Description

Zero cold water device of water heater

Technical Field

The utility model relates to a water heater field, in particular to zero cold water device of water heater.

Background

At present, in the daily use process of the water heater, a part of cold water is inevitably discharged when water is discharged, and the cold water is generally discharged until hot water flows out, so that the normal use is not started. Particularly, when the water heater is used in winter, water in the whole hot water system pipeline is cold, and water in the water pipe is possibly frozen to influence the normal use of the water heater.

In addition, due to the use environment, tap water or outdoor water sources which are commonly used can generate scale deposition on the inner wall of the water channel pipeline of the gas water heater due to water quality difference. The deposition speed of the scale is accelerated when the water temperature exceeds 60 ℃. The more scale will accumulate with time. When people drink water containing scale, scale fragments enter the stomach and react with hydrochloric acid to release calcium and magnesium ions and carbon dioxide, wherein the calcium and magnesium ions and the carbon dioxide are necessary substances for forming calculus. The latter can be a source of flatulence and discomfort, and gastric ulcer patients may also be at risk of gastric perforation. When the scale is cemented, a large amount of heavy metal ions are attached to the scale, and the risk that the heavy metal ions are too much dissolved in drinking water is caused. The scale attached to the inner wall of the pipe endangers the safe and economical operation of the equipment. Because scale has poor thermal conductivity, heat transfer is hindered. The heat absorbed from the flame side is not well transferred to the water, and the cooling of the furnace tube is affected, so that the wall temperature rises, causing the furnace tube to bulge, causing tube explosion. Scale is poorly thermally conductive and can cause heat transfer from the heated surface to be degraded, thereby wasting fuel or electricity. The chemical analysis of the scale stored in a 5 pound thermos for 18 days by experts revealed that it contains various harmful heavy metal substances, cadmium 0.034 mg, lead 0.12 mg, iron 24 mg, arsenic 0.21 mg and mercury 0.44 mg. This indicates that even drinking water meeting sanitary standards, trace metal elements can be precipitated and accumulated in the water after being stored in the thermos bottle, thus endangering human health. The potential health hazard is even more serious if the drinking water does not meet the hygienic standards. Regular drinking can cause diseases of digestive, nervous, urinary, hematopoietic, circulatory systems and the like to cause aging, which is caused by the fact that the scale contains more harmful metal elements such as cadmium, mercury, arsenic, aluminum and the like. It is often necessary to remove scale for our health.
