ABSTRACT:
In a radiant heater (1) a support tray (3) receiving the radiant heating elements (10, 11) and hotplate (4) are displaceable with respect to one another by sliding guides (27) immediately adjacent to hotplate (4) and are self-adjustably tensioned with respect to one another by tension springs that an insulating material bearing rim (9) of support tray (3) always reliably engages on the inside of hotplate (4). The thus formed, self-adjusting unit can be supported as an entity on base (6) by means of actuating spindles (31), so that its level can be adjusted at any time without impairing the engagement of support tray (3) on hotplate (4).
