Detailed Description

The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.

As shown in fig. 1-9, an air outlet device comprises: the cross-flow wind wheel comprises a cross-flow wind wheel 100, a wind wheel driving device 130, a wind guide structure and an air outlet array mechanism 140; the air outlet array mechanism 140 includes: a plurality of layers of air duct layer structures which are stacked up and down; the cross-flow wind wheel 100 is vertically arranged and is in transmission connection with the wind wheel driving device 130; the air guide structure is arranged on the outer side of the cross-flow wind wheel 100 and is used for guiding air on the outer side of the cross-flow wind wheel 100; an air inlet and an air outlet are respectively arranged on two sides of the air guide structure; the air outlet array mechanism 140 is covered on the outer side of the air guide structure; the air duct layer structure can horizontally rotate around the air guide structure; the top surface of the air duct layer structure is provided with a limiting column 311, and the bottom surface of the air duct layer structure is provided with a limiting part clamped with the limiting column 311; when the air duct layers are vertically overlapped, the adjacent air ducts are connected through the limit column 311 and the limit part in a clamping mode. The cross-flow wind wheel 100 can be a cross-flow wind wheel 100, and the wind wheel driving device 130 and the unit driving device 400 are motors. The air outlet equipment only needs to be provided with the air outlet array mechanism 140 which is used for driving the group and guiding the air components and is more flexible in direction adjustment, and the purpose of comprehensively exhausting air around the air outlet equipment can be achieved.

As shown in fig. 4 and 5, the air guide structure includes: a volute guide plate 210 and an auxiliary guide plate 220; the volute guide plate 210 is strip-shaped and provided with an air guide arc surface 211; the air guide cambered surface 211 is arranged close to a part of cylindrical surface of the cross-flow wind wheel 100; the two sides of the air guide cambered surface 211 are an air inlet side and an air outlet side respectively, and the distance between the air guide cambered surface 211 and the cylindrical surface of the cross flow wind wheel 100 is gradually increased from the air inlet side to the air outlet side; the auxiliary guide plate 220 is plate-shaped, one side of the auxiliary guide plate is close to the cross-flow wind wheel 100, the other side of the auxiliary guide plate deviates from the cylindrical surface of the cross-flow wind wheel 100 and extends outwards, and the areas where the air outlet sides of the auxiliary guide plate 220 and the volute guide plate 210 are located are arranged oppositely and are respectively located on the same side of the cross-flow wind wheel 100.

When the cross-flow wind wheel 100 rotates around the rotation axis of the cross-flow wind wheel to a specific direction, the air is driven to enter the inner side of the volute guide plate 210, the air can continuously flow along the air guide arc surface 211 and finally flows out from the outlet on the other side of the cross-flow wind wheel 100, and the distance between the air guide arc surface 211 and the cross-flow wind wheel 100 can reduce noise and further improve air outlet quantity and air outlet speed; therefore, when the cross-flow wind wheel 100 rotates, air can be driven to enter from one side of the cross-flow wind wheel 100 along a specific direction and then flow out from the other side. Compared with the existing air outlet equipment, the air guide structure arranged on the air outlet equipment is simplified, the production and installation cost and difficulty can be greatly reduced, and the air guide structure is not required to be wrapped by an equipment shell completely, so that the equipment shell can be removed by the special design of the air guide structure, the air outlet array mechanism 140 can be enabled to have a larger selection range of the inlet and outlet directions in the horizontal direction while the stable air inlet and outlet path of the air outlet equipment is ensured, and the air outlet equipment can realize the air blowing effect on users in a larger range.

