Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and more particularly to a vertical air conditioning indoor unit. Background Technology

[0002] Household air conditioner indoor units are mainly of two types: wall-mounted and floor-standing. In order to facilitate the adjustment of the airflow direction, multiple rotatable air guides are generally installed at the air outlet of the air conditioner indoor unit.

[0003] However, in practice, the air guide vane may get stuck during rotation. Utility Model Content

[0004] This application discloses a vertical air conditioner indoor unit that can reduce the risk of the air guide plate getting stuck during rotation.

[0005] To achieve the above objectives, this application discloses a vertical air conditioner indoor unit, comprising: The housing is provided with a heat exchange air inlet and a heat exchange air outlet. The heat exchange air outlet includes a front air outlet and a side air outlet. The front air outlet is located on the front side of the housing along its depth direction, and the side air outlet is located on one side of the housing along its width direction. The front air outlet is positioned higher than the side air outlet. An indoor heat exchanger is disposed within the casing; A fan is installed inside the housing. The fan drives indoor air to enter the housing through the heat exchange inlet and exchange heat with the indoor heat exchanger, and then discharges it into the room through the heat exchange outlet. A raised rib is provided on the outer surface of the housing and located above the side air outlet. The length direction of the raised rib is parallel to the height direction of the housing. An air guide plate is provided at the side air outlet. The length direction of the air guide plate is parallel to the height direction of the housing. The air guide plate has a first end face and a second end face distributed along its own width direction. The first end face is located outside the second end face. A rotating shaft is disposed between the air guide plate and the rib and extends along the height direction of the housing, so that the air guide plate can rotate relative to the rib around the rotating shaft. Along the width direction of the air guide plate, the first distance between the axis of the rotating shaft and the first end face is less than the second distance between the axis of the rotating shaft and the second end face.

[0006] In this application, the housing is provided with a side air outlet, and the outer surface of the housing is provided with a raised rib. The raised rib is located above the side air outlet. The length direction of the raised rib and the air guide plate are parallel to the height direction of the housing. The air guide plate and the raised rib are correspondingly arranged along the height direction of the housing. A rotating shaft extending along the height direction of the housing is arranged between the raised rib and the air guide plate. The air guide plate can rotate relative to the raised rib around the rotating shaft. Since the rotating shaft is located on the raised rib, during the rotation of the air guide plate, a part of the air guide plate is always arranged opposite to the raised rib along the height direction of the housing. The raised rib will restrict the air guide plate from moving along the height direction of the housing. Therefore, under the restriction of the raised rib, the air guide plate cannot move to a position opposite to the raised rib in the swing direction of the air guide plate. In this way, the raised rib will not restrict the swing of the air guide plate, thus solving the problem of rotation jamming caused by the restriction of the raised rib.

[0007] In addition, the air guide plate has a first end face and a second end face distributed along its own width direction. The first end face is located outside the second end face. Along the width direction of the air guide plate, the first distance between the axis of the rotating shaft and the first end face is smaller than the second distance between the axis of the rotating shaft and the second end face. That is to say, the axis of the rotating shaft is closer to the outside of the air guide plate. This can reduce the swing amplitude of the outside of the air guide plate, reduce the misalignment distance between the outside of the air guide plate and the protruding rib during the swing process, and improve the appearance quality of the vertical air conditioner indoor unit.

[0008] Furthermore, since the ribs are located on the outer surface of the housing and the rotating shaft is located between the air guide plate and the ribs, the first distance between the axis of the rotating shaft and the first end face is less than the second distance between the axis of the rotating shaft and the second end face. Compared to the first distance being greater than the second distance, this application can reduce the length of the air guide plate extending to the outer surface of the housing during the swinging process, thereby reducing the probability of the user accidentally touching the air guide plate, reducing the risk that the air guide plate will be located outside the preset position due to the user's accidental touch, and ensuring that the air guide plate can guide air into the indoor space at a preset angle.

[0009] In one alternative embodiment, the first distance is less than or equal to 10 mm.

[0010] If the first distance is greater than 10mm, the axis of the rotating shaft will be less close to the first end face, the swing amplitude of the outer side of the air guide plate will be less reduced, the misalignment distance between the outer side of the air guide plate and the rib will be less reduced, and the improvement of the appearance quality of the vertical air conditioner indoor unit will be limited.

[0011] Therefore, in this embodiment, setting the first distance to be less than or equal to 10mm can make the axis of the rotating shaft closer to the first end face, thereby reducing the swing amplitude of the outer side of the air guide plate and reducing the misalignment distance between the outer side of the air guide plate and the rib, further improving the appearance and texture of the vertical air conditioner indoor unit.

