An artificial intelligence dishwasher including a dish rack on which dishes are arranged, a spray nozzle configured to spray washing water toward the dishes, a washing pump configured to feed washing water stored in a sump to the spray nozzle, a washing motor configured to drive the washing pump, a camera configured to capture the dish rack to obtain a dish arrangement image, and a processor configured to provide the dish arrangement image to a dish recognition model to obtain dish information included in the dish arrangement image, determine a washing cycle for the dishes based on the dish information, and control driving of the washing motor according to the determined washing cycle is provided. A dishwashing method is also provided.

Methods of dishwashing to remove soils are disclosed, including a first detergent wash step, wherein the detergent is substantially-free of water conditioning agents including polycarboxylic acid polymers and phosphonates, followed by a second step of rinsing under high temperature with a water conditioning agent, namely polycarboxylic acid polymers. The methods result in little to no precipitation forming on the treated ware due to the treating of the hard water before it contacts the alkalinity source which prevents precipitation and/or flocculation from occurring.

A dishwasher includes: a spray module which sprays washing water toward dishes; a sump which supplies washing water to the spray module; a pump which pumps washing water stored in the sump to the spray module; and an air jet generator which receives a part of washing water pumped from the pump to form an air bubble in washing water and discharges the air bubble to the sump, wherein the air jet generator comprises: a decompression portion which decreases a pressure of washing water; an air suction portion which is opened to allow air to flow into the decompression portion; a pressing portion which increases pressure so as to crush the air introduced from the air suction portion; and an air tap which has a plurality of holes configured to crush the air contained in washing water that passed through the pressing portion.

Example intelligent dishwashing systems and methods are described. In one implementation, a system includes an imaging system configured to capture at least one image of an article of dishware. A processing system analyzes the at least one image to determine a presence and a location of a stain on the article of dishware. Responsive to determining the presence of a stain, a cleaning system is configured to clean the location of the stain on the article of dishware.

A dishwasher and method for treating dishes according to a cycle of operation, the dishwasher comprising a tub at least partially defining a treating chamber and a dish rack movably received within the treating chamber. The dishwasher configured for receiving dishes for treatment during the cycle of operation, and moveable relative to the tub. A sprayer located within the treating chamber, configured to emit spray into the dish rack. A deflector coupled to the sprayer.

Phosphorus-free detergent compositions are provided. Detergent compositions including an aminocarboxylate, water conditioning agent, source of alkalinity and water beneficially do not require the use of additional surfactants and/or polymers to provide suitable detergency and prevent scale build-up on treated surfaces. The detergent compositions are used with a sanitizer to employ the phosphorus-free detergent compositions for use as low temperature ware wash detergents that beneficially reduce scale build-up. Methods of employing the phosphorus-free detergent compositions are also provided.

Disclosed a dishwasher, wherein dishes placed on a conveyor are washed, rinsed, and dried while being sequentially conveyed to a washing chamber, a rinsing chamber, and a drying chamber, the dishwasher including: a heat exchanger allowing hot air to be supplied to the drying chamber by heat exchange; a wash water tank in which water supplied to the washing chamber or the rinsing chamber is stored; and a spray device spraying water supplied from the wash water tank onto the dishes placed on the conveyor, whereby it is possible to save energy by providing a single heat exchanger to preheat wash water and rinse water and supply hot air to the drying chamber, and to improve circulation of wash water by a filtering device applied to a structure for reusing wash water, thereby improving sanitation of dishwashing.

A dish washing machine including a cabinet having a frame defining a periphery of the dish washing machine, with the cabinet having a top, a front, a rear and a pair of sides. A dish washing area is located within the cabinet and includes a nozzle for spraying a liquid onto dishes in the dish washing area. The front of the cabinet has a door for allowing access into the dish washing area. A top wash basin is on the top of the cabinet, with the top wash basin including a spout for water and a sink for accepting liquid therein. The cabinet also can include a rinse detergent tank and a wash detergent tank, wherein a rinse detergent can be added to the rinse detergent tank and a wash detergent can be added to the wash detergent tank while the wash washing machine is activated.
