The present invention relates to a post-mix soft drink dispenser, a gravitational drop syrup container supply system, and a syrup supply system and associated carbonic acid refrigeration apparatus.

As an example, a conventional postmixed soft drink dispenser device is inverted with a number of disposable plastic flavor concentrate containers of about 1.5 liters in size so that the necks of the containers fit into the sockets in the dispenser nozzle assemblies. It is possible to selectively extract the post-mixed carbonated soft drink. These 1.5 liter containers are securely supported by the neck of their container fitted in a socket. These containers are unitarily cooled by a single heat transfer bracket in contact with the containers. The heat transfer brackets are cooled by the freezing device in the refrigeration system.

The dispenser support structure and the refrigeration system of the type described above are well suited for a 1.5-lead container. The gist of the present invention, however, is to provide an improved support structure and refrigeration system that may be suitable even when a spice concentrate container with a capacity of about 4 liters is used.

In addition, there has conventionally been a need for a cabinet assembly for a post-mix soft drink dispenser having a cabinet part number that can be fixed together by a minimum fastener. Of course, this is advantageous not only in terms of lower manufacturing costs of the distributor cabinet, but also in that the assembly can be completed quickly and uniformly. It can also be assembled with a minimum number of parts, making maintenance and repair simple.

The present invention also relates to a post-mixed soft drink dispenser, a gravimetric drop syrup container supply system for this, and a syrup supply system which can be easily detached and adapted for maintenance and repair and an improved refrigeration system for a carbonated carbon dioxide.

Maintenance and repair of the refrigeration system of the soft drink dispenser will be simple if the main parts of the refrigeration system can be withdrawn ten times from the external cabinet assembly and then easily reinserted into the cabinet after maintenance and repair has been completed. Previous soft drink dispenser cabinets and refrigeration section designs were designed to be separated into the majority of discrete components rather than being modularized and withdrawn, so there was no satisfactory solution to this problem.

The present invention also relates to a post-mixed soft drink dispenser, a gravity drop syrup container supply system for it, a syrup supply system and associated carbonic acid refrigeration system for both carbonation and an improved stirrer assembly for a refrigeration system.

Stirrer assemblies for circulating water in a cooled bath of a postmixed soft drink dispenser are generally known. During heavy use of these distributors, there is a possibility that the electric motors that drive the impellers of the agitators generate heat and heat can reach the damage level, resulting in damage to the motor. There is therefore a need for means for dissipating heat to prevent damage to the stirrer motor.

It is therefore an object of the present invention to provide an improved refrigeration system for a flavor concentrate container of a gravity drop type post-mixed soft drink dispenser.

It is a further object of the present invention to provide an improved support structure for a flavor concentrate container capable of supporting axial as well as longitudinal direction in a gravity drop type post-mixed soft drink dispenser.

It is a further object of the present invention to provide a cabinet assembly for a postmixed soft beverage dispenser which can be formed into a minimum of parts that can be fitted together in a modular fashion.

Another object of the present invention is to provide an improved refrigeration system for a soft drink dispenser including a unit which is detachable for easy maintenance and repair as a unit having many parts.

Another object of the present invention is to provide a heat dissipation means of the electric motor of the refrigeration system stirrer assembly.

Another object of the present invention is to provide a single support structure for the stirrer assembly.

It is another object of the present invention to provide a support structure for an agitator assembly in which other refrigeration control components such as ice detection probes can also be supported.

Advantages associated with the object of the present invention can be clearly understood from the following description described with reference to the accompanying drawings.

Referring to FIG. 1, there is shown a soft drink dispenser generally comprising an upper cabinet portion 12 and a lower pedestal portion 14, indicated by reference numeral 10. FIG. The pedestal 14 contains system controllers, electrical wiring, liquid hoses and mechanical components of the refrigeration system of the present invention.

The upper cabinet part 12 contains a water tank containing a number of syrup or flavor concentrate containers in a syrup containment compartment behind a removable panel 18 and a carbonated tank under the removable panel 21. A detailed description thereof will be described later with reference to FIGS. 2 and 3.

