[0064] The following discussion is presented to enable a person skilled in the art to make and use embodiments of the invention. Various modifications to the illustrated embodiments will be readily apparent to those skilled in the art, and the generic principles herein can be applied to other embodiments and applications without departing from embodiments of the invention. Thus, embodiments of the invention are not intended to be limited to embodiments shown, but are to be accorded the widest scope consistent with the principles and features disclosed herein. The following detailed description is to be read with reference to the figures, in which like elements in different figures have like reference numerals. The figures, which are not necessarily to scale, depict selected embodiments and are not intended to limit the scope of embodiments of the invention. Skilled artisans will recognize the examples provided herein have many useful alternatives and fall within the scope of embodiments of the invention.

[0065] Dispensing systems can be used to dispense flowable food products (e.g., sauces, dressings, condiments, etc.). Flowable food products can include a wide variety of products, such as condiments (e.g., ketchup, mustard, mayonnaise, tartar sauce, etc.), syrups, dressings, cheeses, fudge, caramel, sauces, wing sauces or other similar food products that can flow and thus be pumped. Flowable food products can include a wide variety of viscosities, non-Newtonian properties, can include small particulates and can be dispensed in a wide range of temperatures from cold to hot. Flowable food products can also be heated food products such as liquid cheese, hot ice cream toppings or chilled food products.

[0066] For example, a dispensing system can include one or more dispensers that can dispense a type or quantity of a flowable food product based on an input signal from a worker or kitchen management system (e.g., a system configured to manage and operate various kitchen operations, including ordering, food preparation, inventory, etc.). Correspondingly, an input signal can be provided to the dispensing system to dispense a desired amount of one or more flowable food products. The input signal may vary depending on the particular application, but in general, can be a manual input (e.g., from a worker) or electronic signal (e.g., from a management system) that can include a quantity or type of flowable food product. In other cases, the input signal can include information on a type or quantity of food product (e.g., chicken wings, cauliflower, or other type of food product) and the dispensing system may dispense a quantity or type of flowable food product based on the food product to which the flowable food product is being added. Accordingly, the dispensing system can be used as a manual dispensing system, in which the type or quantity of flowable food product is determined by a worker, or as an automatic dispensing system that is configured to determine the type or quantity of flowable food product being dispensed (e.g., via an electronic controller configured to receive an input signal and determine an amount or type of flowable food product to dispense based on the input signal). The dispenser can dispense a known and repeatable volume of flowable food product based upon a selection made by the user, or other input signal received by the system.

[0067] In general, a dispenser for a dispensing system can include a base unit configured to dispense a flowable food product that can accurately control the operation of a pump to dispense the desired amount and volume of the flowable food product. The base unit can include an interface (i.e., a user or communication interface) configured to receive an input signal from a useror kitchen management system. Based on the input signal, the base unit can operate a pump therein to dispense the desired amount or type of flowable food product. In some cases, a quantity of flowable food product can be stored in a reservoir, which can be selectively coupled with the pump. The reservoir can be a container configured to store the flowable food product for dispensing. Correspondingly, the reservoir can be configured to allow flowable food product to be poured directly therein, or the reservoir can be configured to hold a separate container (e.g., a ridged container or flexible bag) that contains the flowable food product. In either case, as the flowable food product is dispensed, the reservoir will gradually become depleted, requiring that the reservoir be refilled from time to time.

[0068] In some non-limiting examples, the reservoir can be configured as a removeable reservoir that can be selectively connected and disconnected from the base unit to allow for refilling, as well as for cleaning the base unit (e.g., the pump and any internal tubing, allowing for clean-in-place applications).

[0069] FIGS. 1-3 illustrate a non-limiting example of a dispensing system 100 configured to dispense a flowable food product, according to aspects of the disclosure. The dispensing system 100 can include one or more dispensers 102, each of which can be configured to dispense a quantity or type of flowable food product. As illustrated, dispensers 102 can be arranged in a variety of ways relative to one another. In particular, dispensers 102 can be arranged in a linear or stacked configuration. Correspondingly, the dispenser 102 can be configured to couple with other dispensers 102 in the dispensing system 100. For example, the dispenser 102 can include feet 104 arranged along a bottom surface 106 of the dispenser 102, which can be configured to engage with a support surface. The support surface can be, for example, a table, counter, workstation, etc. A support surface can also be another dispenser when arranged in a stacked configuration. Accordingly, in some cases, a top surface 108 of the dispenser 102 can define pads 110 configured to engage with feet 104 of a corresponding dispenser stacked thereon. As shown in FIG. 2, the pads 110 can be formed as recesses configured to receive feet 104 of another dispenser 102 stacked thereon. Similarly, dispensers 102 can also be configured to couple with one another in a side-by- side configuration. In some non-limiting examples, the dispenser 102 can be magnetically connected to another dispenser 102 by way of magnets. In other non-limiting examples, dispensers can be coupled in other ways (e.g., via fasteners, brackets, latches, etc.) to secure both stacked andside-by-side configurations of dispensers. In yet other non-limiting examples, and depending on the particular application, the dispensers 102 can be arranged separately from one another, or in various groups. The particular arrangement of the dispensing system 100 can be selected in accordance with desired layout or workflow of a kitchen or work environment. Thus, while FIG. 1 shows a two-by-two arrangement of dispensers 102 (e.g., stacked two dispensers high and two across), other arrangements with more or fewer dispensers 102 are possible. For example, two to sixteen food product dispensers 102 can be organized in a side-by-side relationship.

[0070] As mentioned above, the dispensing system 100 can include one or more dispensers 102 to dispense a type or quantity of flowable food product. In some cases, a single dispenser 102 can be configured to dispense a desired quantity (e.g., by volume or by weight) of one or more types of a flowable food product (e.g., via one or more nozzles). Each dispenser 102 can include a base unit 120 (e.g., a dispensing unit) that is configured to couple to a reservoir 122 to dispense a flowable food product therein. More specifically, the reservoir 122 can be inserted into an opening 124 (e.g., a receiving area) of the base unit 120 to dispense flowable food product, and removed from the opening 124 to allow for cleaning and / or refilling of the reservoir 122, as needed. The opening 124 can be shaped to receive at least a portion of the reservoir 122.

[0071] When a reservoir (e.g., reservoir 122) is coupled to a base unit (e.g., base unit 120), the base unit 120 can control dispensing of the flowable food product based on an input signal. The input signal can be provided as a manual input signal from a worker (e.g., via a user interface), or as an electronic signal provided by an external kitchen management system (e.g., for automatic dispensing based on a customer order). In some cases, the input signal may include information as to the type or quantity of flowable food product. In some case, the input signal may include information on the customer order and the base unit can be configured to determine and automatically dispense a corresponding type or quantity of flowable food product based on the order. For example, the base unit can dispense a flowable food product based on a type or quantity of a food item in an order.

[0072] The base unit 120 can further include a user interface 134 that can be configured to receive a user input or to display a status of the dispenser to a user. In the illustrated non-limiting example, the base unit 120 includes the user interface 134 configured as a touch screen that can allow a user to provide an input signal via virtual buttons displayed thereon. In other non-limitingexamples, physical input controls (e.g., dials, buttons, switches, etc.) can be provided. The user interface 134 may also display a status of the dispenser 102 to a user. For example, the user interface 134 can display the type of flowable food product being or available to be dispensed, a quantity being dispensed, a fill level of the reservoir, etc. In other non-limiting examples, the other types of status indicators may be provided, including, for example, visual indicators (e.g., lights), auditory indicators, etc. Furthermore, while each dispenser 102 of the dispensing system 100 may be provided with its own user interface, as shown in the illustrated non-limiting example, the dispensing system 100 may include a single user interface configured to control multiple dispensers 102. As will be discussed in further details herein, the user interface 134 can also place the dispenser 102 into a cleaning mode and can control a pump system 140 of the dispenser 102.

