Description

Technical Field

[0001] This application relates to the field of kitchen appliance technology, specifically an air fryer. Background Technology

[0002] An air fryer is a cooking device that rapidly heats airflow using heating elements and then uses a high-powered fan to bring that heated airflow into contact with the food, achieving a frying effect. Because the food it produces tastes good, contains less oil, and has fewer harmful substances, it is very popular. Therefore, it has gradually been accepted by ordinary families and has brought convenience to people's lives.

[0003] Air fryers, a related technology, come in single-pot and double-pot versions. Single-pot air fryers have one set of hot air components, while double-pot air fryers, especially those with two layers, generally have two sets of hot air components. Each set of hot air components includes an electric heating element and a fan assembly. The electric heating element is generally an electric heating wire or an electric heating tube, and the fan assembly blows the heat generated by the electric heating element into the inner pot or food cooking cavity to bake the food.

[0004] In related technologies, single-pot air fryers typically have their hot air assembly positioned above the cooking chamber or at the top of the product. For example, Chinese patent application CN221330985U, entitled "Hot Air Assembly and Air Fryer of an Air Fryer," includes a guide vane, a vertically mounted motor, a cooling fan, and a heating fan above the cooking chamber. The cooling and heating fans are sequentially mounted axially on the vertical shaft of the motor, with the heating fan located below the guide vane to direct hot airflow towards the cooking chamber. The cooling fan is located above the guide vane to dissipate heat from the motor. Double-pot air fryers, to maximize the cooking chamber space, generally have their hot air assembly positioned at the back of the air fryer or on the side furthest from the user. They also include a guide vane, a motor, a cooling fan, and a heating fan. The motor shaft is horizontally positioned, with the cooling and heating fans sequentially connected axially to the motor shaft. The cooling and heating fans are located on opposite sides of the guide vane, as in the earlier application CN119055104A, entitled "Air Fryer."

[0005] The air fryer technology has the following defects in actual production and use: the cold fan and hot fan of the fan assembly are respectively mounted axially on the motor shaft on one side of the motor, and the electric heating element is set on the outside of the hot fan. This makes the overall thickness of the hot air assembly relatively thick, resulting in a relatively high overall height of the air fryer, which makes it impossible to place it within the height limit of the cabinet; while for double-pot air fryers, the fan assembly is set on the back of the air fryer, resulting in a longer length of air fryer. When placed in a cabinet, it will protrude outwards from the cabinet, affecting the safety of use. Summary of the Invention

[0006] The technical problem to be solved by this application is to overcome the defects of the above-mentioned related technologies and provide an air fryer with a compact structure, thin thickness and small volume of hot air assembly.

[0007] The technical solution of this application is to provide an air fryer having the following structure: including...

[0008] The fryer body has at least one cooking cavity and an insertion port connected to the cooking cavity and allowing a frying basket to be inserted into or detached from the cooking cavity. Each cooking cavity is provided with an air guide plate above it, and an installation cavity is provided above the air guide plate.

[0009] At least one hot air assembly is disposed above the cooking cavity. Each hot air assembly includes a motor, an electric heating element, a first fan, and a second fan. The electric heating element is connected below the air guide plate. The motor is connected within the mounting cavity, and the motor's shaft forms a first connection end at its lower end and a second connection end at its upper end. The first connection end passes downward through the air guide plate and connects to the first fan below the air guide plate. The second connection end connects to the second fan within the mounting cavity.

[0010] The first fan has a recessed cavity along the axial direction at its center for the lower end of the motor to be inserted into, and the lower end of the motor is inserted into the first recessed cavity; and / or the second fan has a recessed cavity along the axial direction at its center for the upper end of the motor to be inserted into, and the upper end of the motor is inserted into the second recessed cavity.

[0011] In some embodiments, the first cavity has a columnar first protrusion formed below the first fan, and the horizontal projection of the fan blades of the first fan is located on the outer wall of the first protrusion; and / or

[0012] The second cavity has a columnar second protrusion formed above the second fan, and the horizontal projection of the fan blades of the second fan is located on the outer wall of the second protrusion.

