[0039] Combination Figures 1 to 5 As shown, according to a specific embodiment of the present invention, a housing assembly is provided.

[0040] Specifically, such as Figure 1 As shown, the housing assembly includes a housing 1 and a splicing volute 2. The housing 1 includes an air duct structure 11, which includes an air duct side plate 12 with an opening 14. The splicing volute 2 is movably connected to the housing 1 so that the splicing volute 2 has a blocking position that blocks the opening 14 and a clearance position that moves toward the inside of the opening 14. When the splicing volute 2 is in the blocking position, at least a portion of the splicing volute 2 protrudes out of the outside of the opening 14.

[0041] In this embodiment, the spliced volute 2 is added at the opening 14 of the shell 1, and at least part of the spliced volute is arranged outside the opening, so that the spliced volute 2 can increase the capacity of the air duct structure 11, thereby increasing the air volume. By arranging the spliced volute 2 and the shell 1 in a movable connection, the spliced volute 2 has a blocking position for blocking the opening 14 and an avoiding position for avoiding the opening 14. When the spliced volute 2 is in the blocking position, the spliced volute 2 increases the capacity of the air duct structure 11, thereby increasing the air volume. When the spliced volute 2 is in the avoiding position, the spliced volute 2 saves the longitudinal space of the shell assembly as a whole. By switching the spliced volute 2 between the avoiding position and the blocking position, the flexibility of the shell assembly installation is improved.

[0042] It should be noted that the shell 1 is provided with an air outlet channel 13 arranged downstream of the air duct structure 11. When the spliced volute 2 is in the avoiding position, at least part of the spliced volute 2 is located in the air outlet channel 13. When the spliced volute 2 is in the blocking position, the spliced volute 2 can be connected to the shell 1 or the air duct side plate 12.

[0043] In an embodiment of the present application, the air duct structure 11 further includes an air duct top plate and an air duct bottom plate. The air duct side plate 12, the air duct top plate, and the air duct bottom plate surround the shell 1, that is, the air duct structure 11 belongs to part of the shell 1, and the air duct bottom plate is formed by the bottom of the shell 1. The profile of the air duct side plate 12 can be a volute profile, and the profile of the air duct side plate 12 can also be a profile structure including a straight line profile and an arc line profile.

[0044] In another embodiment of the present application, the air duct structure 11 includes an air duct side plate 12, an air duct top plate, and an air duct bottom plate. The air duct structure 11 is an integral assembly part of the shell 1, that is, the air duct structure 11 belongs to part of the shell 1, and the bottom of the shell 1 forms the air duct bottom plate. Of course, the air duct structure 11 can also be independently formed in the shell 1. At this time, the air duct bottom plate of the air duct structure 11 is connected to the bottom of the shell 1. In this embodiment, the difference from the above-mentioned embodiment is that the air duct structure 11 and the shell 1 each have their own bottom plate.

[0045] In order to reduce the space required for installation of the shell assembly, the spliced volute 2 is arranged to be located in the avoiding position when the spliced volute 2 is located in the interior of the shell 1.

[0046] As shown in Figure 5 The air outlet of the shell 1 is located on one side of the shell 1, and the opening 14 is located on the other side of the shell 1. When the spliced volute 2 is in the avoiding position, the spliced volute 2 is moved to the side of the shell 1 close to the air outlet. This arrangement makes full use of the internal space of the shell 1, avoids occupying additional space outside the shell 1, and improves the space utilization rate.

[0047] Further, the shell assembly further comprises a guide assembly 4. The guide assembly 4 is connected with the shell 1, and the spliced volute 2 is movably connected with the guide assembly 4. The spliced volute 2 moves to the blocking position and the avoiding position through the guide assembly 4.

[0048] In combination Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown in the drawings, by movably connecting the guide assembly 4 with the spliced volute 2, the flexibility and convenience of the movement of the spliced volute 2 are improved, and the movement range of the spliced volute 2 is further limited, so that the movement of the spliced volute 2 is controlled, and the spliced volute 2 is more stable during sliding, and when moving to the blocking position, the spliced volute 2 can be accurately overlapped and sealed with the air duct side plate 12.

[0049] Specifically, the guide assembly 4 comprises a first guide piece 41 and a second guide piece 42. The first guide piece 41 is arranged at the opening 14. One end of the second guide piece 42 is connected with the first guide piece 41 and is arranged at an angle, and the other end of the second guide piece 42 extends into the shell 1 and is arranged towards one side of the air outlet. When the spliced volute 2 is located at the blocking position, the spliced volute 2 is slidably connected with the first guide piece 41, and when the spliced volute 2 is located at the avoiding position, the spliced volute 2 is slidably connected with the second guide piece 42.

[0050] In combination Figure 2 , Figure 4 , Figure 5 As shown in the drawings, the first guide piece 41 provides an installation position when the spliced volute 2 is in the blocking position, and the second guide piece 42 provides an installation position when the spliced volute 2 is in the avoiding position. The arrangement position of the second guide piece 42 also makes the spliced volute 2 in the avoiding position located inside the shell 1, thereby saving the installation space of the shell assembly and improving the space utilization.

