Technical Field

[0001] This application relates to the field of air conditioners, and more particularly to an air guide mechanism and an air conditioner. Background Technology

[0002] As an important type of air conditioning equipment, ducted air conditioners are widely used in various scenarios such as residences, offices, and commercial complexes due to their advantages such as compact structure, concealed installation, and space saving. Existing traditional ducted air conditioners typically use cross-flow fans as the core air supply component, relying on mature airflow circulation design to achieve indoor temperature regulation. They are characterized by moderate air supply distance, low operating noise, and controllable manufacturing costs, and can meet basic cooling and heating needs.

[0003] However, the existing traditional ducted air conditioners have a single air outlet method, which limits the choice of installation location and cannot adapt to the characteristics of the difference in the density of hot and cold air. They are difficult to evenly cover the indoor space, resulting in extremely poor comfort and failing to meet users' needs for precise air outlet and high-quality adjustment. Summary of the Invention

[0004] This application provides an air guiding mechanism and an air conditioner to solve the problems of traditional ducted air conditioners having a single air outlet method, which leads to limited installation location selection and an inability to adapt to the characteristics of differences in the density of hot and cold air.

[0005] In a first aspect, this application provides an air guiding mechanism for use in an air conditioner, the air conditioner including a duct housing having an airflow channel within it, and the air guiding mechanism comprising: The mounting component is used to connect the air duct housing. A main air duct is opened inside the mounting component and is used to connect the airflow channel. A guide component is provided inside the main air duct. The guide component divides the end of the main air duct away from the airflow channel into a first air duct and a second air duct arranged at an angle. Both the first air duct and the second air duct are connected to the main air duct. The first air guide plate is rotatably disposed in the first air duct to block or expose the first air duct. The second air guide plate is rotatably disposed in the second air duct to either block or expose the second air duct.

[0006] Optionally, the guide member has a first guide surface and a second guide surface arranged at an angle at one end near the main air duct, the first guide surface being located in the first air duct and the second guide surface being located in the second air duct.

[0007] Optionally, the air guiding mechanism further includes a sweeping assembly, which is disposed in the main air duct. The sweeping assembly includes a sweeping component and a connecting component, which is connected to the mounting component. The sweeping component is rotatably disposed on the connecting component.

[0008] Optionally, the air-sweeping component includes a first air-sweeping section and a second air-sweeping section arranged at an angle, with at most a portion of the first air-sweeping section located in the first air duct and at most a portion of the second air-sweeping section located in the second air duct.

[0009] Optionally, the angle between the first swept section and the second swept section is not less than the angle between the first guide surface and the second guide surface.

[0010] Optionally, the first air guide plate has a first air guide portion at the end away from the main air duct, and the side wall of the first air guide portion can abut against the inner wall of the first air duct; the second air guide plate has a second air guide portion at the end away from the main air duct, and the side wall of the second air guide portion can abut against the inner wall of the second air duct.

[0011] Optionally, the first air guide plate has a first connecting portion and a first auxiliary air guide portion at one end near the main air duct, and the first connecting portion connects the first auxiliary air guide portion and the first air guide portion; the second air guide plate has a second connecting portion and a second auxiliary air guide portion at one end near the main air duct, and the second connecting portion connects the second auxiliary air guide portion and the second air guide portion.

[0012] Optionally, both the first and second air ducts are equipped with mesh covers.

[0013] Secondly, this application provides an air conditioner, including a duct housing and an air guiding mechanism provided in the first aspect of this application, wherein the duct housing is provided with an airflow channel, and the airflow channel is connected to the main duct.

[0014] Optionally, the air conditioner includes: The housing has a mounting cavity inside. The housing has a first air outlet, a second air outlet, and an air inlet communicating with the mounting cavity. The first air outlet is located on the side wall of the housing, the second air outlet is located on the bottom wall of the housing, and the air inlet is located on either the side wall or the bottom wall of the housing.

