Japanese Patent Application No. 61-311485 (Japanese Patent Laid-Open No. 63-165633) Japanese Patent Application No. 62-234666 (Japanese Patent Application Laid-Open No. 64-75858)

  When the outline is demonstrated about FIG. 6, the air flow path 2 which has a roof gradient is formed directly under the metal roof boards 1, such as a color iron plate, as a solar heat collecting part provided in a roof, One end of this air flow path 2 is It opens to the eaves etc. (it may be a back of a hut) as the external air intake 3, and the other end is connected to the ridge duct 4 as a heat collection box by a heat insulating material.

  The lower surface of the air flow path 2 was configured as a heat insulating layer 24 made of a panel board such as glass wool, and a part of the roof was covered with glass 23. The glass 23 prevents the wind from inhibiting the metal roof plate 1 from being heated by solar heat when the external wind is strong.

  A handling box 5 provided with an inflow side damper 6, a heat collecting fan 7 and an outflow side damper 8 is installed in a shed 22 which is an attic space, and one of the outflow side of the outflow side damper 8 is outdoors by an exhaust duct 9. And the other one is connected to the upper end of the falling duct 10. The lower end of the falling duct 10 opens into the air circulation space 13 between the thermal storage soil concrete 11 and the floor panel 12 as a heat storage / radiation part, and a floor outlet 14 from the air circulation space 13 to the room is provided. .

  One of the inflow sides of the inflow side damper 6 of the handling box 5 was communicated with the ridge duct 4 and the other one was connected to a circulation duct 19 opened indoors through a ceiling or the like. If the room provided with the suction port 20 through which the circulation duct 19 is open is on the second floor, the room having the floor panel 12 provided with the floor outlet 14 to the room and the room on the first floor provided with a blow-off structure is air. It is desirable to make the flow freely.

  In the handling box 5, a hot water take-off coil 15 is provided between the inflow side damper 6 and the heat collecting fan 7, and the hot water take-off coil 15 is connected to a hot water storage tank 17 by a circulation pipe 16. A hot water supply boiler 18 for reheating is provided on the way, and a hot water supply pipe 21 connected to a bath, a washroom, and a kitchen is connected.

  In this way, the roof plate 1, which is a metal plate heated by sunlight, warms the outside air entering the air flow path 2, and the warmed air rises along the roof gradient. The heated air is collected in the building duct 4 and then enters the handling box 5 by the heat collecting fan 7 and flows down from the handling box 5 through the falling duct 10 between the thermal storage soil concrete 11 and the floor panel 12. Enter the air circulation space 13. In this air circulation space 13, heated air directly warms under the floor surface via the floor panel 12, stores heat in the thermal storage soil concrete 11, and is blown directly into the room as warm air from the floor outlet 14. The three types of heating are performed.

  On the other hand, the hot water coil 15 heats the water fed from the hot water storage tank 17 through the circulation pipe 16 and stores it as hot water in the hot water storage tank 17. The water is reheated and hot water is supplied from the hot water supply pipes to various places.

  By the way, it is necessary to discharge all the heated air warmed by the roof plate 1 to the outside air and throw it away in the season when the heating is not necessary at a high temperature such as summer. In this case, if the falling duct 10 side which is one of the outflow sides is closed by the outflow side damper 8 and the other side of the exhaust duct 9 which is the other side of the outflow side is opened, the heated air is discharged from the handling box 5 into the exhaust duct 9. It is thrown away outdoors. The heated air passes through the handling box 5 to heat the hot water coil 15, so that it is possible to ensure that hot water can be obtained by using solar heat even at high temperatures such as in summer.

  In addition, the following patent documents show that it is possible to install a heat collection box even when the space in the hut cannot be secured sufficiently or until the hut itself cannot be secured, and the conventional ground plate for each row is penetrated. There is no need to carry out sleeve construction, and construction on the roof is very short.Furthermore, since there are very few places to penetrate the field plate, it is highly reliable in terms of waterproofing. It is easy to inspect and maintain the inside of the duct after completion, and since there is no heat collection box installed on the indoor side of the heat insulating layer of the roof, a solar system house that does not have the risk of heat dissipation into the building is presented. ing.

