[0050] The application will be described below in conjunction with the drawings and specific embodiments:

[0051] The whole air conditioner 10 is installed in the ceiling structure 20 (as shown in Figure 1 The air outlet 113 and the air inlet 114 are communicated with the air outlet 22 and the air inlet 23 respectively, and the air in the room enters the accommodating cavity 112 through the air inlet 114 after passing through the air inlet 23, and is blown to the room through the air outlet 113 and the air outlet 22 after heat exchange of the heat exchanger 500.

[0052] In order to make the air after heat exchange blow to the room as soon as possible, the air outlet 113 and the air outlet 22 are basically only separated by a very small distance, so that the air outlet 113 and the air outlet 22 can be basically overlapped, and the air outlet 113 can be considered to be arranged at the air outlet 22, that is, arranged in the region of the air outlet 22.

[0053] The air outlet 23 and the air outlet 22 can be arranged on the same side of the ceiling structure 20, so that the air outlet is arranged on only one side of the whole ceiling structure 20, which can make the appearance of the whole ceiling structure 20 more neat and beautiful.

[0054] It should be noted that the air conditioner 10 includes an indoor unit and an outdoor unit, the indoor unit is installed indoors, and the outdoor unit is installed indoors. The air conditioner 10 is installed in the ceiling structure 20, which means that the indoor unit of the air conditioner 10 is installed in the ceiling, and not all of the indoor unit and the outdoor unit are installed in the ceiling structure 20. This is common knowledge in the art, and therefore will not be described again.

[0055] Please refer to Figure 2 and Figure 3 In some embodiments, the air conditioner 10 includes a shell 100, a heat exchanger 500, and a fan assembly 300. The shell 100 has a receiving cavity 112 and an air outlet 113 communicating with the receiving cavity 112. The fan assembly 300 is arranged along the depth direction Y of the shell 100 and is arranged close to the air outlet 113. The fan assembly 300 has a plurality of air passing openings 301, and each air passing opening 301 has a wind guide surface 302, so that the air outlet of adjacent two air passing openings 301 at least partially overlaps.

[0056] The shell 100 is the main body of the entire air conditioner 10, and provides a mounting base for other components of the air conditioner 10. The other components of the air conditioner 10 are mounted in the receiving cavity 112 of the shell 100. The shell 100 can protect the other components of the air conditioner 10, reduce the risk of external impurities entering the receiving cavity 112, and protect the internal structures. Placing all other components in the shell 100 can form a whole air conditioner 10, which can facilitate the installation and transportation of the air conditioner 10.

[0057] The shell 100 is generally rectangular. For ease of description, the height direction Z, the width direction X and the depth direction Y of the shell 100 are defined. The height direction Z is the vertical direction of the air conditioner 10 in the installed state. The width direction X is the direction of the longest side of the shell 100. The depth direction Y is perpendicular to the height direction Z and the width direction X.

[0058] The shell 100 also has an air inlet 114 arranged on the side opposite to the air outlet 113. The air inlet 114 and the air outlet 113 are arranged in the depth direction Y of the shell 100. For ease of description, the orientation of the air outlet 113 is defined as front, and the orientation of the air inlet 114 is defined as rear. In the height direction Z of the shell 100, the upper vertical direction is defined as up, and the lower vertical direction is defined as down. In the width direction X, the electronic control assembly 700 is arranged at one end of the shell 100 for electrical connection with the driving assembly 400 to control the operation of the driving assembly 400. The side where the electronic control assembly 700 is arranged is defined as right, and the other side is defined as left.

[0059] The heat exchanger 500 and the fan assembly 300 are arranged in sequence in the depth direction Y of the shell 100, wherein the fan assembly 300 is arranged close to the air outlet 113, and the heat exchanger 500 is arranged close to the air inlet 114. That is, among the heat exchanger 500 and the fan assembly 300, the heat exchanger 500 is arranged closer to the air inlet 114, and the fan assembly 300 is arranged closer to the air outlet 113. After the external air enters the containing cavity 112, it exchanges heat with the heat exchanger 500 first, and then passes through the fan assembly 300 and is blown out from the air outlet 113. The heat exchanger 500 is located on the air suction side of the fan assembly 300, and this arrangement can be considered as a suction type air conditioner.

[0060] Among the heat exchanger 500 and the fan assembly 300, the fan assembly 300 is arranged closer to the air outlet 113, and the air blown out from the fan assembly 300 can be directly blown to the indoor environment through the air outlet 113 without passing through other components, which can reduce the loss of air speed and thus improve the air supply distance of the entire air conditioner 10. In addition, since the air blown out from the fan assembly 300 does not pass through the heat exchanger 500, the static pressure resistance of the entire air conditioner 10 can also be improved.

