[0025] See also Figures 1 to 4 As shown, according to an embodiment of the present application, the fan mounting structure includes a centrifugal fan 13 and a rear panel 17 arranged on the air inlet side of the centrifugal fan 13, the rear panel 17 is provided with an air inlet, and a guide ring 15 is provided on the side of the rear panel 17 facing the centrifugal fan 13, the guide ring 15 is arranged corresponding to the air inlet, and the upper and lower positions of the guide ring 15 relative to the rear panel 17 are adjustable.

[0026] The fan installation structure designs the guide ring 15 to be adjustable in the upper and lower positions relative to the rear panel 17. Therefore, during the installation process of the impeller or the long-term operation process, if the gap between the impeller of the centrifugal fan 13 and the guide ring 15 changes in the upper and lower directions, resulting in the gap between the impeller of the centrifugal fan 13 and the guide ring 15 being too small or even contacting, the upper and lower positions of the guide ring 15 can be easily adjusted so that the position of the guide ring 15 can always be adapted to the impeller position of the centrifugal fan 13, so that the gap between the impeller of the centrifugal fan 13 and the guide ring 15 is appropriate, thereby protecting the guide ring 15 and ensuring that the centrifugal fan 13 can operate normally.

[0027] In one embodiment, a plurality of waist-shaped holes 18 are provided on the rear panel 17, each waist-shaped hole 18 is vertically arranged, and a threaded connection hole is provided on the guide ring 15. The locking bolt passes through the waist-shaped hole 18 and is connected in the threaded connection hole to fix the guide ring 15 on the rear panel 17. In this embodiment, each connection hole on the rear panel 17 for installing the guide ring 15 is a waist-shaped hole, so that the guide ring 15 can be moved as a whole, that is, can be translated, so that the upper and lower positions of the guide ring 15 can be conveniently adjusted, so that the upper and lower positions of the guide ring 15 are adapted to the impeller position of the centrifugal fan 13, and the gap between the impeller and the guide ring 15 is ensured to be appropriate.

[0028] The waist-shaped hole 18 is vertically arranged here, which means that the length direction of the waist-shaped hole 18 is vertically arranged, so that the locking bolt can move up and down along the waist-shaped hole 18, so as to facilitate the adjustment of the upper and lower positions of the guide ring 15.

[0029] In one embodiment, a sealing gasket 16 is provided between the guide ring 15 and the rear panel 17. The sealing gasket 16 is located between the guide ring 15 and the rear panel 17, and can fill the gap between the guide ring 15 and the rear panel 17, and can play a sealing and vibration reduction role, and can effectively block the waist-shaped hole 18, prevent external impurities or insects from entering the cabinet air conditioner, and effectively protect the internal structure. The sealing gasket 16 is, for example, a sponge.

[0030] In this embodiment, when the guide ring 15 is installed on the rear panel 17, a sponge can be firstly attached around the guide ring 15, and then the guide ring 15 can be fixed on the rear panel 17. The waist-shaped hole 18 provided on the rear panel 17 allows the locking bolt to move up and down along the track of the waist-shaped hole 18, so that the upper and lower gaps between the impeller of the centrifugal fan 13 and the guide ring 15 can be adjusted to the optimal position.

[0031] In one embodiment, the fan mounting structure further includes a fan bracket 11, and the centrifugal fan 13 is mounted on the fan bracket 11. The upper and lower ends of the fan bracket 11 are provided with a rotating pair, and the fan bracket 11 can adjust the swing angle of the centrifugal fan 13 relative to the rear panel 17 through the rotating pair. In this embodiment, the swing angle of the centrifugal fan 13 relative to the rear panel 17 can be adjusted by adjusting the rotation position of the fan bracket 11 on which the centrifugal fan 13 is mounted. This adjustment structure can adjust the gap of the centrifugal fan 13 in the left and right directions relative to the guide ring 15. The adjustment structure cooperates with the waist-shaped hole 18 on the rear panel 17. The waist-shaped hole 18 can be used to adjust the upper and lower positions of the guide ring 15, and the fan bracket 11 can be used to adjust the left and right positions of the centrifugal fan 13, so that the relative positions of the impeller of the centrifugal fan 13 and the guide ring 15 in the upper and lower directions and left and right directions can be adjusted. Therefore, the difficulty of installing the centrifugal fan 13 can be solved, so that the installation position of the centrifugal fan 13 can be quickly matched with the guide ring 15, so that the gaps at various positions of the two can quickly reach the optimal value, so that the difficulty of the installation process can be reduced when installing the rear panel 17, and the production efficiency can be improved.

