The embodiments described herein are only used to more clearly illustrate the technical solutions of the present application, so they are only examples and cannot be used to limit the protection scope of the present application.

[0035] In the description of the present application, the terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more features.

[0036] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application.

[0037] The embodiments of the present application provide a wind valve, a fresh air module and an air conditioner to solve the problem of large wind resistance of the fresh air module. The following will be described with reference to the accompanying drawings.

[0038] The embodiments of the present application provide a wind valve 1, which includes a valve plate for controlling the opening and closing of the air outlet and a rectifying plate 4 for rectifying when the air outlet is opened. A plurality of rectifying holes 41 are formed in the rectifying plate 4.

[0039] The wind valve 1 provided by the embodiments of the present application blocks the air outlet by setting the valve plate to control the opening and closing of the air outlet. By setting the rectifying plate 4, the air flow passing through the wind valve can be discharged through the rectifying holes 41 under the guidance of the rectifying plate 4, solving the problem of large wind resistance of the fresh air module.

[0040] In this embodiment, the first direction is the opening direction of the air inlet 12, the second direction is the thickness direction of the rectifying plate, and the first direction is perpendicular to the second direction.

[0041] Please refer to Figure 1 , the wind valve 1 includes a first valve plate 2, a second valve plate 3, a connecting portion 5 and a rectifying plate 4. The first valve plate 2, the second valve plate 3 and the connecting portion 5 are integrally formed with the rectifying plate 4. The first valve plate 2 and the second valve plate 3 are both perpendicular to the rectifying plate 4, and the first valve plate 2 and the second valve plate 3 are respectively located at two adjacent ends of the rectifying plate 4. The ends of the first valve plate 2 and the second valve plate 3 facing away from the first direction are close to each other, and the ends of the first valve plate 2 and the second valve plate 3 in the first direction are away from each other to form an air inlet 12. In this embodiment, the length of the first valve plate 2 is less than the length of the second valve plate 3.

[0042] Please refer to Figure 1The connecting part 5 includes a connecting plate 51, a connecting rod 52 and a connecting block 53. The connecting plate 51 is located at one end of the rectifying plate 4 away from the first direction. The connecting plate 51 connects the first valve plate 2 and the second valve plate 3. The connecting block 53 is located at one end of the connecting plate 51 away from the first direction. The connecting rod 52 is connected to the connecting block 53 and the connecting plate 51. The connecting block 53 is provided with a connecting hole 531 for connecting with an external driving device, so that the external driving device can drive the air valve 1 to rotate with the core axis of the connecting hole 531 as the rotation center. In this embodiment, an avoidance gap 42 is provided on the rectifying plate 4 to facilitate the external driving device to drive the air valve 1 to block different air outlets.

[0043] See also Figure 1 , a plurality of rectifying holes 41 are provided on the rectifying plate 4, and the plurality of rectifying holes 41 all penetrate the rectifying plate 4 along the second direction. The rectifying holes 41 are provided to rectify and guide the pre-swirl airflow in the fresh air module 6, improve the flow organization, and reduce the turbulent loss. Moreover, the airflow passing through the plurality of rectifying holes 41 will generate an airflow jet phenomenon, converting a small-flow high-speed airflow into a large-flow low-speed airflow. The generated airflow induced effect obtains a large amount of flow, thereby increasing the system air volume, that is, reducing the wind resistance.

[0044] See also Figure 1 In this embodiment, the rectifying hole 41 is a circular hole, the diameter of the rectifying hole 41 is D, the hole spacing is S, the porosity is β, 2mm≤D≤3mm, 4mm≤S≤5mm, 40%≤β≤60%. When D<2mm, the aperture of the rectifying hole 41 is smaller, resulting in a smaller air flow volume of the rectifying hole 41, which makes the wind resistance larger; when D>3mm, the aperture of the rectifying hole 41 is larger, resulting in a worse air flow injection effect, resulting in a reduced air flow volume. When S<4mm or β>60%, the structural strength of the air valve 1 is poor, and when S>5mm or β<40%, the number of the rectifying holes 41 is small, resulting in a reduced total air flow volume. By making 2mm≤D≤3mm, 4mm≤S≤5mm, and 40%≤β≤60%, the structural strength of the air valve 1 can be ensured while increasing the air flow volume of the rectifying hole 41.

