Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a window assembly that is installed in a window of a building.

A window assembly conventionally attached to a window of a building consists of a window frame and a window glass attached to the window frame.

Window assemblies, which are typically installed in the windows of buildings, serve a variety of important functions. Typical examples include lighting, ventilation, ventilation, temperature control, contact with the outside world, entrances and exits, emergency entry, and escape exits. Window assemblies also serve as important accents on the exterior and interior of buildings.

However, as mentioned above, the window assembly has poor insulation performance because it consists of two parts, the window frame and the window, and a large amount of heat loss occurs through the window assembly when heating a room, resulting in wasted thermal energy. There were drawbacks.

In addition, the thermal insulation performance of the window assembly is determined by the thermal conductivity (K(!a4/@
For example, in the case of a single glass sash in an office building, it is approximately 5.5 to 10 Kcat.
/1rL2'QHr, the heat transmission coefficient of the wall of a typical office building (Kca/7g2℃Hr) is approximately 0-5 to 1
．． The value was 5 to 20 times worse than OKaat/m2°CHr, which was a large imbalance with respect to the heat insulation performance of the wall. Therefore,.

/'- When designing a heating system for a building equipped with such a window assembly, heat loss must be calculated for windows and walls individually based on the heat transfer coefficients mentioned above, so as not to reduce the heating effect at the window. , the capacity of the heating equipment must be determined so that the amount of heat equivalent to the heat loss is supplied to each part, and appropriate heat distribution and heat control must be added to this, making heating design extremely difficult and complicated. Conventionally, in order to improve the insulation performance of such window assemblies as much as possible, the window glass was double-glazed, and if the window frame was made of metal such as aluminum, the flow of heat from the window frame was blocked. Therefore, there are double glass sashes in which the window frame is divided into an indoor part and an outdoor part and a hard plastic band is interposed between the two, and a double glass sash is made in which the window frame is divided into three layers and the window frame is divided in the same way and a hard plastic band is interposed between the two. Triple-glazed satsushi is used. However, even with double glass sash, the heat transmission coefficient is about 2-4 to 5. OKca7/H2
°CHr,) Even with ripple glass sash, the heat transmission coefficient is about 1.
8-2. Q Kcat/m2°QHr: 1, wall approximately 0.5~'1. This value is still about 2 to 6 times worse than the heat transfer coefficient of OKcat/m”°CHr, and even if the waste of thermal energy can be reduced to some extent, the imbalance with the insulation performance of the wall still remains unresolved. In addition, as the window glass is made double or triple layered and hard plastic strips are interposed in the window frame, the structure becomes complicated and expensive, and the number of window glasses and the number of hard plastic strips becomes more complicated. Increasing the number of products any further was reaching its limit, both structurally and economically.

Furthermore, in addition to the poor insulation performance described above, conventional window assemblies also have the disadvantage of being susceptible to condensation due to the temperature difference between indoor and outdoor air.

The purpose of the present invention is to eliminate the above-mentioned conventional drawbacks, provide a window assembly that has excellent heat insulation performance, can reduce thermal energy loss, facilitates heating design, and is less likely to cause condensation. It is to be.

According to the present invention, a far infrared ray generator made of a ceramic particle layer is installed along the entire length of one side of the window frame other than the outdoor side, and the far infrared rays emitted from the generation surface are applied to the window glass. A window assembly is provided, characterized in that it is mounted to be illuminated.

Preferred embodiments of the present invention will be explained below with reference to the drawings.
In FIGS. 1 and 2, a window assembly according to a first embodiment of the present invention is generally designated by the reference numeral 2.
The window frame 8 includes a fixed outer frame 4 attached to a wall of a building, and a movable inner frame 6 hinged to one side of the outer frame 4 so as to be freely openable and closable. A window glass 10 is attached to the inner frame 6 of the window frame 8 in a normal manner, and the upper side 1 of the outer frame 4
20 A mounting box 16 is fixedly installed on the indoor side surface 14,
Inside the mounting box 16, along the entire length of the upper side 12 of the outer frame 4, a far infrared ray generator 22 is provided with a far infrared ray generating surface 20 made of a ceramic particle layer 18 (see FIG. 6). The window 20 is attached to the glass surface of the 2s 10 at almost a right angle.

As shown in an enlarged cross-sectional view in FIG.
0 is made of a material with good thermal conductivity, such as a steel plate.

