ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a radical generating system, and more particularly, to radical generating system having a bubble generating means, an ozone generating means, and a radical changing means all formed integrally.
2. Prior Art
Most clothes washing machines wash the laundry by using the mechanical force of a pulsator and the surface active force of a chemical detergent. Accordingly, in order to improve the washing efficiency, many clothes washing machine makers have utilized various methods including: improving the pulsator's ability to agitate the laundry, extending the operation time of the motor for water flow time, and improving the quality and/or increasing the quantity of detergent used in the washing machine. However, there are limits to improvements in the washing efficiency by the aforementioned methods for the following reasons. The methods utilizing increased mechanical force to improve the washing efficiency may damage the laundry or decrease efficiency of the clothes washing machine.
In the methods utilizing increased amounts of detergent, a relatively large amount of the detergent which does not react with the laundry is then discharged where it can later cause environmental pollution, and also the remaining detergent sticks to the laundry and thus the laundry is not effectively cleaned.
U.S. Pat. No. 5,653,129, (issued to Byung-Kew Jang on Aug. 5, 1997) discloses a bubble automatic washing machine, which has a bubble generating means and an ozone generating means connected to each other in parallel.
FIG. 1
shows a conventional bubble automatic washing machine
100
with a bubble generating means and an ozone generating means connected to each other in parallel, described in the U.S. Pat. No. 5,653,129.
The washing machine
100
includes a housing
102
and a stationary washer tub
104
fixedly mounted within housing
102
for containing a level of washing fluid therein. Pulsator
106
is rotatable in a forward or reverse direction to create a vortex flow within rotatable tub
112
.
The top of washing machine
100
is provided with a door
108
for loading and unloading the laundry articles. Bubble generating means
110
is mounted on the inner surface of door
108
to extend toward rotatable tub
112
. Bubble generating means
110
is shown in
FIG. 2
in detail. An air pump
116
is communicated with bubble generating means
110
through an air conduit
114
. In the drawings, air pump
116
is installed at the bottom plate of washing machine
100
but may be installed at any other suitable place.
Bubble generating means
110
includes a telescopic pipe
202
which is movable upward and downward, and driver
204
for actuating telescopic pipe
202
. Though
3
-stage telescopic pipe
202
is shown in the drawings, the number of stages is not specially limited as long as the washing machine operates smoothly.
Telescopic pipe
202
is fixed to a casing
218
of driver
204
coaxially with rotatable tub
124
. Casing
218
is fixed to the inner surface of door
108
and a DC motor
206
is installed to casing
218
. A driving shaft
208
of DC motor
206
is operatively connected to a first pulley
210
which is operatively connected to a second pulley
214
through a belt
212
.
Second pulley
214
has a groove for belt
212
and gear teeth formed separately, and a flexible plastic string
216
is wound on the gear teeth. A train of teeth is formed on flexible plastic string
216
to mesh with the gear teeth. Flexible plastic string
216
has a suitable flexibility for being forced to expand and withdraw telescopic pipe
202
.
Flexible plastic string
216
extends within, via a hole
219
formed to casing
218
, an inner telescopic pipe
220
which is coaxially installed inside the inner telescopic pipe
202
and has the top end fixed to casing
218
. The end of flexible plastic string
216
is fixed to the lower end of inner telescopic pipe
220
which is fixed to the lower end of telescopic pipe
202
.
The lowest stage of telescopic pipe
202
is provided with a plurality of spurt holes
222
to create air bubbles. Air conduit
114
extends through casing
218
and communicates with inside of telescopic pipe
202
. A space between telescopic pipe
202
and inner telescopic pipe
220
serves as an air passage and the air flowing out of air conduit
114
blows into rotatable tub
112
, sequentially passing through the space and spurt holes
222
.
An ozone generating means
118
may be further installed between air pump
116
and driver
204
in order to kill bacteria inhabiting the laundry articles. As a result, ozone is contained in air bubbles blowing into rotatable tub
124
to remove bacteria from the laundry articles.
Moreover, a heater
120
may be installed between ozone generating means
118
and driver
204
in order to create a hot air stream for drying the laundry articles. The air stream generated from air pump
116
flows through air conduit
114
to heater
120
to heat up and is transmitted to the laundry articles within rotatable tub
112
.
However, a conventional bubble automatic washing machine with the bubble generating means and the ozone generating means connected to each other in paralled has drawbacks,e.g., installation space is occupies a large area and oxygen(O
2
) through the bubble generating means has low degree of generating efficiency of an ozone. In order to get force of washing and cleaning for proper washing is a large amount of ozone is indispensable as well. As a result, induced ozone has the disadvantage of inflict bodily harm due to the high concentration and bad odor of ozone itself.
SUMMARY OF THE INVENTION
Therefore, it is an object of the present invention, for the purpose of solving the above mentioned problems, to provide a radical generating system which integrates a bubble generating means, an ozone generating means, and a radical changing means.
In order to attain the object, according to the present invention, there is provided a radical generating system comprising a housing with a gas mixing chamber disposed therein; a bubble generating means disposed in the housing for pumping air into the gas mixing chamber in order to develop compressed air in the gas mixing chamber; an ozone generating means disposed in the gas mixing chamber for generating ozone from the compressed air; and a radical changing means disposed in the housing and in communication with the gas mixing chamber for changing the ozone received from the gas mixing chamber into active oxygen. The radical changing means includes a catalyst chamber having a hollow, a first side wall having an inlet for allowing the ozone to be introduced from the gas mixing chamber to the catalyst chamber, and a second side wall having an outlet for the active oxygen. An active oxygen generation catalyst is stored in the hollow for catalyzing the change of the ozone into the active oxygen.
Other objects and further features of the present invention will become apparent from the detailed description when read in conjunction with the attached drawings.
