DETAILED DESCRIPTION OF THE EMBODIMENTS

[0039] FIG. 1 is a block diagram which illustrates a first embodiment of a distributed sterilizer system 100 for distributing ozone water to a plurality of rooms R1, R2, R3 which has an ozone generation system 1, a plurality of injection devices 2a, 2b, 2c, a plurality of flow switches 3a, 3b, 3c, a plurality of water outlets 9a, 9b, 9c and a delivery piping system 8. The plurality of rooms, R1, R2, R3 are different sections in a kitchen area in which ozone water is used for washing in the washing section, butchery section and food preparation section.

[0040] The ozone generation system 1 comprises a centralized oxygen concentrator 4, three oxygen flow meters 5a, 5b, 5c, and three ozone generators 6a, 6b, 6c. The outdoor air is directed to the ozone generation system 1 in which it is first directed to the centralized oxygen concentrator 4. In the centralized oxygen concentrator 4, the supply of outdoor air containing 21% of oxygen combined with nitrogen and a mixture of other gases. The air supply is then pressurized and compressed in the centralized oxygen concentrator 4 to yield oxygen with a pressure in the range of 0.04 MPa to 0.06 MPa. The examples of the different ranges of the oxygen purity/concentration generated from the centralized oxygen concentrator 4 are as follows: 55%@3 LPM, 70%@2 LPM and 90%@1 LPM.

[0041] In this embodiment, the forming and distribution of ozone water to a plurality of rooms R1, R2, R3 is determined by a demand-based configuration. Each of the injection devices 2a, 2b, 2c is equipped with a flow switch 3a, 3b, 2c, respectively. When a user opens any of the water outlets 9a, 9b, 9c in any of the specific rooms R1, R2, R3, water starts to flow from an incoming water supply 15 to the injection devices 2a, 2b, 2c. Upon detecting the flow of water in the injection devices 2a, 2b, 2c, the flow switches 3a, 3b, 3c send signals to the system controller 7 to send signals to the ozone generation system 1. Upon receiving signals from the system controller 7, the centralized oxygen concentrator 4 in the ozone generation system 1 start supplying oxygen to the ozone generators 6a, 6b, 6c through the plurality of oxygen flow meters, 5a, 5b, 5c respectively, to generate ozone. The ozone generated from the ozone generators 6a, 6b, 6c is supplied to the injection devices 2a, 2b, 2c to initiate the mixing of the ozone with the flow of water in the injection devices 2a, 2b, 2c to form ozone water. The ozone water formed in the injection devices 2a, 2b, 2c is distributed to the rooms R1, R2, R3 in which a flow of water is detected in the respective injection devices 2a, 2b, 2c. The ozone water is distributed to the plurality of rooms R1, R2, R3 through the delivery piping system 8.

[0042] For example, when a user opens a water outlet 9a in room R1, water from the incoming water supply 15 starts to flow to the injection device 2a. Upon detecting the flow of water in the injection device 2a, the flow switch 3a sends signals to the system controller 7 to send signals to the centralized oxygen concentrator 4 to supply oxygen to the ozone generator 6a to generate ozone. The ozone generated from the ozone generator 6a is supplied to the injection device 2a to initiate the mixing of the ozone with the flow of water in the injection device 2a to form ozone water. The ozone water formed in the injection device 2a is distributed to room R1 through the delivery piping system 8.

[0043] FIG. 2 is a block diagram which illustrates a second embodiment of a distributed sterilizer system 200 which comprises all the components of the first embodiment with the addition of a dedicated ozone generator 6d in the ozone generation system 1, an oxygen flew meter 5d and a timer 12 as incorporated in the system controller 7. In this embodiment, the forming and distribution of ozone water to a plurality of rooms R1, R2, R3 is determined by a similar demand-based configuration as illustrated in FIG. 1. This embodiment accommodates the feature of generating and supplying ozone generated from the ozone generation system 1 directly to a plurality of other rooms R5, R6, R7 according to a time-based configuration using a timer 12 as incorporated in the system controller 7. In this embodiment, an ozone generator 6d in the ozone generation system 1 serves as a dedicated ozone generator for supplying ozone directly to the plurality of other rooms R5, R6, R7. The plurality of other rooms, R5, R6, R7 are different sections in a kitchen area (washing section, butchery section and food preparation section) in which ozone is used to sterilize the surrounding air in the rooms