An air guide area 212 is arranged on the air outlet side of the volute guide plate 210, the auxiliary guide plate 220 and the air guide area 212 are opposite to form an air outlet channel, and the width of the air outlet channel on the same horizontal plane is increased along the direction departing from the cross flow wind wheel 100; an arc plate 221 extends from the cylindrical surface of the cross-flow wind wheel 100 along one side edge of the auxiliary guide plate 220 close to the cross-flow wind wheel 100, the arc plate 221 is arranged close to the cylindrical surface of the cross-flow wind wheel 100, and an air guide gap 222 is arranged between the inner side surface of the arc plate 221 and the cylindrical surface of the cross-flow wind wheel 100.

The wind guide areas 212 are arranged on the two sides of the wind outlet channel, so that airflow entering the wind outlet channel at a high speed can flow out more smoothly, the wind outlet channel is gradually expanded outwards from the cross-flow wind wheel 100, the area of the wind outlet area can be further enlarged, and when the cross-flow wind wheel 100 rotates at a high speed, excessive noise cannot be generated when the airflow flows out from the outer end of the wind outlet channel.

Because the rotation direction of the cross-flow wind wheel 100 is fixed in the working process, the cross-flow wind wheel firstly enters the volute guide plate 210 and then passes through the auxiliary guide plate 220, and when the cross-flow wind wheel 100 passes through the auxiliary guide plate 220, part of the airflow is still driven, so that the part of the airflow collides with one side edge of the auxiliary guide plate 220 close to the cross-flow wind wheel 100 to generate noise; the arc plate 221 is extended along the direction of the continuous rotation of the cross-flow wind wheel 100 at the corresponding position of the side edge of the auxiliary guide plate 220, which can guide the airflow, thereby reducing or even eliminating the noise generated when the cross-flow wind wheel 100 rotates.

A heat exchanger 230 is arranged in the air guide structure. The heat exchanger 230 has many specific embodiments, and can adjust the temperature of the airflow passing through the air guide structure, for example, it can be matched with an air conditioner external unit to make the air outlet device have the better temperature adjustment function of the air conditioner, and for example, it can be matched with a heating device to heat the airflow, and has the function of air outlet and warm air; as shown in fig. 5, the heat exchanger 230 is specifically an arc plate, the arc plate is provided with an air inlet hollow structure, the heat exchanger 230 blocks an air inlet of the air guide structure, and external air is sucked into the cross-flow wind wheel 100 through the heat exchanger 230 under the driving of the cross-flow wind wheel 100, so that the temperature adjustment operation of the airflow is realized.

As shown in fig. 1-7, the air duct layer structure is annular, and is a layered structure formed by stacking two layers of air guiding grid plates 300 up and down; the air outlet array mechanism 140 is a tubular cover and is arranged on the outer side of the air guide structure. The air outlet array mechanism 140 is integrally tubular, and on one hand, internal structures such as the cross-flow wind wheel 100 and the air guide structure in the air outlet equipment are covered, so that the effect of protecting the internal structure of the air outlet equipment is achieved, and safety accidents caused by the fact that a user stretches limbs into the air outlet equipment can be avoided; on the other hand air-out array mechanism 140 includes that the multilayer can level pivoted wind channel layer structure alone, can make like this air-out array mechanism 140 can not only realize the adjustment of horizontal air-out direction, also can realize the regulation of different air-out heights according to the user's demand.

The air guide grid plate 300 comprises an annular plate 310; the annular plate 310 is divided into an upper annular plate and a lower annular plate; the upper annular plate is provided with the limiting column 311, and the lower annular plate is provided with a limiting part. The air guide grille can only adopt a single layer of the annular plate 310, the top surface of the single layer of the annular plate 310 is provided with the limiting column 311, the bottom surface of the single layer of the annular plate 310 is provided with the limiting part, but the air channel structure 320 of the air outlet array mechanism 140 formed by sequentially clamping and connecting the single layer of the annular plate 310 has narrow space and is not beneficial to air outlet; therefore, the air guide grid plate 300 at least adopts two annular plates 310, and the layer gap between the two annular plates 310 can increase the air outlet space, thereby improving the air outlet effect of the air outlet array mechanism 140.

