This invention relates to the field of washing and restoration of hard-to-restore items including soiled soft objects, and in particular to a system for monitoring restoration quality to a third party certified standard of soft objects being washed remotely.
There are many examples where articles of clothing and other fabric or otherwise “soft” goods become soiled to the extent that often they are thrown away or used in a soiled condition because the goods cannot conventionally be returned to a clean state. To give one example: firefighters use outer wear which is of a fire-retardant fabric, better described below, which loses some of fire retardant properties as the fabric becomes soiled, notably with organics, smoke, soot, ash, mud, etc. Washing firefighting clothing must be done carefully so as to not disrupt the integrity of seams etc., and to a repeatable standard of cleanliness so that degradation of fire retardant capability is minimized and the fabric's fire retardancy restored to a predetermined and verifiably acceptable and safe level.
Washing such clothing has been accomplished using specialized large-object washing machines such as those provided commercially by Esporta Wash Systems Inc., the applicant herein. Descriptions of such machines are found in U.S. Pat. Nos. 6,374,644 and 6,732,553, which issued on Apr. 23, 2002, and May 11, 2004, respectively, for an Equipment Washer, and which are incorporated by reference herein. Such machines are also described in United States published patent applications 2004/0089030 A1, 2004/0231063 A1, and 2005/0193500 A1 published in May 13, 2004, Nov. 25, 2004 and Sep. 8, 2005, respectively, for an Equipment Washer, and which are incorporated by reference herein. In such machines the objects to be washed may be secured in bins or other means for immobilizing the object in a porous cage. An array of such cages may be formed around the perimeter of a porous rotary drum. The drum is mounted in a water-tight wash housing. Wash fluid; typically a combination of water, detergent, and other ingredients according to present formulas determined in accordance with the objects being washed, is introduced into the wash housing and the drum circulated through the wash fluid whereby hydraulic wash fluid pressure provides the cleaning medium as it is forced through and around the items being cleaned. Pre-set washing, rinsing, spinning, and extraction cycles are employed to remove the soilant from the objects, to then remove the detergents, etc. from the objects, and then to remove the moisture from the objects.
To give another example, restoration of objects salvaged from a fire, such as a residential home fire, or restoration of objects salvaged from flooding of a residence has been limited to date, hampered by lack of a trustworthy standard of cleanliness and a means to accomplish this within a verifiable monitoring system, so that presently often the objects are merely discarded and, to the extent possible, replaced with the proceeds of insurance coverage. Insurance companies thus are motivated to see such replacement more limited than is presently the case, so as to reduce the cost of insurance payouts, and the insured home-owners are motivated to see restoration in cases where replacement of soiled objects cannot be accomplished, for example, in the cases of irreplaceable clothing, or a child's loved stuffed animal toys, or heirlooms—the list goes on, as better described below.
In applicant's view it is preferable for the restoration industry, and in some instances, such as in the firefighting example, also a safety concern, to attempt to standardize standards of cleanliness which can be repeated and, importantly, verified including verified remotely, so as to allow the proliferation of restoration facilities employing the standards.
For items such as protective clothing worn by first responders such as firemen, the level of cleanliness and the manner of washing will affect the safety of first responder. For example, fire retardant clothing provides fire protection to specification when clean, for example when new, but with degraded fire retardancy when soiled. Further, if not washed in a specialized washing machine such the applicant's washing machine mentioned above or for example such as the washing machine described below, then there is a risk of damage to seams and fabric that may degrade the safety of the clothing. It is thus in these cases a matter of safety for the first responder that the operator of the washing machine not cut corners by for example using different wash fluid consumables such as different detergent than those recommended and supplied by the applicant for its washing machines.
In the case of a remotely operated washing facility, it is very difficult to monitor washing operation or to monitor an otherwise remotely located washing machine operator so as to detect when the pre-set and certified washing protocols are not being followed. Again, if the protocols are not followed, then the cleanliness standard may not be met, and thus the insurance company customers and the restoration company customers may be dissatisfied with goods which have been returned to them which have allegedly been cleaned and restored to the desired standard.
One mechanism for avoiding the cutting of costs or the otherwise cutting of corners by operators of remotely located washing facilities is to monitor consumption of the consumables that are to be used in the washing protocols. The operators have to elect which washing recipe they will use for a particular item or set of items. The system described herein records that election, and records when the washing has been done. Each recipe will require a unique set of consumables be used. Tracking the consumables actually used and comparing that to the washing recipes that have been used, and the number of times those washing recipes have been cycled, allows the tallying of use, comparison to on-site inventory of consumables, and thus the detection by the monitoring system of any shortcuts being taken by the operators.
