The present invention relates to a suitable toilet sterilizer.
[0002]
[Prior art]
In order to operate the apparatus, there is generally a manual seesaw switch or a turn switch.
[0003]
In addition, as seen in Japanese Examined Patent Publication No. 62-28249, there is a sterilizing water spray on a toilet using a timer so that it is performed on a regular basis.
[0004]
[Problems to be solved by the invention]
The manual switch must be operated by the user each time it is used, forgetting to operate due to annoyance, and preventing sterilization water from being supplied to the toilet, so that the original purpose of preventing soil adhesion cannot be achieved. There is.
[0005]
In addition, the device described in Japanese Examined Patent Publication No. 62-28249 has a built-in device in the warm water washing toilet seat, and in order to add a sterilizing water generating function to the toilet, the toilet seat itself must be replaced, A Japanese-style toilet that does not require a toilet seat has the disadvantage that its function cannot be added.
[0006]
In addition, bacteria in flush toilets grow in toilet stagnant water used to seal the drain trap part of the toilet and become a source of odor and dirt. In addition, when sterilizing water is sprinkled at a predetermined time, but when toilet flushing is frequently performed by stool, bacteria that have been increasing in toilet staying water are discharged by toilet flushing, so that frequently There is no need to spray the sterilizing water, and the sterilizing water is sprinkled.
[0007]
The present invention enables a sterilizing water generating device to be attached regardless of the type of toilet if the toilet has a washing water reservoir, and intends to supply sterilizing water to the toilet stagnant water at an effective time.

In order to achieve the above object, in the toilet bowl sterilizing apparatus according to the present invention, when the flush water is supplied to the toilet bowl from the flush water reservoir storing the flush toilet water, and the flush water is supplied to the flush water reservoir. When the water flow is detected by the water flow detection means or the water level fluctuation of the washing water reservoir is detected by the water level detection means, and the number of times the toilet bowl is washed is counted by the detected signal, and the count value is equal to or greater than the predetermined number The sterilizing water generator is operated to generate sterilizing water, and the generated sterilizing water is allowed to flow through the toilet bowl .
[0009]
As described above, since the water flow detection means supplied to the wash water reservoir or the water level fluctuation of the wash water reservoir can be detected by the water level detection means and the sterilizing water can be automatically supplied to the toilet bowl, there is no troublesome operation. Sterilization water can be supplied to the toilet bowl.
[0010]
In addition, when detecting the toilet flushing by the water flow detection means or the water level detection means, if the elapsed time since supplying the sterilizing water to the previous toilet is more than a predetermined time, the sterilizing water is generated and flowed to the toilet To.
[0011]
The life of the electrolyzed water generating device (for example, the electrode life when the sterilizing water is generated by electrolysis) is increased compared to the one that generates sterilizing water every time the toilet bowl is cleaned. Long life can be achieved.
[0012]
In addition, the number of times the toilet bowl is washed is counted based on a signal detected by the water flow detection means or the water level detection means, and the count value is less than a predetermined number and the elapsed time from the previous supply of sterilizing water to the toilet bowl is a predetermined time. In some cases, sterilizing water is generated and allowed to flow through the toilet bowl.
[0013]
The life of the electrolyzed water generating device (for example, the electrode life when the sterilizing water is generated by electrolysis) is increased compared to the one that generates sterilizing water every time the toilet bowl is cleaned. Long life can be achieved.
[0014]
Furthermore, the number of times the toilet bowl is washed is counted based on the signal detected by the water flow detection means or the water level detection means, and the counted value is less than a predetermined number and the elapsed time from the previous supply of the sterilizing water to the toilet bowl is a predetermined time. In some cases, the sterilizing effect is more reliable by generating sterilizing water and flowing it in the toilet bowl.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described with reference to the drawings.
As shown in FIG. 1, a toilet device to which the toilet bowl sterilization method of the present invention is applied includes a flush water storage section 1 for storing flush water supplied to a seat-type toilet, and opens and closes water supply to the flush water storage section. A ball tap 2 that is connected to a drain valve 3 that opens and closes the supply of flush water in the toilet bowl, and is connected to the drain valve 3 by a ball chain, and is rotated by a user operation or a motor. A float lever that lifts the drainage valve 3 and a float that, in conjunction with the ball tap 2, floats the ball tap until the water level reaches a predetermined water level after the water level in the wash water reservoir 1 drops during toilet cleaning. It consists of five.
