In the above scheme, the size of the volute enclosure is increased and the number of fan units 3 is increased by setting the volute enclosure as a spliced ​​structure and providing a plurality of fan units 3 in the housing 1, thereby increasing the air output of the housing 1, so as to solve the problem of low air output of the housing 1 due to limited installation space.

[0042] It should be noted that the volute side panels 2 and the spliced ​​volute 4 form a volute enclosure, and the volute enclosure and the fan part 3 constitute at least part of the fan structure, increasing the volume of the air duct 21 in the volute enclosure, that is, increasing the volume of the fan, thereby increasing the air output of the fan and even the electrical appliances on the ceiling.

[0043] It can be understood that the movably connected spliced ​​volute 4 and the shell 1 includes at least the following two situations. The first situation is that the spliced ​​volute 4 and the shell 1 are detachably connected, that is, when the spliced ​​volute 4 is in the avoidance position, the spliced ​​volute 4 and the shell 1 are in a separated state; the second situation is that the spliced ​​volute 4 and the shell 1 are hingedly or slidingly connected, that is, when the spliced ​​volute 4 is in the avoidance position, the spliced ​​volute 4 is received into the interior of the shell 1.

[0044] In an exemplary embodiment of the present application, the housing 1 is provided with a plurality of air outlets 11, which are arranged in a one-to-one correspondence with a plurality of air ducts 21, and each air outlet 11 is connected to the corresponding air duct 21.

Placing the spliced ​​volutes 4 on different sides of the housing reserves sufficient operating space for the installation of the spliced ​​volutes 4 during the installation process, facilitating the installation operation.

[0048] In another exemplary embodiment of the present application, the air outlet sides of the multiple volute side plates 2 are arranged corresponding to each other, so that the multiple air ducts 21 are arranged in communication with each other.

[0049] Furthermore, if Figure 3 、 Figure 5 As shown, the housing 1 is provided with an air outlet 11, which is connected to each air duct 21. The air outlet 11 is arranged close to the air outlet side of the first volute side plate 23 and the air outlet side of the second volute side plate 24 to allow the air in the air duct 21 to flow out quickly.

[0050] Furthermore, the multiple volute side plates 2 include a first volute side plate 23 and a second volute side plate 24.

The multiple volute side plates 2 are provided to form multiple air ducts, and the multiple fan units 3 are further provided. By providing the multiple fan units 3 within the housing 1, the air output of the housing 1 is increased.

[0051] Specifically, if Figure 4 、 Figure 5As shown, the first volute side plate 23 and the second volute side plate 24 are mirror-imaged along the length direction of the shell 1 so that the opening 22 of the first volute side plate 23 and the opening 22 of the second volute side plate 24 are located on the same side of the shell 1, that is, the two spliced ​​volutes 4 connected to the shell 1 are located on the same side of the shell 1.

[0052] Furthermore, the plurality of volute side panels 2 include a first volute side panel 23 and a second volute side panel 24.

The two openings 22 are spaced apart along the length direction of the housing 1, and the two openings 22 are spaced apart along the width direction of the housing 1. That is, the spliced ​​volutes 4 are arranged on different sides of the housing. During the installation process, sufficient operating space is reserved for the installation of the spliced ​​volutes 4, facilitating the installation operation.

[0053] Specifically, if Figure 1 、 Figure 2 、 Figure 3 As shown, the first volute side plate 23 and the second volute side plate 24 are arranged in an S shape in the shell 1, and the opening 22 of the first volute side plate 23 and the opening 22 of the second volute side plate 24 are located on different sides of the shell 1, that is, the two spliced ​​volutes 4 connected to the shell 1 are located on different sides of the shell 1.
