Description

Technical Field

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

[0002] With the improvement of people's living standards and the enhancement of health awareness, air fryers, as a new type of kitchen appliance, have been favored by consumers because they can use hot air circulation to achieve the frying effect of food and reduce the amount of oil used in the cooking process. In the use of air fryers, the frying basket inside the cooking chamber is the key component that holds the food, while the frying plate inside the basket provides the space for placing the food. The ventilation holes on the frying plate help hot air pass through the food evenly, achieving efficient cooking.

[0003] In existing air fryer designs, to prevent food residue or grease from falling onto the vent and then into the cooking chamber, increasing cleaning difficulty, the vent is usually located on the side wall at the bottom of the frying basket. While this design reduces the amount of food residue and grease entering the cooking chamber to some extent, it introduces new problems. A side-wall vent may limit the basket's capacity, making it difficult to hold a larger amount of food within a limited space, thus reducing the air fryer's practicality.

[0004] To address the issues arising from the sidewall placement of the air vents, some manufacturers have attempted to position them on the bottom wall of the frying basket. While this improvement enhances cooking performance and basket capacity, it introduces new cleaning challenges. When food cooks on the frying plate, food scraps and grease inevitably fall through the ventilation holes. Because the vents are located on the bottom wall, these scraps and grease easily fall directly into the cooking cavity, contaminating its interior and adhering to its walls. This accumulation severely impacts the air fryer's heating efficiency and lifespan, while also significantly hindering cleaning. Users must dedicate considerable time and effort to deep cleaning, sometimes even requiring disassembly of parts to thoroughly remove grime, undoubtedly diminishing the user experience.

[0005] Therefore, how to effectively prevent food residue and grease from falling from the air vent into the cooking chamber while ensuring the air fryer basket capacity has become a pressing technical problem to be solved in the current air fryer industry. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an air fryer that can both ensure the capacity of the frying basket and effectively prevent food residue and grease from falling from the air outlet into the cooking cavity, and is easy to clean.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] An easy-to-clean air fryer has a cooking chamber and a detachable frying basket disposed in the cooking chamber. The bottom wall of the frying basket is provided with an air vent. A frying plate is detachably suspended inside the frying basket. The frying plate has a food placement area with ventilation holes. The bottom wall of the frying basket protrudes upward to form a boss structure. The boss structure is configured such that its projection in the vertical direction does not intersect with the food placement area.

[0009] The air outlet is arranged on the boss structure to prevent food residue or grease falling from the ventilation hole from falling to the air outlet and into the cooking cavity.

[0010] Furthermore, the boss structure is arranged in a ring on the bottom wall and is located outside the food placement area. The middle part of the boss structure forms a first oil accumulation area for collecting grease dripping from the ventilation hole.

[0011] Furthermore, there is a gap between the boss structure and the side wall of the frying basket, which forms a second oil accumulation area configured to collect grease dripping from the edge of the frying plate.

[0012] Furthermore, the ventilation holes are arranged in a radial array in the food placement area of ​​the frying plate, and the frying plate is also provided with a handle hole in the middle for easy handling.

[0013] Furthermore, the bottom of the frying plate is provided with a support member so that the frying plate is suspended in the frying basket.

[0014] Furthermore, the support member is configured as a spring sheet extending downward from the edge of the frying plate. When the frying plate is installed into the frying basket, the spring sheet has a supporting force toward the side wall of the frying basket to facilitate the fixing of the frying plate.

[0015] Furthermore, the cooking cavity is provided with raised ribs, which are configured to support the bottom of the frying basket so that the bottom of the frying basket is suspended in the cooking cavity to facilitate the circulation of airflow.

[0016] Furthermore, a circulating air vent is provided on the side wall of the cooking cavity, and the air fryer is provided with a circulating cavity communicating with the circulating air vent, and a centrifugal fan is provided in the circulating cavity to generate circulating air.

[0017] Furthermore, the top of the cooking cavity has a hot air channel, and the top of the circulation cavity is provided with a vent that communicates with the hot air channel. The hot air channel has hot air holes that face downward toward the cooking cavity.

[0018] Furthermore, a heating tube is provided in the hot air channel and / or the circulation chamber.

[0019] Due to the adoption of the above technical solutions, this utility model has the following beneficial effects:

[0020] 1. This invention, by incorporating a raised structure on the bottom wall of the frying basket and arranging the air outlet on this raised structure, significantly reduces the probability of food residue or grease falling from the frying plate ventilation holes onto the air outlet and directly into the cooking cavity. This solves the cleaning problem caused by food residue and grease falling into the cooking cavity of existing air fryers. The raised structure effectively blocks falling residue and grease inside the frying basket, requiring only periodic cleaning of the basket, greatly reducing the frequency and difficulty of cleaning the cooking cavity, saving users time and effort, and improving the user experience.

[0021] 2. The first oil accumulation area is formed in the middle of the boss structure of this utility model, and the gap between it and the side wall of the frying basket forms a second oil accumulation area. This dual oil accumulation area design can collect the oil dripping from the ventilation hole and the oil dripping from the edge of the frying plate, respectively. This prevents some of the oil falling from the edge of the frying plate from flowing to the air outlet. Attached Figure Description

[0034] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the features in the following embodiments can be combined with each other.