[0013] In some embodiments, the lower edge of the fan blades of the first fan, projected horizontally onto the first protrusion, is higher than the bottom end face of the first protrusion; and / or

[0014] The upper edge of the blades of the second fan projected horizontally onto the second protrusion is lower than the top end face of the second protrusion.

[0015] In some embodiments, the bottom center of the air guide plate is provided with an upwardly recessed guide groove, the first fan and the electric heating element are both disposed in the guide groove, and the electric heating element is disposed along the circumference of the first fan on the outer edge of the first fan.

[0016] In some embodiments, the projection of the electric heating element in the horizontal direction is located on the outer wall of the first fan.

[0017] In some embodiments, there are two cooking cavities, which are distributed sequentially along the height of the fryer body; there are two hot air assemblies, which are respectively connected to the top of the two cooking cavities.

[0018] In some embodiments, the top of the fryer body is provided with a recessed receiving groove on the side near the user, and a control panel that can extend or retract into the receiving groove is rotatably connected therein.

[0019] In some embodiments, the side of the control panel closest to the user is rotatably connected to the inner wall of the receiving groove, and the control panel is provided with a positioning tooth group arranged circumferentially around the rotation axis of the control panel, and a positioning member that is elastically engaged with the positioning tooth group is connected inside the receiving groove.

[0020] In some embodiments, the inner wall of the receiving groove is provided with a plurality of heat dissipation windows that communicate with the mounting cavity.

[0021] In some embodiments, the top of the fryer body is provided with a recess that communicates with the receiving groove and allows for the insertion of a finger.

[0022] In summary, compared with related technologies, the air fryer of this application has the following advantages: the hot air assembly of the air fryer is located above the cooking chamber, and the center of the first fan of the hot air assembly has a first recess along the axial direction into which the lower end of the motor is inserted; and / or the center of the second fan has a second recess along the axial direction into which the upper end of the motor is inserted. This arrangement allows the first and second fans to be connected to or located at the two ends of the motor, respectively, and the first and / or second fans to wrap around the outside of the motor. This reduces the overall height of the first fan, second fan, and motor after assembly, making the structure of the hot air assembly more compact, thinner, and smaller in size. Therefore, the overall height of the air fryer can be reduced while keeping the height of the cooking chamber unchanged, thus adapting to the height limit of the cabinet and meeting user needs. Furthermore, since the hot air assembly of the air fryer is located above the cooking chamber, the length of the double-pot air fryer will not increase due to the setting of the hot air assembly, thus adapting to the depth limit of the cabinet.

[0039] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0040] In the description of the embodiments of the application, it should be understood that the terms "lateral", "longitudinal", "width", "thickness", "upper", "lower", "front", "rear", "vertical", "top", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0041] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more, unless otherwise expressly defined.

[0042] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "fixation," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; or they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0043] See Figures 1 to 14As shown in the figure, this application discloses an air fryer, the structure of which includes an air fryer body 1 and an air fryer basket 2. The air fryer body 1 includes an outer shell, an electronic control unit connected to the outer shell, a control panel 5, and an inner liner connected to the outer shell. The air fryer body 1 has at least one cooking cavity 100, which is formed in the space defined by the inner liner. The user side of the air fryer body 1 is provided with an insertion port 101 that communicates with the cooking cavity 100 and allows the air fryer basket 2 to be inserted into or removed from the cooking cavity 100. The number of insertion ports 101 is adapted to the number of cooking cavities 100. At least one hot air assembly corresponding to the cooking cavity 100 is connected inside the air fryer body 1, that is, one cooking cavity 100 corresponds to one hot air assembly.

