In the kitchen range of natural air inducing burner, except that the air suspended type kitchen range, also have fully-premixed burner (like infrared stove) kitchen range, go up air intake type kitchen range (like partially embedded kitchen range) etc. entirely.Based on the principle of said structure, technology and process, to these other forms of natural air inducing burner type kitchen range, can corresponding adjustment or change integral shown in Figure 1 and protect the relevant portion in heat and the short chimney cavity body structure.For example:
Protect the cavity of heat and short chimney structure for the complete integral of going up air intake kitchen range (like partially embedded kitchen range), the cavity body structure with air suspended type kitchen range shown in Figure 1 is close on the whole.But there is not the secondary wind annular space around the kitchen range core, and the air feed annular space on the kitchen range table top, be the intake adit of secondary wind, also be the intake adit of a wind.
For the kitchen range of the full premixed type burner of the whole combustion airs of injector supply, need not supply secondary wind, the chamber wall of protecting hot cavity can overlap with the wall around the kitchen range.The short chimney structure that this moment, stretched the kitchen range below disappears.The hot cavity of guarantor of kitchen range below can shorten aptly.Mainly acting as of the hot cavity of guarantor of kitchen range below utilizes the kitchen range heat radiation of cavity downwards to come pre-heating fuel and combustion air, the kitchen range below risen protect heat effect simultaneously, avoids the radiation loss of kitchen range below.Mainly acting as of the hot cavity of guarantor of kitchen range top protected heat to combustion flame and the pot device that is heated, and improves flame temperature and pot device heating temperature, improves the thermal efficiency and realizes energy-saving and emission-reduction.
Embodiment 2: as shown in Figure 2, the structure that the integral of Fig. 2 is protected enclosed burning and the heating of hot cavity be nature air inducing burner type kitchen range integrated protect heat and waste heat recovery and natural draught system structure.
Described integral is protected the enclosed burning of hot cavity and the structure of heating is; One is provided with operation and observes door by protecting the short chimney structure that hot chamber wall surrounds on the hot chamber of the guarantor wall at middle part, front side, protect wall upper end, hot chamber and be provided with exhaust fume collecting hood; The smoke evacuation chimney communicates on the exhaust fume collecting hood; Protecting wall lower surface, hot chamber is sealing surface, and kitchen range are positioned at protects wall middle part, hot chamber, and kitchen range side upper end is provided with sealing and protects in the wall of hot chamber and the secondary wind kicker baffle of end spaces on the kitchen range side; In the hot chamber of the guarantor wall of secondary wind kicker baffle lower end is the hot cavity of guarantor of below; On the hot chamber of the guarantor wall of rear side and adjacent two sides, be provided with air preheat cavity 5, be provided with fin in the air preheat cavity, the air air intake vent of the air preheat cavity that communicates is positioned at the outside of exhaust fume collecting hood lower end to be protected on the wall of hot chamber; The air air outlet of air preheat cavity communicates with the hot cavity of the guarantor lower end of below downwards, is provided with the communicate fuel preheating pipeline of kitchen range of port in hot cavity of the guarantor of below and the air preheat cavity.Described fuel preheating pipeline adopts coil pipe, or coiled pipe, or the pipeline of finned tube.
Obviously, on the hot chamber of the guarantor wall of rear side and adjacent two sides, be provided with internal layer and outer chamber wall, form the air preheat cavity between internal layer and the outer chamber wall.
In structure shown in Figure 2, the burning of kitchen range and the heat loss that can avoid heat loss through radiation that conventional kitchen range produce under opening duty, cause the course of work of pot device heating with ambient cold air heat loss through convection and heat conduction and heat radiation.And the combustion function section inner layer cavity wall of cavity and the pot device functional section inner layer cavity wall that mainly is heated also all is set to protect hot chamber wall, and burning is heated with a pot device provides direct guarantor's heat effect, improves a combustion flame and a pot device heating temperature.Therefore, in structure shown in Figure 2, flame obviously improves the heating-up temperature of pot device, and kitchen range obviously reduce with the heat loss of the various heat radiations of pot device simultaneously.Fuel also carries out preheating in the fuel preheating pipeline in being in this heat retainer system.The closed work system that integral is protected heat has improved the thermal efficiency greatly.
