[0002] Washing machine is a kind of widely used household appliance. The washing machine generally includes a body with a washing tub inside. The washing machine is generally equipped with a detergent dispenser for adding detergent to the washing tub. At present, the double-chamber gear pump is the A device that is commonly used in automatic dispensers can satisfy the separate injection of two detergents at the same time. The rotation of the gear is converted into the expansion and contraction of the detergent extrusion. Usually, the crank slider mechanism is used. Because the crank slider The stability of the detergent extrusion is poor (the connecting rod is always in a swinging state), the force direction of the detergent extrusion is uneven, and the service life and performance of the detergent extrusion are not guaranteed. In addition, the double-chamber gear pump relies on The ratchet structure realizes single motor dual control, complex structure, many components, and high cost

Abstract

The invention relates to the field of washing machines, in particular to a detergent dispenser. It includes a motor and two delivery pumps. The delivery pump is provided with a liquid inlet and a liquid outlet. The delivery pump includes a cavity and a push rod slidingly arranged in the cavity. The motor drives the push rod to slide through the drive device. The push rod is used for Push the detergent entering from the liquid inlet to the liquid outlet. The driving device includes a reversing wheel driven by a motor. There are two protruding elastic paddles on the reversing wheel. Extend, the elastic paddles correspond to the push rods one by one, one end of the push rod is set on the casing of the delivery pump through the elastic piece, when the motor rotates forward, one of the elastic paddles lifts up the corresponding push rod, when the motor reverses , and the other elastic paddle jacks up the other corresponding push rod. The invention improves the structure of the double-cavity gear pump, improves the stress of the detergent extruded part, ensures its performance, simplifies the structure of the double-cavity gear pump, and saves costs.
