Further, since the control means is arranged to add the alkaline agent after a lapse of a predetermined time from the start of cleaning, the stains firmly adhered by the alkaline agent can be removed after the cleaning effect of the microbial preparation is sufficiently exerted. It is possible to prevent the microbial preparation from being killed by the addition of the alkaline agent and the cleaning effect thereof being lowered.

Further, since the storage space for storing the microbial preparation is provided and the control means automatically puts the microbial preparation into the washing tank, the inside of the washing tank and the inside of the pipe can be easily washed.

Further, since the control means is configured to continue the in-room cleaning course after the standard course for cleaning the dishes is completed, the inside of the cleaning tank and the pipe can be cleaned every time the dishes are cleaned, It is possible to prevent dirt from accumulating.
