[0002]

2. Description of the Related Art It has long been practiced to open a large opening on the south side of a house to receive a large amount of winter solar radiation and to open a part of it in summer for ventilation. Taking this one step further, a sunroom is created outside the living room, and this is used as a greenhouse to take warm air from here into the living room. The applicant has previously proposed and applied for a solar system house that promotes this reasonably and can effectively use air collected by sunlight without being limited to the direction. Japanese Patent Application No. 61-311485 (Japanese Patent Application Laid-Open No. 63-165633) and Japanese Patent Application No. 62-234666 (Japanese Patent Application Laid-Open No. 64-75858) are such.

Referring to FIG. 2, an air flow passage 2 having a roof slope is formed directly under a roof plate 1 such as a color iron plate, and one end of the air flow passage 2 is opened at the eaves as an outside air intake 3. The other end is communicated with the ridge duct 4 as a heat collecting box made of a heat insulating material.

A backflow prevention damper 6, a fan 7, and a flow path switching damper 8 are provided therein.
One of the outflow sides is provided with a handling box 5 which is opened to the outside by an exhaust duct 9 in the attic space, which is an attic space, and the inflow side of the backflow prevention damper of the handling box 5 communicates with the ridge duct 4. One of the outflow sides of the road switching damper 8 is connected to the upper end of the falling duct 10. The lower end of the falling duct 10 is open to an air circulation space 13 between the heat storage soil concrete 11 and the floor panel 12, and a floor outlet 14 from the air circulation space 13 to the room is provided.

[0005] As described above, the inflow side of the backflow prevention damper 6 of the handling box 5 is connected to the ridge duct 4, and the inflow side of the backflow prevention damper 6 is connected to the circulation duct 19 which is open to the room on the ceiling or the like. The backflow prevention damper 6 is configured as a flow path switching damper for switching the flow path between the ridge duct 4 side and the circulation duct 19 side.
Further, if the room provided with the suction port 20 in which the circulation duct 19 is opened is the second floor, if the room on the first floor where the floor panel 12 provided with the floor outlet 14 to the room is provided has a blow-through structure, Is desired to flow freely.

In the handling box 5, a hot water removing coil 15 is provided between the backflow prevention damper 6 and the fan 7,
The hot water coil 15 is connected to a hot water storage tank 17 by a circulation pipe 16, and a hot water supply boiler 18 for additional heating is provided in the hot water storage tank 17, and a hot water supply pipe 21 connected to a bath, a washroom, and a kitchen is provided.
Connect.

[0007] In this manner, the roof plate 1, which is a metal plate heated by sunlight, warms the outside air entering the air flow path 2,
This warmed air rises along the roof slope. Then, the heated air is collected in the ridge duct 4 and then enters the handling box 5 by the fan 7, flows down from the handling box 5 into the falling duct 10, and circulates air between the heat storage soil concrete 11 and the floor panel 12. Enter space 13. In this air circulation space 13, the heated air directly warms the floor below the floor via the floor panel 12, and the heat storage soil concrete 11
In this case, three types of heating action are performed: storing heat in the room and blowing the warm air directly from the floor outlet 14 into the room.

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 collecting coil 15,
Hot water is stored in a hot water storage tank 17, whereupon it is reheated as necessary by a hot water supply boiler 18 for additional heating and supplied to various places from a hot water supply pipe.

By the way, in a season such as summer when the temperature is high and heating is not required, it is necessary to discharge all the heated air heated by the roof panel 1 to the outside air and discard it. In this case, if the falling duct 10 which is one of the outflow sides is closed by the flow path switching damper 8 and the exhaust duct 9 which is the other one of the outflow sides is opened, the heated air is discharged from the handling box 5 through the exhaust duct. Discarded outside through 9. Since the heating air passes through the handling box 5 to heat the hot water removing coil 15, it is ensured that hot water can be obtained by using solar heat even at high temperatures such as in summer.

[0010]

In such a solar system house using heated air collected by sunlight as shown in FIG. 2, one end of an air flow path 2 having a roof slope just below a roof plate 1 is connected to an eaves tip. The roof is opened as an outside air inlet 3 and enters the air flow path 2 from the eaves portion and is heated by the roof panel 1 heated by sunlight.

Accordingly, when the external wind is strong, the wind acts as an air curtain for closing the outside air intake 3, and the air from the outside air intake 3 is not sufficiently taken in or the inside of the air flow path 2 is disturbed. May be done.

The hut attic 22, which is an attic space in which the ridge duct 4 as a heat collection box and the handling box 5 are installed, is generally a humid place where dew condensation or the like easily occurs.

An object of the present invention is to solve the above-mentioned disadvantages of the prior art, to prevent the inside of the heat collecting surface from being disturbed by external wind, to take in the air to be heated efficiently, and to make the back of the hut clear. It is an object of the present invention to provide a solar system house capable of automatically improving forced living by improving forced living.

