[0002] In the prior art, there are large-sized barbecued foods, such as roasted whole adult pigs, whole sheep, or roasted dairy cows. Such barbecued foods are characterized by large foods, and the length of the hanging food is about 1.5 meters. Such foods are usually baked in a naan pit furnace, where charcoal, firewood, etc. are ignited in the naan pit furnace, and the whole pig is hung into the naan pit furnace after a heating process, and then the furnace is sealed and baked.
[0003] Baking in a naan pit oven is subject to environmental protection requirements. Therefore, it is not possible to bake large pigs in urban areas and other places that require smoke-free environment protection. It is also not possible to build a naan pit oven due to site constraints. Even if it is baked in a naan pit oven, the smoke generated needs to be equipped with a smoke exhaust device to reduce the impact of smoke on the baking personnel, which increases costs. At the same time, because the heat source of baking in a naan pit oven only comes from the bottom of the naan pit oven, the roasted pig is not heated evenly, resulting in different tastes.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0044] Embodiment 1
[0045] like Figure 1-10 As shown, an electric oven mainly used for roasting large pigs comprises an oven body 1 and an oven door 11 matched with the oven body 1, wherein a heating lamp 2 is arranged inside the oven body 1, and a partition 17 is arranged inside the oven body 1 and above the heating lamp 2, the partition 17 divides the internal space of the oven body 1 into an upper part and a lower part, and an air outlet 18 and an air inlet 171 are respectively opened at the center and both sides of the partition 17 to connect the upper and lower spaces, and an induced draft fan 7 is arranged on the partition 17 and above the air outlet 18; a hook 3 and a driving device for driving the hook 3 to rotate are rotatably arranged inside the oven body 1 and below the air outlet 18.
[0046] The furnace body 1 is also provided with an exhaust pipe connected to the internal space of the furnace body 1 , and the exhaust pipe 1 is provided with a valve plate 85 for controlling the opening and closing of the exhaust pipe 1 .
[0047] Specifically in this embodiment, Figure 1-2 As shown, the furnace body 1 is a vertically extending rectangular structure, a furnace mouth is reserved at the front side of the furnace body, the furnace door 11 is hinged to the furnace body 1 through a hinge seat, and a sealing gasket 16 is provided at the inner edge of the furnace door, specifically a rubber gasket, which is used to increase the sealing and thermal insulation performance of the furnace door 11.
[0048] As a specific implementation, the heating lamp tubes 2 are multiple and are evenly arranged on the inner wall of the left side, right side and rear side of the furnace body 1. Figure 7 and Fig.10As shown, two vertically parallel brackets 21 are provided on the inner walls of the left side, right side and rear side of the furnace body 1, and the two ends of the heating lamp tube 2 are respectively fixed to the corresponding brackets 21 on both sides through mounting bases. The heating lamp tube 2 is arranged at equal intervals along the bracket 21 to ensure uniform heating.
[0049] The inner wall of the furnace body 1 is also provided with a wiring tube 22 for wiring the heating lamp 2, which not only increases the beauty and neatness of the interior of the furnace body 1, but also provides protection for the circuit. The wiring tube 22 is provided on both sides of the corresponding heating lamp 2 of the inner wall of the furnace body 1 and is parallel to the bracket 21.
[0050] As a specific implementation method, Figure 5-6 As shown, a crossbeam 19 is provided in the furnace body 1 and below the partition 17, and the hook 3 is rotatably provided on the crossbeam 19 through an axle seat. The hook 3 is used to hook the roasted pig, and the roasted pig hung on the hook 3 rotates under the driving action of the driving device, and is heated and cooked under the baking action of the heating lamp 2.
[0051] As a specific implementation method, Figure 3 , Figure 5-6 As shown, the driving device includes a driving motor 51 fixed on the furnace body 1 and a reducer 52 matched with the driving motor 51 , and a transmission shaft 53 of the reducer 52 is matched and connected with the hook 3 .
