Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model belongs. The terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. The term "or/and" as used herein includes any and all combinations of one or more of the associated listed items.

First, referring to fig. 9 to 12, the present utility model provides a noise reduction air duct structure, which at least includes a side plate 221 and an air outlet air duct 102, wherein the side plate 221 is disposed around the periphery of the centrifugal wind wheel, and the periphery of the centrifugal wind wheel is the air outlet part of the centrifugal wind wheel. Specifically, the periphery of the centrifugal wind wheel comprises a plurality of fan blades which are distributed at intervals, the fan blades are distributed around the axis of the centrifugal wind wheel, an air outlet gap is formed between any two adjacent fan blades, and an air inlet end of the centrifugal wind wheel is provided with openings which are communicated with the air outlet gaps; in some embodiments, the air outlet duct 102 includes a blowing duct 103 and a fresh air duct 104 as shown in fig. 2, 4-8.

Referring to fig. 10 and 12, two ends of the side plate 221 are a head end 2211 and a tail end 2212 respectively, an arc-shaped channel is formed between the side plate 221 and the peripheral side of the centrifugal wind wheel, and air flows along the arc-shaped channel after being blown out of the air outlet gap. The arcuate path between the side plate 221 and the centrifugal rotor circumference side increases gradually along the surface of the side plate 221 from the head end 2211 toward the end 2212, so that the distance from the head end 2211 to the rotor axis is smaller than the distance from the end 2212 to the centrifugal rotor axis, and the distance from the head end 2211 to the rotor circumference side is smaller than the distance from the end 2212 to the rotor circumference side.

The space between the head end 2211 and the end 2212 forms an air outlet (the air outlet between the head end 2211 and the end 2212 is referred to as a first air outlet 202 shown in fig. 4-9 and 10-12), the arc-shaped channel is communicated with the air outlet, so that air enters the centrifugal wind wheel through the air inlet end of the centrifugal wind wheel, then flows out of the centrifugal wind wheel from the air outlet gap, and then flows along the arc-shaped channel to the air outlet. As a preferred embodiment, the side plates 221 terminate from the head end 2211 to the end 2212 at an angle of greater than 180 ° around the rotor.

The air outlet duct 102 is communicated with an air outlet and comprises a first air wall 131 and a second air wall 132, one end of the first air wall 131 is connected with the tail end 2212, and the second air wall 132 comprises a first curved wall 1322 and a second curved wall 1323. Referring to fig. 10 to 11, one end of the first curved wall 1322 is connected to the head end 2211, the first curved wall 1322 extends in a curved manner relative to the side plate 221 in a direction away from the centrifugal wind wheel, one end of the second curved wall 1323 is connected to one end of the first curved wall 1322 relatively away from the head end 2211, and the second curved wall 1323 bends relative to the first curved wall 1322 in a direction close to the centrifugal wind wheel and extends to one side of the first curved wall 1322 away from the first wind wall 131.

The noise reduction air duct structure forms the noise reduction volute tongue 23 with the noise reduction function through the first curved wall 1322 and the second curved wall 1323, and the noise reduction volute tongue 23 provides a longer curved extension diversion surface to divert the airflow flowing out of the air outlet. The curved extension drainage faces the inner side part of the airflow beam, namely the part of the airflow beam close to the axis of the centrifugal wind wheel, the first wind wall 131 drains the outer side part of the airflow beam, namely the part of the airflow beam far away from the axis of the centrifugal wind wheel, the flow velocity balance and the pressure balance of the inner side airflow beam and the outer side airflow beam are realized through the drainage function, the friction interference of the noise reduction volute tongue 23 on the airflow is weakened, the flow direction difference degree between the outer side airflow beam and the inner side airflow beam is controlled, and therefore the noise reduction wind channel structure can reduce wind noise when the airflow flows out of the wind outlet.

In some embodiments, the noise reduction air duct structure comprises a volute for installing and accommodating the centrifugal wind wheel, the volute comprises the side plates 221, and further comprises an upper cover plate and a lower cover plate which are respectively positioned at two ends of the centrifugal wind wheel, the side plates 221 and the upper cover plate are integrally connected with the lower cover plate, and optionally, the centrifugal wind wheel is preloaded in the volute. Of course, in other embodiments, the volute does not need to be preloaded with a centrifugal wind wheel, and the noise reduction air duct structure does not need to include a separate volute.

