Abstract

The invention is a portable refrigerator (10) that may transition between a functional mode for use in the cold storage of food and drinks and a collapsed mode for transportation. Wheels (207) with a handle (52) opposite provide the method of transportation. The food storage space is controllably cooled by a chiller circuit (60), which may be powered by one or more solar panels (10). The device includes USB and A / C outlets (202,206) so that the device can be also be used as a power source. It may also include a lockable latch (203) to keep the refrigerator space closed. It may also include a u-shaped bar (200) on the outside so that the device can be secured to a fixed object.

Description

[0001] This application is a continuation-in-part of prior application Ser. No. 14 / 322,278 filed Jul. 2, 2014, which claimed the benefit of the filing of Provisional Application Ser. No. 61 / 842,024, filed on Jul. 2, 2013. The specification and claims of both prior-filed applications are incorporated here by reference.BACKGROUND OF THE INVENTION

[0002] The present invention relates to portable refrigeration apparatuses and methods.DESCRIPTION OF RELATED ART

[0003] Since the development of modern refrigeration systems, there has been a constant quest to improve the efficiency of these units in order to reduce size. Improvements in efficiency did transpire and the systems that are offered today are vastly improved over those in existence in the early 1900s. Advances in coolant chemistry and technology, in condenser and evaporator systems, and in the materials used to provide the insulated housing have all contributed to designs for coolers, refrigerators, chiller systems, and the like.[0004...