[0044] See Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the air fryer in this embodiment has two cooking chambers 100, which are distributed sequentially along the height of the fryer body 1; there are two hot air assemblies, which are respectively connected to the top of the two cooking chambers 100. That is, in this embodiment, the air fryer is a double-pot air fryer with upper and lower layers. The hot air assembly located in the middle divides the inner liner inside the outer shell into two cooking chambers 100, which are independent. That is, the hot air assembly above the upper cooking chamber 100 bakes the food in the upper cooking chamber 100, and the hot air assembly above the lower cooking chamber 100 bakes the food in the lower cooking chamber 100.

[0045] In other embodiments, the cooking cavities may be three, four, or so, and distributed along the height of the fryer body; similarly, in other embodiments, the air fryer may be a single-pot air fryer or a three-pot air fryer. As for the single-pot air fryer, it has only one cooking cavity, one frying basket, and one hot air assembly, etc.; while the cooking cavity, frying basket, and hot air assembly of the three-pot air fryer may all be set to three.

[0046] In this embodiment, each cooking cavity 100 has an air guide plate 102 above it, and an installation cavity 103 is provided above the air guide plate 102. The installation cavity 103 is connected to the heat dissipation hole 104 on the outer casing. See also Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the hot air assembly is located above the cooking cavity 100. Each hot air assembly includes an electric heating element 4 and a fan assembly 3. The electric heating element 4 is an electric heating tube or an electric heating wire. The electric heating element 4 is connected to the air guide plate 102 and located below the air guide plate 102. When the airflow passes through the electric heating element 4, the airflow is heated to generate hot airflow for baking ingredients. The fan assembly 3 includes a motor 300, a first fan 301, and a second fan 302. The motor 300 is connected inside the mounting cavity 103. The shaft of the motor 300 is vertically arranged, and a first connecting end 307 is formed at the lower end of the motor 300 and a second connecting end 308 is formed at the upper end of the motor 300. The first connecting end 307 passes downward through the air guide plate 102 and is connected to the first fan 301 below the air guide plate 102. The second connecting end 308 is connected to the second fan 302 inside the mounting cavity 103. The first fan 301 is used to diffuse the hot air generated by the electric heating element 4 into the cooking cavity 100 to bake the food. Therefore, the first fan 301 is also called a hot fan. The second fan 302 is used to diffuse the heat generated by the motor 300 through the heat dissipation holes 104 on the back of the outer casing. Therefore, the second fan 302 is also called a cold fan or a cooling fan. When the shaft of the motor 300 rotates, the first fan 301 and the second fan 302 rotate and work simultaneously.

[0047] It is understandable that the hot air assembly is positioned above or on top of the cooking cavity 100, and the thickness of the hot air assembly directly affects the overall height of the air fryer. That is, with the height of the cooking cavity 100 remaining constant, a thicker hot air assembly results in a taller overall air fryer, and a thinner hot air assembly results in a shorter overall height. The thickness of the hot air assembly is the sum of the heights of the motor 300, the first fan 301, the second fan 302, the air guide plate 102, the electric heating element 4, and the mounting cavity 103, all distributed along the axial direction of the motor 300.

[0048] It is easy to understand that the height of the fan assembly 3 in the hot air assembly directly affects the thickness of the hot air assembly, especially in a double-layered air fryer with two fan assemblies 3 along the height direction of the air fryer. Therefore, in this embodiment, in order to reduce the thickness of the hot air assembly, the overall height of the fan assembly 3 is reduced. Specifically, see [link to documentation]. Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11As shown, a first recess 303 is provided axially at the center of the first fan 301, into which the lower end of the motor 300 is inserted; and / or a second recess 305 is provided axially at the center of the second fan 302, into which the upper end of the motor 300 is inserted; that is, in this embodiment, a recess into which the end of the motor 300 is inserted can be provided at the center of the first fan 301, or at the center of the second fan 302, or recesses into which both ends of the motor 300 are respectively provided at the centers of the first fan 301 and the second fan 302.

