Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to an air conditioner. Background Technology

[0002] When existing wall-mounted air conditioners change the airflow direction at the air outlet by rotating air guide vanes or air guide grilles, local pressure loss occurs at the air outlet, increasing airflow resistance and reducing the air volume of the air conditioner. Additionally, vortices are formed at the air outlet, increasing the noise of the air conditioner and affecting the user experience. Furthermore, there is air volume loss during heating, and the air outlet is some distance from the wall, which prevents the formation of a strong Coanda effect, resulting in poor hot air landing and a short rolling distance along the ground.

[0003] Meanwhile, due to problems with the installation of the air guide plate, the air conditioner cannot be completely sealed in standby mode, which allows dust to enter the air conditioner, resulting in internal dirt and the growth of bacteria.

[0004] The above content is only used to help understand the technical solution of the invention and does not represent an admission that the above content is prior art. Summary of the Invention

[0005] The main objective of this invention is to provide an air conditioner that prevents dust and foreign objects from entering the air conditioner from the air outlet area.

[0006] To achieve the above objectives, the present invention provides an air conditioner comprising:

[0007] The casing is provided with an air inlet and an air outlet, wherein the air outlet has at least a first air outlet area and a second air outlet area;

[0008] A duct housing, movably disposed within the housing, the duct housing having a duct inlet communicating with the air inlet and a duct outlet communicating with the air outlet; and

[0009] A shielding structure is provided on the air duct shell. The shielding structure includes a first shielding member and a second shielding member. The first shielding member is provided on the outside of the air duct outlet, and the second shielding member is movably provided on the first shielding member. The second shielding member is used to open or block the air duct outlet.

[0010] When the air duct shell is in the first position, the air duct outlet is connected to the first air outlet area, and the first shielding member shields the second air outlet area;

[0011] When the air duct shell is in the second position, the air duct outlet is connected to the second air outlet area, and the first shielding member shields the first air outlet area.

[0012] In one embodiment, the air conditioner further includes an adjustment drive and a fan assembly. The fan assembly is disposed within the duct housing, and the duct housing is rotatably disposed within the housing about the axis of the fan assembly. The adjustment drive is used to drive the duct housing to rotate, so that the duct housing can rotate between a first position and a second position.

[0013] In one embodiment, the housing is provided with rotating bases located on both sides of the duct shell. The duct shell has mounting holes on both sides. The rotating bases are inserted into the mounting holes to limit the radial movement of the duct shell in the fan assembly. The outer periphery of the rotating base is provided with limiting flanges. The limiting flanges abut against the outer edge of the mounting holes to limit the axial movement of the duct shell in the fan assembly.

[0014] In one embodiment, the second shielding member is slidably mounted on the first shielding member, and the air conditioner further includes a shielding drive member that drives the second shielding member to reciprocate along a first direction.

[0015] In one embodiment, the first shielding member has a first end side and a second end side opposite to each other along a first direction. The air duct outlet, the first shielding member, and the second shielding member all extend along a second direction. The first shielding member has an air outlet duct that connects to the air duct outlet. The first shielding member has a first region located between the first end side and the air outlet duct, and a second region located between the second end side and the air outlet duct. When the second shielding member opens the air duct outlet, the second shielding member is located in the first region or the second region, wherein the first direction and the second direction intersect.

[0016] In one embodiment, the blocking drive member is provided in two sets, and the two sets of blocking drive members are respectively disposed on both sides of the second blocking member along the second direction, wherein the first direction and the second direction intersect.

[0017] In one embodiment, the blocking drive includes a first drive motor, a gear set, and a rack. The first drive motor is disposed on the first blocking member, and the rack is disposed on the second blocking member and extends along a first direction. The gear set drives the rack and the first drive motor. The first drive motor is used to drive the rack to slide, thereby causing the second blocking member to slide back and forth along the first direction.

[0018] In one embodiment, the first blocking member is provided with a guide portion extending along the first direction, the guide portion being slidably connected to the second blocking member, and the guide portion being used to guide the sliding of the second blocking member.