Tracking the consumables that have actually been used has proven to be difficult where tracking relies solely on a fluid metering system, for example working in conjunction with the fluid pumps assigned to each type of fluid consumable (for example detergents, etc.). In applicant's experience, fluid flow and volumetric meters which are available commercially are sufficiently inaccurate at the lower viscosities associated with preferred consumables, that tracking of overall consumption of consumables by an operator using such meters is at present undesirable. Advances in fluid flow rate metering and fluid flow volume metering may allow the future use of such tracking, which may then be monitored by the networked system described herein below.
In the meantime, the system presently knows an initial level of each consumable associated with each machine, knows the wash load/recipe types that a particular washing machine has washed, and the number of those loads. The amount of consumable consumed for each such wash is thus known, as it has been pre-measured for each load type/wash recipe how much consumable is consumed by the operation of a particular pump for its pre-set run-time as prescribed for each wash recipe.
Consumables are shipped from the system administrator to an operator as the consumables are ordered and re-ordered by the operator. The system tracks the consumables for a particular machine, for example using bar coding on the consumables which matches a serial number or other unique identifier to the serial number or unique identifier on the particular washing machine in need of re-supply. For example, the consumables may be shipped in 20 liter pails, or in larger containers. So long as the system knows the volume of each consumable which is shipped to the operator for a particular washing machine and so long as the on-going tally of consumable consumption is maintained and monitored by the system and system administrator, the comparison to usage may also be maintained to thereby assist in verifying that the certified standard of cleanliness is being maintained.
In a preferred embodiment the system is advised of, for example tracks in real time, the arrival of consumables at an operator's premises. Tracking may for example be done by the scanning of barcodes on the containers of consumables for upload to the system by, RFID, by feedback from the shipper, etc., or any combination of these. The object is to seamlessly track the balance between the consumption of consumables for each washing machine, and the timely re-supply of consumables and input of those re-supplied consumables into the washing machines. In this fashion any use of un-authorized consumables, for example a potentially inferior detergent, by an operator will be detected by the system and the particular machine may then be shut-down remotely by the administrator.
The insurance industry is not in, and to applicant's knowledge has no interest in being in, the restoration business. The insurance industry needs to be able to rely, in every instance of restoration, on the standard to which difficult to restore items are being restored. If in extreme circumstances where an insured claimant commences litigation against the insurance company alleging failure of the company to abide by its contractual obligations to cover the claimant's loss, then in such circumstances the insurance company likely must be able to show and prove sufficient due diligence in performance of its obligations. How the insurance company meets its standard of care owed to the claimant, and how it proves that it has met its standard of care required by law, is likely critical if the insurance company is, firstly, to avoid unhappy claimants in the first place; and, secondly, avoid liability in the unavoidable few instances of unhappy insured claimants who either intractably perceive they have been wronged by inadequate restoration when damaged goods should rightfully have been replaced and not restored, or when the insured claimants are fraudulently attempting to collect a windfall from the insurance company based on a specious claim.
In the system described herein, the insurance company meets its standard of care by having pre-approved, or by having a third party pre-approve on its behalf, protocols for restoration of categories of goods to be restored, where the pre-approval is based on independent assessment and verification of the restoration protocols. That is, for example, an independent third party, trusted by the insurance industry, and who is a proven expert in restoration, tests restoration protocols in specific instances, especially where restoration has in the past been difficult or next to impossible, and verifies that the restoration protocols that have been tested, including the process and consumables being used and the corresponding equipment being used, consistently achieve restoration of the specified goods to a high level or otherwise certified level. In the present instance the certified level of cleanliness is known as food-grade-safe.
Restoration to food-grade-safe has proven in applicant's experience to be a safe, high-level standard that can be tested for using an ATP tester which reads so-called Relative Light Units (RLUs). Thus whether restoration to food-grade-safe has been achieved is easily tested and verified using an ATP tester. One such ATP tester is provided by Hygiena/Medical Packaging of Camarillo, Calif. USA. It may to some seem strange to be restoring goods such as textiles in clothing, etc. to a standard literally sufficient to eat off (i.e. food-grade-safe), as in reality, prior to the damage event (example: flooding, sewage leakage, fire, etc.) the insured claimant's goods would not likely have been food-grade-safe. However, the present system described herein provides for attaining food-grade-safe levels of cleanliness and restoration. That standard in applicant's opinion likely exhibits the insurance company's required standard of care in restoration of insured claimant's goods, and may in fact exceed the required standard of care to which an insurance company will be held. Using an ATP tester, in applicant's experience a food-grade-safe level of cleanliness is indicated by a reading of substantially equal to ten RLUs.
