A dishwasher includes a tub at least partially defining a treating chamber, a rotatable spray arm comprising an outlet, and a liquid supply conduit fluidly coupled to the spray arm. A pump can be fluidly coupled to the liquid supply conduit and operated to flow liquid through an aperture in the liquid supply conduit and through the outlet in the rotatable spray arm.

Disclosed is a dishwasher including: a washing tub in which a rack on which a washing object is seated is disposed; a spray tube which has a rotation shaft extending in a direction intersecting upper and lower shafts, and has a spray nozzle disposed therein to eject flowing washing water in a direction intersecting the rotation shaft; a power applying device that generates power; and a driving module connected to the spray tube so that the power generated by the power applying device is transmitted to the spray tube, wherein the driving module includes: a rotation body which is connected to the power applying device; a pendulum body extending from the spray tube in a direction intersecting the rotation shaft; and a conversion link connected to the rotation body and the pendulum body to convert rotational motion of the rotation body into pendulum motion of the pendulum body.

A dishwasher and method of operating a dishwasher according to a cycle of operation are described herein. The dishwasher includes a tub at least partially defining a treating chamber, a rotatable spray arm comprising a nozzle outlet, and a liquid supply conduit fluidly coupled to the spray arm. A pump can be fluidly coupled to the liquid supply conduit and operated to flow liquid through an aperture in the liquid supply conduit.

A spray arm, a water pumping mechanism and a cleaning machine thereof are disclosed in the present invention. The spray arm comprises a body (1;1) and a top plate (2;2). An air collection chamber (20;20) is defined between the top plate (2;2) and the top surface (1a; 1a) of the body (1;1), a plurality of water spray holes (13) is arranged in the air collection chamber (20;20), the top plate (2;2) has a plurality of spray openings (21) each corresponding to one water spray hole (13), and a gap (100) is formed between a top end of each water spray hole (13) and a bottom end of the corresponding spray opening (21). According to the Venturi effect, the air in the air collection chamber can be sucked into the spout through the gap when the water flow passes through the water spray hole and is jetted out through the spray opening, such that bubbles are entrained in the jet flow; the bubbles are broken on surfaces of dishes or fruits and vegetables, which can improve dirt stripping force, and improve the washing effect.

A dishwasher, in particular a domestic dishwasher, includes a control device configured to perform a number of washing programs for washing items to be washed, and an input means configured to register a user input for shortening a running selected washing program. The control device is configured to adjust the running selected washing program as a function of a registered user input in such a manner that a remaining washing time of an adjusted selected washing program is shortened compared with a regular remaining washing time of the running selected washing program.

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 dishwasher includes a reservoir for storing washing fluid, and a control device configured for calling up at least one dishwashing program for controlling a washing cycle for washing items to be washed in a washing chamber and at least one preheating program for controlling a preheating cycle for preheating washing fluid for a washing cycle separately from each other. The preheating cycle includes a heating phase during which washing fluid is circulated and the circulated washing fluid is heated. The preheating cycle has downstream of the heating phase a pumping phase during which previously circulated and heated washing fluid is pumped into the reservoir.

The preset disclosure relates to a dishwasher. The dishwasher includes: a tub defining a washing space; a sump disposed below the tub and configured to store wash water therein; a pump configured to supply the wash water stored in the sump to the tub; and a spray arm configured to supply wash water flowing from the pump to the washing space. The spray arm includes: a spray blade configured to spray wash water into the washing space; a bubble generator having therein a bubble generation flow path of a venturi tube shape and configured to supply wash water containing a microbubble to the washing space; and a hub configured to supply wash water discharged from the pump to the spray blade or the bubble generator. The spray arm sprays wash water through the spray blade while simultaneously generating a microbubble through the bubble generator.

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.
