Fig. 20 is a schematic front view of a laminar flow fan 110 with a drive disk 305 having a flat surface. Fig. 21 is a schematic perspective view of another perspective of the laminar flow fan 110 shown in fig. 20. In a preferred embodiment, an inverted conical protrusion 353 is further provided on a side surface of the driving disk 305 adjacent to the annular disk 301, and the inverted conical protrusion 353 can effectively guide the air entering the laminar flow fan 300 through the air inlet channel 302 into a gap between the disks, thereby improving the efficiency of forming laminar air.
Fig. 22 is a schematic view showing air circulation of the laminar flow fan 110 shown in fig. 20, in which air inlet passages 302 are formed at the centers of a plurality of annular disks 301 to allow air outside the laminar flow fan 300 to enter; a plurality of discharge ports 303 are formed in gaps between the plurality of annular disks 301 to blow out laminar air.
The connection 306 of the laminar flow fan 300 may be a blade 361, a connection rod 362, or the like.
Fig. 23 is a schematic cross-sectional view of the laminar flow fan 110 shown in fig. 20. In this embodiment, the connecting member 306 is a blade 361, and the cross section of the blade 361 has two curves sequentially arranged along the rotation direction of the annular disc 301, and the length of the chord 373 of the two curves has a linear relationship with the air volume of the laminar flow fan 110, so that the air volume of the laminar flow fan 110 can be greatly increased by increasing the length of the chord 373, and the laminar flow air circulation is promoted. It should be noted that the two curves may be arcs, non-arcs, straight lines, and the like, and the straight line may be a special curve. The length of the chord line 373 may be the distance between the two ends of the two curves, when the distance between the two ends of the two curves is the same. When the distances between the two end points of the two curves are different, if the two ends of the two curves are not intersected, the length of the chord line 373 may be the length of the connecting line of the middle points of the curves of the cross section of the blade 361 except the two curves; if only one end of the two curves intersects, the length of the chord line 373 may be the length of the line connecting the midpoint of the cross-section of the vane 361 except for the two curves and the end point of the intersection of the two curves.
In a preferred embodiment, the vanes 361 are plural and are evenly spaced throughout the drive disk 305 and the plurality of annular disks 301.

Fig. 24 is a schematic diagram showing the relationship between the length of the chord 373 and the wind pressure of the laminar flow fan 110 shown in fig. 20 when the outer diameter, the inner diameter, the number of layers, the pitch, the thickness, the installation angle of the blades 361, and the rotation speed of the motor 400 are all kept constant, wherein the abscissa axis refers to the length of the chord 373 of the blades 361, and the wind pressure refers to the pressure difference between the outlet 303 and the inlet of the air inlet channel 302. Note that the outer diameter of the annular disk 301 is the radius of its outer circumference, and the inner diameter is the radius of its inner circumference. The air boundary layer 304 rotates from inside to outside to form laminar wind, which moves centrifugally and thus leaves the outlet 303 at a higher velocity than the air entering the air inlet channel 302. The pressure difference between the outlet 303 and the inlet of the air intake channel 302 is the wind pressure, and the length of the chord 373 is in linear relation with the wind pressure. The wind pressure of the laminar flow fan 110 can be greatly improved by increasing the length of the chord 373, and the comprehensive performance of the laminar flow fan 110 is effectively guaranteed.
Considering the limited space inherent in the integrated air conditioner 100, there is a certain constraint on the overall occupied volume of the laminar flow fan 110. Specifically, considering that the thickness of the laminar flow fan 110 is not too large, the number of the annular disks 301, the distance between two adjacent annular disks 301, and the thickness of the annular disks 301 may be correspondingly constrained; the outer diameter of the annular disk 301 may be correspondingly constrained in view of the lateral footprint of the laminar flow fan 110 not being too large. For example, the outer diameter of each annular disc 301 may be set to 170mm to 180mm, and the inner diameter of each annular disc 301 is set to 110mm to 120mm, so that the air volume may be effectively increased, and the air outlet of the laminar flow fan 110 is ensured to meet the use requirements of users. In the case where the outer diameter and the inner diameter of the annular disk 301 are constant, although the chord line is constantThe longer 373 is, the larger the wind volume and the wind pressure of the laminar flow fan 110 are, but the length of the chord 373 is also restricted to a certain extent, so as to avoid the blade 361 from excessively penetrating the annular disc 301, which results in the stability reduction of the laminar flow fan 110. In summary, the length of the chord 373 can be set to the maximum range that can be achieved, so that the wind volume and the wind pressure of the laminar flow fan 110 can meet the use requirements of users. In a preferred embodiment, the annular disk 301 has an outer diameter of 175mm, an inner diameter of 115mm, 8 layers, a pitch of 13.75mm, a thickness of 2mm, a blade 361 mounted at an angle of 25.5 °, and a motor 400 rotating at 1000rpm, it has been found that the wind volume and pressure are both greatly increased and substantially linear after increasing the length of the chord 373. The length of the chord 373 is set to a maximum range of 40mm to 42mm that can be achieved while ensuring the stability of the laminar flow fan 110. Moreover, when the length of the chord 373 is set to 42mm, the air volume of the laminar flow fan 110 can reach 1741m3And h, the wind pressure can reach 118.9Pa, and the use requirements of users can be completely met.
In some embodiments, the blade 361 may be a double arc blade 310, the cross section of which has a double arc convex toward the direction of rotation of the annular disk 301, and includes an inner arc 371 and a back arc 372 arranged in sequence along the direction of rotation of the annular disk 301, and the inner arc 371 and the back arc 372 have the same center and are arranged in parallel. Fig. 25 is a schematic cross-sectional view of a laminar flow fan 110 having a double-arc blade 310. In a preferred embodiment, the outer diameter of each annular disc 301 is 170mm to 180mm, the inner diameter of each annular disc 301 is 110mm to 120mm, the difference between the outer diameter and the inner diameter of each annular disc 301 is about 60mm, the distance between the two ends of the inner arc 371 and the distance between the two ends of the back arc 372 are the same, the length of the chord line 373 is the distance between the two ends of the inner arc 371 or the back arc 372 and is set to 40mm to 42mm, so that the two ends of the inner arc 371 and the back arc 372 are respectively 10mm away from the inner circumference and the outer circumference of the annular disc 301, and the length of the chord line 373 is set to the maximum range which can be reached under the premise of ensuring the stability of the laminar flow fan 110, so that the air volume and the air pressure of the laminar flow fan 110 can meet the use requirements of users.
Fig. 26 is a schematic view showing the relationship between the installation angle α of the bi-arc blade 310 and the air volume and the air pressure when the outer diameter, the inner diameter, the number of layers, the pitch, the thickness, the chord length of the bi-arc blade 310 and the rotation speed of the motor 400 of the annular disk 301 are all kept constant, and the abscissa axis refers to the installation angle of the bi-arc blade 310, that is, the included angle formed by a chord line 373 between two end points of the inner arc 371 and a connecting line 374 passing through the midpoint of the chord line 373 and the central axis of the annular disk 301 on the same cross section of the bi-arc blade 310 and the annular disk 301. In a preferred embodiment, the annular disc 301 has an outer diameter of 175mm, an inner diameter of 115mm, 8 layers, a pitch of 13.75mm, a thickness of 2mm, a chord length of the bi-arc blade 310 of 35mm, and a rotation speed of the motor 400 of 1000rpm, and the installation angle α of the bi-arc blade 310 may be set to-5 ° to 55 ° in consideration of the air volume and the wind pressure. Note that, when the chord line 373 and the connecting line 374 are arranged in this order in the direction in which the annular disk 301 rotates, the installation angle α is a positive number; the installation angle α is negative when the connection line 374 and the chord line 373 are arranged in this order in the direction of rotation of the annular disk 301.