[0016] The technical solutions provided in this application have the following advantages compared with the prior art: The air guiding mechanism provided in this application divides the main air duct into a first air duct and a second air duct at an angle by setting air guide components. Combined with independently rotating first and second air guide plates, it can achieve multi-mode airflow control. For example, in cooling mode, rotating the second air guide plate blocks the second air duct while exposing the first air guide plate, allowing airflow to exit laterally through the first air duct. Utilizing the high density of cold air, it achieves uniform airflow from top to bottom. In heating mode, rotating the first air guide plate blocks the first air duct while exposing the second air guide plate, allowing airflow to exit downwards through the second air duct. This allows hot air to spread from bottom to top, covering the indoor space and effectively solving the problem that traditional single airflow methods cannot adapt to the density differences between cold and hot air. Simultaneously, it supports partial or full opening of both the first and second air guide plates, achieving multi-angle, wide-area airflow to meet the needs of different users. The independent adjustment function of the first and second air guide plates allows for precise control of the airflow direction based on the indoor space layout and user activity area, avoiding direct airflow discomfort and improving air conditioning efficiency.

[0025] To address the technical problems of traditional ducted air conditioners having a single air outlet mode, which limits the choice of installation location and cannot adapt to the differences in the density of hot and cold air, this application provides an air guiding mechanism device. The main air duct 1a is divided into a first air duct 1b and a second air duct 1c at an angle by a guide member 2. With the independent rotation of the first air guide plate 3 and the second air guide plate 4, multi-mode air outlet control can be achieved.

[0026] Figures 1 to 6 An air guiding mechanism provided in this application embodiment is applied to an air conditioner. The air conditioner includes a duct housing 11, and the duct housing 11 has an airflow channel 11a. The air guiding mechanism includes a mounting component 1, a first air guide plate 3, and a second air guide plate 4. The mounting component 1 is used to connect to the duct housing 11. A main air duct 1a is opened in the mounting component 1, and the main air duct 1a is used to connect to the airflow channel 11a. A guide component 2 is provided in the main air duct 1a, and the guide component 2 divides the end of the main air duct 1a away from the airflow channel 11a into a first air duct 1b and a second air duct 1c arranged at an angle. Both the first air duct 1b and the second air duct 1c are connected to the main air duct 1a. The first air guide plate 3 is rotatably disposed on the first air duct 1b to cover or expose the first air duct 1b. The second air guide plate 4 is rotatably disposed on the second air duct 1c to cover or expose the second air duct 1c.

[0027] In this embodiment, the air guide mechanism is adapted to the air duct housing 11 of the air conditioner. Its mounting component 1 can be detachably connected to the air duct housing 11 by means of bolt fastening or snap-fit, so as to ensure stable installation and facilitate subsequent maintenance and replacement. The main air duct 1a inside the mounting component 1 can be cylindrical or square. The stable connection between the mounting component 1 and the air duct housing 11 ensures that the airflow can smoothly enter the main air duct 1a from the airflow channel 11a. The guide component 2 can be a guide plate or guide block integrally formed on the inner wall of the main air duct 1a. Its extension direction is consistent with the airflow direction of the main air duct 1a. It divides the end of the main air duct 1a away from the airflow channel 11a into a first air duct 1b and a second air duct 1c set at an angle. The angle can be set to 90° to adapt to the vertical layout of side air outlet and bottom air outlet, or it can be set to any angle between 45° and 120° to adapt to the air outlet requirements of different installation scenarios. The cross-sections of the first air duct 1b and the second air duct 1c can both be rectangular or circular. Their flow area is designed to be equal or adapted to different air outlet intensities according to the rated air volume of the air conditioner. Both the first air guide plate 3 and the second air guide plate 4 are made of plastic or aluminum alloy and are rotatably connected to the mounting part 1 via a rotating shaft. The rotating shaft can be driven by a stepper motor or a manual adjustment knob. When the first air guide plate 3 rotates around the rotating shaft to be perpendicular to the axis of the first air duct 1b, it completely blocks the first air duct 1b. When it rotates to be parallel to the axis of the first air duct 1b, it completely exposes the first air duct 1b. During the rotation, it can stop at any angle to adjust the airflow. The rotation adjustment method of the second air guide plate 4 is the same as that of the first air guide plate 3, realizing independent control of the blocking or exposure of the second air duct 1c. Furthermore, the surface of the air guide 2 can be provided with a smooth coating, such as a polytetrafluoroethylene coating, to reduce airflow resistance. Sealing strips can be provided on the edges of the first air guide plate 3 and the second air guide plate 4. When the air guide plate completely blocks the corresponding air duct, the sealing performance is improved to prevent air leakage. The mounting part 1 can be integrally injection molded from ABS engineering plastic. The inner walls of the main air duct 1a, the first air duct 1b, and the second air duct 1c are all smoothed to reduce airflow noise.

