Description

DETAILED DESCRIPTION OF THE INVENTION For many years, the food and beverage industry has focused on liquid retention and retention of non-carbonated beverages.
Refrigeration and dispensing equipment has been in widespread and common use.

The most commonly used type of beverage mixer has a box-like outer shell suitable for mounting and supporting on a countertop, with a light-colored or transparent beverage reservoir on top. It is a type of device that houses a cooling device, a circulation pump device, and/or components and parts of a mixing valve device. In the case of instruments such as
Closed with a removable lid. The purpose of operation of the circulation pump device is to withdraw the beverage from the bottom of the tank, and it also includes a return pipe and the like. These return pipes allow the beverage to be directed to the top of the vat and then flow down over the entire internal surface of the casserole, providing an aesthetic effect and serving to keep the beverage in a mixed state. Cooling devices commonly included in the apparatus to which this application pertains include a compression and condensation device within the casing and protruding upwardly from the casing into the bath to effectively cool the beverage in the cassette. There is an evaporator coil. Dispensing valve systems commonly include simple on-off valves located within the envelope. The inlet side of the valve is suitably connected to the bottom of the reservoir, and the outlet side is followed by a suitable dispensing pipe. The dispensing tube extends to a destination outside the envelope so that the beverage can be directed into a drinking cup or glass. Finally, there is a manual valve actuation lever that can be operated outside the envelope. The relationship between the discharge end of the outlet pipe and the glass holding reservoir located on the front side of the lower part of the jacket is such that the former is located above the latter and is separated from it. Note that the actuation lever usually includes a bar-shaped component. It is installed at the front of the outer cover and at the bottom of the back of the mixing tube, so if you manually move a glass or other object to the beverage receiving position under the tube, the bar-shaped part will be in the correct position, and then open the valve connected to it. The main drawback of beverage dispensers of the type described above is that the beverage holding capacity in the reservoir requires periodic replenishment.

To replenish the amount of beverage stored in the tank, the lid is usually removed from the tank, and a predetermined amount of water and a predetermined amount of concentrated beverage are poured into a jug, mixing cup, etc. It must be poured into the top of the pot. The work involved is
This is not only unseemly and difficult, but also undesirable and unpleasant in the eyes of the users of the facilities where the machine is used, especially if the person doing it lacks height or arm length, and if there is insufficient cooperation on the part of that person. This is a common task. For this reason, it is common practice for operators of such machines to avoid feeding the liquid reservoir of such machines until absolutely necessary.

The practice of delaying the replenishment of the beverage supply to the reservoir of beverage dispensers of the type described above has an even worse effect.

The effect is that it is impossible for a device to effectively and sufficiently cool or freeze a large quantity of freshly poured unchilled beverage immediately, or at least in a short period of time. be. Therefore, if you allow the amount of beverages in the device to be completely reduced and then replenish it,
Sufficient time must elapse to allow the chiller to cool the beverage, and only then can dispensing of the sufficiently chilled beverage be resumed. Another drawback in the operation and use of the dispenser is that the water and concentrate must be measured by hand, which often results in improper metering. Insufficient or excessive amount of concentrate is used when preparing a new beverage, resulting in a beverage that is too dilute or too strong. Using insufficient amounts of concentrate or selling weak beverages can disappoint customers and potentially result in future business losses for business owners. On the other hand, using too much concentrated beverage or selling a beverage that is too strong generally results in a loss of profit for the operator who owns such equipment. Therefore, the purpose and characteristics of this invention are to "receive water and a concentrated beverage, mix the water and concentrate in a predetermined amount, and immediately dispense the mixed water and concentrate, that is, a newly prepared beverage, into a related beverage mixer. The object of the present invention is to provide a new automatic device for delivering to a tank.

Another object of the invention is a device having the general characteristics referred to above, which is connected to a pressurized water supply system and receives water supply therefrom;
A further object of the present invention is to provide an apparatus that utilizes the water supply as a motive force for drawing and delivering liquid concentrate from a remote concentrate supply source.

