Abstract

This application relates to the field of evaporation and condensation technology, and more particularly to an air distribution box and duct unit. The air distribution box includes a box body, a limiting post, and an air guide plate assembly. The bottom surface of the box body is provided with a vertical air outlet, and the side surface of the box body is provided with a horizontal air outlet. The limiting post is disposed within the horizontal air outlet, and the limiting post includes a rigid rod and an elastic covering layer covering the rigid rod. The air guide plate assembly is used to close or open the horizontal air outlet. By closing or opening the horizontal air outlet and the vertical air outlet through the air guide plate assembly, air can be supplied in two directions. At the same time, the structural characteristics of the rigid rod make the air guide plate assembly less prone to bending and deformation after contacting the limiting post. The elastic covering layer forms a better sealing effect after contacting the air guide plate assembly, avoiding condensation and air leakage caused by poor sealing between the air guide plate assembly and the limiting post.

Description

Technical Field

[0001] This application relates to the field of evaporation and condensation technology, and in particular to a distribution box and duct system. Background Technology

[0002] Ductless air conditioners (or ducted air conditioners), commonly known as ducted units, deliver air to the room through ducts. They are small-scale all-air systems. However, current ductless units only have one air outlet and can usually only deliver air in one direction, resulting in a relatively simple air delivery mode. Furthermore, when multiple air guides are used to switch the opening and closing of one air outlet of the unit, the air guides may not be able to seal properly due to their long length and insufficient rigidity, leading to condensation and air leakage. Utility Model Content

[0003] This application provides an air distribution box, a duct air conditioner and its control method, which can solve the problems of existing duct air conditioners having only one air outlet, only able to supply air in one direction, having a single air supply mode, and having condensation and air leakage caused by poor sealing.

[0004] In a first aspect, this application provides a distribution box, which includes:

[0005] The enclosure has a vertical air outlet on its bottom surface and a horizontal air outlet on its side surface.

[0006] A limiting post is provided inside the horizontal air outlet. The limiting post includes a rigid rod and an elastic covering layer covering the outside of the rigid rod.

[0007] The air guide plate assembly includes an upper air guide plate rotatably disposed above the horizontal air outlet and a lower air guide plate rotatably disposed below the horizontal air outlet. The air guide plate assembly is used to close or open the horizontal air outlet. When the air guide plate assembly closes the horizontal air outlet, the air guide plate assembly abuts against the limiting post. The lower air guide plate is also used to close or open the vertical air outlet.

[0008] Furthermore, with the horizontal air outlet closed, the ends of the upper and lower air guide plates away from their rotation axes abut against the limiting post.

[0009] Furthermore, with the horizontal air outlet closed, a gap is formed between the ends of the upper air guide plate and the lower air guide plate that are away from their respective axes of rotation.

[0010] Furthermore, the vertical dimension of the gap is 4mm to 6mm.

[0011] Furthermore, the limiting post is horizontally positioned inside the horizontal air outlet, and the two ends of the limiting post are respectively connected to both sides of the horizontal air outlet in the width direction.

[0012] Furthermore, with the horizontal air outlet closed, the upper air guide plate abuts against the limiting post, and the lower air guide plate abuts against the side of the upper air guide plate opposite to the limiting post; or

[0013] With the horizontal air outlet closed, the lower air guide plate abuts against the limiting post, and the upper air guide plate abuts against the side of the lower air guide plate away from the limiting post.

[0014] Furthermore, with the horizontal air outlet closed, the vertical dimension of the overlapping area between the upper air guide plate and the lower air guide plate is 6-15mm.

[0015] Furthermore, when the upper air guide plate and the lower air guide plate form an overlapping area, the contact surface of the upper air guide plate and the lower air guide plate in the overlapping area is a flexible material layer.

[0016] Furthermore, the limiting post includes a first limiting post and a second limiting post horizontally disposed within the horizontal air outlet. The first limiting post is connected to one side of the horizontal air outlet in the width direction, and the second limiting post is connected to the other side of the horizontal air outlet in the width direction.

[0017] Furthermore, the limiting post is horizontally positioned inside the horizontal air outlet, and the middle part of the limiting post is connected to the upper edge and / or lower edge of the horizontal air outlet via a connecting rod.

[0018] Furthermore, both the upper air guide plate and the lower air guide plate are multi-layered assembly structures, with the outer layer consisting of the flexible material layer and the plastic shell.

[0019] Furthermore, a reinforcing plate is provided inside the end of both the upper and lower air guide plates that is away from their rotation axis.

[0020] Secondly, embodiments of this application provide a ductwork unit, which includes:

[0021] Fan system;

[0022] The heat exchange system is connected to the fan system;

[0023] The air distribution box is located on the air outlet side of the heat exchange system.

[0024] The technical solutions provided in this application have the following advantages compared with the prior art:

[0025] The air distribution box and duct air conditioner provided in this application embodiment, by setting a vertical air outlet on the bottom surface of the air distribution box and a horizontal air outlet on the side end face of the air distribution box, and rotatably setting an air guide plate assembly at the horizontal air outlet, can close or open the horizontal air outlet and the vertical air outlet through the air guide plate assembly, so as to achieve air supply in two directions. That is, the duct air conditioner arranged in the area between the dining room and the living room can supply air to the dining room and the living room separately or simultaneously; at the same time, the limiting column is designed to include a rigid rod and an elastic element covering the outside of the rigid rod. The covering layer utilizes the structural characteristics of the rigid rod to prevent the air guide plate assembly from bending or deforming even if the limiting post is long after it comes into contact with the rigid rod. Furthermore, the elastic covering layer, which is wrapped around the rigid rod, forms a better seal when it comes into contact with the air guide plate assembly, preventing condensation and air leakage caused by poor sealing between the air guide plate assembly and the limiting post. Moreover, the elastic covering layer is made of elastic materials such as rubber, silicone, and plastic, which can buffer the air guide plate assembly when it comes into contact with the limiting post, preventing damage to both the limiting post and the air guide plate assembly.

[0050] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, 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, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0051] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0052] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0053] Currently, ducted air conditioners are the mainstream indoor unit terminal form of central air conditioning due to their aesthetically pleasing installation and space-saving design. The increasingly popular continuous air outlet style in recent years further enhances their minimalist and sophisticated look, making them highly favored by younger consumers. However, conventional ducted air conditioners typically have only one air outlet. For some apartment layouts where the air conditioner is installed in the ceiling between the dining room and living room, users often need to install two units, one with an air outlet facing the dining room and the other facing the living room, with a return air vent at the bottom. This results in high overall unit costs and an unsightly appearance. This proposal addresses this by designing a new type of ducted air conditioner and its air outlet components to achieve multiple air delivery modes. Specifically, it can simultaneously deliver air in two different directions, meeting user needs while offering an aesthetically pleasing installation, although at a higher cost. When the horizontal air outlet of the unit uses two or more sealing plates for switching between closing and opening, the guide plates may lack rigidity due to their length, leading to inadequate sealing, condensation, and air leakage.

