Power saving device of water heater

Abstract

The invention discloses a power saving device of a water heater. The power saving device of the water heater comprises a controller, a power saving device body and the water heater. The controller is located below the power saving device body and electrically connected with the power saving device body. The controller is internally provided with a variable-frequency input unit, a relay and a variable-frequency output unit which are electrically connected. More than one external power line is arranged on the variable-frequency input unit. The water heater is located on the right side of the controller and comprises a cold water inlet, a heating ring and a hot water outlet, wherein the cold water inlet is formed in the lower portion of the water heater; a ceramic tube is arranged outside the heating ring; an electromagnetic coil is arranged outside the ceramic tube; the hot water outlet is located in the upper portion of the water heater. The power saving device of the water heater has the advantages that water is heated rapidly, power consumption is reduced and electric leakage is avoided.

Description

technical field [0001] The invention relates to an electricity-saving device for a water heater. Background technique [0002] In recent years, the gap in electricity load has become larger and larger, and coal resources have also become more and more scarce, especially during the peak period of residential electricity consumption, and the water in solar water heaters that are now widely used cannot be used for drinking and cooking. Yes, this is because on the one hand, although the water entering the water heater is clean tap water, the metal used to make the water heater pipes often contains some harmful poisons exceeding the standard, such as lead, manganese, arsenic, etc., which are harmful to the body when used for cooking for a long time. Harmful. On the other hand, the temperature of the water heated by solar water heaters is generally between 40 and 70 degrees. It is suitable for the large-scale reproduction of germs and viruses. In addition, the water in solar energ...

[0002] In recent years, the gap in electricity load has become larger and larger, and coal resources have become more and more scarce, especially during the peak period of residential electricity consumption, and the water in solar water heaters that are now widely used cannot be used for drinking and cooking. Yes, this is because on the one hand, although the water entering the water heater is clean tap water, the metal used to make the water heater pipes often contains some harmful poisons exceeding the standard, such as lead, manganese, arsenic, etc., which are harmful to the body when used for cooking for a long time. Harmful. On the other hand, the temperature of the water heated by solar water heaters is generally between 40 degrees and 70 degrees. It is suitable for the proliferation of germs and viruses. In addition, the water in solar energy is often overnight. Due to the long-term retention and the influence of temperature, the water in the water The chlorine that plays a disinfection role will gradually decrease or even disappear, and drinking it is harmful to the body