[0019] In one embodiment, the wind turbine assembly has a wind turbine, and both the first shield and the second shield are arc-shaped, with the center of the arc of the first shield and the second shield located on the rotation axis of the wind turbine.

[0020] In one embodiment, the air conditioner further includes an air guide, which is disposed within the duct housing and is used to guide the airflow at the duct outlet.

[0021] In one embodiment, the air guide is configured as a louver structure, which is used to oscillate along the length of the air duct outlet to guide the airflow at the air duct outlet.

[0022] In one embodiment, the second shielding member has micropores.

[0023] In one embodiment, the housing has a panel, the air outlet is located on the lower side of the panel, the first air outlet area is disposed close to the panel, and the second air outlet area is located below the first air outlet area;

[0024] And / or, the air conditioner is configured as a wall-mounted unit; or, the air conditioner is configured as a split-type air conditioner including a wall-mounted unit, the housing being disposed in the wall-mounted unit.

[0025] The technical solution of this invention involves setting a movable air duct shell inside the air conditioner casing, and providing an air duct outlet and an air outlet on the air duct shell for air outlet. When the air duct shell is in a first position, the air duct outlet is located in the first air outlet area of ​​the air outlet. When the air duct shell is in a second position, the air duct outlet is located in the second air outlet area of ​​the air outlet. When the air conditioner is configured as a wall-mounted air conditioner, and the first air outlet area is close to the top of the air conditioner and the second air outlet area is close to the bottom of the air conditioner, the air conditioner can directly send air upwards and downwards through the air duct outlet without the need to use a guide vane to guide the airflow. Furthermore, in the standby state of the air conditioner, the second shielding member can shield the air duct outlet, and the first shielding member can shield the remaining area of ​​the air outlet, so that the air outlet area of ​​the air conditioner can be well shielded in the standby state, thereby preventing dust and foreign objects from entering the air conditioner.

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0042] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0043] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or" or "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0044] Existing wall-mounted air conditioner air supply devices generally consist of a cross-flow fan, motor, chassis, front frame, panel, air inlet, evaporator, and air outlet assembly. When the air conditioner is working, the motor drives the cross-flow fan to rotate, and the airflow is delivered through the air inlet, evaporator, cross-flow fan, and air outlet assembly. When the air conditioner changes the air supply direction, it is generally done by using the movement of the air outlet assembly at the air outlet to change the airflow direction, such as rotating air guide vanes or rotating air guide grilles. When a wall-mounted air conditioner changes the air supply direction at the air outlet by rotating air guide vanes or air guide grilles, it will generate local pressure loss at the air outlet, increase airflow resistance, reduce the air volume of the air conditioner, and form vortices at the air outlet, resulting in increased air supply noise and affecting the user experience. Furthermore, there is air volume loss when heating, and the air outlet is some distance from the wall, which prevents the formation of a strong Coanda effect, resulting in poor hot air landing and a short rolling distance along the ground.

[0045] Meanwhile, due to problems with the installation of the air guide plate, the air conditioner cannot be completely sealed in standby mode, which allows dust to enter the air conditioner, resulting in internal dirt and the growth of bacteria.

[0046] This invention proposes an air conditioner. The aim is to optimize the structure of the air conditioner, achieving direct airflow from multiple directions without using a deflector to change the airflow direction, and enabling the air outlet to be sealed off when the air conditioner is in standby mode.

[0047] It should be noted that the air conditioner of the present invention can be a modular air conditioner, a split-type air conditioner, or only include the indoor unit of a split-type air conditioner.

[0048] In one embodiment, the air conditioner is configured as a wall-mounted unit.

[0049] 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.

