Abstract:
The present disclosure concerns a ventilation system to be applied to a micronizer, in such a way that the ventilation does not prevent nebulization, rather it disperses it in an environment that for example is to be sterilized. Thanks to a particular configuration, the ventilation system is also resistant to water present in the environment to be sterilized.

Description:
CROSS REFERENCE TO RELATED APPLICATIONS 
     The present application claims priority to Italian patent application no. RM2014A000688 filed on Nov. 27, 2014. The entire disclosure of the foregoing application is hereby incorporated herein by reference. 
     FIELD 
     The present disclosure relates to a ventilation system for a micronizer, for example for washing machines-sterilizers, decontaminating washing machines, washing systems for isolators, glove boxes, C-rabs. 
     More in detail, the present disclosure concerns a ventilation system to be applied to a micronizer, in such a way that the ventilation does not prevent nebulization, rather it disperses the nebulization in an environment that for example is to be sterilized. Thanks to a particular configuration, the ventilation system is also resistant to water present in the environment to be sterilized. 
     BACKGROUND 
     There are on the market micronizer devices that atomize a liquid solution in an environment. To increase the spread of the spray, common electric fans can be utilized, for example the micronizer can be placed vertical to the plane of rotation of a fan. 
     However, these prior art solutions are not suitable for environments in which there is a certain amount of water that can short-circuit the fan. 
     The replacement of the fan with a jet of compressed air from the bottom upwards which sweeps over the micronizer is not conceivable as well, because the water would tend to deposit on the mouth shooting compressed air. 
     The object of the present disclosure is to provide a ventilation device for micronizer which solves the problems and overcomes the drawbacks of the prior art. 
     It is further object of the present disclosure an atomizing system that makes use of the device object of the disclosure. 
     It is subject-matter of the present disclosure a device and a system such as in the attached claims, incorporated herein by reference.

     DETAILED DESCRIPTION 
     Referring to the accompanying figures, the system  1000  includes a base  200  on which a frame  110  is placed with at least a vertical element  160 ,  160 A (i.e. perpendicular to the base  200  which is typically flat). In the example of the figures, there are three vertical elements  160 , 160 A placed at 120° from each other. One of these elements  160 A is provided with a conduit  165  which leads from the bottom up to a certain height, and in which compressed air can be blown. 
     From one or more of these elements  160 , a horizontal arm extends that leads into a central chamber at least partially occupied by the micronizer  300 , which has a propeller  301  at its upper end (again with respect to the base  200  which is typically secured to the bottom  700  of a washing machine). The element  160 A that comprises the duct  165  possess this arm, since in this case the arm also is holed, so that the air blown in at the base of the element  160 A can reach the central chamber. 
     It is here to be specified that the vertical elements are not essential, because the air (e.g. compressed air) may be injected directly into said central chamber. The vertical elements  160  are preferred because they allow not to occupy space laterally but only under the base  200 , thus maximizing the space available for the sterilization chamber of a washing machine, the base  200  being in this case the base of the washing machine. 
     It is now specified that the central chamber can be formed, according to the illustrated aspect of the disclosure, by a main frame or housing  140  connected to the frame  110  by the arms  130  (the central frame  140  can be formed in one piece with the ends of the arms). This central frame  140  is shaped so as to comprise a circular inner chamber  135  so that the air that arrives from the arm  130 A circulates in this circular inner chamber  135 . Said internal circular chamber  135  is delimited according to an aspect of the disclosure by two O-rings  151 ,  152  (or in general, watertight/fluid-tight means) placed one above the other in the vertical direction. The internal circular chamber possesses holes  136  which constitute channels that go downwards, i.e. towards the base  200 . The air exiting from the holes  136  downwardly meets a bottom  212  surrounded by a relief or ridge  211  (“U”-like shape) so that air (or any other fluid suitable for the purpose) is forced to go upwardly, or at least partially in the direction perpendicular to the base  200 . In this way, the air blown in will allow a ventilation upward that will spread the spray created by micronizer. 
     According to the shown aspect of the disclosure, the holes  136  end before the bottom  212 , running into a further circular chamber  410  and subsequently into a slot  420  which is created between the lower edge  141  of the central frame  140  and a ridge  220  internal to said bottom  212  (accordingly a “U”-type gap). However it is clear that the most general essential feature is that of a conduit which from the internal circular chamber  135  brings air to strike against the bottom  212  and the ridge  211 . 
     The element  500  is a plate that is fixed from below to the base  200  (for example by a bolt  510 ) to secure the micronizer within the central chamber. 
     The element  600  is a ring that allows the fixing of the frame  110  to the base  200 , from below the base  200 . 
     The element  120  is an optional cover frame, to protect the propeller  301  of the micronizer, fixable to the vertical elements  160  through corresponding radial ends  123  for fastening at the ends of cover arms  124  connected to a central cap  121 . Curved arms  122  join the cover arms  124 . 
     The path of the air is indicated by arrows in the drawings. 
     Referring to  FIG. 6 , the Inventor has found that even the distribution of air in the same ventilation system of the disclosure is considerably improved if a chamber  430  is added to the device of the preceding figures, in communication with the chamber  136  and having sufficient size to harmonize the pressure of the ventilation fluid. 
     It must be said that in all the aspects of the disclosure the conduit  420  can have a length (and a section) to be determined according to the type of used fluid, so that it is not quantifiable a priori. The conduit  420  may stop before or run along the valley  212  or end close to the ridge  211  according to the needs. Even the above-mentioned U-shape may be modified so as to optimize, by means of known simulation tools or by calculations and tests, the flow and the final distribution of the fluid. 
     In the foregoing aspects of the disclosure have been described and variants of the present disclosure have been suggested, but it is to be understood that those skilled in the art can make other variations and changes, without so departing from the related scope of protection, as defined by the appended claims.
