Description

Technical Field

[0001] The present application belongs to the technical field of doors and windows, and in particular to a sealing structure of an inward-opening window and an inward-opening window. Background Art

[0002] Inward-opening windows are a common type of window used in buildings, and their sealing performance is a key indicator of their performance. They typically provide basic properties such as sound insulation, heat insulation, and waterproofing. When an inward-opening window is closed, the sealing strips on the sash and frame are separated, leaving a gap between them. Consequently, existing inward-opening windows suffer from poor sealing performance, resulting in issues with airtightness, watertightness, and sound insulation.

[0003] In addition, in order to expand the window's field of view and lighting, the inward-opening window will be designed without a middle column. However, this traditional inward-opening window structure generally has the technical problem of poor sealing. The main reason is that the window sash loses the cooperation of the middle column, which makes it easy to have poor sealing problems.

[0004] In view of the technical problems existing in the prior art, a kind of inward opening window with good sealing performance is needed. Utility Model Content

[0005] The primary purpose of the present application is to solve at least one of the above problems and provide an inward-opening window sealing structure and an inward-opening window. To meet one of the purposes of the present application, an inward-opening window is provided, which adopts the following technical solution:

[0006] An inward-opening window sealing structure is provided to meet one of the purposes of the present application, including a window frame and a window sash hinged to the window frame, the window frame is provided with a first sealing strip, and the outer frame of the window sash is provided with a second sealing strip. It is characterized in that a plurality of seals are provided on the window sash frame, each of the seals has an inner surface and an outer surface, and the inner surface abuts the second sealing strip; when the window sash is closed to the window frame, the outer surface of each seal is in contact with the corresponding part of the first sealing strip.

[0007] Furthermore, the sealing member is provided at a corner of the window sash frame.

[0008] Furthermore, the plurality of seals are two seals, which are respectively arranged at two corners of the window sash frame close to the center of the window frame.

[0009] Furthermore, the plurality of seals are four seals, which are respectively arranged at the four corners of the window sash frame.

[0010] Furthermore, the cross section of the sealing member is stepped and the inner surface is covered with the second sealing strip.

[0011] Furthermore, rounded transition sections are provided between the steps on the outer surface of the seal.

[0012] Furthermore, the outer surface of the seal has a first area and a second area, and rounded transition sections are provided between the steps of the first area, and right-angle transition sections are provided between the steps of the second area.

[0013] Furthermore, a window sash piece is provided on the frame of the window sash, and the bottom end of the window sash piece is fixedly connected to the sealing member.

[0028] The present application provides an inward-opening window sealing structure, which enables the inward-opening window to have better sealing performance.

[0029] In a typical embodiment of the present application, Figures 1 to 3-2As shown, this embodiment shows an inward-opening window sealing structure, including a window frame 10 and a window sash 20. The window frame 10 is hinged to the window sash 20, and the window sash 20 can be opened and closed relative to the window frame 10 via the hinge. A first sealing strip 101 is provided on the window frame 10. The window frame 10 is made of an alloy material and has a hook. The first sealing strip 10 has a hook groove that matches the hook, so that the first sealing strip 101 can be firmly connected to the window frame 10. In addition, the first sealing strip 101 is of the same length as the window frame 10, which is equivalent to the first sealing strip 101 being arranged along the window frame 10, so that the first sealing strip 101 is provided on the entire window frame 10; similarly, a second sealing strip 201 is provided on the outer frame 202 of the window sash 20. The second sealing strip 201 is arranged around the outer frame 202, so that the second sealing strip 201 is arranged on the outer frame 202 of the window sash 20. Like the window frame 10, the outer frame 202 of the window sash 20 is also made of alloy material and is provided with a hook on the outer frame 202. The second sealing strip 20 also has a hook groove that matches the hook. The hook and the hook groove match so that the second sealing strip 201 can be firmly connected to the outer frame 202. A plurality of sealing members 30 are provided on the window sash frame. The specific structure of the sealing member 30 is as follows: Figure 2-1 to Figure 2-4 As shown, the seal 30 has an inner surface 304 and an outer surface 303. The seal 30 is positioned at the corner 102 of the window sash 20. The inner surface 304 abuts the second sealing strip 201. When the window sash is closed to the window frame, i.e., when the inward-opening window is closed, the outer surface 303 of each seal 30 abuts the corresponding portion of the first sealing strip 101. This sandwiches the seal 30 between the window sash 20 and the window frame 10, that is, between the first and second sealing strips 101, 201, filling the gap between them and providing the inward-opening window with improved sealing performance.

