Description

Glass door and window with transparent sun-proof heat-insulation energy-saving rolling curtain

Technical Field

The invention belongs to the technical field of building energy conservation.

Background

The use of large glass windows has become a fashion building today. According to the research of relevant aspects, 70 percent of building energy saving is in doors and windows, and 70 percent to 90 percent of door and window energy saving is in glass. As is known to those who have learned physics, there are three ways and ways in which heat can be transferred: convection, conduction and radiation. Although the glass door and window with the cavity body structure, which has good sealing performance and is provided with the heat-resistant medium layer (such as the bridge-cut-off aluminum) and is formed by double-layer or triple-layer glass, can effectively block the convection and conduction of heat, the heat is difficult to block the radiation transmission of the heat through the transparent glass in a heat radiation mode. Therefore, the large glass door and window building without special radiation protection measures becomes a 'black hole' which wastes energy. In summer, due to the fact that sunlight and outdoor objects (outdoor buildings, trees and the like) which are heated by the sun, even outdoor hot air can radiate a large amount of heat into a room through window glass in a heat radiation mode, and the indoor temperature is rapidly increased. Although the cloth curtain can prevent the sun, the cloth curtain can not prevent the heat from flowing in, an air conditioner has to be used for cooling for a long time, and a large amount of electric energy is consumed for the cooling; in winter, the indoor temperature is higher than the outdoor temperature due to heating or heating by an air conditioner, and the indoor heat is greatly dissipated due to the heat radiation of the window glass, so that the heating load in winter is obviously increased, and the energy consumption is also increased. Some buildings adopt coated glass doors and windows with complex processes and high price, can reduce the heat radiation passing through curtain walls and window glass to a certain extent, and have better energy-saving effect. However, if the common coated glass capable of effectively blocking heat radiation is adopted, people often feel more cloudy and the sunshine is difficult to experience. In addition, in order to achieve better lighting and maintain indoor brightness, the used coated glass has higher transmittance to sunlight, so that the heat radiation blocking effect is not very strong, and the requirements of sun protection, heat insulation and energy conservation can not be well met. Moreover, the light transmittance and the reflectivity of the coated glass are fixed and cannot be adjusted according to the requirements (such as the requirements of different conditions of morning, noon, evening, sunny days, overcast and the like) after installation. A class of technical products for applying reflective window films in glazings has emerged and rapidly developed in recent years. The method of sticking the reflecting film in the glass window is utilized to reduce the radiation transmission of heat, reduce the consumption of electric energy of the air conditioner in summer and reduce the energy consumption of heating in winter. This is in fact an inexpensive alternative to coated glass. The problem is that this solution also lacks flexibility like coated glass. Once the reflecting film is attached, the light transmittance and the light reflection rate cannot be changed, and the ratio of the penetration and the reflection of sunlight cannot be changed along with the change of spring, summer, autumn and winter, the change of morning, noon and evening hours, and the change of cloudy days: it is not expected to penetrate much when it is needed (e.g., winter, morning and evening, cloudy day), and it is not expected to reflect much when it is needed (e.g., summer, noon, especially long-term east or west sun exposure of east or west window in the morning or afternoon). Meanwhile, the ratio of reflection and transmission of the reflection film to sunlight is also fixed by 'a hammertoe': if a film with more reflection and less transmission is selected to be mounted, the indoor space is dark and not bright; if a film with less reflection and more transmission is chosen, the room is much brighter, but the effect of blocking sunlight and saving energy consumption of air conditioner (and heating) is much less.

