Description

The invention relates to a washing device according to the preamble of the claim 1.

In the context of the present description, a washing device is understood to mean a device in the manner of a washing or sinking unit, a bidet, WC, urinal, a bathtub or a shower cabin or, if appropriate, in the manner of a drying device for contactless drying of hands. Washing and sinking units and drying facilities of this type are used in wet rooms of all kinds, for example for personal hygiene in bathrooms,
for rinsing purposes in kitchens, for cleaning purposes in semi-public and public sanitary facilities such as toilets and shower rooms, as well as in laboratories, food industry, retirement and nursing homes, and hospitals. As materials for basins for installation or installation of washing device of this type are depending on the use of porcelain, earthenware, stone, especially natural stone such as marble, plastic, enamelled sheet metal and chrome steel sheet; Modern cymbals are sometimes made of opaque plastics such as Corian and of transparent or translucent materials such as acrylic, glass or quaryl. As materials for housing of dryers of the type mentioned are mainly metals, such as painted or enamelled sheet or bright chrome steel sheet known.

It should be mentioned here that under the term fresh water in the context of the present Description of the pool inflowing cold and / or warm water and the term dirty water from the basin effluent water including the additives contained therein.

The washing facilities consist essentially of a basin and a Supply fitting and usually also have a drain valve. The basin is bounded by a pool wall and is attached to a structure or on a building wall fastened. The supply fitting, commonly called a faucet is referred to, has a nozzle on the fresh water into the tank arrives. The nozzle is with a building-side supply line for the fresh water connected; the fresh water is the tank from a tank or a Power supplied. The supply fitting further includes a shut-off member, by means of an actuating element such as a knob or a lever is movable or rotatable or displaceable, between a closed position and at least one open position. In the closing position is the Inflow of fresh water to the pelvis prevented, in the or the Open positions can be the fresh water with greater or smaller flow rate through the neck into the basin. The supply fitting is preferably in attached to a first breakthrough of the pelvic wall. The discharge of the Dirty water is preferably via a second breakthrough, in which usually a drain fitting is mounted in a drain pipe. The drain fitting usually includes an odor trap, which is usually referred to as a siphon becomes.

The conventional washing devices described above are numerous Disadvantages, depending on their intended use more or less strong in weight. In particular, it is for various reasons such as risk of damage through vandalism, ease of use and cleaning disadvantageous that the mounted on the edge region of the cavity of the basin fittings protrude into the interior of the basin.

Although virtually vandal-proof washing facilities are known which ago especially in washrooms used by industrial enterprises. They point round, all-round basins made of chromium steel sheet on, in the middle a sheathed with chromium steel sheet, protruding far beyond the edge of the pool Include column in which the supply line of the fresh water is arranged. The column has openings in its upper region, through which the Fresh water flows out. This washing facility is only suitable for cases in which a certain number of people always make use of at the same time, since an individual control of the water supply is not provided.

Also known is a virtually vandal-proof drinking water dispenser, actually a fountain, in which a nozzle for the supply of drinking water in the lowest point of the pelvic wall is integrated. Flows through the nozzle Drinking water in small quantities, ie in a thin stream upwards, such that the beam extends just above the upper pelvic boundary. The actual, upwardly concave pool is outside the beam area Covered by a hood largely to a purpose-unfamiliar use to prevent the drinking water dispenser. The supply of drinking water takes place continuously, neither the amount of drinking water nor its temperature can be controlled by the user of the drinking water source.

From WO 93/10311 a generic washing device is known which automatically works without the user having any part of the device must touch. Two sensors provide the presence of the person to be washed Hold hands and trigger a time relay controlled cleaning process. However, the user can not change the timing of network water, cleaning agent and wash water inlet still change this is able to change the Water temperature to suit his needs.

From DE 35 14 640A is still a washing device with the Features of the preamble of claim 1 known.

It must therefore be stated that no washing facilities, in particular in the form of washing and sinking, are known, which are both a sufficient Ensure vandal-proofing and, moreover, in terms of production, Cleaning options and economical water consumption, in particular but in terms of hygiene and comfort in use, are optimally designed. A similar finding may also apply to dryers be made.

The object of the invention is therefore to provide a washing device of the aforementioned To provide a type which avoids the disadvantages of the prior art.

