[0051] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the scope of the present application.

[0052] The following disclosure provides many different embodiments, or examples, for implementing different structures of the present application. For the purpose of simplification, the components and arrangements of the specific examples are described in the following. Of course, they are only examples and are not intended to limit the present application. In addition, the present application can repeatedly refer to reference numerals and / or letters in different examples. Such repetition is for the purpose of simplification and clarity, and does not indicate the relationship between the various embodiments and / or arrangements discussed.

[0053] For the convenience of description, spatial relative terms can be used in the description to describe the relative position relationship or movement of one element or feature with respect to another element or feature as shown in the drawings, such as "inner", "outer", "inboard", "outboard", "under", "below", "on", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the drawings. For example, if the device in the drawing is flipped over or the posture is changed or the movement state is changed, then the directional indications will also change accordingly, for example: the element described as "under" or "below" another element or feature will be oriented as "above" or "above" another element or feature. Therefore, the example term "below" can include both the up and down positions. The device can be additionally oriented (rotated 90 degrees or in other directions) and the spatial relative relationship descriptors used in the description are interpreted accordingly.

[0054] At present, duct units are the mainstream indoor terminal form of central air conditioners because of their beautiful installation and space saving. In particular, the decoration style of the whole air outlet that has become popular in recent years is more simple and elegant, and is deeply favored by young consumer groups. However, at present, conventional duct units have only one air outlet. For some apartment types with a decoration style where the air conditioner is installed on the ceiling between the dining room and the living room, users usually need to install two units, one with an air outlet facing the dining room and one facing the living room, with a return air outlet at the bottom. The overall cost of the unit is high and it is not beautiful. This proposal realizes multiple air supply modes by designing a new type of duct unit and its air outlet components. In particular, it can supply air in two different directions at the same time, meeting user needs, with beautiful installation and high cost. When the horizontal air outlet of the unit uses more than two sealing plates to achieve closing and switching, the air guide plate may be too long and lacks rigidity, resulting in poor sealing, causing condensation and air leakage.

[0055] like Figures 1-11 As shown, in order to solve the above technical problems, the embodiment of the present application provides an air distribution box 100, whose main structure includes a box body 110, a limiting column 120 and an air guide plate assembly, wherein 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 column 120 is arranged in the horizontal air outlet 112, and the limiting column 120 includes the following Figure 2 The rigid rod 121 shown and the elastic covering layer 122 covering the outside of the rigid rod 121; the air guide plate assembly includes an upper air guide plate 130 rotatably provided on the upper side of the horizontal air outlet 112 and a lower air guide plate 140 rotatably provided on the lower side of 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 and cooperates with the limiting column 120, and the lower air guide plate 140 is also used to close or open the vertical air outlet 111.

[0056] like Figures 8-11 As shown, the stop positions of the upper air guide plate 130 during rotation include a first position A and a second position B, and the stop positions of the lower air guide plate 140 during rotation include a third position C, a fourth position D, and a fifth position E. In the first position A, the upper air guide plate 130 blocks the upper area of ​​the horizontal air outlet 112. In the second position B, the upper air guide plate 130 opens the upper area of ​​the horizontal air outlet 112. In the third position C, the lower air guide plate 140 blocks the lower area of ​​the horizontal air outlet 112. In the fifth position E, the lower air guide plate 140 blocks the vertical air outlet 111 and opens the lower area of ​​the horizontal air outlet 112. In the fourth position D, the lower air guide plate 140 is located between the third position C and the fifth position E.

[0057] When air needs to be sent in the vertical direction, the upper air deflector 130 and the lower air deflector 140 are turned to the first position A and the third position C to close the horizontal air outlet 112, the inner side of the air deflector assembly is closely attached to the elastic covering layer 122 of the limiting column 120 extending in the horizontal direction, and the lower air deflector 140 opens the vertical air outlet 111, so that air can be sent out 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 air sent out from the vertical air outlet 111, for example, the air sent out in the vertical direction can be further adjusted to be in the opposite direction of the air sent out from the horizontal air outlet 112 through the sweeping structure to perform horizontal air sending.

[0058] When air needs to be sent in the horizontal direction, the lower air deflector 140 is rotated downward to the fifth position E to close the vertical air outlet 111, and the upper air deflector 130 and the lower air deflector 140 are fully or partially opened to the horizontal air outlet 112, so that air is sent out through the horizontal air outlet 112.

[0059] When air needs to be sent in two directions at the same time, the lower air deflector 140 is kept in the state of opening the vertical air outlet 111, and the air deflector assembly (the upper air deflector 130 and the lower air deflector 140) is fully or partially opened to the horizontal air outlet 112, so that air is simultaneously distributed and sent out through the vertical air outlet 111 and the horizontal air outlet 112, thereby realizing multi-area simultaneous air sending without increasing the number of units.

[0060] In this mode, the distribution of the air sending amount of the two routes can be controlled by adjusting the opening angle ratio of the horizontal air outlet 112, for example, the horizontal air outlet 112 is partially opened to ensure that the vertical air sending amount is given priority, or it is fully opened to obtain the effect of balanced air sending of the two routes.