[0014]

According to the present invention, in order to achieve the above object, an air passage having a roof slope is formed immediately below a roof shingle of a roof on the south side, and a ventilation hole at the back of the hut is provided on a portion other than the south side. Open, the back of the hut and the air flow path are partitioned by a heat insulating material, but a ventilation path is provided between the back of the hut and the lower end of the air flow path and parallel to the air flow path, The bottom of the cabin and the lower end of the air flow path are communicated with each other through the ventilation path, and the other end of the air flow path is communicated with a ridge duct serving as a heat collection box provided on the back of the cabin. A handling box having a built-in flow path switching damper is installed behind the hut, the inflow side of the handling box is connected to the ridge duct, and the outflow side is connected to the upper end of the falling duct, and the falling The lower end of the duct is Opening in the air circulation space between the concrete floor and the floor panel, providing a floor outlet from the air circulation space to the room, taking in outdoor air into the back of the hut from the ventilation port, the air in the back of the hut The roof heated by sunlight while moving along the roof gradient, sent to the lower end of the air flow path formed directly under the roof plate of the roof on the south through a ventilation path parallel to the air flow path Heat on a plate,
The gist of the present invention is to collect in the ridge duct, and then send the collected heat to the air circulation space between the heat storage soil concrete and the floor panel via the handling box and the falling duct.

[0015]

According to the present invention, since the air is taken into the air passage from the back of the cabin instead of directly from the outside, it is not affected by the external wind.

An air passage parallel to the air flow path is provided between the back of the hut and the lower end of the air flow path, and the lower end of the air flow path is communicated with the back of the hut and the lower end of the air flow path through this air flow path. The air from the back of the cabin is located close to the roof shingle and has the length of the ventilation path that has a heating effect. The distance moved along the roof gradient becomes longer, and the heating effect of the roof slab heated by sunlight can be improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 shows a solar system house 1 according to the present invention.
FIG. 4 is a vertical sectional side view showing an embodiment, in which the same components as those in FIG. 2 showing the conventional example are denoted by the same reference numerals.

The point that an air flow path 2 having a roof gradient is formed immediately below a roof plate 1 made of a metal plate such as a color iron plate is the same as the above-mentioned conventional example. This shingle 1 is a south facing roof, while
The ventilation port 25 of the roof hut back 22 is opened to a side other than the south side, for example, the north side.

The hut back 22 and the air flow path 2 are partitioned by a heat insulating material. A ventilation path 40 parallel to the air flow path 2 is provided between the hut back 22 and the lower end of the air flow path 2. Then, the back of the hut 22 and the lower end of the air flow path 2 are communicated with each other through the ventilation path 40.

The upper end of the air flow path 2 is communicated with a ridge duct 4 as a heat collection box made of a heat insulating material. A handling box 5 is installed between the ridge duct 4 and the falling duct 10. The lower end of the heat storage clay concrete
An opening is provided in an air flow space 13 between the floor panel 11 and the floor panel 12, and a floor outlet 14 is provided from the air flow space 13 to the room.

The ridge duct 4 and the handling box 5 are installed in the back of the hut 22. The handling box 5 has a backflow prevention damper 6, a fan 7 and a flow path switching damper 8 therein. One of the outlet sides of 8 is opened to the outside by an exhaust duct 9, and the other is connected to the upper end of a falling duct 10.

The inflow side of the backflow prevention damper 6 of the handling box 5 is connected to the ridge duct 4, and the inflow side of the backflow prevention damper 6 is also connected to the circulation duct 19 which is opened into the room by the suction port 20 at the ceiling or the like. The backflow prevention damper 6 is connected as a flow path switching damper for switching the flow path between the ridge duct 4 side and the circulation duct 19 side.

In the handling box 5, a hot water removing coil 15 is provided between the backflow prevention damper 6 and the fan 7,
The hot water coil 15 is connected to a hot water storage tank 17 by a circulation pipe 16, and a hot water supply boiler 18 is provided in the hot water storage tank 17 to connect a hot water supply pipe 21 connected to a bath, a washroom, and a kitchen.

An auxiliary heating coil 23 is provided between the fan 7 and the flow path switching damper 8.
Is connected to a heating / additional boiler 24 installed outdoors or the like by a circulation pipe 26. As the heating / additional boiler 24, a boiler dedicated to heating incorporated in the hot water supply boiler 18 can be used.

An auxiliary heating coil 39 is provided in the vicinity of the floor outlet 14 into the room, and these auxiliary heating coils 39 are connected to a circulation pipe 38.
Heating and additional cooking boiler which is the heating boiler
24.

