められている。2. Description of the Related Art In recent years, with the increase in awareness of environmental hygiene, air conditioners having deodorizing and sterilizing functions for deodorizing and sterilizing indoor odors and odors generated from office equipment such as copiers. Devices, air conditioners, air purifiers and the like have been widely used. In particular, in the case of aged reinforced concrete buildings and buildings with problems in the design of health and hygiene, the problem of air pollution in the buildings has become apparent, and air conditioners such as air conditioners, air conditioners, humidifiers, etc., which have a deodorizing function and a sterilizing function. Equipment is needed.

防護手段の設置や使用上の制約があった。Conventionally, deodorization is generally performed by an odor-adsorbing substance such as activated carbon, and sterilization is performed by irradiation of ultraviolet rays or ozone. Since odor-adsorbing substances such as activated carbon become saturated in a relatively short period of time, they need to be replaced, and irradiation of ultraviolet rays and use of ozone may be harmful to the human body.
There were restrictions on the installation and use of protective measures.

菌に好適である。Recently, a deodorant in which a photoreactive semiconductor such as titanium oxide is combined with an adsorbent such as activated carbon has been developed and put into practical use. This deodorant is active oxygen generated by decomposing water vapor and oxygen in the atmosphere when ultraviolet light is irradiated on the photoreactive semiconductor, and has a function to decompose and sterilize odor substances and bacteria adsorbed by adsorbed substances. Since it is possible to regenerate a saturated adsorbed substance and exhibit a bactericidal effect, it is suitable for deodorization and sterilization having the above-mentioned deodorizing function and sterilizing function.

For this reason, it is not suitable for use in an environment where the deodorization load is continuous under a high load state higher than the photolysis rate, but the load pattern is composed of a combination of a short high deodorization load and a long low deodorization load. It is a suitable deodorant and suitable for use in deodorizing / sterilizing equipment used in places such as homes and offices that have a temporary high deodorizing load during the day and a low deodorizing load during the night. It is a deodorant.

しい。In the present invention, the ultraviolet light source is a columnar straight tube type ultraviolet light source on which the cylindrical titanium oxide supporting sheet honeycomb structure is easily mounted. Further, as described above, the light receiving efficiency is highest when the honeycomb structures are mounted in direct contact with each other so as to surround the cylindrical straight tube type ultraviolet light source. However, when the contaminated air passes through the honeycomb space, the contaminated air comes into contact with the honeycomb structure more efficiently. Therefore, if the ultraviolet light receiving intensity of the honeycomb structure is in a range that does not decrease so much, do not directly contact,
The honeycomb structure may be mounted so as to surround the cylindrical inner peripheral surface of the honeycomb structure and the outer peripheral surface of the ultraviolet light source while maintaining a predetermined interval. However, in this case, the distance between the inner peripheral surface of the honeycomb structure and the outer peripheral surface of the ultraviolet light source is desirably 1 cm or less.

所に適宜間隔で挿入すればよい。In order to maintain the above distance, at least one ring-shaped spacer corresponding to the distance between the inner peripheral surface of the honeycomb structure and the outer peripheral surface of the ultraviolet light source must be inserted at a key point. There is. The shape of the spacer differs depending on the direction in which the contaminated air flows and the installation direction of the honeycomb structure. For example, as shown in FIG. 1, when the honeycomb structure is installed so as to be orthogonal to the flow of the contaminated air,
The shape of the spacer may be a circular ring shape, and may be inserted at appropriate intervals at a key point of the ultraviolet light source.

流れる。When the contaminated air flows along the outer peripheral surface of the honeycomb structure in the longitudinal direction or both the outer peripheral surface of the honeycomb structure and the inner peripheral surface of the cylindrical structure, the shape of the spacer is set along the outer peripheral surface of the ultraviolet light source. A spiral shape may be inserted at a key point along the outer peripheral surface of the ultraviolet light source such that one or more of the spiral shapes are parallel to each other. The spiral spacer serves as a guide for the contaminated air to flow along the outer peripheral surface of the columnar ultraviolet light source, and does not block the flow of the contaminated air along the cylindrical inner peripheral surface of the honeycomb structure. It flows while drawing a spiral trajectory in the longitudinal direction of the light source.

い。The apparent thickness of the honeycomb structure, that is, the difference between the outer radius and the inner radius, is 0.5 in consideration of the efficiency of receiving ultraviolet light emitted from the ultraviolet light source and the efficiency of contact with odorous substances and bacteria. 3 cm is desirable. In the case of the present invention, since the shape of the ultraviolet light source is a cylindrical straight tube type, the direction in which the strongest ultraviolet light is emitted is the radial direction of the cylindrical ultraviolet light source. Therefore, it is desirable that the sheets constituting the walls of the honeycomb space face each other so that the incident angle with respect to ultraviolet rays emitted from this direction is within a certain range.