Yet another object of the invention is an apparatus having the general characteristics referred to above, in which the amount of concentrate drawn and delivered is proportional to the amount of feed water entering the apparatus, and the concentrate and water are present in said apparatus. The object of the present invention is to provide a device in which a freshly prepared beverage flows out of the device by mixing and mixing.

This is the purpose of the invention.

Other objects and features of the present invention are an apparatus having the general characteristics referred to above, including a liquid level control switch device responsive to the liquid level in the liquid holding tank; An object of the present invention is to provide a device including the on-off valve means for starting/stopping a motor.

Yet another object and feature of the invention is an apparatus having the general characteristics referred to above, including a shunting device between the upstream and downstream ends of the suction means, and further comprising a manually adjustable regulating valve. An object of the present invention is to provide a device that enables adjustment and precise control of the negative pressure generated at the upstream low pressure end of the suction device and the flow rate and flow rate corresponding to the negative pressure of the concentrated liquid sucked and passed through the suction means. . An apparatus having the general characteristics referred to above, which is small, well-proportioned, lightweight and compact, and whose mounting on and support by the beverage dispenser reservoir lid is carried out conveniently and effectively. It is another object and feature of the present invention to provide an apparatus for relieving noise.

Another object and feature of the invention is an apparatus having reference characteristics, in which an elongated vertical beverage delivery tube mounted on a reservoir lid attachment device extends from the device through a hole provided in the reservoir lid. Later, by suspending the liquid below the liquid level in the liquid holding tank, the device is characterized by the fact that there is no scattering of the beverage sent into the pot, or the generation of undesirable air bubbles, noise, etc., and the device has reference characteristics. An object of the present invention is to provide a device characterized in that an elongated goblin included in the opening/closing device is suspended from the mounting device into the cage.

A unitizing device having the reference characteristics as described above, for installation and association with any standard conventional still beverage mixer reservoir;
Simply raise the beverage delivery pipe suspended from the attachment device and a pair of small holes that receive the screw into the liquid storage tank lid, and ensure that the tube and the screw loosely hold or fix the device in a predetermined position with respect to the lid. It is an object and feature of the present invention to provide a unitization device that is made possible simply by creating a featured structure.

FIG. 1 shows a state in which a non-carbonated beverage mixer M is installed on a counter 10.

The dispenser M has a lower jacket 11 which has a front recess 12 for accommodating a container such as a glass and for dispensing the beverage into the glass. A drip pan 13 is provided at the bottom of the recess 12. A beverage blending valve 14 suspends from the top of the cavity into the cavity, and a beverage blending valve actuator 15 is disposed in the cavity between the rear portion of the saucer 13 and the valve 14. A beverage liquid holding tank T is arranged and supported on the upper surface of the outer cover 11.

Since the liquid holding tank T is made of a suitable light-colored transparent plastic material, the contents of the tank, that is, the beverage, can be seen, so that a sales or exhibition effect can be obtained. The liquid reservoir T has an open abdomen 16, but the top of this is normally closed with a flat lid 17. The outer jacket 11 encloses all or part of a circulation pump means (not shown) for maintaining circulation and mixing of the beverage in the liquid holding tank T and a cooling unit (not shown) for cooling the beverage in the tank T. I support it.

A magnetic drive coupling device (not shown) between the pumps.

The cooling device usually consists of a compression/condensation device within the jacket 11, and an evaporator coil (not shown) that projects from the outside through the entrance at the bottom of the tank and into the beverage in the tank. The envelope 11 also includes a normally closed dispensing valve (not shown).