[0050] Please see Figures 1 to 11 In one embodiment of the present invention, the air conditioner 100 includes a housing 10, a duct housing 20, and a shielding structure 30. 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 duct housing 20 is movably disposed within the housing 10. The duct housing 20 has a first position and a second position located within the housing 10. The duct housing 20 has an air inlet communicating with the air inlet 102 and an air outlet 201 communicating with the air outlet 101. The shielding structure 30 is disposed on the duct housing 20 and includes a first shielding member 31 and a second shielding member 32. The first shielding member 31 is disposed outside the air outlet 201, and the second shielding member 32 is movably disposed on the first shielding member 31. The second shielding member 32 is used to open or block the air outlet 201.

[0051] When the air duct shell 20 is in the first position, the air duct outlet 201 is connected to the first air outlet area, and the first shielding member 31 shields the second air outlet area.

[0052] When the air duct shell 20 is in the second position, the air duct outlet 201 is connected to the second air outlet area, and the first shielding member 31 shields the first air outlet area.

[0053] In this invention, the air conditioner 100 further includes a heat exchanger 70, which is disposed inside the casing 10 and located between the air inlet 102 and the duct casing 20. When the air conditioner 100 is working, air enters through the air inlet 102, exchanges heat with the heat exchanger 70, and then enters the duct casing 20. The fan assembly 40 guides the airflow within the duct casing 20, and the air is blown out from the duct outlet 201. In an embodiment of this invention, 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 invention, the air conditioner 100 can also be defined as a vertically mounted air conditioner 100 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.

[0054] The air conditioner 100 of the present invention is provided with at least a cooling mode and a heating mode. When the air conditioner 100 is configured as a wall-mounted unit and the air conditioner 100 is running in cooling mode, the air duct shell 20 can be moved to a 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, and the air conditioner 100 does not need to guide the airflow upward through the air guide plate when it vents the air, 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 configured as a wall-mounted unit and the air conditioner 100 is running in heating mode, the air duct casing 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.

[0055] It is understood that the present invention, through the movable air duct housing 20, enables the air duct outlet 201 to directly blow air from different positions, thereby avoiding the problem of airflow pressure loss that occurs when the air is guided by the movable air guide plate. Therefore, the present invention is not limited to the specific location of the air duct housing 20 in either cooling or heating mode. In both cooling and heating modes, the air duct housing 20 can also be located between the first and second positions, 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.

[0056] In this invention, when the air duct housing 20 moves from the first position to the second position, or from the second position to the first position, the first shielding member 31 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 first shielding member 31, thereby preventing air leakage at other positions of the air outlet 101. This avoids uneven mixing of hot and cold air inside the housing 10 due to air leakage, preventing condensation caused by water vapor saturation in local areas of the housing 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.

[0057] Furthermore, since the second shield 32 is movably mounted on the first shield 31, when the air conditioner 100 discharges air through the duct housing 20, the second shield 32 can be moved independently to a position away from the duct outlet 201. For example, the second shield 32 can be slidably mounted on the first shield 31, and when the duct housing 20 supplies air through the duct outlet 201, the second shield 32 can be stored between the first shield 31 and the housing 10, thus achieving the concealment of the second shield 32. When the air conditioner 100 is in standby mode and the air duct cover 20 stops blowing air, the second shield 32 can be slid along the first shield 31 to the position facing the air duct outlet 201 to shield the air duct outlet 201. Since the air outlet 101, except for the position facing the air duct outlet 201, is shielded by the first shield 31, in the standby mode of the air conditioner 100, the air outlet of the air conditioner 100 can be completely shielded by the cooperation of the first shield 31 and the second shield 32, which can effectively prevent dust and foreign objects from entering the air conditioner 100 and causing bacteria to grow.

[0058] In addition, micro-holes can be made on the second shield 32. When the second shield 32 blocks the air duct outlet 201, the air conditioner 100 can vent air through the micro-holes on the second shield 32, thereby achieving a windless air supply effect.

[0059] In an embodiment of the present invention, 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 70 and the air duct housing 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.

[0060] In this invention, there may be no connection between the duct housing 20 and the first shielding member 31, as long as they can move synchronously. Alternatively, the duct housing 20 and the first shielding member 31 may be connected, so that when the duct housing 20 is driven to move, it can drive the first shielding member 31 to move synchronously. For example, the first shielding member 31 and the duct housing 20 are assembled together; or, the first shielding member 31 and the duct housing 20 are integrally formed. The assembled connection may include snap-fit, riveting, insertion, welding, etc.

