Description

  The present invention relates to a heat ray using a multi-layer glass which is a glass member, far-infrared invasion prevention glass, and breakage detection of a glass material.

  People want a more comfortable environment. Various glass members are used in houses and offices. The glass member promotes the health of people who live and work in a comfortable space and contributes to work efficiency.

  Furthermore, it is still efficient if external light can be controlled to maintain a comfortable space using a high-performance multilayer glass member. It would be convenient if it had a function to protect internal people from crime. For this purpose, a glass member having a strong structure with high safety is required.

  The ideal glass member is a glass member that absorbs long-wave heat rays in the sunlight, near infrared rays, reflects far infrared rays and blocks light of unnecessary wavelengths, and has strength in the event of a disaster, It is better if the structure can withstand storms and floods and cannot easily be entered by criminals.

  Various glass members have been proposed so far. The same applies to the multi-layer glass, and there are other glass plates enclosing metal wires and mesh plate glasses. It has the effect of tempered glass.

  It is due to radiation that the solar heat directly heats the ground without heating the air on the way. Radiation is a process that follows Maxwell's equations by energy transfer by electromagnetic waves. Infrared rays of invisible light are mainly useful for transferring heat and have a wavelength of 0.75 μm to several millimeters and are also called heat rays.

  The double-glazed glass is two laminated glasses, and is formed by combining a glass that absorbs near infrared rays (0.8 to 1.5 μm) and a glass member that reflects far infrared rays (1.5 μm or more). Therefore, it is possible to avoid a phenomenon in which the room gets hot.

  Double-glazed glass provides energy saving effects due to sound insulation, strength, and temperature cutoff. However, since water vapor accumulates inside and is easily clouded, or because of the structure, it is made of two glass materials, the thickness of the glass member becomes so thick that a conventional sash for housing the glass member cannot be used. Therefore, since the glass sash must be replaced, the cost burden increases. In addition, the mounting process was difficult.

Therefore, the present invention provides a configuration that takes advantage of the double-glazed glass and has the same thickness as that of a conventional glass member and does not require replacement or processing of a sash. Provided is a configuration of a glass member having an energy saving effect in which moisture is not accumulated inside the glass member and is always kept transparent, absorbing heat rays and near infrared rays, and reflecting far infrared rays and preventing heat from passing through the inside.
JP 2007-39299 A JP2007-2656 EDN JAPAN no. 74 2007.4 pp81-84

  One of the problems to be solved is to remove the water vapor and moisture accumulated inside the double-glazed glass so that it does not become cloudy. Since the double-glazed glass has a structure in which two sheets of glass are combined, it necessarily becomes thick. Therefore, when replacing with a conventional plate glass, there is a drawback in that the sash containing the glass body is also replaced.

  Even if the glass member shrinks due to a temperature difference between the outside and the room, the generation of water vapor inside the double-glazed glass is prevented without impairing the sound insulation effect, and the glass surface is not clouded. It realizes the energy saving effect of absorbing near infrared rays and reflecting far infrared rays.

  In the present invention, in order to solve the above problems, the glass on the outdoor surface is made of a glass material containing a heat ray absorbing material and a heat ray reflective glass material. Of the heat rays contained in solar energy, near infrared rays are absorbed without being transmitted inside. Far infrared rays are reflected and cannot enter the room.

  The two glass members are provided with a slight gap or gap by an extremely thin spacer containing a desiccant. This gap provides a gap that reflects at least a far-infrared wavelength of 1.5 μm or more and discharges it to the outside. A far-infrared reflective coating agent is applied to the outside of the indoor glass body, or a heat ray or far-infrared reflective film is pasted.

  Absorbs at least heat rays and near infrared rays from external light and reflects far infrared rays. Therefore, since the summer sun can be shielded, it is possible to protect the human body and property from the heat. Furthermore, energy saving effect can be expected.

  The multilayer glass according to the present invention is provided with a heat ray absorbing glass member on the outside air surface, and a slight gap for wavelength reflection of far infrared rays is provided in the inner glass member. This gap is formed of a material made of an adhesive that adheres the outside and the inside and a desiccant that also serves as a spacer for obtaining the gap. The thickness of this material is extremely thin, and only needs to be the far-infrared reflected wave propagation length. Therefore, 1 or 2 mm is sufficient. A conventional home glass sash can be used as it is. The conventional glass groove is about 9 mm. If it falls within this range, it can be exchanged for this double-glazed glass without any special processing.

