Description
FIELD OF THE INVENTION
The present invention relates to an apparatus for purifying water, and particularly for reforming hard water into soft water, and preferably used for bactericidal or antibacterial purpose of microbes in water, in particular, Legionella, and more specifically it relates to a water purifying apparatus for using water preferably as non-drinking water, such as water for washing hair, washing face, bathing, or showering (hereinafter called household water).
BACKGROUND OF THE INVENTION
As has been well known, various types of water purifying apparatus have been developed. Among those on market, activated carbon, ion exchange resin film, a kind of granite porphyry (so called “Bakuhan-seki” in Japanese) and the like are used as the filter medium. They are commercially available as the means for purifying drinking water to be so-called sweet water.
SUMMARY AND OBJECTS OF THE INVENTION
Aside from drinking water, a huge volume of household water has been consumed. The household water is highly demanded to be purified for the purpose of not only health and beauty, but also reformation from hard water to soft water and prevention of infection of the body by Legionella and other bacteria. By the related art using such filter medium, it was not suited or not sufficient for reforming the household water from hard water to soft water, and there has been almost no effective substance except chlorine compounds for the bactericidal or antibacterial purpose of Legionella.
It is hence an object of the invention to present a water purifying apparatus, not only capable of purifying water, but also preferably capable of providing water with buffering property (buffering effect), that is, making water mild (less stimulating), reforming household water from hard water to soft water, and having bactericidal or antibacterial effect.
The water purifying apparatus is the one for passing water into the purifying material provided in a hollow container, and the purifying material is composed of water-soluble non-crystalline material and activated carbon, and the ratio by weight thereof is about 1:1.5.
The water-soluble non-crystalline substance is a bulky material.
The composition of the water-soluble non-crystalline material includes 5.00 to 30.0% of silica, 7.00 to 30.0% of boron, 3.00 to 25.0% of sodium, and 0.30 to 1.80% of silver.
The composition of the water-soluble non-crystalline material includes 12.00 to 60.0% of silica, 6.00 to 50.0% of sodium, and 0.30 to 1.80% of silver.
The composition of the water-soluble non-crystalline material includes 12.00 to 60.0% of silica, 6.00 to 50.0% of calcium, and 0.30 to 1.80% of silver.
The composition of the water-soluble non-crystalline material includes 12.00 to 60.0% of silica, 6.00 to 50.0% of potassium, and 0.30 to 1.80% of silver.
The hollow container is formed by coupling a first case and a second case.
The hollow container is composed of an accommodating body having a lid forming multiple water passing holes at both ends.
The purifying material is put in an accommodating bag made of water permeable cloth or the like.
The hollow container is disposed in a water channel.
The hollow container is disposed in a shower head main body.
An amorphous material is used as the water-soluble non-crystalline material contained in the water purifying apparatus for purifying water, which will be described in detail. Generally, viscosity of a molten material increases as the temperature declines, and therefore when cooling quickly from molten state, the state of disorderly distribution of atoms is suddenly transformed into an immobile state of atoms at high viscosity. By such quenching process, the substance to be crystallized by the ordinary method is transformed into the substance where atoms are disorderly arranged.
Such substance is generally called an amorphous. The amorphous substance has a characteristic property not obtained in the conventional crystalline substance due to irregularity of arrangement of atoms. Soft magnetic characteristic, high corrosion resistance, and high strength are amorphous properties excellent also from the practical viewpoint. In order to make use of such amorphous characteristics, so far, applications have been attempted in the fields of magnetic core, magnetic filter, magnetic shield, sensor, strength material and compound material. The invention makes use of the amorphous characteristics of the water purifying material.

DETAILED DESCRIPTION OF THE INVENTION
A first embodiment of the invention is described in detail below, referring to the accompanying drawings. In
FIG. 1
to
FIG. 4
, a water purifying apparatus
12
is directly disposed on the way of the water channel.
