[0003] Among them, the working principle of the electric oven is to use the radiant heat emitted by the electric heating element to bake food. The air fryer uses high-speed air circulation technology, and the unique combination of fast-circulating hot air and internal spiral patterns makes the cooking effect reach the effect and taste of fried food. Since the air fryer oven combines the air frying function in the oven, and this type of oven product limits the flow of hot air, the wind speed in the baking chamber is low, and the flow direction of the hot air is unclear, resulting in poor baking effect of food; in addition, the heat generated by the heating tube dissipates to the surroundings, and does not gather on the food part in the center of the baking chamber, making the temperature in the baking chamber uneven, the baking time longer, and the air-fried food becomes burnt and dry, and the taste becomes worse.

[0004] Therefore, there is an urgent need for a frying oven with uniform temperature distribution, uniform food color and good taste. Summary of the invention

[0026] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0027] like Figure 1-Figure 4As shown, a high-speed air frying oven comprises a main body 1 provided with a baking cavity, an air inlet assembly 2, a high-speed fan assembly 3 and a wind direction adjustment assembly 4; the air inlet assembly 2 and the high-speed fan assembly 3 are both installed at the upper end of the main body 1, the high-speed fan assembly 3 is connected with the air inlet assembly 2, the air inlet assembly 2 is connected to the baking cavity from the high-speed fan assembly 3, and the wind direction adjustment assembly 4 is installed at one end of the air inlet assembly 2 close to the baking cavity; after the user sets the baking program and starts the oven, the high-speed fan assembly 3 is started first to generate a strong airflow; the airflow generated by the high-speed fan is guided to the air inlet assembly 2, and the air inlet assembly 2 enables the airflow to flow smoothly to the baking cavity; at the same time, the inlet of the air inlet assembly 2 is tightly connected with the high-speed fan assembly 3 to ensure the sealing and continuity of the airflow; after the airflow enters the air inlet assembly 2, the direction is adjusted through the air adjustment pipe 41 in the wind direction adjustment assembly 4, so that The airflow that originally moved in a straight line is transformed into a spiral shape and enters the baking cavity. The design not only increases the flow path of the airflow, but also enables the airflow to be more widely distributed in the baking cavity, avoiding the problem of excessive temperature difference between the edge and the center of the baking cavity under the traditional direct current air intake mode; the spiral air intake mode makes the air circulation in the baking cavity more uniform, and the high-speed rotating air enters the baking cavity in a spiral state when it comes out of the air adjustment pipe 41, avoiding excessive concentration of high-speed flowing gas and causing uneven temperature distribution in the baking cavity, and the high-speed gas in spiral motion moves in a spiral in the baking cavity, and the radiation range is larger than the radiation area of ​​the straight-line flowing airflow, ensuring that all parts of the food can be evenly affected by heat, which not only improves the baking efficiency, but also allows the surface of the food to be evenly colored, avoiding local burnt or undercooked conditions, and ultimately presents a baking effect with attractive color and uniform taste.

[0028] The wind direction adjustment component 4 includes an air adjustment pipe 41, which is used to adjust the trajectory of the wind flow entering the baking cavity, and change the existing direct air inlet into a spiral air inlet, so that the temperature distribution in the baking cavity is uniform.

[0029] In one embodiment, the air regulating duct 41 is a retractable spiral structure; the unique design of the retractable spiral air regulating duct 41 enables the airflow to form a more complex and changeable flow path when passing through, which not only enhances the diffusion ability of the airflow, but also allows the airflow to stay in the baking cavity for a longer time, thereby improving the heat transfer efficiency and the uniformity of heating; since the air regulating duct 41 can be retracted and bent, the user can flexibly adjust the distribution of the airflow according to the size, shape and placement of the food, which greatly enhances the adaptability and flexibility of the oven, allowing it to easily cope with various baking tasks.

[0030] In one embodiment, the wind direction adjustment component 4 also includes a spiral frame 42 and a moving mechanism 43; the spiral frame 42 and the moving mechanism 43 are both installed on the main body 1, the spiral frame 42 is located at the bottom of the air inlet component 2, and the moving mechanism 43 is located at the spiral center of the spiral frame 42; the air regulating pipe 41 is sleeved on the spiral frame 42, and the moving mechanism 43 is connected to the spiral frame 42, and is used to drive the air regulating pipe 41 to perform spiral motion on the spiral frame 42; the movement of the screw motor 431 is converted into the spiral motion of the air regulating pipe 41, so that the air regulating pipe 41 moves along the spiral track of the spiral frame 42. Specifically, the spiral frame 42 is also a spiral structure, and the air regulating pipe 41 is installed on the spiral frame 42, so that the movement of the air regulating pipe 41 is restricted by the spiral frame 42, and the air regulating pipe 41 performs spiral motion along the track of the spiral frame 42; with the spiral motion of the air regulating pipe 41, the airflow forms a more complex and changeable flow path inside the air regulating pipe 41; when the airflow enters the baking cavity, a uniform spiral distribution has been formed. This distribution method helps to reduce the generation of temperature dead corners and hot spots and improve the uniformity of temperature in the baking cavity. At the same time, the spiral motion also enhances the diffusion capacity of the airflow, so that the heat can be transferred to various parts of the food more quickly; through the action of the moving mechanism 43, the movement trajectory and airflow distribution of the outlet end of the air regulating duct 41 can be flexibly controlled to adapt to foods of different sizes, shapes and baking requirements; the optimized airflow path and enhanced diffusion capacity enable the heat to be transferred to various parts of the food more quickly, thereby shortening the baking time and improving the baking efficiency.

