Description

Technical Field

[0001] This invention relates to the field of air fryer technology, and in particular to a centralized air supply air fryer. Background Technology

[0002] An air fryer is a kitchen appliance that uses an air heating element and the hot air circulation it generates to bake food. Currently, air fryers on the market mainly consist of: a main body, fan blades, a heating element, and a detachable frying basket. The heating element is used to heat the air in the frying basket, causing the surface of the food to dehydrate and create a texture similar to that of fried food.

[0003] Existing air fryers can be mainly divided into the following two types:

[0004] One type exposes the heating element directly above the frying basket, with a fan blade installed above it. The fan blade is driven by a motor, and during use, the rotating fan blade works with the heating element to generate hot air that blows towards the frying basket, thus heating the food. However, during use, food grease will splatter onto the heating element and fan blade, making it very difficult to clean. This is not only unhygienic, but after repeated use, the residual grease will bake into an unpleasant odor.

[0005] Another option is to install a perforated air vent between the heating element and the frying basket. This air vent reduces the amount of grease produced during frying that adheres to the heating element and the hot air fan blades. However, users need to remove the air vent for cleaning, which is still cumbersome. Furthermore, this layered design increases the overall height of the air fryer, hindering its miniaturization.

[0006] Moreover, traditional fan blade designs have limitations. The air they generate is a cutting airflow, which is not conducive to forming a stable airflow inside to heat the food. In other words, it is difficult to form a stable airflow circulation, resulting in low heating efficiency for the food.

[0007] To address these issues, this invention presents a centralized air-flow air fryer to overcome the aforementioned technical problems. Summary of the Invention

[0008] To address the shortcomings of existing technologies, this invention provides a centralized airflow air fryer, which solves the problems of cumbersome and inconvenient cleaning operations of existing air fryers, while achieving stable airflow circulation inside the fryer, thereby improving cooking efficiency and user experience.

[0009] The objective of this invention is achieved through the following technical solution:

[0017] In one embodiment, a valve assembly is provided between the air inlet pipe and the air guide shroud, the valve assembly opening or blocking the hot air passage;

[0018] When the motor starts, the valve assembly opens, and airflow enters the hot air passage of the air guide shroud through the air inlet pipe; when the motor stops, the valve assembly closes to prevent airflow from the hot air passage from entering the air inlet pipe.

[0019] In one embodiment, the port of the air inlet duct is provided with a filter screen to prevent dust, insects, etc. from entering the air inlet duct.

[0020] In one embodiment, the main body is provided with a controller that is electrically connected to the motor and the heater. The controller adjusts the speed of the motor to change the airflow velocity in the air inlet duct.

[0021] In one embodiment, an air diffuser hole is provided on the side wall of the air inlet duct, and part of the airflow in the air inlet duct is blown into the interior of the main body through the air diffuser hole, thereby cooling the outer wall of the main body.

[0022] In one embodiment, the main body is provided with a plurality of heating chambers, the number of frying baskets is the same as the number of heating chambers, and each frying basket corresponds to one heating component;

[0023] The air inlet duct has a main duct and multiple branch ducts. The number of branch ducts corresponds to the number of heating chambers, and all branch ducts are connected to the main duct.

[0024] In one embodiment, the number of heating chambers is two, which are horizontally arranged side by side within the main body, or the two heating chambers are vertically arranged vertically within the main body.

[0038] This invention provides a centralized airflow air fryer 10, aiming to solve the problems of cumbersome and inconvenient cleaning operations of existing air fryers, while achieving stable airflow circulation inside the fryer to improve cooking efficiency and user experience. Figure 1 , Figure 2 and Figure 3 As shown, the centralized air supply air fryer 10 includes: a main body 100, a centralized air supply component 200, a heating component 300, and a frying basket 400. The main body 100 has a heating chamber 101, and the frying basket 400 is detachably housed in the heating chamber 101. The heating component 300 is installed inside the main body 100 and located above the heating chamber 101.

[0039] Among them, such as Figure 4As shown, the centralized air supply assembly 200 includes an air inlet pipe 210 and a motor 220. The air inlet pipe 210 is installed inside the main body 100 and communicates with the outside of the main body 100. The motor 220 is provided with blades and can cause the airflow in the air inlet pipe 210 to flow.

[0040] like Figure 5 As shown, the heating assembly 300 includes an air guide shroud 310 and a heater 320. The air guide shroud 310 is located between the air inlet pipe 210 and the heating chamber 101. A hot air passage 301 is formed inside the air guide shroud 310, and the heater 320 is housed within the hot air passage 301. The air guide shroud 310 is provided with a lower baffle 311, which covers the heating chamber 101. During operation, the lower baffle 311 acts as a shield for the heater 320, thereby preventing grease from splashing onto the heater 320. The specific working principle will be explained below.

