Description

Technical Field

[0001] The present invention relates to an ozone water floor disinfection system, and in particular to an ozone water floor disinfection system capable of tracking the service life of an ozone water generator and performing GPS geo-fencing on the disinfected floor surface. Background Art

[0002] At present, floor cleaning machines are used to clean floor surfaces. Existing floor cleaning machines have the following disadvantages: 1. Many floor cleaning machines use a combination of water and detergent that is applied to the floor surface and then vacuumed. Although many existing floor cleaning machines appear to clean the floor surface, they do not disinfect the floor in any meaningful way.

[0003] 2. The floor cleaning machine disinfects the floor surface by applying any chemical or disinfecting technology to the same location currently being cleaned, that is, attempting to clean and disinfect the same location on the floor surface at the same time. This method cannot effectively disinfect the floor surface.

[0004] 3. The disinfection effect of floor cleaning machines will degrade over time. In this regard, perhaps the disinfection effect is good when it is used and shortly after use, but if technicians do not have a way to confirm performance and / or remotely monitor system performance, the disinfection system may not be able to disinfect adequately for most of the time it is used, and no one will know that consumables in the system need to be repaired or replaced.

[0005] 4. The floor cleaning machine does not track or image the floor areas that have been disinfected, and does not know when the disinfection was performed and on which floor surface the disinfection was applied. Summary of the invention

[0006] The object of the present invention is to overcome the above-mentioned deficiencies of the prior art and to provide an ozone water floor disinfection system.

[0007] The ozone water floor disinfection system includes a cleaning mechanism. The cleaning mechanism is capable of passing through a floor surface and cleaning the floor surface. An ozone water generator receives water and generates an ozone concentrate from the water. A mixer receives and mixes a portion of the ozone concentrate with the water in proportion to form an ozone disinfection solution of a desired ozone concentration level. A nozzle sprays the ozone disinfection solution onto the floor surface that has been cleaned by the cleaning mechanism.

[0008] The present invention provides a method of using an ozone water floor disinfection system to overcome other disadvantages of the prior art and provide additional advantages. The method includes the steps of operating a cleaning mechanism on a floor surface and generating an ozone concentrate from water using an ozone generator.

[0009] The method includes receiving and mixing a portion of the ozone concentrate and water in a proportion with a mixer to form an ozone disinfecting solution with a desired ozone concentration level, and spraying the ozone disinfecting solution onto the floor surface cleaned by the cleaning mechanism with a nozzle.

[0010] The present invention provides an ozone water floor disinfection system to overcome other shortcomings of the prior art and provide additional advantages. The ozone water floor disinfection system includes a water source and a floor cleaning machine. The floor cleaning machine includes a cleaning mechanism. The floor cleaning machine can pass through the floor surface before cleaning and enter the pre-sanitation area. The cleaning mechanism is used to clean in the sanitation area for a cleaning period of time, and leaves the sanitation area to form a post-sanitation area.

[0011] The ozone water floor disinfection system further includes an ozone water generator that receives a portion of the water source and produces an ozone concentrate from the water source. The ozone water generator includes a pipe housing fastened in a fluid communication path with the water source and the ozone concentrate and an electrochemical generator. The electrochemical generator includes an ion exchange material. The electrochemical generator is interchangeable and removably fastened to the pipe housing.

[0012] The ozone water floor disinfection system further includes a fixed volume inspection chamber that receives continuous fluid and maintains a fixed volume portion of the ozone concentrate or the post-sanitation ozone disinfection solution. The number of the fixed volume portion is predetermined based on the test requirements of the ozone concentration test device.

[0013] The ozone water floor disinfection system further includes a post-sanitation mixer that receives and mixes a portion of the ozone concentrate and a portion of the water source in proportion to form a post-sanitation ozone disinfection solution having a predetermined post-sanitation ozone treatment concentration. The ozone concentration of the post-sanitation ozone disinfection solution is less than the ozone concentration of the ozone concentrate. The predetermined post-sanitation ozone treatment concentration is selected to achieve disinfection of the floor surface within a post-sanitation treatment time. The post-sanitation treatment time is greater than the cleaning time.

[0014] The ozone water floor disinfection system further comprises a post-sanitation nozzle mounted on the floor cleaning machine near the transition between the sanitary zone and the post-sanitation zone. The post-sanitation nozzle sprays the post-sanitation ozone disinfection solution to the post-sanitation zone of the floor surface.

[0015] In operation, cleaning within the mid-sanitation zone removes debris from the floor surface, allowing the post-sanitation ozone disinfecting solution sprayed on the post-sanitation zone to contact the floor surface in a manner unimpeded by debris for at least the post-sanitation treatment time, which can improve disinfection of the floor surface without agitation or removal by the floor cleaning machine.

[0016] In operation, the ozone concentration test device includes at least one of the following: an ozone concentration test strip, an ozone concentration test drop, or an ozone concentration test device. A technician manually uses the ozone concentration test device, inserts the ozone concentration test device into the fixed volume inspection chamber to determine the test ozone concentration of the ozone concentrate or the post-sanitation ozone disinfection solution, and then reads the test ozone concentration in the ozone concentrate or the post-sanitation ozone disinfection solution.

[0017] The present invention provides a method of using an ozone water floor disinfection system to overcome other disadvantages of the prior art and provide additional advantages. The method includes the steps of operating a floor cleaning machine to clean a floor surface. The floor cleaning machine includes a cleaning mechanism.

[0018] The method comprises crossing the floor surface. The floor cleaning machine enters the pre-sanitary area before cleaning, cleans in the sanitation area for a cleaning time by the cleaning mechanism, and then leaves the sanitation area to form a post-sanitation area.

[0019] The method includes generating an ozone concentrate. An ozone water generator receives a portion of a water source and generates the ozone concentrate from the water source.

[0020] The method includes producing a post-sanitation ozone disinfection solution at a predetermined post-sanitation ozone treatment concentration. A post-sanitation mixer receives and mixes a portion of the ozone concentrate and a portion of the water source in proportion to form the post-sanitation ozone disinfection solution having the predetermined post-sanitation ozone treatment concentration. The predetermined post-sanitation ozone treatment concentration is less than the ozone concentration of the ozone concentrate. The predetermined post-sanitation ozone treatment concentration is selected to achieve disinfection of the floor surface within a post-sanitation treatment time. The post-sanitation treatment time is greater than the cleaning time.

[0021] The method includes disinfecting the post-sanitation area. A post-sanitation nozzle is mounted on the floor cleaning machine proximate the transition between the mid-sanitation area and the post-sanitation area. The post-sanitation nozzle sprays the post-sanitation ozone disinfectant solution to the post-sanitation area of ​​the floor surface. In operation, cleaning in the mid-sanitation area removes debris from the floor surface, allowing the post-sanitation ozone disinfectant solution sprayed on the post-sanitation area to contact the floor surface in a manner unimpeded by debris without agitation or removal by the floor cleaning machine for at least the post-sanitation treatment time to improve disinfection of the floor surface.

[0025] The detailed description explains the preferred embodiments of the invention, together with advantages and features, by way of example with reference to the drawings, and such illustrations should not be construed as limiting the scope of the invention in any way. DETAILED DESCRIPTION

[0026] like Figure 1As shown, in the ozone water floor disinfection system 100, the floor cleaning machine 202 may include a cleaning mechanism 220, which may include items such as a cleaning agent, a brush, a spray nozzle, a vacuum cleaner, and other items depending on the type or kind of the floor cleaning machine.

[0027] The advantage of the present invention is that the manufacture of ozone water is carried out in water, and there is no air or oxygen traditionally used for corona discharge ozone manufacture. The advantage of ozone water is that it can form ozone O3 molecules in large quantities from water on demand with the help of ion exchange materials. Ozone molecules are produced in high concentrations and are fully distributed in the whole water, and are not easy to decompose from water, so that the ozone concentration in the aqueous solution dissipates slowly, and the half-life is between 20-30 minutes. In this regard, ozone water is sprayed on the clean floor in the hygienic rear area 204C, and the ozone that is not distributed by the floor cleaning machine is slowly dried, which means that the ozone treatment time (after-T3) 210 can vary from several minutes to tens of minutes. The long half-life of ozone water is combined with the treatment of the clean floor surface with sufficient ozone concentration in the hygienic rear area 204C, so that the present invention can reach the condition of sterile or near sterile floor surface 204.

