Problems solved by technology

[0008] In the existing automatic drying clothes dryers, due to the influence of different weights, types and initial moisture content of the clothes loaded, the remaining time displayed often does not coincide with the time required for actual operation
The use of users is greatly restricted, because they do not know the remaining time of drying clothes, so they cannot arrange the time reasonably

Embodiment 1

[0068] According to the humidity time curve, the remaining time display calculation example:

[0069] Set the initial drying time as the drying time of clothes with rated capacity, which is the default drying time. For example, the default drying time for 8kg clothes is 2 hours and 30 minutes. The countdown counts down during the drying operation, and the time runs to the set countdown When the remaining time is 5 minutes, if the humidity value is still greater than the set humidity threshold h1 is 1750, then the time is adjusted to the preset first remaining time of 1 hour. If the time runs to the cold air cooling stage, the detected humidity value reaches the set value When the humidity threshold is 1750, that is, it is less than or equal to the set humidity threshold and greater than the set drying target humidity h2 is 330, then it is adjusted to the preset remaining time corresponding to the currently displayed remaining time according to the current remaining time. The ad...

Embodiment 2

[0075] In this embodiment, on the basis of Embodiment 1, that is, on the basis of the preliminary adjustments 1) 2) 3) in Embodiment 1, the countdown runs to 5 minutes before the set countdown remaining time, and if the end condition is reached, the humidity value is detected When the set drying target humidity value h2 is reached to 330, directly adjust to the remaining cooling time of the cold air. If the end condition is not met, the remaining time is accurately calculated as the remaining time of the second adjustment Δt, Δt=t2-t,

[0076] The algorithm is as follows: Δt = ( hum - 330 ) ( 1750 - hum ) * Δt 1 + ( t + Δt ) λ ...

Abstract

The invention discloses a method for adjusting the remaining drying time of a clothes dryer. The clothes dryer is provided with a humidity detection device, a timing device and a time display device. The clothes dryer is provided with a default initial clothes drying time length. The clothes drying process includes a hot air clothes drying stage and a cold air temperature reduction stage, the initial clothes drying time length is reduced gradually in a countdown mode during drying, the humidity detection device detects the humidify value of a load in the hot air clothes drying stage, and when the detected humidity value reaches a set humidity threshold value, the current remaining time is adjusted to be a preset remaining time length corresponding to the remaining time displayed currently. According to the method, remaining drying time is adjusted by comparing the detected humidity value of the load with the preset humidity value, the judgment method is simple, and calculation is accurate.

Description

technical field [0001] The invention relates to the field of clothes drying, in particular to a method for adjusting the remaining drying time of a clothes dryer. Background technique [0002] In general, a laundry device such as a clothes dryer is a household appliance for automatically drying wet laundry after washing. Clothes dryers dry clothes by directly or indirectly heating the clothes inside the drum to evaporate moisture and drain the water out of the drum. [0003] The drying method of directly heating the clothes may cause serious deformation of the clothes. As a result, the common drying method for drying is to increase the temperature inside the cylinder or heat the gas through a heater to generate hot air and draw the hot air into the cylinder to dry the clothes. [0004] In the clothes dryer that dries clothes by using hot air, external air is forced into the drum by a fan, heated by a heater installed outside the drum, and the heated hot air is discharged i...
