Description

Technical Field

[0001] The present invention relates to the field of ovens, and specifically refers to an oven that facilitates uniform heating of skewered foods. Background Art

[0002] For people who are relatively busy in daily life, delicious food is a great comfort to the soul. Among various dishes, grilled meat is the most popular among young people. In the prior art, an oven usually has a fixed or detachable baking tray inside the oven cavity, and the food is baked on the baking tray. For example, an oven disclosed in Publication (Announcement) No. CN104665616B. However, when grilling meat with this kind of oven, due to the heating position of the oven, it is very easy to burn the food near the upper heating tube, or the situation where the surface is scorched while the inside is not cooked.

[0003] To solve the above problems, Publication (Announcement) No. CN216020586U in the prior art discloses an oven for food processing, and Publication (Announcement) No. CN217524714U discloses an oven cage with a tumbling and stirring structure; in the above two prior arts, a rotatable barrel-shaped cage is provided inside the oven, and the ingredients placed inside are tumbled by the rotation of the cage to make the ingredients evenly heated.

[0004] However, its defects are as follows:

[0005] 1. Although the problem of uniform heating is solved, it can only process loose meat chunks. In actual grilling, people usually habitually skewer the meat for baking, so as to facilitate direct taking and eating. The above prior art cannot bake meat skewers, and the meat skewers cannot be put into the cage for processing after being strung.

[0006] 2. Usually when grilling meat, cooking oil is brushed or some condiment powder is sprinkled during the baking process. If a cage is used, it is not convenient to brush oil or sprinkle condiment powder on the surface of the meat skewers.

[0007] 3. When using a cage to grill meat, grease is easily adhered to the inner wall of the cage. After baking, especially after multiple uses, the grease accumulates on the cage and is prone to adhering to impurities such as barbecue materials, and it is very difficult to clean after use.

[0008] In view of the above, it is necessary to propose an oven that facilitates uniform heating of skewered foods to solve the above problems. Summary of the Invention

[0009] The purpose of the present invention is to solve the above technical problems and provide an oven that facilitates uniform heating of skewered foods.

[0010] To achieve the above object, the present invention adopts the following technical solution: An oven facilitating uniform heating of string-like foods, comprising a baking space, with oven side walls provided at both ends of the baking space, and a uniform baking device provided in the baking space. The uniform baking device includes a turntable and a grill structure formed by a frame surrounded by cross beams. The two end turntables are fixedly connected by a plurality of cross beams. The grill structure is controlled by a driving mechanism to rotate within the baking space;

[0011] A circulating baking rack is provided inside the grill structure. The circulating baking rack is used for arranging and fixing barbecue skewers. The barbecue skewers are sequentially installed on the circulating baking rack, so that when the circulating baking rack operates, it circulates inside the grill structure in a caterpillar shape.

[0012] Further, central shafts are provided at the centers of the mutually remote sides of the two side turntables. The grill structure is rotatably connected to the oven side walls through the central shafts at both ends;

[0013] A driving mechanism is provided on at least one side oven side wall. The driving mechanism includes a driving motor, a transmission belt, and belt pulleys. Belt pulleys are provided on both the central shaft and the output shaft of the driving motor, and a transmission belt is sleeved on the two belt pulleys.

[0014] Further, the circulating baking rack includes two transmission chains arranged in parallel inside the grill structure. Each of the two transmission chains is supported by four inner guide wheels to form a rectangular shape. The guide wheels are all rotatably connected to the turntable. Counter bores are correspondingly provided on the mutually close sides of the two transmission chains. A number of counter bores are evenly arranged on the transmission chains. The correspondingly positioned counter bores of the two transmission chains are used to fix both ends of the barbecue skewers.

