Washing machine with water filling port type balancing ring and control method thereof

Abstract

The invention relates to a washing machine with a water filling port type 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 a clothes charging port of the inner barrel. The balancing ring is of a circular ring structure. The inner circumference of the balancing ring is provided with water filling ports, and the water filling ports are used for supplying water into the balancing ring as balancing liquid to balance the load eccentric quantity. The outer circumference of the balancing ring is provided with at least one water drainage port which can be opened or closed. According to the washing machine, 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 greatly, sealing does not need to be considered, the manufacturing processes of the balancing ring are simplified, the manufacturing cost is reduced, and the production efficiency is improved; the washing machine with the water filling port type balancing ring does not need to drive the filler in the balancing ring to rotate together, so energy consumption is lowered, an appropriate amount of water can be injected according to the measured load eccentric quantity, 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.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a washing machine with a water injection port balance ring and a control method, which can inject water into the balance to balance the load eccentricity. 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 filler cannot completely bal...

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
