[0075] An air handling module 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0076] Referring to Figures 1 - 13 、 Figures 17 - 26 As shown, the air handling module 100 according to an embodiment of the present invention may include: a housing 10, a duct 11 and a blower wheel 20.

[0077] Specifically, the housing 10 has an air inlet 12 and an air outlet 13. The duct 11 is disposed inside the housing 10. The air inlet 12 and the air outlet 13 are connected through the duct 11. The blower wheel 20 is disposed inside the duct 11. The blower wheel 20 can drive the air flow to flow from the air inlet 12 to the air outlet 13. Thus, under the driving action of the blower wheel 20, the air flow can enter the duct 11 through the air inlet 12 and flow out through the air outlet 13, realizing the flow and guiding of the air flow, meeting the required air flow requirements, facilitating the guiding of the air flow, and facilitating the control of the air flow.

[0078] The inventors of the present application have found that in the related art, during the operation of the air handling module, noises and abnormal sounds are generated, and when the air volume and the wind wheel speed of the air handling module are increased, the noise in the air duct will increase, exceeding the noise standard, seriously affecting the user experience and comfort.

[0079] To solve the problem of the air handling module 100 generating relatively large noises and abnormal sounds, in the present invention, as Figure 3 , Figures 5 - 11 , Figures 17 - 26 shown, the air handling module 100 further includes a noise reduction structure 30. The noise reduction structure 30 is provided on the inner wall surface of the air duct 11. The noise reduction structure 30 includes a plurality of (greater than or equal to two) protrusions 31. The plurality of protrusions 31 are spaced apart, realizing the structure of the wall surface of a noise test chamber, making the structure simple and facilitating processing and manufacturing.

[0080] When the noise sound wave in the air duct 11 propagates along the air flow direction in the air duct 11, following the characteristics of the sound wave, when the noise sound wave in the air duct 11 encounters the obstruction of the protrusion 31, it will be reflected between the plurality of protrusions 31 or between the protrusion 31 and the inner wall surface of the air duct 11, effectively reducing the energy of the noise sound wave. And after multiple reflections by the plurality of protrusions 31, it can greatly weaken the energy of the noise sound wave in the air duct 11, thereby reducing the noise value of the air duct 11 and weakening abnormal sounds, and improving the user experience and comfort. For example, the reflection path of the noise sound wave energy can be as Figure 32 shown by the arrow.

[0081] In some embodiments, as Figure 3 , Figures 5 - 11 , Figures 17 - 26 shown, the noise reduction structure 30 can be a plurality of (greater than or equal to two). The plurality of noise reduction structures 30 are all provided on the inner wall surface of the air duct 11. Through the plurality of noise reduction structures 30, the energy of the noise sound wave can be effectively weakened, which is beneficial to reducing the noise value of the air duct 11 and weakening abnormal sounds.

[0082] According to the air handling module 100 of the embodiment of the present invention, the wind wheel 20 is provided in the air duct 11 and is used to drive the air flow from the air suction port 12 to the air supply port 13. The noise reduction structure 30 is provided on the inner wall surface of the air duct 11. The noise reduction structure 30 includes a plurality of spaced-apart protrusions 31, so that the noise sound wave in the air duct 11 can be reflected multiple times between the plurality of protrusions 31 or between the protrusion 31 and the inner wall surface of the air duct 11, effectively reducing the energy of the noise sound wave, being able to greatly weaken the energy of the noise sound wave in the air duct 11, thereby reducing the noise value of the air duct 11 and weakening abnormal sounds, improving the user experience and comfort, and the structure of the noise reduction structure 30 is simple and facilitating processing and manufacturing.

[0083] In some embodiments of the present invention, as Figures 5 - 11 ,Figures 17 - 26 As shown, the noise reduction structure 30 is provided downstream of the wind wheel 20. When the noise sound waves in the air duct 11 propagate along the air flow direction in the air duct 11, the noise reduction structure 30 located downstream of the wind wheel 20 can effectively reduce the transmission of the noise sound waves, reduce the noise value and weaken the abnormal sound, and is beneficial to reducing the production cost.

