Description

Technical Field

[0001] The invention relates to the technical field of food processing, in particular to a smokeless, environmentally friendly and energy-saving barbecue oven. Background Art

[0002] With the improvement of people's living standards, barbecue has become a popular form of leisure and entertainment and has been widely used in outdoor picnics, camping and other activities. Traditional barbecue grills will produce a lot of smoke and harmful gases during use, which not only pollutes the environment but also harms human health. In order to solve the problems of traditional barbecue grills, people have begun to develop smokeless, environmentally friendly and energy-saving barbecue grills. This type of barbecue grill uses advanced technology and materials, which can effectively reduce the emission of smoke and harmful gases, while improving energy utilization efficiency and reducing barbecue costs.

[0003] There are still many inconveniences in the use of current equipment;

[0004] The specific defects are as follows:

[0005] Firstly, during the barbecue process, due to the flow of people around the barbecue grill, the coal box inside the barbecue grill will be affected by external forces, such as the collision between the barbecue grill and people, the uneven placement of the barbecue grill, etc., which will cause the coal box to move or tilt inside the barbecue grill. The change of the position of the coal box during the barbecue process will affect the burning speed and temperature of the coal, and then the flame temperature will be too high or insufficient, resulting in poor barbecue effect, or even burnt or undercooked. In addition, a cinder box is provided at the bottom of the coal box. The change of the position of the coal box will cause the cinders inside the coal box to be unable to fall into the cinder box in a concentrated manner, but will be scattered inside the barbecue grill, causing inconvenience to the subsequent cleaning of the inside of the barbecue grill.

[0006] Secondly, an appropriate amount of air entering the barbecue grill can promote the full combustion of coal and improve combustion efficiency. However, if the damper is too small, the amount of air entering the barbecue grill is insufficient, and the fuel cannot be fully burned, resulting in slow combustion, uneven temperature and increased smoke emissions. When the damper is too large, too much air enters the barbecue grill, causing the coal to burn too quickly and the temperature to be too high. The existing side-drawn damper is relatively troublesome to adjust, requiring the user to reach out to the side of the barbecue grill to operate, which is not very convenient. In addition, the side-drawn damper is adjusted by pushing, pulling or sliding, and its adjustment range is relatively large, making it difficult to achieve fine adjustment, resulting in problems such as unstable fire and uneven temperature.

[0007] Therefore, the present invention proposes a smokeless, environmentally friendly and energy-saving barbecue grill to make up for and improve the deficiencies of the prior art. Summary of the invention

[0024] (III) Beneficial effects

[0025] The smokeless, environmentally friendly and energy-saving barbecue grill provided by the present invention has the following beneficial effects:

[0026] 1. Through the coordinated use of the coal box and the limiting mechanism, when the barbecue grill needs to be used and the coal box needs to be placed inside the inclined surface of the outer frame, the movable block is fixed with the fixed block to limit the position of the coal box, thereby solving the problem that the position of the coal box is easily changed by external influences. By limiting the position of the coal box, the coal box can be prevented from accidentally moving during the barbecue process, thereby ensuring that the firepower is always in a stable state during the barbecue process, thereby ensuring the effect and quality of the barbecue, and the coal box and the cinder box are in an aligned state, reducing the sparks and ashes generated during the coal combustion process from splashing into the surrounding environment, improving the safety of the barbecue, and facilitating the subsequent cleaning of the cinders.

[0027] 2. Through the coordinated use of the coal box and the adjustment structure, when the coal fire inside the coal box is too strong or insufficient, and the size of the barbecue grill air outlet needs to be adjusted, the No. 2 knob is manually twisted to increase the rotation angle of the bottom plate, and the side length of the equilateral hexagonal channel composed of multiple covering panels increases, thereby increasing the air outlet area and solving the problem of inconvenient air door adjustment. The knob-type air door can adjust the air volume by rotation, and the operation is relatively simple and intuitive. Users can more easily control the opening and closing degree of the air door. The size of the air outlet is easy to adjust, and the air flow in the barbecue grill can be controlled, thereby controlling the heat, which helps to ensure that the food is evenly grilled and will not be burnt or undercooked. In addition, the knob-type air door can provide more precise air volume adjustment than the side-drawn air door, and users can more accurately control the amount of air entering the barbecue grill, thereby better controlling the temperature and effect of the barbecue.

