[0041] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0042] like Figures 1 to 6 As shown, this embodiment of the present disclosure provides an air conditioner including multiple fan blades 21, with support components arranged between the multiple fan blades 21 to support the corresponding fan blades 21. Furthermore, the length of any blade of the fan blade 21 is less than or equal to 100cm. This ensures the overall airflow of the air conditioner while enhancing the stability of the fan blade rotation and preventing a decrease in the rigidity of the fan blades 21 due to excessive length. This design prevents the fan blades 21 from deforming or even breaking during high-speed rotation, thereby ensuring the safety and service life of the equipment.

[0043] like Figures 1 to 6As shown, this embodiment of the present disclosure provides an air conditioner including: a housing 10, a fan blade assembly 20, and a support assembly. The housing 10 is provided with a volute compartment; the fan blade assembly 20 is disposed in the volute compartment, and the fan blade assembly 20 includes a plurality of fan blades 21, which are coaxially arranged, and adjacent fan blades 21 are connected by a connecting shaft 22; the support assembly is installed on the housing 10, and at least one support assembly is provided between any two adjacent fan blades 21, and the connecting shaft 22 passes through the support assembly; wherein, the fan blades 21 are provided with a plurality of blades 211, which are arranged parallel to the axis of the fan blades 21, and the length of the blades 211 is less than or equal to 100cm.

[0044] Specifically, a volute chamber is provided inside the housing 10, and the size of the volute chamber is greater than or equal to the size of the fan blade assembly 20. The fan blade assembly 20 is installed inside the volute chamber, and multiple fan blades 21 of the fan blade assembly 20 are coaxially arranged in the horizontal direction, and the fan blades 21 can rotate around their axes. Adjacent fan blades 21 are connected by a connecting shaft 22, which can be a separate structure or an integrated structure, as long as it can ensure that multiple fan blades 21 rotate synchronously. The fan blades 21 are also provided with a cylindrical impeller, and the blades 211 are arranged around the impeller, and multiple blades 211 are arranged in parallel. In this way, multiple fan blades 21 can rotate synchronously and deliver air through the blades 211. At the same time, the length of any blade 211 is less than or equal to 100cm. This ensures the overall air volume of the air conditioner, enhances the stability of the fan blade rotation, and prevents the fan blades 21 from becoming too long, which would reduce their rigidity. This design can prevent the fan blade 21 from deforming or even breaking during high-speed rotation, thus ensuring the safety and service life of the equipment.

[0045] In practical applications, the length of blade 211 can be selected according to the user's actual needs. For example, the length of blade 211 can be 100cm, 90cm, 80cm, 70cm or 60cm.

[0046] Optionally, the sum of the lengths of the multiple fan blades 21 is greater than or equal to 100cm to ensure the air volume and air delivery area of ​​the air conditioner.

[0047] Optionally, the blades 211 of the multiple fan blades 21 can be the same length or different lengths. For example, if the blade 211 of one fan blade 21 is 100cm long, then the blade 211 of another fan blade 21 can be 100cm long or 90cm long. This configuration allows the fan blade assembly 20 to be adapted to more models of air conditioners.

[0048] Optionally, the shape and size of the volute compartment correspond to the lower half of the fan blade assembly 20. The air conditioner also includes a volute compartment cover, the shape and size of which correspond to the upper half of the fan blade assembly 20, and the volute compartment cover can be placed on top of the volute compartment. In this way, after the fan blade assembly 20 is installed in the volute compartment, the volute compartment cover can be placed on top of the fan blade assembly 20 to form an air duct with the volute compartment while preventing debris from entering the volute compartment.

[0049] like Figures 2 to 4 As shown, in some embodiments, the support assembly includes a support base 31 and a support cover 32. The support base 31 is fixedly installed inside the volute housing, and the support base 31 is provided with a support groove 311 corresponding to the connecting shaft 22, and the lower half of the connecting shaft 22 is embedded in the support groove 311; the support cover 32 is fastened to the top of the support base 31, and the support cover 32 is provided with a limiting groove 321 corresponding to the connecting shaft 22, and the limiting groove 321 is fastened to the upper half of the connecting shaft 22.

