Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a non-flushing toilet device, and more particularly to a non-flushing toilet device in which a toilet outlet is open and communicates directly above a human waste collection chamber under the floor.

Conventional pump-type, non-flushing devices of this type include a general type that is directly connected to a toilet tank, and a type known as a well-known odorless toilet.

The present invention relates to a combination of a seated toilet element that can be used in both types and a human waste guiding element that extends below the toilet outlet.

Conventional non-flush sitting toilets are as specified by JIS, and Figures 8 to 10 show sitting toilets that are JIS standard products. It is trunk-shaped and has a large opening that is slightly smaller than the opening at the seat surface. In this conventional seated toilet, if the stool is normal, it falls without staining the inside surface of the toilet bowl, but if the stool is soft or has diarrhea, it scatters widely as it falls, so the inside surface of the toilet bowl is covered. The bottom part was dirty and the toilet bowl was deep, making it difficult to clean.

In addition, when the lower toilet tank is the oldest type of toilet bowl, only the toilet bowl gets dirty, but when the toilet tank is sealed and connected to the toilet tank with a human waste guide pipe, or when it is connected to an odorless toilet, Since PVC pipes with a maximum diameter of about 200 mm are used, the diameter must be made thinner at the bottom of the toilet outlet (usually a diameter-reducing pipe called a spat is used). The inner surface of the tube was so dirty that it was almost impossible to clean it. Furthermore, since the conventional non-flush seat toilet bowl has a wide upper opening surface, a large amount of light enters the toilet bowl, and dirt at the lower part cannot be avoided. Moreover, because the inside surface of the toilet bowl is almost vertical, even if a simple spout was installed at the top of the toilet bowl to flush out cleaning water, the water would not flow.

On the other hand, the odorless toilet type uses a ventilator to draw in outside air from the toilet opening to prevent odors from rising from the opening. The communication pipe that connects the mouth and the odor storage pipe has the same diameter as the outside diameter of the wide-area toilet opening, and is directly attached directly to the lower edge of the wide-area opening. Not only is the tube wide, but the urine that flows inside the tube adheres to it and remains, drying and discoloring it to a whitish color, making it difficult for light to enter and reflect (Figure 11).
It is extremely unpleasant to be forced to see not only the human waste in the human waste collection chamber but also the dirty surfaces inside the tube. There was even a risk of children falling.

The present invention solves the above problems and proposes an innovative device.

The drawing shows an embodiment adopted for an odorless toilet type, and the specific example will be explained in detail below.

The seated toilet bowl 1 is connected to a toilet tank from a toilet opening 2 through an odor storage pipe 7 to which an odor pipe 5 having a blindfold pipe 3 and a ventilator 6 (to be described later) is connected, and a roughly J-shaped defecation pipe 8 having a waste urine storage chamber c. 9, this seated toilet bowl 1
is the toilet opening part 2 from the upper edge surface 1a to the bottom of the ball surface 1b.
The height L to the edge is set to about 250 mm to 150 mm, and the toilet drop opening 2 is brought very close to the upper edge surface 1a, and the open surface of the toilet opening 2 is shaped like an ellipse with the long side running along the front and back. , circular shape such as a perfect circle, and approximately 17662 ~
Formed in a narrow opening area within 5024mm ² . Further, the desirable height L of the toilet bowl 1 is 200 mm, and
The desirable narrow opening area of the toilet opening 2 is the long side L ₁ 130 when the opening surface is elliptical (Fig. 3).
mm, diameter area of short side L ₂ 100 mm, perfect circular shape (4th
Figure) shows the diameter area of aperture L ₃ 100mm. This opening area has a diameter of 80 to 80 mm regardless of the open surface shape.
Form within a value of around 150mm or less to create a narrow open surface. Furthermore, a water supply nozzle 14 for cleaning water connected to a water supply pipe 15 is provided on the side surface of the ball surface 1b of the toilet bowl 1.

The blind tube 3 has a diameter suitably larger than the diameter of the outer circumferential surface 2a of the toilet port 2, specifically, a virtual pipe-shaped area a descending vertically from the outer circumferential surface 2a into the tube, and an inner human waste fall space A. A cylindrical shape with a length of 300 to 600 mm (preferably 400 to 500 mm) or a rounded cylindrical shape (5
(Fig.), and the entire inner surface 3a is colored matte black or the like to form a dark-colored light-absorbing surface b. Further, the cross-sectional shape of the blind tube 3 is formed into a perfect oval shape similar to the open surface shape of the toilet outlet 2. This blind tube 3 has an upper tube opening positioned approximately concentrically with the joint surface 10 around the toilet outlet 2 and in close contact with the opening via a packing 11, and is also tightly sealed with the odor storage tube 7 via a packing 12. Connect and connect.

As a result, the seated toilet bowl 1 has a toilet opening 2 of approximately
A narrow opening area within 17,662 to 5,024 mm ² and extremely close to the human body, that is, the upper edge surface 1a, approximately 250 mm or less,
A wide-end falling parabola drawn by solid defecation (Figure 6)
It is located above the cross-sectional area _A1 within the range A, and the solid waste excreted from the human body can pass through the stool opening 2 without touching it within the range where there is little movement in the front, back, left, and right directions. Blindfold tube 3 without staining the mouth surface
to fall. In addition, the toilet opening part 2 has a narrow opening area.
This significantly reduces the viewing angle area and also narrows the incident angle of light, thereby making it difficult to see the aforementioned viewing angle area, that is, the inside of the blindfold tube 3 and especially the inside of the human waste storage chamber c. In addition, the opening area is similar to the odor tube 5 with a diameter of 100 mm or less in terms of its opening area, ensuring almost the same amount of ventilation, and the intake force by the ventilator 6 is the only inlet for outside air. It generates airflow that is 100% effective without being reduced in a certain fecal evacuation port 2 and does not allow odor to dissipate or leak during defecation. Since the width is less than a fraction of 100 mm, there is no problem of insufficient air intake from the toilet outlet on the wide open surface, causing odor to rise and leak. In addition, when the user becomes unwell, the toilet 16 can be opened to cover the falling range of fecal matter that spreads and falls to the fecal drop opening 2 and the ball surface 1b around it, and can be cleaned by rinsing each time. It is.

