[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toilet bowl which can permanently remove odor from a toilet by adding necessary external factors.

[0002]

2. Description of the Related Art In a conventional deodorizing toilet, an exhaust passage for sucking air from a ball portion and exhausting the outside of the toilet is provided in the toilet, and an adsorbent such as activated carbon is provided in the exhaust passage to convert odor components into the adsorbent. An adsorbent is removed by adsorption, and a fragrance is further provided in an exhaust passage to impart a masking effect by the fragrance.

[0003]

As described above, the conventional deodorizing toilet bowl removes the generated odor by adsorbing it on an adsorbent such as activated carbon, so that when it is exposed to a high concentration of odor components, it is short. Deodorizing performance decreases with time. Also, since there is a limit to the amount of adsorbable components that can be adsorbed by the adsorbent, after use for a certain period of time, remove the adsorbent from the exhaust passage and replace it.
It had to be taken out of the exhaust passage and regenerated. Therefore, a space for detachably storing the adsorbent in the exhaust passage and a special structure for attaching and detaching the adsorbent are required, resulting in a complicated structure and an increase in size. Also,
Not only was the replacement and regeneration of the adsorbent troublesome, but also the running cost for replacing the adsorbent was high.

The present invention has been made in view of the above-mentioned problems of the prior art, and has as its object to provide a space for storing and deploying an adsorbent and a special structure for attaching and detaching the adsorbent. It is an object of the present invention to provide a maintenance-free deodorizing toilet which is not only simple and compact in structure, does not require replacement of an adsorbent and does not require labor for regeneration, and has low running cost.

[0005]

Means for Solving the Problems In order to achieve the above object, in the deodorizing toilet bowl of the present invention, the bowl inner surface of the toilet body is provided with:
A catalyst that adsorbs odor components and promotes the generation of substances that decompose odors due to external factors is attached. Further, the catalyst may be attached to at least one surface of the ball surface of the toilet body, the toilet body, the low tank, and the toilet seat, which are toilet components. As the above-mentioned catalyst, a photoexcited catalyst, an ozone deodorizing catalyst and the like are desirable. In the present invention, the toilet includes not only the toilet body, but also a flush water tank provided integrally or tightly with the toilet seat or the toilet body.

[0006]

In the deodorizing toilet constructed as described above, the catalyst adhering to the pottery surface of the toilet adsorbs not only the odor due to defecation but also various odor components drifting in the toilet room, and furthermore, due to predetermined external factors, The catalyst promotes the generation of a substance that decomposes the odor component, and the generated substance decomposes and removes the odor adsorbed on the catalyst. As a result, the catalyst automatically repeats adsorption and regeneration, and exhibits a permanent deodorizing function. Further, the generated substance decomposes and deodorizes the entire odor in the toilet room, which is floating without being adsorbed by the catalyst.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In the embodiment shown in FIG. 1, a layer 7 ′ of a catalyst 7 that generates a substance that decomposes odor due to an external factor is provided on the inner surface of a ball portion 4 of a toilet body 1 having the same structure as a conventionally well-known general toilet body.
In particular, it is formed in a layer on the surface 4 'above the water retaining surface.

[0008] The catalyst 7 is photoexcitation catalyst, for example SnO ₂ for wavelength tuning in TiO ₂ or Ti0 _2,
It is composed of a material to which additives such as WO ₃ and Y ₂ O ₃ are added, and is activated by absorbing light energy by light irradiation and being excited to drive an oxidation and reduction reaction. The catalyst is applied to the toilet body 1 after firing by spraying or the like to form a layer, or the catalyst 7 is applied to the toilet body 1 before firing and fired together with the catalyst 7 during firing to form a layer. Form. Further, the layer 7 'of the photoexcited catalyst 7 has a large specific surface area for temporarily adsorbing and holding malodorous substances. The catalyst 7 is layered and integrally formed on the ball portion surface 4 ′ above the water retaining surface of the ball portion 4 of the toilet body 1, preferably on the inner peripheral surface of the upper edge rim portion 5.