[0050] Specifically, the support base 31 can be fixedly installed to the volute housing via snap-fit ​​components or fasteners to divide the volute housing into multiple sub-volute housings, and multiple fan blades 21 can be installed in multiple sub-volute housings respectively. The lower half of the connecting shaft 22 is embedded in the support groove 311, and the limiting groove 321 is engaged with the upper half of the connecting shaft 22. When the support cover 32 is engaged with the support base 31, the limiting groove 321 can cooperate with the support groove 311 to form a complete mounting hole, and the mounting hole is coaxial with the fan blade 21. In this way, after the multiple fan blades 21 and the connecting shaft 22 are installed, the fan blades 21 can be supported by the support base 31 and limited by the support cover 32. The shape of the support base 31 corresponds to the volute housing setting so that the support base 31 can fit snugly into the volute housing setting, thereby ensuring the stability of the support base 31 supporting the fan blades 21.

[0051] Optionally, the support base 31 has a slot 312 at its end corresponding to the outer edge of the volute housing, and the slot 312 can be engaged with the outer edge of the volute housing. Simultaneously, the support base 31 has screw holes 33 corresponding to the inner edge of the volute housing or the peripheral wall of the volute housing. Thus, when installing the support base 31, the slot 312 can be engaged with the outer edge of the volute housing first, and then bolts or screws can be used to fasten the support base 31 to the volute housing by engaging the screw holes 33.

[0052] like Figures 2 to 4 As shown, in some embodiments, the support base 31 is provided with a downward-curved edge, and the downward-curved edge abuts against the outer wall of the lower half of the fan blade 21; the support cover 32 is provided with an upward-curved edge, and the upward-curved edge abuts against the outer wall of the upper half of the fan blade 21.

[0053] Specifically, the support base 31 has a downward-curved edge along its edge, which bends and extends towards the lower half of the fan blade 21. This allows the outer wall of the lower half of the fan blade 21 to abut against the inner wall of the downward-curved edge after the support base 31 and fan blade 21 are installed, increasing the stability of the support base 31 in supporting the fan blade 21. Similarly, the support cover 32 has an upward-curved edge along its edge, which bends and extends towards the upper half of the fan blade 21. This allows the inner wall of the upward-curved edge to abut against the outer wall of the upper half of the fan blade 21 after the support cover 32 is fastened to the support base 31, increasing the fixing effect of the support cover 32 on the fan blade 21.

[0054] In the above embodiments, the lengths of the lower and upper flanges are less than or equal to a preset length to avoid the lower and upper flanges affecting the air delivery effect of the fan blade 21.

[0055] like Figures 2 to 4 As shown, in some embodiments, the support base 31 is provided with a card interface 313, and the support cover 32 is provided with a buckle 322 corresponding to the card interface 313; wherein, the buckle 322 can be snapped into the card interface 313.

[0056] Specifically, the support base 31 has a locking interface 313 on the side facing the support cover 32, and the locking interface 313 is located on the side wall or this end of the support base 31. The support cover 32 has a buckle 322 corresponding to the locking interface 313, and the buckle 322 can be locked into the locking interface 313. In this way, after the support cover 32 is fastened to the support base 31, the buckle 322 can be locked into the locking interface 313 to fix the support cover 32 to the support base 31.

[0057] like Figures 2 to 4 As shown, optionally, the support base 31 is also provided with screw holes 33, and the screw holes 33 and the snap-fit ​​interface 313 are disposed opposite each other at two ends or two side walls of the support base 31. The support cover 32 is also provided with screw holes 33 and snap-fit ​​322 corresponding to the screw holes 33 and the snap-fit ​​interface 313. In this way, after the support cover 32 is fastened to the support base 31 and the snap-fit ​​322 is snapped into the snap-fit ​​interface 313, the support cover 32 can be fastened to the support base 31 by fasteners such as screws or bolts in conjunction with the screw holes 33.

