    Field of the Invention
    [001] The invention generally relates to an automated cleaning method and apparatus, and more particularly to an automated cleaning method and apparatus for controlling the direct application of concentrated product on an article to be cleaned based on the type of e / or dirt in the article. Fundamentals of Related Technique
    [002] In a traditional cleaning device or method, the article and dirt, despite the differences in the articles being cleaned and the type of dirt, are cleaned with the same chemicals, often present in the bulky cleaning liquid. For example, depending on the article to be cleaned, various chemicals are used that are either not needed, caustic for the type of article, or fail to provide the best final result. In a typical dishwasher cycle, water fills the dishwasher's volume washing tank and cleaning chemicals and detergents are added to the water in the volume washing tank. The water is pumped by a washing pump to the rotating spray arms. The sprayed water washes the dishes and returns to the volume water tank, where it is recycled after being filtered. The dishes are then rinsed with clean water, sanitized and dried. Some bulk water tanks are manually drained and replenished after multiple washes, while some are automatically drained after each or more cycles.
    [003] It is, therefore, desirable to provide a cleaning method and apparatus that, before a product is distributed for cleaning the article, the type of article and / or type of dirt is identified. The products to be distributed are identified along with a preferred product distribution sequence based on the type of article and / or dirt.
    [004] It is additionally desirable to provide an automated cleaning method and apparatus that, in addition to the recirculation of the volume solution, has the ability to apply the concentrated product directly to the article being cleaned; product selection is based on the type of article and / or type of dirt on the article. Summary of the Invention
    [005] According to the present invention, the problems mentioned above as well as others are solved by providing an automated cleaning method and apparatus. In one embodiment, the invention is an automated cleaning method. The method includes the steps of supplying a cleaning device, determining the concentrated products to distribute based on the type of article to be cleaned, the direct application of the products concentrated on the article and cleaning the article with the applied products. The method also includes identifying the type of article and controlling the type of concentrated products to be distributed based on the type of article. The distribution sequence for each concentrated product is also controlled based on the identification of the article and / or type of dirt.
    [006] In another embodiment, the invention is an automated cleaning method for cleaning articles. The method includes providing a cleaning apparatus for cleaning articles, determining a concentrated product for distribution to articles based on the type of article, direct application of the product to the article, and cleaning the article with the applied product. The method also includes providing a cleaning apparatus to clean dirty articles, determining a concentrated product for distribution to articles based on the type of dirt, direct application of the product to the dirty part of the articles, and cleaning the article's dirt with the applied product. In a preferred form, the method also includes controlling the location of product application on an article surface based on the type of article and / or dirt.
    [007] In another embodiment, the invention is an automated cleaning device. The apparatus includes one or more product distribution points providing a direct application of a product concentrated on an article to be cleaned and a control device providing a product distribution signal to distribute the product at product distribution points based on a type of article to be cleaned. In a preferred form, the automated cleaning apparatus includes a product distribution sequence for controlling a type of concentrated product distributed at the product distribution points based on the type of article and / or dirt.

Detailed Description of Preferred Modalities
    [008] The present invention provides an automated cleaning method and apparatus for cleaning articles according to the particular type of article type and / or dirt in the article.
    [009] With reference to figure 1, the components of an automated cleaning apparatus 20 are illustrated according to an illustrative embodiment of the present invention. The cleaning apparatus 20 includes a shelf 22 on which the articles to be washed are located. The cleaning appliance 20 can be a commercial recirculated washing dishwasher with a standard dish rack, although other cleaning appliances can be employed, including without limitation the cleaning appliances for cleaning articles where direct application of the cleaning product or concentrated product to the article provide the benefits of existing systems.
    [0010] The cleaning apparatus 20 includes a cabinet body 24 housing the shelf 22. A washing tank 26 is included to generally maintain the same amount of volume washing liquids used in the cleaning process. A pump is connected in fluid communication with the wash tank 26 to increase the pressure of the liquid in the wash tank 26 and direct it to the wash spray arms 30 and 32. The wash spray arms 30 and 32 include nozzles for directing the liquid to articles 34 in rack 36. In addition to the lower and upper spray arm 30 and 32, the cleaning apparatus 20 may include a lower rinse spray arm 38 and an upper rinse spray arm 40 to direct rinse fluids to articles 34 in rack 36. The spray pressure can be controlled by controlling the pump action or using a piping valve (not shown). For example, when washing a lighter plastic article, a lower spray pressure from the washing arm or lower rinse may be desirable so as not to disorient the article within the cleaning apparatus 20.
