The present invention relates to a device for automatically disinfecting and cleaning a cold / hot water machine for drinking water, and more particularly, to remnants stuck to the inner wall of a water tank of a cold / hot water machine for drinking water and a cold / hot water valve pipe, for example, general bacteria and E. coli or other residues. The present invention relates to a cold and hot water automatic disinfection and cleaning device for disinfecting and cleaning harmful substances.

At present, water quality is contaminated even though various systems are being implemented to protect the water quality. Such water pollution will adversely affect not only the ecosystem of animals and plants, but also drinking water, which is the basic means of survival. The government is doing its best to strictly manage and prevent water pollution through various institutional systems such as designation of water quality protection area.

However, drinking water is exposed to many pollutants, not only from water sources, but also from tap water pipes to each household.

In other words, the drinking water may be contaminated due to corrosion of the water pipe or dirty water storage tank of the rooftop, thereby acting as an unstable factor for drinking drinking water in peace.

As a result, drinking water, such as purified mineral water or weak water, has been disseminated to remove various harmful components to drink drinking water with confidence, and its use is for drinking water to cool and heat drinking water to be selectively used according to season or purpose. Some people use cold and hot water together.

The cold / hot water machine is formed with a water tank having a predetermined space in the upper plane thereof, and is designed to mount drinking water in a water tank through the cold and hot water valves by mounting the periphery of the bucket of drinking water upside down.

However, when the water tank is mounted in the water tank, since the water is filled in the water tank for a long time until all the water in the water tank is consumed, harmful substances such as microorganisms in the water accumulated in the water tank, such as general bacteria and E. coli or other residues, etc. This is generated and accumulates on the inner wall of the tank or on the inner wall of the pipe of the hot and cold water valve, so it is necessary to disinfect and clean the tank regularly.

The conventional method for disinfecting or cleaning a water tank of a drinking water cooler or hot water dispenser is to disinfect or wash water and wipe cleaning tools such as a brush, but it is difficult to disinfect and clean a narrow part such as a pipe of a cold / hot water valve.
