In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0038] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or can communicate with each other; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] The present invention is described below with reference to specific embodiments in conjunction with the accompanying drawings.

[0040] First combine Figure 1-Figure 9 The wind guiding device 100 according to the embodiment of the present invention is described.

[0041] like Figure 1-Figure 9 As shown, the air guide device 100 of the embodiment of the present invention may include an air guide portion (for example, a first air guide portion 11, which is only for exemplary purposes) and a switch device 7. The air-conditioning system has an air outlet 300, and the hot air or cold air blown out of the air-conditioning system can be blown into the room through the air outlet 300.

[0042] When the air conditioning system stops working, the switch device 7 can be driven to move to close the air outlet 300. At this time, the switch device 7 can prevent external dust and other debris from entering the air conditioning system through the air outlet 300. When the air conditioning system starts working, the switch device 7 can be driven to open the air outlet 300, and then the airflow blown out from the air outlet 300 of the air conditioning system is guided by the air guide part. One side of the air guide part forms an airflow guide surface 13 for guiding the airflow from the air outlet 300 to the room. The switch device 7 can be stored in the air outlet 300 to avoid the switch device 7 occupying the external space.

[0043] According to the air guide device 100 of the embodiment of the present invention, by separating the air guide portion from the switch device 7, the air guide portion can be designed separately, so that the curvature and other parameters of the air guide portion can be designed completely according to the air outlet requirements, ensuring that the air conditioning system has a good air outlet effect, thereby ensuring the temperature adjustment effect of the air conditioning system. At the same time, the switch device 7 can be designed separately (for example, when the air conditioning system stops working, the curvature of the switch device 7 is set to be tangent to the shell of the air conditioning system, which is only a non-limiting exemplary description), so that when the air conditioning system stops working, the switch device 7 is guaranteed to completely close the air outlet 300.

[0044] Specifically, Figure 1-Figure 4 As shown, the switch device 7 is located radially outside the air guide relative to the rotation axis of the air guide. Thus, the switch device 7 can avoid the shutter wind sweeping structure 41 and other components inside the air guide. At the same time, the switch device 7 can avoid blocking the rotation of the air guide, so that the adjustment range of the air guide angle of the air guide is larger, and when the switch device 7 closes the air outlet 300, the air guide can be covered inside the air outlet 300 to protect the air guide.

[0045] Specifically, Figure 2-Figure 4 As shown, the switch device 7 can be rotated to open or close the air outlet 300. In other words, the switch device 7 can be rotated along the length direction of the air outlet as an axis. The switch device 7 can be rotated to an open position (for example, rotated to the surface inside the air outlet) to open the air outlet 300, and the switch device 7 can also be rotated to a closed position to close the air outlet 300.

[0046] The air guide device 100 further includes: a driving device 2, which is used to drive the air guide portion and / or the switch device. In some embodiments, the driving device 2 can only drive the air guide portion to rotate so that the air guide portion has different air guide angles. In other embodiments, the driving device 2 can only drive the switch device to rotate so that the air outlet is opened or closed. In still other embodiments, the driving device 2 can simultaneously drive the air guide portion and the switch device 7 to rotate, thereby saving layout space.

[0047] More specifically, the drive device 2 has a first drive shaft and a second drive shaft. The drive device 2 can output power to the air guide part through the first drive shaft to rotate the air guide part. The drive device 2 can output power to the switch device 7 through the second drive shaft to rotate the switch device 7.

[0048] Specifically, Figure 6 , Figure 8 and Fig. 9 As shown, the air guide portion is provided with a rectifying grille 5 on at least one side along the air flow direction. The rectifying grille 5 can rectify the airflow passing through the air guide portion, so that the airflow is blown more evenly from the air outlet 300 to the room, thereby improving the heat exchange effect of the air conditioning system. In addition, the rectifying grille 5 can rotate with the air guide portion, so that when the air guide portion rotates to different angles to guide the airflow to different directions, the rectifying grille 5 can also rectify the airflow blown out in that direction, and the rectifying effect is better.

