Description

Technical Field

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

[0002] An air conditioner, also known as an air conditioner, is a device that uses artificial means to regulate and control parameters such as temperature, humidity, and airflow of the air inside a building or structure.

[0003] Currently, people typically install air conditioners on the ceiling of a room to regulate the temperature of the indoor air.

[0004] In the existing technology, the air outlet grille of the air conditioner panel is a regular grille. Regular grilles cannot adjust the direction of the airflow and can only adjust the airflow direction through the air guide plate. Since regular air outlet grilles cannot adjust the airflow direction, a large temperature difference occurs between the air at the top of the room and the air blown out by the air outlet grille, causing condensation to occur on the upper edge of the panel near the air outlet, which will affect the user's safety when using the air conditioner. Utility Model Content

[0005] This application discloses an air conditioner that can blow air upwards through the air outlet grille on the panel, avoiding a large temperature difference between the air at the top of the room and the air blown out by the air outlet grille, thereby preventing condensation problems on the upper side of the panel near the air outlet and ensuring user safety.

[0006] To achieve the above objectives, some embodiments of this application provide an air conditioner, including:

[0007] Indoor unit, the indoor unit includes:

[0008] A housing for fixing to the ceiling of an interior space, the housing comprising:

[0009] The front panel of the housing is provided with an air outlet.

[0010] A panel, located outside the housing and opposite to the front panel of the housing, the panel having an air outlet that communicates with the air outlet of the housing, the panel comprising:

[0011] An air outlet grille, disposed at the air outlet of the panel, is used to adjust the airflow direction of the air outlet of the panel. The air outlet grille includes:

[0012] Multiple first grille blades, with the outlet side of the multiple first grille blades tilted upwards to guide the airflow upwards.

[0013] In this way, the air outlet grille of the indoor unit's panel is tilted upwards on the air outlet side. This allows the airflow to be guided upwards by the upward-tilted grille blades. When the air conditioner is in cooling mode, the upward airflow, guided by the grille blades, delivers cool air to the top of the room, promoting air circulation and exchange. This helps reduce uneven temperature distribution and lowers the temperature of the air at the top of the room. This prevents a large temperature difference between the edge of the air outlet and the air temperature at the top of the room when cold air is output from the panel. This avoids condensation on the panel caused by a large temperature difference between the edge of the air outlet and the air temperature at the top of the room. A large temperature difference between the edge of the air outlet and the air temperature at the top of the room means that the surface temperature of the panel around the air outlet is lower than the dew point temperature of the air at the top of the room. When the water vapor content in the air is high and the air temperature drops to a certain level, the water vapor will condense into water droplets on the panel around the air outlet, forming condensation. When the air outlet side of the first grille blade is tilted upwards, the cold air is directed towards the top of the room. This lowers the temperature of the air at the top of the room, reducing the temperature difference between the air at the top of the room and the surface of the panel. This lowers the dew point temperature of the air at the top of the room, ensuring that the temperature of the panel around the air outlet does not fall below the dew point temperature of the air at the top of the room. This avoids condensation problems, extends the lifespan of the internal components of the air conditioner indoor unit, and also ensures the safety of users when using the air conditioner.

[0014] In some embodiments of this application, a plurality of the first grid leaves are spaced apart along the vertical direction.

[0015] In this way, the multiple first grille blades spaced vertically together form multiple air channels. These channels facilitate smoother airflow, reduce resistance and turbulence during airflow, enhance airflow efficiency, and thus improve the air conditioning's delivery efficiency. Simultaneously, the spaced vertical arrangement of the multiple first grille blades also forms a supporting structure, enhancing the overall stability of the panel and helping to reduce deformation or damage during long-term use, thereby extending the air conditioner's lifespan.

[0016] In some embodiments of this application, the spacing between any two adjacent first grid leaves is equal.

[0017] Thus, setting the first grille blades at equal intervals ensures that the airflow through each blade is approximately the same, resulting in more uniform air distribution. This helps prevent some areas from being over-cooled or over-heated while others remain under-cooled, improving indoor comfort. Simultaneously, the equally spaced first grille blades help reduce eddies and turbulence generated during airflow, thereby lowering the noise level of the panel's air outlet. Furthermore, during air conditioning operation, the equally spaced first grille blades better guide airflow, ensuring sufficient heat dissipation from the heat exchanger, which helps improve the air conditioner's operating efficiency, extend its lifespan, and reduce energy consumption.

[0018] In some embodiments of this application, a plurality of the first grid blades are parallel to each other.

[0019] In this way, the parallel arrangement of multiple first grille blades ensures that air encounters uniform and consistent resistance as it passes through, thereby reducing the generation of eddies and turbulence. This contributes to smoother and more efficient airflow, improving the air conditioning's delivery efficiency and comfort. Furthermore, because the first grille blades are parallel, they can evenly distribute airflow, ensuring that each blade delivers the same amount of air. This further prevents some areas from being over-cooled or over-heated while others remain under-cooled, resulting in a more uniform indoor temperature and air distribution. In addition, the neat arrangement of the parallel grille blades creates a clean and modern aesthetic, a design that not only aligns with contemporary home aesthetic trends but also enhances the overall quality of the air conditioning system.

[0020] In some embodiments of this application, the air outlet grille further includes:

[0021] Multiple second grille blades are located below multiple first grille blades, and the multiple second grille blades are used to guide the airflow to be horizontal or downward.

[0022] Thus, the second grille blade below the first grille blade enables the air outlet grille to achieve upward airflow while also accommodating horizontal or downward airflow, enhancing the flexibility of the air outlet grille on the panel. At the same time, the second grille blade can guide the air to flow horizontally or downward, which helps to achieve a more uniform indoor temperature distribution and thus improve the comfort of the indoor environment.

