  • the present invention also relates to a drying machine that implements the method.
  • outdoor textiles have a waterproof and breathable thin film material with a micro-porous structure.
  • all seams and pinholes on the textiles are sealed with sealing strips, so as to ensure absolute waterproofing and block all liquids.
  • drying machines on the market do not provide a special drying procedure for outdoor textiles.
  • the outdoor textiles can only be taken out and hung at a shade place for drying.
  • a washing and drying procedure or a single drying procedure provided by a washing and drying machine in the prior art is not applicable to drying outdoor textiles. The reasons are described as follows.
  • drying modes provided by the washing and drying machines on the market are divided into two types: time drying and automatic drying. If a user selects a time drying procedure to dry the outdoor textiles, it requires that the user select appropriate drying time according to a material type, weight and nominal water content after washing of the textiles in combination with the information such as a temperature and humidity of a current environment. For an ordinary user, it is difficult to do so.
  • the automatic drying procedure in the prior art is not applicable to drying the material of outdoor textiles. Therefore, the drying procedure in the prior art has two results: if the drying time is too long, the outdoor textiles are over-dried, wrinkles easily occur to a surface of the textiles, and the fabric and sealing strips are damaged; if the drying time is too short, the nominal water content of the outdoor textiles is too high, which fails to achieve the objective of drying.
  • the present invention is directed to a method for controlling a drying machine applicable to drying outdoor textiles.

  • a drying temperature of the outdoor textiles drying procedure is lower than a drying temperature of the main drying stage of the ordinary drying procedure, and after completing the cooling stage of the outdoor textiles drying procedure, nominal water content of the outdoor textiles is higher than nominal water content of the other textiles after completing the cooling stage of the ordinary drying procedure.
  • the drying temperature of the outdoor textiles drying procedure refers to a first temperature of drying air after being heated by a heating device
  • the drying temperature of the ordinary drying procedure refers to a second temperature of drying air after being heated by the heating device.
  • the drying temperature of the outdoor textiles drying procedure is controlled between 50°C and 60°C.
  • the drying temperature of the outdoor textiles drying procedure is lower than a working temperature of the ordinary drying procedure.
  • the drying temperature of the outdoor textiles drying procedure is controlled between 50°C and 60°C.

And percentage values from 0% of nominal water content are calculated as relations between mass of water content and dry weight of the textiles.
  • the nominal water content of the outdoor textiles is within a range of 8% ⁇ 5%.
  • the drying temperature of the main drying stage of the ordinary drying procedure is between 60°C and 100°C.
  • the nominal water content of the other textiles after completing the cooling stage of the ordinary drying procedure is between -3% and 3%.

  • a controlling device is introduced to implement the ordinary drying procedure and the outdoor textiles drying procedure.
  • a technical effect of the present invention lies in that, by setting an appropriate drying working temperature, damages on the material and sealing strips at seams of the outdoor textiles during the drying procedure are prevented to the greatest extent.
  • heat of low-temperature drying is better for redistribution of the durable water repellent polymer on a fabric surface than natural drying, and protects waterproofing of the fabric surface.
  • nominal water content of a dried object is higher than nominal water content after the ordinary drying procedure is performed, which ensures that wrinkles caused by over-drying do not occur to the dried object, and at the same time, the material and sealing strips at the seams of the outdoor textiles are prevented from being damaged.

Abstract

La présente invention se rapporte à un procédé destiné à commander une machine à sécher, qui comprend la sélection et le démarrage d'une procédure de séchage de textile d'extérieur, puis à entamer une étape de préchauffage, une étape de séchage principal et une étape de refroidissement. A l'étape de séchage principal, une température de fonctionnement de la machine à sécher (1) est inférieure à une température de fonctionnement d'une procédure de séchage ordinaire, et après l'étape de refroidissement, une teneur en eau nominale de textile d'extérieur chargé (4) est supérieure à la teneur en eau nominale après la réalisation de la procédure de séchage ordinaire. Grâce au réglage d'une température de fonctionnement de séchage appropriée, on évite d'endommager, dans une très large mesure, les bandes de matière et d'étanchéité au niveau des coutures du textile d'extérieur (4) au cours de la procédure de séchage. De plus, à la fin de la procédure de séchage, la teneur en eau nominale du textile d'extérieur est supérieure à la teneur en eau nominale des autres textiles après la réalisation de la procédure de séchage ordinaire, ce qui garantit la non-apparition de plis dus au surséchage sur le textile d'extérieur (4), et on évite, en même temps, d'endommager les bandes de matière et d'étanchéité au niveau des coutures du textile d'extérieur (4). L'invention se rapporte également à une machine à sécher mettant en œuvre le procédé.
