５００500 mm). A heat insulating material 12 such as foamed urethane (for example, having a thickness of 25 to 30 mm) is laid on the cobblestone layer 4 so that the geothermal heat stored in the cobblestone layer 4 can easily escape to the outside. Not to be.

On the lower surface of the cobblestone layer 4, for example, a moisture-proof sheet 71 made of vinyl is provided. The moisture-proof sheet 71 prevents the moisture in the ground from rising into the cobblestone layer 4, but allows the moisture in the cobblestone layer 4 to fall into the ground. That is, since the moisture-proof sheet 71 is arranged so that a plurality of sheets are folded on each other, an increase in moisture from below is prevented, but moisture from above overlaps the plurality of sheets. It can be moved downward from the gap between the parts. In FIG. 1, reference numeral 5 denotes an inner wall airflow passage for supplying the air in the attic to the cobblestone layer 4 while passing through the space in the inner wall between the rooms. Note that the inner wall air flow passage 5 is formed in a bellows shape having a large surface area in order to enhance heat conduction efficiency.

In FIG. 1, reference numeral 6 denotes a fan provided on the attic, and reference numeral 7 denotes a fan provided at an intermediate portion of the attic air flow passage 1, and is provided between the fan 6 and an exhaust port 8 communicating with the outside. It is a damper. Reference numeral 9 denotes a damper provided at an intermediate portion of the inner wall airflow passage 5 and interposed between the fan 6 and the cobblestone layer 4. The damper 7 is

It is designed to be closed so as not to escape outside. The damper 9 is closed by a predetermined temperature sensor and a control device so that the humid air of the attic is not heated in the summer through the inner wall air flow passage 5 in the summer, and the warm air of the attic is closed in the winter. Is opened so as to be supplied to the cobblestone layer 4 while warming the room via the inner wall air flow passage 5. Also, in the figure, 10 and 1
Reference numeral 1 denotes an indoor ventilation port for letting room air escape to the attic, and also a passage for natural and jet-generated heat which is also a heat source in winter.

In this embodiment, an underground pipe (outer pipe) 13 extending from the underfloor airflow passage 2 under the floor to the ground via the gangue layer 4 is provided.
FIG. 2 is an enlarged view of the underground pipe 13. As shown in FIG. 2, the lower end of the underground pipe 13 is approximately 2 to 3
m (preferably 2.5 m). The underground pipe 13 has a diameter of, for example, about 300 mm. Also,
The underground pipe 13 is made of metal (for example, iron), and is subjected to a rust prevention treatment by galvanizing the periphery. The lower end of the underground pipe 13 is closed so that groundwater or the like does not enter the pipe 13.

As shown in FIG. 2, a plurality of openings (holes) 13a are formed in a portion of the underground pipe 13 which is in contact with the gangue layer 4. The opening 13 a allows the air in the cobblestone layer 4 to be sent into the underground pipe 13. As shown in FIG. 2, a diameter of the underground pipe 13 is, for example, 200 mm.
A metal inner pipe is inserted. The inner pipe 14 is formed so that its lower end is open and its upper end reaches the underfloor airflow passage 2 above the cobblestone layer 4. Thus, in the present embodiment,
Since the underground pipe (outer pipe) 13 and the inner pipe 14 form a “double pipe structure”, the air in the cobblestone layer 4 first passes through the opening 13 a through the underground pipe 13. And enters the passage 15 between the inside pipe 14 and slowly descends in the passage 15. Thereafter, when the air reaches the bottom 13 b of the underground pipe 13, the air makes a U-turn at the bottom 13 b and rises inside the inner pipe 14, and is sent to the underfloor air flow passage 2 from above the inner pipe 14. . In the present embodiment, while the air from the cobblestone layer 4 descends along the passage 15, geothermal heat of about 2.5 to 3 m underground is transmitted to the air via the underground pipe 14. Will be.

