Description

The invention relates to a sanitary fitting comprising an outlet.

The invention further relates to a sanitary system with a sanitary fitting.

The invention also relates to a method for operating a sanitary fitting.

Although the present invention is generally applicable to any fluid, the present invention will be explained with respect to water as the fluid.

Sanitary fittings have become known in many different ways. Known sanitary fittings have, for example, a fitting body with at least one actuator for setting at least one property of a fluid flow conducted through the sanitary fitting. The property can be, for example, the flow rate of the fluid stream or the temperature of the fluid stream. In known sanitary fittings, the fluid flow is mixed, for example, from a separate cold water and hot water flow by means of a mixing faucet and is routed from there to an outlet.

To increase the functionality, for example, from the DE 10 2013 000 773 A1 or the DE 10 2013 002 236 A1 a sanitary fitting has become known with at least a first actuating element for setting the temperature and/or quantity of mixed water and with a second actuating element for setting the quantity of hot water. Mixed water and hot water are dispensed via a common outlet in the outlet of the faucet.

To further increase the functionality, for example, from the EP 2 975 185 A1 a sanitary fitting has become known whose outlet has two separately arranged outlets. The first outlet is in the form of a pull-out shower head and is used to dispense mixed water, the second outlet is used to dispense hot water and is fixed in the spout.

The hot water is usually made available in a boiler or the like, which has to be arranged in a base cabinet due to its installation space. This results in a long line from the boiler to the outlet of the sanitary fitting. If, in addition to the hot water, water with a different type of treatment, for example filtered water, can also be dispensed, it is problematic that the line used for this is still filled with water from the previous type of treatment. This must therefore first be rinsed and/or pre-rinsed, which is not very resource-saving, or residual water from the previous type of treatment is first dispensed, which in turn confuses the user. In addition, this can mean that the user always receives a mixture of residual water and his desired type of treatment. If the water of the other type of treatment is to be dispensed in a precisely defined quantity, the remaining water makes it difficult to dispense the desired quantity.

One object of the present invention is therefore to provide a sanitary fitting and a sanitary system which, in a simple, quick and reliable manner, enables treated water to be dispensed, in particular in a predeterminable quantity, while at the same time providing a high level of user comfort. A further object of the present invention is to provide a method for operating a sanitary fitting which can be carried out simply, quickly and reliably and which enables treated water to be dispensed, in particular in a predeterminable quantity, with a high degree of user convenience.

In one embodiment, the present invention solves the above-mentioned objects by a sanitary fitting comprising
an outlet which has at least one outlet, wherein at least one fluid supply line and at least one fluid return line are arranged in the outlet, and wherein
a switching device is arranged, with which on the one hand a fluid connection between at least one of the fluid supply lines and at least one of the fluid return lines can be established and on the other hand a fluid connection between at least one of the fluid supply lines and an outlet.

In a further embodiment, the present invention achieves the above-mentioned objects with a sanitary fitting system comprising a sanitary fitting according to one of Claims 1-8 and a fluid treatment device which is connected to at least one of the fluid supply lines and a control device for controlling the fluid treatment device.

• - Schalten einer Fluidverbindung zwischen zumindest einer der Fluidzuführleitungen und zumindest einer der Fluidrückführleitungen,
• - Beaufschlagen der zumindest einen Fluidzuführ- und Fluidrückführleitung mit einem Fluid, solange bis ein Verbindungsübergang zwischen Fluidzuführ- und Fluidrückführleitung mit dem Fluid beaufschlagt ist,
• - Schalten einer Fluidverbindung zwischen zumindest einer der Fluidzuführleitungen und einem Auslass, und
• - Ausgeben des Fluids mittels der zumindest einen Fluidzuführleitung über den Auslass.

In a further embodiment, the present invention solves the above-mentioned objects by a method for operating a sanitary fitting according to one of Claims 1-8, comprising the steps

• - switching a fluid connection between at least one of the fluid supply lines and at least one of the fluid return lines,
• - Applying a fluid to the at least one fluid supply line and fluid return line until a connecting transition between the fluid supply line and the fluid return line is acted upon by the fluid,
• - switching a fluid connection between at least one of the fluid supply lines and an outlet, and
• - Outputting the fluid by means of the at least one fluid supply line via the outlet.