On the other hand, a photocatalyst excitation light source 9 for irradiating the photoexcitation catalyst 7 with light has a wavelength of 4, which is light having energy equal to or more than the band gap of the photoexcitation catalyst.
It consists of a short-wavelength light lamp that irradiates a light beam containing ultraviolet rays of 10 nm or less, and it can be installed in various places such as on the toilet room ceiling or on the toilet seat 11 as illumination of the toilet room. It is preferable to install on the toilet seat 11 so as to face.

According to the deodorizing toilet of this embodiment, the odor generated in the ball portion 4 due to defecation or the like is adsorbed by the photoexcited catalyst layer 7 'on the ball surface 4'. As a result, the photoexcited catalyst layer 7 'has 410n
Since the light containing ultraviolet rays of m or less is irradiated, the photoexcited catalyst has an odor component decomposing action, and the odor component adsorbed on the photoexcited catalyst layer 7 'is decomposed and deodorized. Then, the adsorption power of the photoexcited catalyst layer 7 'is restored by the decomposition of the odor component.

In such a catalyst in which a catalyst that generates a component that decomposes an odor component due to an external factor is adhered and formed on the inner surface of the ball portion 4 in a layered manner, instead of the photoexcited catalyst 7, the odor component is adsorbed. In addition, a catalyst that generates a substance that decomposes odor components by reacting with a specific chemical is formed in a layer on the inner surface of the ball portion above the water retaining surface, and the above chemical is added to the cleaning water in the low tank for cleaning. If the chemical is supplied to the bowl together with the water, the toilet bowl can capture not only the dirt but also the odor, and the dirt and the odor can be washed away with the washing water.

Next, in the embodiment shown in FIG. 2, the layer 7 'of the catalyst 7, which generates a substance that decomposes odor due to an external factor, is formed over a large area of the toilet, so that only the odor during defecation is reduced. Instead, it is intended to deodorize and remove various odors in the entire toilet room. A photo-excited catalyst 7 is used as a catalyst for generating a substance that decomposes odors due to external factors, and the photo-excited catalyst 7 is tightly connected to the toilet body 1 and this. The raw tank 12 is integrally attached to the entire outer surface of the raw tank 12. In the case of this embodiment, the photocatalyst excitation light source 9 is installed on the toilet wall or floor as shown.

According to this embodiment, the photoexcited catalyst layer 7 'adsorbs odor components in the toilet room, and when the photocatalyst excitation light source 9 is turned on, the photoexcited catalyst layer 7' is irradiated with light rays containing ultraviolet rays of 410 nm or less. Therefore, the odor component is decomposed in the photoexcited catalyst 7, and the odor component adsorbed on the photoexcited catalyst layer 7 'is decomposed and deodorized. Therefore, the entire toilet room can be deodorized.

In each of the two embodiments described above, an exhaust passage for sucking air from the ball portion and discharging the air out of the toilet is provided in the toilet body, and an odor component is adsorbed on the inner surface of the exhaust passage. Compared to a structure that attaches a catalyst that promotes the generation of substances that decompose odors due to external factors, no space is required for deodorization and no exhaust passage is required. There is an advantage that it is not necessary to use a special structure having a passage, and a conventional general toilet can be used. Further, there is an advantage that a power source such as a fan is not required, and noise from the fan and noise from the inlet of the exhaust passage due to intake of air are not generated.

[0015]

[Effect] Since the present invention is configured as described above, the following effects can be obtained. (1) Since a space for storing and deploying the adsorbent and a special structure for attaching and detaching the adsorbent are not required, the structure is simple and compact. (2) Since there is no need to replace or regenerate the adsorbent, it is maintenance-free and running costs are low. (3) A catalyst that promotes the generation of a substance that decomposes odor components due to external factors is formed on the inner surface of the ball portion or the outer surface of the toilet bowl, so there is no need to send the odor with a fan. There is no noise such as fan noise and air intake noise into the exhaust passage.
