Description

The invention relates to a method for cleaning a recycling shower, a recycling shower that can be cleaned accordingly, and a computer program for controlling a cleaning cycle. A recycling shower is understood to be a shower in which used water can be reused by collecting it via a drainage device of the recycling shower and (re)feeding it to at least one showerhead of the recycling shower. The method provides a particularly advantageous cleaning process for a recycling shower.

In conventional recycling showers, the used water is pumped in a kind of cycle and is therefore also referred to as circulating water. The circulating water is used to reuse water that has already been used for cleaning the body. However, the use of circulating water in a shower usually also means that substances washed off the body (sweat, skin flakes and the like) and also care products for cleaning the body get into the hydraulic system of the system (pipes, water pump, shower head and the like). The presence of these substances can represent a source of food for bacteria, which can also be pumped into the shower area due to the circulation of the used water. In order to reduce such contamination, it has already been suggested that the circulating water itself be cleaned, for example by filtering it or disinfecting it with substances or external influences such as UV radiation. However, appropriate measures for cleaning the circulating water do not yet represent a sufficiently sustainable way of preventing bacterial contamination of the circulating water.

One object of the invention is to at least partially solve the problems described with reference to the prior art. In particular, a method is to be specified which allows an advantageously sustainable possibility for reducing or avoiding bacteria in a recycling shower.

This object is achieved with a method and a recycling shower according to the features of the respective independent patent claims. Further advantageous embodiments of the invention are specified in the dependent patent claims. It should be noted that the features listed individually in the dependent patent claims can be combined with one another in any technologically reasonable manner and define further embodiments of the invention. In addition, the features specified in the patent claims are specified and explained in more detail in the description, with further preferred embodiments of the invention being presented.

1. a) Führen von Wasser über mindestens einen ersten Wasserweg der Recycling-Dusche hin zu der Ablaufeinrichtung, wobei sich der erste Wasserweg zwischen einer Frischwasserquelle und der Brause erstreckt,
2. b) Betätigen eines Spülwasserventils der Recycling-Dusche, um Wasser in eine Ansaugkammer der Ablaufeinrichtung zu leiten, wobei das Spülwasserventil die Durchströmung einer Spülwasserleitung steuert, die sich zwischen der Frischwasserquelle und der Ablaufeinrichtung erstreckt,
3. c) Führen von Wasser über mindestens einen zweiten Wasserweg der Recycling-Dusche hin zu der Ablaufeinrichtung, wobei der zweite Wasserweg durch die Ansaugkammer der Ablaufeinrichtung verläuft.

This is achieved by a method for cleaning a recycling shower in which used water can be reused by collecting it via a drainage device of the recycling shower and feeding it to at least one shower head of the recycling shower, comprising at least the following steps:

1. a) guiding water through at least a first water path of the recycling shower to the drainage device, the first water path extending between a fresh water source and the shower,
2. b) actuating a flush water valve of the recycling shower to direct water into a suction chamber of the drain device, the flush water valve controlling the flow through a flush water line extending between the fresh water source and the drain device,
3. c) guiding water via at least a second water path of the recycling shower to the drainage device, wherein the second water path runs through the suction chamber of the drainage device.

To carry out the method, steps a), b) and c) can be carried out, for example, at least once and/or repeatedly in the order given. Furthermore, steps a), b) and c), in particular steps b) and c), can be carried out at least partially in parallel or simultaneously. The method can be carried out, for example, using a recycling shower described here. The method can be carried out, for example, using a computer program described here.

The method advantageously describes a cleaning process that results in the food source for bacteria in the water-carrying elements of the recycling shower (hydraulic system of the shower) being kept as small as possible or even being completely prevented or removed. In particular, at the request of the user and/or in a time-controlled process, a cleaning process can be carried out following a shower using reuse of previously used water in a specific sequence. The cleaning process can deprive the bacteria in the pipe system of their food source in the form of skin flakes, soaps and other substances. By flushing and optionally subsequently blowing out the pipes of the circulating water system, It is advantageous to ensure that the subsequent user can be offered a system that is as clean as possible, without any residues from previous use.

The recycling process of the recycling shower is generally carried out in such a way that water discharged from the at least one shower is collected and then reused by collecting it via a drainage device of the recycling shower and feeding it back to at least one shower of the recycling shower. The drainage device can, for example, form a floor drain or a wall drain. The drainage device can, for example, be formed in or on a shower tray. In particular in the case of a walk-in shower (without a shower tray), the drainage device can be formed by means of a drainage channel or connected to it. The at least one shower can, for example, comprise an overhead shower and/or a wall shower and/or a hand shower. The used water can be circulated within the hydraulic system of the shower. In step a), fresh water in particular can be fed via the first water path. The first water path can be formed by means of a fresh water line. A fresh water valve can be arranged in the fresh water line. The flush water line can form a bypass to the first water path and/or the fresh water line. The second water path can be formed by means of the flush water line and a recycling water line. Furthermore, the second water path can also be formed in sections by the suction chamber.

