Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an environmental structure inside a house that also uses geothermal heat, solar heat, and indoor heating intake and exhaust to remove snow on the roof.

Various types of water heating devices have been developed, including conventional roof snow removal mechanisms that utilize geothermal heat and indoor warm exhaust gas, and so-called solar systems that utilize solar heat.

However, these systems are only used for the purpose of removing snow from roofs or for using hot water heated by solar heat for bathing or washing, and especially for snow removal, heaters, etc. are required in addition to geothermal heat. This increases fuel costs, and since the roof is heated from below, the piping structure is complicated, and there are very few examples of it actually being used, and its effectiveness cannot be expected.

The present invention was developed to solve these problems, and uses geothermal heat to slightly warm the air obtained from the basement of the floor, and heats the air by using it in a solar heat absorption box installed on the south wall of the house. The warm air is then guided into the heated room or over the eaves of the roof.In particular, when it comes to roofs, warm air is passed through the entire width of the eaves at the end of the eaves, and the warm air is drawn through small holes in the pipe. This provides an environmental structure that can melt snow from the roof and maintain indoor warmth, with extremely high snow melting efficiency as warm air directly hits the ice and snow to discharge.

The invention will be explained with reference to the accompanying drawings. The drawings show an embodiment of the present invention, in which Fig. 1 is a sectional view showing the mechanical relationship of the invention, Fig. 2 is a plan view showing the roof snow removal structure, and Fig. 3 is a roof snow removal structure. This is an enlarged view of a snow pipe, and Figure 4 shows an enlarged view of a pipe buried underground.

In the figure, 5 is a pipe buried in the foundation of the floor 14 of the house, and it is convenient to bury it at the foundation at the time of construction. It is not difficult to excavate the area under the floor after construction.

This pipe buried underground has 1 pore for water drainage.
2, with a diameter of about 20 cm and a length of 1 m or less, is sufficient.As shown in the enlarged view of Fig. 5, the intake pipe 8 and the air supply pipe 6 are connected back and forth, and the intake pipe 8 is a curved pipe. The air pipe 6 is connected to a solar heat absorption box 2 which will be described later. As described above, this underground pipe 5 has pores 12 for draining water, so when buried, it is preferable to surround it with gravel 13 to prevent the intrusion of earth and sand, and it is constructed of gravel in this way. Possibly pipe 5
A void is created around the pores 12, allowing air to enter through the pores 12. Reference numeral 2 is a solar heat absorption box, which is installed in a suitable sunny place on the wall 1 on the south side of the house, with an air pipe 6 connected to the underground pipe 5 from below, and an air supply pipe 6 leading to the roof 3 from above. Connect the trachea 7. Since this solar heat absorption box 2 simply warms the air sent to it, a simple structure is sufficient as long as it absorbs heat, and it can be constructed from tempered glass such as wired glass and a black iron frame. Appropriate.
The air pipe 7 above the solar heat absorption box 2 protrudes above the eave end and is connected to the center position A of the snow removal pipe 4 provided over the entire width of the eave end on the roof. As shown in the enlarged view of FIG. 4, the snow extinguishing pipe 4 at the end of the eaves is provided with a large number of small holes 11 on the upper surface in the direction of extension, that is, toward the ridge side of the roof, and serves as a hot air outlet. Although this snow-blowing pipe 4 may be installed in a straight line on the roof, it is more effective to remove snow by setting it at an angle R so that it forms a slightly loose V-shape from the center part A to the left and right as shown in the figure. becomes good.

Although this air is heated by solar heat and forcedly blown by a fan (not shown), the temperature of the air reaching this snow-blowing pipe 4 in winter cannot be expected to rise significantly, at most around 10 to 15 degrees Celsius. If the pipe 4 is installed in a straight line, it will be difficult to reach the far end of the pipe, and the snow at both ends of the pipe will tend to be difficult to melt. However, if it is formed into a V-shape with rounded corners, the snow on the roof will slide down and be blocked by the pipe 4, gathering near the center point A as shown by the arrow S, and the relatively high temperature snow will be ejected from near the point A. The warm air with strong jetting force promotes the melting of concentrated snow.

Painting this snow-blowing pipe 4 black is effective in promoting heat absorption, and in this case, the snow-blowing pipe 4 is
There may be cases where installation on the roof is sufficient.

Further, branch pipes 9 and 10 may be provided in the middle of the air supply pipe 7. This branch pipe 9 is an air pipe that sends the air warmed by the solar heat absorption box 2 into the room.If this branch pipe 9 is extended to the room N on the north side as shown by the broken line and the air is released, the north side is always cold during the winter. It is possible to send warm air from room N to raise the temperature inside the room. The branch pipe 10 is an exhaust pipe from the room, and sends hot exhaust heated by the heater K in the room to the pipe 4 on the roof 3 through the air pipe 7.

The structure of the present invention uses warm air from underground, but since the rise in temperature of this underground air is extremely small, in some cases, the construction of an underground trench for this purpose may be omitted, and it may be possible to simply It is also possible to warm the air by the solar heat absorption box 2 and achieve the purpose of snow removal from the roof and room heating by this alone.

That is, as shown in FIG. 5, a solar heat absorption box 2 with an open bottom 2' type is used, and this is installed on the wall 1 on the south side of the house, from which an air pipe 7 is directed upward and guided onto the roof, and a snow removal pipe 4 is installed. The same purpose can be achieved by connecting the air pipe 7 to the air pipe 7. In this case, if a control valve 15 is provided in the middle of the air pipe 7, roof snow removal and room heating can be used alternately.

In addition, in the case of only the solar heat absorbing box 2, the purpose of heating the building can be achieved by providing it on the wall surface 1' of the building over all floors as shown in FIG.

Since the indoor environment structure of the present invention that also serves as a roof snow remover has the above-mentioned configuration, its function is as follows: Although not shown in the drawings, by installing fans at appropriate locations and suctioning the inside of the air supply pipes 6 and 7, the air under the floor and The underground air is heated by geothermal heat in the buried pipe 5 and sent to the solar heat absorption box 2 as shown in a. Inside this solar heat absorption box, even in winter, the air is in a sunny place on the south side, so the air is heated and warm air d is ejected from the small holes 11 of the snow-blowing pipe 4 on the roof 3, promoting snow melting. In addition, the warm air b is introduced into the room from the branch pipe 9 of the air pipe 7, warming the room, and if this branch pipe 9 is extended to reach the room N on the north side, the room on the north side is always warmed. It can be heated. Furthermore, from the branch pipe 10, the warm exhaust gas c that has been heated inside the room is guided onto the roof. Because of this structure, the indoor warm exhaust c can be controlled so that if a large amount of snow falls during the night, the heater K is activated during the night to send the warm exhaust c to the roof. It is possible to melt snow on the same day, there is no burden of snow removal, and there is no need for fuel costs. Snow on the roof can be melted using geothermal heat, solar heat, and indoor exhaust.
In addition, warm air can also be sent to rooms on the north side, so it has a much more effective effect than conventional snow-melting structures of this type.
