Description

Technical Field

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

[0002] With the continuous iteration and upgrading of air conditioning technology, most air conditioners have gradually evolved from simple temperature regulation devices into indoor environment regulation systems that integrate multiple functions. Some air conditioners are also equipped with fresh air function to introduce fresh outdoor air into the room, thereby improving indoor air quality.

[0003] However, in related technologies, the single direction of fresh air outlet results in poor performance in terms of fresh air feel. For example, in winter, unheated fresh air blown directly onto the human body will make users feel cold and uncomfortable; in summer, fresh air that has not been sufficiently cooled blown directly onto the human body will make users feel stuffy and hot, affecting the user's comfort. Utility Model Content

[0004] This application discloses an air conditioner that can improve the feel of fresh air and enhance human comfort.

[0005] To achieve the above objectives, this application discloses an air conditioner, comprising:

[0006] Indoor unit, the indoor unit includes:

[0007] Housing, the housing comprising:

[0008] Front panel, the front panel is provided with

[0009] The first heat exchange air outlet extends along the length of the housing and is located in the top area of ​​the front panel.

[0010] The fresh air outlet is located on one side of the first heat exchange outlet in its extension direction, and the fresh air outlet is located in the top area of ​​the front panel.

[0011] A heat exchange volute is provided, and a heat exchange air duct is formed inside the heat exchange volute. A heat exchange inlet and a heat exchange outlet are provided on the heat exchange volute. The heat exchange inlet and the heat exchange outlet are respectively located at the two ends of the heat exchange air duct. The heat exchange outlet is connected to the first heat exchange air outlet.

[0012] A fresh air volute is formed inside the volute, and a fresh air inlet and a fresh air outlet are provided on the volute. The fresh air inlet and the fresh air outlet are respectively located at both ends of the fresh air duct, and the fresh air outlet is connected to the fresh air outlet.

[0013] An air guide plate is rotatably connected to the housing. The air guide plate is configured to rotate relative to the housing to a closed position and an open position to close or open the first heat exchange air outlet and the fresh air outlet. When the air guide plate is in the open position, the air guide plate is configured to rotate relative to the housing to different angles to change the air delivery direction of the first heat exchange air outlet and the fresh air outlet.

[0014] In this way, the fresh air outlet and the first heat exchange outlet are controlled in coordination through the air guide plate, which solves the problem of poor visualization and airflow effect of the fresh air outlet at the top or front panel in traditional air conditioners. Users can more intuitively feel the fresh air being delivered, and at the same time, they can optimize the airflow by adjusting the angle of the air guide plate, making the fresh air more in line with actual usage needs.

[0015] This application also provides an air conditioner, wherein the air guide plate has an integrally connected first air guide portion and second air guide portion, the first air guide portion and the second air guide portion being arranged sequentially along the length direction of the casing; the position of the first air guide portion is opposite to the fresh air outlet and is capable of closing the fresh air outlet, and the position of the second air guide portion is opposite to the first heat exchange outlet and is capable of closing the first heat exchange outlet.

[0016] Thus, the integrated design reduces connection nodes and assembly processes, lowers the complexity and cost of manufacturing, and since the first and second air guides are integrated, they can be driven synchronously by a single drive source, which not only simplifies the drive structure but also ensures the coordination of the movements of the first and second air guides.

[0017] This application also provides an air conditioner, wherein the air guide plate includes:

[0018] The third air guide is rotatably disposed at the fresh air outlet. When the third air guide rotates relative to the housing to the closed position, the third air guide can close the fresh air outlet.

[0019] The fourth air guide is rotatably disposed at the first heat exchange outlet, and the third air guide and the fourth air guide rotate independently of each other. When the fourth air guide rotates relative to the housing to the closed position, the fourth air guide can close the first heat exchange outlet.

[0020] The indoor unit also includes:

[0021] A first driving member is connected to the third air guide section and is used to drive the third air guide section to rotate relative to the housing so that the third air guide section can switch between the closed position and the open position.

[0022] The second driving member is connected to the fourth air guide section and is used to drive the fourth air guide section to rotate relative to the housing so that the fourth air guide section can switch between the closed position and the open position.

[0023] When both the third and fourth air guides are in the open position relative to the housing, the first and second driving members can drive the third and fourth air guides to rotate to different angles, so that the fresh air outlet and the first heat exchange outlet send air into the room in different air supply directions.

