Description

Technical Field

[0001] The present disclosure relates to the technical field of air conditioners, and more particularly, to a housing assembly and an air duct machine. Background Art

[0002] With the development of the air conditioner industry, the product performance has been gradually optimized, and the user's requirement for the comfort of the air duct machine has also increased. In the related art, there are some regions in the housing of the air duct machine that generate eddy currents, which results in a relatively large noise when the air duct machine is operating, affecting the user experience. Summary of the Invention

[0003] The purpose of the present disclosure is to provide a housing assembly that is adapted to eliminate the eddy currents generated in the housing, so as to facilitate reducing the noise when the air duct machine is operating and improving the user experience.

[0004] To achieve the above purpose, the present disclosure provides a housing assembly, including a housing and a first flow dividing member. The housing includes a first region and a second region. The first region includes at least two spaced-apart fan installation areas, and the second region includes a first flow disturbance area disposed between two adjacent fan installation areas. The first flow disturbance area is provided with the first flow dividing member, and the first flow dividing member is configured to eliminate the eddy currents in the first flow disturbance area.

[0005] Through the above technical solution, in the housing assembly provided by the present disclosure, since two adjacent fan installation areas are spaced apart, when the fan of the air duct machine is installed in the fan installation area, the area between two adjacent fan installation areas in the first region can be used as an air inlet area, so that the fan can blow air flow to the second region. Among them, by providing the first flow dividing member in the first flow disturbance area, the first flow dividing member can direct the air flow outside the first flow disturbance area to the first flow disturbance area, that is, the first flow dividing member can eliminate the eddy currents in the first flow disturbance area. Thus, the housing assembly of the present disclosure is adapted to eliminate the eddy currents generated in the housing, so as to facilitate reducing the noise when the air duct machine is operating and improving the user experience.

[0006] In some possible implementation manners, an air outlet is provided between the fan installation area and the second region, and the first flow dividing member is used to guide the air flow flowing out of the air outlet to partially flow to the first flow disturbance area. Thus, the first flow dividing member can direct part of the air flow blown out of the air outlet to the first flow disturbance area, thereby reducing or even avoiding the generation of eddy currents in the first flow disturbance area, and thus eliminating the noise generated by the eddy currents.

[0007] In some possible embodiments, the air outlet is configured to blow air forward. The first flow dividing member extends from the first turbulent flow region to the front side of the air outlet. In the front-rear direction, a projected portion of the first flow dividing member partially falls into the air outlet. Thereby, the amount of air guided by the first flow dividing member to the first turbulent flow region can be increased, so as to be suitable for further reducing the noise during the operation of the air duct machine.

[0008] In some possible embodiments, a flow guiding surface is provided on a side of the first flow dividing member facing the air outlet. The flow guiding surface is configured to guide the air flowing through itself to the first turbulent flow region. Thereby, the flow guiding function of the first flow dividing member can be realized by using the flow guiding surface.

[0009] In some possible embodiments, at least a part of the flow guiding surface is configured as an arc surface protruding forward. Thereby, the flow guiding effect of the flow guiding surface can be improved.

[0010] In some possible embodiments, the first flow dividing member is configured as an arc-shaped plate protruding forward, and the foremost end of the arc-shaped plate is located outside the air outlet. Thereby, it is beneficial to the formation of the above-mentioned arc-shaped flow guiding surface, and more air can flow to the first turbulent flow region under the guiding action of the flow guiding surface.

[0011] In some possible embodiments, at least one through hole is formed in the first flow dividing member, and the through hole penetrates the first flow dividing member along the air outlet direction of the air outlet. Thereby, it is possible to take into account ensuring that the amount of air blown to the evaporator is not too low and eliminating the eddy current in the first turbulent flow region.

[0012] In some possible embodiments, the first flow dividing member is configured as an arc-shaped plate protruding forward, the number of the through holes is multiple, and the through holes extend along the radial direction of the first flow dividing member. Thereby, the diffusion of the air flow in the circumferential direction of the first flow dividing member can be realized, and thereby, it is beneficial to make the air flow fully contact with the evaporator.

[0013] In some possible embodiments, the first flow dividing member is configured as a plate shape, and the through hole extends along the thickness direction of the first flow dividing member. Wherein, the projected area of the first flow dividing member in its own thickness direction is the first area, and the projected area of at least one through hole in the thickness direction is the second area. The ratio of the second area to the first area is less than or equal to 0.85. Thereby, it is possible to avoid the ratio being too large, resulting in too little air flow flowing into the first turbulent flow region and affecting the noise reduction effect.

