Description

  The present invention relates to a heat insulating inner window that is installed later on a glass window and a kit for making the heat insulating inner window.

  When heating in winter, the proportion of heat entering and leaving the building is roughly 12% for the roof, 9% for the floor, 16% for the outer wall, 12% for ventilation, and 37% for openings such as windows. It is estimated. When cooling in summer, it is estimated that the roof is 9%, the floor is 3%, the outer wall is 7%, the ventilation is 28%, and the windows and other openings are 53%. In this way, heat input and output from openings such as windows occupy a large specific gravity.

  In response to this, another glass window is provided on the indoor side of the glass window by heat insulation modification. However, this double glass type heat insulation that forms an air layer between two pieces of glass does not actually have a heat insulation effect for the investment cost. In fact, even if the inner window sash is provided, there is a complaint that the condensation will continue as usual.

  Patent Document 1 (Utility Model Registration No. 3175074) includes, as a heat insulation modification that can be made inexpensively, a heat insulating frame formed of a foamed synthetic resin and two foamed synthetic resins that can be opened and closed in the heat insulating frame. There has been proposed a heat insulating member for a glass window, which includes a formed heat insulating plate.

  By the way, the heat energy flowing into the room through the window from the outside in summer has a higher rate of heat transfer due to the radiation type than that due to heat conduction or convection. Therefore, it is important to block the entry of heat rays to the indoor side in summer, but in the heat insulating member for glass window of Patent Document 1, this is not sufficiently considered, and there is room for improvement. It was the heat insulation technology to leave.

  The present invention has been made in view of the actual situation of the background art described above, and its purpose is not only to prevent heat transfer by using a heat insulating plate, but also to reflect and radiate heat rays from the outside in summer. The present invention proposes a heat insulating inner window that can positively prevent heat transfer to the indoor side due to heat and reflect the heat rays from the indoor heating equipment etc. to the indoor side in winter and the like to improve the heating efficiency.

It is a figure for demonstrating arrangement | positioning and the effect | action in the summer and winter of the heat insulation inner window which concerns on this invention, Comprising: (a) is a notional elevation sectional drawing of the existing glass window, (b) is related to this invention. (C) is a conceptual elevation sectional view showing the arrangement in the winter of the heat insulating inner window according to the present invention. It is a figure at the time of comprising the heat insulation inner window which concerns on this invention with two heat insulation boards, Comprising: (a) is the conceptual elevation sectional drawing, (b) is the conceptual plane sectional drawing. It is a notional elevation sectional view showing the heat insulating board engaged with the second embodiment of the sill and the duck. It is the figure which showed the lighting type pull provided in a heat insulating board, Comprising: (a) is the disassembled perspective view, (b) is the sectional drawing.

  FIG. 1A is a conceptual elevation cross-sectional view of a general conventional glass window 1. In the glass window 1, the window frame 3 in which the glass 2 is fitted has a lower end supported by a sill 4 and an upper end supported by a duck 5. The threshold 4 and the duck 5 are fixed to the building 6. In the glass window 1 having such a structure, indoor air and outdoor air are in contact with each other across the thin glass 2. As a result, in summer and winter, there is a large temperature difference between indoors and outdoors, and a large flow of thermal energy is generated by heat conduction in the glass.

  Moreover, in order to make the window frame 3 slidable, a narrow gap (not shown) exists between the window frame 3 and the sill 4 and between the window frame 3 and the duck 5. As a result, although it is slight, an air flow a occurs between the room and the outside through the gap. That is, hot air flowing into the room from the outside in the summer increases the room temperature, and warm air flows from the room to the outside in the winter to decrease the room temperature.

Usually, the glass 2 of the glass window 1 passes a heat ray. As a result, in the summer, the heat ray b reaches the room through the glass 2 from the outside, and the room temperature is raised by the radiant heat. In winter, when the indoor heater is of a type that generates heat rays such as far-infrared rays, the heat ray c from the heater also flows outside through the glass 2 and is heated other than the type that generates heat rays. Even when the appliance is used, the heat rays c from the heated inner wall, furniture, and other articles also flow out to the outside through the glass 2, and the heating efficiency is lowered. Moreover, although heat ray blocking glass is also used as a glass material, the glass plate itself becomes high in summer, and the indoor temperature is raised by the radiant heat. Further, the conventional glass window structure has a large amount of condensation due to a temperature difference between indoor and outdoor in winter.
The heat ray means near infrared, middle infrared, or far infrared (for example, light having a wavelength range of about 800 to 3000 nm), and includes part of visible light.

  Thus, in the general conventional glass window 1, the heat conduction of the window part, the air flow a passing through the gap between the window frame 3 and the sill 4 and the duck 5 and the heat rays b and c passing through the glass, etc. Therefore, the cooling efficiency in summer and the heating efficiency in winter are poor.

  FIGS. 1B and 1C are conceptual elevational sectional views showing the arrangement of the heat insulating inner windows according to the present invention in summer and winter, respectively. In FIGS. 1B and 1C, the members of the existing glass window are denoted by the reference numerals of the corresponding members in FIG. The same applies to embodiments described later. The heat insulating inner window 20 according to the present invention can be retrofitted on the indoor side of the existing glass window 10.

  The heat insulating inner window 20 according to the present invention includes a heat insulating plate 21 made of foamed synthetic resin. One plate surface of the heat insulating plate 21 is formed on a plate surface 21a that easily reflects heat rays, and the other plate surface is formed on a plate surface having different characteristics from the plate surface that easily reflects heat rays. Specifically, the other plate surface is functionally preferably a plate surface 21b that easily absorbs heat rays, and preferably by design, preferably a plate surface of a color different from the plate surface that easily reflects the heat rays, or cost. Particularly preferred is a form in which the heat insulating plate is exposed as it is. The configuration of the heat insulating plate 21 will be described in detail later.

