Abstract
An evaporation tray for a refrigerator or refrigerator/freezer which is adapted in use to contact a heat producing part of the refrigeration system (such as the compressor or condenser). The tray comprises a rigid frame which supports a flexible membrane designed to receive defrost liquid from the refrigerator or refrigerator/freezer. The frame is designed to sit adjacent the heat producing part so that the flexible membrane is in direct contact with the heat producing part. As the membrane is flexible, it easily deforms to the shape of the heat producing part providing increased heat transfer to liquid in the tray.
Claims16
Liquid collection and evaporation means for refrigeration equipment adapted to collect liquid produced during the operation of said refrigeration equipment, said refrigeration equipment having a heat producing means with a heated surface, said liquid collection and evaporation means comprising:
- substantially rigid frame means adapted for positioning adjacent said heated surface and forming a peripheral support which defines at least the extremities of a substantially horizontal opening, and
- flexible tray forming membrane means suspended at its periphery from said peripheral support, enclosing the space below said opening, said membrane assuming a tray shape capable of holding at least a predetermined volume of said liquid and adapted to contact and deform to the shape of said heated surface to enable heat to pass there through to evaporate said liquid.
Refrigeration equipment comprising:
- a refrigeration system which, when operational extracts heat from within said refrigeration equipment, including a heat producing means which upon energisation produces heat, said heat producing means having a surface which is heated by at least some of said heat produced by said heat producing means,
- cabinet means containing at least one cooling compartment which is cooled due to the operation of said refrigeration system, said at least one cooling compartment on occasion producing a liquid flow due to the operation of said refrigeration system,
- liquid channeling means which collect said liquid flow from within said at least one compartment and direct said liquid flow outside said at least one cooling compartment, said liquid channeling means having an outlet outside said compartment through which collected said liquid flow is directed and
- liquid collection and evaporation means having
- substantially rigid frame means adapted positioned adjacent said heated surface of said heat producing means and forming a peripheral support which defines at least the extremities of a substantially horizontal opening configured to receive liquid discharged from said outlet of said liquid channeling means, and
- flexible tray forming membrane means suspended at its periphery from said peripheral support, enclosing the space below said opening, said membrane assuming a tray shape capable of holding at least a predetermined volume of said liquid and adapted to contact and deform to the shape of said heated surface to enable heat to pass there through to evaporate said liquid.
Liquid collection and evaporation means for refrigeration equipment adapted to collect liquid produced during the operation of said refrigeration equipment, said refrigeration equipment having a heat producing means with a heated surface, said liquid collection and evaporation means comprising:
- a first supporting frame means adapted for attachment to said refrigeration equipment adjacent said heat producing means, and
- a second interconnecting membrane supporting means removably supported on said first supporting frame means, said first supporting frame means and said second interconnecting membrane supporting means together forming a substantially rigid frame means, and
- a flexible tray forming membrane means suspended from said second interconnecting membrane supporting means, which forms a tray shape capable of holding at least a predetermined volume of said liquid and adapted to contact and deform to the shape of said heated surface to enable heat to pass there through to evaporate said liquid.
Refrigeration equipment comprising:
- a refrigeration system which, when operational extracts heat from within said refrigeration equipment, including a heat producing means which upon energisation produces heat, said heat producing means having a surface which is heated by at least some of said heat produced by said heat producing means,
- cabinet means containing at least one cooling compartment which is cooled due to the operation of said refrigeration system, said at least one cooling compartment on occasion producing a liquid flow due to the operation of said refrigeration system,
- liquid channeling means which collect said liquid flow from within said at least one compartment and direct said liquid flow outside said at least one cooling compartment, said liquid channeling means having an outlet outside said compartment through which collected said liquid flow is directed and
- liquid collection and evaporation means having
- a first supporting frame means adapted for attachment to said refrigeration equipment adjacent said heat producing means, and
- a second interconnecting membrane supporting means removably supported on said first supporting frame means, said first supporting frame means and said second interconnecting membrane supporting means together forming a substantially rigid frame, and
- a flexible tray forming membrane means suspended from said second interconnecting membrane supporting means, which forms a tray shape held in position by said second interconnecting membrane supporting means to receive liquid discharged from said outlet and capable of holding at least a predetermined volume of said liquid, said membrane means contacting said heated surface and conforming to the shape thereof to enable hat to pass there through to evaporate said liquid.
