Definitions

  • the present invention concerns a vaporization apparatus, known more simply by the term "vaporizer”, which can be used to establish a desired level of humidity in a determinate environment, so as to create a comfortable micro-climate and give the user a sensation of general well-being.
  • vaporizer a vaporization apparatus, known more simply by the term "vaporizer”, which can be used to establish a desired level of humidity in a determinate environment, so as to create a comfortable micro-climate and give the user a sensation of general well-being.
  • Vaporization apparatuses substantially consisting of a container in which a determinate quantity of water is poured, and of a closing lid.
  • the apparatus is also provided with electrodes, generally two, which can for example be housed in the lid.
  • the complete closure of the lid on the container entails the at least partial immersion of the electrodes into the water, so as to progressively take it to the temperature of evaporation and hence generate a determinate quantity of steam that is introduced into the environment.
  • level indicator means such as for example transparent windows and/or floating elements, associated with the container, which indicate, outside the container, the actual level of water present in the container and the maximum and minimum nominal filling levels allowed for the correct functioning of the apparatus.
  • the switch that allows to switch on the latter is positioned hidden on the lid, while an end-of-travel block is provided on the container.
  • the block is in a position such as to allow to activate the switch only when the lid is in a condition of total closure with respect to the container.
  • the end-of-travel block in any case keeps the switch activated and consequently the electrodes too.
  • This activation of the electrodes can entail the risk of short circuits of the electric components that are in contact with the water that has overflowed, whether they are inside or outside the apparatus, such as for example displays, push-button panels, feed cables or other, thus compromising the correct functioning of the apparatus, and entailing the risk of damage to the electric feed plant or the danger of shocks to the user.
  • a purpose of the present invention is therefore to achieve a vaporization apparatus for an environment in which the activation of the electrodes is prevented in the case where the actual level of filling of the container exceeds the maximum nominal level provided, thus limiting to a minimum the risk of shocks, short circuits and electric damage in general.
  • the Applicant has devised, tested and embodied the present invention to overcome the shortcomings of the state of the art and to obtain these and other purposes and advantages.
  • a vaporization apparatus comprises at least a container that is filled with water to be transformed into steam, and a lid that can be selectively associated with the container in at least a closed position.
  • the apparatus also comprises electric heating means such as for example one or more electrodes, associated with switch-on means, for example a switch, able to be activated only when the closing lid is in the closed position.
  • electric heating means such as for example one or more electrodes, associated with switch-on means, for example a switch, able to be activated only when the closing lid is in the closed position.
  • the apparatus comprises means to measure the level of filling of the container, which mechanically prevents the positioning of the lid in the closed position, and hence the activation of the switch-on means, when the level detected exceeds a pre-determined maximum level.
  • the activation of the electric heating means for example the electrodes, is inhibited for safety, thus preventing the occurrence of short circuits, shocks or other possible structural damage and/or danger for the user.
  • the measuring means comprises a floating element inserted inside the container and hence able to rise or fall according to the progressive variation in level of the water inside it.
  • the float is provided at the upper part with a stop rod which, when the actual level of the water exceeds the allowed maximum level, emerges from a surface of the container, creating a physical obstacle for the lid during its movement towards the closed position.
  • the container has at least a lateral top-up hole, through which it is possible to top up the water in the container without having to de-associate the lid of the container.
  • a vaporization apparatus hereafter more simply vaporizer 10, according to the present invention is used to spread a determinate quantity of steam in an environment, in order to establish a certain level of humidity in the air and supply the user with a sensation of well-being.
  • the vaporizer 10 comprises a container 11 open at the upper part through a central hole 20 and containing a determinate quantity of water, and a lid 12 that allows to close the container 11, so as to define a compartment 13 inside the container 11 in which the water contained is transformed into steam.
  • the container 11 comprises a containing shell 17 which retains the water both at the bottom and also laterally, and a covering ring 19 associated with an upper edge of the containing shell 17 and having a circular surface 18 which defines the central hole 20 in which the lid 12 is housed in order to close the container 11.
  • a level indicator 21 is disposed, substantially vertical, commonly consisting of a strip of transparent material, on which a graduated scale is reported, so as to allow the user to instantaneously see the level, and hence the quantity, of water contained in the container 11.
  • the level indicator 21 shows a minimum filling value "MIN" of the container 11 to guarantee a correct functioning of the vaporizer 10, and a maximum filling value "MAX” to prevent accidental overflow of the water from the latter.
  • the covering ring 19 also comprises an activation block 23 protruding vertically from the circular surface 18, and a float 25 provided with a stop rod 26.
  • the stop rod 26 is disposed passing through the circular surface 18 and is able to protrude externally, as will be explained in more detail later, with respect to the latter, according to the level of water contained in the container 11.
  • the lid 12 is substantially disk-shaped and comprises a handle 30 which protrudes radially from the disk shape. Once the lid 12 is housed in the central hole 20, the handle 30 allows to rotate the lid 12 with respect to the container 11, until said closed position is reached.
  • the terminal part of the handle 30 obstructs access to the top-up hole 22.
  • the lid 12 also comprises a heating member 15 of the electric type, shown only schematically in fig. 1, consisting for example of two electrodes, not shown, and able to be at least partly immersed in the water contained in the container 11 in order to heat it and generate a quantity of steam; the steam will then be introduced into the outer environment through one or more mouths 27 provided on the lid 12.
  • a heating member 15 of the electric type shown only schematically in fig. 1, consisting for example of two electrodes, not shown, and able to be at least partly immersed in the water contained in the container 11 in order to heat it and generate a quantity of steam; the steam will then be introduced into the outer environment through one or more mouths 27 provided on the lid 12.
  • the heating member 15 can be selectively activated by means of a switch 29 disposed inside the lid 12 in a position not manually accessible to the user.
  • the switch 29 must be able to be activated only when the lid 12 is in the closed position with respect to the container 11.
  • the activation block 23 switches on the switch 29 and thus activates the heating member 15.
  • the vaporizer 10 as described heretofore functions as follows.
  • the water contained inside the container 11 is excessive and exceeds the maximum filling level (MAX).
  • MAX maximum filling level
  • the float 25 is thrust upwards to a height such that its stop rod 26 emerges from the circular surface 18.
  • This mechanical impediment prevents the interception of the switch 29 by the activation block 23 and consequently prevents the activation of the heating member 15.
  • the level of water contained inside the container 11 is comprised below the maximum filling level (MAX).
  • the float 25 remains at a height such that its stop rod 26 remains contained below the circular surface 18.
  • a rod 32 is used, shown in fig. 1 with a line of dashes, provided with a colored indicator that indicates that the maximum filling level has been reached.
  • a sensor may be provided, either electric/electronic, optical, proximity or other, able to send a signal that the maximum limit has been reached and consequently to command the stop rod 26 to emerge, in order to block the rotation of the lid 12 and prevent the heating member 15 from being switched on.