[0044] The timer 12 selectively operates the dedicated ozone generator 6d of the ozone generation system 1 between on and off states by defining the duration of the time intervals for the OFF and ON states. According to the time interval, the dedicated ozone generator 6d generates and supplies ozone directly to the plurality of other rooms R5, R6, R7. The duration of the time intervals is configured by the user. For example, in this embodiment, the interval time is 15 minutes. The dedicated ozone generator 6d is switched OFF for an interval time of 15 minutes. After the interval 15 minutes ends, the dedicated ozone generator 6d is switched ON again for the next 15 minutes before it is switched OFF again.

[0045] During the interval time of 15 minutes in which the dedicated ozone generator 6d is switched ON, the system controller 7 sends signals to the centralized oxygen concentrator 4 in the ozone generation system 1 to supply oxygen to the dedicated ozone generator 6d through an oxygen flow meter 5d. The dedicated ozone generator 6d generates a supply of ozone to be distributed directly to the plurality of other rooms R5, R6, R7 through a series of output tubing 10 and air nozzles 11.

[0046] FIG. 3 is a block diagram which illustrates a third embodiment of a distributed sterilizer system 300 which comprises all the components of the first embodiment and an addition of a shared ozone generator 6e in the ozone generation system 1, an oxygen flow meter 5e, an injection device 2d, a flow switch 3d and a timer 12. In this embodiment, the forming and distribution of ozone water to a plurality of rooms R1, R2, R3, R4 is determined by a similar demand-based configuration as illustrated in FIG. 1. This embodiment accommodates the feature of generating and supplying ozone generated from the ozone generation system 1 directly to a plurality of other rooms R5, R6, R7 according to a time-based configuration using a timer 12 as incorporated in the system controller 7. In this embodiment, an ozone generator 6e in the ozone generation system 1 serves as a shared ozone generator for supplying ozone directly to the plurality of other rooms R5, R6, R7 and to an injection device 2d.

[0047] The timer 12 selectively operates the shared ozone generator 6e of the ozone generation system 1 between on and off states by defining the duration of the time intervals for the OFF and ON states. According to the time interval, the shared ozone generator 6e generates and supplies ozone directly to the plurality of other rooms R5, R6, R7 and to an injection device 2d. The duration of the time intervals is configured by the user. For example, in this embodiment, the interval time is 15 minutes. The shared ozone generator 6e is switched OFF for an interval time of 15 minutes. After the interval 15 minutes ends, the shared ozone generator 6e is switched ON again for the next 15 minutes before it is switched OFF again.

[0048] During the interval time of 15 minutes in which the shared ozone generator 6e is switched ON, the system controller 7 sends signals to the centralized oxygen concentrator 4 to supply oxygen to the shared ozone generator 6e through the oxygen flow meter 5e. The shared ozone generator 6e generates a supply of ozone to be distributed directly to the plurality of other rooms R5, R6, R7 and to the injection device 2d for forming ozone water to be supplied to the room R4. The supply ozone generated from the shared ozone generator 6e is supplied directly to the plurality of other rooms R5, R6, R7 through a series of output tubing 13 and air nozzles 11. The ozone distributed from the shared ozone generator 6e to the injection device 2d remains available in the injection device 2d for the process of mixing subjected to a demand by the user in room R4. When a user opens the water outlet 9d in the room R4, water starts to flow from the incoming water supply 15 into the injection device 2d. The available supply of the ozone generated from the shared ozone generator 6e is mixed with the flow of water in the injection device 2d to form ozone water. In the event that the water outlet 9d is closed in the room R4, and no water flows into the injection device 2d, the unused ozone remaining in the injection device 2d generated from the shared ozone generator 6e is channeled to the plurality of other rooms R5, R6, R7 through an output tubing 13.

