Description

Technical Field

[0001] This invention relates to the field of louver structure technology, and more specifically, to a built-in horizontally opening and closing louver structure. Background Technology

[0002] Venetian blinds are a common interior design feature in newly built homes, and they are almost always used in the renovation of newly constructed buildings. Unlike the soft texture of curtains, Venetian blind slats are generally made of materials such as wood, glass, and aluminum alloy, making them resistant to sunlight, wind, rain, and dust, and easy to clean.

[0003] In some new home renovations, to improve space utilization, air conditioners are often installed on outdoor platforms. These platforms are typically pre-installed during construction. After the outdoor unit is installed, louvers are installed around the platform for aesthetic purposes and to protect the unit, enhancing the overall appearance. Secondly, when installing the louvers, a gap is usually left between the louvers and the edge of the platform; that is, the louvers are built-in. This allows workers to easily step on them when performing outdoor maintenance on the outdoor unit, and the extra space also contributes to a more aesthetically pleasing spatial layout.

[0004] However, existing louvered windows, typically bolted to a platform, offer good protection, but when the air conditioner needs repair, workers must disassemble them and move them indoors, posing a risk of them falling. Furthermore, during windy and rainy weather, the exterior wall can easily detach, allowing rainwater mixed with debris to flow down the wall and onto the louvered slats. Under gravity, this water and debris then run along the wall onto the glass, making it difficult to clean. Summary of the Invention

[0005] The purpose of this invention is to provide a built-in horizontally opening and closing louver structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention aims to provide a built-in horizontally opening and closing louver structure, including a louver body and a rolling support device for supporting the louver body at the bottom of the louver body. The rolling support device is also used to slide in a slide rail pre-fixed on a platform. The slide rail is used to collect rainwater and impurities sliding off the louver body, and the bottom of the slide rail is connected to a drain pipe.

[0007] The louver body frame is provided with a floating part. When the rainwater in the slide rail increases, the floating part drives the cleaning part provided above the drain pipe to rotate. The cleaning part cleans the impurities attached to the filter plate inside it, and the filter plate is lifted upward under the action of the cleaning part, so that a gap is created between the filter plate and the cleaning part.

[0008] The floating part floats upward and drives the ejector part in the discharge pipe to move upward. The ejector part pushes the ejector ring on the outside of the cleaning part upward, so as to discharge the cleaned impurities from the gap. The discharged impurities fall into the branch pipe next to the discharge pipe under the guidance of the ejector part.

[0009] As a further improvement to this technical solution, the floating part consists of a floating column and a friction wheel. The bottom of the friction wheel is rough. Multiple strip grooves are opened on the outside of the floating column. The strip grooves and multiple limiting rods fixed on the friction wheel are slidably connected. The top of the floating column is coaxially connected to the floating plate inside the outer shell. The outer shell is threaded to the cavity inside the frame of the louver body. The bottom of the cavity is a smooth surface.

[0010] As a further improvement to this technical solution, a friction plate is fixedly connected to the floating plate, and a belt is attached to the inner side of the friction plate. The contact surface between the friction plate and the belt is rough. When the friction plate moves upward, the belt is used to drive the wheel of the coaxially connected blade to rotate, so that the blade gradually closes.

[0011] As a further improvement to this technical solution, the ejector part includes a baffle and top rods symmetrically arranged on both sides of the top of the baffle. The size of the baffle is larger than the connection port of the branch pipe and the discharge pipe, and the baffle slides in the vertical groove opened in the inner wall of the discharge pipe to realize the opening and closing of the connection port.

[0012] As a further improvement to this technical solution, the push rod passes through the slide rail, and its top end is inserted into the push ring. The push ring is symmetrically embedded in the slide rail, and the inner side of the push ring is a slope. When the push ring moves upward, the impurities on the inner side are discharged from the gap.

[0013] As a further improvement to this technical solution, the side of the baffle away from the branch pipe is connected to the flip filter plate by a traction rope. The flip filter plate is located on the opposite side of the baffle and is rotatably connected to the inner wall of the discharge pipe. When the flip filter plate rotates clockwise, the cleaned impurities are guided into the branch pipe by the flip filter plate, and rainwater flows through the flip filter plate.

[0014] As a further improvement to this technical solution, the top center of the baffle is connected to an iron block embedded in the slide rail via a pull rope. Under normal conditions, the iron block is attracted to a magnet at the bottom of the rotatably connected floating column.

