The air handling apparatus 100 further includes a damper mechanism 40, the damper mechanism 40 includes a damper member 41 and a damper driving member 42 drivingly connected to the damper member 41, the damper member 41 is movably mounted to the air duct box 10 and includes a first door panel 411 and a second door panel 412 connected to each other, the position and the posture of the damper member 41 relative to the air duct box 10 include a first position and a second position, and the damper driving member 42 drives the damper member 41 to switch between the first position and the second position, specifically:

When the air door 41 is at the first position, the first door panel 411 opens the air outlet gap 1312, the first air outlet 202 is communicated with the outer through hole 101 through the air outlet gap 1312, so that the first air outlet 202 is open to the outer through hole 101, the second door panel 412 closes the air inlet throat 107 and blocks the air inlet duct 106 from the outer through hole 101, and thus the second air inlet 301 is blocked from the outer through hole 101;

When the damper 41 is in the second position, the first door 411 closes the exhaust notch 1312, the first air outlet 202 is blocked from the outer opening 101, and the second door 412 opens the air inlet 107 and unblocks the air inlet duct 106 from the outer opening 101, so that the second air inlet 301 is unblocked from the outer opening 101.

Further, in some embodiments, when the damper 41 is in the first position, the first door panel 411 blocks the blowing duct 103, and thus the first air outlet 202 and the air outlet 1022 are blocked; when the air door 41 is in the second position, the first door 411 unblocks the air blowing duct 103, and the first air outlet 202 communicates with the air blowing duct 103, so that the space between the first air outlet 202 and the air outlet 1022 is unblocked. When the air door piece 41 is in the first position, the air conditioning 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 handling device 100 can operate the circulation condition and perform the air circulation function, can also operate the fresh air condition and perform the fresh air function, and can also operate the circulation condition and the fresh air condition simultaneously.

For simplicity of description, when the air conditioning apparatus 100 operates in a circulation mode 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 conditioning apparatus 100 operates in an exhaust mode 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 conditioning apparatus 100 operates in a fresh air mode 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. Since both the circulating air flow and the fresh air flow are air flows delivered into the room by the air handling unit 100, the circulating air flow and the fresh air flow may be collectively referred to as an air outlet air flow, and it should be understood that in other embodiments, the air outlet air flow is not limited to the circulating air flow and the fresh air flow, and all the air flows along the duct leading to the air outlet 1022 and is discharged from the air outlet 1022 into the room belong to the air outlet air flow.

Optionally, the air handling device 100 further includes a temperature adjustment module for adjusting the temperature of the air outlet airflow, where the temperature adjustment module can adjust the temperature of the circulating airflow or the fresh air airflow blown into the room, so as to change the indoor air temperature and improve the temperature comfort of the user during use. The temperature adjusting module may include a circulating air temperature control module disposed in the blowing air duct 103, and may also include a fresh air temperature control module disposed in the fresh air duct 104. It will be appreciated that the circulating air temperature control module may also be disposed within the first fan 20, and the fresh air temperature control module may also be disposed within the second fan 30. In some embodiments, only one of the circulating air temperature control module or the fresh air temperature control module may be provided.

In some embodiments, the blowing duct 103 includes a first scroll 1031 extending toward the exhaust port 1022 to thereby open to the exhaust port 1022, and the fresh air duct 104 includes a second scroll 1041 extending toward the exhaust port 1022 to thereby open to the exhaust port 1022. Specifically, the end of the first vortex path 1031 is directly connected to the air outlet 1022, and the end of the second vortex path 1041 is directly connected to the air outlet 1022. The box plate 12 has a plate-like structure, and 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, and the two directions are collectively referred to as the air outlet direction of the air outlet 1022. In some embodiments, the box board 12 is a flat plate structure, and the air outlet direction is a straight line direction and is perpendicular to the box board 12, and when the box board 12 is horizontally installed on a 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 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, a plane where the extending guiding spiral of the first vortex path 1031 is located is parallel to the box plate 12 and perpendicular to the vortex center of the first vortex path 1031; 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 path 1031 and the vortex center of the second vortex path 1041 are respectively referred to as a first vortex center and a second vortex center, the circulating air flow flowing through the first vortex path 1031 forms a blowing air column under the constraint and guide action of the first vortex path 1031, the axial direction of the blowing air column is parallel to the first vortex center, in the blowing air column, the flow track of the circulating air flow is spiral, the fresh air flow flowing through the second vortex path 1041 forms a fresh air column under the constraint and guide action of the second vortex path 1041, the axial direction of the fresh air column is parallel to the second vortex center, and in the fresh air column, the flow track of the fresh air flow is spiral. 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 close to the ground, the blowing air column and the fresh air column are in a vertical downward form.

