A washing machine that 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, configured to receive 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 to a washing space. The micro-bubble generator includes a dissolving unit configured to mix or dissolve gas into the wash water from the water supply valve unit. The dissolving unit includes: a water supply line connection connected indirectly to the water supply valve unit, configured to introduce the wash water; a supply hole providing a path in which gas is introduced into a dissolution space; and a dissolved water drain portion discharging the wash water in which gas is mixed or dissolved.

A device for automatically and selectively dispensing multiple additives into a base liquid is disclosed, where each additive is dispensed by a control mechanism that effectively shuts off and is self-cleaning. In one embodiment, each additive is provided through a channel comprising a tube, a check disk, and a fulcrum. When the pressure of a particular additive increases above a threshold, a flexure is created in the check disk, which causes an opening that allows the additive to enter a main channel where it is mixed with a base liquid. When the pressure of the liquid additive is decreased below the threshold, the check disk reverts to its original form and the additive is no longer dispensed into the base liquid. Thereafter, the base liquid cleanses the mechanism.

A vehicular cleaning system performs cleaning to remove foreign matter attached to a cleaning target in a vehicle. The vehicular cleaning system includes: an air pump driven to generate an air spray; a washer pump driven to supply a washing solution; a spray nozzle which blows an air-liquid mixed fluid, obtained by mixing the air spray and the washing solution, onto the cleaning target; a washing solution storage unit configured to store the washing solution supplied from the washer pump, and to be capable of discharging the stored washing solution when the washing solution is to be mixed with the air spray; and a mixing and outputting unit configured to blow the air-liquid mixed fluid, obtained by mixing the air spray and the washing solution introduced from the washing solution storage unit, from the spray nozzle toward the cleaning target.

Conventional ozone water is still insufficient in the removal rate and cleaning ability of resist required in today's semiconductor manufacturing field, and it does not fully meet the expectation of further improvement in the effects of sterilization, deodorization, and cleaning in the fields such as cleaning of foodstuffs, cleaning of process equipment and tools, and cleaning of fingers, as well as in the fields such as deodorization, sterilization, and preservation of freshness of foodstuffs. The above problem can be solved by defining the values of a plurality of specific production parameters in the production of ozone water into specific ranges.

Provided is a washing machine capable of improving solubility of a powder detergent that remains without having been dissolved in mixing water contained in a tub. The washing machine includes a cabinet having a detergent supplier, a tub arranged in the cabinet to be connected to the detergent supplier and containing mixing water in which washing water supplied to the detergent supplier and a powder detergent are mixed, a drum rotatably installed in the tub, a circulation hose connecting between the tub and the drum for the mixing water contained in a lower portion of the tub to be circulated, a detergent dissolution device generating vortex current in mixing water circulated through the circulation hose to improve solubility of the powder detergent, and a circulation pump arranged in the circulation hose and configured to repeatedly supply and discharge mixing water to and from the detergent dissolution device through on/off controlling.

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.

Provided is a UFB-containing liquid production apparatus that can efficiently produce a UFB-containing liquid with a UFB generation unit. The UFB-containing liquid production apparatus includes: a gas dissolution unit that produces a gas-dissolved liquid by dissolving a gas into a liquid supplied from a liquid supply unit; a UFB generation unit that generates UFBs in the flowing-in gas-dissolved liquid; and a circulation path that supplies the gas-dissolved liquid to the UFB generation unit and supplies a UFB-containing liquid produced by the UFB generation unit to the liquid supply unit. In the circulation path, there is provided a micro-bubble reduction unit that reduces an amount of micro-bubbles contained in the gas-dissolved liquid to flow into the UFB generation unit.

An improved flow rate metering device that provides for the mixing and dispensing of two or more fluids to form final mixture, for example, for automatic washing of cars and trucks. More specifically, the invention is a system that mixes and ejects chemicals, creating a very precise mixture of one or more chemicals with a dilutant, such as water. The device also has the capability of monitoring an entire chemical dilution and release system, comprising multiple chemicals, and using software to document past and current usage rates, along with predicting future usage rates based upon both past usage rates and environmental conditions.
