Description

Technical Field

[0001] This invention relates to the field of solar energy doors and windows technology, specifically a low-carbon, energy-saving, air-purifying window. Background Technology

[0002] With increasing environmental awareness, low-carbon and energy-saving windows powered by solar energy are becoming more and more widely used. Building on this, various additional functions have been developed for windows powered by their own electricity, with air purification and environmental regulation being the most common. However, existing low-carbon and energy-saving air purification windows have the following problems in use:

[0003] The use of low-carbon, energy-saving air purification windows is often accompanied by various internal electronic devices that facilitate air purification and environmental regulation, such as negative ion generators, heating plates, and semiconductor cooling chips. Additionally, ventilation openings are required on the window frame for ventilation. However, existing low-carbon, energy-saving air purification windows do not conveniently close these openings when opening and closing the window. When the window sash is open, the increased airflow space and speed allow outside air to easily enter the ventilation space, potentially damaging internal electronic components. Furthermore, to protect these components during ventilation, filters are often installed. However, existing low-carbon, energy-saving air purification windows do not allow for automatic cleaning of the filters when the window sash is opened and closed; they typically require periodic manual disassembly and cleaning. This gradually reduces ventilation efficiency and is cumbersome, necessitating the design of specially designed disassembly and installation mechanisms, thus increasing costs.

[0004] To address the aforementioned issues, there is an urgent need for innovative designs based on existing low-carbon, energy-saving, and air-purifying windows. Summary of the Invention

[0005] The purpose of this invention is to provide a low-carbon, energy-saving, air-purifying window to solve the problems mentioned in the background art, such as the inconvenience of closing the ventilation opening when opening and closing the window, and the inconvenience of automatically cleaning the filter plate when the window sash is opened and closed. The technical solution of this invention addresses the problem that the existing technical solutions are too simplistic and provides a solution that is significantly different from the existing technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a low-carbon energy-saving air purification window, comprising a window frame, a window sash installed inside the window frame, and glass fixed inside the window sash, the glass being divided into inner and outer layers, the inner and outer layers being solar glass and one-way heat-conducting glass respectively, and a storage battery and a controller embedded in the window frame;

[0007] It also includes a mounting frame, which is embedded and fixed at the upper and lower ends of the window frame. A mounting bracket is fixed inside the mounting frame. A negative ion generator is provided at the front end of the mounting bracket, and a semiconductor cooler and a heating plate are respectively fixed at the front ends of the upper and lower mounting brackets. A motor is fixed at the rear end of the mounting bracket, and a fan is connected to the output end of the motor. Baffles are rotatably installed in the cavities at the front and rear ends of the mounting frame, and a filter plate is provided at the rear baffle. The filter plate is fixed to the inner wall of the mounting frame. Mounting strips are provided on both sides inside the mounting frame, and a transmission component is provided between the mounting strips and the rear baffle. The transmission component is used to drive the baffle to rotate. A cleaning component is provided between the mounting strips and the filter plate. The cleaning component is used to automatically clean the filter plate.

[0008] The movable column is fixed at both ends of the window sash and is located in a movable groove. The movable groove is opened on the inner wall of the window frame. A docking column is embedded and rotatably arranged between the movable groove and the window frame. The docking column is connected to a screw via a belt. The screw is embedded and rotatably arranged in the window frame. A movable rod is threaded on the screw and is fixedly connected to the mounting strip. A lifting assembly is provided between the movable column and the docking column. The lifting assembly is used to drive the mounting strip to move vertically according to the opening and closing of the window sash.

[0009] Preferably, the transmission assembly includes a rack, which is fixed to the end of the mounting strip, and one end of the rack is engaged with a gear one, and one side of the gear one is engaged with a gear two. Both the gear two and the gear one are embedded and rotatably disposed within the mounting frame, and the gear two is connected to the baffle.

[0010] Preferably, the cleaning assembly includes a cleaning frame, which is fixed between two mounting strips. A mounting plate is connected to the cleaning frame via a spring, and a mounting head is slidably disposed within the mounting plate. A brush is fixed to the rear end of the mounting head, and a second spring is disposed between the brush and the mounting plate. A guide strip is fixed to the inner wall of the cleaning frame, and an end strip is disposed between the interior of the cleaning frame and the end of the mounting plate. The end strip is fixed to the inner wall of the mounting frame, and a guide block is fixed to the inner side of the end strip.

[0011] Preferably, the mounting heads are evenly distributed on the mounting plate, and the mounting heads contact the guide strip after movement, and the contact position between the guide strip and the mounting head is designed as a bevel structure.

[0012] Preferably, the guide block is designed as a hemispherical structure that contacts the end of the mounting plate, and the mounting plate slides laterally elastically within the cleaning frame by a spring. The guide blocks are evenly distributed on the end strips, and the guide blocks on the two end strips are staggered.

