Description

Drinking fountain

This creation is about water dispensers, especially an energy-saving water dispenser that packs drinking water.

Drinking fountains are often used in public places, and the water dispensers that are seen have a type of water supply connected to the tap water pipe and a type that uses packaged drinking water to supply water. Since the water supply for packaging drinking water is not pressurized, the construction of the water dispenser generally has a vertically arranged cold water bladder and a hot water bladder. Generally, the cold water is placed above the hot water bladder, and the water bottle is placed above the water dispenser to inject the drinking water into the cold water bladder by gravity. The cold water bladder and the hot water bladder are connected by a vertically arranged straight pipe, and the normal temperature water in the cold water bladder can flow into the hot water bladder through the straight pipe, and the hot water bladder is provided with a heating device to heat the water therein. . The cold water bladder and the hot water bladder are respectively provided with valves, so that hot water or room temperature water can be separately taken. Among them, cold water can also be equipped with a refrigeration device to generate cold water according to demand.

The disadvantage of the prior structure described above is that when the drinking water in the hot water bladder is heated and boiled, the pressure in the hot water bladder rises, and the high temperature drinking water and steam recirculate upward along the straight pipe, thereby causing high temperature drinking water or steam and Cold water heat exchange in cold water bladder. The cold water temperature is too high and the hot water temperature is too low, so the heating device and the cooling device need to be frequently started to maintain the required water temperature of the cold and hot water, thus causing unnecessary power waste.

In view of this, the creator has made great efforts to solve the above problems by focusing on the above-mentioned prior art, and has devoted himself to the application of the theory, that is, the goal of the creator's improvement.

This creation provides an energy-saving water dispenser for packaging drinking water.

When the drinking water in the hot water tank 300 is heated and boiled, the pressure in the hot water tank 300 rises, and the high temperature drinking water and vapor return upward along the lower end 420 of the coil 400, but the high temperature drinking water and vapor are trapped by the coil 400. The middle section 430 is limited and horizontally coiled, so it cannot be returned to the upper end 410 of the coil 400. Thereby, high-temperature drinking water or steam can be prevented from passing through the cold water zone 203 of the cold water tank 200, so that heat exchange between cold and hot water can be avoided, so that the starting frequency of the heating assembly 320 and the compressor 232 can be reduced, and the energy consumption of the water dispenser can be reduced.
