[0002] Air conditioners are widely used for adjusting the temperature of indoor environments. Generally, existing air conditioners are provided with a wind sweeping component at the air duct opening, and the air outlet direction of the air conditioner is adjusted by adjusting the wind sweeping direction of the wind sweeping component. However, the disassembly and assembly of the existing wind sweeping component are cumbersome, and limited by the air duct installation space and the structure of the wind sweeping blades in the wind sweeping component, the wind guiding area of the wind sweeping blades for the air outlet of the air duct is small and the wind guiding effect is poor. Summary of the Utility Model

[0003] The purpose of the utility model includes providing a wind sweeping component and an air conditioner to solve the technical problems that the disassembly and assembly of the existing wind sweeping component are cumbersome, and limited by the air duct installation space and the structure of the wind sweeping blades in the wind sweeping component, the wind guiding area of the wind sweeping blades for the air outlet of the air duct is small and the wind guiding effect is poor.

[0004] To solve the above problems, the utility model provides a wind sweeping component applied to an air conditioner, which includes an air outlet grille.

Detailed implementation manners

[0027] To make the above-mentioned objects, features, and advantages of the present invention more obvious and understandable, the following will describe the specific embodiments of the present invention in detail with reference to the drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0028] This embodiment provides an air-sweeping assembly 30, which is applied to an air conditioner, such as Figure 4 andFigure 5 As shown, it includes an air outlet grille 100. Sweeping blades are integrally formed on both the upstream side and the downstream side of the air outlet grille 100, and the sweeping blades have a flexible part 420 that can be elastically bent to swing.

[0029] This embodiment also provides an air conditioner, as Figure 1 shown, which includes a housing 10 and the above-mentioned air sweeping assembly 30. The housing 10 has an air duct 20, and the air outlet grille 100 of the air sweeping assembly 30 is fixedly arranged on the duct wall of the air duct 20.

[0030] When the air sweeping assembly 30 provided in this embodiment is applied to an air conditioner, its air outlet grille 100 blocks the air duct 20 of the air conditioner, and can play a role in blocking and protecting the area of the air duct 20 opening, so as to reduce the occurrence of the situation where users accidentally put their hands into the air duct 20 and are injured by the cross-flow fan 60, etc.; the side of the air outlet grille 100 facing the inside of the air duct 20 is the upstream side, and the side facing the outside of the air conditioner is the downstream side. Correspondingly, among the sweeping blades, the sweeping blades located on the upstream side of the air outlet grille 100 are upstream sweeping blades 200, and the sweeping blades located on the downstream side of the air outlet grille 100 are downstream sweeping blades 300.

[0031] During use, the air flow blown out from the air duct 20 first reaches the upstream sweeping blades 200, and the rotation angle of the upstream sweeping blades 200 around their flexible part 420 is adjusted to adjust its air guiding direction; the air flow after the air guiding direction is adjusted by the upstream sweeping blades 200 then flows through the air outlet grille 100 and reaches the downstream sweeping blades 300. Similarly, the rotation angle of the downstream sweeping blades 300 around their flexible part 420 is adjusted to adjust its air guiding direction, and the air flow after the secondary direction adjustment by the downstream sweeping blades 300 is blown out from the air duct 20 opening in a preset direction, so as to realize the adjustment of the air outlet direction of the air conditioner.

[0032] Among them, upstream sweeping blades 200 are integrally formed on the upstream side of the air outlet grille 100, and downstream sweeping blades 300 are integrally formed on the downstream side. Both the upstream sweeping blades 200 and the downstream sweeping blades 300 are provided with flexible parts 420, and both can rotate around their flexible parts 420 to adjust the air guiding direction. On the one hand, the upstream sweeping blades 200 and the downstream sweeping blades 300 can successively adjust the flow direction of the air flow passing through twice. By adjusting the cooperation of the air guiding directions of the upstream sweeping blades 200 and the downstream sweeping blades 300, the diversity of the air guiding of the air sweeping assembly 30 can be improved, and correspondingly, the air outlet modes of the air conditioner can be increased and the functionality of the air conditioner can be improved.

[0033] On the other hand, the three components are integrally formed. On the basis of ensuring that the upstream air-sweeping blade 200 and the downstream air-sweeping blade 300 can adjust the air guiding direction, the processing convenience of the three components is higher and the processing cost is lower. At the same time, when assembling the air conditioner, only the air outlet grille 100 needs to be connected to the air duct wall to complete the installation of the entire air-sweeping assembly 30, without separately installing the upstream air-sweeping blade 200 and the downstream air-sweeping blade 300, thereby improving the assembly convenience of the air conditioner, and the position accuracy of the three components can be guaranteed. Similarly, when it is necessary to disassemble, clean and maintain the air outlet grille 100, the upstream air-sweeping blade 200 and the downstream air-sweeping blade 300, only the air outlet grille 100 needs to be removed to realize the disassembly of the three components, and the disassembly and maintenance convenience is also higher.