[0061] In this invention, the movement of the duct housing 20 between the first and second positions can be achieved by rotating the duct housing 20. For example, a rotation center line is set for the duct housing 20, and the duct outlet 201, the first shielding member 31, the air outlet 101, and the housing 10 are all located on the outer periphery of the air outlet 101, centered on the outer circle with the projection point of the rotation center line as the center. When the duct housing 20 rotates, the first shielding member 31 can slide along with the duct housing 20 on the air outlet 101 and the housing 10 on the outer periphery of the air outlet 101, thereby shielding the air outlet 101. During the rotation of the duct housing 20, the orientation of the duct outlet 201 also changes, thus enabling the air conditioner 100 to output air in both the first and second air outlet areas.

[0062] The technical solution of the present invention involves providing a movable air duct shell 20 within the casing 10 of the air conditioner 100, and providing an air duct outlet 201 on the air duct shell 20 that communicates with the air outlet 101 for air outlet of the air conditioner 100. When the air duct shell 20 is in a first position, the air duct outlet 201 is located in the first air outlet area of ​​the air outlet 101; when the air duct shell 20 is in a 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 is close to the air conditioner 100... At the top, when 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 using a guide vane to guide the airflow. Furthermore, in the standby state of the air conditioner 100, the second shield 32 can shield the air duct outlet 201, and the first shield 31 can shield the rest of the air outlet 101, so that the air outlet area of ​​the air conditioner 100 can be well shielded in the standby state, thereby preventing dust and foreign objects from entering the air conditioner 100.

[0063] See Figure 2 As shown, in one embodiment, the air conditioner 100 further includes an adjustment drive and a fan assembly 40. The fan assembly 40 is disposed inside the duct housing 20. The duct housing 20 is rotatably disposed inside the housing 10 about the axis of the fan assembly 40. The adjustment drive is used to drive the duct housing 20 to rotate so that the duct housing 20 can rotate between a first position and a second position.

[0064] Thus, when the duct housing 20 switches between the first and second positions, it is achieved by driving the duct housing 20 to rotate via the fan assembly 40. The fan assembly 40 does not move within the duct housing 20, but only moves relative to the duct housing 20. Furthermore, when the duct housing 20 operates within the housing 10 by rotating, the rotation can also be driven by an adjustable drive component to allow the duct housing 20 to have both the first and second positions.

[0065] The adjustment drive component can be configured as a second drive motor and a gear set structure. The gear set structure is connected to the second drive motor and the air duct housing 20 respectively. Driven by the second drive motor, the air duct housing 20 is rotated, allowing it to switch between a first position and a second position, thus changing the orientation of the air duct outlet 201. Furthermore, when the air duct housing 20 switches positions by being driven to rotate, the first blocking member 31 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 20, the first blocking member 31 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 first blocking member 31 and the housing 10, simplifying the method of blocking the exposed portion of the air outlet 101 during the movement of the air duct housing 20. The configuration cost of the air duct housing 20 and the first blocking member 31 is also lower.

[0066] In other embodiments, the adjustment drive can be configured as a separate motor structure to achieve the rotation of the air duct housing 20, or the drive can not drive the air duct housing 20 to rotate, but instead drive the air duct housing 20 to move along a preset track, so that the air duct housing 20 can switch between a first position and a second position. The specific settings are not limited.

[0067] In other embodiments of the present invention, a driving component may not be provided, and the duct housing 20 may be rotated manually to switch between a first position and a second position. Optionally, the fan assembly 40 may be configured as a cross-flow fan, and the rotation axis of the duct housing 20 may be the axis of the cross-flow fan.

[0068] This configuration allows the rotation axis of the duct housing 20 to coincide with the axis of the cross-flow fan. When the duct housing 20 rotates, the fan assembly 40 can always remain in its original position without moving. This makes the wiring of the fan assembly 40 within the housing 10 simpler, eliminating the need to consider changes in the wiring position of the fan assembly 40 when it moves.

