Abstract
A continuous water distillation system has a steam chamber assembly and a condenser assembly for making steam and condensing the steam into purified water. An associated holding tank collects the purified water for dispensing upon user demand. The quantity of purified water is continuously sensed in the holding tank. A controller coordinates the operation of the steam chamber assembly and the purified water delivery mechanism to dispense purified water from the holding tank upon demand and automatically make and replenish the supply of purified water. In one arrangement, a first sensor continuously senses the purity of the water collected in the holding tank, while a second sensor continuously senses the purity of the water entering the steam chamber assembly. In another arrangement, the condenser assembly includes a cooling fan with a replaceable air filter, and the purified water dispenser includes an inline water filter. The controller prompts the user to replace the air and water filter according to different operational criteria.