The solution of this task is - according to a first aspect - by the Features of claim 1, by a Washing device with a Device for control and / or regulation a medium inflow through a supply unit is proposed, which at least includes a shut-off. Each obturator is by means of an actuating element in a closing position or at least one open position can be brought. It also includes the device comprises a sensor device for contactless determination of the Presence of body parts to be acted upon by this medium. The inventive Device is characterized in that this sensor device in addition to the contactless determination of the relative position of these Body parts in relation to the washing device and for outputting signals is formed, which act on the actuators so that these Shut-off in one of the presence and position of this medium to be acted upon body parts to bring appropriate position, training the inventive device for control and / or regulation result from the dependent claims.

Furthermore, this task is by proposing a Method for the contactless control and / or regulation of a medium inflow by a supply unit to a washing device according to claim 13 solved. In this case, the supply unit comprises at least one shut-off member and each shut-off member is by means of an actuating element in a closed position or at least one open position can be brought. In addition, the device includes a sensor device for contactless detection of the presence of to be acted upon by this medium body parts, with which at least one (high-energy) field is generated. The inventive method is characterized characterized in that the contactless detection of this at least one Field with the sensor device, the relative position of this matter in relation to the washing device detects and outputs signals that are so on the actuators Act that these the shut-off in one of the presence and the position of the body parts to be acted upon by this medium Position. Further developments of the inventive method result from the dependent claims.

An inventive washing device therefore differs from conventional devices in that it has a feeding device, their operation depending on the presence and position of the person to be washed and possibly body parts (e.g., hands) to be dried.

• kostengünstig herstellbar sind, da die Aufwendungen für die gewissermassen redimensionierte Zufuhrvorrichtung bedeutend geringer sind;
• angenehmer, einfacher und kostengünstiger sowie mit hygienisch und visuell besseren Ergebnissen zu reinigen sind - nicht nur entfällt die Reinigung einer Zufuhrarmatur, sondern es sind auch praktisch keine Übergangsbereiche zwischen Becken und Zufuhrvorrichtung vorhanden, welche bekanntlich schwierig zu reinigen sind - das zu reinigende Objekt ist voll sichtbar;
• einen höheren Gebrauchskomfort bereitstellen, da der Zugang zum Becken nicht oder kaum durch eine Zufuhrarmatur behindert wird und insbesondere dadurch, dass alle Funktionen der Zufuhrarmatur durch den Benutzer berührungslos gesteuert werden können. Dies ist aus hygienischer Sicht vorteilhaft;
• ästhetischer sind, weil grosse sichtbare Bestandteile der Zufuhrvorrichtung fehlen;
• Wasser sparend sind, weil durch die Sensorsteuerung für den Zufluss des Frischwassers ein übermässiger und nutzloser Wasserverbrauch unterbunden wird, was aus Gründen der Hygiene, des Bedienungskomforts sowie aus ökologischen wie auch ökonomischen Gründen vorteilhaft ist.

Advantages compared to the prior art result, for example, from the fact that the proposed washing devices:

• are inexpensive to produce, since the expenses for the somewhat redimensioned supply device are significantly lower;
• more pleasant, simpler and more cost-effective as well as to clean hygienic and visually better results - not only eliminates the cleaning of a supply fitting, but there are virtually no transition areas between the basin and supply device available, which are known to be difficult to clean - the object to be cleaned is full visible, noticeable;
• provide a higher comfort of use, since the access to the pool is not or hardly obstructed by a supply fitting and in particular by the fact that all functions of the supply fitting can be controlled by the user without contact. This is advantageous from a hygienic point of view;
• are more aesthetic because large visible components of the feeder are missing;
• Save water, because excessive and useless water consumption is prevented by the sensor control for the inflow of fresh water, which is advantageous for reasons of hygiene, ease of use and for environmental as well as economic reasons.

The neck of the feeder can be through the material of the pool wall be formed, wherein the boundary of the breakthrough at the same time the wall forms the neck. For pools with pelvic walls of low wall thickness Sheet metal can be a deep drawn neck piece, preferably on the outside of the basin, be formed. The neck can also be replaced by a breakthrough or Outbreak recorded tubular insert be formed. He can there be secured by suitable means; this comes screwing, pressing, Bonding or optionally soldering in question. Preferably, the exit area of the neck so formed that a mixed with air, pearling Fresh water jet is generated as a result of the use of the washing device less splashing occurs.

