Description

Energy-saving household kitchen range

Technical field

The utility model relates to a kind of energy-saving cooking, especially uses solid-fuelled family expenses kitchen range such as firewood, stalk, coal.

Background technology

The utility model relates to a kind of household kitchen range.At present in the vast rural area of China; the kitchen range that remains soil system or brick mix structure that most of rural households generally use; to burn timber; fuel such as reed bar or coal are main; this kitchen range is by combustion flue; the combustion chamber; flue; chimney is formed; combustion flue; the combustion chamber; flue leads directly to; it is combustion-supporting that air enters the combustion chamber by the kitchen range door through combustion flue; like this; the flame that burning produces along flue to chimney direction deflection; heating to cooker is inhomogeneous; the easy spoke of heat seals combustion flue and flue simultaneously; the scope of heat diffusion is bigger; thereby cause the heat energy utilization rate low; Fuel Consumption is big; because fuel mainly is timber; the forest reserves are destroyed serious; be extensive use of liquefied gas cooker at present in the city; but liquefied gas still costs an arm and a leg with respect to rural households; and each natural village comparatively disperses; have inconvenient traffic, this has all caused liquefied gas temporarily also can't popularize rapidly in the rural area, and wood type fuel still is unique selection in most rural households; in this case, thus it is a kind of feasible approach that the consumption that reduces wood type fuel as much as possible reaches the purpose that protects forest resources.

Numerous scientific workers of China and enterprise be just energy-saving and cost-reducing has done a large amount of work, and CN 2427752Y patent just provides a kind of household kitchen range that can move easily that rural households use that is suitable for, and it should have heat energy utilization rate height, advantage that Fuel Consumption is little.This utility model household kitchen range adopts tower structure, by framework, heat-barrier material, refractory brick, combustion flue, the combustion chamber, flue, chimney is formed, the combustion chamber is the semiclosed form that has two openings, an one opening is that charge door is positioned at side direction and makes combustion flue can pass straight through to the combustion chamber facing to combustion flue, another opening is that port is arranged in the top of combustion chamber and stretches into the flue of combustion chamber top, corresponding to also corresponding aperture on the kitchen range panel of port, cooker promptly is placed in this tapping, the flue afterbody is connected to chimney. after adopting such structure, because the combustion chamber is semiclosed form, after combustion flue passes straight through to the combustion chamber, need upwards to pass to flue through port, like this, the heat that burning produces can concentrate on the below of cooker, and the suction force of chimney makes the flame and the flue gas of burning generation flow into flue equably along the port periphery simultaneously, forms annular fiery road, flame and flue gas can evenly distribute under cooker, thereby have improved the heat energy utilization rate.In addition, the prior art has adopted the structure of frame-type, and each part all is integrated into a relatively independent integral body, compact conformation, thereby floor space is little, moves more convenient.

But still there is significant disadvantages in this technology, and after through the bottom of a pan, a large amount of heat energy remaining in the hot flue gas run off with flue, does not obtain utilizing.Secondly, do not accomplish to make the combustion chamber sealing, the port top still is communicated with atmosphere with gap between the shaft by the bottom of a pan, causes a large amount of heat energy losses, though the wind-drawing effect of flue can weaken this once missing.At last, the annular entrance of flue is located near the bottom of a pan place, and under the wind-drawing effect of flue, the hot flue gas of combustion chamber at first can flow into flue, and without the bottom of a pan, has lost the chance at the bottom of the heating kettle, has wasted heat energy.

Summary of the invention

The utility model will solve the existing low shortcoming of the household kitchen range thermal efficiency, provides a kind of thermal efficiency high household kitchen range.

Energy-saving household kitchen range, comprise shaft, burner hearth, be used to set up the stove circle of pot body, form the combustion chamber in the described burner hearth, bottom, described combustion chamber is provided with the kitchen range grate, described combustion chamber is communicated with air inlet duct by described kitchen range grate, described combustion chamber also is communicated with and is used to add the combustion flue of fuel and the flue of getting rid of flue gas, it is characterized in that: block the accumulation of heat radiant panel that is provided with porous between the inlet of described combustion chamber and described flue.

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

Further, the inlet of described flue is positioned at the lower position of described combustion chamber, described accumulation of heat radiant panel be higher than flue inlet, be lower than the bottom of a pan.

Further, the taper anchor ring that described accumulation of heat radiant panel is big up and small down, its top connects the sidewall of burner hearth, and its following frame is at furnace bottom, and described taper anchor ring is in the face of the bottom of a pan.

Further, described burner hearth and furnace bottom are lined with insulation material layer.

Further, tail gas that described flue is drawn is through around the water heater, carries out heat exchange with cold water in the water heater.

Further, the tail gas of drawing through described flue carries out heat exchange through heat exchanger and the cold air that will enter described burner hearth.

Further, described heat exchanger is arranged in the furnace cavity of the below of accumulation of heat radiant panel and flue entrance.

Further, described heat exchanger is connected with air blast.

The utility model utilizes air-flow heat to rise cold rule of falling in use, and flame rushes at the bottom of a pan earlier, turns back to be back to flue entrance through the accumulation of heat radiant panel again, has at first made full use of the heat of flame.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 heat accumulation plate 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 also can be passed to the water heater that is placed on the flue gas flow channel to energy, through can entering heat exchanger after the water heater heat absorption, energy is transferred to combustion air, and flue gas enters flue and discharges by chimney then, and at this moment temperature is very low.

Heating and the cold air that solid fuel reacts help to improve flame temperature and realize completing combustion.

The utility model has the advantages that: heat runs off less, thermal efficiency height.
