Abstract
An apparatus and a method for cleaning a device using ozonated water.
Claims2
An apparatus for cleaning, comprising:
- a water inlet;
- a water outlet;
- a tank for receiving water from said water inlet;
- an ozone generator;
- a first pump in liquid communication with said tank and with said ozone generator, for taking water from said tank, pumping the water past the ozone generator to add ozone to the water, and pumping the ozonated water back into said tank;
- a second pump having an inlet side in liquid communication with said tank and an outlet side in liquid communication with said water outlet, for pumping ozonated water from the tank to the water outlet;
- a Venturi tube associated with said ozone generator such that water passing through said Venturi tube creates a suction which draws ozone into the water;
- and
- a switch which turns the second pump on and off in response to sensing a pressure drop caused by water flowing through the Venturi tube.

- and
- a bypass valve in liquid communication with said tank, with the outlet side of said second pump, and with the water outlet, wherein, when said bypass valve opens, it allows part of the water leaving the second pump to go back to the tank, thereby reducing pressure at the water outlet.
