CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This is a continuation of U.S. patent application Ser. No. 09/914,402 which is a 371 of PCT/US97/11261 filed Jun. 27, 1997, which claims benefit of Ser. No. 60/022,015 filed Jun. 27, 1996, all incorporated herein by reference. STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT [0002] Not applicable REFERENCE TO A "MICROFICHE APPENDIX" [0003] Not applicable BACKGROUND OF THE INVENTION [0004] 1. Field of the Invention [0005] This present invention relates to a point of use water purification unit designed to continuously and completely purify water at all points of use such as homes, restaurants, hotels, military, sea and field units as well as desalination of sea water at the point of use. The device will remove all chemicals, all microorganisms and replete the water with essential ground minerals. [0006] 2. General Background of the Invention [0007] Pure water for consumption, use in cooking and to maintain hygiene is a universal need. The purity and safety of water is deteriorating world wide. Tap water is no longer safe in major U.S. and foreign cities. It is contaminated by microbes, chemicals, heavy metals and in many instances ground water and sewage which gets into the distribution systems which are old and dilapidated. Improvement of municipal water treatment systems will be of little benefit. In line filtration and treatment along the distribution system will also be of little benefit because the distribution systems are old, leaky and in some instances are contaminated by lead joints. Pure water for our cities is a big challenge which will not be soon solved. It is therefore imperative that point of use water purification for all of the water used in the home be the immediate solution. [0008] The following U.S. Patents are incorporated herein by reference: BRIEF SUMMARY OF THE INVENTION [0009] Accordingly, it is an object of this invention to provide a device that will accomplish the function of providing at the point of use a water treatment system that can convert any water into microbe free, chemical free, chlorine free, pleasant tasting, soft, mineral repleted water for the whole house, apartment, restaurant or other establishment. [0010] Another object of the invention is to provide a system for water purification in which the feed water is preheated through a heat exchanger which takes energy from the systems refrigeration unit (condenser side) in order to conserve maximum energy. [0011] Another object of this invention is to provide a thin water layer, centrifugal, vacuum chamber for degassing the feed water. [0012] An additional object of this invention is to take advantage of the peculiar and little known physical character of degassed water. Pure water, when free of dissolved gases, may be heated above 100 degrees C. (up to 180 degrees C.) without boiling, but upon further heating, boiling may occur with explosive violence. This steam at (100 degrees C.) occupies a volume 1700 times greater than water at 100 degrees C. [0013] It is a further object of the invention to isolate the degassing chamber by a series of three (3) in line valves. These valves are electronic and controlled by the on board computer controller. [0014] Another object of the invention is to heat the degassed feed water to 260 degrees F. under pressure and then spray it into a heated 350 degrees F. vacuum chamber, where it flash vaporizes in an explosive manner, thereby providing the pressure and vaporization to evacuate the chamber into the condenser. [0015] Another object of the invention is to provide a brine chilled counter current heat exchanger at 20 degrees F. to condense the vaporized pressured steam to chemically and microbiologically pure water at ambient temperature. [0016] An additional object of this invention is to provide a holding tank containing a UV light source to maintain a microbial free condition of the water and providing high water level and lower water level sensors to regulate system operation through the on board microprocessor. [0017] It is a further object of the invention to provide a booster pump which through in line pressure sensors will provide the desired pressure and flow throughout the system. This pressure and flow will be augmented by smaller in line pumps, if necessary. [0018] A further object of the invention is to pass the water of this invention, as it flows from the holding tank, through a colloidal mineral column (to replace trace minerals) and lastly through a carbon column to assure good taste and freshness of the water. [0019] An additional object of the invention is to provide an electronically heated (or other energy source) vegetable oil circulated through a jacket in the preheat heat exchanger and heated vacuum chamber.
