Publication number: 20090090121Abstract: The present invention relates to a refrigerator unit and/or a freezer unit comprising a cooling tank, which includes an inner tank having a refrigerated space, and an evaporator. The present invention furthermore relates to a method of installing a refrigerator unit and/or freezer unit in which an evaporator as well as at least one further electrical and/or technical cooling functional component are inserted in an inner tank of the refrigerator unit and/or freezer unit and are fastened to an inner tank wall. Installing the various electrical and technical cooling components after one another individually at different positions of the inner tank of the unit and individually connecting them to the outwardly disposed electronics of the unit is avoided with the present invention. Already installing individual components before the foaming of the unit tank is in particular also avoided, whereby the housing handling is considerably facilitated.Type: ApplicationFiled: April 12, 2006Publication date: April 9, 2009Inventors: Josef Hecht, Jorg Huber, Hans Gross, Franz Kauk, Gunter Mack, Matthias Wiest
