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.

A dishwasher includes a tub, a spray arm, a sump, a pump body, the pump body including a partition between first and second chambers, a communication hole in the partition that communicates with the first and second chambers, a pump flow path that connects the sump to the first chamber, an arm flow path that connects the spray arm to the second chamber, an impeller in the second chamber, a heating unit to heat water in the first chamber, a steam flow path that connects the first chamber to the tub, a connection flow path that connects the steam flow path to the arm flow path, and a flow path valve configured to close the steam flow path based on water being supplied to the connection flow path, and to open the steam flow path based on a lack of water being supplied to the connection flow path.

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.

The present invention is a fiber self-cleaning system. The fiber self-cleaning system of the present invention includes interlocking mats containing bores for receiving cleaning tubes, cleaning tubes for mounting with the mat bores having an open top, beveled interior chamber and at least one transverse side opening, fiber groups mounted within the beveled interior chamber of the cleaning tubes, a water and vacuum line operatively connected to the cleaning tubes to introduce water, chemicals and air to the fiber groups or to apply a vacuum force to the fiber groups, and a pump operatively connected to the cleaning tubes to introduce or suction out water, chemicals and dirt from the fiber groups.

A surface treatment machine, comprising a frame configured to translate with respect to a surface to treat, a surface treatment element connected to said frame and configured to treat with liquid a surface, a reservoir connected to the frame arranged to provide liquid to the surface treatment element through a delivery mouth; an adjustment element arranged to feed adjustably the liquid supplied from the reservoir to the delivery mouth. It is then provided a sensor configured to measure the speed of the frame with respect to the surface to treat. A control unit receives from the sensor a signal proportional to a speed for adjusting the adjustment element responsive to this value, in order to deliver the liquid with optimization of the flow-rate. It is possible then to maximize the range of the machine, and to optimize the working time of the operator.

Methods and systems for cleaning floor surfaces are provided. In various embodiments, floor cleaning devices comprise enhanced cleaning and disinfecting capabilities. A clean fluid storage tank and a spent fluid storage tank are provided on-board the device. Means for creating cavitation bubbles to enhance cleaning are contemplated. Additionally, chemical agents and systems are contemplated for sanitizing surfaces as well as fluid that is captured or recaptured by the device.

The present invention relates to a pump and a dishwasher including the same. The pump of the present invention includes a housing having a cylindrical shape to contain water; an rotatable impeller to discharge the water in the housing to an external; a heater cover to form a bottom surface of the housing; a heater plate joined to a lower side of the heater cover; and a heater joined to a lower side of the heater plate to heat the heater plate. The heater is not in directly contact with the heater cover.

The present invention discloses a robot that moves on a surface. The robot includes a casing, a moving unit coupled to the casing, and a suction disk coupled to the casing. The casing, the suction disk and the surface are configured to form an airtight space. The robot further includes an air extraction module and a spray module. The air extraction module is disposed in the casing and is in communication with the airtight space, and the air extraction module is configured to generate a negative pressure in the airtight space. The spray module is coupled to the casing and configured to spray a liquid onto the surface.

A cleaning product including a spray dispenser and a cleaning composition suitable for spraying and foaming, the composition housed in the spray dispenser and includes: i) from about 5 to about 15% by weight of the composition of a surfactant system; and ii) a specific glycol ether solvent, the surfactant system and the glycol ether solvent are in a weight ratio of from about 5:1 to about 1:1.

A nozzle of a cleaner includes a nozzle body, a rotation cleaning part having a rotation plate to which a rag is attached, a driving device provided in the nozzle body, a water tank, a water supply passage, and a water adjuster of which at least a portion is mounted on the nozzle body at a rear side thereof so as to be exposed to a rear surface or a top surface of the nozzle body. A user standing on the same floor surface as the nozzle body may manipulate the water adjuster by using his or her foot. The water adjuster may be configured to adjust an on/off operation and a rotation speed (e.g., rpm) of the pump motor.