[0014] In some possible embodiments, the ratio of the second area to the first area is 0.25 to 0.65. Thereby, it is possible to avoid the ratio being too small and affecting the air output of the air duct machine, and avoid the ratio being too large and affecting the noise reduction effect.

[0015] In some possible embodiments, the through hole is configured as an oblong hole and has a length in the up and down direction. Thereby, a stable air flow pattern can be formed in the through hole, reducing the generation of turbulence and eddy currents, and making the air flow more uniform.

[0016] In some possible embodiments, at least two of the blower installation areas are spaced apart in the left and right direction, and the first flow splitting members are respectively arranged on both sides of the first flow disturbance area in the left and right direction, and the adjacent two first flow splitting members between adjacent two blower installation areas are spaced apart. Thereby, the layout space of the two first flow splitting members can be reduced, and the air flow can flow into or out of the first flow disturbance area between the two first flow splitting members, which is beneficial to improving the noise reduction effect.

[0017] In some possible embodiments, the first flow splitting member includes a first flow splitting section. In the air outlet direction of the air outlet, the projection of the first flow splitting section falls into the air outlet. The first flow splitting member has a width in the left and right direction, and the ratio of the width of the first flow splitting section to the width of the first flow splitting member is 0.05 to 0.85. Thereby, the air volume blown to the first flow splitting section and the flow guiding effect of the first flow splitting member can be taken into account.

[0018] In some possible embodiments, the ratio of the width of the first flow splitting section to the width of the first flow splitting member is 0.35 to 0.65. Thereby, the air volume blown to the first flow splitting section and the flow guiding effect of the first flow splitting member can be taken into account.

[0019] In some possible embodiments, the first flow splitting member includes a second flow splitting section. The second flow splitting section is located outside the air outlet, and the width of the first flow splitting section is smaller than the width of the second flow splitting section. Thereby, the width of the second flow splitting section is larger, which can ensure its own flow guiding effect.

[0020] In some possible embodiments, the air outlet has a width in the left and right direction, and the width of the first flow splitting section is less than half of the width of the air outlet. Thereby, it can be avoided that the first flow splitting member excessively affects the air volume output by the blower and the air volume output by the air duct machine.

[0021] In some possible embodiments, the housing assembly includes a second flow splitting member. The second area includes a second flow disturbance area located outside the outermost blower installation area. The second flow splitting member is arranged in the second flow disturbance area and is used to guide the air flow flowing out of the outermost air outlet to partially flow to the second flow disturbance area. Thereby, the generation of eddy currents in the second flow disturbance area can be reduced or even avoided, thereby eliminating the noise generated by the eddy currents, so as to be suitable for further reducing the noise during the operation of the air duct machine.

[0022] In some possible embodiments, the housing includes a top cover, the air duct machine includes a connecting bracket, and the first flow dividing member is connected to the top cover through the connecting bracket. Thus, the installation and fixation of the first flow dividing member and the housing can be achieved.

[0023] In some possible embodiments, the first flow dividing member and the connecting bracket are integrally formed. Thus, the number of components of the air duct machine can be reduced, and the assembly of the air duct machine can be simplified.

[0024] According to a second aspect of the present disclosure, there is provided an air duct machine, including a fan and the housing assembly as described above. The fan is disposed in the fan installation area and has an air outlet, and the air outlet communicates with a second area. Thus, the fan can blow air flow into the second area through the air outlet.

[0025] In some possible embodiments, the fan is configured as a centrifugal fan.

[0026] In some possible embodiments, at least two fans are arranged at intervals in the left-right direction, and air inlet areas are provided at both the left and right ends of the fan in the first area. Thus, the air inlet of the fan can be ensured.

[0027] In some possible embodiments, the air duct machine includes an evaporator, the evaporator is disposed on the front side of the air outlet, and the first flow dividing member is spaced apart from the evaporator. Thus, a safety gap can be provided between the evaporator and the first flow dividing member, which is beneficial to their normal operation.

[0028] In some possible embodiments, the spacing between the first flow dividing member and the evaporator in the up-down direction is greater than or equal to 10 mm to 14 mm. Thus, it can be avoided that the spacing between the first flow dividing member and the evaporator is too small.

