Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more, unless otherwise clearly specified.

[0032] In this application, unless otherwise clearly specified and limited, the terms "installation", "connection", "fixation" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, an indirect connection through an intermediate medium, or the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0033] See also Figures 1 to 10 As shown, the embodiment of the present application discloses an air fryer, which includes a fryer body 1 and a frying basket 2. The fryer body 1 includes an outer shell, an electronic control unit connected to the outer shell, a control panel 6 and an inner pot 103 connected to the outer shell. The fryer body 1 has at least one cooking cavity 100, which is formed in the inner pot 103. The user side of the fryer body 1 is provided with an insertion port 101 which is connected to the cooking cavity 100 and allows the frying basket 2 to be inserted into or out of the cooking cavity 100, and the number of the insertion ports 101 matches the number of the cooking cavities 100. At least one heating component 3 corresponding to the cooking cavity 100 is connected to the fryer body 1, that is, one cooking cavity 100 corresponds to one heating component 3.

[0034] In this embodiment, each heating assembly 3 includes an electric heating element 300 and a fan assembly 301. Figure 2 , Figure 3 and Figure 4 As shown, the fan assembly 301 is connected to the side of the fryer body 1 away from the insertion port 101 and communicated with the cooking cavity 100, that is, the fan assembly 301 is connected to the back of the fryer body 1, or connected to the side away from the user side, or the side where the insertion port 101 of the fryer body 1 is located is opposite to the side where the fan assembly 301 of the fryer body 1 is located. The fan assembly 301 has an upwardly extending air outlet channel 4, and the air outlet channel 4 is provided with an air outlet 400 communicated with the upper part of the cooking cavity 100; in addition, the electric heating element 300 is separated from the fan assembly 301, and the electric heating element 300 is connected to the upper part of the cooking cavity 100 and arranged corresponding to the air outlet 400, and the electric heating element 300 is used to heat the airflow blown out of the air outlet 400 and diffuse the heated hot airflow downward into the cooking cavity 100.

[0035] Further in the present embodiment, the control panel 6 controls the electric heating element 300 to generate heat, and the control panel 6 controls the fan assembly 301 to work. The fan assembly 301 generates airflow, and the airflow is blown upward along the air outlet channel 4 through the air outlet 400. When the blown airflow passes through the electric heating element 300, the airflow temperature increases to form a hot airflow. The formed hot airflow diffuses downward into the cooking cavity 100 and reaches the surface of the food under the action of the airflow of the fan assembly 301, and at the same time, the heat in the cooking cavity 100 is absorbed by the fan assembly 301. Therefore, a circulation of hot airflow is formed in the cooking cavity 100, thereby performing cyclic heating and baking on the food.

[0036] Furthermore, in the present embodiment, the air fryer separately arranges the electric heating element 300 and the fan assembly 301 of the heating assembly 3, that is, the fan assembly 301 is arranged on the side of the fryer body 1 away from the insertion port 101 and is connected to the cooking cavity 100, the electric heating element 300 is connected above the cooking cavity 100 and arranged corresponding to the air outlet 400 of the air outlet channel 4 of the fan assembly 301, and the airflow generated by the fan assembly 301 is blown out through the air outlet 400 of the air outlet channel 4 and is heated by the electric heating element 300 when passing through the electric heating element 300, and the heated hot airflow is diffused downward into the cooking cavity 100 under the action of the airflow; in this way, the transmission path of the hot airflow to the surface of the food is shortened, the hot airflow transmission time is short and can quickly reach the surface of the food, and the hot airflow has less energy loss in the entire transmission path; therefore, the air fryer can reduce the energy consumption of heat during the transmission process, so that the baking efficiency is high and the taste of the food is good.

[0037] For example, in the related art, the fan assembly transports the hot air flow generated by the electric heating element to the top of the cooking cavity through the air outlet channel, and then diffuses downward from the top of the cooking cavity into the cooking cavity; in the present embodiment, the hot air flow generated by the electric heating element 300 under the action of the airflow of the fan assembly 301 does not pass through the air outlet channel 4 but directly diffuses downward into the cooking cavity 100, so as to reach the surface of the food to bake the food; therefore, compared with the air fryer of the related art, the hot air flow generated by the electric heating element 300 flows to the surface of the food in the cooking cavity 100, the length of the transmission path of the hot air flow is shortened by at least half, and the transmission time of the hot air flow is saved by at least half.

