[0002] High-rise office buildings usually adopt glass curtain walls to ensure indoor light transmission and enhance the beauty of urban high-rise buildings. Existing high-rise glass curtain walls generally have poor ventilation problems, which in turn lead to low air quality in the office. Installing a ventilation device on the glass curtain wall is one of the important means to improve indoor air quality. The ventilation device can discharge the indoor dirty air and supplement the indoor with fresh outdoor air. While solving the problem of improving air quality, the ventilation device brings new problems: the overall integrity of the ventilation device and the glass curtain wall is poor, resulting in a low safety factor for the opening and closing of the ventilation device, and also affecting the overall appearance of the building. In addition, the ventilation device is installed and exposed in the air. During the long-term ventilation use process, the ventilation holes will be blocked by fluff and accumulated dust, which in turn affects the ventilation effect. Since the ventilation device belongs to a high-altitude building, the cleaning risk factor is high and the cleaning cost is high, increasing the maintenance cost of the ventilation device.

[0045] As Figures 1 - 7 shown, the present invention provides a concealed ventilation window sill system, which includes:

[0046] An outdoor curtain wall structure, which includes a metal frame and a glass curtain wall 2 and a perforated plate 3 filled in the metal frame;

[0047] An indoor window sill structure, which includes a window sill vertical plate 41 and a window sill panel 42 connected to the metal frame, and a ventilation mechanism 5 is provided between the window sill panel 42 and the frame;

[0048] A water guide plate 6, which is provided between the outdoor curtain wall structure and the indoor window sill structure. One side of the water guide plate 6 is connected to the window sill vertical plate, and the other side extends obliquely downward towards the direction close to the perforated plate 3.

[0049] In the above technical solution, the present invention provides a concealed ventilation window sill system, which sets the ventilation mechanism on the window sill panel and cooperates with the perforated plate. On the premise of ensuring the safety of the ventilation mechanism opening and the elevation effect, the ventilation mechanism is set as a concealed type, which improves the safety of the ventilation mechanism opening, integrates the indoor window sill decoration, and improves the aesthetics of the high-rise curtain wall.

[0050] The metal frame, the glass curtain wall and the perforated plate form an integral curtain wall structure. The glass curtain wall ensures the indoor light transmittance, and the perforated plate ensures the indoor ventilation and improves the indoor air quality; the lower part of the window sill vertical plate is supported on the ground, and the connection between the window sill panel and the frame makes the indoor curtain wall structure and the indoor window sill structure form a whole; As Figure 1 shown, the window sill system of the present invention is composed of multiple units. Specifically, each room corresponds to one unit, and the frames of multiple units are connected to each other. Each unit is correspondingly provided with a perforated plate and a window sill structure. The window sill panel is located above the perforated plate, and a ventilation mechanism is provided between the window sill panel and the frame. Outdoor air enters between the window sill structure and the curtain wall structure through the perforated plate, and then enters the room through the ventilation mechanism, realizing the replacement of indoor air and ensuring the indoor air quality; specifically, each unit is correspondingly provided with a water guide plate, and the water guide plate is provided between the window sill vertical plate and the perforated plate and is located below the window sill panel. The water guide plate drains the rainwater that enters between the window sill structure and the curtain wall structure through the perforated plate downward to the perforated plate and discharges it through the perforated plate.

[0051] The high-rise curtain wall provided by the present invention has high safety and aesthetics, realizes a flat exterior facade of the building without windows (hidden opening), and realizes the ventilation function through the ventilation mechanism. It has better waterproof and heat insulation performance than the exposed windows, and can greatly improve the safety of personnel and property without the need for exposed window limiters. Further, the integrated design of the indoor window sill reduces the secondary decoration of the indoor window sill.

[0052] In another technical solution, for the hidden ventilation window sill system, the ventilation mechanism is a flip-type natural ventilator. The ventilator sold on the market is installed between the window sill panel and the frame using conventional techniques. When ventilation is required, the ventilator is opened, and when ventilation is not required, the ventilator is closed.

[0053] In another technical solution, for the hidden ventilation window sill system, the ventilation mechanism between the window sill panel 42 and the frame is an openable and closable ventilation window. The ventilation window is installed between the window sill panel and the frame. When ventilation is required, the ventilation window is opened, and when ventilation is not required, the ventilation window is closed.

[0054] In another technical solution, for the hidden ventilation window sill system, the window sill panel 42 is an aluminum plate or a stone plate. The appropriate material is selected to make the window sill panel according to specific requirements.

[0055] In another technical solution, for the hidden ventilation window sill system, heat-insulating rock wool 43 is laid on the inner side surface of the window sill vertical board. The setting of the heat-insulating rock wool improves the heat insulation performance.

[0056] In another technical solution, for the hidden ventilation window sill system, the metal frame includes a plurality of vertically arranged aluminum columns 11 and horizontally arranged aluminum crossbeams 12 connecting the aluminum columns.

