Some exemplary embodiments of the present application have been described for illustrative purposes, and it is to be understood that the present application may be embodied in other ways not specifically shown in the drawings.

As shown in fig. 1-4, the window assembly of the present application for installation in a basement includes an outer frame assembly 1, an inner frame assembly 2, and a glass 3. Outer frame assembly 1 defines an outer frame assembly opening in which inner frame assembly 2 is disposed. The inner frame assembly 2 defines an inner frame opening in which the glass 3 is disposed and is connected to the inner frame assembly 2. In the example of the present application, the outer frame member opening is rectangular. The inner frame assembly 2 and the glass 3 can move relative to the outer frame assembly 1, thereby realizing the smoke exhausting and ventilating requirements of the basement.

As shown in fig. 1 to 4, the casing assembly 1 includes a top plate 11, a bottom plate 12, an outer sidewall 13 and an inner sidewall 14. The top plate 11 and the bottom plate 12 are arranged in a horizontal direction, and are substantially annular plates. The top plate 11 and the bottom plate 12 have hollow portions for defining the outline frame assembly opening. The outer side wall 13 is also an annular plate, but it is formed extending in the vertical direction. The outer side wall 13 is disposed between the top plate 11 and the bottom plate 12. More specifically, the top of the outer sidewall 13 is connected to the top plate 11 at a position close to and at a distance from the opening of the casing assembly. The bottom of the outer side wall 13 is connected to the bottom plate 12 at a connection point close to the opening of the casing assembly and at a distance from the opening of the casing assembly. The top plate 11, the bottom plate 12 and the outer side wall 13 generally form a U-shape that is open laterally and in which the top wall 4 of the basement (e.g., soil, cement slab, etc.) is received, so that the external frame assembly 1 is connected to the top wall 4 of the basement by means of connecting members (e.g., bolts, etc.). The inner side wall 14 is an annular plate that is formed to extend in the vertical direction. An inner sidewall 14 is disposed between the top plate 11 and the bottom plate 12, and a bottom of the inner sidewall 14 is connected to the bottom plate 12. More specifically, the junction of the bottom of the inner sidewall 14 and the bottom plate 12 is disposed adjacent to the opening of the casing assembly. The top of inner sidewall 14 is adapted to mate with inner frame member 2.

As shown in fig. 2 and 3, the top plate 11, the bottom plate 12, the outer sidewall 13 and the inner sidewall 14 enclose a cavity 5. The cavity 5 is a substantially annular cavity arranged in a horizontal direction and surrounds the inner side wall 14. Wherein a portion of the top panel 11 forms a cavity top wall 51, a portion of the bottom panel 12 forms a cavity bottom wall 52, the inner sidewall 14 forms a cavity inner wall, and the outer sidewall 13 forms a cavity outer wall. A chamber opening is formed between the chamber inner wall and the chamber top wall 51. A communication pipe 63 is provided in the bottom plate 12, which is in fluid communication with the chamber 5 and is connected to a drainage system (not shown) of the basement.

As shown in fig. 2 and 3, the inner frame assembly 2 includes an inner frame body 21 and an inner frame support mechanism 22. The inner frame body 21 includes a circumferential portion 211 and an inner frame body bottom portion 212. The circumferential portion 211 is a substantially annular plate that is formed to extend in the vertical direction. The peripheral portion 211 forms an inner frame opening to receive the glass 3. The inner frame body bottom 212 is arranged in a horizontal direction, and is a substantially annular plate. The inner frame body bottom 212 has an inner frame hollow. The bottom of the circumferential portion 211 is connected to the outer periphery of the inner frame body bottom 212 such that the circumferential portion 211 and the inner frame body bottom 212 are substantially L-shaped in vertical section. The inner frame body bottom 212 abuts against the bottom of the outer edge of the glass 3 to carry the glass 3, and since the inner frame body bottom 212 has an inner frame hollow portion, sunlight is not affected to shine into the basement through the glass 3. The inner frame support mechanism 22 is arranged in the vertical direction and is substantially annular. The inner frame support mechanism 22 is provided at a lower portion of the inner frame body bottom 212 and is connected to the inner frame body bottom 212, thereby supporting the inner frame body 21 and the glass 3.