It is recommended for uses in particularly vandal-endangered areas itself, the proposed washing device in such a way that the outlet cross-section of the neck practically invisible and for a user of the Washing device is not accessible. For this purpose, the nozzle of the Feed device preferably integrated into the pool wall so that Outlet cross section substantially flush with the adjacent inner surface the pool wall is located. The nozzle is stationary in a first Breakthrough mounted. Such a washing device is vandal-proof, as no Fittings of the feeder are present, to which the users Have access. This can result in significant savings for repairs be incurred in conventional washing facilities. Cover through Rosette like lock cylinder possible. Even if one with a firmly mounted Effervescent outlet end of the neck by a little into the basin Vandalism can be prevented by having an exit end frustum-like rosette is mounted, roughly in the way she is often used to protect lock cylinders.

The proposed washing device is also suitable for areas in which no vandalism is to be feared. In such areas, it is not imperative that the neck is integrated in the pelvic wall and firmly mounted therein, that its outlet cross-section is practically flush with the inner surface of the pool wall is arranged. It may even be desirable that the neck has a slightly projecting into the interior of the pelvis neck approach, which extends at least approximately in the direction of the breakthrough. The neck approach is dimensioned so that the outlet cross-section of the nozzle in located near the pool wall, thus free access to the pool is held. This design of the neck would also allow the neck approach To attach operating units, with which, for example, the time inflowing amount of fresh water, the mixing ratio of warm to cold fresh water or the temperature of fresh water and the beam configuration could be affected. In addition, the neck approach be used as a decorative element.

The neck can also be placed on the sink. The neck can Also be flexible or multi-part design, such that the projecting into the basin Neck approach about one or two axes or pivotable about a point is. It is also possible to design the neck so that the position of the neck approach from the amount or pressure of the inflowing Fresh water is determined.

In certain cases, especially for rinsing purposes in kitchens or laboratories or also for washing hair in bathrooms or hairdressers, it is desirable the nozzle via a flexible line with the fresh water supply to connect. The nozzle and hose can then be removed from a rest position in which only the nozzle does not or only with the neck approach into the basin protrudes, in one Be drawn active position in which the neck is guided manually.

To increase the ease of use, the proposed washing device be designed so that by the already mentioned neck or optionally not only fresh water through one or more additional nozzles but also additives, generally in fluid form, like detergents respectively Soap solutions and / or a disinfectant used after washing or disinfectant and optionally warm air for drying the washed article or body part is supplied.

The control of the inflow of fresh water is not done directly by the manual Actuation of an actuating element such as a lever or a rotary knob, but remotely controlled by means of a sensor device, the via a pneumatic or electrical line arrangement with the obturator connected is. Here, however, the temporally inflowing Amount of water, the mixing ratio of warm to cold fresh water and the Beam configuration can be influenced by the user, if appropriate Sensor device is arranged. Conventional washing facilities with common fittings in the manner of water taps, especially in public Area, are already occasionally with on pressure or touch Reactive sensors equipped by hand or foot pressure be operated. For hygienic reasons, sensors are by foot pressure be pressed, preferable, because a renewed pollution of the just washed Hands by touching the supply device deleted. Furthermore Today, there are systems that work with infrared or radar. These systems however, they only allow the supply to be turned off.

Not only for hygienic reasons but also for ecological reasons, that is to reduce the amount of fresh water consumed and the energy consumed it is particularly advantageous to supply the fresh water and preferably its Quantity and temperature with the help of non-contact sensors to remote control, which only bring the obturator in an open position, if there is an object or body part to be cleaned in the pool. Such sensors largely prevent misuse by a user and allow an economical fresh water consumption.