Next, the method of use will be described. In the morning when sunlight does not hit the shingle 1, the air temperature in the ridge duct 4 is low. In this case, the backflow prevention damper 6 opens the circulation duct 19 side and closes the ridge duct 4 side. Also,
The flow path switching damper 8 closes the exhaust duct 9 side, and connects the fan 7 and the falling duct 10. When the fan 7 is driven in this state, cool air is discharged from the outlet 14 into the room, which has the opposite effect to heating. Therefore, first, the heating / additional boiler 24 is ignited, and the auxiliary heating coil 23 and the auxiliary heating coil 39 are heated.

Thus, the air entering the handling box 5 from the room via the circulation duct 19 is supplied to the auxiliary heating coil.
The air is heated at 23, becomes warm air, descends the falling duct 10, and is further heated by the auxiliary heating coil 39 when it is blown into the room from the air outlet 14, thereby performing heating.

When the sunlight hits the roof panel 1 and the temperature in the ridge duct 4 becomes higher than the set temperature, the backflow prevention damper 6 reverses, opens the ridge duct 4 side, and closes the circulation duct 19 side. Then, the fan 7 starts and starts collecting heat. The outside air is first entered by the fan 7 from the ventilation opening 25 into the roof hut 22, and the air in the hut 22 is passed through the air passage 2.
Into the lower end of the air passage 2 formed directly below the roof shingle 1 of the southern roof through an air passage 40 parallel to the roof shingle 1 where it rises along the roof slope and is heated by sunlight. It is heated and collected in the wing duct 4 before entering the handling box 5.

Even when the heat collection is started, the auxiliary heating coil 23 and the auxiliary heating coil 39 are still heating. The heating / additional boiler 24 that heats the auxiliary heating coil 23 and the auxiliary heating coil 39 automatically stops via the control device when the room temperature exceeds the set temperature, and thereby the auxiliary heating coil 23 and the auxiliary heating coil The heating in the coil 39 is also stopped.

The heated air flows down from the handling box 5 through the falling duct 10 to be stored in the heat storage soil concrete 11.
Into the air circulation space 13 between the floor panel 12 and the floor panel 12
Heating under the floor directly via 12, storing heat in the thermal storage clay concrete 11, and directly blowing out the room as warm air from the outlet 14, the room has a room temperature The water gradually rises, but hot water is not yet collected until the room temperature rises too much.

When the room temperature reaches the set temperature for hot water collection, the pump in the hot water storage tank 17 operates and the hot water starts to circulate with the hot water removal coil 15 via the circulation pipe 16. In order to operate the pump, it is necessary that the temperature in the handling box 5 and the temperature in the hot water storage tank 17 have a difference of a certain temperature or more.
This temperature difference is considerable in the morning of the start of hot water collection, but as the hot water circulates in the hot water coil 15, the temperature in the hot water storage tank 17 rises rapidly and the pump stops when the temperature difference drops below a certain level. , Hot water is stopped.

The heating boiler 24, the auxiliary heating coil 23 and the auxiliary heating coil 35 are automatically driven when the room temperature does not exceed the set temperature, and the auxiliary heating coil is used at night or when the weather is poor. 23 and auxiliary heating coil 39
Can be heated.

When the fan 7 is driven, the fan 7
When the temperature rises, a rising air current is generated in the pipe 31 by a chimney effect, and the motor in the case 30 is cooled by the flow of air flowing through the handling box 5 from below to above.

On the other hand, the backflow prevention damper 6 is provided with a circulation duct
Close the side and open the ridge duct 4 side. Further, the flow path switching damper 8 closes the fan 7 and the falling duct 10 side, and connects the fan 7 and the exhaust duct 9 side.

When the fan 7 is driven in this manner, the heated air collected in the roof hut 22 from the ventilation opening 25 and further into the ridge duct 4 through the air flow path 2 enters the handling box 5 and is supplied with hot water. After the coil 15 is heated, it flows through the exhaust duct 9 and is discarded outside. At this time, the air sent directly from the fan 7 to the exhaust duct 9
The attraction force is applied to the floor 10, and the air under the floor is sucked into the exhaust duct 9 through the falling duct 10, so that not only the ventilation of the hut back 22 but also the ventilation under the floor can be performed at the same time.

[0036]

As described above, in the solar system house of the present invention, when the heating air collected by sunlight is taken in and used for heating, the inside of the heat collecting surface is disturbed by the external wind. Without heating, air to be heated can be efficiently taken in, and the hut can be automatically forcibly ventilated to improve comfort. In addition, because air was introduced into the lower end of the air flow path,
Air from the back of the hut moves along the roof slope by the length of the ventilation path that is located near the roof plate and has a heating effect, and the heating effect of the roof plate heated by sunlight is reduced. It can be improved.