[0024] Thus, the independent adjustment capabilities of the third and fourth air guide sections allow them to rotate to different angles, resulting in different air delivery directions for fresh air and heat exchange air. This prevents the fresh air and heat exchange air from mixing directly on the air guide plate, reducing the probability of condensation on the air guide plate due to excessive temperature differences.

[0025] This application also provides an air conditioner in which the hinge axis of the third air guide and the fourth air guide are on the same straight line, and there is a preset gap between the third air guide and the fourth air guide in the direction along the hinge axis.

[0026] In this way, the preset gap not only avoids direct friction between the third and fourth air guide sections when they rotate, but also provides space for their thermal expansion and contraction. For example, when the air conditioner is running, the third and fourth air guide sections may undergo slight deformation due to changes in ambient temperature. The preset gap can effectively offset the stress caused by this deformation, prevent the third and fourth air guide sections from being squeezed and deformed due to expansion, and ensure that they can maintain good sealing and rotational flexibility even after long-term use.

[0027] This application also provides an air conditioner, wherein the width of the preset gap is 2.5mm-3mm.

[0028] The lower limit of 2.5mm can cover the cumulative value of dimensional tolerances, ensuring that the third and fourth air guides do not interfere with each other when they rotate, thus ensuring smooth movement; the upper limit of 3mm can control the gap width, avoid visual abruptness, meet the requirements of refined appearance, and the gap width in this range can reduce the infiltration of external impurities and internal airflow leakage, while also reserving space for water vapor diffusion, reducing the risk of condensation.

[0029] This application also provides an air conditioner in which, when the air guide plate is in the closed position, the air guide plate can simultaneously close the first heat exchange air outlet and the fresh air outlet, and when the air guide plate is in the open position, the air guide plate can simultaneously open the first heat exchange air outlet and the fresh air outlet.

[0030] In this way, the air deflector's synchronous control of the first heat exchange air outlet and the fresh air outlet can prevent the leakage of regulated hot and cold air from the room when the air conditioner is turned off to avoid room temperature fluctuations. At the same time, it can prevent unfiltered outdoor air from flowing back in, prevent dirt and condensation from accumulating on internal components, reduce maintenance costs, and protect the indoor environment. When the air conditioner is turned on, it can allow hot and cold air to quickly regulate the room temperature and simultaneously introduce filtered fresh air, so that temperature regulation and air exchange are carried out in tandem, improving the comfort of the indoor environment.

[0031] This application also provides an air conditioner in which the width of the third air guide and the width of the fourth air guide are equal along a direction perpendicular to the hinge axis.

[0032] Thus, during assembly, since both are the same width, installation and positioning are simpler, reducing assembly errors caused by size differences and improving assembly efficiency. Furthermore, the equal width of the third and fourth air guide sections allows for a tighter fit with the edges of the fresh air outlet and the first heat exchange outlet, respectively. In the closed position, they can evenly conform to the casing structure around the outlet, reducing gaps and thus lowering the risk of external humid and hot air infiltration or internal airflow leakage.

[0033] This application also provides an air conditioner, wherein a heat exchange air inlet is provided on the housing, and the heat exchange air inlet is located on the top of the housing;

[0034] The hinge axis of the air guide plate is located above the fresh air outlet and the first heat exchange outlet.

[0035] Thus, the heat exchange air inlet is located at the top of the casing, and the air guide plate hinge shaft is above the air outlet. This allows the diffusion direction of the fresh air and heat exchange air after they are sent out from the fresh air outlet and the first heat exchange outlet to be naturally offset from the intake direction of the top air inlet, thus preventing the freshly sent airflow from being immediately drawn into the air inlet.

[0036] This application also provides an air conditioner, wherein the housing further includes:

[0037] The base plate is provided with a second heat exchange air outlet, which is connected to the heat exchange outlet.

[0038] In this way, the second heat exchange air outlet on the bottom plate and the first heat exchange air outlet on the front plate form a three-dimensional air outlet layout. Hot air has a lower density and rises easily, while cold air has a higher density and sinks easily. The air outlet on the bottom plate can directly deliver cold air to the lower part of the room (such as near the ground), reducing the loss of cold air during the rising process. When heating, the hot air blown out can diffuse upwards with the help of natural convection, complementing the air outlet on the top, accelerating the temperature balance of the whole room and avoiding the phenomenon of temperature imbalance in local areas.

