Introduction
Dishwashers are a common household appliance designed to
automate the process of cleaning dishes. However, many users
face issues such as ineffective cleaning, energy and water
consumption, user interface and experience with the performance
and convenience of their dishwashers, leading to dissatisfaction
and inefficiency. Designing a robotic dishwasher involves creating
a system that integrates robotics with dishwashing technology to
automate the cleaning process which can overcome all the
drawbacks in traditional dishwasher
Principles Used
Mechanical Chemical
Soaking in hot water Time
Process
Mechanical:Food will be scraped off, washed with hot, soapy
1. water, rinsed thoroughly, and air dried or towel dried.
Chemically:Chemically washing dishes involves using detergents,
2. which are surfactants that reduce surface tension, allowing
water to penetrate and lift away food particles.
Soaking in hot water:The hot water used in the process
3. accelerates the chemical reactions, aiding in the cleaning
process.
Time:Soaking dishes before washing is beneficial as it softens
4. and loosens food particles, making them easier to remove with
less scrubbing. This reduces the risk of scratching cookware and
saves time and energy.
