The present invention relates to an impeller structure of a mixing housing for a beverage vending machine, and more specifically, an impeller that acts to pass a mixture of beverage powder (coffee, domestic tea) passed through the mixing ball according to the supply of raw materials to the mixing housing with water. By improving the shape structure of the to ensure efficient mixing in a shorter time to provide a delicious coffee.

In general, vending machines are installed and operated in appropriate places such as rest rooms, restaurants, and streets so that beverages can be taken in a simple way.

The vending machine, which is released and operated in a small size as the beverage vending machine, is representative of coffee and domestic tea vending machines.

The beverage vending machine is installed in the front plate (3), the mixing ball (2) receiving the beverage powder is supplied and passed from the raw material input container (1), as shown in Figure 1 attached to the main part of the beverage vending machine, the mixing ball The mixing housing 4 is connected to the lower side of the (2).

The mixing bowl (2) is supplied with hot water from one side together with a predetermined amount of beverage powder to be supplied, the mixing housing (4) mixes the beverage (raw material) supplied with water from the mixing bowl (2) , The discharge port (4a) for discharging it is provided, the mixing impeller (5) therein is installed in a structure that rotates in accordance with the drive of the motor (M) installed on the outside of the rear of the mixing housing (4).

As shown in FIG. 2, the impeller 5 is provided with a coupling groove formed in the cylindrical body 5a so as to be coupled to the rotating shaft of the motor M from one side, and a plurality of main wings 5 around the outer periphery thereof. -1) and the auxiliary wings (5-2) are formed at a predetermined interval.

The mixing housing 4 has an inclined portion of the front plate 3 inclined so that the impeller 5 rotates water and beverage powder introduced from the mixing ball 2 by driving the motor M. Falling on the secondary blade (5-2) of the primary mixing is made at the same time secondary mixing is made on the main wing (5-1) side to discharge the mixed beverage through the outlet (4a).

However, the impeller 5 as described above has a structure in which two main wings 5-2 are formed of two main wings 5-1, and substantially two beverages are properly mixed in the two auxiliary wings and the main wings. There was a disadvantage not to lose.

This has a gap between the auxiliary wing 5-2 and the main wing 5-1 because the body 5a is cylindrical. Since the blade has a cross-sectional area, the mixing efficiency of the beverage mixture temporarily impregnated in the mixing housing and passed through the impeller having the above structure in a short time is poor.

Mixing of the beverage mixture is done, but more time is required for more effective mixing, but due to the vending machine's condition, the mixing is not performed well within the short time that the beverage mixture passes through the mixing housing. There was a problem that the discharge through is not smooth.

In particular, beverage mixtures containing a large amount of powdered grains such as domestic tea are not only tasted less when discharged under poor mixing conditions but also gradually accumulate in the mixing housing. It was a factor to block the outlet of the.

The present invention has been made to solve the above-mentioned problems, the shape structure of the impeller acting to pass through the mixing of the beverage powder (coffee, domestic tea) passing through the mixing ball to the mixing housing in accordance with the supply of raw materials and water The purpose is to improve the quality of the coffee in a shorter time with the efficient mixing and discharged to provide a delicious coffee.

According to the present invention for achieving the above object, a mixing ball supplied and passed from the raw material input container to receive the beverage powder is installed on the front plate, the mixing housing is connected to the lower side of the mixing ball is installed, mixed inside the mixing housing In the impeller is installed in a structure that rotates in accordance with the drive of the motor installed on the outside of the rear of the mixing housing to discharge the beverage mixture through the outlet of the mixing housing,

The impeller is provided with a plurality of stirring blades protrudingly formed on the outer periphery of the cylindrical body, while being inclined so as to rotate and mix the beverage mixture in the direction of the screw, guide the beverage mixture to the stirring wing side with the diameter of the outer peripheral body from the stirring blade The screw protrusion is characterized in that formed integrally extending along the longitudinal direction.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

3 is a perspective view illustrating the impeller according to the present invention, FIG. 4 is a front view illustrating an operating state of the impeller according to the present invention, and FIG. 5 is a side view illustrating an operating state of the impeller according to the present invention.

In the present invention, the mixing bowl 12 is fed to the raw material input container 11, passes through the beverage powder 12 is installed on the front plate 13, the mixing housing 14 is connected to the lower side of the mixing bowl 12 In the mixing housing 14, the mixing impeller 15 is installed in a structure that rotates in accordance with the driving of the motor (M) installed on the outside of the rear of the mixing housing 14, the outlet of the mixing housing 14 side In discharging the beverage mixture through (14a),

The impeller 15 is provided with a plurality of stirring blades 15-1 protrudingly formed on the outer circumference of the cylindrical body 15a, while being inclined to rotate and mix the beverage mixture in the screw direction. The screw protrusion 15-2, which guides the beverage mixture to the stirring blade side from the diameter of the outer circumference of the body from 1), is integrally formed along the longitudinal direction.

In the figure, reference numeral 14b denotes an inlet for the beverage mixture of the mixing housing to be supplied from the mixing bowl.

Referring to the operation and effect according to the impeller structure of the mixing housing for the beverage vending machine of the present invention having such a structure as follows.

First, the order of supplying, mixing, and discharging beverages through the beverage vending machine is the same as in the related art.

When the selection button of the beverage through the small beverage vending machine is determined, the beverage powder is supplied from the raw material input container 11 according to the set signal, and passes through the mixing ball 12 installed on the front plate 13 side through the set signal. The supplied beverage powder and hot water supplied from one side are discharged through the outlet 14a of the mixing housing 14 through an appropriate mixing process through the mixing housing 14 installed on the lower side of the mixing ball 12 and separately provided. The beverage is provided in a disposable cup (not shown in the figure).

The beverage mixture that passes through the inlet 14b of the mixing housing 14 is instantaneously mixed according to the rotation of the impeller 15 by the operation of the drive motor.

The beverage mixture which is temporarily charged into the mixing housing 14 and exits through the outlet at the same time is filled in the rotation of the impeller 15, and the screw protrusion 15-2 formed in the longitudinal direction of the body 15a is a beverage mixture. The basic mixing is made while serving to guide the stirring blade (15-1) side direction.

As described above, the beverage mixture is rotated in a screw manner and is naturally moved to the stirring blade 15-1 at the point where the formation of the strut protrusion 15-2 ends, and the outlet 14a of the mixing housing 14 is moved. The stirring blade 15-1 before exiting the mixing mixture in the spiral direction and at the same time serves to help easily exit to the outlet (14a) side.

As described above, the present invention has a shape structure of the stirring blade and the screw protrusion of the impeller, in particular, the mixing of the drink mixture having a low mixing ratio, such as domestic cars, is made more efficient than the conventional impeller, so that it can be easily discharged to the outlet Thus, within a short time with the beverage selection and to facilitate the discharge of the beverage is provided.
