discuses about how the modern dishwasher are
substantially more efficient than older dishwashers. It also
discusses about variety of factor affecting efficiency and
performance to reduce dishwasher use. [5]
“Design of basic model of semi-automatic dish washer
machine” - In this dishwasher works with help of motor,
universal motor, conveyor belt and microcontroller for
time delay. Microcontroller helped to provide delay to

placed on the conveyor belt go in the first washing
compartment where it is cleaned with soap water and
rubbed with the brushes. then passed to succeeding
chamber where it is washed with the clean water. [6] Fig -1: Model of Dishwasher machine
2.Material and mechanism
On the basis of our study and references we use, weight
and cost of machine found to be factors where
improvement is to be done. This issue can be resolved by
selecting proper material for the fabrication. we have used
high density polyethylene. This material has property like
good chemical resistance and strength.
Cleansing in dishwasher depends on four main factors
mechanical action, time, chemistry and temperature.
Mechanism which generally used in available dishwashers
are time consuming, and not up to the mark in terms of
cleansing. We have tried to improve this limitation by using
agitator-based mechanism.
3.WORKING Fig: some main components of machine
Dishwashing machine is a sort of mechanical machine
broadly utilized for cleaning eating-utensils and dishes in
private homes and inns to completely eliminate the work
of hand washing. Particularly have higher efficiencies than
different kinds of manual dishwashing (which rely to a
great extent upon actual scouring to eliminate dirtying).
The dishwashers are associated with the kitchen sinks for
water supply. The machine contains Inner drum where

is flowed by a siphon to the inner drum. Inner drum holds
the soapy water. Inner drum is water tight to prevent

It takes place inside the inner drum when it time for
washing, rack loaded with dishes placed inside inner drum
and inlet valve supply water to the inner drum. Agitator at
bottom of inner drum spin soapy water around dishes for
the effective cleaning.
4.1 SIMULATION
As the agitator spins, it's subjected to a number of forces
that attempt to stop its motion. Model parts are made and Fig: displacement due to stress

order to simulate the impact of forces on an agitator, a 5.FABRICATION
simulation is performed. The simulation is performed
using a PVC rigid material. Fabrication is done with various manufacturing processes.
To bring design model into realization takes great effort
and bring no of challenges. Design is done on software like
Catia, Solidworks, etc. various dishwasher uses spray arm
mechanism, etc. we have use agitator-based mechanism
while fabrication we have consider all the factors which
will affect the feasibility of machine. Type of mechanism is
a factor which affects the feasibility of design. At the time
of fabrication of agitator water leakage problem, rise. It is
big issue because it not only hampers the life of product,
but also can cause severe accident hence we used
mechanical water seal to restrict water leakage. While
fabrication it became important to select material
properly material should have good machinability,
chemical properties which are suitable according to type
of product, etc. maintaining accuracy and precision is
equally important to archive quality product. Proper

6.APPLICATIONS
It is used in large-scale kitchens such as
hotels, restaurants, etc., where there is
a requirement for more dishes.
It is also used in family kitchens.
7.ADVANTAGES
