As shown in the figure, it can be manufactured by combining angles and the like. In addition, the box-like shape allows the storage of tools and equipment.

Regarding the connection of the electrolysis sterilizing water supply device to the water pipe of the toilet unit, as shown in FIGS. 7 and 8, the end cap C at the left end of the water pipe 30 of the toilet unit is removed, and the water pipe is connected with the socket 42. 40 was connected and extended, and was connected to the water stopcock 15 in the front stage of the electrolyzed water generator through an elbow 44. The supply pipe 25 of electrolyzed sterilized water from the electrolyzed water supply device was connected to the flush water supply pipe 35A downstream of the flush valve 39 of the toilet unit via the check valve 26. The wash water control after using the toilet bowl was performed by the sensor D of the toilet bowl unit. The supply of the electrolyzed sterilizing water can be supplied at a predetermined time by a timer by the controller 7 in the function addition unit. In addition, by feeding back information on the normal toilet flush water supply from the sensor D to the controller 7 of the function addition unit,
Cleaning after using the toilet bowl and supply of electrolyzed sterilizing water were not performed at the same time, but cleaning was performed first. This prevented the sterilized water immediately after being supplied from being diluted by the toilet bowl cleaning. When the toilet unit does not have a sensor for cleaning water, the controller 7 of the function addition unit can control the toilet cleaning and the sterilizing water supply.

In the first embodiment, after connecting the piping of the function addition unit and the toilet unit, the function addition unit is mounted on the existing toilet unit and the front plate 2C, 2A, which is one plate up and down adjusted to the height after installation, The front surface was covered with 2B, 2A, and 2C, and the front plate had a seamless shape. First, the front plates 2A, 2

Further, in the second embodiment, the front plate 12 that covers only the function-added unit after connecting the piping of the function-added unit and the toilet unit is used, and the front plate of the existing toilet unit is used as it is. The installation was completed as in the first example. By matching the materials and colors of the front plate 12 and the front plates 22C, 22A, 22B, 22A, and 22C of the existing toilet unit, it is possible to make the appearance look natural. In this embodiment, the counter of the existing toilet unit is used as it is as the counter after the function addition unit is installed, but it is also possible to use a new counter.

For example, as a new counter, it is preferable to use a counter having a non-slip treatment such as embossing on the exposed upper surface. By this anti-slip process, the luggage placed on the counter can be prevented from slipping and the counter can be used more effectively. As the slip stopper, there is knurling or the like such as sticking of rubber or the like. Also, as shown in FIG. 14, if a sterilizing function is added by coating a photocatalyst made of titanium oxide or an antibacterial material 4A such as silver or copper with resin on the upper surface of the counter, it is hygienic and user-friendly. Can be used for storing luggage, etc. with peace of mind.

(Operation of Function Adding Unit) The operation after the function adding unit of this embodiment is attached to the existing toilet unit 31 is as follows. First, when the first toilet bowl T is used, the sensor D of the toilet bowl T detects this and sends a detection signal to the flash valve 39. Upon receiving the detection signal, the flush valve 39 opens the flush valve 39 of the toilet T for a predetermined time. As a result, the water in the water supply pipe 30 is supplied to the cleaning water supply pipe 35 and the flush valve 3
Water is discharged into the toilet via the discharge port S provided on the upper portion of the toilet T via 9. The wash water used to wash the toilet T is discharged from the trap portion of the toilet T to the drain pipe 24.

In addition to this normal cleaning, a timer is built in the controller 7 in the function addition unit,
When the predetermined operation time arrives, the following processing is performed. First, the electromagnetic valve 19 is opened to guide the water in the water supply pipe 40 to the electrolysis tank 5 via the water supply pipe 45 for the electrolysis tank. At this time, since the amount of water flowing into the electrolysis tank 5 per unit time becomes constant by the constant flow valve 18, the concentration of free chlorine and the like generated by electrolysis also becomes constant. The controller 7 applies a voltage between the adjacent electrodes of the electrolysis tank 5 at the same time as opening the solenoid valve 19 or with a slight delay. Since tap water such as tap water and tap water contains chlorine ions, the water flowing between the electrodes is electrolyzed by this current to generate free chlorine and bound chlorine. In addition, regarding the electrolysis of this chlorine ion, PCT / JP95 / 01
036 has detailed disclosure. The electrolyzed water generated in the electrolysis tank 5 has a sterilizing property, and the electrolysis sterilized water is stored in the storage tank 6. The storage amount is detected by a float switch (not shown) in the storage tank, a detection signal is sent to the controller 7, and the controller 7 closes the electromagnetic valve 19 and stops electrolysis. After that, the controller 7 activates the pump P at an appropriate timing and opens the electromagnetic valve 29 for a predetermined time to supply the electrolyzed sterilized water stored in the storage tank 6 to the first toilet bowl T. The storage tank 6 is provided by a float switch lower than the float switch.
A decrease in the amount of water inside is detected, a detection signal is sent to the controller 7, and the controller 7 stops the operation of the pump P and closes the electromagnetic valve 29. In the case of the present embodiment, the same outlet S as that for the wash water was used to supply the sterilizing water to the toilet, but the outlet may be provided separately in the toilet. Further, it is also possible to fetch information from the use detection sensor D into the controller 7 and cause the electrolysis sterilizing water to flow depending on the number of times the toilet is used.

