  "abstract": "A water supply system includes a main water tank that is configured to store water and includes a heater to heat the stored water to close to but below a boiling temperature thereof, to provide main heated water. A dispenser water tank receives a portion of the main heated water, and is free of any heating elements to add heat to the water stored therein, and providing dispensable heated water. A water mixer includes a first pipe for receiving the dispensable heated water from the dispenser tank and a second pipe for receiving utility water from a faucet that supplies utility-provided water, with a mixing chamber from which the waters from the first pipe and the second pipe are dispensed and/or in which these waters are admixed.",
  "claims": [
    "1. A hot water supply system that is compliant with Jewish Sabbath strictures, the system including: a main water tank that is configured to store water and includes a heater to heat the stored water to close to but below a boiling temperature thereof, to provide main heated water; a dispenser water tank configured to receive a portion of the main heated water, the dispenser water tank being free of any heating elements capable of adding heat to the water stored therein, and providing dispensable heated water; a water mixer including a first pipe for receiving the dispensable heated water from the dispenser tank, while the dispenser water tank is physically separated from the main water tank, and a second pipe having a first end that is connectible to the water mixer and a second end that is configured to be attached to a faucet that supplies utility-provided water, and the water mixer including a mixing chamber from which the waters from the first pipe and the second pipe are dispensed for being used by a user.",
    "2. The supply system of claim 1, in which the main heater has a Sabbath mode function that turns on the heater on a Sabbath intermittently, without receiving any input from any temperature sensor.",
    "3. The supply system of claim 1, wherein the main tank includes a hand-operated pump for pumping water from the main tank into the dispenser tank.",
    "4. The supply system of claim 3, wherein the hand-operated pump includes a rotatable handle to effect pumping of the main heated water.",
    "5. The supply system of claim 2, wherein the main tank includes wheels to enable it to roll over a floor surface, and wherein the main tank has a water storage capacity in the range from 5 to 30 gallons.",
    "6. The supply system of claim 2, the main tank including a water supply pipe that has a distal end with an enlarged opening that enables the water supply pipe to be fitted on a water dispensing end of a home utility water faucet and a tightening device that seals a connection between the water supply pipe and the faucet against water leakage.",
    "7. The supply system of claim 1, the main tank including a water level gauge.",
    "8. The supply system of claim 1, the dispenser tank including legs to raise the height of the dispenser tank above the counter surface of a kitchen adjacent the faucet.",
    "9. The supply system of claim 1, the dispenser tank being associated with platform that is configured to elevate the dispenser tank above a kitchen counter surface.",
    "10. The supply system of claim 1, including a canister of pressurized air that is air coupled to an interior of the dispenser tank to pressurize the dispensable heated water, to increase its flow rate from the dispenser tank.",
    "11. The supply system of claim 1, the dispenser tank including a water flow valve that is configured to control a flow rate of the dispenser heated water into the water mixer.",
    "12. The supply system of claim 1, the dispenser tank including a normally covered access opening that can be uncovered to allow reaching into the dispenser tank to allow interior surfaces inside the dispenser tank to be wiped dry between water filling thereof on the Sabbath.",
    "13. The supply system of claim 1, including an articulation arm that is configured to be attached at one end thereof to a comparatively immovable object and at a second end thereof to the water mixer, and is configured to hold the water mixer in space suspended over a draining sink.",
    "14. The supply system of claim 13, wherein the mixing chamber of the water mixer has an aerator at a water dispensing end of the water mixer.",
    "15. The supply system of claim 13, wherein the water mixer dispenses the faucet water from the second pipe into the mixing chamber at location below a point of entry of the dispenser heated water into the mixing chamber.",
    "16. The supply system of claim 13, the water mixer including a plurality of water nozzles for injecting the faucet water into the mixing chamber.",
    "17. The supply system of claim 13, wherein the dispenser tank is cylindrically shaped and configured to be hung from a hook located above a draining sink.",
    "18. The supply system of claim 1, in which the mixing chamber is configured so that the waters from the first and second pipes are admixed in the mixing chamber.",
    "19. A hot water supply system that is compliant with Jewish Sabbath strictures, the system including: a stand-alone dispenser water tank configured to hold heated water, the dispenser water tank being free of any heating elements capable of adding heat to the water stored therein, and providing dispensable heated water; and a water mixer including a first pipe for receiving the dispensable heated water from the stand-alone dispenser tank and a second pipe having a first end that is connectible to the water mixer and a second end that is configured to be attached to a faucet for receiving utility-provided water, and the water mixer including a mixing chamber in which the waters from the first pipe and the second pipe are admixed.",
    "20. The hot water supply system of claim 19, wherein the water mixer is integrated and formed to be a part of the dispenser tank."

  "description_excerpt": "The present invention is generally directed to water dispensing apparatus and, more particularly, to a system and method that facilitates providing heated water for use on the Jewish Sabbath and Holidays, when heating and cooking water is severely restricted by stringent religious laws.\n\nThe general subject to which the present invention is directed has been discussed in many prior patents and patent applications including in US patent application publication number US 2007/0261561, the contents of which are incorporated by reference herein. According to the practice of orthodox Jews, one may not perform an act of work on the Sabbath. For example, one may not turn on or off the lights on a Sabbath. However, if the light was turned on before the entry of the Sabbath, one may keep the light on and use it the entire Sabbath, provided one does not turn it off before the Sabbath is over. Similarly, one may use hot water if the water heater was energized prior to the entry of the Sabbath, and the water heater is not turned on or off during the Sabbath in response to actions taken by the user of water. As can be understood, due to the operation of conventional water dispensers, i.e., the refilling and re-heating as hot water is dispensed, Sabbath observers cannot use such dispensers during the Sabbath.\n\nOne Sabbath requirement is that refilling and reheating of the hot water reservoir tank is not permitted.",
