Description

Technical Field

[0001] This invention relates to the field of oven technology, and more specifically, to an oven with low energy consumption and high heat retention. Background Technology

[0002] An oven is a device that uses high temperatures to bake and cook food. Existing oven heating methods are typically divided into electric and natural gas. For example, prior art (CN114946896B) discloses a double-layered, cross-heating, energy-saving oven with a lower chamber and an upper chamber. By placing the heating element between the lower and upper chambers, the heat radiated by the heating element to both sides can be better absorbed by the food in both chambers, avoiding energy waste caused by excessive heat absorption by the oven and achieving energy saving.

[0003] However, the heat transfer of the heating tube includes not only the vertical direction but also the horizontal direction. Due to the distribution of the lower and upper boxes, only the heat in the vertical direction can be utilized, while the heat in the horizontal direction is not utilized, resulting in a low heat utilization rate.

[0004] Meanwhile, the grill rack is placed in the rotating slot via a rotating block. When placing or removing food, the grill rack needs to be taken out of the oven, which is cumbersome and takes a long time. Since the oven door is open for a long time, a lot of heat is easily lost from the oven, which requires raising the internal temperature for subsequent baking operations, thus increasing energy consumption and being detrimental to energy conservation.

[0005] Given the shortcomings of the existing technology, it is necessary to further improve it in order to meet the actual use case. Summary of the Invention

[0006] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0007] Therefore, the purpose of this invention is to provide a low-energy-consumption, high-heat-insulation oven.

[0008] The present invention provides a low-energy-consumption and high-heat-insulation oven, including an oven body, an infrared baking lamp located at the center of the oven body, and a fixed frame located inside the oven body;

[0009] The furnace body is equipped with a first lifting mechanism for driving the fixed frame to rise and fall. The bottom of the furnace body is open and bolted to a base plate.

[0010] The base plate has multiple second through holes arranged in a ring. A rotating cylinder is connected to the wall bearing at the center of the base plate. The rotating cylinder passes through the center of the rotating plate and is welded to it. The rotating plate has multiple first through holes arranged in a ring. The rotating cylinder has threaded grooves.

[0011] The fixing frame has a central hole for the fixing plate to pass through, and the outer circular wall of the fixing plate is movably connected to the inner wall of the hole by a bearing.

[0012] A vertical rod runs through the fixed plate, and a fixing ring is welded to the top of the vertical rod. A slot for inserting a tray is provided in the lower half of the vertical rod, and a reflector is connected to the bottom of the tray via a connecting post.

[0013] A limiting plate is welded to the vertical rod, and a transmission rack is welded between the limiting plate and the fixing ring. The fixing plate has a slot for the transmission rack to pass through.

[0014] The fixed frame is provided with a rotating mechanism for driving the fixed plate to rotate, and a second lifting mechanism for driving the transmission rack to rise and fall.

[0015] A set of T-shaped guide rods runs through the fixed plate. A mounting plate is welded to the bottom end of each guide rod. A spring is fitted onto each guide rod, and both ends of the spring are welded to both the fixed plate and the mounting plate.

[0016] A threaded post that matches the threaded groove is welded to the center of the bottom surface of the mounting plate.

[0017] As a preferred technical solution:

[0018] As described above, a low-energy-consumption, high-insulation oven has multiple annularly distributed lining strips on its inner wall. These lining strips are combined to form a cylindrical shape, and the cross-section of each lining strip is triangular.

[0019] The inner lining strip is made of SIC material, and both the inner lining strip and the reflector surface are coated with a heat-reflective coating.

[0020] Through the above technical solutions, the SIC material inner lining has good thermal insulation performance. Combined with the heat-reflective coating attached to its surface, it can greatly reduce heat loss, thereby effectively achieving the effects of energy saving and energy consumption reduction.

[0021] As described above, in a low-energy-consumption, high-insulation oven, the first lifting mechanism includes a first servo motor bolted to the outer wall of the oven body, and a set of lead screws located inside the oven body.

