Definitions
- This invention relates generally to a dishwasher apparatus, more particularly to a dishwasher apparatus having only one incoming water line and using a pump to circulate water against various additives such as detergent sources and rinse aid sources. Such invention is also designed to save on additives and hot water. Also, the dishwashing apparatus is designed in such a way as to save on space and installation costs.
- the invention also relates to a flip-top detergent dispenser, designed to hold a particularly shaped detergent container.
- Said flip-top detergent dispenser is designed in such a manner as to facilitate the safe and convenient insertion and removal of the particularly shaped detergent container into the flip-top detergent dispenser.
- Said flip-top detergent dispenser is designed only to operate with the particularly shaped detergent container, thus preventing the use of an incompatible and unsafe product in said dishwasher apparatus.
- Dishwashing apparatuses which make use of solid dishwashing additives such as a solid detergent source and a solid rinse aid source are known in the art.
- water is directed onto each of the solid additives in order to form additive solutions which can be circulated throughout the machine.
- dishwashing apparatuses of the prior art have typically utilized three separate outside waterlines.
- One waterline served to fill the machine with clean hot water.
- the other two waterlines directed water through two separate product nozzles onto a solid detergent source and a solid rinse aid source respectively, in order to form a detergent solution and a rinse aid solution.
- the solid rinse aid and solid detergent source were typically placed in separate containers and mounted on a nearby wall or walls.
- the installation of a dishwashing machine of the prior art required a substantial amount of labor.
- the machine, once installed, took up a substantial amount of space in the commercial establishment in which it was used.
- Inversion type detergent dispensing apparatuses which invert an open upright container of detergent to an inverted position over a nozzle which sprays water into the detergent container in order to produce a detergent solution are known.
- Known inversion type detergent dispensing apparatuses of the prior art such as those disclosed in U.S. Patent No. 4,020,865 and U.S. Design Patent No. 244,598, both assigned to Applicant, relate to powder detergent dispensers useful in converting powder detergent from 5 to 10 cylindrical gallon containers into concentrated detergent solution.
- the detergent dispenser disclosed in U.S. Patent No. 4,020,865 is not designed to function only with a particularly designed container as is the present invention, in which only containers having a particular shape including an indentation will cause the flip-top detergent dispenser of the present invention to properly function and water to spray onto the detergent product.
- the present invention addresses these problems by providing for a self-contained dishwashing apparatus in which both the solid detergent source and solid rinse aid are mounted directly on top of the machine. This saves both labor for the installers of the dishwashing apparatus and saves space for the commercial establishment in which the dishwashing apparatus is installed.
- the present invention also provides for the use of only one outside waterline instead of the more typical three.
- a main pump which is responsible for circulating water through rotating nozzle arrays contained within the machine also serves to direct pressurized water to a solid detergent source and a solid rinse aid source.
- the use of a pump to feed water to the solid additive sources eliminates the need for the two extra waterlines of the prior art and also the pressure regulators, pressure gauges and vacuum breakers which were included on each waterline in order to maintain a constant pressure. This results in a substantial cost savings.
- the dishwasher apparatus of the present invention also saves on the cost of hot water and additives. After a complete cycle of the dishwasher apparatus of the present invention has been run, the final rinse water which contains both a rinse aid and a sanitizer is retained within the sump of the machine. The user of the dishwasher apparatus can remove the clean dishware from the machine and insert soiled dishware for the start of the second complete cycle.
- the initial fill cycle which started the first complete dishwasher cycle by running two gallons of clean, hot water into the machine can be skipped at the beginning of this second complete cycle.
- the second complete cycle instead begins by recirculating the previously used rinse water left over from the first complete cycle through the rotating nozzle arrays and against the solid detergent source. This results in a savings not only of hot water, but also of rinse aid and sanitizer.
- the use of the dishwasher apparatus of the present invention also results in a savings of detergent.
- the solid detergent dispenser mounted on top of the dishwashing machine of the present invention comprises a funnel-shaped metallic holder which serves to hold an inverted container of solid detergent having an opening in such a position as to allow water to spray through a nozzle located in the funnel-shaped metallic holder against the solid detergent in order to produce a detergent solution.