As shown in fig. 2 and 3, when the inner frame assembly 2 and the outer frame assembly 1 are mounted in place, the top of the inner frame assembly 2 is disposed at substantially the same height as the top of the outer frame assembly 1. An opening gap 61 is provided between the circumferential portion 211 of the inner frame member 2 and the outer frame member opening of the outer frame member 1, and is communicated with the cavity 5. The opening gap 61 is generally annular and surrounds a circumferential portion 211 of the inner frame assembly 2. The opening gap 61 extends substantially in the vertical direction. For example, in rainy days, rainwater can flow into the cavity 5 through the opening gap 61, so that the rainwater is accumulated in the cavity 5. The rainwater accumulated in the receiving chamber 5 can be discharged out of the receiving chamber 5 through the communication pipe 63 at the bottom of the receiving chamber 5.

In the following, rain is used as an example, but it will be understood by a person skilled in the art that the window assembly of the present application is not only suitable for use in rain, but that it will also achieve the same effect when other liquids impact the window assembly.

As shown in fig. 2 and 3, the window assembly further includes an extension wall 55. Extension wall 55 is formed extending from chamber top wall 51 in a generally horizontal direction toward inner frame member 2 such that extension wall 55 forms a tortuous channel 62 with inner frame member 2. The meandering channel 62 is arranged at an angle with respect to the opening gap 61. Specifically, the opening gap 61 extends generally vertically, while the tortuous passage 62 extends generally horizontally, which is generally at 90 °. It will be appreciated that in other embodiments, the opening gap 61 and the tortuous path 62 may be disposed at other angles. The tortuous passage 62 is provided between the open gap 61 and the receptacle 5 and is in fluid communication with the open gap 61 and the receptacle 5.

As shown in fig. 2 and 3, the window assembly further comprises a sealing mechanism and an additional seal 73 in order to minimize the flow of rain into the cavity 5 through the opening gap 61. The sealing mechanism is disposed in the opening gap 61. An additional seal 73 is provided in the meandering channel 62. Specifically, the sealing mechanism includes a first seal 71 and a second seal 72. Wherein the first seal 71 is arranged substantially at the top of the opening gap 61. Specifically, the first seal 71 has a fixed end and a free end. The fixed end of the first seal member 71 is connected to the top of the outer edge side of the circumferential portion 211 of the inner frame member 2, and the free end of the first seal member 71 contacts and abuts against the top of the inner edge side of the top plate 11 of the outer frame member 1. The first seal 71 is disposed substantially in the horizontal direction so as to be able to block most of the rainwater outside the opening gap 61 when it is impacted by the rainwater. As one example, the first seal 71 can block approximately 80% of rain water falling on the first seal 71. The second seal 72 is arranged approximately in the middle of the opening gap 61. Specifically, the second seal 72 has a fixed end and a free end. The fixed end of the second sealing member 72 is connected to the middle portion of the inner edge side of the top plate 11 of the outer frame member 1, and the free end of the second sealing member 72 contacts and abuts against the middle portion of the outer edge side of the circumferential portion 211 of the inner frame member 2. Thereby, the first seal 71 and the second seal 72 can form two layers of seals with opposite directions of the free ends, so that rainwater can be blocked by the second seal 72 after penetrating downwards through the first seal 71. Similarly, the additional seal 73 has a fixed end and a free end. The fixed end of the additional seal 73 is connected to the top of the extension wall 55 and the free end of the additional seal 73 contacts and abuts the bottom of the inner frame body bottom 212 of the inner frame assembly 2. Since the fixed end of the additional sealing member 73 is disposed at the bottom thereof and the free end is disposed at the top thereof, the bottom of the opening gap 61 can form a temporary accommodation area. When rainwater penetrates downward through the first and

second seals

71 and 72, rainwater can be accumulated in the temporary accommodation area. After the amount of rainwater accumulated in the temporary accommodation area increases, the rainwater falls into the receiving cavity 5 through a gap between the free end of the additional sealing member 73 and the bottom 212 of the inner frame body.

