[0041] The following description, with reference to the accompanying drawings, describes an embodiment of the present invention: an air guide plate 110 assembly 100 for an indoor unit of an air conditioner.

[0042] like Figures 1-7 As shown, the air guide plate 110 assembly 100 for the indoor unit of an air conditioner in this embodiment of the present invention includes an air guide plate 110 and a diffuser impeller 120.

[0043] An air guide plate 110 is rotatably mounted at the air outlet 210 of the air conditioner. The air guide plate 110 is configured to open and close the air outlet 210, and a plurality of ventilation holes 111 are provided on the air guide plate 110. That is, the air guide plate 110 is movably mounted at the air outlet 210. When the air guide plate 110 moves to a position covering the air outlet 210, the air guide plate 110 closes the air outlet 210; when the air guide plate 110 moves to a position avoiding the air outlet 210, the air guide plate 110 opens the air outlet 210.

[0044] There are multiple air diffuser impellers 120, each of which is rotatably disposed on the inner side of the air guide plate 110, and each air diffuser impeller 120 is correspondingly disposed with a ventilation hole 111. The blades of each air diffuser impeller 120 are spaced apart from the inner surface of the air guide plate 110. The inner side of the air guide plate 110 is the windward side of the air guide plate 110 when it is located at the air outlet 210 of the indoor unit 200 of the air conditioner.

[0045] The following describes the specific implementation process of the air guide plate 110 assembly 100 for an indoor unit of an air conditioner according to an embodiment of the present invention with reference to the accompanying drawings.

[0046] For example Figure 7 As shown, when the air outlet 210 is opened by the air guide plate 110, the air guide plate 110 extends to the left and tilts downward. Each diffuser impeller 120 rotates under the influence of the airflow blowing out of the air outlet 210, which turbulently affects the airflow flowing downward to the left along the air guide plate 110, preventing the airflow from blowing directly onto the user. In addition, a portion of the airflow is directed to the lower side of the air guide plate 110 through the ventilation hole 111, improving the air delivery effect.

[0047] When the air outlet 210 is closed by the air guide plate 110 but air is still being discharged from the air outlet 210 (e.g., when the indoor temperature is reached), the airflow is blocked by the air guide plate 110. After passing through each diffuser impeller 120, it is blown out through the corresponding ventilation hole 111. As the airflow passes through each diffuser impeller 120, the airflow drives each diffuser impeller 120 to rotate, thereby causing the diffuser impeller 120 to have a turbulence effect on the airflow, thus reducing the feeling of direct airflow.

[0048] Compared with related technologies, the air guide plate 110 assembly 100 of this utility model embodiment includes an air guide plate 110 and a plurality of air diffuser impellers 120. The plurality of air diffuser impellers 120 are rotatably disposed on the inner side of the air guide plate 110, and the plurality of air diffuser impellers 120 correspond one-to-one with the plurality of ventilation holes 111 on the air guide plate 110. Thus, when the indoor unit 200 of the air conditioner discharges air, the airflow flows through the plurality of air diffuser impellers 120, causing the airflow to drive the air diffuser impellers 120 to rotate. The rotation of the air diffuser impellers 120 can turbulently circulate the airflow passing through them, thereby reducing the direct blowing sensation of the discharged airflow and preventing the discharged airflow from concentrating and blowing directly on the user, thus improving the user experience.

[0049] In some embodiments, such as Figure 3 As shown, each diffuser impeller 120 is coaxially arranged with its corresponding ventilation hole 111. This allows the airflow disturbed by the diffuser impeller 120 to be smoothly blown out of the corresponding ventilation hole 111, minimizing airflow loss and ensuring the air volume output of the indoor unit 200 of the air conditioner.

[0050] In addition, the impeller and the corresponding ventilation hole 111 are coaxially arranged, which can reduce the contact between the turbulence formed by the wind diffuser impeller 120 and the wall of the ventilation hole 111, thereby reducing the noise generated when the air is discharged.