[0069] See Figure 7 As shown, in one embodiment, a guiding air duct 202 is formed inside the air duct housing 20. 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. With this configuration, since the heat exchanger 70 can be located between the air inlet 102 and the air duct inlet, when the fan assembly 40 is working, the fan assembly 40 can guide the heat-exchanged airflow to flow within the guiding air duct 202. The heat-exchanged air flows from the air duct inlet to the air duct outlet 201, forming an outlet at the air duct outlet 201.

[0070] See Figure 7 , Figure 8 , Figure 9 As shown, optionally, the housing 10 is provided with a first limiting part 11 and a second limiting part 12. When the air duct housing 20 is in the second position, the air duct housing 20 abuts against the first limiting part 11. When the air duct housing 20 is in the first position, the air duct housing 20 abuts against the second limiting part 12.

[0071] With this configuration, the first limiting part 11 and the second limiting part 12 can limit the rotation of the air duct housing 20, thereby preventing the air duct housing 20 from rotating excessively and causing the air duct outlet 201 to be partially blocked by the housing 10, affecting the air output of the air conditioner 100. At the same time, it can also prevent the air duct housing 20 from rotating excessively and causing the first blocking member 31 to fall out of its original position and expose the air outlet 101.

[0072] In addition, the present invention also provides an additional limiting structure within the housing 10 to limit the movement of the air duct housing 20. (See reference...) Figure 10 , Figure 11 As shown, optionally, in one embodiment, the housing 10 is provided with rotating bases 14 located on both sides of the air duct housing 20. The air duct housing 20 is provided with mounting holes 21 on both sides. The rotating bases 14 are inserted into the mounting holes 21 to limit the movement of the air duct housing 20 in the radial direction of the fan assembly 40. The outer periphery of the rotating bases 14 is provided with limiting flanges 141. The limiting flanges 141 abut against the outer edge of the mounting holes 21 to limit the movement of the air duct housing 20 in the axial direction of the fan assembly 40.

[0073] The rotating base 14 is used to mount the fan assembly 40. When the fan assembly 40 is configured as a cross-flow impeller, the rotating base 14 serves as a rotating seat for the cross-flow impeller. The rotating base 14 is inserted into the duct shell 20 through the mounting hole 21 and assembled with the cross-flow impeller located inside the duct shell 20. With this configuration, when the duct shell 20 moves, the movement of the duct shell 20 in the radial direction of the cross-flow impeller is limited by the cooperation between the rotating base 14 and the mounting hole 21. Furthermore, the limiting flange 141 cooperates with the outer edge of the mounting hole 21 to limit the movement of the duct shell 20 in the axial direction of the cross-flow impeller. The limiting flanges 141 of the two rotating bases 14 can be provided simultaneously inside or outside the duct shell 20; no specific limitation is made here.

[0074] Optionally, at least one set of mounting holes 21 has a notch 22 on its outer periphery. The notch 22 may be elastic, so that the rotating base 14 can be installed into the mounting hole 21 through the notch 22. This facilitates the assembly between the duct housing 20 and the fan assembly 40.

[0075] See Figure 8 , Figure 9 As shown, in one embodiment, when the duct housing 20 is in the first position, the first shielding member 31 overlaps with the edge of the second air outlet area; and / or

[0076] When the air duct housing 20 is in the second position, the first shield 31 overlaps with the edge of the first air outlet area.

[0077] This configuration ensures that the first shielding member 31 can connect with the housing 10 regardless of the movement position of the duct housing 20, preventing the rest of the air outlet 101 from being exposed. Furthermore, when the duct housing 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 first shielding member 31 can minimize the obstruction of the rest of the air outlet 101, allowing the duct housing 20 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 As shown, optionally, the first shielding member 31 is provided with an air outlet duct 312, which is connected to the air outlet 201. In this way, air can be relayed through the air diversion duct 202 on the first shielding member 31, so that the airflow blown from the air outlet 201 can be guided out through the air outlet duct 312, avoiding air leakage when air is blown out of the air outlet 201 due to the gap between the first shielding member 31 and the air outlet shell 20.

