Appliance with a vacuum-based reverse airflow cooling system using one fan
First Claim
1. An appliance comprising:
- a housing having an airflow channel in flow communication with outside of the appliance;
a first chamber disposed in the housing and having a first opening;
a first door for selectively closing the first opening, the first door having a first airway in flow communication with the outside of the appliance;
a second chamber disposed in the housing and having a second opening;
a second door for selectively closing the second opening, the second door having a second airway in flow communication with the outside of the appliance; and
a fan disposed in the airflow channel,wherein the airflow channel comprises a central segment disposed between the first and second chambers and in flow communication with the first and second airways, andwherein when activated, the fan draws ambient air from the outside of the appliance through the first airway and the second airway in a direction toward the central segment and then through the central segment to cool the first door and the second door with the ambient air before the air enters the central segment.

Abstract
An appliance includes a housing having an airflow channel communicating with outside of the appliance; a first chamber in the housing and having a first opening; a first door for selectively closing the first opening, the first door having a first airway communicating with the outside of the appliance; a second chamber in the housing and having a second opening; a second door for selectively closing the second opening, the second door having a second airway communicating with the outside of the appliance; and a fan in the airflow channel. The airflow channel includes a central segment disposed between the first and second chambers and communicating with the first and second airways. When activated, the fan causes ambient air to pass through the first and second airways before entering the central segment so that the first and second doors are cooled off by the ambient air.