One of the advantages achieved in this way is that fluid of different types of treatment can be dispensed in a resource-saving, simple and flexible manner. A further advantage is that the amount of a fluid delivery of fluid of different types of treatment can be delivered precisely with a predefinable amount. Another advantage is that reliability is increased and contamination can be avoided. Another advantage is that, for example, rinsing processes and the like are concealed, that is to say they do not take place via the outlet, so that a user is not irritated by the dispensing of rinsing fluid. In addition, such a rinsing process cleans the corresponding lines, so that any contamination that may be present is also removed.

The term "treated fluid" is to be understood in the broadest sense and refers in particular in the claims, preferably in the description, to fluids, in particular liquids, preferably water in the form of tap water from a water supplier or the like, which is additionally in its Properties and/or its composition and/or processing method is changed. For example, treated water can have a high temperature, so-called hot water with a temperature of more than 80 degrees Celsius, a different degree of carbonization, a partially different composition or the like than the water originally provided by the water supplier. The term "treated fluid" is not to be understood in particular as warm or cold water or mixed water, which is usually provided by a water supplier to a single-family house or apartment building through a house connection or the like and whose temperature may be adjusted via a heater or the like.

The term "type of treatment" is to be understood in the broadest sense and refers, in particular in the claims, preferably in the description, not only to the basic type of treatment of a fluid, in particular a liquid, for example whether the water has been carbonated or not, but also to the degree, intensity or concentration of the treatment, for example the intensity of the carbonation. Different types of processing are understood to mean, for example, different degrees of carbonization, for example “still”, “medium” or “classic”. Different types of preparation also include, for example, different temperatures of hot water, water filtered to different degrees, different concentrations of flavor additives or flavorings, for example using granules for coffee, tea 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, in particular, "non-processing". In addition, “type of treatment” is also to be understood as meaning disinfection and/or sterilization of a fluid, so that a hygienically treated fluid is provided.

The terms “fluid supply line” and “fluid return line” are to be understood in the broadest sense and relate in particular in the claims, preferably in the description, to lines for transporting a fluid, in particular a liquid, preferably water. The terms “fluid supply line” and “fluid return line” are not limited to their respective function of supplying or returning a fluid. In particular, a fluid return line can also serve as a fluid supply line with a corresponding connection or a corresponding water path, and a fluid supply line can serve as a fluid return line with a corresponding connection or a corresponding water path. In other words, the terms mentioned serve in particular to describe a fluid path.

The term "fluid processing device" is to be understood in the broadest sense and refers, particularly in the claims, preferably in the description, not only to the provision of a processed fluid, but also includes the provision of separate fluids, such as a storage device for providing a liquid or gaseous disinfectant or the like.

The term "control device" is to be understood in the broadest sense and refers, in particular in the claims, preferably in the description, to a control device and/or a regulating device for devices connected to the "control device".

Other features, advantages, and other embodiments of the invention are described below or will become apparent thereby.

According to a development, the switching device comprises a valve that can be switched in particular electrically, mechanically and/or hydraulically. This enables a simple and inexpensive switching device to provide fluid connections between fluid supply and fluid return lines. Likewise, the valve can alternatively or additionally be designed as a spring-actuated or pressure-actuated valve.

• - Ablauf einer vorgebbaren Zeitspanne,
• - Erreichen einer vorgebbaren Temperatur eines Fluids in einer der Fluidleitungen,
• - Erhalten einer Anforderung mittels einer Anforderungseinrichtung,
• - Erreichen eines vorgebbaren Drucks eines Fluids in einer der Fluidleitungen,
• - Erreichen einer vorgebbaren Durchflussleistung in einer der Fluidleitungen, und/oder
• - Erreichen einer vorgebbaren Durchflussmenge in einer der Fluidleitungen.

According to a further development, the switching device is designed to switch a fluid connection between the fluid supply line and the fluid return line when the fluid connection is switched between the fluid supply line and the outlet, and to close the fluid connection between the fluid supply line and the outlet if at least one of the following conditions is met:

• - Expiry of a specified period of time,
• - Reaching a predetermined temperature of a fluid in one of the fluid lines,
• - receiving a request by means of a requesting device,
• - Reaching a predetermined pressure of a fluid in one of the fluid lines,
• - Reaching a predetermined flow rate in one of the fluid lines, and / or
• - Reaching a predetermined flow rate in one of the fluid lines.

One of the possible advantages is that the fluid can be returned in a simple and at the same time flexible manner, for example in order to prevent a user from noticing flushing processes with a flushing fluid in the lines.