[0052] Of course, this embodiment also includes a power distribution cabinet 14, in which electrical components for connecting and controlling the device circuit are arranged. The power distribution cabinet 14 is riveted to one side of the furnace body 1, and an electric cabinet door 15 is hinged at the furnace mouth of the power distribution cabinet 14.
[0053] Preferably, the driving motor 51 and the reducer 52 are arranged in the distribution cabinet 14, the transmission shaft 53 corresponding to the reducer 52 passes through the furnace body 1 and extends to the inside of the furnace body 1, and the transmission shaft 53 is fixed on the cross beam 19 through an axle seat; a rotating shaft 32 is arranged on the top of the hook 3, and the rotating shaft 32 is fixed on the cross beam 19 through an axle seat, and the transmission shaft 53 and the rotating shaft 32 are matched through a bevel gear 6.
[0054] Furthermore, the hook 3 also includes a hanging plate 31 arranged around the hook 3, the hanging plate 31 is arranged in a circular ring structure, and serrated grooves are evenly arranged around the top of the hanging plate 31. Specifically, the hanging plate 31 is fixedly connected to the rotating shaft 32 through a connecting rib plate. In order to ensure the stability of a large roasted pig during rotation, a pig may need to be suspended by multiple hanging ropes. The hanging plate 31 can be used to hook multiple hanging ropes, which is suitable for roasted pigs with larger bodies.
[0055] Furthermore, if Figure 7 and Fig.10As shown, a mirror reflection tile 23 is arranged between the furnace body 1 and the heating lamp tube 2. The mirror reflection tile 23 is arranged in a corrugated structure to increase the heating area, reduce the large amount of heat transfer from the heating lamp tube 2 directly to the inner wall of the furnace body 1, increase the performance of the baking space inside the furnace body 1, and reduce energy consumption. The mirror reflection tile 23 is made of steel material and polished into a reflective surface, which can reflect the heat radiation of the heating lamp tube and improve the heat utilization rate.
[0056] As a specific implementation method, Figure 1 and Figure 8-9 As shown, the exhaust pipe 8 is arranged at the top of the furnace body 1, and the exhaust pipe 8 includes a tube 81, one end of which is connected to the outside atmosphere, and the other end extends into the space inside the furnace body 1 and is located above the partition 17. A connecting seat 82 is arranged on the outside of the tube 81, and a permanent magnet motor 83 is arranged on the connecting seat 82. The driving shaft 84 of the permanent magnet motor 83 passes through the tube 81 and extends to the inside of the tube 81. A valve plate 85 fixedly connected to the driving shaft 84 is arranged in the tube 81. The valve plate 85 is arranged in a circular structure and has the same inner diameter as the tube 81. A first limit plate 86 is arranged on the connecting seat 82 and on both sides of the driving shaft 84 and is in the same horizontal plane as the driving shaft 84. Two second limit plates 86 are arranged on the driving shaft 84. Two limit plates 87, a 90° angle is formed between the two second limit plates 87, and the first limit plate 86 interferes with the second limit plate 87 rotating with the drive shaft 84. When one of the second limit plates 87 is interfered by the first limit plate 86, the valve plate 85 completely blocks the tube 81, and the exhaust pipe 8 is in a state where exhaust cannot be exhausted; when the other second limit plate 87 is interfered by the first limit plate 86, the valve plate 85 rotates 90° relative to the blocking state, and the tube 81 is in an open state, which can be exhausted. The exhaust pipe 8 is mainly used when baking pork with a relatively high tax content. Since baking with a high water content causes a large amount of water vapor evaporation, the internal air pressure of the furnace body 1 is relatively high, which affects the quality of the barbecue and increases the risk of opening the furnace. Therefore, the exhaust pipe 8 is used to exhaust and release pressure to ensure the quality of the barbecue and safety of use.