[0028] This air guiding mechanism divides the main air duct 1a into a first air duct 1b and a second air duct 1c at an angle by setting the air guide 2. With the independently rotating first air guide plate 3 and second air guide plate 4, it can realize multi-mode air outlet control. For example, in cooling mode, rotating the second air guide plate 4 to block the second air duct 1c and exposing the first air guide plate 3 to expose the first air duct 1b, so that the airflow exits to the side through the first air duct 1b. Taking advantage of the high density of cold air, it achieves "waterfall-style" uniform air supply, that is, air supply from top to bottom in cooling mode. In heating mode, rotating the first air guide plate 3 to block the first air duct 1b and exposing the second air guide plate 4 to expose the second air duct 1c, so that the airflow exits downward through the second air duct 1c, allowing the hot air to spread and cover the indoor space in a "carpet-like" manner, that is, air supply from bottom to top in cooling mode. It effectively solves the problem that the traditional single air outlet method cannot adapt to the density difference of cold and hot air. At the same time, it supports the partial or full opening of both the first air guide plate 3 and the second air guide plate 4 to achieve multi-angle and wide-area air supply, adapting to the usage needs of different users. The detachable connection design of mounting component 1 facilitates the assembly, maintenance, and replacement of the air guide mechanism. The integrated molding structure of the air guide component 2 and mounting component 1 enhances the overall structural stability and reduces vibration and noise caused by airflow impact. The independent adjustment function of the first air guide plate 3 and the second air guide plate 4 can precisely control the air outlet direction according to the indoor space layout and user activity area, avoiding discomfort from direct airflow. The sealing strip reduces air leakage loss and improves air conditioning energy efficiency. In addition, the material and structural design of mounting component 1 are compatible with the airflow channel 11a of different types of air conditioners (such as ducted air conditioners, cabinet air conditioners, etc.), which is highly versatile and does not require separate design for different air conditioner models, thus reducing production and manufacturing costs.

[0029] Please see Figure 1 and Figure 2 The guide member 2 has a first guide surface 21 and a second guide surface 22 arranged at an angle at one end near the main air duct 1a. The first guide surface 21 is located in the first air duct 1b, and the second guide surface 22 is located in the second air duct 1c.

[0030] In one embodiment, the guide member 2 has a first guide surface 21 and a second guide surface 22 integrally formed at one end near the main air duct 1a. The two are arranged at a preset angle and correspond to the airflow guiding paths of the first air duct 1b and the second air duct 1c, respectively. The first guide surface 21 and the second guide surface 22 can be set as smooth arc surfaces or inclined planes, and their extension direction is adapted to the airflow direction of the main air duct 1a to ensure that the airflow smoothly transitions to the corresponding first air duct 1b and the second air duct 1c. The angle between the two can be designed to be 90° according to the air outlet requirements to adapt to the vertical layout of side air outlet and bottom air outlet or any angle between 45° and 120°. By adjusting the air outlets corresponding to the first air duct 1b and the second air duct 1c, it can be adapted to other air supply scenarios, or adjusted to an asymmetrical angle according to the air duct flow area ratio to meet the air outlet intensity requirements of different air ducts. Specifically, the guide component 2 can be integrally injection molded from ABS engineering plastic or aluminum alloy. The surfaces of the first guide surface 21 and the second guide surface 22 can be coated with a low-friction coating such as polytetrafluoroethylene to reduce airflow resistance and noise. The edge of the first guide surface 21 smoothly transitions to the inner wall of the first air duct 1b, and the edge of the second guide surface 22 smoothly transitions to the inner wall of the second air duct 1c, preventing the formation of vortices at the connection between the guide surface and the inner wall of the air duct. Furthermore, the lengths of the first guide surface 21 and the second guide surface 22 can be adapted to the length of the corresponding air duct, or extended to the installation position close to the first air guide plate 3 and the second air guide plate 4, ensuring the guiding effect on the airflow throughout the entire process and improving the stability of the airflow.

