Abstract: A scent bowl may include a base having an external concave base surface and at least one sidewall extending from the base. A majority of the base and the at least one sidewall may be formed of ceramic material. A system for scenting the air in a room with scent from a scent bowl may include a scent bowl warmer configured to generate heat at a first temperature and a detachable and separate scent bowl including a base having an external concave base surface and at least one sidewall extending from the base and a scent emitter therein, the scent emitter having a fragrance and a second temperature at which the fragrance evaporates. The first temperature is high enough to evaporate at least a portion of the fragrance from the scent emitter in the bowl in less than three hours.

Abstract: An infrared heating unit for a microwave oven comprises an outer envelope in which an electrical heating coil is mounted. The heating coil comprises a series of loops. A group of loops located in a central section of the coil has a pitch interval greater than that of the loops located in end sections of the coil, whereby less heat is generated by the loops located in the central station.
