The present invention relates to beverage dispensers, and in particular to the cleaning of beverage dispensers and to the providing of a clean environment for a beverage dispenser. Specifically, a method and apparatus are disclosed for cleaning a dispenser which dispenses beverages and for maintaining the beverage dispenser in a clean environment.
Restaurants, bars, and other types of food establishments use a dispenser in order to dispense beverages.
Dispenser 100 is coupled to a plurality of different beverages (or beverage ingredients) via inlet hose 102. Within inlet hose 102, a plurality of tubes (not shown) receive beverages (or beverage ingredients) from different sources. For example, one of the tubes within inlet hose 102 may be connected to a water source so that water can be dispensed from dispenser 100. Another tube within inlet hose 102 may be connected to a source of carbonated water. Other tubes within inlet hose 102 may be connected to containers storing concentrated beverage ingredients (e.g. concentrated soda flavorings). Dispenser 100 may mix one of the beverage ingredients with carbonated water to produce various types of flavored sodas (for example).
Pushbuttons 108 thus each correspond to various beverages such as water, carbonated water, or various flavored sodas. If pushbutton 108 corresponding to water or carbonated water is depressed, then water or carbonated water is dispensed through nozzle 106. If pushbutton 108 corresponding to a flavored soda is depressed, then concentrated soda flavoring and carbonated water are mixed within dispenser 100 and dispensed through nozzle 106. An exemplary dispenser is manufactured by Wunder-bar. A further exemplary dispenser is disclosed in Schroeder, U.S. Pat. No. 7,658,006, which is hereby incorporated by reference in its entirety.
At least some of the concentrated soda flavorings received by dispenser 100 include corn syrup as a sweetener. Thus, as various flavored sodas and/or other beverages are dispensed from nozzle 106, a residue which may include corn syrup remains on various surfaces of nozzle 106. Over time, the residue builds and nozzle 106 becomes unsanitary.
Also, the soda flavorings (and/or residue from the soda flavorings or other beverages) accumulate in a drain that is used to catch soda flavorings that are dispensed by dispenser 100 and that do not enter a glass or cup. For example, when dispenser 100 is resting on a holster when not in use, fluids will typically drip out of nozzle 106 and will flow down a drain. As the flavorings and/or residue flow down the drain, they will sometimes remain on drain surfaces. Consequently, fruit flies are attracted to the drain, multiply, and create an unhealthy environment. If not addressed, the fruit flies will fly out of the drain and into the area where the nozzle rests when not in use (e.g. in a holster). This is undesirable for a restaurant and/or bar venue. The resulting multitude of fruit flies is unclean, unhealthy, and is significantly disliked by both employees and customers. Presence of fruit flies in a bar and/or restaurant may result in reduced customers, reduced profits, and bad social media reviews.
Restaurants, bars, and other types of food establishments use a dispenser in order to dispense beverages.
Dispenser unit 50 is coupled to a plurality of different beverages (or beverage ingredients) via respective hoses. For example, one hose may be connected to a water source so that one dispenser 1100 can dispense water. Another hose may be connected to a source of carbonated water. Other hoses may be connected to containers storing concentrated beverage ingredients (e.g. concentrated soda flavorings). Each dispenser 100 may mix one of the beverage ingredients with carbonated water to produce various types of flavored sodas (for example).
Each dispenser 1100 may correspond to various beverages such as water, carbonated water, or various flavored sodas. Each dispenser may be labeled with the respective beverage that is dispenses. Each dispenser may include an actuator arm 1107 that controls a respective actuator. When an actuator arm 1107 is pushed backwards (by being pushed, for example, with a cup or glass), the beverage corresponding to the pushed actuator arm is dispensed. Each dispenser includes a respective nozzle from which the dispenser's respective beverage is dispensed. Pushing the actuator arm 1107 on a dispenser causes a beverage to be dispensed from that dispenser's respective nozzle 1106. If actuator arm 1107 corresponding to water or carbonated water is depressed, then water or carbonated water is dispensed through nozzle 1106. If actuator arm 1107 corresponding to a flavored soda is depressed, then concentrated soda flavoring and carbonated water are mixed within dispenser 1100 and dispensed through nozzle 1106. An exemplary dispenser is disclosed in U.S. Pat. No. 5,381,926, which is hereby incorporated by reference in its entirety.
