Description
Technical Field
The present application relates to the field of drying technologies, and in particular, to a drying system control method and a laundry processing apparatus.
Background
With the continuous development of science and technology and the continuous promotion of economic level, more and more users pay attention to the drum-type washing and drying integrated machine.
At present, most washing and drying integrated machines in the market are of a condensing type, the drying mode is that air is heated through a heating pipe, the heated air is brought into an inner barrel by a fan, after articles in the barrel are heated, moisture on the articles is evaporated into high-temperature high-humidity steam, the high-temperature high-humidity steam is sucked into an exchanger, the high-temperature high-humidity steam is condensed after being directly or indirectly contacted with a cooling medium in the exchanger to become condensed water, and then the condensed water flows out along the inner wall of the exchanger. This drying mode allows the air entering the drum to be at a relatively high temperature (typically greater than 100 c). Therefore, a temperature sensor is commonly used to detect the dry and wet state of the laundry in the drum. Specifically, the temperature sensor is arranged at the rear part of the outer barrel, the temperature of the rear part of the outer barrel is higher due to the fact that the temperature of air entering the inner barrel is higher, and the temperature sensor indirectly reflects the dry and wet state of clothes in the inner barrel by detecting the temperature change of the rear part of the outer barrel. But the working power of the heating pipe is larger, so that the power consumption of the washing and drying integrated machine is also larger. And at present, most condensing washing and drying integrated machines use water as a cooling medium, so that the water consumption is large.
Therefore, from the viewpoint of saving electricity and water, the heat pump type washing and drying all-in-one machine is receiving more and more attention. However, because the heat pump type washing and drying all-in-one machine does not use the heating pipe to heat the air, the temperature of the air entering the inner cylinder in the drying process of the heat pump type washing and drying all-in-one machine is lower than that of the air entering the inner cylinder in the drying process of the condensation type washing and drying all-in-one machine. When the temperature sensor is used for detecting the temperature change of the rear part of the outer cylinder, the temperature change of the rear part of the outer cylinder is not obvious, so that the detection precision is reduced, and the dry and wet states of the clothes in the inner cylinder cannot be accurately reflected.
