    State of the art
    The invention relates to a disinfection device according to the preamble of claim 1 and a method for disinfecting a liquid according to the preamble of claim 7.
    From DE 102012004835A1 a disinfection device for disinfecting a liquid, with an ultrasonic generating unit for generating ultrasound in the liquid and a method for disinfecting liquids by means of ultrasound is already known. A sonotrode of the ultrasonic generation unit is arranged in an ultrasonic reactor which comprises a separate liquid circuit and to which a liquid to be sterilized, for example water from a household pipe system, is fed.
    The object of the invention is in particular to provide a generic device with improved properties with regard to flexibility. The object is achieved according to the invention by the features of patent claims 1 and 7, while advantageous configurations and developments of the invention can be found in the subclaims.
    Advantages of the invention
    The invention is based on a disinfection device for disinfecting a liquid, with an ultrasound generating unit for generating ultrasound in the liquid.
    It is proposed that the disinfection device has an adapter unit which is provided for direct connection of a sonotrode of the ultrasound generating unit to a household pipe system, in particular a common household pipe system, for receiving the liquid.
    Such a configuration can advantageously provide a disinfection device with a particularly high degree of flexibility. A disinfection of liquids, in particular of drinking water, in household pipe systems can be made possible by means of the proposed configuration of the disinfection device with a reduced number of components in a simplified procedural arrangement. By directly connecting the sonotrode to the household pipe system, the sterilization can advantageously take place directly within the pipes of a household pipe system. This advantageously enables a particularly targeted and efficient disinfection of a liquid directly within the pipelines of the household pipe system, which in addition to reliable disinfection of the liquid can also advantageously reduce the accumulation of germs in the form of biofilms on surfaces within the pipelines of the household pipe system. Targeted direct disinfection of individual pipelines can in many cases, especially in cases of pipelines in domestic pipe systems, which are only rarely used or not used at all for long periods of time, advantageously represent a cost-effective alternative to a complete replacement of individual pipes or the entire domestic pipe system. By directly connecting the sonotrode to the household pipe system by means of the adapter unit, a particularly high degree of flexibility can advantageously be achieved, since targeted disinfection of individual pipes is made possible via various connection points within the household pipe system. Furthermore, by directly connecting the sonotrode to the household pipe system using the adapter unit, a number of components can be reduced, for example by eliminating additional pipelines, reaction chambers or the like, which advantageously results in cost savings and a particularly compact design of the disinfection device can, whereby the disinfection device can also advantageously be used in particularly confined spaces. Furthermore, in contrast to common methods for disinfecting liquids, a disinfection of liquids can advantageously take place without the use of further chemical or physical agents, such as, for example, the use of chlorine, ozone or UV light.
    A disinfection device should be understood to mean a device which is provided to reduce, preferably to minimize, a number of germs, in particular bacteria, in particular gram-negative bacteria such as Legionella, in a liquid.
    [0008] An “ultrasound generating unit” should be understood to mean a unit which is provided to provide sound frequencies above the audible range of the human ear using electrical energy. The frequency range of the ultrasound provided by the ultrasound generating unit should be between 16 kHz and 1 MHz, in particular between 16 kHz and 100 kHz, preferably between 16 kHz and 50 kHz and particularly preferably between 20 kHz and 35 kHz. The ultrasound generation unit comprises, without being restricted thereto, at least the sonotrode and at least one ultrasound generator for generating ultrasound. In addition to the sonotrode and the ultrasonic generator, the ultrasonic generating unit can have further units and / or elements, such as a converter, a booster or the like, for example. A “sonotrode” is to be understood as an element of the ultrasound generating unit which is excited by ultrasound to a resonance oscillation and which at least partially transfers this to molecules of a liquid to be sterilized which are directly adjacent to a surface of the sonotrode. It is conceivable that the ultrasound generating unit has at least one further sonotrode, which is provided, for example, for simultaneous use on a further pipeline and / or a further pipeline section of the household pipeline system and / or for use on a pipeline with a different pipe diameter. The sonotrode is intended in particular for use in liquids at a pressure of at least 4 bar, in particular at least 5 bar and preferably at least 6 bar. The disinfection device is preferably provided for cavitation-free disinfection. In this context, “cavitation-free” should be understood in particular to mean that the disinfection of the liquid by means of the disinfection device, at a pressure of the liquid of at least 4 bar, without the occurrence of the physical effect of cavitation and, in particular, exclusively by the effect transmitted to the liquid by means of the sonotrode Ultrasound takes place.
