Detailed Description
Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the invention.
A deflector 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings, and the deflector 100 may be used in an air conditioning apparatus.
As shown in fig. 1, a flow guiding device 100 for an air conditioning apparatus according to an embodiment of the present invention includes: a support frame 1, a plurality of wind guiding blades 2 and a driving device 3.
Wherein, as shown in fig. 2, the support frame 1 may include an inner support part 11 and an outer support part 12, the inner support part 11 may be disposed radially inside the outer support part 12, the inner support part 11 may be spaced apart from the outer support part 12 to define a circulation space 1a for air flow, and the air flow in the air conditioner may circulate in the circulation space 1a. For example, the inner support member 11 and the outer support member 12 may each be formed in a cylindrical shape, the outer support member 12 being located outside the inner support member 11 and extending around the inner support member 11, the outer support member 12 being spaced apart from the inner support member 11 to define the flow-through space 1a. When the air conditioning apparatus is in operation, an air flow in the air conditioning apparatus can circulate into the circulation space 1a. It is of course understood that the structural design of the inner support member 11 and the outer support member 12 is not limited thereto, as long as the flow-through space 1a can be defined.
As shown in fig. 1-2, a plurality of wind guiding blades 2 may be disposed in the circulation space 1a and the plurality of wind guiding blades 2 may be spaced apart in the circumferential direction of the support frame 1, and both axial ends of each wind guiding blade 2 may be pivotally connected to the inner support member 11 and the outer support member 12, respectively, whereby the plurality of wind guiding blades 2 may be pivoted with respect to the inner support member 11 and the outer support member 12 to adjust the circulation direction of the air flow.
As shown in fig. 2, the driving device 3 may be disposed outside the outer support member 12, and the driving device 3 may be connected to at least one wind guiding blade 2 and drive the wind guiding blade 2 to rotate so as to adjust the flowing direction of the air flow in the flowing space 1 a. That is, the driving device 3 may drive one of the wind guiding blades 2 to rotate relative to the supporting frame 1, the driving device 3 may also drive a part of the wind guiding blades 2 to rotate relative to the supporting frame 1, and the driving device 3 may also drive all of the wind guiding blades 2 to rotate relative to the supporting frame 1. The number of driving devices 3 may be one or plural. When the driving device 3 is one, the driving device 3 can drive the plurality of wind guiding blades 2 to rotate at the same time. When the number of the driving devices 3 is plural, the plural driving devices 3 can respectively drive the wind guiding blades 2 corresponding to the driving devices to rotate.
It can be appreciated that, since the driving device 3 may be located radially outside the outer support member 12, the driving device 3 may avoid the circulation space 1a of the air flow, so that the circulation resistance of the air flow may be reduced, and the air outlet efficiency of the air guiding device 100 may be improved.
Specifically, when the air guiding device 100 works, the driving device 3 can drive the air guiding blades 2 to rotate relative to the supporting frame 1, so that the air outlet direction of the air outlet space between two adjacent air guiding blades 2 can be adjusted. It can be appreciated that, because the plurality of wind guiding blades 2 are distributed in the circumferential direction of the supporting frame 1, when the driving device 3 drives the plurality of wind guiding blades 2 to rotate by a certain angle, the air flow flowing out from between the plurality of wind guiding blades 2 can form a rotating air flow, and the rotating air flow can be dispersed around the rotation axis of the rotating air flow when flowing, so that the wind dispersing effect can be achieved, the air supply range can be enlarged, the air supply effect of natural wind can be simulated, the air flow can be softer, and the air supply uniformity of the flow guiding device 100 can be improved.
For example, the flow guiding device 100 may be applied to an air conditioning indoor unit, and a heat exchange airflow in the air conditioning indoor unit may circulate into an indoor space through the flow guiding device 100. When the indoor unit of the air conditioner works, the driving device 3 can drive the air guide blades 2 to rotate to a certain angle relative to the supporting frame 1, so that heat exchange air flowing out from among the plurality of air guide blades 2 can form rotary air flow, the rotary air flow can flow in the indoor space in a rotary mode and spread all around, the air supply effect of natural air can be simulated, discomfort caused by direct blowing of the heat exchange air flow to a user can be prevented, and accordingly air supply uniformity and use comfort of the indoor unit of the air conditioner can be improved.
In addition, when the indoor unit of the air conditioner works, the rotation angle of the air guide blade 2 can be controlled to adjust the air output of the air guide device 100. For example, when a user just starts to open the indoor unit of the air conditioner, the driving device 3 can be controlled to rotate the air guide blades 2 by a larger inclination angle relative to the support frame 1, so that the air outlet space between two adjacent air guide blades 2 can be increased, the air outlet quantity of the air guide device 100 can be increased, and the refrigerating and heating efficiency of the indoor unit of the air conditioner can be improved. When the indoor temperature of the air conditioner basically reaches the ideal temperature of a user after the indoor machine works for a period of time, the driving device 3 can be controlled to enable the air guide blades 2 to rotate by a small inclination angle relative to the supporting frame 1, so that the air outlet space between two adjacent air guide blades 2 can be reduced, the air outlet quantity of the air guide device 100 can be reduced, and the indoor temperature can stably maintain the current ideal temperature. Therefore, through the arrangement, the air supply mode of the indoor unit of the air conditioner can be changed by controlling the rotation angle of the air guide blade 2, and the use flexibility of a user is greatly improved.