FIG. 3A is a perspective view showing the underground pipe 13 partially seen through, and FIG. 3B is a sectional view of the underground pipe 13. As shown in FIGS. 3A and 3B, the underground pipe 13 is provided with a large number of metal fins 16 inside the underground pipe 13 (FIG.
The illustration of the fin is partially omitted). The plurality of fins 16 are provided, for example, inside the underground pipe 13 so as to be scattered, for example, in a spiral shape (spiral shape). FIG. 3C is a perspective view showing the inner pipe 14, and FIG. 3D is a view showing the underground pipe 13 and the inner pipe 14.
It is sectional drawing which shows the "double pipe structure." This figure 3
As shown in (d), a large number of fins 16 are scattered in the passage 15 between the underground pipe 13 and the inner pipe 14.

As described above, in this embodiment, since a large number of metal fins 16 are provided inside the metal underground pipe 13, geothermal heat of 2.5 to 3 m underground is generated by the underground pipe 13. 13 to a large number of fins 16. Therefore, in the present embodiment, while the air in the cobblestone layer 4 enters the underground pipe 13 and descends the passage 15, the air contacts and collides with the many fins 16. (As a result, the air is swirling or swirling) and slowly descends. In the process, geothermal heat is efficiently transmitted from the fins 16 and the underground pipe 13 to the air. That is, in the present embodiment, since the geothermal heat is transmitted from the underground pipe 13 and the fins 16 to the air, a cooling action for cooling the air is obtained in summer and a heating action for warming the air in winter is obtained. (The underground pipe 1
3 and the fins 16 "air conditioning effect").

In the present embodiment, when a large amount of outdoor humid air is sent into the underground pipe 13 in summer, the large number of fins 16 also exert an action of dehumidifying the air. It has become. That is, in summer,
The fins 16 are kept at a relatively lower temperature than outdoors by geothermal heat. When high-temperature and high-humidity air from outside collides with these low-temperature fins 16, dew condensation occurs, and moisture contained in the air adheres to the surface of the fins 16, and as a result, the air is dehumidified. become. On the other hand, in the present embodiment, when the air dried in winter is sent into the underground pipe 13, the large number of fins 16 also have an effect of supplying moisture to the air. . That is, in winter, the fins 16 are kept at a relatively higher temperature than the outdoors or the whole building by geothermal heat.
When the dry air collides with these high-temperature fins 16, the moisture previously attached to the surface of the fins 16 is supplied to the air, and as a result, the air contains some moisture. Thus, in the present embodiment, the large number of fins 16 exhibit an effect of adjusting the humidity of the air in the underground pipe 13 (constituting the “air humidity adjusting means” in the present invention). I have. In the present embodiment,
The underground pipe 13 itself also exerts to some extent substantially the same effect as the air humidity control of the fins 16.

Further, in the present embodiment, the large number of fins 16 also have a function of purifying the air sent into the underground pipe 13. That is, a certain amount of moisture usually adheres to the surfaces of the large number of fins 16 due to condensation or the like. In this state, dirty air from the outside enters the underground pipe 13 and the passage 1
As the air descends slowly in the space 5, the air hits many fins 16. In general, moisture has a property of attaching minute impurities that cause dirt such as dust and dirt in the air. Therefore, in the process in which the dirty air enters the underground pipe 13 and moves in the passage 15, the components of the dirt (fine impurities) in the air become the moisture on the surface of the fin 16. Be attached to. As a result, the air is cleaned.

As described above, in the present embodiment, the fins 16 have the function of purifying the air moving through the passage 15 to some extent (constituting the "air cleaning means" of the present invention). ing. The relatively large impurities in the air that have not adhered to the fins 16 are:
When the air rises from the bottom 13b of the underground pipe 13, the air will not rise due to its own weight but will accumulate in the bottom 13b. At this point, the air is also cleaned to some extent.

In this embodiment, as shown in FIG. 2, a basket receiver 17 is provided at an intermediate portion of the inner pipe 14. On this basket receiver 17, there is placed an air-permeable basket 18 containing materials that generate and emit fragrance such as herbs. Therefore, the air rising from below the inner pipe 14 passes through the basket 18 so that a predetermined good scent is given, and the air having the pleasant scent is sent to the underfloor air flow passage 2. It has become. In the present embodiment, the basket 18 containing the herbs may be provided at the upper end of the inner pipe 14 (a portion surrounded by a broken line indicated by an arrow A in FIG. 2). By doing so, the cage 18 can be arranged closer to the room, so that the fragrance can be more efficiently applied to the air supplied into the room, and the floor inspection and ventilation port 2 can be provided.
It is convenient because the herbs in the basket 18 can be exchanged and groomed by reaching from zero.