The Low-emissivity coated glass (namely Low-E glass) which appears and popularized in recent years has higher transmittance to visible light with the wavelength range of 380-780 nm, and is beneficial to indoor lighting; has high reflectance ratio to solar near infrared radiation and middle and far infrared radiation. Therefore, the low-emissivity glass can reduce the heat radiation transmission of indoor and outdoor heat through the glass on the premise of ensuring higher visible light transmittance, and has excellent heat insulation and heat preservation performance. However, because the manufacturing process of the glass is complex, the production condition is harsh, the multilayer composite film needs to be plated by consuming precious metal silver, the sealing treatment needs to be carried out in time after the silver plating, otherwise, the plated silver film is deteriorated in air, so the Low-E glass with real price is naturally expensive (especially the three-silver Low-E glass with excellent heat resistance and needing to be plated with 13 layers of films) and inconvenient to use in occasions where the sealing treatment cannot be carried out in time, especially for a large number of existing pure glass (white glass) door and window buildings, the original door and window needs to be replaced by using the Low-E glass to solve the heat radiation problem of the transparent glass, and the cost and the engineering quantity are not small.

Common energy-saving doors and windows in the market at present mainly have three main types: thermal insulating aluminum alloy glass doors and windows (commonly known as "bridge cut-off aluminum doors and windows"), plastic windows (commonly known as "plastic steel windows"), and aluminum-wood composite windows (commonly known as "aluminum-clad wood or wood-clad aluminum windows"). These windows and doors are generally designed to block heat from inside and outside by means of "convection" and "conduction", and generally do not solve the problem of "heat radiation" transmission of heat through the window and door glass except for the case of using coated glass.

In the existing energy-saving technology of building doors and windows, except for adopting the technology, the problem of sun-shading and sun-proof energy conservation is solved by adding an outer sun-shading shutter curtain which can resist wind and shade outside a large glass window; there are also blind roller blinds which can be electrically controlled and are installed in the cavity sandwich large glass door and window, and are called as "inner sun-shading roller blinds", except that the blind roller blinds are installed in the cavity sandwich large glass door and window and are made of conventional metal, plastic or composite materials.

The invention discloses a transparent heat-insulating energy-saving curtain (ZL200920277715.6), which is a patent item examined and confirmed by a patent right evaluation report of a patent office, wherein a reflective film layer is not coated on window glass (such as coated glass) or pasted on the window glass (such as window film), but is used as a curtain, and the curtain can be folded and placed as required, so that the problems of the coated glass and the pasted window film can be well solved: the transparent heat-insulation energy-saving curtain can not only select the transmission and reflection proportion of the used curtain body (curtain surface) material to visible light, infrared rays and ultraviolet rays as required, but also can reflect more (put down the curtain) when more sunlight is required to be reflected and transmit more (put up the curtain) when more sunlight is required to be transmitted by controlling the lifting of the curtain, has flexible operation and variable effect, and can be adjusted, controlled and converted easily as required, so that the requirements of sun protection, heat insulation, heat preservation and energy saving can be met, and the requirement of lighting can be met.

The inventor also proposed a transparent heat-insulating sun-screening energy-saving rolling curtain (ZL 201821210388.8) which is simplified and improved from the use point of view. A laminated glass door and window with a transparent sun-proof heat-insulating energy-saving roller shutter (ZL 201811619882.4) is proposed later, and is a technical scheme for combining a transparent heat-insulating energy-saving curtain with a high-grade three-layer glass (double-cavity) glass door and window, wherein the transparent heat-insulating energy-saving curtain is arranged in a second cavity close to the inside of the double-cavity glass door and window, so that the double-cavity glass door and window not only has high capability of blocking convection and conduction of heat inside and outside a room, but also can controllably block heat radiation of the heat passing through the glass, plays a role in transparent sun-proof heat insulation and energy saving, and can play a role in energy saving similar to that of the three-layer glass (double-cavity) glass door and window with Low-E glass at Low cost, and the capability of blocking the heat radiation can even exceed that of single-silver Low. Although the visible light transmittance is Low, the inside curtain can be folded, so that the visible light transmission capability of the white glass is better than that of the Low-E glass after the inside curtain is folded when high visible light transmission is required. Especially, the heat radiation prevention energy-saving technical improvement can be carried out on the existing white glass door and window without replacing the original white glass single-cavity (double-layer glass) or double-cavity (triple-layer glass) door and window.