[0012] In one alternative embodiment, the ratio of the first distance to the second distance is 0.5 to 0.1.

[0013] If the ratio of the first distance to the second distance is less than 0.1, the first distance is small. If the air guide plate has a rotating hole to accommodate the rotating shaft, the thickness of the solid part of the air guide plate between the rotating hole and the first end face will be too small. In some cases, the rotating hole may even penetrate the first end face, thus forming a weak area between the rotating hole and the first end face. During the rotation of the air guide plate, the weak area is prone to plastic deformation and cracking. If the ratio of the first distance to the second distance is greater than 0.5, the first distance is large. The axis of the rotating shaft is less close to the first end face, the degree to which the swing amplitude of the outer side of the air guide plate is reduced is small, and the degree to which the misalignment distance between the outer side of the air guide plate and the rib is reduced is also small. The degree to which the appearance quality of the vertical air conditioner indoor unit is improved is limited.

[0014] Therefore, in this embodiment, the ratio of the first distance to the second distance is controlled between 0.5 and 0.1, which allows the first distance to be within a suitable range. This not only makes the axis of the rotating shaft closer to the first end face, thus reducing the swing amplitude of the outer side of the air guide plate, but also reduces the misalignment distance between the outer side of the air guide plate and the protruding rib, further improving the appearance and texture of the vertical air conditioner indoor unit; it also allows for a larger thickness of the solid part of the air guide plate between the rotating hole and the first end face when the rotating hole is provided on the air guide plate, thereby eliminating the weak area formed between the rotating hole and the first end face and reducing the risk of plastic deformation and cracking of the air guide plate.

[0015] In one optional embodiment, the rib is plate-shaped and has a third end face and a fourth end face distributed along its own width direction, the third end face being located outside the fourth end face; Along the width direction of the rib, the third end face is closer to the axis of the rotating shaft than the fourth end face.

[0016] In this embodiment, the third end face of the rib is located outside the fourth end face. The third end face is closer to the axis of the rotating shaft than the fourth end face. In other words, the axis of the rotating shaft is closer to the third end face of the rib than the fourth end face. This allows the axis of the rotating shaft to be set further outward, thereby further reducing the first distance between the axis of the rotating shaft and the first end face of the air guide plate. This further reduces the swing amplitude of the outer side of the air guide plate, further reduces the misalignment distance between the outer side of the air guide plate and the rib, and further improves the appearance and texture of the vertical air conditioner indoor unit.

[0017] In one optional embodiment, the rib is plate-shaped, and when the air guide plate rotates to a position where its width direction is parallel to the width direction of the rib, the first end face and the end face of the rib away from the shell are located on the same plane.

[0018] In this embodiment, when the air guide plate rotates to a position where its width direction is parallel to the width direction of the rib, the first end face and the end face of the rib facing away from the housing are on the same plane. That is, at this position, the first end face does not protrude beyond the end face of the rib facing away from the housing, and the end face of the rib facing away from the housing does not protrude beyond the first end face. This allows the vertical air conditioner indoor unit to have a better appearance. Furthermore, when the air guide plate rotates to a position where its width direction is parallel to the width direction of the rib, the rib will completely cover the outer side of the air guide plate in the height direction of the housing. Therefore, when the air guide plate remains in this position, the rib can prevent dust and impurities from accumulating on the end face of the air guide plate facing the rib, thus maintaining the cleanliness of the air guide plate.

[0019] And / or, in an alternative embodiment, the thickness of the air guide plate is adapted to the thickness of the rib.

[0020] In this embodiment, the thickness of the air guide plate is matched with the thickness of the rib. Thus, when the air guide plate rotates to a position where its width direction is parallel to the width direction of the rib, the two surfaces of the air guide plate are approximately flush with the two surfaces of the rib, which gives the vertical air conditioner indoor unit a better appearance.

[0021] In one optional embodiment, the housing is provided with heat exchange channels that are respectively connected to the heat exchange inlet and the heat exchange outlet, the fan and the indoor heat exchanger are both located in the heat exchange channels, and the ribs are provided corresponding to the heat exchange channels.

[0022] In this embodiment, the heat exchange channel is used to transport air with a large temperature difference from the indoor air, such as cold air or warm air. Therefore, by setting the ribs corresponding to the heat exchange channel, the heat exchange area between the shell and the indoor air can be increased, thereby further reducing the temperature difference between the shell and the indoor space and further reducing the risk of condensation on the outer surface of the shell.