[0051] like Figure 7 As shown, the indoor unit 200 of the air conditioner in this embodiment of the present invention includes a housing and an air guide plate 110 assembly 100. The indoor unit 200 of this embodiment of the air conditioner is a wall-mounted indoor unit.

[0052] An air outlet 210 extending along its length is provided on the housing. The air guide plate 110 assembly 100 is the air guide plate 110 assembly 100 of any of the above embodiments. The air guide plate 110 is rotatably disposed at the air outlet 210 and is configured to open and close the air outlet 210. When the air outlet 210 is fully open, the air guide plate 110 is located below the air outlet 210.

[0053] The indoor unit 200 of this utility model includes an air guide plate 110 assembly 100 comprising an air guide plate 110 and multiple diffuser impellers 120. The multiple diffuser impellers 120 are rotatably disposed inside the air guide plate 110, and each of the multiple diffuser impellers 120 corresponds one-to-one with a multiple ventilation hole 111 on the air guide plate 110. Thus, when the indoor unit 200 discharges air, the airflow passes through the multiple diffuser impellers 120, causing the airflow to drive the diffuser impellers 120 to rotate. The rotation of the diffuser impellers 120 can turbulently circulate the airflow passing through them, thereby reducing the direct blowing sensation of the discharged airflow and preventing the concentrated airflow from blowing directly on the user, thus improving the user experience.

[0054] In some embodiments, such as Figure 3 As shown, the distance between the closest point of each blade of each diffuser impeller 120 to the reference surface and the reference surface is 6mm to 15mm. The reference surface is the plane perpendicular to the axis of the diffuser impeller 120, where the center of the ventilation hole 111 is located. Figure 3 The dashed line in the diagram represents the reference plane, and the dotted line perpendicular to the dashed line represents the axis of the air diffuser impeller 120. The distance between the closest part of each blade of the air diffuser impeller 120 to the reference plane and the reference plane is 'a'.

[0055] Optionally, the distance between the closest point of each blade of each diffuser impeller 120 to the reference surface and the reference surface is 6 mm to 15 mm. Optionally, the distance between the closest point of each blade of each diffuser impeller 120 to the reference surface and the reference surface is 7 mm to 13 mm. Optionally, the distance between the closest point of each blade of each diffuser impeller 120 to the reference surface and the reference surface is 9 mm to 10 mm.

[0056] In other words, the air diffuser impeller 120 is spaced a certain distance from the reference surface, so that the turbulent airflow caused by each air diffuser impeller 120 can come into contact with the turbulent airflow caused by other air diffuser impellers 120 before passing through the ventilation hole 111, thereby further offsetting the direct blowing feeling of the air outlet.

[0057] The distance between each blade of each diffuser impeller 120 and the reference surface at the point closest to the reference surface is, but is not limited to, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm or 15mm.

[0058] In some embodiments, such as Figure 4As shown, the air guide plate 110 assembly 100 of this embodiment further includes a rotating arm 130, one end of which is connected to the air guide plate 110. The rotating arm 130 is configured to rotate about its other end, so that the air guide plate 110 rotates outside the air outlet 210. This allows the air guide plate 110 to be rotatably connected to the air outlet 210, enabling the air guide plate 110 to open or close the air outlet 210, while also providing a simple structure and low manufacturing cost.

[0059] Furthermore, such as Figure 3 and Figure 4 As shown, the inner surface of the air guide plate 110 is concave, and the air guide plate 110 is located below the air outlet 210 when the air outlet 210 is fully opened. Specifically, the inner surface of the air guide plate 110 is a curved surface that is concave towards the side away from the air outlet 210. Because the air guide plate 110 is located below the air outlet 210 when the air outlet 210 is fully opened, it can guide the air outlet 210 to blow downwards while minimizing air loss.

