The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.
The following disclosure provides many different embodiments, or examples, for implementing different features of the invention. In order to simplify the disclosure of the present invention, the components and arrangements of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. Furthermore, the present invention may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. In addition, the present disclosure provides examples of various specific processes and materials, but one of ordinary skill in the art may recognize the applicability of other processes and/or the use of other materials.
Next, with reference to the drawings, an air duct member 20 for a cross-flow wind wheel 10 according to an embodiment of the first aspect of the present invention is described.
As shown in fig. 1, the air duct member 20 includes: the duct body 21 and the flow blocking structure 22, in a cross section perpendicular to the axis of the cross-flow wind wheel 10 (for example, in the cross section shown in fig. 1), the duct body 21 includes a first volute portion 211 and a second volute portion 212 which are oppositely arranged, and a cross-flow duct 210 is defined between the first volute portion 211 and the second volute portion 212.
Referring to fig. 2, the first volute portion 211 includes a volute tongue 211a, and on the cross section, a perpendicular line L is drawn from the volute tongue 211a to the second volute portion 212, and the flow blocking structure 22 is disposed in the through-flow air duct 210 and located downstream of the perpendicular line L, that is, when the through-flow wind wheel 10 works, the airflow enters the through-flow air duct 210 from the air inlet of the through-flow air duct 210, flows through the through-flow air duct 210 to the position where the perpendicular line L is disposed, and then flows through the through-flow air duct 210 to the position where the flow blocking structure 22 is disposed.
It should be noted that the shortest one of all perpendicular lines from each point on the volute tongue 211a to the second volute section 212 is the perpendicular line L, or the perpendicular line of the minimum distance from the volute tongue 211a to the second volute section 212 is the perpendicular line L. Further, it is understood that a portion of the cross flow duct 210 at the position of the above-described perpendicular line L may be referred to as a throat portion 210a of the cross flow duct 210.
With reference to fig. 3, the flow blocking structure 22 includes at least two flow blocking portions 221, where the at least two flow blocking portions 221 are respectively disposed at two axial end portions of the cross flow wind duct 210 in the axial direction of the cross flow wind wheel 10, that is, at least one flow blocking portion 221 is respectively disposed at each of the two axial end portions of the cross flow wind duct 210 in the axial direction of the cross flow wind wheel 10. For example, in the example shown in fig. 3, when the axial direction of the cross flow wind wheel 10 is the left-right direction, the flow blocking structures 22 are respectively disposed at the left end and the right end of the cross flow wind duct 210, at least one flow blocking portion 221 is disposed at the left end of the cross flow wind duct 210, and at least one flow blocking portion 221 is disposed at the right end of the cross flow wind duct 210.
Therefore, according to the utility model discloses air duct component 20, both ends department through-flow wind channel 210 sets up and keeps off class structure 22, and keep off class structure 22 and locate the low reaches of throat 210a of through-flow wind channel 210, thereby make the air-out area of intermediate position department on the length direction (being the axial of through-flow wind wheel 10) of through-flow wind channel 210 great, can match great air-out wind speed, the air-out area of both ends department is less, can match less air-out wind speed, thereby the air load at the whole length within range of through-flow wind channel 210 is basically the same, gas flow is comparatively even, can improve the both ends department in through-flow wind channel 210 effectively and produce the air supply abnormal sound problem.
Some air conditioners in the related art adopt the cross-flow wind wheel to match the cross-flow air duct, however, in the working process of the cross-flow wind wheel, the air flow in the whole length range of the cross-flow air duct is not uniform, and the problem of air flow noise generated in the cross-flow air duct can be caused due to the non-uniform flow. The inventor finds that the length of the cross-flow wind wheel is smaller than that of the cross-flow wind channel 210, and is influenced by the two side wall surfaces of the cross-flow wind channel, the wind speed at the middle position in the length direction of the cross-flow wind channel (namely the axial direction of the cross-flow wind wheel) is larger, and the wind speed near the two side wall surfaces is smaller, but because the wind outlet areas of the cross-flow wind channel in the whole length direction are the same, the airflow loads in the whole length range of the cross-flow wind channel are different, the air flow is not uniform, so that discontinuous airflow sound is generated at the two sides of the cross-flow wind channel, and the problem of airflow noise is generated.
