Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a structure for reducing cold draft from a window and a window counter.
[0002]
[Prior art and problems]
Not only in cold areas, but in the winter, you may feel cold by receiving a cold draft from the window even if you heat the room. Therefore, it is conceivable to provide an electric heater on the window side or to flow the heating air along the window surface, but there is a problem that the energy cost and equipment cost are high.
[0003]
This invention makes it a subject to reduce the cold draft from a window by an inexpensive equipment structure, without incurring energy cost.
[0004]
[Means for Solving the Problems]
The above problem is 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. The problem is solved by a window counter characterized in that a cold draft is reduced, and a latent heat storage material that stores solar heat is provided.
[0005]
In the cold draft reducing structure and the window counter, when the sun is inserted into the window during the winter daytime, the latent heat storage material provided in the window counter stores the solar heat. When the sun goes down and the outside gets 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 a perfect place to hit the sun, and it is placed in a perfect position to reduce the cold draft. Can effectively store solar heat and, after sunset, can effectively increase the stored solar heat along the indoor windows, effectively reducing cold drafts in winter be able to.
[0007]
And according to this reduction structure and the window counter, only the free solar energy is used, and the window counter is only equipped with a latent heat storage material, and the cold draft from the winter window is costly. Therefore, it can be effectively reduced by an inexpensive equipment configuration, and a comfortable indoor environment can be formed.

DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described with reference to the drawings.
[0009]
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 composed of a heat storage counter provided with a latent heat storage material. The latent heat storage material to be used is determined in consideration of how much the temperature of the window on the indoor 3 side will rise when receiving the sun during the winter day. Since the temperature rises to about 40 to 50 ° C. when the sun hits, in such a case, a latent heat storage temperature of about 10 ° C. may be used. Moreover, the window counter 2 consists of what contained the latent heat storage material in the inside of the hollow plate with a hard upper surface and high heat conductivity.
[0010]
In the cold draft reduction structure described above, as shown in FIG. 1 (b), when sunlight hits the top surface 2a of the window counter 2 through the window 1 during the daytime in winter, solar heat is applied to the latent heat storage material provided in the window counter 2. Is stored. When the sun goes down and the outside gets cold, the solar heat 4 stored in the window counter 2 rises along the surface of the window 1 in the room 3, as shown in FIG. A warm air curtain is formed in the window, and the cold draft 5 from the window 1 is reduced as shown in FIG.
[0011]
In particular, as shown in FIG. 1 (B), the window counter 2 is a perfect position where the sun hits in the room 3, and is installed in a perfect position for reducing the cold draft 5, Moreover, since it is a counter 2, the area of its top surface 2a is large enough to store and dissipate heat, so that solar heat can be effectively used in the daytime as shown in FIG. As shown in FIG. 1 (c), the solar heat 4 stored in the window counter 2 rises effectively along the window surface 1 on the side of the room 3 after sunset. And can effectively reduce the cold draft in winter.
[0012]
Moreover, since it uses only free solar energy and is provided with a latent heat storage material in the window counter 2, a cold draft from the window 1 in the winter is inexpensive without incurring energy costs. It can be effectively reduced by the equipment configuration.
[0013]
Incidentally, in FIG. 2, the window counter 51 is not provided with a latent heat storage material. Therefore, even if the sun hits the top surface 51a of the window counter 51 through the window 52 in the daytime, the cold draft 53 is reduced at night. Such heat dissipation is not performed, and a large cold draft 53 is generated from the window 52 to the room 54.
[0014]
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 wall-like one 2 that protrudes into the room as shown in FIG. 1 (a), may be a counter in the bay window, or a waist wall portion below the waist window It may be a counter such as a top part of furniture installed along the door. In short, it is only necessary that the top surface has a size as a counter and is provided at the lower edge of the window. In addition, there is no particular restriction on the structure of incorporating the latent heat storage material into the window counter, so long as it has a built-in structure that can store and release heat sufficiently to reduce the cold draft at the top surface of the window counter 2. Good.
[0015]
【The invention's effect】
Since the present invention is as described above, the cold draft from the window can be reduced with an inexpensive equipment configuration without incurring energy costs.
