Description

[Detailed Description of the Invention] The present invention relates to the structure of a flower box that can form a heat storage device that fits well and has excellent thermal efficiency by incorporating a heat storage tank below the flower box and providing a cover on the outdoor surface of the flower box.

Conventional devices that use solar heat to air condition indoors include powered air conditioners that use pumps to circulate a heat medium between a solar heat collector installed on the roof and a radiator installed indoors. There are so-called passive heat storage devices that simply store heat storage liquid in a heat storage tank without using power to circulate the heat medium. Since the heat storage tank was installed as a heat storage tank and absorbed and radiated heat at the same time, its installation reduced the indoor space and made the interior unattractive, and it was not possible to achieve efficient air conditioning. There wasn't.

This invention incorporates a heat storage tank below the flower box that protrudes from the outer wall of the building, and also provides a cover that can be attached to and separated from the outdoor surface of the flower box, making it possible to fit it in while making use of the space of the building, while also improving thermal efficiency. With the aim of providing a structure of a flower box that can form an excellent heat storage device, one embodiment thereof will be described below with reference to the drawings.

In the figure, the structure of the present invention includes a heat storage tank 2 installed on the floor below a flower box B for placing flower pots, etc., which protrudes from the lower edge of a window on the outer wall of a building; A cover 4 that covers the surface.

The heat storage tank 2 is formed of a metal plate such as a steel plate, an aluminum plate, or a synthetic resin, and has a rectangular cross section, and is formed as a water tank in which the heat storage liquid R can be sealed. It is formed in 6 or multiple stages of inclined pieces tilted at right angles to the average solar radiation angle of the sun, increasing the area for absorbing solar heat, and
The interior surface has a plurality of fins 8 that are bent into a substantially U-shape.

Furthermore, there is a vertical gap g19g inside the heat storage tank 2.
A partition plate 10 is vertically attached to the side wall of the heat storage tank 2 to separate the heat storage tank 2 from the heat absorption part 12 on the front side and on the rear side. A check valve 16 is provided in the upper gap g1 to allow water to flow freely from the heat absorbing part 12 to the heat radiating part 14, and a check valve 16 is installed in the upper gap g1 to allow water to freely flow from the heat absorbing part 12 to the heat radiating part 14. A check valve 18 is installed in each case to allow free flow of water to 12.

The check valves 16 and 18 are formed by, for example, relatively thin synthetic resin sheets having a thickness of 2 vans or less, each curved toward the water flow side and screwed to the partition plate 10.

Note that the check valves 16 and 18 can also be formed by tiltably attaching a relatively thin sheet body such as an aluminum plate or a stainless steel plate.

The cover 4 has a front cover part 20 that covers the outdoor surface and a rear cover part 22 that covers the indoor surface, and is a box body that is integrally connected at the corner part by a joint plate 36, and the top and bottom walls and side walls are used for heat storage. The cover 4 can be closely attached to the tank 2, and the length of the cover 4 is approximately 10 mm longer than that of the heat storage tank 2, so that the cover 4 can be moved back and forth.

The cover 4 is formed by cutting out a metal plate or a synthetic resin plate, and the front cover part 20 has an inclined piece 2 that can be brought into close contact with the inclined piece 6.
4 is also formed on the rear cover part 22 with fins 26 into which the fins 8 can be tightly fitted.

Furthermore, in this embodiment, a heat insulating plate 30 fixed to the heat storage tank is attached to the gap between the front cover part 20 and the back cover part 22, and the heat insulating plate 30 is biased by a spring 32 and the front cover part 20 A concave portion 4 formed in the joint plate 36 between the rear cover portion 22 and the
By providing the wedge pieces 34 that are wedge-attached to 0a and 40b, the cover 4 can be in the illustrated state in which the fins 8 and 26 are in contact with each other, and
When the cover 4 moves, the inclined pieces 6 and 24 can be held in each state in close contact with each other, and the fins 24 are attached with gripping pieces 42.

The thickness of the heat insulating board 30 is smaller than the thickness of the cover 4,
The heat storage tank 2 is installed on the floor below the flower box B via the lower heat insulating material 30, and is also connected to the upper heat insulating material 30.
By bringing the flower box B into contact with the lower surface of the shelf board of the flower box B, the flower box B is incorporated under the shelf board.

Note that 42 is a gripping piece.

However, in the device of the present invention, when the cover 4 is moved from the illustrated state by the gripping piece 42 and the inclined pieces 6.24 are brought into close contact with the recessed part 40a and the wedge piece 34, the inclined pieces 6, 24 are moved. The solar heat heats the heat storage liquid R in the heat absorption part 12, and the warmed heat storage liquid R passes through the upper check valve 16 and flows into the heat storage part 14. It passes through the stop valve 18 and flows back to the heat absorption section 12 .

By repeating this circulation, solar heat is stored in the heat storage liquid R in the heat storage section 14.

Furthermore, during heat storage, an air layer is formed within the fins 8 and 26, so that by insulating the rear surface of the heat storage section 14, heat can be stored efficiently.

On the other hand, when dissipating heat, the fins 8 and 2 are
By moving the cover 4 to the illustrated state in which the slanted pieces 6 and 26 are in close contact with each other, the inclined pieces 6 and 26 are separated from each other on the outdoor surface, forming a heat insulating layer consisting of an air layer, thereby preventing heat radiation from the outside to the outdoors. At the same time, the amount of heat stored in the heat storage tank 14 is radiated into the room through the fins 8 and 26 to heat the room.

At that time, the heat storage liquid R in the heat absorption part 12 does not acquire solar heat and is gradually cooled, so that the descending liquid flow closes the check valve 18, while in the heat storage part 14 there is only a convection flow descending on the fin 8 side. This results in efficient heat dissipation.

Further, as in this embodiment, since it is attached to the outer wall W of the building via the heat insulating material 30, heat transfer into the outer wall W can be prevented, and the wedge pieces 34 are used to connect the inclined pieces 6, 24, fins 8, 26.
can be closely attached to improve heat transfer efficiency.

As mentioned above, the device of this invention incorporates a heat storage tank below the flower box, and has a movable cover that can be brought into contact with and separated from the outdoor surface, so it can be installed comfortably and visually, saving space. In addition to making effective use of heat, the cover prevents heat radiation to the outside and provides an efficient heat storage device.

Furthermore, when the heat storage tank is partitioned by a partition plate having check valves on the upper and lower sides, convection can be generated between the heat absorption part and the heat storage part within the heat storage tank, and heat can be collected efficiently.

Furthermore, when air layers can be formed alternately in front and behind the heat storage tank by the cover, heat radiation into the room during heat collection can be prevented and heat storage efficiency can be improved.

Furthermore, by installing inclined pieces and fins, the heat collection area and heat radiation area can be increased.
