[Prior Art]

 With the thorough maintenance of sewerage systems in recent years, the use of septic tanks is obligatory in each house, and the spread of flush toilets that purify toilet excreta in septic tanks and then discharge the sewerage is promoted. In this way, manure from the toilet cannot be flushed into the sewer until it has been purified in the septic tank. As for these flush toilets, overwhelmingly many Western-style toilets are used to sit down on the toilet seat and excrete excrement so that they can be used continuously for a long time. The western-style toilet has a box-shaped toilet body, a toilet seat that can be freely opened and closed on the toilet body, and a lid that covers the toilet seat and covers the toilet body. A tank that supplies a fixed amount of water that discharges excrement excreted into the body of the toilet is connected to this toilet body by a pipe. Since this Western-style toilet with a Western-style toilet grounded is a narrow space, a ventilation fan is installed to prevent the odor from excrement from filling the toilet. This toilet ventilation fan is usually mounted on a high window or on the ceiling.

[Problems to be solved by the device]

 However, if you want to excrete excrement by sitting on a Western-style toilet in a Western-style toilet, lower your underwear, open the lid (not shown in Figure 3) as shown in Figure 3, and place your waist on the toilet seat 3. Lower it. When the person sits down on the toilet seat 3, the person sits with a slight gap between the person's crotch and the front end of the toilet body 2 so that the person's crotch does not hit the toilet body 2. Then, the person's buttocks 4 are placed on the rear end of the toilet seat 3 as shown in FIG. When excreting the excrement while sitting on the toilet 1 in this manner, the excreted excrement falls into the toilet body 2. The manure that has fallen into the toilet body 2 is accumulated in the toilet body 2, and the odor emitted from the accumulated manure is between the crotch of the person, which is the only opening above the toilet seat 3, and the front end of the toilet body 2. Stand up from and hit a person's nose directly. In this case, even if the toilet ventilation fan is operated, the toilet ventilation fan is installed on the high window or on the ceiling, so the odor rising from inside the toilet body 2 passes through the front of the person's face. It is then exhausted to the outside through the fan of the ventilation fan. For this reason, people who excrete excrement seriously inhale the odor emitted from their excrement, and even if they have a toilet ventilation fan, if they excrete excrement, the deodorizing effect cannot be expected. have.

The present invention has been made in view of the above problems of the prior art. The purpose of the present invention is to provide a person who excretes feces and urine to seriously detect the odor emitted from excrement excreted by himself. It is intended to provide a toilet ventilation fan that can efficiently exhaust the odor in the toilet bowl so that it is not sucked into the toilet.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the toilet ventilation fan according to the present invention is provided with a ventilation duct opening in the toilet body, and a fan is attached to the ventilation duct midway or at the tip of the ventilation duct tip.

[Action]

 When you sit down on a Western style toilet and excrete excrement, operate the toilet ventilation fan. Then, open the lid, put down the underwear, and sit down with a slight gap between the person's crotch and the front end of the toilet bowl so that the person's crotch does not hit the toilet bowl on the toilet seat. Then, the gap between the person's crotch and the front end of the toilet body is the only opening above the toilet seat. At this time, since the toilet ventilation fan operates to discharge the air inside the toilet body to the outside of the room, the inside of the toilet body becomes a negative pressure than the inside of the toilet room, and the gap between the crotch of the person and the front end of the toilet body is reached. The air in the toilet room is sucked in, and the air in the toilet body is continuously exhausted to the outside of the toilet room. Therefore, when a person excretes manure, the excreted manure falls and accumulates in the body of the toilet bowl. The odor emitted from this excreted manure is pulled by the fan together with the air in the toilet room that is drawn into the toilet body through the gap between the crotch of the person and the front end of the toilet body, and passes through the ventilation duct of the toilet ventilation fan. Exhausted outside the toilet room.

The washing water tank 7 is adapted to be supplied with water from a predetermined water supply passage (not shown) as needed. The washing water tank 7 is fixed to a wall or the like by a fixing tool. The valve 8 is an item that is opened when a certain amount of water contained in the flush water tank 7 is supplied into the toilet body 2 to flush out excrement, and is normally closed.

