Description

[Technical field]

[0001] The present invention relates to a building in which an intake port connected to an air duct is provided in a room. [Background technology]

[0002] It is common for rooms in a building to be equipped with air intakes that are connected to ventilation ducts such as air circulation ducts for air conditioning units and smoke exhaust ducts for exhausting smoke from inside the room to the outdoors in the event of a fire.

[0003] Patent Document 1 describes a building in which an intake port connected to an air circulation duct of an air conditioner is provided on the ceiling of a room. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2008-14557 A Summary of the Invention [Problem to be solved by the invention]

[0005] For example, in buildings used as restaurants and other eateries, there are known buildings in which the ceiling of the room is arched to enhance the aesthetic appearance of the room. When providing an air intake in the room of such a building, it is possible to configure the air intake to open in the arched portion of the ceiling and extend horizontally from the opening toward the ventilation duct.

[0006] However, if the air intake of the above configuration is installed in the arch-shaped part of the ceiling, there is a problem in that the internal structure such as the ventilation duct can be seen through the opening of the air intake from inside the room, which may detract from the aesthetic appearance of the room.

[0007] The present invention has been made in consideration of such problems, and its object is to provide a building that makes it possible to install an intake port in an arch-shaped ceiling without spoiling the aesthetic appearance of the room. [Means for solving the problem]

[0008] The building of the present invention is a building in which an intake port connected to an air duct is provided in a room, the ceiling of the room being arched, the ceiling having a first opening in the shape of a horizontally extending slit, a first intake port extending horizontally from the first opening toward the air duct, and a second opening in the shape of a horizontally extending slit arranged at a distance below the first opening, a second intake port extending horizontally from the second opening toward the air duct.

[0009] In the building of the present invention, in the above-mentioned configuration, it is preferable that an entrance / exit to the living room is provided below the second air inlet, and the downwardly extending wall above the entrance / exit has a lower opening that opens to the underside of the downwardly extending wall, and a downwardly extending air inlet is provided extending from the lower opening toward the ventilation duct. Effect of the Invention

[0010] According to the present invention, it is possible to provide a building in which an air intake can be provided in an arched ceiling without spoiling the aesthetic appearance of the room. [Brief description of the drawings]

[0011] [Figure 1] FIG. 2 is a floor plan of a portion of a building according to one embodiment of the present invention in which rooms are provided. [Diagram 2] FIG. 2 is a cross-sectional view taken along the line AA in FIG. [Diagram 3] FIG. 3 is a cross-sectional view taken along line BB in FIG. [Figure 4] FIG. 4 is a cross-sectional view taken along line CC in FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] Hereinafter, a building according to one embodiment of the present invention will be described in detail with reference to the drawings.

[0013] A building 1 according to this embodiment shown in FIG. 1 is used as a restaurant, and includes a living room 2 which is used as a private room for meals.

[0014] As shown in Fig. 2, the ceiling 3 of the living room 2 is arched. More specifically, the ceiling 3 is smoothly curved between one side wall 4a of the living room 2 and the other side wall 4b opposite the side wall 4a, so that the ceiling height is highest at the center between the side walls 4a and 4b and lowest at the joint between the side walls 4a and 4b. The arch shape of the ceiling 3 shown in Fig. 2 is substantially uniform between the side wall 4c at the right end and the side wall 4d at the left end of the living room 2 in Fig. 1.

[0015] In addition, as long as the ceiling 3 is arch-shaped, it is not limited to the shape shown in Figure 2. For example, the ceiling 3 may have a flat portion with a constant ceiling height in a predetermined range including the center position between side walls 4a and 4b, and on both sides of the flat portion, there are curved portions so that the ceiling height gradually decreases toward the connecting portion with side wall 4a or the connecting portion with side wall 4b.

[0016] The ceiling 3 is a so-called suspended ceiling, which is formed of curved plate material of a specified thickness, and is suspended by a plurality of hanging bodies 6 such as rods from a support 5 supported by the framework (not shown) of the building 1. A configuration in which a heat insulating material 3a such as glass wool is layered on the upper surface of the ceiling 3 may be used.

[0017] As shown in FIG. 1, in this embodiment, the living room 2 is configured so that it can be partitioned into two spaces by a plurality of wall bodies 11 constituting the movable partition 10 as necessary. Furthermore, when the living room 2 is partitioned by the plurality of wall bodies 11 constituting the movable partition 10, it has a first entrance 7a located on one side of the movable partition 10 of the living room 2 and a second entrance 7b located on the other side. Furthermore, when the living room 2 is partitioned by the plurality of wall bodies 11 constituting the movable partition 10, it has a first cloakroom 8a located on one side of the movable partition 10 of the living room 2 and a second cloakroom 8b located on the other side. An entrance 9 to the first cloakroom 8a is provided between the living room 2 and the first cloakroom 8a, and the entrance 9 is provided with a sliding door 9a.