The post-mixed soft drink dispenser 10 shown in FIG. 1 selects and presses the desired pushbutton of the three pushbuttons 22 and in response to the operation, the selected soft drink of the three flavors is dropped through one of the selected nozzles 20 16. It is discharged into a container placed on the bed. As in the prior art, the flavor concentrate or syrup is mixed with the carbonated water in the nozzle 20 to prepare a post-mixed soft drink.

2, the after-mixed soft drink dispenser 10 is shown with the front cover 18 removed, showing the syrup feed compartment SC of the syrup or flavor concentrate supply system of the present invention. Flavor concentrates, such as syrup, are contained in three inverted syrup containers 24, which can be seen in FIG. The cylindrical vessels 24 shown in FIG. 4 may also be of the type described in U.S. Patent Nos. 504,865 and 504,866, filed on June 6, 1983, assigned to the assignee of the present invention.

These vessels have a flow rate control tube punched through the bottom of vessel 24 (top of the vessel shown in FIG. 2) while having a diaphragm that can rupture on the spout of the vessel in the neck 24D. The neck 24D is at the bottom of the container shown in FIG. The rupturable diaphragm is drilled by a perforation device placed in the center of each socket 34 (FIG. 3), connected to the nozzle 20 by a suitable valve device (not shown), and the valve can be operated by pushing by the push lever 22. have. Valve devices and fabric mills may be those described in US Pat. No. 4,306,667 to Sedam et al. Assigned to the assignee of the present invention.

The syrup container 24 of FIG. 4 is inserted into the postmixed soft drink dispenser 10 by turning them over and inserting their neck 24D into each of the barrel nozzle 20 and the associated socket 34 of the tube. The container 24 of FIG. 4 is hermetically sealed and must be removed before the neck is inserted into the socket.

In order to firmly support the syrup containers 24, the cooling vanes 28 associated with each container are of reduced diameter cross-section 24B of the container 24, placed adjacent to the rib 24A, in the form of a circular circular curve. As shown in Figure 3, the cooling vanes 28 are generally semicircular in cross section but cut into circular arches over 180 degrees so that their ends are bent outwardly to receive the outer surface 24B of the containers 24. good. Thus, the containers 24 can be inserted into and tightly inserted into the U-shaped passages formed by the cooling vanes 28 so that they are in good thermal contact with them, while the wings 28 can firmly support the containers 24 in their respective sockets 34.

Another support of vessel 24 is a support S that is upright on both sides of the socket 34. As shown in FIG. 2, these supports S have an inclined surface which is in contact with the inclination angle of the surface 24C on the container 24. As shown in FIG.

As shown in FIG. 2, the cooling blade 28 is detachably connected to the cooling plate 26 by a pair of fixing holes 32 extending from the cooling plate 26 and fitted to the head of the fin 30. As shown in FIG. The cooling vanes 28 are thus connected to the cooling plate 26 by means of combining good heat transfer between them, which can be easily pulled out for cleaning or replaced for repair. The cooling blade 28 has a split portion 28A formed at the center so that the head of the pins 30 can be inserted therein. This ensures that the head of the pins 30 and the container are free of obstacles between the surface 24B of the 24.

3, the heat transfer interrelation between the cooling vane 28 and the refrigeration system of the present invention is shown. 3 is a top plan view of the postmixed soft drink dispenser of FIG. 1 with both front cover 18 and top cover 2l removed to show the arrangement of the components in the syrup containment SC and the water tank WR of the present invention. The water is connected to the water tank WR through the water pipe WL and the water pipe WL is connected to a water supply source such as a city water supply. The water tank WR is large enough to occupy the entire rear wall of the containment chamber SC containing the syrup container 24. Inherent in direct contact with the front wall 36 of the bath WR (shown in cross section) is the cold plate 26 made of stainless steel or other suitable thermal conductor. Therefore, the cooling temperature of the water in the bath WR is transmitted to the cold plate 26 in the syrup containment chamber SC through its front wall 36. This cooling temperature is then transferred to the cooling vanes 28 and the containers 24 snapped into it. Cooling vanes 28 may be made of stainless steel, aluminum or other suitable material. The water in the bath WR is cooled by the evaporator coil EC, which is part of a conventional refrigeration system comprising a compressor and a condenser arranged in the pedestal 14 of the distributor 10. The evaporator coil EC in the bath WR thus cools the water to the desired temperature selected by a suitable controller in the refrigeration system arranged in the pedestal 14.

