Description

Technical Field

[0001] This application relates to the field of air treatment technology, and more particularly to an air treatment device. Background Technology

[0002] Air handling equipment can purify and regulate the temperature of air to meet user needs. For example, air conditioners can easily and quickly provide people with a comfortable indoor temperature environment. Therefore, with the continuous improvement of people's living standards, air conditioners have become an indispensable household appliance in people's daily lives.

[0003] An air conditioner typically consists of an indoor unit and an outdoor unit. The outdoor unit is installed on the outside, and the indoor unit is installed on the inside. The indoor unit has an air outlet. When the air conditioner is running, the indoor unit can deliver cool or warm air into the room through the air outlet, thereby regulating the indoor temperature.

[0004] To change the airflow direction of the indoor unit and thus quickly adjust the indoor temperature, existing air conditioner indoor units generally have an air deflector at the air outlet. Users can rotate the air deflector to change the airflow direction, thereby achieving the purpose of adjusting the indoor temperature in multiple directions. However, existing air deflectors can only adjust the airflow direction within a small angle range, resulting in a limited airflow range for the indoor unit. Summary of the Invention

[0005] This application provides an air handling device to solve the problem of a small air outlet angle in air handling devices.

[0006] This application provides an air handling device, which includes a housing, a heat exchanger, a fan, a volute, and a guide vane. The housing has an internal mounting cavity with an air inlet and an air outlet communicating with it. The heat exchanger and fan are located within the mounting cavity. The fan draws airflow from outside the housing into the mounting cavity through the air inlet, where it passes through the heat exchanger to form a heat-exchange airflow. This heat-exchange airflow is then blown outwards through the air outlet under the fan's operation. The volute is located within the mounting cavity and forms an air duct. One end of the air duct communicates with the air outlet, and the fan is located at the other end. A guide vane is located at the air outlet and rotatably connected to the housing. The guide vane has a sidewall arranged around its rotation axis. The sidewall is designed to rotate clockwise or counterclockwise around the rotation axis to deflect the airflow from the air outlet along the direction of rotation.

[0007] The air handling equipment provided in this application embodiment has a mounting cavity in the casing that provides mounting positions for the components of the air handling equipment. When the fan is running, it draws airflow from outside the casing into the mounting cavity through the air inlet, forming a heat exchange airflow via the heat exchanger. Driven by the fan, the heat exchange airflow is blown outwards from the air outlet. The airflow driven by the fan is guided smoothly into the air duct by the volute and blown out from the air outlet. Because a guide column is provided at the air outlet, when the airflow generated inside the casing passes through the guide column, the user can control the guide column to rotate clockwise or counterclockwise around its axis of rotation. At this time, the airflow passing through the guide column will generate a Magnus effect, that is, the airflow velocity around the sidewalls surrounding the guide column's rotation axis will change, and consequently, the air pressure around the sidewalls will also change. This creates a pressure difference between the airflow around the sidewalls and the air outside the airflow. Under the action of this pressure difference, the flow direction of the airflow passing through the guide column can be significantly deflected along the rotation direction of the guide column. In this way, the air guide column can adjust the direction of the air outlet within a large angle range, making the air handling equipment have a larger air outlet range and higher cooling or heating efficiency.

[0008] In some embodiments, the housing includes a base plate, a top plate, and a side plate located between the top plate and the base plate. The base plate, top plate, and side plate form a mounting cavity, and the side plate has an air inlet and an air outlet.

[0009] There are two air outlets and two air guide columns. The side panel includes a first connecting part and two second connecting parts, wherein the first connecting part is connected to the bottom plate. The two second connecting parts are located on the side of the first connecting part away from the bottom plate and are connected to the first connecting part. A ventilation channel is formed between the two second connecting parts. Each second connecting part has an air outlet, which is located on the side of the second connecting part closest to the ventilation channel, and each air outlet is equipped with an air guide column.

[0010] In some embodiments, the ventilation duct has a first air outlet and a second air outlet arranged opposite to each other, with the two air outlets located on both sides of the first air outlet, and the air guide column located on the side of the air outlet away from the first air outlet.

[0011] In some embodiments, the second connecting portion has a recess on the side away from the mounting cavity, and the recess extends in the same direction as the air outlet. The recess is located on the side of the air outlet away from the first air outlet and is adjacent to the air outlet. A portion of the air guide column is located within the recess.

