Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a room equipped with sanitary equipment such as toilet equipment, shower equipment, bath equipment, or washbasin equipment.

[0002]

2. Description of the Related Art In a room equipped with sanitary facilities such as a bath, a toilet, a shower, and a washroom, due to its nature, the humidity is strong, waste is discharged, and it becomes airtight. Easy to remain. Further, it has been pointed out that harmful organic compounds such as highly toxic trihalomethane produced by the reaction of residual pesticide and chlorine are volatilized from mist-like warm water in a bath or shower using tap water.

As a means to deal with such problems,
There are known sanitary facilities having a photocatalytic functional layer formed on the surface thereof or building materials such as tiles. The photocatalyst functional layer is a metal oxide such as titanium oxide (TiO ₂ ) whose electronic state is excited by ultraviolet rays to perform an oxidation / reduction action, that is, a so-called photocatalytic semiconductor is fixed on the surface of a device by baking or the like. This photocatalytic semiconductor decomposes harmful organic compounds that cause stains and odors to adhere.

However, since the room in which the sanitary facilities are arranged often has a smaller window than a general living room, the photocatalytic effect using sunlight as an ultraviolet light source cannot be expected so much.
In addition, when the photocatalytic functional layer is formed on sanitary equipment or building materials, the UV radiator is installed independently of the photocatalytic functional layer, so the distance between the photocatalytic functional layer and the ultraviolet light source increases, and the UV irradiation is performed. ineffective. In addition, especially in the case where the room space is integrally provided, such as a toilet unit or a bath unit, the airtightness is high and the tendency of contamination and odor is strong.

In order to improve this situation, it is conceivable that the photocatalytic semiconductor is carried at a high density on a wall, a ceiling or the like to form irregularities to increase the surface area. However, according to this method, organic compounds and inorganic dust are likely to adhere to the unevenness of the finished surface, and stains that cannot be processed by the photocatalytic function are accumulated.
Further, it takes a great deal of effort to remove the dirt adhering to the surface of the building material by cleaning, and the members cannot be easily replaced.

[0006]

DISCLOSURE OF THE INVENTION The present invention efficiently removes harmful organic compounds that cause odors and stains and bad odors in a room (including the internal space of a unit) equipped with sanitary equipment that easily becomes dirty. It is an object of the present invention to provide a room which is disassembled to maintain a clean and comfortable environment and in which the sanitary equipment and building materials are not easily contaminated with dirt.

[0007]

[Means for Solving the Problems] Regarding a room in which sanitary facilities are arranged, a photocatalytic functional layer is formed on the surface of a member (building material, equipment) exposed to the room space, while an ultraviolet radiator is arranged in the room. Then, the photocatalytic functional layer is excited and activated by the ultraviolet rays of the ultraviolet radiator.

The photocatalytic semiconductor forming the photocatalytic functional layer is
TiO ₂ , ZnO, SrTiO ₃ , CdS, CdO, C
aP, InP, In ₂ O ₃ , CaAs, BaTiO ₃ ,
K ₂ NbO ₃ , Fe ₂ O ₃ , Ta ₂ O ₅ , WO ₃ SaO
₂ Bi ₂ O ₃ , NiO, Cu ₂ O, SiC, SiO ₂ ,
MoS _2, MoS _3, InPb, a RuO _2, CeO _2, TiO ₂ have been sold in the state of trade name "ST-01", "ST-31" (Ishihara Sangyo Kaisha, Ltd.) as a sol. The particle size of TiO _{2 in} the sol is 0.01 μm to 0.07 μm.

The wavelength of the ultraviolet rays for exciting the photocatalytic functional layer can be adjusted depending on the composition such that the wavelength varies depending on the photocatalytic semiconductor used.
In addition, Pt, Ag, R for supplementing functions such as mold prevention and sterilization.
uO ₂ , Nb, Cu, Sn, NiO or the like may be used as an additive.

The sanitary facilities are for baths, showers, toilets, washbasins and the like. As well known, these may be integrally formed with the room space as a unit. UV radiators include fluorescent tubes, black lights, mercury tubes, arc tubes,
Like an electron syncron tube, it emits energy (mostly power) from the outside to emit light, and it emits spontaneous energy by consuming internal energy, and emits spontaneous energy. It is a phosphorescent ultraviolet radiator that emits light. Spontaneous UV radiators utilize radiative decay of radium and promethium, and currently use refined rock powder containing such components.
It is not necessary to externally supply energy to the spontaneous UV radiator.