[0028] 3. Through the coordinated use of the outer frame and the protective mechanism, when the barbecue grill is fixed, the universal wheel is limited by the foot-operated brake. When the ground on which the barbecue grill is placed is uneven, the height of the universal wheel needs to be adjusted to ensure the stability and balance of the barbecue grill. The rising rod is manually pushed to drive the connecting push rod to slide downward. The connecting push rod slides downward, and then drives the universal wheel to slide downward, so that the universal wheel is more closely fitted to the ground, so that the barbecue grill is in a horizontal state, which solves the problem that the barbecue grill cannot adapt to different ground heights and the barbecue grill is tilted. By adjusting the height of the universal wheel, the barbecue grill can adapt to uneven ground, ensuring the stability and safety height of the barbecue grill, and the adjustable function further enhances the practicality of the barbecue grill, because it allows the user to adjust the height of the barbecue grill as needed to adapt to different terrains or usage scenarios.

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] refer to Figures 1 to 12 A smokeless, environmentally friendly and energy-saving barbecue grill according to a preferred embodiment of the present invention will be described in detail below. A smokeless, environmentally friendly and energy-saving barbecue grill comprises an outer frame 1, and a coal box 2 is slidably connected to the inner part of the outer frame 1. Figure 2 In the embodiment, a 45-degree angled bevel block is arranged on the top of the outer frame 1, a coal box 2 is located below the inner wall of the bevel block of the outer frame 1, the width of the bevel block on the top of the outer frame 1 is 30 centimeters, and the coal box 2 is located 25 centimeters deep inside the bevel block on the top of the outer frame 1. The bevel block adopts a 45-degree angle so that the charcoal fire in the coal box 2 inside the block can be centrally heated, so that the food can be heated more evenly and the efficiency of baking can be improved. A limiting mechanism 3 for fixing the coal box 2 is arranged inside the outer frame 1, an adjusting structure 4 for adjusting the size of the air outlet of the barbecue grill is arranged inside the outer frame 1, and a protective mechanism 5 for adjusting the height of the barbecue grill is arranged inside the outer frame 1;

[0048] The limiting mechanism 3 includes a central clamping shaft 319 for limiting the position of the coal box 2;

[0049] The regulating structure 4 includes a sealing panel 416 for sealing the air outlet;

[0050] The protection mechanism 5 includes a retracting rod 512 for adjusting the slope of the barbecue oven.

