Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, and in particular to an air fryer. Background Technology

[0002] Existing air fryers mainly consist of a shell assembly, a basket assembly, a hot air assembly, and a control assembly. The hot air assembly includes a heating element, a motor, and a centrifugal fan. The centrifugal fan is fixed to the motor and can rotate synchronously with the motor shaft. The shell assembly has an open inner cavity. The basket assembly is detachably installed inside the inner cavity of the shell assembly, sealing the opening and creating a relatively sealed inner cavity. A safety interlock switch connects the basket assembly and the shell assembly; however, the product will not operate if the basket assembly is not properly installed. The heating element is fixed to the upper part of the inner cavity of the shell assembly, with the motor and fan located above the heating element.

[0003] When frying food, first place the prepared ingredients in the frying basket, then push the basket into the inner cavity of the main body and ensure it is in place. Start the machine via the control components, and the heating element and motor will begin to work. The motor drives the centrifugal fan to rotate at high speed, creating a high-speed airflow inside the frying basket cavity. At the same time, the heat generated by the heating element is carried into the frying basket, allowing the food inside the basket to fully contact the high-temperature airflow and be heated until cooked.

[0004] However, existing air fryers generally have their airflow outlets located at the top to guide airflow through the frying basket. While this design ensures even heating of food, it also makes the heating elements and fan prone to accumulating grease, affecting not only the cleanliness of the equipment but also its performance and lifespan.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings.

[0032] Please see Figures 1 to 7 This utility model discloses an air fryer, including a main housing 1, a food container 2, and a hot air assembly 3; the main housing 1 has a heating chamber 11 and a cooking chamber 12, the heating chamber 11 being located above the cooking chamber 12, and a first exhaust vent 13 communicating with the outside being provided at the lower part of the cooking chamber 12; the food container 2 is disposed in the cooking chamber 12, and the food container 2 is used to hold the food to be fried, and a vertically extending ventilation gap 4 is formed between the side wall of the food container 2 and the side wall of the cooking chamber 12; the hot air assembly 3 is disposed in the heating chamber 11. The hot air assembly 3 has an air outlet 331 located above the food container 2. A laterally extending ventilation gap 5 is formed between the air outlet 331 and the food container 2. The air outlet 331, the ventilation gap 5, and the cavity of the food container 2 are sequentially connected. A ventilation gap 4 connects the first exhaust vent 13 and the ventilation gap 5. Thus, the ventilation gap 4 not only serves as part of the hot air circulation but also connects the first exhaust vent 13 and the ventilation gap 5, ensuring that airflow can smoothly exit from the lower part of the cooking cavity 12. Specifically, after the hot air flows out from the air outlet 331, it first passes through the ventilation gap 5 and the cavity of the food container 2 from top to bottom to cook the food. Then, the hot air exits the cooking cavity 12 from the cavity of the food container 2 through the ventilation gap 5, the ventilation gap 4, and the first exhaust vent 13.

[0033] The air fryer provided in this embodiment optimizes the airflow path, guiding the airflow to the ventilation gap 4 and then out from the first exhaust port 13 at the bottom of the cooking chamber 12, thereby effectively avoiding the problem of the hot air assembly 3 being contaminated with oil. This design not only improves the cleanliness and service life of the equipment, but also ensures the frying effect of the food. At the same time, the air fryer of the present invention has a simple structure, is easy to manufacture and maintain, and has broad application prospects.

[0034] like Figure 2 As shown, specifically in this embodiment, the main housing 1 includes a detachably connected upper housing 18 and a lower housing 19, with a heating cavity 11 disposed on the upper housing 18 and a cooking cavity 12 disposed on the lower housing 19.

[0035] like Figure 2 and Figure 3 As shown, specifically, in this embodiment, the hot air assembly 3 includes a heating element 31, a fan 32, and an air outlet sidewall 33. The heating element 31, fan 32, and air outlet sidewall 33 are all disposed within the heating chamber 11, and the air outlet 331 is disposed on the air outlet sidewall 33. Thus, on the one hand, integrating the heating element 31, fan 32, and air outlet sidewall 33 within the heating chamber 11 not only makes the entire air fryer structure more compact but also greatly improves the utilization efficiency of the internal space. This design not only reduces the overall size of the device but also allows the various parts of the hot air assembly 3 to work more closely together, improving the generation and transmission efficiency of hot air. On the other hand, by providing the air outlet 331 on the air outlet sidewall 33, the hot air assembly 3 can more precisely control the flow direction of the hot air. This design ensures that the hot air can efficiently enter the cooking chamber 12 along a predetermined path, uniformly and fully heating the food, while also reducing hot air waste and unnecessary energy loss.

