Description
Technical field
The present invention relates to a kind of cooking stove, be specifically related to a kind of cooking stove utilizing burner exhaust heat temperature difference self power generation to drive air feed.
Background technology
Existing conventional energy resource oil, natural gas and coal saving amount are limited, and people, while the urgent energy finding novel green replaces conventional fossil fuel, are also actively studying, carrying out power-saving technology.Semiconductor temperature differential generating has been supplied in the fields such as military affairs, medical treatment, scientific research, communication, navigation, power and commercial production, but is applied in terms of daily life UTILIZATION OF VESIDUAL HEAT IN still the most rare.In terms of improving coal stove efficiency of combustion, Patent No. " 201410218770.3 ", the patent documentation of entitled " a kind of self generating and self-ventilation combustion stove " gives a kind of air-supply technical scheme, but need heat conduction in burner hearth, though improve the efficiency of combustion of coal or biomass to a certain extent, but also consuming the heat that fuel combustion produces, overall efficiency is the highest, it is more beneficial for improving efficiency of combustion by the shape or chamber structure changing fuel.At present, China's gas-cooker efficiency of energy utilization typically only has about 50-70%, there is the problem that insufficient waste heat inefficient, a large amount of that burns fails to utilize；The cooking stove of domestic there is also fiery hypodynamic problem simultaneously, causes and cannot make as the exquisite good to eat dish in hotel.
Summary of the invention
Heat in loss burner hearth.Air supply device includes blower fan, air inlet, air outlet, and blower fan can be selected for all types of blower fan, such as axial-flow type, centrifugal and tubular, even bladeless fan etc.；Air supply device electrically connects with thermo-electric generation unit, the outfan of thermo-electric generation unit is connected with the input of air supply device and forms loop, electric wire for electrical connection is easily bent or contracts and prolongs, therefore air supply device has well adapting to property in terms of installation site, and air supply device can be installed completely according to the actual requirements, as long as air inlet is not obstructed, air outlet connects with the air inlet of cooking stove, may be installed on body of heater, it is possible to device is at bottom of furnace body, it might even be possible to be arranged on furnace interior.
Further, described temperature difference electricity generation device also includes that rack-mount fin, described fin are provided with gas channel and connect with the air inlet of air supply device, and the bottom of described fin is connected with the cold end of thermo-electric generation unit.Fin can increase heat exchange area, described gas channel connects with the air inlet of air supply device, air-flow flows through fin strip to be walked the heat distributed on fin and becomes thermal current, because the negative pressure that air supply device air inlet is formed, it is combustion-supporting that thermal current is finally admitted to cooking stove along gas channel entrance air supply device.
Further, described temperature difference electricity generation device also includes that rack-mount conducting strip, the bottom of described conducting strip are connected with the hot junction of thermo-electric generation unit.Conducting strip bottom is connected with the hot junction of thermo-electric generation unit, and the other end of conducting strip, to burner hearth, absorbs the waste heat of cooking stove.
Further, described fin being also equipped with heat pipe, the heat conduction direction of described heat pipe is identical with the heat transfer direction of fin.Heat is to transmit toward low temperature from high temperature, and the temperature difference produces heat conduction, and the heat conduction direction that heat pipe is installed also is toward low-temperature end from temperature end, consistent with fin heat direction of transfer.
Further, described conducting strip being also equipped with heat pipe, the heat conduction direction of described heat pipe is identical with the heat transfer direction of conducting strip.Heat is to transmit toward low temperature from high temperature, and the temperature difference produces heat conduction, and the heat conduction direction that heat pipe is installed also is toward low-temperature end from temperature end, consistent with conducting strip heat direction of transfer.
Further, also including electric storage device, described electric storage device and thermo-electric generation unit, air supply device are in parallel, and are provided with diode on the outfan of generator unit or the loop of input.Waste heat at cooking stove is excessive when causing generating too much, and unnecessary electrical power storage can be got up by electric storage device, increases the electric current of air supply device in the case of the less generated energy of waste heat is less.The characteristic of the unidirectional energising of diode can stop the electric current of electric storage device to reflux to thermo-electric generation unit.
Further, also include a thermal switch, connect with electric storage device.The thermal switch connection when cooking stove burns, when cooking stove extinguishes, thermal switch disconnects.When cooking stove is in use state, the temperature of burner burning makes the temperature of cooking stove higher than the temperature of external environment, and thermal switch is in connected state；But when cooking stove extinguishes, the temperature of cooking stove is gradually identical with ambient temperature, and thermal switch will disconnect, and prevents the electric current of electric storage device from still powering to air supply device when cooking stove extinguishes.
Compared with prior art, the present invention utilizes burner exhaust heat temperature difference self power generation to drive the technical scheme of air feed, utilizes the waste heat of cooking stove to be converted into electrical energy drive air supply device for cooking stove air feed, cooking stove can play increase firepower and combustion-supporting beneficial effect.
