Description

An air fryer / oven Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular to an air fryer / oven. Background Art

[0002] An air fryer is a kitchen appliance that uses high-temperature air to fry food. The resulting food is lower in fat than typical fried foods, making it a popular choice. The air fryer's heating element includes a motor, heating tubes, and a fan. During the cooking process, fumes and vapors generated by the air fryer enter the heating element and adhere to the heating tubes and fan surfaces. However, traditional heating elements are typically fixed to the air fryer's body and cannot be disassembled for cleaning. This leads to the accumulation of oil stains inside the heating element, ultimately causing the air fryer to produce an unpleasant odor and affecting people's dietary health.

[0003] In order to solve the problem of cleaning the air fryer, the Chinese patent with the announcement number CN214387234U discloses a detachable heating component for the air fryer. The heating component of this solution is detachably arranged on the machine cover by means of mutually cooperating fasteners and locks. At the same time, the power connector and the socket are used to connect the heating tube to the power supply, thereby realizing the rapid disassembly and assembly of the heating component and convenient cleaning of the inside of the heating component.

[0004] However, this solution has the following shortcomings: First, this solution sets the heating component on the cover, which not only makes the cover larger, but also when the heating component needs to be cleaned, the entire cover needs to be flipped up or removed, and then the heating component needs to be removed from the cover, so the operation is more cumbersome; second, this solution is equipped with a cooling fan for the motor, but after disassembly, the cooling fan is wrapped inside the cover, so the cooling fan cannot be cleaned, resulting in incomplete cleaning; third, the setting of the cover in this solution makes the structure of the air fryer more complicated, and also affects the overall aesthetics of the air fryer.

[0005] In addition to air fryers, ovens are also common kitchen appliances in our daily lives. Their working principle is to use the radiant heat emitted by electric heating elements to bake food. They can be used to make barbecue, bake bread and pastries, etc., and are also very popular among people. Existing ovens on the market usually include a box body, a baking cavity and a heating component. The heating component is installed in the baking cavity and is used to heat the baking cavity. In the process of cooking food, the generated oil smoke and water vapor will adhere to the heating component, so it needs to be cleaned regularly. However, the heating component of existing ovens is usually fixed in the baking cavity and cannot be disassembled for cleaning. Therefore, it will also cause more and more oil stains inside the heating component, which will eventually cause odor in the oven and affect people's dietary health. It can be seen that existing ovens also have the problem that the heating component cannot be disassembled and is difficult to clean, so there is an urgent need to propose a solution.

Specific embodiments

[0086] The specific embodiments of the present invention are described below with reference to the accompanying drawings. In order to fully understand the present invention, many details are described below, but for those skilled in the art, the present invention can be implemented without these details.

[0087] Figures 1 to 6 are related drawings of the first technical solution proposed by the present invention based on the overall inventive concept of a detachable heating component. The first technical solution involves a total of one embodiment (i.e., embodiment 1). The design details of this embodiment are introduced in detail below.

[0088] Example 1: Referring to Figures 1 and 2, an air fryer includes a body 4 and a heating assembly 5. Body 4 defines a cooking cavity 41 and a window 42 communicating with cooking cavity 41. Heating assembly 5 is removably mounted within window 42 for heating cooking cavity 41. The present invention provides window 42 on body 4 for mounting heating assembly 5. When cleaning is required, heating assembly 5 can be directly removed from window 42, making operation simple and convenient.

[0089] Referring to Figures 2, 5, and 6, the heating assembly 5 specifically comprises a heating tube 51, a soaking fan 52, and a fixed cover 53. The fixed cover 53 is removably mounted within the window 42, and the heating tube 51 and soaking fan 52 are located at the bottom of the fixed cover 53. The housing 4 houses a motor 43 that is connected to the soaking fan 52 and a connection assembly (not shown) electrically connected to the heating tube 51. The heating tube 51 heats the cooking cavity 41, while the soaking fan 52 improves heat transfer efficiency, evenly distributing heat from the heating tube 51 to all corners of the cooking cavity 41. The fixed cover 53 supports the heating tube 51 and soaking fan 52, making installation and removal of the heating assembly 5 easier. Preferably, in this embodiment, the fixed cover 53 is designed as a reflective disk with a heat radiation reflective layer on its surface. The reflective disk reflects heat from the heating tube 51 into the cooking cavity 41, thereby improving heating efficiency and ensuring uniform heating within the cooking cavity 41.