[0084] According to some embodiments of the present invention, such as Figures 1 - 13 , Figures 17 - 28 As shown, the air duct 11 includes a flow air duct 41 and an air outlet cavity 51. The housing 10 includes a volute 40 and an air outlet duct member 50. The volute 40 has a flow air duct 41, a fan air outlet 42 and a fan air inlet 43. The fan air outlet 42 and the fan air inlet 43 are communicated with the flow air duct 41. The wind wheel 20 is arranged in the flow air duct 41. The air suction port 12 is communicated with the fan air inlet 43. The air outlet duct member 50 has an air outlet cavity 51, an air supply port 13 and a communication port 52. The air supply port 13 and the communication port 52 are communicated with the air outlet cavity 51. The communication port 52 is communicated with the fan air outlet 42.

[0085] Thus, under the driving action of the wind wheel 20, the air flow can enter the flow air duct 41 through the air suction port 12 and the fan air inlet 43 and flow out through the fan air outlet 42, so that the flowing air flow can enter the air outlet cavity 51 through the communication port 52 and flow out through the air supply port 13, which can realize the flow and guidance of the air flow, meet the required air flow demand, facilitate the guidance of the air flow, change the air flow direction in the air duct 11, and facilitate the control of the air flow. For example, the air flow path can be as shown by the arrows in Figure 3 and Figure 19 .

[0086] In addition, as shown in Figure 3 , Figure 5 , Figures 6 - 11 , Figures 17 - 26 At least one of at least part of the inner wall surface of the flow air duct 41 and at least part of the inner wall surface of the air outlet cavity 51 is provided with the noise reduction structure 30, so that through the noise reduction structure 30, the energy of the noise sound waves in the air duct 11 can be greatly weakened, thereby reducing the noise value of the air duct 11 and weakening the abnormal sound, and improving the user experience and comfort.

[0087] It can be understood that "at least one of at least part of the inner wall surface of the flow air duct 41 and at least part of the inner wall surface of the air outlet cavity 51 is provided with the noise reduction structure 30" can mean that at least part of the inner wall surface of the flow air duct 41 is provided with the noise reduction structure 30, or at least part of the inner wall surface of the air outlet cavity 51 is provided with the noise reduction structure 30, or both at least part of the inner wall surface of the flow air duct 41 and at least part of the inner wall surface of the air outlet cavity 51 are provided with the noise reduction structure 30.

[0088] For example, in some embodiments, such asFigure 3 , Figures 5 - 11 As shown in Figures 5 - 11 , at least part of the inner wall surface of the flow air duct 41 is provided with a noise reduction structure 30. When the noise sound wave in the flow air duct 41 propagates along the air flow direction in the flow air duct 41, following the sound wave characteristics, when the noise sound wave in the flow air duct 41 encounters the protrusion 31 and is blocked, it will be reflected between multiple protrusions 31 or between the protrusion 31 and the inner wall surface of the flow air duct 41, effectively reducing the energy of the noise sound wave. And after multiple reflections by multiple protrusions 31, it can greatly weaken the energy of the noise sound wave in the flow air duct 41, thereby reducing the noise value of the flow air duct 41 and weakening abnormal sounds, improving the user experience and comfort. And it can meet the noise standard while facilitating the increase of the air volume of the air handling module 100 and the rotation speed of the wind wheel 20 to meet the required usage requirements.

[0089] In the related art, due to the relatively large volume of the air outlet duct member, cavity reverberation sound is easily generated, and the air outlet duct member will sharply increase or decrease the air outlet area to change the air flow direction, thus easily generating turbulent abnormal sounds. At the same time, when increasing the air volume of the air handling module and the rotation speed of the wind wheel, the noise in the air duct will increase, thus exceeding the noise standard, seriously affecting the user experience and comfort.

