Description

Technical Field

[0001] This utility model relates to the technical field of solar oven equipment, specifically a portable concentrating solar oven. Background Technology

[0002] A solar collector is a device that converts solar radiation into heat energy. Because solar energy is relatively dispersed, it must be concentrated, making collectors a crucial component of various solar energy utilization devices. Due to different applications, collectors and their matching systems are categorized into many types with different names, such as solar cookers for cooking, solar water heaters for producing hot water, solar dryers for drying items, solar furnaces for smelting metals, as well as solar houses, solar thermal power plants, solar desalination plants, and so on. For solar collectors, higher efficiency collectors consist of collection and absorption devices. Sunlight consists of visible and invisible light of different wavelengths, and different substances and colors have different absorption and reflection capabilities for different wavelengths of light. Black absorbs sunlight most effectively, therefore cotton clothing is generally made of dark or black fabric. White reflects sunlight most effectively, therefore summer shirts are mostly light-colored or white. Therefore, black can be used to concentrate heat. By focusing parallel sunlight onto a point, a line, or a small area through a focusing lens, the purpose of heat collection can also be achieved; a solar-powered barbecue grill is a device that uses a reflector to absorb and capture sunlight to collect heat, and then grills food without smoke or pollution.

[0003] Currently, existing solar ovens require the frame to be assembled during use, which is cumbersome and inconvenient. After use, they also need to be disassembled and stored separately before they can be carried. They cannot be quickly and conveniently unfolded for use or stored and carried, which has certain shortcomings. To address this, we propose a portable concentrating solar oven. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a portable concentrating solar oven, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a portable concentrating solar oven, comprising an arc-shaped reflector, a heating tube, and a barbecue box, wherein the heating tube is disposed on the top of the arc-shaped reflector, the barbecue box is inserted into the interior of the heating tube, and a support adjustment mechanism is provided on both sides of the bottom of the arc-shaped reflector.

[0006] Furthermore, the support adjustment mechanism includes an adapter ear, an arc-shaped rotating rod, and a stabilizing tie rod. The adapter ear is fixedly installed on both sides of the bottom of the arc-shaped reflector. The arc-shaped rotating rod is rotatably connected to the adapter ear. Two threaded holes are opened inside both sides of the arc-shaped rotating rod. Connecting bolts are threaded into both ends of the stabilizing tie rod. The stabilizing tie rod is located on both sides of the arc-shaped rotating rod. The connecting bolts are threadedly connected to the threaded holes.

[0007] Furthermore, both sides of the inner side of the arc-shaped reflector are provided with support and fixing mechanisms for placing the heating tube.

[0008] Furthermore, the supporting and fixing mechanism includes two brackets, a limiting bracket, a threaded rod, and an arc-shaped pressure plate. The brackets are fixedly installed on both sides of the inner side of the arc-shaped reflector. An arc-shaped placement groove is opened inside the top of the bracket, and the heating tube cooperates with the arc-shaped placement groove. The limiting bracket is fixedly installed on the top of the bracket. The threaded rod is threadedly installed inside the top of the limiting bracket. The arc-shaped pressure plate is rotatably installed on one end of the threaded rod and cooperates with the heating tube. A throttle handle is fixedly installed on the other end of the threaded rod.

[0009] Furthermore, several J-shaped buckles are fixedly installed at the bottom of the arc-shaped reflector. The stabilizing rod cooperates with the J-shaped buckles. A strong magnet is provided at the bottom inside the J-shaped buckle, and the strong magnet cooperates with the stabilizing rod.

[0010] Furthermore, guide rods are fixedly installed on both sides of the top of the arc-shaped pressure plate, and the guide rods are slidably connected to the limiting frame.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figures 1 to 7 This utility model provides a technical solution: a portable concentrating solar grill, including an arc-shaped reflector 1, a heating tube 2, and a grill box 3. The heating tube 2 is located on the top of the arc-shaped reflector 1, and the grill box 3 is inserted into the interior of the heating tube 2. Support and adjustment mechanisms are provided on both sides of the bottom of the arc-shaped reflector 1. The heating tube 2 is made of glass and has a black heat-absorbing layer inside to facilitate heat absorption by concentrating solar energy. The support and adjustment mechanisms can be unfolded to support the arc-shaped reflector 1 and adjust its angle. After the arc-shaped reflector 1 is used, it can also be rotated to the top of the arc-shaped reflector 1 to serve as a lifting handle, thereby improving its portability.