As shown in fig. 6 and 7, the limiting part is a limiting through hole 312; the limiting through holes 312 are strip-shaped; one end of the limiting column 311 is connected with the upper annular plate, the other end of the limiting column 311 penetrates through the limiting through hole 312, and the limiting column 311 is limited and arranged in the limiting through hole 312. The limiting column 311 is connected with the limiting part in a clamping manner, so that the adjacent air duct layer structures can be connected; when spacing portion is the bar, spacing post 311 has certain removal space at the horizontal plane to make adjacent wind channel layer structure is at the linkage in-process, also can realize the relative rotation within a certain limit each other, makes the air-out swing form of air-out array mechanism 140 is more diversified.

The stopper column 311 includes: at least two resilient arms 313 and a back-off boss 315; the inverted boss 315 is wedge-shaped and includes a thin end and a thick end; an expansion gap 314 is arranged between the elastic arms 313; one end of the elastic arm 313 is connected with the upper annular plate, and the other end is connected with the thick end of the inverted boss 315. After the two adjacent air duct layer structures are stacked together up and down, the elastic arm 313 of the lower layer penetrates through the limiting through groove of the upper layer, and the bottom of the thick end of the inverted boss 315 is pressed on the top surface of the limiting through hole 312, so that the limiting column 311 can not be pulled out easily in the vertical direction; the elastic arm 313 and the expansion gap 314 enable the elastic arm 313 to be tightened within a certain range, so that the limiting post 311 can be naturally unfolded after passing through the limiting through hole 312, and the limiting post 311 and the limiting through hole 312 can be conveniently detached and separated under the action of external force; the inverted boss 315 not only limits the limiting post 311 in the vertical direction, but also facilitates the limiting post 311 to pass through the limiting through hole 312.

The annular plate 310 is provided with an air duct structure 320; the air duct structure 320 communicates the inner ring area of the annular plate 310 with the area outside the outer ring of the annular plate 310 from opposite directions. The cross-flow wind wheel 100 and the wind guide structure are installed in the inner ring area of the annular plate 310, and when the cross-flow wind wheel 100 rotates, airflow flows out from the inner ring area of the annular plate 310 to the periphery of the air outlet device along the air duct structure 320; the arrangement of the air duct structure 320 on the annular plate 310 can limit the direction of the airflow radiating from the inner annular region to the periphery, and meanwhile, the air duct structure 320 rotates with the annular plate 310, so that the direction of the airflow can be quickly and conveniently adjusted.

The inner ring edge of the annular plate 310 is circular, and the outer ring edge thereof is oval. The air channel structure 320 is arranged on the annular plate 310, so that the lengths of the air channel structures 320 at different positions are arranged according to the widths of the corresponding positions of the annular plate 310; the annular plates 310 are arranged to be oval rings with different widths at different positions, so that the lengths of the air duct structures 320 are not different, and when the tubular wind wheel 100 is rotated at a fixed speed, the turbulence degree of the air flow flowing out of each air duct structure 320 is related to the length of the air duct structure 320, so that the annular plates 310 are arranged to be oval rings or other shapes with different widths, so that the air outlet turbulence degree of the air outlet equipment is more diversified, and can be adjusted or combined according to user requirements.

Alternatively, the inner circular edge of the annular plate 310 is inscribed in an inner circle, the outer circular edge thereof is circumscribed on an outer circle, and the center of the inner circle and the center of the outer circle are not coincident in the normal direction of the annular plate 310. The inner ring edge and the outer ring edge have various shapes, can be polygonal rings or regular circles, and are necessarily inscribed or circumscribed into a virtual circle no matter what the shapes of the inner ring edge and the outer ring edge are, and the corresponding circles are inner circles or outer circles respectively; the annular plate 310 is annular, that is, the inner circle is necessarily smaller than the outer circle, and the centers of the inner circle and the outer circle are not coincident, that is, the widths of the annular edge of the annular plate 310 are limited to be equal or unequal, but not completely equal, so that the length of the air duct structure 320 for setting the width of the annular edge of the annular plate 310 is changed, and the air outlet parameters can be changed according to the rotation of the annular plate 310.

