Fresh air system components, indoor air conditioning units and air conditioners

Abstract

This disclosure relates to a fresh air assembly, an indoor air conditioning unit, and an air conditioner. The fresh air assembly includes a fresh air housing and a filter structure. The fresh air housing has a fresh air flow channel. The filter structure is disposed within the fresh air flow channel and is curved, having a curved convex surface facing and / or away from the fresh air flow direction. In this solution, the curved convex surface of the filter structure facing and / or away from the fresh air direction increases the surface area of ​​the filter structure, i.e., increases the windward area of ​​the filter structure, thereby improving the filtration efficiency of the filter structure for fresh air. Simultaneously, compared to a straight filter structure, the curved filter structure can increase the windward area within a limited space, overcoming the spatial limitations of a planar layout. Under the same fresh air flow channel volume, it significantly increases the contact area between the filter material and the airflow. The larger contact area also allows the airflow to pass through the filter structure more evenly, avoiding filtration blind spots caused by excessively fast local airflow in planar filtration.

[0002] To improve user comfort, the indoor unit of the air conditioner has been equipped with a fresh air function, which introduces fresh air from the outside to the inside through the fresh air module to improve indoor air quality.

[0003] However, in related technologies, fresh air filters are usually designed in a straight line, with a limited frontal area, and the filtration efficiency for fresh air needs to be improved. Utility Model Content

[0011] In some embodiments, the filter structure is located on one side of the fan along its axial direction.

[0012] In some embodiments, the filter structure is located on one side of the fan in the radial direction.

[0013] In some embodiments, two filter structures are provided along the axial direction of the fan.

[0014] In some embodiments, the filter structure is bent toward or away from the fan, or the filter structure is tilted opposite to the fresh air inlet.

[0015] In some embodiments, the filter structure is arranged in an arc-shaped bend.

[0016] In some embodiments, the filter structure is detachably mounted on the fresh air housing.

[0017] In some embodiments, the fresh air housing is provided with an installation port for the filter structure to extend into the fresh air flow channel, and one end of the filter structure is provided with a sealing head, which seals the installation port after the filter structure extends into the fresh air flow channel from the installation port.

[0018] In some embodiments, the sealing head is located at least partially outside the mounting port when sealing the mounting port.

[0019] In some embodiments, the inner wall of the fresh air duct is provided with a slot, and the filter structure is slidably engaged in the slot.

[0020] In some embodiments, the fresh air housing includes a first housing and a second housing fixed to each other, the first housing and the second housing clamping the filter structure.

[0021] In some embodiments, the filter structure is detachably installed between the first housing and the second housing;

[0022] The first housing has a first opening, and the second housing has a second opening. The first opening and the second opening are combined to form an installation port, which allows the filter structure to extend into the fresh air flow channel.

[0023] Secondly, this application also provides an indoor air conditioning unit, comprising:

[0024] The casing has an air outlet and a disassembly port; and

[0025] As described in any of the preceding claims, the fresh air housing of the fresh air assembly is disposed in the housing and adjacent to the disassembly port, and the filter structure of the fresh air assembly is detached from or extends into the fresh air flow channel through the disassembly port.

[0026] In some embodiments, the fresh air housing and the disassembly port are located at the same end in the direction of the air outlet extension.

[0027] In some embodiments, the indoor unit of the air conditioner further includes an air guide plate, which is movably installed on the housing and has an extreme position to avoid the air outlet;

[0028] Wherein, the air guide plate avoids the disassembly port when it is at the extreme position, and does not interfere with the travel trajectory of the filter structure when it is disassembled and assembled into the fresh air housing.

[0029] In some embodiments, when the air guide plate is in the extreme position, the air guide plate guides the airflow at the air outlet downward or upward.

[0030] In some embodiments, the indoor unit of the air conditioner further includes a rotating arm, which is rotatably connected to the housing and rotatably connected to the air guide plate.

[0034] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects: In this solution, the filter structure has a curved convex surface facing and / or away from the fresh air direction, which increases the surface area of ​​the filter structure, that is, increases the windward area of ​​the filter structure, and improves the filtration efficiency of the filter structure for fresh air.