[0021] The support and adjustment mechanism includes an adapter ear 4, an arc-shaped rotating rod 5, and a stabilizing tie rod 7. The adapter ear 4 is fixedly installed on both sides of the bottom of the arc-shaped reflector 1. The arc-shaped rotating rod 5 is rotatably connected to the adapter ear 4. Two threaded holes 6 are opened inside both sides of the arc-shaped rotating rod 5. Connecting bolts 8 are threaded into both ends of the stabilizing tie rod 7. The stabilizing tie rod 7 is set on both sides of the arc-shaped rotating rod 5, and the connecting bolts 8 are threadedly connected to the threaded holes 6. After rotating the arc-shaped rotating rod 5 to below the arc-shaped reflector 1, one end of the stabilizing tie rod 7 is first connected to the threaded hole 6 on one side of the arc-shaped rotating rod 5 through the connecting bolt 8 to install the stabilizing tie rod 7 on one side of the arc-shaped rotating rod 5. Then, the other end of the stabilizing tie rod 7 is connected to the other side through the other connecting bolt 8. The threaded hole 6 on one side of the arc-shaped rotating rod 5 completes the installation and fixation of the stabilizing pull rod 7. After the two stabilizing pull rods 7 are installed on both sides of the two arc-shaped rotating rods 5, the characteristic of the arc-shaped rotating rods 5 and the adapter ear 4 can be rotated to adjust the light-facing angle of the arc-shaped reflector 1 as needed, and it is supported by the arc-shaped rotating rods 5. It is convenient and quick to unfold and adjust the angle. After use, the stabilizing pull rods 7 and connecting bolts 8 are removed from both sides of the arc-shaped rotating rods 5. Then, the arc-shaped rotating rods 5 are rotated around the adapter ear 4 as the axis to the top of the arc-shaped reflector 1. The two arc-shaped rotating rods 5 can then form a lifting handle. Then, the arc-shaped reflector 1 can be lifted and carried by the arc-shaped rotating rods 5, which is more convenient and quick to carry.

[0022] Both sides of the inner side of the arc-shaped reflector 1 are provided with support and fixing mechanisms for placing the heating tube 2. The setting of the support and fixing mechanism makes it easy to support and fix the heating tube 2 to ensure its stability during use. After use, it is easy to release the restriction on the heating tube 2 and disassemble the heating tube 2 for cleaning.

[0023] The supporting and fixing mechanism includes two brackets 9, a limiting bracket 11, a threaded rod 12, and an arc-shaped pressure plate 13. The brackets 9 are fixedly installed on both sides of the inner side of the arc-shaped reflector 1. An arc-shaped placement groove 10 is opened inside the top of the bracket 9, and the heating tube 2 cooperates with the arc-shaped placement groove 10. The limiting bracket 11 is fixedly installed on the top of the bracket 9. The threaded rod 12 is threadedly installed inside the top of the limiting bracket 11. The arc-shaped pressure plate 13 is rotatably installed on one end of the threaded rod 12 and cooperates with the heating tube 2. A handle 14 is fixedly installed on the other end of the threaded rod 12. When fixing the heating tube 2, it is only necessary to place the heating tube 2... Place the heating tube 2 inside the arc-shaped placement groove 10 at the top of the two brackets 9. Then, turn the handle 14 to make the threaded rod 12 move down through the thread, which will drive the arc-shaped pressure plate 13 to press down. The arc-shaped pressure plate 13 can then press and fix the heating tube 2 from the top into the arc-shaped placement groove 10, thus completing the fixation of the heating tube 2 and ensuring the stability of the heating tube 2 during use. After the heating tube 2 is used, turn the handle 14 in reverse to make the threaded rod 12 move up through the thread, which will drive the arc-shaped pressure plate 13 to move up and release the restriction on the heating tube 2. Then the heating tube 2 can be removed from the arc-shaped placement groove 10 for cleaning.