Other prior art beverage dispensers use push buttons instead of actuator arm in order to dispense beverages. A cup is placed under nozzle 1106, the push button is pushed, and the beverage is dispensed into the cup.
At least some of the concentrated soda flavorings received by dispenser 1100 include corn syrup as a sweetener. Thus, as various flavored sodas are dispensed from nozzle 1106, a residue which includes corn syrup remains on various surfaces of nozzle 1106. Over time, the residue builds and nozzle 1106 becomes unsanitary.
A method of delivering insecticide comprises the steps of providing an insecticide in a container, allowing the insecticide to flow out of the container, and allowing the insecticide to flow into a drain beginning downstream of an opening in said drain.
A method and apparatus cleans a plurality of beverage dispensers which are located within a dispenser unit. A plurality of arms are rotatable with reference to beverage dispensers, respectively, so that a cleaning nozzle attached to each arm is situated under a respective dispenser nozzle. The cleaning nozzles are oriented to spray cleaning solution towards respective dispenser nozzles. At least one fluid valve and/or pump alternatively permits and blocks a cleaning solution to flow to the nozzles, respectively. A power supply provides flow signals to the at least one fluid valve and/or pump, respectively, wherein the valve(s) and/or pump transitions between permitting and not permitting flow of cleaning solution responsive to transitioning of the flow signals, respectively. A transmitter signals the power supply to transition the flow signals to cause the fluid valve(s) and/or pump to permit the cleaning solution to flow to the cleaning nozzles.
As shown in
During use, and as previously described, beverages flow out of dispenser 100 (and are thus discharged through nozzle 106) based on which pushbutton 108 is depressed. Some beverages, however, flow down drain 310 when dispenser 100 is inserted into holster 200 after a beverage has been dispensed (and while discharge from nozzle 106 is still occurring). After a period of time, small quantities of the beverages that have been dispensed from dispenser 100 will accumulate within drain 310. The beverages that have been dispensed from dispenser 100 typically include corn syrup. Various types of insects, such as fruit flies, are often attracted to corn syrup. Thus, fruit flies will typically accumulate and breed within drain 310.
As previously described, as the fruit flies continue to breed and accumulate within drain 310, fruit flies will eventually fly out of drain 310 and to the location where drain 310 is connected to holster 200. The fruit flies will fly out of holster 200 and will begin to fly around the bar and/or restaurant area where dispenser 100 is being used. Such an accumulation of fruit flies is disturbing to both customers and employees. Customers that see fruit flies in a bar and/or restaurant establishment may not return in the future. Thus, the accumulation of fruit flies in the area where dispenser 100 is being used is undesirable.
In accordance with an exemplary embodiment of the present invention, container 302 is included. Container 302 includes a chemical or solution 312 that eliminates insects such as fruit flies. Solution 312 may therefore be what is known as an insecticide, namely a substance that kills insects. A small opening may be found at the bottom of container 302 so that solution 312 that is stored in container 302 and that eliminates fruit flies slowly enters drain 310. As shown, support member 306 is coupled to holster 200. Container 302 sits within support members 303, 306 with the opening of container 302 facing downwards, in the direction of gravity. Solution 312 slowly flows out of container 302, through drain tube 314, and into drain 310 at secondary drain opening 316. While beverages dispensed from dispenser 100 (or having a residual amount dripping out of dispenser 100) first enter drain 310 at the point where holster outlet 204 meets drain 310, solution 312 is first introduced into drain 310 at a location past the point where holster outlet 204 and drain 310 meet. That location past the point where holster outlet 204 and drain 310 meet is considered to be “downstream” from holster outlet 204. In particular, residue and/or waste moves downstream as follows through drain 310. Downstream flow through drain 310 normally occurs under the force of gravity, although it may be accomplished with a pump (or suction) as well. Thus, solution 312 first enters drain 310 downstream of where fluid or residue exiting nozzle 106 first enters drain 310. As solution 312 slowly drips into drain 310, any fruit flies resident within drain 310 are eliminated.