[0049] Specifically, Figure 2-Figure 4 As shown, there are multiple air guides (for example, a first air guide 11 and a second air guide 12, which are only exemplary), each of which is located at a different position of the air outlet 300, and the air guide can be rotated to change the guiding angle of the air guide to the airflow. By rotating different air guides to different angles, the airflow blown out from different positions of the air outlet 300 corresponding to the air guide can be guided to different directions, meeting more blowing requirements of the air conditioning system.

[0050] Specifically, Figure 1-Figure 4 As shown, the air outlet 300 is located near the bottom plate 200 of the air conditioning system.

[0051] In some optional embodiments of the present invention, multiple air guides are sequentially arranged along the length direction of the air outlet 300 (i.e., along the direction of the rotation axis of the air guide). Thus, multiple air guides can guide the airflow blown out from different positions along the length direction of the air outlet 300 to different directions, and the blowing angle is free, which can meet the air conditioning system's demand for blowing airflow in multiple directions at the same time.

[0052] In some specific embodiments, there are two air guides, which are arranged along the length direction of the air outlet 300. A driving device 2 is respectively arranged at both ends of the length direction of the air outlet 300, and each driving device 2 is respectively used to drive the rotation of an air guide adjacent to the driving device 2. Specifically, the driving device 2 is a motor, and the motor output shaft of the driving device 2 can be connected to the air guide to drive the air guide to rotate.

[0053] In other specific embodiments, there are three or more air guides, and there is a mounting portion between two adjacent air guides along the length direction of the air outlet 300, and the mounting portion is fixed on the air conditioning system (for example, fixed to the bottom plate 200 of the air conditioning system), and each mounting portion is provided with a driving device 2, and each driving device 2 is used to drive at least one air guide to rotate. For example, each driving device 2 can drive the air guides on one or both sides adjacent to it to rotate.

[0054] In other specific embodiments, a plurality of air guides may also be arranged in sequence along the width direction of the air outlet 300 (i.e., along the circumferential direction of the rotation axis of the air guide). Thus, by rotating different air guides, the opening angle between two adjacent air guides can be changed, and the airflow is blown into the room through between two adjacent air guides. Compared with the prior art in which only one air guide is provided, this arrangement can make the airflow of the air outlet 300 have more blowing angles and a larger blowing area, further meeting the different needs of personnel for blowing airflow. In addition, when only one air guide is required for blowing, the other air guides can close the air outlet 300 to prevent dust from entering the air outlet 300.

[0055] like Fig. 9 As shown, at least one end of the air outlet 300 in the length direction is provided with a driving device 2 for driving the air guide part to rotate. The driving device 2 can be a motor, and the output shaft of the motor can be connected to the air guide part to drive the air guide part to rotate.

[0056] Specifically, Figure 1 , Figure 8 As shown, the air guide device 100 is respectively provided with end covers 3 at both ends of the length direction of the air outlet 300. The end cover 3 can be a cylindrical cover with an opening at one axial end. The end cover 3 can block the air guide part at both axial ends to prevent external dust from entering the air outlet 300 from the axial ends of the air guide part.

[0057] An installation space 31 is provided in the end cover 3 , and a driving device 2 for driving the air guide portion to rotate is provided in the installation space 31 , so that the end cover 3 protects the driving device 2 for driving the air guide portion to rotate.

[0058] In some specific embodiments, Figure 8 As shown, the end cover 3 is fixed to at least one air guide portion, so that the end cover 3 can rotate together with the air guide portion. The end cover 3 is provided with an avoidance gap 32 for avoiding the driving device 2 when rotating with the air guide portion. The avoidance gap 32 can be an opening on the side wall of the end cover 3. The driving device 2 is fixed in the air-conditioning system (for example, the driving device 2 is fixed to the base plate 200 of the air-conditioning system) and does not rotate with the end cover 3. When the end cover 3 rotates with the air guide portion, the end cover 3 rotates relative to the driving device 2, and the avoidance gap 32 can avoid the driving device 2.

[0059] In some other specific embodiments, Figure 1 As shown, the end cover 3 is fixed in the air conditioning system. At this time, the end cover 3 and the driving device 2 are both fixed in the air conditioning system (for example, the end cover 3 and the driving device 2 are both fixed to the bottom plate 200 of the air conditioning system), and the air guide portion rotates relative to the end cover 3.

