Detailed Implementation Methods

[0031] To make the technical problems solved by this application, the technical solutions, and the beneficial effects clearer, this application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0032] Example 1: Please refer to Figures 1 to 12 This embodiment provides an airflow guiding mechanism for the cooking cavity of an electric oven, including an outer shell 1 and an inner shell 2. The interior of the inner shell 2 is the cooking cavity 3. The inner shell 2 includes a hot air side plate 5 located on one side and connected to a heat circulation assembly 4. The hot air side plate 5 has an air inlet mesh 6 in the middle that communicates with the heat circulation assembly 4. A plurality of air outlet holes 7 that communicate with the heat circulation assembly 4 are provided around the air inlet mesh 6. The air inlet mesh 6 and the plurality of air outlet holes 7 are used to realize the circulation of heating airflow. At least one airflow guiding device 8 is provided between the heat circulation assembly 4 and the hot air side plate 5. The airflow guiding device 8 is located at the opening of the air outlet hole 7 to constrain the heating airflow to flow in a slightly horizontal direction.

[0033] In the embodiment, the outer shell 1 of the electric oven is an external protective layer of integral structure, and the inner shell 2 is arranged inside the outer shell 1, and the inside of the inner shell 2 forms a cooking cavity 3 for accommodating food to be heated. One side of the inner shell 2 is provided with a hot air side plate 5, which is one of the structures constituting the inner shell 2, and the side end of the hot air side plate 5 is connected with a heat circulation assembly 4, which can include a heating element, a fan assembly and the like, for generating and driving the circulation of the heating air flow. The middle part of the hot air side plate 5 is provided with an air inlet mesh 6, which is in communication with the heat circulation assembly 4, for recycling the heating air flow in the cooking cavity 3 to the heat circulation assembly 4 for reheating. A plurality of air outlet holes 7 are arranged on the periphery of the air inlet mesh 6, which are also in communication with the heat circulation assembly 4, for introducing the heating air flow from the heat circulation assembly 4 into the cooking cavity 3. Through the cooperation of the air inlet mesh 6 and the air outlet hole 7, the circulation of the heating air flow is realized. A flow guide device 8 is arranged between the heat circulation assembly 4 and the hot air side plate 5. The flow guide device 8 is located at the orifice of the air outlet hole 7, and its function is to constrain the heating air flow to flow in a direction deviating from the horizontal direction, so as to optimize the air flow distribution. Due to the existence of the flow guide device 8, the air flow which would have been dispersed in various directions is constrained to flow in a direction deviating from the horizontal direction, thereby avoiding the problem of uneven heat distribution caused by the excessive dispersion of the heating air flow in the prior art. The traditional unguided air flow diffusion may cause the heating air flow to be concentrated in some areas, resulting in local overheating in the oven. However, through the precise control of the air flow direction by the flow guide device 8, the occurrence of local overheating is effectively avoided, the internal structure of the oven is protected, and the food is prevented from being burnt or undercooked. In addition, through the optimization of the air flow path, the heating air flow can more efficiently cover each area in the cooking cavity 3, reducing heat loss and improving overall thermal efficiency, thereby shortening the cooking time and reducing energy consumption.

[0034] Further, as a preferred embodiment of the present scheme but not limited, the heat circulation assembly 4 includes a wind guide cover 41 connected with the hot air side plate 5, the wind guide cover 41 is provided with a shaded pole motor 42 away from one side of the hot air side plate 5, the output shaft of the shaded pole motor 42 penetrates into the wind guide cover 41 and is connected with a fan blade 43, a plurality of air outlet holes 7 are arranged near the edge of the wind guide cover 41, and the flow guide device 8 is arranged at the edge of the wind guide cover 41 corresponding to the position of the air outlet hole 7.

[0035] In the present embodiment, the heat circulation assembly 4 comprises a wind guide 41 connected with the hot air side plate 5. The wind guide 41 is an important component of the heat circulation assembly 4, and its internal space is used to guide and distribute the heating air flow. The wind guide 41 is provided with a shaded pole motor 42 on the side away from the hot air side plate 5. The shaded pole motor 42 penetrates into the wind guide 41 through its output shaft, and is connected with a fan blade 43. The shaded pole motor 42 drives the fan blade 43 to rotate, thereby cooperating with the corresponding heating element in the oven to generate a high-temperature air flow and drive it to flow. A plurality of air outlets 7 are arranged on the hot air side plate 5 and are close to the circumferential edge of the wind guide 41. This arrangement enables the heating air flow to enter the cooking cavity 3 uniformly from the edge area of the wind guide 41, thereby optimizing the air flow distribution. The air flow guide device 8 is arranged at the edge of the wind guide 41 corresponding to the position of the air outlet 7, so as to ensure that the air flow guide device 8 can directly act on the heating air flow flowing out of the air outlet 7 and constrain it to flow in a direction deviating from the horizontal direction, thereby avoiding excessive dispersion of the air flow. Through the cooperation of the wind guide 41, the air outlet 7 and the air flow guide device 8, the heating air flow can be diffused in a more regular manner, covering each area in the cooking cavity 3, thereby significantly improving the uniformity of heating and ensuring consistent heating of food.