受光効率がよくない。The most frequently used honeycomb is a core material for reducing the weight of interior walls such as doors and floors. Honeycomes used in such applications are in a flat plate shape and constitute the walls of each honeycomb space. The sheet is orthogonal to the surface of the flat plate.
When the cylindrical honeycomb structure of the present invention is made from the honeycomb having such a structure, the cross-sectional shape becomes as shown in the lower diagram of FIG. 6, and the sheets constituting the walls of each honeycomb space are parallel to the radial direction of the ultraviolet light source. Because many parts of the ultraviolet light pass through the honeycomb space and leak to the outside,
Light receiving efficiency is not good.

接触効率を高める効果もある。Therefore, in order to minimize the amount of ultraviolet rays radiated from the ultraviolet light source leaking out of the honeycomb structure, most of the sheets of the six walls surrounding the hexagonal honeycomb space are shown in FIG. As in the honeycomb structure shown in FIG. 5, it is desirable to have a structure that faces the ultraviolet light source at a certain angle or more with respect to the radial direction of the ultraviolet light source. As described above, inclining the sheet of the wall constituting the wall surrounding the honeycomb space also has the effect of increasing the contact efficiency with the contaminated air.

It is also possible to greatly enhance the function. Particularly, it is best to use a double or triple mounting.

きる。In order to efficiently contact the contaminated air with the titanium oxide supporting sheet, as shown in the upper part of FIG. 6, most of the sheets surrounding the walls of the honeycomb space are opposite to the flow direction of the contaminated air. It is desirable to dispose the honeycomb structure in the direction of the eye gradient. By doing so, more contaminated air that has collided with the honeycomb structure can be guided into the inside of the honeycomb space, and ultraviolet rays emitted from the ultraviolet light source can be prevented from leaking out of the honeycomb structure.

のである。When the contaminated air is guided into the inside of the honeycomb space, when the contaminated air comes into contact with the walls of the honeycomb space, a turbulent flow composed of countless vortices is generated, and the contaminated air is efficiently dissipated to the inside of the titanium oxide supporting layer of the sheet. Penetrates deeply into odorants,
The most efficient photolysis and removal of contaminated air containing bacteria and the like. In this way, the contaminated air flows while efficiently contacting the cylindrical titanium oxide supporting sheet honeycomb structure, so that odorous substances and bacteria contained in the contaminated air are decomposed or sterilized, and purified air is discharged from the outlet.

Therefore, it is convenient to form a unit in which a cylindrical straight tube type ultraviolet light source is stored in a cylinder of a cylindrical titanium oxide supporting sheet honeycomb structure as a deodorizing antibacterial unit. By unitizing, an appropriate number of units can be arranged as needed inside the air conditioner, and an appropriate number of the deodorizing antibacterial units arranged can be energized and operated as necessary, as needed.

こると考えられる。The sheet in which the photoreactive semiconductor constituting the honeycomb structure is supported on the sheet surface can be manufactured, for example, by the following method. First, a fine powder of titanium oxide, which is a photoreactive semiconductor, is dispersed in water together with a dispersant, and then a colloidal solution of silica or alumina is added at a fixed ratio and stirred for several hours. Thereafter, an organic polymer binder is added and stirred to prepare a titanium oxide paint dispersion, which is applied to both sides of the above-mentioned sheet and dried to obtain a target titanium oxide coat sheet. During the drying step after the coating, first, the composite of titanium oxide fine particles and silica or alumina composed of ultrafine particles having a particle diameter of millimicron order occurs preferentially to form titanium oxide composite particles. Subsequently, it is considered that the binding between the titanium oxide composite particles by the organic polymer binder and the fixation to the sheet occur.

カム構造体が得られる。Thus, the titanium oxide fine particles form titanium oxide composite particles with the silica or alumina fine particles, and the titanium oxide composite particles have an infinite number of pores through which gas molecules can pass. The molecules can easily reach the surface of the titanium oxide fine particles. For this reason, it is considered that the titanium oxide fine particles do not directly contact the binder and the sheet, maintain high photocatalytic activity, and do not decompose the binder and the sheet. The thus obtained titanium oxide coated sheet is processed into a honeycomb shape, and further formed into a cylindrical shape, thereby obtaining a cylindrical titanium oxide coated sheet honeycomb structure.
