Description

Technical Field

[0001] The utility model belongs to the technical field of building doors and windows, and particularly relates to a detachable built-in aerogel blind. Background Art

[0002] In recent years, my country has made great progress in the construction industry, and the corresponding building energy consumption is still on the rise. With the country's emphasis on building energy conservation, low energy consumption and high comfort of buildings are the development trend of my country's construction industry. According to the 2019 GB / T51350-2019 "Technical Standard for Nearly Zero Energy Buildings", it is urgent to fully solve the problem of building energy consumption. In traditional buildings, the heat transfer through windows accounts for more than 20% of the total energy consumption of the building; in energy-saving buildings, after the thermal resistance of the wall is increased by the use of insulation materials, the heat loss of windows accounts for a greater proportion of the total energy consumption of the building.

[0003] The main reasons for heat loss in windows are: heat from solar radiation entering the building through the glass; heat loss through the glass, etc. Aerogel is a solid material with ultra-low density and porous structure, which has excellent thermal insulation and sound absorption properties. It is formed by solid materials (usually silica), and the gaps between its particles are very small, which can lock air molecules in them, thereby effectively preventing the conduction of heat and sound. Due to these characteristics, aerogel has been widely used in the fields of construction and environment.

[0004] Curtains are a common device for shading and heat insulation in houses. Unlike ordinary curtains, blinds are widely favored by homeowners for the light and shadow effects they create. Traditional blinds usually need to be installed and operated separately, and require a large space for installation. They are exposed to the air and are easily contaminated with dust and fumes after long-term use, making them difficult to clean. They are easily disturbed by external factors (such as wind) and make noises, which affects rest. Built-in blinds are directly embedded in the window frame, so that the blinds and windows form a whole, which has better stability and ease of use.

[0005] Existing built-in blinds generally include inner and outer glass-blinds-window frames, with blinds installed between the two layers of glass and fixed by window frames. The disadvantages of the existing technology are: 1) The existing blinds are mostly made of solid wood-aluminum alloy-PVC, etc. The above materials have high thermal conductivity and poor thermal insulation performance, and have little effect on the heat loss of the window. For example, the existing patent CN201620275267.6 is called a blind, and the blinds used are made of polyester fiberboard. This material has good sound absorption effect, but its thermal insulation performance is poor, and the heat loss of the window is still large, and the excellent thermal insulation and sound insulation performance of aerogel materials is not considered; 2) In terms of window structure, there are problems such as increased maintenance costs. For example, the existing patent CN201621236124.0 is called a hollow glass with built-in blinds, and its window frame is an integral structure. If the built-in blinds are damaged, the entire piece of glass needs to be replaced, which increases the maintenance cost of the built-in blinds and causes waste of resources; 3) If the built-in blind frame is detachable, the blinds have poor thermal insulation and sound insulation effects when not in use. Summary of the invention

[0006] In view of the problems existing in the background technology, the utility model provides a built-in blinds based on aerogel insulation and sound insulation, which improves the component structure of the traditional built-in blinds, adopts aerogel material as the main material of the blinds, and optimizes the thermal insulation performance of the curtains by adjusting the density and thickness of the aerogel, thereby achieving excellent thermal insulation and sound insulation performance. In addition, one side of the window frame is detachable, so that when there is a problem with the built-in blinds, it is easy to repair and replace. Finally, a three-layer glass and two-layer space structure is proposed, one layer is a hollow structure of built-in blinds, and the other layer is vacuum-treated, and a layer of glass is placed between the two layers to enhance the thermal insulation and sound insulation performance of the window.

[0007] In order to solve the above technical problems, the utility model adopts the following technical solutions:

The blind is parallel to the rotating shaft and is placed between the inner layer of glass and the middle layer of glass. The spring push switch is symmetrically installed on both sides of the single-sided detachable window frame to achieve the detachability of the built-in blind layer, which has no effect on the appearance of the window frame and does not affect its aesthetics. The space between the middle layer of glass and the outer layer of glass is vacuum treated to ensure the overall heat insulation and sound insulation performance of the window, reduce the heat loss of the window, and reduce the energy consumption of the building.

[0009] Preferably, an aerogel layer is arranged in the middle of the louver, and the two sides are symmetrically distributed, followed by a polylactic acid woven layer, a flame retardant-antibacterial finishing agent layer, and a decorative surface protective layer.

[0010] In a preferred embodiment, the spring push switch is welded to the base of the single-sided detachable layer, and the base of the detachable layer is fixed to form a closed vacuum space with the middle glass and the outer glass.

[0011] Preferably, the inner layer of glass, the middle layer of glass and the outer layer of glass form a two-layer space structure, the inner layer near the room is a built-in louver layer, and the outer layer is a vacuum layer.

[0012] Preferably, a plurality of shutters spaced apart from each other are arranged in the space between the inner layer of glass and the middle layer of glass, and the plurality of shutters are arranged in parallel. The window is provided with a mechanism for driving the shutters to adjust their angles and a lifting assembly for controlling the lifting of the shutters.

[0013] Preferably, the lifting assembly includes a pull rope arranged on the blinds and a rope reel arranged on a rotating rod on an axis parallel to the blinds.

[0014] Preferably, a through hole is provided on the blind, and the pull rope passes through the through hole.

[0015] Compared with the prior art, the advantages of the utility model are:

[0016] 1. The utility model combines ordinary blinds with glass windows to form built-in blinds, which effectively solves the problems of large installation space, easy to be contaminated with dust and oil smoke, difficult to clean, easy to be disturbed by external factors such as wind, and making noises that affect rest;

[0017] 2. The louver blades in the utility model include an aerogel layer, a polylactic acid woven layer, a flame retardant-antibacterial finishing agent layer, and a decorative protective layer. Aerogel is a solid material with ultra-low density and porous structure, and has excellent thermal insulation and sound absorption properties, effectively reducing heat loss from windows and reducing building energy consumption. The polylactic acid woven layer has a good antibacterial effect and is suitable for use in a residential environment. A layer of flame retardant finishing agent and antibacterial finishing agent is applied to the outside of the above layers to enhance their flame retardant-antibacterial effects. The outermost layer is a decorative protective layer to achieve aesthetic appearance;

[0018] 3. The utility model adopts a single-sided detachable window frame structure. The single-sided window frame is divided into two layers. The base is fixed to the middle glass and the outer glass to form a closed vacuum space, which enhances the heat insulation and sound insulation performance of the window. The base is symmetrically welded with a spring push switch, which connects the detachable frame base and the disassembly layer. The connection through the push switch has no effect on the appearance of the window frame and does not affect its aesthetics, thereby solving the problem of difficult maintenance of built-in blinds.