  Water vapor and moisture generated inside the multi-layer glass member are absorbed by the desiccant material of the spacer, so that the glass is not fogged. In addition, the ultra-thin gap is provided, so that there is an effect of sound insulation, sound insulation and heat conduction. Furthermore, since the thickness is the same as that of the conventional plate glass, the replacement and processing of the sash for attaching the glass is simple.

  The external side of the multi-layer glass is composed of a glass member that reflects and reflects sunlight heat rays and near infrared rays. The inner glass member has an effect of absorbing near infrared rays and far infrared reflection coating on the outer surface to prevent the penetration of near infrared rays and far infrared rays into the room and protect the human body from the heat of the sun.

First embodiment

  The present invention relates to the configuration of glass members such as buildings, vehicles, ships, airplanes, and show windows. This will be described below with reference to FIGS.

  FIG. 1 shows an overall view of the multilayer glass of the present invention. In the figure, 11 indicates the overall structure of the double-glazed glass, and 12 and 13 are glass bodies. In the illustrated example, 13 is the outdoor side, and 12 is the indoor side.

  Reference numeral 14 denotes a gap between the glass bodies 12 and 13. This gap is very thin and necessary for reflection of heat rays and far infrared rays. Therefore, when replacing with a conventional glass member, the home glass sash does not need to be renewed, and there is no need for additional processing of the sash. Existing ones can be used as they are.

  Reference numeral 15 denotes an adhesive, which may be a double-sided tape. Reference numeral 16 denotes a spacer, and a member containing a desiccant is used in the present invention. Reference numeral 16a denotes an exposed portion of the spacer and the desiccant, which has an action of enhancing the drying effect because no adhesive is attached. It absorbs moisture, water vapor, and condensation accumulated in the gaps 14 and prevents the glass bodies 12 and 13 from fogging.

  The adhesives 15 and 16 cover the periphery of the multilayer glass and fix both glass members. FIG. 1 is a cross-sectional view, in which 15 and 16 are shown vertically. Further, one of the glass members 12 and 13 is longer than the other.

  As shown in the figure, a step is provided to make it asymmetric. This is because a sealing agent made of silicon rubber or the like indicated by 17 and 18 is easily placed and the glass members 12 and 13 are firmly fixed. If one of 12 or 13 is made of a tempered glass member, the crime prevention and disaster prevention effects can be synergized.

  In the conventional example, the sealing of 17 and 18 is provided with a spacer in the center and 16 is a T-shaped structure. 12 and 13 have the same size and are symmetrical. Therefore, a multi-layer glass can be constructed by providing a spacer below the center of the ceilings 17 and 18 and applying the adhesive 15 to the spacer 16 with the glass bodies 12 and 13 sandwiched therebetween to fix both glass members. As described above, the drying effect can be enhanced by the desiccant protrusion 16a.

  FIG. 2 shows a model for removing heat rays and far infrared rays when sunlight passes through the multilayer glass body of the present invention. In the figure, a part of sunlight 21 is reflected from 13 and discharged to the outside as indicated by 22. The glass material on the outer side 13 absorbs near infrared rays of 0.75 μm to 4.0 μm. Visible light is 0.4 μm to 0.75 μm. The material has a structure containing cobalt, iron dioxide, tin oxide and the like.

  The glass member 13 containing such a substance absorbs the wavelength of sunlight, also called near-infrared rays and heat rays, during the passage of 13. Far-infrared light passes through 13 and reaches 12. A far-infrared reflecting agent is coated on the gap surface on the inside of 12. Alternatively, a film-like transparent conductive film is pasted inside the glass member 12. Reference numeral 24 denotes far infrared rays reflected by the coating.

  The 12 glass members contain oxidized indium and the like to absorb and block far infrared rays. Far infrared rays are electromagnetic waves. An electromagnetic wave is a wave in which an electric field and a magnetic field are alternately pushed. Sunlight includes electromagnetic waves of all wavelengths ranging from γ (gamma) to radio waves. Among them, a wavelength region of 0.75 μm to 1,000 μm is far infrared rays.

Among them, the wavelength region of 4 μm to 1,000 μm is far infrared rays. Far infrared rays give kinetic energy to molecules with electrical polarity. Giving vibration energy to molecules to activate movement. The molecule is moving. It is said that the speed of hydrogen molecules is 1.8 km / sec, the distance that can run straight is 1.78 × 10 ⁻⁵ cm, and the number of collisions with other molecules is 10 billion times per second.

