JP 2001-304641 A

The shoe cabinet ventilation system described in Patent Document 1 uses a ventilation fan to forcibly exhaust the air inside the shoe cabinet, and it is necessary to secure space to install the ventilation fan in the storage space inside the shoe cabinet. This poses the problem of reducing the storage space for footwear inside the shoe cabinet.

The present invention was made in consideration of the above problems, and its purpose is to provide a building that can ventilate the shoe cupboard while ensuring ample storage space for footwear.

A building according to one aspect of the present invention includes a floor provided with an underfloor ventilation duct for underfloor ventilation, an exterior wall provided with an in-wall ventilation duct for in-wall ventilation, a shoe cabinet provided with a storage space for footwear and arranged on the floor, and an intake duct that takes in air from the underfloor ventilation duct to the storage space . The storage space communicates with the underfloor ventilation duct and also communicates with the in-wall ventilation duct , and the floor is provided with a plurality of underfloor ventilation openings that communicate the underfloor ventilation duct with an outside air space, and the intake duct is provided with a first duct opening facing one of the plurality of underfloor ventilation openings and a second duct opening facing the other of the plurality of underfloor ventilation openings .

With this configuration, air can be taken into the storage space of the shoe cabinet from the underfloor ventilation duct. After flowing through the storage space, the air is discharged into the ventilation duct in the wall, expelling odors and moisture from within the storage space. In this way, the ventilation ducts in the floor and wall can be used to ventilate the shoe cabinet, so there is no need to install a ventilation fan. Therefore, the storage space in the shoe cabinet does not become narrower due to the installation of a ventilation fan, and the shoe cabinet can be ventilated while maintaining a large storage space.

The wind direction in the underfloor ventilation ducts may change depending on the season, etc. In other words, the state may change from one underfloor ventilation opening where air is taken in through one underfloor ventilation opening and exhausted through another underfloor ventilation opening to another state where air is taken in through another underfloor ventilation opening and exhausted through the first underfloor ventilation opening. In response to this, by providing duct openings facing each underfloor ventilation opening, air can be taken into the intake duct regardless of changes in wind direction.

In the above-mentioned building, the first duct opening and the second duct opening may overlap the underfloor ventilation opening in the vertical direction and have a smaller vertical dimension than the underfloor ventilation opening.

With this configuration, a portion of the air taken into the underfloor ventilation duct can be guided to the storage space by the intake duct, while the remainder can be circulated into the underfloor ventilation duct. This allows ventilation inside the shoe cupboard while maintaining the ventilation function under the floor.

In the above-mentioned building, the intake duct may include a partition section that prevents air from passing from one of the first duct opening and the second duct opening to the other.

This configuration prevents air from leaking out of the intake duct, so the air taken into the intake duct can be guided more reliably to the storage space.

In the above-mentioned building, the partition may include a guide section that guides the air taken into the intake duct to the storage space.

This configuration makes it easier to guide the air taken into the intake duct into the storage space.

In the above-mentioned building, the distance between the first duct opening and one of the underfloor ventilation openings may be determined so that a portion of the air taken into the underfloor ventilation duct from one of the underfloor ventilation openings is taken into the intake duct from the first duct opening, and the remainder of the air flows through the underfloor ventilation duct without being taken into the intake duct.

This configuration allows ventilation inside the shoe cupboard while maintaining the ventilation function under the floor.

In the above-mentioned building, a filter may be attached to the first duct opening and the second duct opening.

This configuration helps prevent insects, dust, etc. from entering the storage space of the shoe cabinet.

In the above-mentioned building, the floor may be provided with an intake port to which the intake duct is attached. The intake ports may be provided in a plurality of locations spaced apart from one another in the surface direction of the exterior wall, or may have a shape that extends in the surface direction.

This configuration allows air for underfloor ventilation to be drawn into the storage space more efficiently.

In the above-mentioned building, the shoe cabinet may include a plurality of shelves arranged at intervals from each other in the vertical direction in the storage space. The lowest shelf among the plurality of shelves may be configured to guide air taken into the storage space from the underfloor ventilation duct to the area of the storage space on the exterior wall side. The plurality of shelves may be arranged from the lower shelf side to the upper shelf side such that the end on the exterior wall side approaches the exterior wall.

