[0057] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0058] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides various specific processes and examples of materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.

[0059] Next, an air outlet frame component 100 according to an embodiment of the first aspect of the present invention will be described with reference to the accompanying drawings.

[0060] The air outlet frame component 100 of the embodiment of the present invention is applied to air supply equipment. By way of example, the air supply equipment includes but is not limited to various types of air conditioners with temperature regulation capabilities, such as wall-mounted air conditioners, cabinet air conditioners, mobile air conditioners, window air conditioners, fresh air fans, duct air conditioners, etc., and may also include other types of air supply equipment that do not have temperature regulation capabilities.

[0061] like Figure 1 As shown, the air outlet frame component 100 includes: an air outlet frame 1 and a noise reduction component 2. An air outlet duct 10 is formed in the air outlet frame 1. The noise reduction component 2 includes at least one sound absorbing board 21. The sound absorbing board 21 is arranged in the air outlet frame 1 near the inner wall surface 16. The opposite sides of the sound absorbing board 21 face the inner wall surface 16 and the air outlet duct 10 respectively. The opposite sides of the sound absorbing board 21 mentioned here refer to the opposite sides of the sound absorbing board 21 in its own thickness direction Z. The side of the sound absorbing board 21 facing the air outlet duct 10 is the windward side, and the side of the sound absorbing board 21 facing the inner wall surface 16 is the leeward side.

[0062] The airflow flows through the air outlet frame 1 and along the air outlet duct 10 in the air outlet frame 1. In this process, the air outlet frame 1 changes the flow path of the airflow so that the airflow is blown out from the set air outlet 10a. In some solutions, the function of the air outlet frame 1 is not limited to changing the flow path of the airflow, but the airflow can be purified, humidified, scented, and temperature-adjusted in the air outlet frame 1. One or more measures are also used to treat the airflow, thereby adjusting the air state of the air outlet to meet the specific comfort needs of different users.

[0063] In the related art, when the airflow enters the air outlet frame, noise will be generated on the airflow path due to the friction between the airflow and the components it flows through, the shaking of the components caused by the airflow, the friction between the spoiler groups generated in the airflow, etc. The noise is particularly obvious when the airflow volume is large, and a cavity abnormal sound similar to "boiling water" will be generated. In view of the above problems, the air outlet frame component 100 of the embodiment of the present invention is provided with a noise reduction component 2, and a sound absorbing plate 21 is arranged close to the inner wall surface 16 of the air outlet frame 1 to reduce the noise in the air outlet frame 1. As a result, the airflow noise of the air outlet frame component 100 is low, which can improve the comfort of use of the air outlet frame component 100.

[0064] like Figure 2-Figure 4 As shown, the sound absorbing plate 21 is provided with a sound absorbing hole 214 extending along the thickness direction Z of the sound absorbing plate 21. The sound absorbing plate 21 includes a first plate area 211 and a second plate area 212. The first plate area 211 is multiple, and the first plate area 211 protrudes toward the air outlet duct 10, so that the first plate area 211 forms a first silencer groove 31 on the side facing the inner wall surface 16, and at least one sound absorbing hole 214 is connected to the first silencer groove 31. The second plate area 212 is between two adjacent first plate areas 211. Correspondingly, the second plate area 212 is also multiple, and between two adjacent first plate areas 211, the second silencer groove 32 is formed on the side of the second plate area 212 facing the air outlet duct 10. In other words, the second silencer groove 32 on the sound absorbing plate 21 is arranged to face the wind, while the first silencer groove 31 is arranged to leeward.

[0065] When the sound is transmitted to the sound absorbing panel 21 along with the air flow, the sound is divided into multiple sections by the sound absorbing panel 21, and the sound wave energy of each section is greatly weakened. Some sound waves are facing the first panel area 211, and part of these sound waves are reflected by the first panel area 211. Some sound waves are facing the second panel area 212, and part of these sound waves are reflected by the second panel area 212.

[0066] There is usually a certain phase difference between the sound waves reflected from the first panel area 211 and the sound waves reflected from the second panel area 212. When the sound waves reflected from the first panel area 211 and the sound waves reflected from the second panel area 212 meet during propagation, the amplitude of the sound waves can be weakened to a certain extent. In addition, since the plurality of first panel areas 211 and the plurality of second panel areas 212 are arranged at intervals, the reflected sound waves with a phase difference can be weakened over a large area on the windward side of the sound absorbing panel 21.

[0067] Since the sound absorbing plate 21 forms a plurality of second silencer grooves 32 on the windward side, the sound waves diverted into each second silencer groove 32 will be reflected when hitting the bottom wall of the second silencer groove 32, and will also be reflected when hitting the side wall of the second silencer groove 32. In particular, the sound waves reflected by the side walls on both sides of the second silencer groove 32 will propagate toward the middle of the second silencer groove 32, and the two will not only meet each other but also meet the sound waves reflected by the bottom wall of the second silencer groove 32, and the three will consume each other.