[0018] The living room 2 may be configured without the movable partition 10.

[0019] As shown in Figures 3 and 4, the living room 2 is provided with an intake port 20. An air duct 21 extending in the vertical direction along the side wall 4a is installed on the back side of the ceiling 3, and the intake port 20 is connected to the air duct 21. The air duct 21 is connected to a horizontal duct 22 penetrating the side wall 4a, and is connected to an air circulation duct 23a and a smoke exhaust duct 24 of an air conditioning device (air conditioner) 23 via a switching damper 22a provided in the horizontal duct 22.

[0020] In a normal state, the ventilation duct 21 is connected to the air circulation duct 23a by the switching damper 22a, and the connection to the smoke exhaust duct 24 is cut off. As a result, air inside the living room 2 is sent from the intake port 20 through the ventilation duct 21, the horizontal duct 22, and the air circulation duct 23a to the air conditioning device 23, and the temperature and humidity are adjusted by the air conditioning device 23. The air whose temperature and humidity have been adjusted by the air conditioning device 23 is sent through the air circulation duct 23b to the air outlet 25 (see FIG. 3) provided on the ceiling 3 of the living room 2, and is blown out from the air outlet 25 into the living room 2. Note that, although the air outlet 25 is provided on the ceiling 3 of the living room 2 in this embodiment, its installation position can be changed in various ways.

[0021] On the other hand, in the event of a fire, the ventilation duct 21 is disconnected from the air circulation duct 23a by the switching damper 22a and is connected to the smoke exhaust duct 24. This allows smoke inside the living room 2 that has broken out due to a fire to be exhausted from the intake port 20 through the ventilation duct 21, the horizontal duct 22, and the smoke exhaust duct 24 to the outdoors.

[0022] In the building 1 of this embodiment, the air inlet 20 has a first air inlet 20A and a second air inlet 20B each provided in the arch-shaped ceiling 3.

[0023] The first air inlet 20A has a first opening 30A that is disposed in a curved portion of the ceiling 3 and opens into the ceiling 3. The first opening 30A has a slit shape that extends horizontally, that is, a horizontally long rectangular shape whose horizontal dimension is larger than its up-down dimension. The first air inlet 20A extends horizontally from the first opening 30A toward the ventilation duct 21. That is, the first air inlet 20A has a square tube-shaped first ventilation section 31A that extends horizontally from the first opening 30A to the ventilation duct 21.

[0024] The second suction port 20B is provided below the first suction port 20A with a gap therebetween. The second suction port 20B has a second opening 30B that is disposed below the first opening 30A with a gap therebetween in the curved portion of the ceiling 3 and opens in the ceiling 3. The second opening 30B has a slit shape extending horizontally like the first opening 30A, that is, a horizontally elongated rectangular shape whose horizontal dimension is larger than its vertical dimension. The second suction port 20B extends horizontally from the second opening 30B toward the ventilation duct 21. That is, the second suction port 20B has a square tube-shaped second ventilation section 31B that extends horizontally from the second opening 30B to the ventilation duct 21.

[0025] The horizontal width dimension of the first opening 30A and the first ventilation section 31A of the first suction port 20A is the same as the horizontal width dimension of the second opening 30B and the second ventilation section 31B of the second suction port 20B. In addition, the vertical height dimension of the first ventilation section 31A of the first suction port 20A is the same as the vertical height dimension of the second ventilation section 31B of the second suction port 20B. In other words, the flow path cross-sectional area of ​​the first suction port 20A and the flow path cross-sectional area of ​​the second suction port 20B are the same. In addition, the flow path cross-sectional areas of the ventilation duct 21 and the horizontal duct 22 are larger than the sum of the flow path cross-sectional area of ​​the first suction port 20A and the flow path cross-sectional area of ​​the second suction port 20B.

[0026] The air inlet 20 provided in the living room 2 needs to have a predetermined flow cross-sectional area in order to effectively function the air circulation duct 23a or the smoke exhaust duct 24 of the air conditioning device 23. In the building 1 of this embodiment, the air inlet 20 provided in the living room 2 is divided into the first air inlet 20A and the second air inlet 20B, each of which opens into the ceiling 3, so that the first air inlet 20A and the second air inlet 20B can each have a flow cross-sectional area that is half the predetermined flow cross-sectional area. Therefore, when the horizontal width is constant, the height dimension of the first air inlet 20A and the height dimension of the second air inlet 20B can each be made lower than when the air inlet 20 is configured to have only one opening.