[0032] In this embodiment, the centrifugal fan 13 is fixed to the fan bracket 11 by screws 9 or other fasteners.

[0033] During the operation of the centrifugal fan 13, once the position of the centrifugal fan 13 changes, the position of the centrifugal fan 13 or the guide ring 15 can be quickly adjusted so that the relative positions of the two continue to match and maintain a good matching relationship, thereby avoiding the centrifugal fan 13 being biased downward due to factors such as gravity and increased bearing clearance due to long-term operation of the fan, and avoiding the problem of the gap between the impeller of the centrifugal fan 13 and the guide ring 15 being too small or even contacting and causing friction.

[0034] In one embodiment, the fan mounting structure further includes a chassis 4, and the bottom end of the fan bracket 11 can be rotatably mounted on the chassis 4. In this embodiment, the fan bracket 11 is vertically mounted on the chassis 4, which can facilitate the installation and fixation of the fan bracket 11, and ensure that the mounting structure of the fan bracket 11 is stable and reliable, and ensure that the mounting structure of the centrifugal fan 13 is stable.

[0035] In one embodiment, the fan installation structure further includes a left side panel 14, a right side panel 1 and a cabinet 2, wherein the left side panel 14 and the right side panel 1 are fixedly mounted on the left and right sides of the chassis 4, and the partition 3 is located in the middle of the cabinet 2 to separate the evaporator and the condenser.

[0036] In one embodiment, the fan bracket 11 has an operating end extending out of the chassis 4, and the operating end is configured to adjust the rotation angle of the fan bracket 11. In this embodiment, the operating end for adjusting the fan bracket 11 extends out of the chassis 4, and the adjusting bolt 10 for adjusting the guide ring 15 is also located on the outside of the rear panel 17, so the position adjustment of the centrifugal fan 13 and the guide ring 15 can be performed outside the cabinet air conditioner. Without disassembling the cabinet, the gap between the guide ring 15 and the impeller can be adjusted externally to avoid affecting the normal operation of the integrated cabinet air conditioner due to the small gap between the two, and the operation is simpler, more convenient and faster. During the installation process, the cabinet air conditioner can also be assembled first, and then the position of the centrifugal fan 13 or the guide ring 15 can be adjusted from the outside according to the gap size between the guide ring 15 and the impeller of the centrifugal fan 13 after installation, so that the gap size between the two is kept at the optimal position, thereby reducing the difficulty of the installation process when the air conditioner is installed on the panel and improving production efficiency.

[0037] In one embodiment, the operating end is provided with a polygonal groove, and the fan mounting structure further comprises an adjuster 12, the adjuster 12 has a protrusion matching the shape of the polygonal groove, and the adjuster 12 can adjust the rotation angle of the fan bracket 11 through the operating end.

[0038] In one embodiment, a handle can also be directly set at the operating end, and the handle is fixedly connected to the protruding end of the fan bracket 11. When the rotation position of the fan bracket 11 needs to be adjusted, the handle can be directly pulled to achieve the operation, which can avoid problems such as loss of the operating part.

[0041] When it is necessary to rotate the fan bracket 11 to adjust the left and right gap between the impeller of the centrifugal fan 13 and the guide ring 15, there is no need to disassemble the cabinet. Just loosen the two adjusting bolts 10 on the chassis 4 and use the regulator 12 to rotate the shaft to a certain angle. When the left and right gap between the impeller of the centrifugal fan 13 and the guide ring 15 is at a suitable position, tighten the two adjusting bolts 10 on the chassis 4 to fix the fan bracket 11 on the chassis 4.

[0042] In one embodiment, the fan installation structure includes a partition 3, a bearing bracket 6 is installed on the partition 3, a bearing seat 7 is provided on the bearing bracket 6, a bearing 8 is installed in the bearing seat 7, and the top end of the fan bracket 11 is installed in the bearing 8.