[0073] The user interface 134 can be configured to allow the user to control an amount of dispensed food product based on a variety of input options, and in some cases, may be customizable by a user. For example, a user interface can be configured for any use, portion size, dispensing amount or in any other way desired. It is contemplated that other different configurations for the user interface of the control panel could be utilized while operating within the scope of the present disclosure, such as but not limited to specific control buttons or any other type of interface. In some non-limiting examples, a user interface could include multiple selection areas that allow the operator to select between the type of food product upon which the dispensed sauce will be placed. It is contemplated that these selection buttons could identify a wide variety of different types of food products depending upon the desired use of the food product dispenser of the present disclosure.

[0074] To control the dispenser 102 and dispense the flowable food product, the base unit 120 can include a controller 142 that is configured to receive the input signal e.g., from the user interface 134) and to control the pump system 140 to pump flowable product through the base unit from the reservoir 122. In some cases, the controller 142 can be configured to determine the amount of flowable food product to be dispensed based on the input signal. For example, the controller 142 can include an encoder to monitor operation of the pump to accurately control an amount of flowable food product that is dispensed. Correspondingly, when and input signal is received by the controller 142, the controller 142 can make a determination of the amount of timeor the number of rotations the pump system 140 needs to operate to dispense the desired amount of sauce onto the food product.

[0075] With particular reference to FIGS. 3, the base unit 120 includes a housing 144. The housing 144 can be formed of a durable, cleanable material, such as metals, polymers, etc., and may include one or more removal panels (e.g., side, top, bottom, back, front, etc.) that can be removed to allow for cleaning or maintenance of any internal components. The housing 144 houses the pump system 140 and the controller 142 (e.g., an electronic controller) that is configured to operate the pump system 140 to dispense a flowable food product (e.g., to pump a desired amount of flowable food product from the reservoir 122). The controller 142 can receive power from a power source inside or outside of the dispenser 102.

[0076] Based on the input signal, the controller 142 can operate the pump system 140 to control dispensing of the flowable food product from the reservoir 122. The pump system 140 is disposed within the housing 144 of the base unit 120 and includes a base unit connector or inlet 150 (e.g., a first connector that defines an inlet of the base unit 120), which is configured to couple with and receive the flowable food product from the reservoir 122, as well as a nozzle outlet 152 (e.g., an outlet of the base unit 120) configured to dispense the flowable food product from the dispenser 102. The inlet 150 can extend into the opening 124 of the base unit 120 to allow the inlet 150 to couple with the reservoir 122 when it is inserted into the opening 124. However, in some non-limiting examples, the inlet 150 can be positioned on a different area of the dispenser 102. The nozzle outlet 152 can be disposed on a front side 158 of the base unit 120 and can formed from a metal (e.g., stainless steel, aluminum, etc.) or polymeric material that is durable and can be easily cleaned. More specifically, the nozzle outlet 152 may define a frontmost part of the pump system 140. As will be discussed in further details below, the pump system 140 can also be used to pump cleaning solution through the dispenser 102.

[0077] To move the flowable food product from the inlet 150 to the nozzle outlet 152, pump system 140 can further include a pump 160 (e.g., a peristaltic, flexible impeller, modular, or other type pump) configured to transport flowable food product from the reservoir 122 to the nozzle outlet 152. The particular type of pump 160 selected based on the type of flowable food product being dispensed. In this case, the pump 160 is secured to a back wall of the housing 144 that is configured to engage with the reservoir 122. However, the pump 160 may also be arrangeddifferently within the housing 144 based on the particular application. In this way, the pump 160 can be separated from the reservoir 122 to reduce or eliminate direct contact with the flowable food product during operation of the dispensing system 100, while still allowing the pump interface (e.g., the inlet 150) to be cleaned in place when the reservoir 122 is removed.

[0078] The controller 142 can supply power to the pump 160 (e.g., a motor 161 of the pump 160) to cause flow through the pump system 140. In some cases, the motor 161 can be operatively coupled to the pump 160 via a direct connection to a drive shaft of the motor 161, or via a transmission (e.g., a geartrain, drive belt, etc.). Correspondingly, the pump system 140 may further include a plurality of conduits 164 (e.g., flexible, or rigid tubing, pipe, or hose) (see FIG. 3) to allow flowable food product to flow through the dispenser. In some cases, the pump 160 can be a food-grade pump that can be configured to allow for clean-in-place applications. As will be discussed in further details below, the pump system 140 can be operated to clean the dispenser 102 without requiring that a user take the dispenser 102 apart for cleaning.

[0079] As mentioned above, a reservoir can be configured to hold a flowable food product and to couple with the pump system 140 of the base unit 120 for dispensing. With reference to FIG. 2, the reservoir 122 can be configured to hold and temporarily store flowable food product. In general, the reservoir 122 can include an interior cavity that is configured to hold the flowable food product. In some cases, the reservoir 122 can define a handle 171 (see FIG. 2) to allow a user to grasp the reservoir 122.

[0080] In some cases, a base unit of a dispensing system (e.g., one or more dispensers) are configured as clean-in-place devices. Clean-in-place devices allow a user to clean a base unit a dispenser without requiring that the user disassemble the base unit; although removal of a reservoir may be required in some instances. As one example, a clean-in-place dispensing system can eliminate the need for a user to remove and take apart a pump system for cleaning. This reduces cleaning time and makes cleaning less labor intensive.

[0081] Further advantages can be obtained when a clean-in-place system is used with a corresponding cleaning system, as described herein. A cleaning system can allow a user to easily move all necessary cleaning supplies proximate a dispensing system for cleaning, as well as allowing for multiple dispensers to be cleaned simultaneously. The cleaning system can include a support structure configured to support one or more containers (e.g., tanks). The support structurecan be a cart that can be moved between a storage location and the dispensing system. The containers can include one or more containers configured to carry a cleaning solution (e.g., sanitizer) that is provided to the dispensing system and one or more containers to catch used cleaning solution. One or more connectors can be provided on the containers to allow tubing to be coupled between the cleaning system and the dispensing system to transport fresh and used cleaning solution therebetween. In some cases, the one or more connectors may be part of a manifold. In some cases, the cleaning system can utilize the pump from the dispenser system to move cleaning solution through the system. In some cases, the cleaning system may include a separate pump system that can be used to move cleaning solution through the dispensing system or to evacuate used solution from the cleaning system. The cleaning system can allow the dispensing system to operate a cleaning operation automatically. In some cases, the dispensing system can automatically enter a priming mode following the cleaning operation.

[0082] With reference to FIG. 4, a side view of a portable cleaning system 200 attached to the dispenser 102 is illustrated. As described above, the dispenser 102 is used to dispense a flowable food product. In typical operation, it is often necessary to clean the dispenser 102 after a certain time of use or another period. The portable cleaning system 200 can be used to clean the pump system 140 after use in order to remove food product from within the pump system 140. The portable cleaning system 200 includes a cart 210 that can be moved throughout the kitchen or work environment. The cart 210 includes wheels 212 at a bottom end 214 of the cart 210. The portable cleaning system 200 can further includes a sanitizer tank 220, a wastewater tank 222, and, optionally, a cleaning pump system 224. In some non-limiting examples, the portable cleaning system 200 can include two or more of the sanitizer tanks 220. As illustrated in FIG. 4, the cart 210 includes a top shelf 230 that secures the sanitizer tank 220 and a bottom shelf 232 that secures the wastewater tank 222 and the cleaning pump system 224. The top shelf 230 is positioned above the bottom shelf 232. In some non-limiting examples, the portable cleaning system 200 may also comprise a storage shelf that may hold rags, paper towels, etc.

