Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof structure, and more particularly to a roof structure having a structure for ventilating a building room.

[0002]

2. Description of the Related Art In order to obtain a good indoor environment, various ventilation means are used in buildings such as houses. In particular, in a residential building in a cold region or the like, airtightness is required to improve heat retention in a room, and therefore dirty air in the room needs to be exhausted using a predetermined ventilation means.

As such a ventilation means, a ventilation fan is generally installed on the outer wall or window of a building, and this ventilation fan is used to replace the air in the room.

[0004]

When indoor ventilation is performed by the ventilation fans installed on the walls and windows as described above, the size of each ventilation fan should be relatively small in view of the installation space. Becomes Therefore, when the indoor space is large, it is necessary to increase the number of ventilation fans in accordance with the size of the indoor space. However, this may impair the design of the outer ring of the building, so the number is limited.

Providing a large-scaled ventilation fan corresponding to the size of the room also results in an increase in the size of the space where the ventilation fan is installed, resulting in a loss of effective use of walls and space.

[0006] The present invention has been made in view of the above problems, and an object thereof is to efficiently perform ventilation without narrowing an indoor use space in a cold region or the like where a high hermeticity of a building is required. It is to provide a roof structure that can be used.

[0007]

In order to achieve the above object, a roof structure according to the present invention comprises a roof sloping portion having a predetermined slope and a hut back portion formed below the roof sloping portion. In the roof structure having, a part of the back of the shed is a back of a shed having a ceiling structure of a room below the shed, and the back of the shed adjacent to the back of the shed is a lower room. And a floor part that constitutes a partition, and a partition wall part that partitions the space between the back of the blow-out structure and an air circulation part, a side wall part that provides an outside air circulation part, and the air circulation part. Ventilation means for exchanging at least a part of the indoor air that has flowed in with the outside air.

[0008]

According to the roof structure having the above structure, a part of the back of the hut below the sloped part of the roof has a blow-through structure. That is, the structure of the ceiling part of the room below the back of the hut is partially removed, and the structure is blown from the inside of the room to the inner side surface of the room slope as it is. Therefore, in the back of the shed structure (hereinafter referred to as "the back of the shed"),
Warm and dirty air rises indoors.

The back of the hut adjacent to the back of the stairwell is partitioned by a partition wall having an air circulation portion, and a floor (a ceiling of a lower room) is formed. Therefore, one space is formed by the roof side wall portion such as the floor portion, the partition wall, the roof slope portion, and the gable wall. Ventilation means is provided in the space, and the dirty air that has risen to the back of the blow-through hut can flow into the space through the air circulation unit and can ventilate the air from the outside.

As described above, according to the present invention, the ventilation means is installed in the back of the shed between the ceiling portion and the roof sloping portion, and the rising dirty air can be efficiently ventilated. Therefore, for example, even when a large ventilating means having a large indoor space is required, the ventilating device can be installed in the back of the partitioned shed, and the utilization space in the room is not narrowed.

Further, since the warm air that has risen is ventilated, it is possible to improve the efficiency in terms of room temperature by installing a device that uses this warm air and performs heat exchange with the inhaled outside air. Good ventilation is possible.

[0012]

Embodiments of the present invention will now be described in detail with reference to the drawings.

FIG. 1 shows an example in which a roof structure according to the present invention is used for a building in a cold region.

As shown, the building 100 has an outer wall 1
A parapet 12 is formed at the upper end of the parapet 0, and an inclined portion 14 that is slightly inclined downward from the inner side surface of the parapet 12 toward the inside of the building is formed. Then, between the troughs 16 are formed roof inclined portions 18a and 18b which are inclined upward toward the central portion.

[0015] Such a roof structure is a structure for effectively preventing a dangerous situation in which the snow falls downward even when snow is accumulated on the roof in a cold region.
That is, the gradually falling snow is melted by, for example, a heater in the part of the gutter 16 and is then discharged from the gutter along a vertical gutter (not shown) passing through the room.

The characteristic construction of this embodiment is that the roof sloped portion 18
That is, a part of the back of the shed located below a and 18b is divided into a back shed 200 and a back of the ventilation shed 300.

