Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deodorizing and sterilizing plate used for a wall material, a ceiling material, a floor material, etc. in a room where an odor is generated.

[0002]

2. Description of the Related Art In refrigerators / freezers, containers, etc.,
An odor is constantly generated from the stored material inside thereof, and in order to reduce the odor concentration, a method of forcibly expelling the odor or a method of using a deodorant such as activated carbon is adopted.

[0003]

However, these cannot prevent the adsorption of odors to the walls, ceilings, floors, etc. in the room or container, and the odors once adsorbed have a low odor concentration in the internal air. In that case, there is a problem that the odor is constantly left in the room because it is volatilized again.

Therefore, an object of the present invention, which was devised to solve the above-mentioned problems, is to be used as a wall material, a ceiling material, a floor material, etc. in a room where an odor is generated and to completely prevent the adsorption of the odor. It is to provide a deodorizing sterilization plate that can be used.

[0005]

In order to achieve the above object, the deodorizing and sterilizing plate according to the present invention forms a sheet facing the room or the like with a hollow fiber having one end closed and a myriad of micropores on the surface. While connecting the ozone supply means for introducing ozone into each of the hollow fibers to the open end of the hollow fibers constituting the sheet, attached a back plate forming a predetermined hollow chamber on the back side of the sheet, Further, the hollow chamber is connected with ozone suction means for discharging the ozone discharged from the sheet to the outside of the system.

[0006]

According to the above construction, the ozone supplied from the ozone supplying means is discharged so as to seep out to both sides of the sheet through the fine holes of the hollow fiber. Immediately after that, the ozone that has exuded is sucked and discharged from the hollow chamber of the back plate by the ozone suction means, and in particular, the ozone that has exuded to the inside of the chamber passes through the sheet and is sucked before being diffused. Thus, if the sheet is used as a wall material by facing the room, an ozone film having a predetermined thickness can be always formed on the surface of the sheet, that is, the wall surface.
The deodorizing action of ozone can completely prevent the adsorption of odors on the wall surface.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 is a sectional perspective view showing a deodorizing and sterilizing plate according to the present invention. In this deodorization sterilization plate 1, a back plate 4 is attached to a back surface side of a sheet 2 whose front surface faces the room, with a ventilation plate 3 having air permeability interposed therebetween. As shown in FIGS. 2 and 3, the sheet 2 is formed by weaving the hollow fibers 5 closed at one end in a lattice shape by a method such as heat fusion, adhesion, or sandwiching. The hollow fiber 5 has innumerable fine holes 6 on the entire surface portion thereof, and the open ends thereof are aligned with the upper end portion and the left end portion (viewed from the inside of the sheet) of the sheet 2.

Here, the hollow fiber 5 is a so-called straw-shaped fiber having a hollow inside. The hollow fiber 5 applied here is made of a polymer having a function as a separation membrane, and as the polymer material, those having a uniform porous membrane include polyethylene, polypropylene,
Polytetrafluoroethylene, polyester, polycarbonate, etc.
Examples include polyimide, polysulfone, and cellulose acetate. The polymer may be formed into a hollow fiber having a diameter of several mm or less, and may be referred to as a hollow fiber membrane. These microporous hollow fibers are also used as household water purifiers by producing pure water, enriching oxygen, separating hydrogen, artificial dialysis, and combining modularized ones with activated carbon.

At the open end of the hollow fiber 5, ozone supply means 7 for introducing ozone O _{3 of a} predetermined pressure into the hollow fiber 5 is connected. The ozone supply means 7 is an ozone generator 8
The ozone O ₃ having a predetermined pressure sent from the blower 9 is introduced into the hollow fiber 5 through the introduction pipe 10.

FIG. 4 shows the open end portion of the hollow fiber 5 in detail, as shown in the figure, all open ends are connected by a transparent or opaque supply tube 11. Therefore, the supply pipe 11 is bent at a right angle and downward at the upper left end of the seat 2. The supply pipe 11 (not shown) connects the hollow fiber 5 to the sealant 1
2 is airtightly attached, and the introduction pipe 10 is connected to one end of the supply pipe 11 located at the upper right end, and the other end of the supply pipe 11 located at the lower left end is closed.

