Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a door or a fitting such as a fusuma which accommodates straw grass, and belongs to the industrial field of manufacturing or handling fittings.

(Prior Art) Conventionally, a fitting in which a core of the fitting is filled with a heat insulating material or a sound insulating material is known, and it is said that the fitting has a characteristic of soundproofing or flame retardancy.

(Problems to be solved by the invention) Conventionally, the maximum NOx limit is set to 0.04 ppm, for example, in exhaust gas regulations of automobiles or industrial exhaust regulations, but a means for actively removing NOx from the atmosphere has been established. Since it has not been tampered with, it is not uncommon for NOx to exceed 0.06 ppm, which is higher than the above-mentioned standard, in the vicinity of highways or places with industrial exhaust. Further, it has been reported that an increase in NOx in the living environment is related to an increase in the incidence of lung cancer, gastric cancer and the like. Therefore, it is said that there is a possibility that the survival of human beings will be seriously affected unless the generated NOx is adsorbed and removed or is made pollution-free together with legal regulations for reducing the generation of NOx.

(Means for Solving Problems) Therefore, this device was researched and developed for the purpose of improving the living environment of individuals, in addition to the legal means for controlling the concentration of NOx generation sources.

That is, the present invention focuses on the denitrification property of strawberries, and by effectively using this, NOx in a room, which is a living space, is improved.
Is intended to be reduced.

This invention constructs a fitting having a NOx removing function by constructing a ventilation part in a part or all of the front and back members stretched on a four-circle frame material at a predetermined interval and accommodating strawberries in the space between the front and back members. did. As the front and back members in the above, for example, fusuma paper, wood board, synthetic resin board or metal board is used. As the air-permeable portion, a material having air-permeability such as fusuma paper is used, or the air-permeable portion is formed by means such as providing a large number of minute holes on the front and back members or arranging slits in parallel.
Next, as for the strawberries, packaged strawberries which are obtained by wrapping shredded or crushed pieces of strawberries in a breathable material (for example, woven fabric or non-woven fabric) are used, but the collected length can also be used as it is.

Conventionally, a molded article of fibers (for example, a felt shape) is used as a heat insulating material or a sound insulating material, but it is also possible to mix strawberries into such a molded article.

Strawberry is effective for removing NOx or adsorptive decomposition,
Sound insulation and heat insulation effects can also be expected.

(Effect of the Invention) In this invention, since the ventilating portion is provided in all or a part of the front and back members stretched at a predetermined interval, and the strawberries are housed between the front and back members to construct the fitting, the interior of the fitting is passed. As a result, the NOx concentration in the indoor air can be reduced.

(Embodiment 1) An embodiment of the present invention will be described with reference to FIGS. 1 and 2.

That is, the stuffed strawberries 1 shredded to 10 mm to 50 mm are wrapped with the nonwoven fabric 2 to form the stuffed strawberries 3. On the other hand, breathable front and back fusuma papers 5 and 5a are stretched on the fitting frame 4, and the packaging straws 3 are accommodated between the lattices 6 to complete the fusuma 7 of the present invention.

According to the above-mentioned embodiment, since the front and back fusuma paper with air permeability is used, NOx is removed from the circulating air inside and outside the fusuma and the NOx concentration in the indoor air can be reduced without performing processing such as perforation. You can

(Example 2) The example shown in Fig. 3 relates to a wooden door.

That is, the front and back wood boards 9 and 9a are stretched on the door frame 8, the wrapping straw 3 is accommodated in the space between the front and back wood boards 9 and 9a, and the ventilation slits 10 and 11 are provided in the upper and lower parts of the back wood board. Wooden door 1
Completed 2.

According to the above, a part of the room air flows from the slit 10 to the door 1
By entering 2 and exiting the room from slit 11,
The door becomes a part of the counter flow path, which enables efficient denitrification.

(Example of use) Next, regarding NOx treatment when the fusuma of this invention is used,
explain.

The sliding doors 7 are built in the front surface of the push-in box 13, and the straw board 16 is laid on the partition plate 14 of the push-in box 13 via the coffin 15. It is more effective to attach the strawberries 16 to the upper and lower surfaces of the push-in closet and to the inner wall of the side surface.

The strawberry grass board 16 is a paperboard that is pressure-molded with strawberry grass fibers, and is in the form of cardboard.

(Effect of the Invention) According to the present invention, the air and the strawberry are brought into contact with each other through the ventilation portions provided on the front and back members, and NOx contained in the air is adsorbed or decomposed to automatically denitrify. The effect of reducing the NOx concentration in the indoor air is obtained.