[0028] Conversely, a corona discharge system produces ozone gas (along with a bunch of nitrogen molecules that are harmful to humans) that then has to be dissolved or dispersed into water at low concentrations, from where it will easily break down and dissipate before it can provide a true disinfecting benefit to the floor surface. Also, ozone water has an ozone purity in the 28% range, and corona discharge technology produces ozone with a purity in the mid-single digits to low teens, with corona discharge in air producing less purity than corona discharge in oxygen.

[0029] In operation, the floor cleaning machine 202 can move along the floor surface 204, dispense cleaning agents, and use a brush and vacuum cleaner to remove debris from the floor surface. In this regard, the floor cleaning machine 202 can traverse the floor surface 204 before cleaning, enter the pre-sanitation area 204A, perform cleaning in the sanitation area 204B for a cleaning time (mid-T2) 208 through the cleaning mechanism 220, and then leave the sanitation area 204B to form a post-sanitation area 204C.

[0030] Reference Figure 1One advantage of the present invention is that the pre-sanitary zone 204A of the floor surface 204 is located before the location that the floor cleaning machine 202 will next clean as it moves along the floor surface. The present invention can ozone disinfect each of the three zones and select different levels of ozone concentration based on the amount of treatment time available. In this regard, within the pre-sanitary zone 204A, there is an ozone disinfection time (pre-T1) 206, which is established in part based on the speed of the floor cleaning machine 202, during which the floor cleaning machine 202 equipped with the pre-sanitary nozzle 112 can spray a pre-sanitary ozone disinfection solution having a predetermined pre-sanitary ozone treatment concentration before the floor cleaning machine 202 displaces the pre-sanitary ozone disinfection solution to clean the floor surface.

[0031] Next, there is a second ozone disinfection time (mid-T2) 208, which is established in part based on the speed of the floor cleaning machine 202, during which the floor cleaning machine 202 actively uses detergents, brushes and other items to clean the sanitary middle area 204B portion of the floor surface 204. If equipped with a sanitary middle nozzle 114, when the floor cleaning machine 202 cleans the sanitary middle area 204B of the floor surface 204, a sanitary middle ozone disinfection solution having a predetermined sanitary middle ozone treatment concentration can be sprayed in the sanitary middle area 204B.

[0032] Next, there is a third ozone disinfection time (after-T3) 210, which is generated when the floor cleaning machine 202 moves away from the sanitary area 204B after cleaning, thereby generating a sanitary area 204C. If equipped with a sanitary nozzle 116, a sanitary ozone disinfection solution with a predetermined sanitary ozone treatment concentration can be sprayed into the sanitary area 204C and dried by evaporation. In this regard, after cleaning the floor surface 204 and removing debris, the sanitary ozone disinfection solution will be more likely to contact the floor surface, and since it will not be disturbed until it is air-dried after being sprayed on the floor surface 204, the contact treatment time (after-T3) 210 can be very long, thereby maximizing the killing time of bacteria, mold, mildew, and other pathogens, so that the floor surface 204 can reach a sterile or near-sterile condition.

[0033] One advantage of the present invention is that the pre-sanitation ozone disinfection solution sprayed from the nozzle 112, the mid-sanitation ozone disinfection solution sprayed from the nozzle 114, and the post-sanitation ozone disinfection solution sprayed from the nozzle 116 can be mixed in proportion (ratio of water 102 and ozone concentrate 118) to have different ozone water concentrations (O3ppm). These different ozone water concentrations are referred to as the predetermined pre-sanitation ozone treatment concentration, the predetermined mid-sanitation ozone treatment concentration, and the predetermined post-sanitation ozone treatment concentration.

[0034] In this regard, in an exemplary embodiment, since the pre-T1 206, mid-T2 208, and post-T3 210 vary in duration, the concentration of the ozone disinfecting spray may be selected accordingly, with shorter time periods receiving higher ozone concentrations.

[0035] In another exemplary embodiment, in addition to the variation in floor surface 204 contact time (front-T1 206, middle-T2 208, and back-T3 210), the concentration of the ozone disinfecting spray may also be selected or adjusted based on the initial conditions of the condition of the floor surface 204. In this regard, the pre-sanitation zone 204A includes the floor surface 204 covered with debris, the mid-sanitation zone 204B includes water, detergent, brush agitation, and debris, and the post-sanitation zone 204C includes only the clean floor surface 204.

[0036] In another exemplary embodiment, since the duration of pre-T1 206 and mid-T2 208 depends on the moving speed of the floor cleaning machine 204, the proportion of the water 102 and the ozone concentrate 118 can be dynamically changed according to the speed of the floor cleaning machine 204. In this regard, the ozone water floor disinfection system 100 can be configured to monitor the speed of the floor cleaning machine, and as the speed increases, the ozone disinfection spray contact time from the nozzle 112 in the pre-sanitation area 204A during the duration of pre-T1 206 can be shortened, and the predetermined pre-sanitation ozone treatment concentration and the predetermined mid-sanitation ozone treatment concentration from the nozzle 114 in the mid-sanitation area 204B can be increased accordingly during the duration of mid-T2 208. Vice versa, as the cleaning machine speed decreases, the ozone disinfecting spray contact time from the nozzle 112 in the pre-sanitation zone 204A during the duration of pre-T1 206 increases, and the predetermined pre-sanitation ozone treatment concentration and the predetermined mid-sanitation ozone treatment concentration from the nozzle 114 in the mid-sanitation zone 204B during the duration of mid-T2 208 decrease accordingly.

[0037] In the present invention, the term "proportional" or "proportionately" means a system in which the output is proportional to the input. In this regard, the output in the ozone water mixture is the ratio of ozone concentrate to water. An advantage of the present invention is that the ozone concentration of the ozone concentrate can be higher than the desired concentration and can be diluted with water in proportion to achieve the desired ozone concentration. In addition, the ozone concentrate can be proportionally mixed with water through different mixers to produce ozone water with different ozone concentrations, which can be used in exemplary embodiments of the present invention. Another advantage is that, instead of batch technology, no matter how much flow rate of effluent solution is required, proportional mixing of water and ozone concentrate can accurately produce the required flow rate at the appropriate ozone concentration at any required flow level.

[0038] In operation, refer to Figure 5 Marked "A", mixing may be performed using a fixed orifice manifold 140 where each orifice 316 / 318 has a different diameter to produce the desired ratio of water 126 and ozone concentrate 124 to form a single effluent 134 to the nozzles 112 / 114 / 116.

[0039] In an exemplary embodiment, the pre-sanitary mixer 106, the mid-sanitary mixer 108, and the post-sanitary mixer 110 may include a water inlet 142 for receiving the water source 102, a concentrate inlet 144 for receiving the ozone concentrate 118 / 124, and a single mixed effluent 134. The flow rate through the water inlet 142 and the concentrate inlet 144 is 316 / 318 to passively mix the pre-sanitary ozone disinfection solution of the predetermined pre-sanitary ozone treatment concentration, the mid-sanitary ozone disinfection solution of the predetermined mid-sanitary ozone treatment concentration, and the post-sanitary ozone disinfection solution of the predetermined post-sanitary ozone treatment concentration. For the purpose of disclosure and illustration, in multiple exemplary embodiments, at least one of the pre-sanitary mixer 106, the mid-sanitary mixer 108, or the post-sanitary mixer 110 may be incorporated into the system, not all three in every example.

[0040] Or, refer to Figure 5 and Figure 7 , the fixed hole type manifold 140 may have holes 320 of the same size, and the pump / valve 528 / 532 may be used to distribute the water 126 and the ozone concentrate 124 under control 414 / 416 to produce the desired ratio of water and ozone concentrate to the nozzles 112 / 114 / 116. The advantage of using the pump 528 / 532 and the control system 500 timing 414 / 416 is that the concentration of the ozone water mixture can be dynamically changed. In this regard, as the floor cleaning machine 202 accelerates or decelerates, as well as other reasons and circumstances, the concentration of the ozone water mixture passing through the nozzle 106 / 108 / 110 can be changed by adjusting the pulse width timing 414 / 416 of the operating pump 528 / 532. Including stopping the pulse width generation to stop mixing and spraying the ozone water mixture through the nozzle 106 / 108 / 110.