[0049] Specifically in this embodiment, see Figure 4 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, the first fan 301 and the second fan 302 are respectively provided with the first cavity 303 and the second cavity 305 into which the motor 300 is inserted, thus making the overall height of the fan assembly 3 smaller. Understandably, compared to assembling the fans sequentially along the axial direction on one side of the motor 300 shaft, where the overall height of the fan assembly 3 is the sum of the three components, in this embodiment, the first fan 301 and the second fan 302 are respectively connected to the two ends of the motor 300 or located at the two ends of the motor 300, with the end of the motor 300 inserted into the recess in the center of the fan, or the first fan 301 and / or the second fan 302 wrapping around the outside of the motor 300. This reduces the overall height of the first fan 301, the second fan 302, and the motor 300 after assembly, making the structure of the hot air assembly more compact, thinner, and smaller in volume. Therefore, the overall height of the air fryer can be reduced while keeping the height of the cooking chamber 100 unchanged, thus adapting to the height limit of the cabinet and meeting user needs. Furthermore, since the hot air assembly of the air fryer is located above the cooking chamber 100, the length of the double-pot air fryer will not increase due to the setting of the hot air assembly, thus adapting to the depth limit of the cabinet.

[0050] Further in this embodiment, see Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11As shown, a columnar first protrusion 304 is formed in the first cavity 303 below the first fan 301, and the horizontal projection of the fan blades of the first fan 301 is located on the outer wall of the first protrusion 304; and a columnar second protrusion 306 is formed in the second cavity 305 above the second fan 302, and the horizontal projection of the fan blades of the second fan 302 is located on the outer wall of the second protrusion 306. In other words, the first protrusion 304 protrudes downward along the axial direction of the first fan 301, so that the fan blades of the first fan 301 are located at the upper end of the first protrusion 304, and the height of the first protrusion 304 is greater than or equal to the height of the fan blades of the first fan 301; the second protrusion 306 protrudes upward along the axial direction of the second fan 302, so that the fan blades of the second fan 302 are located at the lower end of the second protrusion 306, and the height of the second protrusion 306 is equal to or greater than the height of the fan blades of the second fan 302. In this embodiment, the upper and lower ends of the first protrusion 304 and the second protrusion 306 are positioned at the same orientation as shown in the accompanying drawings or when the air fryer is in use. This arrangement positions the blades of the first fan 301 and the second fan 302 closer to the center of the motor 300, thereby reducing the overall height of the fan assembly 3.

[0051] In a preferred embodiment of this example, see Figure 9 , Figure 10 and Figure 11 As shown, the lower edge of the blades of the first fan 301 projected horizontally onto the first protrusion 304 is higher than the bottom end face of the first protrusion 304; the upper edge of the blades of the second fan 302 projected horizontally onto the second protrusion 306 is lower than the top end face of the second protrusion 306. Specifically, the lower edge of the blades of the first fan 301 projected horizontally onto the first protrusion 304 is higher than the bottom end face of the first protrusion 304, meaning the height of the first protrusion 304 is greater than the height of the blades of the first fan 301, making the blades of the first fan 301 closer to the center of the motor 300; similarly, the blades of the second fan 302 are also closer to the center of the motor 300. This arrangement not only provides ample space for the installation of the electric heating element 4, but also reduces the combined thickness of the first fan 301 and the electric heating element 4 after installation, further reducing the thickness of the hot air assembly. In addition, the blades of the second fan 302 are closer to the center of the motor 300, which reduces the overall height of the mounting cavity 103, thereby making the overall height of the air fryer lower.

[0052] In the above embodiments, it can be understood that the two ends of the motor 300 shaft extend axially from the end faces of the motor 300, thereby forming a first connecting end 307 for connecting the first fan 301 and a second connecting end 308 for connecting the second fan 302. The fan is integrally stamped from a metal plate, and the end of the motor 300 is inserted into the cavity within the protrusion. The fan blades are connected to one end of the protrusion. Therefore, when the fan is installed on the shaft of the motor 300, when the end of the fan is inserted into the cavity of the protrusion, the protrusion wraps around the outside of the motor 300, and the fan blades at one end of the protrusion are located at a more central position on the motor 300, or the horizontal projection of the fan blades falls entirely on the outer wall of the motor 300.

