The method comprises: when it is detected that a switched reluctance electric motor starts a target rotation speed, starting timing, and acquiring a first timing time; when the first timing time is greater than a commutation time corresponding to the target rotation speed and a commutation signal is detected, determining a commutation position of the switched reluctance electric motor according to the commutation signal; turning on a corresponding target phase according to the commutation position, restarting timing, and acquiring a second timing time; and when the second timing time reaches a set time, turning off a first lower-bridge switch corresponding to the phase before commutation, so as to complete the commutation of the electric motor under low-speed operation. The turn-off time of a lower-bridge switch of an original phase is delayed during a commutation process, that is, the turn-on time of the original phase is prolonged, such that a current change tends to smooth, thereby reducing the commutation noise caused by current mutation during low-speed commutation of an electric motor, without causing the torque of the electric motor to be insufficient.

Abstract

Disclosed is a raw water and waste water separating water tank, comprising: a tank structure, an initial chamber, at least one conversion chamber and a raw water chamber. A spacer member which seals and abuts against the side wall of the initial chamber so as to divide the internal space of the initial chamber into a raw water initial cavity and a waste water initial cavity is disposed at the inner part of the initial chamber; an overflow port is arranged near the upper port of the initial chamber and is used for enabling raw water in the raw water initial cavity to overflow into the conversion chamber, or enabling waste water in the waste water initial cavity into the conversion chamber after the raw water in the conversion chamber has been filtered. According to the present invention, the raw water and waste water separating water tank may reciprocally convert the raw water initial cavity and the waste water initial cavity by means of the movement of the spacer member. The arrangement of the conversion chamber enables the use of the space for containing raw water to be used for containing waste water after the raw water is filtered, and the volume of the raw water that may be added for a single time is increased under circumstances in which the total volume of the water tank has not changed. Also disclosed is a water purifier comprising the raw water and waste water separating water tank.