[0035] Meanwhile, compared to a straight filter structure, the curved filter structure can increase the frontal area within a limited space, breaking through the spatial limitations of a planar layout. This significantly increases the contact area between the filter material and the airflow within the same fresh air duct volume. The larger contact area also allows the airflow to pass through the filter structure more evenly, avoiding filtration blind spots caused by excessively fast local airflow in planar filtration.

[0036] Furthermore, the curved filter structure can be directly adapted to curved air ducts, circular fans, etc., reducing the number of duct bends and avoiding spatial conflicts between the filter structure and other components (such as circuit boards and motors), thus reducing the overall design complexity of the equipment. The curved design can also flexibly fit the curved surfaces inside the equipment (such as circular air ducts and curved shells), making full use of corner spaces and improving space utilization.

[0056] Some embodiments of this disclosure will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. Various changes, modifications, and equivalents of the methods, apparatus, and / or systems described herein will become apparent upon understanding this disclosure. For example, the order of operations described herein is merely illustrative and is not limited to those orders set forth herein, but can be changed as will become apparent upon understanding this disclosure, except for operations that must be performed in a particular order. Furthermore, for clarity and brevity, descriptions of features known in the art may be omitted.

[0057] The embodiments described in the following examples of this disclosure are not representative of all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0058] To improve user comfort, air conditioner indoor units are often equipped with a fresh air function, introducing fresh air from outdoors to indoors via a fresh air module to improve indoor air quality. However, in related technologies, the fresh air filter is usually designed as a straight line, with a limited airflow area, and its filtration efficiency for fresh air needs to be improved.

[0059] To address the technical problem that fresh air filters in related technologies are typically designed as straight lines with limited frontal area, resulting in insufficient filtration efficiency for fresh air, this application provides a fresh air assembly, an indoor air conditioning unit, and an air conditioner. The filter structure has a curved convex surface facing and / or away from the fresh air direction, which increases the surface area of ​​the filter structure, thereby increasing the frontal area of ​​the filter structure and improving the filtration efficiency for fresh air.

[0060] Please see Figures 1 to 3 The fresh air assembly provided in this disclosure includes a fresh air housing 2 and a filter structure 3; the fresh air housing 2 has a fresh air flow channel 2a; the filter structure 3 is disposed in the fresh air flow channel 2a and is curved, and has a curved convex surface that is oriented toward and / or away from the fresh air flow direction.

[0061] In this design, the filter structure 3 has a curved convex surface facing and / or away from the direction of the fresh air, increasing its surface area and thus its frontal area, thereby improving its filtration efficiency for fresh air. Furthermore, compared to a straight filter structure, the curved filter structure 3 can increase the frontal area within a limited space, overcoming the spatial limitations of a planar layout. Under the same fresh air flow channel 2a volume, this significantly increases the contact area between the filter material and the airflow. The larger contact area also allows the airflow to pass through the filter structure 3 more evenly, avoiding filtration blind spots caused by excessively fast local airflow in planar filtration.

[0062] Furthermore, the curved filter structure 3 can be directly adapted to curved air ducts, circular fans 6, etc., reducing the number of duct bends and avoiding spatial conflicts between the filter structure 3 and other components (such as circuit boards and motors), thus reducing the overall design complexity of the equipment. The curved design also allows for flexible fitting of curved surfaces within the equipment (such as circular air ducts and curved shells), making full use of corner spaces and improving space utilization.

[0063] It should be noted that the filter structure 3 can be configured as a filter screen, filter cotton, non-woven fabric, or filter paper combined with a support frame, or other forms, as long as it can achieve fresh air filtration. Specifically, in this solution, the filter structure 3 includes a filter frame and a filter screen. The filter frame is installed in the fresh air flow channel 2a of the fresh air housing 2, and has a curved convex surface facing and / or away from the fresh air flow direction. The filter screen is installed on the filter frame.

