The present invention relates to a water supply device of a beverage vending machine, and in particular, a rotary mixing water supply device of a beverage vending machine, which is capable of mixing raw materials and water inside a product by rotating a mixing blade by a rotational force of a motor, while easily supplying hot water. It is about.

In general, a beverage vending machine that sells coffee or domestic tea in which raw materials are embedded, when the user presses a product selection button after inserting a coin into a coin inlet as shown in FIG. The product 300 pushes the product of the product loading rack 200 to the push rod 310 of the product dispensing device 300 to discharge the product to the product discharge port 220 in the front lower part.

At this time, the user withdraws the product from the product outlet 220 and removes the lid of the product by a certain length, and then it is fixed to the water cup nozzle 110 of the water supply nozzle 110 provided in the center of the main body (1) When the 430 is inserted into the micro switch 230 of the cup fixing guide 430, the water supply control valve of the heater tank 100 is controlled by a control unit (not shown) inside the main body 1. As the 120 is opened, water is supplied to the water supply nozzle 111 through the water supply hose 110 to supply hot water into the product.

In addition, when a predetermined amount of hot water is supplied into the product, the user withdraws the product from the cup fixing guide 430, and the micro switch 230 turned on by the product is returned to its original position and then turned off again. OFF), the water supply control valve 120 of the heater tank 100 is blocked by the operation of the control unit (not shown) inside the main body 1 to stop the water supply.

However, in this method, after the user withdraws the product from the product outlet 220 in order to receive hot water, the user directly removes the lid of the product by a predetermined length and supplies the water supply nozzle 110 of the water inlet 210 again. The cup fixing guide 430 on the side should be supplied with hot water, so it is inconvenient to use and cumbersome, and the product is drawn out of the cup fixing guide 430 so that the contents and water are not sufficiently mixed with a separate rod or tool. If not, there was a problem that the residue of the contents remain at the bottom of the container.

In addition, as shown in Japanese Patent Laid-Open No. 62-247494 and Japanese Patent Laid-Open No. 62-239296, there was a thing that can be stirred with a stirring blade by putting the contents in a cup. After positioning, press and hold several contents as desired, supply water, and stir by lowering the stirring blade shaft connected to the motor. The stirring blade (1) is moved from the upper standby position to the bottom of the cup (10) by 20 mm. Descending at a rate of mm / sec, and then stopping descending for 2-3 seconds at a position of about 5 mm from the bottom of the cup, continuing the stirring rotation, then raising to a three-way position at a rate of 150 mm / sec and stirring for a short time The diameter D of the stirring blade 1 is set to D = (0.6-0.75) × d with respect to the bottom diameter d of the cup 10, and the twist angle Θ of the stirring blade 1 is Θ = 30 °- 45 ° to reduce liquid rise And there is one so designed to prevent scattering of the liquid during stirring.

However, this structure is inconvenient to use and cumbersome because the user has to operate and check the operation buttons one by one.

Accordingly, an object of the present invention is to provide a rotary mixing water supply device for a beverage vending machine that allows hot water to be easily supplied and the raw material and water are sufficiently mixed in the product by the rotation of the mixing blade by the rotational force of the motor.

In other words, the object of the present invention is to provide a solenoid ejector to perform the up and down linear reciprocating motion, the mixing wing is provided to be mixed by the rotation of the drive motor and at the same time to supply hot water from the water supply hose This is achieved by having a water supply connection pipe, which is intended for user convenience.

An embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic view of a beverage vending machine according to the present invention, Figure 2 is a cross-sectional view showing the configuration of the present invention, it is located in the front center of the inside of the main body 1 to perform the up and down straight reciprocating movement on the top A solenoid fixing bracket (3) is connected to the solenoid ejector (2) and the rod (20) of the solenoid ejector (2) and interlocked in a linear reciprocating motion according to the operation of the solenoid ejector (2). The motor fixing bracket 4, which is screwed to the bracket 3 to fix the driving motor 40 at the center, and the rotating shaft 50 and the mixing shaft 60 of the driving motor 40 at the lower portion thereof. A shaft connecting connector (5) for connecting is provided, and the shaft connecting connector (5) has a water supply passage (60) to surround the mixing shaft (60) to the outside and to supply hot water from the water supply hose (110) on one side. Cylindrical water supply pipe In addition, the mixing blade (60) is fixed to the mixing shaft (60) at the front end of the mixing shaft (60) so that the mixing (mixing) can be made smoothly by the rotation of the driving motor (40). Combined.

Referring to the effect of the present invention configured as described above are as follows.

When the user presses a product selection button after inserting a coin into the coin inlet, the product of the product loading rack 200 is moved to the pusher 310 of the product dispensing apparatus 300 by the operation of an internal control unit (not shown). When the product is discharged, the product is inserted and fixed vertically to the cup fixing guide 430 through the product guide 400, and at this time, the contact is in contact with the micro switch 420 at the bottom to check whether the product is discharged. The solenoid ejector 2 is operated by the operation of the part (not shown) so that the solenoid fixing bracket 3 is interlocked together so that the water supply connection pipe 6 of the lower part is inserted through the upper part of the lid of the product. In connection with this, the water supply control valve 120 of the heater tank 100 provided in the upper part of the main body 1 is opened to supply hot water into the product through the water supply connection pipe 6 through the water supply hose 110. On the motor fixing bracket (4) Is driven with a positive coupling the drive Motor 40 is that the mixing shaft (60) equipped in the water supply connection pipe 6 to be rotated.

Accordingly, the mixing blade 7 provided at the front end of the mixing shaft 60 is rotated to sufficiently mix the raw material and water in the product.

In this way, when a series of cycles of the control unit passes, the power supply of the solenoid ejector 2 and the power supply control valve 120 are cut off, and the solenoid fixing bracket 3 of the spring 21 of the solenoid ejector 2 is cut off. While returning to the original position with a restoring force, the water supply connection pipe 6 is moved upward together, and the driving motor 40 also stops the rotation to complete a series of hot water supply and mixing, and the user fixes the cup. The product may be withdrawn from the guide 430.

As described above, the present invention allows the hot water to be supplied directly after the product is dispensed, so that the product is withdrawn from the product outlet for hot water supply, and the product is removed from the product outlet and inserted into the cup fixing guide of the water supply nozzle. It can alleviate the inconvenience and hassle of use, and prevent the residue of raw material from remaining inside the product by mixing the raw material and water inside the product with the mixing blade by the rotation of the driving motor together with the hot water supply. It is a very useful design that can be done.
