Description
Technical Field
The invention relates to a cross-flow wind wheel, in particular to a low-cost and high-efficiency cross-flow wind wheel.
Background
In order to facilitate punching processing of the cross flow wind wheel blade, the thickness of the cross flow wind wheel blade in an air conditioner in the market at present is generally in the range of 0.8mm to 1.2mm, but the whole mass of the cross flow wind wheel is increased due to the fact that the thickness of the blade is large, and the load of a motor is increased. Chinese patent document No. CN100501170C discloses a cross-flow fan impeller in 6 months and 17 days 2009, specifically discloses: the device comprises an impeller left end cover, an impeller right end cover, a plurality of middle spacing rings and a plurality of blades arranged between the middle spacing rings or between the middle spacing rings and the left end cover and the right end cover, wherein the blades are distributed according to the blade inclination angle beta=21+/-2 degrees; on the cross section of the blade, the width L of the blade is 12+/-2 mm, the chord height h of the blade is 2.5+/-0.8 mm, and the maximum thickness t of the blade is 1.3+/-0.5 mm. The thickness of the blade in this structure is large, resulting in an increase in the overall mass and an increase in the motor load, and therefore, further improvement is necessary.
Disclosure of Invention
The invention aims to provide a low-cost high-efficiency cross flow wind wheel with simple and reasonable structure, light weight and low energy consumption, so as to overcome the defects in the prior art.
According to this purpose design a low-cost efficient cross flow wind wheel, including the base member, and annular equipartition is on the blade on the base member, its characterized in that: the outer end and/or the inner end of the blade are/is provided with an end head, and the maximum thickness d1 of the blade has the following range: d1 is more than or equal to 0.45mm and less than or equal to 0.65mm, and the relation between the maximum inscribed circle diameter d2 of the outer end head and d1 is as follows: d2-d1 is less than or equal to 0.2mm and less than or equal to 0.6mm.
The maximum thickness d1 of the blade is 0.5mm.
The cross section of the end head is circular, polygonal or irregularly-shaped.
The blades are curved in the shape of a circular arc, and the radian is 60 DEG.ltoreq.alpha.ltoreq.65 DEG, preferably 61 DEG or 62 deg.
The end of the blade provided with the end head is bent towards the rotation direction of the basal body
The maximum thickness d1 of the blade is reduced to between 0.45 and 0.65mm, preferably 0.5mm, and the linear cutting hole is easy to deviate from the blade body in the process of processing the cavity of the blade due to smaller thickness of the blade, so that the problem that the linear cutting hole deviates from the blade 2 body in the process of processing the linear cutting hole can be effectively avoided by arranging the end head and processing the linear cutting hole at the end head, the processing efficiency and quality are improved, the through-flow wind wheel is easy to punch and process the blade in the process of developing a mould, and the problem that the blade is difficult to process due to too small thickness is solved; in addition, the thickness of each blade is reduced, so that the overall mass of the cross flow wind wheel is reduced, the load of the motor is reduced, and the energy consumption is reduced.

Referring to fig. 1 and 2, the low-cost high-efficiency cross-flow wind wheel comprises a base body 1 and blades 2 which are annularly and uniformly distributed on the base body 1; the outer end (and/or the inner end) of the blade 2 is integrally formed with a tip 3, the maximum thickness d1 of the blade 2 is 0.5mm, and the relationship between the maximum inscribed circle diameter d2 and d1 of the tip 3 of the outer end is: d2-d1 is less than or equal to 0.2mm and less than or equal to 0.6mm. Compared with the traditional structure, the maximum thickness d1 of the blade 2 is reduced to 0.45-0.65 mm, preferably 0.5mm, and the thickness of the blade 2 in the structure is smaller, and the linear cutting hole is easy to deviate from the blade body in the process of processing the blade cavity, so that the linear cutting hole is processed at the position of the end head 3 by arranging the end head 3, the problem that the linear cutting hole deviates from the blade 2 body is effectively avoided, and the processing efficiency and quality are improved; in addition, the thickness of each blade 2 is reduced, so that the overall mass of the cross flow wind wheel is reduced, the load of the motor is reduced, and the energy consumption is reduced.
Further, the cross section of the end head 3 is circular, the whole end head is spherical, and the arc surface of the end head can avoid direct collision with air, so that wind resistance can be reduced; in addition, the cross section of the end head 3 can be polygonal or irregularly shaped.
Further, the end of the blade 2 provided with the tip 3 is bent in the rotational direction of the base 1 so as to generate a sufficiently large air volume.
Further, the blade 2 is curved in a circular arc shape, and the arc is 61 °.
The foregoing is a preferred embodiment of the invention showing and describing the general principles, features and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the foregoing embodiments, which have been described in the foregoing description merely illustrates the principles of the invention, and that various changes and modifications may be made therein without departing from the spirit and scope of the invention, which is defined in the appended claims.