[0090] For example, in some embodiments, as Figures 12 - 26 shown, at least part of the inner wall surface of the air outlet cavity 51 is provided with a noise reduction structure 30. When the noise sound waves in the flow air duct 41 and the air outlet cavity 51 propagate along the air flow direction, following the sound wave characteristics, when the noise sound wave in the air outlet cavity 51 encounters the protrusion 31 and is blocked, it will be reflected between multiple protrusions 31 or between the protrusion 31 and the inner wall surface of the air outlet cavity 51, effectively reducing the energy of the noise sound wave. And after multiple reflections by multiple protrusions 31, it can greatly weaken the energy of the noise sound wave in the air outlet cavity 51, thereby reducing the noise value of the air outlet cavity 51 and weakening abnormal sounds, improving the user experience and comfort. And it can meet the noise standard while facilitating the increase of the air volume of the air handling module 100 and the rotation speed of the wind wheel 20 to meet the required usage requirements.

[0091] For example, in some embodiments, as Figure 3 , Figures 5 - 26As shown, at least part of the inner wall surface of the flow air duct 41 and at least part of the inner wall surface of the air outlet cavity 51 are provided with a noise reduction structure 30. When the noise sound waves in the flow air duct 41 and the air outlet cavity 51 propagate along the air flow direction, following the characteristics of sound waves, after the noise sound waves in the flow air duct 41 and the air outlet cavity 51 encounter the protrusions 31 and are blocked, they will be reflected between multiple protrusions 31 or between the protrusions 31 and the inner wall surface of the flow air duct 41 or the inner wall surface of the air outlet cavity 51, effectively reducing the energy of the noise sound waves. And after multiple reflections by the multiple protrusions 31, it can greatly weaken the energy of the noise sound waves in the flow air duct 41 and the air outlet cavity 51, thereby reducing the noise value in the flow air duct 41 and the air outlet cavity 51 and weakening abnormal sounds, improving the user experience and comfort, and being able to meet the noise standard while facilitating the improvement of the air volume of the air treatment module 100 and the rotation speed of the wind wheel 20, meeting the required usage requirements.

[0092] In some embodiments, as Figures 2 - 5 、 Figures 18 - 21 shown, the housing 10 further includes an air inlet air duct member 80. The air inlet air duct member 80 has an air inlet cavity 82, an air suction port 12 and an air inlet 81. The air suction port 12 and the air inlet 81 are communicated with the air inlet cavity 82, and the air inlet 81 is communicated with the fan air inlet 43.

[0093] Thus, under the driving action of the wind wheel 20, the air flow can enter the air inlet cavity 82 through the air suction port 12 and flow out through the air inlet 81, so that the flowing air flow can enter the flow air duct 41 through the fan air inlet 43 and flow out through the fan air outlet 42. The flowing air flow further enters the air outlet cavity 51 through the communication port 52 and flows out through the air supply port 13, which can realize the flow and guidance of the air flow, meet the required air flow demand, facilitate the entry and guidance of the air flow, change the air flow direction in the air duct 11, and facilitate the control of the air flow.

[0094] In some embodiments of the present invention, as Figures 5 - 11 shown, when at least part of the inner wall surface of the flow air duct 41 is provided with a noise reduction structure 30, the volute 40 includes a volute body 401 and a diffuser section 402. The volute body 401 is provided with a fan air inlet 43, and the wind wheel 20 is arranged in the volute body 401, which is convenient for placing the wind wheel 20. One end of the diffuser section 402 is connected to the volute body 401, and the other end of the diffuser section 402 forms a fan air outlet 42. The volute body 401 and the diffuser section 402 define the flow air duct 41. The diffuser section 402 is convenient for guiding the air flow, which is beneficial to increasing the air output and meeting the required usage requirements.

[0095] At the same time, as Figure 3 、 Figures 5 - 11As shown, the noise reduction structure 30 is provided on at least a part of the inner wall surface of the diffuser section 402. When the noise sound waves in the flow air duct 41 propagate along the air flow direction in the flow air duct 41, the air flow flows out through the diffuser section 402. After the outflowing noise sound waves encounter the protrusions 31 and are blocked, they will be reflected between multiple protrusions 31 or between the protrusions 31 and the inner wall surface of the diffuser section 402, effectively reducing the energy of the noise sound waves. And after multiple reflections by the multiple protrusions 31, it can greatly weaken the energy of the outflowing noise sound waves, thereby reducing the noise value and weakening abnormal sounds, improving the user experience and comfort, and ensuring good noise reduction effect of the air treatment module 100, which is beneficial to reducing production costs.

