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

First, an air guiding device 100 according to an embodiment of the present invention is described with reference to fig. 1 to 11.

As shown in fig. 1 to fig. 11, the air guiding device 100 according to the embodiment of the invention may include an air guiding portion (for example, a first air guiding portion 11, which is only exemplarily illustrated), the air conditioning system has an air outlet 300, and hot air or cold air blown out from the air conditioning system may be blown into a room through the air outlet 300. The air guide portion guides an air flow blown out from the outlet 300 of the air conditioning system, and an air flow guide surface 13 for guiding the air flow blown out from the outlet 300 into the room is formed on one side of the air guide portion.

As shown in fig. 6, 8 and 9, the air guide portion is provided with a flow straightening grill 5 on at least one side in the airflow direction. The rectification grille 5 can rectify the air flow flowing through the air guide part, so that the air flow is more uniformly blown to the indoor space from the air outlet 300, and the heat exchange effect of the air conditioning system is improved. In addition, the rectifying grating 5 can rotate along with the air guide part, so that when the air guide part rotates to different angles to guide the air flow to different directions, the rectifying grating 5 can rectify the air flow blown out from the directions, the rectifying effect is better, meanwhile, the rectifying grating 5 has smaller obstruction to the air flow all the time, the air conditioning system has larger air output, and the temperature adjusting effect of the air conditioning system is ensured.

Specifically, as shown in fig. 1-4, the outlet 300 is located near the bottom panel 200 of the air conditioning system.

Specifically, as shown in fig. 2 to 4, the air guiding portion includes a plurality of air guiding portions (for example, a first air guiding portion 11 and a second air guiding portion 12, which are only exemplarily described), each of the air guiding portions is respectively located at a different position of the air outlet 300, and the air guiding portions are rotatable to change a guiding angle of the air guiding portions to the air flow. The different air guide parts are rotated to different angles respectively, so that air flows blown out from different positions of the air outlet 300 corresponding to the air guide parts can be guided to different directions, and more air blowing requirements of the air conditioning system are met.

In some alternative embodiments of the present invention, the plurality of wind-guiding portions are sequentially arranged along the length direction of the wind outlet 300 (i.e. along the rotation axis direction of the wind-guiding portion). Therefore, the air guide parts can guide the air flows blown out from different positions of the length direction of the air outlet 300 to different directions, the air blowing angle is free, and the requirement that the air conditioning system blows the air flows in multiple directions simultaneously can be met.

In some specific embodiments, two air guiding portions are provided, the two air guiding portions are disposed along the length direction of the air outlet 300, two ends of the length direction of the air outlet 300 are respectively provided with one air guiding portion driving device 2, and each air guiding portion driving device 2 is respectively used for driving one air guiding portion adjacent to the air guiding portion driving device 2 to rotate. Specifically, the air guiding portion driving device 2 is a motor, and an output shaft of the motor of the air guiding portion driving device 2 can be connected with the air guiding portion to drive the air guiding portion to rotate.

In other specific embodiments, the number of the air guiding portions is three or more, and along the length direction of the air outlet 300, an installation portion is arranged between two adjacent air guiding portions, the installation portion is fixed on the air conditioning system (for example, fixed with the bottom plate 200 of the air conditioning system), each installation portion is provided with an air guiding portion driving device 2, and each air guiding portion driving device 2 is used for driving at least one air guiding portion to rotate. For example, each wind guide portion driving device 2 may drive the wind guide portion on one side or both sides adjacent to the wind guide portion to rotate.

In other specific embodiments, as shown in fig. 10 and 11, a plurality of wind-guiding portions may be sequentially arranged along the width direction of the wind outlet 300 (i.e. along the circumferential direction of the rotation axis of the wind-guiding portion). Therefore, the opening angle between the two adjacent air guide parts can be changed by rotating the different air guide parts, and the airflow is blown into the room through the space between the two adjacent air guide parts. Compared with the prior art in which only one air guide part is arranged, the arrangement mode can enable the airflow of the air outlet 300 to have more blowing angles and larger blowing area, and further meet different requirements of blowing the airflow by people. In addition, when only one air guiding part is used for blowing air, other air guiding parts can seal the air outlet 300, and dust entering from the air outlet 300 is avoided.