Luminova (trade name: Nemoto Special Chemical Co., Ltd.) and “Kiplus” (trade name: Next Eye Co., Ltd.) are commercially available as phosphorescent ultraviolet radiators. These are mainly composed of strontium aluminate (SrAl ₂ O ₄ ) containing components such as high-purity alumina, strontium carbonate, europium and dysprosium. The maximum point of the absorption spectrum is at 360 nanometers, and the particle size is 20 μm to 50 μm. Each of the ultraviolet radiators used in the present invention needs to have an ultraviolet region (at least a wavelength range of 180 nm to 400 nm) which is an absorption region of a photocatalytic semiconductor in its emission spectrum.

Any of the following configurations can be adopted. It is equipped with sanitary equipment and an ultraviolet radiator provided with a photocatalytic functional layer in close proximity. As a form in which the photocatalytic functional layer is provided in close proximity, the photocatalytic functional layer is directly carried on the surface of the ultraviolet radiator, the photocatalytic functional layer is formed on the outer surface of the outer cover attached to the ultraviolet radiator, There is a structure in which a photocatalytic functional layer is carried on the reflecting surface of an attached reflector. By thus supporting the photocatalyst functional layer directly on the UV radiator or on an accompanying member such as a cover, the photocatalyst functional layer and the UV radiator can be brought close to each other, and the efficiency of UV irradiation can be increased to improve hygiene equipment and room interior. It can efficiently decompose dirt, malodor and harmful organic compounds.

Further, the outer cover may be in the form of a louver in which a plurality of vanes having photocatalytic functional layers are arranged side by side on the front and back. Since the blades are spaced apart and arranged so as to be inclined, the air flowing behind the outer cover passes through the gap between the blades due to the effect of heat generated by the ultraviolet radiator placed behind them. Then, since it circulates in the room, the chances of contact between the photocatalytic function layer and harmful organic compounds floating in the air are increased, and the photocatalytic function is enhanced. Further, the ultraviolet light emitted from the ultraviolet radiator is inclined and is repeatedly reflected between the blade plates in a partially superposed state, so that the efficiency of ultraviolet light irradiation is improved.

The photocatalyst functional layer formed on the outer or bar is not formed on the entire surface of the cover, but is formed with a space between the regions of the photocatalyst functional layer like a stripe pattern. In some cases, the ultraviolet rays of the ultraviolet radiator are directly emitted into the room. The photocatalyst functional layer formed on the surface of the member (building material, equipment) exposed in the room space is activated by the weak ultraviolet rays that have passed through the outer cover that has the photocatalyst functional layer on the surface, and can exert the photocatalyst functional layer, but the ultraviolet radiation When the ultraviolet rays of the body are directly radiated into the room through the space between the regions, the photocatalytic function layer formed on the surface of the member (building material, equipment) exposed in the room space is fully activated and exhibits a high photocatalytic function. .

It is desirable that the UV radiator is a spontaneous UV radiator or a light-storing UV radiator because the activity of the photocatalytic functional layer is maintained even when the light is turned off or a power failure occurs. The UV radiator may be a spontaneous type, a luminous type, or a mixture of these and another type. It is desirable to support the photocatalytic semiconductor with a porous laminated structure using frit, beads, glass wool, etc. because the surface area of the photocatalytic functional layer exposed to ultraviolet rays becomes large. An ultraviolet radiator often serves as a lighting device like a fluorescent tube.

An ultraviolet radiator that also serves as a lighting fixture and an ultraviolet radiator that is a black light are arranged so that the black light is turned on when the lighting fixture is turned off. In this way, even if there is no person in the room and the lighting equipment is turned off, the photocatalytic function is maintained by the ultraviolet rays emitted by the black light. In this case, since there are no people inside the room, it is possible to enhance the ultraviolet radiation of the black light and enhance the photocatalytic function.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT FIG. 1 shows a washstand unit (room) in which a washstand 3 and an ultraviolet radiator 1 (a, b) provided with a photocatalytic functional layer in close proximity are installed. The room is made by slightly recessing the left and right sides of the front center wall, and the tip edge of the washbasin 3 is arranged in contact with the front center wall. That is,
There is a gap between the front left and right walls and the leading edge of the washbasin 3.

In the concave portion on the right side of the front surface, an ultraviolet radiator 1a, that is, a fluorescent tube 5 (another type ultraviolet radiator) is embedded in a wall, and an outer cover 4a stretched so as to be flush with the wall. It is hidden. The fluorescent tube 5 is used for an ordinary fluorescent lamp, and it is well known that its emission spectrum has an ultraviolet region effective for exciting a photocatalytic semiconductor.

