Description

[0001] TITLE

[0002] SANITARY SYSTEM

[0003] TECHNICAL FIELD

[0004] The present invention relates to a sanitary system according to claim 1 and an arrangement with a sanitary system according to claim 18.

[0005] STATE OF THE ART

[0006] Networked sanitary systems are known from the state of the art. For example, DE 93 13 983 U1 discloses a central control system for controlling various sanitary elements.

[0007] PRESENTATION OF THE INVENTION

[0008] Based on this prior art, the present invention is based on the object of providing a sanitary system which has extended functionalities.

[0009] These and other objects are achieved by the sanitary system according to claim 1. The sanitary system comprises a plurality of sanitary elements which have a sanitary element-side communication interface, and at least one gateway which has a gateway-side communication interface, a memory and a processor, wherein the memory and processor are operatively connected to each other and to the gateway-side communication interface,

[0010] The at least one gateway is connected to the sanitary element-side communication interface via a data connection via the gateway-side communication interface. The data connection is designed as a direct data connection. The data connection is configured such that data can be exchanged between the gateway and the sanitary element via the data connection. Depending on the design of the sanitary element, the data exchange can take place bidirectionally or unidirectionally from the sanitary element to the gateway. The gateway's memory is designed to store at least one logical group to which at least one selection from all the sanitary elements connected to the gateway is assigned.

[0011] Storing the logical groups at the gateway level has the advantage that the plumbing system can be scaled as required.

[0012] For example, the plumbing system can be designed as a small plumbing system with only one gateway, with all plumbing elements connected to the gateway. Such a small plumbing system can be used, for example, in a single-family home.

[0013] The plumbing system can also be designed as a larger plumbing system containing multiple gateways. The gateways can be connected to a computer network in an array as described below.

[0014] The group formation provides a further advantage in that each gateway can function independently of other gateways or of higher-level structures, such as the computer network mentioned below, with the sanitary elements connected to the gateway and grouped at the gateway level.

[0015] Group storage at the gateway level has the advantage that fewer data points need to be configured in a larger plumbing system, because the gateway itself provides a data point that already groups the plumbing elements. As explained further below, the gateway can also provide a group of data points. This simplifies the setup of larger plumbing systems because fewer data points need to be configured.

[0016] A direct data connection means that the connection between the gateway and the connected sanitary elements is formed without an intermediate connection with additional electronic components.

[0017] Another advantage of creating groups is that it can improve clarity in larger sanitary facilities. For example, an alarm or fault message from a sanitary element can be displayed together with the corresponding group, which greatly improves on-site findability.

[0018] The expression "at least one selection" means that all sanitary elements connected to the gateway are grouped in the group or that only a selection of all sanitary elements connected to the gateway are grouped in a group.

[0019] Preferably, the processor is configured to group at least one selection from all the plumbing elements connected to the gateway into at least one logical group. This means that the logical group is created directly on the gateway.

[0020] Preferably, the logical group is formed according to the type of sanitary elements and / or according to the placement of the sanitary elements in relation, in particular in local or functional relation, to one another and / or according to the function of the sanitary elements.

[0021] When placing sanitary elements, for example, all sanitary elements in a restroom can be assigned an ascending number. This allows for easier inventory and retrieval.

[0022] When grouping by type of sanitary element, all sanitary elements of the same type can be grouped together. For example, in a larger sanitary room, the following groups can be formed:

[0023] • Urinal group with all urinals connected to the gateway

[0024] • Toilet group with all toilets connected to the gateway

[0025] • Washbasin group with all washbasins connected to the gateway

[0026] Preferably, several logical groups are formed, wherein the several logical groups are combined into a supergroup.

[0027] For example, a supergroup could be a men's restroom, which includes the urinal group, the toilet group, and the vanity group; or a women's restroom, which includes the toilet group and the vanity group. In an apartment building, for example, each apartment can represent a supergroup.

[0028] Preferably, the sanitary element has an identifier, wherein the identifier is assigned to at least one logical group.

[0029] The identifier can, for example, be a serial number and / or a sanitary element designation. The sanitary element designation can include the type of sanitary element, for example, urinal, toilet, or washbasin, and / or a product designation, such as Preda, Selva, Tamina, One, etc.

[0030] Preferably, the assignment to a logical group can be stored exclusively in the gateway, but not at the plumbing element level. In other words, the information regarding the assignment to a group is stored only on the gateway. No corresponding storage takes place on the plumbing element itself.

[0031] Preferably, the processor of the gateway is configured such that the at least one logical group is automatically combined, in particular based on predetermined criteria.

