Drying system control method and clothes processing device

Abstract

The present application relates to the technical field of drying, in particular to a method for controlling a drying system and a clothes processing device. The drying system includes a drying fan, an air inlet channel and an air outlet channel. The drying fan has an air inlet and an air outlet; The air outlet is connected to the inner cylinder, and the evaporator and condenser are arranged in the air outlet channel; the temperature and humidity sensor is installed in the air outlet channel to detect the humidity and temperature of the circulating air in the air outlet channel; The gas in the cylinder flows back to the inner cylinder through the air inlet channel, drying fan, evaporator and condenser to form a drying circuit. This application uses a temperature and humidity sensor to directly detect the humidity and temperature of the circulating air in the air passage. Compared with the solution of using a temperature sensor to detect the temperature change at the rear of the outer cylinder, the detection accuracy can be improved, so that it can accurately reflect the clothes in the inner cylinder wet and dry state.

Description

technical field [0001] The present application relates to the technical field of drying, in particular to a method for controlling a drying system and a clothes processing device. Background technique [0002] With the continuous development of science and technology and the continuous improvement of economic level, more and more users pay attention to the integrated drum washing and drying machine. [0003] At present, the vast majority of all-in-one washing and drying machines on the market are condensing. The drying method is to heat the air through the heating pipe, and the heated air is brought into the inner cylinder by the fan. After the clothes in the cylinder are heated, the moisture on the clothes Evaporated into high-temperature and high-humidity steam, the high-temperature and high-humidity steam is sucked into the exchanger, and the high-temperature and high-humidity steam condenses after being in direct or indirect contact with the cooling medium in the exchang...

Problems solved by technology

However, since the heat pump type washer-dryer does not use heating tubes to heat the air, the temperature of the air entering the inner cylinder during the drying process of the heat pump type washer-dryer is relatively higher than that of the condensing type washer-dryer during the drying process. cooler air

When the temperature sensor is used to detect the temperature change at the rear of the outer tub, the temperature change at the rear of the outer tub is not very obvious, which leads to a decrease in detection accuracy and cannot accurately reflect the dry and wet state of the clothes in the inner tub