[0049] In this third embodiment, the forming and distribution of ozone water to a plurality of rooms R1, R2, R3, R4 is determined by a similar demand-based configuration as illustrated in FIG. 1. When a user opens any of the water outlet 9a, 9b, 9c, 9d in any of the specific rooms R1, R2, R3, R4 water starts to flow from the incoming water supply 15 to its respective injection devices 2a, 2b, 2c, 2d. Upon detecting the flow of water in the injection devices 2a, 2b, 2c, 2d, the flow switches 3a, 3b, 3c, 3d send signals to the system controller 7 to send signals to the ozone generator 6a, 6b, 6c and the shared ozone generator 6e to generate ozone. The ozone generated from the ozone generators 6a, 6b, 6c and the shared ozone generator 6e is supplied to the injection devices 2a, 2b, 2c, 2d respectively to initiate the mixing of the ozone with the flow of water in the injection devices 2a, 2b, 2c, 2d to form ozone water. The ozone water formed in the injection devices 2a, 2b, 2c, 2d is distributed to the rooms R1, R2, R3, R4 respectively in which a flow of water is detected in the respective injection devices 2a, 2b, 2c, 2d. The ozone water is distributed to the plurality of rooms R1, R2, R3, R4 through the delivery piping system 8.

[0050] FIG. 4 is a block diagram which illustrates a fourth embodiment of a distributed sterilizer system 400 which comprises all the components of the second embodiment for providing ozone water to a plurality of rooms T1, T2, T3 except the plurality of flow switches and an addition of an output tubing 14 for distributing unused ozone from the ozone generators, 6a, 6b, 6c to the plurality of other rooms T5, T6, T7. In this embodiment, the forming and distribution of ozone water to a plurality of rooms T1, T2, T3 and ozone to a plurality of other rooms T5, T6, T7 is determined by a time-based configuration using the timer 12. The plurality of rooms T1, T2, T3, are washrooms in which the ozone water is used for cleaning in the toilet bowls, basins, bidets and urinals. The plurality of other rooms T5, T6, T7 are washrooms in which the ozone is used to sterilize the surrounding air in the rooms. In this embodiment, an ozone generator 6d in the ozone generation system 1 serves as a dedicated ozone generator for supplying ozone directly to the plurality of other rooms T5, T6, T7 through the series of output tubing 10 and air nozzles 11.

[0051] The timer 12 selectively operates the plurality of ozone generators 6a, 6b, 6c and the dedicated ozone generator 6d of the ozone generation system 1 between on and off states by defining the duration of the time intervals for the OFF and ON states. According to the time interval, the plurality of ozone generators 6a, 6b, 6c and the dedicated ozone generator 6d generates and supplies ozone to the plurality of injection devices 2a, 2b, 2c and directly to the plurality of rooms T5, T6, T7, respectively.

[0052] The duration of the time intervals is configured by the user. For example, in this embodiment, the interval time is 15 minutes. The ozone generators 6a, 6b, 6c and the dedicated ozone generator 6d are switched OFF for an interval time of 15 minutes. After the interval 15 minutes ends, the ozone generators 6a, 6b, 6c and the dedicated ozone generator 6d are switched ON again for the next 15 minutes before it is switched OFF again.

[0053] During the interval time of 15 minutes in which the ozone generators 6a, 6b, 6c and the dedicated ozone generator 6d are switched ON, the system controller 7 sends signals to the centralized oxygen concentrator 5 to supply oxygen to the ozone generators 6a, 6b, 6c and the dedicated ozone generator 6d. The ozone generators 6a, 6b, 6c and the dedicated ozone generator 6d generate a supply of ozone to be supplied and distributed to the plurality of injection devices 2a, 2b, 2c and directly to the plurality of rooms T5, T6, T7, respectively. The ozone distributed from the ozone generator 6a, 6b, 6c to the injection device 2a, 2b, 2c remains available in the injection devices 2a, 2b, 2c respectively for the process of mixing subjected to a demand by the users in any of the respective rooms T1, T2, T3. At any time during the interval time of 15 minutes, when a user opens any of the water outlets 9a, 9b, 9c in the plurality of rooms, T1, T2, T3 respectively, water from the incoming water supply 15 starts to flow into the injection devices 2a, 2b, 2c. The available supply of the ozone generated from the ozone generators 6a, 6b, 6c at the interval time of 15 minutes is mixed with the flow of water in the injection devices 2a, 2b, 2c to form ozone water. The ozone water from the injection devices 6a, 6b, 6c is distributed to the water outlets 9a, 9b, 9c accordingly. In the event that the water outlets 9a, 9b, 9c are closed at any time during the interval time of 15 minutes and no water flows into the injection devices 2a, 2b, 2c, the unused ozone generated from the ozone generators 6a, 6b, 6c is channeled to the plurality of other rooms T5, T6, T7 through an output tubing 14.