[0041] In this embodiment, as Figure 5 As shown, the end face of the air guide shroud 310 forms an air inlet 302 that communicates with the hot air passage 301, and the air inlet 302 is located at the edge of the lower baffle 311. In use, the airflow in the hot air passage 301 is heated by the heater 320 and then enters the heating chamber 101 through the air inlet 302. Moreover, the air guide shroud 310 is provided with an upper baffle 312 and a connecting pipe 313. The connecting pipe 313 connects the upper baffle 312 and the lower baffle 311, and the connecting pipe 313 forms an air outlet passage 303.

[0042] Preferred, such as Figure 5 and Figure 7 As shown, the air inlets 302 are evenly distributed around the lower baffle 311, and the air inlets 302 are attached to the side wall of the frying basket 400.

[0043] Preferred, such as Figure 6 As shown, the main body 100 has an exhaust pipe 110 inside, which connects the air outlet channel 303 to the outside of the main body 100. In use, the hot air in the heating chamber 101 will be discharged through the air outlet channel 303 to the exhaust pipe 110, and then discharged to the outside through the exhaust pipe 110.

[0044] The working principle of the centralized air-supply air fryer 10 of the present invention is explained below in conjunction with the above structure, for reference. Figure 6 and Figure 7 As shown:

[0045] Initially, the user places the food to be heated into the frying basket 400, and then installs the frying basket 400 into the heating chamber 101 of the main body 100. At this time, the frying basket 400 cooperates with the air guide 310 to form a relatively sealed space inside the frying basket 400;

[0046] Subsequently, the centralized air-feed air fryer 10 is activated. The motor 220 drives outside air into the main body 100. The air passes through the air inlet duct 210 and enters the hot air channel 301 of the air guide hood 310, forming a flowing airflow. Simultaneously, the heater 320 is energized, generating high temperatures that heat the surrounding airflow. The flowing airflow further passes through the air inlet 302, carrying the heat into the frying basket 400. During this process, the hot airflow first flows downwards along the side wall of the frying basket 400, then, after being blocked by the bottom of the basket 400, it converges towards the center and flows upwards, thus evenly heating the food inside the basket 400. The flow path of the hot airflow within the frying basket 400 is as follows: Figure 7 As shown;

[0047] Next, the hot airflow inside the frying basket 400 enters the exhaust pipe 110 through the air outlet 303 of the connecting pipe 313, and is then discharged to the outside of the main body 100 through the exhaust pipe 110. During this process, the hot airflow heats the food, causing the surface of the food to dehydrate and create a texture similar to frying. During use, the flow rate of the hot airflow inside the frying basket 400 can be controlled by adjusting the speed of the motor 220, and the temperature and heating time of the heater 320 can be adjusted in conjunction with this to adapt to the cooking requirements of different ingredients.

[0048] It is important to emphasize that, compared with existing technologies, the centralized airflow air fryer 10 of the present invention enables convenient and quick cleaning. Specifically, in existing air fryers, during cooking, the grease produced by the food splashes onto the perforated air filter or heater. Because the surface of the air filter or heater is uneven and has many dead corners, it is not easy for users to clean it with a cloth, and sometimes the air filter or heater needs to be disassembled for cleaning, making the cleaning process cumbersome. In the present invention, however, the grease produced by the food during cooking splashes onto the lower baffle 311. Since the lower baffle 311 is not perforated or wrinkled and has a smooth surface, users can easily wipe away the grease from the lower baffle 311 with a cloth after cooking, achieving convenient cleaning.

[0049] It is worth further explaining that the air inlet 302 is located at the edge of the lower baffle 311, and the hot airflow blows downward along the side wall of the frying basket 400 during cooking. In this way, the flowing hot airflow can prevent the oil fumes generated by the food from entering the hot air channel 301 from the air inlet 302, which would cause the heater 320 to be contaminated with oil.

[0050] Furthermore, it should be noted that the air fryer 10 of the present invention has a centralized air supply assembly 200 to overcome the problem of unstable airflow during cooking in traditional fryers. Specifically, in traditional fryers, the fan blades are closely fitted to the heater 320 and exposed above the heating chamber 101. During cooking, the cutting airflow generated by the fan is not conducive to being stably and evenly transmitted to the surface of the food, making it difficult to form a stable airflow circulation. In the present invention, however, the fan blades are mounted on the motor 220. The airflow generated by the motor 220 passes through the air inlet duct 210 and the hot air channel 301, during which the airflow gradually becomes stable, and finally forms a stable airflow circulation in the frying basket 400.

