Background technology
At present, owing to reasons such as the anxiety of the energy and combustion gas rises in price, people give very big concern to fuel gas energy-saving.Aspect energy saver that existing gas furnace matches, a lot of energy-conserving products appear, and the structure that has is complicated; The needs that have unload the burning jamb of original stove and accessory could install energy saver, and such one needs the professional to make house calls, and two need to put on record through competent departments concerned's approval, directly influence the application and the popularization of its energy-conserving product; The energy-saving effect that has is undesirable; What have is that cost is obtained energy-saving effect with obviously weakening of firepower then.Comparatively speaking, at present gas furnace heat-collected energy-saving appliance has that it is simple in structure, energy-saving effect is than remarkable advantages.But known gas furnace heat-collected energy-saving appliance still has the following disadvantages: one, because this energy-saving appliance is generally the concave shaped arc dish that centre bore is arranged that is pressed into by the monometallic thin plate, so, heat conduction and heat loss through radiation are too fast, heat build-up be energy-saving effect undesirable (though if any statement 40% fractional energy savings is arranged, generally be no more than 20% through actual detected); Simultaneously, stove and accessory table top temperature is too high, makes the serious scaling loss of table top protective layer, table top generation gross distortion, high temperature damage gas seal, and then cause the security incident hidden danger of gas leakage, also make gross distortion of energy-saving appliance own and oxidation corrosion, the service life of energy-saving appliance itself and stove and accessory is shorter; Also exist in to locate on the stove and accessory and forbidden, easily move the position, thereby produce the problem of fire partially; Also have, because the structural limitation of this energy-saving appliance is unfavorable for the abundant completing combustion of combustion gas, so, pernicious gas severe overweight such as its carbon monoxide in combustion process.
The utility model content
The technical problems to be solved in the utility model is, overcome the defective of above prior art, provide that a kind of intensity of fire is good, structure and install simple, energy-saving effect is desirable, low, the no potential safety hazard of stove and accessory table top temperature, itself do not have that distortion, location are accurate, content of harmful gas meets national standard in the life-span length, combustion process gas furnace heat-collected energy-saving appliance.
Technical solution of the present utility model is, a kind of gas furnace heat-collected energy-saving appliance with following structure is provided, comprise centre bore, the insulation layer that the integral body that it is formed by inner bag and shell is pressed from both sides in the middle of it is formed, described inner bag is a concave shaped arc plate, described shell has the positioning boss that matches with combustion gas tool table top fire door, is fixed with many tilting or spiral water conservancy diversion convex tendons on the arc surface of described inner bag.
As improvement, be fixed with many radially cooker supporting convex tendons on the arc surface of described inner bag central hole.
After adopting above structure, the utility model compared with prior art has the following advantages:
Owing to adopt sandwich, be filled with certain thickness heat preserving and insulating material in the interlayer, significantly increased heat transmission resistance, significantly reduced conduction heat, radiant heat from flame flow, reduced convection heat losses with the outside air layer.And significantly improved fire box temperature, and be convenient to that combustion gas is at high temperature swifter and more violent, completing combustion, and directly improved the heat exchange efficiency with cooker, make energy-saving effect remarkable.
Fuisw rib can reduce photothermal loss to the radiant heat of stove internal reflection thermal-flame part.Guiding gutter between the fuisw rib can produce the flame cyclone, prolong flame flow reaches the cooker bottom surface in stove flowing time, can directly improve heat exchange efficiency, the narrow slit that energy-saving appliance and cooker bottom surface form, can produce " airflow stack effect ", help flowing of combustion-gas flow, combustion process can be carried out more smoothly.
In sum, this gas furnace heat-collected energy-saving appliance cooker heating surface area is big, is heated evenly, and windproof, firepower is violent, and promptly intensity of fire is than common stove and accessory height; Install simple, easy to operate; Stove and accessory table top temperature low (being no more than 70 ℃), gas seal can not damage, no potential safety hazard; Resistance to deformation rigidity is big, and the thermal deformation resistant ability is strong, and is reliable and stable at the stove and accessory upper support; Energy-saving appliance itself and stove and accessory long service life; Energy-saving effect very good (reaching as high as 44%) through the actual detected fractional energy savings, environmental protection safe in utilization, not having the pernicious gas that exceeds standard is that content of harmful gas meets national standard in the combustion process.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
In Fig. 1, Fig. 2, this gas furnace heat-collected energy-saving appliance comprises centre bore 7, and the insulation layer 2 that the integral body that it is formed by inner bag 1 and shell 3 is pressed from both sides in the middle of it is formed (there is the centre bore 7 for flame combustion at its center), and the plan view shape of its inner bag 1 is an annular.Described inner bag 1 is a concave shaped arc plate, and described shell 3 has the positioning boss that matches with combustion gas tool table top fire door, and described positioning boss can be circular or square according to the shape of gas furnace table top fire door.Be fixed with many tilting or spiral water conservancy diversion convex tendons 6 on the arc surface of described inner bag 1.Water conservancy diversion convex tendon 6 can have been held concurrently and supported the effect of cooker.Also can be fixed with many radially cooker supporting convex tendons 5 on the arc surface at described inner bag 1 centre bore 7 places.Mouth and the cover plate 4 that enters for heat preserving and insulating material in the interlayer arranged in shell 3 bottoms.
Described inner bag 1 and water conservancy diversion convex tendon 6 can be formed by the steel plate compacting with shell 3, are connected into integral body by punching press or welding again, and the Weld-supporting convex tendon 5 again.Described insulation layer 2 can adopt material fillings such as perlite.