This configuration allows the air taken into the storage space to flow evenly through each area between the shelves, ensuring thorough ventilation on each level.

In the above-mentioned building, at least one of the plurality of shelves may have a claw portion in which the end facing the exterior wall is folded back toward the lower level.

This configuration allows air drawn into the storage space to be efficiently drawn into the area between the shelves.

In the above-mentioned building, the shoe cabinet may include a door that opens and closes the storage space and is provided on the opposite side of the exterior wall with the storage space in between. A gap that allows ventilation may be provided between the inner surface of the door and the shelf board in the storage space.

This configuration ensures that the area of the storage space facing the door can also be ventilated.

In the above building, the door may have an airtight structure.

This configuration allows ventilation inside the shoe cabinet while preventing odors from leaking into the indoor space.

As is clear from the above explanation, the present invention can provide a building that can naturally ventilate the inside of a shoe cupboard while ensuring ample storage space for footwear.

FIG. 2 is a diagram showing a schematic configuration of an intake duct in the building. A plan view for explaining the position of the air intake in a building according to embodiment 2 of the present invention.

The following describes in detail the building according to an embodiment of the present invention with reference to the drawings.

(Embodiment 1)
First, the configuration of a building 1 according to a first embodiment of the present invention will be described with reference to Figures 1 to 3. The building 1 is, for example, a house, and has a structure capable of ventilating a shoe cabinet 30 by utilizing air passages for underfloor ventilation and in-wall ventilation. Figure 1 is a cross-sectional view taken along the vertical direction, showing a state in which the shoe cabinet 30 is installed at a connection between a floor 10 and an exterior wall 20. As shown in Figure 1, the building 1 mainly comprises a floor 10, an exterior wall 20, a shoe cabinet 30, and an intake duct 40. Each component will be described below.

The floor 10 is provided with an underfloor ventilation duct S1 for underfloor ventilation. The floor 10 has a heat-insulating structure and includes a vertical foundation 12 that extends vertically upward from the ground F1 to surround the underfloor ventilation duct S1, and a floor plate 11 that is connected to the upper end of the vertical foundation 12 and is parallel to the ground F1. As shown in FIG. 1, the underfloor ventilation duct S1 is a space surrounded by the ground F1, the vertical foundation 12, and the floor plate 11, and extends horizontally. The floor 10 also includes other components such as a foundation, joists, and floor beams, but these are omitted in FIG. 1.

The vertical foundation 12 includes an inner surface 12A facing the underfloor ventilation duct S1 and an outer surface 12B facing the opposite side (outdoor air space side) to the inner surface 12A. The vertical foundation 12 is provided with a plurality of underfloor ventilation openings (first underfloor ventilation opening 10A, second underfloor ventilation opening 10B) that connect the underfloor ventilation duct S1 to the outdoor air space. The first underfloor ventilation opening 10A and the second underfloor ventilation opening 10B are both holes that penetrate the vertical foundation 12 in the thickness direction, with one end opening to the inner surface 12A (underfloor ventilation duct S1 side) and the other end opening to the outer surface 12B (outdoor air space side).

In the example of FIG. 1, the first underfloor ventilation opening 10A functions as an outlet for air W1 to flow out from the underfloor ventilation duct S1 to the outside air space, and the second underfloor ventilation opening 10B functions as an inlet for air W1 to flow from the outside air space into the underfloor ventilation duct S1, but this is not limited to this. For example, when the wind direction changes depending on the season, etc., the first underfloor ventilation opening 10A may function as an inlet for air W1 and the second underfloor ventilation opening 10B may function as an outlet for air W1. The number of underfloor ventilation openings is not particularly limited, and three or more may be provided.

