Water heater and control method thereof

Abstract

The invention provides a water heater and a control method thereof, an electromagnetic scale inhibition device is arranged on a water inlet pipeline of the water heater, and the control method comprises the steps that the water inlet hardness and the water inlet temperature of the water heater are obtained; determining the operation frequency of the electromagnetic scale inhibition device according to the inlet water hardness; adjusting the operation frequency of the electromagnetic scale inhibition device according to the water inlet temperature to obtain a corrected frequency value; and driving the electromagnetic scale inhibition device to output an electromagnetic signal according to the correction frequency value. The water heater can automatically output a proper electromagnetic signal according to the water inlet hardness of the water heater, so that scale generated by the water heater is reduced or avoided, and the working performance of the water heater is improved.

Description

technical field [0001] The invention relates to water heater technology, in particular to a water heater and a control method thereof. Background technique [0002] A water heater is a device that heats cold water to make hot water. However, since the water often contains impurities, scale will be generated when the water flows through the water heater, which will cause blockage of the water heater and reduce the working performance of the water heater. [0003] In the prior art, some water heaters lack anti-scaling devices, and can only rely on the user to manually remove the scale after the scale is generated. The user needs to disassemble the water heater and clean the scaled parts. The operation is complicated, and the disassembly process is likely to cause damage to the water heater, and the user experience is poor. . [0004] Therefore, how to reduce or avoid water heater scale generation has become a technical problem to be solved urgently by those skilled in the ar...
