[0027] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0028] As shown in Figures 1-9, an openable air fryer includes a main unit 1. Inside the main unit 1 are a fan assembly 2 and a heating element assembly 3. The heating element assembly 3 is positioned in the air outlet path of the fan assembly 2 and is adjacent to it. The main unit 1 includes an openable main shell 11 and a secondary shell 12. The fan assembly 2 is mounted on the secondary shell 12, and the heating element assembly 3 is mounted on the main shell 11. The opening and closing structure of the main shell 11 and the secondary shell 12 can be any one of hinged, sliding, detachable, or rotating types. When the main unit 1 is opened or detached, the fan assembly 2 and the heating element assembly 3 also move away, facilitating deep cleaning of the main unit 1 by the operator.

[0029] Specifically, the secondary housing 12 is hinged to the primary housing 11. A torsional elastic element is provided at the hinge point between the primary housing 11 and the secondary housing 12. A latching structure 14, which is linked to the opening / closing button 13, is provided between the primary housing 11 and the secondary housing 12. The latching structure 14 engages or disengages, allowing the primary housing 11 and the secondary housing 12 to close or flip open. The hinged opening and closing structure ensures convenient opening and closing without affecting internal cleaning.

[0030] Regardless of the opening and closing structure, a contact sensor 7 is typically installed at the interface between the main housing 11 and the secondary housing 12. The contact sensor 7 is connected to the power supply and control circuits of the main unit 1. This contact sensor 7 detects whether the main housing 11 and the secondary housing 12 are in a closed state. If they are not closed, the internal circuitry of the main unit 1 is de-energized, and the fan assembly 2 and the heating element assembly 3 are also turned off. Only when the main unit 1 is closed and the switch is pressed to start it can various operations be performed on the main unit, thus ensuring user safety during cleaning.

[0031] Unlike conventional fixed fans, the fan assembly 2 in this embodiment adopts a detachable structure, specifically including a convection fan 21 installed inside the main unit 1 and connected to the drive structure. The convection fan 21 is assembled and connected to the main unit 1 via a quick-release threaded fitting 22. The quick-release threaded fitting 22 is provided with an easily removable nut gripping part parallel to the central axis of the thread. When cleaning, the user can grasp the motor shaft fixed to the convection fan 21 with one hand and squeeze the easily removable nut gripping part with the other hand to rotate, thereby removing the quick-release threaded fitting 22 and the convection fan 21, and then cleaning the convection fan 21 and the fryer cavity of the main unit 1 that is blocked by the convection fan 21.

[0032] Preferably, the main unit 1 of this embodiment has a pull-out opening 8 on its side, and a slidable and pull-out basket 81 is installed inside the pull-out opening 8. The basket 81 has a cover plate 82 that closes the pull-out opening 8, and a handle 83 is fixed on the cover plate 82.

[0033] Example 1

[0034] As shown in Figure 1, in this embodiment, the secondary housing 12 is hinged to the main housing 11. A torsional elastic element is provided at the hinge point between the main housing 11 and the secondary housing 12. A latching structure 14 that is linked to the opening and closing button 13 is provided between the main housing 11 and the secondary housing 12. The latching structure 14 engages or disengages to close the main housing 11 and the secondary housing 12 or flips them open.

[0035] In this embodiment, the heating tube assembly 3 is fixedly connected to the host 1. The heating tube assembly 3 and the main housing 11 adopt a fixed structure. This structure is relatively simple. The inner side of the main housing 11 and the heating tube assembly 3 can be cleaned simply by pulling out the basket 81.

[0036] Example 2

[0037] As shown in Figures 3-5, in this embodiment, the secondary housing 12 is hinged to the main housing 11. A torsional elastic element is provided at the hinge point between the main housing 11 and the secondary housing 12. A latching structure 14 that is linked to the opening and closing button 13 is provided between the main housing 11 and the secondary housing 12. The latching structure 14 engages or disengages to close the main housing 11 and the secondary housing 12 or flips them open.

[0038] In this embodiment, the heating tube assembly 3 is rotatably connected to the main unit 1. The heating tube assembly 3 includes a fixing frame 31 and a heating coil 32 is installed on the fixing frame 31. The fixing frame 31 has an extension arm 33. The heating coil 32 and the fixing frame 31 are either separate or integrally formed. A flip seat 4 is fixed at the end of the extension arm 33. A flip seat slot 34 is provided on the main housing 11. The flip seat 4 and the main housing 11 are movably connected at the flip seat slot 34 and an elastic component 37 is provided between them. A movable joint 35 is provided inside the cooking cavity of the main housing 11. An unlocking key 36 that is interlocked with the movable joint 35 is provided outside the main housing 11. The heating tube assembly 3 has a flip joint 38 corresponding to the movable joint 35.

