Abstract:
1. A dishwashing machine comprising: a washing container; at least one device for washing crockery using a washing solution in accordance with a washing programme; a sorption drying device communicated with the washing container for the passage of air between the sorption drying device and the washing container, the sorption drying device containing reversibly dehydratable material that operates to withdraw moisture from air during the passage of the air through the sorption drying device in a substantially closed loop “drying” partial programme stage of the washing programme, the stage comprising air exiting from the washing container via a washing container exit outlet, thereafter flowing into the sorption drying device and along a flow path through the sorption drying device, and eventually exiting the sorption drying device to return to the washing container via a washing container entrance inlet; and a sensor to measure a condition of the reversibly dehydratable material at least during the substantially closed loop “drying” partial programme stage of the washing programme, and a control unit to record the at least one measured condition of the reversibly dehydratable material, wherein the control unit is programmed and configured to: (1) correlate the measured condition of the reversibly dehydratable material to a dryness of the crockery in the washing container; and (2) terminate the “drying” partial programme stage of the washing programme if a recorded condition of the reversibly dehydratable material reaches a threshold value.
