BACKGROUND ART It is common to use water stored in a storage tank of a toilet bowl to wash the toilet bowl and keep it clean. However, since the water supplied to the storage tank is stagnant for a long time, there is a concern about bacterial propagation due to contamination inside the storage tank.

Practically, fungi, etc. generated inside the toilet penetrate into the storage tank, and when the lid of the storage tank is opened, a large amount of mold and the like is frequently contaminated inside the storage tank.

Due to this problem, conventionally, a product has been released that cleans the toilet bowl by putting the toilet bowl cleaner including the cleaning fluid inside the storage tank and mixing the toilet bowl while the cleaning fluid is diffused into the water in the toilet bowl. There was a problem that the washing effect gradually decreased as the amount decreased as time passed.

In addition, since the components of the remaining detergent remain inside the storage tank, smooth cleaning is not performed, and there is also a problem of secondary contamination, so the demand for it is gradually decreasing in recent years.

In order to solve these disadvantages, a plan to supply a liquid cleaning liquid rather than a solid form was promoted, but there was a problem in that liquid cleaning liquid had to be supplied frequently, and the cleaning liquid was supplied irregularly rather than discharged in a certain amount due to a decrease in durability, resulting in wastage of the cleaning liquid. .

8 and 9 are flowcharts according to the control method of the toilet bowl washing water supply device according to an embodiment of the present invention. The toilet bowl flushing water supply device according to the present embodiment refers to FIGS. 1 to 7 .

The control module 500 can generate ozone water by generating ozone in the ozone generator 300 (S810).

The control module 500 may determine whether the ozone sensor 140 detects ozone (S814). When ozone is detected, the control module 500 may stop an operation related to generating ozone water (S842). Or you can shut off the power. If necessary, the control module 500 may warn a manager (user) that ozone is emitted to the outside through the communication unit 510 (S846).

If ozone is not detected, the control module 500 may determine whether the water level sensor 150 detects no water (S818).

When the absence of water is detected, the control module 500 may stop generating ozone water (S834).

If the ozone sensor 140 detects the presence of water while the ozone water generation operation is stopped (S838), the control module 500 may generate ozonated water (S810).

When water is sensed by the water level sensor 150, the control module 500 may maintain the ozone water generating operation for a first time period t1 (S822). The first time t1 is preferably 5 to 10 minutes.

When the operating time t1 elapses, the control module 500 may stop the ozone water generation operation (S826). The control module 500 may generate ozonated water again after stopping the ozone water generating operation for the idle time t2 (S830).

Through this, ozone water can be generated for a certain period of time at regular intervals. This is because if insoluble ozone is mixed with water for too long, it may be discharged into the air without dissolving, so that long-term or continuous production of ozone water is unnecessary. Since ozone dissolved in water disappears due to decomposition into oxygen after a certain period of time, it is necessary to periodically generate ozone water.

In general, the initial idle time t2 of the activity time zone may be set to one of 20 to 30 minutes. The idle time t2 follows a preset policy and may vary according to circumstances. For a detailed description of this, refer to FIG. 9 .

The previous idle time t2 may be an initially set value, a value input by a user, or a value set in the previous step.

Referring to FIG. 9 , the control module 500 may determine whether the current time is a time zone in which a toilet user is active and a late-night time zone (S850 and S858).

The control module 500 may set the idle time t2 to a first time T1 in an active time period, a second time T2 in an inactive time period, and/or a third time T3 in a late night time period. there is. It is preferable that the length increases from the first to the third time. The third time period T3 is set to the time until the next activity time period, so that operation may be completely stopped during the late night time.

When the no-water cycle detected by the water level sensor 150 is shorter than the preset 0th time T0, the control module 500 shortens the length of the idle time t2 (S874), thereby shortening the ozone water generation cycle. can do it faster When the water absence detection period becomes longer, the control module 500 may lengthen the idle time t2 longer.
