Description

Technical Field

[0001] This disclosure relates to the field of air conditioner technology, and more specifically, to an air conditioner. Background Technology

[0002] In related technologies, indoor air conditioners consist of a fan, air inlet, air outlet, and heat exchanger. They deliver air for cooling and heating through a guide vane. However, the aforementioned air delivery method is limited in its single air delivery pattern, making it difficult to meet the requirements of cold air being delivered from top to bottom during cooling and hot air being delivered from bottom to top during heating. This can easily lead to problems such as cold air blowing directly on people and hot air not being able to reach the ground during air conditioner operation, resulting in poor user comfort. Utility Model Content

[0003] The purpose of this disclosure is to provide an air conditioner capable of reversible air supply in two different air supply directions, adapting to the air outlet requirements of different air directions under heating and cooling conditions, so as to at least partially solve the problems in the related art.

[0004] To overcome the problems existing in the related art, a first aspect of the present disclosure provides an air conditioner, comprising: The shell includes a first chamber and a second chamber. The first chamber is equipped with a heat exchanger and a first opening communicating with the outside. The second chamber is provided with a fan assembly, a second opening communicating with the first chamber, a third opening communicating with the outside, and an air duct. The air duct includes a first connecting port communicating with the fan assembly, a second connecting port communicating with the first chamber, and a third connecting port communicating with the outside. The third opening and the third connecting port are parallel in orientation, but the third opening is different in orientation from the first opening. A fan assembly for opening and closing the second opening and the third opening, and for selectively connecting the fan assembly to the second or the third communication port to change the airflow direction within the housing.

[0005] In some possible implementations, the air conditioner includes a first air supply state and a second air supply state. When the air conditioner is in the first air supply state, the air vane assembly controls the second opening to open and the third opening to close, and the fan assembly is connected to the third communication port. When the air conditioner is in the second air supply state, the air vane assembly controls the second opening to close and the third opening to open, and the fan assembly is connected to the second communication port. Thus, the air conditioner mainly includes cooling and heating modes. To adapt to the cooling and heating requirements of the air conditioner, the air conditioner includes a first air supply state and a second air supply state. The first air supply state adapts to the heating mode of the air conditioner, and the second air supply state adapts to the cooling mode of the air conditioner.

[0006] In some possible implementations, one of the first opening and the third opening is located on the side wall of the housing, and the other is located on the bottom wall of the housing. This defines the positions of the first and third openings of the air conditioner, thereby enabling a specific manner in which the first air supply state is bottom air intake and top air outlet, and the second air supply state of the air conditioner is bottom air outlet and top air intake.

[0007] In some possible implementations, there can be multiple second and third openings, and the second openings and at least some of the third openings are correspondingly arranged. Thus, by limiting the number of second and third openings, airflow between the second chamber and the first chamber, or airflow between the second chamber and the outside, can be accelerated. Furthermore, the corresponding arrangement of the second openings and at least some of the third openings facilitates the opening or closing of the air intake assembly.

[0008] In some possible implementations, the air duct assembly includes a first air duct mechanism and a second air duct mechanism. The first air duct mechanism is disposed on a partition between the first chamber and the second chamber, and is used to selectively control the opening of the second opening and the third opening. The second air duct mechanism is disposed in the air duct, and is used to selectively control the first connecting port to connect with the second connecting port or the third connecting port. Thus, by controlling the first air duct mechanism and the second air duct mechanism, the air conditioner can easily switch between a first air supply state and a second air supply state.

[0009] In some possible implementations, the first air deflector mechanism includes a first driving member, a first rotating shaft, and a first air deflector. The first air deflector is fixedly mounted on the first rotating shaft, which is rotatably mounted on the housing. The first driving member drives the first rotating shaft to rotate, thereby causing the first air deflector to flip and selectively open either the second opening or the third opening. Thus, the first air deflector structure is specifically defined as including a first driving member, a first rotating shaft, and a first air deflector. The first driving member drives the first rotating shaft to rotate, causing the first air deflector to flip, thereby enabling the selective opening or closing of the corresponding second opening or first air outlet.

[0010] In some possible implementations, the second air deflector mechanism includes a second driving member, a second rotating shaft, and a second air deflector. The second air deflector is fixed to the second rotating shaft, which is rotatably disposed in the air duct. The second driving member drives the second rotating shaft to rotate, thereby causing the second air deflector to flip and selectively control the first connecting port to connect with the second connecting port or the third connecting port. Thus, the second air deflector mechanism is specifically defined as including a second driving member, a second rotating shaft, and a second air deflector. The second driving member drives the second rotating shaft to rotate, thereby causing the second air deflector to flip and selectively control the first connecting port to connect with the second connecting port or the third connecting port.