[0029] Other features and advantages of the present disclosure will be described in detail in the following specific implementation section. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0032] The following will describe the detailed implementation manners of the present disclosure with reference to the accompanying drawings. It should be understood that the specific implementation manners described herein are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure.

[0033] In the present disclosure, unless otherwise stated, the orientation terms such as "upper, lower, front, rear, left, right" are based on Figures 1 to 9 defined, and specifically can refer to Figures 1 to 9 the upper, lower, front, rear, left, right therein. The up - down direction can also refer to the gravity direction of the housing assembly and the air duct machine, where the upper corresponds to the top and the lower corresponds to the bottom. "Inner, outer" refers to the inside and outside of the self - contour of each component. The terms "first, second" are used to distinguish one element from another, and do not have sequence and importance. In addition, when the following description involves the accompanying drawings, the same reference numerals in different drawings represent the same or similar elements, and the present disclosure will not repeat this.

[0034] According to some embodiments of the present disclosure, a housing assembly is provided. Refer to Figures 1 to 9As shown in the figure, the housing assembly includes a housing 1 and a first flow divider 3. The housing 1 includes a first region 11 and a second region 12. The first region 11 includes at least two spaced-apart fan installation areas 111. The second region 12 includes a first turbulence region 121 disposed between two adjacent fan installation areas 111. The first flow divider 3 is disposed in the first turbulence region 121 and is configured to eliminate the eddy current in the first turbulence region 121.

[0035] Through the above technical solution, in the housing assembly provided in the present disclosure, since two adjacent fan installation areas 111 are spaced apart, when the fan 2 of the air duct machine is installed in the fan installation area 111, the area between two adjacent fan installation areas 111 in the first region 11 can be used as an air inlet area 112, so that the fan 2 can blow air flow into the second region 12. Among them, by disposing the first flow divider 3 in the first turbulence region 121, the first flow divider 3 can direct the air flow outside the first turbulence region 121 to the first turbulence region 121, that is, the first flow divider 3 can eliminate the eddy current in the first turbulence region 121. Thus, the housing assembly of the present disclosure is suitable for eliminating the eddy current generated in the housing 1, which is beneficial to reducing the noise during the operation of the air duct machine and improving the user experience.

[0036] In some embodiments of the present disclosure, referring to Figures 1 to 9 As shown in the figure, an air outlet 21 is provided between the fan installation area 111 and the second region 12. The first flow divider 3 is used to guide the air flow flowing out through the air outlet 21 to partially flow into the first turbulence region 121. Thus, the first flow divider 3 can direct the air flow blown out from the air outlet 21 to the first turbulence region 121 partially. Thereby, the generation of eddy current in the first turbulence region 121 can be reduced or even avoided, and thus the noise generated by the eddy current can be eliminated.

[0037] It should be noted that the "airflow flowing out through the air outlet 21" can refer to the airflow directly blown out by the air outlet 21, or the airflow blown out through the air outlet 21 into the housing 1. The present disclosure does not limit this. Additionally, since the first turbulence zone 121 is provided between two adjacent fan installation zones 111, the first flow divider 3 of the present disclosure can guide the airflow blown out from any one of the two adjacent air outlets 21 to the first turbulence zone 121. That is, two first flow dividers 3 can be provided in the first turbulence zone 121, and each first flow divider 3 is used to guide the airflow blown out from the corresponding air outlet 21 to the first turbulence zone 121. Alternatively, only one first flow divider 3 can be provided in the first turbulence zone 121, and this first flow divider 3 is used to guide the airflow blown out from both of the two adjacent air outlets 21 to the first turbulence zone 121. Or, only one first flow divider 3 can be provided in the first turbulence zone 121, and this first flow divider 3 is used to guide the airflow blown out from one of the two adjacent air outlets 21 to the first turbulence zone 121, and the step of guiding the airflow blown out from the other air outlet 21 to the first turbulence zone 121 can be omitted.

[0038] It should also be noted that the present disclosure can eliminate the noise generated by the first turbulence zone 121 by adding the first flow divider 3. In this way, the steps of changing the volute structure of the fan 2 in the air duct machine can be omitted, and the steps of changing the shape and size of the fan 2 can also be omitted. Thus, it can be ensured that the overall air intake volume of the air duct machine is not affected. Without changing the distance between two adjacent fans 2, the situation of air robbing between two adjacent fans 2 can be avoided. Therefore, it is suitable for improving the reliability of the air duct machine.