The recess on the left side of the front face is provided with an outer cover 4b in which an ultraviolet radiator 1b having a fluorescent tube 5 arranged in parallel and a plurality of blades 17 are arranged in parallel in a vertical direction in a louver shape ( (Figure 6). A reflection plate 16 is attached to the wall 15 of this portion, and there is a space between the reflection plate 16 and the outer cover 4b, and this space is open at the upper side and the lower side. Further, each vane plate 17 is tilted around a horizontal axis and has a gap between each vane plate 17. The fluorescent tube 5 is located between the reflection plate 16 and the cover 4b. In addition, cover 4 (a,
The shape of b) is changed by the two types of covers 4 (a,
This is for the purpose of explaining b) at the same time, and in practice, it is often unified.

The vane plates 17 constituting the outer cover 4a and the outer cover 4b are composed of a substrate 6 of a polymer organic resin plate having a high transparency to ultraviolet rays such as a transparent glass plate or polycarbonate and a photocatalytic function layer 7 on the surface thereof. Configured (Figure 2). Although the glass plate is soda glass, borosilicate glass, quartz glass, or the like, which is more transparent with respect to ultraviolet rays, is used if the cost is affordable. As the transparent synthetic resin plate, a plate having ultraviolet transparency such as polycarbonate is used. In the case of the vane 17, photocatalytic functional layers are provided on the front and back.

The photocatalyst functional layer 7 is coated with a photocatalyst semiconductor and then baked, for example, by a known method (eg,
Japanese Unexamined Patent Publication No. 5-309267). In addition,
When the fluorescent tube 5 is used as a lighting fixture, a room equipped with sanitary facilities does not require the illuminance of a general living room,
The transparency of the cover 4 (a, b) must be secured to some extent. For this reason, for example, a method of coating the sol of TiO ₂ thinly to form the photocatalyst semiconductor layer 7 in the form of a transparent thin film, or forming the photocatalyst functional layer 7 on the surface of the substrate 6 in the form of stripes or lattices is adopted. To be done.

As shown in FIG. 3, the photocatalytic functional layer 7 has a porous laminated structure in which transparent particles 8 such as glass balloons and glass fibers having a high ultraviolet transmission performance are laminated with respect to ultraviolet rays. It is also possible to have a structure in which 9 is supported. By doing so, the surface area of the photocatalytic functional layer exposed to ultraviolet rays becomes very large, and the photocatalytic function is increased. The material of the balloon or fiber is not limited to glass, but may be an organic polymer resin such as polycarbonate that has a high UV transmission performance. The surface of the cover 4 (a, b) may be mixed with spontaneous or luminous UV radiators. In this way, the spontaneous or light-accumulation type ultraviolet radiator maintains the activity of the photocatalytic functional layer for a long time even after the fluorescent tube 5 is turned off.
It also functions as a night light.

The photocatalytic functional layer 7 formed on the cover 4 (a, b) can be formed by disposing the layer 10 of the light-accumulating ultraviolet radiator between the surface of the substrate 6 and the photocatalytic semiconductor layer.
The layer 10 is formed by spray-coating "Luminova" (trade name) and then baking it to a thickness of 100 mg / cm ² . If the layer 10 is made thick, the amount of ultraviolet radiation that is maintained after the fluorescent tube 5 is turned off is large, and the mechanical strength of the layer 10 is large, but the transparency is deteriorated or the fluorescent tube 5 is emitted to the outside. The amount of UV light that is generated is reduced.

In addition to the case where the coating is provided on the entire surface of the substrate 6, the coating may be provided in a stripe pattern or a grid pattern in order to increase the amount of ultraviolet rays emitted from the fluorescent tube 5 to the outside. Further, the layer 10 of the phosphorescent ultraviolet radiator may be provided on the back surface side. As shown in FIG. 5, the phosphorescent ultraviolet radiator may not be layered, but may be mixed into the inside of the substrate 6 as fine particles.

Since the ultraviolet rays are radiated from the phosphorescent type ultraviolet radiator even after the fluorescent tube 5 is extinguished, the photocatalytic function-equipped ultraviolet ray radiator 1 and the photocatalytic function provided with the phosphorescent type ultraviolet radiator are maintained as described above. The duration depends on the quality of the phosphorescent ultraviolet radiator and the manufacturing method of the photocatalytic functional layer, but when "luminova" is used, it is 15 hours or more, and is usually longer than the time until the fluorescent tube 5 is next turned on. long.