[0057] In another technical solution, for the hidden ventilation window sill system, it further includes a cleaning mechanism, which includes:

[0058] A water storage tank 71, which is arranged below the water guide plate 6 (connected to the frame). The bottom of the water storage tank 71 is provided with a sewage outlet, and a baffle is arranged on it;

[0059] Two water diversion plates 72, which are respectively arranged at the two sides of the top of the water storage tank 71. The lower end of each water diversion plate 72 is connected to the water storage tank 71, and the upper end extends obliquely upward in a direction away from the center of the water storage tank 71; One of the water diversion plates close to the window sill vertical board 41 is parallel to the water guide plate 6 and the upper part of this water diversion plate overlaps with the lower part of the water guide plate 6; The upper end of the other water diversion plate close to the perforated plate 3 is located below the perforated plate 3 and is adjacent to the perforated plate 3. A plurality of protrusions 721 are arranged on the inner side surface of the other water diversion plate;

[0060] A water filter tank 73 is provided inside the water storage tank 71. Water filter holes are provided on the upper side wall of the water filter tank 73; an overflow port communicating with the outside is provided at the top of one side of the water filter tank 73.

[0061] A moving rod 74 is horizontally provided inside the perforated plate 3. The moving rod 74 is parallel to the perforated plate 3. A slider 741 is rotatably connected to each end of the moving rod 74. Each slider 741 is slidably connected to the frame in the vertical direction; the inside of the moving rod 74 is hollow, and one end of the moving rod 74 is rotatably and sealingly connected with a cover plate.

[0062] A water guide pipe, one end of which is located inside the moving rod 74 and the other end passes through the middle of the cover plate and communicates with the water filter tank 73; a water pump is provided on the water guide pipe; the water guide pipe is arranged by using conventional technical means to connect the internal cavity of the moving rod 74 with the inside of the water filter tank 73, and then the water inside the water filter tank 73 is conveyed into the moving rod 74; the setting of the cover plate can ensure the sealing of the internal cavity of the moving rod without water leakage, and at the same time enable the water guide pipe not to interfere with the rotation of the moving rod around its own axis.

[0063] A plurality of spray heads 75 are arranged at intervals along the length direction of the moving rod 74 on the side of the moving rod 74 close to the perforated plate 3. Each spray head 75 communicates with the inside of the moving rod 74; the spray heads 75 spray water towards the perforated plate 3, and the water pressure can wash away the dirt on the perforated plate 3.

[0064] A cleaning brush 76 is provided on the side of the moving rod 74 close to the perforated plate 3 and above the plurality of spray heads 75. The bristles of the cleaning brush 76 can be inserted into the through holes of the perforated plate 3.

[0065] In the above technical solution, the present invention provides a cleaning mechanism for the perforated plate, which can regularly clean the perforated plate, ensure the ventilation effect, eliminate the need for manual high-altitude cleaning operations, reduce the cleaning cost, and reduce the maintenance cost of the window sill system.

[0066] In the above technical solution, a water storage tank with an open top is provided to collect rainwater and the cleaning water left after cleaning the perforated plate. The water in the water storage tank is filtered through the water filter holes and enters the water filter tank. The remaining sewage in the water storage tank can be discharged through the sewage outlet; a water diversion plate is respectively arranged at the top of both sides of the water storage tank, which can quickly collect the rainwater on the water diversion plate into the water storage tank, and can also collect the cleaning water flowing downward from the flushing of the perforated plate into the water storage tank, realizing the reuse of water resources. In practical applications, in order to ensure the normal progress of the cleaning operation, the water storage tank can be connected to the indoor water source (water faucet). In the weather without rain, the indoor water source is used to supply water to the water storage tank, and then the cleaning of the perforated plate is realized.

[0067] Water in the filter water tank is conveyed to the inside of the movable rod through a water pump, thereby supplying water to the nozzle. A high-pressure nozzle is selected for the nozzle to enhance the impact force of water spraying and improve the cleaning effect. After the nozzle sprays water for cleaning, the cleaning brush scrapes the perforated plate again, which can remove impurities adhering to the through holes of the perforated plate and ensure the ventilation of the perforated plate. At the same time, the slider moves up and down relative to the frame, driving the movable rod to move up and down to clean the entire perforated plate. The reciprocating up and down movement of the movable rod can achieve a more thorough cleaning of the perforated plate. Further, the movable rod can be moved to the lower limit position, and the movable rod is rotated around its axis, driving the nozzle and the cleaning brush to rotate downward. The protrusion on the other water diversion plate can scrape the cleaning brush to remove the sundries adhering to the cleaning brush, thereby ensuring the cleaning effect of the cleaning brush. For details, please refer to the appendix Figure 6 and Figure 7 , the movable rod rotates forward and backward reciprocally, driving the rotation of the cleaning brush;

[0068] The up and down movement of the two sliders 741 is driven by a driving mechanism. The driving mechanism includes: two vertically arranged rotating shafts 91 respectively arranged at both ends of the movable rod. Each rotating shaft is rotatably arranged on the column. A threaded sleeve is rotatably sleeved on the rotating shaft 91 (the rotation of the rotating shaft drives the up and down movement of the threaded sleeve). The slider is slidably connected to the column in the vertical direction and fixedly connected to one side of the threaded sleeve. The movable rod is rotatably connected to one side of the two sliders through a rotating bearing (the up and down movement of the slider drives the up and down movement of the movable rod, and at the same time the movable rod can rotate relative to the slider around its own axis). One end of one of the rotating shafts is connected to the output shaft of the first motor 92. The two rotating shafts 91 are connected by a transmission belt 93 (the first motor drives one of the rotating shafts to rotate and drives the rotation of the other rotating shaft through the transmission belt, realizing the synchronous and same-direction rotation of the two rotating shafts, thereby driving the synchronous and same-direction up and down movement of the two threaded sleeves, driving the synchronous and same-direction up and down movement of the two sliders, and thus driving the up and down movement of the movable rod while keeping it horizontal). One end of the movable rod is connected to the output shaft of the second motor (the second motor drives the movable rod to rotate around its own axis).