[0039] This application also provides an air conditioner, wherein the base plate is further provided with a disassembly port;

[0040] The indoor unit also includes a fresh air filter, which can be inserted into the fresh air volute through the disassembly port.

[0041] In this way, the disassembly port of the base plate can be sealed with a cover or other structure when not under maintenance, preventing dust and debris from entering the unit and not affecting the normal operation of the air conditioner or the air duct sealing. When it is necessary to disassemble or install the fresh air filter, simply open the sealed structure of the base plate to directly disassemble or install the fresh air filter inserted in the fresh air volute without disassembling other core components of the air conditioner. This reduces interference with the unit structure during maintenance, lowers the risk of damage to internal components due to improper disassembly or installation, and ensures the reliability of the air conditioner.

[0069] 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, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0070] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," "horizontal," "lateral," and "longitudinal" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0071] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0072] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0073] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components whose specific types and structures may be the same or different, and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0074] As mentioned in the background section, in related technologies, the air outlet direction of fresh air is singular, resulting in poor performance in terms of the fresh air feel. For example, in winter, unheated fresh air blown directly onto the human body will make users feel cold and uncomfortable; in summer, fresh air that has not been sufficiently cooled blown directly onto the human body will make users feel stuffy and hot, affecting the user's comfort.

[0075] To address the aforementioned issues, this application provides an air conditioner in which the air guide plate can be rotated to different angles relative to the casing to flexibly change the airflow direction of the first heat exchange air outlet and the fresh air outlet. This allows the air conditioner to precisely deliver heat exchange air (cooling or heating) and fresh air to different areas of the room according to different usage scenarios and user needs. For example, in winter, warm air can be directed to the ground, and in summer, cool air can be directed to higher places, thereby significantly improving the efficiency of temperature regulation.

[0076] The following will describe specific embodiments and appendices. Figure 1-14 The technical solution of the air conditioner in this application will be further explained.

[0077] like Figure 1 and Figure 2 As shown, the air conditioner 1 may include an indoor unit 10. The indoor unit 10 is usually installed on an indoor wall or ceiling, and its core function is to exchange heat with indoor air. It absorbs indoor heat through the evaporator (when cooling) or releases heat through the condenser (when heating). At the same time, it works with a fan to send the treated air into the room to regulate the room temperature. The outdoor unit is generally installed in a ventilated outdoor location. It contains core components such as a compressor, condenser (when cooling), evaporator (when heating), and a cooling fan. It is mainly responsible for exchanging heat with outdoor air. The compressor drives the refrigerant circulation to discharge the heat transferred by the indoor unit 10 to the outside (cooling mode) or absorb heat from the outside and transfer it to the inside (heating mode).

[0078] like Figure 1 and Figure 2 As shown, the indoor unit 10 may include a housing 11.

[0079] like Figure 2 and Figure 3 As shown, the housing 11 may include a front panel 111, on which a first heat exchange air outlet 111a and a fresh air outlet 111b are provided. The front panel 111 is located on the side of the indoor unit 10 facing the user's activity area, and an operation panel may also be provided on it.

[0080] like Figure 3 As shown, the indoor unit 10 may also include a heat exchange volute 12, in which a heat exchange air duct is formed. The heat exchange volute 12 is provided with a heat exchange inlet 121 and a heat exchange outlet 122, which are located at the two ends of the heat exchange air duct, respectively. The heat exchange outlet 122 is connected to the first heat exchange air outlet 111a.

[0081] like Figure 4 and Figure 5As shown, the indoor unit 10 may also include a fresh air volute 13, in which a fresh air duct is formed. A fresh air inlet 131 and a fresh air outlet 132 are provided on the volute. The fresh air inlet 131 and the fresh air outlet 132 are located at the two ends of the fresh air duct, respectively. The fresh air outlet 132 is connected to the fresh air outlet 111b.

[0082] like Figures 6 to 8 As shown, the indoor unit 10 may also include an air guide plate 14, which is rotatably connected to the housing 11. The air guide plate 14 is configured to be able to rotate relative to the housing 11 to a closed position and an open position to close or open the first heat exchange air outlet 111a and the fresh air outlet 111b. When the air guide plate 14 is in the open position, the air guide plate 14 is configured to be able to rotate relative to the housing 11 to different angles to change the air supply direction of the first heat exchange air outlet 111a and the fresh air outlet 111b.