[0057] Furthermore, if Figure 1-2 As shown, the oven door 11 is provided with a viewing window 111, through which the roasting state of the roasted pig inside the oven body can be seen, whether the roasted pig is cooked, etc. can be judged. Specifically, the oven door 11 is provided with a viewing window (not shown in the figure), and a transparent plate is embedded in the viewing window, and the viewing window and the transparent plate together form the viewing window 111. Preferably, the transparent plate is made of tempered glass, which has the advantages of being wear-resistant and high-temperature resistant.
[0058] Furthermore, if Figure 7 As shown, a temperature detector 9 is disposed inside the furnace body 1, and a temperature display (not shown in the figure) electrically connected to the temperature detector 9 is disposed outside the furnace body 1 for real-time monitoring of the temperature condition inside the oven.
[0059] In this embodiment, a controller 4 for controlling circuit electrical components is also included, such as an industrial computer, a PLC controller, etc. The controller is embedded on the outside of the power distribution cabinet 14 .
[0060] It should be noted that the above-mentioned controller is connected to the heating lamp tube, drive motor, permanent magnet motor, induced draft fan, temperature detector, and temperature display through wires, and the specific connection method belongs to the existing conventional technology and will not be elaborated here.
[0061] Preferably, the length of the front, back, left and right space inside the furnace body 1 for accommodating the roasted pig is set at about 110 cm, and the upper and lower height is set at about 170 cm, ensuring that there is enough space to accommodate a larger pig.
[0062] Note: Larger pigs here refer to adult pigs. When they reach adulthood, their weight is about 129 kg (sows) to 140 kg (boars) and their length is between 135 cm and 139 cm. It should be noted that although pigs are sexually mature at around 6 months old, adult pigs usually refer to pigs aged 12 months or older.
[0063] The traditional naan pit floor oven occupies an area of more than 3 square meters. In this embodiment, the outer front and rear and left and right dimensions of the furnace body 1 are set to be about 120 cm, and the total area is about 1.5 square meters. Compared with the traditional naan pit floor oven, the floor area is greatly reduced, and it can be used indoors and outdoors in urban and suburban areas without being restricted by the site.
[0064] Furthermore, a running wheel 13 is provided at the bottom of the oven body 1. Preferably, the running wheel 13 is a universal wheel to facilitate the movement and displacement adjustment of the oven.
[0065] Working principle: When in use, the roasted pig is hung on the hook 3 or the hanging plate 31, and the controller 4 controls the driving motor 51 to drive the rotating shaft 32 to rotate, so that the roasted pig rotates at a constant speed inside the furnace body 1, and at the same time controls the heating lamp 2 to emit light and heat, so as to bake the roasted pig that rotates at a constant speed.
[0066] While the roasted pig rotates in the furnace body 1, the induced draft fan 7 introduces the air in the roasting space of the roasted pig in the furnace body 1 to the top of the partition 17, and at the same time returns it to the roasting space again through the air outlet 18, so that a hot air circulation is formed in the furnace body 1, so that the hot air contacts the roasted pig evenly, thereby increasing the roasting efficiency and the roasting quality.
[0067] An oil receiving pan is placed at the bottom of the furnace body 1 to receive the dripping grease from baking.
[0068] The baking status of the barbecue can be viewed in real time through the window 111 on the oven door 11 to determine whether it is cooked. If it is cooked, the permanent magnet motor 83 can be controlled by the controller 4 to drive the valve plate 85 to open, and then the oven door 11 can be opened to exhaust the air and heat to take out the roasted pork.
[0069] Embodiment 2
[0070] An oil drain pipe (not shown in the figure) communicating with the furnace body is arranged at the bottom of the furnace body 1, and a valve (not shown in the figure) is arranged at the oil outlet of the oil drain pipe.
[0071] The rest is the same as in the first embodiment.
[0072] The oil and water produced by baking can be directly discharged through the oil-beating pipe, which is convenient for the discharge of oil and water.
[0073] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