[0031] The first guide surface 21 and the second guide surface 22 can accurately divert the airflow in the main air duct 1a to the first air duct 1b and the second air duct 1c, avoiding problems such as airflow turbulence and backflow at the diversion point, thus improving air outlet efficiency. They also adapt to the density differences between hot and cold air. When the air conditioner is cooling, the airflow is guided by the first guide surface 21 to the side of the first air duct 1b, with the cold air descending evenly in a "waterfall" pattern. When the air conditioner is heating, the airflow is guided by the second guide surface 22 to the bottom of the second air duct 1c, with the hot air spreading out in a "carpet" pattern, effectively solving the problem of poor comfort in traditional single air outlet methods. The smooth guide surface design reduces airflow resistance and noise. Combined with the smooth transition between the guide surface and the inner wall of the air duct, it further reduces vibration and wind noise generated by airflow impact, improving the quietness of air conditioner operation. The different angle designs can adapt to various air duct layouts and air outlet requirements, enhancing the versatility of the air guide mechanism. It eliminates the need for separate design of guide structures for different air conditioner models, reducing manufacturing costs.

[0032] Please see Figures 1 to 3 The air guiding mechanism also includes a sweeping assembly 5, which is located in the main air duct 1a. The sweeping assembly 5 includes a sweeping component 51 and a connecting component 52. The connecting component 52 is connected to the mounting component 1, and the sweeping component 51 is rotatably mounted on the connecting component 52.

[0033] In this embodiment, the sweeping assembly 5 is assembled within the main air duct 1a and located in the connection area between the guide member 2 and the first air duct 1b and the second air duct 1c, ensuring that the sweeping action can cover the two airflows after diversion. The connecting member 52 can be specifically configured as a bracket, a rotating shaft seat, or a snap-fit ​​seat, and is fixedly connected to the mounting member 1 by bolt fastening, welding, or integral injection molding. Its structure must adapt to the internal spatial layout of the main air duct 1a and not affect the normal flow of airflow. The connecting member 52 is provided with a bearing or shaft hole structure for cooperating with the rotational assembly of the sweeping component 51. The sweeping component 51 adopts a blade-type structure, and its main body can be made of plastic or aluminum alloy. The middle part of the sweeping component 51 is rotatably engaged with the bearing or shaft hole of the connecting member 52 via a rotating shaft. The rotating shaft can be connected to a stepper motor to achieve automatic reciprocating rotation, or equipped with a manual adjustment knob for the user to manually control the rotation angle. Reinforcing ribs can be provided at the connection position between the connecting member 52 and the mounting member 1 to improve the structural stability of the sweeping assembly 5 and prevent vibration when the sweeping component 51 rotates.

[0034] The design of the air-sweeping assembly 5 optimizes airflow uniformity and delivery experience. The air-sweeping component 51 can simultaneously sweep the airflow in the first air duct 1b and the second air duct 1c. Combined with the reciprocating rotation of the air-sweeping component 51, it ensures that the two airflows form uniform sweeping trajectories, avoiding excessively strong localized airflow or dead zones. It is particularly suitable for various modes such as cooling side airflow, heating bottom airflow, and dual airflow, resulting in a more uniform indoor temperature distribution. The robust connection design between the connector 52 and the mounting component 1 ensures the stability of the air-sweeping component 51 during rotation, reducing vibration and noise, and improving the quietness of air conditioning operation.

[0035] Please see Figures 1 to 3 The air-sweeping component 51 includes a first air-sweeping section 511 and a second air-sweeping section 512 arranged at an angle. At most part of the first air-sweeping section 511 is located in the first air duct 1b, and at most part of the second air-sweeping section 512 is located in the second air duct 1c.

