Electric water heater with water purification function and water purification method

Abstract

The invention discloses an electric water heater with water purification function, which comprises a heating device with a water inlet pipe and a water outlet pipe, and also includes a water purification device arranged at the water inlet pipe. The main pipe and the side pipe, the side pipe is provided with a purification filter, and one end of the main pipe is connected with the side pipe through a waterway reversing valve, or the main pipe and the side pipe are respectively provided with a waterway switch. The water purification device has two water flow channels, one of which is provided with a purification filter, so that the bath water can be selectively purified, effectively purifying the water quality, delaying the formation of scale and ensuring the health and safety of the bath water. At the same time, it is more flexible, effectively prolonging the service life of the filter element and reducing the cost of water purification. At the same time, the water purification device of the electric water heater also has a backwash function, which further ensures the filtration efficiency and water flow of the filter element. The invention also provides a water quality purification method for the electric water heater.

Description

technical field [0001] The invention relates to the technical field of electric water heaters, in particular to an electric water heater with water purification function and a water purification method. Background technique [0002] Due to the continuous development of modern industry, environmental pollution is becoming more and more serious, and the quality of domestic water is getting worse and worse. Some electric water heaters use simple filter mesh filter devices to filter water to improve water quality, but existing electric water heater filter devices can only filter out larger particles of impurities in water, while calcium and magnesium ions in water, and dissolved in water Other harmful substances such as bleaching powder cannot be effectively filtered out, and the filtering effect is not ideal. Therefore, during the bathing process, residual chlorine and other harmful substances in the water will also cause damage to the human skin or cause allergies. Since the ...

Problems solved by technology

Some electric water heaters use simple filter mesh filter devices to filter water to improve water quality, but existing electric water heater filter devices can only filter out larger particles of impurities in water, while calcium and magnesium ions in water, and dissolved in water Other harmful substances such as bleaching powder cannot be effectively filtered out, and the filtering effect is not ideal. Therefore, during the bathing process, residual chlorine and other harmful substances in the water will also cause damage to the human skin or cause allergies.

Since the calcium and magnesium ions in the water cannot be filtered out, the consumption rate of the magnesium rods used for the anti-corrosion protection of the inner tank of the electric water heater cannot be delayed, and the calcium and magnesium ions are easily combined with the acid radical ions in the water to form difficult dissolved substances, and stick to the inner tank of the electric water heater to form scale, thus corroding the inner tank

In addition, the existing electric water heater filter device has a small water flow rate, which often cannot meet the water demand