A carbonation tank CT is also arranged in the bath to further benefit the water cooling effect in the bath WR. The carbonation tank CT is inverted so that all coupling devices from nozzle 20, such as CO ₂ input line, water input line and carbonated water output line, are connected to the appropriate conduits or valves in pedestal 14 through the bottom of the water tank WR.

The bath WR also has outlet D and a suitable electric level controller to prevent water from overflowing and to control its volume. The bath WR is inexpensive and light because it is injected into plastic. The same is true for the base plate in the syrup containment chamber SC in which the sockets 34 are arranged. The support S may be molded integrally with the support plate.

Agitator A is installed in the water tank WR to circulate water, creating a continuous flow of water across the front wall 36 of the water tank WR. This helps to keep the temperature of the cold plate 26 and the cooling vanes 28 constant. Agitator A and a suitable drive motor therefor may be supported at the bottom of the front cover 18. Therefore, by covering the cover, the stirrer is inherent in the water bath WR.

To prepare for operation of the postmixed soft drink dispenser 10, a syrup container with a suitable flavor concentrate is placed in the syrup containment chamber SC by inserting 24 necks 24D into sockets 34. Once the containers 24 have been inserted into the sockets they are also snapped into the cooling vanes 28 and fitted tightly. When fully inserted into the socket 34, the burstable diaphragms above the vessel openings can be drilled out of gravity into the associated valve device. The valve device is also connected to the carbonated water output line of the carbonation tank CT. Therefore, when operating the selected one of the push operations 22, the syrup and the carbonated water can be mixed in the relevant nozzle 20 to prepare a post-mixed soft drink of the desired flavor.

The syrup remains cool because of the heat transfer couplings between the front wall 36, the cold plate 26, the cooling vanes 28 and the vessels 24 of the bath WR. The carbonation tank CT is also cooled by water in the bath WR. Therefore, cold after-cold soft drinks can be obtained as ordered.

Snap fits between vessel 24 and cooling vanes 28 not only provide good thermal bonding over loose fit but also increase cooling efficiency. The cooling vanes 28 also help to hold the containers 24 as well as to prevent piercing.

The refrigeration system of the present invention is particularly effective for cooling the syrup containers 24 either conductively or convectively. Cooling vanes 28 are conductive cooling bodies and cooling plate 26 is a convective cooling body in which air flows from its wide surface to the syrup container.

Another embodiment of a refrigeration system suitable for use with the dispenser of the present invention is shown in FIGS. In this embodiment, the water in the bath WR is non-drinking water rather than drinking water as in the first embodiment. That is, the water tank WR is filled with water used only as a refrigerant in the carbonation tank CT and the cooling plate 26. In this embodiment the drinking water to be carbonated is introduced through a water coil 42 disposed around the bath WR. Details of the water coil 42 will be described later in FIG. One end of the water coil 42 is connected to a high pressure pump WP which may be connected to a water supply or other suitable source. The output of coil 42 is connected to input coupling 40 on top of the carbonation tank CT. Thus, the drinking water entering its carbonation tank 40 through its top increases the ability to quickly absorb the CO ₂ gas synthesized at high pressure when it enters the carbonation tank CT. As shown in FIG. 8, the entire water coil assembly 42 can be easily removed from the bath WR for repair.

In this embodiment of the refrigeration system of FIGS. 5-9 the evaporator coil comprises exposed coils of copper pipe EC ₂ because the water it is submerged is non-drinking water. This is different from the embodiment of FIG. 3 in which the evaporator coil enters the housing and is separated from the drinking water in the bath. Its cooling efficiency for water in the bath WR is improved by removing the housing of the evaporator coil circumference.

As shown in FIG. 5, the pair of ice detection tower needles P ₁ and P ₂ are used to detect freezing near water coil 42 and stirrer impeller A, respectively. These ice detection probes are connected to a suitable control circuit to turn off the refrigeration compressor when ice freezes near water coil 42 or agitator impeller A. As described below with reference to the stirrer and ice probe assembly of FIG. 9, the probes P ₁ and P ₂ are mounted on the stirrer and ice probe assembly in a predetermined space, so that the stirrer assembly of the water bath WR as shown in FIG. When placed on top, the probes P ₁ and P ₂ are placed at the appropriate positions adjacent to the water coil 42 and the evaporator coil EC ₂ , respectively.