[0064] In one embodiment, please refer to Figure 3 and Figure 4 The fresh air duct 2a has a fresh air inlet 2c, and the fresh air assembly also includes a fan 6. The fan 6 is located in the fresh air duct 2a and has a fresh air outlet 6a. The filter structure 3 is located between the fresh air inlet 2c and the fan 6. The fan 6 is used to guide the fresh air from the fresh air inlet 2c through the filter structure 3 to the fresh air outlet 6a.

[0065] In this embodiment, the fresh air inlet 2c is connected to the external environment through a duct. During the rotation of the fan 6, the outside air is guided from the fresh air inlet 2c to the fresh air outlet 6a, and finally enters the room. The fresh air is filtered by the filter structure 3 during its flow to ensure that the fresh air delivered into the room is clean.

[0066] In one embodiment, please refer to Figure 5 The fan 6 is a centrifugal fan, and the fan 6 is spaced apart from the inner wall of the fresh air flow channel 2a on at least one side in the axial direction.

[0067] In this embodiment, the fan 6 is configured as a centrifugal fan, with axial air intake and radial air exhaust. Therefore, at least one side of the fan 6 along its axial direction is spaced apart from the inner wall of the fresh air duct 2a to ensure normal air intake. Specifically, in this design, both sides of the fan 6 along its axial direction are spaced apart from the inner wall of the fresh air duct 2a, allowing simultaneous air intake from both sides of the fan 6 along its axial direction, thus improving air delivery efficiency.

[0068] In one embodiment, the filter structure 3 is located on one side of the fan 6 in the axial direction.

[0069] In this embodiment, the filter structure 3 and the fan 6 are arranged sequentially along the axial direction of the fan 6, so that the fresh air, after passing through the filter structure 3, directly points to the axial air intake side of the fan 6, shortening the fresh air travel distance, improving airflow efficiency, and reducing energy consumption. It should be noted that in this embodiment, the axial direction of the fan 6 is the same as the extension direction of the air outlet 1a. It should be understood that the extension direction of the air outlet 1a refers to its length direction.

[0070] It should be noted that the radial dimension of the fan 6 is usually smaller than that of the casing 1, that is, there is usually a certain space between the fan 6 and the inner wall of the casing 1 in the radial direction.

[0071] Therefore, in one embodiment, the filter structure 3 is located on one side of the fan 6 in the radial direction.

[0072] In this embodiment, the filter structure 3 and the fan 6 are arranged radially along the fan 6, making full use of the space between the fan 6 and the inner wall of the casing 1 in the radial direction, avoiding additional occupation of the space of the casing 1 in the axial direction of the fan 6, making the indoor unit of the air conditioner relatively compact and reducing the size of the casing 1. Similarly, in this solution, the axial direction of the fan 6 is the same as the extension direction of the air outlet 1a. And the filter structure 3 is located on the lower side of the fan 6, arranged sequentially with the fan 6 in the vertical direction.

[0073] In one embodiment, two filter structures 3 are arranged along the axial direction of the fan 6.

[0074] In this embodiment, a filter structure 3 is respectively provided on the air inlet side at both ends of the fan 6, so that the two air inlet sides of the fan 6 correspond one-to-one with the two filter structures 3, thereby improving the fresh air filtration efficiency and ensuring the cleanliness of the fresh air entering the room. It should be noted that, in one embodiment, when two filter structures 3 are provided, the two filter structures 3 can be installed as a single unit and can be disassembled and assembled via a mounting port 2b. In another embodiment, when two filter structures 3 are provided, two mounting ports 2b are correspondingly provided, located at the same end of the air outlet, and corresponding one-to-one with the two filter structures 3.

[0075] In one embodiment, the filter structure 3 is bent toward or away from the fan 6, or, see [link to relevant documentation] Figure 3 and Figure 6 The filter structure 3 is set at an angle relative to the fresh air inlet 2c.

