Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0042] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators 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 indicators will also change accordingly.

[0043] Furthermore, if the embodiments of this utility model 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.

[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 utility model proposes an air conditioner 100. The aim is to optimize the structure of the air conditioner 100 so that the air outlet of the air conditioner 100 can be sealed when the air conditioner 100 is in standby mode.

[0047] 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 duct housing 20 is disposed inside the housing 10 and has an air inlet 203 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 to shield the air outlet area outside the air outlet 201. The second shielding member 32 is movable relative to the first shielding member 31.

[0048] The second shielding member 32 has at least a shielding position for shielding the air duct outlet 201 and a first opening position for opening the air duct outlet 201. In the first opening position, the second shielding member 32 is opposite to and spaced apart from the air duct outlet 201.

[0049] In this invention, the air conditioner 100 further includes a heat exchanger 70 and a fan assembly 40. The fan assembly 40 is disposed within the duct housing 20 and guides the air within the duct housing 20 from the duct inlet 203 to the duct outlet 201. The heat exchanger 70 is disposed within the housing 10 and is located between the air inlet 102 and the duct housing 20. When the air conditioner 100 is operating, air enters through the air inlet 102, exchanges heat with the heat exchanger 70, and then enters the duct housing 20. The fan assembly 40 then guides the heat-exchanged air to be blown out from the duct outlet 201. In an embodiment of this invention, the first shielding member 31 can be disposed around the outer periphery of the duct outlet 201 to shield the portion of the air outlet 101 located in the outer periphery of the duct outlet 201. When the air conditioner 100 is in standby mode, the second shielding member 32 can be in a shielding position to shield the duct outlet 201. Thus, the air duct outlet 201 and the air outlet 101 are respectively shielded by the second shield 32 and the first shield 31, so that the air outlet area of ​​the air conditioner 100 can be effectively shielded, preventing dust and foreign objects from entering the interior of the air conditioner 100 from the air outlet area.

[0050] It should be noted that the air conditioner 100 of this utility model can be a whole-type 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 100 is configured as a wall-mounted unit.

[0052] In one embodiment, the air conditioner 100 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] When the air conditioner 100 is discharging air, the second shield 32 is at least in the first open position that opens the air duct outlet 201. When the second shield 32 is in the first open position, the second shield 32 is positioned at a distance from the air duct outlet 201. The air conditioner 100 can dissipate air from the gap between the air duct outlet 201 and the second shield 32, thereby preventing the air conditioner 100 from blowing air directly onto the human body.

[0054] In an embodiment of this utility model, 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.

[0055] The technical solution of this utility model involves providing a movable air duct shell 20 inside the housing 10 to guide the airflow within the housing 10, allowing the air conditioner 100 to discharge air through the air duct outlet 201. A shielding structure 30 is provided on the air duct shell 20. A first shielding member 31 is positioned outside the air duct outlet 201 to shield the air outlet 101 in the outer region of the air duct outlet 201. A second shielding member 32, movable relative to the first shielding member 31, is provided to provide a shielding position for blocking the air duct outlet 201. And at least has a first open position to open the air duct outlet 201, so that when the air conditioner 100 is in standby mode, the air outlet area of ​​the air conditioner 100 can be shielded by the cooperation of the first shield 31 and the second shield 32 to prevent dust and foreign objects from entering the interior of the air conditioner 100. When the air conditioner 100 is in working mode, when the second shield 32 is in the first open position, air can be discharged through the gap formed between the second shield 32 and the casing 10, so that the air outlet of the air conditioner 100 is dispersed in all directions to prevent the air outlet from blowing directly on the human body.

[0056] In addition, in the embodiments of this utility model, the air outlet 101 has at least a first air outlet area and a second air outlet area, and the air duct shell 20 is movably disposed within the housing 10.

[0057] When the duct housing 20 is in the first position, the duct outlet 201 is connected to the first air outlet area, and the first shielding member 31 shields the second air outlet area. When the duct housing 20 is in the second position, the duct outlet 201 is connected to the second air outlet area, and the first shielding member 31 shields the first air outlet area.

[0058] This configuration allows the orientation of the air duct outlet 201 located on the air duct housing 20 to change as the air duct housing 20 moves within the housing 10. When the air duct housing 20 is in different positions within the housing 10, the air duct outlet 201 can have different air outlet directions. When the air conditioner 100 of this invention is configured as a wall-mounted air conditioner 100, with the first air outlet area located near the top of the housing 10 and the second air outlet area located near the bottom of the housing 10, the air conditioner 100 can have both direct airflow functions near the bottom and top of the housing 10. This eliminates the need for additional air guides on the air conditioner 100 to guide airflow, thereby reducing air pressure loss at the air conditioner 100's outlet.