[0054] like Figure 1-11 As shown, to address the aforementioned technical problems, this application provides an air distribution box 100, whose main structure includes a box body 110, a limiting post 120, and an air guide plate assembly. The bottom surface of the box body 110 is provided with a vertical air outlet 111, and the side surface of the box body 110 is provided with a horizontal air outlet 112. The limiting post 120 is disposed within the horizontal air outlet 112, and the limiting post 120 includes, as shown in the figure... Figure 2 The rigid rod 121 and the elastic covering layer 122 covering the rigid rod 121 are shown. The air guide plate assembly includes an upper air guide plate 130 rotatably disposed above the horizontal air outlet 112 and a lower air guide plate 140 rotatably disposed below the horizontal air outlet 112. The air guide plate assembly is used to close or open the horizontal air outlet 112. When the air guide plate assembly closes the horizontal air outlet 112, the air guide plate assembly abuts against the limiting post 120. The lower air guide plate 140 is also used to close or open the vertical air outlet 111.

[0055] like Figure 8-11 As shown, the upper air guide plate 130 stops at the following positions during rotation: first position A and second position B. The lower air guide plate 140 stops at the following positions during rotation: third position C, fourth position D, and fifth position E. The upper air guide plate 130 at first position A is used to block the upper area of ​​the horizontal air outlet 112; the upper air guide plate 130 at second position B is used to open the upper area of ​​the horizontal air outlet 112; the lower air guide plate 140 at third position C is used to block the lower area of ​​the horizontal air outlet 112; the lower air guide plate 140 at fifth position E is used to block the vertical air outlet 111 and open the lower area of ​​the horizontal air outlet 112; the lower air guide plate 140 at fourth position D is located between third position C and fifth position E.

[0056] When vertical airflow is required, the upper air guide plate 130 and the lower air guide plate 140 rotate to the first position A and the third position C, respectively, to close the horizontal air outlet 112. The inner surface of the air guide plate assembly is tightly fitted with the elastic covering layer 122 of the horizontally extending limiting post 120. At the same time, the lower air guide plate 140 opens the vertical air outlet 111, allowing airflow to be delivered from the vertical air outlet 111. A sweeping structure can also be provided at the vertical air outlet 111 as needed to further adjust the direction of airflow from the vertical air outlet 111. For example, the sweeping structure can further adjust the vertical airflow to a direction opposite to the horizontal air outlet 112 for horizontal airflow.

[0057] When horizontal airflow is required, the lower air guide plate 140 rotates downward to the fifth position E, which closes the vertical air outlet 111. The upper air guide plate 130 and the lower air guide plate 140 fully or partially open the horizontal air outlet 112, and the airflow is sent out through the horizontal air outlet 112.

[0058] When air needs to be supplied in two directions at the same time, the lower air guide plate 140 remains in the state of opening the vertical air outlet 111, while the air guide plate assembly (upper air guide plate 130 and lower air guide plate 140) fully or partially opens the horizontal air outlet 112, so that the airflow is distributed and delivered through the vertical air outlet 111 and the horizontal air outlet 112 at the same time, thereby achieving simultaneous air supply to multiple areas without increasing the number of units.

[0059] In this mode, the distribution of the two air supply volumes can be controlled by adjusting the opening angle ratio of the horizontal air outlet 112. For example, the horizontal air outlet 112 can be partially opened to ensure that the vertical air supply is prioritized, or it can be fully opened to achieve a balanced air supply effect between the two channels.

[0060] In this embodiment, a vertical air outlet 111 is provided on the bottom surface of the air distribution box 100, and a horizontal air outlet 112 is provided on the side end face of the air distribution box 100. A guide vane assembly is rotatably installed at the horizontal air outlet 112. The guide vane assembly can close or open the horizontal air outlet 112, and also close or open the vertical air outlet 111, to achieve air supply in one or two directions. Air can be supplied to the dining room and living room separately or simultaneously by a ducted air conditioner arranged in the area between the dining room and living room. Simultaneously, the limiting post 120 is designed to include a rigid rod 121 and an elastic covering layer 122 covering the rigid rod 121. The rigid rod 121... The structural characteristics of 1 ensure that the air guide plate assembly is not prone to bending or deformation even if the limiting post 120 is long after it comes into contact with the limiting post 120. Furthermore, when the horizontal air outlet 112 is closed, the elastic covering layer 122 of the air guide plate and the limiting post 120 is moderately compressed, achieving a tight and good sealing effect. This avoids condensation and air leakage caused by poor sealing between the air guide plate assembly and the limiting post 120. Moreover, the elastic covering layer 122 is made of elastic materials such as rubber, silicone, and plastic, which can buffer when the limiting post 120 comes into contact with the air guide plate assembly, preventing collision damage between the limiting post 120 and the air guide plate assembly.

[0061] In some implementations, such as Figure 1 As shown, with the horizontal air outlet 112 closed, the ends of the upper air guide plate 130 and the lower air guide plate 140 away from their rotation axes abut against the limiting post 120.

[0062] Specifically, the upper air guide plate 130 is rotatably disposed above the horizontal air outlet 112. After its end away from the rotation axis contacts the limiting post 120, the upper air guide plate 130 can close the area above the limiting post 120 in the horizontal air outlet 112. The lower air guide plate 140 is rotatably disposed below the horizontal air outlet 112. After its end away from the rotation axis contacts the limiting post 120, the lower air guide plate 140 can close the area below the limiting post 120 in the horizontal air outlet 112. When the upper air guide plate 130 and the lower air guide plate 140 simultaneously contact the limiting post 120, the upper air guide plate 130 and the lower air guide plate 140 can close the entire horizontal air outlet 112.

[0063] The lower air guide plate 140 is connected to the housing of the air distribution box 100 located below the horizontal air outlet 112. The horizontal dimension of the vertical air outlet 111 can be smaller than the dimension of the lower air guide plate 140, so that during rotation, the lower air guide plate 140 can selectively close not only the area below the limiting post 120 in the horizontal air outlet 112, but also the vertical air outlet 111, thereby achieving horizontal air supply or downward vertical air supply independently. Of course, if the lower air guide plate 140 does not close the vertical air outlet 111, the upper air guide plate 130 and the lower air guide plate 140 can also achieve simultaneous horizontal and vertical air supply by not closing the horizontal air outlet 112 or only partially closing the horizontal air outlet 112.