The blowing air column and the fresh air column can be collectively called as an air outlet column, the first vortex channel 1031 and the second vortex channel 1041 improve the shape of the air outlet column, alleviate the impact of the peak of the air outlet column on a user, and prevent the air outlet column from directly blowing the user; the guiding effect of the first vortex path 1031 and the second vortex path 1041 on the air outlet air flow enables the air outlet air flow to obtain a rotating speed component, so that the air flow in the air outlet air column can blow a user at an inclined angle, even part of the air outlet air flow blows the user at a flow track tangential or approximately tangential to the surface of a human body, and the body feeling of the user can be improved; 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.

When the air door 41 is in the second position as shown in fig. 7 to 8, the indoor air may enter the air collection port 1021 and flow through the first fan 20, the air blowing duct 103 and the air outlet 1022 in sequence, the outdoor air may enter the outer air collection port 101 and flow through the air inlet duct 106, the second fan 30, the fresh air duct 104 and the air outlet 1022 in sequence, which is equivalent to that the indoor air is injected into the air duct box 10 through the air collection port 1021 and the outdoor air is injected into the air duct box 10 through the outer air collection port 101, so that the air collection port 1021 and the outer air collection port 101 may be collectively referred to as an air injection port at this time; the air blowing duct 103 and the fresh air duct 104 are respectively communicated with the air collecting port 1021 and the outer through port 101, and both are led to the air outlet 1022, so that the air blowing duct 103 and the fresh air duct 104 can be collectively called as an air supply duct at this time, and the first vortex duct 1031 and the second vortex duct 1041 are both equivalent to the vortex duct of the air supply duct.

It will be appreciated that in other embodiments, the air inlet is not limited to the air collection port 1021 and the outer port 101, the air supply duct is not limited to the air blowing duct 103 and the fresh air duct 104, and the scroll duct is not limited to the first scroll duct 1031 and the second scroll duct 1041, and when the duct box 10 is provided with other openings for air to enter the duct box 10, and the duct box 10 includes a duct communicating with the openings and leading to the air outlet 1022, the openings also belong to the air inlet, the duct also belongs to the air supply duct, and accordingly, the duct may also include a scroll duct leading to the air outlet 1022.

Further, referring to fig. 4, the air duct box 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 and gradually approaches the air outlet 1022 by virtue of the first air wall 131, and during the period, the circulating air flow obtains a speed component which rotates circumferentially relative to the center of the first vortex; the second air wall 132 forms the fresh air duct 104 on one side, and the second air wall 132 includes a second arc wall 1321, where the second arc wall 1321 is used to form an inner wall of the second vortex path 1041, and the fresh air duct 104 guides the fresh air flow by means of the second air wall 132, especially by means of 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.

In some embodiments, the movement of the circulating air stream within the blowing duct 103 includes both movement proximate the exhaust port 1022 and rotation about the first vortex center, and the movement of the fresh air stream within the fresh air duct 104 includes both movement proximate the exhaust port 1022 and rotation about the second vortex center. The first vortex path 1031 and the second vortex path 1041 are both arranged around the circumference of the central line of the air outlet 1022 in the same rotation direction, 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 and second scroll 1031 and 1041 guide the circulating and fresh air streams, respectively, to flow around the center line of the exhaust port 1022 at the same rotational speed direction. 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.

The circumferential speed direction of the circulating air flow relative to the first vortex center is the same as the circumferential speed direction of the fresh air flow relative to the 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.

In the embodiment shown in fig. 4-8, the first vortex center and the second vortex center approximately coincide, and the first vortex path 1031 and the second vortex path 1041 can be regarded as sharing the same common vortex center, and the common vortex center is perpendicular to the box plate 12 and has an extension direction parallel to the air outlet direction of the air outlet 1022. Fig. 8 shows, with bold broken 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 from the view point of fig. 8, the air handling apparatus 100 is viewed under the casing 11 at an observation angle parallel to the air outlet direction of the air outlet 1022, 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.

In other embodiments, one of the first and second scrolls 1031, 1041 may also be rotated about the common scroll center by a certain angle on the basis of symmetry of the first and second scrolls 1031, 1041 about the common scroll center.

