Description

Control method of clothes drying equipment and clothes drying equipment Technical Field The invention belongs to the technical field of clothes treatment equipment, and particularly relates to a clothes drying equipment control method and clothes drying equipment. Background Although the existing washing machine generally has a spin-drying function, the spin-dried clothes still contain partial moisture, and the clothes can be obtained only by airing the clothes. With the improvement of life quality of people, clothes drying equipment is provided because clothes can not meet wearing requirements due to long drying time, and especially, the clothes drying equipment is particularly required for the condition that the clothes are difficult to dry in winter in north and in summer in south. The equipment used to dry the laundry is required to be able to provide sufficient heat to assist in the evaporation of the moisture from the laundry. Meanwhile, the full contact between the clothes and the heat is ensured, and the drying speed of the clothes can be greatly accelerated. In addition, when drying clothes, avoid causing the damage to clothes, still need control the temperature of drying, and the clothing of different materials need have different stoving temperatures again, and the heating control precision of clothing drying equipment among the prior art is not high, still can't realize temperature regulation's function. The above information disclosed in this background section is only for enhancement of understanding of the background section of the application and therefore it may not form the prior art that is already known to those of ordinary skill in the art. Disclosure of Invention The invention provides a control method of clothes drying equipment, which aims at the technical problems that the heating control precision of the clothes drying equipment in the prior art is not high and the temperature adjustment function cannot be realized. In order to achieve the aim of the invention, the invention is realized by adopting the following technical scheme: A laundry drying appliance control method comprising: Acquiring an initial heating temperature T0; detecting an initial humidity value S0; Determining an initial wind speed according to the initial humidity value S0, controlling a fan to operate, controlling an electric heating pipe to operate according to the initial heating temperature T0, and detecting the humidity value S1 again after maintaining the operation time T1; The heating temperature is adjusted according to the humidity value S1. Further, in the step of adjusting the heating temperature according to the humidity value S1, when the humidity value S1 is greater than the first set threshold, the heating temperature is increased according to a step length of 5% -15%. Further, the method further comprises the step of detecting the temperature HT1 near the clothes, and when the temperature HT1 is larger than the first temperature limit value and smaller than the second temperature limit value, the heating temperature is reduced; when the temperature HT1 is not less than the second temperature limit value, the electric heating pipe is closed; Wherein the first temperature limit is less than the second temperature limit.