[0064] In some implementations, such as Figure 1 As shown, with the horizontal air outlet 112 closed, a gap 150 is formed between the ends of the upper air guide plate 130 and the lower air guide plate 140 that are away from their respective rotation axes. This gap 150 is used to avoid interference or collision between the upper air guide plate 130 and the lower air guide plate 140 during rotation, thereby ensuring the smoothness and reliability of the air guide plate assembly when switching between multiple air supply modes.

[0065] Preferably, the gap 150 has a vertical dimension of 4mm to 6mm. While meeting the anti-interference requirement, it can still achieve effective sealing after the two air guide plates and the elastic covering layer 122 of the limiting post 120 are tightly abutted, preventing condensate leakage or airflow leakage.

[0066] In practical applications, when a user needs to switch from horizontal to vertical airflow mode, or vice versa, the upper air guide plate 130 and the lower air guide plate 140 will rotate sequentially to their respective target positions. During this process, the gap 150 prevents the two air guide plates from colliding with each other on their trajectory. Even when the air guide plates rotate at high speeds or have a certain amount of inertia, mechanical jamming or structural damage can be avoided, thereby extending the service life of the air guide plate assembly and improving the user experience.

[0067] In some implementations, such as Figure 3 As shown, the limiting post 120 is horizontally positioned within the horizontal air outlet 112, with its two ends connected to both sides of the horizontal air outlet 112 in the width direction. That is, the limiting post 120 completely penetrates the entire horizontal air outlet 112 in the width direction. Thus, when the upper air guide plate 130 and the lower air guide plate 140 are fully in contact with the limiting post 120, the upper air guide plate 130, the lower air guide plate 140, and the limiting post 120 together completely seal the entire opening area of ​​the horizontal air outlet 112, effectively blocking airflow through the outlet.

[0068] First, because the limiting post 120 has no breaks in its width direction, the air guide plate assembly can form a continuous sealing line when in contact with the limiting post 120, reducing the risk of air leakage. Second, the two ends of the limiting post 120 are firmly connected to the two side walls of the horizontal air outlet 112, and can withstand the contact pressure from the air guide plate during the opening or closing of the air guide plate. Even if the air guide plate is used under high wind speed or frequent switching conditions, it is not easy to bend or shift. Third, the through-type limiting post structure has a regular shape and is simple to process. During assembly, it only needs to be fixed at both ends, reducing the need for intermediate support structures and thus reducing manufacturing costs.

[0069] Of course, the elastic covering layer 122 covering the limiting post 120 is also set to the same length as the limiting post 120. The elastic covering layer 122 forms a continuous contact surface in the horizontal direction, which is conducive to further improving the sealing effect of the air guide plate and providing buffer when in contact to avoid wear or noise of parts due to hard collision.

[0070] In some implementations, such as Figure 4 and 5 As shown, with the horizontal air outlet 112 closed, the upper air guide plate 130 abuts against the limiting post 120, and the lower air guide plate 140 abuts against the side of the upper air guide plate 130 away from the limiting post 120. In some other embodiments, with the horizontal air outlet 112 closed, the lower air guide plate 140 abuts against the limiting post 120, and the upper air guide plate 130 abuts against the side of the lower air guide plate 140 away from the limiting post 120. The abutment of one of the upper air guide plate 130 and the lower air guide plate 140 against the limiting post 120 primarily serves to limit the position of the air guide plate assembly, and the overlapping and abutting cooperation between the two air guide plates achieves a sealing effect.

[0071] Specifically, one possible implementation is that, with the horizontal air outlet 112 closed, the free end of the upper air guide plate 130 (i.e., the end away from its rotation axis) directly abuts against the surface of the elastic covering layer 122 of the limiting post 120, while the free end of the lower air guide plate 140 abuts against the surface of the upper air guide plate 130 away from the limiting post 120.

[0072] Specifically, another optional implementation is that, with the horizontal air outlet 112 closed, the free end of the lower air guide plate 140 directly abuts against the surface of the elastic covering layer 122 of the limiting post 120, while the free end of the upper air guide plate 130 abuts against the side surface of the lower air guide plate 140 opposite to the limiting post 120. In this structure, the lower air guide plate 140 serves as a direct limiting element, and the upper air guide plate 130 achieves a closed fit through contact with the lower air guide plate 140.

[0073] Regardless of which implementation method is adopted, one of the upper air guide plate 130 and the lower air guide plate 140 directly contacts the limiting post 120 and performs a limiting function, ensuring that the air guide plate can be reliably fixed in the designed position in the closed state, preventing it from deviating from the sealed position due to airflow impact or vibration. At the same time, the other air guide plate forms an overlapping or fitting contact surface with the former in the closed position. This combination of "direct limiting + indirect sealing" can ensure sealing reliability while reducing the number of components, and improve the accuracy and stability of airflow control.

[0074] In addition, since the outer surface of the limiting post 120 is covered with an elastic covering layer 122, the air guide plate that directly contacts the limiting post can obtain flexible buffer when closed, avoiding noise and wear of parts caused by hard collision; and the contact surfaces between the air guide plates are usually surface-to-surface, with high fitting precision and strong sealing, which can effectively reduce air leakage and condensation problems caused by air leakage.

[0075] In some embodiments, when the horizontal air outlet 112 is closed, the vertical dimension of the overlap area 160 between the upper air guide plate 130 and the lower air guide plate 140 is 6-15 mm. The presence of this overlap area 160 ensures a reliable sealing fit between the upper air guide plate 130 and the lower air guide plate 140 in the closed state, thereby effectively preventing air leakage from the gaps between the air guide plates and improving the sealing performance of the horizontal air outlet 112 and the air delivery efficiency of other air outlets.

[0076] Preferably, the dimensions of the overlapping area 160 can be adjusted according to the material elasticity of the air guide plate, the size of the air outlet, and the required sealing effect. A smaller overlapping area (e.g., about 6 mm) can reduce the resistance and friction of the air guide plate during opening and closing while ensuring the sealing effect, facilitating smooth rotation of the air guide plate; while a larger overlapping area (e.g., about 15 mm) can enhance the sealing reliability and reduce sealing leakage problems caused by air pressure fluctuations or long-term use.