So having the insurance industry embrace food-grade-safe as the required standard for restoration, allowing the insurance industry to save costs by restoring goods rather than replacing them as was done in the past, then begs the question of how to implement on a mass market scale, restoration centers which will meet the food-grade-safe standard in every instance of restoration in a virtually fail-safe method. This is a very difficult thing to do, where the number of restoration centers operating daily will be in the hundreds, if not thousands globally. Overseeing such a network so as to substantially guarantee to the insurance industry that in most if not all cases the food-grade-safe standard is being met is not possible without:
In summary, the system for the remote monitoring of cleanliness to a pre-certified standard being achieved by washing machines as described herein may be characterized in one aspect as including:
At least one washing machine wherein each washing machine has a wash processor, and is adapted to wash items according to pre-determined pre-certified recipes using pre-certified consumables, which include pre-certified detergents. The consumables may be provided in removably couplable containers removably couplable to the washing machines. Each wash processor is adapted to communicate over the internet. An administrator processor, remote from the washing machines, adapted to communicate over the internet with each wash processor and to receive information from each wash processor on a repeating, short-time interval. Each said wash processor is adapted to provide to the administrator processor the volumetric consumption of consumables by its corresponding washing machine over successive wash loads according to the recipes. The recipes correspond to characteristics of the wash items in each corresponding wash load and the corresponding nature of the spoilage. The characteristics of the wash items may include what the items are made of; e.g. plastic, fabric, leather, foam/padding or otherwise puffy, etc., or any combination of such materials whether they are specialty wash items such as PPE, and whether the items are heavily, moderately or lightly soiled by various spoilants, for example from provider of insurance over the wash items against damage to the wash items by reason of at least one of the group of spoilants. The certification standard of cleanliness may be advantageously be food-grade-safe, for example defined as a measured RLU reading of substantially ten RLUs.
The administrator processor may use the information from the wash processor for each washing machine to track the consumption of the consumables by each washing machine, to track the available volume of the consumables available at each washing machine, and to compare the consumption of the consumables to the available volume of the consumables at each said washing machine, and to determine therefrom status information including an anticipated re-supply request for consumables from an operator of each washing machine. Upon failure to receive a re-supply request for any one washing machine the administrator or administrator processor may execute and deliver a remote warning, and/or shut-down of the corresponding washing machine.
In one embodiment the information provided to the administrator or administrator processor also includes tracking the re-supply of the re-supply consumables to determine an estimated arrival of the re-supply consumables at each washing machine. The information provided may include for example information updating the available volume of the consumables at each washing machine, and comparing a rate of consumption of the consumables to the available volume of consumables at each washing machine to determine an estimation of when the consumables will be substantially completely consumed by each washing machine and to thereby determine an anticipated re-supply request.
Where the group of wash items being washed includes heavy soiled items, the wash processor may reduce operator control of wash variables controlled by said wash processor for the corresponding washing machine. For example, the wash processor may substantially eliminate operator control of the wash variables for wash items.
In using the system, a method of use includes employing the pre-certified recipes and the pre-certified consumables that have been independently pre-certified by a third party certifier in each washing machine so as to clean and restore the wash items to a pre-determined certification standard of cleanliness approved by the provider of insurance over the wash items against damage to the wash items by reason of at least one of the group of spoilants.
In the following illustrations like reference numerals denote corresponding parts in each view, wherein:
Washing Machine Embodiments
The wash system as described herein is capable of cleaning both standard garments and textiles that conventionally may be cleaned in traditional washing machines, and is also capable of cleaning many other items that would never conventionally be washed in a regular or conventional washing machine. A list of such items, which is not intended to be exhaustive, of soft objects or other items (collectively referred to herein as soft objects or items) that may be washed in accordance with the wash system described herein is listed in Table 1 herein. The objective for washing of soft objects and other items which are not conventionally washed in conventional washing machines is to obtain cleanliness of the items to a certified standard. In the wash system described herein the example is provided of restoring soiled items to a certified standard referred to as “food-grade-safe”.
The wash system restores wash items from all categories of insured losses including what would have been in the past replacement loss claims to soft wash items due to contamination by heavy smoke, soot, mold, blood, as well as category 2 and 3 (grey and black sewage) soiled water. The washing and restoration system as described herein may include processes as described by way of example herein-below, in conjunction with for example the use of the applicant's washing machines, one example of which is also described herein and another incorporated by reference above, where the washing is according to pre-certified washing and restoration protocols which have been certified by third party testing organizations such as Wonder Makers Environmental Inc., located in Kalamazoo, Mo., USA, who provide third party testing for compliance with certification standards.
Other certification testing may be performed by for example Caro Environmental Services of Kelowna, British Columbia, Canada, and by Northwest Labs of Calgary, Alberta, Canada.
