[0025] The preferred embodiments of the present application are described below in conjunction with the accompanying drawings, and it should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application.

[0026] In the first aspect, the embodiment of the present application provides a water guide structure applied to a window type air conditioner, and aims to solve the problem that the existing water guide structure has an adverse effect on the fan air inlet while blocking the splashing of condensed water.

[0027] As shown in Figures 1 to 4 , the water guide structure mainly includes a ring-shaped water guide ring 10, a first air inlet 11, a second air inlet 12, a plurality of first water guide plates 30 and a plurality of second water guide plates 40.

[0028] The ring-shaped water guide ring 10 is arranged around the fan 20 of the window type air conditioner, and its function is to form a boundary for water guide and airflow; the radial outer side of the ring-shaped water guide ring 10 is provided with the first air inlet 11 and the second air inlet 12; the first air inlet 11 and the second air inlet 12 are respectively located at different sides of the ring-shaped water guide ring 10, specifically, if the fan 20 is designed to rotate clockwise, then the first air inlet 11 is located in the first half of the rotation direction of the fan 20, and the second air inlet 12 is located in the second half of the rotation direction of the fan 20, on the contrary, if the fan 20 is designed to rotate counterclockwise, then the second air inlet 12 is located in the first half of the rotation direction of the fan 20, and the first air inlet 11 is located in the second half of the rotation direction of the fan 20, in this way, no matter the rotation direction of the fan 20, at least one air inlet can play a role in guiding the airflow to enter.

[0029] A plurality of first water guide plates 30 are arranged at intervals in the first air inlet 11, and the plurality of first water guide plates 30 are configured to guide the liquid droplets splashed by the clockwise rotation of the fan 20 to a first predetermined area; a plurality of second water guide plates 40 are arranged at intervals in the second air inlet 12, and the plurality of second water guide plates 40 are configured to guide the liquid droplets splashed by the counterclockwise rotation of the fan 20 to a second predetermined area. In this embodiment, the first predetermined area and the second predetermined area are both the bottom plate of the window air conditioner, for collecting the guided condensed water. Specifically, in this embodiment, the side of the first water guide plate 30 and the second water guide plate 40 away from the fan 20 is designed as a downwardly extending structure, so that the liquid droplets splashed by the rotation of the fan 20 can finally be guided to the bottom plate of the window air conditioner along the extension direction of the second water guide plate 30, i.e. as shown in Figure 4 the first air inlet channel is formed between two adjacent first water guide plates 30, and the second air inlet channel is formed between two adjacent second water guide plates 40, which not only blocks the splashing of condensed water, but also provides a smooth path for the entry of air flow, ensuring sufficient air intake while ensuring water guiding function, and making full use of the negative pressure area at the back of the fan, thereby effectively improving the air supply and refrigeration efficiency of the window air conditioner, achieving the dual optimization of water guiding function and air intake improvement.

[0030] In some embodiments, as shown in Figure 1 , Figure 2 each first water guide plate 30 is in an arc shape, and the concave surface of the arc shape faces the opposite direction of the clockwise rotation direction of the fan 20; each second water guide plate 40 is in an arc shape, and the concave surface of the arc shape faces the opposite direction of the counterclockwise rotation direction of the fan 20. The arc-shaped first water guide plate 30 and the arc-shaped second water guide plate 40 can more smoothly guide the liquid droplets to the predetermined area, i.e. the bottom plate of the window air conditioner, reducing the probability of splashing of the liquid droplets and improving the water guiding efficiency.

[0031] In some embodiments, the plurality of first water guide plates 30 are integrally formed with the annular water guide ring 10, and the plurality of second water guide plates 40 are integrally formed with the annular water guide ring 10. Integrally formed means that the first water guide plate 30 and the second water guide plate 40 can be completed by one-time injection molding or other molding processes with the annular water guide ring 10, without the need for additional assembly steps, which can reduce manufacturing costs and eliminate the risk of connection gaps or looseness caused by separate assembly, so that the annular water guide ring 10, the first water guide plate 30 and the second water guide plate 40 form a whole structure, improving the overall strength and stability of the structure and reducing the risk of failure caused by loose or falling parts.

[0032] In some embodiments, the axial length of the annular water guide ring 10 is greater than the axial length of the fan 20. When the fan 20 rotates at high speed or the wind force is strong, if the lengths of the first water guide plate 30 and the second water guide plate 40 are insufficient, some droplets may directly pass over the top of the water guide plate, thereby reducing the water guiding effect. However, when the axial lengths of the first water guide plate 30 and the second water guide plate 40 are greater than the axial length of the fan 20, droplets can be effectively prevented from passing over the water guide plate, so as to more effectively intercept condensate and confine it within a predetermined area to avoid splashing.

[0033] In some embodiments, the inner wall surface of the annular water guide ring 10 is an arc surface coaxial with the rotation axis of the fan 20, and a predetermined gap is provided between the inner wall surface of the annular water guide ring 10 and the outer edge of the fan 20. By using an arc surface, the collision and friction of airflow on the inner walls of the first water guide plate 30 and the second water guide plate 40 are reduced, thereby reducing the noise during operation. Moreover, when condensate is thrown onto the inner wall surface, due to the guidance of the arc surface, the condensate is more likely to slide down the inner wall surface to the predetermined area, reducing the risk of condensate remaining on the first water guide plate 30 and the second water guide plate 40.

[0034] Secondly, such as Figure 3 , Figure 4 As shown, this application embodiment provides a window air conditioner, including any of the water guiding structures in the first aspect, and a fan bracket 50. The fan bracket 50 is provided with a plurality of connecting arms 60 extending radially along the annular water guiding ring 10. The annular water guiding ring 10 is connected to the fan bracket 50 through the connecting arms 60. In specific implementation, the annular water guiding ring 10, the connecting arms 60, and the fan bracket 50 are integrally formed, ensuring that the water guiding structure remains stable and reliable during air conditioner operation, without loosening or deformation.

[0035] The water-guiding structure and window air conditioner provided in this embodiment, by setting dual air inlets on the annular water-guiding ring located in the front and rear half of the fan blade rotation direction respectively, and arranging multiple water-guiding plates extending in opposite directions in each air inlet, not only achieves efficient interception and precise guidance of condensate thrown out by the motor in different rotation directions, reliably guiding it to a predetermined area to prevent moisture from corroding the internal components of the air conditioner, but also fully ensures that there is sufficient airflow to smoothly enter the fan regardless of the motor rotation direction, greatly increasing the effective air intake area of ​​the fan, and achieving dual optimization of water guidance and air intake, thereby significantly improving the cooling efficiency and energy efficiency ratio of the window air conditioner, and effectively improving product performance and reliability.
