Abstract:
A lift device for a front loading washing machine, the device comprising: a casing having a chamber structure, and centrifugal assemblies, such as a valve body guide column, a valve core, a counterbalance weight guide column, a counterbalance weight part, a balance rod, and an elastic part in the chamber structure, the middle part of the balance rod being pivotally connected to the interior of the casing, a first end of the balance rod being hinged to a first end of the counterbalance weight guide column, a second end of the counterbalance weight guide column passing through the casing in a sliding mode and then being connected to the counterbalance weight part, the elastic part being arranged between the counterbalance weight guide column and the casing and used for restoring the position of the counterbalance weight part, a second end of the balance rod being hinged to a first end of the valve body guide column, and a second end of the valve body guide column being connected to the valve body after passing through the casing. The problem of a shortened service life because of unreasonable arrangement of centrifugal assemblies of an existing lift device for a front loading washing machine is solved, and the centrifugal assemblies and a lever structure are arranged more reasonably.
