Description

Technical Field

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

[0002] In air conditioners, louvers are typically installed at the air outlet to change the direction of airflow and expand the airflow range. In related technologies, the louvers are installed on the lower side wall of the air outlet. Since most of the air outlet faces downwards or tends to face downwards, the louvers can easily obstruct the direction of airflow, affecting the airflow range and airflow effect. Utility Model Content

[0003] The main purpose of this utility model is to propose an air conditioner that aims to reduce the obstruction of airflow to the air outlet by the louvers, thereby ensuring the airflow range and airflow effect.

[0004] To achieve the above objectives, the air conditioner proposed in this utility model includes: The housing has an air outlet, the length direction of which is configured as a first direction, and a mounting part is provided on the upper side of the air outlet; A louver assembly comprising a plurality of louvers spaced apart along the first direction, the louvers being rotatably suspended from the mounting portion via a pivot and positioned opposite to the air outlet.

[0005] In one embodiment, the mounting portion protrudes forward relative to the upper edge of the air outlet.

[0006] In one embodiment, the housing further includes an air outlet wall with the air outlet provided thereon, the air outlet wall being set at an angle to the mounting portion to form a wide air outlet that extends through the housing in the first direction.

[0007] In one embodiment, the housing further includes a front panel located on the front side of the mounting portion, and the pivot is disposed adjacent to the front panel.

[0008] In one embodiment, the distance from the pivot to the front panel is L, satisfying: .

[0009] In one embodiment, the louver includes a front side away from the air outlet, and the pivot is disposed adjacent to the front side.

[0010] In one embodiment, the louver further includes a rear side adjacent to the air outlet, the distance from the pivot to the rear side is H1, and the distance from the pivot to the front side is H2, satisfying: .

[0011] In one embodiment, the housing includes a chassis on the side opposite to the air outlet, the louvers include a front side away from the air outlet, the louvers are oscillating at least in the first direction, and when the angle between the louvers and the air outlet direction is greater than 50°, on the projection surface of the chassis, the front side of the louvers on the side is located outside the air outlet.

[0012] In one embodiment, the louver further includes a rear side adjacent to the air outlet. On the projection surface of the chassis, when the front side coincides with the side of the air outlet, the front side of the louver and the rear side of the adjacent louver at least partially coincide.

[0013] In one embodiment, the air conditioner is configured as a wall-mounted air conditioner.

[0014] The technical solution of this utility model involves arranging the louver assembly above the air outlet rather than below it. When the air conditioner supplies air, the airflow comes into contact more with the free side of the louvers after leaving the outlet. Since the louvers are suspended downwards, the airflow can flow smoothly downwards or at an angle from the outlet without being obstructed by the structure below. Simultaneously, by controlling the rotation angle of the louvers, the airflow direction can be adjusted, achieving multi-angle airflow along a primary direction and expanding the airflow coverage. Furthermore, placing the louver assembly above the air outlet avoids the flow resistance and eddy current losses caused by the louvers being located on the lower path of the airflow, reducing wind resistance and improving airflow efficiency and uniformity. This ensures effective airflow. Attached Figure Description

[0022] In existing technology, for most air conditioners, such as wall-mounted air conditioners, the air outlet is usually tilted downwards. However, the louvers are usually set on the lower side wall of the air outlet. On the one hand, the louvers occupy the lower side wall of the air outlet, limiting the design range of the downward tilting air outlet and obstructing the downward air delivery, thus suppressing the air delivery range. On the other hand, the rotation axis of the louvers creates a diversion obstruction of the airflow. During the rotation of the louvers, the airflow direction is easily disrupted by stratification, affecting the air delivery effect.

[0023] This utility model proposes an air conditioner.

[0024] Please refer to Figure 1 , Figure 2 and Figure 6 In one embodiment of this utility model, the air conditioner includes: The housing 100 has an air outlet 110, the length direction of the air outlet 110 is configured as a first direction, and the upper side of the air outlet 110 has a mounting part 120. The louver assembly includes a plurality of louvers 200 spaced apart along a first direction. The louvers 200 are rotatably suspended on the mounting part 120 via a pivot 210 and are positioned opposite to the air outlet 110.

