(57) [Abstract] [Purpose] The strength of the water flow in the washing and rinsing process can be set in multiple stages, and the water flow intensity of these multiple stages corresponds to the load level of the laundry, that is, the level of the water level. It is set to, and a water flow with an appropriate strength suitable for the load and the quality of the laundry can be obtained. A washing machine in which a DC brushless motor 8 is used as a motor for rotating a stirring blade, and the DC brushless motor 8 is provided with an encoder for detecting a motor rotation speed and a rotation angle, the rotation speed of the DC brushless motor 8, Rotation angle, rotation speed rising speed and falling speed, The value of the stop determination time can be set arbitrarily, and the strength of the water flow is determined by selecting these set values in accordance with the load amount determination result and the water level. |