According to a further development, the switching device is arranged adjacent to at least one of the outlets in the outlet. The advantage of this is that during flushing processes, essentially all areas of the fluid supply and fluid return lines can be flushed with a flushing fluid. In general, the switching device can be wired or wirelessly connected to an operating device or control device of the sanitary fitting and can be controlled by means of the operating or control device.

According to a further development, at least two fluid supply lines are arranged, with one of the fluid supply lines serving to dispense cold, warm and/or mixed water by means of the outlet and the at least one other fluid supply line serving to dispense treated water. The advantage of this is flexible operation of the sanitary fitting, so that, for example, mixed water, ie cold and/or hot water, is always and immediately available for a user without having to first remove treated water from the fluid supply line.

According to a further development, the outlet has a number of outlets, in particular one outlet for each fluid supply line. This further increases the comfort for a user since there are separate outlets for tapping different fluids.

According to a further development, the outlet has a pull-out shower head with at least one of the outlets, in particular comprising the outlet for dispensing cold, warm and/or mixed water. One of the advantages achieved in this way is that the operability or flexibility in operation is further increased for a user.

According to a further development of the sanitary fitting system, the fluid treatment device includes at least one of the following devices:

• - a filter device for providing a filtered fluid, in particular filtered water,
• - a carbonation device for providing a carbonated fluid, in particular carbonated water,
• - A heating and/or heating device for providing fluids at high temperatures, in particular hot water,
• - a cooling device, in particular for providing a cooled fluid, in particular water,
• - an ionization device for ionizing a fluid, in particular water,
• - an enrichment device for enriching the fluid with at least one substance, in particular a mineral, flavoring, coloring or the like,
• - an additional device for adding concentrates, in particular fruit juice concentrates or the like to a fluid,
• - a hygiene facility for the provision of hygienically prepared fluid, in particular for the disinfection of a fluid,
• - A cleaning device for providing a cleaning and/or rinsing medium instead of or for adding to a fluid.

The hygiene device can have, for example, an irradiation device for providing UV light or the like. In order to a large number of possible types of treatment for fluids, in particular water, can be made available. These can also be stored, so that they can be dispensed more quickly when the respective processed fluid is selected again.

According to a further development of the sanitary fitting system, the at least one fluid return line can be connected to the fluid treatment device and/or to a fluid discharge outlet, in particular a waste water outlet. On the one hand, this enables, for example, a resource-saving return of treated water that has not been dispensed, and on the other hand, a flushing fluid or a fluid that is no longer suitable for reuse can also be disposed of in a waste water outlet.

• - Ablauf einer vorgebbaren Zeitspanne, insbesondere nach Ablauf einer vorgebbaren Zeit der Inaktivität,
• - Erreichen einer vorgebbaren Temperatur eines Fluids in einer der Fluidleitungen,
• - Erhalten einer Anforderung mittels einer Anforderungseinrichtung,
• - Erreichen eines vorgebbaren Drucks eines Fluids in einer der Fluidleitungen,
• - Erreichen einer vorgebbaren Durchflussleistung in einer der Fluidleitungen, und/oder
• - Erreichen einer vorgebbaren Durchflussmenge in einer der Fluidleitungen.

According to a further development of the sanitary fitting system, the control device is designed to fluidly connect at least one of the fluid supply lines to at least one of the fluid return lines and/or to one of the outlets and to apply a flushing medium if at least one of the following conditions is met:

• - expiration of a predeterminable period of time, in particular after the expiration of a predeterminable period of inactivity,
• - Reaching a predetermined temperature of a fluid in one of the fluid lines,
• - receiving a request by means of a requesting device,
• - Reaching a predetermined pressure of a fluid in one of the fluid lines,
• - Reaching a predetermined flow rate in one of the fluid lines, and / or
• - Reaching a predetermined flow rate in one of the fluid lines.

The advantage of this is that, for example, regular cleaning of the fluid lines is made possible, which increases the service life of the sanitary fitting and enables improved hygiene overall. The wording “as required” is to be understood in the broadest sense and means, for example, that a user can initiate cleaning with a flushing fluid himself, for example by pressing an existing cleaning button or the like. The wording also means that on-demand cleaning occurs when the plumbing fixture is in a certain condition, for example, when the user has selected different types of water in sequence, or the last type of treatment requires rinsing, for example, when the treated fluid is flavored Fluids or the like was tapped.

According to a development of the method, before the at least one fluid supply and fluid return line is supplied with the fluid, the at least one fluid supply and fluid return line is supplied with a flushing fluid. The term “flushing fluid” includes both a cleaning fluid and a sterilizing or disinfecting fluid. The advantage of this is that regular cleaning of the fluid lines is made possible, which increases the service life of the sanitary fitting and enables improved hygiene overall.