[0051] like Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, Figure 6In the embodiment, the limiting mechanism 3 includes a first knob 311, which is rotatably connected to the inside of the outer frame 1. The surface of the coal box 2 is fixedly connected with a movable block 313, and the inside of the outer frame 1 is fixedly connected with a fixed block 312. When the barbecue oven is used and the coal box 2 needs to be placed inside the inclined surface of the outer frame 1, the movable block 313 enters the inside of the fixed block 312 under manual push, as shown in FIG. Figure 3 and Figure 4 In the embodiment, the interior of the fixed block 312 and the movable block 313 are fixedly connected with the abutment panel 3110 and the limiting circular frame 317, and the central clamping shaft 319 is rotatably connected to the interior of the limiting circular frame 317 and the shifting rod 318. The central clamping shaft 319 contacts the abutment panel 3110 inside the fixed block 312. Since the surface of the abutment panel 3110 is an inclined surface, the central clamping shaft 319 rotates under the push of the inclined surface of the abutment panel 3110. Figure 4 The surfaces of the center clamping shaft 319 are fixedly connected with the shifting rod 318, the surfaces of the fixed clamping block 312 and the shifting rod 318 are fixedly connected with the pulling clamping block 314, the interior of the pulling clamping block 314 is fixedly connected with a movable hook 315, and the two movable hooks 315 are fixedly connected with a limiting spring 316, and the center clamping shaft 319 rotates under the push of the inclined surface of the abutment panel 3110, and the limiting spring 316 is stretched under the pull of the clamping block 314 on the surface of the shifting rod 318, and the No. 1 knob 311 is fixedly connected with the center clamping shaft 319 inside the fixed clamping block 312, the limiting circular frame 317 is semicircular, and the surfaces of the two limiting circular frames 317 fit together, the abutment panel 3110 is U-shaped, and one end of the abutment panel 3110 is set to an inclined surface. As the coal box 2 completely reaches the combustion position, the fixed clamping block 312 fits with the surface of the fixed clamping block 312, and the fixed clamping The block 312 completely overlaps with the semicircular part of the limiting circular frame 317 inside the movable clamping block 313, thereby forming a circular groove, and the two center clamping shafts 319 are rotatably connected to the inside of the circular groove formed by the two limiting circular frames 317, and the two center clamping shafts 319 lose the restriction of the abutment panel 3110, and the limiting spring 316 contracts to pull the two center clamping shafts 319 to rotate inside the limiting circular frame 317 through the pulling clamping block 314 on the surface of the shift rod 318. Since the circular groove formed by the limiting circular frame 317 and the opening of the circular axis formed by the center clamping shaft 319 are staggered, the movable clamping block 313 and the fixed clamping block 312 are fixed, and then the coal box 2 is limited. Since a cinder box is provided at the bottom of the coal box 2, the position of the coal box 2 is limited to ensure that the cinders inside the coal box 2 fall into the cinder box accurately and concentratedly, which is convenient for the subsequent cleaning of the internal hygiene of the barbecue oven.

[0052] like Figure 7 , Figure 8 and Fig. 9 As shown, Figure 7In the embodiment, the adjustment structure 4 includes a second knob 411, which is rotatably connected to the inside of the outer frame 1, and the inside of the outer frame 1 is rotatably connected to a power gear 417, and the inside of the outer frame 1 is rotatably connected to a rotating bottom plate 412, and the power gear 417 is meshed with the rotating bottom plate 412. The second knob 411 and the power gear 417 are fixedly connected. When the coal fire inside the coal box 2 is too large or insufficient, and the size of the barbecue grill air outlet needs to be adjusted, the second knob 411 is manually twisted to drive the power gear 417 to rotate. Since the power gear 417 is meshed with the rotating bottom plate 412, the power gear 417 rotates to drive the rotating bottom plate 412 to rotate. Figure 8 In the embodiment, a rotating bottom plate 412 is provided on the surface of the rotating bottom plate 412, and the rotating bottom plate 412 is an equilateral hexagon. A fixed top plate 413 is fixedly connected to the inside of the outer frame 1, and six limit abutment plates 414 are fixedly connected to the surface of the fixed top plate 413. An adjustment groove is provided on the surface of the limit abutment plates 414. Six sealing panels 416 are slidably connected to the rotating bottom plate 412, and the inside of the sealing panels 416 are fixedly connected to an adjustment slide shaft 415. One end of the adjustment slide shaft 415 is slidably connected to the inside of the limit card slot 418, and one end of the adjustment slide shaft 415 is slidably connected to the limit abutment plate 416. 14, the rotating base plate 412 rotates, and the limit card groove 418 on the surface of the rotating base plate 412 is an equilateral hexagon. Since the adjustment slide shaft 415 inside the cover panel 416 is slidably connected to the inside of the limit card groove 418 on the surface of the rotating base plate 412, the rotating base plate 412 rotates, and the cover panel 416 slides under the drive of the adjustment slide shaft 415. Since one end of the adjustment slide shaft 415 slides inside the adjustment groove inside the limit plate 414, and since the adjustment groove inside the limit plate 414 is inclined, the cover panel 416 slides in the limit card groove 418 on the surface of the rotating base plate 412. Fig. 9 In the figure, the sides of multiple covering panels 416 are fitted with each other, the side length of the limiting slot 418 is equal to the length of the adjustment slot on the surface of the limiting abutment 414, and the limiting abutment 414 tilts and slides under the restriction of the adjustment slide shaft 415. Each covering panel 416 sliding on the surface of the rotating bottom plate 412 slides in contact with the surface of the adjacent covering panel 416. During the tilting and sliding process of the adjacent covering panels 416, as the degree of sliding of the covering panels 416 on the surface of the adjacent covering panels 416 increases, equilateral hexagonal channels are formed inside the multiple covering panels 416, and as the rotation angle of the rotating bottom plate 412 increases, the side length of the equilateral hexagonal channels formed inside the multiple covering panels 416 increases, thereby increasing the air outlet area.

