Washing machine with active water injection balancing ring and control method thereof

Abstract

The invention relates to a washing machine with an active water injection balancing ring and a control method of the washing machine. The washing machine comprises an outer barrel and an inner barrel. The balancing ring is arranged at an opening of the inner barrel. The balancing ring is of a circular ring structure. A hollow cavity is formed in the balancing ring. The washing machine is further provided with a water inlet structure and a water drainage structure, wherein the water inlet structure is used for injecting water into the hollow cavity to balance the load eccentric quantity, and the water drainage structure is used for discharging water in the water inlet structure. According to the washing machine, the quantity of filler in the balancing ring can be changed, the unbalance effect caused by too little filler and excessive balance caused by too much filler are avoided, and the problem that the quantity of the filler in the balancing ring of a common washing machine can not be changed is solved. The balancing ring is hollow inside, and no filler with a fixed quantity is arranged in the balancing ring, so the weight of the balancing ring is reduced, the manufacturing processes of the balancing ring is simplified, the manufacturing cost is lowered, and the production efficiency is improved; moreover, energy consumption is lowered, accurate control over balance is achieved, the dehydrating vibration and noise are lowered, the distribution frequency is reduced, and the dehydrating time is greatly shortened.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a washing machine with an active water injection balance ring and a control method, which balances the internal load eccentricity by actively injecting water into the balance ring. Background technique [0002] Most existing washing machines use sealed balance rings, and the fillers are liquid or steel balls, steel ingots and the like, which are sealed in the cavity of the balance ring. When the washing machine dehydrates at high speed, according to the vibration point, the filler that can move in the cavity of the balance ring will slide to a position symmetrical to the load eccentricity of the washing machine, thereby reducing the overall eccentricity and vibration noise. There are differences in the eccentricity of each work distribution of the washing machine, especially when dehydrating loads with large water absorption such as cotton clothes, the balance ring of the fixed fi...

AI Technical Summary

Problems solved by technology

However, once the balance ring in the above patent is assembled with the washing machine, the quality of the internal balance has been determined, and it cannot be adjusted according to the load eccentricity of the washing machine, and the washing machine also needs to drive the balance inside the balance ring to rotate together, wasting the motor. driving energy consumption