[0031] In one embodiment, the moving mechanism 43 includes a screw motor 431, a moving block 432 and a flange connection block 433; the screw motor 431 is installed in the main body 1, the moving block 432 is threadedly connected to the screw motor 431, the flange connection block 433 is rotatably connected to the moving block 432, and the flange connection block 433 is also connected to the air regulating pipe 41; the moving mechanism 43 is intended to achieve precise adjustment and positioning of the position of the air regulating pipe 41, the screw motor 431 is installed in the main body 1 structure as a power source, and when the screw motor 431 receives a control signal, its internal The rotating motor in the lower part is decelerated by the reducer to drive the screw to rotate. The moving block 432 is designed with a thread structure matching the screw. When the screw rotates, due to the meshing action of the thread, the moving block 432 will move linearly along the axial direction of the screw, so that the moving distance of the moving block 432 can be accurately controlled by controlling the number of rotations of the screw motor 431. The flange connection block 433 is rotatably connected to the moving block 432 through a bearing or other rotating mechanism, ensuring that the flange connection block 433 can move while the moving block 432 moves. The air regulating pipe 41 can freely perform rotation adjustment within a certain range, that is, when the screw motor 431 drives the moving block 432 to move up and down, it can drive the telescopic air regulating pipe 41 to rotate, and the air regulating pipe 41 can perform the telescopic action while rotating, that is, the air regulating pipe 41 can perform spiral motion under the action of the screw motor 431 to adjust the outlet direction of the air regulating pipe 41, and the outlet end of the air regulating pipe 41 is set on the side instead of the bottom, wherein the flange connection block 433 plays a vital role, and the flange connection block 433 and the moving block 432 The movable block 432 is connected to the air regulating pipe 41, and the movement trend of the movable block 432 can be transmitted to the air regulating pipe 41. The movable block 432 can also rotate with the movable block 432 under the function of its own rotation. When rotating, the movable block 432 is consistent with the spiral movement of the air regulating pipe 41, and the coordination is ingenious, which increases the flexibility of the system, so that the air regulating pipe 41 can not only move in the horizontal or vertical direction, but also adjust the angle. By adjusting the position of the movable block 432 and the rotation angle of the flange connection block 433, the position of the air regulating pipe 41 can be accurately adjusted, thereby controlling the direction and intensity of the airflow.

[0032] In one embodiment, the air inlet assembly 2 includes an air duct 21, an air duct bracket 22 and an air inlet 23; the air duct 21 is installed on the main body 1 through the bracket, the air inlet 23 is set on the main body 1, and the air inlet 23 is connected from the air duct 21 to the baking cavity; the air duct 21 serves as the main channel for air circulation, and is firmly installed on the main body 1 structure through the air duct bracket 22. The design of the air duct bracket 22 needs to consider the requirements of load-bearing, stability and easy installation and maintenance to ensure that the air duct 21 can be firmly fixed in the designated position. The air inlet 23 is set on the main body 1, usually on one side or top of the baking cavity, and the specific position is determined according to the overall layout of the baking equipment and the aerodynamic principles; the air inlet 23 and the air duct 21 are sealed to ensure that external air can smoothly enter the air duct 21 without leakage. When the baking equipment starts working, external air is sucked into the air duct 21 through the air inlet 23. The air duct 21 may be designed with guide plates, dampers and other components to guide and control the air flow direction, ensuring that the air can enter the baking cavity evenly and efficiently; the air entering the baking cavity exchanges heat with the object to be baked, absorbs or releases heat, and then is discharged or recycled. In this way, a complete air circulation loop is formed to support the continuous baking process; through the reasonably designed air inlet 23 and air duct 21 structure, the efficient and orderly introduction of external air is achieved, providing a sufficient air source for the baking process, ensuring the stability of baking efficiency and quality; the design of the air inlet component 2 helps to achieve uniform distribution and flow of air in the baking cavity, thereby promoting uniform heat exchange between the object to be baked and the air, avoiding the occurrence of local overheating or overcooling, and improving the uniformity and consistency of baking.

[0033] In one embodiment, an air outlet is provided at one end of the main body 1 away from the air inlet 23; the air outlet is located at the end of the main body 1 away from the air inlet 23, and is usually designed at the other side or bottom of the baking cavity, so as to form a diagonal or relative layout with the air inlet 23, so as to maximize the air circulation effect. The main function of the air outlet is to discharge the air heated or cooled by the baking cavity to the outside of the baking device. When the baking device starts working, the external air is sucked into the air duct 21 through the air inlet 23 and then enters the baking cavity. In the baking cavity, after the air exchanges heat with the object to be baked, the temperature rises or drops, and the air carries the aroma and moisture of the object. Subsequently, the air is discharged through the air outlet; during the whole process, the air forms a closed-loop circulation system inside the baking device, realizing efficient heat transfer and uniform air distribution.