[0083] With continued reference to FIG. 4, the sanitizer tank 220 is configured to store a cleaning solution therein. It is contemplated that the sanitizer tank 220 may include any type of cleaning solution and / or fluid therein. The particular type of cleaning solution may be selected based on the type of food product being dispensed. The sanitizer tank 220 may include aremovable top or cap to allow the sanitizer tank 220 to be filled with the cleaning solution. The sanitizer tank 220 also comprises a plurality of connectors, here, shown as quick connect fittings 240 with shutoff valves. Other examples may utilize other types of connectors. The sanitizer tank 220 may include any number of quick connect fittings 240 to allow the cleaning system to couple to one or more dispensers 102 of the dispensing system 100 for cleaning simultaneously or sequentially. For example, in some non-limiting examples, the sanitizer tank 220 may comprise one, two, three, four, five, six, seven, eight, or more quick connect fittings 240. In some nonlimiting examples, the sanitizer tank 220 may include six quick connect fittings 240. Correspondingly, one or more sanitizer tubes 242 with quick connect fittings (e.g., corresponding connectors configured to connect the sanitizer tank 220). Thus, both ends of each of the sanitizer tubes 242 can include the quick connect fittings 240. As noted herein, the sanitizer tank 220 can include any number of quick connect fittings 240 and sanitizer tubes 242 extending therefrom. However, for ease of description and illustration, FIG. 4 illustrates a single sanitizer tube 242 and a single quick connect fitting 240 and only the single sanitizer tube 242 will be described in detail herein. Each of the single sanitizer tubes 242 can be identical, or they may be different from one another (e.g., in length, diameter, material, etc.) to allow for connections to different types of dispensers or to clean a dispenser of different types of food products.

[0084] With continued reference to FIG. 4, a first end 250 of the sanitizer tube 242 secures with the quick connect fitting 240 on the sanitizer tank 220 and a second end 252 of the sanitizer tube 242 is configured to connect to the dispenser 102. Specifically, the second end 252 of the sanitizer tube 242 is configured to connect to the inlet 150 of the dispenser 102. In some cases, the second end 252 can fit directly onto the inlet 150 (e.g., via a barb on the inlet 150). In other cases, the second end 252 can be provided with a connector (e.g., a quick fit connector or other type of connector) that corresponds with a connector of the inlet 150. As illustrated in FIG. 4, the reservoir 122 is removed to allow access to the inlet 150 of the dispenser 102.

[0085] In some non-limiting examples, the sanitizer tank 220 may be vented (e.g., via a vent 221, see FIG. 4)to allow consistent flow of the cleaning solution therein. A vent can be a separate vent that is coupled to a tank (e.g., the sanitizer tank 220), or a vent can be integrated into another component (e.g., a cap of a tank).

[0086] The volume of a tank can be selected to ensure enough cleaning product (sanitizer, clean water) is available to clean a desired number of dispensers. Correspondingly, a waste tank can typically be larger than a sanitizer or water tank to ensure that all waste can be captured without the tank overflowing. Thus, a waster tank can have a capacity that is greater or equal to the combined volume of a sanitizer tank and a water tank, For example in some cases, the sanitizer tank 220 may have a capacity of five gallons. However, it is contemplated that the sanitizer tank 220 may have any volume capacity. Where multiple sanitizer tanks 220 are used each tank may have the same or different capacities. The sanitizer tanks 220 can collectively hold a desired volume of cleaning solution. The particular volume may be selected in accordance with an amount of cleaning solution required for a cleaning operation of the dispensing system 100. For example, the sanitizer tank 220 may have a capacity of one, two, three, four, five, ten, fifteen, or more gallons (or any range therein). As illustrated in FIG. 4, the quick connect fitting 240 is positioned on a side of the sanitizer tank 220. However, in some non-limiting examples, the quick connect fitting(s) 240 can be positioned on a top of the sanitizer tank 220 or on a combination of the side and top of the sanitizer tank 220. Further, in some non-limiting examples, the sanitizer tank 220 may include a heater (e.g., heater 223, see FIG. 4) to heat the cleaning solution therein.

[0087] With continued reference to FIG. 4, the wastewater tank 222 is configured to store the used cleaning solution after the cleaning solution has cycled through the dispenser 102. Therefore, waste from the dispenser 102 will also be stored in the wastewater tank 222 after use. Similar to the sanitizer tank 220, the wastewater tank 222 can include a plurality of wastewater tank quick connect fittings 260 with shutoff valves therein. In some non-limiting examples, the wastewater tank 222 may include any number of wastewater tank quick connect fittings 260. For example, the wastewater tank 222 may comprise one, two, three, four, five, six, seven, eight, or more wastewater tank quick connect fittings 260. In some non-limiting examples, the wastewater tank 222 may include 6 wastewater tank quick connect fittings 260. In preferred examples, the wastewater tank 222 has the same number of wastewater tank quick connect fittings 260 as the number of quick connect fittings 240 on the sanitizer tank 220. One or more wastewater tubes 262 with quick connect fittings can be connected to the wastewater tank quick connect fittings 260 on the wastewater tank 222. As noted herein, the wastewater tank 222 can include any number of the wastewater tank quick connect fittings 260 and wastewater tubes 262 extending therefrom.However, for ease of description and illustration, FIG. 4 illustrates a single wastewater tube 262 and a single wastewater tank quick connect fitting 260 and only the single wastewater tube 262 will be described in detail herein. Each of the single wastewater tubes 262 can be identical, or they may be different from one another. In some non-limiting examples, each of the wastewater tubes 262 are the same as each of the sanitizer tubes 242.

[0088] With continued reference to FIG. 4, a first end 270 of the wastewater tube 262 secures with the wastewater tank quick connect fitting 260 on the wastewater tank 222 and a second end 272 of the wastewater tube 262 is configured to connect to the dispenser 102. Specifically, the second end 272 of the wastewater tube 262 is configured to connect to the nozzle outlet 152 of the dispenser 102. The second end 272 can connect to the nozzle outlet 152 directly or via a connector. Further, in some non-limiting examples, the wastewater tank 222 may have a minimum capacity of ten gallons. However, it is contemplated that the wastewater tank 222 may have any volume capacity. For example, the wastewater tank 222 may have a capacity of one, five, ten, fifteen, twenty, or more gallons (or any range therein). In some cases, the wastewater tank 222 can include one or more wastewater tanks 222 and the total capacity (e.g., of the wastewater tank 222 can be greater than a maximum capacity of the sanitizer tanks 220 to ensure that the wastewater tank 222 can accommodate all the cleaning solution in addition to any waster food product from the dispensing system 100. As illustrated in FIG. 4, the wastewater tank quick connect fitting 260 is positioned on a top of the wastewater tank 222. However, in some nonlimiting examples, the wastewater tank quick connect fitting(s) 260 can be positioned on a side of the wastewater tank 222 or on a combination of the side and top of the wastewater tank 222.

[0089] It is contemplated that the quick connect fittings 240 on the sanitizer tank 220, the wastewater tank quick connect fittings 260 on the wastewater tank 222, and the quick connect fittings on the sanitizer tubes 242 and the wastewater tubes 262 can be any type of fitting or connecting element as long as the sanitizer tubes 242 and the wastewater tubes 262 can attach to the sanitizer tank 220 and the wastewater tank 222, respectively. As noted herein, the quick connect fittings 240 on the sanitizer tank 220 are complementary with the quick connect fittings on the sanitizer tubes 242, and the wastewater tank quick connect fittings 260 on the wastewater tank 222 are complementary with the quick connect fittings on the wastewater tubes 262. In some non-limiting examples, the quick connect fittings 240 on the sanitizer tank 220, the quick connectfittings 260 on the wastewater tank 222, and the quick connect fittings on the sanitizer tubes 242 and the wastewater tubes 262 are the same type of quick connect fitting. In other examples, a wastewater tank can be provided with one or more openings. The one or more openings can each receive one or more tubes to allow wastewater to be drained.

