[0002] In the field of modern architecture, windows are not only an important part of a building but also an important medium for indoor and outdoor environmental communication. The design and function of windows directly affect the energy efficiency of buildings, the comfort of the indoor environment, and the aesthetics of buildings. With the increasing requirements for building energy conservation and aesthetics, casement windows are widely used due to their good sealing performance and adjustability. This type of window allows users to ventilate as needed and provides good heat insulation and sound insulation when closed. However, the existing casement windows have the following problems:

[0003] In the design of existing casement windows, due to the accuracy limitations in the manufacturing and assembly processes, it is difficult to make the cross-sectional height of the opening frame of the opening sash group the same as that of the total frame used to fix the opening sash group. This difference results in redundant lines on the entire window form when the opening sash is in the closed state, damaging the aesthetics of the window, making the appearance of the window look less smooth and coordinated, affecting the visual unity of the fixed sash group and the opening sash group, and thus reducing the integrity of the building's appearance.

[0024] The hinge connection between the left end of the opening sash group 3 and the general frame 1 can be a hinge connection. The specific principle of the hinge connection is prior art and will not be elaborated here;

[0025] Preferably, the inner frame 11 and the outer frame 12 are hollow structures, the fixed frame 21 is a multi-cavity hollow structure to reduce weight and the transmission of sound and vibration energy, and the fixed window panes 22 and the opening window panes 32 are preferably double-pane glasses.

[0026] The hidden sash casement window of the present utility model shields the fixed frame 21, the opening frame 31 and the inner frame 11 through the outer frame 12, so that the outer side wall of the outer frame 12 forms an integrated planar structure, thereby achieving the effect of hidden sashes. In the closed state, there are no redundant lines on the whole window, and it is not easy to distinguish the fixed sash group 2 and the opening sash group 3 from the outdoor side, which has aesthetics and integrity.

[0027] It should be noted that since the connection structures between the four sides of the fixed fan group 2 and the general frame 1 are the same, and the connection structures between the upper, lower, and right ends of the opening fan group 3 and the general frame 1 are the same, in this embodiment, only the connection structures between the lower end of the fixed fan group 2 and the upper end of the opening fan group 3 and the general frame 1 are taken as examples for illustration.

[0028] To improve the heat insulation and heat preservation performance of the general frame 1, the inner frame 11 and the outer frame 12 are connected by a general frame heat insulation strip 13.

[0029] To improve the sealing performance and anti-vibration performance of the fixed window pane 22, sealing strips are provided between the fixed window pane 22 and the fixed frame 21 and the outer frame 12, and the side of the fixed window pane 22 is connected to the general frame 1 through a first gasket 22a.

[0030] Preferably, support strips 12a for supporting the first gasket 22a are provided on both the outer frame 12 and the general frame heat insulation strip 13. So that a plurality of cavities are formed between the first gasket 22a and the general frame 1 and the fixed frame 21, which is beneficial to consuming vibration energy.

[0031] As Figure 3 shown, the opening frame 31 includes an inner opening frame 311, a connecting frame 312, and an opening plate 313 arranged in sequence from the indoor side to the outdoor side.

[0032] To improve the heat insulation and heat preservation performance of the opening frame 31, the inner opening frame 311 and the connecting frame 312 are connected by an opening frame heat insulation strip 314.
