Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fixed-dose constant mixing control device, and more specifically, in a beverage vending machine, when mixing a diluted solution and a concentrated stock solution or raw material powder, the device controls the amount of mixing by timer control. This invention relates to a fixed-dose constant mixing control device configured to be able to adjust the ratio.

A undiluted solution such as concentrated fruit juice or fruit juice powder, etc., and a diluting liquid are stored in the housing, and the undiluted solution and the diluting liquid are mixed under advance control operation to prepare a mixed drink, which is then transferred to the beverage supply system. Beverage vending machines that sell beverages from the street are now widely used.

However, this type of vending machine has the disadvantage that it is not possible to obtain the desired taste and amount according to the customer's preference because the mixed drink mixed in a predetermined ratio is dispensed in a fixed amount. Ta.

Furthermore, it has been pointed out that the powder etc. and the diluting liquid are sold and supplied without being stirred and mixed uniformly, resulting in a concentration difference in the beverage itself.

As a result of intensive research and efforts to overcome the various problems described above, the inventors of the present invention have found that, for example, the unit dispensing amount of a mixed drink to be sold is variably controlled by the dispensing time of the diluting liquid. It has been found that the above-mentioned problems can be overcome by controlling the mixing ratio of raw materials such as powder and diluent by controlling the release time of the powder.

In addition, if the discharge time of raw materials such as powder is set shorter than the pouring time of the dilution liquid, stirring and mixing can be performed uniformly and reliably.
It was discovered that there was no difference in concentration between the mixed drinks themselves.

Therefore, the object of the present invention is to provide a fixed-quantity dispensing mixing device for mixing and supplying a diluting solution and a concentrated stock solution or a raw material powder, whether the diluting solution and the concentrated stock solution, etc. The system is configured so that the continuous pouring amount is an integral multiple of the unit pouring amount without changing the mixing ratio with The object of the present invention is to provide a fixed-quantity dispensing mixing device that supplies a desired fixed-quantity dispensing fixed-mixing mixed beverage.

For this purpose, the present invention provides a mixed beverage dispensing device that stirs and mixes and discharges a diluted liquid and a concentrated stock solution or raw material powder, which comprises a diluting liquid tank, a raw material tank, and an agitating mixer. A diluent pouring solenoid valve is provided in the diluent supply pipe led out from the liquid tank, and the diluent pouring solenoid valve is opened and closed by a time-adjustable diluent regulating relay device, and a raw material discharge mechanism is installed in the raw material tank. The object of the present invention is to provide a fixed amount pouring mixing control device which incorporates a raw material discharge mechanism and is configured to control the operation of the raw material discharge mechanism by a time-adjustable raw material metered discharge relay device.

In addition, in this quantitative dispensing constant mixing control device, if the operation time of the raw material constant dispensing relay device is completed before the operation of the diluent liquid regulating relay device is completed, a suitable effect is produced in the stirring action, etc., and the diluent liquid is The regulating relay device consists of a relay connected to the power supply in series with a normally closed contact cooperating with a first delay relay that is activated simultaneously with the starting switch, and the material metering relay device consists of a relay that is connected to the power supply in series with a normally closed contact that cooperates with a first delay relay that is activated simultaneously with the starting switch. a relay connected to a power source in series with a normally closed contact cooperating with a two-delay relay and in parallel with the relay of the diluent adjustment relay device; A series body including a normally open continuous dispensing switch and a normally closed contact of the first delay relay is connected in series to the parallel body of relays, and the diluent adjustment device is connected in parallel to the series body. Since the normally open contact of the relay of the relay device is connected, continuous dispensing of a fixed amount is possible, and even if the continuous dispensing switch is turned off during continuous dispensing, unit fixed dispensing will continue. A special effect is produced by being able to pour out an integral multiple of the pouring amount and at a constant mixing ratio.

Next, the fixed amount pouring constant mixing control device according to the present invention will be described in detail using a coffee vending machine as an example, with reference to the accompanying drawings.

