Problems solved by technology
[0022] The presence of foam inside the washing zone of the dishwasher can lead to increased noise during the operation of the washer pump
[0023] In addition, the presence of foam may alter the normal performance of the cleaning cycle, which leads to poor cleaning performance
[0024] Furthermore, in the event of foam formation in the wash zone, there is a specific risk of detergent residues on the dishes at the end of the wash
[0025] It should be emphasized that in the case of excessive foam formation inside the washing zone, problems may arise in the operation of the dishwasher, with the consequent risk of product failure

Embodiment Construction
[0044] Individual features described with reference to a specific embodiment must be considered as dependent features and / or interchangeable with other features described with reference to other embodiments, even if not explicitly highlighted.
[0045] Reference attached image 3 , 4and 5, 1 denote a dishwasher of the type built eg into a kitchen unit without finishing panels for a better understanding of the internal volume.
[0046] Such a dishwasher 1 comprises a washing zone 2 and a door 3 which can be associated with the washing zone 2 when closed.
[0047] The dishwasher 1 identifies a base 1A, which is generally dedicated to housing the mechanisms / devices required for the main operation of the dishwasher 1 .
[0048] The washing zone 2 defines a volume in which dishes S are arranged.
[0049] In particular, the cleaning zone 2 is defined by a plurality of walls, such as a base wall 2A, side walls 2B and 2C, a top 2D and a bottom wall 2E, and identifies an upper part ...

A dishwashing machine, and a method and system for automatically evaluating the presence of foam in the same are provided. The method comprises the steps of: acquiring a first digital image representative of a first condition of a washing fluid collection zone of the dishwashing machine; digitally processing the first digital image so as to obtain a first processed image which identifies the valueof a first volume of fluid contained in the washing fluid collection zone; acquiring a second digital image representative of a second condition of the washing fluid collection zone after a predefined time interval from the performance of the step of acquiring a first digital image; digitally processing the second digital image so as to obtain a second processed image that identifies a value of asecond volume of fluid contained in the washing fluid collection zone; comparing the value of the first volume of fluid with the value of the second volume of fluid for calculating a value of fluid volume variation; generating a foam presence signal indicative of the presence of foam in the washing fluid collection zone, when the value of fluid volume variation exceeds a predefined threshold value; modifying the cleaning parameters of the cleaning program of the dishwashing machine when the foam presence signal is generated.
Description
technical field [0001] The present description relates to a method for automatically evaluating the presence of foam in a dishwasher. [0002] The present description also relates to a dishwasher configured to implement a method for automatically evaluating the presence of foam in a dishwasher. [0003] The present description also relates to a system comprising a dishwasher and a portable device that can be held by a user and configured to implement a method for automatically evaluating the presence of foam in a dishwasher. Background technique [0004] Dishwashers are known in the prior art, which are provided with optical devices such as ordinary cameras, television cameras or video cameras, which are arranged in a fixed or movable position relative to the washing tank, To check the weight of the tableware or the cleanliness of the tableware. [0005] For example, documents WO 2016008699 A1 and US 2012 / 0138092 A1 exemplify such a dishwasher. Furthermore, document US 20...
