Description

Stirring Mechanism for Vending Machines

The present invention relates to an agitator mechanism for a vending machine mixing ball, and more particularly, to an agitator mechanism for a vending machine mixing ball for smoothly mixing raw materials and water in a vending machine that sells hot beverages, thereby improving the commerciality of the beverage.

1 is a front view showing the arrangement of major components inside the vending machine.

In general, the main operation of a vending machine selling hot drinks is a raw material container (1) for separating and storing domestic tea, coffee, cream, sugar, etc., and a water container (2) for storing drinking water for liquefying raw materials in powder form. And a hot water tank 3 for maintaining the water from the water tank 2 at a constant temperature, and a mixing ball 10 for mixing a raw material and hot water to form a beverage. Each dispensing motor is installed in a raw material container 1 such as domestic tea, coffee, sugar, or prim.

With this configuration, when the user selects a predetermined beverage from the operation panel in front of the vending machine, for example, if a coffee beverage is selected, the electric valve of the hot water container 3 is turned on to supply a predetermined amount of hot water to the mixing bowl 10. At time intervals, the mixing motor and the ejection motor are also turned on in turn. The coffee is sent out from the raw material container (1) in the order of prim, coffee, sugar and mixed in the mixing bowl (10), the coffee is put in a cup in the delivery container (5).

In FIG. 2, the mixing ball 10 is composed of a cover 11, a body 12, a shaft 13, and the like, and an upper disk 14 and a lower disk 15 are installed on the shaft 13. At this time, the lower disk 15 has a function of removing bubbles generated when mixing the raw materials, but because of the synergistic action of the water flow in accordance with the high-speed rotation, the conventional vending machine is the accumulation and entanglement of the raw materials in the mixing ball 10 Of course, the raw material is discharged in the undissolved state, which lowers the commercial value of the beverage. Accumulation of raw materials requires a lot of time for hygiene control and cleaning of vending machines.

Accordingly, an object of the present invention is to provide an agitating mechanism for a vending machine mixing ball that improves the commerciality of beverages by smoothly mixing raw materials and water in a vending machine selling hot drinks.

In order to achieve this object, the present invention provides a vending machine having a mixing ball 20 to which an upper disk 24 and a lower disk 25 are fixed for smooth stirring of raw materials and water on a shaft 23. (24) and the lower disk 25 is provided with a stirring mechanism for the vending machine mixing ball, characterized in that fixed to maintain a predetermined angle of inclination so as not to be orthogonal to the shaft (23).

At this time, the upper disk 24 and the lower disk 25 is inclined to have a slope in the opposite direction.

Hereinafter, with reference to the accompanying Figure 3 will be described in detail a preferred embodiment of the present invention.

The present invention is applied to the vending machine having a mixing ball 20 is fixed to the upper disk 24 and the lower disk 25 for smooth stirring of the raw material and water on the shaft 23, the body 22 and the cover ( In the mixing ball 20 having a structure sealed by 21, the shaft 23 disposed at the center of the body 22 is rotatably fixed on the cover 21. A motor is connected to the shaft 23 to the upper side of the cover 21, and a pipe for delivering a beverage to the discharge container 5 is connected to the lower part of the body 22.

In FIG. 3, according to the present invention, the upper disk 24 and the lower disk 25 are fixed while maintaining a predetermined inclination angle so as not to be perpendicular to the shaft 23. The upper disk 24 and the lower disk 25 are press-fitted on the shaft 23 with the same inclination angle. The larger the inclination angle of the upper disk 24 and the lower disk 25, the larger the stirring effect according to the present invention, but the body 22 of the mixing ball 20 is unnecessarily large and the required torque of the motor is also determined through various experiments . It is also noted that an increase in the rotational torque of the motor causes an increase in vibration and noise.

At this time, the upper disk 24 and the lower disk 25 is inclined to have a slope in the opposite direction. As shown in the figure, the upper disk 24 and the lower disk 25 are arranged not to be parallel. Even if the lower disk 25 rotates at high speed, the lowering motion of the water is smoothed. That is, as shown in the lower disk 15 of FIG. 2, the flow of water can be increased to eliminate the phenomenon of preventing mixing of water and raw materials. When the upper disk 24 and the lower disk 25 have the inclination in the opposite direction with respect to the horizontal line, the stirring effect is larger than when having the inclination in the same direction.

On the other hand, it is advantageous to shape the inclined upper disk 24 and the lower disk 25 into an elliptic structure so that the shape projected in the direction of the rotational axis becomes a circle, which reduces rotational unbalance. If the projected shape does not form a circle, the gap with the side wall of the body 22 becomes large, so that the descending speed of the water becomes inadequate, resulting in poor stirring of the water and the raw material. In addition, the rotational unbalance of the shaft 23 is a factor to increase the vibration, noise of the mixing ball (20).

Stirring mechanism for a vending machine mixing ball of the present invention having the above configuration and action has an effect of improving the commerciality of the beverage by smoothly mixing the raw material and water in the vending machine selling hot drinks.