[0061] Since the fan assembly 300 is arranged closer to the air outlet 113, the air blown out from the air passage 301 can be directly blown out through the air outlet 113. Since the plurality of air passages 301 are arranged at intervals, there is a certain distance between the adjacent two air passages 301, and the air blown out from the air passage 301 is directly blown out from the air outlet 113, which can cause the problem of wind volume blind area at the air outlet 113. The air guide surface 302 arranged at the air passage 301 can make the air blown out from the air passage 301 flow in the direction of the adjacent air passage 301, so that the air blown out from the adjacent two air passages 301 can overlap, and thus the air blown out from the entire air outlet 113 basically does not have a blind area, that is, there is basically no area without air on the entire air outlet 113, so that the air outlet surface of the entire air outlet 113 is continuous air outlet, and the air volume perceived by the user is also continuous, thereby improving the user experience.

[0062] In some embodiments, among the adjacent two air passages 301, the air guide surface 302 of one air passage 301 is arranged inclined toward the direction of the other air passage 301.

[0063] Two air passing openings 301 are arranged at intervals, and the air guide surface 302 of each air passing opening 301 is arranged obliquely, so that the air blown out of the air passing opening 301 can flow along the air guide surface 302 towards the direction of the other air passing opening 301, so that the air blown out by the two adjacent air passing openings 301 can flow towards each other, and then the gap between the two adjacent air passing openings 301 has air overlapping, so that the air volume of the entire air outlet 113 is continuous, and the air volume perceived by the user is also continuous, thereby improving the user experience.

[0064] It should be noted that for a single air passing opening 301, the air guide surface 302 is arranged obliquely, so that the air blown out of the air passing opening 301 can be blown out to the adjacent air passing opening 301, that is, part of the air can be blown out to the left front or right front, and part of the air can be blown out to the front.

[0065] Please refer to Figure 4 Since the air guide surfaces 302 of the two adjacent air passing openings 301 are different in the oblique direction of the other two adjacent air guide surfaces 302, for the convenience of description, four air passing openings 301 are taken as an example for description, and the first air passing opening 301a, the second air passing opening 301b, the third air passing opening 301c and the fourth air passing opening 301d are arranged in sequence from left to right along the width direction X of the shell 100. Each air passing opening 301 has two air guide surfaces 302, and the two air guide surfaces 302 are located on the two sides of the air passing opening 301 along the width direction X of the shell 100. For example, the air guide surface 302 on the left side is defined as the first air guide surface 302a, and the air guide surface 302 on the right side is defined as the second air guide surface 302b.

[0066] The second air guide surface 302b of the first air passing opening 301a is arranged adjacent to the first air guide surface 302a of the second air passing opening 301b, and the second air guide surface 356 of the first air passing opening 301a is arranged obliquely to the right, and the first air guide surface 302a of the second air passing opening 301b is arranged obliquely to the left. Similarly, the second air passing opening 301b is adjacent to the third air passing opening 301c, the second air guide surface 302b of the second air passing opening 301b is arranged obliquely to the right, and the first air guide surface 302a of the third air passing opening 301c is arranged obliquely to the left.

[0067] Please refer to Figure 5That is, the first air guide surface 302a of different wind wheels 310 is all inclined to the left, and the second air guide surface 302b is all inclined to the right. The inclination directions of the two air guide surfaces 302 of the same wind wheel 310 are different, the first air guide surface 302a is inclined to the left, and the second air guide surface 302b is inclined to the right, so that the air passage 301 is roughly in a horn shape. Since the entire fan assembly 300 is arranged close to the air outlet 113, in order to enable the indoor air to circulate, the fan assembly 300 needs to be operated at a relatively large power, and the air passage 301 is roughly in a horn shape, which can diffuse the situation of air blowing out of the air passage 301, slow down the wind speed, avoid the wind speed blowing out of the air outlet 113 being too large to produce a large noise. It can also as much as possible avoid the large wind speed directly blowing on the user, as much as possible to make the user feel the breeze, which can improve the user experience.

[0068] The two air guide surfaces 302 of the same air passage 301 are all inclined (the first air guide surface 302a of the same air passage 301 is inclined to the left, and the second air guide surface 302b is inclined to the right), so that the air passage 301 is roughly in a horn shape. The air passage 301 is roughly in a horn shape, which can make the outer end surface of the air guide surface 302 (the first air guide surface 302a and the second air guide surface 302b) flush with the outer surface of the volute assembly 330, that is, the air passage 301 is an inwardly recessed horn structure.