[0083] Thus, when the air guide plate 14 rotates relative to the casing 11 to different angles (such as 30°, 60°, 90°, etc.), the air delivery direction of the first heat exchange air outlet 111a and the fresh air outlet 111b can be flexibly changed, so that the air conditioner 1 can accurately deliver heat exchange air (cool air or warm air) and fresh air to different areas of the room according to different usage scenarios and user needs. For example, in winter, warm air can be directed to the ground, and in summer, cool air can be directed to higher places, thereby improving the efficiency of temperature regulation.

[0084] Secondly, the fresh air outlet 111b and the first heat exchange outlet 111a are controlled in coordination by the air guide plate 14, which solves the problem of poor visualization and airflow effect of the fresh air outlet 111b at the top or front of the traditional air conditioner 1. Users can more intuitively feel the fresh air being delivered. At the same time, the airflow can be optimized by adjusting the angle of the air guide plate 14, so that the fresh air is more in line with actual usage needs. For example, in winter, the fresh air can be mixed with the warm air and delivered at a suitable angle to avoid cold air blowing directly on the human body; in summer, the direction of the fresh air and cold air can be controlled to prevent stuffiness.

[0085] In some possible embodiments, such as Figure 2 As shown, the first heat exchange outlet 111a extends along the length of the housing 11, and the fresh air outlet 111b is located on one side of the first heat exchange outlet 111a in its extending direction.

[0086] The first heat exchange outlet 111a extends along the length of the casing 11 to ensure the coverage width of the heat exchange air in the room, enabling faster and more uniform adjustment of the indoor temperature. The fresh air outlet 111b is located on one side of its extension direction, which will not interfere with the large-scale diffusion of the heat exchange air, and allows the fresh air to be more naturally integrated into the indoor environment after being delivered, thanks to the flow of indoor air and the driving force of the heat exchange air, so that the distribution of fresh air is more balanced and avoids the situation of excessively high or low local fresh air concentration.

[0087] Furthermore, since the two airflows are adjacent and laterally distributed, when the air guide plate 14 is adjusted to a suitable angle, the two airflows can mix quickly and gently after being delivered, reducing the impact and turbulence between the airflows. Especially in winter, the mixing of heat exchange air (warm air) and fresh air can avoid the feeling of coldness when fresh air blows directly on the human body. In summer, the mixing of heat exchange air (cold air) and fresh air can reduce the stuffiness that fresh air may bring, further improving the user's physical comfort.

[0088] In addition to the above arrangement of placing the fresh air outlet 111b on one side of the extension direction of the first heat exchange outlet 111a, other arrangements such as vertical arrangement are possible, as those skilled in the art should know.

[0089] In some possible embodiments, such as Figure 2 As shown, both the fresh air outlet 111b and the first heat exchange outlet 111a are located in the top area of ​​the front panel 111.

[0090] Because the air outlets in the top area are positioned higher, the delivered airflow has a wider diffusion space. Therefore, after the heat exchange air is delivered from the top, it can gradually spread to the lower areas of the room by taking advantage of the natural convection characteristics of the air. Especially during summer cooling, the cold air can evenly cover the entire room from top to bottom, avoiding local areas from being too low or too high in temperature. During winter heating, although hot air itself tends to flow upward, the angle adjustment of the air guide plate 14 can guide the hot air to flow downward at an angle, reducing the phenomenon of hot air accumulating at the top and improving heating efficiency.

[0091] After the fresh air is delivered from the top, it can quickly spread to every corner along with the overall indoor air circulation, avoiding the fresh air being concentrated in a local area due to the low position of the fresh air outlet 111b, so that the air quality in all parts of the room can be effectively improved.

[0092] In some possible embodiments, such as Figure 2 As shown, the air guide plate 14 has an integrally connected first air guide section 14a and second air guide section 14b, which are arranged sequentially along the length of the casing 11. The first air guide section 14a is positioned opposite to the fresh air outlet 111b and can close the fresh air outlet 111b. The second air guide section 14b is positioned opposite to the first heat exchange outlet 111a and can close the first heat exchange outlet 111a.

