Portable solar water heater

A combined table and solar water heater comprising:

• a collapsible casing, a solar collector with inlet and outlet means in said casing;
• at least a pair of containers in said casing for feeding liquid to be heated by said solar collector and for receiving liquid heated by said solar collector respectively;
• supporting means for one of said containers;
• and supporting means for enabling said casing means to be converted into a table by attaching it to said casing.

A combined table and portable solar water heater comprising:

• a rigid casing formed by a pair of hinged halves with locking means and a handle;
• a solar collector in each of said halves, said collector consisting of a solar radiation absorbing surface on the exposed side of a plate made of a material having high temperature conductivity and a pipe coil on the other side opposite to said exposed side, said coil being in a temperature-transferring relationship with said plate, a temperature-insulating layer between said opposite side and the inner surface of the wall of said casing, said wall being hinged to the frame of said casing and being provided with locking means for closing and opening said wall in order to provide access to said temperature-insulating layer, said layer consisting of a plurality of separate membranes, each of which is smaller than the opening formed by said wall in its open position;
• at least one layer of a transparent material such as a plastic film which is spaced from said exposed surface of said collector and covers said exposed surface to seal said space between the transparent material and said exposed surface, both of said collectors being interconnected in series by a flexible pipe, said casing being provided with at least one compartment for accessories, at least four legs for supporting said solar water heater, means in said casing for attachment of said supporting legs to said casing, at least a pair of collapsible containers made of a water-impermeable material, means for supporting one of said collapsible containers at an elevated level with respect to said collectors, means in said casing for rigidly interconnecting said halves into an integral rigid frame in an open position of said casing, whereby said legs and said container supporting means can be retained, during transportation and storage of said solar water heater, in said compartment for accessories, and inlet means on one of said collectors and outlet means on the other of said collectors.