[0090] With continued reference to FIG. 4, the wastewater tank 222 also comprises an exit valve 280 on a bottom side 282 of the wastewater tank 222 that can be opened to evacuate wastewater from the wastewater tank 222. The exit valve 280 can extend through the bottom shelf 232 of the cart 210. In other examples, the exit valve 280 can be positioned differently, such as along a side or top surface of the wastewater tank 222. In some cases, the exit valve 280 can be positioned to allow the used cleaning solution to be evacuated via gravity. For example, a user can open the exit valve 280 to allow the cleaning solution to empty into a floor drain or other disposal system. In some cases, a user may operate the exit valve 280 by hand or via a foot pedal. In yet other cases, the valve may be electronically controlled.

[0091] As mentioned above, a wastewater tank can optionally include a pump system for forced evacuation of the wastewater tank. Such arrangements can be beneficial to allow emptying of the wastewater tank at elevated location, such as a sink while eliminating the need to remove or lift the wastewater tank. A pump system can be a manually operated pump system or an electronically operated pump system that includes an electric motor. As illustrated in FIG. 4, the cleaning pump system 224 is configured as an electronic pump system that is positioned adjacent the wastewater tank 222, such that is supported on the cart 210. In some non-limiting examples, the cleaning pump system 224 can be attached and / or is integral (unitary) with the wastewater tank 222. The cleaning pump system 224 can assist with removing wastewater from the wastewater tank 222. For example, a hose or tube can be secured to the wastewater tank 222 and / or the cleaning pump system 224 and remove the wastewater from within the wastewater tank 222 by way of the cleaning pump system 224. In one non-limiting example, the hose can drain the wastewater into a sink.

[0092] In some cases, a pump controller a can be in communication with a dispensing unit to control a flow rate provided by the pump and prevent overpressure at the internal pump of the dispensing system 100. For example, to run the pump system 224, the pump system 224 can include a pump controller 225. The pump controller 225 can communicate via wired (e.g., ethernet,USB, etc.) or wireless connection (e.g., Bluetooth, WiFi, etc.) with a main controller 142 of the dispensers 102. In this way the dispensing system 100 can initiate pump operation or control a desired flow rate from the pump system 224. For example, the dispensing system 100 can send a signal to the pump controller 225 to operate a pump at a desired speed or to provide a desired flow rate. The flow rate can be substantially the same as a flow rate provided by operation of the internal pump 160 of the dispensing system 100. In some examples, the pump system 224 can include one or more sensors 226 (e.g., flow sensors, pressure sensors, current sensors) that can be monitored by the pump controller 225. Based on information from the sensors 226, the pump controller 225 can control pump operation to maintain a flow rate or maintain line pressure (e.g., pressure in the tubes 242, 262) below a predetermined threshold. In cases where a pump system is not provides an internal pump of a dispensing unit can be operated to draw fluids though the dispensing unit for cleaning, drying, rinsing, etc.

[0093] With continued reference to FIG. 4, the top shelf 230 of the cart 210 has a height Hl, i.e., perpendicular distance from the floor or other support surface, and the bottom shelf 232 of the cart 210 has a height H2, i.e., perpendicular distance from the floor. In some non -limiting examples, the height Hl of the top shelf 230 is between about twenty inches and about sixty inches, or about twenty-five inches and about fifty inches, or about thirty inches and about forty inches, or about thirty-five inches and about thirty-seven inches, or about thirty-six inches, or at least about twenty-five inches, or at least about thirty inches, or at least about thirty-six inches. In some nonlimiting examples, the height Hl of the top shelf 230 is no greater than about thirty-six inches. In some non-limiting examples, the top shelf 230 and the bottom shelf 232 have a width, i.e., distance into the page with respect to FIG. 4, of between about twelve inches and about twenty-four inches. In some non-limiting examples, the bottom shelf 232 has a height H2 of between about one inch and about forty inches, or about five inches and about thirty inches, or about ten inches and about twenty inches, or about twelve inches, or about twenty-four inches, or at least about five inches, or at least about ten inches, or at least about twelve inches.

[0094] In some cases, a cart can be configured to store tubes when the cleaning system is not in use. For example, the cart 210 may include a plurality of hooks. The plurality of hooks can hold and store the sanitizer tubes 242 and the wastewater tubes 262 when the tubes 242, 262 are not in use. Further, the sanitizer tubes 242 and the wastewater tubes 262 can be flexible tubingthat does not allow flavor migration and is compatible with cleaning sanitizers and / or detergents. As noted herein, the sanitizer tubes 242 and the wastewater tubes 262 are similar and, in some non-limiting examples, are identical to each other. Therefore, in the description and claims below, the sanitizer tubes 242 and the wastewater tubes 262 may be referred to as the tubes 242, 262. Further, as noted herein, the sanitizer tubes 242 may be referred to as a plurality of sanitizer tubes 242 and the wastewater tubes 262 may be referred to as a plurality of wastewater tubes 262.

[0095] As discussed above, the portable cleaning system 200 can be used to clean the interior conduits 164 of the dispenser 102. Once the sanitizer tube 242 is secured with the sanitizer tank 220 and the inlet 150 of the dispenser 102 and the wastewater tube 262 is secured with the wastewater tank 222 and the nozzle outlet 152 of the dispenser 102, cleaning solution from the sanitizer tank 220 can flow from the sanitizer tank 220, through the dispenser 102, and into the wastewater tank 222. This flow of cleaning solution can clean the portions of the pump system 140 that transport food product, including the pump 160 and the conduits 164, or other interior portions of the dispenser 102. As noted herein and as will be discussed in further details below, the portable cleaning system 200 can be used to clean multiple dispensers 102 at once. Therefore, the sanitizer tank 220 and the wastewater tank 222 can be connected to multiple dispensers 102 through multiple sanitizer tubes 242 and multiple wastewater tubes 262 to clean multiple dispensers 102 at once.

[0096] As noted herein, the flow of cleaning solution can be controlled by the pump system140 in the dispenser 102. Therefore, the dispenser 102 can power and control the portable cleaning system 200. Specifically, the controller 142 of the dispenser 102 controls the flow of solution though the portable cleaning system 200 and the dispenser 102 by way of the pump system 140. As will be discussed in further details herein, once a user initiates a cleaning mode on the dispenser 102, the controller 142 can supply power to the pump 160, via the motor 161, to cause the cleaning solution to flow through the pump system 140 from the sanitizer tank 220 and into the wastewater tank 222. The cleaning solution can clean the conduits 164 in the dispenser 102.

[0097] With reference to FIG. 5, a flowchart is depicted of a process 300 for cleaning the dispenser 102 by way of the portable cleaning system 200. While the example process is described with reference to the flowchart illustrated in FIG. 5, many other methods of using the portable cleaning system 200 and the dispenser 102 may alternatively be used. For example, the order ofexecution of the blocks may be rearranged, changed, eliminated, and / or combined to perform the process 300. As discussed above, the portable cleaning system 200 can be connected to multiple dispensers 102 at one time and clean multiple dispensers 102 at once. However, for ease of description and illustration, the following process 300 outlines the blocks for cleaning a single dispenser 102. The process 300 would be similar for multiple dispensers 102.