[0069] In another technical solution, for the hidden ventilation window sill system, the filter water tank is of a cubic structure; the cleaning mechanism further includes:

[0070] A plurality of movable rods 81 are arranged on the other water diversion plate and are perpendicular to the water diversion plate. The bottom of each movable rod 81 is slidably connected to the water diversion plate. One side of each movable rod is connected to the frame through a first spring 82; the height of the movable rod 81 is greater than the height of the protrusion. When the movable rod moves to the lower limit position and rotates around its own axis, it can drive the movable rod to move obliquely downward;

[0071] A housing, which includes four scraping mesh plates 83 corresponding to the four side faces of the water filtering tank. On the inner side of each mesh plate, there are bristles inserted into the water filtering holes on the water filtering tank. The top of the mesh plate is connected to the top of the water filtering tank through a vertically arranged second spring 84; the four mesh plates form an integral housing;

[0072] Multiple fixed pulleys 86, which are arranged on the inner wall of the water storage tank;

[0073] Multiple first rope bodies 85, with one first rope body corresponding to one movable rod. One end of each first rope body is connected to the movable rod, and the other end passes through multiple fixed pulleys in sequence and is connected to the housing;

[0074] A second rope body 88, one end of which is connected to the housing and the other end is connected to the baffle 87.

[0075] In the above technical solution, the present invention further provides a housing for cleaning the water filtering holes of the water filtering tank, on which there are bristles that can scrape the water filtering holes. Through the cooperation of the movable rod, the first spring, the first rope body, the fixed pulley and the second spring, the cleaning brush can be driven to move up and down while cleaning, so as to realize the cleaning of the water filtering holes, ensure the normal filtration of the water in the water storage tank, ensure the normal supply of clean filtered water to the movable rod, and thus ensure the normal cleaning operation of the perforated plate;

[0076] Both the first spring and the second spring are tension springs. The settings of the first spring and the second spring are as follows: when the movable rod is above another water diversion plate, the movable rod is in the upper limit position, the mesh plate is in the lower limit position and is below the water filtering holes on the water filtering tank, and the baffle is at the bottom of the water storage tank and blocks the sewage outlet; when the movable rod moves to the lower limit position and rotates around its own axis, the nozzle drives the movable rod to move obliquely downward, the first spring is stretched, the movement of the movable rod drives the first rope body to move, and under the elastic force of the second spring, the mesh plate moves upward. The upward movement of the mesh plate drives the second rope body to move upward, and then drives the baffle to move upward, and the sewage outlet is opened, and the sewage in the water storage tank can be discharged; when the movable rod is rotated in the reverse direction, the nozzle releases the driving force on the movable rod, and under the elastic force of the first spring, the movable rod moves obliquely upward and returns to its original position, and drives the first rope body to move and then drives the mesh plate to move downward to below the water filtering holes. When the mesh plate moves downward, the baffle moves downward under its own gravity and blocks the sewage outlet again. Counterweights are provided on both the baffle and the mesh plate to offset the buoyancy of water.

[0077] Specifically, as Figures 6 - 7 shown, the rotation of the movable rod drives the nozzle and the cleaning brush to move downward. The nozzle drives the movable rod to move obliquely downward. Under the action of the first spring, the first rope body and the second spring, the downward movement of the movable rod drives the upward movement of the mesh plate. The reciprocating forward and reverse rotation of the movable rod drives the up and down movement of the mesh plate. While the mesh plate moves up and down, it drives the bristles to scrape the water filtering holes back and forth, and the dirt in the water filtering holes can be removed;

[0078] Furthermore, the up and down movement of the baffle can be driven by the second rope body. When the net plate moves upward, it drives the baffle to move upward to open the sewage outlet at the bottom of the water storage tank, discharging the sewage at the bottom of the water storage tank. When the net plate moves downward, under the action of the gravity of the baffle, it moves downward to block the sewage outlet again.

[0079] The equipment quantity and treatment scale described here are used to simplify the description of the present invention. The application, modification and variation of the present invention are obvious to those skilled in the art.

[0080] Although the embodiments of the present invention have been disclosed as above, it is not limited to the applications listed in the specification and embodiments. It can be fully applied to various fields suitable for the present invention. For those familiar with the field, additional modifications can be easily achieved. Therefore, without departing from the general concept defined by the claims and the equivalent scope, the present invention is not limited to the specific details and the illustrated examples here.