[0036] In one embodiment, the first sweeping section 511 and the second sweeping section 512 of the sweeping member 51 are integrally formed structures, made of lightweight and high-strength materials such as plastic, aluminum alloy, or carbon fiber. They form a preset angle between them to adapt to the layout of the first air duct 1b and the second air duct 1c. This angle can be set to 90° to adapt to vertical air duct designs with side and bottom air outlets, or other angles adapted to the first air duct 1b and the second air duct 1c. At most part of the first sweeping section 511 is located within the first air duct 1b, and its length is less than the length of the first air duct 1b, and its width is less than the cross-sectional width of the first air duct 1b, ensuring that it does not interfere with the inner wall of the first air duct 1b or the first air guide plate 3 during sweeping. At most part of the second sweeping section 512 is located within the second air duct 1c, and its structural design is the same as that of the first sweeping section 511. During the rotation of the air-sweeping component 51, the first air-sweeping section 511 and the second air-sweeping section 512 rotate synchronously, respectively guiding the airflow in the first air duct 1b and the second air duct 1c. The edges of the first air-sweeping section 511 and the second air-sweeping section 512 can be provided with rounded corner structures to avoid airflow impact and generate vortices, thereby improving the smoothness of airflow.

[0037] The first sweeping section 511 and the second sweeping section 512 act on the first air duct 1b and the second air duct 1c respectively, enabling simultaneous sweeping of the two airflows. Combined with the mode switching of the air guide plate, such as side-discharge for cooling, bottom-discharge for heating, or dual-discharge, this ensures a more even distribution of cold air in a "waterfall-like" manner and hot air in a "carpet-like" manner, effectively eliminating indoor temperature stratification and dead air zones. Different angle designs can adapt to various air duct layouts, enhancing the versatility of the sweeping component 51 and eliminating the need for separate designs for different duct air conditioner models. The one-piece molded sweeping section structure improves the structural strength and stability of the sweeping component 51, while the lightweight material and smooth surface design reduce airflow resistance and operating noise, enhancing the quietness of the duct air conditioner.

[0038] Please see Figures 1 to 3In this embodiment, the angle between the first sweeping section 511 and the second sweeping section 512 is set to be no less than the angle between the first guide surface 21 and the second guide surface 22. The fit between the two angles is designed according to the duct layout and air outlet requirements. For example, if the angle between the first guide surface 21 and the second guide surface 22 is 90°, then the angle between the first sweeping section 511 and the second sweeping section 512 can be set to 90° or 100°-120°; if the angle between the first guide surface 21 and the second guide surface 22 is 60°, then the angle between the first sweeping section 511 and the second sweeping section 512 can be set to 60° or 70°-90°. The first sweeping section 511 and the second sweeping section 512 are integrally formed structures, and the angle is formed by injection molding or machining to ensure that the sweeping trajectory can completely cover the airflow output range of the first duct 1b and the second duct 1c. When assembling the air-sweeping component 51, the bifurcation centers of the two air-sweeping sections are aligned with the intersection points of the first guide surface 21 and the second guide surface 22. This ensures that the airflow, after being diverted by the guide surfaces, can directly enter the sweeping area of ​​the air-sweeping section, avoiding uneven sweeping caused by airflow deviation. The length of the air-sweeping section can be adjusted adaptively according to the included angle. When the included angle is larger, the length of the air-sweeping section should be appropriately shortened to prevent interference with the inner wall of the air duct or the guide plate during sweeping.

[0039] The angle of the swept section is no less than that of the guide surface, ensuring that both airflows after being split by the guide surface are completely covered by the swept section, avoiding blind spots. Simultaneously, the rotation of the swept section creates a wider swept range, allowing for uniform diffusion of airflow from the side outlet of the first duct 1b, the bottom outlet of the second duct 1c, and in dual-outlet mode. This effectively solves the indoor temperature stratification problem caused by insufficient coverage in traditional single-outlet systems, improving comfort. The angle-adaptive design ensures a smoother transition of airflow from the guide surface to the swept section, reducing eddies and resistance caused by airflow impact, lowering operating noise, and avoiding interference risks between the swept section and the ducts and guide vanes, thus improving structural stability.