[0098] With reference to FIGS. 1-5, at block 302, the portable cleaning system 200 is connected to the dispenser 102. The portable cleaning system 200 may be moved from first location to a second location near the dispenser 102 wherein the tubes 242, 262 can be coupled between the cleaning system 200 and the dispensing system 100. As noted above, the portable cleaning system 200 includes the wheels 212 to allow the cleaning system to be easily moved from one location to another location. Once the portable cleaning system 200 is adjacent to the dispenser 102, the first end 250 of the sanitizer tube 242 can be attached to the sanitizer tank 220 by way of the quick connect fittings 240 on the sanitizer tank 220 and the quick connect fitting on the sanitizer tube 242. As discussed above, the sanitizer tube 242 also includes quick connect fittings that mate with the quick connect fittings 240 on the sanitizer tank 220 for easy attachment of the sanitizer tube 242 to the sanitizer tank 220. The second end 252 of the sanitizer tube 242 can connect to the inlet 150 of the dispenser 102. In some cases, to attach the sanitizer tube 242 to the inlet 150, the reservoir 122 may be removed from the dispenser 102. In some non-limiting examples, the inlet 150 may be positioned at a different portion of the dispenser 102. Further, in some nonlimiting examples, the dispenser 102 may include a cleaning inlet that is separate from the inlet 150. The cleaning inlet may connect with the conduits 164 of the pump system 140 and therefore allow cleaning solution to flow through the dispenser 102. Thus, in such examples, the reservoir 122 would not need to be removed in order to clean the dispenser 102.

[0099] Before or after the sanitizer tube 242 is connected, the wastewater tube 262 can also be secured to the wastewater tank 222 and the nozzle outlet 152. Specifically, the first end 270 of the wastewater tube 262 can secure to the wastewater tank quick connect fittings 260 on the wastewater tank 222 and the second end 272 of the wastewater tube 262 can be connected to the nozzle outlet 152. The wastewater tube 262 also includes a quick connect fitting 261 that mates with the wastewater tank quick connect fitting 260 for easy attachment of the wastewater tube 262 to the wastewater tank 222.

[0100] With the sanitizer tube 242 and the wastewater tube 262 are attached to the respective sanitizer tank 220 and the wastewater tank 222, the shutoff valves in the quick connect fitting 240 and the wastewater tank quick connect fitting 260 may be opened. In some non-limiting examples, the shutoff valve may be opened automatically once the respective tubes 242, 262 are attached thereto. In some non-limiting examples, the user may manually open the shutoff valves. Once the sanitizer tube 242 and the wastewater tube 262 are connected to the portable cleaning system 200 and the dispenser 102, portable cleaning system 200 is ready for operation. During or before block 302, cleaning solution can be added to the sanitizer tank 220. As described in greater detail below, the amount of cleaning solution added may be a minimum amount of cleaning solution required for appropriate cleaning or sanitizing of the dispensing system 100.

[0101] At block 304, a cleaning operation can be initiated. In one example, the cleaning operation can be initiated automatically upon connection of the cleaning system 200 with the dispensing system 100. In that regard, the cleaning system 200 and the dispensing system 100 may be configured to communicate with one another, or the dispensing system 100 may otherwise be configured to detect that the cleaning system 200 is connected for a cleaning operation. In other examples, the user initiates a cleaning mode on the dispenser 102. The cleaning mode can be initiated by the user through the user interface 134 on the dispenser 102. In some non-limiting examples, the user may have various cleaning options that the user can decide on through the user interface 134. For example, cleaning options may include a duration or type of cleaning operation. In some cases, the controller 142 can determine the type of cleaning operation based on a user input. The user input may include a type of cleaning solution, a type of food product, a cleaning interval (e.g., a daily or weekly cleaning interval). In some cases, one of more of the user inputs may be retained by memory of the controller 142, or may be transmitted by a kitchen management system. After the cleaning mode is initiated, at block 306, the controller 142 can operate the pump system 140 to pump cleaning solution through the dispenser 102 to clean the dispenser 102. Specifically, once the cleaning mode is initiated by the user at block 304, the dispenser 102 is cleaned by the cleaning solution in the portable cleaning system 200 at block 306. At block 306, the controller 142 can power and control the pump 160 and the motor 161 within the pump system 140 to pump cleaning solution from the sanitizer tank 220, through the dispenser 102, and into the wastewater tank 222. In other words, the cleaning solution flows from the sanitizer tank 220,through the sanitizer tube 242, through the conduits 164 of the pump system 140 in the dispenser 102, through the wastewater tube 262, and into the wastewater tank 222.

[0102] Following cleaning process with cleaning solution, a dispensing system can initiate a drying mode at block 308 to remove any remaining cleaning solution from the dispensing system. In the drying mode at block 308, the motor 161 of the pump 160 pumps air through the dispenser 102 to dry the conduits 164 therein. Any remaining or residual cleaning solution can be pumped into the wastewater tank 222. The dispensing system 100 can enter a drying mode manually or automatically. In some non-limiting examples, the dispenser can go through a drying mode at block 308 after a predefined amount of cleaning time (depending on the settings and inputs of the user). In some non-limiting examples, the shutoff valve on the quick connect fitting 240 of the sanitizer tank 220 can be closed (either manually or through removal of the sanitizer tube 242 from the sanitizer tank 220) in order for cleaning solution to stop flowing out of the sanitizer tank 220 and into the sanitizer tube 242. Once the shutoff valve on the sanitizer tank 220 is closed the sanitizer tube 242 can be disconnected from the dispenser 102 and the drying mode can be initiated. In some non-limiting examples, the drying mode can be initiated once the sanitizer tank 220 runs out of cleaning solution. Thus, in such cases, the sanitizer tube 242 does not need to be disconnected from the sanitizer tank 220 and / or the dispenser 102.

[0103] Further, in some non-limiting examples, the dispenser 102, by way of the controller 142 can automatically determine once the sanitizer tube 242 is disconnected from the inlet 150 in order to automatically start the drying mode. For example, a switch may be activated or deactivated based on the sanitizer tube 242 being connected or disconnected between the dispensing system 100 and the cleaning system 200. In some non-limiting examples, the user may use the user interface 134 to initiate an end of the cleaning mode and / or a beginning of the drying mode. Furthermore, in some non-limiting examples, the dispenser 102, by way of the controller 142, the pump system 140, and / or various sensors, can determine when air (and not a liquid) is being pumped through the dispenser, e.g., when the cleaning solution runs out in the sanitizer tank 220 or the shutoff valve on the quick connect fitting 240 of the sanitizer tank 220 is closed, and automatically initiate the drying mode. For example, the controller 142 may be configured to detect a current demand or speed of the motor 161, which may indicate whether the pump 160 is pumping cleaning solution or air. At block308, air cycles through the pump system140 to dry the conduit and remove any access cleaning solution from therein. In some cases, drying may occur for a predetermined period of time. In some non-limiting examples, the controller 142, by way of sensors in the pump system 140, can determine when the system is adequately dried to end the drying mode. In some non-limiting examples, the user may initiate an end of the drying mode through the user interface 134. In some cases, drying may occur at ambient temperature, while in other cases, drying may be enhanced by use of heating elements. The heating elements may be integrated into the dispenser 102. For example, the conduits 164 may include heating elements to dispense heated food product. These heating elements can be operated during the drying mode to increase the temperature and increase evaporation of the cleaning solution. Once the drying mode is complete, the user can disconnect the wastewater tube 262 from the dispenser 102.

