In addition, when the food pieces accumulated in the filter portion 45b are forgotten to be removed after washing the cooking chamber 20, the air in the cooking chamber 20 passes through the side surface of the water passage cylinder portion 45b2 of the filter portion 45b of the drain perforated plate 45, Since it is discharged from 1 drain pipe 15, it was possible to prevent the inside of the cooking chamber 20 from becoming a positive pressure.

In addition, a restricting portion 45b1 is arranged at a position close to the inner peripheral surface of the first drain pipe 15 on the upper portion of the filter portion 45b to restrict the horizontal movement of the drainage mesh plate 45. As shown in FIG. When the inside of the cooking chamber 20 is being washed, the washing water is scattered in the cooking chamber 20 by the convection fan 26, and there is a possibility that the drain perforated plate 45 will come off from the drain port 20c together with the scattered washing water. However, since the regulating portion 45b1 of the filter portion 45b is fitted to the inner peripheral surface of the first drain pipe 15 with a small gap, the drain mesh plate 45 is less likely to come off from the drain port 20c.

In addition, an inclined portion 45b3 whose diameter becomes smaller toward the lower side is provided on the upper side of the water passage tube portion 45b2 of the filter portion 45b. When inserting the filter portion 45b of the drain perforated plate 45 into the first drain pipe 15 from the drain port 20c, the upper side of the water passage cylindrical portion 45b2 is prevented from being caught on the peripheral portion of the drain port 20c and deformed.

In addition, an auxiliary filter 46 is provided below the drain perforated plate 45 in the first drain pipe 15 that constitutes the washing water pipeline. As a result, even if the drain perforated plate 45 is disengaged from the drain port 20c, foreign matter is prevented from flowing into the pump 42 through the first drain pipe 15.例文帳に追加Furthermore, since the stand portion 45c also serves as a handle portion, the drainage perforated plate 45 can be easily attached and detached by gripping the stand portion 45c.

The drainage perforated plate 45 is not limited to the embodiment shown in FIG. 9, and as shown in FIG. good too.