[0076] In this embodiment, when the filter structure 3 is bent, its frontal area increases, thereby improving the fresh air filtration efficiency. When the filter structure 3 bends towards the fan 6, the fresh air, after entering the fresh air flow channel 2a from the fresh air inlet 2c, first contacts the concave surface of the filter structure 3. At this time, the filter structure 3 has the function of converging the fresh air, accelerating the fresh air flow rate, allowing the fresh air to quickly pass through the filter structure 3 and flow towards the fan 6, improving the fresh air filtration efficiency. Conversely, when the filter structure 3 bends away from the fan 6, the fresh air, after entering the fresh air flow channel 2a from the fresh air inlet 2c, first contacts the convex surface of the filter structure 3. At this time, the filter structure 3 has the function of guiding the diffusion of the fresh air, making the fresh air diffuse evenly, reducing airflow impact and turbulence, lowering the overall wind resistance, and thus allowing the fresh air to contact all parts of the filter structure 3 evenly, improving the fresh air purification capacity. Furthermore, when the filter structure 3 bends away from the fan 6, a space is formed on the side near the fan 6, which can be used to install the fan 6, improving space utilization.

[0077] Furthermore, in one embodiment, the filter structure 3 is inclined relative to the fresh air inlet 2c, allowing the filter structure 3 to expand its effective filtration area within a limited space. Simultaneously, when the filter structure 3 is inclined as described above, it guides the fresh air to flow along the inclined surface of the filter structure 3. At this time, the fresh air passes smoothly through the filter structure 3 along the inclined angle, reducing energy loss caused by airflow rebound and eddies, reducing airflow impact, and thus reducing operating noise.

[0078] Furthermore, the tilt angle allows gravity to assist in the deposition of impurities. Some larger particles (such as dust and hair) will slide down the filter surface to the dust collection area below due to gravity after contacting the tilted filter under the action of airflow, thus preventing impurities from clogging the air pores on the filter surface.

[0079] In one embodiment, the filter structure 3 is arranged in an arc-shaped bend.

[0080] In this embodiment, the relatively smooth surface of the arc-shaped filter structure 3 can disperse the force, allowing fresh air to flow smoothly along the arc-shaped surface, significantly reducing resistance and energy consumption. Specifically, when fresh air or water comes into contact with the arc-shaped surface, it will naturally conform to the curved surface, avoiding rebound and eddies caused by impacting flat surfaces or sharp angles, thus reducing fluid resistance. Reduced resistance can directly reduce the energy demand for driving the fluid, while also reducing operating noise.

[0081] Furthermore, the outer surface of the arc-shaped filter has no obvious dead corners, and users can clean impurities along the curved surface in one go when cleaning with a brush or vacuum cleaner; some washable filters are also easier to rinse due to their arc-shaped structure, reducing blind spots in cleaning.

[0082] In one embodiment, the filter structure 3 is detachably installed on the fresh air housing 2.

[0083] In this embodiment, the filter structure 3 can be periodically removed from the fresh air housing 2 for cleaning or replacement maintenance, and then the maintained filter structure 3 can be installed back onto the fresh air housing 2 to ensure the filtration effect on the fresh air. It should be noted that the filter structure 3 and the fresh air housing 2 can be detachably connected by elastic clips, bolts, or magnets, etc., and this is not limited here.

[0084] In one embodiment, please refer to Figure 2 , Figure 3 and Figure 7 The fresh air housing 2 is provided with an installation port 2b for the filter structure 3 to extend into the fresh air flow channel 2a. One end of the filter structure 3 is provided with a sealing head 31, which seals the installation port 2b after the filter structure 3 extends into the fresh air flow channel 2a from the installation port 2b.

[0085] In this embodiment, when installing the filter structure 3, it is introduced into the fresh air duct 2a through the installation port 2b until the sealing head 31 seals the installation port 2b, ensuring the airtightness of the fresh air duct 2a and preventing unfiltered fresh air from directly diffusing into the room through the installation port 2b. When it is necessary to disassemble the filter structure 3, the sealing head 31 is pulled out of the fresh air duct 2a through the installation port 2b in sequence.

[0086] In one embodiment, the sealing head 31 is at least partially located outside the mounting opening 2b when sealing the mounting opening 2b.