As shown in FIG. 2, in this embodiment, an inspection port and a ventilation port 20 are formed in a portion of the floor 30 facing the inner pipe 14. The inspection port 20 is normally used to allow a part of the air supplied from the inner pipe 14 to the underfloor air flow passage 2 to flow into the room. In addition, the inspection port / ventilation port 20 is provided with water accumulated on the bottom 13b of the underground pipe 13 once or several times a year (water condensed on the surface of the fin 16 falls and accumulates on the bottom 13b). Is sometimes used as an inspection port of the underground pipe 13 and the inner pipe 14 for performing the removal work and the like. Also,
This inspection port / vent 20 is a basket 1 containing the herb.
8 is also used for maintenance.

FIG. 4 shows an example of the installation positions of the underground pipe 13 and the inner pipe 14. As shown in FIG. In the example shown in FIG. 4, the pipes 13 and 14 are buried at approximately the center of each of the four rooms on the first floor of a building (in this case, a house).

In this embodiment, the cobblestone layer 4
Is formed by filling a large number of cobblestones in the space below the underfloor airflow passage 2 and surrounded by the foundation concrete (the rising portion of the foundation). Also,
In the present embodiment, charcoal is inserted between the numerous cobblestones. In addition, the cobblestone layer 4 is provided with an intake port 21 for allowing air from outside in the summer to flow into the cobblestone layer 4. This intake port 21 is desirably provided on the north side of the building (in the summer, it is better to take in air from the north side instead of the south side where the sunlight is directly applied, and the underground with the cobblestone layer 4 and the fins 16) The cooling efficiency of the air by the pipe 13 is increased). The intake port 21 is open in summer and closed in winter.
The opening / closing operation of the intake port 21 is automatically opened / closed by a temperature sensor (a setting is made in advance such that the user opens the door when the outside air temperature exceeds a predetermined temperature, and closes the door when the outdoor temperature falls below the predetermined temperature, etc.). ), Or may be opened and closed by a user operating a switch on the control panel.

In this embodiment, the intake port 21
Alternatively, a removable cassette containing activated carbon with a filter may be provided. The cassette containing activated carbon is detachably attached to the intake port 21 and can be detached therefrom. For example, a granular container is filled with granular activated carbon. By using the cassette containing activated carbon, the air from the outdoors enters the karate layer 4 after being subjected to humidity control, deodorization and purification to some extent by the cassette, so that the air supplied to the room can be controlled and dehumidified. The odor and cleaning are more effectively performed.

In the present embodiment, in the summer, hot and humid air from outside flows into the cobblestone layer 4. At this time,
The high-temperature and high-humidity air that has flowed in comes in contact with a large number of gems cooled from the outdoors by geothermal heat and is cooled to some extent (cooling action), and the moisture in the air is condensed on the surface of the gems and dehumidified to some extent. (Dehumidifying action). In addition, the high-temperature and high-humidity air from the outside comes into contact with the charcoal and is dehumidified (humidifying action of the charcoal), and at the same time, dirt and odor components in the air are adsorbed to the charcoal (charcoal Adsorption / purification action). Further, in winter, when dry air in winter passes, the charcoal supplies its own moisture to the air, so that a certain amount of moisture is given to the air (humidifying action of the charcoal) and the charcoal is Since the odorous components in the air are adsorbed, the air is purified (the action of purifying charcoal).

As described above, in this embodiment, the temperature of the air passing through the cobblestone layer 4 is adjusted by the cobblestone (conducting geothermal heat) and charcoal in the cobblestone layer 4. Together with (by heat exchange with geothermal heat), the cobblestone and charcoal in the cobblestone layer 4 perform the humidity control and purification of the air (that is, the cobblestone layer 4,
Together with the underground pipe 13 and the fins 16, the "air conditioning means" and "air cleaning means" of the present invention are also configured).