[0016]
When the drain valve 3 is opened and toilet flushing is performed, the ball tap 2 is opened in conjunction with the lowering of the water level in the wash water reservoir 1, and water supply to the wash water reservoir 1 is started and the ball tap 2 comes out. The water falls directly into the washing water reservoir 1 and also falls into the washing water reservoir 1 from the hand washing water discharge pipe 6. The drain valve 3 closes within a few seconds after opening, but the ball tap 2 is opened until the float 5 rises to a predetermined water level.
[0017]
At this time, the water discharged from the ball tap 2 is also supplied to the sterilizing water generator 8 through the branch passage 7. The sterilizing water generator 8 is provided in the washing water reservoir 1 by a water discharge passage 9 after reforming the water supplied from the branch passage 7 so as to have sterilization properties by adding electrolysis or a sterilizing agent. The overflow pipe 10 is allowed to flow into the toilet. The overflow pipe 10 communicates with the toilet regardless of whether the drain valve 3 is open or closed.
[0018]
Next, the structure of the sterilizing water generator 8 will be described with reference to FIG. The water supplied from the branch passage 7 passes through the water flow sensor 11, is electrolyzed into hypochlorous acid-containing water having sterilizing power by the electrolytic bath 12, and then supplied to the toilet through the water discharge passage 9. Here, when the water flow sensor 11 detects the water flow, the control unit 13 is configured to conduct the electrolysis by energizing the electrolytic cell 12, and when the water flow sensor 11 stops detecting the water flow, the electrolysis by the electrolytic cell 12 is performed. Stopped.
[0019]
In FIG. 3, a float switch 14 is provided in the toilet flushing water storage unit 1 instead of the water flow sensor 11 to detect a water level change due to toilet flushing, and the control unit 13 automatically starts and stops electrolysis by the electrolytic cell 12. Is what you do.
[0020]
As described above, the toilet cleaning is detected by the water flow sensor 11 or the float switch 14, and the sterilizing water can be automatically supplied to the toilet based on the detection. Therefore, the user does not have to perform an operation for supplying the sterilizing water. Sterilized water can be supplied to the toilet bowl every time the toilet bowl is washed, and a reliable sterilizing effect can be obtained.
[0021]
In addition, in order to supply sterilizing water to the toilet bowl in synchronization with the water storage operation in the toilet flushing water storage section, sterilizing water is supplied to the stagnant water in the water seal section of the toilet trap section that has stopped flowing immediately after toilet flushing The sterilizing effect can be made effective until the next toilet flushing.
[0022]
In the above-described embodiment, an example in which toilet flushing is detected by the water flow sensor 11 and the float switch 14 and sterilizing water is supplied to the toilet every time toilet flushing has been described, but the sterilizing water generator 8 is extended in life. An embodiment in which the generation of sterilizing water is limited in order to reduce the energization time of the electrolytic cell 12 and suppress the consumption of the electrode will be described with reference to FIGS.
[0023]
FIG. 4 is a toilet sterilization flow activated every predetermined number of times. First, the state of the water flow sensor 11 or the float switch 14 is read. If the water flow sensor 11 or the float switch 14 is “ON”, it is determined that toilet flushing has been performed (S41Y), and the counter K for counting the number of toilet flushes is equal to or greater than a predetermined number. Is detected (S42). When it is determined that the number of times the toilet bowl has been washed is greater than or equal to the predetermined number (n times) since the sterilizing water was supplied to the toilet bowl (S42Y), the sterilizing water generator is supplied to the washing water storage tank 1 in S42 and S43. While water is also supplied to 8, sterilizing water is generated by the electrolytic cell 12. Thereafter, when there is no water supply to the sterilizing water generator 8 (S44N), the power supply to the electrolytic cell 12 is stopped to stop the generation of sterilizing water (S45) and the counter K is cleared (S46).
