Naturally ventilated synchronous opening/closing energy-saving window structure and its assorted sectional material

Abstract

The invention discloses an energy-saving window structure that can synchronously be opened and closed by natural aeration. The invention is the energy-saving window structure that can be opened from both sides and a sealed arbor wheel is arranged on the interlacing part of upper glass and lower glass. The sealed arbor with good sealing performance is parallel to a horizontal frame and fixed on a vertical frame. The diameter of the sealed arbor is the same with the diameter of a gap between the upper glass and the lower glass. Only four frames made of sectional material are required, so the invention has simple structure and the used sectional material is little. When the window is open, the upper and the lower parts of the window is open. So air with higher temperature rises and is exhausted from the upper part and the air with lower temperature descents and is exhausted from the lower part, and vice versa. So ventilation effect is good and natural. As the upper glass and the lower glass have same weight, the window ventilator of the structure provided by the invention reasonably and skillfully makes use of gravity balance principle. And the window is easy and energy-saving to be opened and closed. Only two moulds required by manufacturing the sectional material realizes the purposes of low manufacturing cost and cheap assorted sectional materials.

Description

technical field [0001] The invention relates to an industrial and civil building door and window structure and its profiles, in particular to a naturally ventilated synchronous opening and closing energy-saving window structure and its supporting profiles. Background technique [0002] The potential of envelope structure in building energy saving is already limited, mainly by improving the thermal insulation performance of doors and windows. Existing building doors and windows are single-glass left and right push-pull open building doors and windows, and the window sashes are also made of independent frame profiles, which not only have poor thermal insulation performance, but also use a large amount of frame profiles. The gap is large, and the sealing performance is very bad, resulting in serious waste of energy, which cannot meet the needs of energy saving. At the same time, there is no distinction between high and low levels, which is not conducive to air convection. [...

AI Technical Summary

Problems solved by technology

Existing building doors and windows are single-glass left and right push-pull open building doors and windows, and the window sashes are also made of independent frame profiles, which not only have poor thermal insulation performance, but also use a large amount of frame profiles. The gap is large, the sealing performance is very bad, resulting in serious waste of energy, which cannot meet the needs of energy saving

At the same time, there is no distinction between high and low levels, and it is not conducive to air convection.

[0003] In order to improve the thermal insulation performance of building doors and windows, although many window glass products have been developed, such as insulating glass, heat reflective film glass, low-e glass, vacuum glass, etc., the thermal insulation performance of window glass has been improved, but the existing The poor sealing performance of left and right push-pull open building doors and windows makes it difficult to reflect and exert the thermal insulation performance of medium and vacuum glass

Although the single-layer glass can be replaced by medium and vacuum glass by transforming the frame profile, due to the structure of the existing profile, the sealing between the frames is not good, so it is difficult to reflect and exert the thermal insulation performance of the medium and vacuum glass

[0004] Therefore, the existing building doors and windows have defects such as poor sealing performance, large amount of used profiles, and poor ventilation effect.
