Multifunctional water heater

Abstract

The invention provides a multifunctional water heater. The water heater comprises a water tank, wherein a heating device is arranged in the water tank, the water tank is connected with a water outletpipe and a sewage discharge pipe, a heat exchange water pipe is further arranged in the water tank, a water outlet end of the heat exchange water pipe communicates with the water outlet pipe, the water tank is provided with a cold water inlet pipe and a water tank water inlet pipe, the cold water inlet pipe communicates with a water inlet end of the heat exchange water pipe, and the water tank water inlet pipe communicates with an inner cavity of the water tank. According to the water heater, water in the water tank is heated to exchange heat with water in the heat exchange water pipe to achieve heat-up, the water in the water tank is heated through the heating device to enable metal ions in the water in the water tank to carry out chemical reaction, on the premise that the water tank is not supplemented with water and the water in the water tank is recycled, the water in the water tank is gradually changed into pure water, after being used for a long time, water scale is not regenerated to cover on the heating device, so that the heat of the heating device is transferred out faster, and the heating speed of the water heater is increased.

Description

technical field [0001] The invention relates to the field of thermal storage water heaters, in particular to a multifunctional water heater. Background technique [0002] The storage water heater structure currently on the market includes a water tank, a heating device is installed in the water tank, and a water inlet pipe and a water outlet pipe are arranged on the water tank. After the cold water in the water tank is heated to a certain temperature by the heating device, the heat is discharged through the water outlet pipe.

[0002] The storage water heater structure currently on the market includes a water tank, a heating device is installed in the water tank, and a water inlet pipe and a water outlet pipe are arranged on the water tank. After the cold water in the water tank is heated to a certain temperature by the heating device, the heat is discharged through the water outlet pipe. Water, during the heating process, because there are many metal ions in the cold water, such as calcium ions or magnesium ions, etc., when the heating device heats up, a chemical reaction will occur, and the calcium ions will be converted into scale substances such as calcium carbonate, which will cover the On the outer surface of the heating device, when the cold water in the water tank is continuously replenished, new metal ions will continue to undergo chemical reactions when the heating device heats up. After long-term use, the outer surface of the heating device will be covered with thicker scale, causing the heating device to The speed of heat transfer to the outside slows down, which weakens the heating efficiency of the water heater and increases energy consumption. Severe scale covering the surface of the heating device will prevent the heat from being transferred out, resulting in the surface temperature of the heating device being too high, bursting, and causing leakage accidents.