[0011] In some possible implementations, the second opening includes a frame extending into the second chamber, the second rotating shaft rotatably passing through the frame and extending into the air duct, and the second drive member driving the second rotating shaft to rotate to move the second air vane. Thus, the frame design improves the sealing between the second air vane and the second opening when the second air vane is flipped, facilitates the installation of the second rotating shaft, and enhances the stability of the second rotating shaft during rotation.

[0012] In some possible implementations, the second air vane is an arc-shaped air vane. Thus, by setting the air vane in an arc shape, wind resistance can be reduced and air delivery efficiency improved.

[0013] In some possible implementations, the fan assembly includes a centrifugal fan, which includes a volute and an inlet and an outlet disposed on the volute. The inlet communicates with the second chamber, and the outlet communicates with the first connection port of the air duct. Thus, the centrifugal fan facilitates the provision of power to the air conditioner in both the first and second air supply states.

[0014] In some possible implementations, the fan assembly includes a centrifugal fan, with at least a portion of the centrifugal fan's casing forming the air duct. Thus, by forming the air duct with at least a portion of the centrifugal fan's casing, sealing performance can be improved, structural stability enhanced, and airflow efficiency optimized.

[0015] In some possible implementations, there are multiple centrifugal fans, and these multiple centrifugal fans share a single third drive motor. Thus, by using multiple centrifugal fans, the total air volume of the air conditioner can be increased, thereby satisfying the air supply requirements of the air conditioner in either the first or second air supply state.

[0016] In some possible implementations, multiple centrifugal fans are spaced apart, with at least a portion of the second opening and / or the third opening located between adjacent centrifugal fans. This allows air to enter the centrifugal fans rapidly.

[0017] In some possible implementations, the inlet of the volute is located between two adjacent second openings; and / or, The inlet of the volute is located between two adjacent third openings. This allows air to enter the centrifugal fan quickly.

[0018] In some possible implementations, the heat exchanger has a straight or V-shaped cross-section; and / or, The air conditioner also includes a drip tray located below the heat exchanger. By using a straight or V-shaped cross-section for the heat exchanger, the contact area between the air and the heat exchanger is increased, improving heat exchange efficiency. Furthermore, the drip tray collects condensate, preventing leaks that could cause electrical malfunctions in the fan and enhancing the air conditioner's reliability.

[0019] In some possible implementations, the air conditioner is a ducted air conditioner. This limits the air conditioner to the specific application scenario of a ducted air conditioner.

[0020] The above technical solution includes a housing comprising a first chamber and a second chamber. The first chamber is equipped with a heat exchanger and a first opening communicating with the outside. The second chamber is equipped with a fan assembly, a second opening communicating with the first chamber, a third opening communicating with the outside, and an air duct. The air duct includes a first connecting port communicating with the fan assembly, a second connecting port communicating with the first chamber, and a third connecting port communicating with the outside. The third opening and the third connecting port are parallel in orientation, while the first opening and the third opening are oriented differently. The air conditioner also includes a fan plate assembly, which controls the opening and closing of the second and third openings and allows the fan assembly to selectively communicate with either the second or third connecting port of the air duct, thereby enabling the air conditioner to have two air supply directions and reversible air supply. For example, the air deflector assembly can control the second opening to open and the third opening to close, and control the fan assembly to selectively connect with the third connection port of the air duct. In this case, air enters the second chamber through the first opening and the second opening, and then enters the fan assembly through the inlet before exiting through the third connection port of the air duct. Alternatively, the air deflector assembly can control the second opening to close and the third opening to open, and control the fan assembly to selectively connect with the second connection port of the air duct. In this case, air enters the second chamber through the third opening, enters the fan assembly through the inlet, enters the first chamber through the second connection port of the air duct, and then exits through the first opening. In this way, the air supply mode can be selected according to different operating conditions of the air conditioner, improving the user experience.

[0031] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0032] In this disclosure, unless otherwise stated, directional terms such as "up and down" are used; please refer to [the relevant documentation / reference]. Figure 1 For details on the "top and bottom" and "front and back" directions, please refer to [the relevant documentation / reference]. Figure 1 The front-back direction in the text. "Inner" and "outer" refer to the outline of the corresponding component itself.

When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0033] The inventors discovered that indoor air conditioners consist of a casing, a fan, an air inlet, an air outlet, and a heat exchanger. They deliver air during cooling and heating by means of a guide vane. However, the above-mentioned air delivery method has the disadvantage of being too simple and unable to meet the requirements of cold air being delivered from top to bottom when the air conditioner is cooling and hot air being delivered from bottom to top when the air conditioner is heating. This can easily cause problems such as cold air blowing directly on people and hot air not being able to reach the ground during the operation of the air conditioner, resulting in poor user comfort.

