The ones shown in 5 and 6 were common. The object to be heated 1 is placed on a metal tray 5 and a turntable 6 made of a microwave transmitting material in the center of the heating chamber 2, and the object to be heated 1 is cooked by the microwave supply device 3. Generally, the mesh shape of the metal tray 5 is set to a size and a shape that reduces heating unevenness of the article 1 to be heated. Most metal trays 5 of the high-frequency heating apparatus with a toasting function employ a grid-like mesh shape as shown in FIG.

の加熱効率は悪くなっている。However, in the conventional high-frequency heating device, the hole shape of the metal tray 5 is lattice-shaped, so that when the metal tray 5 rotates, the angle of the metal tray 5 changes. , Microwave supply device 3
The reflection of the microwave from the heater changes, and the impedance in the heating chamber 2 changes. In particular, since the lattice-shaped crosspiece is formed with respect to the outer periphery or the circular outer shape of the metal tray 5, the holes become odd-shaped, so that the impedance change is further increased. FIG. 6 is a diagram in which a change in impedance when the object to be heated is placed at the center of the metal tray 5 and rotated is plotted on a Smith chart. From this, it can be seen that the actual operation range exceeds the impedance range in which the maximum output can be obtained from the microwave supply device 3. Therefore, the heating efficiency of the object to be heated is deteriorated.