[0053] In this embodiment, to further reduce the overall thickness of the hot air assembly, see [reference needed]. Figure 8 and Figure 11 As shown, the bottom center of the air guide plate 102 has an upwardly recessed guide groove 107. The first fan 301 and the electric heating element 4 are both disposed within the guide groove 107, and the electric heating element 4 is disposed along the circumference of the first fan 301 on its outer edge. This arrangement avoids the superposition of the axial thickness of the electric heating element 4 and the first fan 301. That is, in this embodiment, the electric heating element 4 is disposed within the guide groove 107 of the air guide plate 102 and located outside the first protrusion 304 of the first fan 301. Therefore, the overall thickness of the hot air assembly can be further reduced, thus lowering the overall height of the air fryer.

[0054] Furthermore, in the above embodiment, the projection of the electric heating element 4 in the horizontal direction is located on the outer wall of the first fan 301, that is, the bottom height of the electric heating element 4 is higher than or equal to the height of the lower end of the first protrusion 304. This arrangement can further reduce the axial thickness of the electric heating element 4 and the first fan 301.

[0055] In the above embodiments, the motor of the fan assembly is an AC motor, and see [link to previous section]. Figure 12 and Figure 13 As shown, the motor of the fan assembly can also be a DC motor.

[0056] In some embodiments, see Figure 1 , Figure 2 and Figure 14As shown, the top of the air fryer body 1, near the user, has a recessed receiving groove 105. A control panel 5, which can extend or retract, is rotatably connected within the receiving groove 105. This control panel 5 is electrically connected to the electronic control unit inside the air fryer and is used to control the operation of the air fryer. The user simply needs to stand in front of the air fryer and rotate the control panel 5 to a suitable tilt angle so that the operating interface of the control panel 5 is directly facing the user's eyes, avoiding bending over or looking down to operate. Therefore, this air fryer makes the control panel 5 simple and convenient to operate, providing a good user experience. Furthermore, the control panel 5 can be retracted into the receiving groove 105 at the top of the air fryer body 1, facilitating packaging and transportation and preventing damage.

[0057] In the above embodiment, the side of the control panel 5 closest to the user is rotatably connected to the inner wall of the receiving groove 105 via a rotating shaft 500. The control panel 5 is provided with a positioning gear assembly 501 circumferentially arranged around the rotating shaft 500 of the control panel 5, and a positioning element that elastically engages with the positioning gear assembly 501 is connected within the receiving groove 105. This positioning element can be an arc-shaped protrusion integrally formed within the receiving groove 105, or it can be an elastic pin installed within the receiving groove 105. Thus, when the control panel 5 rotates, the elastic engagement between the positioning element and the positioning gear assembly 501 allows the control panel 5 to maintain a constant angle after rotation.

[0058] In some embodiments, see Figure 2 As shown, the inner wall of the receiving groove 105 is provided with multiple heat dissipation windows 106 that communicate with the mounting cavity 103. When the control panel 5 is rotated out of the receiving groove 105, the heat dissipation windows 106 can be opened, which can accelerate the heat dissipation of the motor 300 in the air fryer mounting cavity 103, and the heat of the motor 300 in the mounting cavity 103 will not affect the control panel 5.

[0059] In some embodiments, to facilitate the rotation of the control panel 5 out of the receiving slot 105, see [reference needed]. Figure 2 As shown, a recess 108 is provided on the top of the fryer body 1, which is connected to the receiving groove 105 and allows fingers to be inserted. When rotating the control panel 5, the control panel 5 can be easily rotated out of the receiving groove 105 by inserting a finger into the recess 108, making the operation simple, convenient and labor-saving.