[0059] Furthermore, when the duct housing 20 is located in different positions and connected to different air outlet areas of the air outlet 101, the first shielding member 31 can shield the remaining areas of the air outlet 101. Specifically, in this utility model, when the 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 remaining air outlet positions of the air outlet 101. In this way, when air is discharged through the air outlet 101, only the part of the air outlet 101 that is connected to the duct outlet 201 is exposed for air flow, and the remaining part of the air outlet 101 is shielded by the first shielding member 31. This can prevent air leakage at other positions of the air outlet 101, thereby avoiding uneven mixing of hot and cold air inside the casing 10 due to air leakage, which can cause water vapor in the local area of ​​the air inside the casing 10 to reach saturation and cause condensation. Furthermore, looking at the front of the air conditioner 100, the side with the air outlet 101 has no exposed gaps except for the air duct outlet 201, making the air conditioner more aesthetically pleasing overall.

[0060] The air conditioner 100 of this utility model is equipped with at least a cooling mode and a heating mode. When the air conditioner 100 is configured as a wall-mounted unit, with the first position close to the upper part of the casing 10 and the second position close to the lower part of the casing 10, when the air conditioner 100 operates in cooling mode, the air duct casing 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, and the air conditioner 100 does not need to guide the airflow upward through the air guide plate when discharging air, thereby reducing the pressure loss of the airflow and taking advantage of the fact that cold air is denser and sinks more easily. When the air conditioner 100 is in heating mode, the air duct housing 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 housing 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 released. The pressure loss of the air outlet is small, and the airflow is more likely to flow close to the wall to the ground or directly to the ground. Thus, the characteristics of hot air with low density and easy to rise can be utilized to make hot air cover the indoor space from bottom to top and achieve heating.

[0061] It is understood that this utility model, 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, this utility model 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.

[0062] In this invention, the duct shell 20 and the first shielding member 31 may not be connected; it is sufficient that they can move synchronously. Alternatively, the duct shell 20 and the first shielding member 31 may be connected, so that when the duct shell 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 shell 20 are assembled together; or, the first shielding member 31 and the duct shell 20 are integrally formed. The assembled connection may include snap-fit, riveting, insertion, welding, etc. The first shielding member 31 may be configured as a first shielding plate, and the second shielding member 32 may be configured as a second shielding plate.

[0063] 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 can be set for the duct housing 20. 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, thus shielding the air outlet 101. During the rotation of the duct housing 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. A related configuration method for allowing the duct housing 20 to move between the first and second positions by rotating the duct housing 20 is as follows:

[0064] See Figure 5 , Figure 6 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 and switch between a first position and a second position.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] See Figure 5 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 203, 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 203, 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 203 to the air duct outlet 201, forming an outlet at the air duct outlet 201.

[0069] See Figure 5 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.

[0070] 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.

[0071] In addition, this utility model also provides an additional limiting structure inside 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.

[0072] 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.

[0073] 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.

[0074] Optionally, in one embodiment, when the duct housing 20 is in the first position, the first shield 31 overlaps with the edge of the second air outlet area; and / or

[0075] 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.

[0076] 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.

[0077] 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.

[0078] See Figure 5As 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.

[0079] 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.

[0080] Continue reading Figure 5 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.

[0081] 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.

[0082] 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.

[0083] 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.

[0084] In addition, in this utility model, a retaining edge 311 can be provided on the periphery of the first shielding member 31 to increase the structural strength of the first shielding member 31.

[0085] See Figure 3 As shown, optionally, the first shielding member 31 further includes a retaining edge 311 disposed around the periphery of the first shielding member 31, the retaining edge 311 being disposed on the side of the first shielding member 31 facing the housing 10. The retaining edge 311 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 311. Since the retaining edge 311 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.

[0086] When the duct housing 20 rotates, the blocking structure 30 moves along with it. When the duct housing 20 reaches the designated position, since the second blocking member 32 is movably disposed on the first blocking member 31, the duct outlet 201 can be opened by moving the second blocking member 32, allowing the air conditioner 100 to discharge air through the duct outlet 201. The relevant settings are as follows:

[0087] See Figure 5 , Figure 6 As shown, in one embodiment, the first open position and the blocking position are disposed towards the air duct outlet 201, and the first open position is located on the side of the blocking position away from the air duct housing 20. Specifically, when the second blocking member 32 is in the blocking position, the second blocking member 32 blocks the air duct outlet 201; when the second blocking member 32 is in the first open position, the second blocking member 32 opens the air duct outlet 201.