[0015] Further, at least one pair of guide wheels corresponding to each other on the inner sides of the two transmission chains are driving wheels. The two driving wheels are connected by a driving shaft. The driving shaft is rotatably connected to the turntable. The driving shaft synchronously drives the two driving wheels to make the two transmission chains operate synchronously; the circulating baking rack follows the rotation of the uniform baking device and operates passively. The rotation of the circulating baking rack is controlled by a passive structure.

[0016] Further, the passive structure includes a face gear ring and an intermediate shaft. A face gear ring is fixedly provided on one of the oven side walls. An intermediate shaft is rotatably connected to the turntable adjacent to this oven side wall. A gear one is provided at one end of the intermediate shaft. The gear one is meshed with the face gear ring. A driving sprocket is provided at the other end of the intermediate shaft. The driving sprocket is connected to the driving shaft through a connecting mechanism.

[0017] Further, the connecting mechanism includes a driven sprocket provided at one end of the driving shaft. A chain is sleeved on the driving sprocket and the driven sprocket.

[0018] Further, the connecting mechanism includes a middle rotating shaft, on which a driven sprocket and a second gear are provided. A chain is sleeved on the driven sprocket and the driving sprocket. The connecting structure further includes a moving gear and a third gear. A moving gear is arranged between the second gear and the third gear. The moving gear can be displaced along an arc-shaped notch. The center of the arc-shaped notch is concentric with the middle rotating shaft. When the moving gear is located at one end of the arc-shaped notch, it is meshed and connected with the second gear and the third gear respectively. After the moving gear is displaced, the moving gear is disengaged from the third gear. A spring for pushing the moving gear close to the third gear is further provided in the arc-shaped notch.

[0019] Further, one end of the barbecue skewer is provided with a fourth gear, and a rack is arranged on one side of the cross beam close to the transmission chain. The fourth gear is meshed and connected with the rack.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. The present invention adopts a frame structure formed by a cross beam and two end turntables, thus eliminating the cumbersome cleaning operation in the prior art and improving the user experience.

[0022] 2. When the frame-shaped grill structure rotates in the baking space, the baking uniformity of the meat skewers placed thereon can be improved.

[0023] 3. When the grill structure rotates, the driven structure is used to control the circulating baking rack to operate in a caterpillar track shape in the uniform baking device. Therefore, no matter where the barbecue skewer is installed on the circulating baking rack, each barbecue skewer can receive uniform baking, and the maturity of each skewer of meat is unified.

[0024] 4. The barbecue skewer can not only operate in a caterpillar track form, but also control the barbecue skewer to rotate automatically when the rack is meshed with the fourth gear, so that all sides of the meat on the barbecue skewer can be evenly heated. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0033] Embodiment 1:

[0034] An oven facilitating uniform heating of skewer-like foods includes a baking space, which is usually a rectangular cavity or a cylindrical cavity. Oven side walls 1 are provided at both ends of the baking space. A uniform baking device is arranged in the baking space. The uniform baking device includes a grill structure formed by a turntable 2 and a cross beam 3 enclosing a frame shape. Compared with the prior art using a drum-shaped rotating cage, the surrounding net-like structure around it is cancelled in this device, so that the heat of the oven can directly bake on the meat skewers, with better heat transfer effect, and the non-easy-to-clean net is removed, thus eliminating the cumbersome cleaning operation. Since the grill structure of this device is a frame structure, it is simple in structure and convenient to clean. As Figure 1 shown, the two turntables 2 at both ends are fixedly connected by a plurality of cross beams 3, and the grill structure is controlled by a driving mechanism to rotate in the baking space; as Figure 2 shown, central axes 5 are provided at the centers of the mutually remote sides of the two turntables 2 on both sides, and the grill structure is rotationally connected to the oven side walls 1 through the central axes 5 at both ends. It can be understood that when the grill structure rotates, it is rotationally connected to the oven side walls 1 through the central axes 5 at both ends. The positions of the heating wires arranged on the inner wall of the baking space are fixed. By rotating the grill structure, the meat skewers can rotate around the connection line of the two central axes 5 of the grill structure, facilitating uniform heating of the meat skewers; [[ID=2,3]]