In other embodiments, the blade 361 may be an aviation blade 320, the cross section of which has a double arc convex toward the direction of rotation of the annular disk 301, and the double arc includes an inner arc 371 and a back arc 372 arranged in sequence along the direction of rotation of the annular disk 301, and the inner arc 371 and the back arc 372 have different centers and both ends intersect. Fig. 27 is a cross-sectional schematic view of a laminar flow fan 110 having aero blades 320.
Fig. 28 is a schematic diagram of the relationship between the installation angle α of the aviation blade 320 and the air volume and the air pressure when the outer diameter, the inner diameter, the number of layers, the pitch, the thickness, the chord length of the aviation blade 320 and the rotation speed of the motor 400 of the laminar flow fan 110 shown in fig. 27 are all kept constant, and the abscissa axis refers to the installation angle of the aviation blade 320, that is, the included angle formed by the chord line 373 between the two end points of the inner arc 371 or the back arc 372 and the connecting line 374 passing through the midpoint of the chord line 373 and the central axis of the annular disc 301 on the same cross section of the aviation blade 320 and the annular disc 301. In a preferred embodiment, the annular disc 301 has an outer diameter of 175mm, an inner diameter of 115mm, 8 layers, a pitch of 13.75mm, a thickness of 2mm, a chord length of the aero blade 320 of 35mm, and a rotation speed of the motor 400 of 1000rpm, and the installation angle α of the aero blade 320 may be set to-50 ° to 15 ° in consideration of the air volume and the wind pressure. This installation angle compromises laminar flow fan 110's amount of wind and wind pressure, effectively ensures laminar flow fan 110's comprehensive properties, makes laminar flow fan 110's air-out also can satisfy user's user demand when the wind pressure is big, further promotes user's use and experiences.
The annular disk 301 of the laminar flow fan 300 may also be arranged according to one or more of the following configurations: the distance between two adjacent annular disks 301 is gradually increased along the flowing direction of air in the air inlet channel 302; the inner diameters of the plurality of annular disks 301 are gradually reduced along the flowing direction of the airflow in the air inlet channel 302; each annular disc 301 is an arc-shaped disc that gradually approaches the drive disc 305 from the inside to the outside.
In some embodiments, the plurality of annular disks 301 of the laminar flow fan 300 are arranged in parallel at intervals with the same central axis, and the interval between two adjacent annular disks 301 is gradually increased along the direction in which air flows in the air intake passage 302. Fig. 29 is a schematic front view of the laminar flow fan 110 in which the pitch of the annular disks 301 is gradually changed. The inventor finds that, through multiple experiments, as the distance between two adjacent annular disks 301 gradually increases along the flowing direction of air in the air inlet channel 302, the air volume of the laminar flow fan 110 can be effectively increased, so that the air outlet of the laminar flow fan 110 meets the use requirement of a user.