Herein,
FIG. 1
is a sectional view of a water purifying apparatus
12
containing no water-soluble non-crystalline substance
13
as a purifying material in a hollow container
14
, which is disposed directly on a water service pipe
1
.
FIG. 2
is an exploded perspective view of the water purifying apparatus
12
containing the water-soluble non-crystalline substance
13
as the purifying material, which is disposed on the water service pipe
1
.
FIG. 3
is a sectional view of the water purifying apparatus
12
disposed on the way of the water service pipe
1
, which allows household water to pass therethrough.
In
FIGS. 1
,
2
and
3
, the hollow container
14
has a hollow front case
2
and a hollow rear case
3
. The front case
2
has a threaded portion
5
in the inner peripheral surface at its one end. The rear case
3
has a threaded portion
6
in the inner peripheral surface at its one end. Thus, the threaded portion
5
of the front case
2
and the threaded portion
6
of the rear case
3
are coupled together. The front case
2
is provided with an anti-slipping portion
4
on the threaded portion
5
.
The other end of the front case
2
has an extended portion
7
. The extended portion
7
constitutes a flow outlet
10
having a convex section for passing household water from the container
14
into the water service pipe
1
. The outer peripheral surface of the extended portion
7
has a threaded portion
9
by which the front case
2
is connected with the water service pipe
1
.
The other end of the rear case
3
has an extended portion
8
. The extended portion
8
constitutes a flow inlet
11
having a convex section for passing household water from the container
14
into the water service pipe
1
. The outer peripheral surface of the extended portion
8
has the threaded portion
9
by which the front case
2
is connected with the water service pipe
1
.
The hollow portion of the hollow container
14
contains the purifying material. When the front case
2
and the rear case
3
are combined, the purifying material is set in the space defined by the front case
2
and rear case
3
. In this way, the water purifying apparatus having the hollow container
14
is completed by coupling the threaded portion
5
of the front case and threaded portion
6
of the rear case.
Further, the mounting threaded portion
9
formed on the outer peripheral surface of the flow inlet
11
provided at one side of the container
14
of the water purifying apparatus
12
, and the mounting threaded portion
8
formed on the outer peripheral surface of the flow outlet
10
provided at the other side are coupled to the water service pipe threaded portion formed at an opening of the water service pipe
1
, respectively. Hence, the water purifying apparatus
12
is disposed on the way of the water service pipe
1
.
Thus, the household water flowing in from one water service pipe
1
flows into the water purifying apparatus
12
through the flow inlet
11
. The household water flowing into the water purifying apparatus
12
is brought into contact with the water-soluble non-crystalline substance
13
as the purifying material, and flows out into the other water service pipe
1
through the flow outlet
10
. Consequently, the hard household water flowing into the water purifying apparatus
12
from one water service pipe
1
is brought into contact with the water-soluble non-crystalline substance
13
in the water purifying apparatus
12
. Upon contact, ions are released into water such that the household water is reformed into soft water. Then the soft household water flows out from the water purifying apparatus
12
, and flows into the other water service pipe
1
.
FIG. 4
shows a modification of the water purifying apparatus shown in FIG.
1
. In the drawing, the water-soluble non-crystalline substance
13
is put into an accommodating bag
40
made of water permeable cloth or the like. The accommodating bag
40
is set in the hollow container
14
of the water purifying apparatus
12
. The drawing is a sectional view of passing water into the water purifying apparatus
12
disposed on the way of the water service pipe
1
. When the household water passes through bulk of the water-soluble non-crystalline substance
13
, it is dissolved to release its components into water. Thus, the bulk of the water-soluble non-crystalline substance
13
gradually becomes smaller. Even if the bulk of the water-soluble non-crystalline substance
13
becomes small enough to pass through the water service pipe
1
, it cannot flow out to the outside through the water service pipe
1
so long as it is contained in the accommodating bag
40
.

