Abstract
The invention discloses a fast type electric water heater. In the electric water heater, hollow electric heating tube pass through water tanks vertically, and seal rings are sealed between the hollow electric heating tubes and the water tanks; three groups of hollow electric heating tubes and water tanks are connected in series, and U-shaped pipes are connected between the hollow electric heating tubes and the water tanks; a water inlet pipe is connected with the upper opening of the first hollow electric heating tube; a water heat pipe is connected with the upper joint of the last water tank; an isolation mesh is arranged on each joint; a cleaning ball is arranged in each hollow electric heating tube; the cleaning ball is also arranged in each water tank; a water mixing valve is connected with a cool water pipe, the heat water pipe and a water outlet pipe; when the electric water heater is used, tap water enters the hollow electric heating tubes through the water inlet pipe to drive the cleaning balls to move downwards and wash scale on the inner surface of the hollow electric heating tubes, and the water is heated; and the water enters the water tanks through the U-shape pipes, under block of banes, the water drives the cleaning balls to rotate upwards around the outer surface of the hollow electric heating tubes and wash scale, and the water is heated once again. The hot water and tap water are mixed for people use.
Description
Technical field:
The present invention relates to a kind of quick-heating type electric water heater.
Background technology
The quick-heating type electric water heater that sell in market all be the water that uses in the solid electric heating tube heating water tank of metal, and the power of electric heating tube is all very large.We know, the metal electric heat-generating pipe when the energising heating water, calcium bicarbonate be deposited on metal electric heat-generating pipe surface after the iron hydroxide decomposes becomes calcium carbonate and iron hydroxide, form dirt.The power of metal electric heat-generating pipe is larger, surface area is less, the water that flows through metal electric heat-generating pipe surface less, slower, just faster, more at the dirt of metal electric heat-generating pipe Surface Creation; Thereby affect the metal electric heat-generating pipe heat transferred water, and cause the overheated and oxidation of metal electric heat-generating pipe surface corrosion and inner resistance wire.Shortened the service life of metal electric heat-generating pipe.The metal electric heat-generating pipe of some quick-heating type electric water heater be removable, can wash; But during dismounting, tear electric wire open and tear screw open.The layman can not remove to tear open the metal electric heat-generating pipe.
Summary of the invention:
The present invention can eliminate the defective of existing quick-heating type electric water heater.
Quick-heating type electric water heater of the present invention is comprised of shell, electric heating tube, water tank, water inlet pipe, cold water pipe, hot-water line, mixed water valve, outlet pipe, heating selector switch, display screen and electric control system.The handle of display screen and heating selector switch is exposed at outer casing frontispiece.Running water pipe divides two-way, the one tunnel taps into water pipe, another road connects cold water pipe.The delivery port of hot-water line is connected on the hot water mouth of mixed water valve, and the delivery port of cold water pipe is connected on the cold water outlet of mixed water valve, and outlet pipe is connected on the delivery port of mixed water valve.Described electric heating tube is the hollow electric heating tube of at least one linear pattern, and a hollow electric heating tube forms one group with a water tank, organizes the use of connecting more.The bottom cover of hollow electric heating tube has lower seal, and hollow electric heating tube is upward through water tank from water tank bottom; Described lower seal is pressed on the water tank bottom surface by the flange on the hollow electric heating tube.Upper sealing ring is enclosed within the top of hollow electric heating tube, is pressed in by trim ring on the end face of water tank.Be connected with U-shaped pipe between the mouth of pipe of hollow electric heating tube and the mouth of pipe of water tank, the upper orifice of first hollow electric heating tube is connected with the delivery port of water inlet pipe, and the upper orifice of last water tank is connected with the water inlet of hot-water line.Except the mixed water valve, separation net is equipped with in the junction of each mouth of pipe; There is a circle rubber at the edge of separation net, is used for sealed interface.Upper cleaning bead is arranged in the hollow electric heating tube, and the buoyancy of upper cleaning bead in water is greater than gravity.Lower cleaning bead is arranged in the water tank, and the buoyancy of lower cleaning bead in water is less than gravity, and the surface of upper cleaning bead and lower cleaning bead is all very coarse.The mesh of separation net is less than the straight warp of upper cleaning bead and lower cleaning bead, and separation net is isolated in upper cleaning bead in the hollow electric heating tube, lower cleaning bead is isolated in the water tank.At the inwall away from the water tank of hollow electric heating tube at least a slice vane is housed, vane make the current that enter water tank with lower cleaning bead around hollow electric heating tube rotation on.
Adopt the quick-heating type electric water heater of this structure, first electric heater is filled with water.Rotate and select the handle of heater switch to select heating power, to the water in the hollow electric heating tube and the heat of the water price in the water tank.Adjust the position of mixed water valve handle, allow the one tunnel upper cleaning bead that in water inlet pipe enters hollow electric heating tube, promotes in the hollow electric heating tube of running water, minute speed, successively toward descending; And clash into hollow electric heating tube inner surface, rub off the dirt of hollow electric heating tube inner surface.These current flow into water tank through U-shaped pipe and clean bead under drives under the stopping of vane, minute successively, speed around the outer surface rotation of hollow electric heating tube on; Clash into the outer surface of hollow electric heating tube, rub off the dirt of hollow electric heating tube outer surface.Current enter next hollow electric heating tube and water tank is heated one by one like this, enter at last hot-water line; Enter mixed water valve from hot-water line again, mix rear from the outlet pipe outflow, for people's bathing with the running water that enters mixed water valve from cold water pipe.Because the surfaces externally and internally of hollow electric heating tube of the present invention can transmit water to heat, has increased the heat transfer area of unit power; Add cleaning bead and lower cleaning bead disturbance current, cold water and hot water and the interior cold water of water tank in the hollow electric heating tube are fully mixed with hot water.Greatly reduce the temperature of hollow electric heating tube surfaces externally and internally, the speed of the hollow electric heating tube surfaces externally and internally fouling of having slowed down.The surfaces externally and internally of coarse upper cleaning bead and the hollow electric heating tube of the little ball impact of lower cleaning rubs off the dirt of hollow electric heating tube surfaces externally and internally; Make hollow electric heating tube not by corrosion, increased the heat transference efficiency of hollow electric heating tube, prolonged the service life of hollow electric heating tube.
