Description

Energy-saving cooking

Technical field

The present invention relates to a kind of energy-saving cooking.

Background technology

The combustion system of gas-cooker of Chu Shouing or oil range all is open burning generally in the market, and promptly stone or metal plate for standing a stove on as a precaution against fire exposes, and flame directly contacts with surrounding air during burning, does not have any retaining closed structure and heat reclamation device.The flare of general gas kitchen range is at random unable, and what active force the bottom of a pan is not almost had, and can be described as to edge away, and the heat energy utilization rate is extremely low, and fire is gone hither and thither along the bottom of a pan, and the flare that overflows along the pot limit is taken away a large amount of heats, and it is very serious to cause heat to run off; Because its design defect, the fuel of inside, combustion zone can not well contact with air, causes the incomplete combustion of fuel.So it is low and energy waste is more serious that common kitchen range use efficient.

The most outstanding shortcoming of this combustion system is that heat loss is big, traces it to its cause: the one, owing to be open burning, only some is absorbed by the bottom of a pan in flame radiation, and all the other all are radiated in the environment.The 2nd, except radiation, flame and flue gas are passed to pot to heat with the form of heat convection, but flue gas leave the pot temperature also very high, be generally about 250 ℃, this part heat is wasted.Cooker commonly used at present is to be made by common metal, there is not any heat-insulation and heat-preservation structure, the heat that absorbs in being subjected to thermal process of cooker is used for heating the food except that part like this, remainder then looses in air by the cooker outer wall, Lang Fei heat also is very big in this way, someone once heated a thermos flask water 12min with the immersion heater of a 1000W, heat the water of same volume then with the electric furnace of same power, the boiled 20min that used of water as a result, why like this many power consumption 67% than the former, reason is that the former heats that the keeping warmth space that is a sealing carries out, heat loss is very little,, and latter's portion of hot amount does not obtain reclaiming and just is lost to environment and has suffered.As seen reclaim heat and can save a lot of energy.

In addition, high power gas kitchen range and oil range utilize air blast to produce wind-force a large amount of air are sent into the combustion zone, improved the phenomenon of combustion zone inner fuel incomplete combustion, temperature raises to some extent, reduced the waste of fuel, and wind-force blows and hits flare and quickened the heat transmission of fire to the bottom of a pan, efficient promotes to some extent, but the wind that air blast produces is many and loose, and the wind that looses in a large number enters the combustion zone and takes away a large amount of heats then again, causes a large amount of heats by blowing away in vain.Do not reach purpose of energy saving like this, waste fuel on the contrary more.

It is to increase some Synergistic and energy-saving devices on common gas-cooker that the Synergistic and energy-saving kitchen range is also arranged, its unique design allows the air that has intense impact power on a small quantity initiatively enter inside, combustion zone, contain a large amount of oxygen in the air, entering of it makes the flame combustion of inside, combustion zone more abundant, improved the phenomenon of common kitchen range incomplete combustion, reduce the discharging of carbon monoxide, improved the air quality in kitchen; The flame temperature that it produced is high and concentrate strong, flame directly acts on the bottom of a pan, no longer edges away, and can see significantly that flame has extremely strong impulsive force to the bottom of a pan, its impulsive force makes fire be greatly improved to the heat transmission in the bottom of a pan, and firing rate is faster; And in the outer shroud of gas that is with one of combustion zone, the invisible shroud of gas in this road is retained in a large amount of heats in the combustion zone, prevents the loss of heat, makes the temperature in the combustion zone higher, and heat energy obtains better utilization.

Chinese invention patent discloses No. 200810059623.0 and discloses the energy-saving stove with thermal radiation arrangement, adopts a tabular heat radiation cover wicking of porous to receive the flame waste heat.But described burner hearth does not form enclosed cavity, therefore, the still very fast outflow burner hearth of flue gas, heat-energy losses is very big.Its cover core is pressed close to the burner hearth wall, and the major part of hot flue gas does not flow through the cover core, and the waste heat that the cover core is collected is few.

Summary of the invention

For solving big, the inefficient shortcoming of heat-energy losses of existing cooking stove, provide the cooking stove that a kind of heat-energy losses is little, the thermal efficiency is high, simple in structure.

Energy-saving cooking, comprise fuel and Air mixing chamber, described mixing chamber is communicated with the spray orifice on the combustion head, described combustion head is arranged in the burner hearth that stove circle, furnace bottom surround, it is characterized in that: described burner hearth has the flue gas outlet, forms flue gas flow channel between described combustion head and the described flue gas outlet; Block the accumulation of heat radiant panel that is provided with porous on the described flue gas flow channel.

Further, described stove circle has the shape that can cooperate, form closed furnace with the pot body, and described flue gas outlet constitutes unique exhanst gas outlet of described closed furnace.

Further, the position of described flue gas outlet is lower than described combustion head, and described accumulation of heat radiant panel is higher than described flue gas outlet, is lower than described combustion head.

Further, the tail gas of drawing through described flue gas outlet carries out heat exchange through heat exchanger and the air that will enter described mixing chamber.

Further, described heat exchanger is arranged in the described stove circle.

Perhaps, described heat exchanger is arranged in the burner hearth.

Perhaps, described heat exchanger is arranged on the outside.

Further, the air inlet port of described heat exchanger is connected with air blast.

Further, described stove circle and furnace bottom are lined with insulation material layer.

Technical conceive of the present invention is: use heat exchanger to reclaim the ember heat, prevent capacity loss, the cold air of heating and combustion gas or fuel oil reaction is used to improve flame temperature and realizes completing combustion.Accumulation of heat radiant panel wherein, the preparation of employing exotic material, can stand 1200～1600 ℃ of Fire Radiations and sweep of gases for a long time, the flue gas that fuel combustion produces is through porous regenerator radiant panel hole, the heat part that flue gas has is absorbed by the porous regenerator radiant panel, temperature was raised to after ceramic wafer was heated, simultaneously heat radiation to being heated vessel, be heated radiant heat that vessel absorb and account for 20～40% of gross energy, even it is higher, behind certain hour, be in poised state,, be heated vessel Yi Bian energy emission given Yi Bian absorb flue gas heat; Flue gas through the accumulation of heat radiant panel can enter heat exchanger, energy is transferred to combustion air, flue gas enters stove circle heat exchanger then, the cold air of the energy exchange in the flue gas in the stove circle, preheating enters the combustion air in the cooking stove, discharge the gas outlet of last flue gas from the stove circle, and at this moment temperature is very low, far below the flue-gas temperature of about 250 ℃ of common stoves.If flue gas enters external heat exchanger, then can directly drain, also can send into the stove circle again and discharge.

Advantage of the present invention is: heat runs off less, thermal efficiency height.
