For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0065] The air duct component 10 according to an embodiment of the present invention will be described below with reference to the drawings.

[0066] AsFigure 6 As shown, the air duct component 10 according to an embodiment of the present invention includes a front cover plate 1, a rear cover plate assembly 2, a first air wheel 3, and a second air wheel 4.

[0067] Specifically, referring to the attached Figure 4 As shown, the front cover plate 1 has a first air outlet 11 and a second air outlet 12 that are spaced apart. The air flow within the air duct component 10 can be discharged from the first air outlet 11 and the second air outlet 12. The rear cover plate assembly 2 is connected to the front cover plate 1 and is located between the first air outlet 11 and the second air outlet 12, and can divide the air duct formed by the air duct component 10 into two spaces, which is beneficial to the diversion of the air flow. The first air wheel 3 and the second air wheel 4 are provided on one side of the front cover plate 1 facing the rear cover plate assembly 2 and are respectively located on both sides of the rear cover plate assembly 2, and are used to drive the air flow into the interior of the air duct component 10.

[0068] Furthermore, referring to the attached Figure 5 As shown, the rear cover plate assembly 2 has a cavity 210 inside. The side of the rear cover plate assembly 2 facing away from the front cover plate 1 has a plurality of spaced-apart micropores 220, and the micropores 220 communicate with the cavity 210. It can be understood that when the first air wheel 3 and / or the second air wheel 4 rotates, a rotational noise will be generated at the rear cover plate assembly 2, and the generated noise can enter the cavity 210 of the rear cover plate assembly 2 through the plurality of micropores 220, reducing the noise at the rear cover plate assembly 2, reducing the noise at the sound source in the vicinity, thereby being able to improve the user experience and meet the user's usage requirements. Moreover, compared with the prior art method of reducing noise by increasing the diameter of the air wheel or increasing the length of the air wheel, reducing the noise at the rear cover plate assembly 2 by providing the micropores 220 and the cavity 210 can relatively reduce the production cost of the air duct component 10 and reduce the volume of the air duct component 10.

[0069] Preferably, both the first air wheel 3 and the second air wheel 4 are cross-flow air wheels.

[0070] For the air duct component 10 according to an embodiment of the present invention, since the rear cover plate assembly 2 has a cavity 210 inside, the side of the rear cover plate assembly 2 facing away from the front cover plate 1 has a plurality of spaced-apart micropores 220, and the micropores 220 communicate with the cavity 210, the noise generated by the rotation of the first air wheel 3 and the second air wheel 4 can enter the cavity 210 of the rear cover plate assembly 2 through the plurality of micropores 220, and it is possible to reduce the noise at the rear cover plate assembly 2 on the basis of ensuring the volume and production cost of the air duct component 10, achieving the purpose of noise reduction, thereby being able to improve the user experience and meet the user's usage requirements.

[0071] In some embodiments of the present invention, referring to the attached Figure 5 and the attached Figure 7As shown, the rear cover assembly 2 includes a rear cover 21 and a middle partition 22.

The micropores 220 are arranged on the middle partition plate 22. On the basis of playing a noise reduction role, the flatness of the front cover plate 1 and the rear cover plate 21 can be ensured, the wind resistance at the front cover plate 1 and the rear cover plate 21 can be reduced as much as possible, the air flow is avoided from being unsmooth, and the air volume inside the air duct component 10 is ensured.

[0072] In a further embodiment of the present invention, referring to the attached Figure 5 and attached Figure 11 As shown, the middle partition 22 includes a partition plate 221, a first guide plate 222 and a second guide plate 223. The partition plate 221 is located on the side of the rear cover plate 21 away from the front cover plate 1 and along the length direction of the middle partition 22 (see the attached Figure 7 The partition plate 221 extends in the direction perpendicular to the length of the middle partition plate 22 from the rear cover plate assembly 2 to the front cover plate 1.

[0073] Further, see Attachment Figure 5 As shown, one end of the first guide plate 222 and one end of the second guide plate 223 are connected to one end of the partition plate 221 close to the front cover plate 1, and the other end of the first guide plate 222 and the other end of the second guide plate 223 are respectively connected to the two ends of the rear cover plate 21 in the width direction, and a cavity 210 is defined between the first guide plate 222, the second guide plate 223 and the rear cover plate 21, and at least one of the first guide plate 222 and the second guide plate 223 is provided with a microhole 220. The noise generated by the rotation of the first wind wheel 3 and the second wind wheel 4 can enter the cavity 210 defined by the first guide plate 222, the second guide plate 223 and the rear cover plate 21 through the multiple microholes 220 on the first guide plate 222 and / or the second guide plate 223, which can achieve the purpose of noise reduction, improve the user experience, and meet the user's usage needs.

