Drying system, clothes processing device and drying system control method

Abstract

The invention relates to the technical field of drying, in particular to a drying system, a clothes processing device and a drying system control method. The drying system comprises a drying draught fan, an air inlet channel and an air outlet channel, and the drying draught fan is provided with an air inlet and an air outlet; the two ends of the air inlet channel are communicated with the air inlet and an inner cylinder respectively; the two ends of the air outlet channel are communicated with the air outlet and the inner cylinder respectively; and an evaporator and a condenser are arranged inthe air outlet channel; a temperature and humidity sensor is arranged in the air outlet channel and used for detecting the humidity and temperature of circulating air in the air outlet channel; the gas in the inner cylinder flows through the air inlet channel, the drying draught fan, the evaporator and the condenser and flows back into the inner cylinder to form a drying loop. The drying system,the clothes processing device and the drying system control method have the advantages that the humidity and temperature of the circulating air in the air outlet channel are directly detected by usingthe temperature and humidity sensor, and compared with the scheme that a temperature sensor is used for detecting the temperature change of the rear of an outer cylinder, the detecting precision canbe improved, thereby accurately reflecting the dry and wet states of the clothes in the inner cylinder.

Description

technical field [0001] The present application relates to the technical field of drying, and in particular to a drying system, a clothes processing device, and a drying system control method. 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...

AI Technical Summary

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