Alternatively, referring to fig. 11, in some embodiments, a first curved wall 1322 is coupled to the head end 2211 and forms a transition radius, and a second curved wall 1323 is coupled to an end of the first curved wall 1322 opposite the head end 2211 and forms a transition radius. Therefore, the inner side of the first curved wall 1322 and the inner side of the second curved wall 1323 form a curved guiding surface with a wavy curved surface, so that the friction force of the curved guiding surface to the airflow can be reduced.

Alternatively, referring to fig. 11, a second curved wall 1323 is connected to a side of the side plate 221 facing away from the centrifugal rotor. Specifically, the second wind wall 132 further includes a second arc wall 1321, the second arc wall 1321 is in smooth transition connection with the second curved wall 1323, the second arc wall 1321 is connected to the side plate 221 in a manner of being circumscribed on one side of the side plate 221 away from the centrifugal wind wheel, and a tangential position of the second arc wall 1321 and the side plate 221 is a connection position of the second curved wall 1323 and the side plate 221.

Optionally, the first air wall 131 includes a first arc-shaped wall 1311, and when the air flows from the head end 2211 along the side plate 221 to the tail end 2212, the air obtains a first rotation speed, and when the air flows from the upstream of the air outlet duct 102 along the first arc-shaped wall 1311 to the downstream of the air outlet duct 102, the air obtains a second rotation speed, and the first rotation speed and the second rotation speed have the same rotation direction. In the embodiments shown in fig. 9 to 10 and 12, the directions of the first rotation speed and the second rotation speed are both counterclockwise rotation directions.

Further, referring to fig. 10 and 12, in some embodiments, the air outlet duct 102 is provided with an external through notch 133, and includes a movable air wall 45 that can be switched between an open state and a closed state. The movable air wall 45 opens the outer through gap 133 in the open state, so that the air outlet of the external fan is communicated with the outer through gap 133, at this time, the air flow driven by the centrifugal wind wheel surrounded by the side plate 221 and the air flow driven by the external fan both flow along the air outlet air duct 102, and the movable air wall 45 closes the outer through gap 133 in the closed state to block the air outlet of the external fan and the air outlet air duct 102, at this time, only the air flow driven by the centrifugal wind wheel surrounded by the side plate 221 flows along the air outlet air duct 102.

For convenience of description, the air flow driven by the centrifugal wind wheel surrounded by the side plate 221 is defined as a first air flow, and the air flow driven by the external fan is defined as a second air flow. In order to control the degree of interference collision between the first air flow and the second air flow, and reduce the kinetic energy loss of the first air flow and the kinetic energy loss of the second air flow, the movable air wall 45 has an arc-shaped plate structure. Referring to fig. 10, when the movable air wall 45 is in the closed state, one end of the movable air wall 45 is in buckling engagement with the first arc-shaped wall 1311, and the other end is in buckling engagement with the second arc-shaped wall 1321.

Specifically, taking fig. 10 as an example, in the process that the first airflow sequentially flows through the first arc-shaped wall 1311, the movable air wall 45 and the second arc-shaped wall 1321 along the air outlet duct 102, the curvature centers of the airflow flow paths are all located at the left side of the airflow, that is, at one side of the inner walls of the first arc-shaped wall 1311, the movable air wall 45 and the second arc-shaped wall 1321, and the inner walls of the first arc-shaped wall 1311, the movable air wall 45 and the second arc-shaped wall 1321 are used to form the inner wall of the air outlet duct 102.

In other embodiments, the outer through gap 133 and the movable air wall 45 may be omitted, and after the outer through gap 133 is omitted, the first arc wall 1311 and the second arc wall 1321 are directly connected in a forward bending manner, so that the curvature center of the airflow track is located on the left side of the airflow, that is, on the inner wall sides of the first arc wall 1311 and the second arc wall 1321, when the first airflow flows through the first arc wall 1311 and the second arc wall 1321 sequentially along the air outlet duct 102.

