Description

Air Cleaner
The present application relates to an air cleaner and in particular to
an air cleaner with a disposable housing and filter.
An increasing problem has grown, with the advent of modern living,
in the increase in airborne pollutants, and the increase in positive ions that
surround us. These pollutants are predominantly in the form of airborne
solids, such as pollens and metal ion dusts, with a positive ion charge.
Asthmatics and chronic hayfever sufferers react adversely to such
pollutants. This problem has been increased with the increase in pollution
in many cities around the world, due in a large extent to the increase in
urban traffic, and as people travel more for work and pleasure, people are
now more exposed to these problems.
Whilst existing commercial air conditioner units cool the air, they do
not, usually, remove the small airborne solids, such as pollens nor do they
restore the correct electrostatic charges to the air. Existing personal air
cleaner units are available, but these are cumbersome to be carried by
international travellers and are, usually too expensive and inefficient. The present invention seeks to ameliorate these problems by
providing an air cleaner comprising:
a base;
a motor located on said base ;
an impeller connected to and driven by said motor;
a foldable housing which has a folded position wherein the housing
is in a substantially collapsed condition and an erected position wherein
the housing defines a filter chamber, having an open base;
at least one air inlet located into said housing;
a filter material covering said at least one air inlet
wherein in use with the foldable housing in its erected position, the
foldable housing is positioned with its open end engaging with said base,
whereby the impeller draws air through the filter material into the filter
chamber, and expels the thus treated air.
In another form the invention comprises an air cleaner comprising:
a base having a first chamber;
a motor located in said first chamber ;
an impeller connected to said motor and adapted to rotate within
said first chamber; a foldable housing which has a folded position wherein the housing
is in a substantially collapsed condition and an erected position wherein
the housing defines a filter chamber, having an open base;
at least one air inlet located in said housing;
a filter material covering said at least one air inlet
wherein in use with the foldable housing in its erected position, the
foldable housing is positioned with its open end into the first chamber of
the base, whereby the impeller draws air through the filter material into
the filter chamber, and expels the thus treated air from the first chamber of
the base.
Preferably, negative ion discharge units are positioned to discharge
negative ions into the air being expelled from the air cleaner.
The present invention will now be described with reference to the
accompanying drawings in which:
Figure 1 illustrates a perspective view of an air cleaner according to
one embodiment of the present invention;
Figure 2 illustrates cut away side view of the air cleaner illustrated
in figure 1 ; Figure 3 illustrates an exploded view of the base of the air cleaner
shown in figure 1 ;
Figure 4 illustrates a circuit board lay out of an air cleaner
according to one embodiment of the present invention; and
Figure 5 illustrates a circuit diagram of suitable for an air cleaner
according to one embodiment of the present invention; and
Figure 6 illustrates a view of the blank to form the housing.
The present invention comprises an air cleaner (1) having a base
(2). A printed circuit board (3) such as that shown in figure 4 is located
with its components facing downwards, in the base chamber (4). Batteries
(not shown) can be located below the printed circuit board (3) to power the
board (3).
A suitable motor (5) is located on the board (3) and drives an
impeller (6). As shown in figure 2, a volute type shroud (7) is positioned
within the chamber (4) around the impeller (6) to assist in the flow of air
through the air cleaner (1 ), as the vanes (9) draw the air from the filter
chamber (10) and out of the outlet (8). The filter chamber (10) is formed from a foldable or collapsible
housing (11 ). The shape of chamber and the method of attaching it to the
base can take any desirable forms, such as cylindrical, spherical, triangle
prismal, or pyramidal . In the present embodiment the foldable housing
(11 ) is formed from a cardboard in a blank as shown in figure 6, and can
be packaged in the flattened form, with the base (2) and motor (5). The
filter material (16) is affixed to the area around the inlets (15) and could be
covered by a removable mask of cardboard which has perforated edges
for removal.
The blank is folded to form the housing (11 ) which is rectangular in
shape, it could be sold in a blank form with suitable glue tabs for
assembling, or with slits and tabs . In another form (not shown) a separate
cap is fitted to seal the top of the filter housing (11 ) and could be made
from any suitable material such as plastics or cardboard.
As shown in figures 1 , 2, & 6, three of the faces (12, 13 & 14) have
cutouts of any desired shape or dimensions to form inlets, or in the
present case a single inlet (15). A suitable filter material (16), such as an
electret filter which is comprised of a matrix of permanently charged
polypropylene fibres for example, 3M Filtrete ™ G150 covers the inlet (15). An activated carbon filter can form an outer layer over the inlet (15). The face (17) is solid and has an opening (8) at its lower edge (23)
communicating with a second or outlet chamber (18). Thus in use, the
outlet chamber (18), when the foldable housing (11) is positioned in the base chamber (4), is connected to the outlet (8) of the base (2). Any suitable design of outlets or outlet (21 ) are provided on the front face (19).
Any suitable number of negative ion discharging pins (22), see
figures 4 & 5, are provided adjacent the outlet (8) to restore the treated air
to the correct negative ion balance. Thus the air is both filtered and
treated with negative ions to clean and purify the air, as the air is drawn through the filter material (16), and passes through the impeller (9) past the negative ion emitting pins (22) up through the chamber (18) and out of
the outlet (21).
The air cleaners also have a socket (20) for connection to a 12 volt
200 ma adaptor for connection to a mains power supply. The materials
used for the construction of the filter chamber housing can be any suitable
disposable materials such as cardboard or recyclable plastics, and the
filter material could be able to be heat welded to the material of the
housing. Further the housing can be formed directly from self supporting filters, for example in the form of a cylinder, with an outlet in the base of
the air cleaner to expel the treated air.
It should be obvious to people skilled in the art that modifications
and alterations can be made to the above described invention without
departing from the scope or the spirit of the invention