[0012] In some embodiments, the air guide column includes an air guide body, a first connecting portion, and a second connecting portion. A portion of the air guide body is located within the recess. The air guide body is a cylinder, and the side of the cylinder forms a sidewall. One end of the first connecting shaft is connected to the end face of one end of the air guide body, and the other end is rotatably connected to the housing. One end of the second connecting shaft is connected to the end face of the other end of the air guide body, and the other end is rotatably connected to the housing.

[0013] In some embodiments, the recessed portion has a recessed sidewall, which is a circular arc cylindrical sidewall, and the radius of the circular arc cylindrical sidewall is greater than the radius of the end face of the air guide body.

[0014] In some embodiments, the recessed portion further comprises a recessed bottom wall and a recessed top wall. The recessed bottom wall and the recessed top wall are located at opposite ends of the recessed side wall and are both connected to the recessed side wall. The recessed bottom wall, the recessed top wall, and the recessed side wall form an opening. The angle between the plane containing the edge of the opening and the plane containing the edge of the air outlet is 0° to 20°.

[0015] In some embodiments, the air handling equipment further includes a drive motor disposed within the recess and connected to the top wall of the recess. The output end of the drive motor is connected to a first connecting shaft to drive the air guide body to rotate.

[0016] In some embodiments, the air handling equipment further includes a rotary bearing disposed within a recess and connected to the bottom wall of the recess. A second connecting shaft is disposed at the rotary bearing and rotatably connected to the rotary bearing.

[0017] In some embodiments, the top plate includes two sub-top plates, each sub-top plate being connected to a second connection portion at one end away from the first connection portion. The air handling equipment also includes a cover plate located on the side of the two sub-top plates away from the second connection portion and connected to the two sub-top plates.

Detailed Implementation

[0035] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0036] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure).

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0040] As people's living standards continue to improve, more and more air handling equipment is being used in daily life. Air conditioners, for example, are a common household appliance, typically consisting of an indoor unit and an outdoor unit. The indoor unit is installed indoors, and the outdoor unit is installed outdoors, connected by refrigerant piping. When the air conditioner is running, the refrigerant forms a cooling or heating cycle between the indoor and outdoor units and the refrigerant piping. The indoor unit, located indoors, blows the airflow, after exchanging heat with the refrigerant, into the room, thereby regulating the indoor temperature.

[0041] The air output of air handling equipment directly affects the user experience. To improve the air output range of air handling equipment, this application provides an air handling equipment 100. This air handling equipment 100 can be an indoor air conditioning unit, a wall-mounted unit, a ceiling-mounted unit (embedded unit), a ducted unit (in-ceiling unit), a wall-mounted unit, an air purifier, a fresh air system, a heat exchanger, etc. Among these, indoor air conditioning units are divided into wall-mounted indoor air conditioning units and cabinet indoor air conditioning units. The following description uses a cabinet indoor air conditioning unit as an example.

[0042] See Figure 1 , Figure 1 The exploded view of the air handling equipment 100 provided in the embodiment of this application shows that the air handling equipment 100 may include a housing 2, and an installation cavity 24 is formed inside the housing 2. The installation cavity 24 can provide installation positions for the components of the air handling equipment 100.

[0043] For example, the housing 2 includes a bottom plate 21, a top plate 22, and a side plate 23 located between the bottom plate 21 and the top plate 22, the bottom plate 21, the top plate 22 and the side plate 23 forming a mounting cavity 24.

[0044] See also Figure 1 In some embodiments, the air handling equipment 100 may further include a base 1, with a housing 2 disposed on the base 1, and a bottom plate 21 of the housing 2 connected to the base 1. The base 1 can support the housing 2, so that the bottom plate 21 of the housing 2 is raised a certain height away from the support surface, preventing water or other substances on the support surface from entering the housing 2.

[0045] See Figure 2 , Figure 2 This is a cross-sectional view of an air handling device 100 according to another embodiment of this application. The housing 2 has an air inlet (not shown) communicating with the mounting cavity 24 and an air outlet 231. The air handling device 100 may also include a fan 4 and a heat exchanger 5, both of which are disposed within the mounting cavity 24. In this way, when the fan 4 is operating, it can introduce airflow from outside the housing 2 into the mounting cavity 24 through the air inlet, and form a heat exchange airflow through the heat exchanger 5. Driven by the operation of the fan 4, the heat exchange airflow is blown outwards through the air outlet 231.