[0061] By the present embodiment, the vertical air outlet 111 is arranged on the bottom surface of the air distribution box 100, the horizontal air outlet 112 is arranged on the side end surface of the air distribution box 100, and the air deflector assembly is arranged to rotate at the horizontal air outlet 112, so that the horizontal air outlet 112 and the vertical air outlet 111 can be closed or opened by the air deflector assembly, air supply in one direction or two directions is realized, and the air duct unit arranged in the area between the dining room and the living room can supply air to the dining room and the living room respectively or simultaneously; meanwhile, the limiting column 120 is designed to include a rigid rod 121 and an elastic coating layer 122 coated outside the rigid rod 121, the structural characteristics of the rigid rod 121 are used to make the air deflector assembly not easy to bend and deform even if the length of the limiting column 120 is relatively long after abutting and contacting the limiting column 120, and in the closed state of the horizontal air outlet 112, the air deflector and the elastic coating layer 122 of the limiting column 120 are moderately compressed to realize good sealing effect of close fitting, avoid condensation and air leakage caused by poor sealing between the air deflector assembly and the limiting column 120, and the elastic coating layer 122 is made of elastic materials such as rubber, silica gel and plastic, which can buffer when the limiting column 120 contacts the air deflector assembly, and avoid collision damage between the limiting column 120 and the air deflector assembly.

[0062] In some embodiments, as shown in FIG. 1, the upper air deflector 130 and the lower air deflector 140 are arranged to abut against the limiting column 120 at the end away from the rotation axis in the state of closing the horizontal air outlet 112. Figure 1

[0063] Specifically, the upper air deflector 130 is rotatably arranged above the horizontal air outlet 112, and after the end away from the rotation axis of the upper air deflector 130 contacts the limiting column 120, the upper air deflector 130 can close the area above the limiting column 120 in the horizontal air outlet 112; the lower air deflector 140 is rotatably arranged below the horizontal air outlet 112, and after the end away from the rotation axis of the lower air deflector 140 contacts the limiting column 120, the lower air deflector 140 can close the area below the limiting column 120 in the horizontal air outlet 112; when the upper air deflector 130 and the lower air deflector 140 contact the limiting column 120 at the same time, the upper air deflector 130 and the lower air deflector 140 can close the entire horizontal air outlet 112.

[0064] ​The lower air guide plate 140 is connected to the shell of the air distribution box 100 below the horizontal air outlet 112, and the horizontal size of the vertical air outlet 111 can be smaller than the size of the lower air guide plate 140, so that during the rotation of the lower air guide plate 140, not only can the area below the limit column 120 in the horizontal air outlet 112 be closed, but the vertical air outlet 111 can also be closed, thereby achieving horizontal air supply alone or downward vertical air supply. Of course, when 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 do not close the horizontal air outlet 112 or only partially close the horizontal air outlet 112, that is, simultaneous horizontal and vertical air outlets can be achieved.

[0065] In some embodiments, as Figure 1 As shown, when the horizontal air outlet 112 is 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 rotation axes. The 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.

[0066] Preferably, the size of the gap 150 in the vertical direction is 4 mm to 6 mm. While meeting the anti-interference requirements, it can still achieve effective sealing after the two air guide plates are tightly abutted against the elastic covering layer 122 of the limiting column 120 to prevent condensation water leakage or air flow leakage.

[0067] In actual use, when the user needs to switch from horizontal to vertical airflow mode, or vice versa, the upper air deflector 130 and the lower air deflector 140 will rotate to their respective target positions. During this process, the presence of the gap 150 prevents the two air deflectors from colliding with each other along their trajectory. Even when the air deflectors 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 deflector assembly and improving the operating experience.

[0068] In some embodiments, as Figure 3 As shown, the limiting post 120 is horizontally disposed within the horizontal air outlet 112, with both ends of the limiting post 120 respectively connected to both sides in the width direction of the horizontal air outlet 112. That is, the limiting post 120 completely penetrates the entire horizontal air outlet 112 in the width direction. In this way, when the upper air guide plate 130 and the lower air guide plate 140 are completely in contact with the limiting post 120, the upper air guide plate 130, the lower air guide plate 140 and the limiting post 120 can completely seal the entire opening area of ​​the horizontal air outlet 112, thereby effectively blocking airflow through the air outlet.

[0069] First, since the limiting column 120 has no breakpoints in the width direction, the air guide plate assembly can form a continuous sealing line when in contact with the limiting column 120, reducing the risk of air leakage. Secondly, the two ends of the limiting column 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 process 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 displace. Thirdly, the through-type limiting column structure has a regular shape and is simple to process. It only needs to be fixed at both ends during assembly, reducing the need for an intermediate support structure, thereby reducing manufacturing costs.

[0070] Of course, the elastic covering layer 122 covering the outer surface of the limiting column 120 is also set to be the same length as the limiting column 120. The elastic covering layer 122 forms a continuous contact surface in the horizontal direction, which is beneficial to further improve the fitting and sealing effect of the air guide plate, and provide buffering during contact to avoid wear or noise of parts due to hard collision.

[0071] In some embodiments, as Figure 4 and 5 As shown, when the horizontal air outlet 112 is 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 facing away from the limiting post 120. In other embodiments, when the horizontal air outlet 112 is 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 facing 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 mainly serves to limit the position of the air guide plate assembly, and the overlapping and abutting cooperation between the two air guide plates is used to achieve a sealing effect.

[0072] Specifically, an optional implementation method is that when the horizontal air outlet 112 is 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 column 120, and the free end of the lower air guide plate 140 abuts against the side surface of the upper air guide plate 130 facing away from the limiting column 120.