[0090] Referring to Figures 2 and 3, the housing 4 is also provided with a cooling fan 54 for dissipating heat from the motor 43. The cooling fan 54 is located at the top of the fixed cover 53, and the cooling fan 54 and the heat-scaling fan 52 are connected to the motor 43 via the same rotating shaft 541. Since the cooling fan 54 is located at the top of the fixed cover 53 and is coaxially connected to the heat-scaling fan 52, when the fixed cover 53 is removed, the cooling fan 54 is removed along with the heat-scaling fan 52 and the heating tube 51, allowing the cooling fan 54 to be cleaned. Due to the obstruction of the fixed cover 53, less oil and dirt enter the cooling fan 54, but oil and dirt will still accumulate after long-term use. Therefore, the cooling fan 54 and the heating assembly 5 are designed as a detachable integrated structure to facilitate more comprehensive and thorough cleaning of the oil and dirt.

[0091] Referring to Figures 2 to 6 , to prevent the blades from being exposed and deformed by stress, an upper protective cover 55 and a lower protective cover 56 are respectively provided above and below the fixed cover 53. Specifically, a first cavity for mounting the cooling fan 54 is provided between the upper protective cover 55 and the fixed cover 53, and a plurality of first hollow portions 551 are provided in the middle of the upper protective cover 55, which communicate with the first cavity. A second cavity for mounting the heating pipe 51 and the cooling fan 54 is provided between the lower protective cover 56 and the fixed cover 53, and a plurality of second hollow portions 561 are provided in the middle of the lower protective cover 56, which communicate with the second cavity. During cleaning, the cooling fan 54, the heat-saturating fan 52, and the heating pipe 51 can be cleaned through the first and second hollow portions 551, 561. The sidewalls of the upper protective cover 55 are provided with a plurality of heat dissipation holes 552, through which heat within the first cavity is discharged to the outside of the machine body 4, thereby preventing heat accumulation within the machine body 4 and effectively protecting the motor 43.

[0092] Referring to Figures 2 and 5 , the heating tube 51 is mounted on the fixed cover 53 via several L-shaped brackets 511 and positioned below the soaking fan 52. The connection assembly includes a mating socket and power connector. The socket is located within the cooking chamber 41, and the end of the heating tube 51 is provided with a power connector that extends outside the fixed cover 53. When the fixed cover 53 is installed within the window 42, the power connector at the end of the heating tube 51 plugs into the socket, completing the circuit.

[0093] Referring to Figures 1 to 3, the housing 4 has an independent mounting cavity 44 above the cooking cavity 41, equipped with an access cover 441 for sealing the mounting cavity 44. The motor 43 is mounted within the mounting cavity 44 via a mounting bracket, and the output shaft of the motor 43 is connected to the rotating shaft 541 via a clutch. Specifically, the clutch comprises an upper clutch 431 and a lower clutch 432, which engage with each other. The upper clutch 431 is located at the end of the output shaft of the motor 43, while the lower clutch 432 is located at the end of the rotating shaft 541. When the fixing cover 53 is installed in the window 42, the upper clutch 431 and the lower clutch 432 engage with each other, allowing the motor 43 to rotate and drive the heat-saturating fan 52 and the cooling fan 54. The access cover 441 allows the motor 43 to be lifted upwards whenever the heating assembly 5 is installed or removed, thereby more conveniently engaging or disengaging the upper and lower clutches 431 and 432. In other embodiments, the upper clutch 431 or the lower clutch 432 can also be set to a structure that can float up and down and automatically reset, or other installation methods can be adopted to ensure that the upper clutch 431 and the lower clutch 432 can automatically engage or disengage when installing or removing the heating component 5.

[0094] Referring to Figures 1, 2, and 4, preferably, the cooking cavity 41 opens toward the front of the housing 4, and the fryer assembly 6 is housed within the cooking cavity 41; the window 42 is located on the rear of the housing 4, thereby not affecting the exterior design of the front of the housing 4. Tracks 45 are provided on both sides of the interior of the housing 4, and an annular boss 554 is provided on the outer periphery of the upper protective cover 55, which cooperates with the track 45. The interlocking track 45 and annular boss 554 provide a guiding and limiting function, thereby facilitating the rapid installation of the fixed cover 53 into the window 42. It should be noted that in this embodiment, the window 42 is located on the rear of the housing 4, and the track 45 within the window 42 is a parallel track (i.e., the track extends along the width of the housing 4), thereby enabling the heating assembly to be installed by horizontal sliding. However, the scope of protection of the present invention is not limited to this. In other embodiments, the position of the window 42 can also be set at other positions such as the front side of the body 4 or the top of the body 4, and the heating component can also be installed by vertical sliding installation or inclined sliding installation. Those skilled in the art can make reasonable designs based on actual needs.

[0095] 1 and 2 , in order to facilitate the removal of the heating assembly 5 , the upper protective cover 55 is further provided with heat dissipation holes 553 on both sides of the heat dissipation hole 552 .

