Definitions
- the invention relates to a sanitary fitting with an electrical actuating device which has at least one capacitive sensor with at least one actuating region, the actuating region having a carrier layer of an electrically insulating material and an at least partially electrically conductive sensor layer which is functionally connected to an electrical control unit.
- actuation / detection areas for capacitive sensors are used.
- the water temperature and / or the water volume flow of the water emerging from the sanitary fitting can be adjusted with the sensors. It can also be other functional parts of the sanitary fitting, such as bulbs, operated with the sensors.
- the actuation / detection areas must be at least partially made of electrically conductive material that has no galvanic connections with the outer surface of the sanitary fitting.
- the layer structure should not contain inclusions, especially air pockets, which would affect the sensor's sensitivity to operation.
- it is desirable that the sanitary fittings with the operation / detection areas have an attractive appearance.
- Object of the present invention is to provide a sanitary fitting of the type mentioned in such a way that the sensors also withstand strong particular mechanical loads and beyond the sanitary fitting has a visually appealing appearance.
- the sensor layer is disposed on the side facing away from an actuating side of the actuating region side of the carrier layer and is connected via an electrically conductive line layer to the control unit.
- the senor is protected against external influences electrically and mechanically by the carrier layer to the outside.
- the sensor layer preferably "snuggles" against the carrier layer, which has the advantage that a virtually air-free connection is created between the outer surface of the sensor and the sensor layer and the sensor thus has a high capacitive sensitivity, so that it is completely without touching the sensor layer
- the contacting of the sensor layer in the direction of the control unit takes place via the line layer.
- the sensor layer may be capacitively connected to the conductor layer. This has the advantage that the sensor layer, which is difficult to contact, is capacitively integrated and thus has at least one contactless, non-galvanic connection to the control unit.
- the sensor layer can be arranged directly on the carrier layer and the line layer on the side of the sensor layer facing away from the carrier layer, and the sensor layer can be galvanically separated from the line layer.
- the conductor layer is adapted to the contours of the sensor layer, so that an optimal capacitive transmission is made possible.
- the sensor layer and the line layer may form the plates of a capacitor, and the line layer may be galvanically connected to the control unit. In this way, the capacity can be factory set reproducible.
- a dielectric with a high dielectric constant in particular a gel or a highly flexible adhesive, can be arranged between the sensor layer and the conductor layer.
- This has the advantage that the proportion of air is kept relatively small because of their low dielectric constant, since at most a small air gap remains.
- Gel and adhesive as a dielectric have the advantage that no mechanical load emanates from them.
- the conductor layer can be made of brass, which is a very good electrical conductor and allows a good, in particular corrosion-resistant galvanic connection.
- the line layer may be galvanically connected to the sensor layer.
- the conductor layer in particular a transparent conductive glass coating
- the conductor layer can be arranged directly on the carrier layer and the sensor layer on the side of the conductor layer facing away from the carrier layer.
- a transparent conductor layer, in particular a transparent glass coating, for example ITO, on a transparent carrier layer makes it possible for the optionally metallically reflecting sensor layer to be visible from the actuating side, which positively influences the visual impression of the sanitary fitting.
- the sensor layer can be arranged directly on the line layer. This also allows secure contacting of the sensor layer.
- a transparent electrically conductive coating for glass or similar materials may be applied to the carrier layer made of glass or similar material, and galvanically connected to a conductive sensor layer deposited thereon.
- the support layer may be made of a durable material with a smooth surface for applying the sensor layer, in particular of glass, porcelain or plastic, in particular crystal clear plastic such as acrylic glass or polycarbonate, in an optically particularly attractive and very robust manner.
- the sensor layer can be an area coated with metal, in particular aluminum or silver. Evaporated surfaces also do not contribute thick and technically easy to realize a capacitor plate. Deposited metals are good conductors and allow good capacitive coupling. In addition, vapor deposition of the conductive layer of aluminum or silver onto the transparent carrier layer results in a visually appealing mirror-like layer
- the senor layer may be coated on its side remote from the carrier layer with a protective layer, in particular a dielectric protective lacquer.
- the line layer in particular with at least one spring contact and / or at least one solder joint and / or at least one conductive rubber and / or at least one self-adhesive copper binder (copper adhesive tape) indirectly, in particular via a board, or directly with the electrical Be connected control unit.
- conductive transparent glass coatings for example - ITO surfaces, can be easily contacted with conductive rubber or self-adhesive copper binders.
- the surface of the actuation area may be flat or curved.
- a curved surface has the advantage that it is tactile better detectable.
- FIG. 2 schematically shows a detail view of the sensor layer and the line layer according to FIG. 1 in the region II there;
- FIG. 4 schematically shows a detail view of the sensor layer and the line layer according to FIG. 3 in the region IV there.
- Figure 1 is a total provided with the reference numeral 1 capacitive sensor of an electrical actuating device, not shown, a sanitary fitting shown in cross section.