[0077] In some implementations, such as Figure 6 As shown, the limiting post 120 includes a first limiting post 123 and a second limiting post 124 horizontally disposed within the horizontal air outlet 112. The first limiting post 123 is connected to one side of the horizontal air outlet 112 in the width direction, and the second limiting post 124 is connected to the other side of the horizontal air outlet 112 in the width direction.

[0078] With this arrangement, the limiting post 120 can form a support and limiting structure on both sides of the horizontal air outlet 112, so that the upper air guide plate 130 and the lower air guide plate 140 can simultaneously abut against the first limiting post 123 and the second limiting post 124 when the horizontal air outlet 112 is closed, thereby achieving reliable sealing of the entire horizontal air outlet.

[0079] Preferably, both the first limiting post 123 and the second limiting post 124 are composed of a rigid rod 121 and an elastic covering layer 122. The rigid rod 121 provides structural support and bending resistance, ensuring that the air guide plate will not bend or deform when it contacts the limiting post. The elastic covering layer 122 provides a buffering effect, reducing noise and avoiding friction damage caused by long-term use when the overlapping area of ​​the upper air guide plate 130 and the lower air guide plate 140 collides.

[0080] In some implementations, such as Figure 7 As shown, the limiting post 120 is horizontally disposed within the horizontal air outlet 112, and the middle part of the limiting post 120 is connected to the upper edge of the horizontal air outlet 112 via a connecting rod 125. In some embodiments, the limiting post 120 is horizontally disposed within the horizontal air outlet 112, and the middle part of the limiting post 120 is connected to the lower edge of the horizontal air outlet 112 via a connecting rod 125. Of course, in some embodiments, the limiting post 120 is horizontally disposed within the horizontal air outlet 112, and the middle part of the limiting post 120 is connected to both the upper and lower edges of the horizontal air outlet 112 via a connecting rod 125.

[0081] Since the rotating connection positions and driving devices of the upper air guide plate 130 and the lower air guide plate 140 are all located on both sides or one side of the horizontal air outlet 112 in the width direction, the two ends of the upper air guide plate 130 and the lower air guide plate 140 overlap tightly in the closed state, while the overlap effect is relatively poor in the middle area because it is farther away from the rotating shaft or driving point. To improve the limiting and sealing effect in the middle area, a limiting post 120 can be set in the middle of the horizontal air outlet in the width direction. The limiting post 120 in the middle position is horizontally set in the middle section of the horizontal air outlet 112, so that the middle area of ​​the upper air guide plate 130 and the lower air guide plate 140 is effectively supported and abutted in the closed state, thereby enhancing the limiting stability and sealing effect of the air guide plate assembly in the entire width direction. With this design, even if the air guide plate is long or the horizontal air outlet is wide, the air guide plate can still be in close contact with the limiting post 120 in the middle, avoiding the occurrence of loosening, air leakage or condensation problems in the middle, while maintaining the reliable service life of the entire air guide plate assembly.

[0082] In some implementations, such as Figure 5 As shown, both the upper air guide plate 130 and the lower air guide plate 140 have a reinforcing plate 131 inside at the end furthest from their rotation axis. By providing the reinforcing plate 131, when the air guide plate is closed and abuts against the limiting post 120 or when the upper and lower air guide plates overlap, bending, deformation, or sagging of the air guide plate during stress or prolonged use can be effectively prevented, thus ensuring the sealing reliability of the air guide plate assembly in the closed state of the horizontal air outlet 112. This design not only improves the structural stability of the air guide plate but also enhances the sealing effect of the horizontal air outlet under different air supply modes, preventing air leakage or condensation.

[0083] In some embodiments, the air guide plate has a multi-layered assembly structure, with the outer layer consisting of a flexible material layer and a plastic shell. When the upper air guide plate 130 and the lower air guide plate 140 form an overlapping area 160, the contact surface of at least one air guide plate within the overlapping area 160 is a flexible material layer. The flexible material layer can be made of rubber, silicone, or other elastic materials, capable of producing slight compression deformation when the air guide plates are stacked together, thereby filling the gaps between the air guide plates and improving the sealing effect. This design ensures good sealing performance of the air guide plates within the overlapping area 160 under contact pressure, while also buffering collisions, reducing friction and noise between the air guide plates, extending the service life of the air guide plates, and effectively preventing scratches or damage caused by direct contact of rigid materials.

[0084] Secondly, this application provides a ducted air conditioner. The main structure of the ducted air conditioner includes a fan system 200, a heat exchange system 300, and an air distribution box 100. The heat exchange system 300 is connected to the fan system 200. The air distribution box 100 is located on the air outlet side of the heat exchange system 300. A control system can also be installed in the ducted air conditioner.

[0085] It should be noted that the fan system 200 typically includes a volute, motor, fan blades, etc. The fan system 200 has no external casing to increase the return air channel area and improve heat exchange efficiency. The control system is usually an electrical control box or electrical control enclosure, which communicates with the fan system 200, the heat exchange system 300, and the air distribution box 100. The open side of the air distribution box 100 (i.e., the side opposite to the horizontal air outlet 112) is connected to the heat exchange system 300.

[0086] The heat exchange system 300 includes a casing 310, a V-shaped heat exchanger, and a drip tray 320. An air duct is formed within the casing 310, with air inlets and outlets on both sides. A fan is configured to introduce airflow into the air duct from the air inlets, and the fan's outlet is connected to the air inlet of the air duct. The fan is preferably a cross-flow fan or a centrifugal fan, with stable output speed and moderate airflow. The V-shaped heat exchanger includes a first heat exchanger 330 and a second heat exchanger 340 arranged vertically. The drip tray 320 is located below the V-shaped heat exchanger. The shape of the drip tray 320 can be rectangular, trapezoidal, or arc-shaped depending on the outline of the heat exchanger, and its lower part is provided with a drain outlet or drain pipe interface to guide the collected condensate to the drainage system. The drip tray 320 is located in the lower region of the V-shaped heat exchanger and is used to directly collect the condensate dripping from the V-shaped heat exchanger.

