The present invention relates to a fitting for a sanitary installation, in particular with adjustable sanitary elements.
Fittings with infrared sensors, capacitive sensors or temperature sensors are known from the prior art, in which the sensor signal is used to control a sanitary element, such as a tap or a toilet flush. This type of sensor can only be used to a limited extent. For example, in the case of an infrared sensor, the beam path between the source and the sensor must be interrupted in order to be able to generate a corresponding signal, as a result of which the arrangement of the sensor, e.g. in the case of a tap, must be located directly at the outlet. Capacitive sensors are temperature sensitive, which leads to different signals at different temperatures in the same situation. By definition, temperature sensors are temperature sensitive. In addition, these sensors can only monitor a small area, i.e. they can only be used very locally.
An object of the present invention is to provide a fitting for a sanitary installation which is insensitive to temperature and with which larger areas can be monitored.
This object is achieved by a fitting with the features of claim 1. Further embodiments of the fitting, a fitting arrangement, and a method for changing a setting of a sanitary element of a fitting according to the invention are defined by the features of further claims.
A fitting according to the invention for a sanitary installation comprises a control unit and at least one sanitary element which can be controlled by the control unit. The fitting comprises at least one vibration detector for detecting ambient vibrations, the at least one vibration detector being connected to the control unit via a data channel, the settings of the at least one sanitary element being changeable on the basis of the ambient vibrations. Vibration detectors are robust detectors that work reliably and have a low susceptibility to interference. Such detectors can detect sound and convert it into an electrical signal. Structure-borne sound or sound that has been transmitted through the air can be detected.
In one embodiment, the at least one vibration detector is a piezoelectric detector or a strain gauge. These detectors are commercially available and are accordingly readily available and inexpensive.
In one embodiment, the fitting comprises two, three or more sanitary elements. It is possible to detect several different vibrations with one detector and to evaluate them with a control unit. This allows the control of several sanitary elements. For example, a detector can detect that a user wants to change the settings of a particular sanitary element.
In one embodiment, at least one supply line is connected before the at least one sanitary element and at least one discharge line after the at least one sanitary element. This allows a flexible combination of the lines with the sanitary elements. For example, several supply lines can each comprise a sanitary element and the respective discharge lines open into a common discharge line. The respective sanitary elements can be controlled separately or simultaneously.
In one embodiment, the fitting comprises two, three or more vibration detectors. With several detectors, more complex vibrations can be recorded and evaluated. It is possible to recognize that a user not only wants a simple on/off of a sanitary element, but that he desires a discreet or continuous change in a setting of the sanitary element. Such a change in the settings of the sanitary element can be initiated with the control unit.
In one embodiment, the at least one vibration detector is arranged on the at least one line and/or on the at least one sanitary element, or the at least one vibration detector is arranged at a distance from the at least one line and/or from the at least one sanitary element. Both variants have their advantages. If the vibration detector is arranged on the line or on the sanitary element, the detector can pick up the body vibrations which are transmitted through the line or through the sanitary element. The structure-borne sound is only weakly damped during transmission. If the detector is arranged at a distance from the lines and/or the sanitary elements, less space is required in the area of the lines or sanitary elements. This is advantageous in tight spaces.
In one embodiment, the sanitary element can be selected from the group comprising a valve, a pump and a fan. A valve can be, for example, a valve for liquids, such as water, disinfectant liquid or soap, or one for gas, such as air. Pipes for cold water, hot water, boiling water, mineral water or other drinks, each with its own valve, can be provided, each valve being able to be opened or closed by the control unit. It is also possible to further open a valve that is already slightly open or to close it a little more. It is also possible that a valve can be opened triggered by a user and the control unit automatically closes the valve automatically after a predetermined time. Different times can be stored in the control unit for different media. If the sanitary element is a pump, a liquid can be actively pumped out of a container. These can be drinks, disinfectants or soaps, for example, filled into containers. The activation of the pump is initiated by a user. The deactivation can also be user-specific, or it can be carried out by the control unit. The same applies to the case when the sanitary element is a fan or a ventilator. Instead of a liquid, a gas, such as air, is pumped. It is also possible to activate a heating unit with the fan at the same time, which means that warm air can be generated. The combination of several or all elements of the above group is also possible.
In one embodiment, the control unit and the vibration detector are designed in such a way that they can detect the presence of a user in a predetermined area of the environment and, as a result, can change the settings of a specific sanitary element. For example, the settings of a first sanitary element are changed when it is recognized that a user is in a first area and the settings of a second or third sanitary element are changed when a user is registered in a second or third area.
The mentioned embodiments of the fitting can be used in any combination, provided that they do not contradict each other.
A fitting arrangement according to the invention comprises a sanitary installation and a previously described fitting, the vibration detector being arranged at a distance from the sanitary installation. With this design, the vibration detector is independent of the sanitary installation, which allows the use of different sanitary installations with the fitting.
In one embodiment, the sanitary installation can be selected, for example, from the group comprising wash basin, shower, bathtub, soap dispenser, lotion dispenser, disinfectant dispenser, hand dryer, hairdryer, toilet and urinal.
In one embodiment, the fitting arrangement further comprises a sound generator, which is arranged at a distance from the fitting. For example, the sound generator is a cracked frog or another device which is able to emit a predetermined characteristic acoustic signal. Two, three or more sound generators can also be provided, which can emit different acoustic signals.
A method according to the invention for changing a setting of a sanitary element of a fitting described above comprises the steps:
In one embodiment, changing the settings can be selected from the group comprising fully and partially opening and closing a valve, switching-on or -off of a pump or fan, and increasing and decreasing the volume flow of the medium delivered by the valve, the pump or the fan.
