This invention relates to a jet regulator for a sanitary faucet and a sanitary faucet having such a jet regulator. Such sanitary faucets are used, in particular, to provide a liquid on demand at a sink or wash basin.
Sanitary faucets can have a jet regulator, through which the liquid can be dispensed as a laminar jet. Furthermore, such jet regulators can be designed in the manner of an aerator, through which air can be added to the liquid. However, dispensing the liquid as a laminar jet can result in high liquid consumption.
Therefore, the invention addresses the problem of solving at least a part of the issues described with reference to the prior art and, in particular, of providing a jet regulator for a sanitary faucet, which can reduce the liquid consumption of the liquid. Furthermore, a sanitary faucet having a jet regulator, which can be used to reduce the liquid consumption of the liquid, is to be specified.
These problems are solved by a jet regulator and a sanitary faucet having the features of the independent claims. Further advantageous embodiments of the invention are specified in the dependent claims. It will be appreciated that the features listed individually in the dependent claims may be combined in any technologically useful manner and define further embodiments of the invention. In addition, the features indicated in the claims are further specified and explained in the description, wherein further preferred embodiments of the invention are illustrated.
A jet regulator for a sanitary faucet, having at least the features listed below, contributes to solving the problem:
The jet regulator can be used in particular for a sanitary faucet, which is used to provide a liquid, in particular water or mixed water, for instance at a tap, a sink and/or a wash basin. The mixed water can be mixed by the sanitary faucet or a mixing valve of the sanitary faucet, in particular from cold water having a cold-water temperature and hot water having a hot-water temperature. The cold-water temperature is in particular at most 25° C. (Centigrade), preferably 1° C. to 25° C., particularly preferably 5° C. to 20° C. and/or the hot-water temperature is in particular at most 90° C., preferably 25° C. to 90° C., particularly preferably 55° C. to 65° C. The mixing cartridge can be disposed at least in part in a faucet body of the sanitary faucet. Furthermore, an actuating element can be used to actuate the mixing valve, in particular for setting a mixed-water temperature of the mixed water and/or for dispensing the mixed water. The actuating element can, for instance, be designed in the form of a lever or rotating element.
The jet regulator may, for instance, be of the mousseur or aerator type and/or be used to dispense the liquid to an environment of the sanitary faucet. The jet regulator may be (substantially) cylindrical in shape and/or extend along a longitudinal axis. In particular, the jet regulator may have a length of 5 mm to 50 mm in parallel to the longitudinal axis and/or a diameter of 5 mm to 50 mm (in particular orthogonal to the longitudinal axis). Furthermore, the jet regulator may be at least partially made of metal and/or plastic. The jet regulator, for instance, can be designed in the manner of a plastic die-cast component. In addition, the jet regulator can be disposed in particular at the sanitary faucet, at a faucet body of the sanitary faucet, at an outlet of the sanitary faucet or at a shower head of the sanitary faucet. In particular, the jet regulator can be arranged at and/or at least partially in an outlet opening of the sanitary faucet.
The jet regulator has a first spray plate for dispensing the liquid as a laminar jet. For instance, the first spray plate may serve to unify, broaden, and/or slow the liquid exiting the first spray plate. The laminar jet is in particular a liquid jet having a (substantially) laminar flow. For this purpose, the spray plate can have a plurality of flow channels that extend in parallel to one another and/or to the longitudinal axis of the jet regulator. The flow channels can, for instance, be designed in the manner of a flow rectifier. Furthermore, the laminar jet may be a full jet or a standard jet. In particular, the laminar jet consists of one single liquid jet. In particular, the laminar jet is not a rain jet formed by a plurality of individual jets. Furthermore, the laminar jet may have an annular cross-section, in particular orthogonal to the longitudinal axis. For this purpose, the first spray plate may have an annular first liquid dispensing port. For instance, it can have an inner diameter of 1 mm (millimeter) to 15 mm and/or an outer diameter of 5 mm to 40 mm. In particular, the first spray plate is designed such that the liquid exits the first spray plate at a liquid pressure of 3 bar at a first liquid volume of 7 l/min (liters per minute) to 11 l/min, preferably 8.5 l/min to 9.5 l/min, particularly preferably (substantially) 9 l/min.