[0053] like Fig.10 , Fig.11 and Fig.12 As shown, Fig.10In the embodiment, the protection mechanism 5 includes a side block 511, the side block 511 is fixedly connected to the surface of the outer frame 1, the folding rod 512 is slidably connected to the inside of the side block 511, the inside of the side block 511 is slidably connected to the rising rod 513, the folding rod 512 and the rising rod 513 are both L-shaped, the inside of the side block 511 is fixedly connected to the second spring 5110, the second spring 5110 is fixedly connected to the bottom of the folding rod 512 and the rising rod 513, the inside of the side block 511 is slidably connected to the connecting push rod 5111, and the lower surface of the connecting push rod 5111 is fixed A universal wheel with a pedal brake is connected. When the barbecue grill is fixed, the universal wheel is limited by the pedal brake. When the ground on which the barbecue grill is placed is uneven, the height of the universal wheel needs to be adjusted to ensure the stability and balance of the barbecue grill. The rising rod 513 is manually pushed, and the rising rod 513 slides downward. The second spring 5110 is compressed under the push of the rising rod 513. Since the toggle block 515 is located inside the adjacent tooth block on the surface of the power side plate 516, the rising rod 513 slides and drives the surface toggle block 515 to push the power side plate 516 to rotate. Fig.11In the embodiment, the power side plate 516 is located inside the rotation path of the toggle block 515, the spring paddle 514 is equal to the power side plate 516 in thickness, and the spring paddle 514 and the power side plate 516 are both half the thickness of the toggle block 515, the spring paddle 514 is located inside the rotation path of the toggle block 515, the folding rod 512 and the rising rod 513 are symmetrically arranged with the limit block 518 as the axis, the surfaces of the folding rod 512 and the rising rod 513 are fixedly connected with the spring paddle 514, and the folding rod 512 and The surface of the rising rod 513 is rotatably connected to the toggle block 515, the surface of the spring toggle 514 is in contact with the surface of the toggle block 515, the inner part of the side block 511 is rotatably connected to the central connecting shaft 517, one end of the central connecting shaft 517 is fixedly connected to the power side plate 516, the toggle blocks 515 are slidably connected to the inner part of the adjacent tooth block on the surface of the power side plate 516, the inner part of the side block 511 is fixedly connected to the limit frame, the inner part of the limit frame of the side block 511 is fixedly connected to the first spring 519, and the side block 51 The limiting block 518 is slidably connected to the inside of the tooth block adjacent to the surface of the power side plate 516, and the toggle block 515 compresses the spring paddle 514 so that the spring paddle 514 is retracted. When the power side plate 516 is pushed by the toggle block 515 to rotate, since the limiting block 518 is located inside the tooth block adjacent to the surface of the power side plate 516, the power side plate 516 rotates to push the limiting block 518 to slide. The spring 519 is compressed under the push of the limit block 518. When the power side plate 516 rotates under the continuous push of the toggle block 515, the toggle block 515 is located inside the adjacent tooth block of the power side plate 516, and the toggle block 515 does not contact the tooth block of the power side plate 516. The toggle block 515 will recover under the rebound effect of the spring paddle 514, and the limit block 518 will re-enter the rotation path of the power side plate 516 under the thrust of the spring 519, so as to limit the rotation of the power side plate 516. Fig.12 In the figure, one end of the central connecting shaft 517 is fixedly connected with a transmission gear 5112, and a tooth block is provided on the surface of the connecting push rod 5111. The transmission gear 5112 is meshed with the tooth block on the surface of the connecting push rod 5111. When the power side plate 516 rotates, the transmission gear 5112 rotates with the power side plate 516 through the central connecting shaft 517. Due to the meshing between the tooth block on the surface of the connecting push rod 5111 and the transmission gear 5112, the connecting push rod 5111 is driven to slide downward, and the connecting push rod 5111 slides downward, thereby driving the universal wheel to slide downward.

