Abstract

An automatic clothes washing machine includes an outer housing, a tub mounted in the housing, and a perforated basket mounted in the tub. An ozone generator generates ozone which is conducted to water in the tub for sterilizing, bleaching and deodorizing clothes being washed. The ozone is conducted through a double-wall pipe to a perforated ozone distributor disposed between the tub and basket. The ozone generator comprises a flexible tube which is intermittently compressed by an electromagnetically controlled actuator for directing air toward an ozone-producing electrode.

Claims

1. An automatic clothes washing machine comprising:

a main housing;

a clothes container assembly disposed in said main housing and including a motor-driven agitator;

an ozone generating for generating ozone;

an ozone distributor disposed in said clothes container assembly for distributing ozone into wash water in said clothes container assembly; and

a conduit for conducting ozone from said ozone generating to said ozone distributor, said conduit including a connection pipe having a double wall structure comprised of inner and outer pipe sections, the inner pipe section conducting the ozone.

2. An automatic clothes washing machine according to claim 1, wherein said clothes container assembly comprises a tub and a perforated basket disposed in said tub, said ozone distributor disposed between said tub and said basket.

3. An automatic clothes washing machine according to claim 2, wherein said conduit means comprises a hollow connection member mounted on a wall of said tub, a connection pipe extending from said ozone generator to said connection member, and a connection tube extending from said connection member to said ozone distributor.

4. An automatic clothes washing machine according to claim 1, wherein said outer pipe section is corrugated.

5. An automatic clothes washing machine according to claim 1, wherein said ozone-generating means comprises an electrode for producing ozone from air supplied thereto, a flexible air supply tube having an inlet end and a discharge end directed toward said electrode, a movable member movable to a first position compressing said air supply tube in a manner discharging air through said discharge end, and to a second position for releasing the compression of said air supply tube to enable air to enter said air supply tube through said inlet end, and actuating means for intermittently moving said movable member between said first and second positions.

6. An automatic clothes washing machine according to claim 1, wherein said ozone distributor comprises a casing having a plurality of perforations formed in a wall thereof.

7. An automatic clothes washing machine according to claim 1, wherein said ozone distributor constitutes a gas distributor from which only gas is discharged.

8. An ozone generator comprising:

an electrode for producing ozone from air supplied thereto;

a flexible air supply tube having an inlet end and

a discharge end directed toward said electrode;

a movable member movable to;

a first position compressing said air supply tube in a manner discharging air through said discharge end, and

a second position for releasing the compression of said air supply tube to enable air to enter said air supply tube through said inlet end; and

actuating means for intermittently moving said movable member between said first and second positions.

9. An ozone generator according to claim 8, wherein said actuating means comprises a first magnet mounted on said movable member for movement therewith, and a stationary second magnet disposed adjacent to said first magnet, one of said magnets comprising an electromagnet, and the other magnet comprising a permanent magnet, said magnets arranged to produce movement of said movable member between said first and second positions.

10. An ozone generator according to claim 9, wherein said first magnet constitutes said permanent magnet, and said second magnet constitutes said electromagnet.

11. An automatic clothes washing machine comprising:

a main housing;

a clothes container assembly disposed in said main housing and including a motor-driven agitator;

an ozone generator for generating ozone;

an ozone distributor disposed in said clothes container assembly for distributing ozone into wash water in said clothes container assembly; and

conduit means for conducting ozone from said ozone generator to said ozone distributor;

said ozone generator comprising an electrode for producing ozone from air supplied thereto, a flexible air supply tube having an inlet end and a discharge end directed towards said electrode, a movable member movable to a first position compressing said air supply tube in a manner discharging air through said discharge end, and to a second position for releasing the compression of said air supply tube to enable air to enter said air supply tube through said inlet end, and actuating means for intermittently moving said movable member between said first and second positions.

12. An automatic clothes washing machine according to claim 11, herein said actuating means comprises a first magnet mounted on said movable member for movement therewith, and a stationary second magnet disposed adjacent to said first magnet, one of said magnets comprising an electromagnet, and the other magnet comprising a permanent magnet, said magnets arranged to produce movement of said movable member between said first and second positions.

13. An automatic clothes washing machine according to claim 12, wherein said first magnet constitutes said permanent magnet, and said second magnet constitutes said electromagnet.

14. An automatic clothes washing machine according to claim 12, wherein said air supply tube includes a projection extending from a side thereof intermediate said inlet and discharge ends, said projection bearing against said movable member.

15. An automatic clothes washing machine comprising:

a main housing;

a clothes container assembly disposed in said main housing and comprising a tub, a perforated basket disposed in said tub, and a motor-driven agitator disposed in said basket;

an ozone-generator for generating ozone;

an ozone distributor disposed in said clothes container assembly between said tub and said basket for distributing ozone into wash water in said clothes container assembly; and

a conduit for conducting ozone from said ozone-generator to said ozone distributor.

16. An automatic clothes washing machine according to claim 15, wherein said ozone distributor comprises a casing having a plurality of perforations formed in a wall thereof.

17. An automatic clothes washing machine according to claim 15, wherein said ozone distributor constitutes a gas distributor from which only gas is discharged.