[0034] To solve the above technical problems, such as Figures 1 to 7 As shown, this disclosure provides an air conditioner, including: a housing 1, a heat exchanger 2, a fan assembly 3, an air duct 4, and an air deflector assembly 5. The housing 1 includes a first chamber 11 and a second chamber 12. The first chamber 11 is provided with the heat exchanger 2 and a first opening 13 communicating with the outside. The second chamber 12 is provided with the fan assembly 3, a second opening 14 communicating with the first chamber 11, a third opening 15 communicating with the outside, and the air duct 4. The air duct 4 includes a first connecting port 41 communicating with the fan assembly 3, a second connecting port 42 communicating with the first chamber 11, and a third connecting port 43 communicating with the outside. The third opening 15 and the third connecting port 43 are parallel in orientation, and the third opening 15 has a different orientation than the first opening 13. The air deflector assembly 5 is used to open and close the second opening 14 and the third opening 15, and to selectively connect the fan assembly 3 with either the second connecting port 42 or the third connecting port 43 to change the airflow direction within the housing 1.

[0035] The above technical solution includes a first chamber 11 and a second chamber 12 in the housing 1. The first chamber 11 is equipped with a heat exchanger 2 and a first opening 13 communicating with the outside. The second chamber 12 is equipped with a fan assembly 3, a second opening 14 communicating with the first chamber 11, a third opening 15 communicating with the outside, and an air duct 4. The air duct 4 includes a first connecting port 41 communicating with the fan assembly 3, a second connecting port 42 communicating with the first chamber 11, and a third connecting port 43 communicating with the outside. The third opening 15 and the third connecting port 43 are parallel in orientation, while the first opening 13 and the third opening 15 are in different orientations. The air conditioner also includes a fan plate assembly 5, which controls the opening and closing of the second opening 14 and the third opening 15, and allows the fan assembly 3 to selectively communicate with the second connecting port 42 or the third connecting port 43 of the air duct 4, thereby enabling the air conditioner to have two air supply directions and reversible air supply. For example, the air deflector assembly 5 can control the second opening 14 to open and the third opening 15 to close, and control the fan assembly 3 to selectively connect with the third connecting port 43. At this time, air enters the second chamber 12 from the first opening 13 through the first chamber 11 and the second opening 14, and then enters the fan assembly 3 through the inlet and exits from the third connecting port 43 of the air duct 4. The air deflector assembly 5 can also control the second opening 13 to close and the third opening 15 to open, and control the fan assembly 3 to selectively connect with the second connecting port 42 of the air duct 4. At this time, air enters the second chamber 12 from the third opening 15, enters the air duct 4 from the inlet of the fan assembly 3, enters the first chamber 11 through the second connecting port 42, and exits from the first opening 13. In this way, the air supply mode can be selected according to different operating conditions of the air conditioner, improving the user experience.

[0036] Air conditioners mainly include cooling and heating modes. To adapt to the requirements of cooling and heating modes, in some possible implementations, the air conditioner includes a first air supply state and a second air supply state. The first air supply state is adapted to the heating mode, and the second air supply state is adapted to the cooling mode. When the air conditioner is in the first air supply state, the fan assembly 5 controls the second opening 14 to open and the third opening 15 to close. The fan assembly 3 is connected to the third connecting port 43. At this time, air enters the first chamber 11 through the first opening 13 and enters the second chamber 12 through the second opening 14, then enters the fan assembly 3 through the inlet, and finally passes through the third connecting port 43. When the air conditioner is heating, the air is drawn in from the top and discharged from the bottom, creating a carpet-like airflow that rapidly heats the indoor air and improves the user experience. When the air conditioner is in the second air supply state, the fan assembly 5 controls the second opening 14 to close and the third opening 15 to open. The fan assembly 3 is connected to the second connecting port 42. At this time, air enters the second chamber 12 through the third opening 15 and then enters the fan assembly 3 through the inlet of the fan assembly 3. After that, it enters the first chamber 11 through the second connecting port 42 of the air duct 4 and is finally discharged into the room through the first opening 13. This allows the air conditioner to cool down by creating a curtain-like airflow that draws in from the bottom and discharges from the top, rapidly cooling the indoor air and improving the user experience.

[0037] Understandably, in cooling mode, an air conditioner needs to adapt to a bottom-intake, top-outtake configuration to allow cool air to flow downwards, creating a "sky curtain" effect. This means that when cooling, the air conditioner directs cool air downwards. Since cool air is denser, it naturally sinks after being expelled from above, creating a complete convection cycle with the bottom-intake configuration, allowing the indoor space to cool down quickly. Furthermore, the downward diffusion of cool air prevents localized areas from becoming too cold or too hot, reducing perceived temperature differences. Similarly, when heating, the air conditioner can adapt to a bottom-outtake, top-intake configuration to allow warm air to flow upwards, creating a "carpet" effect. This means that when heating, the air conditioner directs warm air upwards. Since warm air is less dense, it naturally rises. The rising of warm air and the sinking of cool air, combined with the bottom-outtake configuration, create a complete convection cycle, allowing heat to evenly cover the entire space. This prevents warm air from accumulating on the ceiling, improving heating efficiency. Additionally, the upward airflow reduces the perceived temperature difference between the upper and lower parts of the room, which can occur with a single top-outtake configuration, thus improving the user experience.