[0032] In a particularly preferred embodiment, the sanitary system further comprises a computer, in particular a mobile computer, wherein the computer has a computer-side communication interface, and wherein the gateway has a further communication interface. A data connection can be provided between the computer-side communication interface and the further communication interface. The computer provides a user interface configured such that a user can perform said grouping manually.

[0033] Preferably, the computer is a mobile phone, a tablet, a notebook, etc. The user interface is typically provided by a screen and corresponding input elements.

[0034] Preferably, the grouping is performed within the direct data connection between the gateway and the plumbing element. This means that the computer only provides the user interface, and the grouping is processed at the gateway level.

[0035] Alternatively, the computer may have a processor configured to group at least a selection of all the plumbing elements connected to the gateway into at least one logical group. The logical group can be transmitted to the gateway as a data set via the data connection between the gateway and the computer. Furthermore, the logical group can be stored in the gateway's memory.

[0036] Preferably, the user interface is configured such that said sanitary elements are displayed on the user interface in such a way that a user can independently group the sanitary elements to be grouped. The grouping is performed by user input.

[0037] Preferably, operating data typical for the sanitary element, such as water consumption and / or number of actuations, are transmitted from the sanitary element to the gateway via the data connection between the gateway and the sanitary elements.

[0038] Preferably, the processor of the gateway is configured such that the operating data of the group can be processed.

[0039] The operational data can therefore be consolidated at the gateway level. For example, it is conceivable that the operational data could be aggregated at the gateway level.

[0040] Preferably, the sanitary element comprises an actuator, wherein the sanitary element control is configured for the intended control of the actuator; and / or wherein the sanitary element comprises a sensor for measuring a physical quantity. The sanitary element control or the sensor comprises the said sanitary element-side control.

[0041] The term "sanitary element" refers to all elements to be placed in a sanitary room. In particular, the term "sanitary element" includes a flush for a urinal or toilet, a sanitary fitting for a washbasin or shower, a flush plate, a mounting frame with an integrated sanitary element actuator, a shower toilet, and / or a shower toilet seat. However, the sanitary element can also be a sensor located in a sanitary room. Thus, environmental data such as air temperature, humidity, user frequency, water temperature, etc. can be recorded by the sensor and evaluated accordingly in the sanitary system.

[0042] Preferably, a plurality of sanitary elements are arranged in a sanitary system.

[0043] After the data connection has been established, the gateway automatically detects the sanitary element(s) connected to the gateway and maintains the data connection.

[0044] Preferably, the sanitary system further comprises at least one input element with a communication interface on the input element side and at least one manually operable actuating element. Upon actuation of the actuating element, a control signal can be transmitted to the gateway via the communication interface on the input element side. The input element is assigned to at least one of the at least one logical group mentioned. The control signal can be processed by the processor in the gateway and made available to the at least one logical group to which the input element is assigned.

[0045] The input element is preferably designed separately from the sanitary items.

[0046] The input element can be designed in various ways. Particularly preferably, the input element is one that can only be activated upon presentation of a valid authorization. For example, the input element is a key switch that can be activated with a key, a code field that can be activated by entering a correct code, or a fingerprint reader that can be activated by recognizing the fingerprint of an authorized person.

[0047] The input element-side communication interface can be connected to the gateway-side communication interface via a data connection. The data connection can be provided in the same way as, or in a similar manner to, the data connection between the sanitary elements and the gateway. Alternatively, the data connection between the input element-side communication interface and the gateway can also be established via the computer network described below. Preferably, each group is assigned its own actuating element. However, it is also conceivable that one actuating element can be provided for several groups.

[0048] Preferably, the control signal represents a switch-on command, in which the sanitary elements assigned to the logical group are switched on; and / or the control signal represents a switch-off command, in which the sanitary elements assigned to the logical group are switched off.

[0049] Preferably, at least one data point can be provided per sanitary element by the sanitary element, wherein the data points can be stored in the memory of the gateway.

[0050] Preferably, a data point is information about a state of the sanitary element, for example the number of flushes or valve openings of the sanitary element.

[0051] Preferably, similar data points from plumbing elements assigned to a logical group can be summarized in a group of data points, assigned to the logical group, and stored in memory in association with the logical group. For example, the number of flushes or valve openings of all plumbing elements in a group can be summarized.

[0052] Particularly preferably, similar data points from multiple logical groups can be combined into one data set and stored in memory. For example, the number of flushes or valve openings of all plumbing elements can be combined into all or several logical groups.

[0053] The arrangement further comprises a computer network, wherein the gateway has a further communication interface via which a data connection can be provided between the gateway and the computer network.