The method can further comprise actuating a drain valve to control the drainage of water from the drainage device. The method or a cycle of the method can begin with closing the drain valve, in particular to cause water to build up in the drainage device. The drain valve can be opened as needed or specifically during the method and closed again if necessary. The drain valve can be arranged on the drainage device. The drain valve can be arranged between at least one chamber of the drainage device and a sewage system.

In step c), water can be pumped from the suction chamber of the drainage device to the shower. The pumping can be done by means of a pumping device of the recycling shower. The pumping device can comprise one or more pumps. In particular, water accumulated in the suction chamber can be pumped. The pumping from the suction chamber can cause water to circulate in the recycling shower. In particular, at the end of a cleaning cycle, air can be pumped by means of the pumping device in order to remove water residues from the pipe system or at least part of the water paths, in particular the recycling pipe.

The method can further comprise separating the suction chamber from a collection chamber of the drainage device. The used water or water discharged from the shower can enter the drainage device via the collection chamber. The collection chamber can, for example, be arranged (in terms of flow) between a shower area and the suction chamber. In principle, the suction chamber and the collection chamber can be connected to one another (in terms of flow). This connection can advantageously be separated or prevented if required. The suction chamber of the drainage device can, for example, also be formed by part of the conveyor device, such as by means of a suction container of the conveyor device. The suction container of the conveyor device is in this case arranged on the collection chamber of the drainage device and can be or is connected to it in terms of flow, whereby this connection can be interrupted or separated if required.

In particular, the separation can be carried out by a controlled change in the position of a separating element of the discharge device. The separating element can be a slide valve, for example, which can be lowered to prevent backflow from the suction chamber into the collection chamber. The separating element can (alternatively) be formed by a valve body of a valve that can control the flow through a connecting channel between the collection chamber and the suction chamber.

The process can be carried out automatically by the recycling shower as needed or at predetermined times. The need can be, for example, the need of a user. For example, the cleaning cycle can be selected or initiated by a user of the shower, for example via a user interface of the shower (for example by pressing a button). Alternatively or cumulatively, the cleaning cycle can be automatically initiated and/or carried out in a time-controlled manner at predetermined times, for example after each shower or after a predetermined number of showers. Furthermore, it is also advantageously possible to control and/or set a cleaning cycle or set an automated cleaning plan using application software (app) on a mobile device (smartphone) that can be connected to a control unit of the recycling shower.

Furthermore, it can be provided that the conveying device continues to run after the fresh water supply has ended so that air is conveyed to empty or blow out at least part of the pipe system, in particular the recycling water pipe. This can advantageously contribute to increasing hygiene and/or reducing the formation of germs in the recycling shower.

The solution presented here and its technical environment are explained in more detail below using the figures. It should be noted that the invention is not intended to be limited by the exemplary embodiments shown. In particular, unless explicitly stated otherwise, it is also possible to extract partial aspects of the facts explained in the figures and combine them with other components and/or findings from other figures and/or the present description. It shows schematically:

• 1 : an example of a recycling shower described here in a cross-sectional view.

1 shows a schematic example of a recycling shower 1 described here. In the recycling shower 1, used water can be reused by collecting it via a drain device 2 of the recycling shower 1 and feeding it to a shower head 3 of the recycling shower 1. A single drain device 2 is shown here as an example, but in principle one or more drain devices 2 can be present. The drain device 2 can be in a floor of the recycling shower 1 or in a lower area of a Wall of the recycling shower 1. The drainage device 2 serves to collect used water. For this purpose, the drainage device 2 can be designed in the manner of a container and/or have one or more chambers. At least the drainage device 2 has a suction chamber 12. Collected water can be removed from the suction chamber 12 for reuse for showering, in particular sucked in, for example via a conveyor device 22.

As an example, a single shower 3 is shown here as a head shower or shower head; in principle, one or more showers 3 can be provided, such as a head shower and/or a wall shower and/or a removable hand shower. The used water can be conveyed in a type of circuit, so that it can also be referred to here as circulating water. The at least one shower 3 serves to discharge water into a shower area 10 of the recycling shower 1. The shower area 10 describes in particular the area in which a person or a user can stay to shower.

The recycling shower 1 also has a fresh water valve 11 for controlling the flow through a fresh water line 21 that extends between a fresh water source 5 and the shower 3. The fresh water source 5 is, for example, a mixer for mixing cold water and hot water to a desired mixed water temperature that can usually be set by a user. The cold water can be provided by a cold water connection 16 and the hot water by a hot water connection 17. The fresh water source 5 shown is merely an example. In principle, the fresh water source 5 can also be formed by means of an alternative type of water supply, such as a (fresh) water tank.

