Description

Technical Field

[0001] This utility model relates to the field of ovens, and in particular to an air fryer oven based on heat flow optimization. Background Technology

[0002] Existing air fryers typically consist of a cabinet, cooking cavity, fan, heating element, and door, using hot air circulation to heat food. However, these products have significant drawbacks in use: First, the hot air circulation within the cooking cavity can create dead zones, leading to uneven heating of food and requiring manual turning mid-cooking, impacting the user experience; second, grease dripping during cooking is splashed by the high-speed hot air and adheres to the heating element and inner cavity walls, making cleaning difficult and posing safety hazards, and the repeated carbonization of grease also produces harmful fumes; although some products have an oil collection tray, these are mostly located at the bottom of the cavity and are horizontally placed, resulting in low oil collection efficiency. Grease cannot be quickly drained and remains, participating in secondary heating, failing to fundamentally solve the cleaning and fume problems. Utility Model Content

[0003] The purpose of this invention is to provide an air fryer oven based on heat flow optimization to solve the above-mentioned problems.

[0004] According to one aspect of the present invention, an air fryer oven based on heat flow optimization is provided, including a housing, a cooking cavity disposed within the housing, a fan located on one side of the cooking cavity, a heating tube located at the top of the cooking cavity, and a door. An oil collection tray is disposed at the bottom of the housing, and a flow-guiding oil collection tray is disposed at the bottom of the cooking cavity. The bottom surface of the flow-guiding oil collection tray is provided with a slope that slopes from all sides towards the center, and an oil guide hole for guiding oil into the oil collection tray is provided at the lowest point of the slope. The oil guide hole is disposed above the oil collection tray.

[0005] In some embodiments, the inclined angle of the flow-guiding oil-collecting disc is 5°-15°.

[0006] In some embodiments, the bottom of the housing is provided with support feet, and the inner side of the support feet is provided with through grooves. The oil collection tray passes through the through grooves on both sides. Limiting blocks are provided on both sides of the front part of the oil collection tray to limit the insertion depth of the oil collection tray.

[0007] In some embodiments, the inclined surface of the flow-guiding oil-collecting disk is provided with a number of turbulence protrusions for disturbing the airflow and creating turbulence.

[0008] In some embodiments, the turbulence protrusion is one of hemispherical, wavy, or rhomboid shapes.

[0009] In some embodiments, the oil-collecting guide plate is integrally stamped from a metal material.

[0010] Compared with the prior art, the beneficial effects of this application are as follows:

[0011] This utility model, through the combined design of a flow-guiding oil-collecting tray and a bottom oil-collecting tray, brings significant benefits: First, the inclined surface of the flow-guiding oil-collecting tray and the oil-guiding hole at its lowest point can quickly guide the dripping oil into the independent oil-collecting tray below, effectively preventing oil from splashing, stagnating, and being reheated in the cooking cavity, fundamentally reducing cleaning difficulty, eliminating the risk of oil fumes, and improving safety; Second, the inclined flow-guiding oil-collecting tray and the turbulence protrusions on it can effectively disrupt the reflected hot air, forming a more uniform turbulence in the cavity, greatly improving the uniformity of heat distribution, making the food brown more evenly, achieving uniform heating without flipping, and improving cooking effect and user experience; Third, the oil-collecting tray adopts a pull-out design and is positioned by a limiting block, making it extremely convenient to remove, place, and clean. The overall structure is simple, reliable, and highly practical. Attached Figure Description

[0017] 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.

[0018] refer to Figures 1 to 5This application provides an air fryer oven based on heat flow optimization, including a housing 1, a cooking cavity 2 disposed within the housing 1, a fan 3 located on one side of the cooking cavity 2, a heating tube 4 located at the top of the cooking cavity 2, and a door 5. An oil collection tray 6 is disposed at the bottom of the housing 1, and an oil guiding tray 7 is disposed at the bottom of the cooking cavity 2. The bottom surface of the oil guiding tray 7 is provided with a slope that slopes from all sides towards the center, and an oil guide hole 8 for guiding oil into the oil collection tray 6 is provided at the lowest point of the slope. The oil guide hole 8 is disposed above the oil collection tray 6.

[0019] In some embodiments, the inclined angle of the slope of the oil-collecting plate 7 is 5°-15°.

[0020] A tilt angle of 5°-15° is the optimal solution after careful consideration. It ensures that the oil flows to the oil guide hole 8 at the best speed under the action of gravity. If the angle is too small, the flow will be obstructed. If the angle is too large, it will occupy too much vertical space in the cavity and may cause the food to slide. This angle achieves the best balance between efficient flow and maintaining sufficient hot air circulation space, ensuring that the performance of the air fryer is not affected.

[0021] In some embodiments, the bottom of the housing 1 is provided with a support foot 9, and the inner side of the support foot 9 is provided with a through groove 10. The oil collection tray 6 is inserted between the through grooves 10 on both sides. Limiting blocks 11 are provided on both sides of the front part of the oil collection tray 6. The limiting blocks 11 are used to limit the insertion depth of the oil collection tray 6.

[0022] The design of inserting the slot 10 and positioning the limiting block makes it extremely simple and quick to pull out and clean the oil collection tray 6, greatly improving the user experience. The limiting block structure ensures that the oil collection tray 6 can accurately stop directly below the oil guide hole 8, perfectly catching the dripping grease and avoiding grease leakage caused by improper installation, making the design more reliable.

[0023] In some embodiments, the inclined surface of the flow-guiding oil-collecting disk 7 is provided with a number of turbulence protrusions 12 for disturbing the airflow and forming turbulence.

[0024] These turbulence protrusions 12 can effectively disrupt the laminar hot airflow at the bottom of the pot, making it form a more uniform turbulence, thereby penetrating the gaps in the food, reducing heating dead spots and edge burning, and achieving uniform heating without flipping the food; this structure, based on efficient airflow guidance, adds the function of optimizing the heat field, realizing the multi-functionality of a single component, and the structural design is ingenious.

[0025] In some embodiments, the turbulence protrusion 12 is one of a hemispherical, wavy, or rhomboid shape.

[0026] Specific shapes such as hemispherical, wavy, or rhomboid can produce different reflection and disturbance effects on the airflow, thereby most effectively generating uniform turbulence and further refining the heating uniformity; the turbulence protrusions 12 are smooth or without sharp corners, making it less likely to leave stains and also easy to wipe and clean.

[0027] In some embodiments, the oil-collecting and diverting disc 7 is integrally stamped from a metal material.

[0028] The one-piece stamping process ensures the structural strength of the parts, prevents oil leakage due to the absence of splicing gaps, and is suitable for mass production, with low cost and high reliability.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
