6 is a perspective view for explaining a raw material mixing device according to the present invention, and the description thereof will be omitted while attaching the same reference numerals to the same parts as the conventional structure.

That is, since the structure of the general vending machine is the same as the conventional structure described above with reference to FIGS. 1 to 3, a description thereof will be omitted. Hereinafter, the raw material mixing device 400 will be described in detail with reference to FIGS. 6 and 7. Let's do it.

The raw material mixing device 400 of the present invention is installed inside the main body 100 in order to mix raw material powder discharged from the raw material container 112 shown in FIG. 1 and water discharged from the water supply container 111. .

Here, as shown in FIG. 6, the raw material mixing device 400 includes a first raw material mixing container 411 in which water discharged from the water supply container 111 and coffee raw material discharged from the coffee raw material container 112 are contained. ), A second raw material mixture container 421 to contain the water discharged from the water container 111 and the domestic container material discharged from the domestic container material 112, and the water discharged from the water container 111; Consists of a third raw material mixing cylinder 431 to contain the juice raw material discharged from the juice raw material container 112.

In addition, the raw material mixing device 400, the first rotary blade 413 to be installed in the first raw material mixing cylinder 411, and the second rotary blade to be installed in the second raw material mixing cylinder 421. 423, and the third rotary blade 433 to be installed in the third raw material mixing cylinder 431.

In addition, the raw material mixing device 400, the power transmission means for integrally transmitting the power of the motor described later to the first rotary blade 413, the second rotary blade 423 and the third rotary blade 433. 440 and one motor 450 coupled to a predetermined portion of the power transmission means 440 are also included.

Here, the power transmission means 440 is to be coupled to the first rotary blade 413, the second rotary blade 421 and the third rotary blade 433, respectively, as shown in FIGS. Rotating shafts 441, 442 and 443, rack gears 445, 446 and 447 that are coupled to the ends of the rotating shafts 441, 442 and 443, and the rack gears 445 and 446. (447) and the timing belt 448 to be integrally coupled, one end is coupled to any one of the rack gear 446 of the plurality of rack gears (445, 446, 447) and the other end is The motor shaft 449 is configured to be coupled to the motor 450.

Therefore, when the user of the vending machine inserts a coin to receive a beverage such as coffee, and then presses the selection button of the beverage selection unit 213, the cup stored in the cup box 113 is stored in the cup housing ( 115).

When the cup is supplied into the cup housing 115, the coffee raw material powder stored in the coffee raw material container 112 and the hot water stored in the water supply container 111 are discharged into the first raw material mixing container 411.

In addition, when the coffee raw material and the water is contained in the first raw material mixture 411, the motor 450 is driven by a signal from the control unit, the driving force of the motor 450 is driven by the motor shaft 449 The second rack gear 446 shown in FIG. 8 is transferred.

At this time, when the second rack gear 446 starts to rotate by the rotational force of the motor shaft 449, at the same time, the first rack gear 445 and the third rack gear 447 connected to the timing belt 448 at the same time. ) Is rotated, and the rotational force is transmitted to the rotational shafts 441, 442 and 443 so as to rotate each of the rotary blades 441 and 442 coupled to the rotational shafts 441, 442 and 443. Rotated.

Accordingly, the first rotary blade 441 is rotated by the power transmission device 400 so that the coffee raw material and water contained in the first raw material mixing cylinder 411 are mixed.

Then, when the coffee raw material and water contained in the first raw material mixture 411 is completely mixed, the coffee beverage is a predetermined amount into a cup located in the cup housing 115 through a beverage discharge nozzle (not shown) When discharged by the user, the user can purchase a drink dispensing is complete through the drink inlet 214.

On the other hand, even if the user selects a domestic tea beverage or juice beverage according to your preference, the beverage mixing device 400 operates the same as the above-described sales of coffee beverages, so the description thereof will be omitted.

Accordingly, when the user purchases a drink, as shown in FIG. 6, the motor 450 driven to mix the raw material powder and the water has a power transmission means on the plurality of raw material mixing cylinders 411, 421, 431. 440, only one of the raw material mixing device 400 of the present invention, as shown in Figure 4, the motor 312, 322, 332 is driven to mix the raw material powder and water as shown in FIG. Compared to the conventional raw material mixing device 300, which is separately installed for each of the plurality of raw material mixing vessels 311, 321 and 331, manufacturing cost is reduced and space utilization inside the main body 100 is enhanced.

As described above, according to the present invention, only one motor is installed in a plurality of raw material mixing cylinders via a power transmission device, so that the user is driven to mix raw material powder and water when the user purchases a beverage. As well as the cost savings, this increases the space utilization inside the main body, thereby increasing the merchandise.