[0022] The top end of the lead screw passes through the furnace body and is connected to the furnace body bearing, the bottom end of the lead screw passes through the fixed frame and is threadedly connected to the fixed frame, and the output shaft of the first servo motor and the top end of the lead screw are connected by chain drive.

[0023] With the above technical solution, when it is necessary to drive the fixed frame to rise or fall, the first servo motor can be powered on and run. The first servo motor drives the two lead screws to rotate synchronously through the chain drive mechanism, namely the sprocket and the chain, and then drives the fixed frame to rise or fall by driving the lead screws to rotate forward and backward.

[0024] As described above, in a low-energy-consumption, high-insulation oven, the outer frame wall of the fixed frame does not contact the inner wall of the oven, and a set of vertical guide columns runs through the fixed frame, with the top ends of the guide columns welded to the inner wall of the oven.

[0025] Through the above technical solution, the guide post and the fixed frame are linearly slidably connected. Thus, when the fixed frame moves vertically under the drive of the lead screw, a set of guide posts can improve the moving accuracy of the fixed frame and prevent the movement from deviating.

[0026] As described above, in a low-energy-consumption, high-insulation oven, the second lifting mechanism includes a first transmission gear meshing with a transmission rack. The first transmission gear is fixed to a second transmission rod by a locking pin. The second transmission rod is connected to the first transmission rod via a chain drive structure. One end of both the second and first transmission rods is connected to a fixed base shaft. The fixed base is welded and fixed to a fixed frame.

[0027] Both the first transmission rod and the lead screw are fixed with bevel gears by pins, and the bevel gears of the first transmission rod and the lead screw mesh with each other.

[0028] With the above technical solution, the second transmission rod and the first transmission rod are arranged in parallel. Through the chain drive mechanism, namely the sprocket and the chain, the second transmission rod and the first transmission rod can rotate synchronously. Since they are fixed on the fixed base, they can move synchronously with the fixed frame. When the fixed frame moves downward, it can drive the vertical rod to move downward synchronously. During this process, the first transmission gear and the transmission rack can push the vertical rod downward. In this way, within the limited range of movement of the fixed frame, the range of movement of the vertical rod is increased, ensuring that the vertical rod can drive the tray to move out of the furnace body 1. The structure is reasonable.

[0029] As described above, in a low-energy-consumption, high-insulation oven, the rotating mechanism includes a second servo motor bolted to a fixed frame, and a groove formed on the surface of the fixed frame. A second transmission gear is disposed within the groove, and the output shaft of the second servo motor extends into the groove and is secured to the second transmission gear with a locking pin.

[0030] The second transmission gear meshes with the gear ring, which is sleeved and fixed on the outer circular wall of the fixed plate.

[0031] With the above technical solution, when the second servo motor is powered on, it drives the second transmission gear to rotate. The second transmission gear drives the fixed plate to rotate axially through the gear ring. The fixed plate drives the tray to rotate through the vertical rod. This allows the tray to rotate around the infrared baking lamp, which can fully contact the heat and improve the heat utilization rate.

[0032] As described above, in a low-energy-consumption, high-insulation oven, the vertical rods are arranged in groups of three and distributed in a ring, and the limiting plates on the vertical rods are circular.

[0033] The diameter of the limiting plate is larger than the inner diameter of the first through hole, the inner diameters of the first through hole and the second through hole are the same, and the inner diameter of the first through hole is larger than the diameter of the tray.

[0034] With the above technical solution, when the vertical rod can move the tray out of the furnace body 1, the heat inside the furnace body will be dissipated through the first and second through holes. In order to avoid a large amount of heat loss, a limit plate is set. The limit plate can block the through holes, so that only a small amount of heat will be lost during the process of placing and removing food. In this way, the energy-saving and energy consumption reduction effects can also be achieved.

[0035] As described above, in a low-energy-consumption and high-insulation oven, a fixed cylinder is welded to the inner wall of the top of the oven body, and a rotating ring is connected to the inner circular wall bearing of the fixed cylinder. The rotating ring and the fixed ring have the same size and are coaxial.

