Abstract
A waterproof food temperature probe includes a penetrating portion for inserting into food during cooking; a cable for coupling the penetrating portion to a display unit separated from the penetrating portion; and, a high temperature resistant seal portion permanently covering at least part of the penetrating portion and at least part of the cable. The seal portion prevents moisture from entering the penetrating portion thereby preventing the temperature probe from malfunctioning.
Claims15
A waterproof thermometer probe, comprising:
- a penetrating portion for inserting into food during cooking, the penetrating portion comprising a hollow tube and a temperature sensor located within the hollow tube at a first end, the hollow tube forming a protrusion extending radially therefrom at a second end opposite to the first end;
- a cable (i) protecting electrical wires therein and (ii) coupling the temperature sensor to a display unit separated from the penetrating portion;
- and,
- a high temperature resistant seal portion permanently covering (i) part of the penetrating portion at the second end of the hollow tube, and (ii) at least part of the cable to provide a first moisture barrier preventing water from entering the hollow tube portion, the high temperature resistant seal portion surrounding the protrusion to prevent separation of the seal portion from the penetrating portion;
- a non-stick coating covering the hollow tube where the high temperature resistant seal portion is not covering the hollow tube.
A method for manufacturing a waterproof thermometer probe, the method comprising:
- forming a hollow tube portion of the probe, the hollow tube forming a protrusion extending radially therefrom at a first end;
- positioning a temperature sensor within the hollow tube portion proximate a second end;
- electrically coupling a cable through the hollow tube portion to the temperature sensor, the cable protecting electrical wires therein;
- and
- molding a high temperature resistant seal portion around a portion of the cable entering the hollow tube portion, and around part of the first end of the hollow tube portion, the high temperature resistant seal portion surrounding the protrusion to prevent separation of the seal portion from the hollow tube portion;
- and,
- applying a non-stick coating to the hollow tube portion such that the non-stick coating covers the hollow tube where the high temperature resistant seal portion is not covering the hollow tube.