[0015] As a further improvement to this technical solution, the cleaning part includes a collar and a cleaning block. The inner side of the collar is threadedly connected to a filter plate, and the outer side is fitted with an ejector ring. The end of the cleaning block is fixedly connected to a support rod that is slidably connected to the collar. A second spring is sleeved on the support rod, and multiple prisms are provided on the outer side of the support rod to limit the rotation of the cleaning block.

[0016] As a further improvement to this technical solution, the bottom of the filter plate is fixedly connected to multiple support legs in an array, the support legs are threadedly connected to collars, and the support legs are slidably connected to slide rails in the vertical direction.

[0017] As a further improvement to this technical solution, the rolling support device includes rollers and a sliding rod that slidably connects the rollers. The two ends of the sliding rod are fixedly connected to the louver body. A first spring is sleeved on the sliding rod between the two rollers. The limiting rods coaxially connected on both sides of the rollers slide in the limiting groove opened in the inner wall of the slide rail. The two ends of the slide rail are rotatably connected to sealing plates, and the sealing plates are fixed by spring locks on the slide rail.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. In this built-in horizontally opening and closing louver structure, rainwater and impurities flowing through the louver body are collected by the slide rail. When the filter plate is blocked by impurities, the water level in the slide rail rises, and the floating part drives the cleaning part to rotate. The cleaning part cleans the impurities on the filter plate, thereby ensuring smooth drainage and preventing rainwater from overflowing after the top ring is blocked, which would affect the cleanliness of the glass.

[0020] 2. In this built-in horizontally opening louver structure, the cleaned impurities fall onto the outer inclined surface of the ejector ring under the action of gravity. When the push rod moves upward, it pushes the ejector ring upward, causing the impurities inside the baffle to be discharged from the gap formed by the misalignment of the filter plate and the collar ring. Guided by the flip filter plate, the impurities are discharged into the branch pipe, and rainwater flows through the flip filter plate, thereby achieving the effect of separating and discharging impurities and rainwater, and improving the urban environment.

[0021] 3. In this built-in horizontally opening louver structure, the louver bodies on both sides open and close horizontally. When repairing the indoor unit of the air conditioner, simply open the spring locks on both sides and slide the louver bodies on both sides to repair the outdoor unit. The operation is simple.

[0022] 4. In this built-in horizontally opening and closing louver structure, the baffle will close the connection when rainwater is discharged from the discharge pipe, thereby preventing rainwater from sliding down the inner wall of the discharge pipe into the branch pipe and affecting the classified discharge of impurities and rainwater, thus achieving the classified discharge of rainwater and impurities.

[0045] The technical solutions of this invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention. Example

[0046] like Figure 1 , Figure 2 and Figure 10 As shown, a built-in horizontally opening and closing venetian blind structure is provided, including a venetian blind body 100 and a rolling support device 130 at the bottom of the venetian blind body 100 for supporting the venetian blind body 100. The rolling support device 130 is also used to slide in a slide rail 110 pre-fixed on a platform. The slide rail 110 is used to collect rainwater and impurities sliding down from the venetian blind body 100, and the bottom of the slide rail 110 is connected to a drain pipe 120. Rainwater and impurities first slide down along the frame and blades of the venetian blind body 100 into the slide rail 110. The rainwater is discharged into a drain pipe through the drain pipe 120, while the impurities are filtered in the slide rail 110 for later classified discharge.

[0047] Secondly, a floating part 200 is provided inside the frame of the louver body 100. When the amount of rainwater in the slide rail 110 increases, the floating part 200 drives the cleaning part 400 provided above the drain pipe 120 to rotate. The cleaning part 400 cleans the impurities attached to the filter plate 320 inside it. Under the action of the cleaning part 400, the filter plate 320 is lifted upward, creating a gap between the filter plate 320 and the cleaning part 400. This allows the impurities to be discharged from the gap into the drain pipe 120, preventing the impurities from clogging the filter plate 320 and causing the rainwater in the slide rail 110 to overflow and affect the cleanliness of the glass.

[0048] At the same time, the floating part 200 floats upward and drives the ejector part in the discharge pipe 120 to move upward. The ejector part pushes the ejector ring 310 on the outside of the cleaning part 400 upward, so as to discharge the cleaned impurities from the gap. The discharged impurities fall into the branch pipe next to the discharge pipe 120 under the guidance of the ejector part, thereby realizing the classified discharge of impurities and rainwater.

