The present invention relates to a vending machine, and in particular, including a second partition installed in the inner space so that the first space portion and the second space portion is formed, wherein the cold water tank and the hot water tank are arranged in parallel in the first space portion. In the second space part, a cooling device is arranged, and the cold water tank and the hot water tank are arranged in parallel to maintain the vending machine compactly, and the hot part of the cooling device and the cold water tank and the hot water tank are separated to minimize heat loss. And vending machines that can serve hot and cold drinks at the same time.

Conventional vending machines are those presented in Korean Patent Laid-Open Publication No. 2005-0035063.

In general, the food vending machine is installed in the material container and the material container for storing the materials, and is mounted on the material container shelf and the material container shelf to support the material container in the case and the screw for discharging the material stored in the material container to drive the screw. A motor for doing so is provided. The installation structure of the material container shelf of such a food vending machine is shown in FIG.

1 is a side cross-sectional view for explaining the installation structure of the material container, material container shelf and motor of the conventional food vending machine.

1 shows an internal structure of a conventional food vending machine. As shown, the food vending machine 100 includes a vending machine case 110. Inside the vending machine case 110, a material container 120 for storing materials is provided. Before and after the lower end of the material container 120, protrusions 122 are formed to be detachable from the material container shelf 150.

The material container 120 is equipped with an ejector 130 disposed through the lower part of the material container 120 in order to discharge the material inside the material container 120 to the outside. A screw is suitable as the ejector 130. The ejector 130 is connected to the connection 132 for receiving the power of the ejector driving means 140 described later. The connection part 132 is exposed to the back of the material container 120.

The material container shelf 150 on which the material container 120 is installed is integrally fixed to the vending machine case 110 through the hot water container shelf 164 on which the hot water container 162 is mounted. It is detachably mounted on the material container shelf 150.

The driving means 140 is installed at the rear end of the material container shelf 150 facing the connection part 132. The drive means 140 is composed of a motor 142, a reduction gear 144 and an output shaft 146 for transmitting the rotational power decelerated in the reduction gear 144 to the ejector 130 through the connecting portion 132.

A mixer 170 is installed under the material container 120, and the mixer 170 is connected to the water supply valve 166 through a hose 172.

In the vending machine 100 as shown in Figure 1, if you want to refill the material container 120, slightly lift the front of the material container 120 so that the front bottom is released from the material container shelf 150 Pull the material container 120 forward to the rear bottom of the material container 120 to be separated from the material container shelf 150. In this process, the connecting portion 132 is also separated from the output shaft 146. Then, the material container 120 is lifted out of the case 110 to replenish the material, and then the material container 120 should be mounted on the material container shelf 150 in the reverse process of the separation.

It is very difficult to mount the heavy material container 120 filled with material back to the material container shelf 150. If the pin, gear, key, or key groove installed in the connecting portion 132 does not exactly match the groove, gear, key groove, or key at the end of the output shaft 146 during the mounting process of the material container 120, the output shaft 146 is connected to the connecting portion. Since it can not be coupled to the 132, while holding the connection portion 132 or the output shaft 146 of the screw 130 by hand, the work should be done. Since the output shaft 146 and the connecting portion 132 are behind the material container, there is a difficulty that the operator must mount the material container 120 to the material container shelf 150 depending on the sense.

In addition, when the door installed in the vending machine case 110 is opened to further supply raw materials, the hot water tank 162 may be exposed to lose heat.
