Drying control method for water-saving washing machine to realize just-in-time (JIT) stop after drying clothes

Abstract

The invention relates to a drying control method for a water-saving washing machine to realize just-in-time (JIT) stop after drying clothes. The method comprises the following steps of: at the beginning of drying, detecting the temperature of hot steam in an internal cylinder by using an internal cylinder temperature sensor; judging whether the temperature is lower than a set first starting temperature, if so, closing a water inlet valve of a dehumidifying tube, otherwise, opening the water inlet valve of the dehumidifying tube; judging whether the temperature of the hot steam in the internal cylinder is lower than a set second starting temperature, if so, closing the water inlet valve of the dehumidifying tube, otherwise, returning to judge continuously; and judging the drying degree of the clothes in the internal cylinder, when the drying degree reaches a set value, stopping a heater, and when the temperature is lower than a set opening safety temperature, stopping a drying fan and ending up the drying process. The method has the advantages of reducing the water consumption, improving the condensing efficiency of the hot steam in the internal cylinder, automatically detecting the drying degree of the clothes, automatically stopping the drying motion after detecting the clothes are dried and fulfilling a high-efficiency, rapid and energy-saving clothes-drying aim.

Description

technical field [0001] The invention relates to the technical field of washing machines, in particular to a drying control method for a water-saving washing machine to stop immediately after drying. technical background [0002] At present, there are usually two heating and drying methods for clothes: a hot air direct discharge type and a condensation type. Among them, the direct discharge type uses hot air to directly blow through the wet clothes, and the water vapor generated is directly discharged from the body to the surroundings of the room. The condensing type uses circulating hot air to heat the clothes to generate steam, and condenses the water in the hot steam through the tap water in the condensation pipe. The liquid water generated is discharged from the drain pipe, and the whole machine is directly discharged without water vapor. It is an environmentally friendly drying mode, high-end Small-scale washing and drying all-in-one machines or clothes dryers mostly us...

Problems solved by technology

The disadvantages of this control technology are: the consumption of cooling water is large during the drying process, the heat exchange efficiency is low, the process control method is single, and it is impossible to distinguish whether the clothes are dry during the drying process, and the drying effect is only based on the set drying The working time is guaranteed, usually either the drying is not dry, or the drying is too much, and the process control is unreasonable
