Problems solved by technology

At present, the water heaters on the market generally do not take corresponding measures against the scaling of the inner barrel due to the hard water quality. Some products use an external magnesium rod as the anode and the inner barrel as the cathode to protect the inner barrel, but it is not popular.
The reason is that there are mainly the following problems, because magnesium is an active metal, and as an anode, it will be continuously corroded and needs to be replaced regularly, which is inconvenient; secondly, this method has no obvious effect on removing the scale on the inner wall of the water heater

Embodiment Construction

[0013] Such as figure 1 , figure 2 As shown, the main components of the adjustable cathodic protection water heater of the present invention are a water storage tank 1, an auxiliary anode 3 made of stainless steel, a polarity exchanger 4, an external power supply 5, a scale removal button or a remote control 6, and the water storage tank 1 is provided with a The sewage outlet, the auxiliary anode 3 is separated from the water storage tank 1 by an insulating sleeve, the positive pole of the external DC power supply 5 is connected to the auxiliary anode 3, and the negative pole is connected to the stainless steel inner barrel of the water storage tank 1. Provide electrons to the surface of the stainless steel inner barrel of the water heater, which greatly prevents the iron in the stainless steel of the inner barrel from turning into Fe 2+ form rust, on the other hand Ca in water 2+ , Mg 2+ It will also continue to gather on the stainless steel barrel wall as the cathode to ...

Abstract

The invention discloses an adjustable cathode protective water heater, comprising a water storage tank provided with a metal inner barrel which is provided with an auxiliary anode with an inertial material and is used as the cathode; the auxiliary anode and the metal inner barrel are electrically connected with an additional direct current power supply through a polarity conversion device; when the polarity conversion device is in normal state, the auxiliary anode is electrically connected with the anode of the additional direct current power supply; and the metal inner barrel is electrically the cathode of the additional direct current power supply. In the invention, an additional direct current power supply cathode protective device is utilized to soften the water quality to achieve the purpose of using water heathily, and protect the corrosion prevention to a stainless steel inner barrel; and meanwhile, through the exchanging of the polarity, the cathode protective device is converted into an electrolysis device, so as to achieve the requirement of automatically removing the water scales.

Description

technical field [0001] The invention relates to an external current cathodic protection type water heater with softened water quality, anti-scale and anti-corrosion stainless steel inner barrel. Background technique [0002] The water heater heats water from a low temperature to a higher temperature to meet the needs of people for hot water in life and production. At present, most water heaters on the market have not taken corresponding measures against scaling in the inner barrel due to hard water. Some products use external magnesium rods as anodes and inner barrels as cathodes to protect the inner barrels, but this is not popular. Its reason is that mainly there are following problems, because magnesium is an active metal, it will be corroded continuously as an anode, and it needs to be replaced regularly, which is inconvenient to replace; secondly, this method has no obvious effect on removing the scale on the inner barrel wall of the water heater.