[0034] On the further hand, compared with the existing air-sweeping blades which generally need to be provided with connecting arms for connecting to the air outlet grille 100 or the air duct wall, the upstream air-sweeping blade 200 and the downstream air-sweeping blade 300 of the present application are integrally formed on the air outlet grille 100 without the need for connecting arms. At the same time, there is a seamless connection between the upstream air-sweeping blade 200 and the downstream air-sweeping blade 300 and the air outlet grille 100, which can increase the width and length of the air-sweeping blades within the limited space of the air duct 20, thereby increasing the air guiding area of the air-sweeping blades and reducing the air leakage amount between the air outlet grille 100 and the air-sweeping blades during the air guiding process, and further effectively improving the air guiding effect of the air-sweeping assembly 30.

[0035] Optionally, in this embodiment, as Figure 2 and Figure 3 shown, there are two air-sweeping assemblies 30, and the two air-sweeping assemblies 30 are arranged in sequence along the length direction of the air duct 20. By setting two air outlet assemblies to shorten the length of each air outlet assembly, thereby improving its processing convenience and mold release yield. Among them, the forms of the air outlet grilles 100, the numbers and arrangement forms of the upstream air-sweeping blades 200, and the numbers and arrangement forms of the downstream air-sweeping blades 300 in the two air-sweeping assemblies 30 can be the same or can be set differently according to needs.

[0036] Specifically, when the air conditioner is a floor-standing air conditioner, the air duct 20 extends vertically, and the two air-sweeping assemblies 30 are arranged in sequence in the vertical direction, and the left-right direction is the width direction of the air outlet grille 100 and the up-down direction is the length direction of the air outlet grille 100; when the air conditioner is a wall-mounted air conditioner, the air duct 20 extends horizontally, and the two air-sweeping assemblies 30 are arranged in sequence in the horizontal direction accordingly, and the left-right direction is the length direction of the air outlet grille 100 and the up-down direction is the width direction of the air outlet grille 100.

[0037] In this embodiment, there can be multiple upstream sweeping blades 200, and the multiple upstream sweeping blades 200 are arranged at intervals along the length direction or the width direction of the air outlet grille 100. The multiple upstream sweeping blades 200 can be arranged in columns along the length direction or the width direction of the air outlet grille 100, and the multiple upstream sweeping blades 200 can guide different regions of the flowing air, thereby improving the air guiding effect of the upstream sweeping blades 200 on the air flow. Similarly, there are multiple downstream sweeping blades 300, and the multiple downstream sweeping blades 300 are arranged in rows at intervals along the length direction or the width direction of the air outlet grille 100 to improve the air guiding effect of the downstream sweeping blades 300 on the air flow.

[0038] Taking the air conditioner as a floor-standing air conditioner as an example, the air outlet grille 100 is fixedly connected to the air outlet frame 21 of its air duct wall. The up-down direction is the length direction of the air outlet grille 100, and the left-right direction is the width direction of the air outlet grille 100. The multiple upstream sweeping blades 200 can be used as horizontal swing blades and are arranged vertically at intervals on the upstream side of the air outlet grille 100 along the up-down direction. The flexible parts 420 of the upstream sweeping blades 200 extend along the left-right direction. During use, the upstream sweeping blades 200 can swing up and down around the flexible parts 420 to adjust the up-down air outlet direction of the air flow in the air duct 20; or the multiple upstream sweeping blades 200 can be used as vertical swing blades and are arranged horizontally at intervals on the upstream side of the air outlet grille 100 along the left-right direction. The flexible parts 420 of the upstream sweeping blades 200 extend along the up-down direction. During use, the upstream sweeping blades 200 can swing left and right around the flexible parts 420 to adjust the left-right air outlet direction of the air flow in the air duct 20. The arrangement of the multiple downstream sweeping blades 300 is similar to the arrangement of the multiple upstream sweeping blades 200 described above and will not be elaborated here.

