Ice level probe (4) for an ice maker machine comprising an evaporator of a refrigerating unit and an ice-collecting bin (3) in which a said ice level probe (4) is positioned, comprising at least one temperature sensor (5) connectable to an electronic control card (7) that comprises Joule effect heating means (6) connectable to said electronic control card (7), wherein said heating means (6) comprise at least one electrical resistance (6'), the thermal power that can be delivered by said heating means (6) being calibrated so as to be sufficient to maintain the probe (4) in thermal equilibrium in free air but insufficient to maintain the probe in thermal equilibrium with solid or melting ice, characterized in that said heating means (6) comprise at least one LED (6") and characterized also by the fact of comprising a tubular casing (8) containing a resin based embedding mean (9, 10) with high thermal conductivity, in which said heating means (6) and said temperature sensor (5) are embedded, said embedding means (9) being transparent at least around said LED (6") and said tubular casing (8) being made from a material suitable for diffusion of the light generated by said at least one LED (6") that advantageously performs the dual function of heat sink and illuminator of the ice, so as to provide the user with a precious visual indication of the presence of ice in the bin (3) at the desired level reached. |
