Description

A kind of water heater

Technical field

The utility model relates to a kind of water heater.

Background technology

Water heater is the device of a kind of hot-water supply at present commonly used, because its general cost is not high, operating cost is low, therefore in the residential block, enterprise and industrially all be used widely.The water heater that uses adopts coal to make fuel mostly at present, the flue-gas temperature that gives off after the burning is up to 350～400 degrees centigrade, if so the flue gas of high temperature directly is discharged in the air, not only cause the huge waste of heat, also very serious to the pollution of environment simultaneously.A kind of method can connect a heat exchanger at the flue outlet place, the recovery section waste heat, but can cause equipment complicated like this, manufacturing cost also can rise simultaneously.

Summary of the invention

The purpose of this utility model be for provide a kind of simple in structure, heating rapidly, wide, the energy-efficient water heater of applicability.

The main technical schemes that the utility model adopts is: be fixed with the combustion chamber on the base in this water heater main body water tank, offer the fire door that communicates with described combustion chamber on the main body water tank, lead smoke-box and be arranged on the top of described combustion chamber, smoke exhaust pipe one end is communicated with the described smoke-box other end of leading and passes case lid and stretch out outside the described main body water tank, flue tube is communicated with described combustion chamber and the described smoke-box of leading, and this is led and is fixed with high-temperature heat-gathering device in the smoke-box.

Described high-temperature heat-gathering device comprises inner chamber, be fixed on flue tube that augmentation of heat transfer sheet, this inner chamber of up/down perforation and the lower end of cavity outer wall in this communicate with described combustion chamber, be positioned at the suction hose that this intracavity bottom communicates with described main body water tank and be positioned at this inner chamber top and pass the described circulation pipe of leading the smoke-box top and stretching into described main body water tank, and outlet pipe is communicated with described inner chamber.

Described augmentation of heat transfer sheet is fin shape or corrugated.

Described case lid is provided with steam vent and water cover, is discharged by steam vent when producing small amount of steam, and when a large amount of steam produced, steam can back down water cover automatically.

Described main body water tank water inlet is equipped with into the water management ball-cock assembly.

The utlity model has following significant advantage: (one) can fully absorb the waste heat of flue gas, accomplishes the reasonable utilization of waste heat.Lead smoke-box and be placed on the top middle position of combustion chamber, the heat energy that makes the combustion chamber the produce absorption of at once feeding water; Form by the augmentation of heat transfer sheet around the high-temperature heat-gathering device, can increase endotherm area, absorb the heat in the high-temperature flue gas; The flue tube of augmentation of heat transfer sheet and high-temperature heat-gathering device inner chamber is passed to contained heat the water of inner chamber jointly, to the water formation post bake of this inner chamber; Simultaneously smoke exhaust pipe adopts bend pipe structure, and the maximum function of this structure is to postpone the time that the coal smoke waste heat energy stops in water, and heat is passed to water in the main body water tank.(2) firing rate is fast.The utility model can maximally utilise the waste heat of flue gas, and the water in the water heater is formed post bake, and therefore, under equal heating condition, the water temperature rate of climb is very fast.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is the structural representation of an embodiment of the present utility model;

Fig. 2 is the structural representation of leading among Fig. 1 after smoke-box amplifies.

The specific embodiment

As shown in Figure 1, be fixed with combustion chamber 2 on the base 1 in the present embodiment in the water heater main body water tank 3, offer the fire door 16 that communicates with combustion chamber 2 on the main body water tank 3, lead smoke-box 9 and be arranged on the top of combustion chamber 2, smoke exhaust pipe 8 one ends are communicated with leads smoke-box 9 other ends and passes case lid 5 and stretch out outside the main body water tank 3, flue tube 4 is communicated with combustion chamber 2 and leads smoke-box 9, leads in the smoke-box 9 and is fixed with high-temperature heat-gathering device.The flue tube 11 that high-temperature heat-gathering device comprises inner chamber 10, is fixed on the augmentation of heat transfer sheet 12 of inner chamber 10 outer walls, up/down perforation inner chamber 10 and lower end communicate with combustion chamber 2, be positioned at suction hose that inner chamber 10 bottoms communicate with main body water tank 3 13,13 ' and be positioned at these inner chamber 10 tops and pass the circulation pipe 15,15 ' of leading smoke-box 9 tops and stretching into main body water tank 3, outlet pipe 14,14 ' is communicated with inner chamber 10.

Augmentation of heat transfer sheet 12 can be fin shape or corrugated, case lid 5 is provided with steam vent 6 and water cover 7, is discharged by steam vent 6 when producing small amount of steam, when a large amount of steam produce, steam can back down water cover 7 automatically, is equipped with into the water management ball-cock assembly at main body water tank 3 water inlets.

Operation principle of the present utility model is as follows: water is by going into after the water management ball-cock assembly enters main body water tank 3, enter in the inner chamber 10 by suction hose 13,13 ' again, put into combustion chamber 2 internal combustion with fuel this moment, heat directly passes on the water and augmentation of heat transfer sheet 12 of inner chamber 10 by top of combustion chamber, water in the inner chamber 10 is after heating, because the proportion of hot water and cold water is different, hot water is just through circulation pipe 15,15 ' ejection, this moment, suction hose 13,13 ' was also served as the function of moisturizing, ceaselessly, just form hot and cold water circulating exchange up and down by this rule running.When using hot water, hot water flows out for using through water nozzle through outlet pipe 14,14 ' again.Main body water tank 3 usefulness insulation materials are made, and prevent the waste of heat energy.

A flue gas part that produces in the combustion chamber 2 arrives through flue tube 4 and leads in the smoke-box 9, the waste heat of flue gas was reinforced heat transfer sheet 12 and absorbed once more this moment, water in the inner chamber 10 is formed post bake, another part flue gas flue tube 11 of directly flowing through further heats the water in the inner chamber 10 in this process equally.Flue gas is discharged through smoke exhaust pipe 8 after flue tube is discharged again.This smoke exhaust pipe 8 adopts bend pipe structures, and smoke exhaust pipe 8 main parts are placed in the main body water tank 3, the water in the main body water tank 3 is also further heated in discharge process through the flue gas of smoke exhaust pipe 8, guarantees that waste heat is absorbed as far as possible.
