Description

  The present invention relates to a domestic water treatment apparatus that activates tap water.

  Conventionally, various water treatment techniques have been proposed for water quality according to the purpose of use by physical and chemical methods. There is a treatment technique for imparting some energy to water and activating the water to have a sterilizing power and a cleaning function.

  For example, a water treatment apparatus is known in which a plurality of water flow pipes coated with a far-infrared radiation material are sandwiched and a plurality of permanent magnets are arranged so as to correspond to each other (see, for example, Patent Document 1).

  Moreover, the processing apparatus which manufactures a nanobubble containing active water by applying a magnetic field with respect to the microbubble containing water produced by mixing and shearing a liquid and gas is also known (for example, refer patent document 2).

Japanese Patent No. 2622911 Japanese Patent No. 4851400

  The water treatment apparatus of Patent Document 1 allows water to be treated to pass through magnetic lines of force to increase the energy level of water by electronic excitation, and further, the far-infrared radiation material thermal radiator resonates with the absorption wavelength of water. In this way, water molecules are atomized. When charged water containing finely divided water molecules comes into contact with the wall in the water pipe, dissolution of deposits such as red rust on the wall proceeds.

  When tap water is used for daily life, it is not preferable that the deposits in the pipe are removed in a short time and dissolved in a large amount of tap water. However, in the case of tap water that has been subjected to magnetic active water treatment using magnetism, the size of the molecule is about one-tenth that of ordinary tap water, and far infrared rays are applied to tap water. It is considered to be the same level, and the dissolution of the deposit gradually proceeds and gradually dissolves in tap water. Therefore, it can be said that the water treatment apparatus of Patent Document 1 is optimal for maintaining the inside of a water pipe in a sanitary manner. However, when cleaning is performed using tap water as active water, an immediate effect cannot be expected.

  Therefore, when obtaining the function as active water so that a higher effect in detergency and dissolving power can be obtained in tap water, it is better to further atomize water molecules. The effect is enhanced by mixing the gas into microbubbles. In this case, if gas pressure is directly applied to the water pipe to mix the gas into the tap water, the water system will be affected. In Patent Document 2, the tap water is stored in the reserve tank and then mixed with gas and liquid. Yes.

  However, gas-liquid mixing in which tap water is reserved in the tank and pressure is applied to the tank increases the size of the apparatus, making it unsuitable for water treatment apparatuses used for home use and increasing the cost.

  In view of the above, the present invention aims to provide a downsized water treatment apparatus that is optimal for household use in tap water activation treatment that enhances the effects of detergency and dissolving power.

  In order to solve the above-mentioned problem, a water treatment device that is directly connected to a tap water supply pipe sent to a household, and is included in the tap water that is provided in the middle of the water supply pipe and is sent at a tap water pressure. A plurality of permanent magnets arranged so as to correspond to each other with a fine bubble generating part having a nozzle for generating cavitation bubbles from the air generated and at least one of the water supply pipes on the inlet side or the outlet side of the fine bubble generating part It is characterized by having.

  And it has a cover case in which the fine bubble generating part and the permanent magnet are stored, and is used as a domestic water treatment device unit that can be connected by a flange in the middle of a water supply pipe that passes water from a water pipe or an elevated water tank. Is preferred.

  And disposing the far-infrared radiation material outside the water supply pipe in the cover case makes it possible to make the bubbles more effectively finer due to the synergistic effect of magnetism and far-infrared rays.

  An embodiment of the nozzle is hollowed out in a substantially conical shape so that the diameter continuously increases from the minimum hole to the upstream side and the downstream side, with the minimum hole having the minimum cross-sectional diameter as a boundary. It consists of a first water passage and a second water passage. The tap water supplied with the tap pressure becomes a high pressure in the first water passage chamber and becomes a low pressure when released from the minimum hole, and fine cavitation bubbles are generated by the boiling phenomenon.

  In this case, it is preferable that the inlet side has a water intake port that takes in water at an angle inclined with respect to the axis of the nozzle. As a result, water is introduced from an oblique direction with respect to the axial direction by tap water pressure, and the pressure is increased while rotating the inner wall of the first water flow chamber in a spiral manner at a high speed, so that the second passage through the minimum hole portion. Released into the water chamber.

  Another embodiment of the nozzle includes a plurality of water passage portions arranged along an axial direction, and the water passage portion has a cylindrical shape at a central portion, and upstream and downstream sides at both ends, respectively. A taper portion is formed so as to continuously expand the diameter. As a result, the tap water supplied by the tap pressure is diverted to each water passing portion and the inlet side is constricted by the taper portion, so that the pressure becomes high, and when it is discharged from the outlet side, the pressure decreases rapidly. As a result, fine cavitation bubbles are generated by the boiling phenomenon.

  In the domestic water treatment apparatus according to the present invention, since the fine bubbles are contained in the tap water by the air contained in the tap water directly connected to the tap water, the active water is generated without increasing the size of the apparatus. And the function of the detergency / solvent power which water originally has can be improved by performing the magnetic active water process which passes a tap water through the inside of a magnetic field, and converting into a microbubble containing magnetic active water.