[0054] The following is the entire working process and working principle of the above embodiment:

[0055] Initially: the center clamping shaft 319 is in an inclined state due to the pull of the limit spring 316 on the shift rod 318, the limit spring 316 is in an uncompressed state, the adjusting slide shaft 415 is in the end of the adjusting groove inside the limit abutment plate 414 away from the fixed top plate 413, the air outlet formed by the multiple sealing panels 416 is in a closed state, the spring paddle 514 is in an uncompressed state, the surface of the universal wheel at the bottom of the connecting push rod 5111 is in contact with the lower surface of the side block 511, and the toggle block 515 and the limit clamping block 518 are located inside the tooth block adjacent to the surface of the power side plate 516.

[0056] During operation: when the barbecue grill is used and the coal box 2 needs to be placed inside the inclined surface of the outer frame 1, the movable clamping block 313 enters the fixed clamping block 312 under manual push, and the central clamping shaft 319 contacts the inner abutment panel 3110 of the fixed clamping block 312. Since the surface of the abutment panel 3110 is an inclined surface, the central clamping shaft 319 rotates under the push of the inclined surface of the abutment panel 3110, and the limiting spring 316 is stretched under the pull of the clamping block 314 on the surface of the shift rod 318. Since the flat part of the central clamping shaft 319 fits with the inclined part of the abutment panel 3110, as the internal limiting circular frame 317 of the movable clamping block 313 continues to penetrate into the fixed clamping block 312, the central clamping shaft 319 inside the limiting circular frame 317 gradually changes from an inclined state to a horizontal state;

[0057] At the same time, when the abutment panel 3110 inside the movable block 313 enters the fixed block 312, the abutment panel 3110 inside the movable block 313 pushes the central clamping shaft 319 inside the fixed block 312 to also become horizontal, and the movable block 313 continues to enter the fixed block 312. As the coal box 2 completely reaches the combustion position, the fixed block 312 fits with the surface of the fixed block 312, and the semicircular part of the limiting circular frame 317 inside the fixed block 312 and the movable block 313 completely overlaps, thereby forming a circular groove, and the two central clamping shafts 319 are rotatably connected to the circular groove formed by the two limiting circular frames 317, and the two central clamping shafts 319 lose the restriction of the abutment panel 3110, and the limiting spring 316 contracts to thereby pull the coal box 2 through the surface of the shift rod 318. The movable clamping block 314 pulls the two central clamping shafts 319 to rotate inside the limiting circular frame 317. Since the circular groove formed by the limiting circular frame 317 and the opening of the circular axis formed by the central clamping shaft 319 are staggered, the movable clamping block 313 and the fixed clamping block 312 are fixed, thereby limiting the position of the coal box 2, solving the problem that the position of the coal box 2 is easily affected by external factors and causing changes. By limiting the position of the coal box 2, the coal box 2 can be prevented from accidentally moving during the barbecue process, thereby ensuring that the firepower is always in a stable state during the barbecue process, thereby ensuring the barbecue effect and quality, and the coal box 2 is aligned with the coal slag box, reducing the sparks and ashes generated during the coal combustion process from splashing into the surrounding environment, improving the safety of barbecue, and facilitating the subsequent cleaning of the coal slag.