[0104] Once the drying mode is complete, the dispenser 102 can go into a priming mode, at block 310. In some cases, the dispenser 102 can enter the priming mode based on a user input. In other cases, the dispenser 102 can enter the priming mode automatically following completion of the drying mode. The priming mode ensures that the dispenser 102 is ready to dispense food product when needed. Thus, once in the priming mode, the dispenser 102 waits until the reservoir 122 is attached to the dispenser 102. Once the reservoir 122, with the food product (e.g., sauce) therein, is attached to the dispenser 102, the pump 160 pumps the food product through the pump system 140 in order for the food product to be at the nozzle outlet 152 and ready to serve when the user initiates a dispensing operation. Therefore, the priming mode positions the dispenser 102 to be in a ready state in order to dispense the food product once it is done cleaning. Thus, when the user uses to dispenser 102 to dispense a food product, the food product will come right out and the user will not need to wait for the food product to go through the pump system 140, i.e., the food product will be ready near the nozzle outlet 152 so that the user can receive the necessary food product immediately. Such arrangements also allow for increased accuracy in the amount of food product being dispensed.

[0105] In some non-limiting examples, one or more sensors 126 (e.g., flow sensors, refill sensors, pressure sensors, reservoir sensors) may be positioned on the dispenser 102 so that the dispenser 102, via the controller 142, can determine when the reservoir 122 is attached to the dispenser 102. The dispenser 102 can stay in the priming mode until the reservoir 122 is attached.Once the reservoir 122 is attached, the controller 142 can operate the pump 160 so that the food product is pumped through the pump system 140 to be in a ready to use state. The controller 142 can pump the food product for priming for a predetermined amount of time, a number of pump cycles (e.g., rotations), or based on input from a sensor that may indicate when food product is at the nozzle outlet 152. The priming mode can then end once the food product is in a ready to use state. At this time, the dispenser can be used to dispense food product accordingly. In some nonlimiting examples, the user can initiate an end of the priming mode through the user interface 134. Further, in some non-limiting examples, the wastewater tube 262 can stay attached to the dispenser 102 while the dispenser is in the priming mode in order to catch any food product that exits the nozzle outlet 152 during this mode.

[0106] During the priming mode or after the priming mode, in block 312, the portable cleaning system 200 can be disconnected from the dispenser 102. In other words, the user can disconnect the wastewater tube 262 from the dispenser 102. In some non-limiting examples, the user can disconnect the wastewater tube 262 from the dispenser 102 after the drying mode is done. Once the wastewater tube 262 and the sanitizer tube 242 are disconnected, the portable cleaning system 200 can be moved away from the dispenser 102 to clean other dispensers 102 or to be stored for a future use. Before storage and / or before cleaning other dispensers 102, the wastewater tank 222 can be emptied by way of the exit valve 280 and / or the cleaning pump system 224.

[0107] In some non-limiting examples, the portable cleaning system 200 can aid in a full rinse, wash, sanitize, and rise on the dispensers 102. Therefore, in some non-limiting examples, the portable cleaning system 200 can be connected to a water line or include a water tank thereon to assist with the cleaning of the dispensers 102. Further, in some non-limiting examples, the portable cleaning system 200 can include a pump (e.g., pump system 224) that cycles the cleaning solution through the dispensers 102. Therefore, in such an example, the pump 160 in the dispensers 102 does not need to direct the flow through the dispensers 102.

[0108] As discussed above, the portable cleaning system 200 can be used to clean multiple dispensers 102 at once. Therefore, in some non-limiting examples, multiple dispensers 102 can be lined up adjacent to each other (like the orientation in FIG. 1 or lined up in a linear row) and the portable cleaning system 200 can be moved to a location near the dispensers 102. Each of the dispensers 102 can receive a sanitizer tube 242 and a wastewater tube 262. Therefore, the sanitizertank 220 and the wastewater tank 222 can be connected to all of the dispensers 102. Then, each of the dispensers 102 may go through a cleaning mode as discussed above with process 300. Each of the dispensers 102 can also go through the drying mode and priming mode as discussed above with respect to the process 300. Once the cleaning, drying, and / or priming modes are done, the portable cleaning system 200 can be disconnected and / or moved. Thus, the portable cleaning system 200 can be used to easily and efficiently clean multiple dispensers 102 at one time. This eliminates the need to individually clean each of the dispensers 102 since multiple dispensers 102 can be cleaned at once. In some non-limiting examples, two, three, four, five, six, seven, eight, nine, or ten, or more dispensers 102 can be cleaned at once. Therefore, the number of dispensers 102 that can be cleaned at once depends on the amount of quick connect fittings 240 on the sanitizer tank 220 and wastewater quick connect fittings 260 on the wastewater tank 222.

[0109] In some non-limiting embodiments, all of the dispensers 102 can be linked together via a wired or wireless network, e.g., Bluetooth®, WIFI, etc. Once linked together, the user can use a single user interface 134 on one of the dispensers 102 to control the cleaning process on all of the other dispensers 102. For example, once the portable cleaning system 200 is connected to all of the dispensers 102 by way of the tubes 242, 262, the user can initiate the cleaning mode on just one of the dispensers 102 and all of the dispensers 102 connected will begin the cleaning mode at the same time. This limits the need for the user to select the cleaning mode on all of the dispensers 102 individually. Further, in some non-limiting examples, the user can initiate the cleaning mode on all of the dispensers 102 through a third-party device, e.g., a smart phone or computer. A cleaning mode may also be initiated by a kitchen management system.

[0110] As noted herein, the portable cleaning system 200 is illustrated with the dispenser 102. However, it is contemplated that the portable cleaning system 200 can be used with any type of dispensing system and is not limited to just being used with the dispenser 102 illustrated in FIGS. 1 -4. Therefore, the portable cleaning system 200 can be used to clean any type of dispensing system. In some non-limiting examples, the portable cleaning system 200 can clean sauce dispensers, ice cream dispensers, food dispensers, condiment dispensers, coffee dispensers, drink dispensers, slushie dispensers, fluid dispensers, extruders, and the like. Further, in some nonlimiting examples, the portable cleaning system 200 can clean different types of dispensers at the same time. Therefore, the same type of dispenser, e.g., the dispenser 102, does not need to be usedat the same time for cleaning. Thus, for example, a sauce dispenser, an ice cream dispenser, and a condiment dispenser can be cleaned at the same time by the portable cleaning system 200, i.e., all of the dispensers do not need to be the same type during use.[0U1] In other examples, a cleaning system can be configured differently. For example, FIGS. 6-15 illustrate another example of a cleaning system 400, configured as a portable cleaning cart. As will be appreciated, the cleaning system 400 is similar to the cleaning system 200, with like reference numerals indicating like features using the “400” series of reference numerals. Accordingly, the description of the cleaning system 200 above also applies to the cleaning system 400, unless indicated otherwise.

[0112] The cleaning system 400 includes a cart 410 having a base 408 that is supported on wheels 412 to allow the cart 410 to be moved to a location for cleaning. The base 408 includes a bottom wall 432 (e.g., bottom shelf) and a first sidewall 433 and a second sidewall 435 extending upwardly from the bottom wall 432. One or both of the first sidewall 433 and the second sidewall 435 can define handles for a user to engage with the cart 410. A receiving space 427 is defined between the first sidewall 433 and the second sidewall 435 to allow a plurality of tanks 419 to be removably supported on the bottom wall 432. The bottom wall 432 can be correspondingly shaped to receive each of the plurality of tanks 419. In this way the bottom wall 432 can support the plurality of tanks 419 so that they remain in an upright position. In this case, cleaning system 400 includes three tanks that are received by the cart 410, namely, a sanitizer tank 420, a clean water tank 421, and a wastewater tank 422. In other applications, additional or fewer tanks may be provided.

[0113] The sanitizer tank 420 and the clean water tank 421 can include one or more fittings 440 to allow corresponding tubes (e.g., tubes 242) to be coupled between a dispensing system (e.g., dispensing system 100) and each of the sanitizer tank 420 and the clean water tank 421 for a cleaning operation. The wastewater tank 422 can include an exit nozzle 480 at the bottom of the wastewater tank 422 to allow wastewater to be emptied into a drain. In this case, the exit nozzle 480 is positioned along a bottom of the wastewater tank 422 to allow for emptying into a floor drain. The bottom wall 432 of the cart 410 includes a cutout 481 to accommodate the exit nozzle 480. In other examples, the exit nozzle 480 can be arranged differently. In some cases, the bottom wall 432 can include drain holes 483 to allow spilled liquids from the tanks 419 to drain.