The connection of the valve is made at a position between the pot T and the blending valve 14, and the valve actuator 15 performs the valve actuator 15. The proportional mixing means provided in this application can be conveniently implemented in any beverage mixer or device.

provided, however, that the beverage mixer or device shall include a liquid holding tank or container in which the beverage is prepared, and shall also meet the need for periodic replenishment of the beverage holding capacity in the tank or container by introducing a predetermined volume ratio of water and concentrated beverage. A beverage mixer or device, such as: The proportional mixing device P shown in the drawing is
A suction means A, a water supply means W for guiding water to the means A, a valve means V and a switching means S for controlling the flow rate of water passing through the water supply means W, and a liquid concentrated beverage for the suction means A. It comprises concentrate delivery means C for guiding, beverage delivery means D communicating with and extending downstream from said means A, and bypass means B for controlling the operation of said means A.

The installation range of the plurality of means A, C, D, E, S, V and W, or the existence range of the parts or parts of each means, is the range of the rectangular block-shaped body B made of a suitable metal or plastic material. It's within.

The body B has flat top and bottom sides 20 and 21, flat front and rear sides 22 and 23, and flat right and left end or side faces 25 and 24. The suction means A comprises an elongated large diameter cylindrical suction chamber 30 having an inlet and an outlet or upstream and downstream ends 31 and 32, which are identical to the upstream end of the chamber 30 and extend from the upstream end in the rutting direction of the chamber. an elongated 4-diameter cylindrical water injection pipe line 33 extending to and having upstream and downstream units 34 and 35, and a lateral liquid or concentrate hole 36 (FIG. 6) communicating with the upstream unit of the chasoba 30; be.

The arrangement position of the suction means A is approximately at the center of the main body B, and the chamber 30 and the water injection pipe conduit 33 extend substantially horizontally and longitudinally of the main body, and their downstream ends are arranged at the right end surface of the main body. 25, their upstream ends are oriented toward the left side end surface 24 of the main body, and the holes 36
extends directionally the rear side 23 of the body.

A large diameter receiving chamber 40 in the body with which the downstream end of the chamber 30 communicates with a vertical cylindrical inner diameter 4 which enters the bottom side 21 of the body.
1 upper end.

The bottom side of the inner diameter 41 below the receiving chamber 40 is part or part of the beverage delivery means ○. What the means includes in addition to the inscription is an elongated, large, straight-protruding delivery tube 45, the upper end of which is directed upwardly and is screwed or otherwise ironed into the inner diameter 41. . The upstream end 34 of the injection pipe line 33 is connected to a vertically upward sekiguchi valve chamber 46.
Communicate downstream (of valve means V).

The extent of the chamber is defined within the body by the top side of the body. The bore 36 communicates with a horizontal forward extending concentrate inlet conduit 47 which enters the rear side of the body B of the means C.

Means C includes, in addition to conduit 47, a hose 48, preferably elongated and flexible.

It will be appreciated in the future that the hose 48 has a downstream end with a suitable connection or sealing connection to the conduit 47 and an upstream end that is lower than the downstream end and is adapted to enter the supplied liquid concentrate. Exactly as described. Having explained the structure so far, it is clear that the water is pressurized and the injection pipe line 33
When introduced into the upstream end and flowing through the conduit, a high velocity jet of water is directed longitudinally through the chasoba 30 from the upstream end of the chamber to the downstream end, and a negative pressure is This occurs in the upstream part of the chamber around this jet.

The negative pressure created at the upstream end of the chamber communicates with the bore 36 and the hose 48 of the means C, so that it performs the operation or function of drawing liquid concentrate from said concentrate source via the hose 48 and the bore 36. Combining and/or mixing of the concentrate flowing into the chamber 30 via the holes 36 and the jet of water flowing downstream through the chamber takes place.
When the water and concentrate are combined or mixed, the desired beverage is created. The concentrate thus formed freely flows into the chamber 40 from the downstream end of the chamber. chamber 4
The inflowing beverage flows unrestrictedly from inside the chamber in the downward direction into the tub T via the pipe 45 of the beverage delivery means D. A wide range of variations in the type of valve means V relating to and controlling the flow of water passing through the water supply means W may be made without departing from the spirit of the applicant's invention.

The valve means V in the example case is an electrically actuated, ie solenoid actuated, diaphragm-type shut-off valve incorporated into the body B.

