Definitions

  • the invention relates to a humidifier and a Transducerermodul for a humidifier.
  • One principle used by many humidifiers for indoor humidification is the misting or atomizing principle.
  • a mist of tiny water droplets such as a nebulizer, for example, a water-covered transducer plate is used, which is excited to ultrasonic vibrations.
  • Vernebier have the disadvantage that in the water existing germs are atomized with. Therefore, a very frequent replacement of the water supply is necessary accompanied by a thorough cleaning of the water tank.
  • US 4,630,475 shows a humidifier with water tank, wherein the water tank has a window through which it can be illuminated.
  • An ultraviolet lamp can be used to irradiate the water in the tank, preventing, according to the authors, bacterial growth both in the tank and in the sputtering chamber.
  • US 5,859,952 shows an air humidifier having a water tank, a water dispersing unit and a conduit therebetween.
  • a UV lamp is arranged so that the water in the line is UV irradiated on the way from the tank to the dispersion unit.
  • the dispersing unit is an evaporator, but may also be an ultrasonic atomizer or a vaporizer.
  • US 2013/0249126 shows a nebulizer humidifier with an annular discharge body. Water from a water tank passes a UV light source located in a tube into a water reservoir. On the side of the water reservoir opposite the tube there are two ultrasonic transducers which atomize the water. The US 2013/0249126 therefore also teaches to sterilize water to be atomized on the way from the tank to the dispersion unit.
  • the sterilization of the water in the water tank or in the line for water absorption of the dispersion has the disadvantage that can also form in this water intake germs that are not covered by the sterilization. This is particularly important if a longer period of rest took place between two uses of the humidifier.
  • KR 2012 0040513 shows a nebulizer humidifier in which a UV source downstream of the dispersing unit and suitably located above the dispersing unit is present.
  • the atomizer humidifier according to KR 2012 0040513 is equipped with two UV LED modules.
  • a first UV LED module is located in the outlet and sterilizes the already nebulized water in the outlet.
  • a second UV-LED module with a light guide rod is located in the water tank.
  • the KR 2005 102317 also shows UV LEDs above the ultrasonic atomizer.
  • WO 2008/002123 shows a nebulizer humidifier for insertion into a ceiling.
  • the humidifier has two housing parts, of which an upper housing part is attached to the ceiling and carries the actual atomizer and a lower housing part is designed as a water vessel, which is attached to the upper housing part and can be removed without tools.
  • the document mentions the possibility of mounting a UV lamp in the vicinity of the water reservoir in order to irradiate both the liquid in the reservoir and the air in its vicinity.
  • the UV lamp is attached to a rod which carries the atomizer, which thus belongs to the upper housing part.
  • the UV light source must be operated constantly during operation and with a comparatively high intensity.
  • the assembly is not trivial and requires electrical feedthroughs for the light source to the wet outlet area above the nebulizer. This brings with it the necessity of a completely new housing construction compared to existing humidifiers.
  • the humidifier has a water reservoir and a nebulizer module with a vibrating element (eg a vibration plate), which can be excited to ultrasonic vibrations.
  • the vibrating element is covered with water during normal operation of the humidifier.
  • the water-filled area above the vibrating module will be hereafter referred to as the "water receiving area.”
  • Suitable means will be to add water from the water reservoir to the water holding area to keep the water element coverage approximately constant, in most embodiments without a pump so that the - approximately constant - water level of the Water intake range is lower or at least not much higher than the bottom of the water tank.
  • the oscillating element has, for example, a vibration exciter (it can consist of this or else have further elements, for example a vibration excitable vibration body made of a different material).
  • the vibration exciter is, for example, designed as a transducer, in particular as a sound transducer, for example a piezo transducer. At the vibration exciter an excitation signal designed according to the desired oscillation is to be applied.
  • At least one light source for generating ultraviolet light is arranged to couple light into the water receiving area from a position below the water level (the water level).
  • the at least one light source is at least partially covered by the water in the water receiving area.
  • the at least one light source is accordingly arranged in particular under the water absorption area or laterally on the water absorption area.
  • the light source itself to be arranged above the water level and to be connected via light guides to the water in the water intake, a light coupling point at which the light from the light guide is coupled into the water in the water absorption area being below the water level, i. in a lower or lateral boundary of the water receiving area.
  • a normal water level (a "level") of the water in the water intake area is a property of the humidifier per se.
  • the water level can be regulated by passive or active control means.
  • Passive control means may, for example, have a float, which closes an inflow on the water reservoir when a certain water level is reached, or they may, for example, work according to the so-called bird-feeding principle.
  • Active control means may operate with a measurement of the water level or with a sensor operating in "on / off" mode.
  • the UV light source is arranged so that it is directly coupled to the water above the vibrating element.
  • This provides advantages in terms of the effectiveness of sanitizing, particularly unlike mounting in the line or in the water tank, since in the latter cases the water behind the line is not sterilized, i. If, for example, germs form during prolonged decommissioning, they are atomised during commissioning.
  • Another advantage is in terms of energy consumption, both compared to an arrangement in the tank, which requires a relatively high radiant power for sterilization of the whole tank, as compared to the arrangement in the outlet, because in the latter case only a small amount of water is irradiated and so due to the short residence time of the water droplets constantly a relatively high radiation power must be present.
  • the arrangement of the radiation source below the water level - ie under water - also a physical effect is profitably usable, namely the effect that in a medium of higher refractive index (water) coupled radiation at oblique incidence on an interface to a medium of lower refractive index ( Air) is at least partially reflected back into the medium.
  • a medium of higher refractive index water
  • Air refractive index
  • the effect of the radiation due to internal reflections in the water is additionally intensified.
  • This effect is particularly high, since the refractive index difference between water and air in the UVC range is greater than in the case of visible light.
  • the light source (s) is / are arranged so as to illuminate / illuminate the part of the water surface from which droplets detach (ie in particular the water surface immediately above the vibrating element) from below; this includes illuminations from obliquely downwards, for example also by light sources, which are arranged laterally in or on a side wall of the water absorption area and have a broad emission characteristic.
  • the UV light may be coupled into the water-receiving area through at least one lateral window element below the water level.
  • the water receiving area is approximately cup-shaped with a circumferential side wall and the water level below the cup rim, and if the light source radiates through a window in this circumferential side wall in the water receiving area.
  • the side wall of the cup-like volume may under the aspects described above - this applies to all embodiments with cup-shaped water receiving areas - below the water level a Wegsclinittlichen angle to the vertical of, for example. At most 30 °, in particular at most 20 ° and, for example, have at most 10 °. In particular, it can stand substantially vertically.
  • the side wall of the cup-like volume may additionally or alternatively be substantially circular cylindrical or - if the side wall is at an angle to the vertical - be conical; also combinations with conical and vertical sections are possible.
  • This further measure has the following advantage: Depending on the mechanism with which water is supplied from the water tank (water reservoir), the problem of fluctuations in the water level can arise with small volumes in the water absorption area. In the case of a small area which is as small as possible, as discussed above, variations in the volume of water cause relatively marked fluctuations in the water level.
  • the passage between the water reservoir area on the one hand and the water intake area on the other must be large enough so that as much water can flow in at any time as is atomized.
  • he should be small enough to effectively decouple the water receiving area as a separate area from the water reservoir area, so that not by diffusion, for example, during a brief interruption of the irradiation significant amounts of non-sterilized water enters the water absorption area.
  • the diameter of the passage will be at least at its narrowest point significantly smaller than a surface of the vibrating element; it may be, for example, a maximum of 2 cm 2 or a maximum of 1 cm 2 or a maximum of 0.5 cm 2 or 0.2 cm 2 or even less.
  • the light source may, for example, be a lamp based on the gas discharge principle - for example, as a mercury vapor lamp. as such, it may in particular be in the form of a tube; but other forms are not excluded.
  • the at least one light source can be a light-emitting diode, in particular a UV light-emitting diode (LED).

