Technical Field

[0001] This utility model relates to the field of air conditioning technology, specifically to a modular splicing air guide plate and its air guide assembly, and an air conditioner. Background Technology

[0002] In order to change the airflow angle of its air outlet, an air conditioner will set a guide structure at the air outlet. For example, CN207610344U discloses an air guide structure for an air conditioner. The air guide structure includes: a fixed plate, which is fixedly connected to the inner wall of the air outlet; a rotating plate, which is movably connected to the inner wall of the air outlet; and at least one air guide vane. Each air guide vane includes a first end fixedly connected to the fixed plate and a second end fixedly connected to the rotating plate. A through groove is provided between the first end and the second end, passing through both sides of the air guide vane.

[0003] The air guide structure mentioned above adjusts the air guide angle by causing the air guide plate to bend and deform under the action of external force. This results in high requirements for the plasticity of the air guide plate and the air guide plate is prone to damage due to bending deformation during long-term use. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a combined splicing air guide plate and its air guide assembly and air conditioner, so as to solve the problems in the existing technology, which require high plasticity of the air guide plate when adjusting the air guide angle and the air guide plate is prone to damage due to bending deformation during long-term use.

[0005] To achieve the above objectives, the first aspect of this utility model adopts the following technical solution: a combined splicing air guide plate, including an air guide fixing plate for fixedly arranged inside the air duct of an air conditioner and an air guide moving plate rotatably connected to the air guide fixing plate, wherein the air guide moving plate is set inside the air outlet of the air conditioner and adjusts the air outlet direction by rotating.

[0006] The second aspect of this utility model adopts the following technical solution: an air guide assembly, including a connecting rod, a bracket fixedly installed in the air outlet of an air conditioner, and a plurality of combined spliced ​​air guide plates as described in the first aspect of this utility model; the air guide fixing plates in the plurality of combined spliced ​​air guide plates are all fixedly connected to the bracket and arranged at intervals along the length direction of the bracket, and the free ends of the air guide moving plates in the plurality of combined spliced ​​air guide plates are all connected to the connecting rod.

[0007] The third aspect of this utility model adopts the following technical solution: an air conditioner, including an air guide component as described in the second aspect of this utility model.

[0008] Compared with the prior art, the present invention has the following beneficial effects: This modular splicing air guide plate mainly consists of a fixed air guide plate and a rotating air guide plate connected to it. The fixed air guide plate is fixed inside the air duct of the air conditioner to reduce turbulence. Since the rotating air guide plate is rotatably connected to the fixed air guide plate, it is rotatably arranged inside the air outlet of the air conditioner to determine the direction of airflow. Since the air guide plate does not need to bend or deform to change the direction of airflow, the plasticity requirements for the air guide plate are relatively low and there is no problem of damage caused by bending deformation.

[0010] The reference numerals in the accompanying drawings include: air guide fixing plate 1, connecting column 11, annular connecting groove section 111, clearance port 112, air guide moving plate 2, connecting bayonet 21, connecting rod 3, bracket 4, first connecting piece 5, limiting connecting column 51, connecting limiting hole 52, deformation adjustment hole 53, second connecting piece 6, elastic buckle 61, driver 7, and transmission shaft sleeve 8. Detailed Implementation

[0011] The present invention will be further described in detail below through specific embodiments: like Figure 1 As shown in the figure, this utility model embodiment proposes a combined splicing air guide plate, including an air guide fixing plate 1 for fixedly arranged inside the air duct of the air conditioner and an air guide moving plate 2 rotatably connected to the air guide fixing plate 1. The air guide moving plate 2 is set in the air outlet of the air conditioner and adjusts the air outlet direction by rotating.

[0012] This modular splicing air guide plate mainly includes an air guide fixed plate 1 and an air guide moving plate 2 rotatably connected to it. The air guide fixed plate 1 is fixed in the air duct of the air conditioner to reduce turbulence. Since the air guide moving plate 2 is rotatably connected to the air guide fixed plate 1, the air guide moving plate 2 is rotatably arranged in the air outlet of the air conditioner to determine the air blowing direction of the air outlet. Since the air guide plate does not need to bend or deform to change the air blowing direction, the plasticity requirement of the air guide plate is relatively low and there is no problem of damage caused by bending deformation.