The floorboard 11 includes a lower surface 11A facing the underfloor ventilation duct S1 and an upper surface 11B facing the opposite side to the lower surface 11A. The floorboard 11 is provided with an intake port 13 to which an intake duct 40 is attached. The intake port 13 is a hole that penetrates the floorboard 11 in the thickness direction, with one end opening to the lower surface 11A side (the underfloor ventilation duct S1 side) and the other end opening to the upper surface 11B side (the storage space S3 side of the shoe cabinet 30).

Figure 2 is a plan view of the shoe cabinet 30 seen from above, with the intake ports 13 indicated by dashed lines. As shown in Figure 2, in this embodiment, multiple intake ports 13 (e.g., two) are provided at intervals from each other in the surface direction of the exterior wall 20 (the longitudinal direction of the shoe cabinet 30). For this reason, multiple intake ducts 40 (e.g., two) are also provided to match the number of intake ports 13. Additionally, the intake ports 13 are circular holes when viewed from above, but are not limited to this shape.

As shown in FIG. 1, the exterior wall 20 is provided with an in-wall ventilation duct S2 for ventilation within the wall. The in-wall ventilation duct S2 extends in the surface direction of the exterior wall 20 (in the depth direction of the paper in FIG. 1) and in the vertical direction. As shown in FIG. 1, in this embodiment, an inlet 21 for introducing air W2 is provided at the bottom of the in-wall ventilation duct S2, and an outlet 22 for discharging air W2 is provided at the top of the in-wall ventilation duct S2. The flow rate (air volume) of air W2 in the in-wall ventilation duct S2 is smaller than the flow rate (air volume) of air W1 in the underfloor ventilation duct S1. Therefore, the wind pressure in the underfloor ventilation duct S1 is greater than the wind pressure in the in-wall ventilation duct S2. The inlet 21 and outlet 22 are not limited to the positions shown in FIG. 1, and may be upside down.

The exterior wall 20 extends vertically upward from a portion of the upper surface 11B of the floorboard 11 that is located above the first underfloor ventilation opening 10A. The exterior wall 20 is provided with an exhaust opening 24 that connects the storage space S3 of the shoe cabinet 30 to the in-wall ventilation passage S2. The exhaust opening 24 is a hole that penetrates the exterior wall 20 in the thickness direction, and an exhaust duct (not shown) is attached to it.

The shoe cabinet 30 is provided with a storage space S3 for footwear (e.g., boots 100, sandals 101, etc.) and is arranged on the floor 10. Specifically, the shoe cabinet 30 includes a bottom plate (not shown) arranged on the upper surface 11B of the floor board 11, a storage door 32 extending vertically upward from the bottom plate, a back plate (not shown) arranged along the inner surface 23 of the outer wall 20, a top plate 31 connecting the upper end of the storage door 32 to the upper end of the back plate, and a pair of side plates (not shown) arranged in the depth direction of the paper in FIG. 1 with the storage space S3 in between. As shown in FIG. 1, the storage door 32 is arranged on the opposite side of the outer wall 20 as viewed from the intake port 13. The storage space S3 is a rectangular parallelepiped space surrounded by the inner surfaces of the bottom plate, the storage door 32, the back plate, the top plate 31, and the side plates.

The storage door 32 is for opening and closing the storage space S3 from the indoor space (e.g., the entrance) side, and is provided on the opposite side of the exterior wall 20 with the storage space S3 in between. In this embodiment, the storage door 32 has an airtight structure, which prevents odors from leaking from the storage space S3 to the indoor space.

The shoe cabinet 30 further includes a number of shelves (first to fourth shelves 33 to 36) that are arranged at intervals in the vertical direction in the storage space S3. As shown in FIG. 1, the first to fourth shelves 33 to 36 are each arranged in a horizontal position, and include a front end (first to fourth front ends 33B to 36B) on the storage door 32 side and a rear end (first to fourth rear ends 33A to 36A) on the exterior wall 20 side.

Between the first to fourth front ends 33B to 36B of the storage space S3 and the inner surface of the storage door 32, there is a gap (front ventilation passage) that extends in the vertical direction and allows ventilation. As shown in FIG. 1, the gap between each front end and the inner surface of the storage door 32 becomes larger from bottom to top. In addition, between the first to fourth rear ends 33A to 36A of the storage space S3 and the back panel (not shown), there is also a gap (rear ventilation passage) that extends in the vertical direction and allows ventilation. The second to fourth shelf boards 34 to 36 are supported at predetermined positions in the vertical direction by a pair of side panels (not shown). In addition, in this embodiment, the second to fourth rear ends 34A to 36A are all claw portions that are folded back toward the lower level side.