At present, the glass door and window with the transparent sun-proof heat-insulating energy-saving rolling curtain provided by the inventor removes the interlayer in the name of the project, and is a technical scheme for combining the transparent heat-insulating energy-saving rolling curtain with a glass door and window with double-layer glass (single cavity) or triple-layer glass (double cavity), which is realized by lower cost and simplified structure and is more convenient for the energy-saving technical transformation of heat radiation prevention of white glass door and window products.

Disclosure of Invention

The invention provides a glass door and window with a transparent sun-proof heat-insulating energy-saving roller shutter, which is a technical scheme that a thin film type roller shutter or a blind type roller shutter in the technical scheme of the transparent heat-insulating energy-saving roller shutter is combined with a large laminated glass door and window with two layers of glass (single cavity) or three layers of glass (double cavity) and good heat-insulating performance by mounting the transparent sun-proof heat-insulating energy-saving roller shutter at the top of the indoor side of a glass frame of the glass door and window and adding a guide rail at the indoor side of a vertical frame, so that the glass door and window can not only have the excellent function of blocking heat from being transmitted inside and outside through convection and conduction paths, but also effectively block heat from being transmitted through the heat radiation of the door and window glass, and is a new product of the invention integrating the advantages of the two.

The invention relates to a glass door and window with a transparent sun-proof heat-insulating energy-saving rolling curtain, which adopts the mechanical structure and the control structure of the 'inner sun-shading rolling curtain' arranged in the prior sandwich glass door and window, but changes the conventional curtain body material into a plastic film rolling curtain or a shutter type rolling curtain with a metal mirror surface reflective film.

Different from the technical scheme of the patent of the transparent heat-insulating energy-saving curtain, the technical scheme is that the glass door and window with the transparent sun-proof heat-insulating energy-saving rolling curtain is not a pure curtain product, but is a product combining a laminated glass door and window (such as a bridge cut-off aluminum door and window) capable of effectively blocking heat transmission through convection and conduction with a transparent heat-insulating energy-saving curtain capable of effectively blocking heat transmission through glass radiation, wherein the used curtain body (curtain surface) with the transparent heat-insulating sun-proof energy-saving effect is not a freely-hung independent product but is a part of a combined product organically combining accessories and the laminated glass door and window. A transparent heat-insulating sun-screening energy-saving curtain serving as a fitting is arranged at the top of the indoor side of a large laminated glass door and window glass frame, and two ends which can contain the flat lower rod of the roller shutter are additionally arranged at the indoor side of the vertical frame from top to bottom so as to lead the shutter surface of the roller shutter to be close to the inner surface of the door and window glass to move up and down, the rolling shaft, the bracket and the control adjusting mechanism (a tubular motor or a manual zipper and the like) which can adjust the lifting of the curtain body are arranged at the top of the indoor surface of the laminated glass door and window frame, the curtain body (curtain surface) is made of a transparent plastic film which is plated with a single-layer or multi-layer composite metal material such as aluminum, copper, nickel, silver, chromium or tin, or an alloy or a compound thereof, or a dielectric reflective film, has a thickness of between a few angstroms and a few microns and can still keep a transparent effect to a certain extent; or the curtain body is a transparent or semitransparent plastic shutter plate of the shutter type curtain, the reflecting film is plated on the outer side of the transparent or semitransparent plastic shutter plate, or a layer of transparent plastic film plated with the reflecting film is attached to the outer side of the transparent or semitransparent plastic shutter plate; or the curtain body is formed by plating the reflective film on the outer side of the opaque plastic or metal shutter plate or attaching a layer of plastic film with the reflective film.

