First, the greenhouse 100 provides a growth environment (temperature, etc.) in which the object 10 to be warmed can be raised to a proper temperature. In the greenhouse 100, a space 110 having a predetermined width is provided, .

Here, a light incident port 120 may be formed in a lower portion of the greenhouse 100 so that sunlight S is transmitted from a light transmitting portion 200 to be described later.

The light incident port 120 may be horizontally formed at a lower end of one side of the greenhouse 100 and a transparent window (not shown) may be formed in the light incident port 120 so that only sunlight S can pass through the light incident port 120 May be installed.

The light incident port 120 may be formed in a square hole, but the shape of the light incident port 120 may be variously applied.

In addition, since the light incidence hole 120 needs to be opened to the outside, a part of the ground adjacent to the lower end of the greenhouse 100 can be partially excavated to form a path through which the light enters the light incidence hole 120.

In addition, the greenhouse 100 may include a greenhouse capable of raising the object 10 to be heated to an appropriate temperature, but the greenhouse 100 may be made of various structures and materials.

The greenhouse 100 can be used not only as a facility for cultivating and growing the object 10 to be heated at a proper temperature but also as a space where people can dwell.

The light transmitting portion 200 is for reflecting solar light S from the outside of the greenhouse 100 and focusing the sunlight S on the light entrance 110 of the greenhouse 100.

The light transmitting unit 200 may use a heliostat structure that reflects the sunlight S by a parabolic structure or a plurality of reflectors 210 and transmits the sunlight S in a predetermined direction.

The reflector 210 may be separately adjustable in a separate frame, and the shape of the reflector 210 may be variously applied as needed.

1, the optical transmission unit 200 may further include a support 220 for supporting the reflectors 210 at a predetermined height so as to be rotatable and a driving unit 230 for rotating the reflectors 210 have.

That is, the light transmitting unit 200 can concentrate the sunlight S to the entrance of the light incidence aperture 120 even if the sun's position is changed.

Meanwhile, a safety fence (not shown) may be further installed around the light entrance 120 of the greenhouse 100 to prevent the pedestrian from being burned by the sunlight S.

The safety fence may block the gap between the light entrance 120 and the light transmission part 200 so that the pedestrian can not pass the sunlight S incidence section.

In addition, a lamp (LED or the like) 20 may be installed inside the greenhouse 100 for irradiating a light having a wavelength to help the growth of plants, as shown in FIGS.

The blackbody radiation pipe 300 is provided along the bottom surface of the greenhouse 100 for converting sunlight energy into radiant heat and is connected to the sunlight S transmitted to the light inlet 120 of the greenhouse 100, Reflection and absorption.

The blackbody radiation pipe 300 for this purpose may extend from the light incidence hole 120 to have a length along the inner bottom surface of the greenhouse 100.

Here, the blackbody radiation pipe 300 may be installed horizontally at a predetermined height inside a ground layer 600 to be described later.

The black body radiation pipe 300 may include a light reflector or a light scattering structure. The black body radiation pipe 300 reflects and absorbs the sunlight S transmitted through the light incident opening 120 in the longitudinal direction, (600).

A plurality of the blackbody radiation tubes 300 may be formed along the horizontal direction, and the blackbody radiation tubes 300 may be formed in a state in which the one open side is exposed in the light incidence hole 120.

Particularly, the blackbody radiation pipes 300 may be arranged in a plurality of channels. As shown in FIG. 3, the blackbody radiation pipes 300 may be arranged in a sector shape gradually increasing in distance from the light incidence apertures 120.

Here, the blackbody radiation pipe 300 may be made of graphite, wastepaper and graphite-containing polyvinyl chloride (PVC), which can efficiently reflect and absorb the photographed sunlight S, Can be used.

The diffusing member 400 diffuses (convectively radiates) the sunlight S transmitted from the light transmitting unit 200 in a standby state and transfers the sunlight S to the entrance side of the blackbody radiation pipes 300.

The diffusion member 400 may be disposed on the bottom surface of the space 110 so as to be adjacent to the light entrance 120. The diffusion member 400 may reflect the sunlight S to the top surface, A mirror or the like may be used.

Although it is preferable that the diffusion member 400 is installed horizontally so as to be close to the light incidence hole 120, the diffusion member 400 may be inclined at a predetermined angle as required.

Such a diffusion member 300 can radiate solar light in a predetermined direction and efficiently reflect and distribute the sunlight S to the inflow side of the blackbody radiation tube.

The hot water circulation pipe 500 circulates water along the inside thereof and is horizontally arranged with a predetermined length inside the soil layer 600 to be described later as in FIGS. 1 and 2, and heat is transferred from the soil layer 600 to be described later .