[0030] In various embodiments, Figure 1 and Figure 2-1 A single sealing member 30 may be provided at any one of the corners 102 of the window sash 20. Alternatively, two sealing members 30 may be provided, one at each of the two corners 102 of the window sash 20, with the two sealing members 30 being provided at two corners 102 of the outer frame 202 of the window sash 20 near the center of the window frame 10. In another embodiment, a sealing member 30 may be provided at each of the four corners 102 of the outer frame 202 of the window sash 20. This arrangement further enhances the sealing performance of the inward-opening window.

[0031] In another embodiment, Figure 2-2 to Figure 2-3As shown, the sealing member 30 has a stepped cross-section, and when the sealing member 30 is installed on the window sash 20, the inner surface 304 of the sealing member covers the second sealing strip 201. To further improve the sealing performance of the inward-opening window, a rounded transition section 305 is provided between the steps on the outer surface 303 of the sealing member 30. The shape of the rounded transition section 305 is more consistent with the shape of the first sealing strip 101, which can further improve the sealing degree after the two abut.

[0032] In another embodiment, Figure 2-3 and 2-4 As shown, the outer surface of the seal 30 is divided into a first region 301 and a second region 302. Rounded transition sections 304 are provided between the steps in the first region 301. The shape of these rounded transition sections 305 better matches the shape of the first sealing strip 101, further improving the sealing between the two after contact. Right-angled transition sections are provided between the steps in the second region 302. These right-angled transition sections match the right-angled shape of the window frame 10, making them more aligned and improving the sealing. In other words, the steps on the seal 30 are provided with both right-angled and rounded transition sections, which can be flexibly adjusted according to the actual application scenario. This is intended to better cooperate between the sealing strips on the window sash and the window frame, thereby improving the sealing performance of the inward-opening window.

[0033] In another embodiment, Figure 3-1 and 3-2 As shown, a window sash piece 205 is provided on the frame of the window sash, and the bottom end of the window sash piece 205 is fixedly connected to the sealing member 30. In a window without a center pillar, the cooperation between the window sash piece 205 and the sealing member 30 can serve as the center pillar of the window. Through the sealing cooperation between the sealing member 30 and the first sealing strip 101 of the window frame 10, even if the window does not have a center pillar, the window without a center pillar can still have better sealing performance.

[0034] In another embodiment of the present application, Figure 2-2 to Figure 2-4 As shown, the sealing member 30 is provided with a plurality of square slots 306 , which can cooperate with the second sealing strip 201 to provide better sealing performance.

[0035] The present application also provides an inward-opening window, which includes the inward-opening window sealing structure described in any one of the above technical solutions. Compared with the closest prior art, the present application provides multiple seals on the window sash frame, so that the outer surfaces of the multiple seals all face the first sealing strip on the window frame. When the window sash is closed on the window frame, the outer surface of each seal fits with the corresponding part of the first sealing strip and has a certain degree of extrusion, so that the seal can provide sealing performance at the corner of the inward-opening window, that is, the sealing strip on the window sash and the sealing strip on the window frame are abutted and fitted as a whole, and there is no residual space between them, so as to improve the sealing performance of the inward-opening window. The inward-opening window can maintain a stable indoor temperature, achieve energy-saving and environmental protection effects; and can further extend the service life of the inward-opening window.
