Water heater

Abstract

The invention discloses a water heater. The water heater comprises an inner container, a water inlet pipe, a water outlet pipe and a heater body. The water heater is characterized in that the water heater further comprises an electromagnetic device separated from the heater body; the electromagnetic device comprises an induction coil and a circuit control unit, and the circuit control unit is connected with two leads of the induction coil to form a closed loop; the induction coil is arranged in the inner container, so that both an internal magnetic field and an outer magnetic field of the induction coil are fully used to magnetize water in the inner container; one electromagnetic device can be arranged, the induction coil can be wound on the pipe section, located in the inner container, ofthe water inlet pipe or is wound on the pipe section, located in the inner container, of the water outlet pipe; or two electromagnetic devices are arranged, and the corresponding induction coils areseparately wound on the water inlet pipe and the water outlet pipe located in the inner container. According to the water heater, it can be ensured that water in the inner container is fully magnetized, so that the probability of scale formation is lowered, and meanwhile, magnetized water used for bathing can be provided for users.

Description

technical field [0001] The invention relates to the field of water heaters. Background technique [0002] An electric water heater mainly consists of an inner tank, a heating pipe, an inlet and outlet pipe, and a control system. A certain amount of tap water is stored in the inner tank, and municipal tap water is generally taken from natural water bodies, which inevitably contains a certain concentration of calcium, magnesium, carbonate, Scaling ions such as bicarbonate. During the working process of the heating tube, the scale-forming ions in the tap water will be enriched on the surface of the heater to form scale, which will be deposited on the surface of the heating tube, affecting the water quality of the inner tank, and will also reduce the utilization rate of electric energy and increase energy consumption. In the repeated heating environment, it may disperse into small particles, and then block the water inlet and outlet pipes, causing safety hazards. Contents of ...

Problems solved by technology

[0003] The main purpose of the present invention is to propose a water heater, which aims to solve the technical problem that the surface of the heater is easy to condense when the water heater is heated, and the generated scale disperses and blocks the water passage or pollutes the water body of the inner tank.