According to the air duct component 20 of the embodiment of the present invention, the two end portions of the through-flow air duct 210 are provided with the flow blocking structures 22, and the flow blocking structures 22 are located at the outer side of the throat portion 210a of the through-flow air duct 210, so that in the axial direction of the through-flow wind wheel 10, it can be ensured that the air outlet of the middle portion of the through-flow air duct 210 is not affected by the flow blocking structures 22, and it can have a larger air outlet area, thereby adapting to a larger air outlet speed, and the air outlet of the two end portions of the through-flow air duct 210 can be affected by the flow blocking structures 22, and can have a smaller air outlet area, thereby adapting to a smaller air outlet speed, so as to satisfy the requirement that the larger air outlet area in the middle is matched with the larger air outlet area, and the smaller air outlet area is matched with the smaller air outlet area at the two ends, so that it can be ensured that the air flow load in the whole, improve the problem of abnormal sound of airflow.
In some embodiments of the present invention, as shown in fig. 2 and 3, the flow blocking structure 22 is disposed on the first volute section 211 and/or the second volute section 212. That is, at least one of the first and second volute sections 211 and 212 is provided with the flow blocking structure 22. For example, in some embodiments, the flow blocking structures 22 may be provided only on the first volute section 211 and at both ends of the cross-flow duct 210. For another example, in some embodiments, the flow blocking structure 22 may be only disposed on the second volute portion 212 and located at two ends of the through-flow duct 210. For another example, in some embodiments, the flow blocking structures 22 may be respectively disposed on the first and second scroll casing portions 211 and 212, and the flow blocking structures 22 are respectively disposed at two end portions of the through-flow duct 210, in this embodiment, for example, the flow blocking structure 22 on the first scroll casing portion 211 may be located at one end portion of the through-flow duct 210, the flow blocking structure 22 on the second scroll casing portion 212 may be located at the other end portion of the through-flow duct 210, the flow blocking structure 22 on the first scroll casing portion 211 may be respectively located at two end portions of the through-flow duct 210, and/or the flow blocking structure 22 on the second scroll casing portion 212 may be respectively located at two end portions of the through-flow duct 210. Therefore, the flow blocking structure can be applied to different practical situations, meets the requirement for improving abnormal sound, and simplifies the arrangement mode of the flow blocking structure 22.
In some embodiments, the flow blocking structure 22 disposed on the first worm casing part 211 may be configured to be integrally formed with the first worm casing part 211, and the flow blocking structure 22 disposed on the second worm casing part 212 may also be configured to be integrally formed with the second worm casing part 212, thereby simplifying the assembly process. Of course, the present invention is not limited thereto, for example, in other embodiments of the present invention, the flow blocking structure 22 may be assembled and connected to the first worm casing portion 211 and/or the second worm casing portion 212, and so on, which will not be described herein. In addition, in other embodiments, the flow blocking structure 22 may not be disposed on the first worm casing portion 211 or the second worm casing portion 212, for example, the flow blocking structure 22 may also be disposed between the first worm casing portion 211 and the second worm casing portion 212 through other fixing structures, and so on, which are not described herein again.
In some embodiments of the present invention, as shown in fig. 2 and 3, two flow blocking portions 221 are provided at an outer end portion of the second volute portion 212 facing a side surface of the first volute portion 211, and the two flow blocking portions 221 are respectively located at both end portions of the second volute portion 212 in the axial direction of the cross-flow wind wheel 10. It should be noted that the outer end of the second volute section 212 refers to a portion of the second volute section 212 close to the air outlet 210b of the cross-flow duct 210. In addition, in this embodiment, the first volute portion 211 may or may not be provided with the flow blocking structure 22. In the following, only the first volute portion 211 without the flow blocking structure 22 will be described as an example, and it is obvious to those skilled in the art that after reading the technical solutions below, an embodiment in which the flow blocking structure 22 is also provided on the first volute portion 211 can be understood.