As shown in fig. 9, at least one end of the outlet 300 in the longitudinal direction is provided with an air guide portion driving device 2 for driving the air guide portion to rotate. The air guide part driving device 2 can be a motor, and an output shaft of the motor can be connected with the air guide part to drive the air guide part to rotate.

Specifically, as shown in fig. 1 and 8, the end caps 3 are respectively sleeved at two ends of the air guiding device 100 in the length direction of the air outlet 300, the end caps 3 may be cylindrical caps with one axial end open, and the end caps 3 may seal the air guiding portion at two axial ends to prevent external dust from entering the air outlet 300 from the two axial ends of the air guiding portion.

An installation space 31 is provided in the end cap 3, and an air guide part driving device 2 for driving the air guide part to rotate is provided in the installation space 31, so that the end cap 3 protects the air guide part driving device 2 for driving the air guide part to rotate.

In some specific embodiments, as shown in fig. 11, the end cap 3 is fixed to at least one air guiding portion, so that the end cap 3 can rotate together with the air guiding portion, the end cap 3 is provided with an avoiding notch 32 for avoiding the driving device 2 of the air guiding portion when rotating along with the air guiding portion, the avoiding notch 32 may not be provided with an opening on a side wall of the end cap 3, the driving device 2 of the air guiding portion is fixed in the air conditioning system (for example, the driving device 2 of the air guiding portion is fixed to a bottom plate 200 of the air conditioning system) and does not rotate along with the end cap 3, when the end cap 3 rotates along with the air guiding portion, the end cap 3 rotates relative to the driving device 2 of the air guiding portion.

In other embodiments, as shown in fig. 1 and 10, the end cap 3 is secured within an air conditioning system. At this time, both the end cap 3 and the air guiding portion driving device 2 are fixed in the air conditioning system (for example, both the end cap 3 and the air guiding portion driving device 2 are fixed to the bottom plate 200 of the air conditioning system), and at this time, the air guiding portion rotates relative to the end cap 3.

In some embodiments, as shown in fig. 7 to 9, at least one of the wind guiding portions is installed with a louver structure 41, so that the louver structure 41 can rotate along with the wind guiding portion, and the louver structure 41 does not need to be disposed in the wind outlet 300, thereby reducing the space occupied by the louver structure 41 inside the air conditioning system. The louver structure 41 has a plurality of wind-sweeping blades 411, the plurality of wind-sweeping blades 411 are arranged at intervals along the rotation axis of the wind guide portion, and the plurality of wind-sweeping blades 411 can swing along the rotation axis direction of the wind guide portion. Therefore, when the airflow blown out from the air outlet 300 passes through the air guiding portion, the airflow direction can be further changed by the plurality of wind sweeping blades 411, so as to meet different blowing requirements of users.

As shown in fig. 7 and 9, the air guiding device 100 further includes: a louver driving structure 43 and a louver transmission structure 42, the louver driving structure 43 is suitable for enabling the plurality of wind sweeping blades 411 of the louver wind sweeping structure 41 to swing along the rotation axis of the wind guiding part through the louver transmission structure 42. In some embodiments, the wind sweeping blades 411 are perpendicular to the wind guiding portion, when the wind guiding portion driving device 2 drives the wind guiding portion to rotate, the wind sweeping blades 411 rotate along with the wind guiding portion, and the louver driving structure 43 drives the wind sweeping blades 411 to swing along the rotation axis direction of the wind guiding portion, so that the wind guiding device 100 can continuously guide the airflow blown out from the wind outlet 300 to multiple directions, thereby enabling the airflow to be blown uniformly in the room and improving the heat exchange effect of the air conditioning system.

In some specific embodiments, as shown in fig. 7 and 9, the bottom of the plurality of wind sweeping blades 411 (i.e. the side of the wind sweeping blades 411 facing the wind guiding portion) is provided with a through hole 412, and the louver transmission structure 42 includes: the louver driving mechanism comprises a pull rod 421 and a transition transmission rod 422, wherein the pull rod 421 is suitable for being provided with a plurality of through holes 412 in a penetrating mode, the end portion of the pull rod 421 is provided with a limiting hole 424, one end of the transition transmission rod 422 is suitable for being sleeved on an output shaft of the louver driving structure 43, the transition transmission rod 422 is suitable for being provided with the limiting hole 424 in a penetrating mode, and the limiting hole 424 can be a long round hole. The output shaft of the louver driving structure 43 can drive the transition transmission rod 422 to rotate, so that the transition transmission rod 422 moves in the limiting 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 wind guiding portion). It is understood that the tie bar 421 can be moved in both directions in the arrangement direction of the wind sweeping blades 411.