  As shown in FIG. 7, in the upper area of the roof, the upper part of the roof plate 1 is covered with glass 23 with a vertical interval, and in the lower area of the roof, a solar cell panel ( A PV panel was attached.

  The handling box 5 is installed with shelves in the attic space. Although not shown in the drawing, the inflow side damper, the heat collecting fan, and the outflow side damper are provided in the interior as in FIG. A hot water collecting coil is provided, one of the outflow side of the outflow damper is opened to the outside by an exhaust duct, and the other is connected to the upper end of the falling duct 10. Moreover, the lower end of the falling duct 10 opened to the air circulation space between the thermal storage soil concrete as a heat storage / radiation part and the floor panel, and provided a floor outlet from the air circulation space to the room.

  The heat collection duct box 30 interposed between the air flow path 2 and the handling box 5 is configured as a heat collection duct having an air inlet 31 formed on the side, and is installed on the roof at the upper end position of the air flow path 2. did.

  The handling box connecting sleeve 37 and the handling box 5 are connected by a flexible duct 41 with heat insulation.

  In this way, the roof plate 1, which is a metal plate heated by sunlight, warms the outside air that has entered the air flow path 2, and the heated air rises along the roof gradient, and the heated air is collected. After being collected in the heat duct box 30, it enters the handling box 5.

  As described above, the handling box 5 is installed in the attic which is an attic space, and the hot air passing through the handling box 5 is exhausted to the outside through the exhaust duct passing through the attic.

  Such exhaust is frequently performed in many seasons where heating such as summer is not necessary, but in summer the heat collection temperature is high, and depending on the position where the exhaust duct opens, it fills around the exhaust or depending on the wind direction There is a risk that sufficient exhaust cannot be performed.

  If the exhaust air is insufficient, when the collected high-temperature air passes, the indoor handling box 5 and the exhaust duct become hot, and the indoor temperature rises.

  An object of the present invention is to provide a solar system house that eliminates the inconveniences of the above-described conventional example, enables omnidirectional ventilation without being affected by the wind direction and the like, and enables efficient exhaust.

In order to achieve the above object, the present invention according to claim 1 forms an air flow path having a gradient similar to that of the roof directly below the roof plate, and the lower end of the air flow path opens as an air intake port. A heat collection duct box is connected to the upper end of the air flow path and installed on the roof, and this exhaust duct box is placed on the roof side by side with the heat collection duct box across the ridge. The space between the duct boxes is an exhaust space where the exhaust port on the side of the exhaust duct box opens, and the exhaust space is covered with a ridge ventilation hardware so as to straddle the heat collection duct box and the exhaust duct box. The gist is that it is connected to an exhaust duct or communicated indoors.

  According to the first aspect of the present invention, since the heat collecting duct box and the exhaust duct box are first installed on the roof, they can be installed even when the space of the shed cannot be secured sufficiently or when the shed itself is not present. There is no risk of heat dissipation into the building. In addition, the heat collection duct box can be directly communicated with the air flow path directly below the metal roofing board through the air inlet formed in the side, so that it passes through the field plate of each row between the rafters as is conventionally done. It is not necessary to carry out sleeve construction, and construction on the roof can be completed in a short time. In addition, since there are very few ducts penetrating the base plate in relation to the handling box, the waterproof reliability is high.

  Furthermore, by providing an exhaust duct box, exhaust can be collected and sent out here, and the exhaust from the exhaust duct box is performed from the exhaust space between the heat collection duct box and the exhaust duct box extending over the building. The omnidirectional ventilation is possible.

  Moreover, since the exhaust duct box is installed on the roof side by side with the heat collection duct box, if these are located on the left and right sides of the roof, the balance is very good.

  On the other hand, when the exhaust duct box is used and connected to the indoor exhaust duct, the exhaust from the handling box can be performed through the indoor exhaust duct.

  On the other hand, if the exhaust duct box is communicated indoors without being connected to the handling box via the indoor exhaust duct, it can be used for indoor natural ventilation, and it has a structure such as a blow-off. It is effective.

In addition, by providing building ventilation hardware, the part made up of these heat collection duct box, exhaust duct box and building ventilation hardware protrudes on the roof as a small roof, and a shape like a waist roof in Japanese architecture is obtained. Balance is good.