[0096] Figures 7 to 16 are relevant drawings of the second technical solution proposed by the present invention based on the overall inventive concept of a detachable heating component. The second technical solution involves a total of three embodiments (i.e., Embodiment 2 to Embodiment 4). The design details of these three embodiments are introduced in detail below.

[0097] Example 2: Referring to Figures 7 to 10, an air fryer includes a body 1, a lid 2, and a heating assembly 3. The body 1 is provided with a cooking cavity 11 and an installation window 12 connected to the cooking cavity 11. The heating assembly 3 is removably mounted within the installation window 12 for heating the cooking cavity 11. The lid 2 and the body 1 can be closed or separated to close or open the installation window 12. To clean the heating assembly 3, the lid 2 can be opened and removed from the installation window 12 for easy and convenient cleaning. Since the heating assembly 3 is located within the installation window 12, the lid 2 is compact and has a more compact and aesthetically pleasing design.

[0098] Referring to Figures 7 to 12 , the heating assembly 3 specifically includes a fixed cover 31, a heating tube 32 and a soaking fan 33 disposed at the bottom of the fixed cover 31; a connection assembly (not shown) electrically connected to the heating tube 32 is disposed within the mounting window 12; and a motor 21 and a transmission assembly for driving the soaking fan 33 are disposed within the cover 2. The heating tube 32 is used to heat the interior of the cooking cavity 11, and the soaking fan 33 improves heat transfer efficiency, evenly transferring heat from the heating tube 32 to all corners of the cooking cavity 11. The fixed cover 31 supports the heating tube 32 and the soaking fan 33, making installation and removal of the heating assembly 3 more convenient. Preferably, in this embodiment, the fixed cover 31 is designed as a reflective disk with a heat radiation reflective layer on its surface. The reflective disk reflects heat from the heating tube 32 into the cooking cavity 11, thereby further improving heating efficiency and ensuring uniform heating within the cooking cavity 11.

[0099] Referring to Figures 8 to 12 , the air fryer also features a cooling fan 34 for dissipating heat from the motor 21. This fan is mounted atop the fixed hood 31 and is connected to the transmission assembly via the same rotating shaft 35 as the soaking fan 33. Since the fan is mounted atop the fixed hood 31 and is coaxially connected to the soaking fan 33, when the fixed hood 31 is removed, the fan is removed along with the soaking fan 33 and the heating tube 32, allowing for cleaning. While the fan is shielded by the fixed hood 31, less oil and dirt enter the fan 34. However, this can still accumulate after prolonged use. Therefore, the fan 34 and the heating assembly 3 are designed as a detachable, integrated structure, facilitating more comprehensive and thorough cleaning of the oil.

[0100] Referring to Figures 8 to 12, to prevent the blades from being exposed and deformed by stress, a protective cover 36 is provided above the fixed cover 31. Specifically, a cavity for mounting the cooling fan 34 is provided between the protective cover 36 and the fixed cover 31, and the protective cover 36 is provided with a plurality of exhaust holes 361 and water outlet holes 362 connected to the cavity. During operation, the air from the cooling fan 34 is blown onto the cover 2 through the exhaust holes 361, thereby dissipating heat from the motor 21. The body 1 is provided with a plurality of heat dissipation holes 124 on the side of the heating component 3, which also helps to improve the heat dissipation effect. During cleaning, the cooling fan 34 is cleaned through the water outlet holes 362, and the cleaned water is discharged through the exhaust holes 361 and the water outlet holes 362 at the same time, thereby preventing moisture residue. In addition, the entire heating component 3 can be directly placed in a dishwasher for cleaning, thereby reducing the burden on people.

[0101] Referring to Figures 8 and 9 , the cover 2 includes a mounting cavity 20, within which the motor 21 is mounted and connected to the rotating shaft 35 via a transmission assembly. This design allows for concealed installation of the motor 21, thereby preventing safety hazards such as water intrusion during cleaning. To prevent heat from accumulating within the mounting cavity 20, several heat dissipation holes are provided on the sidewalls of the cover 2. Furthermore, to facilitate maintenance and inspection of the motor 21, this embodiment includes an access window on the top of the cover 2, along with an access cover 22 for sealing the access window.

