Description of the Related Art Conventionally, a deodorizing duct having a suction port facing a ball portion of a toilet body is provided inside a casing installed in the toilet body as a means for exhausting a bad smell generated at the time of stool and an odor staying in a toilet. An exhaust fan that sucks air from the suction port provided in communication with the deodorizing duct and exhausts the air to the outside of the casing, and further provides an ozone generator upstream of the exhaust fan to generate air during use. There is an example provided with a deodorizing mechanism for deodorizing an unpleasant odor or odor staying in the toilet. (See Japanese Patent Application Laid-Open No. 4-176925) This deodorizing mechanism sucks, into the deodorizing duct, air containing an unpleasant odor accumulated in the bowl portion of the toilet body by operating an exhaust fan, and at this time, an ozone generating device is used. The ozone generated by the air is discharged into the exhaust passage from the deodorizing duct to the exhaust fan, mixed with the suctioned air containing the unpleasant odor and sent to the deodorizing duct, and the air sent to the deodorizing duct is used for ozone reduction. In addition to the manganate oxide, volatile glyoxal, methacrylic acid ester, and fragrance, etc., are deodorized and aroma imparted by a catalyst enclosing a deodorant liquid and an aromatic liquid, and the odor is completely removed. It is designed to be exhausted.

It is not intended until sterilization, and it is said that it is very difficult to regenerate deodorizing agents and fragrances after reacting with malodorous substances.

が一般的に知られている。On the other hand, malodorous components such as toilet odor include a wide variety of components from low boiling components to high boiling components such as nitrogen compounds such as ammonia, hydrogen sulfide, sulfur compounds such as methyl mercaptan, and acetaldehydes. (JP-A-1-
As a method for deodorizing such malodors, a method of filtering malodorous substances with a deodorizing agent disclosed in JP-A-2-224628 and a method of masking malodorous substances with a fragrance disclosed in JP-A-1-27736 have been used. Method, JP-A-63
A method of adsorbing malodorous substances with activated carbon or zeolite according to JP-63466-A, and a method of concentrating and reacting a malodor with an adsorbent to which a drug is attached as disclosed in JP-A-63-63466 are generally known. I have.

表的な例として図３に示すようなものがある。FIG. 3 shows a typical example of a deodorizing apparatus to which the latter two methods are applied.

る。In this apparatus, reference numeral 21 denotes a casing, in which a pre-filter 23 for collecting dust, an activated carbon layer 24, and a blower 27 are arranged sequentially from the windward side. The casing 21 is provided with a suction grill 22 on the windward side of the pre-filter 23,
A blow grill 20 is provided on the lee side of 27.High boiling compounds can be physically absorbed because activated carbon is used as a deodorant in this device, but low boiling nitrogen compounds such as ammonia and methylamine and formalin and acetaldehyde are used. It is said that low-boiling compounds such as these have poor deodorizing performance.
【０００８】かかる問題を解決するために薬品を活性炭

ものと交換しなければならないという問題がある。However, in the activated carbon to which chemicals are impregnated, the high-boiling compounds are physically adsorbed by the activated carbon itself.
It is possible to regenerate activated carbon by heating, but it is difficult to regenerate chemicals as adsorbents because low-boiling nitrogen compounds and low-boiling aldehydes are adsorbed by reaction with the attached chemicals. In addition, when the physical adsorption capacity of activated carbon is saturated, the odor is exhausted when clean air enters, so the life of activated carbon impregnated with this chemical is shortened from several months to half a year, and it is periodically replaced with a new one. There is a problem that must be done.

There is a problem that must be replaced.

Since the electric lamp 17 that emits ultraviolet light is positioned orthogonal to the surface of the fin 15a, the air containing the malodorous component sucked into the case 11 is not irradiated with sufficient ultraviolet light and the surface of the fin 15a Irradiation of ultraviolet rays to the photocatalyst layer 14 becomes insufficient, and the deodorizing effect of the malodorous component must be insufficient.

る。[Function] Odor absorbing member A that adsorbs different kinds of odor components
By providing B on the intake port side and the exhaust port side of the case, mixing of the product due to the adsorbed odor component is avoided, and the gas permeability is reduced by making the odor absorbing member B smaller in permeability than the odor absorbing member A. The adsorption load is not applied only to the odor absorbing member A on the side of the intake port having a high concentration, and a photocatalytic layer is formed on the odor absorbing members A and B.
Since the ultraviolet light source is interposed between B and B, the photocatalyst layer is effectively irradiated with ultraviolet light to excite it, and the air passing between the odor absorbing members A and B is also effectively irradiated with ultraviolet light. By absorbing the specific single gas by the absorbing member A and the general gas by the odor absorbing member B, the odor absorbing member A can collectively absorb a specific single gas having a characteristic depending on the place of use, for example. The post-odor absorbing member B absorbs all the gases other than the above-mentioned gases.