[0068] The sound absorbing plate 21 is provided with a sound absorbing hole 214, which can quickly reduce noise. Specifically, when noise enters the sound absorbing hole 214, it generates eddy currents, which consumes part of the sound energy. Moreover, after the noise enters the sound absorbing hole 214, the sound hits the wall and is reflected. The incident sound wave and the reflected sound wave are superimposed in the sound absorbing hole 214, and they are easy to cancel each other out when superimposed to reduce noise. In addition, the noise enters the sound absorbing hole 214 once, and the sound pressure changes once. After the noise is reflected, it is discharged from the sound absorbing hole 214, and the sound pressure changes again. The noise energy can also be reduced in the process of entering and exiting.

[0069] It is worth noting that at least part of the sound absorbing holes 214 are through holes, and the sound absorbing holes 214 penetrate the sound absorbing board 21 along the thickness direction Z of the sound absorbing board, so that at least part of the sound absorbing holes 214 are connected to the first muffler groove 31. Optionally, part of the sound absorbing holes 214 can be set as blind holes.

[0070] The specific shape and size of the sound absorbing holes 214 are not specifically limited here, and the shape of the sound absorbing holes 214 can be circular, square, long strip, etc. Of course, the area and number of the sound absorbing holes 214 on the sound absorbing plate 21 can also be set as needed.

[0071] Since at least one sound-absorbing hole 214 is connected to the first silencer groove 31, the first silencer groove 31 is arranged toward the inner wall surface 16, and the sound-absorbing hole 214 connects the first silencer groove 31 with the air outlet duct 10, the first silencer groove 31 can not only play the role of noise reduction of the sound-absorbing hole 214, but also play the role of an air cavity, and the sound-absorbing hole 214 and the cavity of the first silencer groove 31 form a Helmholtz silencer. The sound-absorbing hole 214 and the cavity constitute a resonance structure, and when the inflowing sound wave has the same resonance frequency as the resonance structure, the air in the first silencer groove 31 will produce a fierce friction effect, consume sound energy, play a sound absorption effect, and further enhance the sound absorption and noise reduction effect.

[0072] Another part of the sound waves will propagate along the thickness direction Z of the sound absorbing board 21 when encountering the sound absorbing board 21. Since the sound waves consume a lot of energy when passing through different propagation media, this part of the sound waves consumes a lot of energy.

[0073] It is worth noting that the sound-absorbing panel 21 can be a single structural panel. For example, the sound-absorbing panel 21 can be an aluminum panel, a steel panel, a galvanized panel, a stainless steel panel, a plastic panel, etc. The sound-absorbing panel 21 can also be a composite panel structure, and the sound-absorbing material is filled inside the sound-absorbing panel 21. For example, the sound-absorbing panel 21 is a composite panel of a plastic panel and sound-absorbing cotton, which falls within the protection scope of the present invention. At this time, when the sound-absorbing panel 21 is a composite panel, each time the sound wave passes through the propagation medium, it will be weakened by one layer, so the ability to weaken the sound wave can be enhanced when the number of layers increases.

[0074] In addition, compared to a straight plate-shaped sound absorbing panel, the sound absorbing panel 21 of the present invention has a bent structure along the thickness direction Z of the sound absorbing panel, which can improve the structural strength of the sound absorbing panel 21, so as to improve the working stability of the air outlet frame component 100 in harsh environments. In this way, the vibration amplitude generated by the sound absorbing panel 21 when air flows through is smaller, and the noise generated by the vibration will also be less.

[0075] Therefore, the noise reduction component 2 provided in the present application can significantly reduce the noise of the air outlet frame component 100, and this noise reduction effect is stronger than the noise reduction effect of each single structure.

[0076] According to the air outlet frame member 100 of the embodiment of the present invention, the airflow noise of the air outlet frame member 100 can be reduced by providing the noise reduction component 2, and the working noise of the air outlet frame member 100 can be reduced. In addition, by configuring the sound absorbing plate 21 to have a bent structure along the thickness direction, a plurality of first silencer grooves 31 and a plurality of second silencer grooves 32 are formed, and the noise reduction component 2 has a good sound absorption and noise reduction effect, and the noise of the air outlet frame member 100 is further reduced.

[0077] In some embodiments of the present invention, the first plate area 211 is in the shape of a strip or a ring, and the second plate area 212 is in the shape of a corresponding strip or a ring. It is worth noting that the first plate area 211 and the second plate area 212 are in the shape of a strip or a ring, which refers to the extension direction of the plate surface of the first plate area 211 and the second plate area 212. For example, Figure 2 As shown, the board surfaces of the first board area 211 and the second board area 212 extend along the length direction X of the sound absorbing board, and the first board area 211 and the second board area 212 are sequentially arranged along the width direction Y of the sound absorbing board.