[0087] In this embodiment, after the filter structure 3 is installed into the fresh air duct 2a, the sealing head 31 of the filter structure 3 is located outside the installation port 2b, making it easy for the user to remove and disassemble, thus improving convenience. It should be noted that in one embodiment, the sealing head 31 is made of rubber material, or the outer periphery of the sealing head 31 is covered with rubber material to ensure the sealing performance of the sealing head 31 to the installation port 2b. Furthermore, the surface of the rubber material is provided with anti-slip grooves or anti-slip protrusions to prevent detachment.

[0088] It should be noted that the filter structure 3 and the fresh air housing 2 can be detachably connected by bolts, elastic clips or magnetic attraction.

[0089] In one embodiment, the inner wall of the fresh air duct 2a is provided with a slot 2d, and the filter structure 3 is slidably engaged in the slot 2d.

[0090] In this embodiment, when the filter structure 3 is installed or removed from the fresh air duct 2a, it can be guided to slide via the slot 2d, ensuring a stable connection between the filter structure 3 and the fresh air housing 2. Specifically, in this solution, the slot 2d is arranged in an arc-shaped bend corresponding to the filter structure 3.

[0091] In one embodiment, please refer to Figure 7The fresh air housing 2 includes a first housing 21 and a second housing 22 that are fixed to each other, and the first housing 21 and the second housing 22 clamp the filter structure 3.

[0092] In this embodiment, the fresh air housing 2 is assembled from a first housing 21 and a second housing 22. The individual housing structure is relatively regular, allowing for simpler molds and reducing the development cost and processing difficulty of complex one-piece molds, while also lowering the scrap rate during production. This also facilitates the pre-assembly of components such as the fan 6 and filter structure 3 between the first housing 21 and the second housing 22 before overall assembly, improving assembly efficiency. It should be noted that the first housing 21 and the second housing 22 can be connected using snap-fit, bolt, or tenon joints.

[0093] In one embodiment, the filter structure 3 is detachably installed between the first housing 21 and the second housing 22; the first housing 21 has a first opening 21a, the second housing 22 has a second opening 22a, the first opening 21a and the second opening 22a are combined to form an installation port 2b, the installation port 2b allows the filter structure 3 to extend into the fresh air flow channel 2a.

[0094] In this embodiment, the mounting port 2b is formed by the openings of the two housings, avoiding the reduction of the housing structure strength and stress concentration caused by opening a complete mounting port 2b on a single housing. After the first housing 21 and the second housing 22 are joined, the filter structure 3 can detach from the mounting port 2b formed by the two housings or extend into the fresh air flow channel 2a. It should be noted that a sealing ring is provided between the first housing 21 and the second housing 22.

[0095] In addition, please see Figures 8 to 10 This disclosure also provides an indoor air conditioning unit, including a housing 1 and a fresh air assembly as described above; the housing 1 has an air outlet 1a and a disassembly port 1b; the fresh air housing 2 of the fresh air assembly is disposed in the housing 1 and adjacent to the disassembly port 1b, and the filter structure 3 of the fresh air assembly is detached from or extends into the fresh air duct 2a through the disassembly port 1b. It should be noted that this indoor air conditioning unit includes the fresh air assembly as described above. Since this indoor air conditioning unit adopts all the technical solutions of all embodiments of the above-described fresh air assembly, it at least has all the beneficial effects brought about by the technical solutions of the above-described embodiments, which will not be elaborated further here.

[0096] In this embodiment, since the housing 1 of the indoor unit of the air conditioner has a disassembly port 1b, and the filter structure 3 can be detached from or inserted into the fresh air flow channel 2a of the fresh air housing 2 through the disassembly port 1b, the filter structure 3 can be directly removed from the fresh air flow channel 2a through the disassembly port 1b during the disassembly and assembly process. This facilitates cleaning or replacement maintenance of the filter structure 3, and the maintained filter structure 3 can then be reinserted into the fresh air flow channel 2a through the disassembly port 1b. Thus, the disassembly and assembly of the filter structure 3 can be achieved without disassembling the panel, improving convenience and enhancing the user experience.