[0038] It is not difficult to understand that the electric heating element 300 is an electric heating wire or an electric heating tube, which is electrically connected to the electronic control unit of the air fryer, generates heat when powered on, and when the airflow passes through the electric heating element 300, it can quickly heat up and form a hot airflow under the action of the airflow.

[0039] In this embodiment, the fan assembly 301 includes a motor 302 connected to the fryer body 1 and a fan blade 303 disposed in the air outlet channel 4 and connected to the rotating shaft of the motor 302. A through hole 304 communicating with the cooking cavity 100 is disposed on the side wall of the air outlet channel 4 close to the cooking cavity 100, and a mesh cover 305 covering the through hole 304 is connected to the inner wall of the cooking cavity 100. Specifically, the air outlet channel 4 is located between the motor 302 and the cooking cavity 100, and the air outlet channel 4 includes a first plate member and a second plate member disposed vertically, such as Figure 4As shown, the second plate is located on a side close to the cooking cavity 100, and the space between the first plate and the second plate forms an upwardly extending air outlet channel 4, the wind blade 303 of the fan assembly 301 is located in the air outlet channel 4, and the second plate is provided with a through hole 304 connected to the cooking cavity 100; the air or hot air flow in the cooking cavity 100 is sucked into the air outlet channel 4 under the action of the rotation of the wind blade 303, and is blown upward through the air outlet 400 along the air outlet channel 4 under the action of the wind blade 303. It is not difficult to understand that the lower end of the air outlet channel 4 is a closed end to ensure that the air flow in the air outlet channel 4 can flow upward quickly, thereby improving the baking efficiency.

[0040] Further in this embodiment, the fan blade 303 of the fan assembly 301 is an axial flow fan blade 303, and the center of the fan blade 303 is aligned with the through hole 304 on the side wall of the air outlet channel 4. It is not difficult to understand that the back of the air fryer inner pot 103 is provided with a hole that matches the through hole 304 on the air outlet channel 4, or the through hole 304 on the air outlet channel 4 and the hole on the back of the air fryer inner pot 103 are the same hole or share a through hole 304. The mesh cover 305 covering the through hole 304 can prevent food from entering the fan assembly 301.

[0041] For example, Figure 4 and Fig.10 As shown, the fan blade 303 includes two annular plates 306 spaced apart in the axial direction, and a plurality of arc-shaped blades 307 distributed in the circumferential direction are connected between the two annular plates 306. The central hole of the annular plate located on the side close to the cooking cavity is coaxial with the through hole 304, and the central hole of the annular plate located on the side away from the cooking cavity is connected to the rotating shaft of the motor 302. Compared with the fan of the prior art at the same speed, the fan blade 303 has a larger air output and stronger wind force, thereby increasing the flow rate and flow speed of the air flow and improving the baking efficiency.

[0042] It can be understood that the frying basket 2 of this embodiment includes a panel connected to the insertion port 101, a food basket connected to the inner side of the panel for holding food, and a handle installed on the outer side wall of the panel, and the panel can be connected to a transparent window; the top two sides of the food basket are provided with outward flanges, and the two opposite inner walls of each cooking cavity 100 are provided with a group of slots extending along the depth direction of the cooking cavity 100, and the flanges on both sides of the frying basket 2 can be slidably inserted into the group of slots. The back of the food basket is provided with a plurality of ventilation holes, and the plurality of ventilation holes are arranged near the lower part of the back of the food basket, so that heat can pass through the food, making the food at the bottom of the food basket easier to cook, thereby improving the baking efficiency.

[0043] It is easy to understand that the fan assembly 301 is installed on the back of the fryer body 1, and the airflow generated by the fan assembly 301 is blown to the top of the cooking cavity 100 through the air outlet channel 4 and the air outlet 400. The wind pressure and wind speed are higher in the area above the cooking cavity 100, and the wind pressure and wind speed are relatively lower in the area farther away from the fan assembly 301. In this way, the heat or heat energy of the hot air flow heated by the electric heating unit is uneven in the front and back of the cooking cavity 100, thereby affecting the baking effect and baking efficiency of the food. For this reason, in this embodiment, if Figure 2 , Figure 3 and Figure 4 As shown, a deflector 5 connected to the cooking cavity 100 is connected above each cooking cavity 100, and the deflector 5 is extended from the inside to the outside along the depth direction of the cooking cavity 100, and the inner end of the deflector 5 is connected to the air outlet 400, and the electric heating element 300 is arranged in the deflector 5. The deflector 5 is an independent flat component independent of the cooking cavity 100. It is arranged above the cooking cavity 100, and can quickly gather the airflow generated by the fan assembly 301, increase the overall air pressure of the airflow, and enable the electric heating element 300 to quickly heat the airflow gathered in the deflector 5, thereby improving the heating efficiency of the airflow, and enable the hot airflow diffused downward in the deflector 5 to quickly and evenly reach the surface of the food, thereby improving the baking efficiency.

