[0002] The electric water heater is an essential household appliance. It heats the water through the electric heating tube. However, the existing electric water heater will always be in the state of energization and heat preservation after heating the water. Due to the high power of the electric water heater, if it is always in the state It will not only reduce the service life of the electrical appliance itself, but also cause long-term power consumption, increase the cost of use, and there is a risk of leakage, which is not conducive to energy conservation and environmental protection

The invention discloses a PLC control intelligent power-off water heater which comprises a water storage liner; the water storage liner is of a cavity structure and is internally provided with an electric heating pipe, a temperature inductor and a liquid level inductor; and the temperature inductor and the liquid level inductor are connected with a PLC through wires respectively. The PLC control intelligent power-off water heater has the beneficial effects that by connecting the PLC with the temperature inductor in the water heater and matching use of a power switch, the water heater can be automatically powered off when a water temperature in the water heater reaches a set temperature, and the purposes of preventing electric leakage and saving electricity consumption are achieved; and byconnecting the PLC with the liquid level inductor in the water heater and matching use of an electromagnetic valve, automatic water addition is realized when a liquid level in the water heater is lower than the liquid level inductor, the purpose of saving water consumption is achieved, the water heater saves more energy and is more environmentally friendly, the working efficiency and the use safety are improved, and the use cost is lowered.