[0096] In some embodiments, as Figure 6 shown, the impeller 20 may include a motor 21, an impeller body 22 and a motor housing 23. The motor 21 is arranged inside the motor housing 23. The motor housing 23 can play a role in fixing, limiting and protecting the motor 21. The motor housing 23 and the impeller body 22 are arranged inside the volute 40. The volute 40 can play a role in limiting and protecting the motor housing 23 and the impeller body 22. The output shaft of the motor 21 extends out of the motor housing 23 and is connected to the impeller body 22. The motor 21 can drive the impeller body 22 to rotate through the output shaft. Thus, the impeller 20 can realize the forced flow of the air flow to meet the required air flow demand. For example, the impeller 20 can be a centrifugal impeller 20.

[0097] In some embodiments, as Figure 6 shown, the motor housing 23 may include a first cover body 231 and a second cover body 232. The first cover body 231 and the second cover body 232 are connected. The motor 21 is arranged between the first cover body 231 and the second cover body 232. The output shaft of the motor 21 extends out of the first cover body 231 and is connected to the impeller body 22, which is convenient for connecting the motor 21 and the impeller body 22 to meet the required connection demand.

[0098] According to some embodiments of the present invention, as Figure 3 、 Figures 5 - 11 、 Figures 17 - 26 shown, part or all of the inner wall surface of the air duct 11 is provided with the noise reduction structure 30, which can be set according to different situations to meet different noise reduction requirements.

[0099] In the embodiments of the present invention, the specific structure and installation method of the noise reduction structure 30 can be set according to the actual situation.

[0100] For example, in some embodiments, the housing 10 and the noise reduction structure 30 can be an integral part, which is simple to manufacture, has high connection strength, reduces the assembly process, and improves production efficiency.

[0101] For example, in some embodiments, as Figure 3 , Figures 5 - 11 , Figures 17 - 26 shown, the noise reduction structure 30 can include a patch 32, the patch 32 is connected to the inner wall surface of the air duct 11 to ensure that the noise reduction structure 30 is reliably fixed on the inner wall surface of the air duct 11. The protrusion 31 is provided on the wall surface of the patch 32 facing the center of the air duct 11, which facilitates the reflection of the noise sound waves in the air duct 11 between the plurality of protrusions 31 or between the protrusion 31 and the inner wall surface of the air duct 11, effectively reducing the energy of the noise sound waves, reducing the noise value of the air duct 11 and weakening abnormal sounds, and improving the user experience and comfort. At the same time, the structure of the noise reduction structure 30 is simple, which is convenient for processing and manufacturing, and is beneficial to reducing the structural complexity.

[0102] For example, in some embodiments, the housing 10 has a notch communicating with the air duct 11, the patch 32 is provided at the notch, and the patch 32 seals the notch, so that the noise reduction structure 30 can be formed as a part of the defined air duct 11, and can meet the requirement of reducing the energy of the noise sound waves, meet different usage requirements, and reduce production costs.

[0103] In some embodiments of the present invention, as Figures 3 - 30 shown, the housing 10 and the patch 32 are detachably connected, which is convenient for assembling the housing 10 and the patch 32, is beneficial to improving the assembly efficiency, and is convenient for disassembly.

[0104] In some embodiments, as Figure 8 and Figure 24 shown, the housing 10 and the patch 32 are connected by snap connection to ensure reliable connection between the housing 10 and the patch 32, so that the noise reduction structure 30 is reliably fixed on the housing 10, which is beneficial to improving the assembly efficiency, is convenient for disassembly, and can reduce production costs.

[0105] In some embodiments, as Figure 9 , Figure 10 , Figure 24 and Figure 25 shown, the housing 10 and the patch 32 are connected by a fastener 93 to ensure reliable connection between the housing 10 and the patch 32, so that the noise reduction structure 30 is reliably fixed on the housing 10, which is beneficial to improving the assembly efficiency, is convenient for disassembly, and can reduce production costs. For example, the fastener 93 can be a screw.

[0106] For example, in some embodiments, as Figure 8 , Figure 11 , Figures 12 - 16 , Figures 24 - 31As shown, the patch 32 may include a snap 94, and the housing 10 may include a slot 92. Thus, the snap 94 can be snapped into the slot 92. Through the cooperation of the snap 94 and the slot 92, the patch 32 is connected to the housing 10 and is easy to disassemble.