[0039] In some embodiments of the present disclosure, referring to Figures 1 to 3 and Figure 9 as shown in, the housing 1 can include a partition 14. The partition 14 can divide the housing 1 into a first region 11 and a second region 12. The air duct machine can include an evaporator 5, and the evaporator 5 can be arranged in the second region 12. The fan 2 can be arranged in the fan installation zone 111 of the first region 11, and the air outlet 21 of the fan 2 can blow air into the second region 12.

[0040] In some embodiments of the present disclosure, referring to Figures 2 to 5As shown, the air outlet 21 is used for blowing air forward. The first flow dividing member 3 can extend from the first turbulent flow area 121 to the front side of the air outlet 21. In the air blowing direction of the air outlet 21, the projected part of the first flow dividing member 3 partially falls into the air outlet 21. Here, the air blowing direction of the air outlet 21 is the direction from back to front. By extending the first flow dividing member 3 to the front side of the air outlet 21 and making the projected part of the first flow dividing member 3 partially fall into the air outlet 21, the air flow directly blown out through the air outlet 21 can blow towards the part where the first flow dividing member 3 coincides with the projection of the air outlet 21. Since the air flow directly blown out through the air outlet 21 has a higher wind speed and a larger air volume, this setting can improve the air volume of the first flow dividing member 3 guiding the first turbulent flow area 121, thereby being suitable for further reducing the noise during the operation of the air duct machine.

[0041] It should be noted that the first flow dividing member 3 extending to the front side of the air outlet 21 can be understood as one end of the first flow dividing member 3 being relatively close to the air outlet 21, and the distance between the two is set to be small or zero. In some embodiments, the first flow dividing member 3 is relatively closer to the air outlet 21 than the evaporator 5, so that the first flow dividing member 3 can extend to the front side of the air outlet 21. Of course, the first flow dividing member 3 can also extend from the first turbulent flow area 121 to the air outlet 21, that is, the interval between one end of the first flow dividing member 3 and the air outlet 21 is zero. In other embodiments, the first flow dividing member 3 can also extend into the blower 2, and the present disclosure does not limit this.

[0042] In some embodiments of the present disclosure, referring to Figures 3 to 5 As shown, a guiding surface 31 can be provided on the side of the first flow dividing member 3 facing the air outlet 21. The guiding surface 31 is used to guide the air flow flowing through itself towards the first turbulent flow area 121. In this way, the air flow blown out through the air outlet 21 can blow towards the guiding surface 31, and then can be blown towards the first turbulent flow area 121 under the guidance of the guiding surface 31, realizing the guiding function of the first flow dividing member 3.

[0043] Of course, in other embodiments, the first flow dividing member 3 can also include a guiding channel. One end of the guiding channel faces the air outlet 21, and the other end faces the first turbulent flow area 121. In this way, the air flow blown out through the air outlet 21 can blow into the guiding channel and then flow towards the first turbulent flow area 121. Thus, the guiding function of the first flow dividing member 3 can also be realized.

[0044] In some embodiments, referring to Figures 3 to 5 As shown, at least part of the guiding surface 31 can be configured as an arc surface protruding forward. In this way, referring to Figure 5As shown in the figure, the air flow can blow towards the part of the first flow splitter 3 that coincides with the projection of the air outlet 21. Subsequently, after this part of the air flow contacts the guide surface 31, it can be deflected and reflected under the action of the guide surface 31, and then further flow to the first turbulent flow area 121. Thus, the guiding effect of the guide surface 31 can be improved.

[0045] Of course, in some other embodiments, referring to Figure 7 As shown in the figure, the first flow splitter 3 may include two plate segments arranged at an angle. The plate segment close to the air outlet 21 is arranged at an angle with the air outlet 21. That is to say, the projection of the guide surface 31 in the up and down direction can be constructed as a cone. In this way, the air flow can blow towards the part of the first flow splitter 3 that coincides with the projection of the air outlet 21. Subsequently, after this part of the air flow contacts the guide surface 31, it can be deflected and reflected under the action of the conical guide surface 31, and then further flow to the first turbulent flow area 121. Thus, the guiding effect of the guide surface 31 can also be improved. In addition, the first flow splitter 3 may include at least one arc-shaped plate segment and / or at least one straight plate segment, and the present disclosure does not limit this.

