Abstract
Description
Technical Field
[0001] This utility model relates to the field of food processing equipment technology, and in particular to an energy-saving bread baking oven. Background Technology
[0002] In the food processing industry, bread, as a popular baked good, relies heavily on the baking process. With increasing energy scarcity and growing environmental awareness, developing highly efficient and energy-saving bread baking equipment has become a crucial direction for the industry's development. Energy-saving bread ovens not only reduce production costs for businesses but also align with the principles of sustainable development, playing a significant role in promoting the green transformation of the food processing industry.
[0003] Currently, most traditional bread ovens, in terms of mechanical structure and technical principles, use a single heating element to heat the oven chamber, with temperature adjusted manually or through simple temperature control devices. The oven body typically consists of an outer shell, a heating chamber, and an oven door, with the heating element located on the side walls or bottom of the heating chamber. During operation, the heat generated by the heating element naturally convections within the oven chamber, achieving the baking of the bread. This structure and technical principle are relatively simple, primarily relying on the continuous heating of the heating element to maintain the oven temperature, lacking an effective mechanism for heat management and recovery.
[0004] However, traditional bread ovens suffer from heat loss during actual use. Due to poor insulation and a lack of effective heat recovery measures, a significant amount of heat is lost to the external environment through the oven walls, door gaps, and exhaust ducts. This leads to energy waste, increases production costs, and negatively impacts the working environment. Furthermore, to maintain the oven temperature, the heating elements need to be frequently started or run at high power for extended periods, further exacerbating energy consumption. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides an energy-saving bread oven, which aims to improve the problem of energy waste caused by the large amount of heat loss to the outside during the operation of traditional bread ovens.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an energy-saving bread oven, including an outer shell, heating wires arranged on both sides inside the outer shell, an energy-saving component arranged on the top of the outer shell, an adjustment component arranged inside the outer shell, and a sealing component arranged on the outer wall of the outer shell;
[0007] The energy-saving component includes a heating element disposed above the outer casing. An air pump is fixedly connected to the upper surface of the outer casing.

[0009] Furthermore, the sealing assembly includes a sealing door, the inner wall of which is disposed on the outer wall of the outer casing, a handle is fixedly connected to the outer wall of the sealing door, and a rotating shaft is disposed on one side of the outer wall of the outer casing, the inner wall of which is fixedly connected to the outer wall of the sealing door.
[0010] Furthermore, the outer walls of the fixing rods are all threadedly connected to the inner walls of the sliding shaft and the rotating column, and the sliding shaft is used to fix the sliding shaft.
[0011] Furthermore, the outer wall of the limiting block is slidably connected to the inside of the limiting box, and the baking rack and the limiting box are used to fix the baking tray.
[0012] Furthermore, one end of the delivery pipe is fixedly connected to the other end of the heating pipe, which is used to heat the water inside the water tank.
[0013] Furthermore, one end of the exhaust pipe is fixedly connected to the inner wall of the outer shell, and the exhaust pipe is used to extract the hot air inside the outer shell.
[0014] Furthermore, one end of the vent pipe is fixedly connected to the inner wall of the outer shell, and the vent pipe is used to transport the dried hot air into the interior of the outer shell.
[0015] This utility model has the following beneficial effects:
[0016] 1. In this utility model, when the heating wire inside the outer shell is heating, the air pump draws hot air from the oven and sends it into the heating tube to heat the water tank.

[0028] Reference Figures 1-5 An embodiment of this utility model is provided: an energy-saving bread oven, including an outer shell 1, heating wires 11 arranged on both sides inside the outer shell 1, an energy-saving component arranged on the top of the outer shell 1, an adjustment component arranged inside the outer shell 1, and a sealing component arranged on the outer wall of the outer shell 1;
[0029] The energy-saving component includes a heating element 13, which uses extracted hot air to heat the water in the water tank 8, achieving heat exchange. This is a key structure for heat energy conversion within the energy-saving component. The water tank 8 stores water, which is heated by the heating element 13 to generate steam. Simultaneously, water is replenished through the inlet pipe 25 and drained through the outlet pipe 14 to maintain a stable water level and ensure continuous operation of the heat recovery system. The heating element 13 is positioned above the outer casing 1. An air pump 5 is fixedly connected to the upper surface of the outer casing 1. An air extraction pipe 6 is fixedly connected to the input end of the air pump 5. A delivery pipe 7 is fixedly connected to one end of the air extraction pipe 6.

