Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 269 words
An appliance assembly for use in a room which comprises: an air processing structure for air cleaning and humidifying the room, said air processing structure including a water tank, a filter chamber disposed in said water tank, an electrical turbo fan disposed within said filter chamber, a motor mount housing disposed within said water containing member, a motor rotor supported by said housing operatively associated with said turbo fan, a filter cover containing six filter stages, a cover grille as an air intake disposed on said filter cover for receiving unfiltered air, and a plurality of apertures for exhausting cleaned and humidified air to the atmosphere, wherein said six filter stages include a first stage containing impingement fiber for filtering large size airborne particles, a second stage containing a coated filter for absorbing the particles, a third stage containing an activated charcoal filter for absorbing odors, a fourth stage containing a woven fabric filter for filtering contaminants, a fifth stage containing a coated filter for electrostatically absorbing the particles, and a sixth stage containing a filter for eliminating submicron airborne pollutants; and an electrochemical reactor operatively connected to said air processing structure for activating a gas alarm and supplying oxygen to the room, said electrochemical reactor being detachable from said air processing structure, and said electrochemical reactor including an electrolysis system for supplying oxygen, an oxygen controlling system for controlling the supply of oxygen at a predetermined percentage in the room and a gas alarm system for monitoring carbon monoxide, wherein the assembly is constructed so as to be used as an air cleaner, humidifier, gas alarm, and oxygen-supplier.
Claim 2
Dependent Claim 269 words
An appliance assembly for use in a room which comprises: an air processing structure for air cleaning and humidifying the room, said air processing structure including a water tank, a filter chamber disposed in said water tank, an electrical turbo fan disposed within said filter chamber, a motor mount housing disposed within said water containing member, a motor rotor supported by said housing operatively associated with said turbo fan, a filter cover containing six filter stages, a cover grille as an air intake disposed on said filter cover for receiving unfiltered air, and a plurality of apertures for exhausting cleaned and humidified air to the atmosphere, wherein said six filter stages include a first stage containing impingement fiber for filtering large size airborne particles, a second stage containing a coated filter for absorbing the particles, a third stage containing an activated charcoal filter for absorbing odors, a fourth stage containing a woven fabric filter for filtering contaminants, a fifth stage containing a coated filter for electrostatically absorbing the particles, and a sixth stage containing a filter for eliminating submicron airborne pollutants; and an electrochemical reactor operatively connected to said air processing structure for activating a gas alarm and supplying oxygen to the room, said electrochemical reactor being detachable from said air processing structure, and said electrochemical reactor including an electrolysis system for supplying oxygen, an oxygen controlling system for controlling the supply of oxygen at a predetermined percentage in the room and a gas alarm system for monitoring carbon monoxide, wherein the assembly is constructed so as to be used as an air cleaner, humidifier, gas alarm, and oxygen-supplier.
Claim 3
Dependent Claim 47 words
The assembly of claim 1, wherein the gas alarm system includes an on/off switch operatively associated therewith, a buzzer operatively connected to said switch, cells, plurality of resisters, and diodes operatively associated with said buzzer for activating said buzzer upon detecting the presence of said carbon monoxide.
Claim 4
Dependent Claim 44 words
The assembly of claim 1, wherein the electrolysis system contains a first ceramic conductive path member which includes a cathode, a second ceramic conductive path member which includes an anode, and a diaphragm operatively disposed between said first and second ceramic conductive path members.
Claim 5
Dependent Claim 44 words
The assembly of claim 3, wherein the oxygen controlling system includes an on/off switch operatively associated therewith, and an oxygen percentage meter operatively connected to a sample measuring cell, a sample referencing cell, and a pressure compensating cells for measuring oxygen in the room.
Claim 6
Dependent Claim 27 words
The assembly of claim 3, wherein the cathode disposed in the ceramic conductive path member is operatively connected to a cathode lead through a cathode leader cable.
Claim 7
Dependent Claim 27 words
The assembly of claim 5, wherein the anode disposed in the ceramic conductive path member is operatively connected to an anode lead through an anode leader cable.