[0039] One end of the elastic component 37 presses into the flip seat 4, and the other end presses into a fixed surface of the main housing 11, causing the flip seat 4 to tend to open relative to the main housing 11. The flip seat 4 is snapped onto the flip seat fixing block 42 via a snap-fit ​​joint, and the flip seat fixing block 42 is fixed to the main housing 11 by screws 43. The flip seat 4 can rotate around the snap-fit ​​joint and the flip seat fixing block 42. One end of the elastic component 37 presses onto the flip seat 4, and the other end presses onto the flip seat fixing block 42. The elastic component 37 is a torsion spring with a certain preload, causing the flip seat 4 and the flip seat fixing block 42 to have a tendency to rotate. The heating coil 32 is unlocked by pressing the unlocking component 36 to rotate it, rather than by manually pulling the heating coil 32. This avoids the potential risk of burns and also avoids the loosening and deformation of the heating coil 32 that may be caused by manually pulling it.

[0040] Example 3

[0041] As shown in Figures 6-9, in this embodiment, the secondary housing 12 is hinged to the main housing 11. A torsional elastic element is provided at the hinge point between the main housing 11 and the secondary housing 12. A latching structure 14 that is linked to the opening and closing button 13 is provided between the main housing 11 and the secondary housing 12. The latching structure 14 engages or disengages to close the main housing 11 and the secondary housing 12 or flips them open.

[0042] In this embodiment, the heating tube assembly 3 is rotatably connected to the main unit 1. The heating tube assembly 3 includes a fixing frame 31 on which a heating coil 32 is mounted. The fixing frame 31 has an extension arm 33. A rotating seat 5 is fixed at the end of the extension arm 33. A rotating slot 51 is formed at the junction of the main housing 11 and the secondary housing 12. A limiting frame 52 is built into the rotating slot 51. The limiting frame 52 provides support for the heating tube assembly 3 and improves the sealing of its rotating connection, ensuring the internal and external isolation of the main unit 1 in the closed state. The heating tube assembly 3 is provided with a cable threading hole 67, and the corresponding rotating slot 51 is provided with a threading channel. When the heating tube assembly 3 rotates relative to the rotating slot 51, the wire of the heating tube assembly 3 passes through the cable threading hole 67 and the threading channel to connect with the internal circuit of the main unit 1, without affecting its rotational flexibility, ensuring that the heating coil 32 can rotate freely within the range of 0-150°.

[0043] The rotating seat 5 is located on the inward side of the limiting frame 52. A rotating frustum 53 is provided at the end of the rotating seat 5 opposite to the limiting frame 52. The limiting frame 52 has a limiting clamp 54 for the rotating frustum 53 to be inserted and rotated. A groove is left between the limiting clamp 54 and the limiting frame 52 for the limiting clamp 54 to undergo elastic deformation. The rotating frustum 53 can be separated from the limiting clamp 54 to achieve overall disassembly, cleaning and maintenance of the heating tube assembly 3.

[0044] A limiting post 55 is fixed on the side of the limiting frame 52 away from the rotating base 5, and a positioning contact 56 is movably installed at the end of the limiting post 55. The limiting post 55 has a built-in elastic element that pushes the positioning contact 56 outward. A disc 57 is provided on the side of the limiting frame 52 away from the rotating base 5, which engages with the rotating slot 51 and rotates. A limiting groove 58 is opened on the side of the disc 57 opposite to the limiting frame 52 for the limiting post 55 to be inserted and slidably limited. A positioning hole 59 is opened at the end of the limiting groove 58 for the positioning contact 56 to be pushed in. A cover 6 is provided on the side of the disc 57 away from the limiting frame 52. A release mechanism is fixed on the side of the cover 6 opposite to the disc 57. The positioning press post 61 has a spring mounting groove 62 between the cover 6 and the disc 57, and a reset spring 63 is built into the spring mounting groove 62. The positioning press post 61 is pressed into the positioning hole 59 along with the cover 6. A handle 64 is fixed on the side of the cover 6 away from the disc 57. The rotating seat 5 has a coil shaft 65 extending along the axial direction. The disc 57 and the cover 6 have a connecting hole 66 for the coil shaft 65 to pass through and for circumferential limitation. The cover 6 and the disc 57 are fixed to the coil shaft 65 by screws 68. A cable threading hole 67 is opened on the side of the rotating seat 5.

[0045] When the heating tube assembly 3 is in a horizontal state, the positioning contact 56 is inserted into the positioning hole 59 at the end of the limiting groove 58 to lock the position. When it is necessary to flip the heating tube assembly 3, press the cover 6 and rotate the handle 64. At this time, the positioning pressing post 61 is released from the positioning hole 59 and the positioning contact 56 is pushed out from the positioning hole 59. The rotating seat 5, the cover 6 and the disc 57 rotate synchronously under the circumferential limiting action of the coil shaft 65. The heating tube assembly 3 flips, and the limiting post 55 slides along the limiting groove 58 to limit the flipping angle range of the heating tube assembly 3.

[0046] In summary, the principle of this embodiment is as follows: the host 1 adopts an openable main housing 11 and a secondary housing 12. When the main housing 11 and the secondary housing 12 are in the open state, the fan assembly 2 and the heating tube assembly 3 are also moved away and located in different housings, providing the host 1 with sufficient cleaning operation space.
