Definitions

  • the present invention relates to an ozone-deodorizing toilet.
  • U.S. patent 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.
  • 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.
  • the present inventor has found the drawbacks of the conventional deodorizing toilet and invented the present ozone-deodorizing toilet.
  • a deodorizing toilet including: an ozone generator provided in a box (chamber) formed e.g. at 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.
  • 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 O 3 , 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 O 3 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 (Fig. 1) or to be closed by a toilet cover 6 as shown in dotted line of Fig. 1.
  • the air in the gap G (for example, 3 mm) between the two electrodes E 1 , E 2 across the high-tension field will be ionized to form an electronic wind and the air is also partially converted into percentage of ozone O 3 , 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 Fig. 1 to deodorize or disinfect the stench gas in the toilet bowl Bw.
  • the cathode E1 may be -4000 volts, while anode E 2 may be O volt (or other positive volts).
  • a plurality of discharge tips D are juxtapositionally formed on the cathode E 1 , each discharge tip D aiming at (or aligned with) each air vent V formed in the anode E 2 .
  • the air in the gap G will be ionized to form an electronic wind to flow from E 1 to E 2 and the air is also partially converted into ozone O 3 to be "blown" outwardly though the port 4 driven by the electronic wind (Fig. 3).
  • 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 E 1 having a plurality of discharge tips D towards the second electrode E 2 having a plurality of air vents V formed therein (as shown in Fig. 3).
  • the ozone-containing gas may be driven through the holes H and then discharged into the bowl chamber C in the toilet bowl Bw for deodorization and disinfection within the toilet.
  • 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.
