Description

The invention relates to a device for providing a cleaning fluid for manual rinsing, comprising at least one outlet for dispensing the cleaning fluid and/or dissolving fluid, in particular into a basin.

The invention further relates to a method for providing a cleaning fluid.

The invention also relates to a sanitary system, comprising a device for providing a cleaning fluid.

Although applicable to any cleaning fluid, the present invention is explained in relation to a cleaning fluid in the form of a dishwashing liquid dissolved in water.

Although applicable to any dissolution fluid, the present invention is explained in relation to drinking water as a dissolution fluid.

Although applicable to any sink, the present invention will be explained with reference to a kitchen sink sink.

Known kitchen sinks usually have a sink, the drain opening of which can be actuated, for example, with a mechanical actuating element for moving a closure element to close and open the drain opening. Furthermore, known kitchen sinks also have a fitting for providing drinking water, which can be actuated by means of a second mechanical or electrical actuating element. If, for example, dirty dishes are to be cleaned in the sink, warm water is first partially filled into the sink in a known manner and the dishes to be cleaned are placed into the sink filled with warm water, the dirty dishes being soaked in advance if necessary. Then, for example, detergent is applied to a cleaning sponge by applying pressure to a detergent bottle or a manually operated pump mechanism and the sponge is soaked in water. The dishes are then cleaned with this and rinsed with fresh water. The gradually contaminated water collects in the basin and is finally drained through the drain opening by operating the mechanical control element.

The problem here is that the repeated rinsing of cleaned dishes causes the fill level in the sink to rise and, at the same time, the water temperature decreases due to the inflow of water that is not at a suitable temperature and due to the length of time the rinsing process takes in the sink. This results in a lower effectiveness of the detergent dissolved in the water in the basin. In addition, the inflow of more water reduces the concentration of the detergent dissolved in the water in the basin, which also results in less cleaning effectiveness. On the other hand, if the level is above the maximum level, the water flows out over the emergency overflow and pollutes it, as it usually does not have a dirt trap. Another problem is that because the amount of water used to wash the dishes cannot be predicted by a user, the user usually exceeds the optimal or suitable amount of detergent many times over. In other words, the user regularly overdoses on the detergent for the dishwashing process, which is not sustainable.

An object of the present invention is therefore to provide a device and a method for providing a cleaning fluid which avoid an overdose of detergent and at the same time enable easy adaptability to the degree of soiling of dishes during manual washing by hand.

A further object of the present invention is to provide an alternative device and method for providing a cleaning fluid.

The present invention solves the above-mentioned tasks in a device for providing a cleaning fluid for manual rinsing, comprising at least one outlet for dispensing the cleaning fluid and/or dissolving fluid, in particular into a basin, in that
an output cleaning fluid provision device is arranged, comprising at least one container for providing an output cleaning fluid, and that
a solution fluid provision device for providing a solution fluid, in particular water, for the initial cleaning fluid is arranged, and that a control device is arranged, which is designed, in accordance with a specification for the cleaning fluid, in each case a predeterminable amount, type of preparation and / or temporal sequence of the delivery of at least one Dispensing fluid and at least one starting cleaning fluid via the at least one outlet to provide the cleaning fluid.

The present invention also solves the above-mentioned objects with a method for providing a cleaning fluid for manual rinsing by means of the device according to one of claims 1-14, wherein the providing of cleaning fluid in the basin takes place in such a way that, in accordance with a specification for the cleaning fluid, a predeterminable amount, type of preparation and / or time sequence of the delivery of at least one solution fluid and at least one starting cleaning fluid is provided via the at least one outlet for providing the cleaning fluid.

The present invention also solves the above-mentioned objects with a sanitary system comprising a device for providing a cleaning fluid according to one of claims 1-14 and a sanitary fitting that is connected to the device for providing a cleaning fluid.