[0041] One advantage of the present invention is that the ozone water generator 530 can generate ozone through water electrolysis and ion exchange technology. In this regard, a portion of the ozone water generator 530 may include an electrochemical generator 516. During normal operation, the process of generating ozone water can degrade the ozone water generator 530. In addition, water quality can also have an impact on the ozone water generator 530, including causing premature scaling of certain components. This requires tracking the service life of the ozone water generator 530 and components such as the electrochemical generator 516. The present invention achieves this goal in several different ways.

[0042] In an exemplary embodiment, technician 302 can manually test the ozone water and communicate the results to a remote data processing resource 702 (e.g., server 702) via a computing device 732 (e.g., a laptop, smartphone, tablet, or other suitable computing device). Ozone generation, use of the ozone water generator, and ozone concentration levels can all be tracked remotely over time. When the data indicates that maintenance or replacement is required, a notification can be sent to technician 302 or manager 304 to repair or replace the water ozone generator 530.

[0043] In another exemplary embodiment, the control system 500 may include an ozone sensor 522 and a communication interface 508 that may automatically monitor ozone generation and use of the ozone water generator 530. The result may be data that is transmitted to the remote data processing resource 702 for recording via the communication interface 508. When the data indicates that maintenance or replacement is required, a notification may be transmitted to the technician 304 or the manager 304 to repair or replace the water ozone generator 530.

[0044] refer to Figure 1 In another advantage of the present invention, the control system 500 may include a global positioning system (GPS) 514. In this regard, the GPS location of the floor cleaning machine 202 during use, and more specifically, the area that has been treated by the ozone water floor disinfection system, may be monitored and tracked, and the data may be transmitted to the remote data processing resource 702 via the communication interface. Reports, maps, and other information may then be used to inform the location, time, and other details of the ozone disinfection of the floor surface 204, as may be required and / or desired in a particular embodiment.

[0045] refer to Figure 1 , labeled "A" shows a system diagram of an ozone water floor disinfection system. During operation, water 102 is delivered to an ozone water generator 530. Through electrolysis and ion exchange technology, the ozone water generator 530 can produce an ozone concentrate 118. The concentration of the ozone concentrate 118 can be much higher than the concentration distributed to the floor surface 204. In this regard, the ozone concentrate 118 can be delivered to the mixer 106 / 108 / 110 via a prescribed route 120. In addition, the water 102 can be delivered to the mixer 106 / 108 / 110 via a prescribed route 104. Such routes 104 / 120 and other types and kinds of routes can be pipes or other suitable fluid communication means, as may be required and / or desired in a particular embodiment.

[0046] Each mixer 106 / 108 / 110 mixes water 102 and ozone concentrate 118 in proportion to each other into an ozone treatment concentration solution, and then sprays it on different areas 204A / 204B / 204C of the floor surface 204. In this regard, the pre-sanitary proportioning mixer 106 mixes a pre-sanitary ozone disinfection solution having a predetermined pre-sanitary ozone treatment concentration, which can be sprayed in the pre-sanitary area 204A through the nozzle 112. Correspondingly, the mid-sanitary proportioning mixer 108 mixes a mid-sanitary ozone disinfection solution having a predetermined mid-sanitary ozone treatment concentration, which can be sprayed in the mid-sanitary area 204B through the nozzle 114. Correspondingly, the post-sanitary proportioning mixer 110 mixes a post-sanitary ozone disinfection solution having a predetermined post-sanitary ozone treatment concentration, which can be sprayed in the post-sanitary area 204C through the nozzle 116.

[0047] One advantage of the present invention is that different concentrations of dissolved ozone can be mixed in proportion and sprayed from each nozzle 112 / 114 / 116. In this regard, the predetermined pre-sanitation ozone treatment concentration can be different from the predetermined mid-sanitation ozone treatment concentration, and the predetermined mid-sanitation ozone treatment concentration can be different from the predetermined post-sanitation ozone treatment concentration. In operation, since the floor surface 204 is in different states in the pre-sanitation area 204A (uncleaned with debris), the mid-sanitation area 204B (during cleaning using agitation, water, detergent and debris), and the post-sanitation area 204C (clean), different types of treatment concentration levels are required, and therefore the dissolved ozone concentration can be applied to the floor surface 204 at different concentrations.

[0048] Additionally, if high concentrations of ozone are desired, the high concentrations of ozone must be isolated from contact with the technician 302, or the ozone odor must be minimized during the cleaning process by applying a higher concentration ozone treatment to the sanitary area 204B as part of the cleaning and then removed from the floor surface along with the water, detergent, and debris.

[0049] refer to Figure 1 , labels "B" and "C" show examples of floor cleaning machines 202 that use brushes, cleaning agents sprayed on the floor surface, vacuum cleaners and other components to clean and remove dirty waste liquid from the floor surface. In general, the present invention can be integrated into new floor cleaning machines 202 that lack sufficient floor surface disinfection capabilities or retrofitted into old floor cleaning machines 202.

[0050] One advantage of the present invention is that when considering the floor cleaning machine 202 moving 212 along the floor surface 204, three zones are defined. In this regard, the pre-sanitation zone 204A or pre-cleaning zone transitions 216 to the mid-sanitation zone 204 or the zone currently being cleaned by the cleaning mechanism of the floor cleaning machine 204, and transitions 214 to the post-sanitation zone 204C or the cleaned floor surface. Although some embodiments of the present invention seek to treat two or more zones (the pre-sanitation zone 204A, the mid-sanitation zone 204B, and / or the post-sanitation zone 204C) at different ozone concentration levels, the present invention can also achieve a high level of floor surface disinfection, even to sterile or near-sterile conditions, and achieve a 5 log reduction oxidation level of pathogens (including odor-causing pathogens such as mold and others) under disinfected conditions on the floor surface 204 simply by using the post-sanitation mixer 110 and nozzle 116 to spray the post-sanitation ozone disinfection solution having a predetermined post-sanitation ozone treatment concentration in the post-sanitation zone 204C. In this regard, the post-sanitation ozone disinfection solution, when sprayed with sufficient ozone concentration levels, can achieve a 5 log reduction oxidation level of pathogens (including odor-causing pathogens such as mold and others) on the floor surface 204C under sterile or near-sterile conditions. In the post-sanitation disinfection area 204C, immediately after the floor surface 204 in the mid-sanitation disinfection area 204B is cleaned of debris, the post-sanitation ozone disinfection solution can remain undisturbed, undisturbed, and undiluted by cleaning fluid for a long treatment time (post-T3) 210 to allow for air drying.

[0051] In an exemplary embodiment, the ozone water floor disinfection system 100 may include an ozone water generator 530 that receives a portion of the water source 102 and produces an ozone concentrate 118 from the water source 102. Such ozone water generation may be performed by an electrochemical generator 516. The electrochemical generator 516 may be integrated into the ozone water generator 530. In addition, the electrochemical generator 516 may include an ion exchange material 534 that facilitates the formation / generation of ozone molecules. In operation, the ozone water generator 530 may use electrolysis in combination with the ion exchange material 534, other coatings, electronic control signals, pulse width modulation, and / or other techniques, technologies, and signal processing to produce an ozone concentrate in the range of one part per million (ppm) of ozone or other desired lower limit to 10 ppm or other desired upper limit, depending on several factors. These factors may include the structure of the ozone water generator 530, the electrochemical generator 516, the amount of ozone concentrate 118 generated at one time, the time the ozone water generator 530 generates the ozone concentrate 118, the amount of current passing between the electrodes and the surface area of ​​the electrodes, as well as other factors.

[0052] Although the types and types of components in the ozone water generator 530, and particularly the electrochemical generator 516, are selected to promote maximum useful life of the electrochemical generator 516, the process of manufacturing the ozone concentrate 118 consumes certain materials in the ozone water generator 530 and / or the electrochemical generator 516, and therefore it is necessary to monitor the useful useful life of the ozone water generator 530.

