At this time, the heating member 118 starts to operate, and when the cleaning medium in the tray 116 is heated to a certain temperature, for example, the cleaning medium in the tray 116 is heated to 60 degrees, the heating member 118 stops operating. At this time, the first pressurizing member 110 connected to the circulation circuit 108 is operated to pump the heated cleaning medium in the tray 116 to the spray head 128, and the spray head 128 sprays the heated cleaning medium into the cleaning space 106 and cleans the cleaning space 106. The cleaning medium flows back into the tray 116, at which time the cleaning space 106 may be continuously cleaned or the cleaning medium in the tray 116 may be discharged to the outside of the cabinet 100. Finally, the filter screen 120 is taken out, and the impurities on the filter screen 120 are removed or the filter screen 120 is replaced. Thereby, the cleaning of the cleaning space 106 is completed.