[0093] Thus, the integrated design reduces connection nodes and assembly processes, lowers the complexity and cost of manufacturing, and since the first air guide 14a and the second air guide 14b are integrated, they can be rotated synchronously by a single drive source, which not only simplifies the drive structure but also ensures the coordination of the movements of the first air guide 14a and the second air guide 14b.

[0094] In some possible embodiments, such as Figure 9 and Figure 10 As shown, the air guide plate 14 may include a third air guide section 14c, which is rotatably disposed at the fresh air outlet 111b. When the third air guide section 14c rotates relative to the housing 11 to the closed position, the third air guide section 14c can close the fresh air outlet 111b.

[0095] like Figures 9 to 12 As shown, the air guide plate 14 may also include a fourth air guide section 14d, which is rotatably disposed at the first heat exchange outlet 111a. The third air guide section 14c and the fourth air guide section 14d rotate independently of each other. When the fourth air guide section 14d rotates to the closed position relative to the housing 11, the fourth air guide section 14d can close the first heat exchange outlet 111a.

[0096] like Figures 9 to 12 As shown, the indoor unit 10 may also include a first drive member 15, which is connected to the third air guide section 14c and is used to drive the third air guide section 14c to rotate relative to the housing 11 so that the third air guide section 14c can switch between a closed position and an open position.

[0097] like Figure 13 As shown, the indoor unit 10 may also include a second drive member 16, which is connected to the fourth air guide 14d and is used to drive the fourth air guide 14d to rotate relative to the housing 11 so that the fourth air guide 14d can switch between a closed position and an open position.

[0098] The first driving component 15 and the second driving component 16 can be stepper motors or servo motors, etc., which are not limited here.

[0099] When both the third air guide section 14c and the fourth air guide section 14d are in the open position relative to the housing 11, the first drive member 15 and the second drive member 16 can respectively drive the third air guide section 14c and the fourth air guide section 14d to rotate to different angles (e.g., Figure 11 and Figure 12 As shown), so that the fresh air outlet 111b and the first heat exchange outlet 111a send air into the room in different air supply directions.

[0100] Thus, the third air guide section 14c and the fourth air guide section 14d rotate independently and are controlled separately by the first drive component 15 and the second drive component 16, respectively. This allows the air delivery directions of the fresh air outlet 111b and the first heat exchange outlet 111a to be adjusted completely independently. When both are in the open position, the fresh air and heat exchange air can be adjusted to different angles according to actual needs. For example, the fresh air can be blown towards the central area of ​​the room at a gentle angle, while the heat exchange air can cover the corners of the room at a larger angle. This achieves the synergy of precise delivery of fresh air and wide diffusion of heat exchange air, meeting the user's differentiated needs for air conditions in different areas.

[0101] Furthermore, during the operation of the air conditioner 1, especially during summer cooling, the temperature of the heat exchange air is low. If it comes into direct contact with the indoor humid and hot air, and the temperature near the air outlet drops sharply, condensation is likely to occur. The independent adjustment capabilities of the third air guide section 14c and the fourth air guide section 14d allow the third air guide section 14c and the fourth air guide section 14d to rotate to different angles, so that the air supply directions of the fresh air and the heat exchange air are different. This prevents the fresh air and the heat exchange air from mixing directly on the air guide plate 14, reducing the probability of condensation on the air guide plate 14 due to excessive temperature difference.

[0102] In addition, when only the fresh air function is turned on, the third air guide 14c is open and the fourth air guide 14d is closed. At this time, the fresh air introduced can regulate the indoor humidity. When the air conditioner 1 stops running or is in a non-working state, the fourth air guide 14d can tightly seal the first heat exchange air outlet 111a and the third air guide 14c can seal the fresh air outlet 111b, reducing the amount of hot and humid air from the outside entering the air conditioner 1 and coming into contact with the low-temperature components.

[0103] In some possible embodiments, such as Figure 9 and Figure 13 As shown, the hinge axis 14e of the third air guide 14c and the fourth air guide 14d is on the same straight line, and there is a preset gap between the third air guide 14c and the fourth air guide 14d in the direction along the hinge axis 14e.

[0104] In this way, the hinge axis 14e of the third air guide 14c and the fourth air guide 14d are on the same straight line, which can ensure that when the third air guide 14c and the fourth air guide 14d rotate under the drive of the first drive member 15 and the second drive member 16 respectively, the center of the motion path coincides, thereby avoiding the intersection or overlap of motion trajectories caused by axis misalignment.