[0046] In some embodiments, referring to Figures 3 to 5 As shown in the figure, in the embodiment where the guide surface 31 is constructed as an arc surface, the first flow splitter 3 can be constructed as an arc-shaped plate protruding forward, and the front end of the arc-shaped plate can be located outside the air outlet 21. In this way, on the one hand, the setting of the arc-shaped plate is beneficial to the formation of the above-mentioned arc-shaped guide surface 31. On the other hand, arranging the front end of the arc-shaped plate outside the air outlet 21 can make more air flow to the first turbulent flow area 121 under the guiding action of the guide surface 31.

[0047] In some embodiments of the present disclosure, referring to Figure 2 、 Figure 4 and Figure 5 As shown in the figure, at least one through hole 32 can be opened on the first flow splitter 3, and the through hole 32 can penetrate the first flow splitter 3 along the air outlet direction of the air outlet 21. Here, when the projected part of the first flow splitter 3 partially falls into the air outlet 21, such a setting will cause a part of the air flow to flow towards the first flow splitter 3, reducing the air output of the blower 2. The present disclosure opens the through hole 32 on the first flow splitter 3, so that part of the air flow blowing towards the first flow splitter 3 can flow out of the first flow splitter 3 through the through hole 32 and continue to flow forward to blow towards the evaporator 5 located in front of the blower 2. Thus, the above setting can take into account ensuring that the air volume blowing towards the evaporator 5 is not too low and eliminating the eddy current in the first turbulent flow area 121. In some embodiments, the number of through holes 32 is multiple, and the multiple through holes 32 can be arranged in rows and columns, and the present disclosure does not limit this.

[0048] In some embodiments of the present disclosure, referring to Figures 3 to 5As shown, the first flow divider 3 can be configured as an arc-shaped plate protruding forward. The number of through holes 32 is multiple, and the through holes 32 can extend radially along the first flow divider 3. In this way, the multiple through holes 32 can also achieve the diffusion of the airflow along the circumference of the first flow divider 3. Thus, it is beneficial to make the airflow fully contact the evaporator 5. In some embodiments, when the number of through holes 32 is multiple, the multiple through holes 32 can include two through holes 32 with different cross-sectional areas, and the present disclosure does not limit this.

[0049] In some embodiments, referring to Figures 2 to 5 As shown, the first flow divider 3 is configured as a plate, and the through holes 32 can extend along the thickness direction of the first flow divider 3. Wherein, the projected area of the first flow divider 3 along its own thickness direction is the first area, and the projected area of at least one through hole 32 along the thickness direction is the second area. The ratio of the second area to the first area is less than or equal to 0.85, for example, less than or equal to 0.8. In this way, it is possible to avoid the ratio being too large, resulting in too little airflow flowing into the first turbulent flow area 121 and affecting the noise reduction effect. Here, when the number of through holes 32 is multiple, the second area is the sum of the projected areas of the multiple through holes 32.

[0050] In some embodiments, the ratio of the second area to the first area can be 0.25 - 0.65, for example, it can be 0.3 - 0.6. In this way, it is possible to avoid the ratio being too small and affecting the air volume output of the air duct machine, and to avoid the ratio being too large and affecting the noise reduction effect.

[0051] In some embodiments, referring to Figure 2 and Figure 9 As shown, the through holes 32 can be configured as oblong holes, and the through holes 32 have a length in the up and down direction. In this way, the through holes 32 can form a stable airflow pattern, reduce the generation of turbulence and eddy currents, and make the air flow more uniform. Of course, in other embodiments, the through holes 32 can also be configured as round holes, rectangular holes, polygonal holes, and special-shaped holes, and the present disclosure does not limit this.

[0052] In some embodiments of the present disclosure, referring to Figures 2 to 5 As shown, at least two fan installation areas 111 are spaced apart in the left and right directions. First flow dividers 3 can be respectively arranged on both sides of the first turbulent flow area 121 in the left and right directions, and the adjacent two first flow dividers 3 between adjacent two fan installation areas 111 are spaced apart. Wherein, each first flow divider 3 is used to direct the airflow blown out from the air outlet 21 on the same side to the first turbulent flow area 121. Spacing the adjacent two first flow dividers 3 apart, on the one hand, can reduce the layout space of the two first flow dividers 3, and on the other hand, can make the airflow flow into or out of the first turbulent flow area 121 between the two first flow dividers 3, which is beneficial to improving the noise reduction effect.