[0046] For example, the air inlet (not shown in the figure) and the air outlet 231 can be provided on the side plate 23 of the housing 2.

[0047] See also Figure 2To facilitate the airflow after heat exchange with the heat exchanger 5 within the mounting cavity 24 being blown out through the air outlet 231, the air handling unit 100 may further include a volute 6. The volute 6 is located within the mounting cavity 24 and forms an air duct (not shown in the figure). One end of the air duct is connected to the air outlet 231, and the fan 4 is located at the other end of the air duct. In this way, the airflow driven by the fan 4 can smoothly enter the air duct under the guidance of the volute 6 and be blown out through the air outlet 231.

[0048] For example, the volute 6 consists of two spaced-apart air duct plates, with the space between the two air duct plates forming an air duct.

[0049] To adjust the airflow direction of the air handling unit 100, please refer to [link / reference needed]. Figure 2 The air handling unit 100 may further include an air guide column 3, which is disposed at the air outlet 231 and is rotatably connected to the housing 2. The air guide column 3 has a side wall 31, which is arranged around the rotation axis of the air guide column 3. The side wall 31 is used to rotate clockwise or counterclockwise around the rotation axis so that the airflow blown from the air outlet 231 is deflected along the rotation direction of the side wall 31.

[0050] When the airflow generated inside the housing 2 passes through the guide column 3, the user can control the guide column 3 to rotate. At this time, the airflow passing through the guide column 3 will generate the Magnus effect, that is, the airflow velocity around the side wall 31 set around the rotation axis of the guide column 3 will change, and the air pressure around the side wall 31 will also change. This will create a pressure difference between the airflow around the side wall 31 and the air outside the airflow. Under the action of this pressure difference, the airflow direction passing through the guide column 3 can be deflected significantly along the rotation direction of the guide column 3.

[0051] It should be noted that the principle of the Magnus effect is as follows: Figure 3 As shown, Figure 3This diagram illustrates the principle of the Magnus effect. When the angular velocity vector of a rotating object does not coincide with its velocity vector, a lateral force is generated in a direction perpendicular to the plane formed by the angular velocity and translational velocity vectors. The phenomenon where the object's trajectory deflects under the influence of this lateral force is called the Magnus effect. The reason a rotating object can generate a lateral force is that its rotation causes the surrounding fluid to rotate, increasing the fluid velocity on one side and decreasing it on the other. According to Bernoulli's theorem, increased fluid velocity leads to decreased pressure, and decreased fluid velocity leads to increased pressure, creating a pressure difference in the lateral direction and forming a lateral force. Since this lateral force is perpendicular to the object's direction of motion, it primarily changes the direction of the velocity, forming the centripetal force and thus altering the object's flight direction. Similarly, if an object is fixed and a rotational force is applied to maintain its rotation, while a horizontal flow is applied, the rotating object will change the direction of the horizontal flow.

[0052] Specifically, such as Figure 2 As shown, when the user controls the air guide column 3 to rotate clockwise, a pressure difference will be generated between the airflow blowing from the air outlet 231 around the side wall 31 of the air guide column 3 and the air outside the airflow. This pressure difference forms a force along direction A, and under the action of this force along direction A, the airflow will deflect towards direction A.

[0053] like Figure 4 As shown, Figure 4 This is a cross-sectional view of the air handling device 100 provided in this application embodiment in another working mode. When the user controls the air guide column 3 to rotate counterclockwise, a pressure difference will be generated between the airflow blowing from the air outlet 231 around the side wall 31 of the air guide column 3 and the air outside the airflow. This pressure difference will form a force along the B direction, and the airflow will be deflected in the B direction under the action of the force along the B direction.

[0054] It is understandable that the faster the air guide column 3 rotates, the greater the pressure difference between the airflow around the side wall 31 of the air guide column 3 and the air outside the airflow. This will cause the airflow to deflect at a greater angle after passing through the air guide column 3. Therefore, the air guide column 3 can enable the air handling equipment 100 to have a larger air outlet range.

