Description

Technical Field

[0001] This invention relates to the field of food processing technology, and in particular to a chicken roasting oven. Background Technology

[0002] Chicken roasting ovens are widely used in the food processing field as everyday cooking tools. For example, Chinese invention patent number 201621197892X discloses a portable chicken roasting oven, which includes a charcoal box, a bracket fixed to both sides of the charcoal box, and a rotating shaft rotatably connected to the bracket. One end of the rotating shaft is equipped with a motor that provides power. The rotating shaft is equipped with two roasting forks for fixing the chicken. The roasting forks are arranged facing each other and slidably connected to the rotating shaft. The roasting forks are equipped with locking parts for locking to the rotating shaft.

[0003] The above-described chicken roaster is a common horizontal roaster structure. It uses a motor-driven shaft to rotate the roasting fork, on which the chicken is skewered. While roasting, oil drips down into the charcoal box, producing some smoke and benzopyrene, which is harmful to the health of those roasting the chicken. In addition, the motor-driven structure requires an external power source, which is inconvenient when there is no external power source. Furthermore, the horizontal structure occupies a large area. Therefore, improvements are needed. Summary of the Invention

[0004] The technical problem to be solved by this invention is to provide a chicken roasting oven that does not require an external power supply, produces no oil fumes, and is easy to disassemble and clean, in order to address the shortcomings of existing horizontal chicken roasting ovens that require an external power supply.

[0005] This application provides a chicken roasting oven, characterized in that it includes a vertically placed support cylinder and an upper bracket fixed inside the support cylinder. A rotating shaft is rotatably mounted on the upper bracket, and two roasting forks for fixing the chicken are provided on the rotating shaft. A charcoal trough assembly for placing charcoal is installed inside the support cylinder and on one side of the roasting forks. An air inlet is provided on the side wall of the support cylinder. A lower bracket is provided at the bottom of the support cylinder and below the upper bracket. The lower bracket is provided with an insertion hole for the lower end of the rotating shaft to be rotatably inserted into the insertion hole.

[0006] Preferably, the upper support has a rotating hole, and an inlet groove is provided on one side of the rotating hole. A lower rotating sleeve is rotatably sleeved on the rotating shaft. A lower limiting ring is connected to the top of the lower rotating sleeve. The rotating shaft is rotatably mounted at the rotating hole through the lower rotating sleeve. A first retaining spring is provided on the rotating shaft and located between the lower rotating sleeve and the roasting fork.

[0007] Preferably, the support cylinder is formed by splicing two semi-circular semi-circular cylinders. Several fixing holes are provided at the splice point of the two semi-circular cylinders along the height direction. After the two semi-circular cylinders are spliced, they are fixed to each other by several screws installed into the fixing holes. The air inlet is set on one of the semi-circular cylinders.

[0008] Preferably, a base is provided at the bottom of the support cylinder.

[0009] Preferably, the upper section of the rotating shaft has a non-circular cross-sectional shape, an upper rotating sleeve is rotatably inserted into the upper section of the rotating shaft, an upper limit ring is connected to the top of the upper rotating sleeve, the cross-sectional shape of the inner hole of the upper rotating sleeve is adapted to the cross-sectional shape of the upper section of the rotating shaft, a rotating disk is fixed on the upper rotating sleeve, a plurality of fan blades are arranged sequentially along the outer edge of the rotating disk in the circumferential direction, and a second retaining spring is arranged on the rotating shaft and between the upper rotating sleeve and the lower rotating sleeve.

[0010] Preferably, the upper end of the rotating shaft passes through the top opening of the support cylinder and is connected to the rotating disk, and the ends of several fan blades away from the rotating shaft extend to the top edge of the support cylinder.

[0011] Preferably, the top of the rotating disk is provided with a handle cover plate for inserting tools to lift the rotating disk, several fan blades and the upper rotating sleeve. The handle cover plate is U-shaped and has a through hole in the middle for the upper end of the rotating shaft to pass through.

[0012] Preferably, the charcoal trough assembly includes a charcoal trough body having a charcoal trough, and the side of the charcoal trough body facing the roasting fork is provided with a plurality of evenly distributed heat holes communicating with the charcoal trough.

[0013] Preferably, the side of the charcoal trough body away from the roasting fork is detachably installed in the support cylinder via a detachable component. The detachable component includes two hooks fixed to the charcoal trough body, and the top of the support cylinder is provided with two U-shaped grooves, with the two hooks correspondingly hooked into the two U-shaped grooves.