Depending on the composition of solution 312, solution 312 may be used against insect eggs and larvae. With regard to fruit flies, solution 312 may be used against, for example, fruit fly eggs. In an exemplary embodiment of the present invention, solution 312 is Permethrin. Permethrin is one example of the insecticide that may be used for solution 312. It is understood, however, that other insecticides may be used in place of, or in addition to permethrin. Exemplary other insecticides that may be used within solution 312 include, for example, Methoprene, Pyrethrin, and Pyrethrum. Again, these are merely exemplary as other insecticides may also be used for solution 312.
Solution 312 slowly drips out of container 302. Thus, at regular intervals (for example), container 302 is regularly refilled with insecticide so that elimination of fruit flies, and other insects, in drain 310 may occur on a continuous basis.
In one exemplary embodiment of the present invention, solution 312 is poured into container 302, and from there, solution 312 enter drain 310. Container 302 can be refilled at any desired time, including when container 302 is empty. In particular, container 302 can be removed from support members 303, 306, refilled with solution 312, and then reinserted into position by support members 303, 306. There are various ways to determine when container 302 may be refilled. In one embodiment, container 302 is refilled on a regular basis (e.g. daily, weekly, etc.). In another embodiment, container 302 is refilled when the level of solution 312 in container 302 has dropped below a certain level (which can be observed through visual inspection or measured using, for example, an electronic sensor). In a further exemplary embodiment of the present invention, an opening is accessible to the interior of container 302 so that container 302 can be filled with solution 312 while remaining in place by support members 303, 306.
As further illustrated in
In
Thus, in accordance with the embodiments described above, fluid tube 313 may be situated below container 302. In a further exemplary embodiment, fluid tube 313 may be situated on either side of container 302. In yet a further exemplary embodiment of the present invention, fluid tube 313 may be situated above container 302.
In the exemplary embodiments described above, solution 312 may flow into drain 310 via gravity. It is understood, however, that solution 312 may be introduced into drain 310 through the use of other mechanisms, such as a pump. An exemplary pump can be powered through various means including, for example, electricity.
Container 302 has been described an illustrated as being attached to, or coupled to holster 200, however this is merely exemplary. In a further exemplary embodiment of the present invention, container 302 is not attached to holster 200 but is instead in a location that is not in contact with holster 200.
In one exemplary embodiment, the solution/fluid that flows through fluid tube 313 is water. It is understood, however, that other types of solutions may be used as well. Desirable solutions are solutions that are safe for human consumption. Thus, a food grade solution is desirable.
Exemplary food grade solutions include chlorine bleach (diluted), hydrogen peroxide (3%), and white distilled vinegar (5%). As explained in U.S. patent application Ser. No. 14/935,664, other solutions may be used as well. The solution flowing through fluid tube 313 does so under pressure. Pressure can be supplied by a municipal water source or by a pump. Such a pump is described, and exemplary control thereof is described in U.S. patent application Ser. No. 14/935,664
As previously explained, beverage dispenser 100 normally sits within holster 200 when not in use. A top view of an exemplary holster is shown in
During actual operation, nozzle 106 of dispenser 100 is inserted into holster 200 via holster opening 205. In this manner, nozzle 106 directly faces the opening of elbow member 230 that is projecting upwards within compartment 201. A cleaning solution is allowed to flow into holster inlet 206. The cleaning solution then flows through elbow member 230 and exits elbow member 230 at a top opening thereof. The cleaning solution (fluid), under pressure, continues to rise within compartment 201 until it reaches nozzle 106. The cleaning solution continues to be sprayed onto nozzle 106 for a predetermined amount of time, and then flow of the cleaning solution is terminated. As the fluid cleans nozzle 106, the fluid then drops under the force of gravity to the bottom of compartment 201. The fluid then exits compartment 201 via holster outlet 204. The fluid can then be coupled to a municipal drain or to a storage container for later reuse, recycling, or to be discarded.