[0055] In summary, the air handling equipment 100 provided in this embodiment of the application has an air guide column 3 rotatably connected to the housing 2 at the air outlet 231, and the air guide column 3 has a side wall 31 around its rotation axis. The user can control the rotation of the air guide column 3 to make the airflow direction blown out of the air outlet 231 deflect significantly along the rotation direction of the air guide column 3. In this way, the air guide column 3 can adjust the direction of the air outlet within a large angle range, making the air outlet range of the air handling equipment 100 larger and the cooling or heating efficiency higher.

[0056] To further improve the cooling or heating efficiency of the air handling unit 100, in some embodiments, see [reference needed]. Figure 5 , Figure 5 The cross-sectional view of the air handling device 100 provided in the embodiment of this application shows that there can be two air outlets 231 and two air guide columns 3.

[0057] See Figure 6 , Figure 6 This is a schematic diagram of the overall structure of the air handling equipment 100 provided in this embodiment. The side plate 23 may include a first connecting portion 232 and two second connecting portions 233, wherein the first connecting portion 232 is connected to the base plate 21. The two second connecting portions 233 are located on the side of the first connecting portion 232 away from the base plate 21 and are connected to the first connecting portion 232. A ventilation channel 234 is formed between the two second connecting portions 233.

[0058] Each second connection 233 has an air outlet 231, which is located on the side of the second connection 233 near the ventilation channel 234. Each air outlet 231 is provided with an air guide column 3.

[0059] The two air outlets 231, respectively located on the two second connecting parts 233, are respectively connected to the mounting cavity 24 formed by the two second connecting parts 233 and the first connecting part 232. Figure 1 The airflow in the mounting cavity 24 can be blown out from the two air outlets 231. The air from the two air outlets 231 is guided by the air guide column 3 and then blown into the room through the ventilation channel 234. This allows the air handling equipment 100 to have two air outlet positions when it is emitting air, and the cooling or heating efficiency of the air handling equipment 100 is higher.

[0060] Understandably, the first connecting portion 232 of the side plate 23 is arranged around the base plate 21, forming a first sub-mounting cavity. The side of the first sub-mounting cavity away from the base plate 21 has a first sub-mounting cavity opening that communicates with the first sub-mounting cavity. Two second connecting portions 233 are spaced apart on the side of the first connecting portion 232 away from the base plate 21, each forming a second sub-mounting cavity. Both ends of the second connecting portion 233 have second sub-mounting cavity openings that communicate with the second sub-mounting cavity. The second sub-mounting cavity opening at one end of the second connecting portion 233 communicates with the first sub-mounting cavity opening, and the top plate 22 covers the second sub-mounting cavity opening at the other end of the second connecting portion 233.

[0061] To improve the comfort of the air outlet of the air handling unit 100, in some embodiments, see Figure 5 The ventilation duct 234 has a first air outlet 2341 and a second air outlet 2342 arranged opposite to each other. The two air outlets 231 are located on both sides of the first air outlet 2341, and the air guide column 3 is located on the side of the air outlet 231 away from the first air outlet 2341.

[0062] In this way, the user can control one of the air guide columns 3 to rotate clockwise and the other air guide column 3 to rotate counterclockwise, such as... Figure 7 As shown, Figure 7 This is a cross-sectional view of the air handling equipment 100 provided in the embodiments of this application in its working state. Figure 7 The left guide column 3 rotates clockwise and the right guide column 3 rotates counterclockwise. Part of the airflow blown out from the two air outlets 231 can be deflected away from the first air outlet 2341 under the action of the guide columns 3, and the airflow is dispersed. This effectively reduces the hardness of the air outlet of the air handling equipment 100, increases the flexibility of the air outlet of the air handling equipment 100, and improves the comfort of the air outlet of the air handling equipment 100.

[0063] In some embodiments, such as Figure 5 As shown, the two air outlets 231 are respectively angled downward and facing the ventilation channel 234. In this way, the airflow blown out from the two air outlets 231 can be easily discharged into the indoor space through the ventilation channel 234, which improves the cooling or heating efficiency of the air handling equipment 100.

