U.S. Pat. No. 6,163,893 disclosed a deodorizing toilet seat pad comprising essentially an ozone-generating means, a toilet seat pad, a base plate, a fan and an active carbon container. When practicing, the fan is operated to draw the stench odor from the toilet into the ozone-generating means where odor is deodorized. Then, the discharged gas is further deodorized by active carbon to remove residual stench.
However, such a deodorizing system may have the following disadvantages:
The present inventor has found the drawbacks of the conventional deodorizing toilet and invented the present ozone-deodorizing toilet.
The object of the present invention is to provide an ozone-deodorizing toilet including: an ozone generator provided in a box formed on a rear portion of a toilet seat, a gas outlet formed in a front portion of the box and under the toilet seat, whereby upon seating of a toilet user on the toilet seat and upon actuation of the ozone generator, the ozone as produced from the ozone generator is applied under positive pressure into a bowl chamber as defined among the toilet bowl, the toilet seat and the user's buttocks to allow the ozone to efficiently deodorize and disinfect the stench gas in the bowl chamber of the toilet.
As shown in the drawing figures, the present invention comprises: an ozone generator 1 installed in a box 2 formed on a rear portion of the toilet seat 5, a plurality of air inlet ports 3 formed in a side portion of the box 2 to direct air into the box 2 to be fluidically communicated with the ozone generator 1 for conversion of air into ozone O3, and a gas outlet port 4 formed in a central front portion of the box 2 and formed under the toilet seat 5 for outwardly downwardly discharging ozone O3 as produced from the ozone generator 1 into the toilet bowl Bw.
The toilet seat 5 is pivotally formed on a toilet bowl and formed with an opening 50 to be sealed by a toilet user's buttocks B (
For understanding the operation principles of the ozone generator 1, the circuit diagram as shown in
When the power source P.S. is closed to produce a high tension across the cathode E1 and anode E2 through the high-tension generator H.T., the air in the gap G (for example, 3 mn) between the two electrodes E1, E2 across the high-tension field will be ionized to form an electronic wind and the air is also partially converted into percentage of ozone O3, which is then laden in the electronic wind caused by the ionized air and discharged into a bowl chamber C as defined among the toilet bowl Bw, the toilet seat 5, and the user's buttocks B as shown in
Since ozone O3 is heavier than air, the residual ozone gas, after deodorizing or disinfecting the gas within the bowl chamber C, will be dissolved into water under the water level W to further deodorize or disinfect the waste water in the toilet bowl Bw.
The ozone gas is directed into the bowl chamber C under positive pressure and is, however, confined within the chamber C by the user's buttocks B, the toilet seat 5 and the bowl Bw without serious outward leakage into the environment of a bathroom or rest room.
The air through the gap G in the ozone generator 1 may be converted from an insulator to be a semi-conductor under the high tension field to obtain a percentage of ozone, which may be driven from the first electrode E1 having a plurality of discharge tips D towards the second electrode E2 having a plurality of air vents V formed therein (as shown in
The present invention is superior to the conventional deodorizing toilet with the following advantages:
An automatic electronic system may be provided in the present invention to automatically start the ozone generator in a preset time period so as to emit ozone in a proper time period for satisfactorily deodorization and disinfection in the toilet.
The present invention may be modified without departing from the spirit and scope of the present invention.
