Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for producing drinking water in which the dissolved oxygen concentration of water before treatment is lowered.

[0002]

2. Description of the Related Art In general, the concentration of dissolved oxygen contained in tap water and the like is almost constant. p. It is around m. This dissolved oxygen is molecular oxygen and maintains an equilibrium state in vapor pressure with oxygen in the air,
It is constantly maintained at a constant value. In order to control the dissolved oxygen concentration, deoxidation is conventionally performed with a deoxidizer such as iron ions. It is also known to use an oxygen-selective permeable membrane capable of specifically selecting oxygen. Further, there is known a device that applies far infrared rays and magnetic lines of force to tap water.

[0003]

The control of dissolved oxygen by adding a deoxidizing agent is not suitable for drinking water due to the problem of solubility of the agent itself and side effects of the agent. Further, when dissolved oxygen is controlled using an oxygen-selective permeable membrane, it is rarely used except in special cases due to difficulty in use and economic factors. Further, a known device for imparting far infrared rays and magnetic lines of force to tap water is one in which far infrared rays are not sufficiently imparted to untreated water, and a magnet is in direct contact with the water, which is effective. There was a problem in terms of health and hygiene. It is an object of the present invention to solve such problems and to provide a better, more hygienic and efficient potable water producing apparatus simply and economically.

[0004]

According to the present invention, a far-infrared ray and a magnetic line of force are applied to water before treatment by using a ceramic ball and a magnet so that the dissolved oxygen concentration is about 6 p. p. In the tank, a portion for accommodating a ceramic ball and a magnet is provided, and the ceramic is accommodated between punching boards so that the occupancy rate is about 80% and sufficient for water before treatment. In addition to providing far infrared rays efficiently, a magnet is provided around a running water pipe through which water before treatment passes so that the magnet does not come into direct contact with the water.

EXAMPLES Experimental Example As ceramics, SiO ₂ (45.8%), Al ₂
O ₃ (43.5%), Fe ₂ O ₃ (4.5%), TlO
₂ (2%), K ₂ O (1.6%), Na ₂ O (1.4
%), CaO (0.7%), and MgO (0.3%) formed in a ball shape. This ceramic ball has far-infrared characteristics as shown in FIG.

The above ceramic balls and magnets are provided in a tank having an inflow / outflow port, and tap water is supplied from the inflow port at a rate of 10 min / min.
A liter of water was flowed in to bring the tap water into direct contact with the ceramic balls and indirectly through the magnetic poles between the N and S poles of the magnet so that the lines of magnetic force could be obtained. Thus, the dissolved oxygen concentration of the drinking water flowing out from the outlet was measured. Table 1 shows the results. The magnets have magnetic field strengths of 200, 400, 500, 90.
Measurements were made in each case using those of 0, 1300 and 1600 gauss.

[0007]

[Table 1] When the graph of FIG. 2 is created based on this Table 1, the dissolved oxygen concentration of drinking water is decreasing, as is clear from this graph. It should be noted that the dissolved oxygen concentration remarkably appears at about 500 gauss or more, and is 6 p. p. It is less than m.

An apparatus for reducing the dissolved oxygen concentration of the tap water is shown in FIGS. What is shown is a vertical tank (1) type, in which a large number of ceramic balls (4) are housed in a lower tank (3) supported by legs (2) in a stacked state, and an upper tank (5) is also included. A flowing water pipe (6) fixed by a support plate (17) is provided inside, and a magnet (7) is provided around the flowing water pipe.
I am wearing.

The ceramic balls (4) are usually 13 to 1
A punching board having a diameter of about 5 mm and a large number of these holes (9) (the illustrated one has a diameter of 8 mm is used, but other diameters may be used). We support in (8). Cleaning, replacement, inspection, etc. of the ceramic balls are performed from the inspection port (10).

The magnet provided on the outer periphery of the running water pipe (6) is formed in a plate shape as shown in the figure, and the magnet is laminated in three stages or other stages, and the outer periphery thereof is formed by the band (1).
Although fixed in 3), the magnet may be formed in a circular shape so as to cover the outer circumference of the running water pipe, or the magnet may be fixed with a contact agent. The magnetic poles of the laminated magnets may be arranged as shown in FIGS. 6 to 8 or other arrangements, but in any case, they are formed so that the magnetic force lines are given to the tap water flowing through the water pipe. To be done.

The flowing water pipes (6) can be formed in an appropriate number, and can be provided, for example, as shown in FIGS.

Tap water (water before treatment, source water) flowing in from the inflow port (14) is the hole (9) of the punching board (8).
To the ceramic ball (4) directly through which the far infrared rays are given, and then passes through the flowing water pipe (6), at which time the magnetic field lines are generated by the magnet (7) provided on the outer circumference of the flowing water pipe. Is given and flows out from the outflow port (15). When the water comes in contact with the ceramic balls, the ceramic balls occupy about 80% of the space between the upper and lower punching boards, so that the ceramic balls float under water pressure and the contact area with the ceramic balls is increased. Increase. An intake / exhaust port (16) is appropriately provided in the tank.

In the illustrated example, tap water flows in from the lower part, but it may flow in from the upper part depending on the mounting condition of the tank, or the tank may be used horizontally. In addition, when the tap water was first applied to the magnetic field lines, better results were obtained than when the far infrared rays were first applied. The above device can be formed of a corrosion resistant material such as synthetic resin or stainless steel.

EFFECTS OF THE INVENTION Since the present invention is constructed as described above, the dissolved oxygen concentration of water before treatment is about 6 p. p. m
It is effective as drinking water because it brings about the effect of suppressing the abnormal occurrence of intestinal bacteria. Further, since the ceramic balls that radiate far-infrared rays are accommodated in a stacked state between the punching boards so as to occupy about 80% of the space, the ceramic balls float and move freely due to the inflowing water before treatment. The water is evenly contacted with the ceramic balls, and far infrared rays can be sufficiently and efficiently applied to the water. Moreover, since the magnet that gives the magnetic field lines to the water is provided around the running water pipe through which the water passes and is not in direct contact with the water, fine debris of the magnet is mixed into the water or the magnet is used for a long time. When used, it is efficient and hygienic as it does not deteriorate its function due to adhesion of water stains and water moss. Further, since it has a simplified structure as described above, it can be manufactured easily and economically.