- Encircling the upper interior edge of the funnel-shaped metallic holder is a circular metallic ring having a plurality of holes.
- a waterline connected to the ring serves to flush water out through the plurality of holes down into the interior of the funnel-shaped metallic holder into a line leading to the sump of the machine.
- This flushing action occurs at certain designated times in the dishwasher cycle in order to ensure that any detergent that has conglomerated in the funnel-shaped metallic holder is flushed down the interior of the funnel-shaped metallic holder and transported to the sump. This process helps insure that no wasting of detergent occurs.
- the present invention's use of only one outside waterline instead of the more typical three of the prior art results in a savings of additives such as detergent.
- the additives are fed by a pump with water contained in the sump of the machine rather than outside waterlines.
- the problem of losing clean, hot water and additives down through the overflow valve which occurred in machines of the prior art is solved since no additional water is added to the machine to form additive solutions.
- additive solutions are formed only by using water which enters the machine during a fill cycle.
- no wasting of clean, hot water or additives occurs with the use of the present invention.
- the dishwashing apparatus of the present invention is designed so that water containing detergent solution will not flow back into the incoming waterline.
- the present invention also relates to a flip-top detergent dispenser comprising a base means having a funnel-shaped interior, a nozzle positioned within the interior of the base means, and a detergent container support means connected by a hinge means to said base means.
- the detergent container support means is designed to hold only a particular shaped detergent container, thus helping to insure that only suitable detergent products are used in the warewashing apparatus.
- the flip-top detergent dispenser, mounted on top of the dishwashing apparatus is designed so that the detergent container can be inserted into and removed from the detergent holder support means only in an upright position to prevent dripping of detergent solution onto the user.
- the dispenser of the present invention has a safety feature which prevents water from spraying through the nozzle when no detergent container is present which could cause burns to the user.
- This safety feature of the present invention is more convenient than safety features of known detergent dispensers.
- the funnel-shaped metallic holder of the flip-top detergent dispenser is in close proximity to a cam upon which a weight must press with sufficient force before water will be pumped through the solid detergent source product nozzle.
- This safety feature helps to ensure that hot water is not sprayed out through the funnel-shaped metallic holder unless a particular shaped solid detergent source container is present into which the water will spray.
- This safety feature helps to prevent burns since water will not spray out through the solid detergent source product nozzle unless the particular shaped solid detergent source container is present to push down the cam. If the user inadvertently forgets to insert the solid detergent source container, then no water will flow through the solid detergent source product nozzle during the cycle, which otherwise could result in burns to the user or other nearby persons.
- the detergent container support means of the flip top detergent dispenser can comprise a wire cage assembly.
- the water is shut off, thus assuring safety but without having the user manipulate any lever before tilting the wire cage assembly of the flip-top detergent dispenser.
- the present invention is thus more convenient to use than known detergent dispensers while at the same time preserving a high level of safety by ensuring that water will not spray out of the product nozzle when no detergent container is present.
- the wire cage assembly of the flip-top detergent dispenser of the present invention permits the user to see the container while it is in the dispenser, thus allowing the user to see and read any warning labels and instructions printed on the container.
- the wire cage assembly can be pulled downward by the use of a handle located on the top portion of the wire cage assembly from an initial closed upsidedown position to an open upright position.
- the solid detergent source container can be slipped into the wire cage assembly in its open position such that the solid detergent container is in an upright position with the open mouth of the container facing up.
- the user of the flip-top detergent dispenser can then push the wire cage assembly back into its initial closed upsidedown position in contact with the funnel-shaped metallic holder by use of the handle located on the wire cage assembly.
- the solid detergent source container is now resting in an inverted position with the bottom of the solid detergent source container up in the air and the open mouth of the solid detergent source container positioned over the product nozzle positioned in the interior of the funnel- shaped metallic holder.
- the user To remove the solid detergent source container, the user simply pulls down on the handle connected to the wire cage assembly so that the wire cage assembly is in an open upright position and thus, the solid detergent source container which was in an inverted position previously is now right side up. The user can now look down into the solid detergent source container and see the amount of detergent left.
