[0034] The central control system of the present invention is equipped with a self-cleaning mode. After the tableware is cleaned, the self-cleaning mode is manually or automatically turned on, and the self-cleaning structure in the cabinet starts to work immediately, without the need for special cleaning equipment.

[0035] The self-cleaning mechanism equipped with the washing machine of the present invention is used to clean the residual soup left by the equipment, and the self-cleaning and tableware cleaning are controlled by the central control system to realize switching.

[0036] The cleaning method of the instant type self-service washing machine of the present invention comprises the steps:

[0037] (1) After the customer has finished eating, directly turn the tableware upside down and place it flat on the washing machine delivery area. The rotors of adjacent rollers in the delivery area are arranged in a staggered manner, and part of the residue in the upside-down tableware passes through the rollers. When conveying, it falls from the gap between the rotors to the residue collection box below;

[0038] (2) The tableware entering the slag removal area is cleaned by the brush-type water spray roller and under the action of water spray, most of the residue in the tableware falls into the residue collection box below;

[0039] (3) The tableware entering the washing area is washed by high-pressure water, and the remaining residues in the tableware are completely peeled off, and the residues fall into the metal cage above the sink;

[0040] (4) The tableware entering the cleaning area is washed with high-temperature hot water, the residual washing liquid on the tableware is rinsed, and the tableware is subjected to high-temperature disinfection;