[0038] In some possible implementations, the housing 1 can be a rectangular body, consisting of a top wall, a bottom wall, and four side walls connected end to end. The top wall, bottom wall 17, and side walls can all be made of steel plates or acrylic plates. The housing is divided into a first chamber 11 and a second chamber 12 by a partition 16 in the middle. The second opening 14 and the second connecting port 42 are both located on the partition 16. In order to enable the air conditioner to blow air in different directions, one of the first opening 13 and the third opening 15 is located on the side wall of the housing 1, and the other is located on the bottom wall of the housing 1.

[0039] For example, such as Figure 1 As shown, the first opening 13 can be located on the front side wall of the housing 1, the second opening 14 and the second connecting port 42 are both provided on the partition 16, and the third opening 15 and the third connecting port 43 are provided on the bottom wall 17 of the housing 1. In this case, as Figure 1 As shown, the front is the direction closer to the interior, the rear is the direction away from the interior, the top is the side away from the ground, and the bottom is the side closer to the ground. In this embodiment, the front sidewall refers to the side closer to the interior. Thus, the first opening 13 is located above the third opening 15 or the third connecting opening 43. Therefore, when the air conditioner is in cooling mode, as... Figure 7 As shown, air enters the second chamber 12 through the third opening 15, passes through the fan assembly 3, and enters the first chamber 11 through the second connecting port 42. Finally, it is exhausted into the room through the first opening 13. Thus, cold air is exhausted from the upper first opening 13 and flows into the room, forming a ceiling breeze. The cold air sinks, and together with the air intake through the lower third opening 15, a complete convection cycle is formed, allowing the indoor space to cool down rapidly. When the air conditioner is in heating mode, as... Figure 6 As shown, air enters the first chamber 11 through the first opening 13 and then enters the second chamber 12 through the second opening 14 before entering the fan assembly 3. Finally, it is discharged into the room through the third connecting port 43 of the air duct 4. In this way, hot air enters the room through the second air outlet 43 at the bottom, and the hot air flows from bottom to top to form a carpet-like airflow. This achieves the effect of hot air being discharged from bottom to top when the air conditioner is heating. Hot air has a lower density and will naturally rise. Hot air rises and cold air sinks. The air outlet at the bottom, combined with the air inlet at the top, can form a complete convection cycle, allowing heat to evenly cover the entire space. This avoids hot air being directly discharged and accumulating on the ceiling, improving heating efficiency and enhancing the user experience.

[0040] In some possible implementations, to maintain the stability of airflow from the two different air supply methods, the third connecting port 43 and the third opening 15 face the same direction, such as... Figure 3 , Figure 4 and Figure 7As shown, the third connecting port 43 and the third opening 15 are both located on the bottom wall 17 of the second chamber 12, so that the opening orientation of the third connecting port 43 and the third opening 15 is the same. When the air conditioner switches between cooling and heating, the path length of the bidirectional airflow is roughly the same, reducing the resistance difference. Thus, in the first air supply state and the second air supply state of the air conditioner, the air supply stability of the two different air supply modes can be maintained, avoiding pressure fluctuations and eddy currents during switching.

[0041] Of course, in some possible implementations, such as Figures 1 to 7 As shown, the second opening 14 and the second connecting port 42 are both located on the partition 16, and the openings of the two can face the same direction. In this way, when the air conditioner switches between cooling and heating, the path length of the bidirectional airflow can be kept roughly the same, reducing the resistance difference. Thus, in the first and second air supply states of the air conditioner, the air supply stability of the two different air supply modes can be maintained, avoiding pressure fluctuations and eddy interference during switching.

[0042] Understandably, in some feasible methods, in order to further improve the stability of airflow, the third connecting port 43 and the third opening 15 have the same opening orientation, and the second opening 14 and the second connecting port 42 have the same opening orientation. This further limits the path length of bidirectional airflow, reduces the airflow resistance difference, and thus maintains the stability of airflow in the first and second airflow states of the air conditioner, avoiding pressure fluctuations and eddy interference during switching.

[0043] Of course, the fact that the third connecting port 43 and the third opening 15 have the same opening direction and that the second opening 14 and the second connecting port 42 have the same opening direction is illustrative. In other embodiments, the opening directions of the third connecting port 43 and the third opening 15 can also be different. For example, the third connecting port 43 can be located on the housing 1 at the lower part of the side wall, which is different from the first opening 13. That is, the third connecting port 43 is also located below the first opening 13. When the air conditioner is heating, it can also form a carpet-like airflow with downward air outlet and upward air intake, improving the user experience. In addition, the opening directions of the second opening 14 and the second connecting port 42 can also be different. The second opening 14 is located on the partition 16 and faces the direction of the first opening 13. The opening of the second connecting port 42 can be tilted upward or downward, which is the same as the orientation of the second opening 14.