[0054] For example, at any time during the interval time of 15 minutes, when a user opens a water outlet 9a in room T1, water from the incoming water supply 15 starts to flow into the injection device 2a. The supply of the ozone generated from the ozone generator 6a at the interval time of 15 minutes is mixed with the flow of water in the injection device 2a to form ozone water. The ozone water is supplied to the water outlet 9a. In the event that the water outlet 9a is closed at any time during the interval time of 15 minutes and no water flows into the injection device 2a, the unused ozone generated from the ozone generator 6a is channeled to the plurality of other rooms T5, T6, T7 through an output tubing 14.

[0055] During the interval time of 15 minutes in which the dedicated ozone generator 6d is switched ON, the dedicated ozone generator 6d generates a supply of ozone to be distributed directly to the plurality of other rooms T5, T6, T7 through the series of tubing 10 and air nozzles 11.

[0056] FIG. 5 is a block diagram which illustrates a fifth embodiment of a distributed sterilizer system 500 which comprises all the components of the third embodiment for providing ozone water to a plurality of rooms T1, T2, T3 except the plurality of flow switches and an addition of an output tubing 14 for distributing unused ozone to the plurality of other rooms T5, T6, T7. In this embodiment, the forming and distribution of ozone water to a plurality of rooms T1, T2, T3 and ozone to a plurality of other rooms T5, T6, T7 is determined by a time-based configuration using the timer 12. The plurality of rooms T1, T2, T3, are washrooms in which the ozone water is used for cleaning in the toilet bowls, basins, bidets and urinals. The plurality of other rooms T5, T6, T7 are washrooms in which the ozone is used to sterilize the surrounding air in the rooms. In this embodiment, an ozone generator 6e in the ozone generation system 1 serves as a shared ozone generator tor supplying ozone directly to the plurality of other rooms T5, T6, T7 and to an injection device 2d.

[0057] During the interval time of 15 minutes in which the ozone generators 6a, 6b, 6c and the shared ozone generator 6e are switched ON, the system controller 7 sends signals to the centralized oxygen concentrator 5 to supply oxygen to the ozone generators 6a, 6b, 6c and the shared ozone generator 6e through plurality of oxygen flow meters, 5a, 5b, 5d, 5e respectively. The ozone generators 6a, 6b, 6c and the shared ozone generator 6e generate a supply of ozone to be supplied and distributed to the plurality of injection devices 2a, 2b, 2c, 2d and directly to the plurality of rooms T5, T6, T7, respectively. The supply of ozone generated from the shared ozone generator 6e is shared and distributed to the plurality of other rooms T5, T6, T7 through the series of output tubing 13 and air nozzles 11 and to the injection device 2d for supplying ozone water to the room T4.

[0058] At any time during the interval time of 15 minutes, when a user opens any of the water outlets 9a, 9b, 9c, 9d in the plurality of rooms, T1, T2, T3, T4 respectively, water starts to flow from the incoming water supply 15 into the injection devices 2a, 2b, 2c, 2d. The supply of the ozone generated from the ozone generators 6a, 6b, 6c and the shared ozone generator 6e at the interval time of 15 minutes is mixed with the flow of water in the injection devices 2a, 2b, 2c, 2d respectively to form ozone water. The ozone water is distributed to the water outlets 9a, 9b, 9c, 9d accordingly. In the event that any of the water outlets 9a, 9b, 9c, 9d are closed at any time during the interval time of 15 minutes and no water flows into the injection devices 2a, 2b, 2c, 2d, the unused ozone generated from the ozone generators 6a, 6b, 6c and the shared ozone generator 6e is channeled to the plurality of other rooms T5, T6, T7 through an output tubing 14.