The term “type of processing” or “type of processing”, especially in relation to the term “processing device”, is to be understood in the broadest sense and, in particular in the claims, preferably in the description, does not only refer to the basic type of processing of a fluid , for example whether the fluid has been carbonized or not, but also the degree, intensity or concentration of the treatment, for example the intensity of carbonization, filtering or the like. Different types of processing mean, for example, different degrees of filtering. Different types of preparation also mean different temperatures of fluid, different water hardness, different pH values, fluid filtered to different degrees, different concentrations of other additives, for example granules or the like, different types of mineralization and different concentrations of the same type of mineralization or the like. The term “type of processing” also includes “non-processing”.

The term “initial cleaning fluid” is to be understood in the broadest sense and refers, in particular in the claims, preferably in the description, to cleaning fluids in concentrated form that must be diluted and/or dissolved in another fluid before their actual use.

The term “dissolving fluid” is to be understood in the broadest sense and refers in particular in the claims, preferably in the description, to fluids that serve to dilute and/or dissolve starting cleaning fluids, for example water, in order to use the starting cleaning fluids, in particular for handwashing or manual rinsing.

The term “cleaning fluid” is to be understood in the broadest sense and refers, in particular in the claims, preferably in the description, to a mixture of one or more starting cleaning fluids that have been dissolved in one or more solution fluids and/or diluted with one or more solution fluids. The specified cleaning of objects is then carried out using the cleaning fluid. For example, if an initial cleaning fluid is a rinsing agent and a solvent fluid mixed water, the cleaning fluid represents a mixture of the mixed water and the rinsing agent.

The term “specification” in relation to the term “cleaning fluid” is to be understood in the broadest sense and refers in particular in the claims, preferably in the description, to an amount of the cleaning fluid, a composition of the cleaning fluid in relation to different starting cleaning fluids and/or a Timing sequence of the provision of different cleaning fluids. A specification for a cleaning fluid can, for example, represent an amount of 500 ml of cleaning fluid for heavily soiled dishes to be cleaned, the cleaning fluid being a 1:2 mixture of two different starting cleaning fluids that are mixed with warm water. It is possible to specify different mixing ratios for the cleaning fluid at different times. In particular, during the cleaning process, for example, the detergent can be dosed at a lower dosage because most of the dishes have already been cleaned.

One of the advantages achieved is that an overdose of initial cleaning fluid, in other words for example dishwashing liquid, is reliably prevented.

In addition to improving sustainability, this can also significantly reduce the costs of using cleaning agents. Another advantage is the high level of flexibility, since, for example, a predetermined amount of cleaning fluid can always be provided depending on the degree of contamination.

Further features, advantages and further embodiments of the invention are described below or become apparent thereby.

• - anhand eines vorgebbaren Verschmutzungsgrades, insbesondere wobei dieser anhand der Trübung des Reinigungsfluids mittels eines Trübungssensors für das Reinigungsfluid ermittelt wird und/oder
• - anhand eines Füllstands des Beckens, insbesondere wobei dieser mittels eines Füllstandsensors ermittelt wird, und/oder
• - einer Temperatur des Reinigungsfluids im Becken, insbesondere wobei diese mittels eines Temperatursensors ermittelt wird,

eine Menge und/oder eine Mischung aus einem oder mehreren Ausgangsreinigungsfluiden und/oder eine zeitliche Reihenfolge der Abgabe von unterschiedlichen Reinigungsfluiden zu ermitteln und auszugeben. Unter der Abgabe von unterschiedlichen Reinigungsmitteln ist ebenfalls eine zeitliche Unterbrechung der Abgabe eines Reinigungsfluids zu verstehen. So kann beispielsweise ein Reinigungsfluid für 10 Sekunden abgegeben werden, für weitere 2 Minuten wird dieses nicht abgegeben und danach wird weiter für 15 Sekunden das Reinigungsfluid abgegeben. Einer der damit erzielten Vorteile ist, dass die Abgabe von Reinigungsfluid hinsichtlich Menge und Zusammensetzung noch weiter im Hinblick auf zu reinigende Gegenstände verbessert werden kann.According to an advantageous development of the invention, the control device is designed

