The waveguide 4 is provided at one end of the waveguide 4 connected to the waveguide 4.
A heater 5 for heating food and a steam outlet 6 for discharging high-temperature steam are provided in the heating chamber 2, and the food 8 on a saucer 7 on the bottom of the heating chamber is heated by the heater and heated by steam. The waveguide 4 is installed on the heating chamber ceiling surface 9 so that its tube axis is perpendicular to the heating chamber ceiling surface 9, and is located near the antenna 10 of the high frequency oscillator 1 coupled to the waveguide 4. A plurality of small holes 13 and 14 are formed in the side tube wall 12 of the waveguide 4 between the termination surface portion 11, the high-frequency oscillator 1, and the high-frequency supply port 3, respectively, along the electric field vector direction 16 generated within the waveguide 4. One row is provided for each. A partition plate 1 made of a silicon laminate with low dielectric loss is installed at the high frequency supply port 3 on the ceiling surface 9 of the heating chamber to prevent foreign matter from entering the waveguide 4.

The high frequency energy generated by the high frequency oscillator 1 passes through the waveguide 4 and is irradiated onto the food 8 in the heating chamber 2 from the high frequency supply port 3 to dielectrically heat the food. On the other hand, the food is externally heated by radiant heat from a heater 5 provided near the ceiling surface 9 of the heating chamber and high-temperature steam from a steam outlet 6. During dielectric heating using high-frequency energy, the temperature inside the heating chamber is low, but when the heater is heated, the temperature inside the heating chamber becomes high (150° to 250°). At this time, some high-temperature air enters into the waveguide 4 through the gap between the high-frequency supply port 3 and the shikiri plate 15, and the vicinity of the terminal end surface 11 of the waveguide 4 is filled. However, small holes 13 and 1 are formed in the side tube wall 12 of the waveguide 4 between the antenna 10 vicinity of the termination surface portion 11 and the high frequency oscillator 1 and the high frequency supply port 3.
4 are provided in one row along the electric field vector, this high-temperature air can be efficiently discharged to the outside along the air flow shown by the arrow in the figure without causing radio wave leakage.
Similarly, when high-temperature steam is blown into the heating chamber 2 for cooking, the steam can be discharged to the outside through the small holes 13 and 14.

Since it is installed along the direction of the electric field vector generated within the waveguide, the high temperature air and steam can be efficiently discharged to the outside without causing radio wave leakage, preventing thermal damage when heating the heater of the high frequency oscillator, and preventing the antenna from being damaged by steam. Sparks caused by corrosion at the base are prevented.
