Definitions
- This invention relates to a water purifier.
- water purifiers that purify raw water such as tap water and well water and supply purified water.
- a general water purifier such as a household faucet direct-coupled water purifier
- water is retained in a filter medium (water purifying cartridge) or a water passage in the water purifier after supplying the purified water. If the water is left in the water purifier and left for a long time, bacteria will grow in the water purifier, which is unsanitary.
- bacteria are likely to grow in the retained water in the water passage on the secondary side after passing through the filter medium, that is, on the downstream side of the filter medium. This is because the chlorine component in the raw water is removed by the activated carbon in the filter medium.
- the water purifier manufacturer resumes using the water purifier supplied from the water purifier first every day or when the water purifier has not been used for several days.
- the user is prompted to perform so-called discarded water, such as purified water supplied from a water purifier, after the first use of the water purifier after the resumption of use.
- Patent Document 1 when a period of time during which water is not passed continues for a predetermined time or longer, the length of the water staying in the water purifier is long enough to be discarded.
- a water purifier is described that generates alarms for time, waste water and cleaning.
- the washing time may be changed according to the length of time during which water is not passed.
- the waste water time may be corrected based on the detection signal of the flow sensor during the waste water execution.
- Patent Document 2 when the water purifier is not used for a certain period of time, the orange LED is lit until the discharge of the remaining water in the water purifier is completed, and thereafter By turning on the green LED, the user is informed of the availability of clean water.
- the stop state of the stop valve is detected and the period is calculated. Displayed as the number of days remaining. When the staying days exceed the specified staying time, when the user throws away the staying water from the water pipe, the contents of the subtraction counter used as a guide for the amount of the staying water are displayed and the indicator lamp blinks. .
- Patent Document 5 when a time interval from when a faucet for flowing tap water into the activated carbon tank is opened to when it is opened is over a certain time, the activated carbon tank Sterilize and wash with tap water flowing from the secondary side to the water tap for a set time.
- Patent Document 6 when the residence time of the purified tap water exceeds a predetermined set time, the electromagnetic valve for waste water is opened and stays there. Waste water treatment is performed. When a predetermined opening time elapses, the electromagnetic valve for waste water is stopped.
- the amount of waste water is not only the amount necessary for discarding the accumulated water, but also the amount necessary for cleaning the inside of the water passage and the filter medium.
- Patent Document 1 In the water purifier described in Japanese Patent Application Laid-Open No. 9-141250 (Patent Document 1), once the discarded water is started, the accumulation of the time when water is not passed stops. In addition, in this water purifier, since the waste water is mainly used to throw away the accumulated water, even if the waste water is stopped halfway before the required amount of waste water is started after the start of the waste water, The setting of the amount of discarded water is not changed. Even in the water purifier described in JP-A-11-169844 (Patent Document 2), if the faucet is closed while discarding water, the setting of the amount of discarded water is not changed.