[0040] Please see Figure 2 and Figure 4 The first air guide plate 3 has a first air guide section 31 at the end away from the main air duct 1a, and the side wall of the first air guide section 31 can abut against the inner wall of the first air duct 1b; the second air guide plate 4 has a second air guide section 41 at the end away from the main air duct 1a, and the side wall of the second air guide section 41 can abut against the inner wall of the second air duct 1c.

[0041] In one embodiment, the first air guide plate 3 has a first air guide portion 31 integrally formed at the end away from the main air duct 1a, and the second air guide plate 4 has a second air guide portion 41 integrally formed at the end away from the main air duct 1a. Both the first air guide portion 31 and the second air guide portion 41 are made of the same plastic or aluminum alloy material as the main body of the air guide plate to ensure structural strength and molding consistency. The side wall of the first air guide portion 31 is set as an arc-shaped surface or plane adapted to the inner wall of the first air duct 1b, and its size is designed according to the cross-sectional contour of the first air duct 1b. When the first air guide plate 3 is rotated to the position that completely blocks the first air duct 1b, the side wall of the first air guide portion 31 can fully abut against the inner wall of the first air duct 1b. Similarly, the side wall of the second air guide portion 41 is set as an arc-shaped surface or plane adapted to the inner wall of the second air duct 1c. When the second air guide plate 4 completely blocks the second air duct 1c, the side wall of the second air guide portion 41 fully abuts against the inner wall of the second air duct 1c. Furthermore, sealing strips can be attached to the side walls of the first air guide section 31 and the second air guide section 41, or an elastic sealing coating can be sprayed on them to improve the sealing performance when they come into contact. During the rotation of the air guide plate, the air guide section rotates synchronously with the air guide plate. When the air duct is exposed, the air guide section can work with the air guide plate body to guide the airflow direction and improve the smoothness of the airflow.

[0042] When the first air guide plate 3 or the second air guide plate 4 is closed, the side wall of the air guide part is tightly abutted against the inner wall of the air duct, which can effectively block the airflow of the corresponding air duct and avoid air leakage. This ensures that the airflow in the cooling mode is completely discharged from the side of the first air duct 1b and the airflow in the heating mode is completely discharged from the bottom of the second air duct 1c, ensuring the accuracy of air outlet in different modes. At the same time, the addition of sealing strips or elastic coatings further improves the sealing effect and reduces energy loss. The air guide part and the air guide plate body are integrally formed, which not only enhances the overall structural strength of the air guide plate, but also guides the airflow in a coordinated manner when the air guide plate is open, so that the airflow flows smoothly out along the inner wall of the air duct and improves the uniformity of air outlet.

[0043] Please see Figure 2 and Figure 4 The first air guide plate 3 has a first connecting part 32 and a first auxiliary air guide part 33 at one end near the main air duct 1a. The first connecting part 32 connects the first auxiliary air guide part 33 and the first air guide part 31. The second air guide plate 4 has a second connecting part 42 and a second auxiliary air guide part 43 at one end near the main air duct 1a. The second connecting part 42 connects the second auxiliary air guide part 43 and the second air guide part 41.

[0044] In this embodiment, the first air guide plate 3, near the main air duct 1a, is integrally formed into a first connecting part 32 and a first auxiliary air guide part 33. All three are made of lightweight, high-strength materials such as plastic or aluminum alloy to ensure structural integrity and stability. The first connecting part 32 is a plate-shaped or columnar structure, with one end connected to the first air guide part 31 and the other end fixedly connected to the first auxiliary air guide part 33. The connection can be integrally formed by injection molding or mechanical fastening. The first auxiliary air guide part 33 is an arc-shaped plate or an inclined flat plate structure. Its extension direction is adapted to the airflow direction of the first air duct 1b and matches the inclination angle of the first guide surface 21. When the first air guide plate 3 is opened, the first auxiliary air guide part 33 can further guide the airflow after it is diverted in the first air duct 1b. Similarly, the second connecting part 42 and the second auxiliary air guide part 43 of the second air guide plate 4 adopt the same material and molding process as the first air guide plate 3. The second connecting part 42 realizes a stable connection between the second auxiliary air guide part 43 and the second air guide part 41. The structure of the second auxiliary air guide part 43 is adapted to the airflow direction of the second air duct 1c and the tilt angle of the second guide surface 22. The side walls of the first connecting part 32 and the second connecting part 42 can be provided with reinforcing ribs to improve the overall structural strength of the air guide plate and avoid deformation caused by airflow impact.