    [0011] An identifier (not shown) is positioned in rack 36. This will allow identification of the types of items 34 loaded in rack 36. The methods and systems for recognizing the identifier are described in a patent of the same property No. 7,437 .213 of Batcher, issued on October 15, 2002, which is incorporated by reference here in its entirety. The identifier is preferably pre-programmed with unique identification information, such as an identifier value indicating the type of rack 36 being used, that is, a rack designated for glasses, plates, glasses, pots and pans, etc. The identification of articles can be done, for example, by using racks designed specifically for articles 35; by the use of optical recognition; by the use of bar codes; the color of rack 36; by attaching a transponder to articles 34 themselves; or by using a proximity sensor. Examples of various types of articles 34 include, without limitation, glassware, pots and pans, plates, cups, dishes, coffee cups, aluminum-coated pots, and any other type of item associated with a common cleaning sequence, such as those that can be cleaned using the apparatus 20 of the present invention.
    [0012] The cleaning apparatus 20 may also include a user interface, such as a Graphical User Interface (GUI) for an operator or user to manually register the type of items 34 loaded in rack 36, as illustrated in step 70 on figure 4. Using the automated article identification method and the system described above and incorporated by reference here, the control device upon detection of the identifier associated with rack 36 indicating the type of articles 34 to be cleaned, can be received on user interface 42 to indicate to the operator or user the type of item that the cleaning device 20 has identified in rack 36.
    [0013] Cleaning apparatus 20 also includes a chemical distributor 46 adapted to receive chemical distribution instructions from controller 44. Distributor 46 may include any number of cleaning products or concentrated products, such as cleaning chemicals for dispensing to the cleaning apparatus 20. The dispenser 46 includes one or more dispensing pumps. For example, depending on the number of chemicals being dispensed, the number of dispensing pumps can be changed accordingly. In an illustrative embodiment of the present invention, dispenser 46 includes three or more, or six or less, delivery pumps. Additional timing pumps are possible. The term pump can be a vacuum cleaner or other means for distributing a chemical to be sprayed on the dirty surface of the articles loaded in rack 36. The dispenser 46 can be connected in fluid communication with the spray points inside the body of the appliance. cleaning 20. In one aspect of the present invention, the cleaning apparatus 20 includes one or more lower spray points 48 and / or one or more upper spray points 50. Upper and lower spray points 48 and 50 include nozzles with a opening directed towards rack 36 and articles 34 in rack 36. Depending on the type of article and / or dirt in the article, controller 44 provides a dispensing instruction for distributor 46 to spray the product, such as chemicals, from the top or bottom or both spray points inside the cleaning device 20. Spray points are usually determined based on the type of article and / or the type of dirt in the article being cleaned. For cups, the product is sprayed directly onto the cups loaded in the rack 35 from lower spray points 48 to apply the product to the dirty inner surface of the cups. For example, to effectively remove tea and coffee stains from coffee cups, the concentrated product is distributed from lower spray points as cups are traditionally loaded upside down on rack 36. Similarly, for the dishes, the product is sprayed from the upper spray points 50 in order to be applied directly to the surface of the plate that needs to be cleaned. Since the plates are generally face up when loaded in rack 36, application of product from the upper spray points 50 provides the most efficient and effective use of the product being distributed directly on the plates. Conversely, the application of concentrated product from lower spray points 48 to the back of the plates is wasteful. The product can be dispensed from both the lower spray point 48 and the upper spray points 50 simultaneously if necessary for articles that are dirty on both the upper and lower surfaces. In another aspect of the present invention, the concentrated chemical is applied to articles 34 using the lower rinse spray arm 38 and / or the upper rinse spray arm 40 based on the concentrated product distribution cycle, washing and rinsing cycle. In this modality, the dispenser 46 is connected in fluid communication with the lower rinse spray arm 38 and the upper rinse spray arm 40 for directing the concentrated product from the dispenser to articles 34 in rack 36. Thus, the cleaning apparatus 20 can be configured without the upper and lower spray points 48 and 50 shown in figure 2 when the dispenser applies the concentrated product to articles 34 using the lower rinse spray arm 38 and the upper rinse spray arm 40. In this way, cleaning products such as chemicals are applied only generally to the dirty surface of the article being cleaned rather than to all surfaces of the article. Although the cleaning apparatus 20 illustrates both the upper and lower spray points 48 and 50, the present invention contemplates that additional spray points may be included depending on the type of article being cleaned. For example, spray points can be included at side or corner locations within the cabinet body of the cleaning apparatus 20 to provide the best angle for spraying and applying cleaning products or concentrated product directly to the dirty surface of articles 34.