[0044] Of course, in some feasible ways, the first opening 13, the second opening 14, and the second connecting port 42 can also be oriented in the same direction, thereby further reducing the path length of the bidirectional airflow, maintaining the airflow stability of the two different air supply methods, and avoiding pressure fluctuations and vortex interference during switching.

[0045] To accelerate airflow within the housing 1, in some possible embodiments, the number of second openings 14 and third openings 15 may be multiple, and the second openings 14 and at least a portion of the third openings 15 may be correspondingly arranged. For example... Figure 7 As shown, there are three second openings 14, which are spaced apart on the partition 16. There are also three third openings 15, which are spaced apart on the bottom wall 17 of the housing 1. Thus, the arrangement of the three third openings 15 facilitates the entry of external air into the second chamber 12, and the arrangement of the three second openings 14 facilitates the airflow in the first chamber 11 and the second chamber 12. For example, in the first air supply state of the air conditioner, air enters the first chamber 11 through the first opening 13, enters the second chamber 12 through the three second openings 14, and then enters the third connecting port 43 of the air duct 4 through the corresponding fan assembly 3 and is discharged into the room. In the second air supply state of the air conditioner, air enters the second chamber 12 through multiple three third openings 15, enters the first chamber 11 through the second connecting port 42 of the air duct 4 through the corresponding fan assembly 3, and is discharged into the room through the first opening 13.

[0046] It is understood that the above-mentioned number of three second openings 14 and three third openings 15 is an illustrative example. In other embodiments, the number of second openings 14 and third openings 15 can be other values. For example, the number of second openings 14 can be two, and the number of third openings 15 can also be two. Of course, the number of second openings 14 and the number of third openings 15 can not be equal. For example, the number of second openings 14 can be two, and the number of third openings 15 can be three.

[0047] In some possible implementations, the air deflector assembly 5 includes a first air deflector mechanism 51 and a second air deflector mechanism 52. The first air deflector mechanism 51 is disposed on the partition 16 between the first chamber 11 and the second chamber 12. The first air deflector mechanism 51 selectively controls the opening of the second opening 14 and the third opening 15. The second air deflector mechanism 52 is disposed in the air duct 4. The second air deflector mechanism 52 selectively controls the fan assembly 3 to connect with either the second connecting port 42 or the third connecting port 43. Thus, by configuring the first air deflector mechanism 51 and the second air deflector mechanism 52, the air conditioner can be selectively adjusted to a second air supply state to adapt to the cooling mode, or selectively adjusted to a first air supply state to adapt to the heating mode, depending on the cooling or heating operation of the air conditioner.

[0048] Of course, it is understandable that the first air deflector mechanism 51 and the second air deflector mechanism 52 mentioned above can be linked together. In this way, the first air supply state and the second air supply state of the air conditioner can be quickly switched. For example, when the first air deflector mechanism 51 controls the second opening 14 to open and the third opening 15 to close, the second air deflector mechanism 52 is linked, that is, the second air deflector mechanism 52 controls the fan assembly 3 to connect with the third connecting port 43. At this time, the air conditioner is adjusted to the first air supply state to adapt to the heating mode of the air conditioner. When the first air deflector mechanism 51 controls the second opening 14 to close and the third opening 15 to open, the second air deflector mechanism 52 is linked, that is, the second air deflector mechanism 52 controls the fan assembly 3 to connect with the second connecting port 42. At this time, the air conditioner is adjusted to the second air supply state to adapt to the cooling mode of the air conditioner.

[0049] In some possible implementations, such as Figures 3 to 5 As shown, the first air deflector mechanism 51 includes a first driving member 511, a first rotating shaft 512, and a first air deflector 513. The first air deflector 513 is fixedly mounted on the first rotating shaft 512, which is rotatably mounted on the housing 1. The first driving member 511 drives the first rotating shaft 512 to rotate, thereby causing the first air deflector 513 to flip and selectively control the opening of either the second opening 14 or the third opening 15. Wherein, as... Figure 4 and Figure 5 As shown, the first driving component 511 can be a first driving motor, which is a motor capable of forward or reverse rotation. The first rotating shaft 512 is rotatably disposed within the second chamber 12. For example, a bearing seat that mates with the first rotating shaft 512 can be provided on the bottom wall of the second chamber 12. The outer contour of the first air plate 513 is adapted to the second opening 14 and the third opening 15. Figure 3 In this configuration, there are three second openings 14 and three third openings 15, and they are arranged in a one-to-one correspondence. The first rotating shaft 512 is located close to the bottom wall 17 of the second chamber 12 and the connection between the partition 16. There are also three first air plates 513, which are respectively arranged between the corresponding second openings 14 and third openings 15. The first rotating shaft 512 is driven to rotate by the first drive motor to drive the first air plates 513 to flip, thereby selectively opening the three second openings 14 or opening the three third openings 15.