According to a further development of the method, the application of rinsing fluid is carried out after a predefinable period of inactivity and/or upon request by a user and/or after dispensing a specific processed fluid and/or before dispensing a fluid. The advantage of this is regular flushing of the fluid lines, which further increases the service life. If, for example, a flavored fluid is dispensed as processed fluid, the rinsing process can be carried out after the corresponding dispensing in order to prevent flavoring residues from settling in the lines. If a flavored fluid has been dispensed, the rinsing process can also be carried out (again) before the flavored fluid or another fluid is dispensed.

According to a further development of the method, the fluid return line is connected to a fluid discharge outlet, preferably a waste water outlet, in particular during the application of flushing fluid. In this way, for example, excess residual water and/or rinsing fluid containing impurities can be disposed of directly.

Further important features and advantages of the invention result from the dependent claims, from the drawings and from the associated description of the figures based on the drawings.

It goes without saying that the features mentioned above and those still to be explained below can be used not only in the combination specified in each case, but also in other combinations or on their own, without departing from the scope of the present invention.

1 shows a sanitary fitting system in a schematic representation according to an embodiment of the present invention.

In 1 a sanitary fitting 1 of a sanitary fitting system 10 is shown in detail. The sanitary fitting 1 has, in the usual way, a fitting body 1' and an outlet 2, which is L-shaped here and which can be rotatably mounted on the fitting body 1'. In the outlet 2, two water supply lines 21, 22 are arranged, which are each connected to an outlet 3, 4. As indicated by the vertical broken line between the two outlets 3, 4, the outlet 2 can be designed as a pull-out shower head 40, one of the outlets 4 then being arranged in the pull-out shower head. Both outlets 3, 4 can have jet formers (not shown).

Furthermore, a switching device 5, here in the form of an electric valve, is arranged in the outlet 2 in the area of the outlet 3, which can be switched by means of a control device 16, so that a fluid connection is established between the second water supply line 22 and a water return line 31 arranged in the outlet 2 or a fluid connection between the second water supply line 22 and the outlet 3 arranged closer to the fitting body 1′. The switching device 5 can be designed in such a way that when the fluid connection is switched between the water supply line 22 and the outlet 3, after a specifiable period of time and/or on request by means of a request device 15, a fluid connection between the water supply line 22 and water return line 31 is switched and the fluid connection between the water supply line 22 and outlet 3 is closed. The request device 15 can be designed as an operating unit for a user, for example as a switch or button. The requesting device 15 can also be connected to the control device 16, which receives signals from the control device 16 and switches the fluid connections mentioned accordingly. The same applies accordingly to a control device 55 for a water treatment device 50 described below.

The first water supply line 21 is used to dispense mixed water, ie cold and/or hot water. For this purpose, the first water supply line 21 is connected to a mixer tap 12 and this in turn is connected to a cold and hot water house connection 11a, 11b. A user can dispense mixed water via the first water supply line 21 and the outlet 4 in the outlet 2 by operating the mixer tap 12 .

The second water supply line 22 is connected to a water treatment device 50 which can be arranged underneath a worktop 90 . The water treatment device 50 comprises a plurality of water treatment modules 51, 52, 53, 54 arranged in an interchangeable manner, here for example the treatment module 51 for the provision of soda, the treatment module 52 for filtered water, the treatment module 53 for hot water with a temperature of more than 90 degrees Celsius and the treatment module 54, which can add cleaning liquid to the water or directly stores cleaning liquid. The water treatment device 50 can be actuated by means of the above-mentioned control device 55, which is connected to corresponding operating elements (not shown) by wire or wirelessly for a user. In order to provide water for treatment by the water treatment device 50, this is connected to the cold water house connection 11a.

As already stated above, the second water supply line 22 is connected to the water return line 31 via the switching device 5 . In the further course, the water return line 31 is connected to a waste water outlet 60 downstream.

The switching device 5 can be designed in such a way that a rinsing process for the second water supply line 22 is carried out as follows. In order to trigger a rinsing process, the switching device 5 is first actuated by one of the control devices 16, 55 in order to establish a fluid connection between the second water supply line 22 and the water return line 31, so that no fluid is dispensed via the outlet 3. The water treatment device 50 is then actuated, so that a cleaning or rinsing medium flows from the treatment module 54 via the second water supply line 22 to the switching device 5 and further into the water return line 31 . The water return line 31 is - as already mentioned - connected to the waste water outlet 60, so that the rinsing or cleaning medium is discharged via this. The water treatment device 50 can then be actuated again, so that the cleaning medium can be removed from the water lines 22, 31, for example by means of filtered water.

