[0002] Currently, most wall-mounted air conditioners on the market use a deflector to suppress hot airflow in order to improve heating performance. However, this downward pressure on the deflector leads to airflow pressure loss, resulting in reduced air volume and velocity, which affects heating efficiency. Furthermore, there is often a large gap between the leeward side of the deflector and the air conditioner casing, which can cause air leakage and condensation in the ductwork. Utility Model Content

When the air duct assembly is in the first position, the air duct housing abuts against the second limiting part. When the air duct assembly is in the second position, the air duct housing abuts against the first limiting part.

[0013] In one embodiment, when the duct assembly is in the first position, the shield overlaps with the edge of the second air outlet area; and / or

[0014] When the air duct assembly is in the second position, the shield overlaps with the edge of the first air outlet area.

[0015] In one embodiment, the shielding member is provided with an air outlet duct, which is connected to the air outlet of the duct.

[0016] In one embodiment, a recess is formed on the housing, the recess being located on the side of the housing near the first air outlet area, and when the air duct assembly is in the first position, the side of the shield near the top of the housing is at least partially accommodated in the recess.

The shielding plate has an air outlet, the extension surrounds the outer periphery of the air outlet, and the extension has the air outlet duct.

[0018] In one embodiment, the shielding member further includes a retaining edge disposed on the periphery of the shielding plate, the retaining edge being disposed on the side of the shielding plate facing the housing.

[0019] In one embodiment, the shielding member and the air duct shell are assembled structures; or, the shielding member and the air duct shell are integrally formed structures.

[0020] In one embodiment, the air conditioner further includes a damper movably mounted on the housing, the damper being used to shield or open the air duct outlet.

[0021] In one embodiment, the damper is configured as a guide vane rotatably connected to the housing, the guide vane being used to guide the airflow at the air outlet.

[0046] Currently, most wall-mounted air conditioners on the market use a deflector to suppress hot airflow in order to improve heating efficiency. However, this downward pressure on the deflector leads to airflow pressure loss, resulting in reduced airflow volume and velocity, thus affecting heating performance.

[0047] To avoid airflow loss due to the downward pressure of the air guide plate, some technologies employ a rotating duct as a whole, allowing the heating airflow to be delivered downwards without damage, thereby enhancing the heating effect. However, this method requires adequate clearance to maintain a certain rotation angle, resulting in larger gaps in the air conditioner's appearance and affecting its overall aesthetics. Furthermore, the air duct itself poses risks of air leakage and condensation.

[0048] The above content is only used to assist in understanding the technical solution of the utility model and does not represent an admission that the above content is prior art.

[0049] This utility model proposes an air conditioner. The aim is to optimize the structure of the air conditioner, achieving overall rotation of the air duct while reducing external gaps, ensuring the aesthetic appearance of the air conditioner, and preventing air leakage and condensation in the air duct.

[0050] It should be noted that the air conditioner of this utility model can be a whole-unit air conditioner, a split-type air conditioner, or only include the indoor unit of a split-type air conditioner.

[0051] In one embodiment, the air conditioner is configured as a wall-mounted unit.

[0052] In one embodiment, the air conditioner is configured as a split-type air conditioner including a wall-mounted unit, and the housing 10 is disposed on the wall-mounted unit.

[0053] Please see Figures 1 to 12 In one embodiment of the present invention, the air conditioner 100 includes a housing 10, an air duct assembly 20, and a shielding member 22. The housing 10 is provided with an air inlet 102 and an air outlet 101. The air outlet 101 has at least a first air outlet area and a second air outlet area. The air duct assembly 20 is movably disposed within the housing 10. The air duct assembly 20 includes an air duct shell 21 and a shielding member 22. The air duct shell 21 has an air duct inlet communicating with the air inlet 102 and an air duct outlet 201 communicating with the air outlet 101. The shielding member 22 is disposed outside the air duct outlet 201. The fan assembly 30 is disposed within the housing 10 and is used to drive airflow from the air inlet 102 through the air duct assembly 20 to the air outlet 101. The drive assembly is drivenly connected to the air duct assembly 20 and is used to drive the air duct assembly 20 to switch between a first position and a second position.

[0054] When the air duct assembly 20 is in the first position, the air duct outlet 201 is connected to the first air outlet area, and the shielding member 22 shields the second air outlet area.

[0055] When the air duct assembly 20 is in the second position, the air duct outlet 201 is connected to the second air outlet area, and the shielding member 22 shields the first air outlet area.

