Benefits of technology

[0019]An object of the present invention is therefore to provide a solar cooker that is free from the dual constraints of solar concentration and solar orientation.
[0020]Another object of the present invention is to provide a solar cooker of simple and aesthetic design, in the form of a self-contained cooking pot, requiring no additional parts or accessories for its normal operation.
[0021]Another object is to provide a user-friendly solar cooking pot of simple construction, requiring no assembly or setup, and immediately usable out of the box, comprising only two separate components: a body and a lid...

Embodiment Construction

[0049]FIG. 1 is a front perspective view of the preferred embodiment of the solar cooking pot 10 comprising two mating parts shown separated, a body 10A and a lid 10B. Body 10A is a double walled container composed of two material layers, a metal liner 12A and a transparent plastic shell 14A, separated by a vacuum insulation layer 16A. Lid 10B is similarly composed of two layers, liner 12B and shell 14B, separated by insulation 16B. Lip 18A is an inward projection or fold of shell 14A that engages liner 12A and forms a closure for the double wall of body 10A, sealing its vacuum space 16A. Lip 18B similarly forms a closure for lid 10B, enclosing its vacuum gap 16B. A thermometer 20 is mounted on liner 12A, within vacuum gap 16A. The display screen and indicator on thermometer 20 includes glow-in-the-dark indicia for ease of temperature reading in the absence of ambient light.

[0050]FIG. 2 is a left cross-sectional view of pot 10, with lid 10B fitted on body 10A by apposing closures 18...

Abstract

A solar cooker in the form of a pot with double-walled body and lid configured to collectively constitute a near-hermetic thermal enclosure including a closed, solar radiation-absorbing and heat-retaining vessel surrounded by a vacuum insulation shield encased in a transparent peripheral jacket. The device intercepts solar energy omnidirectionally, and collects and retains it with sufficient efficiency to pasteurize water and cook food without resorting to outside reflectors, refractors, conductors, or insulators, thereby escaping from the dual requirements of solar concentration and orientation that universally govern the construction and operation of existing solar cookers. Freedom from these restrictions enables designs that are inexpensive, simple, compact, lightweight, sturdy, accessible, and applicable in varied geographic, climatic, economic, social, and culinary contexts.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of provisional application Ser. No. 61 / 001,607 filed Nov. 1, 2007.BACKGROUND OF THE INVENTION[0002]1. Field of Invention[0003]This invention relates to cooking devices, and more specifically to solar cookers.[0004]2. Description of Prior Art[0005]Solar cookers come in a myriad of designs from different historical eras and various geographic parts of the world, and proponents of solar cooking have devised schemes for classifying the many models and their variants, as discussed on the website, solarcooking.wikia.com / wiki / compendium_of_solar_cooker_designs. At the most basic level, among solar cooking devices in common use, one can distinguish three types: the solar oven, the solar panel cooker, and the solar stove. The term “solar cooker” is used to refer to any type of solar cooking device, including the above and less common indirect cookers.[0006]In a solar oven, direct and, optionally, reflected solar...
