Description

[Detailed description of the invention] Industrial application field This invention relates to an insulated door storage door bag that also serves as a solar heating system.

Conventional technology and its problems Conventionally, water heating equipment is generally known as a solar heating system, but this is installed on the roof and circulates water indoors and outdoors, and the heat from the hot water obtained by the water heating equipment is transferred indoors. Since it is emitted by air, it requires incidental equipment such as piping, pumps, and radiators, and its construction is troublesome.

The purpose of this invention is to provide an excellent door pocket that also serves as a heating device, which solves the above-mentioned problems.

Means to Solve the Problems In the insulated door storage door that also serves as a heating device, the outer wall of the door is composed of a transparent top plate and a heat storage body with a solar heat absorbing film on the outer surface. An insulated door is housed inside, and when the insulated door is closed, the heat storage element on the outer wall of the door is exposed indoors.

As the transparent top plate, a transparent glass plate is generally used, but transparent synthetic resins such as acrylic resins can also be used. Concrete, brick, etc. are commonly used as the heat storage body, but in order to increase the heat storage rate, it is preferable to intersperse a large number of sealed containers with water or latent heat storage material in the concrete. Suitable latent heat storage materials include sodium sulfate decahydrate, calcium chloride hexahydrate, sodium phosphate dodecahydrate, caustic soda monohydrate, sodium thiosulfate pentahydrate, paraffin, and polyethylene glycol.
The material for the container is preferably a thermoplastic synthetic resin such as polyethylene, since the container is filled with contents and then heat sealed. Suitable shapes for the containers include spherical, potbellied, and cylindrical shapes, and in order to evenly scatter them in the concrete, it is best to make them as small as possible. The inner surface of the heat storage body is painted white or black in order to promote heat dissipation, but a metal plate such as an aluminum plate with an embossed pattern may also be pasted to serve as the interior decoration. In seasons when heating is not required, a heat insulating shield is placed on the outside of the outer wall of the door pocket. The insulation shield is
It may be detachable from the door pocket, it may be in the form of a hinged door or a sliding door, it may be a shutter or blind that moves up and down, and it may even be provided with an eaves above the door pocket. Insulating doors are made of synthetic resins such as urethane and styrene, or glass wool.

Example This invention will be explained below with reference to the drawings.

Embodiment 1 FIG. 1 shows one embodiment of this invention, in which a heating device-cum-insulating door storage door bag B1 is provided on both sides of a glass door A.

This insulation door storage door bag B1 that also serves as a heating device has a door bag outer wall 1 that has a transparent top plate 2 and a solar heat absorbing film 3 on the outer surface.
A heat storage body 4 is provided with a heat storage body 4, and a heat insulating door 5 is housed on the indoor side of the door bag outer wall 1.
When the heat insulating door is closed, the heat storage body 4 of the door bag outer wall 1 is exposed to the interior I.

The peripheral wall 6 of the door pocket B1 has a vertical rectangular frame shape, and is provided with a cutout 7 on the glass door A side for inserting and removing the heat insulating door 5. This peripheral wall 6 may be made of aluminum extrusion and may be integrated with the sash of the glass door A. Appropriate heat insulation treatment is applied to the peripheral wall 6. The heat insulating doors 5 are drawn out from the double-door bag B1 to the indoor I side of the glass door A in a continuous manner. The heat storage body 4 is a water-tight spherical container 4 the size of a ping pong ball in concrete 4a.
b are scattered in large numbers. A slight space 8 is provided between the transparent top plate 1 and the heat storage body 4.

The door pocket B1 is used as a heating device in the following manner. That is, during the day, the heat insulating door 5 is opened and is housed in the door pocket B1, as shown by the solid line in FIG. Sunlight from outside O passes through the transparent top plate 2 of the outer wall 1 of the door pocket and hits the solar heat selective absorption film 3.The solar heat selective absorption film 3 absorbs heat well but radiates little heat. As a result, sufficient heat is stored in the heat storage body 4. Therefore, when the heat insulating door 5 is closed at night as shown by the chain line in FIG.
Since it is exposed toward the indoor I, the heat stored in it is radiated to the indoor I, heating the indoor I. Of course, heating can be performed as described above even during the daytime, if necessary.

Embodiment 2 Fig. 2 shows another example of the embodiment of this invention, in which an insulated door storage door bag B2 that also serves as a heating device is present only on one side of the glass door A, and this door bag b2 is is designed to accommodate two heat insulating doors 5.

The width of the peripheral wall 16 is longer than the peripheral wall 6 of the door bag B1 in Example 1 by 51 heat-insulating doors, and the notch 17 has a width that can accommodate 52 heat-insulating doors. The two heat insulating doors 5 are in a sliding configuration as shown by the chain lines in FIG.

Those shown in FIG. 2 with the same reference numerals as in FIG. 1 are the same members and parts as in FIG. 1, and their explanations will be omitted.

The function of the door pocket as a heating device in the second embodiment is as follows.
It is exactly the same as that of the first embodiment.

Effects of the Invention According to the insulated door/storage door which doubles as a heating device using solar heat according to this invention, it is possible to heat the indoor room I only by solar heat as described above.

Since the heat storage body 4 has the solar heat absorbing film 3 on its outer surface, it can sufficiently store the heat necessary for heating.

Moreover, the solar heat absorbing film 3 is covered with the transparent top plate 2 and is not exposed to the outdoors, so there is no fear of damage and it has durability.

Furthermore, since this heating system itself is a door pocket that is part of the building, not only is there no need for incidental equipment, it is easy to construct on-site, and its structure allows it to be made into a unit, making it possible to mass-produce it in a factory. Cost will be lower.

Furthermore, the above-mentioned heat-insulating door has the advantage that it can also perform the same role as a conventional storm door.
