Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a water treatment apparatus such as a water conditioner or a water purifier.
[0002]
[Prior art]
In the water conditioner and the water purifier, activated carbon or the like is used as a filter medium to treat residual chlorine, organic matter, and the like in tap water. Since the residual chlorine, which is a disinfectant, has been removed from the water after passing through the filter medium by this activated carbon or the like, the residual water remaining in the filter medium or in the container when the water conditioner and water purifier are not used for a long time. There is a problem that bacteria in the water grow. In general, in order to suppress the growth of bacteria, a method using antibacterial activated carbon with silver attached as activated carbon in the filter medium is used. When this antibacterial activated carbon comes into contact with water, it elutes silver ions, and the silver ions can suppress bacterial growth.
[0003]
[Problems to be solved by the invention]
However, antibacterial activated carbon impregnated with silver has a silver ion elution period of about several days, and there is a problem that it is not possible to suppress bacterial growth in the residual water inside the filter medium and the residual water remaining in the main body for a long time. is there.
The object of the present invention is to solve the problems of the prior art.
[0004]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a water treatment apparatus equipped with a filter medium, provided on the upstream side of the filter medium, means for supplying silver ions by electrolysis of silver, timer means for detecting the passage of time, and And means for supplying silver ions by energizing the means for supplying silver ions by electrolysis of silver based on the elapsed time from the timer means . The silver ions can suppress the growth of bacteria in the residual water in the water treatment apparatus and the retained water of the filter medium. In addition, since the supply is performed based on the elapsed time by the timer means, there is an effect that silver ions can be reliably supplied.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
In FIG. 1, supply water such as tap water is supplied to the water purification cartridge 10 from the upstream side, and the supply water is purified by a filter medium such as activated carbon stored in the water purification cartridge 10 to flow downstream.
A silver ion intermittent supply device 2 is provided on the upstream side of the water purification cartridge 10, and silver ions are intermittently added to the supply water. The silver ions added to the supply water are adsorbed by the filter medium (activated carbon etc.) of the water purification cartridge 10 and maintain the antibacterial action for a predetermined time even after the supply of silver ions from the silver ion intermittent supply device 2 is stopped. ing.
[000 6 ]
Silver ion intermittent supply device 2, in this embodiment has a feed device by electrolysis of silver, silver electrode and insoluble electrode silver dissolving tank is in mounted configuration as shown in FIG. Silver ions are intermittently supplied into the supply water by energizing the electrodes every predetermined time.
[000 7 ]
The flow path of the feed water flow rate counter 5 is provided. In this embodiment, a flow rate counter 5 is provided between the silver ion intermittent supply device 2 and the water purification cartridge 10 to send a flow rate signal to the supply control device 3.
The supply control device 3 obtains a cumulative flow rate value based on the flow rate signal from the flow rate counter 5, and when the predetermined value is reached, the silver ion intermittent supply device 2 is energized for a predetermined time and supplied with silver ions for a predetermined time. Has been.
[000 8 ]
The supply control device 3 is also provided with a timer 6 for measuring time. It is configured to perform the energization control of the silver ions intermittent supply device 2 by the counting of this time.
The determination by the flow rate counter 5 and the determination by the timer 6 may be used together.
[000 9 ]
The operation will be described with reference to FIG.
The supply control device 3 inputs a signal from the timer 6 (step S30), and when a predetermined time has passed (step S31), the silver ion intermittent supply device 2 is energized for a predetermined time (step S32). When the energization time has elapsed, the process returns to step S30.
By the above operation, silver ions are accurately supplied from the silver ion intermittent supply device 2 every predetermined time.
[00 10 ]
According to the embodiment described above, in the water purifier or the water conditioner by supplying silver ions, the growth of residual water in the filter medium of the main body and bacteria in the staying water can be suppressed. Since intermittent driving of or silver ions intermittent supply device 2 can be performed accurately, it is possible to properly maintain the antimicrobial action.
[00 11 ]
【The invention's effect】
As described above, according to the water treatment apparatus of the present invention, there is an effect of suppressing the growth of bacteria.