[0049] Based on the above structure, combined with Figure 3 The specific structure of the rolling support device 130 is shown. The rolling support device 130 includes a roller 131 and a slide rod 133 that is slidably connected to the roller 131. The two ends of the slide rod 133 are fixedly connected to the louver body 100. A first spring 134 is sleeved on the slide rod 133 between the two rollers 131. The limiting rod 132, which is coaxially connected to both sides of the roller 131, slides in the limiting groove 111 opened in the inner wall of the slide rail 110. The two ends of the slide rail 110 are rotatably connected to sealing plates. The sealing plates are fixed by spring locks on the slide rail 110.

[0050] Therefore, when the outdoor unit of the air conditioner on the platform malfunctions, the spring lock is opened (spring lock is common knowledge and will not be elaborated here). By sliding the louver body 100 to both sides, when the outermost limiting rod 132 slides to the end of the limiting groove 111, the limiting rod 132 is restricted. At this time, the roller 131 at this position slides on the slide rod 133. As the louver body 100 moves, there is enough distance between the two louver bodies 100 for workers to operate, which facilitates operation and improves maintenance efficiency.

[0051] Therefore, based on the above structure, combined with Figure 5 The structure of the floating part 200 is further disclosed. The floating part 200 consists of a floating column 201 and a friction wheel 202. The bottom of the friction wheel 202 is rough. Multiple strip grooves are opened on the outside of the floating column 201. The strip grooves are slidably connected to multiple limiting rods 210 fixed on the friction wheel 202. The top of the floating column 201 is coaxially connected to the floating plate 203 rotatably connected inside the outer shell. The outer shell is threaded to the cavity inside the frame of the louver body 100. The bottom of the cavity is a smooth surface.

[0052] On the other hand, cooperation Figure 4 As shown, a friction plate 102 is fixedly connected to the floating plate 203. A belt 101 is attached to the inner side of the friction plate 102, and the contact surface between the friction plate 102 and the belt 101 is rough. When the friction plate 102 moves upward, the belt 101 drives the wheel of the coaxially connected blade to rotate, so that the blade gradually closes, thereby preventing external rainwater from entering the platform and thus protecting the air conditioner.

[0053] Therefore, as the amount of rainwater in the slide rail 110 gradually increases, the buoyancy of the floating column 201 and the floating plate 203 is used to make the floating column 201 drive the friction wheel 202 to rotate. At the same time, the upward floating column 201 pushes the top friction plate 102 to move upward. The roughness of the friction plate 102 and the belt 101 is used to increase the friction force, thereby driving the belt 101 to rotate, so that multiple blades gradually flip towards the closing direction in order to restrict the external rainwater.

[0054] It should be noted that under normal conditions (i.e., when there is no rainwater in the slide rail 110), the bottom of the friction wheel 202 is in contact with the bottom of the inner wall of the slide rail 110. Secondly, during the upward movement and rotation of the floating column 201, because the friction plate 102 abuts against the belt 101, the resistance of the belt 101 to the rotation of the friction plate 102 is greater than the friction between the floating column 201 and the floating plate 203, thereby ensuring that the friction plate 102 smoothly drives the belt 101 to rotate upward.

[0055] As rainwater gradually increases in the slide rail 110, impurities also accumulate on the filter plate 320, causing blockage and affecting rainwater drainage. If the impurities on the filter plate 320 are not cleaned in time, rainwater will overflow from the slide rail 110, thereby contaminating the glass on the next floor and increasing the difficulty of cleaning.

[0056] Thus, as the friction wheel 202 rotates, it drives the cleaning part 400 to rotate, and the cleaning part 400 cleans the impurities clogging the filter plate 320, thereby cleaning the surface of the filter plate 320 and ensuring smooth rainwater drainage.

[0057] Therefore, returning to Figure 10 and cooperate Figure 5 and 11 The structure of the cleaning unit 400 is disclosed below. The cleaning unit 400 includes a collar 401 and a cleaning block 402. The inner side of the collar 401 is threaded to the filter plate 320, and the outer side is fitted with the ejector ring 310. The end of the cleaning block 402 is fixedly connected to a support rod 403, which is slidably connected to the collar 401. A second spring 404 is sleeved on the support rod 403, and multiple prisms are provided on the outer side of the support rod 403 to limit the rotation of the cleaning block 402. In this way, when impurities clog the filter plate 320, the friction between the friction wheel 202 and the collar 401 causes the friction wheel 202 on both sides to drive the collar 401 to rotate. The cleaning block 402 rotates synchronously with the collar 401, thereby scraping off the impurities on the filter plate 320. The scraped impurities fall along the surface of the collar 401 onto the inclined surface of the ejector ring 310, thus collecting the impurities.

