Description
Technical Field
[0001] The present application relates to the field of glass manufacturing, and in particular to cold-resistant and energy-saving glass. Background Art
[0002] Hollow glass is widely used in the fields of construction, transportation, refrigeration, aerospace, etc. due to its excellent heat insulation, sound insulation, energy saving and other characteristics. It is usually glued to keep two pieces of glass at a certain distance, with dry air in the gap and then sealed with sealing materials around. It is mainly used in decoration projects with sound insulation and heat insulation requirements.
[0003] In the prior art, although hollow glass has certain thermal insulation properties, in the cold season in the north, since hollow glass does not have good cold resistance, long-term use in conditions of hot inside and cold outside can easily cause cracks in the glass, making it difficult to be widely used in the cold north. Utility Model Content
[0004] In order to improve the stability of glass when used in the cold environment of the north, the present application provides a cold-resistant and energy-saving glass.
[0005] The cold-resistant energy-saving glass provided in this application adopts the following technical solution:
[0006] A cold-resistant energy-saving glass comprises flat glass, low-emissivity glass and a sealing frame on which the flat glass and the low-emissivity glass are housed together, a hollow chamber is formed between opposite sides of the flat glass and the low-emissivity glass, the flat glass is located on the side facing outdoors, and a self-cleaning layer with a self-cleaning effect is provided on the side of the flat glass away from the low-emissivity glass, an energy collection layer is provided in the hollow chamber, the energy collection layer comprises two transparent films whose edges are heat-sealed to each other and located between the flat glass and the low-emissivity glass, and a plurality of solar energy collectors plastic-sealed between the two transparent films, a hot air component for blowing hot air toward the flat glass on the outdoor side is provided on the sealing frame, and the hot air component is electrically connected to the energy collection layer.
[0007] By adopting the above technical solution, the glass is used in cold northern regions. When the outdoors is covered with snow, the low-emissivity glass can block most of the ultraviolet radiation from entering the room. However, the excessively low temperature outside can easily cause ice to form on the outside of the glass, thus affecting the service life of the glass. At this time, a number of solar collectors fixed by transparent films in the glass absorb solar radiation toward the outdoors and convert the solar energy into electrical energy to supply power to the hot air component. Since the self-cleaning layer can make ordinary water droplets flow directly out of the glass sealing frame, the hot air component blows hot air to the flat glass, making it difficult for the surface to freeze, thereby keeping the glass surface clean and improving the stability when used in the cold northern environment.
[0008] Optionally, a mounting seat is provided on the side wall of the top frame of the sealing frame, the hot air component includes a micro heater arranged on the mounting seat and an air supply pipe connected to the air outlet of the heater, an ear plate is provided on the side wall of the top frame of the sealing frame, the air supply pipe is installed between the ear plate and the mounting seat, and the air supply pipe has a plurality of blowing ports opened along its length direction, and the plurality of blowing ports are all aligned with the outer surface of the flat glass.
[0009] By adopting the above technical solution, the solar collector converts the collected solar energy into electrical energy through wires and stores it in a battery, and then provides power to the heater through the wires. The heater delivers warm air to the air supply pipe and to the outer surface of the glass through a number of air outlets to reduce the possibility of icing on the surface, thereby improving the cleanliness of the glass surface and extending its service life.
[0010] Optionally, a cavity is opened at the top of the sealing frame, a battery is placed in the cavity, an input end of the battery is connected to an output end of the energy collection layer through a wire, and the heater is connected to the output end of the battery through a wire.
[0011] By adopting the above technical solution, the battery is used to store the electric energy converted from solar energy, and can continuously supply power to the hot air blower when there is no sunlight at night.
[0012] Optionally, an EVOH film for cold resistance is provided between the self-cleaning layer and the flat glass, and the outer surfaces of the flat glass and the low-emissivity glass are provided with PE films, wherein the PE film on the outer side of the flat glass is glued between the EVOH film and the self-cleaning layer.