[0023] In some embodiments of this application, a plurality of second grid leaves are spaced apart along the vertical direction.

[0024] In this way, the vertically spaced second grille blades can form multiple air channels, which helps air pass through more smoothly, reduces flow resistance, accelerates air circulation in the room, improves air supply efficiency, and allows the indoor temperature to reach the set value more quickly. Furthermore, the vertically spaced second grille blades can more effectively guide airflow, reduce unnecessary energy consumption, help improve the energy efficiency ratio of the air conditioner, lower operating costs, and align with the environmental protection concept of energy conservation and emission reduction.

[0025] In some embodiments of this application, the spacing between any two adjacent second grid leaves is equal.

[0026] In this way, by using multiple equally spaced second grille blades, air distribution can be optimized, so that air can be evenly distributed in all corners of the room. At the same time, each second grille blade can play the same air supply role, thereby ensuring that the air supply effect of the entire air outlet grille is consistent and improving the comfort of the indoor environment.

[0027] In some embodiments of this application, a plurality of the second grid blades are parallel to each other.

[0028] Thus, the parallel second grille blades ensure that the air experiences uniform and stable resistance as it passes through, reducing the generation of eddies and turbulence. This contributes to a smoother and more continuous airflow, improving air delivery efficiency while reducing noise levels. Because the second grille blades are parallel, they can more effectively guide the airflow in a predetermined direction, helping to ensure consistent airflow direction across the entire outlet grille and avoiding problems such as uneven airflow or directional deviation.

[0029] This application also provides an air conditioner, including:

[0030] Indoor unit, the indoor unit includes:

[0031] A housing for fixing to the ceiling of an interior space, the housing comprising:

[0032] The front panel of the housing is provided with an air outlet.

[0033] A panel is located outside the housing and is opposite to the front panel of the housing. The panel has a panel air outlet, which is connected to the air outlet of the housing.

[0034] The first air guide plate assembly includes:

[0035] The first air guide plate is rotatably connected to the air outlet of the panel. The rotation axis of the first air guide plate extends along the horizontal direction. The first air guide plate rotates to adjust the vertical air outlet direction. When the air conditioner is in cooling mode, the first air guide plate can rotate between a first state and a second state. When the first air guide plate is in the first state, the air outlet side of the first air guide plate is tilted upward to guide the airflow upward. When the first air guide plate is in the second state, the air outlet side of the first air guide plate extends horizontally or tilts downward to guide the airflow horizontally or downward.

[0036] Thus, the indoor unit's casing is fixed to the ceiling, allowing it to be suspended from the ceiling. The front panel of the casing has an air outlet, and the indoor unit's control panel is located outside the casing, opposite the front panel. The control panel has an air outlet, allowing cool or hot air from the air conditioner to be blown out through the casing outlet and then into the room through the control panel outlet. A first air guide plate is rotatably connected to the control panel outlet, and its axis of rotation extends horizontally, allowing users to easily adjust the vertical airflow direction by rotating the first air guide plate. When the air conditioner is in cooling mode, the first air guide plate can rotate freely between a first state and a second state, guiding the airflow upwards, horizontally, or downwards, respectively, meeting different airflow adjustment requirements. When the first air guide plate is in the first state, its outlet side is tilted upwards, effectively delivering cool air to higher positions in the room, achieving a more uniform indoor temperature distribution and avoiding condensation problems caused by excessive temperature differences between the ceiling and the control panel outlet. When the first air guide plate is in the second state, its air outlet side extends horizontally or tilts downward, which can guide the air to flow to all corners of the room, reduce temperature differences and dead zones, and make the room reach the preset temperature more quickly.

[0037] In some embodiments of this application, the first air guide plate also includes a closed state. When the first air guide plate is in the closed state, the first air guide plate is parallel to the vertical direction, and the rotation axis of the first air guide plate is located above the air outlet of the panel. The surface of the first air guide plate facing the air outlet of the housing is the inner surface. When the first air guide plate is in the first state, the angle between the inner surface of the first air guide plate and the vertical direction is 98 to 102 degrees.

[0038] Thus, the angle between the first air guide plate and the vertical direction of 98 to 102 degrees helps optimize indoor air circulation. When the first air guide plate is tilted upward at any angle between 98 and 102 degrees, it can guide the air to a higher position in the room, thereby promoting air circulation throughout the room and helping to achieve a more uniform indoor temperature distribution. At the same time, when the first air guide plate is tilted upward at any angle between 98 and 102 degrees, the upward-tilted air can reduce the discomfort caused by direct airflow.

[0039] In some embodiments of this application, the first air guide plate also includes a closed state. When the first air guide plate is in the closed state, the first air guide plate is parallel to the vertical direction, and the rotation axis of the first air guide plate is located above the air outlet of the panel. The surface of the first air guide plate facing the air outlet of the housing is the inner surface. When the first air guide plate is in the second state, the angle between the inner surface of the first air guide plate and the vertical direction is 43 to 47 degrees.

[0040] Thus, when the first air guide plate is tilted at any angle between 43 and 47 degrees, the air conditioner is in cooling mode and the air volume is relatively small. It can more effectively guide the cold air to all corners of the room, which helps to reduce temperature differences and dead corners, so that the indoor temperature drops evenly. It can prevent the large volume of cold air from blowing directly on people, and can improve the user's comfort while meeting the user's temperature requirements.