The outer surface of the substrate portion 24 of the casing 300 is coated with the far-infrared emitting ceramic particle layer 18 to constitute the far-infrared generating surface 20, and the inner surface is coated with the sheet heating element 32.
is glued. As the planar heating element 32, a heating element 32a made of glass fiber cloth coated with a carbon heating element (dotite) is coated with a polyester sheet (321) 1320 on both sides of the heating element 32a.
The heat generating element 32 can be
Electrodes 32d are provided at both ends of a.

32θ is formed. The electrodes 3211 and 328 are connected to a power source via wiring and electric cords (not shown). Further, the electrodes 32a and 32θ are connected to the power source,
For switch-off operation and temperature regulation, it can be connected to a controller that cooperates with a thermostat, not shown.

The planar heating element 32 may be provided with a safety device such as a device for preventing excessive temperature rise. A heat insulating material 34 made of glass wool, for example, is provided below the sheet heating element 32, and the heat insulating material 34 is held by a cover 36 fixed to the side plate portions 26, 28 of the casing 30 with screws or the like. .

As shown in an enlarged view in FIG. 4, the ceramic particle layer 1B is preferably formed by coating a heat-resistant adhesive 36 on the substrate portion 24 of the casing 3o, and placing ceramic particles 38 on top of which some of the ceramic particles 38 are coated with the adhesive. It is embedded so as to protrude from the surface of 6.

As the heat-resistant adhesive 36, preferably an epoxy adhesive is used, and a heat-resistant paint can also be used.

As the ceramic particles, silica-based silicic acid coarse particles (silica sand) are preferably used, and other ceramic materials such as zirconia-based, titania-based, alumina-based, etc. can also be used.

To explain the operation of the window assembly 2 of the above-described embodiment, when the far-infrared generator 220 and the planar heating element 32 are energized and the ceramic particle layer 18 is heated to a temperature of about 80 degrees Celsius, the ceramic particles 38 Due to its properties, it efficiently converts thermal energy into far-infrared energy, and emits far-infrared rays with a wavelength of 8 to 10 microns at a high density.

Also, at this time, some of the ceramic particles 38 are attached to the adhesive 3.
6, far infrared rays are emitted in various directions from the surface of the protruding portion constituting the polyhedron of the ceramic particle 38. Therefore, far-infrared rays are emitted in front of the far-infrared ray generating surface 20 over a wide angular range of about 160 degrees at most.

Therefore, the window glass 10 of the window assembly 2 is irradiated with a considerable amount of far infrared rays. On the other hand, glass does not transmit far infrared rays, part 2
It has the property of absorbing 0% or more and re-radiating it. Therefore, the far infrared rays irradiated to the window glass 10
More than 0% is absorbed, warms the glass surface, and is re-radiated.

Due to the operation of the window assembly 20 as described above, the window assembly 2
When the is installed on the window of the building, the window glass 1 of the window assembly 2
0 and the radiant temperature of the window frame 8 to a maximum of 5.
It can be raised by 5℃. Therefore, heat loss in the window assembly 2 is almost completely self-compensated, and people in the vicinity of the window do not feel cold even if the heating in that area is not particularly strong. Also, the energy form used at this time is radiant energy,
The initial generation of this radiant energy takes place in the ceramic particle layer 18, which converts thermal energy into radiant energy extremely efficiently, and the window glass 1o absorbs and re-radiates more than 90% of the irradiated radiant energy. This can be done by applying a small amount of thermal energy to the ceramic particle layer 18 to compensate for the amount of heat escaping to the outside through the solid body 2, by arranging special heating equipment near the window, or by installing hot air outlets. Energy waste can be significantly reduced compared to when heating in that area is particularly strengthened, such as by installing a large number of heating units. Furthermore, the ceramic particle layer 18 is safe and easy to handle because it only needs to be heated to a low temperature of about 80 degrees.

Note that when the amount of heat escaping outdoors through the window assembly 2 during heating is supplemented with far-infrared energy from the far-infrared generator 22,
By determining the capacity of the far-infrared generator 22 so that the proportion of heat escaping outdoors is almost the same as the proportion of heat escaping outdoors through the wall, the heat transfer coefficient between the window assembly 2 and the wall can be substantially reduced. It is possible to make the thermal insulation performance the same.