[0058] Furthermore, when the coal fire inside the coal box 2 is too strong or insufficient, and the size of the barbecue grill air outlet needs to be adjusted, the second knob 411 is manually twisted to drive the power gear 417 to rotate. Since the power gear 417 is meshed with the rotating bottom plate 412, the power gear 417 rotates to drive the rotating bottom plate 412 to rotate. The rotating bottom plate 412 rotates. The limit slot 418 on the surface of the rotating bottom plate 412 is an equilateral hexagon. Since the sliding shaft 416 is adjusted inside the sealing panel 416, The cover panel 416 is slidably connected to the inside of the limit card slot 418 on the surface of the rotating bottom plate 412. The rotating bottom plate 412 rotates, and the cover panel 416 slides under the drive of the adjustment slide shaft 415. Since one end of the adjustment slide shaft 415 slides inside the adjustment slot inside the limit plate 414, and since the adjustment slot inside the limit plate 414 is inclined, the cover panel 416 slides in the limit card slot 418 on the surface of the rotating bottom plate 412, and slides obliquely under the restriction of the limit plate 414 on the adjustment slide shaft 415, and slides on the rotating bottom plate 412. Each sealing panel 416 on the surface of the movable bottom plate 412 slides in contact with the surface of the adjacent sealing panel 416. During the tilting and sliding process of the adjacent sealing panels 416, as the sealing panels 416 slide on the surfaces of the adjacent sealing panels 416 to an increasing extent, an equilateral hexagonal channel is formed inside the plurality of sealing panels 416. Moreover, as the rotation angle of the rotating bottom plate 412 increases, the side length of the equilateral hexagonal channel formed inside the plurality of sealing panels 416 increases, thereby increasing the air outlet area and solving the problem of inconvenient air door adjustment. The knob-type air door can adjust the air volume by rotation, and the operation is relatively simple and intuitive. The user can more easily control the opening and closing degree of the air door. The size of the air outlet is easy to adjust, and the air flow in the barbecue grill can be controlled, thereby controlling the heat, helping to ensure that the food is evenly grilled without being burnt or undercooked. Moreover, the knob-type air door can provide more precise air volume adjustment than the side-drawn air door, and the user can more accurately control the amount of air entering the barbecue grill, thereby better controlling the temperature and effect of the barbecue.

[0059] Furthermore, when the barbecue grill is fixed, the universal wheel is limited by the pedal brake. When the ground on which the barbecue grill is placed is uneven, the height of the universal wheel needs to be adjusted to ensure the stability and balance of the barbecue grill. The rising rod 513 is manually pushed, and the rising rod 513 slides downward. The second spring 5110 is compressed under the push of the rising rod 513. Since the toggle block 515 is located inside the adjacent tooth block on the surface of the power side plate 516, the rising rod 513 slides and drives the surface toggle block 515 to push the power side plate 516 to rotate, and The toggle block 515 compresses the spring paddle 514 so that the spring paddle 514 is retracted. When the power side plate 516 rotates under the push of the toggle block 515, since the limit block 518 is located inside the tooth block adjacent to the surface of the power side plate 516, the power side plate 516 rotates to push the limit block 518 to slide. The first spring 519 is compressed under the push of the limit block 518. When the power side plate 516 rotates under the continuous push of the toggle block 515, the toggle block 515 is located inside the tooth block adjacent to the power side plate 516, and the toggle block 51 5 does not contact with the gear block of the power side plate 516, the toggle block 515 will recover under the rebound effect of the spring toggle 514, and the limit block 518 will re-enter the rotation path of the power side plate 516 under the thrust of the No. 1 spring 519 to limit the rotation of the power side plate 516. When the power side plate 516 rotates, the transmission gear 5112 rotates with the power side plate 516 through the central connecting shaft 517, and the connection push rod 5111 is driven to slide downward due to the meshing between the gear block on the surface of the connection push rod 5111 and the transmission gear 5112. The connecting push rod 5111 slides downward, thereby driving the universal wheel to slide downward, so that the universal wheel fits the ground more closely, thereby making the barbecue grill level, solving the problem that the barbecue grill cannot adapt to different ground heights and the barbecue grill is tilted. By adjusting the height of the universal wheel, the barbecue grill can adapt to uneven ground, ensuring the stability and safety height of the barbecue grill, and the adjustable function further enhances the practicality of the barbecue grill, because it allows the user to adjust the height of the barbecue grill as needed to adapt to different terrains or usage scenarios.