[0050] It is understandable that the opening sizes of the three second openings 14 mentioned above can be different, such as... Figure 3As shown, the second opening 14 in the middle of the partition 16 has a larger opening, while the second openings 14 on both sides of the partition 16 have smaller openings. This allows for full utilization of the space within the housing 1, facilitating ventilation in the first chamber 11 and the second chamber 12. It is understood that the opening sizes of the aforementioned second openings 14 can also be the same; for example, in some possible embodiments, the opening sizes of multiple second openings 14 can be equal. Similarly, the opening sizes of multiple third openings 15 can also be set with reference to the dimensions of the corresponding second openings 14.

[0051] In order for the first air plate 513 to be able to flip and seal the second opening 14 or the third opening 15, a frame extending toward the interior of the second chamber 12 can be provided at the second opening 14. The first air plate 513 fits against the frame at the second opening 14 as driven by the first drive motor, thereby closing the second opening 14. Of course, a frame extending toward the interior of the second chamber 12 can also be provided at the third opening 15. The first air plate 513 flips and fits against the frame at the third opening 15 as driven by the first drive motor, thereby closing the third opening 15.

[0052] Of course, in some feasible ways, each second opening 14 can be individually equipped with a first rotating shaft 512, a first air plate 513, and a first drive motor that drives the first air plate 513. In this case, each third opening 15 can also be individually equipped with a first rotating shaft 512, a first air plate 513, and a first drive motor that drives the first air plate 513. In this case, by individually controlling the first drive motor corresponding to the second opening 14 to drive the first rotating shaft 512 to rotate, the first air plate 51 will be rotated synchronously, thus opening or closing the second opening 14. Similarly, by individually controlling the first drive motor corresponding to the third opening 15 to drive the first rotating shaft 512, the first air plate 51 will be rotated synchronously, thus opening or closing the third opening 15.

[0053] To facilitate selective connection of the fan assembly 3 to the second connection port 42 or the third connection port 43, in some possible embodiments, such as Figures 3 to 6 As shown, the second air deflector mechanism 52 may include a second driving member 521, a second rotating shaft 522, and a second air deflector 523. The second air deflector 523 is fixed to the second rotating shaft 522, which is rotatably disposed in the air duct 4. The second driving member 521 drives the second rotating shaft 522 to rotate, thereby causing the second air deflector 523 to flip and selectively control the fan assembly 3 to connect with the second connecting port 42 or the third connecting port 43. Figures 3 to 6As shown, the second driving component 521 can be configured as a second driving motor. Referring to the first driving motor, the second driving motor can be a forward or reverse rotating motor. The second rotating shaft 522 is rotatably disposed in the air duct 4 and located between the second connecting port 42 and the third connecting port 43. One end of the second rotating shaft 522 passes through the side wall of the air duct 4 and is connected to the external second driving motor. The part of the second rotating shaft 522 located in the air duct 4 is provided with a second air plate 523. The second driving motor drives the second rotating shaft 522 to rotate, thereby causing the second air plate 523 to rotate. When the second air plate 523 is in contact with the second connecting port 42, the fan assembly 3 is connected to the third connecting port 43. When the second air plate 523 is in contact with the third connecting port 43, the fan assembly 3 is connected to the second connecting port 42, thereby facilitating the switching between the first air supply state and the second air supply state of the air conditioner.

[0054] Of course, in some feasible ways, in order to make full use of the space inside the housing 1 and improve the rotational stability of the second rotating shaft 522, a frame extending toward the interior of the second chamber 12 is provided on the second opening 14. The frame is close to the outer wall of the air duct 4. The second rotating shaft 522 can rotatably pass through the frame and extend into the air duct 4. The second air plate 523 is provided on the second rotating shaft 522 and located in the air duct 4. The second driving member 521 can be a second driving motor. The second driving motor is provided on the partition 16 and is connected to the second rotating shaft 522 in a transmission manner. Thus, the second rotating shaft 522 is driven to rotate by the second driving motor, which drives the second air plate 523 to flip so that the fan assembly 3 is connected to the second communication port 42 or the third communication port 43.

[0055] To facilitate the guidance of the air discharged from the fan assembly 3 into the second connecting port 42 and the third connecting port 43, in some possible embodiments, such as Figure 3 As shown, the second air vane 523 is an arc-shaped air vane with its opening facing the fan assembly 3. The arc shape allows the second air vane 523 to rotate when the second drive motor drives the second shaft 522, thus closing the second connecting port 42. At this time, the air discharged from the fan assembly 3 is discharged through the third connecting port 43. The arc shape of the second air vane 523 allows its curved surface to conform to the natural flow trajectory of the airflow, reducing airflow impact and eddy current generation, lowering wind resistance, and improving air delivery efficiency. Furthermore, when the second air vane 523 rotates and closes the third connecting port 43, the arc shape also forms a roughly horizontal air duct 4 with the sidewall inside the duct 4, allowing air to be discharged from the second connecting port 42.