The method of assembling the cabinet structure and parts thereof of the present invention is described in detail in FIGS. FIG. 6 is an exploded view of the entire cabinet assembly, FIG. 7 is an exploded view of the upper housing assembly and FIG. 8 is how the upper housing assembly is attached to the lower housing assembly and how the water coil 42 and the evaporator coil EC ₂ are inserted into the distributor cabinet. Is a developed view. In these figures, the same parts as those described above in FIGS. 1 to 4 are denoted by the same reference numerals.

A detailed view of FIG. 7 shows its development showing how the upper housing assembly of the present invention, indicated by reference numeral 12, is assembled. The upper housing assembly has a main frame with a rear compartment 12R and a front compartment 12F which deflects the syrup compartment SC. These two compartments are interconnected by a common wall through an opening or window 12W in which the cold plate 26 is arranged. The cooling plate 26 is attached to the front wall of the water tank WR by the heat conductive resin TM. Gasket 41 fits within window 12W.

The cold plate 26 to which the bath WR is attached thereto by means of resin TM is then inserted into the rear compartment 12R of the upper housing assembly and secured in place by screws or the like. The tank WR is slightly smaller than the rear enclosure 12, which forms the space between the side and the rear. This space is filled with insulation such as polystyrene foam. The cooling vanes 28 are then attached to the screws 31 installed on the cooling plate 26 (see figure 8) by wing nuts 29. Then the assembly of the upper housing part is completed except for the water coil 42 and the evaporator coil EC ₂ .

This upper housing assembly 12 is then attached to the lower housing assembly 14 in the manner shown in the development of FIG. As shown in FIG. 9, the lower portions of the side walls of the main frame of the upper housing assembly 12 have grooves 12A and 12B therein. These steals are designed to fit tracks on the vertical side walls of the lower housing assembly l4 to 14A and 14B. However, before sliding the frame of the upper housing assembly 12 with the grooves 12A and 12B onto the tracks 14A and 14B, the syrup compartment backing plate 35 is aligned with the socket holes in the lower housing assembly 14.

The upper housing assembly 12 is then fitted on the tracks 14A and 14B so that the syrup containment base plate 35 locks in place in the distributor housing assembly. The threaded sockets 12C, 12D engage with threaded holes (not shown) on the bottom of the valve assembly housing to provide a stable connection between the upper and lower housing assemblies. This configuration and assembly method using the grooves 12A, 12B and the tracks 14A and 14B allows the upper housing assembly 12, the lower housing assembly 14 and the syrup containment backing plate 35 together to pass through the holes in a pair of socketed sockets. It can be combined with Nasan alone.

Referring to FIG. 8, it can be seen that the water coil assembly 42 can be easily inserted into the water bath WR through its upper hole. The water inlet 42A of the water coil is installed in the water pipe section extending over the rear wall of the water tank WR through a hole WS below the appropriate location in the lower housing assembly to connect to a high pressure pump that can be coupled to a water source. The discharge end of the water coil 42B is connected to the coupling part 40 of the upper part of the carbonation tank CT as described above with reference to FIG. The coil assembly 42 also has three support brackets 42C, 42D and 42E on the top edge of the bath WR to support the coil assembly 42 inward near the peripheral sidewalls. The length and diameter of the coil 42 is chosen according to the distributor conditions that determine the degree of cooling required by the coil 42.

Another unique feature of the invention is that the mechanical refrigeration system of the dispenser of the invention is in such a way that it can be easily inserted and removed from the cabinet assembly. As shown in FIG. 8, the mechanical refrigeration assembly is mounted on a compressor deck CD, which includes a compressor C, a condenser CN, a transformer TR, an electric fan motor FM and a deck blade F. Extending up from the compressor deck is the flexible part of the evaporator coil T, which supports the evaporator copper coil assembly EC ₂ with the aid of a removable support rack (not shown). The compressor deck CD slides in to place in the enclosure 14H in the lower cabinet assembly to insert the compressor deck assembly CD and its evaporator EC ₂ into the appropriate positions in the lower cabinet assembly 14 and the bath WR, respectively. When it is located, the evaporator coil brace EC ₂ can still be vertically supported by a removable support rack and compartment T in a vertical position extending upwards at the upper edge of the water bath WR as shown in FIG.