[0035] The rotation of the grill structure is driven by a driving mechanism, as Figure 2As shown in the figure, a driving mechanism is provided on at least one side wall 1 of the oven. The driving mechanism includes a driving motor 6, a transmission belt 7, and pulleys 8. Pulleys 8 are provided on both the central shaft 5 and the output shaft of the driving motor 6. A transmission belt 7 is sleeved on the two pulleys 8. The driving motor 6 drives the turntable 2 to rotate through the transmission belt 7, so as to make the grill structure rotate.

[0036] Embodiment 2:

[0037] As Figure 3 shown in the figure, a circulating baking rack is provided inside the grill structure. The circulating baking rack is used to arrange and fix the barbecue skewers 4. The barbecue skewers 4 are sequentially installed on the circulating baking rack, so that when the circulating baking rack operates, it circulates inside the grill structure in a caterpillar shape; this embodiment further improves Embodiment 1. Since only the grill structure rotates in Embodiment 1, and the meat skewers for barbecue do not rotate, the meat skewers located at both ends of the grill structure may be unevenly heated. Therefore, in this embodiment, the sequentially arranged barbecue skewers 4 can operate like a caterpillar, so that the barbecue skewers 4 at each position can be evenly heated.

[0038] As Figure 3 shown in the figure, the circulating baking rack includes two transmission chains 9 arranged in parallel inside the grill structure. Each of the two transmission chains 9 is supported by four inner guide wheels 10 to form a rectangular shape, so that the transmission chain 9 can circulate when it operates. The transmission chain 9 can be made of a heat-resistant chain 19. The guide wheels 10 are all rotatably connected to the turntable 2. As Figure 2 shown in the figure, a mounting plate is vertically provided on the side wall of the turntable 2, and the guide wheels 10 are rotatably connected to the mounting plate. Sinking holes 11 are correspondingly provided on both sides of the two transmission chains 9 close to each other. A number of sinking holes 11 are evenly arranged on the transmission chain 9. The corresponding sinking holes 11 of the two transmission chains 9 are used to fix both ends of the barbecue skewer 4. During actual use, open the oven door, first insert one end of the barbecue skewer 4 into a sinking hole 11. Since the barbecue skewer 4 has a certain toughness, when installing the other end of the barbecue skewer 4, just slightly bend the barbecue skewer 4, and its end can be inserted into the corresponding other sinking hole 11. In this way, the barbecue skewers 4 can be sequentially arranged and installed in the corresponding sinking holes 11.

[0039] The circulating baking rack in this embodiment does not need to be driven by a separate driving motor 6. Specifically, as Figure 1 、 3As shown in the figure, at least one of the guide wheels 10 corresponding to each other in position on the inner sides of the two transmission chains 9 is a driving wheel 12. The two driving wheels 12 are connected by a driving shaft 13. During actual use, as long as the driving shaft 13 is controlled to rotate, the transmission chains 9 can be operated. The driving shaft 13 is rotationally connected to the turntable 2. The driving shaft 13 synchronously drives the two driving wheels 12 to make the two transmission chains 9 operate synchronously. The circulating baking rack can follow the rotation of the uniform baking device and perform driven operation. The circulating baking rack is controlled to rotate by a driven structure. As Figure 3 shown, the driven structure includes a face gear ring 14 and an intermediate shaft 15. The face gear ring 14 is fixedly arranged on one side of the oven side wall 1. The intermediate shaft 15 is rotationally connected to the turntable 2 adjacent to the oven side wall 1. A first gear 16 is arranged at one end of the intermediate shaft 15. The first gear 16 is meshed and connected with the face gear ring 14. A driving sprocket 17 is arranged at the other end of the intermediate shaft 15. The driving sprocket 17 is connected to the driving shaft 13 through a connecting mechanism.