[0073] Specifically, another optional implementation is that, when the horizontal air outlet 112 is 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 column 120, while the free end of the upper air guide plate 130 abuts against the surface of the side of the lower air guide plate 140 facing away from the limiting column 120. In this structure, the lower air guide plate 140 directly limits the position, and the upper air guide plate 130 achieves a closed fit through contact with the lower air guide plate 140.

[0074] No matter which of the above embodiments is adopted, one of the upper air deflector 130 and the lower air deflector 140 directly contacts the limiting column 120 and bears the limiting effect, ensuring that the air deflector can be reliably fixed at the designed position in the closed state and preventing deviation from the sealing position due to air flow impact or vibration. Meanwhile, the other air deflector forms a contact surface with the former in the closed position, and the combination of "direct limiting + indirect sealing" can ensure sealing reliability while reducing the number of components, improving the accuracy and stability of air flow control.

[0075] In addition, since the limiting column 120 is coated with an elastic coating layer 122, the air deflector directly contacting the limiting column can obtain flexible buffering when closed, avoiding noise and part wear caused by hard collision; and the contact surface between the air deflectors is usually surface fitting, with high matching precision and strong sealing, which can effectively reduce air leakage and condensation problems caused by air leakage.

[0076] In some embodiments, in the state of closing the horizontal air outlet 112, the size of the overlapping area 160 of the upper air deflector 130 and the lower air deflector 140 in the vertical direction is 6-15 mm. The existence of the overlapping area 160 can ensure that the upper air deflector 130 and the lower air deflector 140 form a reliable sealing fit in the closed state, thereby effectively preventing air from leaking from the gap between the air deflectors and improving the sealing performance of the horizontal air outlet 112 and the air supply efficiency of other air outlets.

[0077] Preferably, the size of the above-mentioned overlapping area 160 can be adjusted according to the material elasticity of the air deflector, 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 deflector during opening and closing while ensuring the sealing effect, facilitating smooth rotation of the air deflector; while a larger overlapping area (e.g., about 15 mm) can enhance the sealing reliability and reduce the problem of sealing leakage caused by air pressure fluctuations or long-term use.

[0078] In some embodiments, as shown in Figure 6 The limiting column 120 includes a first limiting column 123 and a second limiting column 124 arranged horizontally in the horizontal air outlet 112, the first limiting column 123 is connected to one side of the horizontal air outlet 112 in the width direction, and the second limiting column 124 is connected to the other side of the horizontal air outlet 112 in the width direction.

[0079] Through this arrangement, the limiting column 120 can form a supporting and limiting structure on both sides of the horizontal air outlet 112, so that the upper air deflector 130 and the lower air deflector 140 can simultaneously abut against the first limiting column 123 and the second limiting column 124 when closing the horizontal air outlet 112, thereby achieving reliable closure of the entire horizontal air outlet.

[0080] Preferably, the first limiting column 123 and the second limiting column 124 are both composed of a rigid rod 121 and an elastic covering layer 122. The rigid rod 121 provides structural support and bending resistance to ensure that the air guide plate will not bend or deform when it contacts the limiting column; the elastic covering layer 122 provides a buffering effect to reduce noise in the overlapping area of ​​the upper air guide plate 130 and the lower air guide plate 140 during collision and avoid friction damage caused by long-term use.

[0081] In some embodiments, as Figure 7 As shown, the limiting post 120 is horizontally arranged in the horizontal air outlet 112, and the middle portion 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 arranged in the horizontal air outlet 112, and the middle portion 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 arranged in the horizontal air outlet 112, and the middle portion 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.

[0082] Since the rotation connection positions and drive devices of the upper air guide plate 130 and the lower air guide plate 140 are arranged on both sides or one side of the width direction of the horizontal air outlet 112, the two ends of the width direction are closely superimposed on each other in the closed state, while the central area is relatively far away from the rotation axis or drive point, and the superposition effect is relatively poor. In order to improve the limiting and sealing effect of the central area, a limiting column 120 can be set in the middle of the width direction of the horizontal air outlet. The limiting column 120 in the central position is horizontally arranged in the middle section of the horizontal air outlet 112, so that the upper air guide plate 130 and the lower air guide plate 140 are effectively supported and abutted in the central area in the closed state, thereby enhancing the limiting stability and sealing effect of the air guide plate assembly in the entire width direction. Through 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 column 120 in the middle, avoiding the occurrence of looseness, air leakage or condensation problems in the middle, while maintaining the reliable service life of the entire air guide plate assembly.

[0083] In some embodiments, as Figure 5 As shown, a reinforcement plate 131 is provided within each of the ends of the upper and lower air deflectors 130 and 140, distal from their respective rotational axes. The reinforcement plates 131 effectively prevent the air deflectors from bending, deforming, or sagging under stress or prolonged use when the air deflectors are closed and abut against the limit posts 120, or when the upper and lower air deflectors are superimposed on each other. This ensures the sealing reliability of the air deflector assembly when the horizontal air outlet 112 is closed. This design not only improves the structural stability of the air deflectors but also enhances the sealing effectiveness of the horizontal air outlet in different air supply modes, preventing air leakage and condensation.

