HELIOKITCHEN Russian patent published in 1997 - IPC

FIELD: helioengineering, in particular, solar kitchens. SUBSTANCE: heliokitchen uses a radiation detector and a concentrator with an azimuth-zenith attitude control system connected to the radiation detector by means of links; the system represents a bent guide of the locking member secured in the radial groove of the concentrator, which is attached to the bed frame fixed to the base rotatable relative to the +-Z-axis, and has a bush on one end with a pin for vertical movement relative to the latter. The radiation detector is installed in the suspension assemblies of the bed frame for turning relative to their longitudinal +-Y-axis, it represents a hollow sphere of heat-insulating material with a through hole facing the concentrator, having a hinged cover with a closed-position retainer; the object to be heated is installed inside the sphere on a support connected to the bed frame suspension assemblies. Concentrator radius P_c exceeds external radius P_h of the spherical hollow detector by four times. The internal surface of the sphere has a spectrum selective coating with a high absorbing capability in the region of the maximum of the solar radiation spectrum and with a low radiating power in the region of the self-radiation spectrum. The external surface capacity with respect to the solar radiation spectrum. The locking member uses a U-shaped plate installed on the bent guide and secured in the radial groove of the concentrator, in whose side face provision is made for a threaded hole for the pressure bolt with a pipe wrench. The bed frame suspension assemblies have a bush with a pin, whose one end has a square section, and the other end with a cylindrical section has a a groove, in which the support for the object to be heated is fixed. The retainer represents a door latch with a permanent magnet. EFFECT: enhanced efficiency. 7 cl, 7 dwg