[0078] The long strip here is understood in a broad sense. The long strip may be a strip extending along a straight line, a strip with a curvature extending along an arc line, or a curved strip extending along a wave shape.

[0079] Optionally, the first panel area 211 may be a long strip that is not connected end to end, and correspondingly, the second panel area 212 is also a long strip that is similar in shape and is not connected end to end. Optionally, the first panel area 211 may be a ring that is connected end to end, and correspondingly, the second panel area 212 is also a ring that is connected end to end, so that the sound absorbing panel 21 is constructed as a ring structure that is sequentially set.

[0080] In some embodiments of the present invention, the plate surface of the first plate area 211 is a flat surface or an arc surface; the plate surface of the second plate area 212 is a flat surface or an arc surface. It can be understood that the first silencer groove 31 is formed between the first plate area 211 and the inner wall surface 16, so the first plate area 211 forms the bottom wall of the first silencer groove 31, and correspondingly, the second plate area 212 forms the bottom wall of the second silencer groove 32.

[0081] Optionally, the plate surface of the first plate area 211 is a flat surface, and further optionally, the plate surface of the first plate area 211 is a curved surface; optionally, the plate surface of the second plate area 212 is a flat surface, and further optionally, the plate surface of the second plate area 212 is a curved surface. The shapes of the plate surfaces of the first plate area 211 and the second plate area 212 can be selected according to actual needs.

[0082] For example, for example, Figure 2 and Figure 5 As shown, the first plate area 211 and the second plate area 212 are both flat surfaces, and the first plate area 211 and the second plate area 212 are parallel to each other. The sound absorbing panel 21 has a simple structure and is easy to manufacture.

[0083] For example, the first panel area 211 and the second panel area 212 are both arc-shaped surfaces, so that the sound absorbing panel 21 is constructed as a sine-cosine curve along the thickness direction Z of the sound absorbing panel. Sound waves can be reflected back and forth on the curved surface and cancel each other out, further improving the sound absorption and noise reduction effect of the sound absorbing panel 21.

[0084] In some embodiments of the present invention, Figure 4 As shown, the width dimension B of the first plate area 211 is 5 mm to 30 mm, for example, 5 mm, 9 mm, 10 mm, 18 mm, 25 mm, 30 mm, etc.

[0085] When the width of the first plate area 211 is too large, the size of the first silencer groove 31 is too large, and the noise reduction effect of the sound waves rubbing back and forth in the second silencer groove 32 is weakened; when the width of the first plate area 211 is too small, the size of the first silencer groove 31 is too small, which will increase the difficulty of manufacturing the sound absorbing panel 21.

[0086] By setting the width B of the first plate area 211 to the above size range, not only the noise reduction effect of the first silencer groove 31 can be improved, but also the manufacturing difficulty of the sound absorbing plate 21 can be reduced. Preferably, the width B of the first plate area 211 is 18 mm.

[0087] In some embodiments of the present invention, Figure 4 As shown, the width dimension A of the second silencing groove 32 is 5 mm to 20 mm, for example, 5 mm, 6 mm, 10 mm, 12 mm, 15 mm, 20 mm, etc.

[0088] Similarly, by setting the width dimension A of the second silencer groove 32 to the above dimension range, not only the noise reduction effect of the second silencer groove 32 can be improved, but also the manufacturing difficulty of the sound absorbing plate 21 can be reduced. Preferably, the width dimension A of the second silencer groove 32 is 12 mm.

[0089] In some embodiments of the present invention, Figure 4 As shown, the depth dimension C of the second silencing groove 32 is 5 mm to 20 mm, for example, 5 mm, 7 mm, 12 mm, 15 mm, 19 mm, 20 mm, etc.

[0090] It can be understood that the depth dimension C of the second silencer groove 32 and the depth dimension of the first silencer groove 31 are both defined by the spacing between the first plate area 211 and the second plate area 212 in the thickness direction Z of the sound absorbing board, and the depth dimension of the second silencer groove 32 also defines the depth dimension of the first silencer groove 31. When the depth dimension C of the second silencer groove 32 is too large, the thickness dimension of the sound absorbing board 21 is too large, and the sound absorbing board 21 is arranged in the air outlet frame 1, which will occupy the spatial volume of the air outlet duct 10, affecting the air outlet volume of the air outlet frame component 100. When the depth dimension C of the second silencer groove 32 is too small, the sound absorption and noise reduction capability will be reduced.

[0091] In this way, the depth dimension C of the second silencer groove 32 is shallow, which reduces the probability of turbulence in the second silencer groove 32 and reduces the energy loss of the airflow passing through the sound absorbing plate 21. Moreover, the human ear is more sensitive to noise of 1000-4000 Hz.

[0092] From the generally accepted sound frequency range, it can be seen that the depth dimension C of the second silencer groove 32 is limited to 5mm to 20mm, which can make the sound waves reflected by the first plate area 211 and the second plate area 212 generally produce a phase difference of 10° to 170°. When the noises are superimposed on each other, the phase difference has an obvious tendency to weaken each other, thereby greatly reducing the noise.