The water supply and/or water return lines 21, 22, 31 and/or other lines can be made in the form of flexible hoses, for example made of silicone, polytetrafluoroethylene PTFE and/or polysiloxane, or also be designed as fixed lines made of copper, stainless steel or the like . Furthermore, the water supply and/or water return lines 21, 22, 31 can be thermally insulated from one another and/or from an outer shell of the spout 2 by means of an air cushion and/or by means of insulating material, for example to avoid scalding when hot water is dispensed. Likewise, more than two water supply lines 21, 22 and/or several water return lines 31, generally fluid lines 21, 22, 31, can also be arranged in the outlet 2. In this case, the number m of water supply lines 21, 22 can be, in particular, n+1, where n represents the number of water return lines. Likewise, the number or outlets 3, 4 can be n+1 and/or the number p of switching devices can be n. In the embodiment mentioned 1 is m=2, n=1, o=2 and p=1.

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

In 2 steps of a method for operating a sanitary fitting are shown. The sanitary fitting comprises an outlet which has at least one outlet, at least one fluid supply line and at least one fluid return line being arranged in the outlet and a switching device being arranged with which a fluid connection can be established between at least one of the fluid supply lines and at least one of the fluid return lines and on the other hand a fluid connection between at least one of the fluid supply lines and an outlet.

• In a further step S3, a fluid connection is switched between at least one of the fluid supply lines and an outlet.
• In a further step S4, the fluid is discharged by means of the at least one fluid supply line via the outlet.

3 shows a sanitary fitting system in a schematic representation according to an embodiment of the present invention.

In 3 FIG. 10 is in detail a sanitary fixture system 10 according to FIG 1 shown. In contrast to the sanitary fitting system 10 according to 1 is in accordance with the sanitary fitting system 10 3 A pumping device 42 is now arranged downstream of the water treatment device 50 to increase the pressure of the treated water in the water supply line 22. In particular in connection with the pumping device 42, the switching device 5 can be designed to be pressurized accordingly. If the pump device 42 is not actuated and the treated water in the water supply line has a predeterminable first pressure, the switching device 5 provides, for example, a fluid connection between the water supply line 22 and the water return line 31, for example for rinsing or cleaning purposes. If the pump device 42 is now actuated and the treated water in the water supply line 22 has a second pressure that is greater than the first pressure, the switching device 5 is actuated by the increased pressure in such a way that a fluid connection is established between the water supply line 22 and the outlet 3 is and the fluid connection between water supply line 22 and water return line 31 is interrupted. The treated water is then discharged through outlet 3. If the pressure falls, in particular due to the pump device 42 being switched off, the fluid connection between the water supply and water return lines 22, 31 is in turn switched on and the fluid connection to the outlet 3 is closed.

Furthermore, a second switching device 70 is arranged, with which the second water return line 22 can be connected either to a waste water outlet 60 or to the water treatment device 50 for the return of unused, treated water. For this purpose, the second switching on Device 70 can be connected to the control device 55 of the water treatment device 50 by wire or wirelessly. In addition, the water treatment device 50 can be provided with a distribution device 41 which—if treated water can be used again—according to the type of treatment, returns the unused, treated water returned by means of the water return line 31 to the corresponding water treatment module 51, 52, 53, 54 supplies.

The switching devices 5, 70 can be designed to interact in such a way that a rinsing process for the second water supply line 22 is carried out as follows. In order to trigger a rinsing process, the switching device 5 is first actuated by one of the control devices 16, 55 in order to establish a fluid connection between the second water supply line 22 and the water return line 31, so that no water is dispensed via the outlet 3. The water treatment device 50 is then actuated so that a cleaning or rinsing medium flows from the treatment module 54 via the second water supply line 22 to the switching device 5 and further into the water return line 31 . Depending on the flow rate, which can be specified or measured, for example, the switching device 70 can then connect the water return line 31 to the waste water outlet 60 so that the flushing or cleaning medium is discharged. The water treatment device 50 can then be actuated again and, for example, use filtered water to remove the cleaning medium from the water lines 22, 31. The switching device 70 can then connect the water return line 31 to the water treatment device 50 again, for example as in 1 shown, connect to the treatment module 53 for hot water via the distribution device 41.