[0024]
If it is determined in S42 that the number of times the toilet bowl has been washed is not greater than or equal to the predetermined number (n times) since the sterilizing water was supplied to the toilet bowl (S42N), the washing water storage tank 1 is supplied with water in S47 to generate sterilizing water. While water is also supplied to the vessel 8, sterilizing water is generated by the electrolytic cell 12. Thereafter, when there is no water supply to the sterilizing water generator 8 (S47N), the counter K is incremented (S48). In this way, when the number of washings after supplying sterilizing water to the toilet bowl last time is more than a predetermined number of times, the generation of sterilizing water and flowing it to the toilet bowl, It is effective when the number of times of use is generally determined in the morning, noon, and night in the life. For example, the number of times of use in the morning is grasped in advance, and the time can be set so as to generate sterilized water at the end.
[0025]
FIG. 5 is a toilet sterilization flow activated every predetermined time. In this flow, instead of the processing of S42 in the flow of FIG. 4, it is determined whether or not the elapsed time since the supply of sterilizing water to the toilet bowl by the timer T1 last time is equal to or longer than the predetermined time t1 as in S52. I have to. Thus, by sterilizing the toilet according to the elapsed time since the sterilizing water was supplied to the previous toilet, it is effective for toilets in public facilities where the number of users and the number of times are difficult to specify.
[0026]
FIG. 6 is also a toilet sterilization flow activated every predetermined time. First, in S61, it is determined whether or not the timer T2 that measures the elapsed time since the sterilizing water was supplied to the toilet bowl last time is equal to or longer than the predetermined time t2, and if it is determined that the predetermined time has elapsed (S61Y). 1), the toilet lever is automatically washed by rotating the drain lever 4 shown in FIG. 1 by an electric motor (not shown). As a result, water supply to the washing water storage tank 1 is started and the sterilizing water generator 8 is also started. When water is supplied, sterilizing water is generated by the electrolytic bath 12 during the period when the sterilizing water generator 8 is supplied (S63, S64). Thereafter, when there is no water supply to the sterilizing water generator 8 (S64N), the power supply to the electrolytic cell 12 is stopped to stop the generation of sterilizing water (S65) and the timer T2 is restarted (S66). The timing of the sterilization time of the toilet bowl by T2 is started.
[0027]
Since the number of bacteria in the toilet water increases in proportion to the amount of time left, it is ensured by automatically supplying sterile water to the toilet whenever the bacteria grow and cause odors and dirt. The toilet bowl can be sterilized.
[0028]
FIG. 7 is a combination of the flow of FIG. 4 and FIG. 5. When it is determined in S72 that the number of toilet flushes is not more than the predetermined number (n times) since the sterilizing water was supplied to the previous toilet (S42N). ) The process proceeds to S76, and if the elapsed time since supplying the sterilizing water to the toilet bowl by the timer T1 is equal to or longer than the predetermined time t1 (S76Y), the electrolytic cell is used for the period when the sterilizing water generator 8 is supplied with water. 12 produces sterilized water (S73, S74).
[0029]
FIG. 8 is a combination of the flow of FIG. 4 and FIG. 6. Even if it is not detected that toilet flushing has been performed in S81 (S81N), the process proceeds to S87, and sterilizing water is supplied to the previous toilet. If the elapsed time from the start is equal to or greater than the predetermined time t2 (S87Y), the toilet bowl is automatically washed (S88), and the process proceeds to S83 to supply sterilized water to the toilet bowl.
[0030]
FIG. 9 is a combination of the flow in FIG. 5 and FIG. 6. Even if it is not detected that toilet flushing has been performed in S91 (S91N), the process proceeds to S97 and sterilizing water is supplied to the previous toilet. If the elapsed time since the start is equal to or greater than the predetermined time t2 (S97Y), the toilet is automatically washed (S98), and the process proceeds to S93 to supply sterilized water to the toilet.
[0031]
In the flow of FIG. 7 to FIG. 9, the number of times the toilet bowl was washed and the elapsed time since the sterilizing water was supplied to the toilet bowl last time are used together, or the toilet bowl is automatically washed, so Proliferation can be reliably suppressed.