As shown in fig. 7, a plurality of pushing protrusions 423 are arranged at intervals in the length direction of the pull rod 421, the pushing protrusions 423 correspond to one wind sweeping blade 411 respectively, for example, one pushing protrusion 423 is arranged between every two wind sweeping blades 411, and the volume or height of each pushing protrusion 423 is larger than that of each through hole 412, so as to prevent the pushing protrusion 423 from passing through each 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 pushing protrusion 423 is clamped at the through hole 412 of one wind sweeping blade 411 and pushes the wind sweeping blade 411 to swing along the movement direction of the pull rod 421. The louver driving structure 43 can swing the wind sweeping blades 411 to different angles through the position change of the driving pull rod 421. In particular, the louver driving structure 43 may be a motor.

In some embodiments, the louver driving structure 43 and the air guide driving device 2 may be fixed in the air conditioning system (e.g., fixed to the bottom plate 200), and the louver driving structure 43 and the air guide driving device 2 may be installed in the installation cavity 17. The louver driving structure 43 can thereby escape from the air flow guide surface 13, facilitating the air flow to be blown into the room through the air flow guide surface 13.

Specifically, the integrated motor 6 is arranged in the installation cavity 17 of the end cover 3, the integrated motor 6 is provided with an air guiding part output shaft and a shutter output shaft, the air guiding part output shaft forms the air guiding part driving device 2, and the shutter output shaft forms the shutter driving structure 43, so that the integrated motor 6 can output power to the rotation of the air guiding part and the swinging of the wind sweeping blades 411 at the same time, and the integrated motor is stronger in integration and more convenient to arrange.

More specifically, the free end of the portion 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, and the bending limiting section can prevent the transition transmission rod 422 from coming out of the limiting hole 424 when the pull rod 421 moves along the arrangement direction of the plurality of wind sweeping blades 411.

Alternatively, as shown in fig. 5, 6 and 9, each air guiding portion includes an arc-shaped plate, an air flow guiding surface 13 is formed on the surface of the arc-shaped plate, and the axis of a cylinder where the arc-shaped plate is located is the rotation axis of the air guiding portion, so that the rotation process of the air guiding portion can be more stable, and the air guiding angle of the air guiding portion can be effectively increased. At least one axial end of the arc-shaped plate is provided with a connecting plate 14 which is suitable for being matched with the air guiding part driving device 2 in a rotating mode, and therefore the air guiding part driving device 2 can drive the air guiding part to rotate.

As shown in fig. 5, the air guide portion includes: the air-conditioner comprises an inner air deflector 15 and an outer air deflector 16, wherein the inner air deflector 15 is connected with the outer air deflector 16, an installation cavity 17 is formed between the inner air deflector 15 and the outer air deflector 16, a heat insulation material is arranged in the installation cavity 17, and the heat insulation material can be sponge, so that the heat insulation performance of the air guiding part is strong, and the air flow is prevented from generating condensed water when passing through the air guiding part and causing the condensed water to flow back to the air outlet 300. The surface of the inner air deflector 15 on the side facing away from the mounting cavity 17 forms an air flow guide surface 13.

Specifically, as shown in fig. 5, the surface of the inner air guiding plate 15 facing the installation cavity 17 or/and the surface of the outer air guiding plate 16 facing the installation cavity 17 are provided with a limiting protrusion 18 for positioning the thermal insulation material, and the limiting protrusion 18 can fix the thermal insulation material in the installation cavity 17 firmly.

As shown in fig. 7, the air flow guide surface 13 of the louver air-sweeping structure 41 mounted on the air flow guide surface 13 is provided with a mounting hole 131 communicated with the mounting cavity 17, a portion of the louver driving structure 43 is adapted to protrude from the mounting hole 131 into the mounting cavity 17, and a portion of the louver driving structure 43 protruding out of the air flow guide surface 13 is mounted with the louver air-sweeping structure 41 through the louver transmission structure 42. Thus, the space for disposing the louver driving structure 43 can be saved, and the louver driving structure 43 can be prevented from being too bulky at the air flow guide surface 13 to obstruct the air flow.

