[0037] The purpose, features and advantages of the present invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments. DETAILED DESCRIPTION

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0039] It should be noted that the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0040] The present invention provides a floor-standing air-conditioning indoor unit.

[0041] In the embodiment of the present invention, Figures 1 to 7 As shown, the floor-standing air-conditioning indoor unit includes: a shell 10, which is provided with a first air outlet 11; a damper 20, which can be movably mounted on the shell 10 to open or close the first air outlet 11, and the damper 20 has a closed position for closing the first air outlet 11, an open position for opening the first air outlet 11 from the closed position, and a close position for being close to the shell 10 from the open position.

[0042] In this embodiment, the shell 10 extends in the vertical direction as a whole, and the cross-sectional shape of the shell 10 can be circular, elliptical, rectangular, etc., which can be selected according to actual use requirements and is not specifically limited here. The shape of the first air outlet 11 can be a long strip, rectangular, elliptical, etc. In order to increase the air supply volume and air supply range, the first air outlet 11 can be a long strip extending up and down. The shell 10 is also provided with an air duct and an air inlet. Of course, the shape of the air inlet can also be a long strip, rectangular, elliptical, etc. A heat exchanger and a fan are provided in the air duct. The fan is used to drive air from the air inlet into the air duct and exchange heat with the heat exchanger, and then blown out from the first air outlet 11.

[0043] The damper 20 can move in the form of rotation or sliding, and there is no restriction here. It is sufficient that the damper 20 can open or close the first air outlet 11. When the air conditioner is turned off, the damper 20 closes the first air outlet 11 to maintain the consistency of the appearance of the floor-standing air conditioner indoor unit. The damper 20 can move between the closed position, the open position, and the close position. In the close position, the plate surface of the damper 20 is close to the shell 10 to reduce the gap between the damper 20 and the shell 10, thereby reducing the horizontal space occupied by the shell 10 after the damper 20 is opened. It can be understood that on the movement trajectory of the damper 20, the open position is located between the closed position and the close position; when the damper 20 closes the first air outlet 11, it first moves from the close position to the open position, and then from the open position to the closed position, so as to simplify the movement trajectory of the damper 20. For example, the damper 20 can be movable by rotation, and the rotation axis is provided on a vertical side of the damper 20. When the damper 20 is rotated to the open position, the first air outlet 11 is fully opened. At this time, the damper 20 can continue to rotate from the open position until its outer surface is close to the shell 10 to reduce the gap between the damper 20 and the shell 10.

[0044] The floor-standing air-conditioning indoor unit of the present invention enables the damper 20 to continue to move to a close position after opening the first air outlet 11, so that the damper 20 is close to the shell 10, thereby reducing the gap between the damper 20 and the shell 10 after opening the first air outlet 11, thereby reducing the lateral size of the shell 10, thereby reducing the lateral space occupied by the air-conditioning indoor unit in operation.

[0045] 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 position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0046] In addition, if the embodiments of the present invention include descriptions of "first," "second," etc., such 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. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one of such features.

[0047] In one embodiment, if Figures 1 to 3 As shown, the damper 20 is slidably mounted on the housing 10 and can slide in the direction from the closed position to the open position, and from the open position to the close position. In this embodiment, the damper 20 can slide in the transverse direction to slide from the closed position to the open position, and then slide circumferentially from the open position to the close position. The sliding trajectory of the damper 20 can be an arc or a straight line, which is not limited here. During the sliding process, the inner surface of the damper 20 always faces the housing 10, and in the close position, the inner surface of the damper 20 is also close to the housing 10. In this way, the activity trajectory of the damper 20 can be simplified to reduce the activity range of the damper 20.