• - based on a predeterminable degree of contamination, in particular this being determined based on the turbidity of the cleaning fluid by means of a turbidity sensor for the cleaning fluid and/or
• - based on a fill level of the basin, in particular this being determined by means of a fill level sensor, and/or
• - a temperature of the cleaning fluid in the basin, in particular this being determined by means of a temperature sensor,

to determine and output a quantity and/or a mixture of one or more initial cleaning fluids and/or a chronological order of delivery of different cleaning fluids. The delivery of different cleaning agents also means a temporal interruption in the delivery of a cleaning fluid. For example, a cleaning fluid can be dispensed for 10 seconds, it is not dispensed for another 2 minutes and then the cleaning fluid is dispensed for another 15 seconds. One of the advantages achieved with this is that the delivery of cleaning fluid can be further improved in terms of quantity and composition with regard to the objects to be cleaned.

According to a further advantageous development of the invention, a processing device, in particular a temperature control and/or filter device, is arranged, which is connected to the control device, wherein the control device is designed, at least depending on the at least one starting cleaning fluid, a predefinable type of processing, in particular to provide temperature adjustment and/or filtering for the solution fluid and/or initial cleaning fluid. The advantage of this is that, for example, a temperature or purity of the cleaning fluid can ultimately be provided at which the cleaning fluid can provide an optimal cleaning effect. This shortens the cleaning time for dirty dishes, for example.

According to a further advantageous development of the invention, a basin for receiving the cleaning fluid is arranged, the basin having a basin drain, and the basin drain of the basin can be opened or closed by means of the control device, in particular where the basin drain is opened when a predeterminable maximum fill level is exceeded and if the filling level falls below a predetermined level, the pool drain is closed. The advantage of this is that automated actuation of the closure of the pool drain is possible. In particular, this means that there is no need to arrange a separate overflow for the pool, which saves costs.

According to a further advantageous development of the invention, the control device has a user interface, in particular comprising a wireless interface, for specifying the cleaning fluid. One of the advantages achieved in this way is that a user can specify or set, for example using an app or the like, the degree of soiling of dishes to be cleaned, the amount of cleaning fluid or the like, so that the control device can then provide appropriate cleaning fluid in a suitable amount. In other words, the user can flexibly configure the cleaning parameters for manually washing dishes by hand according to his specifications and wishes, such as the amount of cleaning fluid or the like.

According to a further advantageous development of the invention, at least two outlets are arranged, with one outlet being provided for dispensing the cleaning fluid into the basin, and a further outlet being provided for dispensing fluid free of output cleaning fluid. These outlets can also be designed as multi-volume channels, so that several liquids can be dispensed separately from one another via one outlet. The advantage of this is that, for example, there is no need for laborious cleaning of an outlet after cleaning fluid has been dispensed if drinking water is to be dispensed afterwards.

According to a further advantageous development of the invention, the control device is designed to close the pool drain when cleaning fluid is dispensed via the at least one outlet or to provide cleaning fluid in the amount and/or type of preparation corresponding to the specification of cleaning fluid when the pool drain is opened. The advantage of this is that the pool drain is automatically closed when manual rinsing is to begin, which minimizes the waste of cleaning fluid, or when the pool drain is open, cleaning fluid is re-dosed into the pool in the appropriate amount, type and composition of initial cleaning fluids, in particular regularly depending on the fill level or the like.

According to a further advantageous development of the invention, the at least one outlet is arranged in the basin and/or above the basin, in particular wherein the outlet is arranged above the basin in a sanitary fitting. The advantage of this is a high level of flexibility with regard to the position of the outlet.

According to a further advantageous development of the invention, the control device is designed as a function of the fill level, as a function of the turbidity of the cleaning fluid and/or as a function of the temperature of the cleaning fluid fluids, to supply cleaning fluid according to a predetermined temperature and/or amount and/or to remove it by operating the pool drain. One of the advantages achieved with this is that, for example, fill level monitoring is made possible using the sensor. The pool drain can be opened or closed depending on specified filling levels or using an app. Another advantage is that the degree of contamination of the cleaning fluid in the pool can be determined based on the turbidity. Based on the determined degree of contamination, the pool drain can then be actuated by means of the control device to remove contaminated cleaning fluid and, after it has been closed again, additional, non-contaminated cleaning medium can also be supplied or resupplied.