[0035] This utility model provides an easy-to-clean air fryer, which has a cooking chamber and a detachable frying basket disposed in the cooking chamber. The bottom wall of the frying basket is provided with an air outlet. A frying plate is detachably suspended in the frying basket. The frying plate has a food placement area with ventilation holes. The bottom wall of the frying basket protrudes upward to form a boss structure. The boss structure is configured such that its projection in the vertical direction does not intersect with the food placement area. The air outlet is arranged on the boss structure to prevent food residue or grease falling from the ventilation holes from falling to the air outlet and into the cooking chamber.

[0036] See Figures 1 to 3 The air fryer 100 of this embodiment includes a cooking chamber 101 and a detachable frying basket 110 disposed within the cooking chamber 101. A frying plate 120 is detachably suspended within the frying basket 110, and the frying plate 120 has a food placement area 121 with ventilation holes 122 for placing food to be cooked. The bottom wall of the frying basket 110 has an air outlet 111 for exhausting hot air and realizing hot air circulation.

[0037] In this embodiment, the bottom wall of the frying basket 110 has a boss structure 112, which is configured such that its projection in the vertical direction does not intersect with the food placement area 121. The air vent 111 is arranged on the boss structure 112. This design can effectively reduce the probability that food residue or grease falling from the ventilation hole 122 will fall onto the air vent 111 and directly into the cooking cavity 101.

[0038] In some embodiments, the boss structure is arranged in a ring on the bottom wall and located outside the food placement area, with the middle part of the boss structure forming a first oil accumulation area for collecting grease dripping from the ventilation hole.

[0039] See Figure 2 and Figure 3In this embodiment, a first oil accumulation area 113 is formed in the middle of the boss structure 112 to collect grease dripping from the ventilation hole 122. It is understood that the first oil accumulation area 113 is located directly below the object placement area. Due to the presence of the boss structure 112, the grease collected in the first oil accumulation area 113 will not flow to the air outlet 111.

[0040] In one specific embodiment, there is a gap between the boss structure and the side wall of the frying basket, which forms a second oil collection area configured to collect grease dripping from the edge of the frying plate.

[0041] In this embodiment, there is a gap between the boss structure 112 and the side wall of the frying basket 110, which forms a second oil collection area 114 for collecting grease dripping from the edge of the frying plate 120. During the use of the air fryer, especially when cooking foods with a lot of oil, the grease cooked at high temperature may splatter onto the side wall of the frying basket and flow down to the bottom wall. By setting the second oil collection area 114, the grease left on the side wall can be effectively collected, preventing it from flowing directly to the air outlet 111.

[0042] In summary, this dual-oil-collecting zone design effectively concentrates and collects grease and residue, preventing them from entering the cooking cavity 101, thus significantly reducing the frequency and difficulty of cleaning the cooking cavity. In practical use, users can keep the frying basket 110 clean by periodically cleaning the grease in the first oil-collecting zone 113 and the second oil-collecting zone 114. This dual-oil-collecting zone design not only solves the cleaning problem but also prevents excessive accumulation of grease and residue in the frying basket 110, thereby extending the lifespan of the air fryer and reducing the risk of equipment damage due to untimely cleaning.

[0043] In some embodiments, ventilation holes are arranged in a radial array in the food placement area of ​​the frying plate, and a handle hole is provided in the middle of the frying plate for easy handling.

[0044] See Figure 5 In this embodiment, the ventilation holes 122 of the frying plate 120 are arranged in a radial array. This distribution ensures uniform circulation of hot air in the food placement area 121, making the food heat more evenly during cooking and avoiding the problems of local overheating or uneven cooking that may occur in traditional designs. At the same time, the frying plate 120 is provided with a handle hole 123 in the middle for easy removal. Users can easily take the frying plate 120 out of or into the frying basket 110 through the handle hole 123, which facilitates food placement and cleaning.

[0045] In some embodiments, the bottom of the frying plate is provided with a support member so that the frying plate is suspended in the frying basket.

[0046] See Figure 5In this embodiment, a support member 124 is provided at the bottom of the frying plate 120, which is used to suspend the frying plate 120 in the frying basket 110. This allows hot air to circulate freely under the frying plate 120, further improving the utilization efficiency of hot air and optimizing the cooking effect.

[0047] In one specific embodiment, the support is configured as a spring sheet extending downward from the edge of the blasting plate. When the blasting plate is installed into the blasting basket, the spring sheet has a supporting force toward the side wall of the blasting basket to facilitate the fixing of the blasting plate.

[0048] In this embodiment, the support member 124 is configured as a spring extending downward from the edge of the frying plate 120. When the frying plate 120 is installed in the frying basket 110, the spring has a supporting force toward the side wall of the frying basket 110. This design not only facilitates the fixing of the frying plate 120, but also ensures that the frying plate 120 remains stable during cooking, avoiding deformation or displacement of the frying plate 120 due to the weight of the food.

[0049] In some embodiments, the cooking cavity is provided with ribs, which are configured to support the bottom of the frying basket so that the bottom of the frying basket is suspended above the cooking cavity to facilitate the circulation of airflow.

