ABSTRACT
This paper discusses how they reduce people's efforts to wash dishes and utensils. The utensils washer is designed to make the
utensils washer easier and more efficient. This paper also discusses the problems facing the use of Automatic utensils washer
and solutions to those problems. An automatic washing machine uses a huge amount of energy, water, time and is very
expensive. And since it is very expensive, the use of automatic washers in our country is very limited. By using an automated
container, it can significantly reduce the time and effort of people. And by using plastic parts for partitioning, the overall
weight of the assembly is reduced. By dividing the assembly into 3 parts for washing dishes, cleaning dishes and washing
glasses, much work can be done in less time. In the normal washing process the amount of energy of the people and the
amount of water is used. So keep that in mind, in order to reduce this Semi-Automatic container washer. And we can use this
in places where dishes are often used for example, a wedding event. This utensils washer is more useful for household use,
which saves time and costs rather than wasting on cleaning dishes by hand and consuming large amounts of energy.
Keywords: Analysis, Research, Semi-Automatic, Integration, rotary nozzles.
I. INTRODUCTION
Vacuuming is the world's most popular work, in many families people hand wash the dishes by hand and tissue and
chemically. It may also lead to a clinical, physical disability and back pain that can affect an operator's health. Most housework
is done by women and some can be very difficult and time-consuming. So in many ways we can improve their lifestyle, and
one thing we can improve on is the way they wash their dishes. At present, the task of washing dishes is done by women, and it
can be very hard work as it is done many hours a week. The same can happen to the wedding party and its customers. In
today’s world of automation Era it is impossible to find any field used for atomization that reduces human effort, improves
productivity and also improves efficiency. Then it would be the largest production industry, pharmaceutical industry,
hospitality garden and Household or automated kitchen. But our country is not getting enough benefits from automation and
the reason behind this is limited information about automated products, high cost of the device, and type of nascence sensing
by atomic devices. However this fear is not apparent in a product that does not include many Sensors, Complex Electronic
Circuits, and simple user devices. The most common example of an Automatic dishwasher. This portable shower is widely
used internationally. However it is seldom seen in our country.
Why we select the project –
Purpose:
The main purpose of the dishwasher is to reduce the cost of an automatic dishwasher and to provide good cleaning service. It
required less vitality and less water utilization. The dishwasher time can be adjusted according to the needs of each customer.

effort needs, time management and energy use are discussed. Build type will be updated. Recent research is being done to
improve systems. The basic principle of performance is systematically looked at in this paper and its future scope. Keywords-
Washing machine, motor, gears, parenting, plates, water & cleaner. Keywords- utensils washing machine, motors, bearing,
storage tank, water & detergent.
Challenges to this Project Washing dishes is most ordinarily done action on the planet, in the vast majority of families' kin
wash dishes by hand which is stressing to muscles and cleanser is artificially hurtful As far as manual procedure is worried in
places of India, washing is finished by hand scouring which is stressing to the muscles through its vitality and postural
necessities. It might likewise prompt clinical, anatomical issue and back agony which may influence the administrator's
wellbeing. A considerable lot of their family unit tasks are performed by the ladies and some can be truly testing and tedious.

III. MODELING AND ANALYSIS
Design & Parts Analysis of Basic Structure of Machine
Self-loader dish washer comprise of engine with siphons in which water is move through PVC pipes which is associated with
turning planes which is in upper side and descending side. Siphon is help to pivot the stream. These streams are sprinkling the
water with required weight on the plates and utensils. Controller is given in the machine which controls the activity of
machine. Water utilization of this machine is relies upon client. Time, water and vitality utilization are extremely less. Engine
is utilized to change over electrical vitality to Mechanical vitality. At the point when electrical vitality converts to mechanical
vitality, water suck by outward siphon and it goes through funnel to revolving plane which is equal associated. Rotational
stream tosses the water into plates and utensils at some weight for cleaning reason. Self-loader dishwasher joins water and
cleanser into powerful mixed drink at that point showers it against the dishes. The dishwasher at that point siphons out the
water containing food particles that have been expelled from the dishes, and washes the dishes with clean water and a flush
operator. In the wake of siphoning out the wash water, leave the dish for drying.
The following are the component of semi-automatic machine:-
1. Motor: Type: Permanent range of Magnet DC motor (Wiper Motor) In a DC motor, the armature rotates within the
magnetic field. The basic principle of DC motor operation is based on the fact that whenever a current driver is placed inside
the electric world, there will be an operating voltage that the driver is seeing. All types of DC motors operate under this
system. So to build a DC car, it is important to establish a magnetic field. The magnetic field is created by the use of a magnet.
Permanent Magnet DC motor (or PMDC motor) is a DC motor that uses permanent magnet to generate the magnetic force
required for DC motor operation.
2. Electric Water heating coil (Immersion Heater): An electric heater that is immersed in water to heat water is called
Immersion heat. On the market from 250 watt to 2.0 kilograms of watt available. The body is made of metal material, and the
heating element is made of copper inserted into the capillary tube. The tube is available in 'U' or Coil shape. The capillary tube