[0036] Magnet blocks are embedded on the opposite sides of both the rotating ring and the fixed ring, and the opposite sides of the magnet blocks on the rotating ring and the fixed ring are opposite magnetic poles.

[0037] With the above technical solution, when the fixed plate moves the tray into the furnace body through the vertical rod, the limiting plate on the vertical rod will approach the rotating ring. Under the magnetic force of the magnet, the rotating ring and the fixed ring will be attracted together. In this way, the vertical rod can be fixed to prevent displacement. In this way, when the vertical rod rotates with the fixed plate, the transmission rack and the first transmission gear will not experience tooth breakage.

[0038] As described above, in a low-energy-consumption, high-insulation oven, the tray is porous, the top of the connecting column is connected to a bearing at the center of the tray, and the bottom of the connecting column is welded to the top surface of the reflector.

[0039] The reflector has a conical structure, and a cylindrical protrusion extends vertically downward from the bottom surface of the reflector. A collar is fitted onto the protrusion and welded to it. Multiple partitions arranged in a ring are welded to the outer circular wall of the protrusion. Two adjacent partitions, together with the bottom surface of the reflector and the surface of the collar, form a fan-shaped groove.

[0040] With the above technical solution, multiple fan-shaped slots are distributed. When the reflector moves in a circular motion with the tray, air from inside the furnace is poured into the fan-shaped slots, which in turn drives the reflector to rotate slowly through the airflow.

[0041] The reflector absorbs the heat emitted by the infrared baking lamp and radiates it out through the heat-reflecting film. The radiated heat can heat the bottom of the food, thereby improving the baking effect. At the same time, the reflector rotates to ensure that its surface is heated evenly, so that the radiated heat can evenly cover the bottom of the food, thus improving the heating uniformity of the bottom of the food.

[0042] In the low-energy-consumption, high-insulation oven described above, the diameter of the collar is larger than the diameter of the reflector, and the surface of the collar has an inverted conical structure.

[0043] Through the above technical solution, the design of the collar allows for the collection of a small amount of oil stains generated during the baking of meat products. These oil stains drip down through the holes in the tray, flow down the surface of the reflector, and finally fall onto the collar and flow into the fan-shaped groove, thus achieving the collection of oil stains and ensuring the cleanliness of the oven.

[0044] The beneficial effects of the low-energy-consumption, high-heat-insulation oven of the present invention are as follows:

[0045] The present invention is provided with vertical rods. Three vertical rods, together with their slots, can support the tray. In this way, the three vertical rods and multiple trays are combined to form a food placement mechanism. Multiple food placement mechanisms are provided and distributed around the infrared baking lamp. The infrared baking lamp is set vertically, and its heat can be evenly transferred outward in 360°. In this way, when the tray moves in a circle with the vertical rods, it can come into uniform contact with the heat, thereby improving the heat utilization rate.

[0046] The present invention is equipped with an inner lining strip and a reflector. The inner lining strip can radiate heat back through a heat-reflective coating, which greatly reduces heat loss, thereby achieving heat preservation and energy saving, and greatly reducing energy consumption. The reflector can radiate heat to the bottom of the tray through a heat-reflective coating, so that the part of the food in contact with the tray can also be fully heated, improving the baking efficiency of the food.

[0047] This invention features a base plate with a rotating plate on it. The rotating plate causes the first and second through holes to be offset and aligned. When the vertical rod moves the tray downwards, the first and second through holes align. At this time, the vertical rod moves the tray out of the oven through the through holes, facilitating the placement and removal of food. During this process, the through holes are blocked by a limiting plate, thus preventing heat loss, further improving the technical effect, and reducing the energy consumption of the infrared baking lamp.

[0059] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0060] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0061] This invention provides a technical solution: a low-energy-consumption, high-insulation oven.