[0051] In this embodiment, as Figure 7 As shown, a valve assembly 230 is provided between the air inlet duct 210 and the air guide shroud 310. The valve assembly 230 has an opening and closing cover structure similar to that of a vehicle throttle valve, which is used to open or close the hot air passage 301. When the motor 220 starts, the valve assembly 230 opens, connecting the air inlet duct 210 and the air guide shroud 310, and airflow enters the hot air passage 301 of the air guide shroud 310 through the air inlet duct 210. When the motor 220 stops, the valve assembly 230 closes to prevent airflow from the hot air passage 301 from entering the air inlet duct 210. In this way, the hot airflow in the air guide shroud 310 and the heating chamber 101 will not flow backward into the centralized air supply assembly 200, avoiding the motor 220 from being affected by high temperatures, thereby extending its service life.

[0052] Preferably, a filter screen 211 is provided at the port of the air inlet duct 210 (e.g., Figure 2 As shown), the filter 211 is used to prevent dust, insects, etc. from entering the air inlet duct 210, so as to ensure that the food is clean and hygienic during the cooking process.

[0053] Preferably, the main body 100 is equipped with a controller (not shown in the figure), which is electrically connected to the motor 220 and the heater 320. The controller adjusts the speed of the motor 220 to change the airflow velocity in the air inlet duct 210, thereby adjusting the flow rate of the hot air in the heating chamber 101 and the frying basket 400.

[0054] Furthermore, in existing air fryers, the outer shell heats up due to the hot airflow during cooking, making it easy for users to get burned when they touch it. Therefore, in one embodiment, the centralized air supply assembly 200 has been improved. Specifically, as... Figure 4 As shown, an air diffuser hole 212 is provided on the side wall of the air inlet pipe 210. Part of the airflow in the air inlet pipe 210 is blown into the interior of the main body 100 through the air diffuser hole 212, thereby cooling the outer wall of the main body 100.

[0055] During use, the airflow inside the air inlet duct 210 is at room temperature. During cooking, most of the airflow inside the air inlet duct 210 will enter the hot air channel 301 of the air guide hood 310, and only a small portion of the airflow will be blown towards the outer wall of the main body 100 through the air diffuser 212. In this way, this part of the airflow can reduce the heat transfer efficiency between the frying basket 400 and the outer wall of the main body 100, thereby reducing the temperature of the outer wall of the main body 100 and preventing users from being burned by accidental contact.

[0056] In other embodiments, the centralized air-cooled air fryer 10 can also be configured as a multi-cavity structure. The main body 100 is provided with multiple heating chambers 101, the number of frying baskets 400 is the same as the number of heating chambers 101, and each frying basket 400 corresponds to a heating component 300.

[0057] Among them, such as Figure 8 As shown, the air inlet duct 210 is provided with a main duct 213 and multiple branch ducts 214. The number of branch ducts 214 corresponds to the number of heating chambers 101, and all branch ducts 214 are connected to the main duct 213. Each branch duct 214 is connected to the air guide shroud 310 of a heating component 300. Meanwhile, the motor 220 is located inside the main duct 213.

[0058] In use, the motor 220 causes airflow within the main duct 213. Ideally, the airflow will flow evenly into each branch duct 214, and then reach the corresponding air guide shroud 310 and heating chamber 101. In this way, the centralized airflow air fryer 10 of the present invention can cook multiple ingredients simultaneously, improving work efficiency.

[0059] like Figure 8 and Figure 9 As shown, in some embodiments, there are two heating chambers 101. These two heating chambers 101 can be arranged horizontally side-by-side within the main body 100, or vertically arranged vertically within the main body 100. For the horizontal side-by-side arrangement, although the centralized air-flow air fryer 10 occupies a larger area, its height is lower, which is advantageous for use in scenarios with limited vertical space. For the vertical arrangement, although the centralized air-flow air fryer 10 is taller overall, its area is smaller, which is advantageous for use on small, compact kitchen countertops. Of course, there can be multiple heating chambers 101, and these multiple heating chambers 101 can be stacked in both horizontal and vertical arrangements, thus facilitating rapid cooking and serving.

[0060] It is worth emphasizing that, compared with existing air fryers, the air fryer 10 of the present invention uses a centralized air supply assembly 200 for air supply, which only requires one motor 220 to achieve the flow of hot air in multiple heating chambers 101. Existing air fryers, when achieving multi-chamber heating, require each chamber to be equipped with a motor and a fan blade structure, thereby increasing the overall height of the fryer and making it difficult to achieve miniaturization.

[0061] In summary, the centralized air supply air fryer 10 of the present invention can solve the problems of cumbersome and inconvenient cleaning operations of existing air fryers, while achieving stable airflow circulation inside the air fryer, thereby improving cooking efficiency and user experience.

[0062] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
