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.
  • Such refrigerated sales cabinet reliably collects all the drip water from within the cabinet body and particularly also from the evaporator, including melting water which is produced during the defrost operation of the evaporator, and condensate which forms within the cabinet body during the normal cooling operation of the evaporator, within the drip water collecting container which is arranged at/or below the bottom portion cabinet body.
  • the formation of mold or unpleasant smells which may be caused by collecting drip water within the cabinet body are reliably avoided. Also, corrosion can reliably be prevented.
  • a steam conduit leading from an inlet at the drip water collecting container to an outlet at the roof portion close to the condenser fan, a heater arranged within the drip water collecting container, and an ambient air fan arranged at the drip water collecting container are provided.
  • the heater heats up the drip water within the drip water collecting container such that at least a portion of such drip water is evaporated to form steam.
  • the ambient air fan blows ambient air through at least a portion of the drip water collecting con- tainer. Steam forming and formed within the drip water collecting container is entrained by the ambient air and blown through the steam conduit.
  • the steam conduit can particularly be formed as a sealed piping leading from an inlet at the drip water collecting container to an outlet at the roof portion close to the condenser fan.
  • the condenser fan can be used to blow and spread steam coming from the drip water col- lecting container into the environment outside the refrigerated sales cabinet.
  • the condenser fan can have an additional function, in addition to its function to blow ambient air over the coils of the condenser.
  • a refrigerated sales cabinet according to exemplary embodiments of the in- vention is suitable for all kinds of refrigerated sales cabinet employing a condenser and a condenser fan at the roof portion thereof, it is particularly well suited for so called plug-in refrigerated sales cabinets and particularly plug-in refrigerated sales freezer cabinets having the particular configuration comprising a compressor ar- ranged at the roof portion, wherein the compressor, the condenser, an expansion device and the evaporator are connected to form a vapor compression cycle.
  • the present invention is particularly suited for a refrigerated sales cabinet of the type wherein the compressor is not arranged at the bottom of the cabinet, but rather on top of the cabinet body, and where accordingly heat of the compressor cannot be used to discharge drip water from the bottom portion of the refrigerated sales cabinet, or where neither a hot gas pipe of the compressor for evaporating such drip water nor a water pump are available or feasible. .
  • the combination of the drip water collecting container, the steam conduit, the heater and the ambient air fan is very robust.
  • drip water collected within the drip water collecting container is heated up by the heater such that at least a portion of the drip water is evaporated to form steam.

  • Such steam is blown through the steam conduit.
  • the steam exits the steam conduit through an outlet at the roof portion thereof, particularly close to the condenser fan.
  • the con- denser fan can be used to blow and spread such steam into the environment out- side of the refrigerated sales cabinet.
  • the condenser fan is con- figured to blow steam exiting the steam conduit into an outside environment.
  • the condenser fan can have a rearward blowing direction and the outlet of the steam conduit can be located behind the condenser fan(s).

  • the depth dimension is defined as the direction from the front of the refrigerated sales cabinet to the rear of the refrigerated sales cabinet
  • the lateral direction is the perpendicular direction to both the depth direction, from, a left side of the refrigerated sales cabinet to the right side of the refrigerated sales cab- inet, and perpendicular to the vertical, i.e., height direction.
