Specification

Description:FIELD OF THE INVENTION
This invention relates to the field of thermal engineering, specifically to improvements in thermos flask design and functionality, incorporating advanced temperature control mechanisms and renewable energy sources. It also touches on powerline networking for data transmission and remote monitoring capabilities.
BACKGROUND OF THE INVENTION
Traditional thermos flasks rely on passive insulation methods, typically vacuum insulation and double-walled construction, to maintain the temperature of their contents. However, these methods are limited in their ability to precisely control temperature and are susceptible to external temperature fluctuations over extended periods. They lack active temperature regulation and real-time monitoring capabilities.
Existing smart thermos flasks offer digital temperature displays and sometimes remote monitoring through smartphone apps. However, these typically do not integrate active temperature control, often relying solely on the passive insulation provided by the thermos itself. This means temperature fluctuations still occur and depend significantly on external conditions. The reliance on battery power also necessitates regular charging.
The integration of Peltier modules in thermal applications is known. However, applying this technology to a thermos flask while simultaneously harnessing solar power for energy efficiency presents a unique challenge. The successful implementation requires careful consideration of energy management, thermal integration, and miniaturization of components.
Powerline communication offers a potential pathway for remote monitoring and control of the thermos flask, but integrating this technology requires robust data modulation and error correction techniques to address the inherent noise and interference characteristics of power lines. A key challenge lies in achieving reliable data transmission over electrical wiring without compromising the performance of the primary powerline function.

The thermos flask consists of a double-walled, vacuum-insulated container designed to minimize passive heat transfer. This provides a foundation for the active temperature control system.
A Peltier module is integrated into the flask's design, enabling active heating or cooling. This module's operation is controlled by a microcontroller based on temperature readings from a precisely placed temperature sensor inside the flask. The microcontroller employs a control algorithm that dynamically adjusts the Peltier module's power to maintain the desired temperature.
A solar panel embedded in the flask's exterior provides a renewable energy source for powering the system. A rechargeable battery supplements the solar power to ensure uninterrupted operation, even in low-light conditions. The energy efficiency of the design has been optimized to prolong battery life.
Optionally, the invention includes a user interface, such as a display screen or a smartphone app, allowing users to set their desired temperature, view real-time readings, and remotely control the thermos flask's operation via powerline communication. The powerline communication module uses a combination of OFDM and chaotic modulation for robust data transmission and security.
