Description

Combustion gas and electrical heating wall-hung boiler

Technical field

The present invention relates to domestic heatings and the wall-hung boiler of domestic hot-water.

Background technology

Existing family's winter heating is mainly realized with wall-hung boiler and provides domestic hot-water for warm；Wall-hung boiler uses combustion Gas, in China, You20Duo Ge provinces and cities carry out paddy peak electricity price, from night 9 when, until during morning 6, every kilowatt of the electricity charge/when, only Need 0.2-0.3 first；Its usage charges is all lower than any energy, but existing wall-hung boiler, can only use combustion gas, it is impossible to using electric power, less Low price electric power can be used, because not using the function of various energy resources.

The content of the invention

The purpose of the present invention is improving burnt gas wall hanging furnace, proportioning valve is adjusted by burner 1, heat exchanger 2, wind turbine 3, combustion gas 4th, heat exchanger 5, cold water inlet 6, hot water outlet pipe（Or mouth）7th, water flow sensing unit 8, water pump 9, expansion tank 10, water tank 11 （Or aquaporin is similarly hereinafter）, gas inlet pipe 13, intelligent controller 14, domestic hot-water's pipe 15, heating water return pipe（Or mouth）16、 Shell 18 is formed；Both with combustion gas after improvement, also using electric power, in the paddy electricity period with low price electric power.

The technical measures of the present invention are, in existing wall-hung boiler, increase water tank 11, are arranged on middle heating water water return pipeline 16 To the pipe-line system of hot water outlet pipe 7, equipped with 1, with upper electrothermal tube 12, water tank has water inlet in or beyond water tank 11, and top has Hot water outlet pipe 7, and water inlet and water outlet form an access.

The heat source of wall-hung boiler of the present invention be two kinds of heat sources of gas heating and electrical heating, the gas heating, by burner 1, Heat exchanger 2, wind turbine 3, combustion gas adjust proportioning valve 4, gas inlet pipe 13 and form, and during using combustion gas, water tank is hot water channel.

The electrical heating is performed by the electrothermal tube 12 in or beyond water tank 11, filled, after energization, i.e., to flowing through water tank Water is heated；The paddy electricity period generally is set to, with low ebb electrical heating, at this point, cutting off or reducing combustion gas, is used automatically at a low price When electricity or too low heating system water temperature, electrothermal tube can turn on automatically；The regional electricity price having is very low, can directly use electrical heating.

Heat exchanger 2 shown in Fig. 1 is binary channels, and heating water and domestic water are respectively with different passages.

Water tank 11 has water using metal or nonmetallic making, inside；The structure of water tank has following form：

1. there is 1 or more electrothermal tube 12 in Fig. 1 in water tank 11, there are metal or non-metallic casing 31, metal or non-outside electrothermal tube Metal sleeve is securely connected with water tank for sealing, and casing is outside water, and casing 31 externally opens wide for both ends or one end is externally opened wide separately One end is blind pipe, during using blind hole casing, opens wide one end and is connected with tank seal；Figure 11 to Figure 17 is in Fig. 1 water tanks 11, can be with The electrothermal tube 12 of use, for the electrothermal tube 12 to have heating wire 3-2 in non-metallic pipe 3-1, there are eduction rod 3-3 or electric heating in both ends Silk 3-2 bends to U-shaped in nonmetallic blind pipe, and two eduction rods are drawn in the same end, when bending to U-shaped, must there is a quilt Insulator 3-4 isolates, and prevents short circuit；Or electrothermal tube 12 is in non-metallic pipe, equipped with what is made by carbon fiber or halide torch Electrothermal tube.

2. Fig. 2 to Fig. 5 is that have 1 or more electrothermal tube 12 on 11 outer wall of water tank, the outer tube of electrothermal tube is in metal material There is heating wire, with magnesium oxide powder by heating wire and metal pipe-wall isolated insulation；The method of the effective welding of electric heating, is welded in outside water tank Surface is not in contact with water；Fig. 2 is outline drawing, and Fig. 3 is the top view of Fig. 2, and Fig. 4 is the A-A sectional views of Fig. 2, and Fig. 5 is Fig. 4 Sectional view.

The beneficial effects of the invention are as follows usable combustion gas, it is possible to use and electric power, combustion gas on daytime, night use low-price electricity, Not only it is state consumption night extra electric power, but also reduces usage charges.

Description of the drawings

Fig. 1 is the wall-hung boiler for having electric heating water tank；

Fig. 2 is welded with the water tank of electrothermal tube to Fig. 5 outer walls；

Fig. 6 to Figure 10 is the different water tanks that can be mounted in wall-hung boiler；

Figure 11 to Figure 17 is available electrothermal tube in water tank in Fig. 1.

Specific embodiment

It is wall-hung boiler in box, left side generates hot water section for burning gases, and right side is water tank, and water tank can be installed in Fig. 1 In the back or side of combustion component；It is the schematic diagram using hot water facility outside box, it is three-way water mixing valve 33, raw in attached drawing Apply flexibly water spot 34, radiator 35, floor heating 36, smokejack 38, pressure release and discharge outlet 40.

Fig. 2 to Fig. 5 is to be welded with electrothermal tube 12 on 11 outer wall of water tank, is water proof heating.

Fig. 6 to Figure 10 is several different cisten mechanisms, can be used as the water tank of wall-hung boiler, each water tank can In wall-hung boiler, heated for electric power during night paddy electricity；Fig. 6 is different to cisten mechanism shown in Fig. 10, electric heating Pipe is also different；Compared with Fig. 1 and Fig. 2, Fig. 1 Fig. 2 is water proof heating, and security is very high.

The water tank or water stream channel of electric-heating water also have following several structure types：

In Fig. 6 water tanks 11, the electrothermal tube filled is that have heating wire in metal tube, with magnesium oxide powder by heating wire and metal tube every From insulation；It ducks in drink due to invading for a long time, breakdown can be corroded.

Fig. 7 is by stainless steel electrothermal tube 12 and water stream channel 11, passes through gravitational casting or the side of die casting with the aluminium water of fusing Method, electrothermal tube and aquaporin are combined as a whole formed water tank.

Fig. 8 is that one or more layers heating wire 3-2 is encased isolated insulation with mica sheet, and two outsides are pressed from both sides again with water stream channel 11 Tightly it is configured to water tank.

Fig. 9 is to plate conductive material outside in non-metallic pipe for water stream channel 11, tube wall, is the water flowed through in heating tube after energization The water tank formed.

Figure 10 is that positive temperature coefficient PTC thermo-sensitive material ceramic heating assemblies are made heater, and similar electrothermal tube, both sides are The water tank that water stream channel 11 is formed.

Present patent application, keypoint recommendation Fig. 1, Fig. 2；Fig. 6 to Figure 10 within protection, because respectively there is some shortcomings, will also be filled out Gravity treatment is used.