The coil assembly EC ₂ is then coiled and bent downwards to reach a suitable position in the water bath WR shown in FIG. Section T can be bent several times without fatigue or damage, so copper is preferred. The flexible tube part T is located in a hole in the upper edge of the bath WR. If the evaporator EC ₂ needs to be repaired, the above disassembly steps are reversed. That is, the coil EC ₂ is bent above the water bath WR and the compressor deck CD slides in from behind the lower cabinet assembly 14. Thus, the mechanical refrigeration system of the beverage dispenser of the present invention can be easily pulled out or inserted into the dispenser cabinet assembly to make it compact and modular and easy to manufacture, maintain and repair.

The compressor deck CD associated with the evaporator coil assembly EC ₂ can be put in place and then the stirrer and probe assembly of FIG. 9 can be inserted into the water bath WR. The location of this stirrer and probe assembly A ₁ is shown in FIG. This assembly A ₁ has two pairs of arms as described below to be inserted and supported in the holes AS in the upper edges of the wall of the water tank WR. Rapid disassembly couplings are also fitted to the power supply. Thus, the stirrer and probe assembly can also be easily inserted and removed from the cabinet for easy maintenance and repair.

The development of FIG. 6 shows how all the parts of the cabinet of the invention described above with reference to FIGS. 7 and 8 are assembled together in a single cabinet structure to form the soft drink dispenser shown in FIG. What can be seen from FIG. 6 is that the cabinet assembly and the parts of the mechanical refrigeration system shown in FIGS. 7 and 8 have been assembled together, all other necessary hardware has been inserted, the front plate 44 attached to the lower housing assembly and the upper and lower housing assemblies The entire cabinet assembly is completed by attaching the rear panel 46 to the rear of the 12 and 14. The removable covers 18 and 21 are then fixed to cover the syrup compartment SC and the bath WR respectively. Although not particularly visible, the removable cover 18 on the syrup containment SC has a pair of protrusions that must fit within the holes 17 of the pair of taps on the back of the syrup containment SC as shown in FIG. Lean.

6 also shows a detail of a typical syrup socket 34, which includes a syrup seal member 34C, a syrup liner seal member 34B and a seal member retainer 34A. These elements fit snugly within the openings 35A of the syrup support plate 35 to interact with the syrup container with the neck portions 24D of 24 in the manner described above. In this embodiment of the present invention, the syrup support plate 35 has a vertical front rib member S2, unlike the plurality of supports S shown in the embodiment of FIG. This rib member S2 supports the containers 24 to the support S in a vertical stable state in the same manner. The stirrer and probe assembly of the present invention is shown in detail in the development of FIG. 9 and is generally represented by A ₁ . This assembly includes a main housing 50 having two pairs of support arms 50A which fit the grooves or holes in the top of the water tank WR shown in FIG. The main housing also has ice detection probes P ₁ and PS ₂ . Installed in the central containment of the housing 50 is the stirrer motor AM coupled to the impeller A through the impeller shaft 54, which is submerged in the water in its final working position, the water tank WR. Also, which will downwardly from the housing 50 is a heat sink HS to have a pair of arms HS ₁ and HS _2. The heat sink HS discharges the heat generated by the stirrer motor AM into the non-potable water in the bath WR. The cover 52 is also fitted over the top of the stirrer motor so that it is fixed in the housing 50. As described above, this stirrer and probe assembly is placed on top of the water tank WR, impeller A, probes P ₁ , P ₂ and heat sink arms HS ₁ , HS ₂ are submerged in water in the water tank WR, and the arms HS ₁ , HS ₂ Is extended to a position in contact with or subsequent to the evaporator coil EC ₂ to maximize heat release. The probes P ₁ and P ₂ are placed on the predetermined space of this assembly so that they are properly positioned in the water coil 42 and in the water bath WR near the stirrer impeller A as shown in FIG.

It will be appreciated that the systems described so far may be modified by those skilled in the art within the spirit and scope of the present invention.