[0053] Furthermore, during normal use of the ozone water generator 530 and / or the electrochemical generator 516 , the type or kind of water used in the generator may affect the production (quantity and production rate) of ozone water, as well as cause undesirable scaling of the electrodes, thereby adversely affecting the production of ozone concentrate 118 .

[0054] In an exemplary embodiment, the control system 500 can monitor and adjust the current between the electrodes via the current sensor 520. In this regard, the amount of current provided to the ozone water generation is adjusted to overcome slight degradation of the consumable electrodes and other factors that typically flow through the water during the ozone water generation process.

[0055] Adjusting the current helps produce consistent and reliable ozone water at a desired ppm concentration, and the control system 500 can determine the degree of compensation required under nominal conditions, such as when the ozone water generator 530 is first installed. Such current monitoring and adjustment details can be reported or otherwise transmitted to a remote data processing resource 702, such as a server 702, via the communication interface 508. This monitoring and tracking of current usage and changes over time, along with other factors, can be used to predict the useful life of the ozone water generator 530 and provide notification to the technician 302 or administrator 304 when it is necessary to schedule maintenance and / or replacement of the ozone water generator 530.

[0056] In addition to predictive maintenance and lifecycle notifications for ozone water generating components, changes in water 102 quality, or aqueous mineral scaling on ozone water generator 530 components, may also be detected and a technician 302 or manager 304 notified to take necessary corrective action.

[0057] In an illustrative example, during operation, when ozone disinfection of the post-sanitation area 204C is required, the post-sanitation mixer 116 receives and mixes a portion of the ozone concentrate 118 and a portion of the water source 102 in proportion to form a post-sanitation ozone disinfection solution having a predetermined post-sanitation ozone treatment concentration (based on the mixing ratio of the water 102 and the ozone concentrate 118), and the ozone concentration of the post-sanitation ozone disinfection solution will be less than the ozone concentration of the ozone concentrate 118. In this regard, the ozone concentrate 118 mixture will be diluted with water to the desired ozone concentration level (ppm).

[0058] In operation, a predetermined post-sanitation ozone concentration is selected to achieve a sterilizing or near sterilizing condition of the floor surface 204 within a post-sanitation time (post-T3) 210. In this regard, the post-sanitation time is greater than the cleaning time (mid-T2) 208. The post-sanitation nozzle 116 is mounted on the floor cleaning machine 202 near a transition 214 between the mid-sanitation zone 204B and the post-sanitation zone 204C.

[0059] In operation, cleaning within the mid-sanitation zone 204B removes debris from the floor surface 204, allowing the post-sanitation ozone disinfecting solution sprayed on the post-sanitation zone 204C to contact the floor surface in a manner unimpeded by debris for at least a post-sanitation treatment period, which can improve the disinfection of the floor surface without agitation or removal by the floor cleaning machine 202.

[0060] In an exemplary embodiment, during operation, when ozone disinfection of the sanitary zone 204B is required, the sanitary mixer 108 receives and mixes a portion of the ozone concentrate 118 and a portion of the water source 102 in proportion to form a sanitary ozone disinfection solution having a predetermined sanitary ozone treatment concentration.

The predetermined pre-sanitation ozone treatment concentration is selected to achieve disinfection of debris on the floor surface 204 within a pre-sanitation treatment time (pre-T1) 206. The pre-sanitation treatment time (pre-T1) 206 is less than a cleaning time (mid-T2) 208. The pre-sanitation nozzle 112 is mounted on the floor cleaning machine 202 near a transition 216 between the mid-sanitation area 204B and the pre-sanitation area 204A. The pre-sanitation nozzle 112 sprays the pre-sanitation ozone disinfection solution onto the pre-sanitation area 204A portion of the floor surface 204.

[0089] In an exemplary embodiment, the post-sanitation pump 528D / 532C may be configured to control the outflow of the post-sanitation ozone disinfecting solution from the post-sanitation nozzle 116. The post-sanitation pump 528D / 532C may be configured to push the water 102 and the ozone concentrate 118 under pressure through the post-sanitation mixer 110 and out of the post-sanitation nozzle 116, as shown in FIG. Figure 2 As shown, alternatively, the post-sanitation pump can be configured on the output side of the post-sanitation mixer 110 to pull the water 102 and ozone concentrate 118 through the post-sanitation mixer 110 and out of the post-sanitation nozzle 116.

[0090] In operation, the control system 500 may include a microcontroller 502, a memory 504, a post-sanitation pump 528D / 532C, and a motion sensor 518. The microcontroller 502 is operatively associated with the memory 504, the post-sanitation pump 528D / 532C, and the motion sensor 518. When the motion sensor 518 detects that the floor cleaning machine 202 is moving in a manner that creates a post-sanitation area 204C, the memory 504 is encoded with instructions that, when executed by the microcontroller 502, perform the steps of dispensing a post-sanitation ozone disinfecting solution through the post-sanitation pump 528D / 532C.

[0091] In a second exemplary embodiment, the sanitary pump 528C / 532B may be configured to control the outflow of the sanitary ozone disinfecting solution from the sanitary nozzle 114. The sanitary pump 528C / 532B may be configured to push the water 102 and the ozone concentrate 118 under pressure through the sanitary mixer 108 and out of the sanitary nozzle 114, as shown in FIG. Figure 2As shown, alternatively, the sanitary pump can be configured on the output side of the sanitary mixer 108 to pull the water 102 and ozone concentrate 118 through the sanitary mixer 108 and push it out of the sanitary nozzle 114. In addition, the sanitary pump 528C / 532B can be configured as at least one pump that moves at least one liquid source (water and ozone concentrate), or as a single pump that receives a proportionally mixed sanitary ozone disinfecting solution, or configured in other ways that may be needed and / or desired in a particular embodiment.

[0092] In operation, the control system 500 may include a microcontroller 502, a memory 504, a sanitary pump 528C / 532B, and a motion sensor 518. The microcontroller 502 is operatively associated with the memory 504, the sanitary pump 528C / 532B, and the motion sensor 518. When the motion sensor 518 detects that the floor cleaning machine 202 is moving in a manner that produces a post-sanitation area 204C, the memory 504 is encoded with instructions that, when executed by the microcontroller 502, will perform the steps of dispensing a sanitary ozone disinfecting solution through the sanitary pump 528C / 532B.

[0093] In a third exemplary embodiment, the pre-sanitary pump 528B / 532A may be configured to control the outflow of the pre-sanitary ozone disinfecting solution from the pre-sanitary nozzle 112. The pre-sanitary pump 528B / 532A may be configured to push the water 102 and the ozone concentrate 118 under pressure through the pre-sanitary mixer 106 and out of the pre-sanitary nozzle 112, as shown in FIG. Figure 2 As shown, alternatively, the pre-sanitary pump can be configured on the output side of the pre-sanitary mixer 106 to pull the water 102 and ozone concentrate 118 through the pre-sanitary mixer 106 and out of the pre-sanitary nozzle 112. In addition, the pre-sanitary pump 528B / 532A can be configured as at least one pump that moves at least one liquid source (water and ozone concentrate), or as a single pump that receives a proportionately mixed pre-sanitary ozone disinfecting solution, or configured in other ways as may be needed and / or desired in a particular embodiment.

[0094] In operation, the control system 500 may include a microcontroller 502, a memory 504, a pre-sanitization pump 528B / 532A, and a motion sensor 518. The microcontroller 502 is operatively associated with the memory 504, the pre-sanitization pump 528B / 532A, and the motion sensor 518. When the motion sensor 518 detects that the floor cleaning machine 202 is moving in a manner that creates a post-sanitization area 204C, the memory 504 is encoded with instructions that, when executed by the microcontroller 502, perform the steps of dispensing a pre-sanitization ozone disinfecting solution through the pre-sanitization pump 528B / 532A.

[0095] In another exemplary embodiment, the memory 504 is encoded with instructions that, when executed by the microcontroller 502, prevent the floor cleaning machine 202 from operating if the ozone water generator is not operating properly. In this regard, if for some reason the ozone concentrate 118 is not being produced, the control system 500 can prevent the floor cleaning machine 202 from operating, thereby causing the technician 302 to believe that the floor surface is being disinfected when in fact it is not. Once the ozone water production is restored, the floor cleaning machine 202 can be put back into use via the control system 500.