In addition to the aforementioned closing valve chamber 46 which communicates with the water injection conduit 36 of means A, the valve includes a water supply conduit 51 which is present around the upper end of the chamber 46 and which enters the rear side surface 23 of the body.
an annular upward entrance inlet chamber 50 communicating with the chambers 46 and 50, a vertically oriented deflectable diaphragm 52 removably secured to the top of the body to ride over the diaphragm and hold it in place; This is a cap having an inlet/outlet type operating birch guide. Vertical displacement opening/closing operating rod 54
The arrangement is on the inside of the guide. Since a spring device (not shown) is installed during guidance, under normal conditions it flexibly holds the filler 54 and diaphragm 52 in the open position, thereby stopping the flow of water from the chamber 50 to the chamber 46. It will be done. Finally, the valve includes an electromagnetic coil device 55 that retains the pustules, is attached around the guide, and is activated when a voltage is applied to raise the operating valve opening/closing portion 54 upward, that is, to the open position.
, is. When a voltage is applied to the coil and the member 54 is lifted, the pressurized water in the chamber 50 is free to lift the diaphragm so that the water in the chamber 50 can flow into the chamber 46. In addition to the above, the valve means V may include a device for hydraulically balancing the diaphragm when the valve is in its normal state.

A detailed description of such device will not be given, as it does not constitute a direct infringement and/or part of Applicant's invention. It is clear from the said valve means that by opening and closing the valve it is possible to start and stop the flow of water into and through the structure, and that the execution of the valve actuation can be carried out by any suitable means such as the switching means S which will now be described. This is possible with a suitable switchgear.

It should be noted and is clear that the replacement of valve means V with the foregoing illustrations and explanations may be made without substantially infringing or departing from the spirit of applicant's invention. , with any one of a number of other common shapes and types of electrically operated valves, and if desired, the exchange may be performed with any one of a number of different types of common manual shut-off valves. , is quite possible. The bypass means E that controls the operation of the suction means A includes a branch pipe 60.
and the pipe line is connected to the chamber 40 at the downstream end of the chamber 30.
and the upstream end of the chamber 30, and communicates between the two. Means E next comprises a manually adjustable regulating valve arrangement N, which concerns and controls the gas and/or liquid flowing through line 60. When the valve device N is fully open, the flow through the conduit 60 is not restricted, so the internal pressure upstream of the chasoba 30 is approximately in equilibrium with the internal pressure of the chamber 40.

That is, the rate at which the negative pressure created in chamber 30 by the jet of water exiting injection tube line 33 draws liquid or gas from chamber 40 via line 60 is such that no effective negative pressure is generated in chamber 30'. Moreover, the concentrate chamber 30
The rate is such that there is no withdrawal via means C into it. As the valve device N is closed for the purpose of restricting the flow through the conduit 60, the negative pressure created in the chamber 30 increases (in the negative direction), so that via the structural means C the chamber 30
The ability to draw concentrate into the container increases approximately in proportion to the increase in negative pressure. Regarding the bypass means E, it is clear that if the negative pressure generated in the suction means A is controlled by adjusting the valve device N, the concentrate can be suctioned into the chamber 30 and mixed with the water flowing through the chamber. , as well as easy and accurate control of the proportional distribution of water and concentrate to formulate a structured dispensed beverage.

In the illustrative case, the valve arrangement N is of needle valve construction, and the elongated cylindrical valve chamber 70 it contains extends longitudinally into the body with respect to the body after entering the body rear side 25; One side of the chamber intersects and communicates with one side of the receiving chamber 40.

At the inner end of the chamber 70 is a ring-shaped tapered seat 71 that communicates with the passageway 60. Valve N then includes an elongated needle-type valve member 7
2 has an outer part 73 which is screwed to the outer part of the chamber 70 and can be inspected outside the main body B under normal conditions, and a seat which extends freely through the chamber and adjusts the liquid flowing through the valve side. There is a tapered tip 74 that matches the relationship with 71.

