Detailed description of the invention
Describe embodiments of the invention below in detail, the example of described embodiment is shown in the drawings, and in each figure, identical label represents identical part. Also it will be appreciated that, term " downwards ", " upwards " indicated position relationship are based on position relationship shown in the drawings, and it is the present invention and simplified characterization for convenience of description only, can not be interpreted as limitation of the present invention.
As shown in Figure 1 and Figure 2, the fume extractor 100 that is applicable to gas heater comprises cover body 01, smoke collecting chamber 02, smoke deflector 03, smoke exhaust pipe 04.
Described cover body 01 surrounds smoke collecting chamber 02, and smoke deflector 03 is inverted U-shaped shape and is arranged in cover body 01. Smoke collecting chamber 02 is divided into upper exhaust gases passes 021, middle exhaust gases passes 022,023 3 exhaust gases passes of lower exhaust gases passes by smoke deflector 03, wherein go up exhaust gases passes 021, middle exhaust gases passes 022 is communicated with respectively smoke exhaust pipe 04, lower exhaust gases passes 023 is communicated with gas heater exhaust gases passes, smoke deflector 03 is provided with bloop 031, exhaust gases passes 022 during lower exhaust gases passes 023 is communicated with by bloop 031
Upper exhaust gases passes 021 is connected with lower exhaust gases passes 023, forms two-way discharge flue, that is: gas heater exhaust gases passes → lower exhaust gases passes 023 → bloop 031 → middle exhaust gases passes 022 → smoke exhaust pipe 04; And gas heater exhaust gases passes → lower exhaust gases passes 023 → upper exhaust gases passes 021 → smoke exhaust pipe 04. Therefore smoke collecting chamber 02 is divided three exhaust gases passes by described smoke deflector 03, to form two-way discharge flue, therefore there is the exhaust noise of effective elimination gas heater, improve the feature of the serviceability of product, and described smoke deflector 03 can be by a corrosion resistant plate bending and molding, and its manufacturing process is simple.
Fig. 3 and Fig. 4 show the cover body 01 of a specific embodiment according to the present invention. As Fig. 2, Fig. 3 show, cover body 01 comprises top board 011 and plate 012 around, and top board 011 and around plate 012 surround the smoke collecting chamber 02 with openend 024, and described openend 024 is communicated with gas heater exhaust gases passes. On plate 012, be provided with the exhaust opening 013 that is communicated with smoke exhaust pipe 04 around, top board 011 is near one end (downward direction is as shown in arrow A in Fig. 1) inclination 8 downwards of exhaust opening 013. Can effectively play like this effect of water conservancy diversion. The top board 011 of described cover body 01 is provided with to the lug boss 014 of smoke collecting chamber 02 projection, and described lug boss 014 is by forming cover body 01 punch process. More orderly to the water conservancy diversion effect of flue gas thus, and improve rectification effect.
Preferably, as shown in Figure 1 and Figure 2, smoke deflector 03 is fixed on exhaust opening 013 place, and stretches into smoke collecting chamber 02 and be inclined upwardly, and can prevent that ponding from flowing in smoke collecting chamber, heat exchanger, prevents flow backwards.
Preferably, as shown in Figure 1, Figure 2 with shown in Fig. 5, described bloop 031 is flanging bore, and the internal diameter of bloop 031 is 4mm, and bloop 031 can be distributed near exhaust opening 013 1 sides. Can further improve like this effect abating the noise.
Describe according to the gas heater of the embodiment of the present invention below with reference to Fig. 6. Gas heater comprises above-mentioned fume extractor 100, combustion chamber 200, heat exchanger 300.
Above-mentioned fume extractor 100 directly over described heat exchanger 300, smoke collecting chamber 02 is received the high-temperature flue gas that heat exchanger 300 discharges, and high-temperature flue gas is introduced to above-mentioned two-way discharge flue, finally discharges from smoke exhaust pipe 04. So can effectively eliminate the exhaust noise of gas heater. For convenience of the top that fume extractor 100 is arranged on to heat exchanger 300, cover body 01 is provided with flanging 015 at openend 024, by screw, flanging 015 is fixedly connected on to the top of heat exchanger 300. To facilitate the dismounting of fume extractor 100.
Above-described embodiment is exemplary, can not be interpreted as limitation of the present invention, and those of ordinary skill in the art can change above-described embodiment within the scope of the invention, amendment, replacement and modification.