[0074] It should be noted that, only the first guide plate 222 may be provided with micropores 220, and the second guide plate 223 may not have micropores 220; only the second guide plate 223 may be provided with micropores 220, and the first guide plate 222 may not have micropores 220; or both the first guide plate 222 and the second guide plate 223 may be provided with micropores 220.

[0075] In a further embodiment of the present invention, referring to the attached Figure 18 and attached Figure 19 As shown, in the direction from the rear cover plate assembly 2 to the front cover plate 1, the first guide plate 222 and the second guide plate 223 are inclined in a direction away from each other, which can leave a certain space for the setting of the cavity 210, so that the first guide plate 222, the second guide plate 223 and the rear cover plate 21 jointly define the cavity 210.

[0076] In a further embodiment of the present invention, referring to the attached Figure 16 and attached Figure 17 As shown, the first guide plate 222 is provided with micropores 220, and the porosity of the micropores 220 is 20%-40%, so as to ensure the noise reduction effect of the micropores 220 on the rear cover plate assembly 2, improve the user experience, and meet the user's use needs. For example, the porosity of the micropores 220 on the first guide plate 222 can be 20%, 25%, 30%, 35% or 40%.

[0077] and / or, refer to the attached Figure 16 and attached Figure 17 As shown, the second guide plate 223 is provided with micropores 220, and the porosity of the micropores 220 is 20%-40%, so as to ensure the noise reduction effect of the micropores 220 on the rear cover plate assembly 2, improve the user experience, and meet the user's use needs. For example, the porosity of the micropores 220 on the second guide plate 223 can be 20%, 25%, 30%, 35% or 40%.

[0078] In a further embodiment of the present invention, referring to the attached Figure 5 and attached Figure 8 As shown, the rear cover plate 21 includes a third guide plate 211 and a fourth guide plate 212, one end of the third guide plate 211 close to the front cover plate 1 and one end of the fourth guide plate 212 close to the front cover plate 1 are connected and connected to the front cover plate 1, and one end of the third guide plate 211 away from the front cover plate 1 and one end of the fourth guide plate 212 away from the front cover plate 1 are respectively connected to the two ends of the width direction of the middle partition plate 22, in the direction from the front cover plate 1 to the rear cover plate assembly 2, the third guide plate 211 and The distance between the fourth guide plates 212 gradually increases, which can ensure the flatness and smoothness of the connection between the front cover plate 1 and the rear cover plate 21, reduce the wind resistance at the front cover plate 1 and the rear cover plate 21 as much as possible, avoid unsmooth air flow, ensure the air volume inside the air duct component 10, and leave a certain space for the setting of the cavity 210, so that the third guide plate 211, the fourth guide plate 212, the first guide plate 222 and the second guide plate 223 jointly define the cavity 210.

[0079] In a further embodiment of the present invention, referring to the attached Figure 5 and attached Figure 12As shown, at both ends of the middle partition plate 22 in the width direction, there are limiting rib strips 224. The limiting rib strips 224 extend along the length direction of the middle partition plate 22. The surface of the limiting rib strips 224 facing away from the cavity 210 is recessed inward from the surface of the remaining area of the middle partition plate 22 facing away from the cavity 210. The surface of the limiting rib strips 224 far from the cavity 210 abuts against the surface of the rear cover plate 21 facing the cavity 210, which can play a limiting role and prevent the middle partition plate 22 from moving in the width direction of the air duct component 10 (refer to the left-right direction shown in the appendix Figure 5 ), thus causing steps inside the air duct and affecting the smoothness of air flow. Moreover, it can ensure the reliability of the assembly of the middle partition plate 22 and the rear cover plate 21, avoid air leakage from the connection gap between the middle partition plate 22 and the rear cover plate 21, and guarantee the air volume of the air flow.