The indoor surface of the vertical frame of the glass door and window with the transparent sun-proof heat-insulating energy-saving rolling curtain is additionally provided with a guide rail, two ends of a metal or plastic flat lower rod which plays a role of flattening and weighting the curtain body of the window can be accommodated in the guide rail, the two ends of the lower rod can slide up and down in the guide rail, and the curtain body of the window curtain can be attached to the inner surface close to the glass of the glass door and window to move up and down through electric control or manual control, so that the window and window glass has the functions of effectively blocking heat from being transmitted indoors and outdoors through convection and conduction, and the transparent heat-insulating energy-saving curtain can effectively block heat from being transmitted indoors and outdoors through the heat radiation of the window and door glass, has the functions and flexibility of transparency, heat insulation, sun protection and energy saving, and has certain degree of sealing around the transparent sun-proof heat-insulating energy-saving used in the glass door and window with the transparent sun-proof heat-insulating energy-saving rolling curtain, compared with a freely suspended transparent heat-insulating energy-saving curtain, the curtain has better heat-insulating energy-saving effect, and the transparent heat-insulating energy-saving curtain is integrated with a glass door window of a modern building, so that the curtain is more matched. Even if the building design glass window has a certain front and back inclination angle, the curtain body as an accessory can be attached to the inner side close to the door and window glass and can move up and down along the guide rail without being separated from the door and window like the freely suspended curtain body.

It should be noted here that a freely hanging "transparent thermal insulation energy-saving curtain" usually has a large gap between the glass and the curtain surface (curtain body). When the sun shines, most of the sunlight reflected by the high-reflectivity curtain surface is reflected in the form of heat radiation, penetrates through the transparent glass and is emitted out of a room, and at the same time, a small part of the sunlight is reflected back by the glass and is reflected by the curtain surface again. In the process of repeated and gradually attenuated back and forth reflection, the gap between the glass and the curtain surface becomes a narrow space with higher temperature. In addition, larger gaps are formed at the periphery of the curtain body of the freely suspended transparent heat-insulation energy-saving curtain, so that hotter air in a narrow space between the glass and the curtain body can gradually flow into a room, and the heat-insulation and energy-saving effects of the transparent heat-insulation energy-saving curtain are reduced. Therefore, although the surface of the glass door and window with the transparent sun-proof heat-insulating energy-saving rolling curtain is only provided with the guide rail additionally, the glass door and window can move up and down along the guide rail, and actually, the glass door and window has a strict structure and a certain degree of tightness around, so that the glass door and window has better heat-insulating energy-saving effects than a freely-suspended transparent heat-insulating energy-saving rolling curtain product.

The technical scheme of the laminated glass door and window with the transparent sun-proof heat-insulation energy-saving roller shutter is different from the technical scheme of the laminated glass door and window with the transparent sun-proof heat-insulation energy-saving roller shutter without a laminated layer, the transparent heat-insulation energy-saving roller shutter is not arranged in the second cavity of the double-cavity glass door and window, but the arranged transparent heat-insulation energy-saving roller shutter can be closely attached to the vicinity of the inner surface of glass to move up and down under the constraint of a guide rail on the indoor surface of a single-cavity (double-layer glass) or double-cavity (triple-layer glass) door and window frame in the prior art by additionally arranging the guide rail on the indoor surfaces of the vertical frames at the two sides of the glass door and window, so that the heat radiation problem of large glass of the glass door and window is further solved on the basis of the original glass door and window product which has good sealing performance and can effectively block heat from being, the sun-proof, heat-insulating and energy-saving effects are obviously improved while the proper transparent effect is kept. The technical scheme of the prior laminated glass door and window with the transparent sun-proof heat-insulating energy-saving roller shutter is not only inconvenient to use in doors and windows with single cavity (double-layer glass) which are used in large quantity, but also the thickness of the second cavity is larger due to the fact that the transparent heat-insulating energy-saving roller shutter is arranged in the second cavity; the scheme of the glass door and window with the transparent sun-proof heat-insulating energy-saving roller shutter can be implemented when a new product is manufactured, and can realize the technical improvement of combining with the transparent heat-insulating energy-saving curtain by simply adding the guide rail on the frame for a large number of single-cavity (double-layer glass) or double-cavity (triple-layer glass) white glass door and window which are used currently, greatly enhance the capability of blocking heat from transmitting inside and outside through the heat radiation of the glass under the condition of keeping the adjustable required transparency, and is more suitable for being used on large glass door surfaces and show windows which are used currently, balconies of rooms or interlayer large glass windows of other places such as office buildings, offices, hospitals, schools, libraries, business halls, shops, villas and the like. For a large sandwich glass window formed by combining a plurality of small glass windows divided by a longitudinal and transverse grid type frame, a transparent heat-insulating energy-saving curtain can be installed on the upper part of the frame, and meanwhile, a guide rail which can penetrate through the vertical frame from top to bottom is additionally installed on the inner surface of the vertical frame, so that the curtain surface of the curtain can cross the transverse frame along the guide rail to move up and down. Therefore, the upper and lower laminated glass panes can be covered after the curtain surface is put down, and the transparent sun-proof heat-insulating energy-saving effect is achieved in the covering range.