[0102] 8 to 12 , in this embodiment, the connection assembly includes a socket and a power connector that cooperate with each other. The socket is arranged in the installation window 12, and the power connector is arranged at the end of the heating tube 32. The transmission assembly includes a first transmission assembly and a second transmission assembly that can be separated or connected to each other. The first transmission assembly is arranged on the output shaft of the motor, and the second transmission assembly is arranged on the rotating shaft 35. As a preferred embodiment, the first transmission assembly and the second transmission assembly are respectively a first clutch 23 and a second clutch 24 that cooperate with each other; the first clutch 23 is arranged on the output shaft of the motor 21, and the second clutch 24 is arranged on the rotating shaft 35. Therefore, when the heating assembly 3 is installed in the installation window 12, the heating tube 32 can be quickly connected to the power supply through the mutual connection of the socket and the power connector, and the heat-saturating fan 33 and the heat dissipating fan 34 can also be quickly connected to the motor 21 through the mutual engagement of the first clutch 23 and the second clutch 24, thereby achieving rapid docking of the heating assembly 3 with the cover 2, thereby improving the efficiency of disassembly and assembly.

[0103] 7 to 9 , a support portion is provided within the installation window 12, and the heating assembly 3 is placed above the support portion. As a preferred embodiment, the support portion is an annular boss 121 provided on the inner sidewall of the installation window 12, and the heating assembly 3 is placed above the annular boss 121. This design reduces unnecessary assembly and disassembly steps, thereby enabling quick removal and insertion of the heating assembly 3.

[0104] 7 to 10 , the connection methods between the cover 2 and the body 1 include, but are not limited to, a flip hinge, a snap-fit ​​connection, a screw-on connection, or a horizontal sliding connection. Specifically, a flip hinge means that the cover 2 is flippably mounted on the body 1 via a hinge, a snap-fit ​​connection means that the cover 2 is detachably mounted on the body 1 via a snap assembly, a screw-on connection means that the cover 2 is threaded or otherwise rotated to be mounted on the body 1, and a horizontal sliding connection means that the cover 2 is horizontally slidable to the body 1 via a slide rail assembly. The above connection methods all enable the cover 2 and the body 1 to be covered or separated from each other, thereby achieving the purpose of closing or opening the installation window 12. Therefore, in actual applications, a reasonable selection and design can be made based on specific needs. As a preferred embodiment, in this embodiment, the cover 2 is connected to the body 1 using a flip hinge. Specifically, one side of the cover 2 is vertically flippable mounted on the body 1 via a hinge, and the other side of the cover 2 is connected to the body 1 via a fastener (not shown in the figure).

[0105] Example 3: Referring to Figures 13 and 14, unlike Example 2, in this embodiment, the connection between the cover 2 and the body 1 is a screw-on connection. Specifically, the body 1 is provided with an annular step surface 122 on the inner side wall of the installation window 12, and a plurality of spaced-apart limiting bosses 123 are provided. The bottom edge of the cover 2 is provided with a plurality of limiting hooks 25. When closing the cover, the cover 2 is first rotated a certain angle so that the limiting hooks 25 and the limiting bosses 123 are offset from each other. The cover 2 is then placed on the annular step surface 122 and rotated a certain angle again so that the limiting hooks 25 and the limiting bosses 123 abut against each other, thereby achieving locking. To ensure that this connection method can be implemented smoothly, the structure of the limiting bosses 123 and the limiting hooks 25 should be reasonably designed in combination with the external structure of the cover 2 to prevent the cover 2 from being unable to rotate relative to the body 1. Of course, the cover 2 can also be directly designed as a circular structure that is easy to rotate around its central axis.

[0106] Example 4: Referring to Figures 15 and 16, the difference from Example 2 is that the connection between the machine cover 2 and the machine body 1 in this embodiment is a screw-on connection. Specifically, the machine body 1 is provided with a rotating shaft 13 extending in the vertical direction next to the installation window 12, and the side wall of the machine cover 2 is provided with a shaft sleeve 26 that cooperates with the rotating shaft 13. The machine cover 2 can be horizontally rotated around the rotating shaft 13 through the shaft sleeve 26, thereby opening or closing the installation window 12.

[0107] Referring to FIGS. 15 and 16, due to the different connection manners between the hood 2 and the body 1, the structure of the transmission assembly is correspondingly adjusted in this embodiment: The first transmission assembly and the second transmission assembly are respectively the first push rod 27 and the second push rod 28 that abut against each other. Specifically, the first push rod 27 has a linear structure and is vertically disposed on the output shaft of the motor 21, and the second push rod 28 has a U-shaped structure with an upward opening and is disposed at the end of the rotating shaft 35. When the hood 2 is closed, the first push rod 27 abuts against one of the side walls of the two side walls of the second push rod 28. When the motor 21 works, the first push rod 27 rotates along with the output shaft of the motor 21, thereby driving the second push rod 28 and the rotating shaft 35 to rotate, and thus driving the soaking fan 33 and the cooling fan 34 to rotate.

