[0054] 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.

[0055] 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.

[0056] 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.

[0057] Ductless air conditioners, also known as ducted units, deliver air into the room via ductwork. Currently, ductless units are a popular choice for central air conditioning units due to their aesthetic appeal and space-saving design, making them a favorite among younger consumers. However, conventional ductless units typically have only one air outlet, which is unsuitable for some open-plan kitchen designs. Often, the air conditioner is installed in the area between the dining room and living room. To simultaneously meet the cooling needs of both spaces, users usually need to install two units: one with its outlet facing the dining room and the other facing the living room, with a return air vent at the bottom of the ceiling. This selection and installation method results in high overall unit costs and an unsightly appearance. Furthermore, when the horizontal air outlet uses two or more sealing plates for switching between closing and closing, the long and insufficiently rigid guide plates may lead to poor sealing, causing condensation and air leakage.

[0058] Firstly, such as Figure 1-4As shown, in view of the above-mentioned technical problems, this application provides an air guide structure 1000, including: an air guide shell 10, which has a lower air outlet 1201 on its bottom surface and a horizontal air outlet 1401 on its side; a limiting component 20, which has a horizontal limiting post 210, which is disposed inside the horizontal air outlet 1401; and an air guide plate assembly 30, which is rotatably disposed on both sides of the horizontal air outlet 1401 to close or open the horizontal air outlet 1401; wherein, the horizontal limiting post 210 is provided with a sealing male buckle 2101, and the end of the air guide plate assembly 30 away from the rotation axis is provided with a sealing female buckle 3101, so that when the air guide plate assembly 30 closes the horizontal air outlet 1401, the sealing female buckle 3101 and the sealing male buckle 2101 are engaged.

[0059] It should be noted that by setting a lower air outlet 1201 on the bottom surface of the air guide housing 10, setting a horizontal air outlet 1401 on the side surface of the air guide housing 10, and setting air guide plate assemblies 30 on both sides of the horizontal air outlet 1401, the horizontal air outlet 1401 can be closed or opened by the air guide plate assemblies 30 to achieve air supply in two directions. This allows the ducted air conditioner arranged in the area between the dining room and the living room to supply air to the dining room and the living room separately or simultaneously. At the same time, by setting a sealing male buckle 2101 on the horizontal limiting column 210 and a sealing female buckle 3101 on the end of the air guide plate assembly 30 away from the rotation axis, the sealing female buckle 3101 and the sealing male buckle 2101 can be engaged when the air guide plate assembly 30 closes the horizontal air outlet 1401, ensuring a sealing effect.

[0060] In some embodiments, the limiting component 20 includes: a horizontal limiting post 210, which is horizontally disposed in the horizontal air outlet 1401 and has two sealing male buckles 2101 arranged in a centrally symmetrical manner and extending outward; and a limiting post drive motor 220, which is connected to the horizontal limiting post 210 and is used to drive the horizontal limiting post 210 to rotate.

[0061] It should be noted that by placing the horizontal limiting post 210 horizontally (i.e., laterally) within the horizontal air outlet 1401, the larger horizontal air outlet 1401 can be divided, avoiding the problem that the larger (or higher) horizontal air outlet 1401 would require a larger air guide plate assembly 30, thus avoiding the need for a larger drive motor to drive the air guide plate assembly 30 and the problem that the air guide plate assembly 30 is too large and prone to deformation. Among them, the sealing male buckle 2101 is usually set in a continuous length, that is, the same length as the main body of the horizontal limiting post 210 (excluding the rotating shaft part, which is used to connect to the limiting post drive motor 220). The sealing female buckle 3101 is also arranged in a continuous length on the air guide plate assembly 30 so that it can cooperate with the sealing male buckle 2101 to seal. The sealing male buckle 2101 can be a protrusion extending outward from the horizontal limiting post 210, and the sealing female buckle 3101 can be an annular groove.

[0062] In some embodiments, the horizontal limiting post 210 is a hollow structure, including an internal profile post and a limiting sealing layer outside the profile post.

[0063] It should be noted that the profile column can be made of aluminum profile. By setting the horizontal limiting column 210 as a hollow structure, the strength of the horizontal limiting column 210 can be enhanced and its weight reduced, so as to avoid deformation of the horizontal limiting column 210 and thus the problem of air leakage. The limiting sealing layer is made of flexible material, such as rubber or polymer elastic material. By setting the limiting sealing layer on the outside of the profile column, it can buffer when the horizontal limiting column 210 comes into contact with the air guide plate assembly 30, so as to avoid damage to the horizontal limiting column 210 and the air guide plate assembly 30.

