Abstract
A device for inspecting the heat insulation of household appliances, more particularly refrigerators, includes a traditional thermographic apparatus for detecting the thermographic images of the insulation by use of the exothermic reaction produced during foaming of the insulation and a control and processing unit, known per se, connected to the thermographic apparatus, possibly to a monitor, and to an input unit. The control and processing unit contains coded data corresponding to the conditions under which the heat insulation is properly produced, such data being compared with that produced by the thermographic apparatus and corresponding to the effective condition of the heat insulation of each applicance produced. Depending on this comparison, the unit proceeds to control the forward movement of a conveyor device so as to enable the appliances to be assembled, repaired or replaced.