  • UV superluminescent diodes for example UV superluminescent diodes, UV laser diodes, arc lamps, etc. are not excluded. Also possible are combinations of the mentioned light sources, for example. Combinations of UV LEDs with UV gas discharge lamps.
  • the emission spectrum of the light source is preferably chosen such that at least a portion of the emitted light is in the UVC range, ie below 280 nm, in particular between 100 nm and 280 nm. Light in this frequency range has the ability to destroy DNA and thus also germs as such. In embodiments, at least half of the radiant power in the UVC range is emitted by the light source.
  • a regulation of the light source (s) can be set up in such a way that it lights up in continuous operation when the oscillating element is switched on. Other modes of operation may also be programmed, for example, operation of the light source only at power up and then at regular intervals for a period of time.
  • the arrangement of the light source (s) and their coupling to the water receiving area is such that the light is emitted approximately from the plane of the vibrating element.

  • the light source (s) is / are the light incoupling point along a side wall of the water receiving area.
  • the emission characteristic may be such that the light is radiated primarily towards the center, whereby a broad emission characteristic can be selected.
  • Combinations are also conceivable, especially when using more of a light source.
  • the fact that the light is radiated in embodiments, approximately from the plane of the vibrating element, may mean that the light source (more precisely, the location in the light source, where the light is predominantly generated) is not or at most arranged a little above the plane, eg at most 1 cm.
  • the light source may also have a greater vertical distance to this plane.
  • the light source (s) (or light input point (s)) is distributed in the circumferential direction.

Upwardly emitted portions of light that are not reflected back into the water enter the outlet and cause irradiation of the water droplets on the way up, substantially along their entire path. This brings an additional contribution to the effectiveness.
  • the light source is in embodiments an integral part of the nebulizer module. This can be used as a whole in the housing of the humidifier.