[0013] In order to enable the air guide moving plate 2 and the air guide fixing plate 1 to be quickly and stably connected, in this embodiment, a plurality of connecting slots 21 are arranged at intervals along the length direction on one end of the air guide moving plate 2, and a connecting post 11 is formed along the length direction on one end of the air guide fixing plate 1. A plurality of connecting clearance portions are arranged at intervals along the length direction on the connecting post 11, which are rotatably engaged with the plurality of connecting slots 21 one by one.

[0014] Each of the aforementioned connection clearance portions includes an annular connection groove segment 111 and a clearance opening 112. The annular connection groove segment 111 is formed on the connecting column 11 by being arranged along its circumferential direction and recessed inward. The corresponding connection latch 21 is fitted onto the annular connection groove segment 111. The clearance opening 112 is opened on the air guide moving plate 2 and provides clearance space when the connection latch 21 rotates.

[0015] Specifically, in this embodiment, the number of connecting slots 21 is shown as two, so there are also two annular connecting groove segments 111 formed on the connecting post 11, and correspondingly, there are also two clearance openings 112. The connecting slot 21 is specifically an Ω-shaped slot. The Ω-shaped slot fits into the annular connecting groove segment 111 to make the rotational contact area between the air guide moving plate 2 and the air guide fixed plate 1 relatively small, thereby reducing the frictional resistance encountered during rotation. When the air guide moving plate 2 rotates, the connecting slot 21 rotates relative to the annular connecting groove segment 111, and both ends of the connecting slot 21 either enter into or exit from the clearance opening 112, preventing the rotation of the connecting slot 21 relative to the annular connecting groove segment 111 from being obstructed.

[0016] Meanwhile, during the rotation of the air guide vane 2, a small amount of dust on it can be discharged into the annular connecting groove section 111 for collection. Because the amount of dust is very small, it will not affect the rotation of the air guide vane 2. After prolonged use, the connecting bayonet 21 can be disconnected from the annular connecting groove section 111 to clean the dust collected in the annular connecting groove section 111.

[0017] The above-mentioned modular air guide vanes are applied to air guide components, such as... Figure 2 , Figure 3 as well as Figure 4 As shown, according to another embodiment of the present invention, the air guide assembly includes a connecting rod 3, a bracket 4 fixedly installed in the air conditioner outlet, and a plurality of combined splicing air guide plates as described in the above embodiment; the air guide fixing plates 1 in the plurality of combined splicing air guide plates are all fixedly connected to the bracket 4 and arranged at intervals along the length direction of the bracket 4, and the free ends of the air guide moving plates 2 in the plurality of combined splicing air guide plates are all connected to the connecting rod 3.

[0018] Specifically, the fixed air guide plates 1 of the combined spliced ​​air guide plates are arranged at intervals in the air duct of the air conditioner, and the moving air guide plates 2 of the combined spliced ​​air guide plates are arranged at intervals in the air outlet of the air conditioner. The cooperation of the fixed air guide plates 1 reduces the generation of turbulence. The moving linkage 3 adjusts the rotation of the moving air guide plates 2 at the same time. The moving air guide plates 2 cooperate to change the air outlet direction.

[0019] First, in order to enable the air guide vane 2 to be quickly and stably connected to the connecting rod 3, the free end of each air guide vane 2 is connected to the connecting rod 3 through a first connector 5. Each first connector 5 includes a limiting connecting post 51 and a connecting limiting hole 52. The limiting connecting post 51 is connected to the free end of the corresponding air guide vane 2. The connecting limiting hole 52 is opened on the connecting rod 3 and one end of the limiting connecting post 51 is inserted into the connecting limiting hole 52 for movable connection. The limiting connecting column 51 includes a movable connecting section and a guide limiting section. One end of the movable connecting section is fixedly connected to the free end of the air guide moving plate 2. The guide limiting section has a guide cone surface that passes through the connecting limiting hole 52 and forms a limiting step that prevents it from falling out of the connecting limiting hole 52 after it is connected to the other end of the movable connecting section.