• Die trockenen Hände werden in die Mitte des Waschbeckens gehalten. Die beiden links und rechts, symmetrisch gegenüber dem Frischwasseraustritt angeordneten und jetzt praktisch gleich angeregten Sensoren schalten die Frischwasserzufuhr (Kalt- und Warmwasser) ein. Die Hände werden benetzt.
• Wird die rechte, die Temperatur einstellende Hand nach rechts gegen den rechten, nun höher angeregten Sensor bewegt, so wird das Wasser kälter bis die beiden Hände in der Mitte zusammengeführt werden.
• Wird linke, die Temperatur einstellende Hand nach links gegen den linken, nun höher angeregten Sensor bewegt, so wird das Wasser wärmer bis die beiden Hände in der Mitte zusammengeführt werden.
• Jedes Vorschieben der beiden nassen Hände gegen einen dritten, in unmittelbarer Nähe des Frischwasseraustritts angeordneten Sensor löst eine einmalige Zugabe von flüssiger Seife zum Frischwasser aus. Mit Seife und Frischwasser der gewählten Temperatur können nun die Hände gewaschen werden.
• Ein Zurückziehen beider Hände aus dem Waschbecken unterbricht die Frischwasserzufuhr und ein Wiedereintauchen der nassen Hände (linke Hand in der Nähe des linken Sensors und rechte Hand in der Nähe des rechten Sensors) schaltet die Warmluftzufuhr ein, die vorzugsweise aus der gleichen Austrittsöffnung wie zuvor das Frischwasser und die Seife ins nun als Trockeneinrichtung funktionierende Waschbecken strömt.
• Wird die linke, die Warmluft fühlende Hand ruhig gehalten und die rechte, die Temperatur einstellende Hand nach rechts gegen den rechten, nun höher angeregten Sensor bewegt, so wird die Warmluft kälter bis die beiden Hände in der Mitte zusammengeführt werden.
• Wird die rechte, die Warmluft fühlende Hand ruhig gehalten und die linke, die Temperatur einstellende Hand nach links gegen den linken, nun höher angeregten Sensor bewegt, so wird die Warmluft wärmer bis die beiden Hände in der Mitte zusammengeführt werden.
• Nach dem Zusammenführen und Trocknen der Hände wird die Warmluftzufuhr unterbrochen, sobald die Hände aus dem Wasch-/Trockenbecken herausgenommen werden.

As an example of this remote control, an exemplary selected sequence of hands-washing drying in a combined washing / drying basin is described:

• The dry hands are held in the middle of the sink. The two left and right, symmetrically arranged opposite the fresh water outlet and now practically the same excited sensors turn on the fresh water supply (cold and hot water). The hands are wetted.
• If the right, the temperature-adjusting hand is moved to the right against the right, now higher stimulated sensor, the water will be colder until the two hands are brought together in the middle.
• If the left, the temperature setting hand is moved to the left against the left, now higher stimulated sensor, the water is warmer until the two hands in the middle are merged.
• Each advancing of the two wet hands against a third, arranged in the immediate vicinity of the fresh water outlet sensor triggers a one-time addition of liquid soap to the fresh water. With soap and fresh water of the selected temperature, the hands can now be washed.
• Retraction of both hands from the sink interrupts the supply of fresh water and a re-immersion of the wet hands (left hand near the left sensor and right hand near the right sensor) turns on the hot air supply, preferably from the same outlet as before the fresh water and the soap flows into the now functioning as a drying device sink.
• If the left hand, which feels warm, is kept still, and the right, temperature-adjusting hand is moved to the right against the right, now higher-excited sensor, the warm air will become colder until the two hands are brought together in the middle.
• If the right hand, which feels the warm air, is kept still and the left hand, which sets the temperature, moves to the left against the left, now higher excited sensor, the warm air will become warmer until the two hands are brought together in the middle.
• After merging and drying the hands, the supply of hot air is interrupted as soon as the hands are taken out of the washing / drying basin.

For the safety of the users are the maximum temperatures for water and air preferably fixed to a safe value of 55 ° C and can not under any circumstances be crossed, be exceeded, be passed.

The sensors of the sensor device can be in or on the pelvis or in the vicinity of the washing device, for example on or in the basin carrying structure, on or in a building wall, a floor or a ceiling. to be ordered; is the washing device at risk of vandalism, so it is advisable to arrange the sensors so that the users do not Have access to it. In addition, the sensors can be arranged in one on the basin Stutzen, which also provides the medium supply, be arranged. The term "medium" includes in the context of the present invention all fluid media used to clean and / or dry matter can be, such as Detergent, cold water, hot water, mixed water, Disinfectants, gases such as nitrogen gas or heated air. The term "Matter" includes all body parts or objects that are used with the media Washing and / or drying can be applied.

As described above, the proposed washing device can be formed be that the supply of fresh water, that is its temporally incoming Quantity and its temperature or the mixing ratio of Hot water to cold water can be influenced by the user. Quantity and / or Temperature of the fresh water or the medium but can also be otherwise be determined, for example, as follows:

The amount of inflowing fresh water can be fixed or by Influencing suitable parameters are set; for example, the Regulation of the amount depending on the pressure in the supply line done. The temperature of the inflowing fresh water can be regulated to a fixed value or controlled or adjusted and stored.

So far, only on the supply of the medium to the basin and the used Feed device discussed in more detail. As mentioned briefly above, have usual washing facilities also have a drain fitting over the soft Dirty water in the building-side sewer pipe and then in the sewer flows.