[0045] The first auxiliary air guide section 33 and the second auxiliary air guide section 43 further assist in guiding the airflow of the corresponding air ducts, so that the airflow is more smoothly discharged from the first air duct 1b or the second air duct 1c, avoiding the formation of vortices at the air outlet and improving the air outlet efficiency and uniformity. The connecting part achieves a stable connection between the auxiliary air guide section and the air guide section through an integrated design, which not only enhances the overall structural strength of the air guide plate and avoids breakage and deformation caused by long-term use or airflow impact, but also simplifies the processing and assembly process.

[0046] Please see Figure 1 and Figure 2 In one embodiment, both the first air duct 1b and the second air duct 1c are equipped with mesh covers 6. The mesh covers 6 in both the first air duct 1b and the second air duct 1c are made of wire mesh, stainless steel filter mesh 14, or high-strength plastic mesh. The mesh size can be designed from 20 to 80 meshes according to filtration requirements, ensuring smooth airflow while achieving effective dust removal. The mesh cover 6 has a rectangular or circular structure adapted to the cross-section of the corresponding air duct. Its edges are fixed to the inner wall of the air duct by snap-fit, bolt fastening, or integral injection molding, and its installation position is close to the air outlet side. Specifically, the mesh covers 6 of the first air duct 1b and the second air duct 1c can be designed as detachable structures, engaging with the air outlet frame of the first air duct 1b via circumferentially arranged snap-fits, facilitating periodic disassembly and cleaning. Furthermore, the edges of the mesh cover 6 can be provided with a flanged structure to enhance the fit with the inner wall of the air duct, preventing displacement of the mesh cover 6 due to airflow impact. A cushioning pad can also be attached to the flanged area to reduce vibration noise during operation.

[0047] The mesh cover 6 enables secondary electrostatic dust removal. Combined with the PP fine mesh material at the air inlet and the high-efficiency filter 14 inside the air outlet, it forms a three-stage filtration system. This effectively intercepts large particulate pollutants such as dust and willow catkins in the air, preventing them from entering the air duct and clogging the evaporator 13 or adhering to the air guide plate and sweeping assembly 5. This avoids mold and odor, ensures clean airflow, and extends the service life of internal air conditioning components. The mesh cover 6 also provides protection and support, preventing foreign objects from accidentally entering the air duct and damaging moving parts such as the sweeping blades and air guide plate, thus improving equipment operational safety. Its detachable and fixed lower design adapts to different air duct installation requirements, enhancing structural flexibility.

[0048] Secondly, please refer to Figure 1 , Figure 5 as well as Figure 6 This application provides an air conditioner, including a housing 10, a duct housing 11, a fan 12, an evaporator 13, and an air guiding mechanism provided in the first aspect of this application. The housing 10 has an installation cavity 10a. The housing 10 has a first air outlet 10b, a second air outlet 10c, and an air inlet 10d communicating with the installation cavity 10a. The first air outlet 10b is located on the side wall of the housing 10, the second air outlet 10c is located on the bottom wall of the housing 10, and the air inlet 10d is located on the side wall or the bottom wall of the housing 10. The first air duct 1b communicates with the first air outlet 10b, and the second air duct 1c communicates with the second air outlet 10c. The duct housing 11 is disposed in the installation cavity 10a, and the duct housing 11 has an airflow channel 11a. The two ends of the airflow channel 11a are respectively connected to the air inlet 10d and the main air duct 1a. The fan 12 is disposed in the airflow channel 11a. The evaporator 13 is disposed between the air inlet 10d and the fan 12.