According to the air guiding device 100 for an air conditioning apparatus of the embodiment of the present invention, the driving device 3 may drive the plurality of air guiding blades 2 to rotate by the plurality of air guiding blades 2 arranged in the circumferential direction of the circulation space 1a at intervals, so that the air flow flowing out of the air guiding device 100 may form a rotating air flow, thereby increasing the air supply range of the air guiding device 100, simulating the air supply effect of natural air, and making the air flow softer, so as to improve the air supply uniformity of the air guiding device 100.
As shown in fig. 1-3, according to some embodiments of the present invention, the driving device 3 may include a driving member 31, a driving gear 32, a gear ring 33, and a transmission member 34, where the driving member 31 may be disposed on the support frame 1, the driving gear 32 may be connected to the driving member 31 to be driven to rotate by the driving member 31, the gear ring 33 may be sleeved on the outer support member 12, the gear ring 33 may be engaged with the driving gear 32, the driving gear 32 may drive the gear ring 33 to rotate around the outer support member 12, one end of the transmission member 34 may be movably connected to the gear ring 33, the other end of the transmission member 34 may be connected to an end, close to the outer support member 12, of the wind guiding blade 2, and when the gear ring 33 rotates, the transmission member 34 may be driven to rotate relative to the outer support member 12. Therefore, through the arrangement, the structural design of the driving device 3 is simpler, the operation is stable and the operation is convenient, the driving piece 31 can also realize a driving mode of 'one driving more than one driving', namely one driving piece 31 can simultaneously drive a plurality of wind guide blades 2 to rotate, and the driving efficiency of the driving device 3 is greatly improved.
Alternatively, the plurality of driving gears 32 may be plural, the plurality of driving gears 32 may be different in modulus and the plurality of driving gears 32 may be sequentially engaged. Therefore, the plurality of driving gears 32 are matched with each other to perform variable-speed rotation on the driving piece 31, so that the rotation speed of the wind guide blade 2 can be flexibly adjusted.
For example, in the specific example shown in fig. 2, the ring gear 33 and the outer support member 12 are each formed in a cylindrical shape, and the ring gear 33 is sleeved on the outer support member 12. The plurality of transmission members 34 are arranged at intervals in the circumferential direction of the gear ring 33, and the plurality of transmission members 34 are arranged in one-to-one correspondence with the plurality of wind guide vanes 2. Wherein, the axial one end of each driving member 34 is movably connected with the gear ring 33, and the axial other end of each driving member 34 is connected with the corresponding wind guiding blade 2. When the driving device 3 is operated, the driving member 31 may transmit power to the driving gear 32, the driving gear 32 rotates and drives the ring gear 33 to rotate, and the ring gear 33 may rotate around the outer support member 12. Because one end of the transmission piece 34 is movably connected with the gear ring 33, when the gear ring 33 rotates, one end of the transmission piece 34 matched with the gear ring 33 can rotate along with the gear ring 33, and under the action of the rotation moment, one end of the transmission piece 34 matched with the wind guiding blade 2 can drive the wind guiding blade 2 to rotate, so that the purpose of adjusting the rotation angle of the wind guiding blade 2 can be achieved. Thus, by the above arrangement, the rotation angles of the plurality of wind guiding blades 2 can be simultaneously controlled by the driving member 31, and the operation is convenient.
Optionally, when the air conditioning device works, the driving device 3 may be controlled to drive the plurality of air guiding blades 2 to rotate to a set angle, and the air flow may circulate along the current angle. Alternatively, when the air conditioning apparatus is operated, the driving member 31 may be controlled to rotate clockwise for a set time, and then the driving member 31 may be controlled to rotate counterclockwise again for a set time, thereby reciprocating. Therefore, the driving device 3 can drive the plurality of air guiding blades 2 to reciprocate, so that the air flow flowing out of the air guiding device 100 is more similar to natural wind, and the air supply uniformity of the air guiding device 100 can be greatly improved.
As shown in fig. 2, in some embodiments of the present invention, the gear ring 33 may include a tooth-shaped portion 331 and a transmission portion 332, the tooth-shaped portion 331 may be sleeved on the outer support member 12, a plurality of engagement teeth engaged with the driving gear 32 may be provided on an outer peripheral wall of the tooth-shaped portion 331, the transmission portion 332 may be connected to the tooth-shaped portion 331 and extend in a direction away from the tooth-shaped portion 331 in an axial direction of the support frame 1, and one end of the transmission member 34 may be movably connected to the transmission portion 332. Therefore, through the arrangement, the structural design of the gear ring 33 can be more reasonable, and the transmission part 332 can define sufficient assembly space, so that the assembly of the transmission piece 34 and the gear ring 33 can be facilitated.