[0053] Of course, in some other embodiments of the present disclosure, referring toFigure 6 As shown, two adjacent first flow splitters 3 can be connected together, so that the assembly of the housing assembly and the air duct machine can be simplified, and the reliability of the housing assembly and the air duct machine can be improved.

[0054] In some embodiments of the present disclosure, referring to Figure 4 As shown, the first flow splitter 3 may include a first flow splitting section 33. In the air outlet direction of the air outlet 21, the projection of the first flow splitting section 33 falls into the air outlet 21. The first flow splitter 3 has a width in the left-right direction. The ratio of the width of the first flow splitting section 33 to the width of the first flow splitter 3 may be 0.05 to 0.85, for example, it may be 0.1 to 0.8. In this way, the air volume blown to the first flow splitting section 33 and the flow guiding effect of the first flow splitter 3 can be taken into account. Among them, referring to Figure 4 As shown, the width of the first flow splitting section 33 may be L1, and the width of the first flow splitter 3 may be L2.

[0055] In some embodiments, the ratio of the width of the first flow splitting section 33 to the width of the first flow splitter 3 may be 0.35 to 0.65, for example, it may be 0.3 to 0.6. In this way, the air volume blown to the first flow splitting section 33 and the flow guiding effect of the first flow splitter 3 can be taken into account.

[0056] In some embodiments, referring to Figure 4 As shown, the first flow splitter 3 may include a second flow splitting section 34. The second flow splitting section 34 is located outside the air outlet 21. The second flow splitting section 34 may be arranged in the first turbulent flow area 121. The width of the first flow splitting section 33 may be smaller than the width of the second flow splitting section 34. In this way, the width of the second flow splitting section 34 is larger, which can ensure its own flow guiding effect. Among them, the width of the second flow splitting section 34 may be the width of the first flow splitter 3 minus the width of the first flow splitting section 33, and the present disclosure does not limit this.

[0057] In some embodiments, referring to Figure 4 As shown, the air outlet 21 has a width in the left-right direction. The width of the first flow splitting section 33 is less than half of the width of the air outlet 21. In this way, it can be avoided that the first flow splitter 3 excessively affects the air volume output by the blower 2 and the air volume output of the air duct machine.

[0058] In some embodiments of the present disclosure, referring to Figure 8As shown, the housing assembly may include a second flow diverter 4. The housing 1 includes a second turbulent flow area 122 outside the outermost fan installation area 111. The second flow diverter 4 is disposed in the second turbulent flow area 122 and is used to guide the air flow flowing out through the outermost air outlet 21 to partially flow into the second turbulent flow area 122. Here, when the air duct machine includes two fans 2, each fan 2 is the outermost fan 2. By providing the second flow diverter 4, the air flow blown out from the air outlet 21 can be partially guided to the second turbulent flow area 122. Thus, the eddy current in the second turbulent flow area 122 can be eliminated, and the generation of eddy current in the second turbulent flow area 122 can be reduced or even avoided, thereby eliminating the noise generated by the eddy current to be suitable for further reducing the noise during the operation of the air duct machine.

[0059] It should be noted that the first turbulent flow area 121 and the second turbulent flow area 122 can be understood as areas where the internal air flow basically does not flow.

[0060] In some embodiments, the second flow diverter 4 and the first flow diverter 3 may be made of the same structure. That is to say, the second flow diverter 4 may also have the above-mentioned first flow diversion section 33 and second flow diversion section 34, may also be provided with through holes 32, and may also be configured as an arc-shaped plate and have an arc-shaped guiding surface 31. That is, the second flow diverter 4 and the first flow diverter 3 are the same structural unit.

[0061] In some embodiments of the present disclosure, referring to Figure 2 and Figure 9 As shown, the housing 1 may include a top cover 13. The air duct machine may include a connecting bracket 6. The first flow diverter 3 may be connected to the top cover 13 through the connecting bracket 6. In this way, the installation and fixation of the first flow diverter 3 and the housing 1 can be realized. Of course, the second flow diverter 4 may also be connected to the top cover 13 through the connecting bracket 6.

