Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial field of application) The present invention is an automatic cup-type beverage that mixes ice into an infused beverage by supplying ice into a cup that is carried onto a bend stage. The present invention relates to an ice supply device for a vending machine.

(Prior Art) A cup-type beverage vending machine that sells ice-containing beverages by mixing the produced beverage with ice, which is convenient for storing small lumps of ice in a short time, for example, Jikho Sho 60-13025. It is equipped with an auger type ice machine as shown in. And the ice made by this ice making machine is stored in the ice storage tank which is formed continuously above it, and a predetermined amount of ice is produced from the ice storage tank through the ice chute according to the command of the sales supply signal. It is designed to be discharged and supplied into the cup on the bend stage.

On the other hand, the ice chute part is composed of a cover member provided to cover the carry-out port of the ice storage tank and a hose-shaped duct connected to the lower end of the opening of the cover member in a continuous manner. Is taken into consideration so that no one can enter.

(Issues to be solved by the invention) However, the ice made by the auger type ice making machine uses the water supplied from the tap water, and the ice that grows in a thin film on the inner wall of the cooling cylinder is sequentially attached. Since it is forcedly compressed while peeling off, it is made into small pieces of ice in a short time, so
Floating materials such as calckey contained in tap water are mixed as they are to make ice. Therefore, when the ice is supplied to the cup, while the ice passes through the ice chute, the floating substances are melted from the ice together with the water, and are attached to the inner surface of the ice chute to be gradually accumulated.

When the above-mentioned suspended matter adheres to and accumulates on the inner surface of the ice chute, there is also nutrition of various bacteria as well as dust, and the inner surface of the chute is always wet by the water that melts from the ice as it passes through the Since the temperature inside the vending machine becomes a temperature that is suitable for the propagation of various bacteria, and the conditions are easily adjusted, in order to keep this part hygienic at all times, it is necessary to simply block the dust entering from the outside. Although it is still incomplete in preventing the propagation of miscellaneous bacteria, from the viewpoint of hygiene, it is also an important issue to remove the suspended matter attached by the above by periodic cleaning.
