Title: Device for detecting temperature of food
Inventor: TANAKA SUMIKO
IPC: G01K1/14
Filed: 1993-07-07
Abstract: PURPOSE:To correctly measure a temperature of a food without being affected by the shape of the food, by forming a bowl, the inside of which is hollow, out of deformable raw material, sticking the food fast to the bowl, and detecting the temperature of the food by a temperature sensor installed in the bowl. CONSTITUTION:When a food 18 to be thawed is placed on a thawing bowl 19, the bowl 19 is deformed to a shape in which the bottom of the food 18 adheres closely to the bowl 19. When thawing is started, the heat of a radiant heater 15 arrives directly in the food 18 and indirectly through a reflecting plate 13. The temperature of the food 18 is detected by a temperature sensor 16 through the bowl 19 and a bottom plate 14. The temperature of the food 18 is correctly transmitted to the sensor 16 and the dispersion by a shape of the food 18 becomes small, because the gap between the sensor 16 and the food 18 is made smaller by the deformation of the bowl 19. When a nonfreezing solution is enclosed in the cavity of the bowl 19, the adherence degree thereof with the food 18 is increased, and the accuracy of measurement is improved.
