A washing machine and a control method therefor

Abstract

The invention provides a washing machine and a control method therefor. The washing machine comprises an inner barrel and an outer barrel. The inner barrel is only provided with water discharge holes in the upper portion of the barrel body and the other parts are sealed; the inner barrel is a water holding barrel; the outer barrel is inside provided with a heating device; a chamber between the inner barrel and the outer barrel forms a water heating space; the water heating space communicates with the inner barrel via a circulating water system; heated water is guided into the inner barrel or water in the inner barrel is heated through heat transfer of the inner barrel. The washing machine is provided with a first water quantity detection unit used for detecting the water inflow quantity of the inner barrel and a second water quantity detection unit used for detecting the water inflow quantity of the chamber between the inner barrel and the outer barrel. Water is first delivered to the chamber between the inner barrel and the outer barrel to be heated and is then guided into the inner barrel via the circulating water system, or water in the inner barrel is heated via heat transfer of the inner barrel, so that high temperature heated washing is realized, the washing efficiency and the cleaning ratio are increased and the objective of disinfection and sterilization is achieved. The structure is simple and the heating efficiency is high.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a washing machine whose inner tub is a water tub and a control method thereof. Background technique [0002] The pulsator fully automatic washing machine currently on the market has water leakage holes at the bottom and side walls of the inner tub. During the washing process, the dirt washed from the clothes will enter between the inner and outer tubs through the water leakage holes in the inner tub. After a long time, the dirt will disappear. It will be deposited on the side wall of the inner tub, the dirt deposition will become more and more serious, and it will produce peculiar smell and easily breed bacteria, which will affect the washing quality of the clothes, thus affecting people's health. Nowadays, self-cleaning and sterilization devices of washing machines generally use air-drying and nanotechnology. [0003] The Chinese Patent Application No. 200820062676.3 discloses a...

AI Technical Summary

Problems solved by technology

[0006] Although the above-mentioned non-porous inner-tub washing machine can be heated and washed, because it is heated during the water inlet process, the structure cannot be heated to the high temperature required for sterilization and disinfection, and each heating and washing requires more time.