A toilet ventilation fan 10 is composed of a ventilation pipe 11 and a fan 12. One end of the ventilation pipe 11 is opened inside the toilet body 2, and the other end is exposed outside the toilet room. The fan 12 is provided at the tip of the ventilation conduit 11. Although the fan 12 is provided at the tip of the ventilation conduit 11 in this embodiment, it may be provided in the middle of the ventilation conduit 11 by using a sirocco fan.

Next, the operation of this embodiment will be described.

First, when the user sits down on the Western-style toilet 1 and excretes manure, the toilet ventilation fan 10 is operated. Then, open the lid 5, lower the underwear, and sit down on the toilet seat 3 with a slight gap between the person's crotch and the front end of the toilet body 2 so that the person's crotch does not hit the toilet body 2. .. Then, the gap between the person's crotch and the front end of the toilet body 2 becomes the only opening above the toilet seat 3. At this time, since the toilet ventilation fan 10 is operated to discharge the air in the toilet body 2 to the outside of the room, the inside of the toilet body 2 has a negative pressure than that in the toilet room. The air in the toilet room is sucked in through the gap, and the air in the toilet body 2 is continuously exhausted to the outside of the toilet room. Therefore, when a person excretes the excrement, the excreted excrement falls into the toilet body 2 and accumulates. The odor emitted from the excreted excrement is pulled by the fan 12 together with the air in the toilet room sucked into the toilet body 2 through the gap between the crotch of the person and the front end of the toilet body 2, and the ventilation pipe of the toilet ventilation fan 10 is pulled. The air is exhausted to the outside of the toilet room through the passage 11.

Therefore, according to the present embodiment, the odor emitted from the excrement excreted by oneself does not rise from between the crotch of the person and the front end of the toilet body 2 and directly hits the nose of the person, It is possible to prevent the odor rising from the manure from being seriously inhaled.

FIG. 2 shows another embodiment of the toilet ventilation fan according to the present invention. In the figure, 1 is a Western-style toilet bowl, 2 is a toilet bowl body, 3 is a toilet seat, and 5 is a lid portion, which are the same as in the embodiment shown in FIG.

Reference numeral 6 denotes a flush pipe, one end of which opens into the main body 2 of the toilet, and the other end of which is opened through a valve 8 to a flush water tank 7 in which a fixed amount of water is always stored. The washing water tank 7 is adapted to be supplied with water from a predetermined water supply passage (not shown) as needed. The washing water tank 7 is fixed to a wall or the like by a fixing tool. The valve 8 is an item that is opened when a certain amount of water contained in the flush water tank 7 is supplied into the toilet body 2 to flush out excrement, and is normally closed.

A toilet ventilation fan 20 is composed of a ventilation pipe 21 and a fan 22. One end of the ventilation pipe 21 is opened inside the flush pipe 6, and the other end is exposed outside the toilet room. The joint of the ventilation conduit 21 with the washing water conduit 6 may be performed by direct welding or the like, or by using a pipe joint. The fan 22 is provided at the tip of the ventilation pipe 21. Although the fan 22 is provided at the tip of the ventilation conduit 21 in this embodiment, it may be provided in the middle of the ventilation conduit 21 by using a sirocco fan. When the fan 22 is operated, the air in the toilet body 2 passes through the flush conduit toilet 6 and enters the ventilation conduit 21 from the origin of the ventilation conduit 21 and is exhausted outside the toilet room. Even if the ventilation pipe 21 is connected to the washing pipe 6 in this manner, there is no particular problem because the washing pipe 6 is not used except during washing. In addition, even if the toilet ventilation fan 20 is used to flush water while using it, the fan 22 does not have the power to suck up the water flowing through the flush pipe 6 into the ventilation pipe 21. Crawl up to reach fan 22. Connecting the ventilation conduit 21 to the flush conduit 6 is easier than constructing a hole in the toilet body 2 and connecting the ventilation conduit 21.