[0080] In a further embodiment of the present invention, referring to the appendix Figure 5 and the appendix Figure 7 shown, there is a sound-absorbing cotton 5 in the cavity 210. The sound-absorbing cotton 5 extends along the length direction of the rear cover plate assembly 2 (refer to the up-down direction shown in the appendix Figure 7 ), which can absorb the noise entering the cavity 210 from the micropores 220, further improve the noise reduction effect, enhance the user experience, and meet the user's usage requirements. Preferably, the sound-absorbing cotton 5 is made of an anti-corrosion material. Because when the air conditioner 100 is in the refrigeration state, there may be a small amount of condensed water in the air duct component 10, and the anti-corrosion sound-absorbing cotton 5 can prevent the sound-absorbing cotton 5 from getting moldy, thus avoiding the air flow blown out from the first air outlet 11 and the second air outlet 12 from having a musty smell and affecting the user experience.

[0081] In a still further embodiment of the present invention, referring to the appendix Figure 5 and the appendix Figure 7 shown, the sound-absorbing cotton 5 includes a first sound-absorbing cotton 51 and a second sound-absorbing cotton 52. The first sound-absorbing cotton 51 and the second sound-absorbing cotton 52 are arranged in sequence in the direction from the rear cover plate 21 to the middle partition plate 22, which can increase the volume of the sound-absorbing cotton 5 and the space occupied by the sound-absorbing cotton 5 in the cavity 210. The sound waves in the second sound-absorbing cotton 52 can be transmitted to the first sound-absorbing cotton 51, thereby further improving the absorption effect of the sound-absorbing cotton 5 on the noise entering the cavity 210 from the micropores 220 and further improving the noise reduction effect.

[0082] In a yet further embodiment of the present invention, referring to the appendix Figure 9 , the appendix Figure 10 and the appendix Figure 13 shown, in the length direction of the rear cover plate 21 (refer to the appendix Figure 13The first sound-absorbing cotton 51 is clamped between the limiting buckle 213 and the surface of the rear cover plate 21 facing the middle partition plate 22. The limiting buckles 213 are provided at both ends of the length direction of the rear cover plate 21, so that the first sound-absorbing cotton 51 can be adjusted from the length direction of the first sound-absorbing cotton 51 (see the attached figure). Figure 13 The two ends of the upper and lower directions (as shown) play a fixing role for the first sound-absorbing cotton 51, and the first sound-absorbing cotton 51 is fixed between the limit buckle 213 and the surface of the rear cover plate 21 facing the middle partition plate 22, so as to prevent the first sound-absorbing cotton 51 from moving toward the direction close to the middle partition plate 22, thereby improving the reliability and stability of the first sound-absorbing cotton 51.

[0083] In a further embodiment of the present invention, referring to the attached Figure 14 and attached Figure 15 As shown in the attached reference Figure 7 The first sound-absorbing cotton 51 has notches 511 at both ends in the length direction on the side away from the rear cover 21, and the limiting buckles 213 are clamped in the notches 511. Through the cooperation between the limiting buckles 213 and the notches 511, it is possible to ensure the reliability of the fixation of the first sound-absorbing cotton 51 while avoiding the local deformation of the first sound-absorbing cotton 51 caused by the squeezing of the limiting buckles 213, thereby ensuring the reliability of the first sound-absorbing cotton 51 and extending the service life of the first sound-absorbing cotton 51.

[0084] In a further embodiment of the present invention, the first sound-absorbing cotton 51 is adhesively connected to the rear cover 21, which facilitates fixing the first sound-absorbing cotton 51 on the rear cover 21, can improve the reliability of the connection between the first sound-absorbing cotton 51 and the rear cover 21, and further improve the stability and reliability of fixing the first sound-absorbing cotton 51.

[0085] In a further embodiment of the present invention, referring to the attached Figure 5 and attached Figure 19 As shown, both ends of the middle partition 22 in the width direction are connected with a limiting plate 225. In the direction from the middle partition 22 to the rear cover 21, the two limiting plates 225 are inclined in the direction close to each other. The rear cover 21 is connected to the two limiting plates 225. The second sound-absorbing cotton 52 is clamped on the side of the two limiting plates 225 away from the rear cover 21. The two limiting plates 225 can pre-fix the second sound-absorbing cotton 52, prevent the second sound-absorbing cotton 52 from moving in the direction close to the rear cover 21, prevent the second sound-absorbing cotton 52 from falling off, and improve the reliability and stability of the fixing of the second sound-absorbing cotton 52. In addition, in the direction from the middle partition 22 to the rear cover 21, the two limiting plates 225 are inclined in the direction close to each other, which can guide the second sound-absorbing cotton 52 and facilitate the loading of the second sound-absorbing cotton 52.