[0105] The preset gap not only avoids direct friction between the third air guide section 14c and the fourth air guide section 14d during rotation, but also provides space for thermal expansion and contraction of the third air guide section 14c and the fourth air guide section 14d. For example, when the air conditioner 1 is running, the third air guide section 14c and the fourth air guide section 14d may undergo slight deformation due to changes in ambient temperature (such as contact with cold air when cooling in summer and proximity to hot air flow when heating in winter). The preset gap can effectively offset the stress caused by such deformation, prevent the third air guide section 14c and the fourth air guide section 14d from being squeezed and deformed due to expansion, and ensure that they can maintain good sealing and rotational flexibility even after long-term use.

[0106] In some possible embodiments, the width of the preset gap is 2.5mm-3mm.

[0107] Setting the width of the preset gap within the range of 2.5mm-3mm is the optimal choice after comprehensively considering dimensional tolerances, appearance requirements, and functional stability. Deviating from this range will bring obvious drawbacks.

[0108] If the width of the preset gap is greater than 3mm, the excessive gap will disrupt the visual break between the third air guide 14c and the fourth air guide 14d in the closed position, resulting in a decrease in aesthetic appearance.

[0109] If the width of the preset gap is less than 2.5mm, the gap is too small and cannot offset the dimensional fluctuations caused by production or assembly errors. This may cause the third air guide 14c and the fourth air guide 14d to rub against each other and get stuck when rotating. In severe cases, it may even damage the drive components or the structure of the air guide. In addition, the gap is too small and will compress the ventilation space. When the air conditioner is running, the water vapor condensed on the surface of the third air guide 14c and the fourth air guide 14d is difficult to diffuse and is easy to accumulate in the gap, increasing the risk of condensation dripping or seeping into the equipment, affecting the user experience and equipment life.

[0110] Based on this, this embodiment controls the width of the preset gap between 2.5mm and 3mm. This not only covers the cumulative value of dimensional tolerances, ensuring that the air guides do not interfere with each other when rotating and guaranteeing smooth movement, but also controls the gap width to avoid visual abruptness, reduce the infiltration of external impurities and leakage of internal airflow, reserve space for water vapor diffusion, and reduce the risk of condensation.

[0111] In some possible embodiments, when the air guide plate 14 is in the closed position, the air guide plate 14 can simultaneously close the first heat exchange air outlet 111a and the fresh air outlet 111b, and when the air guide plate 14 is in the open position, the air guide plate 14 can simultaneously open the first heat exchange air outlet 111a and the fresh air outlet 111b.

[0112] When the air conditioner 1 is turned off, the air guide plate 14 can simultaneously close the first heat exchange air outlet 111a and the fresh air outlet 111b. In this way, the closure of the first heat exchange air outlet 111a can prevent the regulated hot or cold air in the room from leaking out through the first heat exchange air outlet 111a, thus avoiding indoor temperature fluctuations. The closure of the fresh air outlet 111b can effectively prevent unfiltered outdoor air from flowing back into the unit, preventing dust, moisture and other impurities from adhering to the internal components, reducing the risk of equipment dirt accumulation and condensation, reducing maintenance costs, and at the same time preventing poor outdoor air from affecting the indoor environment.

[0113] When the air conditioner 1 is turned on, the air guide plate 14 can simultaneously open the first heat exchange air outlet 111a and the fresh air outlet 111b. In this way, the hot and cold air delivered by the first heat exchange air outlet 111a can quickly enter the room, adjust the room temperature in time, and meet the user's temperature needs. The fresh air outlet 111b simultaneously introduces filtered fresh air, improves the indoor air quality, and allows the cooling and heating regulation and air exchange to work together to improve the comfort of the indoor environment.

[0114] In some possible embodiments, such as Figure 10 As shown, the widths of the third air guide 14c and the fourth air guide 14d are equal along the direction perpendicular to the hinge axis 14e.

[0115] Thus, during assembly, since both have the same width, installation and positioning are simpler, reducing assembly errors caused by size differences and improving assembly efficiency. Furthermore, the equal width of the third air guide 14c and the fourth air guide 14d allows for a tighter fit with the edges of the fresh air outlet 111b and the first heat exchange outlet 111a, respectively. In the closed position, they can evenly fit the casing 11 structure around the outlet, reducing gaps and thus lowering the risk of external humid and hot air seeping in or internal airflow leakage.

