Abstract

The utility model relates to an energy saving exhausting hood for gas burning ranges. The upper part of a thermal insulation reflection hood is connected with the surface of the stove hood. The outer side of the thermal insulation reflection hood has a hole. The inner side of the thermal insulation reflection hood has holes with different hole diameters. Heat pipes with fins are arranged in the thermal insulation reflection hood and are tightly pressed by a thermal insulation hood cover. A reflection hood is arranged in the center of the lower side of the thermal insulation hood cover. A reflecting fire viewing mirror is arranged below the reflection hood. The surface of the stove hood is provided with a self-regulated stove ring and a chimney outlet. Two long edges at the lower edge of the surface of the stove hood have the heat pipes. One heat pipe end extending out of the surface of the stove hood is connected with a heat exchanger in a water tank. Smoke is discharged into the atmosphere through heat pipes and flues. Radiated heat is recovered and utilized (the combustion rate is improved) through the heat pipes and is reflected to a heater for heating water for domestic life.

Description

Gas kitchen ranges smoke evacuation energy-saving cover

The utility model relates to the smoke evacuation energy-saving cover of a kind of family gas stove.

At present, along with the modernization of urban construction, coal gas is used by the resident in big or middle city, but all gases that coal gas generates in combustion process is polluting surrounding environment, and heat energy loss is very big simultaneously.

The purpose of this utility model is to avoid the problem of above-mentioned existence, design a kind of gas kitchen ranges smoke evacuation energy-saving cover, the cigarette that this smoke evacuation energy-saving cover can absorb in the combustion process is discharged into atmosphere by chimney, can also regain waste heat in addition, part heat radiation is reflexed on the pot that is heated, also can give hot auxiliary air, improve combustion rate, also part heat can be passed to heat exchanger by heat pipe, heat pipe simultaneously the water temperature in the water tank is improved, use for washing.

The purpose of this utility model can realize by following measure: gas kitchen ranges smoke evacuation energy-saving cover, be by the bonnet face, insulation shroud, heat pipe, the insulation reflector, reflector, reflecting flame-observing glass, self-regulated stove circle, heat pipe, water tank, heat exchanger is formed, insulation reflector top is connected with the bonnet face, there is a macropore in the insulation reflector outside, the inboard is distributed with the hole of different apertures, finned heat pipe is being adorned in the inside, compress by insulation shroud, the following central authorities of insulation reflector are reflectors, there is reflecting flame-observing glass in reflector bottom, the bonnet face is provided with self-regulated stove circle and chimney outlet, be heat pipe along long limit below the bonnet face, extend an end of bonnet face at heat pipe and be connected with heat exchanger in the water tank.

Insulation reflector and insulation shroud are circular, are to be formed by light-duty mineral wool or mineral wool compacting.Outer surface coating and metallic paint make it play insulation effect, the thermal losses when reducing burning.Utilize simultaneously the reflex of metal level again, avoid heat radiation as far as possible, the macropore in the insulation reflector outside is near the chimney outlet, be convenient to smoke evacuation, the exhaust smoke hole of inboard different apertures is promptly little near the hole of flue, the hole is big at a distance apart from flue, the be evenly distributed heat pipe of fin of outside is housed in insulation reflector the inside, heat pipe can be cast as together with the fin of outside to be cast, the bonnet face of insulation reflector and top is connected with screw, both sandwich insulation shrouds are so insulation reflector heat pipe and chimney are smoke evacuation systems of the present utility model.

Heat pipe, heat pipe and heat exchanger are the airtight demineralized water syphon circulated systems of cover, be difficult for scaling, obstruction, heat pipe with hot water by the water temperature difference siphon heat exchanger of circulation in heat pipe reaches water tank automatically, in case be that recyclable a part of heat raises the temperature of water in the water tank after the kitchen range heating, water tank is provided with into water and water outlet place, can at will use, so heat pipe, heat pipe, heat exchanger, water tank are residual neat recovering system of the present utility model.

Reflector is the parabola shaped foraminous shield that metal material is made, it is to be adsorbed on kitchen range bottom by magnet, and the reflection that is used for the bottom heat radiation is reclaimed, and also can give heat to air inlet, so to improving the thermal efficiency certain effect is arranged, improves efficiency of heating surface system so insulation reflector and reflector are the utility model.

Reflecting flame-observing glass is used for observing combustion case and is provided with, and it is clear that the intensity of a fire and automatic ignition situation by the hole of reflector.

Self-regulated stove circle is made up of eight lobe semicircles, extension spring, the axis of guide, cover, can regulate size flexible adjustment between φ 200--φ 300 of stove circle automatically, serves as the height benchmark with the size of pot and three supporting-points of kitchen range, and the sealing that it is connected on the bonnet face puts.

Description of drawings:

Fig. 1 is a front view of the present utility model.

Fig. 2 is a vertical view of the present utility model.

The utility model is following advantage compared to existing technology;

1, heating even flame, the thermal efficiency can improve 15%.

2, can recovery waste heat for the hot water of life usefulness.

3, completely cut off flue gas to the pollution of surrounding environment and the electromagnetic pollution in burn hot-tempered sound and the oxidation reaction.

Embodiment of the present utility model such as accompanying drawing:

Gas kitchen ranges smoke evacuation energy-saving cover is made up of wither certainly stove circle (7), heat pipe (8) water tank (9) heat exchanger (10) of bonnet face (1), insulation shroud (2), heat pipe (3), insulation reflector (4), reflector (5) reflecting flame-observing glass (6).Insulation reflector (4) and insulation shroud (3) are in the form of a ring, insulation reflector (4) top is connected with bonnet face (1) and insulation shroud (2) is clipped between the two, insulation shroud (2) and insulation reflector (4) all are that light-duty mineral wool and mineral wool compacting form, surface coating high-temperature coatings and metallic paint, to play insulation, heat loss when reducing burning also utilizes the reflex of metal the heat of loosing to be reflexed to as far as possible on the pot that is heated simultaneously; The outside of insulation reflector (4) has a macropore to aim at flue outlet, there is the hole of a plurality of different apertures the inboard, and the aperture near the chimney exit is little, and it is big away from the aperture in exit, make flame even like this, insulation reflector (4) the inside is that heat pipe (3) heat pipe that has fin can be formed by casting, the following central authorities of insulation reflector (4) are that reflector (5) reflector (5) is the parabola shaped foraminous shield of being made by metal material, it is adsorbed on kitchen range bottom by magnet, reflector (5) bottom is reflecting flame-observing glass (6), the bonnet face is provided with self-regulated stove circle (7) and the chimney outlet is by eight lobe semicircle and extension springs from the stove circle (7) that withers, the axis of guide, cover is formed, can regulate the stove circle automatically, bonnet face bottom is heat pipe (8), the end that heat pipe (8) stretches out bonnet face (1) is connected with the interior heat exchanger (10) of water tank (9).