[0084] In some embodiments, the air deflector is a multi-layer assembly structure, and the outer layer is composed of a flexible material layer and a plastic shell. When the upper air deflector 130 and the lower air deflector 140 form the overlapping area 160, the contact surface of at least one air deflector in the overlapping area 160 is the flexible material layer. The flexible material layer can be made of rubber, silicone or other elastic materials, which can produce a slight compression deformation when the air deflectors are overlapped, thereby filling the gap between the air deflectors and improving the sealing effect. This design ensures good sealing when the air deflectors in the overlapping area 160 are subjected to contact pressure, and can also buffer the impact, reduce friction and noise between the air deflectors, prolong the service life of the air deflectors, and effectively prevent scratches or damage caused by direct contact of rigid materials.

[0085] In a second aspect, the embodiments of the present application provide a ducted air conditioner, the main structure of which includes a fan system 200, a heat exchange system 300 and a distribution box 100. The heat exchange system 300 is connected with the fan system 200. The distribution box 100 is arranged at the air outlet side of the heat exchange system 300. A control system can also be arranged in the ducted air conditioner.

[0086] It should be noted that the fan system 200 generally includes a volute, a motor, a fan blade, etc. The fan system 200 is not covered by a shell to increase the area of the return air passage and improve the heat exchange efficiency. The control system is generally an electric control box or an electric control cabinet, which is connected in communication with the fan system 200, the heat exchange system 300 and the distribution box 100. The opening side of the distribution box 100 (i.e. the side opposite to the horizontal air outlet 112) is connected with the heat exchange system 300.

[0087] The heat exchange system 300 includes a shell 310, a V-shaped heat exchanger and a water pan 320. The shell 310 forms an air duct inside, and the air duct forms an air inlet and an air outlet on both sides. A fan is configured to introduce airflow from the air inlet into the air duct. The outlet end of the fan is in communication with the air inlet of the air duct. The fan is preferably a cross-flow fan or a centrifugal fan, which has stable output air speed and moderate air volume. The V-shaped heat exchanger includes a first heat exchanger 330 and a second heat exchanger 340 arranged in a vertical direction. The water pan 320 is located below the V-shaped heat exchanger. The shape of the water pan 320 can be rectangular, trapezoidal or arc-shaped according to the profile of the heat exchanger. The lower part of the water pan 320 is provided with a drain port or a drain pipe interface to uniformly guide the collected condensed water to the drainage system. The water pan 320 is located in the lower area of the V-shaped heat exchanger to directly receive the condensed water dripping from the V-shaped heat exchanger.

[0088] In the refrigeration or dehumidification mode of the air conditioner, the V-shaped heat exchanger surface is prone to produce condensate water due to temperature reduction. Part of the condensate water will naturally drip along the pipe wall to the lower part, and this part of the condensate water can be directly received and discharged by the water pan 320. Another part of the condensate water is passively taken away from the heat exchanger surface under the action of airflow impact, and the condensate water is easily carried to the air outlet area of the V-shaped heat exchanger. After a long time, it will be collected in the unit. In order to collect and discharge such condensate water, in some embodiments, when the lower air deflector 140 is rotated to close the vertical air outlet 111, the free end of the lower air deflector 140 overlaps the water pan 320. Along the direction gradually close to the water pan 320, the height of the lower air deflector 140 gradually decreases, forming an effective condensate water flow guide surface. The condensate water condensed and dripped from the V-shaped heat exchanger or splashed by strong airflow to the air outlet side falls on the lower air deflector 140 under the action of gravity, flows along the lower air deflector 140, and is finally guided into the water pan 320.

[0089] The application further provides a control method of the ducted air conditioner, which is applied to the ducted air conditioner provided by the application. The control method comprises: controlling the position of the air deflector assembly according to the operation mode of the ducted air conditioner, so as to realize the opening and closing or opening degree adjustment of the horizontal air outlet 112 and the vertical air outlet 111.

[0090] Optionally, the control method comprises: controlling the rotation of the upper air deflector 130 between the first position A and the second position B and controlling the rotation of the lower air deflector 140 between the third position C, the fourth position D and the fifth position E according to the operation mode of the ducted air conditioner and the personnel distance between the ducted air conditioner and the personnel in the space processed by the ducted air conditioner; wherein the operation mode of the ducted air conditioner comprises a personnel-avoiding mode and a personnel-blowing mode.

[0091] Optionally, the upper air deflector 130 and the lower air deflector 140 are both configured as flat plate structures; the upper air deflector 130 and the lower air deflector 140 are independently rotated relative to each other.

[0092] Optionally, when the upper air deflector 130 and the lower air deflector 140 both maintain the state of closing the horizontal air outlet 112, the upper air deflector 130 and the lower air deflector 140 jointly constitute the air outlet area of the horizontal air outlet 112.

[0093] Optionally, 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 completely open the upper region of the horizontal air outlet 112.

[0094] In the present disclosure, considering that flexible adjustment of long-distance air supply and short-distance air supply can be realized according to actual conditions, in the control method provided by the present disclosure, according to the operation mode of the duct type air conditioner and the personnel distance between the duct type air conditioner and the personnel in the space processed by the duct type air conditioner, the upper air deflector 130 is controlled to rotate between the first position A and the second position B, and the lower air deflector 140 is controlled to rotate between the third position C, the fourth position D and the fifth position E; wherein the operation mode of the duct type air conditioner includes a person-avoiding mode and a person-blowing mode; in this way, according to different scene requirements, the opening and closing positions of the upper air deflector 130 and the lower air deflector 140 can be controlled respectively, so as to realize the size adjustment of the opening of the horizontal air outlet 112 and the opening of the vertical air outlet 111, by controlling the rotating opening and closing positions of the upper air deflector 130 and the lower air deflector 140, the airflow direction and airflow speed can be changed, different air outlet modes can be realized, various use scene requirements of users can be adapted, in addition, the air supply range can be increased, the refrigeration and heating effects can be improved, and the user experience can be improved.

