Abstract

Systems and methods are shown for providing hot beverages using a beverage system integrated into a faucet. The faucet-integrated beverage system can include a hot water reservoir mounted under a countertop and fluidly coupled to a cold water supply line. The temperature and fill level in the hot water reservoir can be controlled using control circuitry provided on a circuit board communicatively coupled to the hot water reservoir and one or more sensors. A beverage supply line can extend from the hot water reservoir to a beverage dispensing unit, which can be coupled to the faucet or mounted on the faucet deck. The beverage system can also include an activation button mounted on the faucet or the faucet deck and communicatively coupled to the control board for initiating a brewing process.

First claim

What is claimed is:

1. A faucet-integrated beverage system, comprising:
a faucet comprising a body and a mixing valve fluidly coupled to a hot water supply line and a first branch of a cold water supply line, the mixing valve also being fluidly coupled to a supply tube passing through the faucet body to a dispensing end;
a hot water reservoir configured to fluidly couple to a second branch of the cold water supply line and provide heated water; and
a beverage dispensing unit fluidly coupled to the hot water reservoir via a beverage water supply line, at least a portion of the beverage water supply line passing through the faucet body to deliver heated water from the hot water reservoir to the beverage dispensing unit, the hot water supply line providing heated water to the mixing valve separately from the hot water reservoir.

2. The faucet-integrated beverage system of claim 1 , wherein:
the beverage dispensing unit branches from the body of the faucet.

3. The faucet-integrated beverage system of claim 1 , further comprising an electronic control unit configured to control at least one of:
a water level in the hot water reservoir;
water temperature in the hot water reservoir; and
a supply of water to the beverage dispensing unit.

4. The faucet-integrated beverage system of claim 3 , further comprising:
a supply solenoid valve configured to fluidly couple to the second branch of the cold water supply line and communicatively couple to the electronic control unit, the supply solenoid valve being further configured to occupy open and closed positions such that, when the supply solenoid valve is in open position, water is permitted to flow from the cold water supply line into the hot water reservoir, and when the supply solenoid valve is in closed position, water is prevented from flowing from the cold water supply line into the hot water reservoir.

5. The faucet-integrated beverage system of claim 4 , further comprising:
a water level sensor disposed at least partially within the hot water reservoir and configured to communicatively couple to the electronic control unit, wherein:
the water level sensor is further configured to provide water level signals to the electronic control unit indicative of the water level in the hot water reservoir; and
the electronic control unit is further configured to control the supply solenoid valve based on the water level signals by:
causing the supply solenoid valve to occupy open position when the water level in the hot water reservoir is at or below a lower threshold; and
causing the supply solenoid valve to occupy closed position when the water level is at or above an upper threshold.

6. The faucet-integrated beverage system of claim 5 , comprising:
a dispenser solenoid valve configured to fluidly couple to the beverage supply line and communicatively couple to the electronic control unit, the dispenser solenoid valve being further configured to occupy open and closed positions such that, when the dispenser solenoid valve is in open position, water is permitted to flow from the hot water reservoir to the beverage dispensing unit, and when the dispenser solenoid valve is in closed position, water is prevented from flowing from the hot water reservoir to the beverage dispensing unit.

7. The faucet-integrated beverage system of claim 6 , further comprising:
a switch configured to communicatively couple to the electronic control unit, wherein:
activation of the switch causes transmission of an activation signal to the electronic control unit, the activation signal being operative to instruct the electronic control unit to open both the supply solenoid valve and the dispenser solenoid valve; and
the electronic control unit is further configured to cause both the supply solenoid valve and the dispenser solenoid valve to occupy open positions such that water is permitted to flow from the hot water reservoir into the beverage dispensing unit.

8. The faucet-integrated beverage system of claim 7 , wherein:
the electronic control unit is further configured to cause both the supply solenoid valve and the dispenser solenoid valve to occupy closed positions one of:
after the dispenser solenoid valve has been open for a defined period of time; and
after a defined volume of water has passed through the dispenser solenoid valve.

9. The faucet-integrated beverage system of claim 3 , further comprising:
a heating element configured to communicatively couple to the electronic control unit and heat water in the hot water reservoir.

10. The faucet-integrated beverage system of claim 9 , further comprising:
a temperature probe at least partially disposed in the hot water reservoir and configured to communicatively couple to the electronic control unit, wherein:
the temperature probe provides temperature signals to the electronic control unit indicative of the water temperature in the hot water reservoir; and
the electronic control unit controls the heating element based on the temperature signals by:
causing the heating element to turn on when the water temperature in the hot water reservoir is at or below a lower threshold; and
causing the heating element to turn off when the water temperature is at or above an upper threshold.
