DISHWASHING MACHINES AND ITS SERVICE METHOD Russian patent published in 2009 - IPC A47L15/00 A47L15/48 

FIELD: articles for personal use.

SUBSTANCE: this invention refers to the dishwashing machine and its service method. The dishwashing machine consists of the washing chamber, the dish washing devices with the cleaning solution and sorption dry device linked to the washing chamber with the air passage capability. It has sorption column with reversible dry material used for dish drying. The machine has the sensor for determination of the condition of the reversible dry materials during the washing program to affect the passage of the washing program depending on the reversible dry material's condition. The sensor is located mostly in the sorption drying device. According to the service method of the dishwashing machine having at least one “Drying” sub-program, the program provides that the air is conducted from the washing chamber of the dishwashing machine and/or from the outside environment through the sorption column to the washing chamber. The column contains reversible dry material. When the air passes the sorption column it is dehydrated. The temperature of the air passed through the sorption column is measured within the sorption column or after it in order to set the termination of the “Drying” sub-program upon the measured degree of the temperature or measured degrees of the temperature. In version of the method the humidity of the air passed through the sorption column is measured within the sorption column or after it in order to set the termination of the “Drying” sub-program upon the measured degree of the humidity or measured degrees of the humidity.

EFFECT: invention improves the efficiency of the cleaning and drying of the dishes and maintenance of the power expenditures at the lowest possible level.