[0056] In this utility model, the air conditioner 100 further includes a heat exchanger 50, which is disposed inside the casing 10 and located between the air inlet 102 and the air duct assembly 20. When the air conditioner 100 is working, air enters through the air inlet 102, exchanges heat with the heat exchanger 50, and then enters the air duct assembly 20. The air is then guided by the fan assembly 30 to flow within the air duct assembly 20 and blown out from the air duct outlet 201. In an embodiment of this utility model, the air conditioner 100 can be defined as a wall-mounted unit, wherein the first air outlet area can be located near the top of the air conditioner 100, and the second air outlet area can be located near the bottom of the air conditioner 100. Of course, in other embodiments of this utility model, the air conditioner 100 can also be defined as a vertically mounted air conditioner or a floor-standing unit; in this case, the first air outlet area can be located near one side of the air conditioner 100, and the second air outlet area can be located near the other side of the air conditioner 100.

[0057] The air conditioner 100 of this utility model is provided with at least a cooling mode and a heating mode. When the air conditioner 100 is running in cooling mode, the air duct assembly 20 can be moved to the first position, and the air duct outlet 201 is connected to the first air outlet area. At this time, the air outlet 201 is positioned higher. When the air conditioner 100 is discharging air, it does not need to guide the airflow upward through the air guide plate, thereby reducing the pressure loss of the airflow. It can take advantage of the fact that cold air has a high density and is easier to sink, so that the cold air covers the indoor space from top to bottom to achieve cooling. When the air conditioner 100 is in heating mode, the air duct assembly 20 can be moved to the second position, and the air duct outlet 201 is located at the end of the air outlet 101 near the bottom of the casing 10. At this time, the air outlet is more downward, and the air duct outlet 201 does not need to be pressed down by the air guide plate when hot air is emitted. The pressure loss of the airflow is small, and the airflow is more likely to flow close to the wall to the ground or directly to the ground. Thus, the characteristic of hot air having low density and being easy to rise can be used to make hot air cover the indoor space from bottom to top to achieve heating.

[0058] In addition, in cooling mode and heating mode, the air duct assembly 20 can also be located between the first position and the second position, and the air duct outlet 201 can be located between the position near the top of the housing 10 and the position near the bottom of the housing 10. This utility model does not make specific limitations.

[0059] In this invention, when the air duct assembly 20 moves from the first position to the second position, or from the second position to the first position, the shielding member 22 can always be in a state of shielding the other air outlet positions of the air outlet 101. Thus, when air is discharged through the air outlet 101, only the portion of the air outlet 101 that connects to the air duct outlet 201 is exposed for airflow. The rest of the air outlet 101 is shielded by the shielding member 22, thereby preventing air leakage at other positions of the air outlet 101. This avoids uneven mixing of hot and cold air inside the casing 10 due to air leakage, preventing condensation caused by water vapor saturation in local areas of the air inside the casing 10. Furthermore, viewed from the front of the air conditioner 100 (the side of the air conditioner 100 with the air outlet 101), there are no other exposed gaps except for the air duct outlet 201, making the overall air conditioner more aesthetically pleasing.

[0060] The housing 10 may include a front frame assembly 10a, a chassis assembly 10b, and a panel 10c, which are sequentially assembled to form the housing 10. The chassis assembly 10b is used for the installation and fixation of the air conditioner 100. The front frame assembly 10a serves as the main structure of the housing 10, housing the heat exchanger 50 and the air duct assembly 20. The air outlet 101 of the housing 10 may be located on the panel 10c or on the front frame assembly 10a. The air inlet 102 may be located at the top or front of the front frame assembly 10a; the specific location is not limited.

[0061] In this invention, the duct shell 21 and the shielding member 22 may not be connected, as long as they can move synchronously. Alternatively, the duct shell 21 and the shielding member 22 may be connected, so that when the duct shell 21 is driven to move, it can drive the shielding member 22 to move synchronously. Exemplarily, the shielding member 22 and the duct shell 21 are an assembled structure; or, the shielding member 22 and the duct shell 21 are an integrally formed structure. The assembled structure may include structures formed by snap-fit ​​assembly, threaded connection assembly, welding assembly, etc., and this invention does not specifically limit the type of assembly.

