Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of oven, concretely relates to an oven with uniform baking. BACKGROUND

[0002] In many fields such as industrial production, food processing, electronic manufacturing, oven is an indispensable equipment for heating, drying, curing, baking and other treatments of various materials and products. However, traditional ovens have many problems in practical application, which are analyzed as follows:

[0003] In terms of baking uniformity, traditional ovens face severe challenges. The layout of heating elements in many traditional ovens is not reasonable enough, resulting in uneven heat distribution inside the inner tank. Some ovens only set heating elements at the bottom or top, making the heated objects have obvious differences in vertical direction, and it is easy to cause over-baking at the bottom or top while the middle part is not baked. Even if some ovens set heating elements on multiple sides, due to factors such as element power and spacing, they still cannot achieve ideal uniform heating effect. In industrial production, for some materials processing with extremely high requirements on temperature uniformity, such as drying of precision electronic components, coating curing of optical lenses, etc., the uneven heating of traditional ovens may cause problems such as product deformation and unstable performance, reducing product pass rate and increasing production cost.

[0004] Heat efficiency and energy saving are also a big shortcoming of traditional ovens. The structure design of the shell and inner tank of traditional ovens often ignores the problem of heat loss, lacking effective insulation measures. Heat is easily conducted to the surrounding environment through the shell, not only wasting energy, but also increasing the temperature of the surrounding environment of the oven, affecting the working comfort of the operators, and even causing safety hazards in some high-temperature environments.

[0005] In addition, traditional ovens have deficiencies in the design of ventilation system, with poor air circulation, which cannot fully utilize heat, resulting in a large amount of heat being lost without being effectively utilized, further reducing heat efficiency and increasing energy consumption. In today's society, where energy saving and emission reduction are increasingly valued, the high energy consumption problem of traditional ovens needs to be solved urgently.

[0006] In terms of air circulation and environmental control, traditional ovens have many deficiencies. Many traditional ovens have imperfect ventilation systems, lacking effective supply of fresh air and timely discharge mechanism of waste gas. During the baking process, especially when dealing with items containing volatile substances, such as paint drying, post-processing of plastic injection molded parts, etc., harmful gases and odors accumulate in the oven, not only affecting product quality, but also causing serious harm to the health of operators. At the same time, poor air circulation will cause unstable air pressure in the oven, affecting heat transfer and baking effect, further reducing product quality. SUMMARY

[0007] To solve the problems raised in the background art, the utility model provides a baking oven which is simple in structure, high in baking uniformity and thermal efficiency, convenient to operate and further improves the performance and practicality of the baking oven.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a baking oven which is simple in structure, high in baking uniformity and thermal efficiency, convenient to operate and further improves the performance and practicality of the baking oven.

[0009] As a further elaboration of the technical scheme:

[0010] Preferably, the shell and the inner container are in the shape of a cuboid, and the box further comprises a heat preservation layer filled in the first containing space, for reducing heat loss, improving the thermal efficiency of the baking oven and reducing energy consumption.

[0011] Preferably, the outer periphery of the end of the circulation fan at the top end of the inner container is provided with a flow guide mechanism, and the flow guide mechanism comprises a flow guide plate and a mounting seat, the mounting seat comprises two and is in the shape of a prototype, and the flow guide plate comprises a plurality of and is in the shape of a straight-leaf fan blade, the plurality of flow guide plates are vertically and uniformly arranged between the two mounting seats and are distributed in a radial manner in the same axial plane, for forming a spiral upward airflow in the inner container and ensuring that the elements to be dried on the shelves are uniformly dried.

[0012] Preferably, the utility model further comprises a temperature control system which is arranged at the front end right side of the circulation fan at the top of the shell and is connected with the inner periphery of the inner container, for detecting the temperature of the inner periphery of the inner container in real time.

[0013] Preferably, the utility model further comprises a control system which is arranged at the right end of the shell, is electrically connected with the temperature control system and the heating element, and controls whether the heating element is heated or not through the information fed back by the temperature control system.

[0014] Preferably, the front side of the box is provided with a baking oven door, and the right end of the baking oven door is movably connected with the box through a hinge, for opening or closing the box.

[0015] Preferably, the fresh air valve is a one-way fresh air valve, and the exhaust valve is a one-way exhaust valve.

[0016] Preferably, universal wheels are arranged around the lower end of the box body, and the universal wheels are used to move the box body.

[0017] Compared with the prior art, the utility model has the beneficial effects that:

[0018] Firstly, the heating elements are uniformly distributed around the inner container, ensuring uniform heat generation inside the inner container. During the baking process, the drying elements can receive relatively balanced heat from all directions, effectively avoiding local overheating or overcooling. Whether it is a small electronic component or a large industrial product, it can be baked in a stable temperature environment, making the overall product evenly heated and improving the consistency of baking quality.

[0019] Secondly, the flow guide mechanism arranged at the outer periphery of the end of the circulating fan at the top end of the inner container further improves the baking uniformity. A plurality of straight-leaf fan-shaped guide plates are evenly distributed between the two circular mounting seats in a slanting vertical manner. Under the action of the circulating fan, air forms a spiral upward airflow in the inner container. This unique airflow circulation mode enables hot air to more fully contact the drying elements on the shelf, ensuring that each part of each element receives uniform heat transfer.

[0020] Thirdly, the heat preservation layer filled between the shell and the inner container effectively reduces heat loss. During the operation of the oven, the heat preservation layer can prevent heat from being dissipated to the external environment, allowing more heat to be concentrated inside the inner container and improving the thermal efficiency of the oven. This not only shortens the baking time and reduces energy consumption, but also reduces the thermal impact on the surrounding environment.

[0021] Fourthly, the circulating fan, fresh air valve and exhaust valve in the ventilation system work together to optimize heat utilization. The circulating fan realizes rapid circulation of air around the inner container, allowing heat to be quickly and evenly distributed throughout the inner container space, avoiding heat accumulation in local areas. The fresh air valve delivers fresh air into the inner container, and the exhaust valve exhausts air from the inner container, ensuring air circulation in the oven.

[0022] Fifthly, the temperature control system detects the temperature around the inner container in real time and feeds back the temperature information to the control system. The control system accurately controls the heating of the heating elements according to the preset temperature parameters and feedback information, achieving precise control of the temperature in the oven. The oven door designed by folding the front side of the box body is convenient for users to open and close the box body.

[0023] Sixthly, the left and right shelves each include a plurality of groups in one-to-one correspondence, which are matched with each other for containing elements to be dried. The design of the plurality of groups of shelves provides abundant placement space, and users can flexibly adjust according to the number, size and shape of the elements to be dried. Whether small elements are batch baked or large products of different sizes are simultaneously processed, a suitable shelf combination mode can be found, and the versatility and practicality of the oven are improved.
