Abstract
The utility model discloses an electric water heater that is composed of a shell, a liner is arranged inside the shell. The utility model is characterized in that two ends inside the liner are respectively arranged with a magnesium stick. As the magnesium sticks are arranged on the upper and lower ends or the left and right ends of the liner, the erosion-proof effect is better than that of the regular single magnesium stick; besides, the two magnesium sticks are used as the sacrificial anodes, thus the liner can be well protected and the service life of the liner can be prolonged.
Description
Technical field
The utility model relates to a kind of electric heater, particularly a kind of electric heater with magnesium rod.
Background technology
Electric heater is a kind of water heater that generally uses.Because inner container of electric water heater is made by metals such as steel, titanium steel, manganese steel; though insulating coating protections such as enamel, baking vanish are arranged; but coating can not be accomplished " flawless "; coating can wear out year by year simultaneously; and crackle or local shedding appear; water can produce corrosion to inner bag, so electrochemical anti-corrosive arises at the historic moment.Wherein a kind of is the sacrificial anode protection cathodic protection mode of using the protection of magnesium rod in electric heater; it is that metal inner tube is used as negative electrode; and the magnesium rod is used as anode; pass through the aqueous medium of conduction like this between negative electrode and the anode; form a galvanic cell; the anode of battery---the magnesium rod is corroded and autophage, and negative electrode---inner bag steel body just is protected.Crack or local damage when coming off at the inner bag enamel coating like this, inner bag can produce one deck passivating film, and it is the same with enamel layer, plays insulation and corrosion-resisting function.But because existing above-mentioned electric heater all just is equipped with single magnesium rod, unsatisfactory to the protection effect of inner bag, the service life of inner bag is shorter.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of result of use good, its inner bag long electric heater service time.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of electric heater comprises shell, is provided with inner bag in the shell, and the two ends within inner bag are separately installed with the magnesium rod.
The beneficial effects of the utility model are: owing to use the magnesium rod respectively at the two ends up and down or the two ends, the left and right sides of inner bag, better than general single magnesium rod antiseptic effect, two magnesium rods can well be protected inner bag as sacrificial anode, prolong the service life of inner bag.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation one of the present utility model;
Fig. 2 is a structural representation two of the present utility model.
The specific embodiment
With reference to Fig. 1, Fig. 2, a kind of electric heater comprises shell 1, is provided with inner bag 2 in the shell 1, two ends within inner bag 2 are separately installed with magnesium rod 3,4, magnesium rod as described has two, promptly constitutes two magnesium bar structures, wherein, this pair magnesium rod 3,4 can be separately positioned on the two ends up and down of inner bag, certainly, as required, also can be arranged on the two ends, the left and right sides of inner bag.
In addition, above-mentioned magnesium rod 3,4 can be installed on the inner bag by removable mode, when the magnesium rod, can be changed it after being depleted to certain degree along with the long-time use of product.
Certainly, the utility model is except the foregoing description, and other equivalent technical solutions also should be within the protection domain of the invention.
Claims (2)
1. an electric heater comprises shell (1), is provided with inner bag (2) in the shell (1), it is characterized in that: the two ends within inner bag (2) are separately installed with magnesium rod (3), (4).