[0096] refer to Figure 3 ”A” in the figure, shows an example of a control system 500 for an ozone water floor disinfection system 100. In an exemplary embodiment, referenced as “B”, many components of the ozone water floor disinfection system 100 can be integrated together 122 or packaged together to reduce the size, cost and complexity of the system. In this regard, in applications where only a single post-sanitation area treatment and nozzle 116 is used, components such as the ozone water generator 530, the electrochemical generator 516, the ozone concentrate 118 production and storage, and the post-sanitation mixer 110 can be integrated or packaged together 122.

[0097] One advantage in the present invention is that the post-sanitation mixer 110 can proportion the flow of water 102 and ozone concentrate 118, but not mix them. More precisely, a proportioned amount of concentrate flow 126 and a proportioned amount of water flow 126 can be fed into the post-sanitation nozzle 116 and mixed in the air at the exit point of the post-sanitation nozzle 116 or when sprayed. If desired, the post-sanitation and / or mid-sanitation portions of the ozone water floor disinfection system 100 can be configured in a similar manner as may be required and / or desired in a particular embodiment.

[0098] In an exemplary embodiment, the ozone water floor disinfection system 100 for post-sanitation area 204C treatment and nozzle 116 may include a water source 102 and a floor cleaning machine 202. The floor cleaning machine 202 may include a cleaning mechanism 220. The floor cleaning machine 202 is capable of passing through the floor surface 204 into the pre-sanitation area 204A before cleaning, cleaning in the sanitation middle area 204B for a cleaning time (middle-T2) 208 through the cleaning mechanism 220, and moving away from the sanitation middle area 204B to form the post-sanitation area 204C.

[0099] The ozone water floor disinfection system 100 also includes an ozone water generator 530 that receives a portion of the water source 102 and generates the ozone concentrate 118 from the water source 102 .

[0100] The ozone water floor disinfection system 100 further includes a post-sanitation mixer 110. The post-sanitation mixer 110 receives and mixes a portion of the ozone concentrate 118 and a portion of the water source 102 in proportion to form a post-sanitation ozone disinfection solution having a predetermined post-sanitation ozone treatment concentration. The ozone concentration of the post-sanitation ozone disinfection solution is less than the ozone concentration of the ozone concentrate. The predetermined post-sanitation ozone treatment concentration is selected to achieve disinfection of the floor surface 204 within a post-sanitation treatment time (post-T3) 210. The post-sanitation treatment time (post-T3) 210 is greater than the cleaning time (mid-T2) 208.

[0101] The ozone water floor disinfection system 100 further includes a post-sanitation nozzle 116 mounted on the floor cleaning machine 202 near the transition 214 between the mid-sanitation zone 204B and the post-sanitation zone 204C. The post-sanitation nozzle 116 sprays the post-sanitation ozone disinfection solution onto the post-sanitation zone 204C portion of the floor surface 204.

[0102] In operation, cleaning within the mid-sanitation zone 204B removes debris from the floor surface 204, allowing the post-sanitation ozone disinfecting solution sprayed on the post-sanitation zone 204C to contact the floor surface in a manner unimpeded by debris for at least a post-sanitation treatment time (post-T3) 210, which can improve the disinfection of the floor surface without agitation or removal by the floor cleaning machine 202.

[0103] refer to Figure 4 , an example of a conduit housing 128 interconnected with an ozone water generator 530 is shown. In an exemplary embodiment, ozone water production involves electrolysis and ion exchange material 534, which consumes certain components and materials in the process. Therefore, when the ozone water generator 530 and / or electrochemical generator 516 reaches the end of its useful life, the ozone water generator 530 and / or electrochemical generator 516 needs to be replaced. In order to facilitate and speed up the technician 302 to replace the ozone water generator 530 and / or electrochemical generator 516, the conduit housing 128 can be permanently plumbed or otherwise secured in place, and the ozone water generator 530 is screwed 132 onto the conduit housing 128 or removably secured 132 to the conduit housing 128. In this regard, when the ozone water generator 530 and / or the electrochemical generator 516 need to be replaced, the ozone water generator 530 may be easily and quickly removed and replaced with new ozone water generator 530 and electrochemical generator 516 .

[0104] One advantage in the present invention is that once the duct housing 128 is installed and the liquid line is connected, there is no need to remove or disconnect the liquid line to replace the ozone water generator 530. This saves technician 302 time and cost, and reduces the chance of leaks in the system due to having to disconnect / reconnect the liquid delivery line.

[0105] Another advantage in the present invention is how the effluent from assembly unit 128 / 530 is configured. Figure 4 In the example labeled "A", the assembly unit 128 / 530 can be configured to generate ozone concentrate 118, or to generate ozone concentrate 118 in the presence of Figure 4 Mark "B" and Figure 3 As shown, the configuration is to produce an effluent of an ozone concentrate stream 124 and a water stream 126. These streams 124 / 126 may be mixed at the point of departure, or mixed in the air as they are sprayed from one or more nozzles 112 / 114 / 116, as may be required and / or desired in a particular embodiment.

[0106] In an exemplary embodiment, in operation, the duct housing 128 is secured in fluid communication with the water source 102 and the ozone concentrate 118. The electrochemical generator 516 is integrated into the ozone water generator 530. The electrochemical generator 516 includes an ion exchange material 534. The ozone water generator 530 is interchangeable and removably secured to the duct housing 128.

[0107] In an exemplary embodiment, the electrochemical generator 516 can be integrated into the ozone water generator 530. The electrochemical generator 516 includes an ion exchange material 534. The computing device 732 operated by the technician 302 can transmit the test ozone concentration data to the remote data processing resource 702, and receive data corresponding to the remaining service life 826 of the electrochemical generator 516 from the remote data processing resource 702 through the computing device 732.

[0108] refer to Figure 5 , an example of a ratio mixer 106 / 108 / 110 is shown. In an exemplary embodiment, the attached Figure 5 Marked "A", mixing may be performed using a fixed orifice manifold 140 where each orifice 316 / 318 has a different diameter to produce the desired ratio of water 126 and ozone concentrate 124 to produce a single effluent 134 having the desired ozone concentration to flow to the nozzles 112 / 114 / 116.

[0109] Or, attach Figure 5 Mark "B" and reference Figure 7, the fixed hole type manifold 140 may have holes 320 of the same size, and the water 126 and ozone concentrate 124 may be distributed using pumps / valves 528 / 532 under control 414 / 416 to produce the desired ratio of water and ozone concentrate to the nozzles 112 / 114 / 116. The advantage of using pumps 528 / 532 and control system 500 timing 414 / 416 is that the concentration of the ozone water mixture can be dynamically changed. In this regard, as the floor cleaning machine 202 accelerates or decelerates, as well as other reasons and circumstances, the concentration of the ozone water mixture passing through the mixer 106 / 108 / 110 can be changed by adjusting the pulse width timing 414 / 416 of the operating pump 528 / 532. Including stopping the pulse width generation to stop mixing and spraying the ozone water mixture through the nozzle 106 / 108 / 110.

[0110] refer to Figure 6 , an example of a fixed volume inspection chamber 136 is shown. In an exemplary embodiment, the fixed volume inspection chamber 136 receives a continuous flow and maintains a fixed volume portion 222 of the ozone concentrate 118 / 124 or other ozonated fluid. Other ozonated fluids may include a post-sanitation ozone disinfection solution, a mid-sanitation ozone disinfection solution, a pre-sanitation ozone disinfection solution, or other ozonated solutions. The number 218 of fixed volume portions is predetermined based on the test requirements of the ozone concentration test apparatus 602 / 604 / 606. The number 218 can be in the range of 200 milliliters (ml), or other quantities that may be required and / or desired in a particular embodiment.

[0111] In a plurality of exemplary embodiments, at least one fixed volume inspection chamber 136 may be used in one embodiment. In this regard, the fixed volume inspection chamber 136 may be incorporated at a plurality of locations throughout the system 100 so that dissolved ozone concentration may be inspected. These locations may include the ozone concentrate 118 line, the concentrate 124 line, the lines entering or leaving the mixer 106 / 108 / 110, the lines entering the nozzle 112 / 114 / 116, or other locations throughout the system 100 as may be needed and / or desired in a particular embodiment.