Therefore, the arrangement scheme of the flow blocking structure 22 is simple, and the outlet areas of the two ends of the air outlet 210b of the through-flow air duct 210 can be simply and effectively improved, so that the air outlet of the middle part of the air outlet 210b of the through-flow air duct 210 can be ensured not to be influenced by the flow blocking part 221, and the air outlet area can be larger, so that the air outlet speed is larger, the air outlet of the two ends of the air outlet 210b of the through-flow air duct 210 can be influenced by the flow blocking part 221, the air outlet area can be smaller, so that the air outlet speed is smaller, the requirements that the air speed at the middle is larger to match the air outlet area and the air speed at the two ends is smaller to match the air outlet area are smaller, so that the air flow load in the whole length range of the through-flow air duct 210 is basically the same, the air flow is more uniform, and the discontinuous sound air, improve the problem of abnormal sound of airflow.
In some embodiments of the present invention, as shown in fig. 2, the second volute section 212 includes a second straight line section 212a and a second flared section 212b, the second flared section 212b extends from an outer end of the second straight line section 212a toward a direction away from the first volute section 211, and both of the flow blocking portions 221 are disposed on the second straight line section 212a, it can be understood that, since the flow blocking portion 221 is located at an outer end portion of the second volute section 212, the flow blocking portion 221 should be disposed on a portion of the second straight line section 212a close to the second flared section 212 b. Therefore, the effect of the flow blocking part 221 on the airflow in the through-flow air duct 210 can be improved, and the problem of airflow noise can be improved better.
Of course, the present invention is not limited thereto, and in other embodiments of the present invention, the flow blocking portion 221 may also be disposed on the second flared section 212 b. Furthermore, the structure of the second volute section 212 is not limited thereto, for example, in some other embodiments of the present invention, the second volute section 212 may also include only the second straight section 212a, and not the second flared section 212b, and so on.
In addition, in some embodiments of the present invention, in order to match the structure of the second worm casing part 212, as shown in fig. 2, the first worm casing part 211 may be configured to include a first straight line 211b and a first flared section 211c, the first flared section 211c extends from the outer end of the first straight line 211b to a direction away from the second worm casing part 212, the worm tongue 211a is connected to the inner end of the first straight line 211b, and so on, which will not be described herein.
In some embodiments of the present invention, as shown in fig. 4, the maximum height of the flow blocking portion 221 in the direction perpendicular to the second straight line segment 212a is H, the diameter of the cross-flow wind wheel 10 is D, and H is greater than or equal to 3mm and less than or equal to 0.15D. That is, the maximum height of the flow blocking part 221 is equal to or less than 0.15 times the diameter of the cross-flow wind wheel 10, and the maximum height of the flow blocking part 221 is equal to or greater than 3 mm. This can avoid the problem of air volume attenuation due to the large maximum height of the baffle portion 221, and also avoid the problem of insignificant noise improvement effect due to the small maximum height of the baffle portion 221.
Here, it should be noted that the cross-sectional shape of the flow blocking portion 221 is not limited, and may be a regular shape or an irregular shape, for example, a rectangle shown in fig. 2, a triangle shown in fig. 4, a semicircle not shown, and the like, that is, the cross-sectional contour line of the flow blocking portion 221 may be a combination of straight line segments and/or curved line segments. Therefore, in each cross section of the baffle portion 221, a point of the baffle portion 221 farthest from the second straight line segment 212a is distant from the second straight line segment 212a by the maximum height H.
