Abstract:
A liquid purifier comprising a housing having a first chamber and a second chamber; divider means separating the first and the second chambers one from the other; the divider means comprising a thermoelectric module having a heatable surface received within the first chamber and a coolable surface received within the second chamber; means for contacting impure liquid feed with the heatable surface within the fist chamber to produce vapor; first transfer means comprising vapor guide means for directing a minor portion of the vapor adjacent to or onto the coolable surface to effect heat transfer to the coolable surface to maintain temperature of the coolable surface at the boiling point of the liquid; condenser means having a second coolable surface for condensing a major portion of the vapor within the second chamber by heat transfer to produce purified liquid; second transfer means for transferring the major portion of the vapor to the condenser means; means for pre-heating the impure liquid feed by the heat transfer with the condenser means; and the thermoelectric module comprises means for receiving an electric current to activate the module to heat the heatable surface and cool tie coolable surface.
