Gas water heater capable of intelligently purifying water and discharging sewage

Abstract

The invention discloses a gas water heater capable of intelligently purifying water and discharging sewage. The gas water heater comprises a gas water heater body, and a water inlet pipeline and a water outlet pipeline are arranged in the gas water heater body; and the water inlet pipeline and the water outlet pipeline are connected with a heat exchanger. The gas water heater is characterized in that a preposed filter device and a flow sensor are arranged at the water inlet pipeline section of the gas water heater body; the preposed filter device is connected with a water inlet and a water outlet; a filter screen is arranged between the water inlet and the water outlet of the preposed filter device; the pipeline in front of the filter screen is further connected with a blowdown pipe; a ball valve switch is arranged on the blowdown pipe; two modes are achieved through the preposed filter device; when the switch is closed, a waterway is open, the gas water heater is in the water purification mode; and when the switch is opened, the waterway is closed, and the gas water heater is in the blowdown mode. According to the gas water heater, water can be purified, impurities in tap water are effectively removed, bacterium breeding is inhibited, filtered impurities in the filter can be flushed, the gas water heater is repeatedly utilized, comfort during bathing is improved, and a safe, healthy and comfortable bathing environment is created.

Description

technical field [0001] The invention relates to the technical field of gas instant water heaters, in particular to the water purification and sewage discharge technology of gas instant water heaters. Background technique [0002] Because municipal tap water is transported through long pipelines and treated with chlorine gas in waterworks, the water will contain rust, residual chlorine and other impurities that affect water quality. In some areas, the water hardness is relatively high, especially in the north. Hard water not only affects the comfort and health of users when bathing, but also causes pipeline blockage. At present, there are few gas water heaters with water quality treatment on the market. Even if there are, industrial adsorbents are used for single water quality treatment. Limited by the amount of adsorbents, sustainability cannot be achieved. It may even cause clogging due to the adsorption of a large amount of impurities by the adsorbent, reducing the water ...

Hard water not only affects the comfort and health of users when bathing, but also causes pipeline blockage

At present, there are few gas water heaters with water quality treatment on the market. Even if there are, industrial adsorbents are used for single water quality treatment. Limited by the amount of adsorbents, sustainability cannot be achieved.

It may even cause clogging due to the adsorption of a large amount of impurities by the adsorbent, reducing the water flow, which is not conducive to the comfort of the user for bathing
