Clothes treating apparatus

A clothes treating apparatus comprising:

• a drum configured to receive laundry;
• a tub that accommodates the drum;
• a main body that accommodates the tub;
• a detergent drawer configured to be withdrawn from and inserted into the main body;
• a spray nozzle configured to spray washing water to the detergent drawer;
• a water-collecting container formed in a bottom portion of the tub and configured to receive the washing water;
• a washing line configured to supply the washing water from the water-collecting container to the spray nozzle;
• a circulation line configured to supply the washing water from the water-collecting container to the drum;
• and
• a flow-path conversion pump configured to receive the washing water from the water-collecting container and to supply the washing water selectively to the washing line or the circulation line,
• wherein the flow-path conversion pump comprises:
• an impeller,
• a motor connected to the impeller and configured to transmit power to the impeller,
• an impeller housing that accommodates the impeller and is configured to receive the washing water from the water-collecting container, the impeller housing defining a first housing outlet and a second housing outlet that extend parallel to a tangential direction of rotation of the impeller,
• a flow-path switch that defines an internal space, the flow-path switch comprising (i) a first inlet configured to communicate with the first housing outlet, (ii) a second inlet configured to communicate with the second housing outlet, (iii) a first outlet configured to communicate with the first inlet and connected to the washing line, and (iv) a second outlet configured to communicate with the second inlet and connected to the circulation line, and
• a diaphragm that is disposed in the internal space of the flow-path switch, that separates the first inlet and the second inlet from each other, and that separates the first outlet and the second outlet from each other,
• wherein the diaphragm is made of an elastic material, has a shape in which a central portion of a circular plate protrudes to have a curvature, and is pre-formed to maintain the protruding shape of the central portion,
• wherein a protruding direction of the central portion of the diaphragm is configured to be changed by 180 degrees (°) based on an external force, and the changed protruding direction of the central portion of the diaphragm is configured to be maintained based on the external force being eliminated, and
• wherein the diaphragm is configured to respectively open and close flow paths of the washing water in the flow-path switch based on the protruding direction of the diaphragm being changed.