In practice, the valve member is fitted with a suitable seal 76 to seal the chamber 70 from the ambient atmosphere. The conduit 60 of the means E is concentric with the chamber 70 and the seat 71, and by extending inwardly from said chamber and seat, joins and communicates with the transverse branch conduit 61, which conduit Contact chamber 30'.

In other words, the conduit 60, the chamber 70, and the conduit 61 constitute a bypass path. The branch line 61 has the same D as the hole 36, and its position is on the opposite side of the hole 36 with respect to the chamber 30. The water supply means W includes, in addition to a conduit 51 entering the rear side of the main body and communicating with the chamber 50, ie, the inlet side, of the valve means V, an elongated water supply hose 56 having an upstream and a downstream end.

A suitable fitting 57 is fitted to the downstream end of the hose. The joint enters the rear side of the main body and is screwed into the joint receiving opening □, which connects to the conduit 51. The other or upstream end of the hose (not shown) provides an extension and suitable connection to a water outlet, or faucet, of a structural use or facility. In a preferred implementation of Applicant's invention, , the switching means S includes a liquid level reaction switch 80 and a manual master switch 8.
Contains 1.

Switch 80 is a float activated magnetically actuated reed switch as shown in FIG. 7 of the drawings. The switch 80 includes an elongated non-ferrous tubular gouge 82 whose lower end is closed and whose upper end is closed with a stopper 83 attached thereto, and an elongated tubular non-ferrous gouge 82 which is spaced parallel to each other within the gower and whose upper end extends through the stopper 83. A pair of elongated vertical non-ferrous elastic IJ nodes 84 and 84' are arranged to protrude to form terminals at the outer top of the probe.
It is. A contact point 85 is provided at the lower end of the lead.
The contact is normally open. 1 lead (lead 8
4') has an extension at its lower end, on which is a magnet 86.
Fix it appropriately.

Attach a ring-shaped non-ferrous float 87 to the outer circumference, and set T on the top and bottom.
Allows for free movement in the vertical direction of the search. The float 87 has an iron ring 88 attached to it. During implementation, if necessary, the movement of the float attached around the groping is restrained by providing a suitable stop 89 at the lower end of the groping.

The structure of the above switch is such that when the ring 88 is moved downward toward the bag and enters the radial plane at the same height as the magnet 86, the magnet is attracted in the direction of the magnet, so that the ring on the side where the magnet is attached is The structure is such that when the lead 84' moves toward the lead 84, the switch is closed.

The switch provided by the present application shall have a suitably wide operating range.

That is, the opening and closing of the saddle point is required only after the float 87 and its float 88 have moved a sufficient distance in the longitudinal direction for searching and in the relative direction for the magnet 86. This wide operating range is due to the fact that even when the switch is in the same open or closed position, there are various gaps between the magnet and the ring that create the magnetic field. The upper end portion of the groove 82 is inserted into the vertically penetrating hole □9 provided in the main body B.

In addition, each probe terminal is attached to the upper end of the lead, so it can be inspected from the top of the main body. The terminal of the switch 80 is the electric wire L
Connect to one leg of The electric wire is an electric wire that runs from the coil device 55 to a suitable outlet (not shown) in the place or facility where this structure is used.The other parts of the switch 80 can be suspended from the main body without restriction. do.

The parent control switch 81 is a simple manual toggle switch or the like, and is connected to the electric wire L in series with the switch 80. It should be noted that the installation can ensure that the power going to the coil device 55 is turned off or off, if desired or if necessary under the circumstances.
In addition, it shall be installed in such a way that it is possible to stop the operation of this structure. It should be noted that the arrangement and arrangement of the several conduits, chambers, and holes inside the body B may be easily and easily achieved by performing appropriate drilling and tapping operations. The arrangement and arrangement should be such that effective creation is possible.