- a user would remove the inverted detergent source container by lifting it straight up out of its holder and often times look straight up into the container itself to see how much detergent was left. This was a dangerous practice since drops of detergent solution could flow out of the container resulting in injury to the user's eye.
- the present invention solves this problem in that the solid detergent source container is removed in an upright position wherein the user can easily look down into the solid detergent source container to see how much detergent is left and therefore must wait until the solid detergent source container is in an upright position before looking into it. This is in contrast to the prior art dispensers in which a user did not have to invert the solid detergent source container into an upright position before looking into it to see how much detergent was present.
- the flip-top detergent dispenser of the present invention has numerous safety features.
- Automatic safety features include a cam situated next to the base means which will not be activated unless a particularly shaped detergent container is situated in the detergent support holder and the detergent support holder is closed. Only when the cam is activated can water spray up through the product nozzle.
- spacers in the hinge means of the flip top detergent dispenser help prevent a user from catching or cutting his fingers when opening or closing the flip-top detergent dispenser.
- the detergent support holder has open areas so that labels including instructions and warnings can be read on the solid detergent container.
- a circular metallic ring having a plurality of holes is situated around the funnel-shaped interior of the base of the flip-top detergent dispenser. Water is flushed through the holes of the circular metallic ring at designated times in the warewashing cycle serving to insure that the detergent is rinsed down through the funnel-shaped interior of the base and that it does not conglomerate there resulting in a savings of solid detergent source.
- the warewashing apparatus of the present invention has a typical complete cycle of ninety seconds.
- the complete cycle comprises a number of shorter individual cycles.
- the length of the shorter individual cycles comprising the complete cycle and thus the length of the complete cycle itself can be shortened or lengthened.
- the first individual cycle is the first fill cycle which lasts approximately 14 seconds.
- the second cycle is the wash cycle which lasts approximately 44 seconds. There is a 5.4 second overlap of the end of the first fill cycle and the beginning of the wash cycle.
- Main pump 15 is activated throughout the wash cycle. Main pump 15 directs water to rotating nozzle arrays 20a and 20b and to other areas of machine 1 when appropriate valves are opened.
- the wash cycle includes the following steps.
- the final cycle is the rinse cycle which last approximately 21 seconds.
- chlorine sanitizer is added to sump 9 of machine 1 along with a rinse aid solution which is formed during the rinse cycle.
- water is directed to rotating nozzle arrays 20a and 20b. At the end of the rinse cycle, the water containing sanitizer and rinse aid is retained within sump 9 of machine 1.
- Line 7 could be attached to other portions of machine 1 in order to deliver water to sump 9. However, by adding the water at the top of machine 1, it serves to contact the soiled dishware with water, thus serving a rinsing function.
- Solenoid actuated on/off valve 5 is operated by means of a cam 72 (not shown) in control cabinet 10 situated on top of machine 1.
- Cam 72 causes solenoid actuated on/off valve 5 to open for approximately 2 - 4 seconds allowing enough water through vacuum breaker 6 and line 7 to fill sump 9 with approximately two gallons of water.
- Electrical line 80 extends from solenoid actuated on/off valve 5 to control cabinet 10.
- Overflow valve 11 serves to prevent overfilling of sump 9. Excess water is drained through overflow valve 11 into line 12 which leads from the bottom of sump 9 into metal box 13 which is located beneath machine 1. Metal box 13 contains a perforated horizontal filter 14 which serves to collect food and other debris. Horizontal filter 14 can be manually removed and cleaned. Water draining through overflow valve 11 flows into metal box 13 through horizontal filter 14 and through a line (not shown) leading into the city sewer system.
- main pump 15 is activated by cam 73 (not shown) in control cabinet 10.
- the water which has collected in sump 9 is drawn by means of main pump 15 through coarse in-line filter 16 which is located beneath sump 9.
- Coarse in-line filter 16 comprises a perforated metal cylindrical filter enclosed in a cylindrical metal casing. The upper edge of the perforated metal cylindrical filter is sealed to the cylindrical metal casing.
- a drain valve (not shown) is attached to the bottom of coarse in-line filter 16. Coarse in-line filter 16 is positioned over metal box 13. The drain valve is not opened until later in the cycle.