    [0014] The controller 44 of the present invention is programmed to spray the concentrated product, the washing liquid and the rinsing liquid from the upper and / or lower spray points 48 and 50 based on at least one or more of the following factors, including product distribution sequence, type of article, type of dirt, water condition, type of concentrated product, washing cycle, rinse cycle, concentration of recirculated washing detergent, etc.
    [0015] The present invention contemplates that the cleaning device 20 can include any number of product distribution strings stored in a data storage device (not shown) in control and communication with the controller 44. The data storage device (not shown) can be used to store a set of predetermined chemical combinations and cycle sequences and durations specifying the cleaning chemicals to be used according to the various types of articles and / or type of dirt. Figure 2 illustrates an illustrative table of the cleaning parameters for one or more distribution sequences for the illustrative embodiments of the present invention.
    [0016] The controller 44 in combination with the data storage device (not shown) can be considered a memory storage unit that includes a set for identifying information and a corresponding set of custom processing parameters created according to the type of article and / or dirt in the article to be cleaned. Such information associated with each type of article and / or type of dirt in the article to be cleaned may include corresponding chemical types to be used, the quantities of each chemical to be used, the distribution sequence for each of the chemicals to be cleaned. cycle length for each chemical, cycle length and pressure for the recirculated wash cycle, etc. In each case where the chemical is applied to the article and / or dirt in the article, the chemical is applied directly to the dirty surface of the article being cleaned.
    [0017] As illustrated in figure 3, once the article and / or type of dirt has been identified (see step 50) using the methods described above and incorporated by reference to US patent No. 7,437,213, issued in 4 As of October 2008, controller 44 determines the appropriate concentrated product to be distributed to the dirty surface of the article to be cleaned according to step 52. As illustrated in steps 54 and 56, the determination of the product can be based on the type of article and / or type of dirt. For example, when cups of coffee are detected as the type of article, certain concentrated chemicals are selected, such as concentrated chlorine, oxidizer or chelater, for application by spraying directly on the dirty surface of the cup. Similarly, when pots and pans are detected as the type of article, a concentrated, metal-protecting, or penetrating degreasing surfactant is sprayed directly onto the pots and pans. The contact time of the chemical with the pots and pans is controlled to allow the surfactant to work. In the wash cycle, the duration of the recirculated wash can be increased to provide additional mechanical action for cleaning pots and pans. Once the type of article is identified, a chemical distribution sequence is determined according to step 58. The type of article being cleaned also determines the distribution points for the chemicals to be applied directly to the dirty surfaces of the products. items being cleaned (see step 60). Having identified one or more chemicals for direct spraying on the dirty surface of the article, controller 44 communicates a distribution signal to chemical distributor 46 shown in figure 1 to distribute the desired chemical through desired spray points, be they the lower spray points 48 or the upper spray points 50, depending on the article and / or dirt in the article. Depending on the type of article and / or the type of dirt on the article, the step time can be controlled to allow additional chemical contact time on the dirty surface. The liquid from the wash tank is then recirculated to wash the articles for a duration and in one direction as specified in figure 2. The articles are then rinsed for a duration and in one direction as specified in figure 2.
