, see reference Figure 2 and Figure 3 It also includes two support legs 2, which are rotatably connected to both ends of the furnace body 1.

[0065] To further enhance the portability and flexibility of the equipment, this invention adds rotatable support legs 2 to both ends of the oven body 1. Specifically, the two support legs 2 are rotatably connected to both ends of the oven body 1 via a hinge mechanism. They can be unfolded in use to stably support the entire oven body 1, or folded against the side wall of the oven body 1 in the storage state, significantly reducing space occupation. This design is particularly suitable for mobile use scenarios such as outdoor grilling, allowing operators to quickly unfold or fold the support legs 2 as needed. The rotatable connection of the support legs 2 uses a high-temperature resistant metal pin with a limiting groove structure, ensuring both stability when unfolded and free rotation. Furthermore, the bottom of the support legs 2 is equipped with anti-slip rubber pads, providing reliable support even on wet or slippery surfaces. This improvement, while maintaining the original cooking functions, significantly enhances the portability and environmental adaptability of the equipment, making the overall structure more complete.