[0027] In this manner, in the building 1 according to this embodiment, the air inlet 20 provided in the living room 2 is divided into the first air inlet 20A and the second air inlet 20B, each of which opens into the ceiling 3, so that the height dimension of the first air inlet 20A and the height dimension of the second air inlet 20B are each lower than when the air inlet 20 is configured to have only one opening, making it difficult to see the internal structure such as the ventilation duct 21 from inside the living room 2 through the first opening 30A of the first air inlet 20A or the second opening 30B of the second air inlet 20B. This makes it possible to prevent the aesthetics of the living room 2 from being impaired, even when the air inlet 20 is provided in the arched ceiling 3.

[0028] Furthermore, in the building 1 of this embodiment, as described above, it is possible to prevent a decrease in the aesthetic appearance of the room 2 while securing the specified flow path cross-sectional area required for the air circulation duct 23a or the smoke exhaust duct 24 of the air conditioning unit 23 to function effectively, so that it is possible to sufficiently secure the air conditioning function or smoke exhaust function in the room 2 while enhancing the aesthetic appearance of the room 2 having an arched ceiling 3.

[0029] In this embodiment, the first suction port 20A and the second suction port 20B are provided above the entrance 9 of the living room 2, and each of them has the same width as the entrance 9. The entrance 9 provided below the first suction port 20A and the second suction port 20B is in the form of a passageway recessed toward the outside of the room from the inner surface of the side wall 4a facing the room inside, and a door 9a is arranged on the outside of the lowered wall 4e that defines the passageway-like entrance 9.

[0030] In the building 1 of this embodiment, a downward suction port 20C is provided in a lowered wall 4e that defines the entrance 9.

[0031] The downward suction port 20C has a lower opening 30C that opens on the lower surface of the downward wall 4e. Although not shown in detail, the lower opening 30C may have a slit shape similar to the first opening 30A to the second opening 30B. The downward suction port 20C extends from the lower opening 30C toward the ventilation duct 21. In this embodiment, the downward suction port 20C extends from the lower opening 30C toward the ventilation duct 21 in the up-down direction. That is, the downward suction port 20C has a lower ventilation portion 31C in a square tube shape that extends in the up-down direction from the lower opening 30C to the ventilation duct 21.

[0032] In this way, by providing the downward inlet 20C in addition to the first inlet 20A and the second inlet 20B in the living room 2, it is possible to further reduce the flow path cross-sectional area of ​​the first inlet 20A to the second inlet 20B, and it is possible to further reduce the height dimension of the first inlet 20A and the height dimension of the second inlet 20B. This makes it even more difficult to see the internal structure such as the ventilation duct 21 from inside the living room 2 through the first opening 30A of the first inlet 20A to the second opening 30B of the second inlet 20B, and it is possible to more effectively prevent the aesthetics of the living room 2 from being deteriorated by providing the inlet 20 in the arch-shaped ceiling 3.

[0033] The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit and scope of the present invention.

[0034] For example, in the above embodiment, the building 1 is used as a restaurant, but this is not limited thereto, and the building may be used for other purposes such as an office or a residence, as long as it has a room 2 with an arched ceiling 3.

[0035] In the above embodiment, the ventilation duct 21 to which the suction port 20, i.e., the first suction port 20A and the second suction port 20B are connected, is configured to be selectively connected to the air circulation duct 23a and the smoke exhaust duct 24 of the air conditioning device 23, but it may be configured to be connected to only one of the air circulation duct 23a and the smoke exhaust duct 24 of the air conditioning device 23. In addition, the ventilation duct 21 to which the suction port 20, i.e., the first suction port 20A and the second suction port 20B are connected, may be configured to be connected to a duct used for a purpose other than the air circulation duct 23a and the smoke exhaust duct 24 of the air conditioning device 23.

[0036] Furthermore, in the above embodiment, the flow path cross-sectional area of ​​the first suction port 20A and the flow path cross-sectional area of ​​the second suction port 20B are the same, but they may be different. In this case, the horizontal width dimension of the first opening 30A and the first ventilation section 31A of the first suction port 20A may be the same as the horizontal width dimension of the second opening 30B and the second ventilation section 31B of the second suction port 20B, while the vertical height dimension of the first ventilation section 31A of the first suction port 20A may be different from the vertical height dimension of the second ventilation section 31B of the second suction port 20B.

[0037] Furthermore, in the above embodiment, the downward suction port 20C is provided in the lowered wall 4e that defines the entrance 9, but the downward suction port 20C may not be provided. [Explanation of symbols]