Next, the present utility model provides an air dispatcher 100, and also provides a bathroom fixture including the air dispatcher 100 of the present utility model. The air dispatching device 100 not only can be used for bathroom equipment to carry out air dispatching transportation for the bathroom, but also can be used for other device equipment and carrying out air dispatching transportation for other occasions. For convenience of description, the following description of the air-dispatching device 100 will take an installation and application scenario of the air-dispatching device 100 in bathroom facilities as an example.

The air dispatching device 100 comprises an air duct chamber 10, wherein the air duct chamber 10 comprises a machine case 11 and a box plate 12 arranged on the machine case 11, the interior of the machine case 11 is hollow and is provided with a cavity which is opened by an opening, and the box plate 12 covers the opening of the cavity and closes the cavity.

It should be noted that, although the outer port 101 has two functions, the outer port 101 does not allow the two functions to be simultaneously performed, in order to prevent the air flowing to the outside and the air flowing to the duct chamber 10 from interfering with each other.

Specifically, the air blowing duct 103 has an air discharge gap 1312 communicating with the outer port 101, and the air discharge gap 1312 has a closed and opened state. When the exhaust notch 1312 is closed, the air blowing duct 103 cannot be communicated with the outer through hole 101 through the exhaust notch 1312, so that the air collecting port 1021 cannot be communicated with the outer through hole 101, but the air blowing duct 103 is normally communicated with the air outlet 1022; when the exhaust notch 1312 is opened, the air blowing duct 103 can communicate with the outer through hole 101 through the exhaust notch 1312, so that the air collecting port 1021 and the outer through hole 101 can communicate with each other.

When the air inlet throat 107 is closed, the air inlet duct 106 is blocked from the outer through hole 101, so that the fresh air duct 104 is blocked from the outer through hole 101, and outdoor air cannot enter the air inlet duct 106 and the fresh air duct 104 through the outer through hole 101; when the air inlet throat 107 is opened, the air inlet duct 106 is communicated with the outer through opening 101, so that a communication state can be formed between the fresh air duct 104 and the outer through opening 101, and outdoor air is allowed to enter the air inlet duct 106 and the fresh air duct 104 through the outer through opening 101, and finally, the outdoor air is discharged indoors from the air outlet 1022.

In a state that the exhaust notch 1312 is opened, the first air outlet 202 is communicated with the outer through hole 101 through the exhaust notch 1312, and indoor air leaving the first fan 20 flows out of the outer through hole 101 through the exhaust notch 1312 and finally flows out of the air, and at this time, the air dispatching device 100 operates an exhaust working condition and performs a ventilation function; in a state that the exhaust notch 1312 is closed, the first air outlet 202 is communicated with the air outlet 1022 through the air blowing duct 103, and the indoor air leaving the first fan 20 flows out of the air outlet 1022 along the air blowing duct 103 to finally return to the indoor, at this time, the air dispatching device 100 operates the circulation working condition and performs the air circulation function.

When the second fan 30 is installed in the air duct chamber 10, the air dispatching device 100 is compatible with three functions, namely, the air dispatching device 100 adopts a functional form of three functions of an air circulation function, a ventilation function and a fresh air function; when the second fan 30 moves out of the air duct chamber 10, the air dispatching device 100 has two functions, namely, the air dispatching device 100 adopts a functional form of combining an air circulation function and a ventilation function.

When the air door 41 is in the first position, the air dispatching device 100 can operate the air exhaust working condition and perform the ventilation function, and meanwhile, the second door plate 412 limits the outdoor air to enter the air inlet duct 106 through the outer through hole 101; when the air door 41 is in the second position, the air dispatching device 100 can operate the circulation working condition and execute the airflow circulation function, can also operate the fresh air working condition and execute the fresh air function, and can also operate the circulation working condition and the fresh air working condition simultaneously.