[0041] This application also provides an air conditioner, including:

[0042] Indoor unit, the indoor unit includes:

[0043] A housing for fixing to the ceiling of an interior space, the housing comprising:

[0044] The front panel of the housing is provided with an air outlet.

[0045] A panel is located outside the housing and is opposite to the front panel of the housing. The panel has a panel air outlet, which is connected to the air outlet of the housing.

[0046] The first air guide plate assembly includes:

[0047] The first air guide plate is rotatably connected to the air outlet of the panel. The rotation axis of the first air guide plate extends along the horizontal direction. The first air guide plate rotates to adjust the vertical air outlet direction. When the air conditioner is in heating mode, the first air guide plate can rotate between a first state and a second state. When the first air guide plate is in the first state or the second state, the air outlet side of the first air guide plate is tilted downward.

[0048] In this way, when the air conditioner is in heating mode, the air outlet side of the first air guide plate is tilted downwards, which can more effectively guide the hot air to the lower position of the room. This avoids the hot air blowing directly onto the ceiling or upper space, reduces the accumulation and waste of heat at the top of the room, makes the indoor temperature more uniform, improves the heating effect of the air conditioner, and provides users with a more comfortable and warm indoor environment.

[0049] In some embodiments of this application, the first air guide plate further includes a closed state. When the first air guide plate is in the closed state, the first air guide plate is parallel to the vertical direction, and the rotation axis of the first air guide plate is located above the air outlet of the panel. The surface of the first air guide plate facing the air outlet of the housing is the inner surface. When the first air guide plate is in the first state, the angle between the inner surface of the first air guide plate and the vertical direction is 23 to 27 degrees.

[0050] Thus, in heating mode, the angle of 23 to 27 degrees ensures that the hot air can be evenly distributed in the lower part of the room. At this time, the air volume of the hot air is small. The angle between the first air guide plate and the vertical direction is any angle of 23 to 27 degrees to maintain the uniform delivery of hot air into the room, avoiding the dryness and discomfort caused by the hot air blowing directly on the human body, and improving the thermal comfort of users using air conditioning.

[0051] In some embodiments of this application, the first air guide plate also includes a closed state. When the first air guide plate is in the closed state, the first air guide plate is parallel to the vertical direction, and the rotation axis of the first air guide plate is located above the air outlet of the panel. The surface of the first air guide plate facing the air outlet of the housing is the inner surface. When the first air guide plate is in the second state, the angle between the inner surface of the first air guide plate and the vertical direction is 63 to 67 degrees.

[0052] Thus, the angle between the first air guide plate and the vertical direction is 63-67 degrees, allowing the first air guide plate to deliver air to a wider space. Especially in higher indoor environments, this design ensures that hot air covers every corner of the room, improving the uniformity of indoor temperature. When the first air guide plate is tilted at any angle between 63 and 67 degrees, it can more effectively guide airflow, forming stronger air convection. This helps to accelerate the change in indoor temperature, allowing the air conditioner to reach the desired indoor temperature in a shorter time. This not only helps save energy but also significantly improves the heating efficiency of the air conditioner. The 63-67 degree angle design prevents hot air from blowing directly onto people, causing discomfort, and also prevents the hot air from deviating too far from the target area, achieving a better air delivery effect.

[0053] In some embodiments of this application, the indoor unit further includes:

[0054] The second air guide plate is disposed at the air outlet of the panel. The second air guide plate can rotate in the horizontal direction to adjust the horizontal air outlet direction.

[0055] In this way, the second air guide plate can rotate freely in the horizontal direction, allowing users to precisely adjust the air supply direction as needed. This ensures that the air conditioning air can evenly cover the entire room, avoiding situations where certain areas are too cold or too hot in the horizontal direction, thus improving the comfort and efficiency of the air conditioning and optimizing the airflow distribution in the room.

[0056] In some embodiments of this application, the indoor unit further includes:

[0057] The third air guide plate is attached to the lower side of the panel. The third air guide plate can switch between an open state and a closed state. When the third air guide plate is in the closed state, it blocks the air outlet of the panel. When the third air guide plate is opened to the maximum state, it is located below the housing.

[0058] Thus, when the second air guide plate is closed, the third air guide plate blocks the air outlet of the panel, allowing the panel to blend seamlessly with the decoration on both sides of the interior ceiling, making the air conditioner's appearance more aesthetically pleasing. When the third air guide plate is open, it can change the vertical airflow direction. When the third air guide plate is fully open, it will be located below the casing, enabling a wider airflow angle and allowing the airflow to cover a larger indoor area.

[0059] In some embodiments of this application, the indoor unit further includes:

[0060] A drive assembly is disposed on the panel and is configured to drive the first air guide plate, the second air guide plate, and the third air guide plate to rotate.

[0061] In this way, by simultaneously controlling the rotation of the first, second, and third air guide vanes through the drive components, a more complex and precise air delivery mode can be achieved. This allows the air conditioner to adjust the angle of each air guide vane according to the user's actual needs, thereby achieving all-round air delivery coverage. Furthermore, the precise control of the drive components allows the air guide vanes to remain at any desired angle, ensuring the accuracy of the air delivery direction and helping to meet the user's personalized needs for indoor temperature distribution.

[0062] Compared with the prior art, the beneficial effects of this application are at least as follows:

[0063] This application provides an air conditioner whose indoor unit includes a casing and a panel. The casing is used to fix the indoor unit to the ceiling of the room. The casing includes a front panel with an air outlet. The panel is located outside the casing and opposite to the front panel. The panel has an air outlet that communicates with the casing air outlet. The panel includes an air outlet grille located at the air outlet and used to adjust the airflow direction. The air outlet grille includes multiple first grille blades, with the air outlet side of the multiple first grille blades tilted upwards to guide the airflow upwards. In this way, when air is discharged from the panel air outlet, the airflow can be directed upwards through the first grille blades, allowing the air to evenly cover the ceiling of the room. This prevents condensation from forming on the edge of the panel near the air outlet due to a large temperature difference between the ceiling and the air discharged from the panel air outlet, ensuring user safety when using the air conditioner.

