Abstract

A thawing appliance ( 1 ), in particular a food thawing cabinet, includes a food compartment ( 11 ), a refrigeration circuit ( 30 ) comprising a cooler ( 37 ), a heater ( 40 ) switchable between at least two conditions, and an air circulating element ( 21 ) circulating an airflow across the food compartment ( 11 ). The airflow passes through the heater ( 40 ) only a part of the airflow passes through the cooler ( 37 ).

Claims (22)

1. A thawing appliance, comprising:

a food compartment;

a refrigeration circuit comprising a cooler;

a heater switchable between at least two conditions;

an air circulating element circulating an airflow across the food compartment; and

an airflow path that passes the airflow entirely through the heater, and passes only a part of the airflow through the cooler.

2. The thawing appliance of claim 1 , wherein the air circulating element is switchable between at least two conditions.

3. The thawing appliance of claim 1 , wherein the refrigeration circuit is switchable between at least two conditions.

4. The thawing appliance of claim 1 , wherein the airflow circulated by the air circulating element follows a same airflow path within an air processing compartment during a thawing mode and a holding mode of the appliance.

5. The thawing appliance of claim 1 , wherein a portion of a suction aperture of the air circulating element faces a major face of the cooler.

6. The thawing appliance of claim 5 , wherein the cooler is not centered on the air circulating element.

7. The thawing appliance of claim 6 , wherein the cooler and the air circulating element each have a horizontal axis, and are mutually arranged so that only the upper part of the suction aperture of the air circulating element forces air through the cooler, while the lower part of the suction aperture of the air circulating element directly intakes the air coming from the food compartment.

8. The thawing appliance of claim 1 , wherein the air circulating element is a centrifugal fan.

9. The thawing appliance of claim 8 , wherein the centrifugal fan is arranged at a back wall of the appliance.

10. The thawing appliance of claim 1 , wherein the air path within the food compartment is of a back-to-front air path.

11. The thawing appliance of claim 1 , wherein the thawing appliance comprises a controller for controlling components of the thawing appliance.

12. The thawing appliance of claim 11 , wherein the air circulation element is a variable speed fan, controlled by the controller.

13. The thawing appliance of claim 12 , wherein the airflow of the fan is controllable by a pulse width modulation signal output by the controller.

14. The thawing appliance of claim 1 , wherein a temperature sensor is arranged within a path of the air flow circulated by the air circulating element.

15. The thawing appliance of claim 1 , comprising a displaceable fake bottom to adjust the internal volume of the food compartment to the quantity of product to be thawed and/or stored.

16. The thawing appliance of claim 1 , wherein the cooler comprises an evaporator.

17. The thawing appliance of claim 1 , wherein the airflow path includes a divider passing the part of the airflow through the cooler after the airflow has passed through the heater.