In the case of testing done by Wonder Makers Environmental, Inc., an experimental study (“the Wonder Makers study”) was undertaken to compare the effectiveness of a pre-curser wash system to the present wash system with cleaning procedures used by dry cleaning contractors of the Certified Restoration Dry-cleaning Network. The Wonder Makers study was to provide testing of a worst-case scenario where items where intentionally contaminated with smoke, sewage, mold, and blood. The intentionally contaminated representative items were sampled prior to cleaning. The items were them provided as a standard loss to contractors who have specialized in cleaning soft goods for the restoration industry so as to conduct a blind test by the contractors. The clean items were evaluated by a physical assessment and post-cleaning samples.
The physical assessment of the clean items along with laboratory sampling data generated during the study led to the conclusions that: (a) a large percentage of contaminated soft goods can be recovered after fires, floods, and bodily traumas if they are cleaned properly, (b) a substantial percentage of even intentionally difficult contaminated items can be successfully salvaged based on 3-part criteria of the cleaning contractors internal quality assessment standards, a detailed physical review, and sample results, (c) a stringent visual/odours evaluation of the clean items provided a relative accurate indicator of scientifically obtained results, (d) using stringent subjective standards regarding acceptability of stained residues and odour, and notwithstanding the dry-cleaning contractor declared the entire batch of contaminated items to be unsalvageable due to odour or staining, the wash system under study provided greater success in regards to salvageable items as compared to the cleaning processes used by the dry-cleaning contractors. These results were obtained in four different categories; namely, regular fabrics, bulky or quilted, that is, “puffy” materials, leather goods, and materials designated as “dry clean only”. The four forms of contamination used represented the most common kinds of damage to soft goods recovered by restoration contractors; namely, sewage, mold, blood, and smoke.

Basket 20 is fully reinserted into the corresponding cage, hereinafter also referred to as a cage segment 24, in rotary drum 22. In the illustrated example, which is not intended to be limiting, rotary drum 22 has a cross sectional circumference, shown in front elevation view, in the shape of an octagon. The octagonal shape of the circumference is due to the triangular shaped cross section of each cage segment 24. Rotary drum 22 provides eight triangular compartments; that is, eight cage segments 24 into which corresponding baskets 20 are snugly received in their sliding engagement therein.

Advantageously, a pin and receiver or other positive locking mechanism is provided for each cage door 14 on each cage segment 24 of rotary drum 22 so as to prevent inadvertent opening of a cage door 24 during rotation of rotary drum 22, for example during wash, rinse, spin or extract cycles. Such a positive locking mechanism is provided so that an operator of machine 10, once the cage door 14 exposed in opening has been shut, may positively lock that cage door 14 in its closed position. Locking pins 14a are illustrated diagrammatically by way of example in

It is also understood, although not shown, that various replaceable containers of detergent and other wash fluids, for example, fragrances, sanitizers, etc. would ordinarily be located adjacent washing machine 10, for example to the rear of the machine, or in some embodiments located within washing machine 10 so as to be easily replaced as the fluids are consumed from within the containers. The fluid containers may advantageously be removably mounted to for example, corresponding hoses having corresponding pumps (not shown). The pumps pump the various fluids under pressure into wash housing 30. The fluid containers are removably coupled to their corresponding hoses or other fluid conduits and are thus removably coupled so as to be in fluid communication with the washing machine, and in particular with rotary drum 22.
One of the desired cleaning mechanisms provided by the wash system is that the items 16 within baskets 20 within the porous cage segments 24 of rotary drum 22 are impinged by the various wash fluids which are injected or sprayed under pressure into rotary drum 22. The various wash fluids impinge items 16 through various and numerous apertures in the cage segments 24 (wherein cage segments 24 and rotary drum 22 may for example be a very sturdy segmented wire cage), and through apertures 20a in baskets 20, so as to permeate the bulk of the various soft or hard wash items 16 to thereby more effectively clean the wash items.
In some instances hard wash items may themselves contain soft items requiring cleaning. For example, sports helmets are rigid on the outside and contain soft or spongy materials on the inside, and it is often the case that it is the interior soft and spongy materials that require cleaning, in many cases more than the rigid materials on the exterior. A balance must be achieved between, firstly, vigorously circulating the soft materials of items 16 through the wash fluids as they are injected or sprayed in wash housing 30 or as the wash fluids are turbulently tumbling in wash housing 30 as rotary drum 22 is rotated within wash housing 30, and secondly, inhibiting damage to the rigid or hard items or components of the items.