The recycling shower 1 also has a flushing water valve 6 for controlling the flow through a flushing water line 7, which extends between the fresh water source 5 and the drainage device 2. The flushing water line 7 represents in particular a bypass or a bypass line for bypassing the first water path 4 or a fresh water line 21, which connects the fresh water source 5 (directly) to the shower 3. Basically, the flushing water is (pure) water. However, it is also conceivable to add a detergent to the flushing water if necessary.

The recycling shower 1 further comprises a conveying device 22 for conveying water from the suction chamber 12 to the shower 3. The conveying device 22 can comprise one or more pumps, for example. The conveying device 22 can be arranged in a recycling water line 20 or can be fluidically connected to it. The recycling water line 20 preferably extends between the drainage device 2 and the shower 3, in particular from the suction chamber 12 of the drainage device to the shower 3. The shower 3 can thus have at least two inlets, namely via the recycling water line 20 and via the fresh water line 21. These inlets can be connected to the shower 3 separately from one another, for example. However, it is also conceivable that the recycling water line 20 and the fresh water line 21 are brought together upstream of the shower 3. The outlets of the shower 3 can also be separated from one another, for example, as shown in 1 shown, at least one fresh water outlet 18 and at least one separate recycling water outlet 19 are provided. In this case, the associated water channels can, for example, run separately through the shower 3. However, it is also conceivable that a mixing chamber is provided in the shower 3, in which fresh water and recycling water can be mixed with one another.

The recycling shower 1 also has a drain valve 13 for controlling the drainage of water from the drainage device 2. The drain valve 13 can, for example, be arranged on the drainage device 2. In principle, the drain valve 13 can also be arranged between the drainage device 2 and a wastewater system external to the shower. The drain valve 13 can be closed in particular for the purpose of causing water to build up in the drainage device 2. The drainage device 2 can, for example, have a controllable separating element 14 which is arranged and set up to separate the suction chamber 12 from a collecting chamber 15 of the drainage device 2 as required. The collecting chamber 15 can, for example, be arranged (in terms of flow) between the shower area 10 and the suction chamber 12. The collecting chamber 15 can, for example, be formed by means of a shower tray or form a drain from the shower tray. In particular, if no shower tray is provided, such as in a walk-in shower, the collecting chamber 15 can form, for example, the front part of a drain channel or a drain insert or a wall drain, viewed along the flow path. It is also conceivable that the collecting chamber 15 is arranged (immediately) downstream of a floor drain opening or a wall drain opening.

The recycling shower 1 can be set up in particular to carry out a method presented here. The method can, for example, comprise guiding water via at least a first water path 4 of the recycling shower 1 to the drainage device 2, wherein the first water path 4 extends between a fresh water source 5 and the shower 3. Furthermore, the method can comprise actuating a flushing water valve 6 of the recycling shower 1 in order to guide water into a suction chamber 12 of the drainage device 2, wherein the flushing water valve 6 controls the flow through a flushing water line 7 which extends between the fresh water source 5 and the drainage device 2. Furthermore, the method can comprise guiding water via at least a second water path 8, 9 of the recycling shower 1 to the drainage device 2, wherein the second water path 8, 9 runs through the suction chamber 12 of the drainage device 2.

The first water path 4 can be formed at least in sections by the fresh water line 21. At least a part of the second water path 8, 9, in particular a front section of the second water path 8, can be formed by the flushing water line 7. At least a part of the second water path 8, 9, in particular a rear section of the second water path 9, can be formed by the recycling water line 20.

• Das Ablaufventil 13 (z.B. eines (Wand-) Ablaufs für das Abwasser) ist geöffnet, jeglicher Eintrag von Frisch- oder Umlauf- bzw. (Recycling-) Wasser über die Brause 3 (Duschkopf) wird unterbunden.
• Das Wasser des gesamten Duschsystems ist nach einer Zeitdauer T1 abgelaufen.

The following describes a particularly advantageous embodiment of a cleaning cycle that can be carried out using the described method or using the described recycling shower 1:

• The drain valve 13 (e.g. of a (wall) drain for waste water) is open, any entry of fresh or circulating or (recycled) water via the shower 3 (shower head) is prevented.
• The water from the entire shower system has drained away after a time period T1.

The fresh water valve 11 is opened in order to supply fresh water to the shower 3 via the fresh water line 21. The fresh water line 21 here represents a first water path 4 or a separate water path to the overhead shower. The fresh water valve 11 is opened, for example, for a period of time T2. The fresh water flows from the shower 3 into the shower area 10. The fresh water is used to clean the shower cubicle, in particular the floor, of substances, foam or the like. The water runs off via the drainage device 2, in particular via the collection chamber 15 and the open drainage valve 13. This is an example of how and, if appropriate, how water can be guided via at least one first water path 4 of the recycling shower 1 to the drainage device 2 according to step a), the first water path 4 extending between a fresh water source 5 and the shower 3.