As shown in fig. 31, when all the above mentioned parameters are kept unchanged, the distance between every two adjacent annular disks 301 in the plurality of annular disks 301 gradually changes from bottom to top, which has a large influence on the air volume and a small influence on the air pressure; when the variation of the distance between two adjacent annular disks 301 along the direction from bottom to top, which is represented by the abscissa axis, is a positive number, it is described that the distance between every two adjacent annular disks 301 in the plurality of annular disks 301 gradually increases from bottom to top; when the variation of the spacing between two adjacent annular disks 301 along the direction from bottom to top, which is represented by the abscissa axis, is a negative number, it indicates that the spacing between every two adjacent annular disks 301 in the plurality of annular disks 301 gradually decreases from bottom to top. Therefore, as can be seen from fig. 31, when the variation amount of the pitch between every two adjacent annular disks 301 of the plurality of annular disks 301 is-1 mm, 1mm and 2mm, the air volume and the air pressure of the laminar flow fan 110 are greatly improved.
As mentioned above, the connecting member 306 of the laminar flow fan 300 in the embodiment of the present invention may be a connecting rod 362. Fig. 30 is a schematic perspective view of the laminar flow fan 110 shown in fig. 29. The connecting rods 362 may be a plurality of rods, and are uniformly spaced throughout the edge portions of the drive disk 305 and the plurality of annular disks 301. The connecting rods 362 uniformly penetrate through the edge portions of the driving disk 305 and the annular disks 301 at intervals, so that the connection relationship between the driving disk 305 and the annular disks 301 can be ensured to be stable, and further, when the motor 400 drives the driving disk 305 to rotate, the driving disk 305 can stably drive the annular disks 301 to rotate, and the working reliability of the laminar flow fan 110 is improved.

That is, the target air volume of the laminar flow fan 110 may be obtained first, and then the rotation speed of the motor 400 may be determined according to a linear relationship between the target air volume and the rotation speed of the motor 400. The target air volume may be obtained by an input operation of the user. In a preferred embodiment, the outer diameter of the annular disc 301 is 175mm, the inner diameter is 115mm, the number of layers is 8, and the distance between two adjacent annular discs 301 is sequentially set from bottom to top: 13.75mm, 14.75mm, 15.75mm, 16.75mm, 17.75mm, 18.75mm, 19.75mm, when the thickness is 2mm, the linear relation between the rotating speed of the motor 400 and the air volume of the laminar flow fan 110 is more obvious.
In some embodiments, the inner diameter of the plurality of annular disks 301 of the laminar flow fan 300 of the present invention gradually decreases along the direction of the airflow flowing in the air intake channel 302.

As shown in fig. 33, when the above mentioned parameters are all kept unchanged, the inner diameters of the plurality of annular disks 301 gradually change from bottom to top, which has a large influence on the air volume and a small influence on the air pressure. When the variation of the inner diameter of each annular disc 301 represented by the abscissa axis and the inner diameter of the adjacent annular disc 301 below is a positive number, it indicates that the inner diameters of the plurality of annular discs 301 gradually increase from bottom to top; when the variation of the inner diameter of each annular disc 301 and the inner diameter of the adjacent annular disc 301 below is negative, the inner diameters of the annular discs 301 gradually decrease from bottom to top.

In some embodiments, the annular disc 301 of the laminar flow fan 300 is an arcuate disc that gradually approaches the drive disc 305 from the inside to the outside. Taking the laminar flow fan 300 arranged at the upper part in the casing 200 as an example, each annular disc 301 is set to be an arc-shaped disc which gradually rises from inside to outside and protrudes upwards, so that the angle of the external air entering the laminar flow fan 300 is more consistent with the flow of the fluid, the external air entering the laminar flow fan 300 is more facilitated, the air volume loss is effectively reduced, and the air outlet of the laminar flow fan 110 is ensured to meet the use requirements of users. Fig. 34 is a schematic view of the central angle θ of the inner and outer diameter connecting lines of the plurality of annular disks 301 on the same longitudinal section passing through the central axis. Fig. 35 is a schematic diagram of the relationship between the central angle θ and the wind volume and wind pressure when the outer diameter, the number of layers, the pitch, the thickness of the annular disc 301 and the rotation speed of the motor 400 are all kept unchanged. As shown in fig. 35, when each of the above-mentioned parameters is kept constant, as the central angle θ is gradually increased, the air volume is increased and then decreased, and the air pressure is slightly increased. In a preferred embodiment, the annular disks 301 have an outer diameter of 175mm, a number of 10 layers, a pitch of 13.75mm, a thickness of 2mm, and a rotation speed of the motor 400 of 1000rpm, and the central angle θ may be set to 9 ° to 30 ° in consideration of the air volume and the wind pressure.