[0062] like Figure 1-2 As shown, it includes a furnace body 1 and an infrared baking lamp 3 located at the center of the furnace body 1, as well as a fixed frame 4 located inside the furnace body 1. Multiple inner lining strips 101 arranged in a ring are provided on the inner wall of the furnace body 1. The multiple inner lining strips 101 are combined into a cylindrical shape. The cross section of the inner lining strip 101 is triangular. The inner lining strip 101 is made of SiC material and has a heat-reflective coating on its surface.

[0063] When the infrared baking lamp 3 is powered on, it can generate heat, which will raise the temperature inside the oven body 1, thereby baking the food. Since the heat will be dissipated through the oven body 1, in order to reduce heat loss, an inner lining layer composed of inner lining strips 101 is provided, which can play a heat insulation role. At the same time, the heat reflective coating on the surface can radiate the heat back, further reducing heat loss and helping to save energy.

[0064] Meanwhile, the shape design of the inner lining strip 101 can increase the surface area of ​​the inner lining layer, which can maximize the absorption of heat and radiate the heat away, improve the heat utilization rate, and thus effectively reduce the energy consumption of the equipment.

[0065] like Figure 1 As shown, the furnace body 1 is provided with a first lifting mechanism for driving the fixed frame 4 to rise and fall. The first lifting mechanism includes a first servo motor 23 bolted to the outer wall of the furnace body 1, and a set of lead screws 24 located inside the furnace body 1. The top end of the lead screw 24 passes through the furnace body 1 and is connected to the bearing of the furnace body 1. The bottom end of the lead screw 24 passes through the fixed frame 4 and is threaded to the fixed frame 4. The output shaft of the first servo motor 23 and the top end of the lead screw 24 are connected by chain drive.

[0066] The outer frame wall of the fixed frame 4 does not contact the inner wall of the furnace body 1. A set of vertical guide columns runs through the fixed frame 4, and the top of the guide columns is welded to the inner wall of the furnace body 1.

[0067] A set of guide columns and a set of lead screws 24 are arranged in a rectangular shape. When the first servo motor 23 drives the set of lead screws 24 to rotate synchronously, the lead screws 24 can drive the fixed frame 4 to move vertically along the set of guide columns. During the movement, the fixed frame 4 will not contact the inner wall of the furnace body 1, thus avoiding damage to the inner lining strip 101 and its heat reflective coating.

[0068] like Figure 3-4 As shown, the fixed frame 4 has a central hole for the fixed plate 5 to pass through. The outer circular wall of the fixed plate 5 is movably connected to the inner wall of the hole by a bearing. The fixed frame 4 is provided with a rotating mechanism for driving the fixed plate 5 to rotate. The rotating mechanism includes a second servo motor 33 bolted to the fixed frame 4 and a groove 31 opened on the surface of the fixed frame 4. A second transmission gear 32 is provided in the groove 31. The output shaft of the second servo motor 33 extends into the groove 31 and is fixed with a pin to the second transmission gear 32. The second transmission gear 32 meshes with a gear ring 34, and the gear ring 34 is sleeved and fixed on the outer circular wall of the fixed plate 5.

[0069] After the second servo motor 33 is powered on, it can drive the fixed plate 5 to rotate axially on the fixed frame 4 through the second transmission gear 32 and the gear ring 34.

[0070] The center of the fixing plate 5 is provided with a through groove for the infrared baking lamp 3 to pass through. The infrared baking lamp 3 is suspended in the oven body 1 by a bracket, so that the rotation of the fixing plate 5 will not interfere with the infrared baking lamp 3.

[0071] like Figure 5 As shown, a vertical rod 7 runs through the fixed plate 5. The lower half of the vertical rod 7 has a slot 8 for inserting the tray 9. There are multiple groups of three vertical rods 7 arranged in a ring.

[0072] During operation, food can be placed on tray 9, and the edge of tray 9 can be inserted into slot 8 to lock and fix tray 9 to three vertical rods 7, thus securing tray 9. When the fixing frame 4 drives the fixing plate 5 to rise, the tray 9 can be lifted into the oven body 1 through the vertical rods 7. In this way, the fixing plate 5 can drive multiple sets of vertical rods 7 to rotate around the infrared baking lamp 3, so that the food on tray 9 can be heated evenly, improving the baking effect.