According to a further advantageous development of the invention, the user can use the user interface to select an amount of cleaning fluid to be dispensed and/or a degree of contamination of objects to be cleaned, the control device being designed based on the selected amount and/or the degree of contamination To control the output cleaning fluid provision device and/or the solution fluid provision device for providing cleaning fluid. The advantage of this is, for example, a precise dosage of cleaning fluid depending on the degree of contamination of the dishes or the like to be cleaned. In addition, the user experience is improved.

According to a further advantageous development of the invention, a mixing device for mixing solution fluid and the at least one starting cleaning fluid for providing cleaning fluid is arranged via the at least one outlet. The advantage of this is that cleaning fluid can be mixed into a basin of solution fluids and/or initial cleaning fluids directly before being added.

According to a further advantageous development of the invention, the initial cleaning fluid provision device and/or the solution fluid provision device and/or the mixing device has a pump for providing a pressure for the respective fluid. In this way, for example, a spray nozzle for the cleaning fluid arranged in the area of the outlet can be pressurized with cleaning fluid, which enables a reduced amount and a uniform distribution of cleaning fluid in the basin.

According to a further advantageous development of the invention, at least one object detection sensor for detecting objects is arranged within the basin. In this way, a suitable amount and composition of the cleaning fluid can be determined automatically. For example, when detecting glasses, a milder cleaning fluid can be provided, whereas in the case of burnt pans or pots and the like, a stronger cleaning fluid and/or cleaning fluid can be provided over a longer period of time.

According to a further advantageous development of the invention, the at least one outlet is arranged in an opening of the basin and can in particular be moved horizontally, such that the opening is closed when the at least one outlet is not in use. The advantage of this is that there is no need for a spout above the basin, which allows for a space-saving arrangement of the spout. In addition, splashes are avoided when dispensing cleaning fluid.

According to a further advantageous development of the invention, before the cleaning fluid is provided, the pool drain of a pool is closed and/or at least the fill level of the pool is monitored by means of a sensor. One of the advantages achieved with this is that, for example, fill level monitoring is made possible using the sensor. The pool drain can be opened or closed depending on specified filling levels or using an app.

According to a further advantageous development of the invention, the specification for the cleaning fluid is made by a user and/or based on data from at least one sensor, in particular a fill level, temperature and/or turbidity sensor for determining contamination of used cleaning fluid. One of the advantages achieved in this way is that a specification for the cleaning fluid is made possible in a flexible manner and, if necessary, automatically.

In the 1 until 3 a device 1 is shown for providing cleaning fluid in the form of detergent dissolved in water. The device 1 includes a sink 2, which has a sanitary fitting 16 with an outlet 4. In addition, a detergent outlet 5 is arranged in a separately arranged dispenser 19. The detergent outlet 5 is fluidly connected to a water supply 7, two detergent containers 6a, 6b, a detergent device 6 and a mixing device 8. The detergent containers 6a, 6b are each connected to a mixing chamber 8' via a check valve 8a, 8c and a respective line 8b, 8d. The mixing chamber 8 'is connected on the one hand to the detergent outlet 5, and on the other hand to a cold water connection 10 of a house or the like via a water supply 7 which has a heater 7a.

A sensor 11 is arranged in the upper area of the tank wall of the tank 2 and is used to monitor the level of the liquid in the tank 2. The sensor 11 is connected to a control device 9, which automatically opens the pool drain 3 completely or partially above a maximum fill level 15. After the maximum fill level 15 is undershot, the control device 9 can close it again.

In addition, an object detection sensor 18 is arranged, which can detect objects 17 within the basin 2. The object detection sensor 18 is connected to the control device 9. The control device 9 can then, depending on the recognized object 17, determine a corresponding amount of detergent and / or a mixture of different detergents from the containers 6a, 6b, which are used to clean the recognized object 17 together with a determined amount of water, which is used by means of the heating device 7a has been heated to a suitable temperature for cleaning is required. In particular, this avoids an overdose of detergent, and at the same time an optimized cleaning of the detected object 17 by hand can be made possible.

