Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to an apparatus for cleaning a toilet bowl with ozone water, wherein the ozone water is caused to flow at least a predetermined amount after the toilet bowl is washed, and excellent effects such as cleaning and sterilization of the toilet bowl with ozone water are obtained. The present invention relates to a toilet cleaning device using ozone water.

[0002]

2. Description of the Related Art A technique for cleaning a toilet bowl using ozone water is already known, for example, from Japanese Patent Publication No. 7-56151. This known technique is as shown in FIG. That is, an air nozzle 3 is provided in a washing tank 2 for storing the washing water of the toilet bowl 1, and the ozone generated by the ozone generator 4 is supplied to the washing water in the washing tank 2 to be dissolved therein. It produces water. An ozone water supply pipe 6 for supplying ozone water in the tank to the toilet 1 is installed separately from the washing water supply pipe 5, a control valve 7 is provided in the middle thereof, and control is performed by a signal from the human body detection sensor 8. The control valve 7 is controlled to open and close via a heater 9.

When a user approaches the toilet 1, a human body detection sensor 8 detects this and opens a control valve 7 via a controller 9. As a result, the ozone water in the washing tank 2 continuously flows little by little from the ozone water supply pipe 6 to the toilet 1 side, and deodorization, sterilization, antifouling, and the like by the ozone contained in the ozone water are performed, and the user has an odor. There is no such thing as smoking. The supply of the ozone water is performed while the human body detection sensor 8 is detecting the user, so that the odor is not absorbed during the use. When the toilet is to be washed after use, the washing handle 10 is rotated and the washing valve 11 is opened to supply a large amount of washing water from the supply pipe 5 to wash the toilet.

[0004]

However, in the above-mentioned conventional toilet flushing device, ozone is blown into the flush water stored in the flush tank 2 to generate ozone water, so that the total amount of the stored water is reduced. It was necessary to make the ozone concentration of the sample not less than a predetermined value. This is because if the concentration is not higher than a predetermined ozone concentration, effects such as deodorization, sterilization, and antifouling by ozone cannot be obtained. Thus, in order to make all the stored water equal to or higher than the predetermined ozone concentration in the above-mentioned conventional toilet flushing device, it takes 6 minutes or more even in the case of a flush toilet having a capacity of 12 liters. This is because the production rate of ozone water exceeding a predetermined ozone concentration requires a lot of time because the production rate of ozone water is low in a commercially available small-sized ozone water generation apparatus, which is about 2 liters per minute. .
Therefore, if the toilet is reused immediately after using it once,
Ozone water is supplied from the supply pipe 6 to the toilet 1 before the cleaning water in the cleaning tank 2 reaches the predetermined ozone concentration, and there is a problem that the desired effects such as deodorization, sterilization, and antifouling cannot be obtained. .

In addition, it takes about 5 seconds for the flush water in the flush tank 2 to be discharged to the toilet 1 by flushing the toilet, and after the flush water is supplied, makeup water is supplied into the flush tank 2 and the flush tank 2 is discharged. It took about 45 seconds for the flush toilet with a capacity of 12 liters to recover the washing water inside to the predetermined level. Therefore, after a single toilet flush, it takes at least about 6 minutes and 50 seconds to store a predetermined amount of cleaning water in the cleaning tank 2 and make the cleaning water have a predetermined ozone concentration or more, There is a drawback that it cannot be applied to public toilets and the like used by an unspecified number of people.

In a tank of the type open to the atmosphere, such as the cleaning tank 2, the ozone water concentration is reduced by half in 3 to 4 minutes and becomes zero after 10 minutes, so that the ozone generator 4 is constantly driven. Therefore, there has been a problem of oxidative corrosion due to ozone of equipment and a problem of high electricity cost.

On the other hand, as a method of cleaning a toilet, there is a flush valve method in addition to the above-mentioned cleaning tank method. However, in this flush valve method, a cleaning device using ozone has not been developed. Met.

A nozzle capable of stirring the ozone water in 3 may be provided.