[0064] It is understandable that, such as Figure 7 As shown, when the two air guide columns 3 rotate at a relatively low speed, the air outlet angle of the air handling unit 100 is approximately 60 degrees. At this time, the air outlet of the indoor unit is more concentrated, and the airflow feels stronger. Figure 8 As shown, Figure 8This is a cross-sectional view of the air handling unit 100 provided in the embodiment of this application in the medium-speed airflow mode. When the two air guide columns 3 rotate at a moderate speed, the air outlet angle of the air handling unit 100 is approximately 120 degrees. At this time, the airflow dispersion of the indoor unit is moderate, and the airflow is moderate. Figure 9 As shown, Figure 9 This is a cross-sectional view of the air handling device 100 provided in the embodiment of this application in the windless mode. When the two air guide columns 3 rotate at a high speed, the air outlet angle of the air handling device 100 can approach 180 degrees. At this time, the airflow blown out by the air handling device 100 is more diffuse and the air outlet range is larger, so that the room can achieve the effect of coolness without wind.

[0065] Because the air handling unit 100, with its dual-tower structure and two air outlets 231, can have an air outlet angle range approaching 180 degrees, users can place it in various locations within a room. For example, such as... Figure 10 As shown, Figure 10 This is a schematic diagram of the air handling unit 100 provided in this embodiment of the application placed in the central area of ​​room C. In this case, the air handling unit 100 can supply air to the left and right sides of room C respectively, essentially achieving whole-room air supply. Figure 11 As shown, Figure 11 This is a schematic diagram of the air handling device 100 provided in this application embodiment placed in the corner area of ​​room C. At this time, the air handling device 100 can supply air to the upper left and lower right parts of room C, and can basically achieve the effect of whole-house air supply.

[0066] Of course, users can also control the two air guide columns 3 to rotate at different speeds, so that the two sides corresponding to the two air guide columns 3 have different air outlet ranges and air outlet intensities, thereby meeting various user needs. For example, as shown in... Figure 12 As shown, Figure 12 A cross-sectional view of the air handling device 100 provided in the embodiments of this application in the dual-fan mode, wherein, Figure 12 The left air guide column 3 rotates clockwise at high speed, while the right air guide column 3 rotates counterclockwise at low speed. At this time, the airflow on the left side of the first air outlet 2341 is weak, while the airflow on the right side is strong. In addition, the user can control the rotation speed of the air guide column 3 to continuously change the dispersion of the airflow, making the airflow intensity of the air handling unit 100 fluctuate, thus achieving the effect of disordered natural wind in the indoor unit's airflow.

[0067] Additionally, when the air handling unit 100 is designed as the aforementioned dual-tower structure with two air outlets 231, such as Figure 13 As shown, Figure 13This is a cross-sectional view of the air handling unit 100 provided in this embodiment of the application in the state of a stationary air guide column 3. The airflow from the two air outlets 231 is blown out from the first air outlet 2341. The airflow velocity at the first air outlet 2341 is faster and the air pressure is lower, while the indoor air velocity in the ventilation duct is slower and the air pressure is higher. There is a pressure difference between the airflow at the first air outlet 2341 and the air in the ventilation duct. Under the action of this pressure difference, the indoor air will enter the ventilation duct from the second air outlet 2342 and then be blown out from the first air outlet 2341, mixing with the airflow at the first air outlet 2341. In this way, the airflow blown out of the air outlet 231 by the air handling unit 100 will mix with the indoor air in the ventilation duct before being sent into the room. This makes the outlet air temperature of the air handling unit 100 more suitable, and the user will feel more comfortable when the air from the indoor unit blows to the user.

[0068] To improve the airflow dispersion effect of the guide column 3, in some embodiments, see... Figure 7 The second connecting portion 233 has a recess 2331 on the side away from the mounting cavity 24, and the extending direction of the recess 2331 is the same as the extending direction of the air outlet 231. The recess 2331 is located on the side of the air outlet 231 away from the first air outlet 2341 and is adjacent to the air outlet 231. A portion of the air guide column 3 is located within the recess 2331.

[0069] When the air handling unit 100 is discharging air, the recessed portion 2331 receives virtually no air. The airflow blowing out from the outlet 231 primarily contacts the sidewall 31 of the guide column 3 closest to the outlet 231. This allows the portion of the sidewall 31 of the guide column 3 closest to the outlet 231 to accelerate the airflow velocity, causing a portion of the airflow in contact with the sidewall 31 to deflect away from both outlets 231. This significantly improves the airflow dispersion effect of the guide column 3.

