BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a cold / hot water purifier, and more particularly, to a power saving cold / hot water generator having a waste heat recovering function.

In recent years, rapid economic growth and improved living standards have led to a significant increase in energy consumption, and there has been a growing interest in energy saving and recycling methods for recovering waste heat.

However, in the field of cold / warm water purifiers, rather, devices that emit heat cause degradation of the performance of the cold / hot water purifier. To solve the problem, some techniques have been proposed and the waste heat is being abandoned as it is.

2. Description of the Related Art Generally, a cooling system of a cold / warm water purifier includes a compressor for compressing refrigerant in a gaseous state, a condenser for condensing high heat contained in high-temperature refrigerant passing through the compressor to a refrigerant, And a cooling coil wound around an outer wall of the cooling tank to cool the cooling tank.

That is, in the conventional cold / warm water purifier, the heat of the compressor and the heat of the heat radiating plate are gathered in the compact internal space of the body, excessively raising the internal temperature of the cold / hot water purifier to lower the heat insulating performance of the cold water tank, Frequent failures of the compressors are caused and the performance of the cold / hot water purifier is lowered during the summer season.

Accordingly, in order to solve such a problem, the cold / warm water purifier needs to have a separate cooling device for lowering the internal temperature, so that additional power consumption occurs.

Meanwhile, in the conventional water purifiers, the tap water to be supplied is first purified by the water filter, the purified water is stored in the cold water tank and the hot water tank, and a separate pipe is connected from each tank to the coke, In the case of the water purifier according to the above-described structure, when the water purifier is not used, the water staying in the pipe connecting each tank and the cork is deteriorated due to the structure as described above.