[0093] Preferably, the depth of the second muffler groove 32 is 10 mm.

[0094] In some embodiments of the present invention, Figure 3 and Figure 4As shown, the first plate area 211 and the second plate area 212 are parallel, and the edge of the first plate area 211 is connected to the second plate area 212 through the third plate area 213 arranged vertically to form a whole. The first plate area 211 and the second plate area 212 are both arranged parallel to the inner wall surface 16 close to the sound absorbing plate 21, and the sound absorbing plate 21 can be approximately regarded as a straight plate portion. The sound absorbing plate 21 is arranged parallel to the inner wall surface 16, which is convenient for arrangement, and can reduce the space occupied by the air outlet duct 10 and reduce the impact on the air outlet frame component 100.

[0095] In some specific embodiments of the present invention, Figure 2 and Figure 5 As shown, the first plate area 211 and the second plate area 212 are both straight strips, the first plate area 211 and the second plate area 212 are both flat surfaces, and the first plate area 211 and the second plate area 212 are parallel. Figure 4 As shown, the first panel area 211 and the second panel area 212 are connected by a vertical third panel area 213, the first panel area 211 and the second panel area 212 extend along the length direction X of the sound absorbing board, and the first panel area 211 and the second panel area 212 are sequentially arranged along the width direction Y of the sound absorbing board. The sound absorbing board 21 has good sound absorption and noise reduction effects, and the sound absorbing board 21 has a simple structure and low manufacturing difficulty.

[0096] In some embodiments of the present invention, Figure 4 and Figure 6 As shown, the sound absorbing holes 214 include a first micro hole 2141 opened on the first plate area 211 and a second micro hole 2142 opened on the second plate area 212 . The aperture of the first micro hole 2141 is smaller than or equal to the aperture of the second micro hole 2142 .

[0097] For example, Figure 3 and Figure 5 As shown, the sound absorbing panel 21 arranged at the inner wall surface 16 at the rear of the air outlet duct 10 is taken as an example for explanation. The sound absorbing panel 21 is arranged at the rear of the air outlet duct 10, and the first panel area 211 of the sound absorbing panel 21 located at the inner wall surface 16 at the rear of the air outlet duct 10 is located in front of the second panel area 212, and the aperture of the first micropore 2141 located in the front is less than or equal to the aperture of the second micropore 2142 located in the rear.

[0098] It can be understood that the first plate area 211 is arranged farther from the inner wall surface 16 than the second plate area 212, so the airflow entering the air outlet duct 10 first contacts the first plate area 211, and then contacts the second plate area 212. Correspondingly, the sound wave also contacts the first plate area 211 first, and then contacts the second plate area 212. The aperture of the first micropore 2141 is less than or equal to the aperture of the second micropore 2142. On the same arrangement area, the number of openings of the first micropore 2141 is greater than or equal to the number of openings of the second micropore 2142. Therefore, by setting the aperture of the first micropore 2141 on the first plate area 211 to be less than or equal to the aperture of the second micropore 2142 on the second plate area 212, the number of micropores can be increased, and the sound absorption and noise reduction effect of the sound absorbing panel 21 can be improved.

[0099] It is understandable that small-aperture micropores have a good noise reduction effect on high-frequency noise, and large-aperture micropores have a good noise reduction effect on low-frequency noise. By setting the first micropores 2141 and the second micropores 2142 as sound-absorbing holes 214 with different apertures, the noise reduction effect of the sound-absorbing board 21 on noises of different frequencies can be improved, and the applicability of the sound-absorbing board 21 is wider.

[0100] In some embodiments of the present invention, the aperture of the first micropore 2141 is 4 mm to 6 mm, for example, 4 mm, 4.6 mm, 5 mm, 5.5 mm, 5.8 mm, 6 mm, etc.; the aperture of the second micropore 2142 is 4 mm to 8 mm, for example, 4 mm, 5 mm, 6 mm, 7.5 mm, 8 mm, etc.

[0101] The shapes of the first micropore 2141 and the second micropore 2142 can be circular, square, or long, which are all within the protection scope of the present invention. Preferably, the first micropore 2141 and the second micropore 2142 are circular holes.

[0102] In some embodiments of the present invention, Figure 7 As shown, the sound absorbing board 21 is spaced apart from the inner wall surface 16 to form an air layer 33, and the sound absorbing hole 214 penetrates the sound absorbing board 21 along the thickness direction of the sound absorbing board 21 and communicates with the air layer 33. The sound absorbing hole 214 and the air layer 33 form a resonance structure. When the sound wave enters the air layer 33 through the sound absorbing hole 214, when the sound wave flows into the air layer 33 at the same resonance frequency as the resonance structure, the air in the air layer 33 will produce a fierce friction effect, consume sound energy, and achieve the effect of sound absorption, thereby further improving the sound absorption and noise reduction effect.