[0054] The computer network can be a cloud structure, a wireless or wired network and / or a building management system.

[0055] Preferably, the gateway provides a data point assigned to the at least one logical group. This data point is made available to the computer network. The gateway and the at least one logical group can be accessed via this data point via the computer network. Integrating multiple gateways offers the advantage that only one data point needs to be configured or connected per gateway, and that this data point is assigned to one or more groups.

[0056] Preferably, the computer network includes a processor configured to group at least a selection of all the plumbing elements connected to the gateway into at least one logical group. Once created, the logical group can be transmitted to the gateway as a data record via the data connection between the gateway and the computer network. The logical group can be stored in the gateway's memory.

[0057] This embodiment has the advantage that an installer with access to the computer network can create and / or control the group formation from a remote position, i.e. not on site.

[0058] Preferably, a plurality of gateways are connected to the computer network, wherein the computer network is configured to exclusively group together at least a selection of gateways from all gateways connected to the computer network in a logical group, but not to group together sanitary elements connected to the gateways.

[0059] Further embodiments are specified in the dependent claims.

[0068] DESCRIPTION OF PREFERRED EMBODIMENTS

[0069] Figures 1 and 2, as well as 3, schematically show an embodiment of a sanitary system of a first embodiment. The sanitary system comprises several sanitary elements 1a, 1b, 1c, 1d, 1e, 1f and at least one gateway 4.

[0070] The sanitary elements 1a, 1b, 1c, 1d, 1e, 1f are shown as examples in the figures. The sanitary element 1a is a cistern with a flush valve as the actuator. The cistern can also have a hygiene flush valve. The sanitary elements 1b and 1c are actuator plates for triggering the flush of a toilet or urinal. The actuator plate 1b here has a detection sensor, and the actuator plate 1c here has an actuation button. The sanitary element 1d is an outlet fitting for a washbasin, and the sanitary element 1e is an outlet fitting for a shower. However, the sanitary element can also be provided by a sensor. Each of the sanitary elements 1a, 1b, 1c, 1d, 1e, 1f has a sanitary element-side communication interface SK1.

[0071] Depending on the design, the sanitary element 1a, 1b, 1c, 1d, 1e, 1f comprises a sanitary element control 2 and an actuator 3, wherein the sanitary element control 2 is configured to control the actuator 3 as intended. The sanitary element can also comprise a sensor for measuring a physical quantity, such as a temperature or a flow rate.

[0072] The at least one gateway 4 comprises a gateway-side communication interface GK1, a memory 5, and a processor 6. The memory 5 and processor 6 are operatively connected to each other and to the gateway-side communication interface GK1. The operative connection is such that the functions described herein can be executed and that data can be processed.

[0073] The at least one gateway 4 is connected via the gateway-side communication interface GK1 to the sanitary element-side communication interface SK1 via a data connection D. Preferably, after establishing the data connection D, the gateway 4 will automatically detect the sanitary element(s) 1a, 1b, 1c, 1d, 1e, 1f connected to the gateway 4 and maintain the data connection D. After detection, the group formation described herein can be performed.

[0074] The data connection D is designed as a direct data connection and is configured such that data can be exchanged between the gateway 4 and the sanitary element 1a, 1b, 1c, 1d, 1e, 1f via the data connection D. The data can be operating data, such as water consumption, number of actuations, or control data.

[0075] The memory 5 of the gateway 4 is designed to store at least one logical group G, to which at least one selection from all the sanitary elements 1a, 1b, 1c, 1d, 1e, 1f connected to the gateway 4 is assigned. Figure 1 symbolizes two groups G. Sanitary elements 1b and 1c are assigned to one group, and sanitary elements 1d and 1e are assigned to the other group. Sanitary element 1a is not assigned to any group. In other variants, it is also conceivable for all sanitary elements connected to the gateway 4 to be assigned to a single group. As explained below, other types of assignment are also conceivable.

[0076] Preferably, the assignment to a logical group G is stored exclusively in gateway 4, but not at the level of the sanitary elements 1a, 1b, 1c, 1d, 1e, 1f. This has the advantage that no data loss results in the event of a sanitary element failure.

[0077] In the embodiment shown, the sanitary system further comprises a computer 7. The computer 7 is, in particular, a mobile computer. The computer 7 has a computer-side communication interface CK, and the gateway 4 has a further communication interface GK2. A data connection can be established between the computer-side communication interface CK and the further communication interface GK2. The computer 7 is connected to the gateway 4 either temporarily or permanently. The computer 7 provides a user interface via which a user can enter inputs.