[0097] Furthermore, it should be noted that in embodiments where the fresh air housing 2 also has an installation port 2b, the installation port 2b is located on the side of the fresh air housing 2 facing the disassembly port 1b, so that the installation port 2b is directly opposite the disassembly port 1b, further facilitating the user to install and remove the filter structure 3 via the disassembly port 1b. Specifically, during the installation and removal of the filter structure 3, the filter structure 3 can be directly removed from the fresh air duct 2a through the disassembly port 1b and the installation port 2b, facilitating the cleaning or replacement and maintenance of the filter structure 3, and the maintained filter structure 3 can then be reintroduced into the fresh air duct 2a through the disassembly port 1b and the installation port 2b.

[0098] In one embodiment, the fresh air housing 2 and the disassembly port 1b are located at the same end in the direction of extension of the air outlet 1a.

[0099] In this embodiment, since the disassembly port 1b is located at one end of the extension direction of the air outlet 1a, the disassembly port 1b can be displayed as a false air outlet, avoiding openings in other parts of the panel and improving aesthetics. It should be noted that, in one embodiment, the disassembly port 1b is connected to the air outlet 1a, and the air can be delivered through the disassembly port 1b, increasing the air diffusion area.

[0100] In one embodiment, the indoor unit of the air conditioner also includes an air guide plate 4, which is movably installed on the housing 1 and has an extreme position that avoids the air outlet 1a; wherein, when the air guide plate 4 is in the extreme position, it avoids the disassembly port 1b and does not interfere with the travel trajectory of the filter structure 3 being disassembled and assembled in the fresh air housing 2.

[0101] In this embodiment, a guide vane 4 is also provided on the housing 1 to guide the air outlet 1a, thereby further improving the user experience. Simultaneously, when the filter structure 3 needs to be disassembled, the guide vane 4 can be moved to its limit position. At this point, the guide vane 4 avoids the disassembly port 1b, and the filter structure 3 will not interfere with the guide vane 4 during disassembly and assembly, ensuring the normal disassembly and assembly of the filter structure 3.

[0102] It should be understood that when the air conditioner vents downwards, it has the advantage of improving the efficiency of hot and cold air circulation and optimizing human comfort. It is especially suitable for air conditioning heating and energy-saving cooling scenarios in summer, which makes the downward airflow of the air guide plate 4 the most common application scenario.

[0103] Specifically, during heating, hot air is less dense than cold air and naturally tends to rise. The downward-directing airflow vane 4 directly pushes the hot air towards the ground, precisely solving the problem of hot head and cold feet in traditional heating systems. Furthermore, the hot air rises naturally from the ground, quickly filling the entire room and preventing heat from concentrating in the ceiling area and causing waste.

[0104] When cooling, downward airflow doesn't blow cold air directly at the body. Instead, it achieves indirect cooling through a well-designed angle, improving the user experience. The cold air is first directed towards the floor or walls, then reflected and diffused as a gentle airflow. This avoids direct skin contact that could cause headaches or joint discomfort, making it especially suitable for the elderly and children. The downward-directed cold air, due to its higher density, naturally diffuses towards the ground, gradually lowering the room temperature from bottom to top, resulting in a more gentle and less abrupt feeling.

[0105] Therefore, in one embodiment, when the air guide plate 4 is in the extreme position, the air guide plate 4 guides the airflow of the air outlet 1a downward or upward.

[0106] In this embodiment, since the air guide plate 4 is used in many scenarios where it blows air downwards, preferably, the extreme position of the air guide plate 4 is set to the position when blowing air downwards, so that when the user disassembles or assembles the filter structure 3, the air guide plate 4 will usually not interfere with the filter structure 3, further improving the user experience.

