AI Technical Summary

Technical Problem

Existing washing machines, during the spin-drying process in the non-perforated inner tub, fail to effectively address the issue of water residue in the outer tub caused by water not being drained in time, which affects spin-drying efficiency and may cause equipment vibration or damage.

Method used

A collaborative mechanism of phased rotation speed control and dynamic liquid level detection is adopted. The liquid level detection device detects the liquid level signal in the outer tank and controls the rotation timing of the inner tank to avoid water carryover caused by the water in the outer tank not being discharged in time.

Benefits of technology

It effectively improves the dehydration efficiency of washing machines with non-perforated inner drums, avoids equipment damage, and ensures the stability and safety of the dehydration process.

Abstract

The embodiment of the application discloses a dewatering control method, an electronic device and a non-porous inner drum washing machine, and belongs to the technical field of washing machines. The dewatering control method comprises the following steps: in the outer drum drainage state, sequentially executing a plurality of dewatering stages, in each dewatering stage, controlling the inner drum to accelerate to a target dewatering rotating speed; in the process of rotating the inner drum, determining whether a plurality of liquid level detection devices detect a liquid level signal; in the case that at least one liquid level detection device detects a liquid level signal, controlling the timing of stopping the rotation of the inner drum according to the liquid level signal detected by the at least one liquid level detection device; in the case that none of the plurality of liquid level detection devices detects a liquid level signal and the stage number of the current dewatering stage is less than the maximum stage number, entering the next dewatering stage. The embodiment can effectively avoid the occurrence of the "water carrying" condition of the non-porous inner drum washing machine in the high-speed dewatering process, ensure the dewatering efficiency and avoid equipment damage.
