Description

Technical Field

[0001] The invention relates to the technical field of air fryers, and in particular to a centralized air supply type air fryer. Background Art

[0002] An air fryer is a kitchen appliance that uses an air heating component and the hot air circulation it generates to bake food. Currently, the air fryers on the market mainly include: a main body, a fan blade, a heating component, and a detachable frying basket. The heating component is used to heat the air in the frying basket to dehydrate the surface of the food to form a fried taste.

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

[0004] One method is to expose the heating component directly above the frying basket, and a fan is also set above the heating component. The fan is driven by a motor. When in use, the rotating fan cooperates with the heating component to generate hot air blowing toward the frying basket, thereby heating the food. However, during use, the grease of the food will splash onto the heating tube and the fan, which is very difficult to clean. It is not only unhygienic, but also will bake out the odor of the residual grease after repeated use;

[0005] Another method is to install a hollow air filter between the heating component and the frying basket. The air filter can reduce the grease generated during frying from adhering to the heating device and the hot air blades. However, when cleaning, the user needs to remove the air filter for cleaning, which is still cumbersome. In addition, the stacked structure design will increase the height of the entire air fryer, which is not conducive to miniaturization.

[0006] Moreover, the traditional fan blade design has limitations. The wind it produces is a cutting airflow, which is not conducive to forming a smooth airflow inside to heat food. In other words, it is difficult to form a stable airflow circulation, and the food heating efficiency is low.

[0007] To this end, the present invention designs a centralized air supply type air fryer to overcome the above technical problems. Summary of the invention

[0008] In view of the deficiencies in the prior art, the present invention provides a centralized air supply type air fryer to solve the problem that the cleaning operation of the existing fryer is cumbersome and inconvenient, while realizing stable circulation of airflow inside the fryer, thereby improving cooking efficiency and user experience.

[0013] In one embodiment, the end surface of the air guide cover forms an air inlet that penetrates the hot air channel. When in use, the airflow in the hot air channel is heated by the heater and then enters the heating chamber through the air inlet.

[0017] In one embodiment, a valve assembly is provided between the air inlet pipe and the air guide cover, and the valve assembly opens or blocks the hot air channel;

[0018] When the motor starts, the valve assembly opens, and air flows from the air inlet pipe into the hot air channel of the air guide cover; when the motor stops, the valve assembly closes to prevent the air flow in the hot air channel from entering the air inlet pipe.

[0019] In one of the embodiments, a filter is provided at the port of the air inlet pipe, and the filter is used to prevent dust, mosquitoes and the like from entering the air inlet pipe.

[0020] In one of the embodiments, a controller is disposed in the main body, the controller is electrically connected to the motor and the heater, and the controller changes the air flow rate in the air inlet duct by adjusting the motor speed.

[0021] In one of the embodiments, a side wall of the air inlet pipe is provided with air diffusion holes, and part of the air flow in the air inlet pipe is blown toward the interior of the main body through the air diffusion holes, thereby cooling the outer wall of the main body.

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

[0023] The air inlet pipe is provided with a main pipe and a plurality of branch pipes, the number of the branch pipes corresponds to the number of the heating chambers, and the plurality of branch pipes are all connected to the main pipe, and each of the branch pipes is connected to an air guide cover of the heating component; the motor is arranged in the main pipe.

[0038] The present invention provides a centralized air supply type air fryer 10, which aims to solve the problem that the cleaning operation of the existing air fryer is complicated and inconvenient, and at the same time realizes the stable circulation of air flow inside the fryer to improve the cooking efficiency and user experience. Figure 1 , Figure 2 and Figure 3 As shown, the centralized air supply type 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 is provided with a heating chamber 101, the frying basket 400 is detachably accommodated in the heating chamber 101, and the heating component 300 is installed inside the main body 100 and is located above the heating chamber 101.

[0039] Among them, 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 the motor 220 can promote the flow of air in the air inlet pipe 210 .