[0045] See also Figure 2 In some embodiments of the present application, the rectifying hole 41 is a rectangular hole, the length of the rectifying hole 41 is A, the width of the rectifying hole 41 is B, the hole spacing is C, 4mm≤A≤6mm, 4mm≤B≤6mm, 1.2mm≤C≤1.5mm. By making 4mm≤A≤6mm, 4mm≤B≤6mm, 1.2mm≤C≤1.5mm, the structural strength of the air valve 1 can be ensured while increasing the air flow of the rectifying hole 41.

[0046] See also Figure 3, in some embodiments of the present application, the rectifying holes 41 are oblong holes. The major axis length of the rectifying hole 41 is E, the minor axis length of the rectifying hole 41 is F, and the hole pitch of the rectifying hole 41 is G, where 6 mm ≤ E ≤ 8 mm, 3 mm ≤ F ≤ 3.5 mm, and 1.5 mm ≤ G ≤ 2 mm. By setting 6 mm ≤ E ≤ 8 mm, 3 mm ≤ F ≤ 3.5 mm, and 1.5 mm ≤ G ≤ 2 mm, it is possible to ensure the structural strength of the air valve 1 while increasing the air guiding amount of the rectifying holes 41.

[0047] Please refer to Figure 4 , in some embodiments of the present application, the rectifying holes 41 are arc-shaped long holes. The rectifying holes 41 extend from the first valve plate 2 to the second valve plate 3. A plurality of rectifying holes 41 are sequentially arranged at intervals from the inside to the outside with the core axis of the connecting hole 531 as the center, and the distance between two adjacent rectifying holes 41 from the inside to the outside gradually increases. When the air flow in the fresh air module 6 passes through the arc-shaped long holes, the vortex core will be rectified into multiple arc-shaped airflows, which can reduce the pressure pulsation at the core and achieve the effect of noise reduction and efficiency improvement.

[0048] Please refer to Figure 5 and Figure 6 , the embodiments of the present application further provide a fresh air module 6. The fresh air module 6 includes the air valve 1 as described above, as well as a housing 61, a sound-absorbing cotton 62, a sound-damping sheet 63, a filter rack 64, a fan 65, and a volute 66. The housing 61 and the volute 66 enclose a fresh air cavity. The air valve 1, the sound-absorbing cotton 62, the sound-damping sheet 63, the filter rack 64, and the fan 65 are all arranged in the fresh air cavity. The housing 61 is provided with an internal circulation air inlet and a fresh air inlet 67. The air valve 1 is fixedly connected to the output shaft of the motor 69, and the motor 69 is fixedly connected to the housing 61. The motor 69 is used to drive the air valve 1 to block the internal circulation air inlet or the fresh air inlet 67. The sound-absorbing cotton 62 and the sound-damping sheet 63 are both fixedly connected to the filter rack 64, and the fan 65 is arranged on one side of the filter rack 64 close to the volute 66.

[0049] Since the fan 65 is an axial flow fan 65, and the opening directions of the internal circulation air inlet and the fresh air inlet 67 are both perpendicular to the exhaust direction of the fan 65, by setting the air valve 1, when blocking the internal circulation air inlet or the fresh air inlet 67, the air flow direction flowing through the air valve 1 can be changed from the first direction to the second direction, realizing the guidance of the gas flowing through the air valve 1 and solving the problem of large air resistance of the fresh air module 6.

[0050] The embodiments of the present application further provide an air conditioner. The air conditioner includes the fresh air module 6 as described above. Since this air conditioner has the above-mentioned fresh air module 6, it has at least some or all of the beneficial effects of the above-mentioned fresh air module 6, which will not be elaborated here one by one.

[0051] In the above embodiments, the descriptions of the respective embodiments have their own focuses. For parts not detailed in a certain embodiment, reference may be made to the relevant descriptions of other embodiments.

[0052] Finally, it should be noted that although the above embodiments have been described in the text of the specification and the drawings of the present application, the patent protection scope of the present application cannot be limited thereby. Any technical solution obtained by equivalent structure or equivalent process substitution or modification based on the substantial concept of the present application and using the content recorded in the text of the specification and the drawings of the present application, as well as the direct or indirect implementation of the technical solutions of the above embodiments in other related technical fields, etc., are all included in the patent protection scope of the present application.
