Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
160 words
An ozone drinking water cooling and purification apparatus constructed as a pre-manufactured household appliance and comprising: a supply system including a tank for storing water, cooling means for cooling said water within said tank, a measuring device for monitoring the redox potential of said water at a preselected location of said supply system, an ozone generator, an ozone injector coupled with said ozone generator to inject ozone into said water at another preselected location of said supply system for purification of said water and for increasing the redox potential thereof up to a preselected drinking water redox potential whenever said measuring device signals that the water redox potential is below said preselected water redox potential, faucet means for taking water from said tank, and automatic preventing means connected to said redox potential measuring device and controlled therby for preventing water not having at least said preselected drinking water redox potential from being taken from said tank via said faucet means.
Claim 2
Dependent Claim
160 words
An ozone drinking water cooling and purification apparatus constructed as a pre-manufactured household appliance and comprising: a supply system including a tank for storing water, cooling means for cooling said water within said tank, a measuring device for monitoring the redox potential of said water at a preselected location of said supply system, an ozone generator, an ozone injector coupled with said ozone generator to inject ozone into said water at another preselected location of said supply system for purification of said water and for increasing the redox potential thereof up to a preselected drinking water redox potential whenever said measuring device signals that the water redox potential is below said preselected water redox potential, faucet means for taking water from said tank, and automatic preventing means connected to said redox potential measuring device and controlled therby for preventing water not having at least said preselected drinking water redox potential from being taken from said tank via said faucet means.
Claim 3
Dependent Claim
33 words
