Energy-saving heat exchange device of direct drinking water equipment

Abstract

The invention discloses an energy-saving heat exchange device of direct drinking water equipment. The direct drinking water equipment comprises a water tank, and a heating pipe is arranged in the water tank; the water tank is provided with a boiling water outlet; the energy-saving heat exchange device is characterized by comprising a heat exchanger; the heat exchanger is provided with a hot water inlet, a warm water outlet, a cold water inlet and a preheating outlet; the hot water inlet is connected with the boiling water outlet of the water tank; the warm water outlet of the heat exchanger is connected with a warm water outlet nozzle of the direct drinking water equipment; the cold water inlet of the heat exchanger is connected with a water inlet of the direct drinking water equipment; the preheating outlet of the heat exchanger is connected with a preheating water inlet of the water tank; hot water flowing out of the boiling water outlet of the water tank flows out of the warm water outlet nozzle after being subjected to heat exchange by the heat exchanger; and cold water flowing into a water inlet of the water tank flows into the preheating water inlet of the water tank after being subjected to heat exchange by the heat exchanger. The device is directly applied to the newly produced direct drinking water equipment provided with the open water tank, is rapid, sanitary and energy-saving and solves the problem of drinking water in campuses, and original direct drinking water equipment can be transformed according to the energy-saving heat exchange device provided by the invention.

Description

technical field [0001] The invention relates to the technical field of water treatment equipment, in particular to an energy-saving heat exchange device for direct drinking water equipment, in particular capable of exchanging heat and providing drinking warm water in the direct drinking water equipment of an open water tank. Background technique [0002] Open water tank direct drinking water equipment can usually provide boiled water and cold water. In order to meet the drinking water needs of students, campus direct drinking water equipment usually requires boiling water and drinking warm water at about 40 °C. [0003] One, the method that the known open water tank direct drinking water equipment provides drinking warm water is: [0004] 1) Mix cold and hot water to reach drinking temperature warm water. Since there is almost no residual chlorine in the purified water, at room temperature (environmental temperature), cold water is prone to breed bacteria, and the mixed dri...

AI Technical Summary

Problems solved by technology

[0010] According to the above three types of open water tank direct drinking water equipment, there are a large number of existing and used in the campus, continue to use, can not guarantee the sanitation and safety of drinking water or the waste of energy is serious, and the mandatory scrapping will cause great economic losses to the school and the country.