[0095] Specifically, the duct type air conditioner is constructed with flexible and variable air outlet channels by setting the horizontal air outlet 112 (front side) and the vertical air outlet 111 (lower side), and cooperating with the rotatable upper air deflector 130 and the lower air deflector 140. The upper air deflector 130 controls the opening and closing of the upper region of the horizontal air outlet 112, and the lower air deflector 140 can switch between the lower part of the horizontal air outlet 112 and the vertical air outlet 111, which enriches the selection of air outlet paths and provides a hardware basis for precise air supply. Further, based on the dual-dimension regulation of the air deflector according to the "operation mode (person-avoiding / person-blowing) + personnel distance", an intelligent air supply logic is constructed: in the person-blowing mode, the opening degree of the upper air deflector 130 (A / B switching) and the position of the lower air deflector 140 (C / D / E adaptation) are dynamically adjusted according to the personnel distance, so that the cold / hot air can accurately reach the personnel activity area, and the comfortable feeling is strengthened; in the person-avoiding mode, the upper air deflector 130 blocks the upper part, and the lower air deflector 140 is adaptively positioned (such as C blocks the lower part of the horizontal air outlet 112 or E blocks the vertical air outlet 111), so as to forcibly change the airflow direction and avoid direct blowing to the human body to cause discomfort. The linkage regulation of the double air deflectors enables the duct type air conditioner to adapt to various space scenes (such as short-distance rest and long-distance whole-house air supply), significantly improves the air supply accuracy and user experience, and realizes the technical breakthrough of "on-demand air supply and intelligent disturbance avoidance".

[0096] Consider one of the application scenarios:

[0097] According to the operation mode of the duct type air conditioner and the personnel distance between the duct type air conditioner and the personnel in the space processed by the duct type air conditioner, the upper air deflector 130 is controlled to rotate between the first position A and the second position B, and the lower air deflector 140 is controlled to rotate between the third position C, the fourth position D and the fifth position E, including:

[0098] In the case that the ducted air conditioner is in the human-avoiding mode and the distance between the personnel and the ducted air conditioner is greater than or equal to the set distance, the upper air deflector 130 is controlled to rotate to the second position B, and the lower air deflector 140 is controlled to rotate to the fourth position D.

[0099] In this way, under the driving of the control logic, the upper air deflector 130 opens the upper part of the horizontal air outlet 112, and the lower air deflector 140 is positioned at the fourth position D (a transition state connecting the lower part of the horizontal air outlet 112 and the vertical air outlet 111), so that the airflow sent by the fan can form a more reasonable flow path. The airflow can be guided to a wider area through the lower air deflector 140 from the upper part of the horizontal air outlet 112, promoting air circulation in the space and accelerating the temperature control speed. Especially when the temperature needs to be quickly and evenly adjusted in a large space, this combination of air deflector positions can make cold and hot air more efficiently cover the space, shorten the time for temperature adjustment, and enhance the energy efficiency of air conditioner operation.

[0100] Consider the second application scenario:

[0101] According to the operation mode of the ducted air conditioner and the distance between the personnel and the ducted air conditioner, the upper air deflector 130 is controlled to rotate between the first position A and the second position B, and the lower air deflector 140 is controlled to rotate between the third position C, the fourth position D, and the fifth position E, including:

[0102] In the case that the ducted air conditioner is in the human-avoiding mode and the distance between the personnel and the ducted air conditioner is less than the set distance, the upper air deflector 130 is controlled to rotate to the second position B, and the lower air deflector 140 is controlled to rotate to the fourth position D.

[0103] In this way, under the driving of the control logic, the upper air deflector 130 opens the upper part of the horizontal air outlet 112, and the lower air deflector 140 is positioned at the fourth position D (a transition state connecting the lower part of the horizontal air outlet 112 and the vertical air outlet 111), so that the airflow sent by the fan can form a more reasonable flow path. The airflow can be guided to a wider area through the lower air deflector 140 from the upper part of the horizontal air outlet 112, promoting air circulation in the space and accelerating the temperature control speed. Especially when the temperature needs to be quickly and evenly adjusted in a large space, this combination of air deflector positions can make cold and hot air more efficiently cover the space, shorten the time for temperature adjustment, and enhance the energy efficiency of air conditioner operation.

[0104] Consideration of application scenario three:

[0105] According to the operation mode of the ducted fan and the personnel distance between the ducted fan and the personnel in the space handled by the ducted fan, the rotation of the upper air deflector 130 between the first position A and the second position B is controlled, and the rotation of the lower air deflector 140 between the third position C, the fourth position D and the fifth position E is controlled, including:

[0106] In the case that the ducted fan is in the blowing mode and the personnel distance is greater than or equal to the set distance, the upper air deflector 130 is controlled to rotate to the second position B, and the lower air deflector 140 is controlled to rotate to the fifth position E.