As a result, the outer wall of a building can be regarded as a wall with uniform insulation performance regardless of whether there are windows, making heating design extremely easy9 and installation of heating equipment also easy.

Further, in the window assembly 2, due to the heating effect of far infrared rays irradiated to the window glass 10, almost no dew condensation occurs even if there is a temperature difference between indoors and outdoors.

Furthermore, according to the window assembly 2 of the above embodiment, a part of the far infrared rays emitted from the ceramic particle layer 18 of the far infrared generator 22 is directly irradiated into the room and can be used for heating. This makes it possible to further reduce energy consumption.

5 and 6 illustrate a second embodiment of the window assembly of the present invention. The window assembly, generally designated 50 in this embodiment, includes a fixed outer frame 52 attached to a wall of a building, and a movable frame 52 hinged to the outer frame 52 on one side so as to be openable and closable. Two window gases 58 and 60 are attached to the inner frame 54 of the window frame 56 in a normal manner to form a double glass sash. For mounting the window glass 58, 60 on the upper side 62 of the inner frame 54, a mounting box 66 is fixed in a recess 64 between the parts.
A far-infrared generator TO is provided with far-infrared ray generating surfaces 68 consisting of the upper two particle layers along almost the entire length of the generating surface 6.
8 is attached to the glass surface of the window glass 58, 60 at approximately right angles.

The specific structure of the far-infrared generator 10 is substantially the same as the far-infrared generator 22 of the first embodiment, so a description thereof will be omitted.

In the window assembly 50 of this embodiment, the far-infrared generator 7
Almost all of the far infrared rays from 0 are transmitted through the two window glasses 58.
．． 60 irradiated. The irradiated far infrared rays are mutually absorbed by the window glass 58 and 60 without passing through the window glass.
The radiant temperature of the entire window assembly 50 is increased by reflection and re-radiation, and the temperature of the air trapped inside the assembly (dry bulb temperature) is reduced to the indoor heating air temperature (dry bulb temperature).
equal to or higher than that. As a result, heat loss of indoor heating air due to the window assembly 50 is completely prevented. Therefore, this embodiment also has the same characteristics as the first embodiment.
It is possible to improve insulation performance, save energy, simplify heating design, and prevent condensation.

Furthermore, in this embodiment, almost all of the far infrared rays from the far infrared generator 70 are irradiated onto the window glass, so the ratio and efficiency of the far infrared energy irradiated onto the window glass is different from that in the first embodiment. The capacity of the far-infrared generator 70 can be reduced to further reduce the amount of thermal energy applied to the ceramic particle layer, which is different from that of the first embodiment because of its high heat resistance and the double glass sash structure. can save energy.

Although the far-infrared generators 22.70 are attached to the upper sides of the window frames 8 and 56 in the first and second embodiments, the invention is not limited to this, and in particular in the second embodiment. The far infrared ray generator 22.70 is mounted on the side of the window frame without getting in the way and is sufficiently durable for practical use. 10, 58, 60 was mounted so that it was perpendicular to the glass surface, but such mounting is not limited to the angle. For example, in the first embodiment, the far infrared ray generating surface 20 In the second embodiment, the far-infrared ray generating surface 68 can be mounted slightly toward the window glass 60 on the indoor side.
In short, it is sufficient that the window glass 10°60 is mounted so that the far infrared rays emitted from the generation surface 20°68 are irradiated onto the window glass 10°60.

As is clear from the above, according to the window assembly of the present invention, the entire length of the window frame (along the
A far-infrared generator equipped with a far-infrared ray generating surface made of a ceramic particle layer was installed in such a way that the far-infrared rays m emitted from the nucleation surface were irradiated onto the window glass, so the window glass did not emit far-infrared rays. It is possible to improve the heat insulation performance of the window assembly by actively supplementing the amount of heat absorbed and heated and escaping to the outside through the window assembly during heating. This can be done by applying a small amount of thermal energy to the ceramic particle layer of the far-infrared generator, which reduces energy loss during heating and further increases the capacity of the far-infrared generator. By appropriately determining the heat insulating performance of the window assembly, it is possible to make the heat insulating performance of the window assembly almost the same as that of the wall, thereby facilitating heating design.

Furthermore, dew condensation can be prevented by the heating effect of far infrared rays irradiated onto the window glass.
