1. A diverter valve, comprising a diverter valve assembly, a diverter valve transmission assembly, a drive motor and a control device used to control the drive motor, wherein
the drive motor drives the diverter valve transmission assembly to perform a transmission action under control of the control device, so as to drive the diverter valve assembly to perform switching actions, the diverter valve transmission assembly is an intermittent gear transmission assembly, and each time the intermittent gear transmission assembly performs, driven by the drive motor, the transmission action at least once, the control device controls the drive motor to stop driving;
the intermittent gear transmission assembly comprises a drive gear and a transmission gear meshed with each other, the drive gear is connected to the drive motor, the transmission gear is connected to the diverter valve assembly, each time the drive motor performs a driving action at least once under control of the control device, the drive gear drives the transmission gear to rotate by a certain angle, and when the transmission gear rotates, the transmission gear drives the diverter valve assembly to rotate so as to perform a switching action; and
a part of an arc surface of the drive gear is provided with at least one drive tooth segment, another part of the arc surface without a drive tooth segment is provided with at least one disc-shaped projection segment, and one drive tooth segment and one disc-shaped projection segment belong to a drive group; the transmission gear is provided with a plurality of transmission tooth groups, and each transmission tooth group is matched with a corresponding drive group thereof;
each time the drive motor performs the driving action at least once, a drive tooth of a drive tooth segment on the drive gear drives a transmission tooth group on the transmission gear to rotate.