[0108] In addition to the two transmission assemblies described in Embodiment 2 and Embodiment 3, in other embodiments, other structures such as a magnetic attraction type can also be used to design the transmission assembly. For example: The first transmission assembly is a first magnetic attraction member, the second transmission assembly is a second magnetic attraction member, one of the first magnetic attraction member and the second magnetic attraction member is a magnet (or an electromagnet), and the other is a metal that can be attracted by the magnet (or the electromagnet), or both the first magnetic attraction member and the second magnetic attraction member are magnets (or electromagnets) that can attract each other. During operation, the polarity of the first magnetic attraction member is changed by the rotation of the motor to attract the second magnetic attraction member, thereby driving the rotating shaft 35 to rotate.

[0109] FIGS. 17 to 23 are related drawings of the third technical solution proposed based on the overall inventive concept of the detachable heating assembly of the present invention. The third technical solution involves a total of one embodiment (i.e., Embodiment 5). The design details of this embodiment are introduced in detail below.

[0110] Embodiment 5: Referring to FIGS. 17 to 20, an air fryer includes an upper pot body 7, a lower pot body 8, an upper heating assembly 9, and a cooking container. The upper pot body 7 and the lower pot body 8 are covered or separated from each other to form a cooking cavity with different cooking functions; the cooking container is installed in the cooking cavity for holding food ingredients; the upper heating assembly 9 is detachably disposed in the upper pot body 7 for heating the cooking cavity. Since the upper heating assembly 9 adopts an overall modular detachable design, when cleaning is required, the upper heating assembly 9 can be directly detached from the upper pot body 7, and the operation is simple and convenient.

[0111] Referring to Figures 18 to 21 , the upper heating assembly 9 specifically comprises a fixed cover 91, a heating tube 92, and a soaking fan 93. One side of the fixed cover 91 is removably attached to the upper pot body 7, while the other side of the fixed cover 91 is provided with the heating tube 92 and soaking fan 93. The upper pot body 7 is provided with a connection assembly (not shown) electrically connected to the heating tube 92, as well as a motor 71 and a transmission assembly for driving the soaking fan 93. The heating tube 92 is used to heat the cooking cavity, while the soaking fan 93 improves heat transfer efficiency, evenly distributing heat from the heating tube 92 to every corner of the cooking cavity. The fixed cover 91 supports the heating tube 92 and soaking fan 93, making installation and removal of the upper heating assembly 9 easier. Preferably, in this embodiment, the fixed cover 91 is designed as a reflective disk with a heat radiation reflective layer on its surface. The reflective disk reflects heat from the heating tube 92 into the cooking cavity, further improving heating efficiency and ensuring uniform heating within the cooking cavity.

[0112] Referring to Figures 18 to 21, more specifically, the connection assembly includes a socket and a power connector that cooperate with each other. The socket is disposed within the upper pot body 7, and the power connector is disposed at the end of the heating tube 92. The transmission assembly includes a rotating shaft 711 and a first transmission assembly and a second transmission assembly that can be separated or connected to each other. The soaking fan 93 is disposed on the fixed cover 91 via the rotating shaft 711. The first transmission assembly is disposed on the output shaft of the motor 71, and the second transmission assembly is disposed on the rotating shaft 711. As a preferred embodiment, the first transmission assembly and the second transmission assembly in this embodiment are respectively a first clutch 712 and a second clutch 713 that cooperate with each other. Therefore, when the upper heating assembly 9 is installed in the upper pot body 7, the heating tube 92 can be quickly connected to the power supply through the interconnection of the socket and the power connector. The soaking fan 93 can also be quickly connected to the motor 71 through the mutual engagement of the first clutch 712 and the second clutch 713. This allows for rapid docking of the upper heating assembly 9 with the upper pot body 7, thereby improving assembly and disassembly efficiency.

[0113] 18 to 21 , in other embodiments, the first transmission assembly and the second transmission assembly may also adopt a push rod design or a magnetic design. For example, when the push rod design is adopted, the first transmission assembly and the second transmission assembly are respectively a first push rod and a second push rod that can abut against each other. When the motor 71 is working, the first push rod rotates along with the output shaft of the motor, thereby driving the second push rod and the rotating shaft 711 to rotate, thereby driving the heat equalization fan 93 to rotate. When the magnetic design is adopted, the first transmission assembly and the second transmission assembly are respectively a first magnetic part and a second magnetic part that can be attracted to each other. One of the first magnetic part and the second magnetic part is a magnet (or electromagnet), and the other is a metal that can be attracted by a magnet (or electromagnet), or the first magnetic part and the second magnetic part are both magnets (or electromagnets) that can be attracted to each other. When working, the polarity of the first magnetic part changes through the rotation of the motor and is attracted to each other with the second magnetic part, thereby driving the heat equalization fan 93 to rotate.