[0023] In an optional embodiment, the vertical air conditioner indoor unit further includes: A drive assembly is disposed inside the housing and connected to the air guide plate to drive the air guide plate to rotate.

[0024] In this embodiment, the vertical air conditioner indoor unit also includes a drive assembly connected to the air guide plate. The drive assembly can drive the air guide plate to rotate. During the operation of the vertical air conditioner indoor unit, the drive assembly can be used to drive the air guide plate to rotate in order to adjust the angle of the air guide plate, thereby adjusting the airflow direction of the air flowing out from the side air outlet, so as to deliver cold or warm air to different areas of the room and improve the efficiency of cooling or heating.

[0025] In one alternative embodiment, the drive assembly is offset from the side air outlet along the direction through the housing.

[0026] In this embodiment, the drive component and the side air outlet are offset along the direction of the side air outlet penetrating the housing. In other words, the drive component is not exposed through the side air outlet, and the user cannot see the drive component through the side air outlet. This can improve the aesthetics of the vertical air conditioner indoor unit. Furthermore, after the drive component and the side air outlet are offset, the drive component will not block the airflow inside the housing from being discharged from the side air outlet, so that the airflow can be delivered more smoothly and concentratedly. This can not only improve the heat exchange efficiency, but also reduce operating noise and improve the user experience.

[0027] In one optional embodiment, the number of the air guide plate, the rib, and the rotating shaft are all multiple. The multiple air guide plates are distributed at intervals along the depth direction of the housing within the side air outlet, and each air guide plate is rotatably connected to the corresponding rib through the corresponding rotating shaft. The driving component includes: Driver source; A transmission mechanism is connected to the drive source, and the transmission mechanism is respectively connected to each of the air guide plates. The transmission mechanism is configured to drive each of the air guide plates to rotate synchronously under the drive of the drive source.

[0028] In this embodiment, the drive component includes a drive source and a transmission mechanism. The transmission mechanism is connected to the drive source and can drive each air guide plate to move synchronously under the drive of the drive source. In this way, only one drive source is needed to drive multiple air guide plates to rotate, without having to configure a separate drive source for each air guide plate. This can not only reduce the manufacturing cost of the vertical air conditioner indoor unit, but also simplify the control logic of the vertical air conditioner indoor unit and reduce the number of failure points.

[0029] In one optional embodiment, the drive source is a motor, and the transmission mechanism includes: An eccentric block is connected to the output shaft of the motor for transmission. The eccentric block includes: The actuating part is eccentrically positioned relative to the output shaft of the motor. A connecting rod has a strip-shaped hole and a plurality of hinge holes distributed along the length direction of the connecting rod. The actuating part is movably inserted through the strip-shaped hole, and the strip-shaped hole is configured to allow the actuating part to slide in the strip-shaped hole when the motor is rotating. Multiple drive shafts are respectively located on the side of each air guide plate away from the rotating shaft. The axis of each drive shaft is parallel to the height direction of the housing. Each drive shaft is hinged to each of the hinge holes.

[0030] This embodiment uses a single motor to drive the eccentric block, and utilizes the sliding mechanism of the connecting rod's slotted hole to convert rotational motion into linear motion. Then, multiple hinged holes synchronously drive the drive shafts of each air guide plate, achieving completely synchronized rotation of all air guide plates. This design avoids the phase difference problem that may occur with traditional multi-drive sources, ensuring consistent air guide plate movement. Furthermore, the linear-to-rotational motion conversion mechanism of the eccentric block and connecting rod eliminates the need for complex gear sets or timing belts, significantly reducing the size of the transmission mechanism and making it suitable for space-constrained scenarios.

Detailed Implementation

[0034] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0035] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "vertical," "horizontal," "lateral," and "longitudinal" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0037] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0038] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, components, or parts (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, components, or parts. Unless otherwise stated, "a plurality of" means two or more.

[0039] Household air conditioner indoor units are mainly of two types: wall-mounted and floor-standing. To facilitate adjusting the direction of airflow and to close the air outlet when the air conditioner is not in use, the air outlet of the indoor unit is generally equipped with multiple rotatable air guide vanes. However, in practice, the air guide vanes are prone to jamming during rotation.