Optionally, the first vortex center and the second vortex center are located between the first arc-shaped wall 1311 and the second arc-shaped wall 1321, and the first arc-shaped wall 1311 and the second arc-shaped wall 1321 wind the first vortex center and the second vortex center in the same rotation direction; or the center line of the air outlet 1022 passes between the first arc-shaped wall 1311 and the second arc-shaped wall 1321, and the first arc-shaped wall 1311 and the second arc-shaped wall 1321 wind around the center line of the air outlet 1022 in the same rotation direction.

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 air-out wind post, and when air conditioning fortune device 100 operation circulation operating mode and new trend operating mode simultaneously, the user that is located air conditioning fortune device 100 or bathroom equipment below is felt circulation air current and new trend air current simultaneously more easily, and the somatosensory when blowing is more showing.

When the first arc-shaped wall 1311 guides the circulating air flow away from the first air outlet 202 to flow to the air outlet 1022, the flowing direction of the circulating air flow is the drainage direction of the first vortex path 1031, and when the second arc-shaped wall 1321 guides the fresh air flow away from the second air outlet 302 to flow to the air outlet 1022, the flowing direction of the fresh air flow is the drainage direction of the second vortex path 1041.

In some embodiments, the air duct box 10 further includes a diverting and guiding portion 105, and the diverting and guiding portion 105 includes a blowing guide 1051 disposed in the chassis 11, that is, the blowing guide 1051 is located on a side of the box plate 12 away from the ground. A first gap is formed between the air blowing guide plate 1051 and one side of the box plate 12 facing away from the ground, the first gap is used for forming at least a part of the air blowing air channel 103, and the first gap forms at least a part or all of the first vortex channel 1031, the height of the first gap is in a decreasing trend along the direction close to the air outlet 1022, as the circulating air flow leaves the first air outlet 202 and flows towards the air outlet 1022 along the air blowing air channel 103, the distance from one side of the air blowing guide plate 1051 close to the box plate 12 is in a decreasing trend, the part of the air blowing air channel 103 corresponding to the first gap is narrowed along the direction close to the air outlet 1022, that is, the height of the first gap is decreased along the drainage direction of the first vortex channel 1031, and the air blowing guide plate 1051 applies a boosting force to the circulating air flow to enable the circulating air flow to obtain a lateral moving speed so as to make a turning and flow out of the air outlet 1022.

The diversion drain 105 further includes a fresh air guide 1052 disposed within the chassis 11, i.e., the fresh air guide 1052 is located on a side of the deck 12 remote from the floor. A second gap is formed between the fresh air guide plate 1052 and one side of the box plate 12 facing away from the ground, the second gap is used for forming at least a part of the fresh air duct 104, and the second gap forms at least a part or all of the second vortex duct 1041, the height of the second gap is in a decreasing trend along the direction close to the air outlet 1022, as the fresh air flow leaves the second air outlet 302 and flows towards the air outlet 1022 along the fresh air duct 104, the distance from one side of the fresh air guide plate 1052 close to the box plate 12 is in a decreasing trend, and the part of the fresh air duct 104 corresponding to the second gap is narrowed along the direction close to the air outlet 1022, that is, the height of the second gap is decreased along the drainage direction of the second vortex duct 1041, the fresh air guide plate applies a boosting force to the fresh air flow so that the fresh air flow obtains a lateral moving speed to turn and flow out of the air outlet 1022.

The provision of the air blowing guide plate 1051 promotes the formation of an air blowing column, the circulating air flows basically along the direction parallel to the box plate 12 before the circulating air reaches the first gap, and the boosting action of the circulating air by the air blowing guide plate 1051 enables the circulating air to obtain the flow speed in the vertical direction of the box plate 12, so that the circulating air can flow out of the air outlet 1022 more easily with smaller resistance after turning, and finally the air blowing column vertical to the box plate 12 is formed; similarly, the provision of the fresh air guide 1052 facilitates the formation of a fresh air column, and the fresh air flow is substantially parallel to the box plate 12 before reaching the second gap, and the boost action of the fresh air guide 1052 on the fresh air flow imparts a velocity to the fresh air flow in the vertical direction of the box plate 12 so that the fresh air flow may more easily flow out of the exhaust port 1022 with less resistance after turning.

Referring to fig. 4, 6-8, in some embodiments, the air duct box 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 handling device 100: if the air conditioning device 100 only operates in the circulation mode and performs the airflow circulation function, the movable air wall 45 may be in the third position or the fourth position; if the air handling 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 communicate with the air outlet 1022 through the fresh air duct 104; if the air handling unit 100 is operating in both the circulation mode and the fresh air mode, the movable air wall 45 must also be in the fourth position so that 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 moving device 100 is only operated in the circulation mode 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.