[0079] See Figure 8 , Figure 10 As 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 housing 20 is in the first position, the side of the first shielding member 31 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 duct housing 20 moves toward the first position, the first blocking member 31 slides toward the recess 13. When the duct housing 20 is in the first position, the portion of the first blocking member 31 near the top of the housing 10 is accommodated in the recess 13. This allows for the positioning of the first blocking member 31. Furthermore, when the duct housing 20 is in the first position, the first blocking member 31 can 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 first limiting part 11, can limit the movement of the duct housing 20.

[0081] For details, please refer to [link / reference]. Figure 9 As shown, in one embodiment, when the first shielding member 31 is housed in the sink 13, the first shielding member 31 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 perpendicular to the axis of the fan assembly 40. The projection of the outer periphery of the first shielding member 31 can be set on the same concentric circle as the projection of the outer periphery of the housing 10 located at the upper part of the sink 13. When the first shielding member 31 abuts against the wall of the sink 13, the first shielding member 31 connects with the housing 10, and the integrity of the outer surface of the air conditioner 100 is stronger.

[0083] See Figure 3 As shown, an extension 313 located on the outer periphery of the air duct outlet 201 is formed on the first shield 31. The extension 313 is located on the side of the first shield 31 facing the housing 10, and the extension 313 is provided with the air outlet duct 312.

[0084] The extension 313 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 312. The extension 313 can be integrally formed with the first shield 31. This can enhance the structural strength of the first shield 31 at the air duct outlet 201 and avoid the problem of the first shield 31's structural strength deteriorating due to the direct opening at the air duct outlet 201. At the same time, the extension 313 can also form the air duct 312 to provide air supply for the guide air duct 202.

[0085] In addition, in this invention, a retaining edge 314 can be provided on the periphery of the first shielding member 31 to increase the structural strength of the first shielding member 31.

[0086] See Figure 3 , Figure 4 As shown, optionally, the first shielding member 31 further includes a retaining edge 314 disposed around the periphery of the first shielding member 31, the retaining edge 314 being disposed on the side of the first shielding member 31 facing the housing 10. The retaining edge 314 may be disposed on one side of the first shielding member 31, or on both sides of the first shielding member 31, or each side of the first shielding member 31 may have a retaining edge 314. Since the retaining edge 314 is disposed on the side of the first shielding member 31 facing the air duct housing 20, this arrangement not only enhances the structural strength of the first shielding member 31, but also reduces the gap between the edge of the first shielding member 31 and the housing 10, thereby reducing air leakage between the housing 10 and the first shielding member 31.

[0087] See Figure 7 , Figure 8 , Figure 9As shown, the second shielding member 32 is slidably mounted on the first shielding member 31. The air conditioner 100 also includes a shielding drive member 50 that drives the second shielding member 32 to slide back and forth along a first direction.

[0088] In this invention, when the air conditioner is configured as a wall-mounted unit, the first position is near the upper part of the casing 10, and the second position is near the lower part of the casing 10. The first direction can be up and down. When the air duct casing 20 rotates to switch the air supply position, since the first shielding member 31 is set on the air duct casing 20, it can rotate synchronously with the air duct casing 20 to shield the first and second air supply areas of the air outlet 101. Therefore, the first shielding member 31 has sufficient space at the position from the first side end to the air duct outlet 201 and at the position from the second side end to the air duct outlet 201 to accommodate the second shielding member 32. Therefore, the second shielding member 32 can be set to slide along the first direction, so that the third position of the second shielding member 32 has sufficient space on the first shielding member 31, and the second shielding member 32 can be prevented from being exposed when it is stored.

