DRYING MACHINE, MOISTURE CONTENT ESTIMATION DEVICE, AND MOISTURE CONTENT ESTIMATION PROGRAM

To provide a technology for estimating more precisely moisture content contained in an object to be dried.SOLUTION: A washing and drying machine 50 comprises a rotary tub 1 which accommodates an object to be dried, a heater 17 which applies heat to the object to be dried accommodated in the rotary tub 1, an irradiation unit which irradiates electromagnetic waves having a plurality of different frequencies to the rotary tub 1, a detection unit disposed between the irradiation unit and the rotary tub 1 which detects the intensity of reflection waves reflected from the rotary tub 1, and a moisture content estimation device which estimates the moisture content contained in the object to be dried accommodated in the rotary tub 1, based on the intensity of the reflection waves detected by the detection unit.SELECTED DRAWING: Figure 11 【課題】乾燥対象物に含有される水分の量をより精確に推定する技術を提供する。【解決手段】洗濯乾燥機５０は、乾燥対象物を収容する回転槽１と、回転槽１に収容される乾燥対象物を加熱するヒータ１７と、異なる複数の周波数の電磁波を回転槽１に照射する照射部と、照射部と回転槽１の間に設けられ、回転槽１から反射された反射波の強度を検知する検知部と、検知部により検知された反射波の強度に基づいて、回転槽１に収容された乾燥対象物に含有される水分の量を推定する水分量推定部と、を備える。【選択図】図１１
