[0026] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0027] Hereinafter, an air fryer 100 according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0028] like Figure 1-Figure 4 As shown, the air fryer 100 according to the embodiment of the present invention includes: a casing 1, a heating plate 2, a cooking fan 3 and a driving member 4, the casing 1 is formed with a cooking cavity 11; the heating plate 2 is installed in the casing 1; the cooking fan 3 is rotatably installed in the casing 1, and is used to drive the airflow at the heating plate 2 to flow toward the cooking cavity 11; one of the driving member 4 and the cooking fan 3 is connected to a first coupling member 5 and the other is connected to a second coupling member 6, the first coupling member 5 and the second coupling member 6 are detachably connected, and the driving member 4 is used to drive the cooking fan 3 to rotate.

[0029] As a result, the cooking fan 3 is easy to clean, which reduces the difficulty of cleaning the air fryer 100, is beneficial to improving the cleanliness of the air fryer 100, and improves user satisfaction.

[0030] For example, refer to Figure 1-Figure 2As shown, the air fryer 100 includes a housing 1, the housing 1 is formed with a cooking cavity 11, the top of the housing 1 is formed with an opening of the cooking cavity 11, a pot cover 7 is detachably mounted on the top of the housing 1 to selectively close the opening of the cooking cavity 11, a frying basket is mounted in the cooking cavity 11, and the frying basket is used to hold fried food. A heating plate 2 is detachably mounted at the bottom of the cooking cavity 11, a mounting cavity is formed on the side of the heating plate 2 facing away from the cooking cavity 11, a cooking fan 3 is mounted in the mounting cavity, and the cooking fan 3 is arranged to be rotatable relative to the housing 1.

[0031] At the same time, a vertically penetrating air inlet hole can be provided in the middle part of the heating plate 2, and a vertically penetrating air outlet hole can be defined at the edge of the heating plate 2. When the cooking fan 3 rotates, the airflow in the cooking cavity 11 can be drawn into the installation cavity through the air inlet hole, the airflow can flow through the heating plate 2 and be heated, and the cooking fan 3 can drive the airflow heated by the heating plate 2 toward the outside, so that the airflow can flow upward into the cooking cavity 11 through the air outlet hole, so that the airflow can circulate between the cooking cavity 11 and the installation cavity, and the airflow will flow through the frying basket to heat the fried food in the frying basket.

[0032] The air fryer 100 is also provided with a driving member 4, which is arranged below the cooking fan 3. A reflective cover 8 is installed between the cooking fan 3 and the driving member 4. The reflective cover 8 is used to separate the installation cavity from the driving member 4 to prevent the airflow in the installation cavity from contacting the driving member 4. The driving member 4 is provided with a driving shaft 41, which can vertically penetrate the reflective cover 8 and extend into the installation cavity.

[0033] The first coupling member 5 may be connected to the driving shaft 41, and the second coupling member 6 may be connected to the cooking fan 3; or the second coupling member 6 may be connected to the driving shaft 41, and the first coupling member 5 may be connected to the cooking fan 3. By detachably connecting the first coupling member 5 and the second coupling member 6, the cooking fan 3 can be detachably connected to the driving member 4, so that the driving member 4 can drive the cooking fan 3 to rotate.

[0034] Specifically, when the user needs to clean the cooking fan 3, the heating plate 2 can be detached from the housing 1 through the opening so that the cooking fan 3 is exposed to the outside, and then the first coupling member 5 and the second coupling member 6 are separated to detach the cooking fan 3 from the housing 1 and clean it. After the cooking fan 3 is cleaned, the first coupling member 5 and the second coupling member 6 can be connected to install the cooking fan 3 to the driving member 4, and then the heating plate 2 is installed in the housing 1. In this way, the cooking fan 3 can be cleaned conveniently, the cleanliness of the cooking cavity 11 is improved, and the user's satisfaction is improved.

[0035] According to the air fryer 100 of the embodiment of the present invention, the driving member 4 and the cooking fan 3 are respectively connected to the first coupling member 5 and the second coupling member 6, and the first coupling member 5 and the second coupling member 6 are detachably connected, so that the cooking fan 3 is easy to disassemble and assemble, and convenient to clean, which reduces the difficulty of cleaning the air fryer 100, is conducive to improving the cleanliness of the air fryer 100, and improves user satisfaction.

