By the invention a technical problem of constructive device has been solved which enables automatic continuity tracking of work of electro engine compressor and conducting records about weather which it took in the regime of negative work that is, additional freezing of food in the cooling chamber. This is accomplished so that the constructive device which performed by a motor (1) timer synchronized connected round plate (2) with radial notch (3) and timer (4) as well as with a switch P1 (7) with thorns (6) on working contact K3 which are with the thermostat T tied so that it enables registration of each negative work of the cooling device, enabling continual tracking of its work and insight stage of frozen groceries. |