[0020] In this embodiment, the movable connecting section is cylindrical, and the guide limiting section is conical. The diameter of the larger end of the guide limiting section is larger than the diameter of the movable connecting section, so that a limiting step is formed between the movable connecting section and the guide limiting section. The guide limiting section is designed to guide the limiting connecting post 51 during its insertion into the connecting limiting hole 52. After the movable connecting section passes into the connecting limiting hole 52 and the guide limiting section passes out of the connecting limiting hole 52, the movable connecting section adapts to the connecting limiting hole 52 for movable connection. The limiting step prevents the limiting connecting post 51 from disengaging from the connecting limiting hole 52, so that the air guide moving plate 2 and the connecting rod 3 are stably connected. Here, an assembly notch is formed on one side of the free end of the air guide moving plate 2. The limiting connecting post 51 is set at the opening of the assembly notch and arranged along the width direction of the opening, so that when the air guide moving plate 2 is connected to the connecting rod 3, the connecting rod 3 is partially movable within the assembly notch, and then the limiting connecting post 51 connects to the connecting limiting hole 52 for reasonable arrangement.

[0021] During the process of the guide limit section passing through the connecting limit hole 52, the connecting limit hole 52 will deform. In order to increase the deformation capacity of the connecting rod 3 during this process and avoid damage, a deformation adjustment hole 53 is provided on one side of the connecting limit hole 52. The deformation adjustment hole 53 provides clearance space for the deformation of the connecting limit hole 52, ensuring that the air guide moving plate 2 and the connecting rod 3 are connected more safely.

[0022] Secondly, in order to enable the air guide fixing plate 1 to be quickly and stably connected to the bracket 4, each air guide fixing plate 1 is connected to the bracket 4 by a second connector 6. Each second connector 6 includes an elastic buckle 61 and an assembly hole. The elastic buckle 61 is fixedly connected to the corresponding air guide fixing plate 1. The assembly hole is opened on the bracket 4 and the elastic buckle 61 is elastically engaged in the assembly hole.

[0023] Here, the elastic buckle 61 is specifically connected to one end of the connecting post 11 and is composed of two buckle pieces arranged in opposite directions and at intervals. One end of the two buckle pieces is connected to the connecting post 11 and the other end has a limiting head. During the process of the elastic buckle 61 being elastically engaged in the assembly hole, the two limiting heads are inserted into the assembly hole for guidance and to squeeze the two buckle pieces to move in opposite directions until the two limiting heads pass through the assembly hole and the two buckle pieces are elastically engaged in the assembly hole. The two limiting heads cooperate to prevent the elastic buckle 61 from disengaging from the assembly hole.

[0024] To facilitate easier and faster adjustment of the airflow direction, the air guide assembly further includes a drive unit for moving the connecting rod 3. The drive unit includes a driver 7 and a transmission shaft sleeve 8. The driver 7 is fixedly mounted on the bracket 4; the transmission shaft sleeve 8 connects the driver 7 and the connecting rod 3. In this embodiment, the drive unit can be a stepper motor, which is fixedly mounted on the side of the bracket 4 away from the combined spliced ​​air guide plates. The stepper motor passes through a through hole in the bracket 4 and is connected to one end of the transmission shaft sleeve 8. The other end of the transmission shaft sleeve 8 is connected to one end of the connecting rod 3. When the stepper motor is activated, it drives the connecting rod 3 to move via the transmission shaft sleeve 8, thereby simultaneously driving several air guide plates 2 to rotate, thus changing the airflow direction of the air outlet.

[0025] The connecting rod 3 and the transmission shaft sleeve 8 are also connected by the first connecting member 5.

[0026] Applying the above-mentioned air guiding components to air conditioners, such as... Figure 5 As shown, according to another embodiment of the present invention, the air conditioner includes the air guide assembly as described in the above embodiment. The air guide assembly is installed in the air outlet of the air conditioner. On the one hand, it reduces the generation of turbulence by cooperating with a plurality of air guide fixing plates 1, and on the other hand, it changes the air outlet direction by cooperating with a plurality of air guide moving plates 2.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
