DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fitting which is installed in an opening / closing section of a storage section such as an entrance and a closet in a room.

[0002]

2. Description of the Related Art Building materials, wallpaper and wallpaper adhesives, paints, fittings, furniture and the like that constitute a current building contain volatile organic compounds such as formaldehyde, toluene, and xylene. Most of them disperse naturally.
In addition, the current building is equipped with cooling and heating and air conditioning functions, so the number of ventilations is small and the indoor confidentiality is high,
There is almost no natural circulation of indoor and outdoor air.

[0003]

As a result, the occupants are exposed to formaldehyde, volatile organic compounds, and the like, which are radiated from the building materials and filled in the room, so that the mucous membranes such as eyes and nose are simply stimulated. Not only do they fall into the so-called "sick house syndrome", which has an adverse effect on the body,
There were issues that had to be solved.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in consideration of the problem that a harmful substance is filled in a room based on the above-mentioned conventional technology. By installing a fitting between the front and back plates that has an air-permeable adsorbent with a porous adsorbent integrated with it, the porous adsorbent naturally adsorbs harmful substances and does not desorb it Thus, the above problem is solved.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a front view of a fitting, and FIG.
It is an enlarged view of the XX cross section. A pair of front and back plates 2 and 3 are provided on an outer frame 1 of a fitting to be installed at an opening and closing portion of a storage unit such as a doorway and a closet in a room, and slit-shaped ventilation portions 4, 4a. 5a are penetrated, and are arranged alternately on the front and back sides such that the ventilation portions 5, 5a... Of the other back plate 3 are located between the ventilation portions 4, 4a. are doing. Plate-like having air permeability between the front and back plates 2, 3;
A sheet-shaped adsorbent 6 is sandwiched, and the adsorbent 6 is formed by sandwiching a porous adsorbent 8, 8a... Made of powdered ceramic char between the air-permeable sheets 7, 7a on the front and back sides. I have.
Specifically, a plurality of accommodation recesses 9, 9a... Are formed in one breathable sheet 7 and the porous adsorbents 8, 8a. Are sandwiched between the porous sheets 7, 7a, and the porous adsorbents 8, 8a are integrated with the adsorbent 6. Also, since the adsorbent 6 is thin, the outer frame 1 is formed firmly to secure the strength, and the outer peripheral portions of the front and back plates 2 and 3 are fitted into the grooves formed on the inner surfaces of the vertical and horizontal frames of the outer frame 1. The front and back plates 2 and 3 are incorporated into the outer frame 1 and the adsorbent 6 is interposed between the front and back plates 2 and 3.
Is pinched.

If the front and back plates 2 and 3 are made of a paulownia plate having high moisture absorption and release properties, it is possible to finely adjust the indoor humidity. , 5, 5a... In the above embodiment are slit-shaped, but are not limited to such a form, and may be, for example, simple circular holes. The adsorbent 6 sandwiches the porous adsorbents 8, 8a,... Between the air permeable sheets 7, 7a, but is not limited to such a form. It may be a mixture of a porous adsorbent. One example is a gas-permeable sheet material described in JP-A-2000-96408, which is formed into a plate by mixing a resin, a fiber such as felt fiber and bamboo wool, and carbon particles.
The porous adsorbents 8, 8a,... Are made of ceramic charcoal, but are not limited to such materials. For example, they are porous materials having countless small holes such as charcoal, bamboo charcoal, activated carbon, and the like. Should be long-lasting. The porous adsorbents 8, 8a,... Are powdery, but may be lump-shaped, although not shown.

Next, the operation of the fitting according to the present invention will be described. In the process of passing through the adsorbent 6, the pores in the porous adsorbents 8, 8a,... Cause capillaries in the small holes, and formaldehyde and volatile organic compounds are taken into the small holes and adsorbed on the inner surfaces of the small holes. When room air moves between the rooms through the ventilation parts 4, 4a, 5, 5a, and the adsorbent 6, the air is meandered between the ventilation parts 4, 4a, 5, 5a, and the adsorbent 6 is long. They are in contact.

[0008]

According to the present invention, the outer frame 1 has the front and back plates 2,
3 as well as the ventilation portions 4, 4a on the front and back plates 2, 3.
, 5 and 5a are penetrated, and an adsorbent 6 having air permeability and an integrated porous adsorbent 8, 8a is sandwiched between the front and back plates 2 and 3, so that an air cleaner, ozone Since the harmful substances filled in the room can be removed without separately installing a device such as a deodorizer, the small living space can be effectively used without deteriorating the aesthetics of the room. Also, the ventilation parts 4, 4a ... 5,
5a are formed so as to be alternately positioned on the front and back sides, so that the air passing between the front and back plates 2 and 3 is in contact with the adsorbent 6 for a long time, so that it is possible to improve the adsorption efficiency and so on. The effect is enormous.
