A washing machine includes a cabinet; an outer basket in the cabinet and configured to accommodate wash water; an inner basket in the outer basket and configured to accommodate laundry; a water supply valve unit in the cabinet and connected to an external water supply source to receive the wash water; and a micro-bubble generator configured to receive the wash water from the water supply valve unit, generate micro-bubbles, and supply the micro-bubbles. The micro-bubble generator includes a dissolving unit configured to mix or dissolve gas into the wash water. The dissolving unit includes a dissolving body having an open upper end and a dissolved water drain portion at one side, discharging wash water in which gas is mixed or dissolved; a cap fastened to the open upper end of the dissolving body and having a water supply line connection unit configured to introduce wash water and a supply hole configured to introduce gas into a dissolution space; and an air supply unit fastened to the cap at the supply hole.

Apparatus for providing a laundry product to a wash load based on user input, comprising a dosing unit (2) for placing in a washing machine drum and a dispensing device (1) having a dispensing area (3), a nozzle (4) and a plurality of reservoir cartridges (6a, 6b, 6c) containing various laundry products that are combined by a user and which are dispensed into the dosing unit (2) by said nozzle (4) as soon as said dosing unit (2) is placed in the dispensing area (3) located underneath the nozzle (4).

A turbine system includes a foam generating assembly having an in situ foam generating device at least partially positioned within the fluid passageway of the turbine engine, such that the in situ foam generating device is configured to generate foam within the fluid passageway of the turbine engine.

A method and apparatus for obtaining a product chemistry from a product and a fluid is provided. A product is housed within a dispenser. A fluid is introduced through a manifold diffuse member having a plurality of ports. A cover is positioned adjacent the manifold diffuse member and includes a plurality of ports. The cover is able to be adjusted, for example, by rotating the cover, to align and un-align the manifold diffuse ports and the cover ports. This adjustment controls the flow characteristics of the fluid through the manifold diffuse member and cover to control the characteristics of the fluid in contact with the product. The adjustment of the cover to control the flow will provide a generally consistent concentration and erosion rate based upon known relationships between a characteristic of the fluid and the flow of the fluid in relation to the product.

The present invention relates to hydrogencarbonate water and a cleaning method using the hydrogencarbonate water. Provided are hydrogencarbonate water obtained by dissolving carbon dioxide in hydrogen water having a dissolved hydrogen concentration of 0.1 ppm to 2.0 ppm; and a cleaning method comprising cleaning a substrate by immersing the substrate in the hydrogencarbonate water, or spraying the hydrogencarbonate water to the substrate.

An apparatus to generate soapsuds is described. The apparatus features a character lid, a lid attachment member, a holding member, an agitator, and a soap dispenser. The holding member includes a chamber portion sized to retain one or more soap tablets. The chamber portion has an opening, a closed end including an outlet, and lateral surfaces extending between the opening and the closed end. The agitator is rotationally coupled to the holding member and positioned under the outlet of the holding member. The soap dispenser includes a housing that encapsulates the agitator residing within a lower quadrant of the interior area of the housing. The housing includes apertures formed within the closed end to allow for soapsuds and soapy water passage through the opening and the outlet of the holding member, which causes the agitator to mix the soapy water residing within the interior area to generate soapsuds.

A valvular conduit, preferably a Tesla valvular conduit, in which a plug member is coaxially received within a bore in a sleeve member and in which passageways are defined between the plug member and the sleeve member within interior walls configured to permit mixing of fluid flowing through the passageways in at least one direction, preferably, the relatively free passage of fluid through the passageways upstream but increased the resistance to downstream flow of the fluid through each passageway.

A method and apparatus for obtaining a product chemistry from a solid block is provided. The product is housed within a dispenser, which utilizes a liquid and a gas to erode the block and produce a concentrate solution. The liquid and gas characteristics can be adjusted in the field to achieve a predetermined concentrate level in the solution. The introduction of air into the dispenser saves water, while producing higher concentrate levels.

A flow-rate regulator device for controlling a flow rate of a liquid includes a first flow-rate regulator component positioned on an upstream side of a liquid line, and a second flow-rate regulator component positioned on a downstream side of the liquid line and connected in series to the first flow-rate regulator component. The first flow-rate regulator component adjusts a degree of opening such that a flow rate of liquid flowing through the liquid line is set a specified number of times greater than a target flow rate when the second flow-rate regulator component has a full opening, and the second flow-rate regulator component adjusts a degree of opening such that the flow rate of the liquid flowing through the liquid line is to be at the target flow rate when the first flow-rate regulator component is adjusted to have the degree of opening.

A foam generating device for a high-pressure water gun has a supporting body (14) defining part of a conduit (2), which extends along an axis (3) and has a mixing chamber (7) communicating with a lower inlet, and subject, in use, to a vacuum to aspirate a liquid from said lower inlet; the device has a first sleeve (17) which is fitted around one end of the supporting body (14), is axially fixed, is rotatable and is provided with an end portion carrying a nozzle (40); such a nozzle (40) defines the outlet (5) of the conduit and is adjustable so as to vary the outgoing flow type between a fan-like jet and a solid stream jet; the device has, in addition, a second sleeve (44) which is coupled to the first sleeve (17) in a fixed axial position and in a rotatable manner and is provided with cams (49) to adjust the nozzle (40) in response to a rotation of the second sleeve (44) with respect to the first sleeve (41).
