Abstract

PROBLEM TO BE SOLVED: To improve exhaust of odor from excretions by taking air in a toilet from an inlet port positioned above a man's organ of smell and exhausting odor of excretions from an exhaust port positioned below the man's organ of smell. SOLUTION: First, odor in a toilet stool 4 is guided downward not to reach the position A of a man's organ of smell. That is, the air in a toilet is taken from an inlet port 3 positioned above the level of a man's organ of smell, and the odor of excretion is exhausted to the outside from an exhaust port 1 positioned below the position A of the man's organ of smell. Further to keep the odor in a toilet stool 4 being discharged to the outside of the toilet stool 4, a toilet stool seat provided with inlet holes in the periphery of the toilet stool is arranged to collect odor to be guided to an exhaust pipe connected to the outside. Accordingly, the inlet port and the exhaust port are disposed on the upper and lower sides, so that the human body is covered with fresh air and the odor can be discharged without reaching the man's organ of smell.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to the deodorization of toilets for large and small urines.

[0002]

2. Description of the Related Art In order to make a toilet odorless, a plurality of devices for providing an air intake hole in a toilet and discharging odor have already been made (Japanese Patent Application Laid-Open Nos. 62-172926 and 02-28253).
0, JP-A-04-202925).

[0003] However, these are improvements related to the toilet, and the toilet has not been solved as a system including a toilet, a room, a person, and a suction / exhaust port as a whole to solve the problem of odor.

[0004]

In the conventional toilet, the odor of the excrement in the toilet fills the entire toilet room in spite of the presence of the ventilation fan, and gives an odor not only to the excretor but also to the following excretor. . In addition, it is extremely unpleasant to drift around the outside of the toilet with the opening and closing of the toilet door. An object of the present invention is to solve the problem of the unpleasant odor of excrement as described above.

[0005]

[Means for Solving the Problems] Although the toilet is a part of the building, as described above, the toilet itself forms a single system with the toilet, the room, the person, and the air intake / exhaust port. In order to solve the problem, the system is basically solved at two points as follows. 1. In order for excretors not to perceive the odor of excrement,
Consider the mutual location of the odorous toilet bowl, the odor organs of the person who perceives the odor, and the air intake / exhaust port that controls the convection of the toilet room. In other words, in order to prevent the odor emitted from the toilet during urination and urination from reaching the position of the human olfactory organ, the intake and exhaust ports of the room are arranged, the intake and exhaust volume is optimized, and the convection in the toilet is optimally designed. To 2. The odor of excrement is collected in the toilet and discharged to the outside so that it does not spread throughout the toilet room. Once the odor has diffused into the room, it takes time to discharge, which causes discomfort to subsequent excretors. Also, when the door of the toilet is opened, odor leaks out of the toilet. First, in the structure of the conventional toilet, as shown in FIG. 10, an intake port 3, a toilet 4, a position A of a human olfactory organ, an exhaust port 1 and an exhaust fan 2 are arranged upward from the floor. Therefore, the odor in the toilet bowl is guided upward together with the clean external air coming from the intake port 3 and is discharged from the upper exhaust port 1 through the position A of the human olfactory organ. Therefore, ironically,
The conventional design structure has an appropriate convection design to feel the odor. Further, the odor emitted from the toilet 4 is exhausted from the exhaust port 1 while diffusing upward in the entire room, instead of stopping in the toilet. Therefore, the odor spreads throughout the room.
To charge. The present invention has been made in view of the above-described conventional drawbacks, and has as its object to provide an odorless toilet that solves the problem of odor from excrement.

To achieve the above object, the present invention provides:
First, the odor in the toilet 4 is guided downward so that it does not reach the position A of the human olfactory organ. That is, the air in the toilet is taken in from the intake port 3 located above the level of A, and the odor of the excrement is discharged outside through the exhaust port 1 located below A.

Further, in order to prevent the odor in the toilet 4 from going out of the toilet 4, a toilet seat provided with an intake hole is arranged around the toilet to collect the odor and guide the odor to an exhaust pipe connected to the outside. It is useful to provide an air intake hole in the toilet itself, but remodeling a large casting mold such as a toilet is expensive and cannot be applied to an existing toilet.

When an existing toilet is used as well as a toilet, an odor collector having an intake hole that can be inserted into a gap between the toilet and the toilet seat is provided to collect odor and guide the odor to an exhaust pipe connected to the outside.

When the conventional toilet structure shown in FIG. 10 is to be used as it is, an exhaust pipe is connected to the exhaust port 1, and
The other end of the exhaust pipe is arranged around the toilet 4 to collect the odor of the excrement at a level lower than the position A of the human olfactory organ.

