Abstract

PURPOSE:To safely supply the air under a floor by opening a floor air supply hole at a floor panel under a storage warehouse, and forming an air supply hole at an opened housing provided at a wall of the warehouse under stairs. CONSTITUTION:A door 3 is mounted in an opening formed at part of a partition wall for dividing to a habitable room side and a storage warehouse R under stairs. A floor 4 of the warehouse R is set to a position higher than a height level of a floor panel 1 of a habitable room side. A floor air supply hole 1H for supplying the air under a floor is opened at the panel 1 of the warehouse R, and a level difference of the panel 1 and the floor 4 is so decided that the air under the floor can be supplied from the hole 1H and discharged from an air supply hole 6 opened at a lower housing 5 to the habitable room side. An opening housing 7 is integrally formed at the opening provided at the partition wall of the warehouse R. Thus, the air under the floor is supplied from the hole 1H to a space between the panel 1 and the floor 4, fed through the hole 6 of the housing 5, and supplied to inside of the room.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an underfloor air supply device for supplying air into a room from below a staircase.

[0002]

2. Description of the Related Art In order to effectively utilize the limited space of a house, the space under the stairs is often used as a storage. Air is supplied to the room from under the floor of the storage room under the stairs, and air is supplied from below the floor through the air supply holes formed in the riser of the stairs. Since this underfloor air supply does not make a hole in the outer wall, it is possible to reduce the number of labors required for rain wrapping and to supply air with the outer wall side opening completely closed, which is also advantageous in terms of crime prevention. When an air supply hole is provided in a conventional riser plate, a nose protrudes above the air supply hole to protect the aesthetics and the air supply surface.

[0003]

However, in recent years, there is an increasing need for consideration of elderly people in houses, and safety is required even on stairs. However, in the case where the kick plate is provided with the air supply hole as in the conventional case, a protruding nose is formed so as to protrude so as to protect the air supply hole, which is dangerous because it stumbles when ascending and descending stairs. Therefore, it is desirable to eliminate this nosing in order to improve the safety on the stairs.

An object of the present invention is to provide an underfloor air supply in a safe manner to provide underfloor air supply by providing a position of an air supply hole for underfloor air supply in a storage portion attached to a staircase.

[0005]

The present invention has been made in order to achieve the above-mentioned object, and the floor of the storage under the stairs is set higher than the floor panel on the living room side by an air supply height, A floor air supply hole is drilled in the floor panel below the storage, and an air supply hole is formed in the lower frame of the opening frame provided on the wall of the storage under the stairs.
The gist is that air is supplied to the room from below the floor through the underfloor air supply hole of the storage under the stairs.

[0006]

[Operation] The floor of the storage under the stairs is set higher than the floor panel on the living room side so that air can be supplied, and the lower frame of the opening frame of the storage has an air supply hole communicating with the space between the storage floor and the floor panel. Since the floor air supply hole of the floor panel below the storage is provided, it is possible to supply air from the underfloor to the room without changing the staircase structure and the like, while ensuring a safe ascent and descent of the stairs.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The underfloor air supply system of the present invention will be described below with reference to the illustrated embodiments. In the figure, reference numeral 1 denotes a floor panel on the first floor of a corridor or a living room. Flooring carpets, tatami mats, etc. are laid on the floor panel 1 as necessary, and the living room and the storage R under the stairs are separated from each other. A door 3 (which is divided by the wall 2 and has a partition wall 2 for opening and closing articles in and out of the storage R is opened and closed as necessary. Or a sliding door) is attached, so that the staircase storage and the living room side are completely separated.

The floor 4 of the staircase storage R is a floor panel 1 on the room side.
It is set higher than the height level of. In this, the floor panel 1 in the staircase storage is provided with a floor air supply hole 1H having a required opening area for underfloor air supply, and the air under the floor is supplied from the floor air supply hole 1H to open to the lower frame 5. The level difference between the floor panel 1 and the floor 4 is determined so that an appropriate space is provided as a passage for the underfloor air so that the air can be discharged to the room side through the air supply hole 6.

In the opening provided in the partition wall 2 of the staircase storage R, an upper frame, a lower frame and a side frame are arranged along the four circumferences thereof to integrally form the opening frame 7. As shown in FIG. 1, the thickness of the lower frame 5 of the opening frame 7 is such that there is a difference in height between the floor panel 1 and the floor 4, and the lower frame 5 is provided with an air supply hole 6 having a required opening area. It is formed in a slit shape or the like, and a fixed type or variable type gallery 8 is provided in the air supply hole 6 as needed. In addition, a net may be installed in the floor air supply hole 1H provided in the floor panel 1 so that harmful insects, dust, and the like that enter under the floor do not enter the living room.

The air under the floor is supplied to the floor panel 1 through the floor air supply hole 1H.
・ Introduced into the space A between the floors 4, and the air supply holes 6 of the lower frame 5
The air is supplied to the indoor side through the above, but this is done when the air is naturally ventilated, and in the space A between the floor panel and the floor or by the fan attached to the floor panel.

The staircase storage R has a different shape and storage area depending on the type of staircase, that is, a straight staircase, a folded staircase, and the installation position of the opening changes. However, the floor 4 of the staircase storage R has a floor panel 1. The arrangement is the same in that it is arranged at a position higher by a predetermined height than the above, and air is supplied into the room from under the floor through the lower frame.

[0012]

According to the present invention, the underfloor air supply device is installed with the floor of the storage space under the stairs set higher than the floor panel on the side of the room by the height at which air can be supplied, and a floor air supply hole is formed in the floor panel below the storage space. In addition, since the air supply hole is formed in the lower frame of the opening frame provided on the wall of the storage under the stairs, it is possible to supply air from under the floor under the stairs to the room without changing the riser plate of the stairs. . Further, by integrating the air supply hole with the opening frame, there is an advantage that the appearance is not impaired and the construction work can be reduced.
