Problems solved by technology
[0002] For traditional wall-mounted units and some vertical air conditioners, cross-flow fans are generally used to supply air. The cross-flow fans are placed in the air duct. If the air duct is too short, although it can ensure the strength of the wind, it will cause the air supply distance to be short, resulting in the inability to supply air to some places in the room. If the air duct is too long, it will cause the air supply distance to be too long. It is sent to a large indoor area, but the energy loss in the air supply process is relatively large, and the air supply intensity is small, which may easily cause insufficient air volume

Embodiment Construction
[0019] see in conjunction Figure 1 to Figure 3 As shown, according to the embodiment of the present invention, the air duct structure includes an air duct and a cross-flow vane 1 arranged in the air duct. The air duct has an air outlet 2. On the cross-section of the cross-flow vane 1, the center of the cross-flow vane 1 is The distance between the upper edge of the inner side of the air outlet 2 of the air duct is L1, the distance between the center of the cross-flow fan 1 and the lower edge of the inner side of the air outlet 2 of the air duct is L2, and the inner lower edge of the lower guide wall 4 is the lower edge. At the position where the distance between the guide wall 4 and the upper guide wall 3 is the smallest, the range of L1 / L2 is 1.59 to 2.03.
[0020] The air outlet 2 has an air inlet end and an air outlet end, wherein the distance between the center of the cross-flow vane 1 and the inner upper edge of the upper guide wall of the air duct determines the length ...

The invention provides an air duct structure and an air conditioner. The air duct structure comprises an air duct and a cross-flow fan blade (1) arranged in the air duct. The air duct is provided with an air outlet (2). The air outlet (2) comprises an upper flow guiding wall (3) and a lower flow guiding wall (4). On the section of the cross-flow fan blade (1), the distance between the center of the cross-flow fan blade (1) and the upper edge of the inner side of the upper flow guiding wall (3) is L1, the distance between the center of the cross-flow fan blade (1) and the lower edge of the inner side of the lower flow guiding wall (4) is L2, the lower edge of the inner side of the lower flow guiding wall (4) is located in the position, at the smallest distance from the upper flow guiding wall (3), of the lower flow guiding wall (4), and the range of L1 / L2 is 1.59-2.03. According to the air duct structure, it can be guaranteed that not only does the air duct structure have the sufficient air supply distance but also the air outlet has sufficient air supply strength.
Description
technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to an air duct structure and an air conditioner. Background technique [0002] For traditional wall-mounted units and some vertical air conditioners, cross-flow fans are generally used to supply air. The cross-flow fans are placed in the air duct. If the air duct is too short, although it can ensure the strength of the wind, it will cause the air supply distance to be short, resulting in the inability to supply air to some places in the room. If the air duct is too long, it will cause the air supply distance to be too long. It is sent to a large indoor area, but the energy loss in the air supply process is relatively large, and the air supply intensity is small, which may easily cause insufficient air volume. Contents of the invention [0003] Therefore, the technical problem to be solved by the present invention is to provide an air duct structure and an air...