[0050] See Figures 2 to 4 The cooking cavity 101 is provided with a raised rib 1011, which is configured to support the bottom of the frying basket 110, so that the bottom of the frying basket 110 is suspended in the cooking cavity 101. This design provides a smoother path for the circulation of airflow, avoids the accumulation of hot air at the bottom of the frying basket 110, and ensures that hot air can circulate efficiently in the cooking cavity 101.

[0051] In some embodiments, a circulating air vent is provided on the side wall of the cooking cavity, and the air fryer is provided with a circulating cavity communicating with the circulating air vent, and a centrifugal fan is provided in the circulating cavity to generate circulating air.

[0052] In this embodiment, a circulating air vent 1012 is provided on the side wall of the cooking cavity 101, and the air fryer 100 is provided with a circulating cavity 130 communicating with the circulating air vent 1012. A centrifugal fan 131 is provided in the circulating cavity 130 to generate circulating air. The circulating air vent 1012 of the centrifugal fan 131 draws hot air out of the cooking cavity 101 to ensure the flow and circulation of air in the cooking cavity.

[0053] In one specific embodiment, the top of the cooking cavity has a hot air channel, and the top of the circulation cavity has a vent that communicates with the hot air channel. The hot air channel has hot air holes that face downward toward the cooking cavity.

[0054] In this embodiment, the top of the cooking cavity 101 has a hot air channel 140, and the top of the circulation cavity 130 is provided with a vent 132 that communicates with the hot air channel 140. The hot air channel 140 is provided with hot air holes 141 facing downward toward the cooking cavity 101. Hot air enters the cooking cavity 101 through the hot air holes 141 and acts directly on the surface of the food, so that the food can be cooked quickly.

[0055] In one specific embodiment, a heating tube is provided in the hot air channel and / or the circulation chamber.

[0056] In this embodiment, a heating tube 142 is provided in the hot air channel 140 and / or the circulation chamber 130. The heating tube 142 can be set alone in the hot air channel 140, or it can be set alone in the circulation chamber 130, or it can be set in both the hot air channel 140 and the circulation chamber 130. This embodiment does not impose any restrictions. The heating tube 142 is used to heat the circulating air generated by the centrifugal fan to form high-temperature hot air to heat the food.

[0057] The air fryer of this invention is designed with user habits and cleaning needs in mind. The frying basket 110 is detachably mounted inside the cooking chamber 101, allowing users to easily remove it for cleaning or replacement. The frying plate 120 is also detachably suspended inside the frying basket 110, allowing users to select different frying plates 120 according to different cooking needs, or to clean the frying plate 120 separately.

[0058] During assembly, the user first places the frying basket 110 into the cooking chamber 101, ensuring that the ribs 1011 can stably support the bottom of the frying basket 110. Then, the frying plate 120 is installed into the frying basket 110 via its bottom support 124, ensuring that the frying plate 120 is suspended within the frying basket 110. Finally, the air fryer 100 is turned on, and the air is heated by the heating tubes 142 in the hot air channel 140 and / or the circulation chamber 130, forming high-temperature hot air. The circulating air generated by the centrifugal fan 131 enters the cooking chamber 101 through the circulation vent 1012, achieving uniform circulation of hot air.

[0059] The air fryer of this invention demonstrates significant advantages in practical use. For example, when cooking French fries, the user places the fries on the food placement area 121 of the frying plate 120. Due to the radial array distribution of the ventilation holes 122, hot air can evenly pass through the fries, ensuring uniform heating and resulting in crispy on the outside and tender on the inside fries with an excellent taste. Simultaneously, due to the protruding structure 112 and the design of the dual oil collection areas, grease dripping from the fries is effectively collected in the first oil collection area 113 and the second oil collection area 114, preventing grease from entering the cooking chamber 101 and reducing cleaning workload.

[0060] After cooking, the user can easily remove the frying plate 120 from the frying basket 110 through the handle hole 123 to clean the grease in the first oil accumulation zone 113 and the second oil accumulation zone 114. Since both the frying plate 120 and the frying basket 110 are removable, the user can easily clean them separately, keeping the air fryer clean and hygienic.

[0061] The working process or principle of this utility model is as follows:

[0062] When the air fryer 100 is started, the centrifugal fan 131, driven by the motor, begins to operate, drawing air from the cooking chamber 101 into the circulation chamber 130 through the circulation vent 1012. Within the circulation chamber 130, the air comes into full contact with the heating element 142 and is heated to the set temperature. The heated air then enters the hot air channel 140 through the vent 132 and is evenly blown onto the food inside the cooking chamber 101 through the hot air holes 141. The hot air continuously circulates within the cooking chamber 101, removing moisture from the surface of the food, resulting in a crispy texture, while simultaneously cooking the food.

[0063] Through the above working process, the air fryer 100 of this utility model effectively prevents food residue and grease from falling from the air outlet 111 into the cooking chamber 101 while ensuring the capacity of the frying basket, thus achieving the purpose of easy cleaning and bringing users a more convenient and efficient cooking experience.

[0064] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