[0087] During the cooling or dehumidification mode of air conditioning operation, condensation easily forms on the surface of the V-shaped heat exchanger due to temperature reduction. Some of the condensation will naturally drip down the pipe wall, and this portion can be directly collected and discharged by the drip tray 320. However, another portion of the condensation is passively carried away from the heat exchanger surface by the airflow impact, and is easily carried to the air outlet area of ​​the V-shaped heat exchanger, where it will accumulate within the unit over time. To collect and discharge this type of condensation, in some embodiments, when the lower air guide plate 140 rotates to close the vertical air outlet 111, the free end of the lower air guide plate 140 overlaps the drip tray 320, and the height of the lower air guide plate 140 gradually decreases along the direction gradually approaching the drip tray 320, forming an effective condensation guiding surface. Condensate dripping from the V-shaped heat exchanger or splashing onto the outlet side by strong airflow falls onto the lower air guide plate 140 under gravity, flows along the lower air guide plate 140, and is eventually guided into the water receiving tray 320.

[0088] This application embodiment also provides a control method for a ducted air conditioner, applied to the ducted air conditioner provided in this application embodiment. The control method includes: controlling the position of the air guide plate assembly according to the operating mode of the ducted air conditioner, so as to realize the opening and closing or the opening degree adjustment of the horizontal air outlet 112 and the vertical air outlet 111.

[0089] Optionally, the control method includes: controlling the upper air guide plate 130 to rotate between the first position A and the second position B, and controlling the lower air guide plate 140 to rotate between the third position C, the fourth position D and the fifth position E, according to the operating mode of the ducted air machine and the distance between the ducted air machine and the personnel in the space it handles; wherein the operating mode of the ducted air machine includes a personnel avoidance mode and a personnel blowing mode.

[0090] For example, both the upper air guide plate 130 and the lower air guide plate 140 are constructed as flat plate structures; the upper air guide plate 130 and the lower air guide plate 140 rotate independently of each other;

[0091] For example, when both the upper air guide plate 130 and the lower air guide plate 140 are kept closed at the horizontal air outlet 112, the upper air guide plate 130 and the lower air guide plate 140 together form the air outlet area of ​​the horizontal air outlet 112.

[0092] For example, the second position B can be used to at least partially open the upper region of the horizontal air outlet 112, or the second position B can be used to fully open the upper region of the horizontal air outlet 112.

[0093] In this disclosure, flexible adjustment of long-distance and short-distance air supply can be achieved according to actual conditions. The control method provided in this disclosure controls the upper air guide plate 130 to rotate between the first position A and the second position B, and controls the lower air guide plate 140 to rotate between the third position C, the fourth position D, and the fifth position E, based on the operating mode of the ducted air conditioner and the distance between the ducted air conditioner and the personnel in the space it serves. The operating modes of the ducted air conditioner include a personnel avoidance mode and a personnel blowing mode. Thus, the opening and closing positions of the upper air guide plate 130 and the lower air guide plate 140 can be controlled according to different scenario requirements to adjust the size of the opening of the horizontal air outlet 112 and the vertical air outlet 111. By controlling the rotation and opening / closing positions of the upper air guide plate 130 and the lower air guide plate 140, the airflow direction and speed can be changed to achieve different air outlet methods, adapting to various user scenarios. Furthermore, it can increase the air supply range, improve cooling and heating effects, and enhance the user experience.

[0094] Specifically, this ducted air conditioner features a horizontal air outlet 112 (front) and a vertical air outlet 111 (lower), along with a rotatable upper guide plate 130 and lower guide plate 140, creating a flexible and variable air outlet channel. The upper guide plate 130 controls the opening and closing of the upper area of ​​the horizontal air outlet 112, while the lower guide plate 140 can switch between the lower part of the horizontal air outlet 112 and the vertical air outlet 111, enriching the air outlet path options and providing a hardware foundation for precise air delivery. Furthermore, based on the dual-dimensional control of the air guide vanes (operating mode (avoiding people / blowing people) + personnel distance), an intelligent air delivery logic is constructed: In the blowing people mode, the opening of the upper air guide vane 130° (A / B switching) and the position of the lower air guide vane 140° (C / D / E adaptation) are dynamically adjusted according to the personnel distance, allowing cold / hot air to accurately reach the personnel activity area and enhance the comfort experience; in the avoidance people mode, the upper air guide vane 130° is blocked at the top, and the lower air guide vane 140° is adapted and positioned (e.g., C blocks the lower part of the horizontal air outlet 112 or E blocks the vertical air outlet 111), forcibly changing the airflow direction to avoid direct airflow to the human body and causing discomfort. The coordinated control of the dual air guide vanes allows the ductwork to adapt to various spatial scenarios (such as close-range rest, long-distance whole-house air delivery, etc.), significantly improving the accuracy of air delivery and user experience, and achieving a technological breakthrough of "on-demand air delivery and intelligent interference avoidance".

[0095] One application scenario to consider:

[0096] Based on the operating mode of the ducted air conditioner and the distance between the ducted air conditioner and the personnel in the space it serves, the upper air guide plate 130 is controlled to rotate between the first position A and the second position B, and the lower air guide plate 140 is controlled to rotate between the third position C, the fourth position D, and the fifth position E, including:

[0097] When the ducted air conditioner is in the personnel avoidance mode and the distance between personnel is greater than or equal to the set distance, control the upper air guide plate 130 to rotate to the second position B, and control the lower air guide plate 140 to rotate to the fourth position D.

[0098] Driven by this control logic, the upper air guide plate 130 opens the upper part of the horizontal air outlet 112, and the lower air guide plate 140 is in the fourth position D (the transition state connecting the lower part of the horizontal air outlet 112 and the vertical air outlet 111), allowing the airflow delivered by the fan to form a more reasonable flow path. The airflow can be guided from the upper part of the horizontal air outlet 112 through the lower air guide plate 140 to diffuse to a wider area, promoting air circulation in the space and accelerating temperature control. Especially in large spaces where rapid temperature equalization is required, this combination of air guide plate positions allows hot and cold air to cover the space more efficiently, shortening the temperature adjustment time and enhancing the energy efficiency of air conditioning operation.

[0099] Consider application scenario two:

[0100] Based on the operating mode of the ducted air conditioner and the distance between the ducted air conditioner and the personnel in the space it serves, the upper air guide plate 130 is controlled to rotate between the first position A and the second position B, and the lower air guide plate 140 is controlled to rotate between the third position C, the fourth position D, and the fifth position E, including:

[0101] When the ducted air conditioner is in the personnel avoidance mode and the distance between personnel is less than the set distance, control the upper air guide plate 130 to rotate to the second position B, and control the lower air guide plate 140 to rotate to the fourth position D.

