Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
90 words
An oxygen generator, installed in an air conditioner which contains at least a cooling device for cooling at least indoor air, comprising: a reservoir for storing water condensed from air which air is cooled off while passing through said cooling device: an electrolyzer; means for directing water from said reservoir to said electrolyzer; said electrolyzer for electrolyzing water into oxygen and hydrogen; means for directing oxygen from said electrolyzer indoors; and a controller for controlling water supply to said electrolyzer and the electrolysis volume to provide the required indoor oxygen.
Claim 2
Dependent Claim
90 words
An oxygen generator, installed in an air conditioner which contains at least a cooling device for cooling at least indoor air, comprising: a reservoir for storing water condensed from air which air is cooled off while passing through said cooling device: an electrolyzer; means for directing water from said reservoir to said electrolyzer; said electrolyzer for electrolyzing water into oxygen and hydrogen; means for directing oxygen from said electrolyzer indoors; and a controller for controlling water supply to said electrolyzer and the electrolysis volume to provide the required indoor oxygen.
Claim 3
Dependent Claim
31 words
The oxygen generator of claim 1, wherein the electrolysis volume is controlled by said controller based on a value detected by an indoor oxygen content detector comparing with a preset value.
Claim 4
Dependent Claim
57 words
The oxygen generator of claim 1, including means to direct polluted indoor air to the outdoors, wherein, while the oxygen is directed indoors, a suitable amount of polluted indoor air is expelled outdoors through a valve controlled by said controller based on a value detected by an indoor carbon dioxide content detector comparing with a preset value.
Claim 5
Dependent Claim
56 words
The oxygen generator of claim 1, including means to vaporize hydrogen, and means to direct hydrogen vapor outdoors, wherein the hydrogen obtained from electrolysis is converted to vapor and selectively conveyed indoors and outdoors through a valve controlled by said controller based on a value detected by an indoor humidity detector comparing with a preset value.
Claim 6
Dependent Claim
27 words
The oxygen generator of claim 2, wherein the electrolysis volume is controlled by said controller further based on a value detected by an outdoor oxygen content detector.
Claim 7
Dependent Claim
30 words
The oxygen generator of claim 1, wherein the electrolysis volume is controlled by said controller based on the number of persons in the room which is detected by a detector.
Claim 8
Dependent Claim
30 words
The oxygen generator of claim 6, wherein, while the oxygen is sent indoors, a suitable amount of polluted indoor air is expelled out through a valve controlled by said controller.