Here, the hot water circulation pipe 500 is arranged inside the ground layer 600 to be described later, and horizontally arranged along the upper part of the blackbody radiating pipe 300 to circulate the water.

The hot water circulation pipe 500 can be manufactured using copper or the like, or a polyvinyl chloride (PVC) material containing graphite.

In addition, the hot water circulation pipe 500 can be folded in multiple stages to widen the contact area between the blackbody radiation pipe 300 and a ground layer 600 described later.

The hot water circulation pipe 500 receives the heat of the blackbody radiation pipe 300 and circulates the water supplied from the outside.

A hot water tank 510 to which hot water is supplied may be connected to the hot water circulation pipe 500 and a circulation motor 520 for circulating water may be connected to the hot water tank 510 or the hot water circulation pipe 500 Can be installed.

The hot water tank 510 may be installed inside or outside the greenhouse 100, and water may be supplied from the outside to the hot water tank 510.

Here, the hot water tank 510 has a function of supplying hot water, which moves along the hot water circulation pipe 500, in a predetermined amount for storage and temperature control.

In addition, a temperature controller 530 for sensing the temperature of the greenhouse may be electrically connected to the circulating motor 520.

The temperature regulator 530 senses the internal temperature of the greenhouse 100 using a temperature sensor and can maintain the internal temperature of the greenhouse 100 within a predetermined reference temperature range.

Although the temperature sensor is preferably installed inside the greenhouse 100 as shown in FIGS. 1 and 2, it may be installed in the hot water circulation pipe 500 if necessary.

That is, when the internal temperature of the greenhouse 100 is lowered to a predetermined temperature or less, the circulation motor 520 can be driven to circulate the hot water stored in the hot water tank 510.

For example, the temperature adjusting unit 530 can keep the internal temperature of the greenhouse constant, thereby preventing the temperature of the greenhouse from excessively increasing in the daytime or when the amount of sunshine is large.

On the other hand, when the night temperature or the amount of sunshine is insufficient, the temperature regulator 530 can maintain the temperature of the greenhouse 100 constant by recirculating the hot water stored in the daytime.

The soil layer (soil layer) 600 stores and upwardly discharges the heat of the blackbody radiation pipe 300 to maintain the interior of the greenhouse 100 at a set temperature.

The black body radiation pipe 300 and the hot water circulation pipe 500 may be arranged at a predetermined height in the ground layer 600.

The soil layer 600 may be laminated to a thickness of about 1 to 3 m, but the thickness of the soil layer 600 may be variously applied as needed.

The soil layer 600 may be stacked in a state of filling the space between the hot water circulation pipe 500 and the blackbody radiation pipe 300. The soil layer 600 may have the same height as the ground surface.

The heat-insulating pad 700 is laminated on the soil layer 600 and conveys the heat of the soil layer 600 while preserving the heat.

Here, the thermal pad 700 is made of a fiber material such as a blanket to cover the entire upper surface of the soil layer 600.

That is, since the upper part of the soil layer 600 is blocked by the heat insulating pad 700, the speed at which the heat transferred to the soil layer 600 is propagated to the space 110 of the greenhouse 100 can be controlled, The heat of the heat exchanger 600 can be maintained for a long time.

The mounting table 900 is placed on the upper side of the thermal pad 700 to form a space in which the thermal objects (plants, etc.) 10 can be placed.

That is, even in a low temperature environment such as a winter season, it is possible to provide an environment in which the object 10 to be warmed can be raised to an appropriate temperature without consuming extra fossil energy.

Meanwhile, a heat insulating material 900 may be further provided on the lower portion of the blackbody radiation pipe 300 and the hot water circulation pipe 500.

It is preferable to use a material having a low thermal conductivity (styrofoam, refractory brick, or the like) as the heat insulating material 900.

The heat insulating material 900 may be installed to cover the bottom of the soil layer 600 or the bottom and sides of the soil layer 600.

For example, the edge of the heat insulating material 900 may be extended to cover the edge of the soil layer 600.

As a result, the present invention converts solar energy into radiant heat using the blackbody radiation tube 300, and is used for controlling the internal temperature of the greenhouse 100 and for supplying hot water, thereby being eco-friendly because there is no consumption of fossil fuel.

The internal temperature of the greenhouse 100 is maintained within the reference temperature range by using the hot water circulation pipe 500 and the temperature control unit 530 so that the temperature of the greenhouse 100 excessively increases in the daytime or when the amount of sunshine is large If the nighttime or the amount of sunshine is insufficient, the temperature of the greenhouse 100 can be kept constant by recirculating the hot water stored in the daytime.

While the present invention has been described with respect to specific embodiments thereof with reference to the accompanying drawings, it is to be noted that various changes and modifications may be made without departing from the scope of the present invention.