Next, the operation of this embodiment will be described. First, the operation of the present embodiment in summer will be described. In the summer, the temperature of the air in the attic (attic) rises due to solar heat or convection and becomes, for example, 25 ° C. or more, by the operation of a temperature sensor and a control device (microcomputer) including a thermostat (not shown) and the like. Then, the ventilation motor (motor for fan 6) starts to rotate automatically,
Is open for summer, and the hot air behind the ceiling is discharged outside (while the damper 9 is closed). Therefore, the cobblestone layer 4
The inside and the inside of the two-layer pipe (the underground pipe 13 and the inside pipe 14) have a negative pressure, and the outside air outside is taken in from the intake port 21 of the northern base part. The sucked air passes through a cold storage heat tank (grindstone layer 4), and is passed through a two-layer pipe 13,
14, while being cooled (and while being humidified and purified), it flows into the room or the like from the underfloor air flow passage 2. The air that has flowed into the room moves from the room ventilation opening 10 to the attic, and pushes up hot air in the attic (indoor ceiling). The air containing the hot air is discharged outside through the attic air flow passage 1 by the power of the motor of the fan 6. The above operation is repeated during the daytime in summer (25 ° C. or higher), and all the houses are cooled by geothermal energy. On the other hand,
At night, when the temperature in the attic falls below 25 ° C, the thermostat automatically activates and the fan motor stops. This completely eliminates sleepiness in summer. The temperature set value of the thermostat can be easily changed by the user according to his / her preference (whether it is a hot type or a cold type) by a dial type switch provided on the control panel.

That is, in FIG. 1, arrows indicate the flow of air in a building provided with the present embodiment in summer. In the summer, as shown in FIG. 1, the fan 6 is operated and hot air in the attic is discharged outside through the damper 7 and the exhaust port 8. As a result, the inside of the building has a negative pressure, so that the outdoor air flows into the cobblestone layer 4 from the opened intake port 21. This air is subjected to cooling in the cobblestone layer 4 by heat exchange with accumulated geothermal heat, and dehumidification and purification by contact with the cobblestone and charcoal. After that, the air cooled, humidified and purified by the cobblestone layer 4 enters the underground pipe 13 through the opening 13a of the underground pipe 13 (see FIG. Of the geothermal temperature (underground 2.
5 m of geothermal heat is maintained at about 18 to 19 ° C. as shown in FIG. 5). Cooling is performed by heat exchange between the underground pipe 13 and a large number of fins 16 which are maintained. . At the same time, the air (high-temperature, high-humidity air) comes into contact with the fins 16 maintained at the above-mentioned geothermal temperature, thereby causing dew condensation on the surface of the fins 16 and dehumidifying. At the same time, the air is cleaned by contacting the moisture on the surface of the fins 16 and the impurities in the air are adsorbed by the moisture. Then, the cooled, dehumidified and purified air rises in the inner pipe 14, and passes through a basket 18 containing herbs provided in the middle thereof, whereby the aroma of the herbs is attached. The air provided with the scent enters the underfloor air flow passage 2 from above the inner pipe 14, and a part of the air flows into the room from the inspection port and the ventilation port 20 to cool the room, and to cool the room. Part of the air flows into the outer wall air flow passage 3 to cool the inside of the room from the outer wall.

Next, the operation of this embodiment in winter will be described. In winter, the changeover switches of the dampers 7 and 9 are set for winter or the thermostat temperature is set to about 15 ° C. Thus, when the temperature of the attic reaches 15 ° C. or higher, the motor rotates, and air passes through the warming heat layer (cobblestone layer 4) and the two-layer pipes 13 and 14 under the floor. It circulates through the room, passes through the room ceiling ventilation hole, is sucked in by the power of the fan motor, and is again sent to the cobblestone layer 4. Repeat the above action to warm the whole room. In addition, users can
By keeping the timer for summer twice for about 5 to 10 minutes, it becomes possible to automatically remove the dirty air to the outdoors (this forms an automatic ventilation system).