[0040] Please see Figure 1 The inventors discovered that, in order to improve the aesthetics of the indoor unit of an air conditioner, some vertical indoor units have a raised rib 3 parallel to the air guide plate 1 above the air guide plate 1, and the pivot 2 of the air guide plate 1 is located on the inner side along its own width direction, that is, the pivot 2 of the air guide plate 1 is further away from the outer end face of the air guide plate 1. This will cause the outer side of the air guide plate 1 to swing more widely along its own width direction. The air guide plate 1 will swing to the position where its outer side is misaligned with the raised rib 3, that is, the position where the air guide plate 1 is misaligned with the raised rib 3 along its own length direction. At this time, the raised rib 3 and the outer side of the air guide plate 1 are misaligned in the swing direction of the air guide plate 1, so as to allow the air guide plate 1 to swing back and forth.

[0041] When the indoor unit of the air conditioner is running, the temperature inside the indoor unit is significantly different from the room temperature. The inner side of the air guide plate 1 is closer to the inside of the indoor unit than the outer side. Therefore, the temperature difference between the inner and outer sides of the air guide plate 1 is large. Over time, this will cause the air guide plate 1 to deform. With the long-term wear of the rotating shaft 2, when the air guide plate 1 swings to the point where it is misaligned with the outer side of the rib 3, the outer side of the air guide plate 1 and the rib 3 will be opposite each other in the swing direction of the air guide plate 1. At this time, the rib 3 will interfere with the air guide plate 1, thereby restricting the swing of the air guide plate 1 and causing the air guide plate 1 to be stuck in rotation.

[0042] The vertical air conditioner indoor unit provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0043] like Figures 2 to 8 As shown in the figure, this application discloses a vertical air conditioner indoor unit, including: The housing 100 is provided with a heat exchange air inlet 101 and a heat exchange air outlet 102. The heat exchange air outlet 102 includes a front air outlet 1021 and a side air outlet 1022. The front air outlet 1021 is located on the front side of the housing 100 along its depth direction. Figure 3 (As indicated by the arrow in the middle), the side air outlet 1022 is located on the housing 100 along its own width direction ( Figure 3The front air outlet 1021 is positioned higher than the side air outlet 1022, on one side of the direction indicated by the arrow in the middle. For example, the housing 100 is used to form the exterior surface of the vertical air conditioner indoor unit, and the heat exchange air inlet 101 can also be located on the rear side of the housing 100 along its own depth direction.

[0044] The indoor heat exchanger 210 is located inside the housing 100. The indoor heat exchanger 210 can cool or heat the indoor air to achieve the purpose of regulating the temperature of the indoor air.

[0045] Fan 220 is located inside housing 100. Fan 220 is used to drive indoor air into housing 100 through heat exchange inlet 101 to exchange heat with indoor heat exchanger 210, and then discharge it into the room through heat exchange outlet 102.

[0046] A raised rib 300 is provided on the outer surface of the housing 100 and located above the side air outlet 1022. The length direction of the raised rib 300 is parallel to the height direction of the housing 100. Figure 3 (The direction indicated by the arrow in the middle).

[0047] Specifically, after the front air outlet 1021 is provided on the front side of the housing 100, the strength of the housing 100 is reduced. Therefore, in order to improve the strength of the housing 100, this embodiment arranges the front air outlet 1021 and the side air outlet 1022 in sequence in the height direction, and provides a rib 300 above the side air outlet 1022 to improve the structural strength of the housing 100 and enhance the rigidity and deformation resistance of the housing 100. In addition, after providing the rib 300 on the outer surface of the housing 100, the heat exchange area between the housing 100 and the indoor air can be increased to reduce the temperature difference between the housing 100 and the indoor space and reduce the risk of condensation on the outer surface of the housing 100.

[0048] Air guide plate 400 is located at the side air outlet 1022, and the length direction of air guide plate 400 is ( Figure 4 The direction indicated by the arrow m in the middle is parallel to the height direction of the housing 100, and the air guide plate 400 has a direction along its own width ( Figure 4 The first end face 401 and the second end face 402 are distributed in the direction indicated by the arrow in the middle (n). The first end face 401 is located outside the second end face 402. It should be noted that the first end face 401 being located outside the second end face 402 means that the second end face 402 is closer to the interior of the housing 100 than the first end face 401.

[0049] A rotating shaft 500 is disposed between the air guide plate 400 and the rib 300 and extends along the height direction of the housing 100, so that the air guide plate 400 can rotate relative to the rib 300 around the rotating shaft 500. Along the width direction of the air guide plate 400, the first distance between the axis of the rotating shaft 500 and the first end face 401 is ( Figure 10The dimension shown in L1 is less than the second distance between the axis of the rotating shaft 500 and the second end face 402. Figure 10 (The dimensions shown in L2).

