A method for adjusting the amount of condensing medium according to the temperature change of the outlet air of the clothes dryer

Abstract

The invention discloses a method for adjusting the amount of condensing medium according to the temperature change of the outlet air of a clothes dryer, comprising the following steps: S1, starting to dry clothes, detecting the temperature of the air outlet of the dryer, and determining that the temperature of the outlet air reaches a set temperature value; S2, calculate the time value from the beginning of drying clothes to the temperature of the outlet air reaching the set temperature value; S3, at least determine the supply rhythm of the condensing medium according to the time value calculated in step S2; S4, use the time value determined in step S3 The supply rhythm of the condensing medium supplies the condensing medium. The supply of the condensing medium is shut off during the process of starting the dryer until the temperature of the outlet air of the dryer reaches the set temperature value. The larger the time value, the more moisture in the fabric, and the longer the subsequent supply of condensation medium. The method of the invention can adjust the supply amount of the condensing medium per unit time according to the change of the temperature of the outlet air, so that the drying efficiency can be ensured and the waste of the condensing medium can be avoided at the same time.

Description

technical field [0001] The invention belongs to the technical field of clothes dryers, and in particular relates to a method for adjusting the amount of condensing medium according to changes in the temperature of the outlet air of the clothes dryer. Background technique [0002] Clothes dryers generally have a drum containing fabrics to be dried and a condensing device communicating with the drum space. The heated process air meets the wet fabric in the cylinder, evaporates the moisture in the fabric and becomes moist. The hot, humid process air then enters the condensing unit. In a condensing unit, the process air exchanges heat with a cooler condensing medium, and the moisture in it is condensed and separated from the process air. During the whole drying process of the clothes dryer, the moisture content of the air near the condensing device changes, so the power required by the clothes dryer for the condensing device is also different during the whole working process. ...

AI Technical Summary

Problems solved by technology

This patent focuses on a method of adjusting the supply rhythm of the condensing medium according to the temperature of the condensing medium. The problems with this method are: 1. The temperature change of the condensing medium is caused by the heat dissipation of the air out of the dryer. The temperature change of the medium to reflect the drying process is not direct; 2. The specific heat capacity of the condensing medium, especially when water is used as the condensing medium, is relatively large. Therefore, the temperature response of the condensing medium is not sensitive enough, which further affects the adjustment of the entire condensing medium supply. precision

However, this method does not consider the influence of fabric humidity, and the single reduction of water supply will make the condensation insufficient, the drying time will be longer, and the energy consumption will be greater.