[0107] In this way, under this control logic, the upper air deflector 130 opens the upper area to ensure the air flow, and the lower air deflector 140 blocks the vertical air outlet 111 to reduce the airflow diversion loss, so that the airflow output by the fan is concentrated from the upper part of the horizontal air outlet 112, which significantly improves the air supply pressure and range. Combined with the flow guiding effect of the upper air deflector 130 at the second position B, the airflow can form a more optimal diffusion angle and air supply track, which can quickly cover the long-distance space range and speed up the space temperature equalization speed. Compared with the air supply mode of multiple air outlets diversion, this concentrated air supply mode has higher energy efficiency in long-distance scenarios, reduces unnecessary energy loss, and improves the economy and practicality of air conditioner operation. The "blowing mode + long distance" can be accurately controlled, which further expands the intelligent adaptation boundary of the ducted fan. When the user is in a long-distance activity (such as relaxing 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 deflection angle, and the air conditioner can automatically realize directional air supply through the air deflector position combination. This design strengthens the response capability of the product to different personnel distances and different use scenarios, upgrades the air conditioner from "passive temperature regulation" to "active demand adaptation" intelligent equipment, improves the user experience, highlights the technical advantages of the product in air supply precision and scene compatibility, and enhances the market competitiveness.

[0108] Consideration of application scenario four:

[0109] According to the operation mode of the ducted fan and the personnel distance between the ducted fan and the personnel in the space handled by the ducted fan, the rotation of the upper air deflector 130 between the first position A and the second position B is controlled, and the rotation of the lower air deflector 140 between the third position C, the fourth position D and the fifth position E is controlled, including:

[0110] In the case that the ducted fan is in the blowing mode and the personnel distance is less than the set distance, the upper air deflector 130 is controlled to rotate to the first position A, and the lower air deflector 140 is controlled to rotate to the third position C.

[0111] In this way, under the control logic, the upper air deflector 130 blocks the upper part of the horizontal air outlet 112, the lower air deflector 140 blocks the lower part of the horizontal air outlet 112, and the airflow is forced to be guided out of the vertical air outlet 111, changing the airflow direction of the traditional close-range air supply. The vertical air outlet 111 is located on the lower side of the cabinet 110, and the air supply can diffuse along the lower part of the space, reducing the direct blowing on the head and face of the human body, and reducing the discomfort caused by close-range strong wind direct blowing (such as dry skin and joint cooling). At the same time, the concentrated air supply from the vertical air outlet 111 can make the airflow more evenly cover the middle and lower parts of the human body activity area, improve the body comfort, and enhance the safety of close-range air conditioner use. This method can be used for special regulation in the "blowing mode + close-range" sub-scene, further improving the scene adaptation system of the ducted air conditioner. When the user is in a close-range activity state (such as lying in bed before sleeping or sitting for a long time), the air conditioner can automatically identify the distance of the personnel and adjust the position of the air deflector, without the need for manual intervention to provide an adaptive air supply mode. This design improves the response speed and regulation accuracy of the product in different distance scenes, enables the air conditioner to dynamically optimize the air supply strategy according to the position of the personnel, enhances the intelligent property and user experience of the product, and highlights the technical advantages and market competitiveness in the close-range blowing scene.

[0112] Considering that the ducted air conditioner can have a new control scheme of the fan speed in the fan system 200, in the control method provided by the embodiment of the disclosure, the control method comprises:

[0113] Controlling the speed of the fan in the fan system 200 according to the operation mode of the ducted air conditioner, the ambient temperature, the personnel temperature, and the personnel distance.

[0114] In this way, the speed of the fan in the fan system 200 is regulated in combination with the operation mode (blowing mode / avoiding mode), the ambient temperature, the personnel temperature, and the personnel distance, so that precise air supply regulation of multi-dimensional parameter linkage can be realized. In the blowing mode, if the difference between the ambient temperature and the personnel temperature is large and the personnel distance is close, the speed can be increased to enhance the air supply intensity and quickly reduce the temperature difference; in the avoiding mode or when the personnel distance is far, the speed is dynamically reduced in combination with the ambient temperature and the personnel temperature, so that the space temperature control requirement can be met, the airflow disturbance and energy consumption can be reduced, the fan in the fan system 200 can operate more adaptively to the actual scene requirement, and the overall regulation efficiency and user experience are improved.

[0115] Considering that the ducted air conditioner can have one of the specific control schemes of the fan speed in the fan system 200, in the control method provided by the embodiment of the disclosure, the speed of the fan in the fan system 200 is controlled according to the operation mode of the ducted air conditioner, the ambient temperature, the personnel temperature, and the personnel distance, comprising:

[0116] When the operation mode of the ducted air conditioner, the ambient temperature, the personnel temperature, and the personnel distance satisfy any one of the sub-conditions in the first set of conditions, the speed of the fan in the fan system 200 is increased;

[0117] wherein the first set condition comprises:

[0118] a first sub-condition, the ducted-type air conditioner is in the people-avoiding mode, the temperature difference between the personnel temperature and the ambient temperature is less than the set temperature, and the personnel distance is greater than or equal to the set distance;

[0119] a second sub-condition, the ducted-type air conditioner is in the people-avoiding mode, the temperature difference between the personnel temperature and the ambient temperature is less than the set temperature, and the personnel distance is less than the set distance;

[0120] a third sub-condition, the ducted-type air conditioner is in the people-blowing mode, the temperature difference between the personnel temperature and the ambient temperature is less than the set temperature, and the personnel distance is greater than or equal to the set distance;

[0121] a fourth sub-condition, the ducted-type air conditioner is in the people-blowing mode, the temperature difference between the personnel temperature and the ambient temperature is less than the set temperature, and the personnel distance is less than the set distance.