[0107] In some embodiments, such as Figure 8 , Figure 11 , Figures 12 - 16 , Figures 24 - 31 As shown, there may be multiple (greater than or equal to two) snaps 94. The multiple snaps 94 are spaced apart on the patch 32. There are multiple slots 92. The multiple slots 92 cooperate with the multiple snaps 94. By the one-to-one correspondence between the multiple slots 92 at different positions and the snaps 94, the fixation of different positions of the patch 32 and the housing 10 can be realized, ensuring reliable fixation.

[0108] In some embodiments, such as Figure 8 , Figure 11 , Figures 12 - 16 , Figures 24 - 31 As shown, the patch 32 further includes a limit post 95. Limit posts 95 are provided on both sides in the width direction of the snap 94. The limit posts 95 can pass through the slot 92 so that the limit posts 95 can abut against the side wall of the slot 92, avoiding damage caused by the snap 94 being stressed, etc., which is beneficial to extending the service life and improving the user experience.

[0109] For example, in some embodiments, such as Figure 9 , Figure 10 , Figure 24 and Figure 25 As shown, the housing 10 may include a first mounting hole 91, the patch 32 may include a second mounting hole 96, and a fastener 93 can pass through the second mounting hole 96 to connect with the first mounting hole 91, so that the patch 32 is connected to the housing 10, ensuring reliable fixation of the patch 32 on the housing 10 and being easy to disassemble.

[0110] In some embodiments, such as Figure 9 , Figure 10 , Figure 24 and Figure 25 As shown, there may be multiple (greater than or equal to two) first mounting holes 91. The multiple first mounting holes 91 are spaced apart on the housing 10. There are multiple second mounting holes 96. The multiple second mounting holes 96 cooperate with the multiple first mounting holes 91. By the one-to-one correspondence between the multiple second mounting holes 96 at different positions and the first mounting holes 91, the fixation of different positions of the patch 32 and the housing 10 can be realized, ensuring reliable fixation.

[0111] In some embodiments where a noise reduction structure 30 is provided on at least a part of the inner wall surface of the flow air duct 41, such as Figures 8 - 16As shown, the volute 40 may include a clamping groove 92 and a first mounting hole 91, and the patch 32 may include a buckle 94 and a second mounting hole 96. The buckle 94 is snapped into the clamping groove 92, and a fastener 93 passes through the second mounting hole 96 to be connected to the first mounting hole 91, fixing the patch 32 on the volute 40, ensuring reliable fixation of the patch 32 on the volute 40 and facilitating disassembly.

[0112] In some embodiments, as Figures 6 - 13 shown, in the thickness direction of the volute 40 (e.g., the front-back direction shown in Figure 6 ), the volute 40 includes a first volute 45 and a second volute 46. The first volute 45 and the second volute 46 are snap-connected to define a flow air duct 41. The wind wheel 20 is arranged between the first volute 45 and the second volute 46. A fan air inlet 43 is provided on the first volute 45, and the first volute 45 and the second volute 46 define a fan air outlet 42, facilitating placement of the wind wheel 20 and being conducive to reducing the structural complexity of the volute 40.

[0113] In addition, as Figures 8 - 16 shown, both the first volute 45 and the second volute 46 include a clamping groove 92 and a first mounting hole 91. The number of patches 32 is multiple, and each of the multiple patches 32 includes a buckle 94 and a second mounting hole 96. The buckles 94 of some of the patches 32 cooperate with the clamping grooves 92 of the first volute 45, and the buckles 94 of some other patches 32 cooperate with the clamping grooves 92 of the second volute 46. The number of fasteners 93 is multiple. Some of the fasteners 93 respectively pass through the second mounting holes 96 of some of the patches 32 to be connected to the corresponding first mounting holes 91 of the first volute 45, and some other fasteners 93 respectively pass through the second mounting holes 96 of some other patches 32 to be connected to the corresponding first mounting holes 91 of the second volute 46, enabling the multiple patches 32 to be respectively fixed on the first volute 45 and the second volute 46, and ensuring reliable fixation of the multiple patches 32 on the first volute 45 and the second volute 46.

