[0026] Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.
[0027] Please refer to Figure 1 , Figure 2 As shown, an embodiment of this utility model provides a rainproof and ventilated skylight 10. This rainproof and snowproof skylight 10 can be installed on steel roofs, wooden roofs, tiled roofs, and other various locations. The rainproof and ventilated skylight 10 can maintain indoor and outdoor air circulation while preventing rain, snow, insects, debris, etc. from entering the room.
[0028] The specific structure of the rainproof and ventilated skylight 10 is as follows: The rainproof and ventilated skylight 10 mainly consists of a frame 11 and at least three rainproof layers. The number of rainproof layers can be set as needed, for example, three, four, or five. Generally speaking, in this embodiment, three rainproof layers are more suitable. The following is a detailed discussion of each component of the rainproof and snowproof ventilated skylight 10.
[0029] The structure of frame 11 is not limited; it can be roughly rectangular, with the middle portion of frame 11 exposed. Of course, in other embodiments, frame 11 can also be circular, polygonal, or irregular. The size and thickness of frame 11 are not limited and can be adjusted according to actual needs.
[0030] The frame 11 can be fixed to the roof or other parts on all four sides. The connection method between the two is not limited, such as by threaded fasteners, welding, riveting and other methods.
[0031] The material of frame 11 is not limited and can be stainless steel, aluminum, plastic, etc. The size of frame 11 can be set as needed, which will not be elaborated here.
[0032] Three rainproof layers are distributed vertically within the frame 11, covering or substantially covering the middle part of the frame 11.
[0033] For ease of description, the three rainproof layers are defined as the first rainproof layer 121, the second rainproof layer 122, and the third rainproof layer 123, respectively. The second rainproof layer 122 is located below the first rainproof layer 121, and the third rainproof layer 123 is located below the second rainproof layer 122.
[0034] Each rainproof layer includes several spaced-apart rainproof panels with gaps between adjacent panels. The number, length, and width of the rainproof panels can be set according to the dimensions of the frame 11 and other requirements, as long as the laid rainproof layer can cover or substantially cover the hollow portion of the frame 11. Specifically, the first rainproof layer 121 includes several first rainproof panels 130, the second rainproof layer 122 includes several second rainproof panels 131, and the third rainproof layer 123 includes several third rainproof panels 132. The number of first rainproof panels 130, second rainproof panels 131, and third rainproof panels 132 can be the same or different. In this embodiment, the number of first rainproof panels 130, second rainproof panels 131, and third rainproof panels 132 is the same, and they are staggered one-to-one along the vertical direction.
[0035] Each rainproof panel is fixed to the two inner walls of the frame 11 at both ends. The connection method is not limited, such as plug-in, connection by threaded fasteners, welding, integral molding, etc.
[0036] The rainproof panels of two adjacent rainproof layers are staggered and tilted in opposite directions. For example, the first rainproof panel 130 is higher on the left and lower on the right, the second rainproof panel 131 is lower on the left and higher on the right, and the third rainproof panel 132 is higher on the left and lower on the right, or the first rainproof panel 130 is lower on the left and higher on the right, the second rainproof panel 131 is higher on the left and lower on the right, and the third rainproof panel 132 is lower on the left and higher on the right, etc. The bottom end of the first rainproof panel 130 can be close to the middle or upper half of the second rainproof panel 131, and the bottom end of the second rainproof panel 131 can be close to the middle or upper half of the third rainproof panel 132, so that rainwater flowing down through the first rainproof panel 130 can fall smoothly onto the second rainproof panel 131, and rainwater flowing down through the second rainproof panel 131 can fall smoothly onto the third rainproof panel 132.
[0037] Each rainproof panel is installed at an angle, and the angle of the rainproof panel can be set as needed, such as 15°, 30°, 40°, etc.
[0038] Each rainproof panel has a main drainage ditch 133 at its bottom. The shape and depth of the main drainage ditch 133 can be set as needed. The main drainage ditch 133 can be used to drain rainwater.
[0039] In this embodiment, the main drainage channels 133 of the first rainproof plate 130 and the second rainproof plate 131 can both be V-shaped, while the main drainage channel 133 of the third rainproof plate 132 is a first trapezoid, wherein the upper opening width of the first trapezoid is greater than the bottom width. Furthermore, a protrusion 135 can be provided within the main drainage channel 133 of the third rainproof plate 132, located at the bottom of the main drainage channel 133. The shape of the protrusion 135 is not limited, in order to reduce the flow velocity of rainwater and prevent rainwater from rushing out of the main drainage channel 133 due to excessive speed. Of course, in some embodiments, the protrusion 135 may not be provided within the main drainage channel 133 of the third rainproof plate 132, or the main drainage channels 133 of the first rainproof plate 130 and the second rainproof plate 131 may be U-shaped or trapezoidal, etc. In addition, a smooth transition section can be provided at the end of the main drainage channel 133 of the second rainproof plate 131 to avoid rainwater splashing.