[0114] Referring to Figures 18 to 21 , the air fryer also includes a protective cover 72 and a cooling fan 73. The protective cover 72 is positioned between the upper pot body 7 and the fixed cover 91. The cooling fan 73 is positioned between the upper pot body 7 and the protective cover 72 and is connected to the output shaft of the motor 71. The cooling fan 73 promptly dissipates heat from the motor 71, preventing it from overheating and potentially affecting its service life. In practice, the protective cover 72 can be designed to be either removable or non-removable, depending on the cleaning requirements of the cooling fan 73. As a preferred option, in this embodiment, the protective cover 72 is removably positioned between the upper pot body 7 and the fixed cover 91. Protected by the protective cover 72, the cooling fan 73 remains exposed after the upper heating assembly 9 is removed, thereby preventing the blades from being exposed and deformed by stress. Furthermore, due to the barrier effect of the protective cover 72, oil and dirt are largely prevented from entering the cooling fan 73. Therefore, the cooling fan 73 rarely requires cleaning. However, occasional cleaning or maintenance can be performed by removing the protective cover 72, resulting in a more user-friendly design.

[0115] 18 to 21 , the upper pot body 7 has a mounting cavity 70 , in which the motor 71 is mounted. A cooling fan 73 and a first clutch 712 are provided on the output shaft of the motor 71 . This design allows for concealed installation of the motor 71 , thereby preventing potential safety hazards such as water ingress into the motor 71 during cleaning. To prevent heat from accumulating within the mounting cavity 70 , the upper pot body 7 is provided with a plurality of exhaust holes (not shown in the figures). Furthermore, to facilitate maintenance and inspection of the motor 71 , an inspection window is provided at the top of the upper pot body 7 in this embodiment, along with an inspection cover 74 for sealing the inspection window.

[0116] Referring to Figures 18 to 20, as a specific installation method, a knob 75 with a limiting boss is provided on both sides of the upper pot body 7, and both the protective cover 72 and the fixed cover 91 are provided with a strip-shaped notch 721 that matches the knob 75. Rotating the knob 75 until it is aligned with the strip-shaped notch 721 unlocks the protective cover 72 and the fixed cover 91, thereby removing them from the limiting boss; rotating the knob 75 until it is offset from the strip-shaped notch 721 locks the protective cover 72 and the fixed cover 91 to the limiting boss.

[0117] Referring to Figure 18 , the air fryer also includes a grease trap 77, which is removably mounted on the upper pot body 7 and located below the upper heating assembly 9. This trap 77 serves as a barrier to oil and dirt, reducing the amount of oil contamination on the upper heating assembly 9 and thus simplifying the frequency and difficulty of cleaning the upper heating assembly 9. When cleaning is necessary, the trap 77 and the entire upper heating assembly 9 can be placed in a dishwasher for cleaning, reducing the burden on the user.

[0118] Referring to Figures 18, 19, and 23, the lower pot body 8 is removably provided with a lower grilling tray 81 with a lower heating assembly 811 at its bottom. When the upper pot body 7 and lower pot body 8 are covered, the upper heating assembly 9 alone cooks the cooking cavity, or the upper heating assembly 9 and lower heating assembly 811 work together to cook the cooking cavity. When the upper pot body 7 and lower pot body 8 are separated, the lower heating assembly 811 alone cooks the cooking cavity. Preferably, the lower heating assembly 811 also utilizes a heating tube. Specifically, when the upper pot body 7 and lower pot body 8 are covered, an air frying cavity is formed between them. In this case, the upper heating assembly 9 can heat the air frying cavity alone, or the lower heating assembly 811 can be activated simultaneously. Furthermore, a cooking cavity with functions other than frying, grilling, steaming, or other functions can be formed between the upper pot body 7 and lower pot body 8. In this case, the lower heating assembly 811 can heat the cooking cavity alone, or the upper heating assembly 9 can be activated simultaneously. When the upper pot body 7 and the lower pot body 8 are separated from each other, the lower pot body 8 can also independently form a cooking cavity with functions such as frying, steaming, or other functions in addition to air frying. In this case, the upper heating component 9 is not in operation, and the lower heating component 811 heats the cooking cavity alone. As can be seen, the air fryer provided by this embodiment can be combined and set to different cooking functions according to the state of the upper pot body 7 and the lower pot body 8 being covered or separated. Corresponding control programs can be set according to different cooking functions, thereby realizing the use of the upper heating component 9 and the lower heating component 811 separately or in combination, thereby achieving multiple uses of one machine and meeting the diverse needs of customers.