It should be mentioned here only for the sake of completeness, that the drain valve either allow the continuous drainage of dirty water or a conventional Device may have, with which the outflow of water is prevented from the pelvis, in the latter case, the arrangement of a non-closable overflow opening necessary or at least extremely is recommended.

The drain fitting is usually with a multi-angled odor trap device, which is also referred to as a siphon provided. This odor trap is designed so that the line between the Basin and sewer system in at least one cross-section, but in practice in a certain area, constantly filled with water completely. Because of this Water is to a certain extent a plug formed, which prevents Smells of the sewer into the pool and thereby flow into the room. Becomes a Basin is not used for a certain time, so will, depending on ambient temperature and ambient pressure, a part of the plug forming Water evaporates, so that the odor trap is not maintained. To prevent this, the proposed washing device - as by the way each other provided with an automatic dispenser for fresh water Washing device - with a protective device to maintain the odor protection be provided. This guard has one in the area arranged the siphon sensor, which on a change of a state variable in the siphon, such as water level or smell, reacts, and in case of decay of the odor trap the influx of a small Amount of fresh water to the basin causes the odor trap restore. To maintain or restore the odor trap can also be provided, each after a certain time interval or after a certain time interval from the last use of the Washing device to supply a small amount of fresh water.

• Warm air for drying hands.

Such arrangements are particularly suitable for laboratories and hospitals.

In Fig. 5, a nozzle 20 is shown, in the region of its outlet cross-section 21 contains a shower 27. In addition, this nozzle 20 has a Secondary nozzle, which forms an additive connection 28, through which a suitable Additive 102 can be supplied. Fig. 6 shows another nozzle 20, with which an additive 102 centrally or within the jet 100 of the fresh water can be fed.

Fig. 7 shows variants of a set to a sink 10 nozzle 20 with integrated water outlet and sensors. Fig. 7A shows a fitting with two Sensors S1, S2 for detecting the presence and position of the hands in the sink (optical, ultrasound, pyro etc.). Fig. 7B shows a first fitting with particularly preferred, integrated sensors for generating an optical Feldes: Four cells are arranged on the nozzle 20, namely two transmitters E1, E2 and two receivers R1, R2 (see also Fig. 9, where these cells in the pelvic wall 14 are arranged). In this capacitive solution, these cells exist essentially four plates. Fig. 7C shows another fitting with integrated Sensors for generating an electric field, wherein the four cells E1 or R1 and E2 or R2 arranged in a sleeve at the foot of the nozzle are and the fields A1, A2 and their overlap area A3 generate or monitor.

As an alternative to the shown Fig. 7, the inlet nozzle 20 also in a wall 1, on which the washbasin 10 is positioned, arranged above the basin 12 be. Left and right of the inlet nozzle 20 are then preferably the cells E1, R1 or E2, R2 (see also Fig. 9) for generating an electrical or optical field also in the wall 1 above the pool 12. The Sensor device 50 is preferably (see also Fig. 13) together with the Stub 20 combined in a module 60.

A variant for the additive feed is shown in FIG. 8. Here serves the Nozzle 20 for the supply of fresh water, while the additive supply an additional nozzle 30 is provided. A disadvantage is the greater design effort, advantageous is that in cases where the fresh water is also consumed should, in the nozzle 20 no residues of additives 102 are present.

The arrangement and mode of operation of the sensor device 50 will be described below described with which the influx and / or the temperature of the fresh water and optionally the additive (s) to the pelvis.

It should be noted at this point that the sensor devices described below even on conventional washing facilities with not in the pool wall integrated socket can be used in which the Fresh water supplied in a conventional manner via a nozzle of a faucet is, but this faucet but no actuator, so no knob or lever, for moving the obturator, since this with Help the sensor device is operated remotely controlled. However, the combination is of the spigot integrated into the pelvic wall with the remote controlled Actuation of the shut-off as described above particularly advantageous.

Another and - compared to the already described way of working - very simple Variant of the design and operation of the basin is the following: An object to be cleaned, which is also a part of the body can be kept in a basin. A sensor device of any kind senses the presence of this object or body part and acts on a shut-off that this from its closed position in one Open position is moved, allowing fresh water through one in the basin integrated nozzle flows into the interior of the basin.

• bei Entfernung des Gegenstandes aus dem Becken; oder
• eine kurze Zeitspanne, zum Beispiel eine Sekunde, nach Entfernung des Gegenstandes aus dem Becken; oder
• nach einer bestimmten, vorwählbaren Zeitspanne, während welcher Frischwasser zugeströmt ist; oder
• nach einer Kombination der drei soeben genannten Kriterien.

