The invention relates to a strong discharge pump structure and a washing machine with the strong discharge pump structure, including a body, a volute, a drain pipe, an impeller, a driving part and a pressure component. The present invention directly associates the volute with a pressure switch, When in use, after water enters the volute from the first water inlet and the second water inlet, even though the volute and the pressure components together form a relatively independent pressure balance area, as the water level in the volute rises, the pressure in the pressure balance area increases. Large, when the starting pressure of the pressure switch is reached, the driving part starts to drive the impeller to drain water. When the water discharge is nearly completed, the internal pressure is higher due to the rotation of the impeller in the volute, until the water is completely drained, the impeller runs idly, and the pressure drops When the stop pressure of the pressure switch is reached, the driving member drives the impeller to stop working. The present invention improves the pressure sensing accuracy by balancing the set pressure in the volute and the pressure switch, reduces the residual water in the pump, and is beneficial to improve the service life of the pump.