In a further exemplary embodiment of the present invention, cleaning solution is introduced into compartment 201 at another location before making contact with nozzle 106. For example, cleaning solution may be introduced into compartment 201 at a location that is above holster outlet 204. As the cleaning solution is under pressure, the cleaning solution will again be sprayed upwards and make contact with nozzle 106 before falling under gravity and exiting holster 200 via holster outlet 204.
The previous explanation has described the use of a pump to spray cleaning solution towards nozzle 106 under pressure, although the use of a pump may be optional depending upon the source of the cleaning solution. For example, if the cleaning solution is water that is obtained from a public water source, the water will be pumped under pressure and the water will thus enter elbow member (or enter into interior 201) under pressure. A typical public water source will provide water at a pressure of 40 pounds per square inch (psi), and at that pressure the pressure is sufficient to spray water into up to four holsters 200 simultaneously (and to thus clean four nozzles 106 simultaneously). In other words, a minimum of 10 psi of cleaning solution per nozzle 106 is desirable. In such an exemplary embodiment, a valve and solenoid may be used to simply apply the pressurized water to multiple holsters 200. In such an embodiment, once pressurized water flows through a solenoid operated valve, the water is directed through y-connections (for example) so that it is simultaneously applied to multiple holsters 200 (and to clean multiple nozzles 106). To direct the water (or other cleaning solution) at more than four holsters, the use of a pump in order to increase water (or other cleaning solution) pressure is desirable.
The use of elbow member 230 is merely exemplary. Other mechanisms may be used for spraying cleaning solution into nozzle 106, such as is described in U.S. patent application Ser. No. 14/935,664.
In a further exemplary embodiment, a light is included to illuminate container 302. In this manner, it can be readily seen that a method and/or apparatus is in place to control insects such as fruit flies. Being able to see that container 302 is in place may be comforting to customers and employees. Such lighting may also arouse interest to a prospective purchaser.
The holster described above may be used in combination with the method and/or apparatus for cleaning beverage dispensers that is described in U.S. patent application Ser. No. 14/935,664. It is understood, however, that the method and/or apparatus described in Ser. No. 14/935,664 is merely exemplary, and the holster described above may be used in combination with other apparatuses and/or methods.
Over time, as dispensers 1100 are used, residue builds on surfaces of nozzles 106, and that residue may have adverse consequences. Bacteria and/or mold may grow on the residue. The residue may attract insects such as fruit flies. When beverages are contaminated with bacteria, mold or insects, the beverages can cause sickness and disease. Furthermore, the taste of the beverage being dispensed through the residue may be adversely affected. The residue can block beverages flowing through nozzle 1106, thus reducing the flow rate of beverages being dispensed. This may increase the amount of time needed to dispense beverages. Residue creating a blockage within dispenser 1100 can alter the ratio of carbonated water and concentrated soda flavoring which are mixed together, thus causing a flavored soda to be dispensed which has either not enough flavoring or too much flavoring; the result is the dispensing of a beverage which does not have its expected taste. A buildup of debris over time can also shorten equipment life.
The residue which collects on surfaces of nozzles 1106 can thus have numerous consequences, including:
It is thus desirable for each nozzle 1106 to be clean and for any residue which appears on nozzle 1106 to be removed.
In a food service setting, and as shown in
Dispenser unit 50 dispenses beverages by placing a container under the respective nozzle 1106 of a dispenser from which a beverage is desired. In some food service settings, dispenser unit 50 is only available to employees. In that setting, customers tell an employee which beverages they desire and the employee obtains the beverage from the appropriate dispenser 1100. In other food service settings, the beverages are considered “self-serve” and a customer may directly use dispenser unit 50 in order to obtain a desired beverage.
In the configuration shown in
In the position shown in
Again, doors 188 are illustrated in an open position, although they are ordinarily closed when arm 1200 is in the position shown in
In order for each nozzle 1106 to be cleaned, arm 1200 is desirably rotated so that cleaning nozzle 1206 is under dispenser nozzle 1106. Rotation of arm 1200 occurs by moving arm 1200 through a variety of different positions until it is in a position that is desirable for dispenser nozzle 1106 to be cleaned.