[0044] The inner end of the air guide 5 forms an air inlet 500 connected to the air outlet 400. It is not difficult to understand that the air outlet 400 blows the airflow of the air inlet 500 of the air guide 5. Under the action of air pressure, the airflow will be concentrated and blown into the air guide 5 quickly, which will cause the electric heating element 300 to heat the airflow unevenly, so that the temperature of the hot air entering the cooking cavity 100 is uneven, affecting the baking effect. For this reason, in this embodiment, if Figure 2 , Figure 4 and Figure 5 As shown, a diverter plate 505 is connected to the air inlet 500, and the diverter plate 505 is used to disperse the airflow entering the air inlet 500 into the air guide cover 5. The arrangement of the diverter plate 505 can disperse the concentrated airflow entering the air inlet 500 into multiple airflows and guide them into the air guide cover 5, so that the airflow can be evenly and fully contacted with the electric heating element 300, which not only improves the heating efficiency of the airflow, but also makes the temperature of the hot airflow entering the cooking cavity 100 uniform, so as to achieve a good baking effect and avoid partial burning of the food.

[0045] For example, Figure 5 , Figure 7 and Figure 8As shown, the diverter plate 505 is a whole plate bent into a wave shape and arranged along the width direction of the air inlet 500, and a guide channel 506 for guiding the airflow into the guide cover 5 is formed between two adjacent bent parts of the diverter plate 505. Compared with the guide grille formed by punching in the prior art, the diverter plate 505 can form more guide channels 506, so that the airflow is dispersed into more small airflows, so that the airflow is fully in contact with the electric heating element 300.

[0046] In other embodiments, the diverter plate 505 may also adopt other structures, such as a plurality of guide vanes vertically connected to the air inlet 500 and spaced apart, with guide channels formed between adjacent guide vanes.

[0047] It is easy to understand that in this embodiment, the electric heating element 300 is horizontally arranged in the air deflector 5, and the air inlet 500 is located on one side of the electric heating element 300, and the closer to the air inlet 500 in the air deflector 5, the faster the air flow speed and the higher the air pressure, and the farther away from the air inlet 500, the slower the air flow speed and the lower the air pressure; therefore, when the electric heating element 300 heats up, the area close to the air inlet 500 dissipates heat quickly, while the area far away from the air inlet 500 dissipates heat slowly, which results in uneven heat dissipation of the electric heating element 300, resulting in uneven temperatures of the hot air flow entering the cooking cavity. For this reason, in this embodiment, Figure 7 , Figure 8 and Fig. 9 As shown, a heat sink 507 that fits the top of the electric heating element 300 is connected to the electric heating element 300, and the heat sink 507 is connected to the side of the electric heating element 300 close to the air inlet 500. In other words, the heat sink 507 may not completely cover the electric heating element 300, but only cover the side of the electric heating element 300 close to the air inlet 500, so that the heat sink 507 is exposed on the side of the electric heating element 300 away from the air inlet 500; the setting of the heat sink 507 allows the heat of the electric heating element 300 to be quickly transferred to the heat sink 507, thereby accelerating the heat dissipation of the electric heating element 300, so that the overall heat dissipation of the electric heating element 300 is uniform, that is, avoiding the defects of concentrated heat and slow heat dissipation of the electric heating element 300, and improving the baking efficiency.

[0048] For example, Figure 7 As shown, the shape of the heat sink 507 matches the shape of the air deflector 5 and is connected to the side of the electric heating element 300 close to the air inlet 500 by screws. The heat sink 507 is evenly distributed with a plurality of heat dissipation holes.