The control device 9 has a user interface 9a, which can be connected to a cell phone 100 by means of a wireless interface 9b, for example a WLAN and/or Bluetooth interface. Via the user interface 9a, a user can, for example, freely select the maximum fill level he wants within certain limits. The user can also use the user interface 9a to select the amount of water required for cleaning and/or the desired detergent or confirm the detergent or detergent mixture suggested by the control device 9. Likewise, the user can also use the user interface 9a to enter the degree of contamination of the object 17 to be cleaned, so that the control device 9 selects a suitable detergent mixture and a suitable temperature depending on the degree and/or type of contamination and/or type of object 17 to be cleaned and/or can provide a suitable amount of water mixed with detergent to clean the objects.

In addition, it is also possible for the object recognition sensor 18 to recognize a user's hand and for the control device 9 to accordingly output lukewarm water mixed with an appropriate amount of soap so that the user can wash their hands.

Alternatively or additionally, an outlet 5a can also be retractable in an opening 2a in the wall of the pool 2 - as in 2 shown - arranged. This can be extended and retracted by means of an actuator, for example a bending transducer or - as shown here - an electric motor 14. The outlet 5a can also be designed to be spring-loaded, so that it can be operated by means of appropriate fluid pressure is extended and closed again when delivery is completed due to the spring force.

The outlet 5a is - as in 2 shown - arranged on an underside of a T-shaped closure 12, which can be extended and retracted in the horizontal direction 13. This can have a spray nozzle (not shown). The vertical part of the closure 12 is formed by a substantially vertically oriented cover plate 12a, which closes the opening 2a in a fluid-tight manner relative to the basin 2.

4 shows steps of a method according to an embodiment of the present invention.

• - Auswählen S1 der Funktion „Handspülen“ mittels der Nutzerschnittstelle 9a der Steuereinrichtung 9,
• - Schließen S2 des Beckenauslaufs 3 im Becken 2 mittels der Steuereinrichtung 9,
• - Aktivieren S3 einer Füllstandüberwachung des Beckens 2 mittels zumindest eines Füllstandsensors 11,
• - Erkennen S4 von Objekten 17 im Becken 2, insbesondere Ausfahren des versenkbaren Auslaufs 5a,
• - Abgeben S5 von temperiertem Leitungswasser und/oder von zuvor behandeltem Wasser, vermischt mit Spülmittel, in das Becken 2. Das entsprechende Wasser fließt hierbei gemäß 3 durch die Mischeinrichtung 8. In dieser wird ein für den Handspülprozess geeignetes Spülmittel aus den Behältern 6a, 6b abgegeben und dem Wasser beigemischt und über die vorhandenen Leitungen mittels Leitungsdruck und/oder mittels Pumpe zum Auslass 5a gefördert. Die Zugabe der Spülmittel in der Mischeinrichtung 8 erfolgt zeitnah nach dem ersten Schritt S1. Hierdurch wird durch das nachströmende Wasser ein Freispülen beziehungsweise eine Reinigung der Leitungen gewährleistet. Allgemein ergibt sich somit zu Beginn der Abgabe ein Mischverhältnis von Lösungs- oder Neutralfluid und Ausgangsreinigungsfluid als Reinigungsfluid, welches eine hohe Konzentration des Ausgangsreinigungsfluids aufweist. Die Konzentration des Spülmittels wird mit weiterem Wasserdurchfluss reduziert. Innerhalb der Mischeinrichtung 8 wird die Temperatur und die Durchflussmenge des Wassers ermittelt. Ist der definierte und eventuell vom Nutzer zuvor festlegbare Füllstand des Beckens 2 erreicht, wird dieser vom Füllstandsensor 11 erkannt und die Abgabe von Wasser mittels entsprechender Signale der Steuereinrichtung 9 gestoppt. Steigt der Füllstand im Zuge des Spülprozesses auf ein definiertes, maximales Maß 15 an, wird dies anhand des Füllstandsensors 11 erkannt und die Steuereinrichtung 9 öffnet nun den Beckenauslass 3 solange, bis der maximale Füllstand 15 wieder unterschritten wird.
• - Ganz oder teilweises Ablassen S6 der Wasser-Spülmittelmischung im Becken 2 auf Anforderung des Nutzers.