The structure of the main body is suitable for mass production if an extrusion method or the like is used to create chasoba, pipes, holes, and/or passages therein. To further explain the invention of the present applicant, by attaching an inverted cup-shaped decorative cap 91 to the block-shaped main body, a horizontal valve V is formed at the top of the main body and protrudes upward from there. The switching means S is covered, and the switching means S is covered, and the front, rear, and side end surfaces of the main body are surrounded and covered.

In practice, and as shown, correct opening and closing is achieved externally by mounting the means S switch 81 within a convenient cap 91 and protruding the manual opening and closing actuator of the switch through the cap entrance hole. can be done.

In a preferred implementation of the present applicant's invention, the structure next includes a softener, rubber attachment part 92 provided at the bottom of the main body B, the purpose of which is to attach the beverage mixer M to the liquid holding tank. It is to be fixed to the top surface of the lid turtle 7. Lid 1
7 is provided with a closing port 93 for slidingly loosening the device mouth beverage delivery pipe 45, and a closing port 94 for slidingly ironing the recess 82 of the switch 80.

It is clear that the above relationship between the tube of the main body and the gouge relative to the lid 1T' allows the main body to be effectively held in place at the top of the lid for the tube and the gouge. be. When the tube 45 is closed to the closure 93,
It hangs down from the lid 17 into the inside of the pot T without being constrained, and ends within the range of the beverage held at the bottom of the tank. Also, search 8
2 is suspended from the search gate 94 of the lid 17, and is suspended into the tank and further into the beverage held in the pot without being restrained. Since in practice the storage of the feed concentrate is carried out in a suitable container located remote from the instrument, the upstream end of the suction hose 48 of means C extends into the container, i.e. into the feed concentrate in the container. .

In the illustrated case, the container for the feed concentrate is a glass bottle 100 placed on a shelf 101 below a counter 10, on which the instrument M is placed.

The bottle 100' has a stopper with a hole through which the upstream end of the suction hose 48 is inserted. hose 48
penetrates deeply into the bottle and terminates at the bottom of the bottle. In the actual case, since the position of the feed concentrate in the bottle 100 is a large distance from the bottom of the device P on the lid 17, a large hydrostatic neck pressure is created in the suction hose 48 in the device P.

Although the water head pressure inside the suction hose is large, the suction means A
is equal to or less than the negative pressure that can occur.

Therefore, when setting or adjusting the structure provided by the present applicant, first operate the means E to create sufficient negative pressure in the suction means A to overcome the hydrostatic head, and then the concentrated liquid will be Draw is performed upwardly from the bottle or concentrate source towards the suction means. Then, the negative pressure in the suction means A is increased by actuation of the means E. The degree of pressure increase is such that the flow rate and/or flow rate of the concentrate flowing through the suction means is such that the beverage flowing from the suction means into the chamber 40 and from there through the beverage delivery means D and into the cassette T reaches the target level. The degree of pressure increase is such that it is a drink with strength, that is, concentration. switch 80
The lower end of the saw 82 is suspended from the lid 17 into the beverage in the casserole T, but when it is suspended, a sufficient distance is taken so that it can be immersed in the beverage.

