PURPOSE:To reduce temperature difference between a heater and a cooker to realize function similar to a kitchen range and a pot or to a low range by a method wherein a heat pipe for facilitating thermal transfer at least between the heater and the side wall of the cooker. CONSTITUTION:A heat pipe 8 embedded on a side wall 9 between a pot 10 and a coil 7, and a heater 1 of a rice cooker not only increases heat conduction area but also heats the pot from the bottom as well as applies heat from the side wall 9. As a result, difference in temperature between the heater and a cooker can be extremely small so that a cooking device similar to a conventionally Japanese kitchen range and a pot or to a conventionally Western low range is realized. In addition, a coil 7 comprises six electromagnetic induction coils A1 to A6 while they are connected by means of desirably in three-phase double delta connection. |
