3. Used to remove
wrinkles from
fabric
Introduction
Uses both pressure
and heat
Used to kill
bacteria and lice
commonly found
on shirts
Can be used on a
variety of materials
Works by loosening the
bonds between the long-
chain polymer molecules in
the fibres of the material
Helps remove the
smell of bleach in
the clothes

4. Different parts and
their functions and
how they work in an
iron
3 different wires( Live, Earth , Neutral) supplies mains power to the iron to heat up the iron
Wires connected to Nichrome (heating element) heats up the stainless-steel plate on the bottom.
Thermostat allows the temperature of the iron to be regulated. It is used to change the temperature for the specific needs of different shirt materials

5. Different parts and their
functions and how they
work in an iron
-Lid with rubber stopper helps to store the
water inside the tank by providing an air-
tight seal and prevent any accidental spillage
-Water filler helps take in water to be used
for ironing when required
- Nozzle for water to come out from to
moisten the shirt
-Water tank helps to store the water filled
into the iron and store it until it needs to be
used

6. Different parts and their
functions and how they
work in an iron
-2 Different buttons on the top of the clothes iron allows the user to decide how much water they want to manually release on the cloth.
-One button allows the user to exert a mist of water vapor to get rid of smallcreases
-The other button releases small jets ofwater from the nozzle at the front which helps to moisten the clothes
-Done by moisteningthe cloth first and then heating it up to get rid of the crease by loosening the bonds

7. Different parts and their
functions and how they
work in an iron
- Knob allows the user to choose what type of material they
are ironing
- Sets the iron to different temperatures to most effectively
remove the crease from the different cloth types
- Has an off feature to make sure it is not producing heat
when not in use

8. Different parts and their
functions and how they
work in an iron
-Dial allows the user to choose
between the amount of water that
is automatically let out
-Helps to control the water and
release it properly instead of wasting
it unnecessarily.
-Presets allows the user to see what
mode the iron is in

9. Safety Features
Plastic Cover and
Handle:
-Plastic is aninsulator of
electricity, it does not allow
current to flow through the
handle.
-Prevents user from getting
an electric shock when
using the iron.

10. Safety Features
Thermostat:
-Prevents the iron from
overheating and reaching
dangerous temperature levels.
-Thermostat has a bimetallic
strip made of 2 different
metals.
-When the iron heats up, both
metals expand differently.
-When the iron overheats, the
strip bends towards the metal
that expanded less, opening the
circuit and preventing current
flow.

11. Safety Features
3 pin plug:
-Designed tosupply electricity safely to the iron and
prevent electric shock.
-Consist of 3 wires: Live, Neutral and Earth
-Live wire is red which is connected to a fuse.
-Neutral wire is blue, it’s the wire that routes out the
electric current.
-The neutral wire has a voltage of 0.
-Earth wire is green and yellow which is connected to the
earth pin and to the metal casing of the heating element.
-The earth wire helps to divert the flow of electric current
away from the iron'scasingif the live wire touches it.

12. Timeline of Innovation
1882
1700
Henry Seely White inventedelectric
flatiron.It weighedalmost 6.8kg
and took along time to heat.
Flat iron, were used mainly in the
1800s, were thick slabs of iron
heated in a fire or stove to iron
clothes.

13. 1910
There were manyvariations of fuels
source(e.g.,Kerosene, ethanol). Still used
as a backup device since power outages
are frequent.
2023
SensorSteamfunction switches off the
heat andsteam as soon as you release the
iron. When youtouch the iron again, the
powerful motor gives youfull power, steam
and heat right away.
Future
One of the major problem:
Electric irons have a polished smooth ironing surface which has an
increased area of contact and thus results in greater heat transfer
thereby leading to burning of the protruding fibers, ultimately
resulting in shine on the fabric surface.
