Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure and a window counter for reducing cold draft from a window.

[0002]

2. Description of the Related Art Not only in cold regions but also in winter, even when the room is heated, it is sometimes cold to receive a cold draft from a window. Therefore, it is conceivable to equip the window with an electric heater or to let the heating air flow along the window surface, but there is a problem that the energy cost and the equipment cost are high.

The present invention allows cold drafts from windows to
It is an object to reduce the energy cost without using the energy cost.

[0004]

[Means for Solving the Problems] The above-mentioned problem is solved in that the window counter provided on the indoor side of the window is a heat storage counter provided with a latent heat storage material, and solar heat is stored in the heat storage counter. It is solved by a window counter characterized by being provided with a structure for reducing cold draft from a window characterized by being provided with a latent heat storage material for storing solar heat.

In this cold draft reduction structure and window counter, when the sun hits the window side during the daytime in winter, the latent heat storage material provided in the window counter accumulates solar heat. Then, when the sun goes down and the outside becomes cold, the solar heat stored in the window counter rises along the window surface in the room, thereby reducing the cold draft from the window.

[0006] In particular, the window counter is in a good position in the sun, and is also installed in a good position to reduce cold draft. Moreover, since it is a counter, the area of the top surface is wide, Therefore, the solar heat can be effectively stored in the daytime, and the stored solar heat can be effectively increased along the window surface on the indoor side after the sun goes down, which is effective for the cold draft in winter. Can be reduced to

According to the reduction structure and the window counter, only the free solar energy is used, and moreover, the window counter is provided with the latent heat storage material, so that the cold draft from the window in the winter can be converted into energy. It is possible to effectively reduce the cost by using a low-priced equipment configuration and to create a comfortable indoor environment.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described with reference to the drawings.

In the cold draft reduction structure of the embodiment shown in FIG. 1, 1 is a window, 2 is a window counter, and this window counter 2 is a heat storage counter provided with a latent heat storage material. The latent heat storage material to be used is determined by considering how much the temperature of the window side on the indoor 3 side rises when receiving the sun during the daytime in winter, but in Hokkaido etc. even if the window side is winter Since it rises to about 40 to 50 ° C when exposed to the sun, in such a case, a latent heat storage temperature of, for example, about 10 ° C may be used. Further, the window counter 2 is composed of a hollow plate having a hard upper surface and a high thermal conductivity and containing a latent heat storage material therein.

In the cold draft reduction structure described above, as shown in FIG. 1B, when the sun hits the top surface 2a of the window counter 2 through the window 1 during the daytime in winter, the window counter 2
Solar heat is stored in the latent heat storage material provided in the. Then, as the sun gets dark and the outside becomes cold, as shown in FIG. 1C, the solar heat 4 stored in the window counter 2 rises along the surface of the window 1 in the room 3, thereby, A warm air curtain is formed on the window,
As shown in (d), the cold draft 5 from the window 1 is reduced.

In particular, as shown in FIG. 1 (b), the window counter 2 is located at a good position in the room 3 where the sun is exposed, and is also located at a good position for reducing the cold draft 5. Moreover, since it is the counter 2, the area of its top surface 2a is large enough to store and dissipate heat. Therefore, during the daytime, as shown in FIG. While the heat is accumulated in the window counter 2, after the sun goes down, the solar heat 4 accumulated in the window counter 2 effectively rises along the window surface 1 on the indoor side 3 side as shown in FIG. Therefore, cold draft in winter can be effectively reduced.

Moreover, since it uses only free solar energy and only the window counter 2 is equipped with a latent heat storage material, cold draft from the window 1 does not incur energy cost in winter. The cost can be effectively reduced by an inexpensive equipment configuration.

Incidentally, in FIG. 2, the window counter 51 is not provided with a latent heat storage material, so that even if the top surface portion 51a of the window counter 51 is exposed to the sun through the window 52 during the daytime, the cold draft 53 at night. Heat is not reduced to reduce the heat generation, and a large cold draft 53 is generated from the window 52 to the room 54.

Although the embodiment of the present invention has been described above, the present invention is not limited to this, and various modifications can be made without departing from the spirit of the invention. For example, the window counter may be a plate-like member 2 that projects into the room as shown in FIG. 1 (a), a counter in the bay window, or a waist wall portion under the waist window. It may be a counter such as a top plate portion of furniture installed along. The point is that the top surface has a size as a counter and can be provided at the lower edge of the window. In addition, there is no particular limitation on the structure for incorporating the latent heat storage material into the window counter, and if the built-in structure is capable of performing sufficient heat storage and heat dissipation to reduce cold draft on the top surface of the window counter 2. Good.

[0015]

Since the present invention is as described above, cold draft from a window can be reduced without energy cost and with a low cost equipment configuration.