[0013] Preferably, the screw drives the mounting strip to move vertically within the mounting frame via a movable rod, and the moving distance of the mounting strip is greater than the width of the filter plate.

[0014] Preferably, the lifting assembly includes a base column, which is fixed on a movable column. A guide sleeve is fitted on the base column and connected to the movable column via an elastic telescopic rod. A positioning rod is fixed on the guide sleeve, with one end of the positioning rod inserted into a positioning block, which is fixed on the base column. The positioning block is embedded in the cavity inside the docking column. A push bar is provided on the movement trajectory of the guide sleeve and is fixed to the inner wall of the movable groove.

[0015] Preferably, the guide sleeve is designed as a frustum-shaped structure, and the top inclined surface of the guide sleeve is at the same horizontal plane as the bottom of the push bar.

[0016] Preferably, the top view of the positioning block is designed as a rectangular structure that fits into the cavity inside the docking column, and the positioning block slides in close contact within the movable groove.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. This invention includes a lifting assembly. When the window is opened, the window sash rotates, which drives the docking column to rotate via the positioning block. This, in turn, causes the movable rod and mounting strip to move vertically. Furthermore, the transmission assembly drives the baffle to rotate, sealing the front and rear cavities of the mounting frame. This prevents external air from entering the interior through natural wind guided by the window sash when the window is opened. Then, under the action of the guide sleeve and push strip, the window sash can move and rotate freely without affecting the internal transmission. Simultaneously, when the window is closed, the positioning rod automatically inserts into the positioning block through normal operation of the window sash. This allows the mounting strip to move in the reverse direction again when the window is finally closed, causing the baffle to rotate and open, facilitating indoor and outdoor ventilation and subsequent heating and cooling operations.

[0019] 2. This invention, based on the free opening and closing of the window sash, filters the outside air by setting up a filter plate. During the opening and closing of the window, which drives the vertical movement of the mounting strip, the cleaning frame can also move vertically, the mounting plate moves vertically and horizontally synchronously, and the brush moves vertically, horizontally, and vertically. The filter plate can be cleaned during each opening and closing of the window, which not only prevents clogging but also improves the filtration effect. At the same time, the whole process requires no additional operation or disassembly for cleaning. It is based on the simple opening and closing of the window and has high practicality.

A negative ion generator 8 is set at the front end of the mounting bracket 7, and a semiconductor cooler and a heating plate are respectively fixed at the front ends of the upper and lower mounting brackets 7. A motor 9 is fixed at the rear end of the mounting bracket 7, and a fan 10 is connected to the output end of the motor 9. Baffles 11 are rotatably installed in the cavities at the front and rear ends of the mounting frame 6, and a filter plate 111 is set at the rear baffle 11. The filter plate 111 is fixed to the inner wall of the mounting frame 6. The two sides inside the mounting frame 6 are provided with An installation strip 12 is provided, and a transmission component 13 is provided between the installation strip 12 and the rear baffle 11. The transmission component 13 is used to drive the baffle 11 to rotate. The movable column 15 is fixed at the upper and lower ends of the window sash 2, and the movable column 15 is located in the movable groove 16. The movable groove 16 is opened on the inner wall of the window frame 1. A docking column 17 is embedded and rotatably provided between the movable groove 16 and the window frame 1. The docking column 17 is connected to a screw 18 by a belt. The screw 18 is embedded and rotatably provided in the window frame 1. A movable rod 19 is threaded on the screw 18. The movable rod 19 is fixedly connected to the installation strip 12. A lifting component 20 is provided between the movable column 15 and the docking column 17. The lifting component 20 is used to drive the installation strip 12 to move vertically according to the opening and closing of the window sash 2.

[0032] The transmission assembly 13 includes a rack 131, which is fixed to the end of the mounting strip 12. One end of the rack 131 is meshed with a gear 132, and one side of the gear 132 is meshed with a gear 133. Both gear 133 and gear 132 are embedded and rotatably mounted in the mounting frame 6, and gear 133 is connected to the baffle 11. The screw 18 drives the mounting strip 12 to move vertically within the mounting frame 6 via the movable rod 19, and the movement distance of the mounting strip 12 is greater than the width of the filter plate 111. The lifting assembly 20 includes a base column 201, which is fixed to the movable column 15. A guide sleeve 202 is fitted on the base column 201, and the guide sleeve 202 is elastically extended. The retractable rod 203 is connected to the movable column 15. A positioning rod 204 is fixed on the guide sleeve 202, and one end of the positioning rod 204 is inserted into the positioning block 205. The positioning block 205 is fixed on the bottom column 201 and embedded in the internal cavity of the docking column 17.