As described above, by supplying the electrolyzed sterilized water stored in the storage tank 6 to the toilet T at once with the pump P, the electrolyzed sterilized water can be diffused over a wide range in the toilet. , It is possible to sterilize the entire toilet bowl. A spreader may be provided at the outlet S of the electrolyzed sterilized water in order to diffuse the electrolyzed sterilized water more widely in the toilet bowl. The time for opening the solenoid valve 29 is appropriately set according to the amount of electrolyzed sterilizing water flowing in the toilet, but it is desirable that this amount be such that the accumulated water in the toilet trap can be replaced. With a normal urinal, it is appropriate that the volume is about 2 liters or more. The capacity of the storage tank 6 may be set to be substantially equal to the amount used once, or may be equal to the amount used twice. When the capacity of the storage tank 6 is only one-time use, the controller 7 opens and closes the electromagnetic valve 29 of the first toilet, waits until the electrolysis sterilizing water fills the storage tank 6 again, and then The solenoid valve 29 of the second toilet is opened. Moreover, you may perform simultaneously. The water stopcock 15 and the check valve 16 are provided for the following purposes. First, when maintenance of the electrolysis tank 5 is required, such as when the electrodes of the electrolysis tank 5 are replaced, the water stopcock 15 is closed to shut off clean water or middle water. The same applies to other maintenance such as the storage tank 6. Further, the check valve 16 prevents the free chlorine-containing water generated in the electrolysis tank 5 from flowing back into the water supply or the tap water of the water supply pipe. Further, without using the storage tank 6 and the pump P, the electrolyzed sterilizing water generated in the electrolysis tank 5 may be continuously supplied to the toilet bowls T, T.

Further, the electrolysis tank 5 may be provided in series with the flash valve 39, upstream or downstream thereof. When provided on the downstream side, the electrolysis tank 5 may be provided for each toilet bowl. In each of the above examples, a two-way toilet unit is taken as an example for convenience of description, but it is applicable to a multi-unit toilet unit including three or more toilets, as well as a toilet unit including one toilet.

(Mechanism of Antifouling such as Removal of Urine Stones with Sterilized Water) Free chlorine produced by electrolysis exists as hypochlorous acid (HClO) in an acidic state, and in this form, it is an alkaline existing form. Hypochlorite ion (ClO
^The bactericidal power is about 10 times stronger than that of-). In addition, even if it is neutral, a powerful sterilizing power intermediate to that can be obtained. In addition, bound chlorine produced by electrolysis of intermediate water also has sterilizing power. Therefore, the water electrolyzed in the electrolysis tank 5 is sterilizing water having a strong sterilizing power. The sterilizing water thus generated in the electrolysis tank 5 is passed through the sterilizing water supply pipe 25 to the toilet T
Supplied to sterilize bacteria in the toilet bowl. ,

The mechanism of attachment of urinary stones to the toilet bowl is considered to be as follows. When urine is discharged to the toilet bowl, the urine adheres to the surface of the toilet bowl and accumulates in the accumulated water in the toilet bowl. Generally, bacteria such as bacilli are present in the toilet bowl. Urine contains a large amount of urea, but when bacteria are present in the surface of the toilet bowl or in the accumulated water on the toilet bowl, urea is decomposed into ammonia and carbon dioxide by the action of urease enzyme urease. If the amount of ammonia produced at this time is large, it contributes to a strange odor. Further, when ammonia is generated, it is dissolved in the liquid adhering to the surface of the toilet bowl or the accumulated water in the toilet bowl trap, etc., and the pH of the liquid rises. When the pH rises, the liquid that adheres to the surface of the toilet bowl and the calcium ions contained in the accumulated water in the toilet bowl will change into form carbonates and phosphates, which will deposit as urine stones and cause stains on the toilet bowl. Becomes In the electrolysis sterilizing water supply device of the function addition unit according to the present invention, by sterilizing the sterilizing water generated in the electrolysis tank to the toilet bowl, in order to sterilize the bacteria such as the bacillus present in the toilet bowl, The cause of adherence of urinary stones is eliminated, the toilet bowl is always kept clean, and the generation of odor due to Ammonia is prevented.