The inflow of fresh water can be interrupted in various ways, for example:

• upon removal of the object from the basin; or
• a short period of time, for example one second, after removal of the object from the basin; or
• after a certain preselected period of time during which fresh water has been added; or
• after a combination of the three criteria just mentioned.

In the variant shown in FIG. 9, the sensor device which is only in Fig. 13 is designated by 50, four on the tank 12 and in the pool wall 14th arranged cells, namely two transmitters E1, E2 and two receivers R1, R2. In a capacitive solution, these cells essentially consist of four plates, which form an E-field, in an optical solution of two optical Transmitters and two optical receivers.

The number of cells used is not limited, in principle, a be provided to n cells or one to n sensors. The cells react as Barrier cells and as reflex cells. A barrier reaction generally occurs when an object enters the pool 12. A reflex reaction takes place when an object enters a very specific area of the pool 12, for example, when a washcloth is hung over the edge of the basin 12 becomes.

• Wird ein Gegenstand in die Mitte des Beckens 12 gehalten, so wirken Zellen E1,R1 und E2,R2 als Schranken-Zellen, was durch die Pfeile (a) dargestellt ist, und die Zufuhr von Frischwasser wird veranlasst. Nach Entfernung des Gegenstandes wird die Zufuhr von Frischwasser sofort oder nach einer gewissen Zeitspanne beziehungsweise Verweilzeit unterbrochen; wird nur ein Gegenstand wie Waschlappen über den Beckenrand gelegt, so erfolgt eine Schranken-Reaktion und der Zustrom von Frischwasser würde beginnen; dieser Zustrom wird aber verhindert durch die gleichzeitig erfolgende Reflex-Reaktion; die durch die Pfeile (b) dargestellt ist.
• wird ein Gegenstand ins Becken 12 gehalten, so erfolgt eine Schranken-Reaktion und die Zufuhr von Frischwasser kommt in Gang. Anschliessend kann durch Verursachung einer Reflex-Reaktion die zeitlich Zuströmende Menge an Frischwasser und/oder die Temperatur des zuströmenden Wassers gesteuert werden.

With this arrangement, various operations can be carried out:

• When an article is held in the center of the pool 12, cells E1, R1 and E2, R2 act as barrier cells, as indicated by the arrows (a), and the supply of fresh water is caused. After removal of the object, the supply of fresh water is interrupted immediately or after a certain period of time or residence time; if only an object such as washcloths is placed over the edge of the pool, a barrier reaction takes place and the influx of fresh water would begin; but this influx is prevented by the simultaneous reflex reaction; which is represented by the arrows (b).
• if an object is held in the tank 12, a barrier reaction takes place and the supply of fresh water starts. Subsequently, by causing a reflex reaction, the amount of fresh water flowing in time and / or the temperature of the inflowing water can be controlled.

In the variant shown in FIG. 10, two sensor devices S3, S4 are arranged, for example, ultrasonic sensors. Each of the sensor devices S3, S4 monitors its surroundings in an area A3 or A4 of a drop-shaped one Cloud. These areas A3, A4 form an overlapping area A5 in the middle of the basin 12.

• Wird ein Gegenstand in die Mitte des Beckens 12 bzw. in den Überschneidungsbereich A5 gehalten, so wird er von beiden Sensorvorrichtung S3,S4 erkannt und die Zufuhr von Frischwasser wird veranlasst. Nach dem Entfernen des Gegenstandes wird die Zufuhr von Frischwasser sofort oder nach einer gewissen Zeitspanne beziehungsweise Verweilzeit unterbrochen.
• Wird ein Waschlappen über einen der Sensoren S3, S4 gelegt, so wird der Zustrom von Frischwasser verhindert.
• Wird ein Gegenstand durch beide Sensoren S3, S4 erkannt, so wird die Zufuhr von Frischwasser veranlasst. Erkennt anschliessend einer der Sensoren S3, S4 eine Näherung, so wird durch ihn eine Steuerfunktion ausgeübt, beispielsweise kann die Menge oder die Temperatur des zuströmenden Frischwassers gesteuert werden.

