KR960023456A - Automatic Drying Apparatus and Method of Clothes Dryer - Google Patents

Abstract

The present invention relates to an automatic drying apparatus and method for a clothing dryer, and the conventional clothing drying method using a temperature sensor and a humidity sensor requires a lot of sensors, which is expensive, and a temperature sensor to solve the problem of having to compensate the ambient temperature. Instead, the pressure sensing unit detects an electrical signal generated by mechanical stress caused by thermal change caused by hot air of low temperature and low humidity that enters the drum through the dehumidifying flow path and enters the drum through the dehumidification passage and cold air sucked into the dryer. Determination of abnormality of the pressure sensing unit to determine the abnormality of the pressure sensing unit in the state that the motor is turned on and the heater is turned off after inputting power using a drying device configured by adding a signal processing means for processing the electrical signal detected by the sensing unit. If there is no abnormality in the process of judging whether there is an abnormality in the pressure sensing unit, preheat the heater for a certain time. The first reference voltage judging process for determining whether the first reference voltage, which is the time when steam is generated, and the increase in water vapor for a predetermined reference time after determining the quantity of capacity when the first reference voltage is reached by the first reference voltage judging process The second reference voltage judging process for determining whether the second reference voltage, which is the point of decreasing time, and the second reference voltage judging process, and the second reference voltage judging process, has been made the first reference voltage a predetermined number of times to detect whether there is noise while water vapor is being reduced? It is possible to further improve reproducibility and drying performance by turning off the heater and then performing a complete drying process to complete drying by turning off the motor after a predetermined cooling time.
