Description

A washing machine and control method

Technical field

The invention relates to a washing machine, in particular to a washing machine and a control method.

Background technique

With the advancement of technology, washing machines, as a commonly used household appliance, have gradually evolved from traditional pulsator or drum washing machines into multi-functional washing machines. These multi-functional washing machines include washing and drying machines, water cycle washing machines, air pressure washing machines, Steam washing machine, etc. Among them, the principle of the pulsator type washing and drying machine is that the air driven by the fan is heated by the heating device and then blown into the inner barrel. There are two main ways of blowing in, namely blowing from the upper part of the inner barrel and blowing from the bottom of the outer barrel. Due to the effect of gravity, the clothes in the pulsator washing machine naturally pile downwards. The air intake blown from the upper part of the inner barrel increases the stacking pressure of the clothes, resulting in poor stretchability of the clothes. With the air intake method of blowing in from the bottom of the outer barrel, the air flow is blocked by the inner barrel and cannot directly contact the clothes. It can only enter the inner barrel from the opening between the inner barrel and the outer barrel or the opening at the bottom of the inner barrel to contact the clothes. Clothes drying efficiency lower. Similarly, the principles and air intake methods of steam-type pulsator washing machines are similar to those of the above-mentioned pulsator-type washer-dryer. They also have the problems of poor stretchability and low efficiency of clothes.

The patent document with publication number CN108866911A discloses a washing machine. The washing machine includes an inner cylinder and a pulsator arranged in the inner cylinder. A steam generator is arranged below the pulsator for transporting steam into the inner cylinder. Due to the above structure, the present invention can quickly wet the surface and interior of clothes when the steam generator is working, improve the efficiency of steam soaking into clothes, and at the same time enable the washing machine to more quickly and thoroughly remove clothes during washing. Cleaning greatly improves the washing efficiency of the washing machine, and because the clothes are soaked in advance at the beginning of washing, the water consumption of the washing machine can be reduced to a certain extent to achieve water conservation.

The above technical solution solves the problems of poor ductility and low washing efficiency caused by the natural downward accumulation of clothes in the washing machine. However, the steam generator of the above solution is installed below the pulsator, which increases the structural complexity of the pulsator. At the same time, the steam generator It is difficult to seal, waterproof and electrically connect. Especially when the impeller rotates, a large centrifugal force is formed on the steam generator. Therefore, this structure has greater requirements on the connection strength between the steam generator and the impeller.

In view of this, the present invention is proposed.