With this arrangement you get the following options:

• If an object is held in the middle of the basin 12 or in the overlapping area A5, it is detected by both sensor devices S3, S4 and the supply of fresh water is caused. After removal of the article, the supply of fresh water is interrupted immediately or after a certain period of time or residence time.
• If a washcloth is placed over one of the sensors S3, S4, the influx of fresh water is prevented.
• If an object is detected by both sensors S3, S4, the supply of fresh water is initiated. If one of the sensors S3, S4 subsequently recognizes an approximation, a control function is exercised by it, for example the quantity or the temperature of the inflowing fresh water can be controlled.

In another variant, not shown, the supply of water through Contact a cell or a marked point causes. Preferably there are two cells or marker points, e.g. Red and blue. By staying longer on the red or blue Cell is caused to change the temperature of the incoming fresh water increases or decreases. By prolonged simultaneous actuation of both cells or marker points becomes the amount of incoming fresh water affected. By briefly pressing a cell, the supply of Fresh water interrupted.

The variant shown in FIG. 11 provides a sensor device in which a transmitter E5 and two receivers R5.1, R5.2 arranged on the edge of the basin 12 and are switched that in a region A6 by certain hand movements, for example, on the edge of the basin 12 to or in the depth of the Pelvis 12 down, the amount and / or temperature of the inflowing Fresh water is influenced.

For a further variant according to FIG. 12, two sensor units are used. Sensor devices may be used which can be used after any Technology work, for example, acoustically, optically, capacitively. Particularly suitable are capacitive E fields A1, A2 forming sensor units E6, R6 and E7, R7, which may be integrated in the pool wall 14, for example. Here are generates two electric fields A1, A2, with an overlapping area A3. If an object is in the middle of the pool 12 or in the overlap area A3, it causes a reaction of both recipient cells R6, R7, and the supply of fresh water is initiated. It will then one of the electric fields more strongly influenced, so can the amount of fresh water and its temperature can be varied. This is also possible with an arrangement, in which the sensor device operates according to the reflex method and transmitter E6 or E7 and receiver R6 and R7 respectively on the same side of the basin 12 lie. In combination with a washbasin 10 and a sensor device 50 according to FIG. 12 may also conventional fittings be used. These are then transmitted via the sensors and actuators operated, so that even with such conventional fittings, the fresh water temperature Can be adjusted contactlessly by the user.

The washing device 10 shown in FIG. 12 thus comprises a device for controlling a medium flow through a supply unit. The basin 12 can also be referred to as a charging device, because the hands be charged with water. The supply unit comprises at least one obturator and each obturator is by means of an actuating element in one Closing position or at least one open position can be brought. This device 2 for controlling a medium inflow comprises a sensor device 50 for non-contact determination of the presence of to be acted upon by this medium Matter or hands. This sensor device 50 is also to contactlessly determine the relative position of the hands with respect to the Basin or the applying device and for outputting signals formed, which act on the actuating elements, that these the blocking members in a position corresponding to the presence and position of the hands bring.

Another variant, which can be combined with the above variants, provides, in certain time intervals and / or after a certain number of uses to use a larger amount of fresh water for the washing device, preferably hot and with a detergent or disinfectant to the Clean the pool.

According to FIG. 13, the sensor device 50 together with the connection 20 in FIG a module 60 are arranged, which is a simplification or the replacement no longer functional parts allowed and visually advantageous effects results.

The nozzle 20 or the sensor device 50 may in an overflow opening 17th be arranged the pool wall. A particularly advantageous arrangement shows Fig. 14, according to which both the nozzle 20 and the sensor device 50 are arranged in the overflow opening 17.

According to FIG. 15, the cells E8 or R8 and E9 or R9 can be in the rear edge be arranged of the basin and the electric fields A1, A2 or their Create or monitor overlapping area A3.

The different modes of action with the proposed washing device possible, can also be visualized.

• Leuchtmittel beziehungsweise Anzeigemittel im Becken oder in der Umgebung des Beckens oder an einer Überwachungsstation; die Anzeige kann durch Variation der Intensität oder der Anzahl der Leuchtmittel erfolgen;
• Display zum Anzeigen verschiedener Grössen, analog und/oder digital;

As examples of visualization, the following possibilities are mentioned:

• Illuminants or display means in the basin or in the vicinity of the pool or at a monitoring station; the display can be done by varying the intensity or the number of bulbs;
• Display for displaying different quantities, analog and / or digital;
• Display can be designed as a touchscreen and thereby usable as a sensor device;
• Acoustic display, ie beeps and / or speech;
• Parameterization of various rinsing and cleaning programs via remote control and building control systems;
• Display of reaching a maximum temperature of fresh water or hot air.