An upper plate 37 is provided above the fourth shelf plate 36 in the storage space S3. As shown in FIG. 1, the upper plate 37 is provided with a gap between its front end and the inner surface of the storage door 32, and its rear end is fixed to the rear plate (not shown).

As shown in FIG. 1, the first to fourth shelves 33 to 36 are arranged such that their rear ends are closer to the exterior wall 20 from the lower level to the upper level. That is, the second rear end 34A is offset closer to the exterior wall 20 than the first rear end 33A, the third rear end 35A is offset closer to the exterior wall 20 than the second rear end 34A, and the fourth rear end 36A is offset closer to the exterior wall 20 than the third rear end 35A.

The storage space S3 is connected to the underfloor ventilation duct S1 via the intake port 13 and to the in-wall ventilation duct S2 via the exhaust port 24. Therefore, air W1 is taken in from the underfloor ventilation duct S1 into the storage space S3, and the inside of the shoe cabinet 30 is ventilated by the air W1 rising through the storage space S3. More specifically, because the pressure in the underfloor ventilation duct S1 is greater than the pressure in the storage space S3, the air W1 is pushed from the underfloor ventilation duct S1 into the storage space S3. Then, the air W1 that has risen to the vicinity of the top board 31 is exhausted through the exhaust port 24 to the in-wall ventilation duct S2, and is exhausted to the outside air space together with the air W2 flowing through the in-wall ventilation duct S2.

The first shelf 33, which is the lowest of the multiple shelves, is configured to guide the air W1 taken from the underfloor ventilation duct S1 into the storage space S3 to the area of the storage space S3 on the exterior wall 20 side. Specifically, the first shelf 33 has a first front end 33B fixed to a bottom plate (not shown), and a curved back surface (the surface facing the intake port 13) so that the gap between the bottom plate and the first front end 33B gradually widens from the first front end 33B toward the first rear end 33A.

The intake duct 40 is for taking in air W1 from the underfloor ventilation duct S1 to the storage space S3, and is attached to the intake port 13. As shown in FIG. 1, the intake duct 40 is provided with a first duct port 41 facing the first underfloor ventilation port 10A, and a second duct port 42 facing the second underfloor ventilation port 10B (the side opposite to the first duct port 41).

The first duct opening 41 and the second duct opening 42 are circular openings for taking in air W1 from the underfloor ventilation duct S1 into the intake duct 40, and face the underfloor ventilation duct S1. When air W1 is taken in from the first underfloor ventilation opening 10A, air W1 is taken in from the first duct opening 41 into the intake duct 40. On the other hand, when air W1 is taken in from the second underfloor ventilation opening 10B, air W1 is taken in from the second duct opening 42 into the intake duct 40.

The intake duct 40 includes an attachment portion 46 attached to the intake port 13, and is a branch duct that extends from the attachment portion 46 toward the first duct port 41 and the second duct port 42. The attachment portion 46 is a hollow cylindrical duct portion inserted into the hole of the intake port 13, and its upper end penetrates the bottom plate (not shown) of the shoe cabinet 30 and opens into the storage space S3.

The first duct opening 41 overlaps the first underfloor ventilation opening 10A in the vertical direction, and has a smaller vertical dimension than the first underfloor ventilation opening 10A. More specifically, the first duct opening 41 is within the height range of the first underfloor ventilation opening 10A, and the uppermost edge of the first duct opening 41 is at approximately the same height as the uppermost edge of the first underfloor ventilation opening 10A, while the lowermost edge of the first duct opening 41 is located above the lowermost edge of the first underfloor ventilation opening 10A. Similarly, the second duct opening 42 overlaps the second underfloor ventilation opening 10B in the vertical direction, and has a smaller vertical dimension than the second underfloor ventilation opening 10B. That is, the second duct opening 42 is within the height range of the second underfloor ventilation opening 10B, and the uppermost edge of the second duct opening 42 is at approximately the same height as the uppermost edge of the second underfloor ventilation opening 10B, while the lowermost edge of the second duct opening 42 is located above the lowermost edge of the second underfloor ventilation opening 10B.

