Abstract
A handle (20) for cooking utensils, particularly pots or pans, of the type designed to be joined to the edge of the utensil (10), is made of a material, with low heat conductivity and equipped with an elongated plate (30) made of a material with high heat conductivity, having one terminal section in thermal contact with the body of the utensil (10) and the other end far from it, and with thermo-chromatic means (40) applied on the plate (30) and preferably consisting of crystals having (42a-42f) the ability to change color within predetermined ranges of temperature, so as to display information, related to the temperature of the bottom of the utensil, in different areas of the plate (30).
Claims2
A handle (20) for cooking utensils (10), in particular pots or pans, to be joined to the edge (12) of the utensil (10), said handle (20) being made with a material having low heat conductivity and comprising:
- a) a plate (30) in a material having heat conductivity, said plate (30) having a part of one end (32) in thermal contact with the edge (12) of the utensil (10) and the other end (34) at a distance from it and
- b) thermo-chromatic means applied in contact with different areas of the plate (30) and having the ability to change colour within predetermined ranges of temperature,
- the change in the temperature along the plate (30), caused by the change in the temperature of the bottom of the utensil (10), will in turn cause the change in colour of the thermo-chromatic means and the display of information related to the temperature of the bottom of the utensil (10) on different areas of the plate (30), characterised in that the thermo-chromatic means are crystals (42a-42f) that show a specific colour outside of the range of temperature at which they are activated and become transparent within that range, whereby areas of the plate (30) increasingly distant from the body of the utensil (10) reaching the temperature at which the thermo-chromatic crystals (42a-42f) are activated and become transparent, as the temperature of the bottom of the utensil (10) increases, and viceversa as the temperature of the bottom of the utensil (10) decreases.