The process can include one or more of the following steps:

• - Selecting S1 of the “handwashing” function using the user interface 9a of the control device 9,
• - Closing S2 of the pool outlet 3 in the pool 2 by means of the control device 9,
• - Activating S3 a level monitoring of the pool 2 by means of at least one level sensor 11,
• - Detecting S4 of objects 17 in the basin 2, in particular extending the retractable spout 5a,
• - Dispense S5 of tempered tap water and/or previously treated water, mixed with dishwashing liquid, into basin 2. The corresponding water flows accordingly 3 through the mixing device 8. In this, a detergent suitable for the handwashing process is dispensed from the containers 6a, 6b and mixed with the water and conveyed to the outlet 5a via the existing lines using line pressure and/or a pump. The detergent is added to the mixing device 8 shortly after the first step S1. This ensures that the water flowing in ensures that the pipes are flushed or cleaned. In general, at the beginning of delivery, there is a mixing ratio of solution or neutral fluid and starting cleaning fluid as cleaning fluid, which has a high concentration of the starting cleaning fluid. The concentration of the detergent is reduced as the water flows further. The temperature and the flow rate of the water are determined within the mixing device 8. If the defined fill level of the basin 2, which may be predetermined by the user, is reached, this is detected by the fill level sensor 11 and the delivery of water is stopped by means of corresponding signals from the control device 9. If the fill level rises to a defined, maximum level 15 in the course of the rinsing process, this is detected using the fill level sensor 11 and the control device 9 now opens the basin outlet 3 until the maximum fill level 15 is undershot again.
• - Completely or partially draining S6 of the water and detergent mixture in basin 2 at the user's request.

Steps S4 and S5 can in particular be run through iteratively over time. The pool drain 3 is always open in its rest position via a forced device, whereby additional overflow protection is provided if necessary. The occurrence of foam in the cleaning fluid can be reduced by appropriately designing supply lines, since the amount of cleaning fluid and its composition can be adjusted depending on the filling of the basin 2, the dishes present. The detection of the fill level also includes, in particular, the detection of foam.

Alternatively, the cleaning fluid can also be dispensed via the soap outlet 5 or via a hose line guided separately in the fitting body of the sanitary fitting 16.

5 shows a schematic representation of a method for determining a specification for cleaning fluid according to an embodiment of the present invention.

In 5 Steps of a method for specifying 200 a cleaning fluid in a sink are shown in schematic form. The specification 200 for the cleaning fluid includes the volume of the cleaning agent, the type of cleaning agent and/or the temporal sequence of cleaning agent additions. The specification 200 is calculated using a control device 101. For this purpose, the control device 101 uses, on the one hand, the water volume 102 in the basin, which is based on a measured water drain 129 of a drain 114, a predeterminable water volume 120 and information about objects to be cleaned arranged in the basin using object recognition 121. The water in the pool is provided by a central unit 115, which mixes cold water 111 and hot water 110 according to the predetermined amount of water 120 and a predetermined temperature 122. This also determines the water quality 112 and transmits this information to the control device 101. The temperature of the water provided is measured (reference number 123) and the temperature in the pool is also calculated - reference number 103 - using a temperature sensor 124 on or in the pool. In addition, in the drain 129 or in the basin a turbidity of the water 127 can be measured, the value of which is also transmitted to the control device 101. If a user 126 does not specify a degree of contamination 113 of the dishes to be cleaned, a standard setting 125 for the degree of contamination can be used by the control device 101. Alternatively, the degree of contamination can be entered manually 128 and transmitted to the control device 101.

6 shows a schematic representation of a method for determining a specification for cleaning fluid according to an embodiment of the present invention.

In 6 Steps of a method for specifying 200 a cleaning fluid in a sink are shown in schematic form. The specification 200 for the cleaning fluid includes the volume of the cleaning agent, the type of cleaning agent and/or the temporal sequence of cleaning agent additions. The specification 200 is calculated using a control device 101.