[0036] In some embodiments of the present invention, the first coupling member 5 includes a coupling body 51 and a limiting spring piece 52 . The limiting spring piece 52 is installed on the coupling body 51 , and the limiting spring piece 52 is used to engage with the second coupling member 6 for limiting position.

[0037] For example, refer to Figure 1-Figure 2 As shown, the first coupling member 5 includes a coupling body 51 and a limiting spring piece 52. The limiting spring piece 52 is installed on the coupling body 51. The limiting spring piece 52 is used to apply elastic force to the second coupling member 6, so that the limiting spring piece 52 can be engaged and limited with the second coupling member 6 to install the second coupling member 6 to the first coupling member 5.

[0038] Specifically, during the installation of the cooking fan 3, the first coupling member 5 can be brought into contact with the second coupling member 6, so that the limiting spring piece 52 is deformed and an elastic force is applied to the second coupling member 6, so that the limiting spring piece 52 can be engaged with the second coupling member 6 to limit the position, thereby connecting the first coupling member 5 and the second coupling member 6; and during the removal of the cooking fan 3, an external force can be applied to the cooking fan 3, and the external force drives the limiting spring piece 52 to deform, so that the first coupling member 5 and the second coupling member 6 are separated. In this way, the difficulty of disassembling the cooking fan 3 can be reduced, and the difficulty of cleaning the air fryer 100 can be reduced.

[0039] Furthermore, the limiting spring piece 52 can be detachably connected to the coupling body 51, so that when the first coupling member 5 is damaged, the limiting spring piece 52 can be separated from the coupling body 51 and the damaged part can be replaced, which is conducive to reducing maintenance costs and improving user satisfaction.

[0040] In some embodiments of the present invention, the coupling body 51 is formed with an inserting slot 511 , and at least a portion of the limiting spring piece 52 extends into the inserting slot 511 and is snap-fitted with the plug connector 61 of the second coupling member 6 .

[0041] For example, refer to Figure 2-Figure 4As shown, a plugging groove 511 may be formed on one side of the coupling body 51 facing the second coupling member 6, and a plug connector 61 may be formed on one end of the second coupling member 6 facing the first coupling member 5. The plug connector 61 is matched with the plugging groove 511 so that the plug connector 61 can be plugged into the plugging groove 511. The plugging groove 511 is generally configured as a square structure. When the plug connector 61 is plugged into the plugging groove 511, the first coupling member 5 can limit the second coupling member 6 along the circumferential direction to prevent the first coupling member 5 and the second coupling member 6 from rotating relative to each other.

[0042] At the same time, at least a portion of the limiting spring piece 52 can be arranged to extend into the plug-in slot 511. When the plug connector 61 is plugged into the plug-in slot 511, the limiting spring piece 52 can be deformed to apply an elastic force along the axial direction of the drive shaft 41 to the plug connector 61. The elastic force is used to fix the plug connector 61 in the plug-in slot 511 to achieve stable installation of the first coupling member 5 and the second coupling member 6.

[0043] Through the above-mentioned arrangement, the installation stability of the first coupling member 5 and the second coupling member 6 can be improved, relative rotation between the cooking fan 3 and the driving shaft 41 can be avoided, and the cooking fan 3 can be prevented from automatically detaching from the driving shaft 41, thereby improving the reliability of the air fryer 100.

[0044] In some embodiments of the present invention, the limiting spring piece 52 is installed on the side of the coupling body 51 away from the plug-in slot 511, and the limiting spring piece 52 includes a plurality of spring piece parts 522, and the plurality of spring piece parts 522 respectively penetrate the coupling body 51 to extend into the plug-in slot 511, and the spring piece part 522 forms an elastic limiting part 523, and the elastic limiting part 523 is snap-fitted with the plug connector 61.

[0045] For example, refer to Figure 2-Figure 4 As shown, the limiting spring piece 52 can be installed on the side of the coupling body 51 away from the plug-in slot 511, and the limiting spring piece 52 includes a main body 521 and a plurality of spring pieces 522, and the plurality of spring pieces 522 are respectively connected to the outer peripheral wall of the main body 521. The spring pieces 522 are configured to extend in the direction close to the second coupling member 6, so that the plurality of spring pieces 522 can respectively penetrate the coupling body 51 to extend into the plug-in slot 511, and the spring pieces 522 are attached to the inner wall of the plug-in slot 511, and the end of the spring pieces 522 is formed with an elastic limiting portion 523 protruding inward. When the plug connector 61 extends into the plug-in slot 511, the elastic limiting portion 523 can be deformed to avoid the plug connector 61, and when the plug connector 61 is installed in place, the elastic limiting portion 523 can be restored and pressed against the side of the plug connector 61 away from the first coupling member 5, so as to fix the plug connector 61 in the plug-in slot 511.

