This patent describes a clever, compact solar device designed to heat things like food or water using sunlight, perfect for homes, especially smaller apartments. It's built with two main parts: an inner container where you put what you want to heat, and an outer clear shell that covers it. The unique part is the space between these two shells, which is sealed and holds a medium (like air). This medium acts like an insulating blanket, trapping the sun's heat inside the inner container, much like a mini-greenhouse. You can easily attach this device to a window or a wall, or even use it freestanding, making it super versatile for urban living where space is tight. It also has a special coating inside to absorb more sunlight and even a knob to control the temperature. This design aims to make using solar energy for everyday heating and cooking much more practical and accessible.

Conventional solar cookers often require a large amount of space for deployment, making them impractical for use in modern compact apartments and high-rise buildings. Additionally, many traditional solar cookers require continuous manual tracking of the sun's movement throughout the day to ensure maximum efficiency, which is inconvenient. This patent addresses these limitations by offering a more compact and versatile solar appliance design.
- Compact, Dual-Shell Design: The appliance features an inner shell for heat absorption and an outer shell, creating a compact unit suitable for limited spaces.
- Insulating Gap Provision: An air-tight gap between the inner and outer shells allows for the circulation of a medium (air or non-inflammable, non-reactive fluid/gas). This gap acts as an insulator, creating a greenhouse effect to conserve heat inside the inner shell, improving efficiency.
- Radiation Absorbing Coating: The platform within the inner shell is coated with a radiation-absorbing material to maximize sunlight absorption and heating.
- Temperature Control: A temperature control knob allows for the controlled release of the insulating medium from the inner shell, enabling users to regulate the internal temperature.
A compact, dual-shell solar appliance designed to efficiently heat contents using sunlight, specifically addressing space limitations in urban homes. It features an outer transparent shell and an inner shell with a radiation-absorbing platform to maximize heat absorption. A crucial element is the airtight gap between the shells, which creates an insulating greenhouse effect, maintaining high internal temperatures. The design includes mounting flanges for easy window or wall attachment, or it can be used freestanding. A temperature control knob allows for adjusting the heat inside by releasing the insulating air.
The solar appliance is a developed concept, ready for prototyping and testing. Its design is optimized for practical implementation, awaiting further refinement and market introduction.