[0089] Furthermore, when the second baffle is slidable via a drive structure, both the first baffle 31 and the second baffle 32 can be driven by independent drive components (the first baffle 31 moves synchronously with the duct housing 20), and their movements do not interfere with each other, thus ensuring that both can accurately perform their respective functions. The baffle drive components 50 can be configured as a set, located on one side of the movement direction of the second baffle 32, while a follower can be provided on the other side of the movement direction of the second baffle 32. When the baffle drive component 50 drives the second baffle 32 to slide on one side, the other side of the second baffle 32 can slide synchronously via the follower.

[0090] Optionally, the first shielding member 31 has a first end side and a second end side opposite to each other along a first direction. The air duct outlet 201, the first shielding member 31, and the second shielding member 32 all extend along a second direction. The first shielding member 31 has an air outlet duct 312 that connects to the air duct outlet 201. The first shielding member 31 has a first region located between the first end side and the air outlet duct 312, and a second region located between the second end side and the air outlet duct 312. When the second shielding member 32 opens the air duct outlet 201, the second shielding member 32 is located in the first region or the second region, wherein the first direction and the second direction intersect.

[0091] It is understandable that when the second shielding member 32 is housed on the first shielding member 31, it can be positioned between the air duct outlet 201 and the first side end, or it can be positioned between the air duct outlet 201 and the second side end; no specific limitation is made here.

[0092] In the above embodiments, to ensure that the second shielding member 32 slides more smoothly and stably, refer to Figure 3 As shown, optionally, the blocking drive member 50 is provided in two sets, and the two sets of blocking drive members 50 are respectively provided on both sides of the second blocking member 32 along the second direction, wherein the first direction and the second direction intersect.

[0093] In an embodiment of the present invention, when the air conditioner 100 is configured as a wall-mounted unit, the second direction can be along the length of the wall-mounted unit. Thus, by synchronously driving both sides of the second blocking member 32 through two sets of blocking drive members 50, the second blocking member 32 moves more smoothly and stably, with higher movement precision, effectively preventing jamming during sliding.

[0094] When setting the blocking drive component 50, the blocking drive component 50 can be set as a cylinder for driving, or set as a rack drive structure or a guide rod drive structure for driving.

[0095] See Figure 3 , Figure 4 As shown, optionally, the blocking drive component 50 includes a first drive motor 51, a gear set 52, and a rack 53. The first drive motor 51 is disposed on the first blocking component 31, and the rack 53 is disposed on the second blocking component 32 and extends along a first direction. The gear set 52 drives the rack 53 and the first drive motor 51. The first drive motor 51 is used to drive the rack 53 to slide, so as to drive the second blocking component 32 to slide back and forth along the first direction.

[0096] The rack 53 can be configured to conform to the surface of the second blocking member 32, thus adapting the rack 53 to the cross-sectional shape of the second blocking member 32. The gear set 52 can have at least one transmission gear. When there is only one transmission gear, it can be connected to the output end of the first drive motor 51, and the transmission gear can mesh with the rack 53 for transmission. Furthermore, the second blocking member 32 can be configured to slide against the surface of the first blocking member 31, thereby enabling the second blocking member 32 to slide along the surface of the first blocking member 31.

[0097] See Figure 4As shown, in one embodiment, the first shielding member 31 is provided with a guide portion 311, which is used to slide the second shielding member 32. The guide portion 311 extends from the first end side toward the second end side.

[0098] In the above embodiment, the guide portion 311 can be configured as a guide rail, which can protrude from the first shielding member 31. Two sets of guide rails can be provided, with the two sets of guide rails arranged along the second direction on both sides of the second shielding member 32. The two sets of guide rails have guide grooves on the side facing the second shielding member 32, which are used to install the edges on both sides of the second shielding member 32. With this configuration, the second shielding member 32 can be limited in the axial direction of the fan assembly 40, preventing the second shielding member 32 from shifting relative to the shielding drive member 50 along the fan assembly 40, thus preventing the second shielding member 32 from being unable to effectively shield the air duct outlet 201 when the air conditioner 100 is in standby mode.

