Abstract

A rechargeable thermometer system is disclosed having a rechargeable thermometer and a charging assembly. The rechargeable thermometer is releasably engageable with the charging assembly, which in turn can be plugged into a household electrical outlet to provide charging electricity to a rechargeable battery housed within the thermometer. The thermometer is electrically connectable to the charging assembly to receive a charge so that when the thermometer is separated from the charger it can be used to sense the temperature of a food product into which the thermometer probe tip is introduced. The charging assembly has a pass-through plug to allow household appliances to be plugged into charger to receive electrical energy from the household outlet into which the charger itself is plugged. The thermometer can be held by the charger when not in use, thus ensuring the thermometer will always be fully charged prior to use.

12. A rechargeable temperature monitoring system, comprising:

a rechargeable thermometer having a probe portion with a piercing tip disposed at a distal end of said probe portion, a display portion, a neck portion disposed between the probe portion and the display portion, a rechargeable battery, and an electrical charge receiving surface;

a charging portion being releasably connectable with the neck portion of said rechargeable thermometer, said charging portion comprising a casing and plug assembly for engaging an electrical outlet to receive electrical current therefrom, said charging portion further comprising an electrical charging surface;

wherein the plug is fixed to the casing to support the charging assembly and thermometer above a work surface when the plug is engaged with the electrical outlet; and

wherein when said rechargeable thermometer is received by said charging portion, said electrical charge receiving surface contacts said electrical charging surface to conduct electricity from said electrical outlet to said rechargeable battery.

1. A rechargeable food monitoring system, comprising:

a thermometer having a probe portion, a display portion, a neck portion disposed between the probe portion and the display portion; and

a rechargeable battery electrically connected to a charge receiving surface, said battery configured to provide operating power to said thermometer;

a charging assembly having a casing comprising a recess for engaging the neck portion of the thermometer, a plug for engaging an electrical outlet, and a charging surface configured to contact said charge receiving surface of said thermometer when said thermometer is engaged with said charging assembly;

wherein the casing further comprises a plug fixed to the casing to support the charging assembly above a work surface when the plug is engaged with the electrical outlet;

wherein the charging surface is electrically connected to the plug to conduct electricity from the electrical outlet to the battery via contact between the charging surface and the charge receiving surface when the thermometer is engaged with the charging assembly.

2. The system of claim 1, the charging assembly further comprising a plug receiving element configured to allow an auxiliary electrical device to be plugged into said charging assembly;

wherein the plug receiving element is disposed within the casing.

3. The system of claim 1, further comprising a detent for releasably connecting said thermometer to said charging assembly.

4. The system of claim 3, wherein said detent comprises a magnetic detent.

7. The system of claim 1, wherein said charging assembly comprises an indicator to signal when said battery of said thermometer is charged by a predetermined amount.

9. The system of claim 1, wherein said display portion comprises an indicator for indicating when said thermometer measures a preselected temperature.

10. The system of claim 9, wherein said preselected temperature is variably selectable by a user.

13. The system of claim 12, the casing further comprising a plug receiving element configured to allow an electrical device to be plugged into said charging assembly to receive electrical current from said electrical outlet when said plug assembly is engaged with said electrical outlet.

14. The system of claim 12, further comprising a detent for releasably connecting said rechargeable thermometer to said charging portion.

15. The system of claim 14, wherein said detent comprises a magnetic detent, the magnetic detent comprising a first magnetic element disposed on the neck of the rechargeable thermometer and configured to releasably connect to a second magnetic element disposed on the charging portion.

18. The system of claim 12, wherein said charging portion comprises an indicator for signaling when said rechargeable battery is charged by a predetermined amount.

19. The system of claim 12, wherein said rechargeable thermometer further comprises a display portion for displaying a temperature measured by said rechargeable thermometer.

20. The system of claim 19, wherein said display portion comprises an indicator for indicating when said thermometer measures a preselected temperature.

21. The system of claim 20, wherein said preselected temperature is variably selectable by a user.

23. The system of claim 1, wherein the recess in the casing is shaped to conform to a corresponding surface on the neck of the thermometer.

24. The system of claim 1, wherein the recess comprises a first portion that engages the neck portion of the thermometer and a second portion for receiving at least a portion of the probe portion of the thermometer.

25. The system of claim 1, wherein the charge receiving surface is disposed on the neck portion.

26. The system of claim 4, wherein the magnetic detent comprises a first magnetic element disposed on the neck portion of the thermometer.

27. The system of claim 26, wherein the magnetic detent further comprises a second magnetic element disposed within the recess to engage the first magnetic element.

28. The system of claim 12, further comprising a sheath that overlies the probe portion and the piercing tip when the thermometer is engaged with the housing.

29. The system of claim 28, wherein a portion of the sheath is received within a portion of the recess when the thermometer is engaged with the charging assembly.

30. The system of claim 12, wherein the charging assembly comprises a recess for receiving the neck portion of the rechargeable thermometer, the electrical charge receiving surface is disposed on the neck portion, and the electrical charging surface is disposed in the recess of the charging portion.

16. -17. (canceled)

22. A rechargeable food monitoring system, comprising:

a rechargeable thermometer having a probe portion, a display portion, an electrically conductive surface, and a rechargeable battery electrically connected to said electrically conductive surface; and

a charging assembly comprising a casing with a recess for receiving at least a portion of said rechargeable thermometer, and a plug portion for engaging an electrical outlet to receive electrical current therefrom, said charging assembly further comprising a charging surface disposed within said recess for contacting said electrically conductive surface of said rechargeable thermometer when said rechargeable thermometer is received within said recess to thereby transfer an electrical current from said electrical outlet to said rechargeable battery;

wherein said charging assembly has a first detent element to lock said rechargeable thermometer to said charging assembly, said first detent element disposed adjacent to said charging surface within the recess of the casing.

33. The system of claim 22, wherein said casing further comprises an electrical socket element for receiving a plug of an electrical device, said electrical socket element being integral with said casing and allowing said electrical device to receive electrical current from said electrical outlet.
