Description

Technical Field

[0001] This utility model relates to the field of home appliance technology, and in particular to a dual-channel oven structure. Background Technology

[0002] An oven is a common kitchen appliance, primarily used to heat and bake food using radiant heat from electric heating elements, producing a variety of delicious foods such as bread, cakes, and roasted meats. A dual-channel oven is a product with structural optimizations based on a regular oven. "Dual-channel" refers to the two independent hot air circulation channels inside the oven. This results in more even heat distribution, more efficient and comprehensive heating of food, effectively improving the quality of baked and roasted foods and reducing problems such as uneven heating leading to localized burning or undercooking.

[0003] A dual-channel oven consists of a heating element, a dual-channel heat circulation system, a temperature control system, and a cabinet. The heating element comprises heating tubes and reflectors. Heating tubes, typically made of stainless steel or quartz, are the core heat-generating component and are divided into upper and lower heating tubes, which can operate independently or simultaneously to provide the necessary heat for baking. The reflectors, usually made of metal, are installed behind or around the heating tubes to reflect the heat into the oven, improving heat utilization and ensuring more even heat distribution. The dual-channel hot air circulation system consists of dual fans and air ducts. The dual fans are located on the upper / lower or left / right sides inside the oven, each... It is equipped with a fan, and the air duct includes an intake duct and an exhaust duct, which are generally made of high-temperature resistant plastic or metal. The temperature control component is a temperature sensor, which is mostly a thermocouple or thermistor, and is usually installed inside the oven to monitor the temperature inside the oven in real time and feed the temperature signal back to the controller. The cabinet components are the inner liner and the outer shell. The inner liner is generally made of stainless steel or enamel, which has good high-temperature resistance and corrosion resistance. It is the space inside the oven that directly holds food, and its shape and size determine the oven's capacity and baking effect. The outer shell is usually made of cold-rolled steel plate or aluminum alloy, which protects the internal components and supports the entire oven.

[0004] In existing technologies, some dual-channel ovens integrate the dual fans with other components to ensure the stability and sealing of the fan during operation. This makes maintenance more complex and time-consuming, requiring maintenance personnel to spend more time and effort to complete the repairs. The high level of technical expertise required due to the difficulty of operation undoubtedly increases labor costs. Therefore, a dual-channel oven structure is proposed to solve the above problems. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 3 and Figure 4 This utility model provides an embodiment of a dual-channel oven structure, including a shell 1, which is the basic part of the entire device. A protective cover 2 is fixedly connected to the top of the shell 1, protecting the internal mechanical structure from damage. A connecting plate 3 is provided on the top of the protective cover 2, connecting the middle part of the heat dissipation assembly. Push plates 6 are slidably connected to both sides of the protective cover 2. Moving rods 7 are fixedly connected to the adjacent sides of the two push plates 6. The push plates 6 receive the pushing force of the operator, thereby driving the moving rods 7 to move. Moving blocks 8 are fixedly connected to the adjacent sides of the two moving rods 7. Connecting blocks 10 are fixedly connected to the top of the two moving blocks 8, receiving the moving rods 7. The pushing force drives the connecting block 10 to move. A spring 9 is fixedly connected to the adjacent side of the two moving blocks 8. The spring 9 receives the pushing force of the moving blocks 8 and moves accordingly. Two fixed plates 12 are fixedly connected to the top of the connecting plate 1 3. A connecting plate 13 is fixedly connected to the opposite side of the two fixed plates 12. A fixed plate 14 is fixedly connected to the bottom of the two connecting plates 13. The force of the moving connecting plate 1 3 drives the connecting plate 13 and the fixed plate 14 to move. A limit plate 15 is fixedly connected to the adjacent side of the two fixed plates 14. The limit plate 15 slides inside the connecting block 10. A heat dissipation component for heat dissipation when the equipment is overheated is fixedly connected to the top of the outer shell 1.

[0033] Reference Figure 1 and Figure 2The heat dissipation assembly includes two heating plates 19, with adjacent sides of the two heating plates 19 fixedly connected to the left and right sides of the outer casing 1. A sensor 20 is fixedly connected to the top of the heating plate 19, and two connecting lines 21 are fixedly connected to the top of the sensor 20. A transmission plate 22 is fixedly connected to the top of the two connecting lines 21. A fixing plate 23 is fixedly connected to the left side of the transmission plate 22. A fan 24 is fixedly connected inside the fixing plate 23. The sensor 20 receives the heat transferred from the heating plate 19 and transmits the signal to the connecting lines 21. The connecting lines 21 then transmit the signal to the transmission plate 22, causing the fan 24 to dissipate heat within the fixing plate 23.

[0034] Reference Figures 1 to 3 A motor 4 is rotatably connected to the top of connecting plate 3, and a crossbar is fixedly connected to the bottom of connecting plate 3. A fan 18 is fixedly connected to the bottom of the crossbar. The outside of the crossbar is rotatably connected to the inner wall of the protective cover 2. The motor 4 drives the crossbar to rotate, thereby causing the crossbar to drive the fan 18 to rotate. An inner shell 26 is fixedly connected to the inner wall of the outer shell 1. Two filter plates 25 are fixedly connected to the inner wall of the inner shell 26. The inner shell 26 protects the internal mechanical components, and the filter plates 25 filter out impurities remaining in the hot air. The outside of the fixed plate 14 is slidably connected to the inner wall of the protective cover 2, and the outside of the limiting plate 15 is slidably connected to the inside of the connecting block 10. The fixed plate 14 receives the pushing force of connecting plate 2 13, thereby... The connecting block 10 moves along with the moving block 8, so that its limiting plate 15 is slidably connected to the inside of the connecting plate. The two springs 9 are fixedly connected to the adjacent side of the partition plate 5. The upper and lower sides of the two partition plates 5 are fixedly connected to the inner wall of the protective cover 2. The partition plates 5 separate the driving component and the air dissipation component. The top of the outer shell 1 is fixedly connected to two air outlets 16 and two air inlets 17. The air inlets 17 allow air to enter the equipment, and the air outlets circulate air. The outside of the moving block 8 is slidably connected to a fixing plate 11. The upper and lower sides of the fixing plate 11 are fixedly connected to the inner wall of the protective cover 2. The fixing plate 11 allows the moving block 8 to slide stably in a straight line.

[0035] Working principle: When the ventilation assembly of the equipment needs to be disassembled, the operator pushes the push plate 6 to move the moving rod 7, which in turn moves the moving block 8, causing the spring 9 to compress and thus moving the connecting block 10. This causes the limiting plate 15 to disengage from the connecting plate, allowing the fan 18 to be disassembled. Releasing the push plate 6 releases the force of the spring 9, returning it to its original position. The new ventilation assembly is then placed into the protective cover 2, allowing the limiting plate 15 to re-enter the connecting block 10. This achieves rapid disassembly of the ventilation assembly, significantly shortens maintenance time, reduces maintenance difficulty and cost, thereby improving oven efficiency and extending equipment life.

[0036] When the required heating temperature of the equipment is too high, the sensor 20 receives a signal that the heat from the heating plate 19 is higher than the critical value of the oven. The signal is then transmitted to the transmission plate 22 via the connecting line 21. Under the action of the transmission plate 22, the fan 24, fixed by the fixing plate 23, continuously dissipates heat from the heating component. In addition, this prevents the equipment from degrading in performance and shortening its lifespan due to overheating, thereby ensuring its stable operation and reducing the cost of fault repair.

[0037] 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.