- the drain valve is opened by means of cam 74 (not shown) in control cabinet 10, all water in machine 1 including the water within sump 9 drains down through coarse in-line filter 16 and fine in-line filter 17, along with any debris that has collected in coarse in-line filter 16 or elsewhere in machine 1, into metal box 13 through horizontal filter 14, into a line (not shown) which leads to the city sewer system.
- Horizontal filter 14, located in metal box 13 serves to collect food and other debris.
- Main pump 15 thus draws the water which has started to collect in sump 9 through line 18, through coarse in-line filter 16, and directs the water through line 19 to rotating nozzle arrays 20a and 20b.
- Rotating nozzle array 20a attached to the upper interior surface of machine 1, serves to deposit water down onto the soiled dishware contained in rack 4.
- Rotating nozzle array 20b situated in sump 9 of machine 1, serves to spray water up against soiled dishware contained in rack 4.
- solenoid valve 21a contained in box 21 is opened by means of cam 75 (not shown) in control cabinet 10 at the same time main pump 15 is activated.
- the opening of solenoid valve 21a serves two functions. The first function is to allow air to be purged from fine in-line filter 17 situated above machine 1.
- Fine in-line filter 17 comprises a 40 mesh polyethylene cylindrical screen 17a encased within a cylindrical TPX plastic housing 17b.
- Fine in-line filter 17 can be purchased from RON-VIC Company.
- Fine in-line filter 17 serves to trap food particles which can clog up solenoid valves 21a, 21b, and 21c contained in box 21, product nozzle 22 directed towards a solid detergent source in solid detergent source container 23 and the product nozzle directed toward rinse aid 24 in rinse aid container 25.
- the second function of solenoid valve 21a is to allow water to be pumped through line 27 to flip-top detergent dispenser 30.
- Flip-top detergent dispenser 30 comprises a nozzle shaped metallic holder 31 connected to wire cage assembly 32 by hinge means 33.

- This flushing of water through the holes in circular metallic ring 37 serves to rinse out any detergent material which has collected in the interior of the funnel-shaped metallic holder 31 during a previous detergent solution formation cycle.
- Solenoid valve 21a is initially activated to purge fine in-line filter 17 of air and direct water through perforated circular metallic ring 37 in a preflush step to remove any detergent material left from a previous detergent solution formation cycle around the interior of the funnel-shaped metallic holder 31.
- solenoid valve 21a Immediately after solenoid valve 21a is opened and fine in-line filter 17 is filled with water and purged of air solenoid valve 21a is closed and solenoid valve 21b is activated by cam 76 (not shown) in control cabinet 10 allowing water to flow through line 28 where it is sprayed through product nozzle 22 onto the solid detergent source (not shown).
- Solenoid valve 21b is then deactivated after 2 seconds have elapsed. Solenoid valve 21a is then reactivated for 5 seconds in a final flush step.
- the detergent solution After the detergent solution reaches sump 9, it is pumped out along with any water contained in sump 9 by means of main pump 15 through coarse in-line filter 16 through line 19 to upper and lower rotating nozzle arrays 20a and 20b where it is sprayed onto dishware located in rack 4 and collects in sump 9 to be recirculated.
- a solenoid valve contained in box 38 connected to the side of coarse in-line filter 16 is activated by cam 74 (not shown) in control cabinet 10 causing water and debris to drain from machine 1 into metal box 13 through horizontal filter 14 into a line (not shown) directed to the city sewer system.
- Debris contained in coarse in-line filter 16, fine in-line filter 17, and elsewhere in machine 1 exits through a drain valve (not shown) connected to the bottom of coarse in-line filter 17 through metal box 13 located under machine 1 where it is trapped by horizontal screen 14.
- Horizontal screen 14 can be manually removed and cleaned to remove debris which has collected.
- main pump 15 is activated by cam 73 (not shown) in control cabinet 10.
- Main pump 15 draws water through coarse in-line filter 16 and directs it through line 19 to rotating nozzle arrays 20a and 20b.
- Solenoid valve 21c is then opened for approximately 6 - 8 seconds by means of cam 77 (not shown) in control cabinet 10 allowing pressurized water to flow through fine in-line filter 17 at points 17c and 17d, and out through line 26.