For simplicity of description, when the air dispatching device 100 operates in a circulation condition and performs an air circulation function, the air flow formed by the first fan 20 is referred to as a circulation air flow, when the air dispatching device 100 operates in an exhaust condition and performs a ventilation function, the air flow formed by the first fan 20 is referred to as an exhaust air flow, and when the air dispatching device 100 operates in a fresh air condition and performs a fresh air function, the air flow formed by the second fan 30 is referred to as a fresh air flow. The circulating air flows out from the air outlet 1022 and into the room, the exhaust air flows out from the outer air outlet 101 and out to the outside, and the fresh air flows out from the air outlet 1022 and into the room.

Of course, the circulating air temperature control module may also be disposed in the first fan 20, and the fresh air temperature control module may also be disposed in the second fan 30. Of course, only one of the circulating air temperature control module or the fresh air temperature control module can be arranged.

In some embodiments, the blowing duct 103 includes a first vortex duct 1031 extending toward the exhaust port 1022 and communicating with the exhaust port 1022, and the fresh air duct 104 includes a second vortex duct 1041 extending toward the exhaust port 1022 and communicating with the exhaust port 1022. The box plate 12 has a flat plate structure, the direction of the circulating air flow flowing out of the air outlet 1022 is the same as the direction of the fresh air flow flowing out of the air outlet 1022, the two directions are collectively referred to as the air outlet 1022, the air outlet direction is a straight line direction and is perpendicular to the box plate 12, and when the box plate 12 is horizontally installed on one side of the chassis 11 relatively close to the ground, the air outlet direction is vertically downward. The vortex center of the first vortex path 1031 and the vortex center of the second vortex path 1041 both linearly extend along the air outlet direction.

The first vortex 1031 and the second vortex 1041 may be either planar spiral flow paths or spatial spiral flow paths. Taking the first vortex path 1031 as an example, when the first vortex path 1031 is a planar spiral flow path, the plane where the first vortex path 1031 is located is parallel to the box board 12 and perpendicular to the vortex center of the first vortex path 1031, and when the first vortex path 1031 is a space spiral flow path, the first vortex path 1031 extends spirally around a straight line perpendicular to the box board 12, and the straight line is the vortex center of the first vortex path 1031. Whether a planar spiral flow path or a spatial spiral flow path, the circulating air flow will obtain a velocity component that rotates around the vortex center of the first vortex path 1031 after flowing through the first vortex path 1031, and the fresh air flow will obtain a velocity component that rotates around the vortex center of the second vortex path 1041 after flowing through the second vortex path 1041.

For simplicity of description, the vortex center of the first vortex 1031 and the vortex center of the second vortex 1041 are referred to as a first vortex center and a second vortex center, respectively, the circulating air flowing through the first vortex 1031 will form a blowing air column under the constraint and guide action of the first vortex 1031, the axial direction of the blowing air column is parallel to the first vortex center, the fresh air flowing through the second vortex 1041 will form a fresh air column under the constraint and guide action of the second vortex 1041, and the axial direction of the fresh air column is parallel to the second vortex center. The axial direction of the blowing air column and the axial direction of the fresh air column extend along the air outlet direction of the air outlet 1022, and when the box plate 12 is horizontally installed on one side of the chassis 11 relatively close to the ground, the blowing air column and the fresh air column are in a vertically downward form.

The arrangement of the first vortex path 1031 and the second vortex path 1041 improves the shape of the air outlet beam of the circulating air flow and the fresh air flow, relieves the impact of the air beam peak to a user, and can improve the body feeling of the user when the cylindrical air column blows to the body of the user; the blowing air column and the fresh air column can blow the target more accurately and intensively, so that a user can sense the circulating air flow and the fresh air flow more strongly and remarkably; the respective rotational speed components of the blowing air column and the fresh air column can enable the blowing air column and the fresh air column to disturb indoor air more strongly, so that circulating air flow and fresh air flow can be diffused indoors more efficiently; in the process of forming the blowing air column and the fresh air column, the blocking force of the circulating air flow and the fresh air flow is smaller, and compared with the scheme that the air flow is forced to turn by adopting the wind shield to collide with the air flow, the kinetic energy loss of the circulating air flow and the fresh air flow is smaller, so that the circulating air flow and the fresh air flow can be blown to a more distant position, and the circulating air flow and the fresh air flow are more fully diffused.