As further explained below, the angle at which arm 1200 appears in
In
Arm 1200 continues to be rotated until it is in the 3rd position shown in
The first position shown in
In actual operation, arm 1200 is stored in, for example, the 1st position, and behind doors 188 when dispenser unit 50 is being used for dispensing beverages. Typically, however, there are certain times of the day when dispenser unit 50 is not dispensing beverages. For example, dispenser unit 50 may not be dispensing beverages after the food establishments in which dispenser unit 50 has been closed for the day. At that time, since dispensers 1100 will not be dispensing beverages, nozzles 1106 are desirably cleaned. In one exemplary embodiment of the present invention, optional doors 188 are opened and arm 1200 is rotated until it is in the position shown in
In accordance with a further exemplary embodiment of the present invention, and as shown in
In accordance with a further exemplary embodiment of the present invention, an interlocking mechanism is included to ensure that arm 1200 is in the third position before fluid is permitted to flow out of cleaning nozzle 1206. In this manner, for example, if employees forget to lower arm 1200 into the 3rd position, fluid will not be permitted to flow out of cleaning nozzle 206 while, for example, arm 1200 is in the first position or the second position. The interlocking mechanism can have a variety of different configurations as is known to one of ordinary skill me art. For example, the interlocking mechanism can be a switch that is actuated after arm 1200 is placed into the third position. Such a switch can be included within hinge 1208, situated behind arm 200 when arm 1200 is in the first position, etc.
In the third position, arm 1200 is oriented so that cleaning nozzle 1206 is directly below dispenser nozzle 106. This configuration is shown, for example, in
Dispenser unit 50 desirably includes a drip tray which catches drippings that flow from dispensers 1100. The drip tray may also be used for catching fluid after it has been sprayed into nozzle's 1106.
In many restaurants, dispenser unit 50 includes more than one dispenser 1100. Many restaurants have dispenser unit 50 with multiple dispensers 1100 in order to accommodate the number of customers who wish to be served beverages and the variety of different beverages that customers desire.
Cleaning apparatus 300 shown in
Controller 335 instructs valves 310a,b to open and close via power supply 320. In an exemplary embodiment of the present invention, power supply 320 is a PS-6012 manufactured by Altech Corp. and is installed and operated in accordance with the Altech Corp. PS-60 data sheet which is hereby incorporated by reference.
Controller 335 signals power supply 320 via controller outputs 331a,b. Power supply 320 subsequently provides 12 volt signals to valves 310a, b responsive to being signaled by outputs 331a,b respectively. Thus, a positive signal on controller output 331a causes power supply 320 to transmit a 12 volt signal on power supply output 321a. Furthermore, a positive signal on controller output 331b causes power supply 320 to transmit a 12 volt signal on power supply output 321b. When the positive signal is removed from controller output 331a, output 321a ceases to provide a 12 volt signal. When the positive signal is removed from controller output 331b, output 321b ceases to provide a 12 volt signal.
Valves 310a, b are valves which regulate flow of liquid. In an exemplary embodiment of the present invention, valves 310a, b are 12 VDC solenoid valves (i.e. valves with 12 volt relays) plastic ½″ manufactured by Zilong. When valves 310a,b receive 12 volt signals on their respective control inputs, the valves open and fluid provided at the valves' input is allowed to flow out the valves' output. When the 12 volt signals are removed from each valves' control inputs, the valves close and fluid is not permitted to flow out of each valves' output. A desirable flow rate for the output of each valve is, for example, 1 gallon per minute.
Thus, power supply outputs 321a,b are connected between power supply 320 and valves 310a, b. When power supply 320 places a 12 volt signal on power supply output 321a, valve 310a opens. When power supply 320 places a 12 volt signal on power supply output 321b, valve 310b opens. When the respective 12 volt signals are removed from each respective power supply output, the respective valve closes.