[0099] In an embodiment of the present invention, the duct housing 20 switches between a first position and a second position by rotation. During the rotational switching process, the first blocking member 31 slides along the outer surface of the housing 10. To ensure that the first blocking member 31 does not interfere with the outer surface of the housing 10 during the rotational movement of the duct housing 20, optionally, on the projection plane perpendicular to the axis of the fan assembly 40, the projection of the first blocking member 31 and the projection of the housing 10 on both sides of the air outlet 101 are arranged as concentric circles. This avoids interference between the housing 10 and the first blocking member 31 during the rotational movement of the duct housing 20. In addition, when driving the duct housing 20 to rotate, to avoid interference between the fan assembly 40 disposed inside the duct housing 20 and the duct housing 20, optionally, on the projection plane perpendicular to the axis of the fan assembly 40, the rotation center of the duct housing 20 is the axis of the fan assembly 40. Furthermore, when the cross-section of the first shielding member 31 is an arc and the rotation center of the duct housing 20 is taken as the axis, in order to make the sliding of the second shielding member 32 on the first shielding member 31 smoother, the second shielding member 32 can also be set as an arc shape, and on the projection plane perpendicular to the axis of the fan assembly 40, the projection of the second shielding member 32 and the projection of the first shielding member 31 are also set as concentric circles. The setting method is as follows:

[0100] Optionally, the wind turbine assembly 40 has a wind turbine, and both the first shield and the second shield are arc-shaped, with the arc centers of the first shield and the second shield located on the rotation axis of the wind turbine.

[0101] See Figure 1 As shown, in one embodiment, the air guide 60 is configured as a louver structure, which is used to swing along the length direction of the air duct outlet 201 to guide the airflow at the air duct outlet 201.

[0102] In the above embodiments, the air guide 60 can be configured as multiple louvers arranged at intervals and a louver drive component. The louver drive component is used to drive the multiple louvers arranged at intervals to swing synchronously, so as to guide the direction of the air flowing out of the air duct outlet 201. The louvers can be arranged at intervals in the air duct shell 20 in the vertical direction or in the horizontal direction.

[0103] In this invention, when the air conditioner 100 is configured as a wall-mounted unit, the duct housing 20 rotates between a first position and a second position, enabling the air conditioner 100 to perform vertical airflow sweeping. To enable the air conditioner 100 to adjust airflow in the left-right direction, the louver structure is configured as louvers spaced along the length of the duct outlet 201, which swing between the two sides of the duct outlet 201 to guide airflow at the duct outlet 201. This configuration allows the air conditioner 100 to adjust its airflow position in the left-right direction during airflow, thus providing a wider airflow range.

[0104] In this invention, the air conditioner 100 has at least a cooling mode, a heating mode, and a standby mode. With a panel 10c on the casing 10, and an 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 air duct housing 20 can be rotated by adjusting the driving component to a first position, allowing air to exit through the air duct outlet 201 towards a position near the top of the air conditioner 100; when the air conditioner 100 is in heating mode, the air duct housing 20 can be rotated by adjusting the driving component to a first position, allowing air to exit through the air duct outlet 201 towards a position near the top of the air conditioner 100; when the air conditioner 100 is in heating mode, the air duct housing 20 can be rotated by adjusting the driving component to a first position, allowing air to exit through the air duct outlet 201 towards a position near the top of the air conditioner 100. The duct housing 20 rotates, placing it in the second position, and air is discharged through the duct outlet 201 towards the bottom of the air conditioner 100. When the air conditioner 100 is in standby mode, the duct housing 20 can be in the first position, the second position, or a position between the first and second positions. At this time, the second blocking member 32 is moved by the blocking drive member 50 to block the duct outlet 201, so that there are no exposed gaps at the air outlet of the air conditioner 100, preventing dust and foreign objects from entering the interior of the air conditioner 100 from this position.

[0105] Of course, when the air conditioner 100 is running in cooling mode, the duct casing 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 duct casing 20 can also be in other positions, such as between the first and second positions. No specific limitation is made here.
