The present invention relates to an apparatus for supplying cold purified cold water by means of a freezer.

Conventional small vending machines generally perform a function of providing a coffee-based hot beverage in which coffee powder, prim powder and sugar powder are mixed with hot water, and a tea-based hot beverage in which dry powder is mixed with hot water. The small vending machine is made up of only what is necessary to provide a drink because the space inside is not large. Therefore, it is difficult to include other devices than parts for providing hot drinks.

In cold weather it is common to drink hot drinks, while in hot weather there is a greater need for cold drinks than hot drinks, and thus the need for conventional small vending machines that provide only hot drinks is reduced. There is a problem of being an unnecessary device. In order to solve this problem, there is a demand for a vending machine that can provide not only hot drinks but also cold drinks.

In order to provide the cold drink, a refrigeration system that first makes the water supply low temperature is essential. The refrigeration system is a compressor for compressing the refrigerant into a gas state of high temperature and high pressure, a condenser for cooling the refrigerant passing through the compressor to make a mixture of medium and high pressure gas and liquid, and expands the refrigerant passing through the condenser An expansion valve for low temperature and low pressure, and an evaporator for absorbing heat to sublimate the refrigerant. Therefore, if the refrigeration system is configured inside the vending machine, the size of the vending machine increases.

As a prior art for a vending machine equipped with a cooling device as described above, Korean Patent Laid-Open Publication No. 2003-0078234 ("Coffee Vending Machine") and Korean Registered Utility Model No. 0225719 ("Cold Drink Vending Machine Cold Water Supply Device"). ).

The "coffee vending machine" is to solve the disadvantage of the conventional vending machine that provides a cold drink by mixing the ice cube prepared by using the cooling device to the hot beverage, the raw material and hot water using the slush ice maker and the cooling means After converting the hot beverage produced by mixing the slush and stored at sub-zero temperatures, when the user selects the cold beverage, it is characterized in that to provide a beverage containing the slush. The "coffee vending machine" has an advantage that the slush consisting of smaller ice grains than ice cubes can be coldly drinked by the user as soon as the melting speed is faster than the ice cubes.

However, since the "coffee vending machine" includes a cooling means and a slush ice machine for converting the hot beverage into slush and storing the slush at subzero temperatures, the vending machine has a volume occupied by the cooling means and the slush ice maker. Since the size is increased, in the case of a small vending machine with no space in the inner space, the cold beverage cannot be produced by applying the above method. In addition, due to the additional necessity of the equipment to convert to the slush has a disadvantage that the economical efficiency is reduced due to the increase in device manufacturing cost.
