In this embodiment, the air outlet device further includes a fan, and an air outlet of the fan is communicated with both the upper air duct 20 and the lower air duct 30.

In this embodiment, there are two air duct assemblies, and there are two air volume adjusting assemblies 40, and the two air duct assemblies and the two air volume adjusting assemblies 40 are disposed in one-to-one correspondence. Thus, the two air duct assemblies are respectively a first air duct assembly and a second air duct assembly, the first air duct assembly and the second air duct assembly are arranged at intervals along the height direction of the shell 10, and the first air duct assembly is located above the second air duct assembly. The casing 10 is provided with a first air inlet hole 11 and a second air inlet hole 12, the first air inlet hole 11 is communicated with an air inlet of a fan of the first air duct assembly, and the second air inlet hole 12 is communicated with an air inlet of a fan of the second air duct assembly, so that the air inlet amount and the air outlet amount of the air outlet device are increased, and the air outlet efficiency of the air outlet device is improved.

Optionally, there are two mounting holes 15, and the wind deflectors 41 of each air volume adjusting assembly 40 respectively penetrate through the mounting holes 15 and then extend into the lower air ducts 30 of each air duct assembly, so as to adjust the air volume of the upper air outlet 13 and the lower air outlet 14. Specifically, the lower air duct 30 of the first air duct assembly is communicated with the air inlet of the fan of the second air duct assembly, and the upper air duct 20 of the second air duct assembly is communicated with the air inlet of the fan of the first air duct assembly, so that the air inlet volume and the air outlet volume of the first air duct assembly and the second air duct assembly are increased.

Specifically, when the heat exchange system is in the refrigeration mode, the density of the cold air blown out from the upper air outlet 13 is high, and the cold air gradually sinks towards the ground under the influence of gravity, so that the cold air can be uniformly distributed at the upper air outlet 13, and at the moment, the main air outlet is the upper air outlet, so that the upper air outlet 13 has high air volume, and the refrigeration effect is better; on the contrary, when the heat exchange system operates in the heating mode, the density of the hot air blown out from the upper air outlet 13 is low, the hot air can gradually rise, and the indoor air is caused to have a phenomenon that the ground temperature is low due to high altitude temperature, at the moment, the main air outlet is the lower air outlet 14, the lower air outlet 14 needs large air volume, the upper air outlet 13 can output less hot air through the air volume adjusting component 40, even the hot air does not flow out, the air volume of the lower air outlet 14 is increased, and further the waste of the air volume is reduced.

In the present embodiment, the mounting hole 15 extends along the rotation axis or swing axis of the wind deflector 41. Thus, the user or the worker can pull the wind deflector 41 in a direction parallel to the rotation axis or the swing axis of the wind deflector 41 to detach and mount the wind deflector 41, thereby reducing the difficulty in detaching and mounting the wind deflector 41.

Specifically, the mounting hole 15 is located on the side of the casing 10, and when the wind deflector 41 needs to be detached, the air volume adjusting assembly 40 is simply pulled out from the side.

As shown in fig. 1, 2, and 4-8, the housing 10 includes a volute 16 and a volute cover 17. The volute 16 has an opening, a mounting recess 161 and a first through hole 162, the mounting recess 161 and the first through hole 162 are both communicated with the opening, and the mounting recess 161 is used for being in limit fit with the wind deflector 41. The volute cover 17 covers the opening and surrounds the volute 16 to form an upper air outlet 13 and a lower air outlet 14, and the volute cover 17 is provided with a second through hole 171. One end of the first through hole 162 penetrates the volute 16 and then communicates with the second through hole 171 to form the mounting hole 15. Therefore, the installation hole 15 is easier and simpler to process, and the processing difficulty is reduced. Meanwhile, the shell 10 is of a detachable structure, so that the air duct assembly is easier and simpler to disassemble and assemble, and the disassembling and assembling difficulty is reduced.

Specifically, one end of the first through hole 162 penetrates through the volute 16 and is communicated with the second through hole 171 to form the mounting hole 15, so that the size of the mounting hole 15 is increased, the wind deflector 41 is easier and simpler to mount and dismount, and the mounting and dismounting difficulty is reduced.

As shown in fig. 1 to 3 and 8, the air volume adjusting unit 40 further includes a mounting structure 42. Wherein, the mounting structure 42 is rotatably connected with the wind deflector 41, and at least part of the mounting structure 42 is positioned in the mounting hole 15 and is in limit fit with the mounting hole 15. In this way, the mounting structure 42 is used for being in limit fit with the mounting hole 15, so as to limit the mounting position of the wind deflector 41, and improve the assembly precision of the air volume adjusting assembly 40 and the housing 10. Meanwhile, when a user or a worker attaches or detaches the wind deflector 41, the user or the worker can operate the wind deflector 41 by directly pushing or pulling the mounting structure 42, so that the user or the worker can operate the wind deflector 41 more easily.

Specifically, when the air volume adjusting assembly 40 is assembled with the housing 10, the wind deflector 41 firstly penetrates through the mounting hole 15 and then extends into the lower air duct 30, at least part of the mounting structure 42 is positioned in the mounting hole 15 and is in limit fit with the mounting hole 15, and then the air volume adjusting assembly 40 is mounted on the housing 10. When the air volume adjusting assembly 40 needs to be detached from the casing 10, the mounting structure 42 is firstly pulled out from the mounting hole 15 until the wind deflector 41 is pulled out from the lower duct 30, and then the air volume adjusting assembly 40 and the casing 10 are detached.

