Description

FIELD OF THE INVENTION

The present disclosure relates generally to over the range kitchen appliances. In particular, the disclosure relates to over the range microwave appliances and lighting systems therefor.

BACKGROUND OF THE INVENTION

Built-in kitchen appliances, for example microwave ovens, have become commonplace in household kitchens. In many applications, a microwave is built-in over a cooktop or range. Microwaves configured in this arrangement are generally referred to as over-the-range (OTR) appliances. In many cases, OTR microwave ovens include a ventilation system to capture and redirect steam, smoke, airborne grease, or odors generated at the range.

OTR appliances are limited in the positioning of ancillary systems, such as lighting systems. For instance, lighting systems are challenged to avoid ventilation systems, such as to avoid obstruction of ventilation openings. Kitchen cabinets further limit positioning of a lighting system.

Accordingly, an OTR microwave and system addressing one or more of these issues would be beneficial and advantageous.