- the water is then pumped through line 29 and is sprayed by a product nozzle onto rinse aid 24 contained within rinse aid container 25 which is situated on top of machine 1.
- a rinse aid solution is formed by the contact of water sprayed through the product nozzle onto rinse aid 24.
- the rinse aid solution thus formed flows through line 39 into sump 9.
- rinse aid container 25 comprises a clear cylinder 40 having a flip-top lid 41, through which the solid rinse aid 24 itself is inserted into rinse aid container 25.
- the clear cylinder 40 allows the user of the dishwasher apparatus to determine by visual inspection the amount of rinse aid 24 present in rinse aid container 25.
- the base of rinse aid container 25 comprises a cylindrical metal base 42 having a series of four circular screens situated in the top interior portion thereof.

- Wire cage assembly 32 has two projection means 60a and 60b extending inward into the circular space defined by second circular metallic wire 59. Projection means 60a and 60b correspond in shape to curved vertical indention 55 of solid detergent source container 23. Wire cage assembly 32 has an opening at point 34 defined by second circular metallic wire 59 and ends 57a and 57b of first circular metallic wires 57. When the flip-top detergent dispenser 30 is closed, and no solid detergent source container 23 is present, the open space 58 in wire cage assembly 32 is positioned over cam 66 in such a manner that it does not contact cam 66. Thus, flip-top detergent dispenser 30 by itself when closed does not function to contact cam 66.
- First circular metallic wire 57 is designed with a smaller circumference than second circular metallic wire 59.
- solid detergent source container 23 can slide past second circular metallic wire 59 but is stopped by first circular metallic wire 57 at second rim 56 of solid detergent source container 23, said first circular metallic wire 57 having a smaller circumference than the circumference of second rim 56 and cylindrical portion 50 of solid detergent source container 23.
- the first circular metallic wire 57 serves to catch solid detergent source container 23 as the wire cage assembly 32 is lifted and pushed forward so that solid detergent source container 23 does not come flying out through wire cage assembly 32 as wire cage assembly 32 is closed.
- the wire cage assembly 32 is also advantageous in that it allows the user to look through the wire cage assembly 32 at the solid detergent source container 23 to identify the product by means of product labels and to read any directions or warnings printed thereon.
- solid detergent source container 23 is clear or transparent so that the user can determine the amount of solid detergent source left by looking through the clear or transparent container 23 while container 23 is situated in place on machine 1.
- the user To remove solid detergent source container 23 from wire cage assembly 32, the user first pulls down on handle 64 on wire cage assembly 32 so that wire cage assembly 32 is in an open position. To remove solid detergent source container 23 from now opened wire cage assembly 32, the user merely grasps handle 71 attached to base 69 of solid detergent source container 23 and lifts the solid detergent source container 23 very slightly, tilting the bottom of solid detergent source container 23 towards the user and the top of solid detergent source container 23 away from the user and thus pulling solid detergent source container 23 out of wire cage assembly 32.
- the user To insert solid detergent source container 23 into wire cage assembly 32, the user merely lines up the vertical indentation 55 on solid detergent source container 23 with projection means 60a and 60b on wire cage assembly 32 and holding onto handle 71 of solid detergent source container 23 slides solid detergent source container 23 into wire cage assembly 32 by tilting the top of solid detergent source container 23 away from the user and sliding solid detergent source container 23 up into wire cage assembly 32, with projection means 60a and 60b moving within indentation 55, with base 69 of solid detergent source container 23 sliding back down to rest on the semi-circular portion of wire 62 of wire cage assembly 32.
- flip-top detergent dispenser 30 When flip-top detergent dispenser 30 is in an open position, the user can slide the upright solid detergent source container 23 out of wire cage assembly 32 according to the previously described method and then look down into the opening of the removed solid detergent source container 23.
- the solid detergent source container 23 is in an upright position after removal. Thus, a user can immediately look down into the solid detergent source container to determine the amount of solid detergent source left.
- the flip-top mechanism detergent dispenser aids the user in that it inverts the solid detergent source container before the user has an opportunity to look into the container.
