  FIG. 3 is a schematic cross-sectional view for explaining the air flow outlet 9 provided in the tableware washing apparatus 1 of the first embodiment. The airflow blowing unit 9 has an air outlet 9a that blows out an airflow. The blower outlet 9a has a slit shape extending in the left-right direction of the tableware washing apparatus 1, that is, the direction perpendicular to the paper surface of FIG. When the blower fan 6 is operated, a part of the airflow generated by the blower fan 6 flows through the air passage 10 to the airflow blowing unit 9 and is blown out from the blowout port 9a.

  When the drawer 50 detects that the cleaning tank 3 is pulled out from the housing 2 after the cleaning is started, the control device 50 operates the blower fan 6 and blows out the air outlet 9a of the air flow outlet 9. Blows airflow from. When the washing tub 3 is pulled out from the housing 2, the air flow blown out from the air outlet 9 a is blown against the lower surface of the lid body 4, and the air flow blowing portion 9 moves leftward in FIG. 3 along the lower surface of the lid body 4. Move to. While the air flow blowing portion 9 moves with respect to the lid body 4 while blowing the air flow from the air outlet 9a onto the lower surface of the lid body 4, the water droplets 90 attached to the lower surface of the lid body 4 are removed from the lower surface of the lid body 4. , And falls into the space in front of the airflow blowing portion 9, that is, the internal space of the cleaning tank 3. When solids such as food residue (hereinafter simply referred to as “food residue”) adhere to the lower surface of the lid 4, the food residue is also removed from the lower surface of the lid 4 by the air current.

  As described above, the following effects are obtained by removing the water droplets 90 and the food waste adhering to the lower surface of the lid 4. It is possible to reliably prevent the water droplets 90 and food waste adhering to the lower surface of the lid body 4 from falling to the rear of the cleaning tank 3.