[0025] The technical solution of this utility model arranges the louver assembly on the upper side of the air outlet 110 rather than the lower side. When the air conditioner supplies air, the airflow, after leaving the air outlet 110, comes into contact more with the free side of the louvers 200. Since the louvers 200 are suspended downwards, the airflow can flow smoothly downwards or obstructed downwards from the air outlet 110 without being blocked by the structure below the air outlet 110. Simultaneously, by controlling the rotation angle of the louvers 200, the airflow direction can be adjusted, achieving multi-angle airflow along the first direction and expanding the airflow coverage. Furthermore, placing the louver assembly on the upper side of the air outlet 110 avoids the flow resistance and eddy current losses caused by the louvers 200 being located on the lower side of the airflow path, reducing wind resistance and improving airflow efficiency and uniformity. This ensures effective airflow.

[0026] It should be noted that the upper sidewall of the air outlet 110 can extend outside the air outlet 110. Correspondingly, the mounting part 120 can be inside or outside the air outlet 110. When the mounting part 120 is inside the air outlet 110, the louver assembly adjusts the airflow direction of the air outlet 110 in a suspended manner inside the air outlet 110, guiding the airflow forward and ensuring the air delivery distance. When the mounting part 120 is outside the air outlet 110, the louver assembly adjusts the airflow direction of the air outlet 110 in a suspended manner outside the air outlet 110, achieving a greater angle change in the airflow direction and widening the air outlet angle of the air conditioner. Additionally, the distance between the free side of the louver 200 away from the rotating shaft 210 and the side of the louver 200 where the rotating shaft 210 is located can be greater than or equal to the width of the air outlet 110, that is, greater than or equal to the width of the air outlet 110 in the direction perpendicular to the first direction. Of course, the free side of the louver 200 away from the rotating shaft 210 can also be opposite to the air outlet 110 in the air outlet direction. Without loss of generality, the louver assembly also includes a connecting rod, to which the rotating shafts 210 of the multiple louvers 200 are connected. The connecting rod extends along the first direction, and the driving component is located inside the housing 100, driving the connecting rod to reciprocate along the first direction, thereby causing the multiple louvers 200 to reciprocate. The air conditioner can be a wall-mounted air conditioner or a vertical square air conditioner; this embodiment describes a wall-mounted air conditioner. The first direction is as follows... Figure 1 As shown, for a wall-mounted air conditioner, the first direction is the horizontal direction of the wall-mounted air conditioner in use, that is, the length direction of the air outlet 110 is the first direction, and the width direction of the air outlet 110 is the second direction perpendicular to the first direction, that is, the vertical direction.

[0027] In one embodiment, please refer to Figures 1 to 3 The mounting portion 120 protrudes forward from the upper edge of the air outlet 110. It should be noted that when the air conditioner is in use, the front side is the air outlet side, and the rear side is the side facing away from the air outlet side. In this embodiment, the mounting portion 120 extends forward of the air conditioner, so that the louver assembly is installed in front of the air outlet 110. During rotation adjustment, the louvers 200 can more effectively cover or guide the airflow of the air outlet 110, avoiding backflow or turbulence caused by the louvers 200's rearward installation position. Simultaneously, when the louvers 200 oscillate to deliver air, their rotation trajectory is downstream of the airflow of the air outlet 110, allowing the louvers 200 to have a larger rotation angle and less obstruction in the first direction, thereby expanding the air outlet angle of the air conditioner in the first direction and meeting the demand for large-angle air delivery. Of course, in other embodiments, the mounting portion 120 can also be located on the upper side inside the air outlet 110.

[0028] Furthermore, in this embodiment, please refer to Figures 1 to 3The housing 100 also includes an air outlet wall 130 with an air outlet 110. The air outlet wall 130 is set at an angle to the mounting part 120, forming an air outlet 160 that penetrates the housing 100 in a first direction. It is understandable that, in the first direction, the louvers 200 are exposed at the air outlet 160. The air outlet 160 expands the airflow guiding space of the air outlet 110 in the first direction, allowing the airflow to diffuse along the first direction from the wide area after leaving the air outlet 110, guided by the louvers 200. This reduces the compression and turbulence of the airflow at the outlet and increases the airflow range. At the same time, since the mounting part 120 is inclined and protrudes forward relative to the air outlet wall 130, the louver assembly suspended on it is located in the downstream guiding position of the airflow. It can guide the airflow from the air outlet 110 through angle adjustment without directly blocking the main channel. This avoids the wind resistance problem caused by the lowered louvers 200, fully utilizes the air guiding function, expands the air delivery range, and improves control flexibility. When extending from the air outlet 110 along the first direction towards both sides of the housing 100, the air outlet wall 130 can be flush with the air outlet 110 or inclined relative to the air outlet 110 to a trumpet shape.

