Abstract (en)
The present disclosure relates to a method for automatically evaluating the degree of cleanliness of the filtering system in a dishwashing machine (1) comprising a washing zone (2) provided with a washing fluid collection zone (2"') in which a filter (F) is positioned, comprising steps of: acquiring (11) a first digital image (11A) representative of a first condition of the filter (F), digitally processing (12) the first digital image 11A so as to obtain a first processed image 11B, wherein the first processed image (11B) identifies a first surface value related to the surface area of the collection tank (F") of the filter (F) in a first condition in which the filter (F) is clean, acquiring (13) a second digital image (13A) representative of a second condition of the filter (F), digitally processing (14) the second digital image (13A) so as to obtain a second processed image (13B), wherein the second processed image (13B) identifies a second surface value related to the surface area of an accumulation of dirt present in the collection tank (F") in a second condition in which the filter (F) contains an accumulation of dirt, comparing (15) the second surface value with the first surface value to calculate an occlusion percentage value (OCL) of the filter (F) when passing between the first condition and the second condition, generating (16) a dirt presence signal (Sig) indicative of the presence of an accumulation of dirt in said filter (F), when the occlusion percentage value (OCL) of the filter (F) exceeds a predefined threshold value, generating (17) a sound and/or visual signal indicative of an obstructed filter condition, when the dirt presence signal (Sig) is generated.