[0039] During use, the arrangement forms of the upstream sweeping blades 200 and the downstream sweeping blades 300 in the sweeping assembly 30 can be configured according to needs. For example, both the upstream sweeping blades 200 and the downstream sweeping blades 300 can be arranged vertically at intervals along the length direction of the air outlet grille 100 to improve the up-down air guiding effect of the sweeping assembly 30 on the air flow in the air duct 20; or, both the upstream sweeping blades 200 and the downstream sweeping blades 300 can be arranged horizontally at intervals along the width direction of the air outlet grille 100 to improve the left-right air guiding effect of the sweeping assembly 30 on the air flow in the air duct 20; or, one of the upstream sweeping blades 200 and the downstream sweeping blades 300 can be arranged vertically at intervals along the length direction of the air outlet grille 100, and the other can be arranged horizontally at intervals along the width direction of the air outlet grille 100 to achieve the up-down and left-right air guiding adjustment of the air flow in the air duct 20; at the same time, by adjusting the air guiding angles of the upstream sweeping blades 200 and the downstream sweeping blades 300, the air guiding diversity and air guiding effect of the sweeping assembly 30 can be greatly improved.

[0040] Specifically, in this embodiment, such as Figure 2 and Figure 3As shown, there are multiple upstream sweeping blades 200 of the two sweeping components 30, which are arranged at intervals along the length direction of the air outlet grille 100 thereof; the housing 10 is provided with an upstream driving component 40, and the upstream driving component 40 includes an upstream driving motor 41 and an upstream linkage rod 42 connected to the upstream driving motor 41. The upstream linkage rod 42 is provided with multiple upstream clamping holes 43 arranged at intervals along its length direction. The upstream sweeping blades 200 of the two sweeping components 30 are integrally formed with upstream linkage shafts 210, and each upstream linkage shaft 210 is rotatably clamped in the multiple upstream clamping holes 43 in a one-to-one correspondence. The arrangement forms of the upstream sweeping blades 200 in the two sweeping components 30 are the same and can jointly form a single long row. Using a single upstream driving motor 41 as the driving source, the synchronous linkage of all upstream driving components 40 is realized through the rotational clamping of the upstream linkage rod 42 and the upstream linkage shafts 210 of all upstream sweeping blades 200, thereby reducing the number of upstream driving components 40 and simplifying its structure. During use, the upstream driving motor 41 drives the upstream linkage rod 42 to move along the length direction of the air outlet grille 100, thereby driving all upstream sweeping blades 200 to rotate synchronously, and correspondingly realizing the synchronous adjustment of the diversion directions of the upstream sweeping blades 200.

[0041] Preferably, as Figure 3 shown, the rod segments of the upstream linkage rod 42 corresponding to the two sweeping components 30 are straight rod segments 42a, and the rod segment located between the two sweeping components 30 is a bent strengthening segment 42b to improve the strength of the entire upstream linkage rod 42.

[0042] Among them, each upstream sweeping blade 200 is integrally formed with an upstream linkage shaft 210 to realize the rotational connection with the upstream linkage rod 42, with a simple structure, high processing convenience, and a relatively high connection firmness between the upstream linkage shaft 210 and the corresponding upstream sweeping blade 200.

[0043] Specifically, as Figure 2As shown, there are multiple downstream sweeping blades 300 of the two air-sweeping components 30, which are arranged at intervals along the width direction of the air outlet grille 100; the housing 10 is provided with two downstream driving components 50, and each downstream driving component 50 includes a downstream driving motor 51 and a downstream linkage rod 52 connected to the downstream driving motor 51. The downstream linkage rod 52 is provided with multiple downstream locking holes 53 arranged at intervals along its length direction. The downstream linkage shafts 310 of the downstream sweeping blades 300 of the two air-sweeping components 30 are integrally formed. The two downstream linkage rods 52 correspond to the two air-sweeping components 30 one by one, and the downstream linkage shafts 310 of the multiple downstream sweeping blades 300 of the same air-sweeping component 30 are rotatably and snap-connected to the multiple locking holes of the corresponding downstream linkage rod 52 one by one. During use, the two downstream driving motors 51 respectively drive the corresponding downstream linkage rods 52 to move along the width direction of the air outlet grille 100, thereby driving the corresponding multiple downstream sweeping blades 300 to rotate synchronously, realizing synchronous adjustment of the diversion direction of the downstream sweeping blades 300.