As mentioned above, the glass door and window with transparent sun-proof heat-insulating energy-saving rolling curtain of the invention is a product combining a bridge-cut-off aluminum alloy glass door and window, a plastic window or an aluminum wood composite window which can effectively block heat from being transmitted inside and outside through a convection mode and a conduction mode with a transparent heat-insulating energy-saving rolling curtain which can effectively block heat from being transmitted in a heat radiation mode through glass of a curtain wall and the door and window, therefore, the overall structure of the invention comprises two parts: one part is a bridge-cut-off aluminum alloy door window or a plastic window or an aluminum-wood composite door window which is used as a substrate. The base body part belongs to the prior art, and can be a newly processed product or a product which is used in the prior art and is subjected to technical transformation; the other part is a transparent heat-insulating energy-saving curtain which is attached to the inside (indoor surface) of a base glass door and window and can move up and down along a guide rail. The two parts are organically combined together to form the glass door and window with the transparent sun-proof heat-insulating energy-saving rolling curtain.

The specific structure of the transparent heat-insulating energy-saving curtain used in the glass door and window with the transparent sun-proof heat-insulating energy-saving rolling curtain is as follows: the top of the glass door and window frame is provided with a bracket and a scroll of a transparent heat-insulating energy-saving curtain, a curtain body and a lower rod which are rolled on the scroll, and an electric or manual driving control and adjusting mechanism, and can also be movably and hermetically installed in the form of a curtain box (namely, the curtain box can be opened for maintenance or replacement when needed), and the indoor surfaces of the longitudinal frames at the two sides of the glass door and window are additionally provided with guide rails. The guide rail can accommodate two ends of the flat lower rod of the roller shutter and can enable the two ends to slide up and down along the guide rail so as to enable the shutter body (shutter face) of the roller shutter to move up and down close to the inner surface of the door window glass. If the frame is a single large-area glass door window, the guide rails can be arranged on the vertical direction of the longitudinal frames at the two sides and the vertical direction of the glass surface, so that the curtain body can move up and down closer to the inner surface of the glass; for the large-area glass window divided into a plurality of connected large-area glass windows by the grid-shaped frame, the guide rails can be vertically and penetratingly arranged on the longitudinal frames at the two sides in the direction parallel to the glass surface, so that the curtain body can cross the transverse frames along the guide rails and can move up and down in the vicinity parallel to the inner surface of the glass; although the curtain surface cannot be closely attached to the inner surface of the glass, the narrow space between the inner surface of the glass and the curtain surface is also closed by the guide rail. Such a structure is advantageous for improving the heat insulation and energy saving effects.

