1. A device (1) for water purification, the device (1) comprising a rigid dirt water container (2) for accumulating dirt water and a purification unit (5) for purifying the dirt water, wherein the dirt water container (2) is arranged above the purification unit (5) for driving water through the purification unit (5) by gravity;
wherein the purification unit (5) comprises a filter housing (5′) enclosing a purification medium that is separating an upstream side of the purification unit (5) from a downstream side of the purification unit (5) such that water in the purification unit (5) can flow from the upstream side to the downstream side only through the purification medium; wherein the purification unit (5) is a filtration unit (5) and the purification medium is a microporous filtration membrane; wherein the dirt water container (2) has a container outlet (10), and the filter housing (5′) has an upstream inlet (19) connected to the upstream side, wherein the container outlet (10) and the upstream inlet (19) are fluid-flow-connected by a first flow connector (9) for receiving dirt water from the dirt water container (2) into the upstream side of the purification unit (5); wherein the device comprises a rigid clean water tank (3) fluid-flow connected to the downstream side through a downstream outlet (29A) for receiving purified water from the downstream side; wherein the dirt water container (2) is arranged above the clean water tank (3) by a rigid connection supporting the dirt water container above the clean water tank and with a clearance of at least 5 cm between the clean water tank (3) and the dirt water container (2), wherein, the rigid connection (36, 36′) comprises a rotationally hinged (42) profile (47) for varying the distance between the clean water tank (3) and the dirt water container (2), wherein the rotationally hinged (42) profile (47) is provided with an angle varying relatively to the clean water tank (3) in dependency of the distance between the clean water tank (3) and the dirt water container (2), wherein the profile (47) is hinged in a first hinge (43, 44) at the clean water tank (3) and is hinged in a second hinge (42) at the dirt water container (2), wherein the dirt water container (2) has an upper opening having a dimension larger than a cross section of the clean water tank (3) for collapsibly receiving the clean water tank (3) inside the dirt water container (2) in storage, wherein the rigid connection (36, 36′) has a first state where the dirt water container (2) and the clean water tank (3) are in a closed position, which is a storage or transport state in which the dirt water container partly encloses the clean water tank, and the connection (36, 36′) has a second state where the clean water tank (3) and the dirt water container (2) are in a remote operational condition for water filtration, and wherein the distance between the clean water tank and the dirt water container in the second state is between 5 cm and 100 cm larger than in the closed position. |