Returning to FIG. 1, the back plate 4 has a hollow chamber 13 having a U-shaped cross section, which is open to the front of the ventilation plate 3.
To the hollow chamber 13, an ozone suction means 16 composed of a suction pump 14 and an ozone decomposition filter 15 is connected via a lead-out pipe 17. The ozone decomposition filter 15 is connected to the suction side of the suction pump 14, and the suction pump 1
The discharge side 4 is open to the outside. The sheet 2, the ventilation plate 3, and the back plate 4 are attached by firmly adhering them with an adhesive or bolting.

Next, the operation of the embodiment will be described.

Ozone O ₃ generated from the ozone generator 8 is adjusted to a predetermined pressure by the blower 9 and supplied into the hollow fiber 5 through the introduction pipe 10 and the supply pipe 11. The ozone O
_The minute ₃ oozes out to the outside little by little from the very small holes 6 as shown in FIG. Therefore, as shown in FIG. 5, ozone O ₃ oozes out from the front surface side (room side) and the back surface side (back plate 4 side) of the sheet 2, but immediately after this, the ozone O ₃ is sucked from the back surface side by the suction pump. It is quickly sucked and discharged by 14. In other words, ozone O oozing on the back side
After passing through the ventilation plate 3, ₃ is the hollow chamber 13 and the outlet pipe 17.
After that, it is decomposed by the ozone decomposition filter 15 and finally discharged from the suction pump 14 to the outside. Further, the ozone O ₃ on the front surface side is sucked at the portion to be diffused after oozing out, passes through the texture of the sheet 2 and wraps around to the back surface side, and is discharged to the outside through the route similar to the above.

As described above, on the front surface side of the sheet 2, the ozone O ₃ is always exuded and the surplus portion of the ozone O ₃ which is trying to diffuse is sucked in, so that the entire front surface side of the sheet 2 is absorbed. In addition, the ozone film F having a very thin film thickness can be formed.

The deodorizing and sterilizing plate 1 constructed as described above is used as a wall material, a ceiling material, a floor material, etc. when the surface side, that is, the sheet 2 side, is exposed to a room where odor is generated or remains. Such advantages arise.

That is, the entire surface of the seat 2 on the indoor side is completely covered with the thin ozone film F. Therefore, the odor touched by the seat 2 is deodorized by the deodorizing action of ozone O ₃ , and at the same time, the odorous substance to the sheet 2 is removed. Direct contact is completely prevented. Therefore, it is possible to completely prevent the odor from adsorbing to the wall surface, and also to prevent re-volatilization thereof, so that the room can be completely made odorless. In particular, when the odor concentration is normal, only the deodorizing and sterilizing plate 1 can be used, and when the odor concentration is relatively high, it can be used in combination with the forced diffusion device.

Further, since ozone O ₃ has a sterilizing effect, the deodorizing and sterilizing plate 1 is very effective even when it is used in a place such as a hospital where other bacteria are disliked. For example, by using it as a wall of a corridor or the like, the wall surface can be kept in a sterile condition at the same time, and at the same time, adhesion of bacteria to the wall surface can be prevented to completely prevent hospital infection.

Further, ozone O ₃ is toxic to the human body and therefore harmful to indoor workers at high concentrations, but since the ozone film F covering the wall surface is very thin and does not diffuse, this causes ozone O ₃ You can work safely without worrying about the harm.

As another advantage, when the supply pipe 11 is transparent, the internal state of the supply pipe 11 can be confirmed from the outside.

In this deodorizing and sterilizing plate 1, ozone O ₃
The film thickness of the ozone film F can be freely controlled by appropriately balancing the supply pressure and the suction pressure. Therefore, the ozone supply means 7 and the ozone suction means 16
By further providing a control circuit for performing pressure control with
The film thickness of the ozone film F and the ozone O ₃ diffusion amount can be optimally adjusted.

Next, in the modified embodiment shown in FIG.
A net 18 that replaces the ventilation plate 3 is interposed between the seat 2 and the back plate 4. The ventilation plate 3 enhances the rigidity of the indoor wall surface and prevents deformation of the net 18 by suction to achieve a flat wall surface. However, for example, when the wall surface does not need to be completely flat, such a net 18 is used. You may use. The net 18 may be a strong one made of metal or a relatively soft one made of plastic. Further, it is possible to directly attach the sheet 2 and the back plate 4 without using these inclusions.

There are various other possible modifications. For example, it is possible to use the back plate 4 as a frame and attach the sheets 2 to both sides of the frame and use it as a partition plate.
