DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a toilet bowl capable of suppressing odor.

[0002]

2. Description of the Related Art A toilet bowl is provided with a toilet bowl surface for receiving filth, and a discharge port is provided at a lower end of the toilet bowl surface.

For example, in a general Western-style flushing toilet, a toilet bowl surface and a discharge port are connected by a trap, and the toilet bowl surface, the trap, and the discharge port are formed by a ceramic Western-style toilet body. . In such a Western-style flush toilet, a toilet seat and a lid are swingably provided on the Western-style toilet body so as to cover the toilet bowl surface.

[0004] In addition, in a movable Western-style toilet used for the elderly or the sick who have difficulty walking on their own to the toilet room, an Omar is provided below the toilet seat so that it can be taken out. The omaru has a toilet bowl surface and a discharge port, and a storage chamber for storing waste is formed below the discharge port. In such a Western-style toilet, Omar may have a lid covering its outlet.

[0005] Thus, in these conventional toilets, in the Western-style flushing toilet, the lid prevents the smell of filth adhering to the toilet bowl surface from drifting into the atmosphere, and in the movable Western-style toilet, the Omar lid is used. Prevents the body from drifting the smell of dirt in the reservoir into the atmosphere.

[0006]

However, in the above-mentioned conventional toilets, the toilet bowl or the Omar lid merely closes the toilet bowl surface or the discharge port in a sealed state, so that the toilet bowl surface or the toilet bowl is closed. The odor generated from the dirt attached to or stored in the storage chamber is filled with the lid. For this reason, when using such a toilet bowl, if those people open their lids, the odor that was filled would spread at a stretch to the atmosphere, causing discomfort to the user and those around him. Would.

[0007] The present invention has been made in view of the above-mentioned conventional circumstances, and prevents the smell of filth from spreading.
An object of the present invention is to provide a toilet bowl that does not cause discomfort to a user or a surrounding person.

[0008]

The inventor of the present invention has determined that most of the odor generated in the toilet is composed of methane gas and the like, and the specific gravity of the methane gas and the like is lighter than the specific gravity of the atmosphere, and the toilet bowl surface or the discharge port Paying attention to the fact that it is easy to contact with a cover that can be closed, the present invention has been completed.

That is, the toilet of the present invention receives filth,
In a toilet bowl having a toilet bowl surface with a discharge port at the lower end,
The toilet bowl surface or the outlet is provided with a lid that can open the toilet bowl surface or the outlet and that can be closed in a sealed state, and the lid is capable of deodorizing the odor of the filth. It is characterized by having means.

In the toilet of the present invention, the lid closes the toilet bowl surface or the discharge port in a sealed state, thereby preventing the smell of dirt attached to the toilet bowl surface or the like from drifting into the atmosphere. Here, when methane gas or the like, which is a main component of the odor, contacts the lid due to its specific gravity, the methane gas or the like is deodorized by the deodorizing means provided on the lid. Thereby, the filth such as the toilet bowl surface is deprived of the odor, and the inside of the toilet is not filled with the odor.

Therefore, according to the toilet of the present invention, even when the lid is opened, the odor does not diffuse into the atmosphere when the toilet is used, and the user and the surroundings do not feel uncomfortable.

The present invention has a great effect in a toilet constructed so that a storage chamber for storing waste is formed below the discharge port and is configured to be movable. For example, portable toilets with built-in Omar and simple toilets made of Shibin or Omar have been used as movable toilets for the elderly and the sick. In such a portable toilet or a simple toilet, since it is impossible to send waste directly to the sewage from the outlet, a storage chamber for storing waste is formed below the outlet. For this reason, in this type of toilet, particularly, the smell of filth tends to drift into the atmosphere from the storage room, and thus the above effects can be further exerted by providing a deodorizing means on the lid of this type of toilet. .

[0013] In the toilet of the present invention, the lid body has a container-like shape and is capable of sealing the toilet bowl surface or the discharge port, and has a ventilation hole that communicates below the discharge port when the lid body is closed. It is preferable that the lid body includes a deodorant housed in the lid body and a lid that can be opened and closed in a sealed state. When the vent hole provided in the lid body communicates below the outlet, the odor to be filled inside diffuses into the container-like lid through the vent hole. At this time, since the lid body contains a deodorant, the odor is deodorized by the deodorant. For this reason, the above-described effects are obtained. Also, the deodorant,
Because it is housed in the lid body, it can be easily replaced by opening the lid. For this reason, when the deodorizing power of the deodorant decreases, the deodorant can be easily replaced, so that the prevention of odor diffusion can always be exerted.

As the deodorizing means, an ozone generator, an ion-type air cleaner or the like can be employed in addition to the deodorizing agent. Activated carbon is preferably used as the deodorant.
This is because activated carbon is inexpensive and has a high ability to adsorb methane gas and the like. In addition to activated carbon, a porous powder such as sepiolite can be used.
