SYSTEM FOR PRODUCING OZONE WATER AND CONTROL METHOD THEREOF
BACKGROUND OF THE INVENTION
FIELD OF THE INVENTION
The present invention relates to a system for producing ozone water containing dissolved ozone in
which polluted water is reproduced as environmentally friendly. More particularly, the present
invention relates to an ozone water-producing system and its control method in which an ozone
water-producing apparatus can be flexibly used indoors or outdoors irrespective of the condition
of a flow channel. The condition of ozone generation is maintained in an optimum state so as to
improve the performance of the system in its entirety, as well as to mitigate the symptom of the
backflow of the ozone water due to a blocking of an outlet in the process of discharging. The
ozone water is preemptively detected to prevent deterioration of the system performance and ensure
stability in use.
BACKGROUND OF THE RELATED ART
In general, it is known that an ozone water-producing apparatus that can obtain ozone water
by mixing and dissolving ozone into water utilizes the strong oxidation effects of ozone for
the purpose of purification and disinfection. An ozone water-producing apparatus can be
classified as a pressurized injector type, a diffused air type or a venturi injector type, etc.,
depending on the ozone water-producing method.
Among them, a typical ozone water-producing apparatus of the pressurized injector type, as shown
in FIG. 1, includes an air pump 10 which sucks external air to provide to the apparatus as intake
air, an ozone generator 11 with an ozone-generating unit 12 for changing oxygen contained in the
air supplied from the air pump 10 into ozone to generate ozone, a mixer 14 for mixing the ozone
supplied from the ozone generator 12 with water supplied from a water source 13, a solenoid valve
16 installed in a water supply line 15 to control the flow of water supplied to the mixer 14 from
the water source 13, etc.
The ozone water-producing apparatus is configured in such a fashion that when the air pump 10
supplies air to the ozone-generating unit 12 compulsorily, the ozone-generating unit 12 changes
oxygen in the air into ozone. At this time, although a portion of the changed ozone is again
decomposed into oxygen, most of the ozone is pushed into the mixer 14 which, in turn, mixes the
ozone into water supplied from the water source 13 so as to discharge ozone water.
Accordingly, in such a pressurized injector type ozone water-producing apparatus, the ozone is
sucked into the mixer 14 by the negative pressure generated when water from the water source 13
passes through the water supply line 15 while pressure is generated by the air pump 10 so as to
discharge ozone water where gas and liquid are mixed, i.e., water which contains dissolved ozone.
The ozone water-producing apparatus requires various peripherals since maintaining a suitable degree
of water and ozone mixing relates to the performance of the apparatus. Examples of auxiliary devices
for stably and uniformly maintaining the mixing state of water and ozone to provide optimum water
containing dissolved ozone include a mixer for mixing ozone and water, an injector for generating a
negative pressure, a gas-liquid separator for controlling the amount of air introduced thereto or
separating gas and liquid, etc.
Examples of techniques for providing an improved ozone water-producing system through a modification
of the arrangement and structure of the ozone water-producing apparatus are described below. The
Korean Utility Model Registration No. 208,109, introduced by the applicant of the present invention,
discloses an apparatus for producing ozone water in which a solenoid valve (injector) is modified and
a bubble separator is installed in an ozone supply line connected to an inlet of a mixer. In this
system an increase in water pressure alone permits the inflow of ozone without an air pump, the
discharge of surplus ozone not mixed into the water is prevented and a reduction in the number of
components and miniaturization is achieved according to the absence of the air pump in the overall
construction. Also, various problems associated with re-use of the ozone including possible physical
harm to humans due to the ozone as well as breakage of the peripheral components are resolved.
Another Korean Utility Model Registration No. 203,244, introduced by the applicant of the present
invention, discloses an apparatus for producing ozone water in which a problem associated with security
of the length of a flow channel due to the additional installation of a solenoid valve and an injector
on the flow channel is overcome in such a manner that the flow channel length is shortened and an air
pump is replaced while obtaining suitable ozone water through an integrated application of the solenoid
valve and injector.
However, such conventional arts are directed to a modified structure of a flow channel for mixing
artificially generated ozone and water. Particularly, there has been a problem in that the use of air
containing foreign substances and moisture to generate ozone causes deterioration of the ozone-producing
efficiency.