The curtain body of the invention is made by taking a transparent plastic film as a substrate, and plating a mirror surface reflecting film layer (a metal reflecting film for short) which has the thickness of between a few angstroms and a few microns and can still keep the transparent effect to a certain extent on the surface of the transparent plastic film layer by a vacuum coating or magnetron sputtering coating process, wherein the surface of the transparent plastic film layer is plated with metals such as aluminum, copper, nickel, silver, chromium, tin and the like, or alloys or compounds thereof, or a dielectric reflecting film and the like; or the curtain body is a transparent or semitransparent plastic shutter plate of the shutter type curtain, the metal reflective film is plated on the outer side of the transparent or semitransparent plastic shutter plate, or a layer of transparent plastic film plated with the metal reflective film is attached on the outer side of the transparent or semitransparent plastic shutter plate; or the curtain body is formed by plating the metal reflective film or attaching a layer of plastic film with the metal reflective film on the outer side of the opaque plastic or metal louver board.

The sun-proof heat-insulating energy-saving rolling curtain used in the glass door and window with transparent sun-proof heat-insulating energy-saving rolling curtain is used as a film type curtain or a plastic film material which is attached to a shutter curtain plate and is plated with a metal reflective film, usually polyester, nylon and other materials are used as a substrate, and the sun-proof heat-insulating energy-saving rolling curtain has a structure of a single film layer plated on the surface of the substrate and a multi-layer composite structure with a film coating layer, namely, a single-layer transparent plastic film plated with a metal reflective film which is stable in air and is plated with aluminum and the like can be directly used as a curtain body, or a composite structure film which is plated with the reflective film of aluminum, other metals or alloys or compounds thereof and is also compounded with a coloring layer, a glue coating layer, a. Of course, a multilayer composite film plating process such as Low-E glass plating may be used to plate a composite film having high transmittance for visible light and high reflectance for heat-radiating infrared rays on a plastic film. However, such products are not only costly, but also of little interest for retractable curtains.

The transparent plastic film is used for making a curtain body with a metal reflective film layer, and the thickness of the plated metal reflective film needs to be strictly controlled. The transmittance of the transparent conductive film against visible light may be selected from 1% to 60% and the blocking rate against infrared light may be selected from 50% to 100%, as required. The reflectance against ultraviolet rays is generally not low, and a predetermined range is not generally required. The metal reflective film plated or pasted on the opaque shutter curtain plate does not need the transmission capacity.

The invention relates to a glass door and window with a transparent sun-proof heat-insulation energy-saving rolling curtain, which has a specific mechanical structure similar to that of a conventional rolling curtain (an inner sun-shading rolling curtain), is integrated into a whole, is arranged at the top of a glass door and window frame, is provided with brackets at two ends, is provided with a cylindrical transverse shaft which is connected with the brackets at two ends and has a proper diameter, and is matched with a tubular motor or a manual control zipper mechanism; the upper end of the film or the louver of the curtain body is embedded in the slot of the transverse shaft, the curtain body is rolled on the transverse shaft, and the curtain body can be rolled up and down by controlling the forward and reverse rotation of the transverse shaft. The lower part of the curtain body is provided with a flat curtain lower rod which can drop and extend the curtain body (curtain surface) and move up and down along the guide rail and is made of plastic or metal with proper weight. The switch for controlling the forward and reverse movement of the motor is usually mounted on a nearby wall.

The glass door and window with the transparent sun-proof heat-insulation energy-saving roller shutter can obtain higher sun-proof heat-insulation effect than common coated glass at a relatively low cost without disassembling and replacing the original white glass door and window. The heat radiation blocking capability of the glass is stronger than that of single-silver Low-E glass and is equivalent to that of double-silver Low-E glass; the rolling curtain not only can show bright brightness of a pure glass window when being lifted, but also has unidirectional transparent capability to a certain extent even if the rolling curtain is completely put down, so that not only can people obviously feel the sun-proof and heat-insulating effect, but also people working indoors can see outdoor scenery clearly, and people are not confined in a dark room like a cloth curtain. For people using computers, the computer can also eliminate glare caused by sunlight to a great extent and protect eyes of people.