[0107] It should be noted that the form in which the air guide plate 4 moves relative to the housing 1 is not limited. In one embodiment, the air guide plate 4 is slidably connected to the housing 1, achieving both clearance and air guidance during the sliding process. In another embodiment, the air guide plate 4 is detachably connected to the housing 1 by bolts or clips, etc., and is movably set relative to the housing 1; when air guidance is required, the air guide plate 4 is installed on the housing 1 and positioned corresponding to the air outlet 1a; when it is necessary to avoid the disassembly port 1b and the filter structure 3, the air guide plate 4 is removed from the housing 1.

[0108] In one embodiment, the indoor unit of the air conditioner also includes a rotating arm 5, which is rotatably connected to the housing 1 and rotatably connected to the air guide plate 4. When the rotating arm 5 extends out of the air outlet 1a, the air guide plate 4 rotates to its limit position relative to the rotating arm 5.

[0109] In this embodiment, the position of the air guide plate 4 relative to the air outlet 1a is adjusted by rotating the aforementioned rotating arm 5, allowing for multi-directional stepless adjustment of the air outlet direction. Specifically, the rotating arm 5 rotates to its limit position when extending out of the air outlet 1a, ensuring that the air guide plate 4 effectively avoids the disassembly port 1b and the filter structure 3. Furthermore, in some embodiments, the rotating arm 5 is driven to rotate by a servo motor.

[0110] In one embodiment, the air guide plate 4 also has a closed position for closing the air outlet 1a, and when the air guide plate 4 is in the closed position, it blocks the disassembly port 1b.

[0111] In this embodiment, when the rotating arm 5 is rotated to the position where it is housed in the air outlet 1a, the air guide plate 4 simultaneously closes the air outlet 1a and the disassembly port 1b to prevent the disassembly port 1b from being exposed to the external environment for a long time, thereby preventing dust accumulation in the disassembly port 1b.

[0112] In one embodiment, the indoor unit of the air conditioner also includes a decorative insert, which is detachably disposed at the disassembly port 1b.

[0113] In this embodiment, when it is not necessary to disassemble the filter structure 3, the decorative insert can be installed at the disassembly port 1b of the housing 1. On the one hand, it can prevent dust accumulation at the disassembly port 1b, and on the other hand, the decorative insert can also serve a decorative purpose.

[0114] It should be noted that the embodiment of the decorative insert can be independent of the embodiment in which the air guide plate 4 blocks the disassembly port 1b when closed. That is, in another embodiment, the air guide plate 4 does not block the disassembly port 1b when closed, and in this case, the disassembly port 1b is blocked only by the decorative insert. Alternatively, the embodiment of the decorative insert can coexist with the embodiment in which the air guide plate 4 blocks the disassembly port 1b when closed; in this case, the air guide plate 4 blocks the decorative insert when closed, and the decorative insert is exposed when the air guide plate 4 is rotated to its limit position.

[0115] Furthermore, the decorative insert can be detachably connected to the housing 1 via clips, magnets, or bolts. Specifically, in this solution, the decorative insert is in the form of a decorative panel, with a filter structure 3 removal pattern and text markings on the outer side of the decorative panel, and the decorative panel is detachably connected to the housing 1 via magnetic attraction.

[0116] Furthermore, this application also provides an air conditioner, which includes an indoor unit as described above. The specific structure of the indoor unit is the same as described in the above embodiments. Since this air conditioner adopts all the technical solutions of all the embodiments of the above-described indoor unit, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated here.

[0117] In the above detailed description, reference has been made to the accompanying drawings, which illustrate specific aspects of this disclosure by way of illustration. In this regard, terms indicating direction or positional relationship, such as “center,” “longitudinal,” “lateral,” “length,” “width,” “thickness,” “upper,” “lower,” “front,” “rear,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” “outer,” “clockwise,” “counterclockwise,” “axial,” “radial,” and “circumferential,” are used with reference to the orientation of the described figures. Since components of the described device can be positioned in multiple different orientations, directional terms are used for illustrative purposes and not for limitation. It should be understood that other aspects can be utilized and structural or logical changes can be made without departing from the concept of this disclosure. Therefore, the following detailed description should not be considered limiting.

