ものとなり、周囲条件の影響を排除できる。As described above, according to the method for setting and displaying the drying operation time of the clothes dryer of the present invention, firstly, until the exhaust temperature rises by the temperature difference value set based on the ambient temperature. Since the time is measured and the subsequent drying time is set using this operation elapsed time as an element, the set drying operation time is determined not only by the exhaust temperature but also by the ambient temperature, eliminating the influence of ambient conditions. it can.
【００３８】第２に、設定された乾燥運転時間を表示

れるものである。Thirdly, the temperature difference value set on the basis of the ambient temperature is provided in a plurality of stages, and the drying operation time is determined by the average value of each elapsed time until the exhaust temperature reaches the temperature of each stage. Thus, the accuracy of detection of the elapsed time until the exhaust gas temperature rises to the set temperature, which is an element for determining the drying operation time, is improved, and a more appropriate drying operation time is obtained.