With the correct sizing of baskets 20 and corresponding cage segments 24, or for example by the use of inserts such as mesh holders or bags on folding or rigid frames (not shown), wash, items 16 may be held sufficiently snuggly and separated within their corresponding basket 20 so as to not only be cleaned but also to inhibit damage to the various items 16 caused by the items moving around within basket 20. Advantageously basket 20 may be constructed of soft or compliant plastics so as to minimize damage to items 16. In some cases, item 16 may have further containment within baskets 20, for example porous bags, etc. (not shown) to assist in the holding of the various items 16 within their corresponding basket 20.
In
In one preferred embodiment, not intended to be limiting, the washing machine motor and corresponding transmission, for example a pulley system, for rotationally driving drive axle 26 is adapted to provide not only relatively slow rotational agitation cycles but also high rate of rotation fluid extraction cycles. Slow rotational agitation cycles may be provided for example when each cage segment 24 is to be rotated through washing fluid 32 which has been pumped into wash housing 30, during which the combined fluid resistance and the weight of the tumbling fluids passing through the cages segments 24, baskets 20, and items 16 within wash housing 30, combined with the wet weight of items 16 may put significant loading and strain on the drive system including the motor and transmission. In the illustrated embodiment, which is not intended to be limiting, the total dry weight of items 16 held in all cage segments 24 may, collectively, be in the order of 120 pounds. Advantageously, during loading of items 16, their dry weight is somewhat evenly distributed around rotary drum 22.
During wash fluid extraction and spin cycles, in order to obtain sufficient centrifugal separation of wash and rinse fluids from items 16, which may be highly retentive of fluid, rotary drum 22 may have to be rotated on drive axle 26 at high rotational speeds, for example at speeds exceeding 200 rpm, so as to generate for example centrifugal forces, measured as multiples of the force of gravity (g's), in the order of 50-70 g's acting on items 16. The motor loading, and strain on the transmission, at these speeds may, consequently, again be high. At such high rotational speeds, and creating such high centrifugal g forces, it has been found that the framework supporting wash housing 30 etc. must be significantly robust.

Example of Data Flow within Washing System
A diagrammatic representation of the data flow in one embodiment of the washing system is illustrated in
Each washing machine 10 at each remote location 100 has a data connection between the remote location 100 and a system administrator 102 and/or corresponding administrator processor (collectively system administrator 102) which may be located at great distance from any one of remote locations 100. Some form of contractual arrangement may exist between the system administrator 102, or the corporate entity for whom the system administrator 102 works, and the Customers or operators at remote locations 100. Under such contractual arrangement the Customers or operators, or their corporate legal entities, are bound to follow the protocols set out below by way of example, and thus provide restoration of items 16 to a certified standard such as the food-grade-safe standard or such other standard as may be required by the insurance industry from to time-to-time.
In
The dashed data flow lines 104, as set out in Table 2, denotes a two way communication link that allows the administrator 102 to remotely monitor machine activity of machines 10 at remote locations 100, perform machine diagnostics remotely, install program updates remotely, and, as necessary, remotely turn washing machine 10 on or off as better described below.
The solid data flow lines 106, as set out in Table 2, denotes a two way communication link between the system administrator 102 or its employees, for example machine technicians and cleaning technicians, and the remote Customer or operator at remote locations 100, using for example instant messaging, voice calls, video calls, etc.
The hash mark data flow lines 108, as set out in Table 2, denotes a two way communication link that allows the Customer at remote location 100 to view and report specific wash system machine analytics provided by the administrator 102, for example, the number of wash loads, the detergent usage, the cost to the Customer per wash loads, the number of washes etc. Data flow 108 allows the Customer to review and report the Customer's machine analytics from any internet browser through a secure administrator machine web User Interface (UI) 110.
The data flow lines 112, which consist of a row of “+” symbols as set out in Table 2, denote a one way communication that sends machine analytic data, (for example date, time, wash load number, detergents usage (for example, in millilitres), water temperature, water usage, etc. by email (for example in “csv” file format) to the administrator email server 128 which is then parsed and deposited into the administrator data base 114.
The data flow lines 116, which consist of a row of dots as set out in Table 2, denotes a two way communication link that allows an administrator employee to view, add, edit, delete administrator wash system machines analytics, for example, the number of wash loads, the detergent usage, the cost per wash load, the number of washes etc. from any internet browser through a secure machine web user interface 110.
The data flow lines 118, which consist of a row of dashes alternating with “x's” as set out in Table 2, denotes a two way communication link that allows the administrator 102 to remotely view, edit, add, delete, and report the analytic data generated by each Customer wash system at remote location 100 and also to view, edit, add and delete the content (for example the frequently ask questions (FAQ), the training videos, the maintenance videos, etc.) provided by the administrator 102 and access by the Customers at remote locations 100 though either the machine tablet 120 or any browser enabled device.
