Integration of surface heating to an enclosure
View Patent ↗Disclosed are designs and methods for integrating heating film onto surfaces and enclosures that are useful for preventing the infestation of pests. Specifically, designs to increase the effective heating area and location of said heating film within enclosures such as suitcases. Also, the use of heating films to create a thermal barrier to prevent pests from crawling across a surface. Heating films can be utilized that are inexpensive, low-profile, and lightweight.
1. A system for eliminating pests in connection with heatable materials, the system comprising:
an enclosure adapted to receive heatable materials, the enclosure having an exterior portion and an interior portion, the interior portion forming an interior compartment, the interior portion including walls having an interior surface defining the interior compartment; and
an infrared heating film integrated into the enclosure, the infrared heating film comprising a bus bar and a plurality of side heat channels to provide a heating area extending beyond the bus bar;
wherein the infrared heating film comprises an outer portion and an inner portion disposed radially inward of said outer portion, the heating film also comprising a first bus bar, a second bus bar, an outer side heat channel and an inner side heat channel,
wherein the outer side heat channel connects the first bus bar to the second bus bar along a path in the outer portion of the heating film, and wherein the inner side heat channel connects the first bus bar to the second bus bar along a path in the inner portion of the heating film,
wherein the outer side heat channel is larger than the inner side heat channel, and
wherein the infrared heating film is operable to kill pests at all locations within the interior compartment.
2. The system of claim 1 , wherein the side heat channels comprise carbon-graphite deposits.
3. The system of claim 2 , wherein the heating element is integrated into at least one wall of the interior portion of the enclosure.
4. The system of claim 3 , wherein the side heat channels are arranged to minimize the non-heated area in the at least one wall of the interior compartment.
5. The system of claim 4 , wherein the interior portion of the enclosure comprises six walls, and the heating element is integrated into all six walls of the interior portion.
6. The system of claim 1 , wherein the enclosure comprises a first exterior pocket on the exterior portion of the enclosure, and wherein the infrared heating film is adapted to kill pests within the first exterior pocket.
7. The system of claim 6 , wherein the enclosure comprises further comprises a second exterior pocket on the exterior portion of the enclosure, and wherein the second exterior pocket is not heated by the infrared heating film.
8. The system of claim 7 , wherein the second exterior pocket comprises an insulation layer used to reduce heat from an infrared heating film from penetrating the second exterior pocket.
9. The system of claim 1 , wherein the enclosure is a suitcase.
10. The system of claim 9 , wherein the suitcase comprises at least one suitcase divider, and wherein the infrared heating element is located within the suitcase divider.
11. The system of claim 10 , further comprising a tilt sensor to determine orientation of the enclosure.