Side surface sectional drawing of the domestic water treatment apparatus which concerns on this invention is shown. (A) shows an external perspective view from the upstream side of the fine bubble generating part, and (b) shows an external perspective view from the downstream side of the fine bubble generating part. (A), (b), (c) shows the top view from the upstream of the intake part of a microbubble generation | occurrence | production part, a side view, and the top view from a downstream, respectively. A schematic explanation of the action in the nozzle is shown. The other structural example of a nozzle is shown with a side view. The part in which a permanent magnet is attached in a water treatment apparatus is shown with sectional drawing from the direction orthogonal to the flow of tap water.

  Embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a configuration of a water treatment apparatus 1 according to the present invention in a side sectional view, and is arranged in the middle of a water supply pipe 3 that guides water from a water pipe, an elevated water tank, etc. to a faucet.

  The water treatment apparatus 1 includes a fine bubble generating unit 4 that forms fine bubbles by generating cavitation in air included in tap water that is provided and sent in the middle of a water supply pipe 3, and a fine bubble generating unit. 4 and a plurality of permanent magnets 5 disposed so as to correspond to each other with a water supply pipe 3 connected to the outlet side of 4 being accommodated in the case 2 and unitized. The left side of the water supply pipe 3 is the upstream side in the drawing, and is divided into an upstream pipe part 3A and a downstream pipe part 3B on the way, and the water treatment device 1 is connected therebetween.

  The fine bubble generating part 4 includes a tubular member 11 located on the upstream side, a water intake part 12 fitted in the inlet opening of the tubular member 11, a cylindrical member 13 disposed downstream and larger in diameter than the tubular member 11, and a column And a nozzle 14 having a shape. (A), (b) of FIG. 2 has shown the external perspective view from the upstream and downstream of the fine bubble generation | occurrence | production part 4 in the state which removed the water intake part 12, respectively.

  The tubular member 11 has a threaded portion 11 a on the outer periphery thereof and is connected by screwing inserted into the upstream tube portion 3 </ b> A of the water supply tube 3. Moreover, the cylindrical member 13 has the thread part 13a in the inner periphery, and is connected with the front-end | tip of the downstream pipe part 3B of the water supply pipe 3 inserted by screwing. An annular rubber packing 17 is fitted on the outer periphery of the tubular member 11, and when the tubular member 11 is inserted into the upstream pipe portion 3 </ b> A, the annular end surface of the upstream pipe portion 3 </ b> A is interposed between the rubber packing 17 and the cylindrical member. 13 end faces are contacted.

  The outer diameter of the nozzle 14 is substantially equal to the inner diameter of the tubular member 11, and a round hole having a diameter substantially equal to the outer diameter of the nozzle 14 is formed at the center of the bottom surface of the cylindrical member 13. Therefore, the nozzle 14 is held in a state of being inserted into the tubular member 11 through the bottom surface of the cylindrical member 13.

  In the nozzle 14, a central hole is a minimum hole 141 having a minimum cross-sectional diameter, and the nozzle 14 is hollowed out in a substantially conical shape so that the diameter increases from the minimum hole 141 to the left and right. A water portion 15 is formed. Therefore, the water flow portion 15 includes the first water flow chamber 15a having the shape in which the diameter of the cross section gradually decreases toward the minimum hole portion 141 along the water flow direction with the water intake portion 12 attached, and the minimum hole portion. 141 and the second water flow chamber 15b having a shape in which the diameter of the cross section gradually increases along the water flow direction.

  The water intake portion 12 is formed of a disk-shaped member, and as shown in FIG. 3A, four round hole-shaped water intake ports 12a are provided concentrically on the plane. As shown in the side view of FIG. 3 (b), this round hole is formed so that the central axis in the depth direction is inclined with respect to the central axis direction of the nozzle 14, and thus each intake port 12a is formed in FIG. As shown in c), the shape is an oblique cylinder.

  Since each intake port 12a has the shape of a slanted cylinder, the tap water pressurized and fed to each intake port 12a by tap pressure is blown out toward the inner wall of the first water flow chamber 15a. As shown in the figure, the speed is increased as it approaches the minimum hole 141 while spirally turning the inner wall, and is discharged from the minimum hole 141 to the second water passage 15b.

Then, the water blown out from the first water flow chamber 15A of the nozzle 14 at a high pressure undergoes a rapid pressure drop in the second water flow chamber 15b, and countless fine cavitation bubbles are generated due to the boiling phenomenon, It discharges | emits to the downstream pipe part 3B. The lower limit of the tap water pressure is 1.5 kgf / cm ² (0.15 MPa), and the nozzle 14 allows the air contained in the tap water supplied to ordinary households to be reduced only by the tap water pressure. , Make water containing bubbles refined by cavitation. The ideal tap water pressure in this case is 2.0 to 4.0 kgf / cm ² (0.2 to 0.39 MPa).

