In addition, technical solutions between various embodiments may be combined with each other, but must be realized by a person skilled in the art, and when the technical solutions are contradictory or cannot be realized, such a combination should not be considered to exist, and is not within the protection scope of the present invention.
The invention provides a stationary blade wind wheel, a cabinet air conditioner and an air conditioner with the stationary blade wind wheel.
In an embodiment of the present invention, as shown in fig. 1 and 2, a stationary blade wind wheel 10 is mounted on a cabinet air conditioner, the stationary blade wind wheel 10 includes a hub 11 and a blade 12 mounted on the hub 11, the blade 12 includes a blade root portion 12b and a blade body portion 12a, one end of the blade root portion 12b is connected to the hub 11, the other end of the blade root portion 12b is connected to the blade body portion 12a, and a thickness of the blade root portion 12b gradually decreases in a direction toward the blade body portion 12 a.
Specifically, an axial flow fan is arranged in the cabinet air conditioner, the axial flow fan is provided with a motor, a movable blade wind wheel and a housing, the movable blade wind wheel is installed at an air inlet end of the housing, a stationary blade wind wheel 10 is installed at an air outlet end of the housing, and the motor is connected with the movable blade wind wheel. When the axial flow fan operates, the motor drives the movable blade wind wheel to rotate, the movable blade wind wheel guides air outside the cabinet air conditioner to the stationary blade wind wheel 10, and the air is rectified by the stationary blade wind wheel 10 and then blown to an air outlet frame of the cabinet air conditioner and finally guided out of the air outlet frame.
Because the space between two adjacent blade roots 12b is small, when the airflow passes through the blade roots 12b, noise is easy to generate; especially, when the air is guided out by the movable vane wind wheel, the airflow is messy, the flow velocity of the airflow is sometimes large or small between the two blade roots 12b, and when the flow velocity is too large, noise is generated. In the embodiment, referring to fig. 3, since the root portion 12b of the fan blade 12 is tapered, when the airflow flows through the fan blade 12, the fan blade 12 has a function of accommodating the air, and the air has a tendency of flowing toward the joint of the blade root portion 12b and the blade body portion 12a, so that the fan blade 12 can reconcile the airflow with a messy flowing direction and the airflow with inconsistent flow velocity on one hand, so that the airflow flows out from the stationary blade wind wheel 10 at a uniform flow velocity and uniform direction, and thus, the noise generated by the airflow is correspondingly reduced; on the other hand, under the stopping action of the fan blades 12, the effective air outlet area of the air outlet end of the outer cover is smaller, which is equivalent to the pressurization of the fan blades 12 on the airflow, so that the airflow guided out by the stationary blade wind wheel 10 is blown farther.
In order to prove the noise reduction effect of the fan blade 12, the following experimental comparisons are made:
TABLE 1 is the comparison table of the experimental parameters of the prior stator blade wind wheel arranged in the air conditioner
Table 2 is a table comparing parameters of the first experiment in which the stationary blade wind wheel of the invention is arranged in the cabinet air conditioner
Table 3 is a table comparing parameters of the second experiment in which the stationary blade wind wheel of the invention is arranged in the cabinet air conditioner
It can be seen from tables 1 and 2 that, under the same motor speed, the noise of the cabinet air conditioner adopting the stationary blade wind wheel of the invention is 2dB lower than that of the existing cabinet air conditioner. It can be seen from tables 2 and 3 that the noise level is independent of the power level. In addition, even if the power of the cabinet air conditioner adopting the stator blade wind wheel is higher, the noise is lower (refer to tables 1 and 2).
According to the technical scheme, a blade root part 12b is additionally arranged between a blade body part 12a of a fan blade 12 and a hub 11, the thickness of the blade root part 12b is gradually reduced in the extending direction of the fan blade 12, airflow gradually flows towards the joint of the blade root part 12b and the blade body part 12a when flowing between the two blade root parts 12b, and a stationary blade wind wheel 10 integrates the airflow again, so that the air outlet of an axial flow fan is more uniform, and the noise is lower.
With continued reference to fig. 3, on the basis of the above embodiment, in order to make the integrating force of the fan blade 12 on the airflow greater and make the flow velocity of the airflow more uniform, in the present embodiment, the thickness of the blade body portion 12a gradually increases in a direction away from the blade root portion 12 b. Thus, when the movable blade wind wheel guides the airflow to the stationary blade wind wheel 10, the airflow is divided into two parts in the radial direction of the stationary blade wind wheel 10, one part is located between two adjacent blade parts 12a, and the other part is located between two adjacent blade roots 12b, the air between the two blade roots 12b can flow towards the joint of the blade root 12b and the blade part 12a, and the air between the two blade parts 12a can also flow towards the joint, so that the rectification effect of the blade 12 is better.
