Abstract

PURPOSE:To suck odors within a toilet by the use of a simple structure even during flushing so as to prevent the odors from diffusing out of the toilet by providing air intakes through the lower or inside surface of a hollow toilet seat, communicating an exhaust pipe with the hollow seat, and providing the exhaust pipe with an exhaust fan. CONSTITUTION:A toilet seat 2 is provided with a passage 5 that extends the overall periphery of the inside of the seat so that the seat 2 is hollowed out. Air intakes 6 are provided through the lower and/or side surface of the seat 2. An exhaust pipe 8 is communicated with the seat 2 and provided with an exhaust fan 9, the extended portion of the exhaust pipe 8 leading to the outside of the toilet room. When the exhaust fan 9 is operated, air in the toilet 1 is sucked through the air intakes 6 via the exhaust pipe 8 and the passage 5, and odors are allowed to pass through the pipe 8 and released outside the room. Since the flow of air is directed into the toilet 1 from outside the toilet 1, the odors are not diffused out of the toilet 1. Therefore, the odors can be sucked even during flushing.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilator for a toilet bowl.

[0002]

2. Description of the Related Art Even with the flush toilets that are currently widespread, the odor immediately after excretion is strong only with an indoor ventilation fan, and it takes a long time to remove the odor.

Therefore, for example, Japanese Patent Publication No. 55-48143 discloses a ventilator which inhales from a rim water passage of a toilet bowl, sucks an odor into the toilet bowl, and releases it to the outside of a toilet by an exhaust pipe.

[0004]

The ventilator described above is designed to prevent odors from rising outside the toilet by sucking the odors into the toilet. However, since the rim water passage is used, it is necessary to inhale while washing. However, there is a problem that the odor leaks out of the toilet bowl.

Further, since the flushing action and the intake action are performed in the same rim passage, there is a problem that a switching means is required, the structure becomes complicated and the cost becomes high.

[0006] Therefore, an object of the present invention is to prevent inhalation of odor to the outside of the toilet by inhaling it in the toilet even when flushing with a simple structure.

[0007]

In order to solve the above-mentioned problems, the present invention provides an intake hole on the lower surface or the inner side surface of a hollow toilet seat, an exhaust pipe communicating with this toilet seat, and an exhaust fan connected to this exhaust pipe. The configuration provided was adopted.

[0008]

When the exhaust fan is operated, the odor is sucked from the intake holes provided on the lower surface or the side surface of the toilet seat, and the odor does not rise outside the toilet bowl.

Further, the intake action can be continued even during washing with water.

[0010]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 and 2, a toilet seat 2 is placed on the upper surface of the toilet 1, and a shaft 3 fixed to the rear end of the toilet seat 2 is rotatably supported by a bearing 4. ing.

As shown in FIGS. 2 and 3, the toilet seat 2 is hollow by being provided with a passage 5 extending all around the inside thereof, and an intake hole 6 is formed on the lower surface and / or side surface of the toilet seat 2.
6a is provided.

As shown in FIG. 4, one of the shafts 3 fixed to the rear end of the toilet seat 2 is hollow, and a passage 5 of the toilet seat 2 is provided.
Is in communication with. A bearing 7 is attached to the outer end of the hollow shaft 3, and an exhaust pipe 8 is connected to the bearing 7.

As shown in FIGS. 1 and 2, the exhaust pipe 8 is
An exhaust fan 9 is provided in the exhaust gas, and an extension of the exhaust pipe 8 is guided to the outside.

As shown by the chain line in FIG. 4, the flexible exhaust pipe 8a may be directly connected to the toilet seat 2 so as to communicate with the passage 5.

Now, when the exhaust fan 9 is operated, the air in the toilet 1 is sucked from the intake hole 6 via the exhaust pipe 8 and the passage 5. At the same time, odor is also released to the outside through the exhaust pipe 8. At this time, the air flow is in the direction from the outside of the toilet bowl 1 to the inside of the toilet bowl 1, so that the odor is not emitted from the toilet bowl 1 to the outside.

1 and 2, reference numeral 10 indicates a tank, but it goes without saying that the tank is not limited to the illustrated low tank.

[0018]

As described above, according to the present invention, since the hollow toilet seat is provided with the intake hole so that the air in the toilet can be sucked in, the odor is not diffused to the outside of the toilet, and even during flushing. Since it can be sucked, it can almost completely deodorize.

Further, since only the exhaust pipe and the exhaust fan are connected to the hollow toilet seat, the structure is extremely simple and cost effective.