[0058] Optionally, the support base 31 is provided with two card interfaces 313, and the two card interfaces 313 are respectively provided at two ends or two side walls of the support base 31. The support cover 32 is provided with two buckles 322 corresponding to the two card interfaces 313, and the two buckles 322 can be respectively engaged with the two card interfaces 313.

[0059] like Figures 1 to 6As shown, in some embodiments, the housing 10 is further provided with an air inlet; the air conditioner also includes an air inlet grille 40. The air inlet grille includes a swivel blade 42, which is rotatably disposed at the air inlet, and the width of the swivel blade 42 is smaller than the width of the air inlet.

[0060] Specifically, the air inlet is located on the side wall of the casing 10, and the fan assembly 20 draws outside air into the casing 10 through the air inlet. An air inlet grille 40 is located at the air inlet, and the size of the air inlet grille is greater than or equal to the size of the air inlet, so that the air inlet grille 40 can be completely fastened to the air inlet. The oscillating blade 42 can rotate circumferentially around its axis, and the width of the oscillating blade 42 is smaller than the size of the air inlet. Thus, by controlling the rotation of the oscillating blade 42 to different angles, the area of ​​the air inlet that is cleared can be adjusted, thereby adjusting the air intake volume. At the same time, because the size of the oscillating blade 42 is smaller than the size of the air inlet, the oscillating blade 42 cannot completely block the air inlet, thus avoiding affecting the normal operation of the air conditioner.

[0061] like Figure 5 and Figure 6 As shown, in some embodiments, the air conditioner further includes an intake motor 12 and a control device. The intake motor 12 includes a drive shaft that is tractively connected to the swivel blades 42; the control device is electrically connected to the intake motor 12; wherein the control device is used to control the intake motor 12 to drive the swivel blades 42 to rotate.

[0062] Specifically, the intake motor 12 is located on one side of the swing blade 42, and the drive shaft of the intake motor 12 is connected to the swing blade 42 to drive the swing blade 42 to rotate. In this way, the intake motor 12 can be controlled by the control device to drive the swing blade 42 to rotate, thereby adjusting the air intake volume of the air inlet.

[0063] Understandably, the air intake motor 12 can also act as a brake on the swing blade 42. In this way, after the angle of the swing blade 42 is adjusted, the air intake motor 12 can limit the swing blade 42 to prevent it from rotating under the action of airflow.

[0064] like Figures 1 to 6 As shown, in some embodiments, the housing 10 is also provided with an air outlet; the air conditioner also includes: an air guide plate 11 and an angle sensor. The air guide plate 11 is rotatably disposed at the air outlet; the angle sensor is used to obtain the first included angle α1 between the air guide plate 11 and the air outlet; wherein, the control device is also electrically connected to the angle sensor, and the control device is used to control the rotation of the oscillating blade 42 according to the first included angle, so as to adjust the second included angle α2 between the oscillating blade 42 and the air inlet.

[0065] Specifically, the air outlet is also located on the side wall of the housing 10, and the fan blades 21 can blow air out of the housing 10 through the air outlet. The air guide plate 11 is rotatably mounted at the air outlet to adjust the air delivery angle and air volume of the air outlet. An angle sensor is used to acquire the first included angle α1 between the air guide plate 11 and the air outlet in real time, and transmit the information of the first included angle α1 of the air guide plate 11 to the control device. After acquiring the first included angle α1, the control device can control the air intake motor 12 to drive the swing blades 42 to rotate according to the first included angle α1, so as to adjust the second included angle α2 between the swing blades 42 and the air intake.