Valves 310a,b receive fluid via valve inlets 311a,b respectively. Valve inlets may be pipes or tubes (e.g. flexible tubes) having, for example, a diameter of ⅜″. Valve inlets 311a,b receive fluid via pressurized fluid source 315. Pressurized fluid source 315 includes branch 316 which directs fluid under pressure to valve inlets 311a,b. Thus, when valve 310a opens, fluid from valve inlet 311a is permitted to flow through valve outlet 312a. Furthermore, when valve 310b opens, fluid from valve inlet 311b is permitted to flow through valve outlet 312b. Valve outlet 312a is connected to inlet 206a and valve outlet 312b is connected to inlet 206b. Thus, when valves 310a,b open, fluid is directed to holsters 200 in order to clean nozzles 106.
Pressurized fluid source 315 delivers pressurized fluid from a pressurized fluid source. The pressurized fluid source can be, for example, pressurized water from a municipal water source. Alternatively, the pressurized fluid source can be otherwise. For example,
The fluid used to clean nozzle 106 may be for example a fluid which is safe for human consumption. Thus, a food grade solution is desirable as the fluid to be stored in tank 410. Exemplary food grade solutions include chlorine bleach (diluted 1 teaspoon to 1 quart of water, hydrogen peroxide (3%), and white distilled vinegar (5%). Other liquids may be used as the fluid within tank 410. Exemplary fluids which may be used within tank 410 include, for example: a) citric acid (with an exemplary concentration of between 2.5% and 35%) b) lactic acid (with an exemplary concentration of between 2.5% and 60%); and c) peracetic acid (with an exemplary concentration of between 1% and 22%). Other food sanitizing surface agents may also be used, including Steramine. Water may also constitute a “fluid.” Furthermore, fluid source 315 may optionally include a y-junction 420 and valves 416, 418 which allows the fluid flowing into pressurized fluid source 315 to alternate between the fluid stored in tank 410 and water obtained from a commercial water supply 430. Controller 335 can thus allow solution from tank 410 to clean nozzle(s) 106 for a first amount of time (by actuating valve 416), and to then allow water from a commercial water source to clean nozzle 106 for a second amount of time (by actuating valve 418).
In a further alternative embodiment of the present invention, tank 410 is eliminated and all cleaning is done simply using fluid from water source 430. Water source 430, may be, for example, a municipal water source. If the municipal water source is supplying water with sufficient pressure, then the pressure provided by the municipal water source may be sufficient to clean nozzle 106.
In a further exemplary embodiment of the present invention, an additional pump 435 is used with the water from water source 430 in order to increase the pressure of water being received from water source 430. Pump 435 may be used, for example, on demand. Thus, for example, a water pressure of 40 PSI from water source 430 may be desirable to clean nozzle 106. Pump 435 may be omitted if the water pressure from water source 430 is approximately 40 PSI or higher, Pump 435 may be included if the water pressure from water source 430 is below 40 PSI. If pump 435 is operated on an on demand basis, the pump 435 is activated if water pressure from water source 430 is below 40 PSI and pump 435 is deactivated (allowing water to pass through without boosting water pressure) if water pressure from water source 430 is 40 PSI or greater. A water pressure of 40 PSI is merely exemplary, and it is understood that a water pressure at which operation of pump 435 is desirable may be higher or lower depending upon individual circumstances.
In a further embodiment of the present invention, pump 435 may be used in combination with a fluid pressure detection switch. Thus, for example, if water pressure from the water source drops below a predetermined limit (e.g. 24 PSI) then the fluid pressure switch detects the lower pressure and activates the pump automatically. Thus, fluid is sprayed towards nozzle 106 without a pump assist if fluid pressure from the fluid source is above 24 PSI (for example) and fluid is sprayed towards nozzle 106 with a pump assist if fluid pressure from the fluid source is below 24 PSI (for example).
Each of the above alternative embodiments enables pressurized fluid from a single source to arrive at pressurized fluid source 315, to flow through branch 316, and to then be sprayed onto multiple nozzles 106 via valve outlets 312a,b.