Next, the operation of the toilet bowl cleaning apparatus 12 according to the first embodiment will be described. First,
Cleaning handle 10 provided on the outer side surface of cleaning tank 2
Is rotated to lift the float valve 18 to start flushing the toilet. As a result, the washing water stored in the washing tank 2 flows through the float valve body 19 to the toilet and the toilet is washed. Then, when the water level in the cleaning tank 2 starts to decrease, the floating ball 15 is lowered, the cleaning water is supplied to the cleaning tank 2 from the water discharge port 20 of the ball tap 14, and the ozone water tank 13 is supplied through the branch pipe 21 of the ball tap 14. Cleaning water is supplied to the At this time,
The float valve 16 in the ozone water tank 13 is at a position raised from its valve seat, and the washing water in the tank 13 is
It flows out from the float valve cylinder body 19 to the toilet side via.

While the floating ball 15 of the ball tap 14 descends as the water level decreases, the float valve 16 in the ozone water tank 13 is seated on its valve seat and the washing water in the ozone water tank 13 flows out. To stop. At about the same time, the water level switch 23 detects the water level in the washing tank 2 and turns on the ozonizer 23 to generate ozone. The generated ozone is sucked by the negative pressure generated by the cleaning water flowing through the aspirator 22 and melts into the cleaning water to generate ozone water. That is, the ozonizer 23 and the aspirator 22 constitute the ozone water generator 26. In addition, the ozone concentration of the generated ozone water is a method in which ozone is blown into a small amount of cleaning water to generate the ozone water.
The concentration exceeds the concentration required for obtaining predetermined ozone effects such as deodorization and antifouling.

Next, when the water level in the washing tank 2 drops to a predetermined position, the float valve 18 is drawn in by the force of the outflowing washing water, seats on the valve seat of the float valve cylinder 19, and moves toward the toilet. Stop outflow of washing water. That is, the toilet cleaning is ended. After the float valve 18 is seated on the valve seat, the water level in the cleaning tank 2 starts to be recovered by makeup water discharged from the water discharge port 20. When the water level recovers to a predetermined level, the float valve 16 of the ozone water tank 13 linked to the movement of the floating ball 15 of the ball tap 14 comes away from its valve seat, and the ozone water stored in the ozone water tank 13 is connected to the connection pipe. It is supplied from 17 to the toilet via the float valve cylinder 19. The ozone water tank 13 is set to store a predetermined amount of ozone water. The amount of the ozone water needs to be sufficient to cover the entire rim water passage of the toilet because the entire surface of the toilet bowl needs to be cleaned. The amount of ozone water stored in the tank 13 is adjusted by adjusting the ratio of the flow rate discharged from the water discharge port 20 to the washing tank 2 and the flow rate discharged from the branch pipe 21 to the ozone water tank 13. Will be

The replenishment water stored in the ozone water tank 13 becomes ozone water by blowing ozone discharged from the air diffuser 30. When the water level in the ozone water tank 13 exceeds the partition wall of the siphon tube 31, the ozone water generates a siphon action, and is drawn in and flows out from the float valve seat cylinder 19 to the toilet. The outflow is performed after the flushing of the toilet after the float valve 18 is seated on the valve seat. Therefore, in the case of the toilet flushing device 27 as well, it is possible to wash ozone water by a predetermined flow rate to the toilet side after flushing the toilet and perform post-washing. The effect of the cleaning with the ozone water is the same as that of the first embodiment. Note that the ozone water tank 1 after the siphon action has ceased.
The ozone water remaining in the tank 3 is discharged from the drain pipe 32 through the float valve seat cylinder 19 to the toilet bowl, and the ozone water tank 13
It will not remain inside. Excess ozone not dissolved in the makeup water is self-decomposed by the decomposer in the ozone decomposer cartridge 29. For example, in the case of using a manganese _{catalyst, 2MnO 2 + 5O 3 → Mn} 2 O 7 + 6O oxidation reaction occurs, such as _2, it is decomposed into oxygen as a decomposition agent.