The lower surface of the annular plate 310 vertically extends downwards to form an air duct plate 320, and a plurality of air duct plates 320 are distributed at intervals with the lower surface of the annular plate 310. The specific arrangement mode of the air duct structure 320 is various, and the air duct structure 320 is a tubular structure; in the scheme, a simplified scheme is adopted, and the air duct structure 320 is a pipeline structure formed by combining the air duct plates 320 on two sides and the two annular plates 310 adjacent up and down, so that the production and manufacturing cost of the air guide grid plate 300 is lower, and the production effect can be improved; in addition, the air duct plate 320 is arranged on the lower surface of the annular plate 310, so that the groove-shaped structure of the annular plate 310 is arranged in an inverted manner, dust is not easy to accumulate, the dust can fall on the upper surface of the annular plate 310 more easily, and the upper surface of the annular plate 310 can be cleaned more easily than the lower surface when the annular plate is cleaned. The air channel structure 320 may also be disposed on the upper surface of the annular plate 310 or between layers of the annular plate 310.

After the driving mechanism is additionally arranged in the air outlet array mechanism 140, the air outlet array mechanism 140 can realize automatic driving control. The adjacent air duct layer structures in the air outlet array mechanism 140 are connected with the limiting part through the limiting column 311 in a clamping manner, so that when the driving mechanism drives any one layer of the air duct layer structure to rotate, other air duct layer structures can be linked with the air duct layer structure; according to the air outlet equipment, the single or a small number of driving mechanisms are arranged, so that the integral rotation of the air outlet array mechanism 140 can be realized, the structure is simpler, and the production and use cost is lower.

The supporting frame is connected with the supporting columns 330, so that the supporting columns 330 can be stably supported between the air duct layer structures; in addition, the supporting rod 341 can rotate in the movable hole, and when it rotates, the supporting rod drives the fixed arm to swing, so that the supporting column 330 and the outlet array mechanism 140 can be quickly separated or assembled.

The support frame includes: at least three support rods 341 are disposed in the inner region of the outlet array mechanism 140. The support frame is arranged in the inner area of the air outlet array mechanism 140, so that the whole structure of the air outlet equipment is more compact; in order to improve the structural stability of the supporting frame, when the number of the supporting rods 341 is increased to more than three, the rotating bracket 342 assembles a plurality of supporting rods 341 at the top and/or the bottom of the supporting frame, the radial size of the supporting mechanism becomes large and the supporting mechanism cannot be placed in the inner area of the air outlet array mechanism 140, and how to assemble or disassemble the supporting mechanism in the pure array mechanism is a technical difficulty, so a design scheme that the supporting rods 341 can rotate is adopted; when the supporting rod 341 rotates, the supporting column 330 is swung to the inner side area of the supporting frame by the fixing arm, and at this time, the supporting mechanism vertically moves in the inner area of the air outlet array mechanism 140, and does not collide with the air duct layer structure; therefore, the support mechanism adopts a skillful rotary folding structure, so that the radial dimension of the support mechanism can be quickly adjusted according to the installation or disassembly requirement, and the assembly and disassembly operations of the air outlet equipment are simplified.

As shown in fig. 8, two ends of the supporting column 330 are provided with balls 331, and when the air duct layer structures are stacked up and down, the balls 331 of the supporting column 330 between the adjacent air duct layer structures are in sliding fit with the air duct layer structures at corresponding positions. The sliding friction between one end of the supporting column 330 and the surface point surface of the air duct layer structure is changed into rolling friction, so that the friction resistance between the air duct layer structures can be reduced, and the air duct layer structure can be driven to rotate more smoothly and flexibly.