Specifically, referring to fig. 4, the air duct chamber 10 includes a first air wall 131 and a second air wall 132. One side of the first air wall 131 forms a blowing air channel 103, the first air wall 131 comprises a first arc-shaped wall 1311, the first arc-shaped wall 1311 is used for forming the inner wall of the first vortex channel 1031, the blowing air channel 103 guides circulating air flow to flow along an arc track through the first air wall 131, particularly through the first arc-shaped wall 1311 and gradually approaches the air outlet 1022, and during the period, the circulating air flow obtains a speed component which rotates circumferentially relative to the center of the first vortex; one side of the second air wall 132 forms the fresh air duct 104, the second air wall 132 includes a second arc wall 1321, the second arc wall 1321 is used to form an inner wall of the second vortex path 1041, the fresh air duct 104 guides the fresh air flow through the second air wall 132, especially through the second arc wall 1321, to flow along an arc track and gradually approach the air outlet 1022, during which the fresh air flow obtains a velocity component that circumferentially rotates relative to the center of the second vortex.

The movement of the circulating air flow in the blowing duct 103 includes movement near the air outlet 1022 and rotation about the center of the first vortex, and the movement of the fresh air flow in the fresh air duct 104 includes movement near the air outlet 1022 and rotation about the center of the second vortex. The first vortex path 1031 and the second vortex path 1041 are all circumferentially arranged on the circumference side of the central line of the air outlet 1022, and the central line of the air outlet 1022 passes through the geometric center of the air outlet 1022 and is perpendicular to the box board 12. The first vortex 1031 and the second vortex 1041 direct the circulating air flow and the fresh air flow, respectively, to flow in the same rotational speed direction and out of the exhaust outlet 1022. Referring to fig. 4 to 8, the first vortex path 1031 and the second vortex path 1041 are both disposed around the circumference of the center line of the exhaust port 1022 in a counterclockwise direction, and the air flow rotates around the center line of the exhaust port 1022 in a counterclockwise direction, regardless of whether the air flow flows from the upstream of the first vortex path 1031 to the downstream of the first vortex path 1031 or from the upstream of the second vortex path 1041 to the downstream of the second vortex path 1041.

So set up, the peripheral speed direction of circulating air current relative to first vortex center is the same with the peripheral speed direction of fresh air current relative to second vortex center. The circumferential speed direction of the circulating air flow relative to the first vortex center is the direction of the speed component of the circulating air flow rotating around the first vortex center, and the circumferential speed direction of the fresh air flow relative to the second vortex center is the direction of the speed component of the fresh air flow rotating around the second vortex center.

Fig. 8 shows, by bold dashed lines, the flow path of the circulating air flow in the air blowing duct 103 and the flow path of the fresh air flow in the fresh air flow duct, and the air dispatching device 100 is viewed from below the casing 11 at the viewing angle parallel to the air outlet direction of the air outlet 1022 from the viewing angle of fig. 8, the speed direction of the circulating air flow rotating around the common vortex center is counterclockwise, and the speed direction of the fresh air flow rotating around the common vortex center is counterclockwise.

Referring to fig. 1, 4 to 8, when the first and second scrolls 1031 and 1041 share a common scroll center, the first and second scrolls 1031 and 1041 may be symmetrically disposed about the common scroll center, and may be allowed to rotate about the common scroll center by a certain angle on the basis of the first and second scrolls 1031 and 1041 being symmetrically disposed about the common scroll center.

Preferably, the box plate 12 is provided with an air outlet 1022, the first vortex channel 1031 and the second vortex channel 1041 are both communicated with the air outlet 1022, and a central line of the air outlet 1022 forms a common vortex center of the first vortex channel 1031 and the second vortex channel 1041. So set up, the wind post of blowing is close to more between the wind post with new trend, and the two is similar to a synthetic total wind post, and when air dispatching device 100 operation cycle condition and new trend operating mode simultaneously, the user that is located air dispatching device 100 or bathroom equipment below more easily feels circulation air current and new trend air current, and the somatosensory when blowing is more showing.