[0073] like Figure 1 and Figure 6 As shown, a fixed ring 15 is welded to the top of the vertical rod 7, and a fixed cylinder 18 is welded to the inner wall of the top of the furnace body 1. A rotating ring 16 is connected to the inner circular wall bearing of the fixed cylinder 18. The rotating ring 16 and the fixed ring 15 have the same size and are coaxial. A magnet block 17 is embedded on the opposite side of the rotating ring 16 and the fixed ring 15. The opposite side of the magnet block 17 on the rotating ring 16 and the fixed ring 15 are opposite magnetic poles.

[0074] When the vertical rod 7 moves into the furnace body 1 along with the fixing plate 5, the fixing ring 15 will come close to and fit with the rotating ring 16, and be attracted together by the magnetic force of the magnet block 17. Since the rotating ring 16 is a rotating structure on the fixing cylinder 18, the rotating ring 16 can rotate synchronously with the fixing ring 15. In this way, the vertical rod 7 can be limited, so that the vertical rod 7 will not have vertical displacement when it rotates with the fixing plate 5.

[0075] like Figure 1 , Figure 3 and Figure 7 As shown, a transmission rack 25 is welded between the limiting plate 6 and the fixing ring 15. The fixing plate 5 has a slot 30 for the transmission rack 25 to pass through. The fixing frame 4 is provided with a second lifting mechanism for driving the transmission rack 25 to rise and fall. The second lifting mechanism includes a first transmission gear 26 that meshes with the transmission rack 25. The first transmission gear 26 is pinned to the second transmission rod 29. The second transmission rod 29 is connected to the first transmission rod 28 through a chain transmission structure. One end of the second transmission rod 29 and the first transmission rod 28 are both connected to the fixed seat shaft. The fixed seat is welded to the fixing frame 4. The first transmission rod 28 and the lead screw 24 are both pinned to bevel gears 27. The bevel gears 27 of the first transmission rod 28 and the lead screw 24 mesh with each other.

[0076] When the first lifting mechanism moves the fixed frame 4 vertically, it drives the second lifting mechanism to move synchronously. During this process, the lead screw 24 drives the first transmission rod 28 to rotate axially on the fixed seat via the bevel gear 27. The first transmission rod 28 drives the second transmission rod 29 to rotate synchronously on the fixed seat via chain drive. The second transmission rod 29 drives the first transmission gear 26 to rotate. The first transmission gear 26 drives the transmission rack 25 to move vertically within the slot 30. In turn, the transmission rack 25 drives the vertical rod 7 to move vertically via the limiting plate 6 and the fixing ring 15.

[0077] The first lifting mechanism, in conjunction with the second lifting mechanism, can increase the range of motion of the vertical rod 7, enabling the vertical rod 7 to move the tray 9 out of the furnace body 1 or lift it completely into the furnace body 1, resulting in a reasonable structure.

[0078] The second lifting mechanism is provided in two sets and is staggered and symmetrical about the fixed frame 4. Due to the non-mirror symmetry, the first transmission gears 26 in the two sets of second lifting mechanisms rotate in opposite directions.

[0079] like Figure 1 and Figure 8As shown, the bottom of the furnace body 1 is open and bolted to a base plate 2. The base plate 2 has multiple annularly distributed second through holes 205. A rotating cylinder 201 is connected to the wall bearing at the center of the base plate 2. The rotating cylinder 201 passes through the center of a rotating plate 203 and is welded to the rotating plate 203. The rotating plate 203 has multiple annularly distributed first through holes 204, and the rotating cylinder 201 has threaded grooves 202.