The hot cavity of integrated guarantor shown in Figure 2 is to kitchen range both direction stretching, extension up and down.In the ascension effect of higher temperatures (than the low-density) flue gas that burning produces down and protecting under the effect of hot center cavity and the gas density difference in its outboard chambers, integral is protected hot cavity and has been formed a short chimney structure.Air in the outer cavity produces certain draft effect (draft that the exhaust fume collecting hood of kitchen range produces during at wind of injection with the smoke evacuation chimney also produces the draft effect to the air in this skin cavity) to short chimney structure to it in the bottom of central cavity.The draft of short chimney structure has increased a certain amount of secondary wind supply, has improved the completing combustion degree, further improves the kitchen range thermal efficiency.
In structure shown in Figure 2, a part of secondary wind is through burner (or claiming kitchen range, kitchen range core) annular space supply all around, and a part of in addition secondary wind provides through the secondary wind annular space on the kitchen range table top, under the secondary wind kicker baffle.On two sides of kitchen range and opposite, the air preheat cavity of protecting hot outer wall can be set.In the air preheat cavity fin can be set, improve heat exchange efficiency.Because the heat transfer coefficient of gas is lower, the dividing wall type gas converting heat needs bigger heat transfer area.The air preheat cavity can upwards be provided with suitable height to obtain enough heat exchange areas in both sides and three limits, opposite, reasonably reclaims the waste heat of tail gas.The pass is closed the positive operation of kitchen range and is observed door 4, can prevent that cold air from influencing using waste heat from tail gas and reclaiming.

On above-mentioned short chimney structure (containing the air preheat cavity), the smoke evacuation chimney that directly connects exhaust fume collecting hood and be communicated with exhaust fume collecting hood.This exhaust fume collecting hood becomes discharge flue with this smoke evacuation chimney.Because flue gas has certain temperature and heat with culinary art tail gas self, the oil smoke tail gas of heat produces stack effect in this discharge flue.This stack effect produces the draft of smoke evacuation, realizes natural draught system.This discharge flue can directly lead to independently smoke discharging structure of outdoor formation, also can be communicated with the flue of the central exhaust of building.This discharge flue is set to be incubated passage, can improve the draft of smoke evacuation.
With power-saving technology shown in Figure 2 and principle, adopt the commodity kitchen range of selling on the market to carry out practical measurement and show, boiled time of normal-temperature water of amount has equally been shortened about 1/3, and natural draught system, energy-conservation more remarkable with emission reduction effect.
For other forms of natural air inducing burner type kitchen range; Comprise fully-premixed burner (like infrared stove) kitchen range, go up air intake type kitchen range etc. entirely; According to the principle of said structure, technology and process, can be on the basis of Fig. 2 corresponding adjustment or change integral and protect the relevant portion in heat and the waste heat recovery cavity body structure.For example:
For the full integral guarantor heat of air intake (like partially embedded kitchen range) and the cavity body structure of air intake type suitable for reading waste heat recovery gone up, the structure with shown in Figure 2 is close on the whole.But there is not the secondary wind annular space around the kitchen range core, and the air feed annular space on the kitchen range table top, be the intake adit of secondary wind, also be the intake adit of a wind.
The inner layer cavity wall of protecting hot cavity can overlap with the wall around the kitchen range.This moment, cavity stretched the draft effect that does not produce short chimney structure to the kitchen range below.The draft of supply combustion air is produced by the smoke evacuation chimney fully.Mainly acting as of the hot cavity of guarantor of kitchen range below utilizes the kitchen range heat radiation of cavity downwards to come pre-heating fuel and combustion air, the kitchen range below risen protect heat effect simultaneously, avoids the radiation loss of kitchen range below.Mainly acting as of the hot cavity of guarantor of kitchen range top protected heat to combustion flame and the pot device that is heated, and improves flame temperature and pot device heating temperature, improves the thermal efficiency and realizes energy-saving and emission-reduction.
Embodiment 3: as shown in Figure 3, the structure that the integral of Fig. 3 is protected enclosed burning and the heating of hot cavity be burner type kitchen range integrated of exogenous power air feed protect heat and waste heat recovery and natural draught system structure.