[0062] In this invention, the movement of the duct assembly 20 between the first and second positions can be achieved by rotating the duct assembly 20. For example, a rotation center line can be set for the duct assembly 20. The duct outlet 201, the shielding member 22, the air outlet 101, and the housing 10 are all located on the outer periphery of the air outlet 101, on an outer circle centered on the projection point of the rotation center line. When the duct assembly 20 rotates, the shielding member 22 can slide along with the duct assembly 20 on the air outlet 101 and the housing 10 on the outer periphery of the air outlet 101, thus shielding the air outlet 101. During the rotation of the duct assembly 20, the orientation of the duct outlet 201 also changes, allowing the air conditioner 100 to output air in both the first and second air outlet areas.

[0063] The technical solution of this utility model involves providing a movable air duct assembly 20 within the casing 10 of an air conditioner 100, and providing an air duct outlet 201 on the air duct assembly 20 for air outlet of the air conditioner 100. The air duct assembly 20 is defined within the casing 10 to have a first position and a second position. When the air duct assembly 20 is in the first position, the air duct outlet 201 is located in the first air outlet area of ​​the air outlet 101. When the air duct assembly 20 is in the second position, the air duct outlet 201 is located in the second air outlet area of ​​the air outlet 101. When the air conditioner 100 is configured as a wall-mounted air conditioner, and the first air outlet area... When the first air outlet area is close to the top of the air conditioner 100 and the second air outlet area is close to the bottom of the air conditioner 100, the air conditioner 100 can directly send air upwards and downwards through the air duct outlet 201 without the need for a guide vane. When air is discharged through the first air outlet area, the shielding member 22 can shield the second air outlet area, and when air is discharged through the second air outlet area, the shielding member 22 can shield the first air outlet area, thus shielding the exposed part of the air outlet 101, making the appearance of the air conditioner more aesthetically pleasing, and avoiding the risk of condensation caused by air leakage due to large gaps on the surface of the air conditioner 100.

[0064] See Figure 2 , Figure 3 , Figure 6 As shown, in one embodiment, a guiding air duct 202 is formed inside the air duct housing 21. The input end of the guiding air duct 202 forms the air duct inlet, and the output end of the guiding air duct 202 forms the air duct outlet 201. The guiding air duct 202 is used to guide the airflow inside the housing 10 toward the air duct outlet 201.

[0065] In this embodiment, the duct shell 21 has a duct inlet, which connects to the air inlet 102 of the housing 10. The heat exchanger 50 of this invention can be disposed between the air inlet 102 and the duct inlet. A guiding air duct 202 is formed inside the duct shell 21, running from the duct inlet to the duct outlet 201. When the fan assembly 30 is working, the fan assembly 30 guides the airflow to flow within the guiding air duct 202. The heat-exchanged air flows from the duct inlet to the duct outlet 201, forming an outlet at the duct outlet 201.

[0066] Furthermore, the duct assembly 20 switches between the first and second positions by moving the duct housing 21. The fan assembly 30 does not move within the duct housing 21; it only moves relative to the duct housing 21. The movement of the duct housing 21 within the housing 10 can be achieved by rotating the duct housing 21. When the duct housing 21 rotates within the housing 10, a drive unit can be provided to rotate the duct housing 21, thus enabling the duct assembly 20 to have both the first and second positions. For example:

[0067] Optionally, the air duct assembly 20 is rotatably disposed within the housing 10 about the axis of the fan assembly 30, and the drive assembly is used to drive the air duct assembly 20 to rotate and switch between a first position and a second position.

[0068] The driving component can be configured as a drive motor and a gear set structure. The gear set structure is connected to the drive motor and the air duct housing 21 respectively. Driven by the drive motor, the air duct housing 21 is rotated, enabling the air duct assembly 20 to switch between a first position and a second position, allowing the air duct outlet 201 to change its orientation. Furthermore, when the air duct housing 21 switches positions by being driven to rotate, the shielding member 22 and the portion of the housing 10 with the air outlet 101 are designed as concentric circles in projection. During the movement of the air duct housing 21, the shielding member 22 remains concentric with the portion of the housing 10 with the air outlet 101, with a constant distance between them. This allows for a sufficiently small distance between the shielding member 22 and the housing 10, simplifying the method of shielding the exposed portion of the air outlet 101 during the movement of the air duct housing 21. The installation cost of the air duct assembly 20 and the shielding member 22 is also lower.

[0069] In other embodiments, the driving component can be configured as a separate motor structure to realize the rotation of the air duct housing 21, or the driving component does not need to drive the air duct housing 21 to rotate, but instead drives the air duct housing 21 to move along a preset track, so that the air duct assembly 20 can switch between a first position and a second position. The specific configuration is not limited.

