Abstract

A method for performing port cleaning of an apparatus having a casing, a fluid circuit enclosed inside the casing, and a port arrangement. The method includes producing a cleaning fluid with the fluid circuit; passing the cleaning fluid through a 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 a second port; and passing the cleaning fluid from the second tube to a drain.

Claims (31)

1. A method for performing port cleaning of an 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 transport used fluid to a drain,

wherein the port arrangement includes a first port, a second port, and a door, the port arrangement being 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 apparatus such that the first port is arranged to receive a first connector and the second port is arranged to receive a second connector, and

wherein a back end of the first port is fluidly connected to the fluid circuit and a back end of the second port is fluidly connected to the fluid circuit, 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.

2. The method according to claim 1 , further comprising passing the cleaning fluid during a certain time period meeting a cleaning criterion for the first port and the second port.

3. The method according to claim 1 , further comprising receiving a signal indicating that the door is closed prior to passing the cleaning fluid through the first port.

4. The method according to claim 1 , wherein a heated cleaning fluid is produced.

5. The method according to claim 1 , wherein the bypass channel connects to the first circumferential space at an inner bottom of the first circumferential space, and the bypass channel connects to the second circumferential space at an inner bottom of the second circumferential space.

6. The method according to claim 5 , wherein the bypass channel includes a main bore, wherein the main bore connects the first circumferential space and the second circumferential space.

7. 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, the port arrangement being 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 a back end of the first port is fluidly connected to the fluid circuit and a back end of the second port is fluidly connected to the fluid circuit.

8. The purified water producing apparatus according to claim 7 , further comprising a control unit configured to:

receive a door position signal indicating a position of the door, and

control a flow of cleaning fluid to the port arrangement based on the position of the door.

9. The purified water producing apparatus according to claim 8 , wherein the control unit is configured to direct the flow of cleaning fluid to the back end of the first port upon the door position signal indicating that the door is in a closed position, whereby the cleaning fluid enters a first tube and flows into a first space of the first port, thereafter via a bypass channel to a second space and into a second tube, thereafter leaving the second port via the back end of the second port, and thereafter the cleaning fluid is further transported to the drain via the fluid circuit.

10. The purified water producing apparatus according to claim 9 , wherein the second tube includes a threaded outer side.

11. The purified water producing apparatus according to claim 8 , wherein the fluid circuit includes a heating device arranged to heat the cleaning fluid to a temperature meeting a cleaning criterion for the first port and the second port.

12. The purified water producing apparatus according to claim 7 , wherein the first port and the second port are designed as Luer type conical fittings.

13. The purified water producing apparatus according to claim 7 , further comprising a sensor arrangement configured to detect whether the door is in a closed position, and to generate a door position signal indicating a position of the door.

14. The purified water producing apparatus according to claim 7 , further comprising a spring-loaded latch assembly configured to lock the door to the casing.

15. A non-transitory, computer-readable medium storing instructions that, when executed by a processor of an apparatus, cause the processor to perform a set of operations, the 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,

wherein the port arrangement includes a first port, a second port, and a door, the port arrangement being 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 apparatus such that the first port is arranged to receive a first connector and the second port is arranged to receive a second connector, and

wherein a back end of the first port is fluidly connected to the fluid circuit and a back end of the second port is fluidly connected to the fluid circuit, 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.
