The air discharge operation in the cooker will be described.

First, when the pump motor 22 is operated by the main control circuit (not shown in the figure) of the cooking apparatus, air in the cooking apparatus is sent to the air delivery pipe 23 through the exhaust port 21. Subsequently, when the pump motor 22 is driven, the air in the cooking chamber (hereinafter referred to as "indoor") is discharged to the outside by the exhaust pump, and the room becomes almost vacuum (at this time, the suction port is a damper cover system). Blocked by). Therefore, the air sent out from the exhaust pump flows into the concave foreign matter storage portion 24 located at the discharge port so that foreign matter contained in the air is collected by the foreign matter storage portion 24. The air passing through the foreign matter storage unit 24 is discharged to the outside via the air filter 25 and the outdoor air exhaust port 27. The air filter 25 may be formed of an antibacterial filter capable of removing germs or a deodorizing filter capable of removing odors for the purpose of upgrading the product. In the example of FIG. 2, the foreign material storage unit 24 illustrates a structure in which the foreign material storage unit 24 is separated from the air exhauster composed of the air filter 25, the air duct 26, and the external air vent 27. As described above, the foreign material storage unit 24 and the air discharge unit may have a structure formed integrally with each other.

In addition, as shown in FIG. 2, since the foreign material storage part 24 is made of a transparent and flexible plastic material, it can be freely separated from the cooking body 100. The direction perpendicular to the rear surface of the cooking body 100 is shown.