[0070] To further improve the airflow dispersion effect of the guide column 3, in some embodiments, see Figure 6 The air guide column 3 may include an air guide body 32. See also Figure 7 A portion of the air guide body 32 is located within the recess 2331. The air guide body 32 is a cylinder, and the side of the cylinder is a sidewall 31.

[0071] The air guide body 32 of the air guide column 3 is cylindrical in shape, so that the airflow can easily flow around the side wall 31 of the air guide body 32. This is more conducive to changing the airflow velocity around the side wall 31 of the air guide body 32, and thus makes it easier to disperse the airflow with the air guide column 3. The air guide column 3 has a better airflow dispersion effect.

[0072] Of course, the air guide body 32 can also be configured as a regular pentagonal prism, a regular hexagonal prism, a regular octagonal prism, etc., as long as the side wall 31 of the air guide body 32 can drive the airflow around it, thereby changing the flow rate of the airflow around the air guide body 32.

[0073] In some embodiments, see Figure 6 The air guide column 3 may also include a first connecting shaft 33 and a second connecting shaft 34. One end of the first connecting shaft 33 is connected to the end face of one end of the air guide body 32, and the other end is rotatably connected to the housing 2. One end of the second connecting shaft 34 is connected to the end face of the other end of the air guide body 32, and the other end is rotatably connected to the housing 2.

[0074] By setting a first connecting shaft 33 and a second connecting shaft 34 at both ends of the air guide body 32, the air guide column 3 can be rotatably connected to the housing 2 through the first connecting shaft 33 and the second connecting shaft 34, making the rotatable connection between the air guide column 3 and the housing 2 easier to achieve.

[0075] To facilitate the installation of the air guide body 32 within the recess 2331, in some embodiments, see [reference needed]. Figure 7 The recessed portion 2331 has a recessed sidewall 2332, which is a circular arc cylindrical sidewall 31. The radius of the circular arc cylindrical sidewall 31 is larger than the radius of the end face of the air guide body 32.

[0076] By designing the recess 2331 to be circular in shape to match the shape of the air guide body 32, the air guide body 32 can be easily installed inside the recess 2331. Furthermore, the recessed sidewall 2332 of the recess 2331 surrounds the air guide body 32, thereby greatly reducing the possibility of airflow entering the gap between the air guide body 32 and the recessed sidewall 2332, ensuring that the air guide column 3 has a good air dispersion effect.

[0077] In some embodiments, see continue to see Figure 7 The recessed sidewall 2332 of the recessed portion 2331 can be concentrically set with the air guide body 32, which further reduces the possibility of airflow being blown into the gap between the air guide body 32 and the recessed sidewall 2332.

[0078] To further prevent airflow from entering the gap between the air guide body 32 and the recessed sidewall 2332, in some embodiments, see [reference needed]. Figure 6 The recessed portion 2331 also has a recessed bottom wall 2333 and a recessed top wall 2334. The recessed bottom wall 2333 and the recessed top wall 2334 are located at both ends of the recessed side wall 2332 and are both connected to the recessed side wall 2332. The recessed bottom wall 2333, the recessed top wall 2334, and the recessed side wall 2332 form an opening.

[0079] Among them, such as Figure 5 As shown, the angle α between the plane containing the edge of the opening and the plane containing the edge of the air outlet 231 is 0° to 20°.

[0080] When the angle between the plane containing the edge of the opening formed by the recessed bottom wall 2333, the recessed top wall 2334, and the recessed side wall 2332 in the recessed portion 2331 and the plane containing the edge of the air outlet 231 is greater than 20°, the airflow blowing from the air outlet 231 has a small contact area with the side wall 31 of the air guide body 32, or the airflow blowing from the air outlet 231 is easily blown into the gap between the air guide body 32 and the recessed side wall 2332, resulting in poor air dispersion effect of the air guide column 3. However, when the angle between the plane containing the edge of the opening and the plane containing the edge of the air outlet 231 is 0° to 20°, the airflow blowing from the air outlet 231 has a large contact area with the side wall 31 of the air guide body 32, and can also minimize the airflow from being blown into the gap between the air guide body 32 and the recessed side wall 2332, so that the air guide column 3 has a better air dispersion effect.

