Description:FIELD OF THE INVENTION
[1] The present disclosure generally relates to rotary pumps. More particularly, the present disclosure relates to a rotary pump having a dual functionality of drainage and recirculation of water, used for a washing machine.
BACKGROUND
[2] Washing machines are essential appliances for many households around the world. Washing machines are designed to clean and wash different types of laundry, including clothes, bed sheets, curtains, towels, and the like. The primary use of a washing machine is to clean clothes, thereby saving time and energy compared to manual washing. Modern washing machines are relatively energy efficient and consume less water and electricity compared to traditional washing methods. Washing machines operate with different wash cycles, allowing users to choose the appropriate cycle depending on the type of fabric and level of dirt.
[3] Typically, some of the main components in a washing machine include a drum/tub, a water pump, a drain pipe, a water inlet valve, an ag , Claims:WE CLAIM:

1. A rotary pump (10) for a washing machine (02), the rotary pump comprising (10):
a casing (12);
a water inlet pipe (14) coupled to the casing (12);
a water drain pipe (16) disposed proximate to an outlet cavity (20) in the casing (12) and coupled to the casing (12);
a water recirculation pipe (18) disposed proximate to the outlet cavity (20) and coupled to the casing (12), wherein the water drain pipe (16), the water recirculation pipe (18), and a portion (26) of the outlet cavity (20) proximate to the water drain pipe (16) and the water recirculation pipe (18), form a substantially U-shaped channel;
an impeller (19) disposed within the casing (12);
a motor (21) coupled to the impeller (19) and configured to drive the impeller (19); and
a flow regulator structure (36) having a substantially c-shaped configuration, disposed at a bottom side (24) of the outlet cavity (20) of the casing (12), wherein each of first and second end portions (52, 54) of the flow regulator structure (36) is incline
