Take out by force type gas heater, be that one arranges blower fan on exhaust fume collecting hood top, and utilize the fluid heating that burnt gas discharges by the swabbing action of blower fan.Because the blower fan taking out by force type water heater is arranged in exhaust fume collecting hood, the connected mode thus between exhaust fume collecting hood and heat exchanger is mainly: be enclosed within heat exchanger 02 by exhaust fume collecting hood 01, and fixes with screw 03, as shown in Figure 1.Although existing this exhaust fume collecting hood and heat exchanger package assembly implement comparatively simple, but exhaust fume collecting hood is connected gap, cooperation place with heat exchanger larger, easily cause the problems such as product smoke spillage, noise are large, affect Total Product performance, cause to production and use and have a strong impact on.
Summary of the invention
For the defect existed in prior art, it is simple that the purpose of this utility model is to provide a kind of structure, and good airproof performance, the fume exhaust system that assembly reliability is high, is applicable to take out by force type gas heater.
For reaching above object, the utility model adopts following technical scheme.
A kind of fume exhaust system of flanged turnup structure, comprise: exhaust fume collecting hood and the heat exchanger portion be communicated with exhaust fume collecting hood fill, it is characterized in that, the flange turnup structure of to be normal section be inverted L-shaped that the bottom of exhaust fume collecting hood is provided with outwards downward twice turnover, the end that this flange turnup structure encases heat exchanger portion dress forms hermetically-sealed construction; Described exhaust fume collecting hood is riveted formed by front side board, back side panel, left plate, right plate;
Be respectively equipped with in the bottom of front side board and back side panel the first flanging outwards turned down, the two ends of the first flanging protrude into outside left plate and right plate, and the week of the first flanging is along the second flanging being provided with turnover downwards;
Left plate and right plate are provided with the 3rd flanging of outwards turnover, outside the 3rd flanging, are provided with the Fourth Fold of turnover downwards;
The first flanging that the two ends of the 3rd flanging are different from two is adjacent to, and the second flanging that the two ends of Fourth Fold are different from two is adjacent to.
Further illustrating as such scheme, the two ends of the 3rd flanging form the sealing catch plugged under two the first flangings.
Further illustrating as such scheme, is provided with the carrying flange corresponding with the first flanging and/or the 3rd flanging and heat exchanger upper flange plate in dress end, heat exchanger portion; Described carrying flange and heat exchanger upper flange plate and the first flanging and/or the 3rd flanging are fixedly connected with by screw or weld.
Compared with prior art, the fume exhaust system of a kind of flanged turnup structure that the utility model provides has following beneficial effect:
One, by arrange outwards downward twice turnover in the bottom of exhaust fume collecting hood be normal section be the flange turnup structure of inverted L-shaped, and the end utilizing flange turnup structure to encase heat exchanger portion dress forms hermetically-sealed construction; Without the need to configuring seal in addition, structure is simple, effectively solves exhaust fume collecting hood and the larger problem in gap, dress junction, heat exchanger portion, improving product sealing and assembly reliability; Meanwhile, avoid the leakage of flue gas, and reduce combustion noise, improve security and the comfortableness of water heater use.
Two, by being provided with the carrying flange corresponding with flanging in dress end, heat exchanger portion; What hollow flange plate, flanging, carrying flange were respectively equipped with heat exchanger upper flange plate at least two mutual correspondences is fixedly connected with hole, and being linked and packed that exhaust fume collecting hood and heat exchanger portion are filled is comparatively simple, and production efficiency is high.

Detailed description of the invention
For setting forth essence of the present utility model further, by reference to the accompanying drawings detailed description of the invention of the present utility model is described as follows.
As shown in figs 2-4, a kind of fume exhaust system of flanged turnup structure, comprise: exhaust fume collecting hood 1 and the heat exchanger portion be communicated with exhaust fume collecting hood 1 fill 2, it is characterized in that, the flange turnup structure of outside downward twice turnover to be normal section the be inverted L-shaped in the bottom of exhaust fume collecting hood 1, this flange turnup structure encases the end that heat exchanger portion fills 2 and forms hermetically-sealed construction.
In the present embodiment, preferred exhaust fume collecting hood 1 is riveted by front side board 11, back side panel 12, left plate 13 and right plate 14 and is formed.The two ends being respectively equipped with the first flanging 3, first flanging 3 of outwards turnover in the bottom of front side board 11 and back side panel 12 protrude into outside left plate 11 and right plate 12, and the week of the first flanging 3 is along the second flanging 4 being provided with turnover downwards.Left plate 13 and right plate 14 are provided with the Fourth Fold 6 being provided with turnover downwards outside outside the 3rd flanging the 5, three flanging 5 turned down.After four side plate assemblings, the first flanging 3 that the two ends of the 3rd flanging 5 are different from two is adjacent to, and the second flanging 4 that the two ends of Fourth Fold 6 are different from two is adjacent to, to reach the object of sealing.