[0030] Specifically, when the heating wire 11 inside the outer shell 1 is heating, the air pump 5 draws hot air from the furnace through the air extraction pipe 6 and sends it into the heating tube 13 through the delivery pipe 7. The heating tube 13 heats the water in the water tank 8, and the hot air is discharged through the exhaust pipe 9. The water vapor generated by heating enters the drying box 23 through the air supply pipe 24 for drying, and is finally sent back to the inner shell 1 for circulation through the air outlet pipe 26. The water tank 8 is replenished with water through the water inlet pipe 25 and drained through the drain pipe 14.
[0031] Reference Figures 1-7 The adjustment assembly includes a fixed rod 19, which is located inside the outer casing 1. A protective box 10 is fixedly connected to the upper surface of the outer casing 1. A motor 12 is located inside the protective box 10. A rotating column 22 is fixedly connected to the output end of the motor 12. A sliding shaft 18 is slidably connected to the outer wall of the rotating column 22. A baking rack 16 is fixedly connected to the outer wall of the sliding shaft 18. The rack 16 is connected to the fixed rod 19 via the sliding shaft 18 and can be raised and lowered along the fixed rod 19. Its function is to place the baking tray 20. The hollow inner wall facilitates heat transfer, allowing the bread to be heated evenly. The distance between the baking racks 16 can be adjusted according to the size of the bread to meet different baking needs. A limiting box 17 is fixedly connected to the outer wall of the baking rack 16. A baking tray 20 is provided on the upper surface of the baking rack 16 for placing bread. The tray 20 is fixed to the baking rack 16 by the cooperation of the limiting block 21 and the limiting box 17, providing a support platform for bread baking and allowing the bread to bake evenly. During the process, the baking tray 20 is kept in a stable position. A limiting block 21 is fixedly connected to the outer wall of the baking tray 20. The sealing assembly includes a sealing door 2. The inner wall of the sealing door 2 is set on the outer wall of the outer shell 1. A handle 4 is fixedly connected to the outer wall of the sealing door 2. A rotating shaft 3 is set on one side of the outer wall of the outer shell 1. The inner wall of the rotating shaft 3 is fixedly connected to the outer wall of the sealing door 2. The outer walls of the fixing rod 19 are threadedly connected to the inner walls of the sliding shaft 18 and the rotating column 22. The sliding shaft 18 is used to fix the sliding shaft 18. The outer wall of the limiting block 21 is slidably connected to the inside of the limiting box 17. The baking rack 16 and the limiting box 17 are used to fix the baking tray 20. One end of the conveying pipe 7 is fixedly connected to the other end of the heating pipe 13. The heating pipe 13 is used to transfer water from the hot water tank 8. One end of the suction pipe 6 is fixedly connected to the inner wall of the outer shell 1. The suction pipe 6 is used to extract the hot air from the inside of the outer shell 1. One end of the exhaust pipe 26 is fixedly connected to the inner wall of the outer shell 1. The exhaust pipe 26 is used to transport the dried hot air to the inside of the outer shell 1.
[0032] Specifically, the motor 12 is installed inside the protective box 10. After the motor 12 is started, the rotating column 22 at its output end drives the sliding shaft 18 to move. Since the fixed rod 19 is threadedly connected to the sliding shaft 18 and the rotating column 22, the sliding shaft 18 drives the baking rack 16 to move along the fixed rod 19, thereby adjusting the height of the baking rack 16. The baking tray 20 is fixed on the baking rack 16 by the limiting block 21 on the outer wall cooperating with the limiting box 17 on the baking rack 16, which makes it easy to place and remove bread. The hollow inner wall of the baking rack 16 is conducive to heat transfer, ensuring that the bread is heated evenly.
[0033] Working principle: Heating wire 11 inside the outer shell 1 works to heat the furnace. Air pump 5 draws hot air from the furnace through air extraction pipe 6 and sends it to heating tube 13 through delivery pipe 7. After heating water in water tank 8, the hot air in heating tube 13 is discharged through exhaust pipe 9. Water vapor generated after heating is sent to drying box 23 through air supply pipe 24 for drying. Finally, it is sent back to the outer shell 1 through air outlet pipe 26 for recycling. Water tank 8 can be replenished with water through water inlet pipe 25 and drained through water outlet pipe 14 to realize heat recovery and reuse.
[0034] In addition, the motor 12 is installed inside the protective box 10. After the motor 12 is started, the rotating column 22 at its output end drives the sliding shaft 18 to move. Since the fixed rod 19 is threadedly connected to the sliding shaft 18 and the rotating column 22, the sliding shaft 18 drives the baking rack 16 to move along the fixed rod 19, thereby adjusting the height of the baking rack 16. This allows the distance between the baking racks 16 to be adjusted according to the size of the bread. The baking tray 20 is fixed to the baking rack 16 by the limiting block 21 and the limiting box 17 on the baking rack 16, which facilitates the placement and removal of bread. The hollow inner wall of the baking rack 16 is conducive to heat transfer, ensuring that the bread is heated evenly. The sealing door 2 is installed on the outer shell 1 by the rotating shaft 3. The sealing door 2 can be opened or closed by the handle 4 to ensure the sealing of the oven.
[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