[0034] In one embodiment, the high-speed fan assembly includes a fan fixing base and a high-speed fan; the high-speed fan is fixed to the main body 1 through the fan fixing base, and the high-speed fan supplies air to the air duct 21; as a supporting structure of the high-speed fan, the fan fixing base is firmly installed inside or outside the main body 1 (depending on the design requirements), bears the weight of the high-speed fan, and ensures the stability and safety of the fan during operation. It is fixed to the main body 1 through the fan fixing base. The high-speed fan has a high rotation speed and wind output capacity, directly supplies air into the air duct 21, forms a strong airflow, and promotes the air to flow rapidly in the air duct 21. When the baking equipment starts to work, the high-speed fan starts first; driven by the motor, the fan blades rotate at a high speed to generate strong wind force, and the airflow generated by the high-speed fan is directly sent into the air duct 21. The airflow forms a positive pressure in the air duct 21, which promotes the air to flow toward the baking cavity; with the rapid flow of air, the heat in the baking cavity can be more efficiently transferred to the air, and discharged or recirculated through the air duct 21 and the air outlet. At the same time, fresh external air is continuously replenished into the air duct 21 through the air inlet 23, forming a continuous heat exchange and air circulation process to achieve the baking of food. The rapid flow of air promotes the heat exchange process between the object to be baked and the air, making the heat distribution more uniform, thereby improving the baking consistency and product quality.

[0035] In one embodiment, a heating assembly 5 is further included. The heating assembly 5 is used to provide heat to the baking cavity. The heating assembly 5 includes an upper heating tube 51 and a lower heating tube 52. The upper heating tube 51 is arranged at the upper end of the baking cavity, and the lower heating tube 52 is arranged at the lower end of the baking cavity. The upper heating tube 51 is arranged at the upper end of the baking cavity, usually arranged horizontally along the top of the baking cavity or adjusted appropriately according to the shape of the baking cavity. The upper heating tube 51 generates heat by electric heating or other means, and radiates or conducts heat to the inside of the baking cavity. The lower heating tube 52 is arranged at the lower end of the baking cavity, corresponding to the upper heating tube 51. The lower heating tube 52 also generates heat by electric heating or other means, and radiates or conducts heat upward. The combination of the upper and lower heating tubes 52 can form a three-dimensional heating effect, improve the uniformity and efficiency of baking, and before baking begins, the upper heating tube 51 and the lower heating tube 52 are started at the same time to preheat the baking cavity. During the preheating process, the heat generated by the heating tube is transferred to the air and the object to be baked in the baking cavity by radiation, conduction and convection, and the object to be baked is placed in the baking cavity. At this time, the upper heating tube 51 and the lower heating tube 52 continue to work to provide stable heat to the inside of the baking cavity. Since the heating tubes are respectively arranged at the upper and lower ends of the baking cavity, a bidirectional heating effect can be formed, so that the heat is more evenly distributed inside the baking cavity. At the same time, as the baking proceeds, heat exchange and air circulation will also occur between the air in the baking cavity and the object to be baked. The design of the lower dual heat source makes the heat more evenly distributed inside the baking cavity, reducing the uneven baking phenomenon caused by uneven heat distribution. This helps to improve the quality and consistency of the baked products. The heat pipe directly provides heat to the inside of the baking cavity, reducing the loss and delay in the heat transfer process. At the same time, the bidirectional heating method can heat up the object to be baked to the set temperature more quickly, thereby shortening the baking time and improving the baking efficiency.

[0036] In one embodiment, a control unit is also included, and the high-speed fan, the heating component 5 and the screw motor 431 are all electrically connected to the control unit; the control unit controls the screw motor 431 to drive the air regulating pipe 41 to move according to the heating data of the heating component 5; as the core control component of the baking equipment, the control unit is responsible for receiving and processing the data from each sensor (such as the temperature data of the heating component 5), and according to a preset program or algorithm, sends control instructions to the high-speed fan, the heating component 5 and the screw motor 431, and the control unit sends instructions to the screw motor 431 according to the heating data of the heating component 5 (possibly in combination with other sensor data) to drive the air regulating pipe 41 to move to the optimal position, which can maximize the air circulation efficiency, promote uniform heat distribution, and improve the baking effect. Through the centralized control of the control unit, the intelligent and automated baking process is realized, and the baking parameters are adjusted according to the real-time data to ensure the consistency of the baking effect and product quality. By accurately controlling the operation of the heating component 5 and the high-speed fan, and intelligently adjusting the position of the air regulating pipe 41, the baking equipment can provide a more stable and uniform baking environment, thereby improving the quality and taste of the baked products.
