Abstract
The utility model provides an electrical boiler which supplies drinking water with constant quantity and belongs to the electrical boiler, the electrical boiler is provided with a boiler inner container, an electrical heating pipe, a water inlet, a water nozzle, a flow control valve and a vent hole, wherein the vent hole is positioned on the upper end of a water tank, the water inlet is positioned on the lower end of the water tank, the electrical heating pipe is positioned on the water tank which is above the water inlet, the water nozzle is positioned on the side wall of the boiler inner container, the flow control valve is connected with a water inlet, and a power supply is connected with the electrical heating pipe through a switch. After tap water enters the boiler inner container, the water passes through the descaling type electrical heating pipe, exchanges heat with the descaling type electrical heating pipe and is heated to the set temperature, since the surface of the descaling type electrical heating pipe does not form scale permanently, the descaling type electrical heating pipe always keeps the optimum heating exchange efficiency, and the heat which is provided by the electrical heating pipe is matched with the heat which is needed by the water quantity of a water tank. The utility model has the advantages that the electrical boiler supplies water to the boiler inner container with constant quantity, cold water is heated to the set temperature when passing through a heating area, which prevents the generation of 'yin and yang of water' and 'thousands of boiling water' and improves the quality of outlet water.
Description
Technical field
The utility model relates to a kind of electric water-boiling device, the electric water-boiling device that particularly a kind of constant supplies drinking water.
Background technology
At present, the electric water-boiling device that people use is installed electric heater in water tank, temperature controller is arranged, and temperature controller is controlled the heating of electric heater or do not heated, and when the water in the water tank was heated to the temperature that can drink, heater stopped heating.Commercially available all electrothermal water heaters are the modes that drinking hot water intermittently is provided, just the amount of institute's heat supply water is controlled by cistern water level, the heat that provides of electric heating tube with configuration is not complementary, this mainly is because when the heat of the heat that is produced behind the electric heating tube outer wrapping incrustation scale when no incrustation scale wraps up, flow to the heat that the required heat of water volume in water tank temperature rise provides greater than electric heating tube, therefore cause water in the water tank to export when too much, the water that electric heating tube can't boil in the water tank is " water ", export the water that electric heating tube boils in the water tank repeatedly when very few and be " thousand boiling water ", when people drank, the harm people's was healthy.
The utility model content
The purpose of this utility model is to provide a kind of: the electric water-boiling device that the constant that heat that electric heating tube provided and the water yield of water tank institute calorific requirement are complementary supplies drinking water.
The purpose of this utility model is achieved in that this electric water-boiling device has boiler inner bag, electric heating tube, water inlet, water nozzle, flow control valve and venthole, venthole is positioned at the upper end of water tank, water inlet is positioned at the lower end of water tank, electric heating tube is positioned on the water tank of water inlet top, water nozzle is positioned at the sidewall of boiler inner bag, flow control valve is connected with water inlet, and power supply is connected with electric heating tube by switch.
Described electric heating tube is a scale removal type electric heating tube, and scale removal type electric heating tube includes heating tube, stay-furring tool, force transmitters and driver, and stay-furring tool is socketed on the heating tube, and force transmitters one end is connected with stay-furring tool, and the other end is connected with driver.
Described flow control valve is a magnetic valve, and magnetic valve is connected with power supply by water level switch, and water level switch is positioned at the upper end of water tank; Perhaps be choke valve and the pressure-reducing valve that is connected in series.
Beneficial effect: owing to adopted such scheme, running water is subjected to flow control valve control to flow into the boiler inner bag through water inlet with certain flow, flow into boiler inner bag water by the scale removal type electrothermal tube from water inlet, and carry out exchange heat with the scale removal type electrothermal tube, and be heated to design temperature, because the permanent non-scaling in scale removal type electric heating tube surface, scale removal type electric heating tube always keeps the optimal heat exchange efficiency, when hot water arrives water level controller, provide the signal at stop flow control valve by water level controller, when water level is lower than water level controller, water level controller turn-on flow rate controller is intake to the boiler inner bag, heat that electric heating tube provided and the water yield of water tank institute calorific requirement are complementary, and have reached the purpose of this utility model.Advantage: this electric water boiler constant supplies water to the boiler inner bag, the heat coupling that water supply institute's calorific requirement and electric heating tube provide, when making cold water flow through the thermal treatment zone, promptly be heated to design temperature, thereby avoided the generation of " water ", " thousand boiling water ", improved effluent characteristics, control and simple in structure.