[0046] It can be understood that by providing multiple spring pieces 522, the multiple spring pieces 522 can limit the plug connector 61 from different positions, thereby improving the installation stability between the first coupling member 5 and the second coupling member 6, improving the installation stability between the cooking fan 3 and the driving member 4, and improving the reliability of the air fryer 100.

[0047] In some embodiments of the present invention, Figure 3 As shown, a plurality of spring pieces 522 are evenly spaced and arranged along the circumference of the coupling body 51. Through the above arrangement, the limiting effect of the limiting spring piece 52 on the plug connector 61 can be improved, the installation stability between the first coupling member 5 and the second coupling member 6 is improved, the installation stability between the cooking fan 3 and the driving member 4 is improved, and the reliability of the air fryer 100 is improved.

[0048] In some embodiments of the present invention, a plurality of first connection portions are formed on a side of the coupling body 51 away from the insertion slot 511 , and the plurality of first connection portions are respectively connected to the plurality of elastic sheet portions 522 one by one.

[0049] For example, refer to Figure 3 As shown, a first connection portion may be formed on one side of the coupling body 51 away from the insertion slot 511, and the first connection portion is provided in plurality, and the plurality of first connection portions are provided at intervals along the circumference of the coupling body 51, and the plurality of first connection portions correspond to and are connected with the plurality of spring pieces 522 one by one, so as to fix the limiting spring piece 52 on the coupling body 51. Through the above arrangement, the installation stability of the limiting spring piece 52 can be improved, the installation stability between the first coupling member 5 and the second coupling member 6 can be improved, and the reliability of the air fryer 100 can be improved.

[0050] In some embodiments of the present invention, the first connecting portion is configured as a connecting boss 512, and the connecting boss 512 is riveted to the spring portion 522. Figure 3 As shown, the first connection portion can be constructed as a connection boss 512, the connection boss 512 is protruding upward, and the connection boss 512 can penetrate the spring sheet portion 522 and be riveted to the spring sheet portion 522 to fix the limiting spring sheet 52 and the coupling body 51 together. Through the above arrangement, no additional connection member is required, the number of parts of the first coupling member 5 can be reduced, and the processing cost can be reduced.

[0051] Further, refer to Figure 2 As shown, when the first coupling member 5 is connected to the cooking fan 3, a connecting boss 512 can be set to pass through the spring piece portion 522 and the cooking fan 3 in sequence and be riveted to the cooking fan 3, so that the coupling body 51, the limiting spring piece 52 and the cooking fan 3 can be connected as a whole, thereby improving the installation stability of the cooking fan 3 and helping to improve the reliability of the air fryer 100.

[0052] In some embodiments of the present invention, the first connection portion is configured as a threaded hole, and the connection member passes through the spring piece portion 522 and is threadedly connected to the threaded hole. For example, the first connection portion can be configured as a threaded hole, the threaded hole is open upward, and the connection member can pass through the spring piece portion 522 from top to bottom to extend into the threaded hole, so as to detachably connect the limiting spring piece 52 to the coupling body 51. In this way, the maintenance difficulty and maintenance cost of the first coupling member 5 can be reduced.

[0053] Furthermore, when the first coupling member 5 is connected to the cooking fan 3, a connecting member can be arranged to sequentially penetrate the cooking fan 3 and the spring piece portion 522 to extend into the threaded hole, so that the coupling body 51, the limiting spring piece 52 and the cooking fan 3 can be connected as one, thereby improving the installation stability of the cooking fan 3 and helping to improve the reliability of the air fryer 100.

[0054] In some embodiments of the present invention, the driving member 4 is provided with a driving shaft 41 , one of the first coupling member 5 and the second coupling member 6 is provided with an assembly hole 53 , and the end of the driving shaft 41 is inserted into the assembly hole 53 .