[0048] Specifically, the curvature of the sliding trajectory of the damper 20 when it slides from the closed position to the open position is smaller than the curvature of the sliding trajectory when it slides from the open position to the close position. In this embodiment, the sliding trajectory of the damper 20 when it slides from the closed position to the open position, as well as the trajectory of the slide rail 333 when it slides from the open position to the close position, can be arcs, so as to effectively avoid the housing 10 during the sliding process and ensure smooth sliding. It can be understood that the sliding trajectory of the damper 20 is convex relative to the housing 10, while the curvature of the sliding trajectory when it slides from the open position to the close position is greater, which enables the damper 20 to slide more smoothly towards the close position without changing the activity mode and drive mode after opening the first air outlet 11, so that the two sliding trajectories of the damper 20 can be more naturally and smoothly connected, thereby improving the sliding stability of the damper 20. By controlling the curvature of the movement trajectory to control the change in the movement direction of the damper 20 from the closed position to the open position and from the open position to the close position, the turning process of the damper 20 can be made more stable and smooth, and the movement range of the damper 20 can also be reduced to improve the stability of the movement process.

[0049] In practical applications, such as Figure 4 and Figure 5As shown, the floor-standing air conditioner indoor unit further includes a drive device 30, comprising a transmission assembly and a driver 31 for driving the transmission assembly. The transmission assembly is connected to the damper 20 via a rotating arm 32 to drive the damper 20 to slide. In this embodiment, the driver 31 drives the transmission assembly to move, thereby moving the rotating arm 32, thereby driving the damper 20 to slide synchronously, thereby achieving automatic sliding of the damper 20. The number of drive devices 30 can be two, wherein the two rotating arms 32 are respectively connected to the upper and lower ends of the damper 20 to increase the driving force of the damper 20 and ensure the stability of the sliding of the damper 20.

[0050] In one embodiment, if Figure 5 When the cam 33 is in the unlocking state, the locking cam 331 is unlocked and the locking cam 332 is unlocked, so that the cam 33 can be unlocked and the locking cam 332 can be unlocked. The driver 31 drives the slide bar 35 , and the rotating arm 32 is connected to the sliding plate 34 .

[0051] In this embodiment, the slide bar 35 slides within the mounting box 33. The sliding shaft 351 cooperates with the sliding plate 34, driving the sliding plate 34 to slide along the slide groove 331. The limiting groove 341 provided on the sliding plate 34 slidably cooperates with the limiting shaft 332 protruding from the mounting box 33. The limiting groove 341 defines the movement trajectory of the sliding plate 34. Because the extension curvature of the sliding section 342 is the same as that of the slide groove 331, when the sliding section 342 cooperates with the limiting shaft 332, the sliding trajectory of the sliding plate 34 and the extension trajectory of the slide groove 331 are the same. In other words, the sliding trajectory of the pivot arm 32 and the extension trajectory of the slide groove 331 are the same. At this point, the pivot arm 32 can drive the damper 20 to slide to the open position. When the damper 20 slides to the open position, the limiting shaft 332 is about to enter the rotating section 343 from the sliding section 342. Because the extension curvature of the rotating section 343 is greater than the extension curvature of the sliding groove 331, and the sliding plate 34 is rotatably engaged with the sliding shaft 351, the sliding plate 34 can rotate relative to the mounting box 33 about the sliding shaft 351. The rotational amplitude is the curvature of the rotating section 343 of the limiting groove 341, or the curvature of the rotating section 343, and the rotational radius is the distance between the sliding shaft 351 and the limiting shaft 332. The rotation of the sliding plate 34 drives the rotating arm 32 to rotate, thereby driving the damper 20 from the open position to the close position, thereby changing the curvature of the sliding trajectory of the damper 20 during the sliding process.

[0052] Specifically, if Figure 5 As shown, the slide bar 35 is an arc-shaped slide bar 35, and the slide groove 331 and the stop groove 341 all extend in an arc. In this embodiment, the slide bar 35, the slide groove 331, and the sliding section 342 of the stop groove 341 have the same curvature. This allows the sliding plate 34 to slide along an arc, thereby driving the damper 20 to slide along the arc and avoid the housing 10 during the sliding process. In addition, the inner wall of the mounting box 33 is provided with a slide rail 333, and the slide bar 35 slidably engages with the slide rail 333. This reduces the contact area between the slide bar 35 and the inner wall of the mounting box 33, thereby reducing the frictional resistance encountered by the slide bar 35 and improving driving efficiency.