  The permanent magnet 5 is disposed on the outer periphery of the downstream pipe portion 3A so that the S pole and the N pole face each other, and is held by a pressing member 18. FIG. 6 shows a portion where the permanent magnet 5 is attached in the water treatment device 1 in a cross-sectional view from a direction orthogonal to the flow of tap water. For example, a 4000 gauss rare earth magnet is used as the permanent magnet 5. Therefore, when the water ejected from the nozzle 14 passes through the portion where the permanent magnet 5 of the downstream pipe portion 3A is disposed, it crosses the magnetic poles at right angles, and the water molecules undergo an electron excitation action due to the magnetization action. In response, the energy level is increased and magnetic activation is performed.

  In other words, since water contains ions and has electrical conductivity, energy conversion between water molecules occurs violently when exposed to a magnetic field. This is because water molecules are also polar, one of which is negatively charged (-) and the other is positively charged (+), and the charged high-energy particles are atomized by the magnetic field action. Thus, water molecules are activated.

Therefore, according to the above configuration, the magnetic activity is imparted to the fine bubble-containing water by applying a magnetic field to the fine bubble-containing water ejected from the fine bubble generation unit 4 and converted into the fine bubble-containing magnetically active water. can do. The microbubble-containing magnetically active water is said to have a very small cluster, and the water penetration, dissolution, cleaning, and purification are significantly activated.

  In the present embodiment, the permanent magnet 5 is arranged downstream of the fine bubble generating unit 4, but the permanent magnet 5 may be arranged upstream of the fine bubble generating unit 4. That is, tap water is first passed through a magnetic field to form magnetically active water, and then converted to fine bubble-containing magnetically active water by passing through the fine bubble generating unit 4.

  Furthermore, in this embodiment, the far-infrared radiation | emission material 16 is attached to the outer periphery of 3 A of downstream pipe parts cyclically. The far-infrared emitting material emits electromagnetic waves having a wavelength of 8 to 14 μm. This is substantially the same as the wavelength of water's frequency, and is absorbed to generate thermal energy, which activates water molecules by causing resonance (resonance) motion. The far-infrared radiation material 16 may be disposed on the inner wall of the case 2 as well as being applied to the water pipe 3.

  Various configurations are conceivable for nozzles that generate water containing bubbles that are refined by cavitation from air contained in tap water. FIG. 5 schematically shows the structure of the nozzle 20 having another shape for generating fine bubbles. The nozzle 20 is connected to the water supply pipe 3 at both ends by flanges 28, and a conical shape having a tapered portion 21 a continuously expanded toward the downstream is connected to the upstream water supply pipe 3. The jet part 22 which is provided with the intake part 21 which is a member and has a tapered part 22a continuously reduced in diameter toward the jet port 26 at the connection part with the downstream water supply pipe 3 It has.

  Between the intake part 21 and the ejection part 22, the some water flow part 26 is arrange | positioned along the axial direction of the nozzle 20. As shown in FIG. Each water flow portion 26 includes a cylindrical water flow hole 23 at the center, and tapered portions 24 and 25 formed by continuously expanding the diameter toward the upstream side and the downstream side, respectively, at both ends thereof. Is formed.

  The operation of the nozzle 20 will be described. When the tap water from the water supply pipe 3 is introduced into the intake portion 21, the nozzle 20 guides the water flow to each water flow portion 26 by the tapered portion 21 a. Therefore, the tap water is diverted to increase the pressure, and in each of the water passing portions 26, the diameter of the inlet side is reduced toward the downstream side by the tapered portion 24, so that it is narrowed around the inlet side. The vortex is generated and the water collides violently, so that the pressure is further increased and introduced into the water passage hole 23.

  And the water which passed the water flow hole 23 is spread | diffused by the taper part 25, and becomes a low voltage | pressure, and countless fine cavitation bubbles generate | occur | produce by a boiling phenomenon. And the tap water containing a cavitation bubble is collected by the ejection part 22, and is ejected from the ejection port 27 through the taper part 22a.

  The water treatment apparatus 1 having the above-described configuration is directly connected to a tap water supplied to a general household, and the air contained in the tap water is microbubbled by a cavitation action only by the tap water pressure. And although the water treatment apparatus 1 is arrange | positioned downstream of a water meter, the piping distance from a water meter to a faucet is about 15 meters on average. In this case, fine bubbles cannot be visually observed, but fine bubbles are formed even at the end of a 15-meter pipe by detecting the reflected light from the bubbles by applying a laser to the water to be treated with a laser pointer in a dark place. It is confirmed that

  Then, by passing the tap water through the magnetic field and converting it into the magnetically active water containing fine bubbles, it is possible to further improve the functions of the cleaning power and the dissolving power inherent in the water by about 50%. Moreover, since it is directly connected to the water supply, it is safe and secure that nothing other than tap water is contained.

The main effects when using the magnetic active water containing fine bubbles are as follows.
(1) Thermal bathing and heat retention effects by promoting blood circulation in peripheral blood vessels and increasing blood flow (2) Cleaning effects inside living bodies and water pipes such as human bodies and animals (3) Growth effects on plants and fish (4) Due to mild bubbles Massage effect
