Abstract

The present invention provides a heating cooker capable of improving the assembling accuracy of a trap for restrain electromagnetic wave leakage and making it difficult to rust, which includes: a heatchamber for loading food; a microwave generating device for providing microwave to the heat chamber; a concave part formed in the heat chamber; a heater mounting hole formed on the lateral wall of the concave part; a tubular heater inserted in the heater mounting hole; and a trap provided outside the concave part and located surrounding the end of the tubular heater. In addition, the heating cooker also includes a wave-resisting tube for the inserting of the heater located outside the concave part of the heater mounting hole; a base integrated with the wave-resisting tube and fixed outside the concave part located at the surrounding of the heater mounting hole; a wave-resisting tube support portion for pressing the base on the lateral wall of the concave part; and a metal cover for covingthe wave-resisting tube at the external side of the concave part. The trap is compoded of the metal cover, the wave-resisting tube and the wave-resisting tube support portion.

Description

technical field [0001] The invention relates to a heating cooker for heating food and a manufacturing method of the heating cooker. More specifically, it relates to a microwave oven with a grill that can not only provide microwaves to the heating chamber for induction heating of food, but also can use A heating cooker provided with a tubular heater such as an argon lamp heater to heat food, and a method for manufacturing the heating cooker. Background technique [0002] The above-mentioned heating cooker can not only inductively heat the food as the object to be induced by the microwave emitted by the magnetron, but also can perform radiation heating by the tubular heater as required. The tubular heater here can adopt devices such as a ceramic heater (or a coil heater) configured with a coiled filament in a heat-resistant glass tube, or an argon lamp heater provided with a linear electric heating wire. [0003] In addition, when the tubular heater is installed to penetrate ...
