A safety device against leaks of liquid for a liquid-conducting household appliance comprises a valve arrangement that can be electrically switched between a closing position and an opening position, to prevent or enable, respectively, a flow of liquid from a liquid-supply source to the household appliance. The device further comprises:a first pipe (13) impermeable to liquid, for the flow of liquid,at least one hydraulic unit (12), having a duct for the liquid (30),a flow sensor in the at least one hydraulic unit (12). The first pipe (13) is connected in fluid communication with the duct (30) and extends longitudinally at least in part within a second pipe (14) that is impermeable to liquid, in such a way that defined between at least part of the first pipe (13) and of the second pipe (14) is a gap (G) having a proximal end and a distal end. The at least one hydraulic unit (12) has a respective hydraulic body (16) that defines the duct (30). The flow sensor is a non-mechanical flow sensor that includes at least two electrical detection elements (42) within the duct (30).

A hydraulic control device for liquid-conducting household appliances or systems comprises:a hydraulic unit (11), having a hydraulic body (15) defining a duct (30) for the liquid, the duct (30) having an inlet (18i) and an outlet (31), the duct (30) being at least partially defined with an electrically insulating material,an electrical valve arrangement (EV, SH) on the hydraulic body (15), which is electrically switchable between a closing position and an opening position, to prevent or enable, respectively, passage of the liquid between the inlet (180 and the outlet (31) of the duct (30),a flow sensor on the hydraulic body (15). The flow sensor is a non-mechanical flow sensor comprising at least two electrical detection elements (42), prearranged for contact with the liquid that flows in the duct (30) and carried by at least one support (41), that preferably at least partly extends within, or faces the inside of, the duct (30) and/or has two opposite major faces that are substantially parallel to a direction of a flow of the liquid.

A washing machine includes a box body, an inner tub in the box body, a device for driving the inner tub to rotate, and a water collecting device at the bottom of the inner tub. The inner tub is a water containing tub during washing/rinsing. The outer wall of the inner tub is provided with a dewatering channel communicating with the inner tub for draining water discharged from the inner tub. The water collecting device includes a water collecting cavity with an upper opening, the bottom wall of the water collecting cavity is provided with a recessed portion, and a water outlet end of the dewatering channel downwardly extends into the recessed portion. The outlet end of the dewatering channel is inserted into the recessed portion on the bottom wall of the water collecting cavity, so that water collection and drainage are facilitated.

A pressure relief assembly for providing thermal expansion protection to plumbing lines in a water distribution system for a home or business having a clothes washing machine wherein the water supply valve or valves and the drain connection for the washing machine are provided in a washing machine box mounted in a wall cavity, the assembly comprising a water pressure relief valve connected within the washing machine box to a washer supply line before the washer supply valve with the drain line from the pressure relief valve extending to the drain opening in the washing machine box. Optionally, the washer water supply valve is also in fluid communication with a water hammer arrestor within the washing machine box.

A pump motor is disclosed. The pump motor includes a case; a socket part disposed in a portion of the case and provided with a terminal part thereinside; and a cover part detachably coupled to the case and configured to open and close the socket part, wherein the socket part includes a moisture blocking member configured to block a gap between the case and the cover part.