[0036] Further, as a preferred embodiment but not a limitation of the present scheme, at least one of the plurality of air outlets 7 is arranged on the upper portion of the hot air side plate 5, and the air flow guide device 8 is correspondingly arranged at the position of the air outlet 7.

[0037] A plurality of air outlets 7 are arranged on the hot air side plate 5, at least one of which is located on the upper portion of the hot air side plate 5. This arrangement enables the heating air flow to enter the cooking cavity 3 from different height areas of the hot air side plate 5, thereby optimizing the air flow distribution. On the other hand, the air flow guide device 8 is correspondingly arranged at the position of the air outlet 7 located on the upper portion of the hot air side plate 5. By arranging the air flow guide device 8 at the upper air outlet 7, the air flow that may have been diffused upward or too concentrated is effectively constrained to flow in a direction deviating from the horizontal direction, thereby avoiding the problem of local overheating in the upper area of the oven and improving the coverage range of the heating air flow.

[0038] It should be noted that, in the present embodiment, a plurality of air outlets 7 are arranged on the hot air side plate 5, for example, there are three air outlets 7, one of which is located on the upper portion of the hot air side plate 5, and the remaining two are located on the middle and lower portions of the hot air side plate 5. Whether the air flow guide device 8 is additionally arranged at these two positions can be determined according to the requirements. In some embodiments, in order to further stabilize the directional flow of the air flow in the upper portion of the cooking cavity 3, two or three air outlets 7 can also be arranged on the upper portion of the hot air side plate 5, and the air flow guide device 8 is arranged at each air outlet 7 located on the upper portion.

[0039] Further, as a preferred embodiment of the present scheme but not limited, the airflow guiding device 8 comprises a deflector 81, two ends of the deflector 81 are respectively connected with a first bending part 82, one end of the first bending part 82 is provided with a connecting part 83 connected with the air deflector 41, and the end of the first bending part 82 is close to the inner side wall of the air deflector 41, and a wind guiding transition cavity 84 is formed between the first bending part 82, the deflector 81 and the inner side wall of the air deflector 41, which is communicated with the air outlet hole 7.

[0040] In the embodiment, the airflow guiding device 8 comprises a deflector 81, two ends of the deflector 81 are respectively connected with a first bending part 82. One end of the first bending part 82 is provided with a connecting part 83 connected with the air deflector 41, and the connecting part 83 can be a common connecting structure such as a screw hole or a buckle. Correspondingly, the air deflector 41 is provided with a connecting and matching structure such as a mounting hole or a clamping groove corresponding to the connecting part 83. The end of the first bending part 82 is close to the inner side wall of the air deflector 41, which means that there is a small gap between them. A wind guiding transition cavity 84 is formed between the first bending part 82, the deflector 81 and the inner side wall of the air deflector 41, which is communicated with the air outlet hole 7, and is used to guide the heating airflow flowing out of the air outlet hole 7 to enter the wind guiding transition cavity 84 under the action of the fan blade 43, and to be constrained to flow in a horizontal direction by the action of the deflector 81. The existence of the wind guiding transition cavity 84 provides a buffer and stable space for the heating airflow, reduces the turbulence phenomenon of the airflow, thereby improving the stability of the airflow, and ensures that the airflow can be diffused in a more regular manner.

[0041] More specifically, the specific flow path of the heating airflow is as follows:

[0042] Firstly, the shaded pole motor 42 drives the fan blade 43 to rotate, and the heating airflow is introduced into the air deflector 41. The heating airflow is guided to the plurality of air outlet holes 7 close to the circumferential edge in the air deflector 41, including the air outlet holes 7 on the upper part of the hot air side plate 5. It should be noted that when the heating airflow flows out through the air outlet hole 7, it first enters the wind guiding transition cavity 84 formed by the first bending part 82, the deflector 81 and the inner side wall of the air deflector 41. In the wind guiding transition cavity 84, the heating airflow is constrained to flow in a horizontal direction by the action of the deflector 81. The guided heating airflow uniformly covers each area in the cooking cavity 3, and after completing heat transfer, it returns to the heat circulation assembly 4 through the air inlet mesh 6. After being heated again, the airflow in the heat circulation assembly 4 repeats the above-mentioned circulation process.

[0043] Further, as a preferred embodiment but not a limitation of the present solution, the guide vane 81 is an arc-shaped structure with an opening away from the inner side wall of the air deflector 41. The arc-shaped structure design reduces the resistance of the airflow during the guiding process, avoiding the turbulence phenomenon on the surface of the guide vane 81, thereby improving the stability and smoothness of the airflow.