[0103] The sound absorbing plate 21 is spaced apart from the inner wall surface 16 to form an air layer 33 , so the second plate area 212 is also spaced apart from the inner wall surface 16 to which it is close, and the first muffler groove 31 and the air layer 33 are connected to form a cavity.

[0104] In some embodiments of the present invention, Figure 8 and Fig. 9 As shown, a socket 11 is provided on the outer surface of the air outlet frame 1 , the socket 11 is connected to the air outlet duct 10 , and the sound absorbing panel 21 is detachably arranged in the air outlet frame 1 via the socket 11 .

[0105] The sound absorbing panel 21 is detachably connected to the air outlet frame 1, which is convenient for disassembly and assembly of the air outlet frame component 100. When the sound absorbing panel 21 is damaged or contaminated, resulting in a decrease in the noise reduction capability, the sound absorbing panel 21 can be disassembled, assembled and replaced, thereby extending the service life of the air outlet frame component 100.

[0106] In some embodiments of the present invention, Figure 2 As shown, the noise reduction component 2 also includes a mounting member 22 connected to the sound absorbing board 21, and the mounting member 22 serves to limit the sound absorbing board 21. When the sound absorbing board 21 is installed in the air outlet frame 1 through the socket 11, the mounting member 22 cooperates with the air outlet frame 1 to position the sound absorbing board 21, thereby improving the working stability of the sound absorbing board 21. In addition, the mounting member 22 can also block the socket 11, thereby preventing the airflow in the air outlet duct 10 from flowing out of the air outlet frame 1 through the socket 11, ensuring that the airflow flows stably along the air outlet duct 10, and avoiding affecting the air outlet effect of the air outlet frame component 100.

[0107] In some embodiments of the present invention, Figure 8 and Fig. 9 As shown, the air outlet frame 1 includes a slide plate 12 disposed in the air outlet duct 10, a slide groove 13 is formed between the slide plate 12 and the inner wall surface 16 where the sound absorbing board 21 is disposed, and the socket 11 is located at one end of the slide groove 13 and is connected to the slide groove 13. The slide groove 13 guides and limits the sound absorbing board 21, and the sound absorbing board 21 extends into the air outlet frame 1 through the socket 11. The slide groove 13 ensures that the sound absorbing board 21 moves smoothly and stably to the working position, improves the movement deviation phenomenon when the sound absorbing board 21 is installed in the air outlet frame 1, and improves the working stability of the sound absorbing board 21.

[0108] In some embodiments of the present invention, the sound absorbing board 21 extends from the socket 11 into the air outlet frame 1 along the length direction of the sound absorbing board 21 , and correspondingly, the slide groove 13 extends along the length direction of the sound absorbing board 21 .

[0109] like Figure 8 and Fig. 9 As shown, the slide groove 13 is located on at least one side of the sound absorbing board 21 in the width direction. Correspondingly, at least one side edge of the sound absorbing board in the width direction Y is inserted into the slide groove 13 .

[0110] It is understandable that the sound absorbing board 21 is used for sound absorption and noise reduction, so the width of the guide plate 12 of the present invention is relatively small and is located at the side of the width direction Y of the sound absorbing board, so that one side of the width direction Y of the sound absorbing board is inserted into the slide groove 13. While the guide plate 12 forms the slide groove 13 to guide and limit the sound absorbing board 21, it also reduces the obstruction of the sound absorbing board 21, ensuring the sound absorption and noise reduction effect of the sound absorbing board 21. Correspondingly, Figure 2 and Fig. 9 As shown, the side edges of the sound absorbing board in the width direction Y that match the slide groove 13 are not provided with sound absorbing holes 214 , which reduces the manufacturing difficulty of the sound absorbing board 21 .

[0111] Optionally, there is one sliding plate 12, and the sliding groove 13 is located on one side of the sound absorbing panel 21 in the width direction. The sound absorbing panel 21 extends into the air outlet frame 1 through the socket 11. The sliding groove 13 located in the width direction limits and guides the sound absorbing panel 21, and the sliding plate 12 will not block the board surface of the sound absorbing panel 21.

[0112] Alternatively, if Figure 8 and Fig. 9 As shown, there are two slide plates 12, and the slide grooves 13 are located on both sides of the sound absorbing board 21 in the width direction, and the side edges of the sound absorbing board in the width direction Y are inserted into the slide grooves 13. Compared with only one slide groove 13, the slide grooves 13 are provided on both sides of the sound absorbing board 21 in the width direction to improve the movement stability of the sound absorbing board 21, the sound absorbing board 21 is evenly stressed, and the installation stability of the sound absorbing board 21 is stronger.