[0044] Specifically, in this embodiment, as Figure 2 and Figure 3 shown, the air outlet grille 100 includes multiple horizontal grille bars 110 and multiple vertical grille bars 120 arranged in a crosswise manner. At least some of the horizontal grille bars 110 serve as horizontal connecting grille bars. The sweeping blades located on the upstream side of the air outlet grille 100 are upstream sweeping blades 200, and the number of upstream sweeping blades 200 is equal to that of the horizontal connecting grille bars and the two are connected to each other one by one. The air outlet grille 100 has a rectangular mesh structure. Among them, on the basis of being the horizontal grille bars 110 of the air outlet grille 100, the horizontal connecting grille bars can also serve as connecting roots to comprehensively connect and fix the roots of the corresponding upstream sweeping blades 200, thereby improving the firmness of the connection between the upstream sweeping blades 200 and the air outlet grille 100, improving the mold release convenience of the air outlet grille 100 and the upstream sweeping blades 200, and reducing the occurrence of the situation where the position of the upstream sweeping blades 200 is different from that of the horizontal grille bars 110, resulting in a large shielding area of the air outlet grille 100 and a small ventilation area. Preferably, all the horizontal grille bars 110 serve as horizontal connecting grille bars and are connected to the upstream sweeping blades 200.

[0045] Similarly, at least some of the vertical grille bars 120 serve as vertical connecting grille bars. The sweeping blades located on the downstream side of the air outlet grille 100 are downstream sweeping blades 300, and the number of downstream sweeping blades 300 is equal to that of the vertical connecting grille bars and the two are connected to each other one by one; thereby improving the firmness of the connection between the downstream sweeping blades 300 and the air outlet grille 100, improving the mold release convenience of the air outlet grille 100 and the downstream sweeping blades 300, and reducing the occurrence of the situation where the position of the downstream sweeping blades 300 is different from that of the vertical grille bars 120, resulting in a large shielding area of the air outlet grille 100 and a small ventilation area. Preferably, all the vertical grille bars 120 serve as vertical connecting grille bars and are connected to the downstream sweeping blades 300.

[0046] In this embodiment, as Figure 1 shown, a buckle portion 500 is integrally formed on the edge region of the air outlet grille 100. The buckle portion 500 is used to cooperate and engage with a fastening portion 21a provided at the air duct wall of the air conditioner. The air outlet frame 21 of the air conditioner is provided with a fastening portion 21a that matches the buckle portion 500. During installation, aligning the buckle portion 500 with the fastening portion 21a and buckling them can achieve the connection between the air outlet grille 100 and the air outlet frame 21, thereby improving the connection convenience and the connection position accuracy between the air outlet grille 100 and the air outlet frame 21; similarly, during disassembly, pulling out the buckle portion 500 from the fastening portion 21a can achieve the detachment between the air outlet grille 100 and the air outlet frame 21, thereby improving the disassembly connection degree between the air outlet grille 100 and the air outlet frame 21, and correspondingly improving the disassembly and assembly convenience of the entire air-sweeping assembly 30. Among them, the buckle portion 500 is integrally formed on the air outlet grille 100, which can ensure the processing convenience of the entire air-sweeping assembly 30, and the connection firmness between the buckle portion 500 and the air outlet grille 100 can be ensured, thereby ensuring the firmness and stability of the air-sweeping assembly 30 connected to the air outlet frame 21; specifically, the buckle portion 500 can be one of a buckle head and a card slot, and the fastening portion 21a can be the other of a buckle head and a card slot.

[0047] In this embodiment, as Figure 2 , Figure 3 and Figure 5 shown, the region where the air-sweeping blade is connected between the air outlet grille 100 and the flexible portion 420 is the connecting portion 410. In at least some of the air-sweeping blades, the thickness of the flexible portion 420 is less than that of the connecting portion 410 and the two are smoothly transitionally connected; on the one hand, the flexible portion 420 has a small thickness and a high elastic deformation ability, correspondingly ensuring the smoothness of the swinging portion 430 swinging around the flexible portion 420; on the other hand, the connecting portion 410 is smoothly connected to the flexible portion 420, which can reduce the stress generated by bending and rotating at the connection, thereby reducing the occurrence of cracking or even breaking at the connection; and the connection thickness between the connecting portion 410 and the air outlet grille 100 is relatively large, which can also ensure the connection firmness with the air outlet grille 100, and correspondingly ensure the firmness of the air-sweeping blade connected to the air outlet grille 100.

[0048] Similarly, in this embodiment, as Figure 2 , Figure 3 and Figure 5As shown, the area of the sweeping blade located on the side of the flexible part 420 away from the air outlet grille 100 is the swinging part 430. In at least part of the sweeping blades, the thickness of the flexible part 420 is smaller than that of the swinging part 430, and the two are smoothly transitionally connected. On the basis of ensuring that the flexible part 420 has a small thickness and a high elastic deformation ability, the smooth transitional connection between the swinging part 430 and the flexible part 420 can not only reduce the situation of rotational cracking at the connection, but also ensure the thickness of the swinging part 430, reduce the occurrence of its bending deformation, and ensure the effectiveness of its air guiding direction.

