Detailed description of the invention
Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, the gas heater that the utility model embodiment relates to comprise set gradually from the bottom to top burner 1, combustion chamber 2, heat exchanger 3 and blower fan 4, wherein: the heat that burner 1 produces is passed to heat exchanger 3 by combustion chamber 2; Blower fan 4 is communicated with combustion chamber 2 internal cavity, and under the draft effect of air exhauster 4, the heat in combustion chamber 2 can be pumped to heat exchanger 3, with the cold water in reheat heat exchanger 3, realizes the function that water heater produces hot water.
In order to reduce combustion chamber 2 surface temperature of gas heater, the present embodiment adopts with lower combustion chamber 2 structure.
As Figure 2-Figure 5, the utility model preferred embodiment proposes a kind of combustion chamber 2 structure of gas heater, comprise: combustion chamber housing 21 and the insulating frame 22 be arranged in described combustion chamber housing 21, between the outer surface of described insulating frame 22 and the inner surface of described combustion chamber housing 21, there is gap 23, described insulating frame 22 comprises the heat insulation side plate 221 surrounded along described combustion chamber housing 21 surrounding, when water heater working, the heat part produced in combustion chamber 2 is transparent in the gap 23 between heat insulation side plate 221 and combustion chamber housing 21 inner surface by heat insulation side plate 221.
In the present embodiment, the gap 23 between above-mentioned heat insulation side plate 221 and combustion chamber housing 21 inner surface, the above-below direction along described combustion chamber 2 extends, and the lower end in described gap 23 is communicated with the space outerpace of described combustion chamber housing 21.This gap 23 is not only communicated with extraneous air, but also be communicated with the suction opeing of blower fan 4, under the draft effect of blower fan 4, convection current is formed between the inner surface and the inner surface of insulating frame 22 of combustion chamber housing 21, by blower fan 4, the heat in described gap 23 is pumped to described heat exchanger 3, namely the heat in the heat in combustion chamber 2 and described gap 23 can be pumped to heat exchanger 3 by blower fan 4 simultaneously, thus, not only can reduce the surface temperature of combustion chamber 2, the thermal efficiency of gas heater can be improved again simultaneously.
Particularly, described insulating frame 22 comprises four the heat insulation side plates 221 surrounded along combustion chamber housing 21 surrounding, and the lower edge position of described combustion chamber housing 21 is provided with the draw-in groove installing described heat insulation side plate 221.
This draw-in groove can in the lower edge position of combustion chamber housing 21, surrounding along combustion chamber housing 21 is uniformly distributed, and such as in the lower edge position of each sidewall of combustion chamber housing 21, can arrange one or more draw-in groove respectively, wherein, the length of draw-in groove can not limit.
As a kind of embodiment, described draw-in groove is made up of the sidewall of described combustion chamber housing 21 correspondence, the first side plate 212 be oppositely arranged with described sidewall and the base plate that is connected described sidewall and described first side plate 212.
After described heat insulation side plate 221 is installed to corresponding described draw-in groove, by applied external force, described first side plate 212 can be made to bend to the one side of heat insulation side plate 221, thus compress described heat insulation side plate 221.
Further, can also in draw-in groove, in combustion chamber housing 21 sidewall with between described first side plate 212, relative described first side plate 212 arranges the second side plate, after described heat insulation side plate 221 is installed to corresponding described draw-in groove, pass through applied external force, the second side plate can be made to bend to the another side of heat insulation side plate 221, further compress heat insulation side plate 221 by the second side plate.
Further, in order to make, each heat insulation side plate 221 is fastening to be arranged in above-mentioned draw-in groove, as a kind of embodiment, can arrange the projection 213 pushing against described heat insulation side plate 221 on the inner surface of described combustion chamber housing 21.Like this, hold effect on the one hand by draw-in groove, on the other hand, by protruding 213 push against effect, heat insulation side plate 221 can be fixedly mounted between the projection 213 of burner 1 housing and draw-in groove first side plate 212.
Preferably, above-mentioned protruding 213 can be uniformly distributed on the inner surface of combustion chamber housing 21, and its concrete distribution rule can be such as, arranges multiple protruding 213 respectively in the top and the bottom of the inner surface of combustion chamber housing 21.
In addition, the present embodiment does not do concrete restriction to the shape of protruding 213, can be various shape, as long as can realize the effect pushing against heat insulation side plate 221.
In the present embodiment, the bottom of described combustion chamber housing 21 is provided with the brace 211 connecting burner 1, for being fixedly connected with combustion chamber housing 21 by burner 1.Described gap 23 is positioned at the outside of described brace 211.
When gas water heater working, insulating frame 22 combustion that burner 1 surrounds at heat insulation side plate 221, cold water in high-temperature flue gas (high-temperature flue-gas can reach about the 1000 DEG C) reheat heat exchanger 3 produced, some heat overflows (surface temperature of heat insulation side plate 221 can reach about 200 DEG C) through heat insulation side plate 221 simultaneously.Now because blower fan 4 is also in work, blower fan 4 produces draft, air enters from outside, owing to having gap 23 between combustion chamber 2 inner surface and heat insulation side plate 221, so formation convection current, the heat given out through thermal insulation board is taken away, be used for reheat heat exchanger 3, so both reduce the surface temperature (combustion chamber 2 surface temperature can be reduced to less than 100 DEG C) of combustion chamber 2, turn improve the thermal efficiency of gas heater simultaneously.
The present embodiment passes through such scheme, utilize the exhausting of Forced discharge fan 4, convection current is formed between combustion chamber 2 inner surface and thermal insulation board, the heat given out through thermal insulation board is taken away, be used for reheat heat exchanger 3, so both reduce combustion chamber 2 surface temperature, turn improve the thermal efficiency of gas heater simultaneously.
Above are only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description and accompanying drawing content to do equivalent structure or flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