[0066] In the above embodiments, if the air outlet is curved, the angle between the air guide plate 11 and the air outlet refers to the angle between the tangents of the air guide plate 11 and the air outlet at the connection between the air guide plate 11 and the housing 10. Similarly, if the air inlet is curved, the angle between the oscillating blade 42 and the air inlet refers to the angle between the oscillating blade 42 and the tangent of the air inlet at the connection between the oscillating blade 42 and the housing 10.

[0067] like Figure 5 and Figure 6 As shown, in some embodiments, the first included angle α1 is greater than or equal to 60° and less than or equal to 120°; the second included angle α2 is greater than or equal to 0° and less than or equal to 90°; wherein the second included angle α2 and the first included angle α1 are directly proportional.

[0068] Specifically, the first included angle α1 can be set according to the user's actual selection. For example, the first included angle α1 can be 60°, 80°, 100°, or 120°. The larger the first included angle α1, the greater the air volume from the air outlet. The second included angle α2 can be set based on the first included angle α1. The second included angle α2 is greater than or equal to 0° and less than or equal to 90°. For example, the second included angle α2 can be 0°, 40°, 60°, or 90°. A second included angle α2 of 0° means the oscillating blade 42 is perpendicular to the air inlet, at which point the air volume at the air inlet reaches its maximum; and a second included angle α2 of 90° means the oscillating blade 42 is parallel to the air inlet, at which point the air volume at the air inlet reaches its minimum. Furthermore, the second included angle α2 and the first included angle α1 are directly proportional; that is, the larger the first included angle α1, the larger the second included angle α2. For example, if the first included angle α1 is 60°, then the second included angle α2 is 0°; if the first included angle α1 is 120°, then the second included angle α2 is 90°.

[0069] Understandably, the smaller the angle between the air guide plate 11 and the air outlet, the greater the air outlet resistance; conversely, the larger the angle, the smaller the air outlet resistance. Similarly, the smaller the angle between the swivel blade 42 and the air inlet, the greater the air inlet resistance; and the larger the angle, the smaller the air inlet resistance. Furthermore, during air conditioner operation, the air guide plate 11 rotates to adjust the airflow direction and volume to adapt to different indoor environments. However, during the rotation of the air guide plate 11, changes in air outlet resistance occur, affecting the stability of the air supply system. Therefore, by adjusting the second angle α2 according to the first angle α1, the air inlet resistance is made to match the air outlet resistance in real time. This configuration allows for adjustment of the air inlet volume based on the overall air outlet volume of the air conditioner, thus avoiding impacts on the stability of the air supply system.

[0070] like Figure 5 and Figure 6 As shown, in some embodiments, the air inlet grille includes a plurality of sway blades 42 arranged in parallel with gaps between them; the air inlet grille also includes a connecting rod 43. The connecting rod 43 is rotatably connected to the plurality of sway blades 42 respectively; wherein, the air inlet motor 12 is drivenly connected to the connecting rod 43 to drive the plurality of sway blades 42 to rotate synchronously.

[0071] Specifically, multiple blades 42 are arranged in parallel at the air inlet, with gaps between them. Each blade 42 is connected to a connecting rod 43, allowing the air intake motor 12 to simultaneously drive all blades to rotate. This arrangement prevents any single blade 42 from becoming too large, thus minimizing the space occupied by the air conditioner.

[0072] like Figure 5 and Figure 6 As shown, in some embodiments, the air inlet grille further includes a grille plate 41. The grille plate 41 is disposed at the air inlet and has multiple ventilation openings; wherein, the air inlet grille includes multiple swivel blades 42, which are rotatably disposed at the multiple ventilation openings, and the width of the swivel blades 42 is smaller than the width of the ventilation openings.

[0073] Specifically, the oscillating blade 42 and connecting rod 43 are mounted on the grille plate 41, which provides support for the oscillating blade 42 and connecting rod 3. At the same time, the grille plate 41 also prevents foreign objects from entering the housing 10.
