Description

Energy-saving stove with dragon wind

[ technical field ] A method for producing a semiconductor device

The invention relates to a dragon wind energy-saving cooking stove.

[ background of the invention ]

With the development of economy, the energy consumption is more and more, the price is higher and more, the environment is worsened gradually, and the global average temperature is gradually increased. The government advocates the adoption of new technology to save energy, reduce emission, and maintain a long-term and sustainable ideal environment. Three meals a day are rare, and although an electromagnetic oven, a microwave oven, an electric cooker and the like can cook rice by boiling water, high-temperature cooking and open fire stir-frying are still the mainstream trends. According to the publication of an authoritative structure, the heat efficiency of the existing gas stove on the market is only 40% -55%, so that the development of the high-efficiency energy-saving stove has a wide prospect.

The current situation and the defects of the current pot stove technical development:

1. the technical advantages and disadvantages of the firewood stove and the gas stove are compared:

from the cooking by hanging a pot (ceramic plate) to cooking by burying the pot, the process from fussy, smoking, burning and consuming firewood to the process from easy smoking, sealing, firewood saving and gas saving is carried out from the common cooking bench to the firewood saving stove and from the common gas stove to various energy saving gas stoves. Firewood is burnt by the firewood stove, the firewood is heavy, time and smoke are more dust, the gas-saving stove is burnt by gas, the firewood stove is easy and convenient, less smoke is less, dust is less, but the firewood-saving stove is superior to the gas-saving stove in the following aspects: a. it has no electricity to smoke, and reduces harmful gas and dust in the kitchen; b. it is sealed and burnt, wind-proof, energy-storing and heat-insulating, and reduces convection radiation; c. the pot prolongs the creeping distance of the flame from the bottom of the pot to the edge of the pot, and effectively utilizes heat energy.

2. Fin energy-saving technology

Some pans on the market are welded with heat absorbing sheets with the height of 2-5cm radiating to the periphery at the bottom, some pans are additionally provided with heat locking rings at the edge of the pan, the heat absorbing sheets increase the heating area of the pan bottom by 4-5 times, and the pans are combusted in a closed manner, so that the heat efficiency is greatly improved, the pans can be used for boiling water and soup, the open fire cannot be used for stir-frying, fins at the pan bottom are easy to damage and deform due to dry combustion and touch damage, the weight of the pan is increased, and the pans are not seen in the market. Some pot with sharp bottom has also die-cast fin, but can't die-cast the heat locking ring, realize the closed combustion, the energy-conserving effect is not too obvious.

3. Energy-saving ring for cooking range

The gas stove simulates a traditional cooking bench to enable flame of the gas stove to burn in a relatively closed environment, can prevent wind, preserve heat, store energy and reduce convection radiation, and has obvious energy saving compared with the gas stove without an energy-saving ring. Because the pan, the stove, the energy-saving ring and the fire plate are not produced in one house, the distance between the pan and the fire plate can not be adjusted generally, the gas is wasted when the distance between the pan and the fire plate is too large, and the black pan is burnt when the distance is too small, so that the combustion is insufficient. In addition, the upper end of the energy-saving ring can not be sealed, and through holes for discharging various smoke and fire are needed to be arranged, so that the hidden danger of flameout during overflowing is caused.

4. Rotary fire technique

The flame of the gas stove is divided into direct fire and oblique fire. The direct fire hole is circular, is vertical to the plane of the fire plate, and the flame directly rushes to the bottom of the pan, so that the fire is strong, the flame is smooth, and the pan is suitable for the pan. The flame is obliquely rushed to the bottom of the pot, the flame is integrally seen to be in a rising cyclone shape and surrounds the center of the pot bottom, the oblique fire is suitable for any pot shape, the contact area of the flame and the pot bottom is larger, and the energy is saved compared with direct fire. The straight line between the two points is shortest, the oblique fire is the hypotenuse of the right triangle, the distance for the flame to convey heat energy to the pot bottom is relatively long, and the heat loss is more. If the flame is directly projected to the pot bottom, the rising whirlwind-shaped flame surrounds the pot bottom and then rotates to rise towards the pot edge, so that the length of the flame and the pot bottom can be increased, the length of the flame and the pot edge can be compensated, and the creeping distance of the flame from the pot bottom to the pot edge can be prolonged.

5. Waste heat utilization technology

There have been two preheating utilization techniques in the prior art. Firstly, high-temperature steam, oil smoke and high-temperature waste gas generated by a gas stove for cooking are absorbed by an exhaust fan and then used as combustion-supporting gas, and secondly, a basin-shaped water pipe is enclosed around a fire pan to heat water. Although the temperature of the combustion-supporting gas is high, most of the oxygen is exhausted, and the combustion-supporting gas is not suitable for serving as the combustion-supporting gas due to the existence of water vapor. The latter is too close to the bottom of the pot, so it is vulnerable to snaking with the bottom of the pot.

6. Atmospheric combustion defect of gas stove

The gas stove on the market at present is an atmospheric gas stove, namely high-speed high-energy gas is sprayed out from a nozzle to enter a contraction pipe of an ejector, meanwhile, the static air around the gas is driven to enter a mixing pipe together for mixing, then enters a diffusion pipe for speed reduction and pressure reduction, and finally reaches a fire hole of a fire plate to ignite and fire. The ideal combustion state is that the more the gas is, the more the combustion air is needed, the less the gas is, the less the combustion air is needed, and the quantity of the combustion air entering the mixing pipe is determined by the air door, the size of the air door is generally determined by adjusting the flame to be pure blue by the medium fire (namely, the optimal combustion state), namely, the air door is not adjusted any more in the actual operation of the large fire and the small fire, so that the relatively excess combustion air of the small fire is formed, and the heat energy is taken away; and the air for combustion supporting by big fire is relatively insufficient, the flame turns red, the gas is not fully combusted, and the gas is wasted.

From firewood-saving stove to gas-saving stove, people continuously develop towards the direction of saving firewood, saving gas, saving energy, being efficient, clean and environment-friendly. The various technologies have advantages and disadvantages, whether the technologies can be skillfully combined together or not can avoid the defects and exert the advantages, and a brand-new energy-saving cooking stove is designed. With respect to this situation and vision, the present invention has been made based on this situation through many years of intense research and development.

And the lower part of the fire plate 7 is blown through the bell mouth 841 for air supply, so that combustion-supporting air can be supplemented, and simultaneously, tempering can be prevented.

The fan 81 is provided with multi-gear wind power adjustment and is controlled by the firepower adjusting switch 87 in a linkage mode, the speed adjusting switch of the fan 81 and the gas firepower adjusting switch are synchronously matched together, the stop of the fan corresponds to gas flameout, when the firepower adjusting switch 87 is started, the fan is turned on while the gas is turned on, the wind power of the fan is increased while the firepower of the fire plate is increased, the wind power of the fan is decreased while the firepower of the fire plate is decreased, so that the size of air supply is synchronously adjusted according to the size of gas supply, and the optimal combustion state is achieved.

According to the energy-saving stove with the dragon wind, a small part of air and fuel gas are mixed in the ejector 86 along with synchronous change of firepower, and a large part of air rushes from the bottom of the fire plate 7, so that mixed gas of the air and the fuel gas reaches a better combustion proportion when the mixed gas is combusted on the surface of the fire plate, the problem that combustion-supporting air is insufficient relatively in closed combustion and atmospheric combustion is solved, and the tempering problem of the blast injection technology is also solved.

The phenomenon of backfire and relatively insufficient combustion-supporting air in closed combustion can be avoided by the upward blowing force of the fan 81 from the bell-mouth 841 and the suction force during smoking.
