The operation of the present invention as described above is as follows.

As shown in FIG. 1, in the concrete heat storage device according to the present invention, the radiant heat of the sun is collected and collected by the heat storage device 100 while the water is supplied to the water storage tank 10 through the water supply line 12. When the heat exchange pipe 110 installed therein is heated and the water inside is heated, the water is supplied to the heat exchanger 16 according to the operation of the control valve 20 and the circulation pump 30. Since the water is heat exchanged with the water remaining in the water storage tank 10 by the heat exchanger 16, the water remaining in the water storage tank is heated. In this way, the heat-exchanged water in the storage tank 10 is discharged through the hot water supply line 18 to be used for a predetermined purpose.

At this time, looking at the process of collecting the heat of the sun in the heat collecting and heat storage device 100, as shown in Figure 2a and 5, the heat absorbing surface 121 of the heat storage member 120 is the direction in which sunlight is irradiated When it is located at the heat absorbing surface 121 is absorbed radiant heat to the first heat accumulator 122 through the second heat accumulator 124 to heat the heat exchange pipe 110 and thereby the water contained therein Warmed up.

Since the heat source remains and is preserved in the course of passing through the heat storage unit 124, the heat storage operation is performed at the same time.

In addition, the heat absorbing surface 121 is installed in a direction in which sunlight is irradiated as described above, and thus, in the process of collecting and storing heat, the heat accumulating member 120 is in a state of being unfolded toward the sunlight even when sunlight is irradiated to the indoor side. Since the direct inflow of light is first blocked, not only the function of blinding is performed, but also the radiant heat of the sun applied to the heat storage member is insulated by the heat insulating material, so the heat transfer to the indoor space is also blocked and the cooling function is required during the day or summer when cooling is required. It can be improved to save energy.

On the contrary, at a time such as night or winter when heating is required, as shown in FIG. 2A, when the heat absorbing surface 121 is positioned to the indoor side by operating the reversing device 130, The heat source stored in the first heat storage unit 122 and the second heat storage unit 124 is discharged to the indoor space to perform a function as a heating device to warm the indoor air.

The heat storage member to which the first and second hinge pieces 131 and 132 are connected while the operation force is transmitted to the second hinge pin 132 is rotated based on the heat exchange pipe 110, so that the position of the heat absorbing surface 121 is indoor or It can be conveniently used while operating to be located outside.

As described above, the concrete heat storage device according to a preferred embodiment of the present invention is shown in accordance with the above description and drawings, but this is merely described, for example, various changes and modifications within the scope without departing from the technical spirit of the present invention. It will be appreciated by those skilled in the art that this is possible.

According to the concrete heat storage device according to the present invention, since the function of collecting the solar energy and at the same time the heat storage function is performed at the same time, the collected solar energy can be used for a predetermined purpose as well as the heat energy stored on the heat storage member. It can be used directly and conveniently by simple operation, thereby saving energy. And since it can be installed in the position where the solar light is irradiated in a blind form, it can be conveniently used as a sunscreen shielding device. Especially, in the process of blocking sunlight, the heat radiation of the sun is insulated by the heat insulating material, so the heat transfer to the interior space is perfect. Blocking has the effect of further improving the cooling function.
