Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a urinal cleaning mechanism.

[0002]

2. Description of the Related Art In a conventional urinal, merely flushing water after use by a person gradually causes water scale or slime to adhere to the urinal, and odor is generated. In addition, urine stones adhere to the inside of the pipe to narrow the passage of sewage, or adhere to the surface of the toilet to impair the appearance, and serve as a breeding ground for bacteria and emit odor. In particular, the trap shield constituting the trap section is
It is installed to prevent garbage such as cigarettes and gums from entering the trap portion, but receives urine directly and is usually in the air and dried, so that odorous urine stones are easily formed.
Urinary stones that have once adhered cannot be removed unless they are strongly rubbed with a brush. In addition, it is necessary to ask a specialized contractor to remove uroliths that can be formed in drainage pipes, which is a heavy burden.

[0003]

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and prevents urine stones from adhering to the urinal trap and the generation of offensive odor. Another object of the present invention is to provide a urinal cleaning system that suppresses urine stone adhesion.

[0004]

To achieve the above object, the present invention provides a urinal, a water supply passage for supplying flush water to the urinal, a control device for controlling water supply,
In the urinal cleaning system including a shield covering the trap unit from above, a water level of the trap unit is higher than an upper surface of the shield.

[0005] Urinary stones, which cause an unpleasant odor, are composed of poorly soluble crystals formed by binding of phosphate ions contained in urine and calcium. Since the formation of these crystals is promoted under drying, the present invention suppresses the generation of urine stone that can be used as a trap shield by completely submerging the trap portion.

Further, the present invention is characterized in that a sterilizing water supply device for mixing a sterilizing component into the washing water is provided.

[0007] The metabolic activity of bacteria is involved in the production of the urinary stone. Bacteria enter the trap from urine and air,
By shifting the pH of the trap water to the alkaline side due to metabolism of the bacteria, phosphoric acid crystals, which are urinary stones, are easily formed.
Once formed, uroliths have a high porosity, which makes it easier for bacteria to settle down and further accelerates urolith formation. In the present invention, a urinal that is hardly soiled and does not smell can be achieved by sterilizing bacteria that play a part of the uric stone production cycle.

Further, the present invention is characterized in that urinal flush water is spouted at predetermined time intervals.

Normally, washing water is spouted to wash out urine with human use. At that time, 100% urine is not excreted, and the slightly remaining urine becomes a breeding source of bacteria and a component of urinary stone. The present invention performs the spouting of the washing water regardless of the use of a person at predetermined time intervals,
The remaining urine and propagated bacteria are discharged from the trap section.

Further, the present invention is characterized in that urinal flush water is discharged at night.

[0011] The urinary stones are more likely to form when the use of humans is interrupted and the trap water stays for a long time. Therefore, nighttime when human use is interrupted is the time when urinary stones are most likely to be generated. Therefore, urine stones can be effectively suppressed by flushing water at night.

Further, the present invention is characterized in that the sterilizing water supply device operates simultaneously with the periodic discharge of the washing water including at night. By flowing sterilizing water, the bacteria are completely killed in addition to the discharge of dirt, so that the urinary stone control effect is increased.

Further, the present invention is characterized in that the sterilizing water supply device generates silver ions by electrolysis.

Silver is conventionally known to have bactericidal properties and is a metal used in various fields. Among the metal ions, it has the strongest bactericidal activity and has a broad antibacterial spectrum, so it has a bactericidal effect on many bacteria. Also, silver is effective at very low concentrations,
In use, the electric energy for generating silver ions is small.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In order to further clarify the operation and effect of the present invention described above, preferred embodiments of the present invention will be described below.

FIG. 1 shows a first embodiment of the present invention. The urinal 1 has a ball surface 2, a trap portion 3, and a shield 4 for preventing foreign substances such as cigarettes from entering the trap portion as constituent elements, and is further connected to a drain pipe 5. The shield 4 is submerged in trap water. Even when submerged, foreign substances can be prevented from entering the inside of the trap, so that the original function can be secured. Further, the ratio of submergence may be such that the upper surface of the shield 4 is hidden by water, and there is no problem of splashing of water when used by a person. As a result, the surface that comes into contact with the water air comes above the shield 4, so that the dirt on the draft surface becomes the bottom of the ball surface 2 and cleaning becomes easier.

FIG. 2 shows a second embodiment of the present invention. FIG.
, A silver electrode section 9 is provided downstream of a water supply valve 7 such as a flash valve provided in the water supply pipe 8. The water supply valve 7 is electrically connected to a known cleaning control device 6, and the water supply pipe 8 is connected to the urinal 1.

Next, the operation will be described. After the user uses the urinal 1, the water supply valve 7 is opened by the operation of the cleaning control device 6, and the cleaning water flows to the urinal through the water supply pipe 8. The flushing form of a general urinal is that the toilet flush water containing no silver ions is supplied to the urinal 1 as it is. On the other hand, in the embodiment of the present invention, the electric energy of the power supply unit 11 is supplied to the pair of electrodes 10a and 10b in the silver electrode unit 9 via the electrolysis control device 12, and one of the electrodes 10a and 10b is connected to the anode side. Silver ions are eluted from the urine, and the silver ions are supplied to the trap water of the urinal.

FIG. 3 is a flowchart showing a urinal cleaning system according to a third embodiment of the present invention, in which periodic sterilization water, in this embodiment, silver ion water is discharged.

When the use of the urinal 1 is detected by the human body sensor, flush water for flushing urine from the ball surface 2 and the trap portion 3 flows through the water supply pipe 8. Thereafter, if the use of the person is not performed for Ta time, the cleaning control device 6 is operated, and at the same time, the electrolysis control device 12 is synchronized to energize the silver electrode unit 9 so that the silver ions are converted to the silver electrodes 10a and 10b.
Washing water containing silver ions eluted from the positive electrode of the urinal 1
Flows to Since the cleaning control device 6 and the electrolysis control device 12 are electronic components, they can be made identical. If the above-mentioned Ta is set within 6 hours by a timer incorporated therein, the nighttime water discharge is always performed. In addition, the water discharge time can be set using the time measurement of the timer. If only water flows without the silver electrode being electrolyzed during regular water discharge, dirt components such as organic matter in the trap section and drainpipe are removed.
Has the effect of discharging.

The polarity of the electrodes 10a and 10b (that is, the anode and the cathode) is reversed by the electrolysis controller 12 each time electrolysis is performed, thereby preventing scale such as calcium carbonate from adhering to the cathode side. At this time, the electrodes 10a and 10b are consumed with the supply of silver ions. Therefore, the time when the electrode is the anode and the time when the electrode is the cathode are made equal so that the pair of electrodes 10a and 10b are consumed evenly. The electrode 10 without waste until the end.
a and 10b can be used up. Electrodes 10a, 10
In the case of b, pure silver plate material is preferable in that it can elute silver ions from itself and thus can extend the life. However, an alloy containing silver or silver plating may be used.

[0022]

As described above, the present invention can prevent urine stones from adhering to a shield installed in a urinal trap. Furthermore, by discharging silver ion water having bactericidal power during the night time, urine stones can be prevented inside the trap and in the drain pipe.