The horizontal distance between the first duct opening 41 and the first underfloor ventilation opening 10A is determined so that a portion of the air W1 taken into the underfloor ventilation duct S1 from the first underfloor ventilation opening 10A is taken into the intake duct 40 from the first duct opening 41, and the remainder of the air W1 flows through the underfloor ventilation duct S1 without being taken into the intake duct 40. Similarly, the horizontal distance between the second duct opening 42 and the second underfloor ventilation opening 10B is determined so that a portion of the air W1 taken into the underfloor ventilation duct S1 from the second underfloor ventilation opening 10B is taken into the intake duct 40 from the second duct opening 42, and the remainder of the air W1 flows through the underfloor ventilation duct S1 without being taken into the intake duct 40.

Figure 3 is an enlarged view of the intake duct 40 near the first duct opening 41 and the second duct opening 42. The intake duct 40 includes a partition 43 that prevents air from passing from one of the first duct opening 41 and the second duct opening 42 to the other. As shown in Figure 3, the partition 43 is a wall provided between the first duct opening 41 and the second duct opening 42, and has a height H1 equal to or greater than the first duct opening 41 and the second duct opening 42.

More specifically, the partition 43 includes guides (first guide 44, second guide 45) that guide the air taken into the intake duct 40 upward toward the storage space S3 (FIG. 1). As shown in FIG. 3, the first guide 44 is a curved surface portion that extends in an arc from the lower edge of the first duct opening 41 toward the upper side (top 43A) and bulges convexly in the direction away from the first duct opening 41. The second guide 45 is provided symmetrically to the first guide 44, and is a curved surface portion that extends in an arc from the lower edge of the second duct opening 42 toward the upper side (top 43A) and bulges convexly in the direction away from the second duct opening 42. The first guide 44 and the second guide 45 are connected at the top 43A.

A first filter 41A is attached to the first duct opening 41, and a second filter 42A is attached to the second duct opening 42. The first filter 41A and the second filter 42A allow air to pass through while preventing the intrusion of insects, dust, etc. Note that these filters are not essential components of the present invention and may be omitted.

As described above, in the building 1 according to this embodiment, air W1 can be taken in from the underfloor ventilation duct S1 into the storage space S3. The air W1 is guided by the rear surface of the first shelf 33 to the area of the storage space S3 on the exterior wall 20 side, and is taken in into the area between the shelves while rising up the rear ventilation duct. After flowing to the front ends of the shelves, the air W1 rises up the front ventilation duct. The air W1 then collides with the inner surface of the top plate 31 and flows from front to rear in the upper area of the top plate 37.

In this way, after flowing over a wide area within the storage space S3, the air W1 is discharged through the exhaust port 24 into the in-wall ventilation passage S2. This allows the storage space S3 to be ventilated, and odors and moisture within the storage space S3 can be expelled to the outside air space through the in-wall ventilation passage S2. In this way, according to the building 1 of this embodiment, the ventilation passages in the floor 10 and the exterior wall 20 can be used to ventilate the shoe cabinet 30, so there is no need to install a ventilation fan within the shoe cabinet 30. Therefore, the footwear storage space is not narrowed by installing a ventilation fan, and the shoe cabinet 30 can be ventilated while maintaining a large storage space. Furthermore, since a ventilation fan is not used, power consumption can be reduced.

(Embodiment 2)
Next, a building 1A according to a second embodiment of the present invention will be described with reference to Fig. 4. The building 1A according to the second embodiment has a configuration similar to that of the building 1 according to the first embodiment and achieves the same effects, but differs in the configuration of the intake port. Only the differences from the first embodiment will be described below.

