DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for removing odors generated in a toilet to the outside and a flush toilet for removing odors.

[0002]

2. Description of the Related Art Toilets are small and confined spaces.
The unpleasant smell of urine generated in the space tends to be muffled inside. I don't care much about my own odor,
Other people's excrement smell is very unpleasant. In recent years, single-family houses, apartment houses, and the like have good airtightness throughout the building, and therefore, ventilation is performed so that manure generated in the toilet does not leak into other rooms. In general, for ventilation, a duct is passed between a wall or a ceiling of a toilet and an outer wall, a ventilation fan is provided in the duct, and ventilation and deodorization in the toilet are performed by turning the ventilation fan. In addition, a fragrance is installed in the toilet, and the odor of the fragrance is used to eliminate the odor. Further, there is provided a device in which a deodorizing device is attached to a side surface of a toilet and the odor is discharged during use.

[0003]

SUMMARY OF THE INVENTION The exhaust odor caused by the ventilation fan is
It was impossible to suck and exhaust the odorous main component having a specific gravity several times that of air at a high position away from the toilet, and the toilet had a bad smell and could not be discharged in a short time. Therefore, it is not enough to eliminate the discomfort of the user who enters later.

[0004] When a fragrance is installed in a toilet, a good fragrance peculiar to the fragrance is smelled when entering the lavatory, but after the stool, the fragrance and manure smell are mixed in the lavatory. It smelled, and again gave discomfort to the next user. In particular, since the fragrance does not have a deodorizing function, it has no effect on deodorization. Further, in the case of a deodorizing device installed in a toilet, there is an advantage that it can be easily attached to an existing toilet, but there is a problem that it is expensive and it is dirty due to male urination.

The present invention has been made in view of the above-mentioned various problems, such as the conventional ventilation in the toilet and deodorizing means, to provide a discharge pipe for discharging flush water from a low tank to a toilet in order to wash the interior of the toilet after stool. It is an object of the present invention to provide a method of deodorizing in a toilet which can be used to efficiently excrete feces and urine in a toilet and enable ventilation in the toilet. Another object of the present invention is to provide a flush toilet for exhausting odor.

[0006]

In order to achieve the above object, the present invention relates to a method of connecting a toilet bowl 1 and a low tank 2 by a discharge pipe 3 to discharge and clean manure in the toilet bowl 1 through the discharge pipe 3. In the flush toilet, the tip of the exhaust pipe 5 connected to the discharge pipe 3 is connected to the outside and the exhaust pipe 5 is connected.
The exhaust fan 6 is installed in the middle of the process.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows an embodiment of a flush toilet used in the method of the present invention. In the figure, reference numeral 1 denotes a toilet bowl, 2 denotes a low tank for storing flush water, and the toilet 1 and the low tank 2 are discharged. They are connected by a pipe 3.

When the handle 4 provided on the side surface of the low tank 2 is rotated after urination of urine or urine, a chain (not shown) connected to the handle 4 in the low tank 2.
Is lifted up, and the spherical valve element connected to the lower end of the chain opens the discharge port installed in the lower part of the low tank 2, and the washing water stored in the low tank 2 passes through the discharge pipe 3 and flows into the toilet 1. And excreted manure through the drain.

A plurality of holes (not shown) for discharging flush water into the toilet 1 in a flush state are formed in the upper edge portion of the toilet 1, so that the flush water is supplied from the entire peripheral edge of the toilet 1. It will be ejected. These structures and cleaning operations are the same as those of a conventional flush toilet.

In the present invention, the toilet 1 and the low tank 2
The exhaust pipe 5 is connected in the middle of the discharge pipe 3, which is preferably connected to the upper part of the discharge pipe 3, and the tip of the exhaust pipe 5 is directed to the outdoors. An exhaust fan 6 is provided, and the odor generated in the toilet 1 is discharged to the outside through a discharge hole → a discharge pipe 3 → an exhaust pipe 5 formed in the toilet 1.

The discharge pipe 3 between the toilet 1 and the low tank 2 is normally in a hollow state without washing water, and the discharge hole formed in the toilet 1 and the discharge pipe 3 can be ventilated. Therefore, if the exhaust fan 6 is rotated during the toilet, the exhaust in the toilet 1 is performed through the discharge hole of the washing water formed in the toilet 1, and the feces and odor generated in the toilet from the toilet 1 is reduced. All of them are discharged outside through the exhaust pipe 5 during use. After use, the exhaust fan 6 is stopped, the cleaning water is discharged by operating the handle 4, and the excrement in the toilet 1 may be discharged for cleaning. The rotation and stop of the exhaust fan 6 can use the conventional electric drive mechanism of the ventilation fan as it is.

In the above description, the exhaust fan 6 is manually operated.
However, the present invention is not limited to this. For example, when the toilet door is opened, the exhaust fan 6 is rotationally driven by a switch input by the switch, and electrically operated so that the exhaust fan 6 stops when the handle 4 is rotated to discharge the washing water after the stool. If connected, deodorization work can be performed automatically. Such an automatic mechanism is merely an example, and any other operating mechanism can be used as long as the inside of the toilet 1 can be evacuated using the discharge pipe 3. FIG. 1 shows the case of a Western style toilet, but the present invention is not limited to this, and can be used for a Japanese style toilet.

[0013]

According to the present invention described above, the toilet 1
The exhaust pipe 5 is connected to the discharge pipe 3 connecting the exhaust pipe 5 and the low tank 2. The exhaust fan 6 is installed in the middle of the exhaust pipe 5, and the tip of the exhaust pipe 5 is guided outside, so that the exhaust fan 6 is rotated. By operating, air in the toilet 1 and in the toilet can be sucked using the discharge hole of the toilet 1.

Therefore, if the exhaust fan 6 is rotated during the stool, the urine odor can be directly discharged from the toilet 1 to the outside, and the urine odor does not stay in the toilet, and the next user can use it. No discomfort. In addition, ventilation in the toilet can be performed simultaneously with deodorization.

Since the exhaust pipe 5 is connected to the discharge pipe 3 and the exhaust pipe 5 is provided with the exhaust fan 6 and the tip of the exhaust pipe 5 need only be guided to the outside, it can be easily installed in an existing toilet. With a simple structure, a sufficient deodorizing effect can be obtained.