[0087] 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.

[0088] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "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.

[0089] 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.

[0090] 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.

[0091] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), 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.

[0092] Air conditioning, also known as an air conditioner, is a device that uses artificial means to regulate and control parameters such as temperature, humidity, and airflow within a building or structure. It effectively regulates indoor air temperature, humidity, and airflow, bringing great convenience to people's lives.

[0093] Nowadays, as people have higher requirements for indoor temperature, they tend to choose to install air conditioners indoors to regulate the temperature, and usually install the air conditioners on the ceiling.

[0094] Currently, most air conditioning units on the market use ordinary air outlet grilles on the panel. These grilles lack airflow direction adjustment capabilities, relying primarily on air guide vanes installed inside the outlets to adjust airflow direction. However, the adjustment range of these vanes is limited and their effectiveness is less than ideal, resulting in airflow not being evenly distributed throughout the room. Because ordinary air outlet grilles cannot directly influence airflow direction, a significant temperature difference exists between the air at the top of the room and near the grille (especially near the edge of the outlet) and the air directly blown out by the airflow. Air has a dew point temperature; when the temperature is below this point, water vapor in the air condenses into water droplets, causing condensation. This temperature difference, where the temperature around the outlet is lower than the dew point temperature of the air at the top of the room, leads to condensation on the upper side of the air conditioning panel near the outlet. This not only affects aesthetics but may also pose a potential safety threat to users.

[0095] To address the aforementioned technical issues, this application provides an air conditioner with an air outlet grille that enables different airflow directions, which can more effectively regulate and guide airflow, reduce the temperature difference between the airflow and indoor air, thereby preventing or reducing condensation and improving the efficiency, comfort, and safety performance of the air conditioning system.

[0096] The present technical solution will be further described below with reference to the embodiments and accompanying drawings.

[0097] Please see Figures 1 to 3 One embodiment of this application provides an air conditioner 100, which includes an indoor unit 101. The indoor unit 101 is an important component of the air conditioner 100, and it performs a refrigeration cycle using a compressor, condenser, expansion valve, etc. The refrigeration cycle includes a series of processes involving compression, condensation, throttling, and evaporation, supplying cooling or heating energy to the regulated and heat-exchanged air. The compressor compresses the refrigerant gas at a low temperature and low pressure, discharging it at a high temperature and high pressure. The discharged refrigerant gas flows into the condenser, where it condenses the compressed refrigerant into a liquid phase, releasing heat to the surrounding environment through the condensation process. The expansion valve throttles the high-temperature, high-pressure liquid refrigerant condensed in the condenser into a low-pressure gas-liquid two-phase refrigerant. After absorbing heat and evaporating in the expansion valve, the refrigerant is in a low-temperature, low-pressure state. The refrigerant gas then returns to the compressor, where it exchanges heat with the material to be cooled using the latent heat of vaporization of the refrigerant, achieving a cooling effect. This allows the indoor unit 101 to regulate the temperature of the indoor space.

[0098] The indoor unit 101 includes a housing 1, which is used to fix the indoor unit 101 to the top of the room.

[0099] The housing 1 includes a front panel 11, on which an air outlet 1a is provided. When the fan of the indoor unit 101 rotates, it delivers cold or hot air to the room through the air outlet 1a.

[0100] The indoor unit 101 also includes a panel 2, which is located outside the housing 1 and is positioned opposite to the front panel 11 of the housing. The panel 2 is used to integrate functional modules such as display module and language module, and also serves as a decorative element.

[0101] The panel 2 is provided with a panel air outlet 2a, which is connected to the housing air outlet 1a and is used to guide the gas of the indoor unit 101 into the room from the panel air outlet 2a.

[0102] like Figures 4 to 6 As shown, panel 2 includes an air outlet grille 21, which is located at the air outlet 2a of the panel and is used to adjust the airflow direction of the air outlet 2a of the panel.

[0103] Combination Figure 6 and Figure 8 The air outlet grille 21 includes a plurality of first grille blades 211, the air outlet side of the plurality of first grille blades 211 being inclined upward to guide the airflow upward.

[0104] The multiple first grid leaves 211 refer to at least two first grid leaves 211, that is, the first grid leaves 211 can be two, three, five or more, and this embodiment does not make a specific limitation on this.

[0105] In this way, by setting the air outlet side of the multiple first grille blades 211 of the air outlet grille 21 to be tilted upward, when the indoor unit 101 is operating, the airflow can be guided upward by the first grille blades 211, that is, directed towards the top of the room. If the air conditioner is in cooling mode, a large amount of hot air will accumulate at the top of the room. By guiding the first grille blades 211, cold air is delivered to the top of the room, promoting the circulation and exchange of air at the top of the room. This can reduce uneven indoor temperature distribution. Outputting cold air to the top of the room lowers the air temperature at the top of the room, which can prevent cold air from being output from the panel air outlet 2a of the panel 2, because the edge of the panel air outlet 2a... The temperature difference between the air at the top of the room and the air temperature at the bottom of the panel is too large. The temperature at the edge of the air outlet 2a is lower than the dew point temperature of the air at the top of the room, causing condensation on the panel 2. If condensation occurs on the panel 2, water droplets may drip onto other electrical appliances or the interior of the indoor unit 101. Therefore, the upward tilt of the first grille blade 211 directs cool air towards the top of the room, lowering the temperature of the air at the top and reducing the temperature difference between the air at the top and the panel surface. This lowers the dew point temperature of the air at the top, preventing the temperature of the panel around the air outlet from falling below the dew point temperature of the air at the top. Preventing condensation on the panel 2 ensures the lifespan of the internal components of the air conditioner indoor unit and guarantees user safety when using the air conditioner.