[0119] Referring to Figures 18, 19, and 23, the cooking container is a fryer basket 82 or an upper grilling tray 76. The fryer basket 82 is placed above the lower grilling tray 81, and the upper grilling tray 76 is removably attached to the upper pot body 7 and positioned below the upper heating assembly 9. Specifically, when the cooking chamber is used as an air frying chamber or a steaming chamber, the fryer basket 82 can be used as the cooking container, and other components such as a grill 83 can be placed in the fryer basket 82. When the cooking chamber is used as a grilling chamber, the fryer basket 82 can be removed and the upper grilling tray 76 can be installed. The upper grilling tray 76 and the lower grilling tray 81 cooperate to form a grilling chamber, thereby achieving the grilling effect of the grilling device. Of course, in addition to the two cooking containers and usage methods described in this embodiment, other cooking containers can be selected and used individually or in combination according to the cooking function, thereby expanding the multifunctionality of the air fryer.

[0120] Referring to Figures 19 and 23 , the connection methods between the upper pot body 7 and the lower pot body 8 include, but are not limited to, a flip hinge, a snap-fit ​​connection, a screw-on connection, a horizontal sliding connection, or a vertical lift connection. Specifically, a flip hinge means that the upper pot body 7 is flippably attached to the lower pot body 8 via a hinge; a snap-fit ​​connection means that the upper pot body 7 is detachably attached to the lower pot body 8 via a snap assembly; a screw-on connection means that the upper pot body 7 is attached to the lower pot body 8 using a threaded connection or other rotational method; a horizontal sliding connection means that the upper pot body 7 is horizontally slidable on the lower pot body 8 via a slide rail assembly; and a vertical lift connection means that the upper pot body 71 is vertically liftable on the lower pot body 8 via a lifting mechanism. All of the above connection methods can achieve the mutual covering or separation of the upper pot body 7 and the lower pot body 8. Therefore, in actual applications, they can be reasonably selected and designed according to specific needs. As a preferred embodiment, in this embodiment, the upper pot body 7 is flippably attached to the lower pot body 8 via a hinge.

[0121] Figures 24 to 27 are relevant drawings of the fourth technical solution proposed by the present invention based on the overall inventive concept of a detachable heating component. The fourth technical solution involves a total of one embodiment (i.e., embodiment six). The design details of this embodiment are introduced in detail below.

[0122] Example 6: Referring to Figures 24 and 25, an oven with a removable heating assembly includes a housing 100, a door 101, and a heating assembly. The housing 100 is provided with a baking cavity 102 and a door 101 for enclosing the baking cavity 102. The housing 100 is provided with a window 103 communicating with the baking cavity 102. The heating assembly includes a heating assembly 200, which is removably disposed within the window 103 for heating the baking cavity 102. The present invention provides a window 103 on the housing 100 for mounting the heating assembly 200. When cleaning is required, the heating assembly 200 can be directly removed from the window 103, making operation simple and convenient.

[0123] Referring to Figures 25 to 27 , the heating assembly 200 specifically includes an upper heating tube 201, a soaking fan 203, and a fixed cover 204. The fixed cover 204 is removably mounted within the window 103, and the upper heating tube 201 and soaking fan 203 are located at the bottom of the fixed cover 204. A connecting assembly (not shown) electrically connected to the upper heating tube 201 is located within the window 103, along with a motor 106 and a transmission assembly that are electrically connected to the soaking fan 203. The upper heating tube 201 is used to heat the interior of the baking chamber 102, and the soaking fan 203 improves heat transfer efficiency, evenly distributing heat from the upper heating tube 201 to every corner of the baking chamber 102. The fixed cover 204 supports the upper heating tube 201 and soaking fan 203, making installation and removal of the heating assembly 200 more convenient. Preferably, in this embodiment, the fixed cover 204 is designed as a reflective disk with a heat radiation reflective layer on the surface. The reflective disk can reflect the heat of the upper heating tube 201 into the baking cavity 102, thereby improving the heating efficiency and ensuring uniform heating in the baking cavity 102.

[0124] 25 and 26 , the oven further includes a protective cover 207 and a cooling fan 205 . The cooling fan 205 is used to dissipate heat from the motor 106 , and the protective cover 207 is used to prevent the blades of the cooling fan 205 from being exposed and deformed by stress. In actual application, the installation methods of the protective cover 207 and the cooling fan 205 include the following two methods: the first is to design the protective cover 207 and the cooling fan 205 as one with the heating component 200, so as to facilitate disassembly and cleaning, that is, the protective cover 207 is arranged above the fixed cover 204, and the cooling fan 205 is arranged between the protective cover 207 and the fixed cover 204, and is connected to the rotating shaft 206 of the heat-averaging fan 203; the second is to set the protective cover 207 and the cooling fan 205 at the bottom of the motor 106, instead of designing them as one with the heating component 200, thereby fully streamlining the structure of the heating component 200, that is, the protective cover 207 is arranged at the bottom of the motor 106, and the cooling fan 205 is arranged between the motor 106 and the fixed cover 204, and is connected to the output shaft of the motor 106.