As mentioned above, the basins 12 not only have feeders but also drain fittings 19, which in a second opening 18 of Pelvic wall 14 are mounted. Basin not considered a pure flow-through basin but in which a certain amount of fresh water - if necessary with an additive - to be accumulated, have drain fittings 19 with a closing organ on. The closing organ can be manually or, preferably, operated remotely, in a manner analogous to that shut-off device; Basin 12 with closing organs generally have one Overflow opening 17 in the upper pelvic area, to overflow the pelvis to avoid. On such an overflow opening may be omitted be, if a sensor is present, the closing organ in his Open position brings as soon as the water level in the basin reaches a certain level has reached and / or interrupts the supply of water.

Fig. 16 shows a vanity with an inserted into the surface of the basin Inlet nozzle 20. The sensor device 50 for generating an electrical Field comprises cells E10 and R10 and E11 and R11, respectively the cells are arranged in Fig. 12 at the side edge of the basin 12. In addition, the sensor device comprises a transmitter cell E12 and a receiver cell R12, which side by side at the bottom of the basin near the opening 18 for receiving the drain fitting 19 - to generate a third electric field - are arranged. With this arrangement, a field-enhancing or field reducing object (e.g., hands) 3-dimensionally which provides an additional extension of control options in the context of the present invention allows. In addition, the water surface can be detected in the pelvis and if necessary, i. when crossing one certain level of inflow of fresh water stopped and / or the Closing member to be opened in the process. An overflow opening 17 is then not more required. This level control can also be used in a basin a conventional, known faucet can be used. Thus, can up a, known to be dirt-prone overflow set to be omitted. One Overflow of the pelvis is successfully prevented by the sensors, if the supplied amount of fresh water can not be removed, because For example, a washcloth covers the drainage opening.

A corresponding overflow protection can also be realized if distance sensors (e.g., optical, acoustic, radar, capacitive, etc.) at any point, preferably on the armature, on the pool, or on a tank-bearing Wall 1 can be arranged. Also, corresponding reflex or passage barriers be installed in the pool 12. Another embodiment for overflow protection, a communicating with the pool 12 includes Vessel (not shown) containing e.g. behind the washing device 10 is arranged is and to which a level sensor is connected. All of these embodiments overflow protection is common that when reaching a predetermined water level in the sink the fresh water supply automatically is interrupted. In addition, it can be provided that the supply all other media is interrupted.

FIG. 17 shows a washbasin 10 with a variant of that shown in FIG. 7C Neck, in frontal view. The two cell pairs E13 or R13 and E14 and R14 are attached to the highest point of the underside of the bent nozzle 20 and generate or monitor the two fields A3, A4 and the overlap area A5. Even with this arrangement, the level in the basin 12 are monitored.

Fig. 18 shows a, compared to FIG. 16 illustrated, simplified embodiment a sensor array, in a front view. The two cell pairs E10 and R10 (shown) and E11 and R11 (not shown) are highest, by a maximum Level attached specific point of the pool wall 14 and produce or monitor two electric fields. Rises the water to the height the receiver cells E10 and E11, the electric fields are greatly changed. This change will trigger the stopping of the fresh water supply used and / or to open the drain valve. Thus, also with this Arrangement monitors the level in the basin and an overflow opening 17 be waived. This embodiment is suitable (as described) for Changing the fresh water temperature by the user. However, if only the level should be monitored, it is sufficient for this purpose the provision of only one transmitter cell E10 and one receiver cell R10 (shown).

The drain fitting includes a siphon containing an odor control device between the basin and the sewer forms by at least one Cross section of the siphon constantly contains water, creating a kind of water plug is formed. If a washing device is not used for a long time, so some of the water in the siphon can evaporate, leaving the odor barrier no longer exists. To prevent this, in the area of Siphons be arranged a siphon sensor, which is coupled to the obturator is, and the absence of the odor barrier due to low water level in the siphon the obturator briefly moves into its open position, so that a small amount of fresh water flows in, which is sufficient to the odor barrier to ensure again. Alternatively, the addition of a small amount Fresh water to maintain or restore the odor trap as mentioned above with a timer.

In a further embodiment of the invention, the odor trap by a time-controlled (for example with a periodic interval) working Control realized.

Finally, it should be mentioned that the energy for the proposed washing device from the mains, with mains voltage or low voltage, or from a battery or can be obtained from an alternative source. The electronics can be formed bus or building conductive, in particular for the parameterization of rinsing and cleaning programs and for statistical evaluations.