That is, in FIG. 6, arrows indicate the flow of air in a building provided with the present embodiment in winter. In winter, as shown in FIG. 6, the fan 6 is operated, and the air warmed by the solar heat of the attic and the heat generated by the nature and the jetty flows through the damper 9 and the inner wall air flow passage 5 to form the gangue layer. 4 (note that since the intake port 21 is closed in winter, outdoor air does not flow into the cobblestone layer 4). This air, in the cobblestone layer 4,
It is heated to some extent, humidified (humidified), and purified by contact with quarry stone and charcoal. Thereafter, the air warmed, conditioned and purified by the cobblestone layer 4 enters the underground pipe 13 through the opening 13a of the underground pipe 13 (see FIG. Slowly descends the passage 15. In this process, the air is maintained at the geothermal temperature (the geothermal heat of 2.5 m underground in winter is maintained at about 17 to 15 ° C. as shown in FIG. 5). The temperature is adjusted (heated) by heat exchange with a large number of fins 16. At the same time,
The air comes into contact with the large number of fins 16 (having moisture attached to the surface). At this time, due to the contact with the moisture on the surface of the fins 16, the moisture of the fins 16 is supplied to the air, and Humidity control (humidification) is performed. At the same time,
The air comes in contact with the fins 16 (having moisture attached to the surface), and impurities in the air are adsorbed by the moisture of the fins 16, whereby the air is cleaned.

Embodiment 2 FIG. Next, FIG. 7 is a diagram for explaining Embodiment 2 of the present invention. In the second embodiment,
Instead of using a metal pipe such as an iron pipe as in the first embodiment, a “double pipe” buried in the ground from the quarry layer 4 uses a plastic spiral pipe such as polyethylene or polyester. It is composed. The portions other than the structure of the “double pipe” are substantially common to the second embodiment and the first embodiment, and therefore, the following description will focus on the structure of the “double pipe”.

FIG. 7A is an exploded perspective view of a double pipe used in the second embodiment. In FIG. 7A,
Reference numeral 51 denotes an outer spiral tube made of, for example, polyethylene or polyester having a diameter of 300 mm. As shown in FIG. 7B, the outer spiral tube 51 is formed of a thin sheet having a corrugated cross section (having irregularities formed in a spiral shape), and therefore has a larger surface area than a normal tube. Extremely large. Further, since the outer spiral tube 51 is made of plastic, its thickness is very thin, for example, about 2 to 4 mm as compared with a metal tube. Therefore, it is generally said that the thermal conductivity of a plastic tube is lower than that of a metal tube, but the outer spiral tube 51 of the present embodiment has a large surface area and a small thickness as described above. Therefore, geothermal heat can be easily transmitted to the inside of the pipe. Above the outer spiral tube 51, a plurality of openings (holes) 51a for letting the air from the cobblestone layer 4 flow are formed.

In FIG. 7A, reference numeral 52 denotes a spiral band made of metal, for example, aluminum. The spiral band 52 is formed by forming a band (or ribbon) aluminum sheet into a spiral (or coil) shape. This spiral band 52
The outer spiral tube 51 is installed and used inside the outer spiral tube 51 so as to contact (contact) the inner wall portion of the outer spiral tube 51. Therefore, the spiral band 52
The geothermal power from the outer spiral tube 51 is conducted, and is maintained at substantially the same temperature as the geothermal power.

In FIG. 7 (a), reference numeral 53 denotes a plastic inner spiral tube,
2 is installed inside. Like the outer spiral tube 51, the inner spiral tube 53 also has a corrugated cross section, a larger surface area, and a smaller thickness.

As described above, in the second embodiment, the outer spiral tube 51 having good heat conduction efficiency because of its large surface area and small wall thickness, and the metal spiral band portion 52 having good heat conduction efficiency are provided. The inner spiral tube 53 having a large surface area and a small thickness and having good heat conduction efficiency constitutes a "double pipe".

In the “double pipe” of the second embodiment, the air from the spar layer flowing into the outer spiral pipe 51 is supplied between the outer spiral pipe 51 and the inner spiral pipe 53. The passage (see reference numeral 15 in FIG. 2) slowly descends (contacts with the spiral band portion 52 in the process of descending), and the outer spiral tube 5
When it reaches the bottom of No. 1, it makes a U-turn there and rises inside the inside spiral tube 53, and is supplied to the underfloor air flow passage (see reference numeral 2 in FIG. 1 or FIG. 2). That is,
Also in the second embodiment, the flow of air in the “double pipe” is basically the same as in the first embodiment. Therefore, according to the second embodiment, substantially the same operation and effect as those of the first embodiment can be obtained.

