Energy-saving and heat-insulating door and window structure

Abstract

This invention relates to an energy-saving and heat-insulating door and window structure, mainly consisting of a light-transmitting main plate mounted on an existing frame. The key feature is that a frame base is integrated into one side of the frame, and a light-transmitting secondary plate is located inside the frame base. A hollow chamber is formed between the secondary plate and the main plate. This secondary plate structure transforms a single-layer door / window into a double-layer door / window. Furthermore, the secondary plate contains heat-absorbing components such as tungsten oxide, antimony tin oxide, indium tin oxide, or tungsten oxide co-doped with alkali metals and halogens. Combined with the hollow chamber, this effectively blocks heat conduction, achieving excellent heat insulation and soundproofing, thereby reducing the energy output of air conditioning or heating equipment within the space. This not only achieves energy-saving effects but also enhances the overall strength and typhoon resistance of the door / window.

Claims

1. A door and window structure with energy-saving and heat-insulating properties, mainly comprising a light-transmitting main plate mounted on an existing frame, wherein the frame forms first and second frame edges on two sides opposite to the light-transmitting main plate, characterized in that: the first frame edge of the frame is coupled to a frame base, the frame base is provided with a set of grooves corresponding to the first frame edge, and a fitting groove is provided on the end face of the frame base corresponding to the light-transmitting main plate, wherein a light-transmitting secondary plate is mounted in the fitting groove, and a hollow chamber is formed between the light-transmitting secondary plate and the light-transmitting main plate.

2. The energy-saving and heat-insulating door and window structure as described in claim 1, wherein the light-transmitting sub-panel is made of PC or PET sheet.

3. The energy-saving and heat-insulating door and window structure as described in claim 1 or 2, wherein the light-transmitting sub-panel contains one of the following materials: tungsten oxide (CWO), antimony tin oxide (ATO), indium tin oxide (ITO), or tungsten oxide [M xWO 3-yA y] co-doped with alkali metals and halogens.

4. The energy-saving and heat-insulating door and window structure as described in claim 1 or 2, wherein the light-transmitting sub-panel is bonded to the fitting groove of the frame base by an adhesive method.

5. The energy-saving and heat-insulating door and window structure as described in claim 1 or 2, wherein the frame base is bonded to the first frame edge of the frame body by an adhesive method.

6. The energy-saving and heat-insulating door and window structure as described in claim 4, wherein the frame base is bonded to the first frame edge of the frame body by an adhesive method.

7. The energy-saving and heat-insulating door and window structure as described in claim 1 or 2, wherein a protective layer is provided on each of the two sides of the light-transmitting sub-panel.

8. The energy-saving and heat-insulating door and window structure as described in claim 1 or 2, wherein an anti-fog layer is coated on the side surface of the light-transmitting sub-panel corresponding to the light-transmitting main plate.

9. The energy-saving and heat-insulating door and window structure as described in claim 7, wherein an anti-fog layer is coated on the side surface of the light-transmitting sub-panel corresponding to the light-transmitting main plate.