[0029] In one embodiment, please refer to Figure 2 and Figure 3 When the louver 200 and the air outlet 110 are aligned in the same air outlet direction, one side of the louver 200 is adjacent to the air outlet 110, and the other side of the louver 200 extends at least to the side of the mounting portion 120 away from the air outlet 110. It can be understood that the air outlet 110's air outlet direction is the opening direction of the air outlet 110, not the flow direction of the airflow after passing only through the louver 200. The angle between the louver 200 and the air outlet direction is the angle between the plane containing the plate-shaped louver 200 and the air outlet direction. The alignment of the louver 200 and the air outlet 110's air outlet direction can be understood as the plate-shaped louver 200 extending in the opening direction of the air outlet 110. In other words, the angle between the louver 200 and the air outlet 110's air outlet direction is zero degrees or close to zero degrees, which represents the maximum open state of the louver 200 opening the air outlet 110. Thus, when the louvers 200 are adjusted to align with the air outlet 110's airflow direction, the span of the louvers 200 is sufficient to extend from the edge of the air outlet 110 to the front of the mounting section 120, effectively creating a cut-off air outlet 160. This forms a continuous guide surface extending downstream from the air outlet 110, effectively guiding the airflow smoothly along the surface of the louvers 200, preventing airflow separation or vortexing between the air outlet 110 and the louvers 200, thereby reducing wind resistance and improving airflow efficiency. The other side of the louvers 200 extends to the mounting section 120 away from the air outlet 110; it can be positioned directly on the front panel 140 or slightly protruding from the front panel 140, ensuring the air conditioner's aesthetics and overall integrity.

[0030] In one embodiment, please refer to Figure 1 , Figure 4 and Figure 5 The housing 100 includes a chassis 150 on the side opposite to the air outlet 110. The louvers 200 include a front side away from the air outlet 110. The louvers 200 are oscillating at least in a first direction. When the angle between the louvers 200 and the air outlet 110's airflow direction is greater than 50°, on the projection surface of the chassis 150, the front side of the louvers 200 on the side is located outside the air outlet 110. The projection on the chassis 150 is understood as a projection from the front to the rear. The oscillating arrangement of the louvers 200 in the first direction is understood as the louvers 200 rotating around a vertical axis. Thus, when the angle between the louvers 200 and the air outlet 110's airflow direction is greater than 50°, on the projection surface of the chassis 150, the front sides of the louvers 200 located on both sides in the first direction at least partially extend beyond the outline of the air outlet 110, i.e., their projected positions are outside the air outlet 110. This design allows the louver 200 to extend beyond the projection area of ​​the air outlet 110 when it swings at a large angle, effectively expanding the airflow guidance coverage. In wide-angle airflow or anti-direct-blow mode, the louver 200 can divert and guide the airflow from the air outlet 110, preventing direct airflow from colliding with redirected airflow and improving the continuity and range of airflow. Simultaneously, it indicates that the louver 200 has sufficient swing stroke. Combined with the layout of the mounting part 120 on the upper outer side of the air outlet 110, this ensures that the louver 200 maintains sufficient structural strength and airflow guiding area even during large-angle adjustments, preventing it from leaving the effective airflow guiding area due to swinging. For example, Figure 4 As shown, when the angle between the louver 200 and the air outlet 110 is 60°, on the projection surface of the chassis 150, the front edge of the louver 200 extends 3.3mm beyond the air outlet 110; Figure 5 As shown, when the angle between the louver 200 and the air outlet 110 is 70°, on the projection surface of the chassis 150, the front edge of the louver 200 extends 5mm beyond the air outlet 110. Based on this, combined with the aforementioned air outlet 160, when the louver 200 supplies air in a direction close to the first direction, the angle between the louver 200 and the air outlet direction can reach 85°, thereby achieving a maximum air supply range of close to 175°.

[0031] Furthermore, in this embodiment, please refer to Figure 4 and Figure 5The louver 200 also includes a rear side adjacent to the air outlet 110. On the projection surface of the chassis 150, when the front side coincides with the side of the air outlet 110, the front side of the louver 200 and the rear side of the adjacent louver 200 at least partially coincide. The louver 200 swings until its front side coincides with the side of the air outlet 110, which is understood as the front side of the louver 200 located on the side coinciding with the side of the air outlet 110 in the first direction. That is, during the air supply process, the gas guided by the louver 200 on the side will not be impacted by the direct airflow, ensuring the stability of the airflow guidance by the louver 200 on the side. Meanwhile, the front edge of the louver 200 and the rear edge of the adjacent louver 200 at least partially overlap in projection, indicating that multiple louvers 200 can achieve effective edge overlap in the front-back direction, forming a continuous guide surface. This avoids the situation where direct airflow collides with guide airflow due to obvious gaps between louvers 200, reducing airflow turbulence and eddy current generation. Here, direct airflow is understood as airflow not guided by the louvers 200, flowing in the direction of the opening of the air outlet 110, while guide airflow is the airflow guided backward by the louvers 200. In addition, when the side louvers 200 swing until their front edge overlaps with the side edge of the air outlet 110, there is no direct airflow in the front-back direction, ensuring that the airflow from the air outlet 110 can be completely guided by the louvers 200 and flow towards the first direction, expanding the air outlet angle and ensuring the air delivery distance after guidance.

