Abstract

A warmer, for a baby bottle, includes a warming chamber configured to hold the bottle and to place water received in the chamber in contact with the bottle; a heater, in thermal communication with the water, that heats the water to a temperature below its boiling point; and a water disposal system that automatically causes displacement of water relative to the bottle so as to substantially remove water from contacting the bottle, after the bottle has been warmed by the water. Other embodiments of the warmer are provided, along with related methods.

Claims

1. A warmer, for a baby bottle, comprising:

a warming chamber configured to hold the bottle and to hold water received in the warming chamber so as to form a water bath in contact with the bottle;

a heater, in thermal communication with the water, configured to heat the water to a temperature below its boiling point; and

a water disposal system that automatically causes displacement of the water relative to the bottle, wherein the water disposal system includes;

a reservoir configured to store the water; and

a pump disposed within the reservoir, in fluid communication with the warming chamber, and configured to move the water from the reservoir to the warming chamber, wherein the water disposal system is configured so that when the pump is turned off, the water substantially drains from the warming chamber to the reservoir, so as to substantially remove the water from contacting the bottle, after the bottle has been warmed by the water.

2. A warmer according to claim 1, wherein the pump is configured to cause circulation of the water around the bottle in the warming chamber.

3. A warmer according to claim 1, further comprising:

an ultraviolet light source in communication with the water, that sterilizes the water.

4. A warmer according to claim 1, further comprising:

a timer, coupled to the heater and a power input, so as to terminate power to the heater after a predetermined amount of time.

5. A warmer according to claim 1, further comprising:

at least one thermostat, electrically coupled to the heater and a power input, that limits the temperature to which the water is heated.

6. A warmer according to claim 1, wherein the pump is configured so that after the pump has been turned off, water flows from the chamber, through the pump, to the reservoir.

7. A warmer according to claim 1, wherein the water disposal system further comprises:

a drain hole system in the warming chamber through which water drains at a drainage rate to the reservoir,

wherein the pump is configured to pump the water from the reservoir to the warming chamber at a rate faster than the drainage rate.

8. A warmer according to claim 7, wherein the drain hole system includes:

at least one hole near the bottom of the warming chamber, and

an overflow drain at a higher level in the warming chamber, the overflow drain configured to allow the water to flow out of the warming chamber into the reservoir.

9. A warmer according to claim 1, wherein the water disposal system comprises:

a valve configured to cause flow of water out of the warming chamber after the bottle has been warmed by the water.

10. A warmer according to claim 1, wherein the warming chamber includes an overflow drain configured to allow the water to drain from the warming chamber into the reservoir when a water level of the water bath reaches a certain height.

11. A warmer according to claim 1, wherein the pump is configured to maintain the water bath at a substantially constant water level during an active cycle.

12. A warmer, for a baby bottle, comprising:

a warming chamber configured to hold the bottle and to hold heated water received in the warming chamber so as to form a water bath in contact with the bottle; and

a water disposal system that automatically causes displacement of the water relative to the bottle, wherein the water disposal system includes;

a reservoir configured to store the water; and

a pump disposed within the reservoir, in fluid communication with the warming chamber, and configured to move the water from the reservoir to the warming chamber, wherein the water disposal system is configured so that when the pump is turned off, the water substantially drains from the warming chamber to the reservoir, so as to substantially remove the water from contacting the bottle, after the bottle has been warmed by the water.

13. A warmer according to claim 12, wherein the warming chamber includes an overflow drain configured to allow the water to drain from the warming chamber into the reservoir when a water level of the water bath reaches a certain height.

14. A warmer according to claim 12, wherein the pump is configured to maintain the water bath at a substantially constant water level during an active cycle.

15. A warmer according to claim 12, wherein the water disposal system further comprises:

a drain hole system in the warming chamber through which water drains at a drainage rate to the reservoir, wherein the pump is configured to pump the water from the reservoir to the warming chamber at a rate faster than the drainage rate.

16. A warmer according to claim 15, wherein the drain hole system includes:

at least one hole near the bottom of the warming chamber, and

an overflow drain at a higher level in the warming chamber, the overflow drain configured to allow the water to flow out of the warming chamber into the reservoir when a water level of the water bath reaches a certain height.

17. A method of warming a baby bottle, the baby bottle disposed in a warming chamber configured to hold the bottle and to hold water received in the warming chamber so as to form a water bath in contact with the bottle, the method comprising:

heating water in communication with the warming chamber to a temperature below the water'"'"'s boiling point;

circulating the water around the bottle in the warming chamber; and

operating a water disposal system configured to automatically substantially drain the water bath and remove the water from contacting the bottle after the bottle has been warmed, the water disposal system including;

a reservoir configured to store the water, and

a pump disposed within the reservoir, in fluid communication with the warming chamber, and configured to move the water from the reservoir to the warming chamber, wherein the water disposal system is configured so that when the pump is turned off, the water substantially drains from the warming chamber to the reservoir.

18. A method according to claim 17, further comprising:

draining water from the warming chamber into the reservoir at a drainage rate; and

pumping water from the reservoir to the warming chamber at a rate faster than the drainage rate, until the water in the warming chamber has reached a desired level, so that, when the pump is turned off, the water substantially drains from the warming chamber to the reservoir, thus substantially removing the water from contacting the bottle.

19. A method according to claim 17, further comprising:

draining water from the warming chamber into the reservoir at a drainage rate; and

pumping water from the reservoir to the warming chamber at a rate substantially equal to the drainage rate, so as to maintain the water bath in the warming chamber at a substantially constant water level, so that, when the pump is turned off, the water substantially drains from the warming chamber to the reservoir, thus substantially removing the water from contacting the bottle.
