Anti-corrosion method for inner container of water heater

Abstract

The invention discloses an anti-corrosion method for an inner container of a water heater. A solar water heater is provided with a thermoelectric generator and a Fresnel lens; and the anti-corrosion method comprises the steps that the Fresnel lens is utilized to irradiate the hot end face of the thermoelectric generator so that the thermoelectric generator can generate electric energy by utilizingthe temperature difference, and the electric energy generated by the thermoelectric generator acts on the inner container of a heat pump water heater to form current so that current anti-corrosion protection can be carried out. According to the anti-corrosion method for the inner container of the water heater, the Fresnel lens is utilized to irradiate the thermoelectric generator to generate electricity to provide current for an inner container of a water tank so that corrosion prevention can be carried out, and therefore the bathing experience is improved, the use cost is reduced, and the user experience is effectively improved.

Description

technical field [0001] The invention relates to water heater anticorrosion technology, in particular to a water heater inner tank anticorrosion method. Background technique [0002] At present, water heaters are common household appliances in people's daily life. Water heaters are divided into: electric water heaters, heat pump water heaters and solar water heaters. Solar water heaters usually include heat collectors and water tanks. The heat collector uses solar energy to heat the water inside. The hot water formed by the heating of the heater is stored in the water tank. However, after the water tank is used for a long time, the water will corrode the water tank. The conventional anti-corrosion method of the water tank usually uses an enamel liner and uses it together with magnesium rods. However, during use, on the one hand, the reaction of magnesium rods into magnesium ions will increase the hardness of the water and reduce the bathing experience. On the other hand, mag...

Problems solved by technology

However, after the water tank is used for a long time, the water will corrode the water tank. The conventional anti-corrosion method of the water tank usually uses an enamel liner and uses it together with magnesium rods.

However, during use, on the one hand, the reaction of magnesium rods into magnesium ions will increase the hardness of the water and reduce the bathing experience. On the other hand, magnesium rods are consumables and need to be replaced regularly, which increases the cost of use and leads to poor user experience.