[0106] Furthermore, such as Figures 6 to 8 As shown, multiple first grid leaves 211 are arranged at intervals along the vertical direction. That is to say, there is a gap between every two adjacent first grid leaves 211.

[0107] In this way, the multiple first grille blades 211 are arranged at intervals along the vertical direction, forming multiple air channels. These multiple air channels facilitate smoother airflow, reduce air resistance and turbulence during airflow, enhance airflow efficiency, and thus improve the air delivery efficiency of the indoor unit 101 of the air conditioner 100. Simultaneously, the multiple first grille blades 211 arranged at intervals along the vertical direction form a certain support structure at the panel air outlet 2a, enhancing the overall stability of the panel 2 to some extent and helping to reduce deformation and damage to the panel 2 during long-term use.

[0108] Furthermore, the spacing between any two adjacent first grid leaves 211 is equal. That is to say, the multiple first grid leaves 211 are arranged at equal intervals.

[0109] In this way, setting the first grille blades 211 at equal intervals ensures that the airflow through each first grille blade 211 is approximately the same, thereby enabling the indoor unit 101 to achieve a more uniform airflow effect. This helps avoid the problem of some areas being over-cooled or over-heated while other areas are under-cooled, improving the comfort of the indoor environment. Simultaneously, the design of the equal-interval first grille blades 211 helps reduce eddies and turbulence generated during airflow, thus lowering the noise level of the panel air outlet 2a. Furthermore, during the operation of the air conditioner 100, the equal-interval first grille blades 211 can better guide airflow, ensuring sufficient heat dissipation from the heat exchanger, which helps improve the operating efficiency of the air conditioner 100, extend its service life, and reduce energy consumption.

[0110] Optionally, multiple first grille blades 211 are parallel to each other. This parallel arrangement ensures that air experiences uniform and consistent resistance as it passes through, reducing the generation of eddies and turbulence. This contributes to smoother and more efficient airflow, improving the air delivery efficiency and comfort of the air conditioner 100. Furthermore, because the first grille blades 211 are parallel, they can evenly distribute airflow, ensuring that each blade performs the same air delivery function. This further prevents some areas from being over-cooled or over-heated while others remain under-cooled, achieving a more uniform indoor temperature and air distribution. In addition, the neat arrangement of the parallel first grille blades 211 creates a simple and modern aesthetic, which not only aligns with modern home design trends but also enhances the overall quality of the air conditioner 100.

[0111] In some embodiments, as Figure 6 and Figure 8 As shown, the air outlet grille 21 of panel 2 also includes a plurality of second grille blades 212, which are located below a plurality of first grille blades 211. The plurality of second grille blades 212 are used to guide the airflow to be horizontal or downward. That is to say, a plurality of second grille blades 212 for guiding horizontal or downward airflow are provided below the first grille blades 211.

[0112] The multiple second grid leaves 212 refer to at least two second grid leaves 212, that is, there can be two, three, five or more second grid leaves 212. This embodiment does not make a specific limitation on this.

[0113] It should be noted that both upward and downward airflow are based on the horizontal direction. That is to say, upward deflection in the horizontal direction is upward airflow, and downward deflection in the horizontal direction is downward airflow.

[0114] In this way, the second grille blade 212 below the first grille blade 211 enables the air outlet grille 21 to achieve upward airflow while also accommodating horizontal or downward airflow, enhancing the flexibility of the air outlet grille 21 of the panel air outlet 2a. At the same time, the second grille blade 212 can guide the air to flow horizontally or downward, which helps to achieve a more uniform indoor temperature distribution and thus improve the comfort of the indoor environment.

[0115] Furthermore, if Figure 6 and Figure 8 As shown, multiple second grid leaves 212 are arranged at intervals along the vertical direction. That is to say, there is a gap between each two adjacent second grid leaves 212.

[0116] Similar to the above embodiments where multiple first grille blades 211 are spaced apart vertically, vertically spaced second grille blades 212 can form multiple air channels, facilitating smoother airflow, reducing flow resistance, accelerating air circulation within the room, improving air delivery efficiency, and allowing the indoor temperature to reach the set value more quickly. Furthermore, the vertically spaced second grille blades 212 can more effectively guide airflow, reducing unnecessary energy consumption, helping to improve the energy efficiency ratio of the air conditioner 100, reducing operating costs, and conforming to the environmental protection concept of energy conservation and emission reduction.

[0117] Furthermore, the spacing between any two adjacent second grid leaves 212 is equal. That is to say, the multiple second grid leaves 212 are arranged at equal intervals along the vertical direction.

[0118] In this way, by using multiple equally spaced second grille blades 212, the air distribution at the panel air outlet 2a can be optimized, so that the air blown out from the panel air outlet 2a can be evenly distributed in all corners of the room. At the same time, each second grille blade 212 can play the same air supply role, thereby ensuring that the air supply effect of the entire air outlet grille 21 is consistent, preventing the indoor temperature from not being able to be adjusted to the preset temperature in time due to differences in the air supply effect of the air outlet grille 21, and improving the comfort of the indoor environment.