[0032] When the angle between the louver 200 and the air outlet direction can reach 45°, it is not necessary to restrict the louver 200 located on the side to coincide with the side of the air outlet 110 in the first direction. It can be understood that within this angle range, the degree to which the louver 200 changes the air direction is low, the air direction tends to be direct, or the impact of the direct airflow and the guide airflow colliding with each other on the flow velocity is low. Correspondingly, within this swing angle range, the front side of the louver 200 and the rear side of the adjacent louver 200 can also have a gap, so as to ensure the spacing between adjacent louvers 200 and ensure the air volume. In addition, referring to the following description of the pivot 210 being located near the front side, on the projection plane of the chassis 150, the front side of the louver 200 located on the side coincides with the side of the air outlet 110 in the first direction. Therefore, the rear side of the louver 200 on the side also coincides with the side of the air outlet 110 in the first direction. This avoids the situation where the direct airflow collides with the guide airflow when the air is delivered at a large angle, thereby ensuring the air delivery range and air delivery angle of the air conditioner.

[0033] In one embodiment, please refer to Figure 1 , Figure 2 and Figure 6The housing 100 also includes a front panel 140 located on the front side of the mounting section 120, with the pivot 210 disposed adjacent to the front panel 140. It can be understood that the pivot point of the louvers 200 is positioned close to the front of the air conditioner, shifting the center of rotation of the louvers 200 forward. This allows them to adjust the airflow direction further downstream, enabling more direct and precise guidance and diversion of the airflow leaving the air outlet 110 when the louvers 200 swing to adjust the airflow direction, thus improving the accuracy of airflow control. Simultaneously, because the pivot 210 is positioned close to the front panel 140, when the louvers 200 swing to the airflow guiding state, their rear edge can be closer to the air outlet 110, which is beneficial for forming a smooth and continuous airflow guiding surface, reducing airflow separation and vortex losses, and improving airflow efficiency. Furthermore, the proximity of the pivot 210 to the front panel 140 reduces the extent to which the louvers 200 protrude outside the housing 100 during rotation, ensuring the aesthetics and neatness of the air conditioner. Specifically, in this embodiment, please refer to... Figure 2 and Figure 3 The distance from the pivot 210 to the front panel 140 is L, which satisfies: For example, L equals 10mm, 15mm, 20mm, 25mm or 30mm, etc.

[0034] In one embodiment, please refer to Figure 2 , Figure 3 and Figure 7 The louver 200 includes a front side away from the air outlet 110, and the pivot 210 is located adjacent to the front side. During rotation, the louver 200 swings with the vicinity of its front side as a fulcrum. When the louver 200 guides the airflow in the first direction, its rear side can extend significantly backward, thereby more effectively guiding the airflow to the left or right, expanding the air delivery angle range and coverage area. Simultaneously, because the pivot 210 is located close to the front side, most of the length of the louver 200 is located behind the pivot 210. During swinging, a larger airflow direction adjustment can be achieved with a smaller rotation angle, improving airflow sensitivity and control accuracy, and avoiding problems such as high wind resistance and significant airflow disturbance that are easily caused by rotating structures in the middle or rear.

[0035] The louver 200 also includes a rear side adjacent to the air outlet 110. The distance from the rotating shaft 210 to the rear side is H1, and the distance from the rotating shaft 210 to the front side is H2, satisfying the following: On the one hand, this avoids the pivot 210 from being too close to the front side, thus ensuring the structural stability of the louver 200 under airflow pressure. On the other hand, it also ensures that the rear side has a large swing amplitude when the louver 200 rotates, thereby improving the sensitivity of the louver 200 in guiding airflow. In one embodiment, H1 and H2 are in mm, the distance between the front and rear sides of the louver 200 is 80 mm, the distance from the pivot 210 to the rear side is 55 mm, the distance from the pivot 210 to the front side is 25 mm, and the distance between the upper and lower sides of the louver 200 is 63.5 mm.

[0036] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection 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 scope of protection of the present utility model.
