WIPO Patent Application WO/2018/045807
Kind Code:
A1
Abstract:
A spray arm device (10) and home water appliance, the spray arm device (10) comprising a water inlet pipe (12), a spray arm (14) and a water spreading element (16). A fixed gear (122) is provided on the end of the water inlet pipe (12). The spray arm (14) can rotate about a first axis (1226) of the fixed gear (122) to be connected to the water inlet pipe (12). The spray arm (14) is provided with a spray arm cavity (142) which is in communication with the water inlet pipe (12). The spray arm (14) comprises a first sub-spray arm (144). The first sub-spray arm (144) is provided with a plurality of spray holes (1442b) which are in communication with the spray arm cavity (142). The water spreading element (16) is provided on the first sub-spray arm (144). One end of the water spreading element (16) is provided with a movable gear (162). The movable gear (162) is engaged with the fixed gear (122). The movable gear (162) comprises a second axis (1624). The water spreading element (16) comprises a plurality of water spreading blocks (164). The plurality of water spreading blocks (164) is respectively provided at positions corresponding to the plurality of first spray holes (1442b). The water spreading element (16) can revolve around the first axis (1226) and rotate about the second axis (1624) simultaneously, so as to allow the water spreading blocks (164) to adjust the direction of the water coming out from the first spray holes (1442b). The first axis (1226) is perpendicular to the second axis (1624). The spray angle of the spray arm device can be continuously changed with the revolution and rotation of the water spreading element, such that the cleaning area can be continuously changed with the change of the angle, expanding the cleaning range of the spray arm device and avoiding the occurrence of an area which cannot be cleaned.
