A drying control method of a clothes dryer and a clothes dryer

Abstract

The invention discloses a drying control method for a clothes dryer and the clothes dryer. The method includes: turning on the clothes dryer, detecting in real time the temperature value T1 of the air outlet of the clothes dryer, the temperature value T2 of the heat pump system and the surface impedance value of the clothes, And the impedance value is processed to obtain the humidity value Rh of the clothes; the clothes drying program preset by the clothes dryer starts, the temperature in the clothes dryer rises, and the clothes dryer enters the clothes state test stage; in this stage, it is judged whether it is within 0 to 3 minutes. ΔT1≥5℃, and whether Rh≤A0 for 3 consecutive times; if not, the dryer enters the first drying stage, and judges whether Rh<A0 in this stage; if so, the dryer enters the second drying stage , and judge in this stage whether Rh<B0, and whether T2n‑T2(n‑1)>2℃ within 5 minutes; if so, the dryer enters the cold air wrinkle removal stage, and the clothes drying program ends. Through the present invention, the state of the clothes in the drying tub can be determined and different drying processes can be adopted according to the state of the clothes, the drying program control is more precise, the clothes are dried more uniformly, and the drying effect is better.

Description

technical field [0001] The present invention relates to the technical field of clothes dryers, in particular to a drying control method of a clothes dryer and a clothes dryer. Background technique [0002] With the continuous advancement of technology and the continuous improvement of people's living standards, heat pump dryers are more and more popular with consumers and the market due to their advantages of high drying efficiency, energy saving and environmental protection, and low dependence on ambient temperature. With the continuous maturity of consumers' consumption concept and the continuous progress of electronic technology, higher requirements are also put forward for the energy saving and environmental protection of heat pump dryers. Accurate and efficient drying control methods have become the research direction of heat pump dryer developers. . [0003] At present, there are many drying control methods for dryers on the market, but the basic principle is mainly t...

Problems solved by technology

The problem with this method is that when there are fewer clothes in the dryer barrel, the humidity sensor has less chance of contact with the clothes, and the reading is unstable. Simply relying on the humidity sensor to judge the drying condition of the clothes may easily cause the clothes to be over-dried or under-dried. Completely dry; when there are many clothes in the dryer barrel, the humidity sensor takes more frequently, but because there are many clothes, it is easy to cause uneven drying of the front and rear clothes