[0050] For example, rotating holes can be provided on both the air guide plate 400 and the rib 300, and the two ends of the rotating shaft 500 can be respectively provided in the rotating holes of the air guide plate 400 and the rotating holes of the rib 300; or, the rotating shaft 500 can be integrally formed with one of the air guide plate 400 and the rib 300, and the other of the air guide plate 400 and the rib 300 can be provided with a rotating hole, and the rotating shaft 500 can be provided in the rotating hole.

[0051] In this application, the housing 100 is provided with a side air outlet 1022, and the outer surface of the housing 100 is provided with a rib 300. The rib 300 is located above the side air outlet 1022. The length directions of the rib 300 and the air guide plate 400 are parallel to the height direction of the housing 100. The air guide plate 400 and the rib 300 are correspondingly arranged along the height direction of the housing 100. A rotating shaft 500 extending along the height direction of the housing 100 is provided between the rib 300 and the air guide plate 400. The air guide plate 400 can rotate relative to the rib 300 around the rotating shaft 500. Because of the rib 300, during the rotation of the air guide plate 400, a portion of the air guide plate 400 is always positioned opposite the rib 300 along the height direction of the housing 100. The rib 300 restricts the air guide plate 400 from moving along the height direction of the housing 100. Therefore, under the restriction of the rib 300, the air guide plate 400 cannot move to a position opposite to the rib 300 in the swing direction of the air guide plate 400. Thus, the rib 300 does not restrict the swing of the air guide plate 400, thereby solving the problem of rotational jamming caused by the restriction of the rib 300.

[0052] In addition, the air guide plate 400 has a first end face 401 and a second end face 402 distributed along its own width direction. The first end face 401 is located outside the second end face 402. Along the width direction of the air guide plate 400, the first distance between the axis of the rotating shaft 500 and the first end face 401 is smaller than the second distance between the axis of the rotating shaft 500 and the second end face 402. That is to say, the axis of the rotating shaft 500 is closer to the outside of the air guide plate 400. This can reduce the swing amplitude of the outside of the air guide plate 400, reduce the misalignment distance between the outside of the air guide plate 400 and the protruding rib 300 during the swing process, and improve the appearance quality of the vertical air conditioner indoor unit.

[0053] Furthermore, since the rib 300 is located on the outer surface of the housing 100 and the rotating shaft 500 is located between the air guide plate 400 and the rib 300, the first distance between the axis of the rotating shaft 500 and the first end face 401 is less than the second distance between the axis of the rotating shaft 500 and the second end face 402. Compared to the first distance being greater than the second distance, this application can reduce the length of the air guide plate 400 extending to the outer surface of the housing 100 during the swinging process, thereby reducing the probability of the user accidentally touching the air guide plate 400, reducing the risk that the air guide plate 400 will be located outside the preset position due to the user's accidental touch, and ensuring that the air guide plate 400 can guide air into the indoor space at a preset angle.

[0054] Please see Figure 10 In one optional embodiment, the first distance is less than or equal to 10 mm. For example, the first distance can be 1.6 mm, 2.0 mm, 3.5 mm, 4.3 mm, 5.8 mm, 6.0 mm, 7.1 mm, 8.6 mm, 9.7 mm, etc., and this application does not limit it.

[0055] If the first distance is greater than 10mm, the axis of the rotating shaft 500 will be less close to the first end face 401, the swing amplitude of the outer side of the air guide plate 400 will be less, the misalignment distance between the outer side of the air guide plate 400 and the rib 300 will be less, and the improvement of the appearance quality of the vertical air conditioner indoor unit will be limited.

[0056] Therefore, in this embodiment, setting the first distance to be less than or equal to 10mm allows the axis of the rotating shaft 500 to be closer to the first end face 401, thereby significantly reducing the swing amplitude of the outer side of the air guide plate 400 and the misalignment distance between the outer side of the air guide plate 400 and the protruding rib 300, further enhancing the appearance and quality of the vertical air conditioner indoor unit. Of course, the first distance can also be greater than 10mm, as long as the first distance is less than the second distance.

[0057] In a further embodiment, the first distance is greater than or equal to 1.5 mm.

[0058] If the air guide plate 400 has a rotating hole, and the first distance is less than 1.5mm, the thickness of the solid portion of the air guide plate 400 between the rotating hole and the first end face 401 will be too small. The rotating hole may even penetrate the first end face 401, creating a weak area between them. During the rotation of the air guide plate 400, the rotating shaft 500 will apply a radial load to the weak area, causing stress concentration and potentially leading to plastic deformation and cracking.