The data flow line 122, which is denoted by a corrugated line as set out in Table 2, denotes a two way communication that provides touch screen operated instructions from the human machine interface (HMI) 124 to the wash processor including the programmable logic controller (PLC) 126 which operates the components of the washing machine 10 (for example, to run or stop the washing machine motor, to open or close various drain valves, to open or close pumps, etc.).
Again with reference to
HMI software 214a, PLC software 126a and E-catcher software 134 are enabled on PC 136 and interface with Talk2M server 138 via internet 130 and firewall 140, with the exception that data flow 116 bypasses Talk2M server 138.
The Customers or operators at remote locations 100 may access machine web user interface 110 using any internet browser 142 so as to thereby interface with the administrator web server 132 via machine web user interface 110 and firewall 140. At remote locations 100, data flows 106, 104, and 118 exchange data between tablet 120, used by the operator to control, in one preferred embodiment, washing machine 10 via WIFI router 144, and the “EWON” virtual private network router 146.
In one embodiment of the present system the above network may be employed, modified as need be and as would be known to one skilled in the art, to help avoid the cutting of costs or the otherwise cutting of corners by operators of the remotely located washing facilities by monitoring consumption of the consumables that are to be used in the washing protocols. The operators have to elect which washing recipe they will use for a particular item or set of items. The system records that election, and records when the washing has been done. Each recipe requires a unique set of consumables be used. Tracking by the administrator of the consumables actually used and comparing that to the washing recipes that have been used, and the number of times those washing recipes have been cycled, allows the tallying of use, comparison to on-site inventory of consumables, and thus the detection by the administrator of shortcuts being taken by the operators.
Tracking the consumables that have actually been used has proven to be difficult where tracking relies solely on a fluid metering system, for example working in conjunction with the fluid pumps assigned to each type of fluid consumable (for example detergents, etc.). In applicant's experience, fluid flow and volumetric meters which are available commercially are sufficiently inaccurate at the lower viscosities associated with preferred consumables, that tracking of overall consumption of consumables by an operator using such meters is at present undesirable such meters may however be employed as the technology improves. Thus, advances in fluid flow rate metering and fluid flow volume metering may allow the future use of such tracking, which may then be monitored by the networked system.
In the meantime, presently the administrator in this embodiment of the system knows an initial level of each consumable associated with each machine, knows the wash load/recipe types that a particular washing machine has washed, and the number of those loads. The amount of consumable consumed for each such wash is thus known, as it has been pre-measured for each load type/wash recipe how much consumable is consumed by the operation of a particular pump for its pre-set run-time as prescribed for each wash recipe.
Consumables are shipped directly or indirectly from the system administrator to an operator as the consumables are ordered and re-ordered by the operator. The system tracks the consumables for a particular machine, for example using bar coding on the consumables which matches a serial number or other unique identifier to the serial number or unique identifier on the particular washing machine in need of re-supply. For example, the consumables may be shipped in 20 liter pails, or in larger containers. So long as the system knows the volume of each consumable which is shipped to the operator for a particular washing machine and so long as the on-going tally of consumable consumption is maintained and monitored by the system and system administrator, the comparison to usage may also be maintained to thereby assist in verifying that the certified standard of cleanliness is being maintained.
In a preferred embodiment the system is advised of, for example tracks in real time or other more intermittent intervals, but advantageously no longer than short-intervals such as several times per day for example, the arrival of consumables at an operator's premises. Tracking may for example be done by the scanning of barcodes on the containers of consumables for upload to the system by, RFID, by feedback from the shipper, etc., or any combination of these. The object is to more or less seamlessly track the balance between the consumption of consumables for each washing machine, and the timely re-supply of consumables and input of those re-supplied consumables into the washing machines. In this fashion any use of un-authorized consumables, for example a potentially inferior detergent, by an operator will be detected by the administrator and the particular offending machine may then be shut-down remotely by the administrator.