  Molecules that gain far-infrared energy accelerate and collide with other molecules. At that time, the collision becomes heat. Far infrared itself is not heat. It is an electromagnetic wave that causes the other molecule to self-heat. Far-infrared rays are easily absorbed by organic matter, and change to heat when absorbed. There are three types of heat transmission: heat conduction, convection, and radiation. Far infrared is only radiative transfer. There is a difference that heat warms the surface of a substance and far infrared rays warm the inside of the substance.

  Part A of FIG. 2 is a detailed view showing a configuration of a spacer for forming a gap between the glass bodies 12 and 13 and bonding the both glass bodies. Reference numeral 15 denotes an adhesive and a double-sided tape, which is attached to a little less than half of the spacer 16 made of a desiccant. Reference numeral 16a denotes a spacer or a desiccant protrusion.

  t1 and t2 are gaps and gaps between the spacer 16 and the glass bodies 12 and 13, respectively. Further, t1 is the thickness of the adhesive of 13, and the adhesive and double-sided tape have a length less than half of the desiccant-containing spacer shown in 16. Reference numeral 16a denotes a protrusion made of only the desiccant. This is a contrivance obtained from the mounting surface because the drying effect of 16 works effectively.

  In addition, as shown in FIG. 2, when the length of the glass members 12 and 13 is different, the beating of 17 beating agents becomes stronger and can contribute to the waterproof effect. The sunlight of 21 absorbs heat rays (near infrared rays) while passing through the glass body of 13, and the far infrared rays that have passed through are reflected to the outside as shown in 24 by the far-infrared reflection effect applied to 12, while I will not come in.

  FIG. 3 is a schematic diagram showing how heat rays (near infrared rays) and far infrared rays are prevented from entering the inside. Reference numeral 34 denotes sunlight, which passes through the outer surface side 31 of the multilayer glass. Reference numeral 36 denotes reflected light that is partially reflected by 31 and does not penetrate inside. Reference numeral 38 denotes a behavior in which 34 heat rays are absorbed while passing through 31.

  Reference numeral 32 denotes a far-infrared reflecting member in which a coating or a transparent film-like member is attached to an indoor glass body. Far-infrared rays that have passed through 31 are reflected by 32 as 39 and are emitted to the outside. Only 37 visible rays enter the room.

  Reference numeral 29 denotes heat rays generated from 31 and near infrared rays. When the glass body 31 absorbs 38 far-infrared rays, heat rays like 29 are emitted. 29 is reflected by 32 members as shown by 30 and returns to the glass member 31, but does not penetrate into 33.

  The gap between the glass members 31 and 33, the gap t0, provides a gap necessary for reflecting the far-infrared rays 39 and the heat rays 29 that have passed through 31 and returning them to 31. For example, since far infrared rays have a wavelength of about 4.0 μm to 25 μm, at least 0.1 mm is sufficient. Therefore, it is only necessary to provide a gap and a hollow portion of one wavelength or more. The multilayer glass body can be made as thin as possible in accordance with the configuration of the bonded portion of the glass members 31 and 33. Therefore, the double-glazed glass according to the present proposal has the same thickness as a normal plate glass and can be easily mounted without a new sash replacement or processing.

  FIG. 4 is a spectral distribution diagram showing the relationship between the light wavelength and the transmittance depending on the material of the glass. 43 is a commonly used clear glass, and 42 is a heat ray absorbing glass. 41 is a characteristic of far-infrared reflective glass.

  As shown in the schematic diagram of FIG. 3, it is effective to use a glass having the characteristic of 42 for the outer glass 31 and a characteristic of 41 for the inner glass 33. In FIG. 4, the point where the characteristics of 41 and 42 cross each other is in the vicinity of 1.8 μm. If a glass body having the characteristics of 41 and 42 is used, at least the transmission of heat rays and far infrared rays can be prevented.

  FIG. 5 shows an example of a multi-layer window glass to which the present invention is applied. Reference numeral 51 denotes a glass window frame, and 52 denotes a sash that closely contacts the glass and the frame. 53a, 53b, 53c, 53d are spacers containing the desiccant described above. In this example, they are arranged at four corners. The periphery of the glass member is sealed with a spacer 53 and a sealing agent 17 and 18 shown in FIG. Therefore, 14 in the figure is in a sealed state.