Referring to fig. 2 and 3, in another preferred embodiment, in order to further increase the flow straightening effect of the fan blade 12, the stationary blade wind wheel 10 further includes a tip portion 12c, the tip portion 12c is connected to the end of the blade body portion 12a, and the thickness of the tip portion 12c is gradually reduced in a direction away from the blade body portion 12 a. Therefore, when airflow enters the stationary blade wind wheel 10, the pressure intensity of the airflow on two sides of the same fan blade 12 may be inconsistent, and thus, the pressure intensity difference of the airflow can be reduced by the air leakage of the blade tip part 12c (the air leakage resistance of the blade tip part 12c is smaller), so that the flow velocity of the airflow is more uniform, and the noise is smaller. It should be noted that the stationary blade wind wheel 10 further includes a wheel casing 13 located at the periphery of the wind blade 12, the blade tip 12c may be partially connected to the wheel casing 13, or the tail end of the blade tip 12c may be integrally connected to the wheel casing 13, and in the above description, the beneficial effect of the blade tip 12c is that the blade tip 12c is partially connected to the wheel casing 13.
With continued reference to fig. 2 and 3, when the airflow passes through the fan blade 12, pressure is applied to the fan blade 12, and the fan blade 12 may deform after receiving the pressure, and even the fan blade 12 may swing back and forth, which may generate noise. In this embodiment, to avoid the above situation, the fan blade 12 is disposed in an arc shape extending along the blade root 12b toward the blade body 12 a. Therefore, the strength of the fan blade 12 is increased, and the fan blade 12 is not easy to deform or swing under the pressure of airflow.
Referring to fig. 3, 4 and 5, in a preferred embodiment, considering that the curvature of the fan blade 12 directly affects the rectification effect of the fan blade 12, the diameter of the shroud 13 of the stationary blade wind wheel 10 is D, and the fan blade 12 has a concave arc surface and a convex arc surface opposite to the concave arc surface. In the stator blade wind wheel 10, the number of the fan blades 12 cannot be too much or too little, and the space between the two fan blades 12 can be too much to be smaller, which is not beneficial to air outlet; the number of the blades is not too large, and the space between the two blades 12 is large due to too much number, which is not beneficial to rectification. The diameter of the convex arc determines the number of the fan blades 12, and the larger the bending curvature is, the smaller the number of the fan blades 12 is; the smaller the curvature of the curve, the greater the number of blades 12. In order to moderate the number of the fan blades 12 (7 to 11 pieces), the arc diameter formed by the convex arc surface is
Referring to fig. 1, 2 and 4, because the combination of the fan blades 12 with odd number can bring more performance advantages than the combination of the fan blades 12 with even number. If the number of the fan blades 12 is an even number and a symmetrical arrangement is formed, the balance of the fan blades 12 is difficult to adjust, and the fan blades 12 generate more resonances, so that the fan blades 12 cannot bear fatigue caused by resonances for a long time, and finally the fan blades 12 are broken. Therefore, in the present embodiment, the number of the fan blades 12 is odd.
Referring to fig. 3, considering that the stator blade vibrates when the airflow passes through the stator blade, the radial span of the blade root 12b in the stator blade wind wheel 10 often determines the strength of the blade 12. If the span of the blade body 12a is large and the span of the blade root 12b is small, the joint between the blade body 12a and the blade root 12b is easily broken along with the vibration of the fan blade 12. However, if the span of the blade body portion 12a is small and the span of the blade root portion 12b is large, the thickness reduction gradient of the blade root portion 12b is small, which is not favorable for rectification. In the present embodiment, in order to improve the overall strength of the fan blade 12 and ensure the flow rectification effect of the fan blade 12, the radial span of the stator blade wind wheel 10 is L, and the radial span of the blade root 12b in the stator blade wind wheel 10 is 0.2L to 0.4L.
With continued reference to fig. 4, considering thermal expansion and cold contraction, the end of the fan blade 12 cannot be too close to the wheel casing 13, and the fan blade cannot be too far away, which may cause the fan blade 12 to abut against the wheel casing 13, causing deformation of the wheel casing 13; too far away may cause air leakage between the wheel cover 13 and the ends of the fan blades 12, thereby affecting the flow straightening effect. In this embodiment, the diameter of the shroud 13 of the stator blade wind wheel 10 is D, and the distance between the axis of the hub 11 and the end of the fan blade 12 is D
Therefore, even if the fan blades 12 are expanded by heat, the tail ends of the fan blades 12 cannot be abutted against the inner wall of the wheel cover 13; in addition, the distance between the tail end of the fan blade 12 and the inner wall of the wheel cover 13 is not too large, and the fan blade ensures the wind shaping effect.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
