  • Patent number: 5664936
    Abstract: A fan mounting arrangement of the type comprising a blade assembly incorporated to a tubular central hub (1, 10) fitted into a shaft end (2, 20) of a motor (M), the central hub (10) having at least one engaging projection (11) fitted into a corresponding engaging recess (21) provided at an end portion of the shaft end (20), in order to mount the central hub (10) to said shaft end (20) restraining said parts from relative movements, the fitting being obtained by the elastic deformation of part of the lateral wall of said central hub (10).

  • Patent number: 5490394
    Abstract: A fan control system for the evaporator of refrigerating appliances, of the type in which the internal air is forced to circulate, by action of a fan (20), through the evaporator (30) of a refrigerating circuit, fed by a compressor (40), the system comprising: a first temperature sensing means (S1), detecting the temperature of the circulating air at the air inlet of the evaporator (30); a second temperature sensing means (S2), detecting the temperature of the evaporator (30); and a control circuit (50), producing: a fan stop control signal, when the difference between the values of the temperatures detected by the first and second sensors (S1, S2) reaches a stop value, below which the heat transfer from the forced circulating air to the evaporator is lower than the heat transfer from the fan (20) to the air; and a fan start control signal, when the difference of temperatures reaches a certain start value corresponding to a temperature of the evaporator (30) substantially lower than the temperature of the air