[0049] Further, in this embodiment, the air deflector 5 is connected to a baffle 503 extending downward along the circumferential direction, and the two ends of the baffle 503 are respectively connected to the two sides of the air inlet 500, so that the baffle 503 is arranged on the air deflector 5 to form a guide cavity corresponding to the air inlet 500. The electric heating element 300 and the heat sink 507 are both arranged in the guide cavity. Specifically, the air deflector 5 includes a top plate 501 and a bottom plate 502 connected to the top plate 501 or the bottom of the top plate 501, the baffle 503 is connected to the bottom plate 502, and the air inlet 500 is arranged on the bottom plate 502; Figure 5 , Figure 6 and Figure 7 As shown, the end of the baffle 503 away from the fan assembly 301 is set as a closed end, and the closed end is set in an arc shape. In this way, the airflow blown out from the air outlet 400 of the air outlet channel 4 first enters the deflector 5, and does not directly enter the cooking cavity 100. The airflow gathers in the deflector 5 and increases in temperature under the heating of the electric heating element 300. The generated hot air flow is evenly diffused from top to bottom into the cooking cavity 100 under the action of the fan assembly 301, thereby effectively avoiding the defects of uneven cooking of ingredients, long baking time and poor taste caused by inconsistent flow speed or air pressure of the hot air flow entering the cooking cavity 100. In addition, the closed end of the baffle 503 is set in an arc shape. After the airflow from the air outlet 400 enters the deflector cavity of the deflector 5, the hot air flow will generate a vortex or swirl in the deflector cavity, and the airflow can fully contact and heat with the electric heating element 300, and the increase in air pressure increases the downward diffusion speed of the hot air flow.

[0050] Further in this embodiment, Figure 6 and Figure 7 As shown, a side of the bottom plate 502 close to the insertion port 101 is provided with a wind shield 504 that bends downward and extends. The setting of the wind shield 504 plays the role of gathering heat and preventing the hot air flow from blowing toward the insertion port 101, so that the hot air flow can quickly move downward to reach the surface of the food.

[0051] In order to make the airflow blown out of the air outlet 400 of the air outlet channel 4 quickly reach the air guide cover 5, as shown in FIG. Figure 2 and Figure 4 As shown, the inner end of the air deflector 5 or the air inlet 500 of the air deflector is configured to be wide outside and narrow inside, so that the airflow blown out of the air outlet 400 can quickly enter the air deflector 5.

[0052] See again Figure 1 to Figure 4As shown, in this embodiment, the air fryer is a double-pot air fryer, specifically, there are two cooking chambers 100, which are sequentially distributed along the height direction of the inner pot 103; there are two frying baskets 2, and the two frying baskets 2 are respectively connected to the two cooking chambers 100 through the insertion port 101; similarly, there are two heating components 3, which are respectively arranged corresponding to the two cooking chambers 100, and each heating component 3 includes a fan component 301 located at the back of the cooking chamber 100 and an electric heating element 300 located at the top or above the cooking chamber 100. In the embodiment of the double-pot air fryer, the upper air guide 5 is connected to the top of the inner pot 103, and the lower air guide 5 is connected to the bottom of the middle transverse partition in the middle of the inner pot 103, and the lower air guide 5 divides the inner pot 103 into two upper and lower independent cooking chambers 100, so that the food in the two cooking chambers 100 will not have mixed flavors.

[0053] In other embodiments, the cooking cavities 100 may be three, four, etc., and distributed along the height direction of the fryer body 1; similarly, in other embodiments, the cooking cavities 100 may be distributed in sequence along the width direction of the fryer body 1, so that the fryer body 1 is a single-layer multi-cavity structure. That is, in other embodiments, the air fryer may also be a single-pot air fryer or a three-pot air fryer. As for the single-pot air fryer, it only has one cooking cavity 100, one frying basket 2, and one heating component 3; and the cooking cavity 100, frying basket 2, and heating component 3 corresponding to the three-pot air fryer may also be set to three, or the heating component 3 may be set to two, etc.

[0054] In some embodiments, Figure 1 and Figure 3 As shown, a groove 102 is provided on the outer side wall of the fryer body 1, and a control panel 6 that can move forward and backward can be rotatably connected in the groove 102. That is, the control panel 6 can be rotated and extended out of the groove 102 when in use, and can be retracted or folded into the groove 102 when not in use. This arrangement is convenient for users to operate at different use angles, and further saves space in the shell. When unfolded for use, it can be kept away from heat sources for convenient heat dissipation.