[0112] In operation, the ozone concentration test instrument 602 / 604 / 606 may include an ozone concentration test strip 604, an ozone concentration test drop 602, or an ozone concentration test device 606 to test dissolved ozone, or other types and / or kinds of ozone concentration test instruments. The technician 302 may manually use the ozone concentration test instrument 602 / 604 / 606 to insert the ozone concentration test instrument 602 / 604 / 606 into the fixed volume inspection chamber 136 to determine the test ozone concentration of the ozone concentrate 118 / 124, and then read the test ozone concentration in the ozone concentrate.

[0113] For the purpose of disclosure, such ozone concentration test strips 604 may be of the SENSAFE type or brand, the MACHERY-NAGEL type or brand, or other suitable types or brands. Such ozone concentration test drops 602 may be of the CHEMETRICS type or brand, or other suitable types or brands.

[0114] In an exemplary embodiment, when it is necessary to remove the ozone concentrate 118 / 124 in the fixed volume detection chamber 136 , the detection chamber cover 138 can be configured to be opened and closed to meet the needs and / or expectations of a particular embodiment.

[0115] In an illustrative example, the floor cleaning machine 202 is able to enter the pre-sanitation area 204A through the floor surface 204 before cleaning, clean in the sanitation area 204B for a cleaning time (mid-T2) 208 through the cleaning mechanism 220, and move away from the sanitation area 204B to form the post-sanitation area 204C.

[0116] The ozone water generator 530 receives a portion of the water source 102 and generates the ozone concentrate 118 from the water source 102. The ozone water generator 530 includes a conduit housing 128 secured in a fluid communication path with the water source 102, the ozone concentrate 118, and the electrochemical generator 516. The electrochemical generator 516 includes an ion exchange material 534. The ozone water generator 530 is interchangeable and removably secured to the conduit housing 128.

[0117] The fixed volume inspection chamber 136 receives a continuous flow and maintains a fixed volume portion 222 of the ozone concentrate 118 / 124 or the post-sanitation ozone disinfection solution. The number of the fixed volume portion 222 is predetermined based on the test requirements of the ozone concentration test device 602 / 604 / 606.

[0118] In a plurality of exemplary embodiments, at least one fixed volume inspection chamber 136 may be used in one embodiment. In this regard, the fixed volume inspection chamber 136 may be incorporated at a plurality of locations throughout the system 100 so that dissolved ozone concentration may be inspected. These locations may include the ozone concentrate 118 line, the concentrate 124 line, the lines entering or leaving the mixer 106 / 108 / 110, the lines entering the nozzle 112 / 114 / 116, or other locations throughout the system 100 as may be needed and / or desired in a particular embodiment.

[0119] The post-sanitation mixer 110 receives and mixes a portion of the ozone concentrate 118 and a portion of the water source 102 in proportion to form a post-sanitation ozone disinfection solution having a predetermined post-sanitation ozone treatment concentration. The ozone concentration of the post-sanitation ozone disinfection solution is less than the ozone concentration of the ozone concentrate. The predetermined post-sanitation ozone treatment concentration is selected to achieve disinfection of the floor surface 204 within the post-sanitation treatment time (post-T3) 210. The post-sanitation treatment time (post-T3) 210 is greater than the cleaning time (mid-T2) 208.

[0120] The post-sanitation nozzle 116 is mounted on the floor cleaning machine 202 near the transition 214 between the mid-sanitation zone 204B and the post-sanitation zone 204C. The post-sanitation nozzle 116 sprays the post-sanitation ozone disinfecting solution onto the post-sanitation zone 204C portion of the floor surface 204. In operation, cleaning within the mid-sanitation zone 204B removes debris from the floor surface 204, allowing the post-sanitation ozone disinfecting solution sprayed onto the post-sanitation zone 204C to contact the floor surface in a manner unimpeded by debris for a post-sanitation treatment time (post-T3) 210, which can improve disinfection of the floor surface without agitation or removal by the floor cleaning machine 202.

[0121] In operation, the ozone concentration test device 602 / 604 / 606 may include an ozone concentration test strip 604, an ozone concentration test drop 602, or an ozone concentration test device 606 to test dissolved ozone, or other suitable ozone concentration test devices. The technician 302 may manually use the ozone concentration test device 602 / 604 / 606, insert the ozone concentration test device 602 / 604 / 606 into the fixed volume inspection chamber 136 to determine the test ozone concentration of the ozone concentrate or the post-sanitation ozone disinfection solution within the fixed volume inspection chamber 136, and then read the test ozone concentration within the ozone concentrate or the post-sanitation ozone disinfection solution.

[0122] In an exemplary embodiment, reference Fig.10 The computing device 732 operated by the technician 302 can transmit the test ozone concentration data to the remote data processing resource 702, and receive data of the remaining service life 826 of the electrochemical generator 516 corresponding to the service life of multiple ozone water generators from the remote data processing resource 702 through the computing device 732.

[0123] In an exemplary embodiment, in operation, the technician 302 may scan the QR code 836 or other suitable identifier to identify the particular ozone water disinfection system 100 installed in the floor cleaning machine 202 .

[0124] In screenshot 838, the specific ozone water disinfection system 100 identification may be data transmitted to the remote data processing resource 702, and data received back from the remote data processing resource 702 regarding the installation location of the specific ozone water disinfection system 100, detailed information of the specific ozone water disinfection system 100, and other relevant information, as may be needed and / or desired in a particular embodiment.

[0125] In screen shot 840 , technician 302 may enter the test ozone concentration reading just taken and transmit the test ozone concentration reading data to remote data processing resource 702 which may record the test ozone concentration reading.

[0126] In screen shot 842, a plurality of ozone water generator lifespan data is received from a remote data processing resource associated with a particular ozone water disinfection system 100. Such a plurality of ozone water generator lifespan data may include previous test results (time / date, ozone concentration, other data), the technician who took these previous readings, an estimate of remaining lifespan 826, maintenance information, service information, warnings or alarms, and other relevant information as may be required and / or desired in a particular embodiment.

[0127] In an exemplary embodiment, technician 302 may use an ozone sensor that is temporarily or permanently connected to control system 500. In this regard, in operation, control system 500 may include microcontroller 502, memory 504, ozone sensor 522 (temporarily connected to take readings or permanently connected to automatically and / or remotely initiate test ozone readings), and communication interface 508. Microcontroller 502 is operatively associated with memory 504, ozone sensor 522, and communication interface 508.

[0128] The memory 504 has coded instructions which, when executed by the microcontroller 502, perform the steps of recording the test ozone concentration of the ozone concentrate or the post-sanitation ozone disinfection solution via the ozone sensor 522. The test ozone concentration may be data transmitted to the remote data processing resource 702 via the communication interface. The remote data processing resource 702 may confirm the recording of the test results by receiving a plurality of ozone water generator service life data via the communication interface 508. Such a plurality of ozone water generator service life data may include previous test results (time / date, ozone concentration, other data), the technician who took these previous readings, an estimate of the remaining service life 826, maintenance information, service information, warnings or alarms, and other relevant information as may be required and / or desired in a particular embodiment.

[0129] refer to Figure 7, an example of a mixing pulse sequence 400 is shown by transitioning between pump / valve 528 / 532 activation pulses. The mixer pulse sequence 400 can be represented as a square wave 402 / 404, which indicates the period 418 when the electronic pump / valves 528B-D / 532A-C are energized "on" or "open" 410 / 412 to allow water 102 or ozone concentrate 118 to flow, or standby "off" or "closed" to reduce the flow of water 102 or ozone concentrate 118.

[0130] In an exemplary embodiment, the mixing pulse sequence 400 is one or more of the pumps / valves 528B-D / 532A-B being energized and / or otherwise "opened" for a predetermined amount of time to allow the water 102 or ozone concentrate 118 to enter the mixer 106 / 108 / 110. A longer "open" predetermined amount of time allows more of a particular water 102 or ozone concentrate 118 to enter the mixer 106 / 108 / 110. By presetting the amount of time for the water 102 or ozone concentrate 118, the amount of water 102 or ozone concentrate 118 can be mixed to form a pre-sanitation ozone disinfection solution and spray out of the nozzle 112, a mid-sanitation ozone disinfection solution and spray out of the nozzle 114, or a post-sanitation ozone disinfection solution and spray out of the nozzle 116.