Further, the diversion drain 105 further includes a fresh air guide 1052 disposed in the cavity of the chassis 11, i.e., the fresh air guide 1052 is located on the side of the cabinet panel 12 away from the ground.

It will be appreciated that in other embodiments, only one of the air blowing guide 1051 and the fresh air guide 1052 may alternatively be provided.

In some embodiments, the damper 41 is rotatably coupled to the air chute chamber 10, and the first door panel 411 and the second door panel 412 are relatively fixed. When the air door 41 is at the first position, as shown in fig. 4 to 5, at this time, the first door plate 411 opens the air exhaust gap 1312 and seals the air blowing duct 103, the second door plate 412 closes the air inlet 107, the air collection port 1021 is communicated with the air exhaust gap 1312 through the first air inlet 201 and the first air outlet 202 to form an outer through port 101, the space between the first air outlet 202 and the air outlet 1022 is blocked by the first door plate 411, the space between the air intake duct 106 and the outer through port 101 is blocked by the second door plate 412, and the space between the outer through port 101 and the second air outlet 302 cannot be communicated; when the air door 41 is at the second position, as shown in fig. 7 to 8, the first door 411 closes the air exhaust gap 1312 and unblocks the air blowing duct 103, the second door 412 opens the air intake 107, the air collection port 1021 is communicated with the air blowing duct 103 through the first air inlet 201 and the first air outlet 202 to the air outlet 1022, and the outer air port 101 is communicated with the second air inlet 301.

Specifically, the damper mechanism 40 further includes a link mechanism 44, where the link mechanism 44 includes a crank 441 connected to the damper driving member 42, and further includes a transmission link 442 rotatably connected to the crank 441 and the damper member 41, and the damper driving member 42 drives the damper member 41 to rotate relative to the air duct chamber 10 by the transmission link 442 by driving the crank 441 to rotate. Referring to fig. 4 to 8, the damper member 41 is rotatably mounted on the top plate, the damper driving member 42 is fixedly mounted on the top plate, and the damper member 41, the damper driving member 42 and the link mechanism 44 together form a planar four-bar mechanism, wherein the plane of the movement track of the planar screw mechanism is parallel to the box plate 12, so that the space occupation of the damper mechanism 40 in the vertical direction of the box plate 12 is reduced.

Referring to fig. 4, 6-8, in some embodiments, the air duct chamber 10 further includes a movable air wall 45 disposed in the cavity of the chassis 11, and an air wall driving member 46 drivingly connected to the movable air wall 45, where the movable air wall 45 is movably connected to the chassis 11. The position and posture of the movable air wall 45 relative to the chassis 11 include a third position and a fourth position, and the air wall driver 46 is responsible for driving the movable air wall 45 to switch between the third position and the fourth position. When the air door 41 is in the first position, the movable air wall 45 can move to any one of the third position and the fourth position, the movable air wall 45 blocks the fresh air duct 104 to block the second air outlet 302 and the air outlet 1022 when in the third position, and the movable air wall 45 exits and unblocks the fresh air duct 104 when in the fourth position, so that the second air outlet 302 is communicated with the air outlet 1022 through the fresh air duct 104.

When the damper member 41 is in the second position, the position of the movable air wall 45 is determined according to the actual operation condition of the air dispatching device 100: if the air dispatching device 100 only operates the circulation condition and performs the airflow circulation function, the movable air wall 45 may be in the third position or the fourth position; if the air dispatching device 100 only operates the fresh air condition and performs the fresh air function, the movable air wall 45 must be at the fourth position to enable the second air outlet 302 to be communicated with the air outlet 1022 through the fresh air duct 104; if the air dispatching device 100 is operated in both the circulation condition and the fresh air condition, the movable air wall 45 must also be in the fourth position so that the fresh air flows out of the air outlet 1022 through the fresh air duct 104. When the movable air wall 45 is in the fourth position, one side of the movable air wall 45 is a part of the fresh air duct 104, i.e. the movable air wall 45 participates in forming a part of the inner wall of the fresh air duct 104.

