Abstract: A refrigerator includes a cabinet defining a refrigerating chamber and a freezing chamber, an ice making device and an ice making water supply device. A variable temperature drawer is disposed in lower part of the refrigerating chamber. The ice making water supply device includes a water tank disposed above the variable temperature drawer, a water pump connected with the water tank, and a water pipe connected with the water tank and the ice making device for introducing the water in the water tank into the ice making device. With the refrigerator according to embodiments, the water quality is ensured and the preservation effect is improved.

Abstract: A stream redirecting device for a sprinkler includes a shell-shaped body having a generally semi-circular shape in plan, with opposite inlet and outlet side edges. The body extends outwardly and upwardly from a base at a lower end and then upwardly and inwardly to a distal, arcuate edge at an upper end. An inside surface of the shell-shaped body is formed with a plurality of grooves between the inlet side edge and the outlet side edge, extending in a generally radial direction with entry ends adjacent the base and exit ends at the distal, arcuate edge. The grooves are formed with circumferential exit angles that vary substantially uniformly in opposite directions from a center one of the plurality of grooves to first and last of the plurality of grooves at the opposite inlet and outlet side edges, respectively.

Abstract: A pendant sprinkler preferably includes a body having an inner surface defining a passageway. The passageway includes an inlet and an outlet spaced apart along the longitudinal axis and defines a K-factor of about 5. The sprinkler also includes a closure assembly adjacent the outlet to occlude the outlet and a thermally responsive support means for maintaining the closure assembly adjacent the outlet. Also provided are means for distributing a flow of fluid over a protection area ranging from about 144 square feet to about 400 square feet, the fluid distribution having a density of at least 0.05 gallons per minute per square foot (0.05 gpm/ft2) so as to define a range of minimum operating pressures ranging from about seven pounds per square inch to about seventeen pounds per square inch (7-17 psi.) and a range of minimum operating fluid flows ranging from about thirteen gallons per minute to about twenty gallons per minute (13-20 gpm.).

Abstract: A self-governing spray apparatus for irrigation or cleaning purposes is provided. A spray nozzle at the end of a moment arm and substantially perpendicular to an axis of rotation creates a reaction torque to distribute a spray by spinning. A hinged member thrust into the spray pattern a centrifugal force caused by the spin deflects a portion of the spray and results in a braking action. An equilibrium angular speed is thereby reached by a self-correcting mechanism.

Abstract: A spray head with improved distributor body for a high pressure spray cleaning apparatus is provided. The spray head is carried on the end of a hand held wand with control valves to separately regulate flow through a pair of fluid circuits, the spray head having a nozzle that sprays heated water in a fan-like pattern against a deflecting edge of a distributor body. Cleaning chemicals are forced through an aperture into the fan-like pattern prior to its striking the deflecting edge to be intimately mixed with the heated water to produce a mixture that strikes the deflecting edge and is deflected therefrom in a highly concentrated form at a high velocity. An elbow guard provides improved protection for the chemical cleaning fluid flow line where it connects to the spray head. Also disclosed is a spray head that allows for the separate application of fluids delivered from separate supply sources.

Abstract: A multifunctional sprinkler structure comprises a water motor having an outlet seat and a top cover mounted to a top-end side, and two adjusting seats and a water supply seat assembled onto a bottom-end side. The bottom-end side of the water motor has a guide groove with a restrictive hole for the extension of a switch shaft there-through. The outlet seat has a water-discharge chamber with multiple barriers extending thereon corresponding to an impeller of the water motor, and an oblique-extending central guide port matching to a spray nozzle having multiple water-guiding ribs obliquely extending towards the same direction therein. Therefore, the barriers of the outlet seat and the water-guiding ribs of the spray nozzle are utilized to correspond to the direction of the water flow so that the water discharge can be easily switched to eject either in more direct and forceful column-like spray or in more expanding spray.

Abstract: The guide member (1) for a liquid jet (30) to be deflected allows a liquid (3) after flowing out of a container (2) to be deflected onto a target (5; 7) which is located below the container. The deflecting takes place by means of a shaped material plate (10; 10a, 10b) which is arranged ahead of an outlet opening (20) of the container and which reshapes and further conducts the jet (30) in such a manner that the liquid is conveyed to the target at a lower end (17) of the shaped material plate. At the location ahead of the outlet opening (20), where the liquid jet (30) is incident onto the shaped material plate (10), a first and a second piece of surface (11 and 12 respectively) of the material plate form a mouth region (13) in which the first piece of surface (11) deflects the liquid (3) transversely with respect to the vertical, whereas the second piece of surface (12) is provided as a catcher for squirts. The first piece of surface merges into a channel (14) in which the liquid is guided downwards.