In
FIGS. 5
,
6
and
7
, the shower head main body
20
is composed of a shower head main body grip
22
, a flow outlet leading end
34
, and a water channel outlet
21
in the shower head main body. The shower head main body grip
22
and flow outlet leading end
34
can be separated from each other. That is, the shower head main body grip
22
has a connection threaded portion
24
in the inner peripheral surface of the flow outlet leading end
34
at one end. The flow outlet leading end
34
has a connection threaded portion
35
at a flow outlet leading end to be coupled with the connection threaded portion
24
of the shower head main body grip
22
at one end. The other end of the flow outlet leading end
34
has a plurality of shower head flow outlets
36
for discharging water.
The water purifying apparatus
12
has the container
26
and a water permeable lid
31
. The container

is mounted to the shower head main body grip
22
. Thus, the shower head incorporating the water purifying apparatus is completed.
Water is fed into the shower head main body
20
from a hose
25
. Accordingly, water is sent into the water purifying apparatus
12
through the water channel outlet
21
in the shower head main body. At this time, water passes in the bulk of the water-soluble non-crystalline substance
13
as the purifying material inserted in the water purifying apparatus
12
. At this time, since ions are released into water from the water-soluble non-crystalline substance
13
, water can be reformed into soft water from hard water. The reformed water passes through the flow outlet
32
of the lid
31
, and flows out in shower from the flow outlet

has a lid
56
provided with multiple flow-out holes
55
. The lid
56
has a mounting screw
57
for coupling to the upper lid
46
through screw.
The purifying material contained in the water purifying apparatus
12
is composed of water-soluble non-crystalline substance and activated carbon. The water-soluble non-crystalline substance
13
is bulky. The water-soluble non-crystalline substance is amorphous. As the amorphous material is used as the purifying material, the surface area contacting with water is wider. As a result, the amount of water in contact with the purifying material in the water purifying apparatus
12
per unit time can be increased. Thus, the dimensions of the water purifying apparatus
12
can be decreased.
When passing water into the shower head, the purifying material contains 20 to 30 g of the activated carbon relative to 20 g of the water-soluble non-crystalline substance having the following composition. The flow rate is 9.5 liters/min. Herein, the rate of composition of the water-soluble non-crystalline substance
13
is 5.00 to 30.0% of silica, 7.00 to 30.0% of boron, 3.00 to 25.0% of sodium, and 0.30 to 1.80% of silver. Herein, the activated carbon is present as a suspension.
By passing water with the purifying material contained in the shower head, and by passing water without containing the purifying material, the number of Legionella cells contained in water was compared. At the water flow rate of 9.5 liters/min, without passing through the purifying material, the Legionella cell count was 1.5×10, and when measuring by passing through the purifying material, no Legionella cell was detected. Moreover, by passing hard water, it was reformed into soft water.
Other components of the water-soluble non-crystalline substance as the purifying material inserted into the hollow container of the purifying apparatus are explained below.
That is, the composition of the water-soluble non-crystalline substance includes 12.00 to 60.0% of silica, 6.00 to 50.0% of sodium, and 0.30 to 1.80% of silver. Or the composition of the water-soluble non-crystalline material includes 12.00 to 60.0% of silica, 6.00 to 50.0% of calcium, and 0.30 to 1.80% of silver. Alternatively, the composition of the water-soluble non-crystalline material includes 12.00 to 60.0% of silica, 6.00 to 50.0% of potassium, and 0.30 to 1.80% of silver.
At the rate of this composition, as a result of comparison of Legionella cell count contained in water, when water was not passed through the purifying material, Legionella cells were detected, but when measured after passing through the purifying material, no Legionella cell was detected. By passing the hard water, moreover, it was reformed into soft water.
According to the water purifying apparatus of the invention, not only the water is purified, but also it presents a water purifying apparatus preferably capable of providing water with buffering property (buffering effect), that is, making water mild (less stimulating), reforming household water from hard water to soft water, and having bactericidal or antibacterial effect.
The water-soluble non-crystalline substance is bulky and formed as the amorphous, and hence the contact surface area with water is wider than in the related art such that the water purifying apparatus can be reduced in size.