Washing Machine Operator Control
Once the system is initialized, the “enter” screen 212, as better seen in
From the home screen 214, the operator may select the “run” button which then takes the operator to wash type screen 218, better seen in
Using the “back” button on wash type screen 218, the operator is returned to home screen 214. If the operator selects the “alarms” button on the home screen the operator is taken to the alarms screen 220, better seen in
As also indicated in
If the operator returns to home screen 214, or had remained at home screen 214, and had selected the “run” button, then the operator is taken to the “control panel” screen 228, better seen in
In the instance that the operator had selected the machine information screen 230, the operator may then select one of four buttons; namely the “detergent inventory” button, the “hour meter” button, the “water meter” button, or the “wash cycle counter” button. If the operator selects the “hour meter” button, then the operator is taken to the hour meter screen 236 better seen in
When the operator is in the detergent inventory screen 242, the operator is presented with a stacked array of “reset” buttons, in the illustrated embodiment which is not intending to be limiting, six reset buttons corresponding to six displayed “Stages”. Each reset button, labelled “reset inventory” in screen 242 takes the operator to a corresponding “set pail volume” screen 244 better seen in
Returning now to the instance where the operator has selected the maintenance screen 232 from the control panel screen 228, the operator in maintenance screen 232 has a selection of six buttons to choose from; namely, a “water valves”, a “drain valve”, a “brake” button, a “pump calibrate” button, a “detergent flush” button and a “water level drain check” button. The “brake” button engages the brake which arrests rotation of rotary drum 22. The detergent “flush” button flushes the detergent from the system. The “water valves” button takes the operator to the water valve test screen 246, better seen in
In the instance that the operator when at the control panel screen 228, selects the “configuration” button, the operator is take to configuration screen 234 and presented with six buttons to select from; namely, a “set” button, a “language” button, a “screen configure” button, a “time set-up” button, a “units” button and a “machine serial” button. If the operator selects the “set point” button, then the operator is taken to the set point screen 254, better seen in
If from the home screen 214 the operator has selected the “run” button, the operator is taken to wash type screen 218, better seen in
If the operator selects the “leather” button, the operator is taken to the leather contamination screen 268, better seen in
In the event that the operator selects the “light”, “medium”, or “heavy” buttons in the wash type screen 218 then the operator is taken to the wash temperature screen 270 and presented with the choice of wash fluid temperatures by use of corresponding “cool”, “warm” or “hot” buttons, as better seen in
Once the operator has selected the finishing agent (or no finishing agent), the operator is taken to the machine load screen 276, which is also the machine load screen that the operator is taken to upon selection of the leather contamination in leather contamination screen 268, as better seen in
In the wash cycle summary screen the operator is presented with a summary of the operator selections in teems of wash type, load size, wash temperature, finishing agent, and spin speeds. The selections made by the operator are matched by the wash processor to a corresponding recipe, for example as described below, and from that recipe the volume of the various consumables are determined and multiplied by the presently stored cost of each consumables, and those costs amount are summed and a total cost for the selected wash is presented in wash cycle summary screen 280 in the “to run” field. The predetermined run times for the various cycles associated with the selected wash are then also summed and the results in minutes and seconds are displayed adjacent to the cost field in the wash cycle summary screen. The operator is then prompted to initiate the selected wash cycle by a prominent “run” button located on the screen adjacent to the wash cycle summary information.
If in the wash type screen 218 the operator has selected the “PPE” button, that is, the button associated with the washing Personal Protective Equipment, then the operator is taken to the PPE wash screen 282, better seen in
Once the operator selects the appropriate type of PPE to be washed by selecting the corresponding button on the PPE wash screen 228, the operator is taken to the pre-rinse screen 284, better seen in
In the event that the operator has selected the “extra-heavy” or “sewage” buttons in wash type screen 218 then the operator is taken to the sanitize screen 286, better seen in
Once the operator is satisfied with the wash cycle that has been selected as displayed in wash cycle summary screen 280, and the operator then selects the “run” button on wash cycle summary screen 280, the operator is taken through a sequence of five “step” screens, namely; the water-in screen 288, better seen in
Each of the five step screens 288, 290, 292, 294, and 296 also have a “+” button in the lower right-hand corner which, when selected, takes the operator to a corresponding “details” screen as seen in the corresponding “water-in” details screen 288a as seen in
Thus in operation, once an operator has selected the “run” button in the wash cycle summary screen 280, the selected displayed wash will cycle through the five step screens, showing the operation of the wash during each step in the corresponding step screen. Each step screen; whether it be the water step, the detergent step, the rotation step, the drain step, or the extract step, shows which steps is presently engaged and how far the machine is presently into that particular step. During the display of each of sequential steps screens, the operator may select to look at the corresponding details screen. Thus for example while the water-in screen 288 is displayed, the operator is told the length of time for that particular step, the elapsed time of the execution of that step and the predicted total time to finish all of the steps. If the operator selects the water-in detail screen 288a then, for example, the water temperature, both the set point desired for that step, and the current water temperature is displayed, and the water level, including the set point for that step, and the current water level is also displayed. Whether the water-in is hot or cold can also be displayed. By way of further example, if the operator selects the detergent details screen 290a, the following information may be displayed; the water flush time, the volume of detergent required the current volume of detergent which has been used during the present wash step, and the elapsed time of the detergent step. Also which may advantageously be displayed is a graphic representation as to which of the pumps are engaged. In the illustrated example six pumps are shown and one is indicated as activated (corresponding to which of the six Stages in the recipe is being pumped). If the pumps are being flushed then that status may be provided also.