[0114] It should be noted that for ease of description, the orientations such as "front-back direction" and "left-right direction" in the present invention are based on the orientation relationships shown in the drawings, rather than limitations on the orientations in the actual application process.

[0115] In the embodiments of the present invention, the number of patches 32 can be flexibly set according to actual situations. For example, the number of patches 32 can be six as Figure 6 shown, or can be two, three, four, five, seven or more, which are all within the protection scope of the present invention.

[0116] In some embodiments, as Figure 5 , Figure 7 , Figure 12 and Figure 21As shown, a volute tongue 44 is provided on the hole wall of the air inlet 43 of the fan. The volute tongue 44 is arranged around the circumferential direction of the hole wall of the air inlet 43 of the fan. During the rotation of the impeller 20, the volute tongue 44 can guide the air flow in the volute 40, facilitating the impeller 20 to send the air flow in the volute 40 radially to the air duct 11, making the air flow reliable.

[0117] In some embodiments where a noise reduction structure 30 is provided on at least part of the inner wall surface of the air outlet cavity 51, such as Figures 22 - 31 As shown, the air outlet duct member 50 may include a card slot 92 and a first mounting hole 91. The patch 32 may include a buckle 94 and a second mounting hole 96. The buckle 94 is snapped into the card slot 92, and a fastener 93 is passed through the second mounting hole 96 to connect with the first mounting hole 91, fixing the patch 32 on the air outlet duct member 50, ensuring that the patch 32 is reliably fixed on the air outlet duct member 50 and facilitating disassembly.

[0118] In some embodiments, such as Figures 22 - 28 As shown, the air outlet duct member 50 may include a first housing body 501 and a second housing body 502. The first housing body 501 and the second housing body 502 are connected to each other to define an air outlet cavity 51. The communication port 52 and the air supply port 13 are both provided on the first housing body 501, which is beneficial to reducing the structural complexity of the air outlet duct member 50 and facilitating the processing and manufacturing of the air outlet duct member 50.

[0119] In addition, as Figures 22 - 28 shown, both the first housing body 501 and the second housing body 502 include a card slot 92 and a first mounting hole 91. There are multiple patches 32, and each of the multiple patches 32 includes a buckle 94 and a second mounting hole 96. The buckles 94 of some of the patches 32 cooperate with the card slots 92 of the first housing body 501, and the buckles 94 of some other patches 32 cooperate with the card slots 92 of the second housing body 502. And there are multiple fasteners 93. Some of the fasteners 93 are respectively passed through the second mounting holes 96 of some of the patches 32 to connect with the corresponding first mounting holes 91 of the first housing body 501, and some other fasteners 93 are respectively passed through the second mounting holes 96 of some other patches 32 to connect with the corresponding first mounting holes 91 of the second housing body 502, enabling the multiple patches 32 to be respectively fixed on the first housing body 501 and the second housing body 502, and ensuring that the multiple patches 32 are reliably fixed on the first housing body 501 and the second housing body 502.

[0120] In the embodiments of the present invention, the number of the patches 32 can be flexibly set according to actual situations. For example, the patches 32 can be Figure 22 seven as shown, or can be two, three, four, five, six, eight or more, which are all within the protection scope of the present invention.

[0121] According to some embodiments of the present invention, as Figure 8 , Figure 9 , Figure 24 , Figure 31 shown in Figure 33 , a sound-absorbing member 33 is provided on the outer peripheral wall of the protrusion 31. Through the sound-absorbing member 33, the energy of the noise sound wave can be absorbed, thereby reducing the energy of the noise sound wave, further weakening the energy of the noise sound wave in the air duct 11, reducing the noise value of the air duct 11 and weakening abnormal sounds, and improving the user experience and comfort. For example, the sound-absorbing member 33 is flannelette or sound-absorbing cotton, etc.

