Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to a screw-driven swing blade device, an air guide device and an air conditioner. Background Art

[0002] In the existing air duct components, the swing of the sweeping blades is generally achieved by driving the active sweeping blades to swing through a motor, and the active sweeping blades are connected to the other sweeping blades through a connecting rod. During the rotation process, only when the motor drives the active sweeping blades to rotate to a certain position can it drive the connecting rod to drive, and then drive the other sweeping blades to swing, and the transmission effect is poor.

[0003] In addition, the assembly of the sweeping blades and the connecting rod is difficult, and the connecting rod needs to be clamped and connected to each sweeping blade, which makes the assembly inefficient. In addition, when the connecting rod is separated from the sweeping blade during the air duct cleaning process, disassembly and installation are very troublesome. Summary of the invention

[0004] In response to the above technical problems, the present invention discloses a screw-driven swing blade device, an air guide device and an air conditioner. A screw with a threaded portion is provided, and a driving device can drive the screw to rotate. A mounting groove is provided on the wind sweeping blade, and the threaded portion of the screw extends into the mounting groove. When the screw rotates under the action of the driving device, it drives the wind sweeping blade to swing, and the left and right swing of the wind sweeping blade is realized by the forward and reverse rotation of the screw.

[0005] In order to solve the above problems, the present invention discloses a screw-driven swing blade device, including multiple wind-sweeping blades and a screw. A mounting groove is arranged on each of the wind-sweeping blades. The screw includes a threaded portion, and the screw can pass through the multiple wind-sweeping blades in sequence. The threaded portion is meshingly connected with the mounting groove.

[0006] The setting is connected to the wind sweeping blades through the meshing connection of the screw rod, has a reasonable structure, is quick to install, has a stable connection, realizes instant transmission, and improves the transmission efficiency of the screw rod driving the wind sweeping blades to swing when the swing blade device is working.

[0007] Furthermore, the mounting groove is set as an open groove on the wind sweeping blade, and an extension line of the mounting groove is L1. A rotating shaft is set at one end of the wind sweeping blade, and the wind sweeping blade can swing left and right along the rotating shaft. The center line of the rotating shaft is L2, and the angle between L1 and L2 is β, and the value range of β is 60° to 120°.

[0008] Furthermore, L1 and L2 are arranged perpendicularly, and β is 90°.

[0009] This arrangement enables the screw rod to directly enter from the open end of the installation groove during installation, thereby achieving high installation efficiency. The wind sweeping blade swings left and right along the center line L2 of the rotating shaft, and the extension line of the installation groove L1 is set at an angle β to the center line L2 of the rotating shaft, especially L1 is set perpendicular to L2, thereby ensuring the reliability of the screw rod driving the wind sweeping blade to swing and the stability of the transmission.

[0010] Furthermore, the transmission plate connected to the mounting groove and the threaded portion of the screw rod is arranged in an arc shape.

[0011] This arrangement further enables the threaded portion of the screw rod to remain engaged with the transmission plate of the mounting groove when the screw rod drives the wind sweeping blade to swing and the screw rod slides in the mounting groove, thereby further improving the reliability of the screw rod driving the wind sweeping blade to swing.

[0012] Furthermore, the pitch between two adjacent threads of the threaded portion is H, the thickness of the plate at the portion in the mounting groove that meshes with the threaded portion is M, and H≥M.

[0013] This arrangement ensures that the width of the connection of the mounting groove on the wind sweeping blade can only occupy one thread gap of the screw rod, that is, the thickness of the transmission plate on the mounting groove is smaller than the spacing between two adjacent threads on the threaded portion of the screw rod, further improving the reliability of the screw rod driving the wind sweeping blade to move immediately.

[0014] The present invention also discloses an air guide device, including an air outlet component and a swing blade device, wherein the swing blade device is the swing blade device as described above, an air outlet is arranged on the air outlet component, the swing blade device is detachably fixed in the air outlet, and the swing blade device swings left and right under the action of a driving device.

[0015] The air guide device described in the present invention, by setting up the swing blade device as described above, has a simple structure, reliable transmission, and convenient processing and manufacturing. The previous processing mold can be directly used to reduce production costs and facilitate maintenance and assembly of the swing blade assembly.

[0016] Furthermore, the driving device comprises a driving motor, and an output shaft of the driving motor is coaxially arranged with the lead screw.

[0017] The present application adopts a driving motor to axially drive the screw to rotate, and there is no need to add a crank to transmit power. The torque is large, and a smaller motor can be driven. The driving motor and the screw are arranged coaxially to save space and facilitate assembly.

[0018] Furthermore, a first connecting portion is provided at one end of the screw rod, and the first connecting portion is transmission-connected to the output shaft via a converter.

[0019] This arrangement eliminates relative motion between the motor output end and the lead screw, reducing power loss. At the same time, an adapter is used to perform an axial transmission connection between the output shaft and the lead screw. When adapting to different machine models, only the adapter structure needs to be replaced, thereby improving the universality of the connection.

[0020] Furthermore, the adapter includes a plate body, and a second connecting portion and a third connecting portion are respectively arranged on both sides of the plate body, and the second connecting portion and the third connecting portion are plug-connected with the end of the screw rod and the end of the output shaft respectively.

[0021] The arrangement discloses a transmission connection mode between the adapter and the lead screw and the output shaft of the driving motor, which is convenient and quick to install, has stable and reliable transmission, and is easy to process and produce, thereby reducing production costs.

[0022] Furthermore, a first connecting portion is provided at one end of the screw rod, and the first connecting portion is directly coaxially connected to the output shaft.

[0023] This arrangement directly connects the lead screw to the output shaft of the drive motor for coaxial transmission, reduces the number of intermediate adapters, saves parts, and reduces production costs.

[0024] Furthermore, a support portion is provided in the air outlet, and the swing blade device includes a first swing blade assembly and a second swing blade assembly, and the first swing blade assembly and the second swing blade assembly are respectively provided on both sides of the support portion.

[0025] This arrangement does not require each wind sweeping blade to be fixed in the air outlet, thus saving assembly time, reducing assembly difficulty, and facilitating maintenance and replacement of the swing blade device.

[0026] Furthermore, the first swing blade assembly includes a plurality of wind-sweeping blades and a first connecting plate, one end of the wind-sweeping blade on the first swing blade assembly is connected to the first connecting plate via a wind-sweeping blade rotating shaft, the second swing blade assembly includes a plurality of wind-sweeping blades and a second connecting plate, one end of the wind-sweeping blade on the second swing blade assembly is connected to the second connecting plate via a wind-sweeping blade rotating shaft, and the first connecting plate and the second connecting plate are detachably fixed in the air outlet.

[0027] This arrangement arranges the wind sweeping blades driven by the connecting rod on both sides of the support part on the first connecting plate and the second connecting plate respectively. On the one hand, it avoids the support part in the air outlet, and on the other hand, it reduces the changes to the air outlet frame structure. The production can be completed by using the original mold, which reduces the production cost and improves the applicability of the present invention.

[0028] Furthermore, the first connecting plate and the second connecting plate are integrally formed, and the wind sweeping blades driven by the screw rod on both sides of the support portion are arranged on the same mounting plate.

[0029] This arrangement further improves the assembly efficiency of the swing blade device. At the same time, when the blades on the left and right sides of the support part are made into one piece, it is also convenient to install the screw rod in one go, thereby improving the convenience of assembly.

[0030] The air guide device described in the present invention has a simple structure, and is convenient for simultaneously assembling the screw rod and multiple wind sweeping blades on both sides of the support part, which greatly improves the efficiency of installation and removal.
