Description

Technical Field

[0001] This utility model relates to the field of door and window technology, and in particular to a double-thermal-break inward-opening window with an optimized thermal insulation structure. Background Technology

[0002] Currently, one of the most common types of windows in residential buildings is the casement window. The casement window sash moves in a horizontal direction when it opens and closes, hence the name "casement window". Casement windows are generally divided into inward-opening and outward-opening types, which are casement windows that open separately to the inside and outside.

[0003] For example, a double-thermal-break double-inward-opening casement window with patent application number 202421638671.6, which improves the low-frequency sound absorption capacity of doors and windows, has a frame, a screen sash, and a glass sash, with the frame forming the window frame of the double-thermal-break double-inward-opening casement window. Although both the frame and the glass sash adopt a four-cavity structure, the sashes are only overlapped with one waterproof strip, one sealing duckbill strip, and two sealing strips. In particular, at the connection between multiple cavities, there is only one sealing duckbill strip. This results in the actual thermal insulation performance being no different from that of a three-cavity structure, and the design is very unreasonable. Therefore, it is necessary to make further improvements. Utility Model Content

[0004] The purpose of this invention is to provide a double-thermal-break inward-opening window with an optimized thermal insulation structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a double-thermal-break inward-opening window with optimized thermal insulation structure, comprising a sash body and a frame body. The sash body includes an outer sash, a middle sash, and an inner sash connected sequentially by thermal insulation strips. A central sealing strip is fixed on the frame body. The central sealing strip is provided with a first sealing part, a second sealing part, and a third sealing part. When the sash body is closed, the first sealing part abuts against the outer sash, the second sealing part abuts against the middle sash, and the third sealing part abuts against the inner sash.

[0006] Furthermore, the outer fan, middle fan, and inner fan are arranged in a stepped manner. The first sealing part forms a first sealing point at the contact point with the outer fan, the second sealing part forms a second sealing point at the contact point with the middle fan, and the third sealing part forms a third sealing point at the contact point with the inner fan. The first sealing point, the second sealing point, and the third sealing point are arranged in a stepped manner.

[0007] Furthermore, the frame includes an outer frame, a middle frame, and an inner frame connected in sequence by heat insulation strips.

[0008] Furthermore, the outer frame and the middle frame, as well as the middle frame and the inner frame, are connected by two thermal insulation strips, and the space between the two thermal insulation strips is filled with thermal insulation material.

[0009] Furthermore, the side of the central sealing strip away from the fan body is provided with a first connecting part and a second connecting part. The first connecting part is snapped onto the heat insulation strip between the outer frame and the middle frame, and the second connecting part is snapped onto the heat insulation strip between the middle frame and the inner frame.

[0010] Furthermore, the inner fan has a baffle on the side facing the inner frame closer to the interior, and an internal sealing strip is provided on the inner side of the baffle. The internal sealing strip abuts against the inner frame, and the third sealing part abuts against the side of the inner fan closer to the exterior.

[0011] Furthermore, a first external sealing strip is provided on the outer frame, and the first external sealing strip abuts against the outer fan.

[0012] Furthermore, it also includes a gauze fan, which is openable and closable on the outer frame. The first external sealing strip abuts against the side of the gauze fan closest to the outside. The side of the gauze fan closest to the inside is provided with a second external sealing strip. Preferably, the second external sealing strip abuts against the outer fan. The side of the first panel closest to the second panel has a rounded transition.

[0013] Compared with the prior art, the beneficial effects of this utility model are: by fixing a central sealing strip on the frame, and by having the first sealing part, the second sealing part, and the third sealing part of the central sealing strip abut against the outer sash, the middle sash, and the inner sash respectively, multiple heat insulation cavities are formed between the central sealing strip and the sash body, thereby improving the airtightness and watertightness between the sash body and the frame, and thus improving the heat insulation performance of the doors and windows.