The blind pipe 3 penetrates the floor 4 to communicate the toilet outlet 2 and the odor storage pipe 7, and has a pipe-shaped imaginary area a descending vertically from the outer circumferential surface 2a of the toilet outlet 2 in the pipe. As a boundary, an inner human waste falling space A and an outer human waste falling space B coexist, and the human waste falling from the toilet opening 2 is moved by gravity to the inner dedicated passage surrounded by the human waste falling space B, that is, the human waste falling. It falls vertically in the space A and settles on the bottom of the defecation pipe 8, and the dark-colored light-absorbing surface b is not contaminated by the falling excrement, absorbing the light that enters from the feces drop opening 2 and darkening the inside of the pipe. It is possible to hide the human waste and the like that settles in the defecation pipe 8 so that they cannot be seen from the defecation outlet part 2. Therefore, in the conventional odorless toilet device, there is the discomfort of being able to see human waste, and furthermore, the discomfort that the communicating pipe that is directly connected to the toilet outlet and hanging down becomes dirty with urine flowing from the opening and turns white and becomes exposed. In addition, the unpleasant odor caused by urine deposited in the tube is eliminated.

Furthermore, in the embodiment shown in FIGS. 1 to 3, in which the narrow open surface of the feces drop opening 2 has an elliptical shape that is long in the front and back, the falling area of fecal solids is larger in the front and back than in the left and right sides. The horizontal width of the visual surface area can be narrowed.

In the above embodiment, the blind tube 3 may be directly connected to the human waste storage chamber c of the toilet tank, and the gist of the present invention is not changed in any way.

As described above, the present invention provides for the toilet bowl to have a toilet opening at a position of approximately 250 to 150 mm relative to the human body side, that is, the upper edge surface, which has a narrow cross-sectional area within the range of the wide-falling falling parabola drawn by defecated solids. By making the openings as close as possible, the opening area of the opening can be narrowed to within the allowable maximum of about 17,662 to 5,024 mm ² , making it a narrow open surface. As a result, the solid waste passes through the fecal evacuation port without touching it while there is little movement back and forth, left and right, so there is no staining at all, which is good. The stool opening, which is a narrow open surface, significantly reduces the visual surface area and also narrows the incident angle of light, thereby making it difficult to see the inside of the visual surface area, that is, the blind tube and the human urine storage chamber, and darken it. Therefore, the dissatisfaction of being forced to see undesirable human waste and the like is resolved, and the user can use the device comfortably without any visual discomfort. At the same time, the space in which the odor rises is narrow, and the amount of odor emitted is also reduced. Specifically, as a result of experiments using an 8W electric fan within the household economic power consumption range and an ordinary odorless toilet tank device, we found that the wind speed at the odor trap opening of a stink pipe with an outer diameter of 80 mm and an inner diameter of 77 mm. is (average of 4 measurements with thermocouple anemometer)
Although it is 1.2m/sec and the air volume is 335 per minute,
In a conventional toilet bowl (JIS standard product, elliptical with an inner diameter of 307 x 200 mm), the diameter of the toilet outlet is approximately 13 times the diameter of the odor pipe, and the average wind speed is 0.15 m/sec. At the center of the toilet opening, only 0 to -0.1m/sec was obtained, and even in field tests in the toilet tank, when a large amount of volatile gases such as ammonia were generated, the odor could not resist the rising force of the volatile gases and the odor flowed back. However, according to the present invention (the toilet outlet is
(130 mm, short axis 100 mm oval), the average wind speed at the toilet outlet was 0.9 m/sec, and there was no backflow of odors at all.
Moreover, since the air flows quickly along the bottom of the ball, there is no smell of urine attached to the bottom of the ball.
You won't have to smell your own stool odor when defecating,
Odor problems are also eliminated.

In addition, a human waste fall space and a human waste waste fall space located in a surrounding manner are formed inside the blindfold tube, so that the human waste water that falls by gravity from the toilet opening is transferred to a dedicated human waste fall space. passing through space,
Due to the presence of the excess human waste drainage space, the inner surface of the tube was not soiled at all, and the discomfort caused by the visual recognition of adhering human waste and the like in the past, as well as the odor caused by the adhering human waste, were eliminated and the tube was comfortable. In addition, the blind tube makes the interior of the human waste collection chamber visible through the fecal drainage opening appear narrow in the form of a spot, thereby hiding the human waste from view.

Furthermore, for the surface area where fecal solids spread out and fall, there is a feces drop opening with a narrow open surface at the top, and a blindfold tube with a large feces/urine drainage space below this. As a result, it was possible to prevent the adhesion of human waste and meet the above-mentioned effects. In addition, the toilet outlet and the ball surface around it, which get dirty when you feel unwell, can be easily cleaned by supplying cleaning water from the water supply nozzle each time. They are equally comfortable and useful.