[0102] Driven by this control logic, the upper air guide plate 130 opens the upper air outlet, and the lower air guide plate 140 is positioned at the fourth position D, reshaping the airflow direction within the unit. The airflow can diffuse through the upper part of the horizontal air outlet 112, and then be guided by the lower air guide plate 140 to flow towards the lower part of the space or the area associated with the vertical air outlet 111, forming a composite air supply path of "upper diffusion + lower guidance". Compared with the traditional single air guide mode, this path can break the limitation of direct airflow, promote spatial air circulation, quickly equalize the temperature in close-range scenarios, improve temperature control efficiency, and ensure the gentleness of airflow around the human body, thus optimizing the user experience. This control strategy deepens the function for the specific scenario of "close-range avoidance of people", expanding the intelligent adaptation boundary of the ducted air conditioner. When users are engaged in close-range activities (such as when the air conditioner is running close to the user while working at a desk), or are sensitive to airflow (such as in the environment of the elderly or patients), this method can precisely adjust the air conditioner through the air guide plate, allowing the air conditioner to actively adapt to the human body position and needs without the need for frequent manual adjustments. This not only strengthens the product's intelligent interference avoidance attributes, but also enhances the product's competitiveness in diverse close-range scenarios such as home and office, providing users with more refined and user-friendly air conditioning solutions and helping the product highlight its differentiated advantages in the market.

[0103] Consider application scenario three:

[0104] Based on the operating mode of the ducted air conditioner and the distance between the ducted air conditioner and the personnel in the space it serves, the upper air guide plate 130 is controlled to rotate between the first position A and the second position B, and the lower air guide plate 140 is controlled to rotate between the third position C, the fourth position D, and the fifth position E, including:

[0105] When the air duct unit is in the air blowing mode and the distance between people is greater than or equal to the set distance, control the upper air guide plate 130 to rotate to the second position B, and control the lower air guide plate 140 to rotate to the fifth position E.

[0106] In this control logic, the upper air guide plate 130 opens to ensure airflow in the upper area, while the lower air guide plate 140 blocks the vertical air outlet 111 to reduce airflow diversion loss. This concentrates the airflow output by the fan from the upper part of the horizontal air outlet 112, significantly improving the air supply pressure and range. Combined with the guiding effect of the upper air guide plate 130 at the second position B, the airflow can form a better diffusion angle and air delivery trajectory, quickly covering a long-distance space and accelerating the temperature equalization of the space. Compared with the multi-outlet air supply method, this centralized air supply mode is more energy efficient in long-distance scenarios, reducing unnecessary energy loss and improving the economy and practicality of air conditioning operation. It can be precisely controlled for specific scenarios of "blowing people mode + long distance", further expanding the intelligent adaptation boundary of ducted air conditioners. When users are engaged in long-distance activities (such as resting on the sofa in the living room or working in the back row of the conference room), there is no need to manually adjust the air guide angle; the air conditioner can automatically achieve directional air supply through the combination of air guide plate positions. This design enhances the product's responsiveness to different distances and usage scenarios, upgrading the air conditioner from a "passive temperature control" device to an intelligent device that "actively adapts to needs." This improves the user experience while highlighting the product's technological advantages in air delivery accuracy and scenario compatibility, thus enhancing its market competitiveness.

[0107] Consider application scenario four:

[0108] Based on the operating mode of the ducted air conditioner and the distance between the ducted air conditioner and the personnel in the space it serves, the upper air guide plate 130 is controlled to rotate between the first position A and the second position B, and the lower air guide plate 140 is controlled to rotate between the third position C, the fourth position D, and the fifth position E, including:

[0109] When the air duct unit is in the air blowing mode and the distance between people is less than the set distance, control the upper air guide plate 130 to rotate to the first position A, and control the lower air guide plate 140 to rotate to the third position C.

[0110] In this way, under this control logic, the upper air guide plate 130 blocks the upper part of the horizontal air outlet 112, and the lower air guide plate 140 blocks the lower part of the horizontal air outlet 112, forcing the airflow to be directed out from the vertical air outlet 111, thus changing the airflow direction of traditional close-range air supply. The vertical air outlet 111 is located on the lower side of the housing 110, allowing the delivered airflow to diffuse along the lower part of the space, reducing direct blowing on the head and face of the human body, and reducing discomfort caused by strong airflow at close range (such as dry skin, cold joints, etc.). At the same time, concentrated air supply from the vertical air outlet 111 allows the airflow to more evenly cover the middle and lower parts of the human body, improving physical comfort while enhancing the safety of using the air conditioner at close range. This method can be specifically adjusted for the "blowing mode + close range" sub-scenario, further improving the scenario adaptation system of ducted air conditioners. When users are in close proximity (such as lying in bed before sleep or sitting at a desk for extended periods), the air conditioner can automatically detect the distance to the person and adjust the position of the air deflector, providing an appropriate airflow mode without manual intervention from the user. This design improves the product's response speed and control accuracy for different distance scenarios, allowing the air conditioner to dynamically optimize the airflow strategy based on the person's location. This enhances the product's intelligent attributes and user experience, highlighting its technological advantages and market competitiveness in close-range airflow scenarios.

[0111] Considering that ducted air conditioners can have a new fan system 200 fan speed control scheme, the control method provided in this disclosure embodiment includes:

[0112] The fan speed is controlled based on the duct air conditioner's operating mode, ambient temperature, personnel temperature, and personnel distance.

[0113] In this way, by combining the operating mode (avoiding people / blowing people), ambient temperature, personnel temperature, and personnel distance to adjust the fan speed of the 200-type fan system, precise air supply regulation with multi-dimensional parameter linkage can be achieved. In the blowing people mode, if the difference between the ambient temperature and the personnel temperature is large and the personnel are close, the fan speed can be increased to enhance the air supply intensity and quickly reduce the temperature difference; in the avoid people mode or when the personnel are far away, the fan speed is dynamically reduced based on the ambient and personnel temperatures, which can maintain the space temperature control requirements while reducing airflow disturbance and energy consumption, making the operation of the 200-type fan system more adaptable to the actual scenario requirements, improving the overall regulation efficiency and user experience.

[0114] Considering that a ducted air conditioner can have one of the specific control schemes for the fan speed in a new fan system 200, the control method provided in this embodiment controls the fan speed in the fan system 200 according to the operating mode of the ducted air conditioner, ambient temperature, personnel temperature, and personnel distance, including:

[0115] Under any of the following sub-conditions: the operating mode of the ducted air conditioner, ambient temperature, personnel temperature, and personnel distance meet the first set conditions, the speed of the fan in the fan system 200 is increased.

[0116] The first set of conditions includes:

[0117] The first sub-condition is that the air duct unit is in the human avoidance mode, and the temperature difference between the personnel and the ambient temperature is less than the set temperature, and the distance between the personnel is greater than or equal to the set distance.