[0053] In practical applications, such as Figure 5 As shown, the slide bar 35 is configured as a rack, and the transmission assembly further includes a gear 36 disposed within the mounting box 33 and meshing with the rack. The driver 31 drives the gear 36 to rotate. In this embodiment, the driver 31 is disposed outside the mounting box 33 and fixed to a side of the mounting box 33 facing away from the sliding block to avoid obstructing the movement of the sliding block. The drive shaft of the driver 31 extends into the mounting box 33 and engages with the gear 36 to rotate, thereby driving the slide bar 35 to slide. This makes the internal structure of the drive device 30 more compact and stable.

[0054] In one embodiment, if Figure 3 As shown, the housing 10 includes a front panel, and the outlet surface of the first air outlet 11 is arranged at a convex angle with the front panel. The damper 20 can slide rearward to the open position. In this embodiment, the front panel is located on the front side of the housing 10, and the first air outlet 11 is adjacent to the front panel and extends obliquely rearward relative to the front panel, so that the outlet surface of the first air outlet 11 is arranged at an obtuse convex angle with the front panel. The damper 20 can move rearward to the open position and further approach the side of the housing 10 to fold and hide the damper 20.

[0055] Specifically, if Figures 1 to 3 As shown, there are two first air outlets 11, one on each side of the front panel in a lateral direction, and each of the first air outlets 11 is provided with a damper 20. In this embodiment, both dampers 20 can be moved to an open position away from the front panel and further moved to a close position, respectively, to the sides of the housing 10. This increases the air outlet area of ​​the air conditioner indoor unit while reducing the space occupied by the dampers 20 when the air conditioner indoor unit is open.

[0056] In practical applications, such as Figure 2 As shown, the front panel defines a second air outlet, and the floor-standing air conditioner indoor unit further includes a swirl module 40 disposed at the second air outlet. In this embodiment, the second air outlet can be in the shape of a strip, rectangle, or oval, and the overall shape of the swirl module 40 matches the shape of the second air outlet. The swirl module 40 is configured to allow airflow to pass through and diffuse the airflow passing through it. In other words, after passing through the swirl module 40, the airflow changes its original flow direction and can flow in different directions, thereby achieving diffused wind flow and achieving a breeze-like or windless airflow. The swirl module 40 can include a swirl impeller 42 or a wind dispersal grille, etc., as long as it can diffuse the airflow passing through it.

[0057] In one embodiment, if Figure 6 As shown, the swirl module 40 includes a mounting plate 41 and a swirl wind wheel 42. The mounting plate 41 is provided with a mounting through hole 411, and the swirl wind wheel 42 is correspondingly mounted at the mounting through hole 411. In this embodiment, the swirl wind wheel 42 can be fixedly mounted at the mounting through hole 411, or can be rotatably mounted at the mounting through hole 411. For example, the swirl wind wheel 42 can be an axial flow wind wheel, and the blades of the swirl wind wheel 42 are curved, or are set at an angle to the air inlet direction, so that the air flow passing through the swirl wind wheel 42 forms a swirl, or the air inlet direction is inconsistent with the air outlet direction. In this way, the outgoing air flow can be effectively broken up and stirred, making the outgoing air softer, and with less wind resistance and wind loss, so as to effectively increase the wind-free air volume.

[0058] Specifically, if Figure 6As shown, the swirl impeller 42 includes a stationary impeller 421 and a rotating impeller 422. The stationary impeller 421 is fixedly connected to the mounting hole 411, and the rotating impeller 422 is rotatably mounted to the mounting hole 411, so that the blades of the rotating impeller 422 and the blades of the stationary impeller 421 are stacked or staggered with each other in the wind direction of the mounting hole 411. In this embodiment, to ensure that the airflow blown out of the mounting hole 411 is dispersed by the stationary impeller 421 and the rotating impeller 422, the mounting hole 411 can be circular and adapted to the dimensions of the stationary impeller 421 and the rotating impeller 422. The stationary impeller 421 can be integrally formed with the mounting plate 41, or it can be fixed to the mounting plate 41 by welding, bonding, crimping, or other methods. The rotation of the impeller 422 can be driven by a driving motor, or by providing a rolling bearing or other structure so that the impeller 422 can automatically rotate under the drive of the airflow.