[0040] like Figure 5 As shown, the heating assembly 300 includes an air guide cover 310 and a heater 320. The air guide cover 310 is arranged between the air inlet pipe 210 and the heating chamber 101. A hot air channel 301 is formed in the air guide cover 310, and the heater 320 is accommodated in the hot air channel 301. The air guide cover 310 is provided with a lower baffle 311, and the lower baffle 311 is arranged above the heating chamber 101. When working, the lower baffle 311 shields the heater 320, thereby preventing grease from splashing onto the heater 320. The specific working principle will be described below.

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

[0042] Preferably, 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] Preferably, Figure 6 As shown, an exhaust pipe 110 is provided inside the main body 100, and the exhaust pipe 110 connects the air outlet channel 303 with the outside of the main body 100. When in use, the hot air flow in the heating chamber 101 will be discharged to the exhaust pipe 110 through the air outlet channel 303, and then discharged to the outside by the exhaust pipe 110.

[0044] In combination with the above structure, the working principle of the centralized air supply type air fryer 10 of the present invention is described as follows. 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 cover 310, so that a relatively closed space is formed inside the frying basket 400;

[0046] Subsequently, the centralized air supply type air fryer 10 is started, and the motor 220 drives the outside air into the main body 100, and the air passes through the air inlet pipe 210 and enters the hot air channel 301 of the air guide cover 310, forming a flowing airflow. At the same time, the heater 320 is powered on to generate high temperature, thereby heating the surrounding airflow; the flowing airflow will further pass through the air inlet 302, and bring heat into the frying basket 400. During this period, the hot air flow will first flow downward along the side wall of the frying basket 400, and after being blocked by the bottom of the frying basket 400, it will move toward the center and flow upward, thereby evenly heating the food in the frying basket 400. The flow path of the hot air flow in the frying basket 400 is as follows: Figure 7 As shown;

[0047] Then, the hot air flow in the frying basket 400 will enter the exhaust pipe 110 through the air outlet channel 303 of the connecting pipe 313, and then be discharged to the outside of the main body 100 by the exhaust pipe 110. During this period, the hot air flow heats the food, dehydrates the surface of the food to form a fried taste. During use, the flow rate of the hot air flow in the frying basket 400 can be controlled by adjusting the speed of the motor 220, and the temperature of the heater 320 and the heating time can be adjusted at the same time to meet the cooking requirements of different food.

[0048] It should be emphasized that compared with the prior art, the centralized air supply type air fryer 10 of the present invention can achieve convenient and quick cleaning operation. Specifically, during the cooking process of the prior art air fryer, the grease generated by the food will splash onto the hollowed-out air fryer or heater. Since the surface of the air fryer or heater is uneven and there are many dead corners, it is difficult for the user to clean it easily with a rag, and the air fryer or heater may even need to be disassembled for cleaning, which makes the cleaning operation cumbersome. In the present invention, the grease generated by the food during the cooking process will splash onto the lower baffle 311. Since the lower baffle 311 is not hollowed out or wrinkled and has a smooth surface, after cooking, the user only needs to use a rag to easily wipe off the grease on the lower baffle 311, achieving convenient cleaning.

[0049] It is worth further explaining that the air inlet 302 is provided with the edge of the lower baffle 311, and the hot air flow blows downward along the side wall of the frying basket 400 during cooking. In this way, the flowing hot air flow can prevent the oil smoke generated by the food from entering the hot air channel 301 from the air inlet 302 in the opposite direction, causing the heater 320 to be stained with oil.

[0050] In addition, 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 in traditional fryers during cooking. Specifically, the fan blades of traditional fryers are tightly fitted with the heater 320 and exposed above the heating chamber 101. The cutting airflow generated during cooking is not conducive to the stable and uniform transfer to the surface of the food, and it is difficult to form a stable airflow circulation; in the present invention, the fan blades are set on the motor 220, and the airflow generated by the motor 220 will pass through the air inlet pipe 210 and the hot air channel 301. During this period, the airflow gradually tends to be stable, and finally a stable airflow circulation is formed in the frying basket 400.