In some specific embodiments, the inner wind deflector 15, the outer wind deflector 16 and the wind sweeping blade 411 are integrally formed. Therefore, the air guide part is high in overall strength and convenient to mount. More specifically, the wind sweeping blade 411 is made of a flexible component (for example, a plastic component, the inner wind deflector 15, the outer wind deflector 16 and the wind sweeping blade 411 are integrally injection-molded), so that the wind sweeping blade 411 is convenient to deform relative to the inner wind deflector 15 and swing of the wind sweeping blade 411.

In other specific embodiments, the inner wind deflector 15, the outer wind deflector 16 and the wind sweeping blade 411 may be separately manufactured and then fixed by bonding or the like. Therefore, the air guide part can be conveniently manufactured.

More specifically, as shown in fig. 6, the two sides of the air guiding portion along the airflow flowing direction are respectively provided with the rectifying grids 5, and the rectifying holes 53 of the rectifying grids 5 on the two sides of the airflow flowing direction are directly opposite to each other. Therefore, the airflow can be blown through the opposite rectification holes 53 in sequence, so that the rectification holes 53 on the two sides can better rectify the airflow blown out of the air outlet 300, and the heat exchange effect of the air conditioning system is improved.

More specifically, as shown in fig. 6, the flow rectification grid 5 has a lateral flow rectification plate 51 and a longitudinal flow rectification plate 52, the lateral flow rectification plate 51 and the longitudinal flow rectification plate 52 are cross-connected to form a flow rectification hole 53, and the lateral flow rectification plate 51 is parallel to the end face in the circumferential direction of the arc-shaped plate. Therefore, the cross sectional area of the transverse rectifying plate 51 and the longitudinal rectifying plate 52 in the air outlet direction of the airflow of the air outlet 300 is the minimum, the transverse rectifying plate 51 and the longitudinal rectifying plate 52 are prevented from blocking the airflow, and the air conditioning system is ensured to have larger air outlet volume.

More specifically, the longitudinal rectifying plate 52 may extend along the circumferential direction of the arc-shaped plate, and thus the rectifying grating 5 may form a circumferentially extending portion of the arc-shaped plate, so that the arc surface of the air guiding portion is larger, and the appearance is better.

Specifically, the outer air guiding plate 16 is adapted to fit closely to the opening edge of the outlet 300 when the air guiding portion guides the airflow blown out from the outlet 300 of the air conditioning system. For example, when the air guiding portion guides the airflow blown out from the air outlet 300 of the air conditioning system, the gap distance between the outer air guiding plate 16 and the opening edge of the air outlet 300 may be less than 5mm, so as to achieve the relative sealing between the outer air guiding plate 16 and the opening edge of the air outlet 300, so as to prevent dust from entering the air conditioning system from the gap between the outer air guiding plate 16 and the opening edge of the air outlet 300.

Alternatively, the air guide portion has a shielding position for shielding the air outlet 300, a hot air guide position for guiding the air flow downward, and a cold air guide position for guiding the air flow upward.

Since the specific gravity of the hot air is lower than that of the cold air, as shown in fig. 2, when the air conditioning system is refrigerating, the air guiding portion guides the cold air flow blown out from the air outlet 300 to blow upwards or obliquely upwards to the indoor (as shown by an arrow in fig. 2), and at this time, the air guiding portion is located at the cold air guiding position, and the cold air flow blows towards the indoor and then flows downwards under the action of gravity, so that the cold air can be uniformly distributed in the indoor, and the indoor refrigerating effect is better.

As shown in fig. 3, when the air conditioning system heats, the air guiding portion guides the hot air flow blown out from the air outlet 300 to blow downward or obliquely downward into the room (as shown by the arrow in fig. 3), and at this time, the air guiding portion is located at the hot air guiding position, and the hot air flow flows upward due to the light gravity after blowing into the room, so that the hot air can be uniformly distributed in the room, and the indoor heating effect is better.

In addition, as shown in fig. 4, when the air conditioning system stops working, no air flow is blown out from the air outlet 300, and the air guiding portion can rotate to the shielding position to shield the air outlet 300, so that the air guiding portion can prevent external dust from entering the air conditioning system through the air outlet 300 when the air conditioning system stops working.

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

The air guiding part is suitable for rotating an angle alpha from the shielding position to the hot air guiding position, and the air guiding part is suitable for rotating an angle beta from the shielding position to the cold air guiding position.