[0088] In the above embodiment, the blocking position and the first open position face the air duct outlet 201, and the blocking position and the first open position are arranged opposite to each other. This allows the second blocking member 32 to open and block the air duct outlet 201 through linear movement. Of course, in other embodiments, the first open position can also be set on the first blocking member 31 and located away from the air duct outlet 201. When the second blocking member 32 moves between the blocking position and the first open position, the second blocking member 32 slides along the first blocking member 31, realizing the switching of the working position of the second blocking member 32. The relevant settings will not be described in detail here.

[0089] In addition, the second shield 32 also has a second open position. When the second shield 32 is in the second open position, it can form a certain angle with the air duct outlet 201 to guide the air outlet of the air duct shell 20. The relevant settings are as follows: (See reference) Figure 6 , Figure 7 As shown, in one embodiment, the second shielding member 32 also has a second open position for opening the air duct outlet 201. In the second open position, the second shielding member 32 is set at a preset angle relative to the air duct outlet 201 to be suitable for extending the air duct of the air duct shell 20.

[0090] In the above embodiment, when the second blocking member 32 is in the first open position, the second blocking member 32 can move to the second open position by swinging along the first direction. When the air conditioner 100 of this utility model is configured as a wall-mounted unit, the first direction can be the up and down direction. Since the first open position is set towards the air duct outlet 201, the second blocking member 32 can swing along the up and down direction and be guided to the second open position. As an extension of the air duct housing 20 and the air duct 202, it guides the air out of the air duct outlet 201, reduces the air dispersion of the air conditioner, and increases the ground air delivery distance when the air conditioner 100 blows air downwards.

[0091] In the above embodiments of this utility model, the second shielding member 32 can be operated manually or automatically. When the air conditioner 100 is configured as a wall-mounted unit, in order to improve the operation experience of the second shielding member 32, this utility model chooses to operate the second shielding member 32 automatically, and the relevant settings are as follows.

[0092] See Figure 3 , Figure 4 As shown, in one embodiment, the air conditioner further includes a blocking drive member 50 that drives the second blocking member 32 to translate between a blocking position and a first open position, and to drive the second blocking member 32 to swing between the first open position and the second open position.

[0093] With this configuration, the second blocking member 32 can be driven by the blocking drive member 50 to move between the blocking position and the first open position, thereby opening or blocking the air duct outlet 201. When the second blocking member 32 is in the first open position, the second blocking member 32 can be driven by the blocking drive member 50 to swing in the first open position, so that it moves to the second open position, serving as an extension of the air duct 202. Alternatively, the second blocking member 32 can be driven to swing between the first open position and the second open position, so that the second blocking member 32 can swing to other positions that form an angle with the air duct outlet 201, thereby changing the airflow direction at the air duct outlet 201 when air is being discharged from the air duct outlet 201.

[0094] The blocking drive component 50 can be configured as a drive motor structure and an irregular rack structure. The shape of the irregular rack structure can be designed according to the running trajectory of the second blocking component 32. In this way, the second blocking component 32 can be guided by the irregular rack structure to move along a preset running path. The relevant settings are as follows:

[0095] Continue reading Figure 3 , Figure 4 Optionally, the blocking drive component 50 includes a first drive motor 51, a transmission gear 52 and a gear condition 53. The first drive motor 51 is disposed on the first blocking component 31, the gear condition 53 is disposed on the second blocking component 32, and the transmission gear 52 drives the first drive motor 51 and the gear condition 53.

[0096] The tooth condition 53 has a first rack segment 531 and a second rack segment 532. The first rack segment 531 is arranged in a straight line. The first drive motor 51 is used to drive the transmission gear 52 to move along the first rack segment 531, so as to drive the second blocking member 32 to translate between the blocking position and the first open position. The second rack segment 532 is arranged in an arc shape. The first drive motor 51 is used to drive the transmission gear 52 to move along the second rack segment 532, so as to drive the second blocking member 32 to swing between the first open position and the second open position.

[0097] In the above embodiments, both the first rack segment 531 and the second rack segment 532 are provided with continuously distributed tooth grooves, and both the first rack segment 531 and the second rack segment 532 are meshed and matched with the transmission gear 52.

[0098] The first rack segment 531 can be straight, and the second rack segment 532 can be arc-shaped, with the radii of curvature of each part of the second rack segment 532 being equal. With this configuration, when the second blocking member 32 opens or closes the air duct outlet 201, the first drive motor 51 drives the transmission gear 52 to rotate, causing the first rack segment 531, which meshes with the transmission gear 52, to slide along its length, allowing the second blocking member 32 to move from the blocking position of the air duct outlet 201 to the first open position of the air duct outlet 201. When the second blocking member 32 swings from the first open position to the second open position, the first drive motor 51 continues to drive the transmission gear 52 to rotate, causing the second rack segment 532, which meshes with the transmission gear 52, to swing along its arc, thereby causing the second blocking member 32 connected to the rack segment 532 to swing to the second open position, which can act as an extension of the air duct 202, guiding the airflow at the air duct outlet 201.