According to the above structure, the illumination effect of the fluorescent tubes 5 arranged on both sides in front of the washbasin 3 and the photocatalytic function layer 7 arranged in the vicinity of the fluorescent tubes 5 are the ultraviolet rays irradiated from the fluorescent tubes 5. Since the organic compounds in the air that are excited by and are brought into contact with this are efficiently decomposed, the environment of the wash space can be maintained comfortably.

Further, since there is a gap between the front edge of the wash basin 3 and the walls on both the left and right sides, even if the room is hermetically closed, the room air is removed from the floor by the heat generated by the fluorescent tube 5. It is easy to circulate through this gap to the ceiling. As a result, the organic compounds floating in the air often come into contact with the photocatalytic function layer 7 of the cover 4 (a, b), and the photocatalytic effect is enhanced.
Further, it is possible to brightly illuminate the lower portion of the wash basin 3 which is apt to become dirty due to dust and dirt.

Particularly in the case of the wall on the left side, the circulating air enters the inside of the louver-shaped cover 4b (FIG. 6) and escapes from the gap between the vane plates 17 so that the photocatalytic functional layer 7 has a chance to come into contact therewith. Many. In addition, since the ultraviolet ray from the fluorescent tube 5 is repeatedly reflected between the surfaces of the blade plate 17, the rate of effectively utilizing the ultraviolet ray is high.

Reference numeral 14 is a black light which is turned on when the lighting in the room, that is, the fluorescent tube 5 is turned off. When there is no person in the room and the fluorescent tube 5 is not turned on, the photocatalytic function is maintained by turning on the black light 14. It is possible to strongly irradiate the black light 14 with ultraviolet rays effective for the photocatalytic function layer 7 to enhance the deodorizing effect and the like when no one is present.

FIG. 7 shows a toilet space in which a UV radiator 1 having a photocatalytic function layer is installed on the ceiling, and FIG. 8 is a UV space radiator 1 having a photocatalytic function layer is installed on the ceiling. Shows the bus space created.

The ultraviolet radiator 1 provided with the photocatalyst functional layer in close proximity is provided on the ceiling, and in this embodiment, members exposed inside the room (equipment such as toilet equipment and walls, ceiling) , A building material constituting the floor) or a part thereof has a photocatalytic functional layer formed thereon. By doing so, the ultraviolet radiator 1 provided with the photocatalytic functional layer in close proximity thereto
Can illuminate the entire room more uniformly than the one installed on the wall surface, and the photocatalytic functional layer having a large area inside the room is activated by the ultraviolet rays emitted from the room so that the deodorizing efficiency is good. In addition, it is easy to remove the dirt attached to the wall surface.
Ultraviolet radiator 1 having these photocatalytic functional layers in close proximity
Since the configuration of is almost the same as that of the one installed on the right wall surface of the washroom, detailed description will be omitted. The ultraviolet radiator in this case may be an ordinary fluorescent tube having no photocatalytic functional layer in close proximity thereto, or a photocatalytic functional layer provided on the surface of the outer cover with stripes or the like at intervals. It may be.

FIG. 9 shows an example of the ultraviolet radiator 1 having the photocatalytic functional layer adjacent to the outer cover 4 which is not a part of a wall or a ceiling but a cover of an ordinary lighting fixture.
The ultraviolet radiator 1 having this photocatalytic functional layer in close proximity is
Near the mirror in the washroom or in the washroom, shower space,
It is installed on the wall or ceiling of the bath space, toilet space, etc.

In the ultraviolet radiator 1 having the photocatalyst functional layer adjacent thereto shown in FIG. 9, the base 6 molded into a substantially semicircular cross section.
The outer cover 4 is formed by providing the layer 10 of the phosphorescent ultraviolet radiator on the surface of the above, and further providing the photocatalytic function layer 7 on the surface thereof. The shape of the outer cover 4 is not limited to that shown in the figure. Alternatively, a small piece of the phosphorescent ultraviolet radiator may be mixed and molded into the material of the substrate 6 that constitutes the outer cover 4. The material or forming method of the outer cover 4, the layer 10 of the phosphorescent ultraviolet radiator and the photocatalytic functional layer 7 is the same as that of the embodiment shown in FIGS. 1 to 8.