[0081] To achieve the rotation of the air guide column 3, in some embodiments, see further details. Figure 6 The air handling unit 100 may further include a drive motor 7, which is disposed within the recess 2331 and connected to the top wall 2334 of the recess. The output end of the drive motor 7 is connected to the first connecting shaft 33 to drive the air guide body 32 to rotate.

[0082] The drive motor 7 located at one end of the air guide column 3 can provide power for the rotation of the air guide body 32 in the air guide column 3. Users can change the deflection direction and deflection angle of the airflow by controlling the rotation direction and speed of the drive motor 7, thereby realizing multiple air outlet modes of the air handling equipment 100.

[0083] To reduce the resistance experienced by the air guide column 3 during rotation, in some embodiments, see further details. Figure 6 The air handling unit 100 may further include a rotary bearing 8, which is disposed within the recess 2331 and connected to the bottom wall 2333 of the recess. A second connecting shaft 34 is disposed at the rotary bearing 8 and is rotatably connected to the rotary bearing 8.

[0084] Because the bearing has an extremely low coefficient of friction, the second connecting shaft 34 of the air guide column 3 is rotatably connected to the recessed bottom wall 2333 through the bearing, which can effectively reduce the resistance encountered by the air guide column 3 during rotation, making the rotation of the air guide column 3 easier to achieve.

[0085] In some embodiments, the first connecting shaft 33 is connected to the end face of the air guide body 32 away from the base, the second connecting shaft 34 is connected to the end face of the air guide body 32 near the base, the drive motor 7 is located on the side of the air guide column 3 away from the base, and the rotating bearing 8 is located on the side of the air guide column 3 near the base. In this way, the condensate generated on the heat exchanger 5 during the operation of the air handling equipment 100 is less likely to enter the drive motor 7, thereby improving the service life of the drive motor 7.

[0086] When the housing 2 of the air handling unit 100 has two second connecting portions 233 to form a double-tower structure, in order to improve the structural stability of the air handling unit 100, in some embodiments, see continue to the previous section. Figure 6 The top plate 22 includes two sub-top plates 221, each sub-top plate 221 being connected to a second connection portion 233 at one end away from the first connection portion 232; the air handling equipment 100 may also include a cover plate 9, which is located on the side of the two sub-top plates 221 away from the second connection portion 233 and is connected to the two sub-top plates 221.

[0087] By setting a cover plate 9 and connecting the cover plate 9 to the sub-top plate 221 above the two second connecting parts 233, the upper ends of the two second connecting parts 233 are mutually restricted during the operation of the air handling equipment 100 under the connection and fixing effect of the cover plate 9, which effectively reduces the possibility of vibration at the upper ends of the two second connecting parts 233 during the operation of the air handling equipment 100, thereby improving the structural stability of the air handling equipment 100.

[0088] To facilitate the use of the air handling unit 100, in some embodiments, the air handling unit 100 may further include a controller. The controller stores parameters for various rotation states of the air guide column 3, allowing the user to retrieve different parameters from the controller to meet different usage needs. For details, see [link to relevant documentation]. Figure 14 , Figure 14 The control logic diagram of the air handling equipment 100 provided in this application embodiment shows that when the air handling equipment is started, the user can use a remote control to retrieve different operating parameters in the controller according to their own usage needs, thereby causing the air guide column 3 of the air handling equipment 100 to rotate according to the corresponding operating parameters.

[0089] To reduce the risk of external debris entering the housing 2, in some embodiments, see Figure 7 The air handling unit 100 may also include a baffle 10 located at the air outlet 231. Under the action of the drive mechanism and the transmission mechanism, the baffle 10 can open or close the air outlet 231.

[0090] In this way, when the air handling unit 100 is working, the baffle 10 opens the air outlet 231 under the action of the drive mechanism and the transmission mechanism, and the air from the indoor unit can be blown out from the air outlet 231. When the air handling unit 100 is turned off, the baffle 10 closes the air outlet 231 under the action of the drive mechanism and the transmission mechanism. This can effectively prevent external debris from entering the casing 2 and improve the service life of the air handling unit 100.

[0091] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