[0024] Several J-shaped placement buckles 16 are fixedly installed at the bottom of the arc-shaped reflector 1. The stabilizing rod 7 cooperates with the J-shaped placement buckles 16. A strong magnet 17 is provided at the bottom inside the J-shaped placement buckle 16. The strong magnet 17 cooperates with the stabilizing rod 7. The stabilizing rod 7 is made of metal and can be fixed by the strong magnet 17. After the stabilizing rod 7 is removed from both sides of the arc-shaped rotating rod 5, it is placed inside the J-shaped placement buckle 16 and can be fixed by the strong magnet 17.

[0025] Guide rods 15 are fixedly installed on both sides of the top of the arc-shaped pressure plate 13. The guide rods 15 are slidably connected to the limiting frame 11. The guide rods 15 can limit and guide the arc-shaped pressure plate 13, so that when the arc-shaped pressure plate 13 rotates and moves up and down through the threaded rod 12, the arc-shaped pressure plate 13 will not rotate with it, thus avoiding the situation where the rotation causes angular deviation and fails to press and fix the heating tube 2.

[0026] A limiting baffle 18 is provided on the inner side of the J-type placement buckle 16; wherein the limiting baffle 18 is elastic and can limit the stabilizing pull rod 7 from the upper inner side of the J-type placement buckle 16.

[0027] The barbecue box 3 has a pull handle 19 on one side; the pull handle 19 makes it easy to insert the barbecue box 3 into the heating tube 2 for grilling and other operations, and after the food is cooked, it is easy to pull out the barbecue box 3 to take out the food.

[0028] Limiting plates are provided at both ends of the arc-shaped rotating rod 5 and on one side of the adapter ear 4. The limiting plates ensure the stability of the arc-shaped rotating rod 5 as it rotates within the adapter ear 4, preventing the arc-shaped rotating rod 5 from separating from the adapter ear 4.

[0029] An anti-slip sleeve is provided on the outer side of the arc-shaped rotating rod 5; the anti-slip sleeve improves the stability of the arc-shaped reflector 1 when supported by the arc-shaped rotating rod 5.

[0030] In summary, when using this portable concentrating solar oven, after rotating the arc-shaped rotating rod 5 below the arc-shaped reflector 1, remove the stabilizing rod 7 from the inside of the J-shaped buckle 16. First, connect one end of the stabilizing rod 7 to the threaded hole 6 on one side of the arc-shaped rotating rod 5 using the connecting bolt 8. Then, thread the other end of the stabilizing rod 7 to the threaded hole 6 on the upper side of the other arc-shaped rotating rod 5 using another connecting bolt 8. This completes the installation and fixation of the stabilizing rod 7. After both stabilizing rods 7 are installed, a tensile force is generated in the middle of the two arc-shaped rotating rods 5, improving their unfolding stability. Then, place the heating tube 2 inside the arc-shaped placement groove 10 on the top of the two brackets 9. Then, turn the handle 14 to make the threaded rod 12 move down through the thread, causing the arc-shaped pressure plate 13 to press down. The arc-shaped pressure plate 13 can then press and fix the heating tube 2 from the top into the arc-shaped placement groove 10, thus completing the fixation of the heating tube 2. Then, place the food to be grilled into the barbecue box 3 and insert the barbecue box 3 into the heating tube 2. Then, through the characteristic of the arc-shaped rotating rod 5 and the adapter ear 4 rotating connection, adjust the angle of the arc-shaped reflector 1 according to the needs so that the arc-shaped reflector 1 concentrates and refracts the light to the outside of the heating tube 2, thus heating the food. After the heating tube 2 is used up, the threaded rod 12 can be moved upward by reversing the handle 14, thereby moving the arc-shaped pressure plate 13 upward to release the restriction on the heating tube 2. The heating tube 2 can then be removed from the arc-shaped placement groove 10 for cleaning. After the overall use is completed, the cleaned heating tube 2 is fixed on the bracket 9. The stabilizing pull rod 7 and connecting bolt 8 are then removed from both sides of the arc-shaped rotating rod 5. The stabilizing pull rod 7 is then placed inside the J-shaped placement buckle 16 and fixed by the strong magnet 17. Finally, the arc-shaped rotating rod 5 is rotated around the adapter ear 4 to rotate above the arc-shaped reflector 1. The two arc-shaped rotating rods 5 then form a lifting handle, and the arc-shaped reflector 1 can then be lifted and carried by the arc-shaped rotating rod 5.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