Alternatively, both the tooth 331 and the transmission 332 may be formed in a cylindrical shape, and the inner diameters of the tooth 331 and the transmission 332 may be the same. A plurality of teeth may be provided on a cylindrical base body to form the tooth-shaped portion 331, and a portion of the base body where no teeth are provided may be formed as the transmission portion 332, whereby, by the above arrangement, the tooth-shaped portion 331 and the transmission portion 332 may be formed as an integral piece, and the manufacturing manner of the ring gear 33 may be made simpler. It will of course be appreciated that the toothed portion 331 and the transmission portion 332 may also be formed as separate pieces, and that the toothed portion 331 and the transmission portion 332 may be connected together to form the ring gear 33.
As shown in fig. 3, in some embodiments of the present invention, the transmission part 332 may be provided with a mating post 333 protruding outwards (radially outwards) with respect to the transmission part 332, the transmission member 34 may be provided with a sliding groove 341 extending in an axial direction of the transmission member, and at least a portion of the mating post 333 may extend into the sliding groove 341 and slidingly engage with the sliding groove 341, thereby making the engagement between the transmission member 34 and the transmission part 332 simpler and the operation of the driving device 3 smoother. Specifically, the sliding groove 341 may define a moving space of the mating post 333. When the gear ring 33 rotates relative to the outer support member 12, the engaging post 333 slides in the sliding groove 341, and the end of the transmission member 34 engaged with the gear ring 33 rotates relative to the end of the transmission member 34 engaged with the wind guiding vane 2, so that the wind guiding vane 2 can be driven to rotate. When the engaging post 333 moves to one end of the sliding groove 341 away from the wind guiding blade 2, the wind guiding blade 2 stops rotating. Therefore, the sliding groove 341 can also play a limiting role, and the rotation angle range of the wind guiding blade 2 can be controlled by controlling the extension length of the sliding groove 341.
Alternatively, the engaging post 333 may be formed as an integral piece with the transmission portion 332, so that the structure of the ring gear 33 may be simpler and the assembly efficiency of the deflector 100 may be improved. Alternatively, as shown in fig. 2 to 3, a fitting hole 332a may be provided on the transmission portion 332, and a portion of the fitting post 333 may protrude into the fitting hole 332 a. Wherein, the mating post 333 may be interference fit with the mounting hole 332a, and the mating post 333 may be screw-fit with the mounting hole 332 a. It is of course understood that the manner of engagement between the engagement post 333 and the transmission portion 332 is not limited thereto. For example, the mating posts 333 may also be secured to the transmission 332 using a welded connection.
As shown in fig. 3, in some embodiments of the present invention, the flow guiding device 100 may further include a roller 35, the roller 35 may be sleeved on the mating post 333 and the roller 35 may be in rolling engagement with the sliding groove 341, thereby further improving the operation smoothness of the driving device 3.

Wherein, can be equipped with the air outlet on the casing, braced frame 1 can be fixed on the casing and circulation space 1a can communicate with the air outlet.
For example, the air conditioning equipment may be an air conditioning indoor unit, an air inlet and an air outlet are arranged on a casing of the air conditioning indoor unit, and a heat exchanger is arranged in the casing. The supporting frame 1 of the flow guiding device 100 is fixed on the casing, and the ventilation space 1a defined by the supporting frame 1 is communicated with the air outlet duct of the air indoor unit.
When the indoor unit of the air conditioner works, indoor air can enter the shell through the air inlet, air flow exchanges heat with the heat exchanger in the shell to form heat exchange air flow, the heat exchange air flow can circulate in the air outlet air duct, and the heat exchange air flow can circulate from the air outlet air duct to the circulation space 1a in the flow guiding device 100. At this time, the driving member 31 may be controlled to rotate, the driving member 31 may transmit power to the driving gear 32, the driving gear 32 may rotate and drive the ring gear 33 to rotate, and the ring gear 33 may rotate around the outer support member 12. Because one end of the transmission piece 34 is movably connected with the gear ring 33, when the gear ring 33 rotates, one end of the transmission piece 34 matched with the gear ring 33 can rotate along with the gear ring 33, and under the action of the rotation moment, one end of the transmission piece 34 matched with the wind guiding blade 2 can drive the wind guiding blade 2 to rotate, so that the purpose of adjusting the rotation angle of the wind guiding blade 2 can be achieved.
When the plurality of wind guiding blades 2 rotate to a set angle, the wind guiding blades 2 stop rotating. Since the plurality of wind guide blades 2 are distributed in the circumferential direction of the support frame 1, the heat exchange air flow flowing out from between the plurality of wind guide blades 2 can form a rotating air flow, and the rotating air flow can enter the indoor space through the air outlet. The rotary airflow can be dispersed around the rotation axis of the rotary airflow when flowing, so that the air supply range of the air conditioner indoor unit can be enlarged, and the refrigerating and heating efficiency of the air conditioner indoor unit can be improved. In addition, the rotating air flow can simulate the air supply effect of natural air, so that the heat exchange air flow becomes softer, discomfort caused by direct blowing of the heat exchange air flow to a user can be prevented, and the air supply uniformity and the use comfort of the air conditioner indoor unit can be improved.