The positioning block 205 slides in contact with the movable groove 16.

[0033] When the window sash 2 is opened, the movable column 15 drives the docking column 17 to rotate, which in turn drives the mounting strip 12 to move vertically. Through the transmission component 13, the baffle 11 rotates, sealing the space in front and behind the mounting frame 6 to prevent external dust and other impurities from entering the interior. At the same time, when the window sash 2 is closed, the baffle 11 rotates in the opposite direction, opening the space in front and behind the mounting frame 6 for ventilation.

[0034] Example 2: Based on Example 1, please refer to... Figures 1-8 A cleaning assembly 14 is provided between the mounting strip 12 and the filter plate 111, and the cleaning assembly 14 is used to automatically clean the filter plate 111. The cleaning assembly 14 includes a cleaning frame 141, which is fixed between the two mounting strips 12. A mounting plate 143 is connected to the cleaning frame 141 by a spring 142. A mounting head 144 is slidably provided in the mounting plate 143. A brush 145 is fixed to the rear end of the mounting head 144. A spring 146 is provided between the brush 145 and the mounting plate 143. A guide strip 147 is fixed on the inner wall of the cleaning frame 141. An end strip 148 is provided between the inside of the cleaning frame 141 and the end of the mounting plate 143. The end strip 148 is fixed on the inner wall of the mounting frame 6. A guide block 149 is fixed on the inner side of the end strip 148.

[0035] Mounting heads 144 are evenly spaced on mounting plate 143, and after moving, mounting heads 144 contact guide strips 147. The contact point between guide strips 147 and mounting heads 144 is designed as a beveled structure. Guide blocks 149 are designed as hemispherical structures that contact the end of mounting plate 143. Mounting plate 143 slides laterally elastically within cleaning frame 141 via spring 142. Guide blocks 149 are evenly spaced on end strips 148, and the guide blocks 149 on the two end strips 148 are staggered.

[0036] When the window sash 2 is opened and closed, the vertical movement of the mounting strip 12 can drive the cleaning frame 141 to move vertically, which can drive the brush 145 to move horizontally and vertically in sync, so as to automatically clean the filter plate 111.

[0037] Working principle: When using this low-carbon, energy-saving air purification window, such as Figures 1-8 First, the user rotates the window sash 2, which causes the movable column 15 to rotate within the movable groove 16, thus opening the window. During this process, the movable column 15 drives the positioning block 205 to rotate via the guide sleeve 202 and the positioning rod 204, which in turn drives the docking column 17 to rotate. The docking column 17 drives the screw 18 to rotate via a belt, which in turn drives the movable rod 19 and the mounting strip 12 to move vertically. The mounting strip 12 drives the baffle 11 to rotate via the rack 131, gear 132, and gear 133, causing the baffle 11 to close the front and rear cavities of the mounting frame 6, preventing the window sash 2 from opening. When the system is started, external air enters the interior of the mounting frame 6. Furthermore, the vertical movement of the mounting strip 12 can drive the cleaning frame 141 to move vertically. Through the contact between the mounting plate 143 and the guide block 149, and with the help of spring 142, the mounting plate 143 can move laterally back and forth when it moves vertically. When the mounting plate 143 moves laterally, the mounting head 144 contacts the inclined surface of the guide strip 147. With the help of spring 146, the mounting head 144 can move longitudinally synchronously, thereby enabling the brush 145 to move synchronously vertically, laterally, and longitudinally to clean the filter plate 111.

[0038] After the window sash 2 is opened, the user can move the window sash 2 laterally, causing the movable column 15 to move within the movable groove 16. When the guide sleeve 202 moves to the push bar 206, the guide sleeve 202 is forced downward, causing the positioning rod 204 to separate from the positioning block 205. At this time, the positions of the movable column 15 and the positioning rod 204 are released, and the user can rotate the window sash 2 freely while moving it, adjusting the position and angle of the window sash 2 according to their own preferences. When closing the window, the window sash 2 is moved back to its original position, at which point the positioning block 205 re-enters the bottom cavity of the docking column 17, and the guide sleeve is moved back to its original position under the action of the elastic telescopic rod 203. 202 and positioning rod 204 are reset. At this time, rotate window sash 2 so that positioning rod 204 automatically inserts into the bottom of positioning block 205 to complete the locking again. Then rotate window sash 2 in reverse to close it completely. At the same time, the screw 18 is driven to rotate in reverse through docking column 17, and mounting strip 12 is reset so that baffle 11 is in the open state. At the same time, the filter plate 111 is cleaned again by brush 145. Then, the operation of components such as motor 9, negative ion generator 8, heating plate and semiconductor cooling chip at the upper and lower positions can be controlled by controller 5 to perform cooling or heating operations in the room.