    [0009] “Provided” is to be understood in particular as specifically programmed, designed and / or equipped. The fact that an object is provided for a specific function is to be understood in particular to mean that the object fulfills and / or executes this specific function in at least one application and / or operating state.
    It is also proposed that the sonotrode can be connected to a pipe of the household pipe system by means of the adapter unit at a distance of at most 5 cm. In this way, particularly efficient transmission of the ultrasound from the sonotrode to the liquid to be sterilized can advantageously take place. In addition, a particularly compact and space-saving arrangement of the disinfection device can advantageously be made possible. The sonotrode can be connected to a pipe of the domestic pipe system by means of the adapter unit at a distance of in particular no more than 4 cm, advantageously no more than 3 cm, particularly advantageously no more than 2 cm, preferably no more than 1 cm and particularly preferably no more than 0.5 cm. A surface of the sonotrode that vibrates in an operating state can be arranged at least partially within the pipeline. In this context, “at least partially” should be understood to mean that at least 50%, in particular at least 75%, preferably at least 85% and particularly preferably at least 95% of the vibrating surface of the sonotrode can be arranged within the pipeline.
    It is also proposed that the adapter unit has an adapter element for a direct connection of the sonotrode to a connection point of a standardized pipe of the household pipe system, in particular to a drinking water pipe according to the DIN 1988-3 standard. In this way, the sonotrode can advantageously be connected to a household pipe system with particularly simple technical means. The adapter element of the adapter unit could, for example, be designed as a reducer which is provided for a connection to the pipeline. The sonotrode could be fastened to the connection point of the pipeline by means of the adapter unit, for example by means of a union nut directly to a thread of the connection point or to a thread of the reducer. Alternatively or additionally, it would be conceivable that the adapter unit has an adapter element, which by means of a further form-fitting and / or force-fitting connection, for example a flange connection and / or a clamp connection and / or a press connection and / or a sliding sleeve connection and / or a socket connection or a other connection that appears useful to a person skilled in the art can be connected. The adapter unit can have several adapter elements and / or further additional elements, for example sealing elements or the like. The adapter element can be provided, in particular, for connecting pipes that are customary in house installations, in particular with nominal widths between 5 mm and 50 mm in accordance with the DIN 1988-3 standard.
    It is further proposed that a surface of the sonotrode vibrating in an operating state corresponds at least substantially to a pipe cross-sectional area of a pipe of the domestic pipe system. Such a configuration can advantageously achieve a particularly uniform transmission of ultrasound to the liquid to be disinfected over the entire cross-sectional area of the pipe and thus a particularly high degree of effectiveness in disinfection. The phrase that “the surface of the sonotrode at least substantially corresponds to the pipe cross-sectional area of the pipeline” should be understood to mean that the area of the surface of the sonotrode and the pipe cross-sectional area of the pipeline in particular by less than 25%, preferably by less than 10% and particularly preferred differ by less than 5%.
    It is further proposed that the sonotrode has a material with a modulus of elasticity less than 200 GPa, preferably is formed from such a material. A sonotrode, which has a particularly low modulus of elasticity, can advantageously improve energy efficiency and / or increase the range of a sound pressure acting during disinfection within the pipeline. The sonotrode is preferably made from a titanium alloy, in particular from a titanium alloy with the designation TiAl6V4, and has a modulus of elasticity less than 150 GPa. With such a configuration, compared to a conventional sonotrode made of steel, an amplitude of a sound pressure introduced into the liquid to be sterilized by means of the sonotrode can advantageously be almost doubled with the same generator power of the ultrasonic generator of the ultrasonic generating unit.
