Description
Technical field
The present invention relates to a kind of electric water boiler technical field.
Background technology
Existing electric water boiler, as: insulating pot, electric water-boiling device (bottle) etc., the heaters such as the how logical employing electrothermal tube of its Electric heating, electric hot tray, directly heat (water storage) inner bag; But the electric water boiler of above-mentioned traditional structure, has the following disadvantages: (1) adopts above-mentioned heater, cannot realize Instant heating type, needed for drinking at any time for people; (2) inner bag is equipped with by the boiling water boiled, if can not drink in time, temperature will affect drinking of boiling water, such as cannot be used for makes tea drinks after reducing; (3) be stored in the water of inner bag, drink if fail, water is wasting, loss electric energy.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, and provide a kind of simple and reasonable for structure, the dry combustion method of coating film on glass electrothermal tube can being prevented, both immediately for drinking, energy-conservation, safety can have been had again concurrently, the electric water boiler that the mouthfeel of boiling water is good.
The object of the present invention is achieved like this:
A kind of electric water boiler, comprise storage tank and faucet, it is characterized in that, also include balanced reservoir and coating film on glass electrothermal tube, the delivery port of storage tank is communicated with the water inlet of balanced reservoir, the delivery port of balanced reservoir connects the water inlet of coating film on glass electrothermal tube, and faucet is communicated with the delivery port of coating film on glass electrothermal tube, other temperature controller and/or the fuse being also provided with anti-dry of described coating film on glass electrothermal tube; This kind of electric water boiler, by using coating film on glass electrothermal tube as electric heater unit, outer wall in view of coating film on glass electrothermal tube is provided with the metal level of heating power, and glass tube inner chamber passes through pipeline as current, therefore, each independent tube chamber in glass tube, passes to rapidly the intraluminal water of each independence by metal level heating by heat, to realize the effect of immediately boiling, be convenient for people to drink at any time; And easily produce incrustation scale in common metal pipe, glass tube inner chamber is then not easy to produce incrustation scale, the boiling water excellent taste that it boils, and is especially applicable to the requirement of high-end drinking-water, as: make tea; More have plenty of, in view of coating film on glass electrothermal tube is Instant heating type, therefore, user drinks how much water, just burns how much water, and guarantee can not cause waste, saves electric energy.
Object of the present invention can also adopt following technical measures to solve:
As better embodiment, the height of water level of described balanced reservoir is lower than the level height 2mm to 15mm of heater delivery port, especially be the height of water level of balanced reservoir lower than coating film on glass electrothermal tube delivery port 8mm time, its effect is better, ensure that boiling water out reaches 100 degree, its reason is, water to be heated is fed in coating film on glass heater, but, by balanced reservoir height limitation, when water in coating film on glass electrothermal tube remains on lower than water outlet 8mm, when water is heated (boiling water), effects of air pressure can be subject to, constantly release toward water outlet height, once water let out delivery port, water then in pipe is sure is heated to boiling, that is: the water of boiling can stride across the height space of 8mm, avoid because this height space is because of too low or too high, and the various defects caused, as: when height space is too low, hot water only has 80 degree just to flow out, when height space is too high, full 100 degree of hot water is also difficult to flow out, and causes and wastes energy.
As embodiment more specifically, it also includes water pump, and storage tank is in below, and up, water pump connects storage tank delivery port and balanced reservoir water inlet by water pipe to balanced reservoir; During drinking-water, people press the switch of boiler, and water pump obtains electric work, and by the water suction in storage tank to balanced reservoir, balanced reservoir flows into the water inlet of coating film on glass electrothermal tube, immediately heats, for drinking.
As more perfect scheme, bottom described balanced reservoir, have the water return outlet being communicated with storage tank; For making the water in balanced reservoir keep height of water level, unnecessary water flows back to storage tank by water return outlet, and water pump, again by the water suction balanced reservoir in storage tank, so repeatedly, forms water circulation system, reaches more stable water balance water level (in balanced reservoir).