  Moreover, by covering the exhaust space between the heat collection duct box and the exhaust duct box with the building ventilation hardware, this building ventilation hardware is heated by solar heat and can induce exhaust (passive ventilation).

  According to the second aspect of the present invention, the roof on the side where the exhaust duct is installed also forms an air flow path having a gradient similar to that of the roof directly below the roof plate, and the lower end of the air flow path opens as an air intake. The gist is to allow the upper end of the air flow path to communicate with the exhaust duct box.

  According to the second aspect of the present invention, the roof on the side where the exhaust duct box is installed also collects heat in the same manner as the roof on the side of the heat collection duct box, but the heated air collected here remains as it is in the exhaust duct box. When this is exhausted from the exhaust duct box, it is possible to induce the feeding from the indoor exhaust duct to the exhaust duct box.

  As described above, the solar system house of the present invention can perform omnidirectional ventilation without being affected by the wind direction or the like with respect to exhaust, and can perform efficient exhaust.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a longitudinal front view showing an embodiment of a solar system house according to the present invention, FIG. 2 is a plan view of the same, FIG. 3 is an overall explanatory view, and the same components as those in FIGS. Are given the same reference symbols.

  As solar heat collection provided on the roof, an air flow path 2 having a roof gradient is formed directly below a metal roof board 1 such as a color iron plate (color galva steel plate), and one end of the air flow path 2 is an eaves or the like (a hut) It opens as the outside air intake 3 in the back). The lower surface of the air channel 2 is configured as a heat insulating layer. In addition, the case where the roof board 1 is not made of metal is also conceivable.

  In the upper area of the roof, the upper part of the roof plate 1 was covered with the glass 23 with a vertical interval.

  In FIG. 3, reference numeral 5 denotes a handling box, which is installed in an attic space, and although not shown, an inflow side damper, a heat collecting fan and an outflow side damper are provided in the same manner as in FIG. A hot water take-off coil is provided between the fan and one of the outflow sides of the outflow damper is opened to the outside by an exhaust duct, and the other is connected to the upper end of the falling duct 10.

  Moreover, the lower end of the falling duct 10 opened to the air circulation space between the thermal storage soil concrete as a heat storage / radiation part and the floor panel, and provided a floor outlet from the air circulation space to the room. The handling box 5 may be provided indoors other than the attic space.

  In the present invention, the heat collection box interposed between the air flow path 2 and the handling box 5 is configured as a heat collection duct box 30 in which an air inlet 31 is formed on a side portion so as to communicate with the air flow path 2. This was installed on the roof at the upper end position of the air flow path 2.

  The heat collection duct box 30 is a box made of a composite of a phenol foam heat insulating material, which is a heat insulating material of foamed resin, and a galvalume steel plate, and has a handling box connecting sleeve 36 protruding downward.

  Moreover, the upper surface of the heat collection box 30 was formed as a flat sheet with a waterproof sheet, a plywood plate, and a galvalume steel plate, as constituting the roof.

  The handling box connecting sleeve 36 and the handling box 5 are connected by an intake duct 25 which is a flexible duct with heat insulation.

  Similarly, an air flow path 2 having a roof slope is formed immediately below a metal roof plate 1 such as a color iron plate (color galva steel plate) on the roof opposite to the roof on which the heat collecting box 30 is installed. One end of the path 2 opens as an outside air intake 3 at the eaves or the like (in some cases, behind the hut).

  Further, the exhaust duct box 26 was installed on the roof side by side with the heat collection duct box 30 across the ridge of the ridge beam 37. The exhaust duct box 26 is formed with an intake port 31 at a side portion so as to communicate with the air flow path 2. The exhaust duct box 26 is also a box made of a composite of a phenol foam heat insulating material, which is a heat insulating material of foamed resin, and a galvalume steel plate, like the heat collecting duct box 30, and is as large as the heat collecting duct box 30. That's it.

  In this way, the heat collection duct box 30 and the exhaust duct box 26 are arranged across the building, and an exhaust space 28 in which the exhaust port 27 on the side of the exhaust duct box 26 opens is formed between these.

  Similarly to the heat collection duct box 30, the exhaust duct box 26 has a handling box connection sleeve 36 protruding downward, and is connected to the handling box 5 through an indoor exhaust duct 29.