[0064] In some embodiments, the air guide plate assembly 30 includes: a first switching air guide plate 310, rotatably disposed below the horizontal air outlet 1401, with a sealing nut 3101 on the inner side of the end away from the rotation axis; a second switching air guide plate 320, rotatably disposed above the horizontal air outlet 1401, with a sealing nut 3101 on the outer side of the end away from the rotation axis; and two switching motors 330, respectively connected to the first switching air guide plate 310 and the second switching air guide plate 320.

[0065] It should be noted that the two switching motors 330 are typically located inside the air guide housing 10, and the second switching air guide plate 320 is typically located inside the air guide housing 10 and rotates to open the horizontal air outlet 1401 to avoid the problems of occupying external space and poor aesthetics when opening to the outside of the air guide housing 10; the first switching air guide plate 310 is connected to the air guide housing 10 below the horizontal air outlet 1401, and the width of the upper and lower air outlets 1201 of the air guide housing 10 can be less than the height of the horizontal air outlet 1401 after being divided by the horizontal limiting post 210, so that the first switching air guide plate 310 can be opened to the outside of the air guide housing 10. When the air guide plate 310 rotates inside the air guide housing 10 to open the horizontal air outlet 1401, it can cover the lower air outlet 1201, thereby achieving horizontal air supply or vertical air supply downwards independently. When the first switching air guide plate 310 rotates to the middle position (i.e., not covering the lower air outlet 1201, but at an angle of 30°, 45°, etc.), it can achieve simultaneous horizontal and vertical air supply. The air supply volume in the horizontal and vertical directions can be distributed by adjusting the angle of the first switching air guide plate 310 to meet the user's needs. The switching motor 330 can be a stepper motor, servo motor, etc.

[0066] It should be noted that, as Figure 6-7As shown, by respectively setting the two sealing female buckles 3101 on the inner side of the first switching air guide plate 310 and the outer side of the second switching air guide plate 320, when the horizontal air outlet 1401 is closed, the two sealing female buckles 3101 can cooperate with the sealing male buckles 2101 centrally symmetrically arranged on the horizontal limiting post 210; and when the horizontal air outlet 1401 is opened, the engagement of the sealing male buckles 2101 and the sealing female buckles 3101 can be released by rotating the horizontal limiting post 210 (such as clockwise rotation). Then, the first switching air guide plate 310 and the second switching air guide plate 320 are opened by two switching motors 330. The first switching air guide plate 310 and the second switching air guide plate 320 near the horizontal limiting post 210 can be provided with a preset gap between them to avoid collision between the first switching air guide plate 310 and the second switching air guide plate 320 and the horizontal limiting post 210. The preset gap can be 3-5mm, and flexible material can be filled in the preset gap to avoid air leakage.

[0067] In some embodiments, the first switching air guide plate and / or the second switching air guide plate include: an air guide housing; a rotating shaft disposed on one side of the air guide housing; and an air guide flexible layer disposed outside the air guide housing.

[0068] It should be noted that the first switching air guide plate and / or the second switching air guide plate are connected to the switching motor 330 via a rotating shaft. The air guide housing can be a plastic housing to reduce its weight. The air guide housing can be a hollow structure with several supporting structures inside to enhance its strength and reduce its weight. The air guide flexible layer can be made of flexible materials, such as rubber, plastic, or high-molecular elastic materials. By setting the air guide flexible layer, the buffering effect when the first switching air guide plate, the second switching air guide plate, and the horizontal limiting post 210 or other components come into contact can be increased, and abnormal noise can be avoided.

[0069] In some embodiments, the switching motor 330 is a stepper motor.

[0070] It should be noted that a stepper motor converts electrical pulse signals into corresponding angular or linear displacement. For each input pulse signal, the rotor rotates by one angle or moves forward one step. The output angular or linear displacement is proportional to the number of input pulses, and the rotational speed is proportional to the pulse frequency. Therefore, using a stepper motor facilitates the control of the rotation angles of the first and second switching air guides, thereby enabling accurate control of the airflow direction and volume.

[0071] In some embodiments, the air guide housing 10 includes: an air guide front side plate with a horizontal air outlet 1401 thereon; an air guide bottom plate 120 located below the air guide front side plate with a lower air outlet 1201 thereon; an air guide top plate 110 located above the air guide front side plate; and an air guide right vertical plate 130 located between the air guide bottom plate 120 and the air guide top plate 110 and connected to the air guide front side plate.