[0116] Furthermore, when both are in the closed position, the edges of equal width can form a smooth connection with the surface of the casing 11, avoiding visual abruptness caused by size differences, and making the front panel 111 of the indoor unit 10 present a simple and unified overall feel; while in the open state, there will be no unbalanced visual experience with one side of the air guide being too wide and the other side being too narrow, ensuring the aesthetics of the air conditioner 1.

[0117] In some possible embodiments, such as Figure 7 As shown, a heat exchange air inlet 11a is also provided on the housing 11, and the heat exchange air inlet 11a is located on the top of the housing 11.

[0118] like Figure 7 As shown, the hinge shaft 14e of the air guide plate 14 is located above the fresh air outlet 111b and the first heat exchange outlet 111a.

[0119] Thus, the heat exchange air inlet 11a is located at the top of the casing 11, and the air guide plate 14 hinge shaft 14e is above the air outlet. This allows the fresh air and heat exchange air to be sent out from the fresh air outlet 111b and the first heat exchange air outlet 111a, and their diffusion direction is naturally offset from the suction direction of the top air inlet, thus preventing the freshly sent airflow from being immediately sucked into the heat exchange air inlet 11a.

[0120] In some possible embodiments, such as Figure 14 As shown, the housing 11 may also include a base plate 112, on which a second heat exchange outlet 112a is provided, and the second heat exchange outlet 112a is connected to the heat exchange outlet 122.

[0121] In this way, the second heat exchange air outlet 112a on the base plate 112 and the first heat exchange air outlet 111a on the front plate 111 form a three-dimensional air outlet layout. Hot air has a low density and rises easily, while cold air has a high density and sinks easily. The air outlet on the base plate 112 can directly deliver cold air to the lower part of the room (such as near the ground), reducing the loss of cold air during the rising process. When heating, the hot air can diffuse upwards with the help of natural convection, complementing the air outlet at the top, accelerating the temperature balance of the whole room, and avoiding the occurrence of temperature imbalance in local areas.

[0122] Furthermore, different air outlets can be selected in different adjustment modes to improve heat exchange efficiency. For example, in cooling mode, the second heat exchange outlet 112a is selected first. Because cold air is denser, it will naturally sink. The cold air delivered from the bottom outlet can directly diffuse to the ground and the lower part of the room, and then gradually spread upwards, avoiding the situation where cold air concentrates at the top while the ground remains stuffy. In heating mode, the first heat exchange outlet 111a is selected first. Because hot air is less dense, it will naturally rise. The hot air delivered from the upper middle outlet can first diffuse to the upper part of the room, and then slowly flow downwards through natural convection, effectively avoiding the problem of hot air accumulating at the top while the ground remains cold. This air delivery method allows hot air to cover a wider area, reducing the temperature difference between the ground and the top, thereby improving the applicability of air conditioner 1.

[0123] In some possible embodiments, such as Figure 14 As shown, the base plate 112 may also be provided with a disassembly port 112b.

[0124] like Figure 4 As shown, the indoor unit 10 also includes a fresh air filter 17, which can be inserted into the fresh air volute 13 via the disassembly port 112b. The main function of the fresh air filter 17 is to filter dust, particulate matter, pollen, hair and other impurities in the outdoor fresh air. It can be a pre-filter, activated carbon filter, HEPA filter, composite filter, etc.

[0125] In this way, the disassembly port 112b of the base plate 112 can be sealed by a cover or other structure when not under maintenance, preventing dust and debris from entering the body and not affecting the normal operation of the air conditioner 1 and the air duct sealing. When it is necessary to disassemble or install the fresh air filter 17, simply open the closed structure of the base plate 112 to directly disassemble or install the fresh air filter 17 inserted in the fresh air volute 13 without disassembling other core components of the air conditioner 1. This reduces interference with the body structure during maintenance, lowers the risk of damage to internal components due to improper disassembly or installation, and ensures the operational reliability of the air conditioner 1.

[0126] Furthermore, the base plate 112 area is relatively open, and placing the disassembly port 112b here will not occupy key areas related to air outlet and air inlet functions, such as the front plate 111 and the top, thus avoiding any impact on the appearance integrity of the air conditioner 1 and the layout of its main functional components.

[0127] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the air conditioner of this application, and are not intended to limit it. Although the air conditioner of this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