[0060] In some embodiments, such as Figures 1-4 As shown, multiple ventilation holes 111 are arranged sequentially at intervals along the length of the air guide plate 110, with the center of each ventilation hole 111 located in the middle of the air guide plate 110 in the width direction. This allows each diffuser impeller 120 to facilitate contact between the turbulent airflow and other diffuser impellers 120 before passing through the ventilation holes 111, thereby uniformly counteracting the direct blowing sensation of the exhaust air and further improving the user experience.

[0061] Furthermore, the ratio between the diameter of each vent 111 and the distance between the two longitudinally extending edges of the air guide plate 110 is 4 / 5 to 9 / 10. That is, the diameter of the vent 111 is smaller than and close to the distance between the two longitudinally extending edges of the air guide plate 110, thereby increasing the air outlet area of ​​the vent 111. This allows the airflow disturbed by the diffuser impeller 120 to be smoothly blown out from the corresponding vent 111, minimizing airflow loss and increasing the airflow volume of the indoor unit 200 of this embodiment. Moreover, the impeller is coaxially arranged with the corresponding vent 111, reducing the contact between the turbulence formed by the diffuser impeller 120 and the wall of the vent 111, thus reducing noise generated during air outlet.

[0062] In some embodiments, such as Figure 2 As shown, the air guide plate 110 is also provided with a plurality of micro-holes 112, and each ventilation hole 111 has a micro-hole 112 on its outer side. This allows the air to be blown into the room through the micro-holes 112, increasing the air volume and reducing the direct blowing sensation of the air.

[0063] Optionally, the diameter of the micropore 112 is 2 mm to 5 mm. That is, the diameter of the micropore 112 is, but is not limited to, 2 mm, 3 mm, 4 mm or 5 mm.

[0064] In some embodiments, such as Figures 4-6 As shown, the air guide plate 110 includes a main plate portion 113, a first edge portion 114, and a second edge portion 115.

[0065] Ventilation holes 111 and micro-holes 112 are disposed on the main board portion 113. A first edge portion 114 extends along the length direction of the air guide plate 110 and connects to one side of the main board portion 113. The inner surface of the first edge portion 114 is recessed relative to the inner surface of the main board portion 113, and a row of micro-holes 112 is disposed on the inner surface of the first edge portion 114, which are arranged sequentially along the length direction of the air guide plate 110. A second edge portion 115 extends along the length direction of the air guide plate 110 and connects to the other side of the main board portion 113. The inner surface of the second edge portion 115 is recessed relative to the inner surface of the main board portion 113, and a row of micro-holes 112 is disposed on the inner surface of the second edge portion 115, which are arranged sequentially along the length direction of the air guide plate 110. Thus, when the air guide plate 110 closes the air outlet 210, a portion of the main board portion 113 fits into the air outlet 210, and the inner surfaces of the first edge portion 114 and the second edge portion 115 can adhere to the outer surface of the housing, preventing air leakage from the first edge portion 114 and the second edge portion 115 to the housing, so that all airflow is blown into the room from the multiple ventilation holes 111 and / or micropores 112.

[0066] In some embodiments, each pair of adjacent diffuser impellers 120 is arranged such that they rotate in opposite or the same direction under the influence of airflow. This causes the airflow generated when adjacent diffuser impellers 120 rotate to flow in opposite or the same direction, thereby further reducing the direct blowing sensation of the exhaust air.

[0067] Specifically, the diffuser impeller 120 is provided with a rotating shaft, and the air guide plate 110 is provided with an annular cylinder with one end open. The rotating shaft of the diffuser impeller 120 is rotatably installed in the annular cylinder.

[0068] In some embodiments, such as Figure 4 As shown, each ventilation hole 111 is provided with a mounting bracket, and the corresponding air diffuser impeller 120 is rotatably mounted on the mounting bracket. This achieves the effect that the air diffuser impeller 120 can be rotatably mounted on the air guide plate 110, and the structure is simple and the manufacturing cost is low.

[0069] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