In FIG. 1, a coffee vending machine implementing the device of the present invention is basically composed of a raw water tank 10 and a raw material tank 12.

The raw water tank 10 is made of a rectangular metal body, a hot water discharger 14 is connected to the side wall, and a water supply pipe 1 for supplying raw water is connected to the raw water tank 10.
6 has been introduced.

A float 18 for detecting the water level in the tank is disposed inside the raw water tank 10, and the tip of a float lever 20 of the float 18 passes through an opening in the side wall and connects to a dry firing prevention micro switch 22 and a water volume adjustment micro switch. '/-1-
It will take place between 23 and 23.

A dry-firing prevention thermometer 24 is provided below this water volume adjustment microswitch 23, and this thermometer 24 is connected via a conductor 26 to a sensor 30 placed in contact with a heater 28 provided on the inner side wall of the raw water tank 10. be done.

Note that a hot water well control thermometer 32 is attached to a substantially central portion of the curved heater 28.

A small hole is bored in the upper side wall of the raw water tank 10 from the heater 28 attachment part, and a raw water supply pipe 34 is led out from this small hole, and the raw water supply pipe 34 is communicated with the mixer ball 38 via the raw water supply valve 36. ing.

A raw material tank 12 filled with the above-mentioned coffee powder and incorporating a powder discharge mechanism 39 described later is disposed above the mixer ball 38, and a cup or decanter saucer 40 is arranged below the raw material tank 12.

Note that reference numeral 42 indicates an overflow pipe, 44 a drain pipe, and 46 a steam vent hole drilled in the earthen wall of the raw water tank 10.

Furthermore, as can be easily understood from FIG. 1, an exhaust duct has a built-in filter 48 for moisture-proofing the coffee powder in the raw material tank 12 from steam generated from heated coffee supplied to a sales outlet (not shown). 50 and an exhaust fan 52 for forcibly exhausting moisture discharged from the exhaust duct 50, a favorable effect can be obtained.

Next, the hot water discharge mechanism 14 that pours out hot water at an appropriate humidity from the raw water tank 10 and the powder discharge mechanism that is built into the raw water tank 12 and discharges coffee powder are operated by a relay device, a solenoid valve, and a drive motor. The coffee to be sold is guaranteed to have a predetermined amount and a predetermined strength (that is, a fixed mixing ratio), and the electrical control mechanism thereof will be explained in detail below with reference to FIGS. 2 and 3.

This device can be suitably implemented by adopting the electrical configuration shown in FIG. 2, for example, where S is a power switch, F is a fuse, L1 is a power indicator light, S2 is a water level switch (corresponds to the water volume adjustment microswitch 23 in Fig. 1), W■, is a water supply valve, and S3 is a dry-firing prevention switch (corresponding to the dry-firing prevention microswitch 22 in Fig. 1).
), Th1 is the temperature control thermometer (corresponds to the hot spring control thermometer 32 in Figure 1), Th2 is the dry firing prevention thermometer (corresponds to the dry firing prevention thermometer 24 in Figure 1), and Hi is the heating heater (corresponds to the hot spring control thermometer 32 in Figure 1). (corresponds to the heater 28 in the figure), Th3 is the appropriate temperature indicating thermo, L2 is the appropriate temperature indicating lamp, S4 is the holding heater switch, H2 is the keeping mixing heater, PB2 is the hot water pouring switch, FM is the exhaust fan shown in Fig. 1. 52, most of these electric elements operate as is clear from the operation time chart in FIG. Further explanation will be omitted.

Next, the operation of the fixed amount dispensing/mixing control device of the present invention will be explained in detail. For dispensing a fixed amount, first, the fixed amount dispensing switch (starting switch) is pressed.

By suppressing this switch PBt, the mini power relay
is activated, the normally closed contact X1 is closed, and even if PBt is in the OFF state, the mini power relay X1 is self-held.

