Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water treatment device which is directly connected to, for example, a tap for water.

[0002]

2. Description of the Related Art Conventionally, various types of water treatment devices have been proposed. In recent years, when water is passed through a magnetic field, the water is activated and it is said that this water is good for the human body. A water treatment device equipped with a magnetic device has been proposed.

[0003]

By the way, in a magnetic device, at least a pair of permanent magnets are made to face each other and water is allowed to pass through this gap.
The strength of the magnetic field is great. Moreover, these permanent magnets need to be arranged via spacers. Therefore, many permanent magnets cannot be arranged in the small flow path of the water treatment device, and when many permanent magnets are arranged, the water resistance is so large that a sufficient flow rate cannot be maintained. . On the other hand, if a pair of permanent magnets and a large gap are provided, the flow rate of water can be secured, but the strength of the magnetic field is not sufficient.

Therefore, the present invention has an object to provide a magnetic device in a water treatment device which has a large flow rate and is capable of sufficiently activating water, although a large number of permanent magnets are arranged in the flow path. And

[0005]

In order to achieve the above-mentioned object, the present invention uses a magnetic device in a water treatment device to cause raw water supplied from a raw water supply port to pass through a water treatment material layer in a cartridge. After performing the water treatment, the treated water is taken out from the outflow pipe, and the magnetic device provided in the water supply passage activates the water. Three or more spherical permanent magnets and plate-shaped permanent magnets are provided in a case made of a non-magnetic material having a case body having a hole and fitted in the water supply passage and a cap having a plurality of water passage holes. The configuration is such that they are arranged alternately.

The cartridge 20 is made of synthetic resin and comprises a bottomed case and a lid provided with a water guide tube 21, and a filter (not shown) is attached to the lower end opening of the water guide tube 25. An opening having a filter is provided on the shoulder of the lid, and the portion of the case excluding the water conduit 21 is filled with a water treatment material S such as activated carbon to cover the opening of the case. It is sealed in the body.

The cover 30 is made of stainless steel or the like and covers the cartridge 20 while keeping a predetermined space (passage). As shown in FIG. 4, the neck portion from which the water guiding pipe 21 projects at the center of the top. 31, the lower outer periphery is adapted to be fitted to the cylindrical side wall 2 of the base 1.
Further, the collar portion 5 of the locking piece 4 is provided on the lower outer periphery of the cover 30.
The protrusions 33 are provided with four protrusions 32, which are engaged with the groove 5a formed below, at equal intervals. However, protrusion 3
The length of 2 in the circumferential direction is smaller than the length of the locking piece 4. Therefore, after inserting the annular U-packing P into the packing mounting groove 3 and placing the cartridge 20 in the center of the upper surface of the base 1, the water conduit 21 is attached to the neck portion 3.
1 and project the protrusion 32 of the cover 30 from the locking piece 4
The cartridge 20 and the cover 30 are attached to the base 1 by being positioned and rotated.

The cap 35 has a fixing portion 36 which is screwed to the neck portion 31 of the cover 30 via packing,
It is rotatably attached to the fixed portion 36, the lower end is connected to the water conduit 21 of the cartridge 20 via a packing (not shown), and a shaft portion 38 having a water passage 39 therein is provided so as to project. It comprises a rotating portion 37 having an outflow pipe 41 connected to a water passage, and a mounting portion 40 for a magnetic device 60 described below is provided above the water passage 39 of the shaft portion 38.

As shown in FIG. 5, the pretreatment filter 45 has a synthetic resin cylinder 46 having a large number of passage openings 47.
And a flanged plug body 49 mounted in the opening of the hole 48 of the tubular body 46, a knob 51 mounted in a recess 50 of the plug body 49, and a filter 53. And
After attaching the flanged plug body 49 to one end of the cylindrical body 46, a filter 53 made of, for example, a non-woven fabric is laminated on the outer peripheral portion and inserted into the pretreatment filter charging section 6 provided in the base 1. Then, the end portion of the tubular body 46 is fitted to the outer periphery of the annular protruding portion 7, and then the protrusion of the knob 51 is press-fitted into the recess 50 of the plug body 49 and rotated, and the screw 52 is provided on the base 1. It is to be screwed into a screw.

The magnetic device 60 is fitted in the magnetic device charging portions 9 and 40, and is composed of a bottomed cylindrical body having a large number of holes 62 at the bottom as shown in FIGS. A case body 61, a cap 64 having a large number of holes 65 that fits into an opening 63 of the case body 61, a spherical first permanent magnet body 66, and a disc-shaped second permanent magnet body 67.
The case body 61 and the cap 64 are made of a non-magnetic material. Then, in the case body 61,
As shown in the figure, for example, three first permanent magnet bodies 66 each are provided.
And the second permanent magnet body 67 are alternately enclosed, and each permanent magnet 6
A strong magnetic field is formed between 6 and 67. In addition,
The first permanent magnet body 66 may be coated with resin on its surface to prevent rusting.

Because of the above-mentioned structure, when a water tap (not shown) is opened, raw water (tap water) flows into the pretreatment filter charging section 6 from the raw water supply port 10 provided in the base 1.
The suspension of large particles is removed through the filter 53 and the passage port 47, enters the cylindrical body 46, and passes through the magnetic device 60. As described above, the magnetic device 60 has spherical and disk-shaped first and second permanent magnets 66 and 67 arranged alternately, and a large magnetic field is formed because the magnet spacing is small, and Since the flow resistance is relatively small due to the existence of the spherical permanent magnet 66, the raw water is activated and then passes between the cover 30 and the cartridge 20 to open the opening 2.
After flowing down from the inside of the cartridge 20 from 4 to 4, it is discharged from the discharge pipe through the water guiding pipe 25 and the magnetic device 60 provided in the cap 35. Although the magnetic devices 60 are installed at two locations in the above embodiment, only one of them may be installed.

[0015]

As is apparent from the above description, the magnetic device according to the present invention comprises spherical and plate-shaped permanent magnet bodies housed in a case made of a non-magnetic material, and three or more magnet bodies each. Since they are alternately arranged in the case, they can be assembled in advance. Moreover, without using a spacer, the first
Since the permanent magnet body is spherical, it has less resistance to water, the distance between the permanent magnets is small, and it is in a state orthogonal to the flow direction of water, so that water can be efficiently activated. Play.