[0014] Preferably, the cross-section of the charcoal tank body is configured as a fan-shaped ring with a central angle of °-°, and its arc-shaped inner surface faces the roasting fork.

[0015] Preferably, the charcoal tank body has a U-shaped handle cover plate on its tank wall for inserting tools to lift the charcoal tank body, and the U-shaped handle cover plate has a clearance hole in the middle.

[0016] This chicken roaster utilizes a rotating disc and circumferential fan blades at the top of the shaft. The rising hot air from the charcoal fire drives the fan blades, which in turn rotates the shaft and the roasted chicken at a constant speed, completely replacing the traditional motor drive. This effectively solves the problem of unusable roasters in situations without power, such as outdoor camping, picnics, and mobile stalls, while also being energy-efficient, environmentally friendly, and eliminating electrical safety hazards. The side-mounted charcoal trough and vertical chicken roasting layout ensures the charcoal fire is located to the side of the roasting fork rather than directly beneath it. This allows dripping oil from the chicken to fall directly into the bottom of the support cylinder, avoiding contact with the charcoal fire. This completely eliminates the production of fumes and carcinogenic substances like benzopyrene from burning oil, while also preventing the chicken from being charred by open flames. Compared to traditional horizontal chicken roasters, this significantly reduces the horizontal footprint, resulting in a more compact structure. Attached Figure Description

[0025] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0026] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0027] The embodiments of this application will be described in detail below with reference to the accompanying drawings and specific examples and application scenarios.

[0028] Example 1: like Figures 1-8 As shown, a chicken roasting oven, in a specific embodiment of the present invention, includes a vertically placed support cylinder 1 and an upper bracket 2 fixed inside the support cylinder 1. A rotating shaft 3 is rotatably mounted on the upper bracket 2. Two roasting forks 31 for fixing the chicken are provided on the rotating shaft 3. A charcoal trough assembly for placing charcoal is installed inside the support cylinder 1 and on one side of the roasting forks 31. An air inlet is provided on the side wall of the support cylinder 1. A lower bracket 6 is provided at the bottom of the support cylinder 1 and below the upper bracket 2. The lower bracket 6 is provided with an insertion hole for the lower end of the rotating shaft 3 to be rotatably inserted into the insertion hole.

[0029] By adopting the above technical solution and using a side-mounted charcoal trough and a vertical chicken roasting layout, the charcoal fire is located on the side of the roasting fork rather than directly below it. During roasting, the dripping oil falls directly into the bottom of the support cylinder, avoiding contact with the charcoal fire. This completely avoids the production of fumes and carcinogenic substances such as benzopyrene from burning oil, while also eliminating the problem of localized charring of the chicken due to open flames. Compared to traditional horizontal chicken roasting ovens, this significantly reduces the horizontal footprint, resulting in a more compact structure. The air inlet provides ample oxygen to the charcoal fire, ensuring more complete combustion, stronger heat, and improved thermal efficiency. While providing sufficient oxygen, the roasted chicken can be easily removed from the air inlet, or a chicken waiting to be roasted can be inserted into the roasting fork. The dual-point coaxial support structure (upper and lower supports) solves the problems of wobbling and eccentricity associated with single-point supports, ensuring stable and unbiased rotation of the shaft. This improves the uniformity of chicken rotation and prevents safety hazards caused by shaft detachment.

[0030] In a specific embodiment of the present invention, the upper bracket 2 is provided with a rotating hole 100, and an inlet groove is provided on one side of the rotating hole 100. A lower rotating sleeve 101 is rotatably sleeved on the rotating shaft 3. A lower limiting ring is connected to the top of the lower rotating sleeve 101. The rotating shaft 3 is rotatably mounted at the rotating hole 100 through the lower rotating sleeve 101. A first retaining spring 102 is provided on the rotating shaft 3 and located between the lower rotating sleeve 101 and the roast fork 31.

