The technical scheme is: there is a burner in the stove, and a pot ring is arranged on the upper part; a flue is arranged in the furnace body, a water tank is arranged outside the flue, a smoke exhaust hole is arranged in the pot ring, and there is a connecting smoke exhaust hole and a water tank between the burner and the water tank. Gaps in the flue. The rear part of the water tank protrudes upwards, and several chimneys are arranged on the protruding part to be connected with the flue. The utility model can be applied to various cooking stoves.

Description

Cooking stove

Technical field

The utility model relates to a kind of cooking stove, particularly a kind of cooking stove that has pre-heat utilization device.

Background technology

Cooking stove is the kitchen range that are used for cooking in people's daily life.Cooking stove includes body of heater, is provided with burner in body of heater, and body of heater is provided with the pot circle, when cooking stove uses, pot is placed on the pot circle, and fuel is in the burner internal combustion, and the heat of generation heats pot.In the present known cooking stove, air blast is blown into burner to provide fuel combustion required oxygen with air; The hot flue gas that the burning back produces directly enters air.In known cooking stove, because directly entering burner, cold air participates in burning, cause combustion efficiency bad, fuel can not completing combustion; And the hot flue gas that the burning back produces directly enters air, and heat energy wherein is wasted.Known cooking stove existence wastes energy and the air-polluting problem.

In industrial boiler, much all equipped residual heat using device, to the heat recovery in the flue gas, and the mode by heat exchange is discharged thermal energy transfer in the flue gas to boiler in the air that enters boiler, improved the air themperature that enters boiler, improve the working condition of boiler, make fuel combustion more complete, energy savings also reduces air pollution.The residual heat using device complex structure that uses on the Industrial Boiler, cost height, volume are big, are difficult to be suitable in Civil energy-saving cooking stove.

Summary of the invention

Directly enter air in order to solve the existing hot flue gas of cooking stove, thermal pollution to air is wasted and caused to heat energy in a large number, cold air is participated in burning directly and is caused combustion efficiency bad, cooking stove wastes energy and air-polluting problem, the utility model provides a kind of cooking stove that has pre-heat utilization device, this cooking stove is provided with the UTILIZATION OF VESIDUAL HEAT IN water tank and reclaims and provide hot water to the waste heat in the flue gas, the hot flue gas heating that utilizes the burning back to produce simultaneously enters the air of burner, improve the temperature of the air that participates in burning, improve combustion position, promoted fuel completing combustion; Energy savings has also reduced air pollution.

The technical scheme that its technical problem that solves the utility model adopts is:

Burner is arranged in cooking stove, and body of heater is provided with the pot circle; Flue is set in body of heater, and flue is provided with the UTILIZATION OF VESIDUAL HEAT IN water tank outward, in the pot circle exhaust smoke hole is set, and the space that connects exhaust smoke hole and flue is arranged between burner and water tank.The water tank rear portion projects upwards, and at ledge some chimneys is set and links to each other with flue.

When using this cooking stove, air enters the burner air compartment from blast pipe, is participated in burning by hot flue gas heating back in air compartment.The hot flue gas that burning produces enters flue through exhaust smoke hole, contacts with the UTILIZATION OF VESIDUAL HEAT IN water tank with the burner air compartment at flue, and air in the burner for heating air compartment and the water in the UTILIZATION OF VESIDUAL HEAT IN water tank are discharged through chimney then.Cold air in the burned device air compartment of a heat part in the flue gas absorbs, and a part is absorbed by the water in the water tank, has reduced the temperature of discharging flue gas, has reduced thermal pollution.Simultaneously, owing to the air themperature that enters burner is higher, better when combustion position directly enters than cold air, fuel combustion is more abundant, has avoided unburnt situation, has reduced air pollution.High temperature air also makes the less fuel of burner dissipated can reach the higher temperature that satisfies instructions for use, has reduced fuel consumption, energy savings.

The beneficial effects of the utility model are:

Reclaim the heat energy in the flue gas, reduce the temperature of discharging flue gas, energy savings reduces and pollutes; Improve the air themperature that enters burner, improved combustion position; Simple in structure, make easily, cost is low.

The specific embodiment

Fig. 1 to Fig. 6 is the schematic diagram of an embodiment of the utility model.As shown in the figure: be provided with burner 1 in cooking stove, burner 1 is provided with air compartment 11, fuel feed pipe 12 and blast pipe 13; Pot circle 3 is set on cooking stove; Be provided with flue 5 in the body of heater, flue is provided with UTILIZATION OF VESIDUAL HEAT IN water tank 2 outward; In pot circle 3, be provided with exhaust smoke hole 31; Between water tank 2 and burner 1, leave the space that connects exhaust smoke hole 31 and flue 5; Water tank 2 rear portions project upwards, and at ledge some chimneys 21 are set and link to each other with flue 5.When using cooking stove, air enters burner air compartment 11 by blast pipe 13, is entered burner 1 after the hot flue gas heating in the flue 5 to participate in burning; The hot flue gas that burning produces enters flue 5 by exhaust smoke hole 31 through space between water tank 2 and the burner 1, to the air heat in water in the water tank 2 and the air compartment 11, discharges through chimney 21 then.Present embodiment has reclaimed the heat in the flue gas, has reduced the temperature of discharging flue gas; Improve the air themperature that enters burner 1, improved combustion position; Have energy savings, reduce the effect of polluting; Present embodiment is simple in structure, making is easy, cost is low.