[0099] Of course, in other embodiments, the radii of curvature of each part of the second rack segment 532 can also be set to be unequal, as long as it can drive the second shield 32 to swing and guide the air flow at the air duct outlet 201.

[0100] To ensure that the transmission gear 52 remains engaged with the gear condition 53 during the process of the first drive motor 51 driving the second blocking member 32, refer to... Figure 4 As shown, optionally, the gear condition 53 is provided with a guide portion 54, which extends from the first rack segment 531 to the second rack segment 532, and the guide portion 54 is used to guide the movement of the transmission gear 52.

[0101] The guide part 54 can be a guide groove formed on the tooth condition 53. The transmission rod of the transmission gear 52 connected to the first drive motor 51 is slidably installed in the guide groove. When the transmission rod of the transmission gear 52 slides along the guide groove, the transmission gear 52 is always in a state of meshing with the tooth groove of the tooth condition 53. This setting can prevent the tooth condition 53 from shifting and being unable to effectively drive the movement of the second blocking member 32.

[0102] Of course, in other embodiments, the guide 54 may also be a track structure mounted on the tooth condition 53. The track structure extends along the direction of the tooth condition 53, and the rotation center of the transmission gear 52 is at least partially located on the track structure and can slide along the track structure. This also allows the transmission gear 52 to always maintain a state of meshing with the tooth groove of the tooth condition 53.

[0103] In the above embodiments, in order to ensure that the second blocking member 32 moves more smoothly and stably, optionally, the blocking driving member 50 is provided in two sets, and the two sets of blocking driving 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.

[0104] In an embodiment of this utility model, when the air conditioner 100 is configured as a wall-mounted unit, the second direction can be left or right. 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 movement.

[0105] See Figure 1 As shown, in one embodiment, the air conditioner 100 further includes an air guide 60, which is disposed inside the air duct housing 20. The air guide 60 is used to swing along a second direction to guide the air flow at the air duct outlet 201, wherein the first direction and the second direction are intersecting.

[0106] In this invention, when the air conditioner 100 is configured as a wall-mounted unit, the second direction can be left-right, and the first direction can be up-down. This configuration allows the air conditioner 100 to adjust its airflow angle in the up-down direction by moving the duct housing 20 between the first and second positions, and by swinging the second blocking member 32 between the first and second open positions. Furthermore, the air conditioner 100 can swing left-right within the duct housing 20 via the air guide member 60, thus adjusting its airflow angle in the left-right direction. This provides the air conditioner 100 with a wider range of airflow angles.

[0107] Continue reading 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.

[0108] 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 left-right direction within the air duct shell 20.

[0109] In this 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 shell 20 is taken as the axis, in order to improve the integration between the second shielding member 32 and the first shielding member 31 when shielding the duct outlet 201, 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:

[0110] Optionally, the fan assembly 40 has a fan wheel, and both the first shielding member 31 and the second shielding member 32 are arc-shaped. The center of the arc of the first shielding member 31 is located on the rotation axis of the fan wheel. When the second shielding member 32 is in the shielding position and the first open position, the center of the arc of the second shielding member 32 is located on the rotation axis of the fan wheel.

[0111] In one embodiment, imperceptible airflow can also be achieved by creating micro-holes 321 on the second shielding member 32. Optionally, the second shielding member 32 has micro-holes 321, and the air conditioner 100 has an imperceptible airflow mode. When the air conditioner 100 is in the imperceptible airflow mode, the second shielding member 32 is in a shielding position, and the air conditioner 100 is used to vent airflow from the micro-holes 321.

[0112] Thus, when the second shielding member 32 shields the air duct outlet 201, the air pressure can be dispersed through the micro-holes 321, reducing the air outlet speed and air flow, making the air outlet more dispersed, and avoiding discomfort caused by the air outlet.

[0113] 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 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 air duct housing 20 can be rotated by adjusting the driving component, placing the air duct housing 20 in a first position. This, in turn, opens the air duct outlet 201 by driving the second blocking component 32, allowing air to exit 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 the driving component, allowing air to exit towards a position near the top of the air conditioner 100. When the air duct housing 20 is in the second position, the second blocking member 32 is driven to move to the first open position or the second open position, opening the air duct outlet 201 and discharging air towards the bottom of the air conditioner 100 through the air duct outlet 201. When the air conditioner 100 is in standby mode, the air 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 driven to move to the blocking position by the blocking drive member 50, blocking the air 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.

[0114] 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.

[0115] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. 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.