In some embodiments of the present invention, as shown in fig. 3, the axial length of the flow blocking portion 221 in the axial direction of the cross-flow wind wheel 10 is B, the axial length of the cross-flow wind wheel 10 is a, and B is greater than or equal to 5mm and less than or equal to 0.2A. That is, the length of the flow blocking portion 221 is equal to or less than 0.2 times the axial length of the cross-flow wind wheel 10, and the length of the flow blocking portion 221 is equal to or more than 5 mm. Therefore, the adverse effect of the larger length of the flow blocking part 221 on the middle of the through-flow air duct 210 can be avoided, and the problem of the unobvious noise improvement effect on two sides caused by the smaller length of the flow blocking part 221 can also be avoided. Note that the length of each baffle 221 may be equal to this value, but the lengths of the baffles 221 are not required to be equal to each other, and may be equal to or different from each other.
In some embodiments of the present invention, as shown in fig. 3, at least one flow blocking portion 221 is a continuous flow blocking portion that is continuous along the axial direction of the cross-flow wind wheel 10. For example, the right baffle 221 shown in fig. 3 is a continuous baffle that is continuous in the axial direction of the turbine rotor 10, that is, the baffle 221 is not continuous in the axial direction of the turbine rotor 10. Therefore, the processing is convenient, and the effect of improving abnormal sound is good.
Of course, the present invention is not limited thereto, and in other embodiments of the present invention, the at least one flow blocking portion 221 includes a plurality of sub flow blocking portions 2210 spaced apart from each other along the axial direction of the cross-flow wind wheel 10, for example, the left flow blocking portion 221 shown in fig. 3 is a structure interrupted along the axial direction of the cross-flow wind wheel 10, and includes a plurality of sub flow blocking portions 2210 spaced apart from each other along the axial direction of the cross-flow wind wheel 10, that is, the flow blocking portion 221 is interrupted along the axial direction of the cross-flow wind wheel 10, and is similar to the comb-teeth shape. Therefore, the blocking of the airflow can be reduced, and the air volume on the side can be improved to a certain extent while improving the abnormal sound.
In some embodiments of the present invention, as shown in fig. 3, the length direction of each flow blocking portion 221 is parallel to the axial direction of the cross flow wind wheel 10, so as to facilitate processing, and on the premise of the same projection length, the length of each flow blocking portion 221 can be shortened, thereby saving material. It should be noted that the flow blocking portion 221 according to the embodiment of the present invention is not limited to extend along a straight line, and may also extend along a curved line, a broken line, or the like, for example, when the flow blocking portion 221 extends along a curved line or a broken line, the extending direction of the connecting line of the two ends of the flow blocking portion 221 in the length direction is the length direction of the flow blocking portion 221. In addition, in other embodiments of the present invention, the length direction of the flow blocking portion 221 may not be parallel to the axial direction of the cross-flow wind wheel 10, for example, may also intersect with the axial direction of the cross-flow wind wheel 10 at a non-zero included angle.

For example, in some embodiments, cross-flow wind wheel 10 may be disposed at an air inlet of cross-flow duct 210.
Therefore, according to the utility model discloses air conditioning equipment 100, both ends department through in through-flow wind channel 210 sets up respectively and keeps off class portion 221, and will keep off class portion 221 and locate the low reaches of throat 210a of through-flow wind channel 210, thereby can make the air-out area of through-flow wind channel 210's middle part position great, the air-out area of both ends department is less, thereby it is big to adapt to the wind speed in the middle of through-flow wind channel 210, the characteristics that the wind speed of both sides is little, the noise problem that the both sides air current is inhomogeneous to cause has been improved.
It should be noted that the specific type of the air conditioning apparatus 100 according to the embodiment of the present invention is not limited. For example, an air conditioner or an air sterilizer, etc., when the air conditioning apparatus 100 is an air conditioner, the air conditioning apparatus 100 may further include a heat exchanger 30, and the heat exchanger 30 may be disposed upstream and/or downstream of the air duct member 20 so that the air conditioner may adjust the temperature of the air. When the air conditioning apparatus 100 is an air sterilizer, the air conditioning apparatus 100 may further include a sterilizing device, which may be disposed upstream and/or downstream of the air channel member 20 so that the air sterilizer may sterilize, disinfect, etc. air.