As shown in fig. 2, the window assembly further comprises a power means 81, a water level indicating means 82 and a control means (not shown). Wherein the power device 81 and the water level indicating device 82 are disposed in the cavity 5. The power device 81 is used for providing power for the rainwater contained in the cavity 5 to drain out of the cavity 5. As one example, the power device 81 is a water pump. The water level indicating means 82 is used to detect the level of rain water in the chamber 5. As an example, the water level indicating device 82 is a float ball. The power device 81, the water level indicating device 82 and the control device are in communication connection. When the water level indicating means 82 detects that the current water level is higher than the threshold maximum water level, the water level indicating means 82 sends a first water level signal to the control means, and in response to the first water level signal, the control means activates the power means 81. When the water level indicating means 82 detects that the current water level is below the threshold minimum level, the water level indicating means 82 sends a second water level signal to the control means, and in response to this second water level signal, the control means turns off the power means 81.

With continued reference to fig. 2 and 3, because the inner frame assembly 2 is capable of movement relative to the outer frame assembly 1 in the present application, an inner channel 9 is formed between the bottom of the inner frame support mechanism 22 of the inner frame assembly 2 and the top of the inner side wall 14 of the outer frame assembly 1. The inner passage 9 is capable of communicating the chamber 5 with the basement interior space (not shown). In order to prevent moisture or rain water in the cavity 5 from entering the basement interior space, an inner channel seal 91 is provided in the inner channel 9. Inner channel seal 91 has a fixed end and a free end. The fixed end of inner channel seal 91 is attached to the top of inner sidewall 14 and the free end of inner channel seal 91 contacts and abuts the bottom of inner frame support mechanism 22.

In the example of the present application, the first seal 71 and the second seal 72 are substantially flat in cross-section, while the additional seal 73 and the inner channel seal 91 are substantially semi-circular in cross-section. It will be appreciated by those skilled in the art that the first seal 71, the second seal 72, the additional seal 73 and the inner channel seal 91 may have other shapes. As an example, the seal in the present application is made of a rubber material. Further, in the example of the present application, the first seal 71 is located above the second seal 72, but it will be understood by those skilled in the art that the first seal 71 may also be located below the second seal 72. Further, while the sealing mechanism of the present application includes two seals, one skilled in the art will appreciate that the present application may include any number of seals. Further, while the sealing mechanism of the present application includes two seals with free ends opposite one another, one skilled in the art will appreciate that the present application may include a greater number of seals with free ends staggered with respect to one another.

With continued reference to fig. 2 and 3, the window assembly of the present application further includes a drive arrangement for driving movement of the inner frame assembly 2 relative to the outer frame assembly 1. The driving device includes a driving body 921 and a supporting bar 922. The support lever 922 is connected to the driving body 921 and can be extended or retracted with respect to the driving body 921. The driving device is in communication connection with the control device. The control device is configured to control the start and stop of the drive device. As an example, the driving body 921 is provided on the inner sidewall 14 of the outer frame assembly 1, and the upper ends of the supporting bars 922 are connected with the inner frame body bottom 212 of the inner frame assembly 2. When the driving body 921 is extended, the inner frame member 2 is pushed up by the driving body 921 to be raised.

The window assembly of the present application has a first state and a second state. The top of the outer frame member 1 is disposed at approximately the same height as the top of the inner frame member 2 when the window assembly is in the first state. When the window assembly is in the second state, the top of the outer frame assembly 1 is lower than the top of the inner frame assembly 2. In other words, the distance between the top of the inner frame member 2 and the top of the outer frame member 1 when the window assembly is in the first state is less than the distance between the top of the inner frame member 2 and the top of the outer frame member 1 when the window assembly is in the second state. Therefore, when the window assembly is in the second state, a smoke passage is formed between the inner frame assembly 2 and the outer frame assembly 1, and the space in the basement can be communicated with the outer space on the ground. As an example, when a fire occurs in the basement, the window assembly is driven to the second state, whereby smoke can be quickly exhausted out of the basement.

It should be noted that although the inner frame member 2 in the present application is capable of moving relative to the outer frame member 1, in other embodiments, the inner frame member 2 may not move relative to the outer frame member 1.

Fourth, the window assembly of this application has the advantage of discharging smog fast. Specifically, the inner frame assembly of the present application is capable of movement relative to the outer frame assembly to form a smoke path between the inner frame assembly and the outer frame assembly to rapidly evacuate smoke from the basement.

The foregoing embodiments are merely illustrative of the principles and utilities of the present invention and are not intended to limit the utility model. Any person skilled in the art can modify or change the above-mentioned embodiments without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which can be made by those skilled in the art without departing from the spirit and technical spirit of the present invention be covered by the claims of the present invention.