  The sash 52 is provided with 53 spacers at the four corners of the glass body 54, and the periphery of the 54 is sealed with the 17 seal shown in FIG. . Reference numeral 54 denotes the surface of the double-glazed glass, and in some cases, nitrogen gas or the like is sealed in the gap 14 of the sealed double-glazed glass to prevent fogging. By using the structure according to the present invention, it is possible to construct a thin and strong soundproof and non-fogging glass. In addition, it has shown that the desiccant spacer is arrange | positioned in the position of the dotted-line part of 53.

  FIG. 6 shows a three-dimensional schematic diagram of the multilayer glass according to the present invention. 61 is a glass body facing the outdoor, and 62 is a glass body on the indoor surface. In the figure, t0 is a gap between 61 and 62, and the value of t0 is determined by the spacer containing the desiccant. Since t0 is extremely thin and the thickness of the multilayer glass according to the present invention is not different from that of a conventional plate glass, it is easy to exchange.

  Reference numeral 15 denotes an adhesive, which may be a double-sided tape. If such a structure is placed in the four corners shown in FIG. 5, an effective multilayer glass can be formed. It has excellent effects on shading, soundproofing, noise blocking and strength.

  It should be noted that a crime prevention sensor (not shown) is affixed to the surface of the hollow layer 14 in FIG. Disaster prevention effect is obtained. The destruction sensor has a configuration in which an IC tag is mounted on a transparent ultra-thin glass substrate.

  The break sensor base is several centimeters long, and the conductor is a sensor. When the conductor is broken or damaged, the IC tag reads and detects a change in impedance. Abnormality is detected by an external receiver, terminal adapter, and gateway from the IC tag by weak radio waves.

  The terminal adapter that detects the abnormality is connected to a public line or telephone network. And inform the housekeeper and the person in charge. These responsible persons can know the abnormality by using a mobile phone or a fixed phone. Furthermore, it is possible to recognize whether the abnormal state is an unauthorized intrusion or a disaster, and ask for help from the nearest police or fire department as necessary.

  As described above, the multi-layer glass member according to the present invention blocks heat rays and far infrared rays, so that the indoor living environment becomes comfortable and synergizes with the effect of the air conditioner to save power. In addition, it has a double effect of being easy to handle because it can be constructed thinly while being soundproof and blocking noise.

Second embodiment

  In the present embodiment, a configuration in which a tag computer (RFID: radio frequency identification, IC tag) is attached to the multilayer glass member described in the first embodiment in order to detect destruction of glass materials and unauthorized intrusion will be described. The tag computer is sesame granular and has a size of several millimeters or less. Technically, it has functions necessary for computer processing such as a CPU (Central Processing Unit) and a memory, and cooperates with a network wirelessly.

  Hereinafter, the present embodiment will be described with reference to FIGS. FIG. 7 is a cross-sectional view of the multilayer glass 11 as in FIG. 1, and the RFID 71 is mounted in the space between the glass materials 12 and 13. In FIG. 7, it is affixed on the glass material 13 outside the window. In the figure, reference numeral 72 denotes a destruction sensor and has an antenna function. 73 is a solar cell. If 73 is a passive element, if a solar cell (solar cell) is used as a power source, 71 will operate permanently.

  FIG. 8 shows the RFID units 71, 72, and 73 in a three-dimensional manner as in FIG. 6. The mode that it has arrange | positioned in the outdoor side of the window is shown. It is suitable for storing power because 73 solar cells face external light because they can quickly detect unauthorized glass breakage.

  FIG. 9 shows that an RFID 71 and a solar cell 73 are attached to the glass material of the outdoor side 61 of the multilayer glass 11, and the antenna and breakage detection sensor 72 has a transparent conductive paint or thin film 75 inside the outdoor side glass material 13. This is an example of a coated configuration. With such a structure, the antenna becomes larger and the sensitivity and accuracy of detection of destruction are improved.

  FIG. 10 is a diagram illustrating an internal configuration of the RFID unit. In the figure, reference numeral 81 denotes a system bus that couples each element, and reference numeral 82 denotes an RFID high frequency control unit, which has functions of receiving and transmitting high frequency radio waves. A CPU 83 is an arithmetic processing unit. Reference numeral 84 denotes a program memory which stores a program for processing procedures of the CPU. A memory unit 85 stores calculation results and data fetched from the outside 75.

  Reference numeral 86 denotes a power source, and here, an example in which a solar cell is used has been described. Reference numeral 87 denotes a ground and an earth. Reference numeral 75 denotes an antenna and a break sensor. In the broken talk, when the glass material 11 is broken, the impedance changes. This change is caught by 82 and processed by 83 CPUs. The RFID unit is mounted on the outer side 13 of the multilayer glass 11. When only the indoor side 12 is destroyed, it cannot be detected.