[0051] In order to increase the air volume, the spliced volute 2 has a wind guide groove 3 recessed towards the outside of the shell 1. When the spliced volute 2 is in the blocking position, the wind guide groove 3 is arranged at the first guide piece 41, and when the spliced volute 2 is in the avoiding position, the wind guide groove 3 is arranged at the second guide piece 42. When the spliced volute 2 is in the blocking position, the wind guide groove 3 is used to increase the flow area of the air duct structure 11, thereby increasing the air volume.

[0052] Further, the spliced volute 2 comprises a spliced body 21. The spliced body 21 has the wind guide groove 3 and a sliding block 22. One end of the sliding block 22 is connected to one side of the spliced body 21 towards the air outlet, and the other end of the sliding block 22 is slidably arranged on the first guide piece 41 and the second guide piece 42. The spliced body 21 is matched with the first guide piece 41 and the second guide piece 42 through the sliding block 22, so as to switch the spliced body 21 between the avoiding position and the blocking position.

[0053] In combination Figure 2 As shown, the slider 22 drives the spliced body 21 to switch between the avoiding position and the blocking position through cooperation with the first guide 41 and the second guide 42. When the shell assembly is in the working state, the spliced body 21 is located at the blocking position, and the slider 22 is located on the first guide 41. When the shell assembly is in the non-working state, the spliced body 21 is located at the avoiding position, and the slider 22 is located on the second guide 42. This arrangement provides convenience for switching the position of the spliced body 21.

[0054] In this embodiment, the slider 22 is provided in two, and in other embodiments, the number of sliders 22 is not limited to this, but can also be three, four, etc.

[0055] As shown in Figure 4 , Figure 5 As shown, one of the guide assembly 4 and the slider 22 is provided with a guide groove 411, and the other is provided with a connecting protrusion matched with the guide groove 411.

[0056] In this embodiment, the first guide 41 and the second guide 42 are guide rails, which are provided with guide grooves 411, and the connecting protrusions of the slider 22 are embedded in the guide grooves 411. The connecting protrusions are arranged to reciprocally move in the guide grooves 411 to drive the spliced body 21 to be switchably arranged at the avoiding position and the blocking position.

[0057] Among them, the shape of the first guide 41 and the second guide 42 is not limited to this, and the shape of the corresponding slider 22 is also not limited to this. In other embodiments, the first guide 41 and the second guide 42 can be provided with protruding blocks, and the corresponding slider 22 is provided with grooves to realize the matching of the first guide 41, the second guide 42 and the slider 22.

[0058] Specifically, when the spliced volute 2 is in the blocking position, the connecting protrusion of the slider 22 is located in the guide groove 411 of the first guide 41. When the spliced volute 2 is in the avoiding position, the connecting protrusion of the slider 22 is located in the guide groove 411 of the second guide 42. This arrangement makes the guide groove 411 have a limiting effect on the connecting protrusion, ensuring the structural stability of the spliced volute 2 when moving position.

[0059] As shown in Figure 3As shown, the spliced body 21 comprises: an outer plate 211, which is an arc-shaped plate structure; at least two side plates 212, which are arranged at both ends of the outer plate 211 along the width direction of the outer plate 211 and are oppositely arranged, and at least one side plate 212 is connected with the sliding block 22, and the side plate 212 and the outer plate 211 surround to form the air guide groove 3. By surrounding the air guide groove 3 formed by the two side plates 212 and the outer plate 211, the path of the airflow is optimized, the air volume is increased, and the efficiency of air flow is improved.

[0060] The outer plate 211 and the side plate 212 are integrally formed. In this way, the overall performance and quality of the spliced body 21 can be improved, and the production cost can be reduced.

[0061] In other embodiments, the connection mode between the outer plate 211 and the side plate 212 is not limited to this, but can also be welded, bonded, etc.

The spliced volute 2 is movably connected with the shell 1, so that the spliced volute 2 has a blocking position for blocking the opening 14, and the spliced volute 2 has a avoiding position for moving towards the inside of the opening 14; wherein, when the spliced volute 2 is in the blocking position, at least part of the spliced volute 2 is arranged outside the opening 14.

[0063] By increasing the spliced volute 2 at the opening 14 of the shell 1, and arranging at least part of the spliced volute outside the opening, the spliced volute 2 can increase the capacity of the duct structure 11, thereby increasing the air volume. By movably connecting the spliced volute 2 with the shell 1, the spliced volute 2 has a blocking position for blocking the opening 14 and an avoiding position for avoiding the opening 14. The spliced volute 2 in the blocking position increases the capacity of the duct structure 11, thereby increasing the air volume. The spliced volute 2 in the avoiding position saves the longitudinal space of the shell assembly as a whole. By switching the spliced volute 2 between the avoiding position and the blocking position, the flexibility of the installation of the shell assembly is improved.