[0069] Since the entire air conditioner 10 is installed in the ceiling structure 20, in order to enable the ceiling structure 20 to be as small as possible, the distance between the air outlet 113 and the air outlet grille 21 cannot be too far. The air passage 301 is arranged at the air outlet 113, so that the distance between the air passage 301 and the air outlet grille 21 is also very close. The air passage 301 is an inwardly recessed horn structure, which can enable the air guide surface 302 to achieve the air guide function without protruding from the volute assembly 390, without increasing the size of the air conditioner 10 in the depth direction Y, so that the entire air conditioner 10 can be as small as possible. In some embodiments, the inclination angle of the air guide surface 302 is 30°-60°.

[0070] Since each air passage 301 is provided with two air guide surfaces 302, the inclination directions of the two air guide surfaces 302 of the same air passage 301 are different, but the inclination angles of the two air guide surfaces 302 are all 30°-60°. Specifically, the inclination angles of the two air guide surfaces 302 of the same air passage 301 can be the same or different.

[0071] Since the distance between the two adjacent air passing openings 301 is certain, if the inclination angle of the air guide surface 302 is too small, the air volume of the gap between the two adjacent air passing openings 301 will overlap, and there may still be an air volume blind area in the entire air outlet 113. If the inclination angle of the air guide surface 302 is too large, the air guide effect is not good due to the fast wind speed. The inclination angle of the air guide surface 302 is set to 30°-60°, so that the area between the two adjacent air passing openings 301 can not have an air volume blind area as much as possible, and the air outlet effect is improved.

[0072] It is easy to understand that the inclination angle of the air guide surface 302 is related to the distance between the two adjacent air wheels 310. The greater the distance between the two adjacent air wheels 310, the greater the inclination angle of the air guide surface 302.

[0073] Please refer to Figure 6 In some embodiments, the fan assembly 300 includes a volute assembly 390 and a plurality of air wheels 310, the plurality of air wheels 310 are sequentially arranged along the width direction X of the shell 100, and a plurality of air passing openings 301 are arranged in the volute assembly 390 and correspond to the plurality of air wheels 310. Along the width direction X of the shell 100, the width of the air wheel 310 is adapted to the width of the air passing opening 301, so that the radial air outlet of the air wheel 310 can be blown out from the air passing opening 301, which can reduce the loss of air volume and improve the working effect of the air conditioner 10.

[0074] In some embodiments, the distance between the two adjacent air wheels 310 is 110mm-140mm.

[0075] The air wheel 310 is a centrifugal air wheel 310, which is an axial air inlet and a radial air outlet. If the distance between the two adjacent air wheels 310 is close, the air inlet of the two adjacent air wheels 310 will be affected, and the two adjacent air wheels 310 will compete for air. If the distance between the two adjacent air wheels is far, the size of the entire air conditioner 10 along the width direction X of the shell 100 will be long, which will result in a large size of the entire air conditioner 10. The distance between the two adjacent air wheels 310 is 110mm-140mm, which can meet the air inlet of the air wheel 310 and can make the entire air conditioner 10 as small as possible.

[0076] In some embodiments, the air conditioner 10 further comprises a driving assembly 400, which is arranged between two adjacent wind wheels 310 and is in driving connection with the plurality of wind wheels 310; the interval distance between the two adjacent wind wheels 310 of the driving assembly 400 is 210mm-240mm. Since the driving assembly 400 is relatively large, if the driving assembly 400 is arranged between the two adjacent wind wheels 310, the interval distance between the two wind wheels 310 can be slightly larger, which can be 210mm-240mm, and the inclination angle of the air guide surface 302 of the air passing opening 301 of the wind wheel 310 can be set relatively larger, so that the front of the driving assembly 400 does not appear a wind volume blind area as much as possible.

[0077] In some embodiments, the volute assembly 390 comprises a volute cover assembly 320 and a volute body assembly 330, the volute body assembly 330 and the volute cover assembly 320 are detachably connected to form a plurality of air cavities 394, the volute cover assembly 320 is located at the air outlet 113, and a plurality of air passing openings 301 are arranged on the volute cover assembly 320.

[0078] Among them, the volute cover assembly 320 is located at the air outlet 113, that is, the entire fan assembly 300 is arranged closer to the air outlet 113, since the fan assembly 300 is arranged closer to the air outlet 113, if the fan assembly 300 needs to be replaced or repaired, the entire fan assembly 300 can be directly repaired from the air outlet 113, which is simple and convenient to operate, without the need to set up a separate repair opening.

