Description

[Detailed description of the invention] [Industrial field of application] This invention relates to the improvement of flush toilet bowls.

[Prior art and its problems] In the past, excrement adhered to the inner wall of the toilet bowl after using the toilet, and flushing water was flushed many times to wash it away, and a considerable amount of water was used for one use. are using.

In addition to the use of water, there are also problems from a hygienic standpoint, such as the fact that after a certain period of time, the inner walls of the toilet bowl become covered with water scale, which causes problems in appearance and becomes a source of bad odors.

There are also toilets that use a pump to reuse or discharge the water stored in the water storage section to the outside (for example, Utility Model Application No. 58-94772, Japanese Patent Application No. 61
-Refer to No. 233839).

However, this type of toilet bowl does not have a detection means for detecting whether or not there is solid matter in the water storage section, and regardless of whether there is solid matter in the water storage section,
Since the system reuses stored water or discharges it to the outside, there is a risk that contaminated water may be circulated or that the circulation or discharge pump may be damaged.

This idea was made in view of the above circumstances,
To provide a toilet bowl for flushing that saves water and keeps the inner wall of the toilet clean at all times and is excellent from a hygienic standpoint.

[Means for Solving the Problems] The flush toilet bowl according to this invention is provided with a sensor that detects the presence of solid matter in the water storage portion on the inner wall of the water storage portion that stores accumulated water in the flush toilet bowl. A water passage with a water discharge hole for discharging water into the inner wall surface is formed on the upper peripheral edge of the inner wall of the toilet bowl, and a pump is installed outside the inner wall of the toilet that communicates with the water reservoir and the water passage, and detects the absence of solid matter in the water reservoir. The sensor is activated to drive the pump, and the accumulated water in the water storage section is sent to the passageway, and the water is discharged from the water discharge hole onto the inner wall of the toilet bowl.

[Example] Hereinafter, an example of the flush toilet bowl according to this invention will be described with reference to the drawings. Reference numeral 1 in the figure is the toilet bowl body.

The toilet main body 1 is a Western-style seated toilet, and a water storage part 2 for storing standing water W flowing out from a tank T is formed at the bottom.

Further, the water storage portion 2 is divided into two by a partition wall 3 vertically installed from the front wall 1a of the toilet main body 1 to form a trap, and a drainage portion 4 on the front wall 1a side is formed in the water storage portion 2, and this drainage The portion 4 communicates with the drainage channel 5 side.

Further, the rear wall 2a of the water storage section 2 and the rear wall 2
An upper optical sensor 6 is disposed on the partition wall 3 facing a, slightly below the level of the accumulated water W.

The upper optical sensor 6 is for sensing solid objects such as excrement and absorbent cotton floating in the water level of the accumulated water W, and is connected to a light emitting element 6a such as a light emitting diode provided on the partition wall 3 and the water storage section 2.
It consists of a light receiving element 6b such as a phototransistor or photodiode provided on the rear wall 2a.

Further, a lower optical sensor 7 is disposed slightly above the bottom surface of the water storage section 2 .

The lower optical sensor 7 is for sensing solid matter on the bottom surface of the water storage section 2, and similarly to the upper optical sensor 6, it has a light emitting element 7a provided on the bottom front wall 2b side of the water storage section 2 and a light emitting element 7a provided thereon. Facing rear wall 2a
It consists of a light receiving element 7b provided on the side.

In addition to the water passageway from the tank T, there is also a water passageway 8 formed of a pipe on the upper periphery of the inner wall of the toilet main body 1.
A toilet main body 1 is installed in this water passage 8.
A plurality of water discharge holes 8a are formed for discharging water onto the inner wall surface.

A pump P is disposed outside the inner wall of the toilet main body 1 and is connected to the water storage portion 2 via a pipe 9 and to the water passage 8 via a pipe 10.

Further, the pump P is electrically connected to the upper optical sensor 6 and the lower optical sensor 7 via a control device C and a motor M.

Further, a lid 11 is attached to the rear wall 1b side of the upper peripheral edge of the toilet main body 1 by a hinge 11a, and a switch 12 is attached to the hinge 11a.