  The exhaust space 28 is covered with a ridge ventilation hardware 32 so as to straddle the heat collection duct box 30 and the exhaust duct box 26. Thereby, it becomes a so-called waist roof shape in which a small roof protrudes as a whole.

  The building ventilation hardware 32 is supported by a building ventilation hardware base 33 and a ventilation hardware joint hardware 35 above it, and the building ventilation hardware base 33 is fixed to the heat collecting duct box 30 and the exhaust duct box 26 at a field fixing angle 34. The ventilating hardware joint hardware 35 is a coupling hardware that is bridged between the ridge ventilation hardware gantry 33 and supports the ridge ventilation hardware 32 thereon.

  The ridge ventilation hardware 32 is combined with the ridge ventilation hardware gantry 33 so as to prevent the rain from entering the interior, a roof vent (ventilation) structure is formed so that a flow of air that turns is generated.

  In this way, the roof plate 1, which is a metal plate heated by sunlight, warms the outside air that has entered the air flow path 2, and the heated air rises along the roof gradient, and the heated air is collected. After being collected in the heat duct box 30, it enters the handling box 5 through the intake duct 25.

  It flows down in the falling duct 10 from the handling box 5 and enters the air circulation space 13 between the thermal storage soil concrete and the floor panel. In this air circulation space 13, heating air directly warms under the floor via the floor panel 12, stores heat in the thermal storage soil concrete, and blows out directly into the room as warm air from the floor outlet. Performs street heating.

  On the other hand, the water fed from the hot water storage tank 17 through the circulation pipe 16 is heated by the hot water coil 15 and stored as hot water in the hot water storage tank 17, and further hot water is supplied from here through the hot water supply pipes to various places.

  In the high temperature season such as summer, when heating is not necessary, it is necessary to discharge all the heated air heated by the roof plate 1 to the outside air and throw it away. In this case, if the falling duct 10 side which is one of the outflow sides is closed with an outflow side damper (not shown) in the handling box 5 and the other exhaust duct 9 side which is the other outflow side is opened, handling is performed. The heated air from the box 5 is stored in the exhaust duct box 26 through the indoor exhaust duct 29, and enters the exhaust space 28 where the exhaust port 27 on the side of the exhaust duct box 26 opens, and from the building ventilation hardware 32 to the outside. Thrown away.

  In this case, the roof on the side where the exhaust duct box 26 is installed also collects heat in the same manner as the roof on the heat collection duct box 30 side, but the heated air collected here is sent directly to the exhaust duct box 26, This is exhausted from the exhaust duct box 26, so that the indoor exhaust duct 29 is fed into the exhaust duct box 26.

  The heated air passes through the handling box 5 to heat the hot water coil 15, so that it is possible to ensure that hot water can be obtained by using solar heat even at high temperatures such as in summer.

  Further, the heat collecting fan 7 in the handling box 5 is operated at night in summer, and the cold air at night is taken into the air flow path 2 directly below the metal roof plate 1 to cause radiative cooling from the roof surface. Can be sent to the air circulation space 13 between the underfloor heat storage body and the floor panel through the falling duct 10 to cool the soil concrete as the underfloor heat storage body.

  Furthermore, the flow path switching damper in the handling box 5 can be switched to send the air under the floor or indoors from the handling box 5 to the outside through the exhaust duct 9, so that the sultry indoor air can be exhausted in summer or the like.

  The heated air passes through the handling box 5 to heat the hot water coil 15, so that it is possible to ensure that hot water can be obtained by using solar heat even at high temperatures such as in summer.

  4 and 5 show another embodiment of the present invention. In the case where the present invention is used for natural ventilation, the exhaust duct box 26 is not connected to the indoor exhaust duct 29 but provided with a ventilation port 38. Communicated with the room.

  On the roof on the side where the exhaust duct box 26 is installed, the roof plate 1, which is a metal plate heated by sunlight, warms the outside air entering the air flow path 2, and this warmed air rises along the roof gradient. The heated air that has been collected is sent to the exhaust duct box 26 as it is, and is exhausted from the exhaust duct box 26, whereby induced exhaust is performed through the ventilation port 38.

  The building ventilation hardware 32 is heated by the sun, and ascending air is raised, so that passive ventilation by induced exhaust is also possible here.