[0044] Further, as a preferred embodiment but not a limitation of the present solution, the guide vane 81 is bent towards the inner side wall of the air deflector 41 at one end close to the hot air side plate 5. The bending design of the guide vane 81 at one end close to the hot air side plate 5 can better guide the heating airflow into the air deflector transition chamber 84, avoiding direct dispersion or loss of airflow, thereby improving the concentration and stability of the airflow, while ensuring that more heat can be efficiently utilized, thereby improving the overall thermal efficiency.

[0045] Further, as a preferred embodiment but not a limitation of the present solution, the guide vane 81 is connected with a second bending part 85 at one end close to the inner side wall of the air deflector 41, and the second bending part 85 is provided with a connecting hole 86 for fixing to the inner wall of the air deflector 41, for firmly fixing the guide vane 81 to the inner wall of the air deflector 41 by bolts, rivets or other fixing methods.

[0046] In the present embodiment, the provision of the second bending part 85 and the connecting hole 86 enables the guide vane 81 to be firmly fixed to the inner wall of the air deflector 41, avoiding loosening or deformation caused by high temperature or airflow impact, thereby improving the structural stability of the entire airflow guiding device 8.

[0047] Further, as a preferred embodiment but not a limitation of the present solution, a pressure relief groove 87 is provided between the first bending part 82 and the second bending part 85, for releasing excess pressure when the heating airflow passes through the air deflector transition chamber 84, avoiding turbulence or airflow instability caused by excessive airflow pressure, thereby improving the stability and uniformity of the airflow. In addition, the release of excess pressure through the pressure relief groove 87 can also reduce the noise generated by the high-speed airflow in the air deflector transition chamber 84.

[0048] Further, as a preferred embodiment but not a limitation of the present solution, the air deflector 41 is circular, and the circular air deflector 41 cooperates with the airflow guiding device 8 to optimize the path of the heating airflow. The circular structure of the air deflector 41 provides a symmetrical flow environment for the heating airflow, enabling the airflow to flow more smoothly out of the air outlet 7 and be constrained to flow in a horizontal direction by the airflow guiding device 8.

[0049] Embodiment 2: Please refer to Figures 1 to 2 The present embodiment provides an electric oven, which comprises an airflow guiding mechanism for the cooking chamber of an electric oven as described in Embodiment 1.

[0050] Specifically, the electric oven comprises an outer shell 1 and an inner shell 2, and the inside of the inner shell 2 is a cooking cavity 3. A heat insulation space is formed between the outer shell 1 and the inner shell 2 for reducing heat loss. The cooking cavity 3 is provided with conventional components such as a grill and a baking tray for placing food to be cooked.

[0051] In addition, since the embodiment includes all the technical solutions of Embodiment 1, the heating air flow can more evenly cover each area in the cooking cavity 3 during actual cooking, avoiding the problem of local overheating or uneven heating of the electric oven in the prior art due to excessive dispersion of the air flow. The optimized air flow path reduces heat loss, improves overall thermal efficiency, thereby shortens the cooking time and reduces energy consumption, and the uniform heating effect and efficient heat circulation also improve the taste and appearance of the food, improving the user experience.

[0052] The working principle of the utility model:

[0053] The embodiment provides an air flow guiding mechanism of an electric oven cooking cavity and an application thereof, which realizes uniform heat distribution, improves thermal efficiency and avoids local overheating by optimizing the flow path and direction of the heating air flow. The core lies in that the air inlet mesh holes on the hot air side plate and the plurality of air outlet holes cooperate with the heat circulation assembly to form air flow circulation, and the air flow guiding device is arranged at the air outlet hole to constrain the heating air flow to flow in a horizontal direction, preventing uneven heat distribution caused by air flow dispersion. The air flow guiding device comprises an arc-shaped flow guide piece, a bending part and a pressure relief groove, which buffers and stabilizes the air flow through the air guide transition cavity, reduces turbulence and noise, and ensures that the air flow covers each area of the cooking cavity. The multi-layer air outlet hole design (such as the upper part and the middle and lower parts) further optimizes the air flow distribution and avoids local overheating. The circular air guide cover cooperates with the air flow guiding device to provide a symmetrical flow environment for the air flow, enhancing uniformity. The electric oven based on the air flow guiding mechanism significantly improves the heating efficiency, shortens the cooking time, reduces the energy consumption, and improves the uniformity of the food heating and the taste, optimizing the user experience. The overall design solves the problem of local overheating or uneven heating of the traditional electric oven caused by air flow dispersion by precisely controlling the air flow path, and has high efficiency and practicality, meeting the energy saving and environmental protection requirements.

[0054] The above is an embodiment provided in combination with specific content, and it is not intended to limit the specific implementation of the application to these descriptions. Any approximation to the method structure of the application or technical deduction or replacement made on the basis of the concept of the application should be considered as the protection scope of the application.
