Description
Technical Field
[0001] The utility model relates to the technical field of casement windows, in particular to a sealed casement window. Background Art
[0002] Casement windows are a common window style in residential houses. The window sash opens and closes along a certain horizontal direction, hence the name "casement window". Casement windows include a window frame profile group and a window sash profile group, which are combined with a screen fan to achieve ventilation while preventing mosquitoes from entering. They are particularly suitable for home use. The sealing effect of casement windows has always been a technical problem that the industry wants to solve. In the past, casement windows were divided into two parts, indoor and outdoor, and a broken bridge structure was set in the middle to separate them, thereby reducing heat transfer and sound transmission. Referring to the attached drawings, due to the current casement window abutment structure, a cavity is formed at the connection between the window sash profile and the glass after installation. In the closed state, the existing window sash and window frame are both sealed indoors by installing two staggered sealing strips on the indoor and outdoor sides. However, a cavity is also formed between the window sash and the window frame. The range of the two cavities covers the indoor and outdoor profiles, thereby forming a common cavity connecting the indoor profiles and the outdoor profiles, resulting in insufficient heat insulation and sound insulation performance of the casement window.

DETAILED DESCRIPTION
[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0017] As shown in the accompanying drawings, the utility model is a sealed casement window, comprising a window frame 1 and a window sash 2, wherein the window frame 1 comprises an outdoor frame profile 11, an indoor frame profile 12 and a first thermal break glue 13, and the window sash 2 comprises a glass 21, an outdoor sash profile 22, an indoor sash profile 23 and a second thermal break glue 24, which belongs to the existing thermal break casement window structure, and the reference Figure 5 On this basis, the window sash 2 profile and the glass 21 will form a common cavity 99, and a common cavity 99 will be formed between the window sash 2 and the window frame 1 in the closed state, and the first fixing block 14 and the second fixing block 15 are arranged on the inner side of the indoor frame profile 12 and the first thermal break glue 13, and the first abutting block 25 abutting against the first fixing block 14 is arranged on the outer side of the indoor sash profile 23, and the second abutting block 26 abutting against the second fixing block 15 is arranged on the outer side of the second thermal break glue 24, and the second fixing block 15 is arranged on the corresponding position of the original first thermal break glue 13, and the second abutting block 26 is arranged on the corresponding position of the original second thermal break glue 24, wherein the first fixing block 14 and the first abutting block 25, the second fixing block 15 and the second abutting block 26 are matched with one soft and one hard plastic, and the same The two parts are cross-matched. Specifically, if the first fixing block 14 is made of soft plastic, the first abutting block 25 is made of hard plastic, the second fixing block 15 is made of hard plastic, and the second abutting block 26 is made of soft plastic. In the form of soft and hard overlap, the soft plastic part abuts against the hard plastic part in the closed state, which will produce a certain deformation and fit the hard plastic part tightly, making the combination more sealed, thereby dividing the common cavity 99 between the window sash 2 and the window frame 1 into three cavities. The outdoor sash profile 22 and the indoor sash profile 23 are both squeezed and fixed to the glass 21 by a sealing strip. Two pressing blocks 211 are provided at the end of the glass 21. The two pressing blocks 211 are respectively arranged at the connection between the outdoor sash profile 22 / indoor sash profile 23 and the second thermal break glue 24. For example, Figure 1-3 The double inward-opening casement window with integrated screen fan 30 is shown. A sealing strip is provided between the screen fan 30 and the window sash 2. The screen fan 30 is also provided with a sealing strip abutting against the window frame 1. This structure is also applicable to casement windows without screen fan 30 or casement windows with one inward opening and one outward opening, such as Figure 4 As shown, a casement window with one opening inward and the other opening outward can also be used. The first fixing block 14 and the first abutment block 25 are changed from the indoor frame profile 12 and the indoor fan profile 23 to the outdoor frame profile 11 and the indoor profile of the veil fan 30. In addition, the indoor surface of the outdoor frame profile 11 is provided with a sealing strip for abutting the outdoor fan profile 22, and the outdoor profile of the veil fan 30 is also provided with a sealing strip for abutting the outdoor frame profile 11. It can also be applied to a casement window without a veil fan 30.
[0018] The utility model discloses a sealed casement window. A first fixing block 14 and a second fixing block 15 are arranged on a window frame 1, and a first abutting block 25 and a second abutting block 26 are arranged on a window sash 2. When the window sash 2 is in a closed state, the first abutting block 25 abuts against the first fixing block 14, and the second abutting block 26 abuts against the second fixing block 15, thereby forming two sealed cavities separating the window sash 2 and the window frame 1. Two pressure blocks 211 are arranged to separate the cavities of the glass 21 and the window sash 2, thereby disconnecting the mutual influence of the common cavity 99 of the indoor and outdoor profiles, thereby improving the heat insulation and sound insulation performance of the casement window.
[0019] In this embodiment, a first mounting portion 100 for mounting a first fixing block 14 is provided on the inner side of the indoor frame profile 12, and a second mounting portion 200 for mounting a first abutting block 25 is provided on the outer side of the indoor fan profile 23. The first mounting portion 100 and the second mounting portion 200 are both in the shape of a groove, with baffles protruding on both sides for connecting the first abutting block 25 and other components. A pressure cover 141 is provided on the first mounting portion 100, and the first fixing block 14 is installed through the pressure cover 141. The pressure cover 141 facilitates the installation of the first fixing block 14 and can increase the setting height of the first fixing block 14 so that it can abut against the first abutting block 25. The pressure cover 141 is buckled on the first mounting portion 100, and the first fixing block 14, the second fixing block 15, the first abutting block 25 and the second abutting block 26 are all installed by extrusion.
[0020] In this embodiment, the two pressing blocks 211 are fixedly connected to the indoor fan profile 23, the second thermal break glue 24 and the outdoor fan profile 22 by glue. The fixed connection by glue can further improve its sealing performance, and the pressing block 211 is arranged at the connection between the indoor fan profile 23 / outdoor fan profile 22 and the second thermal break glue 24 to tighten the gap with the help of the glass 21.
[0021] In this embodiment, partitions are provided inside the indoor frame profile 12 and the indoor fan profile 23, and the two partitions correspond to the first mounting part 100 and the second mounting part 200 respectively. The partitions are mainly used to increase the supporting force, and at the same time, the interior of the indoor frame profile 12 and the indoor fan profile 23 is changed from a single cavity to two or more cavities, which can improve the heat insulation and sound insulation performance.