[0062] In some embodiments, the first flow diverter 3 may be integrally formed with the connecting bracket 6. In this way, the number of components of the air duct machine can be reduced, and the assembly of the air duct machine can be simplified. Of course, the second flow diverter 4 may also be integrally formed with the corresponding connecting bracket 6.

[0063] According to the second aspect of the present disclosure, there is provided an air duct machine, including a fan 2 and the housing assembly as described above. The fan 2 is disposed in the fan installation area 111 and has an air outlet 21. The air outlet 21 communicates with the second area 12. Thus, the fan 2 can blow the air flow into the second area 12 through the air outlet 21. This air duct machine has all the beneficial effects of the above-mentioned housing assembly, and the present disclosure will not elaborate herein.

[0064] In some embodiments of the present disclosure, the fan 2 may be a centrifugal fan.

[0065] In some embodiments, referring to Figure 5As shown in the figure, at least two fans 2 are arranged at intervals in the left - right direction, and air inlet areas 112 are provided at both the left and right ends of the fans 2 in the first area 11. Thus, the air inlet of the fans 2 can be ensured.

[0066] In some embodiments of the present disclosure, referring to Figure 9 As shown in the figure, the air duct machine may include an evaporator 5. The evaporator 5 is arranged on the front side of the air outlet 21, and the first flow - dividing member 3 may be arranged at an interval from the evaporator 5. Thus, a safety gap can be formed between the evaporator 5 and the first flow - dividing member 3, which is beneficial to their normal operation. Of course, the above - mentioned second flow - dividing member 4 may also be arranged at an interval from the evaporator 5.

[0067] In some embodiments, referring to Figure 9 As shown in the figure, the interval between the first flow - dividing member 3 and the evaporator 5 in the up - down direction is greater than or equal to 10 mm - 14 mm, for example, greater than or equal to 12 mm. In this way, the interval between the first flow - dividing member 3 and the evaporator 5 can be prevented from being too small. Among them, referring to Figure 9 As shown in the figure, the interval between the first flow - dividing member 3 and the evaporator 5 in the up - down direction can be L3, that is, L3 can be greater than or equal to 10 mm - 14 mm.

[0068] In some embodiments, referring to Figures 3 to 7 As shown in the figure, the fan 2 may include a diffuser section 22, and the diffuser section 22 may have an air outlet 21. Among them, the air outlet 21 may be arranged in the second area 12, and the present disclosure does not limit this.

[0069] Next, the present disclosure will introduce the working process and noise reduction process of the air duct machine in detail in combination with the above - mentioned specific embodiments. Referring to Figure 8 As shown in the figure, when the fan 2 starts, the air flow generated by the fan 2 flows out through the air outlet 21 of the diffuser section 22. Among them, most of the air flow directly flows forward to the evaporator 5, and a small part of the air flow flows to the first flow - dividing member 3. At this time, a part of the air flow flowing to the first flow - dividing member 3 flows out through the through - hole 32 and flows forward to the evaporator 5, and another part of the air flow flowing to the first flow - dividing member 3 flows to the first turbulent flow area 121 after being guided by the guiding surface 31, thereby eliminating most of the eddy currents in the first turbulent flow area 121 and reducing the low - frequency noise generated in the first turbulent flow area 121.

[0070] In addition, when the air duct machine includes the second flow - dividing member 4, a part of the air flow flowing to the second flow - dividing member 4 flows out through the through - hole 32 on the second flow - dividing member 4 and flows forward to the evaporator 5, and another part of the air flow flowing to the second flow - dividing member 4 flows to the second turbulent flow area 122 after being guided by the guiding surface 31 of the second flow - dividing member 4, thereby eliminating most of the eddy currents in the second turbulent flow area 122 and reducing the low - frequency noise generated in the second turbulent flow area 122.

[0071] The preferred embodiments of the present disclosure have been described in detail above in conjunction with the accompanying drawings. However, the present disclosure is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0072] In addition, it should be noted that, in the various specific technical features described in the above specific embodiments, they can be combined in any suitable manner without conflict. To avoid unnecessary repetition, the present disclosure will not separately describe various possible combination manners.

[0073] Furthermore, any combination can be made between various different embodiments of the present disclosure as long as it does not violate the idea of the present disclosure, and it should also be regarded as the content disclosed by the present disclosure.