[0056] Centrifugal fans feature high air pressure, strong airflow adaptability, low noise, and energy saving, and can be compatible with complex air ducts. In some feasible embodiments, the fan assembly 3 may include a centrifugal fan 31. The centrifugal fan 31 includes a volute 34 and an inlet 32 ​​and an outlet 33 disposed on the volute 34. The inlet 32 ​​communicates with the second chamber 12, and the outlet 33 communicates with the first connection port 41 of the air duct 4. Figure 7 As shown, the volute 34 of the centrifugal fan 31 is fixed on the bottom wall 17 of the second chamber 12. The inlet 32 ​​is located on the side of the volute 34. An impeller 35 is installed inside the volute 34 and is driven by a third drive motor 6. The air duct 4 is located between the partition plate 16 and the volute 34. The first connecting port 41 of the air duct 4 is connected to the outlet 33 on the volute 34. Part of the air duct 4 extends toward the partition plate 16 and intersects with the partition plate 16, forming a second connecting port 42 at the intersection. The second connecting port 42 is connected to the first chamber 11. Part of the air duct 4 extends toward the bottom wall 17 and intersects with the bottom wall 17, forming a third connecting port 43 at the intersection. The third connecting port 43 is connected to the outside. Thus, the centrifugal fan 31 allows external air to be introduced into the second chamber 12 through the third opening 15 and into the volute 34 through the inlet 32. The impeller 35 rotates, discharging the air through the second connecting port 42 of the duct 4 into the first chamber 11 and then through the first opening 13 into the room. Alternatively, after entering the first chamber 11 through the first opening 13, the air enters the second chamber 12 through the second opening 14 and then enters the volute 34 through the inlet 32 ​​of the centrifugal fan 31. The impeller 35 rotates, discharging the air through the third connecting port 43 in the duct 4 into the room.

[0057] To improve sealing performance, enhance structural stability, and optimize airflow efficiency, in some possible implementations, at least a portion of the volute 34 of the centrifugal fan 31 forms an air duct 4. For example, the outlet 33 of the volute 34 extends toward the partition 16 to form a partial air duct 4. In this case, the first connecting port 41 of the air duct 4 can coincide with the outlet 33 of the volute 34. The air duct 4 and the volute 34 can be connected by fasteners. By sharing a portion of the pipe, the stability of the connection between the air duct 4 and the volute 34 is enhanced, and the airflow efficiency is optimized, so that the air discharged from the outlet 33 of the volute 34 can be discharged through the second connecting port 42 or the third connecting port 43 of the air duct 4.

[0058] Of course, it is understandable that the aforementioned air duct 4 can also be integrally formed with the volute 34. That is, the outlet 33 of the volute 34 can extend in both directions toward the partition 16 and the bottom wall 17 to form an air duct 4 with a second connecting port 42 and a third connecting port 43. In this case, air enters the volute 34 through the inlet 32 ​​of the centrifugal fan 31 and is discharged through the corresponding second connecting port 42 or third connecting port 43. In this way, by integrally forming the air duct 4 and the volute 34, the number of connecting parts between the two can be reduced, and the stability of the structure can be improved. Of course, integral forming can also achieve a smooth transition between the air duct 4 and the volute 34, and the airflow is smoother.

[0059] In some possible implementations, there are multiple centrifugal fans 31, and multiple centrifugal fans 31 share a single third drive motor 6. For example... Figure 4 As shown, there are two centrifugal fans 31, spaced apart within the second chamber 12. The two centrifugal fans 31 share a single third drive motor 6. The output shaft of the third drive motor 6 is connected to the impellers 35 of the two centrifugal fans 31 via a transmission shaft 36. Both ends of the transmission shaft 36 are rotatably connected to the inner wall of the second chamber 12 via bearings. The third drive motor 6 is positioned between the two centrifugal fans 31, avoiding the third outlet 15. Thus, by driving the transmission shaft 36 with the third drive motor 6, the two centrifugal fans 31 work synchronously, increasing the total air volume of the air conditioner and satisfying the air supply requirements of either the first or second air supply state. Furthermore, the arrangement of multiple centrifugal fans 31 reduces the load on a single centrifugal fan 31 and extends the service life of the air conditioner.

[0060] It is understood that the above-described structure using centrifugal fan 31 is illustrative. In other embodiments, the fan assembly 3 can also be a mixed-flow fan or other fans. The above-described structure in which two centrifugal fans 31 share a third drive motor 6 is illustrative. In other embodiments, each centrifugal fan 31 can also be configured with a separate third drive motor 6.

