JPH0197786A - Window using semitransparent heat-insulating material - Google Patents

Abstract

PURPOSE: To shut off outside air which is hot during the summer and cold during the winter so as to readily attain comfortable room temperature by providing glass sliding doors at upper and lower stages, and providing sliding doors having a semitransparent heat insulating member, inside the glass sliding doors. CONSTITUTION: A glass sliding door is divided into upper and lower parts such that the narrow, upper glass sliding door 1 and the wide, lower glass sliding door 2 are provided at upper and lower stages. Sliding doors 3 made of a semitransparent heat insulating member with a semitransparent heat insulating member 4 fitted therein are provided on the indoor sides of the glass sliding doors. The semitransparent heat insulating member is, e.g. a plate made of a heat insulating material which is milky white in color and 2 to 3 mm thick, having the property of allowing light to easily pass through while keeping out heat.

Description

[Detailed description of the invention] <Industrial application field> The present invention relates to the structure of windows in buildings.

<Conventional technology> Conventionally, the structure of windows in buildings was to fit sliding glass doors into the window frame, and then install curtains or blinds on the inside of the room to protect them from direct sunlight or to cover them.

Measures to solve the problem> As a result, the temperature increases near the window on a hot summer day, and the temperature decreases near the window on a cold winter day, which affects the indoor temperature, making it hotter in the summer and hotter in the winter. It was cold.

Therefore, if you can lower the temperature near the window on hot summer days and raise it on cold winter days, you will be able to make the indoor environment more comfortable to live in, and you will also be able to cool down! v5 costs will be reduced.

Here are some ways to solve these problems: For this reason, if you install a door with translucent heat insulating material on the inside of the conventional glass door, you can maintain the brightness of the room.
It blocks out the hot sunlight in summer and the cold outside air in winter.

Function> and <Example> Based on the example shown in Fig. 1, a more detailed explanation will be given below.The sliding glass door is divided into upper and lower parts, and the upper sliding glass door (1) with a narrower width is placed in the upper part, and the upper sliding glass door (1) is placed in the lower part. Install a wide lower glass sliding door (2). Further, on the indoor side thereof, a sliding door (3) made of a semi-transparent heat insulating material fitted with a semi-transparent heat insulating material (4) is provided.

Here, the term "semi-transparent heat insulating material" refers to a plate of heat insulating material that is milky white in color and 2 to 3 mm thick, and is made of a material that allows light to pass through well but blocks heat.

The method of use will be explained below with reference to Figures 2 to 5. First, during the summer day, as shown in Figure 2, the lower glass sliding door (2) is closed, and the upper glass sliding door (2) is closed. 1) Open the
Close the semi-transparent insulation sliding door (3).

In this way, the air between the lower sliding glass door (2) and the translucent insulating sliding door (3) becomes hot and escapes through the upper sliding glass door (1) as shown by the arrow. The temperature of the air is lower than that of the outside air, and the heat is further blocked by the translucent heat insulating material (4), so the heat from the hot outside air is not transmitted into the room and the area near the window does not get hot.

Also, since the translucent insulation material (4) allows light to pass through well, the room will not become dark even when the door is closed.

Secondly, as shown in Figure 3, how to use it at night in summer is to use the upper sliding glass door (1) and the lower glass sliding door (2).
If you open all the sliding doors (3) made of translucent insulation material, the cold outside air at night will come into the room. In this case, install a screen door to prevent insects from entering.

Thirdly, as shown in Figure 4, how to use the upper glass sliding door (1) and the lower glass sliding door (1) during warm days in winter.
If you close 2) and open the sliding door (3) made of translucent insulation material,
Warm winter sunlight shines into the room, making it warmer.

Fourthly, when it is cold in winter, as shown in Figure 5, the upper sliding glass door (1), the lower glass sliding door (2), and the semitransparent insulation sliding door (3) are all used. If you open it, the cold air from outside will be blocked from entering the room.

<Effects of the Invention> As described above, the present invention provides a window with two sliding glass doors, an upper and a lower one, and further provides a sliding door made of translucent heat insulating material on the indoor side.
By using a simple method to open and close these sliding doors according to changes in outside air temperature, you can block out hot outside air in summer and cold outside air in winter, easily maintain a comfortable room temperature, and reduce heating and cooling costs.
It also has the effect of not making the room dark.