In accordance with an exemplary embodiment of the present invention, it is desirable to allow fluid to be sprayed out of valve outlets 312a,b at predetermined times. Thus, when a predetermined time is reached (e.g. 4 AM, 8 AM etc.) valves 310a,b are opened and pressurized fluid flows out of valve outlets 312a,b and towards nozzle 106. The predetermined time may be chosen based upon times that beverages are typically not being served from dispenser 100 (such as a when a bar or restaurant is closed). At such times, nozzles 106 are resting in holsters 200 as they are not being used.
In an exemplary embodiment of the present invention, in order to ensure that sufficient pressure is delivered to each nozzle 102, valves 310a, b can be opened sequentially instead of at the same time. Thus, valve 310a can be opened, kept open, and closed before valve 310b is opened, kept open and closed.
While the above exemplary embodiment illustrates controller 335, it is understood that controller 335 can be replaced with other methods and apparatus for controlling cleaning apparatus 300.
For example, controller 335 can be located at a remote site and can communicate with transmitter 330 via a Wi-Fi connection. Thus, a Wi-Fi receiver can receive signals over a wireless connection and can then signal power supply 320 to open and close valves in order to perform nozzle cleaning. It is understood that other forms of communication (wired and wireless) may also be used.
In actual practice, it is desirable for power supply 320 and controller 335 (or a Wi-Fi receiver if power supply 320 is controlled remotely) to be mounted in a box, such as a box with a screw on panel, in order to protect power supply 320 and controller 335 from tampering. Valves 310a and 310b can be mounted, for example, next to such a box and near tank 410 and/or a commercial water supply. The box and valves 310a,b can be located away from the bar area in order to avoid unnecessary crowding of the bar area. Valve outlets 312a,b can be routed through walls and/or floors to be connected to inlet 206. In this manner, power supply 320 and controller 335 can be placed in a desirable location in order to clean a plurality of dispensers 100 located in respectively different physical locations.
In an alternative embodiment of the present invention, the fluid that is flowing through valve outlets 312a,b can be heated. In this manner, effectiveness of the fluid in disinfecting nozzle 106 can be enhanced. A fluid heating mechanism (for example an instant hot water dispenser manufactured by InSinkErator) can be used to heat fluid before it reaches nozzle 106.
Exemplary locations to place an instant hot water dispenser include along valve outlets 312a,b, valve inlets 311a,b, or anywhere before or after valve 416 and/or valve 418.
The above description and illustrations show fluid flowing into two valve outlets 312a,b via branch 316. It is understood, that the description of two valve outlets is merely exemplary, and the actual number of valve outlets may be two or greater. In this manner, two or more cleaning nozzles 206 of respective arms 200 can be included in accordance with the exemplary embodiments set forth above.
The above description describes opening valves and/or engaging a pump for a certain amount of time in order to clean nozzles 1106. One or ordinary skill in the art will recognize that there are methods for determining how much cleaning fluid is sprayed on each nozzle 1106. For example, instead of measuring the amount of time fluid is being sprayed onto nozzles 1106, one can spray cleaning fluid onto nozzles 1106 based on the amount of cleaning fluid being sprayed. Thus, for example, a dosing pump can be used to deliver a certain amount of cleaning fluid to nozzles 1106. Permitting and then stopping cleaning fluid from spraying onto nozzles 1106 can thus be a function of the amount of cleaning fluid sprayed, the amount of time during which cleaning fluid is sprayed, or both.
In a further exemplary embodiment of the present invention, an additional tube is directed towards the drain at which holster 1200 drains. This additional tube can direct a sanitizing solution towards the drain to prevent fruit flies from accumulating near the drain. The sanitizing solution can be permitted to flow into the drain by use of the controller described above, and this sanitizing solution can be permitted to flow into the drain at a predetermined time of day.
In a further exemplary embodiment of the present invention, an electronic memory stores a record of when cleaning fluid is permitted to flow towards nozzle 106 (and optionally for how long). In this manner, a record is maintained to ensure compliance with a regular cleaning schedule.
The method and apparatus described above provides numerous advantages over the prior art:
