摘要： PROBLEM TO BE SOLVED: To enable a user to easily detect the time for exchange of electrodes by the consumption of the electrodes by providing the above device with electrode state detecting means for detecting the abnormality of the electrodes in accordance with the energizing state to the electrodes. SOLUTION: This toilet bowl sterilization device has at least a pair of the electrodes 5 which are disposed to face each other in parallel apart a prescribed spacing and consists of metals (silver, etc.), at least either of which elutes sterilizable metal ions (silver ions, etc.). The abnormality is detected by passing constant current to the electrodes 5 and monitoring the voltage between the electrodes 5. Namely, the voltage is monitored and is kept stored in a control means 1 at every number of use times, for example, every 100 times, of the toilet bowl sterilization device. When the electrodes consume and the areas of the electrodes 5 decrease successively, the gentle voltage increase is observed according to the number of use times. When the electrodes 5 are completely consumed, the voltage increase does not appear any more. The consumption of the electrodes 5 is decided from this phenomenon and the exchange of the electrodes 5 is carried out. When the abnormality is detected, the abnormality is announced by a buzzer 13.

摘要： PROBLEM TO BE SOLVED: To prevent adhesion of scale and slime and generation of bad odor and facilitate the mounting work of the device by connecting an electrolytic part for eluting sterilizable metal ions and a controller for controlling a current- carrying condition through electric cables, in a water reservoir tank of a flush toilet system. SOLUTION: An electrolytic part 3 and a controller 1 are provided in a low tank 10 connected to a toilet stool 14 and electrodes 5, 6 eluting sterilizable metal ion of the electrolytic part 3 are connected to a water level sensor 7 through an electric cable 8. In this way, opened condition of a cleaning valve 13 is detected by a water level sensor 7 because of fall of water level and since electric currents are supplied to the electrodes 5, 6 by restoration of water level, sterilizable metal ions are eluted and cleaning water for the toilet stool containing sterilizable metal ions is stored in the low tank 10. Hence, adhesion of scale and slime and generation of bad odor are prevented. And further, the attaching work is easy and it can be used for a long time despite a small and light weight device.

摘要： PROBLEM TO BE SOLVED: To keep the concentration of silver ion in bathtub water at a prescribed concentration or more, to filter the pollutant by the short-time circulation of the bathtub water, and to prevent the clogging of a filter device by stopping the operation of a circulation pump after forming silver ions in the bathtub water to purify the bathtub water. SOLUTION: After a prescribed concentration of silver ion is generated in bathtub water, a circulating pump is turned ON/OFF. Actually, the pump is turned OFF for time T, and the pump is then turned ON for time tb. During the time T of OFF of the circulating pump, propagation of bacteria in the bathtub water can be suppressed by the sterilizing effect of silver ions to prevent the rise of turbidity and generation of slime and odor by the bacteria. After the OFF operation of the circulating pump for the time T, the circulating pump is turned ON for the time tb to perform the filtration of pollutant coagulation. Namely, since the pollutant is condensed in the bathtub bottom part by the condensation effect of silver ions, the pollutant coagulation has a large effective volume and is easily filtered to shorten the filtration time.

摘要： PROBLEM TO BE SOLVED: To prevent occurrence of black stains in a flushing toilet stool by providing a process supplying a flushing water containing silver ion to the flush toilet stool and a process supplying a flushing water not containing silver ion thereto. SOLUTION: After a user has used a urinal 1, a water supply valve 24 is opened by the actuation of an automatic toilet flushing system 3 and city water flows to an electrolytic tank 25 through a water supply pipe 23 and a flow sensor 32, and is supplied to the urinal 1 and water not containing silver iron is filled in the voids of scale as a porous body of a bowl face of the urinal and subsequently, after a specified time interval, electric energy of the electric source 33 is supplied to electrodes in an electrolytic cell 25 through a controller 27 to elute silver ion by a flow sensor 32 which has detected start of washing of the toilet bowl. Accordingly, even in a flush toilet to which scale has stuck, black silver deposition is not brought about.

摘要： PROBLEM TO BE SOLVED: To provide a sterilizing device for toilet stool flushing water which has a function of preventing the sticking of fur and slime to a flush toilet stool and occurrence of odor and which is also easy to fit and does not require labor for replacement. SOLUTION: A water storing part of a flush tank is provided with at least one pair of electrodes 6a and 6b at least one of which is a silver one. By impressing the silver electrode used as an anode, therefore, a current flows between the electrodes and silver ions dissolve from the silver electrode being the anode and are supplied into toilet stool flushing water. Since the toilet stool flushing water being present in the flush tank 22 and containing the silver ions is supplied to a flush toilet stool 1 after the flush toilet stool 1 is used, the toilet stool flushing water containing the silver ions stay in a trap part of the flush toilet stool 1 after filth is flushed away. According to this constitution, the inside of the flush toilet stool is sterilized by the silver ions and sticking of fur and slime due to propagation of miscellaneous bacteria and the consequent of occurrence of odor can be prevented.

摘要： PROBLEM TO BE SOLVED: To make it possible to wash the anus, the neighborhood of a bidet, etc., with suitable water while maintaining portability with a portable washing device which is portable and has a spouting mechanism for spouting the fed water to the local part of the human body by removing metal ions from the fed water. SOLUTION: The city water is put into the portable washing device 10 from a water inlet 12 and is led to a tank 14 in the state of holding this tank 14 in such a manner that a nozzle 20 faces downward and the water inlet 12 faces upward. The city water in the tank 14 is passed through the inside of a cartridge 16 by a pump and is spouted from a discharge port 24a via the nozzle 20 when a discharge button 18 is pushed. At this time, the spouted water comes into contact with the ion exchange resin 16a in the cartridge 16, by which hydrogen ions and the cations, such as calcium ions, present in the water are exchanged. Then, a user is able to wash the local part by the weakly acidic water which is soft water formed by removing the calcium ions, etc., from the city water and is added with the hydrogen ions.

摘要： PROBLEM TO BE SOLVED: To provide a method for generating a weak acidic softened water, which is capable of controlling the life of a cation exchange resin and to be acidic in a required pH. SOLUTION: City water to be treated flows at first into a vessel 1 packed with the cation exchange resin and the weak acidic softened water is obtained by ion-exchanging the hydrogen ion existing in the cation exchange resin with a hardness component such as calcium ion, magnesium ion present in the city water. Next, the weak acidic softened city water is passed through an electric generator with an impeller, which is at a poststage of the vessel 1 packed with the cation exchange resin, to rotate the impeller to generate electric power in the electric generator 2. Next, the city water is passed through a pH sensor part 4 provided at the poststage of the electric generator 2. At this time, the output of the pH sensor part 4 is displayed on a pH indicator 3 as shown by a broken line and the detected pH is outputted by the pH indicator 3. The city water passed through the pH sensor part 4 is weak acidic and softened.