[0070] In other embodiments of this utility model, a driving component may not be provided, and the duct shell 21 may be rotated manually to switch the duct assembly 20 between the first position and the second position. Optionally, the fan assembly 30 may be configured as a cross-flow fan, and the rotation axis of the duct shell 21 may be the axis of the cross-flow fan.

[0071] This configuration allows the rotation axis of the duct housing 21 to coincide with the axis of the cross-flow fan. When the duct housing 21 rotates, the fan assembly 30 can always remain in its original position without moving. This makes the wiring of the fan assembly 30 within the housing 10 simpler, eliminating the need to consider changes in the wiring position of the fan assembly 30 when it moves.

[0072] In addition, when the duct housing 21 rotates inside the housing 10, in order to prevent the duct housing 21 from rotating excessively and causing the duct outlet 201 to be blocked by the housing 10 and unable to ventilate, this utility model also provides a first limiting part 11 and a second limiting part 12 to limit the movement of the duct housing 21 when the duct assembly 20 is in the second position and the first position. The relevant settings are as follows.

[0073] See Figure 6 , Figure 8 , Figure 10 As shown, optionally, the housing 10 is provided with a first limiting part 11 and a second limiting part 12. When the air duct assembly 20 is in the first position, the air duct housing 21 abuts against the second limiting part 12. When the air duct assembly 20 is in the second position, the air duct housing 21 abuts against the first limiting part 11.

[0074] This design prevents the duct housing 21 from rotating excessively, which could cause the duct outlet 201 to be partially blocked by the housing 10, affecting the airflow from the air conditioner 100. It also prevents the duct housing 21 from rotating excessively, which could cause the obstruction 22 to dislodge and expose the air outlet 101.

[0075] See Figure 8 , Figure 10 As shown, in one embodiment, when the air duct assembly 20 is in the first position, the shield 22 overlaps with the edge of the second air outlet area; and / or

[0076] When the air duct assembly 20 is in the second position, the shield 22 overlaps with the edge of the first air outlet area.

[0077] This configuration ensures that the shielding member 22 can connect with the housing 10 regardless of the movement position of the air duct assembly 20, preventing the rest of the air outlet 101 from being exposed. Furthermore, when the air duct assembly 20 is in the second position near the bottom of the housing 10 and the first position near the top of the housing 10, the shielding member 22 can minimize the obstruction of the rest of the air outlet 101, allowing the air duct housing 21 to have a larger swing angle, reaching 30 to 50 degrees. This enables the air outlet 201 to have an air outlet position closer to the bottom and top of the housing 10.

[0078] See Figure 3 , Figure 4 As shown, optionally, the shield 22 is provided with an air outlet duct 221, which is connected to the air outlet 201. In this way, air can be relayed through the air guide duct 202 on the shield 22, so that the airflow blown from the air outlet 201 can be guided out through the air outlet duct 221, avoiding air leakage when air is discharged from the air outlet 201 due to the gap between the shield 22 and the air outlet shell 21.

[0079] See Figure 8 , Figure 10As shown, in one embodiment, a recessed groove 13 is formed on the housing 10. The recessed groove 13 is located on the side of the housing 10 near the first air outlet area. When the air duct assembly 20 is in the first position, the side of the shielding member 22 near the top of the housing 10 is at least partially accommodated in the recessed groove 13.

[0080] The recess 13 can be formed on the panel 10c of the housing 10 and connected to the side of the air outlet 101. When the air duct assembly 20 moves toward the first position, the baffle slides toward the recess 13. When the air duct assembly 20 is in the first position, the portion of the baffle near the top of the housing 10 is accommodated in the recess 13. This enables the baffle to be positioned and moved. Furthermore, when the air duct assembly 20 is in the first position, the baffle can also abut against the wall of the recess 13 on the side away from the air outlet 101, so that the recess 13, together with the second limiting part 12, can limit the movement of the air duct assembly 20.

[0081] For details, please refer to [link / reference]. Figure 8 As shown, in one embodiment, when the baffle is housed in the sink 13, the baffle abuts against the sink wall of the sink 13 on the side away from the air outlet 101.

[0082] In addition, the projection plane can be set with the outer periphery of the baffle plate perpendicular to the center line of the fan assembly 40. The projection of the outer periphery of the housing 10 located at the upper part of the sink 13 is on the same concentric circle. When the baffle plate abuts against the wall of the sink 13, the baffle plate and the housing 10 are connected. From the outside of the air conditioner 100, the integrity is stronger.