    [0018] Figure 4 illustrates an article-dependent washing cycle according to a possible embodiment of the present invention. As shown above, the articles to be imposed are loaded for cleaning as illustrated in step 66. User interface 42 on the cleaning apparatus 20 allows the operator or user to manually register the type of article and / or type of dirt on the article. If the operator or user manually selects the item type as illustrated in step 70, user interface 42, in one embodiment, provides a list of item types for the user to select based on items 34 loaded in rack 36. The list types of items can include plates, cups, glasses, serving dishes, pots and pans, trays, etc. Alternatively, the cleaning apparatus 20 can automatically detect the identifier associated with the type of article in rack 36 as illustrated in step 72 and described above. Once the type of article is detected, a washing cycle is activated, encompassing steps 1, 2, 3 and 4 illustrated in figure 2 for both soft and hard water situations. In the case where hard water is used, the detergent concentration can be increased and / or chelant can be applied directly to the article. Controller 44 can be programmed to adjust the washing sequences for each wash cycle shown in figure 2 based on a hard water signal received from a water sensor (not shown) on the cleaning device 20. The type of water is considered a component of a chemical combination for the purpose of formulating the chemicals to be used, the amount of chemical and detergent, the duration of the washing and rinsing cycles, etc. For example, controller 44 automatically customizes the concentrated chemical application sequence, washing sequence, rinsing sequence, and / or detergent quantity based on the condition of the water. Water type selections can include without limitation hard water, medium-hard water, soft water, distilled water, or RO (reverse osmosis) water and other water quality or water source selections. The water cycle identifies the type of chemical based on the article or type of dirt to be distributed, the distribution sequence, the distribution time, the duration of the washing cycle and the distribution spray points for the chemical to be distributed. be applied directly to the dirty surfaces of the article as illustrated in step 74. The washing and rinsing sequences can also be customized in a similar way to the concentrated product distribution sequence as illustrated in step 74. Before or after applying the chemical directly to dirty surfaces of the articles, the washing sequence or cycle can include a circulated wash as illustrated in step 76. The articles can be cleaned with the recirculated wash illustrated in step 78 before or after a wash cycle step where the chemical is applied directly to the dirty surface of the article. Similarly, after or before a recirculated wash, the selected chemicals can be applied directly to the article for a desired amount of time, such as the duration of the sauce, from above, from below or from both points. spray 48 and 50 on the cleaning apparatus 20 as shown in step 80. Steps 78 and 80 can be repeated as shown in figure 2 until the cleaning cycle or sequence is completed as shown in step 82.
    [0019] As discussed above, figure 2 includes illustrative washing cycles or sequences for varying the types of article including plates, cups, glasses, dishes, pots and pans and pans with aluminum coating. Since the cleaning apparatus 20 is adapted to identify the type of article 34 to be cleaned based on manual or automated detection, different concentrated chemicals are sprayed on individual types of articles according to the washing cycle or sequence illustrated in the figure 2. The distribution sequence is identified in figure 2 as step 1, 2, 3 and step 4 being the final rinse. These cumulative distribution sequences represent the washing cycle for each type of article. The chemical distribution sequence or the order in which each step occurs depends on the type of article. In each of the various distribution sequences, certain steps may not be activated and are indicated for being eliminated for the appropriate cell in both tables shown in figure 2. The wash cycle can be additionally customized based on the type of water, such as as shown in the upper table for soft water and the lower table for hard water. Each distribution sequence generally includes a step time or time required for the step to start and end. Some distribution sequences may not include spraying the chemical onto the dirty surface of the article being cleaned. For example, the first distribution sequence or step 1 for the dishes illustrates such a case where a spray of concentrated chemical is not applied during the first distribution sequence or steps. The dispensing sequence or step also includes a recirculated washing concentration indicating the detergent concentration for the liquid in the washing tank 26 of the cleaning apparatus 20. The dispensing sequence or step also includes the location of the spray point that may be applicable not only to the chemical being applied to the dirt in the article, but also to the recirculation of the liquid in the wash tank 26 via the lower wash spray arm and / or the upper wash spray arm for a wash cycle and the spray arm bottom rinse and / or the top rinse spray arm. Thus, to conserve energy and apply the chemical, washing and rinsing fluids to the dirty or suitable surface of the article, controller 44 can control the distribution point for the chemical, including the liquid distribution points washing and rinsing liquid. For example, the first stage or sequence of distribution in the dishwashing cycle includes spraying the recirculated wash having a detergent concentration of 0.1% through the top or top wash spray arms 32 in the cleaning apparatus 20 The volume wash concentration can also be personality for each water condition detected, as described above. Volume washing can often include a lower concentration of detergent with the addition of chemicals that are applied directly to the article that ends in the volume washing liquid. Since the dirty surface of a plate is generally facing upwards in rack 36, the distribution of the liquid from the upper spray arms provides the most efficient use of the cleaning apparatus 20 for removing dirt from the dirty surfaces of the plates. In step 2, acid is sprayed from the upper spray points 50 onto the dirty surfaces of the dishes and left to run, for example, for a duration of 4 seconds. Controlling the distribution of chemicals can be achieved by such methods as using a configurable timer. In step 3, the liquid is pumped from the wash tank 26 through both the upper and lower wash spray arms 30 and 32 for a period of 25 seconds. Finally, step 4 or fourth step in the dispensing sequence for the washing cycle includes rinsing dishes using the upper rinse spray arm 40 on the cleaning apparatus 20 for a duration of 10 seconds. In one embodiment of the present invention, the duration of the cycle is the minimum required by the National Hygiene Foundation ("NSF"). In another alternative embodiment, the cycle length can be a predetermined pattern configured for a particular system. Other combinations of time durations can be used. Figure 2 illustrates illustrative distribution cycles for several other types of articles. The cycle order combinations are as numerous as needed.
