Abstract
An over-the-range microwave oven including a duct unit configured to direct air from the back of the oven to the front and further includes an integrated duct module. The duct unit includes: a first panel at the bottom, a pair of second panels forming both lateral side surfaces of the duct unit. Water vapor generated from food being cooked flows along an enclosed flow path and thus is unaffected by the exhaust air flow. A humidity sensor is disposed on the first panel and operable to detect water vapor in the cooking unit.

An over-the-range microwave oven comprising:
- a housing defining an exterior;
- a cooking unit disposed in the housing;
- a duct unit disposed in the housing;
- a first panel dividing the duct unit into an upper duct and a lower duct;
- a pair of second panels forming lateral sides of the upper duct;
- a filter;
- a humidity sensor disposed on the first panel,
- wherein the housing comprises a partition wall vertically partitioning an interior of the housing into the cooking unit and the duct unit, wherein the partition wall comprises a water vapor discharge portion for water vapor flowing out of the cooking unit, wherein the duct unit comprises an upper duct unit disposed between the housing and the cooking unit and is located on an upper side of the cooking unit, wherein the first panel is spaced apart from an upper side of the partition wall and forms a bottom surface of the upper duct unit, wherein the second panels are disposed between the first panel and the housing and form the lateral side surfaces of the upper duct unit, wherein a gap between the second panels decreases in an air flow direction, and wherein further the humidity sensor is disposed on the first panel and spaced apart from one panel of the second panels;
- and
- a third panel disposed on a rear side of the pair of second panels and comprising an air inlet hole;
- and
- a fourth panel disposed outside one of the pair of second panels,
- wherein the pair of second panels comprises:
- a pair of first horizontal portions respectively disposed on two sides of the third panel and positioned in parallel to each other;
- a pair of inclined portions respectively extending from the pair of first horizontal portions, wherein interval gap between the pair of inclined portions gradually decreases;
- and
- a pair of second horizontal portions respectively extending from the pair of inclined portions and disposed in parallel to each other,
- wherein the filter unit is disposed on the pair of second horizontal portion.