[0080] A set of T-shaped guide rods 21 runs through the fixed plate 5. The bottom end of the guide rods 21 is welded to the mounting plate 19. A spring spring 22 is sleeved on the guide rods 21. Both ends of the spring spring 22 are welded to the fixed plate 5 and the mounting plate 19. A threaded post 20 matching the threaded groove 202 is welded to the center of the bottom surface of the mounting plate 19.

[0081] When the fixed frame 4 vertically moves the fixed plate 5 vertically, the fixed plate 5 moves the mounting plate 19 via the guide rod 21. The mounting plate 19 then moves the threaded post 20 downward and inserts it into the threaded groove 202. During the vertical movement, the threaded post 20 pushes the rotating cylinder 201 to rotate axially via the thread. This causes the rotating cylinder 201 to rotate the rotating plate 203 by a certain angle, aligning the first through hole 204 and the second through hole 205.

[0082] During the above process, the vertical rod 7 and the tray 9 on it are still inside the oven body 1. When the fixing plate 5 continues to move vertically, the threaded column 20 has been fully inserted into the rotating cylinder 201. At this time, the rotating cylinder 201 can no longer rotate, and the fixing plate 5 will continue to move along the guide rod 21 and compress the elastic spring 22. In this way, the fixing plate 5 can drive the vertical rod 7 to move out of the through hole, and the vertical rod 7 drives the tray 9 on it to move out of the oven body 1, which makes it easy to remove the baked food and put the food back in place.

[0083] like Figure 5 As shown, a limiting plate 6 is welded to the vertical rod 7. The limiting plate 6 on the vertical rod 7 is circular. The diameter of the limiting plate 6 is larger than the inner diameter of the first through hole 204. The inner diameters of the first through hole 204 and the second through hole 205 are the same. The inner diameter of the first through hole 204 is larger than the diameter of the tray 9.

[0084] When the vertical rod 7 moves the tray 9 on it out of the oven body 1, the limiting plate 6 will fit with the rotating plate 203, which can block the first through hole 204, preventing heat loss during the process of picking up and putting down food, which is beneficial to the overall energy saving effect.

[0085] like Figure 5 and Figure 9As shown, a reflector plate 10 is connected to the bottom of the tray 9 via a connecting post 11. The surface of the reflector plate 10 is coated with a heat-reflective coating. The tray 9 is porous. The top of the connecting post 11 is connected to a bearing at the center of the tray 9. The bottom of the connecting post 11 is welded to the top surface of the reflector plate 10. The reflector plate 10 has a conical structure. A cylindrical protrusion 12 extends vertically downward from the bottom surface of the reflector plate 10. A collar 13 is fitted onto the protrusion 12 and welded to it. Multiple partitions 14 arranged in a ring are welded to the outer circular wall of the protrusion 12. Two adjacent partitions 14, the bottom surface of the reflector plate 10, and the surface of the collar 13 enclose a fan-shaped groove. The diameter of the collar 13 is larger than the diameter of the reflector plate 10. The surface of the collar 13 has an inverted conical structure.

[0086] Since multiple fan-shaped grooves are formed between the reflector 10 and the collar 13, when the reflector 10 rotates around the infrared baking lamp 3 with the tray 9, the air in the oven body 1 will be injected into the fan-shaped grooves, and then the airflow will push the reflector 10 and the collar 13 to rotate slowly as a whole. In this way, the reflector 10 is a rotating structure at the bottom of the tray 9 through the connecting column 11.

[0087] Since the bottom of the food is in contact with the tray 9, the bottom of the food heats up slowly. Therefore, a reflector 10 is provided. The reflector 10 can absorb the heat emitted by the infrared baking lamp 3 and radiate it upward through the heat-reflective coating. Furthermore, the continuous rotation of the reflector 10 and the porous design of the tray 9 can ensure that the bottom of the food is heated evenly, thereby improving the baking effect of the food.

[0088] The heat-reflective coating is a polyacrylic acid coating, which has been disclosed in the prior art CN109233493B and will not be described in detail here.

[0089] The heat-reflective coating can also be made of other materials with heat-reflective properties, and there are no limitations on this.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium.
