Background technology
At present, water-storage electric heater cold water inlet device has welding and the dual mode of packing into from the cold water joint outside.The intake apparatus telotism of welding manner is effective, but is not suitable for the inner bag of all materials, and cost is higher.The mode of packing into from the cold water joint outside is applicable to the inner bag of all materials, but function is relatively poor, and the water outlet performance of water heater descends greatly.Owing to above reason, cause water heater leaving water temperature poor stability, need during use to adjust continually and mix water valve; After hot water used up, the temperature of the surplus water of inner bag was very high, near the temperature of shower warm water, caused the capacity usage ratio of water heater very low.
Summary of the invention
The purpose of this utility model provides a kind ofly makes that the water feed apparatus cost is low, water temperature stability, go out the water-storage electric heater water feed apparatus that water inventory is big, capacity usage ratio is high.
In order to achieve the above object, the utility model adopts following technical scheme: a kind of water-storage electric heater water feed apparatus, and the cup-shaped flange places in the water supply connector, and the flange middle part is the screw via hole, and the both sides of screw via hole are arcuate socket; Water fender is positioned on the madial wall of inner bag, and the both sides of water fender are jagged, and the screw via hole that screw passes flange is fixed on the water fender.
The screw via hole that described water fender middle part has screw fixed hole, screw to pass flange screws in the screw fixed hole of water fender.
Described water fender middle part is fixed by nut after having screw via hole, screw to pass the screw via hole of water fender.
The long 175-185mm of described water fender, wide 25-35mm.
Described flange depth 5-7mm.
Water fender in the utility model is flute profile, is about 180mm, wide about 30mm, and there is the less breach in cross section both sides, are convenient to current and pass through, and there are screw fixed hole or screw via hole in the centre.Cup-shaped load flange is installed in the water supply connector, cup-shaped load flange cup section external diameter is less than water inlet internal diameter 0.5mm, and flange outer diameter reduces 0.5mm than joint screw thread path, is convenient to mounting flange, and cup-shaped load flange is applicable to that the inner bag of any material installs, and the back is installed firmly.The load flange has the screw via hole in the middle of the bottom, is convenient to mounting screw, and there is half crescent shaped through hole both sides, are convenient to current and pass through.After the whole moulding of inner bag, water fender or water fender and hold-down nut are put into inner bag from the heating tube installing hole, and the load flange is put into joint from the outside of water supply connector with cup section, and screw passes the interstitial hole of load flange, screw in the screw hole of water fender, until tension; Or screw passes the screw via hole of water fender, with nut water fender is pressed on the inner bag inwall.Above-mentioned mounting structure is stabilized in inner bag inwall and the water supply connector whole water feed apparatus.
Owing to the utlity model has above-mentioned shape, structure and size and material requirements, thus can realize that cost is low, the water outlet water temperature stability, go out the purpose that water inventory is big, capacity usage ratio is high, and on the inner bag of all materials, can both keep identical complete function.
