Definitions
- the invention relates to a device for sterilizing water which flows through a sanitary device
- a circuit arrangement for operating the flash lamp which has a pulse generator which generates a sequence of output pulses for controlling the flash lamp.
- the object of the present invention is to design a device of the type mentioned at the outset in such a way that the service life of the flash lamp is as long as possible and the energy consumption of the entire device is as small as possible.
- a flow rate sensor is arranged in the waterway and generates an output signal which is representative of the amount of water flowing in the waterway per unit of time;
- a microprocessor is provided in the circuit arrangement, to which the output signal of the flow rate sensor is fed and which is connected to the pulse generator, wherein
- the pulse generator is controlled by the microprocessor in such a way that the repetition frequency of its output signal increases with the amount of water flowing in the waterway per unit of time.
- the invention is based on the knowledge that the service life of the flash lamp essentially depends on the number of flashes emitted by it. If this number of flashes can be kept to the minimum necessary to achieve the disinfection effect, the service life can be extended. For this reason, according to the invention, the flow rate sensor is located in the waterway intended. This gives the microprocessor that controls the pulse generator information about the amount of water to be sterilized per unit of time. If this is low, it is sufficient that the microprocessor controls the pulse generator in such a way that the pulses which ignite the flash lamp have a relatively low repetition frequency. For the relatively small amount of water, relatively few flashes of the flash lamp are then sufficient to bring about sufficient disinfection.
- the microprocessor causes the pulse generator to generate its output signals with a higher repetition frequency.
- the flash lamp fires frequently, which takes into account the larger amount of water flowing through per unit of time.
- the number of pulses is dynamically adapted to the amount of water flowing per unit of time; there is no "overdosing" of flashes, as occurred in the prior art and which is no longer necessary to sterilize the water.
- the flash lamp can be completely deactivated if no water flows in the water path. With this, the flash lamp is undoubtedly the most protected and the energy consumption reduced to zero.
- the pulse generator generates output pulses with a low repetition frequency if no water flows in the waterway. This means that even during the "rest periods" of the sanitary facility, there is a certain disinfection effect with which the resettlement takes place is prevented by germs or germs that have settled in this or in filters of the sterilization reactor during the operating phase of the sanitary facility can be reliably killed.
- the reference numeral 1 - in thick lines - represents the water path through which the water to be sterilized flows from the connection 2 to the house line to the outlet opening 3 of the water outlet 4.
- the water path 1 there is a solenoid valve 5, a flow rate sensor 6 and a sterilization reactor 7, which contains a xenon-quartz flash lamp 14 in a manner known per se and which is itself accommodated within the water outlet 4. That of the light of the xenon
- Quartz flash lamp 14 sterilized water flows from the sterilization reactor 7 to the outlet opening 3.
- This circuit arrangement comprises a voltage supply device 8 operated by the mains voltage, which supplies the required operating voltages for a solenoid valve driver 9, detection electronics 10, a microprocessor 11 and a pulse generator
- the microprocessor 11 is connected to the solenoid valve driver 9, the detection electronics 10, the pulse generator 12 and the flow rate sensor 6 and controls the operation of the disinfection device in the manner described in more detail below.
- the pulse generator 12 generates pulses which are necessary for the operation of the xenon quartz flash lamp 14 contained in the sterilization reactor 7, with a repetition frequency which is controlled by the microprocessor 11 in a manner which will also become clear below.
- the output of the solenoid valve driver 8 is connected to the solenoid valve 5.
- a certain logic e.g. with a certain delay
- the load on this xenon-quartz flash lamp 14 is adapted to the actual need: the more water flows, the more often the xenon flashes. Quartz flash lamp 14. Overall, the lifespan of the xenon quartz flash lamp 14 is increased and the energy consumption of the entire device is reduced. This without having to accept the disinfection effectiveness of the disinfection reactor 7.
- the microprocessor 11 is used - if necessary with a certain logic, e.g. time delay - the solenoid valve driver 9 is applied so that the solenoid valve 5 is closed.
- a certain logic e.g. time delay - the solenoid valve driver 9 is applied so that the solenoid valve 5 is closed.
- the microprocessor 11 drives the pulse generator 12 back to an "idle state".
- this "idle state” can look like that
- Xenon quartz flash lamp 14 is no longer activated, so the function of this lamp 14 is completely stopped.
- Base load means a relatively low repetition frequency, with which care is taken to ensure that no germs can develop or settle in the area of the water outlet 4 even when the water is not flowing.
- the sterilization reactor contains 7 filters in which microorganisms may have separated during operation, that is to say when the water is flowing. In the "resting phase" of the xenon quartz flash lamp 14, these microorganisms retained in the filter can be reliably killed, for example overnight. This can be done with a relatively low radiation power, since a relatively large amount of time is available.

Abstract
Dans un dispositif servant à désinfecter de l'eau qui traverse un appareil sanitaire, il est prévu un réacteur de désinfection (7) dans lequel se trouve une lampe éclair produisant une lumière U.V., notamment une lampe éclair au xénon-quartz (14). L'eau qui traverse d'appareil sanitaire est sollicitée par les éclairs de cette lampe éclair (14) et les germes qu'elle contient y sont détruits. Afin de prolonger la durée de vie de la lampe éclair (14) et de diminuer la consommation d'énergie du dispositif, il est prévu un capteur de débit (6) dans le parcours de l'eau (1). Les signaux de sortie que le capteur émet et qui sont représentatifs du volume d'eau s'écoulant par unité de temps, sont acheminés jusqu'à un microprocesseur (11). Ce dernier pilote d'une part un générateur d'impulsions (12) dont les signaux de sortie alimentent la lampe éclair (14), de manière que la cadence de récurrence de ces signaux augmente, à mesure que le volume d'eau mesuré par unité de temps augmente.
