Abstract: A water reservoir for a drinks machine has a housing having a base and a side wall forming a water chamber. An outlet structure is formed on the base with an inner wall upstanding from the base, wherein an inner volume of the inner wall leads to an outlet of the water reservoir. An outer wall structure extends around the inner wall and a space between the inner wall and the outer wall structure forms a connection interface for connecting a water treatment unit. A lowest region of the inner wall defines the lowest liquid level in the reservoir. When the liquid is at the lowest liquid level, the water surface extends uninterrupted between the outside of the inner wall and the inside of the side wall.

Abstract: A baby bottle device (100) is provided which comprises a container (110) with a container volume (115), a teat (120) with a teat volume (125) and a valve unit (200). The teat comprises a first valve (112) for inletting air into the inside volume of the bottle (100). The inside volume of the bottle corresponds to the volume of the container (110) and the teat volume (125).

Abstract: Provided is a wet cleaning apparatus (10), such as a wet vacuum cleaner. The wet cleaning apparatus comprises a dirt inlet (11), and a motor (14) and fan (16) for delivering suction to the dirt inlet. A separator unit (18) separates water from a flow of air generated by the suction. The apparatus further includes a container (19) for collecting the separated water. The container has a top (19A) and a bottom (19B). An air passage (22) is provided in the container for passing the air separated from the water towards the motor and fan. The air passage is spatially separated from the bottom of the container. An internal wall (19E) extends from the top towards the bottom of the container. A space (25) is thus defined between the container and the internal wall. Water collected at the bottom of container is receivable in the space when the container is orientated, e.g. tilted, such that the collected water moves from the bottom towards the top of the container.

Abstract: A wet cleaning apparatus includes a cleaner head having a dirt inlet. A motor and fan deliver suction to the dirt inlet. Further, the wet cleaning apparatus includes a separator unit for separating water from a flow of air generated by the suction. The separated water is collected in a container having a top and a bottom, and a side portion extending there between. The separated air is passed out of the container towards the motor and fan via an air passage. The air passage is spatially separated from the bottom of the container. The water collected in the container sloshes against the side portion of the container when a user is pushing the cleaner head and the container forward. A water directing member sealingly adjoins the side portion, and protrudes into the container backwards from the side portion, thereby to inhibit the water sloshing against the side portion.

Abstract: A cyclone unit is for separating liquid and particles from a suction flow. A main flow inlet to the outer housing of the cyclone unit includes an opening. The transition between the main flow inlet and the outer housing at this opening has, at least for a portion of the opening, a radius of curvature of at least 0.5 mm. The large radius of curvature prevents the formation of static water drops.

Abstract: A wet vacuum cleaner uses a cyclone unit for separating liquid and particles from a suction flow. A main flow inlet to a cyclone chamber is spaced internally from its respective end by a separation distance. The separation distance is at least 0.1 times (effective/equivalent) diameter of the main flow inlet, which assists in preventing formation of large droplets which follows a path to a main flow outlet.