[0051] In this embodiment, if Figure 7 As shown, a valve assembly 230 is provided between the air inlet pipe 210 and the air guide cover 310. The valve assembly 230 has an opening and closing cover structure similar to a vehicle throttle, and is used to open or block the hot air channel 301. When the motor 220 is started, the valve assembly 230 is opened, the air inlet pipe 210 is connected to the air guide cover 310, and the air flow enters the hot air channel 301 of the air guide cover 310 from the air inlet pipe 210; when the motor 220 stops, the valve assembly 230 is closed to prevent the air flow in the hot air channel 301 from entering the air inlet pipe 210. In this way, the hot air flow in the air guide cover 310 and the heating chamber 101 will not reversely enter the centralized air supply assembly 200, preventing the motor 220 from being affected by high temperature, thereby extending its service life.

[0052] Preferably, a filter screen 211 (such as Figure 2 As shown), the filter 211 is used to prevent dust, mosquitoes, etc. from entering the air inlet duct 210 to ensure that the ingredients are clean and hygienic during the cooking process.

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

[0054] Furthermore, during the cooking process of the existing air fryer, the shell will be affected by the hot air flow and the temperature will rise. At this time, when the user touches the shell of the fryer, it is easy to get burned. For this reason, in one embodiment, the centralized air supply component 200 is improved. Specifically, Figure 4 As shown, a diffusion hole 212 is opened on the side wall of the air inlet pipe 210 , and part of the air flow in the air inlet pipe 210 is blown toward the inside of the main body 100 through the diffusion hole 212 , thereby cooling the outer wall of the main body 100 .

[0055] When in use, the airflow in the air inlet pipe 210 is at room temperature. During cooking, most of the airflow in the air inlet pipe 210 will enter the hot air channel 301 of the air guide cover 310, and only a small part of the airflow will be blown toward the outer wall of the main body 100 through the air diffusion holes 212. In this way, this part of the flowing 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 to avoid accidental burns to the user.

[0056] In other embodiments, the centralized air supply type air fryer 10 can also be configured as a multi-cavity structure. The main body 100 is provided with a plurality of 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 assembly 300 .

[0057] Among them, Figure 8 As shown, the air inlet pipe 210 is provided with a main pipe 213 and a plurality of branch pipes 214, the number of the branch pipes 214 corresponds to the number of the heating chambers 101, and the plurality of branch pipes 214 are all connected to the main pipe 213, and each branch pipe 214 is connected to an air guide cover 310 of the heating assembly 300. At the same time, the motor 220 is arranged in the main pipe 213.

[0058] When in use, the motor 220 promotes the airflow in the main pipe 213. Ideally, the airflow will flow evenly into each branch pipe 214, and then reach the corresponding air guide cover 310 and heating chamber 101. In this way, the centralized air supply type air fryer 10 of the present invention can cook multiple ingredients at the same time, thereby improving work efficiency.

[0059] like Figure 8 and Fig. 9 As shown, in some embodiments, the number of heating chambers 101 is two, and the two heating chambers 101 can be distributed horizontally side by side in the main body 100, or vertically distributed up and down in the main body 100. For the horizontal side-by-side distribution, although the centralized air supply type air fryer 10 occupies a large area, its height is low, which is conducive to use in scenes with insufficient height space; for the vertical up and down distribution, although the centralized air supply type air fryer 10 is overall high, it occupies a small area, which is conducive to use on a small and compact kitchen stove. Of course, the number of heating chambers 101 can be multiple, and multiple heating chambers 101 are compatible with the stacking method of horizontal side-by-side distribution and vertical up and down distribution, which is conducive to fast cooking and serving.

[0060] It is worth emphasizing that, compared with the air fryer in the prior art, the air fryer 10 of the present invention adopts a centralized air supply assembly 200 for air supply, and only one motor 220 is required to realize the hot air flow of multiple heating chambers 101. When the air fryer in the prior art realizes multi-cavity heating, each cavity needs to be equipped with a motor and a fan blade structure, thereby increasing the overall height of the fryer, which is not conducive to miniaturization.

[0061] In summary, the centralized air supply type air fryer 10 of the present invention can solve the problem that the cleaning operation of the existing fryer is complicated and inconvenient, and at the same time realize the stable circulation of airflow inside the fryer, thereby improving cooking efficiency and user experience.

[0062] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
