Description

Technical Field

[0001] This application relates to the field of barbecue grill technology, and in particular to a barbecue grill shell structure and a barbecue grill using the same. Background Technology

[0002] A barbecue grill is a type of grilling equipment used to cook grilled foods such as lamb skewers and roasted meats. Barbecue grills can be divided into three types: charcoal grills, gas grills, and electric grills. Gas grills and electric grills are particularly popular because they produce no oil smoke and do not contaminate the food. Common types of barbecue grills on the market include apple-shaped grills, rectangular grills, and portable grills.

[0003] Most existing charcoal grills consist of a flat grill rack mounted on a support platform. Food is placed on the rack, and the support platform, located at the bottom of the rack, holds the charcoal. The food is then cooked on the rack. However, with this design, heat easily escapes outwards when food is placed on the rack, affecting the cooking time. Therefore, improvements are needed. Summary of the Invention

[0004] In order to improve the problem that heat easily evaporates to the outside during grilling, affecting the cooking time of food, the purpose of this application is to provide a grill shell structure and a grill using the same.

[0005] Firstly, the technical solution for the barbecue grill shell structure provided in this application is as follows:

[0006] A barbecue grill shell structure includes a base and a cover plate. The base has a housing cavity. The cover plate is hinged to the base via a hinge post. When the cover plate abuts against the base, it can form a sealed space for the housing cavity. The base has a vent hole, and a rotating plate is installed at the vent hole to adjust the opening and closing of the vent hole.

[0007] By adopting the above technical solution, when food is placed in the placement cavity of the base, the placement cavity can be sealed by the cover plate to temporarily enhance the grilling temperature of the food surface, so that the food can be cooked through quickly; the ventilation holes facilitate the flow of smoke inside the placement cavity to the outside, and the rotating plate is used to control the opening and closing of the ventilation holes. With this shell structure, most of the heat can be prevented from evaporating to the outside during grilling, which can speed up the cooking time of the food and make the process convenient to use.

[0008] Optionally, the placement cavity is provided with a first grill and a second grill, the first grill and the second grill are parallel vertically and are separated by a height distance, and the second grill is separated from the bottom of the base by a height distance.

[0009] By adopting the above technical solution, the second grill can be used to place charcoal, and the first grill can be used to place food. The second grill is positioned at a height distance from the bottom of the base, allowing waste residue from the charcoal to separate and fall to the bottom of the base during combustion, ensuring complete combustion. The height distance between the first and second grills allows the first grill to be installed horizontally after the charcoal is placed, facilitating food placement.

[0010] Secondly, the barbecue grill provided in this application adopts the following technical solution:

[0011] A barbecue grill, comprising the aforementioned barbecue grill shell structure, further comprising a support platform, wherein the barbecue grill shell is fixedly mounted on the support platform, and the support platform is provided with a rotating component and an air blowing component, wherein the rotating component is used to control the rotation of food on the grill, and the air blowing component is used to blow air into the placement cavity.

[0012] By adopting the above technical solution, the support platform is used to support the entire barbecue grill shell, the rotating component can control the rotation of the food on the grill, and speed up the cooking of the food; the air blowing component makes it easy to blow air into the placement cavity, which speeds up the burning speed of charcoal and also speeds up the cooking speed of the food, while also ensuring that the heat inside the placement cavity is evenly distributed.

[0013] Optionally, the rotating assembly includes a drive shaft, a first rotating shaft, a second rotating shaft, and a rotating column. The drive shaft, the first rotating shaft, and the second rotating shaft are all rotatably connected to the support platform. The drive shaft and the first rotating shaft are connected by a first conveyor belt. The first rotating shaft and the second rotating shaft are connected by a bevel gear. The second rotating shaft and the rotating column are connected by a second conveyor belt. The rotating column is rotatably connected to the base, and its end extends into the mounting cavity.

[0014] By adopting the above technical solution, the drive shaft controls the rotation of the first rotating shaft through the first conveyor belt, the first rotating shaft controls the rotation of the second rotating shaft through the bevel gear, the second rotating shaft controls the rotation of the rotating column through the second transmission belt, the rotating column is rotatably connected to the base, and its end extends into the placement cavity.