[0122] In some embodiments of the present invention, as Figures 7 - 10 , Figures 14 - 16 , Figures 23 - 25 , Figure 29 , Figures 13 - 33 shown in Figure 33 , in the direction from the fixed end to the free end of the protrusion 31, the cross-sectional area of the protrusion 31 gradually decreases. Thus, the area for the protrusion 31 to receive the energy of the noise sound wave can be increased, so that the energy of the noise sound wave can be reflected multiple times between multiple protrusions 31, effectively weakening the energy of the noise sound wave in the air duct 11, reducing the noise value of the air duct 11 and weakening abnormal sounds. For example, the reflection path of the energy of the noise sound wave can be as shown by the arrow in Figure 33 .

[0123] According to some embodiments of the present invention, as Figure 33 shown in

[0124] , in any cross-section parallel to the height direction of the protrusion 31, the angle between at least one of the opposite side walls of the protrusion 31 and the height direction of the protrusion 31 is a, and a satisfies: 5° < a < 30°. Thus, when the angle between at least one of the opposite side walls of the protrusion 31 and the height direction of the protrusion 31 is within the above range, the opposite side walls of the protrusion 31 can be inclined, and the required height requirement of the protrusion 31 can be satisfied, so that the energy of the noise sound wave can be reflected multiple times between multiple protrusions 31, effectively weakening the energy of the noise sound wave in the air duct 11, reducing the noise value of the air duct 11 and weakening abnormal sounds, and facilitating demolding, making the processing convenient. For example, in some specific embodiments, in any cross-section parallel to the height direction of the protrusion 31, the angle a between at least one of the opposite side walls of the protrusion 31 and the height direction of the protrusion 31 can be 6°, 6.5°, 8°, 10°, 15°, 20°, 25°, 29°, etc.

[0124] In some embodiments, as Figure 33 shown in , whether the angles between the opposite side walls of the protrusion 31 and the height direction of the protrusion 31 are the same or different, they can both meet the requirement for the energy of the noise sound wave to be reflected between multiple protrusions 31, and different processing and manufacturing of the protrusion 31 can be carried out to meet different use requirements.

[0125] In some embodiments of the present invention, such as Figure 3 and Figure 19 shown, the angle between at least one surface of the outer peripheral wall of the protrusion 31 and the flow direction of the air flow is an acute angle, which can avoid the protrusion 31 from blocking the flow of the air flow, facilitate the guiding of the air flow, effectively reduce the wind resistance, avoid the loss of the air flow, and ensure the working efficiency of the air handling module 100. For example, as Figure 3 and Figure 19 shown, the flow direction of the air flow is from bottom to top.

[0126] According to some embodiments of the present invention, such as Figure 32 and Figure 33 shown, the protrusion 31 can be formed as a frustum of a quadrangular pyramid, which can increase the area for the protrusion 31 to receive the noise sound wave energy, so that the noise sound wave energy can be reflected multiple times between multiple protrusions 31, effectively weaken the energy of the noise sound wave in the air duct 11, reduce the noise value of the air duct 11 and weaken the abnormal sound, and the structure of the protrusion 31 is simple and convenient for processing and manufacturing.

[0127] In some embodiments of the present invention, the air handling module 100 is at least one of a fresh air module, a humidifying module, and a purifying module. In other words, the air handling module 100 can be a fresh air module, a humidifying module, or a purifying module; or, the air handling module 100 can be two of the fresh air module, the humidifying module, and the purifying module; or, the air handling module 100 can be the fresh air module, the humidifying module, and the purifying module. Different air handling modules 100 can be selected according to the actual needs of different air handling devices to meet different usage requirements.

[0128] The fresh air device can introduce outdoor fresh air into the room, drive the air circulation in the room, and perform air exchange in the room, which is beneficial to ensuring the fresh air in the room; the humidifying module can humidify the air flow, so that the air flow with humidity blows into the room, increasing the water vapor content in the room and achieving the humidifying effect on the room; the purifying module can purify the air flow, so that the purified air flow blows into the room, improving the air quality.

[0129] In some embodiments where the air handling module 100 is a purifying module, such as Figure 3 , Figure 19 and Figure 22 shown, the air handling module 100 further includes a purification net 53, which is arranged in the air duct 11 and is located downstream of the wind wheel 20. The air flow entering from the air inlet 12 can be purified by the purification net 53, and the purified air flow can flow out to the room through the air outlet 13, realizing the purification requirement of the air flow.