Figure 4 is a plan view of the shoe cabinet 30 seen from above, and corresponds to Figure 2. As in Figure 2, the intake port 13A is indicated by a dashed line in Figure 4. As shown in Figure 4, the intake port 13A in embodiment 2 has a rectangular shape in plan view extending in the surface direction of the exterior wall 20 (the longitudinal direction of the shoe cabinet 30). Although not shown, the shape of the mounting portion 46 (Figure 1) of the intake duct 40 is also a rectangular shape in plan view extending in the surface direction of the exterior wall 20 so that it can be mounted to the intake port 13A.

By adopting the above-mentioned shape of the intake 13A, the air W1 can be more efficiently taken in from the underfloor ventilation duct S1 to the storage space S3, thereby improving the ventilation efficiency of the storage space S3. Note that although only one intake 13A is provided in FIG. 4, multiple intakes 13A may be provided side by side.

(Other embodiments)
Here, other embodiments of the present invention will be described.

In the shoe cabinet 30, the second to fourth rear ends 34A to 36A are not limited to being all claw portions, and only some of the second to fourth rear ends 34A to 36A may be claw portions. Also, all of the second to fourth rear ends 34A to 36A do not have to be claw portions.

The number of duct openings in the intake duct 40 may be changed as appropriate depending on the number of underfloor ventilation openings, and may be three or more. In addition, it is not limited to the case where multiple duct openings are provided, and only one duct opening may be provided.

In the intake duct 40, the first duct opening 41 may be located outside the height range of the first underfloor ventilation opening 10A, and the second duct opening 42 may be located outside the height range of the second underfloor ventilation opening 10B.

The shapes of the first duct opening 41 and the second duct opening 42 are not limited to being circular, and may be, for example, rectangular. Also, the intake duct 40 may be omitted.

In the first embodiment, the intake port 13 is provided below the first shelf board 33, but this is not limited to the above. For example, the intake port 13 may be provided rearward (toward the outer wall 20) from the position shown in FIG. 1, and the air W1 may be directly blown out from the upper end opening of the intake duct 40 into the rear ventilation duct of the storage space S3. In this case, the first duct opening 41 and the first underfloor ventilation opening 10A may be prevented from coming close to each other by the following method. For example, the first underfloor ventilation opening 10A may be provided at a position shifted in the depth direction of the paper surface in FIG. 1 relative to the first duct opening 41. As another method, the positions of the first duct opening 41 and the second duct opening 42 may be left as they are in FIG. 1, and a connecting portion (not shown) connecting the mounting portion 46 to the first duct opening 41 and the second duct opening 42 may be provided along the underside 11A of the floor board 11. This allows air W1 to be blown directly into the rear ventilation duct of the storage space S3 while maintaining the horizontal distance between the first duct opening 41 and the first underfloor ventilation opening 10A.

In the storage space S3, the front ventilation passage (the gap between the front end of the shelf and the inner surface of the storage door 32) may be omitted. That is, when the storage door 32 is closed, the front end of the shelf may abut against the inner surface of the storage door 32. In this case, a slit may be formed in the front end portion of each shelf, and the air W1 may pass through the slit. This slit penetrates each shelf in the thickness direction and has a rectangular shape that is long in the longitudinal direction of the shoe cabinet 30. The opening area of the slit may expand from the bottom to the top.

The first to fourth rear ends 33A to 36A may abut against the inner surface 23 of the outer wall 20. In this case, a slit may be formed in the rear end portion of each shelf board, and the opening area of the slit may expand from the bottom to the top.

In the first embodiment, the first to fourth rear ends 33A to 36A are shifted rearward (toward the outer wall 20) from the lower mold to the upper mold, but this is not limited to the above. The horizontal positions of the first to fourth rear ends 33A to 36A may all be aligned.

The storage door 32 is not limited to having an airtight structure and may be, for example, a door with louvers.

In the first embodiment, a house is described as an example of a building, but the present invention can also be applied to buildings other than houses.

The embodiments disclosed herein are illustrative in all respects and should not be construed as limiting. The scope of the present invention is indicated by the claims rather than the above description, and is intended to include all modifications within the meaning and scope of the claims.
