Title: WATER SEAL CLUTCH AND WASHING MACHINE THEREFOR
Abstract:
A water seal clutch and a washing machine therefor. The clutch is provided with a mechanical sealing device, and has the function of communicating a washing barrel (18) with an external cylinder (19) so that the water in the washing barrel (18) is directly connected to an air chamber cavity (13) of a water level sensor on an exterior of the external cylinder (19), and a drainage valve (15). There is no water between the external cylinder (19) and the washing barrel (18). A connection disc (25) is mounted on an upper shaft sleeve (2) of the clutch, and is provided with several water-passing holes (4). A connection ring (26) is fixed on the connection disc (25). A cavity shell consisting of a cavity upper cover (8) and a cavity lower cover (11) is inserted into a large water seal (9) tank of the clutch, and is fixed with a bottom plate of a mounting plate (24) of the clutch. An upper water seal (7) having an inside diameter matching the connection ring (26) is fixed on the cavity upper cover (8). The clutch is directly mounted on the bottom of the external cylinder (19) of the washing machine to pass through a central hole at the bottom of the external cylinder (19) to sealably match the external cylinder (19) by means of a sealing pad (10) at an outer edge of the cavity upper cover (8). A washing barrel flange (21) matches the connection disc (25) on the clutch. An O-shaped sealing ring (6) is provided between the washing barrel flange (21) and the connection disc (25) to achieve the sealing effect.