[0036] like Figure 3 and Figure 7 As shown, preferably, in this embodiment, the side of the air outlet sidewall 33 facing the food container 2 is flat. This design ensures, on the one hand, that the flat air outlet sidewall 33 ensures that the hot air flowing out of the air outlet 331 is more uniform and stable. This design avoids airflow turbulence caused by unevenness in the air outlet surface, allowing the hot air to penetrate the food container 2 more smoothly and heat the food evenly. On the other hand, the flat air outlet sidewall 33 is easier to clean and less prone to accumulating dirt. This design helps reduce the difficulty and time required for users to clean the equipment, thereby extending the equipment's lifespan.

[0037] like Figure 3 and Figure 7As shown, more preferably, in this embodiment, the air outlets 331 are evenly distributed on the air outlet sidewall 33. This even distribution of the air outlets 331 on the air outlet sidewall 33 ensures a more uniform distribution of hot air within the cooking cavity 12. This design helps reduce temperature gradients during cooking, allowing the food to be heated more evenly and stably, thereby improving cooking quality and taste. Specifically, in this embodiment, the air outlets 331 are arranged in a ring shape on the air outlet sidewall 33. This ring-shaped air outlet design helps achieve more efficient heat energy conversion and utilization. By reducing unnecessary energy consumption, this design can lower the operating costs of the equipment and meets the modern family's pursuit of energy conservation and environmental protection.

[0038] like Figure 3 and Figure 5 As shown, preferably, in this embodiment, the first exhaust vent 13 has multiple exhaust holes 131 arranged in multiple rows and columns. This increases the exhaust area, allowing hot air to exit the cooking chamber 12 more quickly, reducing the temperature and humidity within the cooking chamber 12. This facilitates rapid frying and oil removal of food, while also reducing the risk of oil contamination on the heating element 31 and the fan 32. Furthermore, by increasing the number and distribution of exhaust holes 131, the air fryer's heat dissipation performance is significantly improved, which not only helps extend the equipment's lifespan but also enhances its stability and safety. Finally, the optimized airflow path and exhaust design result in lower noise and energy consumption during use, while also improving the frying effect, thereby enhancing the user's cooking experience and satisfaction.

[0039] like Figure 3 and Figure 5 As shown, preferably, in this embodiment, the cooking cavity 12 has a vertical sidewall 15 opposite to the food container 2, and the first exhaust vent 13 is disposed on the vertical sidewall 15. Thus, since the first exhaust vent 13 is located on the vertical sidewall 15, oil stains and food residue generated during cooking are less likely to adhere around the exhaust vent. This design not only facilitates cleaning of the cooking cavity 12 by the user but also helps extend the service life of the equipment.

[0040] like Figure 3 , Figure 5 and Figure 6As shown, more preferably, in this embodiment, the main housing 1 has a guide sidewall 16 disposed opposite to the vertical sidewall 15. Specifically, the guide sidewall 16 is located in the lower housing 19, and a second exhaust port 14 is formed between the lower part of the guide sidewall 16 and the lower part of the vertical sidewall 15. The second exhaust port 14 is located below the first exhaust port 13 and is connected to the first exhaust port 13. Thus, on the one hand, the second exhaust vent 14 is connected to the first exhaust vent 13, forming a complete exhaust path. This design not only helps reduce air pressure fluctuations within the cooking cavity 12, but also makes the exhaust process more efficient and stable. Furthermore, since the second exhaust vent 14 is located at the bottom, it can better utilize gravity to help hot air escape smoothly from the cooking cavity 12. On the other hand, by optimizing the exhaust path and enhancing airflow, the temperature distribution within the cooking cavity 12 is more uniform. This helps ensure even heating of food and improves cooking quality. Simultaneously, because hot air can escape more smoothly from the cooking cavity 12, it reduces the accumulation of fumes and odors, enhancing the taste and flavor of the food. Moreover, the placement of the second exhaust vent 14 makes cleaning the cooking cavity 12 easier. Since hot air is mainly exhausted through the first and second exhaust vents 13 and 14, these areas are relatively prone to accumulating grease and food residue. However, because the second exhaust vent 14 is located at the bottom and is relatively spacious, users can more easily perform cleaning and maintenance.

[0041] like Figure 3 and Figure 4 As shown, preferably in this embodiment, the ventilation gap 4 is partially arranged around the food container 2. In this way, after passing through the food container 2, the hot air can flow more smoothly to the first exhaust vent 13 with the help of the ventilation gap 4, forming an effective air circulation. This design helps to accelerate the flow of hot air, improve cooking efficiency, and reduce the accumulation of fumes and odors.

[0042] It should be noted that in some other embodiments, the ventilation gap 4 may also be set to completely surround the food container 2.