[0013] By adopting the above technical solution, the EVOH film has good cold resistance and adapts to low temperatures, while the PA film has the advantages of puncture resistance and good gas barrier properties. By effectively combining materials with greater mechanical strength and materials with better low temperature resistance, a heat-resistant, low-temperature-resistant and highly transparent composite layer can be obtained, which improves the protective effect of flat glass and reduces the possibility of glass cracking due to large temperature differences or impacts.
[0014] Optionally, the self-cleaning layer is a TiO2 / SiO2 composite film containing nano-scale antibacterial agent particles.
[0015] By adopting the above technical solution, the surface of the TiO2 / SiO2 composite film is formed by the accumulation of secondary particles of TiO2, the particles on the surface of the composite film are finer, and the film is denser. The composite sol and film have better ultraviolet and visible light methylene blue degradation ability, and the final water contact angle can reach 0°, showing a more superior hydrophilic property, significantly improving the decomposition ability of oleic acid, and having stronger self-cleaning performance, thereby reducing the number of times the user cleans the side of the glass facing the outside, and reducing the difficulty of cleaning windows on high floors.
[0016] Optionally, a cleaning component for cleaning the surface of the low-emissivity glass is provided on the side of the sealing frame facing the interior of the room.
[0017] By adopting the above technical solution, due to the special material of low-radiation glass, conventional wiping cleaning methods can easily cause scratches on the surface of the low-radiation glass, thereby reducing the radiation protection effect of the low-radiation glass. Therefore, a suitable and convenient cleaning component is used to wipe and clean the surface.
[0018] Optionally, the sealing frame has two limit slide grooves vertically opened on the side wall facing the room, the two limit slide grooves are respectively located on both sides of the low-emissivity glass, and sliders are slidably arranged in the two limit slide grooves, and the cleaning assembly includes a brush rod connected between the two sliders and nylon brush filaments arranged on the side of the brush rod facing the low-emissivity glass, and the nylon brush filaments are in contact with the low-emissivity glass.
[0019] By adopting the above technical solution, the nylon brush wire has good softness, strong elasticity, acid and alkali resistance, high and low temperature resistance, and can easily remove dust on the surface of the low-radiation glass without causing scratches on the surface of the low-radiation glass. The user manually pushes the brush rod to slide back and forth along the length of the limiting slide groove, and the nylon brush wire can wipe the dirt on the low-radiation glass clean.
[0020] Optionally, a handle is provided on the brush rod, and the sealing frame is provided with a yield opening at the top end of each limiting slide groove corresponding to the slide block, and the yield opening is connected to the limiting slide groove.
[0021] By adopting the above technical solution, the setting of the clearance opening makes it convenient for the user to replace the brush rod by picking up the handle.
[0022] In summary, the present application includes at least one of the following beneficial technical effects:
[0023] 1. When using this glass in cold northern regions, when the outside is covered with snow, low-emissivity glass can block most ultraviolet radiation from entering the room. However, the low temperature outside can easily cause ice to form on the outside of the glass, thus affecting the service life of the glass. At this time, several solar collectors fixed by transparent films in the glass absorb solar radiation toward the outside and convert solar energy into electrical energy to supply power to the hot air component. Since the self-cleaning layer can make ordinary water droplets flow directly out of the glass sealing frame, the hot air component blows hot air to the flat glass, making it difficult for the surface to freeze, thereby keeping the glass surface clean and improving the stability of use in the cold northern environment;
[0024] 2. The solar collector converts the collected solar energy into electrical energy through the wire and stores it in the battery, which then provides power to the heater through the wire. The heater delivers the warm air to the air supply pipe and to the outer surface of the glass through several air outlets to reduce the possibility of ice on the surface, thereby improving the cleanliness of the glass surface and extending its service life;
[0025] 3. The battery is used to store the electricity converted from solar energy, and can also continuously supply power to the heat blower when there is no sunlight at night. BRIEF DESCRIPTION OF THE DRAWINGS