The degree of suspension penetration distance is such that the float 78 around the search is in the drink and is floating, and when the drink surface in the tank is at the apex, that is, the highest point, the position of the switch 80 and iron rod 88 is , due to the insufficient force acting between the magnet and the ring, the elastic lead 84' could not be held in the position where it moved, that is, shifted, causing the lead 84' to return to its normal open position. The position of the magnet 86 is such that it is vertically upward and away from the magnet 86, allowing it to return to and remain there. As the liquid level in the tank T falls, the iron ring 88 attached to the float 87 moves downward toward the magnet 86.
move in the direction. However, the time limit for movement is determined by the extent to which the gap between the magnet and the ring is reduced (the amount at which the magnetic field force is sufficient to bias the elastic reed 84 and move it to its closed position). , up to. By appropriately adjusting or changing the buoyancy of the float 87, for example by increasing or decreasing the effective cross-section of the float, it is possible to adjust the required travel distance of the float to open and close the switch 80. switch 80
By adjusting the operating range of the device as described above, it is easy and convenient to adjust and set the beverage to be prepared before using the device provided by the applicant for actual work and replenishing the stored beverages. Be practical. For example, assuming that the reservoir holds a minimum of 2 gallons of beverage, the degree of adjustment and setting of Applicant's device may be adjusted and set every time the beverage holding volume decreases by 3 quarts up to approximately 1 or 2 gallons, depending on the goal or required situation. It is possible to replenish the amount to such an extent that the In practice, at the upper end portion of the beverage delivery pipe 45, a portion higher than the beverage surface in the tank T is provided with a siphon action inhibiting ventilation opening 90 that extends horizontally with respect to the main body. The role of the Sekiguchi 90 is to fill the pipe 45 with the beverage, causing backflow of the beverage due to the siphon action, and causing the main body B,
The purpose is to prevent the water from flowing back into the bottle 100 through means C. It should be noted that in the case of the presently provided invention, the only operation required to be performed with respect to instrument M is to create tube and groin receiving holes 93 and 94 in reservoir lid 17.

If maintenance or cleaning of the instrument M is desired during the implementation, a lid 1 equipped with a device P provided by the applicant in connection with the instrument
7 can be easily and quickly removed from the tank T.

In addition, if it is desired to clean the proportional mixing device P individually or individually, and/or if the lid 17 needs to be cleaned separately, simply remove the float 87 from the receptacle 82 and then remove the main body. Remove the lid by lifting it up by hand, and then open the lid 17, that is, holes 93 and 9.
4. Just pull out the pipe 45 and the groove 82,
Easy and quick separation of the device P from the lid is possible.
In practice, a suction means such as the suction means A provided by the applicant provides effective operation even within a narrow pressure range.

Therefore, the suction means A can be designed to operate effectively even if the supply pressure of a particular water system is at or below normal values, or even if the supply pressure is the overwhelming majority. It is possible to achieve effective operation at certain low pressure values, which are much lower than the pressure range provided by the water system. In the latter case, and for effective operation of the applicant's invention, the water supply means W should be provided with a suitable pressure regulator R. In the case of the example, the regulator R is
It is shown in means W, in which it is connected to a water supply outlet W'. It should be noted, and it is clear from the foregoing, that considerable changes in the design of suction means A are possible, if desired, and that said means may be modified in substantially the same manner as means A, if desired or the circumstances so require. It is possible to replace it with a Venturi-type device that would function as described above and achieve the same goal end result. It should be further noted and evident that, if desired or the circumstances so require, without substantially infringing the novelty of or departing from the spirit of Applicant's invention, Substitution of other general types of float actuated switchgear may be implemented for the specific type of switch illustrated and described.

As is clear from the foregoing, the applicant has provided a new, simple, practical and effective device for automatically maintaining a full holding capacity of a non-carbonated beverage mixer reservoir with properly diluted beverages. and, by providing said apparatus, effectively eliminate and/or overcome a large number of disadvantages and undesirable problems which have long been associated with the daily operation and use of such instruments. or.

Although this description describes the typical form and application of only one example of applicant's invention, applicant's desire is not to be limited to the specific details set forth in this application, but rather to Applicant reserves the right to make any modifications and/or variations that may be apparent to those skilled in the art and that come within the scope of the following claims. A simple, practical, and effective device for automatically and intermittently mixing a predetermined small volume of water with a predetermined small volume of concentrated beverage and delivering the resulting mixture to a liquid holding tank of a beverage mixer, Requires the removal of the lid of the reservoir for the instrument's reservoir, which maintains a sufficient and readily available supply of water and beverages (from a remote and undefined source) at all times. Regardless of when it is temporarily added to the tank, the amount of unchilled liquid, i.e., beverage, that is added will warm up, or remove, the coldness of the existing beverage in the holding tank. If this is insufficient, at frequent intervals and as the situation requires, small amounts of water and concentrated beverage can be mixed and introduced into the blender reservoir.
