Title: SWING RANGE CONTROL ASSEMBLY, HOUSEHOLD APPLIANCE, AND SWING CONTROL METHOD AND DEVICE
Abstract:
Disclosed are a swing range control assembly, a household appliance, and a swing control method and device. The assembly comprises: a V-type grooved gear (110), a pressure pump, a roller (120) with a pre-set groove, and a transmission belt (130). The V-type grooved gear (110) comprises a central shaft (113) and two conical plates (111, 112) sleeved thereon. The side faces of the two conical plates (111, 112) and the central shaft (113) define V-type grooves. A gear is arranged on the circumference of at least one conical plate. The gear meshes with a switch for rocking, when the switch for rocking is pressed down. The transmission belt (130) is used for surrounding the V-type grooves in the V-type grooved gear (110) and the pre-set groove in the roller (120). The two conical plates (111, 112) adjust the surrounding radius of the transmission belt (130) around the V-type groove (110) under the control of the pressure generated by the pressure pump. The roller (120) is fixed in a rocking plate, and the swing range is controlled through the rocking plate. The swing control assembly solves the problem of inapplicability of a household appliance to some scenes due to fixed swing range of the household appliance.