[0060] In some specific embodiments, Figure 7-Figure 9 As shown, at least one air guide is installed with a louver wind sweeping structure 41, so that the louver wind sweeping structure 41 can rotate together with the air guide, and the louver wind sweeping structure 41 does not need to be arranged in the air outlet 300, reducing the space occupied by the louver wind sweeping structure 41 inside the air conditioning system. The louver wind sweeping structure 41 has a plurality of wind sweeping blades 411, and the plurality of wind sweeping blades 411 are arranged at intervals along the rotation axis of the air guide, and the plurality of wind sweeping blades 411 can swing along the rotation axis direction of the air guide. Therefore, when the airflow blown out from the air outlet 300 passes through the air guide, the plurality of wind sweeping blades 411 can further change the direction of the airflow to meet the different blowing needs of users.

[0061] like Figure 7 and Fig. 9 As shown, the air guide device 100 further includes: a louver driving structure 43 and a louver transmission structure 42. The louver driving structure 43 is suitable for swinging a plurality of wind sweeping blades 411 of the louver wind sweeping structure 41 along the rotation axis of the air guide portion through the louver transmission structure 42. In some embodiments, when the driving device 2 drives the air guide portion to rotate, the wind sweeping blades 411 rotate together with the air guide portion. At the same time, the louver driving structure 43 drives the wind sweeping blades 411 to swing along the rotation axis direction of the air guide portion. Thus, the air guide device 100 can continuously guide the airflow blown out from the air outlet 300 to multiple directions, so that the airflow is blown evenly in the room, thereby improving the heat exchange effect of the air conditioning system.

[0062] In some specific embodiments, Figure 7 and Fig. 9 As shown, a through hole 412 is provided at the bottom of the plurality of wind sweeping blades 411 (i.e., the side of the wind sweeping blades 411 facing the air guide portion), and the shutter transmission structure 42 includes: a pull rod 421 and a transition transmission rod 422, the pull rod 421 is suitable for passing through the plurality of through holes 412, and a limit hole 424 is provided at the end of the pull rod 421, and one end of the transition transmission rod 422 is suitable for being sleeved on the output shaft of the shutter driving structure 43, and the transition transmission rod 422 is suitable for passing through the limit hole 424, and the limit hole 424 can be an oblong hole. The output shaft of the shutter driving structure 43 can drive the transition transmission rod 422 to rotate, so that the transition transmission rod 422 moves in the limit hole 424 and drives the pull rod 421 to move along the arrangement direction of the plurality of wind sweeping blades 411 (i.e., the axial direction of the air guide portion). It can be understood that the pull rod 421 can move in both directions in the arrangement direction of the wind sweeping blades 411.

[0063] like Figure 7 As shown, a plurality of push protrusions 423 are provided at intervals in the length direction of the pull rod 421, and the push protrusions 423 correspond to one wind sweeping blade 411 respectively. For example, a push protrusion 423 is provided between every two wind sweeping blades 411, and the volume or height of the push protrusion 423 is greater than the through hole 412 to prevent the push protrusion 423 from passing through the through hole 412 when the pull rod 421 moves. When the pull rod 421 moves along the arrangement direction of the plurality of wind sweeping blades 411, each push protrusion 423 is clamped at the through hole 412 of a wind sweeping blade 411 and pushes the wind sweeping blade 411 to swing along the moving direction of the pull rod 421. The shutter driving structure 43 can make the wind sweeping blade 411 swing to different angles by driving the position change of the pull rod 421. Specifically, the shutter driving structure 43 can be a motor.

[0064] In some specific embodiments, the shutter drive structure 43 and the drive device 2 can be fixed in the air conditioning system (for example, fixed to the bottom plate 200), and the shutter drive structure 43 and the drive device 2 can be installed in the installation cavity 17. Thus, the shutter drive structure 43 can avoid the airflow guide surface 13, so that the airflow can be blown into the room through the airflow guide surface 13.

[0065] Specifically, an integrated motor 6 is provided in the mounting cavity 17 of the end cover 3. The integrated motor 6 has an air guide output shaft and a louver output shaft. The air guide output shaft forms a driving device 2, and the louver output shaft forms a louver driving structure 43. Thus, the integrated motor 6 can simultaneously output power for the rotation of the air guide and the swing of the wind sweeping blades 411, which is more integrated and easier to arrange.

