FIELD OF INVENTION
The present invention relates to air cooler. The present invention more
particularly relates to air cooler with washable sliding filter.
.BACKGROUND AND PRIOR
Witlloul suly pluvisiun lo prolecl air cooler from dust and insects, dust could
easily enter the cooler ,-- -- through coolh~gp ads and panels thus-resulting in-choking- _
of the flute of honeycomb. Insects entering the cooler through cooling pads form
clusters near the cooling pads and inside the flute of honeycomb thus creating an
unhygienic environment. This also reduces the flute size of honeycomb from its
standard size thus resulting in reduced air delivery. Cleaning of cooling pads and
panels clogged with dust over time is a difficult task. It is not possible to clean it
on a regular basis. Further, accumulation of dust on the mechanical parts such as
fan motor, swing motor and pump reduces the efficiency and life of these parts.
Due to dust accumulation, these parts require to be serviced again and again
! leading to high maintenance cost. Thus, this has a major impact on the life and
performance of cooler. Further, mosquitoes come in contact with the tank water
causing pollution of the same. This polluted water becomes a breeding ground for '
. .
. mosquitoes' thus resulting in life threatening diseases like Dengue and Malaria.
Efforts have been made to protect the air cooler from dust etc. Now, in this regard
reference may be made to the following-

DETAIL DESCRIPTION OF THE INVENTION WITH REFERENCE TO
'The present invention makes a disclosure regarding air cooler with washable
L
sliding filter. Reference may be made to fig. 1 and 2 illustrating a desert cooler.
t Here, a dust filter (1) is provided with side-panel (2) on each side and also with . .
back panel (3) of the desert cooler.
! The dust filter is placed between a honeycomb pad (5) and respective panel (2, 3),
wherein the filter is detach.at ble. . Q
It is preferably made of a Nylon mesh which'captures dust, insects and other
pollutants and prevents them from entering the cooler through the panels and
pads. Sliders (not shown) are provided on the side panel and back panel for
sliding the dust filter therethrough. It can be pulled upwards by sliding it by

means of dust filter handle (4) placed on the top of the filter. This facilitates
cleaning process.
.Now, reference may be made to fig. 3 . a d 4 in respect of window cooler.
Here also there is a provision of a :dust filter (8) on the side panel (9) and back
panel (10). It is located between the honeycomb pad (11) and respective panel
(991 0).
In the window coole; also, the dust filter is preferably made of a Nylon mesh
.! which captures dust and other pollutants and prevents them from entering the
cooler. Sliders are provided on the side panel and back panel for sliding the dust
filter therethrough. It can be pulled upwards by sliding it by means of dust filter
handle (12).
.I.
The material of dust filter is not restricted to nylon. Thus, other materials readily
apparent to a person skilled in the art are understood to be within ambit of the
present invention. ,
In Personal Cooler, dust filter is provided on the back panel only. Since there is
no open space in the side panels dust filter cannot be provided in the side panels.