Therefore, the normally open contact X13 closes, the solenoid valve W2 built into the hot water discharge mechanism 14 opens, and hot water heated to an appropriate temperature in the raw water tank 10 is poured into the mixer bowl 38.

At the same time, the mini power relay
1 is closed, the geared motor M incorporated in the powder discharge mechanism 39 is driven to rotate, and the coffee powder filled in the raw material tank 12 is discharged into the mixer pole 38.

The hot water flowing in from the side of the funnel-shaped mixer ball 38 rotates in a spiral shape and quickly stirs and mixes the coffee powder, which is then sold into cups or the like through a sales port provided at the bottom of the mixer ball 38. Poured out.

The powder quantitative adjustment delay relay TM2 operates when the set time is reached, and the normally closed contact opens to disable the mini power relay X2.

Therefore, the normally open contact X21 returns to its original state, and the geared motor M stops driving, completing the discharge of the coffee powder.

Although it differs depending on the powder/liquid other than coffee powder and the mixing ratio, when this guard motor M stops, the raw water pouring amount adjustment delay relay TM1 is activated, the normally closed contact TM1 is opened, and the mini power relay X1 is activated. The self-retention is released, the solenoid valve W2 is closed, and the quantitative dispensing of one unit (one cup) is completed (see Fig. 3).

This pouring amount per unit can be obtained by adjusting the set time of raw water pouring amount adjustment delay relay TM1, and the concentration, that is, the mixing ratio, can be obtained by adjusting the delay relay TM2 for adjusting powder metering amount. If the set time is configured to be variable, it is possible to obtain a coffee beverage that suits one's taste.

In particular, when stirring and mixing, by deenergizing the raw water output adjustment delay relay TM1 with a slight delay after the geared motor stops, the powder raw material injected into the mixer pole is reliably discharged without remaining in the mixer ball. This not only prevents the inside of the mixer bowl from becoming dirty and unsanitary, but also prevents the constant mixing ratio from being changed by remaining powder.

To further explain continuous dispensing, when the continuous dispensing switch S5 is turned on, the mini power relay X1 is activated through the normally closed contact of the delay relay TM1, and the normally open contact X11 is activated.
is closed and the mini power relay X1 enters a self-holding state.

As a result, the normally open contact X13 is closed and the solenoid valve WV2 is opened to guide hot water from the raw water tank to the mixer pole, and thereafter the same operation as one unit quantitative discharge is performed.

By the way, in the case of continuous dispensing, the raw water dispensing amount adjustment delay relay TM1 and the powder metering adjustment delay relay TM2 connected in series with this switch S5 are operated in the same manner as explained in the unit metered dispensing completion operation. However, since the switch S5 is in the ON state, the mini power relay X1 is operated again through the normally closed contact TM1, and the above-described quantitative dispensing operation is repeated.

Note that during continuous dispensing, switch S
Even if 5 is turned off, since the mini power relay X1 is self-held by the normally open contacts X and 1, the continuous dispensing will not be completed unless the dispensing of the fixed amount is completed.

Therefore, even if the switch S5 is turned off at any point in time, it is possible to dispense an integral multiple of the unit quantity dispensed at a constant mixing ratio.

As described above, according to the fixed amount dispensing fixed mixing control device of the present invention, the amount and mixing ratio can be adjusted according to the customer's preference, especially in a mixed drink vending machine, and moreover, it is possible to sell by continuous dispensing. Even when mixing is carried out, the mixing ratio is always constant, which is very convenient for customers.

In addition, the supply amount and mixing ratio of the mixed beverage can be easily configured and manufactured at low cost by using the raw water output amount adjustment delay relay TM1 and the powder quantitative adjustment delay relay TM2, which are configured to allow time adjustment. However, it has the advantage that it can be configured to perform reliable operation.

As mentioned above, the present invention has been described in detail with reference to preferred embodiments, but the present invention is not limited to these embodiments, and can be used for devices other than coffee beverage vending machines. Of course, various improvements and design changes can be made without departing from the spirit of the invention.