  In preparation for such a case, if 32 applied on the inside of 11 is made into a conductive thin film and combined with 71, it can be detected even if one of them breaks, and the antenna surface becomes large, so the sensitivity is also good. Become.

  FIG. 11 is a diagram showing the configuration and effects of an antenna having an external antenna 75 and a destruction sensor. The radio wave used is generally 13.6 MHZ or 2.45 MHZ. Antennas and sensors are more sensitive and easier to handle if they are small. In order to increase the reach of radio waves, the antenna must be optimally designed.

  The antennas 72 and 75 need to be designed according to the input impedance of the RFID chip 71. As shown in FIG. 11 (a), the + jX component can be generated by the antenna by making it longer (larger) than Ra. By utilizing this characteristic, the reactance component in the IC chip can be controlled. Reactance components including breakdown sensor characteristics can be used.

  FIG. 11B is a schematic diagram of an equivalent circuit when the impedance of the antenna component and the input impedance of the RFID chip are connected.

  Equation 1 is the impedance of the increased antenna and sensor,

  Equation 2 is the input impedance of the RFID chip. By controlling the value of the reactance component JX, the radio wave arrival distance can be increased with a limited output. In FIG. 11B, + JX and Ra in the left part of the figure are antenna and sensor parts, and -JX and Rc on the right part are RFID parts. In order to increase the sensitivity of the sensor and antenna, it is convenient to have a function for controlling these values.

  FIG. 12 shows an example in which RFIDs installed in homes, offices and the like are connected to each other via a wireless network. RFID has a weak antenna output and a short reach. Accordingly, it is necessary to place several gateways (terminal collecting devices) for receiving these output values. Since the reach of radio waves is limited, a method for transmitting to a gateway having a distance by communication between RFIDs is proposed. By doing this, it is possible to reduce the number of gateways and reduce the increase in cost.

  A wireless network (radio network) consists of a number of identical intelligent sensors communicating with each other over a network. In the configuration of FIG. 12, each node (RFID) transmits a message to a neighboring node within a predetermined time, and the message is transmitted from the sensor to the sensor until the message is transmitted to the target node.

  In the case of the present plan, the target node is 91 gateways. In FIG. 12, there are sensors and nodes from RFn1 to nm. In this wireless sensor network, the nodes, i.e. sensors, are static and so are static configurations. In such a configuration, a redundant path that can cover the entire area of the network can be configured.

  In the configuration example of FIG. 12, information is transmitted to 91 via RFn1, RFn6, RFn11, and RFn8. The path passes through ln1, ln2, ln3, ln4, and lnm. When there is a node close to another node and this node has processed something and waits a lot, it immediately searches for another path and informs 91. The transmission path of the path connecting the nodes is freely changed according to the state of the sensor, that is, the node.

  Reference numeral 92 denotes a communication line connected to the 93 website, which is connected to an information communication network such as the 94 Internet network to transmit information to a target facility, terminal device or the like. In the case of a house, there is a breakage of the glass, and the housekeeper can immediately know from a terminal such as a mobile phone device that a bandit has entered.

  FIG. 13 shows an example in which a destruction sensor is installed on a glass window and a front door of a house. 101 is a house and 102 is an installed RFID unit. The glass window is made of energy saving and eco-structure using double glazing. There is a heat insulation effect and a sensor of 102, and information such as detection of breakage, installation location, glass material, installation date, and characteristics is contained in the RFID.

  Information is collected in 96 terminal collection devices (gateways), and information is transmitted from 95 antennas via a public wireless line (mobile phone line). 96 is an indoor communication line from the gateway to the antenna, and 97 is a public radio wave. Information is transmitted from the 92 communication lines to the target terminal equipment from the 93 websites through the 94 Internet network.

  As described above, the multi-layer glass member according to the present invention blocks heat rays and far infrared rays, so that the indoor living environment becomes comfortable and synergizes with the effect of the air conditioner to save power. In addition, it has a double effect of being easy to handle because it can be constructed thinly while being soundproof and blocking noise.

  Furthermore, an RFID can be attached to the inside of the multi-layer glass to detect breakage and breakage, and to quickly construct a notification system at low cost for a housekeeper via a communication information network. RFID has an advantage that a system can be constructed without worrying about the radio wave reach distance because it can transmit and receive information to and from each other as a network sensor system and transmit information to the gateway.
