Abstract
Description
Technical Field
[0001] This utility model belongs to the field of casement window technology, specifically a concealed sash intelligent casement window. Background Technology
[0002] Casement windows are windows where the sash is connected to the frame via hinges and can be rotated to open. Casement windows have a gap relationship between the sash and the frame that combines embedding and overlapping. Both the frame and sash overlaps are equipped with elastic sealing strips, which provide superior sealing performance.
[0003] Currently, casement windows require profiles to ensure the stability and strength of the operable sashes, therefore the width of the profiles often cannot be too narrow. This causes the edges of the sash to create a large obstruction area in the field of vision, resulting in the sash blocking part of the window's light transmission area and reducing the amount of natural light entering the room. At the same time, thicker window edges make it easier for air to separate and vortex as it flows through the window, which increases airflow resistance.
[0004] Therefore, this application aims to reduce the area occupied by the fan material, thereby solving the problems of high airflow resistance and reduced light transmission area. Utility Model Content
[0005] The purpose of this application is to provide a concealed sash intelligent casement window, which aims to optimize the structure of the sash material, increase the light transmission area, and reduce air resistance.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0031] Please refer to the details. Figures 1-4As shown, a concealed-sash intelligent casement window includes a window sash 3, a window frame 1, and a hinge 2 connecting the window sash 3 and the window frame 1. The window sash 3 includes a sash material 31, a glass assembly 32, and a sealing gasket 33. The hinge 2 connects the sash material 31 to the window frame 1. The glass assembly 32 is connected to the hollow area of the sash material 31. The sealing gasket 33 is connected to the window frame 1 and is located at the overlap between the window frame 1 and the sash material 31. When the window sash 3 and the window frame 1 are closed, the sash material 31 and the window frame 1 combine to form a frame structure with a square cross-section. The window frame 1 is installed inside the wall, providing a foundation and support for the subsequent installation of the window sash 3. Hinges 2 are installed at both the top and bottom of the window sash 3, and the other end of the hinge 2 is connected to the window frame 1, thereby realizing the basic functions of opening and closing the window sash 3. The sash material 31 is designed as a multi-chamber profile structure. This design improves the thermal insulation and sound insulation performance of the sash 31. The sash 31 wraps around the outside of the glass assembly 32, which mainly consists of glass, window frame 1 or glazing strip, sealing strip, connecting parts, etc. These parts work together to ensure the optical performance and sealing performance of the window. The overlap is the contact area between the window sash 3 and the window frame 1, and the sealing performance is improved by installing a sealing gasket 33. Multiple overlaps can be provided between the window sash 3 and the window frame 1. From the cross-section, two overlaps are preferred to ensure the contact sealing between the window sash 3 and the window frame 1. In subsequent designs, multiple overlaps can also be provided to facilitate the window sash 3 abutting against the window frame 1, increasing the point of force and increasing the number of sealing layers.
[0032] Specifically, the sealing gasket 33 has a π-shaped cross-section, and its contact surface with the sash 31 is inclined, which facilitates the sash 31 pressing the sealing gasket 33 tightly onto the window frame 1, improving the structural sealing performance. The cross-section of the window frame 1 and the sash 3 are complementary, forming a square frame together. This reduces the original thickness of the window frame 1, significantly decreasing the size of the window edge. The window profile has a smaller visible size, and the sash 31 is hidden inside the cavity of the window frame 1, making it invisible from the inside. This results in a simple and aesthetically pleasing overall design, increasing the light transmission area. At the same time, the reduced thickness allows air to flow more smoothly across the window surface, reducing resistance caused by airflow separation and eddies, and also saving material costs.
[0033] like Figure 4 As shown, the inner edge of window frame 1 is inclined, with its opening facing outwards. Window frame 1 has a special gradient structure, with a larger opening area at the outdoor end and a smaller opening area at the indoor end, forming a shape that gradually tapers inwards. This can be achieved through special mold making or post-processing techniques. When outdoor wind blows towards the window at a certain angle, the larger outdoor opening area allows airflow to enter the window structure more smoothly. As window frame 1 gradually tapers inwards, more fresh outdoor air can enter the room under natural ventilation conditions, improving indoor air quality. At the same time, the larger outdoor opening area allows more natural light to enter the room, improving indoor lighting.