In the present embodiment, this division is divided into two parts on the left and right from the central portion of the roof, that is, from the roof top. The portion of the backstory hut 200 is not provided with a ceiling for partitioning the back of the hut from the lower room 400, and is completely blown from the indoor space 400 to the inner surface of the roof slope 18. Next, the ventilation hut back 300 is provided with a floor, that is, a ceiling 20 for partitioning the interior space 400, and a partition wall 22 is provided between one end of the ceiling 20 and the roof top 19. Are formed.
As a result, the roof sloped portion 18a, the ceiling portion 20, the partition wall 22, and the wall portions (not shown) that follow the both sides of the roof inclined portion 18a form one partitioned ventilation hut back 300.

Further, the partition wall 22 is formed with an opening 24 as an air circulating portion. And the back of the ventilation hut 3
Ventilation means 26 that can satisfactorily ventilate the entire indoor space 400 is installed inside 00.

The ventilation means 26 can be constructed by attaching a ventilation fan to a side wall portion (not shown), that is, a side wall portion, for example.

As described above, the air warmed in the indoor space 400 and rising as dirty air is used as the ventilation means 2.
6 through the opening 24 for air circulation to the back of the ventilation shed 300
It flows in and is exchanged with outside air. Therefore, dirty air can be efficiently ventilated, and the back of the ventilation shed 30
Since a device for ventilation can be installed in 0,
Even a large device that can accommodate the space of the indoor space 400 can be used without narrowing the indoor space below.

Next, a preferred configuration example of the ventilation cottage rear part 300 will be described with reference to FIGS.

FIG. 2 shows the exterior of the ventilation hut back 300, showing the configuration of the one that is installed at the outermost part of the building. That is, the side wall 28 on the front side in the figure constitutes the end wall of the building, and in this embodiment, an opening (not shown) is formed, and the louver 30 is formed in the opening.
Is attached. On the other hand, the opening 2 is also formed in the partition wall 22.
The grid-like member 32 is attached so as to cover 4.

FIG. 3 is an explanatory view showing the internal structure of the ventilation hut back 300 having such an external structure.

As shown in the figure, a ventilation fan 34 having a heat exchange function is attached to the wall surface of the side wall 28 of the roof portion. The ventilation fan 34 sucks the air in the room below through the opening 24 by the suction portion (not shown), while the duct 3
6 is inhaling the outside air. Then, after the heat exchange between the warmed indoor air and the outside air passing through the pipe arranged in the ventilation fan 34, the outside air is sent to the heater 40 through the duct 38. Exhaust gas from the ventilation fan 34 is discharged from the louver 30 to the outside through a blow-out port (not shown).

The heater 40 has two ducts 42 and 44.
Both of these ducts are provided with their open ends at the lower part of the opening 24 and suck a part of the high temperature air rising from the room. Then, the outside air from the ventilation fan 34 and the room air sucked in the ducts 42 and 44 are mixed to supply the air of appropriate temperature from the warm air duct 46 to the room.

FIG. 4 also shows another attic 400 adjacent to the ventilation attic 300.

A boiler 48 is installed inside the hut back 400. Such a boiler 48 is usually installed in an outdoor storage room or the like on the first floor of a building, but by installing it in the back 400 of the hut, it is effectively installed without narrowing the space outside the first floor. Is planned.

The boiler 48 is constructed so as to be able to supply hot water to the heater 40 shown in FIG. 3, for example, and is provided with two pipes 50, and the back of the ventilation shed 300 shown in FIG. Is connected to the heater 40.

According to the above-described embodiment, the dirty air that has risen to the portion of the attic back space 200 due to the temperature rise is sucked by, for example, the ventilation fan 34 shown in FIG.
Be ventilated with outside air. At this time, since the ventilation fan 34 has a heat exchange function, the heat of the dirty air is used to warm the outside air taken in, and the heat of the warmed indoor air is also effectively used.

Since a large space behind the hut can be used as an installation area for ventilation means, it is not necessary to provide a space for a ventilation device on the first floor of the building,
It becomes possible to install a relatively large-scale ventilation device in accordance with the size of the indoor space 400 without hindering effective use of the space.

The present invention is not limited to the configuration of the above embodiment, and various modifications can be made within the scope of the gist of the invention. For example, the ventilation means is not limited to the one described in the above embodiment, and various kinds of ventilation means can be used as long as they have a predetermined outside air suction force and a function capable of simultaneously exhausting air. .

[0032]

As described above, according to the roof structure of the present invention, dirty air rising from the interior of a building can be efficiently ventilated in the back of a shed.
Further, since the ventilation means is installed in the back of the hut, it is possible to install even a relatively large-sized device without narrowing the indoor and outdoor space on the first floor.