[0119] Optionally, multiple second grille blades 212 are parallel to each other. This parallel arrangement ensures that air experiences uniform and stable resistance as it passes through, reducing the generation of eddies and turbulence, contributing to smoother and more continuous airflow, improving the air delivery efficiency of the indoor unit 101, and reducing noise levels at the panel air outlet 2a. Because the second grille blades 212 are parallel, they can more effectively guide airflow in a predetermined direction, helping to ensure consistent airflow direction across the entire air outlet grille 21 and avoiding uneven airflow or directional deviation.

[0120] In some embodiments, as Figure 9 and Figure 10 As shown, the indoor unit 101 also includes a first air guide plate assembly 3, which includes a first air guide plate 31. The first air guide plate 31 is rotatably connected to the air outlet 2a of the panel. The rotation axis of the first air guide plate 31 extends in the horizontal direction, and the first air guide plate 31 rotates to adjust the vertical air outlet direction.

[0121] When the air conditioner 100 is in cooling mode, the first air guide plate 31 can rotate between the first state and the second state. When the first air guide plate 31 is in the first state, the air outlet side of the first air guide plate 31 is tilted upward to guide the airflow upward. When the first air guide plate 31 is in the second state, the air outlet side of the first air guide plate 31 extends horizontally or tilts downward to guide the airflow horizontally or downward.

[0122] The first state refers to the maximum cold air delivery state of the air conditioner 100 in cooling mode. That is, when a high intensity of cold air is required in the air supply system of the air conditioner 100, the opening degree of the air damper is adjusted so that the air supply system can reach its maximum ventilation volume. The second state refers to the minimum cold air delivery state of the air conditioner 100 in cooling mode. That is, in order to maintain a certain air circulation volume and avoid excessive energy consumption and noise in the air supply system of the air conditioner 100, the air damper is adjusted to the minimum opening state. This is intended to ensure that the system can operate in an efficient and stable manner when the minimum ventilation volume is required.

[0123] It is understood that the upward and downward airflow in this embodiment are the same as those in the above embodiments. That is, both upward and downward airflow are based on the horizontal direction. Upward deflection in the horizontal direction is upward airflow, and downward deflection in the horizontal direction is downward airflow.

[0124] Thus, the first air guide plate 31 is rotatably connected to the air outlet 2a of the panel, and its rotation axis extends horizontally, allowing the user to easily adjust the vertical air outlet direction by rotating the first air guide plate 31. When the air conditioner 100 is in cooling mode, the first air guide plate 31 can rotate freely between the first and second states, guiding the airflow upward, horizontally, or downward respectively, meeting the airflow adjustment requirements under different needs. When the first air guide plate 31 is in the first state, its air outlet side is tilted upward, which can effectively deliver cold air to a higher position in the room, achieving a more uniform indoor temperature distribution and avoiding condensation problems caused by excessive temperature difference between the top of the room and the air outlet 2a of the panel. When the first air guide plate 31 is in the second state, its air outlet side extends horizontally or tilts downward, which can guide air to flow to all corners of the room, reducing temperature differences and dead zones, allowing the room to reach the preset temperature more quickly.

[0125] In some embodiments, the first air guide plate 31 also includes a closed state. When the first air guide plate 31 is in the closed state, the first air guide plate 31 is parallel to the vertical direction, and the rotation axis of the first air guide plate 31 is located above the air outlet 2a of the panel. The surface of the first air guide plate 31 facing the air outlet 1a of the housing is the inner surface 31a. The rotation angle of the first air guide plate 31 in the cooling mode is 43 degrees to 102 degrees.

[0126] When the first air guide plate 31 is in the closed state, that is, when there is no need for the first air guide plate 31 to adjust the airflow direction in the vertical direction, the first air guide plate 31 is closed. The first air guide plate 31 being parallel to the vertical direction means that the first air guide plate 31 covers part of the panel air outlet 2a, making the overall appearance of the air conditioner 100 more concise and streamlined. At the same time, it can also protect the internal components of the indoor unit 101. Adjusting the first air guide plate 31 to the closed state can effectively prevent dust, debris, etc. from entering the indoor unit 101, thereby extending the service life of the indoor unit 101 and reducing maintenance costs.

[0127] That is to say, when the first air guide plate 31 rotates at its minimum angle in the cooling mode, the angle between the inner surface 31a of the first air guide plate 31 and the vertical direction is 43 degrees, and when the first air guide plate 31 rotates at its maximum angle in the cooling mode, the angle between the inner surface 31a of the first air guide plate 31 and the vertical direction is 102 degrees.

[0128] When in cooling mode, if the angle between the inner surface 31a of the first air guide plate 31 and the vertical direction is less than 43 degrees, it may not be able to effectively direct cold air to the far end or upper part of the room, resulting in uneven temperature distribution. Simultaneously, an excessively small angle may restrict the range of airflow, ensuring that only the area near the panel air outlet 2a receives sufficient cold air, while other areas may not receive any. Because the air cannot effectively diffuse throughout the room, the air conditioner 100 may need to run for a longer time to reach the ideal temperature, which increases energy consumption and reduces the overall efficiency of the system.

[0129] When in cooling mode, if the angle between the inner surface 31a of the first air guide plate 31 and the vertical direction is greater than 102 degrees (i.e., the first air guide plate 31 is tilted upwards to more than 102 degrees), the cold air may be guided more towards the ceiling rather than diffused to the corners of the room. This may result in a higher temperature in the lower part of the room and an excessively low temperature in the upper part, creating an uncomfortable temperature gradient. Furthermore, in extreme cases, if the angle of the first air guide plate 31 is too large and its installation position is improper (such as near obstacles on the ceiling or wall), it may obstruct airflow or even cause the first air guide plate 31 to collide with the panel 2 or the wall, resulting in damage to the first air guide plate 31.

