Description

Internal-burning type multifunctional stove

Technical field:

The present invention relates to a kind of home-use internal-burning type multifunctional stove system with energy-conservation and environment-friendly function.

Background technology:

At present, in most family, maximum daily pollution is present within the kitchen.Even if use by various combustion gas that we are referred to as clear energy sources as the energy, waste gas and some pernicious gases after a large amount of burnings are being distributed in also still in use peripherad space.Secondly, various kitchen range discharging waste gas after burning in air when, also are dispersed into a large amount of heats space on every side under present this open environment for use.So kitchen range that present family kitchen adopts and using method exist serious contaminated environment and the problem that wastes energy.On the angle of safety usefulness gas, in a single day the situation of gas leakage takes place in present family kitchen, the combustion gas of leaking tends to disperse around come, though there are some range hoods to have imflammable gas concentration over-standard warning function, but the combustion gas in the kitchen has at this moment often accumulated to certain degree, we each relevant kitchen utilities manufacturing enterprise and relevant security department at this moment tell we the measure that can take be basically: turn off source of the gas, mustn't device for switching, open the door and window allowing air flow.In case and people do not have to find timely the leakage of combustion gas, then tend to cause very serious consequence.And this imflammable gas sniffer is owing to being exposed under the environment of high oil smoke for a long time, so As time goes on its detectivity can progressively descend.

Summary of the invention:

The objective of the invention is to provide a kind of adopts combustion gas sealing burning form, burning back waste gas and leakage can be in time and can control discharging, that calory burning can make full use of, as to have outstanding security performance, energy-efficient performance, environmental-protecting performance home-use internal-burning type multifunctional stove system.The deficiency that said present family kitchen exists when being engaged in family's cooking operation above the solution that this system can be outstanding.

The object of the present invention is achieved like this: this internal-burning type multifunctional stove system is by gas-cooker, the closed burner hearth of thermal-insulating type, special type be heated cooker (pressure cooker, steamer, kettle etc.), toxic emission and waste heat recovery and utilize system etc. to form.The burner hearth block that an employing has the material manufacturing of insulation and heat resistance is set around the duration and degree of heating of gas kitchen ranges.This block is used in combination with corresponding cooker, forms the closed burner hearth of thermal-insulating type between kitchen range duration and degree of heating and cooker.This block has following four functions: promptly can the duration and degree of heating of gas kitchen ranges be sealed accordingly; Can stop again that heat is peripherad to be distributed; Can also carry out pipe sealing row for waste gas after burning and be provided condition; For the various pots on the kitchen range, kettle etc. provide a support, make itself and duration and degree of heating keep the heating distance an of the best simultaneously.This block is used with corresponding cooker, around the duration and degree of heating of kitchen range and above form the environment of a complete closed, like this, the heat that the kitchen range duration and degree of heating is sent is high efficiency to be transmitted on the various cookers that are positioned at duration and degree of heating top.We know that the propagation of heat has these three kinds of modes of convection current, conduction and radiation.Because the material manufacturing with insulation and heat resistance is adopted in this block, so conducting towards periphery with the heat of radiation, it compares with the kitchen range of the open combustion system of present employing, can significantly reduce, and toxic emission mode after the burning of enclosed burning that it adopts and channelization, can be by a windshield device that is arranged on the vent pathway, the exhaust air rate of control vent pathway, make its emissions status that is in a best, thereby can significantly reduce the unconfined thermal loss that flows and bring of gas after the burning.Because more than, make us under the duration and degree of heating situation that employing compares less, to obtain the higher temperature output that compares to various cookers on the kitchen range, significantly improve the efficiency of combustion of gas kitchen ranges.

