Multifunctional gas water heater

Abstract

The invention discloses a multifunctional gas water heater. The gas water heater comprises a water heater body, a heat exchanger mounted on the water heater body as well as a water inlet pipe and a water outlet pipe which are connected with the heat exchanger. The gas water heater is characterized in that a three-way valve is connected onto the water inlet pipe and divides the water inlet pipe into two branches, a water pump is arranged on one branch of the water inlet pipe, a water purifying and softening device is arranged on the other branch of the water inlet pipe, and ion exchange resin and activated carbon are arranged in the water purifying and softening device. Compared with the prior art, the gas water heater has the advantages that the water purifying and softening device is arranged, water scale production is effectively inhibited, and pipe blockage, especially blockage of a shower head, is avoided; meanwhile, the ion exchange resin and the activated carbon are arranged in the water purifying and softening device, hard water becomes soft water after passing through the ion exchange resin, the soft water contains little calcium magnesium salt and is smooth, and the bathing effect is better; the activated carbon purifies the water effectively, removes impurities and dirt, inhibits bacterium breeding and creates a safe, healthy and comfortable bathing environment.

Description

technical field [0001] The invention relates to the technical field of fluid heaters, in particular to a multifunctional gas water heater. Background technique [0002] Gas water heater is a very commonly used household water supply device. 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 blockage of pipelines, especially the blockage of showers, which greatly affects the use effect. There are few gas water heaters with water quality treatment on the market now, and even if there is, there is only a single function of water quality purification, or sterilization, or softening, resulting in a waste of resources.

Problems solved by technology

Although this utility model can solve the scale problem to a certain extent, it relies on the heat preservation water tank and has a single water mode; and the three-stage filter itself has a complex structure and is not easy to maintain