[0130] like Figure 11As shown, taking the angle between the inner surface 31a of the first air guide plate 31 and the vertical direction as 100 degrees as an example, when the first air guide plate 31 is in the first state, the angle between the inner surface 31a of the first air guide plate 31 and the vertical direction is 100 degrees, which is the maximum air supply position when the air conditioner is cooling. This helps to optimize indoor air circulation. When the first air guide plate 31 is tilted upward at a 100-degree angle, it can guide the air to a higher position in the room, thereby promoting air circulation throughout the room and helping to achieve a more uniform indoor temperature distribution. At the same time, when the first air guide plate is tilted upward at a 100-degree angle, the upward tilted air can reduce the discomfort caused by direct airflow. Especially in summer, the upward tilted air can prevent cold air from blowing directly on the human body, reducing the risk of health problems such as colds and joint pain.

[0131] like Figure 12 As shown, taking the angle between the inner surface 31a of the first air guide plate 31 and the vertical direction as 45 degrees as an example, when the first air guide plate 31 is in the second state, the angle between the inner surface 31a of the first air guide plate 31 and the vertical direction is 45 degrees. The 45-degree angle between the inner surface 31a of the first air guide plate 31 and the vertical direction is a state where, in order to maintain a certain airflow while avoiding excessive energy consumption and noise, the damper is adjusted to its minimum opening. This allows for more effective guidance of cool air to all corners of the room, helping to reduce temperature differences and dead zones, resulting in a more uniform decrease in indoor temperature. It also prevents large volumes of cold air from blowing directly on people, thus improving user comfort while meeting temperature requirements.

[0132] Taking the angle between the inner surface 31a of the first air guide plate 31 and the vertical direction, which is between 43 degrees and 102 degrees, as an example, within this angle range, the first air guide plate 31 can effectively guide the cold air to all corners of the room, thereby ensuring that the entire room receives a uniform distribution of cold air, improving the overall cooling uniformity, helping to improve cooling efficiency, reduce energy consumption, and provide users with a more comfortable indoor environment. It also ensures that the cold air flows into the indoor space in the optimal way, thus reaching the ideal indoor temperature more quickly. This not only improves the cooling speed but also enhances the cooling effect, allowing users to feel cool in a shorter time, thus contributing to improved overall user satisfaction and comfort.

[0133] In some embodiments, as Figure 9 and Figure 10 As shown, the first air guide plate 31 is rotatably connected to the air outlet of the panel. The rotation axis of the first air guide plate 31 extends in the horizontal direction. The first air guide plate 31 rotates to adjust the vertical air outlet direction. When the air conditioner 100 is in heating mode, the first air guide plate 31 can rotate between the first state and the second state. When the first air guide plate 31 is in the first state or the second state, the air outlet side of the first air guide plate 31 is tilted downward.

[0134] In this embodiment, the first state and the second state are different from those in the above embodiments. In this embodiment, the first state refers to the minimum hot air delivery state when the air conditioner 100 is in heating mode, and the second state refers to the maximum hot air delivery state when the air conditioner 100 is in heating mode.

[0135] In this way, when the air conditioner 100 is in heating mode, the air outlet side of the first air guide plate 31 is always tilted downwards, which can more effectively guide the hot air to the lower position of the room. This avoids the hot air blowing directly onto the ceiling or upper space, reduces the accumulation and waste of heat at the top of the room, makes the indoor temperature more uniform, improves the heating effect of the air conditioner 100, and provides users with a more comfortable and warm indoor environment.

[0136] In some embodiments, the first air guide plate 31 includes a closed state. When the first air guide plate 31 is in the closed state, it is parallel to the vertical direction, and its rotation axis is located above the air outlet 2a of the panel. The surface of the first air guide plate 31 facing the air outlet 1a of the housing is the inner surface 31a. The rotation angle of the first air guide plate 31 in heating mode is 23 degrees to 67 degrees. The closed state of the first air guide plate 31 in this embodiment is the same as that described in the above embodiments, and will not be repeated here.

[0137] That is to say, when the first air guide plate 31 rotates at its minimum angle in the heating mode, the angle between the inner surface 31a of the first air guide plate 31 and the vertical direction is 23 degrees, and when the first air guide plate 31 rotates at its maximum angle in the heating mode, the angle between the inner surface 31a of the first air guide plate 31 and the vertical direction is 67 degrees.

[0138] When in heating mode, if the angle between the inner surface 31a of the first air guide plate 31 and the vertical direction is less than 23 degrees, the excessively small downward tilt angle will cause a large temperature difference between the upper and lower parts of the room, with the upper part being warmer and the lower part being cooler. This uneven temperature distribution will reduce the heating effect and may cause users to feel uncomfortable. In addition, the excessively small downward tilt angle may hinder the natural circulation of air, causing vortices or dead corners to form in the room, further affecting the heating effect of the air conditioner 100 and the user experience.

[0139] In heating mode, when the angle between the inner surface 31a of the first air guide plate 31 and the vertical direction is greater than 67 degrees, and when the first air guide plate 31 tilts upwards to an angle exceeding 67 degrees vertically, hot air may be directed more towards the top or walls of the room, rather than spreading to the various corners. This results in a lower temperature in the lower part of the room and a higher temperature in the upper part, creating an uncomfortable temperature gradient. The inability to effectively distribute hot air throughout the room causes the air conditioner 100 to operate more frequently to maintain the indoor temperature, thus reducing heating efficiency.