[0122] In this way, under any of the sub-conditions of the first set condition, the fan speed in the fan system 200 is controlled to increase, which can specifically address the temperature control needs of the core scenario of the temperature difference between the personnel temperature and the ambient temperature being less than the set temperature. Whether in the people-avoiding mode or the people-blowing mode, and whether the personnel distance is far or near, when the temperature difference is small, increasing the fan speed in the fan system 200 can enhance the efficiency of air intake and air outlet, speed up the air circulation and regulation speed of the air conditioner in the space, and promote the personnel temperature and the ambient temperature to approach the target temperature difference, thereby avoiding the problem of ineffective temperature control due to insufficient temperature difference, and providing power support for rapid temperature control in different modes and distance scenarios.

[0123] Further, the control logic links the operation mode, the temperature difference, the personnel distance, and the fan speed in the fan system 200, to achieve fine dynamic adjustment. In the people-avoiding mode, increasing the speed can strengthen the air diffusion capacity to ensure efficient heat exchange in spaces at a far or near distance; in the people-blowing mode, increasing the speed can enhance the air supply intensity to make the air flow more accurately and quickly act on the personnel area. This multi-scenario adaptive speed regulation strategy not only improves the temperature control response speed of the air conditioner when the temperature difference is small, but also ensures the air supply effect in different modes, further optimizing the intelligent adjustment performance and user experience of the product.

[0124] Considering that the ducted-type air conditioner can have one of the specific control schemes of the fan speed in the new fan system 200, in the control method provided by the embodiments of the present disclosure, the fan speed in the fan system 200 is controlled according to the operation mode of the ducted-type air conditioner, the ambient temperature, the personnel temperature, and the personnel distance, comprising:

[0125] under the condition that the operation mode of the ducted-type air conditioner, the ambient temperature, the personnel temperature, and the personnel distance meet any of the sub-conditions of the second set condition, the fan speed in the fan system 200 is controlled to decrease;

[0126] The second set condition comprises:

[0127] The fifth sub-condition is that the ducted-type air conditioner is in the people-avoiding mode, 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.

[0128] The sixth sub-condition is that the ducted-type air conditioner is in the people-avoiding mode, 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 less than the set distance.

[0129] The seventh sub-condition is that the ducted-type air conditioner is in the people-blowing mode, 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.

[0130] The eighth sub-condition is that the ducted-type air conditioner is in the people-blowing mode, 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 less than the set distance.

[0131] In this way, under any sub-condition of the second set condition, the fan speed in the fan system 200 is controlled to be reduced, which can adapt to the scene requirement of the temperature difference between the personnel temperature and the ambient temperature being greater than or equal to the set temperature. Whether in the people-avoiding mode or the people-blowing mode, and whether the personnel distance is far or near, when the temperature difference reaches the target range, reducing the fan speed in the fan system 200 can reduce unnecessary energy consumption and air flow disturbance, avoid the influence of strong air flow diffusion on the quietness of the space in the people-avoiding mode, and prevent over-strong air supply from causing human discomfort in the people-blowing mode. Through the multi-parameter linkage of the fan speed control, the balance between stable temperature control effect and energy saving and comfort is achieved, and the product operation energy efficiency and user experience are further optimized.

[0132] Considering the specific rotation scheme of the upper air guide plate 130 and the lower air guide plate 140, in the ducted-type air conditioner provided in the embodiments of the present disclosure, the upper air guide plate 130 is rotationally connected to the box body 110 through a first rotation shaft, and the lower air guide plate 140 is rotationally connected to the box body 110 through a second rotation shaft. This provides a structural basis for the precise rotation and stable positioning of the air guide plate. The first rotation shaft supports the upper air guide plate 130 to flexibly switch between the first position A and the second position B, thereby reliably opening and closing the upper region of the horizontal air outlet 112; and the second rotation shaft ensures the smooth rotation of the lower air guide plate 140 between the third, fourth, and fifth positions, thereby accurately completing the switching between the control of the lower region of the horizontal air outlet 112 and the vertical air outlet 111. This rotation shaft connection structure ensures the stability and controllability of the rotation of the air guide plate, provides reliable mechanical support for the linkage control of the air guide plate based on the operation mode and the personnel distance, and further improves the accuracy and scene adaptability of the air outlet control of the ducted-type air conditioner, thereby strengthening the feasibility and effectiveness of the overall air supply scheme.

[0133] In consideration of the specific driving scheme of the first rotating shaft, the air duct machine provided by the embodiment of the present disclosure includes a first driving motor, which is drivingly connected with the first rotating shaft, and is used to drive the first rotating shaft to rotate to different preset angles in different situations, so that the upper air deflector 130 is stopped at the first position A or the second position B.