As shown in fig. 3, the wind deflector 41 includes a wind deflector body 411 and two rotation shafts 412 provided on the wind deflector body 411, and the mounting structure 42 includes two mounting plates 421 and a connecting portion 422 provided oppositely. Each mounting plate 421 has a first through hole 4211 for passing the spindle 412. Both ends of the connection portion 422 are connected to the two mounting plates 421, respectively. The mounting concave portion 161 has a second through hole 1611 and a limiting groove 1612, a rotating shaft 412 penetrates through the second through hole 1611, and at least a part of the mounting plate 421 is arranged in the limiting groove 1612 and is in limiting fit with the limiting groove 1612. At least a portion of the connection portion 422 is located within the first through hole 162. Thus, the arrangement makes the wind deflector 41 and the mounting structure 42 easier and simpler to mount and dismount, and reduces the difficulty in mounting and dismounting the wind deflector and the mounting structure. Meanwhile, the driving structure is located outside the housing 10, and the above arrangement ensures that the driving structure can be in driving connection with at least one rotating shaft 412 to drive the wind shield 41 to rotate or swing, so as to adjust the air output of the upper air outlet 13 and the lower air outlet 14.

Specifically, the second through hole 1611 is used for allowing a rotating shaft 412 to pass through, and the limit groove 1612 is used for limiting and stopping at least a part of the mounting plate 421, so as to prevent the mounting plate 421 from shifting or shifting relative to the scroll casing 16 to affect the assembling stability of the air volume adjusting assembly 40 and the housing 10.

Arcuate slot 1612a is adapted to receive at least a portion of mounting plate 421. In this way, during the process of installing wind deflector 41 in lower air duct 30, shaft 412 slides along guide groove 1612b until shaft 412 slides to second through hole 1611 and passes through second through hole 1611, so as to assemble shaft 412 and second through hole 1611. Meanwhile, the structure of the limiting groove 1612 is simpler due to the arrangement, the limiting groove 1612 is easy to process and realize, and the processing difficulty and the processing cost of the limiting groove 1612 are reduced.

Wherein the outer surface of the mounting plate 421 is arranged flush with the volute cover 17. In this way, when the mounting plate 421 of the mounting structure 42 is limited and stopped by the second through hole 171 during the process of assembling the air volume adjusting assembly 40 with the casing 10, the air volume adjusting assembly 40 is assembled with the casing 10 in place. Simultaneously, above-mentioned setting makes the outward appearance of accomplishing the air-out device after the assembly neater, more pleasing to the eye.

Specifically, one of the shafts 412 is exposed outside the housing 10 after passing through the second through hole 1611, and the other shaft 412 extends out of the second through hole 171 and is located outside the housing 10, so that the driving structure is connected to the two shafts 412 in a driving manner.

As shown in fig. 3, the connecting portion 422 includes a first plate segment 4221 and a second plate segment 4222 connected to each other, two ends of the first plate segment 4221 and the second plate segment 4222 are connected to the two mounting plates 421 respectively, the first plate segment 4221 and the second plate segment 4222 are arranged at a first preset included angle, the second plate segment 4222 is arranged towards the hole wall of the first through hole 162, and the first plate segment 4221 is arranged flush with the side wall of the scroll casing 16.

Simultaneously, above-mentioned setting makes the outward appearance of accomplishing the air-out device after the assembly neater, more pleasing to the eye.

It should be noted that the sidewall of the volute 16 refers to the outer sidewall of the volute 16, i.e., the outer surface of the sidewall of the volute 16 away from the air duct assembly is flush with the outer surface of the first plate segment 4221 away from the second plate segment 4222.

As shown in fig. 5, the hole wall of the second through hole 171 includes a first wall surface 1711 and a second wall surface 1712 connected to each other, and the first wall surface 1711 and the second wall surface 1712 are disposed at a second predetermined included angle. The connecting portion 422 further includes a third plate segment 4224, the third plate segment 4224 is connected to the first plate segment 4221 through a second plate segment 4222, the second plate segment 4222 is disposed toward the first wall surface 1711, and the third plate segment 4224 is configured to limit the stop with the second wall surface 1712. Optionally, the second predetermined included angle is 90 °. In this way, in the process of attaching and detaching air volume adjusting unit 40 to and from casing 10, the above arrangement can prevent interference of movement between connecting portion 422 and first wall surface 1711 from affecting the attachment of air volume adjusting unit 40 to casing 10. Meanwhile, when the third plate segment 4224 and the second wall surface 1712 are limited and stopped, a user or a worker can obtain that the air volume adjusting assembly 40 and the housing 10 are assembled in place.

As shown in fig. 3, the connecting portion 422 further includes an arc-shaped plate segment 4223, the arc-shaped plate segment 4223 is connected with the second plate segment 4222 through a third plate segment 4224, and a side of the arc-shaped plate segment 4223 facing the wind deflector 41 is used for being attached to the wind deflector 41 to prevent air from passing through. Wherein, two ends of the arc-shaped plate segment 4223 extend to the two mounting plates 421 respectively. Therefore, the sealing performance between the wind shield 41 and the lower air duct 30 is improved, and the influence on the air outlet efficiency of the air outlet device caused by air leakage at the joint of the wind shield 41 and the mounting structure 42 is avoided.

As shown in fig. 5, the hole wall of the second through hole 171 includes an arc-shaped wall surface 1713, the arc-shaped wall surface 1713 is connected to the first wall surface 1711 through a second wall surface 1712, the outer peripheral surface of the mounting plate 421 further includes an arc-shaped surface 4213, and the arc-shaped surface 4213 is in limit stop with the arc-shaped wall surface 1713.