[0034] In this application, the cross-sections of the window frame 1 and the window sash 3 are both L-shaped or triangular, which facilitates the connection between the window frame 1 and the window sash 3 to form a square frame. The L-shape or triangle here is not an L-shape or triangle in the strict sense. For example, after the window frame 1 and the window sash 3 are closed, the closed areas of the two can extend to each other to optimize the connection structure and improve the rainproof and sound insulation effects.
[0035] like Figure 3 and Figure 5 As shown, a casement motor 21 is installed inside the window frame 1. The output end of the casement motor 21 is connected to the window sash 3 via a swing arm 22 to drive the window sash 3 to open or close. The casement motor 21 is installed inside the window frame 1, and its output end is connected to the swing arm 22, driving the window sash 3 to open and close. This allows for convenient intelligent or manual control of the casement motor 21 to achieve automatic opening and closing of the window sash 3 without manual operation. A slider 23 is connected to the end of the swing arm 22 away from the casement motor 21. The slider 23 is connected to the window sash 3 and is located on the side of the hinge 2 closer to the glass assembly 32. The sliding groove of the swing arm 22 connected to the casement motor 21 is offset from the groove of the hinge 2, so that the length of the hinge 2 is not reduced, ensuring the safety and reliability of the window and avoiding interference between the casement motor 21, the swing arm 22, and the hinge 2.
[0036] like Figure 2 and Figure 3 As shown, a locking component 6 is provided on the window frame 1. When the window sash 3 is closed to the window frame 1, the locking component 6 locks the window sash 3. When the casement motor 21 drives the window sash 3 to close on the window frame 1, the locking component 6 can directly extend into the edge of the window sash 3 through the pin or slider 23 to ensure that the window sash 3 cannot be opened and to ensure that it is in the closed state.
[0037] like Figure 3 , Figure 4 and Figure 6 As shown, in one embodiment of this application, the locking assembly 6 includes a telescopic unit 61 and a locking point 63. The locking point 63 is connected to the output end of the telescopic unit 61 and slides along the window frame 1. A lock seat 5 is installed on the window sash 3. When the telescopic unit 61 is opened, it moves the locking point 63 and extends it into the lock seat 5. The telescopic unit 61 can either extend the locking point 63 toward the lock seat 5 or retract the locking point 63 from the lock seat 5. By opening or closing the telescopic unit 61, the window sash 3 can be locked and fixed.
[0038] like Figure 3 , Figure 4 and Figure 6As shown, in one embodiment of this application, a transmission rod 62 is connected between the output end of the telescopic unit 61 and the locking point 63. The telescopic unit 61 drives the locking point 63 to move and extend into the lock seat 5 via the transmission rod 62. In this embodiment, the telescopic unit 61 can drive the transmission rod 62 to extend or retract, thereby adjusting the locking point 63 to move in or out of the lock seat 5 to realize the opening or closing of the window sash 3.
[0039] In addition to the two methods mentioned above, the output end of the telescopic unit 61 can also be directly inserted into the lock seat 5 on the window sash 3 in the horizontal direction to achieve the locking effect. The transmission rod 62 can increase the distance between the locking point 63 and the lock seat 5, ensuring that the locking position is at the upper and lower ends of the window sash 3, thereby improving the stability of the locking.
[0040] In the aforementioned telescopic unit 61, different implementation methods can be adopted, such as telescopic electric cylinders, telescopic air cylinders, or telescopic hydraulic cylinders. Other methods include using a locking hook and positioning lock bar, a locking motor, or electromagnet attraction. For example, if a locking hook and positioning lock bar are used, a positioning lock bar is installed on the window frame 1, and a locking hook is installed on the locking structure of the window sash 3. The locking hook engages with the positioning lock bar through the displacement of the window sash 3. The end of the hook's claw has a protrusion, and the inner side of the positioning lock bar's edge has a protrusion. The protrusion and the protrusion interlock to lock the window. If electromagnet attraction is used, a permanent magnet is installed on the window sash 3, and an electromagnet is installed on the window frame 1. When the window sash 3 is closed, the magnetic fields generated by the permanent magnet and the electromagnet attract each other, enhancing the locking force. When unlocking is required, the power supply to the electromagnet is cut off, the attraction of the permanent magnet weakens, and the window sash 3 can be easily opened; alternatively, both the permanent magnet and the electromagnet can be installed on the window frame 1, and the locking point 63 and the lock seat 5 can be locked together. The telescopic cylinder can also be directly inserted into the lock seat 5 of the window sash 3, which can also drive the locking point 63 and the lock seat 5 to lock together to achieve the locking effect.