[0131] For example, when the pump / valves 528 / 532 provide similar performance, the "opening" time of the electronic pump / valve 528B, 528C or 528D that controls the flow of the water source 102 into the mixer 106 / 108 / 110 is twice that of the electronic pump / valve 532A, 532B or 532C that controls the flow of the ozone concentrate 118 into the mixer 106 / 108 / 110, so as to achieve a ratio of one part ozone concentrate 118 to two parts of the water source 102.

[0132] In an exemplary embodiment, in the attached Figure 7 In reference "A" 414, electronic pump / valve 532A, 532B, or 532C is initially energized to allow source water 102 to enter mixer 106, 108, or 110 for a predetermined period of time 410. Mixer pulse sequence 400 is then initiated by energizing electronic pump / valve 528B, 528C, or 528D. Figure 7 Continuing in label “B” 416 , the ozone concentrate 118 is allowed to enter the mixer chamber 106 , 108 , or 110 for a predetermined period of time 412 .

[0133] The mixer pulse sequence 400 is repeated as needed. Each mixer pulse sequence 400 injects the water source 102 and the ozone concentrate 118 into the mixer 106, 108 or 110 in predetermined amounts for mixing in proportion.

[0134] In an exemplary embodiment, a pressure equalization pause 406 may be inserted between the transition signals 402 / 404. In this regard, each time a pump / valve 528B-D / 532A-C is turned "off" or "closed," a pressure equalization pause 406 occurs before the next pump / valve 528B-D / 532A-C is turned "on" or "opened." The pressure equalization pause 406 allows the coupled piping of the pump / valve 528B-D / 532A-C and the overall pressure of the system to remain stable so that when the next pump / valve 528B-D / 532A-C is turned "on," the pressure is the same as the previous sequence cycle, and in each sequence cycle, the timed sequence of flow rates for the water and ozone concentrate 118 injected into the mixer 106, 108, or 110 is predictable and accurate.

[0135] In an exemplary embodiment, the water pump 528D may be configured to pump the water source 102 into the sanitary post-mixer 110. The concentrate pump 532C is configured to pump the ozone concentrate 118 / 124 into the sanitary post-mixer 110. The control system 500 includes a microcontroller 502, a memory 504, a water pump 528D, and a concentrate pump 532C. The microcontroller 502 is operatively associated with the memory 504, the water pump 528D, and the concentrate pump 532C.

[0136] The memory 504 may encode instructions that, when executed by the microcontroller 502, may perform the step of mixing the post-sanitation ozone disinfection solution at a predetermined post-sanitation ozone treatment concentration by switching between the water pulse 402 width period 410 of the water pump 528D to allow the water source 102 to flow into the post-sanitation mixer 110 during the water pulse 402 width period 410. Also, the concentrate pump 532C may be activated during the concentrate pulse 404 width period 412 to allow the ozone concentrate 118 / 124 to flow into the post-sanitation mixer 110 during the concentrate pulse 404 width period 412. In operation, the water pulse 402 width period 410 and the concentrate pulse 404 width period 412 are selected to produce a post-sanitation ozone disinfection solution at a predetermined post-sanitation ozone treatment concentration.

[0137] In another exemplary embodiment, the memory 504 may encode instructions that, when executed by the microcontroller 502, may perform the step of mixing the sanitary ozone disinfection solution at a predetermined sanitary ozone treatment concentration by switching between the water pulse 402 width period 410 of the water pump 528C to allow the water source 102 to flow into the sanitary mixer 108 during the water pulse 402 width period 410. And, the concentrate pump 532B may be activated during the concentrate pulse 404 width period 412 to allow the ozone concentrate 118 / 124 to flow into the sanitary mixer 108 during the concentrate pulse 404 width period 412. In operation, the water pulse 402 width period 410 and the concentrate pulse 404 width period 412 are selected to produce the sanitary ozone disinfection solution at the predetermined sanitary ozone treatment concentration.

[0138] In an exemplary embodiment, the predetermined sanitary ozone treatment concentration of the sanitary ozone disinfecting solution can be changed based on the speed of the floor cleaning machine 202 along the floor surface 204. In operation, as the mid-T2 208 decreases, the speed of the floor cleaning machine 202 increases, and the predetermined sanitary ozone treatment concentration can be increased, thereby shortening the disinfection time; as the mid-T2 208 increases, the speed of the floor cleaning machine 202 decreases, and the predetermined sanitary ozone treatment concentration can be decreased, thereby extending the disinfection time.

[0139] In another exemplary embodiment, the memory 504 may encode instructions that, when executed by the microcontroller 502, may perform the step of mixing the pre-sanitation ozone disinfection solution at a predetermined pre-sanitation ozone treatment concentration by switching between the water pulse 402 width period 410 of the water pump 528B to allow the water source 102 to flow into the pre-sanitation mixer 106 during the water pulse 402 width period 410. And, the concentrate pump 532A may be activated during the concentrate pulse 404 width period 412 to allow the ozone concentrate 118 / 124 to flow into the pre-sanitation mixer 106 during the concentrate pulse 404 width period 412. In operation, the water pulse 402 width period 410 and the concentrate pulse 404 width period 412 are selected to produce the pre-sanitation ozone disinfection solution at the predetermined pre-sanitation ozone treatment concentration.

[0140] In an exemplary embodiment, the predetermined pre-sanitation ozone concentration of the pre-sanitation ozone disinfecting solution can be changed based on the change in speed of the floor cleaning machine 202 along the floor surface 204. In operation, as the pre-T1 206 decreases, an increase in the speed of the floor cleaning machine 202 can increase the predetermined pre-sanitation ozone concentration, thereby shortening the disinfection time; as the pre-T1 206 increases, a decrease in the speed of the floor cleaning machine 202 can decrease the predetermined pre-sanitation ozone concentration, thereby extending the disinfection time.

[0165] In an exemplary embodiment, the data structure of account record 902 is exemplary and can be appropriately expanded and modified as needed to support the functions and methods of the present invention, and grow and evolve over time to support future functions and methods of the present invention without specific limitations.

[0166] refer to Fig.11 , an example of a plan view 802 is shown for monitoring geo-fenced floor surfaces 804 / 806 / 808 that have been treated with a post-sanitation ozone disinfecting solution. In an exemplary embodiment, when the post-sanitation ozone disinfecting solution has been dispensed into the post-sanitation area 204C, the sanitized post-sanitation area GPS location 804 / 806 / 808, also referred to as the geo-fenced floor surface 804 / 806 / 808, can be recorded via the global positioning system (GPS) 514. The sanitized post-sanitation area GPS location 804 / 806 / 808 data can be transmitted to the remote data processing resource 702 via the communication interface 508. In operation, the portion of the floor surface 204 that has been treated with the post-sanitation ozone disinfecting solution can be remotely monitored.

[0167] Additionally, in an exemplary embodiment, an alarm 812 / 814 may be generated, for example, when the floor surface is not treated with a high enough concentration of ozone to achieve adequate disinfection, an area of ​​the floor surface is missed, or for other reasons that may be necessary and / or desired in a particular instance. Such an alarm 812 / 814 may also be noted on the report 810.

[0168] In another exemplary embodiment, a report 810 may be generated to monitor, track and summarize activities. Such a report 810 may include a plurality of ozone water generator life data, ozone concentration test results, geo-fenced floor surface 804 / 806 / 808 descriptions, locations, disinfection history, and other data that may be needed and / or desired in a particular embodiment.

[0169] refer to Fig.12 , the figure shows an example of the test results of monitoring ozone concentration. Fig.12 In the exemplary embodiment marked “A”, the test ozone concentration of the ozone concentrate 118 / 124 or the post-sanitation ozone disinfectant can be generated by a plurality of ozone concentration testing devices, which include an ozone concentration test strip 604 , an ozone concentration test drop 602 , an ozone concentration test device 606 and an ozone sensor 520 .

