Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a simple water purifier, particularly a simple water purifier that allows tap water to be easily purified at home.

[Conventional technology]

With the rise of high-rise housing complexes, the water supplied to each home is pumped up into water tanks installed on the roof, and water is then supplied to each home.

Water purifiers are increasingly being used at home to remove impurities from the tap water stored in the water supply tank and to obtain delicious drinking water at home.

Conventionally, commercially available water purifiers of this type have been equipped with filters such as activated carbon or hollow filters, as shown in Figure 4.
A filter type was common in which tap water was purified using No. 1,22.

[The problem that the idea aims to solve]

Conventional filter water purifiers have the disadvantage that their purification performance deteriorates over time because impurities contained in tap water are collected in the filters 21 and 22. Since the impurities collected by the filters 21 and 22 also include organic substances, various germs are likely to propagate, and it is necessary to take measures to prevent this propagation.Furthermore, it is necessary to frequently replace the filters 21 and 22. , 22 is troublesome to replace, and the running cost is high.

To solve the above-mentioned problems, the present invention aims to provide a simple water purifier that does not deteriorate in purification performance with use, does not require the trouble of replacing device parts, and can easily obtain delicious purified water at home without the proliferation of bacteria.

[Means to solve the problem]

In order to achieve the above object, the simple water purifier according to the present invention includes a cylindrical tank, a plurality of electrodes disposed in the tank, and a direct current flowing through the electrodes in order to apply an electric field to the water to be purified in the tank. In a simple water purifier equipped with a DC power supply that supplies voltage, the cylindrical tank is arranged so that its longitudinal direction is perpendicular to the ground, and the cylindrical tank is provided near the lower end to be purified. a water inlet for guiding water into the cylindrical tank; a water intake for guiding purified neutral water received at the upper end of the cylindrical tank to a water purification pipe; and a direct current applied to the electrode section. a first drain port for discharging acidic water separated by voltage; and a second drain port for discharging alkaline water separated by DC voltage applied to the electrode section; Acidic water from the drain port No. 1 and the above No. 2
It is characterized by being equipped with a switching valve that selectively takes out alkaline water and alkaline water from the drain outlet. This will be explained below with reference to the drawings.

〔Example〕

Fig. 1 is a diagram explaining the principle of the simple water purifier according to the present invention, Fig. 2 is a configuration diagram of one embodiment of the simple water purifier according to the present invention, and Fig. 3 is another embodiment of the simple water purifier according to the present invention. This figure shows an explanatory diagram of the layout of the water inlet, water intake, and drainage outlet.

In FIG. 1, numerals 1 and 2 represent electrodes, and 3 represents a DC power source. The positive side of a DC power source 3 is connected to the electrode 1, and the negative side of the DC power source 3 is connected to the electrode 2, and an electric field is applied between these electrodes 1 and 2.

On the other hand, when tap water introduced from a storage tank on the rooftop passes between electrodes 1 and 2, which are installed opposite each other, impurities contained in the tap water are ionized positively or negatively. Since there are many tendencies, positively ionized impurities are guided toward the electrode 2 side, and negatively ionized impurities are guided toward the electrode 1 side. Therefore, near these electrodes 1 and 2, the concentration of impurities contained in tap water increases,
These electrodes 1, continuously or at appropriate timing.
By draining impurities floating near the electrodes 2 as drain water, the tap water that has passed between the electrodes 1 and 2 is purified.

FIG. 2 shows an embodiment of the simple water purifier according to the present invention.

A water inlet 5 is provided at the lower end of the tank 4, and a water intake 6 and drain ports 7, 8 are provided at the upper end of the tank 4. Two electrodes 1 and 2 are arranged opposite to each other on the outer wall of the tank 4, and the voltage supplied from the DC power supply 3 allows
An electric field is applied within the tank 4.

A three-way valve device 9 is attached to the inlet 5 provided at the lower end of the tank 4, and water is introduced from the water pipe 11 by rotating the three-way valve device 9 electrically or manually by rotating the knob 10. It is also possible to conduct the tap water to the water inlet 5, and to drain the water accumulated in the tank 4 from the drain pipe 12 via the water inlet 5 if necessary.

A water intake port 6 and drain ports 7, 8 provided at the upper end of the tank 4 are each led to a switching valve 13. A three-way valve is provided in each of the switching valves 13, and a water purification pipe 14 and a drain pipe 1 are connected from the switching valve 13.
5 is attached. During normal purification, purified water taken from the water intake 6 is guided to the purified water pipe 14, and waste water taken from the drains 7 and 8 is discharged from the drain pipe 15.

In such a simple water purifier with a vertical tank structure, the three-way valve device 9 is opened and the water pipe 11 is connected to the water inlet 5.
Tap water is introduced into the tank 4 through the tank 4. When power is applied from DC power supply 3 to electrodes 1 and 2, tank 4
An electric field is applied between the opposing electrodes 1 and 2 provided on the wall, and the tap water moves from the bottom to the top in this electric field. Many of the impurities in tap water are ionized, so as shown in Figure 2 (negatively ionized impurities move to the electrode 1 side, and positively ionized impurities move to the electrode 2 side). Since the tap water to be purified steadily flows in from the water inlet 5, the purified water that has passed approximately the center of the electrodes 1 and 2 passes through the water intake 6, and then passes through the switching valve 1.
The water is introduced to the water purification pipe 14 through the water pipe 3. The water purification pipe 14
The water obtained is purified water from which impurities have been removed, as explained in FIG.

Further, water in the vicinity of electrodes 1 and 2 is similarly moved upward and guided from drain ports 8 and 7 to drain pipe 15 via switching valve 13. Some of the water drained from these drain ports 8 and 7 is
As explained in the figure, the concentration of impurities induced into the electrodes 1 and 2 and ionized into negative and positive ions is high, and is discharged from the drain pipe 15 continuously or intermittently.

When the purified water obtained in this way or already purified tap water is introduced into the tank 4 from the inlet 5 and a voltage is applied to the electrodes 1 and 2, neutral water is collected from the water intake 6, Negative ions in the water in the tank 4 are attracted to the electrode 1 side, and positive ions are attracted to the electrode 2 side, so that alkaline water is collected from the drain port 7 and acidic water is collected from the drain port 8. .

By appropriately switching the three-way valve in the switching valve 13, (a) neutral water from the water purification pipe 14, alkaline water + acidic water from the drain pipe 15 (b) neutral water + alkaline water from the water purification pipe 14, and water from the drain pipe 15. Acidic water (c) Neutral water + acidic water from water purification pipe 14, drain pipe 1
Each purified alkaline water can be obtained from 5.