Specifically, the fresh air duct 104 section formed by the movable air wall 45 is located on the fresh air duct 104 section formed by the second air wall 132, and the fresh air flow flows through the movable air wall 45, then flows through the second air wall 132, and finally flows out of the air outlet 1022 after leaving the second air outlet 302. In order to reduce the resistance of the fresh air flow flowing in the fresh air duct 104, the movable air wall 45 includes an arc section, and the movable air wall 45 is in smooth transition connection with the high-speed air outlet side of the second air outlet 302 when being located at the fourth position. The high-speed air outlet side of the second air outlet 302 is the side of the air discharge portion 323 of the second volute 32 relatively far from the axis of the second wind wheel 31, and the closer to the high-speed air outlet side of the second air outlet 302, the farther from the axis of the second wind wheel 31, the higher the air outlet speed, due to the centrifugal guiding effect of the second wind wheel 31 on the fresh air flow, among the fresh air flows blown out from the air discharge portion 323. The fresh air flow can then smoothly flow through the movable air wall 45 without being disturbed by the movable air wall 45.

As a preferred embodiment, when the damper member 41 is in the second position and the air dispatching device 100 only operates the circulation condition and performs the air circulation function, the movable air wall 45 is in the third position, and at this time, one end of the movable air wall 45 is smoothly connected to the first air wall 131, and the other end is smoothly connected to the second air wall 132. Specifically, two ends of the movable air wall 45 are respectively connected with the first arc-shaped wall 1311 and the second arc-shaped wall 1321 in a smooth transition manner, and the first arc-shaped wall 1311, the movable air wall 45 and the second arc-shaped wall 1321 sequentially form a circular arc-shaped or elliptical arc-shaped continuous air guiding structure, and the continuous air guiding structure extends around the common vortex center in a bending manner.

So configured, when a portion of the circulating air flow passes over the blowing guide 1051 and fails to form a blowing air column, the portion of the circulating air flow can continue to flow along the movable air wall 45 and the second air wall 132, during which the portion of the circulating air flow continues to obtain a velocity component rotating around the center of the common vortex, and then the portion of the circulating air flow passes through the fresh air guide 1052, and forms a blowing air column again and blows out the air outlet 1022 under the boosting action of the fresh air guide 1052, so that the circulating air flow is prevented from having air loss, and as much circulating air flow as possible forms the blowing air column.

Further, referring to fig. 4 and 6, when the damper 41 is in the first position, one end of the first door panel 411 extends toward the first air outlet 202, and the other end extends toward the outer opening 101, at this time, the first door panel 411 is inclined with respect to both the outer opening 101 and the first air outlet 202, and the indoor air enters the first fan 20 from the air collecting port 1021 and the first air inlet 201 under the driving of the first fan 20, then leaves the first fan 20 from the first air outlet 202, and then flows and turns under the guidance of the first door panel 411 and finally flows to the outside from the outer opening 101, so that the indoor air hardly hits the wall 111 of the chassis 11 under the guidance of the first door panel 411, and the kinetic energy loss is reduced.

Further, referring to fig. 7 to 8, the exhaust notch 1312 is formed between the upstream section of the first air wall 131, that is, a section of the first air wall 131 located upstream of the first arc-shaped wall 1311, and the first fan 20.

The high-speed air outlet side of the first air outlet 202 refers to the junction of the edge of the first volute 22 away from the axis of the first wind wheel 21 and the opening edge of the first air outlet 202. Due to the centrifugal guiding effect of the first wind wheel 21 on the indoor air, the closer to the high-speed wind outlet side of the first wind outlet 202 in the air blown out from the first wind outlet 202 means the farther from the axis of the first wind wheel 21, so that the greater the wind outlet speed, the air can smoothly flow through the first door panel 411, and the air is not blocked by the first door panel 411 to reduce the flow rate, nor is it split by the first door panel 411 to reduce the flow rate.

The second door panel 412 is connected to the end of the upstream section of the first air wall 131 and to the cabinet wall 111 to occupy the air intake space to close the air intake throat 107 when the air flap 41 is in the first position, and the second door panel 412 is disengaged from the cabinet wall 111 to open the air intake throat 107 when the air flap 41 is in the second position.
