Such a foodservice room is highly concerned about infectious diseases such as viruses and germs, so it is necessary to maintain thorough hygiene and environment.

Accordingly, an air purifier for sterilizing and purifying indoor air is provided in the group feeding room.

On the other hand, a drinking water supply device for supplying a large amount of drinking water is essentially installed in the group feeding room.

However, since a general drinking water supply device is provided with only drinking water by purifying raw water, it does not have a function of purifying the air, and thus it must be installed together with a separate air purifier, so there is a restriction in installation space and an economical burden is increased.

For example, in the case of a 'large water volume water purifier with a large water supply capacity' proposed in Korean Utility Model Registration No. 20-0419631 of the Republic of Korea and a 'large water capacity water purifier with a large capacity for a group water supply' proposed in Korean Patent Registration No. 10-0937954, And it is a technology to cool the drinking water by the instant cooler, but it does not have the function of purifying the air.

On the other hand, as a prior art of the air purifier, there is a 'air purifier having a photocatalytic filter module' proposed in Korean Patent Registration No. 10-0946106.

However, the air cleaner of the prior art is a constitution in which contaminated indoor air is sucked into the inside of the case, sterilized and purified, and discharged, and the cleaning agent such as anion or cation is discharged into the contaminated indoor space, There is a disadvantage in that it is insufficient in air purification since it does not have a purification structure.

Titanium dioxide (TiO ₂ ), also known as titanium dioxide or titanium dioxide, is an environmentally friendly material that has good acid resistance and alkali resistance and is harmless to the human body and converts various pollutants into harmless substances. Such titanium dioxide has a characteristic of being hydrophilic.

Specifically, when the titanium dioxide photocatalyst is an n-type semiconductor, when an ultraviolet ray (400 nm) is received, an electron and an electron hole are formed to produce hydroxyalcic acid (-OH) and superoxide having strong oxidizing power. Hydroxy radicals and superoxide decompose organic compounds into water and carbon dioxide.

In this way, pollutants in the air are oxidized and decomposed into harmless water and carbon dioxide, and the organic compounds, which are contaminants in the water, are decomposed into water and carbon dioxide. Since bacteria are also organic compounds, they are oxidized and decomposed by the strong oxidizing action of the photocatalyst and sterilized.

In addition, when light is irradiated, titanium dioxide reacts with one of the two oxygen atoms constituting H ₂ O in the air to generate a hydrophilic substance, and thus has a stain resistance to prevent adhesion of contaminants to the surface, (SELF-CLEANING) that allows the attached contaminants to be easily cleaned by water
