DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for activating water by magnetism, which is used by being installed in a water supply pipe of a water supply in a home or the like.

[0002]

2. Description of the Related Art It is said that when water is passed through a magnetic field, the water is activated and becomes delicious water. This is because water molecules passed through a magnetic field become smaller when there are 10 or more clusters of water molecules, and physical and chemical properties are changed by having high levels of energy, and It is attributed to such effects as a reduction in the amount of residual chlorine. Further, water whose clusters have been reduced by the magnetization treatment causes a change in osmotic pressure, which has the effect of preventing the growth of bacteria and algae in the water, and also has the effect of preventing red rust in piping. As a device for home use, as a device for improving the taste of drinking water, a magnetizing device for water used in combination with a water tap as in a water purifier using activated carbon or a reverse osmosis membrane is commercially available.

[0003]

In the water magnetizing apparatus used in connection with the above-mentioned water tap, water passes through a magnetic field only once. However, as will be described later, according to the findings of the present inventors, it has been found that passing through the magnetic field a plurality of times is more effective than passing through the magnetic field only once, and that the flow rate of water and the strength of the magnetic field also affect the effect. are doing. In view of the above, the present invention aims to provide a water magnetizing apparatus which is superior in performance to the conventional water magnetizing apparatus, is easy to install, and has excellent versatility.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an intake pipe for supplying water to a closed tank except for having an air port at an upper portion is connected to the intake pipe. A water stop valve that closes when the liquid level of the tank reaches a full level is provided, and the tank is provided with a water supply pump that operates by detecting a decrease in water pressure on the pump outlet side and that sends out water from the tank. Is connected in series with a circulating pump and a magnetizing device having a permanent magnet for giving a magnetic field to water, and both ends thereof are connected . Furthermore, the circulating pump is operated in conjunction with the start of operation of the water supply pump. is, the control device is provided for operating for a predetermined time t ₃ when the stopped after the operation for a predetermined time t ₁ after the end of operation of the water supply pump and the circulation pump is continued while the stopped state for a predetermined time t ₂ characterized in that Which is the magnetization process equipment.

[0005]

FIG. 1 shows an example of the apparatus of the present invention.
In the drawing, reference numeral 1 denotes a tank for storing water 2. 3
Is connected to a water pipe by a water intake pipe, and a water stop valve 4 is provided at an end of the tank to detect a water level by a float 5 and to close when a water level of the tank reaches a predetermined position. An electromagnetic valve may be used as the water stop valve, and a separate water level sensor may be provided to open and close by a signal from the water level sensor. Reference numeral 6 denotes a water supply pump, which detects when water is used and the water pressure in the water distribution pipe 7 is reduced by a pressure switch (not shown), whereby a motor (not shown) incorporated in the water supply pump rotates to send water to the water distribution pipe. It has become. Reference numeral 8 denotes a circulation pump, 9 denotes a magnetizing device, which takes in water in the tank from a suction pipe 10 and discharges water from a tank 11
To spit out. The positions of the circulation pump and the magnetizing device may be reversed from those in FIG. 1 as long as they are arranged in series. In addition, reference numeral 12 is a tap so that water in the tank can be directly taken out and used. Reference numeral 13 denotes an overflow port when the water level rises abnormally, and also serves as an air port. Of course, an air port may be separately provided.

In the above apparatus, the water in the tank passes through the magnetizing apparatus many times by the operation of the circulation pump.
At present, the principles and effects of water treatment by magnetism are not always completely elucidated, but according to the findings of the present inventors, the effect of magnetization treatment is better when passing through a magnetic field more than once. It was found that the analysis values of harmful substances such as trihalomethane decreased sharply. This is thought to be due not only to the effect of the magnetic field being repeatedly provided by circulating at a large flow rate as described below, but also to the effect of the stirring action. In this case, as shown in FIG. 1, when the discharge pipe 11 from the magnetizing device is above the water surface, air is entrained and the amount of dissolved oxygen increases,
Further, the emission of volatile harmful substances is promoted, which is particularly preferable.

Further, the flow rate of water passing through a magnetic field has not been noticed so far, and in fact, it is described that the effect of the magnetization treatment can be obtained even if a permanent magnet is immersed in water placed in a container. However, according to experiments performed by the present inventors, it has been found that a larger flow velocity has a larger effect. In the present invention, the flow rate of the circulation pump is 2.5 m / s or more,
Preferably, it is 3.5 m / s or more. The flow velocity of the conventional magnetizing apparatus is usually up to about 1 m / s, and this flow velocity is extremely high. However, the velocity of the water passing through the magnetic field increases, and the effect of the magnetic field can be exerted with high energy.

[0008] Table 1 shows the analysis values of the water components before and after the treatment when the effect of the magnetization treatment was examined using an experimental apparatus, and shows the influence of the flow rate of the circulating pump. Raw water before treatment is tap water, 5 liters of water in a water tank, and the magnetizing device used in the present invention circulated at a flow rate of 4 m / s for 30 minutes. / S circulated for 1 hour and left standing for 1 hour after completion of the process. The strength of the magnetic field for the magnetization process is 11 kG. Although the effects of the magnetizing treatment cannot be said to be all displayed by the measurement items shown in Table 1, even if the data shown in this table show that the flow rate is large, the effect of the treatment is remarkable. The reduction of certain trihalomethanes is significant. The term “NMR” in the table indicates the frequency of the half width of the nuclear magnetic resonance spectrum, and indicates that the smaller this value is, the smaller the cluster of water molecules is.

