Definitions

• the present invention concerns the reliable management and discharge of drip water occurring within the cabinet body and at the evaporator of refrigerated sales cabinets.
• condensate may form within the cabinet body. Also, during the defrost operation cycle of the evaporator melting water is produced. Such condensate and melting water is assembled as drip water at the bottom portion of the cabinet body. Mechanisms have been de- veloped for expelling such drip water into the environment outside the refrigerated sales cabinet, however, these solutions do not work or are not suitable for refrigerated sales cabinets with the condenser and condenser fan arranged on top of the cabinet.
• a refrigerated sales cabinet comprises: a cabinet body comprising a roof portion and a bottom portion; an evaporator arranged at the bottom portion; a condenser comprising a condenser fan arranged at the roof portion; a drip water collecting container arranged at or below the bottom portion, configured to collect water from the inside of the cabinet body; a steam conduit leading from an inlet at the drip water collecting container to an outlet at the roof portion; a heater arranged within the drip water collecting con- tainer; an ambient air fan arranged at the drip water collecting container configured to blow ambient air through at least a portion of the drip water collecting container entraining steam from the drip water collecting container and to blow such steam through the steam conduit.