[0066] More specifically, the free end of the transition transmission rod 422 after passing through the limiting hole 424 is provided with a bending limiting section suitable for limiting the pull rod 421. The bending limiting section can prevent the transition transmission rod 422 from escaping from the limiting hole 424 when the pull rod 421 moves along the arrangement direction of the multiple wind sweeping blades 411.

[0067] Alternatively, if Figure 5 , Figure 6 and Fig. 9 As shown, the switch device 7 and each air guide part include an arc plate, the surface of the arc plate forms an airflow guide surface 13, and the cylindrical axis where the arc plate is located is the rotation axis of the air guide part, thereby making the rotation process of the air guide part more stable and effectively increasing the air guide angle of the air guide part. At least one end of the axial direction of the arc plate is provided with a connecting plate 14 suitable for rotating with the driving device 2, thereby enabling the driving device 2 to drive the air guide part to rotate.

[0068] like Figure 5As shown, the air guide portion includes: an inner air guide plate 15 and an outer air guide plate 16, the inner air guide plate 15 and the outer air guide plate 16 are connected, and a mounting cavity 17 is formed between the inner air guide plate 15 and the outer air guide plate 16, and a heat preservation material is arranged in the mounting cavity 17, and the heat preservation material can be a sponge, thereby, the heat preservation performance of the air guide portion is strong, and condensation water is prevented from being generated when the airflow passes through the air guide portion and causing the condensation water to flow back to the air outlet 300. The side surface of the inner air guide plate 15 away from the mounting cavity 17 forms an airflow guiding surface 13.

[0069] Specifically, Figure 5 As shown, the surface of the inner air guide plate 15 facing the installation cavity 17 and / or the surface of the outer air guide plate 16 facing the installation cavity 17 are provided with a limiting protrusion 18 for positioning the thermal insulation material. The limiting protrusion 18 can firmly fix the thermal insulation material in the installation cavity 17.

[0070] like Figure 7 As shown, the shutter wind sweeping structure 41 is installed at the airflow guiding surface 13. The airflow guiding surface 13 is provided with a mounting hole 131 communicating with the mounting cavity 17. The portion of the shutter driving structure 43 is adapted to extend into the mounting cavity 17 from the mounting hole 131. The portion of the shutter driving structure 43 extending out of the airflow guiding surface 13 is installed with the shutter wind sweeping structure 41 through the shutter transmission structure 42. Thus, the arrangement space of the shutter driving structure 43 can be saved, and the shutter driving structure 43 can be prevented from being too large at the airflow guiding surface 13 to hinder the airflow.

[0071] In some specific embodiments, the inner air guide plate 15, the outer air guide plate 16 and the sweeping blade 411 are an integrally formed part. As a result, the overall strength of the air guide portion is high and the installation is convenient. More specifically, the sweeping blade 411 is made of a flexible part (for example, a plastic part, the inner air guide plate 15, the outer air guide plate 16 and the sweeping blade 411 are an integrally formed injection molded part), so that the sweeping blade 411 is easy to deform relative to the inner air guide plate 15, and the sweeping blade 411 is easy to swing.

[0072] In some other specific embodiments, the inner air guide plate 15, the outer air guide plate 16 and the wind sweeping blade 411 can be manufactured separately and then fixed by bonding or other methods, thereby facilitating the manufacture of the air guide portion.

[0073] More specifically, Figure 6 As shown, the air guide portion is provided with rectifying grilles 5 on both sides along the airflow direction, and the rectifying holes 53 of the rectifying grilles 5 on both sides of the airflow direction are opposite to each other. Thus, the airflow can blow through the opposite rectifying holes 53 in sequence, so that the rectifying holes 53 on both sides can better rectify the airflow blowing out of the air outlet 300, thereby improving the heat exchange effect of the air conditioning system.