- the actuating device With the actuating device, the water temperature and / or the water volume flow of the water emerging from the sanitary fitting are adjustable via a mixing valve, not shown.
- the sensor 1 has as an actuating region a lens-shaped sensor hood 3 with a convexly curved outer surface viewed from an actuating side in FIG. 1 at the top.
- the sensor hood 3 terminates at the bottom with a flat bottom surface 5.
- the sensor hood 3 has a layer structure of a
- a carrier layer 7 of electrically insulating, transparent glass is arranged on this side.
- an electrically conductive sensor layer 9 of aluminum is vapor-deposited directly from below, ie on the side facing away from the actuation side of the sensor hood 3.
- the sensor layer 9 is coated in FIG. 1 from below on its side facing away from the carrier layer 7 with a layer of dielectric protective lacquer 19.
- the protective varnish 19 is followed by a layer of a dielectric gel 21 having a high dielectric constant, on which the bottom side faces away from the carrier layer 7 Side of the sensor layer 9, an electrically conductive line layer 23 is arranged made of brass.
- the sensor layer 9 and the line layer 23 form the plates of a capacitor, which are galvanically separated from one another by the protective varnish 19 and the gel 21 as a dielectric.
- the sensor layer 9 is thus capacitively connected to the line layer 23.
- the line layer 23 is connected in FIG. 1 to the right via a solder connection 30 to a signal line 32.
- the signal line 32 leads to a contact 33 of a planar board 34.
- the line layer 23 may alternatively, as shown in Figure 1 on the left, be electrically connected from below via a spring contact 36 of a spring 37 made of electrically conductive material with a contact 38 of the board 34.
- the circuit board 34 is arranged above the bottom surface 5 parallel thereto within the area bounded by the sensor hood 3.
- a control line leads to the electrical control unit, which is so indirectly functionally connected to the sensor layer 9.
- control unit capacitive changes in the sensor 1 are detected when touched, for example, with a finger and the mixing valve is controlled accordingly.
- the sensor hood 3 is touched from the operating side.
- another dielectric having a high dielectric constant for example a highly flexible adhesive, may be arranged between the sensor layer 9 and the conductor layer 23.
- a minimum air gap may be provided.
- FIG. 3 and in FIG. 4 in detail, those elements that are similar to those of the first embodiment described in FIG. 1 and FIG. 2 are provided with the same reference numerals plus 100, so that with respect to their description to the comments on the first embodiment reference is made.
- This embodiment differs from the first in that the sensor 101 is not curved but flat.
- the line layer 123 is not capacitive but is galvanically connected to a sensor layer 109. A dielectric layer between the conductor layer 123 and the sensor layer 109 is therefore dispensed with.
- the conductor layer 123 is a transparent, electrically conductive coating, preferably an ITO layer, which is applied directly from below to a carrier layer 107 made of glass in FIGS. 3, 4.
- the sensor layer 109 is aluminum deposited directly on the side of the conductor layer 123 facing away from the carrier layer 107.
- the sensor layer 109 and the line layer 123 thus form a capacitor plate of the capacitive sensor 101.
- the sensor layer 109 is coated in FIGS. 3, 4 from below on its side facing away from the carrier layer 107 with a layer of protective varnish 119.
- the sensor layer 109 does not extend over the entire lower surface of the conductive layer 123, so that on the underside of a non-damped aluminum edge 131 remains free.
- a substantially parallelepiped conductive rubber 132 of electrically conductive material forms a contact 136 with the underside of the conductive layer 123 with its upper end face.
- the conductive rubber 132 leads vertically down to a contact 138 on a parallel to the sensor hood 103 arranged planar board 134.
- the conductive rubber 132 forms a galvanic connection between the conductor layer 123 and the board 134th
- the circuit board 134 in turn is analogous to the first embodiment connected to a control unit, not shown.
- the actuation of the sensor 101 is analogous to the first embodiment.
- the carrier layer 7; 107 may be in both embodiments instead of glass from another electrically insulating, durable material with smooth surface for applying the sensor layer 9, 109, in particular made of porcelain or plastic, in particular crystal clear plastic such as acrylic or polycarbonate.
- the surface of the sensor hood 3; 103 may instead of flat or convex curved and any other way, for example, be concave, curved.
- the sensor layer 9; Viewed 107, leads to an aesthetic appearance; also another conductive layer may be vapor-coated surface, through the transparent support layer 7-109, instead of a aluminum ".
- sensor layer 9 instead of aluminum, another metal, for example silver, as sensor layer 9; Be vapor-deposited. It is also possible to vapor-deposit metals which have a corresponding effect, for example, as color filters and therefore reflect only a corresponding color spectrum.
- the wiring layer 23; 123 or the sensor layer 9 can instead of a spring contact 36 of a spring 37, a signal line 32 with a solder joint 30 and a conductive rubber 132 indirectly with self-adhesive copper binder (copper adhesive tape), in particular via the board 34; 134, or directly, waiving a board 34; 134, be connected to the electrical control unit.