[0015] Optionally, a limiting hole is provided at the end of the rotating column within the mounting cavity.

[0016] By adopting the above technical solution and utilizing the limiting hole, once the food is skewered, one end of the skewer can rest against the limiting hole. When the rotating column rotates, it drives the skewer to rotate simultaneously, causing the food to turn over and speeding up the cooking time. The process does not require manual operation to turn the food over, thus avoiding localized burns to the fingers.

[0017] Optionally, multiple rotating columns are provided, and each rotating column is driven by a transmission component.

[0018] By adopting the above technical solution, multiple rotating columns are installed, facilitating the simultaneous rotation and flipping of multiple skewers of food, thus accelerating the grilling process. Each rotating column is connected by a meshing transmission mechanism, resulting in a simple and effective transmission process.

[0019] Optionally, a cam is provided on the first rotating shaft, and the air blowing assembly is movably connected to the cam. The air blowing assembly includes an air pump and a transmission rod. The air pump includes a sleeve and a plunger. The plunger is located inside the sleeve and slides linearly along the sleeve. The sleeve is located inside the mounting cavity and has multiple ports at its end, which are connected to the plunger. One end of the transmission rod is rotatably connected to the plunger, and the other end is rotatably connected to the cam.

[0020] By adopting the above technical solution, when the first rotating shaft rotates, the cam drives the plunger to move linearly along the inside of the sleeve via the transmission column. This allows air to enter the sleeve through the port. As the plunger slides back and forth, the air inside the sleeve is injected into the placement cavity through the port. At this time, the charcoal burns faster under the action of the airflow, and the food is cooked more easily. Simultaneously, the airflow through the port facilitates a uniform temperature distribution within the placement cavity, ensuring that all food is heated evenly. The air-blowing component does not require separate control; it can be synchronously driven by the rotating component, resulting in strong structural linkage and convenient operation.

[0021] Optionally, the cover plate is provided with a gripper.

[0022] By adopting the above technical solution, the gripper facilitates the opening and closing of the cover. When the cover is open, it facilitates the flow of smoke generated inside the cavity to the outside; when the cover is closed, it facilitates the temperature rise inside the cavity and increases the surface temperature of the food.

[0023] Optionally, the bottom of the support platform is provided with pulleys.

[0024] By adopting the above technical solution and using pulleys, the support platform can be easily moved, making it convenient to move the barbecue to different positions.

[0025] Optionally, a mounting plate is provided on the support platform.

[0026] By adopting the above technical solution, the mounting plate can be used to temporarily place food to be grilled or to serve it.

[0027] In summary, this application includes at least one of the following beneficial effects:

[0028] 1. When food is placed in the mounting cavity of the base, the mounting cavity can be sealed by the cover plate to temporarily enhance the grilling temperature of the food surface, so that the food can be cooked through quickly; the ventilation holes allow the smoke inside the mounting cavity to flow to the outside, and the rotating plate is used to control the opening and closing of the ventilation holes. This shell structure can prevent most of the heat from evaporating to the outside during grilling, which can speed up the cooking time of the food. The process is convenient to use and has strong overall practicality.

[0029] 2. Utilizing two grill racks: the second rack can be used to hold charcoal, and the first rack can be used to hold food. The second rack is positioned at a height difference from the bottom of the base, allowing ash to fall to the bottom of the base during combustion, ensuring complete burning of the charcoal. The height difference between the first and second racks also allows the first rack to be installed horizontally after the charcoal is placed, facilitating food placement.

[0030] 3. The rotating component can be used to control the rotation of food on the grill, which speeds up the cooking process; the air blowing component allows air to be blown into the cavity, which speeds up the burning of charcoal and the cooking of food, while also ensuring that the heat is evenly distributed inside the cavity; the air blowing component does not require separate control, as it can be driven synchronously by the rotating component, resulting in strong structural linkage and convenient operation.

[0040] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail below.