FIG. 10 shows an ultraviolet radiator 1 having a photocatalytic function layer having a photocatalytic function in proximity to the fluorescent tube 5 itself. As shown in FIG. 11, the fluorescent tube 5 has a glass tube as a base and has a fluorescent agent layer 11 on the inner surface thereof, and a phosphorescent material formed between the fluorescent agent layer 11 and the fluorescent tube 5 by "luminova" (trade name). Type UV radiator layer 10, further comprising:
On the outer surface of the fluorescent tube 5, there is a photocatalytic semiconductor layer 7 formed of "ST-01" (trade name).

In FIG. 12, a layer 10 of a phosphorescent ultraviolet radiator is formed on the outer surface of the fluorescent tube 5, and a photocatalytic functional layer 7 is further formed on the surface thereof. As a method for forming the layer 10 of the phosphorescent ultraviolet radiator and the photocatalytic function layer 7 on the surface of the fluorescent tube 5, a known means of performing coating by spraying or dipping and then baking is used. Layer 10 of phosphorescent ultraviolet radiator
Has a thickness of 100 mg / cm 2, and the photocatalytic functional layer 7 has a thickness of
It is 1 μm to 40 μm.

When the fluorescent tube 5 is turned on, the fluorescent agent layer 11 is excited by the ultraviolet rays of the glow discharge to emit light, and the layer 10 of the light-accumulation type ultraviolet radiator is such that the ultraviolet ray or the fluorescent agent layer 11 that passes through the fluorescent agent layer 11 is It is excited by the emitted ultraviolet light and accumulates luminescent energy. At the same time, the photocatalytic functional layer 7 on the outer surface of the fluorescent tube 5
Ultraviolet rays also reach, and the photocatalytic function is exerted. When the fluorescent tube 5 is turned off, the ultraviolet rays due to the glow discharge are extinguished, but instead, the layer 10 of the light storing type ultraviolet radiator emits the energy accumulated and the photocatalytic function is maintained.

In FIG. 13, a region 12 having a constant area in which a photocatalytic semiconductor layer is formed on the ultraviolet radiator 1 is formed on the ceiling of the toilet space, and a black light 14 which emits strong ultraviolet rays is arranged in this region 12. . The black light 14 for irradiating ultraviolet rays is housed in a box 13 provided on a wall or a ceiling, illuminates the area 12 with directivity so as not to be seen by human eyes, and exerts a photocatalytic function.

The photocatalytic function layer in the region 12 has a wide contact area with irregularities and gaps, and a highly efficient photocatalytic function can be obtained by irradiating strong ultraviolet rays. FIG. 14 shows a reflector 16 of the lighting equipment.
The photocatalyst functional layer 7 is formed on the reflective surface of ′. Also in this example, since the fluorescent tube 5 and the reflecting plate 16 'are close to each other, the ultraviolet irradiation efficiency is good and a high photocatalytic function can be obtained.

[0039]

The photocatalytic function decomposes harmful organic compounds such as dirt and foul odors in a room equipped with sanitary facilities that tend to become dirty, and reduces the amount of organic compounds floating in the air. This makes it easier to remove dirt adhering to the inner surface and keeps the room clean and comfortable. When the photocatalyst functional layer and the UV radiator are arranged close to each other, the UV irradiation efficiency of the photocatalyst functional layer is good. In addition, the photocatalytic functional layer does not become a shadow of equipment and luggage in the room and cannot be irradiated with ultraviolet rays. Further, in the case where the photocatalyst functional layer is provided on a member close to the ultraviolet radiator such as the outer cover, the replacement or cleaning of the member for regenerating the photocatalyst functional layer is limited, so that the maintenance work is easy.

When the photocatalyst functional layer is formed on the louver-shaped outer cover, the ultraviolet rays emitted from the ultraviolet radiator are repeatedly reflected by the photocatalyst functional layer, so that the ultraviolet rays can be effectively utilized, and the inter-blade space is reduced. The circulation of air promotes the contact between the harmful organic compound and the photocatalyst functional layer to enhance the effects of deodorization and pollution control. By using the spontaneous or luminous UV radiator, the activity of the photocatalytic functional layer is maintained even after the lights are turned off at night, and the environment purification of the room equipped with sanitary facilities is continued.

By making the photocatalyst functional layer a porous laminated structure, the photocatalyst semiconductor has a large size; it is possible to bring the photocatalyst semiconductor into contact with the air in the room due to its surface area, and a harmful organic compound that floats in the air causing odors and dirt. Improves the ability to decompose. If you put a black light in the room and turn it on when there are no people in the room and the lighting equipment is not turned on, the strong ultraviolet rays emitted by the black light will maintain the photocatalytic function and decompose the harmful organic compounds. Can be strengthened.
