Heating cooking device

摘要

A heating cooking device includes a temperature sensing element that contacts a bottom surface of a top plate directly or indirectly and measures a temperature of the top plate, a spring portion one end side of which is supported by a heater unit and the other end side of which presses the temperature sensing element against the top plate, and a spring that presses the heater unit toward the top plate. An elastic force n1 with which the spring portion presses the temperature sensing element against the top plate is smaller than an elastic force n2 with which the spring presses the heater unit toward the top plate.

主权项

1. A heating cooking device, comprising:
a top plate with a cooking container placed on a surface thereof; a radiant heater that is placed at a predetermined distance from the top plate; a spacer that is provided between the top plate and the radiant heater, and defines the predetermined distance; a temperature sensing element that contacts a bottom surface of the top plate directly or indirectly and measures a temperature of the top plate; a first elastic body, one end side of which is supported by the radiant heater, and the other end side of which presses the temperature sensing element against the top plate; and a second elastic body that presses the radiant heater toward the top plate, wherein an elastic force N1 with which the first elastic body presses the temperature sensing element against the top plate is smaller than an elastic force N2 with which the second elastic body presses the radiant heater toward the top plate, wherein the radiant heater includes a heating coil, and a base portion that is made of a heat insulator and supports the heating coil, the first elastic body is configured by a pair of spring pieces made of metal, a pair of lead wires that transmit an electrical signal from the temperature sensing element are connected to the pair of respective spring pieces, the temperature sensing element being supported on a supporter of ceramics that is fixed to one end side of each of the spring pieces, and a pair of legs made of metal that are integrally joined to or connected and joined to the respective spring pieces are led out to a bottom side of the base portion through the base portion.
