Embodiment Construction
[0020] FIG. 1 shows a perspective view of a defrost heater designed in the form of a tube heater, which comprises a first heating device 10 and a second heating device 50 . FIG. 3 shows the arrangement of FIG. 1 with fan 30 in an end view. As can be seen from FIG. 2 , the first heating device 10 is constituted by a meander-shaped tube heater 12 extending parallel to the front and rear sides of the evaporator 20 . The second heating means 50 is constituted by a helical section 52 of a tubular heater. The heating means 10, 50 are part of the same tube heater and are therefore in fluid communication through a heating medium flowing through.

The invention relates to a refrigerating and / or freezing appliance, especially a refrigerator, an upright freezer or a chest freezer, said appliance comprising an evaporator for cooling air, a ventilator (30) for supplying the cooled air into the inner chamber of the refrigerating and / or freezing appliance, and a first heating device (10) for defrosting the evaporator (20). A second heating device (50) is arranged in such a way that, during the operation of the second heating device (50), the temperature of the surface of the ventilator is above the dew point of the air in the region of the ventilator (30), at least in certain areas.
Description
technical field [0001] The present invention relates to a refrigeration and / or freezing appliance, in particular a refrigerator, an upright freezer or a chest freezer, comprising an evaporator for cooling air, for feeding cold air into the interior of the refrigeration and / or freezing appliance A fan, and a first heating device for removing ice formed on the evaporator. Background technique [0002] Such a refrigeration and / or freezing device is known, for example, from DE 19645182 A1. In the case of refrigeration and / or freezing equipment in which the evaporator is arranged in the refrigerated space, and whose evaporator is arranged outside the refrigerated space, such as in a refrigerated channel separated from the refrigerated space by a partition, refrigeration and / or refrigeration In the case of refrigeration or refrigeration equipment, there is the problem of ice forming on the evaporator over time, which adversely affects its operating performance or refrigeration ca...