FIG. 2 is a sectional view showing an example of a magnetizing device used in the present invention.
The magnetic path may be formed by arranging 0 in the same direction across the nonmagnetic water pipe 21 and providing the yoke 22. When there is a magnetic field of sufficient strength, the effect of the magnetization treatment can be obtained in combination with the effect of the flow velocity. For this purpose, the strength of the magnetic field is preferably 7 kG or more. Therefore, rare earth magnets such as neodymium-iron magnets are suitable because they can generate a strong magnetic field.

The circulating pump may be operated continuously in a normal case, but is operated intermittently when the amount of water used is small and the capacity of the tank is relatively small compared to the amount of circulating water. To save energy. In addition, depending on the purpose of use, a minimum amount of residual chlorine may be required at the terminal faucet in order to maintain the sterilizing power of the water itself. In this case, however, it is necessary to limit the decrease in the amount of chlorine by intermittent operation.

FIG. 3 is a diagram for explaining the method of intermittent operation of the circulation pump. The timing of operation of the water supply pump and the circulation pump is shown with time on the horizontal axis. Although the water supply pump As seen in this figure is so also activated at the same time the circulation pump when starting, the circulation pump be stopped water supply pump is operated more constant by the time t _1.
This is to sufficiently magnetize the water in the tank in response to a part of the water in the tank being replaced with a new one. In the example of FIG. 3, the water supply is performed twice intermittently. However, the interruption time of the first and second water supply is shorter than t ₁ , so that the circulating pump is continuously operated without stopping during this time. In addition, as shown in FIG. 3, even when water is not used for a long time t _{2, the} circulation pump is operated for a certain time t ₃ to maintain the effect of the magnetization treatment. t ₁ and t
₃ time, eg 30 minutes, t ₂ may be a time such 5 hours.

FIG. 4 is a diagram showing an example of a control circuit for the intermittent operation of the circulation pump. Reference numeral 30 denotes a power supply, 32 denotes a motor of a water supply pump, and 44 denotes a motor of a circulation pump. When both motors are in a stopped state, the pressure switch 31 is closed and the motor 32 of the water supply pump (hereinafter simply referred to as a water supply pump) operates, and at the same time, the relay 33 is operated.
Is energized to close the contact 34 and the normally closed contact 38 of the timer 37 is closed, so the relay 39 is energized. As a result, the contact 43 is closed, and the motor 44 of the circulation pump (hereinafter simply referred to as the circulation pump) is activated in conjunction with the activation of the water supply pump.

When the pressure switch 31 is opened and the water supply pump 32
Stops and the contact 34 opens in conjunction with this, the contact 35
As a result, since the relay 39 is self-held, the relay 39 is kept energized, and the operation of the circulation pump is continued. On the other hand, when the water supply pump is stopped, the normally closed contact 36 of the relay 33 is closed and the timer 37 starts counting time. When the time t ₁ has elapsed and the normally closed contact 38 of the timer 37 opens, the relay 39 is deenergized and the circulation pump 44 stops.

Further, the circulation pump is stopped, that is, the relay 3
When the switch 9 is deenergized, the normally closed contact 41 is closed and the timer 42 starts counting time. and t ₂ hours has elapsed timer 4
When the normally open contact 40 is closed, the relay 39 is energized and the circulation pump 44 is started. At the same time, the contact 41 is opened, the timer 42 is restored, and the contact 40 is also opened. However, as described above, the relay 39 is self-held by the contact 35, and the circulating pump continues to operate. On the other hand, the timer 37 starts counting simultaneously with start of the circulating pump so contact 36 is closed by the stop of water supply Pont <br/> flop, normally closed contact of the as well as a timer 37 and t ₁ hour has elapsed 38 Opens, relay 3
9 is deenergized and the circulation pump 44 stops.

The switch 45 is for continuously operating the circulating pump, and is for long-time operation when the water in the tank is newly replaced. In this example of the control circuit, t ₁ and t _{3 in} FIG.
Although the timer is used to make do with the timer, it is obvious that the timers may be used separately. Naturally, similar control can be performed by a semiconductor logic circuit or the like.

[0017]

According to the apparatus for magnetizing water of the present invention, harmful impurities are significantly reduced by circulating water in a strong magnetic field many times at a particularly high flow rate, compared with a conventional apparatus of this type. Is now possible. Further, since the device is integrated and has a water sending function in itself, it can be provided in the middle of a water supply pipe regardless of an installation place and used. Also, the water in the tank can be used when water is cut off for a time due to water supply restrictions or in case of emergency. In particular, in the event of a disaster caused by an earthquake, electricity was restored immediately, but in some cases it took a long time to restore the water supply.In such a case, the device of the present invention maintained the water quality for a long time by magnetizing the water in the tank. Can be used while doing.