[0059] In this embodiment, the first distance is greater than or equal to 1.5 mm, which allows for a larger thickness of the solid portion of the air guide plate 400 located between the rotating hole and the first end face 401. This eliminates the weak area formed between the rotating hole and the first end face 401, thereby reducing the risk of plastic deformation and cracking of the air guide plate 400. Of course, the first distance can also be less than 1.5 mm, and this application does not impose any limitation on this.

[0060] In one optional embodiment, the ratio of the first distance to the second distance is 0.5 to 0.1. For example, the ratio of the first distance to the second distance can be 0.13, 0.2, 0.31, 0.36, 0.4, or 0.48, and this application does not limit it to these values.

[0061] If the ratio of the first distance to the second distance is less than 0.1, the first distance is small. If the air guide plate 400 has a rotating hole for accommodating the rotating shaft 500, the thickness of the solid part of the air guide plate 400 between the rotating hole and the first end face 401 will be too small. In fact, the rotating hole may even penetrate the first end face 401, thus forming a weak area between the rotating hole and the first end face 401. During the rotation of the air guide plate 400, the weak area is prone to plastic deformation and cracking. If the ratio of the first distance to the second distance is greater than 0.5, the first distance is large. The axis of the rotating shaft 500 is less close to the first end face 401, the swing amplitude of the outer side of the air guide plate 400 is less reduced, and the misalignment distance between the outer side of the air guide plate 400 and the protruding rib 300 is also less reduced. The improvement in the appearance and texture of the vertical air conditioner indoor unit is limited.

[0062] Therefore, in this embodiment, the ratio of the first distance to the second distance is controlled between 0.5 and 0.1, which allows the first distance to be within a suitable range. This not only makes the axis of the rotating shaft 500 closer to the first end face 401, thus reducing the swing amplitude of the outer side of the air guide plate 400, but also reduces the misalignment distance between the outer side of the air guide plate 400 and the protruding rib 300, further improving the appearance and texture of the vertical air conditioner indoor unit; it also allows for a larger thickness of the solid portion of the air guide plate 400 between the rotating hole and the first end face 401 when the air guide plate 400 has a rotating hole, thus eliminating the weak area formed between the rotating hole and the first end face 401, thereby reducing the risk of plastic deformation and cracking of the air guide plate 400.

[0063] Please see Figure 6In one optional embodiment, the rib 300 is plate-shaped and has a third end face 301 and a fourth end face 302 distributed along its width direction. The third end face 301 is located outside the fourth end face 302. Along the width direction of the rib 300, the third end face 301 is closer to the axis of the rotating shaft 500 than the fourth end face 302. That is, along the width direction of the rib 300, the distance between the third end face 301 and the axis of the rotating shaft 500 is less than the distance between the fourth end face 302 and the axis of the rotating shaft 500.

[0064] In this embodiment, the third end face 301 of the rib 300 is located outside the fourth end face 302. The third end face 301 is closer to the axis of the rotating shaft 500 than the fourth end face 302. That is, compared to the fourth end face 302, the axis of the rotating shaft 500 is closer to the third end face 301 of the rib 300. This allows the axis of the rotating shaft 500 to be positioned further outward, thereby further reducing the first distance between the axis of the rotating shaft 500 and the first end face 401 of the air guide plate 400. This further reduces the swing amplitude of the outer side of the air guide plate 400, further reduces the misalignment distance between the outer side of the air guide plate 400 and the rib 300, and further improves the appearance and texture of the vertical air conditioner indoor unit. Of course, along the width direction of the rib 300, the third end face 301 can also be further away from the axis of the rotating shaft 500 than the fourth end face 302.

[0065] Please see Figure 6 In one optional embodiment, the rib 300 is plate-shaped. When the air guide plate 400 rotates to a position where its width direction is parallel to the width direction of the rib 300, the first end face 401 and the end face of the rib 300 facing away from the housing 100 are located on the same plane. It should be noted that when this embodiment is combined with the previous embodiment, the end face of the rib 300 facing away from the housing 100 is the third end face 301 of the rib 300.

