Description

[Detailed description of the invention] [Industrial application field] This invention is a toilet structure that allows smooth and reliable removal and washing of excrement in a Western-style toilet, saves on the washing water used, and prevents the generation of foul odors. Pertaining to disclosure.

[Prior Art] In conventional Western toilets of this type, the toilet main body and the toilet bowl portion are integrally molded. In addition, these Western toilets, especially Western toilets of the type that receive excrement in a tray, have a tray that rotates in the same direction as the direction in which excrement falls, and also rotates from the top opening of the toilet toward the excrement discharge port. Washing water flows out in a straight line.

[Problems to be solved by the invention] Therefore, even if either the toilet main body or the toilet bowl section breaks down, it is necessary to replace them all, which increases repair costs and other costs.
In addition, the tray may be slightly loosened due to the weight of falling excrement, and a large amount of washing water is required to wash the entire inner surface of the toilet bowl.

[Purpose of the invention and means for solving the problems] The toilet structure according to the invention allows for easy repair in the event of a breakdown, and particularly limits the movement of the saucer in such Western toilets, thereby preventing unexpected damage to the saucer. In order to prevent the release of excrement and ensure reliable removal of excrement, cleaning, and effective use of cleaning liquid, the toilet bowl 1 has an open top opening and a funnel-shaped excrement outlet.
A Western toilet consisting of a top-opening toilet portion 2 having an outwardly projecting flange supported on the opening edge of the main body, and a flush lever 7 is provided on the upper side of the toilet main body 1, A winnow-shaped saucer 6 having a recess for storing treated water is integrally suspended on the rotating shaft of the flushing lever 7 by a support rod 6a, and a lever for opening and closing the flushing water supply ball valve is connected. A flushing water discharge nozzle 4 is provided inside the upper part of the rear side of the toilet bowl section 2, and the flushing water discharged from this discharge nozzle 4 spirals around the inner circumferential wall of the toilet bowl section 2. A step edge for cleaning is provided from the opening of the discharge nozzle 4 toward the lower part of the toilet bowl part 2, and the tray 6 is provided between the mouth end of the excrement discharge port of the toilet bowl part 2. The excrement outlet is configured to be able to swing forward and backward downwardly with a predetermined interval left, and the mouth end of the excrement outlet is always buried in the treated water in the recess of the receiving tray 6. At the same time, when the tray 6 is swung by the flush lever, the tray 6 is swung from below the excrement outlet toward the upper rear side of the excrement outlet, and the tray 6 is tilted. This provides a Western-style toilet structure.

[Example] A typical example of the Western toilet structure according to this invention will be described below with reference to the attached drawings. 1 is a toilet main body constituting the toilet, 2 is a support on the opening edge of the toilet main body 1. This toilet bowl part 2 is shown.
has an outwardly projecting flange and is open at the top. Reference numeral 3 indicates a piping space cover for supplying washing water to the upper discharge nozzle 4 of the toilet bowl section 2.

The toilet main body 1 has generally the same structure as a conventional toilet holder frame, is installed on the piping space leading to the toilet tank, and has openings in its upper and lower parts that communicate with each other.

A toilet part 2 having a generally funnel-shaped excrement outlet 5 is inserted onto the toilet main body 1 so that the upper flange 2a of the toilet part 2 is supported by the upper edge of the opening of the toilet main body 1. , and a saucer 6 is attached to the lower edge 5a of the opening of the excrement discharge port 5 in the toilet bowl portion 2 with a predetermined gap therebetween.

The saucer 6 is generally winnow-shaped, and the lower edge 5a of the discharge port 5 is buried within the rising dimension of the saucer 6, that is, within the washing water of the saucer 6. Arms 6 provided on both sides
a is integrally attached to the shaft of the flash lever 7,
By operating the flash lever 7, the saucer 6, which is generally horizontal to the discharge port 5, is expanded downward and moved from below the discharge port 5 to the upper rear side of the discharge port 5, as vertically as possible. It is designed to be able to swing freely in any direction.

The flush lever 7 is elastically pulled by a spring 10 whose one end is connected to an opening/closing operation lever 9 of a cleaning water supply ball valve 8 so that the saucer 6 is always located in a horizontal position.

Next, pressure water supplied from the tank 11 (it is also possible to omit the tank and connect directly to the water pipe to utilize water pressure) is used to supply flushing water to the discharge nozzle 4 of the toilet bowl part 2. The opening and closing of the valve 8 is controlled and supplied by connecting a rod 12 connected to the flash lever 7 and a spring 10 to the lever 9 of the valve 8, and using the spring 10 to always urge the lever 9 in the valve closing direction. At the same time as pulling
By pushing the rod 12 against the elastic force of the spring 10, the valve 8 and the saucer 6 are opened simultaneously.

The cleaning water thus supplied to the discharge nozzle 4 is
The discharge nozzle 4 is wound gradually downwardly on the inner upper circumferential surface of the toilet bowl part 2, and the discharge nozzle is supplied and discharged to a step edge 13 which is provided in a circumferential manner so as to gradually narrow the step width. did.

Due to the configuration of the step edge 13, the cleaning water discharged from the discharge nozzle 4 falls from the step edge 13 along the inner circumferential surface of the toilet bowl portion 2 as the supply pressure gradually decreases and the step width decreases. The attached dirt is removed and the dirt is flushed down into the sewage tank from the discharge port 5 which has already been opened.

The tray 6 is expanded before the washing water is emitted, and the excrement supported by the tray 6 falls and is removed together with the washing water collected in the tray 6. , the dirt attached to the saucer 6 is
It was removed using this radiation washing water.

In addition, since the closing of the valve 8 and the closing of the saucer 6 are performed simultaneously by the flush lever 7, even after the saucer 6 is closed, sufficient washing water is supplied to fill the saucer 6, and the minnow can be washed. The lower edge 5a of the discharge port 5 is filled with washing water into the shaped saucer 6.
By burying it in this water, the backflow of foul odors was reliably suppressed. In particular, since a predetermined gap is provided between the saucer 6 and the lower edge 5a, and the saucer 6 is prepared separately from the discharge port 5, dirt can be collected between the saucer 6 and the discharge port 5. This product did not cause any stickiness, and the fear of foul odor generation with continued use was completely eliminated.

[Effects of the invention] The Western toilet structure according to this invention is expected to have specific effects on the above-mentioned characteristics due to the characteristic structure described above. That is, since the toilet bowl main body 1 and the toilet bowl part 2 are molded separately, even if a failure occurs that requires replacing the toilet bowl, since the container is manufactured, there is no need to replace the entire toilet bowl, and the toilet bowl body 1 or By replacing the toilet bowl part 2, it can be repaired, and costs such as repair costs can be reduced. Furthermore, the toilet main body 1 and the toilet bowl part 2 can be combined and converted with other toilet main bodies 1 and toilet parts 2, respectively, and a wide variety of Western toilet bowls can be provided.

Further, the tray 6 is swung from the lower end of the excrement outlet 5 toward the upper rear side of the excrement outlet 5.
Since the tray 6 is tilted, the direction in which the tray 6 swings and the direction in which the excreta falls are not the same but perpendicular, and there is no possibility that the tray 6 will be released unexpectedly.

Furthermore, since the supplied cleaning water is dissipated along the unique step edge 13, the cleaning water discharged from the discharge nozzle 4 washes the inner circumferential wall of the toilet bowl portion 2 in a spiral pattern, resulting in inconveniences such as clogging of the discharge nozzle. In addition, the flushing water can be evenly guided to the inner wall surface of the toilet bowl without reducing the radiation pressure, and reliable flushing can be achieved with a small amount of water.
