Abstract
A water purifier includes a filter having a cylindrical chamber formed with an inner wall, an outer wall and a bottom. A ceramic layer of granular ceramic particles and at least a pair of magnetic layers each comprising an annular magnet and magnetite particles are provided above or below the ceramic layer in the chamber. The annular magnets are arranged in such a way that the same polarities of adjacent annular magnets are facing each other, and the direction of the magnetic lines of force is parallel to the direction of flow of the water. Water molecules are activated while passing through the magnetic field produced by the magnetic layers of annular magnets and magnetite particles which are magnetized by the annular magnets.
Description
- This invention relates to a water purifier and, more particularly, to a water purifier having a magnetic field generation device such as a permanent magnet.
- Known in the art of devices for purifying tap water are devices which utilize granular activated carbon, etc. to remove residual chlorine and other impurities in the tap water. Also known are devices which have an additional function of adjusting the water quality such as pH by electrolytic treatment or by using an ion exchange resin. Also recently developed are devices which utilize infrared radiation or a magnetization treatment to activate water molecules.
- U.S. Pat. No. 5,628,900 discloses a water purifier including a filter having a cylindrical housing formed with a water inlet at one end and a water outlet on the other end and containing a granular activated carbon layer and a ceramic layer comprising granular ceramic, a magnetite layer comprising broken pieces of magnetite in a layer and provided at least above or below the ceramic layer, and annular magnets provided above and below the ceramic layer in such a manner that these annular magnets coincide with each other in the sense of magnetic lines of force and that the direction of the magnetic lines of force is parallel to the direction of flow of water. Water molecules are activated while passing through the magnetic field produced by the annular magnets and the magnetite layers which are magnetized by the annular magnets.
- It is an object of the present invention to provide an improved water purifier capable of applying a magnetic field to water to be treated more effectively than the above described prior art water purifier and thereby removing residual chlorine in water to be treated more effectively.
- In the present invention it has been found that the effectiveness of a magnetization treatment to activate water molecules depends on two major factors—how effective the water flow is through the magnetic field and the speed of water flow.
- An annular magnet with or without a certain amount of magnetite forms a magnetic layer having a fixed strength of the magnetic field. The density of the magnetic field depends on the cross-section of the magnetic layer—the larger the cross section, the lower the density of the magnetic field. Vise versa, the smaller the cross section, the higher the density of the magnetic field.
- For a fixed strength of the magnetic field of a magnetic layer—the density of the magnetic field is inversely proportional to the cross-section of the magnetic layer.
- The effectiveness of a magnetization treatment to activate water molecules is proportional to the density of the magnetic field.
- For a fixed water flow rate, the larger the cross section of the water flow, the lower the speed of the water flow. Vice versa, the smaller the cross-section of the water flow, the higher the speed of the water flow.
- For a fixed water flow rate—the speed of the water flow is inversely proportional to the cross-section of the water flow.
- These may be expressed by the formula E∝1/C2 Where:
- E is effectiveness of a magnetization treatment, and
- C is cross section of the magnetic layer.
- The effectiveness of a magnetization treatment to activate water molecules is also proportional to the speed of the water flow.
- For an annular magnet with or without a certain amount of magnetite which forms a magnetic layer, if the cross section of the magnetic layer is reduced by half such that the density of the magnetic field is double and the speed of water flow is double, then the effectiveness of a magnetization treatment to activate water molecules is four (4) times better.

