Description

Water storage electrical heating wall-hung boiler

Technical field

The utility model is related to the water storage electrical heating wall-hung boiler of domestic heating and domestic hot-water（Hereinafter referred to as electric wall-hung boiler）.

Background technology

Existing family's winter heating, mainly realizes heating and provides domestic hot-water with wall-hung boiler；Wall-hung boiler uses combustion Gas, paddy peak electricity price is carried out in You20Duo Ge provinces and cities of China, from night 9 when, during to morning 6, every kilowatt of the electricity charge/when, only Need 0.2-0.3 units；Its usage charges is all lower than any energy, but existing wall-hung boiler, can only use combustion gas, it is impossible to use electric power, less Low price electric power can be used, it is therefore desirable to develop a kind of water storage electrical heating wall-hung boiler；Meanwhile, water heater is indispensable every household Electrical equipment, present patent application be on the basis of existing storage-type electric water heater, increase heating function.

Utility model content

The purpose of this utility model is that existing storage-type electric water heater is improved, and is realized for life as water storage electricity wall-hung boiler Hot water and heating hot water living；Electric wall-hung boiler is by shell and heating water tank, expansion tank, heat-exchangers of the plate type, water inlet pipe（Or mouth）、 Hot water outlet pipe（Or mouth）, water flow sensing unit, water pump, intelligent controller constitute；Heated using electric power after improvement, in the paddy electricity period Use low price electric power.

Technical measures of the present utility model are, in electric wall hanging stove outer covering, have the heating water tank for heating water, in water tank 11 Inner or outer that 1 or more electrothermal tube 3 is housed, water tank has water inlet 6, and there are hot water outlet pipe 7, water inlet and water outlet in top, form one Individual path；Have water 13 in water tank, the top of water have can compressed air 14, or swelling water is set in heating circulation water road Heating, by heating return pipe 16, floor heating 21 and radiator 22 are reduced case, water pump 9 water of temperature after, send into water In case, mix with high-temperature-hot-water, delivering to heating pipeline further through heating outlet pipe 7 after raising temperature constantly circulates；Life is used Hot water, can be set domestic hot-water's case 11-1 or uses heat-exchangers of the plate type 17.

In or beyond electric wall-hung boiler water tank 11, the electrothermal tube 3 for being filled after energization, i.e., is heated to the water for flowing through water tank； To the paddy electricity period, low ebb electrical heating is used, when heating system water temperature is too low, electrothermal tube meeting turn on automatically, and automatically adjust out water temperature Degree.

Fig. 1 to Fig. 5 only one of which water tanks, domestic hot-water's heat-exchangers of the plate type；Fig. 6, Fig. 7 have 2 water tanks, and one is to supply Heating water tank 11, another supplies domestic water case 11-1, domestic water facility is delivered to by domestic hot-water's pipe 15, can be with board-like Heat exchanger substitutes the water tank of domestic water.

Water tank 11 and 11-1, using metal or nonmetallic making, heating with water tank capacity it is larger when, have water using inside, Compressible air is arranged at the top of water, can simplify structure.

There is 1 or more electrothermal tube 3 in heating water tank 11 in Fig. 1 to Fig. 5, there is metal or non-metallic casing 4 outside electrothermal tube, Metal or non-metallic casing, for sealing is firmly connected, are water outside sleeve pipe with water tank, and sleeve pipe 4 is externally opened wide for two ends, or one end pair The unlimited other end is blind pipe outward, during using blind hole sleeve pipe, opens wide one end and is connected with tank seal；Domestic hot-water uses plate-type heat-exchange Device 10, non-heating season degree closes the path of heating apparatus by change-over switch 5, hot water is returned directly in water tank；Fig. 3, Fig. 5 Water tank upper has compressible air 14, therefore is not required to use expansion tank；Fig. 6 Fig. 7 domestic hot-waters use independent domestic hot-water Case 11-1, it is not necessary to plate type heat exchanger.

During Fig. 8 to Figure 12 is water tank 11, the electrothermal tube that can be used, the electrothermal tube 3 is have electric heating in non-metallic pipe 3-1 Silk 3-2, there is eduction rod 3-3 at two ends, or heating wire 3-2 bends to U-shaped in nonmetallic blind pipe, and two eduction rods draw in same one end Go out, when bending to U-shaped, there must be an insulated body 3-4 to isolate, prevent short circuit；Should be sealed at eduction rod, take out low true in pipe Empty or non-combustible, the not combustion-supporting gas of injection or inert gas load non-closely knit magnesium oxide powder and air 3-5（It is in pipe During air, can be with blow-by）；Or carbon fiber or halogen electrothermal tube are directly filled in sleeve pipe 4.

Fig. 7 is that have 1 or more electrothermal tube 3 on tank outer wall, and the outer tube of electrothermal tube is metal material, inside there is heating wire, With magnesium oxide powder by heating wire and metal pipe-wall isolated insulation；Electrothermal tube welding method, be welded in water tank outer surface, not with Water is in contact, and is water proof heating during work.

The beneficial effects of the utility model are electric wall-hung boilers, are heated using water proof in water tank, and safely and fast, night uses low Valency electricity, both the night unnecessary electric power for state consumption, reduced usage charges again.