    It is also proposed that the disinfection device has a control unit which is provided to control the ultrasound generating unit in a time-recurring manner, in particular periodically. In this way, repeated disinfection of liquids in household pipe systems can advantageously be simplified and a particularly high level of hygiene can be achieved. It is conceivable, for example, that the ultrasound generation unit is connected to the household pipe system over a longer period of time or permanently and the control unit controls the ultrasound generation unit in a recurring manner, in particular periodically, for example once in a week or once in a month, in order to carry out a disinfection process in a sub-area to initiate a pipeline of the household pipe system. Alternatively or additionally, it would also be conceivable that the disinfection device has a sensor unit which is provided to measure a germ infestation within certain subregions of at least one pipeline of the household pipe system directly or indirectly and which is connected to the control unit so that the control unit in the event of an excess a measured value measured by the sensor unit in relation to a threshold value preset in the control unit automatically activates the ultrasound generating unit in order to initiate a disinfection process.
    The invention is also based on a method for sterilizing liquids. It is proposed that a sonotrode of an ultrasound generating unit is connected directly to at least one connection point of a pipeline of a household pipeline system by means of an adapter unit and that at least one liquid located in a partial area of the pipeline is subjected to ultrasound for the disinfection. Such a method can advantageously disinfect pipelines of the household pipe system with simple technical means and in particular without the addition of chemical reducing agents.
    It is also proposed that the sonotrode of the ultrasonic generating unit is connected directly to a connection point of a pipeline of the domestic pipe system, via which the domestic pipe system is connected to a hot water boiler. In this way, an infestation of germs in the supply and / or discharge lines of the hot water boiler, as well as within the hot water boiler itself, can advantageously be reduced and preferably minimized. For regular disinfection, the sonotrode of the ultrasonic generation unit could be permanently connected to and operated on a pipe of the household pipe system via which the household pipe system is connected to a hot water boiler. In this case it would be conceivable that a temperature to which drinking water is heated by means of the hot water boiler and which is usually at least 65 ° C. due to a germicidal effect can be lowered, which could advantageously result in a large energy saving potential.
    It is also proposed that the sonotrode of the ultrasonic generating unit is connected directly to a connection point of a pipeline of the domestic pipe system, which is designed as a riser pipe for vertical transport of the liquid within the domestic pipe system. In this way, sterilization of several floors of the household pipe system can advantageously be achieved simultaneously and particularly efficiently.
    It is also proposed that the sonotrode of the ultrasonic generating unit is connected directly to a connection point of a pipeline of the household pipe system, which is provided for horizontal transport of the liquid within a floor of the household pipe system. A germ infestation within pipelines of individual floors can thereby advantageously be combated in a targeted manner. In particular in larger residential complexes, with a large number of separate residential units on several floors, a germ infestation of individual pipelines within one floor can thus advantageously be combated in a particularly targeted and efficient manner.
    [0019] It is also proposed that disinfection be initiated automatically in a recurring manner and, in particular, at regular periodic intervals. A periodically recurring disinfection can achieve a particularly high level of hygiene within household pipe systems and thus increase safety for a user. In particular in the case of an automatically initiated disinfection, in particular by means of the control unit of the disinfection device, a high degree of comfort for a user can also be achieved.
    The invention is also based on a method for using a disinfection device for disinfecting a liquid. It is proposed that the disinfection device is temporarily connected and operated directly to at least one pipeline of the household pipe system for disinfection of at least a partial area of a household pipe system. In this way, a particularly efficient and cost-effective method for disinfecting liquids within household pipe systems can advantageously be made available.
    In a further embodiment of a method for using a disinfection device for disinfecting a liquid, it is proposed that the disinfection device is connected directly to at least one pipeline of the household pipe system and operated permanently for disinfection of at least a portion of a household pipe system. In this way, a particularly efficient and reliable method for permanent disinfection of liquids within household pipe systems can advantageously be provided.
    The disinfection device according to the invention and the method according to the invention for disinfecting liquids should not be limited to the applications and embodiments described above. In particular, the sterilization device according to the invention can have a number of individual elements, components and units as well as method steps that differs from a number of individual elements, components and units as well as method steps mentioned herein in order to fulfill a mode of operation described herein.