[0170] In the attached Fig.12 In reference "B", such ozone concentration test results 816 may be recorded on a remote data processing resource and used to generate a report 818, which may be customized as needed and may be referred to as a plurality of ozone water generator service life data. Such a plurality of ozone water generator service life data may include previous test results (time / date, ozone concentration, other data), the technician who took these previous readings, an estimate of remaining service life 826, maintenance information, service information, warnings or alarms, and other relevant information that may be needed and / or desired in a particular embodiment.

[0171] Reference Fig.12 Label "C", an advantage of the present invention is that by tracking the test results of the change of ozone concentration 822 over time 824, the remaining useful life 826 (also known as the useful life state of the electrochemical generator 516 and / or the ozone water generator 530) can be determined or otherwise predicted. In this regard, the components and materials within the electrochemical generator 516 and / or the ozone water generator 530 degrade over time under normal use. An indicator that changes as the efficiency of the electrochemical generator 516 and / or the water ozone generator 530 decreases can be the amount of ozone produced, so the change in ozone concentration ppm over time can be observed. The present invention can establish a range 828 within which an ozone concentration test result above 832 is considered acceptable and an ozone concentration test result 820 below 834 is considered unacceptable. Appropriate electrochemical generator 516 and / or ozone water generator 530 replacement notification 830 can be sent to the technician 302 and / or the administrator 304. Such a replacement notification may notify the technician 302 and / or the administrator 304 that the electrochemical generator 516 and / or the ozone water generator 530 requires repair or replacement.

[0172] In the event that the ozone concentration test results indicate that the electrochemical generator 516 and / or the ozone water generator 530 are degrading prematurely before their normally expected lifespan, the technician 302 and / or the administrator 304 may be notified to inspect the electrochemical generator 516 and / or the ozone water generator 530 components for water mineral scaling and clean them appropriately. The ability of the present invention to detect cleanable mineral scaling may save the technician 302 and / or the administrator the expense of replacing the electrochemical generator 516 and / or the water ozone generator 530 prematurely.

[0173] In an exemplary embodiment, in operation, the life status of the electrochemical generator 516 and / or the ozone water generator 530 can be displayed on the display 506 / 712B / 712C. The life status is based on a plurality of ozone water generator life data received from the remote data processing resource 702.

[0174] In an exemplary embodiment, the floor cleaning machine 202 may be prevented from operating if the ozone concentration test result 826 is outside of the range 828 and / or below a level deemed unacceptable 834. In other words, if the life span data of the plurality of ozone water generators indicates that the ozone water generator has reached the end of its life span, the floor cleaning machine may be prevented from operating until the electrochemical generator 516 and / or the ozone water generator 530 are repaired or replaced.

[0175] refer to Fig.13 , an example of a method of using an ozone water floor disinfection system 100 is shown. In an exemplary embodiment, the method begins at step 1002 by operating a floor cleaning machine 202 to clean a floor surface 204. The floor cleaning machine 202 includes a cleaning mechanism 220. The method then proceeds to step 1004.

[0176] In step 1004, the floor cleaning machine 202 traverses the floor surface 204, enters the pre-sanitation area 204A before cleaning, cleans in the sanitation area 204B for a cleaning time (mid-T2) through the cleaning mechanism 220, and then leaves the sanitation area 204B to form the post-sanitation area 204C. The method then proceeds to step 1006.

[0177] In step 1006, an ozone concentrate 118 is generated. The ozone water generator 530 receives a portion of the water source 102 and generates the ozone concentrate 118 from the water source 102. The method then proceeds to step 1008.

[0178] In step 1008, a post-sanitation ozone disinfection solution is produced at a predetermined post-sanitation ozone treatment concentration. The post-sanitation mixer 110 receives and mixes a portion of the ozone concentrate 118 and a portion of the water source 102 in proportion to form a post-sanitation ozone disinfection solution having a predetermined post-sanitation ozone treatment concentration, which is less than the ozone concentration of the ozone concentrate 118. The predetermined post-sanitation ozone treatment concentration is selected to achieve sterilization of the floor surface 204 within the post-sanitation treatment time (post-T3) 210. The post-sanitation treatment time (post-T3) 210 is greater than the cleaning time (mid-T2) 208. The method then proceeds to step 1010.

[0179] In step 1010, the post-sanitation area 204C is disinfected. The post-sanitation nozzle 116 is mounted on the floor cleaning machine 202 near the transition 214 between the mid-sanitation area 204B and the post-sanitation area 204C. The post-sanitation nozzle 116 sprays the post-sanitation ozone disinfecting solution onto the post-sanitation area 204C portion of the floor surface 204. In operation, cleaning within the mid-sanitation area 204B removes debris from the floor surface 204, allowing the post-sanitation ozone disinfecting solution sprayed onto the post-sanitation area 204C to contact the floor surface 204 in a manner unimpeded by debris without agitation or removal by the floor cleaning machine 202 for at least a post-sanitation treatment time (post-T3) 210 to improve disinfection of the floor surface 204.

[0181] In step 1102 , if the plurality of ozone water generator lifespan data indicates that the ozone water generator has reached the end of its lifespan, the floor cleaning machine 202 may be prevented from operating.

[0182] In step 1104 , the life status of the electrochemical generator 516 is displayed on the display 506 / 712B / 712C. The life status is based on the plurality of ozone water generator life data received from the remote data processing resource 702 .

[0183] In step 1106, the service life of the ozone water generator 530 can be verified by filling the fixed volume inspection chamber 136 in step 1108. The fixed volume inspection chamber 136 receives a continuous flow and maintains a fixed volume portion 222 of the ozone concentrate 118 / 124 or the post-sanitation ozone disinfectant. The amount of the fixed volume is predetermined by the test requirements of the ozone concentration test device 602 / 604 / 606. The ozone concentration test device 602 / 604 / 606 includes an ozone concentration test strip 604, an ozone concentration test drop 602, an ozone concentration test device 606, or other suitable ozone concentration test devices. The method then proceeds to step 1110.

[0184] In step 1110, the test ozone concentration of the ozone concentrate or post-sanitation ozone disinfection solution is determined by technician 302 manually inserting the ozone concentrator 602 / 604 / 606 into the fixed volume inspection chamber 136 and then reading the test ozone concentration of the ozone concentrate 118 / 124 or post-sanitation ozone disinfection solution therein.

[0186] In step 1112, by the transition between step 1114 of starting the water pulse 402 width period 410 of the water pump 528A, the water source 102 is allowed to flow into the post-sanitation mixer 110 during the water pulse 402 width period 410 to mix the post-sanitation ozone disinfection solution at a predetermined post-sanitation ozone treatment concentration. And, in step 1116, the concentrate pump 532C is started within the concentrate pulse 404 width period 412, thereby allowing the ozone concentrate 118 / 124 to flow into the post-sanitation mixer 110 during the concentrate pulse 404 width period 412. In operation, the water pulse 402 width period 410 and the concentrate pulse 404 width period 412 are selected to produce a post-sanitation ozone disinfection solution at a predetermined post-sanitation ozone treatment concentration.

[0187] In step 1118, when the post-sanitation ozone disinfection solution is dispensed on the post-sanitation area 204C, the disinfected post-sanitation area GPS location is recorded by GPS 514. The method then proceeds to step 1120.

[0188] In step 1120, the disinfected post-sanitation area GPS location is transmitted to the remote data processing resource 702 via the communication interface. In operation, the floor surface 204 that has been treated with the post-sanitation ozone disinfecting solution can be remotely monitored.

[0189] In step 1122, when the motion sensor 518 detects that the floor cleaning machine 202 moves in a manner to form the post-sanitation area 204C, the post-sanitation ozone disinfection solution can be dispensed by the post-sanitation pump 528, such as Figure 3 This is more clearly stated in the marking "B".

[0190] In step 1124, the test ozone concentration of the ozone concentrate or post-sanitation ozone disinfection solution is recorded by the ozone sensor 522. The method then proceeds to step 1126.

[0191] In step 1126 , the test ozone concentration is transmitted to the remote data processing resource 702 via the communication interface 508 . The method then proceeds to step 1128 .

[0192] In step 1128 , a plurality of ozone water generator service life data is received from the remote data processing resource 702 via the communication interface 508 .

[0193] The functions of the present invention can be implemented by software, firmware, hardware or some combination thereof.