[0079] The volute cover assembly 320 and the volute body assembly 330 are detachably connected, and the volute cover assembly 320 is located at the air outlet 113, if the wind wheel 310 needs to be repaired or replaced, the volute cover assembly 320 can be detached from the volute body assembly 330, so that the wind wheel 310 can be exposed from the air outlet 113, and the wind wheel 310 can be directly repaired through the air outlet 113, without damaging the original suspended ceiling structure 20, which can reduce the repair difficulty of the fan assembly 300, and facilitate the replacement and repair of the fan assembly 300.

[0080] The volute cover assembly 320 is detachably connected with the volute body assembly 330 to form the air cavity 394 capable of mounting the wind wheel 310. The wind wheel 310 is mounted in the air cavity 394. The volute body assembly 330 is fixedly mounted on the shell 100. The volute cover assembly 320 is detachably connected with the volute body assembly 330. The volute cover assembly 320 can be detachably connected with the shell 100 and the volute body assembly 330, or can be detachably connected with only the volute body assembly 330 and not connected with the shell 100. When the fan assembly 300 needs to be overhauled, the connection between the volute cover assembly 320 and the volute body assembly 330 is released, so that the volute cover assembly 320 is detached from the containing cavity 112, while the volute body assembly 330 is still fixed in the containing cavity 112. After the volute cover assembly 320 is detached, the wind wheel 310 can be exposed from the air outlet 113 and can be directly overhauled from the air outlet 113.

[0081] Specifically, since the entire air conditioner 10 is installed in the ceiling, the ceiling has the air outlet 22 and the air inlet 23. The air outlet 22 is in communication with the air outlet 113, and the air inlet 23 is in communication with the air inlet 114. The air outlet 22 and the air inlet 23 are both provided with grilles. When the fan assembly 300 needs to be overhauled, the grilles at the air outlet 22 are first detached, so that the air outlet 113 of the entire air conditioner 10 is exposed from the air outlet 22. Since the volute cover assembly 320 is arranged at the air outlet 113, the connection between the volute cover assembly 320 and the volute body assembly 330 is released, so that the volute cover assembly 320 is detached from the containing cavity 112, while the volute body assembly 330 is still fixed in the containing cavity 112. After the volute cover assembly 320 is detached, the wind wheel 310 can be exposed from the air outlet 113 and can be directly overhauled from the air outlet 113.

[0082] Please refer to Figure 7 In some embodiments, the volute cover assembly 320 includes a plurality of volute covers 321, the plurality of volute body assemblies 330 includes a plurality of volute bodies 331, and one volute cover 321 is connected with one volute body 331 to form one air cavity 394. One volute cover 321 and one volute body 331 can form one volute module 396, and one volute module 396 and one wind wheel 310 can form one fan module.

[0083] Since the wind wheel 310 is a centrifugal wind wheel 310, the axial length of the centrifugal wind wheel 310 is small, and the width direction X of the air conditioner 10 is much larger than the axial length of the centrifugal wind wheel 310, so that multiple centrifugal wind wheels 310 can be arranged, each wind wheel 310 is provided with a volute module 396, and the volute cover assembly 320 can include multiple volute covers 321, the volute body assembly 330 can include multiple volute bodies 331, one volute cover 321 and one volute body 331 can form one volute module 396, and the wind wheel 310 can be installed in the volute module 396.

[0092] That is, in the embodiments of the present application, the volute of the fan assembly 300 is three-segmented, which is composed of the first shell segments 341, the second shell segments 351 and the volute covers 321. This way can facilitate the assembly of the entire fan assembly 300 and facilitate the maintenance of the entire fan assembly 300. Of course, in addition to this, the volute can also be two-segmented, that is, the volute body 331 can be an integral whole. In addition, the volute can also be four-segmented or other forms, which can not be limited.

[0093] As for the connection mode of the first shell segments 341 and the second shell segments 351, it can be clamped or fixedly connected through screws or other fixing members. In some embodiments, the first shell segments 341 are clamped with the second shell segments 351. The following will be described in detail how the first shell segments 341 are clamped with the second shell segments 351.

[0094] Please refer to Figure 10 , Figure 11 and Figure 12 In some embodiments, the first shell segments 341 are provided with first clamping members 342, and the second shell segments 351 are provided with second clamping members 352, the first clamping members 342 are clamped with the second clamping members 352.

[0095] Specifically, the second clamping piece 352 comprises a clamping portion 353, the first clamping piece 342 is provided with a clamping hole 343, and the clamping portion 353 can be clamped with the clamping hole 343. The clamping portion 353 comprises a connecting segment 353a and a clamping segment 353b protruding from the connecting segment 353a, the connecting segment 353a is arranged in the clamping hole 343, and the clamping segment 353b abuts against the clamping hole 343.