Furthermore, the jet regulator has a second spray plate for dispensing the liquid as a mist jet. To this end, the second spray plate may, in particular, atomize the liquid as it is dispensed and/or dispense it in a plurality of droplets, which may, for instance, have an average droplet diameter of 10 μm (micrometers) to 500 μm. In particular, all of the liquid delivered via the second spray plate can be delivered as a mist jet. In particular, the second spray plate is designed such that the liquid exits the second spray plate at a liquid pressure of 3 bar at a second liquid volume of 0.1 l/min to 0.6 l/min (liters per minute). If a (full) laminar jet is not required, dispensing the liquid as a mist jet can reduce the liquid consumption of the liquid.
The first spray plate may at least partially encompass the second spray plate in an annular manner. For instance, the second spray plate can be at least partially disposed within the first spray plate. For this purpose, the first spray plate can, for instance, have a mount for the second spray plate. The first spray plate and the second spray plate are arranged in particular coaxially to each other.
The second spray plate can be designed in the manner of a nozzle. In particular, the second spray plate has a single nozzle. The nozzle may be at least partially funnel-shaped and/or taper toward a nozzle opening or a second liquid dispensing opening of the second spray plate. The nozzle orifice or second liquid dispensing orifice may have (in particular orthogonal to the longitudinal axis of the jet regulator or second spray plate) a circular cross-section and/or a diameter (in particular orthogonal to the longitudinal axis of the jet regulator or second spray plate) of 10 μm (micrometer) to 500 μm.
The second spray plate may include a nozzle element and a feed element. This can mean, for instance, that the spray plate is (only) formed from two parts. In particular, the nozzle is formed in the nozzle element. The feed element may at least partially form and/or delimit an inlet chamber of the second spray plate. The liquid in particular can be fed to the second spray plate via the inlet chamber.
The nozzle element and the feed element may be inserted into the first spray plate from opposite directions. In particular, the nozzle element and the feed element may be inserted into the first spray plate in parallel to the longitudinal axis of the jet regulator.
In accordance with another aspect, a sanitary faucet is also proposed, comprising at least the components listed below:
The faucet body can at least partially be made of plastic and/or metal, such as brass or a zinc alloy. Further, the faucet body can be attached to a support, such as a countertop, the sink, or the wash basin. In addition, the faucet body can have a (protruding or branching) outlet that is rigidly or movably connected to the faucet body. The outlet can be formed to be at least partially tubular. In addition, the outlet can be at least partially formed by a helical spring. Further, the faucet body and/or outlet may have a decorative outer surface. The outlet may have an opening that, in particular, connects an interior of the outlet to an environment of the sanitary faucet. A hose can extend through the outlet, through which the liquid can be routed to the jet regulator.
The liquid can be routed to a second spray plate of the jet regulator via an inlet channel that opens into an inlet chamber of the second spray plate at an angle to a longitudinal axis of the second spray plate. As a result, the liquid can be routed to the second spray plate or the nozzle, in particular as a eddy current or swirled.
The sanitary faucet may include a valve for feeding liquid to either a first spray plate of the jet regulator or a second spray plate of the jet regulator. The valve can be designed in particular in the manner of a 2-way valve.
The sanitary faucet may have a changeover element for actuating the valve. In particular, the changeover element can also be designed in the manner of push button or a toggle element.
The changeover element can be arranged at the faucet body or a shower head of the sanitary faucet. The shower head can be designed in particular in the manner of a hand shower. Further, the changeover element may be at least partially disposed at an outer surface of the sanitary faucet, the faucet body, the outlet, or the shower head of the sanitary faucet. In this way, the changeover element can be actuated or contacted by a user of the sanitary faucet.
