Abstract
A dental water sterilization unit having a heat treater which raises the temperature of domestic water supply to the sterilization unit sufficiently to sterilize and deoxygenate the water and then cools the water to a suitable temperature for comfort of the dental patient. The unit may have a water chiller or heat exchanger to lower the temperature. The unit may also have a porous packing in the heat treater to enter mixed steam and water to facilitate the sterilization and deoxygenation process.
Claims24
A dental water sterilization system comprising:
- (a) an inlet passageway adapted to be placed in selective fluid communication with a source of incoming domestic water;
- (b) a heat treater having:
- a treater inlet in selective fluid communication with the inlet passageway and adapted to receive domestic water from the inlet passageway,
- a treater outlet,
- a treating zone between the heater inlet and treater outlet, and
- a heater in the treating zone, which heats the received domestic water in the treating zone sufficiently to deoxygenate and sterilize the received water during passage of the water through the treating zone, said heater producing steam that passes through the received domestic water extracting dissolved oxygen, to produce a supply of heated deoxygenated sterilized water at the treater outlet,
- a steam or oxygen relief passage;
- and
- (c) an outlet passageway in selective fluid communication with the treater outlet, cooling the received portion of a selected temperature, thereby producing sterilized deoxygenated water at a temperature suitable for the desired use in a dental apparatus.

A dental water sterilization system comprising:
- an inlet passageway which is placed in selective communication with a source incoming domestic water;
- a heat treater in selective fluid communication with the supply passageway and adapted receive the incoming water from the supply passageway and capable of deoxygenating and sterilizing the incoming water thus received by application of heat to the water during passage through a treating zone in the treater and thereby generating an output supply of heated sterilized deoxidized water;
- a cooling device in fluid communication with the heat treater to receive and cool the output supply of heated sterilized deoxidized water;
- and
- an outlet passageway to supply the cooled sterilized deoxidized water from the chiller to a dental apparatus.