[0059] For example, at any time during the interval time of 15 minutes, when a user opens a water outlet 9d in room T4, water from the incoming water supply 15 starts to flow into the injection device 2d. The available supply of the ozone generated from the shared ozone generator 6e at the interval time of 15 minutes is mixed with the flow of water in the injection device 2d to form ozone water. The ozone water is supplied to the water outlet 9d. In the event that the water outlet 9d is closed at any time during the interval time of 15 minutes and no water flows into the injection device 2d, the unused ozone generated from the ozone generator 6e is channeled to the plurality of other rooms T5, T6, T7 through on output tubing 14.

[0060] FIG. 6 illustrates close-up views of injection devices in which FIG. 6A illustrates an injection device which functions based on a time-based configuration in FIG. 6A and FIG. 6B illustrates an injection device which functions based on a demand-based configuration.

[0061] FIG. 6A illustrates a close-up view of an injection device 2a, 2b, 2c, 2d which is used in the fourth and fifth embodiments which are based on a time-based configuration. The injection device in FIG. 6A facilitates the mixing of a supply of water from the incoming water supply 15 with the ozone generated from the ozone generator (shown in FIG. 4 or 5) according to a predetermined time-interval to form ozone water. The ozone water is distributed to the plurality of rooms T1, T2, T3. The plurality of rooms, T1, T2, T3 are washrooms in which the ozone water is used for cleaning in the toilet bowls, basins, bidets and urinals. When a water outlet (shown in FIG. 4 or 5) in any of the rooms T1, T2, T3 is opened, a supply of water from the incoming water supply 15 flows into a venturi device in the injection device 2a, 2b, 2c, 2d. This supply of water in the venturi device is available for mixing with the ozone generated from the ozone generator (shown in FIG. 4 or 5). The supply of ozone is generated based on a pre-determined time interval in which the system controller (shown in FIG. 4 or 5) sends signals to the ozone generation system (shown in FIG. 4 or 5) to generate ozone. The ozone is distributed into the venturi device in the injection device 2a, 2b, 2c, 2d for the mixing process to form ozone water. In the event, no water outlet is opened in any of the rooms T1, T2, T3, the unused ozone will remain in the venturi device and eventually be channeled to any of the other plurality of rooms (shown in FIG. 4 or 5). In between the time-interval in which the ozone generation system (shown in FIG. 4 or 5) is switched OFF, the opening of a water outlet in any of the rooms T1, T2, T3 during this time triggers the flow of water into the venturi device to mix with the remaining unused ozone supplied from the previous cycle to form ozone water.

[0062] FIG. 6B illustrates a close-up view of an injection device 2a, 2b, 2c, 2d which is used in the first, second and third embodiments which are based on a demand-based configuration. The injection device 2a, 2b, 2c, 2d is incorporated with a flow switch 3a, 3b, 3c, 3d which facilitates the mixing of a supply of water from the incoming water supply 15) with the ozone generated from the ozone generator (shown in FIG. 1, 2 or 3) to form ozone water. The ozone water is distributed to the plurality of rooms R1, R2, R3. The plurality of rooms, R1, R2, R3 are sections in a kitchen area in which the ozone water is used for washing in the washing section, butchery section and food preparation section. When a water outlet (shown in FIG. 1, 2 or 3) in any of the rooms R1, R2, R3 is opened, a supply of water the incoming water supply 15) flows into a venturi device in the injection device 2a, 2b, 2c, 2d. The flow of water into the venturi device triggers the flow switch 3a, 3b, 3c, 3d to send a signal to the system controller (shown in FIG. 1, 2 or 3) to send signals to the ozone generation system (shown in FIG. 1, 2 or 3) to generate and supply ozone to the injection device 2a, 2b, 2c, 2d. The ozone generated from the ozone generator (shown in FIG. 1, 2 or 3) is distributed to the venturi device for mixing with the supply of water to form ozone water. The ozone water is distributed to the plurality of rooms R1, R2, R3.