[0059] It should be noted that the static impeller 421 and the rotating impeller 422 are arranged in sequence in the wind direction of the mounting through hole 411. The mounting through hole 411 plays a role in dredging and guiding the airflow. The number and size of the blades of the static impeller 421 can be the same as or different from the number and size of the blades of the rotating impeller 422. Through the rotation of the rotating impeller 422, on the one hand, the airflow is driven to blow out from the mounting through hole 411, reducing wind resistance and wind loss, effectively increasing the air volume, and flexibly controlling the strength of the airflow. On the other hand, the blades of the rotating impeller 422 and the static impeller 421 can be overlapped or misaligned with each other, so that the airflow passing through the mounting through hole 411 is continuously cut, broken up, diverted and stirred by the static impeller 421 and the rotating impeller 422, so that the airflow is softer, the windless effect is greatly improved, and the divergence direction of the airflow is controllable and adjustable.

[0060] In practical applications, such as Figure 1 and Figure 2 As shown, a ventilation net 60 is installed on the air outlet side of the swirl module 40. In this embodiment, the ventilation net 60 can be a rigid net, such as wire mesh, or a flexible net, such as mesh cloth. This is not a limitation, as long as it has mesh openings. After the airflow passes through the swirl module 40 and is dispersed and expanded, it can be further dispersed and expanded by the ventilation net 60 before being blown out, further enhancing the windless effect. The ventilation net 60 is integrally formed with the housing 10; alternatively, the ventilation net 60 can be removably attached to the housing 10.

[0061] In one embodiment, if Figure 7As shown, the shell 10 includes an upper shell and a lower shell, and the first air outlet 11, the first air duct, the second air outlet and the second air duct are all arranged in the upper shell; the lower shell is provided with a fresh air inlet 12 and a fresh air outlet 13, and the fresh air outlet 13 is located below the second air outlet. The floor-standing air-conditioning indoor unit also includes a fresh air module 50 arranged in the lower shell, and the fresh air module 50 has a fresh air duct 51, and the air inlet end of the fresh air duct 51 is connected to the fresh air inlet 12, and the air outlet end of the fresh air duct 51 is connected to the fresh air outlet 13.

[0062] In this embodiment, the fresh air inlet 12 is connected to the outdoor air. Fresh air enters the fresh air duct 51 through the fresh air inlet 12 and is then blown out of the fresh air outlet 13, thereby introducing the outdoor fresh air into the room. The fresh air outlet 13 is located below the second air outlet, that is, below the swirl module 40. This allows the air outlet direction of the fresh air outlet 13 to be consistent with the air outlet direction of the second air outlet, thereby increasing the air volume discharged from the front of the floor-standing air conditioner indoor unit.

[0063] Specifically, if Figure 7 As shown, a fresh air fan 52 and a switching baffle 53 are provided in the fresh air duct 51. The switching baffle 53 has a first switching position and a second switching position. When the switching baffle 53 is in the first switching position, the air inlet side of the fresh air fan 52 is connected to the fresh air inlet 12, and the air outlet side is connected to the fresh air outlet 13; when the switching baffle 53 is in the second switching position, the air outlet side of the fresh air fan 52 is connected to the fresh air inlet 12.

[0064] In this embodiment, the fresh air fan 52 is used to drive the air flow. When the switch baffle 53 is in the first switching position, the fresh air fan 52 operates to achieve the normal introduction of fresh air. When the switch baffle 53 is in the second switching position, the fresh air fan 52 operates. Since the air outlet side of the fresh air fan 52 is connected to the fresh air inlet 12, the air flow in the fresh air duct 51 can be reversed and discharged to the fresh air inlet 12, thereby achieving the effect of refreshing the indoor air.

[0065] The present invention further provides an air conditioner comprising an outdoor unit and a floor-standing indoor unit. The specific structure of the floor-standing indoor unit is similar to that of the aforementioned embodiments. Since the present air conditioner utilizes all of the technical solutions of all of the aforementioned embodiments, it possesses at least all of the beneficial effects of the technical solutions of the aforementioned embodiments, which will not be further detailed here.

All equivalent structural transformations made using the contents of the present description and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present invention.
