Abstract

A portable liquid heating and dispensing system is provided. A preferred embodiment includes a self-contained dispensing unit and a receiver. The dispensing unit may include a container portion, a dispensing portion, and an electric heat generating portion. The container portion has a main reservoir for holding a supply of the liquid to be dispensed. The dispensing portion has a down tube, a manually operated pump mechanism connected to the down-tube, and an outlet spout connected to the pump mechanism. The pump mechanism has a liquid reservoir. Liquid is drawn through the down tube and into the liquid reservoir and out of the outlet spout. The heat generating portion is positioned at the liquid reservoir, so that liquid pumped out of the main reservoir is heated before being pumped out of the spout. The receiver accepts and provides power to the self-contained dispensing unit.

Claims

1. A portable liquid heating system for heating and dispensing a liquid, the system comprising:

a self-contained dispensing unit comprising;

a container portion with a main liquid reservoir for holding a supply of the liquid to be dispensed and a neck portion with an opening;

a dispensing portion having a down tube with a flow conduit, a manually operated pump mechanism connected to the down tube, and an outlet spout connected to the pump mechanism, the pump mechanism having a pump mechanism liquid reservoir, whereby liquid in the main reservoir of the container portion is received by the down tube and pumped into the pump mechanism liquid reservoir and out of the outlet spout; and

an electric heat generating portion positioned at the dispensing portion, whereby liquid pumped out of the main reservoir is heated before being dispensed through the outlet spout;

a receiver for accepting the self-contained dispensing unit, the receiver providing a power source removably connectable to the electric heat generating portion; and

wherein the receiver further provides presence sensing means, whereby when the self-contained dispense unit is not positioned in the receiver, power to the coil in the receiver is at least reduced.

2. The portable liquid heating system of claim 1, wherein the receiver and the electric heat generating portion each comprise at least one metallic contact, said metallic contacts conducting electricity from the receiver to the electric heat generating portion.

3. The portable liquid heating system of claim 1, wherein the receiver and the electric heat generating portion comprise a pair of power transfer coils, one of said power transfer coils located in the receiver and one located in the electric heat generating portion.

4. The portable liquid heating system of claim 1, wherein the pump mechanism is comprised of a cylinder and a piston, and wherein said cylinder and piston define the pump mechanism liquid reservoir, and wherein the heat generating element contacts the liquid in said pump mechanism liquid reservoir.

5. The portable liquid heating system of claim 1, wherein the receiver is configured as a stand that supports the self-contained dispensing unit.

6. The portable liquid heating system of claim 1, further comprising a temperature control for reducing the power to the heating portion when a predetermined temperature is reached by liquid in the dispensing portion.

7. The portable liquid heating system of claim 1, wherein the heat generating portion is positioned at said pump mechanism reservoir.

8. The portable liquid heating system of claim 7, wherein the pump mechanism comprises a cylinder and a manually operated piston, said piston and cylinder defining the liquid reservoir, and wherein the heat generating portion is positioned in said reservoir.

9. The portable liquid heating system of claim 1, wherein the heat generating portion removably couples with the exterior of the receiver.

10. A portable liquid heating system for heating and dispensing a liquid, the system comprising:

a self-contained dispensing unit comprising;

a container portion with a main liquid reservoir for holding a supply of the liquid to be dispensed and a neck portion with an opening;

a dispensing portion having a down tube with a flow conduit, a manually operated pump mechanism connected to the down tube, and an outlet spout connected to the pump mechanism, the pump mechanism having a pump mechanism liquid reservoir, whereby liquid in the main reservoir of the container portion is received by the down tube and pumped into the pump mechanism liquid reservoir and out of the outlet spout; and

an electric heat generating portion positioned at the dispensing portion, whereby liquid pumped out of the main reservoir is heated before being dispensed through the outlet spout;

a receiver for accepting the self-contained dispensing unit, the receiver providing a power source removably connectable to the electric heat generating portion; and

a timer to discontinue providing power to the self-contained dispensing unit after said unit has not been removed from the receiver for a predetermined period of time.

11. A portable liquid heating system for heating and dispensing a liquid, the system comprising:

a self-contained dispensing unit comprising;

a container portion with a main liquid reservoir for holding a supply of the liquid to be dispensed and a neck portion with an opening;

a dispensing portion having a down tube with a flow conduit, a manually operated pump mechanism connected to the down tube, and an outlet spout connected to the pump mechanism, the pump mechanism having a pump mechanism liquid reservoir, whereby liquid in the main reservoir of the container portion is received by the down tube and pumped into the pump mechanism liquid reservoir and out of the outlet spout; and

an electric heat generating portion positioned at the dispensing portion, whereby liquid pumped out of the main reservoir is heated before being dispensed through the outlet spout;

a receiver for accepting the self-contained dispensing unit, the receiver providing a power source removably connectable to the electric heat generating portion; and

a timer to discontinue providing power to the self-contained dispensing unit after the system has not been manually contacted for a predetermined period of time.
