Abstract
Description
Technical Field
[0001] This utility model relates to the field of sliding window technology, specifically to a sliding window sill with concealed drainage. Background Technology
[0002] The construction of a single-track sliding window includes a window frame, glass, window sash, track, and handle, showcasing its simple and elegant design concept. Its opening method does not take up extra space; simply slide the window in a specific direction, highlighting its convenience and practicality. In rainy weather, water may accumulate on the surface of the bottom track. Currently, water inlets are usually designed on the bottom track profile. These inlets allow the accumulated water to flow down along the inlets and out from the outlet of the bottom track profile.
[0003] However, this drainage method can cause water to overflow into the room due to untimely drainage in cases of heavy rain and water accumulation. To solve this problem, a concealed drainage channel is designed in the lower frame or horizontal mullion. This drainage method is beneficial for drainage, but this concealed drainage channel lacks a windproof structure, which can easily cause rainwater to backflow into the window frame during rainy days, affecting drainage. Utility Model Content
[0004] The purpose of this utility model is to provide a sliding window sill with concealed drainage to address the aforementioned shortcomings in the prior art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A sliding window sill with concealed drainage includes a bottom frame with at least one water inlet and at least one water outlet. A windbreak assembly is provided at each water outlet, comprising a windbreak block disposed within the outlet. The water outlet includes a first water outlet channel and a second water outlet channel, with the end of the first water outlet channel facing the top of the windbreak block and the end of the second water outlet channel facing the bottom of the windbreak block. A telescopic rod and a guide post are fixedly connected to the bottom of the windbreak block. A sliding plate is fixedly connected to the telescopic rod and slidably connected within the second water outlet channel. The sliding plate has a guide groove adapted to the guide post.
[0007] Furthermore, the windbreak block is conical in shape, with a water inlet at the top and multiple connecting grooves communicating with the water inlet on the windward side. A support block is fixedly installed at the bottom of the windbreak block, and the support block abuts against the inside of the bottom frame. A fluid cavity is formed between the bottom of the windbreak block and the bottom frame.
[0008] Furthermore, the second water outlet channel is configured in a bent manner.
[0009] Furthermore, a step is provided at the outlet of the second water outlet channel, and a protective plate is rotatably installed at the second water outlet channel. The step is located on the side near the middle of the bottom frame to restrict the protective plate from rotating towards the middle of the bottom frame.
[0010] Furthermore, the water inlet includes a first water inlet channel and a second water inlet channel, and the bottom frame is also provided with a first water inlet cavity and a second water inlet cavity. The first water inlet cavity is connected to the first water inlet channel and the second water inlet channel, and the second water inlet cavity is connected to the second water inlet channel and the first water outlet channel.
[0011] Furthermore, the bottom frame is equipped with multiple sealing strips and insulation cotton.
[0012] In the above technical solution, the sliding window sill with concealed drainage provided by this utility model has the following beneficial effects:
[0013] With the windbreak block in place, outside wind enters through the second water outlet channel and pushes the slide plate towards the windbreak block, causing the guide post to insert into the guide groove. This seals the second water outlet channel, preventing rainwater from flowing back in. Rainwater from the first water outlet channel flows through the windbreak block to the upper side of the slide plate. When the force of the rainwater's own weight on the slide plate is greater than the force of the air on the slide plate, the slide plate moves away from the windbreak block, causing the guide post to disengage from the guide groove. This allows the rainwater to enter the second water outlet channel from the guide groove and be discharged from the bottom frame.
[0014] It should be understood that the foregoing general description and the following detailed description are exemplary and illustrative only, and are not intended to limit this disclosure.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.
[0025] Please see Figure 1-5 A sliding window sill with concealed drainage includes a bottom frame 1. At least one water inlet 2 and at least one water outlet 3 are respectively provided on the bottom frame 1. A windbreak assembly 4 is provided at each water outlet 3. The windbreak assembly 4 includes a windbreak block 41 disposed within the water outlet 3. The water outlet 3 includes a first water outlet channel 31 and a second water outlet channel 32. The end of the first water outlet channel 31 faces the top of the windbreak block 41, and the end of the second water outlet channel 32 faces the bottom of the windbreak block 41. A telescopic rod 42 and a guide post 43 are fixedly connected to the bottom of the windbreak block 41. A sliding plate 45 is fixedly connected to the telescopic rod 42. The sliding plate 45 is slidably connected within the second water outlet channel 32, and a guide groove 44 adapted to the guide post 43 is provided on the sliding plate 45.
[0026] After the outside wind enters through the second water outlet channel 32, it pushes the slide plate 45 towards the windbreak block 41, causing the guide post 43 to be inserted into the guide groove 44, thereby sealing the second water outlet channel 32 with the slide plate 45 to prevent rainwater from flowing back in; the rainwater in the first water outlet channel 31 flows through the windbreak block 41 to the upper side of the slide plate 45. When the force of the rainwater's own weight on the slide plate 45 is greater than the force of the air on the slide plate 45, the slide plate 45 moves away from the windbreak, and the guide post 43 disengages from the guide groove 44, thereby allowing the rainwater to enter the second water outlet channel 32 from the guide groove 44 and be discharged from the bottom frame 1.
[0027] Furthermore, the windbreak block 41 is conical in shape, with a water inlet 46 at the top and multiple connecting grooves 47 communicating with the water inlet 46 on the windward side of the block. A support block is fixedly provided at the bottom of the windbreak block 41, and the support block abuts against the inside of the bottom frame 1. A fluid cavity 48 is formed between the bottom of the windbreak block 41 and the bottom frame 1.
[0028] Rainwater flows sequentially through the first water outlet channel 31, the water storage port 46, the connecting channel, the fluid cavity 48, and the guide channel 44, and is discharged from the second water outlet channel 32.
[0029] Furthermore, the second water outlet channel 32 is designed with a bend. This further reduces the intensity of external wind and facilitates drainage.
[0030] Furthermore, a step 33 is provided at the outlet of the second water outlet channel 32, and a protective plate 34 is rotatably provided at the second water outlet channel 32. The step 33 is located on one side near the middle of the bottom frame 1 to restrict the protective plate 34 from rotating towards the middle of the bottom frame 1.
[0031] While the above solution can prevent rainwater backflow, its drainage efficiency is low. By setting up a protective plate 34, which is restricted by the step 33, the protective plate 34 can only rotate toward the outlet of the second water outlet channel 32. That is, the outside wind and rainwater are blocked by the protective plate 34 and cannot enter the second water outlet channel 32. The rainwater in the second water outlet channel 32 can push the protective plate 34 to rotate and then be discharged, effectively improving the drainage efficiency.
[0032] Furthermore, the water inlet 2 includes a first water inlet channel 21 and a second water inlet channel 22. The bottom frame 1 is also provided with a first water inlet cavity 23 and a second water inlet cavity 24. The first water inlet cavity 23 is connected to the first water inlet channel 21 and the second water inlet channel 22, and the second water inlet cavity 24 is connected to the second water inlet channel 22 and the first water outlet channel 31.
[0033] Rainwater enters the first water inlet channel 21, the first water inlet chamber 23, the second water inlet channel 22, and the second water inlet chamber 24 in sequence, until it enters the first water outlet channel 31.
[0034] Furthermore, the bottom frame 1 is provided with multiple sealing strips 5 and thermal insulation cotton 6. The sealing strips 5 and thermal insulation cotton 6 improve the sealing and thermal insulation performance of the bottom frame 1; these are technical means commonly used by those skilled in the art and will not be described in detail here.
[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