[0125] 25 and 26 , the first installation method is preferably used in this embodiment to set the protective cover 207 and the cooling fan 205. Specifically, the cooling fan 205 is arranged on the top of the fixed cover 204, and the cooling fan 205 and the heat-averaging fan 203 are connected to the transmission assembly via the same rotating shaft 206. Since the cooling fan 205 is arranged on the top of the fixed cover 204 and is coaxially connected to the heat-averaging fan 203, when the fixed cover 204 is removed, the cooling fan 205 will be removed along with the heat-averaging fan 203 and the upper heating tube 201, so that the cooling fan 205 can be cleaned. Due to the obstruction of the fixed cover 204, less oil and dirt enter the cooling fan 205, but after long-term use, there will still be oil and dirt accumulation. Therefore, the cooling fan 205 and the heating assembly 200 are designed as an integrated detachable structure, which helps to clean the oil and dirt more comprehensively and thoroughly. A protective cover 207 is located above the fixed cover 204. A cavity for mounting the cooling fan 205 is defined between the protective cover 207 and the fixed cover 204. The protective cover 207 also features several hollow sections 208 and heat dissipation holes 209 in the middle, connecting to the cavity. The heat dissipation holes 209 allow access to the cooling fan 205 within the cavity during cleaning. The sidewalls of the protective cover 207 are provided with several heat dissipation holes 209, which allow heat within the cavity to be discharged outside the housing 100. This prevents heat accumulation within the housing 100 and effectively protects the motor 106. To facilitate removal of the heating assembly 200, the protective cover 207 also features recessed openings 210 on either side of the heat dissipation holes 209.

[0126] Referring to Figures 25 and 27 , the upper heating tube 201 is mounted on the bottom of the fixed cover 204 via several connecting brackets 202, located below the soaking fan 203. The connecting assembly includes a mating socket and power connector. The socket is located within the baking chamber 102, and the end of the upper heating tube 201 is equipped with a power connector that extends outside the protective cover 207. When the heating assembly 200 is installed in the window 103, the power connector at the end of the upper heating tube 201 plugs into the socket, completing the circuit.

[0127] Referring to Figures 24 to 27 , a mounting slot 109 is provided at the top of the housing 100, connected to the window 103. The motor 106 is detachably mounted in the mounting slot 109 via a mounting bracket 110 and is connected to the rotating shaft 206 via a transmission assembly. The transmission assembly includes a first transmission assembly and a second transmission assembly, which can be separated or connected to each other. The first transmission assembly is mounted on the output shaft of the motor 106, and the second transmission assembly is mounted on the rotating shaft 206. As a preferred embodiment, the first transmission assembly and the second transmission assembly respectively comprise a first clutch 107 and a second clutch 108, which cooperate with each other. The first clutch 107 is mounted on the output shaft of the motor 106, and the second clutch 108 is mounted on the rotating shaft 206. Therefore, when the heating assembly 200 is installed in the window 103, the motor 106 can be lifted upward via the mounting bracket 110, causing the first clutch 107 and the second clutch 108 to engage with each other, thereby achieving rapid docking and improving assembly and disassembly efficiency.

[0128] Referring to Figure 27 , the oven also includes a support cover 212 fixed to the bottom of the mounting slot 109. The bottom of the mounting bracket 110 is provided with a plurality of positioning posts 111. The support cover 212 is provided with positioning holes for inserting the positioning posts 111. The mutual cooperation between the positioning posts 111 and the positioning holes can play a positioning and guiding role, ensuring that the motor 106 is accurately installed in the mounting slot 109, thereby ensuring that the first clutch 107 and the second clutch 108 are accurately and securely connected. To ensure that the cooling fan 205 effectively dissipates heat on the motor 106, the support cover 212 also has a hollow portion connected to the cavity. Therefore, the airflow generated by the cooling fan 205 in the cavity can flow to the motor 106 through the hollow portion of the protective cover 207 and the support cover 212, thereby dissipating heat from the motor. In addition, the support cover 212 also serves to shield the motor 106 and the mounting bracket 110, preventing the user from seeing the internal components through the window 103 and affecting the visual effect.

[0129] 27 , in order to further improve the connection stability of the first clutch 107 and the second clutch 108, elastic buckles 112 are provided on both sides of the mounting bracket 110, and the support cover 212 is provided with hooks 213 that cooperate with the elastic buckles 112.
