Description

Technical Field

[0001] This utility model belongs to the field of doors and windows, and in particular relates to a door and window system with an integrated inward-opening screen. Background Technology

[0002] In architecture, a window is an opening in a wall or roof used to allow light or air to enter a room. While the original meanings of "window" and "door" refer to windows and doors respectively, in modern Chinese, "window" generally refers only to windows. Existing windows typically don't come with built-in screens. In summer, users usually install screens to keep insects out while maintaining ventilation. However, these aftermarket screens are unstable and can damage the existing window frame structure, affecting its strength. Furthermore, existing window frames and sashes are not flush, which affects aesthetics, easily accumulates dust, and makes cleaning and maintenance difficult. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides an integrated inward-opening window and screen system for doors and windows. This utility model has a strong overall structural rigidity and stability, comes with a built-in screen, saves space, and has better overall thermal insulation performance.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: an integrated window and screen system, comprising: a window frame, a sash frame, and a screen frame. The window frame includes an inner window frame profile and an outer window frame profile, which are connected by a thermal break strip. The sash frame includes an inner sash frame profile and an outer sash frame profile, which are flush with the inner window frame profile and connected by a thermal break strip. The screen frame is located on one side of the outer window frame profile and includes a screen frame profile and a screen sash profile. The screen frame profile is located between the outer window frame profile and the screen sash profile. The screen is fixed to the screen sash profile by a pressure strip, and the outer surfaces of the outer window frame profile and the screen frame profile are on the same horizontal plane.

[0005] Furthermore, both the outer and inner window frame profiles are provided with two heat insulation cavities, which are arranged sequentially along the thickness direction of the window frame. The outer heat insulation cavity of the outer window frame profile has a transverse pressing edge on its side facing the screen window.

[0006] Furthermore, the heat insulation strip is provided with at least two partition chambers, which are arranged along the length of the heat insulation strip.

[0007] Furthermore, the screen frame profile includes a rectangular cavity, with a screen sash pressing edge extending from the outer side of the rectangular cavity toward the screen window. The inner side of the rectangular cavity presses against the outer sash frame profile, and the lateral pressing edge presses against the outer side of the rectangular cavity. The lateral pressing edge and the screen sash pressing edge are located on the same horizontal plane.

[0008] Furthermore, the screen window sash profile includes a sash frame base, the sash frame base includes hollow cavities arranged side by side, the sash frame base extends out of the outdoor side with a groove for fixing the pressure strip, and the inner and outer sides of the sash frame base are provided with pressure grooves for installing sealing strips.

[0009] The advantages of this utility model compared with the prior art are as follows.

[0010] 1. In this utility model, the window frame and sash frame are on the same plane, with no significant height difference. This flush frame-sash design is not only visually simpler and more modern, but also easier to clean and maintain, avoiding the problem of dust accumulation and difficulty in cleaning the protruding part of the window sash in traditional non-flush designs. Furthermore, during opening and closing, the flush frame-sash window has a larger contact area between the window sash and the frame, resulting in better sealing. This is more airtight than thermally broken aluminum windows that require cutting rubber strips at the hinges, effectively preventing the penetration of air and moisture, and contributing to improved water tightness and sound insulation performance.

[0011] 2. This utility model features a specially designed embedded screen structure. This system integrates the screen into the window, saving space and facilitating daily use and cleaning. It does not affect the normal use of doors and windows while effectively preventing mosquitoes from entering.

[0012] 3. The multi-cavity design of this utility model not only helps with heat insulation and reduces condensation on the inside of the window, but also increases the overall rigidity and stability of the profile, thereby improving the overall energy efficiency of the building.

Detailed Implementation

[0018] like Figure 1 As shown, an integrated inward-opening window and screen system includes: a window frame 1, a sash frame 2, and a screen frame 3. The window frame 1 includes an inner window frame profile 11 and an outer window frame profile 12, which are connected by a thermal break strip 4. Both the outer window frame profile 12 and the inner window frame profile 11 are provided with two thermal break cavities 121, which are arranged sequentially along the thickness direction of the window frame 1. The outer thermal break cavity 121 of the outer window frame profile 12 has a transverse pressing edge 122 on its side facing the screen 33.

[0019] The window frame 1 has two independent heat insulation chambers 121, one inside and one outside. This four-chamber design not only helps with heat insulation and reduces condensation on the inside of the window, but also increases the overall rigidity and stability of the profile, thereby improving the overall energy efficiency of the building.

[0020] Furthermore, the thermal break strip 4 between the inner window frame profile 11 and the outer window frame profile 12 also adopts a multi-cavity design, with at least two partition chambers 41 set along the length of the thermal break strip 4. This multi-cavity design effectively increases the volume of the thermal insulation material, resulting in better mechanical properties. This further reduces heat conduction, increases the overall strength and stability of the doors and windows, improves their thermal insulation performance, and reduces heat transfer between the inside and outside of the partition chambers 41, providing a more comfortable living or working environment.

[0021] The sash frame 2 includes an inner sash frame profile 21 and an outer sash frame profile 22, with the inner sash frame profile 21 flush with the inner window frame profile 11. The window frame 1 and the window sash are on the same plane, with no significant height difference. This flush frame-sash design is not only visually simpler and more modern, but also facilitates cleaning and maintenance, avoiding the problem of dust accumulation and difficulty in cleaning the protruding part of the window sash in traditional non-flush designs. The inner sash frame profile 21 and the outer sash frame profile 22 are connected by a thermal break strip 4. Similarly, the thermal break strip 4 here also adopts a multi-cavity design to further reduce the heat conduction effect.

[0022] The screen frame 3 is located on one side of the outer window frame profile 12. The screen frame 3 includes a screen frame profile 31 and a screen sash profile 32. The screen frame profile 31 is located between the outer window frame profile 12 and the side sash frame 2 profile. The screen 33 is fixed to the screen sash profile 32 by a pressure strip 34. The outer surfaces of the outer window frame profile 12 and the screen frame profile 31 are on the same horizontal plane.

[0023] like Figure 2As shown, the screen frame profile 31 includes a rectangular cavity 311. A screen sash edge 312 extends from the outer side of the rectangular cavity 311 towards the screen window 33. The inner side of the rectangular cavity 311 presses against the outer frame profile 22, and a transverse edge 122 presses against the outer side of the rectangular cavity 311. The transverse edge 122 and the screen sash edge 312 are located on the same horizontal plane. Figure 3 As shown, the screen window sash profile 32 includes a sash frame base 321, the sash frame base 321 includes hollow cavities 322 arranged side by side, the sash frame base 321 extends out of the outdoor side to form a slot 323 for fixing the pressure strip 34, and the inner and outer sides of the sash frame base 321 are provided with pressure grooves 324 for installing sealing strips.

[0024] This utility model integrates the screen window 33 onto the outside of the system window by designing the screen window frame profile 31 and screen window sash profile 32. This does not affect the normal use of the door and window while effectively preventing the intrusion of mosquitoes and other insects. The screen window 33 can be equipped with a stainless steel mesh with a built-in safety lock, allowing for easy opening and closing as needed. Thieves cannot easily pry open the window to enter the room, thus enhancing security.