[0140] like Figure 14 As shown, taking the angle between the inner surface 31a of the first air guide plate 31 and the vertical direction as 25 degrees as an example, when the first air guide plate 31 is in the first state, the angle between the inner surface 31a of the first air guide plate 31 and the vertical direction is 25 degrees, that is, the first air guide plate 31 is in the minimum hot air delivery state, which can ensure that the hot air can be evenly distributed in the lower position of the room. At this time, the hot air delivery volume is small. The angle between the first air guide plate and the vertical direction is 25 degrees to maintain the even delivery of hot air into the room, avoiding the dryness and discomfort caused by the hot air blowing directly on the human body, and improving the thermal comfort of the user when using the air conditioner.

[0141] like Figure 13 As shown, taking the angle between the inner surface 31a of the first air guide plate 31 and the vertical direction as 65 degrees as an example, when the first air guide plate 31 is in the second state, the angle between the inner surface 31a of the first air guide plate 31 and the vertical direction is 65 degrees, that is, the first air guide plate 31 is in the maximum hot air delivery state. The 65-degree angle allows the first air guide plate 31 to deliver air to a wider space, especially in high-ceilinged indoor environments. This design ensures that hot air can cover every corner of the room, improving the uniformity of indoor temperature. When the first air guide plate 31 is tilted at a 65-degree angle, it can more effectively guide airflow and form stronger air convection, which helps to accelerate the rate of change in indoor temperature, allowing the air conditioner to reach the required indoor temperature in a shorter time. This not only helps to save energy but also significantly improves the heating efficiency of the air conditioner. Furthermore, the 65-degree angle prevents hot air from blowing directly onto the human body and causing discomfort, and also prevents the hot air from deviating too far from the target area, thus achieving a better air delivery effect.

[0142] Taking the angle between the inner surface 31a of the first air guide plate 31 and the vertical direction, which is between 23 and 67 degrees, as an example, within this angle range, the first air guide plate 31 can effectively guide hot air to all corners of the room, especially the lower area, thereby ensuring a uniform heat distribution throughout the room. This helps improve heating efficiency, reduce energy consumption, and provide users with a more comfortable indoor environment. It also ensures that hot air flows into the indoor space in the optimal way, thus reaching the ideal indoor temperature more quickly. This not only improves the heating speed but also enhances the heating effect, allowing users to feel warmth in a shorter time.

[0143] In some embodiments, combined with Figure 9 and Figure 10 The indoor unit 101 also includes a second air guide plate 4, which is disposed at the panel air outlet 2a. The second air guide plate 4 can rotate in the horizontal direction to adjust the horizontal air outlet direction. That is to say, a second air guide plate 4 that can rotate in the horizontal direction is also provided at the panel air outlet 2a for adjusting the air outlet direction in the horizontal direction.

[0144] In this way, the second air guide plate 4 can rotate freely in the horizontal direction, allowing users to precisely adjust the horizontal air supply direction as needed. This ensures that the air conditioning air can evenly cover the entire room in the horizontal direction, avoiding situations where certain areas are too cold or too hot in the horizontal direction. This improves the comfort and efficiency of the air conditioner 100 and optimizes the airflow distribution in the room.

[0145] In some embodiments, as Figure 9 and Figure 10 As shown, the indoor unit 101 also includes a third air guide plate 32, which is attached to the lower side of the panel 2.

[0146] The third air guide plate 32 can switch between an open state and a closed state. When the third air guide plate 32 is in the closed state, it blocks the air outlet 2a of the panel. When the third air guide plate 32 is opened to the maximum state, it is located below the housing 1.

[0147] Thus, when the third air guide plate 32 is in the open state, it can swing vertically to change the vertical airflow direction, preventing the airflow from directly hitting the human body and avoiding cold or hot air blowing directly on them, thereby reducing discomfort. When the third air guide plate 32 is in the closed state, it completely blocks the panel air outlet 2a, allowing the panel 2 to blend seamlessly with the interior ceiling support, making the air conditioner's appearance more aesthetically pleasing. The third air guide plate 32 also prevents dust particles and debris from entering the indoor unit 101 through the panel air outlet 2a, ensuring the service life of the indoor unit 101. Furthermore, the fact that the third air guide plate 32 is located below the casing 1 means that when the third air guide plate 32 is opened to its maximum angle, it will not interfere with the ceiling bracket used to install the air conditioner 100. When the third air guide plate 32 is opened to its maximum angle, it can significantly enhance the downward air supply effect, which helps to form a better air convection circulation, so that cold or hot air can circulate more effectively in the room, reduce temperature stratification, and make the indoor temperature more uniform.

[0148] Optionally, combined Figure 8 and Figure 10 The indoor unit 101 also includes a drive assembly 5, which is disposed on the panel 2 and is configured to drive the first air guide plate 31, the second air guide plate 4 and the third air guide plate 32 to rotate.

[0149] Thus, by simultaneously controlling the rotation of the first air guide plate 31, the second air guide plate 4, and the third air guide plate 32 through the drive component 5, a more complex and precise air delivery mode can be achieved. This allows the air conditioner 100 to adjust the angle of each air guide plate according to the user's actual needs, thereby achieving all-round air delivery coverage. Furthermore, the precise control of the drive component 5 allows the air guide plates to remain at any desired angle, ensuring the accuracy of the air delivery direction and helping to meet the user's personalized needs for indoor temperature distribution.

[0150] It should be noted that the driving component 5 that drives the first air guide plate 31, the second air guide plate 4 and the third air guide plate 32 to rotate can be a motor, a cylinder or other components that can drive the air guide plates to rotate. This embodiment does not make specific limitations on this.

[0151] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although 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.
