ELECTRIC BOILER WITH WATER LEVEL ADJUSTING FUNCTION

摘要

The present invention takes into consideration that it expands when heating a large amount of heating water stored in the heat storage tank in the electric boiler that is heating by using the power supplied in the late-night time (electricity supplied from 22:00 to 08:00 the next day) as energy The built-in water level controller is installed in the area to be expanded to achieve the water level control with a simple structure, while preventing the impact and corrosion caused by the water level controller being exposed to the outside, and the bubbles scattered in the large amount of hot water stored for the heat storage The present invention relates to an electric boiler having a water level control function that prevents the boiler's heat storage tank from corroding and dissolving by dissolved oxygen and carbon dioxide and increasing the pH concentration. It is installed and discharged by mixing the bubble and the expansion water through the expansion water discharge pipe, the bubble is well 4% of the internal storage tank capacity of the upper heat storage tank 20 of the heat storage tank 20 to solve the problem of corroding the pipe by not discharging the dissolved oxygen and carbon dioxide due to the shortcomings or increasing the settling and pH values to shorten the service life of the boiler. The water level controller 40 is disposed at a predetermined position to form a water supply and water level control, and a bubble discharge pipe 30 is connected to the top of the heat storage tank 20 to suppress the discharge of vaporized water vapor when the heating water is heated, and discharge only the bubbles. ).
