Abstract:
The present invention provides a solar-based multipurpose utility system which is an integrated appliance that uses solar energy to perform various utility functions such as cooking, ice melting, water heating, room heating, and food drying. The phase change material has been used in the system for enhancing the thermal storage capacity of the system. The invention supports the idea of providing wireless remote control for the overall system to the end-user using IoT-based sensors and devices. The system comprises Fresnel lens with cover (21), Fresnel lens (22), ice pot (23), water pipe (24), reflector (25), water storage tank (26), blower (13), phase change material (PCM) filled in evacuated tube arrangement (27), hot air sprayer (28), water filter (15), battery with electronic components (3), water tap (29), temperature and humidity sensor (16), exhaust fan (12), and solar panel (1).
Startup Options: ADVANTAGES OF THE INVENTION
  • The system efficiently performs various functions, covering cooking, ice melting, room heating, food drying, and water heating.
  • provides a solar-based cooking and ice melting unit using a combination of Fresnel lens for converging and concentrating sunÂ’s rays from the top and front portion of the system which allows ice storage unit and cooking pot to be heated efficiently.
  • provides rotating screw jack and hinge-based mechanism for variation of temperature by adjusting inclination or height of lens and reflector arrangement to fulfil the requirement of variable heat intensity for cooking and ice melting purpose.
  • efficiently provides a wireless control to the system through loT-based sensors and devices powered by solar panel which allows the end-user to turn on/off the system for controlling drying rate by varying rate of moisture, hot air flow rate and temperature.