After that, or subsequently, the drain valve 13 is closed. The fresh water flowing in from the shower 3 is then used to clean at least part of the drain device 2, in particular a drain container formed by the collection chamber 5 and possibly also the suction chamber 12. This also represents an example of actuating a drain valve 13 to control the drainage of water from the drain device 2.

In addition, the flushing water valve 6 is opened and fresh water is fed into the suction chamber 12 or a suction container of the conveying device 22 (pump), which forms the suction chamber 12 of the drainage device 2. Since the conveying device 22 is (still) switched off, the water also reaches the collection chamber 15 of the drainage device 2, which here forms a drainage container, in the form of a flushing stream that is suitable for cleaning the walls of the collection chamber 15. This is an example of how and if necessary how a flushing water valve 6 of the recycling shower 1 can be actuated in accordance with step b) in order to direct water into a suction chamber 12 of the drainage device 2, the flushing water valve 6 controlling the flow through a flushing water line 7 that extends between the fresh water source 5 and the drainage device 2.

After that or subsequently, the drain valve 13 is opened again. The flushing water valve 6 is also closed after a time period T3 has elapsed. Any substances still present in the collection chamber 15 are flushed out.

The drain valve 13 is opened again after a time period T4. The flushing water valve 6 is opened again. The separating element 14, here for example a slide, separates the collection chamber 15 from the suction chamber 12. For this purpose, the slide is moved for example to the lower, closed position. Clean water or fresh water is accumulated in the suction chamber 12.

This represents an example of how and if necessary how the suction chamber 12 can be separated from a collection chamber 15 of the drainage device 2. In particular, this represents an example of how and if necessary how the separation can be carried out by a controlled change in position of a separating element 14 of the drainage device 2.

Then the conveying device 22 (here pump) is switched on and sucks the water out the suction chamber 12 and conveys it via the separate water path formed by the recycling water pipe 20 to the shower 3, from which it exits in the direction of the shower area 10. The pipe system for the circulating water and, if applicable, the connected components are flushed for a period of time T5.

This represents an example of how, and if applicable, how, according to step c), water can be guided via at least one second water path 8, 9 of the recycling shower 1 to the drainage device 2, wherein the second water path 8, 9 runs through the suction chamber 12 of the drainage device 2. In addition, this represents an example of how, and if applicable, how, in step c), water can be conveyed from the suction chamber 12 of the drainage device 2 to the shower 3.

The water introduced into the shower area 10 from the recycling water line 20 is drained via the collection chamber 15 and the drain valve 13 and is not sucked in again by the conveyor device 22. This ensures that the recycling water line 20 is only flushed with clean water.

In other words, this can also be described as fresh water being fed into the suction chamber 12. The closed slide (separating element 14) means that the collection chamber 15 remains (initially) empty. The pump or conveying device 22 sucks the fresh water out of the suction chamber 12 and uses it to flush the circulating water line or recycling water line 20. The water comes out of the shower head or shower 3 (in particular the openings of the fresh water outlet 18) and ends up in the shower tray. From there, it flows out of the system via the drain or drainage device 2.

After that, or subsequently, the flushing water valve 6 is closed. The conveying device 22 now sucks in the remaining water from the suction chamber 12. After a certain period of time T6, the conveying device 22 only sucks in air, which is used to blow out as much of the remaining water in the pipe system, in particular in the recycling water pipe 20, from the shower 3 via the rear section of the second water path 9. After the time T7 has elapsed, the conveying device 22 is switched off again.

The blowing out described can advantageously contribute to the most complete emptying or evacuation of the lines, in particular the recycling water line 20. Blowing out also serves in particular to prevent stagnant water. Germ formation can be greatly reduced in dry environments, while moist environments or standing water can encourage germ formation. Blowing out therefore also represents an advantageous hygiene measure.

The floor of shower 1, the drain, and the piping system for the recycled water operation are then advantageously completely rinsed with fresh water and are (almost) free of water after completion of the cleaning process.

The times T1 to T7 are system and component-dependent times and can be adapted to the existing conditions on site by the operator or installer, for example.

The process can be carried out automatically by the recycling shower 1 as required or at predetermined times. For example, the cleaning process can be controlled and/or triggered manually or automatically when required by a user. For example, it can be carried out manually by a user at the touch of a button or automatically at a time. Controlling, operating and/or setting the cycle via an app can also be advantageous.

Thus, a method can be specified which allows an advantageous sustainable possibility for reducing or avoiding bacteria in a recycling shower.