In addition, there occurs a frequent blocking of an ozone water outlet during system operation. In
this case, the ozone water deviates from a normal flow path and flows backwards so that a mixed balance
between water and ozone is destroyed, simultaneously making the normal discharging of ozone water impossible.
As a result, along with a decrease in the entire flow channel performance, a user can be inconvenienced by
having the need to obtain maintenance and repair of the system from those highly skilled in the art.
Moreover, there has not been suggested a concrete approach for efficient control, a concrete system design
and an ozone water producing apparatus that can be easily and simply utilized in homes, public facilities
or the like.

SYSTEM FOR PRODUCING OZONE WATER AND CONTROL METHOD THEREOF
BACKGROUND OF THE INVENTION
FIELD OF THE INVENTION
The present invention relates to a system for producing ozone water. The invention is used to
dissolve ozone in polluted water and render it environmentally friendly. In particular, the present
invention relates to an ozone water-producing system and its control method in which an ozone
water-producing apparatus can be flexibly used indoors or outdoors irrespective of the condition
of a flow channel. The conditions of ozone generation are optimized to enhance performance and
prevent backflow of ozone water. The ozone water is monitored to prevent deterioration of the system
performance and ensure stability in use.
BACKGROUND OF THE RELATED ART
An ozone water-producing apparatus generates ozone water by mixing and dissolving ozone in water. The
strong oxidizing effects of ozone are then used for the purpose of purification and disinfection. An
ozone water-producing apparatus can be classified as a pressurized injector, diffused air, Venturi
injector, or other type based on the ozone water-producing method.
A typical ozone water-producing apparatus of the pressurized injector type, as shown in FIG. 1, includes:
- An air pump (10) which draws external air into the apparatus as intake air
- An ozone generator (11) with an ozone-generating unit (12) for converting oxygen contained
in the air supplied from the air pump (10) into ozone
- A mixer (14) for mixing the ozone supplied from the ozone generator (12) with water supplied
from a water source (13)
- A solenoid valve (16) installed in a water supply line (15) to control the flow of water
supplied to the mixer (14) from the water source (13)
The ozone water-producing apparatus is configured so that when the air pump (10) supplies air to
the ozone-generating unit (12) exclusively, the ozone-generating unit (12) converts oxygen in the
air into ozone. Although a portion of the ozone is converted back into oxygen, most of the ozone
is pushed into the mixer (14) which, in turn, mixes the ozone into water supplied from the water
source (13) to produce and discharge ozone water.
In such a pressurized injector type ozone water-producing apparatus, the ozone is drawn into the
mixer (14) by the negative pressure generated when water from the water source (13) passes through
the water supply line (15) while pressure is generated by the air pump (10). Ozone water is produced
at the point where gas and liquid are mixed.
The ozone water-producing apparatus requires various peripherals to optimize the mixing of water and
ozone. Such auxiliary devices include a mixer for mixing ozone and water, an injector for generating
a negative pressure, and a gas-liquid separator for controlling the amount of air introduced into the water.
Examples of techniques for providing an improved ozone water-producing system are described below.
The Korean Utility Model Registration No. 208,109, introduced by the applicant of the present invention,
uses a modified solenoid valve (injector) and a bubble separator installed in an ozone supply line
connected to an inlet of a mixer. In this system, an increase in water pressure permits the inflow
of ozone without the use of an air pump. The discharge of surplus ozone not mixed into the water is
prevented and a reduction in the number of components and miniaturization are achieved because of the
absence of the air pump. Also, various problems associated with re-use of the ozone, including
possible harm to humans and breakage of the peripheral components, are minimized.
Another apparatus for producing ozone water, Korean Utility Model Registration No. 203,244, also introduced
by the applicant of the present invention, uses an integrated application of the solenoid valve and injector
to shorten the flow channel and replace an air pump, enhancing overall performance of the apparatus.
Such conventional arts are directed to a modified structure of a flow channel for mixing artificially
generated ozone and water. However, several important problems remain.
- The use of air containing foreign substances and moisture causes a decrease in the efficiency of ozone production.
- The ozone water outlet frequently becomes blocked and the ozone water flows backwards. As a result, normal discharge of ozone water is prevented; the entire flow channel performance is compromised; and highly skilled maintenance and repair are required.
- The entire apparatus is technically complex and not suitable for homes and public facilities.
