AI Technical Summary
Technical Problem
Small items of clothing are easily blown towards the vents by the fan in a tumble dryer, resulting in uneven heating, which affects drying efficiency and may damage the clothes.
Method used
The temperature inside the inner drum is detected multiple times using an infrared temperature sensor. By analyzing the temperature matrix data, undried areas are identified, the probability of undried areas is calculated, the type of clothing is determined, and a suitable small-load drying program is selected.
Benefits of technology
It achieves accurate identification and even drying of small garments, avoiding overheating, protecting garment materials, saving energy, and reducing damage.

Abstract
This invention provides a drying control method and a garment processing device, applicable to a garment processing device with a drying function. The garment processing device includes an inner drum. During initial heating, an infrared temperature sensor is used to repeatedly detect the temperature inside the inner drum, obtaining multiple sets of temperature data. The area corresponding to the low temperature point in the temperature data that is lower than a preset temperature is defined as an undried area. The probability of an undried area appearing is calculated based on the multiple undried area detection results. When the probability of an undried area appearing is lower than a reference probability, a small-item load drying program is used to process the garments. This invention utilizes infrared temperature detection to identify the probability of an undried area appearing, identifies the garment type based on the probability of an undried area appearing, and identifies the garment as a small item when the probability of an undried area appearing is lower than the reference probability, thus using a small-item load drying program to prevent small items from being blown out of the inner drum, protecting the material and appearance of the small items.