[0113] In some embodiments of the present invention, Figure 7 As shown, the inner wall surface 16 includes a top wall surface 162 and a rear wall surface 161 , and the noise reduction component 2 includes a first sound absorbing panel 21 a and a second sound absorbing panel 21 b , the first sound absorbing panel 21 a is arranged close to the rear wall surface 161 , and the second sound absorbing panel 21 b is arranged close to the top wall surface 162 .

[0114] In some embodiments of the present invention, Fig. 9 As shown, the noise reduction component 2 includes a first sound absorbing board 21a, and the noise reduction component 2 also includes a mounting member 22 connected to the sound absorbing board 21, and the mounting member 22 includes a first plugging plate 22a connected to the first sound absorbing board 21a.

[0115] like Figure 10-12As shown, the socket 11 corresponding to the first sound absorbing panel 21a is the first socket 11a, and the first plug plate 22a is connected to the first socket 11a. The first plug plate 22a is connected to the first sound absorbing panel 21a. When the first sound absorbing panel 21a is installed in the air outlet frame 1, the first plug plate 22a blocks the first socket 11a. The first plug plate 22a cooperates with the air outlet frame 1 to limit the first sound absorbing panel 21a, thereby improving the installation stability and working reliability of the first sound absorbing panel 21a. In addition, the first plug plate 22a blocks the first socket 11a connected to the air outlet duct 10, thereby preventing the airflow in the air outlet duct 10 from flowing out of the air outlet frame 1 through the first plug plate 11a, so that the airflow flows stably along the air outlet duct 10, and the air outlet effect of the air outlet frame component 100 is ensured.

[0116] like Figure 10-12 As shown, the first plug plate 22a is snap-connected with the inner wall of the first socket 11a, a first snap-fitting member 221 is provided on the first plug plate 22a, and a second snap-fitting member 111 is provided on the inner wall of the first socket 11a, and the first snap-fitting member 221 and the second snap-fitting member 111 snap-fit ​​together to connect the first plug plate 22a with the air outlet frame 1. Through the snap-fitting connection, the installation stability and working reliability of the first sound-absorbing plate 21a are better, and the first sound-absorbing plate 21a can be conveniently disassembled, assembled and replaced, and the first sound-absorbing plate 21a can be cleaned or replaced in time, further improving the working reliability of the air outlet frame component 100.

[0117] In some embodiments of the present invention, there are multiple first fasteners 221, and there are multiple second fasteners 111 that correspond to the first fasteners 221 one by one. The first sound absorbing board 21a is evenly stressed, which further improves the installation stability and working reliability of the first sound absorbing board 21a. The number and arrangement positions of the first fasteners 221 can be selected according to actual needs.

[0118] In some embodiments of the present invention, Fig. 9 As shown, the first sound absorbing panel 21a is arranged close to the rear wall surface 161, the first socket 11a is arranged on the top wall surface 162 of the air outlet frame 1, the first socket 11a extends in the left-right direction, the width direction of the first sound absorbing panel 21a is consistent with the left-right direction, the length direction of the first sound absorbing panel 21a is consistent with the up-down direction, and the first sound absorbing panel 21a can be disassembled and assembled with the air outlet frame 1 through the first socket 11a in the up-down direction.

[0119] It is worth noting that the directions here are described with reference to the coordinate system shown in the figure, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the air outlet frame 1 and the sound absorbing panel 21 must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention.

[0120] like Fig.10 and Fig.11As shown, the rearward portion of the top wall surface 162 of the air outlet frame 1 and the rear wall surface 161 form the inner wall of the first socket 11a, and the second fastener 111 is arranged on the inner wall of the first socket 11a. Correspondingly, the first fastener 221 is arranged on the side of the inner wall of the first plugboard 22a facing the first plugboard 11a, and the first fastener 221 and the second fastener 111 are engaged with each other to connect the first plugboard 22a and the air outlet frame 1.

[0121] In some embodiments of the present invention, a second fastener 111 is disposed on both inner walls of the first socket 11a in the width direction. Fig.10 and Fig.11 As shown, the second fastener 111 is provided on the rearward portion of the top wall 162 of the air outlet frame 1 and the rear wall 161, so that the force on the first sound absorbing board 21a is uniform, further improving the installation stability of the first sound absorbing board 21a.

[0122] In some embodiments of the present invention, a plurality of second buckling members 111 are arranged at intervals along the length direction of the inner wall of the first socket 11a. Fig.10 As shown, two second fasteners 111 are spaced apart on the inner wall of one side of the first socket 11a to improve the installation stability of the first plugboard 22a.

[0123] In some specific embodiments of the present invention, Fig.10 As shown, two second fasteners 111 are provided on the rearward portion of the top wall surface 162 of the air outlet frame 1 and on the rear wall surface 161, and the second fasteners 111 located on the same wall are spaced apart in the left-right direction; correspondingly, two first fasteners 221 are provided on both sides of the first plug plate 22a in the width direction, and the two first fasteners 221 located on the same side are spaced apart in the left-right direction, and the first fasteners 221 and the second fasteners 111 are snap-fitted in a one-to-one manner to connect the first plug plate 22a and the air outlet frame 1.

