Problem Statement
- In convention dishwasher, due to various shapes of the vessels to be washed, and proximity of the vessels to be washed, the fluid jets generally get blocked & may be unable to reach soiled portions of the vessels.
- Said vessels are still not completely cleaned after a long wash cycle & such wash cycles consume plenty of water & in-turn electrical power for operation.
- Further, the wetting & washing the vessels upon scrubbing necessitates use of ample amount of cleaning fluids & further rises the amount of water required. Hence there is a need to address above issues in efficiently.
Technology
- Present invention describes a dishwashing apparatus, comprises :
- a base structured to house a first motor;
- a drum rotatably disposed on a portion of the base & connected to the first motor, the drum being configured to receive & accommodate a plurality of vessels;
- a plurality of brushes rotatably disposed on an inner surface of the drum, the plurality of brushes is configured to selectively dispense a cleaning fluid & scrub the plurality of vessels for cleaning at least some vessels of the plurality of vessels;
- at least one washing rack removably connectable to a portion of the drum, the at least one washing rack configured to receive remaining vessels of the plurality of vessels;
a displacing & spinning mechanism disposed in the drum & connectable to the at least one washing rack on one end &, other end of the displacing & spinning mechanism being connectable to the drum, the displacing & spinning mechanism being configured to displace & rotate the at least one washing rack relative to the drum;
- an indication unit connectable to at least one of the base & a cover enclosing the drum, the indication unit configured to indicate at least one signal corresponding to cleaning of the plurality of vessels (4); and
- a control unit communicatively coupled to the first motor, the plurality of brushes, the displacing & spinning mechanism and the indication unit.
- Further claimed a method of operating the dishwasher apparatus.
Key Features / Value Proposition
Technical Perspective:
Different Components:
- A) Sensors: optical level sensors, proximity sensors & continuous level sensors such as capacitive sensors, proximity sensors, non-contact level gauges, & miniature cameras,
- B) Control Unit: detect presence of the plurality of vessels in at least one of the drum & the at least one washing rack upon receiving the at least one signal corresponding to cleaning of the plurality of vessels. Finally regulates the operation of the dishwasher apparatus.
Improved Performance:
- Enhance the overall performance by taking less time for a wash cycle & may reduce amount of cleaning fluids required for washing vessels by reusing the cleaning fluids.
- Therefore, said apparatus is economical & efficient.
Experimental Results:
The apparatus may wash the plurality of vessels in a cycle time of 10 to 15 minutes.
Industrial Perspective:
Utility:
- universally applicable in Domestic & Home appliances.