That is, in the second embodiment, the air that has flowed in from the cobblestone layer (see reference numeral 4 in FIG. 1) through the opening 51a is the outer spiral tube 51 maintained at the above-mentioned geothermal temperature. In addition, the temperature is adjusted by contact with the spiral band portion 52 (that is, it is cooled in summer and warmed in winter). At the same time, the air from the cobblestone layer is humidified by contact with the outer spiral tube 51 and the spiral band 52 (that is, in summer, the moisture in the air is reduced by the spiral band). 52 and dew on the surface to dehumidify the air,
In winter, moisture attached to the surface of the spiral band 52 or the like is supplied to the air to humidify the air.) At the same time, the air from the cobblestone layer is cleaned by contact with the outer spiral tube 51 and the spiral band 52 (that is, impurities in the air are removed by the spiral band 52 and the like). Is removed by being adsorbed on the water on the surface of the surface, so that the air is purified).

As described above, the first and second embodiments of the present invention
However, the present invention is not limited to this, and various modifications are possible. For example, in the above two embodiments, as a means for performing temperature control, humidity control, and cleaning of the air underground, a “double pipe structure” such as inserting the inner pipe 14 into the underground pipe 13 is used. However, the present invention is not limited to this,
For example, as shown in FIG.
8 is buried underground, air is flowed in from the end of A in FIG. 8, the temperature of the air is adjusted, the humidity is adjusted, and the air is cleaned inside. The other B may be discharged from the end.

In the present invention, for example, as shown in FIG. 9, the center of a single cylindrical (or columnar) pipe 34 having a large number of fins 33 on the inner wall is divided into two left and right spaces inside the pipe. A partition plate 35 for partitioning the space is provided, and air is allowed to flow from an opening (hole) 36 above the space on the left side of the drawing partitioned by the partition plate 35 (see the arrow C in FIG. 9). The temperature of the air is adjusted, humidified, and cleaned while slowly lowering the air. When the air reaches the bottom, the air is turned U and the inside of the space on the right side of the drawing partitioned by the partition plate 35 is slowly raised. Then, it may be discharged from above (see arrow D in FIG. 9).

FIG. 10 is a diagram showing another example of the "underground pipe" in the present invention. In FIG. 10, 61
It is an outer pipe buried underground from the cobblestone layer (see reference numeral 4 in FIG. 1). The outer pipe 61 is made of plastic, for example, and is formed to be extremely thin so that geothermal heat is easily conducted (the outer pipe 61 may be made of metal). The outer pipe 61 is formed in a large wavy (or irregular) shape as shown in the figure. The upper surface portion (the portion indicated by reference numeral 62 in FIG. 10) of the inner wall of the outer pipe 61 having a corrugated (or uneven) cross section is formed by the portion (surface) indicated by the reference numeral 62 of the air traveling inside the outer pipe 61 downward in the figure. (Contact portion), that is, so as to protrude in a direction orthogonal or oblique to the moving direction of the air so as to hinder the progress of the air. Then, when the descending air comes into contact with the surface contact portion 62, geothermal heat is conducted to the air. In FIG. 10, reference numeral 63 denotes an inner pipe, which is inserted into the outer pipe 61.

That is, in the example of FIG. 10, the air from the cobblestone layer flows into the outer pipe 61 from the opening 61a above the outer pipe 61 (see arrow a in FIG. 10).
It descends (moves) slowly. At this time, descend (move)
The flowing air comes into contact with the wavy (or uneven) surface contact portion 62 (the surface contact portion 62 comes into contact with air so as to prevent the air from traveling). In the process where the descending (moving) air comes into contact with the surface contact portion 62, geothermal heat is transmitted to the air through the thin outer pipe 61. When the air reaches the bottom of the outer pipe 61, the air makes a U-turn there and enters the inner pipe 63 through the lower opening 63 a of the inner pipe 63 (see arrow b in FIG. 10) and rises. Then, the air is supplied from the underfloor air flow passage (see reference numeral 2 in FIG. 1) to each room or the like.

As described above, in the present invention, "a surface contact portion extending in a direction perpendicular to or at an angle to the moving direction of air so as to come into contact with moving air".
Are the fins 16 of FIG. 2, the spiral band of FIG. 7, and FIG.
Various forms are possible, such as the fin 31 of FIG. 9, the fin 35 of FIG. 9, and the upper surface of the inner wall having a corrugated (uneven) cross section of FIG.
