1. A refrigerator, comprising:

  • a utility chamber for cooled goods;

    a cold air channel to direct a cold air flow into the utility chamber, the cold air channel being separated from the utility chamber by a channel wall;

    a control device configured to generate a cooling signal which is received by a cooling device to cause introduction of the cold air flow into the utility chamber as long as the cooling signal is being received by the cooling device;

    a defrost heating element rendered operative by the cooling signal generated by the control device to prevent formation of condensate and/or ice when the cold air flow is fed into the utility chamber, the defrost heating element being disposed on the channel wall to prevent formation of condensate and/or ice on at least the channel wall; and

    a timing element configured to receive the cooling signal and, after a predetermined time interval, forward the cooling signal to the defrost heating element to delay operation of the defrost heating element in response to generation of the cooling signal.