[0074] More specifically, Figure 6As shown, the rectifying grid 5 has a transverse rectifying plate 51 and a longitudinal rectifying plate 52, which are cross-connected to form rectifying holes 53, and the transverse rectifying plate 51 is parallel to the end surface of the arc plate in the circumferential direction. As a result, the transverse rectifying plate 51 and the longitudinal rectifying plate 52 have the smallest cross-sectional area in the outlet direction of the airflow of the air outlet 300, so as to avoid the transverse rectifying plate 51 and the longitudinal rectifying plate 52 from obstructing the airflow.

[0075] More specifically, the longitudinal rectifying plate 52 may extend along the circumference of the arc-shaped plate, whereby the rectifying grid 5 may form a circumferentially extending portion of the arc-shaped plate, thereby making the arc surface of the air guide portion larger and having a better visual appearance.

[0076] Specifically, the outer air guide plate 16 is adapted to be closely matched with the opening edge of the air outlet 300 when the air guide portion guides the air flow blown out from the air outlet 300 of the air conditioning system. For example, when the air guide portion guides the air flow blown out from the air outlet 300 of the air conditioning system, the gap distance between the outer air guide plate 16 and the opening edge of the air outlet 300 can be less than 5 mm, so that the outer air guide plate 16 and the opening edge of the air outlet 300 are relatively sealed, so as to prevent dust from entering the air conditioning system through the gap between the outer air guide plate 16 and the opening edge of the air outlet 300.

[0077] Optionally, the air guiding portion has a shielding position for shielding the air outlet 300 , a hot air guiding position for guiding the airflow downward, and a cold air guiding position for guiding the airflow upward.

[0078] Since the specific gravity of hot air is lower than that of cold air, Figure 2 As shown, when the air conditioning system is cooling, the air guide portion guides the cold air flow blown out from the air outlet 300 to blow upward or obliquely upward into the room (such as Figure 2 As shown by the arrow, the air guide portion is located at the cold air guiding position. After the cold air flow is blown into the room, it flows downward under the action of gravity, thereby making the cold air evenly distributed in the room and achieving a better indoor cooling effect.

[0079] like Figure 3 As shown, when the air conditioning system is heating, the air guide portion guides the hot air flow blown out from the air outlet 300 to blow downward or obliquely downward into the room (such as Figure 3 As shown by the arrow, the air guide part is located at the hot air guiding position. After the hot air flow is blown into the room, it flows upward due to its lighter gravity, thereby making the hot air evenly distributed in the room and achieving a better indoor heating effect.

[0080] In addition, if Figure 4 As shown, when the air-conditioning system stops working, no airflow blows out of the air outlet 300, and the air guide part can be rotated to a blocking position to block the air outlet 300. Thus, the air guide part can prevent external dust from entering the air-conditioning system through the air outlet 300 when the air-conditioning system stops working.

[0081] In some specific embodiments, when the air guide is located at the hot air guiding position or the cold air guiding position, the airflow guiding surface 13 of the air guide is smoothly connected with the internal air duct line of the air conditioning system. In other words, when the air guide is located at the hot air guiding position, the airflow guiding surface 13 of the air guide is smoothly connected with the internal air duct line of the air conditioning system at the air outlet 300, and the hot air blown out of the air outlet 300 can be blown out smoothly from the air guide. When the air guide is located at the cold air guiding position, the airflow guiding surface 13 of the air guide is smoothly connected with the internal air duct line of the air conditioning system at the air outlet 300, and the cold air blown out of the air outlet 300 can be blown out smoothly from the air guide.

[0082] The air guide portion is suitable for rotating from the shielding position to the hot air guiding position by an angle α, and the air guide portion is suitable for rotating from the shielding position to the cold air guiding position by an angle β. α is 30°-80°, so that the angle of the air guide portion is reasonable, and the hot air flow blown out of the air outlet 300 can be discharged smoothly, with a large air volume and low noise when the air conditioner is heating. β is 40°-110°, so that the angle of the air guide portion is reasonable, so that the cold air flow blown out of the air outlet 300 can be discharged smoothly, with a large air volume and low noise when the air conditioner is cooling.

[0083] More specifically, α is 55° and β is 80°. Thus, the angle of the air guide is further reasonable, and the airflow blown out of the air outlet 300 can be further discharged smoothly, with a large air volume and low noise.