[0049] In this embodiment, as Figures 2 - 5 shown, through holes 421 are provided in the flexible part 420 of at least part of the sweeping blades. The provision of the through holes 421 can reduce the area of the flexible part 420, thereby improving the deformation ability of the flexible part 420, correspondingly reducing the resistance of the sweeping blade to swing around the flexible part 420, improving the smoothness of the sweeping blade to swing around the flexible part 420, and at the same time reducing the driving load of the upstream driving assembly 40 and the downstream driving assembly 50.

[0050] Specifically, in this embodiment, as Figure 5As shown, at least part of the through hole 421 includes a middle extension section 421a and two end extension sections 421b, the extension direction of the middle extension section 421a is consistent with the extension direction of the corresponding flexible portion 420, and the two end extension sections 421b are connected to the two ends of the middle extension section 421a one by one and both extend away from the air outlet grille 100. The flexible portion 420 serves as a swing axis for the wind sweeping blade to swing. When there is one through hole 421, two flexible connecting arms 422 are formed between the end extension section 421b and the corresponding side edge of the flexible portion 420; when there are multiple through holes 421 and they are arranged at intervals along the width direction of the flexible portion 420, flexible connecting arms 422 can be formed between the end extension sections 421b on both sides and the corresponding side edge of the flexible portion 420 and between the two adjacent end extension sections 421b on the inner side. The area of ​​the wind sweeping blade located on the side of the flexible connecting arm 422, the end extension section 421b and the middle extension section 421a away from the air outlet grille 100 serves as the swing portion 430. Then, the sum of the widths of each flexible connecting arm 422 along the width direction of the air outlet grille 100 is the effective length of the swing axis, and the length of each flexible connecting arm 422 along the direction away from the air outlet grille 100 is the effective elastic bending length. Among them, on the one hand, it is set The central extension section 421a extends along the width direction of the air outlet grille 100. On the basis of ensuring the connecting function of the flexible portion 420, it can effectively shorten the effective length of the swing shaft, and correspondingly effectively improve the flexible deformation capacity of the swing shaft, improve the smoothness of the swing of the wind sweeping blade around the swing shaft, and reduce the driving load of the upstream drive component 40 and the downstream drive component 50; on the other hand, the end extension section 421b is set, and the area between the two is still used as the effective swinging area of ​​the wind sweeping blade. On the basis of ensuring the extension length of the wind sweeping blade away from the air outlet grille 100, the length of the flexible connecting arm 422 can be increased, that is, the effective elastic bending length is increased, so as to further improve the flexible deformation capacity of the flexible portion 420 on the basis of ensuring the wind guiding area of ​​the wind sweeping blade, improve the smoothness of the swing of the wind sweeping blade around the flexible connecting arm 422, and reduce the driving load of the upstream drive component 40 and the downstream drive component 50.

[0051] Preferably, the flexible portion 420 of each wind sweeping blade is provided with a through hole 421, and when the wind sweeping blades located on the same side are arranged in rows along the length direction of the air outlet grille 100, such as the horizontal swing blades of a vertical air conditioner, the through holes 421 are in the form of the above-mentioned middle extension section 421a and the two end extension sections 421b; when the wind sweeping blades located on the same side are arranged in rows along the width direction of the air outlet grille 100, such as the longitudinal swing blades of a vertical air conditioner, the through holes 421 can be strip holes, and the extension direction of the strip holes is consistent with the length direction of the air outlet grille 100.

[0052] Specifically, in this embodiment, Figure 5As shown, there are at least two through holes 421. Along the width direction of the air outlet grille 100, the through holes 421 are arranged at intervals, and among the end extension segments 421b of each through hole 421, the two located on both sides are edge extension segments, and the rest are internal extension segments. The extension length of the internal extension segments is greater than that of the edge extension segments. The length of the flexible connection arm 422 formed between the two edge extension segments located on both sides in the width direction and the corresponding edge of the flexible part 420 is smaller to ensure the connection stability of the flexible part 420 to the outer area thereof; the length of the flexible connection arm 422 formed between the adjacent internal extension segments of two adjacent through holes 421 is larger to further improve its flexible deformation ability, thereby further improving the swinging smoothness of the air-sweeping blade around the flexible connection arm 422 and reducing the driving load of the upstream driving assembly 40 and the downstream driving assembly 50.