[0041] Example 1: A barbecue grill shell structure, referring to Figure 1 The device includes a base 100 and a cover plate 200. The cover plate 200 is rotatably connected to the base 100 via a hinge post 210. A mounting cavity 110 is provided within the mounting cavity. A first grill 120 and a second grill 130 are mounted within the mounting cavity. Both the first grill 120 and the second grill 130 are planar structures, and each has multiple through holes arranged in an array. The first grill 120 is located above the second grill 130. The base 100, located within the mounting cavity 110, is provided with a first support plate 121 for supporting the first grill 120 and a second support plate 131 for supporting the second grill 130. The first grill 120 can be used to place food, and the second grill 130 can be used to place charcoal. The second grill 130 is provided with a height distance from the bottom of the base 100, so that the ash can be separated and fall to the bottom of the base 100 during the burning of charcoal, which is conducive to the complete combustion of charcoal; the first grill 120 and the second grill 130 are provided with a height distance, so that the first grill 120 can be installed horizontally after the charcoal is placed, which is convenient for placing food.

[0042] Specifically, a handle 220 is provided on the cover plate 200 to facilitate the control of the cover plate 200 to flip along the hinge post 210. When the cover plate 200 abuts against the base 100 via the hinge post 210, the mounting cavity 110 forms a sealed space to temporarily enhance the grilling temperature of the food surface, facilitating rapid cooking. Ventilation holes 140 are provided on the left and right sides of the base 100, and a rotating plate 150 is installed at the ventilation hole 140. The rotating plate 150 is used to control the opening and closing of the ventilation hole 140. The ventilation hole 140 facilitates the flow of smoke from inside the mounting cavity 110 to the outside, while simultaneously reducing the temperature inside the mounting cavity 110. Utilizing this grill shell structure, most of the heat can be prevented from evaporating to the outside during grilling, thus accelerating the cooking time of the food.

[0043] The implementation principle of this application embodiment is as follows: food is placed on the first grill 120, and charcoal is placed on the second grill 130. When the cover plate 200 abuts against the base 100 through the hinge post 210, the placement cavity 110 forms a sealed space to temporarily enhance the grilling temperature of the food surface, so that the food can be cooked through quickly. The ventilation hole 140 facilitates the flow of smoke inside the placement cavity 110 to the outside, while reducing the temperature inside the placement cavity 110. The rotating plate 150 is used to control the opening and closing of the ventilation hole 140, or to control the opening flow of the ventilation hole 140, so as to better meet the temperature required by the food during the grilling process.

[0044] Example 2: Barbecue grill, including the aforementioned barbecue grill shell structure, refer to Figure 1 and Figure 2 The system also includes a support platform 300, on which the barbecue grill shell is welded and fixedly mounted. The support platform 300 is equipped with a rotating assembly 400 for controlling the rotation of food on the grill, and an air-blowing assembly 600 for blowing air into the placement cavity 110. Casters 310 are provided at the bottom of the support platform 300 for easy movement, facilitating its movement to different grilling positions. Mounting plates 320 are located on the left and right sides of the support platform 300 on the barbecue grill shell, which can be used to temporarily place food or serving dishes for grilling.

[0045] Specifically, the rotating assembly 400 includes a drive shaft 410, a first rotating shaft 420, a second rotating shaft 430, and a rotating column. A first sprocket 411 is fixedly mounted on the drive shaft 410 and is rotatably connected to the support platform 300. Both the first rotating shaft 420 and the second rotating shaft 430 are rotatably connected to the support platform 300. The rotating column is rotatably connected to the base 100, with one end extending into the placement cavity 110. A second sprocket 421 is mounted at one end of the first rotating shaft 420, and a first bevel gear 422 is mounted at the other end. A second bevel gear 431 is mounted at one end of the second rotating shaft 430, and a third sprocket 432 is mounted at the other end. A fourth sprocket 443 is mounted at the other end of the rotating column. The drive shaft 410 and the first rotating shaft 420 are connected by a first conveyor belt 412, which is an annular structure and is connected to both the first sprocket 411 and the second sprocket 421. The first rotating shaft 420 and the second rotating shaft 430 are perpendicularly connected and driven by the meshing of the first bevel gear 422 and the second bevel gear 431. The second rotating shaft 430 is connected to the rotating column by a second conveyor belt 433, which is a ring structure and is connected to the third sprocket 432 and the fourth sprocket 443. When the drive shaft 410 rotates, it drives the first rotating shaft 420 to rotate, which in turn drives the second rotating shaft 430 to rotate, and the second rotating shaft 430 drives the rotating column to rotate. In this embodiment, both the first transmission belt 412 and the second conveyor belt 433 are chains.