[0031] By adopting the above technical solution, it is possible to achieve the following when installing the rotating shaft 3: Figure 6 As shown, first insert the lower end of the rotating shaft 3 into the insertion hole, and then rotate the rotating shaft 3 through the inlet groove into the rotating hole 100. At this time, move the lower rotating sleeve 101, which is rotatably sleeved on the rotating shaft 3, downward and insert it into the rotating hole 100. The lower limit ring limits it downward. The outer diameter of the lower rotating sleeve 101 is equal to the inner diameter of the rotating hole 100, and the groove width of the inlet groove is smaller than the outer diameter of the lower rotating sleeve 101, thereby realizing the rotational installation of the rotating shaft 3. When disassembling, lift the rotating shaft 3. After lifting, the first retaining spring 102 limits the lower rotating sleeve 101, and then the rotating shaft 3 can be taken out through the inlet groove. The installation and disassembly of the rotating shaft 3 is convenient and quick.

[0032] In a specific embodiment of the present invention, two roasting forks 31 are arranged opposite to each other and slidably connected to the rotating shaft 3, and a locking member 32 for locking the roasting forks 31 to the rotating shaft 3 is provided at the connection between the roasting forks 31 and the rotating shaft 3.

[0033] By adopting the above technical solution, the distance between the two roasting forks can be flexibly adjusted according to the size and weight of the roasted chicken, making it suitable for whole chickens of different sizes such as young chickens, yellow-feathered chickens, and free-range chickens; the locking part can firmly fix the position of the roasting forks to prevent the roasted chicken from slipping during the roasting process, while the operation of assembling and disassembling the roasted chicken is convenient.

[0034] In a specific embodiment of the present invention, the support cylinder 1 is formed by splicing two semi-annular semi-circular cylinders. Several fixing holes are respectively provided at the splicing point of the two semi-annular cylinders along the height direction. After the two semi-annular cylinders are spliced, they are installed into the fixing holes by several screws to achieve mutual fixation. The air inlet is provided on one of the semi-annular cylinders.

[0035] By adopting the above technical solution, the support cylinder can be completely disassembled and opened to expose the entire internal space, making it convenient for deep cleaning of oil stains, food residues and carbon deposits, solving the pain point of the difficulty in cleaning the inside of traditional integrated ovens; after disassembly, the volume is greatly reduced, making it easy to store and transport over long distances.

[0036] In a specific embodiment of the present invention, a base 5 is provided at the bottom of the support cylinder 1.

[0037] By adopting the above technical solutions, the overall center of gravity of the equipment is lowered, the stability of placement is enhanced, and tipping over due to collisions, wind, or shaft rotation during the baking process is prevented, especially improving the safety of use on uneven outdoor ground.

[0038] In a specific embodiment of the present invention, the upper section of the rotating shaft 3 has a non-circular cross-sectional shape, and an upper rotating sleeve 103 is rotatably inserted into the upper section of the rotating shaft 3. An upper limit ring is connected to the top of the upper rotating sleeve 103. The cross-sectional shape of the inner hole of the upper rotating sleeve 103 is adapted to the cross-sectional shape of the upper section of the rotating shaft 3. A rotating disk 7 is fixed on the upper rotating sleeve 103. A plurality of fan blades 8 are arranged sequentially along the outer edge of the rotating disk 7 in the circumferential direction. A second retaining spring 104 is arranged on the rotating shaft 3 and between the upper rotating sleeve 103 and the lower rotating sleeve 101.

[0039] By adopting the above technical solution, the non-circular cross section of the upper section of the shaft is precisely matched with the inner hole of the upper rotating sleeve, achieving circumferential hard limiting. When the hot airflow drives the fan blades, the power is 100% transmitted to the shaft, without slippage or free rotation. The upper limit ring and the second retaining spring provide double axial locking to prevent the upper rotating sleeve from loosening or shifting. The rotating disk and fan blades rely on the rising hot airflow from the charcoal fire to rotate, completely replacing the motor drive. No external power supply is required, which is energy-saving, environmentally friendly, and eliminates electrical safety hazards such as leakage and short circuit.

[0040] In a specific embodiment of the present invention, the upper end of the rotating shaft 3 passes through the top opening of the support cylinder 1 and is connected to the rotating disk 7, and the ends of several fan blades 8 away from the rotating shaft 3 extend to the top edge of the support cylinder 1 respectively.

[0041] By adopting the above technical solution, the rising hot airflow inside the support cylinder is maximized. Combined with the forced convection formed by the side wall air inlet, the driving force of the airflow on the fan blades is significantly improved, ensuring the stability of the shaft speed. The fan blades extending to the top edge can form a guiding effect, accelerating the internal hot air circulation and further improving the heat utilization rate and baking efficiency.