[0066] In this embodiment, when the air guide plate 400 rotates to a position where its width direction is parallel to the width direction of the rib 300, the first end face 401 and the end face of the rib 300 facing away from the housing 100 are located on the same plane. That is, at this position, the first end face 401 does not protrude beyond the end face of the rib 300 facing away from the housing 100, and the end face of the rib 300 facing away from the housing 100 does not protrude beyond the first end face 401. This allows the vertical air conditioner indoor unit to have a better appearance. Furthermore, when the air guide plate 400 rotates to a position where its width direction is parallel to the width direction of the rib 300, the rib 300 will completely cover the outer side of the air guide plate 400 in the height direction of the housing 100. Therefore, when the air guide plate 400 remains in this position, the rib 300 can prevent dust and impurities from accumulating on the end face of the air guide plate 400 facing the rib 300, thereby maintaining the cleanliness of the air guide plate 400. Of course, when the air guide plate 400 rotates to a position where its width direction is parallel to the width direction of the rib 300, the first end face 401 may also protrude from the end face of the rib 300 away from the housing 100, or the end face of the rib 300 away from the housing 100 may also protrude from the first end face 401. This application does not limit this.

[0067] Please see Figure 6 In one alternative embodiment, the thickness of the air guide plate 400 is adapted to the thickness of the rib 300, that is, without considering the manufacturing errors of the rib 300 and the air guide plate 400, the thickness of the air guide plate 400 is equal to the thickness of the rib 300.

[0068] In this embodiment, the thickness of the air guide plate 400 is matched with the thickness of the rib 300. Thus, when the air guide plate 400 rotates to a position where its width direction is parallel to the width direction of the rib 300, the two surfaces of the air guide plate 400 are approximately flush with the two surfaces of the rib 300, which gives the vertical air conditioner indoor unit a better appearance. Of course, without considering manufacturing errors of the rib 300 and the air guide plate 400, the thickness of the air guide plate 400 may not be equal to the thickness of the rib 300; this application does not impose any limitation on this.

[0069] Please see Figure 3 and Figure 7 In one optional embodiment, the housing 100 is provided with heat exchange channels 103 that are respectively connected to the heat exchange inlet 101 and the heat exchange outlet 102. The fan 220 and the indoor heat exchanger 210 are both disposed within the heat exchange channels 103, and the ribs 300 are provided corresponding to the heat exchange channels 103. That is, in the direction of extending from the inside to the outside, the ribs 300 are disposed opposite to the heat exchange channels 103. Here, the direction of extending from the inside to the outside is the direction of extending from the inside of the housing 100 to the outside of the housing 100.

[0070] In this embodiment, the heat exchange channel 103 is used to transport air with a large temperature difference from the indoor air, such as cold air or warm air. Therefore, by setting the ribs 300 to correspond to the heat exchange channel 103, the heat exchange area between the shell 100 and the indoor air can be increased, thereby further reducing the temperature difference between the shell 100 and the indoor space, and further reducing the risk of condensation on the outer surface of the shell 100.

[0071] Please see Figure 9 In one optional embodiment, the vertical air conditioner indoor unit further includes: A drive assembly 600 is disposed inside the housing 100 and connected to the air guide plate 400 to drive the air guide plate 400 to rotate.

[0072] In this embodiment, the vertical air conditioner indoor unit also includes a drive assembly 600 connected to the air guide plate 400. The drive assembly 600 can drive the air guide plate 400 to rotate. During the operation of the vertical air conditioner indoor unit, the drive assembly 600 can be used to drive the air guide plate 400 to rotate, thereby adjusting the angle of the air guide plate 400 and adjusting the direction of the air flowing out from the side air outlet 1022, so as to deliver cold or warm air to different areas of the room and improve the efficiency of cooling or heating.

[0073] In some other embodiments, the indoor unit of the vertical air conditioner may not include the drive assembly 600, in which case the air guide plate 400 can be rotated manually.

[0074] In one alternative embodiment, the drive assembly 600 is offset from the side air outlet 1022 along the direction in which the side air outlet 1022 penetrates the housing 100.

[0075] In this embodiment, the drive component 600 and the side air outlet 1022 are offset from each other along the direction in which the side air outlet 1022 penetrates the housing 100. That is, the drive component 600 is not exposed through the side air outlet 1022, and the user cannot observe the drive component 600 through the side air outlet 1022, which improves the aesthetics of the vertical air conditioner indoor unit. Furthermore, after the drive component 600 and the side air outlet 1022 are offset, the drive component 600 will not obstruct the airflow from the housing 100 to be discharged from the side air outlet 1022, allowing the airflow to be delivered more smoothly and concentratedly. This not only improves heat exchange efficiency but also reduces operating noise and enhances the user experience. Of course, the drive component 600 can also be positioned opposite the side air outlet 1022 along the direction in which the side air outlet 1022 penetrates the housing 100; this application does not impose any limitation on this.

[0076] In some embodiments, the drive assembly 600 may include a plurality of drive sources 610, each drive source 610 being connected to each air guide plate 400 to drive each air guide plate 400 to rotate. The drive source 610 here may be a motor or a linear motor.