[0043] like Figure 1 , Figure 2 and Figure 5As shown, specifically, in this embodiment, the air fryer also includes a handle panel 6. The main body shell 1 is provided with an opening 17, through which the food container 2 can be inserted into the main body shell 1. The handle panel 6 is detachably connected to the opening 17, and when the handle panel 6 is connected to the opening 17, it can form a seal on the opening 17. Thus, on the one hand, the handle panel 6 is detachably connected to the opening 17 of the main body shell 1, and when the handle panel 6 is connected to the opening 17, it can effectively seal the opening 17. This sealing design can prevent hot air or fumes from leaking out of the opening 17 during cooking, thereby avoiding the risk of scalding the user or polluting the kitchen environment. At the same time, the sealing design also helps to maintain stable temperature and pressure inside the cooking chamber 12, improving cooking efficiency and the taste of the food. On the other hand, the design of the handle panel 6 allows the user to easily open and close the cooking chamber 12. When it is necessary to insert or remove the food container 2, the user only needs to simply detach the handle panel 6. This design not only simplifies the operation process but also improves user convenience. Furthermore, the process of disassembling and installing the handle panel 6 is generally... Relatively simple, requiring no additional tools or complicated steps; on the other hand, the detachable connection design between the handle panel 6 and the main body shell 1 helps extend the service life of the device. Since the handle panel 6 is detachable, users can more easily clean and maintain it. At the same time, this design also makes it easier to replace the handle panel 6 when it is damaged or worn, thus avoiding the scrapping of the entire device; furthermore, the design of the handle panel 6 is not only practical, but also enhances the overall appearance of the air fryer. By choosing appropriate materials, colors and shapes, the handle panel 6 can form a coordinated appearance style with the main body shell 1, thereby enhancing the overall aesthetics of the device. In addition, the design of the handle panel 6 can also take ergonomic factors into account, making it more in line with the user's usage habits and needs.

[0044] like Figure 1 , Figure 2 and Figure 5As shown, preferably, in this embodiment, the sidewall of the opening 17 is provided with a guide groove 171, and the sidewall of the handle panel 6 is provided with a guide block 61, which is detachably connected to the guide groove 171. Thus, on the one hand, the design of the guide groove 171 and the guide block 61 makes the installation and removal of the handle panel 6 simpler and more intuitive. The user only needs to align the guide block 61 with the guide groove 171 and gently push it in or pull it out to complete the connection or separation of the handle panel 6. This design not only reduces the difficulty of installation and removal but also improves the user's operating efficiency. On the other hand, the cooperative design of the guide groove 171 and the guide block 61 ensures a more stable connection between the handle panel 6 and the main housing 1. Since the guide block 61 is confined within the guide groove 171, the handle panel 6 is less likely to shake or fall off during connection. This stability not only helps maintain the sealing of the cooking cavity 12 but also prevents safety risks caused by the loosening of the handle panel 6 during cooking.

[0045] like Figure 2 , Figure 3 and Figure 5 As shown, more specifically, in this embodiment, the opening 17 is located on the side of the main housing 1 away from the first exhaust vent 13. Thus, on the one hand, placing the opening 17 away from the first exhaust vent 13 ensures that hot air does not escape directly from the opening 17 during cooking, but instead flows along a designed path within the cooking cavity 12. This design helps enhance the utilization rate of hot air, improve cooking efficiency, and ensure that the food is heated evenly. On the other hand, the design of the opening 17 being away from the first exhaust vent 13 helps reduce heat loss during cooking. Since hot air does not escape directly from the opening 17, the temperature within the cooking cavity 12 can remain stable, thereby reducing the problem of prolonged cooking time or deterioration of food texture due to heat loss.

[0046] In summary, the air fryer disclosed in this utility model can bring at least the following beneficial technical effects:

[0047] 1) By optimizing the airflow path, the airflow is guided to the ventilation gap 4 and then flows out from the first exhaust port 13 at the bottom of the cooking cavity 12, thereby effectively avoiding the problem of the hot air assembly 3 being contaminated with oil.

[0048] 2) The flat air outlet sidewall 33 can ensure that the hot air flows out of the air outlet 331 more evenly and stably. This design avoids airflow turbulence caused by uneven air outlet surface, so that the hot air can penetrate the food container 2 more smoothly and heat the food evenly.

[0049] 3) The flat air outlet sidewall 33 is easier to clean and less prone to accumulating dirt. This design helps reduce the difficulty and time for users to clean the equipment, thereby extending the service life of the equipment.

[0050] 4) By increasing the number and distribution of exhaust vents 131, the heat dissipation performance of the air fryer has been significantly improved, which not only helps to extend the service life of the equipment, but also improves the stability and safety of the equipment.

[0051] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