[0049] In this embodiment, the air conditioner's outer casing 10 is integrally molded from sheet metal or engineering plastic, forming an internal mounting cavity 10a. A first air outlet opening 10b is provided on the side wall of the outer casing 10 to accommodate side airflow, and a second air outlet opening 10c is provided on the bottom wall to accommodate bottom airflow. An air inlet opening 10d is provided on the other side wall or bottom wall of the outer casing 10 according to installation requirements. Each opening edge is provided with a sealing groove for sealing connection with the corresponding component. The duct housing 11 is made of flame-retardant ABS plastic and is fixed to the mounting cavity 10a by bolts or snap-fit ​​connections. Its internal airflow channel 11a has an arc-shaped or straight structure. One end of the airflow channel 11a is connected to the air inlet opening 10d via a pipe or flange, and the other end is connected to the main air duct 1a of the air guide mechanism to ensure smooth airflow. The fan 12 can be a cross-flow fan 12, fixed in the airflow channel 11a by a bracket, with its output end facing the main air duct 1a, to provide power for airflow. The evaporator 13 has an arc-shaped bent structure, arranged around the fan 12 or fixed in the airflow channel 11a between the air inlet opening 10d and the fan 12. The wiring terminals of the evaporator 13 are electrically connected to the air conditioning control system to achieve cooling or heating of the airflow. The first air duct 1b is connected to the first air outlet opening 10b through a pipe, and the second air duct 1c is connected to the second air outlet opening 10c through a pipe, ensuring that the airflow after being diverted by the air guiding mechanism can be accurately output from the corresponding air outlet opening. The lower cover and front panel of the outer casing 10 are both connected by detachable snap-fit, which facilitates subsequent maintenance of internal components.

[0050] This air conditioner utilizes a dual-air duct and dual-air guide plate design in its air guiding mechanism, combined with a dual-air outlet layout on the outer casing 10. In cooling mode, the first air outlet 10b is for side airflow, allowing cold air to "cascade" downwards; in heating mode, the second air outlet 10c is for bottom airflow, allowing hot air to "carpet" out. This adapts to the density differences between cold and hot air, solving the comfort issues caused by the single air outlet of traditional air conditioners. It also supports simultaneous airflow from both outlets, meeting wide-area air delivery needs. The air inlet 10d can be flexibly placed on the side or bottom wall, accommodating both side and bottom air inlet modes. Combined with the dual-air outlet design, this allows the air conditioner to adapt to different indoor layouts and installation scenarios, enhancing installation versatility.

[0051] Please see Figure 1 , Figure 5 as well as Figure 6 A filter 14 is provided at the air inlet opening 10d, and the filter 14 is located between the air inlet opening 10d and the evaporator 13.

[0052] In one embodiment, the filter 14 at the air inlet 10d is made of cleanable PP fine mesh material, and is paired with a mesh frame adapted to the contour of the air inlet 10d to form a modular filter 14 assembly. It can be detachably installed between the air inlet 10d and the evaporator 13 by means of snap-fit, sliding rail pull-out, or bolt fastening, ensuring a stable installation and easy disassembly and maintenance, preventing airflow impact from causing the filter 14 to shift. The mesh density of the filter 14 is designed according to filtration requirements; a high-density PP fine mesh can be selected to intercept pollutants such as dust, willow catkins, and PM2.5. The surface of the filter 14 can be treated with electrostatic adsorption to enhance the filtration effect. The mesh frame is made of ABS engineering plastic in one piece, with sealing rings at the edges to ensure a seamless fit between the filter 14 and the inner wall of the airflow channel 11a, preventing unfiltered air from flowing in through gaps.

[0053] The filter 14 is located between the air inlet 10d and the evaporator 13. It performs primary filtration of the airflow entering the air conditioner, effectively intercepting pollutants in the air and preventing dust, catkins, etc., from clogging the evaporator 13 pipes or adhering to its surface. This prevents the evaporator 13 from becoming moldy and producing odors, ensuring the heat exchange efficiency and service life of the evaporator 13. At the same time, it outputs clean air to the room, improving the user experience. The modular and detachable design makes the filter 14 easy to clean or replace regularly. Users can directly pull out or remove the filter 14 assembly, clean and dry it, and then reinstall it, making maintenance convenient and reducing operating costs. The matching design of the filter 14 with the air inlet 10d and the airflow channel 11a ensures smooth air intake without adding extra airflow resistance, ensuring the air conditioning's output efficiency. The sealing ring avoids filtration blind spots, improving the comprehensiveness of filtration.