[0083] See Figure 4 , Figure 12 As shown, an extension 222 located on the baffle plate is formed on the outer periphery of the air duct outlet 201. The extension 222 is provided on the side of the baffle plate facing the housing 10, and the air outlet duct 221 is provided on the extension 222.

[0084] The extension 222 can be a protrusion located on the outer periphery of the air duct outlet 201 facing the housing 10. The protrusion passes through and opens the air duct 221. The extension 222 can be integrally formed with the baffle plate, which can enhance the structural strength of the baffle plate at the air duct outlet 201 and avoid the problem of the baffle plate's structural strength deteriorating due to the direct opening at the air duct outlet 201. At the same time, the extension 222 can also form the air duct 221 to provide air supply for the air duct 202.

[0085] In addition, in this invention, a retaining edge 223 can be provided on the periphery of the shield to increase the structural strength of the shield.

[0086] See Figure 3 , Figure 4 As shown, optionally, the shielding member 22 further includes a retaining edge 223 disposed on the periphery of the shielding plate, the retaining edge 223 being disposed on the side of the shielding plate facing the housing 10. The retaining edge 223 can be disposed on one side of the shielding plate, on both sides of the shielding plate, or on each side of the shielding plate. Since the retaining edge 223 is disposed on the side of the shielding plate facing the housing 10, this arrangement not only enhances the structural strength of the shielding plate but also reduces the gap between the edge of the shielding plate and the housing 10, thereby reducing air leakage between the housing 10 and the shielding plate.

[0087] See Figure 1 , Figure 2 , Figure 6 As shown, in one embodiment, the air conditioner further includes a damper 40, which is movably mounted on the housing 10 and is used to shield or open the air duct outlet 201.

[0088] Since the rest of the air outlet 101 is blocked by the baffle, when the air conditioner 100 is not in operation, the air duct outlet 201 can be blocked by the movable damper 40, so that the part of the air outlet 101 exposed at the air duct outlet 201 can also be blocked, thereby ensuring the airtightness of the air outlet 101 and improving the dustproof effect of the air conditioner 100; or, the air outlet 101 located on the casing 10 can be directly blocked by the damper 40, which can also achieve the effect of improving the airtightness of the air outlet 101.

[0089] Additionally, when open, the damper 40 can also be used for airflow guidance. Optionally, the damper 40 is configured as an air guide plate rotatably connected to the housing 10, which guides the airflow at the air outlet 101. Thus, when the duct assembly 20 is in the first position and the air conditioner 100 is discharging air, the air guide plate can also guide the airflow towards a position closer to the top of the housing 10, allowing the air conditioner 100 to dissipate air towards a more upward direction; when the duct assembly 20 is in the second position and the air conditioner 100 is discharging air, the air guide plate can also guide the airflow towards a position closer to the bottom of the housing 10, allowing the air conditioner 100 to dissipate air towards a more downward direction. This improves the airflow adjustment angle range of the air conditioner 100.

[0090] In this invention, the air conditioner 100 has at least a cooling mode, a heating mode, and a shutdown mode. With a panel 10c on the casing 10, and the air outlet 101 located below the panel 10c, a first air outlet area positioned close to the panel 10c, and a second air outlet area located below the first air outlet area, when the air conditioner 100 is in cooling mode, the duct casing 21 can be rotated by a drive component, positioning the duct assembly 20 in a first position. The duct outlet 201 is opened via the damper 40 and adjusted to a position tilted upwards towards the air conditioner 100. During cooling, the air conditioner 100 discharges air through the duct outlet 201 towards a position near the top of the air conditioner 100. When the air conditioner 100 is in heating mode... When the air conditioner is in heating mode, the air duct housing 21 can be rotated by the drive component, so that the air duct assembly 20 is in the second position, and the air duct outlet 201 can be opened by the damper 40 and adjusted to a position tilted downwards towards the air conditioner 100. When the air conditioner 100 is heating, air is discharged from the air duct outlet 201 towards a position near the bottom of the air conditioner 100. When the air conditioner is in the off mode, the air duct assembly 20 can be in the first position, the second position, or a position between the first and second positions. At this time, the air duct outlet 201 is closed by the damper 40, so that there are no exposed gaps at the air outlet of the air conditioner, preventing dust and foreign objects from entering the interior of the air conditioner 100 from this position.

[0091] Of course, when the air conditioner 100 is running in cooling mode, the air duct assembly 20 can also be in other positions, such as between the first and second positions. When the air conditioner 100 is running in heating mode, the air duct assembly 20 can also be in other positions, such as between the first and second positions. No specific limitations are made here.

Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