[0077] Please see Figure 9 In one optional embodiment, the number of air guide plates 400, ribs 300 and rotating shafts 500 are all multiple. Multiple air guide plates 400 are spaced apart in the side air outlet 1022 and spaced apart along the depth direction of the housing 100 in the side air outlet 1022. Each air guide plate 400 is rotatably connected to the corresponding rib 300 through the corresponding rotating shaft 500.

[0078] Driver component 600 includes: A drive source 610 and a transmission mechanism 620 are provided. The transmission mechanism 620 is connected to the drive source 610 and is also connected to each of the air guide plates 400. The transmission mechanism 620 is configured to drive each air guide plate 400 to rotate synchronously under the drive of the drive source 610. For example, the drive source 610 can be a motor, and the transmission mechanism 620 can be a linkage 640 mechanism or a gear mechanism; this application does not limit this.

[0079] In this embodiment, the drive assembly 600 includes a drive source 610 and a transmission mechanism 620. The transmission mechanism 620 is connected to the drive source 610. The transmission mechanism 620 can drive each air guide plate 400 to move synchronously under the drive of the drive source 610. In this way, only one drive source 610 is needed to drive multiple air guide plates 400 to rotate, without having to configure a separate drive source 610 for each air guide plate 400. This can not only reduce the manufacturing cost of the vertical air conditioner indoor unit, but also simplify the control logic of the vertical air conditioner indoor unit and reduce the number of failure points.

[0080] Please see Figures 9 to 11 In one optional embodiment, the drive source 610 is a motor, and the transmission mechanism 620 includes: Eccentric block 630 is connected to the output shaft of the motor for transmission. Eccentric block 630 includes: The actuating part 631 is eccentrically positioned relative to the motor's output shaft. This means the axis of the motor's output shaft is not collinear with the axis of the actuating part 631; however, the axis of the motor's output shaft can be parallel to the axis of the actuating part 631. Specifically, the motor can rotate clockwise and counterclockwise, allowing the air guide plate 400 to oscillate back and forth within a certain angle range.

[0081] The connecting rod 640 has a strip-shaped hole and a plurality of hinge holes distributed along the length direction of the connecting rod 640. The actuating part 631 is movably inserted into the strip-shaped hole, which is configured to allow the actuating part 631 to slide within the strip-shaped hole when the motor is rotating. For example, the length direction of the strip-shaped hole may be perpendicular to the length direction of the connecting rod 640.

[0082] Multiple drive shafts 650 are respectively located on the side of each air guide plate 400 away from the rotating shaft 500. The axis of each drive shaft 650 is parallel to the height direction of the housing 100, and each drive shaft 650 is hinged to each hinge hole.

[0083] Please see Figure 11 The specific motion process in this embodiment is as follows: The driving source 610 is a motor, and the output shaft of the motor is connected to the eccentric block 630. The eccentric block 630 will rotate under the drive of the motor, and the actuating part 631 of the eccentric block 630 will rotate around the axis of the output shaft of the motor. In the process of rotating around the axis of the output shaft of the motor, the actuating part 631 will slide in the slot of the connecting rod 640 and actuate the inner wall of the slot to drive the connecting rod 640 to move. During the movement, the connecting rod 640 will drive the drive shaft 650 to move, so that the drive shaft 650 rotates around the axis of the rotating shaft 500, thereby causing the air guide plate 400 to rotate around the axis of the rotating shaft 500.

[0084] In this embodiment, a single motor drives the eccentric block 630, and the rotational motion is converted into linear motion using the sliding mechanism of the strip hole in the connecting rod 640. Then, multiple hinge holes synchronously drive the drive shafts 650 of each air guide plate 400, achieving completely synchronized rotation of all air guide plates 400. This design avoids the phase difference problem that may occur with traditional multi-drive sources 610, ensuring the consistency of the air guide plate 400's movements. Furthermore, the linear-to-rotational motion conversion mechanism of the eccentric block 630 and the connecting rod 640 does not require complex gear sets or timing belts, significantly reducing the size of the transmission mechanism 620, making it suitable for space-constrained scenarios.

[0085] The foregoing embodiments of this application focus on describing the differences between various embodiments. As long as the different optimization features between embodiments are not contradictory, they can be combined to form better embodiments. For the sake of brevity, these differences will not be elaborated upon here. The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art, under the guidance of this application, can make many modifications without departing from the spirit and scope of the claims, all of which fall within the protection scope of this application.