[0040] In addition, in order to further reduce the water flow in the main drainage ditch 133, an auxiliary drainage ditch 134 can be provided in the middle of some or all of the rainproof panels. The auxiliary drainage ditch 134 can also help to drain some rainwater and reduce the rainwater flow into the main drainage ditch 133.
[0041] The depth of the upper auxiliary drainage ditch 134 is greater than that of the lower auxiliary drainage ditch 134. This is because the rainwater flow is greater in the upper rainproof layer, and the auxiliary drainage ditch 134 can discharge more rainwater, while the amount of rainwater flowing to the lower part will decrease, which can effectively prevent rainwater from being washed out from the lower main drainage ditch 133.
[0042] In this embodiment, auxiliary drainage ditches 134 can be provided on some of the rainproof panels. Specifically, a first auxiliary drainage ditch is provided in the middle of the first rainproof panel 130, and a second auxiliary drainage ditch is provided in the middle of the second rainproof panel 131. The depth of the first auxiliary drainage ditch is greater than the depth of the second auxiliary drainage ditch.
[0043] The third rainproof plate 132 does not need to be equipped with an auxiliary drainage ditch 134 because the flow rate of rainwater has been greatly reduced after passing through the main drainage ditch 133 and auxiliary drainage ditch 134 of the first rainproof plate 130 and the second rainproof plate 131, and there is no longer a large drainage requirement. The third rainproof plate 132 includes a downstream surface, and the slope of the upper half of the downstream surface is less than the slope of the lower half.
[0044] The style of the auxiliary drainage ditch 134 is not limited. For example, in this embodiment, the first auxiliary drainage ditch and the second auxiliary drainage ditch are formed in a second trapezoidal shape by the rainproof board protruding upwards. Here, "protruding upwards" means protruding upwards from the plane where the rainproof board is located. Figure 1 For example, the second trapezoid of the first auxiliary drainage ditch protrudes to the upper right, and the second trapezoid of the second auxiliary drainage ditch protrudes to the upper left. This design allows rainwater to flow down as smoothly as possible without splashing. If the auxiliary drainage ditch 134 were formed into a rectangle by protruding upwards through a rainproof plate, the top corner of the auxiliary drainage ditch 134 would be too sharp, and rainwater flowing out of the auxiliary drainage ditch 134 might fly out.
[0045] In the third rainproof layer 123, the projections of two adjacent third rainproof panels 132 on the horizontal plane partially overlap. That is, the projections of the first end of one third rainproof panel 132 and the second end of the adjacent third rainproof panel 132 on the horizontal plane partially overlap, thereby preventing rainwater from falling into the room through the gap between the two adjacent third rainproof panels 132. In the first rainproof layer 121, the projections of two adjacent first rainproof panels 130 on the horizontal plane may partially overlap or not overlap; in the second rainproof layer 122, the projections of two adjacent second rainproof panels 131 on the horizontal plane may partially overlap or not overlap.
[0046] The working principle of the rainproof and ventilated skylight 10 provided in this embodiment is as follows:
[0047] Airflow channels are formed between adjacent rainproof panels of each rainproof layer and between two adjacent rainproof layers, allowing indoor and outdoor air to exchange through these channels;
[0048] When it rains, the rainwater first falls on the first rainproof plate 130 of the first rainproof layer 121, and then flows down along the inclined direction of the first rainproof plate 130. Some of the rainwater collects in the first auxiliary drainage ditch and is discharged to both ends, while some of the rainwater continues to flow downward and then passes through the main drainage ditch 133 of the first rainproof plate 130. Among them, some of the rainwater is discharged to both ends through the main drainage ditch 133, and some of the rainwater falls into the second rainproof layer 122.
[0049] Rainwater flows down along the inclined direction of the second rainproof board 131. Some of the rainwater collects in the second auxiliary drainage ditch and is discharged to both ends. Some of the rainwater continues to flow downward and then passes through the main drainage ditch 133 of the second rainproof board 131. Among them, some of the rainwater is discharged to both ends through the main drainage ditch 133, and some of the rainwater falls into the third rainproof layer 123.
[0050] The remaining rainwater flows along the downstream surface of the third rainproof plate 132 into the main drainage ditch 133, and then is discharged to both ends.
[0051] The above steps can be added, removed, modified, or their order adjusted as needed.
[0052] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