[0046] Reference Figure 4 and Figure 5 Multiple rotating columns are provided, and each rotating column is fixed with a transmission component 442. All rotating columns are interconnected via the transmission components 442; in this embodiment, the transmission component 442 is a gear. When the second conveyor belt 433 drives the fourth sprocket 443 to rotate, one of the rotating columns rotates synchronously, and the remaining rotating columns rotate synchronously due to the mutual meshing of the transmission components 442. One end of each rotating column has a limiting hole 441 within the placement cavity 110. Using the limiting hole 441, when food is skewered with a skewer 500, one end of the skewer 500 can abut against the limiting hole 441. When the rotating column rotates, it drives the skewer 500 to rotate simultaneously. At this time, the food rotates and flips over, accelerating the cooking time. The process does not require manual operation for flipping, avoiding localized burns to the fingers. It should be noted that, in order to facilitate the rotation of the skewer 500 by the rotating column, a square structure is preferred for the skewer 500 during use, and the corresponding limiting hole 441 is also square, which is conducive to the flipping of food during the process. When the skewer 500 uses other structures, the corresponding limiting hole 441 is changed accordingly, so that the skewer 500 can be flipped normally. In this embodiment, no specific limitation is made on the structure of the skewer 500 and the structure of the limiting hole 441.

[0047] Reference Figure 6 and Figure 7 The first rotating shaft 420 is located at the bottom of the base 100, and a cam 423 is fixedly connected to the first rotating shaft 420. The air blowing assembly 600 is movably connected to the cam 423. The air blowing assembly 600 includes an air pump 610 and a transmission rod 620. The air pump 610 includes a sleeve 611 and a plunger 613. The plunger 613 is movably inserted into the sleeve 611 and slides directly along the sleeve 611. It should be noted that in this embodiment, the structural principle of the air pump 610 is the same as that of a syringe, which is existing technology. One end of the sleeve 611 is located in the placement cavity 110, and this end is provided with multiple ports 612, which communicate with the plunger 613 inside the sleeve 611. The air pump 610 is arranged perpendicularly to the first rotating shaft 420. One end of the transmission rod 620 is rotatably connected to the plunger 613, and the other end is rotatably connected to the cam 423. When the first rotating shaft 420 rotates, the cam 423 drives the plunger 613 to move linearly along the inside of the sleeve 611 via the transmission pin. This allows air to enter the sleeve 611 through the port 612. As the plunger 613 slides back and forth, the air inside the sleeve 611 is injected into the placement cavity 110 through the port 612. At this time, the charcoal burns faster under the action of the airflow, and the food is cooked more easily. The airflow through the port 612 helps to evenly distribute the temperature inside the placement cavity 110, ensuring that all food is heated evenly.

[0048] It should be noted that in this embodiment, the air blowing component 600 does not require separate control. It can be driven synchronously when the first rotating shaft 420 on the rotating component 400 rotates. The structure has strong linkage and is easy to operate.

[0049] The implementation principle of this application embodiment is as follows: When the drive shaft 410 rotates, the first rotating shaft can synchronously drive the plunger 613 to move linearly along the inside of the sleeve 611 through the cam 423, so that air enters the inside of the sleeve 611 through the port 612. As the plunger 613 slides back and forth, the air inside the sleeve 611 is injected into the placement cavity 110 through the port 612. At this time, the charcoal burns faster under the action of the blowing air, and the food is easier to cook.

[0050] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