is filled with magnesium oxide which acts as a condenser. Both ends of the tube are tied. Provisioning connections are
provided with a 3 pin socket and plug.
3. Mini submersible water pump: Sub pump (electric motor (ESP)) is a tool with a small motor that is locked and closed near
the pump body. The whole assembly is concentrated in the liquid to be sprayed. The main advantage of this type of pump is
that it prevents the pump holes, a problem associated with the large height difference between the pump and the water
reservoir. Groundwater pumps inject fluid into the surface unlike jet pumps that create space and are subject to atmospheric
pressure. Liquids, accelerated by the impeller, lose their kinetic energy in the diffuser when the kinetic transition to the energy
is realized. This is the main operating system for radial pumps and mixed braking.
4. Bearings: Type Pillow block bearing support typically refers to housing with associate degree enclosed anti-friction
bearing. A support refers to any mounted bearing whereby the mounted shaft is in an exceedingly parallel plane to the
mounting surface, and perpendicular to the centre line of the mounting holes, as contrasted with numerous styles
of projection blocks or projection units. A support might contain a control with one amongst many styles
of rolling components, together with ball, cylindrical roller, spherical roller, tapered roller,
or argentiferous or artificial bushing. the kind of rolling part defines the kind of support. These take issue from "Plummer
blocks" that are bearing housings provided with none bearings and typically meant for higher load ratings and a singly put
in bearing.
5. Sprocket Wheel A sprocket or sprocket-wheel is a spare wheel with teeth, or screws that is made of chain, track or other
fuel. The term 'sprocket' applies generally to any wheel where the radial radius intersects the chain passes through it. It is
distinguished by the gear that the sprockets have not meshed together directly, and differs from a pulley in that sprockets have
teeth and pulleys are smooth except for timing pulleys used with toothed belts.
8. Discharge Nozzle: Adjustable Type (Adjustable) Nozzle is a tool designed to control the direction or characteristics of
water flow (especially to increase speed) as it exits (or enters) a closed chamber or pipe. The nozzle is usually a pipe or tube of
a different geographical area, and has been used to direct or adjust the flow of water (fluid or gas). Nozzles are frequently used
to control the flow rate, speed, direction, weight, composition, and / or pressure of the source. For Nozzle, the speed of a liquid
increases without the cost of its compressive strength.
9. Chain Drive: Chain drive transfer the power from Ac motor to Shaft .Chain drive is a way of transmitting mechanical
power from one place to another. It is often used to convey power to the wheels of a vehicle,
particularly bicycles and motorcycles. It is also used in a wide variety of machines besides vehicles.
10. Utensils Grill: Utensil Grills utilized in self-loader dish washer is to convey the quantity of plates, Bowls, cup, spoons and
other utensil for washing reason. It comprises of SS (Stainless steel) It is effectively accessible and ease. For bigger and
heavier things, for example, plates, serving platters, pans, bowls, and so on., upper flame broil utilized. Glasses, cups and little
things, for example, saucers can likewise be put in the lower bin. At the point when inclined, plates up to 35 cm in
measurement can be suited. Multi Comfort Zone The back area of the lower bushel is utilized for washing cups, glasses, plates
and pots. Pivoted spikes The spikes at the front are utilized for washing plates, soup bowls, platters, dessert bowls, and saucers.
The spikes can be brought down to make more space for huge things, for example pots, skillet and dishes.
11. Body Support: Material: Sheet metal Thickness = 2 mm and Nuts, bolts and washer.
Working Principle of Semi Automatic Utensils Washing Machine
The working rule of the Utensils washer is to give the mechanical activity important to disseminate and coordinate the cleanser
arrangement and flush waters over, under and around the dishes to slacken and expel oil. The dishwasher should likewise expel
oil-loaded waters from the machine after each period of the cycle and give drying of dishes after the cleaning procedure has
been finished. The engine is combined with the pivoting plate by sprocket and chain system. The pole turn relies on the
revolution of engine by sprocket chain system. The high constrained water is splashed to the turning plate by water siphon.
This is a straightforward sort of semi-mechanization venture.

Torque = Force x Perpendicular distance
Force = (Load applied on the rack + Mass of shaft) x Gravitational force
Let assume, the average load applied on the rack will be 10kg, the mass of rack will be 4kg and mass of shaft be 1kg.
Force = (10 + 4 + 1) x 9.81 = 147.15N
Perpendicular distance = 20cm = 0.2m
Torque = 147.15 x 0.2 = 29.48
Power = 0.0771kW = 0.10hp
Therefore, select standard motor as 0.5hp
Design Calculation of Jet
There is the condition as the vertical plate is considered for ascertaining the power applied by the fly on the dishes and utensils.
Power applied by the fly on a fixed vertical plate: The fly subsequent to striking the plate, will move along the plate, as the
plate is at right points to the stream, the fly will be diverted through 90 degree. Henceforth the segment of the speed of fly,
toward fly, in the wake of striking will be zero.
Consider, V = Velocity of the jet
D=diameter of the jet,
A = area of cross-section of the jet
= π/4 d2
We know,
mass/sec = ρ * A * V
Fx = ρ *A * V (V-0)
Fx= ρ A V2
The value of density (ρ) of water = 1000 kg/m3
We have,
d = diameter of jet = 200 mm = 0.02m
a) Area of jet A = π/4 d2
= π/4 (0.02)2= 3.14x10ˉ4 m2
b) Flow rate Q = 30 lit/min
= 5x10ˉ5 m3/s
Since there are four jets, the flow rate is divided by 4
Q1=Q2=Q3=Q4= 1.25x10ˉ5 m3/s
c) Velocity of jet Q = A x V
1.25x10ˉ5= 3.14x10ˉ4 x V V=0.0398 m/s
d) Force exerted by jet F = ρaV2
= 1000 x 3.14x10ˉ4x 0.03982 = 4.9738 x 10ˉ4N
We know that,
e) Pressure required through jet Pressure (P) = F/A =4.9738 x 10ˉ4/ 3.14x10ˉ4 P = 1.5840 N/m2 or bar