Because the mode of heating of this relative closure that this kitchen range in use adopt, make us can accomplish very easily waste gas after burning is concentrated and the control discharging, so promptly can significantly eliminate of the pollution of burning back waste gas, can further reclaim and utilize the contained heat of waste gas again surrounding environment.We know: the hot gas of this burning itself has a kinetic energy that makes progress, in this invention, appropriate location, top in the burner hearth block, a toxic emission hole is set, because general gas kitchen ranges all adopts the configuration of dual-range-head, and the tapping equipment of these kitchen range is that two kitchen ranges are shared, change windscreen so be provided with a discharging at this discharge orifice place, the function of this windscreen is: promptly can select some kitchen ranges to be in emissions status, also can make two kitchen ranges be in emissions status simultaneously.This discharge orifice is connected with a same pipeline that adopts insulation and heat proof material to make, the other end of this pipeline can be connected with a heat exchanger, and this interchanger is made of heat radiation bag, attemperater, tap water supply device, hot water water supply installation, discharge duct etc.Its course of work is: the hot gas after the burning enters heat radiation bag in the heat exchanger along burner hearth block and discharge duct, in heat exchanger, the outside of heat radiation bag is a water tank, this water tank adopts metal or plastic material manufacturing, have tap water supply device and hot water water supply valve, the outermost of water tank is one deck insulation material.After the waste gas that contains heat after the burning flows out from heat exchanger, temperature will significantly descend, at this moment the exhaust outlet of discharge duct is guided to the appropriate location of kitchen exhaust device (range hood or ventilating fan), utilize the suction and the draft of this air exhausting device, waste gas after burning is discharged to outdoor.The kinetic energy that this device also can utilize fuel gas buring to produce is heated up water or steamed rice etc. does not produce under the situation of oil smoke or steam at kitchen range, waste gas after burning is directly discharged outdoor, and need not open electronic exhaust apparatus, thereby further cut down the consumption of energy.

On the appropriate location in discharge duct, burnable gas sensor in the pipeline is set, burnable gas sensor outside is set in the appropriate position of range hood or ventilating fan.

When in a single day the gas leakage fault takes place in kitchen range, the combustion gas meeting is flowed to outdoor along the device of this sealing, also be not able to do in time under the situation that kitchen and environment on every side thereof are dispersed in the combustion gas of leaking like this, the interior imflammable gas sniffer that is arranged in the discharge duct will give the alarm, because the gas emission system of kitchen air exhausting device and these kitchen range is relative closures, so at this moment allow this imflammable gas sniffer when reporting to the police, range hood is opened, discharge the environment of imflammable gas by this sealing outdoor and in our present gas safe operation notice (country is to the working specification of the present neither one strictness of the safe handling of domestic gas), requirement at this time is: find gas leakage, mustn't open on-the-spot and electrical appliance on every side.When the leakage rate of imflammable gas very big and outside burnable gas sensor when at first reporting to the police or reporting to the police subsequently along with the warning of interior burnable gas sensor, outer imflammable gas sniffer should be able to cut out scavenger fan, prevents the generation of combustion gas deflagration accident having.

Because the narrower and small and various flue gas concentration content in space between kitchen range and the kitchen exhaust device (range hood or ventilating fan) are higher, exist poor working environment, and be in the problem that cooker on the kitchen range is fought for usage space so be arranged on the heat exchanger of this position.For addressing this problem, this invention has been taked heat exchanger and gas kitchen ranges or heat exchanger and design of range hood one and the technical measures of making.In the technical measures of heat exchanger and design of gas kitchen ranges one and manufacturing, utilize the interior clearance spaces of gas kitchen ranges casing and the peripheral space of the closed burner hearth of thermal-insulating type, heat exchanger is set, like this can be so that the overall structure of this internal-burning type multifunctional stove becomes very compact.In the technical measures of heat exchanger and design of range hood one and manufacturing, heat exchanger is arranged within the vacant casing of range hood.

When waste gas after burning need be discharged when indoor by range hood, adopt following two kinds of discharge modes: the appropriate location that exhaust pipe mouth is arranged on range hood or ventilating fan air inlet place, the suction that utilizes fan work to produce is discharged waste gas after burning outdoor.The shortcoming of this method is to rely on the work of range hood waste gas could be discharged outdoor.Another kind method is the wind output channel place that exhaust pipe mouth is arranged on range hood, the negative pressure of utilizing air in wind output channel, to produce during flow at high speed, to be in the waste gas after burning sucking-off in the exhaust emission pipe, discharge outdoor with the air that scavenger fan is discharged.This exhaust apparatus and method for exhausting can accomplish that range hood is not worked when not having other waste gas (oil smoke, steam) discharging, and the kinetic energy that heat energy produced by burning back waste gas self by gas exhaust piping, flows automatically to outdoor.