[0040] As Figure 4 shown, the connecting mechanism includes a driven sprocket 18 arranged at one end of the driving shaft 13. A chain 19 is sleeved on the driving sprocket 17 and the driven sprocket 18. During actual use, since the turntable 2 is driven to rotate by the central shaft 5, the turntable 2 rotates relative to the face gear ring 14. By using this relative rotational movement, the face gear ring 14 drives the intermediate shaft 15 to rotate through the first gear 16. Then the intermediate shaft 15 makes the driving shaft 13 rotate through the sprocket-chain 19 structure, so as to realize the synchronous operation of the two transmission chains 9, and further drive the barbecue skewers 4 installed on the transmission chains 9 to move in a belt-like cycle.

[0041] Embodiment 3:

[0042] Since the meshing transmissions in Embodiment 2 are all gears or the chain 19, the operation time of the transmission chain 9 is associated with the operation of the turntable 2. Thus, when installing and taking the barbecue skewers 4, if the transmission chain 9 is pulled, the turntable 2 will also be driven to rotate, which causes inconvenience when taking or installing the barbecue skewers 4. This embodiment improves this problem. Specifically, as Figure 5 、 Figure 6 shown, the connecting mechanism includes a middle rotating shaft 23. A driven sprocket 18 and a second gear 21 are arranged on the middle rotating shaft 23. A chain 19 is sleeved on the driven sprocket 18 and the driving sprocket 17. The connecting structure further includes a moving gear 20 and a third gear 22. The moving gear 20 is arranged between the second gear 21 and the third gear 22. In this embodiment, the method of directly connecting the driving shaft 13 by the sprocket-chain 19 is not adopted, but the moving gear 20 is used for transmission. The moving gear 20 can shift along an arc-shaped notch 24. The center of the arc-shaped notch 24 is concentric with the middle rotating shaft 23. A spring 25 for pushing the moving gear 20 close to the third gear 22 is further arranged in the arc-shaped notch 24. As Figure 5As shown, when the moving gear 20 is located at one end of the arc notch 24, it is meshed and connected to the second gear 21 and the third gear 22 respectively. Under normal conditions, the moving gear 20 is pushed by the spring 25 to be close to the third gear 22 so as to facilitate meshing connection therewith. When meshed, it can drive the transmission chain 9 to operate. When it is necessary to pick up or place the barbecue skewer 4, the user can pull the drive chain. As Figure 6 shown, the drive chain is reversed to drive the third gear 22 to rotate in the direction of arrow C in the figure through the guide wheel 10. When the third gear 22 rotates in this direction, it can apply a torque in the direction of arrow D to the moving gear 20 meshed therewith, thereby pushing the moving gear 20 to compress the spring 25, so that the moving gear 20 is disengaged from the third gear 22. In this way, the user can pull the transmission chain 9 to rotate, which is convenient for picking up or placing the barbecue skewer 4 and will not drive the turntable 2 to rotate reversely.

[0043] Embodiment 4:

[0044] The implementation of the above embodiment can enable the barbecue skewer 4 to rotate around the center axis 5 connection line and also perform a transmission movement in the direction of the transmission chain 9. However, the barbecue skewer 4 itself does not rotate. This embodiment improves this problem. Specifically, as Figures 1 - 3 shown, a fourth gear 26 is provided at one end of the barbecue skewer 4, and a rack 27 is provided on the cross beam 3 close to the transmission chain 9. The fourth gear 26 is meshed and connected to the rack 27; when the transmission chain 9 drives the barbecue skewer 4 to move, the fourth gear 26 also remains meshed with the rack 27. Thus, when the barbecue skewer 4 moves, the rotation of the barbecue skewer can be driven through the rack 27. In this way, the meat skewer can rotate, rotate around the center axis 5 connection line and also move in a track-type cycle, so that the meat skewer is uniformly heated in an optimized manner.

[0045] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