[0078] The processor 6 of the gateway 2 is preferably configured to combine at least a selection of all sanitary elements 1a, 1b, 1c, 1d, 1e, 1f connected to the gateway 4 in at least one logical group G.

[0079] The grouping can, for example, be carried out by automatic grouping according to predefined rules, which is carried out by the processor 6 itself.

[0080] On the other hand, grouping by a user is also conceivable. Here, it is advantageous if the user can perform the grouping via the user interface of a computer 7. The user interface is configured such that a user can perform said grouping manually. In other words, the user interface is configured such that the said sanitary elements 1a, 1b, 1c, 1d, 1e, 1f are displayed in such a way that a user can independently group the sanitary elements 1a, 1b, 1c, 1d, 1e, 1f to be grouped.

[0081] Via the data connection D between gateway 4 and the sanitary elements 1a, 1b, 1c, 1d, 1e, 1f, typical operating data for the sanitary element 1a, 1b, 1c, 1d, 1e, 1f, such as water consumption and / or number of actuations, are transmitted from the sanitary element 1a, 1b, 1c, 1d, 1e, 1f to the gateway 4. This operating data can then be summarized on the gateway 4 according to the individual groups G.

[0082] Figure 2 shows a sanitary room S1 with various sanitary elements 1f. It contains four toilets, four urinals, and two washbasins. The sanitary elements 1f comprise elements that enable their intended use, such as a cistern with a flush valve and a control element. The sanitary elements 1f are connected to the gateway 4 via the data connection not shown in Figure 2. In the embodiment shown, all toilets are grouped in one group G, all urinals in another group G, and all washbasins in a third group G.

[0083] In addition to the sanitary room S shown in Figure 2, another sanitary room S2 is shown in Figure 3. This additional sanitary room S2 does not have urinals. The toilets in the second sanitary room are grouped together in a group G, and the washbasins are grouped together in another group G. Furthermore, all groups in the first sanitary room S1 are grouped together in a supergroup Z1, and all groups in the second sanitary room S2 are grouped together in a supergroup Z2.

[0084] In Figure 1, the sanitary system is also shown in conjunction with an arrangement: The arrangement comprises a sanitary system 1 as described above and a computer network 10. The gateway 4 has a further communication interface GK3, via which a data connection between the gateway 4 and the computer network 10 can be provided.

[0085] Preferably, a processor is present in the computer network 10, which processor is configured to group at least a selection of all sanitary elements 1a, 1b, 1c, 1d, 1e, 1f connected to at least one gateway 4 into at least one logical group G. The grouping can thus also be performed in the computer network 10. This can be done as a supplement or alternative to the grouping via the computer 7 or on the gateway 4. The logical group can be transmitted to the gateway as a data record via the data connection between the gateway and the computer network, and the logical group can be stored in the memory 5 of the gateway 4.

[0086] The computer network may be connected to a plurality of gateways, wherein the computer network is configured to group together exclusively at least a selection of gateways from all gateways connected to the computer network in a logical group, but not to group together plumbing elements connected to the gateways.

[0087] Figures 4 and 5 show a further embodiment of the sanitary system. This further embodiment comprises the above-described elements of the first embodiment and at least one input element 1. Identical elements are provided with the same reference numerals, and reference is made to the above description.

[0088] The at least one input element 11 has a communication interface EK1 on the input element side and at least one manually operable actuating element 12. The at least one input element 11 is a physical input element that can be manually operated by a user. The input element 11 can be integrated into the sanitary system in various ways. In one variant, the communication interface EK1 on the input element side is connected to the first gateway-side communication interface GK1, just like the sanitary elements 1a-1f. In another variant, the communication interface EK1 on the input element side is connected to the computer network 10, which in turn is connected to the gateway 4. Upon actuation of the actuating element 12, a control signal can be transmitted to the gateway 4 via the communication interface EK1 on the input element side.

[0089] Furthermore, the input element 11 is assigned to at least one of the aforementioned at least one logical group. Figure 4 shows that each logical group is assigned an input element 11. However, it is also conceivable that only one or only some of the logical groups have an input element 11. The control signal from the at least one input element 11 can be processed by the processor in the gateway 4 and can be provided to the aforementioned at least one logical group to which the input element is assigned.

[0090] Preferably, the control signal represents an on or off command. The on command can be used to turn on the sanitary elements assigned to the logical group. The off command can be used to turn off the sanitary elements assigned to the logical group. This type of command is particularly advantageous because a cleaning worker can turn the sanitary elements off and on again as a group for a cleaning process.