[0124] It is worth noting that the appended Figure 2 -Attached Figure 6 The structure of the sound absorbing panel 21 is described by taking the first sound absorbing panel 21 a disposed on the rear wall surface 161 of the air outlet duct 10 as an example to facilitate understanding of the solutions of the present invention.

[0125] In some embodiments of the present invention, Fig.11 and Fig.12As shown, the slide plate 12 matched with the first sound absorbing plate 21a is the first slide plate 12a, and the slide groove 13 corresponding to the first slide plate 12a is the first slide groove 13a. The first socket 11a is located at the upper end of the first slide groove 13a and is connected to the first slide groove 13a.

Correspondingly, the first guide plate 12a extends in the up-down direction, the first slide groove 13a also extends in the up-down direction, the first sound absorbing board 21a extends into the air outlet frame 1 in the up-down direction, and the first slide groove 13a plays a guiding and limiting role for the first sound absorbing board 21a.

[0127] In some embodiments of the present invention, there are two first sliding plates 12a, and the two first sliding plates 12a are arranged at intervals in the left-right direction. The first sliding grooves 13a are also arranged at intervals in the left-right direction. When the first sound absorbing panel 21a is arranged in the air outlet frame 1, the side edges of the first sound absorbing panel 21a in the left-right direction are inserted into the first sliding grooves 13a to stably limit the first sound absorbing panel 21a in the working position.

[0128] In some embodiments of the present invention, Fig.13 As shown, at least the portion of the first slide groove 13a away from the first insertion opening 11a is a gradual groove 13a1, and at the gradual groove 13a1, the first slide plate 12a and the rear wall surface 161 gradually approach each other in a direction away from the first insertion opening 11a.

[0129] The first sound absorbing panel 21a extends into the first slide groove 13a through the first socket 11a, and the first plug plate 22a is connected to the air outlet frame 1. Therefore, the end of the first sound absorbing panel 21a connected to the first plug plate 22a has strong stability relative to the air outlet frame 1, and the side of the first sound absorbing panel 21a away from the first plug plate 22a extends into the gradient groove 13a1, and the gradient groove 13a1 limits the side of the first sound absorbing panel 21a away from the first plug plate 22a, so that the overall installation stability of the first sound absorbing panel 21a is strong, reducing the shaking of the first sound absorbing panel 21a caused by the impact, thereby reducing the noise generated by the shaking of the first sound absorbing panel 21a.

The socket 11 corresponding to the second sound absorbing board 21b is a second socket 11b, and the second plug plate 22b is blocked on the second socket 11b. The second plug plate 22b can prevent the airflow in the air outlet duct 10 from flowing out of the air outlet frame 1 through the second socket 11b, so that the airflow flows stably along the air outlet duct 10, ensuring the air outlet effect of the air outlet frame component 100.

[0133] In some embodiments of the present invention, Fig. 9 As shown, the second sound absorbing panel 21b is arranged close to the top wall surface 162, and a second socket 11b is opened on the front side of the air outlet frame 1. The second socket 11b extends in the left-right direction. The width direction of the second sound absorbing panel 21b is consistent with the left-right direction, and the length direction of the second sound absorbing panel 21b is consistent with the front-back direction. The second sound absorbing panel 21b can be disassembled and assembled with the air outlet frame 1 through the second socket 11b in the front-back direction.

Fig.12 As shown, the slide groove 13 corresponding to the second slide plate 12b is the second slide groove 13b. The second socket 11b is located at the front end of the second slide groove 13b and is connected to the second slide groove 13b.

The second sound absorbing plate 21b extends into the air outlet frame 1 in the front-to-back direction, and the second slide groove 13b guides and limits the second sound absorbing plate 21b.

[0136] In some embodiments of the present invention, Figure 8 and Fig. 9 As shown, there are two second sliding plates 12b, and the two second sliding plates 12b are spaced apart in the left-right direction. The second sliding grooves 13b are also spaced apart in the left-right direction. When the second sound absorbing panel 21b is arranged in the air outlet frame 1, the side edges of the second sound absorbing panel 21b in the left-right direction are inserted into the second sliding grooves 13b to stably limit the second sound absorbing panel 21b in the working position.

At the same time, the connecting plate 15 can not only improve the structural strength of the air outlet frame 1, but also improve the sealing of the air outlet frame 1, thereby ensuring the air outlet effect of the air outlet duct 10.

[0138] In some embodiments, Fig.12 As shown, a second fastener 111 is provided on the rear wall 161 of the air outlet frame 1 and the connecting plate 15, and a first fastener is provided on the front and rear side surfaces of the first plug plate 22a. The first fastener 221 and the second fastener 111 are snap-fitted together, the force on the first plug plate 22a is uniform, and the first plug plate 22a is stably connected to the air outlet frame 1.