[0061] In order to allow air to enter the centrifugal fan 31 quickly, in some embodiments, at least a portion of the second opening 14 and / or at least a portion of the third opening 15 are provided between two adjacent centrifugal fans 31. Figure 3As shown, there are three second openings 14 and three third openings 15. One second opening 14 and one third opening 15 are located between two centrifugal fans 31. Thus, when the air conditioner is in the first air supply state, the arrangement of multiple second openings 14 facilitates air to enter the first chamber 11 from the first opening 13 and enter the second chamber 12 from the multiple second openings 14. The inlet 32 ​​of the centrifugal fan 31 is located on the side of the volute 34, which facilitates air to enter the volute 34 from the inlet 32 ​​of the centrifugal fan 31 and, through the rotation of the impeller 35, drives the air to be discharged into the room from the third connecting port 43. The second opening 14 located between the two centrifugal fans 31 can at least partially reduce the path of air entering the centrifugal fans 31, improve the air supply efficiency, and accelerate the air circulation between the second chamber 12, the first chamber 11, and the outside. Of course, when the air conditioner is in the second air supply state, the multiple third openings 15 are provided to facilitate the air to enter the second chamber 12 from the third openings 15. Among them, one third opening 15 is provided between the two centrifugal fans 31, so that the air can enter the volute 34 from the inlet 32 ​​and, through the rotation of the impeller 35, drive the air to enter the first chamber 11 from the second connecting port 42, and finally be discharged into the room from the first opening 13.

[0062] Of course, it is understood that the structure described above, with a second opening 14 and a third opening 15 located between two adjacent centrifugal fans 31, is illustrative. In other embodiments, the second opening 14 or the third opening 15 may be located separately between the two centrifugal fans 31. Thus, the placement of the second opening 14 or the third opening 15 between the two centrifugal fans 31 can also accelerate airflow between the second chamber 12, the first chamber 11, and the outside.

[0063] Furthermore, in some possible implementations, the inlet 32 ​​of the centrifugal fan 31's volute is located between two adjacent second openings 14. Thus, when the air conditioner is in the first air supply state, the arrangement of multiple second openings 14 facilitates air entering the first chamber 11 from the first opening 13 and entering the second chamber 12 from the multiple second openings 14. The inlet 32 ​​of the centrifugal fan 31 is located on the side of the volute 34. For example, there can be two inlets 32, each located on the side of the volute 34. In this case, the inlet 32 ​​of the centrifugal fan 31's volute 34 is located between two adjacent second openings 14. This facilitates air to quickly enter the volute 34 from the two inlets 32 of the centrifugal fan 31 and, through the rotation of the impeller 35, drive the air to be discharged into the room from the third connecting port 43. By arranging the inlet 32 ​​between the two second openings 14, the path of air entering the centrifugal fan 31 can be partially reduced, improving air supply efficiency and accelerating air circulation between the second chamber 12 and the first chamber 11.

[0064] Of course, in some possible implementations, the inlet 32 ​​of the volute of the centrifugal fan 31 is located between two adjacent third openings 15. Thus, when the air conditioner is in the second air supply state, the arrangement of multiple third openings 15 facilitates air entering the second chamber 12 from the third openings 15. The inlet 32 ​​of the volute 34 of the centrifugal fan 31 is located between two adjacent third openings 15, and there can be two inlets 32, which are respectively arranged on the side of the volute 34. At this time, the air entering from the two third openings 15 can quickly enter the volute 34 from the two inlets 32 of the corresponding centrifugal fan 31, and through the rotation of the impeller 35, drive the air to enter the first chamber 11 from the second connecting port 42, and finally discharge it into the room from the first opening 13. By setting the inlet 32 ​​between the two third openings 15, the path of air entering the centrifugal fan 31 can be partially reduced, the air supply efficiency can be improved, and the air circulation between the second chamber 12 and the outside can be accelerated.

[0065] In some possible implementations, the heat exchanger 2 has a straight or V-shaped cross-section, such as... Figure 4 As shown, the heat exchanger 2 is inclined from the second opening 14 toward the first opening 13. The cross-section of the heat exchanger 2 can be linear, allowing for full contact between the air and the heat exchanger 2, thus improving heat exchange efficiency. Alternatively, a V-shaped cross-section can further increase the contact area between the air and the heat exchanger 2, further improving heat exchange efficiency. In some possible embodiments, the air conditioner also includes a drip tray located below the heat exchanger 2. This drip tray collects condensate, guides it out, and prevents leakage into the fan, thus avoiding electrical faults and ensuring stable operation of the air conditioner. In some possible embodiments, the air conditioner also includes an auxiliary heating element located on the side of the heat exchanger 2 away from the first opening 13. The auxiliary heating element can be a heating wire, which heats the flowing air. This auxiliary heating element supplements the air conditioner's heating capacity in heating mode, especially in the initial stage of heating mode, where the heating wire quickly generates hot air, ensuring effective indoor heating and improving user experience.

[0066] In some possible implementations, the air conditioner is a ducted unit. This ducted unit encompasses all the beneficial effects of the air conditioner described above. Of course, the above implementation of a ducted unit is illustrative; in other implementations, the air conditioner may also be a wall-mounted air conditioner or a floor-standing air conditioner, etc.