The switch 12 is connected to the control device C and is set to be turned on when the lid 11 is closed and turned off when the lid 11 is opened.

The pump P operates when the lid body 11 is in a closed state and there is no solid matter near the water level of the accumulated water W or near the bottom of the water storage section 2, that is, when both the upper optical sensor 6 and the lower optical sensor 7 detect solid matter. It is activated by the control device C only when it does not sense the
The accumulated water W in the water storage section 2 is discharged from the water discharge hole 8a of the water passage 8 via the pipe 9 and the pipe 10.

Therefore, when the lid 11 is in an open state,
Even if the pump P is in the closed state, the pump P will not operate if solid matter is present in the water storage section 2.

According to the flush toilet bowl of the above embodiment, after flushing, flushing water is flushed from the tank T, solids are flushed away, and the lid 11 is closed. The water is sent to the water passage 8 through the water passageway 8 and discharged from the water discharge hole 8a, and the accumulated water W is constantly circulated when the lid 11 is closed, so that even if there is excrement or other deposits on the inner wall of the toilet main body 1, it is not a problem. When used, it is washed cleanly and does not attract water scale, reducing the number of times it needs to be cleaned. Moreover, it always maintains a clean state in terms of hygiene and appearance.

In addition, since accumulated water W is used and circulated, water can be saved and it is economical.

In addition, if solid matter is present in the water storage section 2,
Since the pump P does not operate due to the detection by the upper and lower optical sensors 6 and 7, solid matter does not flow inside the pump P or the water passage 8, which may cause the inside of the water storage section 2 to become polluted or malfunction of equipment, etc. Nor.

Furthermore, since the pump P does not operate when the lid 11 is open, the accumulated water W does not circulate during the errand, so that no harm to the pump P or the like occurs.

Although the optical sensors 6 and 7 are provided above and below the water storage section 2, the optical sensors may be provided at either one or at an intermediate position in the height direction of the water storage section 2.

Furthermore, instead of the optical sensors 6 and 7, a biosensor or the like may be used to sense when water with a concentration of uric acid or the like remains, and to control the operation of the pump P.

In addition, the circulation of accumulated water W washes away the deposits on the inner wall of the toilet bowl body 1 into the water storage part, and when small pieces of excrement become floating to some extent, the pump P is activated by detection by the optical sensors 6 and 7. It can also be controlled to stop.

Further, the operation of the pump P may be limited to a predetermined period of time, such as 10 minutes, after the lid 11 is closed.

Furthermore, a filter or the like can be attached to the tip of the tube 9 to prevent dirt and other substances from entering the pump P.

Further, this flushing toilet bowl is not limited to Western or Japanese style toilet bowls, but can be applied to any type of toilet bowl that has a storage section for standing water.

[Effects of the invention] As explained above, the flush toilet bowl according to the present invention is provided with a sensor that detects the presence of solid matter in the water storage part on the inner wall of the water storage part that stores accumulated water in the flush toilet bowl. A water passage with a water discharge hole is formed on the upper peripheral edge of the inner wall of the toilet bowl, and a pump is provided outside the inner wall of the toilet that communicates with the water reservoir and the water passage, and detects the absence of solid matter in the water reservoir. The system is configured so that the pump is activated by the operation of the sensor, and the accumulated water in the water storage part is sent to the water passage, and then the water is discharged from the water discharge hole on the inner wall of the toilet bowl.The flushing water can be flushed after using the toilet, and if there is no solid matter in the water storage part. Since the accumulated water in the water storage section is circulated by the pump,
The accumulated water constantly washes away excrement, etc. adhering to the inner walls of the toilet bowl, etc., and the inner walls of the toilet bowl are kept clean as limescale etc. do not adhere to the toilet bowl, and since accumulated water is used and circulated, it helps save water and is economical. .

In addition, the sensor detects that there is no solid matter in the water storage area, and the pump can only be operated in this case, so the circulating standing water will not become contaminated and will not cause any harm to the pump or other equipment. It produces an effect such as "nothing".