[0041] like Figure 3 and Figure 6 As shown, in this application, a locking motor is preferably used. Specifically, the locking motor is installed inside the window frame 1, with both ends extending outwards. The transmission rod 62 is slidably placed in the groove of the window frame 1, with one end connected to the output end of the locking motor, facilitating the locking motor to drive the transmission rod 62 to extend outwards. When the transmission rod 62 extends, it drives the locking point 63 to move into the lock seat 5, as shown. Figure 6 As shown, this ensures that the window sash 3 and the window frame 1 are locked and fixed.
[0042] like Figure 3As shown, a handle 64 is rotatably mounted on the window frame 1, with one end of the handle 64 extending into the window frame 1 and connected to the telescopic unit 61. The shaft of the handle 64 is preferably square to ensure that the square-shaft handle 64 can cooperate with the locking motor, so that when the locking motor drives the transmission rod 62 to extend or retract, it can also drive the square-shaft handle 64 to rotate synchronously, facilitating subsequent manual adjustment and locking. A latch 11 is provided on the side wall of the window sash 3 near the locking assembly 6, which facilitates manual adjustment by the operator.
[0043] Conventional locking motors are located on window sash 3, resulting in long wiring distances for the locking motor. A wire guide is required between window sash 3 and window frame 1. The two ends of the wire guide are tightly connected to the corresponding connecting parts on window frame 1 and window sash 3, respectively. The wiring on one side of window frame 1 is connected to the wiring of the locking motor on window sash 3 through the connecting terminals of the wire guide, thereby realizing the power supply and control signal transmission of the locking motor. The square shaft handle 64, telescopic unit 61, transmission rod 62, locking point 63, and other transmission locking devices of this application are installed on window frame 1, which can solve the problem of complex wiring of telescopic unit 61.
[0044] like Figures 1-3 As shown, this application also includes a control panel 4, which is connected to the casement motor 21 and the telescopic unit 61. The control panel 4 is equipped with multiple buttons to drive the casement motor 21 and the telescopic unit 61 to work together to open or close the window sash 3.
[0045] Casement window electric operation principle:
[0046] To open the window: Press the open button on the control panel 4. The telescopic unit 61 drives the square shaft handle 64 to rotate 90° counterclockwise to the horizontal direction. At the same time, the telescopic unit 61 drives the locking point 63 on the transmission rod 62 to move. The locking point 63 disengages from the locking seat 5 on the window sash 3. Then, the casement motor 21 at the upper end of the window frame 1 drives the window sash 3 to open.
[0047] To close the window: Press the close button on the control panel 4. The casement motor 21 at the top of the window frame 1 will drive the window sash 3 to close. After the window sash 3 is closed, the telescopic unit 61 will drive the locking point 63 on the transmission rod 62 to move. At the same time, the telescopic unit 61 will drive the square shaft handle 64 to rotate 90° clockwise to the vertical direction. At this time, the locking point 63 will coincide with the locking seat 5 on the window sash 3, and the window will be closed.
[0048] Casement window manual operation principle:
[0049] To open the window: Rotate the handle 64 counterclockwise from the locked position, turning it 90° from the vertical direction to the horizontal direction. This will move the locking point 63 on the telescopic unit 61 and the transmission rod 62. At this time, the locking point 63 disengages from the locking seat 5 on the window sash 3, and then the window sash 3 can be manually pushed open.
[0050] To close the window: Manually pull the handle 11 on the window sash 3 to the fully closed position, rotate the handle 64 clockwise, turning it 90° from the horizontal direction to the vertical direction. This will cause the telescopic unit 61 and the locking point 63 on the transmission rod 62 to move. At this time, the locking point 63 coincides with the locking seat 5 on the window sash 3, and the window sash 3 is locked.
[0051] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
