Abstract
Description
- My present invention relates to a cartridge for a single-lever mixing faucet of the type in which the control of the flow and of the water temperature is effected by the movement of one disk relative to another by a lever pivotal in a cartridge housing in which the disks are contained.
- Cartridge-type water faucets which have a faucet body capable of receiving the cartridge and whereby the hot and cold water lines are connected to the outlet through the cartridge are increasing in utilization throughout the world.
- It is also known to provide contactless electrically-controlled faucets which have been widely used in public facilities. However, if the electric current supply to such faucets fails or electrical components like electric valves fail, water cannot flow from the faucet.
- It is, therefore, the principal object of the present invention to provide an improved cartridge for a single-lever mixing faucet of the aforedescribed type which enables water supply even in the case of a failure of the electrical component or of the supply power.
- Another object of this invention is to provide a more versatile cartridge for a faucet whereby drawbacks of earlier systems are avoided.
- These objects are attained, in accordance with the invention by providing within the cartridge a second valve, i.e. a valve in addition to that formed by the relatively slidable disk and in an outlet passage of this cartridge or the first valve thereof. More particularly, the cartridge for a single-lever mixing faucet according to the invention can comprise:
- a faucet-cartridge housing;
- a nonshiftable inlet/outlet disk in the housing communicating with hot and cold water inlets and an outlet;
- a shiftable control disk in the housing juxtaposed with the inlet/outlet disk for selectively connecting the inlets with the outlet;
- a lever pivotally mounted in the housing and operatively connected with the control disk for displacing the control disk; and
- an electrically operated valve within the housing in the outlet.
- With the control afforded by the present invention, the electromagnetically operated valve can be triggered to enable and disable the flow of any response to the project to the faucet, e.g. the hand of the user, while manual actuation is also possible. The manual actuation can enable control of the volumetric flow rate so that the flow itself can be independent of the electric valve. The manual operation allows supply of the water even in the case of a failure of the proximity switch or other means for sensing the presence of the user.
- The manual actuation, in addition, allows complete blockage of the flow so that for cleaning of the faucet or the basin or sink, undesired openings of the electrical valve by the proximity or contactless sensor will have no effect.
- It is especially advantageous to form the inlet/outlet disk with a second outlet opening form which water passes through the system, the second passage opening directly into the outlet. The second valve should be advantageously an electromagnetic membrane valve.
- The above and other objects, features, and advantages will become more readily apparent from the following description, reference being made to the accompanying drawing in which:
- FIG. 1 is an axial section through a cartridge provided with an electromagnetic valve according to the invention;
- FIG. 2 is a plan view of the lower housing region of the cartridge;
- FIG. 3 is an axial section through the lower housing region;
- FIG. 4 is a plan view of the nonmovable inlet/outlet disk;
- FIG. 5 is a section taken along the line V-V of FIG. 4;
- FIG. 6 is a plan view of the movable disk;
- FIG. 7 is a section taken along the line VII-VII of FIG. 6;
- FIG. 8 is an axial section through the cartridge; and
- FIG. 9 is a bottom view of the lower housing region as represented in FIG. 3.
- The cartridge shown in the drawing for the single-handle mixing faucet is received in a housing of the faucet which has not been shown and which is provided with a hot and cold water fitting and a spout or other outlet connected to the outlet of the cartridge. The cartridge can be replaced as a unit and eliminates the need to change washers, thereby renewing the interior of the faucet as a unit.
- The cartridge itself comprises an
upper housing portion 20 and alower housing portion 21. In the underside of the upper housing portion, an inlet/outlet disk is fixedly mounted and has an inlet opening EW for the hot water, an inlet opening EK for the cold water, an outlet opening AH for the mixed water and under manual control and a mixed water outlet opening AE under electrical control. - Above the inlet/
outlet disk 9 is a horizontallymovable control disk 10 with a downwardlyopen mixing chamber 22 which, depending upon the position of thedisk 10 connects the opening of the inlet/outlet disk 9 with one another so that cold water and/or warm water and usually a mixture of the two can flow at greater or lesser flow rates to the outlet opening AH or the outlet opening AE as selected by thelever 14 which is pivotally mounted in the cartridge and engages thecontrol disk 10. Themanual lever 14 has the following positions: - 1. The lever down: no water discharged possible (sleep function). For cleaning of the faucet or of the basin or sink.
- 2. Lever14 in an intermediate position (automatic mode). Flow and temperature determined by the position of the lever. On and off determined by the electrically-operated valve.
- 3. Lever14 up: water flows continuously. Used, for example, in the case of a failure of the supply current to the electric valve or a failure of the electric valve itself.
- The electrically-controlled membrane valve6 is located in a lower housing portion of the cartridge and has a membrane movable from a closed position into an open position by an
electromagnet coil 2. When the valve 6 is electrically energized, it opens and the mixed water flows from the outlet opening AE via theoutlet passage 8 to thevalve outlet 7 into thecartridge outlet 18. The opening AH can be closed by a middle region M of thecontrol disk 10. - If the
valve 7 is not energized and thus closed, the outlet opening AH can be opened by movement of thedisk 10 and the mixed water can bypass the valve 6 to theoutlet 18. The flow is controlled then exclusively by the position of thelever 14 and the electrical valve is not effective. With the application of an electrical pulse to thecoil 2, thecontrol piston 4 is so positioned that flow is permitted from the inlet it to the valve 6 through themembrane 5 and out through theoutlet 7 of the valve 6 from the control unit. By means of thedisk 1, which is preferably a magnet, the position of thecontrol piston 4 can be set independently of the electrical signal. When the electrical signal is applied, therefore, the position of thepiston 4 can be altered so that flow through theoutlet 7 is permitted or prevented. - The geometry of the
disks disks toggle lever 14 at which flow will be blocked at theoutlet 18 or permitted. - A
bushing 11 is braced against thedisk 10 and entrains the latter, thebushing 11 being pivotally connected at 17 to thelever 14 which, in turn, is pivotally connected at 15 to aring 12 fixed in theupper housing portion 20 and surrounded by acap 16 surmounted by aring 19. - The electrical valve6 can be connected to a proximity detector responsive to the introduction of the hands of the user into the region of the faucet, e.g. below the spout.
