20130319257 | ELECTRICAL APPLIANCES WITH THERMOCHROMIC INKS APPLIED IN HIGH VISIBILITY AREAS AS THERMAL STATE INDICATOR MECHANISM - Electrical appliances comprising thermochromic inks in zones of high visibility for the user are disclosed, as a mechanism to know by simple observation their thermal state (cold or hot). Said electrical appliances correspond to any appliance that uses electricity as a mechanism to generate useful thermal energy for either food processing (sandwich maker, rice cooker, ovens, roasters) or home maintenance (iron, stove, among others), and therefore during its use may reach a dangerous temperature for the physical integrity of the persons handling it. Thermochromic and photochromic inks are applied in zones of the electrical appliances, where the user may easily see the color change during use, as in zones where there is no direct contact with food and wherein it is appropriate to notice the possibility of burns by hot surfaces, which, depending on the type of electrical appliance can be in upper or side surfaces of such appliances. | 12-05-2013 |
20140349846 | KITCHENWARE WITH THERMOCHROMIC AND PHOTOCHROMIC INKS APPLIED IN HIGH VISIBILITY AREAS AS THERMAL STATE INDICATOR MECHANISM - Kitchenware comprising thermochromic and photochromic inks in zones of high visibility for the user are disclosed, as a mechanism to know by simple observation their thermal state (cold or hot), independently if said kitchenware is used outdoors (under sunlight exposure) or in enclosed areas. Said kitchenware corresponds to pots, frying pans, cooking pots, pressure cookers or any other kitchen utensil whose use may be outdoors or in enclosed areas and implies direct or indirect contact with a thermal energy source. Thermochromic and photochromic inks are applied in zones of the kitchenware where the user may easily see the color change during use, as in zones where there is no direct contact with food, which, depending on the type of kitchen utensil, may be in covers, knobs, grippers, handles, flame arrestors, regulator valves for pressure cookers, as in exterior walls that are not in direct contact with the thermal source. | 11-27-2014 |