[0139] In some embodiments of the present invention, Fig.12 and Fig.14 As shown, a limiting rib 14 is provided on the top wall surface 162, and the limiting rib 14 and the second sliding plate 12b are limited on two opposite sides of the second sound absorbing plate 21b.

[0140] The second sound absorbing panel 21b extends into the second slide groove 13b through the second socket 11b, so the end of the second sound absorbing panel 21b connected to the second plug plate 22b has strong stability relative to the air outlet frame 1, and the side of the second sound absorbing panel 21b away from the second plug plate 22b extends between the limiting rib 14 and the second slide plate 12b, and the limiting rib 14 limits the second sound absorbing panel 21b, so that the overall installation stability of the second sound absorbing panel 21b is strong, reducing the shaking of the second sound absorbing panel 21b caused by the impact, thereby reducing the noise generated by the shaking of the second sound absorbing panel 21b.

[0141] In some embodiments of the present invention, Fig.12 and Fig.14 As shown, the distance between the limiting rib 14 and the second sliding plate 12b gradually decreases in the direction away from the second socket 11b, and the limiting rib 14 can also play a guiding role, so that the second sound absorbing plate 21b can smoothly and stably extend between the limiting rib 14 and the second sliding plate 12b.

At the same time, the multiple limiting ribs 14 can also improve the structural strength of the air outlet frame 1 and improve the working stability of the air outlet frame component 100.

[0143] In some embodiments of the present invention, Figure 8 As shown, the air outlet duct 10 includes an airflow inlet 10b and an air outlet 10a arranged on the air outlet frame 1. The airflow flows into the air outlet frame 1 through the airflow inlet 10b and flows out from the air outlet 10a through the air outlet frame 1.

[0144] The air outlet frame 1 is provided with two air flow inlets 10b, one of which is located at the bottom wall of the air outlet frame 1, and the other is located at the side wall of the air outlet frame 1. Figure 7 As shown, one airflow inlet 10b is located on the bottom wall of the air outlet frame 1, and the other airflow inlet 10b is located on the front wall of the air outlet frame 1, and the two airflow inlets 10b are connected to each other.

[0145] Correspondingly, the noise reduction component 2 is arranged on the top wall and side wall of the air outlet frame 1 opposite to the airflow inlet 10b, and the noise reduction component 2 is directly opposite to the airflow flow direction, thereby reducing the airflow noise and reducing the working noise of the air outlet frame component 100.

[0146] like Fig. 9As shown, the noise reduction component 2 includes a first sound absorbing panel 21a and a second sound absorbing panel 21b. The first sound absorbing panel 21a is arranged on the rear wall surface 161 of the air outlet frame 1, and the first sound absorbing panel 21a is opposite to the air flow inlet 10b located on the front wall of the air outlet frame 1; the second sound absorbing panel 21b is arranged on the top wall surface 162 of the air outlet frame 1, and the second sound absorbing panel 21b is opposite to the air flow inlet 10b located on the bottom wall of the air outlet frame 1.

Figure 8 As shown, the two air outlets 10a are respectively arranged on the left wall and the right wall of the air outlet frame 1.

[0148] The air outlet frame 1 of the embodiment of the present invention takes in air from the front lower part, changes the airflow direction through the air outlet frame 1, and discharges air in the left and right directions. By arranging the noise reduction components 2 on the top wall and the rear wall, the noise generated by the airflow entering the air outlet frame 1 and impacting the air outlet frame 1 can be reduced, the working noise of the air outlet frame component 100 can be reduced, and the use comfort can be improved.

[0149] The air conditioner 1000 according to the second aspect of the present invention will be described below with reference to the drawings.

When the second sound absorbing plate 21b is installed in the air outlet frame 1, the second plug-in plate 22b is blocked on the second plug-in plate 11b. The humidification component 600 and the air outlet frame component 100 are installed with each other, and the humidification component 610 stops on the second plug-in plate 22b, thereby limiting the second sound absorbing plate 21b and further improving the installation stability of the second sound absorbing plate 21b.

[0158] In some embodiments, the air inlet end of the fan component 500 is connected to the outdoor side, and the outdoor fresh air first flows through the humidification component 600 for humidification before flowing into the air outlet duct 10. The fan component 500 introduces the outdoor fresh air into the room, thereby improving the freshness of the indoor air. The air conditioner 1000 has a fresh air function, which improves the user's comfort. The outdoor fresh air flows into the air outlet frame component 100 after passing through the humidification component 600, so that the air flow has a higher humidity and increases the indoor humidity.

[0159] In some embodiments, the air outlet frame 1 has an air inlet 10b at the bottom and the front side opposite to the rear wall 161, and the air outlet end of the fan component 500 is arranged along the air inlet 10b which is vertically opened upward and faces the bottom.
