Wherein, the inner container (1) comprises a metal lamellar (1), and a plastic layer (13), which are bonded into a whole. The heating element (5) comprises a silicon nitride ceramics (51), a tungsten wire (52), electrodes (53,53A), insulating heat proof laggings (54, 54A) and conductors (55, 55A), wherein the tungsten wire (52) is arranged in the silicon nitride ceramics (51), the electrodes (53, 53A) are respectively connected to the two ends of the tungsten wire (52), and the insulating heat proof laggings (54, 54A) are respectively wrapped around the electrodes (53,53A) which are connected to the power supply respectively by the conductors (55,55A). The utility model is not only dry burning resistant, corrosion of strong acid and strong alkali resistant, water scale resistant, high and low temperature resistant, but also has a long service life.
Description
1, technical field:
The utility model is a kind of water-storage electric heater, belongs to the renovation technique of water-storage electric heater.
2, background technology:
Water-storage electric heater is used enamel inner container always at present, and enamel inner container is promptly warded off last layer enamel on the inner bag inwall that general steel plate is made, to strengthen the corrosion resistance of inner bag.The shortcoming of its existence is no matter adopt which kind of enamel technology, because enamel layer is very thin, enamel defect is difficult to again detect, so reduced the corrosion resistance of enamel inner container.The heater of water-storage electric heater adopts common electrothermal tube mostly at present, the shortcoming of its existence is that anti-dry combustion method, high-low temperature resistant, shock resistance and vibration ability are poor, easily corroded by strong acid and strong base, and after using a period of time, heating element heater surface meeting scaling, service life is short.Can't guarantee the service life of electrothermal tube and inner bag, be the two big inherent shortcomings that present water-storage electric heater exists the service life that can't detect concrete parts, for this reason, producer can only be from the probabilistic manner on the statistics, predict the average quality level of entire block according to the use zone (mainly being relevant) of product, to stipulate user's service life with water quality.
3, summary of the invention:
The purpose of this utility model is to overcome above-mentioned shortcoming and a kind of not only anti-dry combustion method, anti-strong acid-base burn into preventing scale deposite, high-low temperature resistant is provided, and the novel water-storage electric heater of long service life.
Structural representation of the present utility model as shown in Figure 1, include inner bag (1), heating element heater (5), heat-insulation layer (6), inner bag (1) is provided with delivery port (3) and water inlet (4), heating element heater (5) places the bottom of inner bag (1), heat-insulation layer (6) is wrapped in the outside of inner bag (1), wherein inner bag (1) includes sheet-metal layers (11), plastic layer (13), and sheet-metal layers (11) is bonded as one by adhesive layer (12) with plastic layer (13).
Above-mentioned heating element heater (5) is the ceramic electric heating element.
Above-mentioned heating element heater (5) includes silicon nitride ceramics (51), tungsten filament (52), electrode (53,53A), insulation collet (54,54A) and lead (55,55A), wherein tungsten filament (52) places in the silicon nitride ceramics (51), electrode (53,53A) is connected to the two ends of tungsten filament (52), insulation collet (54,54A) is nested with respectively on electrode (53,53A), and electrode (53,53A) is connected with power supply by lead (55,55A) respectively.
Above-mentioned silicon nitride ceramics (51) and tungsten filament (52) compression moulding under high temperature, high pressure.
Above-mentioned inner bag (1) is provided with sewage draining exit (2).
The utility model is because the structure that adopts steel to mould composite inner liner, its high-low temperature resistant, strong alkali-acid resistance, shock-resistant, corrosion resistance and good, and employed plastic material is nontoxic in the time of can guaranteeing to use for a long time, free from extraneous odour, nothing are rotten, meets state health standards.And the magnesium rod that is used for inner bag protection need be installed, not have the problem that needs periodic replacement magnesium rod, can avoid the inner bag corrosion to cause the generation of the great quality problems of leaking.Compare with enamel inner container, the thickness of its plastic layer can be greater than 2mm, short of sharp-pointed burr, just there is not the possibility of revealing iron, as long as the weld seam of inner bag is air tight, even exist very big weld seam can carry out " rotational moulding " processing yet, be service life 10 years, and because of inner bag adopts rotational molding technique, to the machinery and the significantly reduction (planarization and the outward appearance aspect that mainly refer to weld seam) of welding processing requirement of inner bag, so can effectively lower production cost.In addition, heater of the present utility model is owing to adopt the silicon nitride heater element, and abilities such as its anti-dry combustion method, anti-strong acid-base burn into preventing scale deposite, high-low temperature resistant are good.Under normal situation about using, how long no matter to use, the heating element heater surface is scaling for a long time not, and comparing with common metal pipe heating element heater increases service life greatly.The utility model is that a kind of design is ingenious, rational in infrastructure, the novel water-storage electric heater that serviceability is good.
