ABSTRACT:
A cleaning fluid heating reservoir and motor assembly for a range hood having a motor housing enclosure mounted within the enclosure defined by the hood body. The heating reservoir is shaped and dimensioned to be in abutment with, or is integral with, the motor. The motor is mounted within the motor housing. The reservoir may occupy space between the top of the motor and the hood body, between the perimeter of the motor and a fan attached to the motor, or between both. Conduits connected to the heating reservoir inlet and outlet pass through the motor housing to an intermediate reservoir located within the range hood. Fluid from the intermediate reservoir is pumped to the heating reservoir and back to the intermediate reservoir thereby drawing heat energy from the motor when in operation. Cleaning fluid may also be pumped from the intermediate reservoir to areas requiring cleaning.
