Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilation system for a building such as a house.

[0002]

2. Description of the Related Art Some buildings such as houses have an attic storage room at the back of a hut or a lower roof. However, unlike a living room, an attic storage room has a severe temperature and humidity environment. However, the conventional ventilation of the attic storage room was only equipped with an individual exhaust fan, and did not consider air supply.

[0003] Accordingly, since the temperature in the attic storage room becomes extremely high in summer, for example, when the temperature in the attic storage room becomes about 50 ° C, countermeasures against hot air especially in the attic storage room in summer are inadequate, and the storage in the attic storage room becomes insufficient. There is a risk of deterioration and deformation, and it is necessary to limit the items to be stored. Even if devices such as antiques and ladders can be stored in the attic storage room, there was a problem in storing documents such as books.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and is intended to provide sufficient measures against hot air in summer in an attic storage room by ventilation.

[0005]

The technical means of the present invention for solving this technical problem is that an air supply means is provided in the attic storage room. Therefore, the air in the room can be sucked into the attic storage room and the hot air in the attic storage room can be effectively discharged to the outside.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes a two-story house having a living room 2 on the first floor, a staircase 3, a living room 4 on the second floor, and a stair hall 5, and an attic storage room (attic storage room) 7) is provided.

[0007] A forced exhaust fan 9 is provided on the side of the attic storage room 7, and the air in the attic storage room 7 is forcibly discharged to the outside by the forced exhaust fan 9. Entrance door (ladder and ceiling lid) 11 provided at the bottom of the attic storage room 7
In addition, a grill 12 as an air supply means is provided, and air is allowed to flow from the stair hall 5 to the attic storage room 7 through the grill 12. A ventilation opening 13 communicating with the outside air is provided in the attic 6.

According to the above embodiment, the attic storage room 7
Is sufficiently ventilated by natural air supply by the grill 12 and forced exhaust by the forced exhaust fan 9 (third type ventilation), whereby the room of the attic storage room 7 approaches the room temperature of the living room 4 and the staircase hall 5, and Hot air countermeasures can be performed sufficiently. In addition, the inside of the attic 6 is provided with forced air supply by the forced exhaust fan 9 and natural exhaust by the ventilation port 13 (second type ventilation).
Thus, the temperature of the ceiling surface of the living room 4 on the second floor can be lowered. In addition, a duct is not required, and the construction is reduced and the cost is reduced. Moreover, since the hot air does not stay on the second floor, the living environment becomes more comfortable.

FIG. 2 shows another embodiment, in which an attic storage room (lower attic storage room) 17 is provided on an attic (lower attic) 16 on the first floor.
Is provided. A forced exhaust fan 19 is provided on the outer side of the attic storage room 17, and the air in the attic storage room 17 is forcibly discharged to the outside by the forced exhaust fan 19. A louver 22 serving as an air supply means is provided in an entrance door 21 inside the attic storage room 17, and air is allowed to flow into the attic storage room 17 from a living room on the second floor or the like through the louver 22. The attic 16 is provided with a ventilation port 23 communicating with the outside air.

According to the above-described embodiment, as in the case of the above-described embodiment, the attic storage room 17 is sufficiently ventilated by natural air supply by the grill 22 and forced exhaust by the forced exhaust fan 19 (third type ventilation). Ventilation, thereby the attic storage room 1
The room No. 7 approaches the room temperature of the living room or the like, and hot air countermeasures in summer can be sufficiently performed. Further, the inside of the attic 16 is effectively ventilated by forced air supply by the forced exhaust fan 19 and natural exhaust by the ventilation port 23 (second type ventilation).

FIG. 3 and FIG. 4 show another embodiment, which is located above the first floor living room 2 of the house 1 and outside the second floor living room 4.
An attic storage room (lower roof storage room) 27 is provided.
A forced air supply means 28 such as a blower or a pump is provided below the attic storage room 27, and an air duct 29 is provided vertically in the north side of the house 1. , Cold air on the north side is forcibly sucked into the attic storage room 27.

As shown in FIG. 4, as a measure against moisture in winter, an entrance door 31 is provided between the attic storage room 27 and the second floor living room 4, and vents are provided above and below the entrance door 31. (Gully, etc.) 33 and 34 are provided, air is allowed to flow from the second floor living room 4 to the upper side of the attic storage room 27 through the upper ventilation opening 33, and the second floor living room from the lower side of the attic storage room 27 through the upper ventilation opening 33. 4 to send cold air. A vent space (slaning, perforated plate, etc.) 37 is provided for the purpose of preventing the storage object 39 from being in close contact with the wall 35 and the floor 36 of the attic storage room 27. Further, in order to prevent surface dew condensation on the finishing material, a moisture absorbing finishing material is used for the finishing material of the wall 35 and the floor 36.

According to the above embodiment, the forced air supply means 2
In order to forcibly take in the low temperature air of the north side etc. by 8 and discharge the hot air in the attic storage room 27 to the outside, the attic storage room 27 can be sufficiently ventilated by the second type ventilation, As a result, the temperature in the attic storage room 27 can be effectively reduced, and sufficient measures against hot air in summer can be taken.

In winter, warm air from the second floor living room 4 is taken in from the upper ventilation port 33 of the entrance door 31 and passes through the ventilation space 37 provided on the wall 35 and floor 36.
Air circulates from the lower part of the entrance door 31 to the room. For this reason, in the winter season, it is possible to prevent the inside of the attic storage room 27 from having a lower temperature than the inside of the second-floor living room 4 and also prevent the flow of steam from the inside of the living room 4.

Therefore, in the summer and winter, the high temperature and dew condensation which deteriorate or deform the attic storage room 27 can be prevented, and the range of the storage items 39 which can be stored in the attic storage room 27 without damaging the storage items 39 is increased. The life of the attic storage room 27 itself is also extended.

[0016]

According to the present invention, since the air supply means is provided in the attic storage room, the outside air can be sucked into the attic storage room and the hot air in the attic storage room can be effectively discharged to the outside. In the attic storage room, measures against hot air in summer become sufficient, and it becomes possible to store documents such as books in addition to antiques and ladders in the attic storage room.