The heat insulating inner window 20 according to the present invention is provided by attaching a sill 22 and a duck 23 to the building 6 on the indoor side of the existing glass window 10 and supporting the lower end and the upper end of the heat insulating plate 21 to the sill 22 and the duck 23, respectively. It is attached to the building 6.
In this embodiment, the sill 22 and the duck 23 are realized as plate-like members that engage with the slits 21c and 21c formed in the lower end surface central portion and the upper end surface central portion of the heat insulating plate 21, respectively.

  In the summer, as shown in FIG. 1 (b), the plate surface 21a that easily reflects heat rays faces the outside (the glass window side), and the other plate surface has different characteristics from the plate surface that easily reflects the heat rays. As the surface, for example, the heat insulating plate 21 is arranged such that a plate surface 21b that easily absorbs heat rays faces the room. On the other hand, in winter, as shown in FIG. 1 (c), the heat insulating plate 21 is provided such that the plate surface 21a that easily reflects heat rays faces the room, for example, the plate surface 21b that easily absorbs heat rays faces the outdoors. Be placed.

  Since the existing glass window 10 is in contact with the outside air and there is a narrow gap between the sill 4 and the duck 5, there is air in and out. As a result, air convection also occurs in the intermediate space A defined between the glass 2 and the heat insulating inner window 20. However, since the intermediate space A and the room are thermally blocked by the heat insulating plate 21 made of foamed synthetic resin having low thermal conductivity, the flow of heat energy into the room is small. Further, the inflow of heat energy from the intermediate space A due to convection into the room can be reduced. For example, by utilizing the elasticity of the heat insulating plate 21 made of foamed synthetic resin, the heat insulating plate 21 and the sill 22, and the heat insulating plate 21 and the duck 23 can be brought into close contact with each other, thereby making it easy to reduce the entry and exit of air.

  In the summer, the heat insulating plate 21 is arranged so that the plate surface 21a that easily reflects the heat rays faces the outside, so that the heat rays from the outdoors in the summer (mainly the heat rays from the sun S) b pass through the glass 2. However, the heat ray of the heat insulating plate 21 is reflected by the plate surface 21a that easily reflects, and the flow of heat energy into the room due to radiation can be prevented.

  In winter, the heat insulating plate 21 is arranged so that the plate surface 21a that easily reflects heat rays faces the room, so that the heat rays c such as far-infrared rays from the heater D etc. reflect the heat rays of the heat insulating plate 21. It is easily reflected by the plate surface 21a, and the sensible temperature in the room can be raised by radiation to improve the heating efficiency. Further, in the preferred embodiment shown in FIG. 1 (c), the plate surface 21b that easily absorbs heat rays of the heat insulating plate 21 faces the outdoors, so that it is easy to absorb heat rays when the sun is shining. The plate surface 21b absorbs the heat ray b of sunlight and stores heat. As a result, the temperature of the surface of the heat insulating plate toward the outside is increased, and this is described later in which two heat insulating plates are provided that can be opened and closed by raising the temperature of the intermediate space A and sliding it left and right. In the two types of heat-insulating inner windows, in winter, during the daytime, and in the day when the sun is strong, by opening the heat insulation board a little, it acts in the direction of raising the room temperature and can efficiently use natural energy for room temperature adjustment. .

  As described above, the heat insulating inner window 20 according to the present invention dramatically improves the cooling effect in summer and the heating effect in winter by inverting the heat insulating plate 21 according to the season and arranging it on the indoor side of the glass window 10. Can be made.

  Although the heat insulation inner window 20 according to the present invention can be constituted by a single heat insulation plate, it can also be constituted by a plurality of heat insulation plates. 2A and 2B are diagrams in the case where the heat insulating inner window 30 according to the present invention is configured by two heat insulating plates 31 and 32, wherein FIG. 2A is a conceptual elevation cross-sectional view thereof, and FIG.

The two heat insulating plates 31 and 32 are respectively formed on plate surfaces 31a and 32a that easily reflect heat rays, and the other plate surfaces are preferably plate surfaces 31b and 32b that easily absorb heat rays. Is formed. In summer, the same effect as described in FIG. Further, the same effect as described with reference to FIG. Further, in the case of this embodiment, the time and heat insulating plates 31 and 32 can be opened by sliding along the sill 33 and the duck 34 for ventilation, daylighting and the like.

  In FIG. 1 and FIG. 2, the sill and the duck are realized as plate-like members that engage with the slits formed at the center of the upper and lower end surfaces of the heat-insulating plate, but the heat-insulating plate is interposed between the two plate-like members. It can also be realized in a pinched format. FIG. 3 is a conceptual elevation sectional view showing a heat insulating plate engaged with a sill and a duck according to the second embodiment.

And the upper end of the heat insulation board 31 is clamped between the plate-like members 42a and 42b, and the upper end of the heat insulation board 32 is clamped between the plate-like members 42b and 42c, whereby the upper ends of the two heat insulation boards 31, 32 Support.
According to the sill 41 and the duck 42 according to the second embodiment, it is not necessary to form slits on the upper and lower end surfaces of the heat insulating plate, and the lower end and the upper end of the heat insulating plate are supported in a covered state. Further, since it is possible to prevent damage such as chipping and cracking of the heat insulating plate, it is excellent in durability, and since the air flow from the gap between the sill and the duck can be further reduced, the airtightness is also excellent.

  In the present invention, a handle can be provided for sliding the heat insulating plate. FIG. 4A is an exploded perspective view of an example in which a daylighting puller is provided on the heat insulating plate, and FIG. 4B is a cross-sectional view thereof.