    [0020] The present invention contemplates the use of several types of chemical products. A number of acids can be used, and preferred acids can include citric acid, urea sulfate, methane sulfonic acid, gluconic acid, etc. Separate chemicals can be used independently of such oxidizers, chelators, enzymes, surfactants, etc. The detergent referred to in figure 2 can be an alkaline detergent such as a caustic based detergent or an ash based detergent.
    [0021] According to the present invention, the chemicals applied directly to the dirty surfaces of the articles are changed instead of recirculating in the volume washing liquid in the washing tank 26 as is traditionally done. Since the volume of water in the water tank 26, the concentration of chemical or detergent can be changed quickly and immediately so that the washing and rinsing cycles are customized specifically for the type of article, concentrated chemical products distributed, condition of water, etc. In addition, in the present invention, the concentrated product applied directly to the article ends in the washing tank 26 and is used for subsequent washing cycles. The application of chemicals directly to the surface of the articles to be cleaned allows the specific chemicals for the article to be used for each washing cycle without having to change the chemistry of the volume washing tank in the washing tank 26. Additionally, this The invention provides a means to reduce the amount of chemical used since the chemical is applied directly to the dirty surface of the article as opposed to the volume washing tank to achieve a desired level of concentration to perform a similar cleaning function. The ability to control the direct application of chemical to the dirty surface of the article without having to control the chemistry or chemical concentration within the volume wash tank provides savings in both the amount of chemistry being used and the water being used for carry out the various washing and rinsing cycles. The present invention also provides the flexibility to change and customize, immediately, the type of chemical being applied directly to the dirty surface of the article being cleaned without changing the chemistry of the volume washing tank inside the washing tank 26 of the cleaning apparatus 20 In addition, the direction from which the chemical, washing and rinsing liquid is applied to the article can also be changed and customized, immediately, to conserve energy, water, chemical and to prevent waste just as where the product is. chemical, washing and rinsing liquids are being sprayed onto surfaces of an article that are not usually soiled or that are clean. Controlling the direction of spraying of the chemical, washing liquids and rinsing also allows each washing cycle to be specifically customized according to the type of article and its position and / or relative orientation in rack 36 when positioned in the cleaning apparatus 20 For example, dishes are usually face up and spraying chemical, washing liquids and rinsing on the back of the dish throughout the wash cycle is a waste. In addition, since wash cycle time durations are often desirably short, the type of chemical used to clean dirt from articles is generally aggressive and can damage and corrode both the cleaning device and its components and the article to be cleaned. clean. For example, high levels of acid can corrode low grade steel dishes and utensils. By detecting the type of article and selecting the appropriate chemical and quantity according to the specific article, the present invention controls corrosion and damage to the type of article, the cleaning of the apparatus and its components while being sufficiently aggressive to clean types of articles even more sensitive.
    [0022] In an alternative mode, the types of washed items can be tracked and printed, which is an additional benefit for the customer. For example, the user can obtain information on the dates and times when the types of articles are washed, and can adjust the cleaning supply inventories accordingly. In addition, peak cleaning device usage periods can be tracked and reported. This can be used by the user, for example, to assess work requirements and keep costs low. These types of reports can be viewed and / or printed in the form of text or graphics.
    [0023] With the chemical distribution sequence and distribution location optimized for the particular article and / or type of dirt, additional benefits include the ability to do such things as rinsing a cup rack with additional rinsing additive; add a bleaching agent for a final rinse to help control stains; use more aggressive chemicals to wash pots and pans; completely optimize and mix formulas based on the type of article being washed; extend or shorten the washing time based on the article being washed; provide different options of final rinse to sanitize or to control water stains. These additionally result in fewer additional washes and fewer stains, along with more efficient cycle sequences and durations.
    [0024] While the system described above as effectively adapted to fulfill the objectives mentioned above, it should be understood that the invention should not be limited to the specific preferred embodiments of the cleaning apparatus and method presented above. Instead, it should be considered to include all reasonable equivalences to the present matter of the appended claims.