Incidentally, when the structure of the simple flush toilet as shown in FIG. 6, that is, when the evacuation outlet and the exhaust port at the lower part of the toilet are the same, the conventional toilet has a function as shown in FIG. Since the intake port is sealed by the exhaust port lid, the odor fills the toilet. Therefore, in the present invention, as shown in FIG. 2 (b), an intake hole is provided in the discharge lid, and odor is always collected from the intake hole, and is discharged outside the building by the exhaust fan through the toilet tank. An air inlet may be provided in the toilet in contact with the outlet lid, but the cost of changing the type of toilet is high.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the embodiments shown in the drawings. FIG. 1 shows a first embodiment.
By arranging the air inlet 3 above the position A of the human olfactory organ, the human body including the human olfactory organ is covered with clean air. Thereafter, the clean air mixes with the odor in the toilet at the position of the toilet and is discharged from the exhaust port 1 located below. With this structure, the odor does not reach the human olfactory organ.

FIG. 2 shows a toilet seat 5 that can easily collect the odor in the toilet even when using a toilet without an intake port.
The toilet seat 5 has a hollow tubular structure and is connected to the exhaust port 1 by an exhaust pipe 7 to substantially extend the odor exhaust port 1 into the toilet, thereby providing a human odor. It has the same effect as installing an exhaust port below the organ,
In this example, odor is collected in the toilet and prevented from spreading to the entire toilet room. It is effective to provide the air inlet 6 in the toilet 4 itself. However, in the case of an existing toilet having no air inlet, it is economical to use the toilet seat as in the present method.
To increase the intake air amount, the exhaust auxiliary fan 8 is connected to the connecting pipe 7.
Is also effective. With this structure, the odor in the toilet bowl is exhausted from the exhaust port without diffusing into the toilet room and without reaching the olfactory organ of a person.

FIG. 3 (a) shows a toilet having no air inlet and a toilet seat, where a odor collector 9 having one or more air inlets 6 is arranged at the position of the toilet seat and a connecting pipe. 7 is an example in which the same effect as that of FIG.

The odor collector 9 is located between the toilet 4 and the toilet seat, has a hollow structure, and uses a polymer compound such as vinyl chloride which does not deteriorate due to odor, a metal such as stainless steel which does not corrode, ceramics and the like. .

Another example of the odor collector 9 will be described below. FIG. 3 (b) is similar to the toilet seat having the air inlet shown in FIG. 2 and has the shape of the upper part of the toilet and has a hollow tube structure. 4 The odor in the peripheral area is collected by the intake port 6 without being diffused to the outside, is guided to the exhaust port 1, and has the same effect as that of providing the exhaust port below the human olfactory organ.

FIG. 3 (c) has a structure in which it is installed at the base of the toilet 4 and air is taken in from the base. In addition, in the toilet seat,

Shows an example in which the odor collector 9 can be installed. In this case, unlike the case where it is installed above the toilet 4 shown in FIG. 3 (d), the portion of the odor collector 9 at the position of the toilet seat 5 is joined to the toilet seat 5, and by using a flexible tube, It is also useful to have a structure that moves with the toilet seat 5 up and down.

FIG. 3E shows an example in which the pipe connected to the exhaust pipe 7 is bent at a right angle, and the intake hole 6 is provided inside the toilet to improve the efficiency of odor collection.

FIG. 4 shows that when the exhaust port 1 is already arranged on the ceiling or the like, the other port of the exhaust pipe 7 connected to the exhaust port 1 is arranged at a level near the toilet 4 so that the exhaust port 1 is This is an example in which the level of the human olfactory organ is set to A or lower. Ceiling exhaust port 1
In addition, for example, the exhaust pipe 7 is fixed and hermetically sealed by an exhaust port adapter 11 as shown in FIG. 5, so that all the intake air is made from the other end of the exhaust pipe. Also in this case, as described above, it is desirable that the position of the air inlet 3 be vertically opposite to the toilet 4, that is, higher than A.

FIG. 6 shows an example used for a simple flush toilet. Immediately, the discharge port of the urine and urine also serves as the exhaust port 1 of the odor. As shown in FIG. 6 (a), the conventional toilet has an outlet closed by an outlet lid 12, and during urination,
It does not have a function as the intake port 1, and the odor fills the toilet room. In (b) of FIG. 6 according to the present invention, the air inlet 6 is provided in the outlet lid 12, and the odor is always
3 and is discharged out of the toilet by the exhaust fan 2 provided in the toilet 13. A gap may be provided between the discharge port of the stool and the discharge port lid 12 without providing the intake port 6 in the discharge port lid 12. Although the same effect can be obtained by providing the intake port 1 near the discharge port of the toilet 4, remodeling of the toilet bowl is expensive and cannot be applied to an existing toilet.