[0096] The first clamping piece 342 is further provided with a guide portion 347, the clamping portion 353 can slide relative to the guide portion 347 in the process of assembling the first shell segment 341 and the second shell segment 351, the guide portion 347 can abut against the clamping portion 353, so that the clamping portion 353 can be clamped into the clamping hole 343.

[0097] In addition, of the first clamping piece 342 and the second clamping piece 352, one is provided with a slot 354, and the other is provided with a plug-in portion 344, in the process of assembly, the plug-in portion 344 is arranged in the slot 354, and the cooperation of the two can realize the assembly of the first shell segment 341 and the second shell segment 351, and can seal the gap (air cavity 394) between the first shell segment 341 and the second shell segment 351, thereby reducing the air leakage between the first shell segment 341 and the second shell segment 351.

[0098] Please refer to Figure 13 In some embodiments, the volute cover 321 is provided with a first guide surface 322, the second shell segment 351 is provided with a second guide surface 356, the shapes of the first guide surface 322 and the second guide surface 356 are matched, so that the first guide surface 322 can slide along the second guide surface 356, and the volute cover 321 is assembled to the second shell segment 351.

[0099] The shapes of the first guide surface 322 and the second guide surface 356 are matched, that is, if the first guide surface 322 is a convex surface, the second guide surface 356 is a concave surface. The concave-convex structure can position the volute cover 321. Specifically, if the first guide surface 322 is a concave arc surface, the second guide surface 356 is a convex arc surface. If the first guide surface 322 is an L-shaped concave surface, the second guide surface 356 is an L-shaped convex surface.

[0100] The cooperation of the first guide surface 322 and the second guide surface 356 can play a guiding role, and at the same time, the first guide surface 322 is arranged in the second guide surface 356, which can also play a certain sealing role, thereby reducing the risk of air leakage between the volute body 331 and the volute cover 321.

[0101] The second guide surface 356 is arranged along the air outlet direction of the air conditioner 10, that is, when the volute cover 321 needs to be disassembled, the entire volute cover 321 can be pulled out along the air outlet direction. Since the air inlet 114 and the air outlet 113 are arranged in the depth direction Y of the shell 100, the air outlet direction is consistent with the depth direction Y of the shell 100.

[0102] In some embodiments, at least one of the second guide surface 356 and the first guide surface 322 is arranged obliquely along the depth direction Y of the shell 100. At least one of the second guide surface 356 and the first guide surface 322 arranged obliquely along the depth direction Y of the shell 100 can be that only the second guide surface 356 is arranged obliquely along the depth direction Y of the shell 100, or only the first guide surface 322 is arranged along the depth direction Y of the shell 100, or both the first guide surface 322 and the second guide surface 356 are arranged along the depth direction Y of the shell 100.

[0103] At least one of the second guide surface 356 and the first guide surface 322 arranged obliquely along the depth direction Y of the shell 100 can play a positioning role for the volute cover 321 during the process of disassembling and assembling the volute cover 321, so that the volute cover 321 can slide to the set position as much as possible.

[0104] Among them, the first guide surface 322 and the second guide surface 356 are two respectively, which are arranged on both sides of the axial direction of the fan wheel 310, and are matched with the volute body 331 on both sides of the volute cover 321 during assembly or disassembly, which can improve the stability of the assembly of the volute cover 321 and the volute body 331.

[0105] Please refer to Figure 9 and Figure 13 In some embodiments, the first shell segment 341 is provided with a positioning portion 345, and is arranged close to the air outlet 113. The volute cover 321 is provided with a positioning cover 323, and the positioning cover 323 is covered on the positioning portion 345. When the sliding rail 322 is slid to the position relative to the sliding groove, the positioning cover 323 covered on the positioning portion 345 can play a sealing role for the connection between the first shell segment 341 and the volute cover 321, which can reduce the air leakage.

[0106] In some embodiments, the fan wheel 310 is a plurality of volute covers 321, and the plurality of volute covers 321 are integrally formed into the first cover segment 320a or the second cover segment 320b. Among them, the fan wheel 310 is a centrifugal fan. Since the length in the width direction X of the shell 100 is relatively long, a plurality of fan wheels 310 can be arranged in the containing cavity 112, and the plurality of fan wheels 310 are arranged along the width direction X of the shell 100, which can improve the air flow into the containing cavity 112 and increase the heat exchange effect of the entire air conditioner 10.
