Description

Multipotency source water heater

Technical field

The utility model is related to family expenses and commercial central-heating atmospheric hot-water machine（Or normal-pressure hot-water boiler）.

Background technology

Existing north of China family expenses and commercial winter heating, mainly with coal heating, current government forbids using fire coal, Use air energy or combustion gas and auxiliary power instead, air can efficiency be very low at low temperature or can not work, and combustion gas just can be with Work, particularly carries out paddy peak electricity price in You20Duo Ge provinces and cities of China, from night 9 when, during to morning 6, the electricity charge every thousand Watt/when, only need 0.2-0.3 members；Its usage charges is all lower than any energy, but existing gas water heater, can only use combustion gas, it is impossible to make With electric power, low price electric power can not be used, because not using the function of various energy resources.

Utility model content

The purpose of this utility model is to design a kind of hot water machine of multiple-energy-source（Or to be also referred to as modular normal for normal-pressure hot-water boiler Hot-water boiler is pressed, similarly hereinafter）Combustion gas is both used to water heating, it is possible to use electric power, particularly can use low price electric power, and can and air Source heat pump is applied in combination；Realizing can source heating with three kinds.

Technical measures of the present utility model are that multipotency source water heater is adjusted by burner 1, heat exchanger 2, blower fan 3, combustion gas Proportioning valve 4, condensing heat exchanger 5, cold water inlet 6, hot water outlet pipe（Or mouth）7th, water flow sensing unit 8, solenoid directional control valve 9, water Pump 10, water tank 11, electrothermal tube 12, gas inlet pipe 13, intelligent controller 14, domestic hot-water's pipe 15, heating water return pipe（Or Mouthful）16th, thermometric and the warm pipe 17 of limit, shell 18, check valve 19, water 20 are constituted；Wherein, burner 1, heat exchanger 2, blower fan 3, combustion Controlled atmosphere section proportioning valve 4 constitutes gas heating mechanism；Water tank 11 and built-in electrothermal tube 12 are electric heating mechanism.

The water tank, is that the expansion tank in existing hot water machine is improved, existing expansion tank only one of which mouthful with Water route is communicated, for adjusting the pressure in closed loop, after improvement, equipped with 1 or more electrothermal tube 12 in water tank 11, is also had Hot water outlet pipe 7, water inlet and water outlet are arranged at water inlet of hot water and heating water water return outlet, the top of water tank, form a path, water tank There is compressible air 37 on top, for adjusting the pressure in closed loop.

It is mainly used in family's heating and domestic hot-water supply shown in the utility model Fig. 1 and Fig. 2, also can be with air source heat pump group Conjunction is used, and the thermal source that its multipotency source water heater is heated to water is made up of gas heating and the part of electrical heating two, the gas heating, After the ignition of burner 1, current over-heat-exchanger 2 is heated to after temperature in use, is flowed into water tank 11, and through water tank, Floor heating or radiator heating passage are sent into by hot water outlet pipe 7, water temperature is reduced after radiating, through heating return pipe 16, by water pump 10, return to heat exchanger and heat again, constantly circulation, now constitute loop.

The electrical heating is the electrothermal tube 12 in water tank 11, after energization, i.e., the water in water tank is heated, electrothermal tube 12 in night low power consumption, cut-out or reduction combustion gas, automatically using low-price electricity.

This product uses paddy peak electricity price, night 9 was up to second day due to can use various energy resources in Chinese You20Duo Ge provinces and cities During morning 6, electricity price only needs 0.09-0.3 members；This patent product is entered within this period by controller 14 to regulating gas proportioning valve 4 Row regulation, automatically cuts off combustion gas or closes combustion gas to minimum, and changes to using low-price electricity.

Fig. 3 is that modular multipotency source water heater is applied in combination with air source hot pump water heater, and gas heating part uses mould Blocking structure, there is multiple burners, multiple heat exchangers, multiple gas ratio valves,（Fig. 2 is also similar structures）Realize large area In central heating, figure, left side is that the bottom of multipotency source water heater 18 sets water tank 11, and right side is air source hot pump water heater 18-1； Hot water produced by hot water and right hand side air energy heat pump that two, left side heat exchanger 2 is produced, injects in water tank 11, and lead to Superheated water outlet pipe 7, into radiator 35 or floor heating 36, after radiating, reduces the water of temperature, and by water pump 10, sends reheating back to, Constantly circulation；Winter when air source heat pump is because of the very inefficient difference of temperature or when can not work at all, can automatic electrothermal tube 12, Electrified regulation, or have paddy electricity, combustion gas can be closed or turned down automatically, the cheap electric power of low ebb is used instead；Therefore the design is respectively adopted Air energy, combustion gas and electric three kinds of energy are heated to water.

Water tank 11, which is used outside metal or nonmetallic making, built-in 1 or more electrothermal tube 12, electrothermal tube, metal or non-gold Belong to sleeve pipe 31, metal or non-metallic casing are firmly connected with water tank for sealing, be to be communicated in water, sleeve pipe with air 32 outside sleeve pipe, Sleeve pipe 31 externally opens wide for two ends, or it is blind pipe that the other end is externally opened wide in one end（Blind hole sleeve pipe, opens wide one end and connects with tank seal Connect）；The electrothermal tube 12 is to have heating wire 41 in non-metallic pipe 46, and there is eduction rod 42 at two ends（Fig. 2）, or heating wire 41 is in non-gold Category blind pipe in bend to U-shaped, two eduction rods are drawn in same one end, when bending to U-shaped, must have an insulated body 43 every From preventing short circuit（Fig. 3 Fig. 4）；During energization, dry combustion method in air of the heating wire in non-metallic pipe；Or electrothermal tube 12 is non- In metal tube, the internal carbon fiber or halogen electrothermal tube 44 vacuumized of dress（Fig. 5 brings out line for two, and Fig. 6 brings out line to be same）；By In the air that electrothermal tube 12 is installed in metal or non-metallic casing, when maintenance is changed, it is not necessary to discharge water.

The beneficial effects of the utility model are that various energy resources can be used, and expense is applied in combination than relatively low with air source heat pump, uses Combustion gas and electricity, it is ensured that air-source under any low temperature environment all can heating, and installation fee can reduce by 40%, meanwhile, night makes With low-price electricity, both the night unnecessary electric power for state consumption, reduced usage charges again.