[0118] The second sub-condition is that the air duct unit is in the human avoidance mode, and the temperature difference between the personnel and the ambient temperature is less than the set temperature, and the distance between the personnel is less than the set distance.

[0119] The third sub-condition is that the air duct unit is in the air blowing mode, the temperature difference between the person and the ambient temperature is less than the set temperature, and the distance between the people is greater than or equal to the set distance.

[0120] The fourth sub-condition is that the air duct unit is in the air blowing mode, the temperature difference between the personnel and the ambient temperature is less than the set temperature, and the distance between the personnel is less than the set distance.

[0121] In this way, by increasing the fan speed in the fan system 200 under any sub-condition of the first set condition, the temperature control requirement of the core scenario of "the temperature difference between personnel temperature and ambient temperature being less than the set temperature" can be specifically addressed. Whether in the avoidance mode or the blowing mode, regardless of the distance between personnel, when the temperature difference is small, increasing the fan speed in the fan system 200 can enhance the efficiency of air intake and exhaust, accelerate the air conditioning's circulation and regulation of the air in the space, and push the personnel temperature and ambient temperature closer to the target temperature difference. This avoids the problem of insignificant temperature control effect due to insufficient temperature difference, and provides power support for rapid temperature control in different modes and distance scenarios.

[0122] Furthermore, this control logic achieves refined dynamic adjustment by linking multiple parameters such as operating mode, temperature difference, and personnel distance with the fan speed of the 200-speed fan system. In the avoidance mode, increasing the speed enhances airflow diffusion, ensuring efficient heat exchange in both distant and nearby spaces. In the people-oriented mode, increasing the speed strengthens the airflow, allowing it to act more precisely and quickly on the personnel area. This multi-scenario adaptable speed control strategy improves the air conditioner's temperature control response speed when the temperature difference is small, while also ensuring the airflow effect in different modes, further optimizing the product's intelligent adjustment performance and user experience.

[0123] Considering that a ducted air conditioner can have one of the specific control schemes for the fan speed in a new fan system 200, the control method provided in this embodiment controls the fan speed in the fan system 200 according to the operating mode of the ducted air conditioner, ambient temperature, personnel temperature, and personnel distance, including:

[0124] Under any of the following sub-conditions: the operating mode of the ducted air conditioner, ambient temperature, personnel temperature, and personnel distance meet the second set conditions, the speed of the fan in the fan system 200 is reduced.

[0125] The second set of conditions includes:

[0126] The fifth sub-condition is that the air duct unit is in the human avoidance mode, and the temperature difference between the personnel temperature and the ambient temperature is greater than or equal to the set temperature, and the personnel distance is greater than or equal to the set distance.

[0127] The sixth sub-condition is that the air duct unit is in the human avoidance mode, and the temperature difference between the personnel and the ambient temperature is greater than or equal to the set temperature, and the distance between the personnel is less than the set distance.

[0128] The seventh sub-condition is that the air duct unit is in the air blowing mode, and the temperature difference between the personnel and the ambient temperature is greater than or equal to the set temperature, and the distance between the personnel is greater than or equal to the set distance.

[0129] The eighth sub-condition is that the air duct unit is in the air blowing mode, the temperature difference between the personnel and the ambient temperature is greater than or equal to the set temperature, and the distance between the personnel is less than the set distance.

[0130] In this way, by reducing the fan speed in the fan system 200 under any sub-condition of the second set condition, the scenario requirement of "the temperature difference between personnel temperature and ambient temperature being greater than or equal to the set temperature" can be specifically adapted. Regardless of whether it is in the avoidance mode or the blowing mode, and regardless of the distance of personnel, when the temperature difference has reached the target range, reducing the fan speed in the fan system 200 can reduce unnecessary energy consumption and airflow disturbance. In the avoidance mode, it avoids the strong airflow diffusion from affecting the tranquility of the space, and in the blowing mode, it prevents excessive airflow from causing discomfort to the human body. Through multi-parameter linkage speed control, a balance between stable temperature control effect and energy saving and comfort is achieved, further optimizing the product's operating energy efficiency and user experience.

[0131] The ducted air conditioner, considering the specific rotation scheme of the upper air guide plate 130 and the lower air guide plate 140, in the ducted air conditioner provided in this embodiment, the upper air guide plate 130 is rotatably connected to the housing 110 via a first rotating shaft, and the lower air guide plate 140 is rotatably connected to the housing 110 via a second rotating shaft. This provides a structural basis for the precise rotation and stable positioning of the air guide plates. The first rotating shaft supports the upper air guide plate 130 to flexibly switch between the first position A and the second position B, realizing the reliable opening and closing of the upper area of ​​the horizontal air outlet 112; the second rotating shaft ensures that the lower air guide plate 140 rotates smoothly between the third, fourth, and fifth positions, accurately completing the control and switching between the lower area of ​​the horizontal air outlet 112 and the vertical air outlet 111. This rotating shaft connection structure ensures the stability and controllability of the air guide plate rotation, providing reliable mechanical support for the coordinated control of the air guide plate based on the operating mode and personnel distance, further improving the accuracy and scenario adaptability of the air duct unit's air outlet control, and enhancing the feasibility and effectiveness of the overall air supply solution.

[0132] Considering the specific driving scheme of the first rotating shaft, in the duct air conditioner provided in this embodiment, the duct air conditioner includes a first drive motor, which is driven and connected to the first rotating shaft, and is used to drive the first rotating shaft to rotate to different preset angles under different conditions, so that the upper air guide plate 130 stops at the first position A or the second position B.

[0133] This design, where the first drive motor is connected to the first rotating shaft, provides the power guarantee for the precise positioning and automated control of the upper air guide plate 130. The first drive motor can rotate the first rotating shaft to different preset angles according to control commands, allowing the upper air guide plate 130 to reliably remain at either position A (blocking the upper area of ​​the horizontal air outlet 112) or position B (opening the upper area of ​​the horizontal air outlet 112), replacing the limitations of traditional manual adjustment or non-drive positioning. This drive scheme ensures the rapid response and precise switching of the upper air guide plate 130 under different operating modes and personnel distance scenarios, enhances the synchronization and reliability of the linkage control between the upper air guide plate 130 and the lower air guide plate 140, provides core power support for the intelligent and automated adjustment of the air guide plates in the overall air supply scheme, and further improves the accuracy and efficiency of the duct air conditioner's air outlet control.