[0072] It should be noted that in actual production and use, the air guide bottom plate 120 can be extended downwards and the air guide top plate 110 can be lowered to form a horizontal air outlet 1401, thus eliminating the need to set up the air guide front side plate. Whether to set up the air guide left vertical plate can be determined according to actual needs. If there are other components on the left side of the air guide housing 10 that can abut against it, the air guide left vertical plate can be removed and the left side of the air guide housing 10 can be directly abutted against the component. If there are no other components on the left side of the air guide housing 10 that can abut against it, the air guide left vertical plate can be set up. The material of the air guide housing 10 can be aluminum, plastic, etc.

[0073] In some embodiments, the sealing female buckle 3101 and the sealing male buckle 2101 are interference fit.

[0074] It should be noted that by making the sealing female buckle 3101 and the sealing male buckle 2101 an interference fit, the sealing effect between the air guide assembly and the horizontal limiting post 210 can be improved, thus avoiding air leakage problems.

[0075] In summary, the air guide structure 1000 and duct-type air conditioner provided in this application embodiment, by setting a lower air outlet 1201 on the bottom surface of the air guide housing 10, setting a horizontal air outlet 1401 on the side surface of the air guide housing 10, and setting air guide plate assemblies 30 on both sides of the horizontal air outlet 1401, can achieve air delivery in two directions by closing or opening the horizontal air outlet 1401 through the air guide plate assembly 30; by setting a sealing male buckle 2101 on the horizontal limiting post 210 and setting a sealing female buckle 3101 at the end of the air guide plate assembly 30 away from the rotation axis, the sealing female buckle 3101 and the sealing male buckle 2101 can be engaged when the air guide plate assembly 30 closes the horizontal air outlet 1401, ensuring the sealing effect.

[0076] Secondly, such as Figure 5-7 As shown, this application provides a ducted air conditioner, including: a fan system 2000; a heat exchange system 3000 connected to the fan system 2000; an air guide structure 1000, as in any embodiment of the first aspect, attached to the air outlet side of the heat exchange system 3000; and a control system 4000 for controlling the fan system 2000, the heat exchange system 3000, and the air guide structure 1000.

[0077] It should be noted that the fan system 2000 typically includes a volute, motor, and fan blades. The fan system 2000 has no external casing to increase the return air channel area and improve heat exchange efficiency. The control system 4000 is typically an electrical control box or control enclosure, which is connected to the fan system 2000, the heat exchange system 3000, and the air guide structure 1000. The open side of the air guide structure 1000 (i.e., the opposite side of the front air guide plate) is connected to the heat exchange system 3000, and the left side of the air guide structure 1000 abuts against the control system 4000 to avoid the need for a left vertical air guide plate, thereby saving materials.

[0078] In some embodiments, the lower outer part of the heat exchange system 3000 has an overlapping boss 3001, the height of which is greater than the height of the lower air outlet 1201. The oblique distance from the overlapping boss 3001 to the rotation axis of the first switching air guide plate 310 is less than or equal to the height of the first switching air guide plate 310, so that the first switching air guide plate 310 can overlap the overlapping boss 3001, thereby shielding the lower air outlet 1201.

[0079] It should be noted that, considering the large height of the horizontal air outlet 1401, even with the horizontal limiting post 210 dividing the horizontal air outlet 1401, the height of the horizontal air outlet 1401 below the horizontal limiting post 210 is still large (greater than the distance between the horizontal air outlet 1401 and the heat exchange system 3000). In this case, the first switching guide plate 310 cannot rotate to cover the lower air outlet 1201. By providing an overlapping protrusion 3001 on the lower outer side of the heat exchange system 3000, the first switching guide plate 310 can be rotated to the overlapping protrusion 3001 when the horizontal air outlet 1401 is opened. This allows the horizontal air outlet 1401 to be opened while simultaneously covering the lower air outlet 1201, reducing the width of the air guide structure 1000. Figure 6 , 7 As shown, when the first switching air guide plate 310 and the second switching air guide plate 320 are closed, the first switching air guide plate 310 is located at point d and the second switching air guide plate 320 is located at point b; when the first switching air guide plate 310 and the second switching air guide plate 320 are open, the first switching air guide plate 310 is located at point c and the second switching air guide plate 320 is located at point a.
