- the term changes made to one or more of said cleaning parameters of the cleaning program P is intended to designate any change to the parameters of the program parameters P as a result of the identification of the type of detergent.
- the method of automatically assessing the type of detergent in use in the dishwashing machine 1 comprises a step 10 of providing a detergent D1, D2, D3 in the dispenser 6, with the user placing the detergent he/she has selected in the compartment of the dispenser 6.
- the method comprises the step 11 of acquiring a first digital image 11A representative of the detergent D1, D2, D3.
- the method steps as described hereinbelow i.e. the steps of acquiring and processing may be carried out either directly by the CPU of the control unit 4 or more preferably by the CPU of the portable user device via the Internet connection with the CPU of remote servers for analysis and data processing.
- This acquisition step 11 is carried out through the optical device/s 8 located in the washing area 2.
- control unit 4 supervises the acquisition step by controlling the optical device/s 8.
- the acquired image 11A preferably comprises a burst of images and hence more than a single frame.
- the burst of images is advantageous because, once the door 7 of the dispenser 6 has been moved from the closed position to the open position, the detergent D1, D2, D3, is moved by gravity from the dispenser 6 to the washing area 2. Therefore, by acquiring multiple images 11A by the optical device/s 8 multiple frames 11A that depict the detergent D1, D2, D3 are obtained.
- the preferred number of frames that make up the burst of images 11A is equal to or greater than three, preferably equal to four, five or six.
- the image 11a is acquired when the door 7 of the dispenser 6 moves from the closed position to the open position.
- the acquisition step 11 is carried out during the time interval between the time at which the door 7 is opened and the time at which the detergent D1, D2, D3 is released into the washing area 2 of the dishwashing machine 1.
- the time interval in which the optical device 8 must acquire the image 11A is equal to or smaller than one second.
- the method comprises a step 12 of digitally processing the first acquired image 11A to obtain a first processed image 12A, in which such first processed image 12a identifies either:
- control unit 4 and/or the user-held portable device are used to start a process in which the first image 11A is processed to identify at least a portion of the contour Cpar of the detergent or the roughness value Racq of the detergent.
- the at least a portion of the contour Cpar is identified in case of a tab detergent D1 or a powder detergent D2, whereas the roughness Racq is identified in case of a powder detergent D2, or a liquid/gel detergent D3, as described below.
- the method comprises a step 13 of comparing the at least a portion of the contour with a predetermined contour Cpred or comparing the roughness value with a roughness threshold value Rth to define a type TD of detergent.
- the comparison step 13 may be implemented, for instance, by comparing the various portions of detergent that have been imaged with the contours of the tabs or the roughness values that have been previously stored in a database residing in the memory of the control unit 4 or in the memory of the user-held portable device or in a server remote from both the dishwashing machine 1 and the user handheld portable device.
- the contours of the tabs 5 and/or the roughness value are known to the manufacturer of the dishwashing machine 1 and can be stored beforehand and directly compared with those in the first processed image 12A.
- This comparison step 13 will result in the definition of the type of detergent TD1, TD2, TD3, i.e. The recognition of a tab, powder or liquid/gel detergent, respectively.
- the method comprises a step 14 of changing one or more of the cleaning parameters of the cleaning program P according to the type of detergent.
- the cleaning parameters of the cleaning program P that can be changed according to the type of detergent that has been detected are one or a combination of more than one of the following parameters:
- the parameters of the cleaning program P that can be changed vary according to whether a liquid detergent D2/D3 or a tab detergent D1 has been recognized.
- the program P operates the washing pump and the heating resistor for a first predetermined time interval, e.g. a few minutes, and then continues with the washing operation for a second time interval, that is longer than the first time interval.
- the next rinsing step includes a washing and heating step whose duration is equal to a third time interval, shorter than the first time interval.
- the program P operates the washing pump and the heating resistor for a first time interval and then continues with the washing operation only for a second time interval, that is shorter than the first time interval.
- the next rinsing step includes a washing and heating step whose duration is equal to a third time interval, that is shorter than the first and second time intervals.
- the comparison step 13 when comparing the at least a portion of the acquired contour Cpar with a predetermined contour Cpred, comprises a step of checking such said at least a portion of the acquired contour Cpar is analogous to the predetermined contour Cpred, to thereby determine the type of detergent TD1, such as a detergent tablet, i.e. a tab D1.
- the term analogous is intended to designate the case in which the portion of the acquired contour Cpar is comparable or similar, within a predetermined percent deviation, with the tab contour that has been previously stored. For example, if the comparison results in deviation of 10% or less between the acquired portion of the contour Cpar and the stored contour Cpred, then the acquired portion of the contour Cpar will be identified as belonging to a previously stored contour. Otherwise, the acquired image 11A is repeatedly processed until the type of detergent is determined or identified as a detergent with average characteristics (i.e. with average chemico-physical properties).
- the comparison step 13 in case of comparison between the acquired roughness value Racq with a threshold roughness value Rth, comprises the step of assessing whether such acquired roughness value Racq is:
- the step of comparing the threshold value Rth with the acquired value Racq is carried out by assessing the deviation between the two imaginary lines, even when the door 7 has been opened.
- the method can detect whether there is a detergent D1, D2 or D3.in the dispenser 6.
- the method comprises a step 15 of providing a first capacity value Vin for the dispenser 6, said first value identifying the volume of the dispenser when it is empty.
- the method comprises a step of processing 17 the first captured image 11a to generate a second processed image 12B that defines a second capacity value for the dispenser 6, i.e. the value identifying the volume of the dispenser 6 when there is a detergent D1, D2 or D3 therein.
- the method includes a step of comparing (18) the first processed image 12A with the second processed image 12B to determine a residual capacity value Vres identifying the free volume of the dispenser 6.
- this comparison step 18 results in a residual capacity value Vres that is greater than 60% based on the first capacity value Vin, then there is no detergent in the dispenser 6.
- the result of the comparison step 18 may be combined with the processing step 12 to combine the information that can be obtained from the processed image 12A with the residual capacity value Vres to thereby obtain a higher degree of reliability in the identification of the type of detergent TD1, TD2, TD3.
- the method comprises a step 23 of notifying the type of detergent TD1, TD2, TD3 and/or the changes made to one or more of the parameters of the cleaning program P, through the user interface 9, to promptly inform the user of the changes that have been made.
- the method and the dishwashing machine 1 allow a change of the operating state of the machine to be notified through the user interface 9, allowing actions to be taken to restore the proper installation conditions of the object. This will reduce the need to wash part of the dishware and/or repeat the washing cycle, leading the water, detergent and power consumption.
