The invention discloses a spiral water discharging pump, and relates to a water pump. The spiral water discharging pump comprises a water pump shell component, a center adjusting sealing ring component, a rotor component and a plug cock component. After washing water in a washing machine water containing bucket is emptied, if part of air in an inner cavity of a first shell barrel and a small amount of washing water are mixed to enter an inner cavity of an impeller barrel, a liquid ring is formed on the inner surface of the impeller barrel through a small amount of washing water via centrifugalforce generated through impeller rotation, part of air is wrapped in the radial inner side of the liquid ring to form an air column, the liquid ring and the air column wrapped by the liquid ring aredivided at the semi-closed impeller barrel inner cavity through blades of an impeller, and the liquid ring and the air column wrapped by the liquid ring synchronously rotate with the impeller. In theprocess that the ratio of the liquid ring volume in the inner cavity of the impeller barrel to the volume of the air column achieves the balance state, the spiral blades of the impeller cannot flap the liquid surface between the washing water and the air all the time, and vibration and noise are avoided.
Description
technical field [0001] The invention relates to a spiral drainage pump, which relates to a water pump, in particular to a drainage pump applied to a washing machine. Background technique [0002] Most of the drum washing machines use upper drainage, and the ordinary washing machine drainage pump is used in the upper drainage washing machine. When the washing machine is drained after washing and drying, after the washing water in the washing machine is emptied, the air will enter the inner cavity of the ordinary washing machine drainage pump. The impeller beats the liquid surface between the wash water and the air to generate vibration and noise. When the axis of the impeller of the drainage pump is installed and used parallel to the horizontal plane, the vibration and noise generated by the impeller hitting the liquid surface between the washing water and the air are particularly strong. Most of the ordinary washing machine drain pumps used in drum washing machines are inte...