[0114] In some cases, some or all of the plurality of tanks 419 can include an inlet to allow a tank to be filled with a fluid. For example, the sanitizer tank 420 and the clean water tank 421 each include an inlet 471 that can be used to fill the tanks with a corresponding fluid (e.g., clean water or a sanitizing liquid). Additionally, the wastewater tank 422 can include an inlet 471 to allow one or more wastewater tubes (e.g., wastewater tubes 262) to be inserted therein so that the wastewater tank 422 collects the wastewater from a cleaning operation. In some cases, a tank inlet or a cart can be configured to allow for access to the inlet without having to remove the tank form the cart. For example, the inlet 471 for each of the tanks 419 is provided along a top side of the tank 419 for easy accessibility. In other examples, inlets may be provided on the sides of tanks.

[0115] In some examples, a cart can include a cover (e.g., a lid or top shelf) that removably couples to a base to secure tanks therein. In the illustrated example, the cart 410 includes a cover 490 can be placed over the tank 419 to secure the tanks 419 on the base 408. In this way, the cover 490 can also form a top shelf 430 for the cart 410. The cover 490 can include a recessed area 492 to allow for objects to be placed thereon. The cover 490 can removably couple to each of the first sidewall 433 and the second sidewall 435. In this case, the cover 490 include cutouts 494 (e.g., notches) that are configured to receive corresponding protrusions 495 on each of the first sidewall 433 and the second sidewall 435. This arrangement can both locate the cover 490 on the cart 410 and prevent the cover 490 from sliding off or otherwise unintentionally disengaging from the cart 410. In some cases, the cover 490 may be attached to the cart 410 in other ways, for example, via a hinge, latch, snap-fit connection, etc. In some cases, the cover 490 can further include openings 496 to allow for access to the inlets 471 of the tanks 419. In this case, the openings 496 are configured to allow the inlets 471 to extend through the cover 490. In some cases, the inlets 471 can be selectively opened and closed by caps 472. The caps 472 can be vented or unvented.

[0116] In some examples, a cleaning system can include hooks to allow tubing or other cleaning supplies to be stored on the cart. In the illustrated example, hooks 498 are provided on each of the tanks 419 for hanging of corresponding tubes (e.g., tubes 242, 262). In other examples, hooks can be provided elsewhere, such as on the cover 490, the first sidewall 433, or the second sidewall 435.

[0117] In other examples, a cleaning system can be configured differently. For example, FIGS. 16-28 illustrate another example of a cleaning system 500, configured as a portable cleaning- 21 -cart. As will be appreciated, the cleaning system 500 is similar to the cleaning system 400, with like reference numerals indicating like features using the “500” series of reference numerals. Accordingly, the description of the cleaning systems, 220, 400 above also applies to the cleaning system 400, unless indicated otherwise. For example, the cleaning system 500 includes a cart 510 that is supported by wheels 512. The cart 510 has a base 508 coupled to the wheels 512, and a first sidewall 533 and a second sidewall 535 that extend from the base 508.

[0118] In some cases, it may be beneficial to have a cleaning system that is configured to clean multiple dispensers (e.g., dispensers 102) at a time. For example, there can be a plurality of tubes (e.g., tubes 242, 262) with each tube configured to couple between a corresponding dispenser and the cleaning system (e.g., tanks thereof). For example, to clean four dispensers at a time, there can be at least eight tubes (e.g., tubes 242, 262). In some cases, there can be at least three sets of tubes that correspond to a single dispenser and the cleaning system (e.g., tubes 242, 262, a clean water tube 543). In this example, to clean four dispensers at a time, there can be at least twelve tubes. To reduce tangling or kinking of the tubing, the cart can include control structures (organizing structures) that help to control tube placement and allow for easy extension and retraction of the tubing. For example, a cart can include a cover having a plurality of apertures to allow tubing to go through to allow for easier organization and handling of the tubes.

[0119] As shown in FIGS. 16-28, the cleaning system 500 can be configured to operate (e.g., clean) on multiple dispensers at once. Here, the cleaning system 500 is configured to clean up to seven dispensers at a time. However, as mentioned above, the cleaning systems according to the disclosure can be configured to clean a different number of dispensers

[0120] Correspondingly, the cart 510 defines a receiving space 527 receives a plurality of tanks 519 to be removably supported on a bottom wall 532 of the base 508. In this case, the cleaning system 500 includes three tanks that are received in the cart 510, namely, a sanitizer tank 520, a clean water tank 521, and a wastewater tank 522. In other applications, additional or fewer tanks may be provided. Each tank has a volume. For example, the wastewater tank 522 has a volume VI, the sanitizer tank 520 has a volume V2, and the clean water tank 521 has a volume V3. In some cases, the volume VI of the wastewater tank 522 has a ratio of about 2: 1 : 1 to the volume V2 of the sanitizer tank 520 and the volume V3 and the clean water tank 521. In some cases, the volumes V2 and V3 are selected so that the wastewater tank 522 can accommodate allthe liquid from the tanks 520 and 521, plus have excess volume to accommodate any food product in the dispensers 102. For example, the volume VI of the waste water tank 522 has a ratio of 18:8:8 to the volume V2 and V3 of the sanitizer tank 520 and the clean water tank 521.

[0121] The cleaning system 500 includes a cover 590 that acts as a top shelf 530. The cover 290 can removably couple to the base 508 to secure the plurality of tanks 519 within the receiving space 527. Protrusions 595 on the base 508 receive cutouts 594 (e.g., notches) to secure the cover 590 to the cart 510. The first sidewall 533 and the second sidewall 535 can be at a height Hl and H2, respectively. A handle 544 is provided at the second sidewall 535 for a user to push the cart 510. The handle 544 defines a height H3 from the cover 590 to allow a user to grip their hand around the handle 544 to push the cart 510.

[0122] Inlets 571 of the sanitizer tank 520 and the clean water tank 521 are below the cover 590 and the inlet 571 of the wastewater tank 522 is above the cover 590. The inlets 571 of the sanitizer tank 520 and the clean water tank 521 are below the cover 590 to accommodate a recessed area 592. The recessed area 592 allows for objects (e.g., reservoirs or covers of a dispenser being cleaned) to placed therein. For example, multiple cleaning bottles can be placed within the recessed area 592.

[0123] One or more fittings 540 or inlets 571 of the sanitizer tank 520 and the clean water tank 521 can allow corresponding tubes (e.g., tubes 242, 543) to be coupled between a dispensing system (e.g., dispensing system 100) and each of the sanitizer tank 520 and the clean water tank 521 for a cleaning operation. For example, the inlets 571 of the sanitizer tank 520 and the clean water tank 521 include seven fittings 540. In some cases, the inlets 571 can include more or fewer than seven fittings 540.

[0124] The cover 590 includes an opening 596 to receive the inlet 571 of the wastewater tank 522. In some cases, the inlet 571 of the wastewater tank 522 can be below the cover 590. In some cases, the inlet 571 of the wastewater tank 522 can be positioned on a side of the wastewater tank 522. Additionally, the wastewater tank 522 includes an exit nozzle 580 to drain the waste into a floor drain after the user is done cleaning the dispensers 102.