[0058] Furthermore, because multiple support legs 321 are fixedly connected to the bottom of the filter plate 320 in an array, and the support legs 321 are threadedly connected to the collar 401, and the support legs 321 are slidably connected to the slide rail 110 in the vertical direction, the rotating collar 401, under the action of the threads, causes the filter plate 320 to move upward. The multiple support legs 321 restrict the rotation of the filter plate 320, and as the top rod 302 rises, the filter plate 320 also pushes the cleaning block 402 to move upward. At this time, the second spring 404 is continuously compressed, the elastic potential energy increases, and the cleaning block 402 fits more tightly with the filter plate 320, so as to clean the firmly attached impurities on the filter plate 320.

[0059] It should be noted that when the second spring 404 is compressed to its maximum displacement, that is, when the elastic potential energy of the second spring 404 reaches its maximum, the gravitational potential energy of the collar 401 can still overcome the elastic potential energy of the second spring 404 (that is, the collar 401 will not be lifted upward under the action of the second spring 404, and the upper surface of the collar 401 is always parallel to the bottom of the friction wheel 202).

[0060] Furthermore, as the height of the filter plate 320 increases, it exceeds the height of the collar 401, and the support legs 321 move upward, creating a gap between the bottom of the filter plate 320 and the collar 401 (i.e., the adjacent support legs 321 are exposed at this time, and the support legs 321 exceed the upper surface of the collar 401). This facilitates the discharge of impurities on the inclined surface from the gap when the ejector ring 310 moves upward later, thereby preventing the filter plate 320 from becoming clogged and ensuring the normal discharge of rainwater.

[0061] The following is combined with Figures 6-9 The specific structure of the top outlet is disclosed. The top outlet includes a baffle 301 and top rods 302 symmetrically arranged on both sides of the top of the baffle 301. The size of the baffle 301 is larger than the connection port of the branch pipe and the discharge pipe 120. The baffle 301 slides in the vertical groove opened in the inner wall of the discharge pipe 120. When discharging rainwater, the baffle 301 is closed. Conversely, when discharging impurities, the connection port is opened, thereby realizing the opening and closing of the connection port, so as to classify and discharge rainwater and impurities.

[0062] On the other hand, the push rod 302 passes through the slide rail 110, and its top end is inserted into the push-out ring 310. The push-out ring 310 is symmetrically embedded in the slide rail 110, and the inner side of the push-out ring 310 is a slope. Also, because the top center of the baffle 301 is connected to the iron block 311 embedded in the slide rail 110 by a pull rope, the iron block 311 is attracted to the magnet 211 at the bottom of the rotatably connected floating column 201 under normal conditions. Therefore, when the pull rope moves the baffle 301 upward, the push rod 302 pushes the ejector ring 310 upward, allowing impurities inside the ejector ring 310 to be discharged from the gap, preventing excessive accumulation of cleaned impurities inside the ejector ring 310. The top center of the baffle 301 is connected to the iron block 311 embedded in the slide rail 110 via the pull rope. Under normal conditions, the iron block 311 is attracted to the magnet 211 at the bottom of the rotatably connected floating column 201, causing blockage of the filter plate 320 and affecting the discharge of rainwater.

[0063] It should be noted that, due to the attraction between the iron block 311 and the magnet 211, when the louver body 100 is moved to both sides, the iron block 311 embeds into the slide rail 110. Furthermore, as the louver body 100 moves horizontally, the resistance experienced by the iron block 311 exceeds the attraction force between the iron block 311 and the magnet 211, causing the iron block 311 to separate from the magnet 211. Additionally, the bottom of the cavity within the frame of the slide rail 110 is a smooth surface, which restricts the rotation of the floating column 201, preventing its height from decreasing.

[0064] Secondly, to prevent discharged impurities from clogging the discharge pipe 120 and to achieve separate discharge of rainwater and impurities, the side of the baffle 301 away from the branch pipe is connected to a tilting filter plate 303 via a traction rope. The tilting filter plate 303 is located on the opposite side of the baffle 301 and is rotatably connected to the inner wall of the discharge pipe 120. Under the pull of the traction rope, the baffle 301 moves upward, opening the connection port. At the same time, the tilting filter plate 303 rotates clockwise. When the baffle 301 stops moving upward, the end of the tilting filter plate 303 away from the rotatable connection with the discharge pipe 120 flips into the connection port (and at this time, the tilting filter plate 303 is in an inclined state). The tilting filter plate 303 guides the cleaned impurities into the branch pipe, and rainwater flows through the tilting filter plate 303 and is discharged from the discharge pipe 120 into the drainage pipe, while impurities are discharged into the branch pipe. This achieves separate discharge of impurities and rainwater, thereby improving the urban environment.

[0065] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
