Claims

[Scope of utility model registration request]

A storage chamber for electrical components is formed between the case and the heating chamber,
A lock switch that partitions the interior of the storage chamber and the heating chamber, protects the interior of the storage chamber from radiant heat from the heating chamber, and is linked to the opening/closing operation of the opening/closing door and stops high-frequency oscillation when the opening/closing door is opened. In the high-frequency heating device, the high-frequency heating device is equipped with a heat shield plate to which a duct is attached, and a duct that guides cooling air that cools a high-frequency oscillator into the heating chamber through a duct insertion hole in the heat shield plate. A part of the peripheral edge is provided with a cut-and-raised piece that is cut and raised toward the heating chamber, and a duct component that constitutes the duct is provided with a cut-and-raised piece along with the cut-and-raised piece between the heat shield plate and the heating chamber. A high-frequency heating device characterized by being provided with an extension that forms a ventilation path.