[0042] Example 2: The difference from Embodiment 1 is that, in addition to including the structural features of the aforementioned embodiments, in the specific embodiments of the present invention, such as... Figures 1-7 As shown, the charcoal trough assembly includes a charcoal trough body 42 with a charcoal trough 41, and the side of the charcoal trough body 42 facing the roasting fork 31 is provided with a plurality of evenly distributed heat holes 43 communicating with the charcoal trough 41.

[0043] By adopting the above technical solution, the heat generated by the charcoal fire is radiated directionally and evenly to the whole body of the roasted chicken through evenly distributed heat holes, avoiding excessively high or low local heat, ensuring that all parts of the roasted chicken are heated evenly, and the roasted chicken has a crispy skin and tender meat inside, with stable and controllable quality.

[0044] In a specific embodiment of the present invention, the side of the charcoal trough body 42 away from the roasting fork 31 is detachably installed in the support cylinder 1 by a detachable component. The detachable component includes two hooks 44 fixed to the charcoal trough body 42. The top of the support cylinder 1 is provided with two U-shaped grooves 45, and the two hooks 44 are correspondingly hung into the two U-shaped grooves 45.

[0045] By adopting the above technical solutions, the charcoal trough assembly can be quickly disassembled and assembled without tools, making it convenient to add charcoal and clean charcoal ash at any time. The operation is simple and efficient. The hanging structure is stable and will not cause the charcoal trough to fall off due to vibration or airflow.

[0046] In a specific embodiment of the present invention, the cross-section of the charcoal tank body 42 is configured as a fan-shaped ring with a central angle of 90°-180°, and its arc-shaped inner side faces the roasting fork 31.

[0047] By adopting the above technical solution, the cross-section of the charcoal trough body 42 is more fan-shaped than that of a cuboid, which increases the area of ​​the charcoal fire and the area of ​​the part facing the roasted chicken, thereby improving the heat utilization rate.

[0048] Example 3: The difference from Embodiment 2 is that, in addition to including the structural features of the aforementioned embodiments, in the specific embodiments of the present invention, such as... Figures 4-6 As shown, the upper support 2 and the lower support 6 are arranged vertically opposite each other. Each support has mounting holes on its left and right sides that mate with the fixing holes on the two semi-ring cylinders. This allows for simultaneous installation of the upper support 2 and the lower support 6 while the two semi-ring cylinders are being installed, resulting in a more rational and simpler structure. Using this structure, there is no need to install the upper and lower supports separately; the upper and lower supports can be fixed while the semi-ring cylinders are being assembled, improving assembly efficiency and structural stability.

[0049] Example 4: The difference from Embodiment 3 is that, in addition to including the structural features of the aforementioned embodiments, in this specific embodiment of the invention, to further facilitate the overall rotation of the roasting fork 31 and the rotating shaft 3, the lower end of the rotating shaft 3 is set in a conical shape, such as... Figure 6 As shown.

[0050] The lower end of the shaft is designed to be conical, which reduces the contact area between the shaft and the insertion hole, reduces rotational friction, makes the shaft rotate more smoothly, and further improves the uniformity of the roasted chicken rotation.

[0051] Example 5: The difference from Embodiment 4 is that, in addition to including the structural features of the foregoing embodiments, in the specific embodiments of the present invention, such as... Figure 8As shown, the top of the rotating disk 7 is provided with a handle cover plate 105 for inserting tools to lift the rotating disk 7, several fan blades 8 and the upper rotating sleeve 103. The handle cover plate 105 is U-shaped and has a through hole in the middle for the upper end of the rotating shaft 3 to pass through.

[0052] The U-shaped handle cover can be used with common tools (such as screwdrivers) to quickly lift the rotating disk, fan blades, and upper rotating sleeve assembly. Alternatively, it can be used with... Figure 8 The U-shaped handle shown allows for quick disassembly, facilitating daily cleaning, maintenance, and parts replacement; the perforation in the middle avoids obstructing the upper end of the shaft, ensuring normal rotation; the structural design is ingenious and reasonable.

[0053] Example 6: The difference from Embodiment 5 is that, in addition to including the structural features of the foregoing embodiments, in the specific embodiments of the present invention, such as... Figure 6 As shown, a U-shaped handle cover plate with the same structure as the top of the rotating disk 7 is also provided on the wall of the charcoal tank body 42, which can be used with ordinary tools or special U-shaped handles to quickly lift the entire charcoal tank body 42, further improving the convenience of disassembling and cleaning the charcoal tank.