[0134] Considering the specific driving scheme of the second rotating shaft, in the duct air conditioner provided in this embodiment, the duct air conditioner includes a second drive motor, which is driven and connected to the second rotating shaft, and is used to drive the second rotating shaft to rotate to different preset angles under different conditions, so that the lower air guide plate 140 stops at the third position C, the fourth position D or the fifth position E.

[0135] This design, where the second drive motor is connected to the second rotating shaft, provides reliable power support for the precise multi-position positioning and automated control of the lower air guide plate 140. The second drive motor can rotate the second rotating shaft to different preset angles according to control commands, allowing the lower air guide plate 140 to stably remain at the third position C (blocking the lower area of ​​the horizontal air outlet 112), the fourth position D (transition position), or the fifth position E (blocking the vertical air outlet 111), overcoming the limitations of traditional air guide plate adjustment methods. This drive scheme ensures the flexible switching and precise positioning of the lower air guide plate 140 under different operating modes and personnel distance scenarios, enhancing its coordination with the upper air guide plate 130's linkage control. It provides crucial drive support for the overall air supply scheme, enabling the air guide plate to dynamically adapt its airflow path according to the scenario, further improving the flexibility, reliability, and intelligence level of the duct air conditioner's airflow control.

[0136] Considering the use of duct air conditioners to detect ambient temperature, personnel temperature, and personnel distance, the duct air conditioner provided in this embodiment includes a temperature sensor and a human body sensor. The temperature sensor is used to monitor the ambient temperature in real time, and the human body sensor is used to monitor the distance of personnel relative to the duct air conditioner and personnel temperature in real time.

[0137] This design, with its real-time monitoring of ambient temperature by temperature sensors and simultaneous acquisition of relative distance and temperature of personnel by human body sensors, provides a precise foundation for scene parameter input in the overall control scheme. The temperature sensor ensures the real-time accuracy of ambient temperature data, while the human body sensor enables simultaneous monitoring of personnel distance (far / near) and temperature. Together, they form the core data support for switching operating modes, adjusting the position of the air guide vanes, and regulating the fan speed in the 200-level fan system. This sensing and detection scheme allows the ducted air conditioner to dynamically perceive the spatial environment and personnel status, providing reliable parameter data for functions such as "person avoidance / blowing mode adaptation," "multi-position linkage of air guide vanes," and "dynamic adjustment of fan speed in the 200-level fan system." This ensures that various control strategies accurately respond to actual scene requirements, enhancing the scientific nature and effectiveness of the ducted air conditioner's intelligent air delivery from the perception layer and improving the closed-loop control capability of the overall scheme.

[0138] In summary, to better understand the ducted air conditioning system solution disclosed herein, the following implementation method is provided for supplementary description:

[0139] Ductless Air Conditioner Reference Figure 8 Both the upper air guide plate 130 and the lower air guide plate 140 are fully open, allowing air to be blown out from the front for long-distance air delivery. The air delivery distance can be adjusted as follows: ① Adjusting the fan speed in the fan system 200 individually; ② Adjusting the opening angle of the upper air guide plate 130 individually; ③ Adjusting both the fan speed in the fan system 200 and the opening angle of the upper air guide plate 130 simultaneously.

[0140] refer to Figure 9 Both the upper air guide plate 130 and the lower air guide plate 140 are fully closed, and the air blows out from the bottom, achieving downward air delivery. The air delivery distance can be adjusted by individually adjusting the fan speed in the fan system 200.

[0141] refer to Figure 10 With the upper air guide plate 130 fully open and the lower air guide plate 140 partially open, air is simultaneously blown out from both the front and lower sides, achieving mid-distance circular airflow, rapid temperature adjustment, and improved comfort. Similarly, the airflow strength can be adjusted as follows: ① Individually adjust the fan speed in the fan system 200; ② Individually adjust the opening angles of the upper air guide plate 130 and the lower air guide plate 140; ③ Simultaneously adjust the fan speed in the fan system 200 and the opening angle of the lower air guide plate 140.

[0142] refer to Figure 11 The upper air guide plate 130 is fully closed, and the lower air guide plate 140 is partially open.

[0143] Based on the independent motion control of the upper air guide plate 130 and the lower air guide plate 140, the unit is equipped with temperature and human body detection devices such as infrared sensors (the sensors can be arranged on the front of the unit or independently placed on the ceiling). According to the position of the person and the temperature difference between the person and the environment, the opening of the upper and lower air guide plates 140 and the fan speed in the fan system 200 are adjusted to meet the usage scenario requirements of the wind blowing on the person or the wind following the person.

[0144] Wind blowing mode:

[0145] ① When personnel are far away and the temperature difference is small, the upper air guide plate 130 and the lower air guide plate 140 are fully open relative to the horizontal air outlet 112, and the fan speed in the fan system 200 increases.

[0146] ② When personnel are far away and the temperature difference is large, the upper air guide plate 130 and the lower air guide plate 140 are fully open relative to the horizontal air outlet 112, and the fan speed in the fan system 200 decreases.

[0147] ③ When personnel are nearby and the temperature difference is small, the upper air guide plate 130 and the lower air guide plate 140 are fully closed relative to the horizontal air outlet 112, and the fan speed in the fan system 200 increases.

[0148] ④ When people are nearby and the temperature difference is large, the upper air guide plate 130 and the lower air guide plate 140 are completely closed relative to the horizontal air outlet 112, and the fan speed in the fan system 200 decreases.

[0149] Wind Avoidance Mode:

[0150] ① When personnel are far away and the temperature difference is small, the upper air guide plate 130 is fully open relative to the horizontal air outlet 112, and the lower air guide plate 140 is half open relative to the horizontal air outlet 112, and the fan speed in the fan system 200 increases.

[0151] ② When personnel are far away and the temperature difference is large, the upper air guide plate 130 is fully open relative to the horizontal air outlet 112, and the lower air guide plate 140 is half open relative to the horizontal air outlet 112, and the fan speed in the fan system 200 decreases.

[0152] ③ When personnel are nearby and the temperature difference is small, the lower air guide plate 140 is fully open relative to the horizontal air outlet 112, and the upper air guide plate 130 is half open relative to the horizontal air outlet 112, and the fan speed in the fan system 200 increases.

[0153] ④ When people are nearby and the temperature difference is large, the lower air guide plate 140 is fully open relative to the horizontal air outlet 112, the upper air guide plate 130 is half open relative to the horizontal air outlet 112, and the fan speed in the fan system 200 decreases.

[0154] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting.
