[0001] The present invention relates to an ironing board with aspirator.
[0002] In particular, it relates to ironing boards which are equipped with a work surface
which is perforated or in any case steam-permeable and below which means for aspirating
the steam emitted by the iron and for removing the moisture (steam and condensate)
present below the work surface itself are provided.
[0003] Ironing boards of this type, in which the aspirator is directly operated by a pedal
at the discretion of the operator, are already known. In other known ironing boards,
the aspirator is connected to the steam iron and is controlled and operated depending
on the amount of steam emitted by the iron itself. The steam delivery of the iron
is regulated directly by the operator, in general by means of a push button. Basically,
the greater the amount of steam emitted by the iron, the greater therefore will be
the amount of fluid removed by the aspirator.
[0004] However, the degree of moisture present below the work surface not only depends on
the amount of steam emitted by the iron, but also on various other parameters, such
as, for example, the type of garments to be ironed, the humidity and temperature of
the working environment, etc.
[0005] In the present-day ironing boards equipped with an aspirator, since regulation of
the latter is effected solely on the basis of the steam delivery of the iron without
taking into account the other significant parameters, it may indeed happen that in
certain working situations aspiration is too strong and in other situations too weak.
In other words, it is impossible to achieve an optimum control of the degree of moisture
present below the work surface of the ironing board.
[0006] The object of the present invention is to overcome the abovementioned drawback of
the prior art by providing an ironing board equipped with an aspirator which is capable
of keeping under control in any case and in any operating condition the amount of
moisture present below the work surface.
[0007] One advantage of the invention is to ensure that the degree of moisture present in
a moisture-collecting chamber arranged below the work surface of the ironing board
does not exceed a predetermined and resettable maximum limit.
[0008] Another advantage of the invention in question is that it is simple and economical
in design and is also easily applicable to ironing boards which are commercially available
at the present time.
[0009] These and still further objects and advantages are all achieved by the invention
in question, as characterized by the claims indicated below.
[0010] Further characteristic features and advantages of the present invention will become
more apparent from the following detailed description of an embodiment of the invention
in question, which is illustrated by way of a non-limiting example in the accompanying
figures in which:
- Figure 1 shows a schematic perspective view of an ironing board provided in accordance
with the invention and
- Figure 2 shows a schematic longitudinal section along a vertical plane of the ironing
board according to Figure 1.
[0011] Referring to the abovementioned figures, 1 shows in its entirety an ironing board
comprising a board 2 equipped with a steam-permeable work surface 11 with a plurality
of uniformly distributed through-holes 3.
[0012] An aspirating device 4 of the known type is mounted on the ironing board 1 in a suitable
housing located close to the work surface 11. The aspirating device 4 communicates
with an aspiration chamber 5 which is arranged below the work surface 11 and is delimited,
at the top, by the work surface itself and, at the bottom and on the sides, by steam-impermeable
walls 6 onto which part of the steam present in the aspiration chamber 5 can be condensed.
[0013] The aspirating device 4, which can be connected to the electricity mains by means
of a power supply cable 10, can operate, following actuation, so as to lower the pressure
in the aspiration chamber 5 and thus create a pressure gradient between the upper
surface and the lower surface of the work surface 11. In this way the steam emitted,
during use, by an iron 7 is able to pass more easily through the garment being ironed
and then enter the aspiration chamber 5, passing through the holes 3. The aspirating
device 4 moreover removes the steam and condensate which collects in the chamber 5.
In the accompanying Figure 2, the path of the steam is schematically shown by arrows
8.
[0014] The ironing board 1 is equipped with a plurality of moisture detectors 9 of the known
type which are arranged inside the aspiration chamber 5, being located close to the
bottom side of work surface 11 and uniformly distributed throughout the chamber 5.
The various moisture detectors 9 are connected to the aspirating device 4 such that
the signals supplied by them, which correspond to the moisture value detected, may
be used for actuation of the aspirating device itself. The connection between the
moisture detectors 9 and the aspirating device 4 may be effected, for example, by
means of a suitably programmed electronic circuit of the known type not shown in the
figures. Basically, such a connection may be made so that when one or several detectors
9 indicate that the degree of moisture in the aspiration chamber 5 exceeds a certain
predetermined and resettable value, the aspirating device 4 is operated so as to remove
the excess moisture until a moisture level which is lower than the pre-selected maximum
limit is restored in the aspiration chamber 5.
[0015] During use, the moisture in the aspirating chamber 5 is always maintained at a value
below the pre-selected maximum limit, irrespective of the working conditions and,
in particular, whatever the type of garment to be ironed, its degree of moisture,
the humidity and temperature in the environment in which operation takes place, the
steam delivery of the iron, etc.