FIG. 1 is a vertical cross-sectional view showing a water purifier of a preferred embodiment of the present invention; -
FIG. 2 is a vertical cross-sectional view showing a water purifier of the prior art; and -
FIG. 3 is a vertical cross-sectional view showing a water purifier of the present invention as a preferred embodiment of a shower filter. -
FIG. 1 is the vertical cross-sectional view of a preferred embodiment of water purifier which includes a magnetic field generation device in accordance with the present invention. The water purifier includes a generallycylindrical housing 10, having a longitudinal axis a, anouter wall 31, aninner wall 32 and abottom 33 which define achamber 34 therein. A first magnetic layer 101, a secondceramic layer 102, a thirdmagnetic layer 103, a fourthceramic layer 104, a fifthmagnetic layer 105, a sixthceramic layer 106 and seventhmagnetic layer 107 are positioned within thechamber 34. - In the preferred embodiment of the invention, each
magnetic layer FIG. 1 , the S pole of annular magnet 40-1 is facing the S pole of annular magnet 40-2, the N pole of annular magnet 40-2 is facing the N pole of annular magnet 40-3, and the S pole of annular magnet 40-3 is facing the S pole of annular magnet 40-4. - Each
ceramic layer - Water flows from
top 30 throughlayers bottom 33. Vice versa, water can also flow in the reverse direction from thebottom 33 throughlayers top 30. - Two pairs of magnetic layers are shown in
FIG. 1 . However, the arrangement is not limited to two pairs of magnetic layers and can be any number of magnetic layers as desired. Likewise, the number of ceramic layers can also be varied. -
FIG. 2 is a vertical cross-sectional view of a prior art water purifier which also includes a magnetic field generation device. The purifier includes ahousing 20, a firstmagnetic layer 201, a second ceramic layer 202, a third magnetic layer 203, a fourthceramic layer 204, a fifthmagnetic layer 205, a sixth ceramic layer 206 and a seventhmagnetic layer 207. Thehousing 20 includes anouter wall 34 and abottom 36. - Each
magnetic layer FIG. 1 , the annular magnets are arranged in such a way that the same polarity of the adjacent annular magnets are facing each other. As illustrated inFIG. 2 , the S pole of annular magnet 40-5 is facing the S pole of annular magnet 40-6, the N pole of annular magnet 40-6 is facing the N pole of annular magnet 40-7, and the S pole of annular magnet 40-7 is facing the S pole of annular magnet 40-8. - Each
ceramic layer 202, 204 and/or 206 includes granular ceramic particles 60-4, 60-5 and/or 60-6 respectively. - Water flows from the
top 35 of the housing throughlayers bottom 36. Vice versa, water can also flow in the reverse direction frombottom 36 throughlayers top 35. - The annular magnets 40-1, 40-2, 40-3, 40-4, 40-5, 40-6, 40-7 and 40-8 are the same in
FIGS. 1 and 2 . The amount of magnetite particles 50-1, 50-2, 50-3, 50-4, 50-5, 50-6, 50-7 and 50-8 are also the same. However, the cross-sectional area ofchamber 10 is half of that ofhousing 20. - For the same water flow passing through
chamber 10 andhousing 20, the speed of the water flow passing throughchamber 10 is double the speed of water flow passing throughhousing 20. Due to each magnetic layer 10-1, 10-3, 10-5, 10-7, 20-1, 20-3, 20-5 and 20-7 having the same annular magnet and same amount of magnetite particles 50-1, 50-2, 50-3, 50-4, 50-5, 50-6, 50-7 and 50-8, and the cross-section ofchamber 10 being half the cross-section ofhousing 20, the density of the magnetic field of magnetic layers is double the density of the magnetic field ofmagnetic layers - Although the
magnetic layers chamber 10 are otherwise exactly the same as the magnetic layers of 201, 203, 205 and 207 ofhousing 20, the effectiveness of the magnetization treatment of the invention as shown inFIG. 1 to activate water molecules is four times better that of the prior art as shown inFIG. 2 - The water purifier of the invention is shown incorporated in a preferred shower filter as seen in
FIG. 3 . InFIG. 3 water flows through aninlet 12,tube 13,chamber 14,sediment filter 15,chamber 16,housing 17 and exits throughoutlet 18 as shown by the arrows. Thechamber 16 withouter wall 28 of for example a diameter of 2.2 inches (3.8 sq. in.) andinner wall 21 of for example a diameter 1.7 inches (2.27 sq. in.) thechamber 16 will have a cross-section of 1.53 square inches (3.8 sq. in-2.27 sq. in). Thehousing 17 withouter wall 28 of also for example a diameter of 2.2 inches will result in a cross-section of thehousing 17 of 3.8 square inches. If the same magnetic field layer is put inchamber 16 instead ofhousing 17, the effectiveness of the magnetization treatment inchamber 16 is 6.17 times (3.8×3.8/1.53/1.53) better than that inhousing 17. - It will be appreciated that although the water purifier has been shown in
FIG. 3 as a shower filter, that the purifier may constitute or be part of any one of a variety of water treatment filters or assemblies other than shower filters. - Although pieces or particles of magnetite are shown and described as forming the magnetic layers together with the annular magnets, the magnetite may be eliminated and just the annular magnets relied upon to provide the magnetism in the magnetic layers without departing from the present invention.
- It will also be understood that the preferred embodiments of the present invention as have been described are merely illustrative of the principles of the present invention. Numerous modifications may be made by those skilled in the art without departing from the true spirit and scope of the invention.
