A port arrangement, a purified water producing apparatus comprising the port arrangement and a method for performing port cleaning of a purified water producing apparatus

A port arrangement comprising:

• a fluid module including:
• a first port arranged to receive a first connector, wherein the first port includes a first tube and a first interior wall concentric with the first tube, the first interior wall providing a first circumferential space around the first tube, and wherein the first port further includes a first seat extending from the first interior wall to form a front end of the first port;
• a second port arranged to receive a second connector, wherein the second port includes a second tube and a second interior wall concentric with the second tube, the second interior wall providing a second circumferential space around the second tube, and wherein the second port further includes a second seat extending from the second interior wall to form a front end of the second port;
• a bypass channel connecting the first circumferential space and the second circumferential space;
• and
• a door including a first seal and a second seal positioned to an inner wall of the door such that in a closed position the first seal abuts against the first seat and the second seal abuts against the second seat to thereby seal the first circumferential space and the second circumferential space, wherein the door is arranged to be positioned in the closed position against the fluid module.

A purified water producing apparatus comprising:

• a casing;
• a fluid circuit enclosed inside the casing, wherein the fluid circuit is arranged to produce a flow of purified water from a source of water and to transport used fluid to a drain;
• and
• a port arrangement including a first port, a second port, and a door, wherein the port arrangement is positioned with respect to the casing such that the door, a front end of the first port and a front end of the second port are each accessible from outside of the purified water producing apparatus such that the first port is arranged to receive a first connector and the second port is arranged to receive a second connector, wherein the first port is fluidly connected to the fluid circuit at a back end of the first port, and wherein the second port is fluidly connected to the fluid circuit at a back end of the second port.

A method for performing port cleaning of a water producing apparatus having a casing, a fluid circuit enclosed inside the casing, and a port arrangement, the fluid circuit being arranged to produce a flow of purified water from a source of water and to transport used fluid to a drain, and wherein the port arrangement includes a first port, a second port, and a door, wherein the port arrangement is positioned with respect to the casing such that the door, a front end of the first port and a front end of the second port are each accessible from outside of the purified water producing apparatus such that the first port is arranged to receive a first connector and the second port is arranged to receive a second connector, wherein the first port is fluidly connected to the fluid circuit at a back end of the first port, and wherein the second port is fluidly connected to the fluid circuit at a back end of the second port, the method comprising:

• producing a cleaning fluid with the fluid circuit;
• passing the cleaning fluid through the first port via a first tube of the first port to a first circumferential space, from the first circumferential space via a bypass channel to a second circumferential space, and thereafter to a second tube of the second port;
• and
• passing the cleaning fluid from the second tube to the drain.

A non-transitory, computer-readable medium storing instructions that, when executed by a processor of a water producing apparatus, cause the processor to perform a set of operations, the water producing apparatus including a casing, a fluid circuit enclosed inside the casing, and a port arrangement, the fluid circuit being arranged to produce a flow of purified water from a source of water and to transport used fluid to a drain, and wherein the port arrangement includes a first port, a second port, and a door, wherein the port arrangement is positioned with respect to the casing such that the door, a front end of the first port and a front end of the second port are each accessible from outside of the purified water producing apparatus such that the first port is arranged to receive a first connector and the second port is arranged to receive a second connector, wherein the first port is fluidly connected to the fluid circuit at a back end of the first port, and wherein the second port is fluidly connected to the fluid circuit at a back end of the second port, the set of operations comprising:

• producing a cleaning fluid with the fluid circuit;
• passing the cleaning fluid through the first port via a first tube of the first port to a first circumferential space, from the first circumferential space via a bypass channel to a second circumferential space, and thereafter to a second tube of the second port;
• and
• passing the cleaning fluid from the second tube to the drain.