[0118] It should be understood that, unless otherwise specifically indicated, features of various embodiments of this disclosure described herein can be combined with each other. As used herein, the term “and / or” includes any one of the relevant listed items and any combination of any two or more; similarly, “at least one of…” includes any one of the relevant listed items and any combination of any two or more.

[0119] It should be understood that, unless otherwise expressly specified and limited, the terms "joining," "attaching," "installing," "connecting," "linking," "fixing," etc., used in the embodiments of this disclosure should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms herein based on the specific circumstances.

[0120] Furthermore, the term "above" as used herein with respect to components, elements, or material layers formed or located "above" a surface may be used to indicate that the component, element, or material layer is "indirectly" positioned (e.g., placed, formed, deposited, etc.) on the surface such that one or more additional components, elements, or layers are arranged between the surface and the component, element, or material layer. However, the term "above" as used with respect to components, elements, or material layers formed or located "above" a surface may also optionally have a specific meaning: that the component, element, or material layer is "directly" positioned (e.g., placed, formed, deposited, etc.) on the surface, for example, in direct contact with the surface.

[0121] Although terms such as “first,” “second,” and “third” may be used herein to describe various components, parts, regions, layers, or sections, these components, parts, regions, layers, or sections are not limited to these terms. Rather, these terms are used only to distinguish one component, part, region, layer, or section from another. Therefore, without departing from the teachings of the examples described herein, the first component, part, region, layer, or section mentioned in the examples may also be referred to as the second component, part, region, layer, or section. Furthermore, the terms “first” and “second” are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as “first” or “second” may explicitly or implicitly include at least one of that feature. In the description herein, “a plurality” means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0122] It should be understood that spatial relative terms, such as “above,” “upper,” “below,” and “lower,” are used herein to describe the relationship between one element and another shown in the figures. In addition to the orientation depicted in the figures, these spatial relative terms are also intended to encompass different orientations of the device in use or operation. For example, if the device in the figures is flipped, an element described as “above” or “upper” relative to another element would be “below” or “lower” relative to that other element. Thus, depending on the spatial orientation of the device, the term “above” encompasses both above and below orientations. Devices may have other orientations (e.g., rotated 90 degrees or in other orientations), and the spatial relative terms used herein should be interpreted accordingly.

[0123] Furthermore, the term “exemplary” is used herein to mean serving as an example, instance, or illustration. Any aspect or design described herein as “exemplary” is not necessarily to be construed as advantageous compared to other aspects or designs. Rather, the use of the term “exemplary” is intended to present the concept in a concrete manner. As used herein, the term “or” is intended to mean an inclusive “or” rather than an exclusive “or.” That is, unless otherwise specified or clear from the context, “X applies A or B” is intended to mean any of the natural inclusive arrangements. That is, “X applies A or B” satisfies any of the foregoing instances if X applies A; X applies B; or both X applies A and B. Additionally, unless otherwise specified or clear from the context to refer to the singular form, the articles “a” and “an” as used in this application and the appended claims are generally understood to mean “one or more.”

[0124] Similarly, although this disclosure has been shown and described with respect to one or more implementations, equivalent variations and modifications will occur to those skilled in the art upon reading and understanding this specification and the accompanying drawings. This disclosure includes all such modifications and variations and is limited only by the scope of the claims. In particular, with respect to the various functions performed by the components described above (e.g., elements, resources, etc.), unless otherwise indicated, the terminology used to describe such components is intended to correspond to any component (functionally equivalent) that performs the specific function of the described component, even if structurally not equivalent to the disclosed structure. Furthermore, although specific features of this disclosure may have been disclosed with respect to only one of several implementations, such features may be combined with one or more other features of other implementations, as may be desired and advantageous to any given or particular application. Moreover, with regard to the terms “comprising,” “owning,” “having,” “having,” or variations thereof as used in the detailed description or claims, such terms are intended to be inclusive in a manner similar to the term “including.”

[0125] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the utility models disclosed herein. This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of this disclosure are indicated by the following claims.

[0126] It should be understood that this disclosure is not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this disclosure is limited only by the appended claims.