[0134] In this way, the design that the first driving motor is drivingly connected with the first rotating shaft provides power support for the accurate positioning and automatic regulation of the upper air deflector 130. The first driving motor can drive the first rotating shaft to rotate to different preset angles according to the control instruction, so that the upper air deflector 130 can be reliably stopped at the first position A (blocking the upper region of the horizontal air outlet 112) or the second position B (opening the upper region of the horizontal air outlet 112), replacing the limitations of traditional manual adjustment or non-driven positioning. This driving scheme ensures the quick response and accurate switching of the upper air deflector 130 in different operation modes and personnel distance scenarios, strengthens the synchronization and reliability of the linkage regulation of the upper air deflector 130 and the lower air deflector 140, provides core power support for the intelligent and automatic adjustment of the air deflector in the overall air supply scheme, and further improves the accuracy and efficiency of the air duct machine air outlet regulation.

[0135] In consideration of the specific driving scheme of the second rotating shaft, the air duct machine provided by the embodiment of the present disclosure includes a second driving motor, which is drivingly connected with the second rotating shaft, and is used to drive the second rotating shaft to rotate to different preset angles in different situations, so that the lower air deflector 140 is stopped at the third position C, the fourth position D or the fifth position E.

[0136] In this way, the design that the second driving motor is drivingly connected with the second rotating shaft provides reliable power support for the multi-position accurate positioning and automatic regulation of the lower air deflector 140. The second driving motor can drive the second rotating shaft to rotate to different preset angles according to the control instruction, so that the lower air deflector 140 is stably stopped at the third position C (blocking the lower region of the horizontal air outlet 112), the fourth position D (transition position) or the fifth position E (blocking the vertical air outlet 111), breaking through the limitations of the traditional air deflector adjustment mode. This driving scheme ensures the flexible switching and accurate positioning of the lower air deflector 140 in different operation modes and personnel distance scenarios, enhances the coordination of the linkage regulation of the lower air deflector 140 and the upper air deflector 130, provides key driving support for the air deflector to dynamically adapt the air outlet path according to the scene in the overall air supply scheme, and further improves the flexibility, reliability and intelligent level of the air duct machine air outlet regulation.

[0137] In consideration of the scheme that the air duct machine is used to detect the environmental temperature, the personnel temperature and the personnel distance, the air duct machine provided by the embodiment of the present disclosure includes a temperature sensor and a human body sensor. The temperature sensor is used to monitor the environmental temperature in real time, and the human body sensor is used to monitor the distance of the personnel relative to the air duct machine and the personnel temperature in real time.

[0138] In this way, the temperature sensor monitors the ambient temperature in real time, and the human body sensor synchronously acquires the relative distance and temperature of the person, which provides accurate scene parameter input basis for the overall control scheme. The temperature sensor ensures the real-time and accuracy of the ambient temperature data, and the human body sensor realizes the synchronous monitoring of the distance (far / near) and temperature of the person, which together constitute the core data support for the switching of the operation mode, the position control of the deflector, and the adjustment of the fan speed in the fan system 200. This sensing and detection scheme enables the ducted air conditioner to dynamically perceive the space environment and the state of the person, and provides reliable parameters for the functions such as "avoiding people / blowing people mode adaptation", "deflector multi-position linkage", and "dynamic adjustment of fan speed in fan system 200", which ensures that the control strategies can accurately respond to the actual scene requirements, and enhances the scientificity and effectiveness of the intelligent air supply of the ducted air conditioner from the perception layer, and improves the closed-loop control ability of the overall scheme.

[0139] In summary, in order to better understand the scheme of the ducted air conditioner of the present disclosure, the following embodiments are used for auxiliary description:

[0140] The ducted air conditioner refers to Figure 8 The upper deflector 130 and the lower deflector 140 are both in the fully open state, and the air is blown out from the front side to realize long-distance air supply. The air supply distance can be adjusted by: ① adjusting the fan speed in the fan system 200 alone; ② adjusting the opening angle of the upper deflector 130 alone; and ③ adjusting the fan speed in the fan system 200 and the opening angle of the upper deflector 130 simultaneously.

[0141] The ducted air conditioner refers to Figure 9 The upper deflector 130 and the lower deflector 140 are both in the fully closed state, and the air is blown out from the lower side to realize downward air supply. The air supply distance can be adjusted by adjusting the fan speed in the fan system 200 alone.

[0142] The ducted air conditioner refers to Figure 10 The upper deflector 130 is fully open, and the lower deflector 140 is half open, and the air is blown out from the front side and the lower side at the same time to realize medium-distance surrounding air supply, realize rapid temperature adjustment, and improve comfort. Similarly, the air outlet strength can be adjusted by: ① adjusting the fan speed in the fan system 200 alone; ② adjusting the opening angles of the upper deflector 130 and the lower deflector 140 alone; and ③ adjusting the fan speed in the fan system 200 and the opening angle of the lower deflector 140 simultaneously.

[0143] The ducted air conditioner refers to Figure 11 The upper deflector 130 is fully closed, and the lower deflector 140 is half open.

[0144] Based on the independent movement control of the upper and lower air deflectors 130 and 140, the unit is matched with temperature and human body detection devices such as infrared sensors (the sensors can be arranged on the front side of the unit or independently externally arranged on the ceiling), and the opening degree of the upper and lower air deflectors 140 and the fan speed in the fan system 200 are adjusted according to the position of the person and the temperature difference between the person and the environment, so as to realize the use scene requirements of the wind blowing the person or the wind following the person.