The housing 60 has an air inlet 61 and an air outlet 62. The air inlet 61 is opposite to and communicated with the air suction port 12, and the air outlet 62 is opposite to and communicated with the air supply port 13, so that air flow can enter the air treatment module 100 through the air inlet 61 and the air suction port 12, and the air flow processed within the air treatment module 100 can flow out through the air supply port 13 and the air outlet 62 to meet the user's usage requirements.

[0131] Since the air treatment module 100 according to the embodiment of the present invention has the above beneficial technical effects, in the air conditioner 200 according to the embodiment of the present invention, a wind wheel 20 is disposed within the air duct 11 for driving the air flow to flow from the air suction port 12 to the air supply port 13, and a noise reduction structure 30 is disposed on the inner wall surface of the air duct 11. The noise reduction structure 30 includes a plurality of spaced-apart protrusions 31, such that the noise sound waves within the air duct 11 can be reflected multiple times between the plurality of protrusions 31 or between the protrusions 31 and the inner wall surface of the air duct 11, effectively reducing the energy of the noise sound waves, being able to greatly weaken the energy of the noise sound waves within the air duct 11, thereby reducing the noise value of the air duct 11 and weakening abnormal sounds, enhancing the user's experience and comfort, and the structure of the noise reduction structure 30 is simple and convenient for processing and manufacturing.

[0132] In some embodiments where the outer casing 10 includes a volute 40, as Figure 6 shown, the outer casing 10 further includes a mounting bracket 47. The two ends of the mounting bracket 47 are respectively connected to the volute 40 and the housing 60, which can fix the air treatment module 100, ensure reliable fixation of the air treatment module 100, and is convenient for installation, can reduce the structural complexity of the volute 40, and is convenient for processing and manufacturing.

Through the plurality of air inlets 61 and air suction ports 12, the air intake volume of the air conditioner 200 can be increased, ensuring reliable operation of the air conditioner 200, and being beneficial to improving work efficiency.

[0134] In the embodiment of the present invention, the number of the air suction ports 12 can be flexibly set according to actual situations. For example, the air suction ports 12 can be Figure 2 shown as two, or can be three, four, five, six or more, which are all within the protection scope of the present invention.

[0135] In some embodiments, asFigures 1 - 3 , Figures 17 - 19 As shown in Figures 17 - 19 , there are multiple air supply outlets 13 spaced apart on the housing 10, and there are multiple air outlet openings 62 corresponding to the air supply outlets 13 one by one. Through the multiple air supply outlets 13 and the air outlet openings 62, the air supply range of the air conditioner 200 can be increased, the air supply volume can be effectively increased, the use comfort can be improved, and thus the user experience can be improved.

[0136] In the embodiment of the present invention, the number of the air supply outlets 13 can be flexibly set according to the actual situation. For example, the air supply outlets 13 can be Figure 2 as shown in Figure 2 and be two, or can be three, four, five, six or more, and all of these are within the protection scope of the present invention.

For example, the heat exchange component 72 can be an evaporator.

[0138] In some embodiments, as Figures 1 - 3 , Figures 17 - 19 shown in Figures 17 - 19 , the heat exchange component 72 is located above the air treatment module 100. Through the heat exchange component 72, the air can be heat-exchanged, and through the air treatment module 100, different air treatment requirements can be realized, different use requirements can be met, the user experience can be improved, and the structure is compact, which is beneficial to reducing the occupied space.

[0139] In some embodiments, as Figure 1 , Figure 2 , Figure 17 and Figure 18 shown in Figure 17 and Figure 18 , the air treatment device further includes an air outlet frame 70. The air outlet frame 70 is provided inside the housing 60. The air outlet frame 70 and the housing 60 jointly define a heat exchange air duct 71.

At the same time, switch doors are respectively provided on both sides in the width direction of the air outlet frame 70 (for example, the left and right directions shown in Figure 1 ). The two switch doors are respectively movably provided at the two air duct air outlets 69. The two switch doors can respectively open or close the air duct air outlets 69. Through the air outlet frame 70, it is convenient to install the two switch doors to ensure that the switch doors are fixed reliably.