In the rotation details screen 292a, the speed of rotation of rotary drum 22 within wash housing 30 is displayed, for example in the revolutions per minute (RPM). Thus, depending on the type of wash which was selected by the operator, the desired wash speed set point is displayed, the current rotation speed is displayed, the rotation time is displayed, and the wait times may also be displayed. Further, indicators may be provided to tell the operators whether the rotation is presently clockwise or counter-clockwise, as the cage may be rotate back and forth both clockwise and counter-clockwise to provide efficient agitation of items 16 through the wash fluids 32 contained in wash housing 30.
In the drain details screen 294a, the operator may be provided with the drain time's set point or estimated drain times, and also the presently elapsed time during the drain step. The operator may also be provided with an indication whether the drain valve is presently open or closed. In the extract details screen 296a, the operator may be provided the presently requested water extract RPM for rotation of rotary drum 22, the currently obtained RPM of the rotary drum and the final RPM speed of the rotary drum, which in the example illustrated, maybe as high as 209 RPM for final water extraction from item 16 when they are subjected to very high g-loadings within baskets 20. Again an indicator may be provided it to the operator as to whether the drain valve is open or not.
Once the five steps have been completed, a sequence of views entitled “wash-complete” are presented to the operator. In particular, by way of example, a wash complete first screen 300a better seen in
Standard and PPE Wash Recipes
Table 5 lists thirteen washing recipes which are provided herein by way of example for use within the present system. Each recipe listed in Table 5 is set out in detail in corresponding Tables 5.01-5.13. Each of Tables 5.01-5.13 provide numbered steps which corresponds to a described action, a recipe group, a list of detailed headings, the corresponding variable amounts, and finally the amount of the anticipated time for that step. In the action column of each table the description of the action may be for example “water-in”, which comprises the step of filling the wash housing to its predetermined level. “Classic Stage 1” refers to a first detergent which would be located in a first pail or other container associated with a first pump and flow lines into the wash housing. “Classic Stage 2”, which may be a penetrator detergent, is located in a second pail or container associated with a second pump and its flow lines into the wash housing. A “Classic Stage 3” may be a force additive detergent located in a third pail or container having a third associated pump for pumping the third Stage detergent via dedicated flow lines into the wash housing. The described action in the action column may also include “rotation” for the relatively slow rotation of the rotary drum through the wash fluids according to the details listed in the detail column. The action in the action column may be “drained” for the draining of the wash fluids from the wash housing. A first wash and drain cycle may be followed by a rinse cycle wherein again the action column will include a water-in step, then, as called for, a softener or fragrance finishing agent, a rotation step, and then an extraction step. The extraction steps may include a first, medium speed rotational extraction, and a second, high-speed rotational extraction of the remaining water in items 16 held within baskets 20 within the rotary drum.
Where reference is made to Stage 4, in one embodiment that is a reference to fragrance fluids contained in a pail or other container which has its own associated pump and flow lines into the wash housing. Similarly Stage 5 may be softener fluids contained in a further pail or container and having an associated pump and flow lines into the wash housing. Stage 6 may refer to PPE cleaner contained in its own pail or other container and having its own associated pump and flow lines into the wash housing.
In certain recipes the variable amount may be chosen by the operator, for example in the water-in steps in the light, medium and heavy recipes (Tables 5.01-5.03 respectively). Where a variable may be varied by an operator the symbol “VV” is found in the variable column. In more control critical recipes such as the sewage recipe of Table 5.05, less control is given to the operator. For example, in the sewage recipe, the water in temperature is pre-set to 35° C. in step one, and 200° C. in Step 14.
Where the variable settings are not to be tampered with by the operator, for example the amounts of Stage 1 and 2, and in applicable instances, Stage 3 detergents, the volumes are pre-set as for example in the heavy recipe of Table 5.03. In the heavy recipe the Stage 1 detergent has a volume of 340 ml, the Stage 2 detergent has a volume of 480 ml and the Stage 3 detergent has a volume of 390 ml. As set out in the tables most of the variables are pre-set so as to meet the cleaning certification required to consistently obtain the food-grade-safe standard of cleanliness. Thus for example in the leathers recipe of Tables 5.06 and 5.07 the final extract speed which is operator variable in light washing is predetermined and pre-set at 196 rpm so as to generate very high g-loadings on items 16 held in the rotary drum. The amount of time for each step is also controlled so, that for example the high final extraction speed of 196 rpm called for in the leathers sewage recipe is only 10 minutes for the entire extraction step, whereas the extraction step, again at 196 rpm for the final extraction speed lasts 25 minutes for water extraction from a firefighter thermal liner moisture barrier as set out in Table 5.08.