[0125] A cover for a cleaning system can include a plurality of apertures for tubes to be inserted through a top cover to connect with a tank in a receiving area of a cart. The apertures can function to organize the tubes and retain the tubes at a top surface of the cleaning cart to makeaccess easier for a user. For example, the cleaning system 500 includes the cover 590 that defines a plurality of apertures 597. The plurality of apertures 597 receive tubes from the plurality of tanks 519. For example, there are fourteen apertures 597 that receive seven tubes from the sanitizer tank 520 and seven tubes from the clean water tank 521. In some cases, the cover 590 can include more or fewer than fourteen apertures 597.

[0126] A cleaning cart can include a retraction system for tubes that are connected to plurality of tanks. For example, a spring mechanism can automatically retract the tube. While the user unwinds the tube, the spring accumulates tension. A ratcheting feature can allow the tube to stay at the length it was pulled to. Once the user removes the tube from the dispensing system, the tension can be released, and the tube is automatically recoiled back onto the reel. In another example, weights can be added to the tubes. The weight allows the tube to extend and retract back into the reel. In other examples, a coil return mechanism can be used to allow a tube to extend and retract to its original shape. Referring to FIG. 16, the cleaning system 500 includes a retraction system 598 for the sanitizer tank 520. The tube 543 is connected to a fitting 540 of the sanitizer tank 520. In some examples, the retraction system 598 can be only for one set of tubes (e.g., 242, 262, or 543) that is connected to the sanitizer tank 520, clean water tank 521, or wastewater tank 522. In some examples, the retraction system 598 can be for two set of tubes (e.g., 242, 262 or 242, 543, or 262, 543). In some examples, the retraction system 598 can be for three set of tubes (e.g., 242, 262, 542). A retraction system can be configured in different arrangements for a cleaning cart. For example, the retraction system 598 is shown at the one or more fittings 540 (see FIG. 16). In some examples, the retraction system 598 can be directly mounted to the cart 510 via fasteners.

[0127] In other examples, other types of retractions systems can be used. For example, in some cases, the retraction system 598 can be configured as a weight. The weight can be attached to a tube (e.g., tube 543) between the cover 590 and the fittings 540. Under the influence of gravity, the mass of the weight can cause the tube to retract into the receiving space 527.

[0128] The retraction system 598 or the cover 590 (e.g., the aperture 597 thereof) help to guide the tubes 242, 262, and 543 during extension and retraction to prevent tangles.

[0129] In some cases, a stop can be provided to prevent a tub from being pulled through an aperture in a cover, as can ensure easy access to the tube by a user. As illustrated in FIG. 16,an example stop 591 (e.g., a fitting, quick-connect, collar, etc.) is coupled at a free end of the tube 543. The stop 591 is sized to be larger than the aperture 597 to prevent the tube 543 to be pulled through the retraction system 598. For example, the retraction system 598 for the tube 262 that is connected to the inlet 571 of the wastewater tank 522 includes the stop 591 on the tube 262 to prevent the tube 262 to be pulled through the retraction system 598.

[0130] A retraction system can be configured differently for other tanks. For example, the retraction system 598 is between the one or more fittings 540 of the clean water tank 521 and the cover 590. Similarly, the retraction system 598 can be between the one or more fittings 540 of the sanitizer tank and the cover 590. In these examples, the stop 591 on the tube (e.g., tubes 242, 543) prevents the tube from falling through the apertures 597 on the cover 590.

[0131] A pump system in a dispenser can aid in cleaning the dispenser by pumping fluid (e.g., sanitizer, water, etc.) therein. An auxiliary pump on a cleaning cart can also be provided to pump fluid from a plurality of tanks and throughout the dispenser. For example, in addition to the pump system 140, an auxiliary pump 599 (see FIG. 24) on the cleaning system 500 is provided to push fluid up through the tubes connected to the sanitizer tank 520 and the clean water tank 521 to the dispenser 102.

[0132] In other examples, a cover for a cleaning system can be configured differently. For example, FIG. 30 illustrates another example of a cover 690. As will be appreciated, the cover 690 is similar to the cover 290, 490 and 590, with like reference numerals indicating like features using the “600” series of reference numerals. Accordingly, the description of the cleaning system 200, 400, and 500 above also applies to the cover 690, unless indicated otherwise.

[0133] Referring to FIG. 31, the cover 690 is configured as a top shelf 630. The cover 690 includes cutout 694 to secure the cover 690 to a cart (e.g., cart 210, 410, 510). The cover 690 includes an opening 696 to allow the sanitizer tank 520, clean water tank 521 , and wastewater tank 522 to extend through the opening 696. For example, the inlets 571 of the sanitizer tank 520, clean water tank 521, and the wastewater tank 522 can be above the cover 690. In some cases, the opening can further receive a container to hold reservoirs or other components, in a manner similar to the recessed area 592. Additionally, as mentioned above the number of apertures 697 can be different to accommodate tubing for a desired dispensing system. As shown in FIG. 20, the cover 690 includes twenty-eight apertures 697.

[0134] In other examples, a cleaning system can be configured differently. For example, FIGS. 16-28 illustrate another example of a cleaning system 700, configured as a portable cleaning cart. As will be appreciated, the cleaning system 700 is similar to the cleaning system 400, with like reference numerals indicating like features using the “700” series of reference numerals. Accordingly, the description of the cleaning systems, 220, 400, 500, 600 above also applies to the cleaning system 700, unless indicated otherwise. For example, the cleaning system 700 includes a cart 710 that is supported by wheels 712. The cart 710 has a base 708 coupled to the wheels 712, and a first sidewall 733 and a second sidewall 735 that extend from the base 708.

[0135] The cleaning cart 700 is similar to the previously described cleaning carts 200, 300, 400, 500, and 600, but utilizes the wastewater tank 722 as the first sidewall 733. This configuration may allow for a more compact overall design while maintaining the functionality of the cleaning system. The receiving space 727 is defined between the wastewater tank 722 and the second sidewall 735, creating an area where the sanitizer tank 720 and clean water tank 721 can be positioned. This arrangement may optimize the use of space within the cart 710 while still providing easy access to all tanks.

[0136] In this configuration, the wastewater tank 722 includes a protrusion 734 that extends from a surface that defines the inlet 771 to the wastewater tank 722. The protrusion 734 extends a width of the wastewater tank 722. This protrusion 734 provides a secure connection point for supporting the top shelf 730. Correspondingly, the top shelf 730 is supported by both the protrusion 734 of the wastewater tank 722 and the second sidewall 735, which may enhance the stability of the top shelf 730 and provide a sturdy surface for placing items or organizing cleaning supplies.

[0137] The base 708 of the cleaning cart 700 includes a cutout 781 at one end, which accommodates the exit nozzle 780 of the wastewater tank 722. This design feature may allow for easy drainage of the wastewater tank 722 without the need to remove it from the cart 710. The positioning of the exit nozzle 780 within the cutout 781 may also protect it from damage during transport and provide a clear path for connecting drainage hoses when needed.

[0138] Additionally, the base 708 of the cleaning cart 700 defines a pair of drain holes 783. These drain holes 783 may serve multiple purposes, such as allowing any spilled liquids to drain away from the cart 710, preventing pooling of water or cleaning solutions, and facilitating easiercleaning and maintenance of the cart 710 itself. The inclusion of these drain holes 783 may contribute to the overall hygiene and functionality of the cleaning system, ensuring that the cleaning cart 700 remains clean and dry during use and storage.

[0139] The description of the different advantageous embodiments has been presented for purposes of illustration and description and is not intended to be exhaustive or limited to the embodiments in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. Further, different advantageous embodiments may provide different advantages as compared to other advantageous embodiments. The embodiment or embodiments selected are chosen and described in order to best explain the principles of the embodiments, the practical application, and to enable others of ordinary skill in the art to understand the disclosure for various embodiments with various modifications as are suited to the particular use contemplated.
